Halothane 마취중 Propranolol 이 Gallamine 의 속맥에 미치는 영향

김순태,임웅모 대한마취과학회 1978 Korean Journal of Anesthesiology Vol.11 No.4

That gallamine causes tachycardia during general anesthesia is well known, but the efficacy of its anticholinergic action or an adrenergic beta blocking action remains to be determined. Twelve patients were subjocted to this study, in which under halothane anesthesia small doses of propranolol. an adrenergic beta-blocker, was administered. In all cases bradycardia resulted and the greatest decrease was noted five minutes after intravenous injection of propranolol(0. 5 1. 0mg). At the height of bradycardia, gallamine 80 mg was administered intravenously. In all cases gallamine produced a significant increase of heart rate over the level before the injection of propranolol, but not so much as without propranolol pretreatment. But fifth minute values after propranolol expressed as 100 per cent, (per cent change in heart rate after propranolol followed by gallamine,) and after gallamine were similsr effectively. This study suggested that gallamine-induced tachycardia is modified, but its anticholinergic aetion is not impaired by propranolol, and that gallamine-induced tachycardia is caused by anticholiaergic action of gallamine.

원격치료는 침, 한약, 양약의 투여, 양방의 수술 등을 통하여 치료하는 기존의 방법과는 달리 환자를 직접적으로 몸에 손을 대지 않으면서 가까운 거리 또는 먼 거리에서 심지어는 지구 반대편에서도 상대방의 영체를 데려와서 인체를 투시하여 환자의 아픈 부위를 치료 기운으로 치료하는 방법이다. 인간의 육체는 크게 정(情), 기(氣), 신(神)으로 이루어져 있다. 다시 말하면 흔히 우리들이 보고 만지고 느껴지는 인체 해부학적연 육체와 그 육체 안에 내재되어 있는 기(氣)로 이루어져 있는 기체(氣體, 마음) 및 영혼(靈魂)으로 이루어진 신(神)이 있는데 이 세 가지 복합 유기적으로 작용하면서 생명을 유지하고 있다. 원격치료는 정(情), 기(氣), 신(神) 가운데 기(氣)와 신(神) 을 치료하여 육체가 치료되게 하는 방법이라 하겠다.

Emission impacts of nonpublic anthracite burning facilities in Dangjin, Pohang, and Gwangyang before and after vertical reallocation of low-level emissions to elevated emissions on PM2.5 concentration were estimated with Community Multiscale Air Quality Modeling System (CMAQ) model simulations during the Korea-US Air Quality Study 2016. When CAPSS 2016, anthropogenic emissions inventory in South Korea, was examined, the low-level emissions explained more than 96% of the total primary PM2.5 and SO2 emissions, possibly due to uncontrolled emission factors applied during the emission estimate. Consequently, CMAQ simulations including the low-level emissions over-predicted PM2.5 and SO2 concentrations by up to 7.5 times and 9.2 times respectively of the observed concentrations at adjacent air quality monitoring stations. When the low-level emissions were vertically reallocated into elevated ones emitted from large stacks, their impacts on surface PM2.5 concentrations in surrounding areas decreased by up to 66~82%. In addition, the vertical reallocation lowered modeled PM2.5 concentrations by one-fifth, making them more comparable to the surface observations. The simulated SO2 concentrations at airborne measurement altitudes (300~500 m) increased only by a few ppb which is a fairly small change compared to the surface-level SO2 change after the vertical reallocation (i.e., a 28.5 ppb decrease of simulated SO2 concentrations in Gwangyang). It implies that not only the emission rates of air pollutants but also their precise release information should be prepared together prior to developing emission reduction plans and evaluating the effects on air pollution alleviation. Moreover, emission reduction plans should be evaluated in terms of ambient concentration rather than emission itself.

KLIS 아키텍처 개선에 관한 연구 : 미들웨어 성능개선방안을 중심으로

김순태 국토지리학회 2009 국토지리학회지 Vol.43 No.1

The current KLIS has derived from the integration between PBLIS and LMIS based on the database and functions in the past. Besides it is operating with many problems of architecture due to the absence of delicate consideration and improvements for existing architecture. To solve the architecture problems, this paper studied applicable improvement way to the KLIS system within minimum changes of the architecture in many of the early studies based on the OpenGIS with consideration of the current operating system in KLIS. The applied detail improvement way proposed three main apply methods such as improvement of the components, improvement of the distributed object environment and improvement of using cache techniques. 현재의 한국토지정보시스템(KLIS)은 과거 필지중심토지정보시스템(PBLIS)과 토지관리정보체계(LMIS)를 DB 및 기능을 중심으로 통합한 시스템으로, 기존 아키텍처에 대한 세심한 고찰 및 개선사항 없이 과거의 미들웨어를 그대로 유지하는 형태로 통합됨으로 인하여, 아키텍처상의 여러 문제점이 내포된 상태로 운영되고 있는 실정이다. 따라서 이러한 아키텍처상의 문제점을 해결하기 위한 방법으로, 기존의 OpenGIS를 기반으로 한 많은 연구들 중 현재의 KLIS가 운영 중인 시스템임을 고려하여, 아키텍처를 크게 흔들지 않는 범위 내에서 KLIS에 적용가능한 부분을 중심으로 개선방안을 모색하였다. 특히 컴포넌트 개선, 분산객체 환경 개선, 캐슁 기법을 활용한 개선 등의 3가지 방법을 중심으로 그 세부 적용방안을 제시하였다.

