Recently, as emotional elements have been applied to many fields including marketing, architecture, and design, new understanding on and interest in sensibility are emerging. The sensibility, as opposite meaning to the reason, has been excluded from academic object, and researches in sensibility have been diversified for the meaning, scope, application methods and even application target of sensibility without consistency. This study aims to redefine meaning of sensibility by examining documents related to sensibility, and to examine the features of sensibility in design, especially in space design. Consequently, sensibility was defined to function as a filter which deals with numerous stimulative informations intuitively and uniformly while human gives significance to a stimulus. According to the examination on apparent features of sensibility and studies of sensibility engineering, the sensibility occurs not only by visual and physical stimulus but also by meaningful stimulus, and both are known to have mutual influence on each other. In space design, spaces of many purposes can be categorized into the spaces of routine and out of routine following the empirical time, and physical stimulus and interesting factor pursued by these spaces are inversely proportional. This study is meaningful insofar as it enabled to explain interaction between physical stimulus, meaning, and other factors within sensibility as a comprehensive concept by redefining its concept.

In the swirl of change in the world, Media, the development of information technology, and the enterprise-oriented capitalism have tied the world as one unit, and have entered the period of adaptation. With the view of introspection of these concepts, this paper is mainly written by the theory of "matter as the content" with exploration of the design of essence and scientific approach. The design process is the condensational process which is developed by the exchange of reason and sensibility. This process, which is characterized by the objective manipulation of a given condition and the intervention of extrapolation, is the new way of thinking and approach rather than the concept of the way and means. The research of this paper is based on paintings and the analysis of essential experiments in design, the definition of the terms of content in the view of philosophy and design, and the analysis of the cases in architecture and spacial design. As a result, this paper shows that these designs are not just "Simulacre" but the essential eidos, and "content" is the core of these designs which can produce prototype as machine. Also, these designs can relatively be the persuasive methodology for the reflexive modernization.

In the development of large complex assembly, most design changes are from the following reasons.: 1) insufficient consideration of assembling sequence of downstream process. 2) interference and fit-up of related parts. 3) initial design changes which are not completely resolved. In order to reduce the first reason of above, the assembly-centric modeling methodology was proposed in the part (1) of the thesis. In this part (2), a Digital Mock-Up system, which is a tool to build a virtual mock-up in design stage, has been developed in order to prevent the other two reasons. The system can build a virtual assembly in various ways as followings.: 1) assembling parts which are located in user defined envelope. 2) assembling parts with the specified disciplines. 3) assembling parts that are selected in the part list. It can also make an assembly by the combination of above methods. In addition to that, it has the functions to read/write the virtual assembly and to explode parts of the assembly in desired direction. With the virtual assembly, engineers can design interference free parts without making physical mock-up. The system has been implemented with Oracle database management system in CATIA environment.

Creativity is considered very important in the intelligence-based and informationalized society in which changes and competition were premised. This phenomenon has appeared in the entire society and especially in design area, the development of creative design is needed. It is the reason that a designer must have an interest in design expression techniques which can be an assistance to express creative ideas and develop it. Under this circumstance, this study was to explore utilizations of the SCAMPER which is one of most useful techniques for expressing and developing creative ideas. Based on the results of the questionnaire research regarding creative expression techniques and trends in utilization of SCAMPER in visual design process, the study sought new possibility of utilization of SCAMPER. The result of the study showed that checklist of SCAMPER was classified and organized to expression of ideas and every steps of development.

This thesis is a study on behavior for anchorage zone in prestressed double T beam using strut-tie model. Stress conditions of Anchorage zone in prestressed double T beam are very disturbed because large concentrated forces act on relatively small areas. Hence, anchorage zone must be considered in Design of prestressed double T beam. If irrational design or irrational construction be conducted, that may lose stability in capacity as structure. In current design practice, certain parts of structure are designed with extreme accuracy, while anchorage zone in prestressed double T beam is designed using common sense, and experience. Therefore, it is generally very conservative. For that reason, logical, reasonable concept and accuracies are desired at design of anchorage zone in prestressed double T beam. Strut-tie method satisfies those desires. In this thesis, anchorage zone in prestressed double T beam is analyzed by considering prestressing forces. Strut-tie model is constructed based on principle stress trajectory obtained from 3D-finite element analysis in anchorage zone, and amounts of reinforcement be obtained. Results of analysis are compared with the way used in current design practice, and this thesis presents that strut-tie model can be an economical design than current design methods without losing the degree of safety.

