Abstract
Background: Due to the lack of a proper waste management system, Tehran Municipality Region 20 is facing economic and environmental problems such as the high costs of a disposal system and source pollution. Life cycle assessment (LCA) is a method for collecting and evaluating the inputs, outputs, and potential environmental impacts of a product system throughout its life cycle. The current study purposed to provide a stable and optimized system of solid waste management in Tehran Municipality Region 20.
Methods: The LCA method was used to evaluate various scenarios and compare the effects on environmental aspects of management systems. Four scenarios were defined based on existing and possible future waste management systems for this region. These scenarios were considered with different percentages for source separation, composting, recycling, and energy recovery.
Results: Based on the results of this study, Scenario 4 (source separation [14%] + composting [30%] + municipal recycling facility [MRF] [20%] + energy recovery [10%] + landfilling [26%]) was found to be the option with the minimum environmental impact. In the absence of government support and sufficient funds for establishing energy recovery facilities, the third scenario (source separation [14%] + composting [30%] +MRF [20%] + landfilling [36%]) is recommended.
Conclusion: The results acquired from this investigation will confirm the belief that LCA as an environmental device may be successfully used in an integrated solid waste management system (ISWMS) as a support tool for decision-making.

Abstract
Background: Hospital-acquired infection (HAI) or nosocomial infection is a major public health concern. In this study, the status of knowledge, attitude, and practice (KAP) of service staff and nurse aids in reference to HAI was investigated.
Methods: This descriptive-analytic study was carried out to investigate KAP in two steps design and measurement. Twenty-five hospitals were included in this study. To collect data, a questionnaire comprised of 8 divisions and 45 questions was designed and validated, and the three sections of KAP were listed. The questionnaire was distributed to 405 nurse aids and service staff to determine their level of KAP towards HAI. The data were analyzed using SPSS 18.
Results: The mean ± standard deviation values of KAP of the included staff were 7.07 ± 1.97, 23.08 ± 4.38, and 35.83 ± 8.25, respectively. A statistically significant difference was observed in the level of KAP of personnel among different hospitals (P < 0.001). The type of employment status and education was found to be significantly influential on knowledge (P = 0.027, P < 0.001) and level of education. Marital status, education and career experience were found to be significantly influential on attitude (P = 0.034, P = 0.004 and 0.045). Level of education, job category, career experience, and gender were the significant influential factors on practice (P < 0.05).
Conclusion: The knowledge and practice levels were low in many nurse aids and service staff. An educational plan and compiled programs in hospital infection control seem to be necessary to effectively control the major concern of HAI in hospitals in Iran.
