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.

Objectives: This study was conducted with new workers who entered lead industries from 1992 to 2001 to evaluate the genetic susceptibility of ALAD (δ-aminolevulinic acid dehydratase) and VDR (vitamin D receptor) gene on health effect of lead exposure. Methods: Among the subjects of the database of lead industries at the Soonchunhyang University Institute of Industrial Medicine, only new workers were selected for this study. The total of eligible workers for this category was 3,540 workers, including non lead exposed workers of same lead industries. From stored blood in specimen bank of Soonchunhyang University, genotype of ALAD and VDR were measured using PCR method. Variables for this study were blood lead as an index of lead exposure, ZPP (zinc protoporphyrin in blood), urine ALA (δ-aminolevulinic acid), and hemoglobin as an index of hematopoietic effect of lead. Information on sex, job duration, and weight were collected for personal information. The data were analyzed using SAS (version 8.2) with descriptive analysis of t-test and multiple regression analysis. Results: Among 3,540 new employed study subjects during period of 1992-2001, 3,204 workers (90.5%) had ALAD genotype 1-1, while 336 workers (9.5%) had variant type of ALAD (1-2 or 2-2). For VDR genotype, 2,903 workers (89.7%) out of total tested 3,238 workers were belonged to type bb and 335 workers (10.5%) were type bB or BB. The distribution of genotype of ALAD and VDR were not different according to the job duration in male workers, but were different in female workers. The effect of ALAD and VDR genotype on blood lead were positively significant in the analysis of all cumulative data of new employed workers for 10 years. The effect of VDR genotype on blood lead were stronger than that of ALAD While the variant ALAD gene made decrease of mean ZPP and ALA in urine after controlling for blood lead and other covariate, the variant VDR gene made increased the mean ZPP and ALA in urine in all cumulative data analysis and cross sectional analysis by job duration. For hemoglobin, ALAD and VDR genotype did not affect the mean value. Conclusions: From the above our results, we found that ALAD and VDR genotype exerted significant effect in various way. We confirmed that the finding of a cross sectional study of protective effect of variant ALAD on the effect blood lead on blood ZPP in our retrospective study design. It was found that VDR did not exert protective effect for lead exposure as the variant ALAD did.

고상반응법으로 SrCl_2:Eu^2+ 형광체를 제작하고, 제작한 형광체의 광자극발광과 광발광 특성을 조사하였다. SrCl_2:Eu^2+ 형광체와 광발광 및 광자극발광은 Eu^2+ 의 5d->4f 천이에 기인되었으며, 355 nm의 광으로 여기시켰을 때 광자극발광과 광발광 스펙트럼의 파장범위는 모두 380~440nm이었고, 피이크 파장은 407nm이었다. SrCl_2:Eu^2+형광체의 선량의존성은 2.5 mGy~200mGy영역에서 우수한 선형성을 나타내었으며, 상온에서 광자극발광의 fading은 20분에 60%이었다. SrCl_2:Eu^2+ phosphors were prepared by the solid phase reaction method, and their photostimulated luminescence(PSL) and photoluminescence(PL) characteristics were investigated. The PSL and PL peak of the SrCl_2:Eu^2+ phosphors are due to the 5d->4f transition of Eu^2+ ions in phosphors. The PSL and PL spectrum obtained by the 355 nm exitation was observed in 380~440 nm region with the peak at 407 nm. The dose response of the PSL phosphors were linear within 2.5 mGy ~ 200 mGy of 100kV X-ray. The fading of the phosphors at room temperature was approximately 60% after 20 min.

Objectives : We report an interim result of conformal radiotherapy in a patient with early stage cancer at the base of the tongue, which developed in a previously irradiated area. Materials and Methods : A 64-year-old male patient was diagnosed with T4NOMO supraglottic cancer. He received 72Gy of radiation therapy from 21 November 1988 to 24 February 1989. He had local failure and underwent a salvage total laryngectomy on 28 August 1989. Subsequently, he did well. In early 1999, he suffered from throat pain. He had a 2.5cm ulcerative mass at the base of his tongue, in the area that had been irradiated previously. Biopsy showed squamous cell carcinoma. After workup, he was diagnosed with base of tongue cancer with T2NOMO. Surgery was not feasible because the morbidity was not acceptable. Since it was difficult to re-irradiate the area with a curable dose using conventional 2D radiation therapy with an acceptable morbidity, we decided to try conformal radiotherapy. We used 7 static beam ports with field sizes from 7×6.4 to 8×8㎠, using 6 and 10MV photons. The fractionation regimen was 1.8Gy, 5 times per week. He received 64.8Gy in 36 fractions from 9 April 1999 to 1 June 1999. Results : In the 21 months since radiotherapy, the patient has not experienced any acute or chronic complications, such as xerostomia. He experienced relief of pain shortly after the start of radiotherapy, showed a complete response, and is still doing well. Conclusion : Conformal radiotherapy can be used to treat cancer that develops within a previously irradiated field, with curative intent.

For the purpose of obtaining basic information for the implementation of occupational Health service for woman workers, the knowledge and attitude questionnaire study was carried out on 587 woman workers who were working in textile, machinery, chemical and other industries in Chunan area. The results of this study were as follows: 1. While more than 50% of woman workers in textile machinery and chemical industries worked 44 hours per week, higher proportion woman workers in other industries worked more than 48 hours per week. 2. The joining rate of trade union of workers was 68.5%, but the active participation rate was low regardless of type of industries. 3. While 48% of workers in textile industries thought their health as good condition only 29.3% of workers in chemical industries thought their health as good one. The rate of women in good health was higher in workers whose age were under 30 than those over 30. 4. While 55.2% of total workers answered their working conditions as normal, only 17.9% of workers did that their working condition were in good and bad condition. 5. Television was the most important source of information for occupational disease and hearing from colleague was next important source. On the other hand, 20.6% of workers answered that they never hear the word “occupational disease”. 6. While 53.7% of workers thought that improvement of working condition is the most important method for the prevention of occupational disease and 13.4% or workers thought that annual health examination is the most. On the other hand on 2.4% of workers thought that there was no method to prevent occupational diseases.

매스ㆍ미디어에 의한 프라이버시 침해에 관한 연구

金炳國 圓光大學校 1983 論文集 Vol.17 No.1

This article discusses various aspectsof privacy invasions by mass communication media. A person has a right to be let alone, and mass media hasthe right of free reporting in its own right. If Mass Media invades the right to privacy, the injured person has also a right to seek redress. The harm against which the privacy law guards is injury to plaintiff's personal right to be let alone. So any action that may invade one's personal calmness protected from social intervention makes out privacyassault case. On the other hand, Mass Media has the right of free report under the democractic constitution, but of course it is responsible for abuses of the right, Mass media has to take legal risk, if its report is to invade another person's right of privacy. In the modern society, we are more concerned with protection of oneself. But techon-ological developments take us under the risk of public disclosure at any time, so the need to protect privacy and the debate about it are increased. If it is not public concern or public interest, the law generally prevents full and complete discussion of personal matters. But it is very difficult to lead conclusions between social concerns and private matters. It is very fluid according to personal charactristic, circumstances and cultural backgrounds. Privacy is to be respected as essential parts of human happiness and dignity, but as yet the right to privacy is not firmly established in our country. As our people are not well developed in right-consciousness, the law must act fully symbolic function as defenders of people's right and mass media institutions must constrain themself in ethical view point.
