생명권과 자기결정권, 그리고 의사의 진료의무

유승룡 대한의료법학회 2008 의료법학 Vol.9 No.2

Based on foreign examples and past debates, the minimal conditions for passive euthanasia can be suggested as following; ① The patient is incurable by modern medical practice and his death is impending (less than 6 months), ② Euthanasia is practiced solely to relieve physical pain of the patient, ③ If the patient can express his will, there should be a clear and sincere request or consent, ④ More than 2 doctors including doctor in charge should consent, ⑤ Euthanasia should be practiced in ethical way, ⑥ Patient family should agree(when the patient will is assumed.) It is hard to resolve issues regarding euthanasia based on past rulings and cases without concrete law. As in United States and Germany, clear and objective provisions of euthanasia and definitive method for patient's advanced directive should be legislated to resolve medical conflict and to relieve patient and family from agony. And death with dignity debate will not be able to proceed if it is only substantively approached because of unclear definition of euthanasia and benefit comparison way of thinking. Thus it is important to establish definitive process to decided legislation of euthanasia act and resolving conflicts arising from each step of the process among interested parties exchanging medical/ethical opinions.

The purpose of this study is to develop a new seismic resistant method by using precast concrete wall panels for existing low-rise, reinforced concrete beam-column buildings such as school buildings. Three quasi-static hysteresis loading tests were experimentally performed on one unreinforced beam-column specimen and two reinforced specimens with L-type precast wall panels. The results were analyzed to find that the specimen with anchored connection experienced shear failure, while the other specimen with steel plate connection principally manifested flexural failure. The ultimate strength of the specimens was determined to be the weaker of the shear strength of top connection and flexural strength at the critical section of precast panel. In this setup of L-type panel specimens, if a push loading is applied to the reinforced concrete column on one side and push the precast concrete panel, a pull loading from upper shear connection is to be applied to the other side of the top shear connection of precast panel. Since the composite flexural behavior of the two members govern the total behavior during the push loading process, the ultimate horizontal resistance of this specimen was not directly influenced by shear strength at the top connection of precast panel. However, the RC column and PC wall panel member mainly exhibited non-composite behavior during the pull loading process. The ultimate horizontal resistance was directly influenced by the shear strength of top connection because the pull loading from the beam applied directly to the upper shear connection. The analytical result for the internal shear resistance at the connection pursuant to the anchor shear design of ACI 318M-11 Appendix-D except for the equation to predict the concrete breakout failure strength at the concrete side, principally agreed with the experimental result based on the elastic analysis of Midas-Zen by using the largest loading from experiment.

This study aims at developing a new seismic resistant method by using precast concrete wall panels for existing low-rise, reinforced concrete beam-column buildings such as school buildings. Three quasi-static hysteresis loading tests were performed on one unreinforced beam-column specimen and two reinforced specimens with U-type precast wall panels. Top shear connection of the PC panel was required to show the composite strength of RC column and PC wall panel. However, the strength of the connection did not influence directly on the ultimate loading capacities of the specimens in the positive loading because the loaded RC column push the side of PC wall panel and it moved horizontally before the shear connector receive the concentrated shear force in the positive loading process. Under the positive loading sequence(push loading), the reinforced concrete column and PC panel showed flexural strength which is larger than 97% of the composite section because of the rigid binding at the top of precast panel. Similar load-deformation relationship and ultimated horizontal load capacities were shown in the test of PR1-LA and PR1-LP specimens because they have same section dimension and detail at the flexural critical section. An average of 4.7 times increase in the positive maximum loading(average 967kN) and 2.7 times increase in the negative maximum loading(average 592.5kN) had resulted from the test of seismic resistant specimens with anchored and welded steel plate connections than that of unreinforced beam-column specimen. The maximum drift ratios were also shown between 1.0% and 1.4%.

The extent of utilization of computers at clinics (physicians' office) setting in Korea has not yet been studied. Lack of such information hinders developing effective strategic plans for implementing Information and Communication Technology(ICT) to physicians office practice. Therefore this study was conducted to elucidate current status of computer use in physicians office practice. A mail survey was carried out to randomly selected 2,000 members of Korean Medical Association and 26.3% responded. The results showed that percent of clinics currently using computers and internet for the clinical practice was 98.0% and 85.2%, respectively. With recent gain of popularity in using computers and internet in public, more than 50% of respondents thought that transmission of sensitive medical information through internet was acceptable. Ninety six percent of respondents utilized computerized health insurance claims and electronic medical record system. However, 36.3% of respondents was keeping paper form patients medical records in addition to the computerized records to meet regulatory requirements.Overall, this study seems to indicate that physicians in practice show a strong interest in computerization, although the adaption of ICT in the field of medicine is relatively slow. In conclusion, physicians office practice can be a potential area for future ICT application.

PS 강선의 정착부착성능에 관한 해석 모델

유승룡 한국콘크리트학회 1994 콘크리트학회지 Vol.6 No.4

A new analytical model is proposed to better understand the transfer bond performance in a prestressed pretensioned concrete beam. The transfer length is divided into an elastic and a plas tic zones in this model. The bond stress is assumed t.o increase proportionally with the slip t.o the lirnit of maximum bond stress within the elastic zone and remains at a constant maximum value wthin the plastic zone. Four main stress patterns: bond stress, slip, steel stress, and concrete stress distributions within the transfer length are obtained precisely. The total transfer length al\ulcornerd free-end slip obtained here give a close comparison to the test results by Cousins et al. PS 강선의 정착부착성능에 대한 새로운 해석방법을 소개하였다. 이 모델에서, 정착부착 길이는 탄생 영역과 소성영역으로 구분되었다. 탄성영역에서 부착응력은 최대 부착응력에 도달된 때까지 슬립과 비례하여 증가하고, 소성영역에선 최대 부착응력으로 균일하게 분포됨을 가정하였다. 정착부착 길이 내에서 부착응력, 슬립, 강선응력, 콘크리트응력 분포를 결과를 얻을 수 있었고, 전체 정착부착 길이와 자유단에서 슬립에 대한 결과치는 최근 Cousins et al.의 실험 결과치와 유사하였다.
