The history of nuclear fusion research in Korea is rather short compared to that of advanced countries. However, since the mid- 1990s, at which time the construction of KSTAR was about to commence, fusion research in Korea has been actively carried out in a wide range of areas, from basic plasma physics to fusion reactor design. The flourishing of fusion research partly owes to the fact that industrial technologies in Korea including those related to the nuclear field have been fully matured, with their quality being highly ranked in the world. Successive pivotal programs such as KSTAR and ITER have provided diverse opportunities to address new scientific and technological problems in fusion as well as to draw young researchers into related fields. The frame of the Korean nuclear fusion program is now changing from a small laboratory scale to a large national agenda. Coordinated strategies from different views and a holistic approach are necessary in order to achieve optimal efficiency and effectiveness. Upon this background, the present paper reflects upon the road taken to arrive at this point and looks ahead at the coming future in nuclear fusion research activities in Korea.

대장균군 검사용 간이 시험지는 본 실험실에서 국내 최초로 고안, 개발하였으며 이 간이 시험지법은 현장 검사법의 하나로 대장균군이 내는 succinic acid dehydrogenase 때문에 tetrazolium salt 가 환원되어 적색 반점을 형성하는것을 이용한 방법으로서 이 간이 시험지의 제조는 대체로 종래의 표준 평판법과 거의 동일한 조성의 배지와 시약을 사용하여 여지에 흡착시킨 후, 건조시켜 (60℃) 멸균한 것으로 표준 평판법과 어떤 상관관계가 있는가를 검토하였다. 이 간이 시험지의 제조에서는 bile salt No.3를 deoxycholate로 대체하여 제조 원가를 절감하였고, 또한 일본에서 현재 시판되고 있는 제품과 품질 비교시험을 하여 더 좋은 결과를 얻었으며 종래의 표준 평판법과 비교하였을 때도 오히려 표준 평판법(24-48시간 배양)보다 빠른 시간(16-20시간 배양)내에 판정할 수 있는 이점이 있으며, 표준 평판법에서는 없어서는 안될 배지나 배양 접시, pipette등의 자료및 기구가 일체 필요없고 언제 어디서나 현장에서 직접 시험할 수 있어 매우 간편하며 또한 저렴한 가격으로 제조 할 수 있는 경제성이 높은 이점을 갖고 있다. The objective of this study was to develop a paper strip which could determine E. coli qualitatively and quantitatively in water, wastewater, drinks, or food. This paper strip method was a simple and rapid test method that determine E. coli by visual identification. In this study, nutrient culture media were formulated and characterized for optimum conditions. Paper strips were then prepared by impregnating into the media and dried at 60℃. The test procedure is quite simple to use. The paper strip was dipped into a sample, and excess sample was removed. The strip was then incubated at 37℃ for 16 to 20 hours and the number of colonies on the strip was counted. The color of the colony spots produced by microorganisms varied depending on the media formulation. Violet-red spots were produced by E. coli. The test method was simple, rapid and no special laboratory equipment was necessary for visual identification. Therefore, this test method is applicable to on-site tests such as field tests or home tests. The paper strip method was compared with the standard agar plate method and Japanese commercial product. The method of the economical preparation of test strips was studied for production on industrial scale.

Lee, In-Gu,Kim, Young-Min,Lee, Hyung Won,Jeon, Jong-Ki,Lee, Heejin,Jung, Sang-Chul,Kim, Seungdo,Watanabe, Atsuichi,Park, Young-Kwon American Scientific Publishers 2017 Journal of Nanoscience and Nanotechnology Vol.17 No.11

<P>Mesoporous materials produced from zeolite HBeta, (MMZHBeta) with different Si/AI ratios were synthesized and applied for the first time to the catalytic pyrolysis of Geodae-Uksae 1, a new energy crop discovered in South Korea. The non-catalytic pyrolysis and in-situ catalytic pyrolysis of Geodae-Uksae 1 were tested rapidly using a pyrolyzer-gas chromatography/mass spectrometry/flame ionization detector/thermal conductivity detector. The main pyrolyzates of Geodae-Uksae 1 consisted of levoglucosan, acetic acids, furans, and phenolics, which were upgraded efficiently into furans and aromatics using the MfV148,,a catalysts. Between the MMZHoeta catalysts, MMZHeeta (25) produced larger amounts of furans and aromatics than MMZHeeta (300) owing to its higher acidity. The increase in the catalyst to biomass ratio (from 2/1 to 6/1) and reaction temperature (from 500 to 600 degrees C) enhanced the formation of aromatics.</P>

