The study of the impact of work observation course on increasing the efficiency of training in Applied Science Center of Farsan

This experimental research was conducted in survey method which aimed to investigate the effect of work seeing course on increasing the efficiency of training in Farsan Applied Science Center. The research sample consists of 285 new admitted students at Applied Science Center of Farsan in 2012. Given that this project was implemented for the first time, all new students were selected as statistical population and required information was collected through the researcher-made questionnaire. Finally, the obtained data were analyzed through statistical methods. The results of this study confirmed that the mean impact of work observation course on familiarity with careers was related to the field of study, students' familiarity with actual environment of work and implementing process of work, students' familiarity with activities leading to the production or providing service, students' familiarity with desired career position, promotion of students' motivation to work in job related area and familiarity of students with competences needed to obtain desired job, but the mean of work observation course's impact on students' familiarity with subjects and issues of career and students' familiarity with the benefits and privileges of career and evolution creation is not higher than average

Evaluation of university performance using BSC and ANP

Measuring the relative performance of universities play important role on better educational planning. During the past few years, balanced scorecard (BSC) has become popular among researchers as a technique for measuring the performance of business units. This method studies a particular firm in terms of four different perspectives including internal processes, learning and growth, customer and financial figures. One primary concern on using such method is that this method does not consider the relative importance of these components. In this paper, we present a hybrid of BSC with analytical network process to measure the relative performance of an educational unit in Iran

Trends of particulate matter (PM10) concentration and related Air Quality Index (AQI) during 2005-2012 in Kermanshah, Iran

Background and Aims: Atmospheric dust, also known as a part of PM10, can cause some adverse effects on public health. The aim of this study was to investigate dust concentration trends in Kermanshah city and also to compare related Air Quality Index (AQI) in different years, seasons and months during 2005 to 2012.Materials and Methods: In this descriptive-analytical study, totally 2589 samples were taken from air monitoring stations owned by the Environmental Protection Agency. The ghatered data were then analyzed using SPSS software V.16.Results: The frequency percentage of PM10 concentrations based on AQI descriptions (healthy, moderate, unhealthy for sensitive groups, unhealthy, very unhealthy and dangerous) were 12.16, 68.36, 12.82, 3.43, 0.77 and 2.43 percents, respectively. It is further interesting to note that in all monitored days during the present study, 19.43% of total days were in unhealthy conditions within AQI> 100. So that, although the frequency of dusty days decreased from summer to fall, failure to meet air quality standard requirements increased from fall to winter and further to spring.Conclusion: The results of this study showed that the observed changes in PM10 concentration were significant in the course of seasons and months. The worst air quality condition occured in summer (specially July). It seems possible that these results are due to frequent dust enterance originating from neighboring countries, humidity reduction, drought and unsustainable use of water resources, temperature rising, as well as wind speed and direction. Because of adverse health effects of particulate matter, it is necessary to promote environmentally aware and responsible science of its trend, short-term and long-term and also international planning to reduce its detrimental impacts.Key words: Air pollution, AQI, Dust, Kermansha

Efficacy evaluation of drinking water distribution network existence in microbial quality desirability and its chlorination status in small communities - Case study: Kermanshah province villages

Background and Aims: Safe drinking water supply is very important for human societies. The goal of this study is the determination of drinking water distribution network existence in microbial quality desirability and its chlorination status in small communities – Case study: Kermanshah province villages.Material and Methods: This method of the study is descriptive and analytical. The required data and information were collected from existing data of health center. The collected samples for microbial quality monitoring of rural drinking water were taken by health center during three-year period, that were 9174 samples. Data analysis was taken by SPSS software by using T-Test and ANOVA.Results: The results showed 79.7% and 84.3% as an average rate of desirability of microbial water quality and residual chlorination status respectively in villages having distribution system and 60.36% and 69.56% in those without distribution system.Conclusion: Assessing of microbial quality of water in all rural areas showed that villages with distribution network have better quality than other villages. So development planning for implementation of water distribution networks are suggested in other rural communities also for improvment of water quality in all rural communities (with and without distribution networks) the water safety plane should be employed.Key words: Microbial quality, Residual chlorine, Rural area, Distribution network, Kermansha

Survey of pollutant emissions from stack of Saman cement factory of Kermanshah city from year 2011 to 2012

Background and Aims: Toxic gases and hazardous particulates that release into environment from cement factories have considered as the environmental problems. This study aimed to determine the level of air pollutants from the stacks and the ambient air of the Kermanshah Saman cement factory and its comparison with existing standards.Materials and Methods: This is a Descriptive - analytical study. The assessed parameters include the suspended particles CO, NO2, NO and SO2 from pre-heater, crusher, and electro filter have performed according to the method of Perkinz air pollution control.Results: Results showed that amount of suspended particulates was lower than the industry emissions standard, which has been approved as a national standard for crusher (200 mg per cubic meter) electro-filter (150 mg per cubic meter). However, the amount of gases emission was more than standard.Conclusions: This study revealed that the controlling devices have good ability in particles control. Although the exhaust gases seemingly different from the standard, but the difference is not significant.However further controls are recommended for control of gases pollutants.Key words: Cement factory, Particulate, Polluting gases, Kermanshah
