Marine pollution prevention manager system has been operated for the purpose of preventing marine pollution from ships and marine facilities in Korea. As a new "marine environment management act" replacing an old "marine pollution prevention low" had entered into force from January 20, 2008, the education system for marine pollution prevention manager is to change in some ways. Major changes in education/training institutions, education/training courses, trainees, marine pollution prevention manager's works and business, marine facilities and educational subjects are summarized, comparing between old "marine pollution prevention act" and new "marine environment management act".

The purpose of this study is examining an influence of a corporate on processed marine product's purchase intention with moderating effect of consumers' product evaluation adding processed marine product's evaluations as new variable. The hypothesis of a positive influence of processed marine product's corporate image on processed marine product's purchase intension is partially supported. Specifically, product itself, service, reliability, and communication among the factors of a processed marine product's corporate image significantly affect processed marine product's purchase intension whereas corporate social responsibility does not affect processed marine product's purchase intention. Processed marine product's evaluation also positively affects processed marine product's purchase intention. It implies that there are somewhat differences between influences of various factors of a processed marine product's corporate image on processed marine product's purchase intention but are overall influences of a processed marine product's corporate image on processed marine product's evaluation both directly and indirectly. Nowadays, consumer considers not only good quality of product but also its invisible image and value. Therefore, future studies should consider various ways to investigate a processed marine product's corporate image and processed marine product's product evaluation.

We constructed a black rockfish (Sebastes schlegeli) leukocyte cDNA library and a total of 386 expressed sequence tag (EST) clones were generated. Gene annotation procedures and homology searches of the sequenced ESTs were locally done by BLASTX for amino acid similarity comparisons. Of the 386 EST clones, 199 different ESTs showed significant homology to previously described genes while 97 ESTs were unidentified, hypothetical, or unnamed proteins. Encoding 38 different sequences were identified as putative bio-defense genes or genes associated with immune response.

An Independent Administrative Corporation Japan Agency for Marine-Earth Science and Technology (JAMSTEC) is developing light-and-small Autonomous Underwater Vehicles (AUV)$^{1)}$, named 'MR-X1' (Marine Robot Experimental 1), which can cruise, investigate and observe by itself without human's help. In this paper, we consider the motion control problem of 'MR-X1' and derive a controller. Since the dynamic property of 'MR-X1' is changed by the influence of the speed, the mathematical model of 'MR-X1' becomes the nonlinear model. In order to design a controller for 'MR-X1', we generally apply nonlinear control theories or linear control theories with some constant speed situation. If we design a controller by applying Linear Quadratic (LQ) optimal control theory, the obtained controller only compensates t e optimality at the designed speed situation, and does not compensate the stability at another speed situations. This paper proposes a controller design method using Linear Matrix Inequalities (LMIs)$^{2),3),4)}$, which can adapt the speed variation of 'MR-X1'. And examples of numerical analysis using our designed controller are shown.

The purpose of this study was to analyze the ability level of the occupational Basic Competencies of Fisheries and Maritime(F&M) high school students using F&M basic skills scale. In order to achieve the objectives of this study, the level was analyzed with the Fisheries and Maritime ability scale, comparing each grade level & department. This study was applied to the literature and research methods. This research was conducted collecting preliminary data from 1,113 F&M high school freshman and sophomore students. This survey of 46 questions was used to measure for F&M ability scale-divided into 6 areas-marine vocational ethics, marine information capacity, marine elementary knowledge, marine safety management skill, management & utilization marine life and marine consciousness. The results of this study were as follows; First, in F&M high school students' competencies, marine vocational ethics, marine consciousness was higher, marine information capacity, marine elementary knowledge, marine safety management skill were middle, management & utilization marine life was lower. Second, in the grade level, 5 competencies(marine vocational ethics, marine information capacity, marine elementary knowledge, management & utilization life and marine consciousness) were not different, but 2 Grade was higher than 1 Grade in the marine safety management skill. Third, comparing F&M department, Maritime department were higher than fisheries in 5 competencies. But, fisheries department was higher than maritime in the management & utilization life competencies.

In this manuscript the characteristics of marine environmental sciences and technology was depicted in the aspect of marine biotechnology, and the prospect of Korean society of Marine Environmental Engineering were suggested. Firstly definitions and main features of marine biotechnology and marine environmental sciences and technology were mentioned, and the long-term trends of environmental sciences and technology and the role of marine biotechnology to contribute for the development of marine environmental science and technology were described. The present state of the art for domestic research activities in the fields of marine environmental science and technology was reviewed and future directions for developing the Korean Society of Marine Environmental Engineering were suggested and discussed through understanding the present problems and solving those problems.

Environmental damage caused by marine plastic debris occurs and has become a major contributor to marine pollution. This study analyzed the current state of marine plastic debris pollution and proposed essential strategies to reduce damage. To assess the current state of pollution arising from marine plastic debris, this study investigated the properties of plastic debris, reviewed case studies of ecological impacts, and examined the inflow and distribution of marine plastic debris. The results of this study indicate that the major deleterious effects of marine plastics are entanglement and ingestion. In addition, the amount of plastic waste entering the sea was estimated to be 230 Mt in 2015 and may increase to 554 Mt in 2050. In this study, three key strategies were proposed to reduce damage and preserve the ecosystem, including: 1) removing plastic debris in the marine environment, 2) limiting the release of plastic debris to the marine environment, and 3) preventing damage to humans and marine life from plastic debris. To minimize the environmental damage caused by marine plastic debris, the proposed response strategies should be implemented in parallel.
