  • As of December 2016, there are 608,828 elevators in operation in Korea and 179,790 elevators in more than 15 years. 30.4% of all elevator are aging. Improved maintenance of the elevator and proactive replacement of the parts of the elevator can extend the lifetime of the elevator and ensure safety. An unclean environment reduces the lifetime of elevator parts. If you do not clean the environment and prevent preventive parts replacement, eventually shortening the lifetime of the parts connected to the failed part or causing more damage will result in greater economic loss. Also, the risk of elevator safety accidents due to failures of elevator parts will be increased accordingly. The study of optimum replacement time of elevator parts will contribute to prevention of safety accident of elevator and prolongation of lifetime of elevator through preventive replacement of elevator parts.

  • Purpose: The purpose of this study is to develop and apply an environmental impact assessment program for apartment building elements, based on the building materials of the LCI DB, which can link the LCA results of building materials and buildings. Method: For this purpose, a framework for building elements was established, and several building material combinations were developed. In addition, the LCA method for quantifying environmental load emissions from the building materials of each site was applied to establish an environmental impact database of the building materials of the LCI DB. Result: An environmental impact assessment program, based on a Microsoft Excel worksheet, was developed for apartment building elements. This program can link the environmental impact assessment of building materials and building units. To validate the program evaluation results that were obtained in this study, a comparative analysis was carried out using the results of existing evaluation methods. The error rate was estimated to be 5% for environmental impact assessment using existing evaluation methods.

  • Hot springs development will be more activated with the five-day work week system than before. Nevertheless, investment and development achievement of hot springs has not resulted in a successful performance to foster townships, and this calls upon locals to build a guideline to develop hot springs. This study intends to analyze laws on hot springs, which influence mostly on the hot spring development, to gather up the information on the present state of the development, and to suggest considerations for further development plans. Features of the hot spring development are as follows: One is that metropolitan cities will discover hot spring resources more than small cities. Therefore the development will be twofold : one for resort tour and the other for one-day rest and recreation. In addition, Korean laws on hot springs are more site development-oriented to support tourism and recreation than to protect environment and discover unused resources. This makes hot spring development easier and efficient being supported by hot spring law, law on territory development and use, and tourism promotion law. On the other side, planned landscape trimming can be uniformized and unharmonized in terms of local identity and environment-friendliness. This is why careful considerations such as goods and bads of the local resources, local history and culture are needed in hot spring development. A long-term development project should include remodeling based on local identity and development trends. The third point indicates that Korean hot springs development has recorded relatively low performance due to difficult private capital attraction, and a high fence on land purchase and development approval. It is essential to release restrictions on the hot spring development-especially on those whose development performance has not been successful so that best practice can be supported by the government in remodeling and marketing. New plans on hot spring development should be also examined based on developer's capacity and local authorities' volition on the plan. Last point shows that most hot springs development plans have been designed only based on territory utilizing plan and facilities arrangement, not considering much on fund-raising, operational plan or feasibility analysis. Therefore the tourism promotion law should reinforce guidelines on tourist site approval system by supplementing criteria. At the same time, an education on tourism development planning is necessary to deepen developers' understanding, since most developers are experts more on city development, landscape architecture, designing, constructing and engineering than tourism development.

  • The purpose of this study was to provide practical data for proposing the housing environment support policy, fit for returners-to-village. For the purpose, this study focused the patterns of returners-to-village according to their experience of rural life, and their ways of settlement like planning and getting land and house. The questionnaires were answered by 91 persons who were living in Chungbuk area, and were analyzed chi-analysis on their socio-demographic characteristics according to experience of rural life, preparation of settlement and construction. The ANOVA were used to analyze their pattern of return according to experience, the period for getting house, and their satisfaction level of house size. The results were as follows. First, the returners showed differentiated tendency according to their experience of rural life, in their age, family life cycle, education level and income source after return. The experience of rural life explained the purpose of return and the living pattern after return. Direct experience group was mostly occupational farmer; indirect experience group mostly pursued good health & green life; non experience group mostly pursued green life. Second, the experience of rural life also explained differentiated tendency of returning preparation. In raising money, direct experience group mostly raised it privately but indirect or non experience group mostly used bank loan. Third, the returners mostly constructed new houses; non experience group almost constructed newly, but there were cases to utilize existing or vacant house in direct experience group, and indirect experience group favored existing house or remodeling of vacant house.

