 Domestic violence against women is prevalent. It has personal, social, physical, and spiritual effects on women. It is necessary for women to be aware of domestic violence. This study aimed to determine married women's awareness and attitude toward domestic violence in Kerman City, Iran.

 This cross-sectional study was conducted on women referring to the comprehensive health centers of Kerman city, Iran in 2022, using Convenience sampling method. The self-administer questionnaire consisting of two sections containing demographic data and valid and reliable questionnaire on domestic violence against women was completed. Data was analyzed using SPSS version 20. Descriptive indicators including mean, standard deviation, and frequency were used to description. Data analysis was done using non-parametrictests including Kruskal-Wallis and Spearman's correlation tests.

 The mean score of awareness regarding violence against women was 8.46 (range: -14 to 14) and the mean score of attitude was 25.12 (range: 5 to 40) in this study. There was a significant negative relationship between the attitude score and the individual's age (P>0.05), the spouse's age (P<0.001), and the number of children (P<0.001). There was a significant relationship between the level of education and the score of awareness (P=0.015) and attitude (P=0.016). Also, there was a significant relationship between the spouse's education level and the knowledge score (P<0.001), and the attitude (P=0.019) score. The person's occupation had a significant relationship with the knowledge score (P=0.001) and attitude score (P=0.003).

Comprehensive policies should be implemented to empower women by educating them about domestic violence and encouraging them to be more active in the community. A higher level of education and having the job is also important

In this study, graphene oxide is functionalized with benzidine and zinc oxide nanoparticles to improve adhesion and corrosion resistance properties. Nanoparticles were dispersed in an epoxy-based coating and applied as a coating on steel panels. The corrosion resistance of nano composite coatings was evaluated by salt spray test during 45 days of exposure. The results showed that the anti-corrosion performance of the coating containing 0.01% graphene oxide containing amine-zinc oxide with a penetration depth of 1.2 mm from scratch showed the highest corrosion resistance. The results of the salt spray and EIS tests show that with the increase of nanoparticles up to 0.01%, the anti-corrosion properties increased.

By varying the level of graphene's surface oxidation in this paper, the thickness of the interphase region was altered, and its influence on the conductivity was investigated. Due to the similarity of water-based epoxy chemical groups with graphene oxide oxygen groups, the interphase region was reinforced. Infrared spectroscopy and thermal gravimetry were performed to evaluate the graphene oxide synthesis, and Raman spectroscopy was also performed to investigate the structural defects on graphene sheets. At first glance, based on the interphase region theory, it is expected that by increasing the oxidation rate of graphene nanosheets, the electrical conductivity of polymeric coatings will increase, and the percolation threshold will decrease. On the other hand, due to increased oxidation, the structural defect on graphene nanosheets increases, and the conductivity of the coatings is expected to decrease. Due to the opposite effect of the two factors mentioned above, the effectiveness of nanocomposite samples was studied, and the impressment of each factor was investigated in this project.

Today, in near-to-nature forestry, biodiversity conservation, with emphasis on forests conservation, as a valuable genetic resource, has received much attention. Deadwood, as a habitat, plays a key role in diversity and abundance of saproxylic fungi in forest ecosystems. The uncontrolled exploitation, and the management programs applied in forests, have significantly reduced the deadwood volumes and diversity, jeopardizing diversity and abundance of saproxylic fungi. In this study, 29 saproxylic fungal species belonging to 15 families from the phylum Basidiomycota were collected from Asalem forest, Guilan province, northern Iran. The recovered species were identified based upon their morphological characters, using available identification keys. The results showed that the family Polyporaceae (31%) and the species Trametes versicolor (18.4%) have the highest abundance between other families and identified species, respectively. The importance of saproxylic fungi, introduction of deadwood, as a habitat and a key factor in biodiversity of saproxylic fungi in forest ecosystems, have also been discussed.

