The international oil majors have been reducing the size of their own oil tanker fleet since early 1980s. Like international oil majors, the Korean refineries are becoming more dependent on tanker chartering rather than tanker ownership for their oil transportation since the 1990s. They also prefer spot charter to time charter and this kind of trend has continued up to now. Consequently, this paper attempted to find the factors influencing changes in tanker fleet composition. To attain the object of the paper, an empirical study is adopted using the ten decision-making factors derived from preceeding studies. The findings are that MARPOL and OPA 90, and transportation costs are the most important factors influencing an oil tanker fleet composition.

Marine casualties and environmental pollution have increased recently. Especially, the rate of incident of Coastal tankers is higher, but the assessment tool for safety management system is lack in this fields. However Oil Major Vetting System being professional assessment tool for tanker is widely applied in ocean going tanker by the worldwide Oil Majors. According to the analysis of the marine tankers' incidents which applied Oil Major Vetting System, the incidents were reduced rapidly for recent about 5 years. Using Oil Major Vetting System is helped to improve safety management and to prevent marine incidents. Therefore if applying a parts of the Oil Major Vetting Systems to the coastal tankers' Safety Management System, the Coastal tankers incidents would be reduced and improved gradually.

This study got a conclusion following by questionnaire individual own recording law from Mokpo, Iksan, Gangneung to the objects to the academic 608 Dental Hygiene students whom had for consciousness investigations about employment overseas of some special college Dental Hygiene students. 1. Regarding the motivating factors to major in Dental Hygiene, most students(51.3%), particularly most freshmen(57.3%), have chosen this major because of more job opportunities than students with other majors. The most common source of information in choosing majors is the Internet(30.8%). 2. Many students have heard about overseas employment, particularly in case of juniors(82.5%). They want to work abroad if they are given the chances(70.6%), which indicates that the Dental Hygiene majors have much interest and positive attitude in overseas employment. 3. The most significant barrier to their overseas employment is the language, and thus the Dental Hygiene majors should improve their language abilities to be more involved in working abroad. 4. Showed the difference that an experience and light oil, the country where wanted to get a job at that tried to listen to relevance about employment of dental hygiene students by a school year abroad about these results, overseas employment noted. 5. While 'foreign language education must become activation' showed average highest, results to have seen relevance about employment time promotion plan overseas of dental hygiene students by a school year showed a difference by a school year.

Therefore, the following question is raised： Why have oil refinery companies, national and international, been much more dependent upon chartered ships than their owned ships since 1980s\ulcorner This paper tried to answer the above question. In so, doing ten decision-making factors for fleet composition of oil tankers are drawn through literature survey on the research topic with questionnaires and interviews to the four big Korean oil refineries.

This study surveyed 244 employees out of a total of 356 graduates from the steel industry in 2015 to February 2019. The employment rate of graduates is POSCO 67.7%, Hyundai Steel 23.8%, POSCO families 13.1%, and Hyundai Steel families 8.5%. The national certificates acquired by each section were surveyed, with 53.1% of metal section, 39.8% of mechanical section, and 7.1% of other section. Preferred national certificates were POSCO, machinery maintenance industry technicians, steelmaking technicians, and Hyundai Steel followed steelmaking technicians, mechanical maintenance industrial technicians. Among other certifications, the national certificate of industrial safety industrial engineer was preferred. In addition, the average number of national certificates per person for major employment is 5.06 for POSCO, 5.35 for POSCO families, 5.29 for Hyundai Steel, and 4.73 for Hyundai Steel families. The average number of national certificates for S-OIL, KEPCO, Poongsan Metal, etc., is 2.51. In conclusion, it was found that the national certificates related to majors are used as the main evaluation data in finding suitable majors and competency for the job when recruiting talents.
