Necrotizing pancreatitis develops in about 10-20% of patients with acute pancreatitis, and pancreatic abscesses develop in 3% of them. The mortality of pancreatic abscess has been reported up to 40% in one study. Recently, there are several reports that show good results with n on-surgical therapy, such as percutaneous drainage and endoscopic drainage, but if the non-surgical drainage fails, surgical therapy are recommended. However, there is no definite therapeutic method which is suggested yet so far after the failure of the surgical drainage. So we report the case in which we experienced successful treatment of pancreatic abscess by endoscopic removal of necrotic tissue through the gastrocystostomy, after the failure of the surgical debridement and internal drainage through gastrocystostomy.

Steroid cell tumor is a rare ovarian sex cord-stromal tumor which accounts for 0.1% of all ovarian tumors. Until now, only 4 cases have been reported in domestic literatures. Steroid cell tumor often secrets testosterone and presents virilization in adult women or precocious puberty in children. Treatment is often performed by surgical removal, adjuvant chemotherapy and radiation, but completely accepted treatment was not existed. We experienced a case of steroid cell tumor, which was manifested by typical virilization in a 43-year old patient, who was previously performed hysterectomy and unilateral oophorectomy. So, we present with a brief review of the literatures.

A flow sensor for detecting the flow rate of a air, composing a substrate, a heating element, and one or two fluid temperature sensing elements disposed symmetrically around the heating element. Wherein resistence changes by a fluid temperature change and heating element is maintained at fixed level by the control of voltage that is applied to the heating element. The function of the heating element(microheater) is based on the self-heating effect of the resistor when current is applied to it. A airflow sensor is capable of accuritely measuring a air flow irrespective of changes in ambient temperature. Pt thin films were deposited by a DC magnetron sputtering with Ar/O_(2) gas mixtures. Due to the oxygen incorporation into the Pt films, deposition rate and resistivity of as-deposited Pt thin films increased with oxygen fraction in the sputtering gas.

The distributed species and the kinds of variable microorganism in Pharynx were monitored to the elementary school child. Our purpose was to investigate the distribution of bacteria in Pharynx of child except for adults. Analysis performed the collected sample from 15 students in Chungnam area for 2 days from July 30 to July 31 in 2012. The isolated bacteria were identified by Gram stain and biochemical test using VITEKⅡsystems. The experiment on microorganism concentration of contact parts carried out and the average of total microorganism was measured. The elementary child's Pharynx were isolated and identified. The isolation rates were major distributied to Gram positive cocci, another Gram negative bacilli and Gram positive bacilli. respectively. The frequently isolated bacteria were G. adiacens. The Granulicatella adiacens is one of the fastidious Gram positive cocci previously described as nutritionally variant streptococci due to their requirement of L-cysteine, pyridoxal, or thiol compounds for growth. These bacteria have been identified as significant causative agents of endocarditis, opthalmic infections, and meningitis. Further systematic studies are necessary with an emphasis on species identification. Key Words : Microorganism, Elementary child, Pharynx and Larynx