Balance is a vital element in children with cerebral palsy and it is important to choose effective exercise strategies to achieve it. In order to investigate the balance of children with cerebral palsy, physical activity and virtual reality intervention were used. The pre-test post-test design with control group and follow-up test on 15 children with spastic cerebral palsy (hemiplegia) (6-12 years) from Golha Special School in Shiraz was used. Samples were randomly divided into two experimental groups: physical activity (n = 5) with aerobic exercise program, balance skills, ball skills and virtual reality using Xbox kinetic system program (n = 5) and control group with no intervention exercises (n = 5). Experimental interventions were performed in experimental groups for 8 weeks, 3 sessions per week. In order to assess balance, Pediatric Balance Scale of children was used in pre-test (two weeks before and one day before intervention), post-test (one day after intervention) and post-test (4 weeks after the post-test). One-way ANCOVA and Bonferroni post hoc tests were used for statistical analysis and the significance level was considered 0.05 at 0.05. There was a statistically significant improvement in the balance of children in the experimental groups compared to the control and virtual reality superiority to the physical activity group. As a result, virtual reality, as a superior exercise intervention, is effective in improving the balance of children with cerebral palsy.

Paying attention to the social responsibility of the company has become an inseparable part of the business, because all companies are related to their social environment whether they want it or not, and their long-term social survival depends on paying attention to social issues. Therefore, in addition to their economic responsibility, companies are also responsible for social responsibility in the form of paying taxes. Financial helplessness and bankruptcy of companies leads to waste of resources and failure to intercept investment opportunities.The internal function of social responsibility and institutional ownership can lead to the improvement of the company's position, increase in efficiency, profitability, value and long-term survival of companies. By disclosing social responsibility, companies can obtain material and non-material support from institutional investors. Descriptive statistics of the tested variables, which includes some centrality and dispersion indicators, which shows the observation year between 1392 and 1399 for a sample of 575 companies. The results of the research show that the relationship between corporate social responsibility and financial distress is negative and significant, there is a significant relationship between institutional shareholders on the board of directors (institutional ownership) and the financial distress of companies listed on the Tehran Stock Exchange. And between the amount of institutional shareholders who own companies (managerial ownership) has a significant relationship with the financial distress of companies admitted to the Tehran Stock Exchange.

The present study was to prepare and validate character strength training package and effectiveness on assertiveness skills of adolescents.

This was a quasi-experimental study with a pretest-posttest design with a control group. First, the training package was prepared and validated. Once the goals were identified, appropriate content was prepared for each strength. Finally, after applying the opinion of experts, a training package was developed. Content validity index (CVI) and content validity ratio (CVR) were high for all objectives in the training protocol. Character Strength training package in the form of 12 sessions compiled 70 minutes. The statistical population included female high school students who were studying in schools in Tehran in the academic year 2020-2021. Students were selected by available sampling method and answered the assertiveness questionnaire. Among them, 30 students whose expression was a deviation below average were randomly assigned to the experimental group (n = 15) and the control group (n = 15). The Gambrill and Ritchie (1975) Expression Questionnaire was used to assess assertiveness.

The results of univariate analysis of covariance (ANCOVA) showed that the mean post-test scores in the experimental group were higher than the control group.

Based our findings, it can be concluded that the prepared character strength training package had an effective role in increasing adolescents' assertiveness

Semantics Scientific study is a meaning that is one of the sub-branches of linguistics and includes cognitive, historical, descriptive and .... approaches. The descriptive approach of this science, which we mean, includes companionship and substitution. Our attention in the present research is on the companionship part of this science, and we try to deal with the relationship between the word Zakat and its derivatives with its companions through the companionship relationship. In this regard, let us understand the issue of Zakat, which is one of the branches of religion, due to the great emphasis of God among all our commands. What adds to the importance of this research is that the word Zakat with its derivatives is mentioned 59 times in the Holy Qur'an, and certainly in a book like the Qur'an, where everything is stated in its place, the repetition of this word is not without reason. Findings of the study indicate that the word Zakat is associated with words such as Salah, Wali, Obedience to God and Obedience to the Messenger, Tab, Amen, Don al-Khuf and Al-Hazn, Barr, Muttaqoon, Jahed and Hanan and its derivatives with permission, Az Al-Basr and Hafiz Al-Faraj. In the meantime, the word "Salah" has the highest frequency of associating with Zakat, and the reason for this is that God intends to convey to Muslims the status and value of these two branches of religion, as if he considers the condition for accepting the rest of the actions of Muslims after these two acts.

