Cold stress is one of the major factors limiting rice (Oryza sativa L.) productivity and yield. Two rice cultivars were chosen for this study: a japonica rice, ‘Gerde’, and an indica rice, ‘Shiroodi’, representing tolerant and sensitive cultivars, respectively. In this work, the early physiological and molecular responses of these two cultivars to 4°C cold stress were investigated. We found that cold stress caused a significant decrease in the content of chlorophyll a, chlorophyll b, and carotenoids in both rice cultivars. However, the photosynthetic pigment content in the Shiroodi cultivar decreased to a greater extent, indicating its limited genetic capacity to protect its photosynthetic machinery. During cold stress, the amounts of hydrogen peroxide and malondialdehyde produced by the Shiroodi cultivar were significantly higher than those in Gerde, suggesting a lower capacity of Shiroodi to scavenge reactive oxygen species. The higher level of beta-glucosidase gene expression in the final hours of cold treatment in the Gerde cultivar indicates the involvement of this enzyme in elevating cellular levels of active abscisic acid. Moreover, the significant increase observed in the transcript level of phenylalanine-ammonia-lyase in Gerde indicates the induction of defense responses related to the phenylpropanoid pathway. Altogether, one can conclude that the higher cold tolerance of the Gerde cultivar is multifaceted, involving various factors such as its ability to protect its photosynthetic machinery, its greater capacity for cell protection against oxidative stress, and the expression modulation of genes involved in abscisic acid metabolism and secondary metabolism.

Gene therapy is a hopeful approach for treatment of a wide range of life threatening disease from infectious and inherited diseases to cancer. Multifunctional Envelope-type Nano Device (MEND) is a new carrier as non-viral genetic vector. Moreover, associating peptide structures with the nuclear localization signals (NLSs), which contains various functional groups enables them to condense DNA and specifically transfer genetic material to the nucleus.

In this study, two forms of low molecular weight protamine (LMWP) were used for preparation of MEND carrier. The MEND carriers were then targeted with GE11 ligand to obtain T-MEND structure. The size distribution of the resulting nanoparticles, as well as their transfection efficiency and cytotoxicity, were investigated on the A549 cell line.

Results demonstrated that the size of polyplex carrier’s formulation by both peptides (VV45 and VV32) was below 200 nm and MEND formulations were between 200-300 nm. T-MEND formulations contained VV32 and VV45 peptides showed slightly higher transfection than similar MEND formulations. Also, MEND formulation showed increased transfection efficiency compared to similar PD complexes. The result of metabolic activity test showed that MEND lipopolyplex did not represent any remarkable cytotoxicity.

It can be concluded that multifunctional carriers designed based on LMWP are considered as the safe carrier for gene delivery. Presence of protamine and targeted ligand in the nanoparticulate structure did not increase the risk of cytotoxicity of carriers. So, MEND and T-MEND lipoplexes showed low cytotoxicity and acceptable transfection efficiency at the level of PEI 25 kDa.

 The COVID-19 crisis exerts a marked impact on the quality of life of individuals experiencing grief. Therefore, the present study aimed to assess the effectiveness of life quality improvement treatment and emotion-focused therapy on the cognitive flexibility and vitality of individuals affected by grief due to COVID-19.

 This research employed a quasi-experimental pretest-posttest design with two experimental groups and one control group. In 2021, 30 individuals affected by grief were purposefully selected and randomly assigned to three groups: life quality improvement treatment, emotion-focused therapy, and the control group. Data were collected using the Cognitive Flexibility Questionnaire and the Oxford Happiness Questionnaire. The first experimental group received emotion-focused therapy (Leslie Greenberg, 2012), while the second experimental group received life quality improvement treatment (Fresch, 2006). Data were analyzed in SPSS software (version 27) using analysis of covariance.

The results demonstrated that both emotion-focused therapy and therapy based on improving quality of life had a positive effect on behavioral flexibility and social vitality, and the effectiveness of therapy based on improving quality of life on the vitality of bereaved people was more than emotion-focused therapy.

Considering the effectiveness of both treatments on the flexibility of action and the effectiveness of the treatment to improve the quality of life and vitality of people with grief, psychotherapists can benefit from both two treatments to improve the quality of life and vitality of people with the experience of grief to take.

