The vast expanse of the urban distressed areas in the country and multiple damages that their inhabitants face on economic, social and cultural aspects remind the need for higher attention to these constructions. Meanwhile, Tehran's distressed areas with more than 3268 hectares (5.3% of the area of ​​Tehran) has a population of one million and three hundred thousand people in it, is one of the priorities of the improvement and renovations in the country. According to what most experts and researchers say one of the main obstacles to the process of improvement and renovation of the urban distressed areas, is the selection and use of appropriate methods of financing. Several methods of financing that have been raised to be used in the process of improvement and renovation, on one hand due to the variety they provide are an opportunity, and on the other hand face the managers and city decision-makers with some problems in the process of selection and utilization, because using any of the methods depends on several regional and local factors. In this regard and in order to facilitate the process of decision-making in the process of improvement and renovation of urban distressed areas, this research used a cross-sectional study and also investigated the evaluation criteria and different methods of financing the distressed areas and using the obtained field data from questionnaires distributed in two stages using ANOVA test, tested the research hypothesis in order to determine the best financing method according to the improvement and renovation process from the perspective of the tested criteria and in this way tried to compare the various methods of financing in order to take advantage of the process of improving and renovation of urban distressed areas in Tehran. In this regard and based on the obtained results three methods of repayment from the operation of the project, civic engagement (contract) -guaranteed and selling shares were identified as ways with the highest priority to utilize in the process of improvement and renovation of the urban distressed areas of Tehran.

Concurrently, organizations must respond effectively to social expectations and moral law and to achieve success in all areas and by respecting professional ethics adopt an appropriate procedure to achieve these expectations align with organizational goals to facilitates promotion of social accountability and realization of higher goals. In this study, we have formulated a framework by reviewing the literature and related researches so that with application of quality and quantitative combinatory approch as well as utilization of Delphi and judgmental sampling and chain and professional acceptance of scientific and organizational model (32 members), a comporehensive model was instituted in the form of a standard model (individual, organizational and cross- organizational) and 23 indicators of professional ethics to promote social accountability. Then, realized model structures in the studied organizations has been tested through structural equation modeling (confirmatory factor analysis) using smart PLS software. Meanwhile, Cronbach's alpha (0.965) is used to measure questionnaire’s reliability in addition to evaluation of validity. Moreover, among national executive accountability, 124 members are selected for this study through Morgan table and stratified random sampling method so that the situation of each dimensions such as individual (3.56), organizational (3.50) and cross-organizational (3:06) were obtained unfavorably. Overall, this study defines a new method to analyze and measurements of enhance public accountability and professional ethics under Iranian’s government agencies.

Recreation (creativity) is undoubtedly one of the important designing bases and a durable, matchless and unique factor which determines distinction, excellence, and elegance of a building in comparison with other buildings; and architecture as one of the manifestations of human life in a special time and place can be a reflection of thoughts, ideas and living method and also represent identity in shape of thought and creativity which is known as creator of architecture work from viewpoint of architecture. Firstly reflection of architect’s character in architecture work, then cultural concept of the work and its belonging to a specific social and ideological movement and besides talent and creativity of the artist, the cultural and artistic movements affect drastically on the result of architect’s act who is creator of the art work in form of an architecture event. Therefore it can be mentioned that variables of the present research are nominal and qualitative; the dependent variables are also of the same type. The effects of economic, political, social and cultural movements can also be mentioned which are expressed in form of concepts such as tangible and intangible strategies. The present paper attempted to analyze metaphors used in the major building of Behsharh Industrial Group, which is an objective evidence of Nader Ardalan’s work. The analysis was done in a historical-interpretation method and in qualitative form.

No unique method has been so far specified for determining the number of neurons in hidden layers of Multi-Layer Perceptron (MLP) neural networks used for prediction. The present research is intended to optimize the number of neurons using two meta-heuristic procedures namely genetic and hill climbing algorithms. The data used in the present research for prediction are consumption data of water subscribers in Fasa City of Fars Province (Iran) between the years 2010 to 2013. Ultimately, using the respective data set, the data of the subsequent year 2014 can be predicted. In the present research it was observed that the mean square errors of per data (MSEPD) for the abovementioned algorithms are less than 0.2, indicating a high performance in the neural networks’ prediction. Correlation coefficients using genetic and hill climbing algorithms were respectively equal to 0.891 and 0.759. Thus, GA was able to leave a better effect on optimization of neural network.

This research seeks to determine the dimensions of organizational forgetting management and prioritize them in university. Current research in terms of purpose is applicable. In terms of data, it is quantitative. In terms of method, it is a descriptive-survey research. In this research, for determining the validity of measurement tool, content validity has been used and for calculating the reliability, Cronbach's Alpha method has been used. The population of this research includes the faculty members and employees of Islamic Azad University in region 8. Also the researcher-made questionnaire has been used for information collection. In this research, a framework consisting of quadratic dimensions of the process management, technology, culture and structure for evaluation of organizational forgetting management was considered. With regard to the comparison by using of the mean index, the quadratic dimensions were evaluated in two eligible and available situations. It is determined that with regard to the difference between two available and eligible situations, in fact the level of process dimension is low and it is in available situation, also it can be concluded that culture in available situation is very posterior than ideal and eligible situation. In two technology and structure dimensions, this mean difference is less than two other dimensions. In available situation, the most gaps and deficits at first exist in culture dimension and then in two technology and structure dimensions; and finally there is weakness in the process dimension. Totally in different dimensions, there is a relatively large difference and gap between the mean indexes of two eligible and available situations.
