In order to research into the devel of the concept of movement and speed in our own way and compare with the Piaget's method, and then find out the formative period of such development, we have put the 192 primary school children as the model and obtained the following results. 1. As their grade upyards, all the experimental subjects showed the gradual progress generally regardless of sex or regions, while only the relative speed showed irregular progress. 2. There was no experimental subject which showed any remarkable sexual characteristics. But in the relative movement, the lower grade boys and higher grade girls made progress. In the subjects of circulation movement, intuition of speed, relative speed and speed of simultaneous movement, the boys marked better progress, whilst the girls were advanced a little in the speed of continuous movement with, different distance and time. 3. There was no conspicuous difference between the urban and rural areas, except a slight tendency that the urban children made better progress in the change of progressing direction, native continuous procedure of periodical movement, travelling road, and the speed of continuous movement with different distance and time whereas the rural children were more advanced in the relative movement, relative speed and intuition of speed. But it should be 'taken into consideration that the rural regions in our case were relatively developed in comparison with the traditional rural communities, which may explain about little regional difference. 4. Comparing our research results with the Piaget's theory, we have reached below results. Our research reports that the formative period of the conception of the problems of diverse progressing direction and a native continuous procedure of periodical movement was simultaneous, at the Piagetian level(at the fourth grade) which coincides with Piagetian theory. The travelling road should be made up a little lower at 2A/2B according' to Piagetian Level, whereas it was formed at the 4th grade as shown in our previous research. Intuition of speed should belong to the prior stage to concrete operation, but our research shows it was formed late at the 4th grade. Composition of displacement was made at the 6th grade, and it was almost equal to the first stage of formal operation(3A). But in the subjects of relative movement relative speed, the speed of continuous movement with different distance and time, relation and preservation of invariable speed, and accelerated motion, even 6th grade children marked a poor record. Summed up, the procedure conception as a basic movement conception coincides with the Piagetion level. But as for speed intuition, relative speed and speed fixation, it was Jar behind Piagetian level. Therefore it is required that we have to concentrate on the systematic training in these parts on the spot.

Potentials of AR CDM project in North Korea are assessed and feasible land area for AR CDM project is estimated. According to our estimation, There could be 515,000 hectares of forest lands deforested before 1990 in North Korea and 8,854 hectares at the regional level of Gae-sung City, which are eligible for AR CDM project, based on researches of satellite image analyses conducted from 1980's to 1990's. A baseline scenario assumed 44.73 tones of carbon stored in soil per hectare with no vegetation above ground remained during the project period following the default value of IPCC's Good Practice Guidance for LULUCF considering soil structure, climate and land use of the project area. The scenario also assumes that black rocust (Robinia pseudoacacia) is planted and the CDM project is implemented for 20 years. The costs for producing greenhouse gases CER (certified emission reduction) credits include costs of tree planting and forest management, and costs of project negotiation and transactions for issuing the credits. It is estimated that 376 tones of carbon dioxide per hectare can be accumulated and 503 temporary CER credits per hectare and 265 long-term CER credits per hectare could be produced during the project period. It is estimated to cost US$ 4.04 and US$ 7.67 to provide one unit of temporary credit and long-term credit, respectively. These values can be regarded as the cost of conferring emission commitment of a country or a private entity. However, it is not clear which option is better economically because the replacement periods are different in these two cases.

After the permanent shut down of Kori Unit 1, various decommissioning activities will be implemented, including decontamination, segmentation, waste management, and site restoration. During the decommissioning period, waste management is among the most important activities to ensure that the process proceeds smoothly and within the expected timeframe. Furthermore, the radioactive waste generated during the operation should be sent to a disposal facility to complete the decommissioning project. Square and cylindrical concrete re-package drums were generated during the 1980s and 1990s. The square, containing boron concentrates, and cylindrical, containing spent resin, concrete re-package drums have been stored in a radioactive waste storage building. Homogeneous radioactive waste, including boron concentrates, spent resin, and sludge, should be solidified or packaged in high-integrity containers (HICs). This study investigates the sequential segmentation process for the separation of contaminated and non-contaminated regions, the re-packaging process of segmented or crushed cement-solidified boron concentrate, and re-packaging in HICs. The conceptual design evaluates the re-packaging plan for the segmented and crushed cement-solidified waste using HICs, which is acceptable in a disposal facility, and the quantity of generated HICs from the treatment process.

