The purpose of this study was to (md out the characteristics of the residential house in Ulleung Island in terms of building materials, structure and construction method, structural design by actual field surveys. This study found several facts; First, the house was classified into the log house and mud-wall house according to building material for wall structure. The log house prevailed in the early days of the settlement in the island because of affulent timber materials available around. However, the mud wall house became a popular type in later days because of the depletion of timber materials. Second, the Udeki wall was an unique installation reflecting the severe climate conditions of Ulleung Island. However, many aspects of the Udeki wall was changed according to the change of living style and the introduction of modem heating systems in terms of its function, size, building material, layout position etc. Third, the roofing material also has been changed from materials available locally to slate materials transported from the mainland. Fourth, the bamboo slender-ribbed door as a single-swing door type was popular and later time the single-sliding door or three ribbed door was widely used in rooms installed later instead. Fifth, the roof was placed over the room, kitchen, and Chukdam (outer wall) and this was a resonable way to cope with heavy snowfalls in the winter season in Ulleung Island.

울릉도의 피부 진균증 환자들은 타 지역에 비해 중복 감염율이 높은데, 이는 피부 진균증에 대한 환자들의 인식도가 낮기 때문으로 생각된다. 또한 가족 내 감염율도 타지역 보다 높아서 피부 진균증에 대한 예방 교육이 절실하다. 그러나, 피부 진균증 환자들의 나이가 고령화, 여성화 되고 있어 피부 진균증에 대한 인식을 높이기 위한 보건 교육을 고령 환자들과 여성 환자들에 맞추어 시행할 필요가 있다. 주위 동료들의 감염율도 높으므로 적절한 예방 교육이 이루어 진다면 피부 진균증의 예방 효과는 클 것으로 예상된다. 부족하나마 설문 조사로 피부 진균증 환자들의 피부 진균증에 대한 인식도가 미흡다는 사실은 울릉군 지역의 피부 진균증 예방교육의 필요성을 제시 할 것으로 생각된다. 추후에도 울릉군 지역의 피부 진균증에 대한 여러 가지 방면에서의 연구가 필요할 것으로 생각되며, 인식도 조사도 많은 환자와 주민을 대상으로 시행하여 통계적인 유의성을 찾아야 할 것으로 생각된다.

본 연구는 울릉도 현포항을 대상으로 지속가능한 공간환경 재생을 위한 새로운 패러다임으로서 지역주민, 중앙과 지방정부의 거버넌스에 기초한 어항개발방안을 모색하였다. 연구목적을 수행하기 위해 울릉도 주민을 대상으로 설문조사를 실시한 결과 첫째, 현재 울릉도 주거환경의 가장 큰 문제로 접근성 불량, 병원 보건소, 상가 부족 등 생활환경 취약이 높게 지적되었고, 둘째, 현재 정부와 지방자치단체의 울릉도 관련 개발 사업이 실제로 지역경제 활성화 및 울릉도 주민의 삶의 질 개선에 기여하지 못한다는 인식이 많았고, 셋째, 울릉도 관련 개발사업 추진의 애로사항으로 울릉도가 보유하고 있는 각종 자원에 대한 중요성이나 활용에 대한 인식 부족, 중앙정부와 지방자치단체의 지원 부족을 큰 문제로 지적하였고, 넷째, 현재 현포항의 관리수준을 미흡하게 인식하였다. 이상의 조사결과를 바탕으로 개발주체의 지속성, 현포항 개발의 비전제시, 주인의식 전환을 위한 노력, 지역현실을 고려한 단계적 추진, 거대한 테마보다 소규모로 알찬 콘텐츠를 제공할 수 있는 개발이 중요함을 보여주었다.

As a part of the on-going effort to conserve endangered Scrophularia takesimensis Nakai in Korea, its genetic structure and diversity from 3 population, consisted of 14 subpopulations in Ulleung Island were analyzed using RAPD band patterns. Out of 60 primers tested, 33 generated amplified bands with its genome, including 149 polymorphic and 67 monomorphic bands. The highest number (146) was found in northern population, especially, 64 in HY subpopulation; the smallest (40) in eastern population. An examination of its genetic structure with AMOVA revealed that about 60% of all variations could be assigned to among subpopulations within populations. Population differentiation among populations and subpopulations is seriously going now because of habitat fragmentation due to human activities, such as road and small port construction. Although the habitats of S. takesimensis in Ulleung Island, Korea are disappeared at an alarming rate, significant levels of genetic variation still exist at species level, and population level, especially northern population. Therefore, three conservation strategies should be needed urgently; 1) preservation of populations as it stands, 2) establishment of recovery plan to connect population and subpopulations genetically, and 3) long-term monitoring.

