Background and objective: Urban street trees play an important role in carbon reduction in cities where greenspace is scarce. There are ongoing studies on carbon reduction by street trees. However, information on the carbon reduction capacity of street trees based on field surveys is still limited. This study aimed to quantify carbon uptake and storage by urban street trees and suggest a method to improve planting of trees in order to increase their carbon reduction capacity. Methods: The cities selected were Sejong, Chungju, and Jeonju among cities without research on carbon reduction, considering the regional distribution in Korea. In the cities, 155 sample sites were selected using systematic sampling to conduct a field survey on street environments and planting structures. The surveyed data included tree species, diameter at breast height (DBH), diameter at root collar (DRC), height, crown width, and vertical structures. The carbon uptake and storage per tree were calculated using the quantification models developed for the urban trees of each species. Results: The average carbon uptake and storage of street trees were approximately 7.2 ± 0.6 kg/tree/yr and 87.1 ± 10.2 kg/tree, respectively. The key factors determining carbon uptake and storage were tree size, vertical structure, the composition of tree species, and growth conditions. The annual total carbon uptake and storage were approximately 1,135.8 tons and 22,737.8 tons, respectively. The total carbon uptake was about the same amount as carbon emitted by 2,272 vehicles a year. Conclusion: This study has significance in providing the basic unit to quantify carbon uptake and storage of street trees based on field surveys. To improve the carbon reduction capacity of street trees, it is necessary to consider planning strategies such as securing and extending available grounds and spaces for high-density street trees with a multi-layered structure.

The purpose of this study was to analyze the changes and characteristics of street fashion in Japan of the 1980s. The data were collected from the Mainichi Newspaper published in Japan from 1950 to 1990. The results were as follows: 1. After world war II, the street fashion had changed through the styles of the Panpan, Apres, Miyuki, Hippie & Hooten, Bikers in Japan. 2. The 1980s was characterized as an era of post industrial society and the appearance of Shinjinrui which means new human. In street fashion, these changes led to greater focus on unique style in Japan. In the 1980s, the street fashion had developed within four styles : traditional casual wear style, American sports wear style, performance.oriented style, and Japanese DC brand style in Japan.

In this paper, we propose a system for controlling the brightness of street lights by predicting pedestrian paths, identifying the position of pedestrians with motion sensing sensors and obtaining motion vectors based on past walking directions, then predicting pedestrian paths through the route prediction smart street lighting system. In addition, by using motion vector data, the pre-treatment process using linear interpolation method and the fuzzy system and neural network system were designed in parallel structure to increase efficiency and the rough set was used to correct errors. It is expected that the system proposed in this paper will be effective in securing the safety of pedestrians and reducing light pollution and energy by predicting the path of pedestrians in the detection of movement of pedestrians and in conjunction with smart street lightings.

To investigate the building wind characteristics of skyscraper nearby areas, two points were selected and the wind speed and the wind direction data were measured using 2-D ultrasonic anemometer and propeller type wind monitor during the winter time. The study site is Dohgok-dong, Seoul. After measurement, wind data whose speed is equal to or more than Beaufort level five were selected, classified and analyzed in terms of direction, velocity level and hourly difference. The prevailing wind point is higher than street canyon in terms of intensity and frequency. The main direction is also different. This study aims to figure out the phenomena of building wind impact and also to provide essential basic data for establishing proper guidelines in building wind impact assessment for skyscrapers in Korea.

도시지역의 가로수는 보행자와 운전자에게 쾌적한 환경을 제공하며 탄소를 흡수하는 중요한 역할을 수행한다. 따라서 가로수의 위치, 수고, 수관폭 등에 대한 효율적인 획득과 관리가 필요하다. 본 연구는 항공라이다 자료를 이용하여 도시지역 가로수에 대한 개수, 위치, 수고, 수관폭의 수치적인 정보를 추출하는 방법론을 제안하였다. 가로수는 그 형태와 크기가 다를 수 있기 때문에 본 연구에서는 수관폭의 크기를 변화시키면서 가로수를 추출하는 방법을 제안하였다. 또한 가로수는 일반적으로 도로변을 중심으로 식재되기 때문에 이러한 식재위치의 직선적 특성을 이용하여 가로수점들을 선택하였다. 오산시 일부를 대상으로 가로수 추출에 대한 실험을 수행하였으며 결과는 1/1,000 수치지도와 비교하여 제안한 방법론의 적합성을 평가하였다. 실험 결과를 통해서, 가로수의 위치오차는 최소 0.5m, 최대 1.9m, 그리고 평균제곱근오차는 약 ${\pm}0.4m$를 나타냈다.

