The digital technology that has brought about the information revolution acts as the causes of multi-faceted socio-cultural phenomena. The spread of the digital environment and the popularity of the digital devices accelerate the phenomenon or the fusion of culture and technology, and such a phenomenon is no exception in the fashion design. Namely, the combination of fashion design and digital-based technology draws more and more attention; Not only the technology is simply applied to the fashion design, but also it is used as an emotional tool to enhance consumers' satisfaction, while some designs and marketing cases stimulating consumers' emotion are highlighted importantly. This study was aimed at surveying and analyzing the contemporary fashion using the digital technology and thereupon, assessing the characteristics of the emotional representations of technology as well as their aesthetic values. To this end, the theory of 'science of emotion and sensibility' was applied to divide the characteristics of emotional technological expressions in the contemporary fashion into immateriality, non-boundary, multi-media and interaction, while the aesthetic values of the emotional technology immanent in the contemporary fashion were categorized into communication & participation, conceptual configuration, physical expansion and variable movement. This study analyzed uses of technology for human emotion and sensibility shown in not only collections but also communication media and exhibition spaces and thereby, suggested the direction for our fashion industry to fulfill consumers' changing needs and advance further.

스마트 팩토리는 설계, 개발, 제조 및 유통 등 생산과정 전반이 디지털 자동화 솔루션으로 이루어져 있으며, 내부 설비와 기계에 사물인터넷(IoT)을 설치해 공정 데이터를 실시간으로 수집하고 이를 분석해 스스로 제어할 수 있게 하는 지능형 공장이다. 스마트 팩토리의 장비들은 게임과 같이 가상의 캐릭터가 하나의 객체 단위로 구동되는 것이 아니라 수많은 하드웨어가 물리적으로 조합되어 연동한다. 즉, 특정한 공동의 목표를 위해 다수의 장치가 개별적인 행동을 동시다발적으로 수행해야 한다. 공정 데이터를 실시간으로 수집할 수 있는 스마트 팩토리의 장점을 활용하여, 일반적인 기계 학습이 아닌 강화 학습을 사용하면 미리 요구되는 훈련 데이터 없이 행동 제어를 할 수 있다. 하지만, 현실 세계에서는 물리적 마모, 시간적 문제 등으로 인해 수천만 번 이상의 반복 학습이 불가능하다. 따라서, 본 논문에서는 시뮬레이터를 활용해 스마트 팩토리 분야에서 복잡한 환경 중 하나인 이송 설비에 초점을 둔 그리드 분류 시스템을 개발하고 협력적 다중 에이전트 기반의 강화 학습을 설계하여 효율적인 행동 제어가 가능함을 입증한다.

Design Problems are often both multidimensional and highly interactive. Very rarely does any part of a designed thing serve only one purpose. The activity of designing is thus a goal-directed activity and normally a goal-directed problem-solving activity. This means, problem solving is finding a way to get from some initial situation to a desired goal. Designers are transforming agents within a society whose goals are to improve the human condition through physical metamorphosis. Many theorist have agreed that designing involves problem solving or decision making. Accordingly evaluation plays an essential role in design activity. The evaluation factors include all attributes that have levels specified by quantitative and qualitative objectives Alternatives in multi-objective decision prOblems generally possess numerous attributes by which they can be described and compared. The evaluation factors include all attributes that have levels specified by quantitative and qualitative objectives. However since qualitative factors are difficult to quantify as numeral estimates, these factors have tended to be ignored without regard for their importance to human content. We adapted the Accumulative Evaluation Model as an evaluation algorithm for IDES. Industrial Design Evaluation System (IDES) consists of 3 major modules ( 1 Design Element, 2.Matrix, 3.Evaluation). It is intended to be an aid for design evaluation. The luther thinks IDES is a new design evaluation approach which could provide effective rating of design values to make value judgements. It is an attempt to provide industrial designers with access to design evaluation. The author's aim is to produce an Object-Oriented Evaluation System which can guide the designers and decision makers under complex design projects. It uses\ulcorner an Object-Oriented Programming for this prototype, Because of managing complexity (Flexibility and Reusability) and improving productivity(Extensibility & Maintainability and Programming by User) in software development process. The author has chose the C++ because it is a hybrid, rather than pure Object-Oriented Language.

The purpose of this study is to re-interpretate the meaning of place from the perspective view of events. In the realm of events, time, process, and evolution are emerging as more important elements for better places rather than space or fixed physical elements. First, this study reviews the phenomenological contribution to the meaning of place by discussing differences between positivism and phenomenology. The phenomenological approach has strengths that can perceive individual experiences and idiosyncraises through a holistic approach and qualitative methods. However, it has weaknesses such as unpredictability, subjectivity and ambiguity. In order to overcome these weaknesses, the notion of singularities(pure events) on the metaphysical plane existing between nature and culture is explored via Deleuzean concepts(Post-structuralism); singularities become events(simulacre) through ´becoming´ and these events have meaning through this process in the particular place. By this process, the subject an feed a sense of place through this meaning. Events unexpectedly create a series of events and have impact in the future. Creating various events in the particular place requires many contextural settings where the embodied perceptions could take place. Describing the potentiality of embodied perceptions demands ´smooth space´ rather than ´striated space´. Smooth space refers to the space where orientations and linkages are in continuous variation. Recent architectural and landscape architectural design projects reveal that the emphasis is placed on the open-ended set of various events unfolding over time rather than the physical settings of the place. For better landscape design, new concepts need to be introduced and implemented. These new concepts should focus on creating a series of events and considering the evolution of the place over time through multi-contextural and rhizomatical synthesis rather than rigid and static master plan of SAD(survey-analysis-design) methodology.

