Objective: Two famous medical doctors, Yoo Itae(以泰, 爾泰) and Riu Euitae(義泰), have been well known in academic world and public in Sancheong-gun. Yoo Itae is the progenitor of Majinhak which is the therapy for measles, he wrote a “Majinpyun” as the first book of therapy for measles in Chosun. Riu Euitae, meanwhile, is a fictional medical doctor and a teacher of Heo Jun who became real without confirmation of historical truths by Roh Jeongwoo who heard about a name, Yoo Itae. Roh`s assertion was quoted in the report of literatures, papers, novel, and telecast without verification. His assertion is exposed in novel and media and it has seriously distorted the history. The purpose of this study is to rectify the historical distortion. Methods: Various references study was performed. Confirmed a family tree, birth and death year, birthplace, sepulture, words on a tombstone, writing, collections of works anthology and the existence of keepsake. Investigated records of royal family, Sancheong-gun papers, Sancheong Hyanggyo papers, Dongyuhagan, Chosun Hanryuseungram and the record of Sawoo Munjip(anthology). Analyzed Roh Jungwoo`s conversation that tells Riu Euitae is a teacher of Heo Jun and contents of an encyclopedia. Listened to testimony of descendants and assertions of historian in rural area. Verified voice recording on books taken from at birthplace and the space of activity. Results: Yoo Itae is well shown in various records and medical writing books, whereas Riu Euitae does not. Riu Euitae is not a real person in the history. Roh Jeongwoo who asserts Riu Euitae is a teacher of Heo Jun admits his mistake. But, the encyclopedia record describing Riu Euitae is a teacher of Heo Jun, government official at Sancheong district office, historians in rural area, historians in rural area who made a family shrine, gravestone, a statue, memorial, historic site of Riu Euitae on Jinju Rui could not suggest any evidences for the existence of Riu Euitae and for record Riu Euitae is a teacher of Heo Jun. Conclusion : Riu Euitae is neither a real person in the history nor a teacher of Heo Jun. Riu Euitae came from pronunciation confusion between ‘I’ and ‘Eui’ in Kyungsang province. Riu Euitae is Yoo Itae on Geochang Yoo who was a medical doctor of King, Sukjeong and wrote medical books including <Majinpyun>, <Silheomdanbang>, <Inseomungyunrog>.

개선한 일회성 난수를 이용한 RFID 상호인증 프로토콜

윤은준(Eun-Jun Yoon),유기영(Kee-Young Yoo) 한국정보과학회 2009 정보과학회논문지 : 정보통신 Vol.36 No.2

2008년에 Kim-Jun은 의도하지 않은 정보의 누출로 인한 악의적인 공격들 및 범죄 악용 문제점들을 해결하기 위해 일회성 난수를 이용한 RFID 상호인증 프로토콜을 제안하였다. 보안성 분석을 통하여 Kim-Jun은 제안한 프로토콜이 재전송 공격을 포함한 다양한 공격들에 안전함을 증명하였다. 하지만 본 논문에서는 그들의 주장과는 달리 그들이 제안한 프로토콜이 여전히 재전송 공격에 취약함을 증명하며, 더 나아가 동일한 연산 효율성을 보장하며 재전송 공격을 막을 수 있는 간단히 개선된 일회성 난수 기반의 RFID 상호인증 프로토콜을 제안한다. In 2008, Kim-Jun proposed a RFID mutual authentication protocol using one-time random number that can withstand malicious attacks by the leakage of important information and resolve the criminal abuse problems. Through the security analysis, they claimed that the proposed protocol can withstand various security attacks including the replay attack. However, this paper demonstrates that Kim-Jun's RFID authentication protocol still insecure to the replay attack. In addition, this paper also proposes a simply improved RFID mutual authentication protocol using one-time random number which not only provides same computational efficiency, but also withstands the replay attack.

Preparation of mechanically enhanced supramolecular carbon nanotube (CNT) film using a water‑soluble π–π bonding linker

Jun‑Woo Lee,Moonseong Yoo,Kun Won Kim,Hyein Jeong,Jae Woo Chung 한국탄소학회 2019 Carbon Letters Vol.29 No.5

Mechanically enhanced supramolecular carbon nanotube (CNT) films were prepared in water by employing the π-electronrich phenyl, naphthalenyl, and pyrenyl end-functionalized polyethylene oxides (PEOs) as supramolecular linkers, followed by vacuum filtration. Among them, the supramolecular CNT film produced by the pyrenyl end-functionalized PEO (PEOPy) exhibited the highest mechanical strength, which was ~ 1.5–2 times higher than that of the CNT films produced using the typical dispersant, Triton X-100, although the functionality of PEO-Py was lower than that prepared using other linkers, and the content of PEO-Py in the CNT films was lower than that obtained using Triton X-100. Fluorescence and UV–Vis spectroscopy demonstrated that the improved mechanical properties of the supramolecular CNT film result from the formation of π–π interactions between the CNT and the pyrene moieties of the PEO-Py linker. Finally, the supramolecular CNT film exhibited a 40–50 dB electromagnetic shielding efficiency through hybridization with silver nanowires.

