Tuberculosis of the vagina is very rare disease reported to be involved in less than 1% of female genital tuberculosis. A 53-year-old woman presented with abnormal cervicographic finding at the private clinic. On vaginal physical examination, there were multiple elevated nodular lesion in the vagina and ectocervical area. There was no abnormal vessels or acetowhite epithelium on colposcopic examination. Direct biopsy for histologic examination revealed granulomatous lesion. We performed PCR of mycobacterial DNA and Ziehl-Neelsen staining for acid-fast bacilli (AFB). The Ziehl-Neelsen staining for AFB was negative, but mycobacterial DNA fragments were detected using the PCR method. Diagnosis was confirmed by the detection of acid-fast bacilli in histologic preparations. Anti-tuberculosis medication was effective for this patient.

풍동실험에서 폐단면(closed section) 풍동을 사용할 경우 벽면에 의하여 유동장의 변화가 생기게 된다. 이는 벽면효과 보정을 통하여 측정된 값을 보정할 수 있다. 벽면효과 보정에는 고전적 방법, 벽면압력 측정방법, CFD 응용방법, 적응벽면 방법 등이 있으나, 일반적으로는 고전적 방법과 벽면압력 측정방법이 사용된다. 본 연구는 기존 연구에서 제시된 다양한 벽면효과 보정방법들에 대해 알아보았다. T-50 5% 모델을 이용하여 받음각 -10~30° 까지 풍속 30m/s에 대한 풍동실험을 진행하였으며 결과에 각 보정 방법들을 적용해보았다. 저받음각에서는 wake 및 separation에 의한 효과가 적어 보정량이 거의 없었다. 고받음각으로 갈수록 simplified 방법에서 보정량이 가장 큰 것을 확인할 수 있었으며, 보정 전과 비교하여 양력계수에서 최대 10%, 항력계수에서 최대 7.9% 보정되었다. 또한 꼬리날개에 대한 효과를 비교하였으며, 피칭모멘트 계수에 영향을 주며 꼬리날개 보정의 유무에 따라 최대 0.05% 정도 보정의 차이가 발생하는 것을 확인할 수 있었다. When a closed section wind tunnel is used, the flow field changes due to the wall . This can correct the measured value through the wall effect correction. There are classical method, wall pressure measurement method, CFD application method, and adaptive wall method, but the classical method and the wall pressure measurement method are generally used for the wall effect correction. This study investigated various wall correction methods proposed by the previous studies. T-50 5% model was used for the wind tunnel test, test wind speed was 30m/s and angle of attacks were -10° ~ 30°. Each correction method were applied to the wind tunnel results. At low angle of attack, due to little effect of wake and separation, there was almost no correction. At the high angle of attack, it was confirmed that the correction amount was the largest in the simplified method. Compared with the corrected and uncorrected results, the maximum lift coefficient and the drag coefficient were corrected by 10% and 7.9%, respectively. In addition, the effect of tail wing was compared, and it was confirmed that there was a difference of correction by 0.05% depending on presence or absence of tail wing correction.

