Gas to liquid (GTL), is an industry that uses special chemical methods that converts natural gas or other light gaseous hydrocarbons into heavier chain hydrocarbons such as gasoline, gas oil, and other heavier products usually obtained in the crude oil refining process. In this study, the global supply function of GTL industry was investigated. The necessary information was obtained from a valid source from 1987 to 2019 and the autoregressive distributed lag model was used to investigate the impact. The results of estimating the model with dynamic, long-term and error correction models were estimate, and the results show that the interval of logarithm variable of GTL supply has a positive and significant effect on the logarithm of GTL supply in the current period and its coefficient is equal to 0.01 units. The results also show that the first interval of the logarithm of the oil and gas gross production variable with 0.25 units influences the logarithm of GTL supply in the current period and the logarithm of natural gas price with a coefficient of 0.09 units has a positive and significant effect on the logarithm of GTL supply. According to the obtained results, it is suggested to increase the surplus of gas production by improving and reducing wastage in consumption on the one hand and investing in increasing production on the other hand. Also, competitive pricing to encourage investors in the development of this industry should not be overlooked.

Rapid developments in organizational technologies and processes, advancement of knowledge and development of management science in the field of health services on the one hand and increasing the costs of providing and providing care on the other hand have caused strategists and policy makers in the sector. To make the planning, presentation and evaluation processes of health services more effective and efficient by using the various capabilities of e-commerce and information technology. In this regard, the present study has researched health tourism and trade of this type of services in Muslim member countries of the Islamic Conference.

This article is based on the comparative advantage of 50 Muslim countries in the period 1990 to 2017 using the panel data method, and using the dependent variable of health tourism and independent variables including economic size, population size, distance of countries, exchange rate, tax rate, Common language, regional arrangements, the Organization for Economic Co-operation, eight developing Islamic countries, the Gulf Cooperation Council and the Western Maghreb have been examined.

According to the acceptable value of F-Limer statistic and significant value that is less than 0.05 and the results of Haussmann test, the model will fit the panel data using the fixed effects method. The results of the present study indicate that by increasing the effective economic size by one percent, the improvement of health tourism will increase by about 0.1 percent. The obtained negative coefficient of the border distance variable shows the effect of 17% of this variable on the improvement of health tourism.

of the main issues in the developing countries is the correct management of the exchange rate, so that less or more evaluation than the equilibrium exchange rate causes instability and imbalances in macroeconomics, especially in the field of exports and imports, the general level of prices And financial markets. Hence, economic policymakers are seeking solutions that will enable them to steer the exchange rate in the right direction. The most important of these factors is inflation. this study, the effect of inflation targeting policy on exchange rate management in the selected developing countries during the period 2000-2017 by the method of panel data has been investigated. Experimental results showed that the deviation of inflation from its target rate caused real exchange rate deviations from its equilibrium level. Also, changes in the rate of inflation in the outside world, changes in the nominal exchange rate and current account balance changes lead to a deviation of the exchange rate from its equilibrium level, but the effects of changes in capital flow on the exchange rate deviation from its equilibrium level were not statistically significant. But interactive effects showed that the inflation targeting policy played a significant role in measuring the impact of changes in the nominal exchange rate, domestic inflation and external inflation on real exchange rate deviations from Its balance rate. But this policy leads to a significant reduction in the role of current account and capital account changes in increasing the real exchange rate deviations from its equilibrium level.

In recent years the study of various costing pattern, led to revealing deficiencies for that and trying to improve them. However, because of the importance of cost and the advantage that recognizing it has in planning and rating of organizations, in this research has been tried to assessment of function of Time Driven Activity Based Costing (TDABC) pattern, compared to the classical costing in particular ABC, in service companies. This paper has an applied purpose and the analysis is descriptive by using correlation method. Financial records and documents were used to the collecting the data and finally the costs calculated by TDABC model and current model, then Student's t-test were used to compare the two samples. The results indicated that TDABC was more efficient than the classic costing, which used at Barakatel Company, for calculating the service's costs. This method can also apply by managers to finding out the idle capacities and costs for different purposes.

This dissertation aims to illustrate main requirements and barriers for making an e-Health model. We emphasized on a basic World Health Organisation‟s (WHO) definition and selected experiential strategic planning under discussion as a well-suit pattern for the e-Health care system. The resource based strategy was considered to present a holistic framework for an e-Health strategic planning. Further, an economical sub-model was essential to cover finances such as Return on Investment (ROI) and Technical Issues. While, there are many information management advantages, we have noted some problematic issues to highlight e-Health barriers. Since, we faced three main factors such as human, ICT and investment resource in e-Health care system, therefore, we selected two research methods. Both qualitative and quantitative methods were used to present social and natural science too. To do this, twice we conducted interviews with 75 e-Health experts. Finally, the holistic and conceptual model and financial sub-model were designed.
