The objects of the nature have three dimensional (3-D) parameters. The 3-D profiles are embedded on the photographs and microscopic images. To understand 3-D configuration, stereo pair image with thick section is frequently employed. The perception of 3-D images is possible with the aid of stereoscopic glasses, although the expert can perceive 3-D images without the glasses. Anaglyphic stereo images are constructed by various softwares from commercial and freeware. Here we would like to present an easy anaglyphs construction method with Adobe $Photoshop^{(R)}$ based on tilting paired images from high voltage electron microscope. The anaglyphic stereo images constructed revealed the same 3-D perception with conventional stereoscopy. We could zoom in/out the anaglyph image digitally to investigate the detail configuration by real time. This method is expected to contribute to understanding complex structures 3 dimensionally.

중첩격자를 이용한 3차원 압축성 Navier-Stokes 코드를 사용하여 정지비행 로터 주위의 유동장을 해석하였다. 후류격자의 간격, 수치기법의 정확도, 난류 모델 등에 따른 유동코드의 수치특성을 확인하였다. 두 가지 형태의 중첩격자 시스템을 사용하여 계산을 수행하였다. 공력 및 끝단 와류의 거동을 Caradonna 동의 실험과 비교하였다. 표면 압력분포 및 끝단 와류의 거동은 실험값과 잘 일치하였다. 적용한 수치해석 기법에 따라 압력분포는 거의 변화가 없는 반면, 후류의 거동은 상당히 큰 편차를 보였다. 자동화된 Cut-paste 알고리즘을 사용한 Chimera 기법을 사용했을 때의 결과는 예상과 달리 기존의 Chimera 기법을 사용하였을 때보다 더 약한 와류 강도를 보였다. A 3-D compressible Navier-Stokes solver using overlapped grids is developed to predict a flow-field around a hovering rotor. The flow solver is verified by a parametric study with the grid spacing of wake grid, spatial accuracy and turbulence model. Computations are performed with different Chimera grid systems. Computational results are compared with the experimental data of Caradonna et al. for both blade loading and the tip vortex behavior. Numerical results show good agreements with experiments for the distribution of surface pressure and tip vortex behavior. Pressure distributions over the blade have marginal differences for different numerical methods, whereas large discrepancies are seen in the prediction of the wake behavior. Results unexpectedly show that the vortex strength from an automated cut-paste Chimera grid is weaker than that from the conventional Chimera grid.

About 25% of patients with breast cancer develop one of the several clinicopathological types of cutaneous metastasis. Telangiectatic cutaneous metastases are very rare and may present with telangiectasia, erythema, papulovesicles, purpuric patch or plaque. Histopathologically, they demonstrate ectatic, dilated dermal blood vessels that contain atypical tumor cells and thrombi. We report a rare case of telangiectatic metastatic breast carcinoma on the scalp and shin, which presented with cutaneous angiosarcoma-like violaceous plaques. (Korean J Dermatol 2008;46(7):933∼936)

The adverse effects of BCG vaccination span diversely from systemic to local reactions. However, the adverse effects of BCG vaccination on the skin are rare and these can appear as non-specific or specific skin reactions. We experienced two cases of non-specific skin reaction, which occurred on a vaccine-injected site. Eczematous lesions with the clinical and pathological findings have not previously been report in the English dermatologic literature. Herein, we present two interesting cases of non-specific skin reactions from dermatological complications of BCG vaccination. (Korean J Dermatol 2007;45(2):165~167)

