This study was designed to investigate the effect of exercise prescription service on user satisfaction and reuse intention of fitness center users in C region, Gangwon-do. The subjects of this study were 250 fitness center users aged 20 and over. Survey was conducted to examine users satisfaction and reuse intention. The final analysis data is 227 copies and the results are as follows. First, there was a significant difference in sex at the facility of satisfaction of use(t=2.308, p=.022). The marriage showed a significant difference in the price among user satisfaction(t=2.490, p=.014) and reuse intention(t=-1.968, p=.05). Age showed significant differences in the duration of participation(F=7.117, p=.000), frequency (F=6.171, p=.000), and intensity(F=2.791, p=.027). User satisfaction showed significant differences according to price(F=6.171, p=.000), leader(F=3.083, p=.017) and reuse intention(F=2.699, p=.032). There was a significant difference in education groups in terms of duration of participation(F=3.656, p=.007) and frequency(F=3.164, p=.015). leader(F=5.170, p=.001) and price(F=2.899, p=.023) were different in user satisfaction. Jobs showed a significant difference in the duration of participation(F=4.685, p=.000), intensity(F=2.373, p=.023) and reuse intention(F=4.840, p=.000). Monthly income showed a significant difference in user satisfaction(F=4.651, p=.001) and facility(F=2.606, p=.037). Second, there was a significant difference in the duration of participation according to presence or absence of exercise prescription service(t=-4.410, p=.000). There was also significant differences in the user satisfaction(t=-7.951, p=.000), leader(t=5.304, p=.000), facility(t=2.033, p=.043) and reuse intention(t=4.640, p=.000) in terms of the presence of exercise prescription service. Third, in the relation between exercise prescription service and the participation level, there was a significant effect of the leader(β=.221, p=.001) and the price(β=.135, p=.045) of user satisfaction, and the reuse intention(β=.182, p=.007). Fourth, among the user satisfaction influenced by exercise prescription service, facilities(β=.178, p=.005) and leader(β=.497, p=.000) were found to affect reuse intention.

In P300-based concealed information test (P300 CIT), it evaluates whether the P300 amplitude for the probe is significantly greater than that of the irrelevant to determine if the suspect is telling a lie. An independent sample t-test or a bootstrap method can be used as a statistical test to make that decision. Rosenfeld et al. (2004) used the bootstrap method, claiming that "t tests on single sweeps are too insensitive to use to compare mean probe and irrelevant P300s within individuals" and their method has been accepted to date. The purpose of the study is to evaluate whether the power of t-test is lower than that of the bootstrap method in the P300 CIT. The Monte Carlo study was conducted by using EEG collected from 39 participants. The results showed that the type I error rates of the t-test and the percentile bootstrap method were similar and the power of the percentile bootstrap method was slightly higher than that of the t-test. The type I error rates of the t-test and the percentile bootstrap method were slightly lower than the significance level and the powers of the two tests were also slightly lower than that of the theoretical t-test. On the other hand, the type I error rate and power of the standard error Bootstrap method were the same as those of the theoretical t-test and its power was .012 ~ .081 higher than that of t-test depending on experimental conditions.

This experiment was conducted to investigate the effects of dietary pigment sources on the performance, color and antioxidant properties in broiler chick. Experimental diet was formulated to have isocalories and isonitrogen during the experiment period. Total xanthophylls content in the experimental diet was formulated to have 30ppm. Experimental trials were done for five weeks with six treatment groups; T1 (Control), T2 (Olo Glo, natural yellow pigment), T3 (Kern Glo, natural red pigment), T4 (canthaxanthin, synthetic red pigment), T5 (asthaxanthine, natural red pigment), and T6 (seaweed by-products). Body weight gain and feed intake were significantly lower (p＜0.05) in T6 group than in other treatments. Mortality was lower in T2, T3 and T4 than in control, but higher (p＜0.05) in T5 and T6. The sources of pigments did not have any effects on the dressed carcass and abdominal fat pad (p＞0.05). The gizzard weight was significantly lower in T6 (p＜0.05) than in others. Pigmentation of leg skin was significantly lower (p＜0.05) in control and T6. Effects of dietary pigments was greater with red pigments than with yellow pigments, and those were also greater with natural pigments than with synthetic ones. The peroxide value (POV), thiobarbituric acid reactive substances (TBARS) and pH values of chicken meat were increased (p＜0.05) in all treatments at 12 day storage, and was higher (p＜0.05) in pigments supplementation group. No differences of CIE L$\^$*/(lightness) and b$\^$*/(yellowness) were not found by storage days and xanthophylls sources. The a$\^$*/(redness) after 12 day storage was significantly (p＜0.05) decreased in all treatments, but those of T4 and T5 were higher than those of others. These results showed that feeding of xanthophylls sources to chick could improve color intensity and inhibit lipid oxidation of leg meat.