After soybean and oil palm, rapeseed has the third place in supplying vegetable oil in the world, so that it accounts for 14.7% of the total production of vegetable oil. The current research was carried out using modeling approach in order to simulate the replacement of wheat cultivation with rapeseed cultivation in terms of water and economic productivity in four locations (Aleshtar, Khorramabad, Pol-e Dokhtar, and Kuhdasht) in Lorestan province. APSIM model was used to simulate the growth and yield of wheat and rapeseed crops. The model validation results showed that it accurately simulates wheat and rapeseed grain yield with nRMSE of 8.6%. The results showed that wheat cultivation (3524.4 kg) had a higher grain yield than rapeseed cultivation (2750.2 kg). In addition, wheat cultivation system (1.45 kg m-3) compared with rapeseed cultivation (1.15 kg m-3) had higher water productivity. However, the difference between these two cultivation systems in terms of irrigation productivity was not considerable (0.11 kg m3). Also, economic productivity and net income of rapeseed cultivation system were 0.220 million tomans per cubic meter and 59.9 million tomans per hectare, respectively, while they were 0.014 million tomans per cubic meter and 41.1 million tomans per hectare, respectively, for wheat cultivation system. In general, the results approved that moving from wheat cultivation to rapeseed cultivation can be environmentally and economically sustainable in the agro-ecosystems of Lorestan province, especially in Khorramabad county.

Cheese is one of the most consumed milk products. At present, one of the most widely used salty white cheeses in Iran is the cheese produced by the ultrafiltration method. Non-thermal (cold) plasma is a new method to remove food microorganisms. In this research, the effect of cold plasma on the reduction of microbial load and qualitative and rheological characteristics of cheese samples produced through different tests was investigated. The samples were prepared and produced in Pegah Hamadan Company under two microbial treatments (yeast mold and coliform) and the duration of plasma application at two levels (7 and 13 minutes) and the control sample (lack of contamination, no plasma) and during the storage period of 30 days. They were tested once every ten days with 2 repetitions by colorimetric tests, pH, and tissue test (TPA) and Warner test. The results of the statistical analysis of the obtained data showed a significant difference in the evaluated traits between the control sample and the treatments that underwent the cold plasma process. The value of parameter L* in the samples treated with cold plasma decreased compared to the control sample, also the index b* (yellowness index) did not increase significantly for all cheese samples at the end of the storage period. There was no significant difference in the amount of Springiness between the samples treated with plasma and the control sample, and the amount of gumminess did not increase significantly during the storage period. There was a significant increase in shear modulus, shear stress and shear force between the first day and the 10th, 20th, and 30th days. It can also be concluded that the treatments with coliform contamination have less stiffness and strength than other treatments and the type pollution added to the samples is the cause of this significant difference.

This study aimed to predict marital satisfaction and dissatisfaction based on ego strength, depression, and anxiety symptoms. The study employed a descriptive-correlational design, with 384 participants (306 female, 78 male) selected using available sampling in Tehran in 2022. Couples completed the Golombok-Rust Inventory of Marital State Questionnaire (GRIMS; Rust et al., 1986), ego strength scale (ESS; Besharat, 2007), and depression anxiety stress scale (DASS; Lovibond & Lovibond, 1995). Pearson correlation coefficient and simultaneous regression analysis were utilized to analyze the research data. The results indicated that increasing individual scores in ego strength (p<0.01, r=0.356) led to an increase in marital satisfaction. Conversely, increasing scores in depression symptoms (p<0.01, r=0.498) and anxiety symptoms (p<0.01, r=0.297) were associated with an increase in marital dissatisfaction. Furthermore, marital satisfaction could be predicted by ego strength (p<0.01) and depression symptoms (p<0.01), with these variables explaining 27 percent of the variance in marital satisfaction. In conclusion, the research suggests that ego strength and depression symptoms are significant predictors of marital satisfaction. A thorough examination of these variables in individuals can contribute significantly to enhancing marital satisfaction.

The sharp decrease in rainfall has reached the peak of drought conditions in Fars province, so that the discharge of all rivers in Fars province has decreased between 70 to 100 percent, and due to the limitation of renewable water resources, there is a need for optimal and sustainable use of existing water resources. All reservoirs of dams in Fars province are necessary.

The main purpose and methodology of this research is to design a mathematical planning model for the optimal allocation of water resources of selected dams in Fars province, in order to net advantage of the system on the planning horizon that issues such as time period, reliability level, course currents, number of dams and consider some scenarios. Accordingly, the objective function of the model seeks the maximum advantage obtained for dams based on the parameters set with three indices of scenario, dam and time period.

