사물인터넷은 기존의 여러 ICT기술과 유, 무선 장비의 네트워크 및 다양한 통신 기술들이 적용된 것을 의미한다. 최근 다양한 사물 인터넷에 대한 발전은 경량화, 소형화 되어가며 OSHW(Open Source HardWare)을 기반으로 점차 다양화 되었다. 이에 따라 사물인터넷 다양한 디바이스와 펌웨어, 암호학에 대한 연구는 활발하게 진행되고 있다. 하지만 특정 하드웨어의 센서 디바이스에 대한 연구는 부족하다. 본 논문에서는 OSHW 중 하나인 AVR기반의 아두이노 개발도구에 대한 임시 파일에 대해 분석하고 메모리 초기화 방법에 대해 제안한다. 또한 임시파일을 이용한 메모리 초기화 방법을 이용하여 사용자정보와 메모리 공격에 대한 데이터 유출을 방지할 수 있다.

To investigate the effects if ionizing radiation on the hepatic tissue, various doses of X-ray(1,000 rads, 1,400 rads, 1,800 rads) were irradiated to the left upper quadrant of abdomen of rats(source-skin distance, 1m;field size 23X23mm), by means of linear accelerator. At 1, 2, 3, and 4 weeks after single exposure to each dose, histological(hematoxylin-eosin) and histochemical(PAS, trichrome, and reticulin) stains for the left lobe of the liver. Then inflammatory cell index, fibrosis index, nuclear index, and vascular index were estimated in the hepatic tissue specimens. The results were as follows. 1. dilatation and congestion of the hepatic sinusoids were the most prominent at 1 week after 1,400 and 1,800 rads-irradiated liver tissue. 2. Inflammatory cell indices were increased in all irradiated livers, in comparison with that of control. The increase was most prominent in 1,800 rads-irradiated group. 3. Fibrosis indices were progressively increased from 2 weeks after irradiation, but withour dose-dependency. 4. Nuclear indices were begun to increase at 2 weeks after 1,400 and 1,800 rads-irradiation. The increase was prominent at 3 and 4 weeks after irradiation. 5. Vascular indices were not changed during 3 weeks after irradiation, and the gradual increasing-pattern was noted. From these results, one could finds out changes of the hepatic tissue exposed to ionizing radiation are dilatation and congestion of sinusoids as an early response, and increased fibrosis and nuclear poikilosis as subsequent resoponses. The early changes might be a part of general inflammatory reaction and autoimmune reaction resulting from early tissue damage, and the subsequent changes are secondary to vascular injury induced by radiation.
