การศึกษากลไกการเคลื่อนตัวของทองในระดับอะตอม ในการเปลี่ยนโครงสร้างทางพื้นผิวของฟิล์มทองที่ผลิตจากทองคำเปลว
The attempt to fabricate gold films on glass slide (Au/glass) and silicon wafer (Au/Si) with gold leaf was unsuccessful due to poor adhesion between the gold leaf and substrates. Alternatively Au/glass and Au/Si films were fabricated by placing the substrate into the free space within sputtering chamber to collect the access Au vapor during the typical sputtering process for other samples. In this study the physical changes were observed in both Au/glass and Au/Si film under the film annealing from 300⁰C-700⁰C. The visual inspection via cell phone camera the micrograph via Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) revealed the morphological changes with respect the annealing temperature in Au films due to solid state dewetting mechanism. The changes were more pronounce in Au/glass films than Au/Si films at the same annealing temperature. The X-ray diffraction measurement three phases of Au including Au(111) Au(200) and Au(220) in Au/glass films and one phase of Au(111) in Au/silicon films. The concentration and single crystallinity of Au(111) were increased with respect to annealing temperature in Au/glass film. For Au/Si films the concentration and single crystallinity of Au(111) were decreased at 300⁰C and then were increased at 700⁰C respectively. The physical changes of Au films are likely due to the movement of Au atoms via solid state dewetting and recrystallization. The heat intake from annealing process is likely induced the dewetting process by increasing the kinetic energy of Au atoms. While the recrystallization process is likely occur during the cooling period of the samples. Finally another factor that can affects the physical changes of Au films is the interface interaction between Au films and substrates.

This research is a qualitative research. Considering the situation of the elderly in Thailand B.E. 2016 and the study of the context of the community with a tendency to increase the proportion of the elderly population together with the problems and obstacles that there are still needs to participate in recreational activities. In this regard there were 38 key informants chosen by a purposive sampling method for each target group. The selected informants consisted of 30 elderly people between 60-69 years old 2 neighbors 2 community leaders 2 family members and 2 government officials. Due to the outbreak situation of COVID-19 the target group has to be adjusted accordingly. There were only 10 elderly people who were willing to be interviewed by phone. These informants are those who resides in Nang Loeng community Phra Nakhon District and Pom Prap Sattru Phai District Bangkok. The data was therefore collected by telephone interviews. It was found that the elderly’s highest average needs for recreational activities were the top 3 categories accordingly as follows: 1.the category of games sports and play 2. dance and 3. singing and music. The results of the research also showed a clear nature of the activities; that is these three types of recreational activities involved body movement fun activities and those that demonstrated their abilities and skills. It can be seen that these three types of recreational activities involved physical movement as the main component of exercise and dancing as well as gestures and posture while singing or playing music. This helps promote physical health mental health and a good quality of life for the elderly. The result also showed that the activities that the elderly most frequently participated in during the recent period were games sports and plays followed by singing and music and dance. The problems found from participating in recreational activities among the elderly was the insufficiency of equipment and facilities followed by the problem of inappropriate places for participating in recreational activities and the problem of inappropriate activity period. (too little or too much time).