파생상품 거래의 배임죄 성부에 관한 쟁점 검토 -대상판결: 대법원 2008.5. 29. 선고, 2005도4640 판결-

김지웅(KIM JEE WOONG) 인하대학교 법학연구소 2020 法學硏究 Vol.23 No.1

최근 Total Return Swap(이하 ‘TRS’) 등 파생상품 거래로 인하여 소비자 피해 등 많은 사회적 문제가 야기된 바 있으며, 이에 따라 그 거래와 연관된 금융회사 및 임직원에 대한 형사적 책임도 문제가 되고 있다. 대상판결은 선고된 지 여러 해가 지났지만, TRS, 옵션계약 등 다양한 유형의 파생상품 거래에 관하여, 경영판단, 기수시기, 이득액 산정 등 배임죄와 관련한 여러 논점을 담고 있다는 점에서 검토할 가치가 있다. 먼저, 대상판결 사안에서 피고인들(기업집단에 속한 계열사의 대표이사 및 임원)은 계열사 해외 법인들로 하여금 영업과 상관없이 이 사건 옵션계약 및 화해계약을 체결한 것은 경영판단에 따른 것으로 배임죄의 고의가 없다고 주장하였다. 그러나 대상판결은 “계열그룹 전체의 회생을 위한다는 목적에서 이루어진 행위로서 그 행위의 결과가 일부 본인을 위한 측면이 있다 하더라도 본인의 이익을 위한다는 의사는 부수적일 뿐이고, 이득 또는 가해의 의사가 주된 것임이 판명되면 배임죄의 고의를 부정할 수 없다”고 판시하였다. 최근 대법원은 동일한 기업집단에 속한 계열회사 사이의 지원행위가 경영판단의 범위 내에서 행한 것인지를 판단하기 위한 기준을 제시한 바 있는데(대법원 2017.11.9 선고2015도12633 판결), 이러한 기준에 의하더라도 대상판결 사안에 대해서는 배임죄를 부정하기는 어렵다고 생각한다. 한편, 배임죄를 침해범으로 보느냐(침해범설), 아니면 위험범으로 보느냐(위험범설)에 관한 학설상 대립이 있고, 이에 따라 기수시기에 대한 결론이 달라질 수 있다. 판례는 배임죄를 위험범으로 보면서, ‘재산상 실해 발생의 위험’이 있어야 기수에 이른다고 판시하고 있다. 나아가, 판례는 그 실해 발생의 위험은 “경제적 관점에서 재산상 손해가 발생한 것과 사실상 같다고 평가될 정도에 이르렀다고 볼 수 있을 만큼 구체적․현실적인 위험이 야기된 경우”를 의미한다고 보고 있는데, 이러한 입장은 배임죄를 침해범에 가까운 구체적 위험범으로 보고 있다고 평가받고 있다. 나아가, 판례는 배임죄의 이득액 산정과 관련하여 실제 취득한 재물 또는 재산상 이익의 실질적인 가액을 기준으로 이득액을 파악하는 해석론(소위 ‘실질가치설’)을 발전시켜나가고 있는 것으로 보인다. 특히, 대상판결은 소위 ‘실질가치설’에 입각하여, 이득액을 이 사건 옵션계약의 이행으로 실질적, 현실적으로 발생한 액수로 한정하여 산정한 것으로 보인다. 이러한 대상판결은 소위 ‘실질가치설’을 옵션계약의 특수성을 반영하여 접목시키고, 위험액 전체가 아닌 실제 손해발생액을 대상으로 하여 이득액을 산정했다는 점에서 타당하다고 생각한다. The recent transactions of derivatives such as the total return swap (TRS) have prompted a variety of social problems, including consumer damages, and the criminal liability of financial companies and employees involved in such transactions has also become controversial. Although many years have passed since the verdicts were first delivered, it is still worth reviewing the case as it covers a number of issues pertaining to a breach of trust, including business judgments, the time in which the requisite elements were fulfilled, and the calculation of gain, for various types of derivatives encompassing TRS and the option contracts. First of all, the defendants (executive members of the business group) argued that they lacked the intention to establish a breach of trust as the conclusion of the option contracts and the settlement agreements in this case were subject to business judgment. However, the ruling stated, “Notwithstanding the fact that the result of the act, which was performed to rehabilitate the entire affiliated group, was partly to serve the interests of their own, such an intention was only incidental, and once the gain or harm is found to be the primary intention, then the intention for the breach of trust cannot be denied.” Recently, the Supreme Court has set a standard to determine whether inter-affiliate subsidization in the same business group was conducted within the discretionary scope of the reasonable business judgment (Supreme Court Decision 2015Do12633 Decided November 9, 2017), but I believe that it remains difficult to deny the intent for a breach of trust based on this standard. On the other hand, there is a conflicting academic view regarding whether the breach of trust should be deemed to be a depriving offense (depriving offense theory) or an endangering offense (endangering offense theory), and the conclusion on the time in which the elements were fulfilled may differ accordingly. The precedent regards the breach of trust as an endangering offense and states that there must be a “risk of actual property damage” to satisfy the elements. Furthermore, the case views that the risk of actual harm means “when a concrete and realistic risk has arisen enough to be considered as virtually the same as property damage that has arisen from an economic perspective,” which is considered to be regarded as a breach of trust in line with a concrete endangering offense that is relatively close to the depriving offense. In addition, the case appears to be developing an analytical theory (theory of real value) that identifies the gain with the actual value of properties or property interests acquired in relation to the calculation of the gain in the breach of trust. In particular, this case calculated the “difference between the option strike price and the actual stock price” as the amount of gain with reference to the time in which the loss arose from the actual exercise of the option, rather than the time in which the risk of loss occurred (at the time of the contract conclusion) by reflecting the unique characteristics of the option contracts based on the theory of real value. This decision appears reasonable in that the theory of real value was incorporated to reflect the unique characteristics of the option contracts and strict calculations were made based on the actual amount of loss, not the amount of risk.

김지웅(Jee Woong Kim),박수형(Soo Hyung Park) 한국전산유체공학회 2008 한국전산유체공학회 학술대회논문집 Vol.2008 No.-

Flow field around helicopter involves incompressible flow near the blade root and compressible flow at the blade tip. A problem occurs for low Mach number flow due to the stiffness of the governing equations. Time-derivative preconditioning techniques have been incorporated to reduce the stiffness that occurs at low speed region. The preconditioned form of the compressible Navier-Stokes and Euler equations is used. Computations are performed for the Caradonna-Tung's hovering and non-lifting forward flight case. Computational results are in good agreement with the experimental data.

초음속 기저부 유동에서 ${\kappa}-{\varepsilon}$ 난류 모델에 대한 와점성 계수의 영향

박수형,사정환,김지웅,권장혁,김창주,Park, Soo-Hyung,Sa, Jeong-Hwan,Kim, Jee-Woong,Kwon, Jang-Hyuk,Kim, Chang-Joo 한국전산유체공학회 2008 한국전산유체공학회지 Vol.13 No.3

A supersonic base flow is computed to investigate the effect of the eddy viscosity coefficient to the linear ${\kappa}-{\varepsilon}$ turbulence models. Slight modifications to the eddy viscosity coefficient, which are based on the realizability condition, are given to the Launder-Sharma turbulence model so that present models satisfy the realizability condition. Numerical results for supersonic base flow show that turbulence models with the weaky-nonlinear eddy viscosity coefficient can lead to reasonable enhancements in the prediction of the velocity and turbulent kinetic energy profiles.
