푸코-데리다의 광기 논쟁에 대한 ‘데리다적’ 독해 -「코기토와 광기의 역사」 다시 읽기-

김민호(Kim, Minho) 서울대학교 철학사상연구소 2021 철학사상 Vol.79 No.-

우리의 목적은 「코기토와 광기의 역사」를 데리다라는 사상가 ‘의’ 텍스트로서 읽음으로써 이 텍스트를 해석할 때 주로 푸코의 이후의 저작들에 조회하는 김은주의 논의를 일정하게 보충하는 데에 있다. 우리는 「코기토와 광기의 역사」에 선행하는 데리다의 두 저작, 즉 『발생의 문제』 및 『《기하학의 기원》에 대한 서설』에서 출발해서 이 논쟁에 개입한다. 이를 위해 우리는 『발생의 문제』 및 『서설』에서 푸코가 데리다를 비판하는 논점들이 앞질러 예고됨을 (2장), 그 함축에 입각하여 「코기토와 광기의 역사」가 감행하는 독해의 의의를 규명하면서 푸코의 데리다에 대한 비판이 데리다에게는 여전히 미진함을(3장), 마지막으로 데리다야말로 『성찰』을 하나의 사건으로 만들고 있음을(4장) 보인다. This article aims to complement Eunju Kim’s reading of “Cogito and the History of Madness,” oriented towards Foucault’s later works, by examining it in the light of Derrida’s early writings on Husserl’s thought, i.e. The Problem of Genesis in Husserl’s Philosophy and Introduction to Husserl’s Origin of Geometry. It argues that the basis of Foucault’s critique of Derrida’s interpretation of Meditations on First Philosophy, as reconstructed by Kim, is not far from that of Derrida’s own philosophy (II). From this viewpoint, Foucault’s critique is refuted in advance within the scope of “Cogito and the History of Madness” (III), which implies that, contrary to what Foucault and Kim believe, Derrida is the one who makes Descartes’ Meditations “an event worthy of its name” (IV).

접경지역 빛합계 지수의 지정학·지경학적 함의: 중국 단둥시를 사례로

김민호,지상현,정수열,이승철,Kim, Minho,Chi, Sang-Hyun,Chung, Su-Yeul,Lee, Sung-Cheol 한국경제지리학회 2017 한국경제지리학회지 Vol.20 No.3

본 연구는 DMSP 위성의 OLS 센서에서 촬영된 Stable Lights 영상자료로부터 랴오닝성과 단둥시의 빛합계 지수를 도출한 후 이 지표와 경제 수준 간 관계를 분석하였다. 랴오닝성의 빛합계 지수는 다른 성급 지역의 평균보다 높은 수준이었고, 지난 20여 년 동안 지속적인 증가 추세를 보였다. 실질 성장률과 1인당 평균 임금 등 이 지역의 경제 수준 향상을 지시하는 경제 지표 변화를 잘 반영한다고 볼 수 있다. 그러나 단둥시의 빛합계 지수는 다른 지급시 평균보다 낮은 수준이었는데, 이는 주요 경제 지표에 기초한 이 도시의 경제적 지위와 맥을 같이하는 것으로 보인다. 이전 시기에 비해 1998~2007년 사이 대북무역이 활성화된 단둥시 시할구의 빛합계 지수의 연간 증가율이 높아졌고, 비슷한 기간 동안 북중 교역액과 북한의 대중 수출액도 증가하는 패턴을 보였다. 이 기간 동안 햇볕정책의 영향으로 남 북한 간 긴장 관계가 완화되었던 것을 비추어볼 때, 빛합계 지수는 단둥시의 지정학 및 지경학의 특성을 설명할 수 있는 공간 대안 지표로 활용될 수 있을 것으로 기대된다. This research derived sum of light (SOL) for Liaoning and Dandong, China, from DMSP OLS satellite images acquired at nighttime during 1992 to 2012 and investigated its potential association with economic status. The SOLs of Liaoning were found to be continuously increasing and higher than those of averages for the other provinces across the time period. The temporal pattern of SOLs would be interpreted to well reflect the economic status of this region based on real growth rate and average wage per capita. Nevertheless, the SOLs of Dandong were lower than the average of the other prefecture-level cities, which indicated the economic status of this city in China. Meanwhile, the average annual growth rate of SOLs for Dandong turned out to be increase for 1998~2007, compared with the previous years, and temporal patterns in the trade amount between North Korea and China and the export amount of North Korea to China were similar to those of SOLs in the same time period. The political association between South and North Koreas was improved with 'Sunshine Policy' during 1997~2007. Taking it into account, SOL is expected to be valuable spatial proxy index that could explain the geopolitcal and geoeconomic aspects of Dandong.