Saliva is one of the most important body fluids. The lack of this fluid has many outcomes for the patient. The aim of the present study was to detect objective and subjective dry mouth in individuals with no oro-dental complications in Shiraz, Iran and compare these factors to depression level, medication intake and level of education. 

In the present descriptive cross-sectional study conducted at Shiraz Dental School in 2018, 450 samples were selected from the Patients' companions referred to Shiraz Dental School over 18 years. In the present study, the Fox questionnaire was used to mentally assess dry mouth (zerostomia) and the Zong self-assessment scale was used to assess depression. Spitting method was used to evaluate the amount of stimulated and unstimulated saliva (objective dry mouth or hyposalivation). When saliva was less than 0.1 g/min, objective dry mouth was stimulated and when saliva was less than 0.7g/min, objective dry mouth was considered non-irritating. Data were analyzed using SPSS software and chi-square test.

In the present study, 399 patients (118 males, 280 females) were studied. Dry mouth (zerostomia) was found in 46% of the population. However, 18.5% had non-stimulated objective dry mouth and 12.3% had objectively stimulated dry mouth. Patients aged 30 to 45 years suffered more from mental and objective dry mouth compared to other age groups (p=0.048 and p=0.032). Depression, use of antihypertensive and antidiabetic drugs and low level of education were significantly associated with objective dry mouth (p<0.01, p<0.01 and p=0.038).

Mental dry mouth can occur apart from objective dry mouth. Correspondingly, dry mouth as an objective and mental symptom can be seen not only in the elderly but similarly in the young peoples. Physicians and dentists must deal with the factors that cause this complication, such as; depression, medications, and education levels as a disabling and destructive condition that affects all age groups.

In this study, the effectiveness of cognitive-behavioral therapy with Islamic approach on social anxiety of the first and second period high school female students in the 2019-2020 school year was investigated.

The research method was a mixed one (qualitative and quantitative). The first part of the research (preparation of a cognitive-behavioral package with an Islamic approach) was performed qualitatively using the analysis of religious propositions. To investigate the validity of the package, some religious experts were asked to give comments on rightness of traditional readings by scholars and the accordance of the suggested techniques in the Islamic cognitive-behavioral package with the objectives of each session. The quantitative part was of quasi-experimental type consisted of two cognitive-behavioral groups with an Islamic approach and a control group. Among those who referred to the Education Counseling center in Kerman city with a complaint of social anxiety, 36 persons were studied by available sampling method, and 18 subjects were randomly assigned to each group. The data collection tool was the social panic questionnaire of Connor et al (2000). Data analysis was performed using descriptive statistics, univariate analysis of covariance and SPSS-22 software.

The findings showed that cognitive-behavioral therapy with Islamic approach significantly reduces students’ social anxiety (P<0/001).

Based on this study, it can be suggested that this treatment be used to reduce students’ social anxiety.

