This study was to investigate the social workers' psycho·social experiences and roles during the end-of-life care process in elderly long-term care facilities. As a result of data analysis through in-depth interviews, social workers experienced great exhaustion and burnout due to frequent death experiences during the end-of-life care process, and expressed regret for not being able to provide better service for the deceased and longing for loved ones. And in the event of a sudden death, social workers would undergo criticism and complaints. The main roles of social workers during end-of-life care were to contact and communicate with family members when signs of death appeared and support them after the death. The necessity of standardized manuals and education for end-of-life care, a recharging program and support group to prevent burnout of social workers, and a legal safety net for emergency preparedness and emergency measures were suggested. The necessity of death preparation education, hospice care, and advance medical directive was also emphasized for the dignified death of the elderly.

Some bogie frames manufactured in 1999, 2000 year have the fatal problem. Three or four years later, the cracked end beam among them have discovered in 2002, 2003 year. The crack situation of the end beam have a bad effect on brake system. In that case, the cars would be in danger of derailment. To improve the end beam, a research of covering the whole field of welded type bogie frame was started. Main line real tests were performed at Young-Dong line. The stress of main positions for bogie frame was measured. Also up-down direction and left-right direction vibration acceleration of the bogie frame were measured. At this time the tests were performed for the three types bogie. The test result concludes that the crack cause of the end beam is not brake load but vibration at running mainly. It is estimated that the life of the improved car which end beam reinforced is safe within the car permitted life(25 years). The improvement methods of the end beam are presented by construction modification, parts modification. The integrity evaluation is inspected by analysis the real line test results, the improvement methods of the end beam.

Life Cycle Assessment(LCA) is an environmental assessment tool for evaluating environmental burdens associated with products, processes and activities from the raw material acquisition stage to the end-of-life stage. End-of-life stage as well as other processes requires a reliant database in order to increase the confidence in the LCA results. In this study, the flow of Personal Computer(as PC) in the end-of-life stage was examined and the database of two scenarios has been established, i.e. one is part reuse and the other is no part reuse, in the end-of-life phase of PC. Also, key environmental issues were identified by carrying out LCA on a PC in the end-of-life phase for eight environmental impact categories. The 'ozone layer depletion' contributes the highest environmental impact due to generation of $Cl_2$ gas during the incineration of waste plastics. In addition, the scenario 1(part reuse) is more environmentally sound than the scenario 2(no part reuse) when comparing two scenarios.

Background: Emerging evidence suggests that endothelial-to-mesenchymal transition (EndMT) in endothelial dysfunction due to persistent inflammation is a key component and emerging concept in the pathogenesis of vascular diseases. Ginsenoside Rg3 (Rg3), an active compound from red ginseng, has been known to be important for vascular homeostasis. However, the effect of Rg3 on inflammation-induced EndMT has never been reported. Here, we hypothesize that Rg3 might reverse the inflammation-induced EndMT and serve as a novel therapeutic strategy for vascular diseases. Methods: EndMT was examined under an inflammatory condition mediated by the NOD1 agonist, γ-d-glutamyl-meso-diaminopimelic acid (iE-DAP), treatment in human umbilical vein endothelial cells. The expression of EndMT markers was determined by Western blot analysis, real-time polymerase chain reaction, and immunocytochemistry. The underlying mechanisms of Rg3-mediated EndMT regulation were investigated by modulating the microRNA expression. Results: The NOD1 agonist, iE-DAP, led to a fibroblast-like morphology change with a decrease in the expression of endothelial markers and an increase in the expression of the mesenchymal marker, namely EndMT. On the other hand, Rg3 markedly attenuated the iE-DAP-induced EndMT and preserved the endothelial phenotype. Mechanically, miR-139 was downregulated in cells with iE-DAP-induced EndMT and partly reversed in response to Rg3 via the regulation of NF-κB signaling, suggesting that the Rg3-miR-139-5p-NF-κB axis is a key mediator in iE-DAP-induced EndMT. Conclusion: These results suggest, for the first time, that Rg3 can be used to inhibit inflammation-induced EndMT and may be a novel therapeutic option against EndMT-associated vascular diseases.

Purpose: This study was performed to identify the level of stress perceived by nurses who attend dying patients in the cancer care unit; their understanding regarding end-of-life care and related training needs. Methods: A cross-sectional descriptive study was conducted with 151 nurses stationed at the cancer care units of four general hospitals located in Seoul and Gyeonggi province in Korea. Data were collected using self-reported questionnaires and the response rate was 96%. The data were analyzed using t-test, ANOVA and Pearson's correlation analysis. SPSS 12.0 was used for data analysis. Results: Nurses experienced a high level of stress in the end-of-life care settings. Their understanding of end-of-life care was above the mid-point of the scale while their training needs for end-of-life care was relatively high. The more experienced the nurses were, the more stressed they were, particularly due to excessive workload. Nurses who served longer in the cancer unit tended to show greater needs for end-of-life care training. Conclusion: This study found nurses perform end-of-life care with a high level of stress but with insufficient understanding, and thus, showed great needs for related training. Such findings can be useful to develop an end-of-life care training program for nurses.

