Purpose: Merkel cell carcinoma, also called neuroendocrine carcinoma, is a very rare type of skin cancer that develops as Merkel cells grow out of control. Merkel cell carcinoma is reported below 1% of whole skin neoplasms in the United States and is known that the 2-year survival rate is about 50~70%. The principles of treatment are wide excision of primary lesion with radiotherapy and/or chemotherapy that decrease the local recurrent rate. There has been no report of reconstruction with free flap after resection of Merkel cell carcinoma in Korea. Methods: We reconstructed the skin and soft tissue defect after wide excision of Merkel cell carcinoma with anterolateral thigh perforator free flap in two cases. No distant metastasis was found at the preoperative imaging work-up. In one case, preoperative chemotherapy was performed and the size of lesion was decreased. Results: There were no recurrence and significant complications. Functionally and aesthetically satisfactory results were obtained with reconstruction. Conclusion: Wide excision and reconstruction with anterolateral thigh perforator free flap for Merkel cell carcinoma patient is the first report in Korea. We regard this method as the treatment of choice in Merkel cell carcinoma.

Purpose: For reconstruction of lower extremity defects, various flaps can be used and the appropriate flap must be selected and applied according to the size of the defect. In particular, in cases where the defect size is small to moderate, thinner or smaller volume flaps are useful. The authors performed reconstruction of small to moderate defects on the lower extremities using superficial circumflex iliac artery perforator free flaps and are reporting the results. Materials and Methods: Fifteen patients underwent reconstruction of defects on lower extremity areas using superficial circumflex iliac artery perforator free flaps from July 2011 to July 2012 at this hospital. The flaps were elevated from above the deep fat layer, and, in all cases, the vessel diameter of the flaps was less than 1mm, with the exception of superficial vein that accompanied it. Results: The mean follow up period was 4.46 months, and, despite a partial loss in the flap in two cases, there were no total losses. All donor sites were closed with primary closure, and there was no occurrence of complications, such as hematomas, seromas, or lymphorrheas. The patients were highly satisfied with the donor site scar since it could be masked by underwear. Conclusion: Compared to other flaps, superficial circumflex iliac artery perforator free flaps are thinner in thickness and smaller in volume, which results in a more natural contour of the recipient site after the operation. In addition, since the flap can be elevated from supra-deep fat layer, the operation time can be shortened, and lymphorrhea can be prevented, which in turn lessens donor-site morbidity.

김규남,Kim, Kyunam 기술경영경제학회 2020 Journal of Technology Innovation Vol.28 No.4

본 연구는 4차 산업혁명의 핵심 산업으로 주목받고 있는 스마트홈 관련 산업의 국민경제적 파급효과를 정량적으로 분석하여 그 잠재성을 평가하였다. 이를 위해 선행연구들에 대한 문헌검토(literature review)를 통해 스마트홈 관련 산업을 제조업과 서비스업으로 분류하고 외생화하였다. 그리고 2018년 산업연관표를 이용하여 이들 산업이 유발하는 생산, 부가가치, 고용 및 취업효과와 산업간 연쇄효과를 분석하였다. 분석결과 스마트홈 제조업과 서비스업은 각 산업 영역에서 타 산업에 비해 높은 수준의 부가가치유발효과를 보였으며 스마트홈 산업 내부적으로는 제조업의 서비스업 생산 견인 기능이 상대적으로 더 크게 나타났다. 또한 4차 산업혁명기술을 활용하는 산업답게 기술집약적인 산업과의 연관성이 높을 뿐만 아니라 스마트시티, 스마트카, 핀테크 등을 구현하기 위한 서비스 부문과도 깊이 연관되어 있음을 확인하였다. 한편 스마트홈 제조업은 후방파급효과가 전방파급효과에 비해 상대적으로 높은 최종 수요적 산업인 반면 스마트홈 서비스업은 전방파급효과가 후방파급효과에 비해 상대적으로 높게 나타나 중간재 산업으로서 타 산업으로의 공급 기능이 높은 산업임을 알 수 있었다. This study evaluated its potentials by quantitatively analyzing the national economic impact of the smart home-related industry, which is attracting attention as a core industry of the 4th industrial revolution. For the analysis, the smart home-related industries were classified into manufacturing and service industries through a literature review of the previous studies. Using the 2018 input-output table, this paper analyzed linkage effects between industries as well as spillover effects in the production, value-added, employment and job. As a result, the smart home manufacturing and service sectors showed a higher spillover effect in value-added than other industries in each industrial field. In the smart home industry, the spillover effects of manufacturing sector to service sector are larger than those of service sector to manufacturing sector. Moreover, it was confirmed that smart home industry was highly related to not only the technology-intensive industry, but also the service sector for smart cities, smart cars, Fin-tech, and etc. On the other hand, the smart home manufacturing sector is a final demanding industry with relatively higher backward linkage effect than forward linkage effect. In the smart home service sector, the forward linkage effect was relatively high compared with the backward linkage effect, indicating that it was an industry with a high supply function to other industries.

