This study was conducted from February 2005 to October 2007 to investigate bird distribution at three types of forest (mixed, broadleaf and coniferous) in Gwangneung forest. As a result, more birds used mixed forests than broodleaf and coniferous forest. During forest was opened to public, more birds also frequently used mixed forests. When forest was closed to public, there was no preference among three forest types. We also compared the number of species and individuals between open and restricted area. More species and individuals used restricted area.

방송에서는 당사자의 동의 없이 얼굴을 노출 시키거나, 유해물질로 판단되는 물체의 노출을 금지하고 있다. 기존의 처리방식으로 편집자가 촬영된 영상을 직접 편집하거나, 촬영 시 가리개를 이용하는 방법을 사용한다. 이러한 방법은 번거롭고, 실수로 인해 얼굴이나 유해물질이 방송에 그대로 노출될 수 있다. 본 논문에서는 딥러닝 기반의 객체탐지 모델과 동일인 판단 모델을 사용하여 편집 과정을 자동으로 처리하고 후처리뿐만 아니라 실시간 방송에서의 적용을 위해 추가적으로 객체추적 알고리즘을 도입하여 처리속도를 높이는 방안을 제시한다.

This study is to develop a Geotourism program focused on Taean Haebyeongil course 5 (coastal walkway) and to introduce an explanation board to revitalize an effective Geotourism program of the Taeanhaean National Park. Generally Geotourism program is developed by analyzing topography, geology and cultural resources of the Taean Haebyeongil course 5. An explanation board, which is revitalizing an effective Geotourism program can be used when explaining each trekking courses and providing information about observable geological features to the visitors. This study suggested a new method of explaining geological features and cultural resources to visitors of the Taeanhaean National Park. Additionally, developing a new program of Taean Haebyeongil, is believed to provide a diversity of locational contents to visitors. Hopefully this new program will boost the tourism business of Taean Haebyeongil.

Antitumor activity was tested by administration of reaction mixture of green onion extract and chitin to mice bearing sarcoma-180 cells. An intraperitoneal injection of mixture(20 mg/kg/day) to mice Have an 52% inhibition of tumor growth. Inhibition of tumor growth was found to be dose-dependent. When eighty miligrams of the mixture were administered, the weight of tumor was reduced significantly. HPLC analysis indicated the mixture was composed of N-acetyl-D-glucosamine, N-acetylchitobiose and N-acetylchitotriose.

The order Nudibranchia Cuvier, 1817 is among the most colorful gastropod group that lacks an external shell and mantle cavity at their adult stage. They are widely found in the intertidal to subtidal zones of marine habitats worldwide. To date, a total of 58 species are known from Korean waters. In this study, we report seven nudibranch species that are newly reported from Korean waters and provide their color images of external body, morphological description, taxonomic remarks, and mtDNA cox1 barcode sequence information: Dendronotus primorjensis Martynov, Sanamyan & Korshunova, 2015; Doto japonica Odhner, 1936; Trinchesia ornata (Baba, 1937); Antiopella fusca (O'Donoghue, 1924); Cadlina paninae Korshunova, Fletcher, Picton, Lundin, Kashio, N. Sanamyan, K. Sanamyan, Padula, Schrodi & Martynov, 2020; Rostanga bifurcata Rudman & Avern, 1989; and Goniodoridella savignyi Pruvot-Fol, 1933.

The objectives of this paper are to estimate home range and core habitat area of wild bores in Jirisan National Park of Korea. A radio-telemetry study was carried out on 5 wild boar individuals (3 females and 2 males). Except one individual whose enough data could not be collected, the mean home range size of 4 individuals was $5.13km^2$ (95% kernel) and mean core habitat area was $1.18{\pm}0.31km^2$ (50% kernel). Home-range sizes of 2 females were $6.21km^2\;and\;5.45km^2$ each, and that of 2 males were $5.15km^2\;and\;3.72km^2$ each, which means home-ranges of female boars were larger than those of male boars in this research. This result is presumed to have been caused by the fact that the males were sub adult individuals weighing 40 kg and 19 kg when they were captured for this research.
