This thesis examined interest and elucidation of Confucian scholars during the Chosun dynasty on the theory of self-cultivation. Taiji is the ultimate notion that surveys existence and value, however, the concern on the Taiji during the Chosun period lies more on the cultivation of mind. Confucian scholars understand the human world as a place for moral completion. Therefore, the self-cultivation theory of Confucianism rises against the disciplines of Taoism and Buddhism which are away from daily lives. And it also makes theoretical basis on the elucidation of Taiji distinguished from Taoist and Buddhist disciplines. The Confucian scholars in the Chosun dynasty saw Taiji as actual truth [實理] penetrating inside and outside and at the same time sincerity. On the discussion on "mind becomes Taiji[心爲太極]", they recognize taiji as a center supervising everything, human ultimate[人極], mind of the Way[道心]. The Confucian theory intending to comprehend tai-chi as a center of silent and stable mind, accepts methods of being calm, sitting in meditation, and breathing exercise at the time of before issuance[未發] This is reinterpreting the discipline methods of Taoism and Buddhism reasonably and including them as the parts of Confucian jing[敬] study.

Natural synthesis of real and virtual images is a key technology in mixed reality. For this purpose, we propose an efficient dense disparity estimation algorithm and a synthesis algorithm considering features of stereo images. Dense disparities are estimated hierarchically from the low to high resolution images. In the process, the region-dividing-bidirectional-matching algorithm makes matching process efficient and keeps the reliability of the estimated disparities, and dense disparities are assigned considering edge information. finally, mixed reality stereo images are synthesized by comparing depth data of real and virtual Images. Computer simulation shows that the proposed algorithms estimate very stable disparity vectors with sharp edge and synthesize natural stereo mixed reality images.

To search the minimum structural requirement of tricyclic isoxazole analogues (1~30) as new class potent antidepressant, thee-dimensional quanti- tative-structure relationship (3D-QSAR) models between substituents ($R_1{\sim}R_5$) of tricyclic isoxazoles and their antidepressant activity against medetomidine-induced loss of righting were performed and discussed quantitatively using comparative molecular field analysis (CoMFA) and comparative molecular similarity indies analysis (CoMSIA) methods. The correlativity and predictability ($r^2$=0.484 and $q^2$=0.947) of CoMSIA-2 model were higher than those of the rest models. The inhibitory activity against medetomidine-induced loss of righting was dependent on electrostatic field (43.4%), hydrophobic field (35.3%), and steric field (21.2%) of tricyclic isoxazoles. From the CoMSIA-2 contour maps, it is predicted that the antidepressant activity of potent antidepressants against medetomidine-induced loss of righting will be able to increase by the substituents ($R_1{\sim}R_5$) which were in accord with CoMSIA field.

We have proposed BIST method and circuit for embedded 16M SDRAM with logic. It can test the AC parameter of embedded 16M SDRAM using the BIST circuit capable of detecting the address of a fail cell of a 16M SDRAM installed in an Merged Memory with Logic(MML) generating the information of repair for redundancy circuit. The function and AC parameter of the embedded memory can also be tested using the proposed BIST method. The total gate of the BIST circuit is approximately 4,500 in the case of synthesizing by $0.25\mu\textrm{m}$ cell library. and verify the result of Verilog simulation. The test time of each one AC parameter is about 200ms using 2Y-March 14N algorithm.

