The self-adaptation of software systems is a complex process that depends on several factors that can change during the system operational lifetime. But, Today's workflow management systems are only applicable in a secure and safe manner if the business process to be supported is well-structured and there is no need for ad hoc deviations at runtime. Hence, it is necessary to define mechanisms for providing a self-adaptive system the capability of reconfiguration during run-time the process that controls its adaptation. In this paper, we provide rapid dynamic reconfiguration using the workflow based on goal-scenario as the basis to set up strategies in accordance with the adaptive judgment. Also, we provide a sophisticated approach which fosters learning from past process changes by process variants through the order matrix. We present a formal foundation for the support of dynamic structural workflow changes of running. Our approach uses estimates based goal-scenario to determine which remaining parts of running workflows are affected by the external environment and is able to predictively perform suitable adaptation. This helps to ensure that necessary adaptation are performed in time with minimal user interaction which is especially valuable in change of external environment. © 2013 Springer Science+Business Media New York.

Objective: The purpose of this study was to examine the feasibility of core stabilization exercise with real-time feedback on balance and gait function in patients with chronic hemiparetic stroke. Methods: Nineteen stroke subjects were enrolled in this study. The patients were randomly divided into the experimental (n = 10) and control groups (n = 9). Subjects in the experimental group performed core stabilization exercise with real-time feedback training for 30 minutes per day during a period of six weeks. Subjects in the control group performed core stabilization exercise during the same period. This study assessed the kinematic parameters using a portable walkway system, and timed up-and-go test. Results: Gait velocity showed significantly greater improvement in the experimental group (7.3 ± 5.0 sec) than in the control group (-0.7 ± 10.6). Stride length showed significantly greater increase in the experimental group (13.2 ± 7.9 on the affected side and 12.6 ± 8.0 on the less affected side) than the control group (3.5 ± 8.7 on the affected side and 3.4 ± 8.5 on the less affected side). After training, change in results on the timed up and go test was significantly greater in the experimental group than in the control group. Conclusion: Core stabilization exercise using real-time feedback produces greater improvement in gait performance in chronic hemiparetic stroke patients than core stabilization exercise only. © 2014 - IOS Press.

According to parallel computing technology, Cloud service is popular, and it is easy to use Cloud service at everywhere. Cloud means involving application systems that are executed within the cloud and operated via the internet enabled devices. Cloud computing does not rely on the use of cloud storage as it will be removed upon users download action. Clouds can be classified as public, private and hybrid. Cloud service comes up with Ubiquitous; Cloud service users can use their service at anywhere at any time. It is convenient. However, there is a tradeoff. If user’s username and password are compromised, user’s cloud system is in danger, and their confidential information will be in jeopardy. At anywhere and anytime with any device, Cloud user’s credential could be in jeopardy. Security concerns in Cloud play a major role. It is the biggest obstacle to developing in Cloud. However, Cloud is still popular and vulnerability for hacking because of one channel user authentication. Therefore, this research proposes two-channel user authentication by using USB to emphasise security. © 2015 Springer-Verlag France

Yang, S-W. Assessment of professional baseball players aerobic exercise performance depending on their positions. J Strength Cond Res 28(11): 3289-3292, 2014-This study reports the average and SD of professional baseball players' cardiorespiratory endurance, maximum oxygen consumption, oxygen consumption during anaerobic threshold, maximum oxygen consumption of anaerobic threshold %, maximum heart rate, and heart rate of anaerobic threshold. We also report the comparison between pitchers and fielders. Considering the total number of results, percentile was used and results were classified into 5 grades. One professional baseball players' organization with more than 14 years of experience participated in this study. First, we observed that the average pitchers' VO2max was 53.64 ml·kg-1·min-1, whereas the average fielders' was 52.30 ml·kg-1·min-1. These values were lower than other sports players. Second, in case of the VO2AT, pitchers showed 39.35 ml·kg-1·min21 and fielders showed 39.96 ml·kg-1·min21. %VO2AT showed a significant difference of 71.13% between pitchers and fielders-pitchers, whereas fielders showed 73.89% (p < 0.01). Third maximal heart rates were measured at 188.69 b·min21 (pitchers) and 187.79 b·min-1 (fielders). These were lower than college baseball players and higher than other sports players. In conclusion, both professional baseball pitchers and fielders should be aware of the necessity of systematic cardiorespiratory endurance data analysis. Moreover, baseball teams, athletic trainers, and coaches should also be aware of the importance of cardiorespiratory endurance.

Purpose: The purpose of this study is to examine how nutrients can affect the relationship between the development of metabolic syndrome (MS) and socioeconomic factors. Methods: This study was based on data obtained from the 2005 Korea National Health and Nutrition Examination Survey was conducted as a health survey of nationally representative samples of non-institutionalized Korean. The final sample was composed of 3146 people over 40 years of age. Results: The relationship between the prevalence of MS and socioeconomic factors was associated with the consumption of nutrients. The slope of the graphs increased sequentially from the 1st quintile to 5th quintile of nutrient consumption. However, the directions of the 4th and 5th quintile were reversed from that of the 1st, 2nd, and 3rd quintile in reference to the horizontal axis. That is, the 1st, 2nd, and 3rd quintiles indicate that higher household income was associated with lower prevalence of MS. However, the plots for the 4th and 5th quintile indicate that higher the household income was associated with higher the prevalence of MS. This tendency was shown in all the models that yielded statistically significant confirmation of moderating effects. Conclusions: The association between the prevalence of MS and different socioeconomic status varies according to the level of nutrient consumption. © 2011 Elsevier Inc.
