Nuts are cholesterol free with high poly-unsaturated fatty acids(PUFA) and have lower intakes of sodium than non-consumers, and thus they can decrease blood pressure. Hypertension is a common primary diagnosis in Korea. Because of extending exposure to 24-hour raised blood pressure and heart rate hypertension is likely to be caused by prolonged short sleep durations. This study examined the relationship between nut consumption and hypertension according to sleep duration among Korean adult. Based on data from the 2010-2016 Korea National Health and Nutrition Examination Survey(KNHANES), the final analytic sample(n=25,359) was used for current analysis. The dietary intake was assessed through a 24-hour recall method. Associations of nut consumption with sleep duration and hypertension were determined using multiple logistic regression with odds ratio(95% CI). All the analyses were carried out in SAS version 9.4, and the significance level was set at p<0.05. With increasing nut intake, the prevalence of hypertension significantly decreased(p for trend=0.02). After controlling for sleep duration, the nut consumption showed significant association with the prevalence of hypertension when sleep duration was 6 to 6.9 h per day(p for trend=0.03) or 7 to 7.9 h per day(p for trend=0.03). In conclusion, dietary total nut intake was found to be significantly associated with the prevalence of hypertension.

Purpose: This study examined the mediation effects of dietary habits, nutrient intake, daily life in the relationship between the working hours of Korean shift workers and metabolic syndrome. Methods: Data were collected from the sixth (2013-2015) Korea National Health and Nutrition Examination Survey (KNHANES). The stochastic regression imputation was used to fill missing data. Statistical analysis was performed in Korean shift workers with metabolic syndrome using the SPSS 24 program for Windows and a structural equation model (SEM) using an analysis of moment structure (AMOS) 21.0 package. Results: The model fitted the data well in terms of the goodness of fit index (GFI) = 0.939, root mean square error of approximation (RMSEA) = 0.025, normed fit index (NFI) = 0.917, Tucker-Lewis index (TLI) = 0.984, comparative fit index (CFI) = 0.987, and adjusted goodness of fit index (AGFI) = 0.915. Specific mediation effect of dietary habits (p = 0.023) was statistically significant in the impact of the working hours of shift workers on nutrient intake, and specific mediation effect of daily life (p = 0.019) was statistically significant in the impact of the working hours of shift workers on metabolic syndrome. On the other hand, the dietary habits, nutrient intake and daily life had no significant multiple mediator effects on the working hours of shift workers with metabolic syndrome. Conclusion: The appropriate model suggests that working hours have direct effect on the daily life, which has the mediation effect on the risk of metabolic syndrome in shift workers.

This study examines the welfare dynamics in Korea under the scheme of National Basic Livelihood Protection Program(NBLP). Data are drawn from Korean Welfare Panel study 2005~2007. Main findings are summarized as follows. First, the exit probabilities show a declining tendency with time on welfare increases. If the exit probabilities indeed decline over time, the earlier years on welfare deserve more interest in the policy perspective. Moreover, the vast majority of recipients are long-termers. Further efforts are needed to increase self-sufficiency through providing genuine opportunity and necessary support for recipients. Second, out-of-poverty exit and out-of-system exit are quite different in their properties. The results from the multivariate analysis confirm that the dropouts through out-of-system exit are virtually the same with those who remain on welfare. These results imply that the government should not resort to the negative policy proposals such as time limit and strengthening sanctions. Third, several explanatory variables have anticipated effect on welfare exit probabilities. Age, education, health, marital status, the presence of children, employment status have a certain level of impact on exit, with the only exception of gender. Since the identification of the determinants can facilitate sensible targeting on the potential leavers, these results have some implications on policy proposals.

This study investigates the change of everyday's labor and leisure time in South Korea during the last two decades in which her economy has been changed from manufacturing-oriented industry to services or technology and knowledge-oriented industry. Generally speaking, the changing patterns of everyday's labor and leisure time in South Korea from 1981 to 2000 are very complex and dynamic. So it is very careful for us to simply assert the fact that everyday's labor time is decreased and everyday's leisure time is increased due to the deindustrialization of a capitalist country. Specifically, the changes of everyday's labor and leisure time in South Korea are varied in terms of socio-economic and spatial perspective. The labor time of all kinds of occupations has been increased at the weekday during the last two decades, but the leisure time of those except technical occupation has been decreased at the weekend. The socio-economy of South Korea after the 1990s became dependent on more educated workers than less ones. Also the more educated people work hard at the weekday, but they get more leisure time at the weekend. In terms of spatial perspectives, the South Korean economy has become dependent on the workers in cities, particularly large ones more than those in rural regions because of the rapidly established industrialization and urbanization after the early 1980s. The time of people's spatial movement is directly proportional to the levels of education both at the weekday and the weekend during the last two decades.

