        박세채(朴世采, 1631∼1695)의 이이(李珥) 문집 편찬과 그 특징

        오세현(Oh Se-hyun) 부산대학교 인문학연구소 2020 코기토 Vol.- No.92

        박세채는 어린 시절부터 이이의 학문과 인품을 존경했고, 이이의 문집 초간본이 간행된 이후 그 초간본의 부족함에 대해 문제의식을 갖고 있었다. 다양한 분야에서 선현들의 학문적 성과를 정리하는 일에 매진했던 박세채는 이이의 학문을 선양하기 위한 목적에서 이이의 문집 초간본을 보완하는 작업을 진행했다. 그런데 사실의 측면에서 다양한 자료의 수집과 축적을 목표로 했던 박세채의 활동이 송시열에게는 전혀 다르게 인식되었다. 그것은 사실보다는 학문적 계통의 정비와 내적 단결을 위해 당위의 측면을 강조했던 송시열의 지향의 차이에서 비롯되었다. Park Se-chae has admired Yi-i’s academics and character since childhood. After the first copy of Yi-i’s writings was published, he had a problem with the lack of the first book. He devoted himself to organizing the academic achievements of the senior confucian scholar in various fields, and worked on supplementing the first draft of Yi-i’s writings with the aim of advancing the study of Yi-i. In terms of facts, Park Se-chae’s activities aimed at collecting and accumulating various data were perceived completely differently by Song Si-yeol. It originated from the difference in the intention of Song Si-yeol, who emphasized the aspect of the reason for the maintenance of the academic system and internal unity rather than the facts.

        미국의 항공운송산업 규제완화법(Airline Deregulation Act of 1978)이 미국의 공항 경제에 미친 영향에 관한 연구

        오세현 한국항공운항학회 1994 한국항공운항학회지 Vol.2 No.-

        미국의 항공운송산업 규제완화법(Airline Deregulation Act of 1978)에 의한 미국의 항공 운송산업 자유화 정책은 미국의 국내 항공운송 시장의 환경을 철저한 경쟁의 원리가 적용되는 자유경쟁 시장으로 변화시켰으며, 국제 항공운송 시장에도 자유경쟁의 원리가 점진적으로 도입되는 계기를 마련하였다. 항공운송산업 자유화 정책은 항공사의 운송 시장 환경뿐만 아니라 그들이 이용하는 공항의 경제 화경에도 많은 변화를 가져왔다. 자유화가 공항의 경제에 미친 영향을 연구하기 위하여, 자유화 이후 공항에서 시장 합리화(Market Rationalization)의 원리가 적용 되었는가를 조사하였다. 이를 위해 (1) 자유화 이후, 공항료(Airport Rates and Charges)와 공항에서의 활동량(the Volume of Activity) 간에 유의한 상관 관계가 존재하는 가의 여부 (2) 자유화 이전과 이후를 비교할 때, 각 Hub Class별 공항료의 수준에 있어 유의한 변화가 있는 가의 여부에 대한 통계 분석을 실시하였다. 상관 분석의 결과, 자유화 이후, 공항료와 공항에서의 활동량 간에 유의한 상관 관계가 존재한다는 결론을 채택하는 데 실패하였으며 또한 일원 분산 분석의 결과, 자유화 이전과 이후를 비교할 때, 각 Hub Class별 공향료의 수준에 있어 유의한 변화가 있다는 결론을 제시할 수 없었다. 미국의 항공운송산업 자유화 정책이 미국 공항 경제에 미친 영향에 대한 본 연구는 현재 경제규제완화를 실험하고 있는 우리의 경제 정책에 좋은 참고 자료가 되기를 기대한다.

