Abstract: Introduction: In the recent years, organizational culture has been an important research concept in the management domain. This study intends to determine the organizational culture of Hamadan University of Medical Sciences form the view point of faculty members based on Hofstede Model.Material and Methods: In this cross-sectional descriptive-analytic study, faculty members of Hamadan University of medical sciences were research population that sample involved 162 people which have been selected through random sampling. To gather the data, Hofstede Organizational Culture Questionnaire was used as well as demographic variables questionnaire. To analyze the data SPSS was used.Results: The sample consisted of 63.59% male. The mean age of the sample was 36.45 (SD:4.35) and the mean years of employment was 16.43 (SD:5.77). 34.573% were lecturer, 52.47% assistant professor and 12.86% associate professor. The findings revealed the characteristics of the organizational culture of the research population as follows: cultural balance with a trend to masculinity, collectivism, low uncertainty avoidance and relatively balanced of power distance. Also factors such as age and years of employment have negative significant relation with uncertainty avoidance and masculinity-femininity rate in the man and women are different.Discussion: Faculty members in Hamadan University of Medical Sciences consider organizational culture supportive and they believe that University beside being emphasized over the social responsibilities, tends to avoid injustice.

Abstract: Background/Objective: Evaluation of educational programs is very important in the process of programming. Evaluation is a comparison between educational results and predetermined goals in order to make decision about programs. Via evaluation, one can judge about programs and of course can correct or change them if necessary. "nMaterials and Methods: In this study, the degree of fulfillment of educational goals for radiology students in technology has been evaluated from 1385 to 1386 by distributing questionnaires among these students. The relationship between fulfillment of educational goals and scores of students in different semesters were evaluated by statistical analysis. "nResults: About 24%, 96% and 100% of students of semester 1, 2 and 3 completely answered the ques-tions and the others were excluded from the study. About 79.3% of the first semester students of radiology assessed a medium fulfillment of educational goals, but in one case, public health lesson, most of them (64%) believed in low fulfillment of goals. Second semester students of radiology, as the same ratio, assessed the fulfillment of goals as high, medium and low. Most of the third semester students (60.3%) believed that the fulfillment of educational goals had been medium. Most of students believed that the degree of fulfillment of educational goals of courses taught by professors who were not members of the school was higher. There was no statistically significant relation between the fulfillment of educational goals and the score of students in related lessons. "nConclusion: The study revealed that the degree of fulfillment of educational goals for students in different semesters of Radiology was different. There were significant differences between fulfillment of educational goals in theoretical courses conducted by groups inside and outside the paramedical school.

Abstract: Introduction: Today, with the tremendous potential of genomics and other recent advances in science, the role of science to improve reliable DNA extraction methods is more relevant than ever before. The ideal process for genomic DNA extraction demands high quantities of pure, integral and intact genomic DNA (gDNA) from the sample with minimal co-extraction of inhibitors of downstream processes. Here, we report the development of a very rapid, less-hazardous, and high throughput protocol for extracting of high quality DNA from blood samples. Methods: Dried, clotted and ethylene diamine tetra-acetic acid (EDTA) treated fresh and frozen blood samples were extracted using this method in which the quality and integrity of the extracted DNA were corroborated by agarose gel electrophoresis, PCR reaction and DNA digestion using restricted enzyme. The UV spectrophotometric and gel electrophoresis analysis resulted in high A260/A280 ratio (>1.8) with high intactness of DNA. Results: PCR and DNA digestion experiments indicated that the final solutions of extracted DNA contained no inhibitory substances, which confirms that the isolated DNA is of good quality. Conclusion: The high quality and quantity of current method, no enzymatic processing and accordingly its low cost, make it appropriate for DNA extraction not only from human but also from animal blood samples in any molecular biology labs.

