This study analyzed expression types of dot patterns and derived out inherent characteristics to provide fundamental resources for advancement of high value added creative designs. As a result of the study, Firstly, the circular motive was used to form silhouettes or as a symbol of a decoration. Secondly, a simple form and color dot pattern was used to create one side, or a circular shaped accessory was used to be recognized as a construction line or a decoration line. Thirdly, textile printing is mainly used but handicraft and decorative images were used to add vitality through piece technique, embroidery, collage, cut-out, patch work, etc. Fourthly, different circular motives were integrated, partitioned and duplicated for abstract geometrical images. Fifthly, variations were added by mixing different dot patterns that are arranged regularly and irregularly in different sizes and gaps creating compounded designs with handicraft touches, different angles or on top of each other. Sixthly, hybrid images were created with rearrangement of dot patterns and by adding floral shapes, stripes or other abstract and geometrical shapes. Such various and creative attempts construct new formative beauty in fashion design and I believe that it can establish the development of unique images that satisfies the taste of today's consumers.

Jean-Charles de Castelbajac is gaining worldwide recognition as a designer who is not conscious of fashion and meet the desire of times. Castelbajac's works can be devided into three periods. 1. Creative challenge period. (1968~78) - His works started from creative challenge against haute-couture attract with practical design and extraordinary textile use. 2. Artistic development period. (1979~88) - He made unique ideas with the four primary colors affected by modern formative art. Pop-art clothes using cartoon or graffito were highlighted. 3. Aesthetic maturity period. (1989-now) - He received chevalier of Arts and the Letters at 1989. He was acquainted with other many designers in the world at 1990s, and his works came to mature. The aesthetic qualities in Castelbajac's works can be identified with the following themes. 1. Geometrical simplicity - Geometrical form without decoration and unnecessary lines used for the most comfortable cloth to wear and act gives an impression of explicitness and intelligence. 2. Humorous decoration - An unique idea having wit and humor shows his philosophy that must be new, vital and delightful. 3. Parody presentation - Pictures or people are reorganized 9Y work philosophy, then that get satirical and comic effects. 4. Pop-art image - Using mass communication media like a cartoon, figures, flag, graffiti, it produces clear and bright image.

Reliable and accurate method of computationally aided design processes of advanced thin walled structures in automotive industries are much essential for the efficient usage of smart materials, that possess higher energy absorption in dynamic compression loading. In this paper, most versatile components i.e., thin walled crash tubes with different geometrical profiles are introduced in view of mitigating the impact of varying cross section in crash behavior and energy absorption characteristics. Apart from the geometrical parameters such as length, diameter and thickness, the non-dimensionalized parameters of average forces which control the plastic bending moment for varying thickness has explored in view of quantifying its impact on the crashworthiness of the structure. The explicit finite element code ABAQUS is utilized to conduct the numerical studies to examine the effect of parametric modifications in crash behavior and energy absorption. Also the simulation results are experimentally validated. It is evident that the circular cross-sectional tubes are preferable as high collision impact shock absorbers due to their ability in withstanding axial and oblique impact loads effectively. Furthermore, the specific energy absorption (SEA), crash force efficiency (CFE), plastic bending moment, peak force responses and its impact for optimally tailoring a design to cater the crashworthiness requirements are investigated. The primary outcome of the study is to provide sufficient information on circular tubes for the use of energy absorbers where impact oblique loading is expected.

Yacht design is significantly affected by the hull geometrical characteristics. Therefore, it is necessary to closely examine the relation between hull and performance, before considering characteristics of sea condition. In this study, Genetic Programming is used to derive a formula the relationship between hull geometric characteristics and performance. Using the formula, a new guideline is proposed to determine performance of a yacht.

In this study, the room acoustics of a hall in Kimhae Performing Arts Center is discussed. The hall is designed as a multi-purpose hall. The reverberation time of the hall is varied by absorptive/reflective surfaces. A design method using both objective and subjective evaluations is investigated. As a result, the geometrical shape and the interior materials are determined.

The standing waves of the fourth bending ode of vibration and the first longitudinal mode of vibration were utilized to construct a ultrasonic linear motor. The geometrical dimensions of the vibrator were determined by Euler-Bernoulli theory. FEM(finite element method) employed to calculate the vibration mode of the metal-piezoceramic composite thin plate vibrator. ANSYS was used to design positions of the projections and calculate displacement of vibrator.

In this paper a useful method on evaluating the joint stiffness of bolted memeber was introduced using optimization technique on the basis of Finite Element Method. A finite element model having one directional gap element at bo undary area was introduced to compensate the prying force in jointed members which might caused by geometrical configuration of members. Results showed a good aggrement with classical method in certain range and will be available to definine the design margine of pre-load design.

This paper presents some proposed methods for discontinuum analysis with rock discontinuities data acquisited in tunnel design stage. The limit equilibrium method for rock block sliding and falling proposed in this paper can consider the tunnel excavation and support stage, and, to the extent, the standard deviations and means of joint set orientation. Simple Distinct Elemet modelling methods are recommended in estimating the stability of tunnels in jointed rock masses. Because, the simple models are likely to show more consistent and clear than very complex model with finite joint length and joint deviation parameters.

Danish Modern has been recognized as simple and comfortable design movement that was matched with its unique regional environment. There are various internationally well known designers such as Arne Jacobsen, Verner Panton. Danish Modern movement and International style had vital role to activate these designers' ideas and design quality. This paper aims to study the background and design characteristics of Danish Modern movement as well as some of the spatial projects by Arne Jacobsen. Furniture design of Jacobsen were already throughly studied in various researches. However his spatial projects such as architectural buildings and interior designs were not. This study analyzes three major architectural projects based on the four characteristics of Danish Modern: Formal Simplicity, Simple Functionality, Regional Contextuality, Reasonable Amusement. After the case study, this study discovered that Danish Modern characteristics had unique roles in the design process of Jacobsen's projects. Danish Modern is still valid design philosophy that can be applied to contemporary society.
