This study examines the process of urban formation in the city of Yanji. The analysis is done by the change of street pattern and major facility location in a timely manner by appling space syntax method. This research categorizes the pattern of the urban growth focused on two urban forms, street and major buildings, in the city and is offered of the meaning of the first value on interpretation of the urban growth in the city of Yanji. The result of the research are as follows. First, the period of the city transformation is divided into four stage; intuitive period, grid-iron formative period, consolidation period, and urban expansion period. Second, characteristics of each stage have been analyzed. At the first stage, the city started to frame along both buildings and streets which were placed without a plan. At the second stage, the city was planned and constructed into new grid-iron pattern ignoring existing context by Jananese colony. At the consolidation period, the road system expands from the city center toward suburban. At the last expansion period, the shape of the city has complicated its shape with complex road system. This study contributes to provide a basic analysis and data to investigate how the Yanji city has evolved over period of time. But further continuous research should be done for future urban development of the Yanji city.

This study concern with the changes of street from the Choseon Dynasty to present days around Old-Boundary in Taegu, analyzing the backgrounds of change factors and development trends of the Taegu City. The basis element of a city structure is the street. Therefore, in this study, a chage of street space of a city was investigted. Historically, Taegu was a walled city and had a Mono-nucleus which was restricted by the castle, and served as a starting point of formation of spatial structuure. The form of the artery street took a "T" pattern, othe streets were formed in irregular shapes. As the city grew gradually, the castle was removed on account of diversification in traffic network, change of socio-economic organization in traffic network, change of socio-economic organization, formation of industrial bases and functional distribution. CBD of this city has been located within the area surrounded by these streets. This is a kind of general pattern of traditional walled cities through the world in both Western and Oriental societies. A s the begining of this centry, a 'Dark Ages' descended upon Korea because the country was under the Japanese-Korean Annexation, and, throughout this period, the urban planning was planned exclusively for Japanese. The street pattern within residential areas of Korea took the maze type, in contrast with Japanese residential areas which showed grid pattern of streets. This is another general pattern of almost of all colonial cities especially in Asia. High class residential areas were planned and built by Japanese, and they were located within 5-10 minutes' on-foot distance from the CBD hard core. This high prestige has continued until the 1980s when it occurred land use succession which commerical functions invaded into residential areas. Back in the colonial period, there was a between two hetrogeneous groups due to the fact that the Japanese lived mainly oriented the new railway system but that Koreans still lived along the old highway system which ran through the Korea Peninsula. Street netwook formed in the above process has maintained its shape without great changes after the liberation form the Japanese Colony. Taegu has, accordingly, developed ring-radial network system which has been a combination of radial and ring facilities. The present conditions of street patterns in Taegy mainly depend on 4 rings and 8 radius, with grid pattern street able to be found in Old Boundary.

An oscillating foil can produce a driving force through the generation of a reversed $K\'{a}rm\'{a}n$ vortex street, and it can be expected to be a new highly effective propulsion system. A simple pitching foil model was made and it was operated within a water channel. The wake formation behind a pitching foil was visualized and unsteady fluid forces were measured using a 6-axis force sensor based on force and moment detectors. We have been examined various conditions such as reduced frequency, amplitude and pivot point in NACA 0010. The results showed that thrust coefficients increased with a reduced frequency. We also presented the experimental results on the characteristics of a pitching foil at various parameters.

The purpose of this study was to analyze the formation and change of road-block-lot of the old inner city in cheongju The result of this study are as follows; (I)Among others a system roads of in around the old castle in cheongju city is most of feature north and south direction of road. Lot system is organic relations of north and south direction of road. Therefore, urban tissue in around the old castle in cheongju city is established order road system keep on the change of expansion urban tissue. (2) Block type classified into non-division, 2division and over 3division. (3) The square block remains mostly in Cheongju old castle, two-division block was around south of castle. And block of the grid-form street system divided into over 3 division. Through the guideline about characteristic of block type, residential area should be developed as a characteristics area in the urban area.

This study suggests a conceptualization model of 'cultural inclusiveness' organically connected to social inclusiveness, by expanding the implications of urban inclusiveness to the domain and relationship. Based on the process of necessity of relation, connection of space, and execution of act, the cultural inclusiveness could be connected to the formation of organic/learning relation, the creation of openness focusing on public space, and the practice of diverse subjects. Concretely, the concept of cultural inclusiveness is applied to the case of 'Hongdae-ap'. The recent Hongdae-ap is showing the value of coexistence such as the establishment of environment that could protect the diversity of individual subjects and groups(artists, residents, government officials, students, cultural activists, citizens, tourists, and etc.), the formation of public space such as 'Hongdae-up playground', 'pedestrian-friendly street', and 'Gyeongui-Line book street', social network service & horizontal network, and access.