At first, this model was considered for 5 users (dams) with 4 different scenarios in 10 monthly time periods, in which case the value of the objective function reached 39863110. Then, in order to analyze the sensitivity of the results and show the change of the optimal answer depending on the dimensions of the problem, the model was implemented for 10 users (dams) with 8 different scenarios in 20 monthly time periods in which the value of the objective function reached 82944240. Therefore, with the increase of the dimensions of the problem, a significant increase in the amount of the objective function and the optimal allocation of water resources of the selected centuries occurs in Fars province. Therefore, due to water shortages and recent droughts in Fars province, it is necessary to pay attention to sustainable and equitable development in planning the allocation of water resources and taking into account various indicators simultaneously.

This study aimed to predict marital satisfaction based on dimensions of perfectionism and spiritual/religious perfectionism. This study was descriptive-correlational. Four hundred and four people) 326 female, 78 male) were selected by the available sampling method in Tehran in 2022. All the couples were asked to complete the Golombok-Rust Inventory of Marital State Questionnaire (GRIMS; Rust et al., 1986), Tehran Multidimensional Perfectionism Scale (TMPS; Besharat, 2007), and Spiritual/Religious Perfectionism Scale (SRPS-14; Besharat, 2018). Pearson correlation coefficient and simultaneous regression analysis were used to analyze the research data. The results showed that by increasing the individual score in Self-oriented perfectionism (p<0/05, r=0/110) and Spiritual/Religious Perfectionism (p<0/01, r=0/332) marital satisfaction increases. On the other hand, the results showed that marital satisfaction can be predicted by the variables of self-oriented perfectionism (p<0/05) and Spiritual/Religious Perfectionism (p<0/01). Based on the research findings, it can be concluded that Self-oriented perfectionism and Spiritual/Religious Perfectionism are important predictors of marital satisfaction and the variance of marital satisfaction is 12 percent. Spiritual/Religious Perfectionism is a stronger predictor of marital satisfaction than Self-oriented perfectionism. Investigating these variables in individuals can help significantly in increasing marital satisfaction.

COVID-19 has changed the lifestyles and patterns of interaction in families. This study aimed to investigate the effect of coronavirus anxiety and death anxiety on the conflict between mothers and children aged 7 to 12 years in the home quarantine cause of COVID-19. Thus, 80 couples of mothers and primary school children in Tehran were studied. The results showed that increasing coronavirus anxiety in mothers increases conflict in children, which was represented in their paintings. The psychological symptoms of coronavirus anxiety were related to the position of the child, mother and father on the child’s drawing, and the physical symptoms of coronavirus anxiety disorder were related to the position of the child, mother, and father in the paintings. Also, death anxiety was related to the child's distance from the mother, the child and the father's position. Findings of the study were discussed with Parncutt's “Reflective Consciousness Theory” of maternal hypersensitivity at the time of arousal of fundamental anxiety.

The proponents of Romanticism consider imagination to be the fundamental element of poetry, which allows the poet to create innovative and inspired works to enter the world of the unseen and unheard in order to make a new world. Fasting and the glorious customs of the holy month of Ramadan have been chosen as the theme and the imagery of most Persian poets. This study seeks to answer the following questions: How are the customs of Ramadan and fasting manifested in Persian poetry? And what is the place of poetic imagination in creating relevant images? The method used in this research is descriptive-analytical and the components of Ramadan and fasting were analyzed based on the frequency statistics obtained by software from the poets' works. The poets who paid the most attention to this issue were then selected and analyzed. Rumi, Saadi, Attar, and Qaani were the four who had the most frequency in this field. The main discussion is divided into three main areas under the headings: 1- Rhetorical images of Ramadan and fasting in Persian poetry 2- The customs of Ramadan and fasting 3- Purposes of Ramadan and fasting. Findings indicate that simile, allusion, and poetic etiology have had the most frequency. Also, intentionality, abstinence, and the manner of breaking the fast as rituals of Ramadan, and refinement and cultivation are some of the most important rituals in fasting and Ramadan in Persian poetry recreated by these poets’ imagination.

