The purpose of this study was to investigate coordination structure of infront kick in women soccer as a function of skill level. To succeed this purpose, four girls' high school students who had never experienced soccer before were selected as novices, and four girls' high school students who had played soccer for over three years as experts in this lab. To recognize the change of coordination structure according to practice, novices had practiced infront kick in soccer for two weeks. consequently they were taken films of kicking motion three times -before practice, after one week practice, after two weeks practice. However, experts were taken once. The experimental instruments for this study consisted of a video camera, reference frame. LED and APAS for digitizing. Angle to angle diagrams and phase plan portraits for qualitative analysis of coordination structure were gotten with LabVIEW 6i. The conclusions are as follow: firstly, novices' coordination structure had been changed since practice. Secondly, there were significantly different between coordination structures of experts and pre-practice novices. Lastly, there were similar between coordination structures of experts and post practice novices.

Texes are imposed through formation and decision of tax payment. There are government imposition way and self-assessment way on the decision method of tax payment, and most taxes are confirmed by self-assessment way because exuviating in traditional decision method in modern taxes. Tax payment by self-assessment system is primary decision method of the tax payer because he knows his assessment well, and reserve decision right of taxation government office to secondary or complemental position. These tax payment system by self-assessment is accepted in the U.S.A. traditionally, and say that is own imposition system in meaning that tax payment establishes oneself standard of assessment and amount of a tax. It is most situation, indeed, taking tax payment by self-assessment way individual income tax, corporate income tax, education tax, traffic tax and etc, in Korean tax system. These self-assessment system can be thought that is suitable to tax payment usage which is democratic because it establishes own tax amount, but when tax return is reported overmuch by mistake of statute etc, it creates the problem to relieve very hardly. So, when taxpayer files overpaid taxes or littleness deficit amount of money, we introduced the claim system for reassessment since 1995 to correct this in case do. This claim system for reassessment has various kinds of problems because the enforcement time is short up to now and the research is not gone abuzz. Therefore, this research examines problems of current the claim system for reassessment and compares with foreign tax laws and groped the improvement way. The improvement ways of current claim system for reassessment are as following if they list important things. First, it is problems about extension of claim period for reassessment. Current claim period for reassessment is that is within 2 years from the date the return was filed in general claim for reassessment's case, and in the case of claim for reassessment by after flare reason arrive within 2 months from a day that reason happens. This can be thought that the period is insufficient in right relief because correspond to short term. Therefore, in general claim for reassessment's case, the period must be extended within 5 years from the date the return was filed, and must be extended within 6 months from a day that reason happens encountering in the claim for reassessment by reason that is after flare. Second, it is problem about unclearable nature of reason in the claim for reassessment by reason that is after flare. Currently, in the case of the claim for reassessment by reason after flare, a analytic part that become an issue is when it cancels contract by inevitable reason, whether correspond to the reassessment claim's subject, and when it correspond to the reassessment claim's subject, inevitable reason usually intends cancellation of sum, that is deciding each differently about the reassessment claim's target in reason after flare time at time of cancellation of sum in case of transfer income tax, gift tax and acquisition tax. Third, it is problem by pleading not guilty of reassessment claim system in local tax law. Current local tax is recognizing right redress through correction report, application and so on. But the claim system for reassessment is not recognized by local tax. As such result, when taxpayer overpays local taxes through mistake, the method of the right relief is blocked effectively in that case and is implying various kinds irrational standpoint being real condition. Therefore, local tax law have to introduce not only general claim system for reassessment but also reassessment claim system by reason after flare as soon as possible.

The purpose of this study was to examine the effects of learning a hoop movement on timing and method of augmented feedback in rhythmic gymnastics. The sixty subjects (30 males & 30 females) were selected from adults (ranging from 20 to 29 years) in Seoul, Korea. The subjects were randomly assigned to 6 different conditions groups: Concurrent Visual Feedback (experimental group 1), Concurrent Visual Feedback (experimental group 2), Concurrent Visual +Verbal Feedback (experimental group 3), Terminal Visual Feedback (experimental group 4), Terminal Verbal Feedback (experimental group 5), Terminal Visual+Verbal Feedback (experimental group 6). Each experimental group participated in 5 sequential movements of hoop skill tasks, was carried out 2 (feedback timing)×3 (feedback method)×5 (block) factorial design with repeated measures on the last factor. All post hoc analyses used the Tukey's HSD for difference between motor performance and learning on timing and method of feedback. Also, retention and delayed retention stages analyzed by 3-way ANOVA. Data analyses were derived through the use of Statistical Package for Social Science (SPSS 10.0). The following results are based upon the findings of this study: 1) there were not significant differences between concurrent feedback and terminal feedback in the movement performance scores, 2) there were significant differences between visual feedback and verbal feedback in the movement performance scores and then visual feedback was higher than verbal feedback in the movement performance scores, 3) there were not significant differences between Visual feedback and mixed feedback in the movement performance scores, 4) there were significant differences between mixed feedback and verbal feedback in the movement performance scores and then mixed feedback was higher than verbal feedback in the movement performance scores, 5) there were significant differences in the blocks and according to the increase of blocks, the movement performance scores of each block became higher. In conclusion, regarding the feedback timing, there were not significant differences when the process or the end of movement performance received feedbacks. Visual or visual+verbal feedback was more effective than verbal feedback in the method of feedback.

Background: Bus drivers are known to be highly at risk of cardiovascular diseases. In this study, we assessed the cardiovascular disease prevalence of bus company employees in Seoul, South Korea, and compared the results to those of general workers. Methods: We analyzed the 2014 Korean National Health Insurance (NHI) data and defined hypertension, diabetes, dyslipidemia, ischemic heart disease, and cerebrovascular disease based on the KCD-6 medical diagnoses. We used bus company employees as surrogate participants of bus drivers due to the characteristics of Korean NHI data. We identified bus company employees in Seoul based on one’s workplace which the insurance is registered. The prevalence of five diseases was compared between the bus company employees and general workers. We also calculated the odds ratios (OR) of five diseases between the bus company employees and general workers. To compensate the vast demographical differences between the two groups, we performed propensity score matching. Results: Bus company employees have higher OR for having hypertension (OR 1.33, 95% CI: 1.28-1.39), diabetes mellitus (1.14, 95% CI: 1.08-1.22), and dyslipidemia (1.23, 95% CI: 1.17-1.29) than the general workers or propensity score matched controls. However, the OR of having ischemic heart disease were not significant. The OR of cerebrovascular disease were lower in bus company employees than in the general workers after adjusting the covariates, but similar in the propensity score matched model. Conclusion: This study showed that the ORs of cardiovascular disease risk factors are high in bus company employees when compared to the general working population. Further studies with the longitudinal design should be conducted to confirm the causal association.

Yook, Ji-Hwan,Kang, Choong-Min,Kim, Woo-Yeon The Korean Society for Applied Biological Chemistr 2016 Applied Biological Chemistry (Appl Biol Chem) Vol.59 No.5

Histone-like nucleoid structuring protein (H-NS) is a global regulator in enteric bacteria and other bacteria. It has been reported that H-NS has no modifications for its activity. Even though H-NS is called histone-like protein, it is acidic, contrary to the basic eukaryotic histones. Here, we report that there were mobility differences for various sources of H-NS seen in sodium phosphate-buffered native gel electrophoresis. We examined various native gel electrophoresis conditions using the wild-type E. coli (MG1655), three H-NS mutants (two were H-NS knockout mutants), and the E. coli BL21 overexpressing H-NS (BL21 (DE3)/pPD3).
