Four actinomycetes which produces extracellular chitinase were isolated from soil and organic matter all over the Chonnam provincial area. The chemical composition, morphological, cultural and physiological properties of isolated strain S-25, S-42, S-172 and S-267 were studied in relation to the toxonomical properties. All of strains contained phospholipids such as phosphatidyl ethanolamine, phosphatidyl inositol and diphosphatidyl glycerol. The components of cell wall in all strains have L, L-DAP, Glutamic acid, Alanine, Glycine and Glucosamine. The surface of spore is smooth and colony is grey in all strains, Based on the results obtained in these experiments all of strains are identified as Streptomyces sp.S-25, Streptomyces sp.S-42, Streptomyces sp.S-l72 and Streptomyces sp.

The 2nd, 3rd, 4th 6th cranial nerve and the ophthalmic division of the 5th cranial nerve are derived from the optic foramen and superior orbital fissure. When these contents are attacked by a trauma the superior orbital fissure syndrome or the more severe orbital apex syndrome are onsetted. As their treatment we can consider the conservative treatment with the hypertonic solution and steroid. Also we can consider the more radical surgery. But their indications are debatable. As the emergency state the treatment plan requires rapid decision and very much considerations equaly. And the legal problems can be happened.

A thorough understanding of the transient behavior during start-up is essential in the design and operation of the heat recovery steam generator(HRSG). During this period of time, material that is exposed to high temperature and experiences a large temperature variation is subject to high thermal stress. In this work, a transient formulation of the HRSG is constructed including the estimation of the thermal stress and fatigue of the drum wall. Start-up behavior of a single-pressure HRSG is analyzed and the effect of bypassing part of the gas turbine exhaust flow on the thermal stress evolution is examined. It is found that the modulation of the gas flow rate using a bypass damper is very useful in view of reducing the thermal stress of the drum and ensuring the fatigue lifetime.

최근 WiBro/WiMAX에서 기지국의 용량증대와 셀의 크기를 확정하는 것을 목적으로 하는 RS(Relay Station)에 대한 표준화가 IEEE 802.16j에서 이루어지고 있다. RS는 기존의 아날로그 중계와 달리 수신신호를 복조 및 복호화한 후 특정 처리과정을 거친 후 다시 부호 및 부호화하여 전송하는 기능을 갖는다. 초고속 휴대인터넷서비스를 제공하고 있는 초고속 무선인터넷서비스 시장에 대한 수요의 증대로 WiBro/WiMax시장의 활성화와 IEEE 802.16j에 대한 표준화의 진척에 따라 WiBro용 RS(Relay Station)상용제품이 조만간 출시 될 것으로 보인다. 본고에서는 WiBrro용 MMR(Mobile Multi-hop relay)기술의 표준화 동향과 요소기술, MMR망의 성능분석에 대해서 기술한다.

Paeonia Suffruticosa and Prunus Persica have been used as oriental medicine for removal of fever, alleviation of pain, an anti-phlogistic effect and removal of extravasated blood. However, it has been never shown the effects of these herbal medicines on anti-inflammatory processes. This experiment was performed to show how these herbs could act as anti-inflammatory medicines at cellular level. Anti-inflammation effects of water extracts from Paeonia Suffruticosa and Prunus Persica as well as their mixture have been investigated, and the results were follows; 1) each extract slightly suppressed the expression and production of inflammatory mediators and enzymes such as NO, iNOS, IL-$1{\beta}$, and TNF-$\alpha$ in lipopolysaccharid(LPS)-stimulated RAW264.7 cells and mouse primary peritoneal macrophages in a dose-dependent manner. These suppressive effects, however, were synergistically increased by their mixture. 2) Each extract of Paeonia Suffruticosa and Prunus Persica insignificantly suppressed the activation and activity of NF-${\kappa}B$ in LPS-stimulated RAW264.7 cells, which controls the expression of inflammatory mediators such as NO, iNOS, IL-$1{\beta}$, and TNF-$\alpha$. However, extract mixture of Paeonia Suffruticosa and Prunus Persica suppressed effectively the activation and activity of NF-${\kappa}B$. 3) Each of Paeonia Suffruticosa and Prunus Persica induced translocation of NF-${\kappa}B$ to the nucleus from the cytosol and DNA-binding activity of nuclear NF-${\kappa}B$ in LPS-activated RAW264.7 cells. The extract mixture of Paeonia Suffruticosa and Prunus Persica showed more significant suppression of the NF-${\kappa}B$ translocation and its DNA-binding activity, as compared to those of the each extract. These results suggest that the extract mixture of Paeonia Suffruticosa and Prunus Persica may affect different control mechanisms for NF-${\kappa}B$ activation and the expression and production of NF-${\kappa}B$-dependent inflammatory mediators, indicating that this extract mixture may be useful for treatment of inflammatory diseases.

