The purpose of this thesis was to investigate plato's view of body and soul from the core of his philosophy Idea, and its influences of his physical thoughts. Some important points of plato's physical thoughts were as follows. 1. In contrast to the general concept that Plato was the mere philosopher of metaphysical dualism an regarded the body as inferior to the soul, he compared the baby to thing and the soul to Idea, and suggested an inseparable relations between body and soul. 2. Plato emphasized physical education to achieve his " Ideal state" in which the great citizens and rulers could be brought up. 3. Plato insisted that physical education should go along mental education of the perfect character building and for the first time promoted firmly the position of that to one of two maintenance in the history of the world physical education. 4. On the basis of ideological thought of physical thoughts, Plato regarded physical education as essential in order to bring up the whole man who was harmonized and balanced with in his mind and body. 5. Plato explained physical education in detail from nursing period, infant period, juvenile period to the youth period. 6. Plato regarded the proper ingestim of nutrition along with the exercise as the principle of physical education. 7. Plato demanded to build three Gymnasiums respectively in the city and in the suburbs. cavalry school and even the teacher's houses. And he insisted that the facilities should be always opened for the enough use. In case it could not be fulfilled, he suggested lawful settlements. 8. In the general rules of personnel administration, Plato discoursed on the duty, qualification and organization.

The purpose of this study was to find out if the mental practice for a certain period will influenced the record improvement of ball-throwing or not. We randomly picked out forty boy student subjects who were in the third grade in middle school. We divided the subjects into five groups-the first group (only mental practice), the second (physical practice after mental practice). the third (mental practice after physical one), the fourth(only mental practice), and the fifth (non practice)-and had each group try the practice three time, every week for eight weeks. through the close comparison and analysis over the records measured before and after the practice, we came to a conclusion like this : 1. Only mental Practice isn't effective. 2. Physical practice, physical after mental practice, mental practice after physical one, and all influence the record improvement of ball-throwing. 3. There is no any meaningful difference among physical practice, mental practice after physical one, and physical practice after mental one with each other. 4. Mental practice has no effect on the record improvement of ball-throwing.

Demodulation wants to adaptive equalizer to minimize interference of intersymbol which generate in multipath fading channel results from signal time and variety multi propagation through channel in digital radio network systems. Therefore using transition ratio of transfer and receiver system and the number of forward and backward using existing individual taps, we study improvement algorithms which generated bit error ratio by signal in frequence select fading. We analysis and compare linear equalizer and decision feedback nonlinear equalizer. Proposed algorithm is more efficent in fading environment when compared of step size by channel character which estimated existing least square and ITLMS algorithm. In this paper, using ITLMS algorithm by decision feedback BER is reduced for intersymbol interference by narrowband TDMA multipath fading in invironment without individual tap weight overlay.

Because of the merit of nonoperative management of blunt hepatic trauma, which is the avoidance of operative morbidity, the use of nonoperative management has been extended. However the indications for such treatment have not been sufficiently determined. To suggest possible criteria for nonoperative management, we reviewed 95 cases with blunt hepatic injuries which were confirmed by abdominal exploration or abdominal CT in Gyeong Sang National University Hospital from January 1992 to October 2000. Of the 95 patients, 38 patients were treated with operation and 57 patients treated with nonoperative management. We analyzed the patients for age, sex, cause of injury, injured organ, injury grade, transfusion amount, and shock on admission, complications and mortality. The results are as follows; 1) The peak incidence of age was in the 3rd decade (20%), and the male-to-female ratio was 3:1. 2) The most frequent injury mechanism was traffic accidents (40, 42%). 3) The most frequently used diagnostic modality was abdominal CT (95 cases) in the nonoperative and the operative group. 4) On the liver injury scale of the American Association for the Surgery of Trauma (AAST), 13 were grade I, 18 were grade II, 10 were grade III, 13 were grade IV, and 3 were grade V in the nonoperative group ; 1 were grade I, 6 were grade II, 18 were grade III, 8 were grade IV, 4 were grade V, and 1 were grade VI in the operative group. 5) Between the nonoperative and the operative groups, there were significant differences in the systolic blood pressure in the first 8 and 24 hours, transfusion amount, and GOT/GPT level (p$lt;0.05). 6) In comparison of complication, there were 3 cases of heaptic abscess,1 case of intrahepatic hematoma, 1 case of bile leakage, 1 case of rebleeding in operative group (15.7%). There were 2 cases of intrahepatic abscess, 2 cases of intrahepatic hematoma, 4 cases of biloma, 1 case of subcapsular hematoma in nonoperative group (15.7%). In mortality cases, 6patients died in operative group. Among them, 5patiens died from DIC (disseminated intravascular coagulation) and multiorgan failure, 1patient died from ARDS (adult respiratory distress syndrome) in operative group and 2patients died from hypovolemic shock in nonoperative group. In conclusion, i) nonoperative management may be considered as a first choice in children and adults with blunt abdominal trauma and stable vital signs. ii) Patients with hemodynamically stable hepatic injury 8 hrs after resuscitation, even with an AAST OIS grade 4 injury, may be candidates for nonoperative management.

This paper is focused on practical applicability of the optical fiber sensor considering the machine center which is going to use them. Optical fibers may be fluctuated because the machine center operates as column moving type. This causes distortion of the sensor output signal. To reduce this problem, we have improved the sensor structure and its bracket. And we evaluated performances of the sensor.

Developmental anomalies arising from the branchial apparatus include cysts, external sinuses, internal sinuses, and complete fistulas. Second branchial cleft cysts are by far the most common among these anomalies. It may occur at any age, being most common in the third decade, and more frequent in the male than in the female. It usually presents a smooth, round, nontender fluctuant mass located between the level of the tragus and the clavicle along the anteromedial border of the sternocleidomastoid muscle. It is lined by respiratory or squamous epithelium unless inflammation is present. The considerable amount of lymphoid tissue may be found beneath the epithelium. The treatment of choice of branchial cleft cyst is surgical excision. If the lesion is acutely infected, however, it is essential to relieve the infection prior to the surgery This report deals with two cases of second branchial cleft cyst. In case 1, the cyst had rapidly increased in size over pregnant period. In case 2, the patient presented the swelling in the left neck, and had the history of incision and drainage because of misdiagnosis as submandibular space abscess. The infection was treated by antibiotic therapy in the first place, and then complete surgical excision was made. There was no evidence of any recurrence or complications for these 3∼4 years.

The purpose of this study was to know the effect of learning attitude of students in physical training class according to physical educators' leadership behavioral types. To verify the hypothesis, girls' middle school students were selected as stratified sampling. That is 3 middle school located in Tae-an, Chungcheongnam Do. In real research, the number of students is 245. The questionnaire for learning attitude used in this study was the one that was made up and developed by KEDI(1992). Also for this study, the questionnaire of leadership behavioral types for physical educators was applied what Jung Moo-young(1977) has reconstructed based on Lewin, Lippitt and White's study(1939) which had classified 3 different leadership behavioral types - the democratic, the laissez-faire and the authoritarian behavioral types. In data processing for verifying the hypothesis, MANOVA were used. The results analyzed by hypothesis and methods are as followed; 1. Students perceive their physical educators as the democratic type most. 2. There was a great significance between the students' perception of the teacher's leadership behavioral types and their learning attitude. In the Democratic type, students who had positive perception on their teacher have marked higher than those who perceive their teacher to be non-democratic. Also in the authoritarian and the laissez-faire type, students have made higher than in non authoritarian and non laissez-faire type. therefore, students who perceive their teacher as the democratic have marked the highest score in learning attitude.
