감각적 확실성과 지표적 표현의 문제

김주용 ( Kim¸ Ju Yong ) 한국헤겔학회 2020 헤겔연구 Vol.0 No.48

「감각적 확실성」을 중심으로 헤겔로부터 지표사 이론을 읽어내려는 시도에는 최소 세 가지 해석이 존재한다. 첫째로 개별자 지시 불가능성 독법은 헤겔이 개별자를 언어적으로 인식할 가능성을 원천적으로 배제했다고 이해한다. 둘째로 지시 이론적 독법은 앞의 입장을 비판하면서, 언어가 대상을 지시한다는 고전적인 지시 이론적 생각을 헤겔로부터 읽어낸다. 셋째로 브랜덤의 대용어 이론 독법은 헤겔에서 개별자에 대한 인식 가능성을 옹호하면서도 고전 지시 이론적 발상과는 다른 설명 방식을 제시한다. 본고에서는 앞의 두 가지 독법을 비판하고 세 번째 독법이 해석상으로 및 철학적으로 가장 적합하다는 점을 논증한다. 첫 번째 해석은 헤겔로부터 일종의 회의론을 이끌어내려고 한다. 그러나 헤겔을 회의론자로 읽어내려는 그러한 시도는 기껏해야 아주 제한적인 의미에서만 성공적일 수 있으며, 그렇게 구성된 회의론은 헤겔의 입장을 논박하기에는 지나치게 사소하다. 두 번째 해석은 첫 번째 독법의 오류를 범하지 않는다는 점에서 보다 적합한 해석이지만, 이 독법 또한 여전히 헤겔이 거부했던 주체와 객체, 정신과 세계사이의 이원론을 도입한다는 점에서 부적절하다. 세 번째 해석은 첫째와 둘째 독법에서 각각 발생하는 회의론과 이원론의 문제를 회피하면서도 개별자에 관한 지표적 지식에 대해 적절한 설명을 제시하고 있다는 점에서 앞의 두 가지 독법에 비해 강점을 지닌다고 할 수 있다. There are at least three interpretations that attempt to read from the Sense-Certainty Chapter a Hegelian theory of indexicals. First, the Impossibility of Singular Reference Reading understands Hegel as excluding in principle the possibility of any linguistic cognition of individuals. Second, the Theory of Reference Reading criticizes the first reading and interprets from Hegel the classical idea of direct reference theory. Third, Brandom’s Anaphoric Theory Reading suggests an alternative explanation while still defending the possibility of knowledge of individuals in Hegel. I criticize the first two readings and argue that the third is the most exegetically and philosophically adequate interpretation. The first interpretation attempts to ascribe to Hegel a sort of skepticism, but this can be at most in a very restricted sense successful and the skepticism constructed in such a way is too trivial to refute Hegel’s position. The second reading is more adequate in that it does not fall into the error that the first one committed, but is still flawed because it introduces a subject-object or mind-world dualism that Hegel denies. The third reading has great advantages compared to the first two readings in terms that it provides a suitable account of indexical knowledge on individuals while avoiding skepticism and dualism which arise in the former readings.

Driving Control Algorithm for Maneuverability, Lateral Stability, and Rollover Prevention of 4WD Electric Vehicles With Independently Driven Front and Rear Wheels

Juyong Kang,Jinho Yoo,Kyongsu Yi IEEE 2011 IEEE Transactions on Vehicular Technology VT Vol.60 No.7

<P>This paper describes a driving control algorithm for four-wheel-drive (4WD) electric vehicles equipped with two motors at front and rear driving shafts to improve vehicle maneuverability, lateral stability, and rollover prevention. The driving control algorithm consists of the following three parts: 1) a supervisory controller that determines the control mode, the admissible control region, and the desired dynamics, such as the desired speed and yaw rate; 2) an upper level controller that computes the traction force input and the yaw moment input to track the desired dynamics; and 3) a lower level controller that determines actual actuator commands, such as the front/rear driving motor torques and independent brake torques. The supervisory controller computes the admissible control region, namely, the relationship between the vehicle speed and the maximum curvature of the vehicle considering the maximum steering angle, lateral stability, and rollover prevention. In the lower level controller, a wheel slip controller is designed to keep the slip ratio at each wheel below a limit value. In addition, an optimization-based control allocation strategy is used to map the upper level and wheel slip control inputs to actual actuator commands, taking into account the actuator constraints. Numerical simulation studies have been conducted to evaluate the proposed driving control algorithm. It has been shown from simulation studies that vehicle maneuverability, lateral stability, and rollover mitigation performance can be significantly improved by the proposed driving controller.</P>

Convex Optimization Algorithms for Active Balancing of Humanoid Robots

Juyong Park,Jaeyoung Haan,Park, F.C. IEEE 2007 IEEE TRANSACTIONS ON ROBOTICS Vol.23 No.4

<P>We show that a large class of active balancing problems for legged robots can be framed as a second-order cone programming (SOCP) problem, a convex optimization problem for which efficient and numerically robust algorithms exist. We describe this general SOCP balancing framework, show that several existing optimization-based balancing strategies reduce to special cases of this more general formulation, and investigate the computational performance of our SOCP algorithms through simulation studies involving a humanoid model.</P>

Juyong Kang,Wongun Kim,Soungyong Jung,Jongseok Lee,Kyongsu Yi 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8

This paper describes an autonomous driving control algorithm based on skid steering for Robotic Vehicle with Articulated Suspension (RVAS). The driving control algorithm consists of four parts; speed controller for following a desired speed, trajectory tracking controller which computes a yaw moment input to track a desired trajectory, longitudinal tire force distribution which determines an optimal desired longitudinal tire force and wheel torque controller which determines a wheel torque command at each wheel to keep slip ratio at each wheel below a limit value as well as track the desired tire force. Longitudinal and vertical tire force estimators are designed for optimal tire force distribution and wheel slip control. The dynamic model of RVAS for simulation study is validated using vehicle test data. It is found from simulation and test results that the proposed driving controller produces satisfactory trajectory tracking performance.

