Ecotourism is a tool for achieving the goals of sustainable development, because it offers similar solutions to current problems. Iran is one of the most attractive countries in the world, which is among the top countries in the world in terms of climatic diversity and archeological and civilizational monuments, but unfortunately, in terms of ecotourism attraction and income, it does not have a worthy position. With coherent and systematic planning, the country can be saved from economic stagnation and dependence on oil, and the ground can be prepared for more employment and preservation of national reserves and resources. At the same time, ecotourism has the highest efficiency and effectiveness in using natural and cultural capabilities, which, while using it efficiently and creating conditions for employment and income generation, has the least negative impact on the environment and is a suitable tool for its development. It is in developing countries. For Iran, given its potential and actual tourism potential, the development of this industry can be considered as one of the appropriate options, despite the recent years and efforts in five-year plans based on the country's 20-year vision. Good activities have been done in this field, which in comparison with the increasing growth of world tourism, these activities do not seem to be sufficient at all, and in this regard, the city of Paveh, despite the various natural and cultural capabilities to properly exploit the gifts. And the benefits of this industry require proper attention, planning and investment, and efficient management in this sector. This research was conducted by descriptive-analytical method using a questionnaire and statistical analysis using SPSS software. The results showed that the tourism infrastructure conditions of Paveh city can not lead to the development of tourism in Paveh city at present and should provide more infrastructure services to think about tourism development and economic conditions resulting from tourism development is not good and basic plans should be created in this regard to It is possible to achieve the economic development of the region before the development of tourism. Also, marketing conditions have been able to lead to the development of tourism in Paveh city on average, but more efforts should be made in the field of advertising and marketing.

Nowadays, most of Businesses have faced a great challenge for entering a new market. The existence conditions have forced the managers to apply the innovative methods for simultaneous analyzing of various factors for arrival to special markets. This paper prioritizes a few target markets using two methods. First, the problem is solved by the combined method of hierarchical analysis and Monte Carlo simulation, and then by the method of fuzzy hierarchical analysis and finally the results of both methods are compared. The considered problem in this study relates to a factory of prefabricated building components that is looking for establishing the sale agencies in appropriate towns in order to introduce and distribute the new products. In order to prioritize cities, desired criteria are determined through interviews with experts and investigating the previous studies. The research findings have shown that based on the four main criteria and seven related sub-criteria, the prioritization of selected cities as markets has been A-D-C-B respectively. In the end, it is concluded that based on the findings of this study, managers and stakeholders should pay attention to these priorities in choosing the target market. In this research, for the first time, the combined Monte Carlo technique and hierarchical analysis have been used to select the market. Market selection is one of the issues that has always been a concern of managers and has been associated with a lot of risk. Using Monte Carlo simulation algorithm and hierarchical analysis, by considering different decision intervals, greatly reduces the risk of selection, so this technique is recommended to managers of organizations as a practical method in market selection.

This paper examines the gap between marginal cost and the price of 22 manufacturing industries in Iran at ISIC 2-digit level and 32 industries at a 3-digit level during 1995-2015 compared to selected countries. It examines the gap by using the Hall-Roeger model. We found that in garments, basic chemicals, non-metallic mining, and refined petroleum products, the price and marginal cost difference are high and in tobacco industries are low. In 3 out of 22 industries at ISIC 2- digit level and in 11 out of 32 industries at 3-digit level, Iranian industries have higher markups and a significant gap between price and marginal cost than Japan, Germany, France, and the United Kingdom. Also from 32 industries in ISIC 3-digit level and 22 industries in 2-digit level, Iran has the lowest mark-up in the tobacco industry with 1.03 and in chemical products with 2,33, has the highest markup.

The purpose of this study was to investigate the effects of perfectionism on the reduction stress and athletic burnout in football players. The statistical population of this study included all football players at youth level in Guilan, Iran. 378 players were selected as a sample size through random sampling method. A combination of valid and reliable standard questionnaires was distributed to collect the research data. Research hypotheses were analyzed by the Kolmogorov-Smirnov test, Pearson correlation coefficient, and linear regression. The SPSS software (version 24) was used for data analysis (α≤0.05). The results showed that there was a significant correlation between athletic burnout and positive perfectionism (-0.622), negative perfectionism (0.555), problem-oriented strategy (-0.358), and emotion-oriented strategy (0.401). According the results of this study, developing efficient plans with focusing on the psychological variables of perfectionism, stress, and athletic burnout can improve the coaches’ awareness of coaching behaviors as well as increasing athletes’ optimal mental performance and efficiency.
