This study examines the impact of cognitive and physical interventions on the quality of life and stress among middle-aged retired athletes. Utilizing a narrative and descriptive analysis method, articles published between 2020 and 2024 were reviewed. The findings indicate that physical interventions such as aerobic, resistance, and flexibility exercises lead to improved physical health, increased muscle strength, and enhanced immune function, thereby improving quality of life and reducing stress. Conversely, cognitive interventions like mindfulness exercises and cognitive-behavioral therapy positively affect mental health and stress reduction by altering negative thought patterns and enhancing coping skills. The combination of these interventions creates synergistic effects that contribute to overall health improvement and increased longevity. However, limitations such as the need for long-term commitment, access to resources, and professional expertise may affect the implementation of these interventions. Therefore, it is recommended to design combined and personalized intervention programs that consider individual needs and conditions to improve quality of life, reduce stress, and prevent diseases in middle-aged retired athletes.

 the aim of the present study was to investigate the effect of cumin intake following partial sleep deprivation (PSD) on the oxidation of carbohydrates and fats and some cardiorespiratory indices in student-athletes.

The present study was quasi-experimental and the research design was cross-sectional. The statistical population included all female student-athletes of Imam Khomeini International university (Age: 18-25 years), of whom 8 students were chosen based on convenience sampling method (Age: 20.01± 53 0.53; height 163.50± 6.57 cm;, weight 56.54± 2 2.54 kg; body mass index 21.19 ± 1.85 kg / m2; maximum oxygen consumption 87 58.30±5.5 kg / min and heart rate 93.63 ±5.15 beats per minute). The main group consisted of 8 subjects who were initially tested as a control group; they were then tested again as placebo and supplement groups after a seven-day wash out period, respectively. PSD was performed for 4 hours the night before the test. Exhaustion was measured and recorded by Bruce treadmill test; cardiorespiratory parameters, carbohydrate and fat oxidation were analyzed by gas analyzer.

The results suggested that carbohydrate oxidation increased at the time of maximum oxygen consumption (Vo2max) in the cumin supplement group (p≤0.05). Carbohydrate oxidation and respiratory exchange ratio also increased at the time of anaerobic threshold and Vo2max in cumin supplement group (p≤0.05).

In summary, it can be said that taking cumin pills improves the performance of sleep deprived athletes.

The purpose of this study was to analyze destructive leadership and its consequences in schools in Tehran province. The present study is qualitative research that was conducted using the interpretive phenomenology strategy and Colaizzi's analysis method. In line with this goal, the perceived experiences of teachers regarding the destructive behaviors of school principals and their consequences were explored. The research field was primary and secondary schools in Tehran province. Fourteen interviews were conducted using purposeful and snowball sampling methods through semi-structured interviews with teachers and school assistants. The duration of the interviews was between 40 and 60 minutes. After analyzing the data, 35 components related to destructive leadership behaviors were discovered, which were classified into 8 main themes of destructive behaviors: dominance and mastery, narcissism, unfavorable political behavior, offensive behavior, lack of empathy, unfair behavior, micromanagement, resistance to change, and lack of responsibility. Also, 25 components related to the consequences of destructive leadership were extracted and categorized into 8 main themes. Such an atmosphere leads to a decrease in job motivation, an increase in interpersonal tensions, a decrease in cooperation and interaction, a lack of professional development, a decrease in interpersonal trust, a lack of completion of the teaching staff, a decrease in physical and mental health, and the poisoning of the school environment. The results of the research confirm the occurrence of destructive behavior of managers in Iranian schools. By paying attention to teachers' voices, this research tries to increase awareness about destructive leadership in the educational environment and to consider the need to improve leadership mechanisms in educational organizations.

