The present study attempts to merge studies and their conclusions on the relationship between religion and happiness using meta-analysis and systematic review methods. Therefore, the articles published in scientific research journals and university theses related to the subject of the study that met other inclusion criteria were identified and included in the analysis. After screening 54 works, and applying exclusion criteria, 14 studies were included in the final analysis. The findings showed the heterogeneity of the effect size and lack of publication bias in the studied studies. Then, the random effect size coefficient was evaluated using the second edition of the CMA software, considering the heterogeneity of the studies and the mediating role of the four variables. According to the findings the size of the combined effect for the relationship between religion and happiness is 0.311, which is considered average according to Cohen's interpretation system. Also, "the time frame of research ", " the place of study", "statistical population", "researchers' field of study ", were mediating variables and the effect size coefficient for their classes was calculated as follows: for studies before and after 2016, it was 0.455 and 0.342, respectively. Also, the coefficient of combined effect was 0.415 for studies conducted in the central regions of Iran and 0.315 for other regions. Also, the combined effect size coefficient of studies in the field of sociology was lower than other fields. This difference is consistent with the theoretical expectations. The results suggested that religion, has a distinct effect on happiness by moderating the above four variables. Finally, driven by the results of this study, some strategies are presented to improve this relationship.

Today, the advancement of technology and means of mass communication has caused the transition of society from traditional to modern, from simplicity to complexity and from one-dimensional to multi-dimensional. Coinciding with these changes and transformations in society, crimes and delinquencies have also become numerous, complex, diverse and widespread, among which we can mention registered crimes. Therefore, this article tries to study registered crimes in the criminal policy of two countries, Iran and Russia, emphasizing the registered crime of forgery and fraud. The question raised in this article is, what is the approach of the criminal policy of Iran and Russia in the field of registered crimes and what points of commonality or difference can be observed between these two countries? The findings show that in the criminal policy of Russia, the two principles of "prevention of registered crimes" and the consideration of the "democratic principle" have been included in their laws more than in Iran, while in the criminal policy of Iran, the subjective aspect and the element Guilt in recorded crimes and lack of attention to the structure of the crime is more pronounced than its nature.

The importance of human resource risk in organizations and industries has greatly increased and even some scholars refer to it as a key responsibility for any professional in the field of human resources. Human resource risks have wide dimensions because they bring significant opportunities and threats to the organization. Therefore, the purpose of this research is to investigate the risk situation of human resources among employees of Tehran municipality. The statistical population of the research is 300 people of Tehran municipality employees (central municipality) from whom 170 people were selected using the Karjesi-Morgan table by available random sampling. The library and field data collection method and the data collection tool in this research is a standard questionnaire. Ernst and Young (2008) standard 33-question questionnaire was used for measurement. The reliability of the questionnaire was confirmed through Cronbach's alpha. In order to test the research hypotheses, a one-sample t-test was used using SPSS22 software. The findings of the research showed that all hypotheses have been confirmed, in other words, the situation of human resource risk and strategic risk components, operational risk, compliance risk, and financial risk in Tehran municipality is different from the desired situation. Human resource risk and components of strategic risk, operational risk, and compliance risk are in an unfavorable situation, and financial risk is in a relatively favorable situation.

In today’s world, using the statistical modeling process, natural phenomena can be used to analyze and predict the events under study. ‎ Many hydrological modeling methods do not make the best use of available information because hydrological models show a wide range of environmental processes that complex the model‎‏. ‎‎‎‎In particular, when predicting, parameters affect the performance of statistical models. In many risk assessment issues, the presence of uncertainty in the parameters leads to uncertainty in predicting the model. Global sensitivity analysis is a tool used to show uncertainty and is used in decision making, risk assessment, model simplifcation and so on. Minkowski distance sensitivity analysis and regional sensitivity analysis are two broad methods that can work with a given sample set of model input-output pair. One signifcant difference between them is that minkowski distance sensitivity analysis analyzes output distributions conditional on input values (forward), while regional sensitivity analysis analyzes input distributions conditional on output values (reverse). In this dissertation, we study the relationship between these two approaches and show that regional sensitivity analysis (reverse), when focusing on probability density functions of input, converges towards minkowski distance sensitivity analysis (forward) as the number of classes for conditioning model outputs in the reverse method increases. Similar to the existing general form of forward sensitivity indices, we derive a general form of the reverse sensitivity indices and provide the corresponding reverse given-data method. Finally, the sensitivity analysis of a water storage design with high dimensions of the model outputs is performed.

