    Background and
    Purpose
    The main objectives of this research were to evaluating the application of electrocoagulation process for 198 dye from the aqueous phase and determining the optimum operating conditions to the dye removal using aluminum and iron electrodes.
    Materials And Methods
    The present study was conducted in bench-scale. The spectrophotometer DR 5000 was used to determine the dye concentration. The effects of pH, retention time, voltage, dye concentration on the efficiency of electrocoagulation process were investigated. Data were analyzed in SPSS for Windows 16.0 using Pearson’scorrelation coefficient to analyze the relationship between these parameters.
    Results
    The results showed that the optimal conditions for reactive red 198 (RR-198) dye removal from the aqueous solution are pH of 11, the voltage of 32 V, the initial dye concentration of 10 ppm, and the reaction time of 40 min. Pearson correlation analysis showed that there is a significant relationship between voltage and the reaction time with the removal efficiencies (P< 0.01).
    Conclusion
    It was revealed that the removal efficiency of dye was directly proportional to the voltage and reaction time, but inversely proportional to the initial dye concentration. In conclusion, electrocoagulation process using two-fold iron and aluminum electrodes is an appropriate method for reducing the RR-198 dye in the aqueous phase.

    Background and
    Purpose
    Now-a-days, patient satisfaction is increasingly receiving the attention of health-service providers, which is a necessary step to enhance the quality of health services. The present study aimed at exploring patient-physician communicative patterns, physicians’ job satisfaction, and patients’ satisfaction at Isfahan, Iran.
    Materials And Methods
    This study was a descriptive analytical and cross-sectional survey in the summer of 2010. Simple random sampling was used to select participants. Data were collected through using three self-designed questionnaires on physicians’ job satisfaction, patient-physician relationship patterns (based on Hollander and Szase’ ideas), and patients’ satisfaction. Validity of the questionnaire was checked by a panel of experts. Furthermore, internal consistency reliability of the questionnaires was confirmed by Cronbach’s alpha (α = 0.80). Different dimensions of the job satisfaction questionnaire were salary, supervision, setting, promotion, fringe benefits, and working conditions. Data were analyzed by using SPSS for Windows 13.0 software.
    Results
    The mean score of patient-physician relationship was 63. Therefore, the most frequent patient-physician communication pattern was guidance-cooperation. The mean score of physician’ job satisfaction was 50.2. The mean score of patients’ satisfaction was 86.5. Physicians’ job satisfaction was found to be related to patient-physician communication pattern (P < 0.05).
    Conclusion
    Although patient-physician communication patterns are important, different variable such as patients’ and physicians’ satisfaction influence the patterns. Furthermore, improvement communication process between health care providers can be useful in the increasing patient satisfaction and patient quality of care.
