The present study summarizes the occurrence, distribution and autecology of 12 taxa of the class Cyanophyceae collected from several swamps, reservoir and highland wetlands in South Korea from 2009 to 2012. A new species, Anabaena koreana sp. nov. and 11 taxa of blue-green algae newly recorded are described and illustrated. Anabaena koreana is similar to A. oumiana, A. spiroides and A. crassa in that the trichomes form regular coils. However, A. koreana is distinguished from these three species by the morphological characteristics of the vegetative cell, heterocyst, and akinet shape and size. This study considers 12 blue-green algal species, including a new species, Anabaena koreana sp. nov. and 11 species that are recorded for the first time in the Korean freshwater algal flora. Among them, the genus Nostochopsis Wood ex Bornet et Flahault 1886 had not previously been recorded in Korea.

Coccoid green algae collected from March to November 2015 from 79 freshwater ecosystem sites throughout South Korea, including lakes, ponds, swamps, streams, and rivers, were identified using light microscopy. A total of 218 taxa were identified, among which 11 were new species records in Korea; these 11 species were found at four sites (Hanagang River, Chukdong reservoir, Chukdong fishery, and Deokjin reservoir). The new species recorded were Fotterella tetrachlorelloides, Trochiscia naumannii, Keriochlamys styriaca, Placosphaera opaca, Siderocystopsis fusca, Siderocelis oblonga, Siderocelis estheriana, Pachycladella umbrina, Pachycladella zatoriensis, Crucigenia mucronata and Scenedesmus sempervirens.

The study evaluated the influence of feeding different maturity leaves i.e., tender, medium, coarse and mixed leaves of three different maturity during late larval stages of new bivoltine race $(CSR_{3} {\times} CSR_{6})$. The data were compared with shoot feeding and control batches in which conventional feeding method was followed. The most of the larval and cocoon characters were recorded significantly higher in tender leaves fed batches followed by T4 batch (2 times tender and 1 time coarse leaves). Lowest melting percentage (1.494%) was recorded in T4 and highest (4.69%) was recorded in coarse leaf (T3) fed batches. Significantly higher post cocoon parameters viz., average filament length, non-breakable filament length, renditta and raw silk percentage were recorded in tender loaves fed batches.

Two newly recorded carnivorous amphipod species, Anonyx gurjanovai Steele, 1986 and A. nugax (Phipps, 1774) belonging to the family Uristidae Hurley, 1963, were collected from the East Sea, Korea. Anonyx gurjanovai is included in the A. laticoxae group and is characterized by a concave palm of the propodus in gnathopod 1 and small posteroventral projection at epimeron 3. The other species, A. nugax, represents the A. nugax group and is distinguished from congeneric species based on the presence of a shorter and less acute projection on epimeron 3. There are 13 species of the A. nugax group recorded worldwide, but this is the first report on the presence of the A. nugax group in Korean waters. Previously, three species of the genus Anonyx had been reported in Korea, and through this study, we have added two newly recorded species. Both the newly recorded Anonyx species are illustrated and compared with the related species. A key to the Anonyx species in Korea is also provided.

Objectives : The purpose of this study was to analyze and identify the problems of the changes in regulations that are relevant to approval, notification, and review of herbal medicinal preparations and crude drug preparations. Methods : I collected the regulations of approval, notification, and review of medicinal products mostly from official gazettes, analyzed enactment and amendments regarding herbal medicinal preparations and crude drug preparations, and studied it from the view point of Korean medicine field. Results : Regulations in regards to approval, notification, and review of herbal medicinal preparations and crude drug preparations were first established in 1978. Herbal drugs started to be categorized as crude drug preparations in 1981 and the regulatory outlines were completed in 1999. From 2008 to 2012, the regulatory standards that let crude drug preparations be new drugs from natural products were established. Through those procedures, the followings became crude drug preparations: 1) wholly new prescriptions that are not recorded in Korean Medical Classics, 2) prescriptions that are recorded in Korean Medical classics but prepared with new standard, composition and efficacy, 3) prescriptions that are recorded in Korean Medical classics but prepared with new formulation, and 4) herbal drugs. In case of herbal medicinal preparations, however, only regulations that are related to 1) drugs prepared with new compositions that are not recorded in Korean Medical Classics, 2) drugs with same prescription and same formulation, and 3) drugs with new formulation were arranged. Conclusions : Actual circumstances on crude drug-oriented regulations regarding approval, notification and review and future forms of prescription and drug administration in Korean Medical Institutions can be expected due to expansion in range of herbal medicinal preparations and shrink in that of on-site preparations. Reasonable improvement in efficient usage of modernized herbal medicinal preparations in Korean medical institutions and prospective cooperation from related pharmaceutical industry are needed.

The characteristics of insect communities in specific localities reflect climatic and environmental status and change. We investigated the description pattern of new insect species by reviewing announcements of new or newly recorded insects in Korea published in five systematic journals between 1999 and 2009: Entomological Research (1999-2009), Insect Koreana (1999-2003), Journal of Asia-Pacific Entomology (1999-2009), Korean Journal of Applied Entomology (1999-2009), and Korean Journal of Systematic Zoology (1999-2009). A total of 757 new species were reported in 299 research papers. More than 85% of the newly described or reported species belonged to four orders: Coleoptera (225 species), Lepidoptera (202 species), Hymenoptera (141 species), and Diptera (82 species). The number of new species fluctuated from year to year, and a few major authors described most species. The graph of the cumulative number of species described in Korea was not asymptotic. We also examined the decadal trends in the proportion of species according to their biogeographical origin. The numbers of northern (Palearctic and Nearctic) and southern (Oriental) species recorded in Korea between 1999 and 2009 were increasing mainly due to the recent taxonomic research environment. It is also possible that recent climatic change induces new migrants toKorea from more southern parts of Oriental region, but more information is needed to confirm this hypothesis.

Hypsicera has been reported six species from South Korea. In this study, we reviewed 13 species of South Korean Hypsicera including seven newly recorded species from South Korea. Female of H. brevicornis and H. nigribasis are reported for the first time from South Korea since first record. Additionally, H. incarinata and H. yoshimoboi are reported new to China. We provide diagnoses of six newly recorded species and descriptions of two new females. We also provide photographs of key characters of seven newly recorded species and a key to 13 species of South Korean Hypsicera.
