There have been studies reporting the increase in student confidence in mathematics when using technology. However, past studies indicating a positive correlation between technology and confidence in mathematics do not explain why they see this positive outcome. With increased availability and easy access to the Internet in schools and the development of free online virtual manipulatives, this research was interested in how the use of virtual manipulatives in mathematics can affect students confidence in their mathematical abilities. Our hypothesis was that the classes using virtual manipulatives which allows students to connecting dynamic visual image with abstract symbols will help students gain a deeper conceptual understanding of math concept thus increasing their confidence and ability in mathematics. The participants in this study were 46 fifth-grade students in three ability groups: one high, one middle and one low. During a two-week unit on fractions, students in three groups interacted with several virtual manipulative applets in a computer lab. Data sources in the project included a pre and posttest of students mathematics content knowledge, Confidence in Learning Mathematics Scale, field notes and student interviews, and classroom videotapes. Our aim was to find evidence for increased level of confidence in mathematics as students strengthened their understanding of fraction concepts. Results from the achievement score indicated an overall main effect showing significant improvement for all ability groups following the treatment and an increase in the confidence level from the preassessment of the Confidence in Learning Mathematics Scale in the middle and high ability groups. An interesting finding was that the confidence level for the low ability group students who had the highest confidence level in the beginning did not change much in the final confidence scale assessment. In the middle and high ability groups, the confidence level did increase according to the improvement of the contest posttest. Through interviews, students expressed how the virtual manipulatives assisted their understanding by verifying their answers as they worked and facilitated their ability to figure out math concept in their mind and visually.

In electronic catalogs, each item is represented as an independent unit while the parts of the item can be composed of a higher level of functionality. Thus, the search for this kind of product database is limited to the retrieval of most similar standard commodities. However, many industrial products need to configure optional parts to fulfill the required specifications. Since there are many paths in finding the required specifications, we need to develop a search system via the configuration process. In this system, we adopt a two-phased approach. The first phase finds the most similar template, and the second phase adjusts the template specifications toward the required set of specifications by the Constraint and Rule Satisfaction Problem approach. There is no guarantee that the most similar template can find the most desirable configuration. The search system needs backtracking capability, so the search can stop at a satisfied local optimal satisfaction. This framework is applied to the configuration of computers and peripherals. Template-based reasoning is basically the same as case-based reasoning. The required set of specifications is represented by a list of criteria, and matched with the product specifications to find the closest ones. To measure the distance, we develop a thesaurus of values, which can identify the meaning of numbers, symbols, and words. With this configuration, the performance of the search by configuration algorithm is evaluated in terms of feasibility and admissibility.

The late $19^{th}$ and early $20^{th}$ centuries of Korea were the times when the Confucianism (牲理學) ideology was shaken heavily under the influences of modernism and capitalism by Western and Japanese military and political-economic forces. Under such circumstances, alteration of clothing was much influenced by ideologies than changes in social structure or technological advance. In this study, an ideology was defined as "the force which drives people into a particular social order". Ideologies were postulated as an ongoing process of socialization with dialectic features rather than being a static state. Comparative analyses on conflict structures and different clothing patterns symbolizing the ideologies of the Ruling (支配) and the Opposition (對抗) were conducted. Investigating dresses as representations of ideologies is to reconsider the notion of dichotomous confrontation between the conservatives (守舊派) and the progressives (開化派) and a recognition of Koreans' passively accepting modernity during the Japanese occupation. This may also have contributed to enlightening Koreans about modernization. Here are the results. First, the theoretical review found that ideologies were represented by not only symbols of discourse, but also dresses, and that dresses embodied both physical and conceptual systems presenting differences between ideologies and their natures, Second, during the late 19th century Korea, conflict between conservatives' Hanbok (韓服) and progressives' Western suits (洋服) was found. Moderate progressives showed their identity by "Colored Clothing" (深色衣), and radical progressives by black suits with short hair (黑衣斷髮) or by western suits (洋服). The ultimate goal of both parties was a "Modern Nation". With these efforts, pale jade green coats and traditional hats symbolizing the nobleman class was eliminated within 30 years from 1880 to 1910, and then simple robes and short hair emerged. However, the powerful Japanese army had taken over the hegemony of East Asia, and Korea was sharply divided into modernization and pro-Japanese camps. Third, during the time of Japanese colonial rule, the dress codes having set by the modernization policies during the time of enlightenment were abandoned and colonial uniforms for the colonial system was meticulously introduced. During this period, Western or Japanese-style uniforms were the symbol of the ruling ideology. In the mean time, Hanbok, particularly "White Clothing (白衣)", emerged as a representation of the opposition ideology. However, due to Japan's coercive power and strong zeal for "Great orient (大東亞)", white clothing remained as a mere symbol. Meanwhile, Reformists (實力養成論者) movement toward improving quality of life followed a similar path of the Japanese policies and was eventually incorporated into the ruling ideology. Fourth, dresses as representations of ruling ideologies were enforced by organizational powers, such as organizations and laws, and binding policies, and changes in such dresses were more significant when the ruling ideologies were stronger. Clothing of the opposition ideology was expressed as an aggregation of public consciousness. During the period, the subjects of ruling ideology and the objects who were granted modernization benefits were different although their drives for colored clothing with short hair (色衣斷髮) for modernization were similar.