The consumers, who are characterized by gathering a wide scope of information and by putting into action immediately, have come to the new group searching for emotion and have played a leading role of market. The characgeristics of consumers are the fact that they have followed the street fashion with no-concept, independent of the trends which the brand has provide for consumers. Therefore it leads to a big gap between the fashion information for enterprises and market formation for consumer class. The principal purpose of this paper is to get closer the distance between the information which is used in merchandise plan and real market for consumers, and to suggest the new direction of information management system in order to enhance the hit rate of merchandise plan. The results are as follows : (1) It is shown the enterprises should divide the information data between fashion information and market information, and understand the mutual relationship of them, and regard the statistical data related on the change of sensitivity and desire in market specialized in attributes of street fashion as the emotional expression\`s view, and manage them by the feedback style. (2) It is shown that enterprises should fully understand the fashion factors in the line of fashion stream with the independence of theme in order to plan the merchandise effectively for market which are specialized in the duality that it has both conservation and innovation at the same time, and detect their change. (3) It is shown that in order to predict exactly, enterprises should reflect the statistical data and the emotional factors in planning the merchandise, bring up the systematic organization, expert system. (4) It is also shown that enterprises should make an effort to pursuit the discriminated brand through the feedback management in which the consumer\`s lasting desires are reflected.

The formation and development conditions of the cloud streets over the yellow sea by the Cold Surge of Siberian Anticyclone Expansion which produce the heavy snowfall events over the southwestern coast, Honam District of the Korean peninsula, has been investigated through analyses of the three dimensional snow cloud structures by using the CAPPI, RHI, VAD and VVP data of X-band Radar at Muan Weather Observatory and S-band Radar at Jindo Weather Station. The data to be used are obtained from January 04, 2003, when heavy snow storm hits on Gwangju and Honam District. The PPI Radar images show that the cloud bands distribute in perpendicular to the expansion direction of the high pressure and that the radius of cloud cells is about 5~8 km with 20~30 dBz and distance between each cell is about 10 km. And but the vertical Radar images show that the cloud street is a small scale convective type cloud within height of about 3 km where a stable layer exists. From the VVP images, the time period of the high pressure expansion, the moving direction and development stages of the system are delineated. Finally, the vertical distribution of wind direction is fairly constants, while the wind speed sheer increases with altitude to 3 km.

A city is a type of culture as living styles people have accumulated, In Particular, urban streets are integrated bodies of culture based on regional history and tradition which are easily accessible by people. However, due to insensible expansion policy of current cities, decline of old downtowns which have kept cultural characteristics of each region, hollowing out of the downtowns, expansion of new downtowns which have uniformed characteristics are weakening identities of each region. To overcome such problems, a culture-oriented approach as one of the urban regeneration strategies which have been appeared since 1980s is effective. Life style which has been formed by human activities can be considered as the culture of comprehensive concept and peculiar resources of each region are distinctive culture of each region. Cultural streets in which people can share each other's feeling may influence regional activation through cultural influence while preserving regional tradition and history. Therefore, this study aims to discover spatial characteristics of cultural streets through theoretical examinations on formation of streets in as aspect of urban regeneration and identify their characteristics by analyzed cases of domestic cultural streets.

Oscillating foil propulsion, the engineering application of fish-like movement of a hydrofoil, has received in recent decades as a possible competitor for propellers. The oscillating foil produces an effective angle of attack, resulting in a normal force vector with thrust and lift components, and it can be expected to be a new highly effective propulsion system. We have explored propulsion hydrodynamics as a concept in wake flow pattern. The present study has been examined various conditions such as oscillating frequencies and amplitudes in NACA0010 profile. Flow visualizations showed that high thrust was associated with the generation of moderately strong vortices, which subsequently combine with trailing-edge vorticity leading to the formation of a reverse $K\acute{a}rm\acute{a}n$ vortex street. Vortex generation was inherent to jet production and playeda fundamental role in the wake dynamics. And it was shown that the strong thrust coefficient obtained as the Strouhal number was larger.
