Harbor and bay is essential social overhead capital to our country economy national security. This harbor and bay is ever-present danger of marine accident by massed sea traffic discharge. A nautical mark in sea maintains safety of sea traffic and establishes in sea for increase of efficiency of ship service to prevent this sea accident. In this study, position of light buoy that establish for safety of harbor and bay that decided adjacent district along the coast base point by utilization method of intersection and evaluated and compares with DGPS measurement techniques.

The aim of this study is to develop suitability site indicator of urban-rural return to fishing and to analysis priority of the indicators. The study is based on literature review, expert survey and AHP(Analytic Hierarchy Process) methods. This study found 5 factors(natural environment, acceptance environment, social overhead capital, economy, fishing environment) and 21 detail variables. as a result of AHP, fisheries resources, acquisition convenience of fishing license, income(except fishing), attitude of local resident, one-person household income, high income fishing were showed high priority. This result indicate that economic foundation is most important factor for suitable site of the returning.

In the current world, with the massive scale of SOC construction, it is difficult to diagnose and check all of a bridge's abnormal states with even the experts' eyes for maintenance. It is because we should spend huge costs and time on maintenance. Still, there are not many alternative ways to inspect bridges remotely regarding accuracy or reality. Therefore, we remark on the advantages and disadvantages of previous methods through practices in SOC maintenance. To inspect the abnormal state of the Bridge, we suggest inspecting bridges with an Augmented Reality (AR) mechanism to reduce cost, human resource consumption, and the risk of work. Through the proposed approach, we expect that it provides ways to solve massive construction problems with software-based technologies.

In this study, in order to understand the needs for infrastructure services experienced by the public, we compared the level of infrastructure service satisfaction and analyzed the characteristics of infrastructure services by region. In this study, as a result of comparing the level of infrastructure satisfaction between regions, transportation and living infrastructure services were generally low. However, the characteristics of infrastructure services within the region are clearly different from the results of the infrastructure satisfaction between regions. Therefore, it is necessary to examine the level of infrastructure satisfaction within the overlooked region, and the satisfaction, improvement importance, respondent characteristics, and quantitative indicators need to be considered.

급변하는 정보기술의 발달로 국제적인 이슈로 떠오르고 있는 전자정부는 국내 정보통신분야에서도 많은 관심을 보이고 있다. 그러나 국가자격증의 경우 전자정부와 연관성이 많지만 전자정부를 추진하는데 있어서 국가자격증과 관련한 내용은 언급되고 있지 않다. 본 논문에서는 국가자격증의 하나인 보육자격증 중심에서 국내 전자정부와 보육자격증의 연계방안을 제시 하고자 한다. 보육자격증 연계방안의 목적은 전자정부에서 제공 받을 수 있는 주민등록등본, 지방자치단체에서 관리하는 경력 정보를 기반으로 학교, 교육원의 정보를 제공받아 고객중심의 서비스 행정을 구현 할 수 있으며 접근성의 제고를 통해 투명성과 신뢰성이 있는 열린 행정을 구현 할 수 있다. 또한 이러한 통합망은 국가존립 및 발전을 위한 하나의 큰 아젠다(Agenda)인 보육의 체계적 발전을 위한 사회간접자본(SOC:social overhead capital)으로서의 역할을 기대할 수 있다.

The conventional non-dig underground structure building method which made an appearance to reduce the social and environmental costs and maximize the efficiency of the social overhead capital facilities could not help being uneconomical because of many problems such as unnecessary excessive excavation, water leakage, obstacle interference, difficulty of curvilinear application and connection complexity between propelled and injected bodies due to indiscriminate application of small and large circular steel pipes without consideration of the site conditions. The T.S.T.M, in which a protruded square tube is applied as a propulsion and injection body in a design that considered site conditions such as ground condition, depth of soil and live load, was able to be economical as it solved the problems of water resistance, minimization of obstacle interference and curvilinearity, and we can see that it can be applied to all grounds by utilizing or complementing the target ground in terms of engineering. Also in configuring the transverse section, it is possible to not only secure excellent structural safety but also implement all of the above engineering characteristics not only in the square cross section but also in the arch cross section, so it was possible to build structures on any section or ground, and we could confirm the LCC reduction effect and the VE effect.

As economic trade between Korea and China has been encouraged with the rapid growth of Chinese economy and port competition in Northeast Asia, Korean government is trying to promote development and consolidation of ports to cope with the lack of facilities. Thus, many projects for port development have been propelled including the enactment the 'Private investment promotion law for social overhead capital 1994.' However, there are still some unsettled issues since considerable part of risk is still allocated to the Government when it has to support the private businesses in these port investments whenever unexpected problems arise. Allocation of risk among the participants - in this case especially - is a very subtle issue, however, it was revealed that not many precedent researches were done on the subject. In my previous research, I classified and analyzed 4 principle risks i.e, construction, management, financial and social risk. This research investigates the reasonable allocation of the risks among the participants using the Hierarchial Fuzzy Process. In the result of analysis, responsibility of private party is the most important and it must put the responsibility before Government' roll concerned. Also, this research displayed and proposed the direction of management method on port development in a view of minimizing risk and maximizing initiative of a private party.

Sustainable development goals (SDGs) are designed to promote human and social development and address challenges related to sustainable economic development, in addition to creating quality employment. SDGs create new market and business opportunities that enable companies to effect business changes through innovative solutions. To tackle structural problems and create infrastructure for future societies, a national-level digital transformation strategy is being developed in Korea. The Korean government announced an investment plan for living social overhead capital (SOC) to address various social and structural problems caused by low economic growth. This study emphasizes the importance of building SOCs in accordance with the requirements of future societies. This study primarily aims to suggest business opportunities created by achieving SDGs, by analyzing business cases involving 3D printing-based construction. Implementing living SOCs through ingenious thinking will not only create new businesses and jobs through digital transformation, but also improve the economic and social value by encouraging community members to be proud of their future society.

"Master Plan of Cadastral Resurvey Project" aims to put the governmental budget of 1.3 trillion Won into the cadastral resurvey project until 2030 that reflects the preliminary feasibility study, conducted by government at 2012. The cadastral Resurvey, which takes 78.8% of the expenses in the project, has to take an critical role for earning the most effective results from the project. The cadastral confirmation surveying take up almost 13% of the project and is controlled under the areal SOC(Social Overhead Capital) projects in current "Master Plan of Cadastral Resurvey Project". Also, the affiliations of cadastral resurvey and linear SOC projects are expected to bring advanced results, although those are excluded from cadastral confirmation surveying. For linear SOC projects, the land division survey is conducted by using boundary stakes in boundary survey, while the cadastral resurvey is conducted within the SOC project area, after the completion of the project. In this study, we could conclude that cadastral resurvey results with the world geodetic system from boundary survey at the point of land division could be produced without the duplication of land division and cadastral resurvey. As a result, the expected benefits are 73,877 parcels and 4,078 million won, annually.
