The low adoption of climate-smart agriculture (CSA) technologies by farmers in developing regions where agrarian livelihoods are threatened by climate-related disasters such as drought remains a concerning enigma. Adoption patterns are not commensurate with merits of CSA on food security and climate resilience and attention to Socio-psychological features in relation to behavioral and attitudinal patterns in CSA adop-tion remains scarce. Accordingly, this research aimed to study adoption of CSA using the extended technology acceptance model in Sistan plain. The study was conducted on the farmers in the Sistan plain in Sistan and Baluchistan province (N = 6000). The sample (361 farmers) was taken by the proportionally allocated stratified random technique. The results revealed that variables of perceived usefulness, perceived ease of use, farmers’ subjective norms, and attitude had significant effects on their intention to apply CSA practices. In addition, farmers’ subjective norms and attitude towards CSA had significant effects on perceived usefulness, perceived ease of use. This shows the critical role of social influences in shaping attitudes and behavior for CSA adoption and could be useful in educating farmers on climate change.

As cultural, economic and social centers, cities play a significant role in attracting tourists. With the increasing need for sustainable development, paying attention to ecological aspects in the development of urban tourism is proposed as a vital and necessary approach. Sustainable urban tourism with an emphasis on ecological power not only attracts tourists, but also protects the environment and the ecological balance of cities. Therefore, in the current research, an effort was made to look from the inside out and with new strategic thinking, while identifying internal resources and capabilities, macro environmental factors and positive points, in addition to searching for the functions, to provide positive solutions to city managers and officials. In relation to the realization of sustainable urban tourism development in District 22 in Tehran. This research is applied in terms of purpose, and descriptive-analytical in terms of data collection, and questionnaire is a means of collecting information. Meta-SWOT model, PESTEL analysis, GIS-10.8 and Global Maper.25 have been used for data analysis. The results showed that among the internal resources and capabilities of sustainable urban tourism development in region 22, with emphasis on its ecological power, they have different weights, so that factors such as the presence of natural lands in the north, west and east of the region and the possibility to Ecological coherence (1/70), the existence of Martyrs' Lake in the Persian Gulf (1/68), the existence of Chitgar forest park in the region, the existence of extensive military lands as a potential for the development of the base environment, and the existence of recreational and public tourism places in the region jointly with The score (1.38) has the highest weight, which indicates that it is valuable, inimitable and organizational appropriateness compared to other factors in the development of sustainable urban tourism in region 22, and should be at the top of the executive actions of managers and officials in order to realize it.

The shock wave or plasma pulse method was presented for the first time in oil wells to solve the problem of worldwide pressure drop and well production. In this study, the technology of underwater electric wire explosion (UWEWE) has been investigated to generate shock waves by using a sudden discharge of very hot plasma energy at a point and then creating a shock wave. The constructed plasma emitting device consists of two electrodes, a set of high voltage capacitors with a voltage of 5 kV and a capacity of 80 microfarads, an electronic block, a Rogovsky coil installed in the electric discharge circuit, and a relay block. For aluminum wire with a diameter of 400 and 500 mm and a length of 30 mm, with a pulsed current at a discharged voltage of 3.8 kV, the total energy deposition is 400 and 500 J, with the energy conversion efficiency of 68 and 66.3%, respectively, and a maximum power of 168 MW.

Diabetes is a significant health problem that can lead to death and serious complications. To prevent these outcomes, patients need to adopt specific self-care behaviors. Patients' knowledge about the disease and self-care methods is crucial for achieving desired treatment outcomes. Therefore, this study aimed to determine the state of awareness and self-care performance in patients with type II diabetes.

This cross-sectional study included 299 patients with type 2 diabetes referred to the diabetes clinic of Dezful City in 2022, selected through convenience sampling. Data were collected using a questionnaire related to self-care knowledge and practice and analyzed using SPSS 16 software with a 95% confidence level.