The nature of marketing, customer acquisition, and commercialization of academic technology in society through the conversion of knowledge and research into innovation and the production of goods and the provision of services requires that this be done through close interaction and communication between academia and society. The purpose of this study is to provide a framework for explaining the factors affecting marketing, customer acquisition and commercialization of educational technology of University of Mazandaran and the sale of its educational services to the community. For this purpose, after reviewing the relevant thematic literature and extracting the main and sub-variables, using the opinions of 12 experts to evaluate, localize and determine and explain the variables extracted by the Fuzzy Saaty Delphi technique and determine the structural relationships between them using DEMATEL technique. Findings show that among the 21 selected localized variables related to marketing and customer acquisition of educational technology in the form of four main variables (Hardware, Software, Brainware and Organizationware), book variables and their contents, and teaching skills were as the most effective casual varriables, and the variables of start-ups in Incubators, Technology Transfer Office, and student education site in industry, have been the most effective dependend variables. Finally, in order to succeed in marketing and attracting the demand of educational technology customers in University of Mazandaran, while considering all varriables, it is requiring to attend the casual varriables on starting and supporting Entrepreneurship and Innovation Centers, Technology Transfer Office,... even at the International level suitable for different scientific disciplines.

The incorporation of plant residues into soil is a recommended management practice for maintaining or increasing the level of soil organic matter. Although, its effect may be controlled by the soil type, climate and the initial quality of the plant residues. On the other hand, climate on a global scale is changing and the increase of drought stress is predicted in a large scale. As a result of these changes, all soil processes that are related to soil moisture and temperature, including mineralization of nutrients are being affected. This study was conducted to investigate the interactive effects of drought stress and plant residues quality on N mineralization in soils treated with different plant residues.
For this purpose, four types of plant residues including alfalfa, clover, corn and wheat shoots were collected. Plant residues-treated soils along with a control (without plant residue application) were incubated under three soil moisture levels 25, 35 and 55% of water holding capacity at 25৹C for 150 days. At the end of incubation period, net nitrification, net ammonification, net nitrogen mineralization and net production of soluble organic nitrogen were measured.
The results indicated that the maximum amount of net nitrification (282.33 mg NO3- kg-1), net ammonification (52.11 mg NH4 kg-1), net nitrogen mineralization (334.44 mg NO3-㑾 kg-1) and net changes of soluble organic nitrogen (141.43 mg N kg-1) were observed in the alfalfa-treated soils. The measured indices were significantly increased as the level of soil water during the incubation increased. Net nitrification (r=0.798***), net nitrogen mineralization (r=0.816***) and net changes of soluble organic nitrogen (r=0.803***) had a positive and significant correlation with nitrogen concentration of the plant residues. Negative significant correlations were observed between the measured N transformation indices and lignin content (r= -0.589***, r= -0.605*** and r= -0.612***) and ratios of C/N (r= -0.418***, r= -0.410*** and r= -0.424***) and LG/N (r= -0.650***, r= -0.655*** and r= -0.657***), respectively. Net ammonification did not significantly correlated with net nitrification (r=-0.007), net nitrogen mineralization (r=0.051) and net changes of soluble organic nitrogen (r=0.048). Under drought stress conditions, net nitrification (r=.998***) was more strongly correlated with net nitrogen mineralization than net ammonification (r=0.051).
In conclusion, the effect of drought stress on the N transformation indices were not similarly observed among the plant residue-treated soils. The soils treated with plant residues with greater N content (alfalfa and clover) showed to be more negatively affected by the drought stress compared to those treatments contained less initial N or greater C:N or lignin:N ratios (corn and wheat).

There is a growing need for dynamic time history analysis and the absence of proper records in different areas has necessitatedthe production of artificiallaccelerograms compatible with the whole plan. This study presents a new approachbased on wavelet packet transform and artificial intelligence techniques to produce artificial earthquake accelerograms compatible with the whole plan. This approachtakes into account the magnitude and the distance from the fault. The study of neural networks and fuzzy wavelet packet analysis has been used to achieve the desired goal. To do so, first earthquake accelerograms have been collected according to specific site conditions, earthquake magnitude and distance from origin.Then all records have been gatehered for training with fuzzy neural network. Attenuation spectra have been developed on the basis of information in the area using nonlinear regression. Then using fuzzy neural networks, the relationship between earthquake records and the devloped spectra from each record is calculated. In this satge, using wavelet packet analysis, mapping acceleration are analyzed and converted intoaccelerograms (wavelet coefficients)

Congenital absence of the pericardium is a rare condition. The most common form is complete absence of the left pericardium and asymptomatic patients are discovered during cardiac surgery for an unrelated condition and symptomatic patients may experience chest pain or dyspnea. Our patient, a 37 year-old female presented with dyspnea and during echocardiography with positional changing maneuver, we diagnosed the patient to have complete absence of the left pericardium that confirmed with CT scan. Echocardiography with positional changing maneuver can be diagnostic helpful tool for diagnosis of congenital complete absence of the left pericardium.
