민주열사 이한열의 삶과 그에게서 계승해야 할 정신

정종훈 한국대학선교학회 2024 대학과 선교 Vol.62 No.-

이한열 열사는 1966년 8월 29일 아버지 이병섭 씨와 어머니 배은심 씨의 2남 3녀 가운데 장남으로 태어났다. 그는 1987년 6월 9일 ‘고문살인 은폐규탄 및 호헌철폐 국민대회’ 출정을 위한 ‘범연세인총궐기대회’에 참가하던 중 최루탄에 맞아 쓰러졌고, 친구들의 부축을 받으며 세브란스 응급실로 옮겨져 의식을 잃었다. 이한열 열사는 중환자실에서 27일간 투병하던 1987년 7월 5일 새벽 2시 5분경 사망했고, 장례는 7월 9일 오전 8시 연세대학교에서 ‘애국학생 고(故) 이한열 열사 민주국민장’으로 치러졌다. 그때 그의 나이는 만 21세가 아직 되지 않았다. 이한열 열사는 부모에게는 사랑받는 자랑스러운 아들이었고, 친구와 선생님들에게는 모범생으로 인정받는 학생이었다. 후배들에게는 그들을 챙겨주는 다정다감한선배였고, 선배들에게는 연세대학교 차기 총학생회장으로 기대받는 후배였다. 사회적인 약자들에게는 친구가 되고자 했고, 한국의 민주화를 위해서는 결과적으로 불꽃이 되었던 민주인사였다. 이한열 열사는 자기성찰적인 삶을 살고자 했고, 사회적 약자들과 연대하는 삶을 살고자 했다. 이한열 열사는 모든 만남에 대해서 책임 있는 삶을 살고자 했고, 민주화를 향한 헌신과 열정의 삶을 살고자 했다. 그리고 이한열 열사는 기독교인으로서 기독교적인 정체성을 지니고 살고자 했다. 연세대학교는 이한열 열사와 오랜 기간을 동행했고, ‘이한열민주화운동기념사업회’ 설립을 통해 앞으로도 영원히 동행하고자 노력하고 있다. 이제 우리는 이한열 열사의 불꽃 같은 인생을 직시하며, 오늘의 젊은이들과 연세가 계승하고 발전시켜야 할 정신이 무엇인가를 논구할 필요가 있다. 인권과 민주주의의 실현을 위해서 자신을 희생하는 ‘한 알의 밀알’의 정신, 역사의 아픔을 직시하며 불의에 침묵하지 않는 저항의 정신, ‘신앙과 삶’, ‘앎과 삶’의 일치를 추구하는 신행합일(信行合一)과 지행합일(知行合一)의 정신, 고통에 몸부림치는 사회적인 약자들과 소수자들에 대한 연대의 정신 등이 그에게서 계승해야 할 정신이라 여겨진다. Martyr Lee Han-yeol was born on August 29, 1966, as the eldest of two sons and three daughters to his father, Lee Byeong-seop, and his mother, Bae Eun-sim. On June 9, 1987, while participating in the ‘Pan-Yonsei Rally’ to campaign for the ‘National Rally to Condemn the Cover-up of Torture and Murder and Change the Constitution’, he was hit by tear gas and collapsed. He was taken to the Severance Emergency Room with the support of his friends, where he lost consciousness. Martyr Lee Han-yeol died at around 2:05 a.m. on July 5, 1987, after fighting for 27 days in the intensive care unit, and his funeral was held at Yonsei University at 8 a.m. on July 9 with the ‘National Burial for the Late Patriotic Student Lee Han-yeol’. At that time, he was not yet 21 years old. Martyr Lee Han-yeol was a proud son who was loved by his parents, and a student recognized as a model student by his friends and teachers. To his juniors, he was a kind and gentle senior who took care of them, and to his seniors, he was a junior who was expected to be the next student council president at Yonsei University. He wanted to be a friend to the socially underprivileged, and was a democratic figure who ultimately became a spark for Korea’s democratization. Martyr Lee Han-yeol aspired to live a self-reflective life in solidarity with the socially underprivileged. Martyr Lee Han-yeol wanted to live a life of responsibility for all his encounters, and to live a life of dedication and passion for democratization. And as a Christian, Martyr Lee Han-yeol tried to live with a Christian identity. Yonsei University has accompanied martyr Lee Han-yeol for a long time, and plans to continue to do so forever through the establishment of the ‘Lee Han-yeol DemocratizationMovement Memorial Association.’ Now, we need to look squarely at the fiery life of martyr Lee Han-yeol and discuss what spirit today’s young people and Yonsei University should inherit and develop. The spirit of ‘a grain of wheat’ that sacrifices itself for the realization of human rights and democracy, the spirit of resistance that faces the pain of history and does not remain silent against injustice. The spirit of unity of faith and action, unity of knowledge and action, and the spirit of solidarity toward the socially underprivileged and minorities struggling in pain are the spirits that must be inherited from him.

수열합성법으로 성장된 ZnO 나노로드 가스 센서의 제작 및 특성 연구

정종훈,유일,Jong, Jong-Hun,Yu, Il 한국재료학회 2011 한국재료학회지 Vol.21 No.4

ZnO nanorods for gas sensors were prepared by a hydrothermal method. The ZnO gas sensors were fabricated on alumina substrates by a screen printing method. The gas-sensing properties of the ZnO nanorods were investigated for $CH_4$ gas. The effects of growth time on the structural and morphological properties of the ZnO nanorods were investigated by X-ray diffraction and scanning electron microscope. The XRD patterns of the nanocrystallized ZnO nanorods showed a wurtzite structure with the (002) predominant orientation. The diameter and length of the ZnO nanorods increased in proportion to the growth time. The sensitivity of the ZnO sensors to 5 ppm $CH_4$ gas was investigated for various growth times. The ZnO sensors exhibited good sensitivity and rapid response-recovery characteristics to $CH_4$ gas, and both traits were dependent on the growth time. The highest sensitivity of the ZnO sensors to $CH_4$ gas was observed with the growth time of 7 h. The response and recovery times were 13 s and 6 s, respectively.

