본 연구는 야생동물위치추적기(WT-300, GPS-Mobile Phone Based Telemetry, KoEco)를 이용하여 도심지역과 농촌지역에서 월동하는 흰뺨검둥오리의 서식지 이용을 파악하여 국내 수조류 서식지 보호∙관리의 기초자료로 활용하 고자 수행하였다. 연구지역은 경기도 안성시의 도심하천인 안성천과 해남의 산수저수지로 지역별로 각각 흰뺨검둥오리 5개체에 위치추적기를 부착하였다. 흰뺨검둥오리의 행동권 분석은 GIS용 SHP 파일과 ArcGIS 9.x Animal Movement Extension을 이용하였으며, 커널밀도측정법(Kernel Density Estimation : KDE)과 최소볼록다각형법(Minimum Convex Polygon Method : MCP)을 이용하여 분석하였다. 흰뺨검둥오리의 행동권은 최소볼록다각형법에 의하면 안성은 250.8 ㎢(SD=195.3, n=5), 해남은 89.1㎢(SD=69.6, n=5)이였다. 커널밀도측정법에 의한 50% 이용면적은 안성은 21.8㎢ (SD=26.9, n=5), 해남은 3.5㎢(SD=2.2 n=5)로 해남지역에서 좁은 행동권을 보였다. 흰뺨검둥오리의 서식지 이용을 보면 안성과 해남지역 모두 내륙습지와 논을 주로 이용하였다. 하지만 해남에서는 주간에, 안성에서는 야간에 논 이용률 이 높았으며, 월동후기로 갈수록 해남에서는 주간에, 안성에서는 야간에 논 이용률이 증가하는 경향을 보였다.
This study describes the national program of year-round surveillance and monitoring for avian influenza (AI). The validity of the epidemiologically-based surveillance scheme was assessed. Korea’s current surveillance program is aimed at detecting subclinical infection of either the highly pathogenic avian influenza (HPAI) virus or the low pathogenic avian influenza virus, types H5 and H7, both of which carry risk of converting to HPAI. The current AI surveillance program has demonstrated that implementing a surveillance strategy is plausible. Farmer and livestock related professional support is the critical step of specimen collection to discover hidden infection. Early detection of AI virus infection can achieve best by the combined efforts of farmers, animal health authorities, and other related industries.
Foot-and-mouth disease (FMD) has great potential for causing huge economic loss and was the first disease identified by the World Organisation for Animal Health (OIE) in its official list of free countries and zones. This study examined the governmental expenditures for five FMD epidemics that occurred in the Republic of Korea between 2000 and 2011. The costs of an epidemic ranged from 26 billion Korean won (KRW, approximately 23.6 million US dollars, ) to a maximum of 2,044 billion KRW (US 1.9 billion). For two epidemics in which vaccinations were implemented, the costs were higher than those epidemics without vaccination. The mean cost for an outbreak ranged from 0.5 billion KRW (US 4.5 million) for the 2010/2011 epidemic to 18.2 billion KRW (US 16.5 million) for the 2000 epidemic. Mean costs per infected premises were 7.0 billion KRW for cattle farms (95% CI: 4.72∼9.28), 1.38 billion KRW for pig farms (0.88∼1.87), 0.11 billion KRW for deer farms (0.08∼0.14), and 0.10 billion KRW for goat farms (0.07∼0.13). The highest cost for an outbreak in cattle seemed associated with the number of outbreak cattle farms in two epidemics in which vaccination was implemented.
