The purpose of this study is to provide information how to locate a apparel store based on target age, merchandise's type and price. Three trade areas in Seoul are chosen: Myeong-dong which is the biggest trade area in Korea; Kangnam station one of representative Kangnam trade areas; and Myeongil-Dong a neighborhood trade area. This study is mainly performed by analysing the locations of the stores in the given areas. The result shows that the main apparel stores in Myeong-dong are casual wear stores for young people with the range of mid-high price. The stores in Kangnam station trade area also sell the casual wear for young people but they are mostly mid-low priced. In the trade area of Myeongil-dong, however, there are various kinds of mid-priced apparel stores for residents of all ages. Apparel stores for formal wear, casual wear, and formal-casual wear tend to be located side by side. But other kinds do not. These results show that affinity is found in some types of apparel stores by the analysis of the next-door apparel stores.

The objective area of this study is a private house of common people at SimPori in the riverside area of OsipCheon. This area is the upriver of OsipCheon, and it was distributed at the 田-shaped House and the Dureong House with the composition of GuDl. Owing to the frequent interchange of AnDong and BongWha in the Young Seo district, the Kyup House and the SaBang House mixed with the 田-shaped House with GuDl of the YoungDong district. So the form of Folk House at this area is Dureong House. The Folk House of the seaside of SamCheok City is a compromised type among the 田-shaped House of GuDl in the north district and with MaRu in the south district, and introduced an indeterminate MaRu formed in the GaGokCheon area.

Objective : On the magnetic resonance image (MRI) of the infiltrating brain tumor, enhancement is usually higher in malignant tumor than in benign tumor, and tumor cells can invade into the peritumoral area without definite enhancement. In various pathological conditions, the blood brain barrier (BBB) becomes changed to pathological condition, allowing various materials extravasating into the interstitial space, and degree of enhancement is depend on the pathology. Authors performed dynamic MRI on enhancing and surrounding edematous area in order to evaluate the degrees of opening of BBB, to differentiate tumor from non-tumorous condition, and to determine its relationship with the recurrence of the tumor. Methods : Dynamic MRI was performed in 25 patients. Dynamic scans were done every 15 seconds after administration of Gd-DTPA on the enhancing and surrounding area for maximum 300 seconds, and the patterns of enhancement were ana lysed. The enhancement curve with initial steep increase followed by slow decrease was defined as "N pattern", those with initial steep increase followed by additional slow increase as "T pattern", and those with initial steep increase followed by plateau as "E pattern". Histopathological findings were compared with the dynamic scan. Results : The graphs taken from enhancing area showed "T pattern" regardless of pathology. In the surrounding area, "T pattern" was noticed in the malignant tumors, but "E pattern" or "N pattern" was noted in low-grade or benign tumors and non-tumorous condition. "T pattern" in the surrounding area was related to the malignant with tumor cell infiltration and recurrence. Conclusion : The results suggest that the malignant tumor infiltration changes the condition of BBB enough to extravasate the Gd-DTPA. Enhancement pattern in the surrounding edematous area may be a useful information to differentiate the malignant glioma with the low-grade and benign tumors or other non-tumorous conditions.

Porous media containing complex fluid passage have especially large surface area per unit volume. This study is aimed to identify the heat transfer characteristics of high-porosity metal foams in a horizontal channel. Experiment is performed under various heat flux, velocity and pore density. Nusselt number decreases with higher pore density. Metal foams shows higher heat transfer coefficients than pin-fin structure with the same porosity. This is due to the more complex flow passage and larger heat transfer area based on the structure of the metal foams. The analysis on the pin-fin structure may not be suitable to the metal foam structure but should be identified extensively through further study.

This study was performed to investigate the heavy metal contents and distribution in soil, sediment, and rice from the downstream area of ManKyeong and DongJin River. Of the sites on Mankyeong river area, site M-1(Mokchon bridge) showed the highest average contents of Cd, Cr and Pb in paddy soil. In DongJin river area, site D-3(Munpo) and D-4(Gerjeonri) showed relatively high level of average contents of Cr, Pb and Zn in paddy soil. The average contents of heavy metals in brown rice from ManKyeong river area were 0.10mg/kg for Cd, 0.99mg/kg for Cr, 2.07mg/kg for Pb, 4.44mg/kg for Cu and 32.03mg/kg for Zn while those in brown rice from DongJin river area were 0.14mg/kg for Cd, 0.74mg/kg for Cr, 1.78mg/kg for Pb, 4.57mg/kg for Cu and 33.60mg/kg for Zn. Zn showed the highest transportation-rate from paddy soil to brown rice while Pb showed the lowest. From the results of heavy metal analysis in sediments, the average contents of Cd, Cr, Pb and Cu were generally high in site M-5(Euonri) and D-4(Gerjeonri), the most downstream sites in Mankyeong river and DongJin river, respectively.

