Most of the traffic accidents are a rear-end collision and a clash generated in the signalized intersection on the local roads. So, it is demanded that the high-quality of signal control and dilemma zone control. According to the cases generated by foreign countries, we established the strategies which are composed of Volume-Density Control, strategy of the dilemma zone control using R-detector (microwave detector) In Japan and EC-DC Control. MOEs(Measure of effectiveness) are car numbers in the dilemma zone , max-out probability in the safe side and the average stopping delay in the progress side. We choose a signalized intersection in rural highway to analyze the effect of the strategies and practiced an on-the-spot survey. The result of the survey is applied to the basic data in the simulator. Consequently, strategy of the dilemma zone control using R-detector(microwave detector) in Japan is the best effective in the safe side and EC-DC control is the best in the progress side. Based on the result, we developed the effective strategy of the signal control . This strategy is composed of the strategy of Japan and the detector on the stopping line used in the EC-DC control. On the result of the analysis, new strategy is the best effective in two sides.

The purpose of this study is to suggest the strategies of building disaster resistant communities to overcome communities destruction and vulnerability caused by the Hebei Spirit oil spill accident in Taean on December 7th, 2007. For accomplishing the purpose, we drew problems of approach based on context of community, governance strategy, and community-based approach. And based on the results of this analysis, suggestions were made as follows for building disaster resistant communities. First, when Hebei Spirit oil spill accident occurred we have been short of regional study and unreality of regional safety plan. For overcoming this points, we have need of activation of regional study and establishment of regional safety plan based on the bottom-up approach. Second, while the spill has brought a milestone activation of volunteer, we have not still efficient disaster management based on governance. So we have to establish network-governance to cooperate with government-business-private sector for efficient disaster management. Third, we argue that it is important to build social capital such as social networks, social contacts for community-based disaster resistant communities.

In this study, 1,474 effective patents were derived for quantitative analysis of five major countries, including Korea, China, Japan, the United States and Europe, for marine space policy simulator technology used as a support for integrated marine space management means, and domestic technology competitiveness and domestic and foreign technology trends were identified through annual and national patent application trends and word cloud analysis. This diagnosed the need for active policy support for research and development of marine space policy simulator technology at the government level and preparation through linkage strategies such as patent application consideration and standardization preoccupation for surrounding technologies to prepare for China-led market monopoly and preoccupation.

At the 80th session of the MEPC, the IMO presented an enhanced GHG reduction strategy. The strategy is more specific and robust than the initial strategy presented at the 72nd session. The IMO aims to achieve 'Net Zero' GHG emissions from international shipping by 2050. In this study, a risk assessment was conducted for representative green fuels, namely. LNG, hydrogen, methanol, and ammonia. The fuzzy method was used to resolve the subjective ambiguity of results from the survey of the experts, and the positive and negative ef ects of the fuzziness were derived through the TOPSIS method. Finally, the closeness coefficients of the considered alternative fuels were determined using the Vertex method. As a result, methanol, LNG, hydrogen, and ammonia were preferred. This study suggests that the proposed approach can be used as a collective decision-making tool for selecting alternative fuels.

Safety accidents in university laboratories are constantly occurring due to various chemical, physical, and biohazard risk factors. In this study, the trend of accident occurrence and correlations between factors were derived through statistical and cross-analysis of 192 accident cases in university labs between 2016 and 2020. Directions and strategies were prepared from the correlations of major factors, and guidelines for improvement of the laboratory safety management system were suggested by comparing and analyzing existing policy directions for laboratory accidents.

Recently, International Standardization is an important issue in competitive world market because of integration of standard, liberalization of international trade and globalization. Consequently, Korean companies need a strategy about corresponding to market circumstance and global standard. In this study, we examine Intellectual Property, Patent and Antitrust Law which are related to standardization. This study suggests company strategy and system integration model to dispose the global standard.

최근 기업들은 인적·물적 손실, 수입감소, 배상책임 등의 위기에 직면하고 있다 실제 경영에서는 가시적으로 나타나고 있지 않으나, SHE(Safety of Health & environment)과 이상기후 및 기상변동에 의한 대형사고, 자연재해가 증가하고 있다. 각종 대형사고, 공해문제, 소비자문제 등은 기업의 내·외에서 발생하고 있는 문제들이 기업의 부도덕한 행위로 인식되면서 기업의 사회적 책임을 묻는 사례는 증가하고 있는 실정이다. 이러한 결과는 기업에 대한 부정적 국민의식과 함께 사소한 일이라도 쟁의 소송으로 발전하거나 단순한 종업원 개인이 기업외부에서 일으킨 사고까지 기업이미지와 직결되고 있다(중략)
