Sintering characteristics and microwave dielectric properties of the Ba_2Ti_9O_20 ceramics added with lithium-boro-silicate glass frit were investigated. Sintering experiments showed that the densification occurred at lower firing temperatures down to 900℃ as the addition of glass frit was increased up to 10wt%. The bulk density and shrinkage of ceramics were strongly dependent on the amount of the glass frit. The microstructures of the ceramics were found to become skeletal-like structures as increase of glass frit. The monoclinic crystal structure of the Ba_2Ti_9O_20, however, was found not to be affected by the addition of glass frit up to 10wt%. Microwave dielectric constants of the glass frit added ceramics were relatively consistent of 35 with over 15% shrunk and densified ceramics. However, the quality factor (Qf) and the temperature constant (TCP) was found to be significantly affected by the additions of glass frit.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

학교 교육 체제 내의 남녀 불평등 구조와 그 개선에 관한 고찰

金明澈 釜山敎育大學 1991 부산교육대학 논문집 Vol.27 No.1

Keeping pace with recent social reforms in Korea, schooling should also be reformed in various aspects for young people in the 21st century, especially in the aspect of eliminating inequality mechanism between male and female. The present study has focused on finding out effective ways of abolishing sexual inequality mechanism in schooling, which has been deeply influenced by traditional patriarchy and capitalism in our society, on the basis of many kinds of articles and books concerned. 1. Educational ideology, objectives, curriculum and teaching method in school should be decisively reorganized to be fitted with substantial equal opportunity system between male and female on the basis of androgyny theory. 2. Teachers in school and authors of textbooks for students should be innovated in their way of thinking and attitude in favor of sexual equality in school context. 3. Educational law for establishing equal opportunity between male and female should be prepared to be taken effect substantially as well as nominally. 4. Females as a counterpart of males should cultivate good ability to work, leadership, group power to resist against sexual inequality mechanism and even physical power which can be a match for those of males, emerging from traditional passiveness, dependence and weakness, etc.

There has been going on a dispute about the effectiveness of homework. There were a lot of results from studying about it but researchers have been from unanimous. So for the study particularly has been performing about quantity of homework and the time of homework, parental involvement, teacher reinforcement and feedback, attitude, the kinds of homework, the grade level, sex, and so on, but no study on the effect of homework skill on homework performance(homework completion and homework quality) and achievement has been investigated. Before study on it, I felt a need to study about a definition and components of homework. For this study I looked over the study skill and the program of Byun Chang Gin, Kim Seong Hoi, Mun Su Back(1994), Jun Hoa Chun(1998), Kim Eun Ju(1998) developing through an analysis and a synthesis of study skill within and without the country, and various strategies, programs and guides connected with homework, factors influencing the effect of homework, homework style and behavior scale. Through this analysis homework skills was divided into skills for managing school materials, skills for maintaining a home study area, skills for following directions, time management skills, and self―management skills. In future, We need a study to examine that scale development of homework skills, and the extent of that homework skills correlate with the effectiveness of homework, that is homework performance and academic achievement.

Fuel transport was visualized within the cylinder of a port injected four-valve SI engine having a transparent cylinder liner. Measurements were made while motoring at 250rpm to simulate cranking conditions prior to the first firing cycle, and at 750rpm to examine the effects of engine speed. A production GM Quad-4 cylinder head was used, and the stock single-jet port fuel injector was used to inject indolene. A digital camera was used to capture back-lighted images of cylinder wall wetting for open and closed intake valve injection. In addition, two-dimensional planar imaging of Mie scattering from the indolene fuel droplets was used to characterize the fuel droplet distribution as a function of crank angle for open and closed intake valve injection. LDV was used to measure the droplet and air velocities near the intake valves during fuel injection. It was found that with open-valve injection a large fraction of the fuel impinged on the cylinder wall opposite the intake valves. This fuel did not completely vaporize over the engine cycle and built up over successive motored cycles. The small droplets that impinged upon the cylinder wall coalesced quickly due to surface tension forces, which impeded fuel vaporization from the cylinder wall. For closed-valve injection the fuel was stripped from the intake valves and ports very shortly after intake valve opening by the incoming air. There was very little impingement of fuel on the cylinder walls with closed-valve injection, but some fuel droplets apparently impinged on the piston top. It was observed that the droplets from closed-valve injection tend to be larger than those from open-valve injection, although this was not quantified. With closed-valve injection, droplets entering the cylinder had lower velocities than the incoming air. With open-valve injection, the early droplets entering the cylinder had higher velocities than the incoming air, but the droplets and air velocities were very close for most of the injection period.