        백서의 심실세동성 심정지 모델에서 해마신경세포 손상에 대한 단백질 합성저해제의 효과

        오동렬,채장성,박승현,김세경,최세민,박제영 대한응급의학회 2000 대한응급의학회지 Vol.11 No.4

        Background: The goal of successful resuscitation is not only to stop the process of ischemia as soon as possible but also to overcome the secondary injury process after resuscitation, which involves a complex interplay of mechanisms. Brain damage accompanying cardiac arrest and resuscitation is frequent and devastating. Cells die by one of two mechanisms: necrosis or delayed neuronal death. Delayed neuronal death may require protein synthesis. Neurons in the CA1 subfield of the hippocampus are selectively vulnerable to death after injury by ischemia and reperfusion. Death of these neurons occurs after an interval of 1 or 2 days. We assessed the effects of a protein synthesis inhibitor, cycloheximide(CHX), on hippocampal neuronal death of rats by using the ventricular fibrillation cardiac arrest(VFCA) model. Methods: The effect of CHX(3 mg/kg, s.c.) on hippocampal neuronal death was studied in two groups of 18 rats each, one group being subjected to a 2-min VFCA and the other to a 3-min VFCA. Each group was divided into three subgroups: control(groupⅠ,Ⅱ) without subcutaneous injection of CHX, "esp-12" of group Ⅰ/Ⅱ treated with CHX 12 hours after return of spontaneous circulation (ROSC), and "exe-24" of group Ⅰ/Ⅱ treated with CHX 24 hours after ROSC. The coronal sections of the hippocampus levels were stained with hematoxylin-eosin after 72 hours of survival. The histologic damage score(HDS) was used to assign a score to the total number of damaged neurons counted in each of the hippocampal CA1 subfields. Results: 1. There were not significant differences in heart rates, blood pressures, blood sugar, and blood gas in group I & Ⅱ during the pre-arrest steady state or at 5 min and 30 min after ROSC. 2. In group I & Ⅱ, the HDS, were significantly reduced in rats(I exp-12, 1.1 ±0.6;Ⅰexp-24, 1.3 ±0.5;Ⅱ exp-12, 1.4±0.7; and Ⅱ exp-24, 1.8±0.8) treated with CHX 12 hours or 24 hours after ROSC than control rats(1,2.5 ±0.9;Ⅱ,2.9±0.8)(p<0.05). Conclusion: These results suggest that delayed hippocampal neuronal death from ischemic insult after ventricular fibrillation cardiac arrest followed by resuscitation can be prevented by a protein synthesis inhibitor, CHX. Further experimental studies of the action mechanism of protein synthesis inhibitors to delayed neuronal death and clinical applications are required.

        응급환자 의료정보의 공유 현황과 개선방안

        오세현,이부수,김병철,김원,임경수 대한응급의학회 2001 대한응급의학회지 Vol.12 No.4

        Background: To manage the EMS(emergency medical services) system effectively, departments, such as fire stations, emergency information centers, hospitals, and The Ministry of Health and Welfare, should exchange information that they own and/or gather during patient care and/or transportation. Medical records and information are very important for continuing the patient's care and for deciding on a treatment plan, but medical information is not exchanged fully in spite of its importance. Method: We analyzed the transfer medical reports that were written by medical doctors who transferred emergency patients to our hospital. The contents and the accuracy of the transfer medical records were analyzed and graded into 4 groups. Group A was fully described and was equipped with diagnosis, laboratory data, X-ray fi1ms; group B had a diagnosis and full laboratory data; group C had a diagnosis, but only partial laboratory data; and group D had only a diagnosis. Results: Among 38,214 patients who visited our hospital from Jan. 2001 to Jun. 2001, 7,031 cases were transferred from other hospitals with transfer medical records. According to the accuracy and important contents of the transfer records, Group A occupied 1.9%, group B 5.2%, group C 32.5%, and group D, with only a diagnosis,60.4%. In the case of our hospital, we delivered all emergency medical information by written paper(transfer note), E-mail, and web-based information system(caber-AMC) to the doctors concerned with managing the patient. However, 93% of the medical records of patients transferred from other hospital contained insufficient information to adequately care for the emergency patients. In addition, most of the transferred patients had been transorted without prior information about transportation. Conclusion: Within the near future, a medical information center equipped with a computerized system should be operated to exchange medical data. As most general hospitals are operating the OCS(order communication system), EMR(electronic medical record), telemedicine, and PACS(picture-archiving communication system), medical information can be exchanged freely in real time if a code standard and HL7(Health Level 7) can be established.