지적정보의 통합관리체계 구현에 관한 연구

김순태 한국지적학회 2010 한국지적학회지 Vol.26 No.2

In 2008 the property-related business was transferred from Ministry of Government Administration and Home Affairs(former name) to the Ministry of Land, Transport and Maritime Affairs. As a result, it has various formation in terms of information management by property business integration policy of Korean government without enough preparation. In addition, the various information management system induce problems which are discordance between map and terrier and degradation of system performance with inefficient technical advance in application program to different institution. Besides, this situation is going to be obstacle of cadastral suitability guarantee that could be used in based data that is important in property rights. Thus in this study, I am going to analyze the problem of separated management in map and terrier and make logical basement on the cadastral business integration system by suggesting an reasonable alternative in system infrastructure, data discordance, maintenance, and architecture. 지적업무가 2008년 정부의 부동산업무 통합일원화 방침에 의하여 충분한 사전준비 없이 국토해양부로 이관됨으로써 동일한 지적업무임에도 불구하고 그 정보의 관리측면에서 다원화된 형태를 지니게 되였다. 결과적으로, 이러한 다원화된 관리구조는 도면과 대장의 정보가 상호 불일치되는 문제와 함께 서로 다른 기관에 의한 비효율적인 응용프로그램 유지보수로 인하여 시스템 성능을 저하시키는 문제점도 야기하게 되었다. 뿐만 아니라 이러한 상황은 국민의 재산권 행사에 중요한 근거자료로 활용되는 지적정보의 정합성 확보에도 걸림돌이 되고 있다. 따라서 본 연구에서는 도면과 대장의 분리 운영에 따른 문제점들을 분석하고 시스템 인프라, 자료 불일치, 유지보수, 아키텍처 등 4가지 측면에서의 합리적 대안을 제시함으로써 지적정보 통합체계 구축의 논리적 토대와 실천적 대안을 마련하고자 하였다.

INTEGRATED FAULT DETECTION AND DIAGNOSIS SYSTEM FOR LONGITUDINAL CONTROL OF AN AUTONOMOUS ALL-TERRAIN VEHICLE (ATV)

김순태,송호인,송봉섭 한국자동차공학회 2009 International journal of automotive technology Vol.10 No.4

This paper presents a fault detection and diagnosis (FDD) method to enhance the reliability and safety for longitudinal control of an autonomous all-terrain vehicle (ATV). An integrated approach using decentralized and centralized FDD is proposed to optimize the tradeoff between sensitivity and robustness. While the decentralized approach is suitable for detecting faults in actuators and sensors directly connected to a single processor, it is sensitive to noises and disturbances and thus may result in false alarms. On the other hand, the centralized approach is based on information communicated between multiple processors, and it detects and diagnoses faults through analyzing concurrent computations of multiple hardware modules. However, its performance is still limited to isolating faults specifically in terms of components in the single hardware. To incorporate the advantages of both FDD approaches, a two-layered structure integrating both decentralized and centralized FDD is proposed and allows us to perform more robust fault detection as well as more detailed fault isolation. Finally, the proposed method is validated experimentally via field tests of an ATV.

Effects of Copper and Sulfur Additions on Machinability Behavior of High Performance Austenitic Stainless Steel

김순태,박용수 대한금속·재료학회 2009 METALS AND MATERIALS International Vol.15 No.2

Flank wear, cutting force, the number and area of sulfides, and shear strain rate were measured to elucidate the synergistic effects of Cu and S additions on machinability of high-performance austenitic stainless steels with a basic composition of Fe-18 %Cr-21 %Ni-3.2 %Mo-1.6 %W-0.2 %N. As Cu and S content increased, flank wear and cutting force decreased. While Cu and S content increased, shear strain rate and shear angle increased. The tool life for an alloy with 3.1 %Cu + 0.091 %S was about four times longer than that of an alloy with 0.06%Cu + 0.005 %S due to high shear strain rate generated by Cu addition, lubricating films of ductile (Mn, Cr)S sulfides adhering to tool surface and low cutting force resulting from thinly and lengthily continuous sulfides formed in chips during machining.
