The purpose of this study is to analyze and assess the family policy of the Lee administration and to suggest agendas for sustainable future family policy. Traditionally, families are a unique unit of production and reproduction of family members and social laborers. In addition, families are the social safety net help people survive in a society. Therefore, family policies play an important role in contemporary society. In this context, we review the literature related to family and social policy, and the contents of Ministry for Health, Welfare and Family Affairs, which is the main authority in Korea. The results are as follow: Firstly, the Lee administration ignored the data showing that family policy should be a unique policy, and not a sub-division of welfare policy. Secondly, there is no difference between the active welfare policy of the Lee administration and policies of past administrations. Finally, this study suggests that subjects of future oriented family policy should focus on co-developing programs for the individual, family, and society, to develop problem-prevention and family needs- ordered policy, and to make integrated family policy through laws and delivery systems such as Healthy Family Centers.

The influencing factors of large-scale IT investment decisions are rarely investigated in an empirical perspective. We find out different behaviors in IT investment decisions according to the size of organization. Large scale IT-investment decisions (e.g. system downsizing) can be the outcome of decision-makers' motivation to adopt and control new IT systems- However, this phenomenon is salient in the large-sized organization rather than small-sized ones. Based on our investigation, we predict general IT decision-making behaviors in organizations when making IT investment decisions.

The rapid development of internet technologies and social media over the last few years has generated a huge amount of unstructured text data, which contains a great deal of valuable information and issues. Therefore, text mining-extracting meaningful information from unstructured text data-has gained attention from many researchers in various fields. Topic analysis is a text mining application that is used to determine the main issues in a large volume of text documents. However, it is difficult to identify related issues or meaningful insights as the number of issues derived through topic analysis is too large. Furthermore, traditional issue-clustering methods can only be performed based on the co-occurrence frequency of issue keywords in many documents. Therefore, an association between issues that have a low co-occurrence frequency cannot be recognized using traditional issue-clustering methods, even if those issues are strongly related in other perspectives. Therefore, in this research, a methodology to reorganize social issues from a research and development (R&D) perspective using social network analysis is proposed. Using an R&D perspective lexicon, issues that consistently share the same R&D keywords can be further identified through social network analysis. In this study, the R&D keywords that are associated with a particular issue imply the key technology elements that are needed to solve a particular issue. Issue clustering can then be performed based on the analysis results. Furthermore, the relationship between issues that share the same R&D keywords can be reorganized more systematically, by grouping them into clusters according to the R&D perspective lexicon. We expect that our methodology will contribute to establishing efficient R&D investment policies at the national level by enhancing the reusability of R&D knowledge, based on issue clustering using the R&D perspective lexicon. In addition, business companies could also utilize the results by aligning the R&D with their business strategy plans, to help companies develop innovative products and new technologies that sustain innovative business models.

ESG Investment is emerging as a trend and common sense in the financial market. ESG Investment is an investment method that simultaneously pursue social sustainability and investment returns from a long-term perspective by reflecting non-financial factors such as environment, society and governance in addition to corporate financial performance in investment decisions. This study checked how the characteristics of ESG investment have been changed after Covid-19. Afterwards, it was confirmed that Covid-19 actually acted as a negative factor in the securities market by applying VAR model. At the same time, it was demonstrated that ESG indices of the US and Korea outperformed their benchmark in terms of return and risk during the pandemic regime. The result of this study hints that the importance of ESG investment will be unchanged after Covid-19. At the same time, it suggests that managers should avoid passive ESG management and engage in strategic ESG management based on knowledge management.

Social enterprises that are solving pressing global issues and providing services such as micro-finance, affordable housing, appropriate technology and education for the 'bottom of the pyramid' as well as cultural and community-related businesses that improve the 'quality of life' within a society are the target of impact investments. Among them, a capital financing is one of the most important factor in founding and fostering of social enterprise. However, the capital market for social enterprises in South Korea are not yet sufficiently developed. The Britain and U.S.A. attempted to solve the social problem by the introduction of the social innovation credit model, for example, social impact bonds(SIB), Big Society Capital, DBLIF, and ACCION International, which are considered as an innovative new financing instrument for social program. Instruments are being attempted for the first time in Britain and America. This study have two purposes. The first purpose is abstracting the institutional mechanism for introduction of impact investment such as SIB and DBLIF case in Britain and U.S.A.. Second, analyzing type and mix of policy instrument on impact investment from the perspective of policy instrument.

