On filtrated and autoclaved water samples from Lake Jinyang, algal growth potential(AGP) test using Selenastrum capricornutum Printz were performed from February, 1999 to October, 1999 in order to assess fertility potential of the lake and to identify possible limiting nutrients. Algal growth potentials of the filtrated and filtrated after autoclaved samples were 0.018 ㎎/ℓ ~9.965 ㎎/ℓ and 0.018 ㎎/ℓ ~28.788㎎/ℓ respectively during surveyed period. AGP of the filtrated after autoclaved were higher than those of the filtrated only except some specific stations. The points of maximum growth were measured after addition of N, P and unenriched samples (control). The limiting factor was nitrogen only at site 5 in spring and phosphate appeared to be the major limiting nutrients in spike test throughout the year, especially during spring and autumn. Accoding to trophic level by Sudo(1980), the water quality of lake Jinyang were estimated mesotrophic at site 2, 4, 5, 6 in spring, at site 3, 6 in summer and at site 6 in autumn but all other sites were oligotrophic. But it is suggested that if we have not manigement of lake Jinyang, the water quality is possible to convert eutrophic.

We carried out a study on phytoplankton community at Owon stream, Jeollabukdo, Korea. The author have examined 83 taxa of the phytoplankton from researched area. These were composed of 5 classes, 11 orders, 21 families, 44 genera, 79 species, and 9 varieties. The composition of occurrence species were as follows: green algae are 48.2%, diatoms are 33.7%, blue green algae are 10.8% and etc(7.3%). Dominant species were Chlamydomonas angulosa, Pandorina morum, Coelastrum microporum, Scenedesmus quadricauda, Staurastrum gracile, Melosira varians, Me. italica, Synedra ulna, Sy. acus, Cocconeis placentula, and Cymbella tumida. The standing crops varied from 1,650cells/ℓ to 47,000cells/ℓ. Phytoplankton density of Owon stream were lower about 8.6 times to a 1,531 times than those of other lakes and rivers in Korea. So, to preserve the water quality in Owon stream we have to manage continuously on the nitrogen and phosphorus.

Some Korean traditional gruels contain Saealsim(rice ball). The Saealsim is made of glutinous rice usually. When such gruels are processed by industry, Saealsim must be stabilized by high temperature treatment and long term storage. In order to develop stabilized Saealsim, ratio of glutinous rice and nonglutinous rice of Saealsim and adding effets of six kinds of hydrophilic gums, two kinds prteins and two kinds of starches were investigated. The Saealsim in water was heated at 100℃ for 30 minuites and treated with repeating cycles of freezing and thawing. The solubles from Saealsim was determined, also Saealsim processed adding gums and proteins was evaluated by organolieptically. The moisture, crude ash and crude content in glutinous rice was slightly larger than those of nonglutinous rice. The amylose content of noglutinous rice was 23.7% and starch of glutinous rice was almost amylopectin. When the glutinous rice and nonglutinous rice were mixed differently at the ratio of 100 : 0, 75 : 25, 50 : 50, 25 :75 뭉 0 : 100, the solubles from Saealsim in retorted pouch at the ratio of 50 : 50 was smallest after six freeze - thaw cycles. When xanthan, guar, carrageenan, arabic gum, pectin and carboxymethyl cellulose was added to Saealsim, the solubles from Saealsim added xanthan gum was least therefore the xanthan gum was effetive to stabilized the Saealsim in water. When egg white, gelatin, pregelatinized starch and mungbean starch was added to Saealsim, the solubles from egg white was smallest. The optinum amount of xanthan and egg white added to Saealsim was evaluated 2% and 5% respectively. The interaction effect of xanthan and egg white was not observed. The sensory evaluation of taste, shape and texture of saealsim was flavored to the egg white 5% treatment.

The District Unit Planning(DUP) system, which was introduced in the revised Urban Planning Law in 2000, is a policy instrument for specific planning in a special area in urban setting. The main purpose of this study is to find better DUP in Man-duk in Busan. Through comparing two plans ; One is planned low buildings in Man-duk, the other is planned high buildings in the same; in Man-duk. To compare these plans, the study suggested to consider the several criteria and landscape-simulations. By comparing two DUP in Man-duk, the second plan was better for residents than the frist. DUP system is concerned with improving the urban spatial quality, but we have recognised that DUP system has some problems. There are many various types in urban area which is needed DUP system. Finally, based on this study, urban areas need the flexible application of DUP for each type and is considered the correlations of area-specific and goal-specific features. 현행 지구 단위계획의 목적은 용도지역제의 의 문제점과 한계 를 극복하고 당해 지역 토지의 효율적 이용과 주민의 안정된 주거환경 도모는 물론 인접지역과 조화를 창출하자는데 있다. 지역이 지구단위계획에 의해서 개발되면, 토지의 입체적 이용, 지구 내 기능의 적정 배분, 도시설계 상 융통성 부여, 그리고 지구 간 조화의 도모 등에 있어 무리와 경직성이 최소화 될 수 있다. 이로부터 토지의 효율적 이용에 의한 난개발 방지, 경관보전, 그리고 지역전체의 안정된 공간구성의 극 대효과를 얻을 수 있다. 최근 들어 많은 지역에서 지구단위계획의 수립이 요구되고 있으며 그 대상과 범위는 상이하다. 그러나 지구단위계획의 운용실태를 살펴보면 차별적 계획목표의 부재와 천편 일률적인 계획요소의 적용으로 많은 문제점 이 나타나고 있다- 따라서 본 연구는 하나의 연구 사례대상 지역을 선정하고 이 지역에 어떤 형태의 주거단지가 개발되는 것이 지역 전체의 조화를 창출할 것인지 를 파악코자 한다. 또한 주어진 대상지의 내적 조건상 어떤 유형의 개발이 효율적 토지이용의 최선인가 를 밝히고자 한다. 이 과정상 바람직한 지구 단위계획의 방향도 모색될 것이다.

