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.

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>

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.

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.

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.

일반적으로 국내에서의 경량기포콘크리트는 건축용 온도구조용 단열재나 토목용 폐공 채움재, 터널의 뒤채 움재 등으로 사용되고 있으며 기타 사무실 바닥 충전재, 경량블록제조 등으로 사용되어지고 있다. 이러한 경량기포콘 크리트의 사용범위를 확대하여 연약지반에 도로건설시 등간격으로 말뚝을 설치하여 기층으로 사용하는 공법을 연구 중에 있다. 본 연구에서는 경량포장체의 연약지반에서의 거동 특성을 분석하기위해 지오센트리퓨지 시험을 이용하였 다. 실제 포장체를 1/30로 축소한 슬래브 형태의 모형을 카올리나이트로 조성된 연약지반에서 시험을 실시하였다. 말 뚝 배열은 무리말뚝(36본 3×12)로 제작하여 사용하였다. 시험 중력 레벨은 실중력의 30배로 원심력을 작용하여 실험 하였으며 이때 작용하는 경량포장체 모형의 거동특성을 바탕으로 실제 경량포장체의 거동특성을 추정하였다. FMA해 석결과의 10배인 39.4kg(실제 하중35ton)의 횡하중를 가했을 경우 7.8mm(실제 거동 23.4mm)의 미세한 거동만 있었다. In general, Korean Lightweight Concrete used Heat insulating material for building and filler for civil construction, backfill material for tunnel, office floor fillers, lightweight blocks and so on. These expand the range of use ALC(autoclaved lightweight concrete) on the soft-ground at regular intervals during road construction by installing piles used as substrates for the process is under study. In this study, behavior characteristics on the soft-ground of pavement analysis was used to test the geo-Centrifuge. Prototype pavement reduced to 1/30 slab form of the composition as kaolinite model tests were conducted in the soft ground. Pile Arrangement (having 36 component pile with an array of 3 × 12) was used to group of piles. Tests of gravity 30 level the centrifugal force acting Light-weight pavement models. Based on the Prototype pavement of the behavior characteristics of pavement behavior characteristics were estimated. FMA analysis of the 10 times as big 39.4kg (actual load 35 ton) of the lateral load is applied to the case 7.8mm (actual behavior 23.4mm) behavior was fine.
