본 논문의 주요 목적은 한국의 의학 교육 환경에서 수동성의 특유한 모습과 속성을 드러내어 설명하고, 레비나스의 수동적-수동성 개념의 재해석에 의거하여 한국 의료 환경을 개선하기 위한 제언을 제시하는 것이다. 만일 이 목적이 충분히 이루어진다면, 다음으로 생물학적 종-특정적 감각과 감정에 기초하여 인간 행동을 설명할 수 있는 가능성의 토대를 찾아보는 시도를 할 것이다. 동아시아의 의학교육은 일반적으로 제국주의에 따른 식민시대로부터 시작되었다. 그러한 이유로 동아시아의 여러 나라들은 의학교육에 있어 식민지 문화 수용 방식에 따라 서로 다른 양태를 보인다. 하지만 동아시아의 나라들은 제국주의의 식민적 의학교육을 별다른 저항 없이 수용하였다. 한국의 의료문화와 의학교육의 특징은 이러한 역사적 맥락 속에서 이해될 수 있을 것이다. 레비나스에 의해 발견된 수동성과 타자성에 대한 새로운 의미는 한국의료문화에서 문제가 되는 수동성을 새롭게 이해할 수 있는 윤리적 견해를 제시한다. 한국 의료문화의 수동성은 레비나스의 승화된 수동성에 의해 개선될 수 있다. 한국 의료 환경에 재해석된 수동성 개념을 적용하는 것의 의의는 레비나스의 이론과 전통적 유가사상, 양육방식의 관계를 분석하는 가운데에서 발견될 것이다. 한국 의료 환경에 적용하려는 레비나스에 의거한 새로운 수동적-수동성 개념이 그럴듯한 것이라면, 우리는 다음으로 실제 의료환경에 적용할 수 있는 개념적이고 실천적인 이론을 모색해보아야 한다. 생물학적 그리고 종-특정적 감각적 토대에 기초하는 공감의 윤리는 인간의 감각, 지각 그리고 감정에 의거하여 인간 행동을 설명하기 때문에 인간 행위의 현상을 잘 설명할 수 있는 이점이 있다. 만일 이러한 시도가 그럴듯한 것이 라면, 그 시도는 윤리적 수동성과 타자성의 새로운 도덕적 토대를 제시하는 의미있는 도전이 될 것이다. The main purpose of this paper is to explain and reveal the peculiar aspect and property of passivity in Korean environment for medical education, and to make a proposal for improving Korean medical culture in virtue of reinterpretation of the concept of Levinas`` passive-passivity. And if the purpose is fully fulfilled, then it will try to seek for the possibility of explaining human behavior based on the biological species-specific sense and emotion. Medical education in East Asian countries was originated from colonialism. Therefore, medical education in each East Asian country has different aspects through ways that depend on each colonial acculturation agency. East Asian nations succumbed to colonialism without much resistance. In this historical context, we can grasp the trait of Korean medical culture and education. A recent discovery of the new meaning of passivity and heteronomy by Levinas opened a new realm of ethical views, which support noble refinement of the problematic passivity in Korean medical culture. The problematic medical culture of Korea could be enhanced in terms of a conception of "passivity" whose concept was sublimated by Levinas. The aptness of this direction of improvement will be shown in a discourse of relationship between the thoughts of Levinas and traditional Confucianism. And if the new concept of passive-passivity (passivity for other-ness) in terms of Levinas is reasonable, we must seek the conceptual and practical theory which is applied to the real Korean medical educational environment. The sympathetic ethical theory based on biological and species-specific sensational ground have a merit of explaining the phenomenon of human action since that approach well accounts for human behaviors in terms of sense, perception and emotion. If it is plausible, then this attempt may be a meaningful challenge which tries to offer a new moral foundation of ethical passivity and heteronomy.

