This study tried to search for solutions of present problems in architecture through interdisciplinary study which includes biology, literature, aesthetics, and psychology, and set up two models composed of the nature and the human perception which contemporary architecture has problems on. By nature-oriented approach through biology and romanticist literature, the five types of organic principles which could be obtained from structure and order in natural system and by human perception-oriented approach through aesthetic theory of Harold Osborne and perceptual and cognitive psychology the structure and order of perceptual arousal, perceptual balance, and perceptual order in human cognition based on perceptual appropriateness could be found. The unified and organic framework of architectural composition must be considered through a deductive and inductive study as this study was approached. The results of the present study can be applied to construct human-oriented design principles and factors in architectural space and form, and better environmental quality.

An auditory-perceptual evaluation has long been utilized in assessing dysarthric speech. The process involves subjective judgement and the results might vary depending on clinical experiences or training of listeners. This study aimed to investigate reliability of the auditory-perceptual evaluation of 22 multi -dimensional variables on 6 patients with Parkinsonian speech disorders. Listeners were divided into two groups: one consisted of 6 speech therapists with clinical experiences for three years or more, and the other 6 graduate students without any previous clinical background. The results showed that the former evaluated dysarthric speech with higher inter-rater and intra-rater reliabilities than the latter. Furthermore, such speech variables as 'precise consonant: 'speech intelligibility: and 'SMR regularity' were more influenced than others by clinical experiences. We, therefore, postulated that a reliable auditory-perceptual evaluation of dysarthric speech may require adequate amount of clinical training of listeners.

The perceptual presentation of interior design is to represent an interior space planned by a designer as if people see it in reality. The perceptual presentation methods that have developed are perspectives, full-scale models, small-scale models, photography of models, video taping of models, computer images, computer animation, and virtual reality. The purpose of this study is to investigate limits of those perceptual presentation methods according to their characteristics. The methods have characteristics that are either static or dynamic and either monoscopic or stereoscopic. In terms of representing interior spaces and perceiving interior spaces, the dynamic characteristic is more helpful than the static characteristic because the dynamic characteristic provides consecutively changing views of interior spaces when people walk around within the spaces. The stereoscopic characteristic is more helpful than the monoscopic characteristic because the stereoscopic characteristic provides the binocular depth perception. Full-scale models, small-scale models, virtual reality that have dynamic and stereoscopic characteristics, are most effective. The next effective methods are video taping of models and computer animation that have dynamic and monoscopic characteristics. The last effective methods are perspectives and photography of models that have static and monoscopic characteristics. But the most effective methods can not be said that those are perfect because each of them still has limits. Designers have to consider the limits of each perceptual presentation method to find a way that shows their designs most effectively. To develop the perceptual presentation methods of interior design, researchers should focus on the helpful characteristics that are dynamic and stereoscopic.

눈 운동과 관련된 공간지각 왜곡이 다양하게 보고 되었는데, 대부분의 공간지각 왜곡이 두 눈이 동일한 방향으로 움직이는 눈 운동에 국한되어 연구되었다. 이형철, 감기택, 김은수와 윤장한 (2002)은 두 눈이 각기 반대 방향으로 움직이는 원근방향 추적 눈 운동 동안에 시공간적인 중첩패턴에 의해 정의되는 대상의 경사가 체계적으로 왜곡되어 지각된다는 것을 보고하였다. 본 연구에서는 배경과 대상이 상이한 명도를 갖는 반투명 대상의 경사가 원근방향 추적 눈 운동에 의해 왜곡되어 지각되는지를 검증하였고, 동시에 목표대상의 주위에 존재하는 참조자극이 경사지각 왜곡에 미치는 영향을 검증하였다.

Recent investigation of acoustic correlates of Korean stop manner contrasts has reported a diachronic transition in Korean stops: young Seoul speakers are relatively more dependent on the F0 characteristics of the stops than on the VOT characteristics in aspirated and lenis stop distinction. This finding has been examined against tonal dialects of Korean and the results suggested that the speakers of tonal dialects are not sharing the transition. These results also suggested that F0 function for segmental stop classification interferes with the function for lexical tone classification in their tonal speech. The current study investigated these findings in terms of perception. Perceptual behavior of Seoul and Busan speakers of Korean was examined in a comparative manner through the measurement of perceptual cue weight of F0 and VOT in particular. The results from regression and correlation analyses revealed that Busan speakers are closer to older Seoul speakers than to younger Seoul speakers in that the cue weight for VOT and F0 were comparable in the aspirated-lenis stop distinction. This result was in contrast to the perceptual behavior of younger Seoul speakers who showed clear dominance of F0 over VOT for the same distinction. These findings provided perceptual evidence of the dual function of F0 for segmental and lexical distinctions in tonal dialects of Korean.

