The purpose of this study was to evaluate and maximize the value of Dokdo as a marine educational tourism destination. The purpose of this study was to contribute to the identification of Dokdo as a unique territory of Korea rather than a disputed territory by further activating Dokdo tourism. The revitalization of Dokdo tourism was reviewed and analyzed from the viewpoint that it is possible when Dokdo is recognized as a destination for marine educational tourism. As a result of reviewing various research papers, periodicals, and government documents published in Korea and abroad, it is necessary to emphasize on-site education such as patriotism, anti-Japanese consciousness, and historical awareness in order to maximize value as a marine educational destination of Dokdo. Points out that it is possible to differentiate from other tourist destinations. Second, it pointed out that Dokdo preserves and develops to maximize the resource value of various tourism resources it possesses. Third, it pointed out to develop specialized tourism resources that can be linked with Dokdo tourism. Fourth, it pointed out that Dokdo will maximize its development potential as a marine educational tourism destination. Fifth, it is pointed out that there is a need to improve the educational program related to Dokdo. Finally, I pointed out that I would like to develop a variety of marine educational tourism contents and tourism programs linked with Ulleungdo.

Two unrecorded fungi, Diaporthe perseae and Fusarium falciforme, were isolated from soil sampled from Dokdo in Korea. There have been many reports of Diaporthe sp. and Fusarium sp. in mainland Korea but none of them have reported in Dokdo so far. We used the morphological features and two molecular markers including the internal transcribed spacer and translation elongation factor 1-α region to compare and analyze these species with the closely related taxa. As a result, we confirmed that these fungi were unrecorded soil fungi in Korea. Then, the cultural and morphological characteristics such as the conidia of these two fungal species could be clarified. These results are expected to help us to understand the distribution of fungi in Dokdo and manage the Dokdo Island Natural Reserve.

Since the Shimane Prefecture government in Japan enacted "Takeshima Day" in March 2005, it has held commemorative ceremonies with Japanese politicians present each year on February 22. Japan has marked Dokdo as its territory in elementary and middle high school textbooks, and the number of such references has been increasing in recent years. Shimane Prefecture, which is the area nearest to Dokdo is strengthening Dokdo education in its geography classes at elementary and middle schools as part of regional studies. The study and education on Dokdo was begun by social studies teachers in the Oki Islands in Shimane Prefecture, but now extends throughout the prefecture. The auxiliary educational materials regarding Dokdo produced in Shimane Prefecture include teaching guidelines for teachers, worksheets for students, CDs containing statistics and picture files, and two kinds of DVD movie clips for each grade. In particular, schools teach the damage to the Japanese fishery industry caused by Korea's illegal occupation of Dokdo. This will likely form anti-Korean sentiments among Japanese students. It is hoped that Korean and Japanese scholars will work together to develop Dokdo auxiliary textbooks in order to improve the correct historical understanding of Dokdo.

We believe, 'Dokdo is clearly an inherent territory of Korea, in the light of geographical and historical facts', This paper aims to discuss Japanese multidimensional approach on the Issues of Dokdo(Takeshima) in the context of Territory Education. We considered the matter from various angles that supported by the ministry of Foreign affairs and the ministry of Education in national scale, as well as shimane prefecture government and municipality scale. Therefore, It is likely that the approach of territory education on Dokdo in Japan is variable and potential, and is temporary state of condensation, depends on Korea-Japan's political, economical, social, and international conditions. More studies of the new approach must be done for the new implications of Territory Education that embraces all meanings and events according to the disposition of neighbouring condition of Dokdo in world context, keeping out emotional and nationalist sympathies. The result of consideration in this paper are as follows. First, Territory Education in japan was focused on geography, history, Civil, Social Studies, compared with focusing on History in Korea. Second, It is centered on "korea is illegally occupying Dokdo, against which Japan has been consistently making strong protests" rather than simple historical approach. Thirdly, Their approaches seek to be succeeded the identity and importance of Territory Education to next generation rather than the present solving problem.

