연구목적 : 전산화 Standard Progressive Matrices(SPM) 검사의 한국인 성인 표준자료를 확립함으로써, 간이로 지능을 평가하는 경우에도 보다 정확하게 지능지수를 추정하기 위해서 본 연구를 수행하였다. 방 법 : 18세 이상의 남녀 정상인 자원자 353명을 대상으로 전산화 SPM 검사를 시행하고, 백분율 및 표준점수(T-점수)를 기준으로 하여 표준화 자료를 작성하였다. 전체 대상군을 성별, 연령별로 구분한 후 평균과·분포가 유사한 집단은 군을 합치는 방법을 사용하였다. 한국인 표준자료에 근거하여 추정한 SPM 지능지수와 외국인 표준자료에 근거하여 추정한 SPM 지능지수를 각각 KWAIS 지능지수와 비교함으로써 타당도를 검증하였다. 결 과 : 18∼30세, 31∼40세, 41∼50세, 51세 이상의 연령군으로 구분된 한국 정상 성인의 SPM 표준화 자료를 산출하였다. 본 연구 결과에 의한 표준화 자료를 적용하여 지능지수를 추정하는 것이 현재 사용하고 있는 외국인의 표준화 자료를 이용하는 것보다 KWAIS 지능지수에 더욱 근접한 결과를 보였다. 결 론 : 18세에서 50세까지의 한국인 남녀에게는 간이지능평가도구로서 전산화 SPM 검사의 한국인 표준화 자료를 유용하고 타당하게 적용할 수 있음을 확인하였다. Objectives : We conducted this study to provide standardized data of the computerized Standard Progressive Matrices(SPM) test in Korean adults. Methods : The computerized SPM test was administered to 353 healthy volunteers aged 18 years over. We provided the standardized data(percentile and standardized T-scores) for the groups with similar mean and distribution of SPM scores, which was originally divided by age and sex. The validity of the new standardized data was tested by comparing IQs estimated by SPM and K-WAIS. Results : The standardized SPM data were provided for four age groups : 18 to 30 years, 31 to 40 years, 41 to 50 years, 51 years and over. IQ estimated by this standardized data tends to be closer to IQ by K-WAIS than the IQ estimated by foreign normative data. Conclusion : The standardized data of the computerized SPM were proven to be a useful and valid tool for measuring IQ briefly, compared with the conventional way of measuring IQ.

This study was accomplished to develope the evaluation items for inquiry learning in the 2nd grade Middle School Science for the consecutive study of the evaluation items for inquiry learning in the 1st grade Middle School Science(U-Hang Ki et al, 1984). In this study, paper and pencil test items and performance test items are made by analyzing the abilities of inquiry according to the contents and four basic experiments from each unit in the 2nd grade Middle school science. These evaluation items were applied to tke five classes of the 2nd grade of middle school to test their validity. It is desirable that performance test schuld be used for the evaluation for the abilities of inquiry which can not be evaluated by paper and pencil test. In the evaluation methods of performance test, tester evaluation, peer evaluation and self-evaluation can be applied to the science class in a multi-student class. In higher grade, however tester evaluation is more desirable than peer and self evaluation. It is found that peer evaluation and self-evaluation make possible the perfect study by feedback.

To develop the functional pear fruitlet product, we prepared dried pear fruitlet and fermented pear fruitlet, respectively. Then we investigated their general characteristics, and viable cell number changes during the storage at room temperature. We also determined preference for their tastes. Dried pear fruitlet contained more ash and crude proteins as well as minerals than fermented pear fruitlet. However fermented pear fruitlet contained higher amount of edible fiber than dried pear fruitlet. Fungi were not detected from dried pear fruitlet during the storage experiment at room temperature. Numbers of bacteria from dried pear fruitlet were increased from 1.1☓105/g at the beginning to2.6☓106/g at the last day of experiment. When we determined change of fungi number during the storage of fermented pear fruitlet, we cannot detect fungi at the beginning but we detected 4.4☓102/g of fungi at the last day of storage experiment. Bacteria from fermented pear fruitlet were detected at around 1.0☓109/g during the storage periods. Preference for fermented pear fruitlet was superior to dried one.

It is essential that we put the anticoagulant into the blood specimen of the CBC test. However, the value of some parameters in the CBC test can be changed whenever using some anticoagulants. EDTA anticoagulant is mostly used these days. There are 3 kinds of EDTA, that is K_(2-), K_(3-), and Na_(2-) EDTA. The author studies how many effects each the EDTA gets into the true value of blood specimen for MCV of RBCs. Especially we compared the MCV effect of different concentrations of 3 EDTA anticoagulants on the bias with time and instrument. Some results are gotten. In our results, K_(3-)EDTA anticoagulant shows more satisfactory MCV value than K_(2) or Na_(2-)EDTA. On using concentration of EDTA, 1.5㎎ EDTA/㎖ of blood show more satisfactory MCV value than 7.5㎎ EDTA/㎖ of blood. However, the choice of anticoagulant may be dependant on the different instruments.

The uterine cervicitis by chlamydia trachomatis(CT) shows no specific clinical symptoms except mucopurulent leukorrhea, but it causes severe complications such as endometritis, salpingitis, abortion and infertility. Fortunately, the treatment of cervicitis by CT is simple and effective, so that this infection is once diagnosed and then confirmed, the treatment is not difficult. To study the positive rate of CT infection, we collected 65 patients inflicted with mucopurulent leukorrhea in Chonan city. Specimen was collected by swab and for the detection of CT, ELISA was carried out. The positive cases are observed in 15 out of 65 patients (positive rate is 23.1%). This positive rate was rather lower than other reports, however, this results were higher we expected With this result, the clinicians keep in mind the fact that the causes of uterine cervicitis by CT occupy the large proportions as gonorrhea.

The protective and therapeutic effects of Alismae Rhizome extracts depending on solvent polarity on rat liver injury induced by benzo(a)pyrene were investigated. As parameters in serum and liver, alkaline phosphatase, glutamate oxaloacetate transaminase and glutamate pyruvate transaminase activities were observed. The results were as follows: B(a)P intoxication significantly increased alkaline phosphatase, transaminase activities of serum and liver compared with normal group. Especially CHCI₃fraction revealed the most powerful liver protective and/or therapeutic effect of 4 extracts in serum transaminase activities and in hepatic alkaline phosphatase and glutamate oxaloacetate transaminase, maybe due to presence of alkaloid, triterpenoid and flavonoid in this fraction. Above-mentioned results strongly suggested that Alismae Rhizoma be a promising liver-protective drug. So more study will be needed to find principle hepatotropic Alismatis Rhizoma.

Generally, for the fracture problem in an actual construction, three-dimensional cracks exist in most cases, and in crack propagation, the stress intensity factors KI, KII and KIII usually act in single or mixed modes. Stress intensity factors are important parameters affecting stress-strain behavior in the vicinity of a crack tip. They are used for the strength evaluation of machines, structures, and various machine elements. In fracture problems, stress intensity factors obtained theoretically and experimentally have been effectively utilized in the analytical evaluation of the effect of cracks. In the paper, the mixed mode stress intensity factors KI, KII and KIII are determined experimentally by combining the caustic method and photoelastic stress freezing method.

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.
