This research is the study on the comparative evaluation of SPC (Staggered Pedestrian Crossings) vs PC (Pedestrian Crossings) using risk analysis. Accident factor was elicited by survey of driver's and pedestrian's at SPC & PC. I estimated the weight of a risk of violation and a mental burden by AHP (Analytic Hierarchy Process) and compared degree of risk at SPC AND PC. In conclusion, a new alternative plan of a pedestrian crossing system, staggered pedestrian crossing which plays an important role in traffic flow, pedestrian's crossings which plats an important role in traffic flow, pedestrian's convenience and traffic safer is sager than pedestrian crossings the degree of risk used this study doesn't imply an measure of the number of accident and the rate of accident, in estimating the degree of risk of pedestrian crossings, we should analyze more data of accident, behaviors, and road circumstance to include driver's and pedestrian's violation behavior in an estimate index.

This frame analysis attempts to shed light on the process by which the Korean press constructs crisis as social reality through a series of risk reporting on food safety. Based on the FSSI(Food Safety Sentiment Index) developed by KIHASA(Korea Institute for Health and Social Affairs), 11 cases of food safety reports from 1989 to 2005 were collected from the Korean Integrated News Database System(KINDS) and analyzed to yield the following salient features: risk diffusion frame; attribution of responsibility frame; conflict frame. It was observed that the press exhibited a tendency to approach the food safety incidents from a bi-polarized perspective, amplifying dichotomy between the victim and the perpetrator rather than treating them as scientific, or environmental hazards that require precise and synthesized information for resolution. This occupational habit of attributing status to agents of news was also found to contribute towards construction of crisis as social reality.

This study analyzed the contents of articles on GMO in Chosun Ilbo and Hankyoreh from 1994 through 2015 to check the trend of reporting on GMO as a science and technology risk issue. As a result, 'risk' and 'anxiety/concern' were continuously treated as important subjects, and there was a lack of depth and journalist's professionalism in all three periods: 'Introduction of GMO technology (1994-2000)', 'Development of GMO technology (2001-2010)' and 'Social acceptance of GMO (2011-2015).' In a comparison between the media with different ideological goals, the Chosun Ilbo had a stronger new-technological inclination to GMO than the Hankyoreh in reporting topics and tones of arguments. As a result of checking the relation of the tones in reporting with the 'risk-benefit' of GMO, reports in negative tones underlined 'risk' while those in positive tones, 'benefit.' This study could suggest improvements of subject bias and unprofessionalism in the domestic science journalism, the barometer of public awareness of disputes over science and technology risk.

방사성폐기물 관리시설에 관한 신문의 관심은 매우 컸으며, 3개월 동안에 480건의 기사를 8개 신문에서 실었다. 사설도 38건이었으나 상황과 사안에 따라 모든 신문이 정형화된 내용과 비판을 하였다. 기사는 대부분 정부의 보도 자료에 의존한 하거나, 시위소식 등을 전하는 단순사안이었고, 심층보도는 이 사업 추진에 가장 큰 장애요소가 되고 있는 지역주민과 시민단체의 반대논리와 여론을 이해할 수 있도록 전달하지 못하였다. 특히 가장 쟁점이 될 수 있는 방사성폐기물의 위험과 안전에 대해서는 68건의 심층 보도 가운데 17건에서만 언급되고 있었는데, 그 내용도 위험성과 안전에 대한 해설이나 분석기사는 아니었다. 결과적으로 신문은 정부와 지역주민간의 갈등을 해결하는 조화의 장을 이끌어 내거나 제공하지 못하였고, 찬성과 반대 측 전문가들에게 공론의 장을 제공하여 사회적 합의를 도출하는데 기여하지는 못하였다. 오히려 많은 기사 보도의 남발로 방사성폐기물 관리시설에 대한 부정적인 이미지를 부각시키는 영향만 남았다고 판단된다.

Product harm crises can distort long standing favorable equality perceptions, tarnish a company's reputation, cause major revenue and market-share losses, lead to costly product recalls, and devastate a carefully nurtured brand equity. However, in spite of the devastating impact of product-harm crises, little systematic research exists to asses its marketing consequences. So, this study focuses on the negative publicity about companies and their products. Namely, this study presented how inclusion effect supported the relationship between negative publicity and consumers' response, market performance. According to the results, after negativity publicity was happened, it was appeared that the negativity image spread into other product lines(spillover effect; inclusion effect). Also, when they contact with the negative publicity, respondents negatively evaluated both production evaluation and corporate evaluation. And, in that case of the products with negativity publicity, compared with refutation strategy(defense strategy<study 2>), improving strategy(correction notice) had positive influence on recovery of sales, product evaluation, and corporate evaluation. Finally, as the reaction time toward negativity publicity was faster, the market performance got worse. Especially, according to two-way interaction, when the reaction time was fast, the difference between refutation strategy(defense strategy<study 2>) and improving strategy was not existed in product evaluation and corporate evaluation. However, when the reaction time was late(after a month), improving strategy had more positive evaluation than defense strategy in product evaluation, and corporate evaluation.

Detection of crosswalk is an important issue for the blind to walk without the help of others. There is a braille block on the sidewalk, which helps the blind to walk. On the other hand, crosswalk is more dangerous due to the moving vehicles. However, there is no appropriate means to induce the blind. In this paper, we propose a method to detect crosswalk in front of a blind and estimate its direction using an image sensor. We adopt multi-ROIs and make their binary versions. In order to determine whether it is a crosswalk, two features are extracted; one is the number of crossing in the binary image and the other is the ratio of white area. We can also estimate the direction of the crosswalk through the slope of the projection data. We evaluated the performance using experimental dataset and the proposed algorithm showed 80% accuracy of detection.

