Purpose : To demonstrate the radiologic characteristics of the pelvic actinomycosis. Materials and Methods : We retrospectively reviewed the radiologic findings of seven patients with pathologically proven pelvic actinomycosis and analyzed the anatomical location, characteristics of the lesion and alteration of surrounding structures. Results : The location of the lesions were the ovary and adnexa(n = 4), rectum(n = 1), cecum and terminal ileum(n = 1), and bladder(n = 1). Three of the seven patients had a past history of intrauterine devices. Post-contrast enhanced CT showed an ill-defined mass with inhomogeneous enhancement and a tendency to invade the surrounding normal tissue plane. Conclusion : Pelvic actinomycosis should be included in differential diagnosis when an unusually aggressive infiltrative mass is located in the pelvic cavity, especially in a patient with long-term use of intrauterine contraceptive devices.

목적: 슬관절 전치환술 후 발생한 인공관절 치환물 주위 골절의 발생률과 위험인자를 분석하고자 하였다. 대상 및 방법: 1999년부터 2006년까지 퇴행성 슬관절염으로 슬관절 전치환술 시행 후 36개월 이상 추시 가능하였던 596명 951예의 환자를 대상으로 하였다. 인공관절 치환물 주위 골절이 발생한 군을 I군, 대조군을 II군으로 나누어 술 전, 술 중, 술 후 위험인자를 분석하였다. 결과: 슬관절 전치환술 후 인공관절 치환물 주위 골절의 발생률은 2.25%이었고 남자 3예 (14.28%), 여자 18예 (85.72%)였다. 술 전 인자는 고령 (p<0.01, odd ratio=1.14), 골다공증 (p=0.01, odd ratio=4.74), 재치환술 (p=0.01, odd ratio=7.46), 뇌혈관질환(p=0.02,odd ratio=8.55), 알코올 중독 (p=0.03,odd ratio=44.54)이, 술 중 인자는 대퇴 전방절흔 (p<0.01, odd ratio=11.74)이, 술 후 인자는 중노동 (p<0.01, odd ratio=8.14)이 유의한 결과를 나타냈다. 결론: 대퇴골 원위부 인공관절 치환물 주위 골절의 위험인자로 고령, 골다공증, 재치환술, 실족과 낙상에 영향을 주는 동반질환과 대퇴전방절흔, 술 후 중노동의 지속으로 나타났다. Purpose: To evaluate the incidence rate and risk factors for periprosthetic fracture after total knee replacement (TKR). Materials and Methods: We carried out a retrospective case-control study of 596 patients (951 knees) who underwent TKR between 1999 and 2006 and who were followed up over 36 months. We classified patients into group I (study group) and group II (control group). We subdivided risk factors as pre-operative, intra-operative, and post-operative factors. Age, osteoporosis, revision arthroplasty, CVA, and alcohol dependence were categorized as pre-operative factors; anterior femoral notching and prosthetic types (mobile, fixed, and load-bearing) were considered intra-operative factors; and post-operative activity level was classified as a post-operative factor. We obtained information from the patients` charts, X-ray film, and telephone interviews. Results: The overall incidence rate was 2.25%; 3 patients were male, and 18 were female (14.28% and 85.72%, respectively). Old age (p<0.01, odds ratio=1.14), osteoporosis (p=0.01, odds ratio=4.74), revision arthroplasty (p=0.01, odds ratio=7.46), CVA (p=0.02, odds ratio=8.55), and alcohol dependence (p=0.03, odds ratio=44.54) were statistically significant among the pre-operative factors. Among the intra-operative factors, anterior femoral notching (p<0.01, odds ratio=11.74) was significant, and continued heavy labor (p<0.01, odds ratio=8.14) was significant among the post-operative factors. Conclusion: We concluded that old age, osteoporosis, revision arthroplasty, comorbidity related with falling down, anterior femoral notching, and continued heavy labor were associated with periprosthetic fracture after TKR.

