To optimally convert corn hull, a byproduct from corn processing, into bioethanol using Pachysolen tannophlius, we investigated the optimal conditions for hydrolysis and removal of toxic substances in the hydrolysate via activated carbon treatment as well as the effects of this detoxification process on the kinetic parameters of bioethanol production. Maximum monosaccharide concentrations were obtained in hydrolysates in which 20 g of corn hull was hydrolyzed in 4% (v/v) $H_2SO_4$. Activated carbon treatment removed 92.3% of phenolic compounds from the hydrolysate. When untreated hydrolysate was used, the monosaccharides were not completely consumed, even at 480 h of culture. When activated carbon.treated hydrolysate was used, the monosaccharides were mostly consumed at 192 h of culture. In particular, when activated carbon-treated hydrolysate was used, bioethanol productivity (P) and specific bioethanol production rate ($Q_p$) were 2.4 times and 3.4 times greater, respectively, compared to untreated hydrolysate. This was due to sustained bioethanol production during the period of xylose/arabinose utilization, which occurred only when activated carbon-treated hydrolysate was used.

The effect of sodium hexametaphosphate(SHMP) on the extraction of defatted sesame meal protein and the color and amino acid composition of protein concentrate have been studied. The highest amount of protein could be extracted with 1.5% SHMP and the extraction was effective at pH 12.0. The extraction rate tended to increase with increasing the flour to solvent ratio and about 60% of protein was obtained when adjusted the ratio to 1 : 40. Color of sesame protein concentrate was slightly improved by SHMP treatment. Lysine and methionine content were decreased in SHMP-treated protein concentrate but valine and leucine content were increased.

Sesame protein concentrate(SPC) was prepared from defatted sesame flour(DSF) at several different pH(2.0, 7.0, 9.0, 11.0) for protein extraction. Some of their functional properties were determined in order to compare the effects of pH during preparation of concentrates. Compared with DSF, nitrogen solubility was markedly improved in all SPC, and SPC extracted at pH 11.0 showed the highest solubility at all pH leaves examined. Fatabsorption was increased in all SPC prepared, but water absorption was decreased as the extraction pH of protein increased. The emulsifying properteis and foaming properties of SPC were remarkably higher than DSF. As the extraction pH of protein was increased, the emulsion activity was also increased, but emulsion stability was decreased. SPC extracted at pH 7.0 showed the highest foaming capacity on the other hand, the highest foaming stability was shown in SPC extracted at pH 2.0. As the protein extraction pH increased, the viscosity of the protein solution was increased. SPC extracted at pH 11.0 showed highest viscosity at all protein concentrations tested.

The purpose of the current study was to determine the effects of the introduction of polysaccharide chains onto the molecular surface of buckwheat proteins on buckwheat protein surface functionality. The whole buckwheat protein fraction (WBP) was prepared using 50 mM phosphate buffer (pH 7.5) containing 0.5 M NaCl and covalently linked with 6 kDa, 17.5 kDa, 40 kDa, 70 kDa, or 200 kDa dextran by Maillard-type glycation through controlled dry-heating at $60^{\circ}C$ and 79% relative humidity for two weeks. Conjugation with 40 kDa dextran improved the water solubility and emulsifying properties of WBP without causing a serious loss of available lysine; 84.9% of the free amino groups were conserved. In addition, we found that the introduction of dextran chains onto the molecular surfaces of WBP attenuated the antigenicity of WBP.

This study was conducted to investigate the effects of weight control program on nutrient intakes and physical fitness of Korean obese adult women. The subjects of this study were 33 obese adult women aged 30-65 years residing in Seoul. The weight control program for obese women included nutrition education, cognitive behavioral therapy and exercise for 12 weeks. There were significant decrease (p < 0.001) of blood pressure and atherogenic index of obese women after the weight control program. Energy intake was significantly decreased (p < 0.001) from 1556.9kcal to 1044.9kcal after 12 weeks of the weight control program. Also protein, fat and carbohydrate intakes were significantly decreased. The ratio of energy intakes per day for the subjects was carbohydrate 64% : protein 16% : fat 20%. The frequency of vegetables intakes was significantly increased (p < 0.05) and there were no significant differences in other food groups. After the weight control program, muscle endurance, flexibility, balance and explosive muscular strength of subject's physical fitness were significantly improved. These results suggest that the weight control program for obese women may contribute to nutrient intakes reduction and improvement of physical fitness.

