Abstract
Background and objectives: Nowadays, demand for bottled water consumption is growing in most countries especially in Iran. Over 100 different brands of bottled water are produced and distributed in Iran. In order to protect consumer health, the microbial and chemical quality monitoring of such water has great importance. This study aimed to survey the quality of 15 high consumed brands of bottled water in Iran. Methods: This research is a descriptive-analytical and cross- sectional study which carried out on 15 brands of bottled water during 2009-2010. As a whole 60 samples (1.5 liter) were purchased randomly from supermarkets during four seasons. Samples were analyzed to determine residual chlorine, microbial quality and heavy metal concentrations according to standard methods. Results: No total and fecal Coliform were found in all samples. Concentration of chromium, cadmium, lead, nickel, copper, zinc, and silver in all examined samples ranged from 0.24 to 2.77, 0.15 to 6.00, 0.37 to 10.4, 0.13 to 2.01, 0.24 to 3.21, 0.55 to 2.03, and 0.12 to 1.55 µgl-1, respectively. Conclusion: Microbial quality and heavy metal concentration in all studied brands were in compliance with Iranian and US EPA standards, and WHO guidelines, so there is no public health concerns regarding consumption of bottled water.

Abstract
Background and objective: Because of the health hazards associated with swimming pools, it is essential to monitor their water quality to insure safety of water and compliance with standards. This study aimed to survey water microbial quality of swimming pools in Gorgan during 2009 in terms of free chlorine residual and microbial indicators including Total Coliform, Fecal Coliform, Pseudomonas aeruginosa, and Fecal Streptococcus. Methods: In a cross-sectional study, a total number of 209 samples were collected from all swimming pools in 2009. The samples were shipped to a laboratory (maintaining cold chain) to determine microbial quality. In addition, on-site measurements of free chlorine levels were made using special Kits based on the DPD colorimetric method. Results: The Results showed that in 2009, chlorine levels in swimming pool waters in 25.84%, 74.16%, 67.94%, and 41.15% of samples, respectively, were 0, >0, >0.6 mg/l, and in an optimum range of.1-3 mg/l. 14.35%, 11.96%, 10.05%, and 8.13% of samples were contaminated to Total Coliform, Fecal Coliform, Pseudomonas aeruginosa, and Fecal Streptococcus, respectively. A significant relationship was found between microbial quality and free chlorine levels. Conclusion: Some levels of microbial contamination were observed in swimming pools. Almost all the contaminations were occurred in those samples with no free chlorine residual. The residual chlorine yielded significant improvement in water quality of swimming pools in Gorgan. Since free chlorine was equal to zero in ~ 25% of samples, attention should be paid to keep free chlorine levels in allowable ranges.

Abstract
Background & Objectives: National water and wastewater industry has defined its 20-years goals to provide wastewater collection and treatment systems for at least 60% of the urban population. This study illustrates the status of wastewater management, construction and development of wastewater collection and treatment facilities, and limitations in this field. Methods: Questionnaires were sent out to water and waste water companies of 1016 urban areas. The results provided in the paper were taken from those questionnaires. Results: The results show that two (i.e. absorption wells and sanitary sewers) and four methods (i.e. absorption wells, sanitary sewers, and discharge into public places with or without canals) are currently being used for human wastewater management, respectively. Currently, 18% of urban areas are partially covered by waste water collection networks in Iran that is considerably lower than those of other middle-income countries. With completion of waste water collection plans this will increase to 37%. Conclusion: current wastewater management causes problem for more than 50% of urban areas in 42.47 of cities and more than 50% of population in 52.42% of cities. The most important limitations on completion of wastewater collection planes are inappropriate texture of soil and narrowness of pedestrians, sideways, and streets.

Methods: The research design was a semi-experimental one with pretest-posttest and control group format. The sample included all in patients with type II diabetes who referred to Taleghani Diabetes Hospital in Kermanshah city in 2014-15 (N=490), who were assessed based on DSM_IV_TR criteria, DASS-21, WHOQOL-26, and coping styles. Those who got highest scores were selected. The study subjects, were randomly divided into experimental and control groups (n1=n2=8). The experimental group was exposed to 8 sessions of two hours ACT. The data was analyzed using descriptive statistics and multivariate analysis of covariance (MANCOVA) by SPSS-16 software.
Results: The results showed significant difference between experimental and control groups total scores in depression, anxiety, stress, coping styles (Problem Solving, Emotional, Avoidance), (p<0.05). Also, quality of life, psychological, social and environmental health components had significant difference, (p<0.05), but no difference was observed in physical health (p>0.05).
Conclusion: The results emphasize the importance of this intervention in psychosomatic and chronic diseases and provide new horizons in clinical interventions.

