In this manuscript, we show that the equality relations of the two assertions (ix) and (x) of [Theorem 2.11, p.p.224] in [3] do not hold in general, by giving a concrete example. Also, we illustrate that Example 6.3, Example 6.7, Example 6.11, Example 6.15 and Example 6.20 do not satisfy a soft semi $T_0$-space, a soft semi $T_1$-space, a soft semi $T_2$-space, a soft semi $T_3$-space and a soft semi $T_4$-space, respectively. Moreover, we point out that the three results obtained in [3] which related to soft subspaces are false, by presenting two examples. Finally, we construct an example to illuminate that Theorem 6.18 and Remark 6.21 made in [3] are not valid in general.

Every totally disconnected space is hereditarily disconnected. In this note, we provide an example of a hereditarily disconnected which is not a totally disconnected space. We further provide an example that not homogeneous space is the product of a totally disconnected and a connected.

In this paper, we establish common fixed point theorem for type(${\beta}$) compatible four mappings with implicit relations defined on an intuitionistic fuzzy metric space. Also, we present the example of common fixed point satisfying the conditions of main theorem in an intuitionistic fuzzy metric space.

The purpose of this study had started from trying to look for a new standard in new media era and sounding out possibility of perspective of digital poetry, and had been extracting interpretational elements based on characteristics of otology in digital poetics research in technical method. Through examination of many documentary records, we suggested interpretive elements of medial space based on meaning and the theory of digital poetics. We deduced three perspectives based on relationship between the basic thesis in poetics and interpretive elements of medial space. We used them as tool for analysis of example. We chose as an example that change of program in space is clear through connection of media and space in where new form of creation happens through digital instruments and chose article as subject to which digital technology is applied and had been since 2000, The result of this study is as following: First, epistemological analysis about a space of digital media in new media era requires poetical approach unlike aesthetic approach. We can endow creative action and creation process with significance and pay attention to technical method of manufacturing, stating appropriateness of perspective in digital poetics. Second, the justice of digital poetics and its basic thesis help derive analytic elements from medial space and study purpose of production, technical method, ontological characteristics, which are three perspectives of digital poetics. Third, it analyzed characteristics of example according to three perspectives above and we can analyze characteristics of spacial expression in space of digital media into potential, trans-active, and semiosis space. It would be possible through analyzing examples in digital poetic perspective to overlook new methods of design in 21th and various perspectives and possibilities of medial space design.

We introduce the fuzzy semiregularization space induced by a fuzzy topological space and investigate some properties of fuzzy semiregularization spaces. We give an example of a fuzzy semiregularization space that is not a fuzzy semiregular space.

In this paper, we present some new properties for p-biharmonic hypersurfaces in a Riemannian manifold. We also characterize the p-biharmonic submanifolds in an Einstein space. We construct a new example of proper p-biharmonic hypersurfaces. We present some open problems.

Version space는 목표 개념이 속성 값에 대한 제한조건의 연언(conjunction)으로 표현될 수 있는 귀납적 개념학습에서 가설공간을 표현하기 위해 사용된다. Version space의 크기는 속성 값의 수에 대해 지수적으로 증가하는데, 우리는 DNA 분자를 이용하여 version space를 표현하는 효율적인 방법을 제시한다. 또한 version space를 유지하기 위한 기본 연산과, 이를 DNA 분자를 이용하는 구현 방법이 제시된다. 또한 DNA 분자로 표현된 version space를 활용하여 새로운 example에 대한 분류를 예측하는 방법을 제시한다.

Vaughan proved that if X is countably compact, then the Alexandroff duplicate A(X) is acc. In this note, we give an example to show that the result can not be generalized to star-Lindelof spaces. Moreover, we give a positive result.

If there exists a fuzzy continuous function from a fuzzy topological space (X, T) onto the discrete fuzzy toplogical space with two elements, then the space (X, T) is fuzzy disconnected. However, the converse is not true at all. We introduce an example for this and suggest a sufficient condition for which the converse holds.
