The present study was conducted with the general aim of designing and explaining the optimal scenario for the development of triathlon in Iran.

This descriptive-survey type of research has been conducted in a mixed sequential exploratory (qualitative-quantitative) and field study. The statistical population of the research consists of professors of sports management, triathlon federation managers and provincial triathlon boards. The sample size was determined in the qualitative part until information saturation, and in the quantitative part, the sample size (73 people) was determined according to Cochran's table. The research tool in the qualitative part included structured interviews, and in the quantitative part, a questionnaire was obtained from the qualitative part. The form and content validity of the questionnaire was confirmed by professors and sports management experts, and factor analysis was used for its structural validity. The reliability of the questionnaire was also confirmed in a preliminary study on 30 community members and Cronbach's alpha calculation. Exploratory factor analysis was used to analyze the data, and Friedman's test was used to prioritize the identified drivers with the help of SPSS version 23 software.

The model of drivers for the development of triathlon sport in Iran consists of 9 factors of transformation of management processes, media attention, talent search process, popularization of triathlon sport, equipment and infrastructure, human power, economic and political factors, structural factors and finally the processes of winning championships. Is.

a model of feasible, probable and desirable scenarios for the development of the country's trout was developed and presented, which can serve as a good beacon for the officials of this federation and provincial delegations.

Due to increasing population and increasing demand for food, chemical fertilizers as a tool for the desire for maximum production per unit area, have been used indiscriminately, which has caused irreparable damage to the body of the environment. On the other hand, today is the global approach to organic farming. One of the ways to increase plant resistance to environmental stress is to increase the level of substrates of antioxidant enzymes and intracellular antioxidants such as ascorbic acid. This experiment is a split factorial In the form of a randomized complete block design with three replications and in two cropping years 2018-2019 in Ghamsar village located in Shahreri city. In this experiment, drought stress as the main factor in three levels: 40-170-100 mm evaporation from the evaporation pan of class A and biofertilizer including growth-promoting bacteria (azospirillium) and mycorrhiza fungus in four levels including: a) no consumption b ) Seed of growth-promoting bacterium (Azospirillium) c) Consumption of mycorrhizal fungus in the form of seed d) Concomitant use of growth-promoting bacterium Azospirillium with mycorrhizal fungus in the form of seed and ascorbic acid in two levels of foliar application, including a) no ascorbic acid and B) Application of ascorbic acid (two days after irrigation treatment) was considered as a factorial as a sub-factor.

The role of performance appraisal in promoting organizational productivity and monitoring the use of organizational resources is important and each organization should use an appropriate evaluation model to advance its goals and policies. The present study aimed to design and present a suitable model for evaluating performance in this field by considering the legal missions and duties of the country's sports delegations. For this purpose, using a researcher-made questionnaire whose validity was confirmed by 12 senior sports managers of the country and its reliability was confirmed by Cronbach's alpha coefficient of (0.92 ) then sent through 51 sports federations and 31 provincial sports and youth departments to all sports delegations in the country that were designated as a statistical population . In this study, to analyze the data, test the hypotheses and in general, to generalize the results from sample to statistical population, Kolmogorov-Smirnov, T-sample, Friedman, structural equation modeling and PLS Smart and Spss software were used. .Based on the findings of the exploratory factor analysis of this study, 27 items have priority as performance evaluation indicators that sports delegations should will evaluate in the 7 factors or functional areas; Development and public, financial and resources, training, talent identification, competitions and events, camps and deployments as well as legal so it is recommended that delegations in all dimensions Perform functionally continuously.

Sampling methods were targeted and theoretical saturation index and communication software were used for online interviewed with 18 experts and experts. The Delphi technique was used in three stages for Validity of qualitative section, so that the findings were presented in three stages for participant and their point of view were applied. To confirm Reliability, the retest method was used and the results showed that the relationship between the percentages of agreement within the subject is equal to 0.91, which is appropriate. After identifying the factors affecting the development of educational sports, the factors in the matrix table were compiled as a questionnaire and provided to the research sample and they were asked to complete the questionnaires based on the ISM method. To determine the causal relationships of the indicators, the structural-interpretive modeling method was used and Micmac software was used to draw the model. Finally, 7 major categories including re-needs assessment, strategy formulation, two-way communication, correction of virtual education processes, operational plans, use of global models and factors affecting development were identified as indicators of educational sports development model in education during health crises.

