Abstract
Background and Aim: By definition, the ratio of output to input in any firm is called efficiency. In general, there are two main approaches for measuring efficiency ─ parametric and non-parametric. The objective of this study was to assess the efficiency of Health Services Workshops in Iran in 2006.
Methods and Materials: The efficiency of Health Services Workshops in Iran in 2006 was assessed using the non-parametric method, based on linear programming. More specifically, the Data Envelopment Analysis (D.E.A) was used. The most important feature of the Data Envelopment Analysis (D.E.A) is its applicability for the firms that operate under a multiple input-and-output framework. Assessment of efficiency was based on 2 assumptions, namely, fixed and variable efficiency.
Results: The data show that, based on fixed efficiency, the efficiency in the Bushehr, Fars, Kerman, Mazandaran and Yazd provinces is the highest, the average being 80%, which means that the idle capacity is 20% . Based on the variable efficiency. assumption, in Ilam, Chahar Mahal-and-Bakhtiari, Semnan, and Kohgiluyeh Boyerahmad provinces the efficiency is 85% (idle capacity = 20%).
Conclusion: On the whole, the Chaharmahal-Bakhtiyari province is the most efficient in holding Health Services Workshops in Iran. Therefore, other provinces should follow this province as an example when planning to increase their efficiency.

Abstract
Background and Aim: Weight status perception is an important factor in nutritional behavior. The aim of this study was to determine Islamshahr women's self-perception of their obesity status and perception of their husbands' opinions regarding women's obesity status, as compared with the actual central obesity status of the women.
Materials and Methods: This was a cross-sectional (descriptive-analytical) study carried out in 2003 on a cluster sample of Islamshahr women aged 20-65 years (n = 704). Data were collected by interviews and weight, height, and waist and hip circumferences were measured. A waist-to-hip ratio (WHR) greater than 0.849 was considered as central obesity. Based on the body mass index [BMI=weight/height2(kg/m2)], underweight, normal, overweight, and obese were defined as a BMI <18.5, 18.5-24.9 , 25-29.9, and ≥30, respectively.
Results: About 35% of the women with central obesity considered themselves underweight or normal. Married women's perception of husbands' opinions regarding their obesity status showed about 45% misclassification. Women with central obesity who thought their husbands would assess them as underweight or normal were more likely [OR=18.6, 95% CI: 9.1 to 38.2] to underestimate their obesity status as well.
Conclusion: Misperception of obesity status is common among Islamshahr women. Considering the role of central obesity in metabolic diseases, menstrual disorders and increasing serum androgens, conducting nutrition education programs is essential for prevention and control of central obesity in the region studied.

Abstract
Background and Aim : It is impossible to deny the threats and risks endangering the process of health care when offering the services. Confirming this fact does not mean ignorance the risk, or allowance to medical and nursing mistakes to happen however, it can mean approaching the problem to come up with practical solutions and minimize the risks in the process of providing health care services. The present study was conducted periodically as an applied multi-stage research.
Materials and Methods : To do a model of clinical risk management, different authentic texts on risk management in health sector were reviewed focusing on the models available. All such models were tabulated, analyzed and compared together which resulted 62 primary variables. The variables were, then, validated being used in a questionnaire responded by 20 nurses and doctors which, this time, produced a confirmed questionnaire of 40 variables. After that, 215 subjects chosen through a random and a stratified sampling were asked to respond to that questionnaire, making an exploratory factor analysis as well.
Results : This study was done, using principal components analysis as with a rotation of Varimax loadings showed a variety of factors (19 factors) available in the models of clinical risk management were loaded as "organizing and policy-making" factor. This factor illuminated a sum of 25.3% of variances in the model of clinical risk management. The results also showed the loading factor of variables as among 0.5 and 0.7 which indicated a fine correlation among them and the participants' view.
Conclusion: It was concluded that "the best care of the patient is accepted as a common perspective in organization" and "the effect of the treatment team's clinical performance on their financial payments" are the most and the least important variables respectively with 0.739 and 0.548 as factor load.

