This study aims at the observation of some analytical levels-especially those of syntactico-semantical- of the visual expressions in general. As far as the syntactical parts are concerned, there were two steps to be approached. One is to select the paradigms according to the Saussure-Hambidgean suggestions, the other to derive syntagmas from what is called the 'chaos-system', one of nonlinear dynamics. In result, paradigms could be acquired 5 sorts with its so many varieties, as visual templates(VT), supplemented by their reciprocals(R) and complements(CLE), and syntagmas five orbits from each constant c=0 to c=10. In additional, in connection with semantic parts, the study introduced a Gremasian model of discourses and narratives for the interpretation of signifiers. By this, we could cover the conjunctive relationships(+) and the disjunctive(-) of the whole structure of visual expression. Finally, we certified that the above could be fully approved in terms of recent worldly cognitive scientic psychological discoveries.

This study has proposed visual-feature extraction methods for each band in wavelet domain with both spatial frequency features and multi resolution features. In addition, it has brought forward similarity measurement method using fuzzy theory and new color feature expression method taking advantage of the frequency of the same color after color quantization for reducing quantization error, a disadvantage of the existing color histogram intersection method. Experiments are performed on a database containing 1,000 color images. The proposed method gives better performance than the conventional method in both objective and subjective performance evaluation.

The purposes of this study are to consider characteristics of 'movement expression' that are not discovered in preceeding design studies in order to suggest 'movement expression' as a design formative principal and to make clothes which follows this idea. For the method of this study I used various literature about 'movement expression' as theoretical background and analyzed modern clothing in which 'movement expression' is expressed by collecting magazines including foreign collections from 1989 to 2004 and searching the internet. The results obtained from this study is as follows. First, clothing in which 'movement expression' is expressed removes monotony and tedium of clothing design, provides visual interest and satisfaction for clothing, and delivers designers' concept effectively by attracting a gaze quickly. And It is suggested a new division of 'movement expression' through analysis of the 'movement expression' expressed in clothing. It included the intentional movement by wearers, which is the 'movement expression' of broader meaning such as changes of form or position by a certain operation and changes of existence or function. This movement is not fixed and repeated but changes continuously. As a result of including the design expressing the intentional movement by wearers, one's own personality can be expressed more effectively. It is presented a design which has changeable movement expression continuously.

Modern people communicate in a digital space without being limited by physical space and time. On the internet, people's desire for self-expression is getting bigger, and the most common self-expression tool is characters. Characters are visual materials to express human thoughts and desires. This study is a method to positively express the viewer's self in an interactive Hangeul system. The proposed system produces new formative shapes and meanings of Hangeul through the process of deconstructing and reconstructing the characters. Immediate character transformations that are synchronized with the motion of the viewer act as a tool of self-expression by inducing the viewer's active interaction repeatedly. Therefore, the proposed interactive Hangeul is more than enough to be used as a new graphic tool beyond the text to be read, and it is highly likely to develop into cultural contents using it.

The purpose of this study was to identify the effect on improvement of the Activity of Daily Living (ADL) and decrease the cognitive function and agitation behaviors by reminiscence with audio-visual stimulation for senile dementia. The quasi-experimental design was used in this study. Subjects were 26 with mild senile dementia who were cared for at a Day Care Center for Dementia in Seoul. The data were collected from March to July, 1999. Subjects were divided into three groups : Control Igroup with 10 subjects, reminiscence group(Control II group with 8 subjects), and reminiscence with audio-visual stimulation group(experimental group with 8 subjects). The Control I group got routine care as usual. Control II group participated in reminiscence sessions for one hour a day, five times a week , for a period of 4 weeks. The experimental group participated in reminiscence with audio-visual stimulation sessions for one hour a day, five times a week, for a period of 4 weeks. Instruments of this study were color photography with sound that was developed through an open questionnaire about events, objects, humans in action and animals that 100 Korean elderly over 60 would like to memorize. This was referred from the Sensory Stimuli Package by Namazi and Haynes(1994). The effects of treatment was evaluated through MMSE-K by Kwon & Park(1989). Also the Brief Cognitive Rating Scale(BCRS) by Reisberg et al(1983) for the cognitive function, through Agitation Inventory by Cohen- Mansfield and Colleague(1989) for behavioral response and through the Rapid Disability Rating Scale-2(RDRS-2) by Linn & Linn(1982) for the activity of daily living respectively. Data analysis was done using SPSS for $\chi$2- test, ANOVA, repeated measures ANOVA. The results were as follows : 1. Reminiscence with audio-visual stimulation did not improve cognitive function for senile dementia, but significantly improved verbal expression, the subscale of cognitive function. 2. Reminiscence with audio-visual stimulation reduced agitation behavior of experimental group significantly, but there was no significant difference between groups. 3. Reminiscence with audio-visual stimulation did not significantly effect the activity of daily living after treatment. In conclusion, it was shown that the reminiscence with audio-visual stimulation was an effective therapy to improve verbal expression and to reduce agitation behaviors of senile dementia. Further research with more indepth approach is needed, considering characteristic and level individualized for each senile dementia.

