Visual acuity Decrease is one of the most common symptoms of adolescents. Acupuncture method has been used for improvement of visual acuity from ancient period. But it is not sufficent to recognize underlying causes and predisposing factors of visual acuity decrease. So we investigate the common causes and factors on myopia outpatients group. We researched 992 outpatients who were treated at Department of Acupuncture & Moxibustion, National Medical Center from June 2001 to May 2002. The outpatients were classified into several groups according to visual acuity and age. Common predisposing factors of visual acuity decrease were assessed through questionnaires based on the Classics of the traditional oriental medical bibliography. The results are as follows; age distribution is 52.9$\%$ for female, 47.1$\%$ for male. The predisposing factors were ranked as poor posture(66.9$\%$), unbalanced diet(57.2$\%$), heredity(53.8$\%$), irregular diet habit(51.3$\%$) and so on. These results playa role as preliminary data in recongnition of myopia in the view of oriental medicine.

We propose two new rate control schemes to improve MPEG-2 rate control in view of visual quality when scene changes happen. Two proposed schemes are characterized by real-time and non real-time improvement to reduce the impact of scene changes. We also propose a new target-bit prediction method using spatial activity of pictures and present a simple and efficient scene change detection scheme using signed difference of mean absolute difference (MAD). Computer simulation results show that the proposed real-time algorithm effectively alleviates visual quality degradation after scene changes. The proposed non real-time algorithm gives maximum 2 dB improvement in peak signal-to-noise ratio (PSNR) at a scene-changed picture, compared with MPEG-2 rate control scheme and it shows better quality than the real-time one.

An LED sensor luminaire for visual function improvement necessitates the control algorithm for light level adjustment and the appropriate lens design. The control algorithm adapts to surround lighting condition, and thus has the advantages of energy saving and glare reduction. The multi-cell lens design improves color temperature uniformity and spatial light distribution of the luminaire. Experimental and simulated results show that this approach contributes noticeably to energy saving and color temperature uniformity of the LED sensor luminaire.

PURPOSE: The purpose of this study was to investigate the effect of balance rehabilitation training with the visual cue deprivation on gait function in stroke patients in comparison with balance training without the visual cue deprivation. METHODS: Twenty two stroke patients participated in this study. Patients were randomly assigned to one of the two balance training program with and without the visual cue deprivation. Balance training session for each group lasted 50 minutes, 3 times a week for a total of 6 weeks. Gait function was measured with the Functional Gait Assessment (FGA), the self-selective comfortable gait speed (CGS), the maximal gait speed (MGS), and the Gait Analysis System. Temporal and spatial gait parameters of each evaluation were measured before and after the balance training program respectively. RESULTS: After the program, the visual cue deprivation group improved significantly in the FGA, the CGS, the gait velocity, the step time, the step length, the stride length, and the Functional Ambulation Performance (FAP) in comparison with the balance training group with the visual cue (p<.05). CONCLUSION: The gait function of the participants with the visual cue deprivation showed more improvement after the balance training program compared to the patients group without the visual cue deprivation, Therefore, the balance training program with the visual cue deprivation may be useful for rehabilitation of patients with chronic stroke.

As an aging population has increased vastly and nuclear families have been a dominating family type in modern Korean society, the numbers of the elderly who suffer Empty Nest Syndrome and LID (Loss Isolation Depression) syndrome have been accelerated. These syndromes involve psychological instability, melancholy, and lethargy. To make the elderly get out of this phenomenon and live actively, the scheme of converting their existing house into shared housing was set as a hypothetical solution in this study. This study sets out to find out responses of the elderly to alter their own house's function in housing improvement area. A Small Workshop Panel method was used and the elderly aged 55 years upwards took part and they own a detached house in a housing improvement area that is relatively large for the elderly or the elderly couple to live alone. Through the workshop, problems that the elderly have been experiencing within their houses were looked into and responses of the elderly on altering their house to shared housing by introducing developed schematic plans. Although, the first response was negative, positive responses from the house owners were carried out when a visual support i.e. developed shared housing plan was provided. The positive response was based on the fact that subsidies from the government on house renovation and tenants matching programs are supported as shared housing could provide home owners economical support with rents and help them to feel less lonely. This is a way of relieving the elderly from being neglected and supporting them to live and age actively in their later lives. Furthermore, by providing a visual media to the elder residents in housing improvement area, their greater understandings on the development and addressing their opinions were possible. Therefore, more tools that promote elder residents' participation are needed for future housing improvement projects and an aging society.

This study was to compare multidimensional outcomes of patient's satisfaction after cataract surgery and to identify factors influencing satisfaction after operation. Patient's satisfaction was measured with three dimensions : interpersonal care, physician explanation and hospital care. Overall satisfaction was measured as means of three dimensional scores. For the study, a prospective study was performed with 389 patients who had undergone cataract surgery for either one eye or both eyes. The surgery was performed by 20 ophthalmologists who were practicing at university hospitals and general hospitals. Patients were interviewed and clinical data (the visual acuity of operated eye, visual function, symptom score and satisfaction with vision) were obtained. The doctors were questioned with self-reported questionnaire forms. Medical records were also examined to understand surgery Process. The survey was conducted before(389) and after operation(327). Alter excluding cases with incomplete data, 3n cases were enrolled In this study. Both the overall satisfaction and the satisfaction with physician explanation increased after the operation whereas the satisfaction with interpersonal care and hospital care did not change significantly. Multiple regression analysis showed that the level of education, baseline satisfaction scores and the degree of vision improvement were statistically significant variables. The preoperative lower level of education, higher level of overall satisfaction (interpersonal care, physician explanation, hospital care scores) and the more the satisfaction with vision improvement were associated with the improvement of postoperative satisfaction scores.
