Modification of the phase gradient formulation is proposed in order to make phase retrieval less susceptible to noise. The modified formulation is derived from separation of the phase terms and the intensity modulation terms of interferograms, and subsequent differentiation to reduce the noise-induced error of the phase gradient vector. Its performance is evaluated and compared to that of the conventional formulation, and noise-robust nature is confirmed.

Mean F0, Jitter, Shimmer, and NHR were measured in 21 opera singers, 13 Korean traditional 'pansori' singers, and 21 non-singers. Four voice sampling conditions were ordinary /α/ prolongation, /α/ prolongation using vocal technique as if the subjects were singing, oral reading of the words of a song, and singing. One-way ANOVA and Sheffe post-hoc analysis were used to identify significant differences among the groups. The mean F0 was significantly different among the 3 groups in all conditions except for the ordinary /α/ prolongation condition. The opera singers produced lower jitter and NHR compared to 'pansori' singers and non-singers only in the singing condition.

In general, performing facilities consist of various functional groupings. The functional groupings should be arranged, in relation to each other, depending on the circulation of users in a space. The performing culture in Korea has been rapidly progressed in recent years. However, compared to the superior examples of foreign performing facilities, it still needs improvements and systematic research. In this study, the functional groupings of general performing facilities as well as the circulation patterns of users will be analyzed. From the results of this study, a circulation system for each spatial composition will be suggested for the performing facilities to be constructed in the future.

경극은 중국의 전통극 중 하나이다. 경극의 영어 명칭은 'peking Opera'다. 경극의 "분장"은 희극에서 배우들이 얼굴에 하는 채색 화장을 가리킨다. 경극 배우들의 얼굴 분장을 '검보'라고 한다. 형태, 색채와 유형 면에서 특별한 양식을 갖춘다. 본 논문은 중국에 전하는 가면극의 외면적 표현 형태를 시각디자인 조형영역 분석을 통해 학문적 가치를 창출하는데 목적이 있다. 본 논문의 연구 영역은 경극의 유래, 색채, 형식적 측면에 대한 조형분석과 가면의 표현형식, 즉 표형기법, 색상구성, 형태구성, 역할특성 등의 구성형식을 조형적 분석 틀에 의해 분석하고자 한다. 가면 얼굴의 대표문양 분석을 통해 단순화 표현형식으로 작품을 만들어 연구하고자 한다. 분 논문의 의의는 중국 전통경극의 집중적 연구의 결과 추출을 통해 한국의 유사 전통탈춤과 비교하는 연구의 귀중한 자료로 예측되기에 본 연구를 진행하였다.

An acoustical rating for the occupied hall of our National Theatre is presented for symphony orchestra and opera by theoretical estimation of various acoustical qualities from the basis of measured reverberation times in its vacant stste. The result is that by serious poverty of liveness a romantic music, typical symphony orchestra and even classical music are very difficult to be performed and only a baroque music is scarcely allowable to be performed in this hall. As for opera, wagnerians are difficult and italians are performable to some extent. Some discussions are given for which defects are more serious in this hall and some possible accustical corrections are also suggested for its better performance.

Pansori (sole narrative music), a typical folk music genre of Korea, resembles Western opera in its dramatic appeal, but greatly differs from Western opera in its use of musical scales, rhythms and singing methods. The followings are the differences observed between the voice producing method in Pansori and that in bel canto singing in Western music. (omitted)

An optimized iron core structure of stimulating coil are presented in order to control the induced electric field distribution using the Continuum Design Sensitivity Analysis (CDSA) combined with a commercially available generalized finite element code (OPERA). The results show that a Figure-Of-Eight (FOE) coil as well as a circular coil with the proposed iron core structure can increase induced electric field intensity by more than two times and make better field localization, compared with those of existing stimulation coil with a air core. After considering manufacturing constraints, a practical iron core structure based on the proposed optimized one is proposed and its performance is analyzed.

In this study, the influence of surface roughness on light scattering from Au pads on a PCB surface was investigated. Angular distributions of light scattered from Au pads with different surface roughness were measured for several incident angles. Diffusely-scattered light could be separated by using the fact that the amount of specularly-scattered light was directly related to surface roughness. The separated diffuse term was curve-fitted with a physics-based model, and then the related scattering parameters were extracted and compared with measured parameters.

The purpose of this study is to examine the effect of the quality of performance on audience satisfaction, and to verify the mediating effect of service value and traditional image in this process. The subjects of this study included 211 male and female adults who experienced the Korean opera performance in Seoul, Korea in October. Collected data was used as a model of path coefficients obtained through analysis of covariance structure and hypothesis test. As a result of verification, program quality, physical environment quality, and quality of the stage performance perceived by the audience showed a statistically significant positive correlation with performance experience attributes. The path coefficient between performance attribute and service value, performance experience attribute and traditional image were also positively and statistically significant. Further, the path coefficient between performance experience and audience satisfaction showed a positive relationship. The service value and traditional image, service value and audience satisfaction, and the path coefficient between traditional image and audience satisfaction were statistically and positively significant. Finally, all hypotheses were adopted and study results confirmed the effect of service quality and experience attributes on audience satisfaction for the popularization, modernization and marketing strategy of the Korean opera. In this process, it is meaningful to verify the role and function of service value and traditional image.