목적: 경골 원위부 골절의 치료에 있어 최소 침습적금속판 고정술과 관혈적 고정술에 대한 비교를 통한 효율성에 대한 연구고찰을 하고자 한다. 대상 및 방법: 2001년 6월부터 2004년 6월까지 경골 원위부 골절에 대하여 수술을 시행한 최소 1년 이상의 추시가 가능하였던 30예 중 최소 침습적 금속판 고정술을 시행한 15예를 A군, 관혈적 금속판 고정술을 시행한 15예를 B군으로 나누어 수술시간, 술 후 재활, 술 후 운동범위, 동통에 대하여 McLennan과 Ungersma의 기준을 이용한 임상평가, 술 후 염증반응에 대한 C-반응성 단백 및 술 후 합병증을 후향적으로 비교 분석하였다. 결과: A군과 B군의 수술시간은 각각 63분 (45∼105)/129분 (80∼120), 능동적 관절 운동가능시기는 8.3일 (6∼14)/15.8일 (13∼21), McLennan과 Ungersma의 기준에 의한 임상평가는 두 군 모두에서 대부분 양호 이상의 결과를 보였으나, B군에서는 보통 1예가 있었다. 술 후 3일, 7일째 각각 시행한 CRP는 A군에서는 4.0 mg% (범위: 0.9∼7.2)/0.5 mg% (0.1∼1.5), B군에서는 7.97 mg% (2.8∼14.6)/1.0 mg% (0.3∼1.6)로 A군에서 조직손상이 적고 회복이 빨랐다. 술 후 합병증으로는 A군에서는 표재성 감염 1예와 5도 이상의 족관절 외반변형 1예가 있었고, B군에서는 표재성 감염 1예, 감염성 불유합 1예와 10도 미만의 족관절 배굴장애를 보이는 경우가 2예 있었다. 결론: 경골 원위부 골절의 수술적 치료에서 최소 침습적 금속판 고정술이 관혈적 고정술에 비해 조직의 염증반응과 합병증이 적고 수술시간 및 술 후 재활 등에서 보다 효율적인 술식으로 사료된다. Purpose: To evaluate the efficacy of the surgical treatment through the comparison of MIPPO vs open plate fixation in the treatment of the distal tibia fracture retrospectively. Materials and Methods: 30 patients with distal tibia fracture from Jun. 2001 to Jun. 2004 were divided into two groups depending on the surgical method. Minimum follow up was 12 months. Group A consisted of 15 patients treated with MIPPO, Group B was 15 patients treated with open plate fixation. The clinical outcomes were evaluated retrospectively from operation time, rehabilitation, ROM, interval change of postoperative CRP to assess postoperative inflammatory reaction, postoperative complications and clinical result with the use of McLennan and Ungersma criteria. Results: There were no significant differences in clinical result by McLennan and Ungersma criteria in both groups. The postoperative 3 days and 7 days CRP were 4.0 mg% (0.9∼7.2)/0.5 mg% (0.1∼1.5) in group A and 7.97 mg% (2.8∼14.6)/1.0 mg% (0.3∼1.6) in group B, shows more minimal tissue injury and early recovery in group A. Operation time in group A was shorter than group B. Normal recovery of ROM was quicker in Group A. In complications, group A showed one superficial infection and one angular deformity and group B showed one superficial infection, one infected nonunion and two ankle stiffness. Conclusion: There were no significant differences in clinical result and bony union. MIPPO technique is superior to group B in view of the minimal tissue injury, complications, operation time and postoperative rehabilitation.

유승모,박준서,정하열,심재용,김병호,박장우 한국산업식품공학회 2003 산업 식품공학 Vol.7 No.4

The film with methylcellulose(MC) and grape seed extract(GSE) were prepared by casting their aqueous solution at 80℃ and drying at 23℃ for 48 hrs. Effect of grape seed extract(GSE) on the barrier permeabilities and the thermomechanical property of methylcellulose(MC) film was studied. The barrier permeabilities and the thermomechanical property of MC film containing various contents of GSE were evaluated in terms of water vapor, oxygen permeabilities, and dynamic mechanical analysis(DMA). The rate of water vapor permeability of MC film decreased with GSE contnets in the MC films. Also, the rate of oxygen permeability also decreased with GSE contents indicating higher oxygen barrier property of MC film. The results showed that GSE had a good miscibility with MC and acted as a plasticizer for MC film resuling in lowering the glass transition temperature of the film.

