The purpose of this study was to examine how the program of basic movement can influence and change the capability of perceptive movement among the children with autism. Four subjects (age3-5) participated in the specially designed program, three times a week for four weeks. For the purpose of this study, Oseretsky's Motor Development Test and PMDT(perception-Movement development Diagnosis Test) were used. The results were as follows; First, the upper limb performance of the children with autism showed significant changes by the movement education program. Second, along with the development of upper limb performance, the motor development index of the children with autism showed significant changes. Third, the Oseretsky spectrum of movement, of the children with autism responded to the order of mono-movement capability, hand-movement and co-operative movement. Fourth, the movement education program was more effective for the children with autism than for the retarded children in view of motor development capability. Fifth, the movement education program was more effective for the child with autism of multi-movement characteristics.

Background/Aitns: It has been reported frequently that clinical features of gallstone diseases in Koreans were different from those of Occidentals. These differences were thought to be due to inherent racial difference and acquired living habits. The purpose of this study is to evaluate whether the pattern of gallstone disease changes or not in Korea. Methods: We analyzed 5,488 cases of gallstone diseases which were reported in Korea frorn 1966 to 1994. We divided the period into 6 groups: the first period was 1,000 cases reported from 1966 to 1970, the second was 331 cases from 1971 to 1975, the third was 1,000 cases from 1976 to 1980, the fourth was 1,957 cases from 1981 to 1985, the fifth was 1,000 cases from 1986 to 1990, and the sixth was 200 cases from 1991 to 1993. Results: The age group of highest incidence was the fifth and sixth decade. The incidence below the third decade showed a decreasing tendency. In contrast, the incidence above sixth decade showed an increasing tendency. The male to female ratio was 1:1.25 to 1:1.71 and had no periological change. The duration of illness of highest frequency was below 6 months. In the case of duration above 5 years these was a decreasing tendency. The major complaints of biliary stone were right upper quadrant pain and tenderness. Nausea, vomiting, jaundice, and radiating pain showed a decreasing tendency. The major laboratory findings were leukocytosis, elevated SGOT and SGPT, elevated alkaline phosphatase, hyperbilirubinemia and hypoalbuminemia. Of these, only hypoalbuminernia had a decreasing tendency. By the second period, the main diagnostic procedures were oral cholecystogram and intravenous cholecysto- graphy. From the fourth period, ultrasonography, ERCP, CT and PTC were been used comrnonly. For the location of gallstone, the gallbladder stone revealed the only increasing tendency, the common bile duct stone had a decreasing tendency, and the intrahepatic duct stone had no periological change. From 1980, the cholesterol stone became the main composition of gallstones. But, there was no periological change between early and late 1980s. Positive bacterial culture rate was 57.0% and the most common microorganism was E. coli. Klebsiella and Enterobacter. Pseudomonas showed an increasing tendency. Of the diseases associated with gallstone, only diabetes had an increasing tendency. The frequency of residual stone had an increasing tendency. Conclusions: The age of peak incidence of gallstone diseases was the fifth and sixth decades and there was a little predominance in females. From 1980, the cholesterol stone becarne the main composition of gallstones. For the location of gallstone, the gallbladder stone showed an increasing tendency and the common bile duct stone revealed a decreasing tendency. These suggested clinical features of gallstone diseases in Koreans are somewhat similar to those of Occidentals. (Korean J Gastroenterol 1997;29:352 - 361)

Fiber reinforced composite materials have been used in wide application field ; air and marine craft fabrication, sports googs, and the other industral structures and instruments, because of their excellent mechanical strength with their light weight. The carbon fiber-epoxy composites have been used very widly with their high modulus and their relatively low price of fabrication. Epoxy resin is one of thermosetting plastics, so, the various processes of curing sharply affect the mechanical properties of the result composite materials. In this report, the samples manufactured with various curing processes are analyzed by Differential Scanning Calorimetry, Thermogravimetric Analysis, Izod Impact Strength Test and so on. In the process of curing, because the viscosity of the system is very sharply rise up on the progress of curing, it must not attain completely cured state. In this study, the two step curing process is detected more effective ; first step curing executed at relative low temperature and second step of post-curing at high temperature.

