Backgrond: One of the concerns faced by dentists is the reliability of tooth shade SELECTION. The present research was carried out concerning the increase in patients’ expectation of beauty and the importance of conformity in restorative materials for success in beauty restorations and also due to the lack of suffecient research in this field. The current study was performed to determine the reliability of tooth shade SELECTION done by the students of semesters 11-10 using vita Classic system at Tehran Islamic Azad University, School of dentistry, in 2015. Materials and Methods: A cross sectional study was carried out on 60 students of dentistry who had no COLORblindness. Ishihara COLOR-blindness test was taken from all of the students and then they were asked to choose the COLOR of patients’ left maxillary central incisor using four vita Classic shade guide kits with unknown codes. In order to unify the condition, the patient was asked to brush her teeth and remove her makeup. The light was assimilated using “ day light” device made in Taiwan and also tooth shade SELECTION test was done in 30 centimeters distance from the patients and no time limitation. A grey screen was used to prevent eyestrain. After 10 days, the experiment was repeated with similar conditions. Results: The reliability of shade SELECTION in students (R) was 0. 96 or %96 and the congruency (R² ) was 81 percent. Also, %65 of excellent reliability and %24 of good reliability and 8 moderate reliability and %3 of low reliability was observed among the residents. Relevant factors like gender, wearing glasses, and academic semester were not observed to be statistically significant (p<0. 2). Conclusion: It saems the there is a high reliability of shade SELECTION in students and it does not have any relationship with other factors.

COLOR is one of the main indicators of aesthetics issues. Due to importance of COLORs quality among the industrial products, COLORs SELECTION for products is a key point for production. Furthermore understanding and conceptions of the mentioned visual factors is complicated. Also, COLORs as a very important aesthetic factor is a challengeable and effective subject for design’s team work and their innovations, thus the main manufacturing companies around the world have R&D departments which studies about COLOR in products, specifically. COLOR SELECTION and make an effective harmony among the different COLORs is one of the most important activities in industrial design discipline, besides industrial designers are facing with the mentioned area. They also pay attention to COLORs functions and effective in everyday products, more than other experts.Taking and choosing of COLORs will be based on two approaches: “technical field” and “interface scope”. In the first one some subjects are studied such as chemistry of COLORs, kind of COLORs and surface absorbance, and so on. In the second scope, relationship and connection between human and environments will be discussed. However, the second area is more important because it is related to human needs. In this study importance of COLORs and COLORs’ roles in surface features among the products were studied. Also COLORs were introduced as a key element for users and their behaviors for purchases. All in all the findings of this study emphasize on this fact that choosing of COLORs for products design is a wide scope which covers a multidisciplinary function.

The study examines the SELECTION of COLOR (car and road) to modify driving behavior of traffic users with the aim of providing executive strategies for changing traffic behavior of users. The author believes that it can be achieved using cultural approaches and attention to the COLOR factor in the car and the road or behavior change to improve the traffic behavior and reduce the driving accidents. For this purpose, the researcher used a survey method to collect data. In this method, experts' opinions can be used to evaluate the indicators of traffic behavior change. By this description, the method of this research is a survey and practical in terms of purpose and. The statistical population of this research has been the experts and elites of traffic management areas. The data collection tool was also maed by a researcher-made questionnaire that its validity and reliability were confirmed before the implementation. Data was also analyzed using Pearson's test. The results of the research show that, all of the hypotheses are meaningful In Pearson’ s test and it can be stated that are correlated between the type of COLOR application in terms of the optical spectrum – the role of car COLOR in the control of the emotions-the role of road COLOR and proper alignment-the role of COLOR in reducing the fatigue and proper driving-the COLOR of the COLOR in setting aggression patterns in driving and the role of advertising and informative COLORs and reducing driving errors in the four bases of landslides-Intentional violations-unintentional violations and reduction of driving errors.

