In this study, the plausible grid size was estimated to increase for efficiency of reservoir management using 3 dimensional water quality model. To validate utilization of a real time water quality management tool, ELCOM-CAEDYM model was applied to Soyang reservoir in korea. 100m grid size can represent the real topography and take out exact analysis results. $400{\times}400m$ grid can be easily used to analysis because of data capacity. Consequently, the grid size of 200m or 300m was recommended to establish 3D model considering the required simulation time and the irrelevance between horizontal grid size and vertical distribution for temperature and turbidity analysis.

The development in the design process is usually based on the choice of a method for designing the system, in which this method is frequently faced with tightening environmental requirements, reducing development cycle times and growing complexity. To tackle such factors, the paper proposes a comprehensive approach focusing on applying systems engineering approach to the building design support. In particular, this paper addresses all capabilities of using some available systems engineering standards (like EIA-632) in the design process. Then, a methodological approach is proposed for the practice of requirements engineering by applying quality assessment and control to design in early phase. The paradigm used, here is to extend and particularly to adapt the work carried out in military and space systems to modern building services by taking into account the semantics of buildings in terms of different engineering fields and architecture issues.

The Ministry of Environment, Ministry of Agriculture, Fishery and Forestry, and Ministry of Construction, Transportation and Maritime Affairs are in charge of livestock manure management. There are national statistics regarding the livestock industry such as the National Pollution Source Survey, Livestock Statistic Survey, and Livestock-breeding Trend Survey. The current statistical data are focused on the scale of livestock breeding and the production of livestock manure using these data, but it is difficult to establish database due to lack of information. In order to plan relevant policies including management of livestock manure, the government established database systems such as the integrated information system of livestock manure, the integrated system of national infectious animal-disease prevention, and the Sae-ol public administrative system. We have tried to suggest improvements for the comprehensive environmental information system of livestock manure management by detecting problems in each level of the livestock manure life-cycle, making use of the existing systems, and considering the electronic transfer system of livestock manure. The services and functions of this comprehensive system include information of livestock farmers, the production, collection, transportation, and treatment of livestock manure, the area of agricultural land used for livestock manure, the report of approval and results on livestock manure products, management of statistical information, management of civil affairs, and relevant mobile application services. The system is made up of three processes: first, establishment of GIS-based management database of livestock manure; second, establishment of a history management system for livestock manure transactions; and third, development of a water quality assessment system.

Ecotourism has been attracting much attention as an example industry that can vitalize local economy markets and preserve natural resources. Implementation of 'Ecotourism Designation System' is under consideration to provide ecotourism products that can both emphasize the original meanings of ecotourism and ensure stronger trust from customers than ever before. This research introduced the direction, principles, subjects, and assessment indicators by subjects in terms of implementing the system and proposed fundamentals for both designation assignment and score calculation. In the face of implementing such a system in Korea, the investigation sought subjects whose target areas and programs are in need of examination. For assessment criteria by subjects, six assessment indicators were selected in the end for ecotourism sites, including: (1) the value of natural/ecological preservation (2) facility's ecological design (3) understanding both the environment and local culture (4) systems connecting local communities for cooperation (5) long/short term preservation and maintenance strategies/plans (6) willingness to further develop ecotourism and cooperative platform. In addition, seven assessment indicators were selected for program assignments, including: (1) the value of natural/ecological preservation (2) minimization of environmental effects (3) expansion of environmental understanding (4) sharing the local culture (5) vitalizing local connections and economical activities among communities (6) securing and maintaining professionality among human resources (7) odds of continuation, creativity, and aptness to improve programs. After considering the pros and cons of both categorizing system and yes/no system, implementation of categorizing system for the short term and yes/no for the long term were suggested, followed by additional suggestions of a score calculation system for each system. The official implementation of the 'Ecotourism Designation System' is scheduled for launch in 2013 after the trial operation in 2012. The assessment indicators and fundamentals suggested in this research, considering judgment, must be improved via systematic and practical methods through the trial operation.

Post-kyoto regime has been discussing with the GHG reduction commitment. GHG energy target management system also has been applied for the domestic measures in the country. Universities are major emission sources for GHG. It is very important for campus to built the GHG inventory system and estimate the potential GHG emission reduction. In general, GHG inventory on the campus was taken by the IPCC guidance with the classification of scope 1, 2, and 3. Electricity was the highest portion of GHG emission on the campus as 5,053.90 $tonsCO_2eq/yr$ in 2009. Manufacturing sector was the second high emission and meant GHG in laboratory. Potential GHG reduction was planned by several assumptions such as installation of occupancy sensor, exchanging LED lamp and photovoltaic power generation. These reduction scenarios was simulated by LEAP model. In 2020, outlook of GHG emission was estimated by 17,435.98 tons of $CO_2$ without any plans of reduction. If the reduction scenarios was applied in 2020, GHG emission would be 16,507.60 tons of $CO_2$ as 5.3% potential reduction.

