Objective : Our purpose of this study was to determine the clarity and consuming time of fetal surface screening in thirty-eight fetuses from 24 to 32 weeks of gestation by use of two and three-dimensional ultrasonography. Methods : From May 1998 to July 1998, we performed the fetal surface screening of the fetal face, extremities, and spine. Thirty-eight fetuses of 24-32 weeks of gestation (thirty-seven normal fetuses and one abnormal fetus) were studied by use two-dimensional (AI 5200S, 3.5-5.0MHz; Acoustic Imaging Technologic Cooperation, U.S.A.) and three-dimensional ultrasonography (Volusion 530D, 3.5-5.0 MHz ; Kretz-Medicine, Korea). On the fetal face, we evaluated both orbits, nose, lips and brow. Both hands and feet, five digits and toes should be seen in this study. We evaluated cervical spine and lumbosacral junction of the spine. Results : The maternal average age of 38 patients was 29.9 years and the average gestational age was 29.7 weeks. The results of fetal surface screening were as follows : face (both orbits 89.5%, lips 92.1%, nose 92.1%, and brow 89.5%), extremities (both hands 68.4% and feet 73.7%), and spine (cervical spine 94.7% and lumbosacral junction 97.4%) by use of two-dimensional ultrasonography. By use of three-dimensional ultrasonography, results were as follows : face (both orbits 76.3%, lips 81.6%, nose 81.6%, and brow 78.9%), extremities (both hands 76.3% and feet 78.9%), and spine (cervical spine 71.1% and lumbosacral junction 73.7%). Consuming time for two-dimensional ultrasonography were 4.7 minutes for face, 11.6 minutes for extremities, and 5.7 minutes for spine. Using three-dimensional ultrasonography results were 12.8 minutes for face, 17.9 minutes for extremities, and 11.7 minutes for spine. Average consuming time of all fetal anatomic screening was 22.0 and 42.4 minutes by use of two and three dimensional ultrasonography. In one abnormal fetus had cleft lip and polydactyly of right foot which were detected all by three-dimensional ultrasonography, but we couldn't detect the polydactyly by two-dimensional ultrasonography. Conclusion : Three-dimensional ultrasonography was more time-consuming method, but we suggested that three-dimensional ultrasonography was superior than two-dimensional ultrasonography in fetal surface screening.

The dose-response effect of polysaccharide extracts(PS-1) from Artemisia iwayomogi was investigated under various hepatic disease models. Silymarin, DDB and UDCA were used as reference compounds. We found that the maximal effective dose of PS-1 was 100 ㎎/㎏ b.wt. in CCl_4-induced hepatotoxicity, D-galactosamine-induced hepatitis, in ANIT-induced cholestasis and 300 ㎎/㎏ b.wt. in CCl_4-induced chronic liver disease, 30 ㎎/㎏ b.wt. in chronic bile duct ligation and chronic ethanol fatty liver. These findings suggest that PS-1 fraction protects the hepatocyte against various hepatic injuries, and this fracton might be of therapeutic value.

