In recent years, leisure time has received increasing attention in Korean society. Despite the growing interest, however, there are very few studies that explored shared leisure time, especially among married couples. In this light, the present study examined variations in shared leisure time by demographic characteristics and associations between shared leisure time and quality of marital relationship. We used the third wave of the national data KLoWF (Korean Longitudinal Survey of Women and Families, 9,997 19-64 years old women). The study sample included 5,965 married women with no prior history of divorce. Results showed that Korean wives reported very little shared leisure time with their husbands. Given that the mean of the shared leisure time reported by employed women was significantly lower than that of the un-employed, we speculated that the time constraint may be one of the major barriers to having leisure time with one's spouse among Korean married couples. Married women in their 30's had the most frequent couple leisure time. The younger wives in their 20s had more cultural leisure time with their husbands, but sharing outdoor leisure time was not related to their age. The higher level of education for women was associated with greater shared active leisure time. However, visiting a husband's family often took place regardless of the wives' education level. After controlling for age, years of education, job status and annual family income, shared active leisure time (i.e., cultural activity and exercise) was positively related to marital satisfaction. Visiting one's own family, however, was not considered a leisure activity for Korean wives. Rather, frequent family visits were related to lower marital satisfaction. Findings shed light on how leisure life of married women with spouses are intertwined with not only their socioeconomic status and but also marital relationship in culturally unique ways.

Maritime accidents caused by a ship include collisions, sinking, stranding and fire etc. This study is intending to consider fire accidents among such diverse marine accidents. It is much likely that various sorts of fires break out because crewmen are living in a narrow space for long periods of time consequent on the ship's characteristic of sailing on the sea. According to the ship fire survey, about 50% of the total fire accidents occurred at an engine room, and the main fire origin was analyzed to be oil. In addition, ship fire breaks out in the order of baggage racks and living quarter. In short, the survey indicates that all sorts of fires belonging to A, B, C and D-class have occurred. This study, targeting an actual passenger ship 'A', found the response time to evacuation, during which the people on board a ship recognize the outbreak of fire, and act, and the travel time for evacuation which is the actual travel time. In addition, this study carried out a simulation through the special program for fire analysis - FDS (Fire Dynamics Simulator) in order to find the effective evacuation time, i.e. life survival time. Particularly, this study did comparative analysis of the influence on the survival of passengers and crew based on the collected simulation data by fire size and sort. As a result of the analysis, it was found that when examining the only actual evacuation movement time excepting the response time to evacuation, people are safe by completing evacuation before the effective evacuation time only in case fire size is 100Kw among all sorts of fires. In other words, in case of the outbreak of fire more than 1 MW, it was found to fail to meet evacuation safety regardless of fire size.

Purpose: The Act on Hospice and Palliative Care and Decisions on Life-Sustaining Treatment for Patients at the End of Life came into force in February 2018 in Korea. This study reviews the practices of end-of-life care for patients who withdrew or withheld life-sustaining treatment at a tertiary care hospital, addresses the limitations of the law, and discusses necessary steps to promote patient-centered self-determination. Methods: We retrospectively analyzed the medical records of patients who died after agreeing to withhold life-sustaining treatment in 2018 at our university hospital. The cause of death, the intensity of end-of-life care, and other characteristics were reviewed and statistically analyzed. Results: Of a total of 334 patients, 231 (69%) died from cancer. The decision to stop life-sustaining treatment was made by family members for 178 patients overall (53.3%) and for 101 (43.7%) cancer patients, regardless of the patient's wishes. When the patient decided to stop life-sustaining treatment, the time from the authorization to withhold life-sustaining treatment to death was longer than when the decision was made by family members (28.7±41.3 vs 10.5±23.2 days, P<0.001). Conclusion: In many cases, the decision to discontinue life-sustaining treatment was made by the family, not by the patient. In order to protect human dignity based on the patients' self-determination, it is necessary for patients to understand their disease based on careful explanations from physicians. Ongoing survey-based research will be necessary in the future.

This study analyzed the impact of leisure activities on school life satisfaction in the cultural rights and self-determination of teenagers who spend most of their time in school in the college entrance exam-oriented climate, and examined the effects of happiness and life satisfaction on the school life satisfaction through a process macro applying Bias Corrected Bootstrapping in these relationships. For research purposes, 2,590 cohorts in the first year of the 2018 Korea Children and Youth Panel Survey were analyzed through process macros. The result was that leisure life had a significant effect on school life satisfaction. It was also found that happiness and satisfaction in life affect satisfaction, and happiness and satisfaction in life affect satisfaction in school life and serve as a medium. This study confirmed that teenagers' participation in leisure activities greatly affects school life satisfaction and that happiness and life satisfaction have a mediating effect on school life satisfaction. In addition, we could recognize the importance of leisure activities to the satisfaction of school life of teenagers, and find it necessary to develop and provide various program graphs of schools and communities for happiness and satisfaction in life. This study verified that the participation of leisure activities of adolescents has a significant effect on school life satisfaction, and that happiness and life satisfaction have a mediating effect on school life satisfaction. In addition, we could recognize the importance of leisure activities to the satisfaction of school life of teenagers, and find it necessary to develop and provide various program graphs of schools and communities for happiness and satisfaction in life. Therefore, this research is believed to be possible to contribute to academic and practical programs for youth leisure activities and school life relationships, and to make policy suggestions for the development and participation of various leisure activities in order to fully enjoy and protect youth's rights to culture and self-determination of leisure activities.

