  • Over-urbanization has contributed to the increase in traffic problems. This makes the need for effective road planning and design more important than ever. I have been able to learn how to build a new road, and how to use it. However, in spite of the importance of good road planning, there are no systematic standards or methods for calculating traffic volume on railroad routes. Therefore, in this study, to strengthen the competitiveness of railroads, the concept of line capacity is introduced to railroads, and a clear standard and method for calculating railroad line capacity are presented. Based on the results, the line capacity of main railway lines for domestic railways was calculated. By applying the method of calculating the line capacity presented in this study, the capacity of existing railway lines and newly expanded routes can be calculated. It is expected that our findings will be able to provide systematic standards that can be applied to yield a more effective investment and design planning stage; the findings will also help improve the efficiency of railroad operation.

  • The purpose of this study is to identify current condition of night lighting plan for the outdoor space in an apartment complex and to examine how residents perceive that environment. For this purpose, considerations and standards for safe and agreeable night lighting environment were examined through literature study. And a field study to determine the current state of the night lighting environment was conducted, and finally a survey was executed to find out residents' satisfaction, requirements and consciousness on that lighting environment of apartment complex. Findings of this study can be summarized as follows. Firstly, most standards for night lighting environment focus on the urban environment as a whole, so they have very few clear standards exclusive for the outdoor space of the apartment complex. Secondly, most of outdoor spaces surveyed in this study have met the basic illumination standard, but some spaces had parts where lights were off or out of order forming dark zones, and in some parts lights were screened by trees causing shades, poor safety and a narrowed sight. Thirdly, residents had interest in the night lighting environment of the outdoor space, but they were not fully satisfied with that environment. Fourthly, residents were negative about such factors of the environment as safety, convenience, recognition and aesthetics. These factors should be reflected in planning and improving the night lighting. It is expected that this study provides basic information necessary to plan safer and more agreeable night lighting, and to satisfy the residents' need for liveable apartment complex.

  • The space qualification has to be conducted by a high level of screening to ensure the design margin of devices, materials, manufacturing processes, units, modules, and subsystem or system. The space qualification according to traditional test standards proposed by US military, NASA and ESA involve high cost and tight schedule due to their conservative requirements. It is necessary to develop a space qualification guideline that is cost-efficient and schedule-optimized for the development of domestic satellites. In this study, as a basic research to develop the space qualification guideline, the articles related to space qualification in test standards document released from military and space agency have been investigated. We are planning to utilize the results as a basic database for establishing the independent tailored space qualification guideline.

  • Purpose: This study aims to emphasize interrelation between healthcare policies, design standards and hospital architecture of the United States since 1950s; to examine spatial characteristics of inpatient care facilities through case studies; and to consider the social implication of these spatial changes. Methods: In this study, reviewing the overall healthcare system, design standards and inpatient care facilities of the United States since 1950s, a total of five inpatient care facilities, one for each period, were selected in order to analyze the spatial characteristics. The spatial maps of Space Syntax were employed for analyzing five case studies. Results: The distance between the nursing station, the support service, and inpatient room were getting closer. The spatial structure of inpatient care facilities is transformed from tree structures to annular tree structures. This result shows that the efficiency between patient, staff and support service is higher and the depth of the spaces is getting deeper, which indicates that efficiency for improving healthcare quality affect the spatial structure of inpatient care facilities. Implications: In the future, if Korea's health policy is changed to a demand-oriented health care policy, this conclusion predicts medical planning of hospital will be focused on the efficiency.

  • Caused by the Cheonanham attack and the Yeonpyeongdo bombardment occurred a few years ago, and the recent North Korea's nuclear test, the war crisis between South and North Korea has been increasing. Accordingly, an interest in obtaining a temporary residential space, for the case of the outbreak of war, where people can reside safely over a period of time has been escalating. However, in the disaster relief planning guidelines of the National Emergency Management Agency, the standards on the temporary residential spaces in preparation for storm and flood or earthquake are included, but the standards on the ones in responding to war are not yet equipped. In particular, the standards on the underground temporary residential spaces that can accommodate massive victims should be developed in preparation. In this study, through a requirements analysis based on the survey of war victims and a comparative analysis between disaster-related laws and regulations, the direction of relevant system improvement for the utilization of temporary residential spaces in responding to war is established.

