A web based watershed and sewer management system was developed for the analysis of stormwater runoff and sewer flow, and for optimal operation of sewer works using ArcView and SWMM. SWMM and ArcView were dynamically linked together using Avenue and Visual Basic in order to construct user-friendly management system. The developed system was applied to Choonchun city to verify its utilities. All the relevant field data were analyzed on the basis of developed system, and the modeling of runoff and sewer flow was implemented using RUNOFF and TRANSPORT blocks in SWMM. This system was connected to the management system of surface and subsurface environment management system in order to develop an integrated environmental management system. Futhermore, this system will be a critical part of overall control system of sewer works including sewer line and wastewater treatment plant. As this system can provide comprehensive prediction of flow and pollution profiles and analytical tool equipped with Web-GIS, it could serve widely as a tool not only for optimal management, but also for decision support system to examine the efficiency of planning and implementation of sewer projects.

Buildings are responsible of major energy consumption globally. In addition, they are linked to thermal comfort. The need to provide comfort becomes more crucial in schools as they are the place where students learn, and develop their skills. This research aims to investigate the energy responsiveness of new and traditional school building design, where major variation in form, amount of external walls and glazing are different. The research focused on indoor microclimate condition of selected schools in the city of Jeddah where the climate is hot and humid using advanced tools for monitoring. The research uses advanced energy equipment to measure several aspects such as floor temperature, roof temperature, globe temperature and other factors which can lead to predictable thermal comfort of users. The findings suggest that a larger area of glazing shielded from sunlight has a greater influence on both indoor condition and general thermal sensation. The finding also suggests that the glazing ratio is a major contributor on indoor thermal pattern which can result in an increase in temperature profile between from $7-10^{\circ}C$. The findings of this research can assist in the improvement in the design of the prototype school building in hot and humid climate.

Under the guise of a residential environment improvement, distendedly designated Pre-Housing Renewal districts and Renewal Districts by Basic Plan for Renewal Projects are not promoted and leaved for a long-term so that residential problems have become worse. In case of the canceled Housing Renewal district, at the time when the district are canceled, the residential environment has become already superannuated for more than 10 years but there is no follow-up plan to manage that problem so that the exact management plan for those neglected districts is urgently needed. Therefore, the purpose of this study is to analyze the aspect of change of residential environment after the cancellation and indicate appearing problems by conducting on the case of Canceled districts of Daegu Housing Renewal District. This study will be the first step to seek practical management measures for canceled districts, and on the basis of this, the research will become a precedent to seek the sustainable planning measures for the designation and management of Renewal Projects from now on.
