Since most information is readily available these days, the shear volume of the information simply overwhelms people, rather than helping them as a form of useful knowledge. Thus, the quantity of information someone owns doesn't possess much significance. The possibility to well-utilize the quality information is much more important these days. Electronic culture map service is being provided these days to introduce various cultural information to people around the world. But its service is limited to 'visualization, collection, and integration of the data.' Which means, electronic culture maps are no more than a simple data collector. The main purpose of this thesis is to develop a new kind of knowledge/information service method which overcomes these shortcomings. To achieve this goal, at first, the thesis will take a close look at the characteristics and functions of Chosunjock culture maps, and then, it will clarify the definition of data, information, knowledge of cultural resources. And secondly, nd thirdly, the thesis will look up the Wayfinding contents, User Experience Design, User Context, and Organic design for knowledge/information service. And lastly, the thesis will develop the knowledge/information service, specifically based on Chosunjock cultural resources.

The aim of this study was to understand the difference between the image of social-workers and nurses perceived by middle school and high school students, and determine the experience related to social workers and the role of social workers projected in the media. The subjects of this study were 386 students of middle and high school located in S city. Data were collected from Oct. 15, 2013 to Nov. 23, 2013 and analyzed using the SPSS win 18.0 program. A comparison of the image of nurses and social workers in two groups showed that middle school students tended to have a more positive image of nurses than high school students, and the image of nurses appeared to be more positive than that of social workers. As a result of analyzing the contents exposed in media, the students received most of their information on social workers from TV. Therefore, it is necessary to have a strategy to help students choose a major or a job by reinforcing mass media monitoring based on TV, which may have a major impact on the image of social workers and provide them with the correct information on the profession.

In recent years, 3D displays are used in many media including 3D movies, TV, mobile phones, and PC games. Although 3D displays provide realistic viewing experience as compared with 2D displays, they also carry issues such as visual fatigue or size distortion. Focusing on the latter, we developed prediction function of object size perception as a function of object depth in 3D display. In Experiment 1, subjects observed 3D square of a fixed size of varying depth, and manipulated 2D square to make it as large as the 3D square. Conversely, in Experiment 2, subjects observed 2D square of a fixed size, and manipulated 3D square of varying depth to make it as large as the 2D square. In both Experiments 1 and 2, we found that size perception of 3D square linearly changed depending on depth of the square, and the linear relationship between depth and size was identical in both experiments. The predictive regression function, which predicts object size perception based on object depth, obtained in this research will be very useful in the creation of 3D media contents.

Objectives : Because elementary school children are sensitive and prevalent to dental caries, oral health care program for the elementary school children (ESOHCP) should be met the first priority for the national oral health care program. This study was performed to proposed the guidelines for executing the efficient ESOHCP through the evaluation of present oral health care and education status based on the attitudes and opinions of health teachers. Methods : Subjects were 181 health teachers those are a part of the total 273 elementary school health teachers in Busan. From April to June 2001, questionnaire survey on the teacher's attitude and opinion, present status of oral health care and education in their own school was done. Data was analyzed by $\chi^2$-test, t-test, ANOVA using SAS (ver 6.21) program. Results : Mean age of the teachers was 40 years (24~58 years) and mean scale of the subject school was 32 classes (5~58 classes). Above 90% of them agreed with the necessity and importance of ESOHCP, but actual level of concerning was lower. They gained the informations about oral health mainly from media (33%), PC net (26%), academic society (25%), and more used internet (p=0.012) in younger generation. Though most of them (96%) had a specified school dentist, only 58% had the experience of periodic oral health examinations in their own school. The major experienced ESOHCP was fluoride brushing and contest to choose the best healthy teeth. Oral health education given by the teachers was not professional but their own. About half (42%) of the teachers had never taken education during last one year. Major education materials were VTR tape (79%), teeth model (64%), CD (55%), booklet (50%), etc., and the teachers' preference was also VTR tape (43%) and CD (41%). When they need education materials, they frequently request to dentist's association (36%), academic society (35%), but rarely to dental clinics or dentists (6%). They prefer that two times (46%) of annual oral health education, with the contents of regular brushing (53%), but lower regular visit to clinics (13%). The interest to oral health care (p=0.016) increased with teacher's age. And, they agreed regular students education in case of higher interest(p=0.044). Intention about join in the model school program was decreased with scale of school (p=0.002). Conclusions : This result showed that the present status of ESOHCP is still insufficient. It considered that the health teachers' interest and role is most important for the maintenance and success of ESOHCP. The professional and efficient education program would be focused on the health teachers to induce drive on ESOHCP.

