Epithelial-myoepithelial carcinoma is a rate low-grade malignant salivary neoplasm that usually occurs in the parotid gland but can also arise in minor salivary glands. We report a case of a primary epithelial-myoepithelial carcinoma of the lung neoplasm. The patient was 48-year-old women who presented with dry cough of 1 month duration. A right middle lobe endobronchial lesion was identified bronchoscopically. The bilobectomy of RML & RLL was performed, the pathologic result was epithelial-myoepithelial carcinoma.

최근에 계산금융 분야에서 복잡한 수식을 이용한 연산이 증가하고 있다. 그리고 계산금융 분야에서 몬테카를로 시뮬레이션은 대표적인 계산방법 중에 하나이다. 그러나 몬테카를로 시뮬레이션은 많은 반복연산을 수행하므로 연산시간이 오래 걸리는 문제점이 있다. 이러한 문제점을 해결하기 위하여 본 논문에서는 몬테카를로 시뮬레이션과 스프레드시트를 병렬로 처리하였다. 또한 실험을 통하여 병렬 스프레드시트의 계산 노드가 증가함에 따라 파생상품의 계산 시간이 단축되는 것을 보였다.

The dc link voltage in a single-phase PV system has necessarily twice component of fundamental wave. It makes high THD in the grid current, and according to the problem, power quality is lower. This paper proposes the new method for removing ripple voltage. The performance was verified through computer simulation using MATLAB.

Recently most companies require various type of energy sources, in order to be more energy efficient in their plant due to the increasing current oil price. So, the multi-national companies are shaping ideas how to reduce energy costs and use substitute energy. The purpose of this study Is to attempt to save energy by making more valuable high pressure steam through TVR(Thermal Vapor Recompressor) from the surplus low pressure steam of HRB(Heat Recovery Boiler) in sulfuric acid plant.
