Abstract
Aims: Health-promoting behaviors have a major role in healthcare. The present study was conducted to assess health-promoting behaviors and its related factors in Iranian female household heads based on Pender's model.
Materials & Methods: The present cross-sectional study recruited 106 female household heads selected according to census sampling from Gonabad Health Centers, eastern Iran, from January to August in 2015. Data were collected using the Health-Promoting Lifestyle Profile-II (HPLP-II) and a researcher-made cognitive and emotional factors questionnaire based on Pender's model. Data were analyzed by SPSS 16, using descriptive and analytical tests, including ANOVA and independent student t-test.
Findings: Participants' statistical mean age was 40.16±7.21 years, and most of them (61 women, 57.5%) were widowed and the rest were divorced. The statistical mean score of health-promoting behaviors was 123.16±20.42, in moderate level, and showed significant relationships with cognitive and emotional factors of self-efficacy, barriers, and interpersonal relationships (p<0.05). Among health-promoting behaviors, spiritual growth had the highest Statistical mean score (24.91±5.3), and physical activity (12.83±3.5) and stress management (17.83±3.9) the lowest mean score.
Conclusion: Health-promoting behaviors in Iranian female household heads need improvement. The results can be used by these women and the healthcare system to identify related factors and develop interventions for modifying health-promoting lifestyles.

Abstract
The aim of study it was carried out survey investigation of consumer attitudes toward organic agriculture. The study was a kind of applied and descriptive –correlational method. The research population was consumers of agricultural products in Alborz Province. Sample size was determine by Cochran's formula (n= 250). Proportional stratified random sampling method was used. Data was collected through an instrument that developed by researcher. Validity estimated by a panel of experts in University and Agriculture experts’ of jihad-e- keshavarzi department of Karaj city. Reliability was conducted by a Pilot test and Cronbach’s alpha coefficient assumed (0/75) which show its suit for research conduct. Data analysis was performed using SPSS software package. Research findings show that there is a significant difference between responces in diploma and graduate & post graduted level at the 0.05 level. Also there is positive relation between consume obstacle and factors affecting to use of organice agriculture with responcendents attitude.

Abstract
Advocating the inclusion of neurocognitive science concepts in English language teacher training curriculum is gaining more interest. However, little is known about the prospective teachers' perceptions of neurocognitive science core concepts. The purpose of this phenomenological study was to explore the prospective ELT teachers' perceptions of the neurocognitive core concepts and the applications of them through the lens of four neuro-educational models in the classroom practices. Fifteen prospective Iranian ELT teachers were interviewed and the data were analyzed using the phenomenological method. The findings revealed that the prospective ELT teachers lacked a clear understanding of the neurocognitive concepts and their implications in classroom practices. The findings support the inclusion of neurocognitive science core concepts training in language teachers' professional development.

Abstract Selecting a portfolio has always been a significant issue in Financial Management. The models presented for selecting the best portfolio have some deficiencies and after some time, their deficiencies would be revealed and they will be replaced by some other models. One of the problems with those models is neglecting the multifaceted indices and dimensions for final evaluation of portfolio, and these efficiencies will bring the validity of the evaluation results under question. In order to remove these efficiencies, one can use DEA (Data Envelopment Analysis) technique which is one of the MCDM (Multi-Criteria Decision Making) techniques. In this paper, two models have been presented; one finds the most efficient portfolio and the other one finds the most inefficient. In this paper, 95 companies now present in Tehran Stock Market have been investigated. The results demonstrate that out of those 95 companies, seven companies are efficient and 8 companies are utterly inefficient.

Abstract
Most of the time, Groups/Communities are involved in negotiations and disputations due to their various interests. They are always trying to pursuit their aspiration to embrace changes and influence on events. Although sometimes these groups are not completely opposed to each other and their intention is just to get the desired results, almost always their conditions are in contrast with each other. These conflicts prevent negotiators from approaching desired acceptable solutions. For improving the negotiations, resolving the conflicts and reaching satisfactory decisions, Drama theory is applied. This theory is based on game theory. In this paper, Iran Nuclear talks with 5+1 Group will be discussed as an applicable case for drama theory.

Abstract
The aim of this paper was to evaluate the impacts of International Corporate Entrepreneurship (ICE) on general performance in Halal Food Industry, with moderating part of global environmental hostility. Our data comprised of 250 firms working in Halal Food Industry in Iran and they were studied utilizing the structural equation modeling. According to the results, the firms exploit ICE activities by accomplishing higher general performance in addition to promoting export and financial performance. The results underscore the significance of ICE for organizational achievement, both in general and in foreign markets. Also, the results suggest that the perceived nature of its environmental condition, especially hostility, will affect the link between ICE and performance fundamentally. This study explored the relationship between ICE and firm performance along with the role of hostility at the international environment in this relationship. The findings of this study help bridge the gap in the literature by assessing the impact of ICE on an organization's general performance with the hostilities at the international scale playing a moderating role in this regard. This paper makes huge contribution to the current works by exploring the connection between ICE, firm performance, and global environmental hostility.

Abstract
The flow forming process is widely used in the production of axisymmetric industrial parts. The advantage of the flow forming process over other manufacturing methods is the use of simple tooling, reduced forming loads due to localized deformation, and enhanced mechanical properties and surface quality of finished parts. In this research, the warm flow forming process of AA6061-O aluminum alloy has been investigated for the first time. For this purpose, laboratory equipment and samples were designed and fabricated. In this study, the effect of temperature, thickness reduction, and number of passes (number of forming steps) on dimensional accuracy (thickness variation) and mechanical properties of warm flow formed AA6061-O alloys pipes have been experimentally investigated. The experimental results show that flow forming increases the strength and decreases the ductility of the formed pipe at all process levels compared to the initial non-flow forming pipe. However, the ductility of the pipe increases and its strength and microhardness decrease by increasing the forming temperature from 20 to 300 ° C. While with increasing the percentage of thickness reduction from 20% to 60% at a constant forming temperature, the strength and micro-hardness of the warm flow-formed pipe increases and its ductility decreases.
