This study aims to develop a guideline of environmental assessment for tidal current energy development in Korea. Based on an extensive discussion of the environmental effects of tidal current energy, this study provides an appropriate guideline for environmental assessment on tidal current energy development in Korea. The guideline includes a method for proper site selection and specific techniques for environmental impact assessment. The guideline for environmental impact assessment consists of four steps - including current condition investigation, impact predictions, identification and incorporation of mitigation measures, and post environmental monitoring - to effectively predict and assess impacts of tidal current energy development on the ocean environment. It is expected that the guideline can facilitate the often demanding environmental assessment review process and to reduce the time taken for it.

Since the weapon system project has a large ripple effect on the country by investing a huge budget, analysis of acquisition methods that secured economic feasibility is required in the planning stage to promote the weapon acquisition project. In response to this demand, economic analysis for acquisition method is preformed in the research stage of previous studies, but the analysis on economic analysis for acquisition alternative is imperfect at the present. In this research, we identify the limitations of the effect analysis and propose an additional cost-benefit analysis method to analyze the economic feasibility of the acquisition alternative. It is possible to present the universal results of economic feasibility analysis for not only multiple alternatives but also single alternatives by presenting benefit/cost ratio. It is applied to research on acquisition project of OO guided rocket, and the result of economic analysis for each alternative is presented.

The objective of this paper is to provide an approximate cost estimating model for tunnel that can be utilized both in quick construction cost estimating for design alternatives, and in evaluating efficiently the cost effects according to the environmental changes during design and construction stage. To meet this requirement, this study analyzes critical cost factors influencing tunnel construction costs. The cost factors include 7 elements such as rock drilling method, advancing method, type of detonator, loader capacity, unit weight and soil volume change factor, length of tunnel. This paper investigates the cost variance according to the change of the cost factors. The result is expected to be used in formulating approximate tunnel cost estimating model.

Korea Hydrographic and Oceanographic Agency(KHOA) carried out a research project named 'Marine Fisheries Infrastructure Construction and Technology Training for the Philippines' as part of the 1st Official Development Assistance(ODA) from 2015 to 2018. It is preparing for the 2nd ODA project which will begin in 2020. Besides, recently, the Philippines is paying attention to marine territory management and response capability due to problems such as the sea-level rise and coastal erosion caused by climate change. Therefore, before 2nd ODA to the Philippines, this study analyzed the vertical ocean model on the vertical datum in Korea and suggests the direction of development of the vertical ocean modeling system for the vertical datum in the Philippines using the observed data from the permanent tide station which was built by the Philippines ODA research project over the last four years. Moreover, as a pilot study, the Sulu Sea in the Philippines was selected and analyzed by harmonic analysis method. At each tide station, constants for correction had been computed. And the grid-based tidal model was constructed based on this study. As a result of the study, similar tidal characteristic were observed when the prediction and the measured tide were compared by applying the constants for correction between two station in the sea area with similar tidal level. These results could be used as basic data for the 2nd ODA to the Philippines, and contributed to construct and maintain a close cooperation and friendship between Korea and the Philippines.

지금까지의 전력산업은 민간자본이 부족한 상태에서 경제개발에 필요한 전력수요를 충당하기 위하여 1960년대 이후 지금까지 약 40년 동안 전원개발사업을 수행하여 왔다. 그러나, 이제 우리나라는 경제 개발기를 벗어나서 급속한 경제성장보다는 안정적인 경제여건 마련과 산업구조의 개선을 통해 선진국으로 진입하기 위한 준비가 필요한 단계로서 전력도 더이상 국가에서 싼 값으로 제공하는 소비자가 정당한 값을 주고 구입하여야 하는 시점에 이르렀다.

