본 연구에서는 정상상태의 비선형 열탄성 문제에 대하여 탄성 계수 및 열전도 계수에 대해서 보조변수법을 이용한 연속체 기반의 설계민감도 방정식을 유도하였고, 온도와 변위장이 연성된 보조방정식을 정의하여 효율적으로 설계민감도 해석을 수행하여 위상 최적설계에 적용하였다. 수치 예제를 통하여 열탄성 문제에서 위상 최적설계가 갖는 요소망 의존성을 살펴보았다. 또한 열 하중이 지배적인 경우와 기계적 하중이 지배적인 경우를 비교하여 다중 물리 연성문제에서 위상 최적설계가 갖는 하중에 대한 의존성을 고찰하였다. In this paper, we have derived a continuum-based adjoint design sensitivity of general performance functionals with respect to Young' modulus and heat conduction coefficient for steady-state nonlinear thermoelastic problems. An adjoint equation for temperature and displacement fields is defined for the efficient computation of the coupled field design sensitivity. Through numerical examples, we investigated the mesh dependency of the topology optimization method in the thermoelastic problems. Also, comparing the dominant loading cases of thermal and mechanical ones, the loading dependency of topology design optimization in coupled multi-physics problems is investigated.

남북한 교육통합의 과제 – 북한이탈주민 학력인정 제도의 현황과 개선 방안

문민영 법무부 2017 統一과 法律 Vol.- No.32

Currently, there are considerable differences in school systems between South and North Korea. Not only is the school system different, but also the subjects and course hours prescribed in the curriculum are different. For instance, North Korea has a liberal arts course on ‘political thoughts’ in the curriculum for teaching the revolutionary ideas of Kim Il Sung, Kim Jong Il and Kim Jong Un. The education level of students who have graduated from each school in South and North Korea vary due to the differences in compulsory education period, school age and teaching methods, etc. If and when the two Koreas are united, recognition of academic background made in the North Korea will become a controversial issue. In fact, recognition of academic background and qualifications from East Germany was one of the most pressing issues facing the German unification. Germany dealt with this issue at the level of the federal government through the ‘Joint Commission on Education’ and the ‘Unification Treaty’. We can prepare and get ready for recognition of academic background for North Korea starting from now. Currently, the academic background of residents escaping from North Korea at elementary and secondary school levels are recognized through deliberation by Academic Background Deliberative Committee at each metropolitan/provincial Office of Education. However, it has been pointed out that the criteria for and result of recognition of academic background vary by each metropolitan/provincial Office of Education. This is related to the fundamental issue of distribution of educational authority between the state and local governments. In seems desirable that the principal deliberation criteria for academic background recognition of residents escaping from North Korea shall be prescribed by the state, while the actual recognition of academic background for residents escaping from North Korea are determined by each metropolitan/provincial Office of Education within the purview of such deliberation criteria in accordance with the principle of justice and equity. 현재 남북한의 학교제도는 차이가 적지 않다. 학제(學制)가 서로 다를 뿐만 아니라, 교육과정(敎育課程)에서 정한 교과와 수업시수도 상이하다. 일례로 북한은 교육과정에 ‘정치사상교양’ 교과를 두어 김일성, 김정일, 김정은의 혁명사상을 가르치고 있다. 의무교육기간, 학령, 수업방식 등도 차이가 있기 때문에, 남한과 북한에서 각각 학교를 졸업한 학생들의 교육수준 또한 다를 수밖에 없다. 남북통일이 되면 북한에서의 학력(學歷)을 인정하는 문제가 현안으로 대두될 것이다. 실제로 독일 통일 과정에서도 구동독의 학력 및 자격인정 문제가 가장 시급한 쟁점이었다. 독일은 ‘동서독 공동교육위원회’ 및 ‘통일조약’을 통해 이 문제를 연방정부 차원에서 정리하였다. 우리는 북한에서의 학력인정 문제를 지금부터 준비하고 대비할 수 있다. 현재 북한이탈주민은 각 시․도교육청 학력심의위원회의 심의를 거쳐 초․중등학교 학력을 인정받고 있다. 다만 각 시․도교육청 별로 학력인정 기준 및 결과가 다르다는 점이 지적되었다. 이는 기본적으로 국가와 지방자치단체가 교육권한을 어떻게 분배할 것인지와 연관이 있다. 생각건대 북한이탈주민의 학력인정에 대하여는 국가가 주요 심의기준을 정하고, 각 시․도교육청이 위 심의기준의 범위 내에서 공평과 형평의 원칙에 따라 개별 북한이탈주민의 학력을 인정하는 것이 바람직할 것으로 보인다.