기현균,손준성,오원섭,백경란,이남용,김성주,조재원,이석구,송재훈 대한감염학회 2004 감염과 화학요법 Vol.36 No.3

목적 : 최근 간이식 수요가 증가함에 따라 이에 대한 하나의 대안으로 생체 부분 간이식(LDLT) 시행례가 증가하고 있다. 이에 뇌사자 사체 간이식(OLT)과의 감염 양상을 비교하기 위하여 본 연구를 시행하였다. 방법 : 1996년 5월부터 2003년 8월까지 삼성서울병원에서 간이식을 시행 받은 284명의 환자들을 대상으로 후향적으로 분석하였다. 결과 : 188명은 LDLT를, 96명은 OLT를 시행 받았다. 간이식 후 감염증은 총 191명에서 발생하였고(67.0%) OLT 환자군과 LDLT 환자군 사이에 감염증의 발생 빈도와 원인 병원체의 빈도는 유의한 차이를 보이지 않았다. 병원체 별로는 Enterococcus 균정(16.2%) S. aureus(15.1%), coagulase negative staphylococci (13.4%)의 순서였다. 감염증의 종류는 복강 내 감염이 총 83례로 가장 많았는데, LDLT에서 OLT에 비하여 유의하게 높게 발생하였다(34.0% vs 19.8%, P=0.012). 요로 감염증(11.5% vs 4.3%, P=0.022)과 침습성 아스페르길루스증(7.3% vs 1.6%, P=0.034)은 OLT을 시행한 경우에 많았다. 기타 감염증은 통계적으로 유의한 차이가 없었다. 결론 : 간이식 환자에서 공여자의 종류에 따른 감염의 발생빈도는 차이가 없었으나 감염증 중 복강 내 감염은 LDLT에서 더 많이 발생하였다. 장구균 감염, 특히 반코마이신 내성 장구균이 간이식 후 발생하는 감염증의 중요한 원인 병원체임을 확인하였다. Background : Living donor liver transplantation (LDLT) has been performed more frequently to circumvent the shortage of donor organs. However, infectious complications after LDLT compared with orthotopic liver transplantation (OLT) have not been well investigated to date. Methods : We have retrospectively reviewed the medical records of all consecutive cases of liver transplantation, which had been performed at the Samsung Medical Center, Seoul, Korea, from May 1996 to August 2003. Results : Of the 284 patients enrolled, 188 (66.2%) underwent LDLT. Overall incidence of infectious complications after liver transplantation was 67.0% (191/284). Incidence of infections was not different between OLT group (67.7%) and LDLT group (67.0%) (P=0.9). Bacterial infections were the most common infectious complications (146 cases) followed by viral infections (32 cases), fungal infections (26 cases), and tuberculosis (4 cases). Enterococcus spp. (16.2%) were the leading pathogens followed by Staphylococcus aureus (15.1 %) and coagulase-negative staphylococci (13.4%). However, the distribution of etiologic agents was not different between OLT and LDLT group. Intra-abdominal infections (83 cases) were the most common type of infectious complications, which were more frequent in LDLT group (34.0%) than in OLT group (19.8%) (P=O.Ol). Conclusion : LDLT resulted in intra-abdominal infections more frequently than OLT. Enterococcus spp., especially vancomycin-resistant enterococci, are emerging pathogens in patients with liver transplantation.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

This study was conducted to compare the serum composition and urinary excretion in four institutional groups and the effects of intakes of good foods and harmful foods according to the Sasang constitution for a short time on serum and urine composition. The contitutions of 33 female students were classified by O-ring test and muscular strength test according to the Sasang constitution. The number of each institutional group was So-yang-in 11, So-em-in 10 and Tae-em-in 12. No subject belonged to Tae-yang-in. There were no significant differences among contitutional groups in the values of most serum composition and urinary excretion. Serum levels of total cholesterol, glucose, calcium and phosphorus in Tae-em-in was the highest among groups and the level of albumin and total protein in So-em-in was highest. The values of serum compositions changed after the 33 subjects took good foods and then harmful foods according to The Sasang constitution for a short time(5 days). Dietary behavior of the subjects had some effects among the constitutional groups in the values of most serum composition and urinary excretion. But the effects of dietary behavior on the serum composition and urinary excretion showed various trends in the four institutional groups.
