Propose: The thyroid hormones (T3, TSH, T4, and FT4) play a role in energy balance and regulation of energy expenditure. The aim present study to investigate the effect of moderate intensity aerobic training on thyroid hormone levels in inactive girls. Method: A total 30 inactive girls students were randomly selected and divided to training group (n=15) and control group (n=15). The training group doing research protocol for four week (three session per week of 70% maximal heart rate), also the control group was not intervened during the study. However, elevation anthropometric index before protocol training study. Blood samples were collected 24 hours before the first and after the last training session. For analysis data used T-test at significant level p<0.05. Results: Results showed a significant reduction of T3 (P<0.05), but no significant change were observed at T4, TSH, FT4 levels after training (P˃0.05). Conclusions: Our results showed that moderate aerobic training of 70% maximal heart rate have minimum effect on thyroid hormones in inactive adolescent girls.

Purpose: The examination, investigating and relationship between costs, benefit and attachment to the environment by mediating behavioral attitudes among sports tourists. Method: The population of the study consisted of all sports spectators of 27th Fajr Open and Esteghlal vs. Tractor rematch from 15th Persian Gulf Pro League. According to Kukran formula sample size was equal to 722 persons. 920 questionnaires distributed among population that 722 questionnaires were analyzed. In order to collect data a self-made questionnaire was used which it's validity confirmed by 5 sports teachers of Razi and Tehran university and variables reliability was calculated by using Cronbach's alpha coefficient which was equal to 0.89. Data analysis done by using the descriptive and inferential statistics include Kolmogorov–Smirnov, Pearson correlation, path analysis of structural equations, Regression and also AMOS-21 and SPSS-22. The results showed that environmental communication should be formed within the right framework, encourage people to Environmentally Responsible Behavior through a bonus is not necessarily effective and doesn't encourage sports spectator. Results: Result showed that spectators display more cooperation through targeting for enjoyment and are sensitive toward any perceived cost in the implementation of Environmentally Responsible Behavior. The result also showed if cooperation with Environmental Management System doesn't take too much time and totally doesn't interfere with their enjoyment of watching match, they will support it automatically. The results also suggest the need to design efficient equipment to ensure ease of use and as a result reducing the perceived cost associated with Environmentally Responsible Behavior. Conclusions: Sports event owners can encourage spectators to do the Environmentally Responsible Behavior by connecting with them and also induce this fact to spectators that associate with the event can assist them to experience higher quality events in the future.

The purpose of this study is to provide a comprehensive model for the assignment of unfinished construction projects with their economicization approach. This research was conducted qualitatively with the data theory of the foundation. For this purpose, a researcher with 26 experts and specialists in the fields of Management and Planning Organization, the Majlis Research Center and the provincial civil affairs department coordination that purposive sampling (snowball) were interviewed. The text of the interviews was uploaded in MAXQDA10 software and then open coded using the software. After extracting the codes, the main categories were extracted using axial coding. Then, by discovering the relationship between the central categories, and then by performing selective coding and identifying the central category, the desired model based on data theory is presented as a paradigm. The results of data analysis in the form of a template are: Underlying conditions (classification of unfinished construction projects, their economization and assignment of unfinished construction projects), causal conditions (the first step is to control and limit the approval of new projects, the next step is to classify and present a schedule, economic For all incomplete development projects and transfers based on the existing legal instruments of transfers and participation), intervention conditions (lack of proper use of the capacities of existing laws and failure to specify the general policy law of the forty-fourth principle in the transfer of projects, lack of Effective entry of the Privatization Organization due to the difficulties of assigning development projects to companies, lack of accurate information on development projects of state-owned companies and provincial projects, between the systemic nature of the issue and the unclear method of pricing projects), strategies (codification of legal prerequisites, preparation of regulations and systems related to the transfer, preparation of a list of the most probable cases of transferable projects, coordination of responsible bodies due to the inter-institutional nature of the issue and determination of prices through auctions, negotiations, etc. Depending on the application of each method) and the outcome (creating sufficient motivation for managers, operators and current stakeholders of projects and projects by creating a method of returning the saved resources from investment with the participation of the private sector, aggregation and refinement A set of relevant and effective regulations and the availability of all laws and regulations governing private sector investment in development projects, the dissemination of information on all projects in the electronic system and public access to all investable applications as well as contract terms and all subsequent contract developments. The entire duration of the construction, operation or transfer, full transparency of the transfer process to reduce rent-seeking behaviors and pave the way for private sector activity).
