This study examined the effects of the economic activity status on the mental health of middle and older adults. In terms of mental health, a theoretical model was used to evaluate the mediating role of the income level and the satisfaction in family relationship. Using data from Korean Longitudinal Study of Ageing, job seekers and those who had never worked before were excluded and employees and retirees (over 45 years old) who have both a spouse and children were selected for the analysis. The variables were the economic activity status, the income level, the satisfaction in family relationship, and the mental health. The results show that the number of employed middle and older adults were higher than that of retirees, and the satisfaction in family relationship were generally high. In terms of mental health, the level of happiness was high, while the level of depression was low. Also, the pathway analysis of the effect of the economic activity status on the mental health shows that the economic activity status directly affects the mental health and gives indirect effects through the medium of the income level and the satisfaction in family relationship.

Given the increasing importance of entrepreneurship in a nation's economic growth, this study empirically examined the effect of entrepreneurial behavior and environment on economic growth based on country level data. While previous studies have centered on entrepreneurship as a dominant variable that impacts economic growth, this study has extends the discussion by empirically testing the effects of two entrepreneurial variables, which are entrepreneurial behavior and entrepreneurial environment, on economic growth. Furthermore, the study attempted to examine the moderating effects of trade and innovation on the relation between the independent variables and economic growth. According to the panel analysis using data from GEM and World Bank, both entrepreneurial behavior and environment affected national economic growth, completely or partly. Results showed that opportunity-driven entrepreneurial behavior has a significant effect on economic growth, suggesting that qualitative aspect of entrepreneurial activities are critical to economic growth. The results also indicated that both trade and innovation have significant moderating effects on the relationship between governmental support program and economic growth.

The present study aimed to investigate the rate of unmet healthcare needs for elderly over the age of 65 years, as well as analyze the relevance between employment status and unmet healthcare needs due to financial reasons. With regard to the study method, a logistic regression analysis was performed to investigate the correlation between employment status and unmet healthcare needs due to financial reasons, targeting 5,528 subjects over the age of 65 years. The results showed that the rate of unmet healthcare needs was 18.9%, in which the rate of unmet healthcare needs due to financial reason was 8.1%. The rate of unmet health needs was higher for temporary workers(ORs=1.75) than for retirement workers. However, the rate of unmet healthcare needs caused by financial reasons was higher among day workers(ORs=1.92). In conclusion, in order to prevent unmet healthcare needs for senior Korean patients, it is necessary to not only improve the income security system for the elderly, but also improve the occupational form and level of income of these economically active citizens, considering the increase in average life expectancy. Moreover, it is also necessary to reinforce health insurance coverage systems for settling medical expenses.

A survey was conducted of the total of 57 adults with disabilities from 60 years old to more than 20 years old residing in Jeju Island in which they were interviewed three times in May 2015. Supplementary data was provided by one of the male adults with disability who acts as a lecturer and helped to improve our awareness of the disabilities. The following conclusions were drawn from this research: First, as regards the effect of the economic activity of the disabled on their self-efficacy, their economic activity does not have any significant effect on their self-regulating efficacy and task difficulty preference, but does have an effect on their self-confidence. Third, according to the $Scheff{\acute{e}}$ verification on the differences in the self-efficacy of the disabled depending on their economic activity, employment (M=23.48, p<.04) and lecturer activities (M=22.06, p<.04) (had a greater effect?) than unemployment (M=18.93, p=<.04) but no difference between their employment and lecturer activities was found.

The purpose of this paper is to study the effect of the corporate social responsibility by port operation organization on the brand asset, reputation and relationship performance perceived by interested parties. To achieve such a purpose, literature survey on various research papers and thesis, research report is carried out and also reliability analysis, validity test and multiple regression analysis using SPSS 18.0 are used. To verify a established research model for empirical analysis and hypotheses, questionnaires are distributed to the port operation organization, terminal operators, shipping companies and NGO. Total 414 copies of questionnaires were collected and used in this analysis. The main results of the study are summarized as below. First, it was confirmed that social responsibility of the port operation organization are classified into three categories; economic, legal, and charitable and ethical responsibility. Second, economic responsibility has a positive impact on the brand awareness and reputation. Third, legal responsibility has a positive impact on the trust and commitment. Fourth, charitable and ethical responsibility has a positive impact on brand image and awareness, reputation, trust and commitment. Further additional empirical research can be extended by distributing more questionnaires including several port operation organizations in Busan and Incheon.

