본 연구는 초등학교 수학에서 입체도형의 공간 감각에 해당하는 쌓기나무 단원과 관련된 공간 감각 요인들을 살펴보고, 이를 바탕으로 우리나라와 핀란드, 네덜란드 교과서의 입체도형의 공간 감각 관련 내용의 특징을 분석함으로써 앞으로 입체도형의 공간 감각 지도 개선을 위한 시사점을 제공하는 데 그 목적이 있다. 이를 위해 이론적 고찰을 통해 공간 감각의 의미와 하위 요인을 알아보고, 입체도형의 공간 감각과 관련된 공간 감각의 하위 요인과 활동 예들을 제시하고, 이를 기초로 우리나라, 핀란드, 네덜란드 교과서의 입체도형의 공간 감각 지도 내용의 특징을 분석하였다. 이론적 고찰과 교과서 비교 분석 결과 입체도형의 공간 감각 지도 개선을 위한 시사점으로 교육과정에서 공간 감각 요인의 포괄적 제시와 학년간의 연속성, 공간 시각화뿐만 아니라 공간 방향의 포함, 정신적 회전과 정신적 변형의 강화, 정신적 차원 변형의 다양한 방법들의 비교, 다양한 현실적인 공간 상황과 공간 대상의 활용을 제안하였다.

Tangible user interfaces have attracted strong attention in the HCI(Human and Computer Interface) community for their ability to take advantage of skills humans develop in the real world. We are developing "tangible media aided design system" which employs physical objects i.e., brick as interfacing media for 3D graphic modeling. This system is targeting for persons who are afraid of experiencing 3D graphic modeling and virtual space, or have a sense of reluctance in approaching to them. Our approach suggests the easiest way for people to experience computer system and virtual space carefree while developing and improving their space sense. This work is one of initial explorations of media aided design system using tangible user interfaces.

The space $BV^2_{\alpha}(I)$ of all the real functions defined on interval $I=[a,b]{\subset}\mathbb{R}$, which are of bounded second ${\alpha}$-variation (in the sense De la Vall$\acute{e}$ Poussin) on I forms a Banach space. In this space we define an operator of substitution H generated by a function $h:I{\times}\mathbb{R}{\rightarrow}\mathbb{R}$, and prove, in particular, that if H maps $BV^2_{\alpha}(I)$ into itself and is globally Lipschitz or uniformly continuous, then h is an affine function with respect to the second variable.

In this paper, we have use a fuzzy bitopological space (X, $\tau_1$, $\tau_2$) to create a family $\tau_{ij}^s$ which is a supra fuzzy topology on X. Also, we introduce and study the concepts of r-($\tau_i$, $\tau_j$)-generalized fuzzy regular closed, r-($\tau_i$, $\tau_j$)-generalized fuzzy strongly semi-closed and r-($\tau_i$, $\tau_j$)-generalized fuzzy regular strongly semi-closed sets in fuzzy bitopological space in the sense of $\check{S}$ostak. Also, these classes of fuzzy subsets are applied for constructing several type of fuzzy closed mapping and some type of fuzzy separation axioms called fuzzy binormal, fuzzy mildly binormal and fuzzy almost pairwise normal.

시각 커뮤니케이션 디자인에서 타이포그래피는 공간(평면)속에서 감추어진 '잠재적 태(胎)'이다. 타이포그래피에서 리듬을 보여준다는 것은 조형성을 가진 그래픽에 '미감'을 형성하는 것으로 그 표현방법이 매우 중요하다. 이러한 리듬이 시각적 흐름을 통하여 인지되어질 때 리듬감이 형성된다. 본 연구는 타이포그래피 작품뜩 통해 실증적 분석으로 시각적 리듬감의 새로운 유형을 제시한 것이다. 우선, 시각적 리듬감 형성을 기한 실험성이 강한 타이포그래퍼 필리포 마리네티, 로베르 마쌩, 볼프강 바인가르트, 데이비드 카슨 등을 연구의 대상으로 선정하였다. 시각적 이미지 특성 분석으로 어의변별척도(S. D. Scale)법을 사용하였고, 배리맥스(VARIMAX)로써 인자분석을 하여 시각적 리듬감의 유형을 도출하였으며, 다음과 같이 분류할 수 있었다. (1) 공감각적 리듬감(R-synesthesia)은 '청각의 시각화'와 '촉각의 시각화'를 통한 감각의 전이를 의미한다. (2) 동시적 리듬감(R-simultaneity)은 한 평면 안에 시간과 공간이 동시에 존재하는 것을 뜻한다. (3) 관계적 리듬감(R-connection)은 이질적인 요소들이 (한 평면 안에) 함께 공존하여 상호 관계적 역할을 하면서 전체적인 인상이 통일되어 나타나는 현상을 말한다. (4) 작가 중심적 리듬감(R-artist)은 작가가 내용을 주관적으로 해석하여 표현함에 다라 임의적, 계획적으로 독자의 시선을 유도하는 것을 의미한다. (5) 수용자 중심적 리듬감(R-reader).은 기존의 기독성을 탈피하여 수용자의 적극적인 참여로 형성된다.

