홉스의 『시민론』과 『인간론』을 중심으로 본 인권과 전쟁의 권리

이준호 ( Jun-ho Lee ) 서양근대철학회 2018 근대철학 Vol.12 No.-

이 글은 고 이준호 박사의 유고논문이다. 저자가 세운 이 글의 목적은 분명하다. 홉스 연구자들이 『리바이어던』을 main text로 삼고 있는 것에서 벗어나 『시민론』과 『인간론』의 중요성에 주목하고 있다. 필자는 홉스의 시민론을 직접 우리말로 번역한 바 있다. 이 번역 작업을 통해 시민론에 대한 깊은 이해와 성찰을 바탕으로 홉스 정치철학을 새롭게 해석할 가능성을 모색하고 있다. 그가 주목한 새로운 해석이란, 『시민론』에서 홉스는 전쟁을 적극적으로 반대하고 있다는 사실과 신민들의 인권 보호와 복지 증진을 위해 군주가 져야할 자연적 의무가 있다는 것을 보여주는 일이다. 또 최고통치권자에게 복종해야만 하는 근거는 통치권자 자신이 소유한 힘에 대한 ‘공포’에 있지 않고, 실정법을 위반했을 때 받게 되는 처벌의 공포에 무게 중심을 두고 있다. 3절에서 필자는 국가의 두 기원, 동의와 정복에 관해 분석하고 있다. 이 절에서 필자는 실질적 사회계약론에 대해 의문을 제기하고 있다. 애초 국가는 자연발생적으로 시작되었으며, 최고 통치권자의 자의적 통치를 견제하기 위해 신민들과 계약을 맺게 된 것이라는 필자의 해석이다. 4절에서 필자는 시민론의 열 번째 자연법에 주목하고 있다. 공정성, 즉 차별하지 말라는 자연법의 명령은 국가의 평화와 안위를 위해서 통치권자가 지켜야 할 덕목이라는 것이다. 특히 분배의 공정성을 유지하는 일이 통치권자의 의무이다. 5절은 통치권력의 절대성과 복종에 대해 설명하고 있다. 정당화된 권력은 국가의 안전을 위해 신민들의 사생활까지 감시할 수 있어야 한다고 주장한다. 당연히 오늘날의 시각에서 보면 인권침해의 위험이 있지만 홉스 당시에는 문제가 되지 않는다. 그러나 홉스는 부당한 권력에 대해서는 자발적 복종의 의무를 배제하고 있다. 통치권자도 양심과 자연법에 따라 통치할 때만 권력은 정당화되며, 신민들의 자발적 복종을 얻을 수 있다. 6절에서 필자는 자연법을 위반한 통치권자에 대한 전쟁의 권리에 대해 설명하고 있다. 신민을 적으로 만든 통치권자는 그 권력의 정당성을 상실하게 되고, 신민들은 통치권자를 향해 전쟁의 권리를 회복하게 된다는 것이다. 챨스 1세의 처형이 이에 해당된다. 결론에서는 홉스의 정치철학사적 위치를 다시 규정하고 있다. 홉스는 절대왕권주의를 지지하면서도 주권재민론의 선구자로서의 자리매김을 하고 있다. This is a paper by Dr. Lee Jun-ho who died a few years ago. The purpose of this article is clear. Dr. Lee suggests that Hobbes researchers should pay attention to the importance of De Cive and De Homine, not to consider Leviathan as the main work of Hobbes. He translated Hobbes’ De Cive and De Homine into Korean. Through this translation work, he was looking for a possibility to interpret Hobbes’ political philosophy based on deep understanding and reflection on civil theory. The new interpretation he notices is that Hobbes is actively opposed to war in the De Cive and shows that there is a natural obligation of the monarch to protect the human rights and welfare of the people. The author emphasizes that the reason for submitting to the supreme ruler is not the “fear” of the powers held by the ruling power, but the fear of punishment in violation of the law. In section 3, the author analyzes the origins of consent and conquest. In this section, he questions the actual social contract theory. It is his interpretation that the country originally started spontaneously and that it had entered into a contract with the people to check the arbitrary rule of the supreme ruler. In section 5, the author explains the absoluteness and obedience of ruling power. He maintains that justified power has to monitor the privacy of the people for the sake of national security. Of course, from today’s point of view there is a risk of human rights violations, but it is not a problem at the time. However, Hobbes excludes the obligation of voluntary obedience to unjust power. Only when the ruling power is governed by conscience and natural law, power is justified and the voluntary obedience of the people can be obtained. In section 6, the author explains the right of war to the rulers who violate natural law. The rulers who have made the enemies of the people lose the legitimacy of their power, and the people will regain the right of war to the rulers. This is the execution of Charles I. In conclusion, the author redefines the historical location of Hobbes’s political philosophy. According to the author, Hobbes has always been a pioneer of sovereignty, while supporting absolutism.