This study was carried out to investigate the effects of inuloprebiotics (INPs), an alternative antibacterial growth promotor, from Jerusalem artichoke extract (Helianthus tuberosus L.) on egg production and quality in Hyline brown laying hens. The hens were divided randomly into four treatment groups and housed in individual cages for 10 weeks: a control group (0 ppm INP) (T1), 450 ppm (T2), 600 ppm (T3), and 750 ppm (T4). Egg production, egg weight, Haugh unit, eggshell thickness, and breaking strength were significantly higher in all of the INP-treated groups compared with the control (p<0.05). Egg cholesterol was highest in the T1 group and decreased with INP addition from 15.04 to 17.98% (p<0.05). Compared with the T1 group, triglycerides in the blood and in total cholesterol decreased significantly in groups T2, T3, and T4 by 21.71-24.07% and 27.17-30.36%, respectively (p<0.05). The growth of cecum Bifidobacterium and Lactobacillus was stimulated in groups T2, T3, and T4 compared with T1, whereas the growth of Escherichia and Salmonella was clearly inhibited (p<0.05). The results suggest that the addition of 450 ppm INP to the diet of laying hens can improve egg production and egg quality.

This study was carried out to investigate the effect of safflower seed on the physicochemical properties of ground pork during frozen storage. Three types of ground pork were evaluated: 20% pork back fat added (T0, control), 10% pork back fat and 10% added safflower seed (T1), and 20% added safflower seed (T2). Water holding capacity decreased with longer storage period, and that of T2 was the highest (p<0.05). Cooking loss increased with longer storage period, and that of T1 and T2 was higher than that of T0 (p<0.05). The reduction in diameter of T0 increased, but that of T1 and T2 was not significantly different with longer storage period. Hardness and chewiness increased, but springiness decreased with longer storage period (p<0.05). Hardness, springiness and chewiness of T2 was the highest (p<0.05). The pH decreased with longer storage period (p<0.05), and those of T0, T1 and T2 were pH 5.41, 5.43 and 5.32, respectively, after 50 days of storage. The TBARS (2-thiobarbituric acid reactive substances) values of T0 and T1 increased, but that of T2 was not significantly different with longer storage period. The TBARS values of T0, T1 and T2 were 4.76, 2.77 and 0.54 mg malonaldehyde/kg, respectively, after 50 days of storage. The $L^*$, $a^*$ and $b^*$ value of T0 was the highest among the samples (p<0.05), the $a^*$ value of the samples decreased with longer storage period (p<0.05). In conclusion, this study demonstrates that the addition safflower seed tended to improve physiological properties and antioxidative effects.

This study was conducted to investigate the effect of duck and pork meat mixing ratio on quality characteristics of emulsion type sausage at $4^{\circ}C$ during 5 weeks. Treatments on the basis of the meat content were subjected to 100% duck meat (T1), 100% pork meat (T2), 50% duck meat + 50% pork meat (T3), 40% duck meat + 60% pork meat (T4), and 30% duck meat + 70% pork meat (T5). The moisture content was significantly (p<0.05) higher in TI sample but significantly (p<0.05) lower in T2 sample than those in comparison to the other treatments. Crude protein and fat content were significantly (p<0.05) higher in T2 sample compared to the other treatments. CIE $L^*$value was significantly (p<0.05) lower in T1 sample than those of other treatments until 5 weeks of cold storage. CIE $a^*$value was significantly (p<0.05) higher in T1 sample but significantly (p<0.05) lower in T2 sample than those in comparison to the other treatments until 5 weeks of cold storage. Hardness was significantly (p<0.05) higher in T4 sample compared to the other treatments during all cold storage. Cohesiveness was significantly (p<0.05) higher in T5 sample compared to the other treatments until 2 weeks of cold storage. The results of sensory evaluation showed that the meat flavor, taste and texture were significantly (p<0.05) lower in T5 sample compared to the other treatments whereas no difference among treatments except T5 sample. Overall acceptability was significantly (p<0.05) lower in T5 sample compared to the other treatments. Therefore, these results suggested that the ratio of 40% duck meat and 60% pork meat is appropriate levels for hardness and palatability when manufacturing emulsion type sausage with duck meat.

Kidney bean was used in the brewing of Takju. The Takju formed varied the percentage of kidney bean used; that is, 0%(only rice) in $T_{-1}$, 100%(only kidney bean) in $T_{-2}$, 90% in $T_{-3}$, 80% in $T_{-4}$, 70% in $T_{-5}$, 60% in $T_{-6}$, and 50% in $T_{-7}$. We determined the total sugar, pH, reducing sugar, alcohol production, acidity, and DPPH free radical scavenging activity of Takju. The acidic value of $T_{-1}$ was above that of $T_{-6}$, and the pH of $T_{-2}$ was above that of $T_{-1}$. Both satisfy the food code parameters (namely, below 0.5 in acidity, 3.8~4.7 in pH). The alcohol production of $T_{-1}$ was above that of $T_{-2}$. For 2 days of fermentation, the reducing sugar of $T_{-1}$ totaled 2, down from 4.96%. After fermentation, there was not much difference from 4 to 12 days. The antioxidative effect of $T_{-1}$ proved to be much better than those of the other. Thus, we can be seen that these results thus indicate that the role of kidney bean added to Takju show good antioxidative activity. From the result of sensory test, we also concluded that the taste of Takju kidney bean is very similar to that of Takju with rice.