최근 사이버교육의 필요성이 대두됨에 따라서 초 중등에서는 사이버가정학습체제를 도입하게 되었다. 하지만 사이버가정학습은 학생의 자발성에 기초하여 학습이 이루어지기 때문에 성공적인 운영을 위해서는 학습자의 참여도를 높이는 것이 중요하다. 이에 본 연구에서는 학습자의 참여도와 관련된 변인이 무엇인지를 밝혀보고, 이를 통해 학습자의 참여도를 높이기 위한 방안을 제안해 보았다. 학습자의 참여도와 관련있는 변인은 다음과 같다. 첫째, 학습자 내적변인 중 인지적 성향, 정좌소양수준, 자기주도적학습력, 참여목적, 사이버가정학습에 대한 인식이었다. 둘께, 학습자 외적변인 중 사이버가정학습장, 사교육투자시간, 학급담임의 내용확인도, 이용의 편의성이었다 셋째, 사이버교수활동 중 상호작용성, 과제제시빈도, 학습상담유형, 보상이었다. 넷째, 학부모변인 중 참여인지, 도움도, 내용확인 정도가 참여도에 유의한 영향을 준다고 나타났다. 이상과 같은 결과에 비추어 다음과 같은 방안을 제안해 보았다. 콘텐츠 측면에서 살펴보면, 다양한 양질의 콘텐츠가 제공되어야 한다. 콘텐츠 내에서 학생간이 교류가 이루어질 수 있어야하며, 정보탐색이나 정보교류를 이용한 학습문제나 과제가 제시되어야 한다. 운영상의 측면에서 살펴보면, 온라인과 오프라인의 교류와 협력을 위한 장이 마련되어야 하며, 시스템 환경을 최적화해야한다. 과제물도 일괄 처리할 수 있는 시스템이 요구되며, 가정과 사이버가정학습의 연결을 위한 시스템이 필요하다. 장애처리전담반의 운영도 요구된다. 필요한 기능을 중심으로 한 가벼운 시스템으로 구축해야 하며, 상담시스템의 구축이 필요하다. 법적 제도적 측면에서 살펴보면, 가정, 학교, 지역도서관 등에 사이버가정학습을 할 수 있는 장소가 마련되어야 한다. 학습자의 참여도에 대한 적절한 보상이 필요하다. 사이버가정학습을 학교수업의 일부분으로 인식할 수 있도록 제도적 뒷받침이 요구되며, 학부모 튜터제 도입도 요구된다. 이상과 같은 대안들을 신중히 고려하여 차근차근 준비해 간다면 앞으로의 사이버가정학습은 무한한 발전을 계속해 나갈 수 있을 것이다.

Dyskinesia can occur as a neurological abnormality due to stroke, and its incidence in stroke patients is reported to be about 1%. It is possible to classify dyskinesia into one of the morphologic types already classified clinically. However, a specific type of dyskinesia can occur; one which does not fall into the existing morphologic types. We experienced such a case of specific type dyskinesia, which couldn't be classified into the existing classification system. A 50-year-old man visited our hospital due to rhythmic dyskinesia of the right hand, which appeared during the resting state, and had developed one month after left subcortical infarction. Flexion and extension movements of the fingers at 3Hz appeared due to the impatient impulse to move. However, this abnormal movement could be easily suppressed under the patients will. We suggested that the abnormal movement was similar to akathisia from the fact that it occurred due to the internal desire to move and that the patient could suppress dyskinesia. However, the rhythmic tendency and lack of medication history of antipsychotics suggested that the movement was not the typical form of akathisia. The present case may represent a new clinical type of movement disorder developed after stroke. Considering the clinical pattern of the present case and following a review of the literature, we believe that it can be labeled, post-stroke rhythmic akathisia.

In this study, we investigate the feasibility of modeling entire image strips that has been acquired from the same orbital segments. We tested sensor models based on satellite orbit and attitude with different sets(Type1 ~ Type4) of unknowns. We checked the accuracy of orbit modeling by establishing sensor models of one scene using control points extracted from the scene and by applying the models to adjacent scenes within the same orbital segments. Results indicated that modeling of individual scenes with 1st or 2nd order unknowns was recommended. We tested the accuracy of around control points, digital map using the HIST-DPW (Hanjin Information Systems & Telecommunication Digital Photogrammetric Workstation) As a result, we showed that the orbit-based sensor model is a suitable sensor model for making 1/25,000 digital map.

In audio coding, SBR technology synthesizes the high-bands using patched time-frequency information from low-bands and the correction parameters, Since SBR transmits only correction parameters for high-bands, it provides a low-rate coding of high-bands, and is used as a core module of MPEG-4 HE-AAC, SBR was originally designed for audio signal and its performance for speech signal tends to decrease, and the major reason is an excessive noise floor in high-bands which is caused by incorrect tonality computation, In this paper, a new method to determine noise floor level in an adaptive fashion according to the speech characteristics is proposed in order to solve the problem of SBR for speech signal, The proposed method maintains the compatibility with the standard SBR, and the subjective performance evaluation shows that the proposed method improves the SBR performance especially for male speech signal compared with the standard SBR.
