지식가능성 역설과 반사실적 조건 명제에 대한 논파자

김남중 ( Nam Joong Kim ) 한국논리학회 2014 論理硏究 Vol.17 No.1

모든 (의미론적) 반실재론자들은 모종의 검증원칙을 받아들인다. 그 원칙에는 반직관적인 강한 검증원칙과 상대적으로 그럴 듯한 약한 검증원칙의 두 가지 형태가 있다. 당연히 반실재론자들은 약한 검증원칙을 선호해왔는데, 이른바 지식가능성 역설은 사실 그 두 가지 형태의 검증원칙들이 동치라는 사실을 보여준다. 이 문제를 해결하기 위해서 에징튼은 새로운 형태의 검증원칙을 제시하지만, 그녀의 검증원칙 역시 그 나름의 문제점을 안고 있다. 이 난점을 극복하기 위해, 에징튼은 반사실적 조건명제를 이용한 지식모형을 제공한 바 있다. 이 논문에서는 이 지식모형이 심각한 문제점을 안고 있다고 논할 것이다. 익히 알다시피, 비결정론적인 미시적 현상의 세계에서는 극히 낮은 물리적 확률에도 불구하고 간신히 일어나는데 성공하는 사실들이 존재한다. 필자는 이런 사실들과 연관된 반사실적 조건명제는 인식적 논파자의 존재로 말미암아 알려질 수 없으며, 따라서 에징튼의 지식모형은 많은 경우 작동하지 않는다고 논할 것이다. Every (semantic) antirealist accepts one or another form of verification principle. The principle has strong and weak forms, the strong form being highly counterintuitive but the weak one being more plausible. Understandably, antirealists have preferred the weak form of verification principle. Unfortunately, the so-called knowability paradox shows that those two forms are indeed equivalent. To solve this problem, Edgington suggests a yet new form of verification principle. Unfortunately, her new principle has its own difficulty. To overcome this difficulty, Edgington provides a new model of knowledge, according to which every true proposition is somehow associated with a known counterfactual conditional. In this paper, I shall argue that even this new model of knowledge confronts with an insurmountable problem. It is a well-known fact that, in the microscopic levels, some facts manage to occur despite very low physical chances. I will argue that the counterfactuals linked with those facts cannot be known due to the existence of epistemic defeaters. Hence, Edgington`s knowledge model does not work in all cases.

한국 민간경비 발전에 따른 경비업법 개선방향 연구

김남중(Kim, Nam-Joong) 한국민간경비학회 2012 한국민간경비학회보 Vol.11 No.2

한국의 민간경비는 1950년대 초 미8군부대를 경비하면서 시작되었다. 이후 1976년 12월 31일 용역경비업법이 제정되면서 민간경비산업은 성장을 하게 되었다. 1980년대 초부터 선진국 민간경비의 기술과 자본을 도입하면서부터 급속한 성장을 하게 되었고, 86서울아시안게임, 88서울올림픽 등 국제적인 행사에 민간경비업체가 업무에 참여하면서 민간경비는 민생치안 대안으로서 미래 산업의 하나로 각광받게 되었으며, 일반인에게도 대중화되어 양적인 수요도 증가 하였다. 또한, 용역경비업법이 제정 된 후 15차에 걸쳐 소폭 개정 또는 대폭 개정되고, 변화하는 경호경비 환경과 사회변화에 대응하기 위해 제도적으로 보완하면서 많은 노력을 하였다. 그러나 업무의 특성과 직무에 맞지 않는 허가요건 강화, 감독기구의 대체, 이원적 운용체제의 단일화, 배치상문제점, 전문경비인력의 자격화가 문제점으로 도출되었다. 이러한 문제점을 해결하기 위해 경비업자에 대한 자격요건은 객관적이고 신뢰성있는 결격사유로 재구성되어야 하며, 민간경비를 담당하는 기구로서 별도의 기관을 구성하여 청원경찰법과 경비업법의 운용체제를 법률적 단일체제로 구성하여야 한다. 그리고 경비원의 자격기준을 강화시킬수 있는 교육과정을 개선해야한다. 또한 관련대학 및 관련업종 경력자들에게 교육의 일부 면제사항 등을 추가하여 시행될 수 있도록 경비업법이 발전적으로 개선되어야 할 것이다. The private Security Industry of korea began after served security service for the United States army of 8 division. The industry grew up after establish private security regulation on December 31th of 1976. Early 1980’s the industry was accelerated from bringing technical knowledge of developed nations rapidly. Also, private security was gotten into the spotlight by one of futurity industry instead public security after companies performed 86 Asian game and 88 Seoul Olympic successfully. Therefore, the industry became to increase qualitatively and quantitatively. The security law reformed significantly fifteen times, response to the systematic effort to complement in changes of the environmental security guard’s society and social society. However, the business nature of the authority does not meet the job requirements, changing of the director agency, disunity system, placement issues, unqualified security guards issues were produced. To resolve these issues for security guards qualifications need to contain reliablity and objectivity. The security guard institution’s authority needs to be formed independently include security polices law (policeman on the special guard assignment) and the security law. And the private guards and security guards of the eligibility criteria can enhance curriculum should improve. In addition, the relevant university and related sector career training to those who are some of the exclusions will be implemented by adding a guard up so that you can act as constructively dissolve this will be improved.

