- چکیده انگلیسی: Introduction: E-learning can result in the promotion of efficiency in the educational processes. However, the development of E-Learning may fail to succeed if the users’ attitudes are not considered. The users’ attitudes are very effective in the adoption and use of E-learning. The purpose of this study was to determine the attitudes of faculty members of Kermanshah University of Medical Sciences on E-Learning.Materials and Methods: This cross-sectional study was conducted, using a stratified proportional random sampling. The participants consisted of the faculties members of Kermanshah University of Medical Sciences. The instrument for data collection was a researcher made questionnaire based on similar studies in two parts: part one with eleven background items, and part two with twelve attitude items. The validity of the questionnaire was approved, using experts’ comments and the reliability was found to be 0.73, using Cronbach's Alpha test. The collected data were analyzed by SPSS-21, using independent T-tests and ANOVA with α=0.05.Results: Maximum scores were 47.23 percent of the total score. Three items, “saving the students’ time”, “solving many problems of teaching” and “saving the teachers’ time” achieved the highest mean score, respectively. Only the faculty members with experience in E-learning education had better attitudes (p=0.003).Conclusion: The attitude of faculty members of Kermanshah University of Medical Sciences toward e-learning was not appropriate. Holding workshops in the field of E-learning by EDC can help to improve the condition.

- چکیده انگلیسی: The statistical modeling of social network data needs much effort because of the complex dependence structure of the tie variables. In order to formulate such dependences, the statistical exponential families of distributions can provide a flexible structure. In this regard, the statistical characteristics of the network is provided to be encapsulated within an Exponential Random Graph Model (ERGM). Applying the ERGM, in this paper, we follow to design a statistical process control through network behavior. The results demonstrated the superiority of the designed chart over the existing change detection methods in controlling the states. Additionally, the detection process is formulated for the social networks and the results are statistically analyzed.

- چکیده انگلیسی: The aim of this work theoretical study is to theoretically investigate a inorganic membrane assisted purifcation process of an H2-rich stream derived from a conventional methanol steam reforming stage. In particular, a black-box model for multicomponent gas mixture purifcation is developed to evaluate the H2 separation performance of such non-palladium based membranes such as silica, polymeric and carbon membranes, by varying design and processing variables such as stage cut and feed pressure. The most signifcant modeling result is achieved by using a silica membrane based separation module in which 98% of H2 purity and 0.3% of carbon monoxide in the permeate side are reached, operating with a transmembrane pressure of 4.0 bar.

- چکیده انگلیسی: Background: Some members of family Calliphoridae are myiasis agents and mechanical vectors of some pathogens. The aim of this study was to measure the biodiversity and synanthropy behaviour of Calliphoridae flies in Abadan, Khuzestan province. Methods:Data were collected based on a monthly schedule during March to December 2014 in urban, semi-urban and rural ecosystems of Abadan County. Bottle trap was equipped with 30 g of chicken liver and installed 3 days in each collection site where net collection was done for about 30 minutes. Synanthropy Index (SI) of flies and biodiversity indices including Simpson, Shannon-Wienner and Margalef were calculated. Results: As many as 1479 samples of Calliphoridae were collected including 18, 1212 and 249 specimens of Chrysomyia megacephala, C. bezziana and C. albiceps respectively. C. bezziana showed a moderate SI in some collecting times. In spite of more collection of C. megacephala in all three ecosystems, its SI had the highest range in comparisons with the others. The biodiversity of Calliphoridae community was high in spring (H´= 0.67) while the highest diversity of dominant species was in autumn (1-D = 0.74). Margalef Index showed equal estimation of species richness in spring and autumn (Mg = 0.3) but it was reduced in summer. Conclusion:C. megacephala was the common species of Calliphoridae in Abadan. Abadan is an old international county in Iran which is the host of many domestic and international engineers, workers and visitors. Knowing the fauna and behaviour of medically important flies would be a major fact for the conditions of the health status of this city.