본 연구에서는, 결과물의 우수함을 유지하면서도 기존 연구결과의 성능을 4-7배 향상시킨 실시간 GPU 등가면 볼륨 레이케스터를 제시한다. 이러한 성능 향상은 효율적인 빈공간 생략법과 분석적 그레디언트 계산법을 도입함으로써 가능하다. 빈공간 생략법은 스플라인 조각들의 BB-형식으로부터 만등어진 최소/최대값 옥트리에 기반하고 있고, 분석적 그레디언트 계산법은 보다 정확한 렌더링 결과를 제공할 뿐 아니라 더욱 빠른 계산이 가능하도록 한다. This paper presents a real-time GPU (Graphics Processing Unit) isosurface ray-caster that improves the performance by 4-7 folds from our previous method, while keeping the superior visual quality. Such an improvement is achieved by incorporating an efficient empty-space skipping scheme and an analytic normal computation. The empty-space skipping scheme is done by building an min/max octree computed from the BB(Bernslein-B$\acute{e}$zier)-form of spline pieces and the analytic normal Formula provides not only a nice visual quality but also an improved evaluation performance.

TCP Acknowledgement Compression for Fairness Among Uplink TCP Flows in IEEE 802.11n WLANs

김민호,박은찬,김웅섭,Kim, Minho,Park, Eun-Chan,Kim, Woongsup Institute of Control 2013 제어·로봇·시스템학회 논문지 Vol.19 No.7

This paper deals with the problem of unfairness among uplink TCP (Transmission Control Protocol) flows associated with frame aggregation employed in IEEE 802.11n WLANs (Wireless Local Area Networks). When multiple stations have uplink TCP flows and transmit TCP data packets to an AP (Access Point), the AP has to compete for channel access with stations for the transmission of TCP ACK (acknowledgement) packets to the stations. Due to this contention-based channel access, TCP ACKs tend to be accumulated in the AP's downlink buffer. We show that the frame aggregation in the MAC (Medium Access Control) layer increases TCP ACK losses in the AP and leads to the serious unfair operation of TCP congestion control. To resolve this problem, we propose the TAC (TCP ACK Compression) mechanism operating at the top of the AP's interface queue. By exploiting the properties of cumulative TCP ACK and frame aggregation, TAC serves only the representative TCP ACK without serving redundant TCP ACKs. Therefore, TAC reduces queue occupancy and prevents ACK losses due to buffer overflow, which significantly contributes to fairness among uplink TCP flows. Also, TAC enhances the channel efficiency by not transmitting unnecessary TCP ACKs. The simulation results show that TAC tightly assures fairness under various network conditions while increasing the aggregate throughput, compared to the existing schemes.

Many countries have been developing and operating an underwater surveillance system in order to protect their oceanic environment from infiltrating hostile marine forces which intend to lay mines, conduct reconnaissance and destroy friendly ships anchored at the harbor. One of the most efficient methods to detect unidentified submarine approaching harbor is sensing variation of magnetism of target by magnetic sensors. This measurement system has an advantage of high possibility of detection and low probability of false alarm, compared to acoustic sensors, although it has relatively decreased detection range. The contents of this paper mainly cover the analysis of possible effectiveness of magnetic sensors. First of all, environmental characteristics of surveillance area and magnetic information of simulated targets has been analyzed. Subsequently, a signal processing method of separating target from geomagnetic field and methods of estimating target location has been proposed.