서미자,김기덕,김남성,박수진,채순용,윤영남 충남대학교 농업과학연구소 1999 농업과학연구 Vol.26 No.2

온실가루이의 외부형태적 특징을 주사전자현미경 사진을 통해 관찰하였다. 우선 이들은 포탄모양의 알을 산란하는데 짧은 갈고리모양의 구조에 의해 잎 뒷면에 붙어있는 것이 확인되었다. 촉각의 길이는 0.3㎜로 전체가 6마디로 구성되어 있고, 첫마디는 굵고 짧으며 둘째 마디부터 가늘고 긴 채찍모양을 하고 있다. 끝마디인 6번째 마디의 끝에는 길이가 10㎛정도의 가늘고 비교적 긴 감각기를 가지고 있어 기주를 탐색하는 과정에서 식물체의 표면을 탐지하는데 사용하는 것으로 사료되며, 바로 밑부분에는 길이가 7-8㎛정도의 비교적 굵은 감각기 2개가 존재하고 있는 것으로 확인되었다. 이 감각기는 반대편에는 존재하고 있지 않은 비대칭 분포를 보이고 있으며, 또한 두개의 모양이 서로 상이함으로 볼 수 있다. 이들의 기능은 주로 기주식물을 탐색하거나 후각기능의 화학적 감각기의 역할을 하는 것으로 추정할 수 있다. 섭식행동이 이루어지는 온실가루이 구기는 전형적인 piercing-sucking type으로, 구침이 길게 잘 발달되어 있다. 구기의 끝부분은 10여개의 미세감각기가 분포고 있어 식물체 표면을 탐색하고 맛을 보는 미각기능을 하고 있으리라 추측할수 있다. 구침은 종종 구기에서 분리되기도 하지만, 구침을 잡아주는 지지대가 기부쪽에 자리하고 있음을 알 수 있다. 구침은 두 개의 반원형이 붙어 있는 형상을 하고 있으며, 다른 흡즙형 구침과는 달리 톱날모양의 구조를 볼 수 없었다. 한편 온실가루이의 다리 끝에 붙어 있는 발톱은 식물체에 고정시키기 위한 구조로 보이는 두 개의 갈고리 형태의 발톱과 그 사이에 중앙지지대 형태의 구조인 paranychium을 포함하여 3갈래의 구조를 하고 있다. External morphology characteristics of the greenhouse whitefly, Trialeurodes vaporarium were investigated by scanning electron microscopy. The antennae of the greenhouse whitefly was 6 segments, rod-shape, and 0.3mm length. On the 6th segment, there were many sensilla for searching host-plant as olfactory receptor. The mouthpart of the greenhouse whitefly was a piercing-sucing type, then its stylet was well developed for piercing plant leaf tissue. Claw of the foreleg was a 3-war hook shape including paranychium for attaching plant surface to pierce and lay egg.

서미영,황현식 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.4

본 연구는 브라켓 간접부착술식시 치면과 레진 베이스의 간격 및 접착제에 따른 전단결합강도를 비교함으로써 브라켓 간접부착의 접착제로서 호제(paste)형 레진 병용의 타당성 여부를 평가해보고자 시행되었다. 소의 하악 중절치 120개를 실험재료로 하여 대조군의 경우 접착제로 실런트만을 사용하는 반면 실험군의 경우 실런트와 호제형 레진을 병용하여, 치면과 레진 베이스 간의 간격이 0.0, 0.2, 또는 0.4 mm가 되도록 접착한 다음 만능물성 시험기를 이용하여 각 시편의 전단결합강도를 측정하고 비교하여 다음의 결과를 얻었다. 1.치면과 레진 베이스 간의 간격이 멀어질수록 두 군 모두에서 전단결합강도가 감소하는 것으로 나타났다. 2.치면과 레진 베이스 간의 간격이 0.0 mm인 경우 양 군 간의 전단결합강도의 차이는 나타나지 않았다. 3.치면과 레진 베이스 간의 간격이 0.2, 0.4 mm인 경우 실런트와 함께 호제형 레진을 병용한 경우의 전단결합강도가 실런트만 사용한 경우에 비하여 통계적으로 유의하게 높게 나타났다. 이상의 연구결과는 브라켓 간접부착술식시 치면과 레진 베이스 간의 간격이 의심될 경우 브라켓 간접부착의 접착제로서 실런트만 단독 사용하는 것보다 호제형 레진을 병용하는 것이 유리함을 시사하였다. (주요 단어 : 간접부착술식, 전단결합강도, 레진베이스, 접착제) The purpose of this study was to evaluate the feasibility of the combined use of paste resin with sealant as an adhesive of the indirect bonding. The resin bases made of light-cured resin were bonded to the bovine incisors at a distance of 0.0, 0.2 or 0.4 mm using the sealant only or the mixture of sealant and paste resin. Bond strength of each group was measured using universal testing machine. The results were as follows : 1.The bond strength was reduced in both groups as the distance between enamel surface and resin base increased. 2.The bond strength showed no statistical difference between two groups in case the distance between enamel surface and resin base was 0.0 mm. 3.In case the distance between enamel surface and resin base was 0.2 or 0.4 mm, the sealant with paste resin group showed significantly higher bond strength than the sealant only group. The results of the present study indicate that the use of paste resin with sealant may be desirable as an adhesive in indirect bonding, particularly in case a gap is suspected between enamel surface and resin base. ※Key words : Indirect bonding, Bond strength, Adhesive, Resin base