Ulleung Island is a biodiversity hotspot in South Korea. During a survey of indigenous fungal species from Ulleung Island conducted from 2015 to 2016, we discovered 10 unrecorded macrofungi in Korea. These macrofungi were identified to the species level using morphological features and phylogenetic analysis based on the internal transcribed spacer region: Deconica phyllogena, Mycena zephirus, Phaeomarasmius proximans, Phlebia radiata, Pluteus semibulbosus, Postia alni, Resinicium pinicola, Scytinostroma portentosum, Tricholomopsis flammula, and Tyromyces kmetii. We also provide detailed morphological descriptions for these 10 species.

The genetic diversity plays a significant role in determining a species' survival and perseverance. Endangered species often lack genetic variation, which makes them vulnerable to numerous dangers of extinction including selection, genetic drifts and human interference. Knowing an endangered species' genetic background greatly enhances conservation efforts since it reveals why, what and how to conserve that species. Cotoneaster wilsonii is an endangered plant species endemic to Ulleung island, but not enough genetic research has been done on this taxon for its effective conservation plans. In this study, three populations of C. wilsonii in Ulleung island underwent allozyme analysis through starch gel electrophoresis. 10 loci were analyzed and F-statistics was calculated. Overall data indicated that C. wilsonii possessed low genetic diversity with intense inbreeding, heterozygote deficiency and low differentiation among populations. These results implied that C. wilsonii was recently introduced to the Ulleung island from ancestor species, and did not have much time to differentiate. Current status of C. wilsonii habitats is very fragile and vulnerable, with increasing tourism constantly threatening the species' survival. It is very likely that C. wilsonii will become extinct in near future unless organized conservation protects its populations and genetic diversity.

화산지역에서 발생하는 라하르는 인명과 재산피해를 일으키는 주요 재해이다. 라하르 위험 지역을 산출하기 위하여 본 연구에서는 Laharz_py 프로그램을 사용하여 울릉도에서 발생 가능한 라하르의 영향 지역에 대한 수치모의를 실시하였다. 울릉도의 근위위험지역을 도출하기 위하여 DEM에 400 m의 추가고도를 설정하였고, 이에 따라 H/L비는 0.45와 0.5로 결정하였다. 발생 가능한 라하르의 부피는 30,000, 50,000, 70,000, $100,000m^3$로 설정하였다. 근위위험지역 경계와 인접하여 라하르의 발생 가능성이 있는 하천은 울릉도 동쪽 저동천, 남동쪽 사동천과 옥천천, 남서쪽의 남양천, 북쪽의 용출수인 추산천이며, 집중호우시 나리 분지에서의 라하르 발생 가능성도 고려하여 수치모의를 실시하였다. 본 연구는 울릉도에서 발생 가능한 라하르의 영향 범위에 대한 예측을 통해 화산재해로 인한 인명과 재산 피해를 줄일 수 있도록 재해위험지도를 작성하기 위한 기본 자료로 활용 가능할 것이다.

This study investigated the hydrogeochemical and microbiological characteristics of freshwater on Ulleung Island, a volcanic island in the Ulleung Basin on the East Coast of Korea. The shallow groundwater (CSW, NRGW) and the surface water (SISW) samples are classified as Na-HCO₃ type, reflecting an alkaline rock type and an oxidizing environment due to the influence of a highly permeable pyroclastic rock layer. In contrast, the deep groundwater sample (DMW) is classified as Ca-HCO₃ type, suggesting the influence of deep-sourced carbon dioxide and reducing conditions. Microbial communities in the water samples are generally dominated by Proteobacteria, with the relative abundance of major genera varying depending on water quality and environmental conditions. Network analysis reveals the ecological characteristics of microbial communities adapted to specific environments. The presence of pathogenic genera in the shallow groundwater suggests potential groundwater contamination, necessitating appropriate management to ensure its use as drinking water or domestic water. The findings of this study provide valuable insights into the ecological characteristics of Ulleung Island's groundwater resources and can inform future groundwater management strategies.
