Competitiveness of the country’s farming and fishing villages is gradually dropping in step with industrial opening in the wake of FTA, decrease of rural population due to rapid urbanization, aging of rural population. On the other hand, farming and fishing villages are getting their importance more than ever because of social and economical changes such as drive of low carbon green growth, space for leisure and holidays, lifestyle focusing on wellbeing. These days, a diverse range of government-level urban-rural exchange projects are under way in an effort to boost competitiveness of farming and fishing villages, and initial survey on those villages was conducted by regional survey of “Agriculture, Forestry & Fishery Census” in 2010. And this study aims to suggest future policies through analysis of nationwide characteristics of urban-rural exchange. The study found urban-rural exchange had been carried out in 20.1% of all administrative divisions across the country. Its large spatial distribution comprised Gangwon-do for exchange of education and culture, Chungcheong-do for exchange of products, Gyeonggi-do and Gangwon-do for exchange for purpose of recreation and holidays. In addition to such finding, clustering areas were shown different by exchange type of humans, products, education and culture, recreation and holidays. And specialized support policies by area need to be considered.

운용유지단계에서 ANP를 이용한 무기체계 소프트웨어 품질 평가 방법 연구

김홍주,박찬현,김의환 한국방위산업학회 2018 韓國防衛産業學會誌 Vol.25 No.2

In this study the weapons system software quality assessment model is developed using the network analysis method in the operation/Support phase. Of the quality characteristics of ISO/IEC 25010, 6 main features and 18 subtaries were derived in accordance with the view of quality improvement. Based on ISO/IEC 25023, the metrics for the quality assessment were established and the importance among the quality characteristics was calculated through network analysis. The quality evaluation model developed was verified by applying it to the real case. To conclude, the quality level indicating the results and importance of each quality characteristic was derived along with quantitative scores, and based on these findings improvement priority and counter measures were also presented. 본 연구에서는 운용유지단계에서 네트워크 분석법을 이용하여 무기체계 소프트웨어 품질 평가 모델을 개발한다. ISO/IEC 25010의 품질 특성 중 품질 개선의 관점에 부합한 6개의 주특성과 18개의 부특성을 도출했다. 그리고 ISO/IEC 25023을 바탕으로 품질 평가에 대한 측정 기준을 수립했으며 네트워크 분석법을 통해 품질 특성 간의 중요도를 산정했다. 개발한 품질 평가 모델은 실제 사례에 적용함으로써 검증했다. 그 결과 각 품질 특성의 평가 결과와 중요도를 반영한 품질 수준을 정량적인 점수로 도출했고 이를 통해 개선의 우선순위와 대응방안을 제시 할 수 있었다.

Clinical outcomes of biliary and duodenal self-expandable metal stent placements for palliative treatment in patients with periampullary cancer

김홍주 소화기인터벤션의학회 2017 Gastrointestinal Intervention Vol.6 No.3

Background: Endoscopic self-expandable metal stent (SEMS) insertions for palliation of malignant biliary and duodenal obstructions have been revealed to be an effective treatment. We present our clinical experience with the use of SEMS for malignant biliary and duodenal obstructions caused by periampullary cancer. Methods: We performed a retrospective review of all patients who underwent endoscopic biliary and duodenal SEMS insertion for palliation of malignant biliary and duodenal obstruction caused by periampullary cancer between July 2007 and October 2016. The patients received simultaneous or sequential endoscopic biliary stenting and duodenal stenting with COMVITM stents (partially covered; Taewoong, Seoul, Korea). Results: The final diagnoses of our enrolled patients were 15 pancreas head cancer, and 3 distal common bile duct (CBD) cancer. The main stricture site in the duodenum was bulb (n = 4, 22.2%), 2nd portion (n = 9, 50.0%), and 3rd portion (n = 5, 27.8%). The technical success rates of CBD and duodenal stenting were 100% (18/18), and 100% (18/18), respectively. The clinical success rates of CBD and duodenal stenting were 100% (18/18), and 88.9% (16/18), respectively. Median actuarial stent patency for biliary and duodenal SEMS were 6.5 months (range, 1–12 months) and 4.5 months (range, 1–14 months), respectively. Three patients (16.7%) had recurrent biliary obstruction and all of them underwent percutaneous trans-hepatic biliary drainage (PTBD) with biliary SEMS reinsertion. Three other patients (16.7%, totally different from patients with CBD restenosis) had recurrent duodenal obstruction and all of them underwent upper gastrointestinal endoscopy with duodenal SEMS reinsertion. Conclusion: Endoscopic SEMS insertions for simultaneous palliation of malignant biliary and duodenal obstruction in patients with periampullary cancer may provide a safe, and less invasive alternative to surgical palliation with a successful clinical outcome.

