Let X be a T-admissible space and A(x) be the set of all admissible fibers at x∈X. In this paper, we introduce some basic concepts, properties, and known results about set-valued maps, hyperspaces and especially T-admissible spaces. And then, we construct a certain set-valued map(Theorem 2.3) and an arc from {x} to X∈A(x) in use of the set-valued maps(Theorem 2.3 through Theorem 2.7).

In 1970's Goodykoontz gave characterizations of connectedness imkleinen and locally arcwise connectedness of $2^X$ only at singleton set {x} ${\epsilon} 2^X$ [5,6,7]. In [7], we gave necessary conditions for C(X) to be arcwise connected im kileinen at any point $A {\epsilon} C(X)$.

We study some relations between separability in fuzzy topological spaces and one in fuzzy hyperspaces. And we investigate some properties of axiom of countability in fuzzy hyperspaces.

Hypermedia systems allow the retrieval and representation of multimedia in- formation such as text, graphics, image and voice/sound using navigation and browsing mechanisms. In this study we developed a hypermedia system which provides hierarchical group, local map and cluster view for effective navigation in hyperspace. The system also supports hot link, reference link, move-to link and multiple link to browse the multimedia information space effectively. This system has been designed to integrate the navigation, browsing and searching function of the hypermedia system in hyman factor perspective and provides the user-friendly user interface mechanism.

In this paper we investigate relationships between closure-type and convergence-type properties of hyperspaces over a space X and covering properties of X.

In this paper we deal with the preservation of the periodic shadowing property of induced hyperspatial systems. More precisely, we show that an expansive system has the periodic shadowing property if and only if its induced hyperspatial system has the periodic shadowing property.

First, we investigate some properties of fuzzy compactness. Second, we introduce the concept of fuzzy local compactness in fuzzy topological space and study some of its properties. Finally, we investigate some relations between F-compactness in fuzzy topological spaces and one in fuzzy hyperspaces.

본 연구에서는 벡터 공간 모델과 HAL (Hyperspace Analog to Language)을 적용해서 단어 의미 유사성을 군집한다. 일정한 크기의 문맥을 통해서 단어 간의 상관성을 측정하는 HAL을 도입하고(Lund and Burgess 1996), 상관성 측정에서 고빈도와 저빈도에 다르게 측정되는 왜곡을 줄이기 위해서 벡터 공간 모델을 적용해서 단어 쌍의 코사인 유사도를 측정하였다(Salton et al. 1975, Widdows 2004). HAL과 벡터 공간 모델로 만들어지는 공간은 다차원이므로, 차원을 축소하기 위해서 PCA (Principal Component Analysis)와 SVD (Singular Value Decomposition)를 적용하였다. 유사성 군집을 위해서 비감독 방식과 감독 방식을 적용하였는데, 비감독 방식에는 클러스터링을 감독 방식에는 SVM (Support Vector Machine), 나이브 베이즈 구분자(Naive Bayes Classifier), 최대 엔트로피(Maximum Entropy) 방식을 적용하였다. 이 연구는 언어학적 측면에서 Harris (1954), Firth (1957)의 분포 가설(Distributional Hypothesis)을 활용한 의미 유사도를 측정하였으며, 심리언어학적 측면에서 의미 기억을 설명하기 위한 모델로 벡터 공간 모델과 HAL을 결합하였으며, 전산적 언어 처리 관점에서 기계학습 방식 중 감독 기반과 비감독 기반을 적용하였다.

The purpose of this study was to investigate how formativeness of shamanism has expressed and developed in modern fashion. Formative expression of shamanism in modern fashion has expressed in the way of on style, color, material and pattern as follows; Style has made animal and human incorporated by expressing abstract animal on the part or whole of costume and it has reconstructed traditional shaman costume into modern costume. Skin colors of living bodies which exist in nature, such as black, blown, yellow and grey, were used to symbolize spirit and low brightness of colors such as blue, white and black were also used to symbolize hyperspace. Artificial materials which imitate animal figure and genuine materials from animal were used. Various natural materials used in traditional shaman costume were also used. Animal patterns and abstract patterns symbolizing the celestial heaven and lower world, and patterns shown on wall painting and rock painting has appeared. The meaning of shamanism in modern fashion can be identified as interchangeable movement of time and space, a cosmic outlook on the world and ration. Spiritually designed costume has made fashion move to hyperspace in spirit trip. Modern fashion with shamanism has expressed its cosmic outlook on the world or universal wish beyond human's real world by patterns such as bird figure which means the celestial heaven and lower world. Corporation and transition of human and animal were symbolized as shaman hypernatural intercourse with designs expressed in costume using a part of animal or animal's characteristics.
