이훈구 연세대학교 인문과학연구소 2004 인문과학 Vol.86 No.-

이 연구는 남녀간의 배우자 자질의 중요성 평가상에 차이가 있고 이는 진화론적 사회심리학 이론으로 설명할 수 있다는 가설을 검증하려는 목적으로 수행되었다. 조사대상자는 남자 168명과 여자 140명 도합 308명이었다. 13가지의 자질을 평정법과 등위법을 사용하여 피험자로 하여금 각 자질의 중요성을 평가하게 했다. 결과를 보면 남자는 '신체적 매력'을 중요시한 반면 여자는 '경제적 능력이 있음'을 중요시하였다. 이 결과는 가설을 긍정하는 것이다. 이 조사의 결과를 세계 37개국의 결과와 비교하여 한국과 다른 문화권과의 차이를 살펴보았다. 이 연구의 특징과 추후 연구시 고려해야할 사항을 토의했다.

This study was performed to investigate the type of extended-spectrum $\beta$-lactamases (ESBL) produced by bacteria isolated from the sewage of wastewater treatment plant at Minragdong, Suyong-gu in Busan. The facility is located at sushi restaurants and guides its drain water to the wastewater treatment plant at Yonghodong, Nam-gu in Busan. Samples were collected on January, 2009. A total of 19 strains were selected as potential ESBL positive strains through a double disk synergy test. On the basis of the results from biochemical tests including indole, methyl-red, Voges-Proskauer, Simmon's citrate, decarboxylase-dihydrolase and sugar-fermentation tests, the 19 strains were identified with 16 strains of Escherichia coli and 3 strains of Klebsiella pneumoniae. Out of 19 strains, 4 transconjugants against Escherichia coli J53, which is sodium azide resistant recipient strain, were obtained. The plasmids isolated from transconjugants were used for PCR analysis. The type of each extended-spectrum $\beta$-lactamase (ESBL) produced by the strains was determined on the basis of isoelectric focusing analysis and DNA sequencing. The results indicated that the types of ESBL from Klebsiella pneumoniae were SHV-12 (3 strains), and Escherichia coli was SHV-12/TEM-1 (1 strain), respectively.

복음서에 나타난 예수 그리스도의 개인전도 사례연구

이훈구 한국복음주의선교신학회 2010 복음과 선교 Vol.13 No.-

The Korean churches began its movement starting 1960’s. It grew rapidly entering 1970’s, and in 1980’s, it made a remarkable church revival of over ten million believers. But entering 1990’s,the church growth began to show a declining curve and in 2000’s,it either made a staggering or minus growth and the number of believers lowered to 8.5 million. Although churches gather various evangelism methods to grow churches again, the reality is that there is no particular alternative available. According to the survey of 14,000 people conducted by Institute for Church Growth on the topic of Which Method Maximize Church Growth, personal evangelism by friends, relatives, and neighbors make up 75 to 90 percents. The survey is classified into different categories: 1) relation evangelism by friends, relatives, and neighbors makes up 75 to 90percents 2) pastors makes up 5 to 6 percents 3) Sunday schools makes up 4 to 5 percents 4) church programs makes up 2 to 3 percents 5) 2-3% through volunteer walk-in makes up 2 to 3percents 6) house visits makes up 1 to 2 percents 7) special needs makes up 1 to 2 percents 8) evangelism conferences makes up 0.5percents. Personal evangelism is a method used by Jesus Christ two thousand years ago, and it is the last alternative of evangelism for this era. Personal evangelism was present in the Old Testament. Eliezel,a servant of Abraham did personal evangelism to Rebecca and her elder brother Laban in Paddan Aram, Joseph who was sold to Egypt by his own brothers did to the government officials who committed sins and imprisoned and the King Pharaoh, the girl captivated to Aram did to the Commander Naaman who was suffering from leprosy, and prophets also did personal evangelism. In the New Testament, Jesus came to the earth as a messiah and showed a good example of personal evangelism through his public life. Jesus gathered twelve disciples through personal evangelism, and saved Nicodemus who visited him at night, the woman who was living in Sychar but walked to Jacob’s well to draw water,Zaccheus, a short and reach chief tax collector who wanted to meet Jesus passing through Jericho through personal evangelism. When Jesus was doing personal evangelism, he used methods of choice, contact, seizing opportunity, assurance on the truth, and power. Whether it is an alternative for church growth, evangelism, or anything else, the answer is the bible and Jesus Christ. Many churches and pastors are tired of, exhausted by, and fed up by numerous church growth programs flooding churches and yet, do not last, various evangelism programs and strategies. The last way for Korean churches to revive is personal evangelism that Jesus Christ set a good example of. I only hope and pray that Korean churches revive applying personal evangelism that Jesus showed to us instead of wasting time and energy looking for alternatives from far away.

