The purpose of this case study was to measure satisfaction of some postgraduate engineering students at Shiraz University about virtual and remote laboratories. The participants were 18 electrical engineering students selected from Shiraz University through purposeful samples. The studied variables in order to measure the satisfaction of remote laboratories included students' focused attention during the use of the virtual laboratory (FA), perceived usefulness of virtual lab (PU), virtual lab approval by students (Confirm), students' satisfaction with the virtual laboratory(Satisfaction), fun and enjoyable virtual lab (Play), easily perceived by students in using a virtual lab (PEU), Attitude to the virtual laboratory (Attitude), tendency to use the virtual lab continuously (ICU), quality of virtual laboratory design (QD). Results revealed that students' satisfaction with the virtual laboratory was above the middle standard rating. Furthermore, from the students' point of view, the quality of the virtual laboratory had a significant effect on their "Satisfaction" with the virtual laboratory (Sig. 0.000, B = 0.885), and from the perspective of the students, the QD had a significant effect on ICU (Sig. 0.000, B = 0.937). Finally, the regression analysis showed that the QD had a significant effect on students' attitudes toward the virtual laboratory (Sig. 0.000, B = 0.885).

Since tourism causes some positive occupational movements, produces lots of job opportunities and it could have a great amount of effect on the geographical aspect and on people’s lives and society, it is believed that, it is the third and the most dynamic industry in today’s life. The cities specially in developing societies a living place for human kind face with same limitations of source and financial, social condition, it is buffer to vary the non – cultural activities such as tourism . This can be a means to increase job opportunities, decrease poverty and welfare state and social security .This study has been done in one of the scopes of Fars province, Iran. It aimed to investigate what advantages& limitations of the tourism development in Marvdasht city. it also sought to find out how the tourism in this area can be developed .This research was on the basic of descriptive – analytic nature and does have some practical goals .Required data in this field was gathered by library – based method .This study aimed to investigate some strategies to develop the tourism in Marvdasht city and it was done by determining strengths , weaknesses , opportunities and threats by SWOT model .The results of the research revealed that inner elements and outer factors of final scores are located in the ST or competitive scope . The most significant strategies of this scope are: dynamic economics and safe job opportunities by optimum use of tourism capacity.

Introduction: The aim of present study was to determine the effect of biofeedback training on electrical activity of trapezius muscles and range of motion in people with shoulder impingement syndrome. Martials and Methods: In this study, 20 patients with shoulder impingement syndrome in age range of 20-40 y were selected as the statistical sample and were divided into experimental (n=10) and control (n=10) groups. The experimental group trained by using EMG biofeedback for 8 weeks and 3 sessions per week. The control group was applied only for pre-test and posttest measurements. For data collection, surface electromyography was used to analyze the muscle activity patterns of trapezius muscles (upper, middle, lower), and a goniometer was executed to evaluate the flexion. Shapiro-Wilk test was used to confirm the normality of the data and covariance analysis test was applied to compare pre-test and post-test. Correlated t-test was used to examine within-group changes. Results: In this study, after 8 weeks of biofeedback training in the experimental group, a significant improvement in the electrical activity of the middle trapezius (P=0.000) and lower trapezius muscles (P=0.016) was observed. In addition, a significant improvement in the amount of flexion range of motion (P=0.000) was indicated in the experimental group compared to the pretest and also the control group (P=0.05). However, no significant difference was shown in the muscle activity of the upper trapezius muscle (P=0.776). Conclusion: The present study showed that biofeedback training is effective to improve the electrical activity of trapezius muscle and flexion in people with SIS.

  Diversity of economic activities, agglomeration of educational centers, concentration on technological initiatives and information generation, possession of the most important cultural centers, and arrangement of the most significant artistic and cultural events in Tehran Metropolis have provided a large-scale potential for cultural and educational activities and a special condition for cultural tourism development; however, tourism development plans adopted by Tehran officials are slight proportional to its regional capacities and have thus proved unsuccessful to reach a perceptible and appropriate tourism development. The chief objective borne by this research is, accordingly, identification of the factors and indices impacting on Tehran’s cultural tourism development, which, with respect to sundry commonalities of this type of tourism and creative and cultural industries, focuses on these factors, as well. Indices have been extracted through literature reviews and their content analysis. Using Delphi questionnaire, afterwards, experts’ and urban planners’ opinions and comments were extracted in two stages. Results of the first stage of Delphi questionnaires graded indices in Interpretive Structural Modeling (ISM). Outcomes of the second stage were analyzed byMICMAC software to determine impacts and susceptibilities of the indices on each other. Results of the study show that the index Rules and Regulations is graded in the level 10 and the indices ‘ Suitable Institutional Partnership and Labor Division among Different Actors of Industry’, ‘Political and International Relations’, and ‘Existence of Cultural Tourism Attractions’ are graded in the level 9 aimed at development of Tehran Metropolis’s cultural tourism. In fact, indices of the levels 9 and 10 are fundamental ones to which more attention should be paid with regard to results of interpretive-structural analysis in development of Tehran cultural tourism.
