  • This paper describes the epidemiological characteristics of bovine brucellosis in Korea during January 2000~September 2004, which encompasses the period when the incidence of bovine brucellosis increased abruptly. Data from the National Animal Infectious Disease Data Management System were used for this study. A range of epidemiological measures was calculated including annual herd and animal incidence. During the study period, there were 1,183 outbreaks on 638 farms. In beef cattle, annual herd incidence increased from 0.2 (2000) to 11.5 (2004, to September) outbreaks per 10,000 and annual animal incidence varied between 3.4 (2000) and 105.8 (2004, to September) per 100,000, respectively. On 401 (62.9%) infected farms during this period, infection was eradicated without recurrence. Recurrence of infection was significantly higher on farms where abortion was reported (53.3%), compared to farms where it was not (30.0%). On beef cattle farms, infection was introduced most frequently through purchased cattle (46.2%). Based on the results of this study, the establishment and spread of brucellosis in the Korean beef cattle population were mainly due to incomplete or inappropriate treatment of aborted materials and the movement of infected cattle.

  • Purpose: This study examined the clinical and epidemiological characteristics of intensive care unit (ICU) patients admitted or died in the emergency medical center with acute-poisoning to investigate the variables related to the prognosis. Methods: The data were collected from poisoning patients admitted or died in the emergency medical center of a general hospital located in Seoul, from January 2014 to February 2020. The subjects of this study were 190 patients. The medical records were screened retrospectively, and the clinical and epidemiological characteristics of the patients in the emergency room (ER) and ICU were examined to investigate the contributing factors that influence the poor prognosis. Results: The study analyzed 182 patients who survived after being admitted to the intensive care unit (ICU). The results are as follows. The mental change (87.4%) was the most common symptom. Sedative poisoning (49.5%) was the commonest cause. For most patients, pneumonia (26.9%) was the most common complication. Hypotension (23.7%), tachycardia (42.1%), fever (15.8%), seizures (10.5%), dyspnea (2.6%), high poisoning severity score (PSS), type of toxic material, mechanical ventilator application (39.5%), inotropes application (39.5%), and pneumonia (55.3%) were correlated the LOS over 5 days in the ICU. 8 patients died. In the case of death pesticides and carbon monoxide were the main toxic materials; tachycardia, bradycardia, and hypotension were the main symptoms, and a mechanical ventilator and inotropes were applied. Conclusion: Patients with unstable vital signs, high PSS, and non-pharmaceutical poisoning had a prolonged LOS in the ICU and a poor prognosis.

  • Objectives: This study investigated the role of Korean medicine doctors in the national quarantine system and the status of their duties through questionnaire surveys and in-depth interviews with Korean medicine staff who participated in COVID-19 work. Methods: We developed a questionnaire survey to investigate the status and perception of Korean medicine doctors' participation in responding to infectious diseases, and the results were derived by conducting frequency analysis and T-test using SPSS program. The measurement variables of this study were the status of COVID-19 related work participation and perception of Korean medicine doctors' role in infectious diseases, and the maximum significance level was 0.05. Results: There were 300 respondents to the survey, and as for the COVID-19 related work, Korean medicine treatment for COVID-19 patients accounted for the most(52.7%), and various preventive and treatment tasks such as epidemiological investigations and specimen collection were conducted. Conclusion: According to this study, it was confirmed that there are sufficient legal and administrative grounds for Korean medicine doctors to perform specimen collection and epidemiological investigations. Therefore, it is necessary to prepare a policy framework to solidify the status of Korean medicine doctors in national infectious diseases in the future.

  • Deliberate self-harm (DSH) is the act of deliberately harming your own body, such as cutting or burning yourself, without suicidal intent. It has especially become a problem among adolescents and college-age students in institutional settings such as boarding schools, Greek houses, detention centers and hospitals. We focus on contagion of DSH among adolescents and young adults by creating a deterministic epidemiological model. We study the impact of actual peer pressure, virtual peer pressure (the Internet) and treatment analytically in terms of a basic reproduction number through stability analysis of a system of ordinary differential equations. All parameters are approximated and results are also explored by simulations. The model shows that DSH is present in an endemic state in the population considered, and the control strategies are discussed.

  • Ten Listeria monocytogenes were isolated from clinical specimens and mussels, and their physio-biochemical characters were compared with the type strains. Ribotyping was used as a taxonomic tool to determine molecular epidemiological marker. Chromosomal DNA was cleaved with restriction enzymes HindIII and EcoRI. The fragment were subjected to Southern blot hybridization with 165 rDNA from B. subtilis by PCR. EcoRI patterns of Listeria strains showed 6 to 8 bands ranging from 0.75 kb to 11 kb band and they were classified into 6 groups. In comparison, HindIII patterns revealed that 5 to 7 bands ranging from 2.75 kb to 7.75 kb band and they classified into 5 groups. The various patterns of Listeria strains were observed within genus, species and isolated sources. 165 rRNA gene restriction patterns (ribotyping) are useful in epidemiological and taxonomic study.

  • Objective : We investigated relationship between tinnitus and temporomandibular disorder(TMD) and tried to find approach possibility in oriental medicine. Method : We searched Pubmed, Scopus, The Cocharane library and additional sources for published and unpublished trials. Search word was "Tinnitus and TMD" Result : We investigated 18 studies. We divided these studies into three parts, epidemiological studies, mechanical studies and treatment studies. In many epidemiological studies. there was significant relationship between tinnitus and TMD. The mechanism was not clear but in recently several studies proposed neurological approach. TMD treatment showed significant improvement in tinnitus accompanied by TMD. Conclusion : In tinnitus accompanied by TMD, TMD treatment can be available to resolve or reduce tinnitus. Especially in oriental medicine acupuncture can be applied to treat this.

  • Epidermophyton floccosum was known to be a frequently isolated dermatophyte agent of dermatophytosis in Korea, which regularly responsible for a small percentage of tinea cruris, tinea pedis, tinea corporis and onychomycosis. The purpose of this study was to investigate epidemiologic aspects of E. floccosum isolated in 71 patients from January 1998 to December 2007. The incidence of E. floccosum. was 0.07% out of a total of 107,026 dermatophytosis. The ratio of male to female patients was 6.9:1. Involved tinea were tinea cruris 44 (62.0%), tinea pedis 20 (28.2%), tinea corporis 2 (2.8%), tinea manus 2 (2.8%), tinea unguium 2 (2.8%), tinea faciale 1 (1.4%).