상속인의 점유취득 -역사적 발전과 한국 민법에의 시사점-

최윤석(Choi, Youn-Seok) 한국가족법학회 2017 가족법연구 Vol.31 No.3

Besitz wird im koreanischen Recht - wie auch im deutschen Recht - als tatsächliche Gewalt über eine Sache bezeichnet. Unter den Vorschriften zum Besitz in den §§ 192 ff. Koreanisches Zivilgesetzbuch (KZGB) befinden sich neben den Regelungen zum Besitz auch solche zum Besitzrecht. Das Besitzrecht ist ein dingliches Recht und umfasst alle Rechte sowie Rechtsfolgen, die aufgrund des Besitzes entstehen. § 193 KZGB regelt, dass das Besitzrecht auf den Erben übergeht. Der Unterschied zu § 857 Bürgerliches Gesetzbuch (BGB) besteht darin, dass sich § 193 KZGB sich auf den Übergang des Besitzrechts auf den Erben bezieht; § 857 dagegen den Übergang des Besitzes auf den Erben. Trotz dieser Differenz stützt die herrschende Literatur im koreanischen Recht den Übergang des Besitzes auf § 193 KZGB. In dieser Abhandlung wird der Frage nachgegangen, ob § 193 KZGB oder eine sonstige Vorschrift im KZGB eine taugliche Grundlage für den Übergang des Besitzes auf den Erben bilden kann. Dafür werden die historischen Entwicklungen des § 857 BGB untersucht und deren Bedeutung für das koreanische Zivilrecht herauskristallisiert. Der erste Teil dieser Untersuchung befasst sich mit den historischen Entwicklungen des Erbenbesitzes und reicht bis in das römische Recht sowie das gemeine Recht. Anschließend wird die Gesetzgebungsgeschichte des § 857 BGB näher erörtert. Der Verfasser kommt zu dem Ergebnis, dass es sich beim Erbenbesitz nach seiner historischen Entwicklung um einen fingierten Besitz handelt. Der Erbenbesitz nach koreanischem Recht wird im zweiten Teil dieser Abhandlung im Lichte des Ergebnisses des ersten Teils untersucht. Es wird zunächst festgestellt, dass das Besitzrecht im Sinne des § 193 KZGB nicht dem Besitz im Sinne des § 857 BGB entspricht. Für den Besitzübergang auf den Erben ist der § 193 KZGB somit weder unmittelbar noch analog anwendbar, da es an einer vergleichbaren Rechtslage fehlt. Ebenso wenig erfasst § 199 KZGB die Gesamtnachfolge des Besitzes auf den Erben, weil gemäß § 199 Abs. 1 KZGB der Nachfolger des Besitzes entweder nur seinen Besitz oder seinen Besitz sowie den Besitz seines Vorgängers gemeinsam geltend machen kann. Diese Wahlmöglichkeit ist mit der Gesamtnachfolge im Besitz, bei dem der Besitz des Erblassers unverändert auf den Erben übergeht, nicht vereinbar. Aus diesen Gründen besteht derzeit im koreanischen Recht keine gesetzliche Bestimmung, die den Besitzübergang auf den Erben regelt und demgemäß kein fingierter Erbenbesitz. Diese missliche und unglückliche Rechtslage kann dadurch beseitigt werden, indem der Wortlaut des § 193 KZGB dahingehend geändert wird, dass er nicht den Übergang des Besitzrechts sondern den Übergang des Besitzes regelt.

Much research is going on efficient heat dissipation in electronic devices. Among them, methods to improve cooling performance using ferrofluid are getting much attention. Ferrofluid is a colloidal suspension containing magnetic-nano particles in the base fluid, and it has the characteristic of making flows when an external magnetic field is applied. It can create flows without external power and has the advantage of directly being able to control the flow. In this study, ferrofluid was used as a medium in a fin-tube heat exchanger. The heat transfer in a heat exchanger with the temperature difference was compared. VGs (vortex generators) were installed to form circulations in the inner chamber containing ferrofluid. Through these, it was attempted to improve the cooling performance. By changing AR (aspect ratio) of VGs, numerical analysis was performed to analyze the heat transfer performance. It was concluded that the VGs with 2 mm×11 mm(width×height) had the best heat transfer performance.

