  • In this paper, we explained the relation between evaluating display device and emotional image quality evaluation in human perceptual view. It is also suggested two emotional image quality evaluation method of display reflecting human visual function. One is the color space of CIECAM02 and the other is capturing moving image. It is necessary to standardize the evaluation methods of image quality based on emotional evaluation.

  • This study investigates the asymmetry effect between acoustics and perception. The examined cues are closure duration, closure voicing, VOT, release, pre-vowel duration, post-vowel duration. Five native speakers of English and 30 Korean college students participated in the present study. The results showed that high level Korean English learners parallels native speakers in their responses, while mid and low level Korean learners are substantially different from natives.

  • The purpose of this study was to investigate the relationship between Perception of self anp Clothing Interest, and to determine the difference of Clothing interest and Perception of self by the demographic variables. Perception of self was measured with Perception of self test from Choi's Perceptual Orientation Scale. Appearance, Clothing comfort, Fashion, Psychological dependence, Clothing economics were measured with items from Gurel's Study and Creekmore's for method of measuring clothing variables, items were drawn from preceding measures and, slightly modified. Data were affected from 305 purposively selectee! elderly women over sixty dwelling in Seoul by means of interview and questionnaire. For statistical analyses, frequency distribution, ANOVA, Duncan's multiple Range test, Pearson's Correlation coefficients were used. The results were as follows; 1. The three groups classified, by Perception of self were Positively Correlated to Appearance, Fashion and Psychological dependence. 2. There was partially significant difference between clothing interest and demographic variables. Education and socioeconomic status affected Psychological dependence. Demographic variables not affected Clothing comfort. 3. There was partially significant difference between Perception of self and demographic variables. Age, education, marital status and socioeconomic status affected Perception of Self. 4. There was partially significant relationships among subscales of the Clothing interest. Appearance was positively correlated to clothing comfort, Fashion and Psychological dependence, clothing comfort was positively correlated to Appearance, Psychological dependence. Fashion was positively correlated to Appearance, Clothing comfort and, Psychological dependence.

  • 가상환경을 활용한 시뮬레이션과 같은 교육, 훈련 등이 다양한 분야에 적용되고 있는 만큼 그 활용성은 무궁무진하다. 하지만 가상환경에서 훈련을 함에 있어 깊이지각의 과소추정이 존재하며, 이는 향후 훈련의 타당도에 문제가 될 수 있다. 관련 연구에서는 이를 해결하기 위해 하향식 보정방안을 적용하여 문제를 해결하려 하였으나 그 결과가 학습에 의한 효과인지 실제 지각의 변화인지에 대한 구분이 어렵다는 단점이 있다. 이에 본 연구에서는 실험결과를 통하여 공간 구성요수 중 비례가 깊이지각에 유의미한 영향을 끼치는 것을 확인하였으며, 비례와 깊이지각 단서를 함께 보정하여 실험할 경우 깊이지각 중 크기지각이 매우 정확해진다는 것을 확인하였다. 이에 본 연구에서는 깊이지각의 정확도를 높이기 위해 공간 구성요소와 깊이지각을 활용한 보정방안을 제시한다.

  • This study was the done to describe health behavior and determine affecting factors in middle aged women. The subjects of this study were 306 middle aged women, living in M city, during the period from June 28th to August. 31st 1999. The instruments for this study were Health Behavior Assesment tool developed by Kim (1998), Self esteem scale developed by Rosenberg(1965), the perceived health status scale by Lawston, et al.(1982), the Quality of life by Ro(1988), the attitude toward Climacteric symptom by Ji(1983). The data were analyzed using descriptive statistics, t-test, Pearson correlation coefficients and stepwise multiple regression. The result of this study are as follows; 1. The total mean score for Health behavior was 2.51(range 1-4). The mean scores on the subscale were 2.83 for nutrition, 2.81 for stress management, 2.71 for limitation of liking in the menstrual group, health behavior was 2.64. The mean scores on the subscale were 2.98 for nutrition, 2.85 for stress management, 2.82 for limitation of liking, 2.80 for energy conservation in the menopausal group, 2. The mean scores for cognitive-perceptual variables in the menstrual group were perception of health status: 2.61, quality of life: 3.17, self-esteem: 2.59, and attitude for climacteric symptom: 3.02. In the menopausal group the scores were perception of health status: 2.41, quality of life: 3.10, self-esteem: 2.62, attitude for climacteric symptom: 3.06. 3. Health behavior and self-esteem(r=.269, p=.000; r=.205, p=.042), attitude for climacteric symptom(r=.192, p=.005; r=.545, p=.000), quality of life(r=.385, p=.000; r= .195, p=.050) and health behavior were correlated positively, and the perception of health status and health behavior were correlated negatively(r=.-135, p=.050; r= -.207, p=.040 ) in the menstrual group and menopausal group. 4. Perception of health status, quality of life, age, self-esteem, job and marital status explained 33.7% of the variance for health behavior in the menstrual group; self-esteem and education explained 33.1% of the variance for health behavior in the menopausal group. In conclusion, health behavior should be considered when developing nursing strategies for middle-aged women, especially when dealing with perception of health status, quality of life, and self-esteem.

  • The active noise control (ANC) technique attenuates acoustic noise in a flexible and effective way. Traditional ANC design aims to minimize the residual noise energy, which is indiscriminative in the frequency domain. However, human hearing perception exhibits selective sensitivity for different frequency ranges. In this paper, we aim to improve the noise attenuation performance in perceptual perspective by incorporating noise weighting into ANC design. We also introduce psychoacoustic analysis to evaluate the sound quality of the residual noise by using a predictive pleasantness model, which combines four psychoacoustic parameters: loudness, sharpness, roughness, and tonality. Simulations on synthetic random noise and realistic noise show that our method improves the sound quality and that ITU-R 468 noise weighting even performs better than A-weighting.

  • This study focuses on the visual effects of various neckline-haristyle combinations on the perception of face image and type. The study employed a model with oval face and examined 35 combinations made up of five necklines and seven hairstyles. Looking at various face images depending upon different necklines, in case of round, V, boat square, and high necklines, long wave hair and medium wave hair produced a feminine image of marked individuality; long straight hair that covers the forehead and medium straight hair gave an image of charm and purity as well as an image of neatness; and long straight hair short cut hair showed an intellectual image. Regarding the perceptual type of face depending upon the different necklines of round, V, square, and high, the long straight hair covering the forehead and medium wave hair had the effect of an optical illusion that made the face look short and round; and short cut hair made the face line look distinct and the face look oval and slender.

  • The purpose of this study is to identify the perceptual differences among independent elderly relative. to falls risk associated with specified environmental design factors. The sample consisted of 135 independent elderly who live in Ulsan. The data were collected by utilizing questionnaire which included demographic information, and environmental design assessments accompanied by line drawings. The data were analyzed by using SAS program. The major findings were as follows: (1) There were 35(25.9%) elderly experienced fall(s) within one year and about half of the fallers fell more than once. (2) The elderly perceived lighting is the most hazardous interior design factor related to increased risk of falls. (3) There was a significant difference among age groups on perception of lighting as interior design factors and the elderly perceived differently floor as interior design factors by their perceived health status.

  • This paper introduced a measurement method for image sticking based on human vision perception. Existing image sticking quantification method is mostly different from visible level by human perception. It takes a long time to measure image sticking which is degraded by time due to using a spot photometer, therefore many test samples could not be evaluated in a given short period of time in mass production line. However, the new measurement method in this paper is possible to evaluate a large quantity of samples in fast and high correlation with human perceptual level of image sticking.
