  • Design changes for an original surface model are frequently required in a manufacturing area: for example, when the physical parts are modified or when the parts are partially manufactured from analogous shapes. In this case, an efficient 3D model updating method by locally adding scan data for the modified area is highly desirable. For this purpose, this paper presents a new procedure to update an initial model that is composed of combinatorial triangular facets based on a set of locally added point data. The initial surface model is first created from the initial point set by Tight Cocone, which is a water-tight surface reconstructor; and then the point cloud data for the updates is locally added onto the initial model maintaining the same coordinate system. In order to update the initial model, the special region on the initial surface that needs to be updated is recognized through the detection of the overlapping area between the initial model and the boundary of the newly added point cloud. After that, the initial surface model is eventually updated to the final output by replacing the recognized region with the newly added point cloud. The proposed method has been implemented and tested with several examples. This algorithm will be practically useful to modify the surface model with physical part changes and free-form surface design.

  • RFID 태그 생산 분야에서 RFID 칩 본딩 과정 이후에 RFID 태그 불량 검출 기능을 수행하는 불량 검출 시스템 개발이 요구되어 왔다. 그러나 RFID 태그의 특징을 이해하면서 제대로 된 설계 개념을 가지고 구현된 시스템을 설계하기가 어렵고 사소한 기능의 변화에도 시스템을 처음부터 설계를 해야 하는 어려움이 있었다. 이 논문에서는 RFID 태그 불량 검출 기능을 수행하는 불량검출 시스템을 UML을 이용하여 객체지향 기법으로 설계하고 UML로 설계된 모델링을 객체지향을 지원하는 비주얼 언어인 LabVIEW OOP로 적용하는 방법을 제시한다. UML과 LabVIEW OOP로 설계되고 구현된 불량검출 시스템에 대한 성능과 시스템의 기능 변화에 따른 재설계 기법에 대한 기법도 제안한다.

  • This study aimed at revaluating Frank Gehry's freeform constructions. To this end, the study analyzed the way the space composition and circulation system of general constructions are connected with newly extended parts in the Art Gallery of Ontario and, based on this, comparatively analyzed freeform constructions before and after the art gallery, finding out what changes were made in the exterior and interior spaces of freeform constructions built after the art gallery. The results of the study are as follows. First, starting from extending the Art Gallery of Ontario, Gehry came to use glass instead of metal as main material of freeform constructions. In order to create the circulation connecting the existing building and the extended mass, Gehry applied continuing circulation for the first time to the gallery. Third, in addition to design motives, such as the woodblock print depicting a carp by Hiroshige, still life depicting a glass bottle by Morandi and the crease of the shawl in Vermeer's paintings, which Gehry applied to freeform constructions, the design motif which was recently acquired from Pyrenees rock was added. Fourth, the trend of mall construction appeared before and after the Art Gallery of Ontario. Finally, Gary used the shape of fish as a design motif for his work at an important turning point in his Freeform Architecture.

  • Objective: The purpose of this study was to identify whether cutaneous sensory (CS) changes induced by mechanical intervention (MI) increases the trigger point threshold of the same spinal segment as well as to investigate the relationship between the amounts of change in CS pressure pain thresholds (PPT). Design: Randomized controlled trial. Methods: Thirty-nine persons with myofacial pain (MFP) were recruited in this experiment. The subjects consisted of 20 men and 19 women (age 20-39). MI was applied on the subjects using the Graston technique for 5 minutes to induce CS changes. The CS changes were measured with sensory tests by using the Von Frey Filament, and PPT changes were estimated by using the pressure threshold meter. For the observation of sensory and PPT changes with time, the test was conducted for 15 minutes including a pre, post, and after intervention session. Results: CS threshold increased significantly when MI was applied (p<0.001). On the same spinal segment, changes in the right infraspinatus PPT was observed (p<0.001) but the PPT changes in other muscles were not significantly different. Furthermore, the control group CS and PPT were not significantly different. In addition, regression analysis showed that the CS changes have a larger impact on PPT in the same spinal segment (p<0.001). Conclusions: CS changes induced by MI make to change PPT on the same spinal segment. In other words, it is possible to identify PPT changes following CS changes except for the muscle which belongs to a different spinal segment. Therefore, application of MI is necessary for the CS changes in the same spinal segment. Furthermore, it can be useful in the clinical fields as a method of providing pain control and increasing the PPT.

  • A matter of primary concern about all the design is concentrated on how to create more valuable things to allow people to live an affluent life. However, it is very difficult to achieve the goal because every design work is changed in accordance with given situations. Situations are changeable, so is design. There is no progress without change, but change is not necessarily progress. It is highly desirable that their changes be beneficial to mankind. Our main problem is to be able to discrimination between which should be discarded and that which should be kept, built and improved Viewed at this aspect, it is significant to study the relation between globalism and cultural identity of design, because every design has been constantly influenced by global trends and local characteristics. The paper is composed of four parts Introduction, Characteristic of global design, Cultural identity of design and Conclusion In Introduction, the purpose and background of the study are presented. In Chapter1. social back ground, multi-kinds smallproduction and new problems and searched. In Chapter2, vernacular design, transmission and propagation and tradition and innovation are considered. In Conclusion, some suggestive words on the subject are mentioned.

