The multifamily housing has various advantages in construction cost, land-use intensity. KRIHS(1997) recommended the proper scale of th multifamily housing as 800 households in constructability, 1,000 households in facility compactability, 500 households in social aspect. At the early planning stage of project, the size of the multiftmily housing has, until now, been maximizingly considered under the regulation on which has been emphasized at the building volume ratio, land area, etc., except for the expenditure during the maintenance stage. This paper aimed at providing the proper size of multifamily housing in aspect of area and household number with maintenance cost at the early stage of project. For these, it took 곧 average cost function which is made from the 3-rd quardratic form and analyzes the unit increasing rate of the average cost. It surveyed in nationwide focused on the central heating system using diesel and kerosene. The number of samples is 88 and items of management cost is 11. The results are as follows ; first, 3rd-order quadratic function is proper at explaining the cost variation, considering the multicollinearity and statistics. Second, the proper size of multifamily housing is recommended with 83,000 $m^2$ on management area, 820 or over the 2,630 household number in aspect of total management cost.

A road is a fundammental public traffic facility for transporting people and goods. Road designer should determine the best route considering various conditions to minimize environmental bad effect due to road construction and show road functions sufficiently. In this research, we tried to select the optimal route location by comparing candidate routes considering weights of various items such as land use, slope, aspect, land price and so forth. The candidate routes were analyzed and visualized from built data using a GIS software and then compared with the existing route.

The objective of the study is to analyze the impact of zone adjustment by comparing the changes from 2011 to 2018 of social and environmental factors such as the special-purpose area, actual construction activities including building development, land use environment, and officially assessed individual land price in the areas released from the National Park Zone during the second National Park Zone adjustment during 2010 to 2011 with the social and environmental factors in the areas that remained in the National Park Zone during the same period. We intended to investigate the problems of the second National Park Zone adjustment and explore alternative implications for the third National Park Zone adjustment. As for the special-purpose area, 80.4% of the released areas were converted to planned, production, and conservation area while 15.6% changed to the agricultural area, and 4.0% remained as the natural environmental conservation area. Regarding the change in building development scale, the average size of construction in the released area since 2011 was $106m^2$ while that in the retained areas was $91m^2$. For the land use environment, the rate of change from the natural area to developed area was 1.9% in the released area and 0.7% in the retained area. The officially assessed individual land price increased by 11,911 won in the released area and 4,413 won in the retained area. Although both areas showed an increase in the land price, the difference of officially assessed individual land prices was about 2.5 times. The problem concerning the private property rights of local residents in the national parks is still a challenge, but the second National Park Zone adjustment has resolved the problem significantly. Accordingly, it is necessary to offer the benefits for the residents in the national park area by analyzing the park zoning and park facility planning to present the rational alternative. It is also necessary to establish a support system that encourages the collaborative cooperation between the park authority and residents and assures that the residents to have pride in the national park.

Urban areas generate large amounts of stormwater and non-point source (NPS) pollutants during rainfall events. These are caused by various land use runoffs, vehicular and human activities and increased impervious cover. The increased runoff and NPS pollutants cause water quality deterioration in the receiving waters and adversely affect the aqua-ecosystem. These environmental impacts could be reduced through the application of low impact development (LID) techniques. In Korea, more than 80% of the total rainfall occurs in summer and most of these were 10 mm or less. Therefore, if the LIDs developed were able to cope with rainfall of 10 mm and below, NPS management could be efficiently conducted. This research was performed to determine the effect of varying amounts of rainfall on the performance capability of an established infiltration and filtration facility (IF facility) that can be applied to Korea's common rainfall ranges. The IF facility area was 1.75% of the catchment area, however the facility treated more than 40% and 60% runoff volume and pollutant reduction respectively for a 10 mm rainfall. Lastly, higher volume and pollutant reduction could be attained when the LID area was at least 2% of the entire catchment.

This study is about architectural design for rural housing block redevelopment for districts with existing residents considering sustainable development. The study suggests development direction focusing on preserving the regional characteristics, and presentation of suburban-style housing complex reflecting on the future tenant's individuality and demand. The preexisting development approach for suburban-style housing complex which was planned by the developer, failed to recognize taste of the future tenants. Profitability being the priority, it also resulted in a serious environmental disruption. In this development however, through a systematic direction for site development and site analysis, conducting surveys through future tenants, attempted for a continuous growth of the community. The study is presented covering the following areas; site's pathway system, nature conservation plan, lot plan, land use, arrangement plan, housing plan and community facility.

The purpose of this paper is to understand the key factors for efficient maintenance of rapidly aging facilities. Therefore, the safety inspection/diagnosis reports accumulated in the unstructured data were collected and preprocessed. Then, the analysis was performed using a text mining analysis method. The derived vulnerabilities of tunnel facilities can be used as elements of inspections that take into account the characteristics of individual facilities during regular inspections and daily inspections in the short term. In addition, if detailed specification information and other inspection results(safety, durability, and ease of use) are used for analysis, it provides a stepping stone for supporting preemptive maintenance decision-making in the long term.

Due to recent urban maintenance project for the aged towns, the reconstruction of apartments into super-high-rise and high-rise apartment structures has been approved for concentrated use of land, and accordingly the infringement on sunshine for nearby residential area is rising as a social issue. Especially the educational environment conditions according to infringement on sunshine in educational facilities are posing many problems. Accordingly in this study, for such sunshine analysis of educational environment, Auto $CAD^{(R)}$ software has been used to construct the 3D model for the educational facility structures. And with the simulation technique, the windows and the schoolyard of the education facility were set to be the lighting standard surface to take measurements for the sunshine environment of the educational facilities by the minute from 8:00AM until 4:00PM for the sunshine amount by true solar time according to the movement of the sun. Also, the sunshine environment of the education facility according to the damage before/after new construction of apartments was charted, and through comparison with the video produced by sun shadow projection method, the sunshine amount of the educational environment could be verified. In future, it is expected to be efficiently used in the sunshine analysis of education environment utilizing such simulation techniques.