This study analyzes the recognition of commercial business men and employers who operate the commercial zone along the streets in the downtown area on the planting for the roadside green space forming the important frame of greening in the downtown among the open spaces. Through the analysis, this study attempts to get the basic data to suggest the recommendable directions in planting and managing the street trees in the downtown. The results of this study are summarized as described below. The street green spaces are very important in improving the environment of the downtown and their necessities are also very critical. It was found that the street trees were recognized as the critical factor to enhance the aesthetical values of the city, provide the green shades and purify the air. This study also identified that the street trees have the positive impacts on the business environment rather than negative impacts. In maintaining the street green spaces, the most necessity is the service facility such as resting areas, toilets and garbage bins with the street trees. The commercial business men and employers who operate the businesses along the streets preferred the double layer type that the tall trees and green walls are planted together along the streets for the street planting. For securing the green shades in the city, the planting of linear green spaces such as streets and waterways is critical. Moreover, the street trees accounts for the important position in the urban open spaces. The majority of commercial business men and employers consider the participation of citizens for greening as the very essential factor.

본 연구는 대구시내 국지도로의 노상주차장 설치에 영향을 미치는 요인을 파악하여 노상주차장의 설치가 필요한 지역을 선정하고, 도로의 신설 또는 확폭시 합리적인 계획 폭원을 제시하기 위한 기초적인 연구로서 12개 시범지역의 교통환경을 분석하였다. 교통량과 보행량을 제외하고 노상주차에 영향을 미치는 요인의 대부분이 계량화되지 않은 정성적인 자료이고, 종속변수인 노상주차장의 설치 유무도 질적인 자료이므로 수량화 이론II류의 분석방법을 사용하여 종속변수에 크게 영향을 미치는 요인을 분석하였고, 수집된 자료의 상관성을 검토하기 위해 판별분석을 시행하여 그 적중률을 분석하였다. 분석결과 국지도로상에서 노상주차장의 설치에 가장 큰 영향을 미치는 요인은 도로 폭원, 교통량, 보행자수, 노점상 등 상가적치물과 불법주차차량의 유무인 것으로 나타났다. 따라서 도로의 신설 또는 확폭시 단지나 건축물내 발생 교통량과 통행량 분석과 인근지역의 노점상 점유와 불법주차 정도를 파악하여, 노상주차장 설치 여부를 결정하고 이에 적절한 도로 폭원을 계획해야 할 것이다.

The purpose of this study was to suggest the most appropriate design concepts for sportive fashion product based on the analysis of consumers' acceptance of the recent sportive fashion trends according to their lifestyle. The subjects consisted of 295 males and females, between 17 and 35 year-old. A self-report questionnaire with 4 stimuli was employed for data gathering, and the data were analyzed by the methods of frequency, factor analysis, cluster analysis, and Pearson's correlation coefficient. The results of this study were summarized as follows: For the First, the recent sportive fashion trends were categorized into four groups; 'street- sportive' trend, 'futuristic-sportive' trend, 'ethnic-sportive' trend and 'urban-utility sportive' trend. Secondly, based on the result of cluster analysis on consumers' lifestyle, total four consumer groups were identified; 'pursuing sense' group, 'pursuing culture' group, 'pursuing utility' group, and 'indifference' group. Thirdly, the consumers relatively preferred two sportive styles among the four groups, typically representing 'urban-utility' trend and 'street' trend. The typical 'urban-utility' style was particularly preferred by the consumers who desired to express themselves as urban, modern, and luxurious. The typical 'street' style was preferred by the consumers who tried to express themselves as active and fashionable. Finally, preferences of the sportive trends according to consumers' lifestyle were interpreted as follows: the 'pursuing sense' group relatively preferred 'urbanutility' style and 'street' style, the 'pursuing culture' group preferred 'street' style and the 'pursuing utility' group preferred 'urban-utility' style, meaningwhile the 'indifference' group preferred 'street' style and 'urban- utility' style.
