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.

Chlorobenzens(CBs) and chlorophenols(CPs) in fly asha discharged from several municipal soild waste incinerators (MSWI) were investigated in terms of total content and isomer distribution. The content of CBs and CPs was highest in the fly ash from S incinerator, which were 1040.7ngCB/g-fly ash and 1156.4ngCP/g-fly ash. According to the experimental results, while all samples contained a large amount of the higher chlorinated CBs the amount of lower chlorinated CPs varied with season It was found that the isomer distribution of CBs and CPs was almost constant regardless of season. The quantities of CBs and CPs depended closely on the chemical composition of MSW, while the isomer distribution of CBs and CPs was contant throughout all the year round.

Honeycomb 觸媒에 의한 窒素酸化物과 2-CP의 同時除去에 관한 硏究

李宇根 江原大學校 附設 環境硏究所 1993 環境硏究 Vol.10 No.-

도시폐기물 소각로에서 배출되는 질소산화물과 Dioxin類를 동시에 제거하기 위해서 honeycomb型 觸媒를 이용하여 반응온도 200-400℃의 범위에서 질소산화물과 Dioxin類의 前?物質인 2-CP의 同時除去 실험을 수행하였다. 실험결과에 따르면 space velocity 6000 hr^(-1)과 NH₃/NO_(x)比 0.5에서 90%이상의 NO_(x)제거율이 얻어졌으며 space velocity 1200 hr^(-1)에 2-CP가 거의 완전히 분해됨을 알 수 있었다. 동시제거 실험에서는 공존물질에 의한 제거율의 저하는 없었고 2-CP의 경우 단독 제거보다 동시제거 실험에서의 제거율이 더 높음을 알 수 있었다. The removal of NO_(x) and 2-CP was investigated over the temperature range of 200-400℃ by using a honeycomb catalyst, for the purpose of finding the condition to decompose simultaneously NO_(x) and dioxin. The removal efficiency of NO_(x) was 90% at the space velocity of 6,000 hr^(-1) and NH₃/NO_(x) ratio of 0.5. And the removal efficiency of 2-DP was 99% at the space velocity of 1200 hr^(-1). There was no effect in the removal efficiency of NO_(x) and 2-CP by co-existing materials(NO_(x), NH₃, 2-CP etc.) at the simultaneous decomposition. The removal efficiency of 2-CP in the simultaneous decomposition was higher than in the only decomposition of 2-CP.

Fingerprint patterns of 333 schizophreniacs who met with the diagnostic criterias of International Pilot Study of Schizophrenia except items associated with chronicity in exclusion criteria were studied, and the following results were obtained. 1. The frequency distribution of the fingerprint patterns in the 333 schizophreniacs was ulnar loop, whorl, twinned loop, arch, radial loop in order in both control and schizophrenia groups. 2. Finger ridge counts of both sexes were decreased significantly in schizophrenia group. 3. Dissociation of fingerprint pattern in the schizophrenia group was 51.1%, which was far greater than 6.25% of control group. Number of dissociation was greatest in the thumb, followed by index, middle, ring, and little finger in order. According to the above results, it is considered that both the number of finger ridges and degree of dissociation of fingerprint patterns were closely related with schizophrenia. Analysis of fingerprints and palmprints with the aid of chromosomal analysis would contribute the early diagnosis and prevention of schizophrenia.

Soil properties, relief of field surface, growth information, grain yield were investigated in a 1ha paddy field in 2001 to obtain basic field information for precision agriculture. The field information were analyzed to examine their within field variability using descriptive statistical method. Semivariograms and Kriged maps of geostatistical analysis were also adopted to examine their within field spatial dependence. The results obtained were as follows ; 1) Nutrient distribution difference of available SiO_2 was seemed 14 times overs, 3 times overs at tiller number, 4 times overs at grain yield from within a paddy field. 2) Descriptive statistics of field information showed that the coefficient of variation ranged from 5.45∼51.3%. 3) Field information showed a high spatial dependence within a paddy field. The Q values ranged from 0.24∼1, the ranges of spatial dependence were from 8.1∼50m, respectively. 4) Kriged maps enable the visualization and comparison of the spatial variability of field informaton.

의사결정지원시스템에서 직관적이고 사용자 친숙한 모델 해결을 위한 모델과 솔버의 유연한 통합에 대한 연구

이근우,허순영 한국경영과학회 2005 韓國經營科學會誌 Vol.30 No.1

Research in the decision sciences has continued to develop a variety of mathematical models as well as software tools supporting corporate decision-making. Yet, in spite of their potential usefulness, the models are little used in real-world decision making since the model solution processes are too complex for ordinary users to get accustomed. This paper proposes an intelligent and flexible model-solver integration framework that enables the suer to solve decision problems using multiple models and solvers without having precise knowledge of the model-solution processes. Specifically, for intuitive model-solution, the framework enables a decision support system to suggest the compatible solvers of a model autonomously without direct user intervention and to solve the model by matching the model and solver parameters intelligently without any serious conflicts. Thus, the framework would improve the productivity of institutional model solving tasks by relieving the user from the burden of learning model and solver semantics requiring considerable time and efforts.
