The purpose of this study was to evaluate the performance of safflower under the influence of humic acid and zinc chelate in field conditions. The experiment was carried out in a factorial form in the form of randomized complete blocks in a farm in Saqez city in 2019. The results showed that the effect of humic acid treatment was significant at the 5% probability level on plant height and on the number of sub-branches at the 5% probability level. The effect of zinc chelate and the interaction of treatments on both traits were significant at the 1% probability level. The use of all three foliar treatments (humic acid zinc chelate and the interaction of treatments) had a significant effect on the number of seeds per plant. Comparison of averages showed. The highest number of seeds per plant in the combined treatment of 1 mg/liter of zinc chelate and 400 mg/liter of humic acid (125/33) as well as the treatment of 2 mg/liter of zinc chelate (123/25) and the lowest number in There was a combined treatment of 100 mg/l of humic acid and 2 mg/l of zinc chelate. The results showed that zinc chelate treatment and the combined treatment of zinc chelate and humic acid had a significant effect on the number of leaves in safflower plant, but humic acid treatment did not have a significant effect on this trait. C The results of the present study showed that the amount of linoleic acid increased with the addition of humic acid and zinc chelate, but the amount of oleic acid decreased.

The hospital information system is an electronic tool that collects, classifies, stores and retrieves the financial, administrative and clinical information of patients using computer capabilities and provides them to decision makers at any place and time. The present study was conducted with the aim of evaluating the acceptance of the hospital information system from the point of view of the users of teaching hospitals of Ahvaz University of Medical Sciences.

The problem of allocating space to academic needs is one of the complex optimization issues that distributes a limited set of educational and research needs to a set of resources with a set of constraints. Due to the complexity of this problem, several techniques based on innovative methods have been proposed. In this paper, a mathematical model of integer programming is presented to formulate this problem.

To solve the model, the gradient descent method is used and its parameters are adjusted. To evaluate the proposed model and solution, the data and facilities of one of the fledgling faculties at Allameh Tabatabai University in Tehran are tested. There are 11 requirements and 18 allocable spaces in this faculty and therefore there are 198 binary decision variables, in the model. In experiments, several scenarios are created and the results of each scenario are compared.

The proposed model and solution is a general method and can be used for other faculties and universities that face space constraints.

Originality/Value:

 In this article, a mathematical model was presented to formulate the problem of allocating space, which is one of the important decision-making issues for organizations and research educational institutions.

Teachers are considered as one of the most important and vital elements of virtual in-service training, and supporting them is one of the basic elements in the virtual training system. Supporting teachers in the virtual learning environment is one of the key factors in the success and development of the virtual training system that if it is not continuously provided, it will lead to a waste of capital and a lack of motivation to stay in the virtual learning environment. Support for teachers has different areas, among which we can mention instructional support. In virtual in-service teachers training, instructional support has priority over other different areas of support and is more important. Instructional support is one of the main components affecting the effectiveness of virtual training. Dynamic computer-based scaffolding is one form of instructional support that supports learners in a personalized way. The purpose of this research was to investigate the effect of dynamic computer-based scaffolding on the effectiveness of virtual in-service teacher training.

This research was conducted in a quasi-experimental way using a pretest-posttest design with an experimental and a control group. The statistical population of this research consisted of elementary school teachers in the academic year of 1401-1402 who applied to participate in virtual in-service training. A total of 30 elementary school teachers were selected as a sample to participate in the research, who were randomly divided into two groups of 15 people, experimental and control. The tool used in this research was a researcher-made questionnaire for the evaluation of virtual in-service teacher training based on Roderick Sims’s developed model. This model has 11 components including educational objectives, content, design and user interface, interaction, evaluation, support services, outcomes quality, organization, management, educational technology and information and communication technology ethics. The validity of the questionnaire was confirmed by experts. Also, the reliability of the questionnaire was obtained as Cronbach's alpha coefficient of 0.82. The experimental group received dynamic computer-based scaffolding during the virtual in-service training, but the virtual in-service training was presented to the control group in the usual way. Descriptive statistics indices (mean and standard deviation) were used for data analysis, and covariance analysis was used in the inferential statistics section.

