Recently, the aspect of consumers' preference for design has been changed to a pattern of respect for personality, based on 'personal value of passion'. The differentiated personal passion of modern people does not allow them to select mass-produced industrial product, and leads them to choose life style different from others. Specially, consumers want to express. their differentiated personality by preferring and possessing the originally designed products. Therefore, the originally designed products that are clearly identifiable become the object of consumers' consideration, and stimulate the consumers' desire to purchase. According to new needs of consumers, it is required to reconsider the old design pattern of furniture based on simplicity and propose new design for furniture to meet the needs of consumers. Mass production has resulted in a strong focus on simplicity rather than difficulty and complexity of the production process. This tendency shows the design pattern that leans toward one side excluding the expression of correlative concept among design elements. This one sided design leads modern people to have no personality, and shows only simple and uniform expression of passion. Therefore, this paper is purposed to develop furniture with more personality by applying correlative concept that has been taken less seriously in the field of design to furniture design.

This study intends to acquire objective models for basic quantitative analysis of pattern and space through image-recognition technique, and verify the effectiveness of such acquired models. Many experiments showed that the recognized result can be varied depending on the different viewpoints and the analysis based on the single-viewpoint images does not provide objectivity. The experiment using multi-viewpoint image models, which was attempted as an alternative for the disadvantages, showed the recognition similar to that of the actual model. Especially, images generated at laboratory using miniature model may be useful in comparing and understanding plural number of patterns. The models that have been acquired using such images may be hard to use in acquiring images for analyzing actual building patterns or indoor space, although they may be useful in pattern analysis using miniature model. The disadvantage, however, can be supplemented with panorama VR and C. G. simulation technique. Steady researches are required on the application of visual information to the image recognition principle and the model for quantitative analysis of pattern and space in addition to the research on the construction of the model that can be used in comparing and analyzing not only form and space but also miniature models.

With the help of advanced image acquisition and processing technology, the vision-based measurement methods have been broadly applied to implement the structural monitoring and condition identification of civil engineering structures. Many noncontact approaches enabled by different digital image processing algorithms are developed to overcome the problems in conventional structural dynamic displacement measurement. This paper presents three kinds of image processing algorithms for structural dynamic displacement measurement, i.e., the grayscale pattern matching (GPM) algorithm, the color pattern matching (CPM) algorithm, and the mean shift tracking (MST) algorithm. A vision-based system programmed with the three image processing algorithms is developed for multi-point structural dynamic displacement measurement. The dynamic displacement time histories of multiple vision points are simultaneously measured by the vision-based system and the magnetostrictive displacement sensor (MDS) during the laboratory shaking table tests of a three-story steel frame model. The comparative analysis results indicate that the developed vision-based system exhibits excellent performance in structural dynamic displacement measurement by use of the three different image processing algorithms. The field application experiments are also carried out on an arch bridge for the measurement of displacement influence lines during the loading tests to validate the effectiveness of the vision-based system.

비파괴검사는 탐지물체에 물리적 손상을 가하지 않고 내부 정보를 파악할 수 있어 다양한 분야에서 이용되고 있다. 그 중 전자기를 이용한 물체의 형상추정방법의 경우 역 유한요소법을 이용하여야 하지만 이는 비선형성이 강하고 수치계산이 복잡하고 측정 센서의 개수가 미지수의 개수보다 훨씬 적어 정확한 결과를 얻는데 어려움이 있다. 본 논문에서는 탐지물체에 의한 자기장 변화 신호만을 이용하여, 물체의 시스템 내 각 센서별 위치에서 물체와 등가면적의 원의 비교를 통해 비교적 간편하게 자성물체의 부피를 판정하고 형상추정을 위한 다양한 보정과정을 거쳐 탐지물체의 형상판정이 가능한 알고리즘을 제안하고 검증하였다.

