  • This paper discusses the evaluation of the safety impact of the Adaptive Cruise Control (ACC) system in Korea. To evaluate the safety impact, this paper suggests an analysis method by using the test scenario and field operational test data. The test scenario is composed to represent the main component factor of the ACC system and ACC related accident situation such as rear-end collision, lane-change, and road-curvature, etc. Also, from the field operation test data, the system's potential to increase the safety can be measured ideally. Besides, field operational testdata was used to revise the expected safety impact value as Korean road conditions. By using the proposed evaluation method, enhanced safety impact of the ACC system can be estimated scientifically.

  • Small vessels of less then 20 tonnage and leisure boats such as motor boats, sailing yachts, water motorcycle, etc have been excluded from the rules and regulations such as Marine Leisure Safety Act, Ship Act and Ship Safety Act for a long time in Korea. As a result, these small vessels and leisure boats have remained within the blind area of maritime safety and environment protection. Among these vessels and boats, some leisure boats such as motor boats of 20 horse power or more(excluding motor boats equipped with engine inside the vehicles), water motorcycles and rubber boats of 30 horse power or more are incorporated into the Marine Leisure Safety Act through the registry, safety inspection, insurance early 2005 in Korea. In relation to the scope of application of the national Acts concerned, I consider the conflicts between Acts and suggest the subordinate enforcement ordinance and regulations.

  • Traffic Accident Merging Index (TAMI) is developed for TMACS (Traffic Safety Information Management Complex System). TAMI is calculated by combining 'Severity Index' and 'Frequency'. The existing indexes are Traffic deaths per 100,000 population, Traffic deaths per 100,000 inhabitants/per billion veh-km, etc. However, there is no consistency in using them among local governments, so it can create confusion. Moreover, the index level is too complicated to understand. Therefore, this study suggests new traffic safety index, TAMI. It will work to improve the weaknesses and present accurate status of traffic safety in local governments.

  • The curved portion fur each section running safety evaluation interpretation according to the track condition for improving the curved portion passage rate of a vehicle by using the multibody analysis model of the Saemaeul train was carried out. As a result, The excess of cant reaches the bad effect to the running safety in case the radius of curvature is small. In case the radius of curvature was large, we could confirm that the deficiency of cant reached the bad effect to the running safety. In the curved portion, the circular curve section most badly showed the running safety. The deficiency of curve length reaches the bad to the running safety. In the curved portion, the circular curve section most badly showed the running safety. Therefore the track condition(cant, transition curve length, etc) can reach the bad effect to the running safety of a vehicle, the exact design is required.

  • This paper proposes a novel safety autonomous platform (SAP) architecture that can automatically and precisely manage on-site safety through ensemble artificial intelligence models generated from video information, worker's biometric information, and the safety rule to estimate the risk index. We practically designed the proposed SAP architecture by the Hadoop ecosystem with Kafka/NiFi, Spark/Hive, Hue, ELK (Elasticsearch, Logstash, Kibana), Ansible, etc., and confirmed that it worked well with safety mobility gateways for providing various safety applications.

  • This study is about safety education experience and practice of parents who are raising preschool children and the study results are as the following. For safety education experience state, parents had experience of safety education and mostly received it through communities, TV, Internet, etc. The most common educational content was the traffic safety education. For safety education practice degree according to number of children, safety education practice was mostly done well with 1~2 children. For safety education practice degree according to family type, safety education practice degree within the family was done most in nuclear families while healthy life habit safety education practice degree was done most in nuclear families and reconstituted families. Also, for traffic safety education practice degree, it was done well in nuclear families. For respiratory disease safety education practice degree, nuclear families and reconstituted families were the highest and for first aid safety education practice degree, single-parent families were the highest. For safety knowledge level of parents, safety knowledge of family was the highest, followed by safety knowledge of respiratory disease, and traffic. For safety education practice degree and safety knowledge according to safety education experience of parents, there was a significant difference in practice degree according to safety education experience of parents and there was also difference in practice knowledge according to experience. There was also education effect in healthy life habit safety knowledge and traffic safety knowledge.

  • In the era of digital technology, display device is the one of the important interface tool to communicate and transmit the information. Among the various display devices, CRT is the most popular one. Even though the CRT has many advantages comparing to other devices, it is faced to overcome its a few disadvantages especially in volume, shape and price, etc, In this paper, we try to show the development strategy of CRT corresponding with flat displays in the view point of ergonomics.

  • The fire protection system of Nuclear Power Plants(NPPs) is an integrated system that is applied multi-field technology. So, it needs synthetic design and analysis, that is, the plan of fire protection, fire compartment, fire detection, fire suppression, and success of safety shut down, etc. In case of a fire in NPPs, secure the safety of reactor and minimize the radioactivity contamination. For this purpose, perform the fire risk analysis and make up the deducted problem through the improvement of design or the change of operation process.
