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.

강소기업의 지속성장을 위한 경영권 승계 철학

박기찬(Ki-Chan Park),이윤(Yune Lee),이한구(Han-Gu Lee) 피터드러커 소사이어티 2014 창조와 혁신 Vol.7 No.2

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.

한찬호,최덕규 경운대학교 산업기술연구소 2000 産業技術硏究論文誌 Vol.3 No.1(B)

In the AV system, to produce a realistic sound effect is very difficult because the distance between stereo speakers is very narrow. Many signal processing method of widening the sound image for spatial impression have been studied. Most of the typical methods of widening the sound image are related to the phase shifting. but this method was not effective in the concrete wall structure with high reflectivity. In this paper, we proposed an effective method of extending stereo sound image using Precedence Effect and reflected sound. In experiments we confirm the usefulness of the method for extending stereo sound image of a conventional AV system in wider listening area of a room.

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.

한찬수 순천향의학연구소 1995 Journal of Soonchunhyang Medical Science Vol.1 No.1

To compare the geographic differences in anesthesia between Eumsung eup and another city, anesthetic experiences of 8,307 cases performed at the Sunchunhyng Eumsung Hospital from Apr. 1984 to Dec. 1994 were analyzed statistically according to age, sex, physical status, anesthetic agents and methods, emergency operations and medical insurances. There were no inclusions of cases performed under local anesthesia. The results were as follows: 1) According to the age category, 21-30 and 31-40 year age groups occupied 47 % of the total cases. 2) Sexual categorization was as follows: male 47.5 %, female 52.5 %. 3) According to the preoperative A.S.A. physical status, 58.9 % of total cases were class 1. 4) General inhalation anesthesia was performed in 83.3 % of total cases. 5) 41.5 % of the total cases were emergency cases. 6) Medical insurance patients have been increased since 1988.

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 시중에서 거래되고 있는 백삼을 구입하여 수침 처리가 백삼의 원형복원 및 사포닌 성분에 미치는 영향을 구명하고자 수행하였다. 시판백삼은 같은 등급 및 편급의 제품이었으나 뇌두, 근장, 근직경 등 조사 형질에서 제품간 차이가 있었다. 그리고 수침처리에 의해 근중, 동체, 근직경, 근장 등은 증가하여 원료삼으로서 수삼상태를 확인할 수 있었다. 또한 이들 백삼은 온도가 증가할수록 체적이 빨리 증가하여 온도에 의한 영향을 크게 받았으며 다시 건조하여 본래 백삼의 상태로 환원하는 것이 가능하였다. 그리고 수침에 의한 근중의 변화는 2배 이상 증가하였는데 근중이 최고도에 달하는 시간은 대략 24시간 후 이었다. This study was conducted to investigate the effects of soaking treatment in white ginseng and evaluated white ginseng on the restoration to the original shape and the quality of raw ginseng. KW-1 white ginseng had longer rhizome length and main root length. KW-2 had larger rhizome diameter, main root diameter and root weight. KW-3 showed lower quality than the other two white ginseng products. Soaking treatment made the root weight, main root diameter and main root length of raw ginseng increased. The decrease of root weight was significant by drying. The effects of soaking and drying treatment on the characters investigated of the raw ginseng and white ginseng showed same tendency. The higher the soaking temperature was, the faster the increasing rate was. The increasing of white ginseng stopped after around 12 hours from soaking at any soaking temperature.

To invent environmentally friendly materials for packaging of agricultural produce, morphological and mechanical properly changes after daylight exposure and soil deposit for LDPE films composed of different incorporation substances have been investigated. Silver coated ceramic, zinc oxide, fine particle of ferrofluid and pine needle's extract were the incorporated substances. The pine needle's film degrades fast in soil while the silver coated ceramic's film shows daylight decay more on the morphological view. The mechanical strength keeps almost same. But turndown of elongation is explicit on the pine needle's film and silver coated ceramic's film.
