배동한,신영우,조태승 순천향대학교 1989 논문집 Vol.12 No.1

Cis-platinum is a chemotherapeutic agent using in the field of gynecologic malignancy, that can cause severe gastrointestinal disturbances in nearly all patients. Persistent anorexia, nausea, and vomiting may continue for days after chemotherapy and are poorly controlled by conventional antiemetics. Nine patients receiving systemic chemotherapy(PAC protocol) were analysed in a prospective study after administration of three Regimens.(Ⅰ.Ⅱ.Ⅲ) at Obstetrics & Gynecologic department of Soonchunhyang University Chun-an Hospital from Mar. 1986 to Feb. 1987. Patients receiving the combination of methyl-prednisolone and metoclopramide had better relief from vomiting than patients receiving methylprednisolone alone or metoclopramide alone(P<0.05). The results of this study suggest that the combination Regimen of methylprednisolone and metoc- lop- ramide is more effective in controlling Cis-platinum induced emesis.

이차 우식은 수복 실패의 주된 원인 중 하나로 지목되고 있으며, 이로 인해 빈번히 재수복을 하게 된다. 이차 우식은 항우식 작용이 있는 불소를 함유한 수복물을 사용하여 예방될 수 있다. 구강내에서 불소를 유리하는 것으로 알려진 글라스 아이오노머 수복재는 불소를 장기간 유리할 뿐 아니라 불소의 재충전 및 재유리 능력이 있어 불소의 저장소 역할을 할 수 있다. 따라서 본 연구는 통상의 글라스 아이오노머와 고점도 글라스 아이오노머 및 복합 레진을 대상으로 불소의 유리 양상과 불소도포를 통한 재흡수 후 유리 양상을 알아봄으로써 기존의 수복재와 새로운 수복재간의 임상적 유용성을 평가할 목적으로 시행하였다. 4종의 수복재를 대상으로 불소 유리량 및 2% NaF로 재충전 후 불소 유리량을 각각 측정하여 다음과 같은 결과를 얻었다. 1. 실험 대상의 모든 글라스 아이오노머 수복재는 초기에 다량의 불소를 유리하고 이후 점차 감소하는 경향을 보였다. 2. 2% NaF 용액을 통한 재충전 후의 유리량은 Fuji IX, Ketac Fil, Ketac Molar, Z-100의 순으로 나타났다. 3. Fuji IX을 제외한 모든 실험 대상의 수복재에서 수분의 영향으로 표면 경도는 유의하게 감소하였고 불소 재충전 후 유리량은 수분 흡수와 비례하였다(P<0.05). 4. Fuji IX이 초기 유리량에 비해 재충전 후 더 많은 불소를 유리였다(P<0.05). The replacement of dental restorations due to secondary caries is a continuing problem in restorative dentistry. The secondary caries can be partly prevented by using fluoride containing dental materials such as glass ionomer cement, which releases and be recharged with fluoride ion acting as a fluoride reservoir. For the purpose of investigating the behaviors of fluoride release and recharge of conventional and high viscosity glass ionomer cements, the experiment was performed on the seven specimens each from 4 kinds of materials; 1 kind of conventional glass ionomer cement, 2 kinds of high viscosity glass ionomer cements and 1 kind of composite resin. The amount of fluoride release was measured over 7 days with pH/ion meter and fluoride specific electrode. After measuring daily fluoride release, the specimens were recharged with 2% NaF solutions for 4 minutes and measured for 3 days with recharging repeated two consecutive times. The results were as follows : 1. Significantly more fluoride was released at first day after recharge in all materials except Z-100. 2. High viscosity glass ionomer cements released more or nearly equal amount of fluoride after recharge compared with the initial release(P<0.05). 3. The fluoride release after recharge with 2% NaF solution was in order of Fuji IX, Ketac Fil, Ketac Molar, Z-100.

Two cases of verminous arteritis were chosen for this case. These horses were originally submitted for necropsy in the Cheju horse race. Case 1 : At necropy, there was increased ascite, thickened ab-dominal aorta at junction of cranial mesenteric artery. In the aorta, there was a long thrombus embed-ded with strongylus vulgaris larvae. Some larvae were also firmly attached in the aortic intima Histologically, there was infiltration of neutropliils, eosinophils, and macrophages in the tunica media. At the junction of thrombus and arterial intima, there was proliferation of vessels. Case 2 : At necropsy, there was thickened abdominal aorta, which showed typical verminous arteritis with thrombus. Histologically, ceseous tissues with haematopoietic tissue was recognized in the aortic wall.

