2011년 3월 11일 발생한 일본 후쿠시마 원전 사고 후 한국 대학생들의 방사선과 의료 방사선에 대한 생각을 파악하여 방사선에 대한 적절한 교육 방법과 국민들의 방사선 안전에 대한 올바른 대중 커뮤니케이션에 대해 모색하고자 전국 5개도(경기, 강원, 충청, 전라, 경상도)의 4년제 방사선학과가 설치된 대학교에서 790부 설문지를 수거한 후 분석하였다. 설문은 36문항으로 구성하였으며, '방사선이 위험하다'고 느끼는 중요 원인 중 하나는 '적은양의 방사선을 쪼여도 나중에 문제가 생길 수 있다'. ($3.28{\pm}1.05$)로 분석됐다. 방사선에 대한 관리에서는 개인보다는 정부가 나서야 된다는 응답자가 $3.87{\pm}0.89$으로 나타났다. '후쿠시마 원전 사고는 원자력 발전을 하지 말아야 한다는 쪽으로 나의 생각을 바꾸게 했다'라는 문항에는 $2.79{\pm}0.95$로 나타났다. '후쿠시마 원전사고 이후 의료 방사선에 대한 생각이 부정적으로 바뀌었다'라는 문항에는 전체적으로 $2.64{\pm}1.02$, 방사선학과 $2.31{\pm}1.00$, 치위생학과 $2.94{\pm}0.95$, 기타학과 $3.13{\pm}0.82$로 방사선과 관련된 교과목을 수강 경험이 없는 기타학과 학생일수록 부정적인 생각을 가지고 있는 것으로 나타났다. 또한 방사선에 관한 교육이 필요하다고 생각하는 사람이 82.28%로 나타났으며, 그 중 T.V나 인터넷이 가장 효율적인 교육 방법으로 나타났다.

Purpose: This study evaluated the clinical applications of implant placement and guided bone regeneration using a mineralized bone allograft and a barrier membrane derived from ox pericardium Methods: From January 2007 to June 2009, among the patients who received an implant at Chosun University Dental Hospital, patients were selected if they were treated with guided bone regeneration (GBR) with simultaneous implant placement or GBR prior to implant placement. The selected patients were sorted according to the materials and membranes used in GBR, and the implant survival rate was recorded by clinical examination and reviewing the medical records and the radiographs. Each study list was analyzed by SPSS (version 12.0, SPSS Inc., USA) software and the survival rate was verified by Chi-square tests. $P$ values less than 0.05% were deemed significant. Results: 278 implants were placed on a total of 101 patients and 8 implants resulted in failure. Three implants failed among 15 implants with only a mineralized bone allograft. No failure was shown among the 74 implants placed with mineralized bone allograft and a barrier membrane derived from ox pericardium. One group of 4 implant placements showed failure among the 102 implants placed with a mineralized bone allograft and another bone graft material. The group that had a barrier membrane derived from ox pericardium with a mineralized bone allograft or other bone materials showed no implant failure. Three failures were shown among the 21 implants placed with only bone graft and not using a membrane. The group with membranes other than a barrier membrane derived from ox pericardium showed 5 failures among 170 implants. Conclusion: The implant survival rate of the group with GBR using a mineralized bone allograft was 96.3%, which meant there was little difference compared to the groups of another bone graft materials (98.9%). The implant survival rate of the group without a membrane-was 85.7% and it showed a significant difference compared to the group using a barrier membrane derived from ox pericardium (100%) and the group using another membrane (97.1%).

Purpose: This study evaluated the prognosis and survival rate of SLA (Sandblasted, Large-grit and Acid-etched) implants and it also evaluated the prosthodontic complications and the associated factors. Methods: Twenty seven patients (14 men and 13 women, mean age: 54.9) who visited Chosun University Hospital Implant Center with the chief desire for placement of an implant in an edentulous area from March, 2008 to December 2008 and who received placement of a SLA implant ($Implantium^{(R)}$, Dentium Co., Korea) were selected for this study. Results: The average follow-up period was 15 months and the study was based on the treatment records, radiographs and clinical examinations. A total of 69 implant cases were retrospectively assessed for the width and length of the implant, the primary and secondary stability, the combined surgery, the employed bone graft material and barrier membrane, the status of the opposing tooth, implant failure and the prosthetic complications. During the follow-up period (average: 15 months), the accumulative survival rate of the 69 implants in 27 patients was 100%. Complications such as infection, sinusitis and fixture exposure after surgery were seen for 5 implants in 4 patients. Complications such as screw loosening, contact loosening and peri-implant gingivitis after prosthodontic treatment occurred in 7 cases (10.14%). Conclusion: This study reports placement of SLA implants may cause various complications, yet the final accumulative survival rate was 100%. The SLA implant ($Implantium^{(R)}$) has an excellent clinical survival rate and outcome.

