Today, due to the high speed of information transmission, the use of electronic learning methods such as infographics and educational videos, is a necessity for optimal training of the audience. This study endeavors to compare the views of paramedical students of Kurdistan University of Medical Sciences on two methods of infographic and short video electronic learning for airway obstruction

The population for this descriptive-applied study includes 420 students of paramedical faculty who were members of the faculty's information social network channel. 118 of them completed the relevant questionnaire after viewing both contents. The instrument was a 22-item questionnaire on the effectiveness of electronic education by Shabani et al. Data analysis was done using descriptive statistics and chi-square test.

The results revealed that from the learners' view, regarding the effectiveness of electronic learning, the content of the infographic was effective (sig =.000) and the educational video (sig =.102) was not effective. Regarding the percentage of students' satisfaction with infographics and movies and the questions, the minimum time spent to understand the concepts is 78% and 67%, increasing the level of knowledge after using the content is 84.7% and 75.4%, the satisfaction of the entire content is 79.6% and 78.6%.

The content of the infographic was effective in the reaction level of the Crick Patrick model; however, the use of the educational video was not effective. It is suggested that the use of electronic education and small contents and the use of images instead of long text, which has high effectiveness and greater acceptance in today's society, should be used by students under the surveillance of professors.

Education in medical sciences also needs a fundamental change in order to improve the level of education by using modern teaching methods. Using videos during teaching makes students more alert and more motivated and focused on the subject. Since Mashhad University of Medical Sciences is one of the mother universities of the country and the center of educational technology and according to the listed advantages, a study was designed to design, implement educational topics in the form of videos and in the theory classroom for laboratory science students. To be displayed.

 44 laboratory science students were considered as the target group and participated in this scholarly study. The film was designed at the University Study Center and in the classroom, pre-test students consisting of 4 four-choice questions were first taken and the film was screened and then the test post was taken. At the end of the second session, a survey form consisting of 9 questions was given to the students and finally the test and survey results were analyzed with SPSS 21.

 The correct questions answered in the post-test were more than the pre-test, which was a significant level for the first question (p = 0.03) and the next three questions (p <0.001), respectively. Also, the number of wrong questions answered in the post-test was significantly reduced (p <0.001). Surprisingly, almost 80% of students expressed little or no interest in continuing this teaching process.

Despite the fact that the students' scores in the post-test were significantly better than the pre-test, but most students expressed little or no interest in continuing the teaching process using the film.

Nursing is a profession that requires a positive view of society and governments for growth and excellence. Providing a distorted or populist image of the profession can have negative consequences for health care providers. This article aims to explain the image of nurses in Iranian cinema in the last three decades.

This content analysis study was conducted in 1398 in Semnan University of medical science on 16 Iranian cinema and television films using the researcher-made checklist and was evaluated in three time periods of the 1991s, 2001s and 2011s. Content analysis of selected movies was performed based on a three-step myring method (summarizing, clarifying and structuring).

Most of the films reviewed in each of the three decades were socially thematic, with superpowers playing the role of all the portrayed nurses in the 1970s, while none of them were superstars in the next two decades. Most of the nurses that portrayed in these films were young and gradually, over the course of three decades, the marital status of nurses changed from unmarried to single. Also, the nature of the majority of works that provided by nurses over a three-decade period, ranged from the specialized to the non- special work

Depiction a scientific and accurate picture of the nurse and nursing practices in the films of the three decades under review has not a good progress and nurses have been involved in role stereotypes.Magnifying features such as female gender, celibacy, youth and inappropriate appearance of nurses and playing unprofessional roles that seen in the examined films, can perpetuate the societychr('39')s incorrect stereotypes of nursing that require correction.

Currently, panoramic radiography is very popular with dentists due to its proper cost and low radiation dose in terms of the data it provides. During the diagnosis and treatment process, a dentist should keep himself and the patient safe from the dangerous effects of ionizing radiation during radiography. Therefore, this study was undertaken to present a guideline for dentists and technicians for better patient protection. Materials &

In this cross-sectional, descriptive/analytical study, 4 calibrated TLDs were placed in appropriate positions within a holder and placed on the surface of a lead apron on the anterior and posterior aspects. One TLD was also placed in the environment as a control. One hundred patients, candidates for taking panoramic radiographs, wore the lead apron and underwent conventional panoramic radiography. Then the TLDs were sent for processing and the results were analyzed with repeated-measurements ANOVA, post hoc least significant difference, one-sample t-test and paired-samples t-test (α = 0.01).

TLDs that had undergone radiographic exposure 100 times showed the absorbed dose in millisievert unit. Skin dose on the postero-superior region (0.31) was the highest amount measured, followed by the absorption dose on the postero-inferior region (0.28), antero-inferior region (0.22), antero-superior region (0.19); the control TLD which was placed outside the room showed insignificant absorption dose.

In this study, the patients’ radiation doses were separately reported for the anterior and posterior mid-body regions. The skin absorbed dose in the posterior mid-body region was higher in comparison with the anterior region. Therefore, it is advisable for the patients to wear the lead apron like a coat on the posterior region.

Teachers 'educational behavior is one of the most important factors influencing students' teaching and learning process and its continuous evaluation ensures improvement of the quality of teachers' performance and educational activities.

Initial questions about teaching quality assessment included 36 questions. Finally, 24 questions were presented in four domains including non-verbal communication (9 questions), verbal communication (4 questions), interacting with students (6 questions) and classroom management (5 questions). At the validation stage, all 24 questions had acceptable content validity (0.7 to 1.0). The reliability of the instrument was confirmed by the Kappa coefficient (0/8). The Instrument designed to evaluate the quality of teaching based on film, has acceptable validity and reliability.

