The whole cells of Actinoplanes missouriensis KCTC 1780 which produce glucose isomerase was immobillized by flocculation method for the effective production of high fructose syrup using packed-bed bioreactor system. Among the flocculation methods used In this study, the glucose Isomerase activity of flocculated cells using 5% polyethylenimmine and 0.2% glutaraldehyde was the highest as 46.3 unit, and the flocculant was 10.3g(wet weight) per 100m1 of broth, and the residual activity was 92.5%. In the batch operation of glucose isomerization using the flocculated cells, the optimum pH, temperature and isomerization ratio were 7.0, 75$^{\circ}C$ and 31%, respectively. The optimum concentration of Mg2+ which was activator on the glucose isomerization of flocculated cells was 0.1M, and glucose isomerase activity was increased by about 40% compared to none of Mg2+. In the packed-bed bioreactor system with 1.2 hour of residence time at 7$0^{\circ}C$, the reaction stability maintained until 96 hour without toss of activity, and the equilibrium was kept up to 120 hours of the operation.

The purpose of this study was to establish the most favorable processing method for soybean Dasik. Factors were kind of sugar (honey, syrup, oligo sugar), amount of sugar (50 g, 60 g, 70 g) and number of kneading (20 times, 30 times, 40 times). Physical characteristics were measured by moisture content, color difference and texture. Moisture content was increased in order of honey, oligo sugar and syrup. Lightness of soybean Dasik was different with amount of sugar. The tendency of L value and b value were dominent by honey. Lightness, redness and yellowness had no difference with the kind of sugar and number of kneading. Hardness was not a significant factor. Springiness was significantly different by the kind and amount of sugar. Cohesiveness, gumminess and chewiness was influenced by the kind and amount of sugar, the interaction of kind and amount of sugar.

This study examined low calorie sweeteners (fractooligosaccharide, xylitol, erythritol, agave syrup, stevioside) instead of sugar for $Teriyaki$ sauce to satisfy customers' health needs. After adding sugar, stevioside, agave syrup, erythritol, xylitol, and fractooligosaccharide to $Teriyaki$ sauce, we measured moisture and viscosity. According to the results, the sauce with stevioside had a low moisture content, but its value was the highest in viscosity. The sauce with xylitol had average sweetness equal to that of sugar, but its salinity was very low. There was no significant difference in pH value. The difference in sweet taste showed that the sauce with xylitol met the requirement of sweet taste, soy sauce flavor, taste and savory taste. Therefore, xylitol was a good ingredient for $Teriyaki$ sauce.

To research were procedure condition of cellulase and remove effect of endocarp of mandarine orange from the result obtained it could be summarize as follow. 1. Optimal conditions affecting the production of cellulolytic enzyme of Aspergillus saitoi are followings: optimal temperature $30^{\circ}C$ and optimal culture period 3days. 2. When mandarine orange was soaked in 10 fold diluent of enzyme(diluent of enzyme: mandarine orange=2 : 1) and reacted under $40^{\circ}C$ for 3.5-4hrs, it was most effective and available to the remove of endocarp, flavour, and lustre important to the canning process of mandarine orange syrup.

The effects of dipping syrups prepared with isomaltooligosaccharides on the characteristics of Yackwa were investigated. The dipping syrups were prepared replacing sucrose with 0, 25 and 50% isomaltooligosaccharide. Physical and sensory characteristics of Yackwa were evaluated. Isomaltooligosaccharides increased dehydration rate and increased absorption rate of dipping syrups. Yackwas dipping in the syrup containing isomaltooligosaccharides were more acceptable than those with sucrose syrup. The acceptability was significantly correlated with shinness(p<.01), moistness(p<.05), adhesiveness(p<.05), cohesiveness(p<.01), roasted taste(p<.0l) and sweetness(p<.05). Therefore, isomaltooligosaccharides might be a good alternative for sucrose in making dipping syrup of Yackwa.