We extensively observed macroalgal assemblages of species composition and biomass of summer benthic marine algae at Dokdo in the East sea of Korea. A total of 102 species (12 Chlorophyta, 36 Phaeophyta, and 54 Rhodophyta) were identified in quadrats and were analysed qualitatively to define the variation patterns. Biomass in dry weight according to various depths ranged between 146.0 to 764.2 g m-2 at study sites. Mean biomass at the investigated sites was greater in the 10m depth range than in the 5 and 15m depths at Dongdo. The flora could be classified into six functional groups: coarsely branched form (51.0%), filamentous form (17.7%), thick leather form (15.7%), sheet form (5.9%), jointed calcareous form (4.9%) and crustose form (4.9%). The R/P, C/P and (R+C)/P value were 1.67, 0.50 and 2.17, respectively. The number of marine algae species and the biomass in Dokdo area were markedly reduced as compared with those in the previous studies. This result suggests possible future changes in the algal vegetation, considering coastal marine environment of this area.

In this study, arbuscular mycorrhizal fungi (AMF) were isolated from rhizosphere soils of Dokdo Island. Based on their morphological characteristics and 18S rDNA sequence analysis, eight species belonging to seven genera were identified: Acaulospora longula, A. mellea, Claroideoglomus claroideum, Diversispora aurantia, Funneliformis mosseae, Gigaspora margarita, Paraglomus occultum, and Septoglomus constrictum. No differences were noted between the AMF isolated from Dongdo and Seodo in Dokdo Island, and all of these AMF have been reported previously in Korea. These results could be useful for diversity and functional analyses of AMF in Korea.

Although Dokdo, small and dependent islands of Ulleung County, can be considered critical in terms of both geo-politics and physical geography, it is clear that Korean geographers have been too silent tn study Dokdo. In the author's view, such tendency is partly due to difficulties in access to Dokdo. In this sense this study would be meaningful for inquiring into the regional geomorphology of Dokdo regardless of only three-day field work. The major findings of the study are as follows. Firstly, the geology of Dokdo is composed of 8 rock units. Secondly, in a slope analysis of Dokdo volcano using GIS tool, steep slopes over $26^{\circ}$ account for 79.1% of whole slopes and even free faces, defined as slopes over $40^{\circ}$, account for 65.4%. Thirdly, the main landforms of Dokdo constitute volcanic landform, coastal landform and the others, such as talus, dyke, tafoni and erosional hollow. Fourthly, it turns out that advanced landform classification map of Dokdo can be designed by taking an approach tn regional geomorphology. Finally, based on a detailed review of the latest geological literature, I argue that part of landforms of East Dokdo(dongdo) is closer tn an erosional hollow than a small crater.

This study is about the Novel Engineering(NE) education program : a class model that combines reading and engineering. By including the process of directly designing and programming a virtual reality using CospacesEdu (a VR authoring tool for the NE class), the effects of the educational program on learners' STEAM literacy and Learning immersion are demonstrated. Moreover, the subject of this education is Dokdo in South Korea. As a result, the average of STEAM literacy is increased, and a significant change is confirmed statistically in Convergence. Learning immersion shows significant improvement in Challenges-skills balance. On the other hand, some students experience difficulties due to the long research stages, from reading a book to researching for information to designing VR and rewriting a story with the collected information. In conclusion, this study will help generalise other education using NE, and this developed program will be a reference that would suggest a new way of teaching.

Two unrecorded marine nematode species, belonging to genus Paracanthonchus Micoletzky, 1924, are described on the basis of the specimens collected from rocky intertidal seagrass bed on the eastern coast of Korea. Paracanthonchus macrodon (Ditlevsen, 1918) is characterized by presence of cuticular differentiation, strongly dilated gubernaculum with numerous cusps, three post-cloacal setae, and arrangement of six (4+2) precloacal supplement. Paracanthonchus kamui Kito, 1981 is distinguished from other species of the genus by having the 4.25 turns amphideal fovea, six tubular supplement, rib-shaped gubernaculums with proximally hook-shaped and distally broaden. In this study, we provide taxonomic description and illustration of two unrecorded species of the genus Paracanthonchus by differential interference contrast microscopy. This is the first report on the species of the genus Paracanthonchus from Korea.
