Physiologic Effects of Intra-nasal Sedation with Midazolam and Ketamine in 3-6 Years old Uncooperative Children

Objective: Several medications have been used for sedation in children in dentistry and intra-nasal route has been reported to be an efficient way regarding patient cooperation. The aim of the present study was to compare the changes in physiologic parameters following intra-nasal midazolam and ketamine administration.Methods: In this randomized cross-over double-blind trial, 17 uncooperative 3-6 years old children requiring at least two dental treatments were selected randomly and received intra-nasal ketamine (0.5 mg/kg) and midazolam (0.2 mg/kg) prior to the treatment using the other drug in the next visit. Physiologic parameters including blood pressure, heart rate, respiratory rate and O2 saturation were measured and compared during the different time intervals using two way repeated measure ANOVA.Results: The patients showed higher blood pressure and heart rate following ketamine administration compared to midazolam (p<0.001). No significant difference was found between the drugs at different time intervals regarding respiratory rate and O2 saturation. (p>0.05)Conclusion: In spite of significant differences between midazolam and ketamine regarding heart rateand blood pressure, both drugs can b e used as effective sedative medications without treatment interruption in children

Environmental Knowledge of and Training Methods for Physicians and Nurses of Pars-e-Jonoubi Company, Iran

Background & Objective: Having employees with appropriate environmental behaviors and paying attention to their environmental knowledge and training is an important issue especially for industrial companies. However, the lack of prioritization of this important issue is one of the effective factors in the declining trend of environmental performance improvement of industrial companies. Therefore, the main purpose of the present study was to evaluate the environmental knowledge of physicians and nurses working at Pars-e-Jonoubi Company, Iran, and propose appropriate methods for their environmental training. Methods: This research was a descriptive survey. The statistical population included all physicians and nurses working at Pars-e-Jonoubi Company, from among which 135 individuals were selected through random stratified sampling method and based on the Morgan Table. The data collection tool was a researcher-made environmental knowledge questionnaire based on the view of Frick et al. Data was analyzed using descriptive statistics, t, independent t, Friedman, and chi-square tests. Results: The knowledge of physicians and nurses, in their own view, regarding environmental systems was near average (3.1 and 3.3, respectively). Physicians’ and nurses’ knowledge on environmental action was near average (3.2), and below average (2.6), respectively. Their knowledge of effectiveness was higher than average (physicians: 3.8, nurses: 4.3). Generally, physicians estimated their environmental knowledge as slightly higher than average (3.6) and nurses as nearly average (3.2). Moreover, there was a significant difference between the average of the three aforementioned dimensions of their environmental knowledge and the criterion average. In addition, there was a significant difference between the average of the three dimensions of environmental knowledge of physicians and nurses. They also ranked environmental training methods differently. Descriptive statistics and chi-squared test showed that 76 subjects (61%) preferred the compulsive environmental training method and 48 subjects (39%) preferred the optional method. Conclusion: The results of this research indicated that physicians and nurses working at Pars-e-Jonoubi Company felt the need for obtaining, generally, more environmental knowledge, and specifically, more action-related knowledge. Thus, it is suggested that the necessary requirements be provided for the environmental training of physicians and nurses working at this company according to each group’s preferred training method.

Job satisfaction and organizational commitment as antecedents of Organizational Citizenship Behavior (OCB) of teachers

AbstractLittle empirical research has looked at casual relationships between job satisfaction, organizational commitment and OCBs of teachers. Also there is minimal attention to the impact of specific facet of job satisfaction and organizational commitment on OCB of teachers. The purpose of this study was to investigate casual relationships through testing 36 structural models. The sample was 652 teachers and 131 principals. Data were collected through 3 questionnaires. Results showed that just 1 model has the best fit indexes. In this model, intrinsic job satisfaction is a dominant variable which influence OCB directly and indirectly through partial mediating role of value commitment

The role of organizational virtuousness in organizational citizenship behavior of teachers: The test of direct and indirect effect through job satisfaction mediating

The aim of this study was to test the direct and indirect effect of organizational virtuousness in organizational citizenship behaviors of teachers and propose a model with a causal connection. The population consisted of all secondary school teachers of Karaj metropolitan areas where by cluster method sampling and Morgan table 403 people selected.

