지난 9월 19일 전남 곡성에서는 2년여의 공사를 마치고 문을 연 곡성섬진강천문대 개관식이 있었다. 곡성섬진강천문대에는 한국천문연구원이 주도하여 제작한 제작한 60cm 반사망원경이 설치되어 있다. 공립천문대 중 순수 국산 기술로 제작된 망원경이 설치된 곳은 이곳이 유일하다.

In general, most knee dislocations are reduced easily by simple traction. In rare cases, closed reduction of the knee dislocation is attempted, but ruptured ligaments or muscles are stuck in the joints and cannot be reduced. The cases of this irreducible knee dislocation have sometimes been reported. The authors encountered a case of irreducible knee posterolateral rotational dislocation that was not reduced by simple traction and report it along with a review of the literature. This case provides an opportunity for clinicians to examine the clinical considerations when experiencing an irreducible knee dislocation.

Objective: This study evaluated the feasibility of ultrasound-guided lumbar nerve root block (LNRB) and S1 nerve root block by identifying spread patterns via fluoroscopy in cadavers. Method: A total of 48 ultrasound-guided injections were performed in 4 fresh cadavers from L1 to S1 roots. The target point of LNRB was the midpoint between the lower border of the transverse process and the facet joint at each level. The target point of S1 nerve root block was the S1 foramen, which can be visualized between the median sacral crest and the posterior superior iliac spine, below the L5-S1 facet joint. The injection was performed via an in-plane approach under real-time axial view ultrasound guidance. Fluoroscopic validation was performed after the injection of 2 cc of contrast agent. Results: The needle placements were correct in all injections. Fluoroscopy confirmed an intra-foraminal contrast spreading pattern following 41 of the 48 injections (85.4%). The other 7 injections (14.6%) yielded typical neurograms, but also resulted in extra-foraminal patterns that occurred evenly in each nerve root, including S1. Conclusion: Ultrasound-guided injection may be an option for the delivery of injectate into the S1 nerve root, as well as lumbar nerve root area.

May-Thurner syndrome (MTS), also known as iliac vein compression syndrome, is a condition, in which compression of the common venous outflow tract of the left lower extremity can cause discomfort, swelling, pain or blood clots in the iliofemoral veins. The problem is due to left common iliac vein compression by the overlying right common iliac artery. This paper describes the case of a 75-year-old female with MTS after performing right total knee replacement arthroplasty. The authors diagnosed MTS through intravenous angiography and angiographic computed tomography on swelling and pain of the left lower extremities after performing right total knee replacement arthroplasty. The thrombus was removed using a thrombolytic agent and mechanical thrombectomy, and an intravenous stent then inserted after angioplasty. No case of MTS after performing total knee replacement arthroplasty has been reported in Korea. Therefore, this case is reported along with review of the relevant literature.

Purpose: In the treatment of Dupuytren's contracture, the aim of optical treatment is to lower the recurrence rate and reduce complications. This paper reports the results of subtotal fasciectomy in Dupuytren's contracture, extending the excision of palmar fascial structures from the diseased to normal appearing adjacent fascial structure. Materials and Methods: From 2007 to 2017, 45 patients with Dupuytren's contracture treated by subtotal fasciectomy were reviewed retrospectively. The mean follow-up period was 45.9 months. Ninety-two digits were involved (index: 2, middle: 10, ring: 44, little: 36). The predisposing factors and affected joint were reviewed and the preoperative and postoperative contracture was measured. For clinical results, quick disabilities of the arm, shoulder, and hand (quick DASH) were used. Complications, including wound or skin problems, nerve injuries, hematoma, and complex regional pain syndrome, were assessed. Results: Preoperative flexion contracture was 43.2° in the proximal interphalangeal joint and 32.9° in the metacarpophalangeal joint. In nine cases, patients had residual contracture of 9.7° (range, 5°-20°) on average and if the total number of cases were included, the mean residual contracture was 2.3° on average. The quick DASH score at the 12 months follow-up was 12.4. The overall complication rate was 26.6%. Conclusion: Subtotal fasciectomy can be a good surgical treatment option for Dupuytren's contracture with a low recurrence and low complication rate compared to other open procedures.