Maple syrup urine disease (MSUD) is a disorder that involves the metabolism of branched chain amino acids, arising from a defect in branched-chain ${\alpha}$-keto acid dehydrogenase complex. Mutations have been identified in the BCKDHA, BCKDHB, or DBT genes, which encode different subunits of the BCKDH complex. Although encephalopathy and progressive neurodegeneration are its major manifestations, the severity of the disease may range from the severe classic type to milder intermediate variants. We report two Korean siblings with the milder intermediate MSUD who were diagnosed with MSUD by a combination of newborn screening tests using tandem mass spectrometry and family genetic screening for MSUD. At diagnosis, the patients' plasma levels were elevated for leucine, isoleucine, valine, and alloisoleucine, and branched-chain ${\alpha}$-keto acids and branched-chain ${\alpha}$-hydroxy acids were detected in their urine. BCKDHA, BCKDHB, and DBT analysis was performed, and two novel mutations were identified in BCKDHB. Our patients were thought to have the milder intermediate variant of MSUD, rather than the classic form. Although MSUD is a typical metabolic disease with poor prognosis, better outcomes can be expected if early diagnosis and prompt management are provided, particularly for milder forms of the disease.

In the first of two experiments, chemical composition (Ash, CP and CF contents), nutritive value (in vitro organic matter disappearance "lVOMD" and energy content "ME") and nitrogen retention of chopped date fronds (CDF) as affected by chemical treatment (CT) and storage duration (SD) were investigated. The experimental design was a completely randomized block, arranged in a $3{\times}4$ factorial, with 3 (CT) and 4 (SD) as the main factors using 2 replications / treatment. Three chemical treatments, were used : Control (With zero or no chemical treatment); treatment with 4% urea solution (w /w) and treatment with 4% urea + Date syrup extract (DS). The 4 (SD) were: Control (immediately after opening - without any storage or zero time storage); one month storage period; two months storage period and three months storage period. Both (CT) and (SD) had significant effects (p < 0.05) on CP and ash contents of the CDF, however there were no significant effects (p > 0.05) due to (CT) and (SD) on CF and nutritive value. High retention value (> 80%) for nitrogen was reported for the treated CDF, immediately after opening the incubated material (zero SD). However, nitrogen retention decreased with increasing (SD) to 67% after one month (SD) but tended to stay at a fairly constant level of 67% until 3 months of storage. In experiment 2, the feeding value of treated CDF was evaluated in comparison to Rhodes grass hay, using growing goats and sheep. A $4{\times}2$ factorial design was used (Four roughage sources were used : Rhodes grass hay, untreated CDF, urea-treated CDF and CDF treated with urea + DS with sheep and goats as two animal species, using three animals / treatment). Untreated CDF had a similar feeding value to Rhodes grass hay. However treatment of CDF with urea alone or with urea + DS depressed animal performance of both goats and sheep, apparently due to depression of feed intake (appetite). Feeding untreated CDF decreased feeding cost by 29% and cost/kg gain by 23%. CDF showed a good potential as a cheap local roughage and emergency feed for ruminants in the Sultanate.

To prepare acrylic pressure sensitive adhesives (PSAs), quaternary copolymer syrups were photopolymerized from 2-ethylhexyl acrylate and 2-hydroxyethyl acrylate as default constituents and isobornyl acrylate and tetrahydrofurfuryl acrylate (THFA) as variable constituents. After polymerization, 1,6-hexanediol diacrylate and photoinitiator were added and then crosslinked by UV-irradiation to prepare the PSAs. The characteristics of the syrup such as viscosity, molecular weight, and solid content were investigated. As increasing THFA contents, the relationship between molecular weight and solid content of the syrup was reciprocal. Also, the relationship between peel strength and surface energy of the PSAs showed the same tendency. All the PSA samples showed high transmittance (more than 92%), low haze (less than 1.0%) and low color-difference (less than 1.0).