이윤호,김순석 동국대학교 사회과학연구원 2008 사회과학연구 Vol.14 No.2

Understanding the adaption of prison inmates to prison life is one of critically important concerns for correctional administration. Correctional administration not involving such the concern is widely viewed as one having significant limitations in helping prison inmates to get re-socialized. In this context, this study was performed with 320 subjects who were adult male and female convicts with one or more criminal records of imprisonment, confined in prison across the country. The studied variables included: importation factors such as gender, age, educational background, marriage, the presence of offspring(s) and cumulative criminal history, and inmate-family intimacy related indexes such as correspondence with family members, phone conversation with family members, family visiting, provisional holding by family members, and divorce claim by the spouse. As a result of analysis, the sentence-serving attitudes of inmates in prison depended upon two importation factors: marriage and the presence of offspring(s). In addition, the higher the frequency of correspondence with family members and their visiting to prison was, the better their sentence-serving attitudes were. In conclusion, for the sake of more effective and desirable correctional administration, it is required to develop a variety of programs designed to strengthen social ties, especially family ties with inmates, and consequently, to encourage their desire for rehabilitation and recidivism control, in the manner of analyzing thoroughly the importation factors of prison inmates to individualize the practices of correctional administration. 수용자들의 교도소 내 생활 적응을 파악하는 일은 교정행정이 가져야하는 주요 관심사이다. 이런 관심이 무시된 교정행정은 수용자들의 재사회화를 실현시키기 어렵다는 것이 일반적 견해이다. 이 연구는 이러한 목적 하에서 전국 교도소에 수용되어 있는 실형전과 1회 이상의 성인 남녀 기결수 320명을 대상으로 실시되었다. 연구에 포함된 변인들은 유입요인에 해당하는 성별, 연령, 학력, 결혼여부, 자녀유무, 누적전과와 수용자와 가족간의 친밀도를 나타내주는 가족과의 서신교환, 가족과의 전화통화, 가족의 면회, 가족의 영치, 배우자의 이혼요구 등이 포함되었다. 분석결과 수용자들의 교도소내 수형태도는 유입요인 중 결혼여부 및 자녀유무에 따라 다르게 나타났으며, 또한 가족과의 서신교환 및 면회 등과 같은 접촉이 많을수록 수형태도도 양호한 것으로 나타났다. 결론적으로 교정행정이 관심을 가져야 하는 부분은 수용자의 유입요인들을 철저히 분석하여 개개인에게 맞는 맞춤형 교정과 더불어 수용자들이 사회적 유대, 그중 가족간의 유대를 결속시키고 이를 통해 사회복귀와 재범 억제의 욕구를 강화시킬 수 있는 다양한 프로그램들을 개발하여야 할 것이다.

The purpose of this study is to examine the concept, objective, content and preceding researches of peace educations, and to review the historical changes and the prospects for the early childhood peace educations. First, early childhood peace education has the conceptual objective of achieving eternal peace of humanity, with the basic principle of having children understand relationship, cooperation, dispute resolution and violence, to enhance a child's self-efficacy feeling. Second, the purpose of early childhood peace education is to nurture inquisitive minds, learn knowledge and technique, increase respect for humanity and religions, broaden understanding of the world, or learn knowledge, technique and attitude of peace education. Third, transition of early childhood peace education through our country's preceding researches of peace education is changing from concept and philosophy to practical application program development. Fourth, early childhood peace education's historical change is begin from ancient times' Plato to Comenius, Rousseau, Pestalozzi, Froebel, the UNESCO's Charter, a critical peace education thought, and come to modern changing from passitive concept anti-war, anti-nuclear to active concept through social bonds and behavior not individual dimension. According to above the prospects for early childhood peace education is peace education in human beings' the greatest subject emphasis must begin from early childhood in important period of life.

수락계곡에 있어서 산록시면 하부의 이치림의 군락구조에 대한 속성을 조사한 결과 다음과 같이 요약할 수 있다. 1. 본 군락은 54종의 식생으로 구성되었는데 교목층은 참나무류가 우점하고 있으며, 아교목층 저목층으로 내려갈수록 서어나무 신갈나무의 중요치가 높아지고, 초본층에서도 서어나무 물푸레나무 치묘가 많이 발생하고 있으므로 굴참나무가 우점하는 군락에서 신갈나무, 서어나무 군락으로 천이 cycle이 진행중인 것으로 판단된다. 2. 군락전체의 종다양도는 1.5452로 높았으나, 교목층의 종다양도는 낮았고, 종내경쟁이 심하였으며, 종간경쟁은 초본층이 가장 심하였다. 또한 저목층에서 안정도가 가장 높게 나타났으며, nich breadth는 초본층이 가장 높게 나타나는 것을 볼 때 초본층에서 교목층까지 차례로 생태적 지위가 재편성되는 과정으로 판단된다. 3. 수고 분포도와 흉고직경급 분포도를 토대로 군락동태를 예측해본 결과 천이 초기종인 굴참나무, 갈참나무가 교목층에 우점하는 군락에서, 천이 후기종인 신갈나무, 서어나무가 침입하여 천이가 진행중인 군락으로 판단된다. This research was aimed at figuring out the characteristics of community structre of secondary forest ecotone of deciduous broad leaved trees in foot slope of Wolsobong area, Which valley and foot slope and hill side doing net crossed. It can be expected to provide the fundamental data for tending and natural regeneration of broad leaved forest, in the Mt. Daedun as being known as temperature middle zone. The results are such as follows: The vegetation of the secondary forest ecotone, which foot slpoe and hill side being crossed, was composed of 54 species, the canopy domineted species, Quercus spp., for example. And under story, shurb layer was going lower, dominance species were Carpinus laxiflora, Quercus monglica. So it might be said that the investigated area is doing succession at the present time. Species diversity appeared 1.5452 at high values. Therefore the investigated area is reflecting species composition by environmental factors. On the other hand, at the each layer level, species diversity of the upper layer was lower values and interspecific encounter of herb layer the highest. And it may be concluded that niche breadth does appeared reforming, due to the stability of shurb layer strong of intraspecific encounter. Through analyzing dynamics of the community with using data, height distribution and D.B.H. class distribution range, Quercus variabilis, Quercus aliena species were rapidly growing well adapting. Afterwards it is assessed that the community structure of researched area will be obviously devoloped climax such as dominated Quercus monglica or Carpinus laxiflora community.

