The high prevalence of cardiovascular diseases among dental clients requires sufficient knowledge in this regard. For this purpose, we aimed to develop a valid and reliable questionnaire to assess the awareness of cardiovascular diseases among final year dental students.

After designing 38 questions, four areas were identified and to determine the validity, 7 specialists from the departments of Community Oral Health (2 people), Oral and Maxillofacial Diseases (2 people), Oral and Maxillofacial Surgery (2 people) and Cardiologist (n=1) evaluated the validity indicators and then to measure the reliability. The final form was distributed among 24 senior year dental students two weeks apart using the test-retest method and kappa statistics were calculated.

To determine the total validity of the instrument, the S-CVI value of the general agreement approach was 94.73% and in the mean approach was 87.84%. Also, the I-CVI values ​​of each question were above 0.70. Finally, out of the first 38 questions, 4 questions were removed due to lack of simplicity and the kappa coefficient of the remaining 34 questions, except for three questions, was obtained above 0.61, the middle of the total kappa coefficient was equal to 0.77.

With regard to desirable validity and reliability indices, it seems that this questionnaire is a useful tool to assess the awareness of dental students about cardiovascular diseases.

The root of the managers and teacher's behavior and activities is the ethical and moral values. Hence, considering professional ethics and its effects is among the most fundamental research topics in organizational areas. Accordingly, the present paper has attempted to investigate the role of professional ethics on social responsibility and individual accountability with considering the mediating role of serving culture. Research method of study is descriptive – correlation. The statistical population of this study included all male and female teachers (N=550) of Javanrood city in the educational year of 2013-2014. For data gathering in this study, a sample comprising 200 teachers in Javanrood city was selected by using stratified random sampling. The data were collected through standard questionnaires of professional ethics and social responsibility and a researcher made questionnaire of serving culture. To assess the relationships between Latent and measured variables in conceptual model, the Structural Equation model was utilized. Results indicate that professional ethics has a positive and significant relation with social responsibility, accountability, and serving culture. The results, also, show that the relationship between professional ethics and individual accountability is mediated by serving culture. But, the mediating role of serving culture in the relation of professional ethics and social responsibility was not confirmed. The results of this study hold out that professional ethics directly improves teacher's social responsibility and individual accountability. Individual accountability, also, strengthens teacher's serving culture. As a result of improved serving culture in an educational setting, we will have teacher's strong individual accountability.
