The research is aimed to 1) study the level and priority of the factors affecting the delay of construction projects and 2) provide suggestions in relation to the prevention of such delay. The sample is 520 people who were working for different construction projects. They were project managers project engineers field engineers and foremen. The data were collected by using online questionnaires and analyzed to find out mean standard deviation (SD) frequency correlation coefficient and confirmatory factor analysis. The findings reveal two significant aspects. First those who were working in the construction projects concerned about the factors affecting the delay of the projects at high level. Respectively the factors related to design resource external factors and others were taken into consideration. The factor regarding to work performance is regarded affecting the project delay at the highest level. Other factors i.e. the design external factors and others and resource have the affects at the lower level. Second the work-related factors can help prevent the project delay. In other words the construction plan and methods as well as the project management should be well-implemented in accordance with the design. The construction site should be on inspection considering its drawing. Regarding the external factors and others the public voices of those living around the construction site should be taken into consideration. Furthermore the effective use of the resources can be carried out by sufficiently preparing all materials tools and equipment for constructing any project effectively as a consequence.

This research aims to study the level of fundamental factors in the composition of teamwork the training and team system performance factors of Thai go chess sports and the factors affecting the efficiency of teamwork of Thai go chess. It was a quantitative method doing a survey research. The sample group consisted of 286 members from the Thai go chess Association of Thailand. The research study tool was a questionnaire. The statistics used were frequency percentage mean standard deviation and Multiple Regression Analysis. The result of the study showed that 1) factors in the composition of teamwork are like team leader team member and teamwork were at the highest level. 2) Training factors including planning implementation and evaluation were very high and the issue at the highes level was the assessment of necessity. 3) The efficiency of the teamwork of Thai go chess highly depends on creativity and continuous improvement at the highest level and high-level issues are communication cooperation and coordination. 4) The essential factors in the composition of teamwork affecting efficiency teamwork of Thai go chess including team members and operating systems are at a statistically significant level of 0.01 5) Training factors that significantly affect the efficiency of teamwork of Thai go chess include assessment planning operation and evaluation at a statistically significant level of 0.01

The purposes of this research were 1) study the level of perceived usefulness perceived ease of use attitude towards social media and using social media of the elderly people in Bangkok 2) compare the use of social media for the elderly people classified by personal factors and 3) analyze the factors related to the use of social media for the elderly people in Bangkok. The quantitative approaches were applied by using questionnaire for data collection. The research samples were 320 elderly people in Bangkok. Descriptive and inference statistics were used; arithmetic mean standard deviation t-test One-Way ANOVA and Pearson correlation coefficient. The results were found that the results were found that the level of perceived usefulness perceived ease of use in social media were at a medium level (𝑥𝑥̅= 3.48 𝑥𝑥̅= 2.95). The elderlys attitude towards social media and using social media were at a high level (𝑥𝑥̅= 3.65 𝑥𝑥̅= 3.54). The hypothesis test revealed that: 1) the differences of age educational level and average monthly income affect the social media use of the elderly people differently was significant. 2) The perceived usefulness perceived ease of use and attitude towards social media were significant positively related to using social media of the elderly people in Bangkok.

This research suggests an add-on working compatibly with Google Forms to construct multiple-choice questions (MCQs). This add-on comprises two main components including software for constructing MCQs and a data storage for collecting data used to compose MCQs. I demonstrated effectiveness of the add-on by applying it in the context of repetition online learning in which students could learn relearn and take an exam of which MCQs generated by the add-on. At the last step of this research I suggest using a sentiment analysis method – based on natural language processing and machine learning to find environmental factors and teaching strategies suitable for the repetition online learning.
