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.

본 연구는 유치원을 이용하는 부모들을 대상으로 방과후과정과 특성화활동 이용 현황을 살펴보고, 그 결과를 토대로 효과적인 정책 개선 방안을 제안하는 데 그 목적이 있다. 693명의 부모를 대상으로 면담원이 부모와 대면 면담조사를 실시하였고, 수집된 자료는 백분율, 평균과 표준편차 등을 이용하여 결과를 산출하였다. 먼저 방과후과정 이용현황을 조사한 결과를 보면, 첫째, 방과후과정 이용에 따른 추가 부담 지출 비율이 전체 조사 대상의 약 38.2%이며, 추가 비용의 평균액은 약 62,850원이었다. 비용부담과 만족도를 5점 만점 기준으로 볼 때, 보통수준으로 나타났다. 둘째, 방과후과정 참여 이유로는 부모의 맞벌이, 자녀가 친구들과 시간을 함께 보내게 하고 싶어서 등과 같은 순으로 나타났다. 다음으로 방과후특성화활동 이용 현황을 살펴본 결과는 다음과 같다. 첫째, 방과후특성화활동 이용 유아 비율은 조사 대상의 약 68.2%이며, 그 중에서 비용 지출 유아는 약 79.0%, 평균 이용 개수는 약 2.69개이며, 평균 비용은 83,540원으로 조사되었다. 둘째, 선호하는 교육프로그램은 영어가 압도적인 비율로 높게 나타났으며, 자녀들이 활동을 좋아해서 참여한다고 응답한 비율이 가장 높았다. 셋째, 방과후특성화활동 개선요구 사항으로는 교육내용의 내실화가 1순위로 제시되었다. 마지막으로 방과후특성화활동으로 인해 부모의 사교육비 지출이 감소되었다는 응답비율이 높게 나타났다. 이와 같은 조사 결과를 토대로 방과후과정 및 특성화활동 성격에 맞는 적합한 교육프로그램 개발 및 실행 등의 개선 방안을 논의하였다.

이 연구는 방과 후 수업에서 근접발달영역을 고려한 수업이 중학교 1학년 학생들이 학생들의 학습태도와 문제해결력에 미치는 영향이 어떠한지를 알아보기 위하여 디자인 되었다. 연구문제를 해결하기 위하여 방화 후 수업에서 함수를 학습할 때 근접발달영역을 고려한 지도와 일반적인 수업을 받은 학생들에 대하여 학습태도와 문제해결력이 차이를 보이는지 알아보기 위하여 t-검정을 실시하였다. 검정 결과 방과 후 수업에서 근접발달영역을 고려한 수업이 학습태도와 문제해결력에서 유의미한 차이를 보였다.

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.

After-school activities were examined for 449 rural children in first through seventh grades. Childrens engagement of after-school activities were significantly different by child and family characteristics, especially childrens age and behavior control ability. Findings showed a decline in amount of time spent studying and reading and a raise in going to a game-room. Childrens school achievement, emotional and social development were also differed by a range of after-school activities. Children spent more time in studying and reading showed higher grades, happiness, school life. Teachers reported greater aggressive behavior and less adjustment of school life among children participating more in game related activities and hanging out. Watching TV, doing house chores and visiting friends were not variables which showed different outcomes.

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. Elementary school students need more systematic and continual AIDS health education.

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.

This study investigated relationships between the after-school extracurricular activities of kindergarten children and their daily stress. The subjects were 380 kindergarten children; they were interviewed regarding the degree of their daily stress. Their mothers completed questionnaires on the children's extracurricular after-school activities. Statistical analysis of the data showed that kindergarteners who participated in extracurricular after-school activities showed a higher degree of daily stress than children who did not. It was concluded that developmental appropriateness of extracurricular activities should be considered, and educational curricular and strategies to help children cope with daily stress due to excessive extracurricular activities should be prepared. Further research on this subject is recommended.
