The purpose of this survey is to investigate and analize the status of flower consumption by city households so that it can provide basic materials for the development of horticulture industry. For this purpose, one thousand housewives were questioned living in six large cities : Seoul, Pusan, Taegu, Inchon, Kwangju and Taejon. The results of the analysis are as follows; 1. The most favorite cut flowers by season were rose, carnation and freesias in spring: roses and gypsophila paniculate in summer : chrysanthermum in autumn : gypsophila paniculate, roses chrysanthemums and lilies in winter. 2. The uses of cut flowers was mostly for gifts(58.4%), and that of pot flowers was mostly for home decoration. 3. flower shops were the most popular place for buying cut flowers(59.5%), followed by wholesale markets(22.5%) and street stalls(16.2%). In the case of pot flower, wholesale markets were the most favorite place(32.4%), street stalls(27.9%), flower shops(24.8%), and farm houses(11.9%). The survey showed that consumers frequent a shopping place because of 'easy accessibility', and 'various varieties in stock' in the case of cut flowers and, in that of pot flowers, 'easy accessibility' and 'low price' were the main resons in the case of pot flowers. 4. The purchase frequency rate by seson for cut flowers was that 'regardless of season' was 58.1% and 'spring', 28.9%. For pot flowers, 'spring' 58.9% and 'regardless of season' 33.6%. For the day of the week cut flowers were bought most open, Saturday came first with 34.2%, Monday and Sunday followed with 27.0% and 15.5% respectively. On the other hand, Sunday came first with 42.3%, Saturday(32.5%) and Monday(8.3%) took the second and third place respectively for pot flowers When it came to the purchase time of the day for cut flowers, 31.8% of the respondents bought then between ten and noon and 21.8% between four and six in the afternoon. 5. concerning the average amount of money spent at one time for cut flowers, 33.3% of the respondents said 3,000won to 5,000won and 23.2% replied 5,000won to 10,000won. While 36.8% answered that they paid 5,000won to 10,000won and 23.5% said 3,000won to 5,000won for a pot flowers. 6. Relating to the demand of flower stores, 28.8% wanted 'low price' : 27.9%. requested 'clear markings of the prices' : and 26.4%, wanted 'abundant commodities'

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

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.

Most of the fluorite ore deposits in Kumsan district occur in the Chinsan area. Specifically, these are the Okgye, Hyongyang, Ilyang, Manak fluorite ore deposits. Field survey and fluid inclusion study were undertaken to illustrate the characters and origin of the fluorite ore deposits in Chinsan area. The results of this study are as follows; Gology of the Chinsan area is composed of Majonri Formation and Changri Fomation which belong to Okchon Group and Jurassic biotite granite and Cretaceous pink feldspar granite and quartz porphyry. The wall rock of fluorite ore deposits in Chinsan area are chiefly limestone in Majonri Formation and partly limestone in Changri Formation. The relevent igneous rocks of the fluorite ore deposits are chiefly quartz porphyry, but some are biotite granite or pinkfeldspar granite. The fluorite ore deposits in this area are chiefly contact metasomatic deposits which were formed while limestones were intruded by quartz porphyry, biotite granite and pink feldspar granite. The filling degrees of fluid inclusions in fluorite ranges 84∼95% in Okgye, 85∼95% in Hyongyang, 85∼91% in Ilyang, 92∼96% in Manak ore deposits. The salinity (NaCl equivalent weight percent) ranges 0.1∼1.5wt.% in Hyongyang. 0.3∼2.8wt.% in Ilyang. 0∼1.5wt.% in Manak ore deposits. The homogenization temperature of fluorite ore deposits in Chinsan area ranges 97.6∼191.6C in Okgye, 99∼168.4C in Hyongyang. 100∼214C in Ilyang, 122∼248.6C in Okgye, 99∼168.4C in Hyongyang, 100∼214C in Ilyang, 122∼248.6C in Manak ore deposits. These data indicate that Chinsan Fluorite ore deposits belong to the epithemal or mesothemal deposits same as the other fluorite ore deposits in Korea.