가짜뉴스의 개념 및 구성요건에 대한 이해관계자의 인식 연구 : Q방법론을 중심으로

김주용(Juyong Kim) 서울대학교 언론정보연구소 2022 언론정보연구 Vol.59 No.2

가짜뉴스의 개념 및 구성요건, 범주 등에 대한 규제정책행위자나 규제정책대상자와 같은 이해관계자의 인식지형을 파악하고자 Q방법론을 적용한 연구를 실시하였다. 분석결과, <언론책임 엄격주의자> 유형과 <표현의 자유 위축우려론자> 유형, <디지털미디어중심 개념설계론자> 유형의 세 가지 인식유형이 도출되었다. <언론책임 엄격주의자> 유형은 전통언론의 보도라 하더라도 소셜미디어 상의 거짓정보를 사실검증 없이 인용보도하거나 독자를 기만할 의도가 있었던 경우, 부분적 사실로써 전체맥락을 왜곡하는 경우 모두 가짜뉴스가 될 수 있다는 인식을 나타냈다. 이에 비해 <표현의 자유위축우려론자> 유형은 객관주의 저널리즘 규범 위반여부이나 소셜미디어플랫폼 상의 정보인지 여부 등은 가짜뉴스 해당여부의 판단기준이 될 수 없으며, 의견표현의 전제사실이 거짓임을 인지하고 있었다 하더라도, 또 풍자나 패러디뉴스가 맥락을 왜곡해 오해를 유발한다 하더라도 이를 가짜뉴스로 간주할 수는 없다는 인식을 보였다. 한편 <디지털미디어중심 개념설계론자>는 가짜뉴스를 소셜미디어플랫폼 상의 거짓정보로서 인간의 인지적 한계나 편견을 악용하는 방식으로 조작·설계된 것에 한정해서 보아야 한다는 인식을 갖고 있었다. 또한 헌법의 근간을 훼손하는 가짜뉴스에 대해서는 표현의 자유 보호영역에서 배제해야 한다는 인식을 나타냈다. 이상의 분석결과를 토대로 이들 인식유형들이 서로 동의하거나 갈등하는 지점은 어디인지, 세 인식유형 간 타협 가능성을 최대화할 수 있는 가짜뉴스 개념 설계방안은 무엇인지에 대해 논의하였다. For discussions on regulatory policies on fake news to produce productive outcomes, it is necessary to clearly understand what perceptions that various stakeholders surrounding fake news, such as the media, academia, platform businessmen, and civil society, have about issues relevant to regulations on fake news. Therefore, this study identifies stakeholders’ perceptual topographies of the concept of fake news and based on this, it aims to suggest ideas for solutions on compromisable and effective policy making against fake news. By applying Q methodology, to do so, this study first categorized various subjective perceptions of stakeholders on diverse issues related to fake news, such as the concept and components of fake news. Then, the characteristics of each perceptual type derived were analyzed. As a result of the Q analysis, three perceptual types were found: a type of ‘media responsibility rigorists’, a type of ‘shrinkable freedom of expression worriers’, and a type of ‘digital media-focused conceptual designers’. <Media responsibility rigorists> had the perception that traditional media reports that mediate false information on social media platforms without verification of facts, could be regarded as fake news. In addition, if it is a report that completely deviates from journalistic norms such as fairness and objectivity, this type showed a tendency to agree more with such a case that can be regarded as fake news than other types. <Shrinkable freedom of expression worriers> was greatly characterized with the position that freedom of opinion is extremely valued. This type had the perception that even if the media practitioner knew that the expression was false and expressed their opinion based on it, it should not be easily regarded as fake news. <Digital media-focused conceptual designers> showed a tendency to pay attention to the characteristics of cognitive manipulation of fake news produced and distributed under the technical environment of digital media. In addition, regarding reports of intention to deceive in traditional media, they had a position that they should be excluded from the categories of fake news in consideration of the controversy over the infringement of freedom of the press. Furthermore, of those categories, where perceptions between types are similar or conflicting with each other, and what items are likely to be mutually agreed or compromised were reviewed. Finally, based on the above analysis results, measures were suggested to ensure effectiveness while minimizing social conflicts and confrontations in policies related to the conceptual design of fake news.

This paper describes a driving control algorithm based on a skid steering for a Robotic Vehicle with Articulated Suspension (RVAS). The RVAS is a kind of unmanned ground vehicle based on a skid steering using independent in-wheel drive at each wheel. The driving control algorithm consists of four parts: a speed controller for following a desired speed, a lateral motion controller that computes a yaw moment input to track a desired yaw rate or a desired trajectory according to the control mode, a longitudinal tire force distribution algorithm that determines an optimal desired longitudinal tire force and a wheel torque controller that determines a wheel torque command at each wheel in order to keep the slip ratio at each wheel below a limit value as well as to track the desired tire force. The longitudinal and vertical tire force estimators are required for the optimal tire force distribution and wheel slip control. The dynamic model of the RVAS for simulation study is developed and validated using the vehicle test data. Simulation and vehicle tests are conducted in order to evaluate the proposed driving controller. It is found from simulation and vehicle test results that the proposed driving controller provides satisfactory motion control performance according to the control mode.
