Sustainable development is important because the ultimate objective is efficient development combining the economic, social, and environmental aspects of urban conservation. Despite Korea's rapid urbanization and economic development, the distribution of resources is inefficient, and land-use is not an exception. Land use distribution is difficult, as it requires considering a variety of purposes, whose solutions lie in a multipurpose optimization process. In this study, Yangpyeong-eup, Yangpyeong, Gyeonggi-do, is selected, as the site has ecological balance, is well-preserved, and has the potential to support population increases. Further, we have used the genetic algorithm method, as it helps to evolve solutions for complex spatial problems such as planning and distribution of land use. This study applies change to the way of mutation. With four goals and restrictions of area, spatial objectives, minimizing land use conversion, ecological conservation, maximizing economic profit, restricting area to a specific land use, and setting a fixed area, we developed an optimal planning map. No urban areas at the site needed preservation and the high urban area growth rate coincided with the optimization of purpose and maximization of economic profit. When the minimum point of the fitness score is the convergence point, we found optimization occurred approximately at 1500 generations. The results of this study can support planning at Yangpyeong-eup.ausative relationship between the perception of improving odor regulation and odor acceptance.

The Korean hospitals have been changed a lot from 1970's to 1990's, not only in their space allocation but also in their functions. These changes were affected by the medical development, social atmosphere, increasing population, needs of medical demands, and so on. In this study, we compared net area allocation involve in these affect of hospitals which were built in 1970's, 80's, and 90's, and through this comparison, we analyzed developing tendencies of hospitals. In doing so, we tried to provide basic research data for planning of new hospital buildings.

This dissertation is about a study on the space planning of take-out coffee shops grouped by type. The classification is based primarily on stand-alone shop, which runs independently, and shop in shop, located inside of another shop with different industry. And its subdivision is characterize by 3 types: Combination type has not only space to enjoy coffee as we can usually see in conventional coffee shops, but also a counter where take-out coffee is served. Separation type has space for drinking coffee and an external booth for easy buy. Booth type is a booth itself or driving (cruising) booth. In conclusion, some take-out coffee shop are exampled and space analysis is made with analytic tools, such as people of preference, location evaluation, functional space division, dimension per person, and planning of traffic line.

An analysis to allocate storage space for sediment accumulation during the economic life of the reservoir is required in the planning or design of a reservoir. This analysis has been the most difficult and tedious aspect to deal with reservoir sedimentation because of the interaction between the various parameters related to the hydraulics of flow, reservoir operating policy, inflowing sediment load. The approach to analyzing spatial distribution of deposits has relied on empirical methods, all of which required a great deal of simplification from the actual physical phenomena. For the purpose of this study, reservoir sedimentation rate computed by Empirical Area Reduction Method is compared with measuring rate along the Soyang-gang Dam. As a conclusion, reservoir sedimentation rate can be estimated exactly by Empirical Area Reduction Method.

Hospital architectures, as a function-oriented architecture, have a great influences on the functional program and spacial allocation for a great number of rooms and departments. Particularly, spacial allocating analysis is depends on various external forces, such as hospital-size, relationships for the others, ownerships, operating methods, long-term masterplan as well as researchers' methods. Furthermore, as there is focusing on architectural design basis rather than architectural planning In recent Korean architectural field, adequate analysing methodology of spacial allocation for the design process is needed. This paper analyzes architectural drawings for 8 Korean hospitals which constructed in recent 20 years in aspects of the spacial allocation for inner spaces and then, presents areal composition and pattern of spacial allocation for researching hospitals.

The objectives of this study are to analyze the factors affecting the structural changes of agricultural land use in Gyeongsangnam-do and to prospect for its future use. Seven commodity groups are categorized to include all agricultural products: rice, summer food crops, summer vegetables and other cash crops, fruits, barley, winter field vegetables, and winter greenhouse vegetables. We developed a model for acreage distribution among the seven commodity groups, and estimated the economic relations between prices and acreage distribution. The results showed positive relations exist between cultivating acreage and own commodity prices in all commodity groups, whereas competitive relations exist between summer commodity groups or winter commodity groups such that rice price decreases led to increases of fruits cultivating acreage or vice versa and winter vegetable price increases led to increases of winter greenhouse vegetables cultivating acreage or vice versa. Further, acreage elasticities with respect to own commodity prices or farm wage rates are estimated over the last 30 years, and future agricultural land use in Gyeongsangnam-do is prospected based on three different scenarios. Total agricultural land use in Gyeongsangnam-do will be decreased over the next 10 years from 159,000 ha in year 2010 to 143,000~153,000 ha in year 2020. By commodity group, cultivating acreage of rice, summer food crops, and barley will be decreased while cultivating acreage of summer vegetables, fruits, winter field vegetables, and winter greenhouse vegetables will be stagnant.

