This study was carried out to assess whether feeding of alcohol-fermented feeds (AFF) affects the nutritional metabolism and growth characteristics of Korean native steers. Ten steers were randomly assigned to one of two treatment groups. The dietary treatments were AFF (50% commercial beef cattle feed+30% alcohol-fermented soybean curd dregs+20% rice straw) and control (80% commercial beef cattle feed+20% rice straw). The change of serum metabolites and growth characteristics were measured every two months during the whole twelve months experimental period and the relationships between serum metabolites and growth characteristics were simultaneously analyzed. Four hours after feeding AFF, serum alcohol concentration reached its peak with a significantly higher value than that after control feeding (11.9 and 4.9 mg/dl, respectively). Serum glucose and inorganic phosphorus (IP) concentrations (63.1 and 8.4 mg/dl, respectively) of steers fed AFF were higher than those (56.6 and 7.0 mg/dl) fed the control diet. In both treatments, the serum glucose concentration rapidly increased when body weight (BW) of the steer reached about 600kg, while IP concentrations were rapidly diminished at that BW. Lower concentrations of both blood urea nitrogen (BUN) and cholesterol were observed in steers fed AFF up to 450 kg of BW. The IP concentration was correlated with concentrations of BUN, cholesterol and glucose in AFF fed cattle but not in the cattle fed control diets. Average daily gain was higher in steers fed AFF than steers fed control, particularly during the growing stage of cattle. These findings indicated a capability of AFF to improve BW gain of Korean native steers by decreased protein degradation as well as increased fat synthesis.

현미의 한우에 대한 사료가치 평가를 위해 옥수수 50%와 100%를 현미로 대체한 배합사료의 반추위 발효성상, in situ 영양소 분해율, in vivo 전장소화율을 측정한 바 결과는 다음과 같다. 옥수수와 현미의 체내 영양소 소화율과 영양가는 유사하였으나 반추위 내 분해율은 현미가 옥수수에 비하여 빠르게 나타났다. 옥수수와 현미가 함유된 시험사료를 급여한 후 반추위 pH는 시험사료 간 차이를 보이지 않았으나 NH3-N 농도는 현미 급여수준이 증가할수록 낮아졌다(P<0.05). 반추위액의 총휘발성지방산 함량은 옥수수구가 현미구에 비하여 높게 나타났으며, 초산과 프로피온산 비율(A/P)은 옥수수구에 비해 현미를 급여한 구에서 높은 수치를 보였다(P<0.05).이러한 결과를 볼 때 소 사료에 옥수수를 대체하여 현미를 사용하는 것에 영양학적으로 문제가 되지 않으며, 특히 곡류사료 위주 사양체계 하에서 낮은 초산과 프로피온산 비율에 대한 현미의 긍정적인 효과가 기대되어 이러한 곡류 내 가용성탄수화물의 이용성에 대한 다양한 연구가 수행되어야 할 것으로 사료된다.

Maintenance open spaces and community development in large scale housing development is one of the most important issues. We(UDC) established a resident participation activity for maintenance and use open space with community development in Hachioji New Town from 1997. The purpose of this study is to establish resident participation activities for maintenance and use open space with community development in Hajichioji New Town, and to clarify the characteristics and to on sider about efficiency of the activity. We established Minamino Shizen-Juku as a methodology for maintenance and use open spaces at the same time Hachioji New Town was opened in 1997. The activity has continued by now in 2001. We conducted questionnaire survey to make sure efficiency and characteristics of the activity past three years. Minamino Shizen-Juku (nature friendly lessons) is a resident participation activity in Hachioji New Town. It was established in 1997 as soon as the new town was opened, this year is fifth since it was started. It has three objects. 1)Maintenance and use woody environment, 2) Community development, 3) Continuation and renewal native culture. And it has general course, three special courses and one extra course were established in the activity. 1) General course is an activity participated all of member. It's included farming experience in the native field and seasonal events. 2) Rice growing and woods maintenance course is rice growing and wild wood maintenance in the park as a series of annual farming activities. 3) Benefaction from farm course is started from planting spring vegetable at Mizukoshi(Leader of Minamino Shezen-Juku)'s field. There is the number of participant limit because of the area of the field. 4) Watching nature course is watching seasonal wild flowers, trees, animals and plants to know about native nature. 5) Extra program is programmed to know about native history and tradition. It's planned including participant's ideas. Not member can participate in this course too.