使動과 受動의 相關性에 基盤을 둔 現代中國語 結果補語構造와 可能補語構造의 統辭的 變形 關係 硏究

金玧廷 한국중국언어문화연구회 2008 한중언어문화연구 Vol.- No.17

The purpose of this paper is to explore the structural connection between Complement of Result (CR) and Potential-Marking Complement (PMC) in Modern Chinese based on the semantic relevance between causativity and passivity. This research found that the only difference was the addition of the mark de between PMC and CR. Also, this paper will suggest that the semantic relevance between causativity and passivity is a clue to understanding the close structural connection between these two structures. In particular, this paper includes a cross-linguistic analysis of the semantic relevance between causativity and passivity, resulting in the phenomenon that these two categories are expressed as the same form. It has already been suggested that there is causativity in CR and that there is passivity in PMC, so it is the hope of this paper that the result that causativity and passivity are related both semantically and syntactically will clarify the structural connection between CR and PMC. This paper is formed by the following discussions: (1) to examine the common semantic feature between causativity and passivity; (2) to analyze the causativity of CR and the passivity of PMC; (3) to examine the functional division made by the relevance between CR and PMC by comparative analysis of these two complement constructions.

「おぼゆ」「思ほゆ」「思はる」の用法

유춘희(Yu, Chun Hui) 국제언어문학회 2016 國際言語文學 Vol.- No.35

A classical verb 「oboyu」in Japanese is a word from changing of「omohoy u」, which is a verb 「omou」connected with a auxiliary verb 「yu」, and a previous form of 「oboyu」.「omoharu」, which was formed from connecting with 「ru」that has the previous form of auxiliary verb 「yu」, has similarity with 「omohoyu」in the character and meaning. In other words,「oboyu」 「omohoyu」「omoharu」can be postulated as words used within the same boundary in their meaning and usage.「oboyu」「omohoyu」「omoharu」are intensively appeared in mainly 『genjimonogatari』among literary works during Heian period of Japan. By the way, the cases that spontaneity is translated as possibility or passivity are found in the process of interpreting scenes.It can be postulated that「omohoyu」「omoharu」have the same use of spontaneity, possibility, and passivity if「oboyu」has the use of spontaneity, possibility, and passivity. Based on these points, each usage of 「omohoyu」「omoharu」 「oboyu」was examined. The following result was found by comparing them. 「oboyu」and 「omohoyu」have little difference for the usage in 『genjimonogatri』but they are in confrontation with each other over spontaneity and passivity. That is, 「omoharu」is used as passivity that is influenced by the movement of characters while 「oboyu」is used as spontaneity that a certain situation or event is naturally realized for its characters. To sum up,「oboyu」 (「omohoyu」) and「omoharu」have a contrasting relation of spontaneity and passivity. 「omoharu」has only role of passivity. That is, it can be interpreted that 「oboyu」「omohoyu」「omoharu」have a complementary relationship and they share their roles.

Passivity-Based Design for LCL-Filtered Grid-Connected Inverters with Inverter Current Control and Capacitor-Current Active Damping

Fan Zeyang,Yi Hong,Xu Jian,Xie Kun 대한전기학회 2024 Journal of Electrical Engineering & Technology Vol.19 No.3

Passivity-based design gains much popularity in grid-connected inverters (GCIs) since it enables system stability regardless of the uncertain grid impedance. This paper devotes to a systematic passivity-based design guidance for the LCL-fltered GCI with inverter current control and capacitor-current active damping. It is found that the passivity can be guaranteed with an optimal damping gain of the capacitor-current active damping, but it sufers from both the flter parameter drift and the lagging phase of the current regulator, especially at the one-sixth sampling frequency. To address this issue, a phase-lead compensation is introduced in series with the current regulator, which helps to enhance the full-band passivity and high robustness against the aforementioned challenge. Experiments are conducted to confrm the theoretical expectation.

Passive-based Bilateral Controller Design under Varying Time Delay

고영(Ying Gu),정길도(Kil To Chong) 대한전기학회 2009 정보 및 제어 심포지엄 논문집 Vol.2009 No.5

Bilateral teleoperation systems, connected to computer networks such as Internet have to deal with the time delay varying depending on factors such as congestion, bandwidth or distance. And the entire system is easy to become unstable due to irregular time delay. Passivity concept has been using as a framework to solve the stability problem in bilateral control of teleoperation. Acontrol scheme for teleoperation systems with varying time delay is proposed based on a passivity concept is proposed in this paper. One approach makinguse of the characteristic impedagces is proposed to achieve a passive control. Since passive control does not mean that the system performance will be acceptable, another transmission scheme which focuses on both the passive feature and the acceptable performance is configured for varying time delay in this paper. The tracking performance has been proved through the computer simulation for varying time delay bilateral teleoperation system using Matlab Simulink.

