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.

The purpose of this research was to design and develop products from polyester yarn scraps according to an eco-economic design concept. The workpiece is formed by the compression molding machine used in the industrial system. Researchers studied the waste materials used in various processes of manufacturing in textile establishments to increase their value by designing a new product or by developing polyester yarn scraps. According to the research process with the upcycle method that focuses on using resources for maximum value by turning the scarps into new products and eco-design concepts to increase the value of plastic polymer waste one of the concepts of resource efficiency (4Rs) by recycling and design process. The research focuses on the process of polyester yarn scrap forming especially from the textile industry with the potential to be re formed to create new products with beautiful shapes and unique patterns. From polyester yarn scarps through the extrusion process. By using the compression molding machine with a compression force of 80 tons the temperature range and the time are controlled appropriately. Under the mold prototype hat from or flash mold.

An investigation into the development of souvenir product prototype from Hmong embroidered fabrics to improve seniors quality of life in Kalayaniwattana District Chiang Mai Province.The aim of this study was to 1) develop a souvenir product prototype made from Hmong ethnic embroidered fabrics in Kalayaniwattana District Chiang Mai Province. 2) To develop innovative manufacturing processes to increase skills for the seniors to minimize the embroidery time. 3) To study the satisfaction towards the prototype of souvenir products from Hmong embroidered fabrics in Kalayani Wattana District Chiang Mai Province by using a sample of 200 tourists. The data collection tool was satisfaction questionnaire on the development of a prototype of a souvenir product from Hmong ethnic embroidered fabrics to improve the seniors quality of life in Kalayaniwattana District Chiang Mai Province on the aspect of its utility beauty manufacturing process and 3 souvenir product prototypes namely type 1 childrens cloth type 2 ladies robes and type 3 bags by using a random questionnaire. The data analysis generated from percentage statistics arithmetic mean and standard deviation. The study results based on the research objectives revealed the outcome as followed.l) To develop a prototype of a souvenir product from Hmong ethnic embroidered fabrics from sample group of 25 people the study found that the draft design that was satisfied as a souvenir prototype was group 1 childrens cloth. The most satisfied model was draft design 1.2 (= 4.36) group 2 shirts. The most satisfied womens group was draft design 2.1 (= 4.28). As for group 3 the bag which was assessed with highest satisfaction was draft design 3.1 (= 4.40). 2) To develop innovations in manufacturing process to enhance skills for seniors to reduce the embroidery duration it revealed that the star pattern was the simplest embroidery pattern reflecting Hmong identity through embroidered fabrics by application of antique tones together with the method of mixed silk embroidery with embroidering patch into round pieces to reduce the process and to facilitate fast embroidery process. 3) To study the satisfaction towards the prototype of souvenir products from Hmong ethnic embroidered fabrics part 1 the results of the general data study of the respondents found that most of the respondents were female accounted for 63.5 percent aged between 26-30 years representing 33.5 percent most of them were married 56% most of them graduated with a bachelors degree accounted for 60 percent most of them were employed as general staff accounted for 31 percent with monthly income at 15001-20000 baht representing 35.5% most of them domiciled in other provinces accounted for 55.5%. Part 2 information about the behavior of purchasing souvenirs found that most of the respondents already knew Kalayani Vadhana District Chiang Mai Province from social media channels (Social Network) accounted for 89 percent most of them had bought and used Hmong embroidered products 81.5 percent most of respondents would recommend other people to visit again at 100 percent most of the respondents perceived the souvenir prototypes were interesting 99 percent. Part 3 the satisfaction towards design and development of souvenir products prototypes made from Hmong embroidered fabrics found that the souvenir product prototypes that received the most satisfaction were type 3 bags (x-= 4.56 S.D. = 0.59.) in total aspects received the highest level of satisfaction followed by type 1 childrens cloth (x- = 4.52 S.D. = 0.55) with the highest level of satisfaction in all aspects and type 2 womens cloth (x-). = 4.45 S.D. = 0.65). Globally all aspects were satisfied at a high level.

The objectives of this research were 1) to create a game-based teaching media for learning about food selection among junior high school students. 2) To compare the learning achievements of lecture- based teaching with game- based teaching. And 3) to study the satisfaction of junior high school students with game- based teaching materials for learning about food selection. The sample consisted of 34 students studying in Mathayom 2 at Nawaminthrachinuthit Suankularb Wittayalai Samutprakarn School academic year 2022. The samples were selected using Cluster Random Sampling method. The instruments used in the research were the media quality assessment and student satisfaction assessment. The statistics used to analyze the data were mean standard deviation and t-test. The results of the research were as follows: 1) the creation of game-based teachingmedia for learning about food selection found that the suitability of teaching materials as a whole was of a very good quality while the content aspect was also at a very goodlevel and in terms of educational technology the quality was very good in all aspects. 2) The comparison of middle school student learning achievement after using method of lecture-based and game-based for learning in terms of buying food selection.
