          김기택 시에 나타난 육식의 윤리와 아이러니

          홍기정(Hong, Ki-Jung) 문학과환경학회 2013 문학과 환경 Vol.12 No.1

          In these days, meat diet is problematic issues in terms of health, environmental and ethical issues. Poets in Korea focus the meat diet issue as a life-threatening problem (bioethics), the topics they are interested in is how to deal with the ethical pressure after eating living animals. The poet, Kim, Ki-Taik, criticizes unethical human behaviors for eating meats. Once people consider animals just for a menu, we make ourselves light of the life, which might make feeling of guilty. Continuously, that feeling might link with the negative logics about meat diets. However, Kim, Ki-Taik does not go to that negative logic but he also agrees we as a human instinctually want meats. Ironically, his poetry point out the meat diet’s unethical aspects which cause a sense of guilty but people as a human have no choice but to accept the fact that people eat meats. Thus, Kim, Ki-Taik claims that these ironies are the same as human’s proof of guilt. He also insists that it is inappropriate for human to take the evidence of crime, even though human natural is fundamentally evil, he believes. He tries to interpret the irony of meat diet metaphysically, to understand the reconciliation between life and death.

          한국문화교육에서 한국인 가치관의 실증적 규명에 관한 연구

          홍기정 ( Hong Ki-jung ) 우리어문학회 2019 우리어문연구 Vol.64 No.-

          외국인을 대상으로 한 한국문화교육에서 가치관은 중요한 항목으로 다루어져 왔다. 그런데 가치관과 관련하여서는 자주 거론되어 온 하나의 문제가 있다. 그것은 현대 한국인의 가치관을 명확하게 규명하는 것이 매우 어렵다는 것이다. 지금까지 관련 교재들과 연구물들에서는, 집단주의 가족주의 권위주의 같은 것들을 한국인의 가치관으로 다뤄 왔다. 그러나 이것들은 이전 세대의 인접학문 학자들에 의해 포착된 한국인의 성격적 특징들로서, 매우 빠른 변화를 특징으로 하는 오늘날에도 여전히 한국인의 가치관으로서 제시되는 것은 문제가 있다. 게다가 그것은 특정한 학문적 관심이 바탕에 깔린 연구의 결과이므로, 외국인에게 현대 한국인의 가치관을 소개하고 가르치는 목적으로서는 적합하지 않은 것일 수 있다. 이에 더하여, 한국인의 가치관으로 거론되는 것들 상당수가 연구자 개인의 인생 경험에 기초한 경험적 직관에 따라 선택된 것이라는 점도 문제이다. 이 논문에서는 가치관 교육과 관련된 이러한 문제들을 지적하고, 대안으로서 <한국인의 의식·가치관 조사>와 <세계 가치관 조사>의 자료들을 활용하여 실증적인 방식으로 한국인의 가치관 규명을 시도한다. In Korean language education for foreigners, Korean culture education is an important part. And value education is an important part of Korean culture education. However, there is one problem with the value education. The problem is that it is difficult to clearly identify the values of Koreans. So far, several things have been repeatedly mentioned as Korean values: collectivism, familyism, and authoritarianism etc. It is something that sociologists have pointed to in the past as a social feature of Koreans. The question is, does it reflect the values of Koreans today? Another problem is whether it meets the purpose of educating foreigners. This is because it is the result of research originating from specific academic interests. It is also a problem that the values of the Koreans mentioned are not based on objective and empirical data. This paper points out these problems and suggests an alternative. It is to use two surveys in value education, ‘Korean Sense & Value Survey’ and ‘World Value Survey(WVS)’. This paper explains how Korean values can be identified based on these data.

