The purpose of this study was to examine the impact of the social maturity of sustained sport-for-all participants on their physical and mental health. The subjects in this study were 190 company employees who were selected by convenience sampling from among the residents in Gangwon Province. The selected office workers continued to participate in sport-for-all programs. After a survey was conduced from November 7 to 25, 2011, the statistical package SPSS WIN 18.0 was employed to analyze the collected data. To find out the general characteristics of the subjects, frequency analysis was made, and the reliability test of the instrument and factor analysis were carried out. Descriptive statistics analysis was made by factor, and multiple regression analysis was utilized to look for connections among their variables. As a result, it's found that the social maturity of the sustained sport-for-all participants made a significant difference to their physical health, and that their social maturity made a significant difference to mental health as well. As sustained sport-for-all participation was found to be correlated to their physical and mental health, office workers should be given a chance to participate in sport-for-all on a long-term basis.

The study measured a subway construction worker's Macpa stress by Heart Rate Variability measuring instrument and conducted a survey of Korean job stress from subway construction workers. Also, the study analyzed the relationship between Macpa stress index and Korean job stress result and suggested managing stress method for each item. According to National Statistical Office data, the first line subway in Seoul was started to open in 1974. The extended total length is 996 kilometers until 2019. Many aged workers are currently working at subway construction sites due to the avoidance of young workers since the past until now. It means that the elderly has a substantial portion among subway construction workers. The productivity has been adversely affected by health problems due to the aging of workers, job stress due to heavy work, and personal health problems. So, the regulation and policies on job stress health management are being strengthened. The data were measured Macpa stress by machine measuring heart rate variability and conducted Korean job stress survey(shortened) from Sa-sang to Ha-dan line Busan subway construction workers for analyzing the relationship. Independent variable were age, job duration, job position, employment type, working type in this study. Macpa's dependent variable was stress index and Korean job stress survey(shortened)'s dependent variables were job requirements, job autonomy, relationship conflict, job instability, organizational structure, inappropriate compensation, working place culture, and total score. SPSS 12.0 K Statistics Program was used for statistical analysis. Kruskal-wallis test, a nonparametric statistical analysis, was used because the data are difficult to be assumed as normal distribution. As a result, the paper indicated the significant correlation between Macpa stress index and Korean job stress(short version). The elderly workers presented higher Macpa index and higher job stress due to aging and heavy-duty work. The majority workers were daily workers who had unstable working condition and uncertainty about the future. The study suggested a manual that could reduce job stress for subway construction workers and future study deriving management tool through analyzing job stress factor is necessary.

This study compares the difference of fit factors (FF) and visual acuity according to masks and eyeglasses preferences for 54 participants. We the precautions and behaviors of discomfort when wearing masks of eyewear wearers. Contact lens discomfort and priority action of complaints was investigated Glasses fitting factors is Optical Center Height(OH), Vertex Distance(VD) and Pantoscopic Angle(PA). We measured those factors and expressed by the ratio of standard point and change point. Quantitative fit factor was measured by Portacount Pro+ 8038. Also, we selected to 6 exercises among 8 exercises OSHA QNFT (Quantitative Fit testing) protocol to measure the fit factors. The pass/ fail criterion of FF was set at 100. Visual acuity(VA) test chart is developed by Chunsuk Han was used, Descriptive statistics was performed. Descriptive statistics(SAS ver 9.2), it is used geometric means, Wilcoxon analysis(P=0.05) When wearing the mask preferentially, fit factor(FF) was high according to the step of glasses fitting parameter. on the other hand, when the glasses first choice, the visual acuity(VA) was high. there was no significant difference. In the case of fit factor (FF), mask first choice/ glasses first choice is OH (p=0.671/ p=0.332), VD (p=0.602/ p=0.571) and PA (p=0.549/ p=0.607). Visual acuity (VA), mask first choice/ glasses first choice is OH (p=0.753/ p=0.386), VD (p=0.815/ p=0.557) and PA (p=0.856/ p=0.562). The workers of workplace and office chose glasses but occupational health workers and students chose mask. In case of discomforts, it was suggested to remove the mask and tolerate discomforts. The main discomforts and usual action of lens were dryness, hyperemia, foreign body sensation, ophthalmodynia, decreased vision and glasses wearing. Therefore, it is necessary to develop a mask wearing method education program considering glasses fitting and develop a hybrid model that minimizes inconvenience when wearing glasses and a mask at the same time.