After independence, more introductory books on Korean culture were published in both Korea and Japan, along with various papers briefly presenting relevant materials. There are differences depending on the research field, however, a considerable number of articles about Buddhist paintings were published. Research on Korean sculpture was quite active among Japanese scholars. And numerous articles and publications on Korean painting were also presented in both Korea and Japan. Publications on Korean ceramics were increased as much as in other fields. From the late 1980's through late 1990's, research on Korean cultural properties continued to increase, as many young scholars began to conduct research very actively in Korea, producing many articles to introduce new materials. A small number of Japanese scholars also continued to research Korean cultural properties. The overall number of Korean researchers also increased, as existing scholars were joined by students who went to Japan to study and conduct research, thereby helping to significantly expand the area and topics of research. In this period, the exchange exhibitions between Korea and Japan were increased. Also the substantial research reports was began to be published by the national institution. From the early 2000 thrugh present, in all fields, research has progressed and improved since the late 1990's, with many individuals pursuing a microscopic approach to their artifacts and works. More graduate students have been focusing on Korean cultural properties in Japan as the subject of their master's or doctorial thesis in art history, and overall number of researchers in various areas has increased. In the field of Buddhist painting, painting, and Buddhist crafts some important books and articles have been published. However, research achievements have been somewhat uneven. In the area of ceramics, several significant examples of substantial research reports were published by the National Research Institute of Cultural Heritage. These publications are outstanding references that illustrate the future direction of research on Korean cultural properties in Japan.

Although development density control has received murk attention in urban planning, there has been little research on empirical methods that can examine local changes in development density. Recently, attempts have been made to develop cellular automata (CA) models that can be applied to urban landuse change. This paper aims to develop an extended landuse change model based on urban CA considering development density. The proposed model not only includes density control component in a model framework, but also directly estimates local density changes in land use. The developed model was applied to the study area, which was a part of central Seoul. The calibration of the model was carried out over the period $1900s\sim2000s$ using parcel-based land use data and related variables The results of the calibrated model have been tested by comparison with actual landuse data, and have demonstrated that the developed model can produce realistic simulations of urban landuse changes. But model output is dependent on the spacio-temporal resolution of input data. Further research is necessary to improve the calibration procedure and methods for evaluating model validity.

The need for ready-to-wear clothing increases as the problem comes to arise from the fit of custommade clothing due to the characteristics of middle-aged women's somatotype. At this point of time, a study on the realities of production of custom-made clothing in middle-aged women's clothing business firms is of very greatly significance. Therefore, this study was intended to identify the problem and improvements through the survey research of production of custom-made clothing in middle-aged women's clothing business firms and further present the plan for development of custom-made clothing business. The questionnaire was framed based on the contents extracted from the preliminary questionnaire research for the pattern section chief of each business firm. Collected data were statistically processed using the SPSS 10.0 Windows program. As a result, the following findings were obtained: 1. The target age of the middle-aged women's clothing business firms ranged from more than 45 years to less than 50 years of age. Clothing business firms much made inroads into the ready-to-wear clothing market largely in the 1980s and the 1990s. Their active entry into the custom-made clothing market occurred in the 1970s and the 1980s. 2. In terms of the clothing production method of middle-aged women's clothing firms, some private boutique and designer brand clothing firms entered the clothing market with a focus on custom-made clothing in the beginning of its organization and introduced the production method of ready-to-wear clothing in accordance with changes in production methods and consumers' needs and wants. National brand clothing firms manufactured clothing with a focus on ready-to-wear clothing from the beginning of its organization, but at last they manufactured both partial custom-made and whole custom-made as the problem arose from ready-to-wear clothing. Seeing that their clothing production showed the ratio readyto-wear to custom-made clothing of 2.58:1. And it was found that the manufacture of ready-to-wear and custom-made clothing took into consideration the great difference in the pattern, size and design plan. The research of the clothing production process showed that whole custom-made and partial custommade were distinguished according to whether or not the sample was presented. 3. The ready-to-wear pattern of middle-aged women's clothing firms were used with a focus on the 'patternmaker-developed pattern' and company-developed pattern'. Most clothing businesses produced clothing in 4 to 5 basic sizes, which is found to be insufficient to complement the physical characteristics of middle-aged women with many specific somatotypes. In the pattern of custom-made clothing, the 'pattern of ready-to-wear were applied' or the 'customized pattern was developed'. Actual measurements were most used as the size of custom-made, and accordingly it is predicted that the level of satisfaction is higher with the fit of custom-made clothing than that of ready-to-wear. The selling place and the head office showed the similar percent as the place for measuring the size of custom-made clothing. Size measurers were mostly the shop master. And it was found that most clothing business firms had a problem when the measured size was applied to the pattern. Accordingly, it is necessary to provide education on size measurement for shop masters. 4. It was found that in the middle-aged women's clothing firms, the pattern correction of the length of sleeve, jacket and slacks occupied the highest percent. Accordingly, it is necessary to provide for the size system to complement the accurate somatotype characteristics of middle-aged women. 5. In custom-made clothing customer management, most firms engaged in customer somatotype management through size management. They provided customers with commodity information by informing them of the sales and event period and practiced human management for customers by maintaining the get-together and friendly relationship. 6. Middle-aged women's clothing businesses responded that it would be necessary to improve the fit of custom-made clothing and complement their pursuit for individuality as the plan to improve its quality. In consequence, it suggests that middle-aged women's clothing businesses should provide middle-aged women with the clothing of better-suited size and refined design. Middle-aged women's clothing businesses responded that it was the most urgent task to form the custom-made clothing manufacturing team as the plan to expand the custom-made clothing market, which is identified as their emphasis on the systematized production of custom-made clothing.

