Abstract: Introduction: Mission of Universities is to respond to the needs and expectations of its key stakeholders and specially their students. Quality promotion and continuous improvement of education and research processes in universities of medical sciences is important. Determining of student satisfaction level as the most important indicators to reach the desired quality should be considered. Thus this study with purpose of student satisfaction evaluation from education and research processes in Hamadan medical sciences faculties was performed.Material and Methods: This cross - sectional study was conducted in Hamadan University of Medical Sciences at 2011-2012. 385 students selected from all schools based on stratified method. To measure student satisfaction a researcher made questionnaire consisted of 71 questions related to various aspects of educational services (9 compasses) was used. Obtained data were analyzed using SPSS 16 software the chi-square test.Results: Most of the participants (72.2%) were in the age group 25 to 21 years. 50.3 percent of students were female. Most of students were at the undergraduate level (38.8%) and physician (32.9%). Level of satisfaction for all compasses was at moderate level. Based on statistic result only in internships and apprenticeships compasses satisfaction level showed a significant correlation with studying duration (P<0.05). Also in the teachers counseling, workshops and laboratory activity compasses the stratification level had a significance relation with degree (P<0.05).Conclusion: The results showed that the student’s satisfaction from educational processes is at moderate level. Satisfaction level based on degree of students is different, so managers and policy makers of educational system as well as teachers of various degrees can utilize the present study results to restructure of educational strategy in order to promotion the quality and the satisfaction level of educational services.

Journal of Research in Health Sciences , 2011,
Abstract: Background: Mental disorders have an important relationship with work conditions. Excessive workload, laborers needs and expectations ignorance, harmful physical agents, noise, poor lightning and bad work atmosphere result increasing stress and job dissatisfaction in workers. Methods: This descriptive-analytical survey implemented in order to investigate stress and job satisfaction rate of one of the Hamadan's factories laborers and its relationship with physical factors of work environment in 2001. Research population was the laborers of the old and new injection units (IS) of the factory. Data gathering tools were questioners, checklists and tools for measuring physical factors of work environment which all have been calibrated regarding to reliability and validity. Data analysis was performed using t- test, Chi-Square, and multiple regressions. Results: Findings showed that stress scores in both the old and new IS units were considerable. T-test showed a significant difference in the mean scores of stress (P < 0.05) and job satisfaction (P < 0.01) so that stress was higher in old IS unit and job satisfaction was higher in new IS unit. After measuring harmful physical factors in work environment it was revealed that Tergoison heat indicator (WBGT) in old IS unit was higher than new one (30.2 versus 24.7), adversely balanced sound pressure and light in new IS unit were higher than old one (96.27 to 94.74 and 57.2 to 37.62). Multiple regression analysis showed a significant relationship among stress components (pH physical condition) and job satisfaction. Conclusion: Findings of this survey showed that increasing of harmful physical factors in work environment leads increasing job stress and decreasing job satisfaction among laborers.

BioImpacts , 2011,
Abstract: Clinical applications of advanced nanomedicines such as PEGylated liposomal doxorubicin and paclitaxel-albumin bioconjugates have significantly improved the cancer treatment strategies. However, these pharmaceuticals lack early detection and single cell tracking capabilities. Thus, engineering of smart multifunctional theranostics appear to be our next stepfor simultaneous diagnosis and therapy of cancer. Clinical translation of multifunctional theranostics appears to be dependent upon specificity of cancer biomarkers, biocompatibility of components used for formulation, and advancement of bioconjugation techniques. While many cancer biomarker candidates often fail to be used for clinical diagnosis/therapy because of their nonspecific functional expression in normal tissues, biocompatibility of materials used for bioconjugationalso needs to be approved. All these issues need to be fully addressed prior to the translation of smart multifunctional cancer theranostics.
CNT Nanobombs for Specific Eradication of Cancer Cells: A New Concept in Cancer Theranosticss
Yadollah Omidi
BioImpacts , 2011,
Abstract: Whole extermination of cancerous cells/tissue seems no longer to be a dream. Exploiting advanced photoactive nanomaterials such as functionalized fullerenes and carbon nanotubes (CNTs) can act as CNT nanobombs (CNT-NBs) when exposed to the near infrared (NIR) radiation. PEGylated CNTs tagged with an antibody/aptamer can target cancer cells. Once attached to cancer cells, the NIR emission (700-1100 nm), in which body tissues are mostly transparent, can be applied to CNT-NBs which can absorb the light and get heated up. The resultant enhanced temperature can abolish the cancer. Once stealth CNT-NBs are tagged with imaging moieties, it would be a matter of computer gaming for physician who can inject it for real time visualization and destruction of cancer by activation of the NIR laser. While, many nanosystems (NSs) are still in waiting list for clinical translation, our dreams may come true by applying stealth CNT-NBs against cancer.

Mathematics , 2014,
Abstract: We consider four dimensional lie groups equipped with left invariant Lorentzian Einstein metrics, and determine the harmonicity properties of vector fields on these spaces. In some cases, all these vector fields are critical points for the energy functional restricted to vector ?fields. We also classify vector fields defining harmonic maps, and calculate explicitly the energy of these vector fields. Then we study the minimality of critical points for the energy functional.
