The purpose of this study is to examine the importance of entrepreneurs' well-being, and to propose several ways to improve it. First, the factors influencing entrepreneurs' well-being were explored via previous literature review, and positive psychological capital based on positive psychology was selected as the main factor. In addition, the hypotheses were formulated and the research model was constructed by selecting authentic leadership, mastery goal orientation, and social support as the antecedents predictably associated with positive psychological capital. To empirically analyze the proposed model, a questionnaire survey was conducted for the entrepreneurs who fulfilled the training/coaching/consulting programs offered by the Youth Startup Academy. By using the collected 133 responses, PLS-Structural Equation Analysis, PLS-Multi Group Analysis(MGA), and PLS-Importance-Performance Map Analysis(IPMA) were performed. As a result, it was found that positive psychological capital had a high causal relationship with the well-being of entrepreneurs; and authentic leadership and mastery goal orientation had a positive effect on positive psychological capital. However, the statistical significance of the impact of social support has not been verified. While differences in causality between early and growing stages of start-ups only acted as sub-factors of positive psychological capital, the aforementioned three antecedents showed a significant difference for hope and optimism, respectively. This study expanded the topic of entrepreneurship-related research, which mostly focuses on identifying the performance factors of start-ups. It is meaningful in that it empirically verified the causality model constructed by exploring the factors with respect to the mental well-being of entrepreneurs, which is a main theme in the entrepreneurship-related research. These results found in the current study will render practical insights to entrepreneurs, researchers, and educators.

The Northern States of Malaysia comprises of four states (Penang, Kedah, Perlis and Perak) still record high poverty incidence eventhough Malaysia has experienced a remarkable reduction of poverty over the past century. Economic activities in Perlis and Kedah that are predominantly agriculture in the rural area contribute to this disparity. To add, rural households are also subject to risks and uncertainties that make them more vulnerable to poverty. This study examines the impact of risks and assets on households' vulnerability to poverty. A survey of 400 respondents was conducted in December 2015 in the northern region of Malaysia. From these 400 questionnaires, only 298 were considered valid and used in the analysis. Using a logistic probability function, the results indicated that risks are not a significant threat to households. Gender and strata are crucial elements that significantly determine households' vulnerability. While human capital and financial capital significantly reduce households' vulnerability to poverty, physical and natural capitals were not statistically significant. The study suggests that the government and practitioners design strategies and policies with an assets-based approach. The asset-based approach is more appropriate for linking the causes of poverty to vulnerability.

The use of school should not be limited to student education any longer but be extended for attaining social benefits. For this reason, school should play central roles not only in education but also in childcare, welfare, culture, physical education, etc. In order for school to accommodate various new functions, it is essential to promote the mixed-uses of school facilities, and this process requires the involvement of private capitals for early achievement of social benefits from school facilities. Thus, this study purposed to examine the necessity of the multiple uses of school facilities through the investment of private capitals, to diagnose the adequacy of build-transfer-lease (BTL) applied currently to the multiple uses of school facilities, and to find obstacles to the activation of private sector investment and suggest solutions for the obstacles. In particular, this study aimed at proposing plans to enhance the efficiency of private sector investment and activate private sector investment projects by suggesting how to promote the multiple uses of school facilities in consideration of profitability for private investors.

This study analyzed the factors affecting the reemployment intention of the baby boomer. To this end, an extended Model of Goal-directed Behaviors(MGB) was set as a research model. The extended MGB used in this study added economic readiness and social capital to attitudes, subjective norms, positive anticipated emotions, and perceived behavioral control variables as independent variables. The desires was set as a mediating and the reemployment intention was set as the dependent variable. The research model was empirically analyzed with 201 baby boomers. Empirical analysis showed that economic preparation had a negative effect on reemployment intention, and social capital had a positive effect on reemployment intention. Economic preparation rather than social capital was found to have a stronger impact on the intention of reemployment. Attitudes, subjective norms, positive anticipated emotions, and perceived behavioral control variables were not tested for a significant direct effect on reemployment intention. They were found to have a significant influence on reemployment intention through the mediating of desires. Based on the results of this empirical analysis, academic and practical implications were presented.

This study is about entrepreneurial intention of baby boomers who started retirement, starting with the second phase of life. A research model was constructed focusing on factors that will affect the entrepreneurial intention of baby boomers. In order to test the study model, a questionnaire was surveyed on baby boomers, and among them, 204 people, which was valid, was used for analysis. The hypothesis test was a structural equation model using the AMOS 23 statistical package. As a result of the hypothesis test, self-efficacy and social capital had a positive (+) relationship with entrepreneurial intention. Economic preparation was found to have a significant negative (-) relationship with entrepreneurial intention. Social capital was found to have the most influence on baby boomers' entrepreneurial intention. On the other hand, achievement experience and role model learning experience were the antecedent variables affecting self-efficacy. As a result of testing their relationship, achievement experience and role model learning experience had a significant positive (+) influence on self-efficacy. Based on the research results, academic and practical implications were presented.

This study aimed to construct and test a hypothetical model to explain health-promoting behaviors among high school students in Korea. Data were collected from a self-administered questionnaire of 395 first-year to third-year students at a high school in Gyeonggi-do area. The exogenous variables of this study were family function, friend support, school life environment, and social capital of the local community, and endogenous variables were self-efficacy, self-regulation, and health-promoting behaviors. Data were analyzed by SPSS 21.0 and AMOS 22.0. The final model with 13 of the 9 analyzed paths showed a good fit to the empirical data: χ²/df=1.96, GFI=.90, AGFI=.88, CFI=.94, TLI=.93, RMSEA=.05, SRMR=.06. The variables included in these paths were family function (β=.57), self-efficacy (β=.29), self-regulation(β=.14), the social capital of local community (β=.14), and friend support (β=.13). The variables included in the nine significant paths explained 86% of variance in the explain model. Thus, it is necessary to build up a social support system for dysfunctional families and health-promoting behaviors of adolescents in the families and develop a program for creating the environment of the local community including schools.

Underground infrastructure systems provide essential public services and goods through buried structures including water and sewer, gas and petroleum, power and communication pipelines. The majority of existing underground infrastructure systems was installed in green field areas prior to development of complex urban built environments. Currently, there is a global trend to escalate major demand for underground infrastructure system renewal and new installation while minimizing disruption and maintaining functions of existing superstructures. Therefore, Engineers and utility owners are rigorously seeking technologies that minimize environmental, social, and economic impact during the renewal and installation process. Trenchless technologies have proven to be socially less disruptive, more environmentally friendly, energy conservative and economically viable alternative methods. All of those benefits are adequate to enhance overall sustainability. This paper describes effective sustainable solutions using trenchless technologies. Sustainability is assessed by a comparison between conventional open cut and trenchless technology methods. Sustainability analysis is based on a broad perspective combining the three main aspects of sustainability: economic; environmental; and social. Economic includes construction cost, benefit, and social cost analysis. Environmental includes emission estimation and environmental quality impact study. Social includes various social impacts on an urban area. This paper summarizes sustainable trenchless technology solutions and presents a sustainable construction method selection process in a proposed framework to be used in urban underground infrastructure capital improvement projects.