제 2유구치 기성금관 수복에 따른 제 1대구치의 의원성 손상

배익현,정태성,김신 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.2

소아치과 임상에서 기성금관 수복은 광범위한 우식병소를 가졌거나 치수치료를 받은 치아에 필수적인 술식으로 간주된다. 그러나 기성금관 장착을 위한 치아 삭제 과정 중 인접 치면에 의원성 손상이 생길 경우 우식이환율이 높아질 수 있다. 특히 제 2유구치에 기성금관을 위한 지대치를 형성할 때 인접한 제 1대구치 근심면에 발생될 수 있는 의원성 손상은 치아 우식으로 진행될 잠재성을 가지게 된다. 따라서 본 연구는 제 2유구치의 기성금관을 위한 지대치 형성과정에서 생길 수 있는 제 1대구치의 의원성 손상의 유형과 정도를 알아보고자 하였다. 부산대학교병원에 내원한 소아들을 대상으로 기성금관으로 소복한 제 2유구치의 원심면을 치간이개용 고무링으로 치간이개를 한 후 리버인상재로 인접면의 인상을 채득하고 주사 전자현미경상에서 관찰하여 의원성 손상의 정도를 확인하였다. 제 1대구치의 근심면이 인기된 시편을 주사 전자현미경으로 관찰한 결과, 약 66.7%에서 다양한 유형과 정도의 의원성 손상을 확인할 수 있었다. 따라서 유구치의 기성금관 장착을 위한 지대치 형성과정에서는, 치간이개용 고무링이나 wedge를 이용한 치간이개, matrix band를 이용한 인접 치면의 보호, 인접면 삭제방법의 수정 등과 같은 의원성 손상을 예방하기 위한 술자의 노력이 필요할 것으로 사료되었다. Preformed stainless steel crown is an useful restorative material for the treatment of badly broken down primary teeth. However iatrogenic damage to adjacent teeth might occur during the process of tooth reduction. Such damages might lead to plaque accumulation and increase the risks of caries initiation. Especially the damage can make a problem in the first permanent molar. Purpose of this study was to investigate an iatrogenic damage to the first permanent molar during preparation of second primary molar for preformed stainless steel crown. Twelve children restored with preformed stainless steel crown to second primary molar were selected. Contact areas were separated with separation elastics, and tooth surfaces were cleaned. After taking negative impression using vinylpolysiloxane impression material, the specimens were examined by scanning electron microscope for the detection of iatrogenic damage. The prevalence of iatrogenic damage was 66.7% and variable appearances and So we can suggest that when preparing teeth for preformed stainless steel crown, we should be careful about adjacent teeth not to make an iatrogenic damage.

창의성 및 정보과학적 특성을 기반으로 한 정보영재 판별도구 개발연구

신승용,신수범,배영권,이태욱 한국컴퓨터교육학회 2004 컴퓨터교육학회 논문지 Vol.7 No.4

오늘날 정보화가 빠르게 진행되면서 정보과학의 중요성이 수학, 과학의 중요성 못지않게 대두되고 있기 때문에 이 분야의 영재 역시 조기에 판별하여 교육시켜야 한다는 필요성이 강조되고 있다. 하지만 이에 대한 연구는 초보적인 단계에 머물고 있다. 이에, 본 연구에서는 영재의 판별에 대한 이론적 고찰을 통해서 영재의 특성, 정의 및 판별방법과 도구의 제작과정을 살펴보고 영재의 올바른 판별과정을 조사, 분석하였다. 또한 이를 바탕으로 정보과학의 기반이 되는 이산수학의 특성을 규정하여 이를 바탕으로 정보영재의 특성 및 정의를 내렸으며 이를 근거로 정보영재를 판별할 수 있는 도구를 제작하였다. 판별도구를 이용하여 적용한 결과 판별도구는 신뢰성이 있는 것으로 분석되었으며 향후 정보영재의 의미 있는 판별도구로 활용될 수 있을 수 것이다. Since the science of information is appearing no less important than mathematics and natural science as our society is rapidly becoming information-oriented, the necessity to distinguish prodigies of this field and to educate them as early as possible is also being emphasized. Unfortunately, however, the pertinent study is still in its beginning stage. In this study, I have reviewed the character, definition and method to distinguish prodigies and the procedure of developing a test, as well as researching and analyzing the proper process of distinguishing prodigies, through theoretical contemplation on the method of distinguishing the gifted children. Also, I have characterized and defined the information prodigies after clarifying the character of 'Discrete Mathematics' which becomes the basis of the science of information, paving the way to make a test method that can distinguish those information prodigies. As a result of our applying the system by using the distinction test, it turned out that the distinction test was pretty reliable. Accordingly, it can be utilized as a significant distinction test for information prodigies in the forthcoming future.

