By reading the main character, Rene Gallimard, in M. Butterfly as a spatial metaphor of America, this article examines how homogeneous American national identity of heterosexuality and white masculinity has been reinforced since the cold war and has constituted a crisis of hegemony with the decline of imperialism and how its pathological symptom is shown through the melancholic suicide of Gallimard. This article also argues how the feminine attributes implied in race, gender and sexuality in M. Butterfly are designated and allegorized as an impure, contaminated and ahistorical marker of national integrity in pthe social and material status of the heterosexual American white male. To develop my argument, I read M. Butterfly from a psychoanalytic point of view. Therefore I depend on Freud, Lacan, and Bhabha's psychoanalysis as the theoretical basis. In this paper, I also argue that the homogenized and fixed national identity is splitted and collapsed from within as shown in the Gallimard's melancholy and in the process of splitting the "Third Space" of hybrid subjects for the marginal and the emergent like Song Liling, a homosexual Asian man, can be built "from a space in-between." Therefore Hwang calls into questions conventions of fixed, essentialist identities through the shifting gender identities between Song and Gallimard in M. Butterfly and how identities in the plural are constructed variously in throughly historicized, politicized situations, and these constructions can be complicated by relations of power.

In Oriental medicine, the status of tongue is the important indicator to diagnose one's health, because it represents physiological and clinicopathological changes of inner parts of the body. The method of tongue diagnosis is not only convenient but also non-invasive, therefore, tongue diagnosis is one of the most widely used in Oriental medicine. But tongue diagnosis is affected by examination circumstances a lot. It depends on a light source, degrees of an angle, doctor's condition and so on. So it is not easy to make an objective and standardized tongue diagnosis. As part of way to solve this problem, in this study, we tried to design a discriminant function for white and yellow coating with multi-dimensional color vectors. There were 62 subjects involved in this study, among them 48 subjects diagnosed as white-coated tongue and 14 subjects diagnosed as yellow-coated tongue by oriental doctors. And their tongue images were acquired by a well-made Digital Tongue Diagnosis System. From those acquired tongue images, each coating section were extracted by oriental doctors, and then mean values of multi -dimensional color vectors in each coating section were calculated. By statistical analysis, two significant vectors, R in RGB space and H in HSV space, were found that they were able to describe the difference between white coating section and yellow coating section very well. Using these two values, we designed the discriminant function for coating classification and examined how good it works. As a result, the overall accuracy of coating classification was 98.4%. We can expect that the discriminant function for other coatings can be obtained in a similar way. Furthermore, if an automated segmentation algorithm of tongue coating is combined with these discriminant functions, an automated tongue coating diagnosis can be accomplished.

현재 우리 나라의 각종 건설공사에 수반되는 암반 굴착작업은 아직까지 화약류에 의한 발파공법이 주를 이루고 있는 실정이다. 이는 발파공법이 다른 굴착방법에 비하여 경제성 및 작업 효율성 등에서 효과적이기 때문이다. 그러나, 도심지에서 발파작업은 작업에 수반되는 환경 공해적 요소인 소음, 진동, 암석의 비산 및 분진 등의 끊임없는 민원발생과 많은 피해가 발생되어 미진동 및 무진동 굴착방법이 대체공법으로 사용되고 있기는 하나 이들은 경제성 및 효율성이 낮아 궁극적인 해결책이 절실히 요구되고 있는 실정이다. 따라서 본 논문에서는 백열광에 의해 유도된 열 응력 (인장 및 전단 응력)을 이용한 무진동, 무소음 암반 파쇄공법의 특성, 암석파쇄효과 및 경제성에 대하여 검토하였다. 본 연구에서 백열광에 의한 암반굴착방법은 500Kw의 전력소비로 $16ft{\times}16ft$정도의 터널단면을 하루에 약 90ft 굴진이 가능한 것으로 분석되었다. 또한 본 굴착방법은 전기를 동력원으로 이용하기 때문에 화약발파에 의한 작업 중단이 필요 없으며 화이트라이트 유니트를 추가로 설치하면 굴착속도를 더욱 단축할 수 있게 된다.

