The purpose of this study was to analyse the relationship between ecological awareness and rice-field knowledge of paddy field women in Bandar- E Anzali and sustainable agriculture criteria observation extent. The research method used descriptive-analytic that is performed relative – causal method. The population included paddy field women, over 25 years old in two region. In this research, 275 women were selected with systematic sampling method. Instruments reliability was estimated by calculating Cronbach's alpha coefficient by SPSS/win. The descriptive findings showed that the research's paddy field women have good knowledge regarding ecological awareness and rice-field. Also, they are observing sustainability criteria in farming approximately. The analytic finding showed that there exists significant difference (%1) between the mean of observing sustainability criteria in farming, level of education, kind of ownership to field-rice and kind of used seed. Also, there exists positive significant correlation (p=%99) between age, past record paddy field, the measure of social participation, paddy field annual income, ecological awareness and paddy field knowledge and observing sustainability criteria in agriculture. But there exists negative significant correlation (p=%99) between the measure of paddy field participation and number of member household and observing sustainability criteria in farming. The measure of rice production and paddy field annual income as independent variable have maximum role and rate in analyzing of dependent variable.

Background and Objectives: Given that no comprehensive studies have yet been conducted on treatment of infectious wastes in hospitals of Qom City, this research was performed with the purpose of investigating the treatment methods used in these hospitals and monitoring the performance of waste elimination devices. Methods: Required information was obtained through in-person visit and observing the current situation, and the variables affecting waste treatment were extracted based on the type of treatment systems, and were collected, and accordingly, biological monitoring tests were designed for the studied hospitals. The data were analyzed using Fisher's exact test. Results: In this study, from 9 active hospitals in Qom Province, only 3 hospitals were equipped with waste treatment system. In hospital A, growth of Bacillus stearothermophilus spore were observed in 6.25% of the samples, while no microbial growth was recorded in hospital B. The initial investment to buy the machine in hospital A was about four times than that of hospital B. Conclusion: The findings of this study showed that treatment device of hospital B is more appropriate compared to the devices of hospital A due to complete destruction of spores, lower cost (for purchase), and maintenance. .
