The purpose of this study was to understand the effects of religion on Amish costumes. For this study I twice visited Amish village in Lancaster Pennsylvania U.S,A in July 1993 and August 1996. The methods of study directed direct observation and literature re-search. The results of this study were as follows: The Amish was livid practically by strict princi- ples of simplicity diligence piety and mutual cooperation. The Amish behavioral code of laws known as ordnung dictated appropriate dress agricultual methods and a routine for daily life. The Amish costumes originated with the 17th century Puritans traditional apparel the European farmer and the clothing style of 19th century Americal,. Amish costumes was fastened with hooks and eyes instead of decorative buttons a diret influence of Puritanism does and did non con-tain ornamental outer pockets. This distinctively simple costumes served as a boundary outsiders to and as a direct ex-pression of their faith. An Amish doll had neither facial features nor fingers and toes as described in scripture "You do not become corrupt and make for yourselves an idol an image of any shape whether formed like a man or a women or like any animal on earth or any bird that flies in the air or like any creature that moves along the ground or any fish in the waters below" In this way Amish costumes was affected by their religion and faith.

The purpose of this study was to investigate the father related variables on children's self-esteem and school adjustment. Father related variables were father's child-rearing involvement, fathers parenting behavior and father-child communication style. The subjects were 236 - 5th and 6th graders of elementary schools in Daegu. The major finding were as follows: First, children's self-esteem was affected by father's child-rearing involvement, fathers parenting behavior and father-child communication style. Second, father's parenting behavior has great effect on children's self-esteem than any other variables. Third, children's school adjustment was affected by father's child-rearing involvement, fathers parenting behavior and father-child communication style. Fourth, father-child communication style has great effect on teacher adjustment than any other variables. father's parenting behavior has great effect on pee. adjustment than any other variables. father-child communication style has great effect on school education adjustment than any other variables. Father's child-rearing involvement has great effect on school rule adjustment than any other variables.

The affection-image is the close-up of the face with real connections in space-time, or with virtual conjunction, outside spatio-temporal co-ordinates. The close-up can carry its own space-time in background. with deframing and fragmentation, Space itself has left behind its own space-time connection and become any-space-whatever that is the affection-image. The elements of any-space-whatever are the shadows, lyrical abstraction, the colors, the disconnected parts, the empty space. Deleuze examines any-space-whatever through the close ups, fragmentation of space and de-framing in Dreyer and Bresson's cinema.

This paper deals with the λ-labeling and L(2, 1)-coloring of simple graphs. A λ-labeling of a graph G is any labeling of the vertices of G with different labels such that any two adjacent vertices receive labels which differ at least two. Also an L(2, 1)-coloring of G is any labeling of the vertices of G such that any two adjacent vertices receive labels which differ at least two and any two vertices with distance two receive distinct labels. Assume that a partial λ-labeling f is given in a graph G. A general question is whether f can be extended to a λ-labeling of G. We show that the extension is feasible if and only if a Hamiltonian path consistent with some distance constraints exists in the complement of G. Then we consider line graph of bipartite multigraphs and determine the minimum number of labels in L(2, 1)-coloring and λ-labeling of these graphs. In fact we obtain easily computable formulas for the path covering number and the maximum path of the complement of these graphs. We obtain a polynomial time algorithm which generates all Hamiltonian paths in the related graphs. A special case is the Cartesian product graph K_n☐K_n and the generation of λ-squares.

Let $G = Z_2$. Let X be any compact connected orientable nonsingular real algebraic variety of dim X = k = odd with the trivial G action, and let Y be the unit sphere $S^{2n-k}$ with the antipodal action of G. Then we prove that any G invariant entire rational map $f : x \times Y \to S^{2n}$ is G homotopically trivial. We apply this result to prove that any entire rational map $g : X \times RP^{2n-k} \to S^{2n}$ is homotopically trivial.

The theory for a novel fault-tolerant 4-active-pole homopolar magnetic bearing is developed. If any one coil of the four coils in the bearing actuator fail, the remaining three coil currents change via an optimal distribution matrix such that the same opposing pole, C-core type, control fluxes as those of the un-failed bearing are produced. The hompolar magnetic bearing thus provides unaltered magnetic forces without any loss of the bearing load capacity even if any one coil suddenly fails. Numerical examples are provided to illustrate the novel fault-tolerant, 4-active pole homopolar magnetic bearings.

The future information technologies and service paradigm will move from PC, the general purpose desktop computing environment, to the next-generation PC that provides information any where, any time, and any device. The next-generation PC such as wearable computers are specialized to the human-centric functionalities and always-on connected services. In this study, service infrastructure of wearable computing with WBAN(Wearable Body Area Network) was suggested for the ubiquitous computing environment.

속도가 느린 모뎀으로 데이터통신을 할 수 있다는 사실에 고마움을 느낀 게 바로 얼마전이지만 이제는 거리에서 게임을 즐기고, 차안에서도 주식시세를 확인하는 세상을 살고 있다. 더구나 유선과 무선으로 분리됐던 통신망을 단일망으로 통합하는‘NGN’에 이어 더 포괄적인 개념의‘BcN’구축사업이 본격화되고 있고, 곳곳에 컴퓨터 칩과 센서가 박히는‘유비쿼터스 시대’도 눈앞에 두고 있다. 언제(anytime), 어디서나(anywhere), 어느 기기(any device)든지, 미디어에 구애받지 않고(any media) 소통할 수 있는 4any시대가 열리고 있는 것이다. 이에 발맞춰 세계 유수의 기업들은 저마다 새로운 승부수를 던지고 있다. <디지털콘텐츠>는 2회에 걸쳐 인프라 변화추이를 살펴보고, 이에 따른 차세대 디지털콘텐츠 산업을 조망한다

본 논문은 심리음향모델과 주파수변환을 이용하여 MP3 와 AAC 의 압축에서 강인하게 살아남을 수 있는 디지털 오디오 워터마킹 알고리즘에 관한 것이다. 워터마크를 의사난수열이나 이미지 등 외부 정보를 이용하지 않고 원본음악으로부터 생성시킨다는 것이 본 논문의 가장 큰 특징으로 원본 오디오로부터 생성된 워터마크는 음악과 융합되어 워터마크의 삽입여부를 일반인의 청각으로는 인식할 수 없다.
