Certain complex forces are existing at the other side of a canvas. These are visual arrangements and within the arrangement, even the simple combination of dots and lines create more than visual patterns. No matter what form that visual art has taken, it is performed in a certain space and it is constucted with various visual elements. For effective communication, visual elements must form a stable sturcture by extablishing organic relationship among each other. These requires an understanding of the human visual characteristics and psychonology, because human sight senses the same biological and psychological visual elements differently in its force and weight, according to the position within a given space. Although the structure which controls such force and weight exists within a peice of work, it is a internal plan of the work that actually controls the communication through a man\ulcorner psychological reactions towards the horizontal and virtical structures within it. Moreover it is a visual statement that effectively expresses a theme or a message. This thesis has studied visual structures through the analysis of art pieces regarding of these kind of a visual picture plane, characteristics of a picture plane formed by a structure of force existing on the other side of the picture and the theory of visual balance. In addition, the aim of this study is to help designers who deals with visual image works to understand the visual structures and psychological recognitions and to apply these picture plane compositions at their real work by recognizing the psychological power within the construction elements.

Air Sparging (IAS, AS) is a ground-water remediation technique, in which organic contaminants are volatilized into air as they rise from saturated to vadose soil zone. This study was conducted to investigate the variation characteristics of TPH, VOCs and $CO_2$ for air sparging of diesel contaminated saturated soil. Initial TPH concentration was 10,000 mg/kg for saturated soil phase and 1,001 mg/L for soil aquifer phase. After 36 days of air sparging, the equilibrium temperature of 2-Dimension experiment system was $24.9{\pm}1.5^{\circ}C$. The saturated soil TPH concentration (in the C10 port close to air diffuser) was reduced to 66.0% of the initial value. The mass amount of $CO_2$ was 3,800 mg and 3,200 mg in air space (C70 port) and in unsaturated soil zone (C50 port), respectively. The VOCs production kinetic parameter was 0.164/day in the air space (C70 port) and 0.182/day in the unsaturated soils (C50 port).

In this experiment, photochemical reaction has been applied to destroy TCE in water phase. The main target of this work is to investigate the technical feasibility of large scale of solar detoxification reactor for water treatment. The results have revealed that solar detoxification utilizing photon energy from the sun is the most attractive process to decompose organic toxins in water phase at room temperature. The detailed results from this work are as follows; (1) The highest conversion ratio of TCE was obtained by using $TiO_2$, annatase as a photocatalyst among $TiO_2$ anatase, $TiO_2$ rutile and $V_2O_5$ under the same experimental condition. The anatase crystal structure was confirmed with XRD analysis, and its surface area was 7.748 $m^2/g$ from the BET-$N_2$ measurement (2) 0.1 wt% of $TiO_2$ anatase has been adopted as optimal quantity for batch slurry reactor at this experimental conditions. (3) The effect of hydrogen peroxide on the conversion of TCE was investigated. Its optimal quantity was 0.06 vol. % under this experimental conditions. (4) The effect of oxygen on the conversion of TCE also was studied by controlling the head space in photoreactor. Results indicated that sufficient amount of oxygen should be supplied to accomplish the highest conversion rate of TCE in water phase.

This study was carried out to evaluate degradation status of forest trails by analysis of soil physical and chemical properties in Mt. Jiri area of Gyeongnam province. Soil texture was loam in the forest area and sandy loam in the forest trails. Soil bulk density was significantly higher (P<0.05) in the forest trails (1.15 g/$cm^3$) than in the forest area (1.00 g/$cm^3$). The rates of pore space were lower in the forest trails (56.6%) than in the forest area (62.4%). Soil moisture content was significantly different (P>0.05) between the forest trails (13.3%) and the forest area (11.3%) Soil strength was higher at 5 cm of soil depth than at 10 cm of soil depth. It indicates that soil compaction by visitors could be affected at 5 cm of soil depth. Soil strength over 30 cm of soil depth was not significantly different between the forest trails and the forest areas. The content of organic matter, total nitrogen, available phosphorus, and exchangeable cations were lower in the forest trails compared with the optimum content of forest soils because of soil erosion with increasing visitors. These results indicate that it needs a counterplan to protect forest trails from overcrowded visitors.

