The purpose of this study was to find out the utilization status of Korean rice-cakes and the evaluation degrees of their commercial products by subjects. The subjects were 530 housewives lived in Seoul, Deajeon, Youngju city, and Secheon khun. We conducted this survey from November 16 to 28, 1987 by questionnaire method. The results obtained can be summarized as follows; 1. In the subjects' home, 37 kinds of Korean rice-cakes were used. All of them, Inchelmi (67.9%), Songpyeon (66.6%), Whinddeg (51.4%) and Gaepiddeg (43.4%) were frequently used. 2. All of ceremonial days, Korean rice-cakes were used most frequently on the wedding day but they were used scarecely on the funeral day. 3. On the birth day of children and adults, cakes were used more frequently than Korean rice-cakes. 4. All of Korean festival days, Korean rice-cakes were used most frequently on New Year's day. 5. In the future, most housewives (61.7%) hoped to make the Korean rice cakes of themselves at home. 6. Convenience (65.8%) was the most favored cause purchasing the commercial products but many housewives (44.3%) wanted to make the Korean rice-cakes of themselves at home. 7. All the quality properties of commercial products, taste and color property were favored and price, package, storage and hygienic property were poorly evaluated by housewives. 8. The evaluation about color property of commercial products were affected by resident place variable of housewives (P<0.05) and hygienic property were affected by resident place and academic career variable of housewives significantly (P<0.01). And package property of them was affected by dwelling house type significantly. (P<0.05) 9. Housewives indicated that commercial products were improved hygienic property (37.0%), price (23.8%), package (15.6%), taste (11.1%), storage (10.1%) and color (2.4%) in order.

As an exploratory research on China's animation, this study aims to enhance an understanding of the trends and characteristics of China's animation through examining its history and to forecast its future development trajectory. From its founding to recent period, China tried to maintain Communist political system through imbuing national identity to its people through management and supervision of media products under direct government's leadership in combination with ideological education. Such policy was also implemented in animation, major audience of which is children. With regard to the introduction of the policy and its influence, five historical phases could be identified as follows. During the first phase, from the founding of the Republic until the Cultural Revolution, national culture was introduced to China's animation. The second phase, which corresponds with the Cultural Revolution period, marks the decline of national culture. National culture was reemphasized during the third phase that follows the Cultural Revolution, which led to the nomination of the 'China school,' followed by the fourth phase, during which China's animation suffered the second decline due to the spread of TVs and foreign animation imports. Reintroduction of national culture on China's animation in the context of rapid industrialization process before and after 2000 characterizes the recent phase. It can be expected that although there could be some change in methods and forms, China's animation, which introduced national culture from its inception and maintained remarkable resilience following the period of decline, will continuously stress the its own national cultural identity.

This study was conducted to isolate lactobacilli having probiotic characteristics to be used as health adjuncts with fermented milk products. Acid tolerant strains were selected in Lactobacilli MRS broth adjusted to pH 4.0 from 80 healthy persons (infants, children and adults). And bile tolerant strains were examined in Lactobacilli MRS broth in which 1.0% bile salt was added. By estimation above characteristics, the strains No. 27, which was isolated from adult feces, was selected and identified as Lactobacillus salivarius subsp. salivarius based on carbohydrate fermentation and 16S rDNA sequencing. It was used as a probiotic strain in fermented milk products. The pH of fermented milk decreased from pH 6.7 to 5.0 and titratable acidity increased from 0.3% to 1.0% by L. salivarius subsp. salivarius (isolation strain 20, 35, and 37), when incubated for 36 h at $37^{\circ}C$. The number of viable cell counts of fermented milk was maximized at this incubation condition. The SDS-PAGE evidenced no significant change of casein but distinct changes of whey protein were observed by isolated L. salivarius subsp. salivarius for titratable acidity being incubated by $0.9{\sim}1.0%$ at $37^{\circ}C$. All of the strains produced 83.43 to 131.96 mM of lactic acid and 5.39 to 26.85 mM of isobutyric acid in fermented products. The in vitro culture experiment was performed to evaluate ability to reduce cholesterol levels and antimicrobial activity in the growth medium. The selected L. salivarius subsp. salivarius reduced $23{\sim}38%$ of cholesterol content in lactobacilli MRS broth during bacterial growth for 24 hours at $37^{\circ}C$. All of the isolated L. salivarius subsp. salivarius had an excellent antibacterial activity with $15{\sim}25$ mm of inhibition zone to E. coli KCTC1039, S. enteritidis KCCM3313, S. typhimurium M-15, and S. typhimurium KCCM40253 when its pH had not been adjusted. Also, all of the isolated L. salivarius subsp. salivarius had partial inhibition zone to E. coli KCTC1039, E. coli KCTC0115 and S. enteritidis KCCM3313 when it had been adjusted to pH 5.7. The selected strains were determined to have resistances of twelve antibiotic. Strains 27 and 35 among the L. salivarius subsp. salivarius showed the highest resistance to the antibiotics. Purified ${\alpha}$-galactosidase was obtained by DEAE-Sephadex A-50 ion exchange chromatography, Mono-Q ion exchange chromatography and HPLC column chromatography from L. salivarius subsp. salivarius 27. The specific activity of the purified enzyme was 8,994 units/mg protein, representing an 17.09 folds purification of the original cell crude extract. The molecular weight of enzyme was identified about 53,000 dalton by 12% SDS-PAGE. Optimal temperature and pH for activity of this enzyme were $40^{\circ}C$ and 7.0 respectively. The enzyme was found to be stable between 25 and $50^{\circ}C$. ${\alpha}$-galactosidase activity was lost rapidly below pH 5.0 and above pH 9.0. This enzyme was liberated galactose from melibiose, raffinose, and stachyose, and also the hydrolysis rate of substrate was compound by HPLC. These results indicated that some of the L. salivarius subsp. salivarius (strain 27 and 35) are considered as effective probiotic strains with a potential for industrial applications, but the further study is needed to establish their use as probiotics in vivo.

