Establishing veterinary graduation competencies and its impact on veterinary medical education in Korea.

Competencies are defined as an observable and assessable set of knowledge, skills, and attitudes. Graduation competencies, which are more comprehensive, refer to the required abilities of students to perform on-site work immediately after graduation. As graduation competencies set the goal of education, various countries and institutions have introduced them for new veterinary graduates. The Korean Association of Veterinary Medical Colleges has recently established such competencies to standardize veterinary education and enhance quality levels thereof. The purpose of this study is to describe the process of establishing graduation competencies as well as their implication for veterinary education in Korea. Graduation competencies for veterinary education in Korea comprise 5 domains (animal health care and disease management, one health expertise, communication and collaboration, research and learning, and veterinary professionalism). These are further divided into 11 core competencies, and 33 achievement standards, which were carefully chosen from previous case analyses and nation-wide surveys. Currently, graduation competencies are used as a standard for setting clear educational purposes for both instructors and students. Establishing these competencies further initiated the development of detailed learning outcomes, and of a list of basic veterinary clinical performances and skills, which is useful for assessing knowledge and skills. The establishment of graduation competencies is expected to contribute to the continuous development of Korean veterinary education in many ways. These include curriculum standardization and licensing examination reform, which will eventually improve the competencies of new veterinary graduates.

Stressors Predicting Depression, Anxiety, and Stress in Korean Veterinary Students.

Psychological distress has a negative impact on professional development in health care professions. In this article, we measured the prevalence of students' depression, anxiety, and stress using the DASS-21 questionnaire in 10 veterinary colleges in Korea to investigate the stressors that contribute to these forms of psychological distress. The prevalence of academic and relationship types of stressors were higher than others. The proportion of students above a severe level of depression, anxiety, and stress on the DASS-21 scales was 30.9, 35.8, and 43.2%, respectively. The DASS-21 scores mediated the relationship between the perceived frequency of stressors and the respondents' satisfaction with their education and career. Statistical analysis revealed that female and pre-clinical students are more vulnerable to depression, anxiety, and stress. The findings of the article indicate the gravity of Korean veterinary students' mental and psychological state, emphasizing the importance of comprehensive management of students' mental health.

Traumatic Stress of Frontline Workers in Culling Livestock Animals in South Korea.

The last decade brought several devastating outbreaks of foot and mouth disease and avian influenza in South Korea, which had been handled through preventive culling, despite the controversy surrounding its efficiency and ethical considerations. Notably, the lack of regulations on culling processes has exposed the workers to extremely harsh working conditions. This study investigates the effect of culling jobs on the mental health of the frontline workers, based on 200 samples collected through a web-based survey conducted on participants with experience of culling tasks. Culling was found to have a powerful negative effect on the workers' mental health, including high depression rates. Of those surveyed, 83.7% answered that the working conditions were intense, and 74.5% showed scores above the cutoff point for post-traumatic stress disorder (PTSD). A regression analysis revealed that individual's attitudes toward animals mediated the effect of culling experience on PTSD symptoms. However, mental health care for the workers has been insufficient: 70.2% of the respondents were willing to get mental treatment to deal with the distress they underwent from culling. We conclude that engagement in culling has a detrimental effect on the workers' mental health, and that they should be provided with systematic mental health care.

An Analysis of Veterinary Practitioners' Intention to Intervene in Animal Abuse Cases in South Korea.

Due to their professional abilities, veterinarians have a duty to reduce animal abuse. Therefore, it is crucial to understand their attitude and behavior on encountering animal abuse cases. We analyzed the responses from completed questionnaires (n = 593) filled by small and large animal practitioners in South Korea. The majority (n = 513, 86.5%) of the respondents witnessed suspected animal abuse cases in their practice. The female participants, small animal practitioners, and younger veterinarians tended to report animal abuse cases more frequently. Based on a hierarchical regression model, moral obligation was the statistically significant predictor of intention toward counseling owners (F = 22.089, R2 = 0.232, p < 0.001) while "pro-animal" attitudes, belief in the "link" between animal and human crimes, and moral and legal obligation were significant predictors of intention to report (F = 22.877, R2 = 0.239, p < 0.001). The most frequent barrier in reporting abuse cases was the difficulty in assuring animal safety afterwards. Our findings revealed that individual characteristics (sex, age, practice type, pro-animal attitude) affect veterinarian sensitivity in recognizing animal abuse. Participants lacked self-efficiency in managing animal abuse cases. Therefore, strengthening professionalism and training veterinarians in identifying nonaccidental injuries caused by abuse are recommended to motivate them to intervene in abuse cases.