Embryonic lethal abnormal visual (elav) is a lethal gene in Drosophila inducing the abnormal development and function of nervous system. We cloned a Bm-elav gene by bioinformatics and biological experiment, based on sequence of ELAV protein and dbEST of Bombyx mori. The full-length of Bm-elav cDNA is 1498 bp, contains a 906 bp open read frame (ORF) encoding a precursor of 301 amino acid residues with a calculated molecular weight of 34 kDa and pI of 8.99. Bm-ELAV protein precursor contains three RNA recognition motifs (RRM) in $24{\sim}91$, $110{\sim}177$ and $222{\sim}295$ bit amino acid residues respectively, and belongs to RNA-binding protein family. Bm-ELAV shared varying positives, ranging from 56% to 60% (Identities from 41% to 45%), with RRM from other species of Xenopus tropicalis, Apis mellifera, Tribolium castaneum, Branchiostoma belcheri and Drosophila. Gene localization indicated that Bm-elav is a single-copy gene, gene mapping within 12-chromosome from 7916.68 knt to 7918.16 knt region of nscaf2993. Spatiotemporal expressions pattern analysis revealed that Bm-elav expressed higher in most tested tissues and developmental stages in whole generation, such as silk gland, fat body, midgut, hemopoietic organ and ovary, but almost no expression in terminated diapause eggs. This suggested that the expression of Bm-elav in early developmental embryonic stages might induce abnormal development like in Drosophila. Cloning of the Bm-elav gene enables us to test its potential role in controlling pests by transferring the gene into field lepidopteran insects in the future.

본 연구는 시각작업기억에 저장이 요구되는 얼굴 자극이 보유한 긍정적, 부정적 그리고 중립적 정서가 기억 정확성에 미치는 영향을 조사하였다. 참가자들은 유쾌, 불쾌 및 무표정의 세 가지 표정 유형 중 하나가 무선적으로 부여된 얼굴들의 표정을 기억한 후 잠시 후 제시된 검사 얼굴들에 대한 대조를 통해 기억항목과 검사항목 간 얼굴 표정의 변화 유무를 보고하였다. 얼굴 표정의 변화에 대한 탐지정확도를 측정한 결과 기억항목의 노출시간이 500ms이었을 경우, 긍정적 표정을 보유한 기억항목에 대한 변화탐지는 부정 및 중립 표정에 비해 상대적으로 정확했다. 반면에 노출시간이 1000ms로 연장되자 이러한 차이는 관찰되지 않았다. 이러한 결과는 긍정적 정서가 시각작업기억의 정확성을 향상시킬 수 있음을 의미하며, 특히 긍정적 정서에 의한 기억 촉진 효과는 기억 표상 형성에 있어서 요구되는 시간이 상대적으로 촉박한 경우에 나타남을 의미한다. 따라서 본 연구는 작업기억과 정서간의 관계를 규명하기 위하여 비교적 단순한 과제인 변화탐지과제를 사용하여 긍정적 정서가 시각작업기억 표상 형성의 효율성을 향상시킨다는 것을 발견했다는 점에서 중요한 시사점을 제공한다.

일반적인 물체와 달리 사람의 얼굴은 표정이라는 중요한 시각적 요소를 포함하고 있다. 이러한 이유로 만화가들은 빛에 의한 음영 이외에도, 장면의 분위기와 캐릭터의 특징을 효과적으로 전달하기 위해 특별한 음영을 얼굴에 그려 넣는다. 이러한 음영은 물리적으로 타당하지는 않지만 얼굴의 형태와 표정을 강조하기 때문에 얼굴 표정의 카툰 렌더링에서 반드시 고려해야 할 사항이다. 이 논문에서는 실제 만화가의 음영 표현방식에 착안하여 캐릭터 얼굴을 위한 새로운 카툰 렌더링 방법을 제안한다. 이를 위해 먼저 다양한 만화 이미지를 수집하여 얼굴의 음영표현을 분석하고, 캐릭터의 표정에 따라 카툰 렌더링을 달리 하기 위해서 음영표현 템플릿을 정의하였다. 그리고 이러한 만화가들의 음영표현방식을 바탕으로 기존의 카툰 렌더링 방법을 발전시켜 효과적으로 캐릭터의 표정을 강조하는 캐릭터 얼굴 카툰 렌더링 시스템을 구현하였다. 마지막으로 사용자평가를 통해 논문에서 제안한 방법의 유용성을 증명한다.
