The purpose of this study is to examine how time management, usefulness, and interest predict m-learning outcomes. For this study, 144 high school students participated in m-learning activities during science classes. After 5 week of classes, they responded the following surveys: time management, usefulness, interest, satisfaction, perceived achievement and learning persistence. Multiple regression analyses with correlation applied to this study as a data analysis method. The results showed that time management, usefulness, interest significantly predicted learning satisfaction and persistence. In addition, time management and usefulness significantly predicted perceived achievement, Therefore, these findings imply that time management, usefulness should be considered for designing m-learning activities in high school science class.

In the field of dance creation, the use of film and television skills, cyberspace, action sets, computer graphics and other technology and media technology have made the creative environment for dance art that it rapidly improves and presents a new situation. Especially in the dance creation part, VR technology can show many possibilities and can be used as a tool to fully satisfy the choreographer's intention and imagination. Therefore, this study analyzes the acceptance model of virtual reality technology in dance creative education, and we will examine the effect of social influence, shared trust, innovation, interest, and self-efficacy on perceived usefulness and perceived ease. Second, we will examine the effect of perceived usefulness and perceived ease on intention to use. The study is targeted at ordinary dance creators who currently reside in Hebei Province, China. The survey was conducted for approximately 30 days from March 16th to April 17th. The total number of valid samples collected was 377. The results of the identification of the hypotheses between variables based on the questionnaire data are as follows: Firstly, social influence, shared trust, innovation, interest, and self-efficacy have a positive impact on perceived usefulness, perceived ease. Secondly, perceived usefulness, perceived ease has a positive effect on the intention to use. In view of the above research results, the theoretical significance and limitations of this research and the future research directions are discussed in depth.

This study was designed to identify students' perceptions and attitudes towards dictation practice in English listening classes and investigate the relationships among 5 factors with regard to dictation practice: participation, usefulness, interest, motivation, and confidence. For the study, the research was implemented for 15 weeks with 41 Korean university students. The subjects had dictation practice in their English listening classes on a regular basis for one semester. At the end of the semester, a questionnaire was used to find out students' perceptions and attitudes towards dictation practice. For the analysis of the subject's responses, first, a descriptive analysis was administered. After that, a correlation analysis was done to explore what the relations among 5 factors were. Results indicated that most students actively participated in the class, and they regarded dictation as a very useful practice in their listening classes. Also, the dictation practice motivated students not only for English listening but also for overall English studying. However, more than two third students showed low interest and confidence in the class. As for the correlations among 5 factors, there were very strong correlations between usefulness and motivation, usefulness and confidence, interest and motivation, interest and confidence, and confidence and motivation. Based on the results, some implications were presented and some guidelines for effective dictation practice were suggested.

This study was to investigate factors and disclose causal model of the scientific literacy competency about the motivation for science and the scientific literacy competency. The 3 grade university students and the 1 grade university students as pre-service elementary teachers were participated to questionnaire investigation. The data were analyzed by the factor analysis method and the structural equation model method, and the following results were obtained. First, the 3 grade university students and the 1 grade university students perceived the science interest factors and science usefulness factors as the motivation for science, and also revealed the scientific problem recognition factor and the scientific evidence use factor as the scientific literacy competency. Second, the science interest factor had a greater effect on the scientific problem recognition factor than the scientific evidence use factor in both the 3 grade and 1 grade university students. In the path from the science usefulness factor to the scientific problem recognition factor, the science usefulness factor of the 3 grade university students had a greater influence on the direct route to the scientific problem recognition factor than that of the 1 grade university students. In the path from the science usefulness factor to the scientific evidence use factor, the science usefulness factor of the 1 grade university students influenced more on the direct route to the scientific evidence use factor than that of the 3 grade university students.

The objective of this study was to examine antique furniture in the cultural tradition. Through a survey of use and interest in antique furniture for modern living. the methodology included a review of literature in order to determine characteristics of wood furnitures of the Yi-dynasty. A survey of use and interest in antique furniture for modern living was also conducted. The study of interest in antique furniture was limited to five factors of sociopsychological variables : traditional, aesthetic , status symbolic ,economic, and fashionable. Questionnaires were given to the randomly selected men and women in Seoul. Data from 289 respondents were analyzed by $X^{2}$, analysis of variances and correlation. The results were 1) Wood furniture of the Yi-dynasty continued to be of practical usefulness, Antique furniture, therefore, had multiful functional , practical , and aesthetic usefulness in modern living. 2) Interest in antique furniture today was not related to possession or nonpossession, age, and occupation but was related to educational level and socioeconomic status. Suggestions for further research include the study of the organized history of Korean furniture in form, color, materials , and texture. And also included the use additional factors in further research on the study of interest in antique furniture.

This research is a study on smart homes products, which interest and research are being conducted, because of the recent development of the Internet of Things. Consumer's Purchase intention was set as a dependent variable, and technological trust was used as a mediating variable. We used Technology Acceptance Model as background theory. Perceived ease of use, Perceived usefulness, Security, and Brand were set as independent variables. The results of this study are as follows. First, it was found that perceived ease of use, perceived usefulness, and security significantly affected technological trust that consumers feel. Second, technological trust also had a significant effect on purchase intention, and it was found that perceived ease of use, perceived usefulness, and product security, excluding brands, had an indirect mediating effect on consumers' purchase intention through technological trust. This study is meaningful in that by conducting user-centered research, and results that are partially contrasted with existing studies are derived from increasing the interest of factors we used.

Guide robots that provide services in public places have recently emerged as a non-face-to-face solution with the spread of COVID-19 and are growing. However, most guide robots provide only the same level of intelligence and the same interaction in different and changing environments. Therefore, its usefulness is limited and customers' interest is quickly lost. To solve this problem, it is necessary to develop social intelligence that can improve the robot's environment and situational awareness performance, and to continuously maintain customer interest by providing personalized and situational services. In this study, we developed guide robot services based on social HRI components that provides multi-modal context-aware. We evaluated service usefulness by measuring user satisfaction and frequency of use of the service through the survey. We analyzed the service quality attributes to identify the differentiating factors of guide robot based on social HRI components.
