연구자의 작품에 투영되어 있는 탈주체의 형상과 속성, 그리고 탈주 방식 등을 들뢰즈와 가타리가 사회 변혁의 방식으로 제시한 리좀적 사유에 연결시켜 살펴보고, 그것이 사회적으로 어떠한 의미를 내포하고 있는지 밝혀보았다. 연구자의 작품에 투영된 탈주체는 어떤 완성체가 아니며 언제나 변화와 생성을 전제하고 있는 질료와 같은 것이다. 이 탈주체는 유·무의식적 욕망이 존재한다. 이 욕망은 들뢰즈와 가타리가 모순된 사회 변화를 추구하는 등의 긍정적 속성을 지닌 생성의 욕망이다. 탈주체에 이 욕망을 배치하게 되면 탈주을 감행한다. 이 탈주 방식은 들뢰즈와 가타리가 제시한 리좀적이다. 이것은 모순된 것을 해체하고, 외부와의 연결·접속과 단절을 반복하면서 새로운 질서를 생성한다. 작품에 등장하는 리좀적 탈주체는 반복적 붓질을 한 색면과 결합된 오브제를 가변 설치하여 탈주하는 과정과 방식을 추상적으로 표현한 것이다. 이 작품에서 탈주하는 탈주체들의 목표는 존재자들의 가치와 자유롭고 창조적인 삶을 인정하는 공간으로 안전하게 착륙하는 것이다. 이 탈주체들은 드넓은 초원을 유동하면서 끊임없이 새로운 풍경을 생성하는 노마드이며, 모순된 사회에 저항하는 예술가, 문학가, 즉 들뢰즈와 가타리가 사회 변혁의 개념으로 제시한 전쟁기계와 거리의 열정을 만들며 새로운 가치와 정치를 창안·창조하는 니체의 아곤 개념과 연결된다. 이들이 추구하는 것은 기존 질서를 완전 해체하는 것이 아니며, 타자성을 인정하는 가운데 공존할 수 있는 공간을 희망한다.

The purpose of this study is to propose cognitive ecological effects of fractal patterns in space design. This study investigated the perception and cognition problems regarding landscape patterns showing fractal properties from the cognitive perspective instead of the traditional speculative approach. In particular, the researcher has verified that fractal geometry theory and fractal pattern concept provide insight in space aesthetic values and cognitive effects. Research results are as follows. First, most environmentally-friendly fractal urban forms provide cognitive connectivity. In particular, this space provides a positive emotional response and preference to humans and displays self-organized complexity. This study found that such complexity of space form has characteristics corresponding to parallel cognitive structures of the human brain. Simultaneously, the researcher suggests that the fractal landscape pattern is an alternative for stiff and homogenized modern space. Second, fractal patterns provide hierarchical connectivity within the brain through continuous difference and repetition. In particular, self-similarities of fractal patterns administer significant visual grouping and coherence in human perception. It can be determined whether scaling coherence facilitates easier organization in cognitive organization. Third, fractal patterns in space design provide the basic method for achieving the connection between concept, construction, and urban factors. As a result, the researcher has suggested that scale distribution of geometrical factors, such as fractal patterns, an be a design method to connect various space typologies.

The thermal rating of a conductor are maximum continuous current capacity and short time emergency current capacity. The overload operation for a faults have an effect on a conductor lifetime. Its time duration and overload level are limited to facility conditions of transmission lines. The short time emergency current capacity in KOREA observe the KEPCO's DESIGN RULE 1210, but its rules are not included to concept of an allowable short time duration. This papers are described to the calculation concept of short time emergency current capacity considering a time duration and an overload level. And we suggested a operation grouping and its maximum conductor temperature considering facility conditions - conductor lifetime, stability of connection points, conductor height above ground and clearance, in the operating and new T/L.

After the "Landscaping Law" was enacted in 2007 Korea, national and local governments has been responding swiftly by seeking various methods. Seoul Metropolitan City and other municipalities have established "Seoul Coloring and Systematization" project, which analyzes and extracts the humanities, humanities and natural environments in 2007 as an opportunity to recognize the importance of environmental color. However, it is necessary to slightly supplement the color scheme created by the observer's concept. In this way, you have to find the color of the environment in a city where real life takes place. The city's environmental color has the concept of "walking" as the basic human behavior. Because the average speed is 4km, it differs from that of a vehicle that travels more than 60km per hour. Also, most of the frontage zone is used except for special cases. Therefore the characteristics of the environmental color and frontage zone on the road side were concluded in this paper as Single Type, Connection Type, and Extension Type. In addition, the principle of environmental color of city was established by the change of texture according to space of time and the characteristics of urban scale, and new media characteristics were found in various interactions. The results of this study suggest an environmental coloring strategy for workability such as hue continuity, hue harmonization and integrated design.