Summary :

The research method in this work was a mixed quantity and quality one. In the qualitative part, the focus group in the form of the steering council express their views on how the strategies interact and causeand-effect relationships with each other in the form of interpretive structural modeling (ISM) symbols in their interactive strategy matrix (SSIM). These symbols are quantified in the initial access matrix, and through these hierarchical levels of strategies in the quadruple table, the final matrix map is identified, and according to the cause-and-effect relationships between them, the strategy map of the National Football Academy by the model method is presented. The levels formed from the fourth to the first level are the growth and learning perspective, customer-oriented internal processes perspective, stakeholder perspective, and financial perspective. These scenes correspond to the views of the balanced scorecard.

 The purpose of this work was to design a hierarchical design of the strategy map of the National Football Academy using the interpretive structural modeling (ISM). One of the distinguishing features of the Balanced Scorecard from the other methods is that it creates the cause-and-effect relationships in the strategy map between the strategies of each perspective. If the cause-and-effect relationships between the strategies are properly identified in the strategy map, a path is provided to the organization that describes and demonstrates how the strategies are implemented. Of course, despite the importance of determining the cause-and-effect relationships, a systematic method is required to determine these relationships, which is not mentioned in most articles related to the strategy map. In the recent years, one of the main problems of the country's football has been the excessive attention to the adult football and the lack of attention to the basic football. The missing link of the national championship sport is also an integrated and purposeful talent identification system according to the contents of the plan of the national sports community and other unrelated research works.

Methodology and Approach:  

The research method was a mixed quantity and quality one. In the qualitative part, the focus group in the form of the steering council express their views on how the strategies interact and cause-and-effect relationships with each other in the form of ISM symbols in their interactive strategy matrix (SSIM). The statistical population of this research work, which was equal to the statistical sample of the research work, was the same members of the steering council of the National Football Academy (N = 10).

These symbols were quantified in the initial access matrix, and through these hierarchical levels of strategies in the quadruple table, the final matrix map was identified, and according to the cause-and-effect relationships between them, the strategy map of the National Football Academy by the model method. The interpretive structural modeling (ISM) was drawn in 4 levels. In this map, the strategies related to each level were listed. In the first level, the financial strategy 2 strategies and in the second level or stakeholder perspective of one strategy, in the third level or the internal process strategy 4 strategies, and in the fourth level, the growth and learning perspective 3 strategies. Balanced Scorecard Scenes provided by Norton and Kaplan include Scenes of Growth and Learning, Internal Process, Customer, and Finance. The rationale for distinguishing a balanced score from other methods is that, firstly, there is a cause-andeffect relationship between the scenery and the strategies contained in the scenery, and secondly, these scenarios are at a hierarchical level. The method of interpretive structural analysis helped the researchers to determine their causal relationships by analyzing the relationship between two strategies. In general, the researchers were able to determine the causal relationship between all strategies in a ten in ten matrix, and extract and determine the levels of strategies. The concepts of strategies at different levels showed that the logic of BSC also governed the results of this work. The titles of the levels formed from the fourth to the first level are the growth and learning perspective, customer-oriented internal processes perspective, stakeholder perspective, and financial perspective. These scenes correspond to the views of the balanced scorecard.

Soil, as one of the key systems of the earth, provides goods, services and resources for humankind. So, if it is being damaged, the foundation of an important part of human needs will be collapsed. The purpose of this study is to investigate the amount of pollutants and pollutant sources in the surface soils of Qal'ehno and part of Kahrizak district villages in south of Tehran.

The research has been done in autumn 2017 through an analytical-descriptive method. The data used in the analysis are based on the measurement of contaminants in the samples. 144 sample points were selected by grid method and soil samples were taken and measured, then the results were entered in the GIS. We used IDW method for interpolating the point and introducing zoning maps. The analysis is based on separated and overlapped maps of the spatial distribution of pollutants in accordance with quantitative data and the conditions of the contamination sources.

Data analysis and zoning maps showed that the concentration of barium, cobalt, chromium, copper, nickel, lead, uranium and zinc in the region soils was higher than the permitted limits and the concentration range of the pollutants studied (in mg / kg) and the concentration area of each of them was as follows: lead from 6 to 168 and the highest in the northeast, cadmium from 0.6 to 2 and the highest in the north-west, arsenic ranges from 0.6 to 13.4 and the highest in the northeast, nitrate from 80 to 700 with the highest in the south-west, organic carbon from 0.6 to 3 and maximum concentration in the north-west, and finally, TPHs with an average of 0.051 and concentration of the highest densities in the center of the region.

