Abstract: Introduction: Cerebrovascular accidents are the third leading cause of mortality and the most important cause of morbidity in adults in the most of the world. Multiple factors such as Socioeconomic, lifestyle, environmental and genetic factors may be the cause of stroke risk differences in our community. This study was designed to evaluate the Stroke Risk Factor in persons above 55 years old without history of Stroke who referred to Health Centers in Hamadan on 2012.Material and Methods: In a Descriptive- Analytical study, 300 person above 55 years without history of stroke who referred to Health centers of Hamadan were selected (randomly),with regarded of inclusion and exclusion criteria and after explaining the research and its purposes, their permission was obtained. Their demographic data (such as age, gender), history of heart disease, hypertension and drug reception for it, diabetes, hyperlipidemia, smoking were filled in questionnaire. One EKG was performed (about the atrial fibrillation and signs of left ventricular hypertrophy).then data were analyzed and average tenth year stroke risk with use the Prof. Donald Smith software (stroke risk calculator) calculated.Results: The mean age, risk factors and systolic blood pressure in men and women were: 68.62±10006y, 2.16±1.33 and 129.05±18.71mmHg. History of diabetes mellitus, hyperlipidemia, smoking, hypertension(HTN), drug reception for HTN, drug reception in persons with history of HTN, SBP≥140mmHg, drug reception in persons with SBP≥140mmHg,Cardiovascular disease, atrial fibrillation(AF rhythm) and signs of left ventricular hypertrophy(LVH)in EKG have frequency: 19066%, 28%, 19%, 42023%, 34%, 29%, 59077%, 20033%, 3033%, 8033% respectively. The mean calculated stroke risk was for tenth year 10071%.This risk was 11074% in men and 9052% in women population.Conclusion: It’s can be concluded that with regard to transition of socioeconomic and community especially aging and international experience of epidemiologic transition, stroke risk factors and consecutive stroke risk in Hamadan as a small sample of a developing country are rapidly increasing .

Abstract: Recent advances in the study of affective-cognitive regulation of aggressive behavior suggest positive correlations between poor executive capacities (ECF) and negative reactivity. If the global assumption is correct what are the likely implications of predicted relation? The central issue in present research is to verify this assumption and examine how situational characteristics can alter executive performance in adults experiencing Civil War (Syrians students living in their country or in a host country) and adults experiencing peaceful life (French students) to explore some of the consequences of those modifications for aggressive and anxious tendencies. Precisely, we expect the positive correlations between poor executive performances and high dispositional as well situational aggressive and anxious tendencies, specifically for adults exposed to warfare. In order to assess executive capacities and dispositional as well as situational aggressive and anxious tendencies, during one pilot and two comparative studies [pilot study: N = 60 female French students; first comparative study: N = 60 French and N = 60 Syrian students of both sexes (50%); second comparative study: N = 60 Syrian students of both sexes (50%) living in France] right-handed French/Arabic-speakers participants complete twice, before and after completion executive tasks (standard neuropsychological tests) under different experimental conditions (Aversive/Neutral condition), a series of aggression and anxiety questionnaires. The results provide evidence of a dispositional relationship between poor executive functioning and negative reactivity, and extend it to situational level. For all participants, it shows that increases in impulsiveness (negative emotionality and aggressive choices) due to an aversive noise (80 db) are concomitant with an inability to focus individuals’ attention on ongoing tasks, specifically in those living directly or indirectly stressful life-event.

Computer Science , 2014,
Abstract: To cover a set of targets with known locations within an area with limited or prohibited ground access using a wireless sensor network, one approach is to deploy the sensors remotely, from an aircraft. In this approach, the lack of precise sensor placement is compensated by redundant de-ployment of sensor nodes. This redundancy can also be used for extending the lifetime of the network, if a proper scheduling mechanism is available for scheduling the active and sleep times of sensor nodes in such a way that each node is in active mode only if it is required to. In this pa-per, we propose an efficient scheduling method based on learning automata and we called it LAML, in which each node is equipped with a learning automaton, which helps the node to select its proper state (active or sleep), at any given time. To study the performance of the proposed method, computer simulations are conducted. Results of these simulations show that the pro-posed scheduling method can better prolong the lifetime of the network in comparison to similar existing method.

International Journal of Hospital Research , 2012,
Abstract: Background and Objectives: Balanced Scorecard is an increasingly popular tool for performance evaluation. Health-care organizations have broadly adopted this method for implementing their strategic plans. There is, however, increas-ing concerns on barriers to balanced scorecard implementation. Built on the fundamental impacts of organizational culture on hospital performance, this study explored the relationship between balanced scorecard effectiveness and organizational culture.Methods: A descriptive analytical study of cross-sectional design was conducted within the period of August 2009 to June 2010. One hundred and fifty employees of Hasheminejad Kidney Center were enrolled. The questionnaire com-prised two items addressing balanced scorecard effectiveness and 60 items related to four dimensions of organizational culture, including Involvement, Consistency, Adaptability, and Mission. Validity of the questionnaire was examined by seeking expert opinion. A high reliability of the questionnaire was ensured by obtaining a Cronbach’s alpha of 0.94. Sur-vey results were summarized using descriptive statistics. The relationship between organizational culture and balanced scorecard effectiveness was measured using Pearson’s correlation coefficient, and modeled via regression analysis.Findings: Balanced scorecard effectiveness showed significant correlations with Involvement (r = 0.44, P < 0.01), Consistency (r = 0.27, P < 0.01), Adaptability (r = 0.28, P < 0.01), and Mission (r = 0.35, P < 0.01). Multiple regression analysis identified Involvement as the only predictor of BSC effectiveness (β = 0.431, P < 0.01).Conclusions: While all factors of organizational culture can influence balanced scorecard effectiveness, employee involvement holds prime importance. Hence, hospital leadership needs to strongly encourage employee involvement in organizational processes, in order to achieve high effectiveness of balanced scorecard.

