Two species belonging to the genus Gregarinidra Barroso, 1949 (Bryozoa: Gymnolaemata: Flustridae) were first found in this study from Korean waters. Gregarinidra furcula n. sp. is new to science, and G. incrustans (Silén, 1941) is newly added to the Korean fauna. Species belonging to this genus are primarily distinguished by two characteristics: interzooidal avicularia and marginal spines. The pitchforked spines clearly distinguish G. furcula n. sp. from the other Gregarinidra species, and G. incrustans shows the difference by having blunt spines and short-triangular avicularia. Gregarinidra incrustans was known to be distributed only in Japan until this species was reported from the South Sea, Korea, in the present study. This study provides descriptions of two species with detailed illustrations by scanning electron microscopy, distributional data, and a taxonomic key to the Korean Gregarinidra species. With the addition of two species reported herein, four Korean Gregarinidra are recorded: G. corbula Seo, 1996, G. furcula new species, G. incrustans(Silén, 1941), and G. serrata (MacGillivray, 1869). Finally, Gregarinidra totals 10 species worldwide.

Though it is not easy for those who study dendrology to memorize all the scientific names of trees, the names remaines in their memory can facilitate the understanding of foreign technical books. The scientific name of a tree indicates characteristics of shape, color, and other aspects of the tree and by analyzing the name we can see common element found in other scientific names of trees. It is helpful to those who want to memorize and study the scientific names of trees if they understand their etymology. The preseut study is the seconds report of the investigation which aims at examining the etymology of the scientific names of native and foreign trees growing in Korea and their original names not only at the habitat but in Japan, China, England, Germany, and France. While the first report, which was made known in Theses Vol. 9. (The City College of Seoul 1975), is the examination of the scientific names of trees belonging to Gymnospermae, the present report is that of scientific names of trees belonging to Piperales: 2 families, 2 genera and 2 species; and trees belonging to Salicales: 1 family, 3 genera, 44 species, 16 varieties, and 3 forms. As the etymology of the scientific names of trees is made clear, this study will help those who want memorize the scientific names and study foreign technical books and it is also useful for international interchange of trees. The classification is depended chiefly on Dendrology by Prof. Lee Tchang-bok and "Plant Resources of Korea" shown in Biblography No. 10; the native names of trees on Jumoku Daizusetsu by Dr. Uehara; and etymology on A source-Book of Biological Names and Terms by E.C. Jager. In the column of etymology of the scientific names for genera, species, varieties and forms, Gr. stands for Greek, L. for Latin, NL. for New Latin, and genit. for genitive.

Two regions of mtDNA genome, cytochrome oxidase subunit I (COI) and 165 ribosomal RNA (165 rRNA) genes, were sequenced for 15 species of the long-horned beetle belonging to four subfamilies and geographic samples of mulberry longicorn beetle, Apriona germari, from two localities in Korea. Ten samples of A. germari collected from Suwon and Busan revealed three COI haplotypes ranging in nucleotide divergence of 0.3% to 0.5%, and the two populations shared one common COI haplotype (80%). The sequence divergence among 15 species of the long-horned beetle was much higher in COI gene (12.3%∼39.4%) than 16S rRNA gene (7.2% to 23.1), and the maximum value in the COI gene is exceptional compared with other relevant studies, including that of Coleoptera. The greatly increased divergence in the COI gene, in facto was stemmed from a peculiar sequence of Prionus insularis belonging to Prioninne, divergence of which ranges from 31.2% to 39.3% from other species. We discussed possible reason of the divergence in this species. Due to the abnormality of COI gene divergence, decrease in phylogenetic signal was severe in COI nucleotide and, subsequently, the converted amino acid sequences, rendering us to put more confidence on the 16S5 rRNA gene data. Although the molecular phylogeny confidently supports the monophyletic origin of Lepturinae, the presence of discrepancy between molecular data and traditional taxonomic views also is a testable hyothesis. One such discrepancy includes taxonomic position of Sophronica obrioides and Theophilea cylindricollis belonging to Lamiinae.

