In this paper, we propose a motion estimation algorithm using hierarchical structure. The algorithm uses the image pyramids from the repetitive application of Gaussian filtering and decimation, and performs an inter-level displacement propagation in its motion estimation process. The motion estimation algorithm based on the hierarchical structure is shown to be very effective since this scheme utilizes the local imformation as well as the global imformation. The experimental results on the various data imdicate that compared to the Horn and Schunck's method, the proposed algorithm yields an accurate motion estimation with a fast convergence behaviour.

A systematic synthesis process is presented for the simulation of current-controlled grounded inductors. The process is used to obtain three circuits which are believed to be novel. One of the circuits has been implemented using linear operational transconductance amplifiers (OTA's). Computer simulation rusults are used to verify theoretical predictions. The results show close agreement between predicted behaviour and experimental performance.

In stereo vision applications, disparity estimation is often performed to corresponding pixels. Using window-based correlations is a fast and standard approach to the disparity estimation. In this paper, we analyse the behaviour of the correlation-based disparity estimation and improve its performance by combining it with a segmentation scheme. Simulation results demonstrate that the proposed algorithm provides faithful disparity maps.

The Operational Deflection Shape designates the motion pattern by which a structure vibrates under a specific operating condition. Modal Analysis is usually tested under test bench, but Operational Deflection Shape can be measured directly under real operating condition. It provide useful information for trouble-shooting and aid understanding and evaluation of the absolute dynamic behaviour of a machine or component. In this paper, It is analysed Excavator Upper Frame using Operating Deflection Shape.

The temporal structure of events on the discourse level has long been of great interest in both theoretical and computational linguistics. In this paper, we offer a unified approach to the temporal relationships related to a hierarchical discourse structure. We apply the method of pronoun resolution to the interpretation of tense. It is based on an analysis within the framework of the controlled information packaging theory. A unique aspect of our account is that temporal interpretation across discourse segments in global discourse is subject to the same principles as the interpretation of global anaphora, and that there is thus no need to postulate independent principles to account for the discourse behaviour of tense. In this way, we can neatly explain the general view that tense parallels the anaphoric nature of pronouns.

The purpose of this paper is to investigate the information needs and information seeking behavior of foreign students. A survey method was used for the undertaken study. The data were collected using a structured questionnaire, self-administered to 120 foreign students (60 males & 60 females) with 88 (47 males & 41 females) returns. The research is limited to post-graduate, M.Phil. and Ph.D. foreign students in University of Delhi. It was found that post-graduate students need information regarding their program of study while research scholars need information for writing research articles and for doing their research work. Most of them seek information through the internet. Research scholars used electronic resources such as databases, e-journals and e-theses and dissertations. 88.6% of the respondents also use books for seeking information. Their use of the library is limited with complaints about library staff and too few computer terminals. The present study will be helpful in designing new systems and services for the foreign students so that their information needs can be fulfilled easily. Further, findings of the study indicate that how the library professionals should assist foreign students to accomplish their information needs.

This study investigated how self-rated health and socioeconomic status are associated with behaviour of cancer survivors regarding desire for information. For this association, we compared survivors who did not seek information about cancer with those who did. We examined how sociodemographic, socioeconomic, cancerrelated, and health information factors are associated with self-rated health (SRH) by health information seeking/avoiding behavior in a survey of 502 post-treatment cancer patients. In the information seeking group, all four factors exhibited significant relationships with SRH. SRH values were significantly high for women (p<0.05), non-Hispanic White (p<0.05), and educated (p<0.01) participants, and for those who had high self-efficacy to use health information by themselves (p<0.01). Furthermore, in the information avoiding group, not only were there no significant relationships between socioeconomic status (SES) and SRH, but there were negative associations between their attitude/capacity and the SRH. In terms of communication equity, the promotion of information seeking behavior can be an effective way to reduce health disparities that are caused by social inequalities. Information avoiding behavior, however, does not exhibit a negative contribution toward the relationship between SRH and SES. Information seeking behavior was positively associated with SRH, but avoiding behavior was not negatively associated. We thus need to eliminate communication inequalities using health intervention to support information seeking behavior, while simultaneously providing support for avoiders.

이 연구의 목적은 정보행태에 있어 국민성이 갖는 의미에 주목하면서, 정보행태에 대한 집단적 요인과 개인적 요인의 비중을 상대적으로 가늠해 보는데 있다. 이를 위해, 국민성을 대변하는 요소로 국적과 성격(의존성)을 선정하였으며, 정보행태를 대변하는 10개의 지표를 개발하였다. 논의에 필요한 데이터는 설문조사를 통해 수집하였는데, 158명의 한국인 대학생과 183명의 일본인 대학생이 설문에 참여하였다. 수집한 데이터에 근거하여 변인들 사이의 관계를 검증하기 위한 빈도분석과 교차분석을 실시하였으며, 국적과 의존성의 상대적 비중을 가늠하기 위한 ANOVA 검증을 실시하였다. 통계적 분석의 결과, 상대적 비중에 있어 국적의 영향력이 의존성의 영향력보다 크며, 집단적 요인의 비중이 개인적 요인의 비중보다 큰 것으로 나타났다.

본 연구의 목적은 Web OPAC시스템 이용자들의 성격유형과 그들의 탐색행위 및 인터페이스 선호도 간에는 어떤 상관관계가 있는지를 분석하는 것이다. 데이터 수집은 이용자들의 성격유형을 파악하기 위해서는 MBTI를 사용하였고, 이들의 Web OPAC시스템 탐색행위와 인터페이스 선호도를 측정하기 위해서는 총28개 요소들로 이루어진 자체개발한 온라인 설문지를 사용하였다. 이 실험에는 K대학교 재학생 48명이 자발적으로 참여하였고, 이들의 성격유형은 MBTI 4가지 선호지표인 외향성-내향성, 감각형-직관형, 사고형-감정형, 그리고 판단형-인식형으로 코딩 하였다. 수집된 데이터는 SPSS Windows Ver. 11.0을 사용하여 분석하였고, 상관 관계 분석을 위하여 Pearson의 상관계수(r)를 사용하였다. 데이터분석 결과 이용자들의 MBTI 선호지표와 9개 Web OPAC 탐색행위 및 인터페이스 선호도 요소들 간에 통계적으로 유의한 수준의 상관관계를 보였다.

복잡계 관점에서 트래픽 패턴, 도시 및 다세포 생물학적 유기체 등이 하나의 창발적인 현상인 것처럼, '그린 IT'의 개념 또한 지구 온난화 문제로 인해 인간 세계에서 태동할 수밖에 없는 불가피한 창발적인 현상이다. 복잡계 이론의 관점에서 그린 IT는 무작위한 것으로부터 대단히 복잡한 방식으로 상호작용을 하는 상당히 뒤얽힌 시스템으로 발전할 가능성이 높다. 그렇지만, 그린 IT 시스템 또한 하나의 복잡계라 할 때, 그러한 시스템을 구동시키고 억제시키는 미지의 끌개들이 존재한다. 이러한 맥락에서 본 논문은 그린 IT 시스템의 잠정적인 끌개들을 식별하고, 평가할 수 있는 하나의 새로운 모델을 제안하고, 이를 교육적으로 활용하는데 있다. 구체적으로 그린 IT의 끌개라 할 수 있는 그린 IT 너비-깊이 행렬을 기반으로 그린 IT 진화 및 자기조직화 되어가는 과정을 측정할 수 있는 유형-2 퍼지 시스템을 구축한다.
