This research aimed to study the causes of changes in water quality and compare the water quality in Khlong Bang Khen Mai when the seasons and sampling points are different. These factors may cause a change in water quality. A total 50 of water samples were collected from 5 sampling points each point approximately 300 meters apart for a total distance of 1.5 kilometers. They cover three seasons such as winter (October 2020 to February 2021) summer (March to May 2021) and rainy (June and July 2021). Three parameters of this research which consist of both the chemical and physical quality parameters are pH Dissolved Oxygen (DO) and Electrical Conductivity (EC). The result shows that the average pH has ranged from 7.10 - 7.74 the dissolved oxygen (DO) was in 1.80 - 2.84 mg/L and the electrical conductivity (EC) was in the range of 327 - 517 μs/cm. A two-way analysis of variance is a statistical method used to compare the water quality in Khlong Bang Khen Mai. The results indicate that the test differences between seasons affected the change in water quality in all parameters with a statistically significant level of 0.05. Afterward the comparison of multiple comparisons by Scheffes method showed that the pH and dissolved oxygen (DO) in the rainy season were significantly different from winter and summer at the level of 0.05. For the electrical conductivity (EC) there was significant differences between summer and winter at the 0.05 level.

This research aims to study the demographic characteristics affecting the decision-making of the working-age group in Ratchathewi District Bangkok Thailand to buy clean food and examine the marketing mix influencing their decision-making. The study population comprised 68635 people aged between 21 and 59 years in the group mentioned above. The sample consisted of 397 people. Descriptive statistics frequency percentage mean and standard deviation (SD) and inferential statistics i.e. independent samples t-test one-way ANOVA Pearson correlation coefficient analysis and multiple regression analysis were used to analyze the collected data. The research results illustrated that demographic factors like the different ages and educational backgrounds caused differences in the decision-making to buy clean food at a statistically significant level of 0.05. Moreover the marketing mix involving product price and promotion positively impacted the overall decision-making to buy clean food. It also positively affected the decision process of the need arousal or problem recognition (ND) information search (IS) evaluation of alternatives (EA) purchasing decision (PD) and post-purchase behavior (PB). Furthermore the place positively impacted the overall decision-making only in the PB process. Since the product price and promotion affected each aspect of the decisionmaking process (ND IS EA PD and PB) it was recommended that the clean food shops should pay more attention to these aspects

Teaching and learning in the 21st century is not as focused on lecture notes as in the past. Students must listen to the teacher and answer exactly as the teacher teaches but emphasizes as the instructor is a coach or a facilitator is not a teacher that teaches only and must be organized Learning for change (Transformative Learning) is learning to make changes within oneself including worldview affective attributes cognitive attributes and behaviors (psychomotor attributes) is to change dramatically complete in all aspects it is a change known as the Holistic Change” (Thitirat Raksasri 2019). Learning with digital technology is considered a learning style suitable for the new generation. Because it is a model that can use technology to be useful in teaching and learning both inside and outside the classroom. Result in new learning styles such as massive open online courses (MOOCs) or other learning channels such as video computer games social media and audio media (OKMD 2019). It is therefore a good opportunity for students to be able to choose a learning style that is suitable for themselves. According to a study by Jiratan Prayaruwong (2019). It was found that learning English using digital media technology allows learners to develop and develop proficiency in English. It can be used to study and search for knowledge and information by oneself in the 21st century and achieve complete and effective lifelong learning skills. Therefore teaching and learning English integrated with digital technology and practical training it is a suitable idea for the development of English communication skills of Thai youth in the 21st century and in line with the education reform policy the national strategy for the development and enhancement of human resource capacity of Thailand at present (Nattaphon Teepsuwan 2019).

The objectives of this research seek to desired factors for established of model on innovative development of logistics management 5.0 to increased competitiveness of local herb product and local economic development. Theoretically the future research method using Delphi Technique approached to consensus from is purposive key informants. Who were relevance experts involving three rounds of in-depth interviews and questionnaire and the descriptive statistics included median and interquartile range (IR) were used to analyses Delphi consensus. The research findings indicated that demand chain factors consisted of 1) innovative development of customer engagement 2) innovative development of customer services 3) innovative development of customer responses and 4) innovative of manufacturing flow management. It combined with supply chain factors consisted of 1) innovative development of adaption 2) innovative development of value engineering 3) innovative development of value chain for logistics management and 4) innovative development of strategic alliance. Ultimately this above research results can be using to established model of innovative development of logistics 5.0 management to increase competitiveness of local herb products and grassroot economics development. (husband/wife/children) after retirement most of them do not have credit cards is the same sample group that has the highest level of planning for life after retirement. However the researcher tested the hypothesis and found that the majority of people are aware of the rise of an aging society and has increased investments before retirement age.

Moreover the educational level of the sample population is related to financial education and investment to prepare for retirement. Lastly the researcher found that working age people still need a lot of support for knowledge about sustainable retirement life management.
