The purpose of this study is to design of prototype for developing webpage of fisheries and marine education especially in the field of Busan area. For this, we extract the guideline for development from literature review, need and task analysis, and advices of subject domain experts. Followings were the results of the research: (a) We make the prototype for main menu and screen based on institute, time, subject, and location. (b) We make the prototype for program approach guide, which is consisted of location based menu constructing prototype guide, activation prototype guide, and selection prototype guide. (c) We make the prototype for functional guide, which is consisted of information section, participation section and other sections.

Environmental differences of each sea around the Korean Peninsula in terms of factors including topography and complexity of sea current may influence species and genetic diversity of marine fishes. Fish are naturally abundant in the frontal area where various currents or water masses meet. However, this food resource is prone to human overexploitation, threatening the marine ecosystem. New fisheries resources management strategies are needed. Such strategies require information about population structure obtained through morphological and genetic methods.

Understanding dietary habits is one of the most important factors in studying food webs and other ecological processes. Here we designed universal primers to amplify portions of the 18S and 28S rDNA sequences to examine gut contents using PCR techniques. The gut contents of sailfin sandfish (Arctoscopus japonicus) and pacific squid (Todarodes pacificus) were examined. In total, 11 families of prey were identified with 18S and 28S rDNA using the universal primers. The DNA sequence data indicated that the primer sets successfully amplified a wide spectrum of species and represented gut contents in a relatively convenient way. We found that information in the NCBI database was not yet sufficient to discriminate the species we isolated. In addition, technology for the separation of heterogeneous PCR products and better resolution and quantification protocols would help increase data accuracy.

The gundrill is capable of machining for having large length to diameter ratio in single pass. The techniques of gundrill and gun boring began developing in the late 18th century with the need for more accurate bores in rifle, cannon, machinery part and marine part etc. The main feature of the gun drilling provides a stabilizing cutting force resultant necessary for self guidance of the drill head. A study of the accuracy and surface finish of holes produced would reveal quite useful information regarding the process. The thesis deals with the experimental results obtained during gun drilling on marine part materials for different machining conditions.

The aims of this study are to analysis the elements associated with a occupational basic competencies of fisheries and maritime high school students. Fisheries & maritime key competencies were defined as the abilities that include the essential knowledge, skills, attitude, and experiences required for the workforce on the fisheries and maritime job condition. This research collected preliminary data from 177 fisheries & maritime high school teachers. Data were analyzed to obtain item quality, reliability and validity analysis. The results of the study were as follows; First, largely, fisheris & maritime key competencies were divided into two parts; basic vocational skills and fisheries-maritime job skills. Second, fisheries & maritime key competencies were consisted of communicative competence, numeracy skills, thinking skills, English communication skills, self-management skills, interpersonal competency, selection & application of alternative, marine technology & information skills, marine consciousness and maritime professional ethics. Third, each key competency consisted of 2-9 sub-competencies.

Morphological and molecular information of two marine algae collected from Korea is given. One belonging to a green alga, is characterized by small size up to 4 cm high, much branched thalli on all sides, slender and linear branchlets which is constricted near base, axes without prominent branch scars, chloroplasts with a prominent central pyrenoid. The other, as a brown alga, is distinct from other Korean species in having cylindrical elevated projections at all parts of thallus axis, leaves with slightly serrulate margin together with distinct midrib bearing spines and absence to rarely occurred vesicles. In phylogenetic tree based on rbcL sequences, these two species are nested in the same clade with Bryopsis triploramosa and Sargassum polyporum, respectively. In this study, these two species are newly recorded in the Korean marine algal flora based on the morphological and molecular data.

Various countries around the world are conducting various studies to apply information and communication technology to marine safety. Based on this, the International Maritime Organization (IMO) has established the e-Navigation standard to apply the latest information and communication technology to marine services. In Korea, the Ministry of Maritime Affairs and Fisheries is promoting Korean e-navigation considering domestic marine environment and is trying to apply LTE communication method as a high-speed wireless communication method at sea. In this paper, we describe the development of an LTE based marine router system supporting 700Mhz frequency band allocated for high speed maritime wireless communication service. Experiments on the possibility of 100km distance communication from base station using LTE based ship router are shown. LTE - based high - speed maritime wireless communication router system can provide communication infrastructure necessary to develop various accident prevention technologies that may occur at sea.

The integrated navigation system(INS) for fishing boat which organized the marine radar, global positioning system(GPS) compass, automatic identification system(AIS), echo sounder, GPS and electronic nautical chart(ENC) was manufactured to reduce the marine accidents of fishing boats occurred frequently at coastal and offshore. The application possibility of INS for fishing boat was examined for basic experiments in the sea. Integration display of various information, such as other vessel's behavior, depth, own vessel's position etc. was done to help the operate user who understood the circumstance around own boat. Therefore, the system will be utilized as a useful equipment for safety voyage and fishing work on the fishing ground.
