Purpose: This study aims to examine the effect of increased physical activity (PA) regarding health-related quality of life (QOL) and nutrition intake in hemodialysis patients. Methods: The research was quasi-experimental using pre-test and posttest design. The participants were 60 patients, 30 each in the experimental and control group. The program was up to eight weeks long and involved two kinds of aerobic exercises: intradialytic aerobic exercise to be performed thrice a week and walking for up to seven days a week. The 60 patients undergoing hemodialysis for end-stage renal disease underwent assessment of International Physical Activity Questionnaires (IPAQ), 24-hour diet recall and a 12-item short-form health survey (SF-12; physical component summary score(PCS) and mental component summary score(MCS)) before and after the exercise program. Nutrition intake was assessed using CAN-2.0. Data were analyzed using descriptive statistics, independent t-test, 𝑥2 test, and Mann-Whitney U test. Results: In the experimental group, PA post-test scores were also significantly higher than the pre-test scores and the levels of physical component summary score (PCS) in QOL were significantly improved post-test, but the scores on nutrient intake did not improve. The levels of PCS were significant correlations animal protein, manganese, selenium, and Vitamin C. Although there was no group effect, total calorie of nutrition intake was higher than the comparison group. Conclusion: Combined intradialytic exercise and walking was found to be effective on PA, and PCS in QOL. Therefore, the findings of the current study may provide an appropriate guidance for encouraging exercise by hemodialysis patient.

Twenty four Hanwoo cull cows were assigned to 2 groups, control and melengerol acetate(MGA)+selenium supplement containing vitamin E(SeE), based on the parity(6.5±1.7 birth) and body weight (493.17±55.61kg), and the experiment was conducted to establish the reasonable fattening method of cull cows for 240 days. Average daily body gains during 240 days were 0.51kg and 0.63kg in control and MGA+SeE, respectively(P<0.10). DDMI/ADG of MGA+SeE group improved compared to control group(P<0.05). Therefore, supplementation of MGA+SeE in concentrates may accelerate both of the growth rate and feed efficiency in Hanwoo cull cows. MQI from MGA+SeE was more developed based on the larger rib-eye area and thinner backfat thickness in carcass than that from control. Marbling score for MGA+SeE tended to increase compared to control. Dietary Se supplementation significantly affected muscle Se concentration in longissimus dorsi meat of MGA+SeE group(P<0.05). Similar results to Se were obtained from α-Tocoperol concentration. During 7 days of simulated retail display, accumulations of thiobarbituric acid reactive substances(TBARS) concentration in beef was greater(P<0.05) in control than in supplemented cows. These results supported the hypothesis that supplementation of MGA+SeE improve the growth performance and carcass grade both by the growth stimulating effect of MGA+SeE and by preventing the oxidation of the longissimus dorsi muscle in Hanwoo cull cows.

The effects of turmeric and fermented turmeric by Bacillus natto on antioxidant activities, liver function recovery of acute hepatotoxicity mice, and serum lipid parameters in high fat diet fed mice were investigated. In the results of antioxidant activity by DPPH method, fermented turmeric had higher antioxidative activity than turmeric. Acute hepatotoxicity was induced by 0.5 mL of carbon tetrachloride ($CCl_4$) per kg of mice. Unlike turmeric, fermented turmeric significantly reduced the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) after 5 days compared to the controls with 0.5% methyl cellulose (p<0.05). In addition, higher recovery of liver damage by $CCl_4$ was observed in mice with fermented turmeric than with turmeric. High fat (20%) diet fed mice were divided into 4 groups to investigate the effects of turmeric and fermented turmeric on serum lipid parameters: C (vehicle), TuL (low dose (80 mg/kg) with turmeric), TuH (high dose (160 mg/kg) with turmeric), FTuL (low dose with fermented turmeric), and FTuH (high dose with fermented turmeric). The levels of LDL-cholesterol and HDL-cholesterol were significantly reduced and increased in FTuL, FTuH and TuH groups compared to the C group, respectively. However, there was no significant change in triglyceride levels by either turmeric or fermented turmeric compared to those by control. Collectively, these results strongly suggest that fermented turmeric by Bacillus natto could be used as a functional food for enhancement of health with better consumer acceptance.

