We developed an electronic music glove (EMG) system that could play musical scores in real time processing. The EMG system interfaces with the signal coming from the controller to the sound card in the computer. The computer, according to the status of the finger and foot switches, generates the signals to the speaker systems using the application C++ program by making use of MIDI message. The EMG systems can control up to several octave notes and duration of sound, and several musical performance expressions such as chorus, reverberation, rhythm, and volume. Finally, our EMG could play the performance of simple music depending on the choice of any kind of musical instruments in the sound card in computer systems.

This study is about the way of music composition which is based on S/W system and also shows the skill of moving image edit for using the composed music. The result of this contents informs the mixture of a composed music by the Midi program and a moving image for using by the S/W system, also guides many students that the Computer Music Composition and Image Edit is not a difficult sphere. It is not only a main subject but also a main goal of this study.

Continuing advance in computers and MIDI devices has accelerated research on the computerized music technology, Realization of high speed computer communication networks facilitated on-line computer music systems, which needs to send a volume of multimedia data. This paper presents the design and implementation of the Remote Concert Education System which helps users practice ensemble without gathering in a room. The system maintains the music database, identifies tones and measures of the melody played with different instruments, check the correctness on-line, and finally provides the analysed results of the ensemble. The developed system can be used as a supporting system for music education if high speed communication network is available.

To evaluate the correlations of microbial populations with soil healthiness and crop production and establish the criteria for microbial population of soil types. We analyzed the microbial community structure of 13 soils which were different in physical and chemical properties and cultivation methods. According to the analysis of microbial population suing the dilution plate method, the large differences of the microbial population structures among soil types were shown: aerobic bacteria $2-27{\times}10^6$, fluorescent Pseudomonas $1-1,364{\times}10^5$, Gram negative bacteria $1-126{\times}10^4$, and mesophilic Bacillus $1-110{\times}10^5$. The density of Gram negative bacteria was highest on red pepper cultivating soils (sample no. 4 and 6) of Umsung and Gesan, Chungbuk, and the density of the fluorescent Pseudomonas was highest on greenhouse soil (sample no. 7) of Jinju, Kyungnam. The crop productivity of three soils was high as compared with those of other soils. It was supposed that the density of fluorescent Pseudomonas and mesophilic Bacillus were correlated with the incresed crop production. By MIDI analysis, 579 strains isolated from 13 soils composed of a variety of microbes including 102 isolates of Agrobacterium, 112 isolates of Bacillus, 32 isolates of Pseudomonas, 44 isolates of Kocuria, and 34 isolates of Pseudomonas. Among the 624 isolates of Gram negative bacteria, Pseudomonas including P. putida and p. fluorescens occupied the highest density (51%), and Stenotrophomonas maltophilia and Burkholderia cepacia also appeared at high density. From RAPD analysis, the fluorescent Pseudomonas strains isolated from 13 soil types showed a high level of strain diversities and were grouped into 2 - 14 patterns according to soil types. Many of unknown bacteria were recovered from the paddy soil, and needed to be further characterized on the molecular basis.

In this paper, we propose a smart system that can optically recognize a music score within a document and can play the music after recognition. Many historic handwritten documents have now been digitalized. Converting images of a music score within documents into digital files is particularly difficult and requires considerable resources because a music score consists of a 2D structure with both staff lines and symbols. The proposed system takes an input image using a mobile device equipped with a camera module, and the image is optimized via preprocessing. Binarization, music sheet correction, staff line recognition, vertical line detection, note recognition, and symbol recognition processing are then applied, and a music file is generated in an XML format. The Music XML file is recorded as digital information, and based on that file, we can modify the result, logically correct errors, and finally generate a MIDI file. Our system reduces misrecognition, and a wider range of music score can be recognized because we have implemented distortion correction and vertical line detection. We show that the proposed method is practical, and that is has potential for wide application through an experiment with a variety of music scores.

