It is necessary to hold the school safety manual because recently, the safety-related accidents occur frequently in schools. Accidents can occur inside of schools as well as out of schools, and they can be classified with human accidents, traffic accidents, fire accidents, and explosion accidents. Safety-related accidents occurring in the school are dangerous because nobody can predict them. Illegally infringing violence, targeting unspecified and a lot of people, informs the parents and persons concerned to education of danger. School safety manual, never precedented before, describes epoch-making educational methods for students' safety. It describes safety security such as refuging ways at an emergency, the way to recognize danger for elevated safety based on prevention education, the use and practice of checklist for related facilities, and the implements and facilities for school personnels and students. So, the school safety manual is an important guidance for safety education at the level of prevention from various accidents which occur inside the school as well as out of the school. It presents a variety of prompt response after an accident. At the same time, it checks facilities and dangerous factors in schools and facilities for safety, and analyzes special factors based on them. So it will present the status of safety management of existing facilities and implements, the installment of new facilities and implements, and the way to secure safety for use.

Currently the IoT (Internet of Things) environments and related technologies are being developed rapidly through the networks for connecting many intelligent objects. The IoT is providing artificial intelligent services combined with context recognition based knowledge and communication methods between human and objects and objects to objects. With the help of IoT technology, many research works are being developed using the C-ITS (Cooperative Intelligent Transport System) which uses road infrastructure and traveling vehicles as traffic control infrastructures and resources for improving and increasing driver's convenience and safety through two way communication such as bus-only lane and license plate recognition and road accidents, works ahead reports, which are eventually for advancing traffic effectiveness. In this paper, a system for deciding whether the traveling vehicle is possible or not to drive on bus-only lane in highway is researched using the lane and number plate recognition on the road in C-ITS traffic infrastructure environments. The number plates of vehicles on the straight ahead and sides are identified after the location of bus-only lane is discovered through the lane recognition method. Research results and experimental outcomes are presented which are supposed to be used by traffic management infrastructure and controlling system in future.

지난 10여 년 동안 대만사회의 가장 큰 변화 중 하나는 '개인 경비', 혹은 '개인 경호' 사업이 크게 발달했다는 것이다. 민간의 역량과 과학화된 설비로써 재산보호와 신변보호를 하고자 하는 개인 경비에는 여러 방식이 있다. 예를 들어 개인안전 경비(즉, 수행경호), 현금운송 경비, 주거경비, 상공업경비(여기에는 공장지대의 안전한 보호와 백화점, 금융기관, 보석상점 및 편의점 등의 경비가 포함됨), 그리고 각종 경비장치의 설치 등이 있다. 천징훼이(陳靜慧, 2006)는 대만의 경비 산업 경영형태에 대해 아래와 같이 분석하였다. 그의 주장에 따르면, 대만의 경비 산업은 일반 업무 위주로 하고 있으며, 여기에는 시스템 경비, 상근 경비, 현금 경비, 신변 경비가 있다고 밝혔다. 이 일반 업무는 일본, 미국, 독일의 형태와 유사하다. 그러나 미국과 독일의 경비회사들은 특수한 업무를 담당하고 있다. 미국의 경우 무장경비 현금수송, 신용조사 업무, 보험조사 업무, 거짓말 탐지 업무를 수행한다. 독일의 특수 업무에는 군대설비 경비, 교통지휘 및 질서 유지, 신속 고발 경비, 그리고 교도소 경비가 있다. 량신쩐(梁心禎, 2006)은 대만의 경비 산업 발전의 흐름에 대해 다음 세 단계로 구분했다. 제1단계는 1978년부터 1987년까지로 이 시기 대만은 일본 경비 사업 발전의 영향을 수용했기 때문에 일본의 경비사업 관리방식과 시스템 설비를 받아들여 점차 대만 방식의 경비 형태로 발전시켜 나갔다. 초기 발전단계의 경영방식은 주로 외국 기술과의 협력을 통한 시스템 경비가 주를 이루었다. 제2단계는 1988년부터 1997년까지인데, 이 시기에 이르러 경비 사업은 비인기 사업에서 인기 사업으로 시장이 확대되었고, 해외업체와의 활발한 기술 교류, 새로운 브랜드 개발과 경비 경영 방식의 혁신, 그리고 상근 경비와 수행경호와 같은 경비 관련 항목의 확장을 이루었다. 또한 이 시기에 수많은 경비회사들이 세워져 새로운 경쟁시대로 돌입하였다. 제3단계는 1998년부터 현재까지로 이전의 전통적인 건물경비 방식에서 경비와 부동산 관리 서비스를 함께하는 방식으로 경영 형태가 바뀌었고 전반적인 서비스 품질을 중시하기 시작하였다. 따라서 경비 사업자는 아파트 및 빌딩관리 보호 회사를 설립하여 이를 공동 경영하였으며, 전문적이고 종합적인 단계로 들어섰다. 대만 경비 교육제도의 설립과 제도화된 면허증 시스템 구축은 아직 초보적인 단계로써 여전히 이 두 방면의 발전을 강화시켜야 하는데, 교육과 심사를 시행하여 경비원의 소질을 향상시켜야 할 것이다. 경비사업자는 과학기술적인 통제 시스템을 받아들여 인건비를 낮추고 서비스의 범위와 품질을 향상시켜야 한다. 또한 각 지방의 노동조합은 정부가 법령을 개정하여 경비원의 자격제한과 업무를 보장해주도록 건의해야만 경호원의 대우와 이미지가 개선될 수 있다. 아울러 국제학술교류의 확대와 경비 관련 산업에 대한 토론회와 전시회를 자주 개최하여 새로운 지식을 습득해야 한다.