태그는 위치정보가 없기 때문에 리더의 식별자를 위치정보로 사용하지만 비연속적인 심볼형 정보이다. 따라서 태그 이동 궤적간의 근접성을 정의하는 것이 어려우며 사용자 질의 처리시 비효율적이다. 본 논문에서는 태그 위치를 표현하기 위하여 인식공간을 정의하고 인식공간 근접성을 제안한다. 인식공간 근접성은 정적 인식공간 근접성과 동적 인식공간 근접성으로 구성되며 이를 이용하여 태그 궤적 간의 근접성을 측정하고 효율적인 색인을 구축할 수 있다. 제안한 태그 이동 궤적 근접성 함수를 평가하기 위해 태그 색인 기법인 IR-tree와 이동체 색인 기법인 $R^*$-tree를 대상으로 성능평가 실험을 수행하였다.

Objectives : Perceptual experiences have a causal relationship with reality. If there exists something corresponding to acupoints, there should be perceptual experiences for that something. The purpose of this study is to identify and to analyze the perceptual experiences for acupoints within 『LingShu·BenShu』. Methods : First, we briefly propose a perceptual anatomy in order to describe the perceived human body parts, and their perceived directions and places. Second, we analyze the ways of identifying acupoints in the original text of 『LingShu·BenShu』. Results : From 『LingShu·BenShu』, the procedures of identifying total 64 acupoints were recognized. It was clarified that they are by way of visual and haptic explorations in body regions and partial regions. Conclusions : Perceptual explorations for acupoints follow three major principles: of gradual narrowing down, of determination of direction or place, of relative distance. At the final stages, categories of form and location are encountered by observers. The forms have either concavities or convexities. They are determinate indicators of where acupoints are, while the locations are indetermanate. Haptic forms of acupoints are newly discovered from textual analysis with perceptual anatomy. These properties will shed new light both on study of acupoints and on study of meridians.

주의를 기울이지 않은 배경자극의 정서가가 표적자극의 지각처리에 미치는 영향을 알아보기 위해 정서적 그림자극(IAPS) 위에 6개 글자들을 함께 제시하고서 실험참가자들에게 특정 글자를 탐지하도록 요구하였다. 글자탐지의 난이도를 달리하여 지각부담을 조작하였는데, 정확율과 반응시간 모두에서 저부담조건이 고부담조건보다 빠르고 정확하였다. ERP 분석 결과, 정서자극 없이 글자탐지만 수행한 통제조건의 경우 후측 시각영역에서 P1과 N1 성분에서 지각부담효과가 관찰되었다. 실험조건에서는 정서가와 지각부담의 상호작용이 후측 시각영역의 N1에서 관찰되었는데, 특히 중립정서보다 부정정서에서 고부담조건과 저부담조건간 진폭 차이가 더 크게 나타났다. 배경자극이 부정적인 경우 중립적인 경우보다 주의용량을 더 소모함으로써 지각부담효과가 더 컸던 것으로 판단되는데, 이는 주의집중 받지 않은 정서자극이 자동적으로 처리되어 표적자극의 초기 지각처리에 영향을 미친다는 것을 시사한다.

We investigated the perceptual structure of Korean consonants by analyzing the confusion among consonants in various vowel contexts. The 36 CV syllable types combined by 18 consonants and 2 vowels (/i/ and /u/) were presented with masking noises or in degraded intensity. The confusion data were analyzed by the INDSCAL (Individual Difference Scaling), ADCLUS (Additive Clustering) and the probability of the transmitted information. The results were compared with those of a previous study with /a/ vowel context (Bae and Kim, 2002). The overall results showed that the laryngeal features-aspiration, lax and tense-are the most salient features in the perception of Korean consonant regardless of vowel contexts, but the perceptual saliency of place features varies across vowel conditions. In high vowel (front and back vowel) contexts, sibilant consonants were perceptually salient compared to in low vowel contexts. In back vowel contexts, grave (labial and velar) consonants were perceptually salient. These findings imply that place features and vowel features strongly interact in speech perception as well as in speech production. All statistical measures from our confusion data ensured that the perceptual structure of Korean consonants correspond to the hierarchical structure suggested in the feature geometry (Clements, 1991). We discuss the link between speech perception and production as the basis of phonology.
