In this paper we present a method of separating musical instrument sound sources from their monaural mixture, where we take the harmonic structure of music into account and use the sparseness and the overlapping NMF [1] to select representative spectral basis vectors which are used to reconstruct unmixed sound. A method of spectral basis selection is illustrated and experimental results with monaural mixture of voice/cello and trumpet/viola are shown to confirm the validity of our proposed method.

In order to determine the status of Enterobius vermicularis infection among schoolchildren in suburban areas of Myanmar, 761 primary schoolchildren in 3 different townships around Yangon City were subjected to a survey using cello-tape anal swabs. The subjected schoolchildren were 383 boys and 378 girls who were 5-7 years of age. Only 1 anal swab was obtained from each child. The overall egg positive rate of E. vermicularis was 47.2% (359 positives), and sex difference was not remarkable (48.6% in boys and 45.8% in girls). However, the positive rate was the highest in South Dagon (54.6%) followed by Hlaing Thayar (43.8%) and North Dagon (34.8%). This difference was highly correlated with the living standards of the people in each township. Nucleotide sequence of the 5S rDNA from the eggs on the cello-tape (2 children) revealed 99.7% identity with that of E. vermicularis reported in GenBank. The results indicated that E. vermicularis infection is highly prevalent among primary schoolchildren around Yangon, Myanmar.

Studies have been carried out to design a suitable consumer size package from flexible packaging material to hold 100 grams of Chilli powder and 250 grams of whole chilli which are moisture and color sensitive. 1. Sorption characteristics of the chilli powder has revealed that moisture sorption is rapid above 55 per cent R.H., and the product is fairly hygroscopic. Further, an equilibrium moisture content of about 15 per cent at 70 per cent R.H., appears to be critical from the point of microbial spoilage of chilli powder. 2. Studies on the colour (Capsanthin) changes of chilli powder equilibriated to different moisture content, have revealed that colour changes during storage is greatly influenced by the moisture content and temperature decreases the capsanthin content of chilli during storage. 3. From the studies, it can be inferred that the sunlight exhibits pronounced effect in bleaching of colour and brings about maximum discolouration of the red pigment in chilli. 4. From the packaging and storage studies of chilli powder in different flexible films, it can be concluded that for long-term storage, the aluminium foil laminate is unique in offering maximum protection from various physico-chemical changes. For short-term storage and for fairly good moisture and colour protection, amber or black polyethylene, high-density polyethylene and Saran/Cello/Saran poly laminate pouches appear to be suitable alternatives.

The purpose of this article is to discuss that ajaeng sanjo music playing (ASMP) can change a person's life. Ajaeng is often called a Korean cello and is the largest and lowest-pitched instrument in the string instrument family in Korean music. From far away it has a deep, low sound. Its low sound adds to its comfort and peace. Listening to a low tone music can help you calm down and heart-easing. As soon as he listened ajaeng sanjo music he felt that low sound is mildly under his patronage. He felt much more interesting energy and vitality about our minds and bodies are in ajaeng sanjo music. He could immerse himself in playing ajaeng sanjo music (ASMP) for several years. The Korean music, tune is one of expression, meaning it is inseparable from the feeling. Many studies show that low tone music not only activates brain power, but soothes minds. Music always stood by him during difficult times. In a word, ASMP leads him to change of life and music is the language of emotion to him.

An endo-$\beta$-1,4-glucanase gene of Clostridium thermocellum was cloned in Escherichia coli and was considered as a novel gene by comparison with the restriction patterns of the C. thermocellum cellulase genes so far reported. The endoglucanase from recombinant E. coli was purified by column chromatography after heat treatment. The purified enzyme was a monomer having molecular weight of 40,000. The enzyme hydrolyzed CMC to glucose and cello-oligosaccharides at :naximum activities at pH 5.0 and $65^{\circ}C$. One of the endproducts, glucose, showed no inhibitory effect on the enzyme activity, while the other endproduct, cellobiose, inhibited slightly. The values of $K_{m}$ and $V_{max}$ of the enzyme for CMC were 0.39% (w/v) and 268 Ulmg protein, respectively.

Fluorine-doped $SnO_2\;(SnO_2:F)$ films were prepared in ordinary atmosphere on borosilicate glass substrates using pyrosol deposition method starting from the solutions composed of $SnCl_4-5H_2O-NH_4F-CH_3OH-H_2O-HCl$ in an attempt to develop transparent conductors for use in amorphous silicon (a-Si) solar cello. The deposition rate of films increased with the increase in the content of $H_2O$, whereas it decreased with increasing the content of $CH_3OH$. When air was used as the carrier gas, the lowest electrical resistivity was obtained from a solution having $CH_3OH/H_2O$ mol ratio of about $2{\sim}3$ in the solution. The use of $N_2$ of the same flow rate as the carrier gab resulted always in the high resistive films, but the resistivity of the films decreased continuously with the increase in the content of $H_2O$. The surface morphology and preferred orientation of films were also affected by the solvent composition and the content of HCl in the solution. The room-temperature resistance of the films were fairly stable after heat-treatments up to $600^{\circ}C$.

A Rhizopus sp. was selected for its strong cellulolytic activity among various strains of molds found in rotting ginseng roots. Studies were made on some properties of the cellyloiytic enzyme produced by the strain. The results obtained were summarized as follows: The optimum pH of the enzyme was 4.5 and the range of its stability to the pH was 3.0 to 7.0. The optimum temperature was 5$0^{\circ}C$, while the enzyme was instantly inactivated above 6$0^{\circ}C$. Mn$^{＋＋}$ and Co$^{＋＋}$ ions increased enzyme activity and the metal ions were found to increased the ther-mostability of the enzyme. This enzyme was inhibited by sodium dodecyl sulfate and 2,4-dinitrophenol. This enzyme had a strong cellulolytic enzyme activity on various native cellulose given a sufficient reaction time. The addition of 0.5% saponin solution into reaction mixture increased the enzyme activity.

Energy conservation of server systems has become important. Though storage subsystem is one of the biggest power consumers, development of energy conservation techniques is challenging problem due to striping techniques like RAID and physical characteristics of hard disks. According to our observation, the size of footprint for a day or for hours is much smaller compared to the size of whole data set. In this paper, we describe a design of a novel architecture for RAID that uses an SSD as a large cache to conserve energy by holding such a footprint. We incorporate these approaches into a real implementation of a RAID 5 system that consists of four hard disks and an SSD in a Linux environment. Our preliminary results in actual performance measurements using the cello99 and SPC traces show that energy consumption is reduced by a maximum of 14%.

The purpose of this study was to investigate the effect of vocal and instrumental background music on a verbal memorizing task. Participants were 30 undergraduate and graduate students and were randomly divided into two groups. All participants in both groups took a pretest and a posttest to examine the improvement of the memorization. Background music was inserted during the memorization task. Subjects in Group A listened to a vocal recording whereas Group B listened to the same music except with a cello playing the melody of the vocal part. All participants were asked to take the posttest to examine the improvement of their knowledge after the memorization. The t-test was used to compare the two groups. Results indicated that Group A(8.93) exhibited higher mean scores than Group B(7.46) but there were no significant differences t(28) = 1.38, p < .05. This study implies that lyrics does not distract word memorization and background music does not influence cognition directly.
