강재구,이지연,유연우 한국융합학회 2017 한국융합학회논문지 Vol.8 No.4

본 연구는 최근 전자 금융거래의 증가와 동시에 금융거래 정보의 탈취 혹은 변조 등 보안위협 또한 급증 하면서 안전한 보안 방안과 대응이 시급한 실정이다. 이에 종래에 사용된 사기방지시스템 혹은 이상금융거래 탐지 시스템(FDS, Fraud Detection System, 이하 FDS)을 최근 주목 받고 있는 빅데이터 관련 기술(이상금융거래에 대한 다양한 형태의 정형/비정형 금융거래 이벤트 데이터를 실시간으로 수집/저장하고 과학적 연관 분석 기법을 활용하여 비정상 행위를 탐지 및 차단할 수 있는 기능)을 활용하여 국내 금융회사인 A사에 개선 모델을 구축 하였 다. 구축결과 시나리오 고도화 분석을 통한 오검출을 최소화 하여 기존 시나리오 Detect탐지 대상의 감소 효과를 나타냈다. 아울러 FDS고도화에 대한 향후 발전방향을 제안하고자 한다. The growing number of electronic financial transactions (e-banking) has entailed the rapid increase in security threats such as extortion and falsification of financial transaction data. Against such background, rigid security and countermeasures to hedge against such problems have risen as urgent tasks. Thus, this study aims to implement an improved case model by applying the Fraud Detection System (hereinafter, FDS) in a financial corporation ‘A’ using big data technique (e.g. the function to collect/store various types of typical/atypical financial transaction event data in real time regarding the external intrusion, outflow of internal data, and fraud financial transactions). As a result, There was reduction effect in terms of previous scenario detection target by minimizing false alarm via advanced scenario analysis. And further suggest the future direction of the enhanced FDS.

高麗 元宗代 麗‧蒙 關係의 추이와 東寧府의 설치 목적

강재구 한국중세사학회 2016 한국중세사연구 Vol.0 No.47

Goryeo and the Mongol began to try figure out a way to establish a new relationship after entering into a peace pact in 1260. Khubilai wanted to hold the regime under Kim Jun in check, who was regarded as a potential risk, by supporting the royal family of Goryeo Dynasty, so that they could carry out the east-oriented policy in a stable way. The ‘Dong-Nyoung-bu’ was established unilaterally regardless of the intention of Goryeo. King Won-jong proposed intermarriage of royal families in both countries, trying to foster closer links with the Mongol, however, his proposals were not accepted as the royal family could not expel the political group led by Yim Yeon completely. The purposes of establishing ‘Dong-Nyoung-bu’ were as follows. Firstly, The Mongol tried to get a foothold for the east-oriented policy that could connect Nam-song, Yo-dong and Japan together, as well as secure a bridgehead through which it could hold a tight control over Goryeo. Secondly, the ‘Dong-Nyoung-bu’ was established in order to hold the three eastern royal families in Yo-dong Area in check, which were regraded as potential threat to Khubilai.

Unstable Expansion: The Development of the Military Medical Evacuation Chain in Korea, 1948–1953

강재구,박윤재 대한의사학회 2023 醫史學 Vol.32 No.2

This research examines the expansion and characteristics of the Korean Army’s chain of medical evacuation in 1948–1953. The most important goal of the chain of medical evacuation was to conserve fighting strength, which cannot be achieved only by sending the sick and wounded to the rear for treatment. It was more important to maintain as many mission-capable wounded soldiers on the frontline. Therefore, triage for conserving strength was the priority in the evacuation process, and military doctors conducting triage played a significant role. Focusing on military doctors, this article studies the instability of the Korean Army’s medical evacuation chain. Although Korea was liberated from Japanese colonial rule in August 1945, Korea had no army or army medical services. With the support of KMAG, the Korean Army was able to build a nationwide evacuation chain during the Korean War. However, the expansion of the medical evacuation chain resulted in instability. At the heart of the instability was manpower, rather than organization and transportation. Koreans had almost no experience with the military medical services before 1948, and during the Korean War, most doctors, who had been conscripted after the outbreak of the war, were not trained as military doctors. Therefore, the Korean Army had no other choice but to conduct medical evacuations using mobilized civilian doctors who were not sufficiently trained as military doctors. The escalating war revealed the problems of civilian doctors in military uniforms. Unlike the goal of the chain of medical evacuation, they easily evacuated patients and were reluctant to release patients to return to their duties. Korean Army doctors who were not sufficiently trained as military doctors struggled between the goals of military medical services and those of medical care. Consequently, the military doctors and the instability of the medical evacuation chain during the Korean War reflect the fundamental tension between war and medicine.

