We investigate the boundary values of the holomorphic mean Lipschitz function. In fact, we prove that the admissible limit exists at every boundary point of the unit ball for the holomorphic mean Lipschitz functions under some assumptions on the Lipschitz order. Moreover, we get embedding theorems of holomorphic mean Lipschitz spaces into Hardy spaces or into the Bloch space on the unit ball in $\mathbb{C}_n$.

BaO.nFe$_{2}$O$_{3}$ Powder ferrite magnet was made by sintering process. The purity of the powder were 99.6% far BaO. 99.5% for Fe$_{2}$O$_{3}$, and the grain size 1-3 micron. The Optimum mixing ratio n=4.4 the optimum density 4.8gr/cm$^{3}$ and the optimum second sintering temperature 1260.deg. C was found. The theoretical bloch wall, dimension of domain and energy per unit volume of BaFe$_{12}$O$_{19}$ were compared with pure Fe. Also, the saturation magnetization and maximum energy product were computed.d.d.

In the setting of the half-plane of the complex plane, we show that for r > $-{\frac{1}{2}}$, the dual space of the weighted Bergman spaces $B^{1,r}$ is the Bloch space and we introduce some operators. We also study Toeplitz and Hankel operators and we find some characterization of Hankel operators.

In the setting of the half-plane of the complex plane, we introduce a modified reproducing kernel and we show that for $r>-1/2,\;B^{1,r}-cancellation$ property holds and the Bloch space is the dual space of $B^{1,r}$.

Here we report the Ar-ion milling rates of ultrathin Si and GaAs single crystals. The thickness change is measured using convergent beam electron diffraction (CBED) technique with the help of Bloch wave simulation method. This study suggests the experimental procedures to determine the references for an etching rate to reduce a sample thickness or to remove the damaged sample surface using Ar-ion source.

This talk discusses conditions on the numerical range of a holomorphic function defined on a bounded convex domain in a complex Banach space that imply that the function has a unique fixed point. In particular, extensions of the Earle-Hamilton Theorem are given for such domains. The theorems are applied to obtain a quantitative version of the inverse function theorem for holomorphic functions and a distortion form of Cartan's unique-ness theorem.

Using the Huckel method, we obtain the analytical expressions for eigenvalues and eigenvectors of s.c., f.c.c. and b.c.c. clusters of rectangular parallelepiped shape, and of an arbitrary size. Our formula converage to those derived from the Bloch sum, in the limit of infinite extension. DOS and LDOS reveal that the major contribution of the states near Fermi level originates from the surface atoms, also symmetry of DOS curves disappears by the introduction of 2nd nearest neighbor interactions, in all the cubic lattices. An accumulation of the negative charges on surface of cluster is observed.

제품성공은 제품에 대한 소비자선호를 바탕으로 해서만 가능하며 제품에 대한 소비자선호는 그 디자인에 의해 가장 큰 영향을 받는다. 디자이너는 소비자선호에 대해 이해하고 그 선호를 특정 디자인요소들의 조합으로 전환하여 그들이 원하는 이미지의 제품을 디자인해야만 제품을 성공시킬 수 있다. 즉, 디자인 측면에서는 소비자선호구조 즉, 디자인선호도-디자인 이미지-디자인요소와의 관계를 명확하게 규명할 필요가 있다. 본 연구에서는 기존 연구들이 간과했던 소비와 디자인간의 상호관계를 확인할 수 있도록 디자인 선호도-디자인 이미지-디자인 요소들간의 명확한 인과관계를 규명하여 디자인 계획시 체계적인 지침을 제공하고자 한다. 이를 위해 디자인에 대한 소비자반응 프레임웍인 선호정도-이미지-디자인 요소들간의 명확한 인과관계를 규명할 수 있는 실마리를 제공하는 Bloch(1995)의 제품디자인에 대한 소비자반응이론을 고찰하여 연구모델을 구축하고 실증분석을 통해 디자인 선호도-디자인 이미지-디자인 요소들간의 관계를 분석하여 디자인할 수 있는 방법을 제공한다.