The results of the research showed that training through dynamic computer-based scaffolding was of significant impact on the effectiveness of virtual in-service teacher training. Also, dynamic computer-based scaffolding in each of the components of the effectiveness of virtual in-service teacher training, including organization and management, educational technology, educational objectives, content, design and user interface, information and communication technology ethics, interaction with the user interface, evaluation, support services and quality of outcomes had a significant effect.

In virtual in-service training, dynamic computer-based scaffolding can provide the help and guidance needed by teachers and lead to mastery in learning and helps teachers to play an active role in training. Regardless of this, the use of web-based tools and technologies is emphasized in the studies as long as they can facilitate the performance of learners in learning, and have an effect on the effectiveness of education. Therefore, considering the benefits of dynamic computer-based scaffolding, it is suggested that those involved in virtual in-service teacher training include the design and development of dynamic computer-based scaffolding in their work agenda.

In virtual in-service teacher training, instructional support or scaffolding is an essential component of effective training that can be provided in the form of computer-based scaffolding. Personalization of computer-based scaffolding is achieved with dynamic computer-based scaffolding. The purpose of this study is to design and validate a model of dynamic computer-based scaffolding in virtual in-service teacher training. The research method used in this research was mixed method with sequential exploratory design. In qualitative research, the synthesis research method was used and the components of the model were extracted and a concept and process model was designed. Quantitative research was used to validate the model and survey research method and questionnaire were used and the internal validity of the proposed model was confirmed. Dynamic computer-based scaffolding model in virtual in-service teacher training has 8 main components and 47 sub-components. Key components include analysis with 11 subcomponents, design with 16 subcomponents, development with 3 subcomponents, implementation with 3 subcomponents, evaluation with 8 subcomponents, dissermination with 3 subcomponents, process evaluation and revision, and review and revision with 3 subcomponents. Internal validaty findings from experts showed that concept and process model have a high internal validity. Dynamic computer-based scaffolding model in online in-service teacher training can be used to design dynamic and computer-based instructional support and lead to learning and independent performance in the future.

The image is the relationship between the outer world and the inner world of the poet and the artist. An image in poetry is an equation between two phenomena, for example between likeness and likeness, the purpose of which is to prove beauty or proportion. Allusion is one of the rhetorical techniques that is used for the effect of words and is based on analogy and proportion Jami is one of the leaders of Iraqi style poetry who has made significant use of allusion. He uses simile, metaphor, allusion, irony, etc. He has created beautiful images in poetry, especially in ghazal, using allusions. The most prominent allusions of Jami in Ghazal are: Qur'anic allusions and allusions and the story of prophets, historical-story allusions and mythological allusions and allusions. Using descriptive-analytical method, the authors examined Jami's semantic and visual attitude in sonic allusions.To express his thought, Jami has used important mystical concepts such as "unity of existence, manifestation, poverty, annihilation, etc." and also using literary industries such as:"simile, metaphor, ambiguity and irony, etc.".

Determining the position and importance of scientific groups in the operational structure of the university and its important role in improving the quality of educational and research activities of the university's affiliated faculties is one of the important issues for universities. Some universities have provided simple models for classifying scientific group, but there is still no coherent and complete system for ranking scientific groups in universities. The main purpose of this study was to provide a suitable model for ranking scientific groups in universities and higher education centers in the country. In this qualitative research, the methods of qualitative content analysis and semi-structured interviews were used. Qualitative content analysis was done inductively and semi-structured interviews were conducted with research participants on the topic and how to rate and rank categories and subcategories. To analyze the data obtained from semi-structured interviews, interpretive analysis method was used and finally the components of the model and their scores were extracted. Mission, goals, organizational position; training courses and curricula and non-curricula; science Committee; Students; Learning / teaching strategies; educational facilities and equipment; theses and dissertations, seminars, research contracts of chairs and graduates were components of the ranking model of scientific group in Iranian universities and higher education centers.The results of this ranking model can be used for all scientific groups and fields of study. It will also be useful to develop this model in the form of a mechanized system for different uses such as comparing academic departments in universities and leveling faculties.