      • 이동 애드 혹 네트워크에서 QoS를 지원하는 AODV 라우팅 프로토콜

        吳世德,趙榮泰,丁燦赫,金玄郁,李光培,姜景仁,朴京培,文泰洙,郭承郁,河載承 明知大學校 産業技術硏究所 2003 産業技術硏究所論文集 Vol.22 No.-

        Abstract - In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance victor routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end point is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average date reception rate. At that time, we used evaluation parameters such as node's mobility -stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.3% for 0 mobility-stop second case and 4.7% for 300 mobility-stop second case.

      • 토양으로부터 항세균성 물질을 생산하는 Streptomyces sp. 의 분리

        오현정,정완석,김세재,김창진,고영환 제주대학교 생명과학연구소 1999 제주생명과학연구 Vol.2 No.-

        제주도의 토양에서 분리된 방선균 307주를 대상으로, paper disc법과 시험관 희석 배양법을 사용하여 항세균성 물질을 생산하는 균주를 선별하였다. 약 3.3%에 상당하는 분리주들이 Escherichia coli 8749, Staphylococcus aureus 6538 그리고 Pseudomonas solanacearum 10692에 대해 항균효과를 나타냈고, 그 중에서 가장 높은 항균활성을 나타내는 BL93 균주를 최종선별하여 동정하였다. BL93 균주의 배양학적, 형태학적, 생리학적, 생화학적 그리고 화학분류학적 특성을 기준으로 볼 때 Streptomyces violaceus와 유사하였기에, Streptomyces sp. BL93으로 명명하였다. 이 균주가 생산하는 항세균성 물질은 butanol보다도 물에 더 잘 녹는 극성화합물로 chloroform이나 ethylacetate에는 거의 용해되지 않았다. 100℃에서 30분간 가열 처리해도 활성의 소실이 거의 없었고, pH 3∼9범위에서 안정하였다. 분리균주 BL93은 aspartocin을 생산하는 Streptomyces violaceus와 유사함으로, BL93이 생산하는 항세균성 물질의 동정 및 aspartocin과의 비교 검토가 선행되어야 할 것이다. Three hundred and seven isolates of Actinomycetes were isolated and purified from soil samples in Cheju Is. to screen antibacterial compounds. About 3.3% of the isolates showed antibacterial activity, and one of them, BL93, showed relatively higher antibacterial activity against Escherichia coli 8749, Staphylococcus aureus 6538 and Pseudomonas solanacearum 10692 by both paper disc method and tube dilution incubation method. The isolate BL93 was similar to Streptomyces violaceus based upon its cultural, morphological, physiological, biochemical and chemotaxanomic characteristics. It was designated as Streptomyces sp. BL93. The antibacterial substance produced by the isolate BL93 had higher affinity for water than butanol and was insoluble in chloroform or ethylacetate. Most of its antibacterial activity was retained even after heating at 100℃ for 30min and was stable at pH ranges 3 to 9. As the isolate BL93 was tentatively identified to be Streptomyces violaceus, the antibacterial substance preferentially need to be identified and compared with aspartocin, an antimicrobial compound produced by Streptomyces violaceus.

      • 섬유보강에 의한 고강도콘크리트의 내화성능 개선

        오상균,김세훈,남지현 동의대학교 산업기술개발연구소 2005 産業技術硏究誌 Vol.19 No.-

        Nowadays, it is a requirement to use high strength concrete for skyscrapers. Therefore safety research for high strength concrete is necessary. A fire outbreak in a reinforcement concrete structure looses the organism by the different contraction and expansion of hardened cement pastes and aggregate, and causes crack by thermal stress, leading to the deterioration of the durability. In this study, normal and high strength mortar were exposed to a high temperature environment. And than fundamental data for the character change of concrete heated highly were resented by measuring compressive strength of concrete with PP fiber and vinylon fiber, before and after heating. As the result, it is proven that adding PP fiber and vinylon fiber in high strength concrete for prevents deterioration of durability by fire.
