민병구,박찬영,최재순,이혁수,황창모,김삼성,윤걸중,김종원,선경,이경갑,정종태,김원곤 제주대학교 인공심장이식연구소 2001 인공심장 연구 Vol.2 No.1

현재 개발되고 있는 맥동형 이식형 인공심장은 완전이식형 인공심장과 좌심실보조장치 뿐이다. 좌심실보조장치를 장착한 환자의 10~15%가 우심실의 보조를 필요로하고 완전이식형 인공심장의 장착을 위해서는 자연심장을 제거해야하는 상황에서 이식형 양심실보조장치에 대한 필요성이 대두되고 있다. 본 연구진은 완전이식형 인공심장으로 개발된 한국형 인공심장을 개선하여 양심 실 보조장치를 개발하였다. 양심실보조장치는 이동형 작동기식 미케니즘을 이용하고 있으며 에너지 변환장치와 감속기로 구성된 작동기와 혈액주머니, 그리고 내장형 제어기로 구성되어 있다. 선인장 펌프로 명명된 KAH350은 캐뉼라의 연결을 위한 커넥터를 포함하여 길이 177mm, 폭 164mm, 높이 67 이고 무게 780g이며 최대 심박출량은 5L/min 이다. 양심실보조장치로 개발된 선인장펌프는 좌심실보조장치로도 응용이 가능하다. 이식적합성과 생체적합성을 평가하기 위하여 좌심실보조장치로 5회, 양싱실보조장치로 6회의 동물실험을 수행하였다. 각각 최장 28일간 생존하였으며 11회의 동물실험중 장치의 결함에 의한 것이 3회 있었는데 이들은 모두 전자장치의 결함과 방수처리문제였다. 현재 이식적합성과 일박출량을 향상시킨 KAH400모델이 개발중이다. The types of pulsatile implantable artificial hearts that are on the way of development and have been developed are totally implantable artificial heart and implantable left ventricular assist device (LVAD). Approximately 10% to 15% of all patients Implanted with wearable VADs have required right heart support with another device. And it is reluctant to patient who should remove his or her own heart to be implanted with total artificial heart. These situations drive the development of implantable bi-ventricular assist device (BVAD). The Korean BVAD was develophed by modifying the moving actuator type Korean artificial heart. This electro-mechanical BVAD comprises actuator including energy converter and reduction gear train, blood sacs, and internal motor and energy controllers. The KAH350 which is named as 'Cactus Pump' is 177mm in length, 164mm in width, and 67mm in thickness including connectors and nuts. The weight and maximum cardiac output of Cactus Pump is 780g and 5L/min, respectively. The Cactus Pump that was developed as BVAD could be used as LVAD by attaching compliance caps on the 2 ports of one ventricle. The animal experiments were undergone 5 times for LVAD, and 6 times for BVAD. The best records were 28 days survival in both applications. There were 3 times of device failure and they were all associated with electrical connection and hermetic sealing. The KAH400 that has improved anatomical fitting characterisitcs and stroke volume is on development.

원경준,이준,변유미,조민근,한경택,김원,홍란,임성철,김경종,김영대,박찬국,김만우 朝鮮大學校 附設 醫學硏究所 2007 The Medical Journal of Chosun University Vol.32 No.2

