  • 개인의 여가시간과 소득수준이 높아짐에 따라 해양 레저스포츠 활동이 활발히 진행되고 있으며, 그중 스쿠버 다이빙에 대한 관심과 참여도 계속 늘어나고 있는 추세이다. 하지만 스쿠버 다이빙은 물속에서 이루어지는 운동이므로 움직임에 제약이 크고 생명의 위험성이 높다. 이런 문제점을 해결하기 위해 가상으로 스쿠버 다이빙을 체험해 볼 수 있는 시뮬레이터가 필요하지만 이를 위한 체감형 수중 인터페이스에 대한 연구는 많이 부족한 실정이다. 본 논문에서는 스쿠버 다이빙 시뮬레이터를 제작하기 위해 해저 가상공간과 스쿠버 다이빙을 하드웨어 장비의 상호작용 인터페이스를 설계하였다. 제안방법은 스쿠버 다이빙에 사용되는 실제장비를 가상현실 시스템에 연동시킴으로서 체감형 스쿠버 다이빙 시뮬레이터의 현실감을 높일 수 있을 것이다.

  • Two specimens of Apogon cookii of the family Apogonidae were collected from the coastal waters of Dokdo, Korea, and described as the first record from Korea. Specimens were caught by SCUBA diving using scoop net (length 33 cm, depth 63 cm) on October, 1997. The species differs from A. endekataenia in having 5 longitudinal stripes and a small black spot on the base of caudal fin. The new Korean name, "Da-seot-jul-eol-ge-bi-neul" as new Korean name of Apogon cookii.

  • Two new marine sponges, Halichondria jangseungenesis n. sp. and H. nagokenesis n. sp., of the family Halichondriidae, were collected from Uljin-gun, Gyeongsangbuk-do, Korea by SCUBA diving during the period from Apr 2007 to Aug 2007. Based on their spicule composition and skeletal structure, H. jangseungenesis n. sp. appears to have a close similarity with H. panicea (Pallas, 1766); however, they differ in length of spicule. The spicule length of oxea of H. jangseungenesis n. sp. is shorter than that of H. panicea. Based on their spicule composition and growth form, H. nagokenesis n. sp. is quite similar to H. cylindrata Tanita and Hoshino, 1989; however, but they differ in length of spicule. The spicule length of oxea of H. nagokenesis n. sp. is longer than that of H. cylindrata.

  • A polynoid polychaete, Iphione muricata (Savigny, 1818), is newly recorded in Korean fauna. Genus Iphione was found for the first time in Korean waters. The specimen was collected in the Phyllospadix japonica bed by SCUBA diving. The species is described with figures and the key to subfamily was revised, Including this Iphione muricata, a total of 24 species representing 14 genera are known to the Korean polynoid polychaetes.

  • Colonial ascidians, Clavelina elegans (Oka, 1927) and Clavelina miniata Watanabe & Tokioka, 1973 are reported for the first time in Korean waters. As a result of this study, three species of the genus Clavelina are now recorded in Korean fauna. Clavelina elegans and C. miniata have been reported only from Japan. We expanded the distribution range of these species to Korea. The specimens of C. elegans and C. miniata were collected from the subtidal zone of Beomseom and Chagwido in Jeju-do by SCUBA diving. Detailed descriptions, illustrations and photographs of these species are provided in this paper.

  • A new marine sponge in the family Ancorinidae, Penares hongdoensis n. sp. was collected from Hongdo Island, Korea by SCUBA diving in 2004. P. hongdoensis n. sp. is closely related to P. cortius de Laubenfels, 1930 in their spicules. However, they differ in kind and size of spicules and growth form. The dichotriaene rhabds of new species are larger than that of P. cortius. And the new species has oxyaster, but P. cortius has oxyspheraster. Although the growth forms of both species are irregular massive, this new species shows conspicuous long projection toward upper part.

  • Some hydromedusae were collected from Gijang (Busan), Yeounggwang, Munseom (Jejudo Is.) and Shinhangman with Issacc-Kidd Midwater trawl net or by SCUBA diving from 2001 to 2003. They were identified into five species of five families in three orders and are new to the Korean fauna. Bougainvillia ramosa (van Benenden, 1844) of the family Bougainvilliidae in the order Anthomedusae, Phialidium hemishaericum (Linne, 1767) of the family Campanulariidae and Aeguorea macrodactyla of the family Aequoreidae in the order Leptomedusae, Diphyes dispar (Chamisso and Eysenhardt, 1821) of the family Diphydae and Abylopsis tetragona (Otto, 1823) of the family Abylidae in the order Siphonophora. With a result of this work, the Korean hydromedusa fauna consists of 31 species of 18 families in six orders.

  • Two new marine sponges in family Halichondriidae, Halichondria ulleungensis n. sp. and H. hongdoenesis n. sp. are collected from Ulleungdo Island and Hongdo Island, Korea by SCUBA diving during 2003-2004. H. ulleungensis n. sp. is similar to H. corrugata Diaz, Pomponi and van Soest, 1993 in the type of spicule, but it is different in growth form and choanosomal skeleton. The growth form is encrusting, with numerous erected cylindrical tube, comparing with massive-lobate of H. corrugata. The choanosomal skeleton is confused with loosely arranged oxea tract, comparing with densely tracts with many spicules of H. corrugata. H. hongdoenesis n. sp. is similar to H. surrubicunda Hoshino, 1981 in type of spicule and growth form, but this species has two kinds (thick and thin) of oxea.

  • Specimens of nudibranchs have been surveyed by scuba diving from 9 localities along the Korean coast. By examination of morphological characteristics, four species in the superfamily Doridoidea which are new to Korea were identified, and re-described: Thorunna florens (Baba, 1949), Diaulula sandiegensis (Cooper, 1863), Jorunna parva (Baba, 1938), and Doris odhneri (MacFarland, 1966). In addition, radulae of three species were observed and photographed by using scanning electron microscopy. As a result of the study, 16 species of doridoidean nudibranch are now known from Korean waters.

  • Shrimp of the family Stenopodidae occurr in tropical, subtropical and warm temperate parts of the world. Thirty-seven species of four genera (Juxtastenopus, Odontozona, Richardina, and Stenopus) of the family Stenopodidae have been reported in the world. Among them, only Stenopus hispidus of the family Stenopodidae has been recorded from Korean waters. The stenopodid shrimp, Odontozona arbur is reported for the first time from Korea. During a taxonomic survey of the deacapod crustaceans in Korean waters, O. arbur was collected by scuba diving in approximately 14 m depth from the Munseom Islet, in Jejudo Island on 28 Jun 2018. Odontozona arbur is the second species of the family Stenopodidae in Korea. It is easily distinguished from other species of this family in Korea by the entire dorsal surface of the abdominal somites. The morphology of this species is described and illustrated herein.