This problem of how organizations can succeed in a dynamic and unpredictable environment is an issue that is known as the most important challenge in today's world. Therefore, the purpose of this research was to identify the dimensions and components of organizational agility based on human resources development to provide a model of organizational agility in the Islamic Azad University of Tehran province.

In this regard, the statistical population of the research included all employees of the Islamic Azad University of Tehran province, which was about 6735. Among these, using Morgan's table, Cochran's formula, and multi-stage and proportional cluster sampling methods, 386 university employees were considered the sample size. The data collection method was based on a researcher-made questionnaire, research literature, and semi-structured interviews. Cronbach's alpha coefficient of the research tool was calculated as 0.919. After distributing and collecting the questionnaires, the information was checked, and the hypotheses were tested using the structural equation modeling method and with the help of SPSS and LISREL software.

Finally, the research findings confirmed the five dimensions, strategic, information technology, human, organizational and cultural, as the dimensions affecting organizational agility based on the development of human resources.

The research results showed that the strategic dimension has the highest average, and dimensions of information technology, human, organizational and cultural are placed in the next ranks. Finally, confirmatory factor analysis showed that dimensions of organizational agility based on human resources development explain up to 71.282% of the variance of existing indicators of organizational agility based on human resources development.

Mothers of children with autism face many problems that can affect their life. On the other hand, spirituality, as one of the essential aspects of man’s life, has a significant relationship with human health. This study seeks to determine the spiritual well-being of mothers of children with autism.

The type of present study was descriptive-cross-sectional. In this study, mothers were identified among the 7 schools for children with autism, and 200 people participated in the survey in stages, according to the inclusion criteria. The collected data were used using descriptive statistical methods such as setting frequency distribution tables, calculating numerical indices, and independent chi-square and t-test. The paired t-test was used to achieve the goals under SPSS software v. 16.

The Mean±SD spiritual well-being of mothers was 77.17±10.51. Mean±SD spiritual well-being (41.11±5.61) had the highest, and Mean±SD existential well-being (36.06±5.67) had the lowest score. 

 In this study, the spiritual well-being dimension of spiritual well-being was in a better position compared to its Existential Dimension of Health. It can be said that the mothers participating in the present study are richer in spiritual well-being compared to existential health. 

With the growth of financial-behavioral hypotheses and conducting numerous studies to identify the effect of behavioral biases, one of the areas that has been considered by researchers is the field of research related to momentum strategy.The purpose of this study is investigating the disposition effect and anchoring bias separately and in combination with each other to impact momentum profits ad the role of retail investors in this relationship. The statistical population of the study includes companies listed in the Tehran Stock Exchange and the statistical sample includes 136 companies during the years 2007 to 2020. In this study, the effect of disposition effect has been calculated using the approach of Greenblatt and Han (2005) and Frazzini (2006) and the anchorage bias according to the method of George and Hwang (2004). The methodology of Jegadeesh and Titman (1993) has also been used to calculate momentum profits.To test the research hypotheses, the five-factor model of Fama and French (2015) has been used. The results of testing the research hypotheses show that the disposition effect increases the momentum profit. Anchoring bias also leads to an increase in momentum profit. Another result of the research indicates that the interaction effect of anchoring bias and the disposition effect while these two reinforce each other, is also associated with an increase in momentum profit. Finally, when anchoring bias and disposition effect work together, the presence of a high percentage of retail investors increases momentum profits.

Microbial electro-Fenton system as a novel technology can be employed in removal of resistant organic pollutants along with generation of renewable electrical energy through the activity of anaerobic microorganisms. This study aimed at investigating the performance of this process in treatment of synthetic wastewater containing tetracycline and generation of electricity in different electrical circuit conditions.

In this experimental study, a two-chambered microbial electro-Fenton reactor equipped with anodic and cathodic carbon felt electrodes and Nafion membrane, along with 2000 mg/L substrate and anaerobic sludge as inoculum in anodic chamber and 10 mg/L tetracycline in cathodic chamber was used in open, closed, and short circuit conditions. The effect of electrical circuit type on the removal efficiency of tetracycline and generation of electrical energy was investigated during the operation of the reactor.

Microbial electro-Fenton system was found to be more efficient in removal of tetracycline in short circuit condition due to improved generation of current density. In this study, 260 mV and 93.13 mW/m2 in current density of 695 mA/m2 were obtained in short circuit conditions.

