Objectives: The present study aimed to analyze the factors that could affect the health-promoting behaviors of North Korean adolescent refugees residing in South Korea. Methods: Questions about their sociodemographic variables, subjective health status, healthy living habits, and health-promoting behaviors were asked. Results: Statistically significant differences were found in religion (t=2.30, p<0.05), having family members in South Korea (t=2.02, p<0.05), and subjective health status (t=4.96, p<0.01). Scores on health-responsible behaviors were higher with higher age (t=2.90, p<0.01) and for subjects without family or friends (t=2.43, p<0.05). Higher physical-activity behaviors were observed in males (t=3.32, p<0.01), in those with better subjective health status (t=3.46, p<0.05) and lower body mas index (t=3.48, p<0.05), and in smokers (t=3.17, p<0.01). Nutritional behaviors were higher in those who followed a religion (t=2.17, p<0.05). Spiritual growth behaviors were higher in those who followed a religion (t=4.21, p<0.001), had no family in South Korea (t=2.04, p<0.05), and had higher subjective health status (t=5.74, p<0.01). Scores on interpersonal relationships and stress-management behaviors were higher for those with higher subjective health status. A multiple regression analysis showed greater effects on health-promoting behaviors when subjective health status was better. Older people and non-smokers exhibited more health-responsible behaviors, while more physical-activity behaviors and spiritual growth activities were observed when subjective health status was better. Interpersonal relationship behaviors had positive effects on those with good subjective heath status and on non-smokers. Conclusions: Based on the results of the current study, an alternative was suggested for promoting health in North Korean adolescent refugees.

Objectives : This study aimed to verify the association between wealth or income level and health status after adjusting for other socio-economic position (SEP) indicators among Korean adults aged 45 and over. Methods : Data were obtained from the 1st wave of Korean Longitudinal Study of Ageing (households: 6,171, persons: 10,254). We used self-rated health status and activities of daily living (ADLs) as dependent variables. Explanatory variables included both net wealth measured by savings, immovables, the other valuated assets and total income including pay, transfer, property and so on. Binary logistic regression was conducted to examine the relationships. Also, in order to determine the relative health inequality across economic groups, we estimated the relative index of inequality (RII). Results : The inequality of health status was evident among various wealth and income groups. The wealthiest group (5th quintile) was much healthier than the poorest group, and this differential increased with age. Likewise, higher income was associated with better health status among the elderly. However, these effects, as measured by the odds ratio and RII, showed that wealth was more important in determining health status of elderly people. Conclusions : This study suggests that economic capability plays a significant role in determining the health status and other health-related problems among the elderly. Particularly, our results show that health status of the aged is related more closely to the individual s wealth than income.

Research on social hierarchy is a growing research topic in the studies of management and organization. Despite the abundance of studies demonstrating the relevance of social hierarchy in teams, little understanding exists for status disagreement among team members, specifically how status disagreement reduces team members' contributions to influence team performance. This conceptual study argues that team status disagreement negatively impacts team performance through reduced team member's knowledge contribution, including reduced team knowledge sharing and increased knowledge hiding. In addition, we propose that team skill differentiation aggravates the negative effect of status disagreement, such that when team skill differentiation is high, teams under high status disagreement are more likely to experience detracted team performance. This research mainly discusses status disagreement and its effect on team knowledge contributions by reviewing previous literature and developing several propositions, suggests theoretical contributions and practical implications, and presents an agenda for future research.

This study investigated and tested the overall level of dietary habits and health status/health management of the residents in a rural area. The interview survey was performed in March 2004 with a structured questionnaire to 510 residents who lived in Muan-Gun of Jeonnam province. The questionnaire was the abridged Scale of Dietary Habits and Health Status which surveys the morbidity, subjective health status, health management, and health examination. The Chi-squire method was used for some of the cross-sectional data. The 510 adult respondents were composed of 61.2% male and 38.3% female. In regularity of meal time, 56.3% of the subjects had a meal regularly(eating time), while 73.5% had a balanced diet(eating number). The habit of regular meal time was significantly higher in old people than in young people. The majority of the subjects had an appropriate meal amount. Unbalanced diet was higher in young people than in old people. 51.4% had the dining out and was significantly higher in younger people than in old people. In other questions, 60.7% of the subjects took a snack, 77.3% were under regular health management, and 49.6% had health examination. A minority of the respondents (31.3%) had disease, while 13.5% chronic disease, and 17.8% had acute disease. The level of dietary habits and general characteristics were positively correlated with each other, as were habits and health status. These results suggest the need for nutritional education programs directed at young people with a special emphasis on regularity of meal time. unbalanced diet, dining-out and a snack.

Purpose: This study investigated the health status and health management program of 119 emergency medical technicians (EMTs). Methods: A self-reported questionnaire was completed by 794 EMTs in two cities from November 15 to December 20, 2016. The questionnaire collected the general characteristics of the subjects (10 items) and health-related information from 119 EMTs (14 items). Data were analyzed by using SPSS 23.0. Results: The mean value for the general health status of the 119 EMTs was 2.68. The general health status was lower for female 119 EMTs, older 119 EMTs, and married 119 EMTs; it was higher for 119 EMTs with more than 5 years of experience and for 119 EMTs with diseases. The mean value for work-related fatigue of the 119 EMTs was 3.26. This value was higher for female 119 EMTs (p<.05). 119 EMTs with more than 2 years of experience, and 119 EMTs with diseases (p<.01). The correlation between health program participation and general health status was significantly positive (r=.271), whereas the correlation between health program participation and work-related fatigue was significantly negative (r=-.375). The correlation between health program participation and program satisfaction was significantly positive (r=-.770). Conclusion: It is important to develop health management program for 119 EMTs and to offer them at all times.

Blast furnace revamping in steel industry is one of the most important work to complete the complicated equipment within a short period of time based on the interfaces of various types of work. P company has planned to build a Smart Tracking System based on the wireless tag system with the aim of complying with the construction period and reducing costs, ahead of the revamping of blast furnace scheduled for construction in February next year. It combines the detailed design data with the wireless recognition technology to grasp the stage status of design, storage and installation. Then, it graphically displays the location information of each member in relation to the plan and the actual status in connection with Building Information Modeling (BIM) 4D Simulation. QR Code is used as a wireless tag in order to check the receiving status of core equipment considering the characteristics of each item. Then, DB in server system is built, status information is input. By implementing BIM 4D Simulation data using DELMIA, the information on location and status is provided. As a feature of the S/W function, a function for confirming the items will be added to the cellular phone screen in order to improve the accuracy of tagging of the items. Accuracy also increases by simultaneous processing of storage and location tagging. The most significant effect of building this system is to minimize errors in construction by preventing erroneous operation of members. This system will be very useful for overall project management because the information about the position and progress of each critical item can be visualized in real time. It could be eventually lead to cost reduction of project management.
