In this paper, a new stereo image watermarking scheme based-on adaptive disparity estimation algorithm is proposed. That is, a watermark image is embedded into the right image of a stereo image pair by using the DWT and disparity information is extracted from this watermarked right image and the left image. And then, both of this extracted disparity information and the left image are transmitted to the recipient through the communication channel. At the receiver, the watermarked right image is reconstructed from the received left image and disparity information through an adaptive matching algorithm. a watermark image is finally extracted from this reconstructed right image. From some experiments using CCETT's 'Manege' and 'Friends' images as a stereo image and English alphabet '3DRC' as a watermark image, it is found that the PSNRs of the watermarked image from the reconstructed right images through the adaptive matching algorithm & DWT is improved 2.03 dB, 3.03 dB and robusted against various attacks. These experimental results also suggest a possibility of practical implementation of an adaptive matching also-rithm-based stereo imagewatermarking scheme proposed in this paper.

The purpose of this research is to compare the opinions of three different groups - subject specialist librarians(group I) . students of department programs(group II) and students of college programs(group III) - as to whether these groups have a different way of thinking from each other concerning a general culture for subject specialist librarianship. Questionnaire are carried out for this research and the responses analyzed to draw a conclusion. Major findings are as follows: 1) The subject specialist librarianship to be important to all three groups and a desirable academic career of group I shows a tendency to have both B.A. degree in the subjet field and M.A. degree in library & information science, $15.3\%$ of group II and $82.9\%$ of group III appear to be belonging to either minor or double major programs, 2) the 37-45 major credits to be ideal to group I & III, and 46-55 group II, 3) a knowledge in 'Computer' and 'English' is mostly demanded to all three groups as the general culture for subject apecialist librarianship, 4) theoretical courses to be very important to group I and technical courses to group II & III, 5) the collection and access of library materials to be regarded to all three groups as an important role for future librarians.

The Mongolian ger is ideally suited to the mongol's steppe climate and the nomadic way of life. This is a multipurpose dwelling which can be easily collapsed, transported to another place and put up again fully preserving its original shape. The pastoral nomadic ger has two key components: the wooden framework and the felt cover. The wooden parts are the walls(khana), the long poles(un), the smoke escape(toono) and its supports(bagana). One wall consists of 10-15 branches of willow tree. each about 1.5m high bound together in a way making it possible to fold it for transportation and then unfold it like an accordion. The unfolded walls are connected to form a circle. The long poles(un) are fastened to the upper part of the walls, with the other end passed through the toono hole, the only sky window and smoke escape through it from the ger. The toono is propped up by two posts, called bagana. All this forms the wooden framework of the ger, which is covered with felt. When the herders fire up their metal stoves, the temperature inside the ger becomes quite comfortable. Because the nomads live in a climate where there is only one growing season in a year, they do not make long migrations to new pastures. Livestock subsist on standing vegetation for eight months of the year. The basic pasture migration strategy is to leave enough standing vegetation at the end of the growing season in September to suffice until the new growth appears the following May. Mongolians use a type of compressed tea leaf that is called "brick" tea in English because it is rock solid and roughly the shape of a brick. And they consume a larger percent(88%) of fat from animal products such as meat, milk, butter, and cheese than any other people in the world. Milk products made from the milk of sheep, yak, and goats are major foods in the nomad's diet, but they are produced mainly in summer when all the animals are lactating. Mongolians made their special nomadic food culture on the steppe.

In today's increasingly data-intensive academic environment, data is becoming the foundation of academic communication as a research outcome rather than a research by-product. However, there is a limit to guaranteeing actual data reuse only by expanding the data supply or securing accessibility. In order to overcome this, it is necessary to understand the data reuse behavior and data needs in-depth. Therefore, this study attempted to identify the major data reuse behavior and data needs among researchers. To this end, the authors of KCI papers among the data reuse documents of the Korea Social Science Data Archive (KOSSDA) for the past 3 years were targeted. An in-depth interview was conducted with 12 researchers who accepted the interview. As a result, factors considered when reusing data were personal, economic, technical, and social aspects, and it was found that the data itself was used or contextual information of the data was used depending on the purpose of data reuse. The path to acquiring data is a web-based source of information, and a path through informal communication can also be found. In terms of the data needs, it was found that they prefer English, the United States, and institutional producers. Also they have a clear preference for quantitative data from an interviewer-filled interpersonal interview survey method, rich metadata along with raw data, and data that contains identification information. However, due to the lack of confidence in the value, it is negative for the use of data with controlled access and use, and it is difficult to confirm a clear preference because there is no similar data available for selection in terms of size and freshness.

Idol music, which began to gain huge popularity in the domestic music market in the mid-1990s, has become one of the major global contents thanks to the global popularity of K-POP. As a result, the Korean music market continues to grow, forming the world's sixth-largest music market, and domestic music agencies are focusing more on fostering idol groups and producing idol music. The global success of idol music is surprising, but this has resulted in the domestic music market being biased toward idol music. As a result of the study, it was confirmed that there are several problems with the phenomenon of being biased toward similar types of musicians and music content. First, just as trend-oriented cultural contents face the problem of life expectancy all the time, the "Korean Wave" is also forced to think in terms of identity and sustainability. Second, it was observed that only consumers of a certain age may cause cultural alienation of other age groups, and thirdly, various problems such as shrinking creative paths due to the size of the cost required for idol group production and the lifespan of idol musicians' art activities. This paper derives the reality of the domestic idol bias phenomenon through comparative analysis of the English-American music market and the domestic music market, which have had a profound influence on the global music market in popular music history, and verified the theory and results through an expert survey using the Likert scale. In addition, the problems caused by the idol bias phenomenon were considered based on the theory of cultural diversity, and improvement directions were also suggested to solve this problem.