Like literature, architecture has a bond with symbols, mysteries, metaphors, mystical concepts, socio-cultural mentalities and etc. and like literature is considered one of the most outstanding displays of the culture and thoughts of nations in different periods. In fact, words, elements and idioms in architecture are considered as one of the inspiring, artistic and array making tools for poets and writers. Extracting, studying and assessing buildings that are mentioned in poetry and writings of Persian literature, helps to know the architectural styles of different periods and to illustrate the ambiguous parts of Islamic and Persian history of architecture to a large extent. The period under study in this article is the Timurid period which it's most important characteristic in its architecture, is related to the decoration of its buildings and in this view this period is considered to be one of the most important periods of Islamic architecture. On one hand results of this research are an indicator of the usage of decorations like “Muqarnas, plastering, engraving, calligraphy and inscription, goldsmithing, woodcarving and shamseh” in architecture in Timurid period, and on the other hand are an illustrator of the manner and amount of usage of these decorations in the creation of literary arrays in poetry of this period. This article is prepared using the library and interpretation and analyzation method. Surely literature is one of the most important resources of discovery and extraction of kinds of decoration used in architecture in different periods. and architectural decorations are also considered one of the most beautifying tools in literary texts. So, study of important works of poetry and writing remaining from the Timurid period, especially Jami's poetry is very important in this view.

User interfaces are a crucial factor in ensuring the success of an application. Mobile Educational Applications not only provides the flexibility of learning, but also allows learners to learn at any time and any place. The purpose of this article is to investigate the factors affecting the design of the user interface in mobile educational applications.

The research method used in this research is quantitative content analysis method. The statistical population included scientific documents in EBSCO, Scopus, Springer, ProQuest, Google Scholar, and ScienceDirect databases for the period 2014-2019, using Internet searches with keywords for user interface design, mobile-based education and educational applications were searched. The volume of the research population consisted of 35 documents, which were selected 27 valid documents by targeted sampling method. In order to verify the selected researches, the articles were first categorized in terms of objectives, methodology and results, and their results were compared, and their similarities and differences were studied.

Placing the user in control, reducing the user’s memory load and making the interface consistent are three main rules in user interface design. Among the features of educational user interface design can be mentioned to the development of problem solving skills, fading the degree of scaffolding provided by the interface over time, supporting distributed problem solving, attracting learnerchr('39')s attention, enabling learners to interact with each other to facilitate retrieval of knowledge and supporting of management of cognitive load.

With recent advances in technology, there is now more flexibility to control the interface available to learners. At the same time there has been an increasing emphasis upon more interactive and collaborative approaches to using learning technologies. A mobile-based educational user interface design framework can enhance user performance with respect to cognitive performance and interaction which ensures better user experience.

Unlike classical cryptography, where security is based on computational complexity, quantum cryptography has unconditional security, which is based on physical constraints. So far, the semi-quantum version of many of the problems of secure quantum communication protocols has been proposed. In this study, we examined semi-quantum protocols that allow users to access a secret message directly without distributing the key. An important factor used to analyze the performance of secure quantum direct communication protocols is efficiency. In this study, the proposed semi-quantum secure communication protocol against various quantum attacks has been investigated. In the proposed scheme for decoding the confidential message by the receiver, a sequence of single photons is required, which is first generated by the controller. The proposed protocol has a yield of 50%, which is higher than the previous protocol, which has a yield of 66.6%.

Many of the world's top universities have already decided to hold the next semester with e-teaching. In Iran, too, the forecasts show a red situation for some areas in terms of corona prevalence. Also, several university students live in these areas. In planning the next semester, therefore, more focus should be on e-teaching. According to the instructions of the Ministry of Science, Research and Technology in Iran, education should be implemented in two parts, including e-teaching and face-to-face training. In face-to-face education with the needs of the educational space, students are divided into disciplines so that the implementation of health protocols in the university and educational space is possible. For this purpose, in this research, a mathematical optimization model is presented to allocate semester weeks to students of different disciplines in coronary-living conditions.

