Background and Objective: In Islamic architecture of Iran, public buildings such as mosques-schools were places for people to interact with different tastes and thoughts, with their diverse functions and spaces and with in-between spaces that played a decisive role in organizing the diverse functions of these places and linking them more closely. They formed a whole, and made it possible for one to stay in that place. The purpose of this study is to investigate the effect of the in-between spaces on promoting a sense of place in the Qajar mosque-schools and to explore how in-between spaces can be effective in promoting a sense of place?Methods: Correlation analysis in Spss software was used to analyze the variables, and with library, field and survey studies to investigate the effective factors in promoting sense of place and in-between spaces.Findings: Results of this study indicate that the coefficient of significance between the variables of sense of place and in-between spaces is less than 0.05 and there is a significant relationship between these two variables.Conclusion: The use of in-between spaces can be effective in creating sense of place in architectural space. Because today the concept of in-between spaces is very important in the design of architectural spaces, so that it can be used to reinforce the link between human and place in new public spaces, ultimately leading to better exploitation of the environment and the continued presence of people.

Abstract Background and Objective: Synthetic dyes are prevalent pollutants and one of the most resistant pollutants in the environment. Developing a simple and effective method to destroy non-biodegradable pollutants is one of the major challenges in environmental studies. The aim of this study is to evaluate the efficiency of the polyaniline/ wheat bran composite in the removal of acid red 18 dyes from aqueous solutions.Method: In this study, removal of acid red 18 from aqueous solution using wheat born loaded by polyaniline was investigated. For this purpose, composite synthesized through in-situ polymerization processes. Adsorption experiments were performed in batch system at laboratory scale .The effects of various parameters including the amount of adsorbent, pH, initial concentration, temperature, and contact time on adsorption were studied. Further kinetic and thermodynamic studies were performed on the data.Findings: The highest absorption rate by 0.1 g of adsorbent was equal to 100% at pH =2 of the solution after 2-hour contact with absorbent. The results show that the kinetic pseudo-second-order model fits the data. The experimental data were adjusted with Langmuir model.Discussion and Conclusion: According to the results, a simple, economical, and efficient method wasPresented to remove biodegradation-resistant pollutants using polyaniline/wheat bran composite.

AbstractThe Department of Environment is the main custodian of environmental protection and the implementation of Principle 50 of the Constitution. The accuracy of the organization's performance shows the failure of the full and effective implementation of the assigned tasks, which has provided the ground for raising the issue of forming the Ministry of Environment. Proponents of this plan express Reasons like Creating integration and managerial cohesion, structural weaknesses and shortcomings of the legal system and lawful parliamentary oversight and opponents point to the confusion of sovereignty and entrepreneurship, the weakening of the main task of the institutions subject to merging and their different positions, and the difficulty of managing a multi-sectoral institution difficulty of managing a multi-sectoral institution. The present study, with its descriptive-analytical method, seeks to examine the possibility of forming the Ministry of Environment in the Iranian legal system. Studies have shown that fundamental legal problems such as the lack of a comprehensive sustainable development plan and environmental protection developed based on the general policies of the environmental system, as well as the existence of parallel, scattered and old rules and regulations lack comprehensive and systematic approaches to environmental management, affects the management of the department or ministry, and they must be addressed first. However, given the ministry's organizational, social, and legal status in the country's political system, the Ministry of Environment's structure seems to be more successful in creating and implementing these fundamental changes and solving existing problems.

Context and purpose: The purpose of this study is to identify the effective and determinant factors in the feasibility of establishment of occupational health and safety management system in Iranian governmental organizations. This type of research is a developmental application.Method: The statistical population of this study consists of two groups. The first group consisted of 30 experts and the second group consisted of all employees of governmental organizations in Kerman province with 77528 persons that the sample size in this area was determined using Cochran formula of 384 individuals. The research instrument is a researcher-made questionnaire on the feasibility of establishing an Occupational Safety and Health Management System whose validity has been confirmed by experts and its reliability has been confirmed in order to Cronbach's alpha value for feasibility variable for occupational health and safety management system deployment is 0.986. Data were analyzed using SPSS software and Smart Pls. Findings: The findings of the study indicate that intra-organizational and intra-organizational contextual factors and their components have a favorable status and their impact on the feasibility of establishing an Occupational Safety and Health Management System is positive and significant. Technological and temporal factors had the highest ratings with external ratings of 5.09 and 4.56, respectively, and leadership and information style factors with the average ratings of 5.82 and 5.78, respectively, they were the highest among the factors within the organization. Conclusion: Considering the factors considered in the present study and considering the strengths and weaknesses of these factors can greatly clarify the path towards the establishment of occupational health and safety management system in Iranian governmental organizations.

Increasingly population and erection of high-rise buildings have multiplied the environmental pollutants in cities. This is while individuals use open urban space more than before to obviate their living requirements. Various factors such as the building layout and the continuous existence of wind can play a significant role in the dispersion of pollutant particles. This study was conducted in this field and its goal was a survey on the impact of high-rise residential buildings layout on the way pollutant particles are dispersed via the cognition of Tehran’s airflow. In this research, the wind behavior around the buildings and pollutant dispersal are analyzed by descriptive-analytical and comparative methods and utilizing the simulation technique with software ENVI-met. The method of information accumulation has been library studies and field research. According to the modeling of the two different types of layout of selected urban block (Sobhan residential complex in Gheytariyeh district, Tehran) with similar building form –one as the existing situation and the other as the proposed model with orderly layout, the findings demonstrate that the layout alternation of residential blocks affects the natural airflow and wind speed between blocks and an improper and non-methodical locating of high-rise buildings causes a change in natural wind pattern and consequently, leads to secondary effects resulted from intensification or stagnation of wind and thus, influences the dispersion of pollutant particles. In this research, the obtained results from the two models of buildings layout in the software and the outputs related to the intensity of wind and the retention level of CO show that the existing situation model is more desirable compared to the proposed layout due to more unified and higher wind speed throughout the site and also proper air circulation between blocks which causes the dispersion of pollution and prevents the retention of pollutant particles.
