  • Rheological properties of cowpea and mung bean starch gels and pastes were investigated and compared with Instron Universal Testing machine and Brabender Viscometer. As the result of puncture test of gels, yield point force of mung bean starch gel was higher than that of cowpea starch gel. Compression coefficient of cowpea starch gel calculated by Bourne's equation was lower than that of mung bean starch gel. the stress relaxation test showed that viscoelastic properties of cowpea and mung bean starch gels may be represented by six element Maxwell model consisting of three Maxwell element in parallel. Cowpea and mung bean starch pastes showed bingham pseudoplastic behavior in 3, 5, 6, 7 and 8%. The consistency index in 7∼8% of cowpea starch paste were lower than those of mung bean starch paste. concentration dependence on consistency index and yield stress in mung bean starch were higher than those of cowpea starch. The yield stress of starch pastes was significantly correlated with yield point force by puncture test (r=0.996).

  • CORBA에서 객체 기술은 분산 및 이기종 기계에 분산되어 있는 소프트웨어 컴포넌트의 통합된 구현을 용이하게 한다. CORBA와 유사한 객체 통합 기술들은 표준화된 컴포넌트 통합 및 상호 동작 모델을 정하고 호환 불가능한 컴포넌트 구현을 캡슐 화하기 위한 객체지향 원리를 발전시켰다 본 논문에서는 Java Bean에 기반을 둔 분산 시스템 환경에서 객체와 객체간에 관련성을 모델링하기 위해 컴포넌트, 연결자 및 컴포넌트 스키마로 구성된 구조화된 모델을 제시하고 구현한다. 특히 Java Bean 환경에서 객체간의 관련성을 모델링하기 위한 연결자의 구성에 중점을 둔다.

  • Soy protein was isolated from Korean soy bean 'Chang ryub' and chemically modified with succinic anhydride. Functionality of the soy protein isolate(SPI), succinylated SPI(SPPI), and PP590(commercial) at various pH were investigated. The mechanical and sensory properties of soy bean curds made from several mixing ratio of succinylated soy bean milk were observed. The solubility of SPI significantly increased with succinylation. The solubility of PP590 was lower than that of SSPI. The solubility of SPPI increased significantly in 0.03M CaCl2 solution. The emulsifying activity of SSPI increased. On the range of pH above pI the emulsifying activity of PP590 was higher than that of SPI. There was no difference in emulsion stability among the groups. The foam expansion capacity of SPPI increased at higher pH than pI but the foam stability decreased significantly above pH 9. Mechanical texture profile analysis revealed the modified soy bean curds had the lower hardniss, chewiness and cohesiveness with increased modification. The mechanical characteristics of modified soy bean curds revealed generalized Maxwell Model of 7-elements or 5-elements. In sensory evaluation, the hardness, the springiness and acceptability of modified soy bean curds were lower significantly than those of control soy bean curd.

  • Obesity may cause metabolic syndrome and adult diseases. This study was undertaken to investigate the ameliorative or useful effects of beanleaves on inflammation and liver damage in obese rat models. Rats were divided into three groups: a control group (normal diet, n=6), a fat diet group (45%-fat diet, n=7), and a bean leaf group (45%-fat+Korean bean leaves diet, n=7). Body weights in the bean leaf group were lower than those of the fat group (P<0.05). Serum tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and prostaglandin $E_2$ ($PGE_2$) concentrations were lower in both the control and bean leaf groups than in the fat group (P<0.001). TNF-${\alpha}$ concentrations in the bean leaf group were slightly higher than in the control group but statistically significant (P<0.05). The bean leaf group histologically exhibited lower fatty degeneration, spotty necrosis, and leukocyte infiltrations in hepatic tissues than those of the fat group. In the homogenized liver tissues, the cyclooxygenase-2 (COX-2) gene was only expressed in the fat group. The gene expression levels of hepatic TNF-${\alpha}$, inducible nitric-oxide synthase, peroxiome proliferator-activated receptor-${\alpha}$ (PPAR-${\alpha}$), poly (ADP-ribose) polymerase (PARP), and transforming growth factor-${\beta}1$ (TGF-${\beta}1$) were weaker in the bean leaf group than in the fat group. These results suggest that adding bean-leaves to the diet may ameliorate obesity-induced systemic inflammation and liver damage and that bean leaves may be a useful food for preventing obesity and thereby metabolic syndrome and adult diseases.

  • This study aims to examine the consumer preference for packaged bean curd that takes a growing public interest. Specifically, this study tried to examine which is more important - the place of origin of the raw bean or the environmental-friendliness of the raw bean. Surveys were conducted to obtain information, such as the consumer evaluation for food safety on imported food products from China and the consumer perception of Chinese organic food products, Using the binary probit model, the relationship between consumer's choice of packaged bean curd and potentially important factors that can affect the consumer's choice was analyzed. A summary of this research and some policy implications follow. The results of this study can be used as the basic guideline as to how to extend the safety of imported food products, in general, and how to further develop the packaged bean curd industry in Korea, in particular.

  • 시판되고 있는 두류 22 종류의 70% 에탄올 추출물을 제조하여, 이들의 항산화 활성, 화학적 변이원 mitomycin C에 대한 항변이원성, 세포독성, 변이원성 등을 포함하는 생리활성 효과를 비교 검정하였다. DPPH radical에 대한 전자공여능, hydroxy radical 소거능 및 지질 자동산화 억제효과 등은 모든 두류 품종이 거의 유사한 효과를 나타내었다. 예팔, 완두, 녹두, 백편두 등은 변이원 mitomycin C에 대해 유의할만한 수준의 항변이원성을 보였으며, 녹색나물콩, 녹두, 속피리 등은 지시 세포의 성장을 촉진하는 효과가 있었고, 속청과 청태는 변이원성을 억제하는 특성이 있었다. 백편두는 세포 성장과 돌연변이 유발 모두를 억제하는 것으로 나타나 추출물 자체가 독성을 가질 수도 있을 것으로 생각되었다. 결과적으로 본 연구의 목적이었던 기능성 밥 및 떡 제조를 위한 부재료로서의 두류 이용을 위해서는 예팥, 녹두 등을 이용하는 것이 바람직하리라고 생각된다.

  • The purpose of this study was to determine the optimal mixing conditions of different amounts of Jinuni beans and fresh cream for the preparation of Jinuni bean chocolate. An experiment was designed using the central composite design of the response surface, which required 10 experimental treatments including 2 replicates for the Jinuni bean and fresh cream. The compositional and functional properties of the treatments were measured and these values were applied to the mathematical model. A canonical form and perturbation plot showed the influence of each ingredient on the mixture products. The color value L (Lightness) decreased with an increase in the amount of added Jinuni bean but the color value a (redness) and color value b (yellowness) did not change. In addition, the hardness value increased with the addition of the Jinuni bean. The results of the sensory evaluation showed very significant differences in the values of the texture (p<0.01), taste (p<0.05), and overall quality (p<0.01). As a result, the optimum formulations as determined by the numerical and graphical methods were 27.98 g of Jinuni bean and 67.0 g of fresh cream.
