The purpose of this study was to find out the rationable of the construction of the reference lines using pupil position in the posteroanterior cephalometry. The PA cephalograms were taken in the forty adult subjects who had facial symmetry and normal occlusion, using pupil position market(PP market). Two weeks later, another PA cephalograms were obtained in the twenty subjects, using the same method to evaluate the reproducibility of pupil position by PP market. Two tracings were obtained from each PA cephalogram according to the method of the construction of reference line. One tracing was drawn with the horizontal reference line constructed by the line through right and left latero ­ orbitake, and with the vertical reference line constructed by the line through crista galli and anterior nasal spine; Other tracing was drawn with the horizontal referencen line constructed by the line through right and left pupils, positional differences of vertical and horizontal reference line constructed by each method were compared by angle. Six pairs of anatomic landmarks were selected and their position differences between right and left sides were measured. Horizontal and vertical differences were compared between two methods. Following results were obtained. 1. The difference of pupil position on PA cephalogram which was taken by sing PP market was 0.37 mm horizontally and 0.38 mm vertically. 2. The difference of the horizontal line between the two methods was rather big (1.04±0.71˚) whereas the difference of vertical line was small(0.71±0.62˚). 3. In the comparison of the horizontal difference of the landmarks between right and left sides, the values of difference in the pupil position was smaller than in the anatomic landmark method; however the differences were not statistically significant. 4. The comparison of the vertical difference showed the same pattern with the horizontal difference, and further the difference was statistically significant in one landmark. The above results suggest that the PP marker may be helpful for construction of the reference line in the PA cephalometric radiography.

Nowadays, artists are keenly interested to take close observation on folk arts upon reactionary idea of modern fine arts. In Korea, we have a folk game in the name of "Jong Kyung Do". To play the game, a wood chop is used. We call it Yoon-mok or wheel chop. Yoon-mok is shaped in five angles and engraved scoring marks on the surfaces of the angles. It works like a die. Yoon-mok has a perfect formative quality and beauty of texture that we can hardly over-admire it in viewpoint of modern sense of arts. In this study, I tried to reform it to be a modern sculptural unit by enlarging its size. In addition to this, a number of base materials which are generally associated with modern sculptural works have been applied, including aluminum, plastic, bronze, artificial stone and wood, etc. 15 pieces have been completed in total, and each given with a title of "Monumental Yoon-mok". In this experimental study, I attempted to relive the traditional beauty of Korea on modern arts work. In other words, a creation of modern sculpture is aimed upon foundation of traditional Korean sense of beauty. I would like to add here that I will continue and extend the study and work in the line as described in the above. I would research the folk arts in broader range, and find and recover the soul and spirit of our ancesters breathing still warm in and around them. And I will transfer them unto the present day sculptures and let them resurrect in us, so that the subjectivity of the Fine Arts of Korea be set more firm and further develope towards the world to be an arts of the world that have its origin and roots in the land of this nation. And I believe this be the way I can find and refine myself.

Background: Reperfusion of ischemic myocardium has been postulated to result in a specific oxygen radical mediated tissue injury. Iron may liberate during ischemia and we hypothesized that administration of the iron chelator, deferoxamine during ischemia would result in improved recovery after postischemic reperfusion. Purpose: To test whether iron-catalyzed processes contribute to myocardial necrosis during ischemia and reperfusion, deferoxamine was administered to block iron catalyzed hydroxyl radical formation in rabbits. Methods: Eleven rabbits were divided into two groups : control group (n=5) and deferoxamine pretreatment group (n=6). The left circumflex coronay artery was ligated for 30 minutes and reperfused for 180 minutes. Area at risk (AR) was measured by non-stained area with methylene blue injection into left atrium after left circumflex coronary artery ligation. Infarct size was measured by weighing after triphenyltetrazolium chloride staining. Heart rate was measured using electrocardiographic recording and systemic blood pressure was monitored by pressure transducer connected to the catheter in the left ventricle. Results: 1. There was no significant difference of heart rate and blood pressure in deferoxamine pretreatment group compared with control group. 2. There was significant decrease of serum iron concentration after continuous infusion of deferoxamine compared with serum iron concentration before ligation of coronary artery(P<0.05). 3. There was no significant difference of area at risk between control and deferoxamine pretreatment group. 4. Area at necrosis to area at risk was significantly reduced in deferoxamine pretreatment group compared with control group(P<0.05). The results suggest that deferoxamine infusion prior to coronary artery occlusion has a significant benefit in reducing infarct size in this model.