This study was conducted based on the 115 development projects of residential areas during 2001-2006 to investigate the current status of park green areas. Prior Environmental Review System (PERS) was categorized into regions, scales, and time of the projects, and regression model was used for a statistical analysis. The ratios of greenness of Seoul and Gyunggi province were greater than those of other regions whereas the ratios of greeness of Cheonnam, Chungbuk, and Jeonbuk provinces showed smaller percentage of green areas. Secondly as the scales of development get bigger areas of greenness become larger indicating a large scale residential development projects are favorable for securing green areas. Thirdly the correlation between planned area and green areas, and that between planned population and the ratio of greenness are relatively low (P>0.05). This implies green areas are not a good indicator but a concrete guideline for green areas. Fourthly the ratio of greenness of small scale project is not reached to 10% so that it is recommended to secure over one million $m^2$ areas for development project.

The purpose of this study is to work out strategy for utilization of Environmental Conservation Value Assessment Map (ECVAM) using the user survey. It surveyed system users of ECVAM about its recognition and satisfaction. The results of the survey, the ECVAM became more popular and were highly satisfied with updated data. Especially, the study found a relationship between the satisfaction of ECVAM and accuracy, utilization, and convenience of the system. However, the satisfaction has a difference between user groups, a government official and a agent for EIA including researchers. The satisfaction of the agent group was affected by the convenience, the accuracy, and the utilization in order. In the other hand, the satisfaction of the government official group was affected by the utilization, the convenience, the accuracy, and recognition in order. Therefore, we need to adopt different strategies for educations of ECVAM and publicity activities depending on user groups. To increase the satisfaction of ECVAM, we should research not only to attain pinpoint accuracy, but also to suggest the guideline to utilize the map for a government official.

현존하는 셀룰라 이동통신의 가입자 수용 한계로 부호분할다원접속(CDMA) 방식을 사용하는 디지틀셀룰라 통신 방식이 거론되고 있다. EIA/TIA 잠정 표준안인 CDMA 시스팀에서는 동일한 확살부호를 전체 시스팀에 사용하지만 각 기지국에 확산부호의 위상옵셉(phase-offset)을 다르게 배분함으로써 이동국은 기지국으로 송신된 신호를 구변하도록 하고 있다. 그러나 확산부호의 위상옵셉이 기준이 되는 영옵셉(zero-offset) 부호를 임의로 설정하고 있다. 본 논문은 확산부호의 기준 부호를 정하는 방법을 제시하고, 기준 부호로부터 위상을 이전(shift) 시킨 부호 사이의 위상옵셉을 쉽게 계산하는 방법을 제시한다.

최근 들어 택지개발사업이 크게 증가하는 추세이지만, 무분별한 택지개발은 개발대상 부지의 기존 녹지나 수목을 훼손시키게 되며 지형에도 많은 변화를 가져와 절개지가 발생하게 하는 등 환경을 많이 훼손하고 있다. 택지개발 등 개발사업을 시행할 때 지구지정시 수행하는 사전환경성검토제도와 개발계획의 승인전 협의를 하게 되어 있는 환경영향평가제도가 있다. 사전환경성검토는 택지개발계획 수립 후에 시행하며 환경영향평가는 실시설계 완료 후에 수행하기 때문에 선정된 택지개발지에서 발생할 수 있는 환경문제에 대한 저감방안 강구 등 소극적이고 수동적인 대처에 그치는 경우가 많다. 본 논문의 목적은 초기 입지선정단계에서 택지개발사업을 환경친화적으로 지속가능하게 수행할 수 있도록 대안평가모형을 구축하는 것이다. 이를 위해 선행연구에서 조사된 택지개발사업의 환경평가요인을 바탕으로 퍼지추론과 AHP기법을 이용하여 대안평가 모형을 구축하였다. 의사결정자가 각 대안의 환경훼손도를 10점 척도법에 의해 평가하면 퍼지추론에 의해 환경성능(EP: Environmental Performance)으로 변환하고, AHP기법에 의해 미리 산정된 항목별 가중치를 적용하여 통합환경성능(TEP: Total Environmental Performance)을 산정한다. 통합환경성능이 가장 높은 대안이 최적안으로 선택된다. 이 연구에서 제시한 평가방법을 적용하면 토지이용계획이 확정되지 않은 상태에서 두 가지 이상의 택지개발 예정지역 대안을 정량적으로 평가할 수 있을 것이다. 이로써 택지개발 사업시행으로 발생할 수 있는 환경훼손을 초기 입지단계에서 확인하여 환경오염을 원천적으로 제거해 나갈 수 있을 것이다.
