The authors reviewed the biological etiologies of schizophrenic disorder such as genetic, viral, neurodevelopmental, neural network, sunspots and cerebral diabetic hypothesis. The etiology of schizophrenic disorder remains to be confirmed. Although genetic possibilities were suggested by many investigators, the genetic genes and their transmission methods have not been clarified yet. The neurodevelopmental hypothesis was reviewed in detail. This hypothesis includes genetic hypothesis, viral hypothesis, obstetrical complication hypothesis, neutritional deficience theory, NMDA receptor hypofunction theory and neural network theory. The neurdevelopmental hypothesis means that several developmental trajectories, related to early brain insults as well as the genetic factors affection postnatal neurodevelopment, possibly lead to this illness. An excessive pruning of the prefrontal corticocortical, and corticosubcortical synapses, perhaps involving the excitatory glutaminergic inputs to pyramidal neurons, may underlie schizophrenia.

The purpose of this study was to analyze the elementary school teachers' perception toward the environment-related subjects in science education and to investigate their instructional methods in delivering the subjects in the classroom. The participants of this study were 300 elementary school teachers sampled from elementary schools in Kyung Nam Province. The findings of this study were as follows; First, more than half of the teachers surveyed showed that the environment-related units and contents in the science textbook were insufficient to the existing issues. Second, the large portion of teachers responded that the teaching materials in the textbook were insufficient to deliver the contents. Third, the largest portion of respondents replied that their preferred instructional method was a teacher-directed instruction followed by a case study approach. Fourth, in terms of the effectiveness of environmental education, both male and female teachers showed negative responses. Furthermore, male teachers were more negative than female teachers. Fifth, total means of their preference of the environment-related units was 3.13. The unit for sixth graders titled 'Environmental Pollution and Protecting Nature' showed the highest preference, whereas the unit for fifth graders titled 'Structure and Functions of Plants' showed the lowest preference. Sixth, there was no statistically significance in gender and their working areas. Seventh, there was statistically significant differences between male and female teachers in terms of teaching experience. In detail, the teachers with 5 to 9 teaching experience showed the lowest scores, while the teacher with more than 15 years teaching experience showed the highest scores in their perception of the units. Eighth, there was a significant difference between two groups in terms of their educational background. For example, two-year college graduates showed higher preference than four-year college graduates.

Purpose : The purpose of this study was to evaluate the effect of nutritional support with enteral liquid supplement in cancer patients receving chemotherapy for possible benefit in nutritional, immunologic and golbal function of patients. Patients and Methods : From October 1995 to February 1997, 30 advanced cancer patients receving chemotherapy were divided two roups. The Nycare group, in addition to normal diet, Nucare^R enteral supplement was given for 1week right after chemotherapy for the duration of 2 chemotherapy cycles. Control group received only normal diet without parenteral fluid supplement for 2 chemotherapy cycles. Results : Median ages were 53 end 56 years for Nucare group and Contrl group respectively. Performance scores was less than 2 by ECOG scale. All patients were stage Ⅲ or Ⅳ. The physical parameters, such as weight, arm muscle circumference(AMC) and triceps skin fold(TSF) were decreased in both groups after 2 cycles of anticancer therapy. but it was less severe in Nucare group(p<0.05). Serum transferrin was maintained in mild deficit state in Nucare group, whereas it aggravated form mild to moderate deficit in Control group(p<0.05). Serum albumin level increased in Nucare group without statistical significance. but it decreased from normal to mild deficit in Control group. Serum total protein did not change significantly in Nucare group. but in Control group, serum total protein was decreased from 7.24±0.9 to 6.52±0.5(P<0.05). Total lymphocyte count did not change significantly in both groups. Conclusion : This study shows that the nutritional support with Nucare^R was effective in the prevention of nutritional deficit status in patients receving a nticancer chemotherapy.

