The purpose of this study is to compare and analyze the impact on low-achievers in mathematics who studied mathematics using Blended e-learning and Personalized system of instruction after school. Blended e-learning is defined as the management of e-learning using the e-study run by the education office in local. Personalized system of instruction was proceeded as follows; (1) all students are given a syllabicated learning task and a study guide, (2) students study the material autonomously according to their own pace for a certain period of time, (3) the teacher strengthens the students' motivation through grading and feedback after students study a subject and solve the evaluation problem. The learning materials for Personalized system of instruction are re-edited the offline education contents provided by the blended e-learning to the level of students. The 118 $7^{th}$ grade students from the D middle school participated in this study. The results were verified by achievement tests before and after the study, as well as survey regarding their attitude toward mathematics. The results are as follows. First, Blended e-learning has more positive impacts than Personalized system of instruction in mathematics achievement. Second, there was no difference in mathematics achievement according to their self-directed learning between Blended e-learning and Personalized system of instruction. Third, both types utilizing Blended e-learning and Personalized system of instruction have positive effect on attitude toward mathematics, and there is not their difference between two methods of teaching and learning mathematics.

We performed the subjective sensibility evaluation on knitted fabrics by the following procedures: setting acrylic fabrics used for S/S among fabrics as basis, five kinds of blended spun yarns and four kinds of twisted filament yarns made by different twisting methods then, we did questionnaire survey targeting sixty females in the expert groups. Utilizing SPSS 12.0, correlation, ANOVA, Duncan, and Multidimensional Standard way were analyzed. The results are as following. First, the result of evaluating on preferred knits followed by the analysis of the sense factor, in the 'drape sense', the acrylic/rayon blended knit was preferred as the most flexible, pliable, and elastic knit; in weight/bulk factor, the acrylic filament knit the most twisted was preferred as the least bulk, thin, cool and transparent knit; in 'surface depression sense' factor, A(F)W acrylic/wool blended knit was preferred as the most haggard, straight, dry knit. Second, the result of evaluating on preferred knits followed by the analysis of the sensibility factor, in the 'neatness' the acrylic filament hit was preferred as the most clean, neat and delightful knit; in the 'comfortableness', the acrylic/wool blended knit was preferred as the most natural, stable, and comfortable knit. Third, according to the result of evaluating on preferred knits as the spring and summer, generally the acrylic filament twisted yarn knits were more preferred than the acrylic blended yarns.

Background: To investigate the mediating effect of learning flow in the relationship between blended learning achievement and learning satisfaction in dental hygiene students, and to identify whether face-to-face studies should be substituted with non-face-to-face studies. Methods: Total 134 dental hygiene students, who underwent blended learning in the dental hygiene class during the first semester of 2021, were recruited. The research tools were blended learning achievement, learning flow, and learning satisfaction, comprising 15 questions in total. Mediation regression analysis was used to analyze the mediating effect of learning flow in the relationship between learning achievement and learning satisfaction, and that between each variable. Results: Learning flow and learning satisfaction (r=0.490, p<0.001) were positively interrelated, and the interrelation between variables was statistically significant. Class environment had the biggest effect as a subfactor of class achievement, and it appeared to have an effect on class attitude and learning motive. The effect of learning flow on learning satisfaction was statistically significant. Learning flow was partially mediated by both blended learning achievement and learning satisfaction. Learning flow was directly related to blended learning satisfaction and learning achievement. Conclusion: The results showed the possible use of blended learning in dental hygiene theory and practical subjects.