Abstract: Background and Objectives: Antibiotic resistance is a major threat for human health that affects hospitalized patients worldwide; Hence, The World Health Organization (WHO) has chosen antibacterial resistance as its theme in 2011. Klebsiella pneumoniae is a gram-negative opportunistic pathogen and a common cause of nosocomial infections. These bacteria -especially in infants- are the cause of pneumonia, sepsis, meningitis, diarrhea and bacteremia. Increasing emergence of multidrug resistance (MDR) among Klebsiella pneumoniae nosocomial isolates has limited the appropriate therapeutic options for the treatment of infections caused by this pathogen. Beta-Lactamases are major defenses of gram-negative bacteria against antibiotics. Recently, the emergence of new β-lactamases such as NDM-1 (New Delhi metallo-β-lactamase-1), OXA-48 (Oxacillinase-48), OXA-181 (oxacillinase-181), KPC (Klebsiella pneumoniae carbapenemase), CTX-M-15 (Cefotaxime-M-15) confer resistance to the most antibiotics such as penicillins, carbapenems, cephalosporins, macrolides, aminoglycosides and sulfamethoxazole. Resistant genes are located on plasmids with different sizes and can be readily transferred between bacteria, from one human to another human, and even from one country to another. In 2011, it has been evaluated that the importance of some of these genes like NDM-1, KPCs is as AIDS, malaria and tuberculosis. These enzymes have emerged as an important threat for hospitalized patients. Some pathogens containing both KPC and NDM-1 may be mistakenly diagnosed as susceptible by conventional laboratory methods and hence they could have an important role in the emergence and spread of more resistant pathogens due to administration of ineffective drugs to patients. No vaccines have been found yet that prevent infections caused by carbapenemase-producing bacteria. Also, there is not enough information about frequency of these plasmid genes and their genetic profiles in Iran. Therefore, it is important to diagnose the Klebsiella pneumoniae strains producing resistant enzymes, especially NDM-1, for better treatment of patients and prevention of the spread of these genes to other bacteria via exact phenotypic and genotypic methods.

Abstract: In the area of Technical University in Ostrava were stabilized 35 points for testing of the accuracy of RTK measurement. All points of the testing base line were located by a new digital leveling instrument Leica DNA 03 with a precise leveling line. The position of all the points was determined by classical methods (polygonal traverse) as well. Each point was focused three times by the RTK method in relation to the same reference station. The point coordinates were located against the reference station, which was gradually placed in the attached points. The results of given point coordinates were compared mutually and with coordinates acquired by a classical method.

Abstract: The stream water quality of the Yalfan catchment of Iran has been studied intensively because of high organic pollutants loading to the Ekbatan Dam Lake. The influences of village`s wastewaters on the streamwater quality within the catchment were examined. The surface water has been contaminated with the faecal materials of man or animals. These pollutants could be contributed independently or in combination, to the very high levels in bacterial counts that were observed at this sampling site. All data include total and faecal coliforms counts, turbidity, pH, DO and COD at 11 different sites of the Yalfan River and demonstrate seasonal patterns for the period April 2003 to September 2004, which were divided on the dry seasons rainy seasons. The results indict that quality of the Yalfan River waters is generally better in the rainy seasons. But, the quantity of the wastes from human sources during the dry seasons is not very different to the rainy seasons. The total period analysis sheds no light on any significant trends in water quality over time within the year. The catchment situation`s resulting an important increasing of the COD, total coliforms and faecal coliforms at the end of Yalfan River direction that are in average 5, 10 and 13 times of upstream of the river, respectively. Conversely, dissolved oxygen level decreased along the river toward the end of direction. The averages of the total and faecal coliforms counts and so the COD throughout the sites were generally high of 1396 and 1185 MPN 100 mL-1 and 1209 mg L-1, respectively. This study generated some essential information of the Yalfan River pollutant sites that cause the microbiological contamination of the river as an important resource of Hamadan drinking water.
Obsessive-Compulsive Cognitions, Symptoms and Religiousness in an Iranian Population  [PDF]
Giti Shams, Irena Milosevic
International Journal of Clinical Medicine (IJCM) , 2013, DOI: 10.4236/ijcm.2013.411084

Individual differences in obsessive-compulsive (OC) behavior in various cultures appear to be associated with religiosity. The purpose of this study was to evaluate the role of religion in OC symptoms and cognitions in distinctly low and high religious groups from a normal community sample of 119 Iranian Muslims. Specifically, we compared the two groups on OC cognitions and symptoms, and we examined the correlations between the cognitive and symptom measures within each group. There was a trend for the high religious group to produce greater scores than those in the low religious group on the Obsessive Beliefs Questionnaire (OBQ) subscale of threat overestimation and responsibility. Furthermore, participants that were more religious achieved significantly higher scores on the Penn Inventory of Scrupulosity and on its Fear of God subscale. Although a number of significant correlations were observed between OBQ and Padua Inventory total and subscale scores, particularly in the low religious group, there was no conclusive relationship between religiosity and OC behavior and obsessional beliefs. Religion appears to be one more arena where OC symptoms expressed, rather than being a determinant of the disorder.