          논문 : 딜라토미터를 이용한 STD11 공구강의 오스테나이징 및 템퍼링 열처리에 따른 치수 변화 이방성 연구

          홍기정 ( Ki Jung Hong ),강원국 ( Won Guk Kang ),송진화 ( Jin Hwa Song ),정인상 ( In Sang Chung ),이기안 ( Kee Ahn Lee ) 대한금속재료학회 ( 구 대한금속학회 ) 2008 대한금속·재료학회지 Vol.46 No.12

          Heat treatment is an important step for tool manufacture, but unavoidably generates dimensional distortion. This study investigated the continuous dimensional change and the anisotropic behavior of STD11 tool steel during austenitizing and tempering heat treatment especially using quenching dilatometer. Dilatometric results represented that the dimensional change along longitudinal direction was larger than that along transverse direction. Anisotropic phase transformation strain was produced in forged STD11 tool steel during heat treatment. Anisotropic dimensional change increased with increasing austenitizing temperature. After tempering, anisotropic distortion was partially reduced. FactSage thermodynamic equilibrium phase simulation and microstructural observation (FE-SEM, TEM) showed that large (7~80 μm) elongated M7C3 carbides could be formed along rolling direction. The resolution of elongated carbides during austenitizing was found to be related with the change of martensite transformation temperature after heat treatment. Anisotropic size change of STD11 tool steel was mainly attributed to large elongated carbides produced during rolling process. Using dilatometric and metallographic examination, the possible mechanism of the anisotropic size change was also discussed.

          논문: STD11 공구강의 열처리 온도에 따른 탄화물 거동

          홍기정 ( Ki Jung Hong ),송진화 ( Jin Hwa Song ),정인상 ( In Sang Chung ) 한국열처리공학회 2011 熱處理工學會誌 Vol.24 No.5

          Carbide precipitation and dissolution behavior at various temperatures during heat treatment has been studied in STD11 cold working die steel through confocal scanning laser microscopy, dilatometry, and X-ray diffraction analysis. The equilibrium phase diagram and phase fractions with temperature were calculated using a FactSage program. Confocal laser microscopic observation shows that α to γ transformation temperature was near 800℃, M7C3 carbides melted at 1245℃, and the melting temperature of STD11 was near 1370℃. XRD results shows that the M23C6 carbides dissolved in the matrix if austenitized at over 1030℃, while the M7C3 carbides remained up to 1200℃ but its amount was decreased. The calculated equilibrium phase diagram showed in a good agreement with experimental results on carbide dissolution and phase transformation temperatures.

          STD11 공구강의 열처리 치수변화 이방성에 미치는 제조 조건의 영향

          홍기정 ( Ki Jung Hong ),송진화 ( Jin Hwa Song ),정인상 ( In Sang Chung ) 대한금속재료학회 ( 구 대한금속학회 ) 2012 대한금속·재료학회지 Vol.50 No.1

          Forged and flat-bar rolled STD11 tool steel shows anisotropic dimensional change during heat treatment. The dimensional change in the rolling direction is larger than that in the transverse direction. The cause of the anisotropic dimensional change is that the steel is anisotropic in composition, microstructure and other properties. The decrease of anisotropic distortion in tool steel is important for making better precision cold working dies. In this study, the effect of ingot weight and hot rolling reduction ratio on the anisotropic dimensional change of STD11 during heat treatment has been studied. Dimensional change was evaluated by simulating a real heat treatment process, including gas quenching and tempering. Experimental results showed that all the rolled flat-bar products had anisotropic distortion to some degree, but the anisotropic distortion was reduced as hot rolling ratio increased. Ingot weight had a little effect on anisotropic distortion. Microstructural observation showed that the anisotropic dimensional change of STD11 tool steel was closely related to the amount, shape and distribution of coarse carbides.

          원저 : 3차원 다중 채널 흉부 전산화 단층 촬영술을 이용한 중심정맥관 삽입의 적절한 길이

          홍기정 ( Ki Jeong Hong ),신중호 ( Jung Ho Shin ),박현수 ( Hyun Soo Park ),김성춘 ( Seong Chun Kim ),서길준 ( Gil Joon Suh ),이중의 ( Joong Eui Rhee ) 대한응급의학회 2007 大韓應急醫學會誌 Vol.18 No.5

