This technology is to let rainwater flow into a waterway that is located side gutter of a street with blocking garbage including cigarette butts at the same time. The first waterway is located beside the sidewalk and it enhances the water circulation in a city. This waterway is filled with aggregates and filter media, which removes fine dust that is washed out of the street and let water flow down to the earth. The second waterway is located beside the street and it retains rainwater temporarily with decreasing its flow speed. The second waterway shall reduce flooding damages by avoiding bottleneck situation in the street inlets and storm water pipelines which is the main causation of flooding in a city.

In order to search for ecologically indicative characteristics on the street tree plots in Daegu area, plant communities and their floras were investigated. A total of 105 plots were collected and numerically analyzed by PCoA(Principal Coordinates Analysis). These plots were classified into 4 types containing 139 species, 97 genera, 42 families(including 37 exotic species): urban-dry type, urban-wet type, rural-dry type, rural-wet type. Habitat connectivity to the surrounding vegetation cover, extent and frequency of human impacts, and soil moisture recognizably were the main factors to allow the plots differentiation. Indicative species composition to these four types was generated as Eleusine indica-Eragrostis multicaulis-Oxalis corniculata to the urban-wet, Digitaria ciliaris-Eleusine indica-Eragrostis multicaulis to the urban-dry, Setaria viri-dis-Artemisia-Lactuca indica var. laciniata to the rural-wet, and Setaria viridis-Digitaria ciliaris-Erigeron canadensis to the rural-dry, respectively. Mean species number per plot for rural type was 2.5 times higher than for urban types. Street tree species representative to the rural-wet type is Zelkova serrata, which is a key species of potential natural vegetation in the alluvial land of Daegu area. Street tree plots were characterized by Eleusine indica showing the highest r-NCD value and also C4-assimilation grass plants. Views on the efficacy of the rural-wet type and the reinforcement of vegetation connectivity and soil moisture in rehabilitating street tree plots, are discussed.

When a heavy rain occurs, many electrical shock victims are produced every year because lamp poles are under water. In order to prevent electrical shock accidents at a street lamp, the investigation was carried out at real field conditions. The investigation was performed about the circuit configuration of a panel board, a wiring method, a grounding conductor, a lamp pole and so on. The related regulation was analyzed and the problems were presented. Also, the domestic and foreign things were compared and analyzed by the investigation of the field conditions, and the related standard was already revised. Through investigating the field conditions and analyzing the related regulation, it is intended to present the real data to establish more effective preventive measures against electrical shock accidents at a street lamp to be installed on the road. In the future, the analytical data can be applied to stabilize other electrical facilities on the road as well as a street lamp, and to reduce the electrical disasters.

Public uniforms play an important role in creating the color and image of urban environment beyond the level of simple working clothes for unity and practicality. Hence this study aims to compare and analyze the color characteristics and images of the police officer, fire fighter, and street cleaner uniforms at home and abroad to guarantee the wearer's safety, increase convenience and agreeability, and give emotional satisfaction to citizens in harmony with urban environment color as public uniforms. For study methods, literature review investigated urban environment, color, and uniforms as public design. Empirical study extracted color data from the public worker uniforms of the world's top 20 cities selected by 'Newsweek' in 2010 and analyzed their colors, tones, and color images. The results of this study are as follows. The most common color for police uniforms were PB(dk) as the main color, PB(p) as the sub color, and Wh as the accent color. For fire fighter uniforms, PB(dkg) was the most common main color; GY(v), as the sub color; and ItGy, as the accent color. The most common color for street cleaner uniforms was YR(v) as the main color; GY(v), as the sub color; and mGy, as the accent color. As a result of analyzing color images of these uniforms, it was found that police uniforms commonly used a modern image; fire fighter uniforms commonly used a natural image and a cool casual image; and street cleaner uniforms commonly used a casual image. As examined above, the color of public uniforms suitable for urban environment and job characteristics is very important to establish the image of public institutions, as well as to create an urban image.

