This study analyzed the effects of video characteristics, content characteristics, and innovative diffusion characteristics on the use motivation and the use motivation and the use satisfaction on the sustainability of the use, and also analyzed whether the demographic characteristics (by gender, age, and academic background) play a controlling role in the relationship between motivation, satisfaction of use and intention of continued use. For the research, 520 copies without errors were used for the final analysis after online and offline surveys from March 23 to April 5, 2020. Following is the summary of this study. First of all, to summarize the online video service part, research showed that the most used OTT was ‘Youtube’ getting 398 out of 520(76.5%) answerers’ vote. The most used device for OTT was ‘Smart phone’ with the score of 380 out of 520(73.1%). For average OTT usage time per day, 197 out of 520(37.9%) answerers voted for‘30 minutes to 1 hour’. For place of usage, 369 out of 520(70.9%) answered ‘home’. Lastly, the most preferred OTT contents length was ‘Under 10 minutes’ getting 186 out of 520(35.8%) votes. Second, the ‘information’ and ‘connectivity’ of the video characteristics were shown to affect the 'use motivation' and 'use satisfaction' under statistical significance level, and ‘convenience’ was shown to affect the ‘use motivation’ at statistical significance level, and ‘use satisfaction’ was not affected at statistical significance levels. Third, the ‘quality’ of the content characteristics was shown to affect the ‘use motivation’ and ‘use satisfaction ’at the statistical significance level, the ‘reliability’ was shown to affect the ‘use satisfaction’ at the statistical significance level, and the ‘use motivation’ was not affected at the statistical significance level. Fourth, the ‘innovativeness’ and ‘relative advantage’ of the innovation diffusion characteristics have been shown to affect the ‘use motivation’ and ‘use satisfaction’ at statistical significance levels. Fifth, looking at the causal relationship between mediating variables(use motivation and use satisfaction) and the continuance intention use, the following influences were verified among the variables as a result of examining the influence of motivation and satisfaction on the intention of continuous use, which are parameters that recognize the behavior of user awareness when using online video services. also, ‘use motivation’ and ‘user satisfaction’ of the mediating variables were shown to affect ‘use intention’ at statistical significance levels. ‘use intention’ were shown to affect ‘user satisfaction’ at statistical significance levels. Sixth, whether demographic characteristics(gender, age, education level) act as the adjustment variables for the relationship between ‘continuance intention use’ and ‘use intention’ and ‘user satisfaction’, was verified true. if the adjustment variable is ‘age’(user satisfaction X age), then those in their 20s and 40s are shown to have control effects at statistical significance levels. if the adjustment variable ‘education level’(use motivation x education level) and (user satisfaction x education level), the Ph.D. course/doctor was shown to be effective at statistical significance levels. it was found that ‘gender’ had no adjustment effect at statistical significance level in relation to use motivation and user satisfaction and continuance intention use. This study is meaningful in that the scope of the study was expanded by empirically verifying the use of online video service (OTT), and the significance of this study is that a plan to utilize it strategically was derived.

In wood furniture production, utilizing hardware plays a significant role in enhancing quality of design, and have a direct effect on productivity and convenience as well. Up to the present, although there are diverse hardware in furniture making, it is hard to find cases inside and outside of Korea using embedded square lumber hardware that fixes square lumbers from three ways by meeting them on one point at the corner with 45 degrees. Even though three-way miter joint technique has been continued as one of traditional furniture making method, this is hard to be generalized because this demands high level of skill as well as has limit in production. For these reasons, the researcher proposes corner joint hardware for wood furniture using 3d printing. For developing three way miter joint hardware, this study starts with researching a term of three-way miter that is generally mixed with several ways of meanings. Secondly, the author researches structure of three-way miter and case study of its application example between traditional and modern wood furniture. In detail, researcher analyze structural character in furniture connector focused on fixing example between square lumbers for utilizing 3d printing. As for prototyping, 3D printed fixing connector is combined with existing square lumber joint system to strengthen and make up pros and cons of each part has. In this phase, 3D modeling and 3D printing is used for mock-up, and before and after image of combining 3d printed hardware is suggested. In this study, three way miter joint hardware has embedded structure, which is invisible outside. This can expect ornamental effect caused by molding and groove process on wood furniture that may looks simple. More simplified production process than traditional one would elevate productivity and access to wood furniture design with natural grain, and also be useful for corner joint that consist of square lumber including shelves, storage cabinets and table as well.

On-demand service is the industry model that is currently developing the most. On-demand services use content using platforms such as mobile applications. Therefore, a high-quality user experience of content leads to a customer experience. Therefore, content UI design is also a factor influencing the on-demand service customer experience improvement. esponsive design is a UI design that responds to screen size in web design. However, it has become a design trend due to the generalization of responsive design, and responsive design trends such as the use of grids, card layouts, and metaphors are applied in various UI designs. Accordingly, this study studied the improvement of customer experience of responsive design-based on-demand service content. Through the composition of expert councils, the types of on-demand services were categorized into four types: content, employment, sharing, and distribution, and responsive design was analyzed in terms of sortability, readability, implication, and variability. In addition, the effect of the elements of responsive design on improving the customer experience of on-demand service was studied by using the statistical analysis method through a questionnaire. As a result, the content type was readability, the employment type was implied, the sharing was sorted, the distribution was sorted, the readability, and the implied customer experience improvement factors were derived. It is expected that the results of this study will be used as basic data for the production of content related to on-demand services in the future.
