Purpose: This study aimed to identify levels of perception and performance of end-oflife care among nurses and to investigate correlations between perception and performance. Methods: This cross-sectional descriptive survey included 321 nurses from a tertiary hospital in Seoul, Korea. The participants had at least 6 months of work experience and had been involved in end-of-life care at least once, in either ward or intensive care unit settings. A structured questionnaire was utilized to assess their perception and performance of endof-life care. Results: The mean score for perception of end-of-life care was 3.23±0.34, while the score for performance of end-of-life care was 3.08±0.34. There was a significant positive correlation between nurses' perception of end-of-life care and their performance in this area (r=0.78, P<0.001). Conclusion: It is necessary to change perceptions regarding end-of-life care and to develop systematic and standardized education programs including content such as assessing the hydration status of dying patients, evaluating mental aspects such as suicidal ideation, and providing spiritual care for nurses working in end-of-life departments.

An end-of-life strategy is concerned with how to disassemble a product and what to do with each of the resultingdisassembled parts. A sound understanding of the end-of-life strategy at the early design stage could improve theease of disassembly and recycling in an efficient and effective manner. Therefore, the end-of-life decisionmaking for environmental conscious design has become a great concern to product manufacturers.We introduce a novel concept ofeco-architecture which represents a scheme by which the physical componentsare allocated to end-of-life modules. An end-of-life module is a physical chunk of connected components or afeasible subassembly which can be simultaneously processed by the same end-of-life option without furtherdisassembly. In this paper, a method for analyzing the eco-architecture of a product at the configuration designstage is proposed. It produces an optimal eco-architecture under the given environmental regulations. To dealwith the case ofa complex product, the method is extended for analyzing hierarchical eco-architecture.

Purpose: The purpose of this study was to investigate pediatric nurses' perceptions regarding in end-of-life care and turnover intention. Methods: A cross-sectional descriptive study was performed among 111 hospital nurses. Pediatric nurses' perceptions of obstacles and supportive behaviors were measured using the Pediatric Nurses' Perceptions of End of Life Care Questionnaire which was translated into Korean and turnover intention was measured using the Korean Nurse Turnover Intention Scale (K-NTIS). Results: The supportive behavior with the highest perceived magnitude was 'Physicians who are compassionate, but very clear about prognosis.' The obstacle with the highest perceived magnitude was 'Instigating painful treatments when there is no hope of recovery.' Pediatric nurses' perceptions of obstacles in end-of-life care showed statistically significant differences depending on whether nurses received end-of-life care education (t=2.02, p=.046). The perception of obstacles in end-of-life care was positively correlated with turnover intention (intensity r=.28, p=.002) (frequency r=.20, p=.027). Conclusion: These results suggest that pediatric nurses' perception of obstacles and supportive behaviors in end-of-life care need to be assessed when considering turnover intention. Furthermore, psychological counseling should be offered to nurses to prevent burnout and reduce moral distress which is correlated with the turnover rate.

In this study, we predict the generation of end-of-life photovoltaic modules when Feed in Tariff applied, in Republic of Korea. Based on the installation of photovoltaic modules, we prepared three different senarios in order to estimate the generation of end-of-life photovoltaic modules. The senarios are i) early worn-out, ii) mid worn-out and iii) late-worn out senario. We selected the mid worn-out senario to estimated the amount of end-of-life photovoltaic modules in this study. Establishment of the end-of-life module generation scenario predicted generation of end-of-life photovoltaic module, and forecasted generation amount of end-of-life module to which Feed in Tariff was applied in consideration of installed photovoltaic modules installed by Feed in Tariff support. The generation of Feed in Tariff-applied end-of-life modules increased from 2021 to 2025 compared to without Feed in Tariff, and since then, the Feed in Tariff-applied end-of-life modules were generated as waste modules during the relevant period (2021 ~ 2025).

