  Introduction: The success of hospitals in providing patient satisfaction depends on many factors. The role of employee's commitment to organizational behavior in patient’s satisfaction in hospitals is important. Methods: The present study is a methodological research in Tehran University of Medical Sciences, which aims to design a questionnaire for assessment of the employee's commitment to organizational behavior which was carried out in two phases. In the first phase we developed items pool based on a review of literature and expert’s views. In the second phase we evaluated content validity and face validity of items, and finally the reliability assessment of the instrument. Results: A questionnaire was developed based on a review of literature; an 80-items pool was formed. By interviewing experts, and omitting the overlap items, the number of items was reduced to 40 items. In the next stage, content validity, face validity and reliability of the items (α = 0.859) were proved, and the number of items were reduced to 17 items. Finally, we allocated 12 items (from 17 items) to be assessed by heads and colleagues. We also found that patients were able to evaluate the employee's commitment to organizational behavior through 5 items (from 17 items). Conclusion: An assessment tool contain 17 items was developed for assessment of the employee's commitment to organizational behavior, taking into account the views of service providers and patients.

  نصب ابزار دقیق و رفتارنگاری آنها در دوران ساخت و بهره‌برداری اولیه، کمک شایانی به ارزیابی پارامترهای پایداری   سد ها می کند. اهمیت ویژه ابزار دقیق در سدها به نقش آنها در کنترل پایداری کوتاه و دراز مدت سدها برمی گردد. بررسی رفتاری و نظارت های دراز مدت سدها، از اهمیت ویژه ای برخوردارند. به منظور رفتارنگاری سد بافت، نتایج اجرای مدل Plaxis در مراحل پایان ساخت و انتهای آبگیری برای مقادیر تنش و نشست مورد آنالیز و بررسی قرار گرفت. همچنین نتایج حاصله با نتایج مدل Geostudio و ابزار دقیق نصب شده در سد مقایسه گردید. که نتایج نشان میدهد،  بیشترین درصد خطا در محاسبه تنش قائم در نرم‌افزار Plaxis برابر با 3/25 و در نرم‌افزار Geostudio، 77/134 بوده و همچنین در محاسبه تنش‌ها در حالت کلی بیشترین درصد خطای نرم‌افزار plaxis بسیار کمتر از بیشترین درصد خطا در نرم‌افزار Geostudio بوده است و مقدار خطا در برآورد نشست در پایان ساخت سد با نرم‌افزار plaxis در مقایسه با نتایج ابزار دقیق، برابر با 78/1 درصد و بعد از آبگیری سد این مقدار برابر با 575/4 درصد بوده است. بنابراین تطابق نسبتا خوبی از مقایسه نتایج تنش‌های قائم بدست آمده با نتایج ابزار دقیق در پایان ساخت برقراراست. نتایج عددی نشست در نرم‌افزار Paxis نزدیک به ابزار دقیق بکار رفته در ساخت سد می‌باشد.     Manuscript profile

  Various types of numerical analyses such as the finite element method, the boundary element method and thedistinct element method, are used in rock mechanics and in engineering practices for designing rock structuressuch as tunnels, underground caverns, slopes, dam foundations and so on. In this paper, the results of backanalysis of Koohin tunnel which is located in the first section of Qazvin – Rasht railway have been presented.The main purpose of this paper is to perform the back analysis of the mentioned!tunnel with the use of numericalmodels. For modeling the tunnel, two different sections are analyzed with Flac 2-D software, which are 30+150and 30+900. To perform back analysis the suitable interval of geomechanical parameters according to the testswhich performed on the core drillings has been determined. With the use of Direct Method in back analysis, theerrors of models have been corrected in several steps and finally the geomechanical parameters of control in30+150 station (Elastic Modules = 0.3 GPa, Cohesion = 0.21 MPa & Internal Angle of Friction = 34°) and in30+900 station (Elastic Modules = 0.3 GPa, Cohesion = 0.21 MPa & Internal Angle of Friction = 35°) have beenachieved. The geomechanical parameters which achieved from back analysis are completely in the choseninterval and compliance with the results of tests which performed on core drillings. On this basis and accordingto the match of the geomechanical parameters which obtained from back analysis with the parameters whichused in designing of the tunnel, the tunnel design and the structure method were confirmed.

  The purpose of this study is to constract and standardize students critical thinking skills assessment questionaire. The methodological approach that is used in this research mixed method and according to the purpose of the subject, the type of exploratory research is a kind of tool development. This research is qualitative and quantitive quantization procedure. The combination data was quantitativey coupled to the data connection and weight was slightly higher than the stage. In the qualitative stage, for identifying the comonents of critical thinking and compiling tools from delphi technology and interviewing 6 experts. The small stage was a tool crated among 600, male and female student in kermanshah, who are studing at the fourth to sixth grade. To invistigat the factor structure of the questionare, we used r- software for exploratory factor analysis and lisrel 8.72 software is used for confirmatory factor analysis with random sample of 317people resulted in in seven factors that correlated with seven content factors and corrected 0/54 variance. The factor analysis the correlation between the factors, promax rotation was used. In the confirmatory factor analysis the exponetial estimation method was used with a population sample of of 283 people and a good fitness indexes were investigated. results of chi2 ratio on degree of freedom, RMSEA & SRMR accompanied with CFI & IFI point to good fit of model. In testing the psychometrics features, the amount of total chronbach alpha of 0.79 attained showing suitable validity. The test-retest cofficient of the questionare was 0/96 for 2 weeks, which shows the favorable reliability of questionnaire. Manuscript profile

  AbstractDespite all the advantages to human life, computer-mediated communication has provided a fertile ground for transgressive behaviors. Transgression is a behavior that goes beyond boundaries, conventions, laws, and accepted practices. The way societies confront transgressive behaviors, and the social control methods they employ to decrease these behaviors and reduce their mal-effects are of a high significance. Hence, the current research aimed at instrumentation for the measurement of the factors affecting social control of cybercultural transgressions. In the current research, six steps of instrumentation are presented as follows: 1) Identification and extraction of constructs from literature; 2) Validation of constructs and variables; 3) Validity assessment of item pool; 4) A priori reliability and 5) Post hoc reliability assessment; 6) Construct validity assessment; and also, the results of the instrument implementation including final model’s goodness-of-fit, and power analysis are presented. The results of instrumentation process showed an acceptable validity and reliability for the instrument. The steps outlined in the current research can lead to development of better instruments by researchers. Manuscript profile
