A universe of components like objects, persons, events, dynamical phenomena and many other strong relations between them has to be taken into account to carry out such a study as this. These form a complex system usually referred to as the Education System (ES). Therefore, the research on (ES) modelling methodology can provides as consequences strategies to foresight and planning the future development of the corresponding information technologies in (ES) named by us (ITE). At the same time, we appreciate that, indifferently of the existence domain, the performance is a measure of the risk and conversely. “Risk” is a term that was applied initially when the probabilities of the results were known objectively .Although, it was described by “the possibility of something bad”, and “uncertainty” is accepted only for the problems in which there are real alternatives with multiple possible effects. Hence, the risk is an essential element to any human project and not only. This is a new proposal to investigate and promote the Science Education following the Educational Efficiency, being based on the gradual performances and useful for all the educational systems in the world. Our study investigates and promotes the Science Education by a gradual mathematical model of the performances, following the practically verified abilities and the proper corresponding implications. It completes our previous research work [4] by the efficiency.","PeriodicalId":13729,"journal":{"name":"International Educational Scientific Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89515860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lang, K.

The focus is on TL in leukocytes and muscle tissue in middle to advanced aged subjects. Regarding item (1), a strong tendency for an increase in mean leukocyte TL was found for exercise energy expenditures up to about 2∙103 kcal/week, while for higher activity levels no conclusive statement can be made. Conversely, research on skeletal muscle TL so far is quite limited but suggests that physical exercise with prolonged eccentric muscle contractions rather acts to shorten telomeres, while sports with little eccentric contractions might rather act to lengthen telomeres. As to item (2), a model for hypothetical pathways for exercise dependent telomerase activity regulation is proposed by consolidating findings of different studies in different cells. Consistent with this pathway model, various studies report increased telomerase transcription or activation by exercise. Moreover, a qualitative overall model for endurance exercise related TL dynamics is presented. It considers telomeres as dynamic structures in equilibrium between telomere shortening (e.g., cellular turnover, oxidative stress, inflammation) and telomere lengthening (e.g., telomerase activity, telomerase recruitment) effects. A negative feedback-loop mediated by enhanced telomerase recruitment to short telomeres is assumed to counteract too excessive TL alterations. Finally, a proposal is put forth for future research on exercise dependent telomere dynamics by adopting a systems biology approach to develop mathematical models that properly integrate the complexity of the interacting variables.","PeriodicalId":13729,"journal":{"name":"International Educational Scientific Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87876024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
