Social work practice consists of the professional application of social work values, principles, and techniques to one or more of the following ends:Helping people obtain tangible servicesProviding counseling and psychotherapy with individuals, families and groups. Helping communities or groups provide or improve social and health services Participating in relevant legislative processesFive themes:Social work concerns helping individuals, groups, or communities.Social work entails a solid foundation of values and principles.A firm basis of techniques and skills provides directions.Social works need to link people to recourses or advocate for service development for clients.Social workers participate legislative process to promote positive social changes.What is social welfare?Social welfare is a nation's system of programs, benefits, and services that help people meet those social, economic, educational, and health needs that are fundamental to the maintenance of society.Two Dimensions:What people get from society (programs, benefits and services?)How well their needs (social, economic, educational, and health) are being met How are social welfare and social work related?Debates on social welfare:Individual responsibility: you get you deserveSociety responsibilityWho should assume responsibility for people's social welfare?Residual, institutional, and developmental perspectives on social welfare.1. Residual ModelSocial welfare benefit and service should be supplied only when people fail to provide adequately for themselves.Blame the victim (fault and failure)For instance: social assistanceFamilies in need receive limited and temporary financial assistance until they can get back on their feet.2. Institutional modelPeople have a right to get benefit and service.For instance: public education, fire and police protectionEvery one can get these services.3. Developmental modelThis approach seeks to identify social interventions that have a positive impact on economic development.(1) Invest in education, nutrition and health care(2) In vest in physical facilities(3) help people in need engage in productive employment and self-employment.Political ideology: conservatives, liberalism and radicalismConservatism is the philosophy that individuals are responsible for themselves, government should provide minimal interference in people's lives, and change is generally unnecessary.Liberalism is the philosophy that government should be involved in the social, political and economic structure so that all people's rights and privileges are protected in the name of social justice.Radicalism is the philosophy that the social and political system as it stands is not structurally capable of truly providing social justice. The fundamental changes are necessary in the basic social and political structure to achieve truly fair and equal treatment.Fields of practice in social workWork with people in needs (children, youth, old people, the disable etc.)Work with some occupationThe continuum of social work careersDegree in social workBSW: prepare for the entry-level social workMSW: receive more specialized trainingDSW: teach at the college level or conduct researchSocial work builds on many disciplinespsychologysociologypolitical scienceeconomicsbiologypsychiatrycouncilcultural anthropologysocial workSocial workers demonstrate competenciesCompetencies are measurable practice behaviors that are comprised ofsufficient knowledge, skills, and values" and have the goal of practicing effective social work.Competency 1: identification as a professional social workerCompetency 2: the application of social work ethical principles to guide practice Competency 3: the application of critical thinking to inform professional judgmentsCompetency 4: engagement of diversity in practiceCompetency 5: the advancement of human rights and social economic justice.

Value and ethicsSocial worker is value-based profession.What is value?Value involves what you do and do not consider important and worthwhile, and also involve judgments and decisions about relative worth.What is Ethics?Ethics involve principles that specify what is good and what is bad. They clarify what should and should not be done Difference between value and ethics:Value determine what beliefs are appropriate. Ethics address what to do with or how to apply those beliefs to do the right thing.The importance of ethics2. Value and ethics for social workersSix core values for social workers:(1) Service(2) Social justice(3) Dignity and worth of the person(4) Importance of human relationships(5) Integrity(6) CompetenceSocial workers' ethical responsibilities to clients:(1) Self-determinationPractitioners should nurture and support client self-extermination ：each individual's right to make his or her own decisions.(2)Privacy and confidentiality(3) Conflict of interest and Dual relationshipsThe clients' best interests must be protected to the maximum extent possible.(4) Sexual relationshipSocial workers’ Ethical responsibilities to colleagues(1) Respect(2) Referral for servicesSocial Workers’ Ethical responsibilities in Practice settingsSocial workers' ethical responsibilities as professionalscompetenceagainst discriminationhonestnot solicit clients for the purpose of personal gainsSocial workers' ethical responsibilities to the social work profession.IntegrityResearchEvaluationSocial workers' ethical responsibilities to the broader society(1) Advocate for people's welfare(2) Ensure fair and equal access to resources and opportunities.(3) Respect cultural diversity.