Cloud streets were successfully simulated by numerical model (RAMS) including an isolated mountain near the coast, large sensible heat flux from the sea surface, uniform stratification and wind velocity with low Froude number (0.25) in the inflow boundary. The well developed cloud streets between a pair of convective rolls are simulated at a level of 1 km over the sea. The following five results were obtained: 1) For the formation of the pair of convective rolls, both strong static instability and a topographically induced mechanical disturbance are strongly required at the same time. 2) Strong sensible heat flux from the sea surface is the main energy source of the pair of convective rolls, and the buoyancy caused by condensation in the cloud is negligibly small. 3) The pair of convective rolls is a complex of two sub-rolls. One is the outer roll, which has a large radius, but weak circulation, and the other is the inner roll, which has a small radius, but strong circulation. The outer roll gathers a large amount of moisture by convergence in the lower marine boundary, and the inner roll transfers the convergent moisture to the upper boundary layer by strong upward motion between them. 4) The pair of inner rolls form the line-shaped cloud streets, and keep them narrow along the center-line of the domain. 5) Both by non-hydrostatic and by hydrostatic assumptions, cloud streets can be simulated. In our case, non-hydrostatic processes enhanced somewhat the formation of cloud streets. The horizontal size of the topography does not seem to be restricted to within the small scale where non-hydrostatic effects are important.

Korea is experiencing unprecedented destruction of communities and crisis of mental health represented by top suicide rate among OECD countries. Its causes are manifold of various factors. One of them is lack of social support and broken communities that are closely related to social capital that is linked to other health indicators such as mortality rates. This studies looks for ways to improve social capital through spatial structure and features especially social capital related to neighborhood. Researchers conducted research literature review and observation on physical features of neighborhood streets and alleys. Review of studies show housing types can affect social capital level. High-rise apartments are related with lower neighborhood related social capital compared to single homes and low-rise multi-housing. Studies that mainly examined the physical features such as street layout showed that social encounters happened around local stores and crossings of small roads. Researchers identified actual streets that are more likely to be related with social activities in the neighborhood. Those streets were with physical elements that helped social exchange such as narrower streets, exposed stairs, street furniture of residents, parks, crossing of streets while other streets were with wider and easier access of cars.

우리 나라의 도시화율은 2003년 현재 90%에 다다르고 있으며, 도로이용자의 요구사항은 나날이 다양해지고 있어, 도시부의 다양한 도로종류 및 기능별 설계기준을 제시하고, 이용자의 다양한 욕구를 충족시킬 수 있는 $\ulcorner$도시부 도로의 구조 시설기준$\lrcorner$ 작성이 시급한 현실이다. 이에 본 연구는 선진국의 사례와 국내의 여건을 고려한 $\ulcorner$도시부 도로의 구조 시설기준$\lrcorner$ 작성방향을 횡단면 설계를 중심으로 정립하고, 전문가 설문조사를 통하여 도시부 도로 설계지침의 필요성과 기본방향, 설계 요소 등에 대해 분석하였다. 본 연구에서는 도시부 도로설계의 가장 중요한 요소인 횡단면(cross-section)을 중심으로 미국, 일본, 독일 등 도로분야 선진국들이 갖고 있는 기준을 국내의 설계기준과 비교 분석하여 우리나라 실정에 맞는 횡단면 설계기준의 기준안 작성에 시사점을 제공하고자 하였다. 선진국의 경우, 기본적으로 다양한 횡단면 설계가 가능하도록 설계 지침서가 제공되고 있으며, 각 설계 요소별로 최소치, 중간치, 최대치 등을 제공하는 등 설계자가 도시특성에 맞게 도로를 설계할 수 있는 틀을 제공하는 것으로 나타났다. 그러나, 우리나라의 경우 도시부 도로설계시 준용되고 있는 법규 및 기준서는 다양한 도시부 도로의 설계에 적용하기에는 매우 부족하고 경직된 구조임이 파악되었다. 전문가 설문조사 결과, $\ulcorner$도시부 도로의 구조 시설기준$\lrcorner$은 각계 전문가 및 이용자의 다양한 욕구를 감안할 때 어떤 형식으로든 제정되어야 하는 것으로 나타났으며, 이는 현재 사용되어지고 있는 '도로의 구조 시설기준에 관한 규칙' 및 그 해설집이 지역간 연결도로(지방부 도로)에 대한 최소치 기준만을 제시하고 있어 이용자의 다양성과 각 도시의 특성을 표현하는 수단으로 사용되기에는 매우 부족한 것으로 진단되기 때문이다.

