Purpose: : Developing infection control capabilities during the COVID-19 pandemic was critical. This study aimed to develop a simulation program to control patients with COVID-19 in nursing students and examine the effects on COVID-19 knowledge, COVID-19 nursing intention, self-efficacy learning, and clinical performance. Methods: : The study used nonequivalent control group pretest-posttest design. Sixty nursing students were recruited from two different colleges using purposive sampling. For the intervention group(n=30), the pretest was administered before the simulation program, involving six sessions of online lectures and simulation practices. Immediately, the posttest was conducted following the program. Results: : COVID-19 knowledge (t=9.87, p ＜.001), COVID-19 nursing intention (t=4.45, p ＜.001), learning self-efficacy (t=6.49, p ＜.001), and clinical performance (t=6.77, p ＜.001) increased significantly after the program, revealing the positive effect of the COVID-19 infection control simulation program in nursing students. Conclusion : The results of the study and the curriculum may be used as practical evidence for COVID-19 infection control in nursing schools and medical institutions.

Purpose: The purpose of this study was to examine the impact of encounters with customer violence on the mental health of customer service workers, and to verify the moderating effect of coworker support. Methods: Workers who indicated that they engaged directly with individuals other than coworkers for more than 25% of their working hours, such as customers, passengers, students, and patients, were the focus of the 6th Korean Working Conditions Survey in 2020. A total of 13,682 people were chosen as the final research subjects, responses from dishonest respondents who had picked "don't knowo answer" or indicated "reject" to pertinent topics such mental health level, were discarded. After adjusting for socio-demographic and vocational characteristics that influence mental health in customer service workers, a hierarchical regression analysis was executed, which incorporated input on customer violence experiences, coworker support, and interaction terms on a step-by-step basis. Results: It transpired that interactions with customer violence had a negative impact on workers' mental health. Additionally, it was shown that workers' mental health status as coworker support increased. Conclusion This study's limitations include differences in the period the questions were posed, and limitations in interpretation to all workers. And it is difficult to determine the relationship between the frequency of customer violence, occupational characteristics and mental health. Despite its limitations, this study makes an important contribution toward fostering an environment where coworkers can continue to help one another.

PURPOSE: This study aimed to identify the associated factors of the perceived health status of the elderly in Korea and to provide basic data for developing nursing interventions for the elderly's health management. METHODS: This study used a descriptive correlational research design. The subjects of this study were 335 elderly people over 60 yr living in an urban city. Data were collected through personal interviews using questionnaires from September 2006 to March 2007. Empirical indicators of perceived health status were measured by SF-36, nutritional screening initiative (NSI), activities of daily living (ADL) Index, and instrumental activities of daily living (IADL) scale. The collected data were analyzed by descriptive statistics, Pearson's correlation, and hierarchical regression. RESULTS: The mean age of the subjects was 72.8 and 57.0% of subjects were female. 41.5% of variance in physical health was explained by nutrition, ADL, IADL, and the number of years attending school. Among them the most important factor was ADL. 13.2% of variance in mental health was explained by the number of family, nutrition, and IADL. Among them the most important factor was nutrition. CONCLUSION: It is necessary to develop supportive interventions for improving the perceived health status of elderly people by considering the most important factors shown in this study.

PURPOSE: Span of Control defines the scope of the managers' responsibilities to manage nursing staff. This study was done to measure span of control of front-line nurse managers (FLNMs) in Korea hospitals resulting in improvement in their work efficiency. METHODS: A sample of 203 FLNMs from five tertiary hospitals was recruited and completed the questionnaires. Data were analyzed using χ²-test, Fisher's exact test, independent t-test, ANOVA, Scheffé, and Pearson correlation coefficient. RESULTS: FLNMs had ‘narrow’ (n=8, 4.3%), ‘appropriate’ (n=161, 87.0%), and ‘wide’ (n=16, 8.6%) span of control. Span of control had significant correlations with the number of nurses (r=.63, p<.001), the number of non-nurses (r=.53, p<.001), units (r=.52, p<.001), staff (r=.83, p<.001), and programs (r=.67, p<.001). CONCLUSION: The research findings indicate that attention should be given to unit complexity, program diversity, total staff, and skills. Moreover, administrators of hospital and nursing departments need to provide systematic support in accordance with FLNMs’ wide span of control.

