Panoramic radiographs were used to survey the location of the mental foramen horizontally and vertically of the subjects in the deciduous dentition period, early and late mixed dentition period. The results were obtained as follow; 1. Of 103 mental foramen taken, almost the mental foramen were located horizontally between the first and the second deciduous molar.(98.1%) 2. The vertical relative ratio of the distance from the inferior border of the mandible to the upper edge of the alveolar crest through the center of the mental foramen vertically was 0.300 for male subjects and 0.295 for female subjects. 3. The horizontal position of the mental foramen was changed from the anterior position to the posterior postion for aging process. The vertical position of the mental foramen increased from the lower position to the upper position for aging process. 4. The mental foramen of male subjects had a tendency to be located anteriorly and superiorly than that of female subjects. 5. In right and left side, there is no significant difference between the male and female subjects.

The purpose of this research was to identify the effects of the leadership types of the middle and high school golf coaches on the player's maturity by establishing a hypothetical casuality model based on the precedent research. Based on the aforementioned research methods and the data analysis results, the following conclusions were drawn. First, results from analysis of leadership style according to demographic variables of middle school golf players revealed that there were no statistically significant differences in all the variables. Second, results from analysis of differences in leadership style according to demographic variables of high school golf players showed that there were statistically significant differences in training instructions, dictatorial training, and positive feedback accordant with sex. There were also statistical differences in training instructions accordant with the hours of training time per day, and there were statically significant differences in positive feedback accordant with the number of training per week. Third, results from analysis of differences in the player's maturity according to demographic variables of middle school golf players indicated that there were statistically significant differences in the maturity of exercise performance accordant only with the player's golf career. Fourth, results from analysis of the players' maturity according to demographic variables of high school golf players revealed that there were statistically significant differences in psychological maturity accordant with sex, and in the maturity of exercise performance, accordant with school years, and in the maturity of exercise performance, accordant with golf career, and in both the maturity of exercise performance and psychological maturity, accordant with the hours of training time per day, and in psychological maturity, accordant with the number of training per week. Fifth, analysis results revealed that democratic coaching style and dictatorial training had statistically significant influences on the maturity of exercise performance among sub variables of leadership types of middle school golf instructors, and that positive feedback had statistically significant impacts on the psychological maturity. Sixth, the results from analysis of variables indicated that training instructions had statically significant effects on the maturity of exercise performance among the sub variables of leadership types of high school golf coaches, and that positive feedback affected psychological maturity in a statistically significant fashion.

Mandibular movenents which are performed by highly coordinated static and dynamic neuronal networks are basically comprised of posion and movement. Mandibular movements were evoked with natural food ingestion or cerebral cortical stimulation in the normal or experimental animals. They were analized by jaw movement tracking system and emg machine. According to the present data, mandibular movement patterns and each parameter revealed similar tendencies during food ingestion or cerebral cortical stimulation in the normal animals. But cerebral cortical stimulation of the cerebellar cortical destructed rabbits revealed reduced gaping and increased occlusal phase. And the changes after termination of powerful cerebral cortical input in the cerebellar cortical destructed rabbit revealed increased masticatory stroke, remarkedly increased opening phase, increased duration of digastric muscle activity, and increased interval time between masseteric musele activities. These seemed to be resulted from disharmonized temporal and spatial integration due to loss of cerebellar cortical integration. So it is suggesed that cerebellum has a modulating role between peripheral and central information in the stomatognathic system.

This study purposes to find out the relationship between role awareness and self-realization according to the types of golf instructors. To do this, I made analyses on three point---the difference between role awareness and position satisfaction in accordance with the social and demographic characteristics of golf teachers, the difference between role awareness and position satisfaction under the qualified types of golf teachers, and finally the influences to position satisfaction by the role awareness of the golf teachers. The study was surveyed on 250 golf teachers in indoor or outdoor golf rages or sports centers in Seoul and Gyeonggi Province by a random cluster sampling and actually used data were from 228 respondents excluding 22 persons who were considered to respond insincerely or omit some parts. The statistic analysis methods used in the study are correlation and regression. I finally got the following results in this study through the data analysis from the above-stated methods and procedure. among the influential factors which role awareness gives to position satisfaction, it shows the significant level at 5 percent in role conflicts in fellowship, working environment, and payment, in vague roles in fellowship, working environment, payment and promotion and the excessive roles in work itself. working environment, and promotion. In the case of position satisfaction, it showed description 69.0%(R^2=.690) in role conflict, 73.6%(R^2=.736) in vague roles, and 49.3%(R^2=.493) in excessive roles.

The purpose of the study was to determine the ability of the caries activity test, 'Cariostat' to identify preschool children with dental caries. The subjects of this study were 76 children of 3 to 5 years of age. Oral examination was carried out to assess the caries experience using a mirror and explorer. In all subjects buccal plaque samples were obtained, incubated, and scored as the manufacturer's instructions for the Cariostat test. Statistical analyses were used with the Crosstabulation. The test group exhibited mean dft index 5.21, while 27.63% of subjects were caries free and had no restorations. The sensitivity of the Cariostat test was found to be 98.8% while the specificity was found to be 19.05% The results showed that caries activity measured by visual reading was highly significant to the Cariostat score and dft index(P<0.001). The Cariostat method has indicated the future possible occurrence of caries. The use of this method is meant to require in the caries prevention program.
