Use of radiological equipment in dentistry is vital for the diagnosis and treatment of oral and dental diseases. However, concerns about the leakage of radiation from these devices and its impact on public health are inevitable. The present study aimed to investigate the extent of radiation leakage in dental clinics in the city of Kashan, Iran, and its results can significantly contribute to the improvement of the safety of these environments.

This cross-sectional descriptive study was conducted in 30 randomly selected dental clinics. Data collection was performed using the Smart Ion Mini_Instruments Ltd (UK) for measuring radiation leakage, along with observations and inquiries to obtain demographic and protective information. The collected data were entered into the SPSS 24  and analyzed using statistical tests.

Based on the findings, 6 out of the 30 sampled clinics had radiation leakage values higher than the permissible limit, while 24 clinics were within the safe range. Moreover, in assessing the relationship between variables and radiation leakage, no significant correlation was found between radiation leakage and the demographic information of radiologists, such as gender, specialty, and work experience. Among protective measures, the presence of lead shielding showed the highest significant correlation with radiation leakage.

The study showed that 20% of the sampled offices had a high radiation leakage rate and that protective measures, especially the use of lead shields, were very important in reducing the radiation leakage rate in dental offices. The results indicated that the offices that used lead shields had less radiation leakage than other offices. Lack of a significant relationship between the demographic information of radiographers and the amount of radiation leakage indicated that this phenomenon is more related to technical factors and radiation equipment rather than personal factors, such as gender or expertise. These results revealed the necessity of emphasizing education and retraining and the implementation of safety standards and guidelines related to the use of radiology equipment in dental environments, as well as the necessity of periodic visits to dental offices.

Despite the availability of vaccines, the use of face masks remains a recognized and effective measure in preventing the spread of COVID-19. However, it is crucial to comprehend the underlying factors influencing people's adherence to preventive behaviors, particularly mask usage within communities, as negligence and disregard for this matter persist. Therefore, the present study aimed to identify the reasons for not using masks by people during the COVID-19 pandemic from the point of view of health experts.

This research employed a qualitative approach and content analysis in 2019. A targeted sampling method was employed, and 15 healthcare experts from Kashan and Aran and Bidgol, Iran, participated in this study. Participants were selected to represent maximum diversity in terms of age, gender, and education level. Semi-structured interviews were conducted as the primary method of data collection. The duration of the interviews varied between 20-30 min. The interview transcripts were carefully documented, extracted, and segmented into meaningful units. To enhance the research's reliability and confirm the accuracy of the findings, credibility criteria were employed to validate the collected data.

Out of the interview participants, 66.6% held a bachelor's degree, 13.4% possessed a master's degree, and 20% had a doctorate degree. Around 80% of the participants were male, with 53.5% falling within the 40-50 age range, and all were married. During the data analysis process, 40 core concepts sharing common characteristics were categorized into six subclasses, which were further condensed into three main classes based on abstract commonalities. The research findings were classified into three main categories: individual factors, interpersonal factors, and environmental factors. The subcategories included lack of awareness, behavioral and belief patterns, physical barriers, subjective norms, economic barriers, environmental barriers, inappropriate mask structure, and health policies and guidelines.

Based on the findings of this research, in addition to individual factors (e.g., awareness and beliefs regarding preventive behaviors), interpersonal factors, abstract norms, and economic and environmental factors can significantly influence mask usage within a society. This finding highlights the necessity of government organizations' support to address these challenges effectively.

One of the dangers that environmental health experts face at work is violence, the incidents of which are observed every year. The type and extent of this violence depend on the ethics of the operator. This s tudy aimed to determine the s tate of violence among environmental health experts in Kashan and Aran va Bidgol, Isfahan, Iran.

In this descriptive s tudy, 53 environmental health inspectors working in the centers affiliated with Kashan University of Medical Sciences, Kashan, Iran, were selected. The data collection tool was a 58-item reliability-validated ques tionnaire consis ting of four parts, including physical violence (18 items), psychological violence (12 items), sexual violence (12 items), and racial violence (12 items), and there were three open ques tions at the end of the ques tionnaire. After the ques tionnaire was completed, information was recorded in SPSS software, and analysis was performed using independent t, Chi-square, and Fisher s tatis tical tes ts.

According to the results, 30% of the subjects experienced a physical attack, 90% verbal violence, and 7% racial violence in the pas t three years. No cases of sexual violence were reported. Moreover, the curator's insult to the inspectors had no relationship with the inspectors' behavior and was influenced by factors related to the curator himself and cultural and social factors.

Based on the results, a combination of personnel training and improving their communication skills, as well as behavioral training for attendants, would be effective in reducing cases of violence.