잠자는 미녀 문제에 대한 가버식 해결책

김남중 ( Nam Joong Kim ) 한국논리학회 2012 論理硏究 Vol.15 No.1

이전 논문(2009)에서 나는 잠자는 미녀 역설에 대한 한 가지 해결책을 제시하였는데, 그에 의하면 미녀가 동전 앞면에 월요일에 부여하는 확률은 1/2보다 낮아야 한다. 이것은 물론 1/3주의에 유리한 결론이다. 그렇지만 내가 1/3주의를 성공적으로 옹호했다고 할지라도, 한 가지 중요한 물음이 남는다: 왜 1/2주의는 틀렸는가? 그들의 주요 논변은 간단하다: 잠자는 미녀는 동전이 어떻게 땅에 떨어지는지에 대한 새로운 증거를 받지 못했기 때문에, 그녀가 그가능성에 부여하는 확률은 이전과 같아야 한다. 이제 다음 사실에 주목해 보자: 만일 1/3입장이 옳다면 잠자는 미녀 역설은 이른바 오래된 증거 문제의 새로운 예가 될 것이다. 이 논문에서 나는 새롭고 직접적으로 관련된 증거가 없음에도 왜 잠자는 미녀가 그녀의 믿음의 정도를 바꿀 수 있는지 대니얼 가버(1983)가 오래된 증거 문제에 대해 내놓은 해결책을 가지고 설명할 것이다. In my previous paper (2009), I defended a solution of the Sleeping Beauty problem, according to which, on Monday, Sleeping Beauty assigns a lower credence to the coin`s landing heads than 1/2. This conclusion was largely favorable to the Thirder view. However, even if my defense of the Thirder view was successful, it left one important question to be unanswered: Where did the Halfers go wrong? Their main argument was simple: Because Sleeping Beauty does not receive new and relevant evidence about how the coin lands, her credence in its landing heads should remain to be the same. But note that, if the Thirder view was right and Sleeping Beauty receives no new and relevant evidence, then this becomes a special case of the so-called old evidence problem (Glymour, 1980). In this paper, I will explain why it is rational for Sleeping Beauty to change her credence despite the lack of new evidence about the coin`s landing heads. For this explanation, I will use Garber`s well-known solution to the old evidence problem.

Somatotropin 이식 제형 개발과 지속적 방출 효과

김남중,Kim, Nam-Joong 대한수의학회 2008 大韓獸醫學會誌 Vol.48 No.1

The present study was carried out to develop a sustained release implantable formula of bovine somatotropin (SRIF-BST) and to examine its sustained release effect. The SRIF-BST was produced by coating a solid pellet, which was comprised of BST and an excipient, made of a biodegradable polymer and poloxamer, which are capable of regulating the rate of BST release. The coated membrane of SRIFBST was observed with a field emission scanning electron microscope. The thickness of the coated membrane was approximately $1{\mu}m$, and the pore sizes of the coated membrane surface were below $10{\mu}m$. In dissolution test, the release duration of the SRIF-BST maintained for 10 days, whereas the release duration of the control BST formula maintained for 3 days. In weight gain assay and tibia test of hypophysectomized rats, the release duration of the SRIF-BST treated group was 12 days and the net weight gain was 53.16 g, also the tibia length and strength of the SRIF-BST treated group was increased 10.5% and 23.1% compared with those of the control group, respectively.

