In smart schools, information and communication technologies are accompanied with a comprehensive and holistic model, entering predetermined goals and missions into the field of education. The present study aimed at exploring the challenges and strategies in the use of ICT to smartize schools. Methods A qualitative approach was adopted in the present study in conducting interviews with 3 focus group experts (faculty members, teachers, and specialists in educational technology) in the city of Sanandaj. Semi-structured interview was used for data collection. Criterion-based purposive sampling method was used to study the experts ‘viewpoints (4 faculty members, 7 experienced teachers, and 4 experts of information and communication technology in education). In addition, thematic content analysis was used to encode data and summarize the interviews. Finally, strategies were developed using the environmental analysis of SWOT. Results The findings suggested that smartization of schools have noteworthy strengths. These strengths are as follow: encouraging active learners, developing the identity of students, offering opportunities for interactive learning in educational settings, and promoting qualitative development of education. The weaknesses of school smartization process were insufficiency of specialized human resources, incorrect culture in use of ICT tools, and certain challenges (weakness in policymaking, ICT development strategies, and disruption of structural and infrastructure-related factors. Conclusions Fundamental contributive steps could be taken by minimizing weaknesses and challenges, maximizing strengths and opportunities for smart schools, and adopting appropriate strategies for smart schools by experts.

- چکیده:
- چکیده انگلیسی: Three-dimensional reconstruction of objects is one of the key elements in production processes. Stereo vision is one of the robost techniques in this field. Accuracy of the reconstruction is influenced by several parameters that mainly determined through the calibration process. Besides, symetring of two accquired images effects on the accuracy. In the present research, a three-dimensional model reconstruction system based on stereo vision technique included a camera, a robot, a lightening system, a cubic object, and IMAQ Image Processing and LabVIEW Softwares. The inactive stereo vision was considered such that the images were acquired by the same camera in two different positions. The cuboid model was implemented after camera calibration. The corners of the object were considered to remove the symmetry problems. After comparing the dimensions of the reconstructed model with those of real objects, the maximum error value of the system was obtained as 0.75 mm and the error variance as 0.09 mm.

- چکیده:
- چکیده انگلیسی: Sarabi cattle are found in Iran and Azerbaijan. They are used for both dairy and meat production. A histological study was carried out on the teat of Sarabi cattle for the first time in Iran. A total number of five adult and healthy cows were selected and after slaughtering, tissue samples were taken from different parts of the teat skin. After fixation in 10% formalin, they were transferred into the tissue processor. Paraffin blocks were made and thin sections of 6µ, were cut. The sections were subjected to stain by Hematoxylin and Eosin. They were studied under the light microscope and photo micrographs were taken. The results show that the teat consists of teat sinus, teat wall, teat canal and teat orifice. Teat wall includes three separable strata: skin, middle layer and mucosal layer.Teat skin contains an epidermis and dermis, but there is no evidence of hypodermis existence in contrast with the other parts of the body. Dermis is formed from networks of collagen fibers, blood vessels, circular smooth muscle and nerve fibers. Meissner’s corpuscles are found in the dermal papillae particularly in the connective tissue of teat canal. Myelinated nerve fibers are also seen in this region.

- چکیده:
- چکیده انگلیسی: Rutilus frisii kutum is a cyprinid fish, distributing along the Caspian Sea, from Atrak River (Turkmenistan) to Kura River (Azerbaijan). This fish is one of the commercially important fishes in the south of the Caspian Sea. This species is normally a medium-sized fish, typically reaching 45-70 cm in length, weighing up to 5 kg. The kidney of the vertebrate is the main organ which balances the body fluid homeostasis. A histological study was carried out on the nephron of Rutilus frisii kutum for the first time. A total number of ten adult fish from the southern Caspian Sea fishing region were subjected to this investigation. The kidneys were removed and immediately fixed in 10% buffered formalin for 24 hours. Then, they were transferred into the tissue processor. Paraffin blocks were made and thin sections of five microns were cut. The sections were subjected to staining by Haematoxylin & Eosin. They were studied under the light microscope and photomicrographs were taken. The different parts of nephron were renal corpuscles, two types of proximal convoluted tubules, an intermediate segment and collecting ducts. There were no evidence for distal convoluted tubules and henle loops.

- چکیده:
- چکیده انگلیسی: Urinary tract infections are one of the most common infectious diseases that lead to significant health problems in the world. Urinary tract infections are referred to any infection in any part of the renal system. Uropathogenic Escherichia coli, Proteus mirabilis, and Klebsiella are main organisms that are involved in these infections.
After identifying same protective and conserved virulence sequences in these microorganisms with similarity upper than 80%, sequences of synthetic gene was provided by bioinformatics techniques and ordered from Thermo Fisher Scientific Company. PCR amplification of this gene was performed by specific primers designed for this purpose. Construction of gene was performed by overlap PCR. The synthetic gene was cloned into pET28a vector. Our gene was amplified in E. coli Top10 tested.
To confirm cloning, three methods including colony PCR, digestion and sequencing were used. First, two techniques were performed using horizontal electrophoresis, and also the synthetic gene showed significant homology with the sequence (99% Identified) in sequencing. Sequencing of this gene showed that fusion was constructed correctly. Determination of biochemical properties such as 3D structure, Ramachandran and comparison of Non-redundant Set of PDB structure was done by bioinformatic software and had exact and expectable results.
A large part of the health system in the world is occupied by a urinary tract infection and governments spend a huge amount of money for the treatment and recovery of patients with these infections. On the other hands, antibiotic resistance in the not-far future will be a disaster for medical societies. This is the most important reason for the emergence of vaccine production against urinary tract infections.- انتشار مقاله: 30-05-1396

