Purpose : The aim of this study was to investigate correlation between retention of fluid and PWV/ABI. Methods : The sample consists of 35 women who took plethynography(VS-1000;Fukuda Co.Ltd, Japan) at Oriental medicine exhibition held in COEX mall from August. 26. 2004 to August. 29. 2004. They were asked the intensity of the symptoms like dizziness or headache, nausea or bowel trouble, coldness in knee, and palpitation(1:none, 2:a little, 3:mild, 4:moderate, 5:severe). Women who answered 1,2 were classified as control group, and women who answered 3,4,5 were experimental group. Result : There was stastically significant correlation between dizziness and ABI Conclusion : It is believed that ABI may be the favorable alternative to the diagnosis of dizziness or headache.

Most public guide robots installed in public spots such as exhibition halls and lobbies of department store etc., have poor capability to distinguish the users who require services. As to provide suitable services, public guide robots should have a human detection system that makes it possible to evaluate intention of customers from their movement direction. In this paper, a DPS (Directional Perception System) is realized based on face detection technology. In particular, to catch human movement efficiently and reduce computational time, human detection technology using face rectangle, which is obtained from the human face, is developed. DPS determines which customer needs services of public guide robots by investigating the size and direction of face rectangle. If DPS is adapted, guide service will be provided with more satisfaction and reliability, and power efficiency also can be added up because public guide robots provide services only for the users who expresses their intentions of wanting services explicitly. Finally, through several experiments, the feasibility of the proposed DPS is verified.

In this study we develop core technology of Multi-Charmel Voice Guidance System based on active 2.45GHz RFID that can be used in the field of advertising. Through this, we can service more familiar with voice information to foreigners by own language in large scale international event. As an alternative to the current high-expensive voice guidance system in exhibition hall and provide more value added services to user. As the result, we present the configuration of integrated software platform which include media server, media client and receiver. It can be as a basis infra equipment for a signtseeing in RFID/USN environment. Additionally through tag information analysis about exposure of advertisement that is collected late, supposed system may achieve role as a new marketing tool.

Since the business scales of retailing companies become to be very large and the number of items dealt increases explosively, automation of inventory management becomes one of the most important issues to solve in retailing industry. In order to accomplish this automation of inventory management, there must be a great need to a method which can perform real-time decision making on inventory control in an automatic fashion, while communicating with inventory information systems like POS system and automatic warehousing system. But even in this circumstance, there are also many obstructions to such automation like varying demands, limited capacity of warehouse and exhibition room, need for strategic consideration on inventory control, etc., in a real sense. Due to these reasons, it seems very difficult that most large-scaled retailing companies get fully automated inventory management system. To overcome those difficulties and reflect them into inventory control, we propose a automated inventory control methodology for retailing industry based on neural network and policy model. Especially, policy model is devised to deal with dynamic varying demands and using this model, strategic goals on inventory can be considered into inventory control mechanism. Our proposed approach is implemented in workstation and its performance is also empirically verified also against to real case of one of the major retailing firm in Korea.

디지털 문화유산의 활용범위가 확대 되면서, 국내에서도 체계화된 디지털 문화유산 연구가 필요하게 되었다. 유럽에서 진행된 EPOCH 프로젝트는 디지털 문화유산 연구의 표준화 작업, 기술과 역사학 간의 학제간 연계 증진 방안 연구, 디지털 문화유산의 실질적인 활용방안 모색 등의 결과를 이루었다. 이를 경영 기술 문화 영역에서 분석함으로서 앞으로 진행될 디지털 문화유산 프로젝트의 방향을 발견할 수 있었다. 본 논문에서는 정책분야에서 디지털 문화유산의 독립적인 연구 분야 확립과 박물관의 민간 자본 투입을 제안하고, 연구 분야에서는 맞춤형 기술을, 그리고 경영학 측면에서의 연구 필요성 등을 제안한다.

In this paper, we consist of three dimensional acceleration sensor as a small-sized sensor module to acquire base technologies that need to estimate exhibition audience' moving distance. and that we developed algorism and device that can calculate acceleration in gravity direction with attaching it to people's body part without regard to three dimensional direction. By making use of the sensor module, we have to process the data that let it quantitatively process possible to measure people's walk and movement by computer system. We normalized sensor output data in the process of change from sensor module to acquisition of data, rectangular coordinates and single scalar acceleration value in gravity direction. Printed out sensor data attaching sensor module to people's body part is used for motion pattern detection after normalization, Motion sensor devised mode change algorism because it print data of other pattern according to attached position of body. For algorism design, we collected data occurring during walking about subject and we also defined occurring problem domain after analyzing the data. We settle defined problem domain and that we simulated the walking number measuring instrument with highly efficient in restricted environment.

