Thirty three entomopathogenic species belonging to twelve genus were collected throughout 16 collecting sites from 1990 to 1996. Among those collected species, 14 unrecorded species such as Cordyceps bifusispora, C. martialis, C. oxycephala, C. paludosa, C. pentatomi, C. rosea, C. ryogamiensis, Shimizuomyces paradoxa, Akanthomyces aculeatus, Polycephalomyces ramosus, Tilachlidiopsis nigra were added to Korean entomopathogenic species through this study. In nature, occurrence of Cordyceps nutans, C. sphecocephala and Paecilomyces tenuipes were from early June to late September. On the other hand, C. militaris, C. kyushuensis and C. pruinosa were mainly found from mid July to mid August when relative humidity are increased. Nine species of the genus Cordyceps including C. bifusispora and four deuteromycetous species were isolated. As a result of cultural test using six Cordyceps species, anamorph of C. militaris, C. kyushuensis were proved as Verticillium sp. C. pruinosa as Acremonium sp., C. sphecocephala as Hymenostilbe sp. and C. scarabaeicola as Beauveria sp., respectively.

The results of survey on the nematodes associated with sapling from 8 Forestry Experiment Stations(F.E.S.) in Korea are reported herein. A total of 35 species under 20 genera, 11 families, and 2 orders were identified from the soils around the roots of 119 tree species and amongst them, Xiphinema insigne is unrecorded species for Korea and Geocenamus sp. is a new species. Tylenchorhynchus claytoni, which showed the highest detection rate (D.R.) from all F.E.S., except Nambu F.E.S, was the dominant species among the nematodes associated with saplings. The D.R. of T. claytoni was the highest in Ch’ungnam F.E.S. by 100% from 15 saplings sampled, followed by 87.5% in Kangwon, 66.6% in Kyongbuk, 58.3% in Cheonbuk, 48.1% in Ch’ungbuk, 41.3% in Kyongki, and 40% in Cheonnam F.E.S. Other important nematode species which showed very high densities by stations are; Criconemella morgensis (D.R.: 37.5%), Helicotylenchus digonicus (D.R. : 35%), Pararotylenchus pini (D.R.: 37%), Tylenchorhynchus nudus (D.R.: 37.9%), Criconemella informis (D.R.: 27.5%), and Meloidogyne sp. (D.R.: 12.5), from Chunbuk, Chunnam, Ch’ungbuk, Kyongki, and Kangwon F.E.S., respectively.

Two naturalized plants belonging to Asteraceae (Compositae) were collected in Gangwon-do and Jeju-do. Euthamia graminifolia (L.) Nutt., a taxon of unrecorded genus Euthamia Nutt., was found in Inje-gun, Gangwon-do. This species can be distinguished from Solidago japonica Kitam. and S. gigantea Aiton by punctate, entire leaves and disc corollas without vein. Its Korean name was given 'Mi-yeok-chwi-a-jae-bi' because it shows similar external appearances with that of the Mi-yeok-chwi (Solidago japonica Kitam.). Gamochaeta pensylvanica (Willd.) Cabrera was discovered in Jeju-do. It can be distinguished from G. purpurea (L.) Cabrera by withering basal leaves at flowering and relatively short inner phyllaries. This taxon was named 'Mi-guk-pulsom- na-mul' in Korean by considering its specific epithet.

This study presents a survey on the bryophytes in Dongbaek-dongsan located at Seonheul Gotjawal on the north-eastern face of Mt. Halla in Jeju Island, Korea. A total of 85 taxa belonging to the Bryophyta (22 families 44 genera 62 species), Marchantiophyta (12 families 16 genera 23 species) were found. Among them, 3 moss species, Diphyscium perminutum Takaki, Racomitrium japonicum Dozy & Molk., and Isopterygium minutirameum (M$\ddot{u}$. Hal.) A. Jaeger. were new additions to the bryophyte flora of Korea. The liverwort index was 27.0%. Predominant life-form was weft. The rates for the bryophytes dominating in mesic to hygric sites were higher than for the bryophytes mainly observed in xeric habitats. We considered that the composition and distribution of species are affected by the different environmental factors according to the evergreen broad-leaved forests, wetlands and exposed spaces. Moreover, the rocks were the substrate type that play a major role in providing the micro-habitats for bryophytes in this area. Particularly, the bryophytes of swamps in this area were very unique and various for its limited space and showed plant communities with mosaic spatial pattern, along with vascular plants. We suggest more detailed and comprehensive studies on the swamps where endemic fern Mankyua chejuense B. -Y. Sun, M. H. Kim & C. H. Kim inhabits to provide valuable information for the conservation and restoration of the species and habitats.