Seoul metropolitan government has introduced Bus Rapid Transit (BRT) systems in some major urban corridors on July 1st, 2004, and has reported that it was successful on the ground that bus speed has been increased in the corridors with BRT system and that it has also resulted in the increase of bus patrons. However, there comes a negative claim that BRT has increased the number of fatalities in the same corridors. This study first aims at developing safety evaluation indicators of pedestrian crossings, then compares values of those indicators from pedestrian crossings with and without BRT systems. The safety evaluation indicators of pedestrian crossing are developed as: the number (or ratio) of conflicts between pedestrians and vehicles, the number (or ratio) of vehicles violating pedestrian signals, the number (or ratio) of pedestrians remaining crossings at red signals, and the number (ratio) of pedestrians walking beyond crossing areas. When we compare values of these indicators for both pedestrian crossings with and without BRT system, it has turned out that crossings with BRT systems has more number of conflicts than the crossings without BRT systems, but it cannot be said that the ratio of conflicts will be different between two crossing types. It means that the number of conflict will increase as the number of pedestrians and vehicles in the crossings. When we note that BRT system intrinsically attract more number of pedestrians who get-in or get-off bus stops, we cannot said that BRT system will be safer for pedestrians.

This study presents risk ranking by accident types at intersections, crosswalk and tunnel sections. An ordered logit model was used to estimate the accident severity of traffic accidents based on 58,868 accident records that have occurred on the Seoul and Gyeonggi-do over the period 2014-2017. The factors affecting the injury severity were identified by the estimated model first, and risk ranking was proposed according to conditions of accident occurrence using relative ratio analysis later. The analysis results showed that the injury severity dramatically depends on the location and time of the accident. The analysis results showed that the injury severity dramatically depends on the location and time of the accident. Furthermore, there are severe injury cases in terms of the injury severity despite the small number of occurrence of traffic accident, or there are severe injury cases in terms of the injury severity despite the high frequency of occurrence of traffic accident.

최근들어 각종 언론들을 통해 닷컴 위기론이 강하게 제기되고 있다. 그와 맞추어 모든 언론의 보도양상도 위기론을 말하지 않으면 안된다는 의무감까지 생기는 모양이다. 이와 관련해 최근의 언론매체의 보도양상을 살펴보면 크게 두가지로 나누어 볼수 있다. 첫째, 전문가의 입을 빌리는 것이 하나의 방법이고 다음으로 업계에서 떠도는 소문을 짜 맞추어 하나의 시나리오를 만드는 것이다. 물론 양자 모두 픽션을 그리고 있지는 않다. 그러나 가장 위험한 것은 일부 여론의 태도인데 미 보도된 기사에 덧붙여 닷컴위기라는 동어반복을 한다는 것이다. 즉 동어반복 이외에는 아무런 실체가 없다는 것 때문에 경제에 매우 부정적인 영향만 끼친다는 것이다.

일반적으로 교차로에서의 보행자 사고는 대부분이 횡단보도에서나 횡단보도 주변에서 발생하는 것이 많다. 이것은 운전자의 안전의식부족뿐만 아니라 보행자들이 교통법규를 지키지 않기 때문이다. 교통사고는 운전자나 보행자를 막론하고 안전의식 수준 및 안전시설의 질적 수준과 밀접한 관련이 있다. 특히 횡단보도 위치와 관련한 정지선에 대한 기준이 없어서 횡단보도 전후에 정지선이 2개가 설치된 곳이 많아 차량간의 사고를 유발하고, 보행자는 보행동선을 단축하기 위해 횡단보도 주변횡단이라는 위험한 행태를 유발하지만 이에 대한 연구나 대안제시가 이루어지지 않고 있다. 본 연구는 요인분석법이란 다변량 통계기법을 통해서 사고기록과 형태자료를 분석하였다. 사고기록은 정지선이 2개에서 1개로 변경된 25개 교차로에 대한 보행자와 차량의 유형별, 위치별, 피해정도별 사고기록을 조사 분석하고 행태분석은 현재 정지선이 2개인 곳과 기하구조가 유사한 정지선 1개인 곳을 하나의 쌍으로 해서 모두 8쌍(16개의 교차로 횡단보도)를 조사 분석하였으며, 마지막으로 설문조사를 통해서 보행자의 교통법규 준수와 인식정도에 대한 조사를 통해 보행자들의 인식과 행태조사를 통한 교통법규 준수 정도를 알아보았다. 사고자료의 분석을 통해서 첫째, 정지선이 2개인 교차로는 교차로내 차량사고, 접근부의 후면 추돌사고, 횡단보도에서 보행자사고가, 둘째, 정지선이 1개인 교차로는 유출부 차량사고가 많은 것으로 나타났으며, 행태자료의 분석을 통해서는 첫째, 정지선이 2개인 곳은 횡단보도를 이탈 또는 진입하면서 횡단하는 보행자, 점멸신호에 횡단 시작하는 보행자의 행태와 보행자 신호에 횡단보도를 통과하는 차량, 둘째, 정지선이 1개일 때는 횡단보도를 침범해서 정지하는 차량, 도로에 내려서서 기다리는 보행자가 많은 것으로 나타났다. 마지막으로 설문조사와 행태조사를 종합하면, 보행자들의 인식으로는 약 71%의 응답자와 점멸신호의 의미를 알고, 전체 응답자의 약 58%가 점멸신호에 건너지 않고 기다린다는 응답(교통법규준수)을 했으며, 실제 행태에서는 약 12.4%가 위반하는 것(87.6% 법규준수)으로 나타났다. 보행자들이 응답한 것보다 실제 행태에서는 더 많은 보행자가 교통법규를 준수하는 것으로 나타났으며, 횡단보도를 이용하는데 있어서 횡단보도를 침범하는 차량과 신호시간이 적다는 의견이 많았다.
