본 논문은 알미르 슈타트 극장 이후에 나타나기 시작하는 공간의 비위계적 구성(non-hierachical arrangement)으로 평면계획이 이루어진 SANAA의 작품들을 선정하여 공간구문론(space syntax)에 의한 정량적 분석을 시도하였고, 외형적으로 보여지는 평면구성의 비위계성이 정량적 수치값으로는 어떻게 나타나는지를 분석하였다. 분석결과 다음과 같은 결론을 얻었다. 첫째, 외형상 보여지는 비위계적 평면구성을 보이는 SANAA의 각 공간들은 정량적 수치값의 분명한 차이를 보이고 있으며, 외형적으로는 잘 드러나지 않는 공간의 위계 차이가 분명히 있음을 확인할 수 있다. 둘째, 통합도(Integration)값이 높은 공간들은 연결도(Connectivity)값도 대부분 함께 높음을 알 수 있었는데, 비위계적 평면구성의 위계성을 부여하는 방법으로 공간의 출입구 개수를 늘리거나, 실의 크기와 위치조정을 통해 숨겨진 위계성을 부여하고 있음을 알 수 있다. 셋째, SANAA는 그리드 형태의 평면구성에서 내부 복도 대신에 외곽부 복도를 이용하여 접근성 문제의 해결을 시도하고 있으며, 방과 방 사이의 오픈 코트 공간은 자연채광과 환기를 제공함과 동시에 공간의 숨겨진 위계성을 조절하는 장치로 채택되고 있음을 알 수 있다.

The problem of defining the relationship between interior space and exterior envelope of a building has long been a challenging task in the field of architecture throughout its history. This research chronologically reviews some of the important turning points in various schools of thoughts concerning construction of exterior envelope, with focus on how they influenced and altered the formation of our interior environment. This research also stipulates on how technological advance in the late 20th century laid grounds for a new type of interior-exterior relations in architecture through creation of flexible and ambiguous boundary conditions. The focus of this qualitative research will be on contemporary works of Japanese architects Toyo Ito, SANAA, and related group of architects who address the issues of transparency, flexible interior layout, buffer zones, structural facade, and neutralized (homogeneous) space that produces spatial quality of non-linear, non-hierarchical, and de-materialized space as a direct alternative to modern principles of space making.

In his non-hierarchical approach to art making, Robert Irwin questions how art is made. In the process, he seems to come down on both sides of the Modernism versus Postmodernism debate. Insofar as he wants to advance the avant garde tenets of modern art, he can be thought of as a modernist. But insofar as he denies Modernism's claims for transcendental status, he can be thought of as a postmodernist. Irwin's light and space environments, in particular, are conditioned by their basic attachments to their surroundings. They reveal the commonplace, but largely overlooked, richness of visual perception. By encouraging his viewers to open their eyes, Irwin wants them to engage in an act of looking, one that manipulates the basic syntax of seeing. This paper discusses Irwin's contributions to the art of his time (basically the transitional period between Abstract Expressionism and Minimalism) using as an example a light and space environment he created as the backdrop for the "First National Symposium on Habitability." This work was later reprised in 1980 as an independent installation. These works are examined to show how Irwin's art displaces modernist notions of authoritative (and authoritarian) quality with postmodernist ideas of direct (and demotic) value.

Because face has non-rigid structure and is influenced by illumination, we need robust face detection algorithm with the variations of external environments (orientation of lighting and face, complex background, etc.). In this paper we develop a new face detection algorithm to achieve robustness. First we transform RGB color into other color space, in which we can reduce lighting effect much. Second, hierarchical image segmentation technique is used for dividing a image into homogeneous regions. This process uses not only color information, but also spatial information. One of them is used in segmentation by histogram analysis, the other is used in segmentation by grouping. And we can select face region among the homogeneous regions by using facial features.

The purpose of this study is to investigate Seonyudo Park and Kkummaru in terms of haptic space. This is an attempt to escape from the limits of optical space that identifies the space with abstract concepts. Haptic perception of the space refers to feeling the space with all the senses through non-hierarchical interactions. Time of the haptic space is revealed by Deleuze's crystalline description and Bergson's pure recollection that is not useful to identify objects. According to two concepts, the running present forks into the past and the future, and the nature of time appears at the point of indiscernibility in which the past, present, and future coexist. Thought on time about the architecture provides a valid point of view to understand the relationship of visitor's sensory experience of space, recollection, and emotion. In this respect, it can be said that Joh sung-yong's two works explored for new areas of architectural experience by building up the potential image of the subject which is placed in the human memory. And then this study shows that two works recover the relationship between the past and the present so that they give an opportunity to consider the meaning of time in the architecture.

The variety of document ranking algorithms have developed to provide efficient mining results for user's query on the web environment. The typical ranking algorithms are the Vector-Space Model based on the text, PsgeRank and HITS algorithms based on the hyperlink structures and other several improvement algorithms. All these are for the user's convenience and preference. However, these algorithms are usually developed on then Horizontal and non-hierarchial web environments and are not suitable for the hierarchial web environments such as enterprise and defense networks. Thus, we must consider the special environment factors in order to improve the ranking algorithms. In this paper, we analyze the several typical algorithms used by hyperlink structures on the web environment. We, then suggest a configuration of the hierarchical web environment and also give the relations between agents of the web mining system. Next, we propose an improved ranking algorithm suitable to this kind of special environments. The proposed algorithm is considered both the hyperlink structures of the documents and the location of the user of the hierarchical web.

Non-manifold topological representations can provide a single unified representation for mixed dimensional models or cellular models and thus have a great potential to be applied in many application areas. Various boundary representations for non-manifold topology have been proposed in recent years. These representations are mainly interested in describing the sufficient adjacency relationships and too redundant as a result. A model stored in these representations occupies too much storage space and is hard to be manipulated. In this paper, we proposed a compact hierarchical non-manifold boundary representation that is extended from the half-edge data structure for solid models by introducing the partial topological entities to represent some non-manifold conditions around a vertex, edge or face. This representation allows to reduce the redundancy of the existing schemes while full topological adjacencies are still derived without the loss of efficiency. To verify the statement above, the storage size requirement of the representation is compared with other existing representations and present some main procedures for querying and traversing the representation. We have also implemented a set of the generalized Euler operators that satisfy the Euler-Poincare formula for non-manifold geometric models.

Background Phenomenography suggests that more variation is associated with wider ways of experiencing phenomena. In the discipline of mathematics, broadening the 'lived space' of mathematics learning might enhance students' ability to solve mathematics problems Aims The aim of the present study is to: 1. enhance secondary school students' capabilities for dealing with mathematical problems; and 2. examine if students' conception of mathematics can thereby be broadened. Sample 410 Secondary 1 students from ten schools participated in the study and the reference group consisted of 275 Secondary 1 students. Methods The students were provided with non-routine problems in their normal mathematics classes for one academic year. Their attitudes toward mathematics, their conceptions of mathematics, and their problem-solving performance were measured both at the beginning and at the end of the year. Results and conclusions Hierarchical regression analyses revealed that the problem-solving performance of students receiving non-routine problems improved more than that of other students, but the effect depended on the level of use of the non-routine problems and the academic standards of the students. Thus, use of non-routine mathematical problems that appropriately fits students' ability levels can induce changes in their lived space of mathematics learning and broaden their conceptions of mathematics and of mathematics learning.