To examine the key success factors for long-lasting restaurants, we visited 10 restaurants with 30 or more than 30 years of tradition, located in Seoul and Gyeonggi-do districts, to research these restaurant menus and customer characteristics by observation and interview. The results were analyzed using descriptive statistics. The outstanding feature noted was that each and every restaurant had its own simple and specialized menu. We found that this feature created a virtuous circle that reinforced itself through a positive feedback loop. The simple and specialized menu increased both the cooking efficiency and food quality while it reduced both food and labor costs, this enabled the customers to eat at an affordable price and have generous servings. This lead to customer satisfaction and revisits to the restaurant, which triggered word-of-mouth referral and expansion of their customer base. This in turn created higher operating profit margins that could be reinvested in the business. The secret recipes for cooking, invented by their founders, were passed on from generation to generation. Their customer base included customers of all ages from children to senior people. And their regular customers consisted of neighboring office workers and families traveling from a long distance. We hope that our findings on long-lasting restaurants, especially of the virtuous cycle created due to the simple and specialized menus with secret recipes, will contribute to the development of Korean style long-lasting restaurant model.

This study measures the relationship between labor productivity and national competitiveness. Through the shift- share analysis method, the paper has separated labor productivity into three factors: static shift effect, dynamic shift effect and endogeneous effect. Next, in combination with the Granger causality test, the paper examines the relationship between the factors constituting labor productivity and competitiveness during the period from 2005 to 2017. Research data is collected from General Statistics Office and annual global competitiveness reports. The results show that the interaction between labor productivity with global competitiveness index (GCI) in Vietnam has similar variation. Nevertheless, when separating labor productivity into three effects, this relationship shows more clearly that the impact of labor productivity on GCI scores is mainly caused by endogeneous effect, not by static shift effect or dynamic shift effect. Therefore, in order to improve its competitiveness, Vietnam should focus on a number of solutions: reforming the education system towards developing thinking capacity and creative capacity; fostering industrial manners to create dynamic and flexible workers; building the State with sufficient capacity to implement consistent and transparent policies; formulating policies to attract all economic sectors so that they actively participate in the field of human resource training for the country.

Objectives: The purpose of this study was to identify the health promotion activities of the elderly Korean aged 65 or older and to examine the related factors associated with the health promotion activities. Methods: Data were obtained from 2008 Social Statistics Survey of Korea National Statistical Office of 6,207 people aged 65 or older. We measured the socio-demographic characteristics, physical health status, social health status, and health promotion activities. Statistical analyses were employed through the $X^2$-test and Odds ratio using Logit Model. Results: In our study, health promotion activity practice rates were varied among the socio-demographic characteristics, physical and social health status. Our findings also support that better socio-demographic and physical health status explain the higher practice rates of health promotion activities. In addition, the higher social health status was associated with better practice rates of health promotion activities. Conclusion: We found that the health promotion activities of the elderly could be encouraged by better socio-demographic status and physical and social health status. To better accomplish the health promotion for the elderly in our community, policy-makers should need careful political deliberation for executing health promotion services considering the distinctions of programme and target groups.

Modern society has become an aging society, and the National Statistics Office(NSO) expects that Korea will be also an aging society by 2019, that is, people over the age of 65 will account for 14 percent from the total population. In addition, the increase of labor flexibility is also one of the dramatic features in modern society. However, this social shift have unpredictable results, that is, the advent and increase of grandparent and grandchildren family. Modern medical technology has given Koreans longer expectancies, and structural and economic changes in society have brought early retirement. One of the main reasons that grandparent and grandchildren family increase is below an average of two children per family. There are various services available such as Health support center, Dream start center, Youth support center, Community child center, and Community welfare center. Besides, schools operates various programs for grandparent and grandchildren family with social workers and school counselors. But, most of all, what is necessary is a change of perspective on them. Basically, we need to develop a clear perspective on grandparent and grandchildren family as a not dismantling family type but alternative family type with creating a separate program or service