  • This study is targeted on children's parks in Seogu, Daejeon with the goal of maximizing the usage and versatility of existing parks in the area by the survey and analysis of the general status of children's parks, land use near the parks, population, users, and traits of usage. For the purposes of this thesis this study has selected 65 of the children's parks in the Seogu District to monitor. It also focused on a number of these parks located in areas which underwent a lot of changes and needed an increase in usage and versatility. Based on the selection criteria, the four target parks, Wojeong, Meongwhack, Dosan and Wicdunjimi children's park were selected. The Survey shows that 55.9% of park visitors visited a park to 'rest and take a walk' and used 'main facilities' meaning resting facilities like pergola and benches. In the nighttime, the number of park visitors is so few because of safety problems. 50% of users were satisfied with parks. It shows that there are many respondents who want to recompose these parks as places for light exercise, resting, meeting, and as community symbols. Generally, these target parks don't reach their full potential and they also do not play their proper roles because they are hampered by the constriction of the law. These stick to an outdated idea of what a park should be like without considering the actual and practical needs of city dwellers. When it comes to the remodeling and refurbishing of these parks we have to rethink the planning process so that these parks may be more versatile and practical in order to accommodate the radical changes of users and patterns of usage.

  • The objective of this study is to propose a color plan for rural villages that seeks harmony between natural and artificial environments in consideration of the fact that as new and renewable energy businesses increase drastically, problems of landscape color occur in rural areas. To this end, the current color conditions over the target regions are examined in context of energy businesses; a land simulation is developed; a survey on the preferences is conducted with the result analyzed; and finally, a color plan for villages where energy businesses and non-energy businesses are conducted. For the survey, 40 photos including simulation photos and original photos of villages were used: the photos before and after the simulation was applied were shown to village residents. The validity of the selected colors was then evaluated accordingly. The survey was conducted among 15 residents in villages where energy businesses were conducted and 15 in villages where non-energy businesses were conducted. As new and renewable energy methods such as solar energy panels are utilized over rural villages in the future, selecting artificial environmental colors that can better represent the region's identity and that are in harmony with natural environments will be an important factor in community center or housing remodeling projects, local community development projects, and so forth. It is expected that the present study can be utilized as the basis for village color plans that seek to consider actual local conditions based on objective data rather than selecting colors uniformly or based on subjective judgment.

  • Because of their nature as public facilities, demands that former military facilities be utilized for the public welfare are increasing, thereby leading to an increase in cases in which these military facilities are reestablished as parks. Cases in which former military bases were reestablished as public parks were analyzed; as a result, several implications were derived. First, the objectives of public park projects should be examined from the perspective of the concept of urban regeneration and regional revitalization. Moreover, it is necessary that profits are yielded and that regional identity and history are reproduced through reusing existing facilities as much as possible rather than entirely remodeling former military sites. As parks become larger in size, bases should be reorganized into complexes rather than single facilities or programs. It is also necessary that parks be established in stages considering the enormous expenses required for building public parks. Consequently, because the special characteristics of military facilities can lead to insufficient on-site investigation in the process of establishing parks, thereby incurring a vast amount of costs for design adjustment and contamination disposal, this should be considered in advance. A method of delegating the development rights to partial sites to private businesses and supplementing the costs of park establishment and maintenance with development benefits should be examined. In addition, given that there are various interests and stakes in former military bases, a method of operating a public-private cooperative decision-making organization during project execution should be considered. Finally, policies related to urban parks need to be improved in order to raise funds, expand profitable businesses, facilitate social services and sponsorship, and encourage the participation of trusts and non-profit organizations in park operation and management.

  • Recently, the international community signed a climate change agreement to prevent global warming. Yet currently, the fossil fuels have been widely used in to supply building energy for cooling and heating. The Green Building certification (G-SEED), an energy efficiency rating for new or existing buildings requires that buildings meet certain conditions. Insulation is used as a building material to reduce the energy supply to buildings and to improve the thermal insulation, and it accounts for more than 90% of the total heat resistance provided by the building surface components that meet the energy-saving design standards of new buildings. In this investigation, a performance evaluation study was conducted through an experimental study by directly extracting the foam polystyrene insulation on-site during the remodeling of a building that was in the range of 22~38 years old. Through tests, it was found that the thermal conductivity of the extrusion method insulation (XPS) was reduced by 48% and the compressive strength of XPS decreased by 36% compared to KS M 3808, which is the initial quality standard. For bead method insulation (EPS) with a thickness of 50mm, the thermal conductivity, the compressive strength, and flexural failure load were similar to the initial quality standard. Therefore, in the calculation of the primary energy requirement per unit area per year, the performance of bead method insulation can be estimated simply by considering the thickness of the insulation, while a correction factor that considers its performance deterioration should be applied when extrusion method insulation is used.