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

김민우,변승진,이경은,정소영,조주영,최원자,최찬양,김경 대구대학교 특수교육재활과학연구소 2011 再活科學硏究 Vol.29 No.1

이 연구는 컴퓨터 작업시 의자 등받이 위치가 근육활성도에 미치는 영향을 알아보기 위해 36명의 근골격에 문제가 없는 성인 남녀가 참가하였으며 대상자들은 등받이가 뒤에 있는 의자와 등받이가 없는 의자, 등받이가 앞에 있는 우리들 의자를 무작위로 배정하고 동일한 컴퓨터 작업을 실시하게 하였다. 실험 중, 표면근전도기를 사용하여 의자에 따른 위등세모근, 머리널판근 그리고 척주세움근의 근활성도 변화를 측정하였다. 이 연구의 결과를 종합해보면 등받이가 앞에 있는 의자는 허리 근육의 부담을 줄이지만 목근육에 부담이 늘어나고 등받이가 뒤에 있는 의자와 없는 의자는 허리근육에는 다소 무리가 가지만 목근육에는 부담이 덜하다는 것을 알 수 있었다. 이러한 결과로 환자의 증상에 다라 컴퓨터 작업을 하는 동안 의자 등받이의 위치를 조절하여 치료에 도움이 될 수 있다고 생각되어진다. Objective : In this study, we checked and observed people's change of body muscle and muscle activity who do computer work on different chairs. We set three kind of chairs which one is a stool and another one is the back is fixed, and the other one is the back is fixed in front of chair. Subject : Accounting for 36 health men and women, we divided these people to 3 groups and put them on the three cases(position 1, position 2, position 3). We measured muscle activity of upper trapezius, Splenius Cervics, Erector Spinae from the groups by using surface electromyogram system. Methods : The standard of the electromyogram was 'reference voluntary contraction', and we carried out 'one way anova' to compare muscle activity of three groups. Results : In position 1, reference voluntary contraction of upper trapezius muscle activity was 123.2821%, Splenius Cervics was 141.7526%, and Erector Spinae was 254.5233%. In position 2, reference voluntary contraction of upper trapezius muscle activity was 132.9395%, Splenius Cervics was 141.7526%, and Erector Spinae was 246.6540%. In position 3, reference voluntary contraction of upper trapezius muscle activity was 190.6487%, Splenius Cervics was 270.2332%, and Erector Spinae was 182.1021%. Both upper trapezius and Splenius Cervics muscle activity of position 3 group was higher than the others groups. In position 1 group, Erector Spinae muscle activity was hight than the other groups. And either was position 2 group's(p<0.05). Conclusion : Therefore the chair which is the back is fixed in front is more comfortable for waist muscle but it's not good for neck. And the other chairs are better in waist muscle but not in neck muscle. So far, when we do a computer work, it's prefer to sit on the group 1&2's chairs to reduce neck muscle's stress and sit on group 3's chair to reduce waist muscle's stress.

통합교육의 새로운 패러다임으로서의 유니버셜 디자인 철학의 고찰

김경민,송찬원 국립특수교육원 2005 특수교육연구 Vol.12 No.2

우리나라의 통합교육은 약 30여 년이라는 짧지 않은 역사를 가지고 있다. 그동안 많은 연구들이 통합교육의 당위성과 가치를 주장하고 실현 가능성을 증명했으며 통합교육의 실제를 긍정적으로 검토하며 특수교육이 나아가야 할 방향임을 강조하고 있는 것이 사실이다. 그러나 통합교육은 아직까지 이론과 실제 사이에 좁히지 못하는 차이를 가지고 있다. 따라서 본 연구에서는 “모든 사람들을 위한 디자인”이라는 철학을 지니고 있는 유니버셜 디자인의 철학을 바탕으로 개인의 다양성을 존중하고 차이를 수용하는 통합교육의 인간주의 패러다임의 한계를 제시하고, 유니버셜 디자인 철학에 의한 통합교육의 실현 가능성을 확인하는데 중점을 두었다. The inclusion in korea has a considerable history about 30 years. Many researches has insisted propriety and worthy and has proved the possibility of realization. Also examined the practice of inclusion in a positive view and emphasized the direction of special education. The inclusion in korea has a considerable history about 30 years. However the inclusion has still some problem not to narrow down the difference between theory and practice. In this study, universal design based on th philosophy, "the design for all" come to interpret humanism paradigm of inclusion which can respect the diversity of individuals and accept the difference of it, and put emphasis on possibility of realization for the inclusion. It has some significant meaning that paradigm of humanism took an inclusion to disability students who took separate-education by lay and socially. However, the limitation of barrier-free which emphasis on the circumstance of students with disability didn't solve the disadvantage of students without disability who take inclusion. As the result of it, inclusion has caused trouble between equality and superiority. To solve the limitation of it, the universal design's philosophy risen in architecture expanded to the aspect of education and became a universal design for learning(UDL). In conclusion, the converting of consciousness, that students without disability including the students with disability can access to study and receive an equal education, will show the possibility of realization for the detail inclusion and will be a new paradigm in making contribution to full inclusion.

除草劑 Paraquat가 미생물의 증식에 미치는 영향

金美林,朴燦性,崔慶浩 효성여자대학교 새마을연구소 1990 새마을硏究論文集 Vol.10 No.-

Experiments were carried out to understand the inhibitory effect of chemicals, especially that of a herbicide paraquat(1,1'-dimethyl-4,4'-bipy-lidilium dichloride) against microbial growth. Bacillus megaterium (ATCC 1787) was used as the indicator microorganism in the experiment. Among the eighteens of tested chemicals(insecticides 7, germicide 7 and 4 herbicides), six kinds of germicide and paraquat revealed an aparent repression against growth of the indicator organism at the concentrations pf ten ppm. Paraquat at the concentration above 1 x 10^-3M drastically repressed not only the growth of bacterial cells but yeast cells. Re-growth of the bacterial cell was inhibited in the concomitant presence of 1 x 10^-3M paraquat within eight hours of continuous cultivation, however, it was possible when con-centration of the herbicide was lowered 1 x 10^-4M.

