Korean power system has some problems like as curtailing investment and the NIMBY (Not In My Back Yard) phenomena, because of power demand concentration in downtown area. In this time, superconducting power devices rise as a very attractive solution. This study proposes a basic concept of superconductivity power system with bulk capacity, and identifies the items for technical and economic analysis. The proposed system consists of superconducting cables/transformers/FCLs(fault current limiter). The basic concept is to replace 154kV conventional cables with 22.9kV superconducting cables and to convert a 154kV substation into a 22.9kV switching station in downtown area.

On the other hand, the Municipal Building of Busan was a symbolic structure that shows the history of Busan. The Municipal Building of Busan has inherited the construction location and site, including the speciality of Choryangwaegwan, and is a good example of the process of inheriting the authority of the former space through the appropriation of the building. The Municipal Building of Busan was relocated to the edge of the coast in 1934 because a small and dilapidated building failed to function properly. The relocation of the Municipal Building of Busan in 1934 was the origin of changing the coastal space in downtown. As a result, landfill sites along the coast were in the limelight and developed into the downtown area of Busan after Korea's liberation.

The HIBRAND located in Yangjaedong, Seochogu, Seoul is a large complex shopping center of total space 48,000 p'yongs which consists of a nineteen-story business facility and a six-story sale facility. In the case of a big construction work in the downtown, they are suffered much difficulty by construction period and working space lack. They, however, can satisfy construction period, constructability and quality using a PC system in HIBRAND. Also, we maximized the advantage of each material being the abreast of a RC and steel structure method partially and devised a reasonable copula. A PC system with advantages of construction period, constructability and quality assurance should be actively practiced to big downtown construction work.

The size of the construction projects become huge and complex, and the depth of excavation for the underground structures become deeper. Also the working area is not enough for loading materials and temporary facilities. This is the most case of recent construction projects in downtown area. Top-down is the most useful method for this kind of construction projects. Top-down construction method consists of supporting method, retaining wall type, foundation type and construction direction such as up-down or up-up. construction managers have to select sub-elements for top-down construction method in planning phase. This study is to suggest the sub-elements selection model for the top-down construction method, and the case study is conducted for evaluating this model.

Cool island intensity urban green space was investigated based in Dalsung Park, that is one of the largest parks in Daegu. Cool island intensity(CII), which is defined as the temperature difference between the green space and its surrounding built-up areas, shows time variations. A through-year measurement(2008-2009) of ground level air temperature revealed seasonal variation and relationship to the atmospheric condition of CII. The temperature variation in the park and the reference downtown Daegu was as same order as CII. The noontime CII is larger in summer than that in winter due to the leaf fall of the park trees. On the other hand, seasonal variation of nighttime CII is not so clear. The nighttime CII was larger under the stable atmosphere.