The study showed that the microbial electro-Fenton system can be utilized as a suitable method in removal of various pharmaceutical contaminants from wastewater while producing renewable and clean energy in open, closed, and short electrical circuits.

Researchers examined anomalies in the market to understand the market dimensions. Prior studies considered the effects of biases on momentum strategy. Stock liquidity as one of the risk factors for assets was also considered by researchers. The purpose of this study is to examine the role of stock liquidity in the separately and jointly effect of anchoring bias and the disposition effect on momentum profit. The population of this study consists of all companies listed on the Tehran Stock Exchange. Based on systematic election sampling this study covers 136 companies over the period of 2007-2020. In this study, the effect of disposition effect is calculated using the approach of Greenblatt and Han (2005) and Frazzini (2006) and the anchorage bias is calculated according to George and Hwang (2004). This study calculates momentum profits according to Jegadeesh and Titman (1993). To test the hypotheses, multivariate regressions and the five-factor model of Fama and French (2015) have been used. The results of this study show that the disposition effect in stocks with low liquidity increases momentum profit. In addition, anchoring bias in stocks with low liquidity leads to an increase the momentum profit. Findings of this study document that the interaction effect of anchoring bias and disposition effect, while reinforcing each other, is also associated with increasing in momentum profit. Finally, when anchoring bias and disposition effect reinforce each other, and stocks have low liquidity, they do not increase momentum profits.

Home quarantine to manage COVID-19 has increased conflict between mothers and children. This study aimed to research the role of coronavirus anxiety factors and maternal childhood trauma in this conflict due to premenstrual stress. Thus, mothers and their children aged 7 to 12 years in Tehran participated in the study in December 2020. They completed the Premenstrual Rating Scale, the Childhood Trauma Questionnaire (CTQ), the Drawing Family Test, and the Coronavirus Anxiety Scale. The results showed that children often portrayed their conflict with the mother in drawing activities as separation from the mother. Emotional and physical abuse of the mother during childhood caused her child to draw significantly more distant from her mother. Another finding of the study showed that childhood emotional and physical abuse could predict premenstrual stress. On the other hand, the psychological dimension of coronavirus anxiety has also created premenstrual tensions. Premenstrual tensions have also been able to cause mother-child conflict. Interestingly, it was only premenstrual stress that was related to the child's position in the drawing space based on koppitz emotional indicators. Premenstrual tension syndrome seems to directly target the child's self-concept and move him away from being the centre of attention.

Breast cancer is the second common cancer in women at worldwide. Furthermore, patients with breast cancer generally use complementary  and integrative medicine such as homeopathy. It has been shown that homeopathic remedies such as Sepia, Phosphorus and Pulsatilla have great effects in the various diseases such as some of the cancers. However, the cytotoxicity effects of these compounds have not been studied for breast cancer cell lines such asMCF-7. Hence, the aim of this study was to investigate the cytotoxic effects of these homeopathic remedies on breast cancer cell line. 

Materials & Methods

Breast cancer cells (MCF-7) were cultured in DMEM medium and treated with different potencies (30 and 200) of remedies for 24, 48 and 72 h. Cell viability was determined by MTT assay.

The findings indicate that none of the tested compounds had cytotoxicity effect on MCF-7 cancer cells.

This study shows that Sepia, Phosphorus and Pulsatilla as the three of homeopathic remedies have not in vitro cytotoxic effects on breast cancer cell line, and it seems that further studies on different cell lines and also in vivo studies are needed to confirm these findings.

Postmodernism emerged from the womb of modernism and in response to it or as its successor. The postmodern novelist seeks to evoke in the reader the sense that all the solid foundations of life in the contemporary world have collapsed. Poststructuralism paved the way for the formation and emergence of postmodernism; Criticism of the postmodernist current stems from the efforts of poststructuralists who have provided the most important and instructive techniques for this current. Due to the incoherence and uncertainty in poststructuralism, the postmodern school has destroyed the traditional conceptions of language, identity, writing and the like. This paper aims to examine descriptively-analytically the most important components of the poststructuralist approach in the postmodernist novel "Night Orchestra of the Wood Orchestra" by Reza Ghasemi to clarify the aspects of the novel's adaptation to the poststructuralist approach. Be. According to the research achievement, the most important elements of the poststructuralist approach are:the postmodernist novel "Night Orchestra of the Wood Orchestra The question of language, the extent of the author's authority, the identity, the determinability of the texts are challenged in the novel The Night Orchestra of the Wood Orchestra.