The Korea Maritime Safety Tribunal is an institution that investigates marine accidents in accordance with the maritime safety adjudication procedure when marine accidents occur. It requires its investigators to be capable in specializing in marine accidents, including possessing the following: a level 2 or higher maritime license, experience on boarding, and specialized knowledge on ships. It also requires separate training for technical competency related to maritime accident investigations. However, the current education for marine accident investigators mainly consists of administrative tasks, which is not suitable to improving the investigator's technological competency, making its development urgent. This study aims to design training contents for marine accident investigators to strengthen their technical competence. To this end, we analyzed the contents of current investigator training, and reviewed the relevant laws and regulations, and training contents of investigators in advanced maritime countries and similar transportation institutions in Korea. According to the results, the training contents were designed to focus on strengthening technical competency, and proposed as a five-day course for basic and professional training. Based on the designed training contents, if in-depth research is conducted by sufficiently reflecting the working conditions of marine accident investigators in Korea, it will greatly help in improving the investigators' skills.

Research related to hydrogen technology is being actively conducted around the world. Korea is also making great efforts to develop technology to leap forward as a hydrogen economy powerhouse. In particular, the world's No. 1 hydrogen vehicle penetration rate is proof of this. However, the construction of hydrogen refueling stations is being delayed. The biggest delay factor is the public opposition. As such, policies without public support cannot be successfully implemented and are not sustainable. Therefore, this study intends to analyze the factors affecting the acceptability of hydrogen refueling stations in favor of and against them. As a research method, the basic factors affecting acceptability were identified by reviewing previous studies, and a questionnaire was designed and investigated based on the established factors. The validity and reliability of the questionnaire were verified, and the hypothesis was verified through correlation analysis. And, using structural equation modeling, a factor model was developed on the acceptability of hydrogen refueling stations. As a result of the study, acceptability defined private acceptability and public acceptability. In the case of private acceptability, it was confirmed that the higher the attitude toward the environment, the higher the level of knowledge about the hydrogen charging station, and the lower the degree of feeling the risk of the hydrogen charging station, the higher the acceptability. In the case of public acceptability, it was confirmed that the higher the benefit, the better the attitude toward the environment, and the lower the risk-taking characteristics of the individual, the higher the acceptability. Therefore, in this study, based on the potential factors verified in previous studies, the main factors affecting the acceptance on hydrogen refueling stations were identified. And the acceptance model was developed using structural equation modeling. This study is expected to provide basic data to seek ways to improve the acceptance of public when implementing national policies such as hydrogen refueling stations, and to be used analysis data for scientific communication.

A survey of risk perception in Korea was conducted in 2001 with a special emphasis on industrial and technological risks. This article summarizes the characteristics of risk perception in consideration of socio-demographic background of respondents. The survey with sample size of 1,870 evaluates the perceived level of 25 risk items in the areas of transportation, chemicals, environment, industry, and nuclear power generation. Risks are categorized by using factor analysis to clarify attitudinal or behavioral properties of risk perception. Research findings show that the level of perceived risk does not correspond to the statistical level. Socio-demographic variables are significant predictors in explaining risk perception, or the discrepancies between "subjective" and "objective" risks. Effective risk communication can reduce the perceptional discrepancies, improve the awareness of technological risks, and ultimately facilitate the process of making and implementing policies for risk management and safety regulation. This article tries to provides policy guidelines for "Who is the target for risk communication" and "Which risk has the policy priority for safety improvement." Married females at the age of 30s and 40s with lower education and lower income in small cities are more vulnerable to risk misperception than other groups. More information and knowledge regarding unfamiliar, intangible, new technological risks should be delivered to the vulnerable groups for reducing perceptional bias. Society-wide safety can be improved by integrating policy, human, and social factors as well as techno-engineering advances.