- چکیده:
- چکیده انگلیسی: Background:Anopheles maculipennis complex species is considered as one of the most important species complexes with 12 species and significant role in the transmission of important diseases such as malaria, lymphatic filariasis and multiple Arboviral infections. The aim of the present study was to analyze Internal Transcribd Spacer (ITS) 2 fragment among Anopheles maculipennis species complex in West Azerbaijan Province, Iran and also to identify different species of An. maculipennis using ITS2 fragment. Methods:Adult and larval specimens of different mosquitoes’ species were collected from the northern, southern and central parts of West Azerbaijan Province. Adult mosquitoes were collected using standard methods of indoor and outdoor hand catch, human and animal bait and light traps. Also larvae were caught using dipping method during May- Sep 2016. After DNA extraction, ITS2 fragment was amplified and analyzed using Bioinformatics tools. Results:Totally, 271 specimens belonged to Genus Anopheles [158 samples of An. maculipennis (adult: 50, Larvae: 57), 101 An. claviger (adult: 21, larvae: 80) and 12 specimen of An. superpictus (adult: 3, larvae: 9)] were collected from different parts of the province. Also, the presence of at least two species of Anopheles maculipennis species complex (An .maculipennis and An. Persiensis) was concluded. Conclusion: Based on the reported differences between these species, accurate identification of these species in terms of their ecology, vectorial capacity and their insecticide resistance profile is recommended. Also, other molecular markers such as COI, should be examined for better resolution of species composition in An. maculipennis.

- چکیده انگلیسی: Objective(s): Neuroprotective effect of creatine (Cr) against β-amyloid (Aβ) is reported in an in vitro study. This study investigated the effect of Cr supplementation on β-amyloid toxicity in vivo. Materials and Methods: Thirty two, male Wistar rats were divided into 4 groups. During ten weeks of study, control group went through no surgical or dietary intervention. At the 4th week of study Sham group had a hippocampal normal saline injection, while Aβ and AβCr groups had an β-amyloid injection in the hippocampus. AβCr group were fed by Cr diet during the study. After 10 weeks, Morris water maze (MWM) test was administered to measure learning ability and memory retrieval. Animals were sacrificed for TUNEL anti apoptotic assay and staining of amyloid plaques by Thioflavin-T. Results: There was a significant retention deficit among AβCr and Aβ group while the escape latency and the distance traveled to the platform were significantly higher in AβCr group compared to Aβ group. AβCr group had same percent of TUNEL positive neurons compared to Aβ group. Conclusion: Cr supplementation before and after β-amyloid injection into the CA1 area of hippocampus deteriorates the learning and memory impairment of rats and it does not protect neuronal apoptosis caused by β-amyloid.

- چکیده انگلیسی: Background
Children are more likely to be burned than other age. The aim of this study was to determine the burn-related factors in children in Kermanshah province, Iran.
Materials and Methods
In the present hospital based case-control study, 198 under 15 years age children who were burned ( from beginning of spring 2016 until the end of spring 2017), enrolled into the study as cases and 198 children referred to the hospital for non-burning reasons selected as controls. The cases and controls were frequency matched for age and gender variables. Principal Component Analysis test was used to construct the socioeconomic variable and univariate, moreover multivariate logistic regression tests were used to determine the burn-related factors. All analyses were carried out using SPSS software version 21.0.
Results: The mean age of children with burns was 4.3 ± 3.5 years. The most common factor of burns was hot liquids with 48.5%. Body mass index (Odds Ratio (OR)=1.252, P= 0.004), number of household members more than 5 body (OR=8.472, P<0.001), absence of more than one watchful (OR=2.481, P=0.026), hours without watchful (OR=8.649, P<0.001), illiterate mother (OR=9.778, P=0.002), petroleum storage at home (OR=1.815, P=0.046), and the lowest quartile of socioeconomic level (OR=7.220, P<0.001) increased the chance of burning in children. Increase of mother age (OR=0.938, P=0.005) and the worker father (OR=0.233, P=0.002) reduced this chance.
Conclusion: Based on results of current study, burning in children is a multifactorial outcome including individual, social and environmental factors such as Body mass index, household size, mother age, father job, less watchful, hours without watchful, illiterate mother, petroleum storage at home, and socioeconomic status.- انتشار مقاله: 14-10-1396