유소영,박찬영,정석,김동익,이병붕,허세호,한동철,장준근 대한혈관외과학회 2002 Vascular Specialist International Vol.18 No.2

Purpose: The spreading, orientation, and chemotaxis the gradient of a chemoattractant of smooth muscle cells (SMCs) were studied on the micro-grooved substrata by the light, fluorescence and scanning electron microscopy. Method: Vertical-walled grooves were produced in silicon wafers by the micromachining technique. All grooves were 4~20㎛ deep and 10~80㎛ wide, SMCs were cultured on each microgroove and examined under stereo-microscope. Result: Cell clusters were markedly oriented by all the grooved substrata examined. Tim-lapse images acquired from CCD (Charge Coupled Device) showed that the grooves directed the migration of SMCs. There was no prominent difference in the migration speed of SMCs according to the grooves. All the cytoskeletal fibers were reoragnized in the same direction with grooves. Especially the alignments of microtubule and intermediate filaments were distinguished in the SMCs on the micro grooves. Conclusion: These results could be applied to the analysis of vascular restenosis and the development of artificial blood vessels.

압박 고 나사로 치료한 대퇴골 전자부 골절 : 고정 실패의 인자에 대한 분석 Analysis of Factors associated with Failure of Fixation

유찬훈,김홍태,변영수,남준모,조영호,문성건 대한골절학회 2002 대한골절학회지 Vol.15 No.4

목 적 : 압박 고 나사로 치료한 대퇴골 전자부 골절의 고정 실패에 영향을 미치는 요소에 대하여 분석하고자 하였다. 대상 및 방법 : 1995년 5월부터 2000년 7월까지 대퇴골 전자부 골절을 압박 고 나사를 이용하여 치료하고 1년 이상 추시가 가능했던 97예를 대상으로 하였다. 골절의 분류는 Jensen 분류법을, 골다공증의 정도는 Singh 지수를 이용하였다. 술후 방사선 검사에서 경체각, 정복 상태, 지연 나사의 대퇴골 두 내 위치, tip-apex distance(TAD) 및 지연 나사의 활강 거리를 측정하였고 고정 실패에 미치는 영향을 통계학적으로 분석하였다. 결 과 : 97예 중 17예(17%)에서 고정 실패가 발생하였고 그 중 지연 나사의 과도한 활강으로인한 경우가 15례(15.4%), 골두 천공 1얘, 10도 이상의 외반 변형 1예였다. 고정 실패의 발생과 80세 이상의 고령, 불안정성 골절, telescoping 정복, 원위 골편의 내측 혹은 전방 전위, 대퇴골 두 내 지연 나사의 위치와 밀접한 관계가 있었다. 결 론 : 압박 고 나사를 이용한 대퇴골 전자부 골절의 치료에서 고정 실패를 방지하기 위해서는 정확한 정복이 필요하고 대퇴골 두 내에서 지연 나사의 전방 위치를 피하는 것이 좋을 것으로 사료된다. Purpose : This study was performed to analyze the significant factors that may affect failure of fixation in trochanteric fractures of the femur treated with the compression hip screw. Materials and Methods : From May 1995 to July 2000, the authors analyzed 97 cases of trochanteric fracture of the femur treated with the compression hip screw and followed more than one year. We classified the fracture type by Jensen's method. We used Singh index for the degree of osteroporosis. In the post-operative radiograph, we checked neck-shaft angle, state of reduction, position of the lag screw within the femoral head, tip-apex distance, and sliding distance of the lag screw. The relationship between these factors and failure of fixation was statistically analyzed. Results : There were 17 cases(17.5%) of failure of fixation ; 15 cases(15.4%) of excessive sliding of the lag screw, 1 case (1%) of cutting out of the lag screw, and 1 case (1%) of valgus malunion. There were significant relationship between failure of fixation and old age over 80 , unstable fracture, telescoping reduction, anterior or medial displacement of the distal fragment, and anterior placement of the lag screw within the femoral head. Conclusion : Accurate reduction and avoidance of the placement of the lag screw in the anterior part of the femoral head were important factors to prevent failure of fixation in trochanteric fractures of the femur treated with the compression hip screw.
