One of the characteristics of contemporary interior design is the prominence of material and its challenge to the established concept of interior design. As material has risen to the new element of design, losing its old concept as something secondary surrounding space, it had become an useful instrument to create unique images as well as to express the paradigm of space that modern society demands. The active role of material has made itself one of the primary elements that make a difference in design. Particularly in commercial spaces where sales are important and attractive spaces are needed, material has been emergent conveying its appling to consumers. Therefore, this study analyses the materiality that material has and its characteristics represented as images in commercial spaces. With the analysis, it researches further into the unlimited possibility of material and show the way for modern interior design to head for.

Worldwide plant market keeps maintaining steady growth rate and along with this trend, domestic plant market and its contractors also maintain such growing tendency. However, in spite of its external growth, win-win growth of domestic material industry that occupies the biggest share in plant industry cost portion is extremely marginal in reality. Domestic plant material suppliers are required to increase awareness of domestic material brand by securing quality and reliability of international standard through improvement of design quality superior to that of overseas material suppliers. Improvement of design quality of plant material becomes an essential element, not an option, for survival of domestic plant industry and its suppliers. Under this background, in this study, priority and importance by each evaluation index was analyzed by materializing plant design stage through survey of experts and defining evaluation index by each design stage and based on this analysis result, evaluation index of stage-gate based decision-making process that may improve design quality of plant material was suggested. It is considered that by utilizing evaluation index of stage-gate based decision-making process being suggested in this study, effective and efficient decision-making of project decision-makers would be enabled and it would be contributory to improve design quality of plant material.

The space can recognize by experience of sense, the each space to make identity through this. The contemporary architecture make possible an experience of sense through a complex paradigm and a composite concept expression. The material is not the assist to make a form, but to induce an image and an emotion of designers. The new material make possible the different design expression and the new aesthetic value. The appearance of difference material means the possibility to realize a designer's concept. The purpose of the study Is to analyze the new possibility of material expression through the study on material expression of interior design to associate the sense of being alive, to use basic data of the relation the material and the creativity. The study range is to define the sense of being alive, to image expression of material. It is to analyze the expression method of materials through to analyze the contemporary interior design. The expression method of materials to image the sense of being alive is direct and indirect and compromise. The interior design is visually to realize designer's concept, and the interior designer has to realize their it. The later study is on detail of material, in order to realize of material.

The goal of this study is to evaluate and design steel plates with optimal material distributions achieved through a specific material topology optimization by using a CCARAT (Computer Aided Research Analysis Tool) as an optimizer, topologically optimally updating node densities as design variables. In typical material topology optimization, optimal topology and layouts are described by distributing element densities (from almost 0 to 1), which are arithmetic means of node densities. The average element densities are employed as material properties of each element in finite element analysis. CCARAT may deal with material topology optimization to address the mean compliance problem of structural mechanical problems. This consists of three computational steps: finite element analysis, sensitivity analysis, and optimality criteria optimizer updating node densities. The present node density based design via CCARAT using node densities as design variables removes jagged optimal layouts and checkerboard patterns, which are disadvantages of classical material topology optimization using element densities as design variables. Numerical applications that topologically optimize reinforcement material distribution of steel plates of a cantilever type are studied to verify the numerical superiority of the present node density based design via CCARAT.

본 연구는 산업디자인에서 재료가 갖는 중요성을 살펴보고자 한 것이다. 제품계획이 디자인의 시작이라면 재료의 사용은 디자인을 완성시키는 마지막 단계라 말할 수 있다. 디자인 재료는 인류가 탄생되기 이전부터 존재해 왔으며 지금도 꾸준히 인간에 유용한 새로운 재료가 개발되고 있다. 우리 환경은 재료로 둘러싸여진 재료의 집합체라고 보아도 과언이 아닌데 재료는 물리적 특성과 함께 시·공간적이며, 문화적 특성을 지니고 있다. 또한 재료의 성질에 따라 각종 정보전달기능이 내포되어 있으며, 재료의 외부표면은 인간의 감각기관을 개발시키는 기능도 갖고 있다. 연구결과 나타난 디자인 재료의 4가지 문화적 특성을 살펴보면, 첫째 새로운 형태를 유도하는 기술적 진보 성, 둘째 커뮤니케이션 기능을 수행하는 상징성, 셋째, 표면효과를 개발시키는 감각적 속성, 넷째, 신소재, 신기술 등 미래를 확신시켜 주는 미래지향성 등이 있을 수 있다. 따라서 경재 력 있는 디자인을 수행하기 위해서 무엇보다도 재료와 디자인과의 조화. 구조와 가공, 그리고 재료가 갖는 실질적 의미를 파악하고 적절히 적용시키는 것이 중요하다. 왜냐하면 재료의 발견은 곧 미래디자인을 예측하는 척도가 될 것이기 때문이다.

This paper presents a systematic approach for estimating material performance of concrete mixture design based on satisfaction curves developed from statistical evaluation of existing or newly obtained material property related data. In performance based material design (PBMD) method, concrete material used for construction of a structure is designed considering a structure's specified performance requirements based on its usage and characteristics such as environmental conditions, structure types, expected design life, etc.Satisfaction curves express the probabilities that one component of substrates (i.e., aggregate size, cement content, etc) of concrete mixture will sustain different criterion value for a given concrete mixture design. This study presents a statistical analysis method for setting up concrete material parameter versus concrete criterion relationships in the form of satisfaction curves and for estimating confidence bounds on these satisfaction curves. This paper also presents an analysis method to combine multiple satisfaction curves to form one unique satisfaction curve that can relate the performance of concrete to a single evaluating value. Based on several evaluated mixture design examples for various material properties, the validity of the proposed method is discussed in detail.

This paper describes the design process of floor damping material optimization to reduce structure borne noise. This process uses finite element analysis(FEA) along with experimental techniques to complement each other. The objective of this approach was to develop an optimized damping material application layout and thickness at the initial design stage. The first step is to find the sensitivity areas of vehicle body without damping material applied using FEA. In order to determine the high vibration areas of the floor panel, the velocity was measured using a scanning laser vibrometer from 20 Hz to 300 Hz. To excite the floor panel vibration, shaker was placed at the front suspension attachment point. The second step is the optimization process to determine the light weight solution of damping material. The design guideline of damping material was suggested that the lightweight solution was verified using test result of road noise. Design engineer could efficiently decide the design variable of damping material using parameter analysis results in early design stage.

Material selection is one of the important activities in design and manufacturing. A selected material at the conceptual design stage affects material properties of the designed part as well as manufacturability and cost of the final product. Unfortunately there are not many accessible material databases that can be used for design. In this research, a web-based material database was constructed. In order to assist designers to compare different materials, two-dimensional and three-dimensional graphs were provided. Using these graphical tools, multi-dimensional comparison was available in more intuitive manner. To provide environmental safety of materials, the database included National Fire Protection Association publication Standard No.704. The web-based tool is available at http://fab.snu.ac.kr/matdb.
