The purpose of this study is that we regard the notion of reality that television viewers feel as presence, point out problem of measurement tool that appropriate for TV, clarify the subordinate concept of presence, and develop measurement tool that have reliability and validity. To achieve this, we paid attention to reality of television as a determinant of presence and tried to elicit proper subcategories. That is, we progressed two steps research that distinguished external characteristic and content of the media into sensible reality and cognitive reality, and develop measure item and verified statistical validity. We analyzed the second research result about measurement category of presence selected by first research and then we did Exploratory factor analysis and Confirmatory factor analysis. As a result, the first characteristic that make people experience presence is sensible reality, that is, it is the factor of sensible faithfullness, image faithfullness, and image reality as the form factor of the media. The second characteristic is cognitive reality. That is the factor of social reality, relational reality, and practical reality as the factor of media content. Synthesizing these subordinate factor, we can conceptualize presence experience as a reality of media form and content in HDTV viewing environment.

We studied what kind of science-contents problems can also give information on one's creativity for use in the selection of scientifically gifted. 383 7th and 8th graders as subjects, we first analyzed the corelation between the results of creative thinking, scientific attitude, science inquiry, logical thinking and the scientific creativity problem solving skill test. The corelation analysis indicated that science inquiry test could represent other tests except TTCT. We then tested 532 6th graders with TTCT and science inquiry tests concomitantly with the contents- related problems made in such types as naming 20 scientists, writing about a scientist, imagination to overcome a problem, understanding of theory and application and understanding of science laws and application. The results indicated that writing and imagination were most efficient in assessing both the contents and the creativity.

The development of information system and communication gave us new education model, called remote education. And the remote education, being free from constraint of time and space and using various multimedia resources, has helped and substituted public educations, and has enlarged the area because of a lot of advantages and educational possibility compared to public educations. But it is very insufficient to study on analysis system which can analyze the learner and improve the educational process compared to various contents and education methods. In this study, we realized web-based item pool system which can remove the inefficiency of making duplicated and one-time used questions and which can manage and evaluate learners' achievements more efficiently. This program can give us quality improvement of remote education by raising efficiency of production with various pattern of paper making and item pool type management of items made and by executing high quality analysis with various pattern to the learner.

It has been determined the 6 core competencies of our university students. Among them, it was judged that the student's convergence thinking ability and self-development ability were insufficient. To enforce the two insufficient abilities, an engineering-related major collage course was newly established in the form of an intensive coursework. The course was conducted as a shared curriculum between division/departments. For each of the first and second semesters in the 2020, 54 students from two completion groups (Department of Electrical and Electronic Control Engineering; 26, Optical Engineering; 28) were the subjects of the survey, the survey results of 20 common questions were comprehensively analyzed. As the result, more than 75% of the respondents were positive about free online learning at any time and place. And if additional interactive activities and team teaching method are reinforced during recorded audio and video contents learning material, It is confirmed that the attempted intensive course can maximize the learning effect.

This study was performed to develop menu satisfaction index in Business & Industry (B&I) food service and to survey customer's menu satisfaction using the index. The menu satisfaction index included 16 items with Likert 5 point. Cronbach's alpha to assess the internal reliability of the developed scales was 0.8917, which indicated highly reliable. Construct validity was assessed by principal components analysis and then four factors explaining 65.964% of the total variance were found. Among the 15 items of menu satisfaction, the average scores of all items were above 3.0 out of 5. As a result of analysis on menu satisfaction factors, 'propriety of food temperature' (3.52 out of 5) was the highest consideration followed by 'sufficiency of format' (3.46), 'excellence in food' (3.35) and 'well-being orientation' (3.31). It could be said that customer's perception on the menu quality was very positive. Four factors were correlated with overall menu satisfaction positively. Especially, 'excellence in food', and 'well-being orientation' and 'sufficiency of format' affected significantly on overall menu satisfaction. It concluded that customers were satisfied with portion size, temperature, price but their needs for taste and health/nutrition-related service would be increased. The menu satisfaction developed in this study should be applied to other B & I food service operation by type.
