This study investigated municipal solid waste generation rate and its compositionincluding the level of knowledge, attitude and practice on municipal solid waste (MSW) management of highland rural tourist area in Chiang Rai Province, Mae Salong Nok Sub-district, Thailand in order to propose the guidelines for effective MSW in rural tourist areas. Samples of MSW were collected during weekdays and several weekends, and separated into 4 categories: general,recyclable, organic and hazardous waste. About 40 % of the MSW consisted of organic waste; plastic bags were widely present, comprising more than 60 % of the mass of the general waste group. Level of knowledge, attitude and practice(KAP) on MSW was evaluated using questionnaires. While respondents scored 80 % and 76 %, respectively, on their level of knowledge of, and attitude to MSW, practice fell far short at only 37 %. The results led to a recommendation to strengthen waste separation at source, implement waste reduction and recycling concepts to reduce the volume of plastic bags, and introduce composting of food waste. The study also highlights economic and financial benefits of waste recycling. Additional value-added could be derived from the organic waste recycling program by promoting production of bioextracts and compost at household level, in order to reduce the amount of organic wastes and carbon emissions. The general and recyclable wastes could also be converted to energy as refuse-derived fuel 2 (RDF-2); the estimated average heating value of this RDF-2 was 23.56 MJ kg-1. To sustain MSW management in tourist areas, environmental education and environmental awareness campaigns are needed, using the appropriate local languages for communication, and introduction of a fairer system based on the polluter-pays principle for the business sector.

Constant Deterioration

In the conditions of constant deterioration of the environment, municipal solid waste management (MSW) in Ukraine remains one of the most pressing challenges in environmental safety because of its significant accumulation in landfills and the lack of effective mechanisms for its disposal. Approximately 40- 50% of municipal solid waste is organic, so the removal of this part of waste from landfills through composting and conversion of waste into secondary material resources will significantly reduce the environmental load on existing and potentially planned landfills. Therefore, the choice of promising technologies for the disposal of organic waste is one of the major tasks to ensure environmental safety. One of the effective strategies for dealing with excessive amounts of organic waste and one of the best and most affordable technologies for the waste recycling system is composting.

Background and aim: Data available in the Kingdom of Saudi Arabia (KSA) about public knowledge, attitude, and practice (KAP) toward viral hepatitis infection are scarce. Such information is essential for designing effective intervention strategies for the prevention and control of viral hepatitis. This study aimed to assess the knowledge, attitude, and practice among residents of KSA toward hepatitis viruses. Methods: A cross-sectional descriptive study was conducted among 549 participants in Saudi Arabia. An electronic questionnaire (in Arabic) was used to measure the KAP of the participants. Data were analyzed using SPSS version 23 at significance level of .05. Results: Most of the 549 participants were Saudi citizens (96%; n = 527) and 26.6% (n = 146) of them were males and mostly from the western Saudi Arabia (72.9%; n = 400). Most participants did not hear about hepatitis viruses and showed low level of knowledge on viral hepatitis (42%). On the other hand, a positive attitude was apparent from participants’ responses, and their practices were toward protecting their bodies from the infection. Conclusion: The level of knowledge about viral hepatitis was low (42%) among KSA residents, and the practice and attitude of the participants were toward avoiding the infection. Awareness campaigns are required to increase the public knowledge about viral hepatitis.

COVID-19 pandemic results in unprecendeted impacts globally. New discoveries and knowledge on this pandemic is evolving. A study was conducted to determine factors that are associated with knowledge, attitude and practice among medical students at one of the public universities in Malaysia towards COVID-19 pandemic. A cross-sectional study was conducted through online surveys by using a set of questionnare. The questionnaire was adapted and adopted from validated sources. It was found that, the scores for knowledge, practice and attitude were high among medical students. Male students had higher level of knowledge whereas females had significantly higher level of attitude and practice. Level of knowledge differed between years of study. Clinical year students had higher level of knowledge and practice compared to pre-clinical year students. Findings from this study might prove as the baseline for planning awareness campaigns for students for better containment of COVID-19 and its further spread

Programming Techniques

Municipal solid waste (MSW) management presents an important challenge for all countries. In order to exploit them as a source of energy, a knowledge of their calorific value is essential. In fact, it can be experimentally measured by an oxygen bomb calorimeter. This process is, however, expensive. In this light, the purpose of this paper was to develop empirical models for the prediction of MSW higher heating value (HHV) from ultimate analysis. Two methods were used: multiple regression analysis and genetic programming formalism. Both techniques gave good results. Genetic programming, however, provides more accuracy compared to published works in terms of a great correlation coefficient (CC) and a low root mean square error (RMSE).