Active learning through discussion: ICAP framework for education in health professions.

BACKGROUND: The ICAP framework based on cognitive science posits four modes of cognitive engagement: Interactive, Constructive, Active, and Passive. Focusing on the wide applicability of discussion as interactive engagement in medical education, we investigated the effect of discussion when it was preceded by self-study and further investigated the effect of generating questions before discussions. METHODS: This study was conducted in the second semester of 2018 and was participated in by 129 students majoring in health professions, including medicine, dentistry, veterinary medicine, and nursing. The students were assigned to four different trial groups and were asked to fill out a Subjective Mental Effort Questionnaire after completing each session. Their performance in posttest scores was analyzed using Bonferroni test, and mental effort was analyzed using mediation analysis. RESULTS: These results indicated that the self-study and question group had the highest performance and that the lecture and summary group had the lowest performance when comparing the total score. Using the analysis of mental effort, it was confirmed that the relationship between different study conditions and post-test performance was mediated by mental effort during test. CONCLUSIONS: Our findings support the ICAP framework and provide practical implications for medical education, representing the fact that students learn more when they are involved in active learning activities, such as self-study and question generation, prior to discussions.

Disentangling the link between supplemental feeding, population density, and the prevalence of pathogens in urban stray cats.

BACKGROUND: Supplemental feeding of free-roaming animals, including wildlife and feral or stray animals, is well known to have a substantial impact on various aspects of animal ecology including habitat use, activity patterns, and host-pathogen interactions. Among them, an increased population density (PD) of animals receiving supplemental food raises concerns regarding the transmission of pathogens in these host populations. The primary aim of this study was to investigate how supplemental feeding is associated with host PD and prevalence of pathogens with different transmission modes in urban stray cats. We hypothesized that supplemental feeding would be positively associated with host PD and the prevalence of pathogens with density-dependent transmission modes compared with pathogens with transmission modes that are considered relatively density-independent. METHODS: This study was conducted in six districts in Seoul, Republic of Korea which were selected based on different degrees of supplemental feeding and cat caretaker activity (CCA). The PD of stray cats was estimated by mark-recapture surveys. Stray cat blood samples (N = 302) were collected from stray cats by local animal hospitals from each district performing the trap-neuter-release which tested for eight pathogens with different transmission modes (feline immunodeficiency virus, feline leukemia virus (FeLV), feline panleukopenia virus, feline calicivirus, feline herpesvirus-1, Bartonella henselae, hemoplasma, and Toxoplasma gondii) with molecular or serological assays. Associations between the prevalence of each pathogen and PD, CCA, and sex of cats were statistically analyzed. RESULTS: In contrast to initial predictions, the cat PD was generally higher in low CCA districts. The prevalence of (FeLV), which is transmitted through direct contact, was significantly higher in areas with a high CCA, conforming to our hypothesis. On the other hand, the prevalence of feline parvovirus, which can be spread by environmental transmission, was higher in low CCA districts. The remaining six pathogens did not show any association with the CCA; however, they had a unique association with the PD or the sex of the stray cats. DISCUSSION: Our findings suggest that in addition to influencing the PD, supplemental feeding may affect the prevalence of pathogens in urban animals by mechanisms such as increased aggregation and/or altered foraging strategies, with different consequences depending on the transmission mode of each pathogen.

Ensuring reproducibility and ethics in animal experiments reporting in Korea using the ARRIVE guideline.