(4) Prevent discrimination against or exploiting peopleTranslation exercisesSocial workers must uphold client privacy and confidentiality. Privacy is the condition of being free from unauthorized observation or intrusion.We have established that confidentiality is the ethical principle that workers should not share information provided by a client or about a client unless they have the client's explicit permission to do so. There is more to confidentiality than may be immediately apparent.Confidentiality means more that not revealing information about clients to others. It also involves not asking for more information than is necessary, as well as informing clients about the limitations of confidentiality within the agency setting. Chapter 3 Empowerment and Human DiversityStereotype!Women are too emotional to make good supervisorsElderly people can't think well.Gay and lesbian people really want to be opposite gender.People with physical disabilities are unemployable.Discrimination, oppression, marginalization, alienation, stereotypes, and prejudiceDiscrimination is the act of treating people differently based on the fact that they belong to some group rather than on merit. Oppression involves putting extreme limitations and constraints on some person, group, or larger system. Marginalization is the condition of having less power and being viewed as less important than others in the society because of belonging to some group or having some characteristic.Alienation, related to marginalization, is the feeling that you don't fit in or aren't treated as well as others in the mainstream of society.A stereotype is a fixed mental picture of member of some specified group based on some attribute or attributes that reflect an overly simplified view of that group, without consideration or appreciation of individual differences.Prejudice is an opinion or prejudgment about an individual, group, or issue that is not based on fact.A major social work value involves the importance of people being treated fairly and equally.Populations-at-risk and social economic justiceDiversity emphasizes the similarity and dissimilarity between numerousgroups in society that have distinguishing characteristics.Populations-at-risk are people at greater risk of deprivation and unfair treatment because they share some identifiable characteristic that places them in diverse group.Factors: gender, age, religion, culture, disability, class, immigration statusSocial and economic justiceEmpowerment and a Strengths perspectiveEmpowerment is the process of increasing personal, interpersonal, or political power so that individuals can take action to improve their life situations.A strengths perspective:1. Every individual, group, family and community has strengths.2. Trauma and abuse, illness and struggle may be injurious but they may also be sources of challenge and opportunity.3. Social workers should assume that they do not know the upper limits of the capacity to grow and change and take individual, group, and community aspirations seriously.4. Social workers best serve clients by collaborating with when.5. Every environment is full of resources.Resiliency: seeking strength amid adversityThe ability of an individual, family, group, community, or organization to recover from adversity and resume functioning even when suffering serious trouble, confusion, or hardship.Resiliency involves two dimensions: risk factors and protective factors.Risk factors involve stressful life events or adverse environmental conditions that increase the vulnerability of individuals or other systems.Protective factors involve buffer, moderate, and protect against those vulnerabilities.Human DiversityRace and EthnicityRace implies a greater genetic determinant, whereas ethnicity often relates to cultural or national heritage.Culture and cultural competenceCulture is the sum total of life patterns passed on from generation to generation within a group of people and includes institutions, language, religious ideals, habits of thinking, and patterns of social and interpersonal relationships. Social workers need to have cultural competence to address the cultural needs of individuals, families, groups, and communities.叮叮⼩⽂库National Origin and immigration statusFour experiences which newcomer faced:Social isolationCultural shockCultural changeGoal-strivingclass or social classpolitical ideologygender, gender identity, and gender expressionSexual orientationHomosexual or heterosexual (bisexual)AgeDisabilityReligion and spiritualityChapter 4: Generalist practiceConcepts in the definition of generalist practice1.

Making equal responses to all people who come to an agency may reduce discrimination. Since negative valuations are so widespread, agencies may unthinkingly implement them. Consequently, we discourage potential clients from using the agency and they do not receive the equal treatment available.Chapter 7: Policy, Policy Analysis, Policy Practice, and Policy Advocacy Social welfare policyPolicy: rules that govern people's lives and dictate expectations for behavior.Social Welfare Policy: Laws and regulations that govern which social welfare programs exist, what categories of clients are served, and who qualifies for a given program.Agency Policy: standards adopted by organizations and programs that provide services.Social Welfare Policy Developmentphase 1Recognizing society's values about what is considered important or worthwhile.Phase 2Identifying problems and needs that require attention.Phase 3Identification of public opinion about an identified problem and people's related needs.Normative orientationphase 4Legislators confronted with a problem or need and swamped with public opinion undertake the complicated formulation of social welfare policy to address the issues.Phase 5Implementation through a social welfare program.Phase 6Social services are delivered by social workers and other staff in the context of social services agencies.Structural components of social welfare programs1.

