Passenger safety is a primary concern of railway system but, it has been urgent issue that dozens of people are killed every year when they are fallen from train platforms. In this paper, we propose a vision based monitoring system for railway station platform. The system immediately perceives dangerous factors of passengers on the platform by using image processing technology. To monitor almost entire length of the track line in the platform, we use several video cameras. Each camera conducts surveillance its own preset monitoring area whether human or dangerous object was fallen in the area. Moreover, to deal with the accident immediately, the system provides local station, central control room employees and train driver with the video information about the accident situation including alarm message. This paper introduces the system overview and detection process with experimental results. According to the results, we expect the proposed system will play a key role for establishing highly intelligent monitoring system in railway.

The purposes of this study were to identify dimensions of shopping orientation and preferences of fashion trade areas, to test differences in the preference factors and usage levels of fashion trade areas as determined by shopping orientation and demographic characteristics. Questionnaires were administered to 406 adults in their twenties and thirties visited major fashion trade area in Seoul. The results of the study were as follows. First, five groups were identified based on shopping orientation: combined value-oriented group, convenience-oriented group, hedonic value trend-oriented group, economic-value oriented group and brand-oriented group. Second, the most frequently visited trade area was Myungdong, and there were significant differences in the usage levels of the trade areas except Dongdaemun, Samsung station COEX, Jamsil and Gangnam Express Bus Terminal among the groups determined by shopping orientation. Sinsa Garosoogil, Apgujeong Chungdam and Samsung Station COEX were preferred by hedonic value trend-oriented group. Daehakro and Myungdong were preferred by combined value-oriented group and convenience-oriented group. Third, significant differences were also found in all groups in the preference factors of the trade area as determined by shopping orientation groups when purchasing clothing. Forth, female preferred Gangnam Express Bus Station and Jamsil than male did. Those who in their early twenties preferred Daehakro and Myungdong the most and those who in early thirties and late twenties concerned service policy the most. The results imply that the consumers tend to visit the nearest fashion trade area by their residence(or work, school) and consider the location and accessibility of the trade area as the most important factor.

This study aims to identify the Spatial Changes and the main agent of space creation in Samrye Area during the Japanese Occupation Period. As for the urban space in the Samrye area, the urban space was expanded to the Hujeong-ri area from the construction of the Jeonbuk light railway. Before 1914, the urban space of Samrye was formed around Samrye Station in Samrye-ri, which oversees Samrye-do from the Goryeo Dynasty to the Joseon Dynasty, but when Samrye Station of Jeonbuk light railway was established in Hujeong-ri in 1914, the foundation of a ladder-type street network visible from the central space of the current Samrye area was formed until the 1930s. And it was the Japanese and Korean landowners who took the lead in the construction of the Jeonbuk light railway, not the government, who expanded the urban space of Samnye from Samrye-ri to Hujeong-ri. The background of the establishment of Jeonbuk light railway is the reason why Dongsan Farm has difficulty in transporting rice to the Honam Line during the rice harvest. At that time, Park Ki-soon, famous as the land king, took charge of the established chairman of the railroad installation and established it, and with the establishment of Samrye Station, the access road was connected to his farm. In addition, a new road was built on the farm land that owned the Hujeong-ri area to the Seoul-Mokpo Interroad in Samrye-ri, thereby expanding the urban space. In other words, unlike Gunsan and Iksan, which were built under the leadership of the Japanese colonial eran government, the urban space in Samrye area was expanded by a farmer who grew up as a large landowner based on agriculture, which was the economic base at the time.

In urban areas, the proportion of railway traffic in public transport is increasing. The congestion situation is repeated as the passengers concentrate on station and transfer facilities and the inconvenience of the passengers is increasing in terms of safety and convenience. Therefore, the importance of estimating the appropriate area of the station has been emphasized. The area estimation formula used in the metropolitan railway stations currently is a partial modification of the area estimation formula of Japan in the 1970s. It does not reflect changes in the social and cultural environment and patterns of passengers. The technical basis for major decision variables is insufficient. Therefore, the theoretical basis of the area estimation formula and the pedestrian environment satisfaction of the design guideline of metropolitan railway stations were analyzed in order to suggest improvement formula. The improved area estimation formula was verified by conducting field surveys on 5 stations of metropolitan railways and 15 stations of urban railways. The existing area estimation formula is LOS E grade for the main space. However, the LOS D grade is implemented when the improved area estimation formula is applied. Based on the results, the design factors for the area estimation formula are suggested.

Simultaneous monitoring in many locations is necessary to evaluate the air quality and analyze future trend of a city, For this purpose, it is essential to install air pollution monitoring network. The first automatic air pollution monitoring network was introduced Seoul in 1973. As of 1995, 20 monitoring stations are now in operation. Concerning the management of the air pollution monitoring network, there was some argument among the relavant scholars, non-governmental organization(NGO) and the government organization. So far, there was no extensive evaluation and analysis about the network. The purpose of this study was to evaluate the representativeness of air quality monitoring network through actual measurement of the concentration of the air pollutant. The concentration of NOx was extensively measured widely in Seoul area three times using the TEA simple measuring technique. Even the judgement level for the area representativeness was lowered to 80%, Ssangmun-dong monitoring station tend to overestimate the pollutant concentration of the covered area. While, Sinlimdong monitoring station tend to underestimate the pollutant concentration of the covered area.
