  • The study was attempted to observe effects of voluntary exercise on energy expenditure and on storage of excessive energy into body fat in adult mice. Mice, body weight 25-30g, were divided into two groups, exercise and sedentary group. Voluntary exercize by running wheel was allowed for former group but not for the mice of the latter group which were restricted by limiting space allowance 13.5$\times$11.5$\times$15.0cm per mouse. During a period of 4 weeks of feeding trial, they were fed ad libitum starch-casein based diet added with $^3\textrm{H}$-glucose (D-[1-$^3\textrm{H}$(N)]-glucose) at a level of 20 nCi per g of diet. Measurements were made to study hematology, lipase activity in epididymal adipose tissue, total contents of body waste and fat, and radiactivity of $^3\textrm{H}$-glucose incoporated into body fat. Dietary intake, body weight gain and amount of voluntary physical activities were also measured. The results obtained ard summarized as follows; 1) Amount of metabolizable energy intake, body weight gain and body fat were not statistically different between the two group. However, mice of the exercise group tended to show lower body weight gain body fat contants, but higher energy expenditure than those of the sedentary group. 2) Radioactivity of $^3\textrm{H}$-glucose incoporated into body fat appeared lower for exercise group expressd on a whole body fat basis. The activity was, however, higher for exercise group when expressed based on per g of fat compared to that of sedentary group. 3) Exercise group showed also higher activity of lipase in epididymal adipose tissue than the other group. 4) Mice whose physical activities were restricted appeared to have lower levels of hemoglobin and hematocrit values than of the exercise group. These results seem to support the theory that turn-over rate of body fat is activated by exercise and to suggest that consumed energy is to be converted primarily into body fat before its use as energy source by oxidation even during a period of continuous energy expenditure by exercise.

  • Objective: Joint mobilization for arthrokinematics altered by the positional fault of chronic ankle instability (CAI) is an effective intervention for stabilization. In this study, we compared the effects of ankle dorsi flexion range of motion (DFROM) and dynamic balance ability (DBA) in CAI patients via passive joint mobilization (PJM), a method traditionally performed in previous studies, and active joint mobilization (AJM), a method that can have a greater effect on cortical excitability with spontaneous movements. Design: Single-blind two-arm randomized controlled trial Methods: A total of 30 participants were registered: 15 each to the PJM and AJM groups. Each participant received a total of 10 intervention sessions, 10 minutes per session, 5 times a week for 2 weeks. PJM used Maitland's mobilization method to apply joint mobilization with talus in the posterior direction and AJM used an angular joint motion to induce patient's voluntary motion of medial malleolus anterior gliding and lateral malleolus posterior gliding, respectively. DFROM of the ankle was measured by using tape and DBA was evaluated by using the balance system. Results: Significant improvement was observed after intervention in both the PJM and AJM groups except for the DBA-anterior and DBA-right variables of the PJM group. There were statistically significant differences between the AJM and PJM groups in the DFROM, DBA-anterior, DBA-posterior, and DBA-right variables. Conclusions: The overall improvement of DFROM and DBA was found to be more effective in joint mobilization including voluntary movement. When it is accompanied by voluntary movement, it further affects the neuromuscular system of the ankle.

  • Purpose: The purpose of this study was to show the effects of voluntary change of weight bearing on the vastus medialis oblique and the vastus lateralis ratio during squat exercise. Methods: Twenty-four healthy adults were recruited for this study. The subjects performed squat exercise with median weight bearing, lateral weight bearing and non-changed weight bearing. The muscle activities of the vastus medialis oblique and the vastus lateralis were measured during the squat for all three conditions. The measured data were analyzed using one-way ANOVA to investigate the effect of muscle activation on the each condition. The statistical analyses were performed using SPSS ver. 17.0, and a p-value of less than 0.05 was considered significant for all cases. A post-hoc test was performed using Tukey's test. Results: The study showed that the vastus medialis oblique and the vastus lateralis ratio significantly changed according to the voluntary change of weight bearing during a squat. The vastus medialis oblique and the vastus lateralis ratio significantly decreased under the condition of voluntary lateral weight bearing. Conclusion: We suggest squat exercise on median weight bearing to increase the vastus medialis oblique and the vastus lateralis ratio. If your patient has.

  • The study was conducted to investigate the effect of soybean meal (SBM) supplementation on the voluntary intake of rice straw and ruminal fermentation characteristics. Balance trials were conducted with three Hapanese Corriedale wethers fed a rice straw alone (control), rice straw supplemented with 75 and 150 g of SBM/day in a $3{\times}3$ latin square design. Voluntary intake of rice straw in sheep fed both levels of SBM supplemented diets was significantly higher (p<0.05) than that in sheep fed control diet. Crude protein digestibility was significantly increased (p<0.05), but organic matter, crude fibre, neutral detergent fibre and acid detergent fibre digestibilities were not affected by SBM supplementation. Nitrogen balance was positive in sheep on both levels of SBM supplemented diets, but negative in animals on the control diet. Rumen ammonia and blood urea-nitrogen concentrations increased (p<0.05) as increasing level of SBM. Total volatile fatty acids, acetate, propionate, butyrate and valerate concentrations in rumen fluid were also significantly increased (p<0.01), but ruminal pH was decreased (p<0.05) by SBM supplementation.

