Recent experimental studies and clinical cases have suggested that grafting tissue from the adrenal medulla into the brain may alleviate the symptoms of Parkinson's disease. Autologous adrenal medullary grafts into the striatum was performed stereotactically in two patients with Parkinson's disease. Both patients were bedridden preoperatively, but 4 months after the surgery both became ambulatory and one was even capable of returning to his job. Even though the number of cases was small⑵ and the follow-up period was short, this study shows that adrenal medullary transplantation into the striatum may have some beneficial effects in patient with Parkinson's disease. Further experimental and clinical trials are necessary to see whether this procedure will be a recommendable surgical treatment for patients suffering from Parkinson's disease.

VDT작업자에서 어깨 근육장애와 혈청 CPK의 관련성

정해관,김수근 大韓産業醫學會 1998 대한직업환경의학회지 Vol.10 No.2

VDT workers are often exposed to static load in the shoulder stabilizing muscle due to repetitive work over long periods. Many investigations were reported the relationships between static load due to repetitive work and regional muscle disorder. However, diagnostic approach to work-related muscle disorder is difficult due to the absence of objective dignostic tools. This study was performed to investigate the relationship between the serum CPK(creatine phosphokinase) concentrations and the shoulder muscle disorders. Results are as follow. 1. Mean serum CPK in total VDT workers was 67.6±28.4 IU/l and workers with abnormal serum CPK were 35(21.5%). 2. Comparison between cases and controls did not show significant difference in the serum CPK level and the distribution of abnormal findings. 3. Sensitivity and sepcificity of the CPK test was 23.0% and 82.0%, respectively. Above results, in accordance with literatures, show that while serum CPK measurement can be useful for the diagnosis of acute muscle injury, it does not adequately reflect the muscle disorders developed by the repetitive work of low tension over long time, such as VDT works.

In the general, the speed control of single-phase induction motor is accomplished at a few discrete speed by using tapped-winding, pole changing or gear. These technique is inefficient and complicated. In the reason, the applied voltage of single-phase induction motor is controlled for improvement speed characteristics. The AC converter can be easily realized using module transistor. The output voltage from the AC converter is applied to single-phase induction motor. This paper presented operating characteristics of single-phase induction motor by AC converter.

蔡洙天,鄭龍文 公州大學校 資源科學硏究所 1998 資源科學硏究論文集 Vol.6 No.-

In order to restore the vegetation that was demolished by imported goats in Ogasawara Islands, the damaged States in Mukogima, Nakoudogima, Yomegima and Nishigima island that were badly damaged among Ogasawara Islands were investigated, and the removal method of goats, the counterplan for restoration of vegetation and restoration technique for vegetation were inquired. The results obtained are as follows; 1. The temperature and amount of pricipitation of the yearly mean in Ogasawara were 23℃ and 1229.1mm respectively, and this Islands were belonged to the oceanic subtropical zone. 2. The main vegetation in four island were Pisonia umbellifera,Callicarpa subpubescens, Ochrosia nakaiana, Livistonia chinensis, Drypetes integerrima, Pandanus boninensis, Terenna subsessilis, Sporobolus diander, Oplismenus compositus, Gramineae spp. etc. 3. The vegetation and top soil in four islands were extinct by eating and over-walks of goats and severely washed out by rainfall and wind. 4. The number of goats were increased yearly, and were 766 in Mukogima, 189 in Nakoudogoma, 92 in Yomegima and 41 in Nishigima in 1997, respectively. 5. To control goats and to restore the vegetation, the fence was set up in the place was badly damaged by goats. 6. Within the fence to control goats, sand bag method to soil erosion, small dam, vegetation mat method and seed spray method were treated with.