The gap between theory and practice has always been a subject of debate among theorists and practitioners. Practitioners frequently critique the limited applicability of theory in real-world organizational settings, while researchers express concern over the perceived lack of theoretical grounding in Human Resource Development (HRD) practice. In response to this critical issue, actionable knowledge development has emerged as a key area of investigation. The present study aims to address this gap by proposing a model for the development of actionable knowledge among HRD practitioners. Employing a qualitative research approach, the research data were collected through semi-structured interviews with a sample of 24 HRD practitioners from Iran’s administrative system. To this end, thematic coding strategies (open and axial) were used to analyze the interview data. The findings revealed a cyclical model of actionable knowledge development, characterized by six key stages. These stages revolve around two axes: "knowing" and "doing." The "knowing" axis encompasses three stages: Receiving, adapting, and searching for knowledge. The "doing" axis, conversely, comprises three stages: Legitimizing, reconfiguring, and rendering knowledge into practice. By fostering attention to this cyclical model, individual and organizational development can be facilitated. Furthermore, this model has the potential to bridge the gap between the social system of science and the social system of practice, ultimately promoting the formation and application of practical knowledge for HRD practitioners to effectively address everyday challenges.

The implementation of the Fundamental Reform Document of Education (FRDE) has been one of the significant issues of the education system in our country in the last decade. FRDE, similar to all educational policies and reforms, is affected by the adaption process and is not necessarily implemented according to policymakers’ intentions.The aims of this study is to understand and explain the meaning made by school principals of their role during the implementation of FRDE and investigates how to implement the transformation document. This qualitative study was conducted using the phenomenology method and based on the cognitive framework of sensemaking. Data was gathered through semi-structured and in-depth interviews with 8 public high school principals in four district 3, 6, 7, and 13 of Tehran. Participants were selected using purposive sampling. Data analysis method of Miles et al. (2014) led to the formation of three main theme categories “ambiguty”, “documentary”, and “individual and situational factors”. Finding illuminates, the ambiguity of FRDE’s text and how it is transitioning to practice. The requirement to act in such a situation leads principals to make another sense of their role and they perceive themselves as documenters. In light of the findings, forming this meaning was affected by individual factors including same-old and to-no-avail attempts, as well as situational factors including the extent of applying, rules and regulations, and value position. According to the findings, despite the efforts made to implement the FRDE in schools, the main purpose of the implementation of it has not been achieved. The attention of policymakers to the factors that shape sensemaking can help in designing educational policies and more effective implementation.

Most of the administrators of the universities are faculty members and they have not received the necessary training and have not been evaluated in an organized manner. Considering the importance of paying attention to competency in the selection of efficient and effective administrators and considering the critical role of universities in the society, the aim of the current research is to development and validation a general competencies model for public universities’ administrators in Tehran. A qualitative method was used in this research; Thematic analysis method was used to design the competency model and Delphi technique was used to validation the designed model. The sample was the administrators of the public universities in Tehran, and semi-structured interviews were conducted with 27 of them. After the qualitative analysis of the implemented interviews, the primary model was extracted using thematic analysis. Delphi technique was used to validating the extracted model, and the final competency model, which consists of 12 competencies, was formulated with the opinion of experts. Competencies were classified into three general categories: managerial competencies, interpersonal competencies, and personal characteristics. Managerial competencies include leadership, organizational awareness, problem solving, planning and organizing, and supervision and control; Interpersonal competencies include communication skills, networking and negotiation and persuasion, and personal characteristics include result orientation, continuous learning, resilience and professionalism. Considering the key role of managers in achieving the goals of universities, it is recommended to use the competency model extracted in this research for the appointment and promotion of administrators.

In recent decades, there has been significant emphasis on educational leadership and the performance of school principals in educational policies. The aim of this research is to explore and examine upper-level documents and conducted studies in order to clarify the current state of educational leadership and the transition towards it.

The current research is practical in terms of purpose and employs qualitative data collection and documentary analysis. It utilizes an inference-based approach through conceptual analysis and re-conceptualization. This method is a type of systematic review in which the researchers use it as a tool for categorizing a set of features related to a phenomenon and explaining them, instead of relying on a set of statistical rules. The study population consists of all relevant domestic research on educational leadership and upper-level documents of the educational system in the Islamic Republic of Iran, which were selected using purposive sampling of research and relevant documents.