This paper is the study on the Medium Designator in Non-book materials. Main contents of this study were as follows; 1. The medium designator serves to indicate the class of material to which an item belongs. This is used to give an 'early warning' ;to the catalogue user. 2. This medium designator may be further divided into two elements ; a general material designation (GMD), for example video-recording, and a specific material designation (SMD), for example, videodisc. 3. GMD: In cataloging, a term indicating the broad class of material to which a bibliographic item belongs, such as 'motion picture', and SMD : In descriptive cataloging, a term indicating the special class of material (usually the class of physical object) to which a biblographic item belongs, such as videocassette. 4. Locating the medium designator after the title proper was not prescribed until ISBD(G) and AACR2. In pre-ISBD(G) codes, the ,early, warning type of medium designator was placed after all title information. But in AACR2, the medium designator is placed after the title proper, but before parellel title and other title information. 5. In Terminology, Two separate lists of designations are given in AACR2, l.1C1, one for British and one for North American use. The British list contains fewer terms, and uses generic categories to group together some of the North American list. 6. The problem of where to place the medium designator might be circumvented by using some kind of early alerting device other than a formal element of biblliographic description. Various alternatives have been suggested. A more popular device is the provision of symbols or 'media code' which are part of the call number and indicate the porticular medium type. 'Colour-coding' the use of used by some libraries but is now longly discouraged. 7. According to Frost. The medium designatorhas been generally reeognized as serving three functions; 1) as a statement of the nature or basic format of the item cataloged and thus as a meant of informing the user as to the type of material at hand; 2) as a description of the physical charaetistics of medium and as a means of alerting the user to equipment needed to make use of the item. 3) as a device to distinguish different physical formats which share the same title. 8. AACR2 raises some problems which decision makers have neet had to face preriously It provides a GMD for every item in the collection including books and it makes the application of any or all GMD's optional.

The purpose of this study was to extract of Sub-elements of technological communication skills and to construct of a system model. In order to achieve the goal of the study, it was carried out in two steps: (1)Extraction sub-elements and definitions of technological communication skills, (2)Development of a system model of technological communication skills. Obtained conclusions by the process of this research were as follows. First, sub-elements of the technological communication skills were extracted and they were images, sketches, flowcharts, drawings, prototyping, symbols tables graphs and presentations. Second, using the 'technological communication tools' based on the "collaborative activities in online and offline', technological communication skills were defined as communication skills to be raised through the process of 'Idea through the Communication', 'Realization through the Communication', 'Wrap up through the Communication'. Third, technological communication skills were described as the system, in which 'Idea through the Communication(images, sketches, flowcharts)', 'Realization through the Communication(design, prototyping)', 'Wrap up through the Communication(symbol table graph, presentation)' were collaboratively activated. Fourth, checking tool for the technological communication skills was developed, based on checking tool for the existing communication skills and system model for technological communication skills. And it was improved by the expert validity test.

In the midst of the fusion era in digital contents, securing a variety of traditional cultural sources is important. Out of its long history, Korea has extensive spectrum of cultural contents in combination with conventional religions. Buddhist art has been a pillar of the traditional culture for a long time in Korea, by which we could secure new sources for cultural contents and classify them. This is aimed that we could bring the future brands into reality based on the traditional culture through Buddhist cultural contents. This study hired the original cultural forms in the viewpoints of traditional culture. Study on the implication through the symbols of Avalokitesvara (觀音菩薩) and Buddhist child (童子) in Buddhist art might allow to secure a foothold to create own characters. Thus, focusing on Avalokitesvara (觀音菩薩) and Buddhist child (童子) in the Buddhist sacred images as registered in Cultural Heritage Administration for national treasures, those traditional characters were reviewed through their own system of symbol. During the course, Buddhist characters were available to be classified into DB by their roles and materials지물. This study could help to exploit the complicated Buddhist culture of its symbolic meanings and to shape them into original forms of the culture. Also, through the meanings of the Buddhist sacred images, it could provide the digital contents pool with Korean traditional characters.