Needs for underground space development and utilization have been increasing in urban area. The conventional strutting method in excavation is effective to restrain the ground movements and displacements of earth structures but inefficient for workers because of small working space. The conventional earth reinforcement methods such as earth-anchor and soil-nailing also have limitation to apply in urban area due to threats to stability of adjacent buildings around excavation boundaries. Recently, many types of earth retaining structures are being developed to overcome disadvantages of conventional excavation methods in urban area. In this study, a series of numerical analyses were performed with MIDAS GTS, geotechnical analysis program and MIDAS Civil, structural analysis design program to evaluate behavior and stability of the new type of non-supporting earth retaining structure, called Temporary Tower System (TTS), consisting of tower truss structures with much economical and spatial advantage.

The purpose of this study was to analyze the spatial change of coastal area called Nampo-dong in Busan. And then the subject of research was chiefly concentrated upon the development of southern coast and the land-reclamation based on the commercial facilities after the opening port. There were various reclamation projects in the coastal area of Japanese settlement under the Rule of Japan. Busan Nambin Coast(Currently, Nampo-dong) was one of typical reclamation projects conducted in the southern seashore. Due to the characteristic of coastal area, fishery was developed well and the entertainment industry also grew rapidly with the characteristic of the short distance of urban centre. In this study, we investigated the process of reflecting the characteristic of spatial change that were pursued by communities at that time, particularly through the establishment and change of buildings.

While environmental pollution being developed, there have been some cases that residents on certain parts of Seoul area have cultivated vegetables in a small scale, and consumed the produce of theirs thinking them not polluted. Therefore the need for study about whether those vegetables and soil were polluted was growing. In this study, Seoul area (Tobong-dong, Chang-dong, Wolgyedong, P'il-dong, Oksu-dong, and Karibong-dong) and Kyanggi area (Changhang, P'och'an, Kap'yang, Yangp'y~ng) where pollution was thought to be less severe than that of the former were selected for the sampling area. Cabbage, pumpkin and young pumpkin were sampled and dried to be analyzed the contents of Cd, Cr, Cu, Ni, Pb, Zn, and moisture content was also analyzed. And at the same time 0.1 N-HCl soluble heavy metal content of soil was measured, and the results obtained were descrived as follows. Heavy metal contents of soil in Seoul and Kyonggi were Cd 0.184 ppm, 0.118 ppm, Cr 2.355 ppm, 0.441 ppm, Cu 29.16 ppm, 3.331 ppm, Ni 1.650 ppm, 0.829 ppm, Pb 26.77 ppm, 4.696 ppm, Zn 57.47 ppm, 14.94 ppm respectively. Heavy metal contents of cabbage in Seoul and Kyonggi were Cd 0.407 ppm, 0.241 ppm, Cr 0.388 ppm, 0.402 ppm, Cu 6.853 ppm, 4.486 ppm, Ni 1.479 ppm, 0.878 ppm, Pb 0.812 ppm, 0.258ppm, Zn 112.2 ppm, 54.86ppm respectively. Heavy metal contents of pumpkin in Seoul and Ky6nggi were Cd 0.011 ppm, 0.011 ppm, Cr 0,262 ppm, 0.197 ppm, Cu 3.302 ppm, 2.539 ppm, Ni 0.717 ppm, 0.369 ppm, Pb 0.257 ppm, 0.083 ppm, Zn 28.75 ppm, 14.01 ppm respectively. Correlation between heavy metal contents of soil and those of vegetables was represented high as a whole. In all heavy metals cabbage had higher values of concentrations than those of pumpkin (p<0.001). Concentrations of young pumpkin were higher than those of big pumpkin. It was probably due to the fact that young pumpkin containing not only inner part of pumpkin but also seeds was used as a sample. When classified by region, relatively high concentrations were observed in the samples of Karibong-dong, and in the sample of Jungtang riverside Cd was higher, and in the sample of Namsan Pb was higher than any other district.
