While academic discussions and methodological researches on oral history are being progressed in Korea, its exploitation has already begun to increase with a variety of methods and approaches in the private sector. Oral history is a new method of research, as well as another process of production of archives. In order to make valuable and highly qualified archives of oral history with the application of the aforementioned conditions and characteristics, its recognition, environment, process, and method should be improved and developed. From this point of view, it is regarded as reasonable that oral history is recognized as a part of the strategy for documentation. Oral history should be produced based on common sense and reasonable judgment, applying empirical know-how rather than logic or principles because it holds a great number of characteristics, which include variable elements in the field of oral history. In addition, its process or documentation methods should be improved and developed, giving consideration to thorough exploitation. The promotion or revitalization of oral history is a signal that announces the advent of new archives and the new subjects of history at the same time. Endeavors to produce highly efficient archives of oral history are expected to be continued with the complex accumulation of empirical assets achieved at academic discussions and its fields.

This study would suggest a measure for the improvement of the commentary program on the building concentration area of Changdeokgung Palace. In the process of the survey, the researcher attended the commentary site and tape-recorded commentaries two times. The researcher conducted an analysis of the times and contents of the tape-recorded commentaries and evaluated their appropriateness, including historicity and connectivity to the site. In addition, the researcher figured out the commentaries and the visitors' movements through drawings and field surveys and analyzed the locations and conditions of the main facilities. Through a field survey and analysis, it was found out that the commentaries included the facts and anecdotes about the buildings, the related figures and history. However, it was found out that there were very insufficient commentaries on the buildings arranged according to the commentary movements, the outside space, in particular, the traditional landscape facilities. In addition, it was found out that there are areas that would need commentaries and opening for viewing. A proposal for the improvement of the commentary program was drawn up based on the analysis. New commentary points were added, and the commentaries of the outside space of the area and the traditional landscape facilities could improve through modifying the existing commentaries. With the proposal for improvement, the time required was calculated through reading aloud at a speed the same as the existing commentary speed. Through this, it was found out that the proposal for improvement could be implemented within one hour, the same as the present commentary program. This study has a significance that it provided a measure for practical improvement that could provide the visitors with quality commentary information and more interesting experience.

This study has analyzed the effect of graph activity using CBR on the graphic ability through the observation on the 4 math-gifted 5th grade students. The study had designed the graph activity class using CBR based on the theories of graph and progressed it twice for 40 minutes, respectably. The recorded videos of the classes and the interviews of students were collected for analyzing the data, and 2 weeks later, post inspection using the same questionnaire was held for the comparative analysis on the errors that the students had made in the interpretation of the graph. According to the results of this study, the students were able to understand the flow change of the graph, interpret the relationship between variables, and contextualize the dependent variables.

This paper analyzes the distribution and classification of unrealized arguments of a predicate often called zero pronouns. in spoken Korean. Based on the transcript of a one-hour-Iong dialogue. recorded from public radio stations. I present the statistical data on argument ellipsis in Korean with respect to the frequency of zero ronouns as well as the nature of their antecedents. I go further to review some of the previous efforts to identify the discourse- theoretic functions of zero-pronouns in the framework of Centering Theory. and propose that the zero-pronouns in spoken Korean be divided into center-insensitive vs. center-sensitive classes. I also point out a couple of language-particular idiosyncrasies found in Korean, such as morpho-syntactic elements and encyclopaedic knowledge. that interact with center management in on-going discourse and often lead to difficulties in applying the centering rules and constraints to Korean.

Recently, robots technique has been developed remarkably. Emotion recognition is necessary to make an intimate robot. This paper shows the simulator and simulation result which recognize or classify emotions by learning pitch pattern. Also, because the pitch is not sufficient for recognizing emotion, we added acoustic elements. For that reason, we analyze the relation between emotion and acoustic elements. The simulator is composed of the DRNN(Dynamic Recurrent Neural Network), Feature extraction. DRNN is a learning algorithm for pitch pattern.

In this paper, we design and implement a VoIP traffic generator for simulating call processing in IP contact center systems. Creating a VoIP call based on H.323 and SIP and generating RTP traffic which uses G.711 codec, the generator lets many users simulate situations on which they call each other. With this tool, which is named VoIPTG, users can combine H.323 or SIP session control protocol, the number of users, time variation, and voice codecs and then direct various situations for simulation. This traffic generator can be used for testing functions of an IP contact center and especially it is necessary for testing the quality of IP based call recording systems.

This study analysed 8 gifted students' behavior of using calculator in the 5th grade based on qualitative data of direct proportion class with the utilization of the calculator. Pretesting with questionnaire had been made to verify students' developmental stages of proportional reasoning, and the stage was categorized according to Baxter & Junker (2001). The learning contents were made of worksheet, and the researcher held the class for 60 minutes. For analysing data, record of class was gathered to make a transcript and analysed it with Guin & Trouche' behavior of using calculator type. According to the result, each type of the behavior affected students' development of proportional reasoning differently.

In this paper, we proposed a new customized e-Ring(Enterprise Ring Back Tone) system which could be represented each user and organization feature. The e-Ring system provided the ring back tone and additional services to reduce the waiting time when the client called an organization. This system was for an appropriate organization public relations instead of the meaningless ring back tone which was used usual call, also was maximized the service availability and work efficiency which was obtained from the automatic response and service suppling to users who had needs and questions.

This paper proposed an improved 4.8kbps VSELP in order to keep the good quality in band-limited channel. In the most cases, it is difficult to keep the good quality at the low bit rate. In order to solve the problems, many methods are proposed, but they are not suitable to the Korean language structure because they are designed for being suitable to the foreign language structure. In experiment, we use the noseless Korean voice data. We show that the proposed 4.8kbps VSELP is not excellent to the 8kbps VSELP in SEGWSNR(Segmentally Weighted SNR), but it is the superior to the 8kbps VSELP in the MOS(Mean Opinion Score) test.

This study analyzed changes of representations which had come up in the problem-solving process of math-gifted 6th grade students that ACODESA had been applied. The class was designed on a ACODESA procedure that enhancing the use of varied representations, and conducted for 40minutes, 4 times over the period. The recorded videos and interviews with the students were transcribed for analysing data. According to the result of the analysis, which adopted Despina's using type of representation, there appeared types of 'adding', 'elaborating', and 'reducing'. This study found that there is need for a class design that can make personal representations into that of public through small group discussions and confirmation in the problem-solving process.