Five types of meju were prepared from 100% defatted soybean (DFSG0), a mixture of 90% DFS and 10% glasswort (DFSG1), a mixture of 80% DFS and 20% glasswort (DFSG2), a mixture of 70% DFS and 30% glasswort (DFSG3), and a mixture of 60% DFS and 40% glasswort (DFSG4). Five types of kanjang were separately prepared from the 5 types of meju by ripening in brine for 6 months. The contents of certain minerals (Mg, Ca, Fe, Mn, and Zn), organic acids (citric acid, malic acid) and the antioxidative effects in the kanjang were increased in proportion to the glasswort content in the meju. However, the free amino acid contents in the kanjang were reduced in proportion to the glasswort content in the meju. DFSG1- and DFSG2-kanjang did not show distinct differences from DFSG0-kanjang based on aroma, flavor, and taste that were compared simply by panel tests. The bacterial and fungal community in the fermented meju and kanjang was not affected by the addition of glasswort to the meju-making process. Bacteria belonging to the Lactobacillus and Bacillus genera and the Lactobacillus family predominated, and yeasts belonging to the Saccharomyces genus and fungi belonging to the Aspergillus genus predominated in the fermented meju and kanjang. In conclusion, the glasswort was a supplement that nutritionally improved the kanjang (except for free amino acid contents) but didn't influence the growth of microorganisms that are responsible for the fermentation of meju and kanjang.

During the extensive survey of the prokaryotic species diversity in Korea, bacterial strains belonging to Betaproteobacteria and Epsilonproteobacteria were isolated from various sources including freshwater, sediment, soil and fish. A total of 23 isolates were obtained, among which 22 strains were assigned to the class Betaproteobacteria and one strain to the class Epsilonproteobacteria. The 22 betaproteobacterial strains were further assigned to Comamonadaceae (11 strains), Burkholderiaceae (6 strains), Oxalobacteraceae (2 strains), Neisseriaceae (1 strain) and unclassified family groups (2 strains). For the strains of Burkholderiaceae, 3 strains were identified as 3 species of Burkholderia, and 2 strains were as 2 species of Cupriavidus. For the strains of Comamonadaceae, 4 strains were identified as 2 species of the genus Hydrogenophaga, 2 strains as 2 species of Acidovorax, 2 strains as 2 species of Limnohabitans, and each of the remaining strains as single species of Comamonas, Curvibacter and Rhodoferax, respectively. For the strains of Oxalobacteraceae, 1 strain was identified as a species of Undibacterium, and the other strain as a species of Herbaspirillum. The strain belonging to Neisseriaceae was identified as a species of Iodobacter. The remaining strains of Betaproteobacteria were identified as species of Sphaerotilus and Methylibium respectively (family unassigned). The epsilonproteobacterial strain was identified as a species of Arcobacter of the family Camplyobacteraceae. The detailed description of each unrecorded species is provided.

This study is on visions having influence on school life to analyze differences between students who have clear visions and those who do not during school life. In order to achieve the goal of this study, the influence which visions have on school life has been analyzed by measuring attitudes towards school life (satisfaction, a sense of belonging, passion, and frustration) depending on students who have visions or those who do not. This analysis shows that the more visions students have, the more satisfaction, a sense of belonging, and passion they have and the less frustration they have. Thus, visions have positive influence on school life and it is essential to reinforce education for students to have clear visions by opening camps to find visions and teaching how to find visions.

This study describes how the illustration book of Korean coastal and offshore fishing boats was published. The illustration book provides information on fisheries which need boats for their fishing operation. The book contains 25 fishing boats belonging to 15 offshore fisheries and six boats belonging to five coastal fisheries totalling 31 boats belonging to 20 kinds of fisheries. Until now, no books were available in Korea on fishing boats which provided illustrated descriptions of their use in fishing. We carried out field and literature surveys of fishing boats for three years (2016-2018) and the results were compiled into three-dimensional modeling images with schematic drawings of fishing boats, along with text explanations. The particulars and technical drawings of lines, general arrangement (GA), fishing gears and methods are collected and summarized. All fishing boats are modeled with 3D color graphics. The particulars and names of the main items of the fishing equipment are presented besides structural parts. In addition the fishing gear, fishing season and grounds, number of crews and target species for each boat are correctly described. The illustration book of Korean coastal and offshore fishing boats will contribute to understanding the current status of fishing techniques in Korea and will assist in developing new types of fishing boats.