외환위기에 따른 IMF지원체제라는 어려운 경제환경하에서 현정부들어 시행된 국내경제 정책의 미숙과 지속적인 실패로 국내금융산업은 매우 어려운 상황에 직면하게 되었다. 특히 무분별한 통제 정책으로 빅딜 등 사상초유의 구조조정이 이루어지면서 주요 국내 금융기관의 상당수가 헐값으로 외국기업에 팔리는 해프닝이 벌어지고 있다. 국내 금융산업이 사상초유의 은행퇴출 및 강제 합병, 국내은행의 해외덤핑매각, 엄청난 공적자금의 투입, 정치권의 각종 통제, 급격한 금리인하 등 예기치 못한 변화를 겪으면서 국내 은행들은 생존자체를 염려해야 하는 상황이 되었다. 이제 은행은 새로운 고객의 유치는 물론 기존의 고객을 경쟁사에 빼앗기지 않고 유지해야하는 관계마케팅전략에 관심을 기울여야 한다. 이 분야는 최근에 서비스산업에서 가장 중요하게 언급되고 있는 부분이다. 따라서 본 연구는 국내 금융기관의 거래관계 유형을 파악하고 성공적인 전략을 찾아내는 데 그 목적을 두고 있다. 연구결과 국내은행이 고객과의 거래관계를 유지하는 전략유형은 크게 4가지로 나타났다. 즉, 사회적 결속, 구조적 결속, 재무적 결속, 기타 결속 등으로 나타났다. 그리고 이러한 전략 중에서 은행의 성과에 유용한 전략은 성과유형별로 다소 차이는 있으나 대체적으로 재무적 결속, 구조적 결속, 사회적 결속 순으로 나타났다. Service firms have always been relationship oriented. the nature of service businesses is relationship based. As service firms, like banks, insurance firms, have grown, The masses of consumers have made the establishment of true relationships more difficult. Understanding the motivations of consumers to engage in relationships with marketers is important for both practitioners and marketing scholars. To develop an effective theory of relationship marketing, It is necessary to understand what motives consumers to reduce their available market choices. This article focuses on the development of the successful relationship strategies in domestic banks. The results of this study show the four types of relationship strategies - social bonds, structural bonds, financial bonds, and other bonds. Although the effectiveness of these strategies differs as the types of performances, All four types of relationship strategies are essential for building and maintaining relationships with customers. Totally, the order of influences on the performance is as follows; financial bonds, structural bonds, and social bonds.

Hybridoma producing monoclonal antibodies reactive with the β-chain of interleukin-2 receptor (IL-2R) were generated from mice immunized with a synthetic peptide of 19 amino acids. The synthetic peptide constitutes strongly hydrophilic region of extracellular domain of the IL-2R molecules(residues 32-50) as revealed by hydrophathy plot analysis. Hybridomas were screened by ELISA using Hut102 cells and the synthetic peptide as antigenic moiety, and by miasuring the binding activity of antivodies to the Hut102 cell surface that was monitored by a flow cytometer. The antibodies were further screened by their inhibitory effect against the interaction between IL-2R and interleukin-2(IL-2). Antibodies were further characterized by immunoprecipitation followed by autoradiography to reveal that the antibodies recongnize the 75 KD protein molecules expressed on the Hut102 cell surface and human peripheral blood mononuclear cells(PBMC) shich confirms the antigenic moiety to be β-chain of IL-2 recepter molecules.

Catalytic Pyrolysis of Cellulose over SAPO-11 Using Py-GC/MS

Lee, In-Gu,Jun, Bo Ram,Kang, Hyeon Koo,Park, Sung Hoon,Jung, Sang-Chul,Jeon, Jong-Ki,Ko, Chang Hyun,Park, Young-Kwon Korean Chemical Society 2013 Bulletin of the Korean Chemical Society Vol.34 No.8

The catalytic pyrolysis of cellulose was carried out over SAPO-11 for the first time. Pyrolyzer-gas chromatography/mass spectroscopy was used for the in-situ analysis of the pyrolysis products. The acid sites of SAPO-11 converted most levoglucosan produced from the non-catalytic pyrolysis of cellulose to furans. In particular, the selectivity toward light furans, such as furfural, furan and 2-methyl furan, was high. When the catalyst/cellulose ratio was increased from 1/1 to 3/1 and 5/1, the increase in the quantity of acid sites led to the promotion of deoxygenation and the resultant increase of the contents of light furan compounds. Because furans can be used as basic feedstock materials, the augmentation of the economical value of bio-oil through the catalytic upgrading over SAPO-11 is considerable.

Small Bowel Infarction by Mesenteric Venous Thrombosis due to Methylenetetrahydrofolate Reductase Gene Mutation

In Young Park,Byoung Joo Do,Jae Sung Ahn,Jae Hyuk Lee,Jun Ho Park,Jin Gu Kang,Bo Kyung Yang,Hyoung Su Kim 순천향대학교 순천향의학연구소 2014 Journal of Soonchunhyang Medical Science Vol.20 No.2

Acute mesenteric venous thrombosis (MVT) is an uncommon form of intestinal ischemia with high mortality and usually occurs in the setting of preexisting comorbidities including thrombophilia and abdominal inflammatory conditions. Hyperhomocysteinemia has been known to be a risk factor for thromboembolism, often located on an unusual site. Considering that homocysteine metabolism is determined genetically to a high degree, a mutant of methylenetetrahydrofolate reductase (MTHFR) C677T causes hyperhomocysteinemia, leading to thrombophilia. Until now, there have been few reports of MVT associated with MTHFR gene mutation. We, herein, report a case of small bowel infarction associated with MVT by MTHFR gene mutation in an adult without any other risk factors of thrombophilia.