The aim of this study is to evaluate the reporting quality of animal experiments in Korea using the Animals in Research: Reporting In Vivo Experiments (ARRIVE) guideline developed in 2010 to overcome the reproducibility problem and to encourage compliance with replacement, refinement and reduction of animals in research (3R's principle). We reviewed 50 papers published by a Korean research group from 2013 to 2016 and scored the conformity with the 20-items ARRIVE guideline. The median conformity score was 39.50%. For more precise evaluation, the 20 items were subdivided into 57 sub-items. Among the sub-items, status of experimental animals, housing and husbandry were described under the average level. Microenvironment sub-items, such as enrichment, bedding material, cage type, number of companions, scored under 10%. Although statistical methods used for the studies were given in most publications (84%), sample size calculation and statistical assumption were rarely described. Most publications mentioned the IACUC approval, but only 8% mentioned welfare-related assessments and interventions, and only 4% mentioned any implications of experimental methods or findings for 3R. We may recommend the revision of the present IACUC proposal to collect more detailed information and improving educational program for animal researchers according to the ARRIVE guideline.

Anthropogenic food provisioning and immune phenotype: Association among supplemental food, body condition, and immunological parameters in urban environments.

Direct or indirect supplemental feeding of free-ranging animals occurs worldwide, resulting in significant impacts on population density or altered demographic processes. Another potential impact of increased energy intake from supplemental feeding is altered immunocompetence. As immune system maintenance is energetically costly, there may be trade-offs between immune responses and other energy-demanding physiological processes in individual animals. Although increased availability of food sources through supplemental feeding is expected to increase the overall immunocompetence of animals, empirical data verifying the association between supplemental feeding and different immune parameters are lacking. Understanding the potential influence of supplemental feeding on immune phenotypes is critical, as it may also impact host-pathogen dynamics in free-ranging animals. Using urban stray cats as a study model, we tested for associations between the intensity of supplemental feeding due to cat caretaker activity (CCA); body condition; and immune phenotype (bacterial killing assay (BKA), immunoglobulin G (IgG) concentration, and leukocyte counts). Significantly higher bacterial killing ability was observed in cats from high CCA districts, whereas higher IgG concentration and eosinophil counts were observed in cats from low CCA districts. Other leukocyte counts and body condition indices showed no significant association with CCA. We observed varying patterns of different immune components in relation to supplemental feeding. Out data suggest that supplemental feeding influences immune phenotype, not only by means of energy provisioning, but also by potentially reducing exposure rates to parasite infections through stray cat behavioral changes.

Rabies Outbreaks and Control during the Japanese Colonial Period in Korea.

Rabies became one of the critical zoonoses in the modern urban environment since pet keeping culture became widespread in the Western countries in the 18th century. The sanitary policy against rabies was a forceful tool for the colonial rulers in the 19th century. This study describes the rabies outbreaks in the context of prevention methods, experts' engagement and the public response to the policies based on the statistics, regulations and newspaper articles on rabies in Korea during the Japanese colonial period. Based on the changes in the rabies policies, this study divides the time period into three phases. First phase (1905- 1914) was characterized with the first epizootics investigation in Korea in 1905 and the "Domestic dog control regulation" in 1909, which legitimated elimination of dogs without owners' name tags. In the second phase (1915-1926), rabies was designated as a reportable disease by the "Act on Prevention of Domestic Animal Infectious Diseases (1915)" and thousands of dogs were slaughtered every year for rabies prevention. In the third phase (1927-1945), vaccination for dogs became a main intervention. From 1927 to 1942, 760,515 dogs were vaccinated. However, the broad scale rabies control projects over these decades did not seem to decrease the outbreaks of rabies because they did not reflect the rabies situation in Korea. Furthermore, the rabies control policy of the Japanese colonial government was criticized by the public for its violence against dogs and humans, for causing conflicts between social classes, and for lack of understanding of traditional human-dog relationship.

Infections by pathogens with different transmission modes in feral cats from urban and rural areas of Korea.

