The brachial plexus originates from the ventral rami of spinal nerves C5–T1 and lies between the anterior and middle scalene muscles. Brachial plexus injury can occur as a rare complication of neck dissection or in association with trauma, malignancy, or radiotherapy. We performed modified radical neck dissection in a female with cervical lymph node metastasis of a recurrent papillary thyroid carcinoma. Brachial plexus injury occurred because of severe adhesion and anatomical distortion during the surgical revision and was immediately treated via end-to-end neurorrhaphy. After surgery, the patient felt pain and numbness in her right shoulder and arm. Motor function was grade 0 on right shoulder flexion, arm abduction and elbow flexion. After 1 year of follow-up, both motor and sensory function had fully recovered. This is the first reported case of complete motor function restoration after brachial plexus neurorrhaphy in a patient treated in the Republic of Korea.

ASYMPTOTIC STABILITY OF NON-AUTONOMOUS UPPER TRIANGULAR SYSTEMS AND A GENERALIZATION OF LEVINSON'S THEOREM

이민기 충청수학회 2020 충청수학회지 Vol.33 No.2

This article studies asymptotic stability of non-auto nomous linear systems with time-dependent coefficient matrices $\{A(t)\}_{t\in \mathbb{R}}$. The classical theorem of Levinson has been widely used to science and engineering non-autonomous systems, but systems with defective eigenvalues could not be covered because such a family does not allow continuous diagonalization. We study systems where the family allows to have upper triangulation and to have defective eigenvalues. In addition to the wider applicability, working with upper triangular matrices in place of Jordan form matrices offers more flexibility. We interpret our and earlier works including Levinson's theorem from the perspective of invariant manifold theory.

가공작업에 적합한 강성이 큰 로봇트 암 설계

이민기 國立 昌原大學校 産業技術硏究所 1993 産技硏論文集 Vol.7 No.-

This paper presents the design of a high stiff robot arm. The robot is specially designed for removing riser and the bur of casting. In the casting process, the riser and the bur generated around the casing They must be removed by grinding, cutting, and milling. These machining works are defined as the fettling which creates an unpleasant environment due to lots of noise and dust. Therefore, the fettling needs the robot which automatically d you the machining works. The robot must have the special specification, which is a high stiffiness. This specification can not be satisfied by a common industrial robot. The arm structure causes a large deflection a high stiff robot arm. Several links support a robot gripper so strongly that it increase the stiffiness.

F-19 Effectiveness of the combination of rifampin, fluoroquinolone, and ethambutol in the treatment of pulmonary tuberculosis

이민기,조경욱,심태선 대한결핵 및 호흡기학회 2016 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.121 No.-

Background: Among the first-line anti-tuberculous (TB) drugs of isoniazid (INH), rifampin (RIF), and pyrazinamide (PZA), RIF is the least likely hepatotoxic. In addition, inclusion of RIF in the regimen can reduce the treatment duration dramatically. Fluoroquinolone (FQ) has a good anti-TB effect and is least likely hepatotoxic. Accordingly, the combination of RFP, FQ, and ethambutol (EMB) may be a good option for the treatment of TB, especially in patients with underlying liver disease (ULD) or drug-induced liver injury (DILI). Methods: Culture-positive pulmonary TB patients who had been treated with the combination of RIF, FQ, and EMB (or cyclo-serine) for more than 50% of treatment duration were enrolled retrospectively and clinical characteristics and treatment outcomes were analysed. Results: The mean age of 94 patients was 56.1 (±16.5) years and male was predominant (58/94). DILI was the main cause of the use of this regimen in 44 patients (46.8 %). Twenty patients (21.3%) had ULD. INH-resistant TB was 44.7% (42/94). In 8 patients (8.5%), other adverse events except DILI induced changing to this regimen. The mean treatment duration was 296 (±72) days. Treatment success was achieved in 91.5% (86/94). Default, transfer-out, and death rates were 6.4% (6/94), 1.1% (1/94), and 1.1% (1/94), respectively. No relapse developed with a median follow-up of 421 days after treatment completion. Conclusion: A RIF, FQ, and EMB combination regimen could be a good option for the treatment of TB, especially in patients with ULD or DILI. Further prospective studies are needed.