Organic coatings are the single most widely applied materials to protect metallic substrates against corrosion. Therefore, coating researchers need to understand how a coating can guarantee protective performance during service life. This study it is tried to find how adhesion durability can affect the protective performance of a coating. An epoxy resin (Araldite GY 783) was cured with a mixture of two types of hardeners (a polyether polyamine and a cycloaliphatic polyamine) in four different mixing ratios (i.e. 20–80, 50–50, 70–30, 90–10) to achieve various adhesion behaviors, water permeability, and viscoelastic properties. Samples were exposed to humidity in the testing chamber for 300 days and adhesion was measured at wet and dry conditions over time. After drying, adhesion loss and recovery were evaluated by a pull-off test. The electrochemical behavior of coatings was studied by electrochemical impedance spectroscopy (EIS). A series of impedance spectra of coatings during exposure to humidity were recorded and their protective properties were compared. The results showed a correlation between protective properties and viscoelastic behavior of coatings. It was found that a sample with a cycloaliphatic hardener has a higher elastic modulus (1275 MPa) and a sample with a polyether polyamine hardener has a lower elastic modulus (465 MPa). Additionally, it was found that a sample with excellent initial protective properties (|Z| =1010 Ω cm2), higher elastic modulus, and low initial water permeability (0.308 g/m2hr) may quickly fail because of the adhesion failure after wet cycles.

Holy Quran, stylistics, phonetic level, compound level, rhetorical level Stylistics is a science that, by examining descriptions and analyzes, reaches the literary aspects of a text and conveys the meanings and concepts of a literary text clearly to the reader. The Holy Quran, which is a divine miracle, has come to the attention of stylists as a literary text, especially in recent years. This article seeks to study Surah An-Najm in three levels of phonetics, composition, and rhetoric using a descriptive-analytical method and using the knowledge of stylistics in order to understand the literary and semantic aspects of the Surah. In Surah An-Najm, at the phonetic level, by using rhyme, it causes the surah to be melodic and attracts the audience to this surah. At the compound level, he draws a line at the pagans' beliefs and beliefs by using phrases such as offerings and delays. At the rhetorical level, he uses the method of limiting God's ownership and that everything is by God's permission.

Investigation of rheological parameters on the protective performance of an epoxy coating through wet and dry cycles has been studied using creep-recovery modeling. For this purpose, an epoxy resin was cured with four types of hardeners (Polyamine-based, Polyamidoamine-based, Polyether polyamine-based, and Cycloaliphatic Polyamine-based hardener) to achieve various adhesion behaviors and viscoelastic properties. The storage modulus, viscoelastic creep-recovery, permeability, electrochemical parameters, and glass transition temperature were determined. Samples were exposed to humidity chamber and adhesion was measured at wet and dry conditions over time. After drying, adhesion loss and recovery were evaluated by the pull-off test. The electrochemical behavior of coatings was studied by electrochemical impedance spectroscopy (EIS). It was found that the higher the elastic module, the more the adhesion loss. Recovery of adhesion after wet and dry cycles correlated with the reversible element of creep and recovery data. After that, creep recovery data were modeled and for the first time, two rheological parameters (viscose ratio and the elastic ratio of the viscoelastic behavior) were defined for predicting adhesion durability. A coating with a higher viscose property in creep recovery behavior shows week adhesion recovery . It may referred to irreversible strain in a coating that cannot be recovered after the elimination of stress. Additionally, it was found that a sample with excellent initial protective properties, higher elastic modulus, and low initial water permeability may quickly fail because of the adhesion failure after wet cycles.

Anxiety and aggression, as the indicators of non–adjustment, can present adverse effects, such as impaired functioning and health conditions. Social anxiety disorder is a pervasive condition in which an individual experiences severe fear in the company of others or when functioning in front of them. There exists a high prevalence and destructive consequences of such disorders concerning social functioning, education, and interpersonal relationships. Extensive investment has been performed in therapeutic interventions. One of these interventions that have received the most scientific support is Mindfulness–Based Cognitive Therapy (MBCT). Recently, due to the high prevalence of social anxiety disorders and aggression and the consequences of these conditions on the quality of social life of patients, psychological therapies are expanding in this area. Accordingly, this study aimed to evaluate the effects of MBCT on social anxiety and aggression in first– and second–grade female students.

