양병은,유준영,송상훈,엄기훈 大韓顎顔面成形再建外科學會 1999 Maxillofacial Plastic Reconstructive Surgery Vol.21 No.4

The concept of PCA(Patient Controlled Analgesia) was first described in 1968, by Sechzer. The earliest descriptions of actual self-administered PCA machines were by Forrest et al. In gastric bypass surgery, cesarian section, orthopedic surgery etc, PCA is widely used in the control of postoperative pain. Previous Studies have shown that PCA provides effective pain-control for the postoperative patient. The postoperative pain-control is a problem that should be solved in surgery. Especially in orthognathic surgery, it is not same as in the case of maxillofacial trauma surgery or of tumor surgery : most orthognathic surgery patients are under operation not accustomed to pains, and difficulties in pain-complaint due to IMF(Intermaxillary fixation), postoperative nausea, and vomiting are additional problem. In this study, we have compared PCA and IM analgesics with respect not only to time request but also to the quality of postoperative pain control.

Renal artery thrombosis may result from external trauma of a blunt nature. Such injury is induced by rapid deceleration resulting in the stretching of the renal vasculature, disruption of the arterial intima-the least elastic layer of the arterial wall and eventual thrombosis. The treatment of renal artery thrombosis is controversial, with physician's options divided between prompt surgical exploration with vascular repair and clinical observation. We experienced 1 case of traumatic renal artery thrombosis and report that with a brief review of the literature.

The evidence of infarction within the territory of the posterior cerebral artery could be diagnosed clinically using follow-up CT scan in while it has been pathologically well proved entity when the tentorial herniation occurred particularly in cases of head trauma with intracranial hematoma, although its incidence was generally within 10%. Visual field defects in traumatic intracranial surface hematomas have been proposed as result of the compression of posterior cerebral artery or anterior cheroidal artery and directly optic tract or visual cortex. Authors experienced the infarction of occipital and temporal lobe on CT scans and the homonymous hemianopsia in 3 cases of 20 epidural hematomas after CT was available. The case histories and CT findings of the infarction were detailed and discussed. It may be stressed that the careful examination and frequent follow-up CT scan are performed even in epidural hematoma.

최대 토오크 운전을 위한 영구자석 동기전동기의 전류 위상각제어

이병송,김기용 서울産業大學校 1995 논문집 Vol.41 No.1

This paper describes current controlled PWM techniques of IPM synchronous motors for maximum torque operation. The IPM synchronous motors have a saliency,in which the q-axis inductance is larger than the d-axis inductance. As a consequence, there exists a reluctance torque component. when this component is added to the torque component produced by the stator currents and the air-gap flux, maximum torque will be increased. In this control technique, the current phase angle is controlled according to load conditions in order to use the reluctance torque effectively. Several characteristics such as torque, efficiency and are greatly improved by this control comparing with the conventional control technique. The maximum torque control strategy is analyzed and the performance is investigated by the computer simulation using actual parameters of a drive system. Simulation results are given and discussed.

This experiment was performed on analgesic, anti-pyretic, sedative, anti-swelling, anti-thrombotic, anti-tumor effect and response of isolated uterus by administrating high and low concentration of Sopokchukeotang's hot-water-extract to experimental animals. This administration purpose to investigate the efficacy of the Sopokchukeotang which is known as having effects on treating female genital diseases on basis of oriental medicine literature and its clinical use. The results obtained were as follows: 1. The writhing syndrome induced by acetic acid was decreased by administration of the Sopokchukeotang's hot-water-extract. However, there was no statistical significance between sample and control group. 2. The administration of the Sopokchukeotang's hot-water-extract elevated the pain threshold significantly by on hindpaw edema induced by 1% carrageenin in rat. 3. Abnormally elevated body temperature induced by thyphoid vaccine was decreased by the administration of the Sopokchukeotang's hot-water-extract. But, there was no statistical significance. 4. Sleeping time induced by Pentobarbital-sodium was prolonged by the administration of the Sopokchukeotang's hot-water-extract. However significant effect was recognized only in the treated by low concentration group(p<0.05). 5. The significant decrease of swelling induced by carrageenin was noted in the group treated by high concentration(p<0.05, p<0.01). 6. The group treated by low concentration showed significant anti-swelling effect on the swellings induced by yeast, but not in the group treated by high concentration didn't show it(p<0.05). 7. The serum FDP was decreased significantly by administrating the Sopokchukeotang's hot-water-extract to the experimental thrombosis(p<0.05, p<0.01). 8. The serum fibrinogen was increased significant by the administration of the Sopokchukeotang's hot-water-extract on the experimental thrombosis(p<0.01, p<0.001). 9. The prothrombin time was not influenced by the adminstration of the Sopokchukeotang's hot-water-extract on the experimental thrombosis. 10. The administration of the Sopokchukeotang's hot-water-extract did riot make a prolongation the survival in Saroma 180 ascitic tumor implanted Rats. 11. The administration of the Sopokchukeotang's hot-water-extract had no effect on the normal movement of the isolated uterus. However, it showed the relaxation effect on the oxytocin induced muscle contraction of the isolated uterus. According to the above results, it might be recognized that the Sopokchukeotang's hot-water-extract has the effect of analgesia, anti-pyrexia, sedation, anti-swelling, anti-thrombosis and relaxation effect on the oxytocin induced contraction of uterus muscle. However, anti-tumor effect of Sopokchukeotang's hot-water-extract was not appeared in the experiments. According to the above results. Sopokchukeotang's not-water-extract can be applied on the various inflammatory diseases in female genital organs.

