Abstract
Aim: Health-promoting lifestyle (HPL) not only prevents diseases but also improves the individual’s general health and well-being. Global burden of women’s health problem in the postpartum period is enormous while few studies have been undertaken to examine the role of parity difference in women's lifestyle. The aim of this study was to assess the effect of parity on HPL among women in the first year after childbirth.
Methods: This cross-sectional study was performed in governmental health centers in Zanjan (Iran) in 2016 on 310 women. A proportionate stratified random sampling technique was used to select the participants. The questionnaire consisted of two parts; the first part assessed the socio-demographic and obstetric characteristics, and the second part was the “Health Promotion Lifestyle Profile II” (HPLP II). The data were analyzed using the SPSS software (ver. 22). Data analysis included the percentage, arithmetic average, and ANOVA tests.
Findings: The results showed that 53.9% of the women had one parity, 36.1% had two parities, and 10% had three and above parities. The mean total HPLP II was 131.28±15.37. The highest and lowest mean scores were dedicated to spiritual growth (25.64±4.50) and physical activity (14.68±3.41) domains, respectively. The women who had two parities had a higher score in health responsibility (25.63±4.39) and physical activity (15.41±3.66) domains than the other groups.
Conclusion: The health behavior of women was moderate. A statistically significant correlation was found between the number of parities and the health responsibility, nutrition, and physical activity, which are the domains of HPL.

Abstract
Aims: Cardiovascular Diseases (CVDs) are the main causes of death and have the first place among other diseases throughout the world. Studying the situation of risk factors for CVDs seems necessary in Iran at various periods. The aim of this study was to determine risk factors for cardiovascular diseases (CVD) among the employees of Ilam University of Medical Sciences in order to design appropriate educational interventions.
Materials and Methods: In this descriptive cross-sectional study, which was conducted in 2017, 294 employees of Ilam University of Medical Sciences participated after presenting written consent forms. To collect data, a researcher-made questionnaire was designed and applied after verifying the validity and reliability (Cronbach’s alpha greater than 0.8). Eventually, the data were analyzed, using SPSS 16 and appropriate statistical methods.
Findings: Generally, 46.3% of the participants had a history of CVDs, 21.8% had a history of death caused by these diseases in their family, and 69.4% had a history of death caused by CVD among their relatives; 72.4% of the participants did not exercise daily and the mean daily exercise of participants was 8.08±1.51 minutes. Totally, 41.5% of the participants were taking solid oil, 78.6% were high-fat dairy consumers, and 41.2% consumed red meat more than twice a week.
Conclusion: Performance of the participants in terms of physical activity and consuming fruits and vegetables, fish, red meat, and fatty foods is undesirable, indicating the unhealthy lifestyle of people and their exposure to CVDs.

Abstract
Aims: This study aimed to determine the relationship between the constructs of Health Belief Model (HBM) and doing daily exercise to prevent cardiovascular diseases (CVDs) among the employees of Ilam University of medical sciences in Iran.
Instrument & Methods: About 294 employees of Ilam University of medical sciences participated in this cross-sectional study after providing a written consent form in 2017. The tool to collect data was an HBM-ISCS questionnaire, which was applied. Eventually, the obtained data were analyzed using SPSS 16 and logistic regression.
Findings: The results showed that 72.4% of participants did not exercise daily, and the Mean±SD of their daily exercise was 8.08±1.51min. Logistic regression showed that the possibility of daily exercise per unit of increase in perceived barriers decreased by about 10%, while every unit of increase in the self-efficacy score resulted in the possibility of 1.12 times more doing daily exercise. The possibility of doing daily exercise among men was 2 times more than in women, and among the personnel of financial/administrative department, it was about 2.5 times more than in the employees of health care department. Accordingly, the possibility of doing exercise decreased by about 8% per unit of increase in work experience.
Conclusion: The amount of doing daily exercise among the participants of this study was low, and implementing interventions commensurate with the results of this study and based on HBM can be effective in improving the amount of doing daily exercise in them.

Abstract
Aims: Physical inactivity and a sedentary lifestyle increase the risk of all-cause mortality. This study aimed to assess the impact of a theory-based education on PA among female health volunteers in Iran by applying the Theory of Planned Behavior.
Materials & Methods: This randomized controlled trial was conducted on female health volunteers in Shushtar, Iran, from March to December 2016. One hundred ten participants were selected by purposive sampling, and they were randomized into intervention and control groups based on a 1:1 ratio in a single block. The intervention included three educational sessions and a walking program. A multi-section questionnaire containing items on TPB constructs, the international physical activity questionnaire, and the physiological cost index (PCI- an objective measure of PA) was used to collect the data at baseline and six-month follow-up assessments. Then the data were compared within and between groups using t-test and paired test using SPSS 19 software.
Findings: All 110 ‘Health Volunteers’ (55 in each group) were entered into the study. The mean±SD age of participants was 35.65±10.25 years. The results obtained from the analysis showed that the educational program improved attitude towards PA, perceived behavioral control, intention, behavior, and PCI among the intervention group (p<0.001). However, no significant changes occurred in the control group regarding the study variables (p>0.05).
Conclusion: The TPB-directed educational program improved physical activity and physiological cost index. The study framework might be used as a practical template for interventions aimed at improving physical activity among female health volunteers.

