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.

Contemporary architecture is developing aspects of variety design in form and material. The various architectural trends even change classical materiality. This concept has the background of current idea - digital, information, imagination with paradigm. So this study aims to show the present status of the expressions in the contemporary architecture in Korea under its dematerialized situation. And like this, we know for study about the relation between dematerialization and current architecture, still more Korean present condition. In chapter one, the background, purpose and method of study are explained. In chapter two, this study inquires the general concept of dematerial. In the process of searching for the forming basic background this study understands the characteristic. In chapter three, this study inquires the aspect of dematerialized expression in modern architect. In chapter four, with characteristics drawn in chapter three, this study show the present status of the expressions in the contemporary architecture in Korea under its dematerialized situation. In chapter five, a synthetic conclusion is presented.

Nowadays, with progresses in robotic science, the design and implementation of a mechanism for human-robot interaction with a low workload is inevitable. One notable challenge in this field is the interaction between a single human and a group of robots. Therefore, we propose a new comprehensive framework for single-human multiple-robot remote interaction that can form an efficient intelligent adaptive interaction (IAI). Our interaction system can thoroughly adapt itself to changes in interaction context and user states. Some advantages of our devised IAI framework are lower workload, higher level of situation awareness, and efficient interaction. In this paper, we introduce a new IAI architecture as our comprehensive mechanism. In order to practically examine the architecture, we implemented our proposed IAI to control a group of unmanned aerial vehicles (UAVs) under different scenarios. The results show that our devised IAI framework can effectively reduce human workload and the level of situation awareness, and concurrently foster the mission completion percentage of the UAVs.

Through 1960 and 1970s, there had been constant endeavor in order to succeed the korean traditional architectural heritages. Among those efforts Ahn Yung Bae's book "Exterior Space in Traditional Korean Architecture"presented unique methodology utilizing abstraction of space and movement of subject. His method doesn't refer traditional form of architecture. He ignores formal elements. Instead, he reads space through subject's movement and this reading act creates meaning of space. So, he constructed knowledge not about the object of traditional architecture but the subject of today. Ahn's book opens new discourse based on traditional korean architecture. His analyses didn't deal with the form of traditional space, but the experiences of observer. However many historical documents related to architecture had not been interpreted until nineties and the succession of heritage became to be broken by modernity through 20th century. In this situation his book showed the unavoidable method, that is, the modernization of tradition.

This study is on the concept of Gunter Behnisch' s 'Situationsarchitektur'. Gunter Behnisch is known as the architect who have produced astonishing variety of different types of buildings since 1950s. His works always reflect his changing major concerns of architecture, which varied through his career such as flexibility and serial production in the 1960s, politics and place in the 1970s and 80s, and ecological issues in 90s and afterward. Behnisch says that the goal of architects' work is not so much the building as the situation to be created, and only such measures should be taken as in fortunate cases strengthen and give meaning to the situation that exists, or in less fortunate ones recreate it. The 'Situationsarchitektur' is realized through emphasizing transparency, humanity, public space, and open detail that could lead to a certain lightness and relaxedness in architecture not as an end in itself, but rather in the result. Architecture should be allowed to arise out of circumstances of use and construction, but form should not be imposed as a preconception. Also architecture should be strongly tied to time, space and local conditions. Behnisch tries to see the fundamentals of his work in such a way that subtlety and diversity develop of their own accord or are preserved as a reflection of a world.

Generally, there are many kinds of pumps used on a ship, which play an obbligato role to assist the ship's running. However, due to the pump's own motor, it becomes a main vibration resource that may cause serious problems in local. If the above situation happened, it may cause local resonance even structural damage. Also, the bigger the pump's size is, the more serious the vibration is. Therefore, it is very important for researchers to estimate the vibrations situation of pumps accurately and avoid or reduce the probability of resonance. Based on a real marine pump-HHG8065, this paper did a vibration analysis by FEM (Finite Element Method) and compared the results with actual test. Finally, it gave a discussion on the estimation of pump and provided an improvement way to the vibration level.

Transparency has been considered as a performance measure in bilateral teleoperation system. Therefore, many issues of transparency have been studied. This paper investigates the transparency in two-channel control architectures. At first, we show the feasibility using analytic transparency-conditions and present the two classes of two-channel control architecture, which are perfectly transparent under ideal situation. In addition, remedies to problems due to impedance model estimation errors under real situation are introduced. They are as fellows; design guideline of control parameters to reduce the effect of model estimation error effect and introduction of time delay estimation for unknown dynamics. From these analyses, the systematic control scheme, which is stable and well transparent under real implementation, is proposed in two-channel control architecture. Finally, the proposed scheme is applied to a 2 D.O.F master-slave system and the experimental results show the validity of the theoretical work.

The 'Research report on the Korean architecture(韓國建築調査報告)' is the first investigation and research of the Korean architecture by Japanese researcher. This paper is about Sekino Tadashi's viewpoints of Korean architecture in the 'Research report on Korean architecture'. And the findings are as follows. The investigation of the Korean architecture by Sekino Tadashi was carried out in the concern about the relation between Japanese architecture and Asian architecture, shortly after the research of the history of Japanese architecture started. And following investigation and research about Korean architecture by Sekino Tadashi was mainly focusing on the ancient architecture which he estimated highly in the 'Research report on the Korean architecture'. When he observed each architecture himself, he estimated highly the ancient Korean architecture, of course. And also he estimated highly many architecture of the Koryo and the Chosun period. However, when he estimated Korean architecture as a whole, he had been strongly influenced in the prejudice about Korea in Japan of those days. But this is not originate in his individuality. History research reflects the historical situation that the researcher was placed. The viewpoints of Korean architecture in the 'Research report on the Korean architecture' was produced by the Korean recognition in Japan of those days.

In the present architectural culture of Korea, the expression of Korean values and the contemporary trends of global architectures are not identified and arranged distinctly, so diverse tendencies are applied to the architectures of Korea recklessly. In this situation, minimal architecture is significant, which pursues the essence of architecture through the minimal materials. This thesis analyzes the characteristics of minimal architecture seeking after the essence of architecture by minimalization and examines Seung, Hyosang's architectures showing expressional traits similar to those of minimal architecture in the modem architectures of Korea, so this study can show the expressional characteristics and materials of minimal architecture. Nevertheless, it does not mean that all the Seung, Hyosang's works have the tendency of minimal architecture and that he has to be classified as a minimal architect, but it means only that the values and thoughts like the expressional traits of minimal architecture are seen in his architectural opinions! and works, which will be the subject of this study.