한국 근로자의 人的資本 形成에 관한 연구

Lucas(1988)에 의하면 미국의 경우 인적자본 증가의 64%가 학교교육의 내부효과에 의한 것이었고 나머지 36%가 생산현장의 인적자본 축적에 의한 것이었다. 같은 추정 방식을 우리나라에 적용하면 학교교육은 16%에 지나지 않았고 84%가 생산현장에 의한 것이었다. 본 논문은 생산현장에서의 학습에 대한 하나의 모형을 제시하여, 위와 같은 한국노동자의 인적자본 축적과정을 이론화하는 시도를 하였고 이 모형의 경제성장에 대한 함의를 논의한다. 생산현장에서 미숙련 노동자가 숙련 노동자로부터 배우는 것에 의해 인적자본이 축적되면 경제성장률은 인구증가율과 역의 관계에 있다. 이 학습에 대해 미숙련 노동자가 숙련노동자에게 수업료를 지불하면 연령-수입 단면은 연령-생산성 단면으로부터 괴리된다. 횡단면 연령-수입 단면의 기울기는 경제성장률이 높을수록 낮지만, 이 괴리의 적절한 측정인 노동자의 생애에 걸친 연령-수입 단면의 기울기의 연령-생산성 단면의 기울기에 대한 비율은 경제성장률과 무관하다. 노동자들의 학습능력이 다르고 고용될 때는 사용자가 그 학습 능력을 관찰할 수 없는 경우도 분석하고 경제성장률에 대한 함의를 논의하였다. According to Lucas(1988), 64% of American human capital increase is attributed to the internal effects of schooling, and the remaining 36% to the human capital formation in the work place. If a similar estimation is used for Korean data, only 16% of Korean human capital increase is attributed to schooling while the remaining 84% is attributed to the human capital formation in the work place. This paper tries to theorize "on-the-job-learning" and shed some light on the human capital formation in the work place, especially Korean workers' human capital formation on the job. We examine two varieties of a model. This first one assumes homogeneity amongst workers, and the second one assumes heterogeneity.

온도상승에 따른 마감재의 세공구조 특성에 관한 연구 : 석고보드를 중심으로 Focusing on Gypsum Boards

김광기,박선길,김근허,송병창,정상진 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.1(구조계)

On fire, the most significant materials influencing the rise of temperature are finishing materials, and highly combustible materials become the reason of magnifying fires compared to incombustible materials. Recently, gypsum boards are widely used as interior finishing boards for constructions because of their features of absorbing heats and little temperature rising at the early stage of fire. Therefore, in this research, basic data were suggested to secure fireproof stability by investigating interior processing features, which change together with the backside temperature of test materials from Flash Over(within 30 minutes after firing), at which temperature reaches its highest point, to survey the features of materials due to rising temperature in the chase of gypsum boards (general and fireproof gypsum board)

李炳基,朴鶴封,宋鎭水 全北大學校 1984 論文集 Vol.26 No.-

Effects of 2,4-dichlorophenoxyacetic acid(2,4-D) and kinetin on the induction and growth of calluses of Tulipa gesneriana cv. Golden Apeldoorn were investigated in vitro. Style tissues were cultured on Murashige and Skoog's media containing various levels of 2, 4-D and kinein. The calluses were induced vigorously from the medium supplemented with 1-2mg/ι 2,4-d and 0.5-lmg/ι kinetin, Espcially, the friable calluses like protuberance were formed from the medium containing 2mg/ι 2,4-D and 1mg/ι kinetin. The poor calluses were initiated from the medium supplemented with 1mg/ι 2,4-D or 1mg/ι kinetin only.
