In this paper, we propose waste collection vehicle system with a safety device for worker safety and an autonomous driving function. The steering system is applied as MDPS (Motor Drive Power Steering) system to control the waste collection vehicle of the internal combustion engine. Safety-related errors is prevented through redundancy brake of the integrated system and the control braking system. In order to ensure safety between workers and waste collection vehicles, work guidelines and safety devices for emergency stop in case of danger are applied to vehicles. In addition, this research is conducted on improving the working efficiency through vehicle condition monitoring system and a short-range control system for field test. This research is aimed to secure stability through demonstration and contribute to the industrialization of unmanned waste collection vehicles.

The construction companies are facing potential EHS(Environment, Health & Safety) of major accidents to cause casualties or a financial loss and increasing social responsibility. So, they have to voluntarily accomplish the EHS management system rather than passively with regard to EHS regulation. In this study, the integrated EHS management system is developed based on cloud computing, and construction companies are to materialize self-regulation EHS process of construction workplace and to standardize the total EHS business process using the developed system. The proposed system also provides risk analysis, education/control and continuous improvement for EHS tasks and users can easily access the system on the web at a low price through cloud computing service. Eventually, the integrated system contributes to the managerial improvement by minimizing economic and physical loss caused by construction accidents.

재난 및 안전관리 통계는 소방방재청과 부처 간 통계중복 및 연계성 부족으로 정책수립시 어려움이 초래되고 있으며, 통계인프라가 빈약하여 과학적 재난관리를 위한 통계관리 및 개발노력이 미흡한 실정이다. 본 연구에서는 기존의 재난 및 안전관리 통계 분류체계를 통합하고 표준화하기 위한 통계체제 정립 안을 도출하고 통계지표의 개선 및 신규지표를 개발하며, 재난 및 안전관리 통계 통합 구축방안 마련에 있다. 또한 유관기관 재난 및 안전관리 통계 활용을 위한 법 제도 정비, 방재센서스 실시방안, 통계 인프라 확충방안을 마련하는데 목적이 있다. 따라서 재난 및 안전관리 통계정비를 통한 과학적 재난관리 정책수립의 환경을 조성하고 부처별, 재난 유형별 분산관리에서 통합형 통계관리로의 개선 및 공동 활용을 기대할 수 있으며, 재난유형별 국제비교가 가능한 통계기반 마련에 기여할 것으로 기대된다.

This paper provides an integrated view on human and system interaction in advanced and automated systems, which adopting computerized multi-functional artifacts and complicated organizations, such as nuclear power plants, chemical plants, steel and semi-conduct manufacturing system. As current systems have advanced with various automated equipments but human operators from various organizations are involved in the systems, system safety still remains uncertain. Especially, a human operator plays an important role at the time of critical conditions that can lead to catastrophic accidents. The knowledge on human error helps a risk manager as well as a designer to create and control a more credible system. Several human error theories were reviewed and adopted for forming the integrated perspective: gulf of execution and evaluation; risk homeostasis; the ironies of automation; trust in automation; design affordance; distributed cognition; situation awareness; and plan delegation theory. The integrated perspective embraces human error theories within three levels of human-system interactions such as affordance level, psychological logic level and trust level. This paper argued that risk management process should dealt with human errors by providing (1) reasoning improvement; (2) support to situation awareness of operators; and (3) continuous monitoring on harmonization of human system interaction. This approach may help people to understand risk of human-system interaction failure characteristics and their countermeasures.

정부는 대구 지하철 대형 화재 사건을 계기로 2004년 철도안전법 제정과 동시에 철도안전 종합계획 추진을 통해 철도안전관리를 도모해 왔다. 그러나 여전히 열차 충돌, 탈선 및 화재 등 대형 인명피해로 이어질 수 있는 열차사고가 지속적으로 발생하고 있음에도 불구하고, 사후 처리 중심의 안전관리시스템이 운영되고 있는 실정이다. 따라서 본 연구에서는 기존의 분산되어 운영되고 있는 안전검지 장치 데이터를 통합하여 선제적 안전 관리를 위한 실시간 철도 안전 감시제어 시스템 개발에 대한 기본 프레임워크를 제안하고자 한다. 또한 철도 안전 감시제어 시스템의 효과적인 작동 여부를 모니터링하기 위한 안전성과모니터링지표에 대한 개발 방향을 제시하고자 한다. 제안된 프레임워크는 향후 추진될 실시간 철도 안전감시 제어시스템의 구현을 위한 기틀을 마련할 수 있을 것으로 전망된다.

In recent years, the many electric saving methods are studied because of difficulty of meeting the demand. The electric energy management such as monitoring of branch power consumption, demand control, metering, power quality monitoring, electric safety monitoring can make energy saving. The purpose of this paper is to develop a system which can provide the integrated management of various functions required for energy management by consumers. In this system all functions which were embodied into each devices are integrated into intelligent meter. The developed systems are tested and implemented by installing at consumer electric distribution panel.

EPC seeks to minimize variability by transferring the output variable to a related process input(controllable) variable, while SPC seeks to reduce variability by detecting and eliminating assignable causes of variation. In the case of product control, a very reasonable objective is to try to minimize the variance of the output deviations from the target or set point. We consider an alternative EPC model with second-order autoregressive disturbance. We compare three control systems; EPC, EPC combined with EWMA. This paper shows through simulation that tlhe performance of the integrated model of EPC and EWMA is more preferable than that of EPC.

The recent huge maritime casualties and their environmental impacts showed that human error in ship navigation is one of the primary causes leading to accidents. In order to reduce maritime accidents and human errors in ship navigation, it is very important and urgent to improve the skills of navigators and develop advanced navigation support system for ship operations. For example, a SCMS(Ship Control and Management System), INS(Integrated Navigation System) and PCS(propulsion Control System) which are considered as a ship automation system was operated in ship. Furthermore, the most recent automation ships collision incidents warn us that only making automation ships alone is not sufficient for improving ship safety. Effective interaction between officer and ship automation system is essential for safety. In this paper, the interactive relationship between officer and the ship automation system was studied, then the research result for reducing maritime casualties will be presented.

Concerns about food safety continue to rise and under this situation, governments of some countries have reinforced their regulations more strictly for food safety. In order to prevent food safety incidents or, at least to minimize the impact, the preparedness is very important. As a consequence of this, traceability system has become an essential tool for food safety. Recently, it requires more prevention-based food safety control system. One of the most generally used systems for food safety control is Hazard Analysis and Critical Control Point (HACCP). Both traceability and HACCP systems can be integrated through Electronic Product Code (EPC) Sensor Network technologies which have four value propositions. In this paper, we will introduce the concept of product and process traceability system (P2TS) through the integration of three systems to improve food safety management. The final aim is to find out the added values of the P2TS.

According to the COVID-19, development of various medical software based on IoT(Internet of Things) was accelerated. Especially, interest in a central software system that can remotely monitor and control ventilators is increasing to solve problems related to the continuous increase in severe COVID-19 patients. Since medical device software is closely related to human life, this study aims to develop central monitoring system that can remotely monitor and control multiple ventilators in compliance with medical device software development standards and to verify performance of system. In addition, to ensure the safety and reliability of this central monitoring system, this study also specifies risk management requirements that can identify hazardous situations and evaluate potential hazards and confirms the implementation of cybersecurity to protect against potential cyber threats, which can have serious consequences for patient safety. As a result, we obtained medical device software manufacturing certificates from MFDS(Ministry of Food and Drug Safety) through technical documents about performance verification, risk management and cybersecurity application.
