표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

ABSTRACTAn Influence of Travel Agency's Culture on Organizational Effectiveness Sun-Hee Lee·Yong-Keun Lee The Effects of corporate culture on the organizational effectiveness and/or corporate competitiveness have been widely recognized and discussed among both the incumbent managerial and the academicians of economics and sociology in recent years. The purpose of this study is to review the functions of the corporate culture and to examine the factors of the corporate culture among the travel agencies.The present study starts with a conceptual review of the corporate culture. The characteristics of corporate culture is shaped usually with the two major elements; the styles of management and decision-making of the top managerial and the subculture of the employees. Each of the four components of Corporate culture is operationalized as follows; ① tough-guy, macho culture, ② work hard, play hard culture, ③ bet-your-company culture, ④ process culture. These four components of corporate culture become the independent variables while the recognition of environment becomes the dependent variables in the analytical model proposed in this paper. The recognition of environment such as danger and feed-back speed is divided into pre-IMF and post-IMF.Some results of the findings are as follows: First, before IMF, as the danger is recognized low and feed-back speed fast, the corporate culture is shown as work hard, play hard culture. Second, after IMF, as the danger is recognized high and feed-back speed fast, the corporate culture is shown as tough-guy, macho culture.

퍼지 추론을 이용한 필기체 한글 문자 유형 분류

이근수,윤선희 안성산업대학교 1995 論文集 Vol.27 No.-

본 논문은 인쇄체 한글 입력 문자에 대한 유형을 분류하기 위한 퍼지 추론 방법을 제안한다. 또한 입력 문자에 대한 특징을 추출하기 위하여 최대 길이 투영(Maximum Run Length Projection) 방법을 사용한다. 최대 길이 투영 방법은 잡음에 강하며, 필요한 정보를 가능한 정확하고 효율적으로 추출하는데 유용하다. 한글 문자는 그 양이 방대하고 그 구조가 복잡하며 문자들 사이에 밀접한 유사성이 있다. 따라서 본 논문에서는 추출된 특징들에 대한 퍼지 추론을 적용하여 유형 분류율의 향상을 도모하였다. 사용 빈도수가 높은 인쇄체 한글 문자 917자에 대하여 실험한 결과 98.58%의 분류율을 얻었다. The purpose of this paper is to classify the types of input characters, printed Hangul characters, using fuzzy reasoning. This paper utilizes Maximum Run Length Projection in the extract features of input character. Because the number of Hangul characters is large and its structure is complex, there exists close similarities among characters. This paper, therefore, tried to increment the type classification rate using fuzzy reasoning. The Maximum Run Length Projection is very immune to noise, and also useful to extracting the demanding information efficiently. In a test case with the most frequently used 917 printed Hangul characters, it achieved 98.58% correct classification rate.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

Previous stochastic cost-volume-profit(CVP) models have assumed that price and costs were known with certainty. Subsequently this assumption was relaxed, and CVP models were extended to incorporate uncertainty in price and costs. This paper expands on prior discussions of the mean, the variamce and the contribution margin per unit of each product. As the result of using Beta distribution to estimate of random variable's variance, it is proved to have generalization than traditional method when the variance has large value.

Studies were conducted to investigate the effect of Lasso [Alachlor: 2-Chloro-2'6'-dimethyl-N-(methoxymethyl) acetanilied]on mulched and nonmulched hot pepper filed. Lasso treatment greatly inhibited weed growth and the granular formulation was more effective than emusifiable concentrate in controlling weed growth in both mulched and nonmulched plots. Lasso effect was not apparent about 50 days after treatment. The growth of pepper plant was greatly promoted by mulching and yield of green peppers was more than doubled by transparent polyethylene film mulching. There was no plant in the entire plot which showed apparent phytotoxicity by Lasso treatment.

