The sea hare Aplysia kurodai is an economic species located along the Korean coast. This study aimed to investigate the stomach contents of A. kurodai and its relationship with marine algal flora surrounding their habitat. A. kurodai and marine algae were sampled in seven and five areas in the East and the South seas, respectively. The marine algae found in the stomach and surrounding marine habitat were identified. In the East Sea of Korea, 134 species of seaweed were recorded. Thirty-nine species of marine algae were identified in the stomach contents of A. korudai collected from the East Sea of Korea. Seventy-five species of seaweed were collected in the South Sea of Korea. In addition, 26 species of marine algae were identified in the stomach contents of A. kurodai from the South Sea of Korea. Among the stomach contents of A. kurodai, ten sheet,12 filamentous, 27 coarsely branched, and one jointed calcareous form species were identified.

Busan is one of the most popular tourist cities of the Republic of Korea. To develop differentiated urban brand as the nation's flagship maritime city, Busan needs to explore diverse marine tourism stories and develop related contents. For the purpose of developing storytelling as a way to facilitate the maritime tourism of Busan, this study attempted to i) create 'marine leisure Galmaetgil of Busan' contents using 5-step storytelling modules and ii) develop themed tour routes based on the marine tourist contents and related graphic elements such as tour route map and image editing. Galmaetgil is a beautiful trail developed along the coastal line. It is one of the most famous tourist contents of Busan. Based on this asset, Busan would be able to develop its own tourist contents as the nation's proud marine-leisure city. The emotional stories which can draw a great attention from the citizens and tourists and informative storytelling would make people understand and experience marine leisure in a fun and easy.

The marine life culture contents added with fun and learning factors are created in a 3D space, and the development of augmented reality contents concerning marine life resources in islands and the utilization method of experience-based learning are proposed. As a WYSIWYG-based authoring tool, an augmented reality authoring tool was made to easily use a authoring tool through a node structure and drag & drop. Marine life contents add the animation effect through a marker and event factors such as the change of modeling data, and also, they support real experience-based learning with the narration of marine life. Based on around 50 species of marine animals augmented reality contents, a marine animal AR book can be utilized as a textbook for elementary school classes, and as a 3D image education utilizing augmented reality, it enhances a learning effect by allowing realistic observation, various ways of thinking, and the maximum flow.

The aims of this study are to analysis about the contents associated with the ocean environment compared 17 special-subject textbooks to 2 common-subject textbooks, and to make some proposals for construction of contents. The results of it are as follows; 1. Only 17 books among 36 textbooks taught by the fisheries and marine high schools are contained to some contents related with ocean environment. The contents associated with the ocean environment take possession of 90%, 62% each of total pages in the textbooks, 'ocean pollution' and 'ocean environment'. 2. Of compulsory texts, namely, 'general fisheries', 'general ocean' and 'information treatment of fisheries-marine', the former 2 books are composed of 4.5%, 36.2% each relating with ocean environment. But the last one is nothing. 3. Therefore, even a little contents of ocean environment and its conservation, it is necessary to add as the reasonable rate to the characteristics of each book in 36 special-subject textbooks. 4. And also it is shown that the common-subject textbooks,'ocean science', ' earth science I' and 'earth science II', are composed of 35.7%, 10%, 16.7% each. So we'd like to recommend that the contents of ocean pollution and environmental conservation have to add more.

In this study, we propose a marine character prototype study for development of a marine character as digital contents. This study is a precedent study to build a marine character database with the production of digital contents based on "Jasan-urbo". "Jasan-urbo" is a representative cultural heritage that can highlight the value of Korean marine culture as the first illustrated book of marine creatures in Korea. Therefore, we examined the use value of "Jasan-urbo" through the content approach and looked at the visualization for character utilization and then designed a marine fish species classification standard model. Finally, this study proposed the possibility of discovering prototype sources for digitalization of Korean marine creature's resources.

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 purpose of this study is to suggest a plan to promote the tourism of the island by developing the contents of the marine food tourism. Activation of island tourism should begin with developing marine food tourism content. In the viewpoint that the development of marine food tourism content is a priority, previous studies were examined and related cases were analyzed. For this purpose, this study reviewed and analyzed various literature, periodicals, government documents and newspaper articles published in Korea and abroad. As a result of this study, to develop the marine food tourism contents in Korea and to promote the island tourism, it is necessary to develop the marine food tourism contents as representative contents of the island tourism, develop and operate the high value added fusion food tourism product, And the development of marine food tourism products that meet the island tourism paradigm and changes in tourism patterns of tourists.

Until now, most of the Web GIS system has been developed with one-sided service type that provides pre-built spatial information to users. Recently, however, interactive web system is getting attention because users can create directly spatial information contents that meet their needs. In line with this trend, this study had a aim to develop a UGC(User Generated Contents) support system for marine science researchers who can generate spatial data by themselves on the web. The main advantage of this system is that it provides marine survey data and marine spatial information that needed to work for marine science research. Furthermore, it provides the functions of extracting of coastline as point data for their marine study area, and making of the spatial planning map for marine field survey work and marine science thematic maps for exploratory analysis after research survey. Such kinds of interactive UGC support system gives researchers a chance for utilizing marine spatial information more easily. Therefore, it is expected that the improving of the efficiency of research works, as well as increasing of the utilization of marine spatial data.

Effect of artificial illumination on feeding by the rockfish Sebastes schlegeli receiving no synthetic feed in the cage of the Tongyong Marine Ranch was investigated by analysing the stomach contents of 20 individuals every month from October 1998 to July 1999. The fish was found to have fed on naturally available zooplanktons, i.e. Calanus sinicu, zoeae, amphipods and copepodites in October, fish larvae in November-December, nematodes in January, amphipods in February and again fish larvae from May to July. Despite increase in the weight of stomach contents from 260 mg/fish during the initial period of study to 2,173 mg/fish, as many as 70% of the fish were found to have empty stomach during March-April. Weight of stomach contents did not increase with increasing age of the fish. Occurrence frequency was 83-90% for C. sinicus during October-November and >50% for fish larvae during March-April and June-July.