선형터빈 익렬의 익단간극유동에 대한 수치해석적 연구

이훈구,유정열,Lee, Hun-Gu,Yu, Jeong-Yeol 대한기계학회 1997 大韓機械學會論文集B Vol.21 No.6

Three-dimensional turbulent incompressible flow through the tip clearance of a linear turbine rotor cascade with high turning angle has been analyzed numerically. As a preliminary study to predict the tip clearance loss realistically, a generalized k-.epsilon. model derived by RNG (renormalized group) method is used for the modeling of Reynolds stresses to account for the strain rate of turbulent flow. The effects of the tip clearance flow on the passage vortex, the total pressure loss are considered qualitatively. The existences of vena contract and tip clearance vortex have been confirmed and it has been shown that as the size of the tip clearance increases, the accumulated flow through the tip clearance and the total pressure loss downstream of the cascade increase.

전향각이 큰 선형터빈 익렬을 통하는 난류유동의 수치해석

이훈구,유정열,윤준원,Lee, Hun-Gu,Yu, Jeong-Yeol,Yun, Jun-Won 대한기계학회 1996 大韓機械學會論文集B Vol.20 No.12

A numerical analysis on three dimensional turbulent incompressible flows through linear cascades of turbine rotor blades with high turning angles has been performed by using a generalized k-.epsilon. model which is a high Reynolds number form and derived by RNG(renormalized group) method to account for the variation of the rate of strain. A second order upwind scheme is used to suppress numerical diffusion in approximating the convective terms. Body-fitted coordinates are adopted to represent the complex blade geometry accurately. For the case without tip clearance, velocity vectors and static pressure contours are shown to be in good agreement with previous experimental results. For the case with tip clearance, the effects of the passage vortex and tip clearance flow on the total pressure loss as well as their interactions are discussed.

Blood Stream Infections in Patients in the Burn Intensive Care Unit

이훈구,장주아,최정은,정두철,한정완,우흥정,전욱,천병철 대한감염학회 2013 Infection and Chemotherapy Vol.45 No.2

Background: The study on bacteremia helps empirically select the proper antibiotics before the results of culture test about causative pathogen. The purpose of this study is to investigate causative pathogen in bloodstream infection, changing aspects based on elapsed time after burn, relationship with other sites and resistance of important causative pathogen against antibiotics through analysis on bacteria isolated from blood culture of patients hospitalized in burn intensive care unit (BICU). Materials and Methods: A retrospective study was conducted targeting patients hospitalized in BICU from January 2007 to June 2011. Changes of causative pathogen in bloodstream infection based on elapsed time after injury were analyzed. We would like to examine the relationship between bloodstream infection and infection on other body parts by comparing results of cultures in burn wound site, sputum, urine and catheter tip. Antibiotics resistance patterns of Pseudomonas aeruginosa, Acinetobacter baumannii, Staphylococcus aureus, Enterococcus species, and Klebsiella pneumoniae were studied. Results: A total of 2,337 burn patients were hospitalized in BICU for 54 months. Causative pathogen was cultured in blood cultures from 397 patients (17.0%). P. aeruginosa (169, 30.1%) was the most cultured and A. baumannii (107, 19.0%) and S. aureus (81, 14.4%) were followed. It was confirmed that the relative frequency of A. baumannii tended to get lower as the period got longer after injury, but the relative frequency of K. pneumoniae got higher as the period got longer after injury. With comparison without bacteremia, P. aeruginosa bacteremia showed high probability in which the same bacteria were cultured in wound site, sputum and cathether tip, and A. baumannii bacteremia and candida bacteremia had high probability in sputum,and urine and catheter tip, respectively. 95.9% of P. aeruginosa and 95.3% of A. baumannii showed the resistance against carbapenem. 96.3% of S. aureus was methicillin resistant and 36.2% of Enterococcus species were vancomycin resistant. 75.0%of K. pneumonia were extended-spectrum beta-lactamase (ESBL)-producing bacteria. Conclusions: Since the highly antibiotic resistant microorganisms were isolated from the patients hospitalized in BICU during early phase, the empirical selection of antibiotics targeting these pathogens should be considered before the results of microbiologic culture test. In addition, use of empirical antifungal agent after 1 week of injury can be considered for patients who have risk factor of fungal infection.