IAU 창립 100주년을 맞이하는 시점에서 현대 천문학의 주요 주제들을 다룬 체험형 특별전 '우주연구실 인턴체험전'을 기획하여 과천과학관에서 45일간 운영하였다. 유·초등 어린이로부터 중·고등 청소년과 성인에 이르는 다양한 연령층의 약 5만 명이 전시를 관람하였다. 전시의 주요 연출방향은 현대적인 천문학 연구성과를 대중과 공유하되, 관람객 스스로가 연구과정에 대한 이해를 통해 결과를 인지할 수 있도록 하는 것이었다. 1900년대 이후 천문학자들의 실제 연구방법과 원리를 단순화한 체험요소들을 개발하여 인간의 우주에 대한 호기심과 탐구의 흐름에 따라 관람할 수 있도록 전개하였다. 또한 관람객이 인턴연구원 과정을 수료하는 형태로 관람동선을 연출하여 전시내용을 보다 적극적으로 탐구하게 하였다. 전시 관람객 인식조사 결과, 전시를 통해 '암흑물질'을 새롭게 알게 되었다고 한 응답자가 가장 많았고, 그 외 우주의 규모, 블랙홀과 외계행성 관측, 아직 밝혀지지 않은 것들이 많음을 알게 되었다는 응답이 주를 이뤘다. 전시물에 대한 평가로는 직관적으로 거리-광도 관계를 보여주는 전시물과 블랙홀에 대한 이해를 돕는 체험전시물들에 대한 만족도가 높았고, 전시해설이 전시내용을 이해하는데 도움을 줬다는 응답자가 많았다. 여전히 초등 저학년이 이해하기 쉬운 전시물이 필요하다는 과제가 남아있다.

In this study, we developed a fuel moisture variation prediction model on each day after precipitation during a spring forest fire exhibition period. For this research, we selected plots in pine forest on Sam-Chuck si and Dong-hae si in Kangwon do according to a forest density(low, mediate, high) and classified a surface woody fuel by a diameter.(below 0.6cm, $0.6{\sim}3cm$, $3{\sim}6cm$, and above 6cm). A validity of this model was verified by applying a fuel moisture variation after precipitation in this spring. In the result, $R^2$ was $0.76{\sim}0.92$. This model will be a useful for improvement of a forest fire danger rate forcast through a prediction a fule moisture in forest.

German architect Hans Scharoun (1893-1972) has long been known as an Expressionist Architect, but recent scholarships reveal that his architectural pieces represent a profound idea of modern functional building. In this context, his architectural tendency can be constructed as an advanced functionalism. In the early twentieth century Germany, many young architects were not given chances to build due to economic hardship after World War I, and they were naturally led to imagery sketch designs for future architecture. Scharoun began with utopian fantasies as one might easily notice through his watercolor paintings in the Glass Chain period, but further developed his vision into a more concrete idea on organic building which he believed to be a modem functionalism. This paper intends to exemplify Scharoun's modern functionalism through a detailed analysis of his design of Weissenhofhaus presented at Stuttgart Deutscher Werkbund Exhibition in 1927. Weissenhofhaus is often rebuked for its expressionist qualifies by famous critics such as Sigfried Giedion and Nikolaus Pevsner, but the house also suggests other possibilities within the Modern Movement in Architecture. In particular, Weissenhofhaus is chosen for its historical importance linking two world war eras in German modern architecture.

박물관에서의 디지털 전시의 확장에 따라 사용자의 경험 또한 점차로 강조되고 있는 추세이다. 그러나 기존의 박물관 관련 게임 연구는 주로 게임 개발 기술과 사례 소개 등 개발자 중심의 연구가 주를 이루어 왔으며 다양한 분야의 연구를 융합하여 기준을 제시하고자 하는 노력은 아직 미미한 실정이다. 이에 본 논문에서는 박물관 전시로서의 기능성 게임이 박물관의 목적에 부합하게 디자인되기 위한 가이드라인을 제시하고자 하였다. 이를 위해 박물관 교육, 공공장소에서의 HCI, 기능성 게임, 유니버설 디자인 등의 분야에서 박물관 게임과 관련된 문헌을 찾아 각 분야 연구를 내용분석하여 코딩한 후 좋은 디자인의 기준을 종합하여 정리하였다. 연구 결과 인지/물리, 개인/사회적 맥락 학습모형에 기초하여 총 16개 항목의 가이드라인이 추출되었다. 본 연구에서 개발된 가이드라인은 향후 박물관 내 기능성 게임의 디자인과 전시의 질을 향상시키는데 사용될 수 있을 것이다.
