Human epidermal keratinocytes consist of stem cells. transit amplifying cells. and postmitotic differentiating cells. Among them, stem cells playa critical role in cell renewal. wound healing. and neoplasia. However. till now, specific markers of human epidermal keratinocytes are not clearly defined. In the present study. we separated putative stem cells from other cells using fluorescence activated cell sorting (FACS). based on differences in a6-integrin and CD71 expression. (omitted)

The Interfacial friction factor for the countercurrent stratified air-wafer flow has been experimentally investigated in nearly horizontal and inclined pipes. The presence of the hydraulic jump may significantly affect both the flow pattern and the interfacial friction factor. The measured values of f$_{i}$ in nearly horizontal and two inclined pipes are of the same order of magnitude but the dependencies of the air and water velocities are slightly different.t.

This paper presents design of auxiliary circuit to reduce loss of ZVT interleaved flyback converter. The ZVT interleaved converter using the conventional auxiliary circuit has a large conduction loss due to the constant circulating current in the auxiliary circuit. The auxiliary circuit proposed in this paper, which consists of the coupled inductor and DC-link capacitor, has linearly increasing or decreasing auxiliary current. Then, the conduction loss occurring in the auxiliary circuit is reduced. The validity of the proposed auxiliary circuit is verified with the prototype of 500W.

한국형 에너지 관리 시스템 (이하 K-EMS)의 운영에 있어 현장 데이터 취득은 EMS의 기본 기능이라 할 수 있는 SCADA의 중요 요소이다. 특히 단일 통신 회선으로 구성된 K-EMS의 구조적 특성으로 인해 RTU 통신 회선의 단절은 주요 EMS Application의 운영에 영향을 미칠 수 있으므로, 예비회선 역할을 할 수 있는 데이터 Path를 확보하는 것은 이중화된 통신 회선을 갖는 것과 동일한 효과를 가질 수 있다. 이에 센터 간(Local, Remote1 and Remote2) FEP(Front End Processor)를 통해 RTU 데이터를 교환하는 데이터링크 시스템을 개발하였다.
