PURPOSE: The purpose of this study was to identify muscle atrophy in critically ill patients on ventilators. A comparison was made between limb circumferences and muscle areas on the day of admission to an intensive care unit (ICU) and on the 8th day after admission. METHODS: The data were collected from 30 critically ill patients using ventilators at S hospital ICU in Seoul during the period from October 2005 to April 2006. Limb circumferences and skinfold thickness were measured on the day of admission and on the 8th day after admission to the ICU. Limb circumferences and skinfold thickness were measured on the right mid-arm, right mid-thigh, and right mid-calf using a measuring tape and a skinfold calipers. Limb muscle areas were calculated by an equation after measuring limb circumferences and skinfold thickness. The data were analyzed by paired t-test and independent t-test. RESULTS: 1) Mid-arm circumference, mid-thigh circumference and mid-calf circumference on the 8th day after admission to the ICU were significantly less than those on the day of admission to the ICU, 2) Mid-arm muscle area, mid-thigh muscle area and mid-calf muscle area on the 8th day after admission to the ICU were significantly less than those on the day of admission to the ICU, 3) Steroid and vecuronium medication didn't affect changes in limb circumferences (mid-arm, mid-thigh, mid-calf) and muscle areas (mid-arm, mid-thigh, mid-calf) on the 8th day after admission to the ICU compared to the day of admission. CONCLUSION: Limb muscle atrophy may occur on the 8th day after admission to the ICU in critically ill patients using ventilator.

PURPOSE: This study was to develop and evaluate an individualized education program based on self-efficacy for patients with kidney transplantation in Korea. METHODS: A nonequivalent control group pretest-posttest design was used. The participants consisted of 43 patients who underwent kidney transplants at one hospital in Seoul, from July 2012 to April 2013. The experimental group received an individualized education based on self-efficacy in the hospital and follow-up telephone consultation in the 2nd and 3rd week after discharge. The control group received a routine discharge education. Knowledge, self-efficacy, and compliance related to kidney transplant were measured and analyzed by frequency, average, Mann-Whitney U test, Fisher's exact test, independent t-test, and chi2-test using SPSS Win 20.0. RESULTS: Significant differences were found in self-efficacy between the experimental group and the control group. But no significant differences were found in knowledge and compliance between two groups. The scores of several items on monitoring health status in compliance were higher in the experimental group than those of the control group. CONCLUSION: The results of this study demonstrate the fact that an education program based in self-efficacy for patients with kidney transplant would be effective in improving self-efficacy and the ability to monitor their health status.

PURPOSE: The study was performed to investigate the effects of empathy on interpersonal relationships through the mediating effect of ego-resilience in nursing students. METHODS: Data were collected from June 5 to 30, 2018 using a self-report questionnaire measuring empathy, interpersonal relationships and ego-resilience. The sample was 204 nursing college students. SPSS WIN 23.0 programs were used to analyze the data. RESULTS: Ego-resilience was positively related to empathy (r=.37, p < .001) and interpersonal relationships (r=.36, p < .001) and empathy was positively related to interpersonal relationships (r=.37, p < .001). Regression analysis showed that ego-resilience was affected by empathy (β=0.37, p < .001), interpersonal relationships were affected by empathy (β=0.37, p < .001). Interpersonal relationships were affected by empathy (β=0.28, p < .001) and ego-resilience (β=0.26, p < .001). Therefore ego-resilience mediates between empathy and interpersonal relationships. CONCLUSION: It is necessary to develop an effective intervention program to improve nursing students' empathy and ego-resilience.

PURPOSE: This study aimed to investigate the effect of smoking duration, smoked cigarettes per day and smoking cessation period on pulmonary function among ex-smokers: based on the 6th Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: This study was analyzed using the 6th KNHANES data. Pulmonary function tests were performed on a total of 4,214 adults (>40 years old). A total of 770 adults ex-smokers were eligible for inclusion in the final analysis. Forced vital capacity (FVC), forced expiratory volume in one second (FEV₁) and FEV₁/FEV were measured to evaluate pulmonary function. RESULTS: This study showed that there were significant differences in both FEV₁ and FVC values based on gender, age and height, among ex-smokers. FEV₁/FVC significantly differed by age, height and the smoking duration prior to smoking cessation. Multiple regression analysis revealed that, FEV₁/FVC accounted for 26.0% of the variance by age, height and smoking duration. There was a difference in the mean value of FEV₁/FVC with or without smoking for more than 10 years. CONCLUSION: This study's findings show that smoking for over 10 years in an ex-smoker can lead to problems with the respiratory system. The long-term cigarette has progressive ill effects on the respiratory system.

Purpose: This study aimed to identify the effect of nursing students' empathy and self-esteem on problem-solving ability through the mediated effect of communication skills. Methods: Data were collected from 179 nursing students between 1 October and 30 October, 2018 from three universities in Gyeonggi-Do. Data on subjects’ general characteristics, empathy, self-esteem, communication skills, and problem solving ability were collected using a structured self-reporting questionnaire. Results: Of the total subjects, 89.9% were female. The subjects' empathy was 3.40±0.36, self-esteem was 3.16±0.56, communication skills was 3.65±0.48, and problem-solving ability was 3.52±0.42. Communication skills showed a partial mediating effect on the relationship between empathy and problem solving ability. Communication skills also showed a partial mediating effect on the relationship between self-esteem and problem solving ability. Conclusion These findings indicate that it will be more effective to develop strategies that can improve empathy, self-esteem, and communication skills together when developing programs that improve problem-solving ability.

