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.

Inverse synthetic aperture radar(ISAR) image generated from bistatic radar(Bi-ISAR) represents two-dimensional scattering distribution of a target, and the Bi-ISAR can be used for bistatic target identification. However, Bi-ISAR has large variability in scattering mechanisms depending on bistatic configurations and do not represent exact range-Doppler information of a target due to inherent distortion. Thus, an efficient training DB construction is the most important factor in target identification using Bi-ISARs. Recently, a database construction method based on realistic flight scenarios of a target, which provides a reliable identification performance for the monostatic target identification, was applied to target identification using high resolution range profiles(HRRPs) generated from bistatic radar(Bi-HRRPs), to construct efficient training DB under bistatic configurations. Consequently, high identification performance was achieved using only small amount of training Bi-HRRPs, when the target is a considerable distance away from the bistatic radar. Thus, flight scenarios based training DB construction is applied to target identification using Bi-ISARs. Then, the capability and efficiency of the method is analyzed.

Physical properties and textural parameters of thirty-five piston tore samples recovered from the southeastern coast of Korea (Korea Strait), were investigated using the autopycnometer. The physical properties (porosity, water content, wet bulk density, dry bulk density, gram density, and void ratio) were measured at rather uniform intervals along each core. Sediment texture (grain size, sand, silt, and clay contents) was also measured at the same subbottom depth. The measured and calculated results are; mean grain size $0.57\~8.09\phi(average:3.67\phi)$, porosity $26\~81\%\;(average:\;55\%)$, water content $16.7\~61.4\%(average:\;31.6\%)$, wet bulk density $1.37\~2.18g/cm^3\;(average:\;1.85g/cm^3)$, dry bulk density $2.55\~3.11g/cm^3\;(average:\;2.35g/cm^3)$, grain density $2.40\~3.10g/cm^3\;(average:\;2.85g/cm^3)$, and void ratio $0.56\~2.54$ (average: 0.94). The sediment texture generally coincides well with the bathymetry indicating the influence of Pleistocene-Holocene sea level changes. Also the contours of physical properties are closely related to the sediment texture. Fluctuation of physical properties are similar to the textural variation. It seems that sediment texture is a significant factor in determining physical property in this study area.

An accurate feedback about customer satisfaction is a very important factor to efficiently manage achievements in the service industry. However, Korea is lack of quantitative and standardized system of customer satisfaction measurement. This paper suggests standardized survey system with more in-depth and various methods of questionnaire survey as well as analysis which is able to efficiently evaluate customer satisfaction. This system is that investigates customer satisfaction of process based services, which uses various methods including simply designed questionnaires, customer satisfaction survey via mobile, and an investigation on follow-up satisfaction rate. In addition, we adopted scoring system to digitize a degree of satisfaction rate, so the suggested system provides an opportunity to improve specific objects those need to be improved by clearly evaluating a degree of satisfaction rate and applying various analysis techniques, such as IPA (Importance Performance Analysis), process analysis, and expectation analysis etc. This study substantiates suggested system through applying it to travel agency which is a representative enterprise of tour service.

This research was implemented to check what effects entrepreneurship have on the entrepreneurial intention verify the emotional factor 'Fear on Business' in terms of the relationship between entrepreneurship and the entrepreneurial intention. Above all, in the study Health Belief Model was applied to research into emotional factors, such as 'Fear on Business'. Specifically, it was performed to check what effects 'Fear on Business' has on the entrepreneurial intention and to see if there are any mediating effects between entrepreneurship and the entrepreneurial intention. To achieve the research purposes above, the students who took a business start-up and entrepreneurship related course were surveyed (all 356); and research findings were produced. To summarize the findings, entrepreneurship did influence the entrepreneurial intention significantly. In addition, entrepreneurship significantly influenced 'Fear on Business'. And 'Fear on Business' significantly influenced the EI; it turned out that 'Fear on Business' plays a mediating role between entrepreneurship and the entrepreneurial intention. From these result, it is thought that programs or policies for reducing 'Fear on Business' are needed. Finally, because entrepreneurship can affect the entrepreneurial intention through the medium of 'Fear on Business', it is thought that the government's effort to create a social atmosphere is needed to overcome 'Fear on Business'.