Steven Holl is outstanding architect who has been applied his phenomenological thinking to his works. he has been reported that he had adhered to focus his interest on coherent phenomenological theme and sublimated his architectural concept succesfully. This study focuses on relationship how phenomenological concept has common ground with architectural parts and with the study on phenomenological application methodology of architectonics of Steven Holl. In the case of Holl, with the theme of sense and flesh, he molds phenomenologically sensitive space. His works contains coherent phenomenolgical concepts such as distrust of rationality, synthesis of consciousness, and qeustions of perception. The Methodologies of connection with environment(nature or bridge), regional values, placeness, light and time are considered in his works(books and architectural works) as anchoring, interwining and parallax for phenomenological process in his concepts. His methodologies of enlisted works contain many valuable concepts of phenomenological intuition and would be applicable to contemporary and future architecture for humanism.

this paper presents the concept of "mobile ATM', a proposal for third-generation (3G) mobile communication network infrastructure capable of supporting flexible evolution of radio technologies from today's cellular and data services towards future wireless multimedia services. Mobile ATM provides generic mobility management and QoS-based transport capabilities suitable for integration of multiple radio access technologies including cellular voice. wireless data, and future broadband wireless services. The architecture of a mobile ATM network is outlined in terms of the newly-defined "W-UNI" interface at the radio link and "M-UNI"and "M-UNI" interface which supports unified access for WATM and non-ATM mobile terminals through corresponding interworking functions (IWF) is explained. leading to an understanding of how different radio access technologies are supported by the same ATM-based core network infrastructure. Generic mechanisms for handoff and location management within the core mobile network are discussed. and related protocol extensions over the "W-UNI" and "M-UNI/NNI"interfaces are proposed. the issue of "crossover switch (COS)" selection in mobile ATM is considered, and a unified handoff signaling syntax which supports flexibility in COS selection is described. Typical signaling sequences for call connection and handoff using the proposed protocols are outlined. Experimental results form a proof-of-concept mobile ATM network prototype are presented in conclusion.

In this study, I grasped the actual conditions of folk exhibition hall in Chungbuk area. From this data I researched basically as the fundamental role of regional museum, eco-museum core center facilities, the connection with islanded and various inheritances, and central facilities whole area to the museum. And I could get following conclusion. First, on the studied result of folk exhibition hall in chungbuk area, it is not enough the activity of unearthing, collection, study etc. that is basic activity of the museum because the museum just permanently displayed historical contents of the area and simple life folk data. Second, add to existent museum concept and have to widen viewpoint to the museum which whole area is no roof, and utilize folk exhibition hall as the central facilities. Specially, there are a lot of difficulties to communicate information to visitors because of the absence of cultural heritance exponent. So a plan that local resident participate actively in museum activity may have to be considered. Third, the concept of inheritance limited in historical culture of area has to be widening by nature and industry etc. And we should keep up study that is the linked plan to scattered conservation remains, inheritance and tourist place in area.

Purpose: This study was conducted to analyze the potential customer's satisfaction for the concepts of smart audio features and utilize the results when developing the customer-oriented products. Methods: 16 different features were derived via the market research and professionals' interviews. The most satisfactory features were selected through "Kano model", the relative importance of Customer Satisfaction Coefficient, and respondents' preferences from 339 valid survey answers. Results: 15 out of the 16 features were categorized as attractive attribute. "'User Recognizing' and 'Strengthen Linking' groups", such as Auto connection with Smart-phone music player, Synchronization of TV & Audio, and Volume control situational awareness, were shown to provide higher satisfactions to those potential customers. On the other hand, Group 'Integrating Function', such as Aromatherapy and Auto lighting reaction, was shown to be relatively least preferred features. Conclusion: This study enabled which features could lead to the customer satisfaction. Nevertheless, it still requires extensive analyses in different countries and diverse cultures to target the global market. The audio product planners and R&D professionals are expected to learn useful information from such studies.

전나무의 천연갱신 형태를 임분의 특성과 연관하여 내설악 길골 총 30지역에서 조사하였다. 임학적 의미의 천연갱신은 주로 예전에 인공적 교란이 있었던 곳에서 나타나며 자연림의 특성이 강할수록 오히려 의미를 상실한다. 이것은 인공적 교란이 천연갱신에 더 나은 환경조건을 제공하기 때문으로 보인다. 이와는 달리 자연림에서 갱신단계는 인공림처럼 명확할 수 없고 잠시 나타났다 사라지는 상태이며 세대교체는 임분구조 변화의 일부라는 표현이 적합하다. 특히 patch dynamic이 임분구조를 결정하고 주 구성수종이 음수인 전나무 자연림에서는 인공림에서 사용되는 천연갱신 개념은 원천적으로 의미를 상실할 것으로 보인다.