The findings of the domestic research related to the topic of educational leadership at the school level indicate the identification of 29 features, which were categorized into four dimensions: "organizational management and improvement," "individual progress and educational development," "leadership patterns and models," and "leadership description."

Based on the analysis of the upper-level documents, it can be stated that except for the Fundamental Transformation Document (2011), in other documents, the topic of educational leadership has been implicitly and indirectly addressed under themes such as "school-centered management," "participatory management," "school-centeredness," "curriculum guidance," "facilitation," and "guidance."

In recent years, mixed methods research has gained popularity in doctoral theses, particularly in educational administration and higher education. This study delved into the approach, design, and research methodologies employed in these theses. By thoroughly analyzing the abstracts and third chapters of 85 doctoral theses, the research aimed to elucidate the prevailing trends in mixed methods research within the realm of education. The findings of this study reveal that a significant majority, 73%, of the examined doctoral theses aimed at developing patterns or models.

The succession planning is an effective strategic approach to maintain and develop human resources within organizations. Although succession is an effective strategy to focus on creating a regular structure for organizations, many companies lack regular succession planning, so that people with the necessary skills and expertise cannot be placed in specific positions. Based on this, the aim of this article is to find the effective components on succession with the approach of attracting and developing academic talents in engineering companies. In this research, a qualitative meta- synthesis method has been used. After conducting a keyword search in reputable national and international databases from 1997 to 2023, a total of 2,181 studies are identified, and 91 studies are selected for the purpose of analysis and information extraction. After conducting analysis, succession planning with a focus on attracting and developing university talents at engineering companies is categorized into 5 dimensions Including: creating commitment, determining policy, attracting and developing academic talent, leadership improvement program and program evaluation and 11factors and 30 sub-factors. Based on the finding, it is worthwhile mentioning that the components of succession planning are determined with a focus on attracting and developing university talents, due to which this research can assist companies to formulate and implement succession planning programs having employed university talents.

 Spinal cord injury is a serious injury that leads to permanent or transient severe spinal cord dysfunction including sensory, motor, and sphincter deficits. In terms of etiology, it is divided into traumatic or non-traumatic causes. Traumatic spinal cord injury, most commonly caused by motor vehicle accidents, falls, sports accidents, and violence, has severe long-term effects on patient outcomes and can lead to permanent disability and dependency. In recent decades, due to medical advances, more patients with spinal cord injuries survive and live longer. Therefore, in addition to the physical and neurological prognosis, research focuses on the general well-being and quality of life of these patients. In addition, satisfaction with quality of life is the main goal of primary treatment and rehabilitation. This study was conducted to investigate the long-term quality of life of patients with traumatic cervical spinal cord injury in Haftome-Tir Hospital, Tehran.

 This study was carried out cross-sectionally and all patients with traumatic cervical spinal cord injury who underwent surgery from September 2018 to September 2021 were followed up. Required demographic, clinical, and surgical information including age, gender, trauma mechanism, level of involvement, clinical examination status, type of surgery, duration of hospitalization, and other required variables were collected and registered from patient records and picture archiving and communication system (PACS). Short-term outcome including hospital mortality was collected through patient records. Then, the long-term outcome of the patients, which included health-related QoL assessment was obtained using the Short Form Health Survey- 12 items (SF-12) tool in two areas of physical health (Physical Component Summary (PCS)) and mental health (Mental Component Summary (MCS)) through a telephone call and outpatient visits of patients in the clinic. SF-12 is a reliable instrument and one of the most commonly used tools to assess the quality of life of patients with spinal cord injury and other debilitating diseases. Although the SF-36 is the gold standard for this topic, due to its length and complex clinical use, the SF-12 has replaced it in some studies and is becoming more popular.
The inclusion criteria for the study included all patients who underwent surgery with traumatic cervical spinal cord injury. Also, the criteria for exclusion from the study included: the presence of an underlying neurological disease involving the spinal cord, a history of underlying neurological disease involving the spinal cord, hemorrhagic shock and unstable patients due to traumatic injury of intra-abdominal and thoracic organs, the need for emergency spine surgery, non-traumatic spinal cord injury, unrelated death during the study and follow-up, history of spine surgery for other reasons before the trauma, and lack of consent to participate in the study. Data analysis was done by SPSS statistical software version 25. For qualitative variables, frequency and percentage of frequency, and for quantitative variables, mean and standard deviation were calculated. Independent t-tests, ANOVA (analysis of variance), post hoc tests, chi-square, and one-parameter non-tests were also used for analysis. A significance level of 0.05 was considered. This research has been approved by the Ethics Committee of the Iran University of Medical Sciences with the ethical code of IR.IUMS.FMD.REC.1401.587. The principles of the Helsinki Convention were considered. All patient information is confidential and the results have been mentioned anonymously.

