The purpose of this paper is to find a method of measuring mathematical creativity reasonably. In the pursuit of this purpose, we designed four multiple solution tasks that consist of two kinds of open tasks; 'tasks with open solutions' and 'tasks with open answers'. We collected data by conducting an interview with a gifted fifth grade student using the four multiple solution tasks we designed and analyzed mathematical creativity of the student using Leikin's model(2009). Research results show that the mathematical creativity scores of two students who suggest the same solutions in a different order may vary. The more solutions a student suggests, the better score he/she gets. And fluency has a stronger influence on mathematical creativity than flexibility or originality of an idea. Leikin's model does not consider the usefulness nor the elaboration of an idea. Leikin's model is very dependent on the tasks and the mathematical creativity score also varies with each marker.

"Saving lives by curing the world is the way of sages" is one of the key concepts from Daesoon Jinrihoe's The Canonical Scripture. In the Daoist scripture, The Most Excellent and Marvelous Lingbao Scripture of Limitless Salvation (The Salvation Scripture for short), a similar idea of 'saving the world and liberating lives' can be found, and it parallels the idea of religious healing in Daesoon Jinrihoe. Both systems of thought are internally consistent and focus on the individual living being as well as society by taking aim at curing human diseases while solving societal problems. Both sources also took influence from earlier Daoist Thought that responded to The Book of Changes, extended their innovations to traditional medicine, and realized the usefulness of religious healing. Although the two developed in different countries and time periods, their ideological similarities can still be appreciated. This paper delves into the above topic via three aspects: first, analyzing the historical background that produced Daesoon Jinrhoe's concept of "Saving Lives and Curing the World" while covering both individual and societal applications, second, examining the methods of implementing "Saving Lives and Curing the World" as a form of religious healing, and third, comparing the philosophical similarities between Daesoon Jinrihoe's "Saving Lives and Curing the World" and Lingbao Daoism's The Salvation Scripture in terms of their religious thought.

The visual humor can be regarded as an original source for creative ideation. There are several types of humor. for example,'wit, satire, irony and so on. These can be motivations of developing an up-to-date idea. Wit differs from most humor in being purely intellectual, rather than relying on incongruities that come up naturally in many situations. The humor of words contains pun, hyperbole, repetition, and comparison or contrast. Especially in case of pun, it can be most important type of humor for making analytical and humorous effects visually. Pun, meaning the humor of double meaning, furnish us with much of our humor. The concept of pun is the most valuable for creating the visual humor by substituting, combining and manipulating symbols. There are essentially three distinct categories of puns : the literal pun, the suggestive pun, and the comparative pun. All types of puns belong to one of these three groups. The definitions are simple to understand and easy to apply for creating the visual humor, In order to develop a better conceptual model, (this researcher) reexamine the concept of humor, the relationship of humor to various types of message processing, and the relationship of humor to various aspects of message. This thesis. is primarily concerned with basic theories of humor such as concepts of humor, types of humor and analysis of humor. And this contains the research of humor's communications effects and theory of humor response with literature reviews. Modem theories of humor response generally fall into three major schools : Incongruity theories, Superiority theories and Arousal (Relief theories. Together these three approaches address the cognitive-perceptual, affective-evaluative and psycho-dynamic dimensions of a subject's humor response. The literature research of humor and humor response theory in communications and visual communications can help the visual application of humor concepts and usefulness of visual humor appeals. This research agreed that the humor and visual humor must be very effective at being as a means for the advertising expression, not for the purpose itself. In addition, this research is aimed at studying significations and usefulness of visual humor through semiotic approaches in the near future. Then it can be essencial research for the appropriate situational uses of humor related to media, product, and audience factors, such as nationality, age, standard of living, sexuality, and so on.

This study aims to compare self- and peer-assessments of science-gifted elementary students' scientific creativity. A science-gifted program on the Pascal's principle was implemented to 40 fifth-graders in the Science-Gifted Education Center for two weeks. After that, students presented their results from a scientific creativity task using the principle in class. The task was to devise a new and useful tool using the principle, and it included the students' self-assessment about their idea. During presentation, students were asked to assess the works of peers and write down the reasons that they gave the scores they gave. Shortly, student self- and peer-assessments about students' scientific creativity outcomes were compared. Based on two essential components of creativity, ideas that satisfy both originality and usefulness can be counted as scientifically creative. The main results of this study are as follows: First, the average scores of student self- and peer-assessments were 71.5 and 61.9. Second, the standard deviations of student self- and peer-assessments were 14.47 and 5.79. Third, among scientific creativity, originality, usefulness scores, only originality had a significant correlation between student self- and peer-assessment (r=.42). Fourth, the students were categorized into four groups according to the levels of their scores by student self- and peer-assessment. And the frequencies of peer-assessment group had a significant difference at p<0.05 level, according to self-assessment group (Chi Square=4.0000, df=1, p=0.0455). Fifth, through a case study by group, the results suggesting that self-assessment could be affected by the students' self-efficacy and perfectionism and such effect could also influence peer-assessment have been found. The result showed that how the student self- and peer-assessment of scientific creativity are different and what the students' thoughts on the evaluation of scientific creativity are. The findings suggested that there are several things to consider for the educators to make efforts to construct consistent assessment methods for scientific creativity.