  • Since 'Hanok Expanse Support' has been started in Seoul, its target was expanded from renovation to new construction and from 'Hanok District' to all area in Seoul. The newly built hanok with Hanok Expanse Support had to follow the standards about the form of the hanok and adapt to modern lifestyle. However, the newly built hanok were planned with 'kan' since it retained the traditional wooden structure. So their composition of kan were considered to be influenced by the standards of each district and modern lifestyle. Therefore the aim of this study is to understand the architectural characteristics of newly built hanok in Seoul since 2000 focusing on the kan composition. Because of the differences in site conditions and the district unit plan, newly built hanok in Hanok District have more limited changes than Other District. However, kan is composed variously in horizontal and vertical ways to make the most space according to site conditions and most of the newly built hanok have opened courtyard rather than closed courtyard layout. With kan composition in various directions and kan added under the eaves, kan is highlighted in form. On the other hand, the composition of kan as an interior spatial element has changed and weakened because the lifestyle has changed compared to the traditional hanok and the 20th century urban hanok. Also the regular kan composition of Mom-chae and Nalgae-chae has changed. And kan is divided regardless to the wooden structure. Also, with the added kan under the eaves the main kan is dismantled inside. This paper indicates that although there is an undeniable premise that the case is restricted to hanok received Hanok Expanse Support on the condition of following the standards of the form of hanok, it is a part of the transitional changes that hanok is experiencing.

  • Multi-unit house, multi-household house, row house and apartments with less than 500 households were included in the list of anti-crime for buildings following the revision of the "notice of crime prevention building standards" on July 31, 2019. Strengthening the performance of crime prevention buildings is inevitable to increase the cost of building construction, including installation of preventive facilities and use of facilities that have secured performance. Thus an economic analysis on the costs and expected benefits of implementing the standards is required for social consensus. Economic analysis is divided into cost analysis and benefit analysis. This study aims to perform an economic analysis on the installation of crime prevention facilities in the buildings subject to expanded crime prevention obligations. Cost analysis is calculated as the sum of the cost of installation and the price of the crime prevention facilities installed for each target residential building. Benefit analysis is calculated as the social cost of targeted crimes that are expected to decrease due to the installation of crime prevention facilities. Economic analysis shows that the total cost of installing crime prevention facilities in residential buildings is estimated at 107.31 billion won per year, while the total benefit from enhanced crime prevention performance is estimated at 9.38 billion won per year. Considering inflation, benefits are expected to outpace costs in the 28th year since the system was implemented.

  • The aggravation of coastal erosion due to climate change has recently emerged as a global issue, and the international community is aware of the risk and is applying national consultations and various policies. In the case of coastal countries located in the Mediterranean Sea and the Caribbean Sea, coastal buffer zones and coastal management plans are established at a national level, and the United States is establishing coastal area management plans at the city level. In Korea, coastal erosion management areas are designated and managed to prevent coastal erosion and coastal disasters, but the number of designated areas and policies for coastal land areas are lacking. Therefore, in this study, we study policy cases applied to coastal land to prevent and reduce coastal erosion and coastal disasters through policy status and overseas cases, and seek ways to improve coastal buffer zone policies. As a result of the study, implications were drawn that expansion of the coastal buffer zone for coastal land areas and standards for establishing buffer zones based on scientific analysis are necessary.

  • According to the change of life environment and economic growth, the more city has highly developed, the more concentrated urban function. That is, city is required for adding infra structure. But, both of limited land resources and financial problems made it impossible to add infra structure. So, the necessity of multi-dimensional planning of urban infra structure was recognized. Especially, In Urban residential area, in order to secure parking area, It is on the increase that mixed-use of the playground of school in the high density area and the empty space of park. School and park is closely connected with town community, playing a central role on town life. For this reason, they are highly demanded for providing space in the urban residential area and also expected to be effective. However, people using park and school are almost young students and the elderly, it needs to consider not only the parking convenience also the safety of users in design process. In this study, we analysed the physical characteristics and the utilization of mixed-use of school and park. and then evaluated the case in the point of convenience and safety. For this, first we selected the case among the sites constructed in seoul, and divided 2type of 'slope type' and 'flatland type'. The meaning of this study is to suggest elementary standards for design in the point of multi-dimensional land use planning.