Inadequate cost management has widely been recognized as one of the most problematic areas in the Korean construction industry as many believes that public cost references are not reasonably reflecting the market conditions. 'Total Project Cost Management Guideline' developed by Ministry of Economy and Finance(MOEF) to govern public budget control has been identified as one of the main reasons for this problem. This study attempts to thoroughly review 'Total Project Cost Management Guideline' itself and quantitatively analyze the impact of it on project cost during procurement process. Different procurement methods are considered including turnkey & alternative, private contract, qualification examination, and lowest price bidding system in this quantitative impact analysis of 'Total Project Cost Management Guideline'. Analysis results shows that this governmental process works mainly as a constant cost-cutting tool throughout the procurement process.

Soil and groundwater contamination is an emerging national issue in recognition of the potential adverse impact to human health and ecosystem. In a recent registration, property owner's liability was addressed on the damages to neighbor's soil and groundwater caused by contaminant-plume migration. Soil and groundwater remediation is a technical and engineering project. But, the scientific and technical solutions for the project have been greatly influenced by social and political movement in the country. Governmental sectors, including local and central, should actively engage on this important issue through long-term planning and public investments. Government made regulations to prevent soil and groundwater contamination, not to punish private sector that has no technical and financial capability for solving such problems.

The purposes of the study are to describe the feature of the program components, and to identify their changes in the process of designing the social work programs in the community service agencies in Korea. In order to achieve these purposes, the researchers constructed an analytical framework including 24 program components derived from the related literatures. Data was collected by questionnaires answered by the social workers who were in charge of the program development and implementation. Descriptive statistics analysis and factor analysis were applied to exam the features of the program components in 195 social service programs developed by the funds from the Community Chest of Korea and a private funding foundation. As the result of the analysis, the three noticeable features are found; (1) the agencies have very actively involved in the designing work in the process of developing practice guideline, however they have less involved in the designing work in the process of implementing program; (2) program components which are low level in design activities are intervention models, staff education, and practical ethics; (3) 8 categories of components derived from the theoretical perspective are reduced to 6 categories in the process for developing practice guidelines, finally to 4 categories in the process for implementing the programs. The implications of major findings were discussed in academic and practical perspectives in Korea, including future research works in the area.

오늘날 각국의 전력산업계에서는 발전단가를 경제적으로 유리하도록 낮추고 전력수요에 탄력적으로 대처하며 기존 발전설비를 효율적으로 활용하기 위하여 발전설비의 성능개선 및 발전소 운전 수명 연장 계획을 추진하고 있다. 최신 기술에 의한 제어게통 성능 개선은 이러한 목적을 제한된 예산과 짧은 기간내에 효과적으로 수행할 수 있는 사업으로 고려되고 있다. 근본적으로 고장-내력 기능을 가지고 있는 마이크로프로세서를 이용한 분산 디지탈 제어기술은 대용량의 공정계통을 실시각 성능분석과 예측제어를 가능케 할 뿐만 아니라 다중 제어계통으로 계통의 신뢰도 및 이용율을 높이고 발전소 운전 및 제어를 용이하게 계층적으로 구성시킬 수 있는 최신 제어 기술이다. 이로써, 사례에 밝혀진 바와 같은 제어 설계 개선 및 설비 대체로 발전소 운영의 경제성, 안전성, 신뢰성 및 편이성의 개선 효과를 달성시키고 있음을 알았다. 특히, 선진국의 원자력 발전소의 제어계통 성능개선 사례는 경제성은 물론 안전성 확보에도 큰 기여를 하고 있음이 밝혀졌다. 우리나라도 전력 수요에 경제적으로 대처하고 보다 양질의 전기를 생산하며 기존설비를 효과적으로 이용하기 위하여 현재 추진중에 있는 화력발전소 제어계통 성능 개선을 단계적으로 추진하고 있는 것은 고무적인 계획임에 틀림이 없다 하겠다. 또한, 원자력 발전소의 경우에도 안정성을 제고시키고, 발전소의 이용율을 증대시키기 위하여 추진중인 신기술을 적용한 성능 개선 사업의 단계적 추진은 당연한 추세라 할 수 있다.
