Today, information technology has had many benefits in accelerating and facilitating maintenance activities, creating a branch called E-maintenance. Implementation of a E-maintenance system for defense organizations that have problems with the military equipment maintenance, has a major impact on their success or failure on missions and can facilitate and improve the effectiveness of the maintenance. To go beyond traditional maintenance approaches, and to create an e-maintenane framework, one needs to evaluate the state of e-maintenane maturity, to identify its current position in e-maintenance maturity, and to plan for the full maturity of electronic net. Due to the lack of a maturity evaluation model for the e-maintenane system, the aim in this research is to present a maturity evaluation model of the e-maintenance system for defense organizations. By examining the literature of the subject, and related maturity models, and preparing a questionnaire for people's opinions, expert in the field of maintenane, the maturity model was presented in 6 dimensions and 67 indices, and maturity levels were based on CMMI. Finally, on the basis of a checklist extracted from the defined maturity indices and levels, the maturity of a defense organization's e-maintenance system was evaluated.

Sustainable and high economic growth has always been one of the most important development indicators of countries and its achievement is considered to be the most important economic goal of the states. As a result, identifying the factors influencing economic growth and using these factors as a means to achieve high growth rate, is so interesting for researchers and its results are important for policy makers. On the other hand, security and defensive power are also important indicators of welfare in different of economic, social and cultural aspects of life. This study aims to achieve a balance between these two goals and examine their relationship. The main questions of this study are the relationship between economic growth and security and defensive power. Is this relationship different among different countries? In this regard, after examining the indicators, military expenditures to GDP ratio is used as a proxy for security and defensive power. This research divides countries into two groups of major exporter and importer of military equipment and uses panel data regression analysis to estimate the model using Eviews software. The research has used data of 28 countries during 2005 and 2015. Results show that the increased military spending will lead to an increase in economic growth in exporting countries of military equipment, although leading to a decline in economic growth in the importing countries of military equipment

In this paper, design, simulation and fabrication of compact quad-band bandpass filters (BPF) using Split Ring Resonators (SRR) are presented. These types of filters are inherently narrow bandwidth. The bandwidths of the passbands of the filter are increased using an interdigital capacitor between two adjacent cells of the filter, and by increasing the substrate thickness. A quad-band BPF with center frequencies of 1. 5, 2. 24, 3. 07 and 4. 43 GHz was designed and simulation results show the bandwidths of these bands are 120, 219, 492 and 280 MHz respectively. In order to adjusting the center frequencies and their bandwidths for practical applications, parametric study and required simulations are presented. The proposed structure has sharp passband selectivity, acceptable insertion loss and return loss in each band, and controllable distance between the bands. Final filters (two structures) are implemented on Rogers 5870 substrate, and simulation and measured results are compared. Second fabricated filter has a compact size of that shows 18%, 69% and 43% size compacting in compare with three samples of quad-band filters of other references.

Knowledge is a valuable and strategic resource and is also the most important variable for the growth of all-around health-oriented organizations and enterprises. Today, organizations are not limited to capital and human resources. As a result, organizations have stepped up knowledge management to improve and maintain their competitive power. This competition is also based on health-oriented organizations and related to community health systems. In organizations and health systems, there is a gap between knowledge management and their performance, which should be removed by a model of that distance. The aim of this study was to design a model that can determine the levels of knowledge management in the communication system, and the role and interactive functions of these layers in achieving the organization's goals, including sharing and applying knowledge.
This is an applied research, but the research method is descriptive / survey type and, the method of data collection is quantitative type that a group sampling method was used for collecting data. The sample size of the target population was estimated to be 70 person. In this research, with the extensive review of theoretical foundations, the primary factors influencing the model were set and after the initial questionnaire of the research and obtaining opinions of the experts and modifying the factors of the conceptual model of the research were designed, in which two factors and several components were identified and explained. After clarifying the factors, components and indicators of the knowledge management system in large organizations, using the coefficient of significance and load factors using Smart PLS software, confirmed the research hypotheses, and then the final model of knowledge management system was designed.
The first part included a review of the meaningful coefficients Z (values of t-values) for each of the hypotheses. The output of the model showed that the 14 coefficients of the paths between the components determined in the conceptual model of the research were significant. The output of the standardized coefficient of the path between the components and factors showed that the policy component determined 92% of the changes in the level of organizational factors directly.
The proposed model in the knowledge management system of large organizations, such as health-based organizations, is a simple yet feasible model that has been used as a bridge in knowledge management and organizational factors.