          Purpose: Knowing the optimal length of central venous catheterization is important in order to prevent complications provoked by inappropriate placement of the tip of central venous catheter. We evaluated the optimal lengths of central venous catheterization using 3-Dimensional Multi-Detector Row Computed Tomography (MDCT). Methods: Between May 2005 and September 2005, we prospectively enrolled 122 consecutive patients who underwent elective chest MDCT. We reconstructed 3-dimensional MDCT images of the right internal jugular vein, right subclavian vein, left internal jugular vein, left subclavian vein and the superior vena cava/right atrium (SVC/RA) junction. In 3-dimensional images, we measured the distance from the puncture site of catheterization to the SVC/RA junction. In addition, we analyzed the correlation of the length of central vein to demographic findings, including patients` height, weight, body mass index, and body surface area (BSA). By regression modeling, we derived formulas to calculate the optimal lengths for central venous catheterization. Results: The optimal lengths of central venous catheterization via the right internal jugular vein, right subclavian vein, left internal jugular vein, and left subclavian vein were 12.9±1.5 cm, 14.0±1.5 cm, 15.9±1.9 cm, and 17.9±1.4 cm, respectively. The optimal length of right subclavian catheterization correlated significantly with body weight and BSA (p<0.01). The optimal length of left internal jugular approach correlated well with height (p<0.01), body weight, BMI, and BSA (p<0.005). Conclusion: The optimal lengths of central venous catheter were measured by 3-dimensional MDCT and correlated with demographic findings. By regression modeling, we developed formulas to predict the optimal length of central venous catheterization using based on demographic findings.

          응급실로 내원한 노숙인의 조기 결핵 선별을 위한 임상적 예측인자 연구

          백기봉 ( Ki Bong Baek ),신종환 ( Jonghwan Shin ),이휘재 ( Hui Jai Lee ),홍기정 ( Kijeong Hong ),정진희 ( Jin Hee Jeong ),이세종 ( Se Jong Lee ),정의기 ( Euigi Jung ) 대한응급의학회 2016 大韓應急醫學會誌 Vol.27 No.6

          Purpose: In 2014, Korea ranked as the first among the Organization for Economic Cooperation and Development countries on the prevalence, incidence, and mortality of pulmonary tuberculosis (TB). The prevalence of TB among the homeless was 6.4% in the United State and 7.1% in South Korea. The aim of this study is to develop predicting indicators of TB by analyzing homeless people who visit the public hospital emergency department (ED). Methods: We analyzed 7,500 homeless individuals who visited a public hospital ED between January 1, 2001 and May 31, 2014. A total of 4,552 patients were included, and of these, 145 homeless patients were infected with TB. We conducted univariate and multivariate analysis of clinical variables obtained from the initial check list and later lab analysis, and made a scoring system by weighing each variable. Then applying this scoring system, the area under the receiver (AUC) operating characteristic curve (ROC) was calculated. Results: The prevalence of TB was 3.2%. The initial meaningful predictor variables were as follows: Being homeless, abnormal heart rate, abnormal respiratory rate, no alcohol intake, hypoalbuminemia, and CRP elevation. The AUC of ROC curve from these predictor variables were 0.815. Conclusion: We developed a novel scoring system to screen TB patients in a vulnerable social group who visit the ED. We can detect potential TB patients early and effectively control TB, preventing the spread of TB. Prospective internal and external validation is necessary by using the scoring system of TB among the homeless.

          고수분 환경에서 미세먼지 실시간 측정을 위한 다공 튜브형 희석장치의 개발 및 성능 평가

          우창규,홍기정,김학준,김용진,한방우,안정언,강수지,천성남,Woo, Chang Gyu,Hong, Ki-Jung,Kim, Hak-Joon,Kim, Yong-Jin,Han, Bangwoo,An, Jeongeun,Kang, Su Ji,Chun, Sung-Nam 한국입자에어로졸학회 2017 Particle and Aerosol Research Vol.13 No.3