지금까지 음악 정보를 표현하기 위하여 SMDL, NIFF, MIDI를 비롯한 많은 방법들이 제시되었다. 그러나 기존의 방법들은 독자적인 표현 방식을 사용하므로 서로 호환되지 않으며, 구현 방법과 과정이 매우 복잡한 문제점을 갖고 있다. 그리고 해당 어플리케이션의 가격이 매우 고가이므로 일반인들이 쉽게 접할 수 없었다. 따라서 본 논문에서는 이와 같은 문제점들을 해결하기 위하여 음악정보, 특히 리듬정보를 웹 표준 언어인 XML을 이용하여 표현하고 이를 웹에서 편집 및 재생하기 위한 새로운 방법을 제시하고 시스템을 구현한다. 그 결과 XML에 근거한 우리의 시스템은 일반인들이 쉽게 접할 수 있는 웹에서의 음악정보의 편집 및 출력, 그리고 사운드로의 재생 기능을 제공하는 동시에 완벽한 음악 정보의 호환을 이룰 수 있다.

The strain KKI isolated from soil contaminated with polycyclic aromatic hydrocarbons was identified as Pseundomonas sp. based on analyses by MIDI and Biolog Identification System. Cellular and physiological responses of strain KKI to two-ring polycyclic aromatic hydrocarbon, naphthalene were evaluated using radiorespirometry, PLFAs and sequence analysis of Rieske-type iron sulfur center of dioxygenase. KKI was found to be able to rapidly mineralize naphthalene. Notably, KKI cells pregrown on phenanthrene were able to mineralize naphthalene much more rapidly than naphthalenepregrown cells. The total cellular fatty acids of KKI were comprised of eleven C-even and two C-odd fatty acids (fatty acids < 0.2% in abundance were not considered in this calculation). Lipids 12:0 2OH, 12:03 OH, 16:0, 18:1 6c, 18:0 increased for naphthalene-exposed cells, while lipids 18:1 7c1/15:0 ism 2OH, 17:0 cyclo, 18:1 7c, 19:0 cyclo decreased. Data from Northern hybridization using a naphthalene dixoygenase gene fragment cloned out from KKI as a probe provided the information that naphthalene dioxygenase gene was more highly expressed in cells grown on phenanthrene than naphthalene.

In general, we thought only composers can compose musics. And now we should have opportunities to make some musics by Computer Music System which called 'MIDI', but the composition is still unfamiliar to non musician men or women. In this report, we exhibit the possibility of the auto code composition by computer program which should make non musician men or women to composers.

본 논문에서는 악보 영상을 인식하고 이를 연주할 수 있는 시스템을 제안한다. 이 시스템은 스캐너 또는 카메라로 악보 영상을 입력 받는다. 먼저 입력 영상을 전처리하여 영상 분석에 알맞은 형태로 변환시키고 선 추적으로 오선을 추출한 후, 템플릿 매칭을 이용해 음표, 쉼표, 보표, 조표 등을 추출하여 인식한다. 그리고 인식한 결과를 MIDI로 출력한다. 이 악보 인식 시스템을 통해 여러 실험 데이터를 검토해 본 바, 본 시스템이 실용적임을 보였다.

A bacterial consortium capable of utilizing a variety of polycyclic aromatic hydrocarbons has been isolated from a former manufactured gas plant site. The consortium consisted of four members including Arthrobacter sp., Burkholderia sp., Ochrobacterium sp., and Alcaligenes sp., which were identified and characterized by the patterns of fatty acid methyl esters (FAME analysis) and carbon source utilization (BIOLOG system). With the individual members, the biodegradation characteristics of aromatic hydrocarbons depending on different growth substrates were determined. FAME analyses demonstrated that microbial fatty acid profiles changed to significant extents in response to different carbon sources, and hence, such shift profiles may be informative to characterize the biodegradation potential of a bacterium or microbial community.
