목적 : 병원 감염과 지역 감염의 원인균으로서의 중요성이 증가되고 있는 MRSA와 MRCNS의 메티실린 내성 관련 유전자에 대해 분자역학적인 조사를 시행하고 mec 조절유전자의 다양성을 분석하여 분자유전학적 연구와 감염 관리에 기본적 자료를 제공하고자 연구를 시행하였다. 방법 : 본 연구에서는 국내 동일 대학병원에서 분리된 mecA 양성 MRSA 78균주와 MRCNS 36균주를 대상으로 항균제 감수성 검사와 중합효소연쇄반응을 시행하여 표현형과 유전형의 분포를 알아보고 내성 정도와 유전형의 상관성을 분석하였다. 결론 : 최소억제농도를 측정하여 oxacillin 감수성 양상을 알아본 결과 총 90개의 MRSA 임상검체 중 3균주에서 감수성을 보였고, MRCNS 36균주는 모두 내성을 보였으며, 고도 내성을 보이는 균주일수록 다제내성을 보이고 있었다. 중합효소연쇄반응으로 mecA 유전자 유무를 분석하여 mecA 양성을 보인 MRSA 78균주와 MSCNS 36균주 만을 대상으로 mec 조절유전자에 대한 중합효소연쇄반응을 시행하여 유전형의 분포를 조사하였다. 그 결과 MRSA와 MRCNS 모두에서 mecA-Pr-mecA-mecR1-mecI형, mecA-Pr-mecA-mecR1형과 mecA-Pr-mecA-mecR-1의 5′말단형의 3가지 유전형이 공통적으로 관찰되었는데, 이외에 MRSA에서는 mecA-mecR1형, mecA-mecR1의 5′말단형이, MRCNS에서는 mecA-Pr-mecA형과 mecA형이 추가로 분리되었다. 유전형의 분포를 연도별로 분석한 결과 연도별로 우세한 유전형이 서로 다른 것을 알 수 있었다. 유전형과 내성 정도의 상관성을 분석한 결과, mecA-Pr-mecA-mecR1을 보유한 MRSA의 경우 mecA 억제유전자로 생각되는 mecI 유전자 유무에 관계없이 모두 고도 내성을 나타내어 mecI의 유무는 내성 정도와는 일정한 관련이 없었으나, MRSA와 MRCNS 모두에서 mecI와 동시에 mecR1의 3′말단이 결혼된 유전형이 저도 및 중등도 내성을 보이는 균주에서 유의하게 많이 관찰되어 mecI가 결손된 균주에서는 mecR1의 3′말단부위의 유무가 내성 정도의 결정에 중요한 역할을 할 것으로 생각하였다. 결론 : 국내에서 분리되는 메티실린 내성 포도구균의 유전형의 분포가 국외 분리주와 차이를 보이는 것으로 관찰되었다. 또한 기존의 보고와는 달리 메티실린 내성 정도와 유전형 사이에 유의한 연관성이 있는 것으로 관찰되어 mec조절유전자가 내성 발현 뿐만 아니라 내성 정도의 결정에 중요한 역할을 하는 것으로 관찰되었다. MRSA가 중요한 감염균임에도 불구하고 아직까지 MRSA의 내성기전에 대해 확실하게 규명되지 않아 치료가 더욱 어려워지고 있는 실정이므로 이에 대한 더욱 종합적인 연구와 동시에 발생과 확산을 막기 위한 노력이 필요할 것으로 생각된다. Background : High prevalence of methicillin resistance has been noticed in staphylococci which also have been recognized as important nosocomial and multi-drug resistant pathogens. In this study, we investigated the distribution of mec regulator genes and the presence of the mutation in mecIgene to reveal the resistance mechanism at molecular level. Methods : The isolates included 90 clinical isolates of MRSA, 36 MRCNS of which methicillin resistance were determined by disk diffusion test and isolated in a single hospital during 1996-1999. We performed microdilution MIC test for oxacillin resistance and Kirby-Bauer test for other antibiotics. Genotypes of mecA positive (determined by PCR) isolates (78 MRSA, 36 MRCNS) were investigated by PCR amplification of mec regulator genes such as 3' end and 5' end of mecR1. mecI, and Pr-mecA. Results : In MIC assay, all MRSA strains except 3 strains and all MRCNS strains showed oxacillin resistance. The level of resistance correlated to the multi-drug resistance. Seven genotypes were observed in mecA positive MRSA and MRCNS. Differences of predominant genotypes among years isolated and among species were observed. Deletions of the 3' end of mecR1 and the mecI were more frequently observed in the low- and borderline-level resistant MRSA and MRCNS (P(0.05). So the important role of 3' end of mecRI in determining resistance level was suggested. Conclusion : This study demonstrated that genomic distribution of methicillin-resistant staphylococci isolated in Korea was different from that of strains isolated in other countries. And important role of mec regulator genes for expression of methicillin resistance was suggested.

