Rumen cannulation is used for nutritional and microbiological research, clinical diagnosis, and rumen component transfaunation. However, the cannulation procedure can affect parameters such as complete blood count findings, serum chemistry, and rumen fluid pH. The objective of this study was to evaluate the health risks related to the rumen cannulation procedure over a 1-month period. We did not identify significant differences in red blood cell numbers or morphologies between pre- and postoperative timepoints. Moreover, no inflammation or infection was detected. Despite the absence of apparent clinical signs after surgery, serum chemistry results revealed changes in blood urea nitrogen levels and the activities of liver enzymes, including aspartate transaminase, lactate dehydrogenase, and creatinine kinase, from postoperative days 1 to 14. Rumen fluid pH, as measured from samples collected via an orogastric tube, was slightly increased after a preoperative fasting period and on postoperative day 1 but decreased thereafter from postoperative day 4, indicating a minor influence of cannulation surgery on ruminal fluid pH. This is the first study to evaluate hematological parameters and rumen pH before and after rumen cannulation surgery in Hanwoo cattle. Further research is required to better elucidate the potential effects of rumen cannulation surgery on animal health.

Severe outbreaks of porcine epidemic diarrhoea virus (PEDV) have continued to re-emerge worldwide. Because of the high mortality rate of suckling piglets in PEDV outbreaks, the disease causes significant economic losses in the pig industry. The limited pre-existing immunity against this virus is thought to cause an explosive increase in infection in pig farms. This study aimed to evaluate the clinical symptoms of PEDV after intentional exposure (feedback). During the first few days of the outbreak in a breeding pig farm, 14 sows showed watery diarrhoea, and the disease subsequently spread rapidly throughout the barn. Pigs that were intentionally exposed to PEDV (n=251) showed watery diarrhoea (46.6%), reduced appetite (17.5%), and vomiting (6.0%). However, 75 exposed pigs (29.9%) showed no clinical signs of disease. Four weeks after the feedback challenge, 34 sows gave birth to litters of piglets, which survived with no diarrhoea. Five weeks after the start of the outbreak, PEDV was not detected in any of the examined samples, including environmental swabs. Thus, early diagnosis, prompt establishment of herd immunity, and strict application of biosecurity are good practices to reduce the mortality rates among new-born piglets and control economic losses in pig farms showing PEDV outbreaks.

Bovine dermatophytosis is a highly contagious disease that adversely affects animal growth and reduces meat and milk production. Nutritional deficiencies and immune status are suspected risk factors, but their roles remain unclear. This study investigates the association between trace minerals, vitamins, serum biochemical parameters, and immune-related cytokines with bovine dermatophytosis. Forty calves aged 6~7 months were selected and raised together on the same farm. They were divided into two groups: the control group (n=20) and the infected group (n=20). Serum was collected and analyzed for serum trace minerals, vitamins, biochemical parameters, and cytokine levels. Trichophyton verrucousm was isolated from infected calves. The infected calves had significantly lower zinc (P<0.001) and vitamin E (P=0.02) levels and significantly higher interleukin (IL)-6 (P=0.014) and IL-17A (P=0.018) levels. Regarding serum biochemical parameters, glucose (P=0.008) and total bilirubin (P=0.003) levels were significantly higher in the infected calves than in healthy ones. Hyperglobulinemia and high alkaline phosphatase levels were observed in the infected calves, without statistical significance. Our findings suggest the necessity of considering nutritional elements such as zinc and vitamin E for the prevention and treatment of bovine dermatophytosis. Additionally, the observed changes in immune and serum biochemistry factors post-infection may provide a foundation for future research on the host's biological responses to infection.

This study aims to grope for the factors that can influence consumer when they evaluate sports centers' service multilaterally in order to draw strategic operation methods for sports centers. This article examines the relationship among sports centers' service guarantee, service quality, service value, customer satisfaction, and customer loyalty. This study selects 2 sports centers located in Seoul and then conducts a survey to 200 members of the sports centers. The data collected go through frequency analysis, reliability analysis, and exploratory factor analysis with SPSS 16.0, and also AMOS 18.0 is utilized to perform confirmatory factor analysis and hypothesis verification. According to the study result First, service guarantee affects service quality positively while it does not affect customer loyalty. Second, service quality affects service value positively. Third, service value affects customer satisfaction and customer loyalty positively. Therefore this study has verified the marketing effectiveness of service guarantee in sports centers, so it can be said that the study has drawn practical operation methods.

Objectives: To examine the prophylactic antibiotic use in reducing surgical site infection. Methods: This was a retrospective study for patients aged 18 years and older who underwent gastrectomy, cholecystectomy, colectomy, cesarean section and hysterectomy. The data source was quality assessment data of the Health Insurance Review & Assessment Service gathered from medical records of 302 national hospitals. Prophylactic antibiotic use was defined as: timely antibiotic administration or inappropriate antibiotic selection. We performed hierarchical logistic regression to examine the association between prophylactic antibiotic use and surgical site infection with adjustment for covariates. Results: The study population consisted of 16 348 patients (1588 gastrectomies, 2327 cholecystectomies, 1,384 colectomies, 3977 hysterectomies and 7072 cesarean sections) and surgical site infection was identified in 351 (2.1%) patients. The rates of timely antibiotic administration and inappropriate antibiotic selection varied according to procedures. Cholecystectomy patients who received timely prophylactic antibiotic had a significantly reduced risk of surgical site infection compared with those who did not receive a timely prophylactic antibiotics (OR 0.64, 95% CI=0.50-0.83), but no significant reduction was observed for other procedures. When inappropriate prophylactic antibiotics were given, the risk of surgical site infection significantly increased: 8.26-fold (95% CI=4.34-15.7) for gastrectomy, 4.73-fold (95% CI=2.09-10.7) for colectomy, 2.34-fold (95% CI=1.14-4.80) for cesarean section, 4.03-fold (95% CI=1.93-8.42) for hysterectomy. Conclusions: This study examines the association among timely antibiotic administration, inappropriate antibiotic selection and surgical site infection. Patients who received timely and appropriate antibiotics had a decreased risk of surgical site infection. Efforts to improve the timing of antibiotic administration and use of appropriate antibiotic are needed to lower the risk of surgical site infection.