The results showed that 88.6% of participants were under 60 years old, 67.2% were male, 57.9% lived in urban areas, 54.2% were single, 56.2% were illiterate, and 34.1% had been diagnosed with diabetes for 1 to 5 years. It was found that 93% and 99.3% of participants did not achieve high self-care knowledge and performance scores, respectively. The highest average score was for knowledge about diabetes (3.87 ± 1.35), while the lowest average score was for foot care practice (12.70 ± 3.6).

This study showed that patients with type 2 diabetes have low self-care knowledge and performance. Therefore, it is necessary to modify and improve the self-care programs for these patients.

Knowledge, positive attitude, and proper practice are the most important factors in controlling cardiovascular complications in chronic diseases such as diabetes. So, this study investigated the knowledge, attitude, and practice of cardiovascular disease prevention in patients with type 2 diabetes.

In this descriptive-cross-sectional study, 385 patients with type 2 diabetes who visited the Diabetes Clinic of Ganjavian Dezful Hospital from January 2023 to April 2024 were selected by convenience sampling method. To collect data, the demographic information questionnaire and the questionnaire by Koohi et al. (2021) related to the knowledge, attitude and practice of prevention of cardiovascular diseases were used. The Cronbach's alpha of the questionnaire was >0/6 for all dimensions of the questionnaire, and its CVR and CVI in this study were 0/90 and 0/85. Data were analyzed using SPSS version 16 software and p-value of less than 0.05. Descriptive statistics including frequency, mean, and standard deviation as well as inferential statistics such as Pearson correlation, independent t test, and ANOVA were used to analyze the data.

This study showed that 57.1 percent of the participants were in the age range of 40 to 60 67/5 percent of whom were women. Patients had a high level of knowledge and attitude toward preventing cardiovascular disease (20/06 ± 5/42) and (46/80 ± 4/99), respectively); however, their performance level was not high (8.65 ± 5.03). A significant positive relationship was also observed between knowledge and attitude (r = 0/6, P= 0/001).

Despite patients’ high level knowledge and attitude toward the prevention of cardiovascular diseases, their performance in this field is not appropriate, and this issue requires planning by hospital managers

This paper proposes a stochastic optimization problem for local integrated hydrogen-power energy systems. In the proposed model, the integrated system tries to reduce the day-ahead operation costs using dispatchable resources, renewable energy resources, battery energy storage systems, demand response programs, and energy trading with the upstream network. Also, the integrated system is able to transact electricity with the upstream network to get more benefits. When the generation of renewable resources is high, the integrated system can convert the surplus electricity to hydrogen by power-to-gas units. The generated hydrogen can be sold to different industries or stored in the hydrogen tank storage. During peak hours, the stored hydrogen can be imported into the gas-to-power unit to generate the required electricity. The sector coupling between electricity and hydrogen provides more flexibility for integrated systems and is an effective solution to control the uncertainty of renewable energy resources in order to increase the power and energy flexibilities. The simulation results show that the proposed sector coupling provides the opportunity for electricity and hydrogen trading for integrated system. The benefit of the integrated system by electricity and hydrogen trading with the upstream network and different industries are $ 88.39, and $ 6846, respectively.

Background and Objectives Stuttering, due to different reactions of stutterers in different ages, needsage-specific treatment. Considering the lack of study on the effect of the Camperdown program ontreatment of stuttering in adolescents in Iran, the present study aims to investigate the effect of theCamperdown program on the stuttering severity of Kurdish-speaking adolescents with stuttering in Iran.Subjects and Methods This is a single-subject study with an A-B-A design which was conducted on 4Kurdish-speaking adolescents with stuttering. The pre-test assessments were first done. Then, theyreceived 40 sessions of intervention using the Camperdown program. The measures were was thepercentage of stuttered syllables, the 9-point severity rating scale, and the speech naturalness scale(NAT). The data were analyzed based on visual analysis and descriptive statistics.Results The intervention was effective in reducing the stuttering severity of all four subjects (percentageof non-overlapping data=100%) and the scores of NAT scale in subjects after intervention was significantlydifferent from their pre-intervention scores.Conclusion The Camperdown program is effective in reducing the stuttering severity of Kurdish-speakingadolescents with stuttering.

