아프리카 돼지 열병의 세계적인 확산과 함께 가축전염병에 대한 관심이 증가하고 있다. 가축관련 운송차량은 가축전염병 확산의 주요 원인으로 제기되고 있으나 국내에서는 가축관련 운송차량의 이동성과 관련한 실증적인 방역절차와 기준이 마련되지 않고 있는 실정이다. 이에 본 연구는 국가가축방역시스템의 축산시설 방문이력 데이터와 한국교통안전공단의 DTG(Digital Tachograph) 데이터를 활용하여 가축관련 운송차량이 이용한 도로이용정보를 추출하고, 각 차량의 링크별 점유시간을 집계하여 노출도 지표로 제시하였다. 총 274,519행의 가축관련 운송차량의 통행궤적이 추출되었으며 링크별, 존별 노출도를 정량적으로 도출하였다. 본 연구를 통해 가축관련 운송차량의 사전 모니터링 및 사후 방역방침 수립이 가능할 것으로 기대된다.

아프리카 돼지열병, 구제역 등 가축전염병 유행과 관련된 기존의 연구 결과에서 가축전염병 확산의 주요 원인으로 축산 관련 차량 통행을 지목하는 경우가 많다. 이에 본 연구는 경기도 내 축산시설의 차량 방문이력 데이터와 화물차량의 디지털 운행기록계 데이터를 결합하여 각 읍면동의 주중 축산 화물차량 OD 통행량을 구한 후, 이에 기반한 가축전염병 확산 예측모형을 개발하였다. 모형은 2015년 1~2월 당시 주차별 구제역 발병기록을 이용하여 훈련되었으며, 긍정적 시나리오 기준으로 검증용 감염 표본 13개의 감염을 모두 예측해내는 데에 성공했다.

Various infectious diseases have threatened swine industries in Korea. One of the major risk factors of disease spread is livestock transport vehicle. For this reason, all abattoirs are required by law to have vehicle washing and disinfection facilities. However, detailed guidelines for cleaning and disinfection procedures were not provided. So in this study, assessment by visual observation was conducted to evaluate how well the cleaning and disinfection procedures of livestock transport vehicles have been performed in four different abattoirs in Jeonbuk, Korea. The observation included length of car washing time, the number of washing bay, type of washperson, type of disinfectant application, length of disinfection time, and compliance of driver's hygienic procedure. Every vehicle in all abattoirs conducted washing and disinfection procedure. However, there were procedural differences for each abattoirs and defects in the washing and disinfection procedures. In addition to that, the compliance of driver's hygienic procedure was not sufficient. Hence, detailed manuals on washing and disinfection procedures for involved people are required and it is necessary to establish an inspection and evaluation system.

최근 다양한 사회 경제 이슈가 사회적인 화두로 떠오르고 있으며, 지역 경제 상황을 빠르게 판단하고 정책을 수립하기 위한 경기종합지수의 중요성이 대두되고 있다. 이에 따라 해외 연구자들은 지역 경제활동과 밀접하게 연관된 실시간성 교통 빅데이터를 이용하여 빠른 경제 상황 진단과 맞춤형 정책 방향의 수립을 고려하고 있다. 본 연구의 주요 목적은 울산광역시를 기종점으로 하는 TCS 데이터를 여객·화물통행, 단거리·장거리통행으로 구분하고, 각각의 통행량을 이용하여 지역경기진단이 가능한 경기종합지수들을 선정한 후 각 지수들의 경기변동 특징인 선행, 동행, 후행성을 교차 상관함수(Cross-Correlation Functions) 분석을 통하여 정의하는데 있다. 연구 결과로부터 TCS 교통량의 추이와 상관관계가 높은 경기 종합지수들은 서비스업 생산지수, 도매 및 소매업, 숙박 및 음식점업 등으로 나타났다. 이 중 화물, 여객, 단거리 목적 통행은 도매 및 소매업, 숙박 및 음식점업에 대해 선행성을 가지는 것으로 도출되었다.

The livestock infections had been happened seasonally, but they have gradually changed to be irrelevant to seasons and have an aspect to rapidly spread after outbreak. Especially in Korea, proactive disinfection measures are very important because the livestock farms are located densely so high as to accelerate the spread of disease between farms. livestock disease outbreaks like HPAI and FMD occurred with high probability due to vehicles visiting the farms, this study is to evaluate the efficiency of livestock vehicle disinfection systems by investigating the disinfectant coverage according to the type of vehicle disinfection system and the type of vehicle quantitatively. In field experiments, water-sensitive papers (WSPs) were attached to 21 locations on the surface of four vehicles (sedan, SUV, truck, and feed transport), respectively, and exposed to disinfectants while the vehicle was sprayed in two vehicle disinfection systems (tunnel type and simplified type). The WSPs were scanned and image-processed to calculate the disinfectant coverage. The results showed that the tunnel-type vehicle disinfection system had a better disinfection performance with an average coverage of 90.27% for all vehicles compared to 32.62% of the simplified type system. The problem of the simplified system was a wide coefficient of variation (1.05-1.31) of the disinfectant coverage between 21 locations indicating a need for further improvement of nozzle location and arrangement.

Most of livestock houses are concentrated in certain area with mass rearing system resulting in rapid spread of infectious diseases such as HPAI (highly pathogenic avian influenza). The livestock-related vehicles which frequently travel between farms could be a major factor for disease spread by means of transmission of airborne aerosol including pathogens. This study was focused on the quantitative measurement of aerosol concentration by field experiment while vehicles were passing through the road. The TSP (total suspended particle) and PM10 (particle matter) were measured using air sampler with teflon filter installed downward the road with consideration of weather forecast and the direction of road. And aerosol spectrometer and video recorders were also used to measure the real-time distribution of aerosol concentration by its size. The results showed that PM2.5 was not considerable for transmission of airborne aerosol from the livestock-related vehicle. The mass generated from the road during the vehicle movement was measured and calculated to 241.4 ${\mu}g/m^3$ by means of the difference between TSP and PM2.5. The dispersion distance was predicted by 79.6 m from the trend curve.
