One of the largest genera of subfamily Ophioninae, Ophion, has been reported 144 species in the World. Nevertheless, recorded members of genus Ophion are 40 species in the Eastern Palaearctic region, 8 in South Korea (O. ainoicus, O. choaspese, O. flavopictus, O. fuscomaculatus, O. luteus luteus, O. obscuratus obscuratus, O. okunii, O. takaozanus). In this paper, a taxonomic list of genus Ophion from South Korea is provided for the first time. Two newly recorded species, Ophion hokkaidonis Uchida and Ophion nikkonis Uchida, are reported from South Korea. A key to these South Korean species, diagnoses of the two newly recorded species and digital images are provided.

Actiniarians were collected from the rocks and sand bed of Jejudo Island, Ulleungdo Island, and Wangdolcho in Korean waters from 2004 to 2009. They were classified as two species of two families belonging to the suborders Endocoelantheainea and Nynantheae. Especially, suborder Endocoelantheainea, with distinct development of mesenteries, was firstly added to Korean athenarian fauna with the species, Halcurias carlgreni McMurrich, 1901. Calliactis polypus (Forsk$\aa$l, 1775) showing the commensalism with hermit crab, was easily distinguished from C. japonica by external features and the composition of cnidae. These two species were described in detail with tables and figures.

The two zooxanthellate scleractinian corals are newly recorded in Korea: Psammocora albopicta Benzoni, 2006 of the family Psammocoridae and Oulastrea crispata (Lamarck, 1816) of the family Faviidae. These families are also newly recorded in Korea. Specimens were collected from the subtidal zones of Jeju-do Island, Korea by SCUBA diving from 1999 to 2014. Two scleractinians are described based on the morphological characters of skeletal structures. Psammocora albopicta is distinguished by its encrusting cerioid growth form, high density of corallites, small calicular diameter, single styliform columella, and fewer rows of enclosed septa. Oulastrea crispata is characterized by its encrusting plocoid growth form, polygonal calicular shape, irregular paliform lobes, and papillose columella.

Two cold water species of dendronotid nudibranchs are described for the first time in Korea: Dendronotus frondosus (Ascanius, 1774) and Dendronotus robilliardi Korshunova, Sanamyan, Zimina, Fletcher & Martynov, 2016. Dendronotus frondosus is characterized by the color pattern of deep dark-brown with white specks and mottles on the dorsum. Dendronotus robilliardi is distinguished by the body of translucent white with milky stripes and orange-brown markings in papillae, and D. robilliardi from Korean water is commonly examined with white dots on the anterior dorsum. Images of external morphology and brief re-descriptions of two species were provided. Further, we confirmed the opinion of Korshunova et al. that the Korean D. albus image by Koh would be D. robilliardi.

The Ulvophyceae are a diverse group and most species are distributed in marine environments, however, a smaller diversity occurs in freshwater and terrestrial habitats. Also, the diversity of species belonging to Ulvophyceae has been superficially investigated in Korea. Here, we identify two freshwater ulvophycean species based on the morphology, ultrastructural observation, and phylogenetic analysis. As a result, their taxonomic classifications are as follows: order Ulvales Blackman and Tansley, 1902 - family Kornmanniaceae Golden and Cole, 1986 - Lithotrichon pulchrum Darienko and Proschold 2017; order Ulotrichales Borzi, 1895 - family Tupiellaceae Skaloud and Leliaert, 2018 - Tupiella speciosa Darienko and Proschold 2017. The family Tupiellaceae and the two genera Lithotrichon and Tupiella are reported for the first time in Korea.

Recently, two energy-based response parameters, i.e., the absolute and the relative elastic input energy equivalent velocity, have been receiving a lot of research attention. Several studies, in fact, have demonstrated the potential of these intensity measures in the prediction of the seismic structural response. Although some ground motion prediction equations have been developed for these parameters, they only provide marginal distributions without information about the joint occurrence of the spectral values at different periods. In order to build new prediction models for the two equivalent velocities, a large set of ground motion records is used to calculate the correlation coefficients between the response spectral values corresponding to different periods and components of the ground motion. Then, functional forms adopted in models from the literature are calibrated to fit the obtained data. A new functional form is proposed to improve the predictions of the considered models from the literature. The components of the ground motion considered in this study are the two horizontal ones only. Potential uses of the proposed equations in addition to the prediction of the correlation coefficients of the equivalent velocity spectral values are shown, such as the prediction of derived intensity measures and the development of conditional mean spectra.

Background : To examine the difference between ICD-10 and The Korean standard classification of disease(oriental medicine), and to aim at improve the practical use as statistical data. It is one of the reason of disease classification. On that account we convert the many to many correspondence presenting classification of oriental medicine into many to one correspondence. Method : The study tracked out 155 patients discharged from the university hospital which is located in Gyeonggi Province and managing hospital and oriental medicine hospital from July to October this year. The period of this study was from August 1 to November 18. We compared correspondence between the two services' diagnosis(hospital services and oriental medicine hospital services) at the same time and attempted many to one correspondence classification. That is for production of statistical data. Result : We investigated the group which have had medical treatment experience of two kinds of services at the same time. The result of this investigation was that the same oriental medicine diagnosis used differently in western medicine diagnosis. 44.5% was accorded with western medicine diagnosis. Correspondence of the western medicine diagnose with the top of the Korean standard classification of disease(oriental medicine) list's western medicine diagnosis was 13.5%. For many to one correspondence classification for statistics, one western medicine diagnosis was selected for one oriental medicine diagnosis. In case of the main diagnosis(I sign) was not enough to explain oriental medicine diagnosis' characteristic, we chose multiple other diagnosis, so other diagnosis(II sign) about patient's cause of disease could be selected for supplement after we examined the patient's records. The statistics was possible with this many to one correspondence. Conclusion : The result of this study about correspondence between western medicine diagnoses and those of oriental medicine confirms that The Korean standard classification of disease(oriental medicine) is hard to be standardized with western medicine diagnosis. Therefore, according to this study, we use new many to one correspondence classification, multiple oriental medicine diagnoses with one ICD-10, which can be used by statistical data.

Candoninae is the most diverse group of freshwater ostracods with over 300 living species described from all around the world. However, only 11 species have been reported from South Korea. Considering abundant freshwater ecosystems here this number is very low. It is no wonder that newly collected samples of freshwater meiofauna often contain Candoninae ostracods which are new records for South Korea, or new taxa. Earicandona mounchyon gen. nov. sp. nov. and Typhlocypris (Pseudocandona) pratensis (Hartwig, 1901) were collected from two open freshwater bodies in Gangwon-do, and Gyeongsangbuk-do in South Korea. The new genus is most closely related to the breuili-group of Fabaeformiscandona Krstic, 1972. The most important apomorphic character of the new genus is a hemipenis with a poorly sclerified lobe "g", and prehensile palps with more rounded dorsal margins. Beside the new species, Earicandona contains only E. okuboi (Smith & Janz, 2008) comb. nov. from Lake Biwa. This species was originally described in Fabaeformiscandona, fabaeformis-group. They differ mostly in the morphology of the shell, but also some details of soft body, including the more pronounced genital process in the Korean species. Typhlocypris pratensis was so far known from Europe and this finding significantly broadens its area of distribution. Both Typhlocypris and Earicandona belong to the tribe Candonini and the key to the genera of this tribe is also presented here.
