Industrial ecology is the identification and application of solutions aimed at reducing the environmental effects of products and processes of industrial systems. Industrial symbiosis is a practical application of industrial ecology where manufacturing companies cooperate by creating a network in the field of local exchange of water, energy, or industrial waste recycling. Industrial symbiosis plays an important role in reducing total costs in green supply chain management and its sustainability. Previous researches in the field of green supply chain management have somehow improved its performance by using different tools, but less on the impact of the new and effective industrial symbiosis concept has been discussed. In the current research, for the first time, a mathematical model is presented to apply the concept of industrial symbiosis in green supply chain management to minimize total costs with minimal carbon emissions. The proposed model is a multi-period single product and the lack of demand is allowed. To validate, the proposed model was used in the steel industry with 30 factories during 22 planning periods and with 15 types of raw materials. GAMS software is used to solve the model. The results of the numerical solution of the model have the greatest reduction of carbon emissions and adverse environmental effects with minimum total costs in factories. The sensitivity analysis showed that the value of the objective function of the model is high in relation to the changes in the parameters of the amount of the reproduced product, the rate of the collected return product, the amount of the returned product, the rate of the final disposed product, and the penalty for exceeding the permitted carbon emission limit. The results showed the alignment of green supply chain management policies and industrial coexistence.

The purpose of this study is to explain the impact of green supply chain on economic performance, emphasizing the mediating role of green innovation, environmental management and quality management in companies listed on the Tehran Stock Exchange.

In this research, the multivariate perceptron neural network approach and modeling of variance-based structural equations in SPSS26 and SmartPls3.3.3 software have been investigated.

The results show that green supply chain management affects economic performance and increases green innovation, environmental management and quality management of economic performance. The establishment of a green supply chain has led to the observance of environmental requirements, and by observing environmental requirements, labor productivity is improved through specialized training of employees.

 In previous studies have not considered the pros and cons of the relationship between environmental management and labor productivity. In this study, according to the selection of companies listed on the Tehran Stock Exchange during the covid-19 period and the statistical sample selected by systematic elimination method and available sampling, these views were examined. Also, in the research method, most researches have only fitted the model with structural equations and regression equations, while in this research, the proposed model fits with multilayer perceptron neural network method and variance-based structural equations and finally to evaluate the performance prediction comparison model. Economically, the root mean square error index is used

AbstractBehavior in the workplace is affected by various variables, but the relationship between these variables and the safety, health and environmental behavior of individuals is not definitively confirmed, or even possibly in all industrial societies and diverse industries with different cultural characteristics is not confirmed. The purpose of this study was to present a health, safety and environmental management model to improve employee behavior. The statistical population in the qualitative part are HSE specialists and experts of Tehran Municipality and in the quantitative part are the executive staff of Tehran Region 7 Municipality. In this study, library studies and Delphi technique were used to identify individual and organizational factors affecting employee behavior correction and to investigate the impact of these variables on employee behavior correction and provide a model of health, safety and environmental management a questionnaire and structural equation technique with Smart-Pls software was used. The results showed that among individual factors (attitude towards behavior, awareness and knowledge and Risk perception) and among organizational factors (management commitment, safety atmosphere, organizational culture and effective communication) are effective in improving the behavior of executive staff of Tehran Municipality. The results of this study can be used in the continuous improvement of health, safety and environmental management.

The green construction industry has been emerged with the urbanization development, the global populatation growth, and growing demand for more sustainable and eco-friendly structures and it has been expanded quickly regarding some benefits such as energy and resources saving, less greenhouse gas emissions, and optimizing the health of residents. The urban development and planning based on green buildings is more complexed compared with the one based on regular buildings, and as a result, it seems necessary to design the accurate and comprehensive planning for identifying risk factors for the success of green buildings projects. This study is presented with the objective of the identification and evaluation of the risk for green buildings based on a real case study in the city of Shiraz. To this end, based on the opinions of experts team including consulting engineers, designers, executors, contractors, and the literature review, 17 criteria are identified as the most important factors and they are classified in 5 groups including policies and standards, economic factors, environmental factors, management factors, and technical and quality factors. The relationship between risk criteria and sub-criteria is studied with DEMATEL procedure and the ranking of risk criteria is done by applying the analytic network process (ANP). The results show that government policies and complicated approval procedures, the project delay, the lack of specific insurance for green buildings and the lack of accurate estimation of investment returning are the most important risk factors of green buildings that urban designers must focus on them to increase the successes of the new emerging green construction industry.

Today, organizations and projects managers perceive the changes of world. Hence, they distanced away the traditional organization management and oriented toward the application of novel management principles using the promotion patterns in organization. Accordingly, in present research, the health culture promotion pattern, safety and environment in project-based organizations are studied using EFQM in a contracting firm. The methodology in this research is descriptive-correlative. In addition, the library research was used to collect the information about foreign and local literatures. The population includes 400 experts and practitioners in health, safety and environment related occupations among with 118 subjects were selected as the sample size using Cochran's formula. Moreover, using the SPSS and LISREL, the data was inferentially and descriptively analyzed. The results implied that applying the organization promotion model is effective on health, safety and environment promotion in project-based organizations.

Nowadays, Due to the industrialization process of human societies, Safety experts working on the safety new management and systems to reduce the incidence and severity of possible accidents. Therefore, safety culture promotion is considered as a special approach to HSE management. The aim of this study was to collect information about HSE culture in an electric power distribution and transmission company and to offer recommendations to reduce the probability and severity of accidents. This cross-sectional study was conducted on 130 employees in the company applying questionnaire of HSE culture in 2013. The Likert's scale was used to evaluate scores. Statistical analysis including T-test, ANOVA, correlation coefficient and variance analysis was applied to assess and analyze data. The study showed that average of ages and experiences of studied employees were 31.52±7.01 and 8.51±6.71 years, respectively. The mean score of the company's safety culture was 182.7±14.821 that the contribution of people with negative safety culture (scores below 177), was 38.5%. There was a significant relationship between safety culture and accidents with experience and also between accidents with job (p<0.05). Education is the most important factor to improve safety culture in this study. Training should be considered for all jobs and for employees with any level of education and incident.

The technology، after the outbreak of industrial revolution and the far-reaching changes of twentieth century، entered the human life rapidly and changed it substantially. The human utilized different technologies day by day with a motive of achieving more welfare and security، and after a while the technocracy was considered in human societies; in such a way that tools found key role in his life little by little. Human expectations in all fields were gradually answered by technology، thus technology (technology exclusiveness) found its way out. At this time، technology removed the tradition and culture from human lives unnoticeably and replaced all key words of their lives by the definition as it prefers. Therefore، it leads to the point where technology took over the role of God، and the human was caught in that trap completely. Subsequently، all aspects of human life such as culture، environment، employment، economy and any other imaginable areas were influenced deeply by technology، about which we interpret it as a «technology trap» which is the subject of the present article. To face this far-reaching development and not to be caught in this sparkling trap، there are some methods، for sure. Accepting any technology is not necessary، but the very determining factor is the spiritual nature and believes of the society into which the technology enters. By removing the unsuitable aspects of the new technologies، any society can use them based on its valuable cultural، historical and religious backgrounds. In this article، having presented the technology definitions، the dominant conditions of today''s world in facing the widespread phenomena of technology are studied. Finally، in order to prevent from being surprised and the consequences arising from unquestioning acceptance of different technologies، some methods for evaluating and foreseeing the technology are presented. Therefore، utilizing the technology in architecture can be done suitably and selectively in any society.