Abstract This research is to explore the preferences of the freshmen's thought, emotion, and acton and to advise them to live their school lives well. The test instrument is MBTI(Myers-Briggs Type Indicator) which indicates inborn personal preferences of a person. 381 students(male 99, female 298) participated in MBTI. The purposes of this research are as follows; First, to help the freshmen understand themselves more than they did. Second, to help them understand the others more than they did. The last, to help them make good relations with others who are their classmates, professors, and families, etc. The results of this research are as follows; First, a lot of freshmen have the types of ISFJ, ISTJ, ESTJ. Second, every department has its unquit of preference. The suggestions of this research are that there are the necessities of forming group programs by MBTI and enlarging the width of subjects - the whole students, professors, and personals of the university.

In this study, I considered the concept of aggression, the aggressive theory, and the aggression performance relationships in order to see the aggression in sport. I summarized as follows. 1) In the sport, the definition of aggression is the intention to harm another person and according to the intention is divided between hostile aggression and instrumental aggression. 2) In the instinctive theory, sport is the outlet of the aggressive drive. 3) In the frustration-aggression theory, the aggression is induced from frustration and if the aggression is appeared successively, it was cathartic effect. 4) In the social learning theory, the aggression is taught and reinforced through sport. 5) Aggression-performance relationships can't be decided positive or negative, and must be considered the variables such as the eventual specification, the team standing, the sexual difference, and the performance.

성토사면에 적용된 Soil Nailing의 주면마찰특성 연구

이성철,김명학,김상현,윤성학 인제대학교 2001 仁濟論叢 Vol.16 No.1

Soil Nailing 공법은 사면안정을 목적으로 보강재를 사용하여 지반을 보강하는 현장 지반보강 공법의 일종이다. 지금까지는 일반적으로 Soil nailing이 주로 절토사면을 보강하는 기술로 사용되고 연구되어 왔으나 본 논문에서는 붕괴된 사면에 재성토를 시행한 현장에 대한 보강공법으로서의 적용성을 연구하였다. 이를 위하여 네일에 스트레인 게이지를 부착하고 현장인발실험을 수행하여 최대인발하중을 조사하고 각 지층에서 발휘되는 단위 주면마찰력을 산정하였다. 그리고 본 연구에서 얻어진 겉보기 평균 주면마찰력을 일반적인 절토사면에서 현장인발실험을 수행한 다른 사례의 겉보기 평균주면마찰력과 비교분석해 보았다. Soil nailing is in-situ ground improvement technique of reinforcing soils using passive inclusions for the purpose of slope stability. Also soil nailing, in general, was used and studied as a reinforcement technique at cut slope, but this paper presents the results of study for soil nailing application as a reinforcement technique at the banking over slided slope. In-situ pull-out tests of nails, instrumented with strain gauges, were performed to investigate the maximum pull-out load and to calculate the unit side resistance in each different layer, And the apparent average unit side resistance of this study was compared with that of other sites installed at cut slop.

平生敎育의 관점에서 본 學校敎育의 民主化

金明澈 釜山敎育大學 1988 부산교육대학 논문집 Vol.24 No.1

Judging from recent social reforms future society of Korea is predicted to be fully democratized in political, economical, social and cultural aspects. Therefore it is natural and proper that schooling be also democratized and re-organized in keeping pace with social changes. But because of many problems and limits it is very difficult for today's schooling to democratize for itself. The present study has focused on attempting re-organization of schooling into life-long education system on the basis of many kinds of articles and books concerned. 1. Schooling as one of life-long education system should put its primary goal on acquisition of motivation and potentiality which enable students to continue their own education after graduation from school. 2. School curriculum should include a variety of practical subjects related to daily life, and general principles as well as basic conception of each knowledge should be taught in classroom. 3. Teacher-centered teaching method should be substituted for students-centered one like self-directed learning, and self-evaluated system is desirable for their continuous learning. 4. Government and school authorities should legally and substantially support open education system and freer use of school facilities and materials for the benefit of community residents.
