In view of free from bluetongue (BT) in the domestic cattle population in Korea, the key of quarantine testing for BT virus (BTV) infection is detection of cattle previously exposed to the virus. The objective of this study was to estimate the probability of detecting a cattle infected with BTV using a stochastic modeling analysis of existing quarantine testing data. Three testing scenarios were considered in this study: serological testing of all animals in all imported lots (scenario 1), serological testing of a sample of cattle from all imported lots (scenario 2), and serological testing of 50% of imported lots (scenario 3). In scenario 2 and 3, it was assumed that cattle were sampled (sample size) within each lot to detect 5% of the cattle in each lot with a 95% confidence, taking into account diagnostic sensitivity of the ELISA (enzyme-linked immunosorbent assay). The model output was the total number of BTV-infected cattle and the prevalence of BTV infection in imported cattle from the US, Australia, Canada and Japan. Compared to the scenario 1, the probability of detecting a BTV-infected cattle was estimated to be 19% and 1.6% in scenario 2 and 3, respectively. Furthermore, the analyses showed a 95% confidence that BTV prevalence was less or equal to $9.7{\times}10^{-4}$ (median = $1.5{\times}10^{-5}$), indicating that, for the scenario 2 and 3 with serological testing for a sample of cattle, the risk of introducing an exotic strain of BTV into Korea through the importation of live cattle would not be acceptable.

감염병의 전파력은 무섭다. 누구를 통해, 어디에서 감염되었는지를 알아내는 것 또한 그리 쉬운 일이 아니다. 오늘날은 교통의 발달로 인해 우리나라에는 없었던 바이러스성 감염병이 유입되고 전파될 확률도 그 만큼 커져있는 상황이다. 감염병은 무엇보다 그것이 유입되기 전에 그 예방과 차단을 철저히 해야 한다. 그럼에도 유입된 경우에는 국가는 조속히 그 확산을 방지할 책무가 있다. 어떤 경우에는 감염병이 지역과 국가를 넘어 세계적 유행 상황이 되는 경우도 있다. 물론 이 경우에는 그 어느 때보다 국가 간의 협력과 세계보건기구 등의 역할이 중요해 진다. 그렇지만 이런 상황에서도 국가의 역할이 감소되는 것은 아니다. 우리 감염병예방법과 검역법은 감염위험이 있는 자 외에, 감염위험 의심자에 대해서도 격리조치를 취할 수 있다고 규정하고 있다. 격리는 더 이상의 감염을 막기 위한 매우 실효적인 수단이지만, 또한 격리의 방법과 내용 등에 비례하여 그 대상자의 자유권은 제한된다. 특히 감염병이 빠르게 유행하고 있는 상황에서는 이에 편승하여 자의적, 불합리한 격리가 발생할 수 있는 가능성도 그만큼 커진다. 이 글은 이런 시각에 기초하여 격리를 통한 공중위생 안전의 확보와 인권의 조화 문제를 생각해 보았다.

산업곤충은 부가가치를 창출하는 산업에 이용되는 곤충으로 정의된다. 일반적으로 국내 통용되고 있는 산업곤충의 대부분이 외래종이며, 인위적 유입으로 기인한 것이다. 산업곤충 시장의 급속한 확장에도 불구하고 산업곤충의 위해성평가를 위한 시스템은 적절하게 수행되지 않는다. 국내 수입곤충의 경우 농림축산검역본부에서 금지병해충으로 지정한 종에 대한 위험평가를 실시하여 외래종을 유입하고 있지만, 그 관리체계가"식물방역법" 체계에서 다루어지기 때문에 생태계 전반의 고려가 이루어지지 않는 한계가 있다. 이 문제를 해결하기 위해 국내 제도의 현황과 외국 평가체계를 살펴보았다. 분석결과, 우리나라 산업곤충 분야의 성공적인 제도적 관리를 위해서는 기본적 방향설정에 대한 합의가 필요한 것으로 분석되었고 이를 제안하였다. 또한, 위해성평가는 분류학 및 생태학적 정보의 통합 시스템이 준비되지 않는 한, 생태계를 보호하고 사전예방원칙을 따르도록 해야 하며 각 부처 간의 협력이 중요한 것으로 나타났다. 이와 함께 산업용 곤충의 위해성 평가와 위해성 심사체계의 구분이 시급한 개선사항으로 분석되었다. 위해성 평가와 위해성 심사목적, 대상, 신청기관, 위해성 평가기준의 마련을 제안하였다. 국외에서 시행되는 위해성평가체계 중에서 아일랜드의 평가체계는 경제성, 생태적 안전성, 관리적 측면 등 다양한 요소를 균형적으로 고려한 평가체계이며 사전예방주의에 입각한 것으로 분석되었다. 이는 우리나라 곤충산업의 특수성을 고려하여 산업곤충으로 인한 피해를 사전적으로 예방할 수 있는 국내 시스템으로 응용할 수 있을 것이라 사료된다.