  • Digital technology makes changes of people's behavior style and characteristic of space in which people live. Therefore, we need to adjust conceptual meaning related to digital technology properly. For deriving emotional interactive space design, we need to understand following meanings: the meaning of interaction and interaction design, the meaning of emotion and emotional design, the meaning of space, emotional design, and interaction design in digital society. Consequently emotional interactive space design makes people satisfied with their five senses, communication with people increase and enable people to experience something new that they haven't experienced before transcending time and space.

  • Recently, the MZ generation has been leading overall fashion trends, and fashion companies focus on design, marketing, and new products targeting the MZ generation. However, it is expected that a fit problem may occur if the M and Z generations are combined when producing clothing. Therefore, this study aims to analyze the differences between the two groups by comparing the body size according to the classification of the M and Z generations. In addition, this study analyzes whether the body shape of the MZ generation is different from the past generations and analyzes major changes in body size for clothing manufacturing through graphical visualization. As for the research method, a t-test was conducted to verify the significant difference between the measurements for each age group. Generation M was defined as those who are 27-39 years old, and Generation Z was defined as those who are 20-26 years old. In order to examine the changes in body measurements according to the measurement year, the 7th Size Korea and 8th Size Korea data were analyzed. In order to examine the visual changes according to the measurement year and age group, major measurements of clothing construction were analyzed. As a result, it was found that Generation M had a significantly higher height item than Generation Z. Also, in terms of circumference, width, and thickness, Generation M was larger than Generation Z. But the size of the bra cup was larger in Generation Z than Generation M. As a result of analyzing the body size changes, in the height item, the 8th Size Korea measurements were found to be significantly higher in shoulder height and navel level waist height. In the length and circumference items, the 8th Size Korea measurements were larger than the 7th. In the width, thickness, and other items, the 8th measurements were larger than the 7th.

  • 본 논문은 Korsch 망원경의 열분석을 통한 광학계 성능 평가 방법 및 비열화 구조를 연구하였다. 비대칭성의 복잡한 구조를 가진 광학계의 경우, 광학 설계 소프트웨어에 열팽창 계수를 적용하여 인공위성 구조를 구현하는데 한계가 있어 온도 변화에 대한 광학계 성능 평가가 이루어지기 어렵다. 이러한 문제점을 해결하기 위해 기계 설계 소프트웨어를 이용하여 온도에 따라 광학계에 영향을 주는 모든 구조체에 길이 변화를 구현하였고, 온도 변화에 대한 광학 부품 사이의 거리 변화량을 정리하였다. 또한 광학 설계 소프트웨어를 이용하여 온도 변화에 대한 광학 부품의 형상 및 두께 변화량을 정리하였다. 두 소프트웨어에서 도출한 모든 변화량을 광학 소프트웨어에 적용하여 광학계의 성능 평가를 진행하였다. 그 결과 공간 분해능 71.4 cycles/mm에 대한 변조전달함수(MTF)가 9 ℃에서 33 ℃까지의 범위에서 25% 이상 유지되는 것을 확인하였다. 또한 광학계 성능 변화에 가장 영향을 많이 주는 구조체를 찾아, 영향을 줄이도록 비열화 구조를 도출하여 개선된 구조물을 적용한 광학계의 성능 평가를 진행하였다. 그 결과, 분해능 71.4 cycles/mm에 대한 변조전달함수가 9 ℃에서 33 ℃까지의 범위에서 67% 이상 유지되는 것을 확인하였다.

  • 본 연구는 캡스톤 디자인 기반의 장애아와 비장애가 함께 놀이하는 장애교재교구 제작 수업을 통하여 예비보육교사들에게 장애 인식, 통합교육 태도 및 교사효능감의 변화와 차이를 파악하는 것을 목적으로 하였다. 연구 참여자는 수도권 3년제 K대학에서 2020년 한 학기 동안 캡스톤 디자인 수업에 참여한 보육 전공학생 3학년 50명(실험집단 25명, 비교집단 25명)이며, 양적 및 질적 연구를 혼합하여 적용하였다. 연구결과를 살펴보면 장애교재교구를 제작한 실험집단이 비교집단 보다 장애 인식과 통합교육에 대한 태도 및 교사효능감에서 유의미한 변화를 보였다. 장애인에 대한 전반적인 이해와 지식이 증가하여 장애 인식에 긍정적인 변화가 있었다. 이러한 장애 인식의 긍정적 변화는 통합교육에 대한 태도와 교사효능감에도 긍정적인 변화를 준 것으로 판단된다. 예비보육교사의 이러한 긍정적인 변화는 통합교육현장에서 장애유아와의 상호작용 시, 교사의 다양한 역할과 교수행동의 질을 높이는 계기가 될 것이다.