Religion has always existed in human life, and no one is without religion. The true and valid religion is the one that has been revealed by God for the present time. This study, applying an analytical-descriptive method and library-based research, provides an overview and analysis of the Zoroastrian religion, which is one of the extant religions. The probable history of this religion dates back to three thousand years ago. The Avesta, the sacred scripture of Zoroastrianism, consists of five sections. The first section, known as Yasna, contains seventeen hymns that some researchers believe to be the work of Zoroaster himself. The language of the Gathas is Indo-Iranian, distinct from Persian, and it is very obscure and full of secrets. Belief in one God, the prophethood of Zoroaster, the existence and immortality of the soul, the afterlife, heaven and hell, judgment, and the sending future prophets by God are among the tenets of this religion. Deviations from the core teachings of Zoroastrianism include belief in kinds of dualism, excessive veneration of fire, non-burial of the deceased, consanguine marriage, the difficulty or impossibility of some laws, the validity of Magi decrees, and similar issues. Zoroastrianism does not proselytize and instead refers its adherents to future prophets in subsequent millennia. Therefore, such a religion is fundamentally incompatible with the demands of the contemporary era, and the assertion of its gReligion has always existed in human life, and no one is without religion.

So far, nanoparticles of porous zinc sulfide have been synthesized in solvent mediums. Cyclohexane was used as the first insoluble medium for the reaction between zinc precursors, zinc chloride (ZnCl2) and zinc nitrate (Zn (NO3), 2.6H2O), and sulfur precursors, thioacetamide (C2H5NS), thiourea (C2H5NS) and Na2S.5H2O. Dodecyl amine has been used as the structural guiding agent. Various analyzes such as X-ray diffraction, nitrogen uptake and desorption, as well as transmission electron microscopy and field emission scanning electron microscopy have been used to analyze the morphological features and characteristics of the obtained products. The results of X-ray diffraction prove the successful synthesis process in the non-solvent cyclohexane medium. The results of nitrogen adsorption-desorption isotherms show that the synthesized materials using different precursors have different pore sizes and specific surface area. The highest specific surface area of about 190 m2g-1 was obtained by the proposed synthesis procedure. The synthesis and porosity formation mechanism of the mesoporous ZnS particles has also been discussed and it was demostrated that the insoluble by-product has the main role in the porosity induction in the structure.

One of the enemy's methods to undermine Islam is sectarianism and exacerbating conflicts among Islamic sects. The formation of Takfiri and Wahhabi groups, along with support for Shia extremists such as the alSarkhi sect, are among the measures pursued by Western countries in line with their anti-Islamic policies. This research, conducted using a descriptive-analytical methodology and library research, aims to introduce and critique the personality and ideas of Mahmoud Sarghī. The investigations have revealed that al-Sarkhi is a socially and morally undesirable individual. Politically, he is affiliated with the Ba'ath Party in Iraq and has a record of multiple betrayals. He lacks proper religious education and has no scholarly or academic background, which undermines the significance of his ideas. However, to gain a better understanding of his personality and deviant movement, some information has been provided.

Rural women’s small businesses make huge contributions to the rural development. However, success and survival of these businesses has been a concern. Hence, it is critical to understand the factors influencing success of rural women’s small businesses. The present study examined whether two psychological sources, namely entrepreneurial resilience and empowerment were positively related to the entrepreneurial success of rural women. The statistical population of the study included all rural women entrepreneurs in Sistan region, Iran  (N = 1546). Then, 250 people were selected as the sample using a non-probability convenience sampling procedure. The research instrument was a questionnaire, which its face validity was confirmed by a panel of experts and its reliability was confirmed by calculating the Cronbach's alpha coefficient (α > 0.74). The results of structural equation modeling showed that entrepreneurial resilience and empowerment were positively and significantly related to the entrepreneurial success of rural women. The results also indicated that empowerment was indirectly related to the entrepreneurial success of rural women through the resilience. Therefore, it is suggested that rural women entrepreneurs’ psychological resources, especially resilience and empowerment be strengthened and developed in order to improve the level of their entrepreneurial success.

