One of key success factors in PPI(Public Private Investment) is the structure of risk sharing between the public and the private, and the determination mechanism of fair return to private participants relative to the risk that private participants undertake. In Korea, two basic types of PPI exist. One is BTO and the other is BTL. In BTO, most risks are taken by the private whereas the opposite is the case in BTL. No intermediate form exists. As a result, BTO type projects had difficulty in attracting private participants because of the excessive risks. In this study, one intermediate form is studied where demand risk is shared between the public and the private. In the setting where the public authority takes all the project revenues and then pays ladder type payments to private participants depending upon the level of project revenues, appropriate level of fixed payments is endogenously derived using the real option pricing model. From the fixed payments, expected investment returns are calculated based upon a certain distributional assumption. The results of this study is expected to help introducing diverse forms of PPI in Korea.

Crowdfunding recently receives a great deal of attentions as an alternative finance for small and medium-sized enterprises or business ventures that suffer from financial constraints. Crowdfunding is a new form of platform that enables a large number of people to invest a small amount of money for promising new business items directly. We analyzed the effect of type, period, method of projects on crowdfunding outcomes. We measure the outcome in terms of the ratio of the collected to the target amount. We collected data from three Korean crowdfunding platform companies, and the data consisted of 239 projects from 2012 to 2014. We use both logit and ordinary least square method for evaluation. Generally, the amount of target itself has no effect on the outcome. Equity crowdfunding shows higher success rate and better outcome than rewards crowdfunding. All or Nothing method leads to the higher ratio of the collected to the target amount than Keep It All. There is an inverted U-shape between the number of investors and the ratio of the collected to the target amount. Finally, the ratio of the collected to the target amount is decreasing in a crowdfunding period.

Based on social capital theory, this study investigated the influence of the start-up founder's social competence on the start-up's access to funding sources and performance through the mediating role of the type of social network. This study aimed to examine two types of social networks empirically (i.e., personal networks and business networks) as social capital in analyzing the effect of the founder's social competence and social capital on the method of accessing funding sources. A self-report questionnaire was administered to 252 South Korean start-up founders whose businesses are based in South Korea. Path analysis and mediation effect analysis were performed by structural equation modeling(SEM) using STATA 16.1. This study examined the full mediating effect of the founder's social competence on his/her personal and business networks, respectively, and how the effect leads to different methods to approach funding sources. This is the first study in South Korea to analyze empirically how social competence has contrasting effects on personal and business networks as well as how each type of network varies in its influence on the method founders use to attract investment. This study is also significant in that it proposed a new methodology by utilizing the position generator as the measure of personal and business networks to analyze social networks in detail. The analyses of 252 survey data collected over a period of six months will be a valuable resource that may provide researchers, founders, investors, and other stakeholders in the start-up ecosystem with meaningful implications.

부동산 간접투자 여건을 개선하여 자금흐름의 선순환을 유도하는 것이 부동산 실물 투자 욕구를 흡수할 수 있는 효과적인 대안으로 보인다. 지난해 아파트시장에 이어 토지시장이 다시 들썩이고 있다. 정부의 각종 투기억제정책 등으로 투기가 확산되기는 힘들겠지만 시중 유동성이 자본시장 등으로 선순환되지 않는 한 부동산투기는 언제든지 재현될 가능성이 남아 있다. 부동산 투기가 상품을 바꿔가면서 반복되고 있는 가장 큰 원인으로는 저금리 기조에 따른 풍부한 유동성과 부동산 간접투자상품 등 대체투자 수단이 다양하지 못한 점을 들 수 있다. 이에 부동산 직접투자의 대안으로 부상하고 있는 부동산 간접투자 여건을 진단해 본다.

Korean port developments have been mostly made by the central government. With the introduction of the Port Authority system, however, roles and function assignments of the central government in port development have been in change and the Port Authority has to find a solution for inducement of private investment in port development. This paper has examined the current legal system of port developments and then sought the way for inducement of private capital to improve specialty and efficiency of harbor facilities management and development under Port Authority. As the Ministry of Maritime Affairs and fisheries(MMAF) has two types of legal system for inducement of private investment on port developments, the Port Authorities can also have two types of private finance. Private finances by the Port Authorities has some more critical advantages than the one by the central government. It is also required to change the the administrative permissions and concession agreements which MMAF conveyed to private participants in port developments into the concession agreements between Port Authorities and private participants.

