  • Since Patient Zero of MERS was diagnosed in May 20, 2015, cases of MERS continued to grow. The current situation, which people have been confirmed to be infected, suggested that contaminated indoor air could be the potential cause of hospital-acquired infections. It is important to address the indoor air quality in hospitals because pathogens can spread through air. While the heating, ventilating and air conditioning(HVAC) system is useful managing indoor air quality in hospitals, it can transmit the pathogens if operated improperly. Therefore, it is necessary to remove contaminants in hospitals and operate the HVAC system according to the guidelines, in order to maintain clean indoor air.

  • Purpose: The purpose of this study was to provide the basic data of a comprehensive counter-plan to promote health for people by comparing various factors related to cancer outbreak factors including general characteristics, health-related lifestyles, health promoting behaviors, perceived healthy status, life event stress and health care seeking behaviors with cancer patients and health people. Method: The study was designed to be a retrospective-comparison-survey-study and its data was collected through 5 types of questionnaires from September 2003 to December 2003. Results: Cancer patients had lower education and household income, and many of them had no occupation. Cancer patients had a higher rate of smoking and drinking periods. Exercise level was higher in healthy people. However, Cancer patients were better in sleep and rest. In comparison with health promoting behaviors, it was higher in healthy people than in cancer patients but the two groups had no significant differences statistically. The perceived health status was higher in healthy people than in cancer patients. The health care seeking behaviors were higher in healthy people than in cancer patients. Cancer patients and healthy people's life event stress had no significant differences statistically. Conclusion: As a result of comparative analysis of cancer patients and healthy people's health risk factors, smoking, drinking period, regular exercise and health care seeking behaviors were suggested as direct or indirect risk factors for cancer patients. These finding can be applied to health promoting behavior programs to keep and promote optimal health status as well as to prevent cancer disease.

  • Objectives: The purpose of this study was to investigate the effect subjective symptoms of malocclusion has on the patient's quality of life related to oral health. Methods: A self-administered survey was conducted on adults aged 20 years, with a total of 308 copies of the response sheets analyzed. Results: The degree of subjective symptoms of malocclusion was highest in the group of those in their 20s when looked at across different age groups, and those who had a final education of middle school. In addition, the quality of life related to oral health was the highest in middle school graduates and among those in Gyeonggi province. The degree of malocclusion symptom according to oral health behavior was highest in 1-2 weeks of drinking when smoking in a smoking state, and quality of life related to oral health was higher in smokers than in non-smokers. The greater the subjective symptoms of malocclusion, the lower the quality of life related to oral health. Conclusions: It was found that the subjective symptoms of malocclusion decreased quality of life related to oral health. As such, quality of life related to oral health can be improved through aesthetic and functional improvement efforts to decrease the subjective symptoms of malocclusion.

  • In many cases, obesity is associated with metabolic disorders. Recently, natural compounds that may be beneficial for improving obesity have received increasing attention. Bitter melon has received attention as a diabetes treatment. $NAD^+$-dependent deacetylase (Sirtuin 1, SIRT1) has emerged as a novel therapeutic target for metabolic diseases. In this study, ethanol extract of bitter melon (BME) suppressed adipocyte differentiation and significantly increased the expression of SIRT1 in fully differentiated 3T3-L1 cells. Moreover, it enhanced the activation of AMP-activated protein kinase (AMPK). In high-fat diet (HFD)-fed induced-obesity mice, BME suppressed HFD-induced increases in body weight and white adipose tissue (WAT) weight. BME also increased the expression of SIRT1 and suppressed peroxisome proliferator-activated receptor and sterol regulatory element binding protein 1 expressions of WAT from HFD-fed mice. These findings suggest that BME prevents obesity by activating the SIRT1 and AMPK pathway and that it may be a useful dietary supplement for preventing obesity.

  • 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.

  • Purpose: The aim of this study was to conduct a systematic review of randomized controlled studies from 2012 to present that explore the diagnostic accuracy of clinical tests used for diagnosing anterior cruciate ligament (ACL) injury. Methods: Study design: Systematic review. Literature search of the PubMed and Scholar databases was conducted using keywords related to diagnostic accuracy of clinical tests for ACL injury. The PRISMA Guidelines were followed to conduct this study. The Cochrane Risk of Bias Tool was utilized to assess the quality of each included study. Results: As a result, 8 studies were included, and 6 clinical tests used in ACL tears were evaluated for diagnostic accuracy. The pivot shift test was reported as having the highest +LR (29.5) value with a sensitivity of 59% and a specificity of 98%. However, the test with the lowest -LR value was the lever test, and the values were as follows: -LR (0.08), +LR (4.7), specificity (80%), sensitivity (94%). Conclusion: In this study, it was concluded that a single clinical test is not sufficient to determine the presence of ACL injury. Test combinations have a higher diagnostic accuracy than a single test. In this study, the accuracy of the clinical tests was examined without considering the amount of ACL rupture and acute-chronic condition. Further research is required to examine the impact of these two factors on diagnostic accuracy of clinical test.

  • The migration, dedifferentiation, and proliferation of vascular smooth muscle cells (VSMCs) are responsible for intimal hyperplasia, but the mechanism of this process has not been elucidated. WD repeat domain 1 (WDR1) promotes actin-depolymerizing factor (ADF)/cofilin-mediated depolymerization of actin filaments (F-actin). The role of WDR1 in neointima formation and progression is still unknown. A model of intimal thickening was constructed by ligating the left common carotid artery in Wdr1 deletion mice, and H&E staining showed that Wdr1 deficiency significantly inhibits neointima formation. We also report that STAT3 promotes the proliferation and migration of VSMCs by directly promoting WDR1 transcription. Mechanistically, we clarified that WDR1 promotes the proliferation and migration of VSMCs and neointima formation is regulated by the activation of the JAK2/STAT3/WDR1 axis.

  • A brief emergency planning educational presentation was taught during work hours to a convenience sample of employees of various workplaces in Northern Missouri, USA. Participants were familiarized with details about how an emergency plan is prepared by management and implemented by management-employee crisis management teams - focusing on both employee and management roles. They then applied the presentation information to assess their own organization's emergency preparedness level. Participants possessed significantly (p < 0.05) higher perceptions of their organization's level of emergency preparedness than non-participants. It is recommended that an assessment of organizational preparedness level supplement emergency planning educational presentations in order to immediately apply the material covered and encourage employees to become more involved in their organization's emergency planning and response. Educational strategies that involve management-employee collaboration in activities tailored to each workplace's operations and risk level for emergencies should be implemented.
