The aim of this research is to attain the basic information for weight prescription resulting from applying the method of dividing 14 university students, who hasn't been physically trained, into two groups, comparing with isokinetic muscular function and body tone according to their body condition over the 8 weeks during which the subjects are physically trained. The obtained conclusions were as follows; 1. Finishing this program over the 8 weeks, the subjects made a meaningful difference in the aspects of group within time body fat quantity, relative body fat, abdominal body fat, protein quantity and mineral quantity with the days going an but the difference is almost none only in body water quantity. When it comes to the interaction group between time and groups, there are no meaningful difference in all those things above(body fat quantity, relative body fat, abdominal body fat, protein quantity, mineral quantity and body water quantity). And it showed that there was no meaningful difference between the two groups, A and B. 2. After adapting 8 weeks long program, I acquired a meaningful result of group within time knee joint right and left flexion muscular strength, left extension muscular strength, right and left flexion·extension muscular power, right and left flexion muscular endurance. Speaking about the interaction between time and groups, there existed a meaningful difference in knee joint right and left flexion muscular strength, left extension muscular strength, left flexion·extension muscular power. On top of this, there was also a fruitful difference in knee joint right extension muscular strength, left extension muscular power. 3. Having the 8 weeks groups training program, the subjects had the following results. In the view of abdominal muscular function group within time, abdominal flexion·extension muscular strength, abdominal flexion·extension muscular power, abdominal flexion·extension muscular endurance made a meaningful change. When it comes to the mutual action going between time and groups, there were meaningful changes in abdominal extension muscular strength, abdominal flexion muscular power, abdominal flexion·extension muscular endurance. But there was no difference between the two groups, A and B.

Objective : The aim of this study were to measure quality of life(QOL) in liver transplant recipicnts, to ocmpare QOL between living donor liver transplant recipicnts and cadavcric live transplant recipients and to investgatre whether SF-36 may be used as a disease-specific instrument in liver transplant recipients. Methods : We conducted a single-center cross-sectional study of 133 LT recipients ages 13 to 65 years, all of whom had had Liver Transplantion(LT) at least 1 months previously. QOL was assessed using a self-completion questionnaire consisting of the Bang Whal Ran(1991) instruments and the 36-Item Short-Firm Health Survey(SF-36) health status profile measure. We investigated whether the SF-36 instrument may be used as a disease-specific instrument in LT recipients. Individual scale scores range from 0 to 100 , with higher score reflecting better health. Data on demograpics, clinical status at pre transplantation 1 day, post transplantation clinical statns, and graft gunction were collected to identify predictors of post transplantation QOL. Results : Standard measures for test-rtest reliability, internal consistency, and discriminant and concurrent validity were examined. The reliability of the SF-36, as measured by test-retest correlation(Pearson coeffocoents: 0.729, p=0.002) and by internal consistency (Cronbach's alpha: 0.9431) exceeded conbentional acceptability criteria. The correlation between domain scores of SF-36 and the Bang Whal Ran(1991) was clear and logical in that the clinical characteristics of SF-36 strongly correlated with the clinical component summary score of the Bang Whal Ran(1991)(r = 0.8155, P<01). SF-36 scale scores were compared between Cadaveric Liver Transplant recipients and Living Donor Liver Transplant recipients. Donor types of post LT did not influence HRQOL(P >0.05). 87% of the liver transplant recipients were safisfied to get LT. Satisfaction of post LT showed significantly greater HRQOL(p<0.001). Conclusion : SF-36 is found reliable and valid. This study indicates thet Donor Type did not influence HRQOL after LT. The information gained from this study will help us to better define expectations and the colinical course after liver transplantation to patients and their families.

배재근,김준호,정일래 서울産業大學校 2005 논문집 Vol.54 No.3

본 연구에서는 이전의 Leclercia adecarboxylata균을 이용한 암모니아 악취 가스의 제거 가능성 검토 결과를 바탕으로 현장 적용을 위하여 미생물 배양배지의 조성을 달리하여 경제적인 배지성분을 얻고자 하였다. 이전의 가능성 검토 결과 연속적으로 암모니아 악취 가스가 1,000ppm으로 주입되어도 반응기내 암모니아성 질소의 농도가 증가하지 않고, 일정 수준 계속 유지 되는 것을 알수 있었다. 우선 연속식 실험에 앞서 R1에 최적 GA배지 주입량을 결정한 실험과 증류수만을 넣은 R2에서 배지내 NH4-N의 농도가 증가하지 않고, 일정하게 유지되는 것으로 나타나 제거효율적인 측면 GA배지를 주입하는 것이 가장 바람직 한 것으로 나타났다. 2번째 실험인 R2에 증류수와 글루코스 1g/L만을 넣었다. 3번째 실험은 배지내 들어가는 약품의 비용을 줄이기 위한 실험으로 R2에 미량 K₂HPO₄ 3g/L와 글루코스 1g/L, 증류수만을 넣고 실험을 하였다. 본 연구에서는 배지내 미량의 원소를 제외한 소량의 K₂HPO₄만으로도 미생물 성장이 GA배지를 넣었을 때 보다 성장이 느리긴 하지만 성장이 이루어 지는 것을 알수 있었다. 이 결과를 바탕으로 향후 탈취탑 설계에 다른 원소를 제외하고 K2HPO4만으로 효과를 얻을 수 있어 경제적인 측면에서도 가능성을 검토할 수 있었다.