Purpose: Compliance in kidney transplant recipients is critical for a positive prognosis. Especially compliance with medications after kidney transplantation is a major health care issue with implications for graft rejection and graft loss. But the definition of compliance in transplantation varies among centers. The purpose of this study was to clarify the concept of compliance in kidney transplant recipients. Methods: A literature search was conducted using RISS, MEDLINE, CINAHL. The concept analysis was guided by the methodology posited by Walker and Avant. Results: In this study, we found the attributes of the concept: ‘compliance with immunosuppressive medication’, ‘compliance with follow-up’, ‘compliance with early detection of graft rejection and complication’, and ‘compliance with prevention of complication’. The antecedents of ‘compliance in kidney transplant recipients’ included ‘having a kidney transplant surgery’ and ‘normal function of transplanted kidney’. The consequences of ‘compliance in kidney transplant recipients’ included ‘affecting the function of the transplanted kidney’ and ‘affecting the health of kidney transplant recipients. Conclusion This study may contribute to the development of tools for measuring compliance in kidney transplant recipients, as well as benefit nursing interventions research to increase compliance in kidney transplant recipients.

PURPOSE: The aim of this study was to verify the effects of daily 2% chlorhexidine gluconate (CHG) bathing on the acquisition of multidrug-resistant organisms (MDRO) and healthcare-associated infection (HAI) in a medical intensive care unit (MICU). METHODS: The study was a randomized controlled group posttest only design, involving 91 patients in MICU at a tertiary hospital (47 patients in the experimental group and 44 patients in the control group). The 2% CHG bathing was performed daily according to bathing protocol to the patients in the experimental group, and traditional bath was performed every three days to those in the control group. Fisher's exact test and χ² test were used to analyze the data. RESULTS: MDRO were found in 6 patients of the experimental group and in 15 patients of the control group. The difference was statistically significant (p=.016). HAI occurred in 2 patients of the experimental group and in 7 patients of the control group. The difference was not statistically significant (p=.084). CONCLUSION: The results confirmed that daily bathing with CHG was effective in reducing the incidence of MDRO acquisition. Therefore, it is expected that daily bathing with CHG will be used as an effective nursing intervention to reduce the incidence of MDRO acquisition.

PURPOSE: We hypothesized that Purkinje potential and their preferential conduction to the left ventricle (LV) posteroseptum during sinus rhythm (SR) are part of reentrant circuits of idiopathic left ventricular tachycardia (ILVT) and reentry anchors to papillary muscle. MATERIALS AND METHODS: In 14 patients with ILVT (11 men, mean age 31.5+/-11.1 years), we compared Purkinje potential and preferential conduction during SR with VT by non-contact mapping (NCM). If clear Purkinje potential(SR) was observed in the LV posteroseptum and the earliest activation site (EA) of preferential conduction at SR (EASR) was well matched with that of VT (EAVT), EASR was targeted for radiofrequency catheter ablation (RFCA). Also, the anatomical locations of successful ablation sites were evaluated by echocardiography in five additional patients. RESULTS: 1) All induced VTs exhibited clear Purkinje potential(VT) and preferential conduction in the LV posteroseptum. The Purkinje potential(VT) and EAVT was within 5.8+/-8.2 mm of EASR. However, the breakout sites of VT were separated by 30.2+/-12.6 mm from EAVT to the apical side. 2) Purkinje potential(SR) demonstrated a reversed polarity to Purkinje potential(VT), and the interval of Purkinje potential(SR)-QRS was longer than the interval of Purkinje potential(VT)-QRS (p<0.02) 3) RFCA targeting EASR eliminated VT in all patients without recurrence within 23.3+/-7.5 months, and the successful ablation site was discovered at the base of papillary muscle in the five additional (100%) patients. CONCLUSION: NCM-guided localization of EASR with Purkinje potential(SR) matches well with EAVT with Purkinje potential(VT) and provides an effective target for RFCA, potentially at the base of papillary muscle in patients with ILVT.

Purpose: This qualitative study was to understand the awareness of epidemiological investigation tasks for nurses who were in charge of coronavirus disease 2019 (COVID-19) epidemiological investigations. Methods: Before data collection, written consent was obtained from 13 participants, and the data were then collected from September 1 to December 31, 2021. Individual interviews were conducted and recorded by video interview using Zoom, and data were transcribed verbatim. Four themes were derived by using the qualitative thematic analysis method. Results: The participants perceived that epidemiological investigations were burdensome but that the field work was important, and that expertise and collaboration were required. The participants started work without preparation due to the explosive increase in the number of confirmed COVID-19 cases, and they recognized work conflicts, unstable employment, and exhaustion as obstacles to their work performance. On the other hand, the participants took pride in contributing to the national epidemiological investigation and control and felt a sense of responsibility as nursing professionals. Finally, participants mentioned that the training of infectious disease practitioner was important for work improvement. Conclusion Further research is needed on the development of standardized manuals for the training of nursing personnel as infectious disease specialists through the job analysis of epidemiological investigators.