Leishmaniasis, a common parasitic disease between humans and animals, which is currently one of the major health problems in many parts of Iran. Therefore, this study aimed to investigate the prevalence of cutaneous leishmaniasis in Aran and Bidgol and the effects of climatic factors on that during 2016-2019.

This cross-sectional study was performed by referring to the health records of 964 cutaneous leishmaniasis patients in Aran and Bidgol during 2016-2019 and epidemiological information was recorded. In addition, the climatic characteristics of the study area, including temperature, humidity, and precipitation were collected from the meteorological station of the study area. Then correlation analysis was performed between meteorological elements and the incidence of the disease. The data were analyzed using SPSS software version 16.

60% of the patients were male. The age group of 0-10 years had the highest frequency (23.9%) among patients. Also, 47.7% of the patients had a history of traveling to endemic areas and the highest rate of leishmaniasis was related to urban residents. There was also a weak positive correlation between humidity and rainfall with leishmaniasis incidence (r = +0.55).  A weak negative correlation was also observed between temperature of the environment and leishmaniasis incidence (r = -0.42).

Due to the significant increase in cutaneous leishmaniasis in recent years in the area, as well as the appropriate ecological conditions of the area for sand fly activity, it is recommended to conduct the necessary training to observe health in hot seasons and field controls, such as baiting.

Dissolving of clientschr('39') problems is one of the most important tasks of health centers and satisfaction of clients is an important indicator of quality assessment and evaluation. Therefore, considering to the importance of peoplechr('39')s satisfaction and their role in achieving the objectives of health promotion programs, this study was conducted with aim of  Satisfaction assessment of health centers of the community in Aran & Badgol City

This descriptive study was carried on 682 clients to all 20 health services comprehensive centers, health centers, and health houses under the Aran&Bidgol Health Center. A tool of collecting information was a questionnaire that evaluated relevant information in three areas of support, personnel and process. Data analysis was performed using SPSS software version 21 that Wilcoxon test were applied.

The statistical population of this study was 682 people, 553 (81.1%) were female and 129 (18.9%) were male. Based on the results of the study, the majority of patients (61.6%) were fully satisfied and only 8.8% 3% were dissatisfied. The results showed that the highest satisfaction was related to the field of personnel and the least satisfaction was related to the process area, in which 63.3% of the respondents were satisfied with the personnel, while 57.2% were in the field of development and 48.1% in the area. The process was completely satisfied. Based on the results of satisfaction of clients in comprehensive health centers, there were more than 20 thousand people significantly higher than the urban centers above 20 thousand people (p=0.00). Also, the satisfaction rate was significantly higher in those with a history of referral to health centers. You were higher (p = 0/02).

According to the results of this study, it is suggested that using strategy and proper planning, the level of satisfaction of the clients and their goodness from the centers of comprehensive health services should be maintained and in order to improve them, more fundamental measures are taken.

Introduction and The need to access and produce clean water is currently felt more than ever by the communities due to the pollution of drinking water sources and the consumers’ growing concern and awareness about the absence of healthy drinking water. As a result, in the recent years, the use of water purification systems has been widely increased in the urban and rural regions of Iran. Regarding this, the aim of the present study was to investigate the causes of the tendency to use home desalination systems in the households of Bandar Lengeh, Hormozgan, Iran.
This descriptive, cross-sectional study was conducted on 140 households in the fall of 2014. The study population was selected through simple random sampling technique. The data were collected using a questionnaire enquiring the cause of using home desalination systems among the people living in Bandar Lengeh. Data analysis was performed in SPSS, version 24 using Chi-square test.
According to the results of the present study, none of the investigated households directly used the water distributed in the city for drinking. Only 12.9% of the households used this water for cooking. Therefore, the water distributed in the urban network was mostly used for irrigation as well as washing dishes and clothes. Furthermore, the most frequently reported reasons for the non-use of the water were discoloration of tea and slowing down the cooking of food.
As the findings of the present study indicated, it is not essential to use the domestic purification systems. Accordingly, the tendency to use these systems are mainly raised by incorrect beliefs about this issue. This highlights the necessity of implementing educational programs targeting toward the improvement of the households’ awareness regarding the health issues.

