This study was conducted to investigate the status and the life satisfaction of amputees from July 9, 2001 to August 18, 2001. Questionnaire survey was collected from lower extremity amputees using the services of prosthetic and orthotic centers in five Veterans Hospitals (Seoul, Busan, Gwangju, Daeku, and Daejun), Seoul Tehlin prosthetic and orthotic center, Chunan prosthetic and orthotic center, and Junju Lee Ganga rehabilitation institute. Amputees were grouped as trans-tibial amputees, trans-femoral amputees, and bilateral amputees based on amputation level. Demographic and social characteristics, performance of social role, and factors influencing life satisfaction revealed findings as follows: 1) The number of subjects voluntarily participated in the study was 113 (109 men, 4 women), and the mean age of subjects was 53.65 years (age range=22-74 years). 2) The time of amputation was at their second decade mostly (72.6%), and the most common etiology of amputation was trauma (91.2%). 3) The most common type of amputation was trans-tibial amputation (59.3%). Subjects who were employed was 68.1% before amputation and 47.8% after amputation. Subject had income regardless of being employed or unemployed after amputation. 4) No significant difference was found between the scores of social role and the scores of life satisfaction in three groups(p<0.05). 5) The significant factors on life satisfaction was income status and occupational role among variables(p<0.05).

When root initiation ratio of cut Birdsfoot trefoil (Lotus corniculatus L.) stems was examined in several medium conditions containing different IBA concentration, the higher IBA contration of medium was elucidated superior then lower IBA concentration.

이탈리안 라이그라스 (Lolium multiflorum Lam.) 의 절단한 줄기를 살균처리한 다음, IBA론 첨가한 농도별로 5종의 배지에 처리별로 각각 20개씩 절단한 줄기를 꽃은 후, 4 암상태에서 40일간 보관하였다가. 실온에 하루동안 둔 다음, 26로 유지되는 생장실에서 배양하며 뿌리가 유도되는 정도를 관찰하였다. 생장실에서 배양한 지 1개월째에 뿌리유도 정도를 조사한 결과, MS-0 처리구에서 0.0%, MS-0.5IBA 처리구에서 8.3%,

알팔파 (Medicago sativa L.)의 줄기부분을 절단하여, SH 배지에 IBA를 첨가한 농도별로 뿌리 유도 정도를 조사한 결과, IBA 농도를 1.0~1.5 mg/로 첨가한 처리구에서 뿌리 유도 정도가 70~75%로서 가장 좋았다. 캘러스로부터 shoot를 유도한 다음 줄기를 취하여 처리한 경우에는. 처리 10일째에 1/2 SH-0 배지에서 10개 (50%), SH-0 배지에서 10 (50%), SH-0.5IBA 배지에서 12개 (60%), S

본 증례연구는 복합손상을 가진 척수손상환자의 재활치료과정을 소개하여 유사한 사례의 치료에 도움이 되고자 하는 것이다. 증례연구의 대상자인 26세의 남자환자는 흉수 4번 완전손상과 사고 당시 전기화상에 의한 좌측하박 절단과 우측손의 정중신경이 마비되었다. 치료초기에는 일상생활동작 검사에서 MBI (Modified Barthel Index) 점수가 22점으로 독립적으로 가능한 것은 거의 없었고, 기능적으로도 모든 도움이 필요한 상태였으나 재활치료결과 독립적

이식 전 수정란의 성판정은 많은 축산인의 소망이었다. 많은 방법이 제기되었지만, 세포유전학적 분석방법은 ET의 상용화에 거의 무의미할 정도로 한계가 많았고, 이후 개발된 응성 특이적 항원이나 X-염색체에서 발현되는 효소의 활동을 통한 성판정 방법은 흥미롭기는 하나 산업적 적용에 제약이 많았다. 80년대 중반 Y-염색체 특이적인 DNA 탐침자의 개발과 PCR을 통한 DNA증폭기술의 개발은 수정란 성판정을 획기적으로 개선시켰다. DNA기술을 통한 수정란의

임상 결과의 측정에서 새로운 관점을 갖는 것은 중요하다. 의료 재활은 심리적 측정의 질들(표준화, 신뢰도, 타당도)에서 충분한 노력에 수행되어지지 않아 왔기 때문에 환자와 프로그램 사이에 일반화된 기능적인 평가 범위가 부족하다. 장애의 적절한 측정을 위한 요구는 기능적인 상태에서 변화들을 알리고 치료의 필요성을 평가하고 치료를 계획하고 결과를 예측하고 보상 방법을 측정하기 위한 환자의 치료와 임상 연구에서 모두 나타난다. 세계적으로 사용되어지고 있는 기

As the first step of study on fabrication of ceramic powders from phytoliths in rice, especially in rice husks, pulverization method of rice husks and the properties of milled rice husks were investigated. Impact methods, such as ball milling, were not meaningful for pulverizing elastic and thin fabric structure of rice husks. The most effective one was cutting method. In the present work, a rotating knife cutting method was applied to pulverizing rice husks. A 40-mesh screen was inserted under the rotating knives. The most portion of the milled powder was found in -50/+100 mesh section. Morphology of the milled rice husks revealed that the husks larger than 70 mesh were flake-like shape, at -70/+100 mesh section relatively equi-axed shape, at -170/+325 mesh section rod-like shape, and below 325 mesh section dust-like shape. Tap density of raw rice husks was about 0.1 , while those of milled rice husks were over . This meant that, for a given volume of reactor, raw material charge can be increased more that 4 times when using milled rice husks than unmilled one. True densities of unmilled and milled rice husks were higher than , and increased with decreasing milled sizes.

The purpose of this case study was to introduce a myoelectric hand prosthesis for upper extremity amputee and prosthetic training program. Limb loss can result from disease, injury, or congenital causes. Trauma has been increasingly important role as the cause of amputaion in young, vigorous, and otherwise healthy individuals. The higher the level of amputation the greater the functional loss of the part, and the more the amputee must depend on the prostheis for fuction and cosmesis. Myoelectrical control of prostheses is a recent development and has been steadily gaining in clinical use over the past 20 years. Such a prosthesis uses signals from muscle contraction within the stump to activate a battery driven moter that operates specific component fuctions of the prosthesis. This twenty years old male case was operated a right above-elbow amputation due to tracffic accident and admitted to Yonsei Rehabilitaion hospital for the preprosthetic and prosthetic training. The case was able to successfully complete his myoelectric hand prosthesis training in the February of 1995.

Anopheles quadrimaculatus( Say) 자매종 간의 미토콘드리아 DNA의 제한효소 절단부위변이를 Aedes albopictus의 마토콘드리아 cDNA를 probe로 이용하여 조사하였다. DNA hybridization에 의해 두 속간에는 mtDNA 영기서열의 상당한 상동성이 있음을 알 수 있었다. 개체 모기로부터 분리한 DNA를 제한효소를 사용하여 절단한 결과 자매종간에 다른 양상을 볼 수 있었으며 Hind III에 의한 mtDNA 절편만으로도 자매종들을 동정할 수 있었다.
