There exists dead zone from the aspects of health equity and health medical equity for maritime personnel. They could not have been benefited from disease prevention and health promotion in comparison with shore personnel due to the restricted medical accessibility caused by long voyage ship operation. Furthermore, the system of health management and medical assistance for maritime personnel is insufficient, the continuous health monitoring system does not exist, nor health diagnosis system, maritime industrial accidents and occupational disease control systems are adequate. The International Maritime Organization and the International Labour Organization recommend their Member Governments to take necessary measures in the management of seafarers` health and diseases through conducting continuous and systematic investigation. Thus, this study intends to propose action strategy and tasks for introducing marine telemedicine system aiming to provide seafarers with health management service for the years to come. The conclusions of this study can be given as follows. First, it is required that a systematic medical service system needs to be provided to promote seafarers` health. Second it is recommended to establish the marine telemedicine system incorporating U-Health technology. Third, it is necessary to revise the relevant laws and regulations to introduce the marine telemedicine system. Fourth, it is also necessary to provide various assistance system at the national level in the furtherance of global marketing of marine telemedicine system.

DOI : 10.13000/JFMSE.2015.27.5.1236
This study examined understanding and attitude of sustainable development(SD) of 38 college students in a nuclear power plant construction after education for sustainable development(ESD) through panel discussion. The results were as follows: First, after lesson 66% of students were expected that SD is possible if scientific technology is developed and a frugal life for the protection of environment is carried out. However, the remaining students regarded SD as an ideal concept, because they thought it is not possible to pursue environmental sustainability and socio-economic development simultaneously. Second, students` opinions in the evaluation of constructing a nuclear power plant in three aspects(environment, society and economy) before and after panel discussion were changed as follows; 1) After panel discussion, the objectors increased to 21% in economic evaluation, while the supporters increased to 11% in environmental evaluation. 2) Students majoring in engineering or natural sciences changed their opinions to agree in environmental evaluation because they considered a nuclear power plant safe and eco-energy. However students majoring in social science/business or liberal arts/arts changed their opinions to disagree in economic evaluation because they considered a nuclear power plant as high-cost energy when assessing danger-accidents cost, public consensus cost, operation and maintenance cost, and waste disposal cost. 3) This change of decision-making in students majoring in social science/business or liberal arts/arts after panel discussion was statistically significant(p<0.05). Implications of panel discussion as a teaching and learning method in ESD are also discussed.

DOI : 10.13000/JFMSE.2015.27.5.1252
This study examined the moderating and mediating effects of teacher-child conflict relationship among child`s language ability, emotional regulation and peer victimization. The participants were 152 children(77 boys, 75 girls) and 14 preschool teachers. The teachers completed rating scales to measure the child`s emotional regulation, peer victimization and teacher-child relationship. Child`s language ability was assessed by researcher using PRES(Preschool Receptive-Expressive Language Scale). The collected data were analyzed using Pearson correlations and hierarchical multiple regressions. Results showed that peer victimization was related to child`s language ability, emotional regulation and teacher-child relationship. Hierarchical aggression analysis indicated that the interaction of child`s receptive language ability and teacher-child conflict relationship predicated peer victimization. Child`s language ability, whose demonstrated a lower teacher-child conflict relationship, was significantly with peer victimization. In addition, the association between a child`s emotional regulation and peer victimization was partially mediated by teacher-child conflict relationship.

Institutional definition instances and necessity of establishment about the geographical scope of the East Sea
KIM, Yun-Bae ; KIM, Kuh ;
Journal of Fisheries and Marine Sciences Education, volume 27, issue 5, 2015, Pages 1380~1394
DOI : 10.13000/JFMSE.2015.27.5.1380
This paper deals with the geographical scope of the East Sea introduced by major domestic institutions. The East Sea surrounded by South Korea, North Korea, Russia, Japan has a variety of marine resources, and is the very appropriate natural laboratory to study future global changes as a miniature ocean. However, there is a continuous conflict between Korea and Japan over the name of the East Sea because of the nature of international waters. So we need the active research achievements based on the exact geographic knowledge of the East Sea to promote the legitimacy of the East Sea in the international community. Nevertheless each domestic institution has a different way to define the southern border of the East Sea so that it showed a difference about linear distance of up to about 44 km. Also, they have defined the scope of East Sea not as the entire East Sea surrounded by South Korea, North Korea, Russia and Japan but as the jurisdiction of the Republic of Korea. It caused serious confusion about accurate statistical knowledge about East Sea such as area, volume, and mean water depth. Therefore, clear social consensus about the geographical scope of the East Sea would be required, there is also the need to institutionalize a legal order to spread it.