허혈이 유발된 흰쥐 해마에서 Norepinephrine 유리에 미치는 Adenosine 수용체의 역할

정종훈,최봉규,Chung, Jong-Hoon,Choi, Bong-Kyu 대한약리학회 1996 대한약리학잡지 Vol.32 No.2

The effects of adenosine analogues on the electrically-evoked norepinephrine(NE) release and the influence of ischemia on the effects were studied in the rat hippocampus. Slices from the rat hippocampus were equilibrated with $0.1{\mu}M$ $[^3H]-norepinephrine$ and the release of the labelled product, $[^3H]-NE$, was evoked by electrical stimulation(3 Hz, 2 ms, 5 $VCm^{-1}$ and rectangular pulses for 90 sec), and the influence of various agents on the evoked tritium-outflow was investigated. Ischemia(15min with 95% $N_2$ +5% $CO_2$) increased both the basal and evoked NE release. These increases were abolished by addition of glucose into the superfused medium, and they were significantly inhibited either by $0.3\;{\mu}M$ tetrodotoxin pretreatment or by removing $Ca^{++}$ in the medium. MK-801$(1{sim}10\;{\mu}M)$, a specific NMDA receptor antagonist, and glibenclamide $(1\;{\mu}M)$, a $K^+-channel$ inhibitor, neither alter the evoked NE release nor affected the Ischemia-Induced increases in NE release. However, polymyxin B(0.03 mg), a specific protein kinase C inhibitor, inhibited the effect of ischemia on the evoked NE release. Adenosine and $N^6-cyclopentyladenosine$ decreased the NE release in a dose-dependent manner in ischemic condition, though the magnitude of inhibition was far less than those in normal (normoxic) condition. Also the treatment with $5{\mu}M$ DPCPX, a potent $A_1-adenosine$ receptor antagonist did not affect the ischemia-effect. These results suggest that the evoked-NE release is potentiated by ischemia, and this process being most probably mediated by protein kinase C, and that the decrease of NE release mediated through $A_1-adenosine$ receptor is significantly inhibited in ischemic state.

만성 신부전 환자의 선단 궤양

정종훈,김성환,김영조,차윤정,정재헌,장정환 대한혈관외과학회 2000 Vascular Specialist International Vol.16 No.2

Calciphylaxis has been described as a rare condition in patients with end-stage renal disease and secondary hyperparathyroidism. Selye et al. First coined the term calciphylaxis to describe soft-tissue calcification and cutaneous necrosis. The common manifestation include painful digital necrosis and medial calcification of small and medium sized vessels. Calciphylaxis is a clinical diagnosis and is characterized by painful, violaceous, mottled skin lesions. Radiographic studies reveal calcification of median and small vessels under the knee but vascular calcification is not specific for calciphylaxis. Histolopathologic findings show a markedly reduced lumen, secondary to the fibrin deposition and inflammation in and around the outer media with an outer ring of calcification which leads to progressive ischemic tissue necrosis. Kidney transplantation and parathyroidectomy is recommened but it is controversial. We present the case of a 64-years-old man with chronic renal failure as well as painful ischemic necrosis on the lower extremity. The pertinets literature is reviewed.

Recently, it is increasingly necessary to run high-end neural network applications with huge computation overhead on top of resource-constrained embedded systems, such as wearable devices. While the huge computational overhead can be alleviated by distributed neural networks running on multiple separate devices, existing distributed neural network techniques suffer from a large traffic between the devices; thus are very vulnerable to communication failures. These drawbacks make the distributed neural network techniques inapplicable to wearable devices, which are connected with each other through unstable and low data rate communication medium like human body communication. Therefore, in this paper, we propose a distributed neural network partitioning technique that is resilient to communication failures. Furthermore, we show that the proposed technique also improves the inference accuracy even in case of no communication failure, thanks to the improved network partitioning. We verify through comparative experiments with a real-life neural network application that the proposed technique outperforms the existing state-of-the-art distributed neural network technique in terms of accuracy and resiliency to communication failures.

Bi를 첨가한 백색 LED용 ZnS:Mn 황색형광체의 발광특성

정종훈,유일,Jung, Jong-Hun,Yu, Il 한국재료학회 2011 한국재료학회지 Vol.21 No.1

Bi co-doped ZnS:Mn,Bi yellow phosphors for white light emitting diodes were prepared by the conventional solidstate reaction method. The optical and structural properties of ZnS:Mn,Bi phosphors were investigated by x-ray diffraction, scanning electro microscopy and photoluminescence. ZnS:Mn,Bi phosphors showed XRD patterns of hexagonal structure. The photoluminescence of ZnS:Mn,Bi phosphors showed spectra extending from 480 to 700 nm, peaking at 580 nm. The photoluminescence of 580 nm in the ZnS:Mn,Bi phosphors was associated with the 4T1 ${\rightarrow}$ 6A1 transition of the Mn2+ ions. The highest photoluminescent intensity of the phosphors under 405 nm and 450 nm excitation was obtained at Bi concentration of 7mol%. The optimum mixing conditions with epoxy and yellow phosphor for white light emitting diodes were observed in a ratio of epoxy:yellow phosphor of 1:3.5. The CIE chromaticity of the white LED at the 1:3.5 ratio was X = 0.3454 and Y = 0.2449.
