This study investigated the effect of self-efficacy on the usage intention of the size recommendation services, exploring the mediating roles of perceived ease of use and perceived usefulness. Moreover, it examined the moderating effects of filtering types on these relationships. Data were collected from 200 participants between December 11 and 13, 2023, using virtual scenarios and stimuli. Mediating and moderating effect analysis were performed using a process macro. As a result of path analysis and indirect effect analysis between individual variables, it was confirmed that the direct effect of self-efficacy for the size recommendation services on usage intention, and the indirect effect on usage intention through perceived ease of use and perceived usefulness were significant. Furthermore, as a result of the moderating effect analysis, it was found that the moderating effect of the filtering types was significant in the relationship between self-efficacy and perceived ease of use, between perceived ease of use and perceived usefulness, and between self-efficacy and usage intention.

In this paper, a disassemblability evaluation has been investigated quantitatively by using an ease-of-disassembly design method. Four categories such as recognizability, approachability, separability, and treatability have been analyzed in details. A simulation software for estimating the ease-of-disassembly design method has been developed and applied to door trim and spin basket respectively as an example.

The subject, in the blouses that sleeve caps and sleeve lengthes are different from, did sensory test by right arm movement and both arms movement. This sensory test which is used in fabric good, is Shef's. RESULTS : 1) The ease of bust size is very significant by cap height, at 5%, 1% level by sleeve length. 2) The front area of arm hole is affected by cap height, sleeve length movements more than the back and the under area of arm hole are 3) Sleeve width is affected by cap height, sleeve length both arms movement. That is, they should be designed according to the use because they affect the ease of blouse very much. Especially bust size should be considered with sleeve pattern because the ease bust becomes different with sleeve pattern.

In this paper, a redesign of an existing computer case is Proposed by applying some guide lines of assembly and disassembly which have positive effects on environment. Some problems such as Increase of number of disassembly and vibration, and unfittable difficulty in assembly and disassembly of coy-ers are recognized through analysis of geometrical structure in view of both assembly and disassembly. A solution of these problems is proposed by ideas of positive environmental influence through ease of assembly and disassembly. Design for Environment Software is used to evaluate both redesigned and existing products. Time of assembly and disassemb]y and MET-point are especially calculated by the software, and these data give us a good guide for analysis of ease of assembly, ease of disassembly and environmental influence in both products.

This study was examined empirically the relationship between exogenous and endogenous variables to use internet shopping malls. Exogenous variables in our model are retrieval simpleness, quality of order treatment, web reputation, update and system quality and endogenous variables are perceived usefulness, perceived ease of use and intention of using internet shopping malls. The results of the path analysis are shown as follows. All exogenous variables have a direct effect on perceived ease of use while both retrieval simpleness and update has a direct effect on perceived usefulness. The perceived ease of use has a direct effect on the intention of using internet shopping malls and has a indirect effect on the intention through perceived usefulness. Especially, web reputation among the exogenous variables has the strongest impact on the perceived ease of use and retrieval has the strongest impact on the perceived usefulness.

The purpose of this study was for analysis of ease about basic bodice pattern, as the first step of the research process for the drawing method of basic bodice for women in their twenties. The five selected basic bodice were made and they were worn by FRP body The garment space of each bodice was measured by analysis of the garment space of each section in figure of polymerization of cross section by a 3-D measuring instrument. The research suggests that this compared analysis is an objective reference. This analysis not only of the area of cross section of garment space and ease but also of the girth of the body shape and wearing shape, using the PAD system and 3-D measuring instrument, can be helpful in making garment patterns.

This study analyzed the learning effect on K-MOOC. It was confirmed how the ease and interaction of K-MOOC affects learning satisfaction and Learning Persistence. The results of the study are as follows. First, it was found that the interaction and ease of K-MOOC learners had a positive effect on learning satisfaction. Second, it was found that the ease and interaction of K-MOOC learners had a positive effect on the Learning Persistence. Third, the satisfaction and willingness of learners with prior course experience of K-MOOC learners were high, and there was a significant difference according to the course experience. This study is meaningful in that the effect of actual learning activities was verified for K-MOOC learners. Based on the results of this study, it is necessary to conduct a comparative study on the K-MOOC activation plan and the case of using K-MOOC at each university.

This study analyzed information privacy concerns and personal innovation influences effects of perceived usefulness, ease-of-use and satisfaction for a smartphone-based shopping mall, using technology acceptance model. For empirical analysis, the structural equation modeling analysis method was used. The results are as follows. First, information privacy concern is the usefulness of smartphone-based shopping mall has significantly negative, but did not affect the ease of use. Second, personal innovation is the usefulness and ease of use smartphone-based shopping mall have significant positive effect. Third, ease of use smartphone-based shopping mall is usefulness and satisfaction have significant positive influence. Finally, the usefulness of use of the shopping mall based smartphone significant satisfaction in positively influencing.

This study looks deep into how user's individual personality and his or her media experiences affect perceived usefulness and perceived ease of use about UHDTV based on Technology Acceptance Model using survey methodology. This study also focuses on how the purchase intention of terminal equipments and the willingness to pay for UHD contents will make different choices. The result of this study shows that, whether user is an exhibitionist or not or has frequently encountered a big screen, these factors affect both the perceived usefulness and the perceived ease of use about UHDTV. When user is an exhibitionist with more experience with big screens, it was clear that user tended to choose UHDTV with higher perception of usefulness and ease of use about UHDTV. This study also implies that when supplying the next generation broadcasting service, it is needed to consider the users' perceived usefulness and ease of use about UHD as well as the individuals' media experiences and characteristics.