김영일,신재영,박형준,Kim, Yeong-Il,Shin, Jae-Young,Park, Hyoung-Jun 한국항해항만학회 2022 한국항해항만학회지 Vol.46 No.4

물동량의 증가로 인해 컨테이너 터미널의 혼잡도가 높아지고 있고 이에 따른 장치장 및 게이트에서의 반출입 차량의 대기시간이 큰 폭으로 길어지고 있어 차량 운용 및 항만 운영 비효율이 극심한 상태이다. 이러한 문제 해결을 위해 부산항의 경우, 항만 공사 및 터미널 측에서 반출입 차량 예약시스템(VBS), 터미널 차량 혼잡도 정보, 예상 작업 처리 시간 정보 등을 서비스하고 있지만 실제 대기시간과 상이한 경우가 있어 가시적인 효과는 여전히 미흡한 실정이다. 따라서 이러한 문제를 해결하기 위한 기초자료로써 본 연구에서는 부산 신항의 컨테이너반출입 정보를 활용하여 딥러닝 기반의 반출입 차량 평균 대기시간 예측 모형을 제시하였다. 실제 평균 대기시간과의 비교를 통해 예측률을 검증한 결과 제시한 예측 모형이 높은 예측률을 보이는 것을 확인하였다. Due to the increase in container cargo volume, the congestion of container terminals is increasing and the waiting time of gate in-out trucks has significantly lengthened at container yards and gates, resulting in severe inefficiency in gate in-out truck operations as well as port operations. To resolve this problem, the Busan Port Authority and terminal operator provide services such VBS, terminal congestion information, and expected operation processing time information. However, the visible effect remains insufficient, as it may differ from actual waiting time.. Thus, as basic data to resolve this problem, this study presents deep learning based average gate in-out truck waiting time prediction models, using container gate in-out information at Busan New Port. As a result of verifying the predictive rate through comparison with the actual average waiting time, it was confirmed that the proposed predictive models showed high predictive rate.

발전소의 실내 소음관리를 위한 소음 매핑 시스템 개발

김영일,김원진,Kim, Young-Il,Kim, Won-Jin 한국음향학회 2021 韓國音響學會誌 Vol.40 No.1

The noise management in the interior of the power plant is difficult because the interior is large and the noise level varies greatly from location to location. Therefore, a noise visualization system capable of analyzing the noise distribution is required in order to effectively manage the interior noise. A noise mapping system was developed that can model the inside of the turbine room and create a noise map by measuring the noise level at selected points. And in order to increase the reliability of the model, the model was modified through a method of comparing the noise map and the actual noise measurement results. Facility abnormalities can be determined through regular analysis of noise maps, and a method of effectively managing the interior noise is presented by comparing and analyzing the frequencies and levels of the current and previous noise at a specific point. By using the mapping system, it is possible to establish noise countermeasures that can improve the working environment, check the machine for abnormalities, and increase the reliability of the facility through preventive maintenance.