전기자극이 흰쥐의 정상근에 어떠한 영향을 미치는지를 알아보기 위하여 좌골신경의 표적근인 가자미근을 이용하여 조직계측학적, 조직화학, 전자현미경적 관찰을 하였다. 정상적으로 활동하는 흰쥐의 골격근을 매일 전기자극한 결과 전기자극군은 자극을 시작한 후 2주까지는 근섬유의 굵기와 무게가 증가하고 그 이후로는 큰 변화가 없었다. 특히 근섬유의 종류별로는 적색섬유(red muscle fiber)의 채적밀도가 증가하였고 백색섬유(white muscle fiber)는 줄어드는 양상을 보였다. 조직화학적 검사 결과 전기자극군은 근섬유가 다소비대(hypertrophy)해지고 내근주막과 외근주막 사이가 좁아져 있었다. 정상근에서는 당원이 근섬유의 뚜렷한 구별없이 양성반응을 보였으나 실험군은 특정 근섬유에만 반응이 나타났었다. 또한 NADH-TR반응 결과 전기자극군은 적색섬유가 유의하게 증가하여 생체계측학적 결과와 일치하였고 미세구조적 관찰 결과 정상근의 적색섬유는 근섬유와 평행으로 mitochondria가 형성되어 있었고 백색섬유에서는 근절부위에서 관찰되었다. 그러나 전기자극군에서는 적색섬유는 근초부위에 mitochondria가 많이 관찰되고 백색섬유도 근절부위에 작은 mitochondria의 수가 증가되는 것을 관찰할 수 있었다.

This study comparatively analyzed the images and preference of lighting space using the emotion-based technique in order to effectively use it in clothing shops and fashion marketing. In terms of color temperature for light sources, 2,800K of lamp color, 6,500K of daylight color and 4,200K of white color were used. For the assessment, sensory evaluation technique was used. Then, the study found the followings: In terms of the image of lighting space by light source, different images were observed by light source with significant difference by the evaluation category. For factor analysis by the evaluation category, 7 factors were extracted. Among them, evaluation on lighting space was influenced by the following three images: modern space, elegant space and classical space. In particular, the modern space comprised of the following adjectives had the biggest effect on the assessment of the image of lighting space ('refreshing,' 'transparent,' 'bluish,' 'bright' and 'non-classical') (primary evaluation 30.13%). According to assessment on the preference of lighting space, the respondents' most favorite lighting space was 4,200K while their least favorable one was 6,500K in terms of color temperature. In terms of preference by the image of lighting space, they didn't like 'non-elegant' and 'non-beige' images even though they had the images of modern space. Therefore, it was confirmed that beige and elegant space images have an effect on the preference of lighting space.

The purpose of this study is to apply the basic data of the color plan to satisfy the internal desire of residents by considering residents's special in housing space. So we analyzed and surveyed the current condition of color plan in housing space where age units of 30~40 are living. The results of this study are as followed. when the current place of color distribution was observed, ceiling and general wall showed that N(white) systems and YR of bright tone was mostly distributed. On other hand the bottom showed that the calm tone YR was mostly distributed. we could know that residents wanted to show the special of rooms by using point wall. This tendency more presented in privacy room than public room. Through this study, we could evaluate that the special of residents is not presented in color plan of the housing space where age units of 30~40 are living. So we could think that it is needed methods of color plan considered the special of residents for discriminative characteristic of the design in housing space.

We have identified 22 quasars in the AKARI far-infrared all-sky Bright Source Catalogue, using a matching radius of < 10", and excluding matches which are close to foreground extended sources or cirrus. We have confirmed a relation between quasar optical luminosity and far-infrared luminosity which was found in an earlier study. In addition, we have found that the 11 sources which are at redshift z > 1 are magnified with respect to the predicted far-infrared luminosity, and consider this may be due to gravitational lensing. If confirmed, this would provide a new way to identify lenses; if not, we may have identified an interesting new population of extreme starbursting quasars.

A 4+12+16 amplitude phase shift keying (APSK) modulation outperforms other 32-APSK modulations in a nonlinear additive white Gaussian noise (AWGN) channel because of its intrinsic robustness against AM/AM and AM/PM distortions caused by the nonlinear characteristics of a high-power amplifier. Thus, this modulation scheme has been adopted in the digital video broadcasting-satellite2 European standard. And it has been considered for high rate transmission of telemetry data on deep space communications in consultative committee for space data systems which provides a forum for discussion of common problems in the development and operation of space data systems. In this paper, we present an improved bits-to-symbol mapping scheme with a better bit error rate for a 4+12+16 APSK signal in a nonlinear AWGN channel and propose a simple signal detection algorithm for the 4+12+16 APSK from the presented bit mapping.

The DEEP-South photometric census of small Solar System bodies is producing massive time-series data of variable, transient or moving objects as a by-product. To fully investigate unexplored variable phenomena, we present an application of multi-aperture photometry and FastBit indexing techniques to a portion of the DEEP-South year-one data. Our new pipeline is designed to do automated point source detection, robust high-precision photometry and calibration of non-crowded fields overlapped with area previously surveyed. We also adopt an efficient data indexing algorithm for faster access to the DEEP-South database. In this paper, we show some application examples of catalog-based variability searches to find new variable stars and to recover targeted asteroids. We discovered 21 new periodic variables including two eclipsing binary systems and one white dwarf/M dwarf pair candidate. We also successfully recovered astrometry and photometry of two near-earth asteroids, 2006 DZ169 and 1996 SK, along with the updated properties of their rotational signals (e.g., period and amplitude).
