Abstract: 

2Various researches have shown that Iran's educational system does not pay enough attention to cultural differences and mostly promotes the dominant and official national culture in an engineered way. The focus of these researches has been focused on the inputs of the educational system. The current research, relying on the mixed exploratory method, tried to examine both the inputs and educational processes in order to test the truth of this claim, whether such a claim is consistent with the reality in the educational system. In this way, in the qualitative part, first the teachers' lived experiences of the criteria that were considered for their selection and employment were analyzed (inputs), and then in the quantitative part, the teacher's success in the classroom was analyzed. It was predicted based on the mentioned criteria (processes). The findings of this research showed that scientific identity and ideological identity are valued in the recruitment of teachers, and because of this, criteria such as personal success, special privileges, and religious and moral foundations are put forward. However, it is only the teacher's personal success that can predict his success in the classroom. This shows that the ideological identity is only manifested in the inputs and is practically not institutionalized in the classroom and teaching processes. In this way, considering Iran's educational system as ideological does not match the realities of the educational system.

Abstract: 

The difficulty of extracting Multiple concepts from an indivisible essence is one of the main motivation of interest to negative theology. On the other side, believing in the identity of the essence and attributes of God without clarifying the nature of ascribing of attributes to God’s essence is not precise, too. In spite of the variety of solutions to this issue, it seems no one is satisfiable. In this paper, after examining these solutions, we will show that, according to the fact that God is the origin and source of all perfections and the fact that the grantor does not lack the thing he grants, we can ascribe the attributes purified from defects to God although we don' t know the nature of this ascription.

Abstract: 

The trend towards using multimedia in e-learning environments as the preferred basis for teaching (particularly when teaching at a distance) has increased dramatically, particularly over the last few years. This paper will report on a current research project being conducted at the University of Southern Queensland (USQ), involving the development of a multimedia version of an existing print based course. Specifically, it will analyze relevant instructional design (ID) issues and reflect on the concepts involved in catering for a multi-literate clientele and how the use of Multiple representations may enhance the learning opportunities of students, primarily post-secondary learners. Firstly, it will investigate the role that learning styles play in the learning process and what should be considered when preparing instructional material, looking closely at the importance of visualization in the representation of concepts and the current understandings of what it means to be literate in a culture saturated with visual elements. It will be seen that our understanding of these basic concepts will play an important role in our ID approach to teaching and learning, particularly when using visual and/or Multiple representations in the multimedia and e-learning environments. Secondly, it will investigate the cognitive constraints experienced by learners when information is displayed in Multiple ways in such an environment and whether it will be beneficial to learner cognition to provide users with a level of interactive choice. Finally, a set of instructional design recommendations will be made as to an appropriate format and potential way forward for the delivery of multimedia and e-learning instructional materials.

Abstract: 