 After taking into account the exclusion cases, 75 patients with traumatic cervical spinal cord injury were analyzed during the study period. The average age of the patients was 44.95±15.58 years with a minimum age of 17 and a maximum of 79 years. Sixty patients (80%) were male and fifteen patients (20%) were female. Motor Vehicle Accidents (44 patients-58.7%) and then falling from a height (16 patients-21.3%) were the most common causes of injury in the studied patients. 44 patients (58.7%) had complete spinal cord injury, 30 patients (40%) had incomplete spinal cord injury, and 1 patient was diagnosed with Spinal Cord Injury Without Radiographic Abnormality (SCIWORA). Among the patients with incomplete spinal cord injury, 26 patients (86.7%) had central cord syndrome and 4 patients (13.3%) had Brown-Sequard syndrome. The most common cause of spinal cord injury was fracture and dislocation of the cervical spine (43 patients-57.3%). The most common type of fracture was Burst type, which was observed in 24 patients (57.1%).
The most common involved level was C5, which was observed in 14 patients (33.3%). In patients with cervical canal stenosis who suffered spinal cord injury following trauma, the number of cervical vertebrae involved was 3 levels in 3 patients (15.8%) and 4 levels in 8 patients (42.1%). In patients with cervical discopathy who suffered spinal cord injury following trauma, the most common level involved was C3/4 in 5 patients (55.6%). In 38.8% of patients (26 patients), the anterior surgical approach, in 34 patients (50.7%), the posterior surgical approach, and in 7 cases (10.5%) combined anterior and posterior surgical approach was performed. The average interval between the occurrence of spinal cord injury and surgery was 3.78±2.93 days. The average length of hospitalization in the patients was 22.83±21.76 days. 55 patients (73.3%) were discharged from the hospital and 20 patients (26.7%) died during hospitalization. The follow-up period of the patients was between 18 and 60 months and the average was 43.83±14.43 months.
Also, 9 patients (12%) died after being discharged from the hospital during the rehabilitation period.
The final result of the patients. The average quality of life score of patients for physical quality of life (SF-12 PCS) was 34.27±9.73 and for mental quality of life (SF-12 MCS) was 46.65±10.27. Moreover, 66.7% of patients had SF-12PCS below 50, which indicated a lower quality of life than normal in society. Also, 42.5% of patients had a score of SF-12MCS below 42, which indicated clinical depression. The outcome of SF12PCS had a significant statistical association with the following: it was better in Brown-Square syndrome (46.35) than in the central cord syndrome (31.14) (P=0.004) and was also better in stenosis with or less than three levels (49.55) than more than three levels stenosis (33.72) (P=0.04).
The outcome of SF12MCS had a significant statistical association with the following variable: it was better in Brown-Squad syndrome (57.18) than in the central cord syndrome (44.19) (P=0.02).
It should be noted that the age of patients and the time of surgery after the injury did not have a significant statistical association on the final outcome (SF-12PCS and SF-12MCS) (P>0.05).

 Although assessment of neurological and physical recovery in patients with spinal cord injury is important, it should not replace assessment of QoL. This study and other studies that evaluate the QoL of SCI patients seem to be an introduction to further research to evaluate the QoL and the factors involved in it.        

The global spread of COVID-19 has disrupted many aspects of our lives. Education systems around the world have changed dramatically. Several countries have encouraged schools to switch to e-learning, and as a result, parents' involvement in their children's education has changed. This research was conducted with the aim of validating the antecedents, effective factors and consequences of the participation of parents of primary school students in online education.

