Nagyangchun is a Dangak that has been handed down to the present time with Boheoja as a Saak of the Song Dynasty which was introduced in the Goryeo Dynasty. The title and lyrics of Nagyangchun are conveyed in the Dangakjo of Goryeosa-akji and the Jeungbomunheonbigo. The remaining scores containing Nagyangchun include Akjangyoram, Sogagwonbo Vol.4 and Vol.6 of the Joseon Dynasty and Aakbu-akbo, the 6th Aaksaeng-gyogwacheol, Leewangjikaakbu-oseonakbo during the Japanese colonial period. Besides, the current melody of Nagyangchun is based on Hangugeumak and Gugakjeonjib published by the National Gugak Center. This paper aims to examine how Nagyangchun, which is currently being performed at the National Gugak Center, went through the process of change to have the same structure and form as it is now using these scores as a research subject. The study results are summarized as follows. First, the song of Nagyangchun, which was originally Saak but transmitted as an instrumental piece without lyrics, first appeared in the Hangugeumak Vol.16 and Gugakjeonjib Vol.7 published by the National Gugak Center in 1978 and 1979. In this process, the Janggu added by Kim Ki-soo is now disappearing and is replaced by Jwago. Second, though the five notes of 黃, 太, 仲, 林, and 南 have been maintained unchanged since the Akjangyoram, the pitch of 無/應 and 夾/姑, which appear once each, gradually rises and is unified into 應 and 姑 during the period of Aaksaeng-gyogwacheol or at the latest Leewangjikaakbu-oseonakbo, and reached the present. Third, the current melody of Nagyangchun consists of a structure in which the tones and range of each phrase rises within the form of Mijeonsa (a·b·c·d) and Mihusa (e·b'·c'·d'). Particularly, except for the a-type and e-type melodies, which are the introduction for the Mijeonsa and Mihusa, the remaining melodic types show a gradually descending structure within the corresponding phrase, so the structure of ascending and descending is generally in harmony. Forth, the Ganeum that appeared from Aakbu-akbo are currently classified into seven types, and they appear in ascending pitches of 2nd, 3rd, 4th, and 5th and play a role in smoothly or fluently connecting melodic progression. Fifth, after Akjangyoram, Nagyangchun, which had been handed down as an instrumental piece without lyrics, was restored in 1960 by Lee Hye-gu, and is being passed down as the form of male and female vocals added to the instrumental accompaniment. As a result of examining the current Nagyangchun, which was formed through the process of change after Akjangyoram, it was found that there were tasks that required reconsideration of the current Nagyangchun, which is being played at the National Gugak Center, such as the arrangement of Janggu, the identification of the key, and the investigation of the lyrics. When follow-up studies are continued in the future, it will be able to contribute to the cultural transmission of Nagyangchun.

The record industry, which consists of the cultural industries, has been deeply interrelated with the innovations of the science and the technologies. In Korea, the record industry has been developed dramatically since the late 1980s, and thus it has formed a huge business, and has also brought a lot of accompanying economical effects. The record industry is constituted with four circulation steps such as producing, manufacturing, wholesaling and retailing, which follow the different locational orients, respectively. The purpose oi this study is to investigate the locational characteristics of each step. Because of the shortage of the data, this study based on the direct data from field studies, interviews, and surveys, as well as the existing document data. The results of this research are summarized as following: the record industry shows strong concentrations in Seoul and the surrounding areas. It also shows the spatial linkage with other industries that are necessary for the production, advertisement, and sales of records. The locations of the record producers are affected by the location of broadcasting stations. Therefore, they are concentrate in Kangnam and Yeouido, where many broadcasting stations are located.

Korean traditional women artists are placed in dual suffering from unequal rights in terms of gender and misrecognition endowed by historical legacy. There has been no clear cut definition but interchangeable adoption of various terms such as Yeo-ak, Yeo-gi, and Gisaeng even in the study of music theory and history itself. Study on female musician has been mostly performed on the basis of music theory and history so that one sided discourse on female traditional artist has survived and aggravated its connotation during the colonial ages and modernization. Envisioning traditional female artist as instrumentalizing their body and status as artist resulted in crucifying victims of sexual harassment is one recent example. This study is an attempt to collect knowledge on the various layers of discourse about the status and role of female traditional artist. This is a first stage of analysis covering the period Joseon dynasty where original and official records regarding female traditional artists remains until today. The findings are that policy discourse are to be classified as politico-ideological layer, music theoretical layer, and socio-political layer. It is to be clarified in the future which layer has the most sustaining influence to the present and why.

