Background: The purpose of this study was to investigate nurses' knowledge and performance ability of Defibrillator. Methods: The participants in this study were 121 nurses who have been working in a general hospital located in G region. The measuring tools of this study were developed on the basis of guidelines from American Heart Association and Korea Association of Cardiopulmonary Resuscitation. The knowledge of defibrillator was measured by self-report questionnaire, and the performance ability of defibrillator was measured by observation of the participants. The period of collected date was from May 15 to June 15 in 2016. The collected data were analyzed by using SPSS 19.0 program. Results: The mean score about knowledge of defibrillator was 2.79±2.42. The mean score about performing ability of defibrillation was 6.44±3.39. The knowledge of defibrillator was a significant difference with age, working area, working carrier, experience of using defibrillator. The performance ability of defibrillator was a significant difference with age, working area, working carrier, experience of using defibrillator. There was a significant positive correlation between knowledge and performance ability of defibrillator. Conclusions The finding suggests developing the knowledge and the performance ability of defibrillator on going refresher courses and training programs, including the related nursing practice guidelines to improve the knowledge and performance ability of defibrillator.

PURPOSE: The purpose of this study was to examine the validity of student ratings of instruction by analyzing their relationships with several variables, including gender, academic rank, specialty, teaching time, and teaching method, at a medical school. METHODS: This study analyzed the student ratings of 297 courses at Ajou University School of Medicine in 2013. SPSS version 12.0 was used to analyze the data and statistics by t-test, analysis of variance, and Scheffe test. RESULTS: There were no statistically significant differences in student ratings between gender, rank, and specialty. However, student ratings were significantly influenced by teaching times and methods (p<0.05). Student ratings were high for teaching times of 10 hours or more and small-group learning, compared with lectures. There was relatively mean differences in students ratings by teaching times, specialty and rank, although the difference in ratings was not statistically significant. CONCLUSION: Student ratings can be classified by teaching time and method for summative purposes. To apply student ratings to the evaluation of the performance of faculty, further studies are needed to analyze the variables that influence student ratings.

There is a dearth of Korean studies on dehydration, one of the health risks for adult women. This study analyzed the subjects of the 2016∼2018 National Health and Nutrition Examination Survey (KNHANES) to investigate the relationship between nutrient intake ratios and sedentary time in dehydrated women. Body mass index and waist circumference in the dehydrated group (DG) were significantly higher than the normal group (NG). Intake of other liquids in the DG was significantly higher than in the NG, but total water intake in the DG was significantly lower than in the NG. Compared to the 600 sedentary minutes or more per day group, the odds ratio of dehydration was significantly higher in the less than 300 sedentary minutes per day group (1.871 [95% CI: 1.579∼2.215], P＜0.001). Compared to the drinking over 6.0 cups of water per day group, the odds ratio of dehydration was significantly higher in the 3 cups or fewer per day (OR [95% CI] is 1.198 times [1.019 to 1.408], P＜0.05), and 6.0 cups or fewer group (OR [95% CI] is 1.162 times [1.018 to 1.326], P＜0.05). The results of this study showed that the total water intake was relatively lower in the ≥600 sedentary minutes per day group compared to the 300 sedentary minutes per day group, making them more vulnerable to dehydration. The nutrient intake ratios were higher in the dehydration group than in the normal group. In conclusion, emphasis should be placed on the importance of hydration and nutrition education for adult women in the workplace.

PURPOSE: Progesterone resistance is thought to be a major factor that contributes to progression of endometriosis. However, it is not clear what causes progesterone resistance in endometriosis. This study aimed to assess whether cytokines or peritoneal fluid can affect progesterone receptor (PR) expression in endometrial cells and to verify whether PR expression is reduced in endometriosis. MATERIALS AND METHODS: The PR-B/A ratio was measured via real-time polymerase chain reaction after in vitro culture, in which endometrial cells were treated with either tumor necrosis factor-alpha (TNF-α), interleukin-1 beta, or peritoneal fluid obtained from women with advanced-stage endometriosis. Immunohistochemistry was performed to compare PR-B expression between eutopic and ectopic endometrial tissues from women with and without advanced-stage endometriosis. RESULTS: The PR-B/A ratio was significantly decreased by treatment with either TNF-α (p=0.011) or peritoneal fluid from women with advanced-stage endometriosis (p=0.027). Immunoreactivity of PR-B expression was significantly lower during the secretory phase than during the proliferative phase in endometrial tissues from control subjects (p<0.001). PR-B expression was significantly reduced in the eutopic endometrium (p=0.031) and ovarian endometrioma (p=0.036) from women with advanced-stage endometriosis compared with eutopic endometrium tissues from control subjects. CONCLUSION: Progesterone resistance in endometriosis may be caused by proinflammatory conditions in the pelvic peritoneal microenvironment.

Recurrent pneumothorax was associated with the menstrual cycle in two women 20 to 30 years age; this is referred to as catamenial pneumothorax. This form of pneumothorax occurs within 72 hours before or after the onset of menstruation. The pathophysiology underlying this condition is unknown. We report here on two cases of catamenial pneumothorax that were successfully treated by partial resection of the diaphragm.
