정부는 사회간접자본에 대한 민간의 창의성과 효율성을 도입하고 민간의 여유자금을 활용하여 정부의 재정 부담을 줄이기 위한 방편으로 1994년 민간투자제도를 도입하였으며, 2005년 "사회간접자본시설에 대한 민간투자법" 개정을 통하여 제도상의 많은 변화를 이루어 왔다. 민간투자사업의 사업자 선정을 위한 사업계획서 평가업무는 사업제안자의 사업 수행 능력 및 자질을 평가하는 단계로서 민간투자사업의 공정성과 투명성을 확보하기 위해 가장 중요한 단계라 볼 수 있다. 본 연구에서는 한국개발연구원 공공투자관리센터에서 제공한 사업계획서 평가관리 세부요령을 토대로 현행 민간투자사업 사업계획 평가업무의 분석 및 문제점 도출을 통해 공정성과 투명성이 확보 가능하도록 단계별 수행업무를 보완하여 개선방안을 제안하였으며, 보다 효율적으로 평가업무가 수행되어질 수 있도록 사용자 편리성, 공정성 및 업무효율성 제고를 위하여 사업계획서 평가관리 프로그램을 개발하였다.

본 연구는 한국 민간투자사업의 위험배분문제와 화폐적 투자가치를 측정하는 모형을 구축하고 이를 통해 정부의 최소운영수입 보장률 및 보장기간의 변화에 따른 화폐적 투자가치의 변화를 관찰하였다. 모형은 H.Yamaguchi의 위험배분모형(2002)을 기반으로 한국의 민간투자사업 현실에 맞게 2기간 모형으로 변환하고 최소운영수입보장 제도를 포함하도록 수정하였다. 분석결과 정부의 최소운영수입 보장률 및 보장기간이 축소됨에 따라 동일한 수익률을 가정하는 경우 국고보조금이 증가하게 됨으로써 민간투자사업의 화폐적 투자가치는 하락함을 보여주었다.

Effective implementation of private subsidy projects requires comprehensive expertise in the aquaculture and construction sectors to be provided to private subsidy operators, local government officials and others involved in budget execution and settlement. Due to the strengthening of laws and systems related to the execution of state subsidies since 2015, the efficient implementation of private-sector grant projects has been difficult for delays in projects, cancellations, and conflicts with local governments from lack of prior awareness and understanding of related regulations. It is expected that the government will be able to activate the project by analyzing the current status and problems of each phase of project implementation for improving quality internalization of the project effects, as well as quantitative growth of the private sector subsidy project for environmentally friendly aquaculture development projects.

Because the existing BIM platform is based on user services, the focus is on the development of SaaS (Software as a Service), which provides business services online. However, since a harbor is a security facility, the harbor BIM platform is preferably provided in a private form, rather than relying on the infrastructure environment provided by external cloud providers. Therefore, this study analyzes and reviews the main functions to be provided as SaaS services of the harbor BIM platform. The goal is to build a cloud-based harbor BIM platform that can provide this service to users. To this end, we built IaaS (Infrastructure as a Service) environment of the harbor BIM platform based on the open source Open Stack and integrate and develop PaaS environment with Open Shift applied with IaaS. We applied the GPU to the harbor BIM platform to verify the performance of the harbor BIM platform, and found that the rendering and loading times are improved. In particular, it is expected to reduce the cost of introduction and provide it as the basic cloud environment of similar BIM platform for infrastructure facilities.

The aim of this study was to identify community-level childcare infrastructure for infants and toddlers and to use the data to categorize community types using K-Means cluster analysis with spatial constraints. Seven indicators of childcare resource supply were used for the purpose of categorization and the results revealed six types of community cluster. Communities in the Type 1 cluster provided sufficient parks, libraries, and kindergartens, but lacked pediatric facilities and private education institutions. This cluster comprised small cities and rural areas in Gangwon-do, Gyeongsangbuk-do, Chungcheongbuk-do, and Jeollabuk-do. The Type 2 cluster had numerous pediatric facilities and childcare centers, but lacked other childcare infrastructure. This comprised small and medium-sized cities in Gyeonggi-do, some areas in Chungcheongnam-do, Chungcheongbuk-do, and Gangwon-do bordering Gyeonggi-do. The Type 3 cluster comprised Busan, Daegu, and Gyeongsangnam-do, but had insufficient childcare infrastructure as a whole. Type 4 had the largest number of childcare centers, libraries, and private education institutions and comprised Jeollabuk-do, areas near Gwangju, and Jeju-do. Type 5, consisting of Seoul, Incheon and the southern part of Gyeonggi-do had many pediatric facilities and certified childcare centers, but lacked other childcare infrastructure. Type 6, being the rural areas and islands in Jeollanam-do, had sufficient kindergartens, but other infrastructure was insufficient. These results are expected to provide local government with policy implications in terms of relieving the childcare burden on residents with infants and toddlers.

