Abstract: 

در دو دهه قبل توانایی های فنی بشر برای تولید و جمع آوری داده ها به سرعت افزایش یافته است. بطور کلی استفاده همگانی از وب و اینترنت ما را مواجه با حجم زیادی از داده و اطلاعات می کند. این رشد انفجاری در داده های ذخیره شده، نیاز مبرم وجود تکنولوژی های جدید و ابزارهای خودکاری را ایجاد کرده که به انسان یاری رسانند تا این حجم زیاد داده را به اطلاعات و دانش تبدیل کند. داده کاوی به عنوان یک راه حل برای این مسائل مطرح می باشد. داده کاوی را می توان عمل استخراج اطلاعات پنهان در یک پایگاه داده بزرگ تعریف کرد. داده کاوی به تحلیلگران برای پیدا کردن الگوها و روابط بین داده ها کمک می کند. یکی از مهمترین زمینه های داده کاوی کشف قوانین وابستگی یا Association RULES mining می باشد که هدف از آن یافتن قوانین الگوهای پنهان در بین حجم زیادی از داده ها است. همچنین چگونگی کاوش در بین داده هایی که حاوی اطلاعات زمانی هستند به عنوان یک مساله مهم در امر داده کاوی مطرح است. از آن جایی که بعضی از اقلام داده در کل پایگاه داده به وفور تکرار نمی شوند، در صورتی که در یک بازه زمانی دارای درجه پشتیبانی (support) بالایی هستند،Temporal Association RULES mining به کشف قوانین موجود در یک بازه زمانی در پایگاه داده می پردازند. یکی از مسائل مهم در زمینه کاوش در داده های زمانی چگونگی تقسیم بندی داده ها به بازه های زمانی می باشد. در این مقاله با ارائه روشی که از الگوی تقویمی برای مشخص کردن بازه های زمانی استفاده می کند و ترکیب آن با روشی که از گراف رابطه بین اجزای پایگاه داده استفاده می کند به استخراج قوانین موجود در این بازه های زمانی پرداخته می شود.

Abstract: 

از بین سیستمهای حمل و نقلی راه آهن اقتصادی ترین و ایمنترین ابزار جابجایی بار و مسافر محسوب می شود که ترافیک را کاهش داده و حداقل آلودگی را برای محیط زیست به دنبال دارد. یکی از کلیدی ترین راههای حفظ و ارتقا جذابیت جابجایی با استفاده از راه آهن برای مسافران و صاحبان بار، ارتقا سطح ایمنی است. طراحی و پیاده سازی سیستمهای ایمنی نیازمند آن است که از شرایط خاصی که در سطح شبکه راه آهن ما ناامنی ایجاد می کند آگاهی کافی وجود داشته باشد. بسیار اتفاق می افتد که سوانح به دلیل عدم توجه به شرایط مشابه در گذشته به وقوع می پیوندد. لازم است مسوولان ایمنی این صنعت با بهره جستن ازتجارب حاصل از سوانح گذشته، زمینه تکرار آنرا در آینده از بین ببرند. استفاده از تکنیکها و ابزارهای جدید و به روز، می تواند دیدی متفاوت با انچه تا به حال از تکنیکهای آماری توصیفی توسط متصدیان ایمنی راه آهن ارایه گردیده است. جهت ارتقاء سطح ایمنی بوجود آورد. مقاله حاضر تحقیقاتی است که برروی داده های سوانح ریلی راه آهن ج.ا.ا بدین منظور صورت پذیرفته است. در این تحقیق با استفاده از تکنیک association RULES که یکی از تکنیکهای کارآمد داده کاوی محسوب است. به تحلیل داده های سالهای 75 تا 85 سوانح راه آهن ایران پرداخته شده است تا روندها، ارتباط بین فاکتورهای سوانح و الگوهای تکرار شونده ای که در نگاه اول و با استفاده از تکنیکهای آماری پنهان باقی می مانند، استخراج گردند. همچنین لازم به ذکر است جهت انجام تحقیقات از متدولوژی CRISP-DM و نرم افزار Clementine استفاده شده است. در انتها با تکیه بر دانش و تجربیان مستند شده حاصل از تحلیل داده ها دستورالعملهایی ارایه گردیده است که با پیاده سازی آنها از تکرار الگوها، روندها، و ارتباطات شناسایی شده موجود بین فاکتورهای سوانح در آینده پیشگیری شود.

Abstract: 

Family, as the first social institution, affects the society larger than itself. The importance of the family as the key element of each sound society and strengthening relations between couples outline necessity of legal arrangements. Since females suffer more damages and losses due to collapse of the family so formulation of more SUPPORTIVE laws is required by the legislator. Therefore regarding Iranian civil law, support of the legislator from females married with foreign nationals and priority of each provision of the law of Iranian females married with foreign nationals has been compared and studied in present research in order to protect the family in direction of stability of marital relationships. Results obtained from this study show that SUPPORTIVE laws are limited in case of Iranian females married with foreign males and there is no essential support. Thus the necessity of more supports is felt based of importance of the family.

This policy avoid the majority of the alleged imposition of cultural values and suggest discussion and open dialogue in order to the way for thoughtful review in cultural community wealth”. Nevertheless, domination of the political process in social process on SUPPORTIVE policy is also considered as the fundamental challenge in theoretical perspective and Models of cultural policy- social.

Abstract: 

Amitraz is a triazapentadiene, an α2 adrenergic agonist and a member of the amidine chemical family. A limited number of human intoxication cases have been published in the literature. Lack of a clear and specific protocol for the therapy of amitraz intoxication may make its successfully managed case reports useful and valuable for other clinical practitioners in poisoning departments.The case is about a 22 years old female, single, university student, ingested a glass of amitraz poison (about 100 mL of a 20% solution) as a suicidal attempt on 11:30 am which was about 3.5 h before her hospital admission. She found nausea, vomiting, and dizziness. Immediately, her family took her to a clinic near their house. At that clinic (13:30 pm) she had miosis and they did gastric lavage , one adult dose of activated charcoal (50 g) and referred her to our Poisoning Emergency Department, where she was managed SUPPORTIVEly and successfully.Amitraz is a poisonous chemical which may cause central nervous system depression and also respiratory/cardiovascular symptoms as well. Several studies reported that using atropine for those amitraz poisoned patients with both miosis and bradycardia resolved the problem and recommend it as the first line of drug therapy when bradycardia occurs from vagal stimulation and atrioventricular block.Management of amitraz poisoning is still considered to be SUPPORTIVE and symptomatic. Although the effects of activated charcoal and cathartics have not been studied, they may still be considered for treatment.

Abstract: 

The steps that universities can take to promote and improve entrepreneurial activities and communication with industry is one of the important topics that has attracted a lot of attention. This study investigated selected universities in the world in the field of entrepreneurship, through a survey study to prioritize options to support entrepreneurship in Iranian universities based on the opinions of experts. Data collected by using information available on official sites and related documents. In the second part, the hierarchy analysis process was used. The findings showed that the supporting activities of universities were as follows: science-educational, cultural-incentive, material support, and spiritual support. Hierarchical analysis showed that in SUPPORTIVE activities of universities, the criterion of achieving upstream goals with a relative weight of 0. 341 had higher priority than other criteria. Also, the material support was considered to be the best alternative with a relative weight of 0. 284. Other alternative supports were as follows: science-educational, spiritual support, and cultural-incentive, respectively.
