This study examined the relative importance and the most preferred level of factors which were identified through the readability researchs. For this. subjects were given a text constructed in usual letter width with square form letter or non-square form and then. ranked the preference between the text factors. In experiment 1 where a text was printed in square letters. letter size was rated as the most important factor followed by line spacing letter width, line length, letter spacing, line justification, and letter form. But when non-square letters were used in experiment 2. the second most important factor was the letter spacing although letter size still topped the list. These findings indicate the differences in letter designing principles for various types and the unfamiliarity to non-square letter forms for general public. Unlike inYi and Jin(1998) where letter width turned out to be the most sensitive factor, the highest priority should be given to letter size when publishing with usual letter width.

The purpose of this study is to elucidate the effects of a new clinical training simulator for dental radiography using augmented reality (AR) on user learning context. To accomplish this purpose, we divided 217 dental hygiene students into two groups. The experimental group was presented with the new clinical training simulator for dental radiography using AR, and the control group was presented with task information using a textbook. The results showed that the experimental group presented the new clinical training simulator for dental radiography using AR had a higher level of self-efficacy, interest in learning, flow, and practice satisfaction compared with the control group shown the task information using a textbook. Therefore, the AR-based radiography simulator can be utilized in dental radiology practice education as an effective educational device.

Five Plus One' is a result of visual expressions on five senses such as the sense of sight, hearing, smell, taste, and touch. Although I searched for the data on five senses, there were only information which was quoted in various languages and scientific bases, and also most of the books written were far from artistic expressions including visual pleasure and emotional expressions. In addition, most materials were mainly textbooks for children's intellectual development, academic papers, and medical publications. Therefore, I made this book that makes us to communicate about five senses and an inspiration even though we have a problem to read writings in both Korean and English. I arranged visual elements using illustrations and typography in various ways based on the scientific evidence.

When we deal with grouped statistical data, it is desirable to use a calculation method that gives as close value to the true value of a statistic as possible. In this paper, we suggested a new method to calculate the quantiles of grouped data. The main idea of the suggested method is calculating the data values by partitioning the pentagons, that correspond to the class intervals in the frequency polygon drawn according to the histogram, into parts with equal area. We compared this method with existing methods through simulations using some datasets from introductory statistics textbooks. In the simulation study, we simulated as many data values as given in each class interval using the inverse transform method, on the basis of the distribution that has the shape given by the frequency polygon. Using the sum of squares of differences from quantiles of the simulated data as a criterion, the suggested method was found to have better performance than existing methods for almost all quartiles and deciles.

It is necessary for young children to integrate the sense of sight, hearing, touch, etc. for developing their emotion and cognition. Thanks to Information and Communication Technology (ICT) development, young children have more opportunities to use various senses in learning process. However, ICT learning method is more focusing on the sense of sight and hearing, and lacks of integrated recognition and this fact leads to the reason why ICT can not be used as a main education tool. Therefore, this study evaluated the influence of wUbi-Pen(haptic device) on cognition using a computer puzzle program. The results show that young children using a haptic pen have greater intention and performance in object assembly, mazes, picture completion in K-WPPSI test than those of non-using haptic pen. This implies that haptic function should be considered in ICT material and indeed useful in various cognition-related symptoms and diseases.

Knowledge-based society requests the ability to reuse existing knowledge beyond acquirement and utilization of universal knowledge. The present education of computer, on the other hand, is biased only teaching how to use software. But it does not appropriate for the education to boost various and creative thinking. Thus, this paper carried out research on creativity to be treated in the goal of the 7th Educational Curriculum. Also it selected and analysed computer programming languages-'LOGO' and 'Scratch'. Furthermore, it develops a training material and applies to elementary students in schools. The result that it compares and analyzes the effect that each languages influence to creativity of students, both of them help to develop creativity. Especially 'LOGO' made a positive impact on fluency, 'Scratch' did on ness and resistance.

Fashion design education essentially requires not only a theoretical but also a practical process in which feedback comes through personal interactions between an instructor and a student. But the existing WBI system exemplifies its limitations by applying only a one-way Distance Education methodology that limit interactions based only on the theoretical texts. This study affirms that distance learning system is possible for the applied component of the fashion design curriculum as long as the specific needs of the particular program is taken into consideration and systematically applied. So it designed and applied an original web-based distance educational system specifically incorporating the needs of the fashion design curriculum Thus the results show that the enhanced distance education system is a tool that could be effectively utilized with the same degree of success as the traditional classroom as long as the traditional teaching component of direct interaction necessary to the fashion design program is incorporated.

The very first statistics department in Korean universities was founded in 1962, meaning it has been 57 years since Korean academia has regarded statistics as a wholly independent field of study. Dr. Junbo Kim was the first faculty member hired by Korea University's statistics department. He made a seminal contribution to the development and publication of statistics textbooks in those early years, and in 1971, spearheaded the efforts to found the Korean Statistical Society, serving as its first president. Naturally, Dr. Kim's significant contributions have laid the cornerstones for the advancement of statistics as an independent field of study in Korea. In this paper, I will explore two main subjects: one is the early history of the Korean Statistical Society with a special emphasis on Dr. Kim's contributions, and the other is an analytical overview his publications. Specifically, I will focus on Modern Statistics: A Synthesis of Statistics and Estimates』(Kim, 1954), and 『Inferential Statistics: An Introduction to Sample Survey and Experimental Design』(Kim, 1956).

The illustrations in elementary science textbooks and experimental workbooks based on the 7th national curriculum were analyzed for gender-role stereotyping, and compared with those of the 6th curriculum. The frequencies of men and women who appeared on text illustrations were counted and the types of roles assigned to males and females were investigated. The results were as follows. 1) The 7th national curriculum textbooks contained double the numer of illustrations in the textbooks based on the 6th curriculum. 2) Boys and girls were illustrated in 'learning activities' with equal frequency, but boys were more frequently represented than girls in illustrations of 'other' activities. 3) Both boys and girls were generally depicted in 'active' processes and the ratio of 'passive girl' illustrations decreased as compared with the 6th national curriculum. 4) Male adults were more frequently represented than female adults in both textbooks and experimental workbooks. 5) 40% of female adults were illustrated doing housework, while male adults were rarely illustrated in such a role.