- چکیده:
- چکیده انگلیسی: Background: Burn is one of the public health problems, especially in low-income and middle-income countries, and this problem is far more important for pregnant women and their fetus. There was no a systematic study to comprehensively review the epidemiology of Maternal and Fetal`s Burn inIran, this study was conducted for this purpose.
Materials and Methods: In this systematic review and meta-analysis study, all related studies (Published in 2017 and earlier) extracted by two independent groups from national and international databases (Magiran, SID, Web of Science, Medline, Scopus, etc.). Meta-analysis has been applied to obtain the overall outcomes of maternal and fetal mortality in pregnant women in Iran. Forest plot, τ2, and I2 tests are applied to evaluate heterogeneity, significance and its percentage, respectively. The analysis of meta-regression is applied because of the existence of heterogeneity. Publication bias is investigated by Funnel plot and Egger test.
Results: The range of maternal and fetal mortality was 29.2% to 66.67% and 38.5% to 72.8%, respectively. Also, 48.4% and 54.2% were the overall outcome of maternal and fetal mortality based on meta-analysis, respectively. The highest maternal mortality is reported for pregnant women with Total Body Surface Area (TBSA) over 50%, intentional burns, and acute respiratory failures. Finally, reduction of maternal mortality had a statistically significant relationship with passing time based on the univariate analysis.
Conclusion:It can be inferred from our results that some hazards of burn in pregnant women are average age of 22-27 years, living in rural areas, low levels of socio-economic, low education level and being housewife. Also, according to meta-analysis results, about half of mothers and fetuses died in pregnant women as a result of burns in Iran.- انتشار مقاله: 05-10-1396

- چکیده:
- چکیده انگلیسی: Objective: The prevalence of burn in children is more than other age groups. This study aimed to "investigate the factors associated with the burn degree and total body surface area (TBSA) in under five-year-old children of Kermanshah ".
Methods: We studied under five-year-old children hospitalized in the burn center of Imam Khomeini hospital in Kermanshah from September 2014 until March 2016 for 18 months. Required Information extracted by trained staff based on existing data. Researcher-made checklist was used to obtain information. The ordinal regression has been applied to evaluate factors related to TBSA and burn degree in children.
Result: In general, 262 children were input of the study so that 226 cases (86.3%) were in under two-year-old group. The majority of cases were boys by 66.8% (175 cases). Hot liquid was the most reported cause of burns by 68.7% of all cases. Most of the burn incidents (43.1%) with high burn degree occurred at 7 am to 2 pm. Girls were exposed to higher burn degrees more than boys. Factors such as being boy (OR=2.83), less than 2 years old age (OR=4.91) significantly increased TBSA. Also, living in rural (OR=5.17) and delay of treatment (OR=41.35) significantly increased burn degree.
Conclusion: To reduce the incidence and complications of burns in children, interventions should be considered to change the environmental and individual factors.- انتشار مقاله: 13-09-1396

- چکیده انگلیسی: Breast cancer is the most common cancer among women. The present study investigated the stage of breast cancer
screening adoption and the role of some of the cognitive predictors in a sample of Iranian married women. There were
a total of 334 married women clients of eight health centers in Kermanshah city, the west of Iran, were randomly
selected to participate voluntarily. Women filled out a self-report questionnaire. Data were analyzed by SPSS version
20 using One-way ANOVA, χ2-test, Fisher’s exact test, and bivariate correlations statistical tests at 95% significant
level. The mean age was 39.75 years [SD: 7.73]. Nearly 58.4%, 26.9%, 3%, 9.6%, and 2.1% of the respondents were
reported pre-contemplation, contemplation, preparation, action, and maintenance of breast cancer screening adoption,
respectively. There was a significant association between age (P=0.005), and positive family history of breast cancer
(P=0.037), perceived susceptibility (P=0.005), perceived severity (P=0.001) and knowledge of symptoms (P=0.018)
with breast cancer stage of screening adoption. Our findings can provide better knowledge for the development and
implementing of stage-targeted breast cancer screening adoption promotion programs. We conclude that it seems that
the focus of health planner should be to rise to perceived severity; perceived susceptibility and knowledge of symptoms
of breast cancer about the promotion of breast cancer screening adoption an Iranian woman.- انتشار مقاله: 13-12-1397
