본 논문에서는 ATM Forum에서 제안하고 있는 LAN 에뮬레이션 서비스 구조를 소개하였다. LAN 에뮬레이션은 기존의 방대한 LAN 응용 소프트웨어들을 ATM 망에서 그대로 사용하기 위하여 ATM 망에서 기존의 비연결형 LAN 서비스를 에뮬레이트하는 MAC 계층 서비스를 제공한다. LAN 에뮬레이션에 의하여 ATM 망상에는 논리적인 오버레이 망인 에뮬레이트된 망이 형성되는데, LAN 에뮬레이션 서비스는 에뮬레이트된 LAN의 각 종단 시스템에 설치되는 LAN 에뮬레이션 클라이언트(LEC)들의 집합과 세 가지의 논리적 서비스 요소들로 구성된다. 이 세 가지의 논리적 서비스 요소들은 LAN 에뮬레이션 구성 서버(LE 서버), Broadcast and Unknown 서버(BUS)라고 불리우며, LF, 클라이언트는 이 세 가지 서버가 제공하는 서비스를 이용하여 기존 LAN과 ATM망과의 상호 연동 및 ATM 망에서의 LAN 응용간 투명한 통신을 지원한다.

When it comes to the architecture design, Kuma Kengo rejects a strong and violent subject-centered position and advocates the design that is object-oriented. As can be seen in 'gentle architecture', 'three lows principle', 'natural architecture', and 'connecting architecture', he clearly expresses the objective nature of architecture design in those terms. In this respect, the purpose of this study is to make a close inquiry into the meaning, effect and characteristics of objectivity. In particular, we try to identify the contents of 'impure architecture', which has a clear ambivalence to be an instrumental expression strongly settled in the objectivity, in an aesthetic standpoint. To do that, we systemized the concept of mimesis and the theory of subversive appropriation by Walter Benjamin and Theodor Adorno in to a frame of interpretation. By systemizing translation, subversion, verbalization and the dialectic structure of the aesthetics of negation, we interpreted the features of his works as an objective work and 'impure architecture'. His objectivity leads the situation by subversively appropriating the inherent elements of architectural conditions based on a dialectic solution in which inquiries on logical and scientific materials have played a critical role. Above all, through all these processes, he tried to suggest a language as a new technique for materials and structures. Ultimately, we could find out that this object oriented design sublates a subject oriented way that is monolithic and repetitive regardless of objects. Rather, it is a way that is effective in creating a new way of design by making a different approach to a new object rather unfamiliarly, yet deeply.

Since Adolf Loos' Ornament and Crime was released, ornament had been regarded as a vice in Modern architecture. In Post Modern architecture, the ornamental vocabularies extracted from the classical architecture have been symbolically expressed. As a result, the significance of existence of and the use value of architecture have increased with improved intimacy to the public. However, many studies that have analyzed architecture in terms of semantics and semiotics focusing on communication between architecture and the public have admitted instability in architectural meaning because of the fundamental difference between architecture and language. At the same time, the architectural representation has encountered a lot of limitations along with the deconstruction and non-presentation theory in Post-Structuralism. Even under these circumstances, the ornamental representation can be a critical factor which makes communication possible while expressing spatial identity in this pluralistic contemporary society. Hence, this paper has established logical grounds for research based on theoretical investigation on the concept of representation, semiotics, and ornamental representation, with regard to spatial communication through ornamental representation in commercial space. Based on Peirce's Semiotics which is the typical theoretical science in terms of representation, this paper has analyzed the three kinds of signs (Icon, Index and Symbol) that he proposed. Peirce's classification of signs becomes ideal when the factors are well balanced, with room for combination instead of strict classification. It appears that his theory of signs would be useful in understanding and analyzing ornamental representation. This study on representational ornament could offer a plan for ideal communication and abundant spatial experience in the interior design of commercial space in which the expression of creative space identity is required.

The purpose of this study is to analyze the interior characteristics of Philips Exeter Academy library by Louis I. Kahn. Kahn's main thoughts of 'what it wants to be ' and 'how it was done' play a important role in this research because these statements act as a clue to understand this library. 'What it wants to be' means the essence and existence of architecture and 'how it was done' shows the tectonic of architecture and construction process to enhance its presence. Most of his works inform that Kahn had consistently applied his thoughts into design process. The thoughts of the essence of library leads Kahn to configurate 3 layers of interior space. The emphasis of tectonic expression is also the characteristics of interior in that structure is the logical part of whole building system rather than concealing object for the exterior of buildings. In Exeter library, interior characteristics are summarized as 3 layers of interior configuration, the order in dynamics, the visualization of construction process, and the relationship between structure and space.

