  • The effects of smear and well resistance should be taken into account for the design of sand drains. Practically, simple design, which employs the method using 112 reduced diameter of drains or assuming the coefficient of consolidation in horizontal direction equals to that in vertical direction, based on the theory neglecting these effects, has been used. In this study, the reliability of existing simple design methods as well as the influences of smear and well resistance was investigated with the equations proposed by Hansbo and Onoue. It is shown that the consolidation time is chiefly governed by the effect of smear for drains with highly permeable sands. For general soil condition and placing type of sand drain, consolidation time is underestimated for simple design wi어. 1/2 reduced diameter of drains, and it is overestimated for that with the assumption that the coefficient of consolidation in horizontal direction equals to that in vertical direction. Through the investigations on different reduced diameter, it was shown that simple design with 1/4 reduced diameter of drains yielded the reliable results with errors less than 6%.

  • The masonry structure has been widely used as the dwelling house structure in our country for a long time. The masonry structure is weak in the lateral forces such as strong wind and earthquake. But there is no regulation for it in the domestic aseismic design codes. The purpose of this study is to suggest a simple design method of un-reinforced masonry wall.

  • The purpose of this study was to prepare the visual communication tool, which would be used for the interior design consulation to reduce the communication gap between an interior designer and a client. To achieve the study purpose, review of literature, questionnaire survey, qualitative analysis and design research methods were used. The major results of this study were as follows: 1) "Image Cube" was designed as a comprehensive rule to classify interior image types. By this, eight interior image types were classified: SFU(Simple-Formal-Urbane), SFN(Simple-Formal-Natural), SCU(Simple-Casual-Urbane), SCN(Simple-Casual-Natural), DFU(Decorative-Formal-Urbane), DFN(Decorative-Formal-Natural), DCU(Decorative-Casual-Urbane), DCN(Decorative-Casual-Natural). 2) The Interior image collages were composed to present the overall feeling of each interior image type. 3) The Interior image models which would be used as the standard to be modified to various sub-types through the interior design consultation were produced corresponding to interior image types.age types.

  • A simple seismic design procedure for pile foundation using PAR and LPILE$\^$plus/ was proposed. A case of pile foundation under a simple bridge was selected and analyzed. The calculated horizontal movements, shear forces and moments were compared with those evaluated by the numerical exact solutions, and the farmers had similar trends with the tatters.

  • This paper describes Genetic Algorithm-Based Relay Search Method, RS-GA, which is developed in this study to search the multiple design variables in the design space. The RS-GA based on Simple-GA consists of some functions to search many variables from some wide variable space. It repeats a Simple-GA, that is the convergence process of the Simple-GA, which makes many time reiteration itself. From the results of the numerical studies, it was actually found that RS-GA can search all peak-variable from the 2D functions including 5 peaks. Finally, RS-GA applied for design-strengthening problems in composite plate girder bridges using the external prestressing technique is also verified.

  • Nendo, which was established in Tokyo in 2002, is a design company established by Oki Sato, which is gaining reputation as a new design group representing Japan through numerous design tasks encompassing diverse design sectors, such as architecture, interior, furniture, graphic, and products. This study was conducted to investigate the formative features of Nendo furniture by reviewing 133 pieces of Nendo furniture designed for the last ten years and identify the general characteristics of Nendo furniture by reviewing the time of launch, product launch type, and furniture type. As a result, the design features of Nendo furniture are as follows: First, the shapes of basic materials including boards, lumber, and bars are maintained intact and Nendo furniture has simple and moderate design without complicated or decorative elements. Second, Nendo furniture has simply embodied a design characterized by simple transformation, minimization of furniture elements, and rearrangement. Third, Nendo presents new and simple furniture differentiated from other pieces of furniture using optical illusions. Such expressions of optical illusions which are hardly found in preexisting furniture are a major feature of Nendo furniture. Fourth, a majority of chairs of Nendo cause optical illusions with the minimized size. In addition, their top boards made of transparent glass and mirror cause optical illusions with the properties of materials. In short, design of Nendo furniture is characterized by formative expressions, expressions of optical illusions, and differentiated use of materials. Fifth, Nendo keeps launching new furniture items in various exhibitions. As a result, Nendo makes furniture with its own unique characteristics based on its diverse studies and experiments which are applied to furniture design in a realistic way. In summary, design of Nendo furniture is characterized by simply embodied design based on small differences in daily life, minimalism with simple and moderate shapes, and its own witty uniqueness based on formative expressions, expressions of optical illusions, and use of materials differentiated from other furniture brands.

  • Conceptual system design of a multistage centrifugal air-compressor is the first loop of design procedure. The properly designed system is important for compactness, low manufacturing cost, easy controllability, fast extension for the new specification of the compressor. A simple procedure of conceptual system design is proposed in the present study using simple analysis. A few examples of the procedure for a real system are shown and several design aspects are discussed.

  • The purposes of this study were to identify styles of contemporary interior design, construct their images, and find out the relation of the identified styles to the structure images. Content analysis was used as the main method of this study, and the focus of the analysis was on a typological approach. Two hundred interior design photos were drawn from five different interior design magazines published in the past ten years, and ,they were analyzed by interior design professionals. Contemporary interior design was classified into ten styles: romantic, ethnic, classical, high tech, elegant, country, modern, minimal, natural, and causal. Given the ten styles, five images of interior design were identified - simple, comfortable, rustic, classical, and delightful. With regard to the relationships between 10 styles and 5 images of interior design, the this study found that the romantic style was related to the images of rustic and classical, the ethnic style to the images of comfortable, classical, and delightful, the classical style to the image of classical, the high tech style to the images of classical and rustic, the elegant style to the images of simple and classical, the country style to the images of comfortable and rustic, the modern style to the images of simple and delightful, the minimal style to the image of comfortable, the natural style to the images of comfortable and delightful, and the causal style to the images of comfortable and delightful.