Among the total 36 cases, 20 cases showed positive urease reaction from CLO-test and 19 cases were ureas positive from modified urea agar. 16 cases were urea negative specimen.

중성자에 조사된 원자로 압력용기 재료(SA508)의 Magneto-acoustic emission 효과

홍준화,박덕근,옥치일,김장환,이종규 韓國非破壞檢査學會 1999 한국비파괴검사학회지 Vol.19 No.6

원자로 압력용기 재료인 SA508 steel을 온도 70 ℃와 대기압하에서 최고 10 n/㎠까지 중성자를 조사시켜 조사량에 따른 미세경도 변화와 magneto-acoustic emission(MAE) 에너지를 측정하였다. 중성자 조사에 따른 경도의 변화는 조사량이 10 /㎠까지는 거의 일정하였으나, 조사량이 10 /㎠이상에서 급격히 증가하였다. MAE 에너지의 변화는 중성자 조사량에 따라 경도의 변화와 같은 형태로 변하였으나 그 변화량은 감소하여 그변화의 추이는 경도의 변화와는 역의 형태였고, 또한 MAE에너지의 상대적 변화와 경도 변화사이에는 아주 좋은 선형성을 보였다. 이러한 결과에서 SA508 강재는 10 /㎠이상의 중성자에 조사될 경우에 재료에 중성자 조사에 의한 미세 결함이 급격히 증가하여 전위(dislocation)이동에 대한 저항성을 나타내는 마찰경화의 증가가 경도의 증가를 유발하고, 또한 이러한 미세 결함은 자기장과의 반응에서는 90°자벽의 운동중에 자기탄성 변화를 유도하여 MAE 에너지의 감소를 유발함을 알 수 있었다. 그리고 경도의 변화량보다 MAE 에너지의 변화량이 더 크게 나타나, 중성자 조사에 의한 미세결함은 기계적 성질보다 자기적 성질에 더 민감하게 반응한다는 것을 알 수 있었다.따라서 MAE가 중성자 조사에 의한 재료의 미세 구조 결함을 비파괴적인 방법으로 평가하는 강력한 도구의 가능성이 있음을 알 수 있었다. Magneto-acoustic emission (MAE) energy and hardness were measured in the reactor pressure vessel steel (SA508 Steel) for the various neutron fluence, irradiated dose up to 10 n/㎠. The hardness was nearly a constant up to 10 n/㎠, but it was rapidly increased with an increase of the neutron irradiation above 10 n/㎠. It may be considered that the increase of hardness is due to the hindrance of dislocation motion induced defect clusters by irradiation. On the other hand, the MAE energy was slowly decreased as the neutron irradiation increased up to 10 n/㎠ and it was rapidly decreased with an increase of the neutron irradiation increased up to 10 n/㎠ and it was rapidly decreased with an increase of the neutron irradiation above 10 n/㎠. The decrease of the MAE energy may be considered as an increase of the defect clusters which is very sensitive to the 90°domain wall motion. Furthermore, the change of MAe energy and hardness had nearly a linear relationship, but the change of MAE energy was more significant than the change of the hardness. Therefore, MAe may be considered as a very useful technique for the nondestructive evaluation of irradiation damage.

김삼용,길준영,전의건 충남대학교 의과대학 지역사회의학연구소 1991 충남의대잡지 Vol.18 No.2

A retrospective analysis of clinical data of 32 cases of aplastic anemia diagnosed at Chungnam National University Hospital from August 1985 to July 1991 was done. 1) The highest incidence of aplastic anemia was seen in the third decade and 25 cases of patients (78.2%) were below 40 years of age. The incidence decreased in older age groups. 2) Exposure to possible toxic agents were seen in 6 cases(18.8%), among which benzene was related in 2 cases(6.3 % ), herb drug in 2 cases(6.3 % ), acute viral hepatitis(type B) in 1 case(3.1 % ), antifungal agent in 1 case(3.1 % ). 3) Initially all patients were treated with oxymetholone with or without prednisolone and supportive care. Eleven(37.9 %) out of twenty-nine patients showed responses(CR: 17.2%, PR: 20.6%). Nine out of the eighteen patiens who did not respond to androgen therapy were treated with antilymphocyte globulin (ALG) plus methylprednisolone. Two patients(22.2 %) out of 9 showed complete responses. 4) Overall responses of present series of patients was 44.8 % (androgen± prenisolone therapy: 37.9%, ALG+ methylprednisolone: 6.9%). The actuarial survival of all patients at 72 months was 83.4%. The median survical rate of severe aplastic anemia(32 months) was similiar to that of moderate aplastic anemia(37 months). 5) Factors associated with favourable survival were male sex and presence of etiological factor. Since the prognosis of aplastic anemia in Korea is quite favorable, randomized controlled study would be needed to define the therapeutic roles of bone marrow transplantation of immunosuppressive therapy in patients with severe aplastic anemia in Korea.

