Recently public institutions' debt is growing therefore it became an important issue to the level that the government concerns about the possibility of financial burden to reduce the debt. Especially debt of public enterprises in metropolitan areas was in a serious state where debt in late 2013 was 43.2 trillion, which takes approx. 58.4% of 73.9 trillion of debt of all local public enterprises. Sound financial state of local public enterprises is important to public enterprises in metropolitan areas and it may affect seriously financial stability of local governments when public enterprises have financial problems. However, land supply business to form local industrial complexes or local demand for development of public rental housing business always exist; and vitalizing local economy and creating jobs through these businesses are very necessary to develop the areas. However, for local economic development, industirial land business and public rental housing business are needed. In this study, Gwangju Metropolitan City Corporation Ltd is used as a case study to evaluate the local public financial soundness via debt management assessment i.e.(using) the feasibility analysis in the urban development and housing development. As an improvement measure following the result of analysis, for the enhancement of financial soundness of urban innovation corporation, the government and local government shall evaluate and differentiate market demand, price competitiveness, and infrastructure of new town land development project to improve accuracy of project feasibility analysis. Another important insight is that there should be local government-centered management of liabilities of the local government and local public enterprises with the integrated liability management system to reduce the liability of the corporation and solve the issue of debts for local government. This study is significant in that it has analyzed cases from the theoretical aspect to secure financial soundness of national and local public enterprises.

Interests in clean fuels have been soaring because of environmental problems such as air pollution and global warming. Unlike fossil fuels, hydrogen obtains public attention as a eco-friendly energy source because it releases only water when burned. Various policy efforts have been made to establish a hydrogen based transportation network. The station that supplies hydrogen to hydrogen-powered trucks is essential for building the hydrogen based logistics system. Thus, determining the optimal location of refueling stations is an important topic in the network. Although previous studies have mostly applied optimization based methodologies, this paper adopts machine learning to review spatial attributes of candidate locations in selecting the optimal position of the refueling stations. Machine learning shows outstanding performance in various fields. However, it has not yet applied to an optimal location selection problem of hydrogen refueling stations. Therefore, several machine learning models are applied and compared in performance by setting variables relevant to the location of highway rest areas and random points on a highway. The results show that Random Forest model is superior in terms of F1-score. We believe that this work can be a starting point to utilize machine learning based methods as the preliminary review for the optimal sites of the stations before the optimization applies.

With rapid advancements taking place in the Fourth Industrial Revolution, human-robot interactions have been garnering increasing attention. Robots are being actively adopted in building systems and facilities. In this study, we developed robot-friendly building certification indicators. Because these indicators were being developed for the first time, we focused only on commercial buildings. We conducted exploratory research using methodologies such as focus group interviews and the analytic hierarchy process. First, the concept of the robot-friendly building was defined through focus group interviews, and the requirements were categorized by the appropriateness of operating facilities and systems and the appropriateness of architectural and robot operating systems and networks. Next, the relative importance of the evaluation items (23 items in total) was calculated using the analytic hierarchy process. Their average score of the marks was 4.4, and the minimum and maximum were 2.0 and 11.3, respectively. This study is significant because we collected the basic data necessary to develop a one-of-its-kind evaluation system for certifying the robot-friendliness of buildings using scientific methods.

This study proposes a legal limit from the administrative and management standpoint of the city hall/county office/gu office, which is the cadastral authority, in relation to the discrepancy between the actual land use status and the cadastral study that has been continuously raised. And also, from the point of view of civil complaints such as landowners, this study tried to evaluate the practical problems of the current land category system from the point of view of civil complaints such as landowners and to derive a solution to these problems. Therefore, this study indicates how the category of land use is classified, and how land use is restricted by the laws of Registration & Management of public cadastre. Also, it shows the reasons why discrepancy between the land use fixed by the law and the current state of actual use of land occurs. Addtionally, This study suggests a plan to reorganize the Land Category system and it includes consolidation and subdivision of land. The study also describes a way to minimize the targets for conversion of land under control of Land Category System as well as to improve the law that protects the people's property rights.

AVIs on the road are installed for (1) security (2) and for traffic, and they are various managed by (1) police department, (2) local government, (3) national highway management, (4) Korean highway corporation. But although the collected data of the plate number, the travel time, the picture of the car are same, they are used in purposes of its installation because the managements are different and the data are difficult to be connected with each other. For this reason, this study is to appraise the application for creating traffic information by integrating these data, and to suggest the introduction of spatial detection system which integrated security-traffic AVI DB for the purpose of reliability improvement of center's velocity. The estimating sections of link travel information seems to be expanded, and the error rate between the center's velocity and the experimental value will be reduced if integrated DB of traffic and security AVIs is used for creating traffic information. Also, the crime prevention and arrest rate is expected to rise in the future.

