가격역전과 관련한 맑스의 자본개념의 정합성 연구 - 박만섭(2006)과 류동민(2006)의 문제제기에 답하며
박지웅(Park Ji-Ung) 한국사회경제학회 2008 사회경제평론 Vol.- No.30
본 논문은 가격역전에 관한 논쟁에서 필자의 입장을 정리한 것이다. 필자는 가격역전에 대한 박만섭(2006)의 정의를 수용하여 가격역전의 가능성을 타진하였다. 물론 2생산물체계에 가격역전의 불가능성을 보여 주었다. 그러나 n생산물체계에서 가격역전은 발생한다. 가격역전은 Marx의 전형규칙(류동민, 2006)의 성립과 무관하지 않다. 투하노동접근에서 가격역전은 Marx의 전형규칙을 위배한다. 그러나 오늘날 가치론에서 양대조류를 형성하고 있는 비이원론적 접근과 신해석은 그렇지 않다. 특히 비이원론적 접근은 문제의 소지가 될 것이 아예 없다. 그러나 occ(가치텀에 의한 자본의 구성)없이 pcc(가격텀에 의한 자본의 구성)만으로 Marx의 이론을 재구성할 수 있을지 의문이다. 마찬가지로 총가치와 총가격의 괴리를 허용하고 있는 신해석 역시 pcc가 occ를 경향적으로 반영하고 있음을 보여줘야 한다. 이러한 과제를 해결한다면 가격역전은 임의의 두 상품(자본집약적 상품과 노동집약적 상품이 아니다)에 대한 가격변화일 뿐 전형규칙을 둘러싼 개별상품의 가치와 가격의 미시적 관계에 어떠한 교란으로 작용하지 않는다. 이런 측면에서 2생산물체계에서의 가격역전불가능성은 n생산물체계에서 발생한 가격역전으로 이론적 의의를 상실하는 것이 아니라 pcc가 occ를 경향적으로 반영하고 있음을 보여주는 좋은 하나의 예일 것이다. This article evaluates the controversy on price reversal in the light of Marxian value theory. There is no the price reversal in two products system (though M. Park"s definition of price reversal was accepted). But price reversal generally occurs in n-product system. Of special interest is that Marx"s transformation rule is disturbed by price reversal in the dualistic approach (e.g. the embodied labor theory of value). But this is not so in the nondualistic approach and the new interpretation. In this article, I have explored these various issues related to price reversal.

상하지 재건을 위한 유리피판 공여부로서 전측대퇴부의 신뢰성
박지웅,조상헌,어수락,Park, Ji-Ung,Cho, Sang-Hun,Eo, Su-Rak 대한미세수술학회 2007 Archives of reconstructive microsurgery Vol.16 No.1
With the advent of microsurgery, perforator free flap is nowadays considered the first choice for reconstruction of the extensive defect of the extremities because of their moderate thickness. Among them, anterior (anterolateral and anteromedial) thigh perforator free flaps provide the first choice for reconstruction of various soft tissue defects of the extremities with many advantage such as its large, uniform thickness, long vascular pedicle with proper vessel size and minimal donor site morbidity. But, it has still some criticism of unreliable perforators which makes us very careful in elevating the flap. Between March of 2006 and February of 2007, we treated 7 patients of soft tissue defects in the hand and lower extremities with anterior thigh perforator free flap at Hallym and DongGuk University Hospital. We performed 6 anterolateral thigh perforator free flaps based on the descending branch of lateral circumflex femoral artery (LCFA) and 1 anteromedial thigh perforator free flap based on the innominate branch of the LCFA. While approaching for the anterolateral thigh free flap, we happen to meet the cases which we should change into the anteromedial thigh free flap uneventfully on the operating field. In contrast to the original design of anterolateral thigh free flap, we had to harvest the anteromedial thigh perforator free flap in 1 case. All the anterior thigh perforator free flaps survived completely except 1 case of partial necrosis due to venous congestion. Donor sites were closed primarily and healed uneventfully within 2 weeks. Patients were satisfied with the functionally and aesthetically acceptable results. Although doppler sonography is strongly recommended preoperatively in planning the anterior thigh perforator free flaps, we should always remember the variation in vascular anatomy and be ready to change the flap choice from the anterolateral to anteromedial intraoperatively. we provide a review of the literature and present our series of anterior thigh perforator free flaps for reconstruction of the extremities.