In this paper, to determine specific weeks for students of different disciplines during the semester in face-to-face education, a mathematical optimization model is proposed in the form of nonlinear programming with integer variables. In the objective function of the model, the distribution of students in the educational space during consecutive weeks during the semester should be done in such a way that it has the maximum possible dispersion to prevent the spread of coronary heart disease.

This model has been implemented to allocate semester weeks to students of different majors at universities, in general, and its use has brought positive results for decision-makers, particularly at Allameh Tabataba’i University.

The results obtained from the implementation and execution of the model will bring a clear and positive perspective for decision-makers in universities. To continue this research, another optimization model should be designed and implemented for each faculty, taking into account the limitations of each department

Thymes are native plants of Iran and are considered as the most important medicinal plants due to their unique properties. In this study, morphological, ecological and essential oil percentage variation of 15 thyme populations (eight populations of T. kotschyanus, three populations of T. migricus, two populations of T. fedtschenkoi and one population of T. fallax and T. pubescens) from natural habitats of the northwest and west regions of Iran, were studied. For essential oil measurement, the flowering shoots of the populations were harvested during flowering season and the essential oils were extracted using Kelevenjer apparatus by distilled water for three hours. By examining the soil characteristics, climatic parameters and geographical position of the habitats, it was found that despite the geographical proximity, there were significant differences between the locations in which thymes were collected. This, along with genetic differences among the populations, led to a remarkable variation for all measured traits. There was negative correlation between essential oil percentage and inflorescence length. Using principal component analysis, the first three components explained 85% of the total variation. Using cluster analysis, the 15 populations divided into three groups. The populations in the third group had the highest values for most traits followed by the second and the first groups, respectively. According to results, Ghoghjeh population had the highest values for morphological characteristics. There was also a significant difference among the populations in terms of essential oil content. The essential oil percentage of the populations ranged from 0.92 to 2.82%. The highest values of essential oil 2.82%, 1.9% and 1.7% were obtained from Sardasht, Qushchi and Naghadeh populations, respectively. According to the results, the populations of Sardasht from T. fedtschenkoi, Qushchi from T. migricus and Naghadeh from T. kotschyanus had the highest essential oil content, and suggested for cultivation and using in related industries, pharmaceuticals, and improve breeding varieties.

Dog Rose shrub is one of the valuable medicinal plants that, due to the richness of useful compounds in the fruits, has the potential to be used as dietary supplements. The aim of this study was to investigate some morphological and phytochemical traits of 20 Dog Rose genotypes collected from natural habitats of the northwest and west of Iran. Trunk diameter, trunk cross-sectional area, plant height, canopy width, tree size, and volume index were recorded before harvesting. The leaf length, leaf width, leaf fresh weight, fruit length and width, fruit tail length, fruit fresh weight, number of seeds per fruit, fruit flavor, fruit texture, fruit appearance and attractiveness, total phenol, total flavonoids, and antioxidant capacity were measured. The results of the analysis of variance showed that there was a significant difference at the 1% probability level among the samples collected from different locations for all traits. The poor correlation between traits resulted in the first two components of principal component analysis justifying a lower percentage of variation in the data. Cluster analysis using Euclidean Squared Distance and Ward Method showed that the studied genotypes were divided into four groups with different characteristics. The sample of Showt city, which was placed alone in the fourth group and also had the lowest elevation, had the highest value for most of the traits and could be considered in breeding programs.

Anthemis has 39 annual and perennial herbacius species that 15 species of them are from Iran. Iran has a good distribution of this medicinal plant. In this study, the growth characteristics, essential oil percentage and ecological features of five Anthemis species such as: (A. tinctoria), (A. hyalina), (A. wiedemanniana), (A. pseudocotula) and (A. haussknechtii) were evaluated for the first time, in order to better understand the characteristics of them in Kurdistan province. The collection of species was carried out at flowering time and 14 growth traits along with ecological characteristics of the habitat were studied. The results showed that there is variation in growth characteritics and essential oil percentage among the studied species. A. tinctoria and A. hyaline had the highest growth and yield. Essential oil percentage was from 0.02 to 0.15%, most of which was related to A. hyaline (0.15%) and A. setacea (0.08%), respectivly. Cluster analysis divided the species into two groups. According to the results of this study, A. hyaline due to the high growth, organs with contains active ingredient, and high amount of essential oil is superior and can be used in pharmaceutical, food and perfumery industry and breeding programs.