Harmonizing Traditional Chinese and Modern Western Medicine: A Perspective from the USKa Kit Hui, M.D., F.A.C.P.Professor, Department of Medicine, UCLA School of Medicine; Director, UCLA Center for East-West MedicineThe current interest in traditional and complementary medicine in the United States is attracting attention in many parts of the community - the health care industry, governmental agencies, media and the public.1 An increasing number of insurers and managed care organizations are providing benefits for traditional medicine, a majority of U.S. medical schools now offer courses covering traditional medicine,2,3 and, as Eisenberg’s national studies have revealed, more people are using complementary therapies.4,5 To facilitate research on the effectiveness of alternative therapies, the National Center for Complementary and Alternative Medicine (NCCAM) received a budget of $50 million in 1999. Recognizing the need to encourage quality and quantity of scientific information on botanicals, as well as develop a systematic evaluation of safety and efficacy of dietary supplements, two research centers were also established this year to investigate the biological effects of botanicals.6Many patients are using traditional and modern medical paradigms concurrently, creating a need for the appropriate and smooth merger of the two medicines. The theories and techniques of traditional Chinese medicine (TCM) encompass most practices classified as complementary medicine in the United States, and have become increasingly important in the health care system.7 Traditional Chinese medicine is affordable, low tech, safe and effective when used appropriately. Ongoing research around the world on acupuncture, herbs, massage8,9 and Tai-Chi10,11 have shed light on some of the theories and practices of TCM. Evidence derived from vigorous research design12 as well as patient demand are fueling the merger of TCM with modern medicine at the clinical level, while more academic researchers and institutions are becoming more interested in the potential of integrating these two healing traditions. AcupunctureBased on evidence reviewed during the 1997 NIH Consensus Conference, the NIH Consensus Development Panel conservatively recommended that acupuncture may be used as an adjunct treatment, an alternative, or part of a comprehensive management program for a number of conditions. The panel ascertained that acupuncture can be used to treat post-operative and chemotherapy induced nausea and vomiting, as well as post-operative dental pain. It was also recommended as an adjunct treatment or an acceptable alternative for addiction, stroke rehabilitation, headache, menstrual cramps, tennis elbow, fibromyalgia, myofacial pain, osteoarthritis, low back pain, carpal tunnel syndrome, and asthma.13Future clinical trials that test acupuncture within the framework of traditional Chinese medicine are likely to provide a more appropriate and clinically meaningful assessment of acupuncture efficacy than the current generation of clinical trials which use a diagnosis framed primarily in biomedical terms. The scientific rigor of current research must continue; however, the NIH approach towards data analysis is too strict and limits potentially useful indications. Unlike drugs, acupuncture is more akin to surgery and physical therapy in terms of therapeuticmodalities. Hence, the evaluation of evidence for efficacy in acupuncture ought to be similar to these therapeutic interventions. For the time being, evidence based on large case series should be considered in determining recommendations for clinical practice while evidence derived from more vigorous research designs are being carried out.In elucidating the mechanisms of acupuncture and exploring its role in a variety of situations, innovative techniques such as fMRI (functional magnetic resonance imaging),14 PET (positron emission tomography), SPECT (single photon emission computer tomography), and MEG (magnetoencephalography) are beginning to be utilized. Studies on acupuncture in terms of its neuroanatomic and neurophysiological bases, bioelectrical properties, analgesia effects, and its role in regulation in areas such as gastrointestinal, immunological and cardiovascular functions are being carried out. More intense research with increased funding and scientific vigor, in an out of the US, will likely uncover additional areas where acupuncture may prove useful. This will further drive the adoption of acupuncture as a common therapeutic modality, not only in treatment, but also in prevention of disease and promotion of wellness. With technological advancement, innovative methods of acupuncture point stimulation will continue to be explored and perfected. Basic research on acupuncture will also help facilitate improved understanding of neuroscience and other aspects of human physiology and function.Because of heightened patient demand and better understanding of the role of acupuncture in health care through research and clinical experience, the biomedical establishment, health insurance industries, physicians and other health care providers are beginning to take an interest in acupuncture. In time, those who do not embrace acupuncture will be at a disadvantage. As the efficacy and cost saving potential of acupuncture is more widely recognized, there will be an even stronger push for more insurance companies, medical groups, and even Medicare to provide coverage of acupuncture treatment. We will witness acupuncture being utilized increasingly in outpatient settings, hospitals, rehabilitation units and hospices. An increasing number of physician acupuncturists as well as non-physician acupuncturists are working in different clinical settings. Some licensed acupuncturist specialists will work side by side with MDs in specialized areas.In the new millennium, the practice of acupuncture will be guided not only by traditional Chinese medicine concepts, but also by data generated through research advances in diverse fields such as neuroscience, molecular biology, chronobiology, computer and information science, energetics, integrative physiology and innovative clinical trial methodology.Herbs*Humans and animals have tested and used botanicals to relieve their suffering since ancient times. The appropriate use of Chinese herbs requires proper TCM diagnosis of the zheng (pathophysiological pattern) of the patient, correct selection of the corresponding therapeutic strategies and principles that guide the choice of herbs and herbal formulas. When appropriately prepared and used, herbs can be safe and effective. However, when used without proper guidance, a wide array of complications may result.