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.

한종현,강성용,정현우,오찬호,권진,은재순 대한본초학회 1997 大韓本草學會誌 Vol.12 No.1

The effects of several tonifying prescriptions on the apoptosis of transplanted L1210 cells and the regulation of immune cells in L1210-transplanted mice were studied. Sa-Mul-Tang(SMT), Sa-Kunja-Tang(SKT), Sipjeon-Daebo-Tang(SDT) accelerated the apoptosis of transplanted L1210 cells, and SMT and SKT reduced the mitochondrial transmembrane potential of transplanted L1210 cells. SMT promoted the proliferation of thymocytes and splenocytes in L1210-transplanted mice. Whereas SMT increased CD8+ T_c/T_S cell, Bojung-Ikki-Tang(BIT) decreased CD4+ T_H cell population in the thymocytes of L1210-transplanted mice. SMT and SKT increased the lucigenin chemiluminescence from peritoneal macrophage of L1210-transplanted mice. These results indicate that SMT and SKT have an inductive action of apoptosis of transplanted L1210 cells and peritoneal macrophage activation.

스포츠의 경기실적 산정모형의 분석 : 농구의 평가공식을 중심으로 Focused on a Estimated Formula of Basketball

한필수,김찬회 한국스포츠리서치 2004 한국 스포츠 리서치 Vol.15 No.3

This study was intended to examine whether the existing player assessment formulas by the sports game factors sufficiently explained/assessed a quality of games for a high reliability between the calculation-relevant parties in calculating a part of sports game results which impacted the sports player assessment, and to investigate why a difference between the sports game results and an evaluative result of player'ss actual value occurred, This analysis assumed that there was a contradiction in the player assessment for the sports game results, Searching how the players assessment has been done so for and what advantages and disadvantages of assessment are, could be a basis for structuring the assessment model. The model for the study analyzed the Power Ranking Formula per position expressed by Sports Cosun (records×(40/total playing time), Rank ER Index of NBA (ER=A-B/total number of athlete play), assessment formula of KBL's player contribution (assessed score of sports game results =extra score per item - deduction per item), NSP/SP formula of Harder, the contribution formula of Sports Chosun (contribution =points +rebound +assist +steal+ block +defense +minutes]-[error =number of failed shootings]), and ATR formula evaluating the point guard (ATR=assist (error), First, 'Sports Chosun' has the meaning of players comparison per position, but cannot do the relative comparison between positions and doesn't provide an exact mathematical information, Second, ER has a similar computing method to the formula of 'Sports Chosun' except that its mathematical information is more concrete. It is not reasonable method to evaluate all players at the same time, Third, KBL's formula accepted a diversity of assessment methods compared with other formulas, There are factors of addition/deduction even in some section, It attempted to carry out the player assessment such as granting the same weight in a concrete way, However, variables which are absolutely necessary for the assessment of underground results and extension of addition/ deduction need to be generated. Also, an objectivity of weight for a removal of voluntary grant is required, Forth, ATR formula evaluates the part of player's ability, but nobody can know whether the results are influenced by any role, Compared with other formulas, this formula is very improper, Fifth the formula of 'Sports Seoul! is almost consistent to the formula that deducts the weight in KBL formula, It is very similar to the KBL formula except an easy calculation of the formula, Consequently, a careful consideration is required, Sixth the formula of Harder seems to have the save context of flow as the formula of KBL and 'Sports Seoul'.

본 연구는 수침 처리가 백삼제품의 원형복원에 미치는 영향을 조사하여 백삼제품 제조에 사용한 원료수삼의 품질을 평가하기 위한 기초자료를 얻고자 수행하였던 바 결과를 요약하면 다음과 같다. 백삼의 수침처리는 원료수삼과 같은 수준으로 원형을 복원할 수 있어 제품에 사용된 원료수삼의 뇌두의 경흔적, 동체부위의 피해정도 그리고 내부조직의 나이테 관찰이 용이하여 연근판별 및 품질평가가 가능하였다. 백삼제품의 ginsenoside 함량은 제조회사에 따라 다소 차이가 있었으며 panaxadiol계 사포닌은 ginsenoside-Rb₁이 많고, panaxatriol계 사포닌은 ginsenoside-Rg₁이 높게 나타났다. 그리고 수침에 의한 백삼의ginsenoside 함량은 수침온도가 증가할수록 감소하는 경향이었다. This study was conducted to investigate the effects of soaking treatment in white ginseng and evaluated quality evaluation of raw ginseng and ginsenoside. Restoration to the original state of the raw ginseng can be achieved by soaking treatment in white ginseng. Stem vestige at rhizome and damage of main root of the swelled white ginseng was examined by eyes and annual rings by microscope easily. Soaking treatment made it easy to be examined the identification of root age and quality evaluation of white ginseng. The content of ginsenoside showed difference among the three products. The content of ginsenoside-Rb1 was highest among the constituents of protopanaxadiol saponin and the content of ginsenoside-Rg1 among that of protopanaxatriol saponin. The higher the soaking temperature was, the lower the content of ginsenoside in the white ginseng was.

영-자기장 분리의 중첩 모델 분석에 의한 루비 내의 불순물 Cr³의 위치 결정

한찬수 순천향대학교 기초과학연구소 1997 순천향자연과학연구 논문집 Vol.3 No.1

The superposition model has been applied to determine the position of substitutional Cr³+ion in ruby under an assumption that the Cr³+ ions occupy a site not far from the Al³+ site. We also assumed that the chromium ions keep the symmetry about the c-axis due to the ESR-spectra. According to the superposition model analysis, we have found that the very Al³+ site(D₁=0.841Å) does not accord with the experimented value D=-5.7427 GHz, whereas the site of D₁=1.300Å along the c-axis does
