Coastal dunes have many environmental and ecological socio-economic importances; various human activities, however, have impaired their structures and functions over the years. In 2016, environmental survey on coastal sand dune was carried out to report the present status and update the coastal sand dune list in 2001. This research analyzed the survey data in terms of geomorphological and socio-economic aspects. A list of the 189 coastal sand dune and information was updated by province. A 36.5% reduction in coastal sand dune area have been identified for using agricultural land, development area since the approximately 1940-50s. Development area in coastal sand dune covered small area as 5%, the use intensity was relatively hard. Furthermore, the difference by province also showed. Approximately 80% of the development area was concentrated in 20% of total sand dune several sand dune. It is generally accepted that coastal sand dunes were exposed high development pressure. However the result means that the general brief dose not apply for all sand dune. Therefore, characteristics of each sand dune should be analyzed and concerned the diverse management plans.

Objects. There was an increase in obese population due to eating habits resulted in modernization of lifestyle and the change of the tendency to conduct the physical activity, in order words, the reduction in the range of kinetic energy. Obesity is viewed as a major risk factor for serious health problems, including heart disease, high blood pressure, stroke, diabetes, and certain forms of cancer as well as for psychological and social problems owing to our fat-phobic society. In the present study, we investigate the weight loss thanks to giving Handayulso-tang(HD) medication of Taeum-in to induced obesity rats and its effects on lipid metabolism, given that their behavior patterns are changed according to their constitution. Methods: The extracts of Handayulso-tang was orally administered to the rats of HD group 200mg/200g of rats weight every day for 6 weeks, and the control group were fed with equal amount of saline. And measured the body weight and total cholesterol, triglyceride, free fatty acid and total lipid contents in serum in obese rats. Results: 1. The body weight in HD group were decreased. 2. The contents of serum total cholesterol and triglyceride in HD group were decreased and statistically showed the significant difference compared with the control group. 3. The contents of serum free fatty acid and total lipid in HD group were decreased, but did not statistically show the significant difference compared with the control group. Conclusion: Based on the above results, we know that Handayulso-tang have effects on the decrease of the body weight and the contents of serum total cholesterol, triglyceride, free fatty acid and total lipid So it could be concluded that Handayulso-tang can help the treatment of obesity.

Telometer is a supplementary filming device that improves the image quality and minimizes the motion unsharpness by enhancing the reproducibility of diagnostic images because it applies constant pressure (force) to the affected area. The stress-radiogram which is widely used to provide the o-bjective quantitative stability of knee ligament is reported in literature as the most suitable method to evaluate the stability of ligament and it is advised to use the Telometer. In order to evaluate the image reproducibility of the Telometer, the collateral ligament which is the most vulnerable among the ligaments consisting of the knee joint, the stress-radiogram was executed in the order of the Telometer, the push pull gauge and the conventional stress radiogram. Then, SPSS (Statistical Package for the Social Science) for Windows 22.0 was used for comparison and evaluation. According to the results of comparison and evaluation, the standard errors and standard deviations became smaller in the order of the Telometer, the push pull gauge, the conventional stress radiogram while the image reproducibility was higher in the order of the Telometer, the push pull gauge, the conventional stress radiogram. Therefore, it is considered that the use of the TELOS for stress-radiogram would enhance the quality of patient diagnostic images and the work performance of radiologists.

The purpose of this study was to explore the effects of family life stress and family values on marital stability among middle-aged couples. The subjects included a total of 302 men and women aged 45-64 who had been married for more than 20 years and were living in Seoul. The collected data were statistically analyzed with the SPSS 21.0 Package. First, Cronbach's alpha was calculated to measure the reliability of the scale that assessed the variables of the research model. Then, mean and standard deviation were calculated to determine the degrees of family life stress, family values, and marital stability among the subjects. Finally, a hierarchical multiple regression analysis was performed to identify factors that affected the subjects' marital stability. The results revealed that the level of family life stress in middle-aged married men and women was slightly higher than the mean value. Of all the sub-scales of family life stress, the subjects were found to experience the most stress from factors related to financial pressure, followed by family relationships, a sense of loss within a family, and work-family compatibility. Therefore, financial problems were one of the critical stressors for middle-aged married couples. Also, for this demographic, the levels of family values and marital stability were higher than the medians. The factors affecting marital stability in middle-aged couples were identified to be family relationship stress, financial stress, subjective economic status, family values, stress related to work-familycompatibility,religion,andage.Thedegreeofmaritalstabilitywashigherinmiddle-agedcouplesa stheirstresslevelsfromfamilyrelationshipsandfinancialproblemswerelower.Moreover,thehigherthes ubjectiveeconomicstatusandthemoretraditionalthefamilyvalues,thehigherthedegreeofmaritalstabili ty.Finally,marriedcoupleswhowerereligioushadalowerlevelofstressfromwork-family compatibility, and the younger the couples, the higher the degree of marital stability.

The purpose of this study was to analyze in-depth the nurses' experience of hospital work and the factors affecting career interruption of nurses. For this purpose, 20 inactive nurses aged 26-55 participated in interviews about their experience as nurses, characteristics of nursing work, and reasons for retirement, and applied the analysis method of Colaizzi among phenomenological research methods. The analysis resulted in 104 significant statements, 17 formulated meanings, 6 clusters of theme, and 2 categories. The two categories are nursing work characteristics and work environment characteristics. In the characteristics of nursing work, there are four clusters of theme of 'time pressure', 'lack of autonomy', 'physical and emotional labor', 'low wage increase', and in the characteristics of nursing work environment, there are two clusters of theme of 'physical environment' and 'human environment'. Therefore, in order to improve the nurse career interruption, efforts should be made to alleviate excessive work intensity, raise the appropriate level of pay and provide a safe working environment.