Introduction: The incidence of bisphosphonate-related osteonecrosis of the jaw (BRONJ) has increased gradually in patients who have undergone surgical treatment for osteomyelitis. In this study, a retrospective analysis of BRONJ patients was carried out using the data of osteomyelitis patients treated surgically. Materials and Methods: Osteomyelitis patients, who underwent curettage, sequestrectomy, saucerization or decortications, and partial mandibulectomy at Seoul National University Dental Hospital from 2004 to 2010 were enrolled in this study. The patients were classified and categorized into two groups based on the surgical records and progress notes. One group comprised of patients with osteomyelitis and osteoporosis, and the other group included patients with osteomyelitis only. The epidemiological data of the BRONJ patients was analyzed to identify any trend in the incidence of BRONJ in osteomyelitis patients. Results: Among 200 patients who underwent surgical intervention for osteomyelitis, 64 (32.0%) were identified as having osteoporosis as the underlying disease. In these 64 patients, more than 81.3% had been prescribed bisphosphonates. Females were far more affected by BRONJ than males. The incidence of BRONJ also increased with age. The posterior part of the mandible was affected more frequently by BRONJ. Conclusion: Although the availability of potent antibiotics and increased oral hygiene care can reduce the overall incidence of osteomyelitis, BRONJ can increase the total incidence. To prevent BRONJ, it is recommended that an oral examination be performed before prescribing bisphosphonates. Moreover, the patients should be educated about the potential risks of dental procedures that might be causal factors for BRONJ. Furthermore, patient swho take bisphosphonates for the treatment of osteoporosis should undergo periodic follow up oral examinations to prevent BRONJ.

The Purpose of this study was to explore the condition of periodic medical examination and the health care services of industries in order to offer some basic data on developing industrial nursing care. To achieve this goal a self - administered questionnaire (developed by the academic affairs of community health nursing) was provieded to the nurses in 56 industries from Dec. 10, 1992 to Jan. 20, 1993. The statistical computer package, SPSS, was used to manipulate the data along with T-test and ANOVA. The results were as follows : 1. General characteristics: The greater part of the industries were manufacturing company, and below 300 employees of industry were 55.4%. The shift system was mostly one shift(66.1%) and three shift(23.2%), and 50.0% them organized the Industrial Safety and Health Commitee. Average a number of employees was 631 person. 2. Periodic Medical Examination: Most of the workers were receiving periodic medical examination from the designated hospital (95.71%). From the about 12.89% were gone through a colse medical examination. In colse medical examination 58.41% were decided 'C' and 36.73% were decided 'D'. About 6.23% off those who had any clinical findings were work-time shortening(7.84%), work-transition(8.12%), recoverating at home. The majority of the workers receive the result of the periodic medical examination individually (78.5%). 3. Special medical examination: The rate of those who are receiving special medical examination were 76.82% and about 8.24% were decided 'C' and 1.23% were decided 'D' Those who had any health problems were receiving follow-up checking (9.10%) and medical treatment while working (15.04%). The health managers in the company can consult (85.7%) those who had any suspicious sign and symptoms of occupational disease. 4. Health care services: The average score of health care services were 17.57 point out of 28 point, and the score was lower in health assessment and environmental hygiene than medical diagnosis and health education. There were significant differences in environmental hygine (F=3.72, P=0.017), health care services(F=3.94, P=0.013) according to the size of the size of the industries The other's significancy is not shown by any type of industrial nurse. The level of health care services were higher in the wokers who had better health and showed no singificant differences(T=-0.73, P=0.470).

CATCH 22 증후군(CATCH 22 Syndrome)은 선천성 심장기형, 비정상적인 안모, 흉선 형성부전, 구개열, 저칼슘혈증을 특징으로 하나 임상양상은 다양하게 나타난다. 본 증례는 치과 검진에 비협조적이고 다수의 치아 우식을 보이는 4세 5개월의 CATCH 22 증후군 환자를 전신마취 하에 효과적으로 치료하였기에 이를 보고하는 바이다. CATCH 22 증후군 환아는 선천적 심장기형을 동반하는 경우가 많아 의과적 자문 하에 치과 치료를 시행해야 한다. 간단한 치료의 경우 의과적 자문 하에 진정법 시행을 고려해 볼 수 있으나 불안정한 생징후를 보일 수 있어 보다 면밀한 모니터링을 요한다. CATCH22 환아의 전신상태에 대한 충분한 이해 및 술전 평가를 바탕으로 한 주의깊게 시행된 전신마취 술식은 다발성 치아우식의 치료에 있어서 보다 안전하고 효과적인 방법이 될 수 있을 것으로 사료된다.