PAR 지수를 이용한 교정치료 결과의 평가에 관한 연구

정수봉,박영국 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.4

교정치료의 결과를 평가하는 방법에는 두부방사선계측이나 석고모형을 이용하는 방법등이 있다. 교합지수는 석고모형을 이용한 평가방법 중 하나로, 교합 상태를 하나의 수치로 표현하기 때문에 정량적으로 평가할 수 있고 계측이 객관적이며 교정치료의 결과를 평가하는데 있어서 표준화가 가능하다는 장점이 있다. 이 연구는 PAR지수를 이용하여 경희대학교 치과대학 교정과에서 시행되는 교정치료의 결과를 평가하고, 교정치료 증례들의 교정치료 전과 추적 관찰기의 교합 변화를 평가하며, 교정치료 전후의 결과가 치료 전 증례의 Angle 분류와 상관성이 있는지를 평가하기 위해 시행되었다. 영구치열기에 교정치료를 시작하여 고정식 교정장치로 치료하였고, 교정장치를 제거한 후 최소 24개월이 경과한 I급 부정교합 9 증례, II급 1류 부정교합 8 증례, III급 부정교합 8 증례 등 총 25 증례의 교정치료 전, 교정치료 종료 시, 추적 관찰기의 석고모형을 대상으로 PAR (Peer Assessment Rating) 지수를 이용한 교정치료의 결과 및 재발에 관한 연구를 시행하여 다음의 결론을 얻었다. 1.교정치료 종료 시 평균 85.05%의 가중된 PAR 점수의 개선을 보였으며, 이는 'high standard of treatment'에 해당된다. 2.추적 관찰기에는 교정치료 전과 비교하여 평균 75.40%의 가중된 PAR점수 개선을 보였으며, 교정치료 종료 시와 비교하여 추적 관찰 기간동안 9.65%의 가중된 PAR 점수의 증가가 있었다. 3.교정치료 전 Angle 분류와 치료 전후의 PAR 지수 변화량 간에는 상관관계가 없었다. (주요 단어 : PAR 지수, 재발, 안정성) The purposes of this study were to assess the treatment results in orthodontic department, Kyung Hee University, to evaluate the occlusion at 2 year follow-up control, in relation to the original malocclusion, and changes occurring in the follow-up period, and to determine whether treatment and posttreatment changes of the PAR index were related to the original Angle classification Dental study casts of 25 patients in permanent dentition were evaluated using Peer Assessment Rating (PAR) index. The PAR index was measured at the pretreatment stage, immediately after treatment, and at 2 years posttreatment. The following results were obtained : 1.The treatment reduced the PAR index by 85.05% and it indicates that KHDC clinic has a high standard of treatment 2.The follow-up result of 75.40% PAR score reduction implies a gain of 9.65% of posttreatment PAR score during follow-up period. 3.There is no relationship between the treatment changes of the PAR index and the original Angle classification. ※ Key words : PAR index, Relapse, Stability

This study was to examine the central foundation stone of wooden pagodas in Kyongju. In order to enshrine the Sarrira of Buddha, it was used for the building the pilla at the floor of wooden pagodas in Shilla period. Therefore, the style of the major pilla was built at the floor of the wooden pagodas, this style has been changed by a central foundation stone. The wooden- frame assembled style of multi- story pagodas had been changed by the central foundation stone. As a result, it was found that the style of wooden pagodas has been changed tranditionally in Shilla period.

조용수,조정환 진주여자전문대학 1995 論文集 Vol.18 No.-

The most important thing of the corporate color can be a visual effect. In recent, recognizing the importance of corporate identity, many companies are introducing a new CI contending with others. Accordingly the consumers select the importance of color first in recognizing the image of corporate. The purpose of this study is to describe the relations of corporate color and form affecting in case of selecting corporate color, the meaning of colors, the colors being affected in fashion, the corporate color of two tones, special color and the regional differences of colors. So it is to represent a good direction in case of selecting corporate color in many companies. This study will also suggest the direction of analytical method of corporate color applying image scale of NCD, and will predict and analyze the following tendency of corporate color.

진동공구 사용에 의한 Hand Arm Vibration Syndrome 1례

김수근,정해관,황정수 東國大學校醫學硏究所 2002 東國醫學 Vol.9 No.1

수완진동증후군은 진동공구를 사용하는 작업자에게 발생한다. 이 질병은 레이노 현상이 직업성 원인으로 오는 경우로 1950년대에는 진동증후군 또는 vibration induced white finger(VWF)로 알려졌고, 1983년 영국 런던국제회의에서 국소진동에 의한 건강장해에 대항 병명을 통일하여 "수완진동증후군(hand-arm vibration syndrome)"이라고 정하였다. 이것은 한랭노출시 수지색깔이 희게 변하고 손과 팔에 통증이 나타나며, 골관절염이 발생하게 된다.자동차 정비 작업장에서 11년간 임팩터 등 진동공구를 사용한 근로자가 한랭노출시 수지 색깔 변화와 저린감 등을 호소하여 이에 대한 의학적 면담과 객관적 소견을 얻기 위한 한랭유발반응검사, 진동감각역치 검사와 상지혈관조영술 및 감별진단을 위한 항핵항체와 한랭면역글로블린 검사를 실시하여 수완진동증후군으로 진단하였다. A hand-arm vibration syndrome occurs in some workers who use hand held vibration tools. It is known by Raynaud's phenomenon of occupational origin in 1950s as 'the vibration syndrome' or vibration induced white finger' has, in the 1980s, been renamed 'the hand arm vibration syndrome'. It consist of white fingers, pain in the hand and arm, and a small excess risk of osteoarthritis. We report a case of hand arm vibration syndrome in worker exposed to hand arm vibration diagnosed objectively by skin emperature, vibration sens changes and upper extremity angiogrphy.
