  • This research was accomplished to prove that the actual using conditions of the funtional bakery products would be different by their sex, age group and income, and what would be main factor to choose them. This survey was examened for 268 subjects by the self-administered questionnaire method. 37% of subjects used the funtional bakery products once or twice a week. They normally paid for them 1,000-3,000 won(40%). The biggest merit of the fuctional bakey products was good for health, but high price was the weekest point of them. Over 63% of subjects answered they had the will to use the new functinal bakery products if they would be developed. Mainly they got the information of functional procuts in bakery. Females paid more than males to buy them and had stronger will to use the new procuts. As the age increased, the using frequency of fuctional bakery products also increased. The expences to buy for them once and the will to use new products increased according to income increment. Females thought more important factors as price, taste, and color than males. Twenties and forties answered price was more important than thirties and fifties.

  • The effects of three different irrigating water qualities(clean water, life sewage and animal sewage) on the pattern of arthropod communities in the rice fields were investigated at Banwol, Kyonggi-do, mid-western part of Korea from 1994 to 1996. The total density of arthropod was highest in the rice field which was irrigated with clean water(clean water field), and the arthropod community was mainly composed of aphids and collembolans. Each functional group was found in the order of 'pests>non-pests>natural enemies' in its density. The dominant taxa in the pest group were aphids, planthoppers(Delphacidae), leafhoppers(Cicadelidae) and rice water weevil(L. oryzophilus). In the non-pest group collembolans, non-biting midges and dipterans were main arthropods, and in the natural enemy group Araneae was the dominant taxon. In the early growth stage of rice plant the dominant functional group was pests, and in the mid growth stage both the pest and the natural enemy group became dominant. But in the late growth stage none of the functional group was dominant over the other functional groups. The densities of spiders were much more higher in the clean water field than in the other fields. And through all the growth stages of rice plants the density of spiders in clean water field kept increase in contrast to the others. The species composition of spiders in the life sewage field was similar to that in the animal sewage field, but in the clean water field it was different from the other two fields.

  • Purpose : This study was performed to examine the effect of stimulation task-oriented training on the balance ability of the hemiplegic patients caused by stroke. Methods : We made a random sampling of 25 hemiplegic patients caused by stroke. 10 patients(experimental group)were treated by simulation Task-oriented training and Conventional training used by balance pad. The other 10 patients(control group) were only treated by Conventional training used by balance pad. During the training, 3 patients from the experimental group and 2 patients from the control group were excluded by private affairs. The control group has done Conventional training 6 times a week for 6 weeks. And experimental group has done Simulation task-oriented training two times, conventional training four times a week for 6 weeks. Balance ability was assessed by Fuctional Reaching Test (FRT) : unilateral and bilateral reaching. Results : In comparison of FRT before and after training, two groups all was significantly improved(p<.05). But bilateral reaching variation was significantly improved in experimental group. Conclusion : we can use simulation Task-oriented training valuably to increase balance ability of hemiplegic patients.

  • The reduction rate of borohydride exchange resin (BER) was greatly enhanced in the presence of lithium salts. Thus 2-heptanone was reduced completely with BER-LiCl in 1 h at room temperature. However, no reduction was observed with BER alone under the same conditions. With this system, organic compounds containing various fuctional groups were examined in ethanol at room temperature. This study revealed that BER-LiCl system exhibits an excellent chemoselectivity for carbonyl group in the presence of other functional groups. Keto esters and epoxy ketones were reduced with BER-LiCl to give the corresponding hydroxy esters and epoxy alcohols with excellent yields. Selective reductions of carbonyl groups were also possible in the presence of other organic compounds containing functional groups such as 1-idooctane, 1-bromooctane, caproamide, hexanenitrile, nitrobenzene, n-butyl disulfide, dimethyl sulfoxide and 1-dodecene.

  • The content of $N^{\varepsilon}$-(carboxymethyl)lysine (CML), an advanced glycation endproduct, in stir-fried anchovy prepared under different cooking conditions was determined, along with their sensory properties. The aim of the study was to optimize cooking conditions of stir-fried anchovy for minimal CML production by using different sugars, sugar concentrations, pH levels, and cooking times. The results showed that CML content increased with increasing sugar concentration. Cooking time did not affect CML content but lowering the pH with lemon juice decreased it significantly. The CML content of samples with a high sugar concentration, and without lemon juice was $4.67{\mu}g/mL$, and that of samples with both a low sugar concentration and lemon juice was $2.49{\mu}g/mL$, indicating a 47% reduction in the CML content of sir-fried anchovy. We conclude that stir-fried anchovy cooked with less sugar and the addition of lemon juice can reduce CML content while maintaining sensory characteristics.

  • Dispersion behavior was investigated as functions of species and arrount of addtives, binders, abrasives, lubricants, etc.. Dispersibilityand other various properties were affected by the fuctional groups of binders. Friction coefficient and surface roughness of tape were changed with lubricants, therefore duratility of magnetic tape was varied. As a result of above investigations, we concluded that dispersion behavior of particles was very sensitive for obtaining maximum properties of metal particle tape.

  • 1. Introduction : Among many azeotropic compounds, pyridine which forms an azeotropic mixture with three moles of water boiling at 92-93$\circ$C is very useful synthetic intermediate in laboratory and industry. With conventional separation method, the dehydration of pyridine aqueous solution is difficult and requires strong drying chemicals. To overcome these difficulties, several researchers have investigated on the separation of pyridine from aqueous solution through polymer membranes. Kujawski reported several ion-exchang membranes containing carboxylic and sulfonic fuctional group for dehydration of aqueous pyridine solution [1]. We have applied the idea of activation of water tranport through ion-dipole interactions between polymer membrane and aclueous feed. Our previous studies reported on the in-situ complex membrane to separate water from aqueous pyridine solution based on simple acid'-base theory [2, 3]. Water transport was enhanced through in-situ complex formation between the , acid moiety in the membrane and the incoming pyridine moiety in the feed.

  • PPG and BPA-type polyurethane prepolymers(NCO terminated) were obtained from bisphenol A and four types of PPG, having different molecular weight and numbers of functional groups. PPG and BPA-type polyurethane dimethacrylates were synthesized by reacting PPG and BPA-type polurethane prepolymer with 2-HEMA respectively. PPG-type polyurethane dimethacrylates were formulated with initiator(CHP), inhibitor(hydroquinone) and reactive diluent(TEGDMA). The effect of formulation on the torque changes was studied. Four kinds of PPG-type polyurethane dimethacrylates, having different molecular weight and numbers of functional group, were formulated with the same amount of CHP, TEGDMA and hydroquinone. The effects of the molecular weight of PPG-type polyurethane dimethacrylate and functional group numbers of PPG-type polyurethane dimethacrylates on the torque were investigated. These results showed that the torque of PPG-type polyurethane dimethacrylates, having same numbers of functional group, increased with decreasing molecular weight of dimethacrylates and torque of PPG-type polyurethane dimethacrylate, having similar molecular weight, was increased with increasing the number of fuctional group. The glass-transition temperature(Tg) of gels obtained by thermosetting cure for the four kinds of PPG-type polyurethane dimethacrylates were measured by DSC and molecular weights between cross-links(Mc) were calculated from Tg changes.
