Currently in Korea, Researches on universal design have been actively accomplished in various fields as not only housing and public space, but also product design and education. The purpose of this study is to analyze previous researches on universal design and to identify its research trends which might suggest the future directions of the related studies. In this study, researches on universal design were analyzed to classify the types according to research area, objects and respondents. Two hundreds twenty one papers(journal articles, theses, dissertations, etc.) which were published in Korea from 1997 to 2008 were analyzed. The results were as follows. Researches on universal design have increased quantitatively and research topics have been diverse. In the 1990s, with the introduction of universal design concept, research area focused on space design, but since 2000 researches on universal design have been expanded to apply the fashion, product design and education. In terms of research objects, the studies about evaluation and case analysis have conducted more than those about principles and planning design. With regard to research respondent, the studies for the elderly or people with disabilities and those of all people including a specific target have conducted in a similar ratio. Previous studies were contributed to expand the topics of universal design and it is time to study the applications based on previous research results for utilization and dissemination of universal design. Also it is necessary to conduct interdisciplinary studies in the field of universal design.

Solid freeform fabrication (SFF) technology plays a major role in industry and represents a reasonable percentage of industrial rapid prototyping/tooling/manufacturing (RP/RT/RM) development applications. However, SFF technology still has long way to progress to achieve satisfactory process speed, surface finish and overall quality improvement of its application. Today, three dimensional printing (3DP) technique that is one of SFF technology is receiving many interests, and is applied by various fields. It can fabricate three dimensional objects of solid freeform with high speed and low cost using ink jet printing technology. However, need long curing time after manufacture completion. And it must do post-processing process necessarily to heighten strength of objects because strength of fabricated objects is very weak. Therefore, in this study, we proposed an improved 3DP process that can solve problems of conventional 3DP process. The general 3DP process is method to spout binder simply through printer head on powder, but proposed process is method to cure jetted UV resin by UV lamp after jet UV resin using printhead on powder. The hardening of resin is achieved strongly at early time by UV lamp in proposed method. So, the proposed process can fabricate three dimensional objects with high speed without any post-processing.

One of the most important factors so that mobile objects can achieve their purpose is the information about their positions. In this paper, we propose an improved beacon system, to which ultrasonic sensors are attached, for the indoor localization of mobile objects. We have researched so that it can cover the wider space and estimate more accurate positions than the existent beacon systems. The existent beacon systems have the constraint that one beacon cannot cover wide area since ultrasonic sensors have limits in the angle of signal (beam-angle) on which their signal strength depends. Hence, we used the active beacon which consists of a pan-tilt mechanism and a beacon module. The active beacon system can always aim at mobile objects in order to transmit the strongest signal of the ultrasonic sensors into the objects using the pan-tilt mechanism. In addition, this system is inexpensive because it can decrease the number of beacons by about a half of the beacons of the existent system. Finally, the results show what is the difference between the active beacon system and existent beacon systems, and how accurate it is.

Surrealism's method of expression and inspiration has been a continuous influence on fashion. What is important is how to identify and research a source of inspiration, and how to use this inspiration to guide the designs that can be worn on a real human body. Therefore, the purpose of this study was to show how to develop ideas and designs from Surrealist objects and how to contribute to the development of designs to the diversity in visual and functional effects along with the changes in consumer's interest. Documentary studies about Surrealism and Surrealist-inflected fashion applying the works of Surrealist and fashion images as a tool of historical research were proceeded. And the ideas for theme, the motifs for print patterns, and the concept of designs were borrowed from Surrealist objects touching on the imagery between the real and reflected, optical and artificial, and the designs were developed with several different visual and functional effects changing color, pattern, size, and length with the function of zippers in each item. It also gives the person wearing it amusement because it includes the concept of play and D.I.Y. With effective planning, it is possible to attract consumer's interest in the market.

