Background: patient satisfaction is known as his report of care quality and the interaction between the patient and health service providers and is an important criterion for assessing the quality of health cares. The aim of this research is to localize a self-administered questionnaire to assess the patients satisfaction hospitalized in a military hospital.Materials and Methods: This study is an action research. The research population includes the quality improvement unit experts, complaints handling unit, head nurses as well as the patients hospitalized in a military hospital in Tehran. Data were collected by semi-structured interviews and questionnaires as well as scientific texts. Stages of this study were as follows: 1. determination of the different dimensions of the questionnaire, 2. identifying questions related to each dimension, 3. modifying questions conceptually and contently, 4. confirming the face validity of the questionnaire, 5. confirmation of the reliability of questions using a pilot study and 6. Presentation of the final of questionnaire.Results: The self-administered questionnaire of inpatient satisfaction was localized in two sections, health and medical section with 21 questions and three dimensions of sanitation / hygiene, nurses and physicians and non-medical section with 27 questions and six dimensions of the reception, staff treatment, nutrition, the welfare and facilities, legal - faith issues and discharge. Cronbach's alpha coefficient in health and medical questionnaire and non-medical questionnaire was 0.975 and 0.936 respectively.Discussion and conclusion: In total, Alpha coefficient of the questionnaire indicates the high reliability and validity of the questionnaire and shows that this questionnaire can be used as a scientific instrument for self-administered assessment of hospitalized patient satisfaction. But it should be noted that to avoid bias, this method must accompanied with items such as measurement of patient satisfaction when leaving the hospital, concurrent use of other methods such as telephone surveys, periodic review and revision of the questionnaires and so on.

Ghrelin is a 28 amino acid peptide hormone that is expressed in the stomach and a range of peripheral tissues. Expression and functional role of ghrelin in the sex accessory glands of mammals have not been studied yet (except for human). This study was aimed to determine the immunohistochemical position of ghrelin in prostate, seminal vesicles and ampulla tissues of Holstein bulls. Anti-ghrelin mouse monoclonal antibody was used as primary antibody and donkey polyclonal antibody Anti-IgG Horseradish Peroxidase (HRP) was used as secondary antibody. Samples of sex accessory glands tissues were collected from five Holstein bulls aged two years old, and preserved in 10% buffered formalin for the immunohistochemical test. Then, paraffin blocks and tissue sections were prepared. The immunohistochemical results were positive for the secretory cells of prostate, seminal vesicles and ampulla. But the intensity of staining in the prostate glands was very weak than to the other glands. According to the results of this research, the expression of ghrelin in some accessory glands of the bull may display its possible role in fertility parameters of sperm and overall fertilization process.

Nowadays, it is a common idea to use decorative concrete panels as an alternative to natural stone. Graphic concrete is one of the different types of decorative concrete using the exposedaggregate method. Considering that there has been no research for graphic concrete production in Iran so far, the aim of this research is to localize and simplify the method for the first time. For this purpose, concrete samples with 435 kg/m3 and 500 kg /m3 Portland cement and water to cement ratio of 0. 40 and 0. 45 have been produced using natural sand as aggregate. Also, superplasticizer with dosage of 0. 35 % and air-entraining admixture with dosage of 0. 02% have been used. Concrete specimens were tested in terms of visual criteria, compressive strengths and water absorption in 28 days in accordance with the requirements of Iran National Standard 12038. The results showed that samples with the water to cement ratio of 0. 40, which were produced without using of superplasticizer and air-entraining admixture, due to low workability of the mixture, are not in good condition in terms of compressibility. Also low workability, in addition to disrupting the designs printed on the membrane, causes many holes on the concrete surface after leaving the mold, which is visually rejected. Despite the positive effects of air entraining admixture on workability, plastic viscosity and visual criteria, this type of admixture reduces the compressive strength by 30 to 35% and increases water absorption, which is not recommended. Finally, mixture design with 500 kg/m3 cement, water to cement ratios of 0. 40 and 0. 45, which were produced using superplasticizer with 28-day compressive strength of 54. 6 and 52. 5 MPa and water absorption of 3. 25% and 3. 50% while meeting all requirements are suitable for production of graphic concrete decorative panels.