The statistical population of the present study was all parents, teachers and principals of elementary schools in the 1st and 19th education districts of Tehran. Of these, 328 samples were collected. The tool of the current research was a researcher-made questionnaire, the validity of which was calculated using the CVI coefficient for components and items between 77 and 95, and the reliability of the questionnaire was obtained using Cronbach's alpha of 0.85, which indicates that The questionnaire used is reliable. Cronbach's alpha for the questionnaire components was calculated between 0.56 and 0.93. Finally, after collecting the data, the relationships between the variables were measured using structural equations with AMOS software with version 24.

The results showed that in order to form a local pattern, the factors affecting parents' participation in the online education process of elementary schools were confirmed as a central phenomenon in the two dimensions of educational care and supervision and control of children. The phenomenon of parental participation in this field is formed under the influence of factors such as parental ability, parental support and infrastructural factors. On the other hand, the use of solutions such as cooperative methods and methods based on social activity under the title of parents' participation solutions leads to the understanding of the necessity of parents' participation.

These results, with their high validity and reliability of modeling, can be a powerful tool for investigating parents' participation and its role in online education in subsequent researches.Keywords: parental participation, online education, cooperative education.

This research aimed to study the components of entrepreneurial attitude development in secondary high school students. The study was applicable in terms of purpose, quality-quantitative in terms of approach, and descriptive in terms of data collection. In the quality section, the studied population was the experts, planners and teachers of entrepreneurship, and they were selected by snowball sampling. The sampling process continued until data saturation was achieved. Data was collected through semi-structured interview and was analyzed using a three-step coding process of open, central and selective. In the quantitative section, the population was teachers of entrepreneurship in high schools in the regions of 1, 4, 5, 6 and 18 in Tehran in 2021. 250 teachers of entrepreneurship were selected based on voluntarily sampling and they completed the researcher’s questionnaire. The data were analyzed by confirmatory factor analysis and Amos24. The results showed that the components of the development of the entrepreneurial attitude of high school students have a central phenomenon of developing cognitive, personality and entrepreneurial skills and seven categories of problem solving skill, positive attitude of teacher and student to entrepreneurship, imagination, inner motivation, entrepreneurial personality traits, career perspective of students and applied education of entrepreneurship. The results of confirmatory factor analysis showed that these categories can explain the cognitive, personality and entrepreneurial skills of students. Therefore, in order to develop the entrepreneurial attitude in high school students, it is necessary to pay attention to the categories related to cognitive, personality and entrepreneurial skills. In order to realize the development of students' entrepreneurial attitude, it is suggested that teachers strengthen and improve these categories in the process of teaching and learning.

The current research was conducted with the aim of presenting a model for designing learning centers for faculty members of Allameh Tabatabai University in order to empower them. A mixed method and an exploratory design were used to conduct this research. The statistical population in the qualitative section was all related research documents from 2000 to today and university professors, specialists and informants familiar with the learning center and faculty members. This research also used a semi-structured interview. Sampling in the qualitative part was done purposefully and data analysis in this part was done in the form of foundation data with thematic analysis approach in three stages of open, central and selective coding. The statistical population of the research in the quantitative part of the research included the faculty members of the university, 250 of whom were randomly selected. Spss and Amose software were used for data analysis in this part. In the qualitative section, 5 main codes representing the dimensions of empowerment and 9 central codes representing the components of the dimensions were identified. Also, the number of 50 open codes was determined, which was reduced to 28 after the merger. Based on the dimensions, the skills needed by the faculty members of Allameh Tabatabai University in the direction of empowerment are: social factors, economic factors and educational factors. The results of the factor analysis which was done by Emus software also showed that the measurement scale in all factor analysis indicators is at a desirable and acceptable level.

The restrictions caused by the coronavirus resulted in physiological and psychological problems for all ages in the world. This study aimed to investigate the effect of four weeks of aerobic exercise and caffeine supplementation on body composition and psychomotor performance of obese students who have recovered from COVID-19.

