양방향 전력정보 교환을 통하여 합리적 에너지 소비를 유도하고, 고품질의 에너지 및 다양한 부가서비스를 제공하며, 산업간 융 복합을 통한 새로운 사업모델을 창출하고자 스마트그리드 확산사업이 진행되고 있다. 또한, 스마트그리드 확산사업을 통해 에너지 사용절감, 전력피크완화, 온실가스 배출 감소 등의 목표가 대두되고 있으며, 스마트그리드 확산사업으로 인해 사회적 후생이 얼마나 증가하는지에 대한 편익분석이 필요하다. 본 논문에서는 스마트그리드 확산사업 편익의 구성요소를 파악하여, 실제 사례에 대한 데이터를 분석해 보았다.

Currently, the government has been driving numerous projects to build the e-government which can enable limitless access and utilization of the information through the accomplishment of the real time based various administrative services. In water resource field, a project to generate digital river thematic maps has been undergoing as a part of the computerization projects. As a partial results, the RIMGIS project has been completed and generation of the various river thematic maps has been required to fully utilize the DB built from RIMGIS project. For the effective generation of the thematic maps, a data model needs to be developed. A data model has been developed in this study to provide more efficient method to generate the thematic maps utilizing existing DB. The data model proposed from this study has defined the relationships between core feature data and framework Data along with relationships among data elements to represent the rivers in the real world more accurately. The core feature data and framework layers have been defined based on the survey of the domestic and foreign case studies along with requirement analysis of the users in the water resource field. The proposed core feature data has been defined based on the minimum unit of 'class', and the relationship between classes has been established based on the ArcGIS Hydro Data Model for the integrated processing of the river information. The proposed spatial data model can be judged to contribute establishing more efficient generation methodology of the river thematic maps.

The research objectives investigates main research topics and trends in the information and communication technology(ICT) field, Korea using LDA(Latent Dirichlet Allocation), one of the topic modeling techniques. The experimental dataset of ICT research and development(R&D) project of 5,200 was acquired through matching with the EZone system of IITP after downloading R&D project dataset from NTIS(National Science and Technology Information Service) during recent five years. Consequently, our finding was that the majority research topics were found as intelligent information technologies such as AI, big data, and IoT, and the main research trends was hyper realistic media. Finally, it is expected that the research results of topic modeling on the national R&D foundation dataset become the powerful information about establishment of planning and strategy of future's research and development in the ICT field.

최근 4대강 사업이 진행되면서 하천의 보가 설치되고 있다. 하지만 이러한 구조물은 수체 거동의 특성을 변화시키며, 수질의 분포 또한 일반 하천과는 다른 특성을 지니게 된다. 흐름 방향보다 수심 방향으로의 특성이 강하게 작용하는 저수지 형태의 하천에서는 1, 2차원적 모델의 적용에서 벗어나 3차원 수리 수질 모델링을 적용함으로써 하천과 다른 특성을 반영한 모델을 구축해야 한다. 따라서 본 논문에서는 4대강 사업에 따른 보 설치로 인한 금강 수계 일부 구간을 대상구간으로 선택하였으며 EFDC(Environmental Fluid Dynamics Code)의 수리헉적 부분과 조류중심의 해석 구조를 지닌 WASP(Water Quality Analysis Simulation Program)의 수질부분을 연계하여 하나의 모델로 구축하여 보설치에 따른 수질변화를 모의하였다.

U-City는 도시에 IT를 접목하여 도시의 운영과 관리를 효율화하고 다양한 서비스의 도입을 통해 주민들의 복지 향상을 목적으로 하는 신개념의 도시이다. UMC(U-City Management Center)는 U-City의 핵심요소로 U-City의 각종 서비스의 관리 운영을 통제하고, 새로운 부가가치를 생성하는 역할을 한다. 하지만 정보화 사업을 타당성 분석없이 진행하는 경우 전반적인 재정의 운영이라는 정책적인 측면에서 문제가 발생할 소지가 크다. 따라서 UMC 타당성 분석이 선행되어야 한다. 본 논문에서는 정보화사업의 타당성 분석을 위한 선행연구들을 분석하고, UMC의 타당성 분석을 위하여 AHP 모델을 적용하였다. 또한 도출된 모델을 이용하여 구축중인 UMC의 타당성을 분석하였으며, 분석 결과 기술적 타당성, 경제적 타당성, 정책적 타당성 중 기술적 타당성이 가장 낮은 것으로 평가되어 향후 기술적 문제를 보완해야함을 도출하였다.

The Clean Development Mechanism (CDM) is the multi-lateral 'cap and trade' system endorsed by the Kyoto Protocol. CDM allows developed (Annex I) countries to buy CER credits from New and Renewable (NE) projects of non-Annex countries, to meet their carbon reduction requirements. This in effect subsidizes and promotes NE projects in developing countries, ultimately reducing global greenhouse gases (GHG). To be registered as a CDM project, the project must prove 'additionality,' which depends on numerous factors including the adopted technology, baseline methodology, emission reductions, and the project's internal rate of return. This makes it difficult to determine ex ante a project's acceptance as a CDM approved project, and entails sunk costs and even project cancellation to its project stakeholders. Focusing on hydro power projects and employing UNFCCC public data, this research developed a prediction model using logistic regression and CART to determine the likelihood of approval as a CDM project. The AUC for the logistic regression and CART model was 0.7674 and 0.7231 respectively, which proves the model's prediction accuracy. More importantly, results indicate that the emission reduction amount, MW per hour, investment/Emission as crucial variables, whereas the baseline methodology and technology types were insignificant. This demonstrates that at least for hydro power projects, the specific technology is not as important as the amount of emission reductions and relatively small scale projects and investment to carbon reduction ratios.

The Ministry of Strategy and Finance of South Korea accesses public organizations annually for increasing outcomes with effective and clear managements. The management assessment is categorized into the business management applied all organizations and the main business assessed by purposes and characters of organizations. This study analyzes metrical indexes of main businesses with using the logic model and suggests the direction of developing metrical indexes of organizations. Metrical indexes of the Korea Land and Geospatial Informatix Corporation in 2017 were analyzed to develop indexes. The results indicates that metrical indexes of the Korea Land and Geospatial Informatix Corporation are mainly consisted of the commitment and process. The logic model was suggested to analyze proprieties of metrical indexes of the main business. This study shows that organizations develop metrical indexes of the main business with classifying that these are from calculation indexes or result indexes. Thus, this study suggests that organizations consider result indexes based on the logic model for developing metrical indexes of the main business.

After the revision of Private Investment Law in January 2005, BTL is introduced to expand the social infrastructures as a major business procedure. Especially, the size of the public educational infrastructure ordered by each city education office is increased by 45% compared to last year, so it is major in BTL Project. However, in the process of practicing BTL Project by now, there are a lot of problems specially in the public educational infrastructure. As a result, this study gives the solutions in the process of BTL Project, the CM models to support the Education Office${\square}{\square}$job and the suggestions for the working scope of the participating construction companies.