Extended abstract:Introduction:The increasing population growth and tendency to live in the cities have led to maximum urban population for the first time throughout history. In fact, substantial rise in the population of the earth and overexploitation of environmental resources to meet economic needs have particularly influenced water resources. Iran is by no means an exception in this regard and increasing urbanism, particularly in metropolitans such as Tehran, has hindered the implementation of necessary policies to protect the environment generally and water resources specifically. At present, it is widely agreed that traditional approaches to water management in cities cannot be adequate for current and future sustainability. Thus, fundamental changes are required in technical and managerial structures of urban water systems. Some modern approaches should also be applied in sustainable planning for urban water. In this regard, a rather new concept in urban water management, namely "water-sensitive cities", has emerged since twenty years ago. This management which deals with offering ecological solutions to gain sustainability in urban development, calling for basic modifications in common methods in managerial, social and technical areas. The present study aims at localizing patterns of water-sensitive cities and determining Tehran's position compared with water-sensitive cities.

As a matter of fact, health monitoring of structures to ensure their safety and Integrity is very important. A factor that can endanger the safety and integrity is the process of occurrence of damage. Therefore, finding a way to identify damages is an essential issue. In this paper, damage LOCALIZATION of plate-like structures such as bridges and walls have been investigated. 9 virtual accelerometers have been placed in different locations of the structure to extract acceleration signals. Ultimately, two damage indices were introduced using continuous wavelet energy analysis. The most important advantage of the proposed method is that one can easily detect the approximate location of damage with a few number of accelerometers although there is no need to calculate mode shapes, obtain structural features of the structure and use expensive linear variable differential transformers (LVDTs).

Passive target LOCALIZATION has many applications in electronic warfare and passive defense. TDOA is the most accurate method in target LOCALIZATION. Following this method, one of the receivers is assigned as reference receiver and time difference of arrival between other receivers and reference receiver is measured. The target location is estimated by processing of these TDOA. The CTLS is one of TDOA based algorithm that has high accuracy and needs suitable initialization. In this paper, multi reference CTLS algorithm is proposed. CTLS algorithm accuracy was improved when multi reference receiver are considered instead of one reference receiver. Simulation results show that the proposed algorithm in different SNR, keep its improvement just with little increase of time processing and better performance compared to CTLS algorithm has been obtained.

In this paper, a higher order continuum model is presented based on the Cosserat continuum theory in 3D numerical simulation of shear band LOCALIZATION. As the classical continuum models suffer from the pathological mesh-dependence in strain softening models, the governing equations are regularized by adding the rotational degrees-of-freedom to conventional degrees-of-freedom. The fundamental relations in three-dimensional Cosserat continuum are presented and the internal length parameters are introduced in the elasto-plastic constitutive matrix to control the shear bandwidth. Finally, the efficiency of proposed model and computational algorithm is demonstrated by a 3D strip in tensile. A comparison is performed between the classical and Cosserat theories and the effect of internal length parameter is demonstrated. Clearly, a finite shear bandwidth is achieved and the load-displacement curves are uniformly converged upon different mesh sizes.

Free-form surfaces are usually described using the relationships of parametric surfaces such as Bezier, BSpline and NURBS. The computer-aided design systems use NURBS to describe complex (complicated) geometries. Free-form surfaces known as complex (complicated) surfaces are widely used in a variety of industries such as ship-building and molding, inspection of these surfaces is therefore of high importance (very important). Considering that measured free-form surfaces and design models are located in two different coordinate systems, finding the similarity of free-form surfaces and placing them in an identical coordinates system is necessary to compare these surfaces, this process is called LOCALIZATION. This paper introduces a feature and curvature based method for the automatic LOCALIZATION and comparison of free-form surfaces for inspection with coordinate measuring machine (CMM). This method localizes the measurement surface to the design model through two steps. The first step is general LOCALIZATION which is accomplished based on the relation and similarity between curvatures of free-form surfaces and zoning these surfaces to concave, convex and saddle areas. The second step is fine LOCALIZATION based on genetic algorithm which considers correspondence in the form of point to point. The simulation results show that the LOCALIZATION accuracy of the proposed method for the 50 × 50 mm aluminum workpiece of was about 0. 02 mm, which is 56 percent less than the value obtained from the iterative closest point method.
