In this paper, when receiving image input from various angles from an electronic medium such as a smartphone, a system for recognizing and translating characters by processing images in the image is presented. The translator designed in this paper processed images using a library called OpenCV. Through OpenCV, the boundary of the image can be found, and the distorted image is corrected. After that, Tesseract-OCR was used to enable the computer to convert the characters displayed in the image into strings. After transforming the image that was not placed forward as a function of OpneCV in the forward direction, Tesseract was applied to the deformed image. Characters in images from various angles were recognized, translated using Google Translation API, and the results were displayed on the image and presented.

This study was carried out for reorientation of Rehabilitation Service Delivery System (RSDS) through reviewing reference and observing field practice. The most important results are as follows: 1. The current rehabilitation facility for handicapped persons can be classified into four categories : (a) those for physically disabled persons, (b) those for mentally disturbed persons, (c) those for visually disturbed persons, and (d) those for acoustic and speech disturbed persons. The nationwide number of rehabilitation facilities is 101 of those, 43.5% is for physically disabled persons and 32.9% is for mentally disturbed persons. 2. A small number of circulating rehabilitation centers for physically disability are being run by comprehensive rehabilitation centers since 1992. 3. The hospitals are self-supporting only 20% of their operational costs, and the rest of the operational costs comes from federal tax(40%) and local tax(40%). 4. The number of handicapped persons in Taegu and Kyungpook province is estimated to be about 50,000, but only 20 percent out of them ws registered. The rehabilitation facilities located in this area receives 69% of their operational costs from central government. This figure is higher than the national average of 64.6%. 5. Although RSDS is different from other medical delivery system, nonetheless, it should be developed as a sub-system of national health care delivery system. Its development should also be in accordance with the need of local community. Therefore we suggest the development policy for the development of RMDS must consider the following points.; First, all rehabilitation-related medical systems should be integrated unde ra single comprehensive system so that handicapped persons may easily obtain better service available. Second, rehabilitation programs based on local community should be rejuvenated. In addition to in-patient service, development of intermediate facilities and programs connecting home and society should be encouraged. Third, rehabilitation medical services should be more specialized. Also, more emphasis should be given to team approach to rehabilitation medical services. Fourth, a comprehensive rehabilitation information system should be developed so that handicapped persons may have easy access to public welfare facilities, and the central government should formulate a comprehensive long-term plan for the rehabilitation system.

Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.

이 연구는 뇌졸중으로 인한 편마비 환자에게 보행훈련방법을 달리하였을 때, 일반적인 지면과 트레드밀, 불안정면을 이용한 보행훈련이 보행요소와 족저압에 미치는 영향을 알아보기 위하여 편마비 환자 30명을 지면과 트레드밀, 불안정면 보행훈련군으로 무작위 배정하고 각 치료군들은 주 5회, 8주 간의 보행훈련을 실시하였다. 실험 전과 후, 보행요소를 알아보기 위하여 보행속도, 보장, 보각과 족저압을 측정하여 수집된 자료를 분석하여 다음과 같은 결과를 얻었다. 이 연구의 결과를 종합해 보면 보행훈련방법에 따라 지면 보행훈련은 보행속도와 족저압 전족부, 트레드밀 보행훈련군은 보행속도와 보각, 족저압 중족부, 불안정면 보행훈련군은 보행속도와 보장, 보각에서 유의한 증가를 보였다. 이러한 결과는 뇌졸중으로 인한 편마비 환자에게 보행훈련방법을 달리함에 따라 많은 영향을 끼치어, 환경의 변화와 다양한 과제에 대한 적절한 반응을 만들어 낼 수 있음을 의미하며, 기능 회복의 임상적 접근에서 치료 중재의 시점과 기간, 제공되는 환경, 과제의 선택에 대한 광범위한 연구가 필요할 것으로 생각되어진다. Purpose : This study was performed for effects of gait component and plantar foot pressure on gait training way needed in gait with hemiplegic patients caused by cerebrovascular accident. Methods : Three groups of adult hemiplegia(n=30) were allocated randomly in this study : group I(TGT : treadmill gait training), group II(USGT : unstable surface gait training) and group III(SGT : surface gait training). The gait training was provided to experimental groups for 8 weeks(5 times a week). Measurements of pre and post experiment were gait velocity, step length, toe out angle, foot plantar pressure which demonstrate temporal-spatial parameter of gait component. Results : The results of this study showed that in comparison of pre and post changes of gait training, SGT group has statistically significant differences in gait velocity, metatarsal area of foot plantar pressure, TGT group has statistically significant differences in gait velocity, toe out angle, midfoot of foot plantar pressure. USGT group has statistically significant differences in gait velocity, step length, toe out angle. Conclusion : These results mean gait training resulted by gait training way provides effective gait, with stroke, and therefore proper response about environmental changes and various tasks could be made.