* Modified from Hui, K.K. “Summary and Conclusions” (1999). Botanical Medicine: Efficacy, Quality Assurance, and Regulation. Eskinazi, D. (ed.) New York: Mary Ann Liebert, Inc.15Modern scientific investigations on plant-based medicine have been carried out in many parts of the world, including clinical trials of botanical combination products. Clinical research methodologists should take the theoretical construct and clinical approach of TCM into consideration when designing trials. Research designs such as randomized controlled trials have advantages and disadvantages in determining the efficacy of any therapeutic intervention, and can be carried out for botanicals, as seen by a study on herbal formulas for irritable bowel syndrome.16 Yet, we should seek approaches other than conducting a clinical trial for each product to evaluate safety and efficacy. Alternatives to RCTs include quasi-experiments, cohort studies, case-control studies, and “N = 1” trials. These methods have their advantages and limitations but may be more suited to the evaluation of herbal efficacy. The accurate measures of patient-centered outcomes both generic and disease-specific are important regardless of the design of the study. Above all, the appropriate study design depends on the research question and hypothesis being tested.Evaluating evidence is both difficult and subjective. The synthesis of evidence is completely dependent on the completeness of the literature search, which is often not available for foreign studies, as well as the accuracy of evaluation. Also, there are situations when neither RCTs nor database analyses separately can answer the question of interest due to different populations being used in the various kinds of studies. Consensus in the real world of health care often requires using information that is less stringent than so-called hard data. Realizing this, we should recognize the research and practice of herbal therapies in China, Korea and Japan when making recommendations for clinical practice. The pharmacological basis for many herbs have been determined in these studies and, as long as safety is assured, their findings should be considered when making recommendations. It is essential that researchers and practitioners be educated in both traditional and western medicines in order to perform research appropriately and treat patients effectively.Integrative East-West MedicineHarmonizing traditional medicine and modern medicine is more than utilizing modern research design or scientific technology to assess traditional medicine; it should include assessment of the intrinsic value of traditional medicine in society. Political, economic and social factors play as equally an important role as research and education in the eventual blending of the two healing traditions.On the clinical level, blending involves the integration of the concepts and techniques of the two systems -- modern medicine’s analytical, quantitative, mechanistic approach with the systemic, holistic, individualistic approach of TCM. This framework is applied through the process of diagnosis, prevention, treatment, and rehabilitation and guides the use of the appropriate techniques, allowing the strengths of TCM to compensate for the weaknesses of modern western medicine. As our graying society falls victim to an increasing number of chronic illnesses, we need a health paradigm that solves problems and provides affordable, effective health care for all. We believe that integrative East-West medicine is a candidate for such a model of medicine.References1.Workshop on Alternative Medicine, Alternative Medicine: Expanding Medical Horizons, AReport to the National Institutes of Health on Alternative Medical Systems and Practices in the United States, 1992.2.Wetzel, M.S., Eisenberg, D.M., and Kaptchuk, T.J.

医疗器械专业英语
医疗器械专业英语Medical Device Professional EnglishMedical devices play a crucial role in the diagnosis, treatment, and monitoring of various medical conditions. As the field of healthcare continues to evolve, it becomes increasingly important for professionals in the medical device industry to have a strong command of English, as it is the international language of communication in this industry. In this article, we will explore key terms, phrases, and concepts related to medical devices in English.1. Introduction to Medical DevicesMedical devices encompass a wide range of equipment, instruments, and apparatus used in healthcare settings. Examples include surgical instruments, diagnostic equipment, implantable devices, and prosthetic devices. Understanding the specific terminology related to medical devices is essential for effective communication in this field.2. Regulatory FrameworkThe production and distribution of medical devices are subject to strict regulations and standards to ensure patient safety and product efficacy. One notable regulation in many countries is the Medical Device Directive (MDD) or the In-Vitro Diagnostic Medical Device Directive (IVDD). These directives outline the requirements for placing medical devices on the market and the conformity assessment procedures that must be followed.3. Classification of Medical DevicesMedical devices are classified depending on their inherent risks and intended use. Common classification categories include Class I, IIa, IIb, and III. Class I devices have the lowest risk, while Class III devices pose the highest risk and often require more stringent regulatory scrutiny.4. Quality Management SystemsManufacturers of medical devices must comply with quality management systems (QMS) to ensure consistent product quality and compliance with regulatory requirements. The International Organization for Standardization (ISO) has developed standards such as ISO 13485:2016, which specifies the requirements for QMS in the medical device industry.5. Sterilization MethodsSterilization is a critical step in the production and preparation of medical devices to ensure they are free from viable microorganisms. Common sterilization methods include steam sterilization, ethylene oxide sterilization, and radiation sterilization. Each method has specific advantages and limitations, and the choice of sterilization method depends on the device's characteristics and intended use.6. BiocompatibilityBiocompatibility is the ability of a medical device to perform its intended function without eliciting adverse reactions in the patient's body. Ensuring the biocompatibility of medical devices is vital to prevent complications and ensure patient safety. Testing methods include cytotoxicity testing, sensitization testing, and hemocompatibility testing.7. International HarmonizationThe medical device industry is global, with devices being manufactured and sold across borders. To facilitate international trade and ensure consistent regulatory requirements, international harmonization efforts have been made. The Global Harmonization Task Force (GHTF) and its successor, the International Medical Device Regulators Forum (IMDRF), work towards aligning regulatory requirements and promoting international cooperation.8. Post-Market SurveillanceAfter a medical device is placed on the market, post-market surveillance is conducted to monitor the device's performance, identify potential safety issues, and ensure ongoing compliance with regulatory requirements. Adverse event reporting, complaint handling, and periodic safety updates are essential aspects of post-market surveillance.9. Unique Device Identification (UDI)To enhance traceability and improve patient safety, many countries have implemented UDI systems. The UDI is a unique numeric or alphanumeric code that identifies specific medical devices and provides key information such as the device's manufacturer, expiration date, and batch/lot number. The UDI facilitates rapid and accurate device identification during recalls or adverse event investigations.10. Emerging Trends in Medical DevicesThe medical device industry is constantly evolving, driven by advancements in technology and healthcare needs. Some notable emerging trends include the development of wearable devices, telemedicine applications, and personalized medicine approaches.