Teachers are the most important factor contributing to determining the quality of education. Therefore, the quality of teachers should be improved to enhance the quality of education. Teacher's competencies are defined as the skills required for teaching profession, that is, the ability to perform not only in teaching activities, but also in guidance and class management. The purpose of this study is to analyze the competencies of science teachers that elementary, middle and high school students want. To this end, 332 elementary, middle and high school students were asked to describe their preferred science teacher's competencies and avoiding science teacher's competencies as an open questionnaire. The resulting concepts were analyzed by semantic network analysis (SNA). The results of this study are as follows: 1) The competencies of science teachers that students prefer varied. This suggests that most students think positively about science teachers. In addition, it is possible to show students the positive or preferred competencies of teachers in various ways. 2) The students wanted teachers to explain the theories and concepts related to scientific phenomena through experiments. They also preferred hands-on activities and experience in science class. 3) The students put emphasis on the class-related contents in the competencies of science teachers. Accordingly, the image of science teachers and science itself should be enhanced through the improvement of science teaching methods and positive attitudes toward students. It is expected that further research on the image according to specific teaching methods of science teachers will be conducted based on the findings of this study.

The ultimate goal of a hardware design course is to equip the students with the system design ability. However, the majority of the current structures of the design courses are focused on the understanding of the operational principles of each device which is used later as a building block for the design of a system. The shortcomings of this approach are, first, that it is very hard to keep the students motivated to the end of the course where system design concepts are dealt, and, second, the students do not have enough experience of the system design which is usually required in the field. As an alternative to solve these problems, it is necessary to reverse the order of contents of the course. Namely we introduce the high level of the abstract concept of the system design in the very beginning of the course and later by lowering the level of abstraction to the operational principle of the internal devices. In this paper, we propose a new top-down methodology for the introductory hardware design course of logic design, where the design expression and verification in the system-level are introduced first and then detail knowledge on each device is introduced later. Also, we report a case result from a student's working group as part of an extracurricular education in order to verify the validity of our proposed approach

The purpose of this study was to analyze the perception of academic difficulties of middle school students and their influences variables in technology subject. The subjects of this study were middle school students in the whole country. A total of 420 students were selected considering the grade and area for the survey. The data were collected by mail and analyzed using SPSS 22.0K. The results of this study were as follows : First, The academic difficulties perceived by middle school students in the technology subject were recognized as normal. Second, Middle school students perceived it as a lack of experience (opportunity) in the technology domain as a cause of academic difficulties. Third, In the learning process, the female students were more difficult to understand the related terms and theories than the male students. In the problem solving activities, the female students were more difficult than the male students in identifying problems, designing solutions, selecting solutions, modeling, testing solutions, and correcting improvements. Fourth, the academic difficulty in learning technology lesson was difficult in terms of terminology, theory, and practice activities in the order of Second, Third, and 1st grade. Fifth, lack of understanding knowledge, confusion of contents knowledge, lack of technical interest, shortage of class hours, lack of understanding of evaluation criteria were all influenced by the difficulty of technical subject learning. Sixth, the academic difficulty influencing the problem solving process was explained by understanding comprehension, content knowledge confusion, technical interest, class time, understanding of evaluation criteria.