비소세포폐암에 동반된 크롬세포친화종 치료 1예

이훈구,장주아,최정은,김철홍,현인규 대한내과학회 2011 대한내과학회 추계학술발표논문집 Vol.2011 No.1

서론: 절제가능한 비소세포폐암의 4~8% 정도가 편측 부신비대를 동반한다고 알려져 있고, 이 중 26~40% 정도가 악성이라고 알려져 있다. 하지만 비소세포폐암과 편측 부신 종괴가 동반되어 있을 경우, 다른 검사를 하지 않는 상태에서 이 종괴를 악성으로 단정지을 수 없으며, 오히려 양성으로 판명되는 경우가 더 많다. 보통, 경피적 세침흡인생검법이 이러한 경우의 치료법을 확립하는데 도움이 된다. 증례: 5년 전고혈압 진단받고 약제 복용 중이던 59세 여자환자가, 3년 전 정기검진에서 시행받은 흉부 방사선사진에 우상엽 부위의 간유리음영(ground-glass opacity) 발견되어 흉부 방사선사진의 변화양상을 경과관찰하다가 내원 며칠 전 촬영한 흉부 방사선사진에서 이전과 변화된 양상의 간유리음영 보여 검사 위해 내원하였다. 내원시 혈압은 110/70 mmHg, 맥박은 64회/분이었다. 우상엽 부위를 전산화단층촬영-유도 경피적세침흡인법 시행하였고, 폐선암 (기관지 폐포암 (Bronchoalveolar carcinoma)) 진단하였다. 병기설정 위해 양전자방출단층촬영(PET CT) 시행하였고, 우측 부신에 국소적으로 강한 대사활성 소견 보여, 폐암의 전이 또는 일차적 부신 종양의 가능성 모두 배제할 수 없는 상태였다. 본원 비뇨기과 협진하여 부신의 병리학적 검사 시도하였으나 접근이 어려운 관계로 호르몬검사 시행하였고, 레닌이 2.6 ng/ml/hr로 증가되어있는 소견 외에 다른 호르몬 검사는 정상 범위였다. 부신 선종으로 보고, 비뇨기과에서 로봇-복강경 부신절제술 (Robotic assisted laparoscopicadrenalectomy) 시행하였고, 일주일 이후 기관지 폐포암에 대하여 흉부외과에서 비디오흉부수술(VATS) 시행하였다. 로봇 수술과 함께, 외과적 조직검사(surgical biopsy) 시행하였고, 면역조직화학염색검사(immunohistochemical stain)에서 Chromogranin A 양성 소견 보여, 크롬친화세포종 확진하였다. 결론: 이 증례는 폐암 환자에서 부신의 종양이 동반되어 있을 경우, 부신의 병변에 대한 확실한 진단을 얻는 것의 중요성을 대변한다. 증례에서, 부신에 대한 경피적 세침흡인생검은 시행하지 못하였지만, 호르몬 검사와 외과적 조직검사로 양성 종양임을 확진하였고, 결과적으로 적절한 치료가 이루어졌음을 보여 준다.
