Entering into the 21st century, digital culture and the innovation of media technology have drastically changed our understanding of the concept of space. Increased availability of information made possible by technological advancement has, directly or indirectly, contributed to the development of space design, which, in turn, offers a possibility for a new paradigm in space design. Given these fundamental changes, this study seeks to explore how to understand the expansion of the concept of space. In order to answer this question, this study investigates de-materialization tendency in modern architectural design such as transparency, anti-gravity, complexity and simultaneity of space. It examines the interaction-oriented nature of space among human, information and time. Finally, based on concepts such as new hyper-surface, which transcend the limitations of space and time, it explores new emerging trends in space design.

The Monte Carlo tree search (MCTS) is a popular method for implementing an intelligent game program. It has several hyper-parameters that require an optimization for showing the best performance. Due to the stochastic nature of the MCTS, the hyper-parameter optimization is difficult to solve. This paper uses the self-playing capability of the MCTS-based game program for optimizing the hyper-parameters. It seeks a winner path over the hyper-parameter space while performing the self-play. The top-q longest winners in the winner path compete for the final winner. The experiment using the 15-15-5 game (Omok in Korean name) showed a promising result.

프로토타입 선택은 훈련 데이터로부터 클래스 영역을 대표하는 최소 데이터를 선택하여 낮은 학습 시간 및 저장 공간을 보장하는 장점을 제공한다. 본 논문은 모든 분류 알고리즘에 적용할 수 있는 초월 사각형을 이용한 새로운 훈련 데이터의 생성 방법을 설계한다. 초월 사각형 영역은 서로 다른 클래스 데이터를 포함하지 않으며 클래스 공간을 분할한다. 선택된 초월 사각형 내 데이터의 중간값은 프로토타입이 되어 새로운 훈련 데이터를 구성하고, 초월 사각형의 크기는 클래스 영역의 데이터 분포를 반영하여 조절된다. 전체 훈련 데이터를 대표하는 최소의 프로토타입 집합 선택을 위해 집합 덮개 최적화 알고리즘을 설계했다. 제안하는 방법에서는 탐욕 알고리즘과 곱셈 연산을 포함하지 않은 거리 계산식을 이용하여 집합 덮개 최적화 알고리즘의 다항 시간을 요구하는 시간 복잡도 문제를 해결한다. 실험에서는 분류 성능의 비교를 위해 최근접 이웃 규칙과 의사 결정 트리 알고리즘을 이용하며 제안하는 방법이 초월 구를 이용한 프로토타입 선택 방법보다 우수하다.

21세기 초반 스마트 혁명으로 시작된 4차 산업혁명으로 인해 우리 사회는 초연결(Hyper-Connectivity), 초융합(Hyper-Convergence), 초지능(Hyper-Intelligence)이 가속화되고 있다. 이런 변화는 시간과 장소라는 제한적인 공간을 물리적 공간과 가상적(디지털) 공간의 경계를 뛰어넘어 융합적인 새로운 공간으로서의 메타버스(Metaverse)를 만들어내고 있다. 메타버스는 1980년대 초반부터 1990년대 중반에 출생한 밀레니얼 세대(M Generation)와 1990년대 중반부터 2000년대 초반에 출생한 Z 세대(Z Generation)을 통칭하는 MZ세대와 맞물려 계속 확산되고 있다. 교회교육도 코로나19의 확산으로 예배로 모일 수 없을 때 메타버스를 활용한 다양한 시도가 있어고, 이를 통해 교회교육의 새로운 공동체 공간으로써 활용 가능성이 확인되었다. 그뿐만 아니라 메타버스를 교회교육에 활용하면 실제적이며, 체험할 수 있는 더욱 발전적인 교회교육 공간으로 활용될 수 있을 것이다. 그러나 교회교육이 더욱 발전하기 위해서는 공간적인 개념을 뛰어넘어 교회교육 방법의 발전이 필요하다. 특히 메타버스와 MZ세대의 공통된 특징 중에 하나인 사용자 중심성이 강조된 학습자 중심의 교육방법이 교회교육에 적용될 때에 메타버스 시대 속에 교회교육은 더욱 발전적인 방향으로 나갈 수 있을 것이다.

