This study attempts to propose a pattern design of snug fitting midi briefs for women. Each briefs made of two kinds of fabric, cotton 40's and cotton 40's spandex, was produced for the research in a different shrinkage rate. The result of wearing test of the briefs-sold-in-the-market (BSM) and the briefs-specially-made-for-this-research (BSMR) were as follows: BSMR showed a higher mark than that of BSM in the sense of close fit on the torso, comfortableness, sense of being tight, satisfaction and beauty. In particular, the back design line of BSM gave a lower satisfaction to test wearers, while that of BSMR gave a more comfortableness to them, making their hip comfortably being wrapped by making smoother the angle of the straight line linking sidelines with clutch part, and making sidelines into curve. In a forward research, further studies about grading and other patterns but midi pattern of briefs would be examined.

Soybean sprout pathogenic bacteria were isolated from the large, deep containers of a commercial factory. Over a period of one year, 40 pathogenic-like bacteria were isolated among a total of 732 isolates. In addition to bacteria previously reported to be associated with rotting, such as Pseudomonas putida and Erwinia carotovora, several other genera were also identified: Acinetobacter spp., Chryseobacterium spp., Klebsiella sp., Pantoea agglomerans, Bacillus sp. Fatty acid methyl ester (FAME) analysis using the Microbial ID (MIDI) system, and 16s rRNA sequence analysis, yielded identical results, confirming the identities of these microorganisms. Several types of selective media were not good for identification and determination of population structure in commercial environments, as colony type was not specific to the genus. There was no dominant bacterium, and we were not able to find the main bacterium responsible for soybean spout rot. Even though we did not identify a major target for controlling rot or screening for resistant cultivars, the results of this study indicated that bacterial rot of soybean sprout is endemic. In addition, it emerged that factory epidemics in summer are not caused by the bacteria isolated in this study.

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.

This paper considers a nonparametric estimation of lifetime distribution for ramp stress tests with stress bound under intermittent inspection. The test items are inspected only at specified time points an⊂1 so the collected observations are grouped data. Under the cumulative exposure model, two nonparametric estimation methods of estimating the lifetime distribution at use condition stress are proposed for the situation which the time transformation function relating stress to lifetime is a type of the inverse power law. Each of items is initially put on test under ramp stress and then survivors are put on test under constant stress, where all failures in the Inspection interval are assumed to occur at the midi)oint or the endpoint of that interval. Two proposed estimators of quantile from grouped data consisting of the number of items failed in each inspection interval are numerically compared with the maximum likelihood estimator(MLE) based on Weibull distribution.

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. Separating technique for singing voice from music accompaniment is very useful in such equipment. We propose a system to separate singing voice from music accompaniment for stereo recordings. Our system consists of three stages. The first stage is a spectral change detector. The second stage classifies an input into vocal and non vocal portions by using GMM classifier. The last stage is a selective frequency separation stage. The results of removed by listening test from the results for computer based extraction simulation, spectrogram results show separation task successfully. Listening test with extracted MR from proposed system show vocal separating and removal task successfully.

We present photometric results for four new variable stars discovered in the vicinity of the ZZ Ceti-type pulsating white dwarf BR Cam. Observations were performed on 5 nights in November 2003 using the 1.8m telescope at Bohyunsan Optical Astronomy Observatory with no filter, on 3 nights in December 2003 using the 0.61m telescope at Sobaeksan Optical Astronomy Observatory with V, I filters, and on 3 nights in October 2004 using the 1.0m telescope at Mt. Lemmon Optical Astronomy Observatory with V, I filters. We estimated their periods from the phase-match technique for one eclipsing binary and the multiple frequency analysis for three pulsating stars. By considering the light curve shape, period and amplitude difference between two passbands, we classified the objects by their variability types as follows: V1 (USNO-A2.0 1425-05691757) is a W UMa-type eclipsing binary with an orbital period of $0^d.4641$; V2 (USNO-A2.0 1425-05703335) is a multi-periodic $\delta$ Set-type pulsating star with a dominant period of $0^d.0649$; V3 (USNO-A2.0 1425-05699659) is also a $\delta$ Set-type pulsating star with a period of $0^d.1408$; and V 4 (USNO-A2.0 1425-05707705) is a RR Lyr-type pulsating star with a period of $0^d.2643$.

The purpose of this study was to provide basic materials for the brief patterns and design development for the elderly women to select number 1 to 3 brands according to their brand preference surveying the elderly women with average shapes, and to compare and analyze the exterior fit and functionality. Accordingly, this study proposed basic materials needed for panty pattern suitable for average shapes of the elderly women. The results of the study are as follows: 1 . Looking into the style, they preferred white the best. Regarding the patterns, almost half preferred patterns and rest of them did not. With the panty with patterns, they wanted small and implicit flower patterns. The design they liked was midi, maxi and then mini in order. When looking into the brands, they preferred 'Company B', 'Company SS', 'Company SY', and then market products. The reason why they selected those panty was feeling of fitness, price and then material. 2. To classify the figures of elderly women, we grouped the subjects with strata method using minimal dispersion method. Type 1 is the average, type 2 is for obese women and type 3 is slender women. 3. 3 brands were selected that were produced using CM 40's and elderly women preferred best. When executing wearing test on two elderly women who have average figure according to the body measures in previous study and body measure of Size Korea total exterior evaluation score was Company A, B and C in order.

최근 원음 반주기에 대한 관심이 증가됨에 따라 고가의 스튜디오 직접 녹음 방법 대신 보다 저렴한 방법을 시도하고 있다. 그 구체적인 방법으로는 가수의 음악 앨범에서 가수의 목소리만 제거하여 원음 반주 음원을 만드는 것이다. 본 논문에서는 스테레오로 녹음된 반주음악에서 보컬을 분리하는 시스템을 제안한다. 제안하는 시스템은 두 단계로 구성된다. 첫 단계는 보컬을 검출하는 단계이다. 이 단계에서는 MFCC를 가지고 SVM 방법을 이용하여 입력 신호를 보컬 부분과 비보컬 부분으로 분리한다. 두 번째 단계에서는 보컬 부분에 대해 각 주파수 빈별로 선택적 주파수 차감을 수행한다. 제안하는 방법으로 보컬을 제거한 음악에 대한 청취실험에서 상대적으로 높은 만족도를 보여준다.
