Exploring on two major questions: 'Why do we feel more love for certain objects?' and 'How can design use this knowledge to realize design sustainability?', this article presents an alternative way of approaching the problem of design sustainability from the perspective that our relationships with design objects are of an extended mode of social relations. Recent discussions on design sustainability have transformed the notion of the problem by seeing it as a problem of our basic perception of design objects and our relationships with them. In this light, I propose that design sustainability could not be achieved solely by approaching from a mechanistic perspective, but by re-framing the way we see and relate things around us and by supporting our changes and actions to move forward a more sustainable notion of our relationships with the objects. As a way to realize design sustainability, I propose that design should involve story-making quality that supports our initiatives to build more affectional relations with objects by seeing the objects as entities of communication that tell stories of us, thus reflect our identities and meanings of our lives. Proceeding on the exploration of the subject, I present some of conceptual outlines in forms of an image diary, an interplay-able furniture unit, and a performance instruction that suggest a way for a special story-making process and thus a stronger emotional tie with the objects.

최근 학습자 중심의 창의설계교육에 대한 관심과 요구가 급속히 높아지고 있으나 대부분의 대학에서는 아직 이를 위한 교과과정 및 창의설계실 등을 충실히 갖추고 있지 못하다. 본 논문에서는 공학교육에서 큰 관심을 모으고 있는 창의설계교육을 위한 설계중심의 교과과정 및 이를 수행하기 위한 종합설계실 구축 방안을 제시한다. 전자공학전공을 중심으로 기존 교과과정을 분석하고 이를 바탕으로 입문설계와 요소설계를 거쳐 종합설계로 이어지는 설계중심의 공학교육을 효과적으로 수행할 수 있는 새로운 교과과정 구성과 이 교과과정을 바탕으로 실무능력을 배양하기에 적합한 종합설계실의 구축 방안을 제시한다.

최근 객체 인식에 높은 성능을 가진 딥러닝 네트워크가 나오고 있다. 딥러닝을 이용한 객체 인식의 경우 성능 향상을 위해 학습 데이터 셋 구축이 중요하다. 데이터 셋을 구축하기 위해서는 이미지를 수집하고 라벨링 해야 한다. 이 과정은 많은 시간과 인력이 필요하다. 때문에 오픈 데이터 셋을 사용한다. 그러나 방대한 오픈 데이터 셋을 가지고 있지 않는 객체도 존재한다. 그 중 하나가 번호판 검출과 인식에 필요한 데이터이다. 이에 본 논문에서는 이미지를 최소화 하여 대용량 데이터 셋을 만들 수 있는 인조 번호판 생성기 시스템을 제안한다. 또한 인조 번호판 배치구조에 따른 검출률을 분석했다. 분석결과 가장 좋은 배치구조는 FVC_III, B이며 가장 적합한 네트워크는 D2Det이었다. 인조 데이터셋 성능은 실제 데이터셋의 성능보다 2~3%가 낮았지만, 인조 데이터를 구축하는 시간이 실제 데이터셋을 구축하는 시간보다 약 11배 빨라 시간적으로 효율적인 데이터 셋 구축 시스템임을 증명하였다.

Design is an iterative, generative, and multidisciplinary process by its nature. Iteration occurs often in most of the engineering design and development projects including construction. Design iterations cause rework, and extra efforts are required to get the optimal sequence and to manage the projects. Contrary to simple design, isolation of the generative iterations in complex design systems is very difficult, but reduction in overall iterations is possible. Design depends upon the information flow within domain and also among various design disciplines and organizations. Therefore, it is suggested that managers should be aware about the crucial iterations causing rework and optimal sequence as well. In this way, managers can handle design parameters related to such iterations pro-actively. There are a number of techniques to reduce iterations for various kinds of engineering designs. In this paper, parameter based Design Structure Matrix (DSM) is chosen. To create this DSM, a survey was performed and then partitioned using a model. This paper provides an easy approach to those companies involved in or intend to be involved in "design and build projects".

As AEC(architecture, engineering and construction) industry becomes larger and more complex, much information is going into each part and phase. Therefore, the existing building design process has to change and collaboration is emphasized among participants in various fields. The purpose of this study is to compare and analyze existing building design process and integrated building design process based on BIM using a IDEF0 methodology. And then, it establishes a desirable domestic integrated building design process application plan focusing on the design phase of domestic cases. As a result of analysis, flowing conclusions are included ; Firstly, problems occur on the existing building design process that are accomplished with focusing on the outcome. It makes much errors because of 2D-based information. Another problems is that collaboration doesn't go on smoothly. But, integrated building design process is accomplished with the collaboration and the coordination which pursues change and perfects cooperation. Secondly, BIM is a process of effecting optimum integrating, re-using information, and expense reduction throughout the life-cycle of a building. Moreover, it establishes a basis for the integrated building design process to build a collaboration system.

Recently three-dimensional (3-D) die design and production process has been widely introduced into the tooling shops of automotive manufacturers to reduce time-to-production of brand-new automobiles. 3-D solid models created in CAD systems are used not only for various simulations for design verification, but also for NC tool path generation to machine dies and their Styrofoam patterns. However, a lot of time and cost will be required to build solid models for dies if designers use only the generalized modeling capabilities of commercial 3-D CAD systems. To solve this problem, it is necessary to customize 3-D CAD system for the specific die design and manufacturing process. This paper describes a dedicated 3-D CAD system based on Unigraphics for die design for automotive body panels. The system provides not only 3-D design capabilities, but also standard part libraries, to enhance design productivity. The design process modeling technology has been introduced to facilitate redesign of the die for the modified panel. By introducing this system, dies can be designed more rapidly in the 3-D space, and their solid data can be directly transferred to CAM tools for NC tool path generation and simulation tools for virtual manufacturing.

As the demands for lightweight construction and precision grow, there is an increasing interest on hydroforming technology. This paper deals with designing automobile subframe for applying welded blanks hydroforming. In applying welded blanks hydroforming to automobile subframe, it is a serious problem that blanks wrinkle in deformed shape. To suppress wrinklings in blanks, the sections of the die where blanks wrinkled is modified. In addition to this, it is intended that the sum of thickness variation about wrinkling regions be minimized. For this purpose, parameters for influencing formability are selected and evaluated using orthogonal array. Among these parameters, parameters having a major effect on formability are selected again. Using CCD(central composite design) with the selected parameters, response surface is build up and optimal design is performed.

In this paper, a new design for an error correcting code (ECC) is proposed. The design is aimed to build an ECC circuitry with minimal power consumption. The genetic algorithm equipped with the symbiotic mechanism is used to design a power-efficient ECC which provides single-error correction and double-error detection (SEC-DED). We formulate the selection of the parity check matrix into a collection of individual and specialized optimization problems and propose a symbiotic evolution method to search for an ECC with minimal power consumption. Finally, we conduct simulations to demonstrate the effectiveness of the proposed method.

The aim of this study is to review the literature addressed the methodology to measure and evaluate the health outcomes as evidences for health benefits through the study on the healing environment, garden, therapeutic garden and viewing landscape and so forth. The research methods and measures used to assess health effects in the reviewed studies have applied in a different way ranged from quantitative methods (physical measures or quantitative observations) to qualitative methods (qualitative observations and surveys). In a literature review of research articles on the health outcomes have been found various research methods and measures used to assess health effects. This study will be concentrated mainly on methodological considerations in order to find the significant evidences related to evidence-based design (EBD). Future research should build the body of methodological knowledge to find more empirical evidences as sound scientific data and to improve the effectiveness of design interventions.
