The aim of this research was to study environmental catastrophes caused by climate change in northern Thailand, which have had a direct impact on people’s health, their quality of life, and the economy. It was found that the smog caused by forest fires, open-air burning, and smog emissions from vehicles has been the problems in northern Thailand. Furthermore, the level of particulate matter smaller than 10 microns (PM10) could rise to 383 micrograms per cubic meter of air in some years. This level exceeded by three times the air quality standards of Thailand with a 24-hour average level of 120 micrograms per cubic meter of air. Therefore, the purpose of this research was to study and develop the instruments, methods, and implementations in reducing the effects of climate change by constructing perception and collaboration in decreasing the effects of climate change through STEM Education with undergraduate students. The participants of this study were 67 students majoring in Industrial and Technological Education at Chiang Mai Rajabhat University who had the pre-service student teaching practicum experience in the academic year 2018. The participants of this study could be role models for knowledge management and publicize the knowledge of reducing catastrophic effects of smog among primary and secondary school students, school staff and communities and give aid when an emergency occurred. There were 40 schools in northern Thailand participating in this research project. With reference to the research findings, they revealed that before participating in this research project, the 67 students had knowledge of catastrophes caused by climate change in northern Thailand at a level of 45 percent on average, while their knowledge increased to 88 percent after taking part in this project. In other words, their knowledge increased by 43 percent or there was a significant increase in knowledge to 95 percent. It can be concluded that the students in this study could create a role model of knowledge management, distribute information on how to decrease catastrophe from the smog, and give help efficiently to the 40 schools participating in this research project when there was an emergency (without significant difference).
Training and practice on synthetic anatomical bone before perform real medical operation is useful for medical student and recently become part of medical procedure. Since there are various factors to considered, the attempt to imitate anatomical bone from medical image data of patient, using technology that based on Fused Deposition Modelling (FDM) is alternatively developed. Since durability and qualities of 3D printed model depend on process parameters which referred to 3D printer setting, this study aims to investigate effect of essential 3D printer setting parameters involve with mechanical properties of 3D printed anatomical bone part, focused on infill density and layer height, and determine regression model for mechanical strength prediction from selected printing parameters by using experimental design and statistical analysis that based on Design of Experiments (DOE). 2-levelled full factorial experiment was designed, 3 factors including layer height, infill density, and print speed were taken into account. After that, selected 27 Mid-section of femur bone from 3D medical image data were fabricated from filament of Poly-lactic acid (PLA). The models were underwent a three-point bending testing to investigate mechanical properties and statistical analyse to investigate the relationship of parameters.
The haze problem and particulate matter less than 2.5 microns (PM2.5) in Northern Thailand caused by climate change is directly impacted and indirectly impacted people. In the area is affected by the haze problem and particulate matter (PM2.5) the climate change is health effects of population, As reported by “Air Quality and Pollution City Ranking” on 12 March 2019 The world air-quality index in Chiang Mai province, as the ‘Rose of the North’ hit top of the scale as the worst polluted city in the world. The air quality index (AQI) hitting a staggering 271 with a diameter of fewer than 2.5 micrometers ranges from 170 micrograms per cubic meter (µg/m³) exceeding the safety standard of 50 µg/m³ or lower. The pollution is nasty in Chiang Mai, North Thailand, therefore it is necessary to create understanding and awareness of the haze problem and particulate matter in Chiang Mai province. This research is conducted by focusing on Mathayomsuksa 1 students include 40 people who are a group of students of Yupparaj Wittayalai School, Chiang Mai province, Thailand by exploring the understanding Organize activities to create awareness and participation in reducing the impact of the haze problem and particulate matter through the system “STEM EDUCATION”. The results of the activity evaluation made it known that students know the effects of haze problem and particulate matter with an average of 4.46 standard deviations equal to 0.59. As for the awareness and participation in reducing the impact of the haze problem and particulate matter through the STEM EDUCATION system, the average value is 3.5, the standard deviation is 0.72. In the overall picture, the mean is 4.18. The standard is 0.65. The level of satisfaction towards training on raising awareness of the haze problem and particulate matter is at a high level. Referring to my previous information, the researcher will develop tools and applications to create awareness and participation in reducing the impact of the haze problem and participate in matter for students in other schools.
Chiang Mai air pollution has persisted in crisis for more than a decade. This issue continues to exist owing to the government has failed in addressing related policies and/or explicit solutions to cope with adopting carrier of farmers. This research found that farmers are familiar with cattle raising because this has been an important part of the country since ancient times. Therefore, cattle production is not only safe economically but also sound indigenously and ecologically. This research was conducted in Mae Chaem District’s Ban Thab Sub-districts of Chiang Mai, where slash and burn corn has been dominant for maize plantation. Participatory Action Research (PAR) was implemented throughout interviewing and observing to collect data from 14 farmers in the selected area. Then the data was analyzed by the inductive approach and descriptive statistics to identify essential components for the sustainability of cattle production. Results yield by the participants indicate that cattle production is the potential to replace slash and burn for monoculture due to its advantages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