A Dynamic Power Consumption Estimation Method of Electro-mechanical Actuator for UAV Modeling and Simulation

강재구,권준용,이명섭 한국항공우주학회 2022 International Journal of Aeronautical and Space Sc Vol.23 No.1

The number of EMA (Electro-mechanical actuator)-based UAVs (unmanned air vehicle) are on the rise. The EMAs are generally applied to UAV as primary and secondary flight control surfaces actuator, speed or air brake actuator, door actuator, landing gears and so on. Since all EMAs are expressed as 2nd- or 3rd-order simplified mathematical models in M&S (modeling and simulation) phase, dynamic estimation of the EMAs power consumption is almost impossible and it causes battery/generator sizing problems in the design phase. Especially for UAVs that have all EMAs for the primary and secondary flight control actuators, electric power consumption is increased in flight because of hinge moments of the control surfaces caused by air pressure during flight. In this thesis, we provide a method for dynamic power consumption estimation of the primary and secondary control surface EMAs for M&S through the electro-mechanical dynamics and aerodynamics. Not only simulation results but also successful flight test results are presented in this work.

몽골의 高麗 北界 분리 시도와 東寧府의 편제

강재구 부경역사연구소 2016 지역과 역사 Vol.- No.39

The foundation of DongNyoungBu was a remarkable political point that separated the first half and the second half of King Wonjong in 1270. The impeachment of King Wonjong by Im Yeon provided Choi TanㆍHan Sin and Bukgye local politicians with a reason to arouse the military. It was also a turning point for Mongol Yuan Empire to separate Koryeo Bukgye. Koryeo Bukgye fell into the hands of Choi TanㆍHan Sin in the process and Mongol Yuan Empire completed the separation and established DongNyoungBu as Choi TanㆍHan Sin defected to Mongol Yuan Empire. As Dong-Nyoung-Bu got promoted to “Lo-ChongKwanBu”, DongNyoungBu got organized into NokSaSaㆍDoHoBuㆍJungWonBu. NokSaSa, which dealt with public administration from Dong-Nyoung Lo-ChongKwanBu, which was based in West capital. Darughachi was appointed and NokSaSa played a central role. DoHoBu was in “AnBuk DoHoBu” Young-Ju and JungWonBu was in “JungWon DoHoBu” Ku-Ju. In other words, DongNyoungBu was based in the main Bukgye area of West capitalㆍAnBuk DoHoBu Young-JuㆍJungWon DoHoBu Ku-Ju. Mongol Yuan Empire was directly in charge of West capitalㆍEui-Ju, the center of public administration and transportation as DongNyoungBu was embedded in the existing Bukgye administration system. Whereas, the Bukgye indigenous force, including the demoted Choi Tan, likely played a certain role in Ku-Ju[JungWonBu], their indigenous foundation. 1270년 동녕부 설치는 원종대 전ㆍ후반기를 가르는 중요한 정치적 사건이었다. 임연의 원종 폐위사건은 최탄ㆍ한신 등 북계 토착세력의 거병에 명분을 제공하였고, 몽골이 고려 북계를 분리하는 정책을 결정하는 데 계기가 되었다. 그 과정에서 고려 북계는 최탄ㆍ한신 등의 수중에 들게 되었고, 이들이 몽골에 귀부하면서 고려 북계 분리정책을 완수하여 동녕부를 설치하기에 이르렀다. 고려 북계가 분리되는 과정에서 보이는 북계민들의 민심은 고려로부터 이탈하고자 했던 최탄 등의 의도와는 달랐다. 최탄 등은 원종 복위와 임연 제거라는 명분에 의지하여, 북계민들을 동참시키는 것에는 성공했지만 그들을 반고려 정서로 결집하는 것에는 실패하였다. 하지만 최탄 등이 내세웠던 임연 제거라는 명분은 고려와의 강화 합의를 훼손시키지 않으면서도 고려 북계를 분리하기 위한 명분이 필요했던 몽골에 의해 승인하면서 고려의 반발 명분을 무력화시킬 수 있었다. 1275년 동녕부는 로총관부로 승격되었고, 녹사사ㆍ도호부ㆍ정원부의 체제로 편제되었다. 녹사사는 서경에 두어져 다루가치가 파견되는 등 중심적 역할을 수행하였다. 또한 도호부는 안북대도호부 영주, 그리고 정원부는 정원대도호부 구주의 지역적 토대 위에 편제되었다. 이 과정에서 서경ㆍ의주 등 행정ㆍ교통의 중심지는 몽골이 직할하는 한편, 최탄ㆍ한신 등 북계 토착세력은 그 지위가 강등되면서 주변화되면서 그들의 재지적 기반인 구주[정원부]에서 일정한 역할을 담당하였을 가능성이 크다.

고혈압성 소뇌출혈의 예후인자에 대한 고찰

강재구,최하영,김철진,김재은,이정청 대한신경외과학회 1992 Journal of Korean neurosurgical society Vol.21 No.3