박경찬,김정애,방형돈,조광현,윤재일,김병수 대한감염학회 1995 감염 Vol.27 No.3

배경 및 목적:조갑진균증의 치료에 있어 국소용 항진균제는 조갑판을 통과하지 못하기 때문에 치료율이 낮은 것으로 알려졌으나 최근 조갑판을 통과하여 조상에서도 높은 치료농도를 유지할 수 있는 국소용 항진균제인 ciclopirox nail lacquer가 개발되었다. 이에 본 저자들은 8% ciclopirox nail lacquer 단독 도포의 조갑진균증에서의 치료 효과와 안전성을 알아 보기 위한 연구를 수행하였다. 방법:표적 조갑판의 감염된 면적의 비율이 50%이하인 경증의 조갑진균증 환자 27명을 평가 대상으로 하였으며 8% ciclopirox nail lacquer 1일 1회 도포요법으로 6개월간 치료하였다. 매 방문시마다 감염면적 비율을 기록하였고 치료 전과 치료 후 진균 검사를 시행하였다. 결과: 1)표적조갑판의 감염 면적이 치료 전 평균 28.9%에서 치료 종료시 4.7%로 통계적으로 유의하게 감소하였다(p<0.001). 2)KOH 직접 도말 검사와 진균 배양 검사에서 모두 음성인 진균학적 완치율은 치료 종료시 77.8%였다. 3)부작용으로는 3명(11.1%)에서 일시적 작열감, 조갑 감입 등을 호소하였다. 결론:경증의 조갑진균증 치료에 있어 8% ciclopirox nail lacquer는 비교적 좋은 치료 효과를 보이며 부작용이 적은 약제로 생각된다. Background: Topical antifungal agents have been ineffective in the treatment of onychomycosis because they could not reach the infected nail bed. 8% ciclopirox nail lacquer is a new topical antimycotic which is characterized by excellent penetration into the nail plate. We performed a study to assess the therapeutic efficacy and safety of 8% ciclopirox nail lacquer in the treatment of onychomycosis. Methods: We assessed 27 onychomycotic patients whose affected area of target nail plate was not more than 50%. The patients were instructed to apply 8% ciclopirox nail lacquer once daily and evaluated monthly for 6 months. Mycological examinations were done before and after the treatment. Overall efficacy, tolerability, cosmetic acceptance and adverse effects were assessed at the end of 6 months' treatment. Results: The mean percentage of affected area decreased from 28.9% to 4.7%. Mycological cure rate was 77.8% at the end of the treatment. Overall efficacy assessed by physician and patients were similar and evaluated as complete cure in 48% and 44%, respectively. Tolerability and cosmetic acceptance were excellent or good in most of the patients. No systemic adverse effects were found, but 3 patients complained of mild prickling sensation or ingrowing toe nail. Conclusions: These data suggest that 8% ciclopirox nail lacquer is safe and effective in the treatment of mild onychomycosis.

박찬성,김경희,김미림 慶山大學校 1994 論文集 Vol.12 No.1

10^6 - 10^7 cells/ml of pathogenic bacteria, vibrio parahaemolyticus 10135, Staphylococcus aureus 196E and Listeria monocytogenes were exposed at 45, 50 and 60℃ for 60 minutes in tryptic soy broth(TSB). Following thermal stress, cells were allowed to recover in three kinds of recovery media for 24 hour. TSB, Flounder homogenate and Oyster homegenate were used for heat injured Vibrio parahamolyticus and Staphylococcus aureus where as TSB, Listeria enrichment broth(LEB) and Oyster homogenate for Listeria monocytogenes as recovery media. Heat injury of Vibrio parahamolyticus was larger Staphylococcus aureus or Listeria monocytogenes at 50℃. Recovery of heat injured cells of Listeria monocytogenes was laster than other strains. TSB was a good media for recovery of heat injured cells but Oyster homogenate was poor.

Process of construction project is made of plan, design, procurement, construction, and maintenance, which are closely related each other. for the success of project, each step of process should maintain the interface. The concept of constructability appeared in the practical business of an advanced country to maximize efficient integration. However, the concept of constructability in our country is not used in overall process to optimize each phase. To proceed the study, first, impact factors of constructability were identified, and had an interview with professionals. As a result, complexity of design in design phase, and responsibility of the contractors in construction phase are analyzed as the most important thing. Based on this result, I made secondary survey to identify the facts needs to be considered to applicate the analysis on the practical business. As the result of secondary survey, the ranking of considerations for application of practical business was identified. Therefore, this study suggested the basic direction to the applications of constructability.