As issues of education, employment and so on, the medical issue is one of the hot spots of society in China today. The health system reform which was pushed ahead after China's Revolution and open to the outside world hasn't received great progress. Many actual problems haven't been solved, for example it is difficult and expensive to see a doctor. With the development of the economy and society, the citizen's legal consciousness has gradually risen. They make a claim for better medical service. At the same time, the number of the disputes of medical care arises annually. China has sped up the opening of service trade for fulfilling promises of entry the WTO since 2001. China has already opened many service trade fields, including medical field. From the domestic perspective, there are many problems in domestic medical department. From the international perspective, China's present medical level falls behind the world advanced medical level. Under this background, it is a bold act for China to open the medical service field to foreign investors. Today, a huge medical service market is developed in China. However, the government's investment to medical devices and the financing channels is limited. Therefore, it is inevitable that individuals, social organizations and foreign investors invest to the medical market. In view of the situation, Chinese government issued a series of relevant laws and rules. In recent years, many multinational companies, consortiums, charitable institutions, enterprises and individuals establish various medical institutions in China. But there are rare research in the actuality and legal subject of foreign investment to Chinese medical market. Hence, it is necessary to realize the actuality of foreign investment to Chinese medical market, to familiar with the elements and procedure of establishing foreign joint and cooperative medical institution. Meanwhile, analyzing the existing problems and posing the legal subject have important theoretic and practical value.

The purpose of this study is to develop a business model that efficiently converts diesel power generation systems to renewable energy microgrids (MG) in large-scale islands. Most of the previous studies on the conversion of renewable energy MG in islands had limitations dealing with efficiency from the perspective of suppliers. However, the microgrid has the characteristic of getting benefits through the interaction between the consumer and the supplier. In addition, the efficient MG business model from the perspective of new institutional economics is a structure in which consumers and suppliers jointly participate. Therefore, this study assumed that the MG business model in which the supplier's MG and the consumer's community solar participated would benefit all participants, and verified the assumptions using domestic island data. In terms of supplier investment, the cost of power supply (LCOE) of assumed model was calculated to be 14.0% lower than that of the diesel model and 3.7% lower than that of the supplier-only MG model. From the perspective of consumer investment, electricity bills are expected to be reduced by more than 200,000 won per household per year through self-generation of solar power. Social benefits are expected to reduce external environmental costs. The CO₂ emissions of the assumed model were calculated to be 39.5% lower than the diesel model and 1.5% lower than the supplier-only MG model. Therefore, the MG business model with consumer participation proposed in this study is expected to be an efficient alternative to renewable energy MG conversion in domestic islands, and is meaningful as an energy plan that improves the benefits of local residents.

This study is an exploratory study on stock investment behaviors of individual investors in psychological perspective. The study is based on many behavioral finance studies which overconfidence of individual investors has an effect on irrational investment decision making and investment behaviors such as excessive trading. Accordingly, this study was to investigate the factors of self-enhancement perception on confidence of investment of individual investors and to find whether these psychological biases lead to irrational investment behaviors. The results indicated that there were sex differences in the factors of self-enhancement perception on individual investors' confidence of investment. In case of male investors, they were confident of their ability of investment but in case of female investors, they were confident of optimistic expectation of return. Also, male investors were more confident of investment than female investors. In addition, the result showed that risky investment behaviors of individual investors were influenced by psychological factors such as favorable self-evaluation, confidence of self-controllability, optimistic expectation of return and confidence of investment in part. This study suggests that further researches need to search after other variables which can mediate between psychological factors and investment behaviors of individual investors.

We analyzed the structures and properties of the global financial market networks using social network analysis approach. The Minimum Spanning Tree (MST) lengths and networks of the global financial markets based on the correlation coefficients have been analyzed. Firstly, similar to the previous studies on the global stock indices using MST length, the diversification effects in the global multi-asset portfolio can disappear during the crisis as the correlations among the asset class and within the asset class increase due to the system risks. Second, through the network visualization, we found the clustering of the asset class in the global financial markets network, which confirms the possible diversification effect in the global multi-asset portfolio. Meanwhile, we found the changes in the structure of the network during the crisis. For the last one, in terms of the degree centrality, the stock indices were the most influential to other assets in the global financial markets network, while in terms of the betweenness centrality, Gold, Silver and AUD. In the practical perspective, we propose the methods such as MST length and network visualization to monitor the change of the correlation risk for the risk management of the multi-asset portfolio.

The basic assumption is that the preceding factors that can be determined by the personal investment propensity, a psychological factor asserted by Behavior Financial Theory and financial-economic and social environment. This study uses Hershey's Investment Behavior Model(2007) as the main analysis tool to explain the investment behavior of individuals and deals with personal investment inclination in the psychological perspective of overconfidence, self-control and the risk tolerance propensity and add the financial and economic factors in terms of financial literacy and economic distress. Also the new preceding social environmental factors like social interaction and the effect of reference group are added to make this research to be more precise. This study analyze the adjustment effect of professional invest-consulting service that affect the fluctuation influence between the individual variables(those factors) and subordination variable(the level of investment satisfaction). The study reveals that overconfidence and self-control in direct ways have a positive effect on the level of investment satisfaction in terms of investment behavior and economic distress has a negative effect on the level of investment satisfaction. The adjustment effect provided by financial experts in investment consulting service is affirmed as the critical factor that increase the influence between self-control and the level of investment satisfaction. To conclude, the research reveals that the psychological factors are the main criteria when the workers as employees have to make investment decisions. To make investors be reasonable, a systematic financial education system provided by experts is needed from the early adolescent stages and financial companies should develop the relevant services of consulting service department as a key financial sector and financial investment products and consulting program and marketing tool pertinent to investors ages, vocational traits and their inclinations.