1987년 1월부터 1990년 12월까지 4년동안 뇌전산화 단층촬영을 이용하여 진단받은 고혈압성소뇌출혈 28예를 대상으로 임상적 소견과 방사학적 소견, 그리고 예후를 분석한바 다음의 결론을 얻었다. 1) 사구체조의 모양이 정상인 경우 7예중 6예(85%)에서 좋은 예후를 보였다. 그중 수두증이 없었거나 출혈후 48시간내에 수두증에 대한 shunt시행을 받았던 5예 모두에서(1예에서만 혈종제거술 시행)좋은 예후를 보였다. 반면 48시간후 shunt 시행한 2예중 1예에서 좋은 예후를 보였다. 따라서 폐쇄성 수두증이 존재하면 조기에 이를 호전 시켜야 하며 혈종 제거술은 불필요한 것으로 여겨진다. 2) 사구체조가 부분 폐쇄된 경우 9예중 7예(78%)에서 좋은 예후를 보였다. 그 중 수두증이 없거나 출혈후 48시간내 수두증에 대한 shunt시행을 받었던 6예중 5예(83%)에서 좋은 예후를 보였으며, 혈종제거술을 함께 시행하였던 4예는 모두 좋은 예후를 보였으나, 혈종제거술을 시행치 않았던 2예중 1예에서만 좋은 예후를 보였다. 반면 48시간후 수두증에 대한 shunt를 시행한 경우는 3예중 2예(67%)에서만 좋은 예후를 보였다. 따라서 조기에 혈종제거술과 수두증이 있다면 48시간내에 shunt를 시행해 주는 것이 좋을 것으로 여겨진다. 3) 사구체조의 완전폐쇄된 경우 12예 모두에서 혈종제거술과 수두증 호전과 관계없이 좋지 않은 예후를 보였다. 4) 이상을 연구 결과 뇌 전산화 단층 촬영상 사구체조의 폐쇄정도는 환자의 예후에 대한 지침과 치료방법을 선택하는데 유용하다고 생각되었다. The authors analyzed 28 cases with hypertensive cerebellar hemorrhage, diagnosed by computerized tomography(CT), between 1987 and 1990, in Chonbuk National University Hospital. The authors assessed the relationship of outcome to the CT appearance of the quadrigeminal cistern, which in some cases was obliterated by rostral displacement of the vermis resulting from the cerebellar mass. Obliteration of the quadrigeminal cisterns was classified on the CT scans into three grades : Normal (Grade Ⅰ), Compressed (Grade Ⅱ), or Absent (Grade Ⅲ). There were 7 cases with Grade Ⅰ, 9 with Grade Ⅱ, and 12 with Grade Ⅲ cisterns. Of the 28 cases, 6(85%) of those with Grade Ⅰ, 7(78%) of those with Grade Ⅱ, and none of those with Grade Ⅲ cisterns respectively returned to their previous activities at 6 months or more after onset. A Grade Ⅰ cisterns predicted a good outcome whether the hematoma was evacuated or not, as long as obstructive hydrocephalus, if present, was relieved early. However, a Grade Ⅱ cisterns was not predictive of a good outcome unless the hematoma was evecuated within 48 hours after onset of the hemorhage. A Grade Ⅲ cisterns predicted an unfavorable outcome. Taken together, these results strongly suggest that the CT grade of quadrigeminal cistern obliteration may be an indicator of outcome and may be useful in selecting treatment for patients with cerebellar heorrhage.

Purpose: The purposes of this study were to identify factors affecting depression in college students and the correlation of depression with self-esteem and academic stress, and to identify differences among student self-esteem, academic stress, and general characteristics and the relationship of these variables to depression. Methods: The study was done in April 2011 with 852 students in health-related majors (medicine, nursing science, and dental hygiene) of a medical college in Korea. A self-rating survey containing 10 items from the Rosenberg Self-esteem Scale, 20 items from the Self-rating Depression Scale, and 22 items on academic stress was used. Data were analyzed using descriptive statistics, t-tests, one-way ANOVA, and logistic regression. Results: Medical students’ scores for self-esteem were significantly higher than dental hygiene students, but for academic stress scores, the result was the opposite. Logistic regression showed that self-esteem, academic stress, academic major and satisfaction with it (positive affect), and home income level (negative affect) significantly affected the level of depression. Conclusion: Designing and implementing realistic programs tailored to students' academic majors to enhance their self-esteem and provide practical knowledge in dealing with academic stress will help these students obtain a healthier school life emotionally as well as academically.

CJ-50001 (rG-CSF)에 대한 변이원성시험

강재구,백남진,김달현,하석훈,김제학,김현수 한국독성학회 1997 Toxicological Research Vol.13 No.3

In order to evaluate the mutagenic potential of CJ-50001 (recombinant human granulocytecolony stimulating factor), 3 sets of mutagenicity tests were performed. In the reverse mutation test using Salmonella typhimurium TA1535, TA1537, TA98 and TA100, CJ-50001 did not increase the number of revertant at any of the concentration tested in this study (500, 250, 125, 62.5 and 31.3 $\mu\textrm{g}$ plate). CJ-50001, at the doses of 200, 100 and 50 $\mu\textrm{g}$ /ml, did not increase the number of cells having structural or numerical chromosome aberration in cytogenetic test using Chinese Hamster Lung cells. In mouse micronucleus test, no significant increase in the occurrence of micronucleated polychromatic erythrocytes was observed in ICR male mice intraperitoneally administered with CJ-50001 at the doses of 5, 2.5 and 1.25 mg/kg. These results indicate that CJ-50001 has no mutagenic potential in these in vitro and in vivo systems.
