이 논문은 거리 공연의 법적 의미와 쟁점을 검토한 것이다. 거리 공연(또는 거리 예술)의 법적 의미를 이해하는데 핵심 징표는 '공공장소'와 '예술행위'에 있다. 따라서 '공공장소에서의 예술 행위'라 할 수 있는 한, 원칙적으로 그 예술성의 수준이나 대가의 지급 여부, 공연의 규모, 예술행위의 장르를 불문하고 거리 공연 또는 거리 예술이라 할 수 있다. 거리 공연은 개방된 길거리에서 행해짐으로써 누구나 자유롭게 참여하고 예술을 즐길 수 있는 방법이다. 또 누구나 거리공연가가 될 수 있다는 점에서 거리 공연은 주류적 예술문화보다 더 대중적이고 민주적인 예술행위라 볼 수 있다. 다만 거리 공연이 유행하고 보편적 문화현상으로 자리잡아가고 있지만, 아직 법적으로 정돈되어 있는 상황은 아니라고 보인다. 하지만 거리 공연을 뭔가 이질적이면서 특별한 것으로 취급하면서 법으로 규제할 필요는 없다. 오히려 예술의 자유 등을 보장하는 헌법의 취지에 맞게 거리 공연을 자유롭게 행하고 즐길 수 있도록 내버려 두는 것이 타당하다. 거리 공연이 사회적 유해성을 가진 것이 아니기 때문이다. 최근 여러 지방자치단체들이 지역 경제를 활성화한다는 이유에서 거리공연을 적극적으로 조례로 규율하고 있지만, 거리 공연을 규율하기 위한 법률이 별도로 필요하지는 않다고 판단된다. 다만 거리 공연에 관해 제기되는 주요 쟁점별로 관련 법률을 정비하는 것은 필요하다. 예컨대 공연 무대를 설치하는 대규모 거리 공연에서 별도의 허가가 필요한지 좀 더 분명하게 규정해 줄 필요가 있으며, 거리 공연으로 인한 생활소음의 규제를 받기 위해 "소음 진동관리법"상 거리 공연에 관한 근거 규정과 소음 기준을 별도로 마련해 주는 것도 필요할 것이다. 거리 공연이 문화 현상으로 잘 정착되기 위해서는 거리공연가의 법질서 준수 노력, 거리 공연을 즐기는 시민들의 성숙된 의식과 문화적 관용태도, 그리고 거리 공연을 활성화하려는 국가와 지방자치단체의 문화국가적 보호 노력이 조화를 이루어야 할 것이다.

The ventilation performance of a street in Bangkok, Thailand, was investigated by performing measurements and conducting a CFD analysis. We focused on a street that was covered by an elevated train station. It was shown that the ventilation efficiency varied drastically depending on the angle between the street and the wind direction. When the wind direction was parallel to the street, the elevated structure had a negative influence, which created higher pollutant concentrations than in locations without elevated structures. However, when the wind direction was perpendicular to the street, the pollutant concentrations in the two situations were similar. Using a CFD analysis and ventilation performance indexes, it was shown that the elevated structure directed the wind flow and enhanced the ventilation efficiency, which positively affected ventilation performance. These kinds of knowledge can lead us to optimize city planning including high-rise buildings with high ventilation efficiency.

Optical analysis is necessary to optimize light emitting diode (LED) safety street lighting. In this study, optical analysis was conducted for 100 W LED safety street lighting. Experimental research on such a single LED was the first undertaken. Simulation modeling based on the optical properties of the single LED has compared between average road illuminances and has them analyzed with Korean Industrial Standards for LED safety street lighting (KS C7658:2009). The simulation results demonstrated that the illumination performance (average road illuminance) was 75.3 lx at a height of 4 m and an area of $32\;m^2$, 45.25 lx at a height of 5 m and an area of $72\;m^2$, and 30.05 lx at a height of 6 m and an area of $128\;m^2$. 100 W safety street lighting (model CE180-ST-OS) designed by simulation was also compared between product and 100 W simulation modeling, and error rates averaged 5.6%. The 100 W LED safety street lighting base designed in simulation modeling was proven by comparison experiments. Through the simulations and the corresponding analysis, it was found that the tested 100 W LED safety street lamp had reasonable performance. The design method for LED safety street lamps has been summarized based on the optical analysis.