Fifteen varieties of Oryza sativa mainly includig those of Korean native rice were exactly cutted into three layers such as L$_1$ layer (the outer part of 90% from rice center), L$_2$ layer(the part of 81 ~ 91% from the rice center) and L$_3$ layer(the inner part of 80% from the rice center) and ferulic acid derivatives, which play an important role of antioxidative action, were quantitiavely analyzed by UV absorption spectrometric method at fixed 314nm. From this experiment, it was found that the more it enters from the surface into the rice center, the more those secondary metabolites contents were highly reduced. The varieties showing contents more than 20 mg/g were as follows: Hwasunchalbyeo(25.8mg/g), Jojeongdo(24.1mg/g), Suwon425(21.2mg/g), Daigolbyeo(20.6mg/g) and Nonglimna 1(20.2mg/g) by this order. Estimation onthe anthocyanin contents of both Suwon 425 and Sanghehanghyeolna revealed that its total. contents were very exactly close each other. However, it was charateristically differentiated in the contents of L$_2$ layer with respect to showing a considerably higher content of Suwon 425 than of Sanghaehanghyeolna. Conclusively, the selected Suwon 425 variety, which is coloured and flavour volatile one, showed relatively higher contents of anthocyanin, ferulic acid derivatives in the L$_2$ layer as well as L$_1$ layer when compared with Sanghaehangyeolna and even other varieties. This fact suggested that Suwon 425 could be a promising candidate for the development of health rice food.

This research has been conducted to collect regional ecotypes of Poa pratensis throughout the southern part of korean peninsula during 2000~2002. 227 local ecotypes of Poa pratensis were collected mostly from roadsides, riversides and rice paddies. The $35^{\circ}$ latitude was supposed to be the southern limit of native Poa pratensis habitat. 130 ecotypes of Poa pratensis found from the poor environmental condition such as roadsides showed Poa pratensis naturally grew throughout the country. When surveyed the habitat environment, it was concluded that native Poa pratensis were mostly found on open fields or half shaded areas, on sandy soil or sandy loam soil, and in the individual patch type.

The relationship of in vitro starch digestibility and gel strength was investigated at various concentrations (10-30%) of rice cultivars with different amylose contents (27.9, 17.9, and 5.2%). As the rice flour concentration increased, predicted glycemic index decreased, but gel strength increased regardless of amylose contents. Gel strength correlated strongly with amylose content, whereas in vitro starch digestibility was more highly affected by rice flour concentration than by amylose contents. Moreover, the impact of degree of gelatinization on in vitro starch digestibility of high amylose rice was also examined in terms of structural features and rheological properties. The digestion rate of fully gelatinized flour was 1.7 times higher than that of native flour, while the disrupted structure with a different gelatinization degree during starch digestion was visually demonstrated through the X-ray diffraction and molecular distribution analysis. The rice flour changed from an A-type to a V-type pattern and showed difference in crystalline melting. The low molecular weight distribution increased with increasing degree of gelatinization during starch digestion. The apparent viscosity also increased with degree of gelatinization. These results demonstrated that the starch digestibility of rice was more affected by concentration than by amylose content, as well as by the degree of gelatinization due to structural difference.

Two Rice cultivars , a high yield variety of Cheongcheong and a Korea native kind of Chucheong were grown in paddy. 1$\mu\textrm{g}$ and 10$\mu\textrm{g}$ of aflatoxin B1 and Aspergillus flavus (106 conidia/ml) were inoculated at milk stage. At harvest, kernels from the inoculated plant showed slightly lower ripening rates and 100-grain weight than did those of controls. The nutrient and fatty acid composition of unpolished rice of inoculated group were similar to those of controls and difference between the control and inoculated group were not significantly different.
