Purpose: The aim of this study is to identify the influence of visual and hearing impairment on the activities of daily living of community dwelling elderly. Methods: Data were collected by home visiting interviewers from 452 older people aged 65 years or older living in community. Resident Assessment Instrument MDS-HC(2.0version) was used for data collection. Data analysis for descriptive statistics, Chi-square test and multiple regression was made by SAS 6.2 Results: 34.7% of the subject had hearing impairment and 64.3% had visual impairment Among IADL. one half of them were dependent in ordinary house work and meal preparation. In the case of ADL. 13.9% of subjects were dependent in bathing and 8.9% in personal hygiene. There was significant difference in IADL performance by visual and hearing impairment On the other hand, ADL performance showed the significant difference. only in the case of hearing impairment. As the result of input of visual and hearing impairment in the process of regression. variances were increased from 3% to 11%. Conclusions: Large proportions of older people living in the community have visual and hearing impairment. It could be confirmed that hearing and vision were significant factors influencing on IADL performance of older people. Intervention and support policy for elderly needs to focus on improvement of visual and hearing impairment.

The purpose of this study is to present basic data that can express beautiful silhouette by studying visual effect that depend on waist position of basic pants and the change of round belt width and analyzing the study of visual effect of the pattern design as well as the effect of design component. The stimuli are 21 samples: 7 variations of the location of the waistline and 3 variations of the width of the belt. The data has been obtained from 35 fashion design majors. The data has analyzed by frequency, factor analysis, anova, scheffe's test and the MCA method. The visual effects by the location of waistline and the width of belt are composed of 3 factors : horizontal direction factor, vertical direction factor and flexuosity factor. In these factors, horizontal factor is estimated by most important factor. Visual effect is positive when belt width widens as the location of waist line goes down to position of low belt. And in case the location of waist line is in the position of natural waist belt and low rise belt, belt of 3.2cm width is effective visually. The interaction effects between the location of the waistline and the width of the belt have significant differences in all factors. Factor that appears in visual effect of basic pants can be evaluated differently according to pattern of pants and characteristic of body shape. So we may receive better visual assessment if we consider the location of waist belt and width of belt in side of visual effect and image, when we produce pants giving variety to crotch depth.

In this paper, a development of the sensor fusion algorithm for a visual control of mobile robot is presented. The output data from the visual sensor include a time-lag due to the image processing computation. The sampling rate of the visual sensor is considerably low so that it should be used with other sensors to control fast motion. The main purpose of this paper is to develop a method which constitutes a sensor fusion system to give the optimal state estimates. The proposed sensor fusion system combines the visual sensor and inertial sensor using a modified Kalman filter. A kind of multi-rate Kalman filter which treats the slow sampling rate ...

This study was designed to grasp the knowledge and practice the level about visual impairment protective care of the primary school students and also analyse the state of visual impairment. The subjects of this study ware 347 students composed of 456 boys and 391 girls in primary school students. The data were collected by questionaire developed for the purpose of this study which has been made through studying references. These were carried out from the 10th to 30th of June 1992. Analysis of the data was done utilizing SPSS for percentage, mean, S.D., T-test., ANOVA and Pearson's Correlation Coefficient. The major results obtained from this study were as follows: 1. The level of the knowledge about visual impairment protective care was in intermediate range (mean on 20 point scale of 12.34, with O=definitely no), but low in aspects of preventive care for overwork of eye (mean on 5 point scale of 2.67). 2. The level of the practice about visual impairment protective care was intermediate range (mean on 20 point scale of 12.34, with O=definitely no), but low in aspects of preventive care for overwork of eye (mean on 5 point scale of 2.58). 3. Significant variables influencing knowledge of visual impairment protective care were sex (p<0.01) and grade (p<0.001). 4. Significant variables influencing practice of visual impairment protective care was living area (p<0.01). 5. Correlation between knowledge and practice: Those who have more knowledge score have more practice score (p<0.001). 6. vision impairment state 1) Student with subnormal in 0.9 or less were 26.3% in left eye and 28.4% in right eye. 2) Student with subnormal in 0.6 or less were 11.9% in left eye and 10.9% in right eye. 7. Vision impairment programs 1) Males are slightly higher in the degree of visual impairment than females. 2) Visual impairment were increased in accordance with the increase of grade. 3) Urban students are higher in the degree of visual impairment than rural students, but these seem to have no statistical meaning.

In order to comply with revised national regulationson radiological protection and to implement recent nuclear data and dose conversion factors, KOPEC developed a new point kernel gamma and beta ray shielding analysis computer program. This new code, named VisualShield, adopted mass attenuation coefficient and buildup factors from recent ANSI/ANS standards and flux-to-dose conversion factors from the International Commission on Radiological Protection (ICRP) Publication 74 for estimation of effective/equivalent dose recommended in ICRP 60. VisualShieid utilizes graphical user interfaces and 3-D visualization of the geometric configuration for preparing input data sets and analyzing results, which leads users to error free processing with visual effects. Code validation and data analysis were performed by comparing the results of various calculations to the data outputs of previous programs such as MCNP 4B, ISOSHLD-II, QAD-CGGP, etc.

Computerized visual database construction of architectural precedents has just begun in some research institutes in the world. In Korea the first visual database has shown its testl version by S architectural design firm in september 1996. In this article the author discusses the historical contexts and the recent computerization cases, the traits, the uses and the limits of architectural visual database system of precedents. The forms and contents of data fields in two cases are compared with a focus on the description of architectural traits of each data entry. Compared to the KIA format, the S database has better performance for architectural design reference because it collects more pictures and drawings and larger texts for the field of architectural chracteristics. But this latter also is constrained by its capacity of memory and so lacks the reciprocity of the DOORS in the Graduate School of Design, Harvard University. A visual database system which has more flexible allocation of memory and respondent with the users is yet to be prepared. But this system also should be maintained by some experts in architectural history, theory and criticism, because their knowledge is essential for selection of precedents and revision of the data description. A full-fledged electronic visual database in architecture will not only save much effort for the architect, but also will change the architects' design behavior. Nevertheless this does not mean the automatic promotion of architects' creativity.