We monitored the hitchhiker insect pests from the international vessels entering into Korea in 2021. As a result, total of 581 individuals were detected by the survey based on visual inspection with naked eye. Among them, 500 individuals were identified as 244 species of 65 families under 11 orders through the integrative taxonomic method with DNA barcoding and morphological reexamination, but the remaining 81 individuals were classified as only to the family level. Of the 244 species identified, 26 species were determined to be not-distributed species in Korea (two Orthoptera, two Hemiptera, one Megaloptera, five Coleoptera, three Hymenoptera, and 13 Lepidoptera). Among them, two species, Sagra femorata (Chrysomelidae, Coleoptera) and Dendrolimus punctatus (Lasiocampidae, Lepidoptera), were discovered as 'Regulated species' listed by Animal and Plant Quarantine Agency, South Korea. Therefore, we reported on the 26 not-distributed species in Korea and provided inanimate pathway information such as navigation routes on the vessels hitchhiking the species, state of the samples at the time of detection, identification results and original distribution for the detailed monitoring and the risk analysis on the species.

A quantitative risk assessment tool was used to provide estimates of the probability that foot-and-mouth (FMD) virus-contaminated, smuggled animal products are fed to susceptible swine in Korea. Sensitivity analyses were conducted to attempt to distinguish between parameter uncertainty and variability, using different assumptions on the effect of cooking at home, the effect of the fresh meat, and the effect of heat treatment at garbage processing facility. The median risk estimate was about 20.1% with a mean value of 27.4%. In a scenario regarding all beef and pork were considered as fresh meat the estimated median risk was 3.4%. The risk was greatly dependent on the survival parameters of the FMD virus during the cooking or heat treatment at garbage processing facility. Uncertainty about the proportion of garbage that is likely contaminated with FMD had a major positive influence on the risk, whereas conversion rate representing the size of a load had a major negative effect. This model was very useful in assessing the risk explored. However, the model also requires enhancements, such as the availability of more accurate data to verify the various assumptions considered such as FMD prevalence in a specific country, proportion of garbage which is recycled as feed, proportion of food discarded as garbage. Other factors including the effect of selection of animals for slaughter, ante- and post-mortem inspection, the domestic distribution of the smuggled products, and susceptible animals other than pigs, are need to be taken into account in the future model development.

본 연구는 규제해충(이하 해충이라 칭함) 검출 건수 상위 3개국인 말레이시아, 인도네시아, 중국의 집성재 생산업체에 대한 현장실사를 통해 해충 검출 원인을 파악하여 검역 안전성 확보를 위한 적정 집성재 생산공정을 제시하고자 수행되었다. 현장실사 결과, 수입 집성재로부터 해충 검출은 생산공정상의 문제(층재의 천연건조 또는 미흡한 열기건조, 건조 층재의 부적절한 보관, 집성재의 불완전 포장)로 확인되었다. 특히 중국은 오동나무 층재를 전적으로 천연건조하는 점을 비롯하여 생산공정이 전반적으로 가장 불량하였다. 향후 수입 집성재의 검역 안전성을 확보하기 위해서는 수입업체 스스로 해외 생산업체에 층재에 기 서식하던 해충의 구제가 가능하면서 동시에 건조 층재나 완제품인 집성재에 대한 해충 가해를 예방할 수 있는 타당한 집성재 생산공정(층재의 적절한 열기건조, 집성접착 전까지 건조 층재의 밀봉 보관, 집성재의 밀봉 포장)의 적용을 요구하여 수입 집성재로부터 해충이 검출되지 않도록 해야 할 것이다.

