This study was conducted to investigate the effects of aerobic exercises with different intensity on body composition and appetite-regulating hormones in obese middle school girls. Subjects were divided into two groups: a low-intensity group(30% HRR, n = 8) and a high-intensity group(70% HRR, n = 8). Both groups had performed a modified PACER shuttle run 40 minutes/day and 4 times/week at their intensity during 9 weeks. For the data analysis, independent and paired t test of SPSS ver 20.0 were used with the significant level of 0.05. As the results, while the low-intensity group showed a significant difference between before and after exercise training in appetite-regulating hormones, it did not in body composition. And the high-intensity group showed a significant difference in both of body composition insulin and appetite-regulating hormone. Although there were no significant difference between groups before and after exercise training, over mediumintensity exercises are considered effective in weight loss and positive changes of appetite-regulating hormones in obese middle school girls. In addition, combined exercises, including not only aerobic exercises but resistance exercises, are necessary and related researches should be conducted.

Recent studies (Chiviacowsky, & Wulf, 2002, 2005, 2007; Chiviacowsky et al., 2009; Badami et al., 2011, 2012) have shown that learner prefer to receive feedback after they believe they had a good rather than poor trial. The present study followed up on this finding and determined whether feedback is more effective when provided after good or relatively poor trials. The task required participants to putt golf balls to a target placed on the floor. They had no prior experience with the experimental task. Twenty-four elementary school children with a mean age of 10.4 years participated in this experiment. Participants randomly assigned to two groups with 12 participants in the ``KR on good trials`` and 12 in the ``KR on poor trials`` group. Data obtained from all subjects in six acquisition and two retention trials blocks were analyzed with two separate analyses of variance for each of four error scores. There was no differences in practice. However, on the retention test without KR, performed 1 day after the practice phase, the KR good group clearly had higher accuracy scores than the KR poor group. And analyses on the variable error indicated a significant interaction (group × block) during the retention phase. These results demonstrated that learning is facilitated if feedback is provided after good rather than poor trials.

This study was conducted to compare the exercise frequency rate, body composition and physical fitness of PE majors and non-major college students. The subjects were consisted of 60 college students (23 PE majors college students and 37 non-major students) of P area in Korea. The study obtains the following results. First, PE major college students showed positive results in exercise frequency rate, skeletal muscle mass, body fat percentage and basal metabolic rate than non-major students. Second, it was found that PE major college students are better than non-major students in muscular strength, muscular endurance, flexibility, agility, power and cardiorespiratory endurance. The positive aspects of the exercise have been reported in several studies but still exercise frequency rate of college students are low and their body composition and physical fitness results are worse than physical education major students. Therefore, it is expected that the reasons of their nonparticipation in exercise to be identified so that much more college students can exercise steadily.

Background/Aims: This study was designed to clarify the sequential morphologic changes of copper overloaded-rat liver. Methods: The Sprague-Dawley rats were divided into three groups according to copper and penicillamine administration: Group I. normal control injected with lipiodol; Group II, treated with copper only; Group III, treated with copper plus D-penicillamine. Liver tissues were stained with hematoxylin-eosin and rubeanic acid. In order to elucidate the ultrastructural changes of the liver, transmission electron microscopic examination was also performed. Results: Electron microscopic findings in copper-treated group were characterized by a number of copper-containing lysosomes at pericanalicular ectoplasm, normal sized and bizarre mitochondria with small vacuoles (at 2 weeks), dilated bile canaliculi with decreased microvilli (at 3 weeks), disruption of sinusoidal border (at 4 weeks), microsteatosis (at 5 weeks), a Councilman body-like inclusion in sinusoid and round hepatocytes undergone coagulation necrosis in sinusoid (at 7 weeks), increased collagen bundles in Disse space and loss of microvilli (at 12 weeks). There were increased copper containing granules in hepatocytes of copper plus D-penicillamine treated group, but normal ultrastructural findings were observed. Conclusions: These findings indicate that hepatic injury induced by copper overload is caused by deranged copper metabolism in the lysosome of the hepatocytes and administration of D-penicillamine in copper stressed rats seems to be effective for the restoration of hepatocyte function and morphologic changes.