In this paper, we first looked at the structures and characteristics of the musical instrument to study the tone of haegeum, which is the only Korean musical instrument made using all the eight ingredients that make gugak instruments, and which is now the most frequently used in fusion gugak or pop music production sites. In addition, for the comparison of the various tones of the haegeum, under the same conditions, we analized how the haegeum's tone changes according to the types of Wonsan, which works as the bridge of the haegeum. Four Wonsan made of Park, Rosewood, Maple and Black Dan were used in the experiment, and low, medium, and high notes were recorded to compare the inner and outter open strings and the sound ranges. By doing so, we looked at the composition of frequency characteristics and the distribution and analyzed the timbres according to the types of Wonsan. Based on this study, it is expected to help the performers in the field choose the proper Wonsan according to each harmony part, rather than just to their tastes when performing Gugak orchestral music or haegeum ensemble. We also look forward to playing haegeum and using the timbres in various combinations of Wonsan that suit the genres at the pop music industry.

There is an agreement that sociocultural forces affect on the types of arts. There have been a little attempts to draw analogy between architecture and music. There are many objective and subjective factors for this to be true. If, however, the two arts are out of much the same social conditions, they show a degree of conformity in design and general organization. Our study shows the interrelationship between the Residential Space and structure of music. In order to clarify the interrelationship between architecture and music, the study examines ten Residential Spaces suggested by Yi-Jinkyung. The Residential Spaces are analyzed by using theory of Space Syntax. The structure of music is analyzed by tonality, counterpoint and harmony. The comparison between the Residential Spaces and music follows : From Renaissance to the 19th century, they have the same tendency to 1) openness & closure to the outer space and 2) the netting diagram in the inner space & Counterpoint 3) the tree diagram in the space & Harmony

이 논문은 사운드 합성을 위한 전용 DSP의 설계에 관한 내용이다. 설계된 음원 DSP는 사운드 카드나 전자 악기, 혹은 노래방 기기 등에서 미디 신호를 입력으로 받아서 사운드를 합성하는데 사용된다. 합성 알고리즘으로는 FM방식과 PCM방식을 지원하며, 구조 가 다르고 합성 방식이 서로 다른 8개의 알고리즘을 하드웨어적으로 구현하였다. 설계된 DSP는 44.1KHz의 16비트 출력으로 32개의 음을 동시에 낼 수 있다. DSP 내부 구조의 최 적화와 마이크로 동작의 병렬화를 통해 실제 필요한 주파수보다 낮은 주파수에서 동작시킴 으로써 전력 소모와 칩 구현에서 많은 이점을 가져올 수 있었다. 설계된 DSP는 COMPASS 툴에서 0.8㎛ 표준 셀로 합성되어 칩으로 제작되었으며, 동작 주파수는 33MHz이다. 제작된 칩을 검증하기 위해 PC에 삽입되는 음원 모듈 카드를 제작하여 미디 음악을 연주시켜 보았 다. 그 결과 원하는 동작 주파수에서 완벽하게 사운드를 합성해내는 것을 확인할 수 있었다.

Android는 스마트폰 시스템에서 사용되는 소프트웨어 플랫폼으로 JVM(Java Virtual Machine)을 기반으로 한다. JVM은 실시간성 지원을 고려하지 않은 기술이며 이를 기반으로 한 Android 또한 실시간성을 지원하기 위한 어떠한 방법도 가지고 있지 않다. 스마트폰 시스템을 통해 QoS를 보장하면서 멀티미디어 서비스를 제공하기 위해서는 JVM 기반의 시스템을 위한 실시간성 향상 기술이 필요하다. 본 연구에서는 기존의 안드로이드 시스템에 리눅스에서 제공하는 실시간 보장기능을 적용할 수 있도록 지원하는 크로스 레이어 구조를 제안한다. 이 구조를 통해 우리는 리눅스 커널에 존재하는 실시간 스케줄러를 사용하여 태스크가 실시간으로 실행될 수 있도록 지원한다. 또한 다양한 목적을 가진 어플리케이션이 공존하는 스마트폰 시스템에서 실시간성을 요구하는 어플리케이션에 대해 차별적으로 실시간성을 보장할 수 있다. 소프트 리얼타임 특성을 가지는 멀티미디어 태스크를 실시간 태스크로 실행하고 실제 스마트폰에서 실행시켰을 때 시스템에 높은 부하가 걸릴 때에도 합리적인 실시간 보장성을 얻을 수 있다. 음악을 재생한 실험에서는 1200개의 프로세스가 백그라운드 태스크로 실행되는 상황에서도 끊김을 느낄 수 없을 정도로 QoS를 보장성이 높은것을 확인 하였다. 본 연구에서 제안하는 실시간성 지원을 위한 크로스 레이어를 통해 스마트폰은 낮은 비용으로 기존의 어플리케이션을 변경하지 않으면서 실시간 특성을 지원할 수 있다.

In this paper, we propose an efficient method to describe and save Jeongganbo score which has various structures and symbols by using XML (Extensible Markup Language). To do this, analysis of Jeongganbo's structures, and classification of symbols for jeongganbo were preformed. Then, Jeongganbo DTD (Document Type Definition) was defined to describe Jeongganbo score in XML document. To verify the proposed method, we produced a Jeongganbo score XML file for real Jeongganbo score according to the proposed Jeongganbo DTD, and then evaluated the produced XML file by using Jeongganbo XML interpreter software which can interpret the Jeongganbo XML file and represent the Jeongganbo score.