We reviewed 10 years experiences of the clinical aspects and early postoperative results in 544 pediatric patients(age less than 16 years old). Among them. 529 cases had the congenital heart diseases, and 15 had the acquired diseases. Open heart surgery was performed in 413 patients. 115 cases were treated with non-open heart surgery. 16 with interventional catheterization. Annual increase of the cardiac patients was not significant in recent 10 years, except slight increase in 1994. The mean age of the study patients had been evidently changed to younger year by year. Total mortality rate of the open heart surgery was 6.4%. The cyanotic congenital heart diseases were high in early postoperative mortality by 25.7%, whereas 4% in acyanotic group. The age group less than one month was most highest in surgical mortality(66.7%). There were no deaths in patients with patent ductus arteriosus(103 cases), atrial septal defect(83 cases) or pulmonary stenosis(17 cases). Among 220 patients with ventricular septal defects(VSD). 10(4.5%) were died early postoperatively. In cyanotic group, the patients with pulmonary atresia with ventricular septal defects(PAVSD), transposition of the great arteries(TGA), interrupted aortic arch(IAA), complex cardiac anomalies with isomerism seemed to be most susceptible to an early death.

Risk Factors for Posttraumatic Seizure The authors evaluate the risk factors for posttraumatic seizures. this prospective study was performed in a series of 470 head injured patient from January 1996 to Decomber 1998. The patients who were dead within 1 week of injury or children from 3 years old and under were excluded. There were 358 male and 112 female with a mean age of 35.2±22.8 years (range, 4-88 years). The results were as follows : 1). Of the 470 patients, pasttraumatic seizure occurred in 48 patients(10.2%): early seizure in 28(6%) and late seizure in 20 patients(4.2%). 2). The clinical risk factors for posttraumatic seizure were poor consciousness at admission, presence of brainstem herniation signs, poor GCS score, and posttraumatic amnesia more than 24 hours after trauma(p<0.001). 3). The radiological risk factors for posttraumatic seizure were subdural hematoma(p<0.001), intracerebral hematoma (p<0.02), mutiple intracranial CT lesions(p<0.001), or delayed lesions on follow-up CT scans(p<0.001). the incidence of seizure increased according to the severity of diffuse brain lesion(p<0.001), and the seizure rate in mass lesion was higher than that in diffuse lesion(p<0.001). 5). Hypoxia and coagulopathy had a statistically significant influence on posttraumatic seizure(p<0.05). Hypoxia had a infuence on occurrence of late seizure(p<0.05). 6). The incidence of posttraumatic seizure signiticantly increased in surgical group compared with coservative group(p<0.001) and significantly increased in patient who underwent decompressive craniectomy compared with those who underwent craniotomy(p<0.001) 7). Preventive administration of antiepileptic drugs decreased the incidence of early seizure, but did not affect on the reduction of late seizure. 8). Multivariate logistic regression analysis showed the subdural hematoma, GCS score, delayed lesion, and intracerebral hematoma in order of importance for seizure risk. in conclusion, the risk factors affecting on the occurrence of seizure were clinical status at admission, CT lesions, and severity of diffuse brain inJury. Considering that hypoxia affected on the late seizure, it is necessary to detect and treat it immediately after trauma. In addition, the patients who underwent decompressive craniectomy should be carefully followed to evaluate the risk of late seizure. Even though preventive administration of antiepileptic drugs had a tendency to decrease the incidence of early seizure, it is unclear whether administration of antiepileptic drugs can reduce the incidence of posttraumatic seizures. Prospective study will be needed in the selected patients.
