This paper is devoted to the study of the role of fuzzy proximity spaces. We define a fuzzy K-proximity space, a fuzzy R-proximity space and prove some of its properties. Furthermore, we discuss the topological structure based on these fuzzy K-proximity and fuzzy R-proximity.

We introduce the ${\kappa}_0$-proximity space as a generalization of the Efremovic-proximity space. We define a product ${\kappa}_0$-proximity and the quotient ${\kappa}_0$-proxmity and show some properties of ${\kappa}_0$-proximity space.

We introduce the $K_0$-proximity space as a generalization of the Efremovi$\check{c}$-proximity space. We try to show every ultrafilter in $K_0$-proximity space generates a cluster and every Cauchy cluster is a point cluster.

We introduce the $k_0$-proximity space as a generalization of the Efremovi$\check{c}$-proximity space. We try to show that $k_0$-proximity structure lies between topological structures and uniform structure in the sense that all topological invariants are $k_0$-proximity invariants and all $k_0$-proximity invariants are uniform invariants.

In this paper, we define the concepts of commute proximally, dominate proximally, weakly dominate proximally, proximal generalized ${\varphi}$-contraction and common best proximity point in probabilistic Menger space. We prove some common best proximity point and common fixed point theorems for dominate proximally and weakly dominate proximally mappings in probabilistic Menger space under certain conditions. Finally we show that proximal generalized ${\varphi}$-contractions have best proximity point in probabilistic Menger space. Our results generalize many known results in metric space.

We will define the fuzzy quasi-proximity space and investigate some properties of fuzzy quasi-proximity spaces. We will prove the existences of initial fuzzy quasi-proximity structures. From this fact, we can define subspaces and products of fuzzy quasi-proximity spaces.

The purpose of this study was to examine the personal space by proximity of clothing to self. The scales used in this study include the scale of Nakane(1973) personal space the scale arranged on the basis of Sontag(1978's) study for proximity of clothing to self. The subjects of this study were 885 adult women in Taegu. The data were analyzed by using freqeuncy analysis {{{{ chi ^2 }} test and the Cronback $\alpha$ was also applied. The results of this study were summarized as follows : The results of this study were summarized as follows : It was shown that there was a high tendency that all those whose proximity of clothing to self is high It was shown that there was a high tendency that all those whose proximity of clothing to self is high or low sit opposite to the other persons or in a place where they can be seen well when they are well dressed with good make-up. but that all those whose proximity of clothing to self is high or low sit behind the other persons or in a corner seat or place where they can not be seen well when they are not well dressed with no make-up.

In this paper, we introduce the concept of the intuitionistic fuzzy proximity space as a generalization of a fuzzy proximity space, and investigate some of their properties. Also we study the relations between intuitionistic fuzzy proximity spaces and intuitionistic fuzzy topological spaces.

태그는 위치정보가 없기 때문에 리더의 식별자를 위치정보로 사용하지만 비연속적인 심볼형 정보이다. 따라서 태그 이동 궤적간의 근접성을 정의하는 것이 어려우며 사용자 질의 처리시 비효율적이다. 본 논문에서는 태그 위치를 표현하기 위하여 인식공간을 정의하고 인식공간 근접성을 제안한다. 인식공간 근접성은 정적 인식공간 근접성과 동적 인식공간 근접성으로 구성되며 이를 이용하여 태그 궤적 간의 근접성을 측정하고 효율적인 색인을 구축할 수 있다. 제안한 태그 이동 궤적 근접성 함수를 평가하기 위해 태그 색인 기법인 IR-tree와 이동체 색인 기법인 $R^*$-tree를 대상으로 성능평가 실험을 수행하였다.