The Yeondeunghoe's Sohoeil was a royal rite during the Goryeo Dynasty in Korea that included various events such as the Jwajeonsuha (The King of Goryeo is congratulated while sitting in Ganganjeon), Nanga Chulgung(The king of Goryeo departs for the political affairs building riding in a carriage), the Aljojinui(The ritual of the Goryeo king performing a sacrificial rite at the building enshrining the portrait of King Taejo, the founder of Goryeo), and Nanga Hwangung(The king of Goryeo returned to the palace). The Jwajeonsuha and Aljojinui events were both spatially divided and focused on celebrating the king's majesty in different ways. The Jwajeonsuha centered around the Baekuijapgi(royal circus) and Tangakjeongjae(Royal music and theater) while the Aljojinui had a spatial division that separated the inside from the outside and allowed the king to know the Taejo alongside the officials. Both events highlighted the king's majesty and completed the meaning of the entire day of the annual meeting. The convention day followed the next day. The Jwajeonsuha was a ritual in Goryeo where the King wore different robes and attended different ceremonies as the "current king" and "descendant king". Officials attended the Jwajeonsuha and all officials below the prince attended the Aljojinui. The utilization of items and music emphasized the King's attendance and complex position. The Yeondeungnobu and Beopganobu expressed the positions of the "current king" and the "descendant king". In Confucian state rituals, the person performing the ritual is emphasized more than the object, but in the annual meeting, both the ancestors and current king were emphasized to make the current king's authority visible as a descendant king and a king. This passage discusses the complex meanings of the Yeondeunghoe's Sohoeil rite, which involve various aspects such as the division of space and the utilization of objects, from the perspective of the participants. The author argues that previous studies have overlooked the importance of examining the state rituals of Goryeo in detail, particularly from the perspective of the two dimensions that the King of Goryeo sought to express through the practice of the yeondeunghoe. The analysis in this paper is considered a working framework for understanding the Yeondeunghoe and should be supplemented by future ritual studies. 연등회 소회일은 좌전수하에서 시작하여 난가출궁, 알조진의, 난가환궁으로 진행되었다. 국왕은 강안전에서 백희잡기와 당악정재를 관람하였고, 연등위장과 연등노부를 동원하여 봉은사로 이동했다. 연등회는 ‘전각-마당-전각 문’의 구조를 기반으로 좌전행사와 알조진의가 설행되었다. 알조진의에서는 국왕만 출입 가능한 호내와 추밀만이 출입 가능한 호외가 구분되었고, 전정은 참여자들이 대기를 하는 장소였다. 이는 국왕과 관료들의 관계를 분리하면서 국왕의 위엄을 부각시키고 의례의 맥락이 ‘자연스럽게’ 전환되어 소회일 전체의 의미를 완성시켰다. 고려 국왕의 의례 참여 방식은 관복과 자리 배치로 나타났다. 국왕은 각 행사에서 입는 복장과 자리 배치를 다르게 하였는데, 이는 국왕으로서 참여하는 입장에 따른 변화를 나타낸다. 이를 통해 국왕의 권위를 가시화하고 후손 국왕으로서의 입장을 모두 갖추는 결과를 이끌어냈다. 등・준뢰와 부의・초요련과 평련 등의 의물을 사용하여 국왕의 통치행위를 강조하고 참석을 돋보이게 했으며, 음악연주와 탈 것을 사용하여 ‘현재 국왕’과 ‘후손 국왕’으로서의 복합적인 입장을 나타냈다. 이는 연등회가 ‘현재 국왕’의 권위와 ‘후손 국왕’으로서의 겸양을 모두 나타내는 행사임을 알 수 있다. 연등일 소회일의 의례들은 공간구분과 참여자의 입장에서 활용물품의 특징과 변화양상에 이르기까지 복잡한 의미들이 확인된다. 지난 연구는 연등회가 고려국왕의 권력을 수반하는 역할을 했다거나, 또는 중앙에서 치러진 불교식 행사로만 이해되었으며, 그 행사의 중요도 역시 ‘소회일’과 ‘대회일’의 명칭에 기인하여 이해되었다. 반면 연등회 소회일 절차에서 추출한 특징에 관한 본 논문의 검토는 고려 국왕이 연등회를 실시하면서 표현하고자 한 두 차원(현재 국왕과 후손국왕)의 입장에 기반하여 고려의 국가의례를 절차별로 세세하게 살펴봐야 할 필요성을 시사한다. 본 논문에서 분석한 내용들이 연등회 대회일을 포함한 전체적인 내용을 반영하지는 못했으므로 연등회를 이해하기 위한 하나의 작업가설적 분석 틀로 간주돼야 하지만, 기존 국가의례 연구에서 부각되지 못했던 지점들을 향후 의례연구를 통해 보완해 나가야 할 것이다.