  • The reproducibility of initial value and change over time of surface EMG spike variables(MSA, MSF, MSS, MSD) was investigated in the biceps brachii muscle of 11 healthy subjects. Surface EMG signals were recorded during sustained isometric voluntary contractions for 30 seconds at three contraction levels, 20%, 50%, and 80%MVC, respectively. Each contraction was repeated three times in each of three different days for a total of nine contractions and 99 contractions per %MVC level across the eleven subjects. A total of 297 EMG signals across the different trials, days, subjects, and %MVC levels was saved for the subsequent analysis. The degree of reproducibility was investigated using the intraclass correlation coefficient(ICC) and the standard error of the mean(SEM) based upon the analysis of variance(ANOVA), Results for intercept showed higher reproducibility of the spike variables with about 60%-98% ICC than the variable(ARV, MNF) which had been analyzed before in other researches. And results for slope showed poor reproducibility of the spike variables with about 30%-70% ICC and they were comparable with the variables of other researches.

  • The effects of erythrosine on motility of frog heart, rabbit duodenum and uterus isolated, and on mice intestinal motility and voluntary activity were investigated. The effect of erythrosine $2.3{\times}10^{-5}M$ on isolated frog heart showed a slight decrease of the amplitude of motility, and the heart motility stopped in $3.5{\times}10^{-4}M$. With the administration of erythrosine $3.4{\times}10^{-4}M$, the isolated rabbit duodenum showed a remarkable contraction and this effect was inhibited by atropine $1.4{\times}10^{-7}M$. The administration of erythrosine $2.3{\times}10^{-3}M$, produced a contractile effect on the isolated rabbit uterus, and the motility of $6.9{\times}10^{-3}M$ started to increase in contractions at first and finally stopped, keeping in continuous contractions. The effects of erythrosine 0.5, 1.0, 10, and 20mg/kg on mice intestinal motility were not significantly different from this of the normal control. With 20 and 40mg/kg of erythrosine, the effects on voluntary activity showed the decrease of 21 and 58% respectively, and voluntary activity of the mice pretreated with erythrosine 20 and 40mg/kg, induced by C. N. B. 30mg/kg showed the decrease of 57 and 78% respectively in contrast with the normal control group.

  • Purpose - The purpose of this paper is to investigate the determinants of corporate anti-corruption practice disclosure (ACPD) from the perspective of rent-seeking theory. Research design, data, and methodology - Data are hand-collected from corporate social responsibility reports (CSRR) issued by 724 A-share listed firms in China. This paper provides an empirical analysis of the relationship between ownership structure and corporate ACPD as well as its moderating role in the institutional environment. Results - Our findings indicate that rent-seeking is a key factor in influencing corporate ACPD. State-owned enterprises disclose significantly more anti-corruption information than private ones in order to achieve personal promotion of top executives. Monopoly enterprises reported significantly less anti-corruption information than enterprises in competitive industries due to their rent-seeking behavior. The reduction of government intervention and improvement of legal environment are helpful to curb corporate rent-seeking activities and enhance the level of corporate ACPD. Conclusions - Rent-seeking is an important factor in explaining corporate voluntary disclosure in emerging countries. Institutional environment also plays a moderating role in the relationship between ownership structure and corporate voluntary disclosure. Our results are of interest to policy makers, regulators and market participants that are interested in corporate voluntary disclosure and corruption prevention.

  • This study is aimed at exploring the experience of couples choosing not to have children after marriage. To identify the motives for voluntary childlessness and social perceptions, a qualitative research method was used for analysis. After in-depth interviews were conducted with 15 childless couples who had agreed to participate in the research, 15 meaning units, 5 categories, and 3 topics were established. The research findings were categorized as follows: 'the motives for being childless', 'the surrounding response and coping response', and 'the expectation of a childless family's society.' The research participants argued that families without children should be fully accepted in the changing society, with the hope that their childlessness would be respected. The significance of this study is that it focused on the perceptions of families and society, while steering away from personal views on the meaning of a life absent of children. Based on the perception that childlessness is not only a personal matter but also a social issue, this study clearly showed a variety of reactions to childless couples, such as the labeling of them as eccentric people and disapproval of them. Furthermore, this study has elaborated on the personal experience of childless couples by clearly indicating their desires to seek government support and compensation.