팽이 재배에 있어 가장 큰 문제 중의 하나는 雜菌에 대한 汚染, 특히 細菌에 의한 피해가 극심하므로 作業段階와 栽培過程 전반에 걸쳐 培地徵生物相의 經時的인 密度變化에 따른 雜菌의 培地內 流入時期를 조사하여 汚染菌의 發生消長을 알아보기 위해 現地農家에서 시험해 본 결과 接種후 培養室에서 菌絲培養을 시작한 5일후부터 細菌이 檢出되기 시작하여 菌긁기전까지 약 25일간 0.5∼3.1×10⁴cfu/g의 密度를 보였으나 經時的인 密度增加는 없었고, 菌絲培養이 끝난 뒤 菌긁기직후부터 細菌의 密度는 118.3×10⁴cfu/g으로 급격히 높아졌으며 子實體生育 기간동안에 시간이 경과함에 따라 密度가 현저하게 증가되는 경향을 나타냈다. 이는 培養室 안으로 흐르는 空氣를 통하여 甁內로 細菌이 流入되고 또한 菌긁기 직후 培地表面에 灌注하는 물과 加濕機에서 噴霧되는 물粒子가 細菌의 密度增加에 절대적으로 영향을 미치는 것으로 판단되므로 이때가 細菌性褐斑病菌에 感染되기 가장 용이한 시기로 생각된다. 眞菌은 菌긁기후 子實體生育 기간동안 1.17∼7.87×10⁴/g의 密度로서 菌絲培養 기간동안의 密度보다 다소 높게 檢出되었으나 대체로 經時的인 密度增加는 보이지 않았으며, 放線菌은 거의 검출되지 않거나 菌絲培養 후 5일째부터 다소 검출되기 시작했으나 밀도가 매우 낮았고 經時的으로도 증가되지 않았다. One of the most serious problem on the Enoki mushroom cultivation is the infection by pathogenicitic microorganisns, especially bacterial diseases causing serious economical losses in the mushroom production. It was carried out to find the tendency of the development of mushroom diseases by temporal changes and variation of the densities of media microflora through the cultivation periods and working stages in a mushroom farm. According to the results, several bacteria were detected from the fifth day after the inoculation and incubation of mycelium in the incubation room, and the density of bacterium was 0.5∼3.1×10⁴cfu/g media for 25 days before the inoculum-removing, although there was no increment of the density. Since the inoculum-removing after the spawn run, the density of bacterium was rapidly increased as 118.3×10⁴cfu/g media, and was significantly increased by time during the growth period of fruitbodies. It was hypothesized that it is the most suitable period for the pathogen infection because the bacterium might be introduced by the air in the incubation-room, and the increment of bacterium density might be affected by moisture supplied through watering or humidifier in the growing room after the inoculum-removing. Fungi were detected as the density as 1.17∼7.87×10⁴/g media and the density was slightly higher than that during the incubation period of hyphae, although there was no significant increment. Generally, the density of Actinomycetes was disregardfully low, or Actinomycetes were hardly ever found, although there was found some 5 days after incubation hyphae in few cases.