Anaphylaxis is a potential life threatening condition which may control by proper diagnosis and efficacious management. The aim of this study was to determine the level of knowledge of anaphylaxis diagnosis and management in pediatric residents.
Subjects & This study was conducted in teaching hospitals of Tehran University of Medical Sciences. A total of 192 pediatrician and general and subspecialty pediatric residents during Sep. 2013 to Feb 2014 were included. They were asked to complete a 19 item questionnaire. Collected data analyzed using SPSS (version19) software. p Almost all respondents knew anaphylaxis as a life threathening event, however 23.4% didn’t answer correctly to the questions about signs and symptoms of anaphylaxis. None could determine therapeutic steps of anaphylaxis correctly, however, 94.7% agreed to administer epinephrine as the drug of choice for treatment (P=0.014). Only 78.1% correctly identified intramuscular route of epinephrine administration as the route of choice (0.000) and 71.4% used the proper dose. About half of participants knew about in-hospital observation time.
the present study indicated that, pediatricians and pediatric residentsoften are not very familiarwith the proper dosage of epinephrine, administration route and the optimaltime for hospitaldischarge in anaphylaxis. herefore, it seems that theoretical education about anaphylaxis is not sufficient to provide pediatric residents for clinical practice.

ECRHS questionnaire used for the survey of respiratory symptoms and asthma. In this study the prevalence and associated respiratory symptoms and spirometric indices in Tehran University students were assessed using a questionnaire ECRHS during 2013-2014.
In this cross-sectional study, 1729 students from all faculties of Tehran University of Medical Sciences were evaluated at ages 20 to 44 years. The first step for screening respiratory symptoms questionnaire was completed by volunteers ECRHS I that 671 people were excluded because test is negative, and 997 patients because of the reluctance to enter the second phase of the study did not ECRHS II, and 61 patients were entered into the second phase ECRHS questions at this stage was completed by a doctor.
The mean age of participants with respiratory symptoms was 23.2±3.7 (20-44), that 508 (48%) men and 550 (52%) were female. Prevalence of respiratory symptoms according ECRHS I for all the symptoms 61.2%, respectively, the most frequent wheezing (33%), and the symptoms of allergic rhinitis (73.4%), the prevalence of diagnosed asthma was 9.3%.
Significant direct correlations were found between MEF 25-75 ∆ and With waking with a feeling of heaviness on chest , with Difficulty breathing , between FVCex ∆ and Attack of shortness of breath at rest, between FVCex with Respiratory symptoms during certain times of the menstrual cycle , between FEV1 with Respiratory symptoms during certain times of the menstrual cycle. Also, between allergic rhinitis with FEV1 , between MEF 25-75 with allergic rhinitis, and FEV1/FVC ∆ with allergic rhinitis were found Significa nt direct correlations. But, no significant direct correlations were found between allergic rhinitis with FEV1/FVC, between allergic rhinitis with FVCex ∆.
Asthma seems to be a pattern of high prevalence of risk factors including Environmental, labor, industrial pollution, housing, behavior issues, misconceptions of the disease, lack of education to patients by clinicians. It seems that for improve asthma control, ECRHS questionnaire and spirometry test may be used as a complementary tool in clinical practice to detect adults with asthma and respiratory symptomes.
