This study was carried out to evaluate Korean eating behavior which is highly correlated with their nutritional status, and to analyze the effect of various factors on eating behavior. The above information was used to develop a nutritional status for Korea. The 2000 Korean people were selected with the stratified random sampling method. This study used a questionaire as instrument tool. The questionaire consists of :1) socio-demographic characteristics of the subjects; 2) the valuation of food and nutrition; 3) the concern of food and nutrition; 4) psychological health condition; 5) physical health condition; 6) nutrient consumption status and 7) analysis of eating behavior. Data were analyzed by using a SPSS PC Package. Significant differences and correlation among variables were determined by the t-test, $x^2-test$, ANOVA, pearson's correlation coefficient and Multiple regression analysis. The results of this study can be summarized as follow, All nutrient intakes were significantly correlated with eating behavior score(p<0.001). Factors such as socio-economic status, valuation and concern on food and nutrition, and psychological health condition had significant relationship with eating behavior. But the physical health condition had no significant effect on it. Multiple regression analysis showed that valuation of food and nutrition made the greatest contribution(35.6% explained) and concern made the second greatest contribution(10.5% explained). The third was education level(9.8% explained), and the forth psychological health condition(1.8% explained).

The purpose of this study was to investigate the mediating effects of parental neglect on the relationship between family environment, such as economic status and harmony of family and contact with harmful environments. The data came from the 2009 Korean Survey on the Rights of Youth (N = 6,601). The data was analyzed using Structural Equation Modeling by means of SPSS 17.0 and AMOS 7.0. Bootstrap method used to test significant mediating effects. We found that family environment influences an adolescent's contact with harmful environments through parental neglect, showing that family environment has both indirect and direct effects. The results suggested that a family with low socio-economic status and more stress than harmony engenders a negative effect on the behavior of parents providing care and affection. This neglect influences the adolescent's contact with harmful environments such as harmful media and facilities. It must be acknowledged that parental care and suitable affection play a minimal role in adolescent's contact with harmful environments.

Background: This study purposed to compare the difference on medical utilization and health expenditure of baby boomer generation by depression between gender. Methods: Korea Welfare Panel Survey 2016, provided by the Korea Institute for Health and Social Affairs, was used for the analysis. For the research, we used the two-part model, yes or no of use (part 1), and frequency of use (part 2) for medical utilization. The dependent variables are the whether or not to use of hospitalization services, outpatient services, length of stay, outpatient service visits, and health expenditure. And the independent variables are used as the predisposing (education, spouse presence), enabling (insurance type, private insurance, economic activity, income), and need (chronic disease, self-rated health, disability) factors in the Andersen behavior model. Depression was used as intervening variables. Structural equation model and multiple group analysis by gender were used. Results: There were differences in the medical care usage and cost between men and women in baby boomer. For men, mediating effects of depression were present at the hospitalization (yes/no), length of stay, and health expenditure. On the other hand, for women, the mediating effect of depression was found only at the outpatient visits. Specially, depression was working at the medical services by the different way between gender. The size of effect (multiple group analysis) was affected by significant differences between men and women. Conclusion: This study found that the mediating effect of depression is increased medical usage and health expenditure and the effect factors are different by gender. Therefore, it is necessary to establish a medical care policy considering the socio-economic characteristics of baby boomers.

Recently, the Ministry of Strategy and Finance announced a plan to reduce the proportion of economic evaluation in non-metropolitan areas and strengthen balanced development evaluation through the reorganization of the preliminary feasibility study system. In addition, the social value of the quality of life, such as job, environment, and safety, which may be affected by the implementation of transportation facility investment projects, was reflected as the main item of policy evaluation. In this study, the ripple effect of the project in terms of social value was reviewed for the Gangil-Chuncheon. The effect of highway opening was investigated by reviewing the feasibility report, post-evaluation report, and statistical indicators. Recently, the Gangil-Chuncheon highway is getting used by around 110,000 people per day. The number of tourists in Chuncheon rapidly has increased from 5 million a year to more than 11 million now. In addition, it was confirmed to produce effects such as population migration, net inflow and land price increase, improvement of living convenience, and expansion of emergency medical care. Although this ripple effect was influenced by various socio-economic factors as well as the opening of the highway, it is clear that it is difficult to occur without the opening of the highway. It is judged that the evaluation of indirect benefits and social values due to the opening of the highway can be quantified through continuous research and data construction. Post-evaluation of construction works, including project efficiency evaluation and ripple effect evaluation, is performed for construction works with a construction cost of more than 50 billion won. In the future, we will continuously improve the evaluation system in order to evaluate the indirect benefits and social values of public investment projects.