The present study was attempted to compare the physique characteristics by different weight classes within and among the combat sport players in order to examine the efficacy of using elite player's morphological characteristics as a model for success. Anthropometric data were collected on 176 national level players who selected from four different sport events such as 52 taekwondo (n=52), judo (n=38), boxing (n=41), and wrestling (n=45). Weight classes were categorized into four groups such as <60kg, 65-72.9kg, 73-80.9kg, and >81kg, regardless of original weight classes of each sport events in order to compare the different sport events. Measurements taken included age, height, body mass, nine skinfolds, 10 girths, six breadths, and six lengths. Means and standard deviations were calculated for endomorphy, mesomorphy, ectomorphy and ponderal index (height/cube root of weight), and somatotype attitudinal distance (SAD) and mean (SAM) in three dimensions for the total samples as well as for each weight category and sport events. The differences among the individual somatotype components were examined by ANOVA. It was revealed that the mean differences of Ponderal index among sport events (F(3,160)=34.66, p<.001) and weight categories (F(3,160)=11.41, p<.001) were statistically significant. Taekwondo (42.7) and boxing (42.4) were higher than judo (40.8) and wrestling (41.2). Light and middle categories such as <60kg (42.4) and 65-72.9kg (42.1) were higher than light-heavy and heavy categories such as 73-80.9kg (41.4), and >81kg (41.0). There were no differences among the sport events in SAMs, i.e. dispersion of somatotypes for their mean (F(3,160)=0.62, p>.05). However, differences in SAMs were found among weight categories F(3,160)=3.56, p<.05). Although no differences were found among the sport events in SAMs, mean somatotypes of the three components (endomorphy, mesomorphy, and ectomorphy) were significantly different (p<.05) among the sport events. The mean somatotypes for taekwondo (2.4-4.5-2.7), judo (3.1-6.7-1.4), boxing (3.0-5.0-2.5), and wrestling (2.8-6.1-1.6) are all relatively high in mesomorphy. Endo-mesomorphs are dominant at all combat sport events. The mean somatotypes for <60kg (2.4-5.0-2.5), 65-72.9kg (2.5-5.3-2.2), 73-80.9kg (3.1-5.8-1.8), and >81kg (3.6-6.1-1.5), regardless of sport events, showed that somatotypes were more endo-mesomorphic with increased weight. Taekwondo competitors were more balanced-mesomorphs overall and were not as mesomorphic as wrestling or judo competitors. Judo competitors were the most mesomorphic with being mostly endo-mesomorphs. Boxing competitors were less mesomorphic overall as well as being more ectomorphic. Wrestlng competitors were most like judo competitors. Regardless of sport events, endomorphy and mesomorphy increase and ectomorphy decreases with increased weight. Endomorphy levels are similar between sport events for each weight category. Judo competitors are the most mesomorphic and least ectomorphic among sport events for each weight category. Based on the mean somatotype plots by sport event and weight category, somatotypes show the trend to be more endo-mesomorphic with increased weight. The somatoplot change is in the direction from right to left away from the ectomorphic comer of the somatochart for all sport events. The somatotype results of this study are similar to those from studies of Montreal Olympic weight-classified sport participants.

The purpose of this study was to ivestigate the actual status and the causes of injuries of collegiate Taekwondo competitors. The questionnaire composed of 25 items was used as the research tool for this study. The respondents were 214 collegiate Taekwondo competitors(171 men and 43 women) who participated in the nationwide university Taekwondo championship tournaments early in 1999. Chi-square(X?) was used for the statistical procedures. An α=.05 probability level used for all tests of statistical significance. The results of this study were as follows: 1) More than 97% of respondents had experiences of the injuries related to Taekwondo, and Male competitors had more injury experiences than female competitors. 2) The injuries happened more frequency during practice than during competitions. 3) Both men and women were injured most frequently by the foot attack techniques, especially Front Turning Kick. 4) For both men and women, the most frequent injured part of the body was the leg, the second arm, the third face, the forth trunk, and the last head. The most frequent injured part of the leg was the knee for both men and women, that of the upper extremities was fingers for both men and women, and that of feet was ankles for men and top sides for women. 5) The 71.3 % of men and the 66.7 % of women with injured experiences continued to prantise or compete under the imperfect recovery from injuries. The 28% of men and The 33.5 % of women responded that there was not any expert for medical service at that time of injuries.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Nowadays, Water is deteriorating with several reasons such as increase of wastewater which is flowed into river and limitation of water resource. Therefore, we concentrate on plans for securing of water resource by reusing wastewater treatment effluent. In this study, reuse system was organized using submerged membrane bioreactor(SMBR) consisted of anoxic, select, and aerobic tank with membrane as plan for solving problems mentioned above and optimized operating hydrauric retention time(HRT) was found by comparing with the characteristics of treatment with several HRT. Also, the lst floor and 2nd floor membrane module were analyzed to find more effective operating condition in SMBR. Specific characteristics of treatment for waste water SMBR was represented as follows. we could know below 10㎎/L of BOD, below 5㎎/L of COD, 0 ㎎/L of SS without regard to change of HRT, which was satisfied with the standard of reuse water. Optimized HRT was 2.3hr and by composing the 2nd floor membrane module, air flow rate could be reduced 28.5% lower than of the 1st floor membrane.
