This research aimed to experimentally study of solar panel efficiency with water cooling. Three mono-crystalline solar panels with the capacity of 80 W (for each panel) were used for this test. The first panel was a solar panel without water cooling. The second panel was a panel with water spray cooling. The last panel was a solar panel with water drop cooling. The cooling water flow rate was varied to 50 75 and 100 LPH. From the test it was found that the temperatures of all solar panels had the similar trends. The solar panel efficiency decreased when the temperature of solar panel increases. The solar panel efficiency increased when the cooling water flow rate was increased for both of water spray cooling and water drop cooling. For all water cooling flow rates the water spray cooling solar panel performed higher efficiency than water drop cooling solar panel. The highest solar panel efficiency in this test occurred when the water spray cooling flow rate of 100 LPH.

The surveillance and reports on accidents for the current traffic management are carried out by viewing and inspecting CCTV footage. This method is slow to detect incidents and requires a lot of manpower. Since nowadays communication technology and social media play a role in reporting such incidents this research has been conducted to investigate accidents of interest from text messages reported on social media in Thai. There is currently no research or platform that supports this type of work clearly. This research presented the development of a neuron network memory-learning model to solve the problem of incidence pattern classification and incidence severity identification from social media messages in Thai. Using deep learning models such as MLP CNN Bi-LSTM and LSTM+CNN the study was designed and divided into three experimental patterns. This included examining patterns to identify traffic incidents that may be reported as general news or traffic reporting; examining patterns to indicate the type of incidents such as traffic accidents disasters damaged roads or others other than those mentioned; and examining patterns to specify the severity levels of the incidents such as normal intermediate traffic lane blocking or immovable. The experiments demonstrated the capability of CNN+LSTM learning models with the best incidence detection result at 93.44 %. The CNN model gave the best result in identifying a pattern of incidence at 85.29 % and the LSTM model was best able to determine the severity levels of the incidence at 88.53 %.

Community developer And 112 family leaders in the community at Ban Khon Kwang Community Muang District Prachinburi Province presented in the table image. Descriptive statistics were used for frequency and percentage (Percentage) and descriptive statistics were mean and standard deviation to describe the level of awareness. Presentation of analysis results Therefore the researcher defined the symbols used in the analysis as follows: x represents the arithmetic mean of the data obtained from the sample SD represents the standard deviation of the sample Sig. Represents the statistical significance t represents the difference test. Difference of mean F instead of analysis of variance * representing a statistically significant confidence 0.05 ** representing a statistically significant confidence 0.01 The research results were found that : 1) Most of the samples were female. Be under the age of 40 bachelors degree occupation. Agriculture income less than 15000 baht period of stay in the community for more than 10 years. 2) The level of perception of community development activities of the people in Ban Khon Kwang community Mueang District Prachinburi Province There was a level of knowledge of three aspects of the village development operation. Overall it was at the highest level with the mean of 4.62. All of the above are at the highest level. By acknowledging policy information Were the highest at the mean 4.66 followed by perceived 3) Activities guidelines And the awareness of planning information at an average of 4.60 And 4.59 respectively. Assumptions 1. Perceptions of employee community development operations consisted of policy planning and community development. And guidelines for conducting activities Affect their participation in community development operations accept 4) The factors promoting public participation consisted of training participation Activities and membership of the bog Affect their participation in community development operations accept

This study of the role of family locals and community in enhancing the quality of elderly people’s lives in central area by means of Sufficiency Economy theory collected the data from people. It aims 1) to study the role of family locals and the community to enhance the quality of elderly people’s life in Thailand’s central region; 2) to analyze factors related to the quality of elderly people’s lives; and 3) to identify ways of encouraging the development of elderly people to prepare them to be part of the society of elderly people in the ASEAN region. The participants in this research were elderly people in the central region. The research used quantitative methods to measure quality of life. Multi-stage sampling was employed. The data were analyzed with descriptive statistics such as average (x̅) and standard deviation to investigate the elements of each factor in the study. The results from the focus group regarding the quality of elderly people’s life can be summarized as follows: 1) The development of the quality of life of elderly people is based on the concept of “Strong community and people through the development and adaptation of the theory of the Sufficency Economy”. 2) The development of the quality of elderly people’s lives by means of religion: emphasizing the Buddhist way of life and local wisdom and culture to teach family members to be a grateful and loyal and to be a good person for the family and local community. 3) The quality of life of elderly people can be improved by implementing laws informed by morality to encourage generosity between family locals and community to solve the problems of elderly people. 4) The quality of life of elderly people locals and the community is based on mutual respect living together naturally according to the concept of the Sufficiency Economy in order to support large numbers of elderly people in the future. Suggestions arising from this research and from other ideas from participants include increases in government funds budgeted to support elderly people and the creation by local government of projects and activities for elderly people. In addition the participants also perceive the need for a chance for the elderly to study and learn in the local elderly school without age limit as a form of life-long learning. The participants also suggested the idea of evaluating the systems of schools for elderly people according to the “cheerfulness and happiness” of learners rather than by any other method. Connections between the schools for elderly learners in the central area should be co-ordinated so as to create more projects and activities.
