A Gram-negative bacterium was isolated from mushroom media that markedly reduces the level of extracellular toxins (i.e., tolaasins) produced by Pseudomonas tolaasii, the most destructive pathogen of cultivated mushrooms. The HC1 strain was selected as detoxifying tolaasin by bioassay on potato and it was identified Pseudomonas sp. by the cultural, morphological and physiological characteristics, and analysis of the 16S rRNA.. The isolated bacterium is saprophytic but not parasitic nor pathogenic to cultivation mushroom. The isolated bacterium for P. tolaasii cell, was sufficient for detoxification in vitro. Inoculation of the isolated bacterium prevents the development of bacterial disease in Pleurotus ostreatus, Flammunia velutipes and Agaricus bisporus. Control efficacy of brown blotch of strain HC1 treatment was 69, 68 and 55% on Agaricus bisporus, Flammulina velutipes and Pleurotus ostreatus, respectively. The suppressive bacterium may be useful in future for the development of biocontrol system and the construction of genetically modified edible fungi resistant to the disease caused by P. tolaasii.

본 사례연구는 창업으로 성공한 창업가(entrepreneur)의 경영권 승계에 대한 철학을 그의 사업 역정을 통하여 살펴보는 데 목적이 있다. 흔히 경영자(manager)의 눈에는 돈이 안 되는 문제부터 보이지만, 사업가(businessman)의 눈에는 돈이 되는 사업부터 보인다고 한다. 과연 우리나라에 창업 사업가로서 기업가 정신(entrepreneurship)을 잃지 않으면서 한편으로는 경영자로서 '創業보다 어렵다는 守成의 길'을 성공적으로 영위해 온 인물은 얼마나 되는가? 그리고 언젠가는 자신의 사업체를 누군가에게 물려줄 수밖에 없는 상황에서 경영권 승계는 과연 어떻게 이루어지고 있는가? 이에 대한 논의를 위해 본 사례는 코텍 이한구 회장과의 인터뷰를 바탕으로 사업가이자 최고경영자로서 사업과 인생에 대한 관점 및 그의 경영권 승계에 대한 철학을 분석함으로써 강소기업으로 성공한 창업가(entrepreneur)는 물론 대기업의 경영권 승계 관행에 대한 새로운 시사점을 던지고자 한다. The purpose of this case study is to analyze the philosophy of an entrepreneur (CEO and Chairman of Kortek) being appeared in the process of management succession. The 27 years history of a start-up firm introduced in this analysis maneuvered its challenging business based on Chairman Lee's business insights and philosophy since its foundation in 1987. Kortek, as a hidden champion, is the No. 1 in the field of Gaming Video Display Monitor delivering more than 70% of Video Slut Machines in the U.S. market. Compared to the ordinary managers who are in seeking of dysfunctions of daily management and operations, the founder and current CEO and Chairman Han-Gu Lee pursued to catch out the money-making businesses with his talented entrepreneurship. Despite of his unprecedent success as an industrial display monitor maker, recently he has been deliberately considered about the management succession scenarios for the vision of his cherished Kortek to keep as a sustainable company. In this case study, we analyzed the 3 scenarios being evaluated during more than 2 years by Chairman Lee. And as the result and performances after his decision to accept M&A with IDIS Holdings show a sustainable growth, we could extract strong implications not only for the Korean CEOs of hidden champions who have experiences as start-up founder but also other major companies being faced with such an agony in management succession.

