본 연구에서는 국내에서 반추가축에게 주로 이용되는 조 사료원들의 영양소 함량 및 반추위 in situ 소실율을 평가 하기 위해서 수행하였다. 착유우 30두 이상의 50여개 농가 를 대상으로 조사한 결과를 토대로 선정한 12종류의 조사 료를 다양한 수입원을 고려하여 확보한 다음, 주요 영양소 성분과 미네랄을 분석하였다. 또한 그 중 5개의 조사료원 (티모시, 알팔파펠렛, 볏짚, 클라인글라스 및 톨페스큐)을 선정하여 반추위 cannula가 장착된 거세 한우 2두(평균체 중 526 ± 14 kg)를 이용하여 반추위 in-situ 소실율을 평가하 였다. 조사한 조사료원들의 영양소 함량은 한국표준사료성 분분석표에 비하여 전반적으로 낮은 함량을 나타내었다. 최종 반추위 in-situ 건물 소실율은 클라인글라스가 가장 높 게 나타났으며 티모시, 알팔파 펠렛, 톨 페스큐, 볏짚 순으 로 낮아졌다. 최종 조단백질 소실율은 알팔파 펠렛이 가장 높았으며 클라인 글라스, 티모시, 톨페스큐, 볏짚 순으로 높게 나타났다.

본 연구에서는 인체 상 하체에 대한 적정 의복압값과 평소 착용습관에 따른 주관적 압박감의 차이를 알아보기 위해 30-40대 중년여성을 대상으로 거들과 웨이스트 니퍼를 착용한 후 압력값과 주관적 압박감을 측정하였다. 또한 화운데이션 착용 시 주관적 압박감에 영향을 미치는 제반 요소(자세변화, 착용시간, 심호흡 등)에 대하여 알아보고자 의복압과 주관적 압박감를 측정하고 분석하여 다음과 같은 결론을 얻었다. 적정 의복압의 평균 결과 거들은 2.1±0.8 kPa, 웨이스트 니퍼는 1.5±0.8 kPa로 하체의 적정 평균 의복압이 상체에 비하여 높게 나타났으며, 하체보다는 상체에서 평소 느슨하게 입을수록 압박 수준에 대한 민감도가 컸다. 화운데이션 착용습관 조사를 통해 느슨하게 입는 그룹을 'loosely', 조여입는 그룹을 'tightly'로 분류하여 압력값과 주관적 평가의 상관관계를 살펴본 결과 'loosely' 그룹에서 객관적 압력값과 주관적 평가 간에 또한 주관적 평가와 선호도 간에 상관계수가 더 높게 나타나 평소의 착용습관이 압박감각에 영향을 미침을 알 수 있었다. 자세(선 자세, 앉은 자세)에 따른 압력값의 변화는 웨이스트 니퍼에서만 유의한 차이가 나타나(p=.001), 웨이스트 니퍼 설계 시 적정 의복압을 유지하기 위한 주의를 거들보다 더 기울여야 함을 알 수 있었다. 또한, 시간이 지남에 따라 실제 압력값은 변화가 없었으나 주관적 압박감은 대체적으로 적응을 하여 장기간 착용 시 생리적으로 부정적 영향을 미쳐도 인식하지 못할 수 있음을 알 수 있다.

This study was conducted to investigate the effects of brown rice and brown rice phytosterol on blood pressure and lipid levels in spontaneously hypertension rats (SHR). SHR were grouped according to blood pressure and fed either a control diet or experimental diets containing 50% brown rice powder or 5% brown rice phytosterol for 3 weeks. Body weight gain and epididymal fat weight were significantly reduced in the brown rice powder and brown rice phytosterol groups compared to control. Brown rice and brown rice phytosterol diets suppressed age-dependent increases in systolic blood pressure compared to control. In addition, brown rice and brown rice phytosterol diets decreased total lipid, triglyceride, and cholesterol levels in the liver, whereas serum HDL cholesterol increased. Lastly, brown rice phytosterol reduced TBARS contents in the kidney. These results suggest that brown rice and brown rice phytosterol exert antihypertensive effects that improve lipid metabolism in SHR.

The purpose of this study was to develop children-friendly education materials based on food replicas for the dietary education of lower grade elementary students. Through a literature review on current dietary problems and dietary education for children, five education themes were chosen: balanced diet, seasonal food, traditional food, noodle culture, and making instant noodles. A total of 304 key food items for food replicas were selected based on the themes: six basic food groups (113 items), balanced meals (37 items), dietary habits (74 items), spring foods (13 items), summer foods (17 items), autumn foods (16 items), winter foods (11 items), Korean traditional foods (52 items), Korean native noodles (18 items), noodles from foreign countries (19 items), and making instant noodles (46 items). Next, a food replica database was developed consisting of name of the food, picture, size, ingredient, recipe, reference, and attached code. Powerpoint slides and teaching plans for all education themes were developed utilizing the food replicas in order to raise interest and understanding of serving size and intake amount. This research provides a basis for the development of food replicas as effective dietary education materials for elementary students and their use in extra-curricular activities, after school programs, community health centers, or food companies.

