In irradiated human lymphocytes, translocation of chromosome has been more frequently observed than dicentric chromosome. Differences in the misrepair process leading to translocation and dicentric chromosomes may explain the above observations. In order to find out whether dicentric and translocation are originated from different mechanism, the frequencies of radiation induced translocation and dicentric in lymphocytes were examined following treatment of irradiated lymphocytes with two DNA repair inhibitors, 3AB for inhibition of poly(ADP-ribose) synthesis and Ara C for inhibition of DNA-polymerase $\alpha$. Ara C potentiated the frequencies of radiation induced dicentric and translocation. 3AB also potentiated the frequencies of radiation induced dicentric, but not translocation. These results suggest the potential differences in the mechanisms in the formation of translocation and dicentric chromosomes.

Formation of asbestos bodies in various organs of mouse in course of time after intraperitoneal injection of three types of asbestoses was studied. Asbestos bodies as well as asbestos fibers were found both in intrapleural organs such as lung and heart and intraperitoneal organs after intraperitoneal injection of asbestos fiber this suggested the possibility that asbestos fiber could migrate to the whole body. When asbestos was injected intrapleurally asbestos fiber was found in the lung 15 days after injection but asbestos body was not found till 30 days after injection. The process of asbestos body formation was described.

압축성 초탄성 평판의 순수굽힘에 대한 비선형 변형해석의 수학적 정해가 본 논문에 구해져 있다. 이차원 평면 변형도 상태가 해석을 위하여 가정되었으며, 비선형 순수굽힘 변형해석결과는 고전적인 선형 순수굽힘 변형해석결과와 비교되었다. 고전적인 선형굽힘 결과와는 다르게 비선형 순수굽힘 상태에서는 반경방향응력은 영이 아니며 또한 각방향응력도 선형 상태가 아닌 것으로 규명되었다.

This paper presents a design and implementation of 10gigabit ethernet frame multiplexer/demultiplexer. In this paper, we discuss gigabit and 10 gigabit ethernet standard interfaces(GMII/XGMII) and we propose multiple gigabit ethernet frame multiplexing/demultiplexing scheme to handle 10gigabit ethernet frame instead of using 10gigabit network processor. And then 10gigabit ethernet frame MUX/DMUX is designed, verified and implemented using FPGA.

Due to the explosive popularization of the Internet, it has been researched for many mobile terminals how to receive various multimedia information. Especially, it has been considered that a mobile terminal is serviced with multimedia information through a inherent IP address. In this paper we have proposed the Handover Signaling Method and analyzed the Handover delay time of this proposed method in wireless section. This proposed method is appropriate to Broadband systems with Mobile IP. We have simulated Handover delay time with respect to the distance between a terminal and base stations