          본 연구에서는 고온희석-상온희석 2단 희석의 다공 튜브형 희석장치를 제작하여 실제 배기가스와 시험챔버의 다양한 고수분 환경에서의 희석 조건에 따른 응축성 물질의 생성 억제와 생성된 응축 입자의 제거 특성에 관하여 살펴보았다. 디젤 엔진의 배출 입자는 응축 성분의 핵화 모드와 고체상의 응축성장 모드의 이중모드 분포를 나타내었고, 다공 튜브형 희석장치의 1차 고온희석 유량을 증가시킴으로써 핵화 모드 입자의 생성을 억제시키고 응축성장 모드의 입자만을 측정할 수 있었다. 석탄보일러에서 배출되는 미세먼지에 대해서도 다공 튜브형 희석장치를 적용하여 응축성 성분의 입자 생성 없이 응축성장 모드의 입자만을 측정할 수 있었고, $3{\mu}m$ 크기 이상의 입자에 대해서 기존 이젝터 방식에 비해 상대적으로 입자 손실이 적음을 확인할 수 있었다. 또한 $30m^3$ 시험챔버에서 가습기로 인위적으로 발생시킨 물입자가 측정하고자 하는 고체 입자와 공존할 때 다공 튜브형 희석장치를 사용하여 물입자를 증발시켜 제거함으로써 고체 입자만을 정확하게 분리하여 측정할 수 있음을 확인할 수 있었다. Real-time measurements of fine particles from stack emission gases are necessary due to the needs of continuous environmental monitoring of PM10 and PM2.5. The porous tube dilutor using hot and cold dilutions was developed to measure fine particles without condensable particles from highly humid emission gases and compared to the commercialized ejector-type dilutor. Particle size distributions were measured at the emission gases from a diesel engine and a coal-fired boiler. The porous tube dilutor could successfully measure the accumulation mode particles including relatively large particles more than $3{\mu}m$ without nuclei particles, while the ejector dilutor detected some condensable particles and could not detect large particles. The porous tube dilutor could successfully remove the already condensed water droplet particles generated by a humidifier in a $30m^3$ chamber.

          초고속 유전자 증폭법을 이용한 벌집꼬마밑빠진벌레(Aethina tumida)의 신속한 검출 기법 개발

          김정민(Jung-Min Kim),임수진(Su-Jin Lim),Truong A Tai,홍기정(Ki-Jeong Hong),윤병수(Byoung-Su Yoon) 한국양봉학회 2017 韓國養蜂學會誌 Vol.32 No.2

          벌집꼬마밑빠진벌레 (Small hive beetle; SHB; Aethina tumida)의 신속검출과 대량 조사를 위하여 SHB 특이 초고속 유전자 증폭법을 개발하였다. 3쌍의 Aethina tumida-특이 유전자 증폭용 프라이머들은 벌집꼬마밑빠진벌레의 미토콘드리아 유전체 중 cytochrome oxidase subunit I (COI) 유전자에 근거하여 선발하였다. 최적화된 초고속 PCR은 2.1×10<SUP>1</SUP> 분자의 작은벌집딱정벌레 COI 유전자를 18분 40초만에 특이적으로 그리고 정량적으로 검출할 수 있었다. 양봉현장의 적용을 위하여, 봉변으로부터 쉽게DNA를 추출하는 방법을 고안하였으며, 봉변 1g 중 10<SUP>5</SUP> 분자의 벌집꼬마밑빠진벌레 COI 유전자가 존재할 경우(1/1000의 SHB 유충 사체), 10분 이내에 벌집꼬마밑빠진벌레의 존재와 분자적 정량을 마칠 수 있었다. 제안하는 이 실험법이 양봉현장에 널리 적용되어, 벌통 내 벌집꼬마밑빠진벌레의 침입여부 판단, 증식의 수준, 그리고 침입지역의 파악 및 제어에 활용되기를 기대한다. For the Rapid detection of small hive beetle (SHB; Aethina tumida) and for the mass-survey against SHB invasion, SHB-specific ultra-rapid PCR system was developed. Three different pairs of Aethina tumida-specific primers were deduced from cytochrome oxidase subunit I (COI) gene in mitochondrial DNA of SHB. Using optimized SHB-specific ultra-rapid PCR, 2.1×10<SUP>1</SUP> molecules of COI gene belonged to SHB could be detected specifically and quantitatively within 18 minutes 40 seconds. For the purpose of the application in apiary field, a DNA extraction method from bee debris was separatedly developed. When 10<SUP>5</SUP> SHB-specific COI molecules (1/1000 body of SHB larvae) are existed in 1g of bee debris, it could be verified inner 10 minutes as qualitative and quantitative manner. SHB-specific ultra-rapid PCR we proposed would be expected to apply widely, either in apiary field or laboratory, for the rapid detections and the control against SHBinvasion.
