최명호,이주희,박명진,고영철,김남철 국립7개대학공동논문집간행위원회 2001 공업기술연구 Vol.1 No.-

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.

지역 청소년 정신건강 교육을 위한 기질에 따른 도형선호도 분석에 관한 연구

우명철(Woo, Myung-chul) 한국여가복지학회 2021 여가복지경영연구(여가복지) Vol.2 No.1

이 시대의 청소년들의 학업부진, 정서, 불안정성, 우울감, 우울증, 불면증, 편집증, 무감각, 노여움, 두려움, 공포, 학교폭력, 및 자살 등의 문제에 직면하고 있으며 현대인들의 복잡한 생활양식인 인관관계의 몰이해에서 오는 정신적인 문제들이 빈발하고 있는 이 때 현대인들의 정신건강 관리를 위해 다양한 프로그램 중 치유상담을 병행할 수 있는 도형을 통한 상담 및 도형상담, 우쓰치유학은 편안하게 접근하여 정신적인 내면과 영적상태를 파악 치유할 수 있는 효율적인 진인치유 기법이며 통계 과학적인 상담기법의 도구가 될 것이다. 우쓰도형기질유형 척도 개발 연구를 위해 상담분야인 현존하는 두 이론, 수잔 델린저 도형이론과 팀 라헤이 기질이론을 이용하여 본 연구자는 우쓰힐링상담연구소에서 상담의 정확성과 효율성을 높이고자 연구하였다. Woo s Healing 진단 유형인 심리상담의 도구 척도를 활용을 하고자 척도를 보안하고 요인분석과 상관관계를 가설로 정하고 분석하였다. 조사기간은 90일간, 142명을 실증적인 상담을 겸하여 조사하였으며 본 척도를 분석하기 위해 spss 24.0을 이용하여 요인분석 프로그램을 이용하여 타당성을 분석하였다. 본 척도는 사각형기질 2성분, 8개, 원형기질 4성분, 9개, 사각형기질 1성분, 9개, S기질 3성분, 8개, 문항을 추출하였다. 검사지 한 장속에 도형을 그리게 하여 그 속에서 도형의 형태, 위치, 크기, 작기, 배열을 통해서 심리상태, 정서적인 면과 무의식 속에 있는 과거의 심리적인 상처들과 견고한 진들을 발견하게 하여 현재를 발견하고 미래를 제시하며 편안하게 접근하여 정서적인 안정성을 갖게 한다. 도형을 통한 심리학적 상담인 우쓰치유학은 영성이 없이는 내담자를 통찰하기 어려우며 영성도, 심리학이 없이는 우리의 가면의 문제를 해결할 수 없듯이, 어찌 보면 우쓰치유학은 심리학과 영성사이의 가교역할을 할 수 있다고 볼 수 있으며 이는 어느 누구 계층의 사람도 편안하게 접근하여 간단하면서도 빠르게 진단하는 전인치유적인 상담기법으로 이끌어 내는 통계 과학적인 학문으로 이는 우쓰치유상담기법이다. A Study On The Development Of Woo s Geometric shape Temperament Type Indicator Woo Myung-cheol CEO, Woo s Educational Research Institute for Healing & Counseling Purpose; In the Modern Era, Science and Medicine are developed nutrition and sanitation conditions very much are improved. But Human Happiness is not progress, Frankly Saying, keeps on worseing. Youth do not know their way that leads them true happiness. Modern Men contain Youth are suffered and stressed by Pollution with Political and Econimic Situations. In order to resolve these hard situations, We are to use and develop further Mental Therapeutic Curing as well as Woo s Healing Woo s Geometric Shape. Psycho-geometrics. And We are to contain Whole Man Healing or Holistic Therapy to Care Contemporary Men. Methodology ; Mental or Spiritual Healing for Modern Men needs Various Programscontain Woo s Healing and Psycho-geometrics using Woo s Geometric Shape and Temperament Type. Especially Woo s Healing contributes emotional, mental, spiritual healing using scientific counseling method, effetive statistial analysis, and contact them comfotablely. Findings; These experiment found out that Temperament Types are deep meaningly relative one another. Results ; We make the best use of Using these Findings to develop human relation with our neibourhood and mental, spiritual peace privately.

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.

Objective: The aim of this study was to investigate the clinical charact eristics of pregnancy induced hypertension(PIH). Methods: We retrospectively evaluated the clinical characteristics through the collected data of 176 PIH cases treated at Seoul Paik hospital from March 1995 to December 2002. Results: The proportions of severe PIH, mild PIH, and chronic hypertension were 70%, 24%, and 6% of the cases, respectively. According to maternal age, the highest rate of 45% was noted in the group of 26-30 years of age. The rate of cesarean(80%) was higher than the rate of vaginal delivery(20%). The blood pressure was controlled by hydralazine for 70% of the patients. The rate of single gestation was 90%. The birthweight of 20% of the newborn were 2500gm or more. The anemia, twin pregnancy, postpartum hemorrhage, pulmonary edema, and infection were found in 30%, 10%, 3%, 2%, and 1% of the PIH patients, respectively. In respect of the perinatal complications, the rates of low birth weight, stillbirth, and neonatal death were 80%, 3%, and 1%, respectively. Conclusion: We were able to decrease the mortality and morbidity of PIH patients and neonates with strict antenatal care and proper treatment.

두경부 악성 종양에 대한 방사선치료는 유용한 방법이다. 하지만 방사선치료의 부작용으로 다양한 구강내 합병증을 동반한다. 이 글에서 치열 발육 단계에 방사선치료를 받은 두 증례를 보고하는 바이다. 첫 번째 증례는 생후 19개월에 급성 골수성 백혈병으로 진단 받아 방사선치료를 받은 7세 여자 환아로 영구치 치배의 선천적 결손과 왜소치 소견을 보였다. 두 번째 증례에서는 생후 13개월에 양측성 망막아세포종으로 진단 받아 방사선치료를 받았고 영구치 치배의 선천적 결손, 왜소치, 치근의 저형성 그리고 법랑질 저형성증 소견을 보였다. Radiotherapy for head and neck tumors is a viable treatment modality. However, a wide range of potentially debilitating dental complications may be accompanied by this treatment. We report two cases of developmental disturbance of permanent tooth germs after radiotherapy. The one was that of a seven-year-old girl, who had congenitally missing teeth, and microdontia of permanent tooth germs. she had received radiotherapy for acute myelocytic leukemia at the age of 19 months. The other was that of a nine-year-old boy, in which congenitally missing teeth, microdontia, root hypoplasia, and enamel hypoplasia of permanent teeth were observed. He had undergone a course of radiotherapy for bilateral retinoblastoma at the age of 13 months.
