This paper proposes a 3D fashion design system that generates a 3D clothes model by using 2D patterns of clothes and drapes the 3D clothes model on a 3D human model. In the proposed system, 2D patterns of clothes are designed by selecting comer points of 2D mesh. After designing 2D patterns, a 3D clothes model is designed by describing the control points to be connected between 2D patterns. The proposed system reads a 3D human body model file and the designed 3D clothes model and creates a 3D human model putting on the clothes by using the mass-spring model based physical simulation. It calculates collision and reaction between the triangles of human body model and those of clothes for realistic simulation. Because the number of triangles is very large, the collision and reaction processing need a lot of time. To solve this problem, the proposed system decreases the number of collision and reaction processing by using the Octree space subdivision technique. It took a few seconds for generating a 3D human model putting on the designed 3D clothes.

Mass customization is a paradoxical word which has some difficulties in introducing to consumer electronic industry due to its mass production system for economy of scale. On the basis of literature review and case studies, this study suggests the mass customization model and design strategy suitable for consumer electronic industry in the aspect of product design. Mass customization models are divided into manufacturer side customization, deliverer side customization, and customer side customization. And the fast is considered as appropriative to consumer electronic industry. Collecting customer 's needs, modular product design, and adopting basic product platform for derivation by 3rd party manufacturer can be used as design strategy for this model. For realization of the mass customization, further research in the area of the participative design for collecting practical design needs of customer wh o are inexpert to product design is needed.

This article summarizes the importance, definition, key strategies and future directions of sustainable packaging design.In modern society, sustainable packaging design is not only concerned with environmental protection and resource conservation, but also involves economic, social and cultural sustainable development.This paper explores strategies to reduce environmental burden and promote ecological balance by using environmentally friendly materials, optimizing packaging design, improving packaging recyclability and reuse. In addition, the article emphasizes the importance of design innovation, such as adopting a simplified design concept and modular system, as well as increasing the versatility of packaging.It also explores the application of life cycle assessment in packaging design to ensure that every step from design to disposal minimizes environmental impact. Finally, despite the environmental and social benefits that sustainable packaging design brings, it still faces technical, economic and regulatory challenges in practice.Future design will require interdisciplinary collaboration, integration of advanced technologies, consumer education and engagement, and enhanced policy and standard-setting to promote widespread adoption and practice of sustainable packaging.

홍수피해저감 대책의 우선순위 결정은 시스템 차원에서 접근해야 한다. 홍수피해저감 사업을 분야별로 분리하여 분석하면 숲을 보지 못하고 산을 판단하는 오류를 범할 수 있다. 홍수피해 최소화를 위한 여러 전문 분야별 대안 분석도 중요하지만, 시스템 차원에서 홍수피해 저감 방안을 파악하고 대책을 수립해야 한다. 따라서 본 시스템의 개발 목적은 최적의 홍수피해저감 대책을 결정하는 데 있어 각각의 개별 정보를 공유하고, 의사결정 지원에 필요한 시스템을 구축하는 데 있다. 본 연구에서 제시한 홍수방어 대책 통합평가시스템은 수문학적 홍수분석 모형을 비롯하여 수리학적 홍수분석 모형, 의사결정지원 시스템이 통합되어 단일 시스템으로 구축되며 이를 위해서는 구체적인 사용자 요구파악과 관련 업무 프로세스 분석을 통한 전체적인 시스템 구조 설계가 중요하다. 홍수방어 대책 통합평가시스템의 핵심 요소는 1) GIS입력 모듈, 2) Fuzzy 알고리즘 모듈, 3) MCDA 알고리즘 모듈, 4) 결과표출 모듈 등 네 가지이다. 여기서 첫 번째 모듈은 GIS 입력 모듈로써 최적 방안 도출을 위한 빈도별 홍수터, 홍수심, 토지이용도 등과 같은 일련의 GIS 기초자료를 제공한다. 두 번째 단계는 퍼지화된 MCDA 모듈을 수행하기 위한 퍼지 알고리즘 및 퍼지 연산을 위한 내부 코딩이 이루어지는 단계로써 사용자 요구 사항에 따른 연산이 가능하다. 세 번째 단계는 최적 방안을 모색하는 MCDA 알고리즘과 연산 수행을 위한 세부 모듈로 구성됐다. 마지막 네 번째 단계는 모형과 DB간의 연계절차로써 사용자가 직접 운영하는 GUI 부분으로써 사용자의 요구 사항을 비롯하여 모형의 특징을 Matlab 프로그램으로 각각의 화면을 디자인한다. 이 단계에서는 모형을 수행하기 위한 DB가 구축되며 사용자의 요구에 의한 맞춤형 분석이 가능하도록 구성됐다. 통합시스템을 통한 의사결정과정의 합리성은 선택된 최적의 홍수저감대책의 사회 경제적 수용성은 물론 의사결정과정의 투명성을 높일 수 있을 것이다.