Abstract: BACKGROUND: One of the frequently used measures of research performance of a country or a university is counting the related scientific production. In the present study the number of scientific production including research projects, books, journal articles and conference proceedings published under the name of Isfahan University of Medical Sciences were identified and then compared with those reported by Iranian Ministry of Health and Medical Education for the year 1384. The purpose of this study was to identify one-year research performance of Isfahan University of Medical Sciences and to show the growth rate of scientific production of this university from 1384 to 1385. METHODS: The present cross-sectional study was carried out by reviewing related official documents and running advanced searches in some of the most important databases. The time limitation was set on 1385 hijri shamsi, which is equal to the beginning of April 2006 till the end of March 2007. RESULTS: During the period of the study, Isfahan University of Medical Sciences published 56 books. The total number of approved research projects was 1080, most of which (61.67%) were descriptive studies. A total of 721 journal articles published by the university researchers of which 146 papers were indexed by ISI, 26 papers were indexed by MEDLINE, 194 papers were indexed by EMBASE, Scopus, Biological Abstracts, Chemical Abstracts and CINAHL, 318 articles were indexed by other databases. Only 37 articles published via non-indexed journals. 74.2% of the articles appeared in domestic journals while only 25.8% published in foreign journals. The total number of national and international conference proceedings was 726. The findings showed a significant increase (nearly 100%) in all kinds of scientific productions compared to those published in 1384 except the published books. CONCLUTIONS: The present study indicates that despite suffering from limitations in annual research budgets and facilities, research performance of Isfahan University of Medical Sciences has increased appreciably during the last year.

Abstract: Fear is an undesirable feeling which most of the time results in physiological changes and can affect on the cardiovascular function of the patient. This research is a cross-sectional descriptive study that describes the congruency opinions between 91 patients /nurses about the reasons for patients’ fear related to coronary angiography in two affiliated hospitals of Tehran University of Medical Sciences. The tools which were used included: questionnaire for study and recognition of patient and nurses demographic characteristics, a check list containing thirty probable reasons for patients’ fear which were filled out by patients and nurses, and a scale for analysis of the reasons for fear which were filled out by patients, descriptive statistics indicators, sign test, and t-test were applied in order to analyze the data, by SPSS software. The results showed that patients’ and nurses’ ideas about the reasons for fear before angiography are similar in two cases and only in one case after the operation. Among the thirty probable reasons which were mentioned for patients’ fear, seventeen cases caused less fear after angiography and two cases caused more fear after that. In the comparison between the intensity of fear caused by other reasons no insignificant result was observed. The comparison of intensity of fear showed that the intensity of patients’ fear after angiography is less than before (p= 0.005). According to these cases it may be concluded that because of the different reasons for patients’ fear concerning angiography, nurses need to pay more attention to patients’ fear. It is also suggested that an assessment tool be used in order to assess issues relating to patients, level of care and training related to coronary angiography.

Abstract: Introduction: Shape and size of upper anterior teeth are important in dental and facial beauty. The aim of this study was to determine the correlation between dental and facial indexes and to evaluate whether there is a golden ratio and its relationship with the proportions measured.Materials and Methods: In this cross-sectional study, digital images of 34 female and 30 male dental students were taken at maximum smile in a similar manner. Then the images were assessed with Photoshop CS5 and ACDSee computer programs and measurements were made with AutoCAD 2011 software. Data was analyzed with independent t-test and means were compared with a constant.Results: The entire variable means did not demonstrate any significant differences between males and females (p value > 0.05). The inter-pupillary to inter-canine distance ratio did not reveal any significant differences with the golden proportion of 1.618 between males and females (p value > 0.05). Only the ratios of inter-pupillary, inter-canthus and inter-zygomatic distances to maxillary central widths in females, and the ratios of inter-zygomatic and inter-alar distances to maxillary central widths in males were not significant.Conclusion: Under the limitations of the present study, it was concluded that dento-facial proportions are not significantly different between males and females and the golden ratio applies in the inter-pupillary to apparent width of anterior maxillary teeth proportion. Facial indices are appropriate measures to measure the apparent width of anterior maxillary teeth and can be used as a standard for Iranian dentists and surgeons. Key words: Anterior teeth, Dental position, Diastema, Proportion.

Abstract: This paper describes a dispersive liquid–liquid microextraction (DLLME) procedure using room temperature ionic liquids (RTILs) coupled with flame atomic absorption spectrometry detection with microsample intro-duction system capable of quantifying trace amounts of lead. In the proposed approach, ammonium pyr-rolidine dithiocarbamate (APDC) was used as a chelating agent and 1-hexyl-3-methylimmidazolium bis (trifluormethylsulfonyl)imid as an extraction solvent was dissolved in acetone as the disperser solvent. The binary solution was then rapidly injected by a syringe into the water sample containing Pb2+ complex. Some factors influencing the extraction efficiency of Pb2+ and its subsequent determination, including extraction and dispersive solvent type, pH of sample solution, concentration of the chelating agent and salt effect were inspected by a full factorial design to identify important parameters and their interactions. Next, a central composite design was applied to obtain the optimum points of the important parameters. Under the optimum conditions, the limit of detection (LOD) was 0.2 µg/L. The relative standard deviation (R.S.D) was 1.4% for 5 µg/L of Pb2+ (n = 7). The relative recovery of lead in seawater, blood, tomato and black tea samples was measured.