제어설비 계통에서의 노이즈장해 사례 및 대책별 효과 분석

김홍주,유상봉,이호성,Kim, Hong-Ju,Yoo, Sang-Bong,Lee, Ho-Sung 한국조명전기설비학회 2005 조명·전기설비학회논문지 Vol.19 No.6

최근 제어설비 계통은 전력변환장치와 센서등의 사용이 증가함에 따라 많은 노이즈가 발생되어 설비의 오동작이나 제어 회로의 메모리 손실과 같은 문제들이 야기되고 있다. 따라서, 본 논문에서는 다양한 제어설비 계통에서 발생되고 있는 노이즈의 특성을 계측하고 분석하였다. 또한 NCT, 등전위 접지, PNR, 노이즈필터 등을 사용한 노이즈저감 대책을 적용한 결과로 이들 대책들이 노이즈 문제 해결에 매우 효과적임을 확인하였다. Recently an increase of sensor and power trandusers in control equipment system has caused many kinds of noise the mis-operation equipment and demage program memories of control circuits. In this paper, the noise character of the various control equipment system has been measured and analyzed. Additionally, the countermeasure to reduce noise like as Noise Cut Transformer, Equipotential Bonding, Power Noise Rejector, Noise Filter has been applied and confirmed the effective results to solve the trouble of noise.

경피 경간 담관 배액관 유도하의 담관 내 삽관: 수정 랑데부 술기

김홍주,최선형,박정호,박동일,조용균,손정일,전우규,김병익 대한소화기내시경학회 2007 Clinical Endoscopy Vol.34 No.3

Background/Aims: To describe a simple and useful modification of the rendezvous technique using a PTBD tube as guidance. Methods: From January 2005 to August 2006, a total of 436 ERCPs were performed. A diagnosis of choledocholithiasis was made in 235 cases. Deep cannulation of the bile duct using standard techniques was unsuccessful in 27 patients (11.5%). A precut papillotomy led to successful cannulation in 16 out of these 27 patients (59.3%). The remaining 11 patients (40.7%) underwent PTBD with the tube tip placed in the second portion of the duodenum. Bile duct cannulation was attempted with the guidance of a PTBD tube in 9 cases. In the other 2 cases, the transduodenal approach was impossible due to a previous Billroth II operation. Results: Bile duct cannulation guided by a PTBD tube, which is also known as a modified rendezvous procedure, was successful in 9 out of 11 patients (81.8%). Deep cannulation of the bile duct was achieved in 100% of patients, who could be treated by endoscopy. There were 7 cases of transient hyperamylasemia (77.8%) but no procedure-related major complications or mortality. Conclusions: Bile duct cannulation guided by a PTBD tube in patients with choledocholithiasis can be recommended when ERCP is unsuccessful using the standard technique. (Korean J Gastrointest Endosc 2007;34:138-142) 목적: 기존의 랑데부 수기는 담관 선택 삽관을 위하여 내시경 및 경피 경간 담관 조영술을 병합하는 것이다. 본 연구에서는 기존의 랑데부 수기에서 이용하는 유도철사 대신에 경피 경간 담관 배액(PTBD)관의 유도하에 담관 선택 삽관을 시행하는 수정 랑데부 술기의 임상적 유용성에 대하여 알아보고자 하였다. 대상 및 방법: 2005년 1월부터 2006년 8월까지 강북삼성병원에서 내시경 역행성 췌담도 조영술(ERCP)을 시행한 436명의 환자 중 총수 담관 담석으로 최종 진단되었던 환자는 235명이었고, 이들 환자 중 표준 삽관법으로 담관 선택 삽관에 실패하였던 환자는 27명(11.5%)이었다. 이 환자들 중 16명(59.3%)은 예비절개술을 통하여 담관 선택 삽관에 성공하였으나 나머지 11명(40.7%)에서는 담관 삽관에 실패하여 PTBD를 시행하였고 PTBD 관의 첨단은 십이지장 제2부에 위치시켰다. 11명의 환자 중 2명의 환자는 이전의 위공장문합수술로 인하여 십이지장 제2부로의 내시경 접근이 불가능하였고, 나머지 9명의 환자에서 PTBD 관의 유도하에 담관 선택 삽관을 시도하게 되었다. 결과: PTBD 관의 유도하에서 담관 선택 삽관을 시행하는 수정 랑데부 술기는 9명의 환자에서 모두 성공하였다. 선택 삽관은 주로 PTBD관의 12시 혹은 9시 방향에서 이루어졌고 삽관 후에 유두 괄약근 절개술 및 총수 담관 담석 제거술 등의 치료 내시경 수기는 모든 환자에서 가능하였다. 일과성 고아밀라제혈증이 7명(77.8%)의 환자에서 관찰되었으나 시술과 관련된 주요 합병증 및 사망 예는 없었다. 결론: 담관 담석이 있는 환자에서 기존의 술기로 담관 선택 삽관에 실패하였던 환자에서는 PTBD관 유도하에서의 담관 선택 삽관 술기, 즉 수정 랑데부 술기의 시행이 고려될 수 있을 것으로 생각한다.
