Recognition and identification analysis of the features of the epistemology of the MOOC (Massive and Courses)

Background and Objectives: One of the forms of knowledge acquisition in the current era is the distance education system, which has changed the traditional teaching methods, made it possible for everyone to learn everywhere and at any time, and has established social justice in the distribution of resources and facilities. It has created the necessary conditions for standardized education and in accordance with the needs of individuals and society, as well as the significant help that this system can easily and timely modernize education, save time, money and energy consumption, create opportunities for continuing education for employed people, strengthen specializations and creates calmness and reduces anxiety. And given that in addition to classroom teaching at the university, distance learning is now a valid method worldwide and UNESCO and other educational organizations around the world emphasize the expansion of distance learning, it is necessary to seriously develop it and the foundations of epistemology; and make it known to policymakers, planners and learners.The present study was conducted with the aim of identification and assessing the epistemological characteristics of MOOC (massive and courses). Methods: For this purpose, two methods of exploratory search (qualitative) and a questionnaire (quantitative) method were used. In the qualitative part of the research environment, the relevant electronic sources related to the subject matter of the research including 20 related articles were selected. In the quantitative section from the statistical population of 60 specialists in planning distance education in 2018 in the country a sample of 36 people was selected through voluntary sampling. To analyze the qualitative data, content analysis method and content validity index were used for analyzing quantitative data from mean weight and Friedman test. Findings: The results of content analysis indicated that four episodes of the learner, the content, teaching organization and educational environment can be investigated in MOOC epistemology (massive and courses). A total of 35 criteria were identified and confirmed. Quantitative results show that improving the level of information and digital literacy of professors, and knowledge with previous cognitive structures are the most important criterions of the epistemological characteristics of the courses of MOOC; and the criteria of ease of usedigital content, the recruitment of information technology professionals, for knowledge courses and the provision of Internet-based learning group environment, are the most important criterion for epistemology of massive MOOC. Conclusion: The results showed that in the epistemology of massive courses the dim   ===================================================================================== COPYRIGHTS  ©2020 The author(s).

Investigating the Impact of Collagen-Chitosan Derived from Scomberomorus Guttatus and Shrimp Skin on Second-Degree Burn in Rats Model

Background: The present study focused on burning as one of the main causes of mortality with detrimental economic and social effects in the world. The purpose of this study was to investigate the impact of collagen-chitosan gel extracted from Scomberomorus guttatus and shrimp skin in the treatment of second degree burn healing among rats. Materials & method: To fulfill the purpose of the study, chitosan and collagen were extracted respectively from shrimp and Scomberomorus guttatus skin waste by the acid-based method and were evaluated by using Pico Tag, SDS-PAGE. The burn wound healing efficiency of marine collagen-chitosan gel was examined in vivo using rats. Three different ratios of collagen and chitosan blend (Col-CH, 1:3, 1:1 and 3:1) were prepared to obtain the most effective Col-CH gel for burn wound healing and were compared to the animals treated with silver sulfadiazine ointment. Healing burn wound was studied by measuring wound surface area with Image J and histopathologic examination was carried out based on the mean of epithelialization, fibroblastic cells, acute and chronic inflammatory cells, angiogenesis, structure collagen and the amount of collagen on days 15 and 25 post-burn. Results: The results of SDS-PAGE indicated that the extracted collagen was type I and it was composed of two α (α1 and α2) chains. Amino acid analysis showed a much higher glaycin content in extracted collagen which amounted to one-third of the total amino. The wound surface measurement showed a significant reduction in wound size in the group treated with Col-CH (3:1) compared to silver-sulfadiazine treated group on 15th and 25th days. Histopathological findings represented a high score in epithelialization, collagen, collagen structure, fibroblast cell and a decrease in inflammatory cells infiltration in Col-CH (3:1) treated group on 25th day. The most obvious finding of the present study is that chitosan-collagen gel (3:1) represented a better efficacy compared to sulfadiazine in burn wound healing on day 25 post-burn. © 2021 The Japanese Society for Regenerative Medicin