The current research was a quasi-experimental design with a two-step pre-test-post-test measurement. 40 obese students recovered from COVID-19 from Imam Khomeini International University of Qazvin Province eligible to participate in the research with a mean age of 22.57±1.45 years, weight of 90.74±7.53 kg, height of 171.05±4.93 cm, and body mass index of 30.51±2.36 were randomly assigned into four groups of 10 people including 1. Exercise-Supplement, 2. Exercise-Placebo, 3. Exercise, and 4. Control. The interventions included four weeks of aerobic exercise and caffeine or placebo supplementation. To analyze the data, a dependent t-test was used to check the intra-group difference, and an ANOVA statistical test was used to check the inter-group difference.

The results of the dependent t-test showed that there was a significant difference in all variables (body composition, and psychomotor performance) in the pre-test and post-test in the Exercise-Supplement, Exercise-Placebo, and Exercise groups (p<0.05), but in the pre-test and post-test, there was no significant difference in the control group for all variables (P>0.05). Also, intergroup analysis with the ANOVA test showed that there is no significant difference between groups in weight (p=0.144), fat percentage (p=0.053), and body mass index (p=0.993). However, there was a significant difference in psychomotor performance (duration of correct choice, number of correct choices, number of correct withdrawals, static balance, and dynamic balance) (p<0.05).

According to the obtained results, both aerobic exercise and aerobic exercise with caffeine supplementation can help reduce weight, body fat percentage, and body mass index, and improve psychomotor performance in obese people who have recovered from COVID-19.

Strengthening the international cooperation of universities and higher education institutions has always been one of the important research priorities . The present research has been carried out with the aim of identifying the role of sabbatical in clarifying administrative management mechanisms and inter-university communication networking of medical sciences universities. The current research was conducted with an exploratory qualitative research approach and in a special way on the basis of the narrative research method to collect the narratives and lived experiences of the faculty members of medical sciences universities in Tehran who had experienced the opportunity to study abroad through semi-structured interviews with them. In order to clarify the administrative mechanisms affecting the networking of universities of medical sciences with other universities abroad, 14 faculty members of universities of medical sciences in Tehran were interviewed. Data analysis was done by inductive method and conventional methods in coding grounded theory. After categorizing the categories based on the conceptual framework of the research in the three roles of "inventor", "developer" and "guide", the results showed the sabbatical in the three mechanisms of "legal capacity building", "structural capacity building" and "policy building capacity" of management. The administration forms the networking of universities of medical sciences. The experience of the faculty members participating in the study opportunity program indicated the innovative role of this program in legal capacity building (change and amendment of laws), the developmental role of this program in building the capacity of the executive structures of the system, and its guiding role in the direction of capacity building of policies. The achievements of the study opportunity program in the networking of universities require that the system of the Ministry of Health, along with the necessity of allocating funds and encouraging academic staff members, takes serious action to remove obstacles and facilitate it.

There was a significant difference between LDL, HDL, TC, TG and TSH in the supplement and exercise groups (p≤0.05 In general, it can be concluded that eight weeks of moderate-intensity aerobic exercise combined with vitamin D3 improves lipid profile, TSH changes and depression in obese women.

Objective :

The COVID-19 pandemic resulted in home quarantine, which affected elite athletes in terms of physical and mental health and nutrition. This study aims to investigate the role of emotional eating in predicting the physical activity and psychological health of elite athletes during the COVID-19 pandemic in Iran.

Methods :

This is a descriptive/correlational survey. The study population includes all elite athletes in Iran. Using Cochran’s formula, the sample size was determined 384, and samples were selected by random cluster sampling method. To measure the physical activity of participants, the international physical activity questionnaire (IPAQ) was used. The impact of event scale-revised (IES-R) and the depression, anxiety, and stress scale-21 (DASS-21) were used to measure the psychological health of participants. To measure their emotional eating, the emotional eater questionnaire (EEQ) was used. Pearson correlation test, linear regression analysis, and multivariate analysis of variance were used to analyze the data in SPSS software.
