Abstract: 

"عامل اثرگذار" واژه ای آشنا برای اغلب جامعه علمی و پزشکی است، ولی با وجود استفاده گسترده و اغلب وسواسی، معدودی بطور کامل معنی یا کاربردهای آن در واقع مجادله های راجع به آن را درک می کنند. در این مقاله نحوه اندازه گیری و استخراج این شاخص موثر و برخی مسایل مربوط به آن (بویژه سو استفاده از آن به عنوان سنجشی از شایستگی نویسنده) بررسی می شود.

Abstract: 

Nowadays, the fundamental role of having a purpose for life in physical and mental health has been confirmed. According to victor frankl, presence of a purpose in life gives life a meaning and increases resilience against pains and traumas. The importance of the purpose in life construct reveals the need for a reliable and valid tool to measure it. Crumbaugh and Maholick's purpose in life questionnaire is the first and one of the most applied tools for the assessment of life's purposefulness. The aim of this research is to determine the factor structure of purpose in life questionnaire. The questionnaire was administered on 206 students who were selected through random stratified sampling at Ferdowsi University of Mashhad. Exploratory factor analysis showed that there are two factors "comprehension" and "purpose" and this finding were confirmed by confirmatory factor analysis. Altogether results of this research showed factor validity of the purpose in life questionnaire with a two factor pattern

Abstract: 

There is a growing attention to models which contain a broader set of economic data. In recent decade, introduction of Factor Augmented VAR models through augmentation of traditional VAR models with unobservable “ factors” has made a new route to econometric modeling. In spite of the growing number of international papers and researches which have used FAVAR approach to modeling policy shocks to various economies, there is little about Iranian economy. So the paper is an attempt to fill the gap in the literature using an FAVAR model to analyze transmission of oil and monetary shocks to Iranian economy. The model contains 35 major macroeconomic annual variables spanning from 1974 to 2014. The results show that “ real sector” of Iranian economy responds positively to oil shocks up to 5 years. Also “ nominal sector” of the economy responds positively to oil shocks but the responses are shorter, smaller and more volatile than “ real sector” responses. Finally the model results show responses of “ nominal sector” of Iranian economy to monetary shocks are positive which its duration varies between 2 and 4 years.

In the previous quarterly of jurisprudence and the principle of law (No 15), there was an article as execution of a sentence of stoning to death during the absence of Imam of our time. Its author was Jamileh Kadivar. Although she indicated that it is true but in her article, she said that stoning is not in favor of people. She criticized it in her all article.This article criticizes her point of view and indicates that this rule is necessary.

Abstract: 

احراز هویت دوگانه به روز ترین روش تامین امنیت دسترسی به منابع شبکه می باشد. این روش در عین سادگی و کم هزینه بودن، امنیت دسترسی به منابع رایانه ای را تا حد قابل توجهی افزایش می دهد. این طرح راهکاری را ارائه خواهد داد که با بهره گیری از مزایای احراز هویت دوگانه روشی مقرون به صرفه جهت پیاده سازی انبوه این نوع از احراز هویت در سطح کشور ارائه خواهد کرد. از آنجایی که بیش از90 درصد از سیستم های احراز هویت در داخل و حتی خارج از کشور بر مبنای کلمات عبور ثابت، قابل استفاده مجدد و قابل حدس مورد استفاده قرار می گیرند که این مساله خود بزرگترین مشکل امنیتی در مورد آنها تلقی می شود. به دیگر سخن، با افزایش امنیت تمامی بخش های جانبی مرتبط با فرآیند احراز هویت نیز نمی توان این ضعف ذاتی سیستم های سنتی را نادیده انگاشت. در این پروژه مطالعات اولیه روی روش های احراز هویت دوگانه انجام و یکی از این روش ها به صورت نرم افزاری پیاده سازی گردید.

Abstract: 

Introduction: Knowledge management is a significant determinant for the survival of organizations.Identification of key success factors and an effective approach facilitate decision making on knowledge management. This study aimed at identifying factors and indexes for effective implementation of knowledge management in hospitals to investigate their relationships through a conceptual model and confirmatory factor analysis technique.Methods: This study was divided into two parts. The first part was exploratory which involved a literature review and an exchange of ideas with experts to identify indexes. The second part was a survey which included data collection through a questionnaire and the use of structural equation modeling for data analysis.The population consisted of managers, vice-chancellors and physicians at public and private hospitals in Tehran. The samples were selected randomly. LISREL software was used for data analysis.Results: According to the results, four factors of process, structural-cultural, technological, and managerial capabilities were effective in knowledge management at the significant level of 0.01, and managerial capability had a mediating role. Furthermore, the presence of clear objectives at the beginning of a knowledge management project, available information technology infrastructure, employment of a special team for knowledge management implementation and participation, and the support from senior managers appeared to be the most effective factors.Discussion: According to the results, all four factors influenced the effective implementation of knowledge management in hospitals and deserve proper attention. Previous studies showed disproportionate growth in technological factors whereas other factors were overlooked.