Abstract
Aims: This protocol aims to design and evaluate an educational program to promote weight management among preschoolers.
Designed Methods: This study has a sequential mixed-methods approach in two phases: qualitative and quantitative. In the first phase, epidemiological, educational, and ecological factors of the PRECEDE-PROCEED model influencing weight management promotion among Tehranian preschoolers will be explored. Seventeen preschoolers' parents and two preschool principals were interviewed by the researcher in the preschool setting. After data analysis through directed content analysis, a one-group pre and post pilot study will be performed in phase two. Fifteen mother-children dyads will be enrolled, and mothers will be asked to complete four questionnaires and measure children's weight and height. Then an educational program will be designed to promote weight management among preschoolers based on the results of the qualitative phase and a pre-test stage. Post-test will be performed immediately and three months after the intervention.
Expected Findings: In phase one, we expect facilities and barriers of preschoolers' weight management to be identified based on social-cultural conditions and the structures of the model. According to the qualitative study results, an educational program will be developed and evaluated in phase two, and it is anticipated that the educational program will positively influence children's weight management.
Conclusion: In the various communities, cultural and social differences have a critical effect on obesity in preschoolers; therefore, examining these factors can help understand individuals' views and interventional design programs to solve this problem.

Abstract
Aims: Present study aimed to investigate the exposure of the population covered by Iranian health insurance to the catastrophic cost of health.
Instrument & Methods: This cross-sectional study was performed on household income expenditure data. The sample included 20,764 households. The model of the World Health Organization was employed to measure the catastrophic cost of health. Data were analyzed by Stata 14.
Findings: From the total sample studied, 4.89% of households were faced with a catastrophic cost of health. The findings show that female-headed households are more likely to incur catastrophic costs. Some levels of education of the head of the household reduced the likelihood of incurring a catastrophic cost. Unemployed households and other occupations were significantly more costly. The results of the analysis also indicated that using dental services has a positive and significant effect on households facing catastrophic health costs. The chances of facing the catastrophic cost of health in the fourth, fifth, and sixth decades were significantly higher than those of other income decades.
Conclusion: The results of the study showed that Iran's health insurance coverage has not been able to fully protect the insured from the catastrophic costs of health. Improving the livelihood of the community along with paying special attention to vulnerable families and patients with special diseases will play an important role in reducing this index in the insured of the Iranian Health Insurance Organization.

Abstract
Plant growth is often limited by low levels of soil micronutrients such as copper (Cu), especially in calcareous salt-affected soils of arid and semiarid regions. The aim of this work was to investigate individual and combined effects of salinity and Cu on growth, leaf relative water content (LRWC), cell membrane permeability, lipid peroxidation, and total phenolic content (TPC) of rosemary (Rosmarinus officinalis L.) in a hydroponic experiment. A factorial arranged experiment with three salinity levels (i.e., 0, 50, and 100 mM NaCl), and three levels of copper (i.e., 0, 0.5, and 1.0 µM Cu2+, as CuSO4) was performed. The salt stress led to a significant decrease in leaf relative water content especially at 0 µM Cu2+. Salt treatments (50 and 100 mM) were found to increase electrolyte leakage and malonyldialdehyde content of rosemary; however, this increase was greater at 0 µM than 1.0 µM Cu2+. Regardless of Cu treatments, salinity (50 and 100 mM) induced significant increases in TPC by 13 and 29%, respectively. The application of 1.0 M Cu at the 50 mM NaCl treatments increased total phenolic content by 19% compared to 0M Cu. Copper nutrition resulted in greater accumulation of phenolic compounds in plant roots and thereby decreasing lipid peroxidation under salt stress conditions.

