Background & objectives: Understanding the awareness of policy targets and implementers about safety in the local community is the crucial to establish a systematic community safety policy. The purpose of this study was to identify the perception of local citizens and civil servants regarding community safety and its related factors. Methods: For achieving this research goal, this study conducted survey targeting 538 citizens and 404 civil servants in S-si, Kyunggi-do. Self-administred and web-based survey were used to collect data from April 1^st to 16^th 2021. Results: Civil servants scored higher in community safety perception than citizens, and S city's safety interest, information, and participation scores were also higher than those of citizens. Based on the results of multiple regression, thought about in interest of safety in S-si, providing and sharing about safety information to citizens, and participation of community safety policy were significantly associated with perception of community safety. Conclusions: Setting safety as the top priority in S city policy and paying attention to safety by the mayor, public officials, and city council members is an important way to raise citizens' awareness of local safety. Also, efforts at the city level are needed to foster safety knowledge through systematic education on safety.

This study used the contingent valuation method to determine how much consumers would be willing to pay to improve their city-gas safety and what factors influence consumers' willingness-to-pay (WTP). To elicit this information a mail questionnaire was sent to a randomly selected sample of 2,400 residents who use the city-gas. The survey results showed that individuals were willing to pay $4,750{\pm}342.8$ won per month for the city-gas safety improvement. The aggregate annual WTP was estimated at 121.5~318.0 billion won. To better understand how individual's socio/demographic characteristics affect the WTP, Censored Tobit analysis was used. The results show that higher income, more gas use (cooking and heating), willingness to install a safety instrument significantly increase consumer's WTP.

Changwon City has the second highest accident rate with 79.6 according to the city bus accident rate. In fact, 250,000 people use the city bus a day in Changwon, The number of accidents is increasing gradually. In addition, a recent fire accident occurred in the engine room of a city bus (CNG) in Changwon, which has gradually expanded the public's anxiety. In the case of business vehicles, the government conducts inspections with a short inspection cycle for the purpose of periodic safety inspections, etc., but it is not in the monitoring stage. In the case of city buses, the operation records are monitored using Digital Tacho Graph (DTG). As such, driving records, methods, etc. are continuously monitored, but inspections are conducted every six months to ascertain the safety and performance of automobiles. It is difficult to identify real-time information on automobile safety. Therefore, in this study, individual automobile management solutions are presented through machine learning techniques of inspection results based on driving records or habits by linking DTG data and Vehicle Inspection Management System (VIMS) data for city buses in Changwon from 2019 to 2020.

Purpose: Odor generated in traditional markets causes discomfort, hindering the pleasant life of residents, and complaints of odors are steadily increasing every year. Odor is defined as a smell that stimulates a person's sense of smell by stimulating hydrogen sulfide, mercaptans, amines, and other irritating gaseous substances. Research design, data and methodology: It is not easy to grasp and manage the current status of the odor analysis of living odors such as traditional markets. Seongnam City has an advanced new town of Bundang and Pangyo, while old cities such as Sujeong-gu are relatively underdeveloped. Results: As a result, the gap between the old city center and the new city center widens, so it is urgent to develop a balanced development. Based on this, the market of Seongnam-si is divided into the old city center and the new city center, and the odor complaint in the traditional market is analyzed to find a solution. A survey was conducted to understand the current status of odor management in the Seongnam-si market and the odor felt by users. Moran Market, Seongnam Jungang Market, and Kumho Market and Dolphin Market, located in the new city center, were selected as targets. The items of the survey consisted of the frequency and cause of the odor, the current status of market management, matters that need improvement, and efforts to resolve the odor. Conclusions: Therefore, this study aims to help citizens feel better about odor environment in places where odor standards are exceeded or complaints occur frequently, and to help local governments and market merchants establish more efficient and useful development plans.

Due to the rugged terrain, metro lines in mountain city across numerous wide rivers and deep valleys, resulting in instability of high-pier bridge and insecurity of metro train subjected to fluctuating crosswind. To ensure the safe operation in metro lines in mountain cities, running safety of the metro train over the high-pier bridge under crosswind is analyzed in this paper. Firstly, the dynamic model of the wind-train-bridge (WTB) system is built, in which the speed-up effect of crosswind is fully considered. On the basis of time domain analysis, the basic characteristics of the WTB system with high-pier are analyzed. Afterwards, the dynamic responses varies with train speed and wind speed are calculated, and the safety zone of metro train over a high-pier bridge subjected to fluctuating crosswind in mountain city is determined. The results indicate that, fluctuating crosswind triggers drastic vibration to the metro train and high-pier bridges, which in turn causes running instability of the train. For this reason, the corresponding safety zone for metro train running on the high-pier is proposed, and the metro traffic on the high-pier bridge should be closed as the mean wind speed of standard height reaches 9 m/s (15.6 m/s for the train).

U-City applies ubiquitous information technologies such as RFID, GPS, USN to various components of city functions and services. The concept of U-City was popularized especially in Korea and currently more than 40 projects have been carrying out all over country. U-City incorporates advanced information communication technologies into ubiquitous information services to provide better quality of life. The purpose of this study is to analyze preferences for the U-City services by surveying experts in U-City developing companies. This study employs Analytic Hierarchy Process which is very useful tool for performing multi-criteria decision making. Total of 28 responses were used in the analysis. The results indicated that the first 7 most preferred items were from transportation and safety area and environment and healthcare area and 4 out of 6 items in transportation and safety area were ranked among them. It implies that respondents consider countering anxiety caused by congested traffic, natural disasters, crimes, etc most important aspect that U-City should deal with. On the other hand, U-Port, U-Convention, U-Logistics, U-Public Administration and U-City Portal were listed as the least preferred services.