Due to increasing food production, it seems necessary a healthy and appropriate food delivered to consumers. One of the most important reasons for packaging is to prevent the growth of spoilage and pathogenic microorganisms in food. The aim of this study was to investigate the effect of polylactic acid (PLA) films containing different concentrations of cumin essential oil on some microbial and chemical characteristics of minced beef meat.
In order to study the antimicrobial effect of PLA films containing different concentrations of cumin essential oil, samples were examined for total aerobic bacterial count, psychotropic bacteria, coliform and Staphylococcus aureus at different times, day 0, 1, 2, 3, 4, 6 and 8. In order to study the effect of films on total volatile nitrogen (TVB-N) of minced beef, the intended tests, were conducted on the same days of the microbial tests.
The results of the present study indicated that total aerobic bacterial count, psychotropic, coliforms and S. aureus in samples packed with PLA films containing 0.8% cumin essential oil were significantly lower than control group (P Based on our findings, the use of PLA films containing 0.8 % concentration of cumin essential oil could be a good method to keep minced meat during cold storage at least 8 days without any significant microbial and chemical spoilage.

According to the research background and need to print CBCT images in case of emergency, this study has been done to compare to quality and accuracy of the two methods of film and paper printing for CBCT images.
The study of CBCT images taken from 5 patients was done. cross-sectional slices on Fotolusio DNP papers and film AGFA were printed. Afterward, images by maxillofacial radiologist was exmined. Images’ quality were identified and recorded with anatomical, from 1 to 4 on forms. The accuracy was determined by the diagnosis of alveolar canal area and the comparison with the Gold Standard. In order to analyze, the independent chi-square and Fisher exact tests’ results were used.
The Images quality in anatomical landmarks consisting PDL (P=0.02), lamina dura (P=0.006), the inferior alveolar canal (P=0.01) and the filling (P=0.006) had a significant difference. For the lower border of the mandible Landmark, there was no difference between the two methods of printing. In comparing the diagnostic accuracy between the two methods there was no significant difference (P=1).
The diagnostic quality in film printing is better than paper printing and the diagnostic accuracy is the same in both methods.

Most of patients that refer for angiography do not have enough information about the procedure; this lack of knowledge makes the patients dissatisfied. Accordingly the aim of this study was investigating the effect of video education based on patients’ native language on knowledge and satisfaction of patients hospitalized for coronary angiography. In This quasi experimental study, 160 patients were randomly assigned into two control (n=80) and experimental (n=80) groups. These patients were selected among all the patients who came for non-emergency coronary angiography for the first time in the Thoracic Department of Medical-Educational Center of Imam Khomeini in 2013. For the experimental group, an educational film about the coronary angiography was presented. And for the control group, the routine actions of the ward were presented. The awareness level of the patients in both groups was measured after and before education by using a researcher-made awareness questionnaire. And the satisfaction level of the patients in both groups was measured after education by using a researcher-made satisfaction questionnaire. Data was analyzed by SPSS13 software with using chi-square test, independent t-test and paired t-test. After the intervention, the mean of satisfaction in the experimental and control groups was respectively; 41.20 and 23.95 and the mean of awareness was respectively; 15.81 and 6.81; the experimental group in both dimensions (p =0. 001) was better than the control group. Results of this study confirm the efficiency of video education based on patients’ native language in increasing knowledge and satisfaction of the patients candidate for coronary angiography. Therefore, the video education is recommended for educating these patients.

Dermal and transdermal delivery of drugs are difficult due to the barrier properties of the stratum corneum. Polymeric carriers such as chitosan can be used to increase drug permeability. Chitosan is a nontoxic natural cationic biopolymer and has been widely used in biomedical field including healing burns and wounds owning to its biological properties such as biocompatibility، biodegradability، mucoadhesivity، antibacterial and hemostatic activities. This polymer can be used to produce dermal/transdermal preparations in different types of drug delivery systems including hydrogel، film and nanoparticle. The aim of this review article is introduce chitosan as a carrier for dermal and transdermal drug delivery.

A large number of non-recyclable packaging materials، which are harmful for the health of consumers، are produced all over the world. The Suggested solution is using films and coatings which are biodegradable in nature. Pullulan is a biopolymer that is produced by Aureobasidium pullulans and used in order to produce edible films. These edible films could contain antioxidant and antimicrobial agents. The primary aim of this study is to produce edible blended films that form pullulan whit Artemisia sieberi essential oil and the secondary goal is to investigate the antimicrobial attributes of the obtained film. The Essential oil of Artemisia sieberi was added to the solution of pullulan films in seven concentrations. Then، the antimicrobial attributes were determined with the dick diffusion method. Finally، minimal inhibitory concentration was calculated for each microbe. The SAS program (Version 9. 1) was used for the completely randomized design of data analyses. It is possible to produce pullulan film containing Artemisia sieberi essential oil. Escherichia coli and Staphylococcus aureus had maximum and minimum resistance towards the antimicrobial attributes of Artemisia sieberi essential oil، respectively. MIC of Artemisia sieberi essential oil against Staphylococcus aureus، Lactobacillus plantarum and Escherichia coli were respectively obtained at 15%، 10% and 15%. Due to the possibility of the production of biodegradable films with the addition of natural antimicrobial agents such as essential oils it can be concluded that it is appropriate to use these materials in order to decrease microbial load and increase the shelf life of foods.