Abstract
Background & aim: Staying at Behvarz position in all the employment period, lack of job promotion, and need to reside in the village can increase burnout in this occupational group. The aim of this study was to determine relationships between job burnout and socioeconomic factors among Behvarzes in Golestan province.
Methods: All the 1141 Behvarzes participated in present cross sectional study. Data were collected by Maslach Burnout questionnaire for which the reliability and validity were already confirmed. Data were analyzed by Multinomial Logistic Regression test at a significance level of 0.05 using SPSS-16.
Results: There were significant correlations between intensity of job burnout and income dissatisfaction, job disaffection, number of children, age, years of services, the city where they working, and decrease in level of education. Frequency of job burnout significantly correlated with housing conditions, place of residence, the city where they working, job disaffection, income dissatisfaction, age, years of services, and decrease in level of education.
Conclusion: It is necessary to apply appropriate interventions on Behvarzes who dissatisfy from their job and income, have more children, have lower education, and are older and more experienced than others.

Abstract
Background & objectives: Road dust pollution containing trace elements like antimony (Sb), lanthanum (La), lithium (Li), molybdenum (Mo), and vanadium (V) has been relatively overlooked. Despite their toxicity and established reference doses, there has been limited research on these elements. This study aims to assess the levels of these elements in the road dust of southern Tehran, an area with high pollution potential, and evaluate the associated health risks.
Methods: In this cross-sectional descriptive study, road dust samples were collected from the surfaces of roads in southern Tehran during a dry period. The samples were digested with acid, and the concentrations of Sb, La, Li, Mo, and V were determined using ICP-OES. Enrichment factor (EF), pollution index (PI), and Nemerow Integrated Pollution Index (NIPI) were calculated based on the concentration data. Non-carcinogenic risk was assessed through Monte Carlo simulation.
Results: The average concentrations of Sb, La, Li, Mo, and V were 2.01, 14.68, 9.05, 7.33, and 58.28 μg/g, respectively. The highest and lowest EF values were recorded for Sb and Li, respectively. NIPI values ranged from 2.16 to 44.58. The non-carcinogenic risk values of Sb, Li, Mo, and V for both adult and child age groups, and La for adults, were below 1, except for the risk of La in children, which was deemed unacceptable.
Conclusion: The findings of this study highlight significant levels of toxic trace elements in road dust in southern Tehran, indicating high pollution levels. Moreover, the current levels of La may present an unacceptable non-carcinogenic risk to children. Hence, greater attention towards this type of pollution is imperative, necessitating identification and control of its sources.

Abstract
Background & objectives: Human resource productivity serves as a crucial metric for evaluating organizational effectiveness, particularly in the healthcare sector where the quality of service directly impacts community well-being. This study aims to assess the human resource productivity as perceived by healthcare employees in Gorgan City, utilizing the Achieve Model framework.
Methods: This descriptive cross-sectional study involved 313 employees from various sectors of the Golestan Province health department, including urban and rural health service centers in Gorgan City. A stratified random sampling technique was employed to ensure representation across different groups. Data collection was facilitated through a validated questionnaire based on the Achieve Model of human resource productivity. Statistical analyses were conducted using SPSS-23, employing both descriptive and inferential statistics to draw meaningful insights from the data.
Results: The analysis revealed an average productivity score of 79.81±15.09 among healthcare staff in Gorgan, indicating that overall productivity levels fell within an average range. Notably, the highest scores were attributed to the dimensions of ability, feedback, adaptability, understanding, and knowledge. Conversely, dimensions associated with organizational support and motivation scored the lowest, highlighting potential areas for improvement. Furthermore, significant relationships emerged between various demographic factors - such as education level (p=0.020), workplace setting (p<0.001), and occupational group (p=0.001) - with productivity in the ability dimension. Age (p=0.027) and work experience (p=0.007) also demonstrated significant correlations with the understanding and recognition dimension.
Conclusion: It is crucial to understand the factors that impact employee performance and productivity, considering their significant role in organizational productivity.
