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.

As digital cultural heritages have been applied to various fields, more systematic research on the domestic digital cultural heritage need to be improved. The EPOCH project by European Union contributed to standardization of ICT+CH domain, creation of network between different organization, and study of socio-economic impact of digital cultural heritage. We can find a way to improve domestic digital cultural heritage projects by analyzing EPOCH project in each management technique culture view. Based on these analysis this paper suggests the necessity to establish an independent research domain for digital cultural heritage, investment in heritage sites by private companies, and research to fit better with the user's need, and study on business administration in digital cultural heritages.

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.

Digital interactives in museums are expanding and user experience is becoming the focus of exhibition design. The purpose of this study was to suggest guidelines for serious games as a part of museum exhibits. To achieve this, studies on museum education, public space HCI, serious games, and universal design were analyzed by using content analysis methods. Results included 16 quality standards from cognitive, physical, and personal/social models. The findings from this study could benefit the design of future museum gaming interactives.

Serum lactate dehydrogenase isoenzymes are separated 5 fractions($LD_1-LD_5$) in normal serum by agrose electrophoresis. An unusual band on the cathodic side of $LD_5$ isoenzyme has been found on lactate dehydrogenase electrophores is of serum, called $LD_6$, and the presence of which signifies a poor prognosis for the patients of myocardial infarction. In recent, we have experienced $LD_6$ in two patients with myocardial infarction. Cardiac arrest was noted within 24 hours after exhibition of $LD_6$ extraband and they did not recover from their illness.

Biometric technology with the advance of deep learning enabled the new types of content. Especially, face recognition can provide immersion in terms of convenience and non-compulsiveness, but most commercial content has limitations that are limited to application areas. In this paper, we attempted to overcome these limitations, implement content that can utilize face recognition technology based on realtime video feed. We used Unity engine for high quality graphics, but performance degradation and frame drop occurred. To solve them, we augmented Dlib toolkit and adjusted the resolution image.