Paper currency is a cultural symbol sign representing identity of a nation as well as a tool of barter system and a measure of value. The purpose of this study is to analyze the design characteristics shown in the pattern of the paper currencies of advanced countries and Korea and to make comparative analysis of the image type of each nation as a cultural code. The results show that 1) the usability of paper currency design was evaluated by denominations, size type, color, braille system and the paper currencies of Switzerland and EU were judged superior to those of the other counties. 2) The national image type represented paper currencies was classified as 'state oriented type' and 'culture & art oriented type'. The countries of Korea, U.S.A, Japan etc. have on the paper currencies the ruling class who contributed to organizing the national system foundation emphasizing their nationalism. In the case of European countries, their paper currencies reveal a variety of citizen who have contributed to art, science, music, architecture without distinction of gender and this fact puts an emphasis on egalitarianism and equality of both senders and importance or cultural art. 3) Paper currency design of Switzerland, Netherlands, France, U.K. was visualized as an art work with utilization of work-type subject, brilliant color, CG technique, unique layout etc. This study provides us with a valuable opportunity to examine the present state of the Korean paper currencies design in Comparison With those of the world's advanced countries. It is expected that this study could be a resource material for new paper currency design and emphasize the importance of the paper currencies representing a national image as a cultural design.

This study identifies the symbolism of cross symptoms of different classes during the modernization process based on the imagery of and , both of which are Korean films made in the same era of the 1960s. The study referred to a number of Korean family movie films in the 1960s, in particular and , which are notably different in ways of expression and in social class of the subject matter, and identifies how the films express the mixed aspects of the cross modernization period. The film uses a grotesque expressionist method to voyeuristically look into a newly emerging middle class family, and the deconstructive aspect of a family unit whose excessive desire leads to its own ruin; thus, the film presents a new perspective into the various social issues that emerge in the near future. In contrast, engages realistic depictions to describe in detail the deep conflict of pain and hope within the hardships of life from the urban poor through a deep family conflict. Ultimately, the two films expose the various social issues through the familiar and the unfamiliar that appear from the mixed aspects of the cross modernization period, in other words, the conflicting images of the traditional and the modern.

Natural language processing (NLP) is an emerging research area in which we study how machines can be used to perceive and alter the text written in natural languages. We can perform different tasks on natural languages by analyzing them through various annotational tasks like parsing, chunking, part-of-speech tagging and lexical analysis etc. These annotational tasks depend on morphological structure of a particular natural language. The focus of this work is part-of-speech tagging (POS tagging) on Hindi language. Part-of-speech tagging also known as grammatical tagging is a process of assigning different grammatical categories to each word of a given text. These grammatical categories can be noun, verb, time, date, number etc. Hindi is the most widely used and official language of India. It is also among the top five most spoken languages of the world. For English and other languages, a diverse range of POS taggers are available, but these POS taggers can not be applied on the Hindi language as Hindi is one of the most morphologically rich language. Furthermore there is a significant difference between the morphological structures of these languages. Thus in this work, a POS tagger system is presented for the Hindi language. For Hindi POS tagging a hybrid approach is presented in this paper which combines "Probability-based and Rule-based" approaches. For known word tagging a Unigram model of probability class is used, whereas for tagging unknown words various lexical and contextual features are used. Various finite state machine automata are constructed for demonstrating different rules and then regular expressions are used to implement these rules. A tagset is also prepared for this task, which contains 29 standard part-of-speech tags. The tagset also includes two unique tags, i.e., date tag and time tag. These date and time tags support all possible formats. Regular expressions are used to implement all pattern based tags like time, date, number and special symbols. The aim of the presented approach is to increase the correctness of an automatic Hindi POS tagging while bounding the requirement of a large human-made corpus. This hybrid approach uses a probability-based model to increase automatic tagging and a rule-based model to bound the requirement of an already trained corpus. This approach is based on very small labeled training set (around 9,000 words) and yields 96.54% of best precision and 95.08% of average precision. The approach also yields best accuracy of 91.39% and an average accuracy of 88.15%.

Today's sports, by themselves, express a wide variety of phenomena and reproduce or imply complex social symbols. The definition of sports being transformed in combination with ideology, which has become a central issue in each era, has become more diverse in recent years. Recently, with the 4th Industrial Revolution leading the social phenomenon, sports culture is producing a new phenomenon. In this era, we need the study in the question of how to understand and interpret sports culture is the right approach. The struggle for survival in each discipline was expressed as a reinterpretation of sports culture. This is to answer questions about how sports culture is consumed, spread and reinterpreted. The purpose of this study is to find out the direction and directing point of sports culture. Based on such problem recognition, five types of answers to what sports culture consumes were presented. Based on this, the fairness related to school sports, sports society-club(sports clubs), sports events, sports media, and sports was suggested as a medium for the spread of sports culture. We are accepting and transforming numerous scientific civilizations to improve sports culture and to promote consumers. However, there is a pity not to define such a thing. Efforts at a more fundamental level, such as cultural regulation and fundamental directions, need to be discussed. The framework of reinterpretation of sports culture should be constantly looking for directions and answers about what to do, not just the level of interpretation.