As modern people's interest in health grows, wearable healthcare-related technologies that can collect biometric information and receive health-related services regardless of time and place are developing. This paper proposes the healthcare system based on voice recognition function. Unlike conventional wearable healthcare systems, the proposed system provides real-time telemedicine and diagnosis and the direct connection with doctors is possible through it. And almost all functions of the application in it are operated with voice commands to lower user access barriers. Because it deals with personal information including medical information, encryption algorithms have been applied between all data movements. Finally, the healthcare system proposed in this paper is expected to increase convenience in health care and reduce the medical gap.

This study tried to reconsider the connecting order of the Twelve Main Meridians thought to be reasonable until now, on the commonsensical level of "the principles of reason" with the motive of taking off the bad habit of "the indolence" that we had made academic researches without the question of "why". In this study, the model was suggested for the purpose of being explained in the sides of the kinetics and the structure. And this study tried to obtain the prehension of the reality through the reason of "one-two-One". This study tried to reason about the most suitable structure of the connecting order with several theory on the assumption that we only knew the distribution of the Twelve Main Meridians, with the bearings and mean of the connecting in the Twelve Main Meridians excluded. I reflected present conditions that the reality of the Meridians wasn't made clear and proposed to design a model and made every effort to investigate the model vastly from the structural and kinetic relations of the model to the physiology and circulation of the Qi(vital energy) of human vital pheonomena. Chapter 3 provides the theory needed to understand the connecting order of the Twelve Main Meridians, as follows : "Pyo Bon Jung Qi"(標本中氣), exterior and interior of the body(the structure of "Yeo Hwan Moo Dan"(如環無端) through these theories), three rings made by "Kyo Sang Hap"(交相合), and "Yuk Hap"(六合) of the Twelve Main Meridians, "Jang Boo Sang Tong"(臟腑相通). In chapter 4, the connecting order of the Twelve Main Meridians is reconsidered from the sides of the Five Elements. From the theoretical investigation, I could reach to the object of this study about the connecting order of the Twelve Main Meridians and the theoretical "reasonability" : that is, the present connecting order of the Twelve Main Meridians is very reasonable.

The purpose of this study is to investigate the variation of pore size distribution of the coal-based extruded activated carbon. The extruded activated carbon was prepared by extruding the mixture of coal powder and coal tar. Pore size distribution of the extruded activated carbon was compared with that of the extruded coal and the extruded char. Also it was compared with that of the crushed activated carbon, raw coal and char. The extruded coal had coarser surface than that of raw coal. Macropores of the extruded coal were funned near 10,000Å in diameter during carbonization process and steam penetrated easily between particles and were growing between 3,000Å and 20,000Å in diameter during activation process.

Interventional neuroradiologic procedure represents treatment of central nervous system disease by endovascular access for the purpose of delivering therapeutic agents, including both drugs and devices. For optimal anesthetic management, anesthesiologists should be familial with specific radiological procedures and their potential complications. The role of the anaesthetist in INR consists in providing patient comfort by analgesia and sedation, adequate monitoring, maintenance of vital functions and(if required) the management of systemic heparinisation. The patient's underlying condition, the duration and the kind of intervention have to be considered to decide on the anaesthetic management. Knowledge of the risks and hazards of the different procedures and close collaboration with the neuroradiologist form the basis for appropriate management in case of a potentially fatal ischemic or haemorrhagic complication. For prompt control of airway, respiration and blood pressure in these emergencies experienced anaesthesia staff is required.

반도체 레이저의 이득 스위칭에 의한 초단 펄스 발생에 대해 체계적으로 연구하였다. 즉, 동작 파라메터인 DC 바이어스 및 RF 정현파 전력에 따른 초단 이득 스위칭된 출력 펄스의 특성을 조사하였다. 최적의 펄스는 문턱 전류 부근의 DC 바이어스에서 얻어졌으며, RF 전력이 클수록 이 최적의 DC 바이어스는 감소하였다. 출력 펄스 폭은 RF 전력이 증가할수록 DC 바이어스의 변화에 덜 민감하게 나타났다. We study systematically on short pulse generation from a semiconductor laser by gain-switching. We examine the dependence of gain-switched pulse characteristics on the operating parameters, such as DC bias and RF power. The optimum short pulses are obtained around threshold DC bias. As the RF power increases, The DC bias to show shorter pulse width decreases slightly and the pulse width becomes less sensitive to the variations of the DC bias.
