Adolf Loos and Hiroshi Hara are very well known for their distinctive method of spatial composition. Adolf Loos showed white silent outer facades from his strong aversion to the ornament, whereas dynamic and rich inner space by the principle called 'Raumplan' in his housing design. Hiroshi Hara, one of the most influential architects in modern Japanese architectural history, designed a series of controversial houses with radical design by his 'Yukotai Theory' and the thought of 'Reflection House'. Even they have no common in regional background or the period of their works, both similarly have shown their own focus on cladding surface as an important design language. From this point of view, this paper investigates the design method of those two architects focused on the similar points and also the differences of their approaches to cladding in housing design. In conclusion, in case of Adolf Loos, the cladding is a tool to create completely safe and pure inner space by separating from the outside. On the other hand, the cladding of Hiroshi Hara has the meaning of social ideology that individuals must follow the principles of a dominant structure, which is the reason why the cladding should be removed. However there exists something in common also. They radically denied the outer circumstances and had a firm belief that the requests from the inside living space were the more influential factors.

This study is aimed to investigate the characteristics of the elevations in the contemporary multi-family residential buildings in Paris. The survey was performed by studying 30 buildings which had won the multi-family residential project competitions, held in Paris in 2011. Since 30 buildings in the survey will be constructed in Paris in a couple of years, current trends of the elevations of the multi-family residential buildings can be extracted. Historically and also currently, in France, the multi-family housing has been studied to solve the various social problems; especially in Paris where the historical buildings and the modern and the contemporary buildings stand together in perfect harmony. The uniform elevations of the multi-family residential buildings in Korea, have been consist problems in the country. By studying the building elevations in Paris, the solutions to solve the current problems and to improve the situation, can be found. The study will be discussed in three different categories. First of all, the volume and the mass of building in the survey buildings, will be analyzed. Secondly, the openings in the facade, such as the windows and the balconies of the survey projects, will be analyzed. Finally, the materials and the colors of the facade will be discussed. By analyzing the elevations of the multi-family residential building projects, which had won the competitions, and are soon to be built in Paris, the various experiments and the attempts in building elevations, currently happening in Paris which is mostly known as a Haussmann style city, can be presumed, as well as the willingness of the city to reserve the historic buildings in the city.

The purpose of this study is to investigate the modernity characteristics of the traditional housing in Seoul 1920s to 1930s setting the criterion for analyses based on a Korean architect, Park, Kil-Ryong 'Housing improvement theory' about 'the Housing Plan of the Middle Area in Choseon'. The architect Park, Kil-Ryong expressed 'Housing Improvement Theory' positively founded on having a deep knowledge of traditional architecture. At his early working stage in 1928, he announced 'Housing Improvement Theory' about 'the Housing Plan of the Middle Area in Choseon' from the paper titled 'An Inquiry into the Housing of the Middle Area in Choseon', It is inferred that his paper quite affected the modern changes of traditional housing of those days. As the results of the study, even though the main floored room still keeps the symbolical and central position in traditional housing, the size of that is designed to be smaller than before. The room on the opposite side is generally designed widely as the scope more than 2 'KAN' and shows the features of expansion and division according to functions. By interchanging the location of the kitchen, the inner room as the main living space souths in the front of the house. The kitchen is designed as fitting size and separated from the space of working, linking, setting the table, keeping things and others. The bathroom is built in the house and then connected to the corridor. Each space is effectively planned for the best location in the house as considering lightening and ventilation.

This study investigated the application and the change of various architectural models by analyzing expression viewpoint media, which were applied to the visual information of digitalized 3D contemporary architectural models. The purpose of this study was to specify how modern architects have changed 3D architectural models to conceptual, logical, and formational visual information in the process of design. This study discovered a framework of analyses by theoretically investigating a relationship between expression media and expression change in the process of visualizing architectural models. Using the framework of analyses, this study analyzed how the expression viewpoints of architectural model information have been changed and applied. The transformation media of the visual information of digitalized 3D architectural models can be classified into conceptual, analytical, and formational information: 1) Contemporary architects used author-centered subjective viewpoints to express architectural concepts, which were generated in the process of their design. They selected a perspective viewpoint and a bird's eye view in order to present their architectural concepts and to depict them with one architectural model by expanding the visual scope of conceptual information. 2) Contemporary architects adopted observer-centered objective bird's eye view expression media to effectively present their architectural information to building owners and viewers. They used transformal media, which integrate architectural information into 3D and change it to different scales, in order to express their architecture logically. 3) Contemporary architects delivered model information about the generation and change of forms by expressing the image of a project from an author-centered viewpoint, instead of objectively defining formational information. They explained the generation principle of architectural forms via transformal media which develop and rotate an architectural model.

