보행은 인간의 기본적이면서 중요한 교통수단이다. 최근 보행자 사고와 관련하여 보행안전이 중요시 되고 있지만, 보행자안전에 대한 노력과 관심은 매우 미미한 실정으로 경남의 보행안전의 계획 수립과 보행사고의 감소 및 예방을 위해 사용될 보행자안전지수를 개발할 필요가 있다. 이에 본 연구는 보행자 안전에 영향을 크게 미치는 인구10만명당 5년 평균보행자사고, 인구10만명당 2009년 보행자사고, 횡단보도 신호 준수율, 무단 횡단율, 14세 이하 어린이 및 65세 이상 노인인구 2009년 보행자사고의 5개 인자를 사용하여 경상남도의 10개시를 대상으로 보행자안전지수를 개발하였다. 이 지수는 100점 만점으로 환산하며 점수가 높을수록 보행자안전이 양호함을 나타낸다. 창원시, 김해시, 마산시의 보행자안전이 양호한 반면 사천시, 통영시의 보행자안전은 열악한 것으로 분석되었다. 통영시의 보행자안전지수가 낮은 것은 높은 보행자사고율에 기인하며 사천시는 5년 평균보행자사고와 어린이 및 노인 보행자사고율이 높고 무단 횡단율이 높은데 기인함을 볼 수 있다. 경남도 10개 군의 보행자안전지수를 산정하면 함양군과 합천군의 보행자안전이 양호한 반면 함안군, 하동군, 고성군의 보행자 안전이 열악한 것으로 분석 되었다.

This study developed a Safety Culture Impact Assessment Model (SCIAM) which consists of a safety culture assessment methodology and a safety culture impact quantification methodology. The SCIAM uses safety culture impact index (SCII) to monitor the status of safety culture of the NPPs periodically and it uses relative core damage frequency (RCDF) to present the impact of safety culture on the safety of the NPPs. As a result of applying SCIAM to the reference plant (Kori 3), the standard for the healthy safety culture of the reference plant is suggested. SCIAM might contribute to improve the safety of the NPPs (Nuclear Power Plants) by monitoring the status of safety culture periodically and presenting the standard of healthy safety culture.

The purpose of the rules on the Occupational Safety and Health Standards (hereafter safety and health rules) is to regulate the safety and health measures stipulated in the Occupational Safety and Health Act and the specific instructions necessary for their implementation. However, the safety and health rules are extensive and complexly connected, making navigation difficult for users. In order for users to readily access safety and health rules, this study analyzed the frequency, distribution, and significance of terms included in the overall rules. First, the term distribution index was created based on the frequency and distribution of words extracted through text mining. The term distribution index derives from whether a word appears only in a specific chapter or across all rules. This allows users to effectively explore terms to be followed in a specific working environment and terms to be complied with in the overall working environment. Next, the related words of the previously derived terms were visualized through t-SNE and the Word2Vec algorithm. This can help prioritize the things that need to be managed first, focusing on key terms without checking the overall rules. Moreover, this study can help users explore safety and health rules by allowing them to understand the distribution of words and visualize related terms.

건물의 소방설비시스템의 유지 관리 상태에 이상이 나타났다고 한다면, 특정 기능의 이상이 미치는 부분적 또는 전체적인 화재안전대응수준에 영향을 미친다. 따라서 효율적 소방성능을 유지하기 위해 설비기능의 가동상태를 나타 낼 수 있는 성능지수의 계산 체계가 필요하다. 이러한 성능지수의 체계는 정보수신자가 부분 이상으로 발생한 영향이 전체 기능의 상태에 얼마나 영향을 주는 것인지를 쉽게 인지할 수 있도록 하는 데에 기여할 수 있다. 따라서 건물의 화재안전수준을 나타내는 효율지표로 사용될 수 있을 뿐만 아니라, 광대역규모의 소방 관리에서도 활용성 높은 지수로 사용될 수 있다. 본 지수 산정체계는 U-건물 소방방화시설관리 운용시스템의 성능 효율지수 산정을 위한 시스템으로 개발되었다.

The Korean e-Navigation system is a Korean approach to correspond with implementation of IMO e-Navigation. It provides five services, among them SV20 service, a ship remote monitoring system that collects and processes sensor information related to fire, navigation, and seakeeping performance safety. The system also detects abnormal conditions such as fires, capsizing, sinking, navigation equipment failure during navigation, and calculates the safety index and determines the emergency level. According to emergency level, it provides appropriate emergency response guidance for the onboard operator. The fire safety module is composed of three sub-modules; each module is the safety index sub-module, the emergency level determination sub-module and emergency response guidance sub-module. In this study, operational concept of the fire safety module in SV20 service is explained, and fire safety assessment factors are estimated, to calculate the fire safety index. Fire assessment factors included 'Fire detector position factor,' 'Smoke diffusion rate factor,' and 'Fire-fighting facilities factor.'

The importance of safety culture improvement and transformation has highlighted since an organization's safety culture can be the causal factor of the accident. Every designated aviation training school have to manage their own SMS and will comply with the regulations specified in article 49, Korean Aviation law. In related regulations, it is specified the safety culture status and problems of an organizations must be accessed and improved. On this study, safety culture index of designated aviation training school has measured using abbreviated CASS developed by KTSA. Results from the statistical analysis, the overall safety culture average found as 3.711. Among the subindex, mean of 'Employee Empowerment' appeared the most high(3.980) and 'Reward System' appeared the most low(3.309). Service providers are able to apply the intervention strategy on the basis of the results of these measurements. The weak part of Safety Culture might be improved and this will lead the better organizational culture.

The purpose of this study is to verify the assessment of the risk index by the AHP method effective in the bridge construction. We compared that by the AHP method with the risk index by the accident analysis in the bridge construction. This method results in the useful tool deciding the assessment of the risk index according to work type in the bridge construction.

It is necessary to deal with the process capability index carefully because it has been developed with certain assumptions. Companies make a decision on processes through the results obtained by using and treating data extracted from the processes. However if they have incorrect or wrong results, they cannot lead to proper outputs but also bring to loss of the competition in quality. Therefore, this study will show a method to analysis Cp (process capability ; CP) and an idea of mass-production on Pp (process performance ; PP) based on the Sigma Estimate which is one of the uncertainty in the process capability index and makes a lot of error. To apply this method, it is essential to understand and to analyze the processes exactly. Especially, it is required to establish the more accurate process capability index that can quickly and properly respond to changes on processes to recognize the small changes on the process which lies in specification in mass production system that the continual monitoring of quality managers is required.

The main objective of this paper is to provide analysis of obesity index of residents in six metropolitan cities. According to analysis of $R{\ddot{o}}hrer$ Index, there was significant difference regionally between men and women in metropolitan cities. Through analysis of Drop Value, it was found that there were significant differences regionally between men and women in metropolitan cities on circumferences of chest, waist and buttocks. The result of this research can be utilized in manufacturing and design of uniforms and equipments for safety.