This study aimed at exploring, based on the current states and status of onboard training ship, plans to improve the boarding training management for fisheries high school. The results were as follows. The problems with the management of onboard training ship were summarized as the following four types. Firstly, The most training ships throughout the country became superannuated. Secondly, the safe equipments for training ships were necessary to compensate the defects to fall short of the international safety management standards. Thirdly, the problems could result from the dualized system between ownership and management, since training ships were owned by metropolitan and provincial education offices and operated by management centered schools. Fourthly, middle technicians such as professional fisheries manpower were not easily supplied with. The plans to improve the above problems were as in the following. Firstly, support and help of Ministry of Maritime Affairs and Fisheries were needed to launch new onboard training ships which substitute for the superannuated. Secondly, new onboard ships were required to be launched according to the updated international safety management standards. Thirdly, Korea Institute of Maritime and Fisheries Technology should hold onboard training. Fourthly, on-site onboard training expertise, systemic management, safety, etc. should be compensated through industry-university-institute collaboration.

This research paper looks into the interrelationships between physical self-perception, performance confidence, physical self-efficacy, dance flow and dance performance satisfaction with dance major students as the central figure. It also looks into the needs of dance majors, and in order to understand the accomplishment in dance and performance satisfaction, studies were carried out on 313 dance major students. According to this research, firstly, in the difference from physical self-perception according to general characteristics, specialists that major in dance have perception about one`s body when specialists have a longer dancing time and experience. In the relationship between dancing experience and self-efficacy it could be seen that self-efficacy is postirely comelated with dancing experience. Also, in dance performance satisfaction, the more experience or time one encounters dance the higher the satisfaction. Secondly, when looking at the effect physical self-perception has on performance, confidence and self-efficacy, among the lower factors of physical self-perception, sports competence, condition and fitness have notable amount of effect on performance confidence. Thirdly, when looking at the effect on physical self-perception and self-efficacy, sports competence and condition have a certain amount of influence on body competence. Also sports competence, condition and fitness have some influence on physical confidence. Fourth, when looking at the influence of performance confidence and self-efficacy on dance flow, performance confidence, body competence and physical attraction have some effect on behavioral devotion. Lastry looking at the influence dance flow has on dance performance satisfaction, only behavioral devotion has much influence on dance performance satisfaction.

Olive flounder (Paralichthys olivaceus) including red seabream (Pagrus major) and jacopever (Sebastes schlegeli) were known to be suitable characteristics for preparing a processed food because of white meat fish containing low fat in muscle. In this study, the physicochemical properties of olive flounder (46-50 cm of length, 950-1,050 g of weight), red seabream (30-33 cm of length, 1,250-1,350 g of weight) and jacopever (20-23 cm of length, 550-650 g of weight) were studied to obtain a basic data for the development of a new processed food. Head, scale, bone and viscera of each samples were removed, and then grinding with homogenizer before experiment. Moisture content of red seabream is lower than that of olive flounder and jacopever, therefore, crude protein and crude lipid are higher content. Red seabream showed higher redness, yellowess and color difference value than those of olive flounder and jacopever except lightness. The major total amino acid in olive flounder, seabream and jacopever were glutamic acid, lysine and aspartic acid in order. Especially, the highest content of free amino acid was lysine for olive flounder and jacopever and alanine for red seabream. The highest content of mineral in olive flounder, seabream and jacopever was potassium (K) and then phosphorous (P) and sodium (Na) in order. The highest amount of fatty acid in olive flounder, red seabream and jacopever was polyenoic acid in which especially contained 6.8, 7.1 and 6.7% for EPA, and 15.2, 15.2 and 17.1% for DHA, respectively. From the result of sensory evaluation, there was no significant difference in color and odor, but not in taste and texture.

Adjuvant is an immune enhancer commonly used during vaccination to enhance the host immune response. In the present study, we produced the several recombinant protein from immune related gene of olive flounder (Paralichthys olivaceus). Especially, to produce the soluble type of recombinant protein, we constructed the MBP (Maltose binding protein) fusion G-CSF (Granulocyte colony stimulating factor) recombinant protein among the flounder immune related genes. To verify the immune stimulatory effect and safety of this recombinant protein (rPoGCSF), expression changes of several immune genes were tested using quantitative real-time PCR method with gene specific primer from flounder head kidney leukocytes. As a result, we confirmed that the rPoGCSF has an ability of immune stimulatory effect, also it has broad range of pH and temperature.