Gazestan magnetite-apatite deposit is located in Central Iran and Bafq region, which has been occurred in form of veins, veinlets, and small apatite lenses as well as magnetite in metasomatic rock types such as green chlorite-actinolite rock units. These rocks are situated in the carbonate-volcanic complex of Upper Precambrian-Lower Cambrian Rizo formation. In this study, staged factor analysis and Concentration-Number (C-N) fractal model were used based on core samples for determination of main rock type for Rare Earth Elements (REEs) mineralization. Hence, after normalizing the data by staged factor analysis, the target factors were determined and the factorial map was generated using the C-N fractal modeling. The results showed that the first factor of the sixth step (F1-6) is contained of the REEs with phosphorous. Afterwards, results obtained by the C-N fractal method on the F1-6 indicated that there are five populations for REEs which are compared with different lithological units by evaluation matrix. The evaluation matrix confirmed the compliance of magnetite-apatite units with the high values of mineralization factor. The REEs were accumulated in magnetite-apatite units based on highest Overall Accuracy (OA).

To survive and achieve competitive successes in the dynamic milieu of modern global competition, organizations should not only coordinate with the evolutions of advanced society but also predict the trajectory of changes and transformations. They ought to be able to lead these changes towards the development of desirable performance in employees for giving rise to a better future. Since leadership is considered as a fundamental process of any organization; moreover, organizations praise or blame the leadership of organizations for any success or failure, we can claim that the attitudes and perspectives of individuals in organizations depend on the leadership style of organizations. Undoubtedly, one of the influential factors in the development of human societies is the leadership styles of managers over their subordinates. Occupational hazards are of the main difficulties in occupational health. Many employees spend more than one-third of their lives in their working environments, where they encounter varying occupational hazards. We witness numerous occupational diseases and events in different occupations every day. By inspecting them, we find out that unsafe behavior is usually the main causing factor. According to the occupational health and safety law, occupational diseases are considered as an illness raised because of exposition to any physical and chemical hazards or biological factors, such that they damage the normal physiological mechanisms and bring about health disorders in working individuals. It is because, in addition to triggering musculoskeletal disorders, hyperacusis, cancer, psychological disorders, cardiovascular side effects, etc., these hazards can eliminate the workforce and impose severe financial losses on the economic system of society by resulting in therapeutic expenses. Furthermore, by leading to occupational injuries, occupational hazards can impact the performance of personnel, increase the risk of job burnout, and decrease job satisfaction. Thus, the present study aimed to investigate the effect of the transformational leadership style on predicting occupational injuries in the employees of the Abadan Health Center.  Methods and Materials: The present study had a correlational design and employed structural equation modeling (SEM). The statistical population of the study was all employees of the Abadan Health Center (environmental health, schools, nutrition, mothers, professional health, and statistic offices). The samples were selected by the random sampling method. Since the distribution ratio of employees varied in the different parts of the organization, we took into account the same ratio in selecting the samples to reduce sampling error. Because the study was correlational and employed structural equation modeling, the minimum sample size was 15 individuals for every predictive variable. This research had four predictive variables, including leadership style, safety consciousness, safety-related events, and occupational injuries. Likewise, it had eight demographic variables, including gender, age, education, marital status, history, responsibility kind, employment status, and management experience. Since the statistical population of this study comprised 208 individuals, we, finally, used the Cochranchr('39')s formula and random sampling method and selected 135 employees as the sample size of our research.  To observe this minimum size and due to the fact that some questionnaires would not fully be filled out by the respondents or some employees might be disinterested in participating in the study, we selected more employees, almost 145 individuals, using the random sampling method. The inclusion criteria for the study were working in any organizational segments and being randomly selected from their colleagues, and the exclusion criteria to the study were filling out the questionnaires incompletely and displaying disinterest in taking part in the research. The return rate of the surveys was 95 percent. By considering inclusion and exclusion criteria, we imported 145 employees with an age range between 20 and 50 to the study. Among the employees participating in the research, 79.9% were female, 62.7% were married, 60% had an associate degree, 6.9% had over 20 years of working experience, 34.9% were sanitarian, 32.5% were permanently employed, and 19.4% had management experience. To measure the data, we used the The 12-Item transformational leadership style of supervisor Scale (Bass and Avoli. 1990). The questions of this scale are based on the transformational interaction style of a supervisor with his employees. For example, “my supervisor encourages me to assert my ideas and perspectives respecting the improvement in the safety of working environment” and "my supervisor talks with me about the significance of observing safety problems." This scale is based on a five-point Likert measure ranging from 1 (strongly disagree) to 5 (strongly agree). We calculated the reliability coefficient of this research at 88% using the Cronbach alpha method. Safety consciousne With its five sections (Westaby and Lee 2003) measures the awareness and perception rates of employees towards safety issues. Example questions of this scale are, “I don’t use the equipment I feel they are unsafe.” and “I always use protective equipment or wear the requisite clothes for my job." This scale is based on a five-point Likert scale ranging from 1 (strongly agree) to 5 (strongly disagree). Using the Cronbach alpha method, we calculated the reliability coefficient of this scale at 84%. The safety-related events scale with nine items (Barling et al. 2002) provides us with information on the frequency of the safety-related events during the past month. An example of the questions of this scale is, “how many times have you been exposed to chemical materials or been in place without proper ventilation?” It is based on a five-point Likert scale ranging from 1 (never) to 5 (more than five times). The reliability coefficient of this scale was 77% for the present study. Occupational injuries scale which is a 10-item instrument (Barling et al. 2002) gives us information on the events that employees have experienced in their jobs during the past month. It is a five-point Likert scale ranging from 1 (never) to 5 (more than five times). An instance of the questions of this scale is, “how many times have you suffered from pulmonary injuries?” The reliability coefficient of this scale was 0.77 for this research.We employed the SPSS 18 and AMOS software to analyze the data and determine the regression weights in the structural equations. To investigate the manipulating factors, we provided the sample members with a calm, no distraction, and intimate environment so that they could fill out the questionnaires, conveniently. Likewise, the employees verbally declared their consent regarding their participation in the study. To prevent bias in the responses, we assured the employees that their responses would not be disclosed. Moreover, in compiling the questions of the survey, we attempted not to include value statements; otherwise, they would provoke the employeeschr('39') sensitivity, and; consequently, result in bias in the responses.  