목적: 자궁경부암 및 자궁경부 상피내암에서 인유두종바이러스 (HPV)와 cyclooxygenase 2 (COX-2) 발현과의 상관 관계를 알아보고자 하였다. 방법: 각각 14명씩의 자궁경부 상피내암, 자궁경부암 환자의 자궁경부 조직과, 대조군으로는 자궁근종으로 자궁적출술을 받은 14명의 환자들의 자궁경부 조직을 이용하였다. 인유두종바이러스 검출에는 중합효소연쇄반응을 이용하였고, COX-2 검출에는 면역조직화학적 염색을 이용하였다. 결과: 고위험군의 인유두종바이러스 감염은 대조군에 비해 상피내암과 자궁경부암에서 현저히 많이 검출되었다 [상피내암: 11예 (78.6%), 자궁경부암: 14예 (100%), 대조군: 1예 (7.1%), P-value<0.001]. COX-2의 발현 강도는 대조군보다 상피내암이 높았고 (P=0.037), 자궁경부암이 상피내암보다 더 높았다 (P=0.002). 인유두종바이러스가 검출되지 않았던 상피내암 3예에서는 바이러스가 검출되었던 나머지 상피내암에 비하여 COX-2의 발현이 현저히 낮게 나타났다 (P=0.013). COX-2의 발현정도와 인유두종바이러스감염과는 유의한 상관관계를 보였으나 (P<0.001), 다변량 분석에서는 정상 조직에서 상피내암, 침윤암으로의 진행만이 COX-2 과발현에 독립적으로 영향을 주는 인자였다. 결론: COX-2의 과발현에는 정상조직에서 침윤암으로의 진행정도가 고위험 인유두종바이러스감염보다 더 중요한 요인으로 추정된다. Objective: The aim of this study was to identify the relation between HPV infection and cyclooxygenase 2 (COX-2) overexpression in cervical carcinoma in situ (CIS) and carcinoma. Methods: Fourteen patients with CIS, 14 patients with invasive cervical carcinoma, and 14 patients with myoma as control were enrolled. Polymerase chain reaction was used to detect high risk types of HPV, and immunohistochemistry was used to detect COX-2 expression. Results: The frequencies of high risk types of HPV infections in CIS or carcinoma were significantly higher than control [CIS: 11 (78.6%), carcinoma: 14 (100%), control: 1 (7.1%), P-value<0.001]. COX-2 expressions in CIS were higher than control (P=0.037), and those in carcinoma were higher than CIS (P=0.002). Three patients with CIS did not show HPV infection and showed lower COX-2 expression than the other patients with HPV infection in CIS group (P=0.013). There was strong correlation between COX-2 expression and HPV infection (P<0.001). However, in multivariate analysis, disease progression from normal to invasive carcinoma was the only independent factor to affect COX-2 overexpression. Conclusion: Disease progression from normal to invasive carcinoma might be more important factor to affect COX-2 overexpression than high risk types of HPV infection.

