Paenibacillus filicis sp. nov., Isolated from the Rhizosphere of the Fern
김병천,Mi Na Kim,Kang Hyun Lee,Sun Beom Kwon,배경숙,신기선 한국미생물학회 2009 The journal of microbiology Vol.47 No.5
A Gram-positive and endospore-forming bacterial strain, designated S4T, was isolated from the rhizosphere of ferns in Daejeon, Republic of Korea. This isolate is strictly aerobic, motile, and rod-like in shape, and it is positive for catalase, oxidase, esterase lipase, and β-galactosidase activities. In addition, this strain grows when cultured at temperatures between 15 and 37°C and at pH values ranging from 5.5 to 9.0. The DNA G+C content was determined to be 53.2 mol%. Strain S4T has meso-diaminopimelic acid in the cell-wall peptidoglycan; it also contains menaquinone 7 (MK-7) as the predominant isoprenoid quinone and anteiso-C15:0 (57.5%), iso-C16:0 (11.3%), and C16:0 (9.4%) as the major cellular fatty acids. Phylogenetic analysis based on alignments of the 16S rRNA gene sequence showed that S4T is affiliated with a cluster of strains within the genus Paenibacillaceae and is most closely related to Paenibacillus chinjuensis WN9T, with 96.8% similarity. Based on the phylogenetic and phenotypic characteristics of strain S4T, we believe that this isolate should be distinguished from all type species of the genus Paenibacillus and should thus represent a novel taxon within the genus Paenibacillus. We propose naming this type species Paenibacillus filicis sp. nov. for the rhizosphere isolate; the type strain will be known as S4T (=KCTC 13693T =KACC 14197T =JCM 16417T).

A novel cellulolytic bacterium, strain S23T, was isolated from the rhizosphere of the pine trees in Daejeon, Republic of Korea. This isolate was Gram-positive, strictly aerobic, rod-shaped, catalase-negative, oxidase- positive, motile by means of peritrichous flagella, and tested positive for alkaline phosphatase, esterase lipase, leucine arylamidase, α-galactosidase, and β-galactosidase activities. The DNA G+C content was 49.5 mol%. The main cellular fatty acids were anteiso-C15:0 (51.9%), iso-C16:0 (14.7%), and iso-C15:0 (13.2%). The major isoprenoid quinone was menaquinone 7 (MK-7). Diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. Comparative 16S rRNA gene sequence analysis showed that this strain clustered with Paenibacillus species. The 16S rRNA gene sequence similarity values between S23T and other Paenibacillus species were between 89.9% and 95.9%, and S23T was most closely related to Paenibacillus tarimensis SA-7-6T. On the basis of phylogenetic and phenotypic properties of strain S23T, the isolate is considered as a novel species belonging to the genus Paenibacillus. Therefore, the name, Paenibacillus pinihumi sp. nov., is proposed for the rhizosphere isolate; the type strain is S23T (=KCTC 13695T =KACC 14199T =JCM 16419T)

Strain S22T, a novel cellulolytic bacterium was isolated from the rhizosphere of pine trees. This isolate was Gram-reaction positive, motile and rods, and formed terminal or subterminal ellipsoidal spores. S22T represented positive activity for catalase, oxidase, esterase (C4), esterase lipase (C8), β-galactosidase, leucine arylamidase, and hydrolysis of esculin. It contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall. The predominant isoprenoid quinone was menaquinone 7 (MK-7), and the major cellular fatty acids were anteiso-C15:0 (52.9%), iso-C16:0 (11.3%), and iso-C15:0 (10.0%). The DNA G+C content was 43.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that this isolate belonged to the family Paenibacillaceae. S22T exhibited less than 97.0% 16S rRNA gene similarity with all relative type strains in the genus Paenibacillus, and the most closely related strains were Paenibacillus anaericanus MH21T and Paenibacillus ginsengisoli Gsoil 1638T, with equal similarities of 95.8%. This polyphasic evidence suggested that strain S22T should be considered a novel species in the genus Paenibacillus, for which the name, Paenibacillus pini sp. nov., is proposed. The type strain is S22T (=KCTC 13694T =KACC 14198T =JCM 16418T)

Cart-pole 균형 문제는 유전자 알고리즘, 인공신경망, 강화학습 등을 이용한 제어 전략 분야의 표준 문제이다. 본 논문에서는 cart-pole 균형문제를 해결하기 위해 실시간 강화 학습을 이용한 접근 방법을 제안하였다. 본 논문의 목적은 cart-pole 균형 문제에서 OREL 학습 시스템의 학습 방법을 분석하는데 있다. 실험을 통해, 본 논문에서 제안한 OREL 학습 방법은 Q-학습보다 최적 값 함수에 더 빠르게 접근함을 알 수 있었다. The cart-pole balancing problem is a pseudo-standard benchmark problem from the field of control methods including genetic algorithms, artificial neural networks, and reinforcement learning. In this paper, we propose a novel approach by using online reinforcement learning(OREL) to solve this cart-pole balancing problem. The objective is to analyze the learning method of the OREL learning system in the cart-pole balancing problem. Through experiment, we can see that approximate faster the optimal value-function than Q-learning.

Where are we now after 22 years since the assertion of “Training 0.1 Million Hackers” emerged? According to the survey of the experts on this matter, there are only around 200 white hackers. Meanwhile, both socialistic countries such as North Korea, China and Russia and democratic countries such as the U.S., U.K., and Japan had been long since they prepared aggressive cybersecurity strategies. On the premise that fostering hacker is the top priority of the country’s agenda, this thesis is to figure out what kind of hindrance in psychological variable blocks transition of Black Hackers to White Hackers, through interviews and survey of experts.