Burns are one of the most important health problems in communities. Traumatic injuries, especially Traumatic Brain Injury (TBI) associated with burns, may increase disability and mortality. In addition to preventing burns, any action for a better treatment approach and early detection of concomitant traumatic injuries can reduce complications, disability, and treatment costs. We aimed to investigate the outcome of children with burn injury with and without TBI.

In this cross-sectional study, 392 children with burn injuries treated at Motahari Hospital in Tehran, Iran from 2018-2019 were enrolled. Patient demographics, burn injury information and TBI-related information including head trauma and fracture were recorded in a checklist. Patients were divided into two groups of death (24 people) or discharge (368 people) in terms of outcome and the underlying variables were compared in the two groups.

There was no significant difference between the mean age of patients and gender in the two groups. The difference in the length of hospital stay, inhalation injury and skull fracture in the two groups was not statistically significant. The mean burn severity based on Total Body Surface Area (TBSA) and the frequency of TBI in the deceased group was significantly higher (P=0.001).

The severity of burns based on TBSA and TBI is associated with increased mortality among children with burn injuries. The results suggest the need to examine children with burn injuries for TBI using clinical examination or imaging.

Regarding the crucial role of human resources in any organization, addressing issues that lead to reducing occupational injuries and increasing their productivity in the workplace is of great significance. However, primary studies show that little research has been done in this area. In this regard, investigating the effect of employing workplace ergonomic principles on occupational productivity of experts through the mediating role of occupational stress and burnout in Kerman Agricultural Jihad Organization was determined as the aim of present study. Present research is an applied and causal-correlational study that was carried out using a cross-sectional survey and structural equation modeling. The statistical population of the study was the experts of Kerman Agricultural Jihad Organization (N=1418). The sample size was estimated to be 306 cases using Krejcie and Morgan sampling table. The samples were selected by stratified random sampling approach. The data gathering instrument was a questionnaire whose face and content validities were confirmed by a panel of experts. The reliability of instrument was achieved using Cronbach's alpha coefficients and composite reliability indices. Structural equation modeling findings demonstrated that the direct effect of ergonomic principles on productivity was positive and significant. The direct effects of ergonomic principles on occupational stress and burnout were negative and significant. Furthermore, the direct effects of occupational stress and burnout on productivity were negative and significant. The direct effect of occupational stress on burnout was positive and significant and the indirect effect of ergonomic principles on productivity was significant, as well. Finally, the findings revealed that three independent variables (ergonomic principles in the workplace, occupational stress, and burnout) could account for 61% of the variance in productivity of experts in Kerman Agricultural Jihad Organization.

Endotracheal extubation is associated with high complications such as sore throat, cough, and hoarseness.

This study was performed aimed to compare the effect of green tea and licorice gargle on sore throat, cough, and hoarseness after endotracheal extubation.

This randomized controlled clinical trial was performed in the operating rooms and surgical wards of two hospitals in Tehran during 2020-2021. A total of 102 candidates for elective surgery were allocated to licorice, green tea, and control groups by simple random allocation. The scores of sore throat, cough, and hoarseness were assessed one hour after endotracheal extubation. After the gag reflex returned, 30 cc of the prepared solutions was given to the patients to gargle for 30 seconds. The intervention was repeated two hours later. The scores were assessed in the three groups immediately after the first stage of the intervention (post test1), and two hours after the second stage of the intervention (Post-test 2). Data were analyzed by SPSS software (version 16) and One-way Analysis of Variance-ANOVA, Repeated Measure ANOVA and post hoc test. P<0.05 was considered statistically significant.

There was significant difference between the three groups regarding sore throat, cough, and hoarseness variables in the post-test 1 and post-test 2 stages (P<0.05). The intervention groups had significantly reduced scores in three main variables compared to the control group (P< 0.05), but the difference between the two intervention groups was not significant (P> 0.05). Implications for Practice: Gargle of licorice solutions or green tea is recommended as a non-pharmacological and low-cost intervention to reduce post-extubation complications.