Effective treatment of eosinophilic granuloma in a cat using tacrolimus with prednisolone

문민영,서국현,권용진,김하정 충북대학교 동물의학연구소 2017 Journal of Biomedical and Translational Research Vol.18 No.3

A 2-year-old, spayed male Bengal cat was referred to our clinic due to a mass lesion on the upper lip, as well as lower lip swelling and redness. Furthermore, well-circumscribed, raised, pink lesions were found in the oral cavity. Complete blood counts (CBC) and serum biochemistry profiles revealed no remarkable findings. Bacterial and fungal cultures of the lesion in the oral cavity were negative. Fine needle aspiration of the lesions revealed numerous eosinophils. Based on both clinical examination and cytological evaluation, the cat was diagnosed with feline eosinophilic granuloma. As an initial treatment, oral prednisolone (PDS) with cyclosporine was administered. However, the cyclosporine caused the cat to vomit. The lesion was markedly improved after 2 weeks of PDS-only therapy; this was subsequently tapered for 2 months and discontinued. However, one month later, the lesion had relapsed. The cat was then treated for one month using tacrolimus with PDS, and the clinical signs of eosinophilic granuloma gradually improved. The tacrolimus was gradually tapered for 1 month, and the PDS was gradually tapered for 4 months. There is no standard protocol for the investigation and treatment of feline eosinophilic granuloma. The cat in this report was administered immunosuppressive therapies to treat eosinophilic granuloma. This case report provides evidence the combination of PDS and tacrolimus is effective for reducing relapse in feline eosinophilic granuloma.

Real-world Safety and Effectiveness of Indacaterol/Glycopyrronium in Chronic Obstructive Pulmonary Disease Patients in South Korea

이재천,문민영,이혜미 대한결핵 및 호흡기학회 2018 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.126 No.-

Background: Inhaled indacaterol/glycopyrronium (IND/GLY), a combination of long-acting β-agonist and long-acting muscarinic antagonist was approved in over 90 countries, including Korea, for maintenance therapy of chronic obstructive pulmonary disease (COPD). This is an interim analysis of a post-marketing surveillance study in Korea to evaluate the real-world safety and effectiveness of IND/GLY. Methods: This is an open-label, observational, prospective study in which COPD patients, who were newly prescribed with IND/GLY (110/50 μg once daily), were evaluated for 12 or 24 weeks. Safety was assessed based on the incidence of adverse events (AEs), serious adverse events (SAEs), and AEs of special interest including cardiovascular (CV) disorders. Effectiveness was analyzed based on the physician’s clinical assessment, considering changes in symptoms and lung function. Results: Of the 334 enrolled patients receiving IND/GLY, 329 patients and 302 patients were included for the safety and effectiveness analysis, respectively. AEs were reported in 101 patients (30.70%), while SAEs in 33 patients (10.03%). Regarding AEs of special interest, among 6 patients (1.82%) with CV disorders, only 1 case with palpitations noted to be associated with the study drug. The effectiveness rate was 93.71%, including patients reporting as ‘improved’ (69.54%) and ‘maintained’ (24.17%). Conclusion: In real-world clinical setting, IND/GLY is well-tolerated in COPD patients with no significant safety issue.

Improvement of Megaesophagus after Treatment of Concurrent Hypothyroidism

고경빈,김준영,최형일,문민영,서국현,김하정 한국임상수의학회 2018 한국임상수의학회지 Vol.35 No.1

A 7-year-old female American cocker spaniel presented with chronic regurgitation and megaesophagus onradiography at a local hospital. Dry and coarse hair coat, tail alopecia, and bradycardia were observed during physicalexamination. Mild, non-regenerative anemia was indicated by complete blood count (CBC) analysis. Concurrenthypercholesterolemia and hypertriglycemia were indicated by biochemistry tests. Decreased levels of total and freethyroxine (T4) and increased canine thyroid stimulating hormone (cTSH) levels were also detected. Megaesophaguswas confirmed by radiographic examination. Based on the results, a diagnosis of hypothyroidism with megaesophaguswas made. The patient was initially treated with levothyroxine sodium at a dosage of 0.02 mg/kg twice a day. Aftertwo weeks of treatment for hypothyroidism, the dilated esophagus returned to its original size and no further regurgitationwas observed. No relapse was observed during two months of follow-up.