Objectives: This research intended to examine the relationships among social capital, socioeconomic factors, and health-related lifestyles and the effect of these factors on self-rated health in the Republic of Korea. Methods: The data of the social statistics survey that the Korea National Statistical Office conducted in 2006 were chosen and 37,928 people from them, who were 25~59 years old were sampled. This paper made path analysis to examine the relationships among social capital, socioeconomic factors, and health-related lifestyle and the influence of these factors on self-rated health. Results: In relation to the overall influences of socioeconomic factors, social capital, and health-related lifestyle on self-rated health, the following factors had a significant positive direct effect: education(0.069), subjective class(0.108), marriage(0.054), satisfaction with family relationships(0.087), reliability of institutions(0.020), citizens' participation(0.021), exercise(0.037), and refrain from smoking(0.011). However, abstinence from alcohol(-0.067) had a negative direct effect on self-rated health Conclusion: Based on the results, this paper can suggest that the plan of keeping and building up social capital should be considered in the whole aspects of the society and the project promoting drinking moderation is required to consider social culture than individuals.

We have developed the Forest Carbon Sink Index on afforestation and reforestation activities, a regulation stated in article 26 of the 'Law on the maintenance and enhancement of carbon sink (Carbon Sink Law)', which took effect on March, 2013. According to the legal purpose to evaluate the performance of individual forest carbon offset projects and to compare each other at a certain point, values of the forest carbon sink index were calculated by the scoring method. Three criteria were established based on the Carbon Sink Law: 'Carbon' (real greenhouse gas reduction), 'Human' (socio-economic effect) and 'Nature' (environmental effect). Continuously, 9 indicators from the three criteria were selected by top-down approach; the adequacy of each criteria and indicators were reviewed through on-line Delphi survey; and finally weighted value of each criteria and indicators were assigned. To reflect the characteristics of the domestic forest carbon offset projects, which focus on corporate social responsibility-typed projects, we applied the score weighting method to minimize gaps among criteria and ones among indicators. After applying our newly developed forest carbon sink index to five domestic forest carbon offset projects, we could confirm that the criteria of 'Human' and 'Nature', which criteria are in relatively low weight, can play a role as an actual incentive to reduce negative socio-economic and environmental impacts. Based on performance evaluation of the five forest carbon offset project by the forest carbon sink index, the best or good performance project developers could be rewarded, and further the performance evaluation would work as an incentive to stimulate the involvement of domestic project developers in the field of forest carbon offset project.

Using the first wave of KLoSA(Korean Longitudinal Study of Ageing) beta version, this study analyzed factors affecting early retired men's subjective life satisfaction through Binary Logit and Multiple Regression. Total 552 men were selected as a sample. The main results of empirical analysis in this study were as follows: The retirement reason(health-) and monthly household income(+) affected whether they were satisfied with the retirement life or not and subjective life satisfaction over all. Especially, the retirement reason(health-) had a stronger effect on whether early retired min were satisfied with the retirement life or not and their subjective life satisfaction than monthly household income revealed significant variable in previous studies. This result represents that the retiree's life satisfaction analysis model must include retiree's characteristics at the time of retirement as well as retiree's current status characteristics or socio-economic characteristics.

The purpose of this study was to examine the effects of family strengths and self-esteem on depression among married women who have adolescents in middle and high school of their first child in Korea. To measure of depression using the CESD(the center for epidemiologic studies depression scale), the degree of husewives' depression was relatively higher than that of employed married women. As for the related variables, educational degree, S.E.S(socio-economic status), self-esteem turned out significant in housewives' depression. But, in the case of employed married women, these were not significant. Therefore, we are confirmed that the etiologic model of this study was more proper to housewives than employed married women. Finally, in both cases of housewives and employed married women, the effects of family strengths were mediated or moderated by self-esteem in predicting depression. The results of this study called for the encouraging of married women's self-esteem, the parti ipation of various social programs for housewives, and the programs to strengthening of their family relationships.

This evapaper is toluate the forecasting performance of three neural network(NN) approaches against ARIMA model using the famous time series analysis competition data. The first NN approach is to analyze the second Makridakis (M2) Competition Data using Multilayer Perceptron (MLP) that has been the most popular NN model in time series analysis. Since it is recently known that MLP suffers from bias/variance dilemma, two approaches are suggested in this study. The second approach adopts Cascade Correlation Network (CCN) that was suggested by Fahlman & Lebiere as an alternative to MLP. In the third approach, a time series is separated into two series using Noise Filtering Network (NFN) that utilizes autoassociative memory function of neural network. The forecasts in the decomposition analysis are the sum of two prediction values obtained from modeling each decomposed series, respectively. Among the three NN approaches, Decomposition Analysis shows the best forecasting performance on the M2 Competition Data, and is expected to be a promising tool in analyzing socio-economic time series data because it reduces the effect of noise or outliers that is an impediment to modeling the time series generating process.

The aim of this study is to measure the degrees of emotional labor and to empirically analyze how emotional labor affects individual's stress coping style and psychological burnout. The results were as follows. First, the call center employees were actually experiencing emotional labor and it was shown that the deep acting was higher than the surface acting. Second, the degree of experiencing stress coping style and psychological burnout appeared differently depending on the socio-economic variables of the employee. Third, despite the differences in the direction, there is a correlation between emotional labor, stress coping style, and psychological burnout. Fourth, the characteristics of the employees and emotional labor clearly affected stress coping style and psychological burnout. Therefore, companies will have to provide various psychological treatments and training programs for call center employees, and a change in social awareness, where people take the service industry workers' kindness for granted, is required as well.
