The purpose of research is to evaluate the ergonomics of sports equipment located in parks and public spaces in Tehran. For this purpose, 4 areas of Tehran municipality were selected as study sites and 2 parks and 2 recreation areas were selected from each. Three devices were evaluated. REBA technique was used for posture assessment and William Fine method was used for risk assessment.Three devices were evaluated. The REBA technique was used to assess posture and the William fine method was used to assess risk. The PMBOK, 2000 model was also used to provide risk reduction solutions. The results of the posture evaluation show that working with the Rotary ship rudder has a very high risk (the risk number is higher than 13). After that, the device "leg and underarm Press" has a high risk level (risk number 9). Finally, the "elliptical" device has an average risk level (risk number 6). rank and risk level of the sports equipment studied were evaluated based on 2 separate methods. results indicate that in both evaluation methods, the lowest level of risk assessed belonged to the elliptical device. But the results of the methods used differ between the highest risk levels assessed for the sports devices studied. So in the posture assessment method (REBA),ship's Rudder had the highest degree of risk, while according to the William fine assessment method, the leg and underarm Press showed the highest level of risk. General solutions for risk management include: aggressive, defensive, conservative and combined solutions.

The main purpose of this research is to identify and analyze the effective factors of establishing a knowledge-based city in less developed areas. The research method is mixed (qualitative-quantitative). To carry out this research, in addition to studying documents, the ground theory method with MAXQDA12 software was used to identify the effective factors. The statistical population in this research was all experts in the field of public management, urban management, economics, managers of knowledge-based companies, and managers of Sistan and Baluchestan governorate and Zahedan municipality, which was conducted after conducting 17 theoretical saturation interviews. Finally, open, central, and selective codes were extracted and in the quantitative part, Dematal technique was used to determine the effectiveness of the effective dimensions on the establishment of a knowledge-based city. According to the semi-structured interviews, 6 dimensions (cause, main phenomenon, contextual, interveners, strategies, consequences) and 15 components (core codes), and 69 indicators (open code) were extracted for the establishment of the knowledge-based city. The Finding showed that dimensions of development, skill and expertise, education and technology, infrastructure, internationalization, institutional factor, urban knowledge development, knowledge management, foreign policies, laws and regulations, cultural-native, knowledge-based city development, policies, domestic, cultural conflict, and urban geography, in order from high impact to low impact, as well as dimensions of urban geography, cultural conflict, internal policies, knowledge-based city development, cultural-native, laws and regulations, foreign policies, knowledge management, knowledge development urban, institutional factor, internationalization, infrastructural, education and technology, skill and expertise and development are respectively from high effectiveness to low effectiveness.

Hospitals are the most important part of the healthcare system. Statistics show that a significant portion of health budgets are allocated to hospitals. The continuous impact of information technology on hospitals’ performance has led to perfect competition. Accordingly, this study aimed to evaluate the quality indicators of hospital services considering information technology using a hybrid approach of the Kano model, Analytical Hierarchy Process (AHP), and Quality Function Deployment (QFD). In this regard, based on related studies, a total of 18 needs were recognized to evaluate the service quality of a hospital. The statistical population of the study consisted of patients of the hospital and due to the difficulty of access to the patient, a limited sample of 50 patients was selected. After collecting data, the identified needs were classified into three categories called basic, functional, and motivational using the Kano model, and 7 needs were set as basic needs. Then, using the AHP technique, the importance of the basic needs was calculated and considered as the input of the QFD model in the next phase. After providing some solutions based on the literature to meet these 7 needs, solutions were ranked and prioritized using the QFD model. Since the organization had limited resources, the Pareto technique was used to respond to 20% of these strategies and achieve 80% satisfaction. The results of the study showed that the hospitals can achieve 80% satisfaction by implementing the strategies of “holding ethics training courses online” and “creating team spirit and using health information technology in the hospital”, respectively.
