The construction and civil operations function is at the forefront of adventurous activities in most countries of the world due to its expansion. The existence of various hazards and harmful factors in construction workshops has made this industry one of the most risky industries in the world. This issue has been considered in our country as well as other developing countries. Protecting human lives is first and foremost the most important issue in any work environment. This is an urgent need for great attention and implementation of the necessary requirements in order to save human lives. Manpower is the capital of any organization that in case of endangering their lives, performance and ultimately achieving the goals of the organization or community is challenged. Due to the importance of HSE in various industries, especially the manufacturing industry, this study was intended to examine the factors affecting safety, health and the environment. This was done from a qualitative and quantitative approach. In the qualitative approach, unstructured interviews were used to collect data and in the quantitative method, a questionnaire was used. The data received from the questionnaires were analyzed with Excel software and TOPSIS method to determine the weight and priority of the identified factors. According to TOPSIS surveys, the status of safety and firefighting equipment weighing 0.095, HSE checklist weighing 0.081, manpower status weighing 0.076, having direct contact with staff and discussing HSE issues weighing 0.073 and records and indicators Contractor HSE performance with a weight of 0.065 are five important and influential factors in safety, health and environment.

The present study is an attempt to examine the health status and socio-cultural conditions in urban parks (Case study: Izeh city parks). This research is applied in terms of its objective and descriptive-analytical in terms of research method. The required data are collected through documentary-library surveys and field studies. Findings are analyzed using descriptive and inferential statistics in SPSS20 software. The statistical population of this study is the total population of Izeh city and the sample size is estimated to be 391 people using Cochran's formula. Then, using the survey method and questionnaire tools, the required information is collected from the visitors of Izeh city parks. The results of the questionnaire using a one-sample t-test show that among the health, social and cultural indicators, socio-cultural and health indicators with averages of 2.43 and 1.86 are in the best to the worst conditions, respectively. Also, the results of the questionnaire using the One-Way ANOVA parametric test show that among the 10 parks in Izeh (parks studied in this study), Shadi, Shahr, Sultan Dinavar, Azadegan, Shahrbazi, Banoo, Sakhrei, Valiasr, Baharan and Laleh are in the best to worst conditions with averages of 2.27, 2.26, 2.24, 2.23, 2.22, 2.21, 2.19, 2.18, 2.17, 2.10 and 2.2 (according to normal average 3), respectively. Moreover, none of them have normal health and socio-cultural conditions. This indicates the poor performance of Izeh urban management in both sections.

There are many factors which may cause victory in an organization while different concept of victorious might exist  depend on the organization. One of the impressive one is efficiency which is not  related to organization type and each management unit must consider methods to increase efficiency. Ergonomy will be effective to efficiency index growth, cause better function in every organization. Ergonomy principles incorporate ways which can protect people mental and physical  heath, also motivate employee. These principles could  lead  person to higher level of  needs and force them to attempt to achieve self-esteem and  development by Ergonomy effects on  increasing efficiency has examined  in variety of organization  and it has proved its principles cause better function in any organization

Risk assessment is a method of quantifying and quantifying the risks and consequences of potential accidents on individuals, materials, equipment and the environment. By doing so, the effectiveness of existing control methods will be identified and valuable data will be provided to make risk reduction decisions. The purposes of wastewater treatment can be classified into three main groups: provision of health conditions for people's lives, environmental cleanliness, reuse of wastewater (treated wastewater). In the last two decades, the rate of wastewater use for agricultural irrigation has increased due to the scarcity of water resources for agriculture, ensuring that the health hazards and soil degradation in the use of wastewater for agricultural irrigation have been met by taking the necessary precautions and observing standards. Recommendations will be minimized and socio-cultural validity increased. This study assessed the risks that municipal sewage treatment plants can create. The purpose of this study is to evaluate the risks of treatment plants with up-to-date methods and techniques and to provide control strategies to manage these risks. The study first identified the risks posed by urban wastewater treatment plants by visiting and consulting environmental experts. Subsequently, risk analysis, any deviation or accident was identified using the preliminary risk analysis method. According to the PHA risk assessment results, 22 environmental risks were identified prior to corrective actions, of which 11 were high priority, 8 high priority, 2 medium priority and 1 low priority. In other words, 50% of the aspects are at very high risk level, which after 2 corrective actions becomes high risk, 13 moderate risk and 7 low priority risk. Finally, corrective actions can reduce the very high risks associated with corrective actions.