The emergence of agricultural e‐commerce can solve the challenges of agricultural marketing especially in developing countries such as Iran. The aim of this study was to extend the Technology Acceptance Model (TAM) through adding the variables social influence and facilitating conditions to understand farmers’ behavioral intention towards using agricultural e-commerce. This descriptive-correlational research was conducted through a cross-sectional survey. The statistical population of the study was Jahrom citrus growers, Iran, (N=3566). The stratified random sampling method was used and 360 respondents selected in the survey. The research instrument was a structured questionnaire, who’s the research instrument was a structured questionnaire, whose face, convergent, and discriminant validity of the questionnaire were confirmed. Cronbach's alpha and composite reliability were obtained using SPSS24 and AMOS24 software, respectively to examine the reliability of research tool (0.75< α< 0.85). The results showed that the extended form of TAM constructs was significant in explaining farmers’ behavioral intention. This means that attitude, perceived usefulness, facilitating conditions, social influence and perceived ease of use explained 50.3% of the variance in behavioral intention. The hypotheses of the extended TAM constructs showed that social influence and facilitating conditions have a positive and significant effect on intention towards using agricultural e-commerce. In this context, the government and agricultural e-commerce planners need to raise the awareness of all social influence groups about the benefits of using agricultural e-commerce through all media. In addition, providing technical and educational e-commerce facilities for farmers is recommended.

The aim of this study was to determine the relationships and genetic diversity between and within wild species of Aegilops using EST-derived TRAP molecular markers.

In this study, genetic diversity and relationships among eight wild species of Aegilops collected from 14 provinces of Iran were evaluated using 24 TRAP primer combinations.

The mean of PIC for studied primers was 0.95 and the lowest and highest values ​​of this index were related to TRAP20 (0.92) and TRAP10 (0.97), respectively. Also, the mean of MI was 10.77 and the lowest and highest values ​​were related to TRAP3 (6.95) and TRAP17 (17.34), respectively. The molecular analysis of variance showed 60% variance between species and 40% variance within species. Estimated genetic parameters showed that the highest levels of Na (1.07), Ne (1.26), I (0.23) and uHe (0.16) belonged to Ae. truncialis and the maximum Nei gene diversity (0.14) was related to Ae truncialis, Ae. umbelulata and Ae. neglecta. Minimum values ​​of Nei gene diversity (0.09), Shannon index (0.14), No. of effective alleles (1.16) and No. of observed alleles (0.79) was observed for Ae. crassa. The least genetic similarity was observed between Ae. crassa with Ae. cylandrica and Ae. umbelulata and the most similarity between Ae. triuncialis and Ae. umbelulata. Being in the same group of Ae. umbelulata and Ae. truncialis with cluster analysis and PCOA confirmed the high genetic similarity of these species.

The results showed high genetic diversity among and within species. Molecular analysis of variance revealed higher genetic diversity between species, indicating low gene flow and Fst, as well as a high genetic differentiation between species.

Recent droughts have aroused extensive concerns on crop and food production in the world. Since the agricultural sector is the leading water consumer in Iran and farmers are one of the most vulnerable groups to drought, applying drought adaptation strategies changes their resilience and viability. The present study aimed to investigate the effects of drought adaptation strategies on farmers' livability and resilience in the Sistan region, Iran (N = 6000). Therefore, a sample of 361 farmers was taken by the multi-stage cluster randomization technique. The research instrument was a questionnaire which its content and face validity was confirmed by a panel of experts and discriminant validity (AVE). In addition, evaluating its reliability using Cronbach's alpha and the Composite reliability indices revealed that the values are within the acceptable range. The results indicated that the means of the physical, and environmental livability, responding, and recovery were significantly lower than the mean interval of the variables. The findings of SEM showed that 45.8% and 38.7% of farmers' livability and resilience to drought conditions depend on the adaptation strategies used by them, respectively.

