In this study, the data were extracted from the Rahavard Novin 3 software and then classified by Excel software, and after calculating the variables, finally, through Eviews10 software, the multivariable regression model and panel data was used to test the hypotheses. The results showed that there is significant negative relationship between monetary policies and banks' risk-taking with in 95% confidence level.

This paper examines the credit risk in the Iranian banks during 2008 to 2018 through the Z-score (Accounting based data) and the KMV-Merton (Market based information) models. In the Merton model, equity is equal to call option on underlying value of the bank’s asset. The market value of assets is estimated by share price. The value of assets is then compared to the value of liabilities. Therefore, default when occurs that the market value of assets is less than the book value of debts. so, value of equity becomes negative. In the Z-score model, Return on Assets and Equity to Assets as the numerator and standard deviation of ROA as the denominator are applied. If the mentioned ratios of numerator increase and the denominator decrease, the probability of default decline. As well as, Independent variables are divided into five groups: leverage, management efficiency, profitability quality, financial health, and liquidity. As a result, capital adequacy and profitability have a greater impact on both models. Also, the ANOVA table proves the validity of two models. The value of ROC test in both models is above average (0.5) which are efficient and their efficiency is 99.48% and 92.68%, respectively. Also, in terms of Voung’s test, the KMV is more efficient than the Z-score.

Basically, the progressing society without the presence and existence of specialized work resources with strong tendencies towards ethics and professional principles in the work environment will not be able to achieve its lofty goals and experience development and growth in various economic, political and cultural sectors. Based on this, the current research aims to provide a model of professionalism in the system Iran administration was done. The current research is a qualitative research method. Research in terms of the result of the component It is developmental-applied research that the statistical population of this research is 25 elite people identified in the University of Medical Sciences They were from Shiraz, who were interviewed who had at least 10 years of experience and had a master's degree and a doctorate and the snowball sampling continued until the opinions of these experts reached the point of theoretical saturation and direction Conducting research after designing the general questions and formulating the interview process, conducting in-depth interviews with experts became. The data collected in this research were combined using thematic analysis technique. To review the validity of the research findings was presented to the participants and the text of the theory was studied by them and their points of view were applied at the end of this research, it was studied and reviewed by the professors, and some points were made to modify or change the final theory became. Reliability of data by showing the path of researchers' decisions and also placing all the raw data of the analysis done, the codes, categories, the process of studying the primary goals and questions were given to the academic professors and the desired corrections applied. In order to analyze the data, schematic analysis and data base theory were used. In the presented model, and social accountability as causal factors, organizational conditions as background factors, requirements and necessity environmental factors as intervening factors. In addition, with strategies such as creating open doors for dialogue Knowledge and convergence of actions with professionalism can lead to consequences such as social, financial and behavioral functional results Clients and employees found hands.

This work serves to propose a national electronic health system based on the Big Data approach. First of all, we assessed the practice of health information systems (HIS) in Morocco and their obstacles. We performed a survey that was founded on 24 questions to specify the necessary details on this topic. This study shows that there is a primary need for the establishment of an HIS that facilitates the control, analysis, and management of health data in Morocco. For this reason, we have proposed the implementation of the Moroccan Health Data Bank (MHDB). This system will be based on powerful big data technologies that save, manage, and process health data with greater efficiency. The information present in this proposed system can provide the necessary resources for several actors to exploit this wealth, which is embodied in this massive data. We have developed a general description of the MHDB, its components, its conceptual architecture, and an example of a use case.