To analyze the data confirmatory factor analysis and structural equation modeling techniques used. The results showed that schools organizational virtuousness directly affect Less and non-significant on organizational citizenship behavior of teachers. The assumed test pattern suggests that organizational virtuousness with the mediation of job satisfaction can affect the behavior of teachers' organizational citizenship behavior. The findings of this study emphasis the importance of reinforcement of schools as well as teachers' job satisfaction and organizational virtuousness

Policies, Patterns and Principles of Successful School Management (Review of Findings International ISSPP Project)

High drop-out rates, low test scores, and rising social disruptions in schools are prominent indicators that education should change based on that, and management should be considered as a solution to problems. This article reviews the successful school management literature. In fact, the main focus is on the international literature of successful schools, especially the findings of the ISSPP project. The main purpose is to review and summarize the main findings of the empirical study of successful school management. Some of these findings highlight characteristics of successful school principals that often increase their degree of homogeneity. These findings are categorized into several important principles, all of which are supported by very strong empirical evidence. The first two cases have the most evidence. The results of review studies suggest that we may need to correct and redefine today's school principals and what they are doing to achieve students' academic success

Comparison of nano-hydroxyapatite and sodium fluoride mouthrinse for remineralization of incipient carious lesions.

Dental caries is an infectious disease that can be prevented in several ways. The aim of this study was to compare the efficacy of sodium fluoride mouthrinse and nano- hydroxyapatite (nano-HA) for the remineralization of incipient caries.After obtaining different concentrations of nano-HA (0-2-5-10%), 60 sound premolars fixed in acrylic blocks were coated with nail polish except for one surface. Ten teeth (control group) were stored in distilled water and the remaining 50 samples were demineralized by immersion in 13 ml of 0.1 M lactic acid and 0.2% poly acrylic acid for 48 hours. Their microhardness was then measured and compared to that of the control group. Next, the 50 test teeth were randomly divided into 5 groups of group1 (negative), group 2 (2% nano-HA), group 3 (5% nano-HA), group 4(10% nano-HA) and group 5 (0.2 NAF mouthrinse). The microhardness of the teeth was measured after 12 hours of immersion in the above-mentioned solutions. Data were analyzed using repeated measures analysis of variance (ANOVA).Microhardness of all samples decreased significantly after immersion in the demineralization solution and increased following immersion in nano-HA and NAF mouthrinses; however, this increase was not statistically significant (P=0.711).Nano-HA and NAF mouthrinses can greatly enhance remineralization and increase tooth microhardness

Designing and Explaining of Pattern for Antecedents of Virtuous Organization at Public Universities in Yazd Province

Introduction: Organizational virtue is one of the new concepts of an organization that has received positive psychology. Researches in this area encompasses prominent behaviors in the organization, which themselves lead to positive outcomes. The purpose of this study was to design and explain pattern for antecedents of virtuous organization at public universities in Yazd province Methods: The present research is an"exploratory mixed methods research".First, the qualitative research method of "focus group" has been semi-structured interviews with faculty members of eight Yazd province universities in three sessions, 1.5 hours each.The data obtained from the interviews and literature were analyzed by the method of thematic analysis. Then the model was tested with a questionnaire and a sample of 285 employees from the public universities of Yazd province using Lisrel 8.8 software. Result: Three key factors influencing the organization of virtue were identified by the focus group and literature research and exploratory factor analysis including organizational factors; a)structure and process; organizational culture; leadership; existential philosophy of the organization, b) individual factor including: individual characteristics of employees, individual characteristics managers and c)environmental factor including socio-economic factor and legal factor). After testing the conceptual model, all the antecedents had an appropriate factor load and the model was confirmed. Also, by examining the results of the structural equation test, the organizational factor had a greater coefficient (0.74), which had the highest impact on the organization of virtue. However, the leadership factor, under organizational factor and the individual factor i.e. individual characteristics of managers and staffs have a relatively low factor load. Conclusion: Considering that the organizational factor is the most important factor in organizational virtue, organizations must pay more attention to hire of virtuous people. Theissue of educating and institutionalizing virtues in the university staffs is very important. Keywords: Virtue, virtuous organization, antecedents, pattern, university