Abstract: 

Cardiovascular diseases (CVD) are the leading to of death throughout the world. The world health organization (WHO) world health report 2006 reported that 18 million people die from CVD every year. Intravascular thrombosis due to fibrin aggregation in arteries is anmain cause of CVD. Fibrin is the primary protein component of blood clots. Which are formed from fibrinogen by thrombin (D.voet&voet). The insoluble fibrin fibre is hydrolyzed into fibrin degradation product by plasminogen activators such as tissue plasminogen activator (t PA), urokinase and factor XII .In this researchwe consider to analyzed the sequence of (t PA), urokinase and factor XII in order to identify conserved sequence regions and possible similarities and differences and compare relationship between of biological functions and structures. In this regard the sequences of tissue plasminogen activator were extracted from uniport KB/ swissport and entries in FASTA format and the data were analyzed by FASTA protein program. Results revealed that the tissue plasminogen activator sequence 96% similar to urokinase-type plasminogen activator and 59% similar to coagulation factor XII that all of them contribute to fibrinolytic activity.

Abstract: 

Over the past seven decades, strategic management has been one of the most important areas of study for business schools, as well as practical areas for business and commerce around the world. At the same time, it has seen significant progress in terms of developing covered areas. To know what a strategy is, it is best to be more familiar with its evolution. The periods of evolution and growth of strategic management can be examined from different angles. In this paper, an attempt is made to examine the evolution of strategy. The present research is applied in terms of purpose and is of the type of library studies with a review approach. The evolution of this research includes the study of historical developmental periods of strategy, the course of space-related to strategic research, the course of thinkers and their proposed theories, the time course of strategic management, and course in research journals in this field, which is mentioned in detail in the article.

Abstract: 

مطالعه فوق یک مطالعه رتروسکوپتیو بوده که در مرکز تحقیقات ناباروری رویان انجام گرفته است.بیماران منتخب مربوط به آغاز سال 1377 تا اواخر سال 1379 می باشند. گروه Tubal factor به عنوان گروه کنترل برگزیده شده اند. 33 بیمار مبتلا به PCO که قبلا حداقل 6 بار تحریک تخمک گذاری باکلومیفن سیترات قرار گرفته بودند با 76 بیمار مبتلا به نازایی بدلیل عامل لوله ای، از نظر نتایج IVF، مقایسه می شوند. در این مطالعه فقط سیکل اول IVF تحت بررسی قرار گرفته است.جهت استنباط آماری از آزمونهای پارامتری Fisher’s exact test, K2, Anov, T.student و در صورت نیاز از آزمونهای Non parametical (K.W) استفاده شده است.پروتکل انتخابی: long protocol (بوسرلین HMG/)بیماران مبتلا به PCO در این مطالعه دارای متوسط سنی کمتر از (4.2±28.5 در مقابل 5.3±32 روز)، مدت زمان فاز فولیکولی از شروع HMG تا HCG بیشتر (2.8±12.3 در مقابل 3.2±10.9 روز)، بروز OHSS بیشتر (17.6% در مقابل 2.7%) و pregnancy rate/Embryo transfer بیشتری (20% در مقابل 1.4%) نسبت به گروه کنترل می باشند (P<0.05).اما در موارد زیر اختلاف واضحی بین دو گروه وجود ندارد: طول مدت گرفتن GnRHa تا شروع HMG (13.3 در مقابل 12.6)، وجود cyst بعد از دریافت بوسرلین (12.1% در مقابل 23%)، درصد موارد تخلیه cyst (3.03% در مقابل 10.5%)، تعداد آمپول HMG مصرفی (31.8% در مقابل 29.09)، تعداد oocyte بدست آمده (7.6 در مقابل 6.7)، تعداد جنین تشکیل شده در هر فرد (5.1 در مقابل 4.6)، تعداد جنین انتقال یافته در هر نفر (2.7 در مقابل 3.06) و cancel سیکل (0 در مقابل 5.9).در این مطالعه، فرض 1 (برابر بودن میزان P.R/E.T در دو گروه) رد شد و فرض 2 (بیشتر بودن میزان OHSS در گروه PCO نسبت به (Tubal factor تایید گردید.
