This study aims at finding relationships between the competitiveness of cities and the size or distance of them, based on some premises; (1) the competitiveness can be measured on the interval-ratio level, that is, factor scores, (2) a hypothesis that the spatial interaction model is valid for the relationships can be generally accepted. Based on the general recognition a research hypothesis that the more is the population or the nearer is the distance from a central city the higher is the competitiveness score is constructed. According to the premises 5-factor scores and composite score are calculated by means of regression method, and the scores are regressed on cities' populations and distances from Seoul city. Using bootstrapping method for the tests of significance is effective due to small sample of 21 cities. Results of the analyses show that most aspects of the hypothesis should be rejected or adjusted. Scores on Health-welfare factor, public service factor, and commercial vitality factor have no relation to the cities' sizes or distances. But the results also find the facts that the strong (negative) relationships exist between (1) educational base factor score and population, (2) density factor score and distance. Although this study improves systematic and analytic understanding of spatial interaction patterns, the understanding should be invalid for the general context because it has used the data on 21 cities in the capital region at the time of 2009.

Openness to outside is one of the most critical advantages for high-rise buildings. However, the effect of openness can be decreased if it is blocked by other high-rise buildings, especially built within the building complex of commercial district. The purpose of this study is to identify the horizontal openness of high-rise residential buildings by comparing 3 different cases of building arrangement type. A new method of evaluation has been introduced on the basis of distance to measure the openness including the matter of securing privacy. As a result of this study, comparative analysis was possible and relatively plentiful results of analysis could be drawn out. Through the process of analysis, this study set the evaluation indicators suitable to the analysis of openness of unit households. Thereby, the results of this study are expected to be used as useful basic data in planning high-rise mixed-use buildings.

Interior design, evolved from interior decoration of the 20th century, is one of environmental designs which contribute to the overall well-being of human life-physically, psychologi-cally, and emotionally. Moreover, it is also a complex and multi-faceted profession that requires a strong understanding of not only human behaviors and the impact of the designed environment on them, but also of changing technologies and their potential effects. Furthermore, design is a participatory process which requires the application of research, and theoretical knowledge to resolve issues addressing the society. Indeed, there has been various kinds of researches in the interior design field that came about. Through scrutinization of master's theses and doctoral dissertations, this study intends us to grasp the current trend of interior design researches. Theses and dissertations related to interior design and architecture were and sources for this study. The subject of the analysis for this study was limited to the 560 titles of such like these, published from 1970 to 1996 by gradute schools related to interior design or architecture.

This study examines the 1960s' townscape through the small-scale restoration model in Seongan-dong and Jungang-dong, Cheongju, one of the historical cities in South Korea. In the 1960s, Jungang-dong actively was developed outside the north gate of Cheongju castle, and Cheongju's townscape was changed by the relocation of railway station and construction of city hall. In the streetscape, the new roads, the east-west Sajik-ro and north-south Sangdang-ro were opened instead of old railroads, and they clarified the typical grid road system with the existing Seongan-ro, which connected north and south gate of the old castle. In the buildingscape, city hall was built in front of the railway station outside the north gate of old castle, and had a great effect on the existing buildings and facilities. The public, educational, and commercial buildings had been replaced by reinforced concrete, and the cement brick & block public housing were distributed widely. But the existing dwelling areas, located in the inside of old castle and outside south gate, showed the low and dense townscape, sustaining the former streets and building types.

This study is conducted to evaluate the effects of root restriction on growth of maple(Acer palmatum Thumb.). Tow types of container such as clay pot(CP), root control bag(RCB) were used to restrict maple's root and each type of container was divided into 5 sizes. The containers with plants were buried just below the soil level and maples planted directly in the soil (nonrestricted root treatment) were included as comparison. Data were collected on dry weight of leaf, trunk, thick root, rootlet and soil water potential. We have analyzed, simple linear regression, Pearson's Correlation analysis, Duncan's multiple rang test, and Covariance Analysis using SAS statistical software. The results of analysis based on these data are as follows; 1. Total dry weight of maple in CP was significantly larger than in RCB. 2. Difference in growth reduction by the kinds of containers was induced by different hydraulic diffusion ratios between container and soil. Difference in growth reduction by the size of container was induced by the difference density of rootlet and soil moisture contents in the container. 4. Commercial products of root control of root control bag appeared not proper for countries in which fluctuation of rainfall is severe. Because maples in RCB were restricted by excess soil water in the rainy season, or by lack of soil water in the dray season.