ECE R51.03第三版重大更新
UNECE World Forum forHarmonization of VehicleRegulations tightens vehicles noiselimits and adopts new testprocedure to measure themUNECE车辆法规统一论坛协会收紧车辆噪声限值并采取新的测试方案With rapid urbanization and growth of vehicle's fleet, more and more people are suffering from noise pollution. According to a recent study, 25 per cent of European citizens are exposed to average noise above the threshold established by WHO (55 dB) and road traffic is its main source. Thus, reduction of traffic noise is essential to improve the health and quality of life of people.随着快速城市化与车辆的总数的增长，越来越多的人饱受着噪音污染。
根据最近一项研究，25%的欧洲公民都暴露在世卫组织测试的平均噪声限值(55 分贝) 以上, 而道路交通是其主要的来源。
因此，降低交通噪声，改善人们的生活质量与健康至关重要。
On 24 June, the UNECE World Forum for Harmonization of Vehicle Regulations (WP.29) made a significant step towards achieving this goal by adopting a comprehensive revision of UN Regulation No. 51 on vehicle noise. 附件为最新法规：/fileadmin/DAM/trans/doc/2015/wp29/ECE-TRANS-WP29-2015-62e.pdfThe revised UN Regulation introduces reduced noise limits for vehicles (passenger cars, light commercial vehicles, light and heavy trucks and buses) that will enter into force in three steps from 2016 to 2024.在2015年6月24日，车辆法规协调的世界论坛（WP.29）为达成这个目标迈出了重要的一步，采用了全面修订联合国规定<<R 51车辆噪声>>经修订的联合国规定，介绍了降低车辆（载客汽车，轻型商用车，轻型和重型卡车和公共汽车）噪声限值的强制规定，将从2016年到2024年分三个阶段生效。
美术(绘画)作品分类及特点

张仃的焦墨山水画
中国画融诗词、歌赋、书法、绘画、印章于一炉，诗、书、画、印，相映生辉，这也是任何绘画艺术都没有的独特艺术形式。 Chinese painting is a combination in the same picture of the arts of poetry, calligraphy, painting, and seal engraving, which gives Chinese painting its unique qualities. 中国画中的一个重要品种是水墨画。水墨画特别讲究墨色的变化，有“墨分五色”之说，表明是在单纯的色彩中求丰富性和微妙性。墨因含水分之不同所造成的浓、淡、枯、湿、焦以及通过皴擦点染等手段，在画面上形成造型的和色彩的语汇，予人以美感。 One of the important categories of Chinese painting is ink-and-wash. What gives ink-and-wash paintings their unique flavour is that they make use of darkness or lightness, density or dilution to present the light and colour possessed by various objects, especially the particular effect formed between water, ink and unprocessed xuan paper. Hence, there is a saying “ Chinese Ink Representing Five Colors”.

An American National Standard is intended as a guide to aid the manufacturer, the consumer, and the general public. The existence of an American National Standard does not in any respect preclude anyone, whether he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. American National Standards are subject to periodic reviews and users are cautioned to obtain the latest editions.CAUTION NOTICE: This American National Standard may be revised or with-drawn at any time.

It incorporates the latest research in ESD waveform characterization and strives to ensure product quality through proper operation in actual equipment installations. The suggestions provided herein should not be construed as mandatory nor should they be blindly applied to all types of electronic equipment. Performance or acceptance test levels are not given in this document. The speciÞcation of performance or acceptance levels for any particular type of electronic equipment properly remains the prerogative of manufacturers and users of the particular equipment.Two models, the human body with metal object model (hand/metal) and the furniture discharge model are used for each testing methodology. Indirect contact testing to coupling planes is described for each testing methodology. Test descriptions for ßoor-standing and tabletop electronic equipment are given. Statistical cri-teria is given to determine the number of test trials based on the conÞdence factor desired and various pass/ fail categories.Although it was the intent to harmonize this ANSI guide wherever possible with IEC 801-2 (1991), the technical differences between the two guides are such that a complete harmonization is impossible. This ANSI guide includes information and guidance not included in that document, such as: furniture ESD simulation, statistical determination of the number of ESD discharges per test point, conÞdence level solution, and, probably most importantly, test waveforms more closely depicting the ESD waveforms as they occur in equipment installations.Because of the complexity of ESD, the variations in types of electronic equipment, and the many different actual use environments, it is a necessity for the reader to review and understand this guide in its entirety prior to commencing equipment testing.At the time this guide was completed, the working group under Subcommittee 1 of ANSI Committee C63, which developed this guide, had the following membership:David M.