노인 가계지출구조 분석을 통한 집단 내 이질성에 대한 연구

본 연구는 노인의 가계지출구조를 통해 노인가계의 집단의 특성을 분석하고 이를 통해 집단내의 이질성을 탐색하는 데에 목적이 있다. 우리 나라의 노인문제나 그에 대한 문제 의식은 근대화의 속도만큼이나 빠르게 진행되고 있다. 이에 따라 노인에 대한 많은 연구들이 이루어지고 있으며, 노인집단의 특성별 차이를 부분적으로 다루어 분석한 연구들은 더러 있으나 노인집단 내에서의 이질성에 초점을 맞추어 분석한 연구는 전무한 실정이다. 이에 본 연구는 통계청의 1999년도 도시가계조사 원자료를 통해 노인을 여러 집단으로 나누어 이들의 가계지출패턴이라는 분석 틀을 이용해 각 집단의 특징을 유형별로 분석하였다. 그 결과 전반적으로 집단별로 분석해도 일관적으로 나타난 것은 식료품비와 주거비의 비중이 높다는 것이다. 즉 소비지출에서 식료품비가 차지하는 비율로 측정되는 엥겔계수가 높아 생활수준은 전반적으로 낮다고 볼 수 있다. 다음으로 노인의 특징에 따른 집단을 구분하여 살펴보면, 비록 소비지출액수의 다소에 따른 가계지출 패턴에서는 큰 차이를 나타내지 않았지만, 건강상태와 취업상태에 따라서는 차이를 나타냈다. 이러한 결과는 노인가계의 유형을 다양화하는 작업이 필요함을 시사하는 것이라 하겠다. 그럼으로써 노인이 동질적인 집단이라는 인식변화에 도움이 될 것이라 사료된다. 더욱이 노인에게 서비스를 제공하는 이들에게도 이들의 생활양식에 맞는 다양하고 구체적인 정책적 활용방안을 보여줄 수 있을 것이다. The purpose of this study is investigation about the heterogeneous characteristics of the elderly group through analysis of the household expenditure between the elderly. Korean elderly problem and a critical mind about it is progressing as rapid as modernization speed. Till now many study were accomplished, but there is not the study about heterogeneity between the elderly group. Therefore this study is analyzed out heterogeneous characteristics the elderly only using. Income and Expenditure Survey, national data by NSO(National Statistical Office). Final result is as follow. It is large proportion of food expenditure and house expenditure. Because Engel Coefficient(proportion of food expenditure) means level of living, that means the living of the elderly only is not so good. Next, according to not the consumption level but the condition of health and employment, household expenditure pattern is different result. This result means that there is different living pattern. And it is necessary of different and proper service through the patternization of the elderly. This will be of use to change a fixed idea about the elderly and to offer policy suggestions to service provider ton the elderly.

To identify the clinical characteristics and sleep parameter of sleep apnea syndrome, author performed for statistical analysis of polysomnographic findings of 31 cases, were diagnosed as sleep apnea syndrome from December, 1993 to June, 1995. The results were summarized as follows. 1) Male were predominantly more (M:F=14.5:1) and subject's mean age 41.0±10.7 years. All subjects were obstructive type sleep apnea syndrome, and diastolic blood pressure have met the criteria for hypertension, and that many subjects had ECG abnormality finding. 2) Significant correlations were found among various polysomnographic variables. Respiration disturbance index (RDI) correlated significantly with sleep period during oxygen saturation below 85%, episodes of waking, duration of waking, episodes of obstructive apnea, and episodes of obstructive apnea with heart rate drop & oxygen saturation drop. Same results showed when comparison of two groups were divided by median value of RDI. Sleep period during oxygen saturation below 85% was especially important to select in more severe apnea patients. Also the more episode was apnea, the more episode was waking and time of waking. 3) Sleep apnea episodes during REM sleep were as sleep apnea episodes during NREM sleep, but apnea episodes during REM sleep were more longer time apnea episodes during NREM sleep. This result explain that sleep apnea episode of REM sleep was more adverse effect to cardiovascular system. 4) Subjects with obstructive sleep apnea syndrome had central and mixed type apneas too, and hypopneas with oxygen saturation drop were relatively more that central and mixed type apnea, therefore author thought, when diagnoses of sleep apnea syndrome, hypopnea episode should be considered for more specific diagnoses.
