In recent year, construction of national infrastructure, variations of agricultural environment, urbanization of rural life-style, and other things have influenced on rural area. Therefore, its landscapes have been changed rapidly. As a result of it, rural landscape should be controlled with amenity and totality. That is a rural amenity control planning. The purposes of this study is to consider characters of rural settlement area, the directions of landscape control planning as an environmental planning, the structure of rural landscape, the process of rural landscape control planning, and its frameworks. Main viewpoints of landscape control planning in rural settlement are as follows; the using of regional resources, the harmony of surrounding environments, the harmony of natural ecology, locating of facilities, the development of new landscape material, maintenance of sequencing, symbolizing, unificating, and opening, the using of natural/regional materials, the using of waterfront, the making of stories.

As the elderly population increases, concerns for the elderly's welfare become greater both quantitatively and qualitatively. In order to give a chance for the elderly to live in familiar dwelling and regional context to which they are accustomed, and to participate in their society actively, it is of great importance that suitable living spaces must be provided for the elderly. The practical ways of providing people with good living environment and its easy maintenance for healthy and valuable lives were discussed in this paper. This research is designed to propose pertinent policies related to social issues concerning the elderly. 137 seniors over 60 living in Gwanaju city were sampled and surveyed. The scope of planning for the elderly's lifestyle and welfare is divided into two parts, one is planning of space for the realization of stable and spacious dwellings and another is urban environment planning capable of supporting healthy and affluent lifestyles. Also, the realization of stable housing, the construction of urban structure for a healthy life, and the provision of barrier-free living conditions are investigated. For increasing the degree of stabilization and improvement for the elderly's life, self-governing bodies should grasp the demands of living condition and spatial requirements by taking the lifestyles of the elderly into account in urban or regional levels. Then, a master plan including development, improvement, execution, and maintenance of proper housing facilities and urban environments should be made for the best results.

This study investigated how external environmentally-friendly factors adopted to improve the quality of outdoor spaces have been designed and used in the construction of apartment complexes. The goal of this study is to determine what areas should be improved through environmentally-friendly ways to create natural outdoor spaces in apartment complexes and enhance their availability and usefulness. For this study, 21 environmentally-friendly factors were chosen and a checklist by specific item was prepared. This study examine how these items were applied to basic planning, detail design, and construction in 4 target areas. As a result, it was found that the development of environmentally-friendly residential areas was an ultimate goal of the project during basic planning and design. All target areas focused on developing an inner greens network, eco-pond, brook, and pedestrian track as well as the growth of a variety of plants. Some differences have been observed, however, in terms of method. Furthermore, due to economic and technological problems and poor construction site conditions, green walls/green roofs/pedestrian tracks/use of rainwater have not been properly promoted. These kinds of problems must be improved through the development of environmentally-friendly construction methods and materials, the expansion of natural grounds areas, economic support, a satisfactory repair and maintenance system.

본 연구는 임도사업의 계획과 유지관리 단계에서 임도 관리자 집단의 의식성향을 파악하여 체계적인 임도 정책 수립을 위한 기초자료를 제공하기 위하여 수행하였다. 임도의 계획과 유지관리에 대한 설문조사 결과, 임도 노선의 계획시 고려사항으로는 육림작업, 산지재해 예방, 목재수확 등의 항목에서 높은 중요도를 보였으며, 간선임도에 대한 선호도가 가장 높게 나타났다. 또한 임도 유지관리 작업의 적절성에 대해서는 두 집단 모두 인력 및 예산부족으로 인한 어려움(92.9%)이 있다고 응답하였다. 임도의 개설로 우려되는 주요 피해형태로는 사면붕괴로 인한 인명피해, 사유지 통행에 대한 분쟁 등의 순으로 나타났으며, 현재 실행하고 있는 임도 유지 관리작업의 주요 내용으로는 배수시설의 정비와 노면정비가 높게 나타났다. 임도시설에 대한 주요 보완사항으로는 배수시설, 비탈면 녹화와 안정에 대한 응답이 높게 나타났다.

고장의 특성을 예상하는 것은 미래의 고장을 예견하고 최적의 교체간격을 결정할 수 있도록 해주기 때문에 정비 계획에서 매우 중요하다. 본 연구에서는 신뢰도 해석에서 가장 전통적인 방법 중의 하나인 확률지에 도시하는 기법을 이용하여 J79 엔진 Transfer Gearbox의 고장 분포를 검토하였다. 고장 데이터에 대한 적절한 분포를 찾기 위해서 다양한 확률분포가 이용되었으며, 얻어진 상관계수는 고장데이터가 대수정규분포에 가장 근접함을 나타내었다. 예상되는 비계획 정비행위의 횟수와 다양한 비용 비율에 대해서 최적의 교체간격을 구하였다.

Safety is soaring up as a core value in accordance with the recent improvement of operating speed & incidents. rolling stock is a kind of system which works together with several components. one component has an effect on the sub-system, which can cause to the train safety operation, therefore reliability management of the major components of rolling stock is a kind of solution to the safety operation of train, but realistically maintenance in korea performed based on period rather than TBO of major components, but Japan does new maintenance system based on the major components, which optimizes maintenance tasks. actually Japan can apply to new maintenance system because they are ready in planning step but in this study, making a reliability data of major components and review the adaptability of new maintenance system to the rolling stock operating in Ansan line.

This study finds out and suggests success factors for the application of RIMS project through the case study of Seoul Metro and literature survey. The successful application of RIMS needs expert knowledge and concept of BOM, standardization of maintenance planning, check lists of heavy maintenance inspection, organization structure of rolling stock maintenance offices, material management system of warehousing and the process of parts repairing between offices, connection of material ordering system, problem solving of circular spare parts administration among inspection, maintenance, and material organizational units, systemic serial number management of parts with RFID, daily closing diary connected with work process chart, and sufficient period of RIMS's test run. RIMS contributes to real time management of rolling stock maintenance, transparency of management, reliability of train operation, customer satisfaction, and management innovation.

The maintenance management in buildings has got more important by the increasing complexity of building sizes and use. Nowadays an expectation and a possibility of BIM technology become accepted as a new construction management method, therefore many studies and legal systems of it are being suggested actively. Although orders for BIM projects are supposed to be increasing, at present the BIM information accumulated from planning and design still doesn't have its continuity at the maintenance step after completion of construction in terms of LCC. It can't use the possibility that BIM originally has, and also causes some confusion in communication. This study analyzes and classifies required information in terms of BIM in the range of estimating repair costs of apartment buildings, as an example of a way to use BIM information at the maintenance step.