본 연구의 목적은 요양병원 간호사를 대상으로 윤리적 딜레마, 임종간호스트레스 및 소진의 관계와 윤리적 딜레마와 임종간호스트레스가 소진에 미치는 영향을 파악하고자 함이다. 본 연구의 대상자는 경상남도에 위치한 7개 노인요양병원에 근무하고 임종간호 경험이 한 번 이상 있으며 연구의 목적을 이해하고 연구 참여에 동의한 간호사 143명을 대상으로 구조화된 설문지를 이용하여 설문조사하였다. 본 연구결과 연령과 직위, 임종간호교육, 임종간호스트레스가 요양병원 간호사의 소진에 영향을 미치는 요인으로 확인되었다. 따라서 요양병원간호사의 소진을 예방하고 완화시키기 위해 임종간호 관련 교육과 함께 스트레스를 관리하는 체계적인 중재프로그램이 필요할 것이다.

End-of-life care competencies have been perceived as important and essential, so it has been suggested that end-of-life care be studied in undergraduate medical education. However, end-of-life care curriculum has mostly focused on acquisition of knowledge and skills rather than attitudes. Therefore, we aimed to explore whether education about death affects medical students' attitudes towards care for dying patients and perception of death anxiety, meaning in life, and self-esteem. A total of 15 first- or second-year medical students were surveyed with questionnaires before and after completing a 6-week death education course. Paired data analysis showed that participants' attitudes towards caring for terminally ill patients and their caregivers improved significantly (t=-2.84, p=0.013) with an effect size of 0.73. In contrast, no significant changes were found in death anxiety, meaning in life, or self-esteem. All participants agreed that formal teaching about death and dying must be encouraged in medical schools. Our results suggest that death education may positively influence attitudes towards end-of-life care. Although replication with larger samples is necessary, this preliminary finding may support the importance of developmentally appropriate end-of-life care education in medical schools.

Purpose: The purpose of this study was to explore clinical nurse's reported conflict experience toward end-of-life medical decision making. Methods: Data were collected by in-depth interviews with eight nurses from three different wards of university hospital in D city of Korea. Conventional qualitative analysis was used to analyze the data. Results: Results were three major themes and twelve categories from the analysis. The three major themes were prioritization of treatment, non-disclosure of diagnosis, and hierarchical and power relations. Conclusion: The results of this study suggest that shared decision making in end of life among patient, family members, physician, and nurse may contribute to improve end-of-life care performance as well as dignified dying of patient in end of life.

본 논문에서는 교량의 유지관리를 위한 사용수명의 정의 및 수명 종료를 제안하였다. 먼저 국내외 교량의 수명용어 관련 현황을 바탕으로 교량의 사용수명을 정립하였다. 교량의 사용수명이란 '교량이 유지관리 통해 요구하는 수준의 기능을 발휘하는 기간'으로 정의 하였다. 그리고 사용수명 종료 제안을 위해 국내외 수명종료 기준을 분석하고 교량에 발생 가능한 수명 종료 유형을 분류하여 수명종료를 제안하였다. 사용수명 종료 제안 시, 교량의 성능지표(결함도 점수)를 활용하였으며 상태등급 'D'등급의 중간값인 결함도 점수 0.64를 수명종료 기준으로 제안하였다. 민감도 분석을 실시하여 제안된 교량의 사용수명 종료 시점의 타당성을 검토하였다. 마지막으로 제안한 사용수명 종료 시점을 활용하여 현재 고속도로 교량의 평균 사용수명을 70.8년으로 추정하였다.

Although $N{\alpha}$-terminal acetylation (Nt-acetylation) is a pervasive protein modification in eukaryotes, its general functions in a majority of proteins are poorly understood. In 2010, it was discovered that Nt-acetylation creates a specific protein degradation signal that is targeted by a new class of the N-end rule proteolytic system, called the Ac/N-end rule pathway. Here, we review recent advances in our understanding of the mechanism and biological functions of the Ac/N-end rule pathway, and its crosstalk with the Arg/N-end rule pathway (the classical N-end rule pathway).