This study is about Christian Dior's and Martin Margiela's fashion works that create 'New look' which leads the periodic ideology, philosophies, circumstances and the trend at that time. For the systematized interpretation, this study investigates the iconology of E. Panofsky, E. H. Gombrich and N. Goodman. Based on their theories, iconological analysis paradigm is made into four phases: I. Recognition of iconological form, II. Analysis of External Elements, III. Analysis of symbolic meanings and artistic will and IV. Aesthetic enjoyment and communication with a viewer. Christian Dior treats woman as a organic and architectural structure. He falls in love with himself such as narcissus and woman who wears his works. Dior's ego is visualized by woman and his works which are the symbol of narcissism and beauty. Martin Margiela makes form of clothes and at the same time destroys. Margiela deconstructs aura of clothes and tries to make it unfamiliar. Also he changes traditional idea of beauty and creates 'ugliness' which is a notion of dialectic. Margiela transforms elements of clothes which brings variation of thinking and makes it possible to create new look. Christian Dior and Martin Margiela are the creators of new look which visualizes the notion of habitus that is the space of self-exists. Fashion dose not have to be what people wears but it could be an image itself. It means that fashion is a part of ontology and it is a 'New look' which is based on economy, the standard of periodical beauty and ideal aspects. The creation of clothes is a work of embodiment of human being where it constructed or deconstructed.

Transition from mass tourism to post tourism is closely related with developing various types of cultural tourism. This study attempts to construct a conceptual framework of the development of cultural tourism through identifying the existing development stages of cultural tourism sites from birth to full development. This study clarifies that there exists an organic system among tourism, cultural activities and the production of cultural artifacts. It also found that development of cultural tourism sites goes through the following three stages: positioning and building place image, hard branding, and constructing local system. This study analyzes several key elements for respective of stages, which proved helpful in understanding the development mechanism of cultural tourism sites. It also tries to analyze tourism from an integrated, geographical perspective. The analysis gives us an understanding to the relations between tourism and various aspects of regional society and economy, thus contributing to the development of a system that will lead to active interchanges among those factors. Most of the theoretical background of this study: place identity, place image, activity space, local system and network are based on the concepts and ideas of human geography.

This study focuses on the genealogical analysis of the urban public spaces by the local history of Seoul which is significantly different from western cities. The analysis targets the discourse of the urban street which defines urban space-structure among the urban public spaces. Based on the analysis, we define the progress levels of urban public design policy in Seoul. Firstly, in 1960's and 1970's, 'urban reconstruction' was intensively carried out for the country modernization, and 'vehicle preferred street expansion' resulted in damages to historical inheritance, in-humanized street, and cultural uniformity. 1980's and 1990's would be defined as 'politic acceptance of plural values to the urban street.' There were the Olympic Games held in Seoul in 1988, which were the celebrations of the 600th capital establishment and the autonomous local government system. In the meanwhile, diverse values on the urban street were discussed in terms of globalization. There also were the self-reflection for the urban skyscrapers and high-population rate, the cultural uniformity of urban street, and the commercialization in downtown with urban reconstruction plans. Then, the sense of landscape and amenity was focused. Various urban projects and regulations were held according to the changes of value recognition. 2000's can be defined as 'introduction to the organic integration and the urban public design governance.' In the 21st century, types of recognition have changed significantly, which include publicness, humanism, sustainability, symbolism, artistry, placeness, and communication. They cause the establishment of ordinances and the installation of integrated organization via urban design administration. The legislation has been revised in order to support the various methods for the maintenance and operation of urban landscape in terms of local characteristics. New regulations were established for residents to participate in the processes of the urban planning with street design policy.