Purpose: Managers are one of the important elements of an organization, for this reason, in order to draw the future of the organization, it is necessary for the planners to specify the conditions of their SELECTION and appointment. Therefore, the current research has been done with the aim of identifying and analyzing the components of selecting future principals.Method: In this research, comparative and benchmarking method is used as a prospective approach. This approach is based on the belief that today's advanced organizations/countries can be considered as a model for the future of another organization/countries in their respective subjects. For this, first, the fields of comparison and benchmarking were determined using Brody's four-step comparison method; then the countries of Canada, Finland, Australia, South Africa, and Japan were selected according to the qualitative balance value in the international advanced TEAMS test, human development index, life quality index(health, instruction, and welfare), education quality index, and other scientific-scholarly indexes; finally, by extracting the criteria for the SELECTION and appointment of principals through content analysis and comparison with Iran, the proposed framework for Iran has been presented.Findings: A total of 61 components for the SELECTION of secondary school principals were identified from among the studies conducted in the selected countries in this article. By extracting the commonalities and differences of each of the components among the countries, it was found that the highest index of manager SELECTION and appointment belongs to Japan and the lowest one is related to Finland.Conclusion: There are similarities between the components of SELECTION of principals of secondary schools in Iran and selected countries. In Iran, special attention should be paid to important components such as adherence to religious principles, appropriate personality traits, creativity and innovation, motivation to develop capabilities, professional growth, power of supervision and accountability, social image, leader skills, and purposefulness and foresight.

Trichogramma brassicae Bezdenko (Hym.: Trichogrammatidae) is one of the most widely used parasitoids of lepidopteran key pests around the world. This species has two reproductive modes, arrhenotoky and thelytoky, the second one is caused by an endosymbiont bacterium which is called Wolbachia. COLORs have been mentioned as one of the factors which influence the oviposition of parasitoids. The present study examined the effect of the COLOR patch and quality on oviposition of Wolbachia-infected and uninfected T. brassicae population. At the first, sterile eggs of Ephestia kuehniella Zeller (Lep.: Pyralidae) as laboratory host of both populations were glued on COLORful patches included; blue, green, yellow, orange, red, and white, with 30 repetitions for each populations. COLORful papers and cellophanes were used as patches. Both cardboard and cellophane patches were placed in an equal distance from each other in cylindrical containers. All females were separated from E. kuehniella eggs after 24 h. The results showed significant differences in the oviposition rate of infected and uninfected T. brassicae on COLORful papers while there were not any significant differences in the oviposition rate of both populations on COLORful cellophanes. The results showed that asexual and sexual populations responded differently to COLORful papers although females of both populations were able to discriminate between the COLOR of paper patches.

Aesthetics has many components, the most important of which is design and COLOR. One of the most beautiful elements in the kitchen is its cabinets. This beautiful element, in addition to its application, plays the most pivotal role in shaping the interior decoration of the kitchen with COLOR and design. This study investigates the aesthetic effect of the design and COLOR of wooden kitchen cabinets in its SELECTION. The research method of this article is analytical-descriptive, survey and field. The statistical population and data collection and completion of the research questionnaire is the users and manufacturers of wooden cabinets in Ardabil province. In order to determine the effect of the independent variable of design aesthetics and COLOR on the dependent variable of wood cabinet SELECTION, linear regression equation has been used. The results showed that the value of multiple correlation coefficient of COLOR aesthetics regression model in wood cabinet SELECTION is equal to 0. 941. The choice of COLOR based on the natural texture of wood is 0. 800 and most changes are dependent variables. The value of multiple correlation coefficient of the aesthetic regression model of the form is equal to 0. 934. The variable of non-geometric shapes with the value of Pearson correlation coefficient of 0. 679 is the first priority among the aesthetics of the design and it can also be said that there is a significant relationship between the two variables studied the study. The sign of the correlation coefficient is positive between the two variables and therefore they have a direct incremental relationship with each other.
