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).

The purpose of this study was to investigate the correlation between ethical dilemma, end-of-life care stress and burnout of the nurses in long term care hospitals and descriptive correlations to identify factors affecting burnout. The subjects of study were 143 nurses who are working in the seven long-term-care hospitals in G-do and had more than one experience of end-of-life nursing care, understood the research items and agreed to participate in the research. In this study, it was founded that end-of-life care stress, age, job position, and end-of-life care education were found to be influential factors affecting burnout of the nurses in long-term care hospitals. As a result, age and occupation, end - of - life nursing education, and end - of - life stress were found to be factors affecting nurses' burnout. Therefore, in order to prevent and alleviate burnout of long-term care hospital nurses, a systematic intervention program that manages stress related to end-of-life nursing care is needed.

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.

The present study proposes the definition of service life and the end-of-life criterion for bridge maintenance. Bridges begin to deteriorate as soon as they are put into service. Effective bridge maintenance requires sound understanding of the deterioration mechanism as well as the expected service life. In order to determine the expected service life of a bridge for effective bridge maintenance, it is necessary to have a clear definition of service life and end-of-life. However, service life can be viewed from several perspectives based on literature review. The end of a bridge's life can be also defined by more than one perspective or performance measure. This study presents definition of service life which can be used for bridge maintenance and the end-of life criterion using the performance measure such as a damage score. The regression model can predict an average service life of bridges using the proposed end-of-life criterion.

This study is a descriptive research study to identify the relationship between the performance of end-of-Life care of ICU nurses, moral distress, ethical climate, difficulties in end-of-life care, and positive psychological capital. Data were collected with structured questionnaires from 144 ICU nurses at a university hospital in J city, Gyeongnam, from October to November in 2020, and analyzed using SPSS/WIN 21.0. The subjects' performance of end-of-life care of ICU nurses is significantly different depending on marital status, experiences of end-of-life care education. The variables that had a significant effect on the performance of end-of-life care among ICU nurses were positive psychological capital and difficulties in end-of-life care. The explanatory power was 24.8%. Based on these results, it is necessary to intervention program and education to reduce difficulties in end-of-life care and increase positive psychological capital for ICU nurses.

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).
