In approach theory, we can provide arbitrary products of ${\infty}p$-metric spaces with a natural structure, whereas, classically only if we rely on a countable product and the question arises, then, whether properties which are derived from countability properties in metric spaces, such as sequential and countable compactness, can also do away with countability. The classical results which simplify the study of compactness in pseudometric spaces, which proves that all three of the main kinds of compactness are identical, suggest a further study of the category $pMET^{\infty}$.

The purpose of this study was to analyze the changes of floor plans in the entry and transfer spaces of single detached houses. The sample size was 185 households in Chungju, Jechon and Wonju Which are small cities in the central region of Korea. The results of the study are as follows: Firstly, the approach and transfer spaces show various changes and those are important factors which symbolize the housing plane typology transformations of the research areas. Secondly, the approach direction to the indoor space was more adopted a front approach in 1960's and 1970's, it is a side approach in 1980's, and a back side approach in 1990's. Thirdly, as the stage of the transfer space increased, the detached house planes have been changing to the direction, the depth of space comes to be deep, spatial function to be fixed, and privacy of bed rooms to be increased.

A notion of 'fuzzy' convergence of filters on a set is introduced. We show that the collection of fuzzy L-limit spaces forms a cartesian closed topological category and obtain an interesting relationship between the notions of 'fuzzy' convergence structure and convergence approach spaces.

Postmodernism, a cultural movement which occurred in the mid-20th century, avoided functional form, one of the features of modernism, and pursued post-rational and post-centric pluralistic thought which puts human emotions in importance. Postmodernism set a high value on emotional instincts of humans and focused on creation of empathy. It includes scepticism of rationalism and indicates the significance of emotional and psychological instincts of humans, or 'emotions'. Along with the big change in that time, more dynamic and unprecedented indoor spaces had appeared. Nigel Coates, who had taken various kinds of artistic activity from the early 1980s to the late 1990s, had tried to make a new approach of objet-focused emotional spaces. Such an approach made in the time when science and technology had rapidly developed and social structure had changed was considerably fresh, liberal, and futuristic. He interpreted spaces by escaping from realistic intentions and communicating with drawings, and designed object-focused emotional spaces by actively employing objets on the basis of ideas. He tried to make emotional sharing between the public and spaces through objet, and showed unique spaces in his own way by reinterpreting the meanings of spaces and stimulating human emotion. This study was intended to look into his artworks to show his way of approaching objets, and to find an application plan and the future possibility of the plan.

In this paper we introduce in study a new class of complex Finsler spaces, namely the complex Randers spaces, for which the fundamental metric tensor and the Chern-Finsler connection are determined. A special approach is devoted to $K{\ddot{a}}ahler$-Randers metrics. Using the length arc parametrization for the extremal curves of the Euler-Lagrange equations we obtain a complex nonlinear connections of Lorentz type in a complex Randers space.

In this paper, we prove the generalized Hyers-Ulam stability for the following additive-quadratic functional equation f(2x + y) + f(2x - y) = f(x + y) + f(x - y) + 4f(x) + 2f(-x) in modular spaces by using a fixed point theorem for modular spaces.

In this paper, we study the unicorn's Landsberg problem from an intrinsic point of view. Precisely, we investigate a coordinate-free proof of Numata's theorem on Landsberg spaces of scalar curvature. In other words, following the pullback approach to Finsler geometry, we prove that all Landsberg spaces of dimension n ≥ 3 of non-zero scalar curvature are Riemannian spaces of constant curvature.

지능형 협업환경에서 사용자가 원하는 서비스를 제공받기 위해 선행되어야 할 기술은 사용자가 원하는 협업기능 요구사항에 따라 협업환경 내 서비스들을 적절히 발견하는 서비스 발견(service discovery) 기술이다. 일반적인 서비스 발견과 관련하여, UPnP(universal plug & play) 의 SSDP(simple service discovery protocol)을 비롯한 여러 종류의 서비스 발견 기술이 존재하나, 지능형 협업환경이 요구하는 서비스 발견 특정을 만족시키기에는 일부 제약 사항이 존재한다. 이에 본 논문에서는 지능형 협업환경에서 제공되어야 하는 서비스 발견 기술의 요구사항을 살펴보고, 이를 만족하기 위한 방법으로써 다중 에이전트 시스템 (multi-agent system,, MAS)을 적용한 실용적인 서비스 발견 방법을 제시한다. 또한 지능형 협업환경의 일부 서비스에 제안된 방법을 적용하여, 본 접근방법의 타당성을 구현 결과를 통해 확인하고자 한다.
