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.

Edible insects are an interesting alternative global food resource. The purpose of this study was to investigate whether ingestion of silkworm (Bombyx mori) pupae powder with and without resistance exercise training (isometric contraction training) increased muscle mass in ICR mice. To achieve this, 28 ICR mice were grouped into control (CON), resistance exercise training (EX), silkworm pupae powder ingested control (SP), and silkworm powder ingestion with resistance exercise training (SPEX) groups. The change in body weight ratio was significantly decreased in the EX and SPEX groups compared to the CON and SP groups. Total blood protein levels were the highest in SPEX mice compared to those in other groups. The albumin concentration increased only in the EX group. Blood GOT and GPT levels were not significantly affected. Changes in Akt and Gsk-$3{\beta}$ protein expression were not significant but there was a tendency for Akt to increase and for Gsk-$3{\beta}$ to increase following the ingestion of the powder. The size of the gastrocnemius muscle increased significantly in response to resistance exercise training only. Furthermore, the ingestion of silkworm pupae powder tended to increase muscle mass without significance. These results suggested that the ingestion of silkworm pupae powder with resistance exercise training might enhance muscle mass without hepatotoxicity. However, future study may be needed to obtained detailed results and practical suggestions.

The number of volcanoes erupted during the past ten thousand years(Holocene period) on this planet is known to stand around 1,520. Of those volcanoes, the number of active volcanoes during the six-years and seven-month period(January 2010 through the end of July 2016) is totals 209. These findings show that an average of approximate 90 volcanoes erupted every year since 2010. It is also found that over 90 percent of those active volcanoes took place in the circum-Pacific volcanic belt, which is commonly called 'Ring of Fire'. This status coincides with the distribution maps of active volcanoes on the earth: about 80 percent on subduction zone of the convergence of lithospheric plate; 15 percent on spreading zone; 5 percent on intra-plate zone. The period given in this research during 350 weeks, the following three volcanoes showed a frequency of more than 300 times eruption: Kilauea(Hawaii, USA, 338 times), Sheveluch(Kamchatka, Russia, 337 times), and Aira(Kyushu, Japan, 301 times). According to the survey conducted during the given period, there is no conspicuous increase in the frequency of volcano activities. It rather shows that volcanic eruptions took place almost evenly every year.

Recently, with coming of various channels, the public are communicating with unspecified massive consumers through personal broadcasting. It is becoming more popular as a positive response. The purpose of this study is to investigate the effect of characteristics of personal broadcasting contents on perceived value, perceived value on continuous use intention and the interaction effect of novelty seeking. As a result of verifying the effects of information quality, information trust, and entertainment on the perceived value, the characteristics of personal media contents all showed a significant positive effect and perceived value has a positive effect on continuous use intention. But The interaction effect of novelty seeking and perceived value is not significant. Therefore, content creators should make efforts to create content as much as to the trust of content as entertainment elements in content and composition. In the future, it will be meaningful to proceed with the research on the direct effects of the novelty trend and the various factors affecting viewers' characteristics using personal media contents.

This study interprets the corporate social responsibility and its management through analysis of philosophical view of Mozi(墨子). Mozi was a chinese philosopher during the Hundred Schools of Thought period. He advocated Universal love(兼愛), which stresses that people should care for everyone equally. This principle is in accord with the sustainable management strategy for global market environments. The realization of the value that the company pursues in the rapid growth of such enterprises is an important issue. The pursuit of corporate value in its own interest under the rapidly changing business environment is perceived very negative. And it has demanded a different philosophy as a new management philosophy. The philosophical strategies of these companies were centered around the core philosophy of the ancient Chinese philosopher, Mozi. It is not merely an outcome approach as the act or moral principle but the inner motive to love each other and the principle of sharing the profits of each other. In order to pursue the sustainable value of the enterprise, We would like to suggest a way to pursue the existing absolute value, and to suggest a philosophical strategy based on the philosophy of Mozi.

The main purpose of the research is to illustrate the value of the spatial statistical approach to residential differentiation by providing a framework for exploratory spatial data analysis (ESDA) using a local spatial separation measure. ESDA aims, by utilizing a variety of statistical and cartographic visualization techniques, at seeking to detect patterns, to formulate hypotheses, and to assess statistical models for spatial data. The research is driven by a realization that ESDA based on local statistics has a great potential for substantive research. The main results are as follows. First, a local spatial separation measure is correspondingly derived from its global counterpart. Second, a set of significance testing methods based on both total and conditional randomization assumptions is provided for the local measure. Third, two mapping techniques, a 'spatial separation scatterplot map' and a 'spatial separation anomaly map', are devised for ESDA utilizing the local measure and the related significance tests. Fourth, a case study of residential differentiation between the highly educated and the least educated in major Korean metropolitan cities shows that the proposed ESDA techniques are beneficial in identifying bivariate spatial clusters and spatial outliers.

This study aims to provide policy suggestions on how to implement the process of empowerment, by investigating the conditions that hinder the process and the attitude of the KBS employees. For the cross-sectional study, this thesis examined the domestic and international references, conducted a survey of KBS employees, personal interviews and made direct observations. Approximately 1,200 copies of the questionnaire were distributed and 474 were completed and returned. The analysis used SPSS 12.0 software to process the data collected from 460 respondents. The survey findings showed a decrease of 24.2%p in the number of responses expressing negative views of the team structure and a decrease of 1.29%p in the number of positive responses. The findings indicated a positive transformation illustrating employees' improved understanding and approval of the team structure. However, KBS must address the issue on an ongoing basis. It has been proven that the employee empowerment increases the productivity of the individual and the group. In order to boost the level of empowerment, the management must exercise new, innovative leadership and build trust between the managers and the employees first. Additional workload as a result of shirking at work places was prevalent throughout all divisions and ranks, according to the survey data. This outcome leads to the conclusion that the workload is not evenly distributed or shared. And the data also showed the employees do not trust the assessment and rewards system. More attention and consideration must be paid to the team size and job allocation in order to address this matter; the present assessment and rewards system need to be complemented. The type of leadership varies depending on the characteristics of the organization's structure and employees' disposition. KBS must develop and reform its own management, leadership style to suit the characteristics of individual teams. Finally, for a soft-landing of KBS team structure, in-house training and education are necessary.

Global warming has recently become an issue that has resulted in a growing trend to minimize environmental pollution. The International Maritime Organization (IMO) has shown that the majority of marine atmospheric pollution occurs as a result of emissions from marine vessels. Therefore, the environmental regulations and emission standards regarding marine vessels have gradually become stricter, and the research and development in this area is experiencing significant progress. In this study, a nozzle for a fuel oil scrubber was investigated using computational fluid dynamics (CFD) and particle imaging velocimetry (PIV). Experiments were conducted on scaled-down model of the scrubber to determine its performance, which was then compared with CFD results. Based on the experimental results, it was found that at a spray angle of $66^{\circ}$, the spray velocity at the nozzle was 20.1 m/s. From this comparison, a full-scale scrubber model was analyzed using CFD, and the effect of the positioning of the nozzle was studied.
