Description and identifications of 6 species belonging to genus Phintella from Korea are in insufficient and inaccurate situation. In the present paper, redescriptions illustrations and identification key are provided for 7 species of genus Phintella including P. popovi newly recorded in Korean spider fauna, and Ocius munitus described by Wesolowska (1981s) was synonymized to P.cavaleriei. For the author's identiication and pairing to be valid multivariate analysis was performed with 13 RVCs below STD 0.05 to 134 individuals. The result of discriminant analysis carried out with 13 RVCs of 134 individuals was not satisfactory, but cluster analysis performed with mean ratio values of 14 OTUs to 13 RVCs showed the same result with author's pairing except P.abnormis , which has larger dissimilarity than the pairs of the others. So pairing of 7 species was possible as a whole because one species only failed in pairing , even though this is imperful result. This method to be helpful to pairing test and identification if it were to improve.

The ascidians specimens were collected from Tangsa and its adjacent waters in Korea by scuba divers during the period from 1994 to 1999. They were identified into 30 species which are reported for the first time in Tangsa. Out of them one species, Molgula hozawai, was turned out to be new to the Korean fauna, and six species, such as Eudistoma illotum, Symplegma connectans, Boltenia trasversaria, Microcosmus nultitentaculatus, Pyura squamata and Molgula hozawai, were newly recorded in Chundo Island and Geojedo Island, which are influenced by warm waters of the Kuroshio Current.

A taxonomic study on the marine sponges was conducted with materials which were collected from Ulleung Island and Chuja Island, Korea by SCUBA diving during the period of July 2000 to May 2005. Among them, two species, Mycale (Aegogropila) jukdoensis n. sp. and Mycale (Mycale) chujaensis n. sp. are new to science. M. (A.) jukdoensis n. sp. seems closely to M. grandis based on the shape of spicules, but our new species has two categories of subtylostyles and also larger sigmas and raphides than those of M. grandis. And anisochelae I of M. (A.) jukdoensis n. sp. is smaller than that of M. grandis. M. (M.) chujaensis n. sp. is similar to M. sulgata in the growth form and size of microscleres. However, the new species has two categories of subtylostyles instead of one type in M. sulgata.

The life history of Obelia bicuspidata Clarke, 1975 (Hydrozoa, Campanulariidae) was studied in its habitats, Jak-yk Island, Korea and in the laboratory It grows mainly attaching to the under sides of small rocks immersed in muddy shores, or the shade surfaces of oyster shells. The hydoids liberate medusae. The medusa buds develope twice per year, during from March to June and from September to October The optimum water temperature for the hydroids is between 4$^{\circ}C$ and 8$^{\circ}C$ and at the temperature above 9$^{\circ}C$ the hydroids begin to degenerate. In August the surface water temperature is around $25^{\circ}C$ and the hydrothecae are all disappeared. The hydroids grow best during from February to May. The medusae are small, 0.3 mm high, 0.45 mm wide and require about 9 days at room temperature (about 2$0^{\circ}C$) for mature after releasing. Obelia bicuspidata turned out to be boreal species in this work.

Two stichotrichid ciliates, collected from marine waters in Jeju Island, were identified as Afroamphisiella multinucleata Foissner et al., 2002 and Pseudokahliella marina (Foissner et al., 1982) Berger et al., 1985. They are recorded for the first time in Korea. The descriptions are based on examinations of living as well as protargol-impregnated specimens. These species are characterized as follows. Afroamphisiella multinucleata has a body size in vivo of $70-95{\times}20-35{\mu}m$; elongate rectangular in shape; contractile vacuole located slightly above mid-body. The adoral zone is bipartited into 3 distal and 13-17 proximal membranelles and occupies 28-35% of the body length. The frontal row comprises 1-4 cirri and one buccal cirrus. The amphisiellid median cirral row is composed of 14-21 cirri, 10-19 left marginal cirri, and 21-30 right marginal cirri. Cortical granules are yellowish. 11-20 globular/ellipsoidal macronuclear nodules arrange proximally along the cell margins. Pseudokahliella marina has a body size in vivo of $110-195{\times}40-110{\mu}m$ and broadly elliptical in shape. The adoral zone of the membranelles occupies 50-60% of the body length, and is composed of 41-70 membranelles. A prominent frontal scutum is present. The contractile vacuole is located below the mid-body. There are 11-13 frontoventral rows, including marginal rows. Caudal cirri and transverse cirri are absent. Three invariable non-fragmented bipolar dorsal kineties are present. The left and right marginal rows are composed of 22-35 and 28-40 cirri, respectively. Colourless cortical granules are present. 8-11 spherical/ellipsoidal macronuclear nodules are connected with each other by thread-like tructures, forming an inverted C-shape.