The purpose of this study is to reveal the factors leading to the problem of unilateral condylar fractures and suggest a treatment guideline of treatment for good prognosis in surgical treatment, The factors can be age, sex, fracture site, degree of displacement, posterior occlusion loss, post-operative alteration of condylar head position, post-operatlve condylar head resorption, and maxillomandibular fixation period. One hundred and eleven patients with unilateral condylar fractures, who were treated by surgical method from 1990 Feb. to 2000 Feb., were studied. Minimum follow-up period was 6 months. The results were as follows ; 1. In the age group of 41 ∼60, females had significantly higher complication rate than males, therefore we must be careful about treatment of female in this age group 2 In level I fractures of the mandibular condyle, because there were abundant complications when the patients were treated with fragment removal, conservative treatment is recommended over the surgical approach. 3. There were no differences in the complication rate, in the level Ⅱ, Ⅲ fractures. but were severe complications in the cases of patients treated by Dr.Nam's method or fragment removal. Therefore, open reduction and internal fixation is recommended over Dr.Nam's method or fragment removal. 4. In level Ⅳ fractures, open reduction and internal fixation is recommended 5. Although there was a higher complication rate depending on the degree of deviation, there was no correlation between the degree of deviation and development of complications in each level of fracture 6. Because the complication rate was higher in cases of condylar resorption, vertical dimension loss, and alteration of condylar head position, we must make an effort to prevent such complications during treatment

A 60-year-old female, who complained of delayed healing and swelling after extraction of left lower second molar during chemotherapy, visited our department. She had a history of a resection surgery of breast cancer and postoperative radiotherapy. The conventional radiographs showed diffuse permeative bone destruction in posterior mandibular body, which gave the first radiologic impression of osteonecrosis associated with radiotherapy or chemotherapy. And bone metastasis from the breast cancer was also considered in the differential diagnosis. On the enhanced computed tomography (ECT) the posterior mandibular body was occupied by a large expansile lesion showing central low attenuation with peripheral rim enhancement. Magnetic resonance images revealed that the low attenuated area on ECT did not show as high signal intensity as water on T2 weighted image and indicated solid component of a tumor. The final diagnosis was central squamous cell carcinoma. We present the diagnostic imaging features of the patient with special emphasis on the differential diagnosis.

This study is planned to investigate the attitude toward the safety and health management of contractor comparry. Under the contract based production system, all of activities including safety and health management in the contractor company are depended upon the contract. How to make contract influence the worker's health of contractor company. Work's health of contractor company can be protected by efforts of company of contract-out and contractor company, especially their safety managers. The modelling of the effective safety and health management system for contractor company should consider the need of safety manager of each company and employer of contractor company. Data is collected from safety managers of 3 contract out companies as electronic and electrical manufacturing industry and 55 safety managers, 57 employers of their contractor companies using self administered survey with structured questionnaire. The most of all respondents want to support from the contract out companies. The most important items supported from contract out company is the information based on the safety information network between each company. Safety manager and employer of contactor company also itemized safety education and training in the supporting system from contract out company. These results can be generalized to survey on the other industries.

Objectives : The purpose of this study is to review research papers published by Korean research groups on biophoton of human beings based on experiment subject and methodology. Methods : In order to review human biophoton research executed in Korea, all the papers published in Korean and international journals by Korean research groups were selected. Several key foreign papers were also reviewed for clarification of this study. Based on experiment subjects, experiment methodology, and interpretation of experiment results were analyzed. On each experiment, its original interpretation was directly quoted. Issues on the experiment methodology and interpretation were expressed at the end of each subject. Results and Conclusions : We found that experiments on human biophoton were compelling. However it seemed that mom experiments, especially on their sample sizes, ate needed to demonstrate its clinical application. Interpretations based on Korean traditional medicine also need to be elaborated more. In order to do accomplish clinical application of biophoton, interdisciplinary works are required. Some suggestions on biophoton experiments were made.
