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.

Strain Kw07$^T$, a Gram-negative, non-spore-forming, rod-shaped bacterium, was isolated from granules in an Up-flow Anaerobic Sludge Blanket (UASB) bioreactor used in the treatment of brewery wastewater. 16S rRNA gene sequence analysis revealed that strain Kw07T belongs to the a-4 subclass of the Proteobacteria, and the highest degree of sequence similarity was determined to be to Sphingopyxis macrogoltabida IFO 15033T (97.8%). Chemotaxonomic data revealed that strain Kw07T possesses a quinone system with the predominant compound Q-I0, the predominant fatty acid C,s:, OJ7c, and sphingolipids, aU of which corroborated our assignment ofthe strain to the Sphingopyxis genus. The results of DNA-DNA hybridization and physiological and biochemical tests clearly demonstrated that strain Kw07T represents a distinct species. Based on these data, Kw07T (= KCTC 12209T = NBRC 100800T) should be classified as the type strain for a novel Sphingopyxis species, for which the name Sphingopyxis granuli sp. novo has been proposed.

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.
Complete Genome Sequence of Hymenobacter sedentarius DG5BT, a Bacterium Resistant to Gamma Radiation
Myung Kyum Kim,Myung-Suk Kang,Sathiyaraj Srinivasan,Do Hee Lee,Seung-Yeol Lee,Hee-Young Jung,H Y. Jung 대한독성 유전단백체 학회 2017 Molecular & cellular toxicology Vol.13 No.2
The ionizing radiation toxicity becomes a primary concern of the world; several exceptional attention was given to the resistance mechanisms of the radiation-resistant bacteria. Hymenobacter sedentarius DG5BT strain isolated from the gamma ray-irradiated soil samples shows resistance against gamma and UV radiation; however, their level of resistance is lower than that of other radiation resistant bacteria. To gain insight of radiation resistance, we carried out the whole genome sequencing of this strain. The genome of DG5BT strain is comprised of 4,868,852 bp (G+C content of 60.96%) including 3,994 protein-coding genes and 55 RNA genes. When compared with other bacteria, there are differences in compositions and copy numbers of several genes involved in DNA repair pathways and defense mechanism against protein damages. In this study, we discuss the implication of such findings concerning other radiation resistant bacteria.

Deinococcus actinosclerus BM2<sup>T</sup> (GenBank: KT448814) is a radio-resistant bacterium that is newly isolated from the soil of a rocky hillside in Seoul. As an extremophile, D. actinosclerus BM2<sup>T</sup> may possess anti-inflammatory properties that may be beneficial to human health. In this study, we evaluated the anti-inflammatory effects of BM2U, an aqueous extract of D. actinosclerus BM2<sup>T</sup>, on lipopolysaccharide (LPS)-mediated inflammatory responses in RAW264.7 macrophage cells. BM2U showed antioxidant capacity, as determined by the DPPH radical scavenging (IC<sub>50</sub> = 349.3 μg/ml) and ORAC (IC<sub>50</sub> = 50.24 μg/ml) assays. At 20 μg/ml, BM2U induced a significant increase in heme oxygenase-1 (HO-1) expression (p < 0.05). BM2U treatment (0.2-20 μg/ml) significantly suppressed LPS-induced increase in the mRNA expression of proinflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-6 (p < 0.05). BM2U treatment also suppressed the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), which are involved in the production of inflammatory mediators. BM2U treatment also inhibited the activation of nuclear factor-κB (NF-κB) and mitogen-activated protein kinases (MAPKs): JNK, ERK, and p-38 (p < 0.05). Collectively, BM2U exhibited anti-inflammatory potential that can be exploited in attenuating inflammatory responses.

In 2016, as part of a larger effort to discover indigenous prokaryotic species in Korea, we isolated the family Deinococcaceae and Planctomycetaceae as unrecorded bacterial species. From the high 16S rRNA gene sequence similarity (>98.5%) and formation of a robust phylogenetic clade with known species, it was determined that each strain was a distinct bacterial species. There are no official reports that these two species have been described in Korea; therefore, the bacterial strains of Deinococcus and Blastopirellula are described for the first time in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, and isolation sources are also described in the species description section.

Kim, Ju-Young,Jang, Jun Hwee,Maeng, Soohyun,Kang, Myung-Suk,Kim, Myung Kyum The National Institute of Biological Resources 2018 Journal of species research Vol.7 No.2
Seven bacterial strains, 15J4M-1, 15J13-8, 16MFM10, 15J1-8, SR1-5-4, 15J13-6, and 15J8-11 assigned to the phylum Actinobacteria, Bacteroidetes, and Firmicutes were isolated from soil samples collected from Jeju, Korea. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strains 15J4M-1, 15J13-8, 16MFM10, 15J1-8, SR1-5-4, 15J13-6, and 15J8-11 were most closely related to Bacillus selenatarsenatis $SF-1^T$ (with 99.4% similarity), Brevibacterium luteolum $CF87^T$ (99.5%), Carnobacterium iners CCUG $62000^T$ (99.6%), Exiguobacterium profundum $10C^T$ (99.3%), Larkinella insperata LMG $22510^T$ (99.3%), Pseudokineococcus lusitanus CECT $7306^T$ (99.4%), and Spirosoma endophyticum $EX36^T$ (99.3%), respectively. This is the first report of these seven species in Korea.
