  • Superior performance of field consistent eight-node hexahedron element in static bending problems has already been demonstrated in literature. In this paper, its performance in free vibration is investigated. Free vibration frequencies of typical test problems have been computed using this element. The results establish its superior performance in free vibration, particularly in thin plate application and near incompressibility regimes, demonstrating that shear locking, Poisson's stiffening and volumetric locking have been eliminated.

  • Purpose: This study is to investigate the influencing factors in the consistent use of contraception methods by comparing consistent and inconsistent users on partner communication, contraceptive control perception, and sexual autonomy among married Korean women. Method: This study consists of 243 married women living in Korea. A convenient sampling technique was used and data were collected by self report questionnaires from September 14, 2000 to October 20, 2000. Result: Only 41.6% of women were using contraception methods consistently and the rest of them were using contraception methods inconsistently. Between the two groups, statistical significances were noted in sexual communication(t=-2.5, p=.01), perceived contraceptive control(t=-7.5, p=.00) and sexual autonomy(t=-3.1, p=.00). As for general communication, it was not statistically significant(t=-1.0, p=.31). Conclusion: Family planning program advisors should recognize that intervention programs for the promotion of consistent contraceptive behavior should focus on the sexual communication, perceived contraceptive control, and sexual autonomy.

  • In order to properly quantify fission reactor neutronics parameter uncertainties, we have to use covariance data and sensitivity profiles consistently. In the present paper, we establish two consistent methodologies for uncertainty quantification: a self-shielded cross section-based consistent methodology and an infinitely-diluted cross section-based consistent methodology. With these methodologies and the covariance data of uranium-238 nuclear data given in JENDL-3.3, we quantify uncertainties of infinite neutron multiplication factors of light water reactor and fast reactor fuel cells. While an inconsistent methodology gives results which depend on the energy group structure of neutron flux and neutron-nuclide reaction cross section representation, both the consistent methodologies give fair results with no such dependences.

  • A relation between temperature and time has been constructed in the self-consistent model(SCM). This relation is used to calculate the a CMBR temperature. This temperature has been found to be 2.9K. The temperature gradient of microwave background radiation(CMBR) is calculated in the Self Consistent Model. Two relations between Hubble parameter and time derivative of the temperature, have been presented in two different cases. In the first case the temperature is treated as a function of time only, while in the other one, it is assumed to be a function in time and solid angle, beside the assumption that the universe expands adiabatically.

  • A consistent general order nodal method for solving the 3-D neutron diffusion equation in (x-y-z) geometry has ben derived by using a weighted integral technique and expanding the spatial variables by the Legendre orthogonal series function. The equation set derived can be converted into any order nodal schemes. It forms a compact system for general order of nodal moments. The method utilizes the analytic solutions of the transverse-integrated quasi -one dimensional equations and a consistent expansion for the spatial variables so that it renders the use of an approximation for the transverse leakages no necessary. Thus, we can expect extremely accurate solutions and the solution would converge exactly when the mesh width is decreased or the approximation order is increased since the equation set is consistent mathematically.

  • 본 연구는 브랜드 확장의 단점에도 불구하고 마케팅의 효과 및 효율측면에서 항상 고민하는 마케터들이 전략적으로 브랜드확장을 꾀하고자 할 때, 브랜드확장의 위험을 줄이고 성공가능성을 높이는데 일조하고자 실시되었다. 특히 본 연구는 제품유형을 실용제품과 쾌락제품으로 구분하고, 모 브랜드의 제품유형과 일치하는 제품유형으로 브랜드 확장을 하는 경우와 불일치하는 제품유형으로 확장하는 경우에 소비자가 확장 브랜드에 대하여 보이는 반응을 조사하였다. 연구결과에 따르면, 모 브랜드의 제품유형과 일치하는 제품유형으로 확장한 브랜드가 불일치하는 제품유형으로 확장한 브랜드보다 소비자에게 보다 긍정적으로 평가를 받았다. 또한 브랜드확장 전략 수행 시 모 브랜드와 제품유형을 일치시키는 것이 모 브랜드의 제품유형이 쾌락제품일 경우보다 실용제품일 경우 더욱 중요한 것으로 나타났다. 여기에서 나아가 소비자가 몰입하는 인지적 또는 감성적 관여유형에 따라 브랜드확자엥 대한 보지가의 평가는 모 브랜드의 제품유형 및 일치 불일치 확장유형에 따라 달라질 수 있음을 알 수 있었다.

  • 심층 생성 모델의 일종인 Generative Adversarial Network(GAN)과 Variational AutoEncoder(VAE)는 비병렬 학습 데이터를 사용한 음성 변환에 새로운 방법론을 제시하고 있다. 특히, Conditional Cycle-Consistent Generative Adversarial Network(CC-GAN)과 Cycle-Consistent Variational AutoEncoder(CycleVAE)는 다수 화자 사이의 음성 변환에 우수한 성능을 보이고 있다. 그러나, CC-GAN과 CycleVAE는 비교적 적은 수의 화자를 대상으로 연구가 진행되어왔다. 본 논문에서는 100 명의 한국어 화자 데이터를 사용하여 CC-GAN과 CycleVAE의 음성 변환 성능과 확장 가능성을 실험적으로 분석하였다. 실험 결과 소규모 화자의 경우 CC-GAN이 Mel-Cepstral Distortion(MCD) 기준으로 4.5 % 우수한 성능을 보이지만 대규모 화자의 경우 CycleVAE가 제한된 학습 시간 안에 12.7 % 우수한 성능을 보였다.

  • The problem of wavelet density estimation is studied when the sample observations are contaminated with random noise. In this paper a linear wavelet estimator based on Meyer-type wavelets is shown to be L$_1$ strongly consistent for f(x) with bounded support when Fourier transform of random noise has polynomial descent or exponential descent.
