This paper descirbes a Braille training system that helps to learn braille effectively. The system converts written text to voice and exerts braille tactile pins simultaneously according to the text. The system consists of a voice sysnthesis device for converting text to voice, tactile device, and software to control the devices. The tactile device includes a control unit, pin array, pin action generator, serial port, and a power supply, and the tactile pins are exerted by solenoid. The Braille training system has been used to teach braille to people who do not know braille at all. It is found that the group of people who learned braille with the system showed much better braille recognition capability compared to the group who learned braille by traditional method. Therefore, the Braille training system can be effective in learning braille.

A five year old female Yorkshire terrier dog with a history of hindlimb lameness was referred to the Veterinary Teaching Hospital of Chungnam National University. The patient had been treated surgically two times for patellar luxation in other animal hospital. On physical examination, hindlimb lameness, pain on left hindlimb and Lt/Rt medial patellar luxation (Grade Ⅲ) were observed. On the results of hindlimb radiographs, bilaterally medially luxated patella and degenerative joint disease (DJD) sign at both stifle joints were observed. According to physical examination and radiographs, it was diagnosed as bilateral medial patellar luxation (Grade Ⅲ). The left hindlimb of patient was surgically treated with trochlear wedge resection (TWR), tibial tuberosity transposition (TTT), patellar and tibial antirotational suture and lateral retinacular overlap. After the surgical treatment, the patient was slowly recovered.

This study is performed to odor predictions at paper manufactory, to provide guideline for design and evaluation of facility construction and operations. Odor and VOCs materials were measured at five points as incinerator, DIP and TMP. The results show that odors are observed in Hydrogen Sulfide, Mercaptan, stylene and VOCs are detected in alkane, terpene. Especially, pinenes among terpenes are detected a lot because of character of paper manufactory. In order to analysis quality and quantity of VOCs at stack, the operation temperature of milling dryers outlet was changed to 100℃ and 120℃. The results show that discharge of alkanes and concentration of VOCs measured at the 4 part decreases significantly but terpenes is quite abundant in operation at 100℃ than 12 0℃.

정부는 벤처기업육성을 위해 '과학기술진흥법' 및 '산업기술기반조성에 관한 법률'을 정비하여 기술담보제도의 활성화룰 시도하고 있다. 또한 특허나 공공기술의 민간 이전 및 사업화가 부족하다는 평가 속에서 새로운 기술거래시장의 필요성이 제기되고 있고, 2000년 1월 '기술이전촉진법'의 공포로 '한국기술거래소'가 설립되었다. 이러한 기술담보제도 및 기술거래제도는 공정하고 신뢰성 있는 기술가치평가기관을 필수로 한다. 현재 기술가치의 평가 및 결과에 대한 신뢰성이 미확보된 상태에서는 기술가치평가와 관련한 새로운 연구 및 전문적인 평가기관이 필요하다. 아울러 기술가치평가업무 자체가 전문적이면서도 기업의 비밀보호 등 엄격한 규율을 필요로 하므로 안정적인 기술가치평가전문인의 양성과 관리가 필요하다. 한국에서 기술을 평가하는 방법으로는 기존에 과학기술부와 공공연구소를 중심으로 가장 많이 시행되고 있는 기술성(기술력) 분석으로, 보다 구체적으로는 기술의 동향, 기술수준 및 등급을 분석하고 기술개발의 목표 및 전략성을 분석하며 기술적 성과, 파급효과 등을 분석하는 방법이 있다. 둘째로는 환경문제와 같은 기술의 사회, 환경적 분석(assessment)을 위주로 하여 기술의 사회적 영향, 즉 이익 및 피해를 분석하는 방법으로서, 주로 기술의 국방·안보적 요인, 및 상업, 정치, 문화적 기여도 등을 평가하는 방법이 있다. 셋째로는 기술의 경제성 및 사업성 분석으로 Cost benefit을 위주로 현장중심의 경제성 분석(feasibility study)과 경제적인 파급효과(economic effect) 및 기여도를 분석한다. 넷째로는 회계사나 재무분석가 등을 통해 사용되는 협의의 기술가치평가(technology valuation)로, 이 방법은 기술의 사회적인 요인은 무시하고 돈으로 환산되는 화폐적 가치만을 측정한다. 그러나 현재의 추세는 기존의 방법론에 의한 기술의 평가도 돈으로 표시하려는 경향이 나타나고 있으며, 또한 기술의 전체적이고 종합적인 가치에 대한 신뢰성 있는 평가의 필요성이 점증하고 있다. 본 연구는 기업의 기술경쟁력 평가를 통하여 평가결과에 기초한 기술이전, 기술거래 확산을 위한 정책적 활용방안 및 기술개발 촉진체제 구축방안을 제시하는데 있다.

Background: Many chronic diseases are associated with the lifestyle such as smoking, alcohol drinking and exercise. Attention is increasingly paid on the effect of exercise for the management of chronic disease these days. Objective: The purpose of this study was to evaluate the status of the smoking habit, alcohol drinking and physical exercise of the patients with chronic diseases. Methods: Total 793 persons(normal:422, chronic disease patients:371) in a hospital were questioned regarding the habits of smoking and alcohol drinking, and a practice of physical exercise in 1999. The patients with chronic illness were divided into three groups(Group I included the patients of hypertension and diabetes mellitus. Group II includes respiratory disease and cancer. Group III included liver disease ). The rate of exercise, the rate of smoking cessation and the rate of abstinence were assessed. In logistic regression analysis with each independent variables in each disease groups(I, II and III), odds ratio for the presence of disease was controlled for age and education. Results: The rate of exercise, the rate of smoking cessation and the rate of abstinence was 31.5%, 27.3% and 9.5% in the patients with chronic disease, respectively. In control group, those were 31.5%, 21% and 2.1%, respectively. In logistic regression analysis with exercise as independent variable, odds ratios(95% CI) for age and education were significantly high, with smoking cessation, odds ratio for age was high and with abstinence, odds ratio for disease was high in all disease groups. Conclusion : It was suggested that an effort for proper changes of lifestyle related to disease such as smoking, alcohol drinking and exercise should be intervened in the patients with chronic diseases.

Background: The purpose of this study was to determine the effectiveness of percutaneously place self-expanding metallic stent for the relief of biliary obstruction in patients with hilar cholangiocarcinoma. Materials and Methods: From November 2001 to December 2004, 48 patients with hilar cholangiocarcinoma were prospectively studied. After percutaneous placement of bilateral self-expanding, uncovered metallic stents, follow-up evaluation was carried out until July 2005. Results: There were 4 cased of Bismuth type Ⅱ,21 cases of Bismuth typeⅢa 8 cases of Bismuth type Ⅲb and 15 cases of Bismuth type Ⅳ. Stent placement was technically successful in all patients All patients had satisfactory biliary drainage, resulting in one week drainage rate of 72.8% and final drainage of 91.9% There were 12 cases (21.3%) of abdominal pain requiring analgesics and 1 case (7.1%) of cholangitis; both were successfully managed with conservative treatments. Late complications occurred in four patient (8.3%), including two patients with cholangitis, one patient with liver abscess, and one patient with biloma; all were appropriately managed by percutaneous drainage. The average length and median durations of stent patency and median survival time were 303 days (range, 60~815) and 338 days (range, 60 ~1175), respectively. Conclusion: Placement of a percutaneous metallic stent is an effective and safe method of palliation of patients with hilar cholangiocarcinoma.