Experimental Evaluation of Q-Parameterization Control for the Imbalance Compensation of Magnetic Bearing Syatem

이준호,김현기,이정석,이기서,Lee, Jun-Ho,Kim, Hyeon-Gi,Lee, Jeong-Seok,Lee, Gi-Seo 대한전기학회 1999 전기학회논문지A Vol.48 No.3

This paper utilizes the method of Q-parameterization control to design a controller which solves the problem of imbalance in magnetic bearing systems. There are two methods to solve this problem using feedback controal. The first method is to compensate for the imbalance forces by generating opposing forces on the bearing surface (imbalance compensation). The second method is to make the rotor rotate around its axis of inertia (automatic balancing);in this case no imbalance forces will be generated. In this paper we deal with only imbalance compensation. The free parameter of the Q-parameterization controller is chosen such that these goals are achieved. After the introduction of a model of the magnetic bearing system, we explain the Q-parameterization controller design of the magnetic bearing system with emphasis on the rejection of sinusoidal disturbance for imbalance compensation design. The design objectives are formulated as a linear equations in the controller free paramete Q. Finally, simulation and experimental results are presented and showed the robustness and effectiveness of the proposed controllers.

Objectives : This study was carried out to investigate the cause, magnitude and transmission route of the cholera outbreak in 2001 Methods : The study population were those persons who ingested foods at the restaurant, were confirmed as cholera patients, had symptoms of diarrhea and sewed as workers at the restaurant. A questionnaire survey and microbiological examinations on the microbes isolated from rectal swabs were conducted. Of the cases, 316 food histories were surveyed by an analysis of the restaurant menu. Results : There were 139 confirmed cases of cholera reported in Korea in 2001. Of these, 104 were related to the restaurant. By region, Gyeongsangbuk-do had the highest incidence with 91 cases. Of these 91 cases, 74 had ingested foods at the restaurant, 2 were employees and 3 were secondary infection cases within the families. The results of the odds ratio analysis of the 316 persons having ingested foods at the restaurant were as follows: sandwiches 5.07 (95% CI, 1.85-14.59), soybean curd 2.45 (95% CI, 1.09-5.56), noodles 2.34 (95% CI, 1.24-4.42), steamed squid 2.01 (95% CI, 1.17-3.47) and vinegared rice 1.82 (95%, CI, 1.08-3.09). It was certain the restaurant in question was the cause of the 2001 outbreak. Conclusions : We suspected that more than one restaurant employee contaminated foods served at the restaurant. In addition, eating raw fishes purchased at the Pohang Fisheries infected the employees of the restaurant. There is a possibility that these raw fishes were themselves contaminated by cholera bacilli in the sea.

After full opening of distribution market in 1996, its competitiveness was lost and declined due to the emergence of a variety of distribution types, change of customers consumption habits, and purchase patterns. Therefore, Korean government began to support the modernization projects of traditional markets through the establishment of law for the activation of existing traditional markets. In this regard, this study attempts to diagnose the problems of facility modernization projects through substantial and concrete effect analysis on facility modernization projects to provide the activation methods effectively. To achieve this goal, we analyzed the overall satisfaction and substantial effect of facility modernization projects for traditional markes by carrying out questionnaire surveys on merchants at Jun-gang Yudeung Market in Jinju. As a result of questionnaire survey, customers were generally satisfied with the facility modernization project, the market environment was improved and the customer numbers and sales amount which show the actual improvement also increased after implementing the projects. Also, it was proved that customer numbers and the sales amount after the facility modernization project of traditional markets increased and the degree in the increase was low level of 5~20%. Therefore, it was analyzed that sub-project items of the facility modernization project, which have a significant effect on the activation of traditional markets, had a low level of influence.

Warped Common Acoustical Pole and Zero 방법을 이용한 효율적인 공간 등화

이준호,박영철,윤대희,이석필,Lee, Jun-Ho,Park, Young-Cheol,Youn, Dae-Hee,Lee, Seok-Pil 한국음향학회 2009 韓國音響學會誌 Vol.28 No.1

본 논문에서는 warped common acoustical pole and zero (WCAPZ) 모델링 방법을 이용한 새로운 공간 등화 방법을 제안한다. 제안한 방법은 저주파 영역의 등화 성능을 감소시키지 않으면서 등화 필터의 차수를 줄일 수 있는 장점을 가진다. 따라서 제안된 공간 등화 시스템은 기존의 블록 변환 방법에 비해 연산량은 비슷하면서도 적은 입출력 지연을 가지게 된다. 컴퓨터 모의실험을 통해 제안된 방법이 기존의 기법에 비해 저주파 영역에서 좋은 공간 등화 성능을 보임을 검증하였다. This paper presents a new method of designing room equalization filters using a warped common acoustical pole and zero (WCAPZ) modeling. The proposed method is capable of significantly reducing the order of the equalization filters without sacrificing the filter performance, especially, at low frequencies. Thus, the associated input-output delay is much smaller than the conventional block transform method while its computational complexity is comparable to it. The computational complexity also is still comparable to the conventional room equalization method, since the filter is implemented in the linear frequency domain after the pole-zero dewarping. Simulation results confirm that the use of the proposed algorithm significantly improves the room equalization over a range of low frequencies.