본 연구에서는 PPG 신호 측정에서 포함되는 잡음들 중에서 동잡음을 제거하는 신호처리 방안을 제안한다. 측정되는 PPG 신호는 측정 환경 자체의 신호 잡음과 사용자의 동작변화로 발생하는 동잡음 등 여러 잡음이 같이 존재하므로 적절한 신호처리 방법이 요구된다. 본 논문에서는 사용자의 안정된 상태에서 실제 PPG 신호를 측정한 뒤, 이 기준 신호를 바탕으로 여러 채널에서 측정한 다중화된 PPG 신호를 이용하여 동잡음을 제거하는 신호 처리 방법을 제안한다. 본 논문의 실험에서는 두 개의 채널을 이용하여 PPG 신호를 측정하며, 각각 20%의 오류율을 가지는 신호를 본 논문에서 제안한 알고리즘으로 처리한 결과 9.56%로 오류율이 감소하였다. In this paper, we propose a methods to eliminate PPG sensor noise resulted from user motion during measurement. Measured PPG signals require approperiate signal processing methods since various types of noises such as a motion noise by user movement and signal noises occurred from the change of measuring environments. This paper suggests a signal processing method that eliminates motion noises by measuring several PPG channels that are based on the stable patterns of the practical users. The PPG signals are measured by the two channels in this experiment. When the individual error rates are 20%, the proposed algorithm reduces the errors to 9.56%.

RGB/HSV Method 를 이용한 Diesel-water emulsion 의 배기배출물 특성 연구

As the global warming and energy consumption increases, the diesel engine which had high thermal efficiency came into the spotlight again. However, the reduction of NOx and PM are still to be solved. Therefore, this study was applied to the diesel-water emulsified fuel (DE), which can simultaneously reduce NOx and PM, and the possibility of its application to conventional diesel engines was evaluated from the fundamental characteristics of diesel-water emulsified fuel. First of all, to examine the basic characteristics of DE depending on the type, content, and manufacturing time of surfactants, five surfactants were selected and a certain manufacturing ratio and time was given as a boundary condition. The produced DEs were evaluated in terms of water droplet size inside of the DE and stability. Before the four types of fuel in total (DE10/20 per two surfactants) were applied to diesel engines, an experiment was conducted as the preliminary step to examine the fuel characteristics such as injection quantity, injection rate, and spray behavior in the diesel fuel supply system. The DEs were applied to actual diesel engines and their combustion, emission, and fuel consumption characteristics were compared with those of diesel. In the experiment, the injection timing maintained the same with diesel. It was observed that all DEs involved the increase of injection quantity due to the low calorific value. In the low-load condition, ignition delay occurred, and as the load increased, ignition was advanced because of low ambient temperature due to the evaporative latent heat of water. Coefficient of variation (COV) of all DEs was stable as low as 2.0% and the combustion duration was shorter than that of diesel. NOx and PM generation rates of DEs were far lower than those of diesel, and so was THC probably because of the favorable function of the micro-explosion and evaporative latent heat. The value of CO, however, was higher because of the low CO oxidation rate. In the combustion visualization experiment where the macroscopic observation and digital image analysis were implemented, the micro-explosion phenomenon was observed. The attempt to predict PM generation rate failed due to the flame color, but the result of predicting NOx generation rate was persuasive enough to grasp the tendency. This study focuses on the use of diesel-water emulsified (DE) fuel to reduce NOx and PM emissions and evaluates its application to conventional diesel engines based on the fundamental characteristics of DE fuel. DE fuels were applied to actual diesel engines, and their combustion, emission, and fuel consumption characteristics were compared with those of diesel fuel. The injection time was the same in all experiments. The coefficient of variation (COV) of all DE fuels was stable at a value as low as 2.0%, and the combustion duration was shorter than that of diesel fuel. The NOx and PM generation rates of DE fuels were considerably lower than those of diesel fuel because of the beneficial effects of the micro-explosion and evaporative latent heat.