In every time and place, accidents can cause damages or injuries to people, property, community and organization reputation. With respect to this point that accidents occurred in laboratories of our country, this study aimed to assess the hazards in laboratories and workshops of Isfahan University of Art and also the implementation of interventions to increase the safety level in these places.
This is a cross-sectional study. After initial evaluation of all workshops and laboratories of the Isfahan University of Art, 4 workshops and laboratories with high potential level of hazards were selected for further study. Then, for quantitative assessment of hazards made a 130-question assessment checklist was prepared based on OHSAS 18001. After performing quantitative assessment of hazards and prioritizing them based on the results of this evaluation, interventions were implemented to decrease hazards and increase the safety level. Finally, quantitative assessment repeated and efficacy of interventions has been identified.
Based on the quantitative assessment according to evaluation checklist score, the percentage of general hazards in target sites was 20.8 to 45.4 % (Mean = 35.5, SD=9.2). Lack of safety supplies, equipment and signs with 31% and deficiency of safety procedure with 26 % were the most important factors corresponding to evaluated safety risk levels. Two interventions were implemented, including designing and installing safety signs and safety training.
After the educational and safety interventions, total hazards decreased from range of (%20.8 - %45.4) to range of (%15.4 - %32.3). According to the low cost of the implementing the interventions, the mean overall safety level is decreased (10.6%) thus increasing the safety level is acceptable.

Background and Comprehensive evaluation of jobs in industries is a practical and effective method that could identify the jobs and industries with negative effects on the environment. This study identified environmental hazards of hot rolling process and assessing their risks.
An observational study was carried out in which identification of human activity and job´s risks in production hall of Kavir Steel Complex was done according to ISO 14001 approaches (pollutant emissions to air, discharges to water, energy consumption, energy released as heat, wastes, side products, etc) by Job Hazard Analysis method (JHA). Then the risks identified were prioritized and assessed using William Fine method.
We identified 205 environmental hazards (in 9 groups) associated with production personnel (n= 81), mechanics and maintenance personnel (n= 44), bed personnel (n= 9), personnel of cleaning services (n= 33), and water plant personnel (n= 38). The highest and lowest rate of risks were due to creation and distribution of wastes (n= 73) and corrosion and depreciation of equipment, (n= 1), respectively.
The production personnel were mainly responsible for environmental emissions. The leading causes were stress and anxiety about stoppage of production, payment reduction, and lack of awareness and workers and supervisors on environmental issues.

Requiring industries for implementing industrial waste management programs and planning for proper waste disposal is essential in order to achieve sustainable development. Therefore, industrial waste management program was done in Kavir Steel Complex, in Aran va Bidgol region to identify and classify industrial waste and also to present solutions for improving waste management. In this complex, production process is hot rolling steel and the product is rebar.
Material and The preset study was conducted in Kavir Steel Complex. Following survey of production process and sources of waste, the type and volume of produced waste were identified and measured during 3 months. Then, the classification of wastes was done according to the Bazel Convention and Resource Conservation and Recovery Act (RCRA), and finally new industrial & health solid waste management program was presented.
Considering the volume, industrial waste of production process in Kavir Steel Complex was between 130 to 180 grams per each ton of rebar. Main industrial waste included oxide of steel billet, industrial sludge, used oil and lubricant which were classified according to the RCRA: 8 materials with T code, 1 with C code, 5 with I code and 3 materials with C code.
The results revealed that the most amount of industrial waste in Kavir Steel Complex is the waste of steel billet and industrial sludge, and more than 90% of Kavir steel industrial waste were reused and recycled inside or outside of this complex. It is recommended that used oil to be transport and maintain in the safe containers.

In the absence of proper control, environmental hazards and risks from industries, can be irreparable damages to the environment. Hence, this study with the aim of environmental risks identification and assessment (such as emissions to air, discharges of pollutants into water, the discharge of pollutants in soil, consumption energy, etc) and estimation of control costs by (william fine) and (PHA) method in the Kavir steel Complex.
environmental hazards that identified by field observations, categoried on the Preliminary Hazard List (PHL) on unit, human activities and performance of the machines in the production hall of Kavir Steel; then was done risk assessment by William Fine method for calculation of (RAC1). After providing reform strategy for critical risks , (RAC2) calculated. In this study was used software (SPSS) version 19 for statistical calculations.
According to this study, the number of 356 environmental risk, in the form of 9-risk groups, identified. before the offered intervention strategies, the number of acceptable risks 89, the lowest practictable (ALARP) 204 and 63 was unacceptable risks. prospecting after the offered intervention strategies, changed the number of acceptable risks 183 and the lowest practicable (ALARP) 173.
The results show that the comprehensive identification and assessment of environmental risks in the rolling steel industry, presenting technical flaws and imperfections and errors of destructive environmental staff to the issue of environmental and making necessary to auditing environmental, and changing attitude of personnel, sensitivization of rolling steel industry personnel to maintain and improve the health of the environment.