An ICS(industrial control system) is a complex system that safely and efficiently monitors and controls industrial processes such as electric power, water treatment, transportation, automation plants and chemical plants. Because successful cyber attacks targeting ICS can lead to casualties or serious economic losses, it becomes a prime target of hacker groups sponsored by national state. Cyber campaigns such as Stuxnet, Industroyer and TRITON are real examples of successful ICS attacks, and were developed based on the deep knowledge of the target ICS. Therefore, for incident investigation of ICSs, inspectors also need knowledge of control processes and accident investigation techniques specialized for ICSs. Because there is no applicable technology, it is especially necessary to develop techniques and tools for embedded controllers located at cyber and physical boundaries. As the first step in this research, we reviewed logging capability of 4 PLC(Programmable Logic Controller)s widely used in an ICS area, and checked whether selected PLCs generate logs that can be used for digital investigation in the proposed cyber attack scenario.

Purpose: The recent increased use of Personal Mobility (PM) has been accompanied by a rise in the annual number of accidents. Accordingly, the safety requirements for PM use are being strengthened, but the laws/systems, infrastructure, and management systems remain insufficient for fostering a safe environment. Therefore, this study comprehensively searches the main problems and improvement methods through a review of previous studies that are related to PM. Then the priorities according to the importance of the improvement methods are presented through the Delphi survey. Method: The research method is mainly composed of a literature study and an expert survey (Delphi survey). Prior research and improvement cases (local governments, government departments, companies, etc.) are reviewed to derive problems and improvements, and a problem/improvement classification table is created based on keywords. Based on the classification contents, an expert survey is conducted to derive a priority improvement plan. Result: The PM-related problems were in 'non-compliance with traffic laws, lack of knowledge, inexperienced operation, and lack of safety awareness' in relation to human factors, and 'device characteristics, road-drivable space, road facilities, parking facilities' in relation to physical factors. 'Management/supervision, product management, user management, education/training' as administrative factors and legal factors are divided into 'absence/sufficiency of law, confusion/duplication, reduced effectiveness'. Improvement tasks related to this include 'PM education/public relations, parking/return, road improvement, PM registration/management, insurance, safety standards, traffic standards, PM device safety, PM supplementary facilities, enforcement/management, dedicated organization, service providers, management system, and related laws/institutional improvement', and 42 detailed tasks are derived for these 14 core tasks. The results for the importance evaluation of detailed tasks show that the tasks with a high overall average for the evaluation items of cost, time, effect, urgency, and feasibility were 'strengthening crackdown/instruction activities, education publicity/campaign, truancy PM management, and clarification of traffic rules'. Conclusion: The PM market is experiencing gradual growth based on shared services and a safe environment for PM use must be ensured along with industrial revitalization. In this respect, this study seeks out the major problems and improvement plans related to PM from a comprehensive point of view and prioritizes the necessary improvement measures. Therefore, it can serve as a basis of data for future policy establishment. In the future, in-depth data supplementation will be required for each key improvement area for practical policy application.

Increase of automobiles become today's environmental problem decreasing space for our children's playground. The traffic situation around us shows automobiles over filled the public roads and started to intrude even on the side walks. Children's traffic safety education for the awareness of the danger from traffic mishaps, and for the behavior to cope with preventives measure by continual learning programs in systematized method is very important need in current health education. For this research, the subject was represented by 243 students from 4th grade in D Elementary School located at Daechi-dong, Seoul. During total of 5 weeks (September 4, 1997 to September 30, 1997), lessons were taught to the subject. Lessons consist of traffic safety education and customized education program that were designed and developed specificially for the subject level. In this research, Case group of 3 classes and control group of 3classes were predetermined before subject's degree of knowledge, attitude, and practice was analized. The difference before and after the training of this education was observed to verify the effectively and to find the influential factors of this education program. On September 2-3, survey study was performed after the training. the results of this study were as follows: 1. The knowledge analysis from the comparison between before and after of the training shows case group and control group scored(8.36, 8.86) before the traning, but scored(10.36, 8.52) after the traning. the difference from the result of the case group is statistically significant(p〈0.001). 2. The attitude analysis from the comparison between before and after of the training shows case group and control group scored(48.23, 49.87) before the training, but scored (51.05, 48.45) after the traning. the difference from the result of the case group is statistically significant(p〈0.001) 3. The practice analysis from the comparison between before and after of the training shows case group and control group scored (27.42, 28.08) before the training, but scored(30.49, 28.25) after the training. The differece from the result of the case group is statistically significant (p〈0.001). 4. The correlation analysis of traffic safety education's influence on traffic safety knowledge, attitude, and practice before training shows the relationship between attitude and practice was satistically significant(p〈0.05). The result after the training shows the relationship between knowledge and attitude, attitude and practice, and knowledge and practice was all statistically significant(p〈0.001).
