Tooth extraction after head and neck radiotherapy exposes patients to an increased risk for osteoradionecrosis of the jaw. This study reports the results of a radiographic analysis of bone neoformation after tooth extraction in a case series of patients who underwent radiation therapy. No patients developed osteoradionecrosis within a follow-up of 1 year. Complete mucosal repair was observed 30 days after surgery, while no sign of bone formation was observed 2 months after the dental extractions. Pixel intensity and fractal dimension image analyses only showed significant bone formation 12 months after the tooth extractions. These surgical procedures must follow a strict protocol that includes antibiotic prophylaxis and therapy and complete wound closure, since bone formation at the alveolar socket occurs at a slower pace in patients who have undergone head and neck radiotherapy.

First of all, the results of after-school are presented. First, about 38.2% of the surveyed parents spent additional expenses to use after - school program, and the average of additional costs was about 62,850 won. When the cost burden and satisfaction were evaluated as 5 points, it was rated as normal.

This study explored pathways from mothers' beliefs to children's subjective well-being through children's private after-school activities and stress levels. A sample of 230 6th grade elementary school students (125 boys and 105 girls) in Seoul completed questionnaires on children's stress and subjective well-being. Their mothers responded to questionnaires on mothers' beliefs and children's private after-school activities. Data were analyzed by means of Pearson's correlation coefficients and multiple regression analyses. Our results demonstrated that mothers' beliefs indirectly influenced children's subjective well-being through both children's private after-school activities and stress levels. Neither children's private after-school activities nor children's stress mediated between mothers' beliefs and children's subjective well-being. Mothers' beliefs also had a direct effect on children's subjective well-being. Significantly, both mothers' beliefs and children's stress played crucial roles in improving children's subjective well-being.

This study examined changes of elementary school students' knowledge and attitudes toward AIDS after AIDS health educational programs were conducted. The experiment was executed from November the 28th, 2001 to February the 6th, 2002. Study examinees were 156 fifth year students of 2 elementary schools located at S City. A preliminary inspection was implemented. The post-examination was conducted by a questionnaire survey 2 weeks and 9 weeks after the program was finished. The measurement instrument was the questionnaire developed by Yun, Hyun Sik(1997) and modified by this researcher. Collected data were analyzed with SPSS program package, $x^2$-test and t-test, Repeated Measure ANOVA. Findings of study are as follows; 1. Hypothesis 1 ; the hypothesis 1 is "The points of AIDS knowledge are different at each moment, before conducting the educational program, 2 weeks after conducting the educational program, and 9 weeks after conducting the educational program". After the above hypothesis was examined, interactive actions were shown among different periods in both groups (F=267.241, p=.000), so that this hypothesis 1 was approved. 2. Hypothesis 2 ; the hypothesis 2 is "The points of attitudes toward AIDS are different at each moment, before conducting the educational program, 2 weeks after conducting the educational program, and 9 weeks after conducting the educational program". It was closely examined, and the findings are that significant differences between two groups were found, whereas any interactions were not shown between two groups(F=3.753, p=.055), after controlling the attitude scores that showed differences before the education by covariable, and examining the results. so that this hypothesis 2 was rejected. The above study tells that the AIDS health education for elementary school students made their knowledge and attitudes change significantly, but the education was not effective for changing students' attitudes.

Purpose: The purpose of this study was to examine the appropriate degree of set-back of the mandible by evaluating the rate of relapse after surgery. Methods: Among the patients who visited our hospital from January 2002 to January 2007 and who underwent orthognathic surgery, of the patients available for follow-up observation, the rate of relapse after surgery was investigated according to the set-back degree. The patients were divided into groups by the degree of set-back, and relapse was evaluated by the radiographs performed the day after surgery, 6 months after surgery, 1 year after surgery, 2 years after surgery and 3 years after surgery. Results: In cases that exceeded the limit of posterior movement of the mandible (13 mm) or that had the wrong position of the condyle, a greater tendency toward relapse was shown. Conclusion: Based on the results of this study, among the cases that required a large amount of posterior movement of the mandible, two jaw surgeries accompanied by bilateral sagittal split ramus osteotomy (BSSRO) and LeFort I osteotomy are recommended.