In this study, the modern street fashion of Kangnam and Kangbuk was qualitatively examined and comparatively analyzed through the field case study, and it is expected that the results of this study be importantly used in planning commodity of fashion brand. The photographs taken in the Kangnam and Kangbuk streets were classified as looks. which were comparatively analyzed each other. Also, a questionnaire was carried out in return for women in those streets, and data related with an age group, occupation, school, academic major, etc. for participant personality and with time purchasing clothing. average expenses for clothing per month. market and reasons for buying clothing, current fashion style, etc. for fashion preference trend were obtained. The streets around Kangnam subway station and KOEX mall for the Kangnam fashion style were selected for the sampling, and Sinchon and entrance of Ewha University for the Kangbuk, where college students and middle/high school students mostly gather. Results showed that an easy casual style was most popular in the Kangbuk area, and a romantic feminine style including a bobos style most popular in the Kangnam area. This case studied on the street fashion gaves the qualitative results about the fashion trend and fashion prediction information, and they could be compared with quantitative those known previously. Also, it could be a basis research on strengthening the competitive power in fashion commodity. However, this study was subjected to restriction in the sampling due to the short time and a few streets. This study will be extended into longer time and various streets including Apgujungdong in Kangnam and many colleges in Kangbuk.

Modern cities have been clustered with spaces defined by specific functions, while standardized with well-defined areas. The monopoly of the function reduces the publicity of the space and hinders people's daily communication. Street also be overwhelmed by the function of being a "passage", traditional streets were losing their liminality. In fact, the street was a place of meeting, a place of events, and a place of freedom to broaden the choices of behavior. The freedom to stop or walk on one'sits own, be attracted by unforeseen events that are available on traditional streets, has become rare on the streets of big cities. Life has become dull and monotonous, too, through the modelling of the street system. Cities have become grim as communities are cut off and fragmented. In today's big cities, public attention to the liminality of the traditional streets need to be aroused so that people could gather freely and have a festival time.

This study focuses on the evaluation of the streets on residential areas. For this purpose, pedestrain and vehicle occupancy indicators on residential areas are proposed, and vehicle, pedestrain flow and status of on-street parking on residential streets are analyzed. Also, according to the suggested occupancy indicator, occupancy status of pedestrain and vehicle are identified. At the end, evaluation of residential streets are conducted. The suggested occupancy indicator is a quantitative indicator which can represent the traffic situation on street. It can also be represente din the same dimension among pedestrain, vehicle flow, packed vehicle. Also, occupancy indicator can be utilized for the allocation and evaluation of transportation modes on residential street. Except on-street parking during the day time, moving vehicle occupancy rate contains the more than 80 precent when it is estimated based on the vehicle flow and pedestrain only. As the streets on residential area are occupied by the pedestrain approximately 20 percent during the day time, it is identified quantitatively that the necessity of space for pedestrain.

The purpose of this study is to interpret the townscape of Kyungju based on the urban images captured by citizens. 58 verval interviews and 50 sketch maps were collected and analized comparing with York which was a similar old city in England. In the verbal questions, elements like tombs, historic remains, families and historic values were frequently mentioned mainly because of their social and historic meaning. But in the sketch maps, physical elements like railroad station, city hall, roundabouts and streets were more frequently appeared probably because of their visibility. As a whole, many tombs which were built long ago in and around the city were commonly mentioned in verbal questions, sketch maps and even in nicknames. As the most dominant factors, it can be compared with York Minster in York. But whereas the shopping streets in York were very attractive to the people, many streets in Kyungju were regarded as dirty and inharmonious elements in townscape. In conclusion, we can call Kyungju 'the city of tombs', but to evoke the sense of place in the city the streets should be improved and activated as the center of city life.