Genealogy of imperfect construction of open education in Iran

Open education, in light of an amazing technological development, has transformed the educational system with changes in "educational culture" and an emphasis on the "learner-centered" principle. Since this has not been taken into account in Iran's educational system, the present article critically examines the issue of imperfect construction of an open education system in Iran. To analyze the issue historically, a genealogical method propounded by Foucault has been applied. Genealogy explains the evolution of historical moments in their internal power relations, as Foucault says: it is a discourse which intertwines power and knowledge. The "genealogical analysis" refers to an epistemological strategy formed in various domains of history, political and social sciences. To explain the aforementioned problem, we need to focus on both traditional and modern education discourses in the discursive space of open education. In response to the main question of the article i.e., what could have caused the imperfectness of open education in contemporary Iran? The findings indicate that "neglect to scientific software and discursive aspects", which followed the dominance of instrumental scientific view; "immature understanding of open education" which reduced it to complementary education and "bureaucratic relations" which are in conflict with the democratic character of post-modern education, have all led to the "imperfectness of open education" which has deepened the challenge of the alienation of "science" from culture and society

In addition, the findings showed that there is a significant difference between pre-requisite capabilities in dictation lesson including visual, Auditory and movement skills in the end test of experimental and control group showed significant differences between dictation and pre-requisite elements

Comparative assessment of three algorithms to control a deformable mirror for an adaptive optics system with no wavefront sensor

The images obtained from confocal imaging systems present less resolution than the theoretical limit due to imperfection of the optical components and their arrangement. This imperfection deteriorates the wavefront and introduces aberrations to the optical system. Adaptive optics (AO) systems composed of a wavefront sensor (WFS) and a deformable mirror represent the most used solution to this problem. Such adaptive optics systems are expensive. In addition, in microscopy, WFSs cannot be used due to stray reflections in the system and high aberrations introduced by the specimen. For these reasons, sensor-less AO systems have been developed to control the deformable mirror (DM) using an optimization algorithm in an iterative manner. At each iteration, the algorithm produces a new set of voltage and sends it to the mirror so as to optimize its shape, in such a way, as to maximize the strength of the photodetector current in the imaging system. In this paper the results of the application of three optimization techniques in the sensor-less AO are compared. The three optimization techniques are simulated annealing (SA), genetic algorithm (GA) and particle swarm optimization (PSO). SA and GA have been previously implemented and PSO is explained in this paper

What is the effect and mechanism of kinesiology tape on muscle activity?

Objective: This study aimed to evaluate the effects of kinesiology tape, anesthesia, and kinesiology tape along with anesthesia, on motor neuron excitability. Participants: Participants included 20 healthy men aged 20�35 years, who were examined over 5 sessions. Intervention: The five experimental sessions included: control without applying the kinesiology tape or Eutectic Mixture of Local Anesthetics (EMLA); treatment only with EMLA; only kinesiology tape application; only sham tape application; and treatment with kinesiology tape and EMLA. Main outcome measures: The H-reflex recruitment curve of the soleus and lateral gastrocnemius was recorded by a blinded assessor in the 5 separate sessions randomly assigned with 48 h washout periods. The major H-reflex parameters include: the Hmax/Mmax ratio, the H-reflex threshold stimulation intensity (Hth), the intensity of maximum H-reflex (IntensityHmax), the H-reflex ascending slope (Hslp), and the H-reflex ascending slope fixed into the first three points (first Hslp). Results: The H-reflex parameters (H slope, first Hslp, Hth, and IntensityHmax) were facilitated by application of the kinesiology tape with and without EMLA; however, EMLA inhibited the H-reflex parameters (Hmax/Mmax ratio, Hslp, first Hslp, and Hth) in both the soleus and lateral gastrocnemius. The sham tape did not alter the H-reflex recruitment curve parameters. The statistical model revealed a significant difference between the kinesiology tape and the sham tape and control sessions, between kinesiology tape�EMLA and EMLA, and between kinesiology tape�EMLA and control session. Conclusions: Results suggest that the kinesiology tape facilitates the muscle activity and the underlying mechanism on the gastrosoleus motor neuron pool involves the cutaneous receptors. © 2017 Elsevier Lt

Situational awareness architecture for smart grids developed in accordance with dispatcher's thought process: a review

The operational environment of today’s smart grids is becoming more complicated than ever before. A number of factors, including renewable penetration, marketization, cyber security, and hazards of nature, bring challenges and even threats to control centers. New techniques are anticipated to help dispatchers become aware of the accurate situations as they manipulate and navigate the situations as quickly as possible. To address the issues, we first introduce the background for this topic as well as the emerging technical demands of situational awareness in the dispatcher’s environment. The general concepts and technical requirements of situational awareness are then summarized, aimed at offering an overview for readers to understand the state-of-the-art progress in this area. In addition, we discuss the importance of integrating the architecture of support tools in accordance with the dispatcher’s thought process, which in fact guides correct and swift reactions in real-time operations. Finally, the prospects for situational awareness architecture are investigated with the goal of presenting situational awareness modules in an advanced and visualized manner
