The treatment of mandibular subcondylar fractures is a matter of controversy. The majority of mandibular subcondylar fracture are treated by closed reduction, but the displaced or dislocated mandibular subcondylar fractures may be treated by open reduction. The characteristics of open reduction are the anatomical reduction, the functional restoration, the rapid function, the maintenance of vertical ramus dimension, the better appearance and the less resultant TMJ problem etc. When an open reduction is considered, the wire, miniplate, lag screw and Kirschner wire are available with internal fixation. Of these, Kirschner wire is a simple method relatively and correct positioning of the wire achieves rigid fixation. But many open reduction methods for mandibular subcondylar fractures require extraoral approach. The extraoral approach has some problems, the facial scar and the risk of facial nerve injury. On the other hand, the intraoral approach eliminates the potency of the facial scar and the facial nerve injury, but is difficult to access the operation site. Since the intraoral approach was first described by Silverman (1925), the intraoral approach to the mandibular condyle has been developed with modifications. The purpose of this article is to describe the intraoral technique with the Kirschner wire on mandibular subcondylar fractures. Conclusion : The intraoral reduction with Kirschner wire on mandubular subcondylar fractures avoids the facial scar and facial nerve injury and is simple method to the extraoral approach. And it has minimal morbidity and better esthetics.

How much the Korean children's physiques changed for half a century sionce 1919 when the Korean students were taken their physical examinations at first. Investigating and analizing the periodic shifts, I found out the fact that the physical growth rates of them had been raised in accord ance with cultural progress and economic development. The 14-year-old boys have grown into 12.34㎝ in their heights for half a century. It implies the possibilities that they can grow still higher hereafter. I suggest that we have to establish the normalization of physical education and desirable educational policy. Then we will also inherit the healthy physiques to our posterity.

The aim of this study is to investigate if learning through completing activities of physics conceptual model is more effective than learning through traditional teaching method based on didactical lecture. Completing activities of physics conceptual model is for the students to complete an incomplete conceptual model of physics given by the authors. For the study, four classes(140 students) from two high-schools were sampled and divided into experimental and control groups. After pretest, 3 periods of instruction were implemented, and then, post-test was taken. For the experimental group, instructions with completing activities of physics conceptual model were implemented, while, for the control groups, traditional instructions based on didactical lecture were implemented. According to the statistical analysis of test results, there was a meaningful difference statistically in post-test between experimental groups and control groups, while there was no meaningful difference statistically in pretest results between them.

LEISURE 로서의 自由學藝敎育에 관한 考察

김성룡,김형준 群山大學校 1995 論文集 Vol.22 No.-

It is said that the identity of American and Europian culture is based on the Ancient Greeks. In Ancient Greeks, the liberal arts were valued highly as the most important and the basic way to make human value, the existence of human beings and the universal values noble and honorable, which were the basis of the indivisual's happiness, the stability of democracy and the democratic society. That's way where the American and the Europian society face to the politician, social and humanistic crisis, they tend to come to life again the spirit of Ancient Greeks culture. The aim of this paper is to think about the relationships of leisure and liberal arts, referring to the work of M. J. Alder, who has seek the policy of the learning society and the way of liberal arts education in USA.

The field emission characteristics was studied by simulation for an under-gate structure with a ring-shaped CNT emitter. The electric field strength was sharply peaked along the inner rim of the CNT emitter. For positive gate voltages the electron emission was concentrated there. With an assumed field enhancement factor of 1000, the operating voltage was about 7 V, only 1/10 of those of other reported structures. The effects of the gate bias polarity on the electron emission and the electron trajectories were discussed.

김성룡 群山敎育大學 1973 論文集 Vol.6 No.-

The safety problem, one of the five aims in physieal education is based on the respect of human life. It is to keep the safety of others as well as individual and to maintain the public peace and order. The safety education should be practiced from the childhood so that is might be habituated. Moreover it can not be accomplished successfully if the school, home and the government institution do not support and cooperate with it. In this paper I have intended to suggest some ways of preventing the human life from the accidents caused by the development of machine civilization in our days.