PURPOSE: This study was done to investigate the types of breastfeeding visits by mothers twenty-four months after birth and to identify the factors that increased breast feeding rates. METHODS: The subjects of this study totaled seven hundred and seventy-four mothers with infants aged 2 years or less who had visited national medical institutions including Sanhujori service facilities, breastfeeding care service facilities, and community health centers. Data was collected from June 22 to July 31, 2009. Data was analyzed using descriptive statistics, chi2 test, ANOVA with a post hoc Scheffe test, and multiple logistic regression. RESULTS: Major findings of this study were significant differences of planned length of breastfeeding and breastfeeding self-efficacy in relation to the differing types of breast feeding community visits by mothers. In multivariate logistic regression, baby's age, exclusive breastfeeding at hospital, utilization of breastfeeding care service facility, planned length of breastfeeding, and breastfeeding self-efficacy were independent predictors of the feeding type. CONCLUSION: In order to increase breastfeeding rates, programs provided by public health care services and medical facilities should start education on breast feeding in the hospital before mothers are discharged and then continue through the use of Sanhujori service facilities and workplace at 3 month and 6 month postpartum.

PURPOSE: The purpose of this study was to identify the influence of nursing organization culture on resilience of new nurses. METHODS: Participants were 1,033 new nurses with careers of less than 12 months and who were from 43 general hospitals located in Seoul, Incheon, other metropolitan cities and provinces in Korea. The data were analyzed using t-test, ANOVA, Pearson correlation coefficient and multiple regression with SPSS/WIN 24.0 program. RESULTS: Relation-oriented culture was scored highest for perception of organizational culture by new nurses (3.35), followed by hierarchy-oriented culture (3.19), innovation-oriented culture (3.12), and task-oriented culture (2.73). The score for resilience of the new nurses was 3.49, and the first subcategories were interpersonal relationship ability 3.66, self-positivity 3.45, and self-control ability 3.36. Relation-oriented culture (β=.30, p < .001) was the most significant factor influencing resilience of new nurses, followed by innovation-oriented culture (β=.14, p=.001), hierarchy-oriented culture (β=.12, p < .001), task-oriented culture (β=−.10, p=.003) in that order (R2(adj. R2)=.16, F=47.04, p < .001). CONCLUSION: Findings show that for improved resilience in new nurses it is necessary to develop relation-oriented culture to provide a cooperative work environment( friendly interpersonal relation and dialogue) for new nurses and to encourage involvement of these members in the hospital culture.

PURPOSE: This study examined the effects of squatting with different foot positions on the muscle activation of the vastus medialis oblique (VMO) and vastus lateralis (VL) muscles in subjects with genu varum. METHODS: Thirty four subjects participated in this study. Surface electromyography was used to measure the muscle activation of the VMO and VL muscles at the knee angles (15°, 60°) at three foot positions (internal rotation, neutral position, external rotation) during squatting. RESULTS: Muscle activation differences at different knee angles and foot positions differed significantly between the VMO and VL muscles in both the varus and normal groups. In addition, there was a significant difference according to the knee angles with the foot in external rotation in the VMO and VL ratio. In the varus group, however, the VMO and VL ratio were significantly different only with the feet in internal rotation. In the muscle activation changes of the knee angle differences in the foot position, there was no significant difference in the varus group, but both the VMO and VL muscles were significant different in the normal group. CONCLUSION: In both groups, regardless of the foot position, muscle activation of the VMO and VL muscles increased with increasing knee flexion angle. In the normal group, when squatting with the feet in external rotation, the VMO and VL muscles activations increased with increasing knee angle. In the varus group, however, the foot position did not affect the VMO or VL muscle activation. This study shows that subjects with genu varum and normal subjects have different VMO and VL muscle activation patterns during squat exercises.

