Background: Recently the health insurance review agency tried to cut off the cost of unnecessary hospital stay. It is important to reduce the prolonged occupation of the hospital beds. However, there are some obstacles of the management for the prolonged bed occupation. We report our experiences and the problems of bed-control. Methods: To increase the rate of effective bed-usage, a task force was made. This team was consisted of 4 dctors, 2 nurses and 2 personnel of the administrative department. From December 20th 2001 to May 17th 2002, the task force analysed the rate, number and causes of the prolonged (more than 60 days, regardless of the disease entities) bed occupation. We announced and explained the necessity of bed-control and actively pressed to reduce the prolonged bed occupation. Results: The number of the prolonged bed occupation was 71 at the beginning of the management. It was reduced to 46 at best, then turned back to 65 at the end. It seems to be impossible to reduce the prolonged bed occupation until there are sufficient numbers of long-term care facilities. Aggressive bed control makes the sick patients to move every two or three months, it is never desirable. Conclusion: We cannot expect any Quality Improvements without improvement of the wrong system. Prior to the management for the prolonged bed occupation, it is necessary to build a sufficient number of long-term care facilities.

몬트리올 의정서에 의해서 규제받는 Halon-1301과 대체 물질중의 하나인 CO_2의 물성(밀도, 점도, 엔탈피)의 실험식을 구하였다. 문헌에서 얻은 실험값을 이용하여 온도에 대한 회귀분석에 의해서 실험식을 얻었다. 압축인자를 이용하여 온도에 대한 2차 함수로서 밀도에 관한 실험식을 제안하였다. 점도는 온도에 대한 지수함수로 표시되며, 보정인자를 사용하여 사용 온도범위를 확장하였다. 엔탈피는 열용량과 마찬가지로 온도에 대한 2차 함수로 정의하여 나타내었다. 본 연구에서 제안된 위의 실험식의 상관계수는 0.99이상이었다. For Halon-1301 regulated by Montreal Protocol and CO_2 as its alternatives, the empirical equations of density, viscosity, and enthalpy were correlated in terms of temperature. They were obtained by regression analysis from the experimental data in the literature. The empirical equation of density was expressed as compressibility factor by the second- order function of temperature. The empirical equation of viscosity was formulated as a power function, and a correction factor was considered to cover the wider range of temperature. Finally, heat capacity as well as enthalpy were well fitted by empirical form of the second-order temperature. The correlation coefficients of the equations in this work were more than 0.99.

As the first female artist of Western painting in the modern times, Hey-seok Na is the historical figure in Suwon, who went ahead of the times. Suwon City established the street of Hey-seok Na to commemorate her, in Ingye-dong, Paldal-gu. Street-establishment business for the historical figures is one of the factors with the biggest effects for the creation of local cultures. It has many merits such as the offer of fine view of city and resting area as well as giving the pride and educational effects to its residents. However, there are memorial hall or exhibitional hall not established in the street of Hey-seok Na, with the lacks in attractions and convenience facilities. With a poor decorative arrangement in the vicinity of the street, the meaning of street establishment and the image of Hey-seok Na are not well-delivered. Accordingly, the initial plan to make the street with citizens has not been well carried out. This research classified and analyzed the achievements and thoughts of Hey-seok Na, to embody it as the image and the concept of design to be expressed for the street was picked out. As a result, the image of Hey-seok Na, as the historical figure was set at modern times. the existing facilities in the street of Hey-seok Na was analyzed, centering on the time-factor of the modern times, deciding the spacial goal pursued by the street along with things to be improved.

The case in which patients present clinical, biological, and histological features of both primary biliary cirrhosis (PBC) and autoimmune hepatitis (AIH) is rare. Such overlap syndrome is believed to be associated with a poor prognosis. We report a case of PBC-AIH overlap syndrome associated with IgA nephropathy. The patient showed hepatitic and nephritic features including easy fatigability, pruritus, icteric sclera and gross hematuria. The liver biopsy showed chronic hepatitis with piecemea necrosis and bridging necrosis. The clinical data of high titers of antinuclear antibodies and antimi tochondrial antibodies, elevated serum IgM and recurrent pruritus, suggest mixed features of AIH and PBC. IgA nephropathy was confirmed by renal biopsy. High dose of corticosteroids was effective initially, but clinical symptoms were relapsed after tapering the administration of corticosteroids. Thus, azathioprine was administered at a dose of 2 mg/kg/day. A dramatic improvement was noted in clinical conditions and liver tests.