Although soil contamination is high in the whole area, the severity of density is generally higher in those parts that use more untreated wastewater in irrigation. The permeability channels through which sewage is passed, the use of untreated wastewater in irrigation the oil refining industry and the storage and distribution of oil products have affected soil contamination.

The purpose of ‎this study is to analyze the status of urban parks enjoyment and accessibility in Eslamshahr, a city ‎with a population of more than 540000 located in 12 Km southwest from Tehran. The research ‎method is Comprative evaluation and we use descriptive statistics indexes such as per capita and ‎covered land ratio, and accessibility measures based on minimum distance to the nearest park, and ‎the park access areas. Finding showed that both per capita park lands (2.2 m2) and ratio of park ‎lands are low (2.2 m2 and 1.3% respectively). There are also large disparities in spatial distribution ‎of parks as more than 42% of the city's area, in which more than 29.5% of the population reside in, ‎is not within parks access areas. This is while in the southern part of the city, access area of 10 ‎parks are overlapped. In term of accessibility, district 4th of Eslamshahr municipality in south, has a ‎more appropriate condition, so that half of its inhabitants reside in a maximum distance of 60 m ‎from nearest park. In contrast, district 5th has only one park and the distance between most ‎residents and the park is high. In order to move towards environmental justice, it is necessary to ‎allocate more land to parks and construct and develop parks, especially in the central part and in ‎the parts with no access to existing parks.

Awareness of the existence of the relationship between organization culture and job motivation with job satisfaction of librarians in Libraries of Islamic Azad University in Hamadan and Markazi Provinces is the main purpose.

Among the librarians of Markazi Province, the highest average relates to the nature of the job.  Among 6 components of job satisfaction among the librarians of affiliated libraries the highest average belongs to direct responsible. Between the variables of the organizational culture and job motivation from the perspective of librarians of academic libraries of Hamadan Province average of organizational culture is more than job motivation, but the organizational culture of librarians of academic libraries of Markazi Province    job motivation.

There was a positive and significant relationship between organizational culture and job motivation with job satisfaction, as well as with the experience of librarians in related libraries. There is no meaningful relationship between age and education variables with job satisfaction from librarians' perceptions of affiliated libraries.

This study investigates hydrocarbons and heavy metals pollution in air, soils, and plants in Baghershar and its peripheral located in about 4 km south of Tehran by using an analytical descriptive method. As area study has a favorable situation near Tehran megacity and has had proper geographical conditions, many giant plants including Tehran oil refinery and its relatives and so many other pollutant plants and workshops have been located here since the 1960s. The analysis is based on sample measurements of 12 samples of air, 24 samples of soils and 24 samples of perennial plants. The finding shows that the region is polluted by hydrocarbons and heavy metals origin from the plants and their relative transportations. The high density of the contaminants in the air could be harmful to human life and so could leave harmful effects on soils and plants. High values of hydrocarbons and zinc in samples show that the soils in the region are polluted too. Although the values of nickel and vanadium were lower than the standard level, but the high levels of contaminants in the soils could be a risk for plants and water resources. Measurement of sample plants indicates that hydrocarbon and zinc contaminants had a higher density than others and the higher values obtained from Baghershar urban areas. Although the concentration of the heavy metals in plants are far from crisis level, but as the values are high, its expect them to increase in the future and cause many harmful effects. Finding also shows that pollution in the area study has being affected by the oil refinery and relative activities in storing, distributing and transporting of oil products.

In this paper, the specimens woven by the same weaver with identical materials but with four different types of knots, i.e., symmetrical, asymmetrical, jufti and U knots, which their details are given in a previous paper by these authors, are used. The effect of these knots on such physical properties as width of the weave, length of the motifs, length of yarn in a knot and the carpet weight are measured. The woven samples are produced in two different methods. Resulrs show that the width of jufti and U knot samples were reduced after cutting off the loom, while the change in the width of the other two is little. The change in the length of motifs depends on the change in the carpet length, i.e., in samples with change in carpet length, the motifs length change as well and in cases that there are little change or no change in the carpet length, accordingly no change or little change is observed in the motifs. In the meantime, by subjective investigation of shapes of motifs in the four different knots, the change in their details and the sharpness of the lines and curves in them are studied. The results of computation of the ratio of the wool yarn to cotton yarn demonstrates that in symmetric and asymmetric samples more than two third of the carpet weight is built up by wool yarns, so that it is predicted that they have better mechanical function compared with other knots. Jufti sample has the lowest ratio of wool to cotton yarn, so it would show the worst mechanical performance.

