This is a clinical study on 235 inpatients who sustained a total of 350 mandibular fractures and who were treated in our department during the period of Oug., 1989 through Dec., 1993. The results obtained are as follows : 1. The mumber of patients has not been increased year after year. In respect of incidence, there were the highest frequency as 67 patients(28.5%) in 1991 and the least frequency as 16 patients(6.8%) in 1989 and the highest frequency as 28 patients(11.9%) in October and the least frequncy as 12 patients(5.2%) in February. 2. The age frequency was the highest in the second decade(30.6%). The youngest patient was 8 months and the eldest patient was 80 years and mean age was 27.8 years. The ratio of men to Wemen was 4 : 1. 3. The most frequent cause was fall down as 86 patients(36.6%) and the next was fist blow 4 as 75 patients(31.9%), traffic accident as 56 patients(23.9%) in order. 4. The most common location was symphysis as 141 numbers(40.3%) and the next was condyle as 96 numbers(27.4%), angle as 94 numbers(26.8%), body as 14 numbers(4.0%) in order. The sum of fracture sites were 350 and there were 1.49 fracture sites per one patient and multiple fractures occured in 100 patients(40.5%) of the 235 patients. The ratio of Left to Right except for symphysis was 1.71 : 1. 5. Among the 333 associated injuries, facial laceration was 136(57.9%) and tooth injury was 58(24.7%) and extremity was 31(13.2%). 6. Among the 350 mandibular fractures, complications after treatment occured in 51(14.6%) and infection as 20(5.7%) was the most frequent complication. 7. In respect of treatment of mandibular fracture, close reduction was 64 patients(27.2%) and open reduction was 164 patients(69.8%) and other were 7 patients(3.0%) of all and so open reduction was the most common in type of treatment.

인공지능 기술은 대상과 학습 단계에 따라 다양한 방법으로 적용할 수 있다. 본 논문에서는 인공지능 기술의 교육적 활용에 관하여 비교 분석하였다. 대상은 교수자와 학습자로 구분할 수 있으며 학습 단계는 학습 전, 중 후로 구분할 수 있다. 향후 학습자의 사고가 담긴 문장 형태의 서술형 답안에 대한 평가 과정을 포함한 시스템을 개발하고 성능향상을 위한 방안을 도출하여 세부적인 실험을 통한 최적화 및 예측 방안을 연구하고자 한다. Artificial intelligence technology can be applied in a variety of ways depending on the target and learning stage. In this paper, we compared and analyzed the educational use of artificial intelligence technology. Objects can be divided into teachers and learners, and learning stages can be divided into before, in, and after-learning stage. In the future, we will develop a system that includes an evaluation process for narrative answers in sentence form containing learners" thoughts, derive measures for performance improvement, and study optimization and prediction methods through detailed experiments.

Actinomycosis is a rare form of disease that is caused by Actinomyces such as A. israelii and A. bovis, which may take the form of chronic, purulent inflammation of deep tissue evolves with necrosis, formation of sinuses and fibrotic mass. This disease arises in the head and neck area mainly in 55% and other places like that chest and the gastrointestinal tract occurs in 45%. Actinomycosis can present in a variety of forms and may mimic other infections or even neoplasms. Our case was 44-year-old man having painful indurated mass in his left TMJ area, otorrhea in his left ear and trismus. He was treated with surgical excision and biopsy confirmed actinomycosis. And after that, he was cured successfully with antibiotic therapy. We report this case of actinomycosis that developed in the left TMJ area with review articles.