This research is to analyze the public cases of information facilities in terms of central circulations in multi level volumes such as atrium or court which provide visual intervention between different spaces and physical connections such as bridges. Hunt Library design balances the understood pre-existing needs with the University's emerging needs to create a forward-thinking learning environment. While clearly a contemporary structure within a traditional context of the NCSU campus, the Hunt Library provides a positive platform for influencing its surroundings. Both technical and programmatic innovations are celebrated as part of the learning experience and provide a versatile and stimulating environment for students. Public library as open spaces connecting to an interactive social domain over communities can provide variety of learning environments, or technology based labs. There are many cases of the public information spaces with dynamic networks where participants can play their roles in physical space as well as in the intellectual stimulation. In the research, new public projects provide typologies of information spaces with user oriented media. The research is to address a creative transition between the reading space and the experimental links of the integration of state-of-the-art technology is highly visible in the building's design. The user-friendly browsing system that replaces the traditional browsing with the virtual shelves classified and archived by their form, is to reduce the storage space of the public library and it is to allow more space for collaborative learning. In addition to the intelligent robot of information storages, innovative features is the large-scale visualization space that supports team experiments to carry out collaborative online works and therefore the public library's various programs is to provide visitors with more efficient participatory environment.

This paper presents a framework for controlling mobile multiple robots connected by communication networks. This framework provides novel methods to control coordinated systems using mobile agents. The combination of the mobile agent and mobile multiple robots opens a new horizon of efficient use of mobile robot resources. Instead of physical movement of multiple robots, mobile software agents can migrate from one robot to another so that they can minimize energy consumption in aggregation. The imaginary application is making "carts," such as found in large airports, intelligent. Travelers pick up carts at designated points but leave them arbitrary places. It is a considerable task to re-collect them. It is, therefore, desirable that intelligent carts (intelligent robots) draw themselves together automatically. Simple implementation may be making each cart has a designated assembly point, and when they are free, automatically return to those points. It is easy to implement, but some carts have to travel very long way back to their own assembly point, even though it is located close to some other assembly points. It consumes too much unnecessary energy so that the carts have to have expensive batteries. In order to ameliorate the situation, we employ mobile software agents to locate robots scattered in a field, e.g. an airport, and make them autonomously determine their moving behaviors by using a clustering algorithm based on the Ant Colony Optimization (ACO). ACO is the swarm intelligence-based methods, and a multi-agent system that exploit artificial stigmergy for the solution of combinatorial optimization problems. Preliminary experiments have provided a favorable result. In this paper, we focus on the implementation of the controlling mechanism of the multi-robots using the mobile agents.

시퀀스 매칭은 시계열 데이터베이스로부터 질의 시퀀스와 변화의 추세가 유사한 데이터 시퀀스들을 검색하는 연산이다. 기존의 대부분의 연구에서는 효과적인 시퀀스 매칭을 위하여 다차원 인덱스를 사용하며, 데이터 시퀀스를 이산 푸리에 변환(Discrete Fourier Transform: DFT)한 후, 단순히 앞의 두 개 내지 세 개의 DFT 계수만을 구성 속성 (organizing attributes)으로 사용함으로써 고차원의 경우 발생하는 차원 저주(dimensionality curse) 문제를 해결한다. 본 논문에서는 기존의 단순한 기법이 가지는 성능 상의 문제점들을 지적하고, 이러한 문제점들을 해결하는 최적의 다차원 인덱스 구성 기법을 제안한다. 제안된 기법은 대상이 되는 시계열 데이터베이스의 특성을 사전에 분석함으로써 변별력이 뛰어난 요소들을 다차원 인덱스의 구성 속성으로 선정하며, 비용 모델(cost model)을 기반으로 한 시퀀스 매칭 비용의 추정을 통하여 다차원 인덱스에 참여하는 최적의 구성 속성의 수를 결정한다. 제안된 기법의 우수성을 규명하기 위하여 실험을 통한기존 기법과의 성능 비교를 수행하였다 실험 결과에 의하면, 제안된 기법은 기존의 기법에 비교하여 매우 큰 성능 개선 효과를 가지는 것으로 나타났다.

The main objectives of this research are to compile all the researches published in the registered academic journals to study the trends of researches and analyze the relationships between research contents and the social factors so that the accomplishments of community related researches and future tasks can be identified. For this purpose, 97 papers published between 1973 and July 2011 were chronologically organized and analyzed in terms of research methods, main contents, and their relationship with social factors. The key findings are as follows; 1) Researches on multi-family-housing community started in 1973 mainly focusing on the social factors of neighbors in a complex; since 2000, however, the researches on physical factors were increased the most followed by psychological and social factors accordingly. 2) The research findings were not fully developed to give a guidance for appropriate space programs or an analysis of residents' preference on facilities. The cause of this shortfall is due to the fact that there was a lack of studies on residents' usage of community facilities based on quantified database. 3) More comprehensive researches should be conducted in the future for vitalizations of community through facility supply system and design guidelines, development and operation of community programs and measures to enhance community awareness targeted on public housing and more diverse types of housing being apart from typical multi-family-houisng provide by private sector.