The present study was carried out to examine the effect of insulin formula on blood glucose change in normal Sprague-Dawley male rats. Also, this study was performed to investigate the feasibility of oral insulin formula development. To administrate the insulin formula into intestine, the surgical technique, celiotomy, was performed in rats. Insulin formula was administrated at a dose of 24.5 IU/kg via duodenum, ileum, and colon of the rats, and the blood glucose level was measured. For the comparison, the vehicle without insulin was administrated into ileum via celiotomy. Also, this insulin formula was administrated into rats orally using sonde and the same parameter was treasured. The bloods of all groups were collected from tail veins using syringes at given time interval. Orally administrated group did not show the change of blood glucose level and control group slightly show the change of blood glucose level at 1 hour after celiotomy. All intestinally administrated groups showed the change of blood glucose level. Among the tested groups, ileac administration group and colonic administration group showed the significant change of blood glucose level. Particularly, ileac administration group showed the lowest blood glucose level. To calculate the bioavailability of intestinal and oral administration, insulin solution was injected subcutaneosly, common insulin injection route, into another normal rats. The bioavailability of ileac group was 8.3% when compared with subcutaneous injection, duodenal group was 1.8%, colonic group was 4.2%, and oral group was 0.2%, respectively.

비육우, 젖소 및 비육돈에서 이식형 소마토트로핀 지속성 제형의 유효성 시험 연구

김남중,Kim, Nam Joong 대한수의학회 2011 大韓獸醫學會誌 Vol.51 No.1

Sixteen steers were used to investigate the efficacy of the sustained-release implant of bovine somatotropin (bST) in improving growth and feed:gain ratio during 12 weeks. Administration of the 400 mg bST implant resulted in a 16.1% increase in growth rate, and this increase was significant (p<.05). The use of the sustained-release implant did not alter (p>.05) feed intake and feed:gain ratio. Thirty-four cows were used to investigate the efficacy of the sustained-release implant of bST in milk production during 4 weeks. Administration of the 200 mg bST implant resulted in an 8.7% increase in milk production, and this increase was significant (p<.05). Twenty-four barrows were used to investigate the efficacy of the sustained-release implant of porcine somatotropin (pST) in improving growth, feed:gain ratio and backfat thickness during 6 weeks. Administration of the 120 mg pST implant resulted in a 11.4% increase in feed:gain ratio and a 60% decrease in backfat thickness, and these results were significant (p<.05). But the use of the sustained-release implant did not alter (p>.05) growth rate and feed intake.

비육우에서 이식형 bovine somatotropin 지속성 제형의 blood profile test

김남중,Kim, Nam Joong 대한수의학회 2009 大韓獸醫學會誌 Vol.49 No.1

The present study was carried out to examine the sustained release effect of the implantable bovine somatotropin (SRI-BST) formula. In the blood profile test in steers, the bovine somatotropin concentration in serum by radioimmunoassay showed the peak concentration on the first day after the implantation of the SRI-BST formula, and concentration proceeded for 5 days (p < 0.05). The insulin-like growth factor-1 concentration showed the peak concentration on the seventh day after implantation of the SRIF-BST formula, and concentration proceeded for 10 days (p < 0.05). The glucose showed the peak concentration on the first day after implantation of the SRI-BST formula, and concentration continued for 3 days (p < 0.05). The blood urea nitrogen showed the lowest concentration on the third day after implantation of the SRI-BST formula, and concentration continued for 7 days (p < 0.05). These results proved that the SRIF-BST formula was the sustained release effects in steers.
