To be the design method supporting aesthetic ability of human, CAAD system should essentially recognize architectural form in the same way of human. In this study, visual perception process of human was analyzed to search proper computational method performing similar step of perception of it. Through the analysis of visual perception, vision was separated to low-level vision and high-level vision. Edge detection and neural network were selected to model after low-level vision and high-level vision. The 24 images of building, tree and landscape were processed by edge detection and trained by neural network. And 24 new images were used to test trained network. The test shows that trained network gives right perception result toward each images with low error rate. This study is on the meaning of artificial intelligence in design process rather than on the design automation strategy through artificial intelligence.

Floor vibrations in residence and office buildings are typically induced by heel drop and walking movement of occupants. The criteria of most vibration provisions have been developed based on the vibration caused by heel drop impact rather than walking. There may be considerable differences between the vibration characteristics induced by walking and heel drop. The effect of walking vibration was not well reflected on current provisions. In this paper, shaking table test was performed to investigate the human perception level against the vibrations due to walking and heel drop. This study attempts to compare the human Perception level of two different vibration sources. Also, this study investigates the effect of damping on a Perception level under heel drop and walking vibration.

This study examined human rights perception, cultural diversity perception, level of character perception, and influencing factors for university students in order to prepare basic data on integrated education methods of character, human rights and cultural diversity and education program models. The research questions are as follows. 1. What are university students' perceptions of character, cultural diversity and human rights? 2. What is the status of the experience of family life education on character, cultural diversity, and human rights, and is it related to the level of perception? 3. What variables affect character perception, cultural diversity perception, and human rights perception? The survey targeted 407 students at two universities in Seoul and used IBM PASW Statistics as a tool to analyze data. The study results are as follows. First, university students' character, cultural diversity and human rights perception were above average; however, empirical education is still required because they had low scores in the area of action. Second, male university students have less experience in family life education on character, cultural diversity and human rights compared to female university students. Third, it is necessary to integrate education for character, cultural diversity and human rights because the most influential factors in character perception, cultural diversity perception and human rights perception were character education. The role of family life education should be considered important because personality education in the home showed a relatively high correlation.

The purpose of this study was to explore the effect of maternal perception of children's temperament on parenting stress. The subjects of this study were 303 mothers of four to six-year-old. Evaluations of Parent and Teacher temperament questionnaire for Children 3-7 years of age(Tomas, Chess, & Kom, 1977)(korean version) was used to measure children's temperament, and PDH(Parenting Daily Hassles) was used to measure maternal perception of parenting stress. Data were analyzed by descriptive analysis, t-test, ANOVA, Peasons's Correlation and multiple regression analysis and Duncan test for post test by SPSS WIN program. The results of this study were as follows; First, the average level of maternal perception of children's temperament was the highest in the category of adaptability and the lowest in the category of threshold of responsiveness. Second, maternal perception of children's temperament was significantly different according to children's sex. Boys were perceived higher than girls for the category of activity level. Third, the degree of daily hassles was explained by adaptability, the quality of mood, and activity level relatively, while the intensity of parenting stress could be predicted orderly by adaptability, threshold of responsiveness, attention span & persistence, regularity, and activity level. Fourth, mother's daily hassles was explained 22% valiance by children's temperament such as adaptability, the quality of mood, and activity level. Future research should be done to identify the interaction of temperamental factors.

Occupants induced floor vertical vibrations may cause other occupant's annoyance and lead to social loss. To help control such floor vibrations, several criteria have been developed mostly based on human perception tests and floor vibration tests. Floor vibration is evaluated by comparison with criteria and vibration parameters of subject floor, such as frequency, damping ratio, acceleration value, vibration duration time and occurrence frequency. Three acceleration value parameters are used in criteria; peak acceleration, rms acceleration and VDV, when a floor vibration serviceability is evaluated. Meanwhile rms acceleration and peak acceleration are adopted as vibration limit value in criteria and researches of human perception for vibration. Occupants induced floor vibration is transient rather than steady state. However, rms acceleration is not reliable parameter for evaluating transient vibration. The objective of this study is to investigate the characters of human perception level according to acceleration value parameters for vibration induced by heel impacts and walking activities.

The purpose of this research was to investigate perception, knowledge, and practice level for school food hygiene and need for hygiene education with 300 students of elementary schools in Daegu. The average of correct answer percentage on knowledge about food hygiene of the respondents was 65.3%. For practice level of personal hygiene in school food, the average score was 3.75 out of 5 points. The ratio of educational experience of hygiene and dietary behaviors at home was 73.2%. Almost half of the respondents answered that 'food ingredients' should be the most hygienic. About 90% of the respondents recognized 'hand washing' had effect on prevention of foodborne illness. In addition, the respondents wanted to get the information about food hygiene from 'cooking practice at school', 'school broadcasting', 'education program on TV', and 'school newsletter' in order. These results suggest that continuous education on food hygiene for elementary school students are required and supervision to let them have proper hygiene habit is needed.

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.

This paper measured elderly consumers' perceptions of purchasing problems, and classified elderly consumers into 5 categories of purchasing problems using cluster analysis, and analyzed the relationships between the elderly consumers' perception type, socio economic variables, activities of daily living, and activities of healthy living. The data was collected from 500 elderly consumers in Ulsan Metropolitan City. Three clusters were extracted. 56.4% of the sample was included in 'redress and contract problems group', and 22.6% of the sample was included in 'less perception of purchasing problems group, and 21.0% of the sample was included in 'the perception of strong purchasing problems group. The elderly consumers' perception type of purchasing problems were related with socio-economic variables such as sex, existence of a spouse, the number of family living together, the number of children, education, the average monthly household income and allowance, activities of daily living, and activities of healthy living. The redress and contract problems group was found to be of midium level in socio-economic and health status, and included more females and less spouselessness. The perception of less purchasing problems group was found to be the highest level in socio-economic status, and included more males and less spouselessness. The perception of strong purchasing problems group was found to be at the lowest level of socio-economic status.

Human perceptional speed is different from its real speed. There is lack of research that the perceptional speed is different from real speed in 2-dimension, because most research of speed perception has concentrated on points and lines. This research investigates the effects of object size on speed perception. In this research, we used 2-D circular objects of the different size, 0.9, 1.8 and $3.6^{\circ}$. The objects moved 9.0, 13.5 and $18.0^{\circ}$ with three different speeds, 6.0, 9.0 and $18.0^{\circ}$/s. Six participants were exposed to the environment with standard scene(size: $1.8^{\circ}$, speed: $9.0^{\circ}$/s and travel distance: $13.5^{\circ}$). After the first scene, another scene in which the object had changed to different sizes, speeds and distances, was shown to the participants. A magnitude estimation method was used to construct a scale of the perceived speed level. The relationship between the perceived and the actual speed level was explained by Stevens's power law that the value was 0.978 with the exponent of 0.992. The size of object had an effect on the speed perception but travel distance was not. The perceptional speed of bigger object was lower than of smaller object. It showed that the degrees of perceptional speed decreased as size of object increased.