Providing energy for pumping water to pressurized irrigation networks in the agricultural sector on the one hand, environmental crises and global concerns about the consequences and effects of fossil fuels on the environment on the other hand, have led to the necessity of changing mental patterns about the use of clean and renewable energy. In the meantime, solar energy is a response to the challenges posed. The purpose of this study was to analyze the farmers’ behavioral intention towards the use of solar cells in irrigation systems. The statistical population was included (N= 7172) irrigated farmers who were selected (n=365) farmers as a sample group using the table of Krejcie and Morgan. The research instrument was a researcher-made questionnaire which its content validity was confirmed by a panel of agricultural extension and education experts and discriminant validity (AVE). Also, its reliability, using Cronbach's alpha and the Composite reliability indices was obtained in the optimal range. Data processing in both descriptive and inferential statistics using SPSSWin22 and LISREL8.8 software and achieve goals with structural equation modeling was conducted. According to the analyses, a significant correlation between the variables of “behavioral intention”, “attitude”, “subjective norm”, “perceived behavioral control”, “perceived ease of use” and “perceived usefulness” were observed. Also, based on the results of modeling, the independent and mediating variables of the study had a significant effect on the farmers’ behavioral intentions. Those five variables explained 64 percent of the total variance of farmers' behavioral intentions in using solar cells.

This study aimed to design a model of intelligence protection culture for students of military academies of the Islamic Republic of Iran. 255 concepts were extracted and coded from interviews with experts and related literature. In the second step, the concepts were aggregated, compared, and categorized. In the third step, the key concepts were refined, and 61 indicators were extracted. Finally, the components that had common and similar concepts were organized under one category and 4 dimensions including structure, context (environment), content (behavior) and management and leadership were extracted and the final model was presented.

Hedgehog is an insectivore animal (it can be carnivore or omnivore in different live conditions) from true quadruped order. Anatomical structure of different system of this animal is not studied yet. hedgehog tongue was studied in this research. 5 tongue of puberty hedgehog was provided; First biometrical measurement was done then different type of lingual papillae was distinguished under stereomicroscope. samples fixe in paraffin and parafinized blocks were provided; these blocks were sectioned as serial. Also for counting of taste buds, circumvallate papillae were sectioned serially as craniocaudal and mediolateral. This research results were showed that hedgehog tongue has tree lingual papillae. They were filiform, fungiform and circumvallate papillae. Number of fungiform papillae was 78.33± 3.78 and they distributed in base and apex of tongue more than middle part. Also, it showed that fungiform papillae distributed in lateral border of mid portion of tongue extremely. Average of taste buds on fungiform papillae was 3.72±1.32. Number of circumvallate papillae was 3.272±1.32 that they were observed just in root of tongue. Number of circumvallate papillae taste buds was 14 ±5.52 in mediolateral secretions and 11.8±5.89 in craniolateral sections. This study results were appeared that taste buds of hedgehog tongue has tree type cells. They were sensory cells (neuroepithelial cells) supporting cells and basal cells. Lingual salivary glands in hedgehog tongue were serous, mucus and seromucus that serous secretory units were abundant in rostral portion and in caudal portion, mucus secretory units were abundant.

One of the most important assets in any organization is the human resources and the success or failure of any organization largely depends on the performance of the human resources of that organization. Lifestyle as an effective factor in staffs' behavior facilitates their organizational commitment. In the armed forces, which deals with the vital issue of security and defense, the value of committed and religious human capital becomes more apparent. This study was conducted to investigate the effect of lifestyle on the level of organizational commitment of AJA staff. The statistical population of this study was the staff of the first region of Nedaja Imamate in 2019, from which 350 people were selected using stratified random sampling method. The research method is correlational and a questionnaire was used to collect data. The results showed that there is a significant relationship between attitudes, tendencies, activities and human relations with organizational commitment and property has a significant relationship only with continuous commitment. As a result, lifestyle has a direct and positive effect on the organizational commitment of the staff of the First Region of Islamic Republic of Iran Navy and accordingly, strengthening the lifestyle in the stated dimensions will increase the organizational commitment of AJA staff.

