The content of oxidation-reduction in the chemistry textbooks from middle school to college was analyzed to see the effective connection of curricular articulation. For this purpose, oxidation-reduction content between the school unit were selected in chemistry textbooks and formed five types of classification from groups of "first concept", "same concept", "overlap", "development" and "gap". The result indicated that there was a deep big gap from middle school to senior high school and the effectiveness from senior high school to college was looked acceptable. Finally, the new concept maps between the school unit were suggested.

For the collection of indigenous prokaryotic species in Korea, 35 strains within the class Actinobacteria were isolated from various environmental samples (animals and clinical specimens) in 2017. Each strain showed high 16S rRNA gene sequence similarity (>98.8%) and formed a robust clade with recognized actinobacterial species. The isolates were assigned to 35 species, 22 genera, 15 families, and 8 orders of the class Actinobacteria. There are no official descriptions of these 35 bacterial species in Korea. Morphological properties, basic biochemical characteristics, isolation source, and strain IDs are included in the species descriptions.

In 2016, as a subset study to discover indigenous prokaryotic species in Korea, a total of 15 bacterial strains were isolated and assigned to the class Betaproteobacteria. From the high 16S rRNA gene sequence similarity (>98.8%) and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to each independent and predefined bacterial species. There is no official report that these 15 species have been described in Korea; therefore, 1 strain of the Aquitalea, 5 strains of the Paraburkholderia, 2 strains of the Comamonas, 1 strain of the Cupriavidus, 1 strain of the Diaphorobacter, 2 strains of the Hydrogenophaga, 1 strain of the Iodobacter, 1 strain of the Massilia and 1 strain of the Rhodoferax within the Betaproteobacteria are described for unreported bacterial species in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, and isolation sources are also described in the species description section.

For the collection of indigenous prokaryotic species in Korea, 77 strains within the phylum Actinobacteria were isolated from various environmental samples, fermented foods, animals and clinical specimens in 2019. Each strain showed high 16S rRNA gene sequence similarity (>98.8%) and formed a robust phylogenetic clade with actinobacterial species that were already defined and validated with nomenclature. There is no official description of these 77 bacterial species in Korea. The isolates were assigned to 77 species, 31 genera, 18 families, 14 orders and 2 classes of the phylum Actinobacteria. All the strains except one Coriobacteriia strain were affiliated within the class Actinomycetia. Among them, the orders Streptomycetales and Microbacteriales were predominant. A number of strains were isolated from forest soils, riverside soils, and ginseng cultivated soils. Twenty-nine strains were isolated from 'Protected Ecosystem and Scenery Areas'. Morphological properties, basic biochemical characteristics, isolation source and strain IDs are described in the species descriptions.

In the project of a comprehensive investigation of indigenous prokaryotic species in Korea, a total of 39 bacterial strains phylogenetically belonging to the classes Betaproteobacteria and Gammaproteobacteria were isolated from various environmental sources such as soil, cultivated soil, sludge, seawater, marine sediment, algae, human, tree, moss, tidal flat, beach sand and lagoon. Phylogenetic analysis based on 16S rRNA gene sequences revealed that 39 strains showed the high sequence similarities (≥98.7%) to the closest type strains and formed robust phylogenetic clades with closely related species in the classes Betaproteobacteria and Gammaproteobacteria. In the present study, we report 14 species of 9 genera of four families of two orders in the class Betaproteobacteria and 25 species of 21 genera of 15 families of eight orders in the class Gammaproteobacteria, which have not been reported in Korea. Morphological, biochemical, and physiological characteristics, isolation sources, and NIBR deposit numbers are described in the species descriptions.
Effects of Particle Size and Cement Replacement of LCD Glass Powder in Concrete
Kim, Seong Kyum,Kang, Su Tae,Kim, Jin Kwang,Jang, Il Young Hindawi Limited 2017 Advances In Materials Science And Engineering Vol.2017 No.1
<P>The high quality liquid crystal display (LCD) processing waste glass (LPWG) generated from the manufacturing process of Korea’s LCD industries, having the world’s highest technological level and production, was finely ground into particles smaller than cement particles (higher fineness than OPC) to verify their applicability and performance as a replacement for cement. For a concrete mix having a W/B ratio of 0.44, cement was replaced with LPWG glass powder (LGP) at ratios of 5, 10, 15, and 20% (LGP12) and 5 and 10% (LGP5) according to the particle size to prepare test cylinder specimens, which were tested with respect to air contents, slump in fresh concrete, and compressive strength and splitting tensile strength of hardened concrete. The microstructure of the concrete specimens was analyzed through Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), and a Mercury Intrusion Porosimetry (MIP). Replacement of cement with LGP for cement could effectively decrease the quantity of cement used due to the excellent performance of LGP. It may positively contribute to the sustainable development of the cement industry as well as waste recycling and environment conservation on a national scale.</P>