This research is a descriptive correlation research for comprehending the end of life care stresses, work environment, and reduction of nurses in geriatric hospitals and analyzing the factors influencing their burnout. We recruited 195 nurses from 8 geriatric hospitals in B metropolitan city and collected data on the end of life care stress, work environment and reduction using organized questionnaires. The data were analyzed with SPSS WIN 21.0 program. The average grade of end life care stress was $3.84{\pm}0.56$, nursing work environment $3.25{\pm}0.60$, and burnout $2.93{\pm}0.52$. There was a positive correlation between the end of life care stress and reduction(r=.206, p=.004) but a negative correlation between nursing work environment and reduction(r=-.431, p<.001). The most influential factor on the reduction was nursing satisfaction(${\beta}=-.302$), followed by work environment(${\beta}=-.294$), age(${\beta}=.286$), duty style(${\beta}=-.17$), and end of life care stress(${\beta}=.164$). The overall explanatory power was 41.2%.These results suggest that in order to minimize the reduction of nurses in geriatric hospitals, the provision of a supportive work environment which enhances their pride and responsibility as a nurse and offers incentives is required with effective distribution of duties, development of the end of life nursing education and administrative tools for reducing their stress.

Purpose: The aim of this descriptive study was to identify factors influencing quality of life among family caregivers of non-cancer patients at the end-of-life stage. Methods: A cross-sectional survey was conducted using a questionnaire. Participants included 172 family caregivers caring for non-cancer patients. Data were collected from April to May 2016 and analyzed with descriptive statistics, an independent t-test, one-way ANOVA, Pearson's correlation coefficient, and a hierarchical regression analysis using the SPSS/WIN 24.0 program. Results: The mean of the participants' quality of life was 51.70±9.98. Factors influencing quality of life among family caregivers were spiritual care (𝛽=-.45, p=.021), coordination among family members or relatives (𝛽=-.27, p=.029), and psychological support (𝛽=-.04, p=.031). The explanatory power of the model was 21.0%. Conclusion: The findings of this study suggest that care needs; spiritual care, coordination among family members or relatives, and psychological support are important factors for family caregivers' quality of life. To improve quality of life among family caregivers who are taking care of non-cancer patients at the end-of-life stage, national systems establishing comprehensive support considering the respective care needs of patients are crucial.

Purpose: The purpose of this study was to investigate end-of-life care preferences of employees working in a university hospital. Methods: Of 650 eligible employees that were approached, 607 employees (386 nurses, 93 physicians, and 128 general staff) completed the Korean version of Preferences for Care Near the End of Life (PCEOL-K). Results: Among 5 dimensions of the PECOL-K, "Pain" was the most preferred care dimension and "Decision making by health care professional" was the least preferred care dimension. The item that received the highest mean score was "I want to let nature guide my dying and I do not want my life to be artificially prolonged in any way", and the lowest item was "I want health care providers to make all decisions about my care". As preferred care near the end of life, nurses gave lower scores to the life sustaining treatment and decision making by health care profession than physicians and general staff. Compared to physicians and nurses, general staff preferred the decision making by health care professional and by family. Conclusion: The results show that adequate pain relief is the most preferred care at the end of life among hospital employees and non-medical personnel preferred decision making by others.

The present study aims to assess the excess induced reactivity in a Miniature Neutron Source Reactor (MNSR) for a Beyond Design Basis Accident (BDBA) scenario. The BDBA scenario as defined in the Safety Analysis Report (SAR) of the reactor involves sticking of the control rod and filling of the inner and outer irradiation sites with water. At the end of the MNSR core life, 10.95 cm of Beryllium is added to the top of the core as a reflector which affects some neutronic parameters such as effective delayed neutrons fraction (${\beta}_{eff}$), the reactivity worth of inner and outer irradiation sites that are filled with water and the reactivity worth of the control rod. Given those influences and changes, new neutronic calculations are required to be able to demonstrate the reactor safety. Therefore, a validated MCNPX model is used to calculate all neutronic parameters at the end of the reactor core life. The calculations show that the induced reactivity in the BDBA scenario increases at the end of core life to $7.90{\pm}0.01mk$ which is significantly higher than the induced reactivity of 6.80 mk given in the SAR of MNSR for the same scenario but at the beginning of the core's life. Also this value is 3.90 mk higher than the maximum allowable operational limit (i.e. 4.00 mk).