ScopeThis guide describes methodologies for electrostatic discharge (ESD) testing of electronic equipment. The test methods and parameters described herein are chosen for standardization and repeatability of test results. This guide also recommends test criteria for evaluating equipment exposure and response to ESD. This guide does not set ESD test limits nor deal with equipment transient response to lightning, high-voltage breakdown, dielectric withstand, power line corona, or nuclear electromagnetic pulse.2. Overview2.1 GeneralAn ESD event occurs when the local electric Þeld between two bodies at different potentials exceeds the dielectric strength of air. When the ESD event occurs, the resulting current ßow produces both magnetic and electric Þelds.The nature of the ESD event has resulted in the following two testing philosophies:a)Air discharge testb)Contact discharge testThe goal in both cases is to determine the immunity of the equipment under test (EUT) to an ESD event.The air discharge simulator attempts to reproduce the actual ESD occurrence by creating a spark in air. This approach may not produce repeatable waveforms [B6], [B23].1 In the contact discharge simulator, the arc occurs inside the simulator under controlled conditions. This approach yields a repeatable waveform [B17]. The information in 7.1.1 and annex D will assist the user in determining the test method that is most suitable for the application.Further information about actual ESD events may be found in annex E of this guide and in IEEE Std C62.47-19922.1The numbers in brackets correspond to those in the bibliography in clause 10.2Information on references can be found in clause 3.ANSIC63.16-1993ANSI GUIDE FOR ELECTROST A TIC DISCHARGE TEST METHODOLOGIES 2.2 Comparison with other ESD standardsThis guide is written with reference to existing and draft international ESD standards, especially IEC 801-2 (1991) and CISPR 24. It is a guide, not a standard. As a guide, it should not be considered to be in conßict with these standards; rather, this guide will enhance them, improving ESD testing of equipment and the quality of that equipment as a result of the additional information presented. [Comparisons between IEC 801-2 (1991) and this guide are given in annex F.]This guide includes all of the main elements of the IEC 801-2 (1991) and CISPR 24 standards: the contact discharge method, the hand/metal source model, and the direct and indirect applications of ESD events to the EUT. This guide also includes information and material not found in these standards. This information is needed to complete the goals of ESD testing, primarilyÑTo ensure the quality of products and equipment through proper operation in actual-use environments (where ESD events occur)ÑTo have an ESD testing and evaluation procedure that is both realistic and workable, and that yields repeatable resultsThe key enhancements toward understanding ESD processes provided by this guide are as follows:a) A more complete treatment of the air discharge test method (including a more accurate speciÞcationand veriÞcation of the simulatorÕs performance)b)Information comparing actual ESD events as they occur in nature to the parameters recommended inthis guidec)Information comparing the parameters of this guide to those of IEC 801-2 (1991)d)Guidance on when to use the air discharge method and when to use the contact discharge method(including advantages and disadvantages of each method)e) A source model that simulates discharges from mobile ofÞce furnishingsf)Statistical guidance for selecting test voltage levels, number of test trials, and evaluation of testresults, instead of an arbitrary voltage limit and number of dischargesThe statistical guidance will help the user of this guide locate product susceptibility windows, which is crucial for testing any equipment that has time-variant operational states, such as information technology equipment (ITE).3.