This was a quasi–experimental study with a pretest–posttest and a control group design. The study population included all first– and second–grade high–school females in Kerman City, Iran, in the academic year of 2019–2020 who were referred to the counseling center of the General Directorate of Education (Department of Education) due to psychological problems. The sample size was selected based on the research type. Accordingly, 36 individuals were selected as the research sample by random sampling method and assigned to the experimental and control groups (n=18/group). For gathering data in pretest and posttest phases, we used the Social Phobia Inventory (Connor et al., 2000) and the Aggression Questionnaire (Bass & Perry, 1992). The experimental group received 8 two–hour sessions (twice a week) of MBCT as per Kocovski et al.’s package (2015). Descriptive statistics, such as mean and standard deviation and inferential statistics, including Analysis of Covariance (ANCOVA) were used to analyze the obtained data in SPSS. The significance level of the tests was considered 0.05.  

The ANCOVA results indicated that after removing the pretest effects, there was a significant difference in social anxiety and aggression between the control and experimental groups in the posttest step (p<0.001). The relevant effect size was measured as 0.38 and 0.14 for social anxiety and aggression, respectively.

According to the research results, MBCT reduced social anxiety and aggression in the examined students. Thus, psychologists and counselors can use this technique to reduce students' psychological problems.

Cerebral Palsy (CP) is a disorder of movement and posture with extensive variety and classifications. Spastic hemiplegia is the most prevalent CP type. The motor limitations appear in combination with sensory and cognitive alterations that result in great difficulties for children with CP to manipulate objects, communicate, and interact with their environment, subsequently limiting their mobility. Eye–hand coordination is the skill in which visual information from the eyes and motor data from the hands are efficiently applied to work together as an essential component of self–help activities, play, perception, and school work. Therefore, problems with eye-hand coordination make it difficult for children to experience search tasks in their daily lives, such as playing and school activities. Eye–hand coordination is critical in functional performance and should be carefully considered by coaches and occupational therapists. Thus, the current research aimed to investigate the effects of exercise interventions on eye-hand coordination in children with spastic hemiplegic CP.

This was a quasi–experimental study with a pretest-posttest, a control group, and a single–blinded design. We classified three experimental groups of physical activity, virtual reality, physiotherapy, and a control group. Twenty children with spastic hemiplegic CP from Golha Special School in Shiraz City, Iran, in 2019 were selected by convenience sampling method. The inclusion criteria of the study were as follows: girls and boys with spastic hemiplegic CP (6–12–year–olds); specified as level 1–3 on the Gross Motor Function Classification System (GMFCS) (according to relevant occupational therapist & their medical records); no visual or auditory impairment; no previous experience working with Xbox; no use of anticonvulsant drugs; no orthopedic surgery; no lower limb Botox injections for 6 months prior to intervention, or the presence of other disorders, such as autism, asthma, etc. (according to their parents & their medical records). Subjects’ inability to follow the intervention program and instructions, and having more than three absences in the training sessions were the exclusion criteria of the study. Children were randomly divided into 4 groups of physical activity (a set of aerobic exercises, balance skills, coordination exercises, walking distance, ball skills, copying shapes, & painting were performed under the supervision of an occupational therapist & the relevant expert), physiotherapy (joint movement exercises, muscle extensions, muscle strength exercises, torso stability exercises, tracking, & grasping objects held by a physiotherapist, by stretching the arms in different directions in a sitting position), virtual reality (offering Xbox 360 Kinect games, including jumping, weight transfer, stepping from one side to the other, using the arms and legs to prevent bloating, or using arms and legs coordinated movements to cover the cavities created by the blows of the fish in the body of the aquarium), and the control group (exempt from intervention) (n=5/group). In addition, all study participants continued their treatment and physiotherapy programs for two weekly sessions during the research process. The experimental groups received interventions for 8 weeks, 3 sessions per week, and 30 minutes per session. The Visual Motor Integration Test (Beery, 1989) was used to assess eye–hand coordination. Repeated–measures Analysis of Variance (ANOVA) was used to explore the impact of interventions in the different stages of the test. Besides, the Bonferroni post–hoc test was used to determine the sustainability of the effect of interventions, and the level of significance was set at 0.05.