Modern microprocessors exploit instruction-level parallel processing to increase the performance. Especially VLIW processors supported by the parallelizing compiler are used more and more in specific applications such as high-end DSP and graphic processing. Bus-based VLIW architecture was proposed for these specific applications and it was designed to reduce the overhead of forwarding unit and the instruction width. In this paper, a optimizing scheduling compiler developed for the proposed bus-based VLIW processor is introduced. First, the method to model interconnections between buses and resource usage patterns is described. Then, on the basis of the modeling, machine-dependent optimization techniques such as bus-to-register promotion, copy coalescing and operand substitution were implemented. Optimization techniques for general-purpose VLIW microprocessors such as selective scheduling and enhanced pipelining scheduling(EPS) were also implemented. The experiment result shows about 20% performance gain for multimedia application benchmarks.

To project military power, the paradigm of the modern warship aquisition has evolved with more large platform and high-technology equipment. For example, the Aegis combat system equipped warship is one of the most advanced and capable defense systems currently in use. Concurrently, if the warship attacked and disabled, it may worse the asymmetry of the battle field and it also depress the morale of the fleet. For that reason, to keep and protect few number of the big and high technology equipped warship from enemy is very important. At the present, the performance of unit weapon has enhanced remarkably. A Korean-built SS-209 class submarine, Lee Chun-ham, participated in Naval Exercise Tandem Thrust conducted in 1999, sink the target ship ex-USS Oklahoma by a single torpedo. USS Stark was struck on May 17, 1987, by two Exocet anti ship missiles and disabled. For this reason, susceptibility should be prior to vulnerability and recoverability. In this paper, deception ship which is small and chief but has very similar signatures to large and high technology equiped warship has conceptually studied by using systems engineering approach. And it may be a effective way to enhance the susceptibility of the key fighting power.

The issues of generation, delivery, and processing of information which have been treated importantly in information design field have evolved along with the evolution of the humankind. In the modern society, the vast amount of, complex, and artificial forms of information such as big-data is accounted for the majority and claims of interest focusing on how to effectively design those kinds of information are being increased. This study explored the visualization methods applied with the natural objects as motives as one of the ways for users to easily get their perception and cognition to the information. Nature has long influenced on the human figural activities. The natural objects take the optimum visual shapes and provide the diverse inspiration and emotion to the designers in the various design fields such as product design, architecture design, and so on. Through the literature studies, we suggested the compositional principles of natural objects and the principles for observing and analysing natural objects as a principle to use the natural objects for information design domain. We, also, suggested the information design approach model which is inspired the natural objects by linking those two kinds of principles to the information design's visual realization factors and explored the possibilities of utilizing of the approach model by the case studies.

This research has conducted high availability system modeling to assure the reliability of shipboard combat systems. Shipboard combat system is a way for efficient execution of duty and a crucial battlefield management system that determines the outcome of battle in the modern war. Especially in regard to a network-centric operational environment in the future, even 1% of malfunction can lead to fatal consequences for the outcome of war. So combat system should be designed by high availability system which is a "always-on" service. In this point of view, This work describes an architecture-based various high availability model and proposed alternative high available systems that can achieve more than 99.9999% accuracy at a minimum. This paper also provides an applicable model with which system engineers analyze out system failure and recovery process by employing computerized tools.

Modern manufacturing industries is to produce both precise and robust mechanical parts without failure while they are in service. In order to prevent a part failure for its lifetime, a mechanical design for a part should be examined on a basis of mechanical simulation. A nozzle plate, being a key part in steam engines, changes flow directions of steam in a turbine used in power plant. This paper is to the design and test for part safety and durability. Currently, nozzle plates are fabricated by welding nozzles to their plates. Welding causes some defects on the used materials while they are being manufactured. Another major defect is un-even pitches between welded nozzles. Welding causes phase changes because of high melting temperature of metal. This leads to decay on the welding spots, which weakens their structural strength and then, may lead to early damages on mechanical structures. This research proposes assembly-typed nozzle plate without welding. From the beginning, nozzle and plate are designed for insertion-typed assembly. Nozzle head and foot are designed in accordance with the grooves on outer ring and inner ring of a plate to make mating surfaces. Then the nozzle plate should be proved for structural and fatigue safety before they are put in manufacturing. This research adopts commercial softwares for modeling and mechanical simulation. The test result shows that the design with smaller mating area and deeper insertion produces higher safety in terms of structure and durability. From the conclusion, this paper proposes the assembly-typed nozzle plate to replace the welding typed.

This paper considers the research content and its historical significance of the Study of Nature conducted by John Ruskin(1819-1900) who had a profound influence on art, architecture, social reformation, and preservation of natural environment in Great Britain. Because Ruskin's Study of Nature would be the key to understand totally the implicative meaning of his various academic trials for integrating a wider contexts among human, culture, and society, without being bound by the rules of conventional disciplines. For Ruskin, 'Nature' is defined as 'a system' governing every aspects of human and non-human beings, formulating certain laws of composition. This system has an ecological quality to form a state of harmony by internal interaction and process. Such organic quality of nature worked as 'a metaphor' in Ruskin's research practices. Therefore, Ruskin's Study of Nature would be the conceptual basis for organizing and connecting its various elements of Ruskin's spiritual world.