This study examined whether relationship marketing activities affected relationship satisfaction and ultimately relationship continuity intention for 180 online store users. As a result of hypothesis test through path analysis, it was found that financial activities and structural activities such as delivery services in shopping malls had a positive effect on relationship satisfaction. In particular, it was found that the influence of structural activities was greater. This suggests that fast delivery or easy-to-search traffic is more meaningful to relationship satisfaction than economic benefits. At the significance level p<0.05, it was found that social activities did not have a significant effect on relationship satisfaction. Because it is not easy to develop social bonds between salespeople and customers at online stores, but the direction is considered positive. Therefore, if online stores can form social bonds with customers, this will have a positive effect on relationship satisfaction, but it is expected that this will become a factor that can differentiate them from competitors.

This study is an empirical study on the effect of eco-friendly management activities of small and medium-sized manufacturers on job improvement. The summary of the analysis results is as follows. first. Among the eco-friendly management activities of SMEs, it was analyzed that social activities did not have a statistically significant effect on job improvement, and second. Environmental activities were found to have a significant effect on work productivity with 𝛽= .394 (p<.001), and job satisfaction showed a low causal relationship with 𝛽=.216, p<.05, and third. Economic management activities were found to have a significant effect on job satisfaction, with 𝛽= .388 (p<.001). In addition, a low causal relationship was confirmed with 𝛽= .267 (p<.01) in work productivity. Therefore, among the effects on job improvement, it was found that environmental activities affect job productivity and economic management activities affect job satisfaction. This study is meaningful in creating an environment for SMEs' eco-friendly management activities, presenting competitive strategic directions, and providing basic data for research.

Competing risk analysis is widely applied to analyze a failure time with more than two causes. This paper discusses the application of a competing risk model to a economic activity state of workers with occupational injuries. In particular, main interest is to estimate the distribution of restarting time two kinds of economic activities, (i) returning to original working place and (ii) finding a new job. In this paper, we applied a cumulative incidence function to evaluate their patterns under several individual factors and working place's factor. Furthermore, a subdistributional regression model is applied to estimate the effect of these factors on the returning time. According to result, worker with higher education, younger age and longer working period had a higher chance to return an original working place while one with more severe injuries and skilled laborer had longer returning time to an original working place.

I develop a matching model in which risk-averse workers face borrowing constraints and make a labor force participation decision as well as a job search decision. A sharp distinction between unemployment and out of the labor force is made: those who look for work for a certain period but find no job are classified as the unemployed and those who do not look for work are classified as those out of the labor force. In the model, the job search decision consists of two steps. First, each individual who is not working obtains information about employment opportunities. Second, each individual who decides to search has to take costly actions to find a job. Since individuals differ with respect to asset holdings, they have different reservation job-finding probabilities at which an individual is indifferent between searching and not searching. Individuals, who have large asset holdings and thereby are less likely to participate in the labor market, have high reservation job-finding probability, and they are less likely to search if they have less quality of information. In other words, if individuals with large asset holdings search for job, they must have very high quality of information and face very high actual job-finding probability. On the other hand, individuals with small asset holdings have low reservation job-finding probability and they are likely to search for less quality of information. They face very low actual job-finding probability and seem to remain unemployed for a long time. Therefore, differences in the quality of information explain heterogeneous job search decisions among individuals as well as higher job finding probability for those who reenter the labor market than for those who remain in the labor force. The effect of the extended maximum duration of unemployment insurance benefits on the aggregate labor market and the labor market flows is investigated. The benchmark benefit duration is set to three months. As maximum benefit duration is extended up to six months, the employment-population ratio decreases while the unemployment rate increases because individuals who are eligible for benefits have strong incentives to remain unemployed and decide to search even if they obtain less quality of information, which leads to low job-finding probability and then high unemployment rate. Then, the vacancy-unemployment ratio decreases and, in turn, the job-finding probability for both the unemployed and those out of the labor force decrease. Finally, the outflow from nonparticipation decreases with benefit duration because the equilibrium job-finding probability decreases. As the job-finding probability decreases, those who are out of the labor force are less likely to search for the same quality of information. I also consider the matching model with two states of employment and unemployment. Compared to the results of the two-state model, the simulated effects of changes in benefit duration on the aggregate labor market and the labor market flows are quite large and significant.