This study traces the growth and changes in the spatial distribution and characteristics of media cluster in Seoul by focusing on the co-evolution of film and TV production. To identify the spatial distribution and aggregation of film and broadcast TV production, we measure their spatial auto-correlation based on Moran's I and LISA, using the data from the Census on Establishments of the National Statistical Office. In addition, the eleven semi-structured interviews conducted with workers in the media industries, such as film crews and TV drama producers, help to clarify the complexity and dynamics of diverse factors that affect spatial distribution of media cluster. This multi-method study shows the increasing polycentricity of media cluster in the last decade. Gangnam, Mapo, Yeouido, Gangseo-Yeongdeungpo, and Seongsu have emerged as key hubs for media industries, particularly in light of changes in the transportation system and the real estate market. The finding indicates the co-evolution of film and broadcast TV production, demonstrating how the characteristics of the creative industry and metropolitan changes are intertwined with each other in shaping the geographical pattern of the media cluster.

Purpose We aimed to assess local tumor progression (LTP) rate and associated prognostic factors in 92 patients who underwent radiofrequency ablation (RFA) using saline-perfused electrodes to treat hepatocellular carcinoma (HCC) (≤ 5 cm). Materials and Methods Total 92 patients with 148 HCCs were treated with RFA using saline-perfused electrodes, from 2009 to 2015. We retrospectively evaluated technical success, technique efficacy, and LTP rates. Potential prognostic factors for LTP were perivascular tumor, subphrenic tumor, artificial ascites, tumor size (≥ 2 cm), and previous treatment of transarterial chemoembolization. Analysis was performed by lesion, rather than by person. Results During follow-up period from 1 to 97.4 months, total cumulative LTP rates were 7.9%, 11.4%, and 14.6% at 1, 3, and 5 years, respectively. These values were significantly higher in the perivascular (35.1%; p = 0.009) and subphrenic group (38.9%; p = 0.002) at 5-year. We did not observe any significant difference in LTP according to other prognostic factors (p > 0.05). Conclusion RFA with saline-perfused electrode is a safe and effective treatment modality for HCC (≤ 5 cm), with lower LTP rates. Nevertheless, perivascular and subphrenic HCCs demonstrated higher LTP rate than other sites. It is imperative to note that perivascular and subphrenic location of HCC are associated with a high risk of local recurrence, despite the use of saline-perfused electrodes.

날씨가 더워지고 있다. 혹서가 계속되면 육계에서 3주령정도까지는 별다른 문제가 없으나 이후부터는 견디지를 못하고 폐사가 계속 나오게된다. 열사병인 것이다. 사료는 다 먹고 폐사가 나오니 이를 어쩌면 좋은가? 열사병을 막기 위해서는 근본적으로 계사의 방서대책을 세워야 하는 것이건만 사정은 여의치 않고$\cdots$ 여름철 농장에서 심심찮게 보는 일이다. `80년대 중반부터 보고된 내용중 손쉽게 대처할 수 있는 응급조치 하나를 소개한다.

2000년도를 기점으로 바이오 붐을 타고 많은 신약 및 바이오 관련 기업들이 설립되었고 이에 4년여의 시간이 경과되었다. 초기 바이오벤처는 국책과제, 투자유치 등을 통해 기반 연구를 수행하였으나, 현재는 기업 생존을 위해 지금까지 수행된 연구결과를 사업화하고 수익을 창출하기 위한 다각적인 노력을 기울이고 있는 시점이다. 많은 바이오 벤처들은 궁극적으로 맞춤의약시대에 걸맞은 신약개발, 장기이식, 유전자치료 등의 목표를 설정해 두고 있다. 그러나 이러한 목