Robust Tracking of Robot Manipulators via Momentum-based Disturbance Observer and Passivity-based Controller

하원석,백주훈 제어·로봇·시스템학회 2019 International Journal of Control, Automation, and Vol.17 No.4

The passivity-based controller is one of most widely-used controllers for robot manipulators. Since itstrongly exploits the system properties, it does not produce unnecessarily large control effort and has inherent robustnessagainst plant uncertainty and disturbance. This paper presents an inner-loop controller which can enhancethe robustness of the passivity-based tracking controllers. The inner-loop controller developed in this paper robustlyestimates the lumped disturbance, which is defined by the effect of plant uncertainty and external disturbance, andgenerates a compensating signal so that the closed-loop system consisting of the uncertain robot, disturbance observer,and passivity-based controller behaves like the nominal closed-loop system composed of the nominal modelof the robot and the passivity-based controller. It is seen that the tracking error can be made arbitrarily smallby choosing the controller parameters appropriately and the performance of the proposed controller is validatedthrough numerical simulations.

Hybrid passivity‑based control for stability and robustness enhancement in DC microgrids with constant power loads

Qihong Xian,Yubin Wang,Fan Wang,Ruixin Li,Song Wang 전력전자학회 2023 JOURNAL OF POWER ELECTRONICS Vol.23 No.2

In a DC microgrid, the negative damping characteristics of a constant power load can deteriorate the stability of the whole system. To improve the robustness and stability of the DC microgrid, a hybrid passivity-based control of damping injection is presented in this paper. The stability of the closed-loop system is ensured by the energy dissipation property of the passivity-based control. A proportional-integral controller is integrated with the passivity-based controller to form a hybrid passivity-based control to improve control robustness. A small-signal model of a DC power system with constant power load is derived in detail, and the stability of the system is analyzed with the Lyapunov eigenvalue method. The proposed hybrid passivity-based control provides the system with a faster recovery and a larger power boundary when compared with the typical voltage-current dual-loop control. First, the proposed control is verified by simulation of the DC power system based on MATLAB/Simulink, and the feasibility and superiority of the proposed control are further verified by hardware-in-loop (HIL) experiments based on real-time laboratory (RT-Lab) and a TI DSP TMS320 F28335.

Time-Domain Adaptive Control Scheme for a New Passivity Condition Including the Human Arm Impedance

Hyun Soo Woo,Doo Yong Lee 제어로봇시스템학회 2011 제어로봇시스템학회 국제학술대회 논문집 Vol.2011 No.10

The new passivity condition including the human arm impedance shows that the achievable maximum stiffness at each sampling period depends on the local minimum viscosity of the human arm during the sampling period. Based on the analytical results and the characteristics of the human arm, a new control scheme is proposed to improve the performance of the haptic system, when the human arm impedance varies largely. We present a method to predict the local minimum of the human arm viscosity at every sampling period and design an adaptive virtual coupling that maximizes the performance of the system while guaranteeing the passivity of the system. The newly defined Passivity Margin Tracker (PMT) tracks how much more conservative the haptic system is than the ideal mass-spring system in the aspect of the passivity. These results are verified through experiments to affirm that the proposed method is shown to usefully improve the performance of a haptic system if the human arm viscosity is initially calibrated.

MCV 수동화를 기반으로 한 굴삭기 자동정지 제어

김광민(Kwangmin Kim),김민지(Minji Kim),김동목(Dongmok Kim),이동준(Dongjun Lee) 대한기계학회 2016 대한기계학회 춘추학술대회 Vol.2016 No.12

We propose a passivity-based control framework for the excavator with main control valve (MCV). We first derive mathematical model of a 4-way valve, then develop a passivity-based control rule using spool actuation forces as control inputs. The passivity-based control is done in two steps: 1) MCV passifying control and 2) spool actuation control. First, the flow rate of each valve in MCV is decomposed into active flow source and a passive dissipation, and valve passifying control is presented based on this structure. Second, we present a spool actuation input to control the spool position to the desired value. In addition, we compensate the self-weight in order to make the passivity of the excavator less conservative. Finally, we propose a passivity-based auto-stop function of excavator when it collides with an underground obstacle.