The obtained results indicated a significant difference between the effects of interventions on eye-hand coordination in different groups, including physical activity, physiotherapy, and virtual reality, (p<0.001). To measure the effectiveness of the interventions, according to the pretest-posttest stages, the relevant results indicated a significant effect of the interventions in all three groups of virtual reality (p<0.001), physical activity (p<0.001), and physiotherapy (p=0.008). To measure the duration of interventions according to the posttest and follow–up stages, due to the negative coefficient of difference, the duration of intervention in physical activity (p=0.010) and physiotherapy (p=0.044) was low, and the duration of virtual reality intervention, compared to the other two groups was noteworthy (p=0.108).

According to the present study results, it can be concluded that, compared to other interventions, designing exercise programs via virtual reality environment can play a role in improving the eye–hand coordination of children with CP.

Agriculture is considered an important sector in the world economy. However, this section is always associated with risk, implying the need for more attention to risk management. In this regard, it is important to consider the role of extension training programs and how farmers react to risk. The main purpose of this research was to present a risk management model with focusing on the role of extension training programs among rain-fed wheat producer in Kermanshah province (N=83442). The sample size was determined based on krejcie and Morgan table (n=383). This research has been done through a survey method and multistage sampling method was used to select 383 farmers. Questionnaire was main research instrument. The content validity of the questionnaire was confirmed by panel of experts and the reliability of different parts was approved with Cronbach,s alpha test (0.73 ≤ ɑ ≤ 0.94). The data were analyzed using SPSS and Smart PLS software. Results showed that the positive significant relationship between the awareness of risk sources and extension training programs. Also, the proposed model can explain 50% of changes in risk management. The results of this research provide useful insights for researchers, extension agents and farmers to develop appropriate risk management strategies by expanding the level of collaboration.

Considering the important role of women along men in consuming a food product, the aim of the current study was studying women's and men's insight about barriers and solutions to increase the consumption of livestock-originated organic products in Kermanshah city.

Using the Delphi method, 13 barriers and 15 solutions were extracted from answers given by animal husbandry specialists and were used for preparing the questionnaire. A total of 395 men and women in Kermanshah answered the questions and data were analyzed by Friedman’s test using SPSS 15 software.

The least frequently used sources of information for men and women were television and the most frequent was written media (books, newspapers, magazines, and the Internet). In both groups, the most important challenge facing the development of organic animal food consumption was the high cost of these products and the least important challenge was their inappropriate form. But men's and women's views on ways to develop organic products consumption were not the same. For men, the most and least important factors in using organic livestock products were the creation of confidence in the organicity of these products and their internal and external marketing, respectively. On the other hand, women believed that price adjustment was the most important strategy and brand and logo development was the least important in promoting the consumption of such products.

From the consumers' point of view, considering the economic, infrastructural and cultural indices can eliminate the barriers of consumption of organic products.

Electrodeposition of nano titania from aqueous dispersion has been studied. Properties of The electrodeposited layer are related to nanoparticle type, morphology, structure and process characteristics. These properties are directly affected by preparation method and electrodeposition parameters such as current density, substrate type, pH, ionic concentration, size, type of nanoparticles, electrolyte mixing, etc. Characteristics of nano titania could affect the conversion efficiency of DSSC (Dye Sensitized Solar Cell) significantly. Electrodeposition is a good candidate for applying nano titania as a semi-conductor. In this study the effect of electrodeposition current density on the adsorption of different types of dyes on electrodeposited nano titania in a DSSC has been studied. N455-PF6 showed more dye adsorption on the electrodeposited nano titania. The increasing current density, the raising nano titania thickness and deposition yield. Comparing three types of dyes (P1, N455-PF6, N719) showed that N455-PF6 represented a linear and reproducible absorption by increasing current density.
