Column experiments were performed to investigate the influence of ionic strength on the attachment and detachment of Staphylococcus aureus to quartz sand and iron-coated sand. Experimental results showed that the mass recovery in quartz sand decreased with increasing ionic strength and bacteria detachment was occurred when ionic strength was changed. In the coated sand, however, the mass recovery remained constant even though ionic strength was changed. Also, no detachment occurred with ionic strength change.

Water is critically important for Tricholoma matsutake(Tm) growth because it is the major component of the mushroom by over 90%. The mushroom absorbs water through the below ground hyphal colony. Therefore, the objectives of our study were to investigate spatio-temporal water changes in Tm colonies. This study was carried out at Tm fruiting sites in Sogni Mt National Park, where the below-ground fairy-ring colonies have been irrigated. To identify spatial water status within the Tm soil colony soil moisture and ergosterol content were measured at six positions including a mushroom fruiting position on the line of the colony radius. To investigate temporal soil moisture changes in the soil colony, Time Domain Reflectometry(TDR) sensors were established at the non-colony and colony front edge, and water data were recorded with CRlOX data logger from late August to late October. Before irrigation, whereas it was 12.8% at non-colony, the soil water content within Tm colony was 8.0% at 0-5cm from the colony front edge, 6.2% at 10-15cm and 6.5-7.5% at 20-40cm. And the content was 12.1% at 80cm distance from the colony edge, which is similar to that at the non-colony. In contrast, ergosterol content which is proportional to the live hyphal biomass was only 0.4pg/g fresh soil at the uncolonized soil, while 4.9 ㎍/g fresh soil at the front edge where the hyphae actively grow, and 3.8 .㎍/g fresh soil at the fruiting position, l.l ㎍/g at 20cm distance and 0.4㎍/g in the 40cm rear area. Generally, in the Tm fungal colony the water content changes were reversed to the ergosterol content changes. While the site was watered during August to October, the soil water contents were 13.5-23.0% within the fungal colony, whereas it was 14.5-26.0% at the non-colony. That is, soil water content in the colony was lower by 1.0-3.0% than that in the non-colonized soil. Our results show that Tm colony consumes more soil water than other parts. Especially the front 30cm within the hyphal colony parts is more critical for soil water absorption.

자가면역성 간염은 대개 만성 경과를 가지며, 혈중 자가면역항체와 혈청 글로불린치의 상승, 그리고 조직학적으로 괴사 염증성 변화를 특징으로 하는 질환으로 아직 정확한 병인이 밝혀져 있지 않은 상태이다. 발병연령은 대개 젊은 영자(15-25세)에서 호발한다. 이 질환은 급성 간염의 임상경과를 보일 수 있으나, 심한 급성 간염이나 전격성 간염으로도 나타날 수 있는데, 이 경우 아주 나쁜 예후를 보인다고 한다. 치료는 자가면역성 간염 임상 경과의 다양성이나 병인, 병리기전의 불확실성에도 불구하고 대개 steroid 치료에 반응하는 것으로 알려져 있으며 대개 80%의 관해율을 나타내며 궁극적으로 간경변으로의 진행을 막을 수 있는 것으로 보인다. 저자들은 58세 남자에서 발생한 급성의 경과를 가지고 심한 황달을 동반한 자가면역성 간염을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Autoimmune hepatitis (AIH) is a chronic necroinflammatory liver disorder of unknown cause associated with circulating autoantibodies and a high serum globulin level. The age of onset of AIH show a peak between the age of 15 and 25 years. AIH can develop and be manifested as acute hepatitis, but severe form of acute hepatitis or fulminant hepatic failure has a poor prognosis. Although AIH is likely to progress from chronic active hepatitis to cirrhosis, steroid therapy can control the disease activity, prolong survival, improve the quality of life , and defer liver transplantation. In the present report we describe a 58-year-old man who admitted because of progressive jaundice and fatigue. He was diagnosed with AIH from laboratory test result showing positivity for antinuclear antibodies, anti-smooth muscle antibodies, and negativity for hepatitis viral markers and from liver biopsy. Steroid therapy, oral administration of prednisolone, was effective in improving the liver function test. Following liver biopsy 6 months after onset shows markedly improved necroinflammatory activity.

A 48-year-old male visited the emergency room of the authors’ hospital due to nausea, vomiting, and myalgia for four days. Acute hepatitis A was identified from the serologic marker of the hepatitis A virus. Mild elevation of the serum creatinine and creatinine phosphokinase(CPK) suggested rhabomyolysis, which was confirmed with the serum aldolase, myoglobin, and urine myoglobin. With supportive care, both the liver and renal func- tions were recovered gradually and fully. This case shows that rhabdomyolysis can be one of the mechanisms of renal complication in cases of acute symptomatic hepatitis A.

기종성 신우신염은 주로 당뇨병환자나 폐쇄성 요로질환을 가진 환자에 발생하며 특징적으로 신실질 및 그 주위조직에 가스를 형성하면서 심한 조직괴사를 일으키는 매우 드문 급성 화농성 신감염으로 사망률이 높은 질환이다. 이 질환은 1989년 Kelly와 MacCallum에 의해 처음 보고된 이래 외국문헌에 약 90례 정도가 보고되어 있으며 국내에는 28례가 보고되어 있다. 수액 및 전해질 보충, 인슐린 투여를 통한 적절한 혈당조절 및 항생제 투여등의 내과적 치료와 절개배농 및 신적출술등의 수술적 치료 방법이 있다. 내과적 치료로 가스의 감소가 없는 경우에는 즉각적인 수술적 치료를 시행하여야하므로 이 가스변화에 대한 추적관찰이 중요하다 하겠다. 본 저자들은 당뇨병환자에서 발생한 기종성 신우신염 1례를 내과적 요법을 치험하였기에 문헌고찰과 함께 보고하고자 한다. Emphysematous pyelonephritis is rare, life-threatening infection of the renal parenchyma and perirenal tisseue. This disease is characterized by the production of intrarenal and perirenal gas and is frequently encountered in patients with diabetes mellitus or urinary obstruction. We experienced a case of emphysematouse pyelonephritis in a 62 years old women with poorly controlled diabetes mellitus who had been managed with medical theraphy. So we report this case with a review of the referenced literatures.

