Fuzzy set expressing category in fuzzy rating, which is a kind of psychological scaling, is dependent on situations. This paper assumes that a mapping exists between fuzzy sets expressing categories in some situation and those expressing same categories in another situation. fuzzy sets expressing categories in some situation are obtained by fuzzy sets expressing categories in another situation and the mapping between them. The usefulness of the present method is confirmed by the experiments comparing fuzzy sets obtained by the presented method with those identified directly by fuzzy rating. The normalized distance is used to compare both fuzzy sets and the experimental results show that the normalized distances between both fuzzy sets are enough small and that the presented method is useful for psychological scaling.

유비쿼터스 시대의 도래로 RFID/USN 기술이 다양한 분야에 널리 적용되고 있다. 교육분야에서도 RFID/USN 기술을 활용하여 교육환경의 개선에 관한 연구가 많이 나오고 있지만, 직접적인 학습에 응용하고 접목하는 연구는 미미한 편이다. 이에 본 논문은 RFID/USN 기술을 이용하여 학습자의 위치와 상황을 인지하고 그에 부합하는 중국어 상황학습 시스템을 제안한다. 영어에 비해 중국어가 가지고 있는 특징을 반영한 RFID 미들웨어는 PDA 기반에서 동작하는 모바일 RFID 미들웨어로 중국어 상황학습에 적합하도록 개발되었다. USN 환경에서는 센서 네트워크의 실시간 컴퓨팅 능력 및 무선 통신 능력을 통해 주변의 환경정보를 전송하여 학습자의 상황에 따른 상황학습에 도움을 주도록 설계하였다. 시스템에 관한 분석을 위해 소집단을 대상으로 하는 파일럿 테스트를 실시하였다.

This paper proposes a method to track object of real-time video transferred through single web-camera and to recognize risk-situation and human actions. The proposed method recognizes human basic actions that human can do in daily life and finds risk-situation such as faint and falling down to classify usual action and risk-situation. The proposed method models the background, obtains the difference image between input image and the modeled background image, extracts human object from input image, tracts object's motion and recognizes human actions. Tracking object uses the moment information of extracting object and the characteristic of object's recognition is moment's change and ratio of object's size between frames. Actions classified are four actions of walking, waling diagonally, sitting down, standing up among the most actions human do in daily life and suddenly falling down is classified into risk-situation. To test the proposed method, we applied it for eight participants from a video of a web-cam, classify human action and recognize risk-situation. The test result showed more than 97 percent recognition rate for each action and 100 percent recognition rate for risk-situation by the proposed method.

Through this study, some considerations to be taken into account in order to construct the user model for the user friendly system which can provide each individuals user armed with varied intellectual level with the relevant information, can be summarized as follows : (1) The user' ability to use the system and users' subject knowledge, the distribution of the users' level knowledge should be considered for the decision of the typed of interaction between the users and the system. (2) the knowledge of the user models should include the following kinds of knowledge inharmony with one another, 1. Standard user knowledge which represents a general characteristic of user group, 2. individual user knowledge which represents an individual's unique characteristic, 3. Long-term user knowledge which represents the education level and subject background of users, 4. short-term user knowledge which represents the purpose of information science and information need by users (3) As knowledge generation technique, both the implicit method and explicit method should be a n.0, pplied, observation of the system during the interaction, and explicit method generates the knowledge by the user's answering the questions already made by the system. (4) The frame technique as the knowledge representation for the user-modelling in which user-knowledge is represented in a limited situation and in a qualitative aspects, can be recommended. The frame is adequated for the explanation of structured situation, and for the processing the present situation by inferring the previous experiences.

