The utilization of 3G and 4G is rapidly increasing and also cellphone users are briskly changing their consumption behavior, using preferences and shopping manner. Accordingly, cellphone manufacturers should create an accurate insight of their target market and provide a “special offer” to their target consumers. In order to reach a correct understanding of the target market, consumption behavior and lifestyle of the submarkets we found the appropriate number of community clusters after criticizing the traditional methods and introducing market segmentation techniques which were based on neural networks. By utilizing the fuzzy Delphi technique, variables of target market segmentation were found. Finally, the obtained clusters and segmentations of the market were refined by using the techniques of K-means and aggregation (Agglomerative). The population of this research included the consumers of mobile in Tehran with a sample of 130 specimens after collecting data through questionnair...
بررسی ديدگاه دانشجويان در خصوص جو آموزشی (مدل DREEM) در دانشگاه علوم پزشکی گلستان در سال 1390
Background and objective: The educational environment may be varied in different teaching and learning areas whether it is close to or away from standards. Educational climate is a representative of curriculum, dominant spirit on schools, and educational programs. Learning environment is a determining factor and is an indication of students' perception of their embedded learning circumstance. This study aimed to investigate the views of the students about their learning environment based on DREEM model. Materials and Methods: This cross-sectional descriptive analytical study was conducted in 2011 on 148 medical and paramedical students using cluster sampling method. Data was gathered by DREEM questionnaire consisting of learning, teachers, and students' perception of academic ability, educational climate, and social environment domains. The questionnaire total score was categorized in five groups; undesirable (0-50), semi desirable (51-100), somewhat desirable (101-150), good (151-200), and very good (201-250). Data was analyzed using descriptive and analytical statistics with p<0.05. Results: 3.4 percent of the students perceived educational climate as very satisfactory, 67.6 percent as favorable, 28.4 percent somewhat favorable, and 0.7 percent as low. There was a significant relationship between gender and educational climate(p<0.05). The male students had more positive view toward educational environment of the university than the female peers. Conclusion: The majority of the students perceived the educational environment of the university as optimum. Male students had more positive view toward educational climate of the university than the female ones.
بهینه سازی سیاستهای زیست محیطی بخش زراعت کشاورزی ایران مبتنی بر رهیافت بهینه سازی چندهدفه دوسطحی
2020
در طول سه دهه اخیر، با توجه به رشد جمعیت، رشد اقتصادی و مصرف انرژی، خطرات و آسیب‌های زیست‌محیطی بیشتر نمایان شده است. ایران کشوری رو به رشد است و یکی از مصادیق الگوی رشد با فشار بر منابع طبیعی محسوب می شود؛ از اینرو، بررسی اثرات زیست محیطی مصرف منابع طبیعی و توسعه در ایران بسیار حائز اهمیت است. هدف پژوهش حاضر بهینه یابی سیاستهای کشاورزی با محوریت حفظ محیط زیست و بهبود بهره وری اقتصادی از طریق ساخت یک مدل بهینه سازی چندهدفه دوسطحی و ارزیابی مجموعه جوابهای بهینة به دست آمده از دو نوع ابزار سیاستی «افزایش قیمت نهاده آب» و «برقراری مالیات بر کود مصرفی» بود. پژوهش به صورت مطالعه موردی در بخش زراعت کشاورزی دشت خمین و طی سال زراعی 95-1394 صورت گرفت. مجموعه جوابهای بهینه پارتو به دست آمده از ارزیابی سیاست افزایش قیمت نهاده آب و برقراری مالیات بر کود شیمیایی نشان داد که در الگوهای کشت شامل محصولات لوبیا و پیاز، بهره وری بالاتر و مصرف کود کمتر از سایر الگوهای کشت بهینه است؛ همچنین، تغییر الگوی کشت به محصولات پیشنهادی افزایش بهره وری مصرف آب به میزان 162 درصد و کاهش 29 درصدی میا...
The average of estimated prevalence of chronic pain in neighborhoods of Tehran was 25.5% and a large heterogeneity was observed in its prevalence in neighborhoods of Tehran. Prevalence of chronic pain was significantly higher in married housewives, retirees and pensioners and was significantly associated with age, educational status, depression and anxiety (P<0.05). The reliability of Bayesian method was confirmed by evaluation methods in this analysis. Conclusion: These results demonstrate prevailing amount of chronic pain at neighborhood-level in Tehran, which warrants careful attention to prevention, treatment, and rehabilitation by health care professionals.

