Abstract
Background: Continuous change in the complex health care environments is a major challenge for administrative managers. This study aimed to design a change model to facilitate change implementation in the Iranian hospitals. Methods: This is a descriptive and comparative study. The data were collected through library search and in-depth interview with 15 hospital managers. Nine well-established change theories developed by Lewin, Action Research, Kotter, Ackerman- Anderson and Anderson, Prosci , Kilman, Beer, Continuum, and Gelicher were compared. Common denominators of the theories were identified and tabulated. Experienced hospital managers’ suggestions about social factors were acquired. The initial model was designed and validated using the Delphi Technique. Results: The majority of the selected change models emphasize the significance of social factors in change implementation such as effective communication, organizational climate and culture, and leadership. The results from the interviews indicate that low readiness to change, lack of confidence (or trust) for change, and autocratic leadership style ,and poor communication could hinder the change process. Conclusion: Based on the model developed in the study, effective communication, readiness of employees, and a contingency leadership/management combined could lead to successful implementation of change in the hospital.

Abstract
Background: Life style changes have been considered in different ways in urban communities. Apartment housing, lack of physical activities, both parents being employed, entertainment devices relying on monitor display screens being within reach, leads our children to a sedentary life style. Obesity is just one of the side effects of this kind of living while children's confrontation with computer is decreasing to a lower age. There have been lots of surveys related to the duration of time spending on these entertainments with high school students but no research have been carried out on elementary school students in Iran. Methods: This cross-sectional study was carried on a sample of 450 male and female students attending the assessment center to register in the first grade in Karaj city. Results & conclusion: Therefore, in this survey, the average time new comers spent in front of a monitor screen was taken into account .The result showed that some part of child's daily activities was allocated to electronic devices having a monitor screen. Our findings showed that the allocated time for watching TV was 2.6 hours per day, for satellite programs: 0.49 hours per day, for Computer operating: 0.9 hours per day, Computer games: 0.38, and play station: 0.14hours per day and in total they used electronic devices 4.6 hour per day. Moreover, in this study, the BMI of each case has been calculated and the spread rate of weigh disorders was studied. About the weight disorders, we found that 15.8 % of students in this survey were low weight, 69.8 % were in normal ranges, 8.9 % were overweight and 5.4% were obese. In this survey, the relation between weight disorder and the rate of using electronic monitor screens was also studied. however, we couldn’t find any relevance between the two variables, probably the weight disorders must be affected by many other factors. We considered demographic variables as well as other variables which may affect weight disorder.

Abstract
Background: Cadmium chloride causes liver dysfunction. In the present study, the protective effects of hydroalcoholic extract of aerial parts of Alcea rosea against changes in biochemical factors and hepatic tissue induced by cadmium chloride in male Males were investigated.
Methods: In this experimental study, 56 adult male Wistar rats weighing approximately 200±10 g were divided into 6 groups of 9. The control group, The sham group 1 received 0.2 ml distilled water as solvent. The sham group 2 received 2 mg/ kg of cadmium chloride intraperitoneally for 21 days. Experimental groups 1, 2 and 3: 2 mg / kg cadmium chloride intraperitoneally for 21 days and then 450 and 300,150 mg / kg hydroalcoholic extracts of aerial parts of Alcea rosea received intraperitoneally for 30 days. At the end of the experiment, the body weight and liver weight of the animals were measured. Blood samples were taken to measure albumin, bilirubin and total protein levels. Liver tissue samples were studied pathologically after hematoxylin-eosin staining.
Results: The mean body weight in all experimental groups did not show significant changes compared to the sham group2. The mean liver weight in all experimental groups showed a significant increase compared to the sham group2. Mean serum bilirubin concentration in all experimental groups showed a significant decrease compared to the sham group2. The mean serum albumin concentration in the experimental group receiving 3 showed a significant increase compared to the sham group2. Mean serum albumin and total protein concentrations in the experimental group receiving 2 showed a significant increase compared to the sham group2 (P <0.05). In all experimental groups, the improvement of hepatic tissue changes induced by cadmium chloride was dose-dependent.
Conclusion: It is possible that the hydroalcoholic extract of the aerial parts of Alcea rosea improves the changes in biochemical factors and hepatic tissue induced by cadmium chloride in male rats.
