The first and the longest criminal indictment case of Korean medico-legal battle, so called BORAMAE Hospital Incident, was finally on its end by Korean Supreme Court's decision on June 24, 2004, after 7 years long legal dispute via Seoul District Court and Seoul Superior Appeal Court's decision. Boramae Hospital case was the first Korean legal case of Withdrawing Life-sustaining treatment of mechanical respirator on 58 years old Extradural Hematoma victim who was on Respirator under Coma after multi-organ failure postoperatively(APACHE II score: 34-39). Two physicians who have involved patient's care and had helped to make discharge the Near-death patient to home after repeated demand of patient's wife, due to economic reason, were sentenced as homicidal crime. This review article will discuss the following items with the review of US cases, Quinlan(1976), Nancy Cruzan(1990), Barber (1983), Helen Wanglie(1990), Baby K (1994) and Baby L cases, along with Official Statement of ATS and other Academic dignitaries of US and World.: [1] Details of Boramae Hospital incident, medical facts description and legal language of homicidal crime sentence.

본 연구는 새로운 AC PDP(Plasma Display Panel)용 멀티레벨 에너지 회수회로에 관한 연구로서, 기존 멀티레벨 구동회로의 장점을 그대로 유지하면서 문제점을 해결한 새로운 멀티레벨 구동회로를 제안한다. 기존의 멀티레벨 구동회로는 Weber회로의 하드스위칭 문제를 개선하였지만 공진 인덕터에 기생공진전류가 존재하고 Vs/2유지구간이 존재한다. 제안한 회로는 기존 회로에 비해 인덕터의 수를 반으로 줄여 회로를 간단히 하고 공진 인덕터의 기생 공진전류와 Vs/2유지구간을 제거하였으며 CIM(Current Injection Method)을 사용하여 하드스위칭 문제를 해결하였다. 또한 풀브리지 구동회로에 직렬 연결된 스위칭 소자에 NPC(Neutral Point Clamping)기법을 적용하여 각 스위칭 소자에 전압이 균등하게 분배되도록 하였다. 그리고 제안회로의 동작을 모드별로 해석하였으며, PSpice 프로그램으로 시뮬레이션하고 회로를 구성하여 실험함으로써 제안한 회로의 유용성을 입증하였다.

Objectives: The aim of this study was to construct and verify a structural equation model of advance directive intent among a Korean group in their middle-age. Methods: Data were collected between May 1 and 30, 2017, from 398 people. The endogenous and exogenous variables of the hypothetical model consisted of elderly parents' care burden, health status, attitude towards withdrawal of life sustaining treatment, advance directive efficacy, and advance directive intent. The collected data were analyzed using the SPSS/WIN 24.0 and Mplus 7.4. Results: The hypothetical model demonstrated a good fit: χ2=223.79(df=109, p<.001), CMIN/df=2.05 CFI=.96, TLI=.96, RMSEA=.05, SRMR=.06. Elderly parents' care burden and health status showed statistically significant direct effects with attitude toward withdrawal of life sustaining treatment(β=.17, p=.001; β=.21, p<.001) and advance directive efficacy(β=.11, p=.040; β=.19, p=.002), respectively. Attitude toward withdrawal of life sustaining treatment and advance directive efficacy showed statistically significant direct effects on advance directive intent(β=.15, p=.007; β=.48, p<.001). Elderly parents' care burden and health status had a significant indirect effect on advance directive intent through attitude toward withdrawal of life sustaining treatment(β=.01, p=.041; β=.05, p=.036) and advance directive efficacy(β=.06, p=.049; β=.16, p=.006), respectively. The variables accounted for 26.1% of advance directive intent of the Korean group in their middle-age. Conclusion: It is necessary to develop an advance directive education program based on variables affecting advance directive intent for individuals in their middle-age.

A novel current-fed energy-recovery sustaining driver (CFERSD) for a PDP is proposed in this paper. Its main idea is to recover the energy stored in the PDP or to inject the input source energy to the PDP by using the current source built-up in the energy recovery inductor. This method provides zero-voltage-switching (ZVS) of all main power switches, the reduction of EMI, and more improved operational voltage margins with the aid of the discharge current compensation. In addition, since the current flowing through the energy recovery inductor can compensate the plasma discharge current flowing through the conducting power switches, the current stress through all main power switches can be considerably reduced. Furthermore, it features a low conduction loss and fast transient time. Operations, features and design considerations are presented and verified experimentally on a 1020${\times}$l06mm sized PDP, 50kHz-switching frequency, and sustaining voltage 140V based prototype.

