본 연구에서는 기능성 식품인 오미자의 이용 확대를 위해 오미자 분말 1.5, 3, 4.5, 6% 첨가한 스펀지케이크를 제조하여 반죽의 비중, 점도, 스펀지케이크의 수분함량, 일반성분, 색도, 부피지수, 무게, texture, 관능검사 결과를 실시하였다. 스펀지케이크 반죽 점도는 대조군과 1.5% 첨가군이 유사한 값을 나타내었고 나머지 첨가군들은 유의적으로 감소하였다. 비중은 대조군이 0.41이었고 오미자 분말 첨가군들 사이에 유의적인 차이를 나타내지 않았다. 케이크의 수분함량과 무게는 대조군과 첨가군들 간에 유의적인 차이를 나타내지 않았다. 케이크의 외부와 내부 색도를 측정한 결과 외부의 L(명도), 녹색도, 황색도는 오미자 분말 첨가량이 증가할수록 유의적으로 감소하였으며, 내부 L(명도)과 황색도는 첨가량이 증가할수록 유의적으로 감소하였으나 녹색도는 오미자 분말 첨가량이 증가할수록 유의적으로 감소하였다. 조직감 측정 시 hardness는 유의적 차이가 나타나지 않았으며, 소비자 검사에서 부드러움은 4.5% 첨가군까지는 5점 이상의 점수를 나타내었다. Fracturability는 대조군과 오미자 분말 첨가군들 사이에 유의적인 차이를 나타내지 않았으며, resilience는 오미자 분말 첨가량이 증가할수록 유의적으로 높게 나타났다. 관능평가는 케이크의 색과 부드러움, 향미, 전체적인 기호도는 오미자 분말 3% 첨가군까지 보통 이상의 점수를 나타내었다. 위의 결과를 고려하여 오미자 분말을 첨가한 스펀지케이크 제조 시 오미자 분말을 1.5~3% 첨가하는 것이 적절한 배합비로 사료된다.

A new marine sponge in the family Microcionidae, Ophlitaspongia yongjeongensis n. sp. is collected from Yongjeong-ri, Hyeongyeong-myeon, Muan-gun, Korea during 2005-2007. O. yongjeongensis n. sp. is closely related to O. reticulata in growth form (shape and color). However, the thick style and slender style of O. yongjeongensis n. sp. are larger than O. reticulata's (Bergquist and Fromont, 1988).

A new marine sponge in the family Tethyidae, Tethya uljinensis n. sp. was collected from Uljin, Korea in 2007. Halicometes koreana in the family Tethyidae was redescribed. Tethya uljiensis n. sp. is closely to Tethya simi. in skeletal structure and spicule composition. But, it differs in the size of spicules(stronyloxea) and shape of oxyaster.

Galactosyl ceramides paly important roles in biological system as immunomodulator and essential constituents of membranes and cell walls. An efficient synthesis of $\alpha$-galactosyl ceramide, KRN 7000, derived from marine sponge Agelas mauritianus as accomplished via a short reaction involving the coupling ceramide moiety and trichloroacetimidate as glycosylation donor. We could synthesize $\alpha$-galactosyl ceramide stereoselectivity without $\beta$-anomer formation on a multigram scale.

Sesquiterpene-quinone is a class of secondary metabolites frequently encountered from marine sponge. The present study was designed to examine the anti-inflammatory action of sponge-derived dactyloquinone B (DQB) and cyclospongiaquinone-1 (CSQ1) mixture using lipopolysaccharide (LPS)-induced inflammatory responses. We measured the production of nitric oxide (NO), tumor necrosis factor-alpha ($TNF-{\alpha}$), $interleukin-1{\beta}$ ($IL-1{\beta}$), and interleukin-6 (IL-6) and expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) protein. $TNF-{\alpha}$, $IL-1{\beta}$, and IL-6 production, which increased by treatment with LPS, were significantly inhibited by DQB and CSQ1 mixture. It also decreased the production of NO production, and iNOS and COX-2 expression. Furthermore, it reduced 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced ear edema of ICR mice. These results demonstrate that sesquiterpene-quinone, DQB and CSQ1 mixture, might serve as a chemical pipeline for the development of anti-inflammatory agent.

The continuous exploration in deep seawater from Korea makes us lead the discovery of ancient Chlorophyta, Palmophyllum, in the Korean coast. The phylogenetic analyses of 18S rRNA and rbcL genes demonstrate that our specimens are Palmophyllum crassum (Naccari) Rabenhorst, recorded in Japan and clearly distinguished from P. umbracola from New Zealand and California, USA. Palmophyllum crassum grows in the subtidal region, 8-30 m deep, and has a crustose thallus which is closely adherent to substrates such as non-geniculate crustose coralline algae, sponge, shells, or rocks. P. crassum is composed of numerous spherical cells embedded in the gelatinous matrix. The discovery of this ancient green seaweed implies that the Korean coast is one of the hotspots of algal species diversity and has the suitable marine environment for algal speciation. We suggest the grounds to conserve the Korean coast environmentally as the biodiversity center of marine species by studying the phylogeny of seaweeds.

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 study on marine sponges was conducted by SCUBA diving at Ulleungdo Island, Korea, from July 2001 to August 2003. Two species, Mycale (Naviculina) ulleugensis and Mycale (N.) neunggulensis, are new to science. Mycale (N.) ulleugensis n. sp. seems close to M. chungae based on the shape of spicules, but differs in the size of megascleres and sigmas, Mycale (N.) neunggulensis n. sp. seems close to M. flagellifer Vacelet and Vasseur in the type and size of spicules, but differs in the shape of naviculichela. Naviculichela I of M. flagellifer has a spine on the upper part of the felix.