Objective: This study was to perform to identify the distribution characteristics and related factors of work-related low back pain among manufacturing workers in Korea. Methods: We analyzed the third(2011) through sixth(2020) Korean Working Conditions Survey. This study examined changes in the prevalence of work-related low back pain among manufacturing workers and related factors, including demographic characteristics and working conditions. Results: The prevalence of work-related low back pain showed a general tendency to increase during the study periods except for the 5th wave. The prevalence of work-related low back pain was higher in women than in men. The prevalence increased with increasing age and decreased with higher educational attainment. This trend was observed in all survey waves. The prevalence ratios for work-related low back pain according to working conditions varied over the survey period. In general, workers with manual jobs, long working hours, and exposure to tired or painful postures showed relatively higher prevalence ratios than did their counterparts. Providing Information on health and safety, perception that work affects health, and experience of presenteeism were identified as influencing factors for work-related low back pain. Although the working environment is improving, work-related back pain is on the rise. A multifaceted study on risk factors for work-related low back pain is needed. Conclusion: Work-related low back pain is a significant factor affecting the working population's quality of life. The prevalence of work-related low back pain showed a tendency to increase during the study periods. A multifaceted study on risk factors for work-related low back pain is needed.

The concept of 'Employer branding' (EB) - one effective and sustainable strategy to attract and retain talent - has received a lot of attention from researchers and business managers. This concept becomes more meaningful when the 'war of talent' takes place in an extremely fierce manner in Vietnam as well as around the world. However, this concept is rather new; as a result, many points related to 'EB' scales should be improved, especially in Vietnamese context. Therefore, this study focuses on developing and confirming the EB scale in the context of Vietnam. Based on EB theory, this research applies the mixed research method: qualitative methods (expert interview and group discussion) and quantitative method (questionnaire survey of 937 respondents). EB is demonstrated to be a quadratic concept, consisting of the following 10 dimensions: Corporate social responsibility (CSR), Promotion (PRO), Work-Life Balance Satisfaction (WLSA), Education (EDU), Behavior-based Family interference with work (WLBE), Travel opportunities (TRA), Time-based work interference with family (WLTI), Teamwork (GRO), Supporting (SUP), and Strain-based family interference with work (WLST) with 58 observed variables. Based on the survey towards the employees in enterprises and organizations in Vietnam, the analysis results affirm that this scale ensures efficiency, reliability, unidirectionality and convergent values.

As the quality of life improves, people want to live in more pleasant environment with beautiful trees, clean air and water. They are keenly interested in environmental issues as well as living environment of apartment which is a trademark of modern life. With this situation, the function and roles of landscaping trees have been recognized as a critical factor to improve living environment. As people have asked for more demands on those trees, it has raised more issues on the defect of trees and is required the solution to those issues. So, the purpose of this study was to survey the reasons of defects and find out those solutions. The data on defects in 1990s was referenced to the reports issued by SH Corporation in 1994 and 1997. The data on defects in 2000s are collected from March, 2006 to May 2006 based on the survey for apartments already constructed by Korea Housing Corporation. The results of the survey were shown that, in the year of 1994, landscaping trees causing high rate of defects were Acer buergerianum (92%), Pinus densiflora(85.7%), Celtis sinensis(80%), Cydonia sinensis(75%) and Diospyros kaki(66.6%), and in the year of 1997, landscaping trees causing high rate of defect were Ziziphus jujuba(100%), Cornus alba(65.2%), Diospyros kaki(60%), Thuja occidentalis(60%), and Metasequoia glyptostroboides(42%). And, in the year of 2006, landscaping trees causing high rate of defect were Sophora japonica(100%), Taxus cuspidata(80%), Magnoila quinquepeta (75%), Acer palmatum(62.5%) and Ginkgo biloba(50%). Because the reasons of defects were various according to the conditions including the climate, location, time and landscaping trees carried into the work area, we present the problems and solutions to those defects. Since the landscaping trees are living creatures, the factors of defects were various and complicated according to the site condition. So, in the period of warranty, contractor should designate the tree manger who can recognize the situation and take suitable action within timely manner.

Objectives: This study investigated the current use of university foodservice among Chinese international students in Korea, focusing on the relationship between the frequency of university foodservice use and their dietary life. Methods: An online survey was conducted on 452 Chinese international students from February 6 to 12, 2020. The respondents were classified into "the Low-frequency group" (< one time/week; n=144), "the Mid-frequency group" (one-two times/week; n=133), and "the High-frequency group" (≥ three times/week; n=175) according to their frequency of using university foodservice. The dietary life was compared among the three groups. Binominal logistic regression models were constructed to determine the associations between the frequency of university foodservice use and the changes in dietary life. Results: More than 2/3 (68.1%) of the respondents used the university foodservice at least once per week. Chinese international students who were males and Han Chinese people, lived on campus, had stayed longer in Korea, and had no cooking facilities tended to use the university foodservice more often. The level of satisfaction with the university foodservice was not high (3.52 out of 5-points). Only 20% ate meals three times per day, and only 22% ate breakfast almost every day. The frequencies of overeating and skipping meals increased after studying in Korea. The frequency of university foodservice use, along with the length of residence in Korea, was associated with these negative changes in dietary life. Overeating (OR=2.11) and skipping meals (OR=1.79) were more likely to increase after studying in Korea in the Mid-frequency group than in the High-frequency group. Conclusions: The frequency of university foodservice use was associated with the dietary life of Chinese international students in Korea. A high frequency (i.e. ≥ three times/week) of using university foodservice may positively affect the dietary life of Chinese international students in Korea.