신주용(Shin Ju Yong),황의홍(Hwang Eui Hong),이장수(Lee Jang Soo),권영우(Kwon Young-Woo) 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.6

CrowdQuake는 MEMS 가속도 센서를 기반으로 하는 지진 관측망으로, 약 1년 동안 운영되며 지진을 관측하였다. 시스템에 사용 중인 2300여 개 가속도 센서에서 5일간 매일 자정 한 시간 데이터를 이용해 분석한 결과 약 1.5%에 해당하는 34개의 센서를 제외한 거의 모든 센서가 정상 동작함을 파악하였다. 실제 지진을 분석한 결과로는 2월 15일군산 지역에서 발생한 지진은 실제 진앙과 근사한 위치를 추정하는 것을 볼 수 있었다. 하지만 4월 19일 흑산도 인근 해역에서 발생한 지진은 현재 시스템이 진앙을 추정하는 방식의 문제로 인해 진앙지 결정이 어렵다는 점을 확인하였다. 향후 연구로 가속도 센서를 활용한 시스템에서 정확한 진앙지 추정을 할 수 있는 알고리즘에 대해 연구하고 적용하여 CrowdQuake의 지진 감지 성능을 향상하고자 한다.

Objectives: The purpose of this study is to investigate the difference in the effects of eye-mask and light-off on sleep status according to a commercial fitness tracker and a sleep diary of psychiatric in-patients in correctional facilities where nocturnal light is compulsory. Methods: This study was conducted over 3 consecutive nights. In-patients of the National Forensic Psychiatric Hospital (n = 29) were assigned random subject numbers and slept as usual in the light-on condition on the first night. The subjects slept with eye-masks in the light-on condition on another night and without an eye-mask in the light-off condition on the other night. Subjects were asked to sleep wearing a commercial fitness tracker and to keep a sleep diary. The order of these changes in bedroom lighting condition on the second and third nights was assigned randomly to participants. Results: In comparison of the sleep variables between the light-on condition and the eye-mask condition, the Wakefullness After Sleep Onset (WASO) was shorter and sleep satisfaction was higher in the latter.(respectively, Z = 3.66, p < 0.017 ; Z = 2.69, p < 0.017) In comparison of the sleep variables between the light-on and light-off conditions, the WASO was shorter and sleep efficiency and sleep satisfaction were higher in the latter (respectively, Z = 2.40, p < 0.017 ; Z = 3.02, p < 0.017 ; Z = 3.88, p < 0.017). However, there were no differences in the sleep variables between the eye-mask condition and the light-off condition. Conclusion: Subjective improvements in sleep variables were noted in sleep diaries of institutionalized psychiatric patients under either the ‘eye-mask’ or ‘light-off’ condition. However, there were no significant differences between the ‘eye-mask’ and ‘light-off’ conditions. Therefore, we suggest that psychiatric patients in correctional facilities use eye-masks when sleeping.

Purpose: To compare the results of a total knee arthroplasty (TKA) between the degenerative osteoarthritic patients and the posttraumatic arthritic patients. Materials and Methods: 38 cases with posttraumatic arthritis (group A) and 40 cases with degenerative osteoarthritis (group B) had a total knee arthroplasty between April 1995 and May 2002. The knee score, functional score, activity level and radiologic analyses were performed. Results: There were no significant difference in the knee score, functional score, activity level and radiological findings between the two groups. The range of motion arcs were reduced in the posttraumatic arthritic patients. There is a higher complication rate in the post-traumatic arthritic patients (36%) when compared with the degenerative osteoarthritic patients (15%) after TKA. Conclusion: In group A showed a higher complication rate and reduced range of motion arcs. However, in terms of our results, we considered that a total knee arthroplasty is an useful treatment for the posttraumatic arthritis in spite of the technical difficulties.

