While the zoning system has been developed based on the rationale of separated and specialized land uses to prevent negative externalities in the modern industrial era, the emergence of office-based new industries in the post-industrial era rather encourages mixed land uses to create agglomeration economies. This study aims to find historical basis to justify the reform of zoning system to promote both specialized and mixed land uses. When the zoning system was first introduced in Japanese colonial period by Chosun Planning Ordinance enacted in 1934, Special District within Manufacturing Area, and later within Residential, Commercial, and Mixed Areas respectively was institutionalized for specialized land uses, though it was not actually designated. When City Planning Law was enacted in 1962, Special District was substituted by Exclusive Areas (Exclusive Residential Area, Exclusive Manufacturing Area). Meanwhile Undesignated Area was designated for mixed land uses by Chosun Planning Ordinance, and later it was converted mostly into Mixed Area and partially into Green Area. Finally Mixed Area was substituted by Semi-Areas (Semi-Residential Area, Semi-Manufacturing Area) by City Planning Law in 1962. These demonstrate that Korean zoning system needs to revive the tradition that clearly promoted both specialized and mixed land uses.

In recent years, there has been a proliferation of commercial uses in the area where Gentrification occurs. In order to cope with such a diffusion phenomenon, it is necessary to derive the diffusion area accurately. Gentrification has a feature that occurs locally in a short time. Therefore, this study used the space-time pattern analysis to derive the diffusion area of commercial uses in Bukchon, a typical gentrified area in Seoul. Among the space-time pattern analysis, space time permutation statistics used in this study can derive the convergence phenomenon of time and space in a particular case with only the location information. The results confirmed that there has been three proliferation area in Bukchon, one started in 2007, other in 2013 and the other in 2014. In the earliest area, independent shops were the most popular, and the majority of them were restaurants. However in latter areas, there has been more chain stores and clothing stores than earlier area. The findings of this study indicate that space time pattern analysis can be used as a tool to analyze the proliferation by gentrification because it can derive accurate location and timing of the diffusion.

The purpose of this study is to research on the distribution and correlation of population, industrial employees and highest land value of Seoul. The followings are result of the study. First, the population of Seoul City in 2012 decreased by 0.3%, compared with that in 1996. While the population of Gangbuk decreased, that of Gangnam increased. Second, the number of industrial employees showed larger gap than population, and it showed larger regional gap on producer service. Third, Jung-gu in Gangbuk had the highest land value among commercial areas of Seoul, but there was no significant gap between Gangbuk(Jung-gu and Jongro-gu) and Gangnam(Seocho-gu and Gangnam-gu). Fourth, in the average of the highest land value of residential area of Seoul City, Gangnam was more expensive, because of facilities and living conditions of Gangbuk and Gangnam is big difference. Fifth, the regional gap of the highest land value and the lowest land value of Seoul City is commercial areas larger than residential area. Finally, there was no correlation between the distribution of population and land value, between the increase of population and that of land value, but there was positive correlation between the distribution of industrial employees and the highest land value of commercial area and residential area of Seoul City.

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.

An image analysis program with the function of measuring various quantitative characteristics in the transverse surface of wood was developed using Delphi 2.0. Data on pore characteristics (conditions for image processing, proportion of pores in relationship to other elements, tangential diameter, area, tangential and radial diameter, x and y coordinates of pore center, and geometric coefficients) were saved in text file format. In addition, the pore area histogram in the tangential and radial directions was saved as a BMP (bitmap) type file. Analyses indicated that quantitative characteristics such as the relative radial distribution of pores in a growth ring, pore tangential area histogram, and proportion of pore in lumen area appear to be useful in separating four diffuse-porous woods and four ring-porous woods on the species level.

The Anyang stream is one of the Han river in Seoul Metropolitan area. It is 35.1km long, has a basin area of $282.26km^2$ and touches seven cities of Kyounggido and some of Seoul Metropolitan area. The situations of Anyang stream have resulted in severe stream water pollution problems. The purpose of this study were to measure the hydraulic characteristics and water quality, to make the countermeasures to achieve the stream water quality, to suggest the future conditions to improve water quality trough the Hydrodynamic and Water Quality Modal(WASP4). As the result of Anyang stream water quality forecsat, they are follows. Sewerage systems in the watershed of the Anyang stream have to be amended for wrong systemn and constructed in the upstream area of Anyang. The discharge of industrial wastewater has to be throughly controlled from the upstream area of the Anyang stream. Hydrodynamic and Water Quality Model(WASP4) for this study revealed the future water quality of the Anyang stream by computer simulation.

This study examines the 1980 Census and the 1987 Travel Survey data sets, in order to identify commuting trends in the Seoul Metropolitan Area. The commuting field of Seoul includes the cities and counties contiguous to Seoul, as well as Inchon, Suwon and Ansan City and Paju County. The study finds little support for the expansion of the commuting field toward distant counties of Kyonggi Province; instead an intensification of commuting within the field is more salient. The most prominent trend, within the city limit of Seoul, is that journey-to-work toward the city center has decreased whereas peripheral journeys increased considerably. The work trips have increased most in the southwestern sector of the city; a moderate increase in the northeastern and southwestern sectors; and decreases in the center and the northwestern sector of the city. Factorial analyses of the work trip data also reveal the emergence of sub-regions of journey-to-work in the peripheries of the city. Such a spatial pattern of commuting changes resemble that of population changes, and correspond in part to the layout of the subway system.

This paper introduces the experimental results of sloshing model tests carried out at Seoul National University. Two 1/50-scale tanks, i.e., 2D and 3D models with the same shape, were manufactured for the comparative study. Particular interest was taken in the differences in impact pressures between the 2D and 3D models. Regular motion tests were conducted for different filling depths. For each filling depth, 500 cycles of regular excitation were imposed at each frequency. To observe the characteristics and severity of sloshing from the acquired pressure data, statistical analyses were performed, not only for the peak pressure, but also for the area-concept indices, which represented the amount of impulse.