HEMIRE is a 6,000-meter-class remotely operated vehicle (ROV) that has been developed for observation and sampling of objects of interest on the deep seabed. We first carried out deep-seabed exploration around the slopes of the Hupo Bank and the Ulleung Basin in the East Sea in June 2015. Over two weeks, a total of 10 dives were made from a support ship, the R/V Onnuri, at eight stations with water depth ranging between 194 and 2,080 m. The dive times ranged from 1 to 6 hours, depending on the operating conditions. We obtained the following results: 1) video images of the deep seafloor; 2) red snow crab density data (a major fishery resource) and inventories of deep-sea fauna, including an unrecorded organism; 3) specific topographies such as canyons slopes; 4) an undisturbed sediment core obtained using a push corer; and 5) observations of the seabed surface covered with discarded anthropogenic waste material.

The article has the characteristics of a preliminary writing about how to look at the trend of new archives 'fever' and 'impulsion' emerging around the domestic and foreign art world, which have not been paid much attention yet in the 'mainstream' archive research, and how to accept it independently. Specifically, this study aims to examine how archival art is involved in history and memory with aesthetic attitudes and methods through observation of recent tendency of domestic archive art, and what implications or influence the 'archival impulse' phenomenon in the art world can have on the research trend of 'archival studies.' First, I would like to look at the meaningful movement to reinterpret and actively accept archival impulses in concrete overseas cases, that is, the archive system of a public archive in the United States. This is followed by an attempt to explore the characteristics and characteristics of creative works that are carried out through the medium of archives, that has not yet reached the level of organization of specific archive methods but are sporadically attempted in the domestic art world. It examines how so-called 'archive artists' record unrecorded in a way that is not observed in the existing archival world, and how they summon and include excluded history in aesthetic language. In conclusion, this study explores the possibility of pulling the historical records of tradition out from archival boxes and reinterpreting them as living archives within the contemporary emotional structure from this new artistic trend called 'archival art'.

Two unrecorded naturalized species, Lolium rigidum Gaudin (Poaceae) and Oenothera rosea L'H$\acute{e}$r. ex Aiton (Onagraceae) were newly reported in Korea. L. rigidum, 'Daeng-Dol-Bo-Ri', was found at roadside of Yesong beach, Yesong-ri, Bogil-myeon, and roadside of Myeongsasimni beach, Sin-ri, Sinji-myeon, in Wando-gun, Jeollanam-do. It was distinguished from L. mutiflorum Lam by spikelet 10-20 mm long, florets 2-10(-13), and obtuse lemma, awn absent or up to 3-8(-10) mm. O. rosea, 'Ae-Ki-Bun-Hong-Nat-Dal-Mat-I-Kkot', was found in side of Wondong wetland, Yongdang-ri, Wondong-myeon, Yangsan-si, Gyeongsangnam-do. This taxon was distinguishable from other Oenothera in Korea by following combination of characters, stem erect to ascending, petal 5-12 mm long, pink to bright purple. Descriptions and illustrations of the two taxa and their photographs in the habitat are provided along with a key to the species of Lolium and Oenothera from Korea.

Since a new (unrecorded) species was reported in 2016, a total of four sea snake species are currently listed in Korean waters. Although the possibility of year-round inhabitation of sea snakes in Korean waters has increased due to climate change, the related studies are scarce because of the lack of human resources and available equipment. We placed posters and banners requesting voluntary information on sea snakes in coastal regions and Jeju Island to obtain information on sea snake distributions in the coasts of South Korea and possible specimens through volunteer activities. As a result, we received total 45 reliable reports, including photographs or video, between March 2013 and December 2016. Eighteen reports on three sea snake species and thirteen capture cases of two species were submitted from Jeju Island and southern coastal regions of Korea mostly between August and November. There were twenty-seven false reports including seven cases of terrestrial snakes, eighteen fishes, and one each of invertebrate and inanimate material. Based on the results, we proposed the effective way of sea snake surveys using volunteers.
