This study is to find the methods that BIBFRAME could accept the new concept of representative expression in the RDA Toolkit Beta which has developed in 2019. Research methods were the literature reviews and the mapping between RDA Toolkit Beta and BIBFRAME. BIBFRAME's acceptance of representative expression of RDA Toolkit Beta was suggested as followings. First, the properties of representative expression should be defined in BIBFRAME because the RDA Toolkit Beta defined the expression attributes and representative expression elements apart. Three choices for BIBFRAME's acceptances are (1) to develop the newly devised representative expression properties (2) to specify representative expression properties with using refinement (3) to differentiate representative expression properties with using class. Second, as relationship elements should be defined in BIBFRAME to link work and representative expression which transfer the expression attribute to work. This study will contribute to revise the BIBFRAME because this focusd on BIBFRAME's acceptance of RDA Toolkit Beta in which reflected LRM.

This study is to investigate the increasing membership rate against the previous year among the members registered as representative members and general members of the Korea Dental Technician Association from 1990 to 2004. With this study, we aim to provide more systematic data about the current status of each members in the KDTA and reconsider the needs for the practical and distinguishing management of the members. Results of the study are as follows; 1. The increasing rate from 1990 to 2004: whole members; 2.14, representative members; 2.22, general members; 2.11. Average of increasing rate against the previous year: general members; 6.10%, whole members; 5.94%, representative members; 5.91%. 2. The increasing rate in the city branch from 1990 to 2004: whole members; 2.12, representative members; 2.03, general members; 2.15. Average of increasing rate against the previous year: general members; 6.63%, whole members; 6.05%, representative members; 5.23%. 3. The increasing rate in the province branch from 1990 to 2004: whole members; 2.21, representative members; 2.74, general members; 2.01. Average of increasing rate against the previous year: representative members; 7.58%, whole members; 5.99%, whole members; 5.35%. 4. Mean ratio between representative members and general members from 1990 to 2004: 1:2.6 against the whole members, 1:2.8 in the city branch, 1:2.3 in the province branch. The ratio between representative members and general members in the year 2004: 1:3.1 in Kyoungnam province, 1:3.0 in Inchon, 1:2.9 in Kwangju that indicates a high ratio between two members and in the case of Chongbuk, the ratio between two members is rather low as shown in 1:1.1.

This study is an analysis on the focus of textbooks regarding the statistical chapters of "measures of representative(central tendency) and of the spread". Applying the summary-concept criteria of Juhyeon Nam(2007), 4 kinds of aspect of the chapter; (1) definition and its teleological validity of the measures of representative, (2) definition and practical value of the measures of spread (3) distributional form on the measures of representative and of spread (4) location and scale preservation or invariance of the measures of representative and of spread were observed. On the measures of representative, some definitions were insufficient to check the teleological validity of the measure. Most definitions of the measure of spread were based on the practical view points but no preparation for the future statistical inferences were found even by implication. Some books mention about the measures of representative and of spread for distributions, but we could not find any comments on the correspondence between the sample mean and the expectation of a distribution or population mean. However it is stimulant that some books check the validity of corresponding measures with the location and scale preservation or invariant property, that were not found in the previous curriculum.

Recently, we extract the representative melody of the music and index the music to reduce searching time at the content-based music retrieval system. The existing study has used MIDI data to extract a representative melody but it has a weak point that can use only MIDI data. Therefore, this paper proposes a representative melody retrieval method that can be use at all audio file format and uses digital signal processing. First, we use Fast Fourier Transform (FFT) and find the tempo and node for the representative melody retrieval. And we measure the frequency of high value that appears from PCM Data of each node. The point which the high value is gathering most is the starting point of a representative melody and an eight node from the starting point is a representative melody section of the audio data. To verity the performance of the method, we chose a thousand of the song and did the experiment to extract a representative melody from the song. In result, the accuracy of the extractive representative melody was 79.5% among the 737 songs which was found tempo.

The purpose of this study is to analyze the effect of average unit learning on the knowledge of the representative value of 5th grade elementary school students. In the information-oriented society, the ability to organize and summarize the data has become an essential resource. In the process of correctly analyzing statistical data and making reasonable decisions, the summary of the data plays an important role, and it is necessary to learn the concept of representative values in order to describe the center of the data in a series of numbers. For research, an informal knowledge type possessed by a fifth grade elementary school student with respect to a representative value before learning an average unit is examined and compared with the representative value after learning the average unit. A suggestion point for representative value guidance in school mathematics is provided while examining the change in knowledge with respect to the representative value. Seeing the informal types of elementary school students' representative values will help them learn how to formalize the concept of representative values in middle and high schools. It will give suggestions about the concept of representative values and the method of instruction that should be dealt with in elementary schools. The informal knowledge about the representative value can help with formal representative value that will be learned later. Therefore, This study's discussions on statistical learning of elementary school students are expected to present meaningful implications for statistical education.

Objectives : The purpose of this study is to develop the method of selecting representative pulse wave. Methods : The pulse waves were acquired at the right and the left Guan point(關部) with 1420 people who were apparently healthy. The shape agreement of right and left pulse wave and the floating-sinking ratio were compared with three cases, which were the pulse height based method, the pulse area based method, and the pulse time based method. Results : In the point of the shape accordance, the pulse time based method was the best, and the pulse area based method was the worst. In the point of the floating-sinking ratio, the pulse height based method was the worst, and the pulse time based method was the best. Conclusions : So, the pulse time based method was recommended for selecting the representative pulse wave. This study compared the selection methods of representative pulse using the physiological characteristics of pulse wave. Further studies are required, because the representative pulse wave is the main factor of determining the shape and the floating-sinking characteristic of the pulse wave.

Purpose: In Seongnam City, a number of festivals are held in various areas, led by the city and private organizations. The necessity of developing a representative festival of Seongnam City, which can enhance the brand value of Seongnam, a cultural city, and promote a sense of local community and economic effects, is emerging. The purpose of this study is to analyze festival-related ordinances of Gyeonggi-do local governments, and to derive implications necessary for the development of festival support ordinances representing Seongnam City. Research design, data, and methodology: This study used the database of National Legal Information Center of the Ministry of Legislation and the autonomous legal information system to thoroughly investigate the ordinances related to festival support of basic local governments in Gyeonggi-do and the whole country. To do this, descriptive statistics analysis was conducted. Results: As a result of the study, it was found that 168 organizations (68.6%) of 245 local governments nationwide have adopted the festival support ordinance, and there are a total of 231 ordinances. In the case of basic organizations, out of 228 basic organizations, 151 organizations, including Seongnam City, adopted the ordinance on festival support, showing an adoption rate of about 66%. As a result of analyzing the basic organizations that enacted representative festival related ordinances among Gyeonggi-do basic organizations, 9 out of 28 cities adopted 16 representative festival ordinances, based on the legal and institutional basis for supporting representative festivals. Conclusions: In the case of Seongnam City, it is believed that in order to develop a representative festival, an ordinance to support the representative festival must be established. Considerations regarding the composition of the ordinance for the representative festival were discussed.