This study analyzed the chronology of children's cartoon through character while the children's cartoon section is planned at the Memorial Exhibition of 100th year of Korean Cartoon which will be held at the Contemporary Art Gallery in celebration of the 100th year after birth of Korean Cartoon. The approaching method based on character is regarded as the most proper and feasible in the identification of character and meaning of children's cartoon because the character in cartoon contains the bigger role and meaning than the descriptive structure of narration. The Committee of 100th Year of Korean Cartoon, Aicheorum which is a study association for children's cartoon and Cartoon My Love $Cafe^{42)}$ in Naver jointly selected the 70 cartoon characters. A brief history is established based on these characters through chronological classification in seven sectors of around 10 year session such as before 1950s of quickening period and liberation, 1950s, 1960s, 1970s, 1000s, 1900s and after 2000. It examined the historical meaning, its reflection and characteristics focused on the cartoon character and the cartoonist which were well-known to everybody not only the display according to chronological order. The study intented the stereoscopic illumination on the children's cartoon and character which were favored beyond the generations. In addition, the similarity and human relation among cartoonist to cartoonist and character to character were analyzed and traced to identity the fact that children cartoon character is not individualistic being but it lies on the extension of tradition and trend of eternal cartoon history Finally, hopefully it will make a contribution to activate the pure creative children's cartoon in Korea through reminding the importance of character in cartoon, affirming the industrial value and reflecting the direction and perspective of pure creative children's cartoon.

This study aims at providing useful fundamental information to re-establish the theories of modern fashion by examining the origination and genealogy of street style. The street styles focusing on caucasoid have a variety of genealogies such as western type, beat, teddy boy, hippie, skinhead, punk, neuron-mantic, indie kid, riot grrrl, grunge and techno cyber punk. In the same period, on the contrary, the streets styles focusing on negroid are zootie, hipster, modernist, rude boy, two-tone, rastafarian, funky, B-boy, fly girl, raggamuffine, bhangra, and acid jazz, which are seen as the culture of the large cities formed along Atlantic Ocean and Caribbean sea like England, America and Jamaica. These have root as the main fashion in western society. Ironically, most of the subculture concentrated on the whites were racists. Because of such a reason, the street styles have been formed as resistance culture that was unable to sympathize with their society and characteristics by distinguishing the whites and the colored people. Zootie or hipster that is one of the street fashion styles was formed in the 1940-50s, while the colored people who lived in the west Indies migrated to England or America. As a minimal modernist style called Ivy look in US, in that time, anti-culture formed by teenagers in whitey, teddy boy and mods fashion can be strictly different from the zootie and hipster. The colored people's street styles of the 1960s developed into aggressive and hard forms from the rude boy and two-tone while their resistance toward the whites was stronger. The rastafarian style researched the peak as the colored people's traditional ethnic characteristics or resistance intention for their freedom in the 1970s. In that time, The colored people's street styles of the 1960s developed into aggressive and hard forms from the rude boy and two-tone while their resistance toward the whites was stronger. The rastafarian style researched the peak as the colored people's traditional ethnic characteristics or resistance intention for their freedom in the 1970s. In that time, the street styles of the whites were mostly the skinhead or hippie. Most of them were racists toward the colored people. The punk type on shown on the whites focused on luxury and exaggerative costume. On the contrary, the funky style of the colored people focused on aggressive nihilism and form. With B-boy, fly girl, reggae, rap music, and break dancing in the 1980s, the subculture gradually told on the high fashion as well as the culture between the whites and the colored people. From such aspects, the colored people tried to maintain their unique traditional characteristics. However, their individual values surged by the coming young generation excluded the colored people's characteristic street styles. Focusing on gender, violence and private success among their major concerns, the raga muffin style that represents multi-races and multi-cultures was formed. The jazz style in the 1990s showed cold post-modernistic eclecticism different from that of the 1940s-50s. Simultaneously, the various classes appeared their street styles by emphasizing on each personality. Now that we are living in multi-cultural society, a human race or nationalism concept is getting obscurer. There is no obvious boundary line in the differences between human race and its fashion.

