Traffic safety issues have recently been seriously magnified, due to child deaths in apartment complexes and parking lots. Accordingly, traffic safety technologies are being developed to recognize dangerous situations on living roads and to provide warning services. In this study, a collision detection algorithm was developed to prevent collision accidents between moving objects, by using object type and location information provided from CCTV monitoring devices. To determine the exact collision between moving objects, an object movement model was developed to predict the range of movement by considering the moving characteristics of the object, and a collision detection algorithm was developed to efficiently analyze the presence and location of the collision. The developed object movement model as well as the collision detection algorithm were simulated, in a virtual space of an actual living road to verify performance and derive supplementary matters.

Objectives We aimed to assess the radiation exposure for epidemiologic investigation in residents exposed to radiation from roads that were accidentally found to be contaminated with radioactive cesium-137 ($^{137}Cs$) in Seoul. Methods Using information regarding the frequency and duration of passing via the $^{137}Cs$ contaminated roads or residing/working near the roads from the questionnaires that were obtained from 8875 residents and the measured radiation doses reported by the Nuclear Safety and Security Commission, we calculated the total cumulative dose of radiation exposure for each person. Results Sixty-three percent of the residents who responded to the questionnaire were considered as ever-exposed and 1% of them had a total cumulative dose of more than 10 mSv. The mean (minimum, maximum) duration of radiation exposure was 4.75 years (0.08, 11.98) and the geometric mean (minimum, maximum) of the total cumulative dose was 0.049 mSv (<0.001, 35.35) in the exposed. Conclusions An individual exposure assessment was performed for an epidemiological study to estimate the health risk among residents living in the vicinity of $^{137}Cs$ contaminated roads. The average exposure dose in the exposed people was less than 5% of the current guideline.

This investigation aims to provide basic data for rural village planning and rehabilitation planning. Public infrastructures of forty selected villages have been surveyed. Provision of facilities, user satisfaction, perceived problems, and conditions of maintenance have been surveyed for three classified types of infrastructures; 1) public utility spaces such as community hall, and parking lots, 2) public production infrastructures such as warehouses, and irrigation facilities, and 3) public infrastructures for living environments such as roads, water supply, and sewage system. All twenty smaller villages (ki-cho-ma-ul) had problems of poor conditions and insufficient spaces with community halls. Most of the smaller villages suffered from lack of public production infrastructures, or had problems of insufficient spaces and poor maintenance conditions. They also lacked good access roads with adequate right of ways. Only three villages were provided with sewage systems. In the twenty larger villages (myun-bo-ma-ul), though public utility spaces were provided for most of them (as an example, sixteen villages had welfare centers), they were not large enough and they were maintained in poor condition too. On the one hand twelve of the larger villages had farm machine service centers, only a few villages were equipped with warehouses. Many more public infrastructures for living environments were found in larger villages. However, only a few villages had pollution control facilities. Multidimensional scaling revealed groups of distinctive characteristics, in terms of public infrastructures, among smaller villages. It did not show any noticeable distinctions among larger villages.

The purpose of this study is to examine the change of inner roads responding to the street system and to examine the how to influence to communal space of village focused on 22 existing old settlements in downtown Cheong Ju. This study examined the types of inner roads based on advanced research. For the research on communal space, interviews with the residents living in the village were conducted to figure out the location and function of it. Also, it was analyzed comparatively with the present communal space. The results are as followings: the width of an inner road has a effect to function of an inner road when flow of an inner road has kept. The function of inner road has been kept when the width of an inner road expanded as pedestrians should be given priority to vehicular traffic. However, the function of inner roads has been changed and the community has been separated when the width of inner roads expanded for vehicular. Because the location of the communal space in the village is affected by the change of the inner road, when the inner road is maintained, the location of the communal space is also maintained, but when the inner road is changed, the location of the communal space is also changed. The communal spaces such as public wells and wash spaces have lost and they have been substituted with senior citizen centers or community centers.

폐고속도로를 포함한 폐도 혹은 폐도로란 구 국도 중 자체 활용계획이 없고 지방자치단체에 이관하더라도 도로로 존치할 필요가 없는 구간으로 유지관리가 제대로 되지 않아 지표면 침식에 의한 지하수 오염, 야생동물 서식처의 파편화 및 생태 단절 등 여러 가지 문제를 초래하는 경우가 많다. 폐도로 복원사업은 용도폐기된 고속도로를 친환경적으로 복원하여 환경적 심미적 차원에서 긍정적인 효과를 얻고자 하는 사업으로 사업비용은 명확하게 존재하나 그 편익의 경제적 가치를 측정하기 어렵다. 본 연구에서는 비시장 재화의 편익을 측정하기 위해 광범위하게 이용되고 있는 조건부 가치측정법(contingent valuation method, CVM)을 이용하여 폐도로 복원사업의 경제적 가치를 추정하였다. 추정 결과는 우리나라 전체 가구의 약 40%가 폐도로 복원사업에 양(+)의 지불의사를 가지고 있는 것으로 나타났으며 환경이나 동 사업에 대한 인식이 높을수록 지불의사비용이 높아지는 것으로 나타나 개별 경제주체들의 환경복원에 대한 인식을 제고함으로써 폐도로 복원사업의 사회적 지불의사를 높일 수 있음을 확인할 수 있었다.