As wind power farm (WPF) installations continue to grow, monitoring and controlling large-scale WPFs presents new challenges. In this paper, a hierarchical network architecture is proposed in order to provide remote monitoring and control of large-scale WPFs. The network architecture consists of three levels, including the WPF comprised of wind turbines and meteorological towers, local control center (LCC) responsible for remote monitoring and control of wind turbines, and a central control center (CCC) that offers data collection and aggregation of many WPFs. Different scenarios are considered in order to evaluate the performance of the WPF communications network with its hierarchical architecture. The communications network within the WPF is regarded as the local area network (LAN) while the communication among the LCCs and the CCC happens through a wide area network (WAN). We develop a communications network model based on an OPNET modeler, and the network performance is evaluated with respect to the link bandwidth and the end-to-end delay measured for various applications. As a result, this work contributes to the design of communications networks for large-scale WPFs.

The purpose of this study is to analyze the characteristics of structural expression in the works of Louis I. Kahn. Kahn's main architectural thoughts of 'what it wants to be' and 'how it was done' are important in this research because these statements act as a clue to understand the relationship between structural expression and space. 'What it wants to be' means the essence and existence of architecture and 'how it was done' shows the tectonic of architecture and construction process to enhance its presence. Kahn's emphasis of structural expression stems from the fact that structure is the logical part of whole building system rather than the concealed object for the exterior of buildings. Therefore structure of Kahn's architecture is not a structure only to support building but a mean to express his thoughts in a corporeal way. In Kahn's works, the characteristics of structural expressions are summarized as the visualization of the order in dynamics, construction process, spatial system, and the relationship between structure and light in the space.

The increasingly high prices for oil, the exhaustion of fossil fuels as well as concern about global warming are driving rapid growth of alternative sources of energy in the world. The active solution for global environment and exhaustion of energy sources is to develop and popularize the technologies to use natural energy such as sunlight, wind, and water. PV(Photovoltaic) modules are efficient devices that has been considered a logical material for use in buildings. Recent advanced BIPV(Building Integrated PV) technology have rapidly made PVs suitable for direct integration into construction in the world. Recently, building has been higher and higher. Tall buildings have many advantages for BIPV such as wide facade area and no shading effect by the surrounding buildings. However. BIPV has not been applied for tall building facade yet. Therefore, the purpose of the research is to develop suitable BIPV for tall buildings and to put these technologies to practical use. Therefore, the purpose of the study is to investigate unification of BIPV to curtain wall to apply BIPV on tall building through research into advanced application of overseas BIPV cases.

Geomancy(風水, Fengshui in Chinese) is a geographic idea of the Orient that studies a piece of land(a site) to pursue the healthier and more comfortable life for people seeking a harmony with nature, and also, a practical science. Among the theoretical systems of the traditional geomancy handed down by the scriptures, the compass school(理氣論) makes researches into mountains, winds, the currents and amount of water circulation by using luo-pan(羅盤) for finding spot(穴), and it has been considered that it is the objective and logical analysis system of natural environment of selecting a good site by dividing the vitality of the ground into 12 levels of natural circulation principles and judging its direction by means of 88-direction method. In this context, researcher optimized the logic of 88-direction method by the 12-circulation system(胞胎法) of the compass school on the basis of directional theory, then after, using GIS analytical tool, researcher performed comparative analysis between the results from land suitability analysis of the subject site and the resulting value of the directional method in geomancy. The results therefrom indicated that more flexible directions and site could be chosen by applying 88-direction method. For the future research, it is required to apply wider variety of variables to the field study and more careful review of the case study with a focus on the 88-directiont method.

Cyber powers around the world are conducting cyber information-gathering activities in cyberspace, a global domain within the Internet-based information environment. Accordingly, it is imperative to obtain the latest information through the cyber intelligence preparation of the battlefield (IPB) process to prepare for future cyber operations. Research utilizing the cyber battlefield visualization method for effective cyber IPB and situation awareness aims to minimize uncertainty in the cyber battlefield and enable command control and determination by commanders. This paper designed architecture by classifying cyberspace into a physical, logical network layer and cyber persona layer to visualize the cyber battlefield using BGP archive data, which is comprised of BGP connection information data of routers around the world. To implement the architecture, BGP archive data was analyzed and pre-processed, and cyberspace was implemented in the form of a Di-Graph. Information products that can be obtained through visualization were classified for each layer of the cyberspace, and a visualization method was proposed for performing cyber IPB. Through this, we analyzed actual North Korea's BGP and OSINT data to implement North Korea's cyber battlefield centered on the Internet network in the form of a prototype. In the future, we will implement a prototype architecture based on Elastic Stack.
