Purpose: The school principals’ competence plays an important role in improving the education system. As a result, this study aimed to investigate and present the competency model of high school principals. Methodology: The current research was applied in terms of purpose and mixed (qualitative and quantitative) in terms of implementation. In the qualitative part, the research population was the educational management experts of Guilan province in the academic year of 2021-22, and according to the principle of theoretical saturation, 15 of them were selected as a sample using targeted and snowball sampling methods. In the quantitative part, the research population was the principals of the second year high school in Guilan province in the academic year 2021-22, and according to the table of Krejcie and Morgan, 127 of them were selected as a sample by stratified random sampling method. The research instrument was a semi-structured interview in the qualitative part and a researcher-made questionnaire in the quantitative part, whose psychometric indicators were checked and confirmed. The data of the qualitative part were analyzed by open, axial and selective coding method in Maxqda software, and the data of the quantitative part were analyzed by exploratory factor analysis method in Amos software. Findings: The results of the qualitative section showed that 137 indicators, 17 components and 5 dimensions were identified for the competence of high school principals; so as to include the dimensions of belief (with the components of cognition, belief, value and behavior), rational (with the components of discretion power, future studies and effective decision-making), personal (with the components of creating a positive environment, needs assessment, mental health and the flourishing of talents), managerial (with the components of human/general skills, perceptual/maturity skills and specialized/leadership skills) and educational (with the components of teaching and learning process, educational supervision and guidance, and educational evaluation). Also, the results of the quantitative section showed that the factor load and the average variance extracted of the dimensions and components were higher than 0.50 and their content validity and reliability ratio with Cronbach’s alpha method was higher than 0.80. In addition, the Competency model of high school principals had a good fit and each of the dimensions had a significant effect on the corresponding components and each of the components had a significant effect on the corresponding indicators (P<0.05). Conclusion: According to the competency model of high school principals, planning to improve and promote the competence of school principals through the identified dimensions, components and indicators seems necessary.

Purpose: The current research was conducted with the aim of designing the national identity curriculum model for the second elementary school. Methodology: According to the nature and scope of the research, various qualitative methods were used to achieve the research objectives, which include: a) grounded theory, to design the national identity curriculum model in the elementary school; b) Thematic analysis method to determine the characteristics of elements of national identity in primary school textbooks to achieve the curriculum model of national identity. In part A, the community was studied by experts in the field of national identity, including experts in social sciences and educational sciences and upper education documents. The method of gathering information from experts was through semi-structured interviews with 36 teachers and experts. Also, the interviews were conducted based on the grounded theory in three stages of open, central, and selective coding, and the obtained concepts were classified into categories and subcategories. Findings: National identity curriculum model was presented in two dimensions of why and the necessity of national identity curriculum and how national identity curriculum in the form of a conceptual model, including the necessity and need (needs assessment), goals (general goal and partial goals), content (principles of content organization, content selection), teaching methods, learning, teacher's role, and evaluation methods. Conclusion: Among the features of this model, we can refer to being native, attention to individual, social, ethnic and national characteristics, being scientific, simplicity, originality, educational outlook and active approach in teaching and learning.

Women have always been of cultural relevance as one of the most important elements of the society. The central role of women in cultural development has caused significant increase in the attention to these areas in recent years. The main aim of this research has been to interpret the women's status in cultural development and improvement. For this purpose, first based on theoretical principles and the literature available in this regard, the initial conceptual model was prepared. Then, based on the opinions of the statistical population of the research, as experts specialized in culture, interpretation of the indices of this model has been done. The sampling method in this research has been cluster, with the sample size determined as 384 using Morgan table. In this research, for measuring the research indices, questionnaire has been used. The reliability of this questionnaire was confirmed through Cronbach alpha coefficient, and its validity via construct validity method. The results of this research led to identification of the major indicators and components affecting the women's status in cultural development and improvement.

The athlete's skills and psychological state often influence success in sports performance. The current study aims to explain the performance in paintball competitions based on cognitive resilience and cognitive regulation of emotion. The study participants included all paintball players participating in national paintball competitions (the year 2022), including 17 teams of 7 players, a total of 116 people. In order to investigate the psychological components affecting the athletes' performance, Conner-Davidson Resilience Scale (CD-RISC) and Cognitive Emotion Regulation Questionnaire (CERQ) were used. After completing these questionnaires, IBM SPSS Statistics version 26 was used to analyze the data. Pearson's correlation coefficient and stepwise regression were used to analyze the data. The results showed a significant relationship between resilience scores, the overall score of cognitive emotion regulation, and the scores of 9 emotion regulation strategies with the players' performance in the paintball competition (P≤0.05). Players who achieved better results in tournaments, scored higher on the resilience factor. Also, players who achieved better results in matches had higher scores on emotion regulation strategies like self-blame, positive refocusing, refocus on planning, positive reappraisal, and putting into perspective, and lower scores on the acceptance, rumination, catastrophizing and other-blame strategies. This study showed that cognitive resilience and emotion regulation could be used as predictors of success and winning positions in paintball competitions.

The aim of the present research was to evaluate the effectiveness of a therapy package for weight control based on Acceptance and Commitment with the Matrix Approach and Transcranial Direct Current Stimulation (tDCS) on Food Craving and Physical Activity in overweight individuals. The research Design was a quasi- experimental with pretest and posttest and An Active Control group. For this purpose, 40 persons were selected via availability sampling and in regard to include and exclude criteria. The instrument of the study were Baecke's Physical Activity Questionnaire (1982) and Food Craving Questionnaire-Trait of CepedaBenito (2000, FCQ-T). The experimental group received the intervention package in 12 online group sessions of 2-hour weekly sessions and 8 individual sessions of tDCS AR/CL stimulation (2Ma for 20 minutes) and the control group received only 8 individual tDCS sessions of AR/CL stimulation (2Ma for 20 minutes). The results of between- within group mixed analysis of variance showed that the combined intervention package of weight control based on Acceptance and Commitment with the Matrix Approach and Transcranial Direct Current Stimulation (tDCS) had a significant effect on physical activity and cravings of overweight people in comparison with tDCS alone. According to the results, it can be concluded that the therapeutic package of the present study can be a good option to increase Physical Activity and reduce Food Craving.