초경량성 재료인 Mg-10Li-3A1 합금의 TMP 처리를 통한 기계적 특성 향상 방안

김광배,홍준표,김영인,홍원식,배현근 한국 항공대학교 항공산업기술연구소 1998 航空宇宙産業技術硏究所 硏究誌 Vol.8 No.-

초경량 고강도 Mg-10Li-3Al 합금이 용탕단조법에 의해 제조되었다. 주도된 상태의 미세구조는 β상 기지에 균일하게 분포된 AlLi 및 MgAl₂Li를 포함하는 HCP α상과 BCC β상으로 이루어졌다. α상의 초기 결정립 크기는 100㎛였다. Mg-Li 합금에 Al을 첨가하는 것은 용체화 처리 및 시효를 통한 석출 경화에 기인하여 합금의 강도 및 경도를 향상시켰다. 결정립 미세화를 위한 TMP처리가 냉간 가공과 연이은 300℃, 30분 동안의 어닐링에 의해 수행되었다. 결과적으로 나타나는 미세구조는 재결정화되지 않은 α상과 재결정화된 β상으로 이루어졌다. 냉간 가공량이 증가함에 따라 합금의 결정립 크기가 감소하였고, 최종 결정립 크기는 3.5㎛였다. 가공 열처리된 Mg-10Li-3Al합금은 용탕단조된 합금보다 높은 강도와 연신율을 보였다. Superlight and high strength Mg-10Li03Al alloys were fabricated by squeeze casting. The as-casted microstructure was consisted of a mixture of a mixture of HCP α and BCC β phases including AlLi and MgAl₂Li precipitates, which were uniformly distributed in the βmatrix. Initial grain size of α phases was 100㎛. The addition of Al in Mg-Li alloy had improved the strength and hardness due to the precipitation hardening through solution heat treatment and aging. Thermomechanical Processing(TMP) for grain refinement was carried by cold working and immediate annealing for nucleation at 300℃ for 30 minutes. Subsequent microstructure was consisted of unrecrystallized α and recrystallized β phases. The more the amount of cold working increased, the more the grain size of the alloy was decresed. Final grain size was 3.5㎛. Thermomechanically processed Mg-10Li-3Al alloy had higher strength and elongation than as-casted alloy.

박성희,서준규,윤혜설,홍진영,박군제 한국의료QA학회 1998 한국의료질향상학회지 Vol.5 No.2

Purpose : To shorten processing time for variety of medical affairs of the patient at the outpatient clinic of a big hospital is very important to qualify medical care of the patient. Therefore, patient's waiting time for drug delivery after doctor's prescription is often utilized as a strong tool to evaluate patient satisfaction with a medical care provided. We performed this study to investigate factors influencing patient satisfaction related with waiting time for drug delivery. Methods : The data were collected from July 21 to August 12, 1998. A total 535 patients or their families who visited outpatient clinics of Inha University Hospital were subjected to evaluate the drug delivery time and the level of their satisfaction related, which were compared with those objectively evaluated by Quality Improvement Team. The reliability of the scale was tested with Cronbach's alpha, and the data were analyzed using frequency, t-test, ANOVA, correlation analysis and multiple regression. Results : The mean drug delivery time subjectively evaluated by the patient (16.1 13.0 min) was longer than that objectively evaluated (10.9 7.6 min) by 5.2 min. Drug delivery time objectively evaluated was influenced by the prescription contents, total amount or type of drug dispensed, etc, as expected. The time discrepancy between two evaluations was influenced by several causative factors. One of those proved to be a patient's late response to the information from the pharmacy which the drug is ready to deliver. Interestingly, this discrepancy was found to be more prominent especially when waiting place for drug delivery was not less crowded. Other factors, pharmaceutical counseling at the pharmacy, emotional status or behavior of a patient while he waits for the medicine, were also found to influence the time subjectively evaluated. Regarding the degree of patient satisfaction with the drug delivery, majority of patients accepted drug delivery time with less than 10 min. It was also found to be influenced by emotional status of the patient as well as kindness or activity of pharmaceutical counselor. Conclusion : The results show that, besides prescription contents, behavior pattern or emotional status of a patient, environment of the waiting place, and quality of pharmaceutical counseling at the pharmacy, may influence the patient's subjective evaluation of waiting time for drug delivery and his satisfaction related with the service in the big hospital. In order to improve patient satisfaction related with waiting time for drug delivery, it will be cost effective to qualify pharmaceutical counseling and information system at the drug delivery site or waiting place rather than to shorten the real processing time within the pharmacy.