ESP(Electronic Speckle Pattern Interferometry) is an optical technique to measure deforamtion of engineering components and materials in industrial areas. ESPI, a non-contact and non-destructive measuring method, is capable of providing full-field results with high spatial resolution and high speed. One of important application aspects using electronic speckle pattern interferometry is to generate contours of a diffuse object in order to provide data for 3-D shape analysis and topography measurement. The electronic speckle contouring is suitable for providing measurement range from millimeters to several centimeters. In this study, we introduce the contouring method by modified dual-beam speckle pattern interferometer and a shift of the two illumination beams through optical fiber in order to obtain the contour fringe patterns. Before the experiments, we performed the geometric analysis for dual-beam-shifted ESPI contouring. And by this geometric analysis, we performed the electronic speckle contouring experiment. We used 4-frame phase shifting method with PZT for quantitative analysis of contour fringes. Finally, we showed good agreements between the geometric analysis and experimental results.

기존 소프트웨어 개발 프로세스는 분석 단계보다는 설계나 구현 단계만을 강조하고 있으며 서브시스템이 많은 복잡한 비즈니스 애플리케이션 분석 시 분석가의 경험이나 업무 지식의 차이에 따라 스타일과 추상화 레벨이 다른 분석 산출물을 작성하게 된다. 이러한 분석 산출물은 산출물 일관성이나 가독성에 영향을 미친다. 본 논문에서는 많은 서브시스템들에 대한 분석을 서로 다른 분석가에 의해서 수행해야 하고 외부 이벤트에 대해 트랜잭션 처리를 룰 기반으로 처리해야 하는 도메인 상에서 객체 기반의 중요 개념을 룰 기반으로 추출하고 그들 간의 상호작용 모델링을 효과적으로 할 수 있는 룰 기반 분석 패턴을 제시한다. 또한 제시한 분석 패턴이 가지는 3개의 핵심 개념들을 기반으로 UML Components 개발 프로세스 상에서 비즈니스 컴포넌트를 개발하는 방법을 은행 수신업무 적용 사례를 통해 제시한다.

The objectives of this study were to measure the preference and purchase intention on Korean traditional motifs and to investigate the relationship among preference, purchase intention, and sensibility. The subjects consisted of 217 male and 351 female US undergraduate students. The experimental materials used in this study were 48 stimuli and a questionnaire, composed of 7-point semantic differential scales of 17 bi-polar adjectives. The data were analyzed by ANOVA, Duncan's multiple range test, Regression, and t-test. The major findings were as follows; First, interpretation type and application object had significant effects on the preference, while category and interpretation type had significant effects on the purchase intension. The application of Korean traditional motifs for pattern design was preferred to their application for clothing design. Decorative type was found to be more related to the preference and purchase intention than the other interpretation types of realistic, stylized and abstract types. The purchase intention on crain motif was lower than the other categories of lotus and cloud motifs. Second, in overall, the preference on Korean traditional motifs was higher than purchase intention. Third, the preference and purchase intention were affected mainly by 'Quality' image, a component of sensibility, followed by 'Cheerfulness' image, but not affected by 'Simplicity' and 'Modernity' image.

This study focuses on comparative study of the representation of 'traditionality' in Asian hotel guest rooms. Hotel can be a concentration of the country's culture and tradition and provide unique experience to guests through its space, decoration, and material. However, most hotels in Korea are lack of a strong identity based on the Korean culture and tradition, due to adoptation of the western hotel styles without any criticism. The purpose of this study was to investigate the expression methods of the traditionality in Asian hotel guest rooms to provide design guideline to enhance identity of hotel guest rooms in Korea. Through analysis of the previous researches, criteria of the three design application methods and the five design elements were defined to analyze the representation of the traditonality. Design application methods were categorized as "Original form", "Partial adoption", and "Metaphor". Five design elements include "Shape", "Material", "Color", "Object", and "Pattern". Thirty nine Asian hotels containing the traditional design elements were explored in the study. In result, design application methods in Korea used all three methods equally, while other Asian countries used mainly the Partial adoption and Metaphor methods to express their traditions rather than the Original form method. All five deign elements were mostly used in case of the Original form methods, and two or three elements among five elements were used for the Partial adoption and Metaphor methods. The traditional representation of hotel guest rooms in Korea, reflecting current thinking, living pattern and culture, will be a solution for the new hotel design as well as elevation of Korea's status to a higher level.
