인문학은 인간에 대한 깊은 성찰과 세계에 대한 폭넓은 조망에서 잉태한다. 이런 인문학 교육은 인문대학만이 아니라 전반적인 의료교육 현장에 접목되어야 한다. 따라서 인문학 역시 현실을 도외시한 언어유희가 아니라 현실속의 사회 문화적 통로를 접근하는 방식으로 도입되어야 한다. 인문학적 성찰은 전문가만의 소유물이 아니다. 특히 의료인문학적 성찰은 죽은 몸이 아니라 살아 있는 몸을 다루는 임상행위의 전제이다. 이렇게 살아 있는 생명의 몸을 다루는 의학 부문에서 과학적 설명의 적용범위와 그 실현가능성은 아직 충족되고 있지 않다. 이는 과학탐구 대상으로서의 톰과 증상과 치료의 대상으로서의 구체적인 의학적 몸 사이의 간극이 있음을 무시할 수 없다는 점이다. 인문학적으로는 설명 장르의 몸에서 제외된 이해 장르의 몸이 다시 조명되어야 한다. 정확히 말하면 설명 장르와 이해 장르가 통합되어야 한다는 뜻이기도 하다. 이러한 인문학적 반성이란 추상적 이론으로 그쳐서는 안 되며, 의학과 의료 현실에 어떻게 실천적으로 적용가능한지를 질문하는 일이다. 이 논문에서는 그 적용사례로서 증거중심의학(EBM)과 문제기반학습(PBL)를 다루었다.

In micro-EBM, it is well blown that RC circuit is suitable for discharge circuit because of its low pulse width and relatively high peak current. To increase machining speed without changing unit discharge energy, charge resistance should be decreased. But, if very low, continuous (or normal) arc discharge occurs, then increases electrode wear and reduces machining speed remarkably. In this paper, RC circuit with transistor is used to micro-EDM. Experimental results show that RC circuit with transistor can cut off continuous (or normal) arc discharge effectively if duty factor and switching period of transistor are set up optimally. Through experiments with varying charge resistance, it can be known that RC circuit with transistor has about two times faster machining speed than that of RC circuit. Especially, it has prominent rise-effect of machining speed in low unit discharge energy, so that a high-quality and high-speed micro-EDM can be realized through RC circuit with transistor.

Purpose: Ovarian cysts are fluid-filled sacs or pockets within or on the surface of an ovary. Most cysts present little or no discomfort and are noncancerous and harmless. So non-surgical treatments with herbal medicine or acupuncture and moxa therapy are important and suitable in this pathology. But there are few RCT articles about ovarian cyst in Korean Medicine(KM) clinical and research field. Methods: To review treatment method and other research tendency about ovarian cyst in journals related with KM and Traditional Chinese Medicine(TCM) through web-searching. Searching was done through web site #http://omis.ksucc.ac.kr# and pub-med(http://www.ncbi.nlm.nih.gov/sites/entrez) with key words #ovarian cyst#, #TCM#, #herb#, #CAM#, and #acupuncture#. Results: Seven articles were searched in journals related with KM, then six of them were simple case report and the other one was about diagnosis for ovarian cyst and another gynecologic disease such as uterine myoma and infertility through the iris diagnosis. And two articles were searched in journals related with TCM, then one of them was simple case report but the other is RCT article. Conclusion: KM and TCM therapies have some beneficial effect to resolve cyst, but objective power as a evidence is weak in the viewpoint of EBM. So continuous clinical trials such as RCT and multi center trials are needed.

This paper reports briefly on the computational results of a turbulent Rayleigh-Benard convection with the elliptic-blending second-moment closure (EBM). The primary emphasis of the study is placed on an investigation of accuracy and numerical stability of the elliptic-blending second-moment closure for the turbulent Rayleigh-Benard convection. The turbulent heat fluxes in this study are treated by the algebraic flux model with the temperature variance and molecular dissipation rate of turbulent heat flux. The model is applied to the prediction of the turbulent Rayleigh-Benard convection for Rayleigh numbers ranging from Ra=$2{\times}10^6$ to Ra=$10^9$ and the computed results are compared with the previous experimental correlations, T-RANS and LES results. The predicted cell-averaged Nusselt number follows the correlation by Peng et al.(2006) (Nu=$0.162Ra^{0.286}$) in the 'soft' convective turbulence region ($2{\times}10^6{\leq}Ra{\leq}4{\times}10^7$) and it follows the experimental correlation by Niemela et al. (2000) (N=$0.124Ra^{0.309}$) in the 'hard' convective turbulence region ($10^8{\leq}Ra{\leq}10^9$) within 5% accuracy. This results show that the elliptic-blending second-moment closure with an algebraic flux model predicts very accurately the Rayleigh-Benard convection.
