This research The main focus of this research is to provide basic data for concrete recreation planning of future site by selecting Gwangmyeong-Siheung housing district, large residential development district focused on rural areas, by evaluation of recreation value and detailed biotope type classification. The main results of analysis are as follows. As a result of basic survey of the research area, total 79 family and 307 taxonomic groups are identified and also naturalization index and urbanization index were estimated 16.6 % and 17.6% respectively. Also, as a result of biotope type classification, it is divide into 12 biotope type gorups including forest biotope type group and its subordinate 53 biotop types. As a result of first value evaluation, there are total 13 biotope types such as vegetation-full artificial rivers in I grade. In addition it is analyzed as 9 types of II grade, 5 types of III grade, 8 types of IV grade, 18 types of V grade. Lastly, as a result of second evauation, it is analyzed that there are 21 special meaningful areas for recreation and natural experience(1a, 1b), and 50 meaningful areas for recreation and natural experience(2a, 2b, 2c). It is regarded that the results of biotope types classification and recreation value from this research play roles of analyzing the Suitable site for recreation area before development in terms of large residential development district, and then these results provide important basic data to secure recreational and natural experience area in development planning.

본 연구의 목적은 전원주택단지 수요자들의 입주선호요인을 파악하여 부산지역에 적절한 전원주택단지의 수요촉진방안을 찾아보는데 있다. 실증분석을 통하여 전원주택단지는 시장수요에 근거한 커뮤니티에 초점이 두어져야 하고, 도시근교에 편의시설과 인접한곳에 위치해야하며, 공동체시설이 적용되어야한다는 결론을 얻었다.

In this study the spatial distribution characters of forest in forest damaged area were first considered by analyzing spatial data and monitoring forest landscape. Then suitable tree species on each site were selected through the weighted score analysis of GIS analysis methods. Finally, the best forest stand arrangement method could be presented on the 3D based simulation system for the advanced reforestation technology in Korea. For this purpose, the virtual reforestation system was implemented by using the concept of virtual GIS and CBD (Component Based Development) method. By use of this system the change offorest landscape of burnt forest area some years after reforestation practice could be detected and monitored by applying the site index and 3D modeling method.

The stability study on the rock slope where have produced failures in Boryung dam site was evaluated using the streonet analysis techniques. SMR(Slope Mass Rating) approach which is suitable for preliminary assessment of slope stability in rock was also carried out for rating rock mass. The 3-4 major discontinuity sets are distributed and all type of failure(plane, wedge and toppling failure) are presented in this slope face. The dip of slope must be lowered to friction angle(26degree), otherwise the possibility of plane and toppling faiue will always exist in this slope.

This study aimed to adaptive reuse plan a take advantage of Suncheon Bay Garden Expo 2013. Detailed objectives included: to identify and foster cultural and ecological resources in Suncheon Bay and Garden Expo Site; and to search and propose characterized program in the site for efficient utilization; and to revitalize a site for the vitalizations of the region where garden culture and garden industries for strengthening local competitiveness. The study was multi-phased. The first stage included basic surveys such as site status and environmental context analysis, and questionnaires and similar case studies, and the second stage was to review the direction of preliminary planning, develop associated industries and strategies for regional revitalization and review and incorporate project details. And the third stage aimed to develop a comprehensive plan from spatial plans and program plans and suggest plans to vitalize the operation of the site. The results of the study are as follows: First, the characterization strategy is 'healing experience tourism', 'healing garden', 'healing herbal care' are suitable for the site and regional revitalization. Second, the dimension of 2013 Suncheon Bay Garden Expo which was distinguished into four areas, in consideration of the characteristics and contents of the garden expo site for efficient operation and maintenance. Four area are as follows: the park oriented area, the experiential tourism oriented area, the existing conservation oriented area, and the area for associated industries. Third, the practice of private and public partnerships is needed in order to efficiently manage and operations. The significance of this study is that it is seeking to take advantage of the Garden Expo site and set the plan by existing resources and in consideration of local characteristics, in conjunction with area to envision and proposed management plan. Some problems are remained which have not been able to deal with details program and organization and financial planning programs for the operation of the site. This is for further study.

The spiral case concrete (SCC) used in the underground powerhouse of large hydropower stations is complex, difficult to pour, and has high requirements for temperature control and crack prevention. In this study, based on the closed-loop control theory of "multi-source sensing, real analysis, and intelligent control", a new intelligent cooling control system (ICCS) suitable for the SCC is developed and is further applied to the Wudongde large-scale underground powerhouse. By employing the site monitoring data, numerical simulation, and field investigation, the temperature control quality of the SCC is evaluated. The results show that the target temperature control curve can be accurately tracked, and the temperature control indicators such as the maximum temperature can meet the design requirements by adopting the ICCS. Moreover, the numerical results and site investigation indicate that a safety factor of the spiral case structure was sure, and no cracking was found in the concrete blocks, by which the effectiveness of the system for improving the quality of temperature control of the SCC is verified. Finally, an intelligent cooling control procedure suitable for the SCC is proposed, which can provide a reference for improving the design and construction level for similar projects.

대규모 해상풍력단지 개발을 위한 입지 적합성을 효과적으로 확보하기 위해서는 개발로 인한 환경영향을 최소화하고 사회적·생태적·경제적 핵심가치에 대한 편익 상충에 대한 분석이 필수적이다. 또한 해양공간계획상 타 용도구역과 충돌하지 않도록 입지 적정성에 대한 사전검토가 반드시 선행되어야 하며, 추가로 전남 해역 인근의 풍력자원을 포함한 국지적인 기상 특성 분석도 사업타당성 조사 이전에 수행되어야 할 필요가 있다. 이에 영광군 안마도 인근 왕등여에 설치된 기상탑의 관측자료를 활용하여 풍력자원분석을 수행하였고, 해상풍력 단지 입지 관련 지리적 제약조건을 배제한 후 최적 입지구역을 선정하였다. 또한, 국지적 풍력자원 특성에 적합한 풍력단지 최적배치 결과를 WindSim 기반으로 도출하여 연간발전량을 산출하였으며, 향후 해상풍력 프로젝트의 입지발굴 및 적합지 선정에 기초연구자료로 활용하고자 한다.

Traditional investigation procedures of soil and groundwater contamination are followed by soil gas sampling, soil sampling, groundwater sampling, establishment of monitoring wells, and groundwater monitoring. It often takes several weeks to obtain the analysis reports, and sometimes, it needs supplemental sampling and analysis to delineate the polluted area. Laser induced fluorescence (LIF) system is designed for the detection of free-phase petroleum pollutants, and it is suitable for on-site real-time site investigation when coupling with a direct push testing tool. Petroleum products always contain polycyclic aromatic hydrocarbon (PAH) compounds possessing fluorescence characteristics that make them detectable through LIF detection. In this study, LIF spectroscopy of 5 major fuel products was conducted to establish the databank of LIF fluorescence characteristic spectra, including gasoline, diesel, jet fuel, marine fuel and low-sulfur fuel. Multivariate statistical tools were also applied to distinguish LIF fluorescence characteristic spectra among the mixtures of selected fuel products. This study successfully demonstrated the feasibility of identifying fuel species based on LIF characteristic fluorescence spectra, also LIF seemed to be uncovered its powerful ability of tracing underground petroleum leakages.
