In ancient Iranian myths, many kings are named who possessed many attributes. Among them Kay Khosrow was distinctive as innumerable attributes are mentioned for him, which depict him as a human with “Farrah” (Divine Splendor) and a perfect human. One of his main characteristics setting him apart from other legendary kings of ancient Iran was the story of his eternity. There is no trace of this part of the story in the Avesta, but it still depicts the period of his monarchy as brilliant. The story of eternity is more prominent in other religious texts of Zoroastrianism. In the myths of ancient Iran, many kings were mentioned who had many features and characteristics.One of the most important features and characteristics as well as his differences with other mythical kings of ancient Iran is the story of his immortality. We do not find any trace of this part of the story in the Avesta, but there we will find his reign very brilliant, and in other Zoroastrian religious texts this story appears and has a greater effect.

In Avestan, Kay Kavus or Kauui Us an is introduced as great and the most glorious king of Kayanian dynasty. He has divine royal glory (khvarenah or farre izadi) which gives him special features. One of these features is “flying to heaven” and companionship with Ahura Mazda. But in the passage of time, the myth of Kay Kavus has changed. He has fallen from his high state and has turned into an idiot king that kills his son, Seyavash; His flying to heaven is interpreted as invading the divine territory and wishing to conquer heavens. The present article, after presenting the myth of Kay Kavus, tries to consider the reasons of his “flight to heaven” and change in the myth. Then, the original structure of the story will be revealed by displacing some of couplets of the story in Shanameh.

Background: Ischemic mitral regurgitation is a major source of morbidity and mortality of myocardial infarction. Surgical intervention for significant ischemic mitral regurgitation at the time of coronary artery bypass grafting (CABG) is controversial and has always presented a great challenge. The purpose of this study was to describe the current surgical options for ischemic mitral incompetency and to discuss when mitral valve repair via the Kay method may be favored over mitral valve replacement. Methods: Twelve patients candidated for the Kay mitral valve repair plus CABG were recruited. The efficacy of mitral valve repair was echocardiographically recorded at follow-up. To validate the diagnosis of ischemic mitral regurgitation, we conducted a detailed chart review— which included all preoperative cardiac imaging tests at the first, sixth, and 12th postoperative months, as well as the operative records and pathology reports. Results: Twelve patients (5 male and 7 female) underwent CABG plus the Kay mitral valve repair. All the patients had significant mitral valve incompetency, which was resolved in all of them (P<0. 05). There was no preoperative or postoperative mortality. No further postoperative mortality was reported at 1 year’ s follow-up. The Kay technique for mitral valve repair had a desirable result insofar as 8 (72. 7%) patients had only mild mitral regurgitation and 4 (33. 3%) had mild-to-moderate mitral regurgitation. Conclusions: In the current era and in Iran, mitral valve repair— especially via the Kay method— has been proven to confer improved short and long-term survival, decreased valve-related morbidity, and enhanced left ventricular function. Future randomized prospective clinical trials are needed to compare this cost-effective surgical technique with its counterparts.

One of existing challenges in reading a portrait miniature is assessing the meanings and concepts of the work through a systematic analysis. Such reading with superficial analysis can be helpful to know the values of the portrait miniature of Iran even better. Therefore, in various schools of art, a number of techniques are fundamentally examined in reading the contents of the works and some of them have been developed in reading portrait miniature of Iran. Content and intertexualcriticims are of that kind. One of the new techniques in such field is «iconograghy» which can effectively analyse the hidden parts of the work in a systematic way. The aim of this research is reading the contents of the portrait miniature in a background level and improving the reading of iconograghy in criticizing Iran’s portrait miniature works. The depicted image of «the battle of Kay Khosrow and Shidah» has been studied for this reason. Since such kind of criticism is based on social and historic information with some backgrounds of the work and symbols related to the same period the story written, in the first step the research has been carried out through gathering documentary information, then with some adaptation done in two different studies, «composition» and «visual symbols» of the work explored. The understanding of the atmosphere the image created during that period can be important in revealing some other dimension of the work, knowing the hidden motifs of the story and cultural understanding in which the work depend on, can help the writer to read and perceive the image better as well. The study demonstrates that the division of the page into two side and colored balance between the component parts of the work, with some complication exist in the atmosphere of the work other than the main characters of the epic, intensifying the confrontation between the two corps and all of these factors show that unlike few corps fighting with each other on the depicted image, a real battle are going on between them. On the other hand, the image’s content and adaptation of the work with religious principles and beliefs prevalent during the Safavid dynasty can lead us to revealing some dimension of the work and on this course some similarities among historic, religious and national characters of Iran can be drawn.

Proverbs are rooted in the culture of any language and as a result, they can be considered as one of the criteria for measuring the main elements of language. The present study also seeks to investigate the usage of color words in Persian and English proverbs based on the theory of Berlin and Kay (1969) so that the results are a criterion for measuring the taxonomic studies in relation to the main color words of these two languages. The theory of Berlin and Kay (1969) states that there is a hierarchy of 11 universal color words as the most obvious Universalist approach to color words. The results of this research showed that despite the existence of slight differences in the hierarchies of the main global color words, the hierarchies of the main Persian color words and the hierarchies of the main English color words with the hierarchies used in the present study, significant similarities can be observed both in their number and order. As a result, it is clear that the color words that have been introduced as the main color words of these two languages based on the theory of Berlin and Kay have been widely used in the culture of these two languages for a long time and have been in a way unknown, and entered the structure of proverbs. The comparative analysis also showed that although out of the total of 11 universal color words, 8 color words are used in Persian proverbs and 10 color words are used in English proverbs, the hierarchy of colors terms in Berlin and Kay (1969) are similar.

The Qur'an contains religious values ​​for the advancement of man to happiness. The claim is that Quranic teachings are the basis of religious values; By choosing it better, the method of proving religious beliefs can be extracted. This research tries to extract the method of proving religious beliefs with a business approach and by using artistic forms with a descriptive and analytical method and with a better selection of Quranic teachings. Based on the verses, the process was defined as the introduction to the institutionalization of religious values ​​in the businessman 1- Gaining self-knowledge (knowing the talents, capacities, existential dimensions and position of man in the universe); 2- Gaining monotheistic insight (knowing the origin and your relationship with the Creator); 3- Reciprocity is (knowing the destination and drawing the path of happiness in the universe). After the realization of these three stages, the beliefs must be proven through rational and scientific reasoning and penetrate, in this case, the acceptance of good qualities in the businessman will be facilitated.

In this paper we used orthogonal basis functions and expansion coefficients for inverse modeling of magnetic data. The basis functions chosen are normalized eigenvectors of second derivation of the objective function (Hessian matrix) calculate for an initial model. Limited number of basis vectors obtained in this way defines a new subspace in model parameters space. Anew objective function is defined in term of these new parameters and minimized in subspace of original space. As in geophysical inverse problems we need to inverse matrixes that are functions data and geometry of data and model parameters. The matrix inversion in new subspace of the original space will be better conditions due to less dimensionality in the inversion. Since the most significant eigenvectors corresponding the largest Eigen values in Singular Value Decomposition (SVD) of matrixes. Others eigenvectors have less influence in fitting data or lead inversion procedures to local minima. With apply subspace method inversion will be fast and stable against the noise. The efficiency of the method is tested with synthetic and real magnetic data (acquired from Moghan area, north-west of Iran). The results proved fast convergence and stability of inversion against the noise.