The main goal of this study is the prediction of companies listed in Tehran Stock Exchange using decision tree and logistic regression، which are data mining methods and can help facilitate prediction. Financial ratios are independent variables and healthy and bankrupt companies are dependent variables. Statistical population of the research is information about financial statements of companies listed in Tehran Stock Exchange during 1999 – 2010. No sampling was used in this study; we have two groups of healthy and bankrupt companies. Bankrupt companies group was selected based on article 141 of Commercial law and the healthy group was selected based on profitability criteria. Results suggest that both decision tree and logistic regression methods predict bankruptcy with different accuracy. Area under ROC curve in logistic regression model is more than in decision tree model.

Depression is one of the problems in postmenopausal women with the age of 55 to 65 years. This problem، due to physical disability and injuries which can create، is very important. In 2012، 100 women with depression were enrolled and randomly assigned to two groups (n = 50) of intervention and control. The intervention group participated an 8-week aerobic exercise program (3 sessions per week for an hour)، but the control group did not receive any intervention. The collected data included the Beck Depression Inventory results before and after aerobic exercise. Data analysis was performed using ANOVA test with repeated measures. There was a significant difference in the rate of depression prevalence between the intervention and control groups after 8 weeks (P < 0. 05). The results showed that aerobic exercise increased the muscular strength and self-esteem and decreased depression. It appears that using these exercises could be useful as a complementary therapy in postmenopausal women with depression.

Almost all postmenopausal women will experience depression. Also، most women lack the ability to control and reduce depression، the disorder can lead to physical damage. The aim of this study was to investigate the effects of 8-weeks of Pilates exercise on depression in postmenopausal women in the age of 55 to 65 years. In this experimental study، 40 women with depression referred to psychologists in the year 2012، as a target، selected and randomly divided into two equal groups of intervention and control. The intervention group did Pilates exercise program for 8 weeks (3 sessions per week for one hour); the control group did not any exercise. The Beck’s Depression Inventory used to evaluate the before- and after- exercise status of the participants. Data analysis was performed using ANOVA test. There was a significant difference in the rate of depression in the intervention group compared with baseline and the control group after 8 weeks (P < 0. 05). The Pilates exercises decreased the depression rate significantly. It seems to be useful as a complementary treatment in postmenopausal women with depression.

Neurotransmitters، such as dopamine and serotonin، play an undeniable role in the incidence of mental illnesses. Sports have positive effects on the level of neurotransmitters in nerve cells and the balance in neurological function. They can thus reduce a person''s mental abnormality. In this study، 35 female patients who had been admitted to the psychiatric ward of Khorshid Hospital (Isfahan، Iran) were evaluated. The patients were randomly allocated to experimental and control groups. Although the experimental group initially included 24 subjects، four women were excluded since they were not interested in group sports. They were encouraged to perform individual activities such as stretching. Finally، the experimental and control groups comprised 20 and 15 participants، respectively. After warm up and stretching exercises، the experimental group played volleyball، badminton، or dodgeball in teams of 4-5 every day for two months. However، the control group were only encouraged to perform warm up and stretching. At the end of the 60-day period، Beck Depression Inventory was filled out by physicians based on the statements of patients. According to the patients، both individual and group exercises had positive effects on their mental state. In fact، some patients were discharged after the period of study. Nevertheless، mental health of the control group improved considerably more than the control group. This finding suggests the benefits of group exercise. Regular exercise will promote individuals’ physical and mental health. It reduces the risk of chronic diseases، increases life expectancy and eliminates depression. Proper exercise helps the body to control its nervous system and results in greater confidence and better decision-making under stress. On the other hand، depression and stress are influenced not only by a person’s mental conditions and confidence but also their physical state. Exercise will regulate blood temperature and enhance physical functions under special circumstances. We obviously observed the positive effects of sports، especially team sports، on women''s depressive symptoms.