In this paper, the wave run-up height and depression depth around air-water interface-piercing circular cylinder have been numerically studied. The Reynolds Averaged Navier-Stokes equations (RANS) and continuity equations are solved with Reynolds Stress model (RSM) and volume of fluid (VOF) method as turbulence model and free surface modeling, respectively. A commercial Computational Fluid Dynamics (CFD) software "Star-CCM+" has been used for the current simulations. Various Froude numbers ranged from 0.2 to 1.6 are used to investigate the change of air-water interface structures around the cylinder and experimental data and theoretical values by Bernoulli are compared. The present results showed a good agreement with other studies. Kelvin waves behind the cylinder were generated and its wave lengths are longer as Froude numbers increase and they have good agreement with theoretical values. And its angles are smaller with the increase of Froude numbers.

The purpose of this study is to examine and investigate the characteristics of locational facilities and the purchase and leisure patters of residents with its focus on downtown streets of Yeongam-eup which is a eup-level small town. In the subject downtown streets, commercial and residential functions coexisted. While most locational facilities were small-scale sale(buy), food(eat), and employment(public institutions) facilities which were needed for neighborhood life and supporting daily life, the lack of facilities which supported leisure life(enjoy) and represented small town identity was found. The most common frequency of using downtown streets by residents was 'almost everyday'; the most common intention to use was 'to purchase daily things'; and the most common purchase good was 'groceries', followed by farming machines, books, and stationery. It suggested that the use of downtown streets was characterized by daily neighborhood life. In particular, it was found that expensive goods(more than 500,000 won) were commonly purchased in neighboring middle or large cities. Thus, it is necessary to consider the option and professionality of goods. Finally, it is necessary to consider residents' accessibility through reorganizing a street form from car-focused to pedestrian-focused.

This Study aims at identifying factor and variables which have significant effects on user satisfaction with recreational resources and facilities in Juwang National Park and there-by establishes indicies of planning and / or management of the park. To test the causal models of this research, the data was gathered by self-administered questionnaires from users in Juwang National Park. The analysis of the data was conducted in two phases. The first analysis dealt with exploratory gactor analysis which identified major factors involved in satisfaction with recreational facilities in Juwang National Park. The second analysis tested the fit of causal models of this research to the data using LISREL methodology. The factor analysis identified six significant factors in satisfaction with recreational resources, The six factors are convenient park facilities, natural landacape resources, linear park facilities, mineral springs and Buddhist temples, commercial and sleeping accommodations, rest areas and open space for passive recreational activity. The second phase analysis tested the fit of the causal model for satisfaction with recreation facilities to the data. The phase identified statistically significant causal links among overall satisfaction with the park, and other indigenous factors and exogenous variables. From these causal relationships, implications for future management of Juwang National Park were suggested.

The purpose of this study was to assess functioni fo urban greenspace to reduce atmospheric CO\sub 2\ concentration. The study quantified carbon storage in urban greenspace and carbon emission by fossil fuel consumptio in Chuncheon. The amount of carbon storage in vegetation by land use type was 0.02kg/$m^2$ for commercial land, 4.36kg/$m^2$ for natural land, and 0.54kg/$m^2$ for the other urban lands. In 1994, total amount of carbon emission by fossil fuel consumption was about 257,358 metric tons, and the per capita carbon emission was 1.4 metric ton. Total amount of carbon storage in vegetation was 42,942 metric tons, approximately 17% of the carbon emission. This study excluded quantification of carbon storage in soils. The role of urban greenspace to sequester atomspheric carbon might be much greater, if a soil greenspace to sequester atmospheric carbon might be much greater, if a soil greenspace to sequester atmospheric carbon might be much greater, if a soil carbon storage is included quantification of carbon storage is included. However, increasing coverage of trees and managing them for healthy growth would not be sufficient for avoiding adverse impacts by future climate change. Additional measures should be followed such as an increase of energy use efficiency and development of substitute energy.
