난치성 궤양 형태로 발현한 십이지장의 MALT 림프종 1예
송민근,강현우,김재학,이준규,임윤정,고문수,이진호,김어진 대한소화기내시경학회 2011 Clinical Endoscopy Vol.43 No.1
Mucosa-associated-lymphoid-tissue (MALT) lymphomas are the most common primary gastrointestinal lymphomas. The stomach is the most common site of involvement in the GI tract. However, MALT lymphoma of the duodenum is rare. The differential diagnosis in a refractory peptic ulcer are current smoking, NSAID use, hypersecretory conditions (gastrinoma and Zollinger-Ellison syndrome), neoplasms, infection (cytomegalovirus, syphilis, and tuberculosis), and Crohn’s disease. Endoscopic findings of duodenal MALT lymphoma are classified as ulcerative, polypoid, and diffuse types. The ulcerative type is the most common type of duodenal MALT lymphoma. Here, we report a case of a 64-year-old male with a history of a refractory duodenal ulcer who was diagnosed with a duodenal MALT lymphoma by immunohistochemical staining. MALT (mucosa-associated lymphoid tissue) 림프종은 위장관 림프종에서 가장 호발 하는 림프종으로 십이지장에서는 그 빈도가 매우 낮다. 십이지장 MALT 림프종의 내시경적 소견으로는 궤양형, 융기형, 미만형으로 분류 되는데 그 중 궤양형이 가장 흔한 소견이다. 난치성 궤양의 경우 흡연, 비스테로이드성 진통제 사용, 산의 과다 분비 상태(gastrinoma, Zollinger- Ellison syndrome 등), 종양, 크론병, 감염(결핵, 매독, cytomegalovirus) 등을 고려해야 한다. 64세 남자 환자에서 난치성 궤양 형태로 발현된 십이지장 MALT 림프종 1예를 경험하였기에 문헌 고찰과 함께 이를 보고한다.
태국의 일대일로 철도개발 특징과 범아시아철도(泛亞鐵道)에의 시사점
송민근 한국해운물류학회 2022 해운물류연구 Vol.38 No.2
This study analyzes the major issues and problems that Thailand's BRI Railway project has been delayed for a long time at the time when the China-Laos section is completed and the project of Thailand, the next section, is in visualized. The research presented some problems identified in the process by dividing them into basic environment, application of standards, business conditions, cost benefits, etc. The fact that Thailand has reduced the scope of its business and applied China's railway standards has raised the possibility that Chinese standards for high-speed rail would be applied to Pan-Asian railway in the future, which can be viewed as an advantage from the point of view of China. However, the difficulty in negotiating business terms and the fact that China's role eventually decreased can be regarded as a huge loss from China's point of view. Thailand has reduced its dependence on China in terms of procurement of project costs, but the cost-benefit problem has not yet been resolved. In order for Thailand to solve the cost-benefit problem, there is still a high possibility that Thailand's dependence on China will increase. The problems that emerged in Thailand's railway development process will provide implications not only for countries located in the path of Pan-Asian railway, but also for many countries participating in BRI project. 본 연구는 일대일로 범아시아철도의 중국-라오스 구간이 완공되고, 다음 구간인 태국의 철도 연결사업이 본격화되는 시점에서 사업 배경이 되는 국가별 무역 관계를 검토하고 사업 과정의 주요 이슈와 문제점을 기초환경, 표준 적용, 사업 조건, 비용 편익 등으로 구분하여 제시했다. 태국 철도에 중국 철도 표준이 적용된 점은 향후 범아시아철도에 중국식 고속철도 표준궤가 적용될 가능성을 높이게 되었고 이는 일대일로를 추진하는 중국 관점에서 큰 이익으로 볼 수 있지만, 사업 과정에서 중국의 비중과 역할이 축소된 점은 중국의 손실로 간주될 수 있다. 태국은 사업비 조달에서 많은 일대일로 참여국이 우려하는 중국 의존도를 크게 낮추었지만, 태국이 철도 물동량을 높이기 위해 중국과 협력 구조가 필요하고 중국 의존도가 높아질 가능성은 여전히 크다. 태국의 철도개발에서 나타난 문제점과 특징은 범아시아철도 경로에 해당되는 국가와 많은 일대일로 사업 참여국에게 시사점을 제공할 수 있을 것이다.
수소 연료 생산의 효율향상을 위한 초음파 응용에 관한 연구 - 압력센서 계기에 의한 -

The production of hydrogen fuel depends basically on the water electrolysis. The ultrasonic effects the decrease of the overpotential in a water electrolysis. A study on the overpotential which activates the hydrogen production is the core to elevate the hydrogen production efficiency on the principle. A pressure sensor system by a new idea is developed and applied. Solutions are 4 kinds of KOH concentration such as 0%, 10%, 20%, and 30%. Two frequency bands of the ultrasonic transducer are 28kHz and 2MHz. The directions of ultrasonic forcing are the vertical direction and the horizontal direction. The temperatures are two states, i.e., no constant and constant. Experiments are carried out sequentially in order in three cases of no ultrasonic forcing, ultrasonic forcing, and ultrasonic discontinution. In results, it is clarified that the ultrasonic effects the decrease of overpotential to elevate the efficiency of hydrogen production.
Arthroscopy for Treating Osteochondroma of Distal Radius in 68 Thoroughbred Horses
송민근,Masaaki Tagami,Fumiki kato,Tsukasa Suzuki,Takashi Yamaga,강태영,서종필 한국임상수의학회 2018 한국임상수의학회지 Vol.35 No.3
Osteochondroma (OC) is a cartilage-capped exostosis. In horses, OC commonly develops on the caudaldistal metaphysis of the radius (CDMR). The purpose of study was to describe the outcomes of arthroscopy for thetreatment of OC on CDMR. Diagnosis was based on clinical signs (lameness and distention of carpal sheath),radiography (location and size of OC), and ultrasonography (location of OC, torn deep digital flexor tendon, fibrin,and effusion of carpal sheath). Arthroscopy was performed on 68 Thoroughbred horses with OC on CDMR. Sixtyof the 68 cases showed deep digital flexor tendinitis as a result of sharp protuberances of the OC. All horses survived,and 62 of the 68 cases returned to athletic function (racing) after arthroscopy. The present study demonstrated thatarthroscopy is useful for treating OC of CDMR in horses.
Analysis of the Air Transport Network Characteristics of Major Airports
송민근,여기태 한국해운물류학회 2017 The Asian journal of shipping and Logistics Vol.33 No.3
The world’s major airports are directly connected to hundreds of airports without intermediate routes. This connectivity can be described as the network in which the airport becomes a node and the route becomes a connection line. In this regard, this study analyzes the air transport network of 1,060 airports using the social network analysis (SNA) methodology. We consolidated the data from three airline alliances and established a network of 1,060 airports and 5,580 routes in 173 countries. Many previous studies on air transport network examined several specific airports or regions and mainly utilized the internal indicators of airports. Conversely, this study conducted a comprehensive analysis covering 173 countries by using air route, which is an external indicator of airports. This study presented the general characteristics of major countries and regions from the perspective of SNA and compared the individual networks of the United States and China, which have the greatest influence on international air logistics within the scope of the entire network analysis. This study can aid in the understanding of air transport networks and logistics connectivity in inter-city and inter-country transport.