تعیین ضرایب معادله آنگستروم و توسعه یک معادله رگرسیونی برآورد تابش خورشیدی (مطالعه موردی:منطقه مشهد)
2009
Solar radiation, nowadays has a lot of application in different fields of agriculture, irrigation, and hydrology engineering and due to these various applications, different models has been proposed for it’s estimation. Angstrom-Prescott equation is one of the most important well known models for solar radiation estimation. This equation has empirically coefficient that various for each location. In this paper, the data gathered in Mashhad Synoptic station during 1378 and 1380, Angstrom-Prescott coefficient has been identified according to the ratio of actual sunshine hours (n) to the maximum sunshine hours (N). Also a Regression local equation has been proposed considering several meteorology parameters including daily gathered data of saturation vapor pressure deficit, precipitation, air temperature mean, relative humidity percentage and n/N. Finally the proposed model has been evaluated according to the independent measured data during 1381 to 1382. The statistical analysis of th...
تحلیل برخوانی «آرش» بهرام بیضایی، با رویکرد ترامتنیت
University of Tehran, 2021
بهرام بیضایی، نویسنده، فیلم‌ساز، کارگردان تآتر، نمایشنامه‌نویس و پژوهشگر نامدار و صاحب سبک ایرانی است. او با بهره‌گیری از پشتوانه‌های اساطیری، حماسی، تاریخی و فرهنگ عامۀ ایران و جهان، به خلق اثر می‌پردازد؛ از این رو، آثار او پیوندهای عمیق و گسترده‌ای با زمینه‌های فکری و بن‌مایه‌های فرهنگی ایران و سایر ملل جهان دارد. نمایشنامۀ «آرش» او نیز، واجد چنین ویژگی شاخصی است. باید بیش از پیش به این نکته توجه کرد که بر اساس رویکردها و نظریات بینامتنی، آفرینش‌گران، در خلق آثار خود چندان به داشته‌ها، آموزه‌ها و اندوخته‌های بکر ذهنی خویش تکیه نمی‌کنند؛ بلکه آن‌ها را با مد نظر قرار دادن متون از پیش موجود، تدوین می‌نمایند، که خود این متون بنیان فرهنگ، اندیشه، هنر و ادب زمانۀ خویش هستند. در پژوهش پیش‌رو، کوشیده‌ایم به روش تحلیل محتوا و با تکیه بر مطالعات کتابخانه‌ای و اسنادی، و کاربست نظریۀ «ترامتنیت» ژنت(از نظریه‌پردازان بینامتنیت)، متن نمایشنامۀ «آرش» را تحلیل کنیم. دستاوردهای پژوهش گویای این است که این نمایشنامه(برخوانی)، مشتمل بر عناصر بینامتنی، بیش‌متنی، فرامتنی، سرمتنی و پیرامتنی با بسامدی درخ...
ماهیت زبان در اندیشه سوسور و فارابی
جستارهایی در فلسفه و کلام, 2019
With the critique of the historical-comparative trends surrounding language, Saussure sets intralingual elements as his point of departure. In his view, the realized and dynamic nature of language does not reflect its true nature. Therefore, it is necessary to consider the static aspect of language or the synchronic approach to language. Saussure, under the influence of Kant's epistemology, separates the domains of language into langage, langue and parole, and restricts the concrete object, or in some way language principles, to the langue. Farabi has explored linguistic reflections in the tradition of Islamic philosophy in a close relation with Saussure. He begins his linguistic studies with a fresh and new reading of the associations between language and logic. By arguing that speech (notgh) and logic (mantegh) are derived from the same root, he traces back the origin of logic to language. In the idea of Farabi, speech is the fundamental and general aspect of language. He summarized three realms of language into rational soul (Nafse Nateghe), inner word and outer word, where the inner word is home to linguistic elements. Irrespective of this issue, in semiotics, the relationship between the signifier and the signified is arbitrary in a way that is comparable to that of speech and logic. The present paper, by delving into three domain of language proposed by Saussure, seeks to exhibit that this structuralist conception is not new. For centuries, in the tradition of Islamic philosophy, Farabi has elaborated on such reflections. Farabi's notion of dividing linguistic signs into two parts of speech and logic and the tripartite division of language offers a new conception of linguistics, which marks the beginning of a new trend of studies in Islamic linguistics.