모성 직업활동이 조산, 저체중 출생아 및 자연유산에 미치는 영향을 알아보기 위해 1991년 1월부터 1992년 12월까지 대전에 위치한 C대학병원에서 출생한 1,646명의 산모를 대상으로 하여 조사한 결과는 다음과 같다. 1. 조사 대상자 1,646명의 산모중 임신중 직업을 가진 군이 20.3%, 직업을 갖지않은 군이 79.7%였으며, 직업여부의 분포에 통계적으로 유의한 차이를 보인 변수는 산모의 연령, 교육정도, 임신전 체중, 신장, 유산횟수였다. 2. 임신중 직업을 가진군의 평균 임신기관과 조산율은 39.1주, 7.8%였고, 비직업군은 39.0주, 9.7%였다. 직업군에서 평균 출산아 체중과 저체중 출생아율은 3.228g, 5.4%였고 비직업군은 3,140g, 10.6%였으며, 통계적으로 유의한 차이를 보였다(p<0.05). 평균 자연유산 횟수와 자연유산 경험율은 직업군이 0.2회, 15.0%, 비직업군이 0.3회, 17.4%였다. 3. 연령이 35세 이상, 미숙아 출산력이 있는 경우 및 유산횟수가 2회 이상인 경우는 직업군의 조산율과 저체중 출생아율이 비직업군에 비해 높았으나 통계적 유의성은 없었다. 산과적 합병증이 없는 경우 조산율이 직업군에서 비직업군보다 높았으나 역시 통계적 유의성은 없었다. 4. 자연유산 경험률은 연령이 35세 이상, 학력이 중졸 이하 및 고졸, 산모의 신장이 163cm이상에서 직업군에서 비직업군보다 높게 나타났으나, 통계적 유의성은 없었다. 5. 조산과 관련성이 있는 요인의 영향을 고려했을 때 직장활동군에서 조산의 위험도가 낮았으나 통계적 유의성은 없었다. 6. 임신주수 및 저체중 출생에 관련이 있는 요인의 영향을 고려한 후 직업군에서 저체중 출산의 위험도가 낮았으며 통계적 유의성을 보였다(p<0.05). 7. 과거 유산에 관련이 있는 요인의 영향을 고려한 경우 직업군에서 유산경험율이 낮았으나 통계적 유의성은 없었다. 8. 직업이 교사, 의료인, 은행원, 공무원인 군은 비직업군보다 조산율과 저체중 출생아율이 낮았으며, 회사원은 비직업군에 비해 조산율은 낮았으나 저체중 출생아율은 높았다. 상업군은 조산율과 저체중 출생아율이 15.2%로 비직업군 및 다른 직업군보다 비교적 높았다. 유산경험율은 은행원, 의료인,공무원에서는 비직업군의 17.0%보다 낮았으나, 교사군과 회사원은 17.8, 17.9%로 높았고, 상업군은 33.3%로 다른 직업군에 비해 현저히 높았으며 비직업군에 비해 교차비가 1.42로 통계적 유의성이 있었다(p<0.05). To investigate the effect of maternal job activity on the preterm delivery, low birth weight infant and spontaneous abortion, 1646 delivery data were analyzed from Jan. 1991 to Dec. 1992 in Chungnam University Hospital. The results obtained were as follows; 1. The percentage of subjects who had job during pregnancy was 20.3% and the variables of maternal age, education level, prepregnancy weight, maternal height, number of abotion showed significant difference in the distribution of subjects whether they had job or not. 2. There were no significant difference between the group who had job during pregnancy and those who had no job in the mean gestational period, number of spontaneous abortion, rate of preterm delivery and spontaneous abortion. However mean birth weight and rate of low birth weight showed significant difference between the groups. 3. The rate of preterm delivery of the group who had job were higher than those who had no job activity in the subgroup of 35 years or more age, prematurity history presence, 2 or more abortion history, obstetric complication presence, but there were no significant difference. The rate of low birth weight also higher in the group who had job than those who had no job activity in the same subgroup except obstetric complication presence. 4. The rate of spontaneous abortion of the group who had job were higher than those who had no job activity in the subgroup of 35 years or more age, below high school, height of 163cm or above, but there were no significant difference. 5. Rate of preterm delivery still showed better results in the group who had job than the group who had no job when adjusted for variables related, but there was no statistical significance. 6. Rate of low birth weight still showed better results with statistical significance in the group who had job than the group who had no job when adjusted for variables related. 7. Spontaneous abortion had occured less frequently in the group who had job than the group who had no job when adjusted for variables related. 8. Rate of preterm delivery and low birth weight were lower in the group of teacher, bank clerk, medical personnel, citizen servant than the group who had no job, but higher in the job of company employee, commerce. Spontaneous abortion was most frequent in group of commerce, and the group of teacher, company employee showed higher rate of abortion than the group who had no job.