The female pigs of 50kg body weights were phlebotomized and the heparinized blood was centrifuged for separation to blood plasma and corpuscles. The hematocrit, per centage of the blood that is red cells, was reschuffled of 20%, 40%, and 60% using blood plasma or 0.9% NaCl solusion. The sedimentation rates of red blood cell obtained at 27℃±1℃ are summarized as follows. 1. The sedimentation rates of hematocrit 20% of RBC at first one hour were 34±1.5mm in blood plasma and 2.4±0.7mm in NaCl solution. 2. The RBC sedimentation rates of hematocrit 40% at first one hour were 2.4±0.4mm in the plasma and 1±4mm in NaCl solution. 3. The rates of hematocrit 60% were 1mm in the both solutions at first two hours and no difference for the 6 hours. 4. The sedimentation rates of RBC were more diminished by higher PCV%, i.e. there was a reverse relationship between the sedimentation rates and PCV%. 5. The RBC were sedimented more slowly in the NaCl solution than the plasma and the difference was smaller by higher PCV% and no difference at more than PCV 60%. 6. The sedimentation rates against time were almost liner for several hours.

In the electronic commerce, most consumers will have the mind that they look for the information of products and services and estimate alternatives investigated and choose right product, which they're likely to purchase in common commercial market. But In the E-commerce, consumer can not see the real products. And consumers have to be waited for a long time of delivery and the increase of many crime and fraud through the software makes the Anti-trust of E-commerce with credit and security problem included the extraction of personal information related to the privacy policy. This study examines the causes of delaying purchase decision related to the perceived risks of product, risk reduction behavior and consumer characteristics in electronic commerces. First, in order to investigate the differences of the perceived risk between heavy purchase group and unpurchase group, the three kinds of the perceived risk were examined. Second, risk reduction behavior related to a specific financial risk, social risk, and psychological risk were surveyed to research different characteristics between product and service. Finally, the relation between three kinds of the perceived risk and risk reduction behavior was analyzed. A survey was conducted to collect data with the questionnaires. 136 questionnaires were used for the analysis The results of study show that ; A man who have ever visited E-commerce site and internet shopping mall reduced the perceived risk more than usuals. In many types of risk reduction behavior, pre-purchase deliberation is The most useful for risk reduction behavior, word-of-mouth, brand loyalty and so on.

The Organ Injury Scaling Committee of the American Association for the Surgery of Trauma recently published a consensus classification of hepatic and splenic injuries. The hepatic and splenic injury scales, based on parenchymal laceration and intrahepatic hematoma, include grade 1 to 6 and grade 1 to 5 respectively, representing the least to most severe injury. Forty-eight patients with hepatic and splenic injury were evaluate by abdominal CT from January 1995 to May 1996 and we compared abdominal CT grading with operative grading. Four CT grades did not correlate with operative finding. CT grading showed a sensitivity of 80%, specificity 80% in regard to operative grading. We conclude that 1) CT is an accurate technique to determine the extent of hepatic and splenic injury. 2) CT grading of hepatic and splenic trauma has a high correlation with operative grading.

Study objectives: To compare the quality of CPR provided by medical students and pre-EMTs perfoming three-rescuer CPR with that achieved by same students trained to provide standard two-rescuer CPR and to find the most effective method of resuscitation and to educate this methods to students. Material and methods: From July 1 to September 30, 1996, we had trained 60 groups consisted of the medical students, students of EMS technology and pre-EMT. Each group practiced two-rescuer CPR and three-rescuer CPR for 120 minutes with Resusci? Anne and perfomed CPR for at least 3 minutes without feedback. To eliminate any visual cues of perfomance the mannequin's recorder was hidden. Each actions were recorded by Resusci? skillmeter and Laerdal printer. To compare the quality of two-rescuer CPR and three-rescuer CPR, we analyzed the data by SPSS with paired t-test. Results: Three-rescuer teams delivered a mean minute ventilation and a mean minute cardiac compression substantially greater than that produced by two-rescuer teams(11.30±1.85 vs 9.09±2.22, p<0.001; 99.22±12.42 vs 95.12±15.75, p<0.001). Three-rescuer teams produce the more correct actions in chest compression and ventilation(93.84±7.56% vs 83.49±16.94%, 90.90±9.33% vs 77.00±17.06%). Conclusion: Three-rescuers can produce better CPR than two rescuers when a bag-valve-mask devices is used and the technique is easily learned and readily retrained, so we think that repeated education and training of this CPR methods to students is needed.
