Nd-Fe-B 자석의 정자기장 (Static Magnetic Field)이 MC3T3-E1 세포의 alkaline phosphase (ALP) 활성도에 미치는 영향을 알아보기 위하여, MC3T3-E1 세포를 12 well 세포배양접시의 1열과 3열에 접종하고 1열과 3열의 첫째 칸 하방에 Nd-Fe-B자석을 가하여 7일, 13일, 19일, 25일간 배양한 후 세포의 ALP 활성도를 측정하였으며, 100 mm세포배양접시의 한 쪽 가장자리 하방에 Nd-Fe-B자석을 가하여 7일, 13일, 19일, 25일간 배양한 후 ALP염색을 하여 다음과 같은 결과를 얻었다. 1.정자기장을 가한 13, 19, 25일에 각각 100 mT에서는 대조군에 비해 ALP 활성도가 감소된 반면 4.6 mT와 0.5 mT에서는 대조군에 비해 ALP 활성도가 증가되었다 (P〈0.01). 2.ALP 염색에서 전체적으로는 19일까지 ALP가 증가되었다가 25일에 다소 감소되는 양상을 나타내었으며, 각 세포배양접시에서는 7일에는 뚜렷한 차이를 보이지 않았으나 13, 19, 25일에는 자석이 놓인 부위 (100 mT) 가 그 반대편(0.5 mT)에 비해 ALP가 감소되었음을 육안으로나 도립위상차현미경으로 관찰할 수 있었다. 이상의 결과 0.5 mT와 4.6 mT의 낮은 자기 장에서는 ALP 활성도가 증가되었으며 100 mT의 높은 자기장에서는 ALP활성도가 감소되어, Nd-Fe-B 자적의 정자기장이 MC3T3-E1 세포의 ALP활성도에 영향을 미쳐 골조직의 형성 및 개조에 영향을 미칠 수 있을 것으로 생각된다. Recently, the magnetic force has been considered as a method for a more efficient tooth movement. The purpose of this study was to evaluate the effects of different static magnetic fields of Nd-Fe-B magnet on MC3T3-E1 cells by measuring the alkaline phosphatase activity and observing the amount of stained alkaline phosphatase. For measuring of alkaline phosphatase activity, MC3T3-E1 cells were seeded in first and third row of 12 well culture plates. And Nd-Fe-B magnets were positioned under the first column of first and third row to apply different static magnetic fields(first column:100mT ; second column:4.6mT ; third column:0.5mT ; forth column:0.0mT) to the cells for 7, 13, 19, and 25 days. For staining of alkaline phosphatase, MC3T3-E1 cells were seeded in 100mm culture plates. And Nd-Fe-B magnets were positioned under the comer of plates to apply different static magnetic fields (magnet side:100mT, the opposite side:0.5mT) to the cells for 7, 13, 19, and 25 days. The results were as follows : 1.ALP activity was increased until day 19 in biochemical determination as well as in histochemical staining. 2.The application of higher magnetic field(100mT) suppressed ALP activity at day 13, 19, 25. On the contrary, the application of the lower magnetic field(4.6mT, 0.5mT) significantle enhanced the ALP activity. 3.Consistent with enzyme assay, histochemical staining of ALP also demonstrated that higher magnetic field(100mT) suppressed ALP activity, lower one(0.5mT) enhanced.

Development and Testing of Satellite Operation System for Korea Multipurpose Satellite-I

Mo, Hee-Sook,Lee, Ho-Jin,Lee, Seong-Pal Electronics and Telecommunications Research Instit 2000 ETRI Journal Vol.22 No.1

The Satellite Operation System (SOS) has been developed for a low earth orbiting remote sensing satellite, Korea Multipurpose Satellite-I, to monitor and control the spacecraft as well as to perform the mission operation. SOS was designed to operate on UNIX in the HP workstations. In the design of SOS, flexibility, reliability, expandability and interoperability were the main objectives. In order to achieve these objectives, a CASE tool, a database management system, consultative committee for space data systems recommendation, and a real-time distributed processing middle-ware have been integrated into the system. A database driven structure was adopted as the baseline architecture for a generic machine-independent, mission specific database. Also a logical address based inter-process communication scheme was introduced for a distributed allocation of the network resources. Specifically, a hotstandby redundancy scheme was highlighted in the design seeking for higher system reliability and uninterrupted service required in a real-time fashion during the satellite passes. Through various tests, SOS had been verified its functional, performance, and inter-face requirements. Design, implementation, and testing of the SOS for KOMPSAT-I is presented in this paper.

Virtual Line-Based Data Dissemination for Mobile Sink Groups in Wireless Sensor Networks

Hee-Sook Mo,Euisin Lee,Soochang Park,Sang-Ha Kim IEEE 2013 IEEE COMMUNICATIONS LETTERS Vol.17 No.9

<P>Mobile sink groups such as rescue teams or platoons bring about a new challenging issue for handling mobility in wireless sensor networks. Recently, a flooding-based technique has been proposed to disseminate data to a mobile sinks group. However, since it simply use flooding of data within the sink group region, it leads to high energy consumption of sensor nodes and low data delivery ratio to sinks due to the broadcast storm problem. Thus, this letter proposes a protocol called Virtual Line-based Data Dissemination (VLDD) to achieve energy-efficient and reliable data dissemination. Instead of flooding, VLDD exploits a Virtual Line Structure (VLS) for data storage within the group region. While sources store their own data on the VLS, each sink retrieves data from the VLS at its location in a time of need. Analysis and simulation results show that VLDD achieves better performance than the existing protocol.</P>
