The tourism destination image is one of the most important and debatable topics in marketing research in the tourism industry. Because, it influences both the choice of travel destination and the future behavior of tourists. Despite the importance of this concept in the development of the tourism industry, the subject of the image in studies of Iranian tourism has not received notable attention. Therefore, the purpose of this study was to evaluate the tourist images from Tabriz metropolitan before and after their trip. The research was conducted by descriptive-analytical and survey methods. In this regard, a well-defined questionnaire was used to collect the data. The study analysis has been done by using descriptive statistics analysis, one-sample t-test, paired t-test and Pearson correlation coefficient method(s). The results of this study showed that visiting of Tabriz city caused a significant positive change in the tourist image. There is also a significant positive correlation between tourists' image with their willingness to re-travel to this city. Recreation, leisure activities, and visiting of tourist attractions were the most effective motivations for traveling and choosing of Tabriz as a travel destination. The important point in conjunction with the ways of getting information of the tourist’ s destination is that the significant development of social Medias operate as new forms of word of mouth advertising alongside its traditional form (friends and acquaintances) in producing the tourist's previous cognition and images prior to their trips to the our case study. The results of the present study would be beneficial for image management and tourism development activities of Tabriz metropolitan.

Travel and tourism are the most important sectors of the global economy that can lead to income generation and employment. Therefore, in this research, which is of descriptive-correlation type and was conducted as a survey, the study of the relationship between luxury values and customers' attitudes towards the intention to buy has been applied in a practical way. The statistical population of the present study includes tourists who ate in the spring and summer of 2020 in luxury restaurants in Gilan province, which was used to sample the available method, and its data was collected using a questionnaire. Data analysis was performed using structural equation modeling in PLS software environment. The results show that the significant relationship between luxury values and customer attitude and purchase intention was confirmed and also the relationship between customer attitude and purchase intention with the mediating role of food image is significant.

As international travels have become increasingly common for both business and tourism, physicians are confronted with innumerable travelers suffering from unknown syndromes and infectious diseases, thus it is necessary for physicians to maintain familiarity with current guidelines and recommendations about travel medicine and prevention of related infectious diseases.Fever, travelers' diarrhea, skin eruptions, respiratory and CNS involvement are diseases seen among travelers on return which make them visit the physicians.Consultation and a check up prior to traveling with the aim of immunization, recommendations about traveler's diarrhea, malaria and diseases transmitted by blood or sexual contacts are steps that could be taken by the physicians before travel. Knowledge about the epidemiology and etiology of traveler's diseases, destination and immunization status of travelers can prevent complications, morbidity and mortality attributed to infectious diseases in travelers.

Attar’ s Manteq Al-Tair is a magnificent masterpiece in mystical literature that through presenting the most essential ontological issues invites humans to contemplate them. This interdisciplinary study seeks to analyze the journey in parallel universes in Manteq Al-Tair based on the principles of quantum physics to achieve a rational plan for responding to the paradoxes of this literary work; since in quantum mechanics actualizing all probabilities and paradoxes is feasible. According to the findings, Attar is in search of an exact twin of his own (Simorgh) in another world by creating such a story. In view of the contradiction in time travel, the starting part of the journey is based on the hypothesis of “ compatible dates” and the final part of the journey is based on “ periodic dates” . The mirror symbolizes the “ Wormholes” (launching platform to the parallel world) and “ Mount Ghaf” , like the “ event horizon” , is a passageway to enter other life dimensions along the borderline between this world and the parallel world. In addition, there is a structural palindrome among them and Nur Alnur can also be a factor for launching forwards into a parallel universe. Attar intends to reach the truth of universe by attaining integrity and completeness. Einstein also intends to read God’ s mind through integrity theory. However, both Attar and physicists believe that one cannot enter parallel worlds by the existing knowledge.

Purpose: The study purpose was to determine and compare the Recall and Precision of Bing and Google image search engines for content based image retrieval. Methodology: The research used webometrics and comparative methods. Population includes images stored in the databases of Bing and Google search engines, and research sample includes 15 selective images searched in any of search engines. All the retrieved sources through the images by image content based image search were gathered, results’ Recall and Precision measures were calculated by relevance formula and their average percentage were obtained. Research hypotheses were tested by U Mann-Whitney test as well. Findings: Findings showed that the Google search engine functionality was higher with recall measure of % 88. 73 than recall rate (%20. 86) for Bing. But Bing search engine had higher precision (% 99. 86) than Google (%94. 80). Results: Hypotheses tests on recall and precision in two search engines’ image retrieval showed a significant difference for recall in favor of Google, indicating its better functionality than Bing but there was no significant difference between them concerning precision since both showed fair precision however Bing was relatively useful.

In this paper, an alternative approach in operational modal analysis is presented, utilizing image processing technique and transmissibility functions. Imaging sensors do not impose additional mass on the structure due to their non-contact nature, while transmissibility functions, independent of excitation type, can directly extract mode shapes. The innovation of this research lies in combining these two techniques to record dynamic responses and identify modal properties. To capture the temporal response history from video signals, the block-matching method with sub-pixel accuracy was employed. Validation was conducted by recording the response of the tip of a cantilevered steel beam subjected to impact excitation, using a high-speed camera and a laser vibrometer, simultaneously. The RMSE plots in the time domain and the PSD in the frequency domain indicate high accuracy of this method. Using this approach, the displacement time histories of various points on the structure were extracted from the video signals, and the modal properties, including natural frequencies, damping ratios, and mode shapes, were identified using the transmissibility matrix method. The results obtained from the proposed method were compared with the stochastic subspace identification (SSI) method and analytical solutions. The findings reveal the accuracy of the modal identification approach introduced in this article. The highest relative error in estimating the natural frequencies of the first and second modes, compared to the values from the laser method, are 0.19% and 0.13%, respectively, and in comparison to the analytical values, they are 0.34% and 1.5%, respectively.

In Kant and the Problem of Metaphysics (KPM), Heidegger shows how the initial image-making power of the imagination is pictorial in the pure image of time. He further clarifies the recognized link between the syntheses and the time-visualizing power of images which is pictorial formative power, which can visualize time. The three syntheses of imagination are replaced with the modes of existence of Dasein. Three kinds of photographs resemble the images produced when the transcendental imagination functions as Dasein. We can address the ways to visualize time by considering Dasein with a photographic preoccupation through 1. A possible look in the form of presentation (a photograph shows an immediate look of a house or person as intuitable this-here); 2. An immediate look of the thing, house, or deceased person, as well as a copy or its reproduction as a death mask; and, 3. The manner of contemplation of a likeness is an immediate look of a being present in the form of representation.

The main objective of this research is the role of virtual spaces in the familiarity and mental image of foreign tourists traveling to Iran. This research is in terms of its purpose and in terms of collecting descriptive-survey information. The statistical population of this study is foreign tourists visiting Iran. A sample of 200 individuals was considered as a sampling method and the Standard Mang and Choi Questionnaire (2016) were distributed among these individuals. To analyze the data, SPSS and PLS software were used. The results showed that Web surfing and the use of social networks have a significant effect on emotional evaluation. The results also showed that the use of social networks and emotional assessment has an impact on the mental image of foreign tourists, but web browsing does not affect the mental image of foreign tourists.