Although the energy level of a single discharge at this voltage is below that which is considered lethal for a normal, healthy adult, this energy level can give the user an unpleasant shock. Therefore, there is an inherent danger when performing ESD tests.Operating and working around any high-voltage instrument or device requires a high degree of responsibility, care, and common sense. Normal high-voltage safety practices should be exercised when performing these tests. The ESD simulator manufacturerÕs safety practices should also be followed.6. Laboratory test conditionsThe intent of ESD testing in the laboratory is to simulate both the level and type of ESD occurrences that are experienced by the product in the Þeld in a manner that is representative of, but not necessarily identical to, actual ESD.In order to minimize the effect of environmental parameters on the test results, ESD testing should be carried out under the conditions deÞned in this clause.ANSI AND CRITERIA FOR ELECTRONIC EQUIPMENT C63.16-1993 6.1 Climatic conditionsESD testing should be performed under the following climatic conditions:a)Temperature: 15Ð27 ûC (59Ð80 ûF)b)Relative humidity (RH): < 50%c)Atmospheric pressure: 68Ð106 kPaNOTES1ÑStandard conditions are deÞned as sea level (101.3 kPa and 15 ûC). Then 106 kPa is -383 m and 68 kPa is +3236 m altitude. International conversion for 1 kPa is 0.145 lbf/in2 or 0.2953 inHg (typical reported atmospheric pressure mea-surement in the USA) and 10 mbar.2ÑTests can be performed outside the recommended climatic conditions. However, the results may be signiÞcantly affected with increased RH and variations in temperature.The actual environmental conditions existing during the test should be recorded on the data sheet.6.2 Air breakdown voltage test valueAir breakdown at a Þxed distance between arcing electrodes is approximately proportional to atmospheric pressure and inversely proportional to absolute (K) temperature. Therefore, when testing EUTs for air breakdown (external or internal with either test method), the ESD test voltage level should be changed to reßect the test equipment speciÞcation and the environmental test conditions. Typically, air breakdown at sea level will be about 40% higher than at 3000 m. Failure to change the test voltage to account for pressure vari-ation will create site-to-site immunity variations in the EUT air breakdown values.6.3 Electromagnetic conditionsThe ambient electromagnetic conditions should be such as not to inßuence the results of this test.6.4 Test site description6.4.1 GeneralCare should be exercised when selecting a site to perform ESD testing. The ESD impulse produces a broad spectral distribution of energy, and these emissions may cause damage or malfunction of unprotected equipment in the immediate area. Also, other equipment and activity in the immediate area can interfere with the ESD test. The ESD test site, therefore, should be located in an area that is of sufÞcient size to minimize interference.Accordingly, it is recommended that a clear-area radius of at least 1 m be provided around the EUT and to any other metallic structure, including walls, so as not to impact the ESD test. Where possible, the EUT should be placed in a dedicated room with electrical isolation from unrelated equipment. Shielded rooms are not recommended for use as ESD test sites because of the possibility of creating standing waves that may affect the test results.6.4.2 Size of ground reference plane (GRP)A GRP of sufÞcient size to provide a continuous reference for the EUT, ESD simulator, and operator should be provided as part of the test site. The GRP on the ßoor is extended beyond the edges of the EUT at least 0.5 m for equipment up to 1 m in height, as well as for a tabletop test. To capture all edge effects for equipment over 1 m in height, the GRP should extend beyond the EUT at least 50% of the height of the EUT. An optional insulator, not to exceed 5 mm in thickness, may be placed over the GRP. The GRP shouldANSIC63.16-1993ANSI GUIDE FOR ELECTROST A TIC DISCHARGE TEST METHODOLOGIES be connected to the protective grounding system. Local safety regulations should always be met. See 7.4.1 for EUT ground connections.NOTEÑThe GRP is not used during veriÞcation of the hand/metal ESD waveform for a lumped-element or hand-held simulator. A GRP should be used for a distributed capacitance simulator.7. Test methodsThe recommendations of this guide are based on the premise that products will be evaluated for ESD performance utilizing test simulation equipment that complies with the requirements delineated herein. Discharge phenomena considered essential to product ESD performance are as follows:a)Discharges from human bodies through a metallic object (hand/metal)b)Discharges from metallic furnitureThese ESD tests may be performed using air or contact ESD simulators. Human/touch ESD, though frequently encountered in the actual environment, is not delineated in this guide. See annex E.7.1 Test method guidanceTests may be performed utilizing air or contact ESD simulations for ESD events from humans holding small metal objects (hand/metal ESD) or from furniture. Subclauses 7.1.1 and 7.1.2 provide information relative to the use of these simulations.7.1.1 GuidanceÑAir or contact ESD methodsThe particular test method (air or contact ESD simulation) selected as appropriate for EUT evaluation should be determined by Þrst establishing an intended result for the information that will be gained from the ESD test. The user of this guide should review the advantages and disadvantages of each method, as described in annex D, prior to selecting which test method to use. Items a) through c) brießy overview the processes involved with the two approaches.a)For EUTs with conductive surfaces, either the air or contact discharge method can be used forapplying discharges.b)For EUTs with insulating surfaces, the air discharge method, by its nature, is predominantly used(see 7.5.4.4). The contact discharge test method may be used, but it will be an indirect test.c)When performing indirect ESD testing using coupling planes, either the air or contact test methodmay be used, but the contact discharge test method is preferred for reasons of repeatability.7.1.2 GuidanceÑHand/metal and furniture ESD simulationsESD test evaluations of EUTs may be performed utilizing hand/metal or furniture simulations. The application of ESD from either simulation on the EUT is intended to be concentrated as follows:a)In physical areas likely to be touched by humans for the hand/metal conditionb)In physical areas likely to be impacted by mobile furnishingsEither of these two simulations may additionally be applied to VCPs and HCPs for purposes of evaluating the EUT performance under the inßuence of indirect ESD.These two simulation methods are not mutually exclusive, although in practice they could result in redundant testing in certain EUT areas. It is recommended, in 7.5.3, that furniture ESD simulations be applied to EUT areas that are contained below a boundary height of 1 m above the ßoor surface (for ßoor-。