Purpose: We evaluated the polyethylene wear rate between patients from farming and non-fanning communities to determine whether active life styles, knee scores, and occupations could affect outcomes. Materials and Methods: 201 knee replacements were performed in 105 patients who were an average of 68.7 years old. 30 non-farming patients (59 cases) and 75 fanning patients (142 cases) who had operation between 1989 and 1996 were reviewed retrospectively. Mean follow-up period was 12.1 years (range 10~16 years). The difference of clinical, radiographic, and functional results of total knee replacement were assessed by Knee Society scores and activity levels. Results: The non-fanning group had lesser activity levels (non-fanning group 82.5, fanning group 89.7), higher knee scores (non-farming group 88.4, farming group 81.1) and functional scores (non-farming group 87.9, farming group 80.4) than the farming group (p<0.05). Fanning patients showed 33 cases (23%) of polyethylene wear and non-farming patients showed 7 cases (12%) which is statistically significant (p<0.001). Conclusion: Primary osteoarthritic patients from farming communities had higher activity levels and polyethylene wear rate with lower Knee Society scores which were expected to participate in more activities involving impact on knee joint. We assume that the increase rate of complication is due to the overuse of the prosthesis. Therefore, working condition and life style modification will be needed.

신주용 ( Ju Yong Shin ),김형준 ( Hyeung June Kim ),김응식 ( Eung Sik Kim ),김동헌 ( Dong Heon Kim ) 대한고관절학회 2008 Hip and Pelvis Vol.20 No.3

목적: 고령의 대퇴 경부 골절 환자에 대한 양극성 반치환술 후 추시 관찰한 결과를 분석하여 문헌 고찰과 함께 보고하고자 한다. 대상 및 방법: 1995년 3월부터 2005년 3월까지 75세 이상 대퇴 경부 골절 환자 중, 양극성 반치환술 시행 후 2년 이상 추시가능하였던 186예를 대상으로 하였다. 평균 연령은 84.3(75~99)세였고 남자가 48예(26%), 여자가 138예(74%)였으며 추시 기간은 68.4(24~113)개월이었다. Modified Harris 고관절 점수, 보행능력, 일상 생활 활동력, 합병증, 골다공증 등을 분석하여 임상적 평가와 방사선적 평가를 시행하였다. 결과: Modified Harris 고관절 점수는 89.2(74~95)점이었고 보행시작 시기는 6.5(3~9)일이었다. 163예(87.6%)에서 수상 전보행능력을 회복하였으며 159예(85.4%)에서 수상 전 일상 생활 활동력이 가능하였다. 비구컵의 전이 3예, 무균성 해리 3예가 시멘트형 주대에서 발생했고, 대퇴부 동통은 시멘트형 주대 8예, 무시멘트형 주대 4예에서 발생하였다. 결론: 고령의 대퇴 경부 골절 환자에 시행한 양극성 반치환술은, 추시 결과상 안정된 주대 및 견고한 골절부 고정으로 조기보행, 합병증 감소와 낮은 사망률을 나타내므로 적절한 주대 선택과 숙련된 기술로 시행된다면, 골다공증과 분쇄 골절이 심한 고령의 환자에 유용한 치료방법으로 사료된다. Purpose: To evaluate outcomes after treatment of femoral neck fractures in patients 75 years of age or older. Materials and Methods: We reviewed the records of 186 patients 75 years of age or older who underwent bipolar hemiarthroplasty between March 1995 and March 2005 and who were followed for more than two years after surgery. The mean patient age was 84.3 years (range 75~99 years). Forty-eight patients were men, and 138 patients were women. The mean follow-up period was 68.4 months (range 24~113 months). We evaluated the results by analyzing modified Harris hip score, walking ability, activities of daily living, complications, osteoporosis, and radiologic findings. Results: The mean Harris hip score was 89.2 (range 74~95). Walking ability was recovered in 87.6% of cases (163 cases), and activities of daily living were achieved in 85.4% of cases (159 cases). There were 3 cases of acetabular erosion or proximal migration and 3 cases of aseptic loosening in a cemented stem. Thigh pain occurred in 8 cemented stems and in 4 cementless stems. Conclusion: We believe bipolar hemiarthroplasty is a useful treatment in elderly patients with femoral neck fractures and severe osteoporosis, especially in view of the stable and rigid fixation of the femoral stem, early ambulation, and the low rate of complications and death, even if the operation is technically very difficult.