- چکیده:
- چکیده انگلیسی: Background & Aims: Assessment of physical growth is one of the most important methods of determining nutrition and health status. Body mass index (BMI) is a suitable index for growth monitoring and helpsin the identification of growth disorders and malnutrition in teenagers. The aim of thisstudy wastodetermine BMI statusin secondary school studentsin Kerman, Iran, in 2012. Methods: This was a descriptive-analytic study in which data were collected cross-sectionally and compared with the results of the study in 1997. After gaining permission from the Department of Education of Kerman, the samples were selected randomly from the secondary schoolsin Kerman. Height and weight were measured by standard tools. Data were analyzed through SPSS software and using Students' independent ttest. Results: Mean BMI of the students(n = 424) was 19 ± 4.2 and 44.8% ofstudents had normal BMI. Mean BMI of boys wassignificantly lower than girls. In total, 6% of the students were excessively thin and they were mainly from public schoolsin the suburb of the city. Over 50% ofstudents had weight problems; underweight wasthe main problem in the studied population and only 9.2% of oursubjects were overweight. Conclusion: Since the pubertal height and weight growth spurt occurs earlier in girls(10-13 years) than boys, the absolute comparison of BMI based on sex is not wise; if necessary itshould to be performed after this period. Malnutrition or lack of accessto food, or cultural factors and body shape care could explain our findingsin regard to the distribution of BMI in the student population of Kerman.

- چکیده: زمینه مطالعه: کوکسیدیوز به عنوان یک بیماری انگلی که بیشترین تأثیر اقتصادی را بر تولید طیور دارد، شناخته شده است. صنعت مدرن پرورش طیور به میزان زیادی وابسته به ترکیبات ضد کوکسیدیوز است. هدف: مطالعه حاضر جهت تعیین و مقایسه کارایی دو ضد کوکسیدیوز شیمیایی (کلوپیدول و دیکلازوریل) بر دفع اووسیست و همچنین اثرات احتمالی آنها بر عملکرد پرورشی و کارایی تغذیهای طیور گوشتی در کوکسیدیوز تجربی انجام شده است. روش کار: تعداد 120 قطعه جوجه یک روزه نژاد Ross 308 بطور تصادفی گروهبندی شدند: کنترل مثبت؛ آلوده به کوکسیدیوز بدون درمان، گروه کنترل منفی؛ بدون آلودگی و بدون درمان، گروه CLO؛ آلوده و درمان شده باکلوپیدول، گروه DIC؛ آلوده و درمان شده با دیکلازوریل. برای ایجاد کوکسیدیوز تمامی گروهها بجز کنترل منفی با اووسیست اسپوروله عفونی در انتهای هفته سوم تلقیح شدند. میزان دفع اووسیست با استفاده از لام مک مستر شمارش گردید. وزن بدن، وزنگیری و ضریب تبدیل غذایی هر هفته اندازهگیری و محاسبه گردید. نتایج: شمارش اووسیست نشان داد که دیکلازوریل در کاهش تعداد اووسیست کارآمدتر از کلوپیدول بود. میانگین وزن بدن در گروه کنترل مثبت از سایر گروهها پایینتر بود. ولی در انتهای مطالعه میانگین وزن در گروههای درمان شده با کلوپیدول و دیکلازوریل با گروه کنترل مثبت تفاوت معنیداری را نشان نداد. در مقایسه وزنگیری میان گروههای مختلف بجز در هفته چهارم و پنجم در سایر هفتهها تفاوت معنیداری مشاهده نشد. بر پایه نتایج بدست آمده از FCR اضافه نمودن ترکیبات آنتی کوکسیدیال اثر معنیداری بر بهبود آن نداشت. نتیجهگیرینهایی: گزارش شده است که برخی از ترکیبات ضدکوکسیدیوز منجر به کاهش مصرف خوراک و ضریب تبدیل غذایی میشوند. به نظر میرسد هیچکدام از ضدکوکسیدیوزهای شیمیایی مورد استفاده در مطالعه حاضر در کنترل زیانهای اقتصادی کوکسیدیوز به طور کامل مؤثر نمیباشند و ارائه استراتژیهای جدید مورد نیاز میباشد.
- چکیده انگلیسی: Background: Coccidiosis is recognized as the parasitic disease that has the greatest economic impact on poultry production. Modern poultry production is largely dependent upon anticoccidials. Objectives: The aim of the present study was to determine and compare the efficacy of two chemical anticoccidials (Clopidol and Diclazuril) on oocyst shedding and their probable effects on growth performance and feed efficiency of broilers in experimental coccidiosis. Methods: One hundred and twenty Ross 308 one day old broilers were randomly assigned into 4 groups: CON+, infected with Eimeria mixed oocysts but not medicated; CON-, not infected and not medicated; CLO, infected and medicated with Clopidol; DIC, infected and medicated with Diclazuril. Chickens in all groups except negative control were inoculated by mixed sporulated oocysts of pathogenic Eimeria at the end of the 3rd week of age. Oocyst shedding was counted using a Mc Master counting chamber. Body weights, body weight gains, and feed conversion ratio were determined on weekly basis. Results: Obtained results showed that Diclazuril was more effective in reducing oocyst shedding than Clopidol. As expected, mean body weight in the positive control group was lower than other groups. But surprisingly, no significant difference was found between Diclazuril or Clopidol treated birds and positive control group, at the end of the experiment. In comparison of weight gain in different treatment groups except for the 4 and 5th week, no significant difference was found in different groups. In the last week of the experiment, difference in weight gain between groups was not significant. According to feed conversion ratio (FCR) results, anticoccidial supplementation did not have any significant effect on improving FCR. ConclusionS: It is reported that some anticoccidials reduce feed consumption and feed conversion. It seems that neither of the present synthetic anticoccidials is completely satisfactory in controlling coccidiosis economic losses and new strategies are urgently required.