Purpose: As patients who take immediate breast reconstructions with TRAM flap have increased, concomitant or delayed other elective intra-abdominal operations in these patients also have increased. There are few reports of concomitant or delayed intra-abdominal operation in TRAM flap patients. We report our experiences and outcomes of these operations which is safe and feasible. Methods: We reviewed the charts and postoperative follow-up results of 11 patients among 471 consecutive patients who took immediate breast reconstruction with TRAM flap from December of 2002 to September of 2006. Four patients took concomitant intra-abdominal operation and 7 patients took delayed intra-abdominal operation between 1 to 52 months after TRAM flap Results: There were no significant postoperative abdominal and systemic complications. One patient who took concomitant intra-abdominal operation presented partial skin necrosis of abdomen, but recovered completely with conservative treatments. Two patients took transfusion in peri-operative periods. Conclusion: Concomitant or delayed intra-abdominal operation in immediate breast reconstruction with TRAM flap could be performed safely and feasibly when it is necessary. Furthermore, it could be helpful to patients and surgeons.

전투사례로 본 군사보안의 중요성 연구 - 6.25 전쟁 초기, 개성일대 전투를 중심으로-

김규남,이현희,Kim, Gyu-Nam,Lee, Hyun-Hee 한국융합보안학회 2016 융합보안 논문지 Vol.16 No.6

"역사는 거울"이라는 말은 반복되는 역사적 사실을 통해 우리는 적을 대비해야 한다는 뜻이다. 현재 우리는 북한의 핵과 미사일을 포함하는 각종 도발에 직면해 있다. 우리가 북한을 주적으로 설정하고 국민의 생명과 재산을 보전하기 위해서는 우리 군은 적의 위협에 항상 철저히 준비되어야 한다. 6.25 전쟁 전투사례를 보면 준비된 적과 무방비 상태의 국군 간에 벌어진 전쟁으로 요약할 수 있다. 북한군은 해방 이후 치밀한 계획 하에 중공군을 편입시키고 소련군 군사고문단 지원 하에 전투 장비를 배치하여 군단 급 훈련까지 마친 상태에 비해, 당시 국군은 대대급 훈련도 마무리 못한 상태였다. 전 평시 군사보안을 위해 나의 정보는 숨기고 적은 찾아서 대비해야 한다. 북한군은 전쟁을 준비하면서 치밀하게 국군의 편성과 배치, 그리고 운용사항에 대한 정보를 수집했으나 국군은 이에 대비하지 못해 초전에 고전을 면치 못했다. 이에 본고에서는 6.25 전쟁 초기, 개성일대 전투사례를 중심으로 군사보안의 교훈과 그 중요성을 제시하고자 한다. "History is a mirror" means that we should be prepared for the threats of enemies through learning from repeating history. Currently South Korea is facing various provocations, including North Korea's nuclear weapons and missile s. For the protection of the life and property of its people, South Korea should regard North Korea as a main enemy and be fully prepared for the threats. The Korean War was a war between well-prepared North Korea and ill-prepa red South Korea. After Liberation, North Korean army incorporated the Chinese Communist army, placed battle equi pment with the support of the Soviet army, and finished corps-level training while South Korea at that time did not finish battalion-level training. In wartime and peacetime, an army should improve military security by concealing its own information and find its enemy's information. North Korea carefully prepared for the war, collecting information about the organization, deployment and operation of the South Korean army. South Korean army failed to cope with it and had hard times in its early battles. In this paper, I will emphasize the importance of military security, focusing on the Battle of Gaeseong, the early part of the Korean War.