레드비트 추출물의 항산화 활성 및 레드비트를 첨가한 돈육패티의 냉장저장 중 이화학적 성상 및 미생물의 변화

이준호,진구복,Lee, Jun-Ho,Chin, Koo-Bok 한국축산식품학회 2012 한국축산식품학회지 Vol.32 No.4

본 연구는 인공합성 항산화제를 대신할 천연 추출물을 사용한 항산화제 개발을 목적으로 레드비트를 이용하였다. 먼저 항산화 활성을 알아보기 위하여 레드비트 에탄올 추출물(RBW)과 레드비트 물 추출물(RBW)을 각각(0.05-1.0%) 농도로 희석하여 항산화 활성을 평가하였다. 그 결과 DPPH 라디칼 소거능과 철이온 흡착력에서 레드비트물 추출물(RBW)이 레드비트 에탄올 추출물(RBE) 보다 유의적 차이를 보이며 더 높은 활성을 보였다(p<0.05). 특히 철이온 흡착력에서 RBW는 0.1% 농도부터 87.0%의 높은 활성을 보였고, 1.0% 첨가에서는 100%의 활성을 보였다. 또한 DPPH 라디칼 소거능에서도 0.25%부터 60% 정도의 높은 활성을 보였다. 반면, 환원력에서는 RBE가 유의적으로 더 높은 활성을 보였다(p<0.05). Linoleic acid 과산화 억제능에서는 두 처리구간 유의적인 차이를 보이지 않았지만(p>0.05), RBW는 모든 농도에서 83% 이상의 활성을 보였고, RBE는 0.05%에서 80% 정도의 활성을 보였다. 이를 토대로 0.5%의 RBE와 RBW를 각각 돈육패티에 적용하였고, 참조구로는 BHT 0.01%를 이용하여 저장기간 동안(0-14일) 이화학적 특성 및 미생물 검사를 실시하였다. 그 결과 백색도와 황색도는 처리구별, 그리고 저장기간에 따른 유의적인 차이를 보이지 않았으며(p<0.05), pH와 적색도는 저장기간이 길어짐에 따라 유의적으로 더 높아졌다(p>0.05). 미생물에서는 총균과 대장균군 모두 참조구가 다른 처리구와 유의적으로 낮은 값을 보였고(p>0.05), 저장기간이 경과함에 따라 유의적인 차이를 보이며 증가하였다(p>0.05). 그리고 지방산화 억제 활성을 평가한 TBARS에서는 냉장 저장 중 대조구(CTL)가 유의적으로 가장 높은 값을 보였고, 레드비트 처리구와 유의적인 차이를 보였다(p<0.05). 특별히 레드비틀 첨가한 TRT1과 TRT2는 저장기간 동안 REF와 유의적인 차이를 보이지 않아(p<0.05) 우수한 지방산화 억제능력을 보였다. This study was performed in order to evaluate the antioxidant activities of red beet extracts as well as the physicochemical properties and microbial changes of pork patties containing red beet during refrigerated storage. Red beet was extracted with water and ethanol. Red beet water extracts (RBW) and red beet ethanol extracts (RBE) were diluted with various concentrations (0.05~1.0%). DPPH radical scavenging activity and iron chelation activity of RBW showed a higher level than those of RBE (p<0.05). In particular, the iron chelation activity of RBW was over 53.4% at all levels. In addition, RBW at 1% had nearly 100% activity. On the other hand, the reducing powers of RBE were higher than those of RBW (p<0.05), and the antioxidant activity on linoleic acid emulsion of RBW was over 83% at all levels. Based on these model studies, 0.5% levels of RBW and RBE were added to ground pork patties (GPP), and the physicochemical properties and microbial changes of red beet GPP were evaluated during storage (0~14 d) at $4^{\circ}C$. The pH and microbial counts increased with increased storage time (p<0.05). Pork patties with BHT showed the lowest thiobarbituric acid reactive substances (TBARS) and microbial counts, and those with red beet had lower TBARS than the control (p<0.05). These results indicated that both red beet water and ethanol extracts could be used as natural antioxidants of pork patties during storage.