신장이식은 환자의 삶의 질을 높이고 거의 정상적인 사회생활을 가능하게 함으로써 말기신부전 환자의 3가지 신대체 요법(혈액투석, 복막투석, 신장이식) 중에 가장 효과적이고 각광받는 치료법이라 할 수 있다. 최근 들어 의료기술과 의학의 발달로 신장이식의 성공률은 과거에 비해 비약적으로 높아지고 있으며 국내에서도 점차 신장이식수술을 받는 환자가 증가하고 있으나 서울이나 다른 대도시에 비해 의료환경이 열악한 중소도시나 지방의 병원에서는 아직도 시행하지 못하고 있는 형편이다. 이에 저자들은 경북 최초로 자체 의료진에 의해 고혈압과 말기 신부전으로 동국대 포항병원에서 혈액투석을 받고 있던 32세의 남자환자에게 부인으로부터 신장을 제공받아 신장이식을 성공적으로 시행하였기에 문헌고찰과 함께 보고하고자 한다. Kidney transplantation is the preferred treatment modality for many patients with end-stage renal disease (ESRD), because it offers improved quality of life over both hemodialysis and peritoneal dialysis. Patients who do well after transplantation generally report improvement in vitality and freedom to return to the style of life that they experienced before their progression to ESRD. Recently, the success rate of kidney transplantation is greatly being increased as the surgical technique and immunosuppressive drugs are developed. Kidney transplantation is also popular in Korea which has good result. But, until now the general hospitals which are located at small city can't try the kidney transplantation because they don't have proper facilities and experts. We firstly experienced a case of kidney transplantation in a 32 years old man with hypertension and chronic renal failure at KyoungBuk province. So we report this case with references.

舞臺裝置의 史的 考察

李昌九 淸州大學校 1985 論文集 Vol.18 No.2

The basic repertory of Greek architecture was in crease I in one respect only, the open-air theater achiered a regular, defined shape. Before the fourth century, the fourth century auditorium had simply been a natural slope, preferably curved, equipped with stone benches, now the hillside was provided with concentric rows of seats, and with staircase-aisles at regular intervals, as at Epidaurus. At the center is the orchestra, where most of the action took place. At the extreme right we see the remains of a hall-like building that formed the backdrop and supported the scenery. In terms of the stage setting, the Roman was similar to the Greek except that the Roman stage setting was more complicated and brilliant. I studied the literature on the drama, the changes of stage setting and the effect of stage setting on the drama from ancient times to the 20th century and I came to the conclusions as follows. Stage setting changes in accordance with the changes of the feature of each period. In ancient times, they had religeous Drama, in middle ages drama for entertainment in a pantomime, and in the 20th century they had modern drama with have various froms of expression. Stage setting has been in fluenced by the tides of art such as romanticism in the days of Renaissance, realism in the 19th century, surrealism and realism and symbolism in the 20th century. Stage setting has close relationship with the shape of stage. In ancient times stage setting had close relationship with the circle stage and the semecircle stage in the field, the moving stage in middle ages and the modern shape of theater in modern times. Architects and painting artists have contributed to the stage setting the architects in the days of Renaissance, the painting artists in the 19th century and the painting artists, sculptors and architects in the 19th century have contributed much to stage setting. Stage setting has been influenced by the development of stage engineering. The 19th century gave to the stage the realistic play and its fourth wall. The 20th century provided settings and lights, that were far more beautiful and expressive than anything the theater had known before. The new stagecraft made over the production methods of the theater of the civilized world. Also, it enabled plays to be written in new ways. It made the realistic drama more illusive, but it also helped the writer to develop a very different technique.

Seong-Jin Park,Chang-Hoon Lee,Myung-Sook Kim,Sun-Gang Yun,Yoo-Hak Kim,Byong-Gu Ko 한국토양비료학회 2016 한국토양비료학회지 Vol.49 No.6

The land use, land-use change, and forestry (LULUCF) is one of the greenhouse gas inventory sectors that cover emission and removals of greenhouse gases resulting from land use such as agricultural activities and land use change. Particularly, LULUCF-Cropland sector consists of carbon stock changes in soil, N₂O emissions from disturbance associated with land use conversion to cropland, and CO₂ emission from agricultural lime application. In this paper, we conducted the study to calculate the greenhouse gases emission of LULUCFCropland sector in South Korea from 1990 to 2014. The emission by carbon stock changes, conversion to cropland and lime application in 2014 was 4424, 32, and 125 Gg CO₂-eq, respectively. Total emission from the LULUCF- Cropland sector in 2014 was 4,582 Gg CO₂-eq, increased by 508% since 1990 and decreased by 0.7% compared to the previous year. Total emission from this sector showed that the largest sink was the soil carbon and its increase trend in total emission in recent years was largely due to loss of cropland area.
