M Alimohammadi Ardakani,SH Mirghafoori,SH Mirfakhradini,A Damaki
Journal of Shahid Sadoughi University of Medical Sciences , 2009,
Abstract: Introduction: Performance measurement, programming and goal setting for performance improvement are needed for organizations to improve their performance. Despite advancement in performance measurement systems, many organizations still emphasize on old models. Methods: This paper analyzes the efficiency of Yazd governmental hospitals by using DEA model from 2004 to 2006. The inputs in DEA model are 3 variables including number of physician, number of health personnel and number of beds. The outputs in DEA model are also 3 variables; number of in-patients, number of out-patients and number of bed days. Results: This paper results suggest that hospitals in Ardakan, Maybod, Khatam and Tabas Counties and only Afshar hospital in Yazd city are efficient. Inefficient hospitals include Savaneh Sookhtegi hospital of Yazd city and the hospital in Abarkooh County. Also, this paper determined the input and output targets of efficient and inefficient hospitals. For example, hospital in Taft County is efficient when number of inpatient increases to 54494, number of outpatients increases to 5225 and number of bed days increases to 21009 by output orientation model. Conclusion: Manager of hospitals can measure efficiency of hospital sections by using DEA models and plan for efficiency improvement, respectively.

H Mirghafoori,H Zare Ahmadabadi
Journal of Shahid Sadoughi University of Medical Sciences , 2007,
Abstract: Introduction: Many organizations, especially service oriented ones, relative to their goals and mission, have a special view towards quality phenomena and its management. Methods: This paper analyzes medical service quality in one case; The internal section of Shaheed Rahnemoon Hospital Based on the basis of gap analysis model and Servqual technique. A questionnaire was designed and applied to measure expectations and perceptions of patients and personnel of the hospital. Results: On application of non-parametric statistical tests, we propose certain recommendations. These tests drive on five conceptual dimensions of service quality including intangibility, responsiveness, reliability, assurance and empathy. Results show that patients in this section were satisfied from the service provider’s responsiveness, but there are significant differences between expectations and perceptions in other dimensions. Conclusion: The service quality analysis models are useful for managers of medical centers to distinguish gaps between the two sides of service representation; patients and medical centers personnel. Ultimately, they can reinforce strengths and control weaknesses.

M Asadi,H Mirghafoori,Z Sadeqhi Arani,H Khosravanian
Journal of Shahid Sadoughi University of Medical Sciences , 2011,
Abstract: Introduction: Evaluation is an important factor in productivity context, and acts as a control system for other areas of productivity. Hospitals are large organizations incurring heavy expenses in every country. The level of efficiency in a hospital is a good criterion to understand how hospitals consume their resources. The goal of this research was to determine relative efficiency of 13 public hospitals in Yazd province by using integrated DEA, BSC and SERVQUAL model. Methods: In this study, relative efficiency of 13 public hospitals of Yazd province was calculated using data envelopment analysis technique(DEA) and balanced score card and servqual. BSC was used as a tool for designing of performance evaluation indexes, while DEA was used as a tool of evaluating performance and ranking. Results: The mean relative efficiency of hospitals under study was about 0.945 in the Persian calendar year 2008-9. The efficiency levels of nine hospitals were borderline and the efficiency of four hospitals was less than 1. Hospital no.3 had the highest efficiency levels and hospital no.10 had the lowest efficiency level. Conclusion: In this stage, on the basis of references presented by the DEA model, solutions for increasing the quality performance levels of inefficient hospitals in fourth dimensions were determined and some suggestions were proposed. Although all performance indices of the inefficient hospitals need to be addressed, priorities have to be determined by the respective managers.
Phenomenological and Semi-microscopic Analysis for the Elastic Scattering of Protons from 12C Nuclei at Different Energies  [PDF]
Sh. Hamada, N. Amangeldi
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.45B013

Analysis of the elastic scattering of protons from 12C nuclei had been performed within the framework of both the optical model and single folding model at different proton energies; 17, 30.3, 40, 49.48 and 61.4 MeV. We have obtained the global potential parameters which could fairly reproduce the experimental data for p+12C elastic scattering at the aforementioned energies. The radial and energy dependence of the real and imaginary parts of the potential were calculated. Good agreement between experimental data and theoretical predictions in the whole angular range was obtained using both phenomenological approach (Optical Model), and semi-microscopic approach (Single Folding). In single folding calculations, the real part of the potential was calculated from a more fundamental basis by the folding method in which the NN interaction VNN(r), is folded into the density of the target nuclei and supplemented with a phenomenological imaginary potential. The obtained normalization factor Nr is in the range of 0.75 - 0.9.

Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.46114

We have measured the angular distributions for 12C ion beam elastically scattered from 12C target of thickness 17.4 μg/cm2 at energies 15, 18 and 21 MeV which is close to the Coulomb barrier energy for 12C + 12C nuclear system. The elastic scattering of 12C beam on 12C was analysed also at different energies (139.5, 158.8, 180, 240, 288.6, 300, 360 and 420 MeV) from literature in order to obtain the global optical potential parameters, which could fairly reproduce the experimental data. The experimental results were analysed within the framework of both the optical model and the double folding potential obtained with different density-dependent NN interactions which give the corresponding values of the nuclear incompressibility K in the Hartree-Fock calculation of nuclear matter. The agreement between the experimental results and the theoretical predictions in the whole angular range is fairly good.

Ergodicity and Invariance of Flows in Queuing Systems  [PDF]
G. Sh. Tsitsiashvili
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.67122
Abstract: In this paper, we investigate the flow of customers through queuing systems with randomly varying intensities. The analysis of the Kolmogorov-Chapman system of stationary equations for this model showed that it is not possible to construct a convenient symbolic solution. In this paper an attempt is made to circumvent this requirement by referring to the ergodicity theorems, which gives the conditions for the existence of the limit distribution in the service processes, but do not require knowledge of them.

Journal of Dental Medicine , 2004,
Abstract: Statement of Problem: Ceramics and resins belong to the earliest tooth restorative materials. Nowadays new generations of these materials have provided a revolution in cosmetic dentistry. Ceramic Optimized polymer (Ceromer) is a newly made product that the bond between this material and base metal alloys, which are used widely today, is paid too much attention. Purpose: The aim of this study was to evaluate the bond strength of targis (Ceromer) to three types of base metal alloys through three different surface treatment methods. Materials and Methods: In this experimental study, ninety plates of Rexillium III, Silver cast and super cast alloys (30 5 0.4) were prepared and surface treated through three different methods (air oxidation, vaccum oxidation and sandblast). All samples were then veneered with 1.mm thickness of Targis. After thermocycling, three-point bending test was performed by universal testing machine (Instron) to evaluate the amount of forces at crack or fracture times in Targis. The type of failure (cohesive or adhesive) was also evaluated microscopically. Statistical analyses were made using 2-factor ANOVA and Duncan tests. Results: The type of surface treatment method caused a statistically significant difference in force rate required for crack and fracture in Targis. Sandblasting was found as the best method. The type of alloys, in all three methods, had a significant effect just on crack creation attributing the largest amount of force to Rexillium III. Adhesive type of failure occurred mostly in super-cast alloys through air-oxidation method, and cohesive type was more among silver cast alloys and sandblast method. Conclusion: According to the results of this study, bond strength between Ceromer materials and base metal alloys is significantly great and Rexillium III alloy associated with sandblast technique the best combination.