Background: Since 2013, the number of requests for diagnosis for horses based on neurological symptoms has increased rapidly in South Korea. The affected horses have commonly exhibited symptoms of acute seasonal hindlimb ataxia. A previous study from 2015-2016 identified Setaria digitata as the causative agent. Objectives: This study is an epidemiological investigation to find out risk factors related to the rapid increase in hindlimb ataxia of horses due to aberrant parasites in South Korea. Methods: An epidemiological investigation was conducted on 155 cohabiting horses in 41 horse ranches where the disease occurred. The surrounding environment was investigated at the disease-causing horse ranches (n = 41) and 20, randomly selected, non-infected ranches. Results: Hindlimb ataxia was confirmed in nine cohabiting horses; this was presumed to be caused by ectopic parasitism. Environments that mosquitoes inhabit, such as paddy fields within 2 km and less than 0.5 km from a river, had the greatest association with disease occurrence. Conclusions: Most horse ranches in South Korea are situated in favorable environments for mosquitoes. Moreover, the number of mosquitoes in the country has increased since 2013 due to climate change. Additional research is required; however, these data show that it is necessary to establish guidelines for the use of anthelmintic agents based on local factors in South Korea and disinfection of the environment to prevent disease outbreaks.

Milk data may be increasingly used as indicators of the protein-energy balance and actual farm feeding practices. It was related to milk production, nutritional and reproductive disorders. The purpose of this study was to investigate the relationship between level of fat, protein or milk urea nitrogen (MUN) from the first test within 35 days in milk and displaced abomasum (DA) in a large dairy herd with high yielding Holstein cows. Milk data from forty-five DA cases were compared to those from 90 healthy cows. Higher odds of DA diagnosis was found with higher 5.0% milk fat, lower 3.0% milk protein. Therefore, cows with a fat to protein ratio of>1.5 had higher risks for DA. Also, incidence rates of DA was higher in the cows which the level of MUN was lower than 12.0 mg/dl or higher than 25.0 mg/dl relative to healthy cows. These results indicate that cows diagnosed with DA were energy deficient prior to DA diagnosis. We conclude that level of fat, protein or MUN serve as a monitoring tool of protein and energy nutritional balance in early lactation cows and also as a significant predictor of risk for DA.

Non-human primate (NHP) research faces challenges due to zoonosis risk and complex veterinary management yet lacks standardized guidelines for animal care. Therefore, we developed an advanced veterinary management protocol for NHP quarantine, anesthesia, and postoperative care. Three female 4 to 5-year-old cynomolgus monkeys were anesthetized and underwent various tests, including body weight, temperature, blood tests, urinalysis, microbiological monitoring, and physical and dental examinations. Ivermectin and medicated baths were administered to eradicate ectoparasites and endoparasites, and testing was repeated 30 days later. Following quarantine, we performed computed tomography and anesthesia maintenance for mastoidectomy. To relieve pain and maintain body weight, we administered tramadol intramuscularly 4 times/day for 3 days and meloxicam subcutaneously twice daily for 14 days. Feed replacements were provided. During the 33-day quarantine period, physical examinations revealed no abnormalities indicative of infectious diseases, and no specific clinical symptoms were observed. Through a preliminary test of anesthesia time, we selected ketamine 4 mg/kg + medetomidine 50 ㎍/kg for short experiments such as computed tomography, and ketamine 8 mg/kg + medetomidine 50 ㎍/kg for intubation. Ten days after mastoidectomy, NHPs consumed 100 kcal/kg and recovered their body weight. This study offers advanced veterinary management guideline for NHP research. Such protocols can lead to more standardized and ethical practices in NHP research, thereby enhancing the quality of studies on NHPs and the translation of findings to human health and disease.

The purpose of this study is to contribute to the provision of basic data for psychological quarantine policy and counseling by examining the public perception of the "corona blue" phenomenon through analysis of social media big data. To do this, key words related to the word 'Corona Blue' were derived and analyzed using the big data analysis program 'Textom'. As a result of the analysis, words such as 'Corona 19', 'depression', 'problem' and 'overcome' were derived as key words. For the analysis results,"pride and awarenes as the public perception of Corona 19", "depression and anxiety as a group trauma as the corona blue phenomenon", "spreading a psychological quarantine culture and demanding social healing as the perception of overcoming corona Blue," and "hope for return to daily life and changes in daily life as the perception of post corona" were discussed. In conclusion, we have identified the need for active psychological support from the community By revealing that Corona Blue is a depression as a group trauma. At this time, it is confirmed that it is necessary to prioritize social healing and psychological quarantine for the main risk groups such as youth or the vulnerable, who are the socially weak.
