As of December 2016, there are 608,828 elevators in operation in Korea and 179,790 elevators in more than 15 years. 30.4% of all elevator are aging. Improved maintenance of the elevator and proactive replacement of the parts of the elevator can extend the lifetime of the elevator and ensure safety. An unclean environment reduces the lifetime of elevator parts. If you do not clean the environment and prevent preventive parts replacement, eventually shortening the lifetime of the parts connected to the failed part or causing more damage will result in greater economic loss. Also, the risk of elevator safety accidents due to failures of elevator parts will be increased accordingly. The study of optimum replacement time of elevator parts will contribute to prevention of safety accident of elevator and prolongation of lifetime of elevator through preventive replacement of elevator parts.

Today, wearable technology products are used in a wide range of consumer, healthcare, bio-medical, and industrial applications. The market for wearable technology products is expected to increase dramatically over the next several years. In addition, concerns for safety, performance and reliability of wearable products keep increasing and will be essential for widespread acceptance in the marketplace. Wearable smart devices, which are generally in contact with the human body and skin, are exposed to the risk of the electric shock, burn, and explosion. Therefore, the standardization of wearable devices in terms of human safety and reliability should be very important. Furthermore, the development of test method and test certification of the wearable products will be one of the key technology for mass production. Such standardization and certification will help consumers to choose the safest and best quality wearable devices and allow manufacturers to prove the safety and quality of their products, thereby helping them to gain a competitive technology. This paper discusses the current status of the wearable smart devices as well as the standardization and test certification applicable to wearable technology products.

In the event of continued train operation being impossible as the result of a breakdown, it will be essential to dispatch a relief train to recover the broken down train. Operation of relief train carries with the risk of collision in the process of connection with broken down train. The present study looks at the suitability of risk management procedures and associated problems in the light of case studies of relief train operation, and of national legal standards and railroad company regulations. It looks at appropriate methods of risk management and the problems that can arise. Based on the study a method is proposed of operating the relief train which is consistent with appropriate risk management. The proposed method will improve the safety of relief train operation, It is hoped that the results of the study will be reflected in relevant laws and operating company regulations, and so contribute to enhancing the overall level of railroad safety.

This paper conducted a feasibility study by applying an Internet of Things and Artificial intelligence-based management system for the elderly living alone in an aging society. The number of single-person families over the age of 50 is expected to increase, and problems such as health, safety, and loneliness may occur due to aging. Therefore, by establishing an IoT-based care system for the elderly living alone, a stable service was developed through securing a rapid response system for the elderly living alone and automatically reporting 119. The participants of the demonstration test were subjects under the jurisdiction of the "Seongnam Senior Complex," and the data collection rate between the IoT sensor and the emergency safety gateway was high. During the demonstration period, as a result of evaluating the satisfaction of the IoT-based care system for the elderly living alone, 90 points were achieved. We are currently in the COVID-19 situation. Therefore, the number of elderly living alone is continuously increasing, and the number of people who cannot benefit from care services will continue to occur. Also, even if the COVID-19 situation is over, the epidemic will happen again. So the care system is essential. The elderly care system developed in this way will provide safety management services based on artificial intelligence-based activity pattern analysis, improving the quality of in-house safety services.

KC-100 is a 4 seats, single piston engine, civil aircraft whose type certificate is applied for KAS 23 (FAR 23) for the first time in Korea. Its system safety assessment and analysis have been conducted to meet the minimum safety requirement in KAS 23 and to verify the safety of equipment, system, and installation in accordance with the requirement of ${\S}$23.1309 and the guidelines in FAA AC 23.1309-1D and SAE ARP 4761. This safety assessment begins with the FHA (Functional Hazard Assessment) at aircraft and system level in preliminary design phase, and all of the safety assessment and analysis reports including the preliminary version of SSA (System Safety Assessment) have been prepared during detail design phase. The revised version of these safety reports will be approved by Airworthiness Authority through the ground and flight test phases. In this paper, the safety assessment requirement in ${\S}$23.1309, safety assessment guideline in AC 23.1309-1D, and safety assessment and analysis methods in ARP 4761 will be explained based on the application example for KC-100 development. The experience and knowledge of this system safety assessment for civil aircraft can be applied to commuter aircraft of FAR 23 class or large transport airplane of FAR 25 class.

This study is planned to investigate the compliance of small sized enterprises of under 5 employees directed by Industrial Safety and Health Act. Occupational safety regulation can be required for employer and employee to comply because that all members of workplace should be involved to protect worker's health. When all members of workplace comply with safety regulation, effectiveness of regulation will be realized as expectation. The study subject is composed of three groups as 501 employers, 501 employees of small sized enterprises of under 5 employees and 107 safety inspectors sampled by stratified random sampling for comparison. Data for analysis is collected from each sample using interview with structured questionnaires. Compliance is measured by 5 point scale composed by 8 sub items such as general perception, understanding, clearness, necessity, relevancy, implementation, penalty, and general compliance of the regulation. Among sub items of employer's compliance, the level of perception of regulation, necessity of regulation, relevancy of penalty are differentiated among three groups. The level of all 8 items of employee's compliance also differentiated among three groups. These results show that strategies for ensuring the same level of compliance among three groups will be needed through education, training and evaluation of regulation and feedback.

본 연구는 간호 간병 통합서비스 병동에 근무하는 간호사의 직무 스트레스, 안전통제감과 환자안전관리 활동의 관련성을 파악하고, 직무 스트레스가 안전통제감과 환자안전관리 활동에 미치는 영향을 확인하기 위한 서술적 조사연구이다. 2019년 3월 11일부터 4월 17일까지 4개 종합병원의 간호 간병 통합서비스 병동에 1년 이상 근무한 간호사 137명을 연구대상으로 하였다. 연구결과 직무 스트레스는 안전통제감, 환자안전관리 활동과 유의한 부적 상관관계가 있는 것으로 나타났으며, 직무 스트레스는 안전통제감과 환자안전관리 활동에 부정적인 영향을 미치는 것으로 나타났다. 본 연구결과를 토대로 간호 간병 통합서비스 병동 간호사의 안전통제감과 환자안전관리 활동을 증진시키기 위해 직무 스트레스를 감소시키기 위한 근무환경 개선이 요구되며, 간호 간병 통합서비스 병동 간호사의 직무 스트레스 관리를 위한 다양한 프로그램 개발이 필요할 것으로 생각된다.
