조명희,이명보,이시영,김준범,권봉겸,허영진 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.2
최근 무선 인터넷 및 통신기술의 눈부신 발달과 LBS(location based service)개념을 기반으로 한 mobile GIS 기술 개발은 대규모 산불 발생시 정확한 현장 파악과 신속한 상황보고 뿐만 아니라 사고 예방과 분석·평가에 이르기까지 의사결정지원시스템으로 자리를 잡고 있다. 본 연구에서는 지상진화대의 정확한 위치와 이동상황을 실시간으로 파악하여 안전한 진화작업 유도 및 산불진화 환경정보를 제공을 목적으로 mobile GIS 기술 기반의 산불진화정보 관리시스템을 설계하고 네트워크 부하감소를 위하여 '.gci'라는 공간 데이터 압축기법을 개발하여 면, 선, 주기 데이터에 대하여 51~62%의 높은 압축률을 구현하였다. 따라서 대규모 산불 발생시 일어날 수 있는 안전사고를 미연에 방지하고 사고 발생시 신속한 후속조치로 안전하고 과학적인 산불진화 업무를 수행할 수 있도록 하였다. Recently GPS and mobile GIS technologies based on LBS (location based service) have played an important role as DSS (decision supporting system) for domestic forest fire extinguishment policies. In this study forest fire extinguishments information management system based on mobile GIS technique was designed to seize the exact location on wireless network so that it helps to guide the safe and efficient extinguishments affairs and provide the extinguishments environment toward ground fighting teams and the central forest government in real time. Moreover, possibly to operate this system, the foundation technologies by the name of `. gci such as the spatial data compression method, the spatial data transmission method over wireless network and the spatial analysis interface on PDA should be mainly considered. Especially, in this study the spatial data compression method having high compression rate from 51% to 62% for each polygon, line, and point data, without the loss of data was developed.

Gram-staining-positive, motile, rod-shaped bacteria, designated as <TEX>$H31022^T$</TEX> and H31024 was isolated from rumen contents of a Holstein cow. Optimum growth occurred at <TEX>$25^{\circ}C$</TEX> and pH 7.0 on R2A agar medium. Oxidase and catalase activities are positive. The 16S rRNA gene sequence (1,452 bp) of the new isolates revealed they belong to the genus Kurthia of the phylum Firmicutes. Highest gene sequence similarities were assessed to be with Kurthia massiliensis <TEX>$JC30^T$</TEX> (98.4%), Kurthia senegalensis <TEX>$JC8E^T$</TEX> (97.5%), and Kurthia populi <TEX>$10y-14^T$</TEX> (97.4%). Kurthia sibirica DSM <TEX>$4747^T$</TEX> (97.3%), Kurthia zopfii NBRC <TEX>$101529^T$</TEX> (97.0%), and Kurthia gibsonii NCIMB <TEX>$9758^T$</TEX> (96.7%). DNA G + C content of strains <TEX>$H31022^T$</TEX> and H31024 were 34.4% and 39.7%. Strains <TEX>$H31022^T$</TEX> and H31024 has the following chemotaxonomic characteristics; the major fatty acids are <TEX>$iso-C_{15:0}$</TEX>, <TEX>$iso-C_{14:0}$</TEX> and <TEX>$anteiso-C_{15}$</TEX>; polar lipid profile contained diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), unknown aminophospholipids (APL), unknown glycolipids (GL), unknown phospholipids (PL), and unknown polar lipids (L); the major quinone is MK-7. Based on polyphasic taxonomic analysis, strains <TEX>$H31022^T$</TEX> (<TEX>$=KCTC\;33923^T=JCM\;19640^T$</TEX>) and H31024 (<TEX>$=KCTC\;33924^T=JCM\;19641^T$</TEX>) identified a novel species in the genus Kurthia for which the name Kurthia ruminicola sp. nov. is proposed.

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.

<P>Strain DCY37(T) was isolated from a soil sample of a ginseng field in the Republic of Korea and characterized in order to determine its taxonomic position. Cells were Gram-staining-positive, heterotrophic, strictly aerobic, non-motile short rods. 16S rRNA gene sequence analysis revealed that strain DCY37(T) belongs to the genus Microbacterium. According to 16S rRNA gene sequence analysis, it is closely related to Microbacterium aerolatum DSM 14217(T) (98.8?%), Microbacterium hydrocarbonoxydans DSM 16089(T) (98.5?%), Microbacterium natoriense JCM 12611(T) (98.5?%), Microbacterium foliorum (98.4?%) and Microbacterium phyllosphaerae (98.3?%). However, DNA-DNA hybridization studies showed reassociation values of less than 70?% between representative strains and DCY37(T). The DNA G+C content was 64.5 mol%. Strain DCY37(T) possessed chemotaxonomic markers that were consistent with classification in the genus Microbacterium, i.e. MK-12 and MK-13 as the major menaquinones and anteiso-C(15?:?0), anteiso-C(17?:?0) and iso-C(16?:?0) as the predominant cellular fatty acids. The major cell wall sugars were ribose, xylose and galactose. The diamino acid in cell-wall hydrolysates of strain DCY37(T) was ornithine and major cell-wall amino acids were alanine, glycine, d-glutamic acid and serine. The major polar lipids were glycolipid, phosphatidylglycerol, diphosphatidylglycerol and unknown aminolipids. Based on these data, DCY37(T) (=KCTC 19526(T) =JCM 15516(T)) should be classified as the type strain of a novel species of the genus Microbacterium, for which the name Microbacterium ginsengiterrae sp. nov. is proposed.</P>

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.