가토모델에서 Lipo-PGE1이 복합조직이식편의 미세혈관신생에 미치는 영향
박지웅,어수락,조상헌,최종순,김어진,Park, Ji-Ung,Eo, Su-Rak,Cho, Sang-Hun,Choi, Jong-Sun,Kim, Eo-Jin 대한성형외과학회 2010 Archives of Plastic Surgery Vol.37 No.6
Purpose: The survival of composite graft is dependent on three steps, (1) plasmatic imbibitions, (2) inosculation, and (3) neovascularization. Among the many trials to increase the survival rate of composite graft, prostaglandin E1 (PGE1) has beneficial effects on the microcirculatory level with vasodilating, antithrombotic, anti-inflammatory and neoangiogenic properties. Lipo-PGE1 which is lipid microspheres containing PGE1 had developed to compensate the systemic and local side effects of PGE1. This study was proposed to determine whether Lipo-PGE1 administration enhanced the survival of composite graft through neovascularization quantitatively in a rabbit ear model. Methods: Fourteen New Zealand White Rabbits each weighing 3~4 kg were divided in two groups: (1) intravenous Lipo-PGE1 injection group and (2) control group. A $2{\times}1\;cm$ sized, full-thickness rectangular composite graft was harvested in each auricle. Then, the graft was reaaproximated in situ using a 5-0 nylon suture. For the experimental group, $3{\mu}g$/kg/day of Lipo-PGE1 ($5{\mu}g$/mL) was administered intravenously through the marginal vein of the ear for 14 days. The control group was received no pharmacologic treatment. On the 14th postoperative day, composite graft of the ear was harvested and immunochemistry staining used Monoclonal mouse anti-CD 31 antibody was performed. Neoangiogenesis was quantified by counting the vessels that showed luminal structures surrounded by the brown color-stained epithelium and counted from 10 random high-power fields (400x) by independent blinded observer. Statistical analysis (Wilcoxon Signed Ranks test for nonparametric data) was performed using SPSS v12.0, with values of p<0.05 considered significant. Results: The mean number of the microvessels was $15.48{\pm}8.65$ in the experimental group and $9.82{\pm}7.25$ in the control group (p=0.028). Conclusion: The use of Lipo-PGE1 facilitated the neoangiogenesis, resulted in the improvement of the survival rate of graft. On the basis of this results, we could support wider application of Lipo-PGE1 for more effective therapeutic angiogenesis and successful survival in various cases of composite graft in the human.

박지웅(Park, Ji-Ung) 한국사회경제학회 2014 사회경제평론 Vol.- No.45
이 글의 목적은 불합리하기 짝이 없는 NINJA론을 가능하게 하는 책임부재의 논리를 찾는 것이다. 이러한 논리는 ‘빌 게이츠의 딸과 결혼하기’로 잘 알려진 유머에서 적용되는 논리적 구도와 일치한다. 이러한 논리적 구도는 상호의 존적 명제들(interdependent statements) 간에 야기하는 딜레마에 빠진다. 이 경우 불가능을 가능하게 하는 보증의 마술이 펼쳐진다. 중요한 사실은 이런 황당한 사태를 야기한 보증에 대해서 정작 책임을 문책조차 할 수 없다는 것이다. 문제는 이러한 논리구도가 우화에 그치지 않고 현실에 적용된다는 점이다. 그 대표적인 예가 NINJA론이다. 황당한 NINJA론은 오늘날 관행화 되어 있는 담보대출에서 파생된 것이다. 물론 NINJA론은 금융거래자들의 탐욕이 저지른 최악의 산물이다. 그러나 NINJA론은 단순히 탐욕에 의해서가 아니라 책임부재를 야기하며 탐욕을 부추기는 내재적 논리에 의해 발생된 산물이다. The purpose of this paper is to find the logic causing the absence of responsibility in absurd NINJA loan. This logic correspond with the logic scheme of the well known humor of ‘the fool’s marriage with Bill Gates’s daughter’. This logic scheme fall into dilemma between interdependent statements. In this case, the magic of guarantee is performed, which makes impossibility possible. What is important is that this guarantee causes the absence of responsibility. Problem is that the logic scheme is applied to reality beyond the fable. This example is NINJA loan. This paper shows that NINJA loan results from inherent logic causing the absence of responsibility as well as the greed.

노동-가치-가격의 양적 관계에 관한 논리적 정합성 연구
박지웅 ( Park Ji Ung ) 한국경제학회 2004 經濟學硏究 Vol.52 No.1
According to the non-dualism approach, there was no logical inconsistency in the transformation of value into prices. But the value scheme is incomplete and it is necessary to complement the analysis on quantitative relations between labour time and prices in the aggregate. As we have seen in the dualism approach, the equalities of labour time and prices in the aggregate are no longer compatible with one another simultaneously. For example, the price (x) of total net products is generally different from total direct labour (L_(d)=1) under the numeraire: the price of total constant ccapital = the total indirect labour (i,e., C=c). This paper is focused on finding the law which makes the aggregate inequality. In this paper. this law is specified as follows. The first condition is (dx)/(dc)_(de=0) >0, and the second condition is (dx)/(dc)_(de=0) < (x)/(c), where ℓ is the rate of surplus value. The two conditions are necessary conditions for the profitability of total capital. These conditions are general properties in the input/output model. Especially, we can prove that these conditions are satisfied in the two product system. Under this law, price changes within the limit of predictable magnitude. Although masses weigh differently, it is hard to say that masses are not related to weight, We can think that value is to price as mass is to weight. Therefore, even though not ensuring equalities between labout time and prices in the aggregate, we can insist that prices are quantitatively regulated by labour. Under this law, we also don`t need to set up the concepts of value in a restrictive way. There is no reason why value is labour itself. We can variously set up value as an analytical tool to contemporary capitalism