To test the hypothesized effects among transformational leadership style, safety consciousness, safety-related events, and occupational injuries, we employed regression analysis and structural equation modeling. The mentioned coefficients for every path are presented in Table 2. Concerning the findings of the Table, the safety-related events had a significant effect on occupational injuries, and the transformational leadership style had a significant effect on safety consciousness (p<0.05), indicating the significance of the two paths of the model. The transformational leadership style did not have a significant effect on safety-related events. The results of Table 2 demonstrate that the probability value is 0.5 at the 0.05% significance level. This hypothesis is rejected since the probability value is larger than the significance level. Similarly, the safety consciousness hypothesis did not have a significant effect on safety-related events since the probability value was 0.2 at the 0.05% significance level, and; thus, it was larger than the significance level. As observed in Table 2, the results of testing the total indices of the study’s model fit by the path analysis and AMOS software confirms the goodness of fit of the proposed model. Concerning Table 3, it was specified that the Root Mean Square Error of Approximation (RMSEA) in this research equaled 76%, which was smaller than 0.1. Thus, we can conclude that the model’s goodness of fit is perfect.

According to the findings of the study, the employees of the Health center are always exposed to potential occupational hazards and work in hazardous conditions. This can negatively affect the mental and somatic health of the employees of these environments. Furthermore, the transformational leadership styles of managers reinforce safety relationships among the managers and employees of an organization. When employees perceive their managers’ support and infer that the managers of organizations care about their well-being and safety, they are more inclined to preserve their safety consciousness. Therefore, we recommend the organizations’ managers expend proper budgets to supply requisite equipment and minimize the occupational hazards of the employees in healthcare centers. Accordingly, we can claim that this research has both theoretical and applied consequences. Erecting regular sessions and encouraging employees to express difficulties and insufficiencies that exist in the working environment, along with embarking on solving difficulties and creating appropriate processes in organizations for the management of occupational injuries, are examples of applied consequences. Meanwhile, the sufficient financing of budgets paves the way for the periodical somatic and psychological examinations of the employees. At the theoretical level, the findings of this study can assist with the enrichment of the current theories associated with the transformational leadership style. Likewise, we suggest the repetition of similar questionnaires concerning the leadership style and occupational injuries of individuals in organizations at certain time intervals (for example, during biannual programs). Future studies may address the effect of environmental factors on occupational injuries and present new hypotheses within the framework of the researches related to occupational injuries. The main limitation of this study was the use of self-report instruments. Since the under-study variables dealt with humanistic variables, we could not easily conclude regardless of other influential factors such as the environment. Carelessness and negligence in filling out the questionnaires, small sample size, and time restriction are of the other limitations of the study. The present study was confined to the employees of an organization. Hence, we suggest future studies replicate this research in other organizations, as well as larger and more diverse populations, in terms of sample size and gender so that they can compare the results.

