In this study, we aimed to develop a fermented green rice beverage with a unique flavor and physiological function activity. With glutinous green rice and rice nuruk as independent variables, we modeled the antioxidant characteristics and α-glucosidase, α-amylase inhibitory activity of glutinous green rice fermented beverage to verify its significance. The total flavonoid content and α-glucosidase inhibitory activity were selected as Quadratic models, and DPPH radical scavenging ability and α-amylase inhibitory activity were selected as linear models. For the sensory characteristics of glutinous green rice fermented beverage, sweetness, sourness, savory taste, bitterness, throat feel, nuruk scent, and overall preference increased in preference as the amount of glutinous green rice and rice nuruk increased, but significantly decreased after the center point (p<0.01). A blending ratio of 180.00 g of glutinous green rice and 400.00 g of rice nuruk had the highest preference among all the sensory items. Based on these results, we developed a green rice fermented beverage with unique flavor and physiological function activity of rice using glutinous green rice and rice nuruk, and the optimal blending ratio was determined to be 164.04 g of white rice, 195.96 g of glutinous green rice, and 414.61 g of rice nuruk.

To classify the physiological activity by habitat and part of Dandelion (Taraxacum officinale), antioxidative and antimicrobial activities were investigated from methanol extracts of Dandelion. Dandelion was taken from Uiryeong (in Kyungnam province) and from Seoul, and antioxidative and antimicrobial activities were measured for three different parts of the dandelion: the flower, leaf and root. Antioxidative activities of methanol extracts from Dandelion were examined by a DPPH test, and antimicrobial activities were examined against 5 microorganisms: Bacillus subtilis and Bacillus cereus as G(+) microorganisms, and Salmonella typhimurium, Staphylococcus aureus and Eschrichia coli as G(-) microorganisms. No significant differences were found in terms of antioxidative and antimicrobial activities between the dandelions in Uiryeong and the dandelions in Seoul. Antioxidative activity, however, was higher in the flower of the dandelion, irrespective of habitat. Further research with other physiological factors (besides antioxidative and antimicrobial activities) is necessary to shed light on dandelion physiological function and to enhance the utilization of dandelion.

We investigated the structure-activity relationships on use of multi-layer neural networks. The relationships are techniques required in developments of medicines. Since many kinds of observations might be adopted on the techniques, we discussed some points between the observations and the properties of multi-layer neural networks. In the structure-activity relationships, an important property is not that standard deviations are nearly equal to zero for observed physiological activity, but prediction ability for unknown medicines. Since we adopted non-linear approximation, the function to represent the activity can be defined by observations; therefore, we believe that the standard deviations have not significance. The function was examined by "leave-one-out" method, which was originally introduced for the multi-regression analysis. In the linear approximation, the examination is significance, however, we believe that the method is inappropriate in case of nonlinear fitting as neural networks; therefore, we derived a new index fer the relationships from the differential of information propagation in the neural network. By using the index, we discussed physiological activity of an anti-cancer medicine, Mitomycine derivatives. The neuro-computing suggests that there is no direction to extend the anti-cancer activity of Mitomycine, which is close to the trend of anticancer developing.

Sesame seed are one of the oldest oil-bearing crops known to man. Not only are they nutritious, they are physicologically beneficial. Because of these properties, the promotion of sesame as a crop is set to increase from now on. The lignan component of sesame, which has an antioxidative function, varies considerably. In addition, the seeds remain viable for longer than other crops. At low temperature, it has been reported that the seed remain viable for up to thirty years. This is due to the lignan content of the seeds. In the last twenty years, the mysteries of the natural chemistry of sesame seeds have been unravelled one by one. Up to now, the lignan component has been found to have an $\alpha$-tocopherol synergist effect, an anti-aging effect, a cancer suppressing effect, a hypertension reduction effect, an effect on the promotion of liver function, an effect on the control of the ration of unsaturated fat, and an effect on the synthesis of unsaturated fatty acids. The lignan component of sesame does not simply have an anti-oxidant function, but has diverse recently discovered physiological uses which make the study of lignan highly rewarding.

The effect of compression wear for sport performance and muscle function was investigated based on the physiological test and electromyograph(EMG). The EMG test was used to study muscle activity after fitting the compression wear during exercise. It showed slight difference between men and women testee groups in the results of anaerobic, aerobic, fatigue, and EMG test due to muscle content in the body. In addition, the exercise performance was increased to some extent even the muscle activity was decreased. It is estimated that the compression effect to muscle by the compression wear decreased the muscle vibration and improved blood circulation which helped the entire sport performance. However, it is necessary to study the effect of compression wear in long-term wearing in the future study.

In order to evaluate the antimicrobial function of natural herb extracts as antimicrobial agent or packaging material for the preservation of foods and greenhouse produce, the water extract of chopi (Zanthoxylum piperitum DC.) was prepared and its antimicobial activity was determined. In the paper disk test its antimicrobial activity was increased in proportion to its concentraion. The growth of microorganisms was completely inhibited above 500ppm of its concentration. It showed wide spectrum of thermal(40 to 180oC) and pH(4 to 10) stabilities. In the electronic microscopic observation(TEM and SEM) of microbial morphological change it showed to decrease the activation of physiological enzymes and to lose the function of cell membranes. Even in the activation test of galactosidase, it seemed to weaken the osmotic function of cell membranes remarkably in comparison with chloroform and its activation corresponded to 40~50% of toluene. Zanthoxylum piperitum DC. extract seemed to be an excellent antimicrobial for the inhibition of food borne microorganisms as well as the pre servation of greenhouse produces.

Cyclooxygenase (COX) is an enzyme, which catalyzes the production of prostaglandins from arachi-donic acid and exists in two isoforms (COX-1 and COX-2). COX-1 is involved in the maintenance of physiological functions such as platelet aggregation, cytoprotection in the stomach and maintenance of normal kidney function. COX-2 is induced significantly in vivo under inflammatory conditions. COX-1 and COX-2 serve different physiological and pathological functions. All commercially available nonsteroidal antiinflammatory drugs (NSAIDS) are inhibitors of both COX-1 and COX-2. Therefore, selective inhibitors of COX-2 may be effective antiinflammatory agents without the ulcerogenic effects associated with current NSAms. Since the mid 1990s, a number of reports have been appeared on the preparation and biological activity of selective COX-2 inhibitors. Recently celecoxib, and rofecoxib, the representative COX-2 inhibitors, are introduced in the drug market. In this paper the relationship of structure-activity for selective COX-2 inhibitors is reviewed.