Concentrated solution was prepared for a sol-gel process of BaTiO₃. Barium hydroxide and Ti-isopropoxide were used as the raw materials with methanol and isopropanol as solvents. Dense ferroelectric polycrystalline BaTiO₃thin films with the perovskite structure were fabricated by spin coating of the prepared concentrated solution on a few substrates. From XRD investigation, it was confirmed that tetragonal phase of polycrystalline BaTiO₃powders are formed after heat treatment above 550℃ in air and grain-oriented BaTiO₃thin films are obtained by coating of 0.06M concentrated solution on the substrates. It was observed that surfaces of thin films deposited on the substrates by our methods were formed crack-free and uniformly. The thickness of thin film which depends the concentration of the solution was 400∼900Å for 1 time coating, which was confirmed by SEM analysis. Ceramics and thin films show dielectric constant of 4600 (at 1㎑) and capacitance 300∼800㎊ (at 1㎑) at room temperature, respectively.

The purpose of this study is to analyze and grasp the actual lumbaginous condition and relevant factors of 1,182 beauty artists of beauty shops in 5 metropolitan cities, small-to-medium cities, and fishing or agrarian villages for 3 months from June 20 to September 25, 2000 through questionnaires. 1) They showed 61.0 percents in her twenties, 66.4 percents of unmarried women from all the female objects, 70 percents in high school graduates as educational background, 52.4 percents in metropolitan city as service place, 25.4 percents in smoking rate, 71.6 percents in drinking rate, 48.1 percents in general bed as condition of bedroom, 17.9 percents in exercising rate, 53.6 percents in 'little eating', 39.6 percents in two or three centimeters of heel, and 89.5 percents in hair as beauty-related professional field. 2) The rate of lumgaginous experience of beauty artists was 83.5 percents. They showed higher rate of 91 percents in the thirties and forties, 92 percents of the married, 93.9 percents in junior college graduates, 97.2 percents in higher economic classes, 88.7 percents in smokers, 85 percents in general bed, 89.3 percents in sleeping on one's face, 85 percents in swimming, 92 percents in stretch, 86.7 percents in 56 to 60 kilograms of weight, 89.7 percents in group O blood, 90.5 percents in experienced women of abortion, 97 percents in heel over 8 centimeters, 58.3 percents in 'feel much fatigue', 93.6 percents in inconvenient chair of beauty shop, and 89.4 percents in a lack of recess than other group. 3) The more women who have been experienced in lumbago, the higher their social treatment(p<0.01), income(p<0.001), working time(p<0.05), job potentiality(p<0.05), inner affinity(p<0.05), and job satisfaction of environment(p<0.001) were. Women who suffered much stress related to job environment(p<0.001), client(p<0.01), and their duty(p<0.01) showed high rate of lumbaginous experience. 4) In degree of lumbago by characteristic, there was the significant difference in age over 50-years-old, unmarried women, college graduates, service of small-medium cities, higher economic classes, smokers or drinkers, hot-floored room, sleeping with ransack, stretch or swimming, group A blood, fat body, experience of abortion, 6 to 7 centimeters of heel, convenient chair of beauty shop, insufficient recess, lumbago continued for one to the three months in comparison of other group. 5) There were variables of posture such as to place materials under one foot(p<0.001), to lay arm on armrest and desk(p<0.001), to pull materials near body while lifting them (p<0.05), to sometimes use anodyne(p<0.01), not to lift also light materials(p<0.001), to be inconvenient in sleeping(p<0.001), to be absent at job for two or three days(p<0.01). The degree of depression(p<0.001), had the significant effect on the degree of lumbago(32.7%). The results are as follows : Beauty artists have faced upon dangerous job environment to cause lumbago. The more the industrial society will be developed, the more their burden of service will be increased. In addition, the occupational stress and posture of beauty artists who showed high job satisfaction and high economical level became major factors which have had an effect on their lumbago. In conclusion, it is desirable for beauty-related organizations and professionals to positively develop program of health education with much concern as well as to lessen stress of beauty artists through education of job posture and rightful life in order to prevent lumbago of those beaut.