PURPOSE: Parenteral nutrition (PN) is known to provide therapeutic beneficial improvements in malnourished patients for whom enteral nutrition is not feasible. The objective of this study was to investigate the current clinical characteristics and utilization of PN in Korea. METHODS: We analyzed the Health Insurance Review Agency National Inpatients Sample database from 2014 to 2016, which included 13% of all hospitalized patients in Korea. Adult patients aged 20 years or older and receiving premixed multi-chamber bag containing PN were included for this study. Patient characteristics, admission type, primary diagnosis, and hospital demographics were evaluated. SAS version 9.4 was used for data analysis. RESULTS: From 2014 to 2016, 149,504 patients received premixed PN, with 226,281 PN prescriptions being written. The mean patient age was 65.0 years, and 81,876 patients (54.8%) were male. Premixed 3-chamber bag and 2-chamber bag PN solutions were utilized in 131,808 (88.2%) and 32,033 (21.4%) patients, respectively. The number of patients hospitalized through the emergency department were 70,693 (47.3%), whereas 43,125 patients (28.8%) were administered PN in intensive care units. In the adult PN patients, the highest primary diagnosis was malignant neoplasm of the stomach (8,911, 6.0%), followed by organism unspecified pneumonia (7,008, 4.7%), and gastroenteritis and colitis of unspecified origin (6,381, 4.3%). Overall, 34% of adult PN patients were diagnosed with malignancies, the most common being neoplasm of the stomach (17.7%), neoplasm of bronchus/lung (11.2%), neoplasm of colon (11.1%), and neoplasm of liver/intrahepatic bile ducts (10.0%). PN solutions were most frequently administered in the metropolitan area (55.0%) and in hospitals with more than 1,000 beds (23.6%). CONCLUSION: PN was commonly administered in older patients, with primary diagnosis of malignancy in a significant number of cases. This study is the first large-scale description of PN-prescribing patterns in real-world clinical practice in South Korea.

Background: A lineage of Klebsiella pneumoniae that produces carbapenemase-2 (KPC-2), sequence type (ST) 307, emerged in 2017. We analyzed the complete sequences of plasmids from KPC-2-producing K. pneumoniae (KPC-Kp) ST307, investigated the antimicrobial resistance conferred by this strain, and confirmed the horizontal interspecies transmission of KPC- carbapenemase-producing Enterobacteriaceae (CPE) characteristics among Enterobacteriaceae. Methods: We performed antimicrobial susceptibility testing, PCR analysis, multilocus sequence typing, curing tests, and whole-genome sequencing to characterize plasmid-derived KPC-2-producing Enterobacteriaceae clinical isolates. Results: Sequence analysis of KPC-Kp strain ST307 revealed novel plasmid-located virulence factors, including a gene cluster for glycogen synthesis. Three Enterobacteriaceae strains were identified in one patient: K. pneumoniae (CPKp1825), Klebsiella aerogenes (CPEa1826), and Escherichia coli (CPEc1827). The bla KPC-2 gene from K. pneumoniae ST307 was horizontally transmitted between these strains. The plasmids could be transferred through conjugation, because all three strains of bacteria contained the type IV secretion system, pilus genes, and tra genes for conjugal transfer. The bla KPC-2 gene was located on a truncated Tn4401 transposon. Plasmids containing the bla KPC-2 gene could not be artificially removed; thus, the three strains could not be cured. Conclusions The ease of horizontal transfer of KPC-Kp ST307 carbapenem resistance has serious public health and epidemiological implications. This study provides a better understanding of the genetic characteristics that can contribute to the growth and spread of KPC-Kp ST307, and their association with antimicrobial resistance genes.

Background: The development process of clinical practice guidelines (CPGs) must adhere to development standards and must be supported and steered by a representative and consistent governing body. We aimed to investigate the current status of the most recent CPGs published in Korea through surveys of medical professional societies and literature searches. Methods: We collected CPGs developed in Korea in the past 5 years through several electronic database searches (MEDLINE, Embase, and KoreaMed), hand searches, and surveys of medical society memberships from the Korean Academy Medical Societies. Three authors selected Korean CPGs according to our inclusion/exclusion criteria and extracted data from selected CPGs about general characteristics, characteristics of CPGs for setup, evidence evaluation, and the finalization phase. Results: Out of 2,337 articles searched from various sources and 66 documents collected by survey, 129 guidelines (122 by database searching and 7 by survey) were selected. During the recent 5 years, the yearly numbers of CPGs developed were around 25. A single organization was the most frequent CPG development body (42, 32.6%). The most common development methodologies described in the CPGs included were de novo (53, 41.1%) followed by adaptation (48, 37.2%) and hybrid (4, 3.1%). Systematic literature searching was performed in most of the guidelines (79.8%). The evidence level was reported in 104 guidelines (80.6%).There were 77 guidelines (59.7%) that reported an update plan. Fifty guidelines were published in Korean (41.0%), and 46 guidelines were published in English only (37.7%). Conclusion Among CPGs developed in Korea in the last 5 years, the proportion adhering to CPG development standards has increased, but there is still room for improvement.
