Information hiding and data encryption are used widely to protect data and information from anonymous access. In digital world, hiding and encrypting of the desired data into an image is a smart way to protect information with a low cost. In the digital images, steganalysis is a known method to distinguish between clean and stego images. Most of recent researches in this scope exploit feature reduction algorithms to improve the performance of correct detections. However, dimension reduction alone could not tackle the problem of steganalysis because the properties of stego images change during the steganalysis process. In this work, it is intended to propose an Image Steganalysis using visual Domain ADAPTATION (ISDA), which this steganalysis target images to distinguish across stego and clean images. ISDA is a dimensionality reduction approach that considers the image drifts during the steganography process in the steganalysis of target images. Moreover, ISDA employs domain invariant clustering in an embedded representation to cluster clean and stego images in the reduced subspace. The results on benchmark datasets demonstrate that ISDA thoroughly outperforms all of the state of the art methods on validation parameters, accuracy of detection and time complexity.

Introduction. Nursing research activities have a growing trend. Data collecting by a questionnaire is one of the important stages of research. Up to now, lots of questionnaires have been developed in today’s world languages and been used in different countries. The questionnaires usually are translated or developed individually as needed and still some researchers do not believe in acceptance of standard guideline about translation process. Research tools psychometric experts; frequently insist on a correct translation process of questionnaires and by not paying attention to this important issue, internal and external findings couldn’t be compared with each other. Attainment of consensus standards for proper translation, enhance the translation quality of tools and cause to increase the cooperation and partnership between researchers from different cultures and improve the common results. Researchers and questionnaire designers have taken many steps in translation and cultural ADAPTATION of questionnaire. The goal of this article was to introduce important steps of translation process based on maintaining the cultural equivalences. Conclusion. The quality of an instrument used in cross-cultural research is expected to vary with quality of the translation method in different researches. Therefore, there is a need for consensus among researchers in how to achieve the quality of instrument translation. 

Background: Tobacco use has a serious impact on health and socioeconomics situation of general population. Majority of people has started it in teen age and the most of them will probably be addicted. Meanwhile, school-based interventions can play an essential role in prevention or delay tobacco consumption, but there is no structured program for such interventions in Iran. Current study has been designed to provide a national evidence based guideline for school- based interventions.Methods: We conducted wide search main databases and websites considering Pub Med, NICE, GIN, NGC, SIGN and other related websites for defined keywords. Related guidelines were selected and appraised by two independent experts using AGREE-2 tool. The highest record was translated to Persian and discussed in panel of guideline for adopting with Iranian culture and condition. The preview was sent to experts and stockholders for final edition and then was published for pilot application.Findings: Eleven related guidelines retrieved in which only two were about school-based interventions recommended. The main recommendations for prevention of smoking was as following: Pay attention and take the organizational wide approaches in schools, plan and do interventions by adults, plan and do interventions by peers, train, retrain and develop, and pay attention and take the coordinated approach.Conclusion: Iranian school based guideline is a well adopted tool to prevent tobacco consumption in teen ages.

Introduction: Adaptive response is one of the important concepts in radiobiology. The present report aimed to transfer the radio-ADAPTATION via serum. Material and Methods: In total, 50 male adult Wistar rats were randomly divided into 6 groups, including control, serum control, low-dose (100cGy), low-dose/lethal, serum/lethal, and lethal (8Gy). Exposure was carried out by a linear accelerator (Elekta Synergy® Platform) with a 40×40cm field size. The animals were monitored in terms of the endpoints of the survival rate, and at the first stage, the rats were exposed to the low doses of radiation. Subsequently, the serum was injected intraperitoneally under sterile conditions 6 h after low-dose exposure. The Kaplan Meier Survival Curve was used to evaluate the survival rate (P<0. 05). Results: There was a significant difference among different groups regarding the survival rates. Moreover, a statistically significant difference was observed between low-dose/lethal and low-dose/serum, lowdose/ lethal and lethal, and low-dose/serum and lethal (P=0. 001). Similarly, there was a statistically significant difference between the control and experimental groups regarding the survival rates (P=0. 001). Conclusion: To the best of our knowledge, this method can lead to immunological responses or unknown mechanisms that result in the increased survival adaptive response to subsequent high-dose radiation.

The recent technical advances in cinema as well as the lack of original and attractive narratives, are the two essential reasons of a need to make the cinematic application of the rich and dramatic literary works. This article, considering the significance of cinematic ADAPTATION both in Iran and other countries, demonstrates that Seirol-Ebad of Sana’i enjoys the characteristics to be dramatized as a movie. This work, due to its fictionality, picturesque narrative, original images and the distinct but organized episodes has the capacity to be turned out to a three-act screenplay. Meanwhile, the rich content and the moralistic dimension of the work which are in harmony with its atmosphere and images can be a great support for an invaluable ADAPTATION.