This study examines public libraries being built using the BTL (Build-Transfer-Lease) method, which is one type of Private Finance Initiative, in order to investigate effective ways of building public libraries in Korea. A literature search, field research and interviews were the methods used for the study. One library was built and eight other libraries are in the process of construction using the BTL method in six cities in Korea in 2008. The study revealed that the bigger libraries are being built using the BTL method. The study suggests that in order to effectively increase the public library infrastructure within a short period of time in Korea, smaller libraries should be built using the BTL method.

In this study, traditional treatment scenario of food wastes that collected and transported food waste is recycled in large treatment facilities and suggested treatment scenario of onsite zero discharge system that food waste is treated in housing complex were supposed. The scenarios were compared and analyzed by capital expenditure, oil consumption, $CO_2$ emission quantity, operating expenditure and management expenses. The capital expenditure, oil consumption and $CO_2$ emission quantity of small scale dispersion dealing method is the lowest compared to traditional treatment method. As a results, it is possible to obtain the effect that operating expenditure was reduced by 91% and management expenses was reduced by 40% with suggested treatment method. The treatment method that have low capital expenditure is tend to lower oil consumption and $CO_2$ emission quantity. The small scale dispersion dealing method have the lowest capital expenditure, oil consumption and $CO_2$ emission quantity and the linked method with sewage treatment have the highest expenditure and $CO_2$ emission quantity. Eventually, the optimal model of onsite zero discharge system in housing complex is small scale dispersion dealing method.

본 논문에서는 코일을 이용한 비접촉 방식의 맥박 측정 시스템의 효율적인 설계 방안을 제시한다. 인덕턴스와 커패시턴스의 값에 따라 발진 주파수가 변동되는 콜피츠 발진기를 사용함으로써 혈류의 흐름에 따른 인덕턴스의 변화를 측정하였다. 실험은 2가지로 구성되며 첫 번째는 코일 위에 손가락을 올려놓은 상태로 측정하는 방식이며 두 번째는 반지 형식으로 감겨진 코일을 손가락 끝에 착용하였을 때이다. 코일 내부에서 가장 높은 자력선 밀도를 가지므로 첫 번째 방식보다 두 번째 방식에서 더 높은 투자율의 변화를 감지할 수 있다. 결과적으로 광용적맥파 신호와의 비교 실험을 통하여 맥파로서의 유의성을 검증하였다.

본 연구는 스타트업 투자성과와 연계된 창업가 역량, 재무정보 등 정량데이터를 기반으로 스타트업 투자자들의 투자결정요인을 분석하였다. 주요 실증결과는 다음과 같다. 첫째, 창업 초기 종업원 수가 많고, 최고경영자의 지분비율이 높을수록 투자승인 확률이 높게 나타났다. 둘째, 재무적 특성에서는 기업의 매출액 규모가 작을수록 투자승인 확률이 높게 나타났다. 이러한 결과는 스타트업의 경우, 기업의 단기성과보다는 투자 결정에 있어 미래가치 혹은 다른 정성적인 요인이 더 고려된다는 점을 보여준다. 셋째, 창업가 특성에서는 CEO 교육수준(학력)이 높을수록 투자승인 확률이 높게 나타났다. 즉, 창업자의 학력은 성공적인 투자 여부에 핵심적인 변수이고 이것은 선행연구의 결과와 다르지 않았다. 또한, 학력과 투자유치의 연관성은 창업 3년 미만 스타트업에서 상대적으로 강하게 나타났다. 선행연구에서 투자정보공개, 관련 데이터 확보의 어려움으로 스타트업 투자에 관한 정량적 실증연구가 거의 진행되지 못한 점을 고려한다면, 본 연구는 설문조사 방식을 뛰어넘어 국내 초기 창업기업만을 대상으로 성공적인 투자유치와 연계된 스타트업의 평가요인을 정량적으로 분석했다는 점에서 중요한 의의를 갖는다.