This study was conducted to investigate the physicochemical properties of the ethanol extracts and soluble dietary fiber from Cassia tora L. seed. The proximate composition of Cassia tora, soluble solid contents, color intensity and contents of emodin and rhein of Cassia tora extract, molecular mass distribution, sugar contents and viscosity of soluble fiber from Cassia tora were analyzed. Cassia tora contains 12.6% of moisture, 5.2% of ash, 13.4% of crude protein, 7.2% of crude fat, 8.8% of insoluble fiber and 48.3% of soluble fiber. The effects of extract condition on soluble solid contents, color intensity and contents of emodin and rhein of Cassia tora extract were investigated. The soluble solid contents were higher in 70% or 50% ethanol extracts than those in 100% ethanol extracts and showed highest value in grind sample extracts. In Hunter's color value, 100% ethanol extracts and whole Cassia tora sample extracts were higher in L and b value, but on the contrary, were lower in a value, than those of the other. The highest emodin and rhein contents were observed in 70% and 50% ethanol extracts, respectively, and showed higher value in room temperature extracts than in heating extracts. The molecular mass of soluble fiber from Cassia tora seed was estimated by gel filtration chromatography. Most soluble fiber(80%) exhibited a molecular mass range of between 50～2000 kDa. The major sugars of soluble fiber from Cassia tora seed were identified as xylose, mannose and galactose. The apparent viscosity of 0.5% soluble fiber from Cassia tora seed was 33 mPas showing a higher value than pectin or xanthan gum.

This study was performed to evaluate the biological activity and protective effect of Cassia tora ethanol extracts against D-galactosamine induced hepatotoxicity in rats. Male Sprague-Dawley rats were grouped into normal group, D-galactosamine treated group(control), D-galactosamine plus 0.25% Cassia tora extracts treated group and D-galactosamine plus 0.5% Cassia tora extracts treated group. Normal and control group were fed control diet and Cassia tora extracts treated groups were fed experimental diets containing 0.25% or 0.5% Cassia tora ethanol extracts for 5 weeks. Body weight gain and liver weight of rats were not significantly different between groups. Cholesterol and triglyceride concentrations in serum and liver were significantly lower in rats treated only with D-galactosamine compared to normal group, and improved in Cassia tora extracts supplemented rats. D-galactosamine treatment significantly increased serum aspartate transaminase, alanine transaminase, gamma glutamyl transferase and alkaline phosphatase, however, the activities of aspartate transaminase and alanine transaminase were significantly decreased in Cassia tora extracts supplemented rats when compared with D-galactosamine treated control group. Cassia tora extracts significantly suppressed the D-galactosamine-induced elevation of liver thiobarbituric acid reactive substances(TBARS) contents. Superoxide dismutase activity was decreased by D-galactosamine treatment, however by the supplementation of Cassia tora ethanol extracts, significantly increased in dose-dependent manner. Glutathione peroxidase activity in rats fed diets containing Cassia tora extracts was decreased compared to control. Based on these results, we concluded that Cassia tora ethanol extracts may prevents the D-galactosamine-induced hepatotoxicity probably via an antioxidant mechanism.

This study was conducted to investigate the effects of Takju lees hot water extracts on the blood pressure in spontaneously hypertension rats (SHR). Twenty eight male SHR were grouped by their blood pressure and fed a control diet or experimental diets containing 1% (G1), 2% (G2), or 4% (G4) Takju lees extracts for 4 weeks. Food intake was not significantly different among the groups. However, body weight gain was significantly lower in groups fed the Takju lees extract than the control group. The systolic blood pressure was significantly lower in the Takju lees extract containing groups (especially in G4 group) than the control groups. In addition, mean blood pressure {(systolic+dyastolic)/2} decreased with an increase in the amount of Takju lees extract in the diet and feeding period. Takju lees extract decreased angiotensin I converting enzyme (ACE) activity in a dose-dependent manner. These results suggest that the Takju lees extract exert an antihypertensive effect by decreasing ACE activity.

We investigated the effect of Takju lees extract on blood glucose levels in the db/db mice (a murine model of type 2 diabetes mellitus). We fed 40 male db/db mice a control diet (G0, AIN93G) and experimental diets containing 1% (G1), 2% (G2), or 4% (G4) Takju lees extract for 4 weeks. We found no difference in food intake and body weight gain among the animal groups. In the G1 and G2 groups, plasma glucose levels decreased significantly between Days 10 and 21 compared with the G0 group. However, we found no difference in plasma glucose levels between groups G4 and G0. The change in insulin concentrations was not significant among these animal groups, and we found no significant difference in glucose transporter 4 (GLUT4) expression in the soleus muscle. These results suggest that the Takju lees extract has a beneficial effect in animals with type 2 diabetes.

Takju lees extract is expected to be a promising material for functional food.
