    This research had the objective to design children’s bins and make a comparison of the new and old bin patterns. The group sampling consisted of 652 participants composed of the students and personnel in a school in Khlong Kum District, Bangkok, Thailand. For this case, multistage random sampling was used with 234 participants, and the research tools were composed of five-point Likert scale questionnaires that were measured with Cronbach’s alpha coefficient with a level of 0.91, independent t-test and multiple regression analysis. From the above information, it was found that the influencing factors to the children’s bin’s design involved the beauty (0.32), specific attributes, (0.24), morale (0.16), ergonomics (0.10), safety (0.07), application (0.07), and the materials (0.05). In addition, when testing the model, it was found that the new bin product patterns had the most satisfaction level (X=4.55; S.D.=0.30), followed by the original bin product patterns that had a moderate satisfaction level (X=3.08; S.D.=0.52). Finally, when comparing the differences of the satisfaction level by using the t-test statistics, it was found that the children’s satisfaction to the new bin patterns were at a higher level than the original ones with a statistical significance level of .05.

    This research used a mixed-methods approach to focus on the properties and satisfaction assessment of effectiveness for palm fibers in the Khonsan Sub-District community group in Chaiyaphum province with a total of 113 people. In addition, the study used a 5-point rating scale which had a Cronbach’s Alpha Coefficient value at the level of 0.97, in addition to two-way ANOVA. The study presented testing results by ordering from coconuts, palms, betel nuts, and tans with the fiber tensile ratings of 67.45 N, 57.19 N, 56.75 N, 52.49 N, and fiber tensile ratings of 6.80%, 7.30%, 7.12%, and 6.25%, respectively. In this case, the betel nut fibers and tan fibers showed durability to wet washing and the dry period as the most common way. Thus, the satisfaction assessment of tan fibers was at the most satisfactory level, (Mean=4.49, S.D. =0.57), followed by the coconut fibers at the excellent level, (Mean = 4.47, S.D. =0.56) and the betel nut fibers at the moderate level, (Mean=3.35, S.D. =0.71). Levene’s test showed that p was equal to 0.00, indicating that the factors of type and properties of palm fibers were at a varied level with statistical significance. Similarly, the fiber characteristics and properties of palm fibers for each type had an F value equal to 11.45 and Sig. equal to 0.00. In addition, it was found that there was at least one pair different from other pairs, such as coconut fibers and tan fibers. Consequently, the research with community participation showed that it appeared to confirm the balance between the effectiveness of materials, labor skills, human labor, and the stabilization of life. As a result, it affected the satisfaction at the excellent level for people in the development communities (Mean=4.10, S.D. =0.78).
