  • Non-native flora of the Ulleung island, located in the eastern part of South Korea, was surveyed as 54 taxa with 16 families, 35 genera, 53 species and 1 variety. Considering the geographical distribution aspects of the island, the flora of the island showed more closely related with Korean Peninsular than Japan. Poaceace (28%) and Asteraceae (24%) represents more than 50% of the non-native flora in Ulleung island, meaning that they have an advantage of seed dispersal and adaptation to new environments. Ulleung island is comparatively small island of vulnerable to the attack of invasive alien plants but presently, it has the least number of non-native plants than other areas in South Korea. Therefore, we need to take much interest in prevention and mitigation of non-native plant in the future.

  • In a population-based study with 4 years of follow up, we evaluated the prevalence of Coxiella burnetii in cattle on Ulleung Island, Korea. In this study, the rates of C. burnetii infection in cattle on Ulleung Island were determined by PCR and were found to be 0.3-1.0% in the period 2011-2014. All 17 C. burnetii partial 16S rRNA gene sequences from PCR-positive cattle were identical and 2 geographic representatives were included in our analysis. The nucleotide sequences of the 2 samples showed high (98.4-100%) identity with C. burnetii sequences obtained from the GenBank. In this long-term tracking study, the number of cattle positive for C. burnetii on Ulleung Island was low. To prevent the transmission of C. burnetii on Ulleung Island, control strategy should include biosecurity improvement in surveillance, livestock management, administering suitable tests before purchasing animals to detect C. burnetii shedders, and restricting movements between herds.

  • In a study of the fungal diversity on Ulleung Island in Korea, three novel strains of Penicillium were isolated. Different sites on Ulleung Island were selected for collecting endophytic fungi, and three endophytic fungal strains showed unique morphological characteristics. DNA sequence of the internal transcribed spacer, β-tubulin, calmodulin, and RNA polymerase II second largest subunit regions of the strains were analyzed and they showed unique taxonomic position from the other species of Penicillium section Sclerotiora. The new strains were named Penicillium ulleungdoense sp. nov. As the novel endophytic Penicillium taxa were discovered in a unique environment, the data could be meaningful for understanding the geographical distribution of Ascomycetes on Ulleung Island.

  • Brown alga Undaria peterseniana has been interested in the commercial scale aquaculture for warm water species development in southern coastal area of Korea. However, this species was classified an endangered species caused by a decrease in habitat and natural population. In this study, inhabit characteristics of U. peterseniana was investigated in their natural habitat of Ulleung Island, Korea. The U. peterseniana population was occurred dense patches at 20~30m depth. Total length of the alga reached 1.0~2.0m and the largest width ranged 10.0~35.0cm during the study. In 2013, habitats of this species increased two sites compared with the previous year and their distribution extended to low depth (10m) of coastal area. In long-term data, seawater temperature revealed a continuous increment by strong going north of East Korea Warm Current or Ulleung Warm Eddy turning around the coast of Ulleung Island. It suggested that habitat extension of U. peterseniana may be caused by suitable settlement condition and increase of warm water around the coastal area. Current studies of this species may be continuously required in the possibility of fisheries resources as aquaculture species and index species of increment of water temperature at the fixed monitoring site in East Sea. This is the first study to research ecological feature U. peterseniana population at the natural habitat of Ulleung Island.

  • Objectives: Yearly, annual report of cancer patients in Korea is released by National Cancer Center. But, this report is focused in all of the patients in nation. So, there is needed to modify and analyze this report to be used properly for local resident. In Ulleung island, local county and Ulleung medical center don't have cancer occurrence data of local resident until now. The aim of this analysis is to know characteristics and data of cancer patients occurrence in Ulleung island for 10 years. Methods: We are offered data of cancer patients occurrence in Ulleung island for 10 years from National Cancer Center. This data was composed of sex, address (only town level), diagnosed date, diagnosis. So, we analyze this data and compare to Korea data for same duration. Results: There were 268 patients for 10 years (1993-2002). Man were 175 about 65% and women were 93 about 35%. There were 163 in Ulleungeup about 60%, 39 in Seomyun about 14.5% and 48 in Bukmyun about 18%. There were 19 patients in unknown residence. After 1998, above 30 patients were occurred, but before 1998, below 27 patients were occurred. Diagnosed date was concentrated in June, 33 patients were occurred about 12%, but least occurred month was December. Most occurred age were from 60 to 69, there were 80 patients about 30%. Most occurred cancer was gastric cancer, there were 54 patients about 20%. Hepatic cancer was second and third was lung cancer. In man, most occurred cancers were gastric cancer and hepatic cancer, both was 38 patients. In woman, gastric cancer and uterine cervix cancer were occurred mostly. After 2001, in Korea most occurred female cancer was breast, but in Ulleung island, most occurred cancer was stomach. Conclusions: Researcher should demand and analyze cancer data from National Cancer Center that cancer management project in local county and public health education of cancer could focus on local resident because annually released cancer data from National Cancer Center focus on a nation. In Ulleung island, cancer incidence was more than incidence in Korea and breast cancer was occurred less than in Korea. So, more study should be needed to confirm why more cancer were occurred than Korea and breast cancer was less occurred.

  • A merged altimeter data products are used to estimate sea level variation in the East Sea between 1993 and 2006. The altimeter data show a high correlation coefficient (0.85) after applying gaussian low pass filter for 180days at Ulleung island. The both of Mukho coast and Ulleung island are minimal sea level in March to May and maximal in September to November. Sea level of Mukho coast is higher than that of Ulleung island during March to May, while Mukho coast is lower during September to November because the North Korea Cold Current flows along the coast line of Mukho. Generally sea level variation at Mukho coast and Ulleung island associated with seasonal variations.