Unmanned aerial vehicles (UAV) and ground vehicles (UGV) require advanced video analytics for various tasks, such as moving object detection and segmentation; this has led to increasing demands for these methods. We propose a zero-shot video object segmentation method specifically designed for UAV and UGV applications that focuses on the discovery of moving objects in challenging scenarios. This method employs a background memory model that enables training from sparse annotations along the time axis, utilizing temporal modeling of the background to detect moving objects effectively. The proposed method addresses the limitations of the existing state-of-the-art methods for detecting salient objects within images, regardless of their movements. In particular, our method achieved mean J and F values of 82.7 and 81.2 on the DAVIS'16, respectively. We also conducted extensive ablation studies that highlighted the contributions of various input compositions and combinations of datasets used for training. In future developments, we will integrate the proposed method with additional systems, such as tracking and obstacle avoidance functionalities.

멀티미디어 표준안으로 제안된 MPEG-4는 객체기반 부호화 방식으로서, 객체를 효율적으로 분할하는 것은 MPEG-4에 있어 중요한 관건이다. 지금까지 이 분야에 대한 연구는 주로 rigid object를 대상으로 하였으나, 본 논문에서는 non-rigid object, 특히 구름이나 연기와 같은 non-rigid object를 대상으로 하여 효율적인 영역 분할 방식을 연구하였다. Non-rigid object는 모양이나 크기가 일정치 않으며 시간에 따라 형태도 변형되므로 정확히 분할해내는 것은 쉽지 않다. 따라서 본 논문에서는 이를 효율적으로 극복하기 위해 정지 영상에서는 watershed 알고리즘을 사용하여 non-rigid object를 분할해 주었다. 그리고 동영상에서는 intra-frame segmentation과 inter-frame segmentation을 통해 연속되는 프레임 내 관심 있는 객체의 경계선을 자동으로 추출해 주었다. 이 때 영상 내 경계 정보와 영역 정보 각각에 가중치를 두어 원하는 객체를 보다 정확히 추출해 주었다.

행정박물이란 공공업무의 활동을 반영하는 유형적 증거물로서 행정적 역사적 상징적 문화적 예술적 가치를 지니는 형상기록물이며 세계 여러 나라에서 제작되어 재질과 제작기법이 다양하지만, 재질조사 및 보존관리 시스템이 확립되지 않아 효율적인 보존관리의 어려움이 많다. 그러므로 본 연구에서는 금속류 행정박물에 대한 재질조사와 상태점검을 통하여 효율적인 보존관리를 위한 기초자료를 제시하고자 한다. 금속류 행정박물 중 상태점검 및 재질 분류는 공직자 선물 가운데 변색, 산화, 결손 및 균열이 기록된 12점을 선별하여 조사하였다. 행정박물의 전반적인 상태를 점검하기 위해 국내 박물관, 미술관 및 일본민족학박물관에서 사용하는 상태점검카드를 수집 정리하여 새로운 점검카드를 작성 후 금속류 행정박물을 점검하였다. X-ray를 통해 행정박물의 제작기법과 소재간의 결합방법, 구조상 취약부분에 대하여 조사하였으며 P-XRF를 사용하여 행정박물의 재질 분석을 시도하여 각 재질별 분류를 실시하였다. 점검결과 행정박물의 외형적 특성과 손상부분에 대한 점검이 가능하고 구조적으로 취약한 부분을 관찰 할 수 있었다. 또한 P-XRF 측정을 통하여 재질이 미상으로 기록된 행정박물의 재질을 밝혀내었고 기록카드에 기재된 재질과 다른 재질을 찾아낼 수 있었다. 행정박물의 상태점검 및 손상정도, 재질별 분류 방법은 향후 보존관리를 위한 자료로써 활용이 가능하며 재질에 따른 훼손 방지 및 관리를 위한 보존관리지침 수립 등 장기보존을 위한 기초자료로서도 활용이 가능한 것으로 보인다.

In this Paper is analyzed about FMS(Fieldbus Message Specification) service of FOUNDATION Fieldbus and designed using of UML(Unified Modeling Language). The FMS provides a number of services for reading, writing, and otherwise accessing objects. The FOUNDATION Fieldbus protocol is object oriented. The information in the devices is accessed in the form of objects. In FMS, the objects for configuring device and strategy in a node are listed in an object dictionary(OD). Each object is identified by an index. For example, every function block and every parameter has an index.