물 수요 및 공급 체계를 바탕으로 수급 상황에 대한 판단을 위해 일반적으로 물수지 분석을 이용하고 있다. 물 수급 체계를 기반으로 하는 물수지 분석은 분석 대상유역의 물 수요를 고려하여 공급 가능량을 판단한 후 두 가지 인자 간 상호 비교를 통해 물 부족 여부를 판단하는 과정이라 할 수 있으며, 가장 대표적인 사례는 수자원장기종합계획에서의 물 수급 전망 분석 과정이라 할 수 있다. 수자원장기종합계획의 물 수급 전망에서는 미래 우리나라에서 예상되는 물 수요를 예측하고 수문조건에 따른 공급 상황과의 비교 검토를 통해 시공간적 물 부족 현황을 제시하고 있다. 수자원장기종합계획에서는 공급량 조건을 검토하기 위한 방법으로 기상청, 국토해양부, 한국수자원공사 등 다양한 기관에서 관측된 강우자료를 강우-유출모형에 적용한 후 산정된 자연유출량을 기반으로 물수지 분석을 수행하고 있다. 수자원장기종합계획과 같이 미래 우리나라의 물 수급 상황을 분석하고 이를 바탕으로 제시된 시공간적 물 부족 정보의 신뢰성을 높이기 위해서는 기본적으로 지역 또는 유역별 강우 발생 특성에 대한 정확한 고려가 기반이 되어야 한다. 그러나 현재 수자원장기종합계획 수립 과정에서 이용하고 있는 강우 관측지점의 공간적 분포를 살펴보면, 도서 및 해안지역의 경우 관측소의 밀도가 상대적으로 매우 빈약한 한계를 포함하고 있으며, 대부분 내륙 지역에 관측소가 집중된 현상을 보이고 있다. 이와 같은 상황에서 강우 관측자료를 이용한 분석을 수행할 경우 도서 및 해안지역에 대한 강우 발생 특성의 정확한 반영이 어려울 수 있으며, 이는 물 부족 분석 결과의 정확도 측면에서도 문제점으로 지적될 수 있다. 이러한 한계를 극복하기 위한 방안으로 기상청에서 운영 중인 자동기상관측지점(Automated Weather Station, AWS)의 관측자료를 이용하는 방안을 검토해볼 수 있다. AWS 지점은 내륙 및 도서 해안지역에 관계없이 고른 관측소 분포를 보이고 있으므로 이를 고려할 경우 기존 관측지점에서 한계로 지적된 부분을 충분히 극복할 수 있을 것으로 판단된다. 따라서 본 연구에서는 기상청에서 생산되고 있는 AWS 관측자료를 수집한 후 이를 수자원장기종합계획의 물수지 분석과 동일한 분석 과정에 적용하였으며, 그 결과에 대한 검토를 통해 국가 수자원계획의 신뢰도를 높일 수 있는 방안을 제시하였다.

In this article, legislational and economic meaning of Marine Pollution Prevention Law (MPPL) of North Korea was studied with review and comparison of North Korea's environmental legislation system. North Korea's MPPL is the basic legislation system against pollution activities. This law has the purpose of gaining of marine environmental protection and resources and declares mainly the marine environmental protection with little definition of action plan and means. To analyze economic achievements of MPPL, more macro- and microeconomic data of North Korea should be accumulated. However, environmental issues are relatively effective to discuss common goal of environmental protection and economical cooperation between Korea and North Korea. To prepare reunification, understanding of North Korea's MPPL is the first step for collaboration of marine environmental conservation.

Climate change has emerged as a social issue, and efforts have been made to overcome it in various ways. However, climate change due to global warming is likely to accelerate further than we expected, and the associated damage is also likely to increase. This tendency is expected to continue in the future, leading to difficulties for the existing water resource management system based on historical data. The precipitation in 2020 caused property damage and loss of life due to the extreme rainfall exceeding the design rainfall with the very unusual prolonged rainy days. With this 2020 flood, we should no longer be passive in managing flood risk due to uncertainties in climate change.

After the terrorist attack of 9/11 on the USA, the security concern to global trade has been raised. In particular, the USA has actively promoted a series of initiatives and rules such as CSI, 24 hour rule, C-TPAT, and so on in the area of logistics activities, which aimed to better protect the country against the potential terrorist threats. While implementing such schemes called as a multi-layed logistics security strategy, a large number of countries trading with USA are facing with the issues of additional time and costs for inspecting cargos in their logistics facilities. As a result, most countries all over the world have sought a way to minimize the impacts from such strategy. The Korea also is preparing the several security programs operated by various ministries, which are aiming to not only improve the efficiency of trade flows but also to ensure supply chain security. However, many companies are expressing the inefficiency of operating such programs. Thus, this paper analyzed several global supply chain security programs currently adopted by international organizations(ISO, WCO, and IMO) and major countries(USA, EU, and Singapore) and suggested a guideline for developing the national logistics security system.