Coronary Artery Disease (CAD) is one of the main causes of mortality in the world. The role of Von Willebrand Factor (VWF) is very important in platelet adhesion, microcirculation, and acute stenosis and it contributes to the development of atherothrombotic processes.

We decided to evaluate the level of VWF in diabetic and non-diabetic patients as an effective factor in CAD.

This study was performed on 65 patients (32 diabetic patients and 33 non-diabetic patients), who referred to an Echocardiography and Angiography Department. They were evaluated for the VWF level, blood group, and fasting blood glucose. Patients underwent echocardiography, angiography, and, if necessary, percutaneous coronary intervention (PCI) during the hospitalization. They also underwent coronary artery bypass grafting (CABG) if they needed the surgery. After 40 days, we evaluated the anterior ST-elevation myocardial infarction (STEMI), mortality, major adverse cardiac events (MACE), heart failure, and limb ischemia.

The VWF level was significantly higher in diabetic patients (P < 0.0001). Also, the increased VWF levels were significantly more frequent in diabetic patients under CABG than in non-diabetic patients under CABG (P = 0.013). There was a significant relationship between positive MACE and increased VWF levels.

The level of VWF in diabetic patients increases cardiovascular problems. Therefore, it seems that these patients can benefit from VWF-reducing drugs. Clinical research can be promising in this field.

The patient handover process is in fact a valuable and essential part of the care processes in the hospitals. This can be a factor in increasing the quality and effectiveness of medical care. Incorrect and incomplete handover can increase the percentage of errors and cause serious problems for patients. The aim of this study was to identify the handover challenges concerning safety and quality of health services.

A systematic review was conducted according to the Preferred Reporting Item for Systematic Reviews and Meta‑analyses guideline. The key words “challenges of patient handover” or “challenges of patient handoff” were used in combination with the Boolean operators OR and AND. The ProQuest, Ovid, Doaj, Magiran, SID, Scopus, Science Direct, PubMed, and ISI were searched.

A total of 263 articles were extracted, and 20 articles were selected for final review. The results of selected articles indicated that there are various challenges such as communication, noncoordination, nonuse of checklist, poor management, time management, and other things. These studies reported that communication was the main challenge of handover process.

Hospitals try to provide a lot of services to the patients and other customers in a safe and healthy environment. Lack of communication among the incoming and outgoing nurses in handover process is one of the main causes of reduced safety and quality of services and patient dissatisfaction.

The purpose of this study was to identify the dimensions and components of organizational agility based on human resource development to provide a model of organizational agility in the Islamic Azad University of Tehran.

The present study was a mixed type (quantitative and qualitative) and at the same time it was an applied research. In this regard, the statistical population of the study includes all employees of the Islamic Azad University of Tehran in 2015- 17, which was about 6735, and using Morgan table and Cochran's formula and multi-stage cluster sampling method and relative 386 employees of the university as The sample size was considered. Data collection method was based on a researcher-made questionnaire, research literature and semi-structured interviews. And Cronbach's alpha coefficient of research tool was calculated 0.919. After distributing and collecting the questionnaires, reviewing the information and testing the hypotheses was done using structural equation modeling and SPSS, LISREL software.

Finally, the research findings confirmed the five dimensions, strategic, information technology, human, organizational and cultural, as dimensions affecting organizational agility based on human resource development. The results showed that the strategic dimension of the highest average and dimensions of information technology and human, organizational and cultural are in the next ranks. Finally, confirmatory factor analysis showed that the dimensions of organizational agility based on human resource development up to 71.282%, the variance of existing indicators of organizational agility based on human resource development explains.

From the perspective of the studied sample, respectively, dimensions: strategic, information technology, human, organizational and cultural in the scale of measurement (1 to 4) have been important to a large extent and very much in organizational agility based on human resource development.
