The growth of the sandal market in Thailand is on the decline, with purchase behavior changing among young consumers. As a result, the factors of sandal design are currently changing as well. The objective of this research was to study the factors of sandal design using a quantitative method. The data were collected from 400 Gen-Z consumers aged between 18-27 years old in Bangkok, Thailand, obtained by multi-stage sampling. A self-administered online survey questionnaire with a structured interview was used. The data were analyzed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The results revealed 5 factors of sandal design that meet the needs of Gen-Z consumers, i.e., aesthetic, functionality, symbolism, ergonomics, and innovation. Innovation was found to be the factor that most affected sandal design. According to the results, these factors can be applied to set a strategic plan for more efficient sandal design, which would be useful for product designers, manufacturers, and marketers of the sandal industry in Thailand.

This research objective is to develop a large-scale livestock cow manure processing machine to add economic value and be environmentally friendly. The population was 4,994 dairy farmers in Nakhonratchasima province, Thailand. The sample group was the dairy farmers group in Pak Chong district Nakhonratchasima province, Thailand, with a total of 357 people. By evaluating the rating scale (Rating Scale) five levels of Likert. and there was a confidence value with an alpha coefficient (Cronbach's Alpha = 0.703), which was analyzed by SLR systematic literature review and scamper analysis by synthesizing the data to design new products as three main issues were 1) product creation guidelines from SLR literature review 2) problem diagnosis to the solution with SCAMPER technique 3) new product design in accordance with GOAL data were analyzed by multiple regression analysis and confirmatory factor analysis which found that 1) factors machine features 2) the efficiency factor of the machine and 3) image factors of the machine that resulted positively on farmer satisfaction and explained the farmer satisfaction variance of 71.9%. The standard score regression equation was Z = .453(X<inf>1</inf>) + .384(X<inf>2</inf>) + .465(X<inf>3</inf>) and the regression equation in raw score y = -1.20 + .460(X<inf>1</inf>) + .385(X<inf>2</inf>) + .466(X<inf>3</inf>). When evaluated with CFA, the satisfaction of the sample group of dairy farmers group with the developed cow dung separate machine was found. That is the result of 3 factors according to the model concordance index: χ<sup>2</sup>= .874, df = 4, relative χ<sup>2</sup>= .219, p-value = .928, RMSEA = .000, RMR = .004, GFI = .996, AGFI = .956, NFI = .998, TLI = 1.078, PGFI = .089, RFI = .980, AIC = 82.874.

The research aimed to develop and assess the satisfaction of a sustainable utilization process for dairy cow manure for farmers in the Northeast region of Thailand. The population comprised 162 dairy farmers in Pak Chong District, Nakhon Ratchasima Province, Thailand and the group sampling consisted of 150 dairy farmers in Pak Chong District by using a simple random sampling method to analyze the mean and exploratory factor analysis (EFA). Additionally, dairy cow's dung that was used to be processed into organic fertilizer could reduce methane emission by using a newly developed dairy cow's dung converter, which the organic fertilizer yield was qualified as follows: 1) Organic matter = 14.5% by weight, 2) C/N ratio = 11.24:1,3) electrical conductivity = 4.23 decimals per meter. and 4) the valuable pH = 8.35. Then, the results of the test for the amount of the primary nutrients from the primary macronutrient analysis were total organic carbon = 9.1%, nitrogen = 0.8%, phosphorus = 0.6%, and potassium = 0.84% when using the new converter. Furthermore, it was piloted with a group of farmers in the aforementioned area. From the results, it was found that there were three factors affecting the satisfaction of dairy cow farmers toward the new dairy manure conversion process; namely, the features of the machine, the efficiency of the machine, and the appearance of the machine. Simultaneously, when taking all three factors to evaluate the satisfaction, the following results were found: 1) The features of the machine that is very important (mean = 4.283; SD = 0.661), 2) the efficiency of the machine that is very appropriate (mean = 4.280; SD = 0.528), and 3) the appearance of the machine that is very appropriate (mean = 4.013; SD = 0.632). Then, these three factors were considered as the highlights of the machine for converting dairy cow dung into ready-made organic fertilizer for cultivating plants in organic agriculture that could be seen as being environmentally friendly.

Creation of art as abstract art by choosing a three-dimensional (3D) art form to be used for creativity, has brought the characteristics of the peacock inspired by its forms, color characteristics, including its habitats to be used as a mixture and elements in creating this art. Therefore, when combined with the key elements of a 3D object with depth dimension of the object in the Z axis, adopting the colors of the space and the atmosphere of the peacock's habitat to the surface of the 3D pieces, which provide creative approaches and techniques that enable abstract 3D art to be realized by the shapes and formed by perspectives as a whole. Z-axis can create directions to display hundreds of perspectives. In addition, the colors that have been used to blend in with the 3D objects create beauty inspired by the colors that can be found in nature. The peacock's art has been passed through with the distinctive features of 3D objects, resulting in creating such abstract 3D art pieces.
