This article seeks to identify and formulate the epistemological foundation of the Muslim experts' ideal. The ideal in Iran, especially after the Islamic Revolution, was raised as a solution to the gap between seminary school and university. However, this ideal has been pursued by administrative plans and regulations, religious programs, documentation, and focusing on institutionalization, organization, and council. This research which was conducted using a library method analyzed Weber's theory of knowledge and value. We argue that the Weberian distinction between value-relation and value judgment can be used by Muslim experts as a base. Accordingly, to this distinction, the engagement of religious and cultural values of Muslim experts in academic and non-academic activities is legitimate.

Background: Socio-economic factors, following psychological factors, affect the value of children in parents’ view and this value itself could influence Ideal Number of Children (INC), which is one of the most important dimensions of fertility behavior. The aim of the present study was to investigate parents’ INC according to the factors influencing the value of children from the viewpoint of men and women, separately.Methods: In a cross- sectional study, multi- stage stratified sampling method was conducted to collect data from 590 males and 610 females in Tehran province, Iran, using a questionnaire including demographic and attitudinal questions. To describe data, SPSS-17, and to examine the factors influencing INC, path analysis was used in AMOS 22 and Goodness of fitted model was approved using the relative chi-square (c2/df), Goodness of Fit Index (GFI), Adjusted GFI (AGFI), and Root Mean Square Error of Approximation (RMSEA) indices.Results: Indices of Goodness of fit confirmed the fitted models (c2/df=2.289, GFI=0.994, AGFI=0.973, and RMSEA=0.047 for males’ model and c2/df=0.511, GFI=0.989, AGFI=0.994, and RMSEA=0.020 for females’ model). Negative psychological (males’ coefficient=-0.20 and females’ coefficient=-0.17, P<0.001) and positive economic (males’ coefficient=0.11 and females’ coefficient=0.09, P<0.05) factors of children values were both significant on INC based on gender. Moreover, negative social factor (males’ coefficient=-0.26, P<0.05) of value of children was significant on INC only for males. These significant factors had higher impacts on men's INC, as compared with that of women.Conclusion: According to the results of the present study, significant factors influencing INC of males and females were negative psychological and positive economic factors of the value of children and the negative social factor of value of children was the only significant factor influencing INC for males.

Future and ideal are something problematic now more than every day before. In this frustrating fog occupying everywhere, all attempts have been assigned to individual needs, personal successes and close future. Collective ideal and far future have become secondary goals. In such conditions “, self”,will cut its ties from social context, will alienated from the society, from history and from itself and will tend to reification. What role university and academic training will play here? The specific question of this article is how each of the two approaches of natural sciences and human sciences will relate in this alienation? Social faculty of Tehran university has been selected as representative of human sciences and engineering faculty of Tehran university as representative of natural sciences. 15 students of each faculty were interviewed about their ideals, wishes and futures. According to the results, linear determinative scientific causal law dominated on natural sciences in engineering faculty will permeate to the world of human relations. In the sphere of these disciplines society is not an independent totality but just sum of the singular individuals. Ideal and future have seen as not more than just personal success. In contrast in the fluid and multi-paradigm world of human sciences, relation between individual and society will be understood as complicated, multilateral and dialectical. Personal success and collective ideal will be seen as interwoven,and ideal will not know as just personal success inside the status quo, but the will of the change in the status quo itself.

Introduction: This study evaluated the degree of micro leakage of Ideal Makoo and Tetric Flow composites using two dentin adhesives of Scotch Bond Multipurpose (SBMP) and Excite.Materials &Methods: 60 premolar teeth were divided in to four groups of 15. and class V cavity preparations were done in CEJ. Group 1 was rest orated with SBMP and Ideal Makoo, Group II with SBMP and Tetric Flow, Group III with Excite and Ideal Makoo, and Group IV with Excite and Tetric Flow. Stereomicroscope (X40) was used to evaluate and dye penetration in occlusal and gingival margins. Chi Square test, Pearson’s correlation test and Fishers exact test were used for data analysis (α= 0.05).Results: 1- The degree of leakage was not in correspondence to the type of composite.2- The degree of leakage was not in correspondence to the type of dentin adhesive.3- In four groups, the degree of leakage in gingival wall was significantly more than occlusal wall.Conclusion: Type of composite and dentin adhesive have no effect on degree of leakage. The important factor is the type of wall. It means that in class V restorations, gingival wall is always observed to have more micro leakage than occlusal wall.
