This paper aims to develop an integrated urban freeway exit-intersection actuated traffic signal control strategy based on which a real-time detection of queue at each of an exit-ramp and an arterial. To evaluate effects of the proposed actuated traffic signal control according to various traffic situations and geometric conditions, this paper analyzed the effects of the proposed traffic signal control strategy according to traffic situations such as the occasion of the arterial being saturated, the occasion of the exit-ramp being saturated, and the occasion of both the arterial and the exit-ramp being saturated. To reflect geometric conditions that influence the effects of the control strategy, this paper evaluated effects before and after applying the actuated traffic signal control strategy according to six cases for both above and under the downstream link length of 200m as proposed by COSMOS. The study results shown that when the link length above 200m, offered a greater effect of applying the actuated traffic control strategy than below 200m. Thus, the actuated traffic signal control through a real-time detection of queue is expected to offer a greater effect at longer downward link.

In this paper the self-organized and fuzzy inference used stochastic gradient ascent method is proposed. Fuzzy rule and fuzzy set increase as occasion demands autonomously according to the observation information. And two rules(or two fuzzy sets)becoming to be similar each other as progress of learning are unified. This unification causes the reduction of a number of parameters and learning time. Using fuzzy inference and making a rule with an appropriate state division, our proposed method makes it possible to construct a robust reinforcement learning system.

Ten years have passed since my last visit to Korea on the occasion of the International Symposium on High Speed Rail Systems organized by the Korean Transport Institute in October 1989. At that time, it was the objective to introduce the maglev and VHSR (very high speed rail) systems with their different areas of application and to discuss them with local partners against the background of the Seoul-Pusan HSR project. Congratulations on the success of the Centennial seminar. I am much pleased to be invited to the memorable seminar and I would like to express my sincere gratitude to Korean members' hospitality.

Social reactions to body exposure in American leisure wear (bathing suits, shorts, and halters) in the 1930s were analyzed to provide an understanding of the process of adopting more abbreviated and less-occasion specific styles of garments in women's fashion. The research questions were as follow: How did women expose their bodies in leisure wear during the 1930s? How did the social reaction to women's body exposure in leisure wear change throughout the 1930s? How did the body exposure in women's leisure wear play a significant role in the history of women's fashion? Primary sources were collected from issues of The New York Times published in the 1930s. Topics including dress, fashion, ethics, social ethics, and sexual ethics, were reviewed in The New York Times indices. The findings were analyzed and interpreted with reference to secondary sources that included books and research papers. The results showed that the body exposure of the styles as well as the place where these styles were worn was a public issue. Women were criticized and regulated for body exposure as well as for wearing bathing suits, shorts, and halters on the streets. However, the social regulations that restricted bathing suit styles almost disappeared by the end of the decade. This represented the change of social expectations toward body exposure in the 1930s. In addition, reports of laws that forbade the wearing of bathing suits, halters, and shorts outside of beaches, pools, and parks indicated women's increased attempts to expose their bodies in public places. However, reactions to women's body exposure in leisure wear changed to accept more flexibility in the social customs throughout the decade. These phenomena were a partial step toward the popularization of less occasion-specific styles - sportswear - that took place in the 20th century.

According to the fast supply of the SMART device, many people have a lot of interests about SMART education. The Korean government is showing a lot of effort towards the promotion of SMART education. In this study, I developed a behavioral assessments and QR code based mobile web application for school education. The developed system works seamlessly across all popular mobile device platforms and if you save the data after the assessment, this system will automatically create each person's mobile web page. Students and teachers can add comments to this page and can improve the accessibility for finding the address of this page to QR code. The developed system can contribute to the class members understanding the personality of each other and make communication run smoothly. As a result of application of developed system, it is expected to contribute to increasing the interaction between a students, parents and teachers because the developed system provides a service based to education consumer's TPO(Time, Place, Occasion).

The objective of this study was to trace and to examine costume terminologies recorded in Pak Tong Sa Eun Hae. Names of costumes and costume related terms were collected from P마 Tong Sa Eun Hae. Books and various references from China and Korea were used for this study. Costume terms were examined from the Chinese and Korean. Classifications of costume terminologies from the data were made for the analysis : man and woman's costume, accessories, names of fabrics, colors, and decorative motifs used, professional costume, special occasion dresses and so on. Conclusions and summary of results and findings can be summerized as follows : It revealed that manes of man's costume and other costume related words were a large in number compared with those of woman. Only one name of woman's costume appeared in the text : It was kind of long vests. However, names of accessories such as a hat, a hat decorated with jewels and phoenix design, a hair pin, earings, bracelets, finger rings, a soft belt were shown in the text. While many costume names of man included in the text were of garments such as a kind of long vest, a short vest, an outer robe, a kind of long coat with pleated skirt, leg coverings, outer jacket and so on. Also names of undergarments such as an under skirt, a belly covering, and drawers were found in the text. Fabric names were mostly silks such as brocade, twill, sarcenet, damasks and plain silks. Blue was the most widely appeared fabric color in the text and red was the second. Design motifs of fabric design were of dragon, flowers, eight precious things, clouds which were characteristic design motifs of the Chinese. It was found that some of the Chinese costume terminologies were translated into the Korean although many Chinese costume terms were used as the original Chinese.

Recently, it appears several counterproposals about desirable figures of urban architecture. All of them proposes 'publicity' with cohernt tendency. The reason why it concentrates quantitative expansion of city without united design by urban plannar is that neglect quality values of city. As a solution of poor environment, there cue out the various efforts, about problem of each building, problem of city space, problem of laws and so forth. The reason why necessity of public space was embossed in that architecture extend the activity of citizen and make up the city space. But, each building pursues the private interest, so it is difficult to secure a public space with a high hand. Thus, architecture law has been revised in 1991 and bring the system of open space to match up the publicity and the private interest. Actually, western country brought it and obtained excellent results. While quantity of open space have increased since 1991, a lot of problems revealed in real usage and quality. By means of problem's solution, this study focus on the diversion of recognition for necessity of various open space. In result, on the occasion of approach and openess, except for several building, most glass a facade and the pedestrian can approach easily. Moreover, office buildings near the subway station connected with their low floor. So, the office buildings give openess to pedestrian and a people can approach easily to the buildings. On the occasion of amenity, most have bank and lobby on the first floor and have facilities on the underground floor. It leave open. But the reason why they have bank and lobby is that the space is dry and boring(without elements of nature and rest space). Hence, to make a space full of vitality, it have to plan various design elements and facilities. First of all, plan of indoor public space have to make up facility for the public interest. This study is basic investigation for necessity of indoor public space and through the survey of office buildings, it analyze the character of plan and find out the method of publicity's realization.