The application of the knowledge from the Human Genome Project to clinical medicine will be through both industrial drug development and the application of pharmacogenomics (PG) to patient care. The slow uptake of clinical innovations into clinical practice can be frustrating, but understanding the history of acceptance and sustaining medical innovation is critically important to position PG to succeed. This primarily means that PG tests must have legitimacy; they must be thoroughly validated, must be cost-effective, must be widely accepted by medical practitioners, must be supported by public policy, and must have a way of being easily incorporated into current medical practice. They must also lead to actionalble decisions by health care providers for their patients. Innovative PG assays should be tested in the best US laboratories, and reimbursement for testing must be accepted at the federal and state level. The companies providing these PG tests should be capable of supporting the interpretation and use of the test throughout medical practice. Advances such as the addition of PG information to drug labeling and the routine use of validated biomarkers to determine choice of cancer chemotherapy have been made. The PG research community must pay attention to the principles that have been previously described for acceptance and sustaining medical innovations in order for PG to be widely accepted in clinical medical practice.

Purpose: This study aimed to explore the factors influencing attitudes toward withdrawal of life-sustaining treatment (WLST) in adolescents. Methods: This study used a descriptive research design. A structured questionnaire was administered to 185 adolescents. Data were analyzed based on t-tests, analysis of variance, Pearson's correlation coefficient, and multiple regression using the IBM SPSS 20.0. Statistical package. Results: There was a negative correlation between attitudes toward WLST and respect for life (r=-.188, p=.010). Knowing about life-sustaining treatment (β=-0.30, p<.001), experience of WLST education (β=0.21, p=.003), experience of respect for life education (β=-0.16, p=.021), and experience of death (family or acquaintance) (β=-0.13, p=.039) explained 16.7% (F=8.39, p<.001) of the variance in attitudes toward WLST. The respect for life did not affect attitudes toward WLST (β=-0.07, p=.347). Conclusion: The study findings suggest that WLST in adolescents is different from that of adults. Further research is needed to develop strategies for sound and positive attitudes toward WLST in adolescents.

현재 AC-PDP(Plasma Disphay Panel) 의 기술은 급속히 발전하고 있는 추세이지만 아직도 몇가지 문제로 인해 이를 해결하기 위한 다각적인 접근이 이루어지고 있다. 동화상 윤곽의 제거 광(光) 대비 향상을 통한 화질의 개선 신뢰도 및 전력 효율을 개선하는 등의 문제가 여기에 해당되며 그 중에서도 특히 전력 효율의 관점에서 40 인치 이상의 대형화면을 지향한는 PDP 기술에서 가장 큰 약점으로 분류되고 있는 수백 와트(watt)에 이르는 전려 소모를 CRT 수준이 200[W] 미만으로 낮추어 것이 시급한 당면 과제이다. 전려 효율을 향상시키기 위해서 PDP의 발광효율을 높이는 것과 함께 기체 장번과는 직접적인 관련이 없이 구동과정시 발생하게 되는 불필요한 전력소모를 최소화 하여야 한다. 본 논문에서는 이러한 전력 소모를 최소화하기 위한 새로운 형태의 고효율 에너지 회수 회로를 제안하고 시뮬레이션을 통해 그 동작을 확인하였다. 또 이는 회로를 설제 7.5인치 패널에 인가하고, 200［kHz］에서 실험하여 제안한 고효율 에너지 회수회로의 타당성을 검증하였다.

Purpose: The purpose of current study was to investigate nurses and physicians' attitudes towards withdrawal of life-sustaining treatment (LST) and knowledge about withdrawal of LST guideline by Korean Medical Association. Methods: Data were collected from 345 nurses and 88 physicians using a self-report questionnaire and analyzed using descriptive statistics, independent t-test or ${\chi}2$ test. Results: Participants' attitudes towards withdrawal of LST were positive and there was no significant difference between nurses and physicians. Nurses' knowledge of the guideline for withdrawal of LST was significantly higher than that of physicians, whereas physicians' knowledge of the purpose of the guideline was significantly higher than that of nurses. Conclusions: Nurses and physicians' knowledge of and attitudes toward withdrawal of LST may affect the quality of life of patients and their families. The result of this study may be helpful to design a program for improving the perception on LST of healthcare providers.