Conventional HP(high pressure) sodium or Metal-halide lamps have a life span of around one year requiring at least annual replacement and maintenance. High Power LED lights require no regular maintenance further increasing savings on replacement bulbs, access equipment and labour costs. New installations benefit from a substantial reduction in the cost of expensive heavy duty cable required for sodium lighting. Especially, LED light can achieve variable color temperature, high functional performance in the field of street light. There are two main method to achieve variable color temperature function of the street light. one method is using RGB multi-chip LED, the other is using Orange-White LED method. In this paper, it was compare RGB Multi-chip LED with white-orange LED for there characteristics performance.

What is Art on the street? Is it a series of artworks or activities performed on the street? In other words, does "art on the street" refer to "Street Art" such as street performance, happening, graffiti, or wall-painting, or does it refer to "Street Furniture" which is related to "City Design" or "Environmental Design"? In a formal sense, they all belong to Art on the street. However, in this paper, I would like to use Art on the street in an even broader sense. To me, " the street" is a metaphor of "environment." Thus Art on the street is the art related to environment; it is an environment art. Art on the street attests the expansion of the concept of art and shows a new possibility of contemporary art. It is a promising new concept of art, but we cannot ignore the misapplication of the concept that we can find at the crossroad of Art on the street and "city beautification." Of course, Art on the street can and sometimes needs to beautify the city. However we still need to ask how to contribute to the city beautification with Art on the street and how to validate such a practice. City space is, most of all, a space that people live in. It sounds a cliche, but it is worth repeating to better understand Art on the street. When we consider the city space in terms of its system or organization, we often overlook that it is the space in which people live, and which people create. Art on the street concerns not the city itself, but the space in which people live and make relations for each other. Without taking this into account, Art on the street becomes a mere means to' embellish' the city and falls prey to the logic of capital. In this paper, I critically reviewed the problems such as City Development, Spectacularization, City Environmental Design, Public Interest and City Museum. I intended to emphasize that Art on the street is produced in the cultural space of city, but it also tends to break the mold of the cultural space and seeks a new possibility. Some might argue that my claims are unrealistic because Art on the street is not an idea but a practice. While humbly accepting the objection, I hope my critical suggestions guide a more productive direction to continue our discussions of Art on the street.

In this study, performance of a computational fluid dynamics (CFD) model is assessed from analysis on air flow pattern which is observed in the artificial street canyon. Field observations focusing on flows were conducted at an artificial street canyon in Magok region. For the observation of three-dimensional airflow structures, twelve three-dimensional wind anemometers (hereafter, CSAT3) were installed inside the street canyon. The street canyon was composed of two rectangular buildings with 35-m length, 4-m width, and 7-m height. The street width (distance between the buildings) is 7 m, making the street aspect ratio (defined by the ratio of building height to street width) of 1. For the observation of above-building wind, a CSAT3 was installed above the northwest-side building. Southwesterly, westerly and northwesterly were dominant in the street canyon during the observations. Because wind direction is parallel to the street canyon in the southwesterly case, westerly and northwesterly were selected as inflow directions in numerical simulations using a computational fluid dynamics model developed through the collaborative research project between National Institute of Meteorological Sciences and Seoul National University (CFD_NIMR_SNU). The observations showed that a well-structured vortex flow (skimming flow) and an evidence of a small eddy at the corner of the downwind building and ground appeared. The CFD_NIMR_SNU reproduced both the observed flow patterns reasonably well, although wind speeds inside the street canyon were underestimated.

The purpose of this study is to analyze the various types of styles and characteristics of Japanese street fashion since the 1990's. The primary source of data has been a collection of visual materials which include snapshots of young men and women in the Japanese street scene starting in the 1990's. To approach the Japanese street fashion comprehensively, I have divided the background of the Japanese fashion into three parts: 1. The birth of various fashion markets like the Dankai junior generation, Hetauma generation and Shinjinrui junior generation. 2. The pursuit of fashion senses like the well-balanced sense of independence and commensalism, uncommon sense and sense of a tassel. 3. A boom in new fashion business types like SPA and select shop. After the 1990's, the Japanese street fashion has changed through the popularity of styles which include the conservative casual style, sexy casual style, Harajuku pop style, and 3 Re(revival, remake, recycle) fashion style. The characteristics of the Japanese street fashion reflects the performance of virtual reality, the sign of style culture, and the communication of process.
