바쁜 일상에 주위를 둘러볼 시간적 여유가 없는 도시인이라도 잠깐 눈을 돌려보면 주위에 다양한 식물들의 색다른 모습을 즐길 수 있다. 자귀나무는 가로수나 정원수로 많이 심지만 그리 많이 알려진 식물이 아니다 보니 그냥 지나치는 경우가 많다. 하지만 자귀나무에 대해 조금만 관심을 기울이면 그 매력에 푹 빠지게 된다.

현대사회의 복잡한 생활환경과 더불어 주위의 밀폐공간에서 발생한 소음은 인접한 환경에서 커다란 영향을 미치고 있다. 그러므로, 본 연구에서는 밀폐공간의 음향특성을 연구하고, 또한 밀폐 공간에서 발생된 소음원이 주위의 생활환경에 미치는 영향을 최소화할 수 있는 밀폐공간의 크기를 연구하였다. 연구한 결과, 길이를 변화시킴으로써 우리가 주목해야할 주파수의 모우드 분포를 고려하여 최적한 크기를 결정할 수 있었다.

원자로 노심내 핵 연료봉의 정확한 온도 분포를 구하기 위해서는 핵 연료봉 주위의 난류 유동장에 대한 해석이 필요하다. 난류 유동장의 특성을 파악하기 위해 실험적 연구와 해석적 방법에 의한 연구가 함께 수행되고 있다. 본 기고문은 현재까지 보고된 난류 유동장의 특성을 알아보고 해석적 방법의 연구 동향과 문제점을 분석하여 이 분야에 대한 연구 활동에 도움이 되고자 한다.

인터넷 커뮤니티나 개인적 친분을 이용하여 타인의 HIV감염 사실을 공개적으로 밝혀 문제가 되고 있다. 아웃팅(감염사실을 공개적으로 밝히는 일)당한 감염인들은 감염사실이 주위에 알려지면서 친구를 잃고, 직장을 잃는 등 심각한 피해를 겪고 있다. 후천성 면역결핍증예방법에서 간과하고 있는 직무와 무관한 사람에 의한 감염사실 공개에 대하여 엄숙한 법적 제재가 가해져야 할 것이다.

The purpose of this study was to compare acute and chronic LBP patient in twenties and forties, respectively by size measure paraspinal muscle (cross-sectional area; CSA). CSA of paraspinal muscle (psoas, multifidus, erector muscle) size was measured by free-handling technique of the picture archiving and communication system(PACS) using MRI at the level(lower end-plate of L4) in twenties(9 males, 10 females) and forties(9 males, 8 females) in acute and chronic LBP patient. The results of this study showed no significantly difference between acute and chronic LBP (p>0.05) in twenties patients. However, there was significant difference between acute and chronic LBP (p<0.05) in forties patients. Also, there was significant difference in paraspinal muscle CSA between chronic LBP patients in twenties and chronic LBP patients in forties (p<0.05). This study showed that paraspinal muscle atrophy was observed in forties with various cause, but Not chronic LBP patients in twenties. Accordingly it is required for chronic LBP patients in forties to minimize trunk muscle atrophy through immediate back muscle dynamic exercise and early functional activity.

Purpose: To evaluate the incidence of deep vein thrombosis (DVT) before hip fracture by duplex color Doppler ultrasonography. Materials and Methods: From June 2013 to May 2014, 27 patients who had agreed to perform color Doppler ultrasonography before hip fracture surgery were evaluated for the incidence of DVT. Patients who had history of DVT were excluded. Five patients were men and 19 patients were women. The mean age was 74.3 years old (41-87). There were 15 cases of femoral neck fracture, 11 cases of intertrochanteric fractures and one case of acetabular fracture. Surgical intervention underwent within 48 hours from admission and duplex color Doppler ultrasonography was carried out at the day of admission. Results: DVT occurred in six cases (22.2%). Four cases (14.8%) occurred in proximal deep vein and two cases (7.4%) occurred in distal deep vein. The mean period of immobilization was longer in patients who had DVT. But there was no significant difference. The mean age was 79 years old (75-87) in patients who had DVT and 72 years old (65-86) in patients who had not. There was significant difference (p=0.038). Conclusion: The incidence of DVT which was diagnosed by duplex color Doppler ultrasonography before hip fracture surgery was relatively high (22.2%). So it is necessary to undergo duplex color Doppler ultrasonography more aggressively to rule out DVT before hip fracture surgery.

Purpose: We performed quantitative and qualitative analysis of typical periodontal bacteria using real time PCR method to investigate the microbiological difference according to the severity of peri-implant disease in Koreans. Materials and Methods: Total of 60 implants were divided into three groups (healthy group, peri-implant mucositis group, peri-implantitis group) through periapical radiographs and clinical indices. The evaluated clinical parameters were pocket depth, plaque index, suppuration and bleeding on probing. Using a sterilized curette instrument, microbial samples were collected from the subgingival plaque and real-time PCR was performed on five periodontal bacteria. The relative expression levels of microorganisms were compared by comparative delta-CT method. Results: The relative expression levels of E. corrodens and T. denticola were significantly higher in the peri-implantitis group (P < 0.017). On the other hand, the relative expression level of F. nucleatum and P. gingivalis was relatively high in the healthy implant group regardless of the severity of disease. P. intermedia was significantly lower in the healthy implant group (P < 0.017). Conclusion: Periodontal bacteria were detected in Koreans with peri-implant diseases, but there was no microbiological distribution similar to periodontitis.

Purpose : A cyst-like lesion within and around the knee joint is very rare, with very few articles available in the literature. The aim of this study is to evaluate effectiveness of arthroscopic treatment of cyst-like lesion within and around the knee joint which reported rarely. Materials and Methods : We are reporting 14 cases of cyst-like lesion around the knee joint. Our cases include 3 ganglion cyst in infrapatellar fat pad, 1 fibroma, 1 giant cell tumor and 1 epidermoid cyst which have not yet been reported. The diagnosis of cyst-like lesion in Juxta-articular knee Joint was made only by MRI study and we confirmed pathology. Male was 9, female was 5 cases, average age was 24(11-43)year old. Follow up was average 45(12months-8years)months. Minimum follow up was 12 months. Results : All the patients were treated arthroscopic excisional debridements successfully. All the cases were excellent result in last follow up by functional criteria in Lysholm knee score average 98.9(95-100). All examimation was normal except 3 cases in last follow up. But all patients satisfied in arthroscopic treatment. Conclusion : Arthroscopic excisional debridement of the cyst-1ike lesion in juxta-arthcular knee joint is excellent method, but long term follow up needed in the future.

Paravalvular abscess is defined as infective necrosis of the mitral annulus and surrounding tissue that requires debridement of the necrotic tissue and patch reconstruction before valve implantation. Paravalvular abscess is associated with high operative mortality, postoperative complications, and recurrence. We report here a case of a 59-year old woman that had undergone mitral valvular replacement with a mechanical valve 13 years ago. The patient was determined to have paravalvular leakage due to paravalvular abscess as seen during follow-up. The patient underwent repeat mitral valvular replacement with annular reconstruction. However, the patient with mitral annular reconstruction and valvular replacement on the fifteenth postoperative day due to recurrence of paravalvular leakage. The patient is now receiving follow-up eight months after surgery.