In order to widen the radius of electric vehicle (EV) travel recharging points must be provided in sufficient numbers and at convenient places. The cost of providing side an infrastructure is at preset, not well documented and this lack of information acts as a detersent to prospective insestors in EV technology. This paper acts as a preliminancy investigation into the cost of infrastructure is the different situation i.e for the private owner, the fleet owner or for the public. It provides an overview of the items required and this relative costs. Cost will however, vary from country to country and application to application, and this paper two acts purely as guide to the type of equipment and its relative costs.

This study investigates the effect of infrastructure, economic sectors and its status, foreign direct investment and private investment, as well as the role of political stability in enhancing the tourism demand in the ASEAN region. The research collected the secondary data from the World Bank database and the UNWTO website of 10 ASEAN countries over 17 years from 2000 to 2016. Applying the generalized method of moments, this research found that, "private investment", "economic sectors", "exchange rate and infrastructure measured by "using of the internet" can increase the tourism demand of a country in the ASEAN region. This research provided evidence indicating that the "foreign direct investment" and "inflation" are two detrimental factors for tourist attraction. The major finding confirmed the positive role of "political stability" in increasing tourist arrivals. First, attracting tourists to a country always poses many challenges to its government. It has been observed in the past decades that though there were many documents, which confirmed that industry can help in promoting tourism, very few studies investigated the role of both agriculture and manufacturing sectors in tourism promotion. Secondly, there are only a few studies which verifies the stability of the political system to the tourism demand in the ASEAN region and that this variable (political stability) has the strongest impact.

Healthcare is one of the biggest industries that consume IT Infrastructure as a necessity. A reliable reach to secure private information is the essential goal. Most of the healthcare organizations either have their own custom solutions developed or third part CRM software tailored to their needs. This culture satisfies the usability internal to the organization but lacks the ability to provide public access to the users or even to take a step ahead and collaborate with like minded institutes for research and potential growth. Emergence of cloud computing has provided us the opportunity to take a step ahead and build applications available to users on a secure platform, with ability to scale the resources depending on the requirements. The effective use of hybrid and community cloud can create rock solid foundations for healthcare IT Infrastructure. These cloud deployment models not only caters the present needs of healthcare IT Infrastructure but also opens the possibilities to build applications and provide secure and reliable access beyond the limits of organizational boundaries.

정보보호의 중요성이 인식되면서 암호 기술의 사용이 증가하고 있다. 특히, 공개키 암호 기술은 대칭키 암호기술에 비해 키의 관리가 용이하고, 디지털 서명을 쉽게 구현할 수 있다는 장점을 가지고 있어서 그 사용이 증가하고 있다. 현재 공개키 암호 기술을 효율적이고 안전하게 사용하기 위한 공개키 기반 구조가 구축되어 운영되고 있다. 공개키 기반 구조에서는 사용자가 인증기관에 등록하여 개인키와 공개키 쌍을 생성하고, 인증기관은 생성된 공개키에 대한 인증서를 발행한다. 이러한 인증서를 이용하여 사용자간에 키 설립을 수행하고 암호화통신을 할 수 있게 된다. 그러나 공개키 기반 구조에서 설립된 세션키에 대한 관리 기능은 제공하고 있지 않다. 본 논문에서는 무선 인증 및 키 설립시 설립된 세션키에 대한 키 복구를 지원하는 인증서 발행 프로토콜을 제안한다.

본 연구에서는 우리나라에서 시행되었던 BTO 민간투자사업의 자료를 이용해 BTO 민간투자사업에 투자되는 민간자본에 대한 적정수익률을 추정하고자 한다. 과거 우리나라에서 진행되었던 민간투자사업의 경우 민간자본에 제공된 실질수익률은 대략 $6%\sim9%$ 수준이었는데, 본 연구의 결과에 따르면 정부가 최소운영수입을 보장해준 과거 민간투자사업의 경우, 민간자본에게 제공되었던 수익률은 적정 수준을 상당히 초과하는 것으로 나타났다. 특히 대부분의 민간투자사업에 있어 실제 운영 수입이 실시협약 당시 예측된 운영수입에 현저히 못 미친다는 점을 고려할 때, 민간자본에 대한 적정수익률은 더 낮아지게 되며 따라서 과거에 제공된 수익률의 적정수익률 대비 초과분은 더욱 커지게 된다. 본 연구결과는 향후 BTO방식 민간투자 사업을 진행할 때 정부와 민간사업자간의 실시협약조건에 민간 사업자가 부담하는 위험 대비 적정수익률이 반영될 수 있도록 하는데 도움을 줄 것으로 예상된다.