IntroductionKrippendorff's alpha coefficient, a widely recognized statistical measure in content analysis, is an essential tool for assessing the reliability of coding or categorization schemes employed in qualitative and quantitative research. Developed by Klaus Krippendorff, this coefficient offers a rigorous, comprehensive, and versatile approach to evaluating inter-rater agreement across multiple coders and various data types, including nominal, ordinal, interval, and ratio scales. This extensive analysis aims to delve into the multifaceted nature of Krippendorff's alpha, elucidating its significance in maintaining high-quality and stringent standards in research, particularly in light of its methodological robustness, versatility, sensitivity, and applicability across diverse disciplines.Methodological Robustness: Ensuring Data Integrity and ConsistencyOne of the primary strengths of Krippendorff's alpha lies in its methodological robustness, which contributes significantly to upholding high-quality research standards. Unlike simpler measures like percent agreement or Cohen's kappa, which may be prone to inflated estimates due to chance agreement, Krippendorff's alpha accounts for both random and systematic coder disagreements, providing a more accurate reflection of true inter-rater reliability.Firstly, it calculates expected disagreement based on the marginal distributions of the codes assigned, thereby adjusting for the probability of chance agreement that can arise from unequal code frequencies or imbalanced data. This feature ensures that the observed agreement among coders is not merely a result of chance, but rather reflects a genuine consensus on the coding scheme.Secondly, Krippendorff's alpha is adaptable to missing data, allowing researchers to handle incomplete coding without discarding valuable observations or resorting to ad-hoc imputation methods. By incorporating missing values into its calculation, it acknowledges the reality of incomplete coding in real-world research scenarios while still providing a reliable estimate of inter-rater agreement.Versatility Across Data Types and Analytical FrameworksThe versatility of Krippendorff's alpha is another key aspect that bolsters its utility in maintaining high-quality research standards. It is applicable to various data types, including nominal, ordinal, interval, and ratio scales, making it suitable for diverse research contexts where different levels of measurement are employed. This flexibility enables researchers to assess inter-rater reliability consistently, regardless of whether they are analyzing categorical variables, ordinal ratings, or continuous measurements.Furthermore, Krippendorff's alpha is agnostic to the analytical framework or theoretical perspective guiding the research. Whether the study employs a deductive, inductive, or abductive approach, or is grounded in qualitative, quantitative, or mixed-methods research designs, the coefficient remains a relevant and reliable measure of inter-rater agreement. This universality fosters cross-disciplinary dialogue and allows for meaningful comparisons between studies employing different methodologies, contributing to the overall rigor and standardization of research practices.Sensitivity to Coding Complexity and Sample SizeKrippendorff's alpha is highly sensitive to both the complexity of the coding task and the sample size, ensuring that it accurately reflects the challenges faced by coders and the adequacy of the data for drawing reliable conclusions. In complex coding tasks with many categories or intricate decision rules, the coefficient will naturally tend to be lower due to the increased potential for disagreement among coders. This responsiveness to coding complexity encourages researchers to refine their coding schemes, provide clearer guidelines, or consider alternative analytical approaches when faced with low reliability scores.Regarding sample size, Krippendorff's alpha is known to converge to a stable value as the number of units coded increases, providing a more accurate estimate of inter-rater reliability with larger datasets. This property discourages researchers from drawing premature conclusions based on small samples andpromotes the collection of sufficient data to ensure reliable results.Applicability Across Disciplines and Research ContextsThe broad applicability of Krippendorff's alpha across various disciplines and research contexts further underscores its role in maintaining high-quality, standardized research practices. It has been widely adopted in fields such as sociology, psychology, communication studies, linguistics, anthropology, and information science, among others, for assessing the reliability of coding in content analysis, discourse analysis, sentiment analysis, and textual data mining.In these diverse settings, Krippendorff's alpha serves as a common metric for evaluating inter-rater agreement, facilitating comparisons across studies, and promoting the development of standardized coding practices within each discipline. Moreover, its ability to accommodate multivariate data structures, such as dyadic or triadic interactions, and its compatibility with hierarchical or clustered data, makes it suitable for complex research designs that often characterize interdisciplinary research.ConclusionKrippendorff's alpha coefficient embodies the high-quality and stringent standards required in contemporary research through its methodological robustness, versatility across data types and analytical frameworks, sensitivity to coding complexity and sample size, and broad applicability across disciplines and research contexts. By offering a rigorous, comprehensive, and adaptable measure of inter-rater agreement, it empowers researchers to assess the reliability of their coding schemes, refine their analytical strategies, and contribute to the standardization and harmonization of research practices across diverse fields. As such, Krippendorff's alpha stands as a cornerstone of qualitative and quantitative research, underpinning the pursuit of scientific rigor, accuracy, and reproducibility in the face of ever-evolving research challenges and complexities.。
