Abstract
Background: The study on the influence of different protocol of resistance training on left ventricular of adolescent boys dose have its limitation. The aim of this study was to determine the influence of low-intensity resistance training versus high-intensity resistance training on left ventricular structure and function of healthy adolescent boys by echocardiography.
Materials and Methods: Twenty-four subjects volunteers, 15 to 18 years old were randomly assigned to three groups in the eight-member low-intensity resistance training (40% to 60% maximum strength), high-intensity resistance training (70% to 90% maximum strength) and control group. Protocol training was conducted 8 weeks, 3 sessions. Variables were measured using one and two-dimensional echocardiography at rest and special formulas.
Results: In the post-test to pre-test, in low-intensity resistance training group means values, left ventricular posterior wall thickness at end-systole (P=0.028) and resting heart rate (P=0.017) showed significant increase and decrease respectively. In post-test, it was shown a significant increase means values left ventricular posterior wall thickness at end-systole and left ventricular mass index in low-intensity resistance training group than high-intensity resistance training group (P=0.007 and P=0.005 respectively) and control group (P=0.005 and P=0.0015 respectively) and mean value left ventricular mass in low-intensity resistance training group than high-intensity resistance training group (P<0.007).
Conclusion: Low-intensity resistance training than high-intensity resistance training in healthy adolescent boys caused some changes in left ventricular structure and function, probably these changes were associated with increased volume and pressure load.

Abstract
Background: The climate change and particulate matter emission contented of bioaerosols is known as an important reason of increasing the allergic interactions especially in patients with defect in immunity system. The aim of this study was to investigate fungal bioaerosol concentrations in relation to particulate matter (PM10, PM2.5 and PM1) in indoor parts and ambient air of the generd educational hospital of Khorramabad city.
Materials and Methods: In this descriptive-analytical study, 192 samples (168 for indoor and 24 for outdoor) were gathered during 6 months at the seven indoor wards and one outdoor unit using Quick Take-30 method at an airflow rate of 28.3 L/min and sampling time of 2.5 min on to Sabouraud dextrose agar medium containing chloramphenicol. The sampling of particulate matter was carried out by Monitor Dust-Trak 8520. Also, the relative humidity and temperature were surveyed by TES-1360 digital.
Results: The results showed that infectious ward with 101.7 CFU/m3 was as the most contaminated part and operating room with 46.4 CFU/m3 was the cleanest part. Cladosporium with 36.75% and Rodotorolla with 1.3% had higher and lower of fungi rates, respectively. The rate of I/O<1 illustrate that this contamination had an outdoor source.
Conclusion: The surveys demonstrated that the increase of temperature and relative humidity have an effective influence on the pollutant accumulation. In addition, between fungi bioaerosols frequency and particulate matter ther was a significant correlation.

Abstract
Background: With regard to application of the oil fuel at winter in Dorud cement plant, the aim of this study was to investigaten NOX, SO2 and particulate matter (PM) dispersion from cement plant stack at downwind direction and atmospheric different conditions and thermal inversion in winter season up to distance 5000 m from emission source and its comparison with clean air and NAAQS standard.
Materials and Methods: In this study, the sampling gases exited from cement plant stack were carried out using Testo XL350 and particulates measurement done by Westech device. SCREEN3 software model was used to evaluate air quality and dispersion NOX, SO2 and PM. Data interred into the model includin emission rate, physical factor related with stack, height, length and width building, mixing height, meteorological stability and wind speed. This model incorporates sources related factors, meteorological factors and emission rates to estimate pollutant concentration from continuous sources. The class stability and wind speed were at a hight of 10 meter.
Results: The results showed that the maximum concentration predicted NOX, SO2 and PM by SCREEN3 in neutral condition (D) and wind speed 6 m/s was at 1084 m away from stack with concentration of 265.48µg/m3, 168.39µg/m3 and, 56.56µg/m3 for NOX, SO2 and PM respectively. Also, at stability condition (F) with wind speed 4 m/s the maximum concentration predicted in 2647 m away of stack with amount of 195.71µg/m3, 308.54µg/m3 and 65.37µg/m3 respectively.
Conclusion: In order to reach the clean air standard, continuous monitoring and development methods are necessary for control gases and particulates exited from stack.

Abstract
Background: The age pyramid of our country is being reversed. Planning for the provision of healthcare services for the elderly requires the investigation of the factors affecting their utilization of health services. The aim of this study was to determine the availability of hearth services for the elderly at Lorestan province and the relationship between their utilization of these services with socioeconomic variables.
Materials and Methods: This cross-sectional study was conducted in 2017. The study population included the elderly discharged from the hospitals affiliated to Lorestan University of Medical Sciences in 2017. The data of 428 patients were collected during phone interviews. The collected data were analysed by SPSS-18 software and chi-square test, Mann-Whitney test, Spearman test, and independent t-test.
Results: The rates of the utilization of medical and paramedical services in at least one occasion during the last three months among the studied elderly were 25.5% and 27.7%, respectivly. Utilization of health services was significantly affected by family structure, literacy status, residence of the patient (town or village), social origin (the residence until the age of 18), unemployment status, number of children, type of insurance, complementary insurance, having a chronic desease, self-evaluation of health status, satisfaction of the status quo, income, employment status, house ownership, and having a private room. However, there were not significant relationships between the elderly’s utilization of different health services and their gender, marital status, children’s location, and car ownership.
Conclusion: Elderly people utilize different health services more than the general population. Considering the significant relationship between certain socioeconomic variables and the utilization of health services among the elderly, it is recommended that planning for the provision of health services to them should be based on the investigation of their utilization of health services and their determinants.
