Purpose: This study evaluated the prognosis of conservative and surgical treatment according to the staging of bisphosphonate-related osteonecrosis of jaw (BRONJ) by American Association of Oral and Maxillofacial Surgeons and American Society for Bone and Mineral Research. Methods: We evaluated 53 patients of BRONJ who visited Department of Dentistry, Ajou University School of Medicine from May 2007 to February 2013. Twenty eight patients in stage 2, were divided into surgical and conservative groups with cessation of bisphosphonate therapy. Fifteen patients belonged to the conservative treatment group, in which mouth rinsing and antibiotics medication were done. Thirteen patients were treated with debridement or sequestrectomy, in the surgical treatment group. Each study list was analyzed by SPSS ver. 14.0 (SPSS Inc., USA) software and the favorable rate was verified by the Fisher exact test. P-values less than 0.05% were deemed significant. Results: Clinical outcome was evaluated on the basis of both clinical and radiographic findings. Of all the 28 patients of stage 2, 15 patients underwent conservative treatment and 13 patients received surgical treatment. In the surgical group, 9 of 13 (69.2%) showed good prognosis, 4 of 13 (30.7%) showed recurrence. In the conservative group, 13 of 15 (86.6%) showed no change duting the follow-up period. Two of 15 patients even showed a bad prognosis, such as pain and pus discharge, which are criteria for stage 3. P-value was 0.067 (>0.05). Conclusion: The results of the present study suggests that surgical intervention is good choice against the conservative treatment, after proper drug holidays period, while further investigation is needed for a definite solution to BRONJ.

Purpose: The purpose of this study was to evaluate the feasibility of the outfracture osteotomy sinus graft technique with the evaluation of 8.5 year survival rate of the implants placed in the atrophic edentulous posterior maxillary area. Methods: One hundred and seventy-six cases of 145 patients who visited our center from August 2004 to February 2013 and were diagnosed as atrophic edentulous maxillary alveolar ridge, were selected and underwent sinus graft with outfracture osteotomy sinus graft technique. Feasibility of the outfracture osteotomy sinus graft technique was investigated with clinical and radiographic evaluation to assess the survival rate of the total dental implants in augmentation sinus surgery. Total fixture number available in follow-up period was 320, in which the lost 15 patients were excluded out of 160 patients. Results: Eight point five year cumulative survival rate was 95.6% with 14 failures of total 320 fixtures. The average follow-up period was 28 months 16 days with the minimum and maximum follow-up periods of 4 months 5 days and 94 months 10 days, respectively. Conclusion: Traditional infracture technique is a popular method for an augmentation sinus surgery. The authors modified this classical method by outfracturing and readapting the bony window after sinus graft, with excellent treatment results evidenced by high survival rate, which proves the feasibility of the newly-designed outfracture osteotomy sinus graft technique.
학교모래놀이 집단상담이 초등학생의 정서·행동 문제, 또래 문제, 공격성에 미치는 효과

본 연구는 초등학생 집단을 대상으로 정서·행동 문제, 또래 문제, 공격성 측면에서 학교모래놀이 집단상담의 효과를 알아보고자 하였다. 아산시 소재 A초등학교 재학중인 3학년 20명(남11, 여9)을 연구대상으로 선정하였으며 2019년 9월부터 11월까지 12주 동안 총 10회의 집단상담을 실시하였다. 집단상담의 효과검증을 위해 한국어판 강점 난점 설문지(SDQ-Kr), 공격성 척도(AQ)를 측정도구로 사용하였으며 SPSS 21.0 프로그램을 사용하여 paired t-test를 실시하고 효과크기를 산출하였다. 분석 결과 품행문제, 또래문제, 총난점, 신체적 공격성, 언어적 공격성, 분노감, 적대감 척도가 유의하게 감소하였고 품행문제, 또래문제, 언어적 공격성, 분노감 척도는 큰 효과크기를 나타냈다. 이러한 결과는 학교모래놀이 집단상담이 초등학생들의 정신건강과 또래문제 개선에 효과적인 방법일 수 있음을 시사한다. This study investigates the effect of school sand play group counseling in terms of emotional and behavioral problems, peer problems, and aggression for elementary school students. 20 students from A Elementary School in Asan-si were selected as subjects of the study, and a total of 10 group consultations were conducted for 12 weeks from September to November 2019. In order to verify the effectiveness of group counseling, the Korean Version of the Strengths and Difficulties Questionnaire (SDQ-Kr) and the Aggression Question naire (AQ) were used as measurement tools, and the paired t-test was performed using the SPSS 21.0. As a result of the analysis, behavior problems, peer problems, total difficulties, physical aggression, verbal aggression, anger, and hostility scales were significantly reduced, while behavior problems, peer problems, verbal aggression, and anger scales showed great effects. These results suggest that group counseling for school sand play may bean effective way to improve mental health and peer problems of elementary school students.

고강도 철근콘크리트 부재의 경우 일반콘크리트에 비해 시공성이 낮으며, 품질관리의 어려움, 화재시 고온으로 인한 내화성능 저하로 인해 구조 안전성이 요구되는 실정이다. 이것은 고강도 콘크리트의 파괴양상이 매우 취성적이며, 국부적인 파괴를 일으키기 때문이다. 콘크리트의 파괴를 일으키는 원인으로서는 전단철근비, 인장 철근비, 전단경간비, 콘크리트 압축강도, 보의 폭 대 깊이 비 등이 있으며, 이들은 서로 상호복합작용으로 인하여, 콘크리트 전단강도의 정확한 전단설계값 및 파괴를 예측하지 못하므로 기존의 전단강도 식들은 충분한 안전율을 확보하기 위하여 보수적인 값을 제시하고 있다. 본 연구에서는 고강도 철근콘크리트보의 전단강도 특성을 연구하기 위해 콘크리트압축강도( = 50 MPa), 인장철근비(ρ=0.025) 및 폭 대 깊이비(h/b)를 일정하게 하였으며, 보의 크기(b×d)와 전단철근간격(d/s)을 변수로 한 12개의 시험체를 제작하여 실험을 하였다. 시험체는 단면의 크기에 따라 SHR1, SHR2, SHR3으로 된 총 3개의 시리즈로 나누었으며, 각 시리즈 당 전단철근의 간격에 따라 4개씩 총 12개의 시험체를 제작하였고, 시험체의 전단파괴를 유도하기 위하여 전단경간비는 2.5로 하였다. 실험값에 대한 여러 기준식 및 제안식과의 비교를 한 결과, 평균값은 1.15 ~ 1.60, 표준 편차는 0.13 ~ 0.18로 나타났다. 여러 기준식 및 제안식들 중 실험값을 비교적 잘 예측하고 있는 것은 Zsutty, Bazant, Lee 식이다. Zsutty 방정식의 평균은 1.29, 표준 편차 0.16, Bazant 방정식의 평균은 1.15, 표준 편차는 0.17, Lee 방정식의 평균은 1.17, 표준 편차는 0.18로 나타났다.
