Introduction: The risk of being affected by infectious diseases in dentistry directly depends upon the degree of contact with body liquids, such as blood and saliva, as well as the working tools. Different micro-organisms including the viruses causing AIDS and Hepatitis B as well as oral thrush are possible to be transferred in dentistry. According to the Dental intervention (FDI), it is suggested that all dental patients, in spite of the healthy look, are considered to be infective. Therefore, the health principles and protective and safety methods must be observed in all the sequences to prevent cross-infection. Thus, the present study seeks to investigate the degree to which the dentists in Isfahan respect and approach to such standards.Materials and Methods: This is a cross-sectional descriptive study. In order to answer the questions of the study (as found in tables 1&2), the data related to the participants’ attitudes and performance were collected by having them fill out a questionnaire and a checklist. A total of 140 dentists in Isfahan were selected through a random sampling in 1385 (HS). The data collected was then evaluated with SPSS.Results: The mean score obtained from the attitude-related questions was 5.36. Also, the mean score of performance-related questions was found to be 8.03. No significant relation was found between the dentists` attitudes and the years of service (P=0.092, r=0.17). No significant relation was found between the dentists` performance and the years of service (P=0.12, r=0.15). No significant relation was found between the dentists` attitudes and their performance (P=0.1, r=0.16).

This article investigates the problem of simultaneous attitude and vibration control of a flexible spacecraft to perform high precision attitude maneuvers and reduce vibrations caused by the flexible panel excitations in the presence of external disturbances, system uncertainties, and actuator faults. Adaptive integral sliding mode control is used in conjunction with an attitude actuator fault iterative learning observer (based on sliding mode) to develop an active fault tolerant algorithm considering rigid-flexible body dynamic interactions. The discontinuous structure of fault-tolerant control led to discontinuous commands in the control signal, resulting in chattering. This issue was resolved by introducing an adaptive rule for the sliding surface. Furthermore, the utilization of the sign function in the iterative learning observer for estimating actuator faults has not only enhanced its robustness to external disturbances through a straightforward design, but has also led to a decrease in computing workload. The strain rate feedback control algorithm has been employed with the use of piezoelectric sensor/actuator patches to minimize residual vibrations caused by rigid-flexible body dynamic interactions and the effect of attitude actuator faults. Lyapunov's law ensures finite-time overall system stability even with fully coupled rigid-flexible nonlinear dynamics. Numerical simulations demonstrate the performance and advantages of the proposed system compared to other conventional approaches.

Brand extension attitude is an important marketing topic for academics and practitioners. Consumers evaluate brand extensions based on available and relevant information. The current study is one of the first attempts to empirically examine consumer attitudes toward logo and feedback effects on brand extension attitude. The impact of logo attitude on brand extension attitude was investigated by surveying the Iranian dairy industry. The empirical findings suggest that logo attitude was directly related to brand attitude and indirectly associated with brand extension attitude. Furthermore, the brand attitude had a direct positive effect on brand experience. Brand experience's role in generating both brand equity and brand strength was confirmed. It was found that both brand equity and brand strength positively and significantly influenced brand extension attitude.

However, what is considered in these explanations are the beginning of Chinese developmentalism, in fact, the end of a long-term process in the evolution of the Chinese mentality. In other words, the emergence of a developmentalist attitude in China should not be separated from the historical context and the process of its development, and it should be attributed only to the 1970s and some institutional reforms or Deng Xiaoping personal traits. Inspired by Thomas Kuhn's scientific revolutions and the introduction of the concept of " attitude paradigm", and by process exploration, this article examines the characteristics and developments of the Chinese collective attitude and mentality, especially Chinese leaders, over the past two centuries and shows that developmentalist leaders' approach of China in the late 1970s actually originated from a change in the attitude paradigm that has its roots in the developments of the nineteenth century. This shift in the mental and attitude paradigm, first manifested among intellectuals and then among Chinese nationalist leaders in the first half of the twentieth century, created a kind of developmental mentality among the leaders of the Chinese Communist Party, although in Mao and Under the influence of the prevailing ideological atmosphere, there was no way to succeed, but in the late 1970s, following the emergence of domestic and external opportunities and the displacement of elites, it became possible to succeed.

Advertising as the dominant means of communication elements, plays an important role in the success of the organization. The primary objective of this study is to explain young consumers' attitudes toward advertising. In this regard, a conceptual model to evaluate the effect of six independent variables of product information, hedonism, good for the economy, image and social role, the deviation of the values of materialism and consumer attitudes toward advertising is presented. Participants in this study were selected from among university students in Yazd. The results indicate that three of the six hypotheses, are approved. Two variables, deviated from the values and materialism have a negative impact on the attitudes of consumers towards advertising. These results will enable advertising managers to be more sensitive than consumers and to ensure that their campaigns will not adversely affect the performance of the companies they follow. These findings are also encouraging consumers to better understand their role in the purchase of advertising will help.

One of the major differences between human being and other creatures including angels is that his mentality and emotions are always evolving and growing in a sense that the essential aspect of character will penetrate into his religious beliefs. Accordingly, his way of praying whose philosophy is summarized in the verse of the Koran as “We created Jinni and other spirits to be praying” has also undergone a revolution in the form and content. In addition to keeping its essence which is worshiping God it is spiraled and engaged so much that through this kind of creature obliged to pray in different forms of life other creatures should find out and make a research on various aspects of different means of praying and spiritual journeys.Now we would like to recognize the means of spiritual journey and internal ways of praying by the Egyptian IbnFarez. He lived in an era that the praying of some devotees had exceeded the normal situation and turned into abstinence and wayward to God during the first century, then to spiritual journey at the outset of the second century, after which by the late third century toward a phenomenon of fatality and revelation and unity, and eventually to the monism or intuition and hidden concepts of that in the seventh century.Therefore, it is endeavored to study and analyze the mystical view of his. After the introduction on training Sufis and the available expressions used in that era, there will be some explanation on his mystical concepts and then the nature of his love and the procedures. In the end, the comments of some researchers on the nature of unity and his views on revelation and monism will be dealt with.
