농약에 관여하는 사람은 모두 홍보요원이 되어, 농민에게는 농약을 어떻게 사용해야 농약중독을 막고 안전한 농산물을 생산하며 쾌적한 자연환경을 보존할 수 있는지, 도시민에게는 농약의 독성이 어느 정도이고 농산물 및 식품잔류농약이 인체에 어느 정도 위해성이 있는지 알려줘야 할 것이다.

The survey team has conducted the on-the-site inspection of 53 bridges to which LNG gas pipelines are attached, to ascertain their level of safety, durability and any defect by adapting a method of computer data input process and precision analysis. In this way, we could estimate an effective corrective action on the defective gas pipelines found through this survey. Our survey team has analyzed carefully these 2 defective lines selectively out of 10 lines, which are considered to be most seriously weak. According to our elaborate analysis these two pipelines go over 70% of the set standard stress based on our Safety Manual Scale. We have taken corrective actions on these lines by repairing/replacing/obsolete damaged lines to ensure the distress of the bridges involved with the pipelines and could secure safety.

Unlike conventional vehicle traffic accidents, autonomous vehicles traffic accidents can be caused by various factors, including technical problems, the environment, and driver interaction. With the future advances in autonomous driving technology, new issues are expected to emerge in addition to the existing accident causes, and various scenario-based approaches are needed to respond to them. This study developed autonomous vehicle traffic accident scenarios by collecting autonomous driving accident reports, CA DMV collision reports, autonomous driving mode disengagement reports, and autonomous driving actual accident videos. The scenarios were derived based on the functional safety system failure modes of ISO 26262 and attempted to reflect the various issues of autonomous driving functions. The autonomous vehicle scenarios derived through this study are expected to play an essential role in preventing and preparing for various autonomous vehicle traffic accidents in the future and improving the safety of autonomous driving technology.

It is important to create a decent pedestrian space in order to realize a public space that can ultimately improve the quality of life based on guaranteeing people's right to move while also enhancing urban activity. The goal of this study is to develop a pedestrian path evaluation system in order to lay the foundation for data construction leading to the creation of such elegant walking space. First, a basic system was established in keeping with factors and the space, and this system was used as the basic framework of the study. The trends identified in the literature can be divided into eight categories, denoted here as: Walking safety policy, Walking focused plan, Recognition transition, Transportaion system, Activity-linked walking, Facility utilization walking, Nature and history linked walking and Content convergence walking. The macro- and micro-indices and factors mentioned in related studies were synthesized and classified, and the basis for universality and differentiation was established by integrating them. Next, according to the basic composition of the walking system, Walking potential and slope safety in the Safety category, Basic walking connectivity and Traffic linkage in the Efficiency category, Walking arrangement and Rest convenience in the Health category, and Resource connectivity and Activity abundance in the Comfortability category macro evaluation system of the eight categories were established and a corresponding measurement method was developed.

Factor analysis is estimated using housewives's intention data in Seoul province. Rice consumers considered safety, high nutritive value, shape and cultivation region as important factors in buying rice. The factors of food safety are brand and quality certification mark. The differences of two housewife groups on safety factor are caused by residence type, employment existence and residence region. The marketing strategies for rice containing food safety target housewives living in apartment, Gang Nam region. Also selling extension for target consumers housewives should be employed.

Recently, a safety control platform to monitor the safety of train operation in real time and prevent accidents and risks through control is under study. In the initial design, DDS communication method supporting distributed network is adopted for real-time processing of large amount of data according to the integration of existing distributed safety data. However, communication between server and console inside the safety control platform is applied to existing TCP socket communication. In the case of TCP socket communication, it is possible to process data for a small system of a safety control test bed by one-to-one communication. However, if the data is expanded all over the country in the future, it becomes difficult to cope with a case where communication traffic occurs due to vast amount of data. In this paper, we propose DDS communication method to support distributed network between server and console of security control platform, and demonstrate TCP socket and DDS method, and compare throughput and speed. As a result, we have found that the scalability and flexibility are improved in case of applying DDS communication to future systems.

Recently, due to the expansion of urban infrastructure using underground spaces in urban areas, many adjacent constructions and excavations have been made carried out between existing facilities, and complaints related to the stability of existing facilities due to close construction have become significant issues. In this study, it was closely reviewed for the existing metro tunnel structure in the new Dongbuk urban metro railway to determine the behavioral characteristics of tunnel structure according to adjacent tunnel construction. Also, it was analysed the evaluation of the safety zone and excavation method for metro tunnel structure. And after a detailed damage assessment, track irregularities and structural calculation by using a numerical analysis, stability of the metro tunnel structure according to nearby tunnel excavation was evaluated to be secured for safety. This study is expected to be applied as practical reference to review the evaluation of safety effects of existing tunnel structure and buildings according to adjacent construction in complex deep urban tunnelling.

사회가 점점 고도화, 다양화, 고속화 하여가는 것과 비례하여 화재에 대한 위험성도 증대하며 일단 화재가 발생하면 그 피해 역시 막대하게 커지고 있습니다. 인간의 생활수준이 의식주를 해결하기에 급급하던 수준을 벗어나면, 즉 소득수준이 높아지면 "우선 살아야 한다"는 의식에서 "어떻게 잘 살 것인가"하는 방향으로 의식의 변화가 일어난다고 합니다. 인명을 존중하고, 생활환경 도시환경 노동환경에 있어서의 안전방재에 대한 의식도 높아진다는 것입니다. 일반적으로 그 의식의 변화는 일인당 국민소득 약 만불($10.000.-)전후에서 일어난다고 합니다. 이와 같은 사회배경을 바탕으로 섬유재료에 있어서도 보다 난연 또는 내열소재를 필요로 하게 되었습니다.

현재 많은 나라에서 지하철 역사에 승강장 스크린 도어(Platform Screen Door)를 설치하여 열차진입에 따른 승강장부의 공조환경 개선 및 승객의 안전을 확보하고자 하고 있다. 한국에서도 서울 지하철 9호선을 비롯하여 각 도시에서 PSD를 지하철 승강장부에 설치하는 노력이 시도되고 있으나, 이에 대한 검증은 전무한 실정이다 한국에서의 지하철 이용 분담율은 30％정도이며, 향후 약 50％까지 이를 것으로 예상되며, 이에 따라 PSD설비는 증가할 것으로 전망된다. 따라서 PSD 설치에 대한 지하철역사 환기 및 화재시의 배연설비에 대한 연구의 필요성은 날로 논아지고 있는 실정이다.(중략)