Summary Multiple reflections are coherent seismic noises whose presence, especially in marine data, lower data quality. In this research "dual-tree rational dilatation wavelet transform" Or DT-RADWT is used to attenuate Multiple reflection noise from seismic data. The advantage of this transform to the dyadic discrete wavelet transform, is its fractional sampling, which allows for higher timefrequency resolution. The proposed algorithm in this research is wavelet domain noise analysis or WDNA, in which DT-RADWT and split Bergman iteration algorithm are used. WDNA is a data-based algorithm. The split Bergman iterative algorithm is designed to quickly obtain the optimal solution. Radon transform is a common method to attenuate Multiple reflections, and it is used to obtain the initial pattern of Multiple reflections. The purpose of WDNA is to improve Radon transform output and to better maintain primary reflections. The presence of high levels of random noise reduces the quality process of noise reduction, but WDNA is designed to overcome the adverse effect of random noise. The WDNA results in Multiple reflection attenuation have been tested by synthetic and marine data, and their results have been compared with Radon and WDGA outputs. The results show good improvement in seismic data quality using WDNA algorithm in comparison with Radon transform. Introduction The reflection waves, which is reflected between the subsurface or free surface reflectors more than once before being received on the receivers, are called Multiple reflections. Multiple reflections, often destructively interact with the primary reflections and reduce the quality of the seismic image. An inverse filter based on predictive deconvolution using the periodic feature is used to attenuate Multiple reflections in the water. Multiple and primary reflections show different moveout and travel-times, This property is the basis of the theory of many Multiple attenuation techniques such as CMP stacking, F-K filter, and Radon transform. Radon transform was first introduced by Johann Radon (1917) and for the first time, parabolic Radon conversion was used as a Multiple attenuation technique by Hampson (1986). Since then, the Radon transform became one of the most widely used tools to suppress Multiple noises. Goudarzi and Riahi (2013) presented WDGA method based on the data type, as an efficient way of attenuating various seismic noises. However, this approach, if there is a high level of random noise in the data, cannot well separate the coherent noise from the reflections. Here we try to introduce a new method to solve this problem. Methodology and Approaches The proposed method in this research is called wavelet domain noise analysis (WDNA) algorithm. Similar to WDGA, this method is based on data, but because of the use of the split Bergman iteration is less sensitive to random noise. It also reduces the time to reach an optimal solution and it has better convergence. These features enable better detection of the desired noise and better signal separation from the noise. The goal of this research is to apply the benefits of Radon transform, and at the same time, to use the DT-RADWT wavelet transform capabilities to provide high resolution. We take advantage of the split Bergman iterative algorithm to build a full Multiple reflection model from initial Multiple models (achieved from Radon filter). Finally, in the DT-RADWT domine, full model of Multiple reflections would be subtracted from the input data, and thus, the filtered data would be obtained. Results and Conclusions In this research, the WDNA algorithm has been introduced and its application in attenuating Multiple reflections from seismic data has been investigated. The WDNA algorithm is based on the data and requires an initial noise model that is obtained from Radon transform (or any other suitable filter) to attenuate Multiple reflections and in the dual-tree wavelet transform domain, it is used to produce a complete noise model with the Bergman iteration algorithm. Subtracting the full noise model from seismic input data yields almost no Multiple reflection noise and the initial reflections are well maintained. The use of the DT-RADWT wavelet transform increases the frequency resolution and split Bergman algorithm helps to achieve a fast convergent solution that also causes insensitivity with random noise in the attenuation process of Multiple reflections. The results of applying the WDNA method on synthetic and real data have resulted in better outputs than Radon and WDGA.

Abstract: 

Purpose: To report a patient with MEWDS.Patient and findings: A 65-year-old man presented with sudden decrease of vision in his right eye. On ophthalmoscopy of the involved eye, numerous small discrete white lesions were detected superficially and deep in the retina around the disc and macula. On visual field examination, enlargement of the blind spot was detected. Fluorescein angiography was unremarkable. On electroretinography, the a-wave was decreased minimally. The patient was followed and after 2 months, significant improvement of visual acuity and visual field was observed.Conclusion: MEWDS is a rare intraocular inflammatory disease of unknown etiology and in contrast to our patient, more frequent in females. The natural course is generally benign with spontaneous disappearance of the lesions and improvement of vision in 6 to 8 weeks.

Abstract: 

Introduction: Myocardial bridging is a congenital condition in which a segment of a major epicardial coronary artery has an intra myocardial route. Myocardial bridging is usually confined to a single vessel and is typically the mid segment of the left anterior descending artery. Bridging may be associated with chest pain, myocardial infarction, and sudden cardiac death, or usually asymptomatic.Case Report: A 59 year-old women with diabetes mellitus and hypertension presented with dyspnea and chest pain on exercise. Physical exam, electrocardiography and echocardiography were intact. In angiography, we found severe stenosis of left main coronary artery and severe stenosis of three coronary artery (Three Vessel Disease) as well as Multiple myocardial bridges at the end of right coronary artery.Conclusion: Myocardial bridging is a rave condition, however, it be considered in patients facing recurrent chest pain, it has severe complication such as sudden cardiac death.
