This study was conducted to investigate the eating patterns of Korean men by analyzing the relation among their socio-demographic characteristics, value toward food and nutrition, and eating behavior. Nine hundred twenty nine Korean men were selected by the stratified random sampling method. The socio-demographic characteristics of the subjects had a significant influence on their value toward food and nutrition. After in their sixties had meals for physiological needs rather than for nutrition or preference. Highly educated people, professional workers, office workers and people in the higher incomes, placed a higher value toward food and nutrition. In addition, rural inhabitants had a significantly lower value toward food and nutrition. They mainly ate to satisfy their hunger. The subjects' eating behavior had a significant difference according to their socio-demographic characteristics. The aged and the less educated valued breakfast the most, and showed a preference for rice as the staple food. The rate of skipping meals for this group was low. The higher their income, their eating behavior score was equally high, while the primary industrial workers and rural inhabitants had a low eating behavior score. Value toward food and nutrition had a significant influence on eating behavior. Those that placed a high value toward food and nutrition showed a marked tendency to choose bread or noodles rather than rice. In addition, those who placed a high value on food and nutrition skipped fewer meals and had a higher eating behavior score.

It is well known that the metallo- phthalocyanine (MPcs) are sensitive to toxic gaseous molecules such as NO2 and also chemically and thermally stable, Therefore, lots of MPcs have been studied for the potential chemical sensor for NO2 gas using quartz crystal microbalance(QCM) or electrical conductivity. In this study, ultra-thin films of octa(2-ethylhexyloxy)copper-phthalocyanine were prepared by Langmuir-Blodgett method and characterized by using UV-VIS absortion spectroscopy and ellipsometry. Transfer condition, and characterization of LB films were investigated and preliminary results of current-voltage(I-V) characteristics of these films exposed to NO2 gas as a function of film thickness and temperature were discussed.

Erwinia herbicola(EH) 채소 연부병 방제를 위하여 충북 청원군, 진천군 및 충남 연기군 일원의 채소 경작지 토양으로부터 형광성을 나타내는 Pseudomonas속 1, 196균주를 선발하고, 연부병균 Erwinia herbicola에 대한 생육억제력과 생물학적 검정으로 발병억제력이 강한 2균주를 선발하여 Pseudomonas fluorescens S4(PS4)와 Pseudomonas fluorescens S65 (PS65)로 동정하였다. 배춧잎을 이용하여 분리길항균의 연부병균에 대한 생물학적 억제력을 확인한 결과 상당한 발병억제력을 확인하였다. 이들 두 균주가 가장 높은 길항력을 나타내는 조건은 배양 초기배지의 pH를 7.0으로하여 25℃에서 3일간 배양했을 때였다. 화학농약 및 항생물질에 대해 2균주 모두 benomyl, propamocab hydrochloride, fosethyl-Al-folpet, vancomycin, penicillin 및 lincomycin에 내성을 나타냈고, PS4균주는 erythromycin에 대해서도 내성을 나타냈다.

To find out the optimum mixing level of wheat bran to improve the quality of 1st cut Alfalfa silage, this trial was canied out at two-year's Alfalfa monoculture field of the National Livestock Research Institute, Suwon, Korea, from May 1955 to Oct. 1995.

다결정 (Fe2O3)1-x(In2O3)x (x=0과 0.02)의 자기상 변환을 Mossbauer 분광방법에 의해서 연구하였다. 연구결과 분석은 시료가 각 온도에서 반강자성과 약강자성 두 개의 자기상이 공존한다는 가정하에서 행하였다. x=0 시료에서 온도 변화에 따른 Mossbauer 매개변수의 비정상적인 변화의 원인은 여러인자에 의해서 좌우되지만, x=0 시료와 비교할 때 주된 인자는 결정내의 양이온 자리에 위치하는 Fe3+와 In3+이온의 무질서한 분포로 설명할 수 있다. x=0과 0.02시료와 자기상변환온도를 각각 257±3과 205±3K로 결정하였다.

Spring sown oat crops were grown during early March to late June in 1993~1994. The crops were harvested at different stage of maturity to determine the yield performance, chemical components and net energy value of the plants for silage utilization. The p
