This study examined the life safety factor of residents living in a university village. The results of the study were as follows. First, previous research results and social safety-related research and practical system for a wide range of exterior space, including the driveway of the living space was a relative lack. Based on the survey results, the psychological factors that affect the life safety environment of the living space was found in the exterior space environment. Second, the living safety factors in the exterior space of a one-room residence can be shown by four types, such as occupant monitoring, residential surveillance and area classification, external public space utilization, and pleasant environment maintenance in the architectural planning dimension. Third, the results of research on the exterior space of the university one-room village, and life safety environment of exterior space, such as design of pedestrian street, revealed a very poor resident population and one-room buildings in most areas.

파괴안전설계를 하기 위하여 파괴역학원칙을 성공적으로 적용시키기 위해서는 주로 믿을 수 있는 크랙성장을 예측하는데 달려있다. 일정크기의 피로하중을 받는 구조물 구성요소의 경우 안전계수로 빈도수와 환경의 영향을 설명할 수 있다면 경험적인 데이터를 바탕으로 하여 그 피로거동은 상당히 쉽게 예상될 수 있다. 그러나 구조물 구성요소가 변화크기의 피로하중을 받는다면, 크랙성장예측을 위한 데이터를 마련하는데는 무엇보다도 그러한 변화크기의 피로하 중상태의 적용모델이 확실히 필요하며, 일어날 수 있는 여러 가지 상황들을 통합할 수 있는 모 델에 입각하여야 한다.

The major purpose of this paper to identify safety climate practices, and to find the affecting variables that influence to the difference in the level of safety climate between plants and employees. And this paper attempted to find the interventions for improving safety climate in the chemical plants. The questionnaires were developed from literature review, especially made by HSE(Health and Safety Executive) in the UK and distributed to managers and workers. The frequency analysis was applied for identifying the level of safety climate. The affecting variables(plant size, accident occurrence, accident experience, injury experience and severity, and length of employment) are tested through analysis of variance(ANOVA). The results of frequency analysis showed that both managers and workers recorded generally high level of safety climate, and the major underlying problems are inadequate H&S procedures/rules, pressure for production, and rule breaking. According to the outcomes of ANOVA, the variable 'length of employment' is the only variable which makes the level of safety climate different. From the survey of safety climate practice, this study finds the level of safety climate and three major underlying problems in safety climate factors of the responded plants, and presents two interventions for improving safety performance. Despite of these outcomes, the applied factors are remained questionable for reflecting as the best ones for identifying safety climate in the chemical industry. In addition, the bias caused by self-report exist in the reliability of the response, and the equivalent size of respondents.

The representative risk evaluation techniques of the marine traffic environment are the FSA, PAWSA, & IWRAP. For the development of these techniques, the risk factors suitable to the marine traffic environment should be selected & the assessment criterion of the risk factors should be provided. The risk factors were selected as the factors that relate both to the frequency of casualty & to the consequence of casualty because the risk was defined as the frequency of casualty times the consequence of that casualty on the existing techniques. But, the risk factors relate to the consequence of casualty are excluded because the risk is defined as the sum of the risk factors including the frequency and the consequence by factors on this study. The 20 kinds of risk factors to compose the risk are selected and classified into 5 categories according to similar nature through the analysis of preceding study on the classification of the risk factors. Finally, as the foundation of risk assessment model's development for domestic marine traffic environment, the practical assessment criterion of the risk factors are suggested.

This purpose of this study is to identify the Analysis of Safety Control Factor Influenced on the Management of the Costal Shipping Companies. The study selected the analysis of safety control factors performed the Brain-Storming method, Depth Interview and Face-to-Face Interview. This survey targets are 25 experts for the opinions of expert groups with CEO of coastal shipping companies. This study used ISM(Interpretive Structural Modeling)to analyze the safety control factors and understand correlations between factors and found that sufficient acquirement of legal shipping equipment and freight (or passenger) management factors are the safety control factors that give the biggest effect on the management of coastal shipping companies. ISM analysis results are as follows. The factors that most influence the advancement of safety management is ensured the legal faithful to ship equipment. In the future, a survey have to multiple targets and to improve the practical needs by using a FSM (Structural Fuzzy Modelling).

가로수는 공원과 더불어 도시지역의 중요 녹지공간으로 도시 이미지를 높이는데 매우 긍정적인 평가요소이며 녹지연결 및 쾌적한 가로공간 창출로 그 가치를 높이고 있다. 또한 가로등은 야간 운전자와 보행자의 안전을 보장하기 위해 중요한 시설물이다. 본 연구는 야간 운전자와 보행자의 안전을 평가하기 위한 조명 시뮬레이션 기법을 이용하여 가로수의 유형과 성장이 조명환경에 미치는 영향을 분석하기 위한 접근법을 제시한다. 가로수와 가로등은 도로 설계에 있어 중요한 요소이지만 상호간에는 각 목적에 배치되는 특징들이 있다. 특히 가로수는 가로등과 같이 고정 시설물의 성격도 있지만 성장과 형태가 다양하다는 특징이 있다. 본 연구는 상호 목적을 최적화할 수 있는 방법을 제시하기 위한 출발점으로 조명 시뮬레이션 기법을 이용하여 가로수의 유형과 성장이 야간 도로 조명에 미치는 영향을 평가하기 위한 방법을 제시한다.

The purpose of this study is to analyze the level and influence factors of social safety perception of middle-aged and older adults with disabilities. The subjects of the survey were older than 50 with disabilities who responded to the 2018 Social Survey. The results analyzed by Hierarchical regression analyzes showed that factors such as gender, age, place of residence, education level, subjective health status, risk response level, compliance level of others, and compliance with public order had a significant effect on the social safety perception level. Through this study, we could know the importance of personal requirements and social capital for social safety perception of middle-aged and older people with disabilities. In the future, the differences in safety perception by type of disability should be studied too.

원자로용기의 안전성은 가동중 운전조건과 조사취화등으로 인한 재료의 열화(degradation)를 검토함으로써 평가되는데, 특히 운전조건중, 비상사태에 해당하는 가압열충격에 관한 평가가 최근 중요한 안전문제로 부각되고 있다 본 연구의 목적은 가압열충격 사고중 소규모 냉각재 손실사고(Small LOCA)가 발생하는 경우, 원자로용기 내벽에 존재하는 균열의 안전성을 유한요소해석을 통해 평가하는 것이다. 본 연구에서는 Small LOCA 발생시 원자로용기의 내벽에 존재하는 균열의 종류, 방향, 균열형상비 및 클래드부의 두께가 응력확대 계수 계산에 미치는 영향을 평가하였으며, 이를 위해 총 14가지 경우에 대해서 3차원 유한요소해석을 수행하였다. 이러한 Small LOCA 해석수행을 기초로 다양한 가압열충격 사고에 대한 유한요소해석 모델링 기법, 해석 기법, 후처리 기법을 제시하였다.
