Background: Short-STEM prosthesis for total hip arthroplasty (THA) have been designed to overcome the weakness of standard-STEM prostheses and improve surgical outcomes. The aim of this study was to compare short-STEM with standard-STEM prosthesis outcomes.Methods: This study was performed as a randomized clinical trial. Subjects were selected among patients referred to Sina University Hospital, Tehran, Iran from April 2010 to 2012. THA were performed with short-STEM or standard-STEM prostheses after obtaining written informed consent from patients. Balanced block randomization method was used to get a random sample in each group. Clinical outcomes were evaluated based on Harris Hip Score (HHS). Patients were followed up for at least one year. All patients were examined at 2 weeks, 6 weeks, 3 months, 6 months and one year after surgery. In each visit, Control X-ray was obtained and bone and prosthetic position were assessed. Also, the symptoms such as infection, pain, claudication, ability to climb stairs, using crutches and weight bearing were rechecked. Student t-test was used to compare outcomes in the two groups.Results: A total of eighty four THA were studied. 13 patients were lost to follow-up or had infection and failure. One patient died with the prosthesis in situ from causes not related to the surgery. Therefore, a total of 70 patients were analyzed. Of these, 34 and 36 hips underwent small STEM and standard STEM THA, respectively. The mean age of the patients at the time of operation was 61.1±8.68 years (range, 48-86 years). Most common reasons for arthroplasty were osteoarthritis, avascular necrosis and dysplasia of hip. There were significant differences between the two study groups in bleeding during surgery (P=0.001). There were no significant differences among the study groups in HHS except for 6th week and 3th month (P=0.000).Conclusion: The use of short-STEM prosthesis can improve the performance of patients in short-term but no significant difference with standard-STEM prosthesis in long- term.

education is a continually developing activity, it shapes the way an individual develops their attitudes, thoughts and behavior. education is not just about being literate but it is an overall development of the person in every aspect of their lives. A society's educational sySTEM can be greatly linked to its culture as the culture that one is in have an affect on the type of curriculum the institutions will develop in order to cater to every individual of that particular culture. education moulds and shapes a society and it is influenced by the culture of the particular country or society. The educational sySTEM acts as a point of reference for the society's needs and demands. The principles that dominate this article is culture and education are interrelated and interconnected. Every educational paradigm is influenced by the culture of the society in which it operates. This essay underlines the extensive connection between culture and education. As a result, the goal of this essay is to depict these features from a Philosophical-Psychological Approach.

Abstract Intuition is one of the characteristics of entrepreneurs and an important factor in the decision-making processes of entrepreneurs. In recent years, at the same time as the development of entrepreneurship as an interdisciplinary science, intuition and providing different definitions of it have not been noticed by researchers and researchers in this field, and many researches have not been written in this field. This is despite the fact that in other fields of humanities, especially management (with which entrepreneurship is closely related), basic sciences and even medical sciences, there is a suitable background and theoretical literature about this. On the other hand, it seems that the theoretical and epiSTEMological foundations of this concept have not been researched as much as necessary in the few researches that have been conducted, and very little research has been done in this field. In this article, firstly, the definitions and researches about intuition are reviewed, and secondly, the little researches that have been done in entrepreneurship and its relationship with other sciences are discussed.

Knowing the components of economic education provides the dynamic background of education in this field. The aim of the current research is to investigate the indicators and components of the economic education curriculum. The approach of the current research is qualitative and its method is research synthesis. The research community is all the articles (211 articles) that have been presented from 1390 to 1401 AD and from 2010 to 2022 AD regarding economic education in curricula. The sample of the research is 32 articles, which were selected based on thematic monitoring, theoretical data saturation, and purposefully. The research data were collected from the qualitative analysis of the studied articles. By analyzing the data, the dimensions of vitality in the curriculum of the elementary school in 4 factors and 55 categories including the dimension of individual factors (including indicators and components related to personality characteristics); The dimension of culture and economic ethics (economic fields in the society); The dimension of economic concepts and knowledge (indices in economic education) and the dimension of collective and communication concepts (communication and interaction indicators in education) were classified. Economic education is dependent on internal and external components in educational sySTEMs, which requires macro-planning in this field.

Introduction: Academic faculty members need to emphasize ethical principles in order to improve higher education, with the understanding of this importance, the current research was conducted with the aim of designing the ethical model of academic faculty members in Iran's higher education. Material & Methods: This research is a type of qualitative study that uses foundational data theory. The participants, including experts and faculty members of the country's public universities, who were responsible for the promotion of academic members, were selected as key informants through a targeted sampling method of 45 people. Data were collected through semi-structured interviews. The reliability and validity of the data were obtained from the two methods of reviewing the participants and recoding by experts. Data were analyzed by open, central and selective coding. Results: The results showed that the moral model of faculty members in Iran's higher education is explained in 10 main categories and 27 subcategories. Major and core categories in the form of 6 dimensions of causal conditions including (individual factors, organizational factors), core (cultural-educational, educational ethics, research ethics, scientific-executive), background conditions (higher education policies, moral activism), intervening conditions (environmental factors), strategies (micro level-university, macro level-higher education) and consequences (individual and organizational) were elevated to a higher abstract level and finally the research paradigm model was presented. Conclusion: The regulations for the promotion of academic staff members in Iran require a detailed revision of the content with an ethical and qualitative approach in order to make the indicators of the promotion regulations efficient and effective.

Water Water deficit especially after heading is one of the most effective factors of wheat yield loss in Iran and across the world and identifying the physiological traits related to plant resilience is of great importance in screening for tolerant varieties. The objective of this study was to evaluate the variation in STEM reserves accumulation capacity and its relationship with remobilization in some wheat cultivars. 22 wheat cultivars were cultivated in a split plot design with three replications, full irrigation and 40% of field capacity being main plots. The amount of accumulation and remobilization was estimated by measuring internodes weight and STEM soluble carbohydrates content (WSC). Significant genotypic variation among cultivars was observed under both normal and drought conditions. Maximum accumulation was found in lower internodes followed by peduncle and penultimate using dry weight measurement method. In WSC measurement method, however, maximum accumulation was observed in penultimate followed by lower internodes and peduncle. Cultivars ranking based on accumulation was also different in two methods. Drought stress caused decline in internodes weight, WSC and yield and remobilization efficiency. The specific STEM weight had the highest correlation with remobilization. Significant correlation was found between grain yield and remobilization, specific STEM weight and WSC.