Symmetric and asymmetric knots, as two original knots, possess different physical and mechanical properties that influence the function of a carpet. Jufti and U knots give different properties to the carpet compared to the original ones. If they were used to produce specific properties, they would enhance the carpet's quality. However, nowadays their applications are considered as methods that diminishes the quality of carpets. As these properties have significant influence on the carpets, some attention is paid to them in different papers and textbooks. Carpet samples are woven with each knot type and identical materials by a weaver. Then the effect of various kinds of knots measured on the carpet length, carpet thickness and pile height. Samples are woven in two different methods. The first one is a method in which the number of beating the comb is controlled; i.e., after each row of knots only and exactly two comb beats are applied to the row of knots. In the second method, the dimensions of samples were controlled and it is tried to weave the carpet with the dimensions designed; i.e., the number of times the comb is beating down the row of knots varies according to the weaving progress. In jufti and U knot samples, the number of beating times inevitably reduced to one, while in symmetric and asymmetric samples it increased to five to six times to obtain the designed dimensions. Results show that symmetric and asymmetric knots lead to an increase in the carpet length, whereas the other two knot types end in a decrease in the carpet length. To reach the designed length it is necessary to change the number of beating or to use different materials with suitable yarn counts. The thickness of the foundation of carpet is also influenced by the knot type; i.e., if the number of comb beating increases the foundation thickness increases as well, but if the number of comb beating remains constant there will be identical foundation thickness in carpets woven with different types of knots.

Evaluating views and the conditions of central libraries was greatly helpful in attaining a coordinate management in the book and magazine purchase in some central libraries of Islamic Azad University to create an on-line purchase network.
The enterprise is also indebted to the questionnaires that produced effective information in network efficiency and its acceptance.
The survey suggests that 72.5% of the central libraries have between 1 to 5 people of manpower and the rest of them have more than 6 people of manpower. Lots of financial security is appropriated for annual purchase of resources.
In addition, there exist computer equipment 100% and printers (88.7%).Of course, the availability of other equipment is not equal in all universities. The percentage of 73.8 exists between the managers’ degrees and their interest in establishing the liberty studies network, but the relation between the managers’ degrees and establishing the purchase network was not confirmed. It was also confirmed that the network had great impaction handling the book purchase and e-notes communications and finally in optimizing the library space .With respect to the space scarcity of 60% the management of book purchase is deemed necessary.
In general, the minor factors connected to the network were detected and analyzed, and the major elements related to the research hypotheses e.g. equipment, manpower, budget, and the space were in coordination with our positive views. Therefore, the creation of a purchase network is effective in the management of resources, economic use of the equipment and its economy, the decrease of manpower, budget management, and the prevention of unnecessary purchase that increases the number of stock books.

The purpose of this research is to find out the views of the Islamic Azad University library employees from the Region 5 about the importance of information technology and how influential information technology is regarding their job performances and improvement? Hence, 65 library employees from different ranks were asked and their responses have been used in this project. The method used is survey-descriptive and a questionnaire was used to gather needed data. In this research, initially the level of information technology used by the librarians was investigated, and then its impact on the library employee's job performance and their improvements were studied. In this study, variety of factors such as job performance improvement, independence, freedom, responsibility, satisfaction, decisiveness, innovation, self control, and etc. have been used to eventually come up with hypothesis and make up the basic questions discussed in this project. According to the hypothesis using information technology can cause obvious improvement at the job performance level of the library employees of the Islamic Azad University Region 5. Findings show that Region 5 libraries have at least between 1-5 employees, 64.6% of them studied Librarianship at college and the number of computer per capita is 69.2%. 25% of these employees have indicated the usage of software such as intranet, Excel and Word and etc. whereas the number of those using practical software and different computer sites goes up to 50% of our research population. Current library activities such as cataloging, issuing membership cards and graphical usage still show more increase of about 70% of the employees. Moreover, the libraries provide excellent facilities such as information banks, either continues or discontinues, fax, telefax, printers and so on. Data analysis verified number of influential factors on job performance improvement such as decrease in number of job related errors, job satisfaction and faster service being provided by these employees. Other factors also related to information technology and its positive impact on these employees were observed and verified: including increase in job satisfaction, more willingness to make job related decisions and accepting more responsibilities. After all, considering the data and their analysis, the hypothesis in this study was confirmed.