This study intends to reconsider pleat, which was undermined as something too simple to express the details for women's costume, by focusing on the aesthetic value of plea in men's costumes in the west before the 20th century. Furthermore, based on the aesthetic value of the pleat, diverse studies on contemporary men's costumes shall help to attempt to set up a basis for the new mode of men's costume. The pleat, a component in the costume since the ancient times, had unique characteristics including functionality, a sense of volume, directing effect that is caused by line repetitions and formativeness that results through elasticity. First, the aesthetics of the pleat before the 20th century shows rhythmic sense through the repetition of the pleat line as shown in the drape type costume, and it also shows a sense of volume as the pleat is moved along the motion of the body. Second, it shows functionality as the expansion of space moves in accordance with the motion of body sets up an internal space of the costume that facilitates body motion. Third, the pleat extends two dimension space into three dimension space using its elasticity. It exaggerates specific parts of the costume while ignoring body shape in order to symbolize status and authority of men. Fourth, it unifies the costume by wrapping the body by using quadrangle cloths with drapers, and expanding the silhouette with the pleat artificially to conceal the physical character and personality of the wearer. The physical character of the wearer disappears into the space made by the pleat. The pleat reveals the voluptuous beauty within.

Across the culture of Western Europe, dichotomy based on the visual sense has evolved. They believed eyes and ears requiring a distance related in recognition, are more developed than any other human senses in human body. Dominant position, as a condition to using a perspective, the eye has been just concentrated in the development of optical sight. But developed a variety of modern media, highlighting the importance of the other perception, it makes dichotomy to the expansion of perception over the single function of visuality. Recently, Guille Deleuze and Merleau-Ponty try to recover the sense of tactility segregated in skin from body keeping eyes for distance. By the result, the activity can be happened by being connected to the body rather than to eye in the space between the subject and object. From the phase of recognition where the human body tries to identify the object in the space considering a time, it will be changed for the subject to the phase of structure vice versa. Visual tactility is to eliminate the distance between subject and object. If the visual tactility is to erase the distance different from the visual in dichotomy, it will be occurred to having a tension and makes new relationship to work trying to move the subjective point of view in object. Like this evidence in analysis of architecture, it can be easy to find the Korean architecture rather than western architecture in terms of emphasizing the time and space. The fact, architecture of Lee Dynasty had been preserved and consisted basic form and style over the centuries makes us assume that visual tactility was considered as well as the visual sense. This study will be intensive in terms of visual and tactile inherent in the subject and how it is being connected to the movement in the space and time.

in seaside was emphasized on mainly visual elements such as monumental sculptures, towers, landscape and so on. But a memorial space in seaside has peculiar and various sound environments comparing with other spaces. In that sense, there are many rooms to improve soundscape of the space by adding suitable sounds to or by subtracting unsuitable sounds from a memorial space.

This study aims to design soundscape of a memorial space with seaside view. So far, a memorial space in seaside was mainly emphasized on the visual elements such as monumental sculptures, towers, landscape and so on. But a memorial space in seaside has particular and various sound environments comparing with other places. In that sense, there are many rooms to improve soundscape of the space by adding suitable sounds or by subtracting unsuitable sounds to a memorial space

The $H{\beta}$ and some metal line indices, such as Mg2, Fe52 of single-age and single-metallicity populations are computed based on the method of evolutionary population synthesis, with careful consideration of the variation of the horizontal-branch morphology with metallicity and age. We find (a) that while metal lines are little af-fected, the $H{\beta}$ index is severely enhanced (up to 30%)by the presence of the blue horizontal-branch stars, frustrating the current age-estimations from this index with out careful consideration of these stars, and (b) that there is a systematic trend in the sense that the globular clusters in giant elliptical galaxies appear to be older than those in our Galaxy by several billion years. We also calculate these indices for the stellar populations with a metallicity spread, by adopting metallicity distribution functions predicted by chemical evolution models. The comparison of the models with the observed indices of the central regions of the early-type galaxies yields the results (a) that the ages of the giant elliptical galaxies would be older than the previous estimations by several billion years, and (b) that there is a considerable age spread among elliptical galaxies, in the sense that the giant elliptical galaxies are older than small ones.
