Recently, architectural design has been changing from formal design to freeform design due to the digitalization of construction industry. Especially, the formal design has been accepted as a design trend recently and applied many times as a design concept in the architectural design competitions such as turn-key. However, various deflects such as water leak and cracks have been occurred because the traditional construction methods had been applied without any revision or adaptation of the formal construction method for the freeform building construction. Therefore this research proposes location point control method for freeform metal panel installation which is focused on the application of LH JinJu new office.

This article is concerned with choice-based conjoint analysis versus rating-based and ranking-based conjoint analysis. Choice-based conjoint analysis has a definite advantage in that the respondent's task of choosing the most preferred profile from several competing profiles adequately mimics consumer marketplace behavior. It is crucial to design the choice sets appropriate for the choice-based conjoint. Thus, this article suggests a new method to design the choice sets that are well-balanced. It augments the balanced incomplete block design and then obtains the dual design of the result to accommodate various numbers of profiles. In consequence, the choice sets designed by the new method have the desirable characteristics that each profile is presented to the same number of respondents, and pairs of any two distinct profiles occur together in the same number of choice sets. The balancing of the design increases the efficiency of the conjoint analysis. In addition, the pair-comparison scheme can improve the quality of data through the identification of contradictory responses.

In this paper, we propose a new method to desing IIR Nyquist filters. By thismethod, we can design IIR nyquist filters which prossess linear phase characteristics andare lower in order than FIR Nyquist filters. WE derive expressions for zero-phased IIR Nyquist filters and propose new desing methods for them. An iteration process is used to design the proposed IIR Nyquist filter, and in each iteration step a modified version of the Remez exchange algorithm is used. Finally, the propose desing method is demonstrated through design examples.

We suggest layered sculpture method and color painting method with new materials for the preparation of various expressions for aesthetic model of the furniture and interior articles made of river birch. Through the analysis of the layered sculpture method and preference, we try to set a new direction for the enhancement of the decoration for the furniture or article design made of birch plywood. Also, we study the fittest manufacturing process after selecting color painting materials different from the existing painting method and goes well with the furniture or article made of river birch. Color painting which systemic application of the layered plywood from birch and new paints such as Oriental dye is one of the best schemes to realize various possibility of the furniture and wooden article made of the layered plywood, and this research result has affected positive effect on the development fields such as wooden furniture and interior articles.

This paper introduces a new combined method by genetic algorithm and random tabu search method as optimization algorithm. Genetic algorithm can search the global optimum and tabu search method is very fast in speed. The optimizing ability of new combined method is identified by comparing other optimizing algorithm and used for optimum design of damping plate.

This study analyzed the learning effect, through a satisfaction survey and NVivo qualitative analysis, of fashion design classes using humanities self-reflection writing. The results are as follows. First, with regard to learning satisfaction, learners perceived the class as efficient and showed overall satisfaction. Second, learners' opinions were classified into self-reflection writing, design process, new experience of expression, and the understanding of class activities. Third, in self-reflection writing, learners discovered their tendencies and values while exploring their identity through deep thinking. Fourth, in the design process, learners set the design concept consistently through writing. Fifth, in the new experience of expression, learners recognized the idea produced through writing as the result of thought and considered it a new expression method for design. Sixth, in the understanding of class activities, learners were interested in the process and considered it an activity through which to build their own style in design expression. Design class activities using self-reflection writing drew a positive response and presented the possibility of educational use. The teaching method of this study is expected to be used as a humanistic method for expressions in various design fields.

A new design method for the SCR-Chopper type speed controller of the battery-powered vehicles was developed. The conventional speed-controllers were either inductance type or contact type using resistance. In the new method, a photocoupler was used in sensing the control currents and a noncontacting type photo-conductive device (CDS) was used in mading acceleration. Experiments using these new devices showed encouraging results.

Recent the free-formed architecture is smearing as a trend with the development of the digital equipment and technologies. The development of new method based on digital technology is required for the free-formed structure,, because the conventional construction methods are limited to shorten the construction period and to ensure the construction quality. Particularly, the development of the new method for the free-formed concrete structure is important. In this study, the developed method of the T-shape lightweight steel fabricated using CNC can control the geometries of the free-formed concrete structure based on the digital design. Also, new method is effective to ensure the precision of the construction and economic than the conventional construction methods.

This paper introduces a practical determination method for soil parameters adopted in the new performance based design code for port and harbour facilities in Japan. In the new port-design code, the depth profile of the derived values is modeled as the profile of the estimated values so as to be either the mean value or the regression line, then the correction factors are multiplied to the estimated value according to the coefficient of variation (if COV > 0.1) and the number of the data entries (if n < 10). The new port-design code is applied to the unconfined compression test results for the Hiroshima Port clay in order to evaluate the undrained shear strengths. From the discussion, it is emphasized that not only the statistic treatment but also the engineering judgment are required in the procedure of the soil parameter determination for the reliability design.

In general, thickness of the sublayers under track is designed based on concept of vertical soil reaction value or vertical stiffness. However, this design method cannot take consideration into soil-track interaction under repetitive load, traffic condition and velocity of the train. Furthermore, the reinforced roadbed soils experience complex behavior that cannot be explained by conventional stress-strain relation expressed as soil reaction value k. The reinforced roadbed soils also can produce cumulative permanent deformation under repetitive load caused by train. Therefore new design method for the sublayers under track must be developed that can consider both elastic modulus and permanent deformation. In this study, a new design concept, a rule-of-thumb, is proposed as the form of design monograph that is developed using elastic multi-layer and finite element programs by analyzing stress and deformation in the sublayers with changing the thickness and elastic modulus of the sublayers and also using data obtained from repetitive triaxial test. This new design concept can be applied to design of the reinforced roadbed before developing full version of design methodology that can consider MGT, axial load and the material properties of the layers. The new design monograph allows the user to design the thickness of the reinforced roadbed based on permanent deformation, elastic modulus and MGT.