Design scheme drawings of the two major corporate hospitals - Asan Medical Center and Samsung Medical Center - are analysed in the aspect of floor area distributions and their proportions for various users and user-functions. Primary users of hospitals are categorized into three ; patients, employees and others. Then, patient spaces are subdivided into patient private, patient/medical, patient/support staff, patient/nursing, patient/guardian, patient common ; employee spaces into doctors, trainees, doctors common, nurses, support staffs, non-medical staffs, employee common ; others spaces into subcontractors, general publics, non-living, and internal circulation. The purpose of this research is to develop a user-focused insight into hospital spaces and a new method of hospital programming and design.

도시개발에 따른 인구증가와 강수의 계절적 편중 등으로 인하여 우리나라의 수자원량은 부족한 실정이다. 따라서 이러한 수자원을 효율적으로 이용하기 위해서는 유역의 가용 수자원량의 파악과 이에 따른 최적배분이 필요하다. 이러한 하천유량은 우량이나 수위와 같이 연속관측이 어렵기 때문에 관측치가 한정되어 있는 것이 일반적이며 자연하천에서 실시간으로 유량자료를 생산하는 것은 많은 인력과 장비, 경비가 필요하게 된다. 따라서 본 연구에서는 유량자료의 생산에 있어서 시간과 비용의 경제성 등을 고려하고 좀 더 효율적인 방법을 찾기 위하여 낙동강 유역의 제 1지류인 금호강 유역 내에 위치한 동촌 수위관측소의 유량자료를 이용하여 상류에 위치한 금호 단포교 지점을 미계측 유역이라 가정한 후 유량추정방법에 따른 적용성 검토를 위해 강우-유출모형인 SWAT(Soil and Water Assessment Tool)과 유역면적만을 활용하는 비유량법(Drainage-area ratio method), 유출에 영향을 주는 지형인자를 이용하는 지역회귀방법(Regional regression method)을 적용하여 그 타당성을 비교하였다. 모의된 결과, 동촌 금호 단포교 지점의 연간 상하류 유량비교에서 유량반전은 없었으며 비유량법의 유량추정에서는 높은 상관성을 보였으나 2008년과 2009년의 가뭄으로 인하여 강우-유출모형의 유량추정에서는 낮은 상관성을 보여주었다. 지역회귀방법에서는 수위관측소별 유황자료를 종속변수로 유역면적, 유역평균경사, 유로연장을 독립변수로 하는 회귀식을 산정하여 비교하였으나 본 연구에서는 사용된 자료수가 적고 수리구조물을 이용한 회귀수량 등으로 인하여 갈수량이 실측유량과는 다소 차이가 발생하였다. 미계측 유역의 유량추정시에는 자료의 축척기간과 연도별로 안정된 호우사상, 유역의 적절한 배분에 따라 결과치가 좌우되며 본 연구에서 사용된 유량추정은 관측 자료를 기초로 한 간접적인 방법들이였다. 결과적으로 금호강 유역의 동촌 지점을 이용하여 유량추정방법들을 적용해본 결과 비유량법과 강우-유출모형을 사용하는 것이 적정하였으나 관측 자료의 축적기간이 길고 상하류 간의 유량이 안정된 유역에서는 지역회귀방법의 적용으로도 안정된 유량을 산정할 것이라고 판단된다.

The Total Maximum Daily Load(TMDL) Act just implemented as a new tool of watershed based water quality management, in Korea. Thus, there are a number of pending questions to resolve for successful settlement of the TMDL. The allocation of pollution source is a exceedingly sensitive issue on local development planning. The simple area-based allocation (SAA) is conventional method to allocate the administrational pollution information to watershed based information. The SAA has a limitation that it can't consider the characteristics of spatial distribution of pollution source and it has caused more uncertainty of TMDL. This study was performed to reduce the uncertainty of watershed-based pollution information using the spatial distribution-based allocation(SDA). In the specific area where pollution source is concentrated such as urbanized region, it has been certified that SDA could reduce a tolerance of pollution information dramatically. As a result of study, SDA is expected a effective tool for TMDL and to solve the conflict between development and protection.