In this study, we examine prevalences of three infectious pathogens with different transmission modes (Bartonella henselae, hemoplasma, and Toxoplasma gondii) in feral cats from urban and rural habitats. Infection status of the three pathogens in blood samples (n = 117) was determined through molecular or serological diagnostic methods. Overall prevalence of hemoplasma, Toxoplasma gondii, and Bartonella henselae was 47.9%, 50%, and 35.7%, respectively. Comparing the two habitats, only seroprevalence of Bartonella henselae was significantly higher in urban cats. Based on the results, we discuss how pathogens with distinct transmission modes may show different prevalence between urban and rural habitat types.

Evaluation of biochemical and haematological parameters and prevalence of selected pathogens in feral cats from urban and rural habitats in South Korea.

OBJECTIVES: In this study, we evaluated the potential association between the habitat types of feral cats and the prevalence of selected infectious pathogens and health status based on a set of blood parameters. METHODS: We live-trapped 72 feral cats from two different habitat types: an urban area (n = 48) and a rural agricultural area (n = 24). We compared blood values and the prevalence of feline immunodeficiency virus (FIV), feline leukaemia virus (FeLV) and haemotropic Mycoplasma infection in feral cats from the two contrasting habitats. RESULTS: Significant differences were observed in several blood values (haematocrit, red blood cells, blood urea nitrogen, creatinine) depending on the habitat type and/or sex of the cat. Two individuals from the urban area were seropositive for FIV (3.0%), and eight (12.1%) were positive for FeLV infection (five from an urban habitat and three from a rural habitat). Haemoplasma infection was more common. Based on molecular analysis, 38 cats (54.3%) were positive for haemoplasma, with a significantly higher infection rate in cats from rural habitats (70.8%) compared with urban cats (47.8%). CONCLUSIONS AND RELEVANCE: Our study recorded haematological and serum biochemical values, and prevalence of selected pathogens in feral cat populations from two different habitat types. A subset of important laboratory parameters from rural cats showed values under or above the corresponding reference intervals for healthy domestic cats, suggesting potential differences in the health status of feral cats depending on the habitat type. Our findings provide information about the association between 1) blood values (haematological and serum biochemistry parameters) and 2) prevalence of selected pathogen infections and different habitat types; this may be important for veterinarians who work with feral and/or stray cats and for overall cat welfare management.

Continuing Veterinary Medical Education Needs Assessment of Small Animal Practitioners in South Korea.

This first survey of small animal veterinarians in Korea explores demographic patterns, previous learning experiences, and program preferences for continuing veterinary medical education (CVME). Data were analyzed to identify and describe learning needs and preferences. Respondents' average CVME hours (38.4 hours/year) exceeded the mandatory 10 hours per year. Almost all respondents recognized the importance of CVME. Lack of time and travel distance were identified as significant barriers to CVME participation. CVME courses scheduled after 9 p.m. on weekdays with a registration fee of up to $50 US per hour were preferred. Respondents clearly defined the educational quality criteria of preferred CVME programs: delivery in a series of interventions in a small seminar format, with lectures on theory combined with practical skill-building wet labs taught by experienced veterinarians and board-certified specialists. Small animal veterinarians in Korea are enthusiastic life-long learners who are strongly motivated to select CVME learning activities based on self-identified needs. The changing environment of veterinary medicine in Korea demands an evolution of CVME quality criteria, such as clear program goals reflecting veterinarians' educational needs and desirable competencies, and specific measurable learning objectives. Moreover, the current accreditation system, which does not encourage hands-on skill development formats, needs urgent improvement.

Anaplasma sp. and hemoplasma infection in leopard cats (Prionailurus bengalensis euptilurus) from Korea.

This study examined the occurrence of Anaplasma spp. and hemoplasma infection in leopard cats, Prionailurus bengalensis euptilurus, in Korea. Twenty-nine biological samples were tested by molecular analysis. Two (6.9%) and eight (27.6%) tested specimens were positive for Anaplasma bovis and hemoplasma infection, respectively. Based on our results, Anaplasma/Ehrlichia spp. and hemoplasma are regularly infecting leopard cat populations of Korea. Considering their endangered status, regular monitoring of infection by arthropod-borne pathogens known to cause clinical symptoms in feline hosts such as Anaplasma/Ehrlichia spp. and hemoplasma would be crucial as part of ongoing conservation efforts.