SOI 기판에 형성된 MOSFET의 특성 연구

한명석,이찬희,홍신남 한국항공대학교 1995 論文集 Vol.33 No.-

Thin film SOI 소자는 short channel effect 감소, subthreshold slop의 개선, 높은 이동도, 낮은 기생 캐패시터, latch-up현상이 없는 등의 여러가지 장점들을 가지고 있다. 이것이 ULSI에 대해 실현 가능한 기술이 된 것은 최근에 발달된 양질의 thin film SOI 기관 제작기술에 기인한 것이다. 그렇지만 current kink와 early breakdown 같은 floating body effect와 source/drain 저항의 증가라는 두가지의 큰 문제점을 가지고 있다. 본 연구에서는 concave 구조를 가지는 SOI MOSFET 형태를 통해 문제를 풀어보고자 하였다. 제안된 concave SOI 구조는 항복전압을 높이고 드레인 영역에서의 전계를 감소시켜 kink 현상의 원인이 되는 impact ionization이 발생할 확률을 줄이는 결과를 얻을 수 있었다. Thin-film SOR(Silicon-On-Insulator) devices offer unique advantages such as reduction in short channel effects, improvement of subthreshold slope, higher mobility, low parasitic capacitance, latch-up free natere, and so on. This is available technology for ULSI due to recent advances in high quality thin film SOI process technology. However, Thin film SOI devices have several problems-floating body effects, current kink, early breakdown effects, increase in parasitic source/drain resistances. In this paper, a SOI MOSFET with concave structure is analyzed for a sub-half micron regime to solve the above problems. Proposed concave SOI structure showed the increased breakdown voltage and the decreased impact ionization due to the lower electric field near the drain region.

한찬수,황인섭 순천향대학교 기초과학연구소 2000 순천향자연과학연구 논문집 Vol.6 No.2

An electron spin resonance study of the Fe3+-center in Sapphire has been carried out at room temperature employing the JEOL JE-TE100 X-band spectrometer. The spin Hamiltonian parameters of the center are determined from the measurements using the least-squares method. The sample was prepared from a synthetic corundum doped with iron and titanium, which was grown in the Korean Research Institute of Chemical Technology in Taedok Science Town. It is found that the c-axis is made an angle of about 63˚ with the growing axis of the crystal. All 190 experimental resonance points are used to fit the ESR parameters, the data are well consistent with our calculations with the parameters. There are still unidentified ESR signals in the sample.

This research was designed to describe the effect of teenager's participation in Judo training to the social relationship. We examined the effect of teenagers participating in Judo training and non-participated teenagers to the subordinate factor of the social relationship inclination ; sympathy, receptiveness, sociality and friendship. The subjects for this research were total 394 students participating in Judo class and non-participated students among middle school based on Daejeon city by the Stratified Cluster Random Sampling method. To investigate this research, we modified and supplemented the standardized questionnaire of human nature test and personal relations inclination test for teenagers. The reliance coefficient was shown as the value of a'=.5726∼.6816 We applied for SPSS v10.0 for Windows to progress the data of study. The result of executing Analysis of Covariance, ANCOVA to investigate the effect of teenager's participation in Judo training to the social relationship inclination is as follows; a. The participation in Judo training for the class affects the sympathy as the subordinate factor of the social relationship inclination. b. The participation in Judo training for the class affects the receptiveness as the subordinate factor of the social relationship inclination. c. The participation in Judo training for the class affects the sociality as the subordinate factor of the social relationship inclination. d. The participation in Judo training for the class affects the friendship as the subordinate factor of the social relationship inclination.

ATSC test pattern for evaluating the image quality of ATSC display system has high quality and high compression rate. In this paper, we implemented ATSC test pattern that has high quality and high compression rate by minimizing the number of DCT coefficients block data. To minimize this DCT coefficients, the proposed test pattern is optimized for partition of DCT block. To test variable image quality of ATSC display system, quantization error and display test pattern is included the ATSC test pattern.

수정내의 Si 자리에 대치되고 Li 에 의하여 전하보상된 Fe 공명중심에 대한 ESR 연구

한찬수,맹주양 순천향대학교 1994 논문집 Vol.17 No.3

The ESR parameters of the spin Hamiltonian for the so-called S1-center in cultured Quartz were measured at 40 K by the least squares fitting method. The temperature dependence of the parameters of the S1-center in quartz was also analized over a range of 20 - 295 K, using experimental results. Absolute values of the principal components of the D-tensor are decreased with increasing temperature, and the z-direction of the principal axes is also changed slightly over this temperature range.