This paper investigates the development and aesthetics of Korean political theatre from its quickening period 1920s to democratization era 1990s. Political theatre before 90s developed an antithesis resistant movement toward Korean modern history that had been scattered with suppressing political circumstances such as colonial era and dictatorial government, the movement has powerful activity and social influences. Just like the 20 century political theatre had been quickened under the influence of Marxism at Russia and Germany in 1920s, Korea's political theatre began in socialism theatre movement form around the same time. Proletarian theatre groups had been founded in Japan and Korea, and developed into practical movement with organized connection. However, the political theatre movement in Japanese colonial era was an empty vessel makes great sound but not much accomplishments. Most performance had been canceled or disapproved by suppression or censorship of the Japanese Empire. The political theatre in liberation era was the left drama inherited from Proletarian theatre of the colonial era. Korean Theatre alliance took lead the theatrical world unfold activities based on theatre popularization theory such as 'culture activists' taking a jump up the line and 'independent theatre' peeping into production spot as well as the important event, Independence Movement Day Memorial tournament theatre. Since 1947, US army military government in Korea strongly oppressed the left performances to stop and theatrical movement was ended due to many left theatrical people defection to North Korea. The political theatre in 1960s to 70s the Park regime, developed in dramatically different ways according to orthodox group and group out of power. The political theatre of institutional system handled judgment on sterile people and had indirect political theatre from that took history material and allegory technique because of censorship. In political theatre out of institution, it started outdoor theatre that has modernized traditional performance style and established deep relationship with labor spot and culture movement organizations. Madangguek(Outdoor theatre) is 'Attentive political theatre', satirizing and offending the political and social inconsistencies such as the dictatorial government's oppression and unbalanced distribution, alienation of general people, and foreign powers' pillage sharply as well as laughing at the Establishment with negative characters. The political theatre in 1980s is divided into two categories; political theatre of institutional system and Madangguek. Institutional Political theatre mainly performed in Korea Theatre Festival and the theatre group 'Yeonwoo-Moudae' led political theatre as private theatre company. Madangguek developed into an outdoor theatrical for indoor theatre capturing postcolonial historical view. Yeonwoo-Moudae theatre company produced representative political plays at 80s such as The chronicles of Han's, Birds fly away too, and so on by combining freewheeling play spirit of Madangguek and epic theatre. Political theatre was all the rage since the age of democratization started in 1987 and political materials has been freed from ban. However, political theatre was slowly declined as real socialism was crumbling and postmodernism is becoming the spirit of the times. After 90s, there are no more plays of ideology and propaganda that aim at politicization of theatre. As the age rapidly entered into the age of deideology, political theatre discourse also changed greatly. The concept 'the political' became influential as a new political possibility that stands up to neoliberalism system in the evasion of politics. Rather than reenact political issues, it experiments new political theatre that involves something political by deconstructing and reassigning audience's political sense with provocative forms, staging others and drawing discussion about it.

In order to compare the spatio-temporal variation pattern of sea surface temperature (SST) in Korea's Southern areas of the sea according to a regional scale, this study has selected the winter and summer seasons for 31 years (1980~2010) in a period aspect and selected three areas of the sea such as the Western areas of the sea (region B) and Eastern areas of the sea (region C) around Jeju Island in addition to overall Southern areas of the sea (region A) in regional aspect. The regression analysis was applied to find out a temporal variation pattern of SST, and the weighted mean center (WMC) of SST as well as analysis of a standard deviational ellipse (SDE) was respectively applied. As a result of regression analysis of SST, it showed a rising long-term trend for all two seasons in three regions. However, though the average SST for 31 years was all similar in three regions in the summer season, the region C appeared more highly than region B in the winter season. The spatial variation pattern of SST for two seasons showed that it is respectively different from each other in three regions. The spatial variation pattern of SST appeared as E-W direction in region A, SE-NW direction in region B and SW-NE direction in region C. In addition, the relationship between the location of the WMC of SST and the average SST showed correlation in regions A and B in the winter season, whereas it appeared that there is no correlation in region C. Accordingly, it can be known that the regional scale should be considered in case of analysis of spatio-temporal variation patterns of SST.
