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.

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.

Polymer-Impregnated Concrete(PIC) is a new polymer-concrete composite material which consists of basic cement concrete and polymer. The mechanical properties and behavior of PIC depend on the type of polymers and the impregnation techniques. In general, the polymer impregnation can improve the strength, durability and ductility of normal concrete. The objective of this study is to develop the analytical procedure for analyzing the structural responses of polymer-impregnated concrete flexural members with different polymer loading by using finite element method on the basis of experimental results.

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.

소각장별 비산재 중의 중금속 용출 특성 및 존재형태

이우근,김준수,김진범 江原大學校 附設 環境硏究所 1998 環境硏究 Vol.15 No.-

본 연구는 도시폐기물 소각시설에서 발생되는 비산재 중에 함유된 중금속으 존재형태 및 용출 툭성을 알아보기 위해 수행되었다. 용출 실험은 KSLT, TCLP, MALT법을 이용하였고 중금속의 존재형태별 분포에는 다음과 같이 5가지 형태로 구분하였다.; exchangeable, carbonate, reducible, organic, residual fraction.용출 심험 결과에 의하면 pH 4로 일정하게 유지한MALT법에 의한 중금속 용출량이 가장 높 This study was carried out to estimate the fractional composition and leaching properties of heavy metals in fly ash generated from three municipal solid waste incinerators(MSWI). Three leaching tests are used in this work. These are Korea Standard Leaching Test(KSLT)), Toxicity Characteristic Leaching Procedure (TCLP), Maximum Availability Leaching Test(MALT) method. The fractional composition of heavy metals is classified into five fractions; exchangeable, carbonate, reducible, organic, residual fraction. According to the leaching tests, it seems that the highest amounts of heavy metals are leached by MALT method in which pH of 4.0 maintains constantly. From the results of the fractional composition of heavy metals, above 45% of Cd is leached by the change of pH or/and concentrations at I and J incinerators. And 91% of Cd is extracted under the reducible environment at B incinerator. But Cu may be leached under the strong acidic environment. The amount of Cu at B incinerator is less leached than that of I and J incinerators due to high residual fraction. About 35% of Ni in fly ashes at three incinerators exists in reducible fraction. It is probably leached under the reducible environment. Pb may be leached under the weak acidic environment at I and J incinerators, but in case of S incinerator leached under the strong acidic environment.

논에 있어서 정밀농업을 위한 기초자료수집과 분석을 하기 위해서 토양의 특성, 포장면 고저차, 생육상태 그리고 수량에 관한 포장정보를 조사한 결과 아래와 같은 결과를 얻었다. 가. 기본통계값을 살펴보면 유효태 규산의 경우는 한 포장내 14배 이상의 변이차이를 보였으며, 생육정보 중 분얼수는 3배, 수량은 4배 이상의 차이를 보였다. 나. 포장정보의 변이계수를 살펴보면 5.45∼51.3%의 공간변이를 보였다. 토양특성 중에 pH를 제외한 나머지가 10%이상의 공간변이를 보였다. 포장면 고저차는 51.3%, 생육정보는 7.32∼23.2%, 그리고 수량에 있어서도 변이계수가 22.5%를 보였다. 다. 포장정보를 공간통계학을 이용해 해석한 결과, 포장정보의 공간구조 발달여부를 표시하는 Q값이 0.24∼1로서 공간구조가 포장정보에 따라서 발달되어 있었으며, 공간변이의 의존거리를 나타내는 랜지는 8.1∼147.9m를 보였다. 그러나, 실질적인 랜지는 토양특성값이 15∼50m 정도, 생육정보는 15m 전후, 포장면 고저차는 30m 정도, 수량은 8.1m를 보였다. 이것을 기초로 하여 크리깅 방법으로 데이터를 보간하여 지도화 시킨결과, 공간변이를 이해하는데 유용하게 이용될 수 있는 포장정보 지도를 얻을 수 있었다. 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.

Earth Anchor의 인발저항력에 관한 연구

이유근,김우중,윤용철 진주산업대학교 1994 論文集 Vol.33 No.-

This paper describes the results of an experimental consideration on the uplift capacity of the earth anchor. The earth anchor used in pull-out test is the cylindrical steel with plate and eight earth pressure cells(No.1~No.8). The plate diameter is 120㎜ and embedment ratios(L/B; L=length of embedment, B=diameter) are 1, 2 or 3, Also, we investigated surface displacement of the test ground using two gap sensors. Pull-out test were conducted for dry sand of soil placed at a density of loose. From the results, the following conclusions were drawn ; Uplift capacity of anchor becomes larger due to the increase in the L/B. The earth pressure act upon the upside of the anchor plate is different in according to place of earth pressure cell and L/B. That is to say, the earth pressure of No.1 or No.2 (earth pressure cell) increases as time goes by until the anchor pull-out completely, but the earth pressure of No.3(L/B≤2) becomes smaller No.1 and No.2 after the rate of increase of the earth pressure decreased by boundary a point of time. The intersecting point of the ground(sand) surface and the end of shear bed is about 15㎝(L/B=1), 21㎝(L/B=2) or 27㎝(L/B=3) by distance from anchor center.
