This study has surveyed and analyzed in 2005 S/S domestic men's street fashion by using the Web-SFAS system that was developed and completed in the earlier research. Total of 270 men who were sensitive to fashion were surveyed around 5 nationwide cities and 9 commercial zones. The analysis results of the questionnaire and image survey in 2005 S/S for each commercial zone was shown as follows. 1. The most interest in producing fashionable shape when they go out was in the order of clothes>hair style>shoes and it was found that the proper reason for visiting the commercial zone was to meet with friends>watching movies>shopping etc. 2. T-shirts were most preferred as upper garments and as for bottoms, blue jeans were preferred. Black, gray, and white colors were most preferred and blue color was most preferred primarily due to the preference for blue jeans. The color image was proven mainly modem and light tone, comfortable and casual items were preferred. An active comfort casual image emphasized with activeness by coordinating comfortable T-shirts or shirts with blue jeans were most preferred in 9 areas. 3. A clear difference was confirmed in color by commercial area. Blackish color was most prevalent in Daehakro whereas simple color was mostly shown around Hongik University area. Bright and unique colors such as green and violate were dominant at Dae-Gu Dongseongro, and basic colors such as white and black were preferred in Masan Hapseong-dong and Changwon Sangnam-dong. Through the results of nationwide street fashion survey, the each commercial zone has unique characteristics in fashion trend even in the same city, rather than the regional difference in Seoul and local city.

In this paper, proposed a new lighting control system which can reduce power consumption compared to conventional street lamps and intelligently control the light efficiently depending on whether there is a vehicle on the street. The new lighting control system proposed by this paper detects the presence of cars by collecting and analyzing sounds generated by the movement of cars. Then, the system controls lighting of street lamps based on the above car detection information, and turns on the street lamps sequentially by transmitting the car detection information. Experimental results showed that lightings were controlled based on the presence of cars and that operations of the lamps were made by turning on the lights sequentially by determining the moving direction of cars. This system is considered a technology that can reduce energies by applying to local roads with a few cars moving or national highways where lights are always turned on with low energy efficiency.

The purpose of this study is to obtain specific data about the characteristics of color preference on Women's street fashion within China and Korea. Photos of Women's street fashion from the twenties and thirties were taken in person in four cities in China(Beijing, Dalian, Qingdao and Nanjing) and Seoul from July 2nd to August 10th, 2015. Three hundred photos in each city were selected, making a total of 1,500 photos. In the analysis of the colors of the clothing in these five cities, the uses of the multi color was most frequent in Dalian, while those of Black was most prevalent in Beijing, Qingdao, Nanjing and Seoul. The Black proved to be commonly preferred through all the items, regardless of terms of the nationality, areas and seasonal changes. The high incidence of Purple Blue color in Beijing, Dalian and Qingdao might be attributed to their preference of the blue jeans. The Multi color was highly shown in all the cities which might be due to their preference of compound colors rather than the mono ones. The high preference for the chromatic colors such as Red, Yellow Red and Yellow might be ascribed to the Chinese traditional color preferences. The differences lies in the color tones, such as the dark and light grayish tone emphasized in Seoul and Nanjing, and vivid and strong tones in Beijing, Dalian and Qingdao. Seoul shows a liking for the achromatic colors, preferring dark and grayish tones, compared with four cities in China, only Nanjing has a similar trend to Seoul. This study analyzes geographical preferences in China that possibly contribute to the launching of Korean fashion brands in view of the design and marketing as a useful basic resources.