不當利得의 體系

최윤석(Choi, Youn-Seok) 한국재산법학회 2014 재산법연구 Vol.31 No.1

우리 학계는 대법원과 함께 종전에 부당이득의 이론적 기초를 공평, 형평 내지 정의의 원칙을 기본으로 하는 통일론(공평설)으로 파악하였다. 현재 이러한 견해와 더불어 비통일론으로서 독일에서 발생한 분리론(유형론)이 등장하면서 유력한 이론으로서 한국의 민법학계에 자리를 잡고 있는 상태다. 우리의 분리론의 주된 논거는 부당이득의 이론적 기초가 통일적으로 설명되지 않는 한계점을 지적하면서 다양한 부당이득의 유형이 존재하며, 이들은 각각의 상이한 기초사상을 갖고 있고, 나아가 "법률상 원인 없이"의 의미도 부당이득의 유형에 따라 다르게 판단되어야 한다는 점이다. 이러한 우리의 분리론은 독일의 분리론의 강한 영향을 받았는데, 독일 부당이득법이 제정된 이후에 새롭게 나타난 독일의 분리론은 독일민법 제812조 제1항 1문이 급부와 그 밖의 방법으로 구분된 부당이득의 유형을 규정하고 있는 이상, 각각의 부당이득 유형은 고유의 구성요건을 필요로 하고 있으며, 특히 각각의 독자적인 기본 사상을 지향한다는 점을 중심으로 한다. 따라서 이러한 분리론과 관련된 실정법상의 근거가 발견되지 않는 우리 민법 제741조로부터 어떻게 분리론을 설명할 수 있는가 하는 의문이 발생한다. 나아가 독일의 분리론 자체도 독일 부당이득법 제정과정을 자세히 검토해 보면 독일민법 입법자가 형평의 원칙하에 부당이득법을 제정한 의도에 맞지 않는 이론으로서, 로마법 이래로 변함없이 형평의 원리하에 계속적으로 발전 및 전승되어온 부당이득 고유의 개념을 혼란스럽게 하는 문제를 야기하고 있다. 따라서 본고에서는 부당이득의 체계와 관련하여 로마법상의 condictio로부터 시작하는 부당이득제도가 다양한 부당이득의 유형을 인정하고 있으며, 또한 형평의 원칙에 연유하고 있다는 점을 근거로 통일론의 입장을 법역사적 해석방법을 통해 논증하고 우리 부당이득법의 개념, 본질 및 체계를 규명하고자 한다. The condictio whose name dates back to legis actio per condictionem is a strictly legal action against individual for certam pecuniam dari or dari aliam certam rem. It provides a uniform action with a single form for certain sum of money or specific things and contains condictio indebiti, condictio ob turpem vel iniustam causam, condictio ob causam datorum, condictio causa data causa non secuta and condictio furtiva. It does not base on the tort law, but derived from the naturalis aequitas. The naturalis aequitas is the equity rule, which is developed by the Greek philosophy, Pomp. D. 12,6,14 : Nam hoc natura aequum est neminem cum alterius detrimento fieri locupletiorem. In Roman law, the action to reclaim enrichment obtained by performance (Leistungskondiktion) was of primary importance and the Roman jurists regarded it as the basic form of condictio. It is noteworthy that they knew the condictio furtiva as a specific action to reclaim enrichment obtained by interference with private property (einzelne Eingriffskondiktion), otherwise a general action to reclaim enrichment obtained by interference with private property (allgemeine Eingriffskondiktion) in German modern sense. Despite the dissolution of the classical condictio in a group of independent right of claims in the Justinian law, the equity rule was maintained as the basis of condictiones. In the 19th century, Friedrich Carl von Savigny established the theory of condictio, which assumes that the condictio is due to a common principle and that the uniform fact of the enrichment can be seen in "causeless enrichment of others from our properties (grundlose Bereicherung des Andern aus unsrem Vermögen)". This is the starting point of the theory of unity. Franz Philipp von Kübel wrote with a faithful image of the Roman legal specific condictiones (Spezialkondiktionen) the partial draft of the law of unjust enrichment of the German Civil Code. He saw the basis of law of unjust enrichment in the shifting of properties under the influence of the theory of Savigny. The first draft accepted Kübel's basic concept. Kübel and 1st Commission opposed the cases of enrichment through willful performance to enrichment without the will of the disadvantaged person. However, the Editorial Committee of the 2nd Commission abandoned the system of specific condictiones of Roman law and established a general clause by taking consideration of simplicity and clarity of the 2nd draft. Although it adhered strictly to the uniform basic principle of naturalis aequitas and focused on the shifting of properties. According to the theory of separation, which was developed by Walter Wilburg and Ernst von Caemmerer, the various condictiones do not go back to a uniform principle. Unlike the Leistungskondiktion, in the case of Eingriffskondiktion as a mainly applicated case of action to reclaim enrichment obtained by non-performance (Nichtleistungskondiktion) it depends on the wrongful act (widerrechtliche Handlung), the interference (Eingriff) with assigned content (Zuweisungsgehalt). But to the contrary, the historical development until the 19th century as well as the legislative materials on the German Civil Code demonstrate that the legislator has written on the German Civil Code under a uniform dogmatic principle of the rules on unjust enrichment. The German legislator neither intended to regulate the Leistungskondiktion and Nichtleistungskondiktion on different bases nor to determine their facts dissimilarly. The rules relating to unjust enrichment in the Korean Civil Code and their interpretation are affected by the doctrines of German law, which has a strong influence on the Korean civil law. This article aims to explore the nature and system of the Korean law on unjust enrichment specifically concerning historical development, beginning from Roman law, and legislative process of the German Civil Code.
