This study was conducted in order to determine width, length of lung by radiographic method. The measurements carried out on normal chest X-ray film of 1,036 persons who took the radiograph from the April of 1977 to the June of 1978. As a result of this study, the following conclusions were obtained: 1. In the case of male, the average width, and length of both side lung size from new birth to nineteen of age was larger than female with the exception of partly age group. 2. Lung size in average width at adult was from 27.60cm to 29.20cm and female was 25.10cm to 26.22cm. 3. The mean length of left lung at adult was from 26.32cm to 25.27cm in female. 4. The average length of right lung at adult was from 25.8cm to 28.35cm in male and female was from 24.86cm to 25.17cm. 5. It was found that lung sige in width and length was slightly increased until 39 years of age, but was trend to decrease it of lung in the age of 40 years old. 6. In the case of adult, the difference of the average length between right and left lung, the length of right lung was slightly shorter than left that.

A rupture of a dissecting aneurysm of the aorta is life threatening disease and calls for emergency surgical treatment. The author recently experienced one case of ruptured dissecting aneurysm of the descending thoracic aorta complicated with left hemothorax who was recovered after emergency operation of Aug. 11, 1976. The patient was a 43 years old farmer with known hypertension [260/120] for 20 years but without any venereal disease and had experienced sudden throbbing chest pain. Chest film and aortogram revealed this case ruptured aneurysm of descending thoracic aorta complicated with left hemothorax. In this case, large dissecting aneurysm extend from proximal part of left subclavian artery below diaphragm and involved with 3.0 and 4.0cm sized elliptical rupture in proximal part of descending thoracic aorta. And so, neither fenestration procedure nor replacement of dacron artificial vessel was suitable for this case. Finally, only the rupture site of aneurysm was treated by covering with fibrous pleura and teflon patch. The post-operative management of this case was planned to control hypertension with antihypertensive drugs. The follow-up was possible up to date about 2months. The patient has been doing well with ordinary activities except mild chest discomfort.

The purpose of this study was to evaluate the frequency of congenital missing teeth and supernumerary teeth in cleft patients. The subjects were divided into bilateral cleft lip and palate(BCLP), unilateral cleft lip and palate(UCLP) and cleft palate alone(CP alone) groups. 97 cleft patients(BCLP 15, UCLP 70, CP alone 12) between 6-20 years old were evaluated. Panorama film, Orthodontic chart and initial intraoral photogram were employed for this research. The obtained results were as follows. 1. The incidence of congenital missing teeth in total cleft samples was $57.7\%$, and the incidence of supernumerary teeth was $26.8\%$. Each incidence was higher than non-cleft. 2. The incidence of congenital missing teeth was the highest in BCLP and the lowest in CP alone. 3. The number of congenital missing teeth per perso was usually one, and the frequency was higher in the maxillary lateral incisors$(67.8\%)$, and maxillary second premolar$(14.9\%)$ than other teeth. 4. Most of tooth number anomalies in cleft patients were found in maxilla, especially adjacent region to the cleft site.

The purpose of this study is to analyze the propriety of portable digital X-ray Equipment for Emergency Medical Services in Daejon Emergency Medical Center in Korea. The major instruments of this study were Korean Self-Analysis Opinionnaire, Questionnaire contains 35 items which measure emergency medical personal opnions. To take the analysis of data, the total of 92 persons were investigated in Medical Information Center in Daejon Metropolitan City from 2005. 20. April to 2004. 25. May. The data were analyzed by the path analysis SPSS program. First, portable X-RAY equipment is needed to apply it to emergency. Second, it should have small and light structure compared with old equipments and have high voltage generator unit for X-RAY using inverter. Third, it should be able to send the shot data that is digital detector type without film to doctors in emergency center.

The recurrence of an anterior mediastinal mass was discovered incidentally on the chest film for an asymptomatic 72-year-old female. She underwent the mass resection at the same site in 1989 and was diagnosed as a paraganglioma of the anterior mediastinum. She had poorly controlled hypertension which was converted into normal blood pressure after the first operation. During the follow up, the catecholamine levels were within normal limits, and there were no evidence of recurrence of the tumor. However, 6.3 years later, the mass recurred at the same anterior mediastinum. The patient had no hypertension and catecholamine levels were still within normal limits. The recurring mass was successfully removed and had the same histological findings - recurring paraganglioma.

The purpose of this study was to research the limits of sports films from the perspective of social structural on the category, the material, the formulas and the mixture of the materials in the movie. The results were as follows: First, Sports films have been faced with the basic problem as to what a standards the category were classified with because of the conceptual confusion about what sports movie was. Second, sports movies could not catch up with a lot of changes in the movies. Third, sports movies were confined, without flexibility, within old fashioned formality of stories which prevails in modern sports. Lastly, they didn't have the mixture of the materials due to the fixed recognition on sports.

Sports-related knee injuries frequently occur in adolescent period and fractures are more common than ligamentous Injuries in this age group because of physiologic characteristics. We operated an adolescent soccer player with lateral femoral epiphyseal injury using arthroscopic assisted reduction and infernal fixation. In $2^{nd}$ look arthroscopy and metal removal at postoperative 2 years, articular cartilage was healed with good congruity and lower extremity entire long film showed normal axial alignment without residual deformity.

In this study, the influence of contact pressure on the variation in coefficients of friction between porcine knee joint cartilage and Co-Cr alloy in a repeat pass sliding motion was investigated. Flat-ended cartilage pin specimens(9 mm diameter, 8 mm long) were prepared from porcine(6 months old) knee joints by a drill-type punch. Friction tests were conducted by using a pin-on-disk type friction tester for an hour in PBS lubricated condition under the contact pressures of 0.5, 1 and 2 MPa with 50 mm distance per a cycle at ambient condition. As a result, coefficients of friction increased as the test duration increased for all contact pressures. The maximum coefficients of friction were 0.082, 0.06 and 0.098 for 0.5, 1, and 2 MPa, respectively. It showed that coefficients of friction of porcine knee joint cartilage against Co-Cr alloy depended on the level of contact pressure and related to squeeze film lubrication mechanism.

This is clinical report of one patient with pneumonia in stroke who improved with the administration of an herb drug. During treatment for stroke, he broke out with pneumonia, a complication of stroke, which was confirmed by chest radiography. He was administrated Hwangkibyulgap-tang with antibiotics because of old age middle stage pneumonia. After administration, the symptoms improved and chest x-ray film showed no pneumonic finding. This result suggests that oriental medicine is an effective treatment for pneumonia but more clinical case reports are needed.

A 51-year-old man developed diplopia while driving. The brain CT film demonstrated a hemorrhage in the left midbrain and thalamus. On our first diagnosis after 8 days from onset, partial ptosis and limitation of adduction in the left eye were detected. We evaluated that the patinet's digestive system was weak, so that treated the patient with Bojungikki-tang and Sa-am acupuncture Bi-Jung-Geouk(脾正格). As a result, limitation of adduction was recovered to about 90% of normal range and Ptosis was recovered just likely with the normal eye.