The rapid growth and influence of digital technologies have had a profound effect on modern society. Companies and businesses can connect through SNS(social network service accounts). The importance of mass media empowers the creation of virtual images that are more realistic than time and space. Unlike traditional reproduction or imitation, the virtual images created in this way are reproduced in a form that lacks the original inspiration's essence. Jean Baudrillard described this phenomenon as the theory of simulation. Baudrillard argued that imitated simulated images replace reality. He stated that reality is lost under excessive images in modern society. In response, based on an understanding of the theory of hyper-reality that emerged through the late stages of the order of simulacre, this study aimed to analyze modern fashion's method of reproducing hyper-real images and investigate the method's characteristics. This study examined the characteristics of hyper-reality described by Baudrillard and analyzed the method of artistic expression of hyper-reality. Based on this method of expression, reproducibility, following the stages of image simulation, was derived. A specific case applied to fashion was analyzed, and based on the image reproduction method, specific characteristics of hyper-reality characteristics in fashion were obtained. Sixty-four collections were selected, out of which 155 images and 43 brands demonstrated the principles of image transformation.

WBI provides new opportunities to realize the flexible learning environment based on hypermedia and to support distance learning with a diverse interaction. The instructors or learners in WBI claim to be able to resolve reluctant fluctuations such as disorientation and cognitive overload. To overcome these phenomena, a supplementary tool able to manage learning space organized by the instructor's or learner's own way and offer effective navigation techniques is presented in this paper. A learning space management and navigation tool called HyperMap dynamically represents the learning space in the form of a two-dimensional labeled graph. This HyperMap also can be used for an instruction design tool, learner's portfolio for the exchange of learning experiences. and the assessment of WBI.

The Support Vector Data Description (SVDD) has achieved great success in anomaly detection, directly finding the optimal ball with a minimal radius and center, which contains most of the target data. The SVDD has some limited classification capability, because the hyper-sphere, even in feature space, can express only a limited region of the target class. This paper presents an anomaly detection algorithm for mitigating the limitations of the conventional SVDD by finding the minimum volume enclosing ellipsoid in the feature space. To evaluate the performance of the proposed approach, we tested it with intrusion detection applications. Experimental results show the prominence of the proposed approach for anomaly detection compared with the standard SVDD.

The advent of various arts and remarkable development of mass media since 1980s accelerate fashion photographs' advancement. The expression of fashion through photographs can represent characteristics of ages, societies, cultures, traits of designers and techniques of photographers. In addition, that is the tool which contains economical role as a product and artistic role as photos. Therefore, this study examines hyprt-reality images in editorial fashion photographs. Hyper-reality means the reproduction which represents the reality of life more actually. Hyper-reality through photographs elevates reality of virtual things and creates the confused situation which haunts the boundary between reality and reproduction. This study classifies the hyper-reality in editorial fashion photographs into three groups by their external traits, ideal reality, collapse of reality, and restoration of reality. First, ideal reality is represented as harmony among fashion, characters, and space, causality of fashion with time and circumstances, positive will, and melting with nature. Second, collapse of reality is expressed as in harmony between fashion and situation, violence, fetishism and symbol of death. Third, restoration of reality is shown as recurrence to nature and images of utopia to express dignity of life.

This study starts from the question if the characteristic of existing conventional site-specificity can be applied to the modern city space in information media era as it is. The evolution and spread of media technology acted as the catalyst which establishes the identity of an individual and promotes the social sense of belonging as the new type of community member as well as expanded the communication territory of man. Moreover, as the perfect merge of third dimensional space with second dimensional media was accomplished, the meaning of city as the place is getting changed and extended to city space as the information platform which integrates and intermediates the various information composing city. Hereupon, this study is willing to analyze the limits which the characteristics of physical, active and meaningful elements which are the forming primary factors in the existing place theory have and establish the new meaning of city as the place through the case studies which are applied by the characteristics of hyper spacio-temporal, mobility and polysemy as the characteristics transformed by information platformization of city space.