This study investigates Kim Inhue's view of reading through the analysis of reference books in Haseo-Chunjib(하서전집). As the result, he had read 123 different books ar least. He had quoted frequently $Sish{\bar{u}}$ $S{\bar{a}}nj{\bar{i}}ng$(사서삼경), $Sh{\check{i}}ji$(사기), $H{\grave{a}}nsh{\bar{u}}$(한서), $Zhu{\bar{a}}ngz{\check{i}}$(장자), $G{\check{u}}wenzh{\bar{e}}nb{\check{a}}o$(고문진보), $Ch{\check{u}}c{\acute{i}}$(초사), $W{\acute{e}}nxu{\check{a}}n$(문선). He had read books beyond the contemporary(sixteen centurtry) scholar's common list, and had enjoyed reading over the boundaries of stereotyped idea. While he had emphasized on the scripture of Confucian, had earned more knowledges for usefulness and the bases of scholarly writings by reading a wide spectrum of books.

This study attempts to analyze the major periodical indexes and catalogs of 231 titles published in Korea in the form of monographs from 1973 to 1993, in order to identify the trends of their publications and the problems in its compilation and to suggest an idea for the improvements. The results of this can be summarized as follow : 1. The publication of indexes are concentrated on some subject fields including those of social science. And there should be general indexes in the fields of the humanities and pure sciences for the researches in these fields to consult. 2. The titles of the indexes are represented by various forms. 3. The materials included are extended to all types of them including monographs, serials, these and dissertations, and newspapers, so that enhances the usefulness of the subject indexes. 4. Most of indexes are published in quarterly or yearly and seldom publish the cumulative editions. 5. Most of indexes(140 titles, 90%) are classified indexes. 6. The descriptions include basic elements of author, title, translator, contributed title, issue number, date, pages, etc, in the case of most of indexes. 7. Cross reference are seldom used, because most of indexes are classified ones. 8. Auxiliary indexes or a n.0, ppendixes are not included in 34 titles of 21%.

In tangible augmented reality (AR) environments, the user interacts with virtual objects by manipulating their physical counterparts, but he or she often encounters awkward situations in which his or her hands are occluded by the augmented virtual objects, which causes great difficulty in figuring out hand positions, and reduces both immersion and ease of interaction. To solve the problem of such hand occlusion, skin color information has been usefully exploited. In this paper, we propose an approach to simple and effective construction of a skin color map which is suitable for hand segmentation and tangible AR interaction. The basic idea used herein is to obtain hand images used in a target AR environment by simple image subtraction and to represent their color information by a convex polygonal map in the YCbCr color space. We experimentally found that the convex polygonal map is more accurate in representing skin color than a conventional rectangular map. After implementing a solution for resolving hand occlusion using the proposed skin color map construction, we showed its usefulness by applying it to virtual design evaluation of digital handheld products in a tangible AR environment.

This study explored the concept of context-aware computing and its application to the library and information services. Context-aware computing represents mobile computing techniques which gather, analyze user's contextual information and provide appropriate information services for the specific user. The idea was proposed in the late 90's but it was not widely available to the public because of the technology limitation. Recent technology development made context-aware computing possible to apply to our everyday-life information seeking using smart phone and showed the usefulness of its application. This study introduced the concept of context-aware computing with some examples of it, and finally tried to propose some of its applications to the library and information services.

Laboratory model tests were conducted to investigate the effect of surcharge loading rate on the magnitude of lateral displacement of prefabricated vertical drains (PVDs) improved deposit. The test results indicate that under the condition that the system had sufficient factor of safety (FS) ($FS{\geq}1.2$), for the similar model ground under the same total applied surcharge load, the lateral displacement increases with the increase of loading rate. The test results have been used to check the validity of a previously proposed method for predicting the maximum lateral displacement, and it shows that the data points are around the middle line of the predicted range, which supports the usefulness of the proposed method. The basic idea of the prediction method is an empirical relationship between the normalized lateral displacement (NLD) and a ration of load to the undrained shear strength of the deposit (RLS). The model test results offer some modifications of the NLD-RLS relationship: (1) instead of a bilinear relationship, NLD-RLS relationship may be entirely nonlinear; (2) the upper bound value of RLS for the proposed method can be used may be limited to 2.1 instead of the originally proposed value of 3.0.
