Recently, we can hear various kinds of music in everywhere and anytime. If a user wants to find the music which was heard before in a street or cafe, but he does not know the title of the music, it is difficult to find it. That is the limitation of previous retrieval system of music data. To overcome these problems, we research a method of content-based retrieval of music data based on the recorded humming, the part of recorded music and the played musical instrument. In this paper, we investigated previous content-based retrieval methods of papers, systems and patents. Based on that, we research a method of content-based retrieval of music data. That is, in case of using the recorded humming and music for query, we extract the frequency information from the recorded humming/music and the stored music data by using FFT. We use a MIDI file in case of query by the played musical instrument. And by using dynamic programming matching, the error caused by the disparity of length between the input source with the stored music data could be reduced.

Thirty bacteria were isolated from the red pepper rhizosphere. The isolates were screened for antagonism to Alternaria alteranta causing red pepper black rot. Antagonistic bacterium No. J-24 was selected among the isolated bacteria and was identified as Bacillus subtilis based on morphological and physiological characteristics and MIDI system. B. subtilis J-24 showed antifungal activities against A. alternata(inhibition percentage, 99%), Botrytis cinerea, Phytophthora capsici, Pythium ultimum, Colletotrichum gloeosporioides, Stemphylium botryosum. The growth of red pepper seedling was promoted as compared to control when the microbial inoculants was mixed in bed soil. In the mixed microbial inoculants bed soil, the leaf area of red pepper was increased of 15 percent, the hypocotyl weight 12 percent, the root length 12 percent, total dry weight 13 percent as compared to those grown in the general bed soil.

In spite of controversial debates on aesthetic issues of computer-generated electronic music, rapid advancement of music technologies in the past decade have resulted proliferation of using virtual software synthesizers and samplers in music composition. Computer-based music production platform has become not only a norm among some of contemporary music composers but also vital apparatus for their compositional process. There are two imperative parts of this compositional process involving sampling in computer-based music production, which are commercially available sample libraries that include pre-recorded audio samples, and music production software that processes them. The purpose of this study is to investigate the process and effectiveness of reconstructive compositional process utilizing distinctive features of sampling on computer music production software. This study addresses issues such as: the definition of audio sampling, how sampling is incorporated in compositional process, and what features of music production software are particularly effective in various musical expressions. The result of this study will hopefully accommodate and fulfill the needs of electronic and acoustic musicians' creativeness.

Recent performing-art has a trend to be new cultural contents style which mixes various genre not just traditional way. Especially in stage performance, unique performance is playing using high technology and image. In sound performance, one of technology, a new experiment is trying which re-analyze the sound and mixes the result with image. But in public performance we have a technical difficulty with making visualization regarding the sound in realtime. Because we can not make visualization with instant sound from performers and audience it is difficult to interact smoothly between performer and audience. To resolve this kind of restriction, this paper suggests Real-time sound visualization. And we use string music instrument for sound source. Using the MaxMSP/Jitter based the Midi, we build image control system then we test and control the image with Korg Nano Kontrol. With above experiment we can verify verious emotion, feeling and rhythm of performer according to performance environment and also we can verify the real time interactive image which can be changed momently by performer's action.

Recently, According to increasing interest to original sound Karaoke instrument, MIDI type karaoke manufacturer attempt to make more cheap method instead of original recoding method. The specific method is to make the original sound accompaniment to remove only the voice of the singer in the singer music album. In this paper, a system to separate vocal components from music accompaniment for stereo recordings were proposed. Proposed system consists of two stages. The first stage is a vocal detection. This stage classifies an input into vocal and non vocal portions by using SVM with MFCC. In the second stage, selective frequency subtractions were performed at each frequency bin in vocal portions. In this case, it is determined in consideration not only the energies for each frequency bin but also the phase of the each frequency bin at each channel signal. Listening test with removed vocal music from proposed system show relatively high satisfactory level.