Glucocorticoid receptor changes associate with age in the paraventricular nucleus of type II diabetic rat model.

Diabetes is a metabolic disorder that is associated with the dysregulation of a number of systems within the body. In the present study, we investigated glucocorticoid receptor (GR) immunoreactivity and its protein levels in the paraventricular nuclei of 4-, 12-, 20- and 30-week-old Zucker diabetic fatty (fa/fa, ZDF) and in Zucker lean control (fa/+ or +/+, ZLC) rats, because the progressive induction of diabetes is detectable in this model after 7 weeks of age and chronic diabetic conditions are maintained after 12 weeks of age. GR immunoreactivity was detected in parvocellular paraventricular nuclei and this and GR protein levels were exponentially increased according to the ages. In particular, GR immunoreactivities and protein levels were markedly more increased in 30-week-old ZDF rats than in age-matched ZLC group and in younger ZDF group. The present study suggests that GR immunoreactivity and its protein level is associated with a degenerative phenotype in the hypothalamus of from 12-weeks old in the ZDF rat type II diabetes model.

Increasing production in Korean shrimp farms with white-spot syndrome virus PCR-negative brood stock.

White-spot syndrome virus (WSSV) is a devastating, infectious virus affecting shrimp. Although sensitive techniques involving PCR have been developed to assist farmers in screening shrimp (brood stock) for WSSV prior to stocking ponds, such practices have not yet been applied in Korea. Despite the rationality of implementing screening, there has been some doubt as to whether the stocking of WSSV-PCR-negative fry epidemiologically decreases white-spot disease outbreaks. Here, we report a retrospective analysis of data from shrimp farms in the western coast of Korea where WSSV-PCR-negative brood stocks were used to stock rearing ponds. A total of 366 shrimp from Heuksan Island were sampled for WSSV with PCR. Of the tested shrimp, 7.2% (28 brood stocks) were identified as WSSV positive; only WSSV-PCR-negative shrimp were used for brood stocks. Total unit production (final shrimp production/ the area of the ponds) was higher, at 1.96, in ponds where WSSV-PCR-negative shrimp were used, as compared with 1.02 in other ponds in Korea in 2004. This retrospective analysis of WSSV in Korea may be useful to the shrimp aquaculture industry, suggesting a testable hypothesis that may contribute to the eventual control of WSSV outbreaks.

[1918 influenza pandemic in Korea: a review on Dr. Schofield' article].

The article "Pandemic influenza in Korea with special references to its etiology," published in JAMA in April, 1919 by Dr. Frank William Schofield, is a valuable material reflecting the influenza pandemic situation in 1918 in Korea. It contains the case reports of influenza infected patients and the results of the bacteriological experiments. Dr. Schofield worked as a bacteriology professor in Severance Union Medical College in Seoul from 1916 to 1920. His academic activities are lesser-known than the role of contributor of Korean independent movement. However, he was a remarkable veterinarian and scientist. According to Dr. Schofield, the number of Influenza infected population in Korea in 1918 was supposed to be 4,000,000 to 8,000,000, which corresponds with other resources (6.7 per 1,000 in Gangwon province). Considering the cases which were not registered as influenza infection by misdiagnosis of pneumonia complication the sum should be higher. However, the estimated crude influenza death rate from the reports by the Japanese colonial government was only 2.38 (per 1,000). Dr. Schofield and his colleague tried to culture "Pfeiffer Bacillus" from the sputum and blood specimens of patients showing typical influenza symptoms. The bacterium was mistakenly considered as the influenza agent till the virological nature of influenza was discovered in the 1930s. From the results of his study he seemed to agree that "filterable virus" was the influenza agent and the secondary infection of the bacillus caused respiratory symptoms. He also reported on the influenza vaccination during the epidemics. Dr. Schofield's article confirms that the damage caused by the influenza outbreak in Korea was as great as in other Asian countries or even worse. It also gives information about the researches and education on the etiology and vaccination of influenza based on the germ theory in the medical colleges in Korea, which adopted the western medical educational system in the early 20th century.
