The uniformity of lighting distribution on the roadway is essential factor for drivers and pedestrians's safety during nighttime in urban streets. Also, the importance of roadside trees is one of the growing concern for better citizens' health and mitigating environmental impact on the urban street. But roadway lightings and roadside trees have different design or planting standards and they are not integrated in the systemic viewpoint for better safety of users during nighttime. The purpose of this study is to propose a simulation approach which assesses lighting quality in the view of illumination uniformity distribution of roadway lighting from design step and consider the layout of roadside trees. For improving lighting quality of roadway, simulation approach is needed for assessing the impact of diverse planting situation of trees and encouraged from beginning of design step for roadway construction.

In this study, we developed a modular rainwater infiltration system that can be applied for general purposes in urban areas to prepare for localized heavy rain caused by climatic change. This study also analyzed the system's effects on reducing runoff. An analysis of the system's effects on reducing runoff based on rainfall data and monitoring data obtained between September 2012 and December 2013 after the system was installed showed that approximately 20~22% of the runoff overflowed from the infiltration facility. Also, an analysis of the runoff that occurred during the monsoon season showed that 25% of the runoff overflowed through the storm sewer system of the urban area. These results show that the rainwater overflows after infiltrating the detention facility installed in the area during high-intensity rainfall of 100mm or higher or when precipitation is 100mm for 3~4 days without the prior rainfall. According to precipitation forecasts, torrential rainfall is becoming increasingly prevalent in Korea which is increasing the risk of floods. Therefore, the standards for storm sewer systems should be raised when planning and redeveloping urban areas, and not only should centralized facilities including sewer systems and rainwater pump facilities be increased, but a comprehensive plan should also be established for the water cycle of urban areas. This study indicates that decentralized rainwater management can be effective in an urban area and also indicates that the extended application of rainwater infiltration systems can offer eco-friendly urban development.

Just as culture is a collection of lifestyles, Cultural Properties is what is made over a long period of time and is left around us, whether it takes form or not. Many countries around the world have their own standards and are trying hard to preserve those with precious values. And in the case of Modern Architecture, because they are still in use In our daily lives and for the lack of recognition, they are continuously threatened during urban changes and developments. The purpose of the research is not to preserve Modern Architecture as done In the museum, but to seek a way for it to coexist with the changing environments of contemporary cities. Therefore, it is to recognize Modern Architecture as valuable assets, which expresses historicity in urban settings, and to seek the design characteristics of Modern Architecture. This is a process in order to find a new method for conservation of historicity. The result are as followings. Modern Architecture have their design characteristics and these can be applied as a design guideline. Therefore the form, material, and the colors of individual Modern Architecture can be analyzed so as to create a design guideline according to their styles. According to the analysis of Registered Cultural Properties in Seoul, they can be categorized into 6 uses and found the design characteristics of individual uses.

According to the change of the life environment and economic growth, the more highly a city has developed, the more concentrated is the urban function. That is, a city is required for adding more infrastructure. But, both limited land resources and financial problems made it impossible to add infrastructure. So, the necessity of multi-dimensional planning of urban infrastructure was recognized. Especially, in the urban residential area, a mixed-use of the playground of a school and the empty space of a park is desired to serve the issue of insufficient parking spaces. Schools and parks are closely connected to the center of a town, and playing a central role for the town life. For this reason, they are highly demanded in urban residential areas and also expected to be effective. However, we need to consider not only parking convenience but also the safety of users in design process, because people using parks and schools include young students and the elderly. In this study, we mainly examined physical characteristics and the utilization of schools and parks with parking facilities in urban residential areas. Then, we analyzed cases through comparing and evaluating in terms of convenience and safety. and weighed up advantages and disadvantages of each through the comparison of the schools and the parks having parking facilities. The results of this study are expected to provide fundamental references for preparing design standards for such facilities.

This paper presents a state-of-the-art review on the design, research and education aspects of fire safety engineering (FSE) with a particular concern on high-rise buildings. FSE finds its root after Great Fire of Rome in 64 AD, followed by Great London Fire in 1666. The development of modern FSE is continuously driven by industry revolution, insurance community and government regulations. Now FSE has become a unique engineering discipline and is moving towards performance-based design since 1990s. The performance-based fire safety design (PBFSD) involves identification of fire safety goals, design objectives, establishment of performance criteria, and selection of proper solutions for fire safety. The determination of fire scenarios and design fires have now become major contents for PBFSD. To experience a rapid and positive evolution in design and research consistent with other engineering disciplines, it is important for fire safety engineering as a profession to set up a special educational system to deliver the next-generation fire safety engineers. High-rise buildings have their unique fire safety issues such as rapid fire and smoke spread, extended evacuation time, longer fire duration, mixed occupancies, etc., bringing more difficulties in ensuring life safety and protection of property and environment. A list of recommendations is proposed to improve the fire safety of high-rise buildings. In addition, some source information for specific knowledge and information on FSE is provided in Appendix.

Urban transit is one of the most effective ways for efficient operation and construction of an urban transit by composition system which is liked originally such as rolling-stock, power, signal and infrastructure. Urban rail transit system is running in domestic, imports major equipments from advanced countries and setup for maintenance. But it takes long time because it does each organizations and lines. Also, signal, power and track system apply different standard by each construction organizations it causes an increasing construction of cost accordingly it desperately needs a systematic countermeasure. Therefore standard specification of urban transit have been establishing and operatingfor efficient operation of urban transit and base technology security that is populace ride to become a base of state economy. After track, power and signal system will be announced. Standard specification become more, the importance of administrationof standards is emphasized more. Specification administrator’s the importance which use a computing support tool recently in railroad part in embossed and is predicted to be more such forward. Therefore we propose the effective method of management with track, power signal system by constructed data-base system.

This study proposes an appropriate level of insulation standards by region through annual heating energy requirements according to regional climate. The reference buildings out of non-residential buildings approved by the energy saving design standard for buildings were derived in the previous study, in which the annual heating energy requirements for each building were as follows when the insulation standard for building members in four regions (Pyeongchang, Seoul, Gwang-ju, and Jeju) suggested by the energy saving design standard for buildings: $29.8kWh/m^2$ in Pyeongchang, $17.5kWh/m^2$ in Seoul, $14.4kWh/m^2$ in Gwangju, and $16.7kWh/m^2$ in Jeju. To satisfy the passive level of insulation standards for these buildings, in case that roof/floor of buildings in Pyeongchang and Seoul was $0.2W/m^2K$, the minimum window thermal transmittance should satisfy $0.9W/m^2K$ and the minimum wall thermal transmittance should satisfy $0.1W/m^2K$ in the case of Pyeongchang. On the other hand, the minimum window thermal transmittance should satisfy $1.5W/m^2K$ and the minimum wall thermal transmittance should satisfy $0.14W/m^2K$ in the case of Seoul. For Jeju regions, the minimum wall thermal transmittance should satisfy $0.34W/m^2K$ to meet the passive level of buildings. Based on the above results, the thermal transmittance of each member by region should take the outdoor climate condition of the region into consideration to satisfy the passive level of buildings.

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.