School closures during the coronavirus disease 2019 (COVID-19) pandemic have been outlined in studies from different disciplines, including economics, sociology, mathematical modeling, epidemiology, and public health. In this review, we discuss the implications of school closures in the context of the current COVID-19 pandemic. Modeling studies of the effects of school closures, largely derived from the pandemic influenza model, on severe acute respiratory syndrome coronavirus 2 produced conflicting results. Earlier studies assessed the risk of school reopening by modeling transmission across schools and communities; however, it remains unclear whether the risk is due to increased transmission in adults or children. The empirical findings of the impact of school closures on COVID-19 outbreaks suggest no clear effect, likely because of heterogeneity in community infection pressure, differences in school closure strategies, or the use of multiple interventions. The benefits of school closings are unclear and not readily quantifiable; however, they must be weighed against the potential high social costs, which can also negatively affect the health of this generation.

Our daily lives have changed a lot because of the COVID-19 pandemic. This is essential to reduce the spread of COVID-19 due to public health measures such as social distancing. At the same time, however, they are exposed to depression, anxiety disorders, depressive disorders, trauma and stress-related disorders. For this, we developed an application that can check HRV data and stress index by measuring ECG and PPG based on a Smart Watch device that can measure bio-signals in real time. In the case of the developed application, the heart rate is measured and displayed in real time to deliver basic exercise information by measuring exercise, steps and calories, and total distance, and smoothly based on blood pressure, heart rate, and HRV data as a measurement program. Through this, I believe that the IoT Smart Stress Care Application, which can manage mental health by itself, will be helpful to patients with stress and depressive trauma disorders.

Purpose: This study aimed to examine the process from occurrence of a hospital nurse's suicide to workers' compensation approval, responses of the parties involved, issues debated during approval deliberations, and significant policy changes resulting from the incident. Methods: We conducted in-depth interviews with involved parties and collected various documents, including newspaper articles, forum proceedings, and the agency report on determination of workers' compensation. Content analysis was performed on the collected data. Results: A Joint Task Force continuously reported its progress and findings through mass media such as newspaper, radio, and TV. These activities exerted pressure on a government agency to conduct an occupational disease review and significantly impacted the workers' compensation approval. The agency recognized associations between the hospital's inadequate nurse training and the suicide but did not confirm the excessive overtime and workplace harassment experienced by the nurse as causes of the suicide. This case's media coverage and impact resulted in a law prohibiting workplace harassment and a hospital system dedicating at least one nurse to training activities. Conclusions: This incident had a significant social impact as the first case of workers' compensation approval for a hospital nurse's suicide. However, the case produced no structural changes in nurses' working conditions such as heavy workloads.

Purpose: This descriptive phenomenological study aimed to explore the lived experience and meaning of pregnant women's adaptation. Methods: Ten pregnant women from an ongoing Pregnant Couples' Cohort Study agreed to participate in this study. The data were collected through telephone in-depth interviews regarding what they experienced and felt about pregnancy adaptation. The qualitative data were analyzed using Giorgi's method of descriptive phenomenology. Results: Five core situation components were extracted from the raw data, along with 12 themes and 33 focal meanings. The five core situations were 1) first recognizing the pregnancy, 2) pregnancy-related changes, (3) the upcoming birth, 4) the postpartum period, and 5) parenting. The 12 themes were as follows: "anxiety, pressure, and embarrassment due to pregnancy," "efforts to adapt to physical changes," "efforts to adapt to the psychological difficulties of pregnancy," "efforts to adapt to the financial burden and role changes caused by pregnancy," "connecting with the fetus," "adapting to a new marital relationship centering on the baby," "the frustration of childbirth," "fear of childbirth," "postpartum care, need help with lactation planning," "parenting beyond what I imagined," "dad's willingness to participate in parenting," and "career disconnect and consideration of workplace needs." Conclusion: We identified that pregnant women experience adaptation in physical, psychological, relational, and social aspects. The thematic clusters identified can be used to develop nursing interventions to promote women's adaptation to pregnancy.

Purpose: This study aims to identify factors affecting the adoption of e-commerce by household businesses in Vietnam's food and beverage industry. Research design, data and methodology: The integrated TAM and TOE frameworks and ten hypotheses were developed to test the relationship between relevant factors. A cross-sectional survey was conducted to collect valid data from 992 respondents who run F&B household businesses in Vietnam. Results: The empirical research results confirm all proposed hypotheses that e-commerce adoption is affected by the perceived usefulness, the perceived ease of use, vendor support partners, social expectancy, competitive pressure, subjective norm, and household resources. Meanwhile, technical readiness, environment readiness, and organization readiness are intermediate variables that influence the implementation of e-commerce in food and beverage distribution. Conclusions: The findings suggest effective orientations to foster the food and beverage e-trading practice for household businesses in developing countries. Accordingly, to encourage private household businesses to adopt e-commerce, it is necessary to focus on improving business resources, technology readiness, environment readiness, and organization readiness through raising awareness of usefulness, benefits, perceived ease of use, and increased support of vendor partners. Future research can focus on improving the efficiency of e-commerce applications in F&B distribution for both household businesses and larger-scale enterprises.
