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.

Lead sorption performances by biomass of nonliving, dried marine brown algae Undaria pinnatifida, Hizikia fusiformis, and Sargassum fulvellum used as biosorbent materials were investigated. As the amount of biosorbent materials added was increased, the lead removal by biosorbent materials increased but the lead biosorption capacities decreased. However, with increasing initial lead concentration the lead biosorption capacities by the biosorbent materials increased but lead removal efficiencies decreased. In the range of initial lead concentration(C_0) 10-500 mg/L the lead biosorption capacities and removal efficiencies by the biosorbent materials increased with increasing pH. Among the biosorbent materials used in this study, the lead biosorption capacities decreased in the following sequence: U. pinnatifida $gt; H. fusiformis $gt; S. fulvellum. The lead biosorption by biosorbent materials were expressed by the Langmuir isotherm better than the Freundlich isotherm. The biosorption rate could be expressed by the first order reaction rate equation for initial lead concentration like that r_ad = 0.288C_0 for U. pinnatifida, r_ad = 0.255C_0 for H. fusiformis, and r_ad = 0.161C_0 for S. fulvellum.

강원도는 오랫동안 금속, 비금속, 석재 및 석탄과 같은 지하자원들을 공급하는 국내 주요생산지로 알려져 왔으나, 장기적인 채광과 비 계획적인 생산으로 인하여 매장량이 고갈되고 있으며, 대외적으로 생산 경쟁력 마저 잃어가고 있다. 이러한 문제점에 대한 해결방안의 일환으로 본 연구에서는 강원도내에 산재되어 있는 지하자원의 분포, 자원 생산시설 및 생산량, 경제성, 자원개발, 환경문제 등 자원관리에 필요한 제반사항을 수행할 수 있는 강원지역 자원 종합관리 GIS 시스템을 개발하였다. 이 시스템의 개발은 방대한 양의 정보 조사 및 저장, 오랜 개발기간, 많은 소요인력 및 개발 비용이 요구되기 때문에 본 연구에서는 조기에 자원관리 GIS 시스템을 개발하여 이와 관련된 생산 및 연구 분야에 조기에 적용할 수 있도록, 일차년도에는 현재 석재복합 신소재제품 연구센터의 집중적 연구대상 지역인 태백지역에 대한 탄광지역을 중심으로 자원 종합관리 GIS 시스템을 개발하였다. The Kangwon province has been well-known to be one of major underground resource producing districts which are mainly supplying metals, non-metals, stones, and coals. However, due to the long-term mining and unplanned production, the natural resource reserves have been rapidly drained and oversea production competition has been losing. In this study, we has developed a GIS system for regional resource management in the Kangwon province, which can operate, maintain, and manage the distribution of underground resources, resource production facilities, production and economic development, and environmental issues. The development of this system requires the collection, analysis, evaluation, and storage for a huge amount of research data, and in addition, the long period of time, the big research man power, and big development cost. Accordingly, to shorten the development period of time and to early apply itself to production, this stage of study has been intensively developed a regional resource GIS system for managing the mines scattered in the Tabak province, which is one of hottest RRC's research areas.

To study nosologically the Korean shaman's initiation sickness, 'Shin-Byong', the authors investigated 29 shamans with Symptom Check List-90-R(SCL-90-R) and questionnaire without visiting and interviewed 70 shamans using SCL-90-R, questionnaire and The Schedule for Affective Disorder and Schizophrenia-Lifetime(SADS-L). All shamans were located in Seoul. The results were as follows : 1) Among symptom groups of SCL-90-R, 'Shin-Byong' were associated with higher scores in depression, somatization, psychoticism and hostility group in descending order. 2) With DSM-Ⅲ-R classification, 87.2% of 'Shin-Byong' cases were mood disorders, Another 8.6% of cases were somatization and dissociative disorders and two disorders were related with dissociative phenomenon. Considering the diagnosis of manic episodes in this study, it seems to be a part of dissociative phenomenon, 'Shin-Byong' is the syndrome that is mainly composed of depression and disorders, which are related with dissociative phenomenon. 3) Shamans have teleologic thinking that 'Shin-Byong' is the phenomenon to receive spirits and diagnose intuitively. They think the main therapeutic method is recieving spirits, In conclusion, 'Shin-Byong' isn't a real disease entity but it is a shamanistic disease concept transformed during the shamanistic therapeutic process for depression patients with high dissociative tendency and dissociative disorder.

The purpose of this project was to find out design elements of patients' uniform which satisfied needs and wants of patients and nurses. Data were obtained via a self-administered questionnaire from 127 patients who were admitted and nurses who employed to Hanyang University Hospital. The questionnaires were composed of dissatisfaction of exiting patient's uniform, evaluation criteria, design preference, and demographic factors. For data analysis, Descriptive statistics, one-way ANOVA, and Duncan test were employed. The results of this study were as follows; 1. Patients and nurses considered important design elements of neckline, sleeve length, waistband of the pants, and number of pocket. 2. There were differences in dissatisfaction of exiting patient's uniform related to role types. Patients considered factors related to movement such as comfort, easy to dress more importantly, while nurses considered factors related to affairs such as convenient for medical treatment, classification of size, and colorfastness to the laundry more importantly. 3. There was a significant difference in evaluation criteria of patients' uniform related to role types. Nurses considered more important expressive and economic criteria, while patients considered more important functional criteria than others. 4. There was a difference in deign preference of patients' uniform related to role types. Patients preferred uniform design which composed of U-neckline, sleeve of three-quarter length, pants of ankle length, elastic-band with a drawstring, and colors of pink and light green, while nurses preferred design which composed of round neckline, long sleeve length, pants of floor length, and colors of light green and light blue.

The purpose of this project was to design a patient's uniform which gives functional and psychological satisfaction to the patients. The project was developed to follow the design process. That is, the project was based on the survey which is on dissatisfaction of exiting patient's uniform, evaluation criteria and design preference for patient's uniform. The result of the survey was reflected to the design of new patient's uniform for Hanyang University Hospital. The uniform consists of a shirt and a pair of pants. The style of the garment is comfortable box-silhouette for ease and action. The shirt has a compromised neckline of U-neckline and round-neckline. It has buttons on front for closure, a patch pocketon left side of the garment. It also has three-quarter sleeves to complement dissatisfactions on the length and the distinction of seasons. The button extension was deeply given to avoid becoming open. To give decorative accents, piping was added. The ankle-length pants aredesigned to satisfy the need for shortening the length of existing uniform pants. The waistband of the pants has both closures, a drawstring and an elastic band, to make up for the dissatisfactions on durability and slip-off problems. The colors, white, light blue, pink, and yellow, are used to give a psychological sense of security to the patients. The flower symbol of Hanyang University was used for the textile surface design. Therefore, this project is worthwhile to present more systematic and scientific approach for patient's uniform design which gives functional and psychological satisfaction to the patients.

With the widespread use of fertility medications and techniques of in vitro fertilization, multiple gestation has become epidemic in modern obstetric practice. Delivery of the initial fetus in a multiple gestation usually is followed by delivery of the subsequent fetus or fetuses shortly thereafter. However in rare circumstances, the delivery is delayed for days due to disappearance of uterine contraction after delivery of the first fetus. When uterine activity ceases after the delivery of the first neonate, a policy of nonintervention may be considered in case of an immature or very premature delivery, in order to achieve a gestational age for the remaining fetus(es) more compatible with neonatal survival. We report a case of twin gestation with prolongation of the delivery interval between the twins for 46 days.
