Suitable utilization of daylight in architecture, in addition to meeting the physical and emotional needs of human increase the quality of living spaces. From this perspective, our country's rich architecture has valuable achievements and experiences, which requires recognizing and introducing it to the architectural community of Iran and the world. The present research intends to examine the various qualities made at the back of light entrances using descriptive-analytical method, field observation and study on library documents and obtain the factors contributed in creation of these qualities and take step to reuse these ideas in modern architecture.

Value stream mapping because of being able to understand process bottlenecks, as one of the most common tools for analyzing, identifying and eliminating various losses in operational and support processes are used. On the other hand, inventory management, precise control entry and exit of goods, accurate and timely information about the inventories status and planning, reduce product maintenance costs, including important issues organizations have a special look to it to consider the whole objectives and strategies, making procedures and policies that have a positive effect on the overall organization’s economy. In this paper, the use of value stream mapping as a lean production technique, in a production process to improve inventory control is discussed. This is a tool seeks to reduce losses, especially losses related to inventory by mining a bearing manufacturer companies. In this study, the literature of value stream mapping considered. The current state and future state of the company drawn in order to improve production process and losses in the company's future status. In addition, after drawing the mapping, the results of the simulation software Arena and the final report suggests that the use of this technique has an impact on reduce losses and increase inventory turnover.

Widespread usage of web technology provides an opportunity for business in order to use internet as the tool for management of electronic relationship with costumers. Organizations that undertake expense of investment in this field, one of their primary purposes is improvement of satisfaction of costumers. For this reason, in most of organizations which use the system of electronic relationship with costumers, there is this question that does this action affects customer satisfaction or not? Therefore, it is determined that this question and dimensions of customer satisfaction are considered in research project. The present research is functional in terms of the purpose. The results of research, after collection of data and analysis by using LISREL software shows that electronic management in factories affects satisfaction dimensions of after-sale services, product and sales process.

A sensitivity analysis of the flood safety of Solaimantangeh dam using a regional climate change simulation is presented. Based on the output of the CCSM (Community Climate Change System Model) general circulation model, the NIRCM (North of Iran Regional Climate Model) computes regional scale output with 50 km spatial resolution and 21 vertical layers. Using the SRES (Special Report Emission Scenario) “B1” Climate Change Scenario when applied to the Tajan river basin, where Solaimantangeh dam is located, NIRCM reduces significantly the bias in Annual Maximum Event total Precipitation (AMEP) & Annual Maximum Daily Precipitation (AMDP) that CCSM shows. The stream flow change scenario is then simulated using SSARR (Stream flow Synthesis and Reservoir Regulation) model. A rainfall-runoff model was implemented using precipitation and temperature projected by CCSM and NIRCM. The model demonstrated that average Stream flow would increases 38.7% and the variability would increases 14.3%. This remarkable increase in projected annual maximum flow for the next 20 years (2004-2023) should be a significant negative signal to water resources managers. The results indicate that the number of floods remains almost the same, but that the magnitude of a single flood event and the recovery from it become worse.

Nowadays, one of the topics of interest to researchers is the authority of teachers, and fades it in universities. Look at the reality in the society and comparing with historical context motivates researchers to question why some of the professors at the university have less authority. For this purpose, this research is trying to focus on economic and demographic factors, to answer questions. The method used in this research is descriptive analysis using survey techniques and data collection tool is a questionnaire. The population consisted of professors of Kermanshah PNU in the academic year 2011-2012, total number of them is equal to 258. Due to the large size of the population, using the Lin sampling table sample size is 258, which for the study based on striated random sampling were selected. In the present study, face validity assessment method and construct validity based on factor analysis were used. To determine the reliability of the statements of each variable, Cronbach's alpha used. Results using SPSS21 and Amos21 statistical software were analyzed. Mean traditional authority equal to 13.57, then charisma authority13.54, and intellectual authority is 18.72. The dimensions compared with the average expected for above dimension respectively traditional authority 15, charisma authority 12, intellectual authority is 15. The results show that there is a significant relationship between relative deprivation and professor’s authority (r=-0.301), the use of mass media and professor’s authority (r=0.161), monthly income and professor’s authority (r=-0.153). In addition, the results of comparison show that average of the professor’s authority among the courses is different, and this difference based on f test is significant. The average professor’s authority, for people with different degrees is different. The results of Multiple regression indicate that the traditional authority (T=4.335), self-esteem (T =3.925), charismatic authority (T =3.788), and the relative deprivation (T =-2.287), total 0.42 from internal changes explain the value of professor’s authority variables. Furthermore, the results of structural equation shows that Chi square insignificant CMIN is equal to 211.143, square root index mean residual square or RMSEA is equal to 0.075, RMR index or residuals mean square root is equal to 0.098, the Chi-square to the degrees of freedom ratio CMIN.dF in model is 3.199, against the CFI comparative fit index 0.926, and comparative fit index thrifty PCFI, are equal to 0.671 Comparative and thrifty indicators for evaluating the overall model calculated that show collected data to support the theoretical model considered.
