Pilonidal sinus is an inflammatory disease that occurs acutely and chronically in the sacrococcygealregion. The pathogenesis of the disease is not precisely known and the treatment of choice is surgery; which can be done in different ways. In the present study, the results of two open and semi-closed surgical methods were investigated and compared.

A total of 150 patients with pilonidal sinus referred to Bandar Abbas Shahid Mohammadi Hospital who were candidates for surgery were randomly divided into two equal groups including group 1 with open surgery and group 2 with semi-closed surgery. P value < 0.05 was considered significant.

In the current study 150 patients were analyzed which divided into two groups consisting of 75 patients in each one of them and one group (group 1) and another group (group 2) were treated with open and semi-closure techniques, respectively. In group one were 52 male and 23 female patients, in group two 53 male and 22 female, group one and two average age were 26.17 ± 8.4 and 25.81 ± 8, respectively.

Overall results of the study demonstrate that there is no significant difference between the two procedures on recurrence and postoperative infection perspectives and also there was a significant privilege in semi-closure technique on hospitalization time, healing period, avoidance of work perspectives. And also this study demonstrated there is no significant relationship between demographic features and side effect incidents.

Employees are valuable asset that create competitive advantage for the organization and thus it is very important for human performance on the stage of competition, and thus, emotional intelligence has effects such as motivational effect and greater effectiveness in employees and the creation of an intimate and environment, leading to development in the organizational positive line. The aim of this study is to investigate the effect of emotional intelligence on motivation and performance of carpet weavers. The research method has been descriptive and survey and it has been applied. The statistical population in this study is all weavers of the Zarrin baft weaving company of zanjan, which is based on the Morgan table, 201 in the method of random sampling. In order to collect the required data, from the (2005) emotional intelligence questionnaire (2004), the Wright job motivation (2004) and organizational performance questionnaire (2008) and questionnaire validity were approved by cronbach's alpha, using the model of structural equation modeling for investigating the relationship between dimensions and research variables from the perspective of respondents. The results showed that emotional intelligence has a significant impact on the motivation and performance of the weavers of weaving carpet weaving in zanjan. In particular, self - awareness, managerial self - awareness, social awareness and management of relationship on motivation and performance of carpet weaving company have a significant effect.

Many cities in Iran have specialized human resources and appropriate medical facilities, and have the potential to attract tourists. What is essential in realizing these capacities is the recognition of tourists' mental image of the potentials of therapeutic tourism destinations. The purpose of this study was to identify the factors affecting the development of therapeutic tourism.

 The study was a descriptive survey in Tehran, Iran, during summer and autumn of 2018 and winter of 2019. First, 38 factors influencing the development of therapeutic tourism were identified, and then by Delphi method, 34 factors were identified for formulating a questionnaire. With the reliability and validity of the questionnaire, a sample of 432 health tourists in Tehran with a history of frequent referral were selected randomly. Data analysis was performed using exploratory and confirmatory factor analysis methods.

 By factor analysis, six main components were identified as factors affecting the development of therapeutic tourism. The factors affecting the development of tourism were as the quantity of health services (human resources and facilities available), quality of health services, living conditions, amenities and tourism, socio-cultural characteristics, advertising, and information.

Despite the importance of quantity and quality of health services, due to the increasing demand for travel, patients traveling to receive treatment need more services, and consider the level of service development in different aspects. One-dimensional attention to the expansion of health care cannot guarantee the development of this type of tourism, and the supply of other tourist needs, such as recreation, favorable living conditions, and pleasant memories, is a sufficient condition for development.

Urban tourism is a significant factor in development of cities and tourists always travel to visit the tangible or intangible attractions of cities. Tourism shaped base on the presence of historical, cultural-artistic attractions and one of the most attractive tourist places in cities are the facilities and structures builds around. Therefore, development of urban tourism and its wise management requires planning. In the meantime, citizens have a significant influence on this development, because in most of the metropolises of the world, in policy-making and management structures, in line with the processes of globalization, they want more participation and participation of citizens. This research aimed to identify useful factors of citizenship on urban tourism development in Yazd city. Using this survey among a selected sample of citizens of Yazd, using exploratory/confirmatory factor analysis method, extracting the components of citizenship. By naming the components and validating the structural model, the results indicate that citizenship components can be categorized into five factors, which explain 59.056 percent of the total variance. The importance of the citizen's duties factor is 31.579 percent of the variance compared to other factors, because citizens from Yazd, the components of citizenship duties can have the most significant impact in development of urban tourism. The factors of technology literacy targeted thinking, social participation and global consciousness are among other factors influencing the formation of the personality of citizenship.

In this paper the closed-loop supply chain network design problem is modeled and solved in a competitive and uncertain environment. The competition between two supply chains is on the price of products in forward channel and the price of returns (incentives) on the reverse channel. Demand is price sensitive and the amount of returned products is also linearly dependent on the incentives. Fuzzy set theory is used to cope with uncertainty. The proposed bi-level model is proved to be concave then we turn it to a single level model which is also proved to be a concave one. Afterwards, the single level model is solved using the Benders Decomposition approach. Finally, computational results are presented based on data inspired from real case. Results show that the proposed algorithm is converged in reasonable iterations. Increasing the price elasticity coefficient (intensifying competition) leads to less profit and Increasing the rival’s price elasticity coefficient leads to more profits for the existing chain.