This study is an attempt to seek ways to revitalize the main streets in local city with regard to urban regeneration. It focuses on the case of Myeong-dong Fashion Street located in front of Cheonan Station, which recently lost its vitality. In order to explore causes of the decline and solutions for restore, this paper investigate the concerned urban area by approaching through three different aspects: physical and environmental aspects, social and economic aspects, historic and cultural aspects. In addition, the street visitors were surveyed on their visiting patterns, priorities and discontents about the components of street, and preferences for its restoring, etc. The investigation resulted in following findings and proposals. In physical and environmental dimension, it is needed to create legal incentives for encouraging local residents to develop their own district, and suggested to plan green space for relaxation and cultural arts space by using existing buildings, along with the expansion of public parking. In regard of social economic aspects, it is proposed to give each street specialized commercial theme. At the historic and cultural level, it is suggested to plan the pedestrian network which links the Fashion Street with surrounding historic elements.

This study is to explore how the bondage of street homeless is made and what it implies. In order to do so, this study does participation-observation for the life of the homeless on the street and drop-in-center according to the ethno-graphic research tradition. Starting from the August of 2005, during the period of six months, we did a field study on the actual conditions of facilities for the homeless in the major parts in Seoul and collected the interview data through the interview-in-depth with 8 homeless people. Following the data-analysis procedures of Spradley(1979), we identified the main domains related to the factors for the bonding of street homeless. These domains show us how the homeless people who were left in the whole new world of homelessness just manage to tide over the crisis of identity and survival. The bondage of street homeless in the situation of street homelessness has been shown to have these following meanings: (1) the cultural significance as their second home, (2) the meaning of an alternative group to be admitted, (3) the maintenance of self-identity by way of distinction in the group. According to these, the self-identity of homeless is dual and, therefore, the meaning and interpretation of their relationship is also dual. This dualistic attitude comes from the process in which the homeless acquire the alliance-resource for the very survival and self-existence. The results of this study confirm that the homeless suffer from the lack of true relationship as well as resources. This study suggests that the supporting policies and services for the street homeless should be achieved qualitatively and integrated under a long range plan.

Enlargement of street tree planting area is the proper and effective solution to reduce carbon dioxide. This solution bases on the ability of carbon storage and uptake by tree metabolism. However, the circumstance of road side has fatal disadvantages in tree metabolism such as growth and maturity because cutting and filling of roadsides cause unnatural soil composition. In this point, early rootage of street tree is the main factor of reducing carbon dioxide. This study aimed to find a appropriate transplantation planting method for sound and rapid rootage of street tree. For the study, Korean Mountain Ash(Sorbus alnifolia) were used for experimental groups. The groups were categorized by three groups such as trees produced on container with mulching treatment, trees produced in outdoor with mulching treatment, trees produced on container with weeding treatment. Each group consisted 10 trees with same size and transplanted in experimental site. Five months after transplanting, each group was estimated the biomass and carbon storage through a direct harvesting method. According to results of the study, the carbon storage of trees produced on container with mulching treatment is 42% more than trees produced in outdoor with mulching treatment. And the carbon storage of trees produced on container with mulching treatment is 19.5% more than trees produced on container with weeding treatment. These results may imply that transplantation of container produced tree with mulching treatment is the most rapid rootage among other groups. The weeding treatment is more effective than mulching treatment for rapid rootage of street trees.

This study focused on the possibility of reducing the cooling load through the change of micro climate in the outdoor space during summer season. This study proposes an efficient planning model by comparing the effects of urban heat island mitigation through wind path planning, outdoor space vegetation, and exterior material change by using the basic model of the street-oriented block housing proposed in the previous research by the same author. As a result, the most effective wind path planning strategy in the street-oriented block housing was the change of the air flow through the mass height adjustment. When the tall building masses were staggered and arranged in a balanced manner, the overall wind environment could be improved. The greater the height difference between low and high masses, the better the air flow was shown. It was also important to arrange the building masses so that the inlet of the main wind was open and to allow the external space to connect to the adjacent block to create a continuous flow. The change of outdoor space vegetation and flooring, and the formation of wind paths through the opening of lower part also showed the effect of heat island reduction. In addition, the change of PMV in summer was the biggest influence of shadow by tall building mass. Attention should be paid to the fact that high-albedo exterior materials are adversely affected by multiple reflections in dense street-oriented block housing. The use of albedo of the exterior material showed that it is necessary to pay attention to apply in the high density block housing. This is attributed to the rise of the temperature due to the absorption of energy into the low-albedo flooring, where the high-albedo exterior causes multiple reflections.