APF Gel이 심미 수복재료의 표면에 미치는 영향

최원혁,김은정,김현정,김영진,남순현 大韓小兒齒科學會 2006 大韓小兒齒科學會誌 Vol.33 No.2

현재 소아치과 영역에서 소아의 치아 우식증을 예방하기 위해 다양한 불소 도포법이 시행되고 있다. 이들은 법랑질 내 불소함량을 증가시키고 보다 안정된 결정 구조를 형성하게 하여 치아 우식증을 예방한다는데 근거하고 있다. 하지만 최근에 불소 도포제재가 심미 수복재료의 표면에 부작용을 일으킬 수 있다는 문제가 제기되고 있다. 이에 본 연구는 수종의 심미 수복재료의 표면에 APF gel이 미칠 수 있는 영향을 주사 전자 현미경을 통해 관찰하고 표면 조도를 측정한 후 비교 분석하여 다음과 같은 결과를 얻었다. 1. glass ionomer cement와 compomer를 이용한 실험에서 APF gel 4분 침적군과 pH 순환군은 인공타액 침적군에 비해 표면 조도가 증가하였다(p<0.01). 2. composite resin 인 Charisma와 Z250을 이용한 실험에서는 모든 군간의 표면 조도의 차이는 없었다(p>0.05). 3. 주사 전자 현미경으로 관찰한 결과 glass ionomer cement, compomer, composite resin의 순으로 filler의 소실이 많았으며 군별로는 pH 순환군, APF gel 4분 침적군, 인공타액 침적군의 순으로 filler의 소실이 많았다. Topical fluoride application for children is a widely performed procedure in the field of Pediatric Dentistry for its dental caries prevention effects. However, it is recently recognized as having some unwanted effects on several esthetic restorative materials, the author immersed glass ionomer cement, compomer and composite resin specimens in APF gel and measured the surface roughness and also, examined the specimens under the scanning eletron microscope. The followings are the results: 1. In the specimens of glass ionomer cement and compomer, APF gel 4 minute immersion group and pH cycling group show statistically significant increased surface roughness than artificial saliva immersion group(p<0.01). 2. There was no statistically significant surface roughness for composite resin in all group(p>0.05). 3. When the specimens were examined under scanning electron microscope, the surface change were in the order of glass ionomer cement, compomer, composite resin and also in the order of pH cycling group, APF gel 4 minutes immersion group, artificial saliva immersion group.

상악 정중이개 치료시 rubber band의 부적절한 사용 : A CASE REPORT

최원혁,김은정,김현정,김영진,남순현 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.3

정중이개란 상악 중절치 사이의 치간이개를 말한다. 이는 혼합 치열기에서 ugly ducking stage에 흔히 관찰할 수 있으며 일반적으로 견치가 맹출하면서 자연적으로 소실되므로 꼭 치료가 필요한 것은 아니다. 그러나 견치 맹출 후에도 정중이개가 2mm이하로 계속 존재하거나 견치 맹출 전이라도 3mm이상의 정중이개가 존재하는 경우에서는 치료의 적응증이 될 수 있다. 특히 후자의 경우 심미적인 면에서 뿐만 아니라, 이로 인해 측절치와 견치의 맹출공간이 부족해지는 문제가 발생하므로 교정치료가 권장된다. 정중이개 치료시 사용되는 장치물은 finger spring 등을 이용한 가철성 장치물과, 교정용 band, tube, bracket 등을 부착시켜 rubber elastics이나 coil spring 등을 사용하는 고정성 장치물로 나뉘어진다. 그러나 정중이개의 치료를 위해 rubber band를 band, tube, bracket 등과 같은 적절한 부가장치 없이 사용하면 rubber band가 치근은 따라 치은 하방으로 이동하게 되고 치주 인대를 파괴하며 치근단 부위에 이르러 치아동요, 치아정출 및 탈락 등 치아에 치명적인 손상을 입힐 수 있다. 본 증례는 정중이개의 치료를 위해 부적절하게 rubber band를 사용하여 외상을 받은 치아를 관찰하여 다소의 지견을 얻었기에 이를 보고하는 바이다. Maxillary median diastema is the term used when there is spacing between maxillary central incisors. The space between maxillary central incisors are often observed during ugly duckling stage. In most of the cases, as maxillary permanent canines erupt, it gradually disappears. Maxillary median diastema needs to be treated when there is up to 2mm of space between the incisors even after eruption of permanent canines or when there is 3mm of space, at least, before the eruption of the canines. Particulary, for the latter case, orthodontic treatment is recommended because not only the esthetic point of view but also to regain the eruption space for maxillary lateral incisors and canines. The appliance used for orthodontic treatment are removable appliances, using finger spring and etc, and fixed appliances, using rubber elastics and coil spring. If rubber band alone was used to treat median diastema without any other appliance such as band, tube or bracket, it will gradually move downward along the root surface. Then it will destroy the peridontal ligament and causes tooth mobility, extrusion, and avulsion. This report presents cases of damaged tooth due to improper use of rubber band when treating maxillary median diastema.