In this study, a numerical methodology is proposed for evaluating valve flow noise in a pipe conveying high pressure gas, and the effects of perforated plates on reduction of such valve flow noise are quantitatively analyzed. First, high-accurate unsteady compressible Large Eddy Simulation techniques are utilized to predict flow and flow noise by a valve in a high-pressure pipe. The validity of the numerical result is confirmed by comparing the predicted wall pressure spectrum with the measured one. Next, the acoustic power of downstream-propagating acoustic waves due to the valve flow is analyzed using an acoustic power formula for acoustic waves propagating on mean flow in a pipe. Based on the analysis results, perforated plates are designed and installed downstream of the valve to suppress the valve flow noise and the acoustic power of downstream-going acoustic waves is predicted by using the same numerical procedure. The reduction by 9.5 dB is confirmed by comparing the predicted result with that of the existing system. Based on these results, the current numerical methodology is expected to be used to reduce valve flow noise in an existing system as well as in a design stage.

북한의 핵 및 미사일 개발과 우리의 대응방안

이현희,김규남,Lee, Hyun Hee,Kim, Gyu Nam 한국융합보안학회 2017 융합보안 논문지 Vol.17 No.2

현재 북한에서 3대 세습체제의 김정은은 역대 김일성과 김정일 정권보다 더욱 호전적으로 핵 및 미사일 도발을 자행하고 있다. 대한민국의 역대 정부는 나름대로의 북한의 도발을 억제하는 노력과 한반도에서의 평화정착을 위한 방안을 제시하여 왔지만 결과론적으로는 통치자로서의 기본 역할에 국한되어 온 것이 사실이다. 2017년 2월 미국의 트럼프 행정부 출범에 따라 미국 대선 과정에서의 공약과 현재에는 대통령령으로서의 통치 스타일을 고려할 때 한반도 문제와 관련하여 다소 희망적이었던 것은 사실이나, 최근 들어 트럼프 대통령의 한반도 관련 다양한 발언은 우리의 상황을 암울하게 하고 있다. 이의 연장에서 김정은의 핵 및 미사일 집착은 역대 북한 정권이 기초를 닦아놓았고 이제 마무리하여 실전배치를 앞둔 상황에서 핵 및 미사일의 경량화, 고도화, 다종화를 기치로 더욱 무모한 도발을 하고 있는 현실이다. 이에 우리는 현재 안보상황을 과거처럼 타국에만 의존할 수 없으며, 대한민국 스스로 무엇을 어떻게 할 것인가를 찾기 위해 북한의 핵 및 미사일 도발을 중심으로 대응방안을 제시하고자 한다. Today, Kim Jong-un, the third-hereditary regime in North Korea, is committing Nuclear Provocation more aggressively than the past when Kim Il-sung and Kim Jong-il dominated. Past South Korea government had suggested plans to restrain the provocation from North Korea and bring stabilization in the Korean Peninsula. However, consequentially it was limited to the primary role of the President. When President Trump takes over the government in February 2017, it has attracted the expectation about the issues occurred on the Korean Peninsula due to the pledge that he promised during the presidential election and his govern style. However, various speeches about the Korean Peninsula that he spoke recently made situations depressed about what South Korean currently encounters. Furthermore, previous regime in North Korea has laid the foundation for Kim Jong-un to be obsessed more on the nuclear and missile which has led him to provoke more imprudently by highlighting the light weight, advanced, and various kinds of nuclear and missiles. Thus, we would like to propose counter measures in order for South Korean government to handle and solve the issues that they encounters by themselves based on North Korea's Nuclear Provocation instead of relying on other countries to get involved and help.