The college of education should support pre-service teachers to learn knowledge of their major and develop the ability of presenting or teaching the knowledge. The pre-service teachers may have many opportunities of presentations to develop the ability of teaching. Some college of education provide such opportunities in the 'seminar' course. In this study we investigated the pre-service teachers' perceptions on the seminar where they present contents of their major, developed the framework to analyze and evaluated the seminar presentation ability, and explored the change of presentation ability through a case study. Pre-service teachers perceived that from the seminar they could develop the presentation skill and understand the scientific contents more deeply. However they pointed out the difficulty of understanding others' presentations, discussing on the contents and interpreting the English paper. We developed the presentation analysis framework including the evaluation elements, the evaluation items, and the evaluation methods according to the progress of a seminar presentation. Using this framework we evaluated and compared the development of seminar presentation ability of a per-service teacher both quantitatively and qualitatively. We discussed the educational implication of this study such as the suggestion for the effective management of a seminar and the usage of the presentation analysis framework.

Objectives: The purpose of the study was to examine the expected role and competency of future public health dental hygienist. Methods: This study was cross-sectional design. One dental hygienist per 16 cities and provinces was selected from the list of Korea Society of public dental hygienists. After signing in the informed consent, the interview was carried out. Transcripts were made after each interview. Six researchers recorded meaningful contents in the transcripts. They classified and integrated the information that they had recorded commonly or not. Their opinions were converged by conference. Two supervisors verified results whether they were derived from actual recordings for the reliability of the results. The records were confirmed once again and corrected into common message. Results: The main difficult subjects in public health official examination were public health, English, and medical legislation to pass the examine. The preliminary certificates included public health related certificate, computer certificate, and driver's license. In the personality aspect, creativity, activeness, cooperation and good responsibility were very important trait to public health official. Among 16 interviews, 9 were positive and 5 were negative about the future prospects of a public dental hygienist. Conclusions: The future of public health dental hygienist will be positive. Throughout effort to prepare for the public health official, the public health dental hygienist will be expanded and in many ways the dental hygienists will take the charge of the important parts of the public health administration in the near future.

By understanding physiological characters of plants and the environment, plant design should decide the relationship with other plants from the designer's curiosity of the plant's color, texture, form and other aspects. There are a traditional tendency that many designers put the plant's color ahead of other aspects. This study explores 4 gardens of Gertrude Jekyll's Munstead Wood, Vita Sackvill-West's Sissinghurst, Christopher Lloyd's Grest Dixter and Lawrence Johnston's Hidcote Manner. The flower border of Munstead is started with light grey and blue at the edge and it gets stronger colors like red and orange as the line comes to the middle. It is noticeable that white an blue colors were used unlike before. Sissinghurst made use of purple color which was very seldom used before and Dixter added orange to magenta color that was already there, giving a strong visual effect and through juxtaposition it could realize the wanted effect. A strong red border line was created in Hidcote Manner. Above mentioned designers arranged various colors so that visitors can experience different spacial senses according to observer's direction. In the cognitive space the main color and the secondary color arranged leading to the fact that the observer recognizes it as a whole. In plant design time means seasonal performance which influences the main color arrangement like gradation or contrast. Moreover, space determines the color's zone when it comes to plant design.

This study is the most important component in establishing the court library as the best legal library in Korea responsible for professional legal services. A perception survey was conducted on the target. As a result, first, looking at the collection direction based on the needs of general users, in the case of collection types, preference in the order of books, electronic materials, and non-books should be considered. It seems to be necessary to plan a collection development policy reflecting the high preference for books. In addition, in the non-books section, the preference for non-book materials in the form of video rather than audio is much higher, and in the case of language, domestic books should be collected mainly. Second, looking at the collection direction based on the needs of experts, the satisfaction of experts is generally low, so it seems that a collection development policy should be established to improve this. As for the type of information source, preference was shown in the order of electronic materials, books, and non-books. There is a need. The future collection direction should be based on the preference shown in the order of procedural law, specialized field, basic substantive law, and legal series. Also, when collecting the same book, electronic form of legal data should be considered rather than printed. In addition, it is necessary to collect collections mainly from domestic books, and then, it is expected that the scope of collection should be expanded to prioritize English and American books, Japanese books, and German books.

A wh-phrase positioned in an embedded clause can be interpreted as having a matrix scope if the sentence is produced with proper prosodic structures such as the wh-intonation. In a previous experiment, a sentence with a wh-phrase in an embedded clause was given to 40 speakers of Gyeongsang Korean. A script containing the sentence was provided to induce a matrix scope interpretation for the wh-phrase. These 40 utterances were prepared as stimuli for a perception test to verify whether the wh-phrases in the stimuli were perceived as having matrix scopes. Each utterance was played thrice to 24 subjects. The results showed that more than half of the 72 responses indicated a preference for an embedded scope rather than a matrix scope in 20 of the utterances. A multiple linear regression analysis showed that the matrix scope responses were best predicted by the magnitude of the pitch prominence in a prosodic word consisting of an embedded verb and a complementizer. The pitch prominence was calculated by subtracting the fundamental frequency (F0) at the right edge of the prosodic word from the peak F0 in the same prosodic word. The smaller the magnitude, the more matrix responses there were. These results suggest that the categorical perception of wh-scopes is based on the magnitude of pitch prominence.