This study analyzed the fishery and maritime vocational high school teachers` recognition on the outcomes and future agenda. In addition, it delineates the importance of the vocational education division being carried out for 10 years in the College Scholastic Achievement Test (CSAT). In order to gather relevant information, 76 teachers who work in 12 different fishery and shipping vocational high schools around the country were surveyed. The findings of the fishery and maritime department teachers` recognition on the matter are as follows: First, the biggest impact the vocational education division in the CSAT had was on the promotion of continuing education and on the fulfillment on the vocational high school students` desire to compete and enter universities. Second, the CSAT with the vocational education division allowed students to choose a variety of paths after high school whether they be full-time employments or pursuing a degree in universities. Third, the biggest obstacle for the vocational education division in the CSAT is in the most metropolitan universities not honoring the CSAT scores as a criterion in the admission process.

In this study we investigated the effect of vaccine efficacy and immune activities by feeding additives several natural herbal remedies extracts of Sweet Wormwood (Artemisia annua), Galla Rhois, Oriental raisin tree (Havenia Dulicis) and 6-mixed herb to Oilve flounder, Paralichthys olivaceus. Each group of fish fed with the herbal remedies added feed and basic formula during the seven weeks and vaccinated with Edwardsiella tarda Formalin killed vaccine after 4 weeks feeding. Relative Percentage Survival values (RPS) in the group was assessed by the challenge with E.tarda. All groups with the herbal remedies added feed enhanced growth rate, but there were not significantly different in lysozyme activity and agglutination titer. In a challenge experiment with E.tarda, RPS in the all groups feeding additives natural herbal remedies was higher than that of the control group. These results suggest that the natural herbal remedies extracts of Sweet Wormwood (Artemisia annua), Galla Rhois, Oriental raisin tree (Havenia Dulicis) and 6-mixed herb would be effective to enhance efficacy of vaccination to Olive flounder.

The aim of this study is to research on the recognitions and preferences of Puffer fish consumers with the recently increasing well-being trend. To carry out this research, the main analysis was focused on two specific points: how much consumers perceive swellfish and which kinds of Puffer fish foods are preferred by consumers. Although the consumption of Puffer fish is gradually expending, at the same time, there are also numerous obstructive elements in consuming swellfish. In this regard, this test on Puffer fish food will be able to contribute to show an outlook for the Puffer fish food market in the future and to promote consumption of Puffer fish as well. Methodologically, a statistical research was adopted to find out how people understand Puffer fish and the patterns of their choices and intensive examinations were conducted throughout the collected questionnaire. For a more effective outcome, it was necessary to divide into two groups, the Nation`s capital area with Seoul as a center, the most densely populated area and Busan, the biggest marine products consumption area, examining the inclination to consume with regions. In the concrete, the detailed research survey on the Puffer fish were performed with the opinions of the five hundred people from capital area and the five hundred people from Busan area. The difference and common features of consumer`s recognition about Puffer fish food were founded through cross analysis according to age, gender, regions, and income. In conclusion, this research showed the difference tastes and recognition standards toward Puffer fish among consumers from Seoul and Busan areas. If it is possible to apply this result to the efforts of improving supplier`s understanding about Puffer fish consumers` features and cultivating new Puffer fish items, it could contribute to the further consumption of Puffer fish food in the long term point of view.

Vibrio harveyi is a pathogenic marine bacterium causing systemic symptoms resulting in mass mortalities in fishes and shrimps in aquaculture. Outer membrane proteins(OMPs) are related to the pathogenicity and thus good targets for diagnosis and vaccination for Gram negative bacteria. Recently vaccination strategies using the OMPs have been suggested to control vibriosis in several fish species. In this study, we have isolated V. harveyi from diseased marine fishes from different regions of Korea and investigated genetic variations of four OMP genes including OmpK, OmpU, OmpV and OmpW. Consequently, OmpK and U genes could be divided into 3 subgroups of type I, II, III and type A, B, C, respectively, without any correlation with geographical regions and species while OmpV and W were highly homologous. OmpW gene of V. harveyi FP4138 was fully sequenced and predicted the deduced amino acid sequence to form
with hydrophobic channel. Indeed, the immunogenicity of recombinant OmpW produced in Escherichia coli was assessed by vaccinating flounder. As a result, the high antibody response with antibody titer of
and protection with relative percent survival of 60% against artificial infection of V. harveyi were demonstrated. This result indicates that OmpW is a virulence related factor and it can be a vaccine candidate to prevent a high mortality caused by V. harveyi infection in olive flounder, Paralichthys olivaceus.