In modern society industrial structure is being altered in complex and various way owing to rapid technical development and economic development, and concerns and recognition for surrounding environment is being moth heightened. For this reason, modern people requite the environment which can be applied in more pleasant and convenient way, and in order to satisfy such requirements, importance of the interior design mote vividly stands out, and concerns or the society for the design is being more Heightened these days. Especially, as for the design of the office space, the study transforming the office, which is the rendezvous of the information, into the business environment with more comfortable and sensitivity, being free rrom the design concentrated on the business efficiency and economic feasibility, has been actively proceeded. As it is the reality that various and new types of the business spaces have appeared, new office landscape design is requited as the device to solve the matter related to the society change. It is purposed to propose the office space which is comfortable together with flowing sensitivity by applying the color plan that unconsciously controls the human sense through remodeling of mid size of the office space.

Underground constructions continue to provide challenges to Geotechnical Engineers yet they pose the best opportunities for development and deployment of advance technologies for analysis, design and construction. The reason for this is that, by virtue of the nature of underground constructions, more data and information on ground characteristics and response become available as the construction progresses. However, due to several barriers, these data and information are rarely, if ever, utilized to modify and improve project design and construction during the construction stage. To enable the use of evolving realtime data and information, and adaptively modify and improve design and construction, the paper presents an analysis and design system, called AMADEUS, for underground projects. AMADEUS stands for Adaptive, real-time and geologic Mapping, Analysis and Design of Underground Space. AMADEUS relies on recent advances in IT (Information Technology), particularly in digital imaging, data management, visualization and computation to significantly improve analysis, design and construction of underground projects. Using IT and remote sensors, real-time data on geology and excavation response are gathered during the construction using non-intrusive techniques which do not require expensive and time-consuming monitoring. The real-time data are then used to update geological and geomechanical models of the excavation, and to determine the optimal, construction sequences and stages, and structural support. Virtual environment (VE) systems are employed to allow virtual walk-throughs inside an excavation, observe geologic conditions, perform virtual construction operations, and investigate stability of the excavation via computer simulation to steer the next stages of construction.

Performance and efficiency of hybrid (hydraulic-mechanical) pick-up device of deep sea manganese nodules collector are very sensitive to altitude and altitude of pick-up head relative to undulating seafloor. For this reason, motion control of pick-up head relative to the changing deep sea topography and other disturbances is of particular importance in design of pick-up device. The concept of design axiom is applied to a pick-up device of hybrid type. Kinematic analysis conducted in absolute Cartesian coordinates gives position, velocity, and acceleration of the hydraulic cylinders which enable the pick-up head to keep the preset optimal distance from seafloor. Inverse dynamic analysis provides the driving forces of hydraulic cylinders and the reaction forces at each joint. Design sensitivity analysis is performed in order to investigate the effects of possible design variables on the change of the maximum strokes of hydraulic cylinders. The direct differentiation method is used to obtain the design sensitivity coefficients.

This study aims to examine the background to the rise of Rei Kawakubo, a Japanese designer who achieved fame by suggesting the concept of deconstruction and recombination of clothes, and to look at environment of the time, the formative characteristics of her design and the Japanese aesthetic sense inherent in her design. As the method of research, collections that Kawakubo unveiled over the past 10 years starting in 2004 were examined, and a survey of the literature was conducted to describe the background of her growth and the Japanese aesthetic sense inherent in the design. According to the study, Kawakubo grew up in the ruins of a war, and went through a time of great tumult, when Western culture was mixing with Japan's traditional culture. She taught herself a method of creation involving the deconstruction of clothes, and their recombination. For this reason, her design from the beginning was inevitably focused on deconstructing clothes before they could be recombined. Through analyses of her collections, it was found that the formative characteristics of her design were characterized by asymmetry, incompleteness, humor and hybridity. Kawakubo created clothes under the influence of an ethnicity that was shrouded in individuality and a traditional aesthetic sense, and the formative characteristics of her design defined by asymmetry, incompleteness, humor and hybridity were closely related to the hybridity represented by Wabi (わび), Yugen (幽玄), Okashi (をかし) and Zakyo (雜居).

A damper is a hydraulic device designed to absorb or eliminate shock impulses which is acting on the sprung mass of vehicle. It converting the kinetic energy of the shock into another form of energy, typically heat. In a vehicle, a damper reduce vibration of car, leading to improved ride comfort and running stability. Therefore, a damper is one of the most important components in a vehicle suspension system. Conventionally, the design process of vehicle suspensions has been based on trial and error approaches, where designers iteratively change the values of the design variables and reanalyze the system until acceptable design criteria are achieved. Therefore, the ability to tune a damper properly without trial and error is of great interest in suspension system design to reduce time and effort. For this reason, a many previous researches have been done on modeling and simulation of the damper. In this paper, we have conducted optimal design process to find optimal design parameters of damping force which minimize a acceleration of sprung mass for a given suspension system using genetic algorithm.
