In recent years, the change of urban function and the decrease in birth rate have given rise to merge, abolition and relocation of the existing schools. This study explores the possibilities for various land utilizations of disused school sites, using the trial case of 'M' elementary school at Bu-pyung Gu in Incheon Metropolitan City. 'M' elementary school has recently happened to need no more land to build another school because of decreasing the number of students. Firstly, it studies the land reuse theories in city, the development methodologies of disused sites and the legalistic and political authority and limits. It analyzes the urban spacial values and roles, such as the educational roles, spacial functions and development values of the land. In addition, this study make a questionnaire of local residents to converge the public opinions on the utilization of disused school site. Finally, it proposes the principal direction for the effective appropriation and an alternative for exploitation of school site targeting disused school site of 'M' elementary school.

Drought is a disaster that causes prolonged and wide scale damage. Recently, the severity and frequency of drought occurrences, and drought damage have been increased significantly due to climate change. As a result, a quantitative study of drought factors is needed to better understand and prevent future droughts. In the case of agricultural drought, several existing studies examine the economic damage caused by droughts and their causes, but these studies are not well suited to estimating crop-oriented agricultural drought damage and the factors that absolutely affect agricultural drought. This study determines which factors most affect agricultural drought. It examines meteorological factors and those related to agricultural water supplied by irrigation facilities. Rice paddy production per unit area is lower than the average from the last two years where agricultural drought occurred. We compare the relative frequency of agricultural drought impacts with irrigation facilities, effective reservoir storage, the number of water supply facilities, and the meteorological drought index such as Standardized Precipitation Index (SPI). To identify factors that affect agricultural drought, we correlate rice paddy production anomalies with irrigation water supply for the past two years. There was a high positive correlation between rice paddy production and irrigation water usage, and there was a low or moderate negative correlation between rice paddy production anomalies compared to the average of the past two years and SPI. As a result, agricultural water supply by irrigation facilities was judged to be more influential than meteorological factors in rice paddy production. This study is expected to help local governments establish policies related to agricultural drought response.

Some results of experimental investigation conducted to assess the effect of cement composite strength and ductility on the shear behavior and crack-damage mitigation of stud connections between existing reinforced concrete frame in school buildings and seismic strengthening elements from cyclically direct shear tests are described. The cement composite strengths include 50 for medium strength and 70 MPa for high strength. Two types of cement composites, strain-hardening cement composite (SHCC) and non-shrinkage mortar, are used for stud shear connection specimens. The special SHCCs are reinforced with hybrid 0.2% polyethylene (PE) and 1.3% polyvinyl alcohol (PVA) fibers at the volume fraction and exhibits tensile strain capacity ranging from 0.2 to 0.5%. Test result indicates that SHCC improves the seismic performance and crack-damage mitigation of stud shear connections compared with stud connections with non-shrinkage mortar. However, the performance enhancement in SHCC stud connections with transverse and longitudinal reinforcements is less notable for those without additional reinforcement.

The purpose of this study is to provide the school planning factors as emergency shelter after disaster. The school functions as the evacuation space areas could be classified into the evacuation center, education maintenance, and dwelling. Among these functions, the scopes of our study are limited to the functions of evacuation center and education maintenance. To carry out this purpose, we were comparative analyzed the shelter space problems of Korea and Japan's survey in the existing literatures. In results of our study, the evacuation center's functions are difficult to depending on the disaster types, such as the earthquake, tornado, and hurricane. On the other hand, the education maintenance functions are difficult to deepening on the victims occupied times in the school as emergency shelters. Based on these findings, the Korea school planning as the emergency shelters are desired to reflect that the evacuation's functions based on the disaster type of the damage from storms, and the education maintenance's functions based on the victim's occupied times in school for their safety.

In Korea, the relevant laws and regulations for fire safety in buildings have been revised. Since 2011, Performance-based Design has been conducted for large-scale or high-rise buildings. However, the Korea's performance-based design is still at a level where life safety evaluation using fire and evacuation simulation tools is compared with existing methods. Although related studies have been conducted continuously for the mandatory performance-based design, the fact that it is relatively unsatisfactory for design and construction of fire-fighting facilities as it mainly focuses on administrative and institutional improvement measures or computer simulation. This study collected 91 performance-based design documents that were carried out nationwide at the initial stage of implementation until 2016 to analyze the status of performance-based design of fire-fighting facilities. As a result, fire-fighting facilities, except for fire extinguish system facilities, were not properly designed for performance. Furthermore, the designers found that if corresponding facilities or higher-level equipment with upgraded performance is additionally installed, the performance-based design fared well compared to the existing the prescriptive-based design.

Building-integrated photovoltaic(BIPV) systems can operate as a multi-functional building components, which generates electricity and serves as part of building envelope. It can be regarded as a new architectural elements, adding to the building's aesthetics. Besides of these benefits, the application of PV systems into school buildings tends to play an important role in energy education to students. In this context, this study aims to analyse the applicability of PV systems into school buildings. For an existing school building, four types of BIPV designs were developed; rooftops, wall-attached, wall-mounted with angle, and sunshading device. Based on energy modeling of those BIPV systems, the whole 60.1kWp rated PV installation is expected to yield about 65.6MWh of electricity, that is about 50% more than the annual electricity consumption of the school, 44MWh. It was also found that the applicability of the PV systems into the school building was very high, and the rooftop systems with the optimized angle was the most efficient in energy production, followed by sunshading, wall-mounted with angle and wall-attached. It concludes that school buildings have a reasonable potential to apply PV systems in the aspects of building elements and electricity production.

As sewer flooding frequents due to localized and concentrated stormwater and increased non-permeable surface area after urbanization, building cities with sound water recycle and accordingly efficient management of rainwater is demanded. To do this, the existing sewage (including rainwater) fee imposition system should be philosophically evaluated. This study presents problematic issues of the existing domestic sewage fee imposition system considering the principle of sharing costs on the service of sewage and rainwater collection and treatment. Four methods to improve the existing sewage fee imposition system are suggested: 1) imposing stormwater fee according to Polluter Pays Principle, 2) clarification of the share of public sector, 3) reducing or exempting the sewerage fee for inhabitants reducing urban runoff by constructing their own rainwater management facilities, 4) imposing charge for discharging rainwater to sewers due to new development action. Short, mid, or long term planning for rainwater management is recommended considering the situation of each municipality.

Rural villages have many problems such as the collapse of rural village communities with continued over-depopulation and aging, reduced functions of towns and villages, deteriorated services with changes in the structure of settlement class and decreased use of the facilities. they also have difficulties in maintenance in spite of the increase of the roles of rural village community facilities. Various plans for the utilization of community facilities to promote the vitality of rural villages and the revitalization of communities have been needed. Thus, this study aimed to offer basic data to seek for future plans to utilize community facilities and reconstruct communities through an analysis of the current uses of energy and community facilities in rural villages. The results indicated that the consumption of petroleum was highest in mountain villages at an average of 187,475 won/month($137{\ell}$), followed by fishing villages at an average of 144,142 won/month($104{\ell}$) and rural villages at an average of 126,070 won/month($93{\ell}$). The rate of utilization of community facilities was reversely highest in rural villages at 84.3%, followed by fishing villages at 61.1% and mountain villages at 40.7%. This research also found that households saved energy when they used community facilities and areas with a high rate of utilization of community facilities at a lower average temperature in winter. It saved approximately 33% energy compared to other areas. Finally, efficient and economical methods for community facilities in villages to be newly developed and the remodeling of existing facilities should been needed in the future to contribute to reconstructing rural village communities that face a crisis of maintenance or abolition.