Probe design is one of the essential tasks in successful DNA microarray experiments. The requirements for probes vary as the purpose or type of microarray experiments. In general, most previous works use the simple filtering approach with the fixed threshold value for each requirement. Here, we formulate the probe design as a multiobjective optimization problem with the two objectives and solve it using ${\epsilon}$-multiobjective evolutionary algorithm. The suggested approach was applied in designing probes for 19 types of Human Papillomavirus and 52 genes in Arabidopsis Calmodulin multigene family and successfully produced more target specific probes compared to well known probe design tools such as OligoArray and OligoWiz.

In this paper, we develope a detachable wearable device consisting of two parts: main module and accessary module including battery. The main module can display any tracking information and alarms related to the smart phone. In addition, it has small sensors such as heart rate sensor, NFC, T-money, and GPS that can be selected by user's requirement. The accessary module includes battery. The suggested wearable device can also solve the problems faced with today's many other wearable devices: 1) limited battery life 2) the lack of compatibility and expandability due to run on internal components designed for smart phone 3) the design has always been a crucial factor in determining the success of main stream consumer wearable devices.

In this paper, we propose a web page retrieval system based on the sensibility evaluation induced by the color combination of web pages. The realized system consist of two modules - the indexing module that automatically extracts and indexes the color information from the web page and the retrieval module that retrieves web pages based on the color combination when sensibility adjective is presented. Also, to verify the system usefulness, we analyzed the ranking of web pages retrieved by the system and by human subjects (non-expels and experts for color web page design) using two statistical methods of correlation and paired-t test. Results by non-experts showed the realized system was suitable for 10 sensibility adjectives among 18 sensibility adjectives, and results by experts showed that the realized system was suitable for 14 sensibility adjectives among 18 sensibility adjectives.

Recently, many performing arts facilities are under construction to accommodate people's various interest in cultural experiences. However, due to Korea's lack of know-how in such constructions and an absence of proper regulations on design planning, each designer designs and constructs the facilities differently, so several problems are occurring in the process of construction, such as high production cost for stage sets, high labor cost, low efficiency of stage work, and complicated work process. This resulted in low quality production of performance. This study is conducted to address the need for a systematic study on stage floor, and to propose an efficient way of regulating stage work in existing performing arts facilitiesand new facilities to be built. By a comparative analysis of performing arts facilities in Korea, and by analyzing stage floors of the facilities, this research suggests minimum modules as well as an appropriate unit of modules based on the minimum modules; and provides basic data on stage floors, which can be used for remodeling existing facilities orfor planning new cultural facilities. Also, this study suggests various ways of utilizing performing arts facilities in Korea.

This paper analyzes performances of modules in implementing a programmable multi-format video decoder. The goal of the proposed platform is the high-end Full High Definition (FHD) video decoder. The proposed multi-format video decoder consists of a reconfigurable processor, dedicated bit-stream co-processor, memory controller, cache for motion compensation, and flexible hardware accelerators. The experiments suggest performance baseline of modules for the proposed architecture operating at 300 MHz clock with capability of decoding HEVC bit-streams of FHD 30 frames per second.
