Myxomatous mitral valve disease (MMVD) in dogs is a heart disease that is characterized by histopathologic changes in cardiomyocytes, which ultimately result in valve degeneration and blood regurgitation due to structural changes in the heart valves. A number of studies have been conducted with the objective of identifying prognostic factors that may influence the prognosis of dogs with MMVD. Nevertheless, there is a paucity of research examining the factors that predict MMVD stage progression as defined by the American College of Veterinary Internal Medicine. The objective of this study was to examine whether there are factors associated with stage progression within one year of diagnosis in dogs diagnosed with subclinical MMVD (stage B1 or B2) using physical examination findings, clinicopathologic biomarkers, and echocardiographic markers. This is a retrospective study of veterinary practice performed at Chungbuk National University Animal Hospital. The electronic medical record of the hospital was searched to obtain clinical records of canine patients diagnosed with subclinical MMVD over an 11-year period. For each patient cohort, a logistic regression analysis was conducted. The variables were initially selected using the backward elimination method, and the optimal logistic regression model was determined by removing the independent variables with the largest variance inflation factor. Among the independent variables examined in this study, heart murmur intensity was identified as a statistically significant predictor of stage progression within one year for subclinical MMVD, a finding that aligns with those of previous studies. No other independent variables were found to be significantly associated with subclinical MMVD stage progression. This is the inaugural exploratory study to concentrate on blood test results, a relatively straightforward and quantifiable test result that can be readily obtained in primary care veterinary clinics, among the factors that may be associated with the progression of subclinical MMVD stages.

본 연구는 종합병원에서 근무하는 초보간호사의 임상수행능력에 영향을 주는 요인을 알아보고자 실시하였다. 초보간호사 155명을 대상으로 2020년 9월 11일부터 9월 30일까지 설문조사 하였으며, 수집된 자료는 SPSS 프로그램을 이용하여 t-test, ANOVA, Scheffe test, Person’s correlation coefficients, 다중회귀분석을 하였다. 월경곤란증은 2.77점, 임상수행능력은 3.44점 이었고 월경곤란증과 임상수행능력은 유의한 음의 상관관계를 보였다(r=-.226, p=.002). 임상수행능력에 유의한 영향을 준 것은 자율신경계 반응이고(β=-.261, p= .001) 설명력은 22.1%였다. 따라서 초보간호사의 임상수행능력을 증진시키기 위해 월경곤란증의 자율신경계 반응 완화를 위한 중재 교육 프로그램이 필요하다.

1999년 6월부터 2002년 4월까지 총 2년 11개월 간 전국에서 발생한 소 유조사산에 대한 임상학적 연구결과는 다음과 같았다. 1. 계절별 소 유조사산 발생은 여름에 다른 계절에 비해 많이 발생하였다. 이는 여름철의 고온 다습한 기후와 낮은 우군관리 집중도에 기인한다고 사료된다. 2. 임신우의 산차별 유조사산 발생 비율을 조사한 결과 산차가 낮은 소에서 많이 발생하였다. 이는 유조사산의 원인이 임신우의 산차수에 있기보다는 산차수가 높은경우 사육되는