The object of this study is to investigate the quality change of sweet basil grown with selenium(Se) in hydroponic culture. Sweet basil was cultured with 1 fold herb nutrient solution as suggested by European vegetable R & D Center in Belgium. Before three weeks harvest, sodium selenate(N $a_2$Se $O_4$) was supplied to 2 and 4 mg. $L^{-1}$ in the nutrient solution. Sweet basil was stored at 1$0^{\circ}C$ using 40um ceramic film and PET (polyethylene terephalate) for 15 days in modified atmosphere(MA) storage condition. The weight loss of sweet basil was higher in non-treatment compared to Se treatments in both of two films but it was decreased over 5% in PET treatment. Se concentrations in leaf tissues increased in the response to the treated levels of N $a_2$Se $O_4$concentrations, and this tendency was appeared similar results after storage. There was no significant effect of packing materials on volatilization of Se in sweet basil. The total chlorophyll and essential oil content was increased with increasing N $a_2$Se $O_4$concentration in nutrient solution. The amount of volatilization flavor was not higher at N $a_2$Se $O_4$4mg. $L^{-1}$ treatment compare to others during storage. Se content was 112.73 ug. $g^{-1}$ dry mass at 2 mg. $L^{-1}$ treatment before storage and the decrease of Se content was observed by 50% at 15 days after storage. The condition, which N $a_2$Se $O_4$2mg. $L^{-1}$$^{plement}$ in nutrient solution during growth stage and stored with 40um ceramic film on 1$0^{\circ}C$are acceptable for maintaining of sweet basil quality. Moreover it can be a proper Se concentration for human health. Overall, Se treatment in nutrient solution has effect on promoting and maintaining quality of herb during storage life. Also, there was not significant change of essential oil compounds by volatilization of Se.mpounds by volatilization of Se.

Two experiments were conducted to investigate the effect of dietary selenium sources on performance and selenium retention in broiler chickens and laying hens. In experiment 1, the effects of dietary selenium sources and levels on the weight gain, feed intake, feed conversion, and selenium retention of meat in broiler chickens were investigated. for each growth phase, the basal diet was supplemented with 0 (control), 0.12 and 0.24 ppm Se from sodium selenite (SS) and 0.12, 0.24 and 0.60 ppm Se from selenium yeast(SY). Weight gain was significantly increased(P<0.05) in supplemental 0.24 and 0.60 ppm SY compared to the 0.24 ppm SS by diet during day 1 to 35, but feed intake and feed conversion were not affected by the source or the level of Se. Selenium concentrations of breast and leg muscle were significantly increased(P<0.05) in supplemental SS and SY compared to the control, and linearly increased(P<0.05) as dietary. Se level increased by SY, but there was no difference in supplemental 0.12 ppm SS compared to 0.24 ppm SS. In experiment 2, 12-week-experiment using Hy-Line laying hens(31 wk of age) was conducted to compare the effects of selenium sources and levels on egg production, egg weight, daily egg mass, feed intake, feed conversion, egg quality, and selenium retention of egg in laying hens. A corn-soybean meal basal diet was supplemented with 0 (control), 0.06 and 0.12 ppm Se from sodium selenite (SS) and 0.06, 0.12 and 0.30 ppm Se from selenium yeast(SY). Feed conversion was significantly improved(P<0.05) in supplemental 0.06 ppm SS compared to the control, but egg production, egg weight, daily egg mass, and feed intake were not affected by source and level of Se. Haugh unit was not affected by source or level of Se. Yolk color was significantly(P<0.05) higher in supplemental 0.3 ppm SY compared to the control and other supplement in week 12. Eggshell breaking strength was significantly(P<0.05) higher in supplemental 0.06 ppm SY(P<0.05). Thickness of eggshell was not affected by source or level of Se. Se concentrations of egg was significantly improved(P<0.05) in supplemental SS and SY compared to the control, and was significantly increased(P<0.05) as dietary Se level increased by SS and SY, especially SY more effective compared to the SS.