This article analyzes the latest cases of Digital Social Innovation such as crowdsourcing and online petitions for public trouble-shooting in oder to demonstrate that public engagement of the citizens on decision making can enhance the quality of democracy. Digital Social Innovation contributes to citizen's participation on decision making and policy implementation with taking advantage of digital technologies of crowdsourcing and online petitions. Active civic engagement for decision making literally helps to improve and democratize government policy. These series of processes not only improve quality and efficiency of policy governance by building up transparency and effectiveness of policy itself but also enhance the throughput legitimacy. With this article, I quote and analyze various practices of Digital Social Innovation which we had substantiated to demonstrate the effectiveness of civic engagement for decision making to improve and enhance democracy. The hypothesis that the Digital Social Innovation attempted in various ways is a principal factor of democratization could be verified. Moreover, the practices of Digital Social Innovation helps the civic participation in policy making in modern society. Finally, this article suggests an implication of Digital Social Innovation as part of efforts to ensure the involvement of throughput legitimacy for the development of democracy.

The objectives of this research are to investigate the mechanism of coagulation affecting UF, find out the effect of metal salt coagulant on membrane fouling. Either rapid mixing + UF or slow mixing + UF process caused much less flux decline. For PACl coagulant, the rate of flux decline was reduced for both hydrophilic and hydrophobic membrane than alum due to higher formation of flocs. In addition, the rate of flux decline for the hydrophobic membrane was significantly greater than for the hydrophilic membrane, regardless of pretreatment conditions. In general, Coagulation pretreatment significantly reduced the fouling of the hydrophilic membrane, but did little decrease the flux reduction of the hydrophobic membrane. When an Al(III) salt is added to water, monomers, polymers, or solid precipitates may form. Different Al(III) coagulants (alum and PACl) show to have different Al species distribution over a rapid mixing condition. During the rapid mixing period, for alum, formation of dissolved Al(III) (monomer and polymer) increases, but for PACl, precipitates of $Al(OH)_{3(s)}$ increases rapidly. This experimental results pointed out that precipitates of $Al(OH)_{3(s)}$ rather than dissolved Al(III) formation is major factor affecting flux decline for the membrane.

It is necessary for inmates released from prison to recover their career capital in order to function normally in society. Failure to adapt to the society may not only make them unhappy but could also aggravate social safety nets. Therefore, it is critical to examine the recovery of career capital. For this study, we conducted in-depth interviews of 10 rehabilitation recipients who were supported by Korea Rehabilitation Agency. For qualitative analysis, several career topics were analyzed, such as obstacles in recovering career capital, efforts in overcoming these obstacles, what is helpful for them to overcome the obstacles and what is required for them to adapt to the career life and others. Analysis results found that the rehabilitation beneficiaries suffered loses to their career capital due to their incarceration, suffered from the loss of pride and became despondent in the process of recovery of career capital due to the negative social perception toward their social self, fear of social stigma and devaluation of themselves. In addition, the fear of possible negative evaluation was a critical factor in making their social activities more challenging. Conversely, it was found that social support in the recovery process of career capital has a positive effect. In particular, emotional support from spouses, employers, family members and friends are the most positive factors. Concerning efforts at adapting to careers, it was found that an active, leading and positive attitude toward the career were critical, showing that positive evaluation and recognition in family and social relations and the experience of success in the career were positive elements in enhancing a sense of pride. In summary, it was found that in the recovery process of career capital, dysfunctional beliefs had a negative effect, while social support had a positive effect, on the recovery of career capital.

Defense technology planning identifies medium-and long-term core technologies to accomplish future defense goals and suggests strategies for future R&D. In order to promote the export-oriented defense industry, planning paradigms should be shifted from technology-oriented planning that focuses on weapon systems to market- oriented R&D planning. This study aims to strategically support 'preliminary technology planning' the Defense Agency for Technology and Quality is pushing ahead with. Through market-orientation analysis models of weapon systems based on defense R&D planning, data research on previous market-oriented research, and the analyses and examples of global defence markets, it evaluates market attractiveness to UAVs and drew methods for exploring markets and enhancing competitiveness of military equipment. The market-oriented analysis model of weapon systems is considered to be a helpful reference as a relevant factor for decision making on establishing and verifying requirement planning. In particular, if a market-oriented defense R&D planning process is established institutionally, it will enable us to make export strategies tailored to different equipment from the planning phase and to support marketing strategically.