In 21C, computer is having a powerful influence on every fields. As music field is no exception, the computer music is regarded as a next generation music. Especially the focus of 21st century's music is now moving from MIDI of 20th century to the Realtime interactive music in which computer is used as a practical instrument. Most european countries and America are doing a lot of research and performing these music. But in Korea, known as a fairly strong IT country, there is no enough perception of the importance of this new outcome of the new media era, and introduction of this music is slow as well. In this paper, we suggest the possibility of using the new way of composition by realtime interactive music in Korea. This can be a strong merit for Korean composers who want to use Korean instruments which were limited to be used as international instruments because of their restricted registers, techniques and so on.

The Compost-decomposing-bacteria was isolated from livestock compost containing sawdust. The isolated bacteria was identified as Bacillus subtilis LYH201 by the method of the composition of the fatty acid with MIDI system and Bergey's manual. Cloning of CMCase encoding gene was accompanied by shotgun method. The pLK100 have yellow activity ring on CMC medium, that was carried 2.2 kb insert DNA in pBluescript II $SK^+$ vector, named BglC gene. The BglC was very similar to Pectobacterium carotovorum Gun_CLOAB(P15704) with score of 57% identity and 71% homology over 508 aa. The BglC was measured molecular weight 56 kDa by CMC-SDS-PAGE. Optimum cellulase activity Bacillus subtilis LYH201 was temperature $50^{\circ}C$ and pH 7.

Twelve antagonistic strains against Fusarium wilt of watermelon-rootstock gourd were selected from 54 bacterial isolates which were isolated from the rhizosphere of crop plants growing in various locations. They showed strong inhibitory effects on growth of Fusarium osysporum f. sp. niveum, the causal agent of watermelon-rootstock gourd Fusarium wilt. Among these antagonists, the isolate YJ-3 was the most pronounced in growth-promoting ability for watermelon-rootstock gourd. The growth of watermelon-rootstock gourd in bed soil inoculated with YJ-3 was better by 46 and 13% than those in commercial bed soil alone and in bed soil inoculated with commercial microbial inoculant, respectively. The antagonistic plant growth-promoting rhizobacterium, strain No. YJ-3, was identified as Bacillus sp. on MIDI system. Furthermore, Bacillus sp. YJ-3 showed antifungal activity on growth against Alternaria cucumerina, Botrytis cinerea, Colletotrichum orbiculare, Didymella bryoniae, Rhizoctonia solani and Fusarium oxysporum.

The role of fashion image in modern society is being diversified from product planning to consumer satisfaction. In this research, after surveying female college students, the diversified modern fashion image was patterned. On the analogy of the relationship between these patterned image and design factors, the following conclusion was obtained. 1. The most popular styles are jacket and pants suits, three-piece outfits, tight mini-skirts and X-silhouette. Little decoration is used in general. simplicity is shown as trend by utility fabrics in single color-black, brown, beige and blue-with no pattern. Various materials such as wool, cotton, wool or cotton blended with other materials, silk, satin, knit, lace, vinyl and leather are used. 2. Fashion image is divided into four factors; factors that show fad, dignity, activity and simplicity. 3. Factors that show fad; style of tops, material of bottoms and length of bottoms reflect fad. blousons, three-piece outfits, pants rather than skirts, X-silhouette and mini-skirts are prevailing. Vinyl, leather, knit, lace and satin are the materials well used. 4. Factors that show dignity; Style and material of tops, the way of top and bottom pieces are matched and length of bottom or pieces reveal the characteristics. Jackets, blouses, half-coats and one-piece outfits rather than two-pieces are popular. Tight skirts in natural or midi length or pleated skirts are common. Wool, wool blended with other materials, leather and X-silhouette are design factors that reveal dignity well. 5. Design factors that show active image; Straight pants, three-piece outfits, T-shirts, shirt -blouses, vests, and blausons are popular. Knit and lace are used for tops, leather and vinyl are used for bottom pieces and cotton is widely used. Y- or H-silhouette are used to show active image.