산업화로 인한 급속한 경제성장과 증가하는 여성들의 사회진출은 의생활에서 보다 편 하고 간소화된 생활양식을 추구하게 되고, 이에따라 의복의 구입에 있어서도 맞춤복보다 는 시간, 경제면에서 유리한 기성복을 선호하게 되었다. 불특정다수를 위한 기성복의 생산에 있어서 개개인의 체형에 보다 적합성이 좋은 제품의 개발을 위해 다수인의 다항 목계측치에 근거한 치수체계의 설정은 무엇보다 중요한 문제가 된다. 우리나라에서는 1979년 공업진흥청에 의해 제 1차 국민표준체위조사가 실시되었으며, 1986년에는 제 2차 조사가 실시되어 그 결과를 토대로 한국 공업규격의 의류치수 규격이 제정 발표되었다. 그러나 이것은 연령에 따른 신체적 변화를 고려한 체형분류가 되어 있지 않으며, 제품 호수에 따라 동일한 간격을 둔 체계였다. 1992년에는 제 3차 국민표준체위조사가 실시 되어 그 결과가 발표되었다. 의복은 인체계측에 의한 신체 각 부위의 치수와 형태를 기초로 2차원적인 소재에 적절한 원형을 사용하여 재단, 봉제과정을 거쳐 3차원의 입체 로 구성하고 인체에 대응시킨 것이므로 기성복에 대하여 소비자의 치수적합성을 만족시 키기 위해서는 체형의 특징을 고려해야 할 것이다. 특히, 성장이 완료된 성인 여성은 출산후 중년에 접어들면서 신체적 특성이 변하여 체형이 바뀌는 경향이 있으므로 전 여성에대한 의류치수규격보다는 연령의 구분과 체형의 분류가 필요하다고 본다. 더우기 의류업체들의 판매대상의 세분화는 이를 더욱 뒷받침해주고 있다. 따라서 체형의 분류는 의복 치수 규격에 적용되어 의복의 종류에 따라 대다수의 불특정 다수 에게 보다 잘 맞는 의복 치수를 제공할 것이며, 그 치수의 정확성을 증대시키게 된다. 김성득(1991)은 소비자의 기성복에 대한 구매확률을 높이기 위해서는 규격치를 등간격 으로 하기 보다는 소비자의 분포밀도가 높은 곳일수록 규격치 간격들을 좁게 설정함으 로써 생산자 입장에서 총손실을 줄이고, 상대적 비용절감효과를 갖게할 수 있다고 하였다. 따라서 본 연구에서는 성인 여성기성복의 치수적합성을 높이기위하여 출산 후 중년에 접어 들면서 체형이 변화되는 것을 고려하여 연령을 분류하고(18세-34세, 30세-51세), 각 연령 집단에 따른 체형을 각각 3가지로 분류하였다. 이에 따라 의복 생산시의 총손실을 줄이기위한 상의, 하의생산시 필요한 부위별 최적규격치 간격을 제시하였다.

The 4th industrial revolution technology is developing people's lives more efficiently. GIS provided on the Internet services such as traffic information and time information makes people getting more quickly to destination. National geographic information service(NGIS) and each local government are making basic data to investigate SOC accessibility for analyzing optimal point. To construct the shortest distance, the accessibility from the starting point to the arrival point is analyzed. Applying road network map, the starting point and the ending point, the shortest distance, the optimal accessibility is calculated by using Dijkstra algorithm. The analysis information from multiple starting points to multiple destinations was required more than 3 steps of manual analysis to decide the position for the optimal point, within about 0.1% error. It took more time to process the many-to-many (M×N) calculation, requiring at least 32G memory specification of the computer. If an optimal proximity analysis service is provided at a desired location more versatile, it is possible to efficiently analyze locations that are vulnerable to business start-up and living facilities access, and facility selection for the public.

A total of 5,597 Korean subjects aged 20-64 years were analyzed using the KNHANES 2013-2015. Among the subjects, 41.1% of males and 5.5% of females were smokers, and risk of developing metabolic syndrome in smokers was significantly increased in men with age, alcohol, physical activity, obesity, and sleep(aOR 1.785, 95% CI 1.004-3.174), whereas it was not significantly higher in women. As a result of analyzing the difference of average nutrient intake according to smoking and metabolic syndrome, the energy, retinol and vitamin C intake were significant when age and gender were corrected in the smoker and metabolic syndrome group. In this study, we found that smoking behavior and metabolic syndrome were related to nutrient intake which requires a national level of lifestyle intervention for the prevention and management of metabolic syndrome.

The purpose of this study is to provide basic data for resolving individual and regional health inequalities by identifying factors that affect healthy living practices, and to protect the access to health equity and the access to health equity and the people's right to health. Raw data from the 2019 Community Health Survey were used, and descriptive statistical analysis and multivariate logistic regression analysis were performed using SAS 9.4 and IBM SPSS ver. 21. The healthy living practice rate was 33.8% overall, and there was a difference of 11~20% by region. In terms of individual factors, healthy living practices were significantly different in gender, age, occupation, sleep time, subjective health status, and subjective stress level. In the interpersonal factor, there was a difference in social activity for healthy living practice, and in the community factor, positive attitude toward the local physical environment, annual unsatisfied medical care, and use of health institutions were significant. In order to increase the practice of healthy living by region based on the research results, comprehensive policies and cooperative measures that can be approached at the individual, social and national level should be implemented along with specific strategies.

Due to the rapid increase of the elderly population in Korea, there is a growing interest in 'Healthy Aging.' In this trend, it is important to identify the relationship between their lifestyle factors and quality of life. The purpose of this study was to identify the association of physical activity level, sedentary behavior and health-related quality of life (HRQoL) among Korean older adults. A total of 4,589 older adults at the Sixth and Seventh National Health and Nutrition Examination Survey was analyzed. The results showed that better HRQoL was observed among physically active older female, which was more evident among physically active female with central obesity while no such relationship was observed among older male. On the other hand, higher sedentary time was associated with lower HRQoL in both male and female subjects. Our analyses indicated that central obesity was closely related with HRQoL regardless of their physical activity levels in female subjects. Further analyses investigating association between sub-dimension of HRQoL and sub-domain of physical activity showed that higher transport physical activity was associated with better anxiety/depression score and higher sedentary time was associated with poorer score on mobility, usual activities among male and mobility, self-care, usual activity and anxiety/depression among female. Our finding suggests that physical activity level, sedentary behavior and central obesity associated with HRQoL.