It was discovered that ammonium phosphate in the medium played an important role in both growing mycelium and producing exopolysaccharides (EPS) from G. lucidum. In lower concentration levels of ammonium phosphate (0-3 g/l), an improved mycelial growth was observed by maintaining more filamentous morphology than in high concentrations (5-11 g/l). In addition, it was confirmed by comparing the factual dimension and frequency of the area regarding the mycelial pellets. This must be attributed to limitations of nutrient transfer by maintaining filamentous mycelium during the cultivation in a low ammonium phosphate containing medium. On the other hand, the best EPS production was observed in medium with the absence or low concentration of ammonium phosphate. The shear stress of the culture broth was greatly affected by the shear rate, as compared with that of the culture broth with high ammonium phosphate concentration. The rheological characteristics of the fermentation broth and filtrate worked well according to the Herschel-Bulkley model. It was also found that the morphological changes of the mycelium resulting from the ammonium phosphate concentration directly affected the rheological characteristics of the system and resulted in reversely affecting the EPS production levels. Based on these results, it can be concluded that delicate regulation of the ammonium phosphate concentration in the culture media should be provided in order to obtain optimal mycelial growth and/or EPS production.

This study was carried out to investigate the bactericidal efficacy of concentration (0.1, 0.2, and 0.4 ppm) and exposure time (10 and 30 min) of ozone on bacterial reduction rate of Salmonella typhimurium KCTC 2541 and Staphylococcus aureus ATCC 13515 in the distilled water (DW), and DW supplemented with 0.2% soluble starch (SS), and metal ion (MC) using argentums (Ag) and copper (Cu). The significant bactericidal differences of S. aureus were showed in the treatments of DW and SS, respectively, at the concentration of ozone above 0.1 ppm for 10 min, comparing the respective initial bacterial counts. The bacterial reduction of S. aureus was more sensitive than that of S. typhimurum at the same concentration of ozone. The bacterial reduction rate of SS treatment was slightly lower than that of DW treatment at the same concentration of ozone (p<0.05), however, the bacterial reduction rate of strains improved in the MC treatment compared to the DW treatment at the same concentration of ozone.

This study was performed to evaluate the effectiveness of a nutritional education program conducted by public health center in Jinju city for obese women. The subjects of this study consisted of 27 obese women(BMI $\geq$ 25) aged 35∼55 years in Jinju area, and the educational period was 6 weeks. We evaluated the anthropometric parameters and biochemical indices, dietary habits, dietary behaviors, nutritional attitude of obese women before and after the nutritional education. And also daily intake during the educational period were measured. Weight, obesity index, BMT, waist circumferences and hip circumferences of obese women were significantly decreased(p<0.001) after nutritional education, but changes of WHR, systolic blood pressure and diastolic blood pressure were not significant. There were no significant difference in total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, LDH and blood glucose level in serum before and after the nutritional education, but the indices tend to decrease after the nutritional education. There was significantly different change of dietary behaviors in 3 items among the dietary behavior after the nutritional education. Their dietary habit, dietary behavior and nutritional attitude scores were significantly improved after the nutritional education. Mean daily energy intakes was low compared with the RDA as 78.88%. The average carbohydrates, protein, fat ratio on the energy intakes was 63 : 17 : 20. The proportion of energy intake from snacks the was 12.91${\pm}$6.15%.

This study was conducted to examine the effect of HACCP implementation on the cost of medicine use, antibiotic utilization, and productivity of swine in Korea. Data were collected from forty-five swine farms before and after implementation of a HACCP system. The cost of medicine used, the number of different antibiotics used and the number of feeds containing antibiotic supplements added at the feed company tended to be lower (p>0.05) after HACCP implementation. Additionally, the number of feeds containing antibiotics supplemented at the farm was significantly lower after HACCP implementation (p<0.05). Moreover, the number of piglets born per sow per year and pigs marketed per sow per year were higher after HACCP implementation (22.0, 20.0) than before HACCP implementation (20.4, 18.9). These results suggest that implementation of HACCP systems on swine farms may provide beneficial effects such as reduction of medical expenses and improved productivity, as well as increased safety of livestock products for consumers.
