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.

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.

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.

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 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.
Microbial Conversion of Major Ginsenoside Rb1 to Pharmaceutically Active Minor Ginsenoside Rd
Myung Kyum Kim,Jun Won Lee,Ki Young Lee,Deok-Chun Yang 한국미생물학회 2005 The journal of microbiology Vol.43 No.5
More than seventy strains of aerobic bacteria showing -glucosidase activity were isolated from a ginseng field, using a newly designed Esculin-R2A agar, and identified by their 16S rRNA gene sequences. Of these microorganisms, twelve strains could convert the major ginsenoside, Rb1, to the pharmaceutically active minor ginsenoside Rd. Three strains, Burkholderia pyrrocinia GP16, Bacillus megaterium GP27 and Sphingomonas echinoides GP50, were phylogenetically studied, and observed to be most potent at converting ginsenoside Rb1 almost completely within 48 h, as shown by TLC and HPLC analyses.
A report of 7 unrecorded bacterial species isolated from several Jeju soil samples in 2016
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.