Abstract
Background and Aim: Congenital hypothyroidism is the most common metabolic disease and endocrine disorder in children and a major cause of mental retardation, which can be prevented only through early diagnosis and treatment. This study aimed to determine the prevalence of congenital hypothyroidism in newborns referred to Shahid-Ghodsi Health Center in Mashhad, Iran.
Materials and Methods: This cross-sectional study, including 4484 newborns referred to Shahid-Ghodsi Health Center for congenital hypothyroidism screening, was conducted during the first six months of 2015. Data were collected from the screening forms and analyzed using the statistical software SPSS 21, the tests being the two-sample T-test, analysis of variance, Chi-square and Fisher's exact tests; in all the tests the significance level was 5%.
Results: Of the 4484 neonates screened, 51% and 48% were males and females, respectively. The recall rate was estimated to be 2.6% and prevalence of the disease 1 in 370 neonates. There were statistically significant associations between hypothyroidism on the one hand and birthweight, type of feeding (nutrition), primary and serum TSH levels of the neonate on the other.
Conclusion: Based on the findings, the prevalence of congenital hypothyroidism in Mashhad is significantly higher than that national and global averages. It is essential to conduct more comprehensive research to determine the associated factors and design suitable interventions in order to prevent the disease.

Abstract
Background and Aim: High concentrations of particulate matter-25 (PM2.5) have been the cause of the unhealthiest days in Tehran, Iran in recent years. This study was conducted with the aim of the spatio-temporal analysis of traffic volume and its relationship with PM2.5 pollutant concentrations in Tehran metropolis, Tehran during 2015-2018, using the Geographic Information System (GIS).
Materials and Methods: In this study in different regions of Tehran, the Inverse Distance Weighting (IDW) model was used for prediction and zoning of the PM2.5 concentrations and traffic volume during the period 2015-2018. In addition, the association between the PM2.5 concentrations and traffic volume was determined based on the Geographically Weighted Regression (GWR) model.
Results: The findings showed that the southern and southwestern regions of Tehran had the highest PM2.5 pollutant concentration (annual average more than 40 μg/m3), while the eastern and northern regions had the highest traffic volume. In addition, based on the GWR model, the eastern regions were found to have the highest local R2 values (between 0.36 and 0.70).
Conclusion: In most regions of Tehran, no strong association can be found between high concentrations of PM2.5 and traffic volume. However, based on the findings of this study we cannot reject the relationship between traffic volume and PM2.5 pollutant but postulate other sources to be the main reason for the high concentrations of PM2.5. Thus, in the first step, these sources should be identified, followed by adopting strategies for traffic volume control and reduction aiming at having a cleaner air in Tehran.

Abstract
Background and Aim: Climate change on the earth is changing faster than ever before in the history. Cities are highly vulnerable to this climate change. Therefore, the present study aimed to investigate climate change in the metropolis of Tehran during the period 1991-2020 and help understand the limitations that cities may have in confronting climate change.
Materials and Methods: This descriptive-analytical study was performed based on the information obtained from the synoptic stations in the Tehran metropolis. First the relevant indicators were determined based on the opinions of experts and the existing literature, followed by analyzing the descriptive and analytical data on climate using the EXCEL-2016 software. Finally, based on reviewing the studies in the literature and analysis of climate data in the metropolis of Tehran, a single protocol was arrived at to study climate change in the city (microclimate) and how to reduce, and adapt with, the impacts of climate change in cities.
Results: Analysis of the data showed that the metropolis of Tehran had been facing an increase in temperature and a decrease in humidity over the preceding 30 years. The average monthly temperature increase and humidity decrease had been about 1.5° C and nearly 15%, respectively.
Conclusion: Tehran metropolis is faced with an increase in temperature and a decrease in humidity levels, the intensity of both of which will further increase in the future. Dense urban population areas will experience more intense climate change due to the formation of heat islands. To deal with this problem urban planners must consider urban socio-economic development in the context of adapting to climate change and reducing its impacts in various urban areas.

Abstract
Background and Aim: Cement production is the source of 7% of global CO2 emissions. In order to reduce emissions by 0.7% annually until 2030, the cement industries can adopt the circular economy model. The present study aimed to assess the environmental sustainability of the Sufian cement industry based on the circular economy model.
Materials and Methods: Based on the circular economy model of the Ellen MacArthur Foundation, this research was conducted in three steps in the Sufian Cement Factory in 2021-22: Step1. Data were collected on fuel consumption, electricity, water, production waste, released gases and costs; Step 2. Based on literature review and experts opinions strategies and solutions to move towards a circular economy were determined; Step 3. The index of linearity and rotation in the current and future state was calculated for the Sufian cement industry.
Results: The data obtained showed that the Sufian cement industry is currently heavily dependent on primary raw materials and operates in a linear economy. Implementing the recommended strategies would be expected to reduce the linearity index to below 1 and increase the rotation index to above 0.1. These findings indicate a positive shift towards a circular economy.
Conclusion: The findings of this study reveal that the Sufian cement industry is currently totally based on linear economy, but it can, through implementing the relevant strategies, potentially transit to a circular economy, which will increase the factory’s net profit, protect resources and reduce CO2 emissions.