Electrophoretic methods were used to examine the degree of genic variation and genetic relatedness in 11 populations representing 6 species and subspecies of the genus Parus in Korea. The average degree of genic variation of 3 subspecies of P. major was =1.2, =24.4% , D=0.042, and G=0.058, whereas the rest of the species showed slightly lower degree of genic variation than P. major. Genetic relatedness between subspecies and species in the genus Parus showed similar to those reported at comparable taxnonomic levels in other birds. But it appears to be considerably less than that of non avian taxa. Genetic relatedness between 3 subspecies of P.major and P. varius varius was closely related(=0.80), whereas between P.palustrius hellmayri and P.ater amurensis was relatively remote (=0.67). The presumed divergent times of P.palustrius hellmayri, P, ater amurensis , and P. varius varius were about 1.8, 1.6, and 1.0million years before present respectively, and 3 subspecies of P. major were recently differentiated about 100 thousands years before present.

Two hypotrich ciliates, Australocirrus shii (Shi et al., 1997) Kumar & Foissner, 2015 and Afrokeronopsis aurea (Foissner & Stoeck, 2008) Foissner et al., 2010 isolated from freshwater habitats in Korea and were studied based on the specimens from live and after protargol impregnation. Australocirrus shii is redescribed based on morphology and 18S rRNA gene sequence, whereas Af. aurea is the first record for Korea. Main morphological features of the Korean population of Au. shii are as following: body size $100-200{\times}40-80{\mu}m$ in vivo; elongate to ellipsoidal or slightly elongate obovate, dorsoventrally flattened; transverse cirri arranged in (3+2) pattern, anterior pretransverse ventral cirrus distantly anterior of the first transverse cirrus; eight or nine dorsal kineties; and three caudal cirri. Main morphological features of the Korean population of Af. aurea are as following: body size $230-375{\times}70-145{\mu}m$ in vivo; shape elongate obovate or ellipsoidal, widest at the mid-body; undulating membranes in Australocirrus pattern with a buccal depression; and three caudal cirri. The Korean population of A. shii is similar in morphology with previous descriptions except for the presence of indentation at the posterior end in the Korean population. The Korean population of A. aurea is slightly shorter than the South African population and has slightly less marginal and mid-ventral cirri. The phylogenetic analysis of present two Korean hypotrichs and relevant species based on 18S rRNA gene sequences generated almost similar tree topologies compared with previous studies.

Hangeul is growing as cultural icon representing Korea. And Hangeul is scientific and is too systematics for words as the guide of modern design. First it can make the variable and beautiful foams like dot, line and plane. It also has the basic design principles like symmetry and repetition. The purpose of this study is to develop textile designs using the formative characteristics of Hangeul. So in this study it was chosen 'ㄱ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅍ' of Hangeul's consonants and 'ㅑ, ㅕ' of Hangeul's vowels as the subject materials of textile designs development to develop textile designs expressed the geometrical shapes and formative beauty of Hangeul. Those are designed by using a variety of motifs that recast the shapes of Hangeul. So six textile designs for necktie and scarf were developed. Through this study it will be offered to the possibility of products that was based on Hangeul.

A scientific name is one of changeable terms in biology whenever additional research results of specific taxa is accumulated. The Database of the National Species List of Korea (DBNKo) was developed to manage taxonomic information of Korean species, designed to describe the changeable and complex taxonomical structure and information. A Korean Taxonomical Serial Number (KTSN) was assigned to each taxon, different from the normally used systems that the scientific name was considered as primary key to manage higher rank of taxa systematically. Common names were also treated with the KTSN, reflecting that common name is considered as one type of taxon. Additional taxonomic information (e.g., synonyms, original names, and references) was also added to the database. A web interface with an intuitive dashboard presenting taxonomic hierarchical structure is provided to experts and/or managers of the DBNKo. Currently, several biological databases are available in the National Institute of Biological Resources (NIBR) such as a specimen database, a digital library, a genetic information system, and the shared species data based on the DBNKo. The DBNKo started sharing species information with other institutions such as the Nakdonggang National Institute of Biological Resources. It is an ideal centralized species database to manage standardized information of Korean species.