이 연구는 생활안전 교통사고 중 취약계층인 아동들에게 발생하는 아파트단지 내 교통사고를 중심으로 사고발생의 문제점과 개선방안을 제시하는 데 그 목적이 있다. 현재 아파트단지 내는 자동차, 오토바이, 전동킥보드 등의 주행이 많아지고 운전자와 보행자의 안전인식이 낮음에 따라 교통사고 발생이 빈번해지고 있다. 그러나 대부분의 아파트단지 내 도로는 도로교통법 상 '도로'에 해당되지 않는 도로 외 구역으로 처벌이나 법규가 의무화되어 있지 않음에 따라 아파트 단지 내 교통사고 위험성 인식이 매우 미흡한 실정이다. 이에 따라 본 연구에서는 아동 아파트단지 내 교통사고 사례를 파악하고 사고발생에 대한 문제점과 개선방안을 제시하고자 하였다. 아동 교통사고 사례를 통한 교통사고의 문제점 시사는 아동과 보호자 그리고 운전자들에게 위험을 인지시키고, 아파트 단지 내 교통안전 방안을 제시한다는 점에 의의가 있다.

도로는 지역경제의 성장과 지역간 연결성 그리고 생활환경의 질을 높이는데 기여하는 사회 간접자본 시설이다. 현재 우리나라는 도로와 같은 사회 간접자본 시설의 증가가 특정 지역에 편중되어 있어 지역간 큰 불균형을 이루고 있다. 또한, 일부지역에서는 지역경제 성장의 근간이 되는 도로의 부족으로 인해 대기업 및 중소기업들이 지역 내 투자를 꺼려해 지방세수입의 감소 및 지역의 산업, 경제발전과 지방재정자립도의 부실 등 지방경제재정 전반이 취약한 실정이다. 한편, 중앙집권시대에서 지방 분권화 시대로 넘어가면서 지방 사회 간접자본 시설 확충에 대해 국토의 전반적인 개발을 우선시하는 균형화 개발보다는 기존의 경제적 규모에 의한 개발정책이 우선시 되어 지역간의 경제적 격차를 고착화시키고, 나아가서는 지역적 부의 차이가 교육, 사회, 문화, 예술 등 전반적인 삶의 질까지 차등화 하려는 조짐을 보이고 있다. 본 논문에서는 국토의 균형 발전과 지방경제 활성화를 위해 필요한 조건 가운데 하나인 도로건설을 중심으로 도로성장과 지역경제에 관한 분석을 시도하였다.

Objectives: The aim of this study was to determine environmental chemical exposure related to residential and personal lifestyle characteristics in the adult Korean population. The observations of this study can provide information useful for developing reduction approaches for exposure to chemicals among the general adult population. Methods: The second stage of the Korean National Environmental Health Survey (KoNHES) was conducted from 2012 to 2014, with 6,478 persons participating. Using the results of the survey, the relationship between exposure levels of heavy metals and organic chemicals and exposure factors, e.g. residential and personal lifestyle characteristics, were analyzed. Results: The exposure levels of VOCs and PAHs were significantly lower in participants living at a distance of more than 100 m from roads versus living closer to roads. Home ventilation lowered VOC and PAH exposure but did not lower chemical exposure from household products. Use of public transportation showed lower exposure to heavy metals, VOCs, and PAHs. Current smoker was significantly higher for levels of heavy metals, VOCs, and PAHs, and the exposure trend was similar for current drinkers. Physical activity was related with higher exposure to phthalates and environmental phenols. Conclusion: Our observations based on a nationally representative population for Korea show that exposure to chemicals varies by residential and personal lifestyle, and this should be considered for developing appropriate mitigation measures and policies. Given the health concerns surrounding environmental chemicals, it is necessary to develop comprehensive measures to reduce chemical exposure.

This study aims to evaluate the residential exterior environment and ascertain the factors having an effect on the visual environment viewed through the living room window. This study is based on a questionnaire on the exterior environment targeting residents living in the area of Nohyunng in Jeju city, Jeju-do. The results are as follows. First, residents are satisfied with the exterior environment as a whole; however, the longer-term residents' level of satisfaction is found to be relatively low while dissatisfaction is high. Additionally, there is a difference in satisfaction and dissatisfaction levels between the residents in their own housing and those in rental housing. The residents living in rental housing were found to have a relatively low level of satisfaction and high dissatisfaction. Second, in the case where the living room window faces roads, low satisfaction and high dissatisfaction levels with the visual environment were found, where the living room is on the first or second floor. Third, satisfaction and dissatisfaction with the exterior environment have a close correlation to the impression or nature elements of 26 questions but they show low correlation in size, height, color, design, traffic, artifact elements. Finally, as a result of extracting the factors influencing satisfaction and dissatisfaction with the visual environment, four factors were extracted including "Impression & Nature factor", "Building factor", "Design factor", and "Traffic volume & Artifacts factor". "Impression & Nature factors" is the most influencing factor with satisfaction and dissatisfaction and "Traffic volume & Artifacts factor" was found to have an effect on satisfaction, but not as clearly on dissatisfaction.

This study investigated changes in the spatial structure of rural villages in Sayang Village, where accessibility restrictions to island areas were improved, and analyzed the spatial composition of houses according to changes in the living environment. First, despite the island's vulnerable transportation requirements being resolved by the completion of the land and bridge in 2018, the local economy continues to stagnate due to a vicious cycle of local living services and job losses. Second, when a survey of residents' changed living services was conducted through the continuation of the specification map, the scope of living areas was expanded by analyzing the frequency and place of visit of fresh food purchases, use of convenience facilities, and medical visits. Third, it is judged that the naturally formed village is composed of small roads to the inside of the village due to the disorganized street system and the form of walking instead of vehicles. Finally, as a result of analyzing the residential space of houses in fishing villages, the aging rate of houses over 30 years old was 62 (91.2%), and the average area of the first house space built was 65.2m² to 14.1m², an increase of 17.8% of the total area.
