To survive head-to-head competition, we should keep our labor productivities above those of other nations. However, our labor productivities are low compared to those of the developed countries. It is the well-known fact that we make up for the productivities with long work hours. Entering the line of developed nations safely and enjoying well-being age freely, we need to achieve high labor productivities without sacrificing work hours. What would be a fine solution? Back to the basics! Although it is important to enforce R&D on high-tech products, we should have so-called bluebird philosophy, being faithful to the basics and trying to find solutions at a stone's throw. Basics of basics may be unceasing improvement, establishing reasonable standard times, and maintaining them. To support going back to the basics, this thesis proposes VITAMAX, a motion and time study software. As VITAMAX stands for "Visual Improvement and Time Analysis for Maximizing Profits", it provides a simple and powerful visual tool which is useful for improving manual works and determining standard times. Since VITAMAX is based on the Microsoft Excel and VBA, it is very cost-effective and easy to use. VITAMAX may contribute to the profit increase of manufacturing companies, especially for the small and medium-sized enterprise.

The envelope is important for sustainable building. Recent commercial buildings are causing thermal degradation and cooling load due to the increase of the area of the windows. Therefore, this research studied kinetic shading system which can improve energy saving and visual environment in summer. For that, this study proposed new shading system and shape considering the orientation of the building and the location of the sun. Based on this, this study analyzed the effectiveness on energy reduction and improvement of visual environment by applying the kinetic shading system proposed in this study. As the results of this study, energy reduction rate was 35% in the east, 22.9% in the south, and 30.7% in the west depending on the application location. Also, as the result of the illuminance analysis, it was found that the effect of achieving uniformity ratio of illumination was considerable.

Objective: The objective of this study was to investigate the effect of the thoracic mobility exercise program on pain, proprioception, and static balance ability in patients with non-specific chronic low back pain. Design: Randomized controlled trial design. Methods: Thirty patients with non-specific chronic low back pain participated in this study. The participants were randomized into the thoracic mobility exercise group (n=15) and the lumbar stabilization exercise group (n=15). Both groups received traditional physical therapy for 30 minutes per session. In addition, the thoracic mobility exercise group and the lumbar stabilization exercise group each exercise 3 times a week for 6 weeks. All participants were measured visual analog scale, proprioception test, and static balance ability before and after the intervention. Results: After 6 weeks of interventions, the thoracic mobility exercise group showed greater improvement in visual analog scale, proprioception test, and static balance ability than the LSE group (p<0.05). Further, the thoracic mobility exercise group had significant Enhancements in all measured variables compared to the baselinetest (p<0.05). However, the lumbar stabilization exercise group had significant improvement only visual analog scale, and static balance ability compared to the baselinetest (p<0.05). Conclusions: Our investigation demonstrates that the thoracic mobility exercise is an effective intervention method for improving pain, proprioception, and static balance ability in patients with non-specific chronic low back pain.

Purpose: Autologous fat injection into the facial area is a frequently used technique in aesthetic plastic surgery for augmentation of the soft tissue. Fat injection is a very safe procedure because of the advantage of being autologous tissue. Minimal foreign body reaction or infections are noted after fat injection. However, there may be some complications including those as severe as blindness. There have been some case reports on visual disturbances after autologous fat injection reported in the literature. Methods: A 21-year-old female patient underwent autologous fat injection into left eyebrow area to correct depression of soft tissue. Immediately after injection of autologous fat, she complained sudden visual loss on the left eye. She had come to our emergency room and ophthalmologic evaluation showed that the patient could only recognize hand motion. There was no abnormality of the optic nerve on magnetic resonance imaging. Suspecting an ischemic optic neuritis from fat embolism of the central retinal artery, the patient was treated conservatively with occular massage, antiglaucomatic agent, anti-inflammatory drugs and antibiotics. Visual field examination showed visual defect of half the lower hemisphere. Results: While maintaining antiglaucomatic agents and non steroidal anti inflammatory drugs, fundoscopic examination showed no abnormalities on the second day of admission. Visual field examination showed an improvement on the fourth day along with decreased eyeball pain. Significant improvement of vision was noted and the patient was discharged on the fifth day of admission. The patient was followed-up 2 days afterwards with improved vision and visual field defect. Conclusion: We describe an unusual case of sudden unilateral visual disturbance following autologous fat injection into periorbital area.

시각 커뮤니케이션에서의 영상의 역할은 정보화의 진전에 따라 더욱 증대해 가고 있다. 물론 그것은 정보의 직접적, 구체적 재현이라는 기능에만 있는 것이 아니라 영상에 의한 이미지 표현의 무한한 가능성을 추구하는 것이다. 이것은 또한 앞으로의 영상 커뮤니케이션의 방향이기도하다. 그러므로 본 논문에서는 고도화된 현대사회에서 쏟아져 나오는 영상 이미지들을 커뮤니케이션 수단으로 본다면 시각정보의 이미지를 지각하는 사용자 정보처리에 대한 시각기호의 방법론의 의미작용 과정을 인지함으로써 수용자와의 상호작용에 있어 커뮤니케이션의 기능 향상을 훌륭히 수행해 나갈 수 있다는 관점으로 성립된다는 것이다.

This paper proposes an efficient photo retrieval system that automatically indexes for searching of relevant images, using a combination of geo-coded information, direction/location of image capture device and content-based visual features. A photo image is labeled with its GPS (Global Positioning System) coordinates and direction of the camera view at the moment of capture, and the label leads to generate a geo-spatial index with three core elements of latitude, longitude and viewing direction. Then, content-based visual features are extracted and combined with the geo-spatial information, for indexing and retrieving the photo images. For user's querying process, the proposed method adopts two steps as a progressive approach, filtering the relevant subset prior to use a content-based ranking function. To evaluate the performance of the proposed scheme, we assess the simulation performance in terms of average precision and F-score, using a natural photo collection. Comparing the proposed approach to retrieve using only visual features, an improvement of 20.8% was observed. The experimental results show that the proposed method exhibited a significant enhancement of around 7.2% in retrieval effectiveness, compared to previous work. These results reveal that a combination of context and content analysis is markedly more efficient and meaningful that using only visual feature for image search.

Men perceive and react around him through the five senses. Also men give rise to the human sensibility and maintain his emotion. This study doesn't limit working environment to VDT environment, but considers the universal working environment acquiring information by eyesight stimulation. In case of forming an abnormal veiling reflection we consider the form ; a vertical(25%, 50%, 75%)and a horizontal(25%, 50%, 75%). The results from the subjective evaluation are analyzed by SD(Semantic Differentical methodology)of 5 point scale for visibility and nuisance when an abnormal veiling reflection forms on target. In addition, the results of the objective evaluation are suggested by measuring and analyzing EEG of bio-signal for visual sensitivity. The results of this study can apply to basic data which create a guideline of a visual operation. In particular, it can be designed as an illumination environment concerning an ergonomic factor on visual operations, mental stress such as a visual inspection operation, visual information search operation, etc. As a result, we can expect to reduce the visual nuisance and contribute to the improvement of the performance and the uplift of the competitive power.

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.