The growth in urbanization during the recent decades has increases healthcare, social, and economic inequalities at a large scale among the residents of many cities. One of the most important consequences of this trend is the tendency of citizens towards a sedentary lifestyle in Iran and around the world. Lack of physical activity, as one of the important issues in public health, is related to the living space and the daily activities of citizens and residents. Since there are no clear universal measures for measuring this phenomenon in urban space and environment, it is necessary to develop and propose a number of criteria for measuring the effects of physical activity on the quality of urban living space. In this regard, using criteria obtained from previous studies in the form of a theoretical framework, a measuring tool can be identified. Accordingly, the main objective of the current study is to develop a measuring tool for the quality of urban living space with an emphasis on the opportunities for physical activity and to evaluate the obtained measures in the area selected for the study, i.e. Hijab Neighborhood of Mashhad. The current study is a descriptive analytical one. Therefore, the theoretical concepts are gathered through library studies, and then, by developing a questionnaire, the obtained measuring tool is administered to the residents in Hijab Neighborhood. The obtained data were analyzed using SPSS software application. Based on the results, factor analysis shows that physical activity of citizens is influenced by four variables including the functional variable, availability variable, social variable, and aesthetic variable. Based on the results obtained from the analysis and the effect size of each of these variables on the variable of physical activity, it can be concluded that the functional factor has the highest level of impact on the quality of urban living space considering the opportunities provided for citizens to have physical activities. The availability factor, social factor, and the aesthetic factor are the other criteria affecting the level of citizens’ physical activity, respectively.

The mainpurposeofthisstudyistoprovideanoptimumpattern for evaluation and selection of construction industry contractors by HSE view. This research determines the main and secondary criteria which aected evaluating and selecting contractors by quantitative studies and special questionnaires and surveying perceptions. Sample size of 95% condence level and margin of error of 5 percent by 252 peoples, including 4 Group executives and managers, employers, contracting companies and experts in health, safety and the environment were determined by the employer and contractor. KMO and Bartlett's test and conrmatory functional analysis (CFA) were used as testing methods. Validity of this questionnaire was obtained as 0.863 by Cranach's Alpha coecientandreliabilityofquestionnairewasconrmed. This article tries to determine intensity of these criteria in patterns of a model. Results show that human resources criteria are with the most eectiveness and planning criteria are of little eect. Suggested pattern can fulll a continuous increase to a comprehensive pattern for evaluation and selection contractors. According to the proposed model, organizations can simply evaluate theircontractorsintermsofHSEperformance. Contractors can also use this model to assess and identify their own weaknesses in the eld of Health, Safety and Environment (HSE) of the model, which in turn "reduces accidents and improves awareness of contractors in the eld of HSE Management System, and so, Standards HSE will be the scope of its activities.

Nowadays, governments have focused on pedestrian walking as a mode of transportation due to its significant effect on improving health and traffic. System of walking development projects and facilities not only depend on other traffic modes but also need studies about pedestrian behaviors, actions and simulation of future traffic. Corresponding to the model developing for an advanced study in Tehran, pedestrian traffic has been simulated by Ptv.Viswalk software. The results of software is analyzed and compared with basic parameters, optimized parameters of Tehran and factors that advised by experts. Analysis of parameters sensitivity according to social resources model has been shown in this research. Results of simulation indicate that the outputs of the model are highly depends on a number of parameters that must be changed with high sensitivity.
