Automatic speech recognition (ASR) has been successfully applied to many real human computer interaction (HCI) applications; however, its performance tends to be significantly decreased under noisy environments. The invention of audio visual speech recognition (AVSR) using an acoustic signal and lip motion has recently attracted more attention due to its noise-robustness characteristic. In this paper, we describe our novel integration scheme for AVSR based on a late integration approach. Firstly, we introduce the robust reliability measurement for audio and visual modalities using model based information and signal based information. The model based sources measure the confusability of vocabulary while the signal is used to estimate the noise level. Secondly, the output probabilities of audio and visual speech recognizers are normalized respectively before applying the final integration step using normalized output space and estimated weights. We evaluate the performance of our proposed method via Korean isolated word recognition system. The experimental results demonstrate the effectiveness and feasibility of our proposed system compared to the conventional systems.

In this paper we proposed a modified reliability function for improving bimodal speaker identification(BSI) performance. The convectional reliability function, used by N. Fox[1], is extended by introducing an optimization factor. We evaluated the proposed method in BSI domain. A BSI system was implemented based on GMM and it was tested using VidTIMIT database. Through speaker identification experiments we verified the usefulness of our proposed method. The experiments showed the improved performance, i.e., the reduction of error rate by 39%.

Balassian Approach of regional economic integration has been mainly aimed at improving conditions for regional trade since 1960s. After the financial crises of the late 1990s, however, the theoretical approach to regional integration will have to be a different one as regionalism have to offer enhanced protection against crises. The aim of this paper, above all, is to provide a theoretical framework for the emerging new monetary regionalism. Regions that wish to strengthen their co-operation in monetary and financial affairs today have the option of monetary regionalism without trade agreement. East Asian region will become an increasingly important domain within which to explore enhanced protection against financial crises. And as Korea seems to play a crucial role in building regional integration among ASEAN＋3(Korea, China and Japan) countries, alternative policy for Korean economy to be the North-east Asian Economic Base need to be schemed on the basis of Balassian as well as monetary regionalism.

A new GPS receiver correlator for the deeply-coupled GPS/INS integration system is proposed in order to the computation time problem of the Kalman filter. The proposed correlator consists of two early, prompt and late arm pairs. One pair is for detecting data bit transition boundary and another is for the correlator value calculation between input and replica signal. By detecting the data bit transition boundary, the measurement calculation time can be made longer than data bit period. As a result of this, the computational time problem of the integrated Kalman filter can be resolved. The validity of the proposed method is given through computer simulations.

근래에 과학교육과정의 개혁에서 쟁점화 된 내용이 무엇인지 알아보기 위해 ERIC 자료에 수록된 논문을 중심으로 조사하였다. 과학교육과정 개혁에 관련된 논문수는 70년대부터 시작하여 90년대 말에는 최고에 이르고 있기 때문에 분석 대상 논문을 최근 10년간의 132편으로 하였다. 두 편이상의 논문이 수록된 18종의 잡지에 전체의 약 66% 의 논문들이 보고되었다. 개혁의 쟁점들을 '개혁 주제', '개혁 소개', '개혁 비판과 전망' 으로 분류하였고, 개혁 주제는 구체적으로 '교사', '과학적 소양', '통합과 교수', '개혁 과정' 으로 구별되었다. '교사'관련 내용은 주로 교사들의 믿음과 신념에 대한 것이고, '과학적 소양'은 소양개념 정의의 불확실성, '통합과 교수'는 통합의 어려움과 관련된 교수 문제, '개혁 과정'은 개혁 참여 인사들의 개인적이거나 집단적 힘의 조정 문제, '비판'은 과학교육 기준의 현장 구현과 과학의 본질에 관련되어 있음이 밝혀졌다.

The spatial separation of male's and female's area due to the law of 'Naeoei' is one of the trademark features of residence by the building principle of 'Confucianism' in the upper class house in the late of the Chosun Dynasty. Thanks to modernized agriculture and commerce, the residence of 'Sinheung-Yangban' developed. And they were influenced by the economic and living characteristics than traditional custom. So the residence of 'Sinheung-Yangban' is very important in terms of the course of modernizing of the korean traditional residence. Researcher figures out the influences of the law of 'Naeoei' in residence and the characteristics of male's and female's field in terms of daily life with investigating the residence of 'Sinheung-Yangban' as the upper class house in the late of the Chosun Dynasty. Through this, the goal of this study is to find the properties of male's and female's field of upper class houses in the late of the Chosun Dynasty. With this study, the followings are the characteristics of male's and female's spatial composition of upper class houses in Gyong-gi Province in the late of the Chosun Dynasty. First, the traditional law of 'Naeoei' plays a primary role as the principle of building of upper class houses in Gyong-gi Province in the late of the Chosun Dynasty. With a natural result, there is a clear spatial separation as the male's and female's social role. Second, 'An-Chae' and 'Sarang-Chae' as male's and female's living space are separated physically, but real living life tends to be syntagmatically made with 'An-Madang' as the center. Third, spatial integration of 'An-Madang' as the center results in the development of architectural connection factors of 'An-Chae' and 'BaKat-Chae' adjoining 'An-Madang', facing 'Toei-Gan', 'Maru', and 'door'. Forth, the boundary of male's and female's areas is relatively clear between dwellers and visitors, but on the other hand, the separation of male's and female's spaces between family members has little significance.

The goal of this research is to find the difference between F. Gehry's museum architecture's extremely abstract and chaotic space composition and that of other architect's. Gehry's four museum architectures built from late 1980s to 2000 were selected for analysis. Four more museums, built in the same era with the size of that (atypical) museums, were selected for comparative studies. Space Syntax, a quantitative analysis method for spatial configuration, is used to find the characteristics of internal spaces. The Result shows that Gehry's museum architectures' connectivity is 0.375 times bigger and integration is 0.731 times smaller than the compared museums. High connectivity suggests that their visitors could take diverse routes. Low integration implies that their routes are less efficient than the compared museums overall. Their intelligibility is slightly higher than the other museums. This means their visitors have comparatively high understanding of the internal space.

The purpose of this study was to examine the effects of sensory integration therapy (SIT) on gross motor development and respiratory function of cerebral palsy children. The design of this study was one-group pre-and post-test design. Subjects of the study were arbitrarily chosen based on predetermined selection criteria among the cerebral palsy children who were treated as out-patients at one rehabilitation hospital in Kyunggi-do. The study was conducted between early April and late July in 2000. Twelve children were in the experimental group. A five-step SIT program was devised from a combination of SIT programs suggested by Ayres(1985) and Fink(1989), and an author-designed SIT program for cerebral palsy children. The experimental group was subjected to 20 to 30 minutes of SIT per session, two sessions a week for ten-week period. Collected data were statistically analyzed by SPSS PC for Wilcoxon signed rank test, and paired t-test. The results were as follows: 1. In gross motor development, post-experimental gross motor scores were higher compared to pre-experimental scores with statistical significance. 2. In respiratory function, post-experimental forced capacity vital scores were higher compared to pre-experimental scores with statistical significance. In conclusion, SIT was found to be effective in gross motor development and respiratory function. But, for the more effectiveness of SIT on gross motor development and respiratory function, further studies employing longer-time experiments are recommended.