The purpose of this study was to find the basic application of Disporum genus in landscape-arc-hitectual space. Environment of native site (Daeducksan, Piseulsan) and growth characteristics of experiment plot were investigated and analyzed in this study. The results of this study were as follows; 1. In the case of environment of native site, the relative light intensity was about 10% and distribution of species were primarily north slope. Gradient of Daeducksan and Piseulsan were 10$^{\circ}$, 18$^{\circ}$ Soil textures was Lic both and field capacity of Daeducksan and Piseulsan were 69%, 73.5%. The soil pH of Daeducksan and Piseulsan were 6.1 and 5.8. The both content of organic matter and C.E.C. were high markedly. The P2O5 content of Daeducksan showed high but total nitrogen showed nearly the same level when comparing with the common dry field condition. 2. In tree layer, Daeducksan composed of broadleaved forest of 80% involving Quercus variabilis, and Piseulsan composed of coniferous forest of 80% involving Pinus densiflora on the other hand. Daeducksan, therefore, was more appearance species than Piseulsan in herbaceous layer. 3. Result in ANOVA Test, significance followed with light intensity was recognized in plant height, leaf width, leaf length, leaf thick and No. of leaf, while in the case of soil was not. Plant height was longest in 1% and leaf width, leaf length was largest in 25%. Therefore ornamental value of leaf was the very best in 25%. 4. Result in correlation coefficient analysis, plant height was correlated leaf width, leaf length. The longer plant height, the smaller leaf width, leaf length. In relative light intensity of 1%, flower was hardly expected because of the more shade, the less flower. Disporum smilacinum is expected great use as ground covers in the shades of tall-building or hdavy woods.

This paper begins with the thesis that the so-called 'Be Slow' Movement has not only affected the contemporary life style but also the current fashion trend in the West as well as in Korea. The influence of the 'Be Slow' Movement on the everyday life of Western and Korean society can be documented by recent books, news reports, and many articles from various kinds of mass media and fashion magazines since the year 2000. The results of this study can be summarized as follows. First. the 'Be Slow' Movement is a new cultural phenomenon and very different from that of the past century. It has emerged very recently and it could affect the life style o( its followers for a long period of time. Second, the influence of 'Be Slow' Movement on everyday life can be witnessed in many behavioral choices. such as the preference of organic food and natural cooking for food and the preference of rural life and a green patch of land for housing. Some aspects of the way of rearing the children and long-term planning of one's life are also under the influence of 'Be Slow' Movement. In a way. the life style Proposed by the 'Be Slow' Movement is somewhat similar to that of 'Bobos'. Third, the influence of 'Be Slow' Movement on the current fashion trend can be observed in the appreciation of time-consuming labour and increased usage of D.I.Y. clothing. The higher value of fashion goods with handcrafted part or scarce luxury item are good examples of the influence by the 'Be Slow' Movement. One can say that the 'Be Slow' Movement is not retrogression, but a re-creation of time and space to be grateful for one's life. Thus, it is not anti-technology but a commercialism with technology in order to enhance the quality of life and to place people in the center of production and consumption. Consequently, one may say that the 'Be Slow' Movement is a appropriate and affluent way of living.

Biogas production and utilization are an emerging alternative energy technology. Biogas is produced from the biological breakdown of organic matter through anaerobic digestion. Biogas can be utilized for various energy sectors such as space heating, electricity generation and vehicle fuel. Especially, to be utilized as vehicle fuel, raw biogas needs to be upgraded that is mainly the removal of carbon dioxide to increase the methane content up to more than 95 ~ 97 vol% in some cases, similar to the composition of fossil-based natural gas. Usage of Biogas as a fuel of vehicles have an effect of reducing $CO_2$ emission compared to fossil fuels. Biomethane which is produced by upgrading of biogas is regarded as a good alternative energy and usage of clean energy is encouraged to deal with air pollution and waste management as well as production of clean energy. Recently, biogas projects for vehicle fuel are newly being launched and Korea government have also announced a plan for investment to develop biogas as a transport fuel. In this study, it is aimed to examine the potential feasibility of biomethane as a transport fuel. As a results, the status of biomethane, quality standard, quality characteristics, and upgrading technology of biogas were investigated to evaluate of biogas as a vehicle fuel of transportation.