Abstract
Salinity is among important soil stresses adversely affecting the process of nitrogen (N) fixation in leguminous plants in different parts of the world. It has been indicated that salinity can inhibit the early stages of nodulation process between bacterium and the host plant including the exchange of signal molecules (nod gene inducers). There has not been any research regarding the effects of nod gene inducers on the growth of alfalfa inoculated with Sinorhizobium meliloti under saline conditions. A growth chamber experiment was conducted to determine the effects of pre-incubation of S. meliloti with effective inducers of nod genes Luteolin, Methyl jasmonate and Genistein on the growth and N-fixation of two different alfalfa (Medicago sativa L.) cultivars (Yazdi and Hamedani) under salt stress. Nod gene inducers increased alfalfa growth and N fixation under normal as well as under salt stressed conditions. Yazdi cultivar showed to be more tolerant to salinity than Hamedani with a higher growth rate and N fixation. Luteolin was the most effective nod gene inducer on plant growth and N fixation under normal and as well under salt stressed conditions. The results suggest that pre-incubation of S. meliloti with effective nod gene inducers can improve alfalfa growth and N fixation under salinity stress.

Abstract
Orthopedic implants are one of the most reliable methods for bone injuries treatment. An important issue, which must be considered in the design of orthopedic implants, is that the Young's modulus of implants should be near to the host bone to prevent complications such as stress shielding. Porous implants are considered as one of the new and effective methods for this issue and recent technologies such as metal 3D printing made it possible to manufacture different porous structures with various geometries, which could be used to reach the goal. Porous geometries are used to approaching the elastic modulus of implantation with a porous structure to the bone. Mechanical properties of Diamond porous structure have been investigated in this study and an equation for obtaining the modulus of elasticity is presented in terms of the geometric parameters of this structure. Based on the results, the error between finite element analysis and experimental data is between 3.64% and 18.51% and it has been shown that the Young's modulus obtained from finite element method is more in line with the existing experimental data than the analytical results; by the increase of relative density, the error would be decreased. Furthermore, in the relative density between 0.06 and 0.16, the Young's modulus of titanium Diamond structure would be the same as bone Young’s modulus, which is an effective feature in design of orthopedic implants.

Abstract
At first glance, myths are considered as the old stories but, the truth is that they are the product of a way of man’s wise thinking which have survived in the form of narration and action. Ad the myths answer to the man’s needs of world-knowing , they continue living, in the modern world and by the help of science, through accordance with the mental frames of man.
One of the newest fields that benefiting from its capacities help in myth renovation is internet technology. The spread of this wide web has changed it to a modern environment. The subject of digital body in this new environment and its capacities on achieving the collective goals set the ground for the formation of mythical meanings and concepts which challenge the scientific wisdom.
Therefore, this research analyzes the capacities of this media in developing the new mythical concepts based on the contemporary myth theory of Roland Barrett and the mythical analysis of Louie Straus . The method is descriptive-analytic and based on the library resources. The results revel that in this modern environment, reality, idealism and fantasy are interwoven in the form of old archetypes and have changed the validity of many concepts. Thinking about Creation, escape from prohibition, simultaneous presence, excess of time and place, unified world, dominance over loneliness and the wishes that came true through the myths, now form a modern thinking horizon in a vital, interactive and experimental environment which renovates the myths inside this worldwide web.

Abstract
In thermal barrier coatings (TBC), surface cracks, debonding, and thickness degradation may occur during the manufacturing process or life cycle, leading to poor performance and ultimately a dangerous system failure. The main goal of non-destructive testing of thermal barrier coatings is to detect these defects and determine the health of the coating. Various non-destructive inspection methods have been proposed to evaluate thermal barrier coatings, and due to the numerous advantages of thermography, including high speed, low cost, safety, no need for direct contact, automation capability, and inspection of a large area of the part, this method has received special attention from researchers. This study will present a method for manufacturing samples with different diameters of artificial separation defects. The following is the equipment's arrangement and the sample's thermography process. It was concluded that blackening the surface of the sample by increasing the amount of thermal energy absorption increased the ability to identify separation defects and increased the signal-to-noise ratio by 257%. Finally, by implementing different filters on the recorded raw thermal images, it has been shown that in both cases the best filter in terms of SNR is the median filter and then the Gaussian filter. The background removal filter also had no noticeable effect on increasing the signal-to-noise ratio and acted as a complement to the median and Gaussian filters by reducing the fixed error

Abstract
The present tries to study and review the manner the discourse analysis method is being used in family studies. This method especially emphasizes the role of research in the social context. Considering the key role of the family and women and their place in ensuring the prosperity, this sacred institution should be researched upon in this so that we can reveal the structures and processes that are based on ideology and power. However, considering past researches in the field of women and family, a majority of researchers have paid little attention to the social context while investigating those problems. Therefore, it seems a research gap in this field and hence, this article aims to answer to this question: How can family and women's issues be investigated through the discourse analysis method? The influencing factors on this social phenomenon have been written with the aim of determining the type of linguistic strategies in representation, alienation, highlighting, etc. And in the meantime, we will also discuss the evolution of the discourse analysis method. In order to achieve this goal and to understand this matter more easily, we have used the movies Kitab Qanun (Book of Law), Abed and One Day (Forrever and One Day) as examples.
