DOCSIS and IEEE 802.16 define the usage and element of a MAP which is uplink control message. Standards does not include the details of MAP size and the number of contention slots affecting the performance of MAC protocols for DOCSIS and IEEE 802.16. In this paper, we analyzed the performance of throughput and access delay according to the MAP size and contention slot size. Based on the analytical results, we found the optimal MAP size and the number of contention slots. We found that the protocol shows best performance when the MAP size is 2msec and the number of contention slots is 8. The simulation results can apply to the network system parameters. The simulator can be used to optimize the system parameters in cable network, BWA and WiBro. DOCSIS와 IEEE 802.16 MAC 프로토콜의 MAP 메시지는 CM의 상향 채널 데이터 전송 영역을 할당하므로 프로토콜 성능에 영향을 미치게 된다. 하지만 MAP의 구성요소와 용도에 대한 정의만 표준안에 언급이 되어있고, MAP 메시지의 크기나 MAP 메시지 내의 경쟁슬롯의 수에 대한 정의는 언급되어 있지 않다. 본 논문에서는 MAP의 크기와 경쟁슬롯의 수에 따른 프로토콜의 성능을 분석하곤 분석 결과를 바탕으로 최적의 MAP 크기와 경쟁슬롯의 수를 구하였다. 실험 결과로 MAP의 크기는 2msec이고 경쟁슬롯의 수는 8개일 때 최적의 프로토콜 성능을 보임을 알 수 있었다. 본 연구의 결과는 네트워크 시스템 파라미터로 사용할 수 있으며 실험에 사용하였던 시뮬레이터는 케이블 네트워크, BWA 및 WiBro 시스템 파라미터의 최적화에 사용할 수 있다.

Objectives : Aedes albopictus(Skuse) is known as the major vector of human arboviruses that can transmit approximately 22 virus belonging to Togaviridae, Flaviviridae, Bunyaviridae families. Recently, Aedes albopictus has been suggested to be involved in the transmission of Zika virus in several countries, including Southeast Asia. Methods : In this study, Among the military units stationed in Incheon, two coastal units were selected and two inland units were selected, we used BG sentinel trap to collection mosquitoes from June to September. Results : We have collected mosquitoes at intervals of 2 weeks and the total population of mosquito is 7,917. From among these 1,617 mosquitoes were Ae. albopictus, this accounted for 20.4% of the total mosquitoes which has greatly exceeded the national average of 23.8%. In addition, We have collected 5,460 Cx. pipiens(69.0%), 225 Anopheles spp.(2.8%), 497 Och. koreicus(6.3%), 92 Ar. subalbatus(1.2%), 20 Ae. vexans(0.3%), 2 Cx. bitaeniorhynchus, 2 Cx. orientalis, 2 Cx. tritaeniorhynchus. After we collected mosquitoes, we move immediately to the laboratory, classified mosquitoes and tested the pathogen in the way(1 pool contains maximum 50 mosquitoes) of a standard inspection method(Real-time PCR) by Korea centers for disease control and prevention. Although a total of 50 pools from the collected Ae. albopictus was performed. Flavivirus including Zika virus was not detected during study period. Moreover, malaria inspection of Anopheles spp. 30 pools were tested and that were all negative. Conclusions : According to the study, white-rooted mosquitoes living in military areas have not yet been contaminated with pathogens such as Zikavirus, Dengue fever and yellow fever, but the high habitat density indicates that there is a risk of rapid spread if these kind of diseases are infulx from abroad. Therefore, by establishing a system to monitor mosquitoes in the military, we can use it to prepare for the outbreak of foreign infectious diseases and to improve the health of soldiers and prevent the national infectious disease.

Recently, Aedes albopictus has been suggested to be involved in the transmission of Zika virus in several countries, including Southeast Asia. In this study, Among the military units stationed in Incheon, two coastal units were selected and three inland units were selected, we used BG sentinel trap to collection mosquitoes from May to October. We have collected mosquitoes at intervals of 2 weeks and the total population of mosquito is 15,959. From among these 11,406 mosquitoes were Ae. albopictus, this accounted for 71.5% of the total mosquitoes which has greatly exceeded the national average of 23.8%. After we collected mosquitoes, we move immediately to the laboratory, classified mosquitoes and tested the pathogen in the way(1 pool contains maximum 50 mosquitoes) of a standard inspection method(Real-time PCR) by Korea Centers for Disease Control and Prevention. Although a total of 257 pools from the collected Ae. albopictus was performed. Flavivirus including Zika virus was not detected during study period. According to the study, white-rooted mosquitoes living in military areas have not yet been contaminated with pathogens such as Zikavirus.
