  • Dryfilm method by using 3M Petrifilm$^{TM}$ has been examined to replace conventional agar method for isolation of microorganisms from foods. The objectives of the present study were to evaluate suitability of dryfilm method as a microbial isolation method and to determine the effect of antimicrobial agent on dryfilm for isolation of microorganisms from foods. Five different foods, milk, ground beef, fishery surimi, Takju and wheat flour were used to isolate the natural microflora in foods and the inoculated Escheri chia coli. Standard method agar (SMA, Difco) and Petrifilm$^{TM}$ aerobic count (PAC, 3M) were used to isolate total microorganisms from foods. Violet red bile agar (VRBA), brilliant green lactose bile (BGLB) broth and Petrifilm$^{TM}$ coliform count (PCC, 3M) were used to isolate coliforms from foods. E. coli broth (EC broth) and Petrifilm$^{TM}$ E. coli count (PEC, 3M) were used to isolate E. coli from foods. Acidified potato dextrose agar (APDA) and Petrifilm$^{TM}$ yeast & mold count (PYMC, 3M) were used to isolate yeasts and molds from foods. Total aerobic plate counts isolated from five different foods by SMA and PAC (3M) were riot significantly different each other at P<0.05 level and were highly correlated each other ($\geq$0.96). Mugwort extract as an antimicrobial agent did not affect microbial enumeratiion of Dryfilm. Significantly higher number of coliform colonies were formed on VRBA than PCC (3M) from ground beef, but they were not significantly different in coliform colonies from milk samples. PCC (3M) and BGLB were not significantly different for enumeration of coliforms in milk and beef samples. Significantly higher number of E. coli were isolated by EC broth than PEC from ground beef, but these were not significontly different for enumeration of E. coli from milk. Yeast and mold counts isolated from Takju and wheat flour by APDA and PYMC (3M) were not significantly different at P<0.05 level. These data indicate that dryfilm method by using 3M Petrifilm$^{TM}$ can be successively used as an alternative to conventional agar method for enumeration of microorganisms in various foods.

  • The effects of pressure cooker brand awareness, in terms of rice cooking performance, were evaluated using consumer acceptability tests. A blind test was performed using rice samples cooked by 3 different pressure cookers without any brand information, and a brand awareness test followed with the same informed consumer panel. Overall acceptability, glossiness, stickiness, hardness, flavor, and color were evaluated and compared to determine whether or not there were changes on consumer choice for acceptability. Brand A and brand B were not significantly different in their overall acceptability, moisture content, flavor, or color (p > 0.05), but they were significantly different for glossiness, stickiness, and hardness. Brands A and C were significantly different for all the attributes (p < 0.05). In the brand awareness test, brands A and B were not significantly different in their liking scores for all the attributes (p > 0.05). Brand C had significantly lower liking scores for overall acceptability, glossiness, stickiness, hardness, and moisture content than the other brands (p < 0.05). When comparing the liking scores for all the attributes with those of the blind test, the scores of the brand awareness test were slightly higher. For brand A, there were changes in its liking scores for overall acceptability, flavor, and glossiness (p < 0.05). However, brands B and C had brand awareness effects for all the attributes (p < 0.05).

  • Purpose: This examined the effect of Kinesio taping pre-intervention on the pain, tenderness, proprioceptive sensation, and muscle strength associated with delayed onset muscle soreness. Methods: Thirty subjects were divided into a Kinesio taping application group of 15 subjects and a control non-taped group of 15 subjects, and the changes in individual variables were analyzed before taping and at 24, 48, and 72 hours after taping using two-way repeated ANOVA. Post-hoc t-tests were conducted in the cases with intergroup interactions, and the significance level ${\alpha}$ was set to ${\alpha}=0.01$. Results: The changes in pain during rest were significantly different only for the times, while the changes in pain during exercise were significantly different for the times, interactions between the times and groups, and intergroup changes (p<0.05). The changes in tenderness were significantly different for the times and for interactions between the times and groups (p<0.05). The changes in proprioceptive sensation were significantly different for the times, interactions between times and groups, and intergroup changes (p<0.05). The changes in muscle strength were significantly different only for the times (p<0.05). Conclusion: The application of Kinesio taping had positive effects on the pain, tenderness, and proprioceptive sensation of delayed onset muscle soreness. These results suggest that Kinesio taping can be a useful therapeutic factor in future studies and in clinical settings.

  • The present study was performed to investigate the effect of cereal fiber on lipid concentration of liver and serum in rats. Male Sprague-Dawley rats weighing 180$\pm$4g were divided into five groups by completely randomized block design : R, BR, B, W, and F. Each group fed a diet containing 0.7% cholesterol and a kind of cereal among rice(R), brown rice(BR), barley(B), whole wheat(W), and wheat flour(F) for 5 weeks. The results were summarized as follow : 1) Food intake. weight gain and feed efficiency ratio were not significantly different among the groups. 2) Fecal wet weight and dry weight were significantly higher in W group which fed the most amount of IDF(insoluble dietary fiber). 3) The weight of large intestine was significantly heavier in the W group compared to the others. But the weights of liver, stomach and small intestine were not significantly different among the groups. 4) Total lipid. triglyceride(TG) and total cholesterol(TC) content in liver were significantly different among the groups. The values were the lowest in the B group whose intake of SDF(soluble dietary fiber) was the highest 5) TC content in serum was not significantly different among the groups. TG content in serum was significantly lower in the rest groups than in the R group. HDL-c and free-c content in serum were significantly higher in the B group than in the rest groups. HDL-c/LDL-c, free-c/ester-c ratio were the highest in the B group but not significant. Above results show that the dietary fiber contained in cereals has physiological effects and they are different depending on fractions, IDF and SDF.

  • The purposes of this study were to describe and compare pint moments according to 6 types of gait methods during free speed. 15 volunteers(7 male, 8 female: mean age = 23.33 yrs.) participated and performed 6 types of gait methods. From the 3 types of pint moments of lower extremities(hip, knee, ankle and foot), the following results were made: 1. In left hip pint, the flexion-extension moment was not significantly different, but the adduction-abduction moment and rotation moment were showed different curves during stance phase. 2. In left knee pint, the flexion-extension moment was not significantly different, but the varus-valgus moment and rotation moment were showed different curves during stance phase. 3. In left ankle and foot the dorsiflexion-plantarflexion moment was not significantly different but the varus-valgus moment and rotation moment were showed different curves during stance phase. In conclusion, because weight loading gait with 10-20% of body weight were normal gait patterns, It was inferred that all weight loading gaits did not indicate noxious reactions of human body.