The speech synthesis technology is widely used and its application area is also being broadened to an automatic response service, a learning system for handicapped person, etc. However, the sound quality of the speech synthesizer has not yet reached to the satisfactory level of users. To make a synthesized speech, the existing synthesizer generates rhythms only by the interval information such as space and comma or by several punctuation marks such as a question mark and an exclamation mark so that it is not easy to generate natural rhythms of people even though it is based on mass speech database. To make up for the problem, there is a way to select rhythms after processing language from a higher level information. This paper proposes a method for generating tags for controling rhythms by analyzing the meaning of sentence with speech situation information. We use the Systemic Functional Grammar (SFG) [4] which analyzes the meaning of sentence with speech situation information considering the sentence prior to the given one, the situation of a conversation, the relationship among people in the conversation, etc. In this study, we generate Semantic Speech Control Tag (SSCT) by the result of SFG's meaning analysis and the voice wave analysis.

The purpose of this study was to investigate the degree of self-monitoring (SM), the task situation and the appeal type of advertising impact on consumer behavior: in inner wear purchase. Information for the study was obtained with the use of experimental design. the experimental materials for the study were two-type inner wear advertisements (image appeal Ad/product appeal Ad). The subjects were 270, who were randomly sampled women undergraduate students in Korea, and main-test subjects (70 high SM subjects/69 low SM subjects) were assigned to the cells of 2 (self usage/gift-giving)x2 (quality appeal Ad/image appeal Ad). According to the 2x(2$\times$2) mixed factorial design, the level of SM score, the type of task situation score and the level of appeal type of advertising score were compared and tested by analysis of ANOVA. The results of experiment were as follows: 1. Experimental 1. the results showed the product preference on inner wear was the significant 3-way interaction effects among the degree of SM, the task situation, and the appeal type of advertising as well as the significant main effects of the appeal type of advertising. That is, the situation impact differs from the appeal type of advertising according to the degree of SM. 2. Experimental ll. the results showed the purchase intention on inner wear was the significant 2-way interaction effects between the appeal type of advertising and the task situation as well as the significant main effects of the appeal type of advertising and the task situation. That is, there is considerable difference in gift-giving situation rather than in self- usage situation according to the appeal type of advertising.

The concept of SDN (Software Defined Networking) endows the network with programmability and significantly improves the flexibility and extensibility of networks. Currently a plenty of research works on introducing SDN into wireless networks. Most of them focus on the innovation of the SDN based architectures but few consider how to realize the global perception of the network through the controller. In order to address this problem, a software defined carrier grade Wi-Fi framework called SWAN, is proposed firstly. Then based on the proposed SWAN architecture, a blueprint of introducing the traditional NSA (Network Situation Awareness) into SWAN is proposed and described in detail. Through perceiving various network data by a decentralized architecture and making comprehension and prediction on the perceived data, the proposed blueprint endows the controllers with the capability to aware of the current network situation and predict the near future situation. Meanwhile, the extensibility of the proposed blueprint makes it a universal solution for software defined wireless networks SDWNs rather than just for one case. Then we further research one typical use case of proposed NSA blueprint: network performance awareness (NPA). The subsequent comparison with other methods and result analysis not only well prove the effectiveness of proposed NPA but further provide a strong proof of the feasibility of proposed NSA blueprint.

본 논문은 재난 상황 발생 시 승객 및 대피자에게 안전하게 대피 경로를 제공하는 동향 분석에 관한 연구이다. 동향 분석을 위해 국내외 논문과 국내특허를 주로 살펴보았으며, 최근 15년 이내의 국내외 논문 31편, 국내 특허 29건, 논문을 통한 기 수행된 국가과제 9건을 분석하였다. 분석 결과 기존의 연구는 대피 유도 시스템 중심으로 수행되었으며, 대피자 관점에서 실제로 활용될 수 있는 수준의 실내 재난 대피 기술에 대한 연구는 전무한 것으로 나타났다. 이는 실내 공간에서 위치인식 기술의 부재 또는 한계점이 있는 것으로 파악되었고 이를 해소하기 위해 기술로 본 논문에서는 실내 위치인식기술의 활용을 제안하였다. 실내 재난 상황을 고려한 새로운 시스템 연구 및 개발의 기초 자료로 활용될 수 있을 것으로 기대된다.
