Abstract
Background & Aim: Management style in medical care is very important in the guidance and performance of the treatment team. This is effective in improving the quality and reducing the treatment time and increasing the productivity of organizations. Using different management styles in organizations will lead to different results in employee performance and organizational productivity. The present study was conducted to determine the relationship between management styles and organizational productivity in the Children's Medical Center of Tehran University of Medical Sciences.
Methods & Materials: This study is predictive correlational in nature. It was conducted on 112 nurses and managers working in the treatment department who were selected based on the random sampling method from. The data were analyzed through conducting ANOVA, t-test, Pearson correlation, and linear regression analysis in SPSS version 16.
Results: The mean score of applying authoritarian style was 4.54, consultative style 5.54, collaborative style 5.55, relational style 5.64 and transformational style 5.59. There was a statistically significant and direct relationship between management style and organizational productivity (p<0.05), (r=0.760). The determination coefficient of linear regression modeling was used to predict the changes in organizational productivity based on the management style indicated that 87.2% of the changes in organizational productivity was explained under the influence of independent variables.
Conclusion: Due to the direct relationship between the use of management styles and organizational productivity, it is not possible to use one style in organizations and the use of different styles in different departments will improve the productivity of the organization.

Abstract
The main objective of this study is to identify and rank foreign investment risk factors and determine their impact on attracting foreign investment in the upstream oil industries. In terms of nature and method, it is descriptive and, in terms of relationships, it is inferential and correlational. The statistical population of the research includes managers and experts in the upstream oil industries, and the sample size was estimated to be 103 people using random sampling. The collected data was analyzed using SPSS, Expert Choice, and Smart PLS software. The results showed that according to the experts in the statistical population, economic risk is the most important factor in foreign investment. Also, in the structural equation modeling method, the correlation between foreign investment risk and attraction factors was significant, with political risk having the greatest impact on foreign investment risk, followed by economic and financial risks and 87.4% of the changes in foreign investment attraction factors could be predicted by foreign investment risk, and the overall fit of the proposed model showed a GOF value of 0.447, indicating a high fit of the research model.

Abstract
As the chain stores grow, crop cooperatives are in danger of being destroyed In this study, strategies for increasing the efficiency of crop cooperatives in one of the northern provinces of Iran are studied. A knapsack problem mathematical model was presented, and then The fuzzy analytic hierarchy process (FAHP) method calculated the desirability (weights) of the identified criteria. Field survey, structured interview,status analysis questionnaire,intra-system strengths and weaknesses, opportunities and threats (SWOT) were evaluated. After analyzing the results of the assessments in the 10 General Productivity Indicator Criteria, 3 Specific Indicator Criteria and 7 Criteria Indicates that there is a deep weakness in the co-operative system and reveals the need for a fundamental change.Therefore, according to the results obtained in this study Criterion (Member Investment -Training-5S-Productivity and Problem Solving-Customer Orientation) made the most investment. The most important point in this issue is limited financial resources .For this reason, considering the utility of the criteria with the expert opinion and the current status of each cooperative in each criterion are two crucial factors. Finally, the strategic goals of the research, using the SWOT matrix analysis, are based on the results of the interviews all cooperatives form of success packages and executive policies.

Abstract
Real-world decision makers are faced with different aspects of the world, and each of the types of hard and soft operations research methods have advantages for responding to certain aspects. Based on this, it can be claimed that by using two or more combined methods, more levels and dimensions of a problematic situation can be investigated and the results are definitely more reliable. The main goal of this research is to solve the problems of electricity shortage caused by cryptocurrency mining in Iran by combining three methods: Strategic choice Approach(SCA), Strategic Option Development and Analysis(SODA), Critical Systems Heuristics(CSH), while examining more detailed levels and dimensions of the problem, solutions or decisions should be adopted to be more reliable and more effective.The combination method is such that SCA is placed as the basis and platform of the research method, In the fourth and eighth steps of sca, soda and csh methods have been used, respectively. The results of this research show wider levels and dimensions of the problems and problems of electricity shortages caused by cryptocurrency mining and lead to the important point that the advantages and benefits of digital currencies should not be ignored due to electricity shortages.
