감염 질병의 심각한 확산으로 인해 방역의 중요성이 점점 커지고 있다. 또한 방역 이슈가 없는 언택트 산업에 대한 관심도 늘어나고 있다. 본 논문에서는 등록된 사용자의 얼굴을 인식함으로써 비접촉 방식으로 출입을 통제하는 비용 효율적인 라즈베리파이 기반 도어락 시스템을 설계하고 개발한다. 우선, OpenCV의 Haar-based cascade를 사용하여 매우 단순한 특징들을 조합하여 객체를 찾고, 얼굴 인식을 진행한다. 그리고 LBPH (Local Binary Pattern Histogram)을 사용하여 이미지의 질감을 이진화하여 특징을 찾아낸다. 라즈베리파이 3B+ 보드, 초음파 센서, 카메라 모듈, 모터 등으로 언택트 도어락 하드웨어를 구현하고, 얼굴 인식 및 매칭 알고리즘을 포함한 소프트웨어를 기반으로 약 500장의 이미지 데이터를 학습시켜 실험한 결과, 최대 85.7%의 인식률을 보이며 사용자를 구분하는 성능을 검증할 수 있었다. 또한, Haar-cascade 알고리즘 성능의 광원에 대한 영향성을 파악하여 그 개선 가능성을 살펴보았다.

This thesis is a study on the change and the process of the development of the hygiene administration during the period of modernization of our nation which promoted by the open door policy of our country chiefly under the pressure of the foreign countries. During that period Korea had reorganized the old political system radically and introduced the western medical system. Through the close study of literature concerning the system of the hygiene administration, the laws of health and hygiene, the environmental sanitation organizations and their practical activities the author obtained the conclusions as following 1. The government passed around 40 laws of health and hygiene from the time when the bureau of hygiene was founded in 1894 to the annex of Korea to Japan. Most of the laws were believed to be established by the enforecement of Japanese government. When the epidemics were prevailing, a decree for the prevention of the epidemics was proclaimed by the Japanese president of the headquarters of national police. It is shown well that the sovereignty of Korea had been deprived. 2. After the armex of Korea to Japan, the hygiene police and the general police belonging to the bureau of national police shared the tasks of health and hygiene. This was a temporary system which had existed just during the colonial period. As for the water-supply which is the most important facility among the various environmental hygiene facilities, the rate of supply was remarkably high in Japanese rather than in Korean. 3. During the period of American military administration, it is notable that the division of hygiene in the bureau of national police was replaced by the bureau of hygiene. This period is regarded as the turning point when hygiene administration was operated by means of education along with the introuction of American system of public health. 4. Ever since the foundation of the republic government, the laws of health and hygiene which had been established during the colonial period have been put into operation without rriuch change except several regulations concerning food.

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.

본 연구는 우리나라의 구재역 문제가 심각한 사회문제로 대두되면서 현재의 방역대 설정에 대한 문제점을 분석하여 사전 조치를 통한 피해를 최소화하기 위하여 수행하였다. 이를 위하여 구제역 발생 현황을 분석하고, 전국 국도의 도로망도와 행정구역 경계 등의 자료를 이용하여 도로를 통해 차량으로 전염되는 것을 가정한 후 네트워크 분석을 수행하였다. 이와 같이 분석된 결과를 이용하여 전파시간을 산정하고, 그 결과를 도로 직선거리 및 도로 실거리로 구분하여 직선 이동속도 및 도로 실거리 이동속도를 국도별 및 행정구역별로 산출하여 현재의 구제역 방역대 설정방법에 대한 문제점을 분석하였다. 따라서, 본 연구는 구제역 발생지역을 중심으로 전파속도를 산출한 결과 평균 직선 전파속도는 53.9km/day, 평균 도로 실거리 전파속도는 71.1km/day로 분석되어 기존 방역대 설정에 문제가 있었음을 알 수 있었다.

Control and prevention of foot and mouth disease (FMD) by vaccination remains unsatisfactory in endemic countries. Indeed, consistent and new FMD epidemics in previously disease-free countries have precipitated the need for a worldwide control strategy. Outbreaks in vaccinated animals require that a new and safe vaccine be developed against foot and mouth virus (FMDV). FMDV can be eradicated worldwide based on previous scientific information about its spread using existing and modern control strategies.

This study was attempted to investigate the properties of brucellosis in Korean indigenous cattle at the Yeongwol and Pyeongchang county. Brucella spp was differentiated and identified from cotyledons, amniotic fluids and supramammary lymph nodes which confirmed with clinical, serological, epidemiological evidences (69 cases) from January to June, 2004. Isolation frequency of this causative agent from supramammary lymph nodes, cotyledons and amniotic fluids from 38 pregnant Korean indigenous cattle were $39.1\%,\;87.5\%,\;and\;63.2\%$, respectively, and finally confirmed with Brucella abortus biotype 1 through biochemical and serological test. A Brucella specific DNA with 711bp band was detected by PCR assay using BCSP primer. The two cases were definite epidemiological evidences that infected Korean indigenous cattle acrossed the border to Yeongwol and Pyeongchang from near two provinces. Effective prevention programs are urgently needed for further spreading this epidemics.

The impact of the next influenza pandemic is difficult to predict. It is dependent on how virulent the virus is, how rapidly it spreads from population to population, and the effectiveness of prevention and response efforts. Despite the uncertainty about the magnitude of the next pandemic, estimates of the health and economic impact remain important to aid public health policy decisions and guide pandemic planning for health and emergency sectors. Planning ahead in preparation for an influenza pandemic, with its potentially very high morbidity and mortality rates, is essential for hospital administrators and public health officials. The estimat ion of pandemic impact is based on the previous pandemics- we had experienced at least 3 pandemics in 20th century. But the epidemiologi cal characteristics - ie, start season, the impact of 1st wave, pathogenicity and virulence of the viruses and the primary victims of population were quite different from one another. I reviewed methodology for estimation and modelling of pandemic impact and described some nations's results using them in their national preparedness plans. And then I showed the estimates of pandemic influenza impact in Korea with FluSurge and FluAid. And, I described the results of pandemic modelling with parameters of 1918 pandemic for the shake of education and training of the first-line responder health officials to the epidemics. In preparing influenza pandemics, the simulation and modelling are the keys to reduce the uncertainty of the future and to make proper policies to manage and control the pandemics.

Hydatid worms, hosted by humans and animals, impose serious human health risk and cause significant livestock production loss. To better understand the disease infection status in Xinjiang, China, we investigated the disease epidemics in 4 livestock animals, i.e., cattle, sheep (both sheep and goat), camels, and horses, slaughtered at the abattoirs in Urumqi, Yining, Tacheng, and Altay areas. The results showed that the animals were infected at different rates, in the order of sheep (9.8%), cattle (8.4%), camels (6.8%), and horses (4.3%). The infection rates were found to be different between the abattoirs in various regions even for the same animals. For sheep, the rates increased significantly as the animals grew older. It was 1.9% before 1 year of age and increased to 8.2% in the age of 1-2 years, and further increased to 12.3% when the animals were 3-4 years old, and reached 17.2% when they were 5-6 year old. Sheep older than 6 years had an infection rate of 19.5%. This study demonstrates that the 4 livestock animals in the pastoral areas in Xinjiang were infected by the parasites to various extend. This study is the first systematic investigation of the hydatid worms in various livestock animals in Xinjiang, China, which provides epidemiological information about the infection of hydatid worms in livestock, and is valuable in developing strategies for prevention and control of the hydatid disease.