In clustering algorithms for wireless sensor networks, cluster heads close to the sink node usually encounter much more relay traffic and therefore lose energy rapidly. To address this problem in wireless sensor networks, distance-aware clustering approaches such as EEUC that adjust the cluster size according to the distance between the sink node and each cluster head have been proposed. However, the network lifetime of such approaches is highly dependent on the distribution of the sensor nodes because in randomly distributed sensor networks the approaches do not guarantee that the cluster energy consumption is commensurate with the cluster size. It might be necessary, for example, for sensors to be randomly distributed over the surveillance region (e.g., via aircraft). To solve this problem in wireless sensor networks, a new method called distribution based clustering algorithm (DBCA) was proposed in the present research which is not only aware of the distance but also the density of the sensor nodes. In DBCA, clusters have limited sensor nodes that are determined by the distance between the sink node and the cluster head. The simulation results show that DBCA is 25% to 45% more efficient than previous algorithms in terms of power consumption under different operating conditions.

Hypertensive is among the leading causes of mortality and exploring alternative strategies for its better control has ever had special importance. The aim of this study was to investigate effect of acute resistance exercise session with and without blood flow restriction (BFR) on blood pressure in pre-hypertensive and hypertensive women.

 24 volunteer subjects, were randomized into two groups (n=12) of pre-hypertensive (blood pressure: 12.5-14 mmHg, age: 54.5±1.88 years and BMI 27.0±2.01 kg/m2) and hypertensive (blood pressure: 14.5-16 mmHg, age: 55/25±2.05 years and BMI 27.51±1.93 kg/m2) patients. All three groups experienced three different sessions with a week washout interval including on control, resistance training (3 sets at 20-30% of 1RM) with BFR and resistance training (3 sets at 70% of 1RM) without BFR. Blood pressure and heart rate were recorded at resting condition, between sets rest intervals, at respectively 15, 30, 45, 60 and 120 minutes, post exercise and also at resting condition 24 hours post exercise. Data were analyzed by repeated measures analysis of variance test at the P <0.05.

There were significant falls in systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial blood pressure (MAP) level as well as heart rate (HR) post exercise in both groups, with sharper drops observed in training with BFR session (P<0.001).

It seems that resistance training with BFR could be more beneficial to lower patients’ blood pressure.

In the new millennium organizations, there is a strong emphasis on intangible assets such as innovation, creativity, entrepreneurship and knowledge capital. These organizations focus on human resources and thus take steps to overtake their competitors. Since the succession program trains and prepares the right people to fill key positions, it can be an effective strategy for nurturing competent managers and leaders. This study aims to design a model of talent-spotting and succession program in public organizations. In this meta-combination research, previous related literature and its findings analyzed with emphasis on public organizations. The research statistical population are related studies and the data collection tool are library secondary data studies. In this regard, 56 articles, in line with the purpose of the study, were selected from among 327 researches in talent-spotting and succession program and evaluated. Finally, the initial model was presented and the results of the meta-combined method validated by the opinion of experts. The results indicate a comprehensive model of talent-spotting and succession program in six categories including internal organizational factors; talent-spotting process; succession competencies; development and empowerment; sustainability and strategic alignment, with 20 concepts and 244 classification codes. The findings of this study can provide a good roadmap for identifying and establishing a talent-spotting and succession program in public organizations with a view to the future.

The study aimed to evaluate students'' external effectiveness of agricultural education and its effect on their attitudes toward future career. The statistical population was agricultural students of Iran public universities in 2020 (N=236973). From whom 386 students were selected as a sample through stratified random sampling method. The assessment tool was a questionnaire whose face and content validity was confirmed by academic experts and discriminant validity (AVE= 0.5-0.68) was used for determination of structure validity. Reliability of questionnaire was determined by ordinal theta (Ɵ= 0.75-0.91) and composite eliability (CR= 0.74-0.91). The variables were measured on a five-point Likert scale (from 1 = very low to 5 = very high). Data was analyzed by applying SPSSwin23 and AMOS22. To develop structural model, confirmatory factor analysis (CFA) were used in first and second stages for testing measurement models. Results of CFA showed that components of structures were able to measuring of related structures. Results of structural equation modeling (SEM) revealed that educational process had a positive and significant effect on students’ competencies, satisfaction with the field of study, and attitude towards future career. Also, students’ competencies and satisfaction with the field of study influenced their attitude towards future career positively and significantly. It can be concluded that educational process can influence students’ competencies and satisfaction with the field of study and lead positive attitude towards future career.