This study reveals the absence of standard design guidelines by region through investigation and analysis centered on public design cases by region in Jeollabuk-do and design elements that can reflect the integration, identity, and diversity of public design in each region by five regions. Through this, the following conclusions could be obtained. First, to improve the quality of street facilities in Jeollabuk-do, the design elements (design motif, color, pattern) applicable to the standard design were analyzed by dividing them into five regions. As a design motif, it was possible to extract patterns containing straight lines, sophistication, dignity, and smartness. In the Northeast region, it is comfortable with the motif of the mountain ridge reflecting geographical characteristics, and it can be extracted elements that contain warm and natural colors. In the southeastern region, patterns that reflect design elements were extracted by applying safe, lively, and peaceful colors with the design motif of curves that blend nature and agriculture. In the southwestern region, design pattern elements that highlight nature, history, and culture were extracted with various cultural assets and natural greenery as motifs. Lastly, in the Saemangeum region, the ocean flow and greenery could be used as a design motif to reflect a positive, clear, future-oriented image in the design spot zones by region. Second, based on the standard design elements (design motive, color, pattern) by region extracted for the standard design development of street facilities in each region in Jeollabuk-do, an integrated zone(Form, structure, material, color, functional element) to which regional design guidelines can be applied. Third, an integrated zone (form, structure, material, color, functional elements) was composed. In addition, design spot zones (patterns and colors in city and county units) that can contain the diversity and identity of each region were designated. By designating design spot zones (patterns and colors in city and county units) that can contain the diversity and identity of each region, standard design development plans (integrated pillars, jaywalking prevention fences, roundabouts (urban type, rural type), street trees) Eight standard designs, including protective covers, street planters, flat benches, light benches, visual media for user guidance, and parking zones for personal mobile devices) were presented.

Lighting for outdoor advertising is very common feature of building facades as they provide the information and commercial identification. As the interest of improving street beautification more widely, application of various lighting technologies has been develop for advertisement such as electric sign board and signage. Furthermore, the installation of higher sign luminance than needed has many negative consequences, including higher energy consumption and light pollution. There are now no standard for outdoor advertisements in terms of luminance, and installation of indiscreet outdoor advertisement without luminance consideration is becoming more commonplace. This study was to evaluate the luminous characteristics of outdoor advertising as a function of sign and building facade luminance, luminance ratio. Data were collected on 8 electric sign boards, 20 internally illuminated, externally illuminated, neon, and channel letter signs and 4 commercial areas. Photometric measurements were taken by CS-100(Minolta) and ProMetric-1400(Radiant Imaging) for various sign modes and sign design. Also luminance of building facades were analyzed according with CIE standard of maximum obtrusive light permitted for exterior lighting installations. The findings are as follows; (1) There were excessive luminance of electric sign boards that could affect adjacent building facade and night sky luminance. (2) Sings that are externally illuminated providing an inappropriate amount of light on to the outer surface of the sign caused higher building facade luminance and potential of unnecessary glare.

Due to climate change and urbanization, abnormally high temperatures and heat waves are expected to increase in urban and deteriorate thermal comfort. Planting of street trees and changing the albedo of urban surfaces are the strategies for mitigating the thermal environment of urban, and both of these strategies affect the exposure and blocking of radiative fluxes to pedestrians. After measuring the shortwave and longwave radiation according to the ground surface with different albedo and the presence of street trees using the CNR4 net radiometer, this study analyzed the relationship between this two strategies in terms of thermal environment mitigation by calculating the MRT(Mean Radiant Temperature) of each environment. As a result of comparing the difference between the downward shortwave radiation measured under the right tree and at the control, the shortwave radiation blocking effect of the tree increased as the downward shortwave radiation increased. During daytime hours (from 11 am to 3 pm), the MRT difference caused by the albedo difference(The albedo of the surfaces are 0.479 and 0.131, respectively.) on surfaces with no tree is approximately 3.58℃. When tree is present, the MRT difference caused by the albedo difference is approximately 0.49℃. In addition, in the case of the light-colored ground surface with high albedo, the surface temperature was low and the range of temperature change was lower than the surrounding surface with low albedo. This result shows that the urban thermal environment can be midigate through the planting of street trees, and that the ground surface with high albedo can be considered for short pedestrians. These results can be utilized in planning street and open space in urban by choosing surfaces with high albedo along with the shading effect of vegetation, considering the use by various users.