This study was conducted to investigate the efficacy of using a coating of gelatin extracted from refiner discharge to extend the shelf life of salmon during cold storage ($5^{\circ}C$). Relative percentage of moisture loss in gelatin-coated salmon during cold storage was less than that of uncoated salmon. The treatment of salmon with gelatin reduced volatile basic nitrogen (VBN) formation throughout the entire storage period. Measurements of the peroxide value (POV), fatty acid composition, and (20:5n-3+22:6n-3)/16:0 ratio during cold storage indicated that the coating of salmon with gelatin from refiner discharge effectively suppressed lipid oxidation over the entire storage period. The extent of sensory color change during cold storage was less in the gelatin-coated than in the uncoated salmon. From the results of chemical measurements, such as relative moisture content, VBN, POV, fatty acid composition, (20:5n-3+22:6n-3)/16:0 ratio, and sensory color change, the conclusion was made that the coating treatment of salmon with refiner discharge gelatin effectively suppressed moisture loss, lipid oxidation, and color deterioration over the entire storage period.

Numerous chemical agents have been developed to reduce the activity of cariogenic bacteria. Of these, chlorhexidine is acknowledged as the most effective. Gel and mouthrinse have been the traditional method of its application in the mouth. It has been reported that chlorhexidine varnish has prolonged inhibitory effect on the number of streptococcus mutans in saliva and plaque. Recently, chlorhexidine varnish and polyurethane sealant have been developed to promote prolonged anticariogenic effect of chlorhexidine. Products containing 10% chlorhexidine varnish and polyurethane sealant have been developed to prevent caries by reducing the number of streptococcus mutans in the oral cavity. The purpose of this study is to investigate the inhibitory effect of chlorhexidine varnish and polyurethane sealant on streptococcus mutans in the primary dentition. Children with primary dentition containing no active carious lesion were divided into two groups. To the experimental group (n=11), chlorhexidine varnish and polyurethane sealant ($Chlorzoin^{(R)}$, Knowell Therapeutic Technologies, Inc. Canada.) was applied once a week for four weeks according to the manufacturer's instruction. Only oral prophylaxis was performed on the control group(n=7). Caries activity was measured after using $Cariescreen^{(R)}$SM (Knowell Therapeutic Technologies, Inc. Canada,) to incubate streptococcus mutans before and 5, 12, 24 weeks after initial varnish application. The following results were observed.; 1. There was statistically significant decrease in the number of streptococcus mutans in the experimental group for 5 weeks(P<0.01), 12 weeks(P<0.05) after the initial application. but, by 24 weeks significant difference had disappeared. 2. As the inhibitory effect of chlorhexidine varnish and polyurethane sealant application is not everlasting, reapplication at 12-24 weeks should be needed.
