For this study, I conducted a survey investigating current situation, user preference, and field experiment. Hospitals utilizing digital sign systems at least five years were selected, which are connected with visual elements (layout, typo, color) used in waiting areas and elements of the systems (time, video time line). The results obtained from the field survey showed that digital sign systems used the color of typo and background contrasted to one another to increase explicitness and to ensure easy understanding of contents. In addition, the Gothic typo with relatively high legibility was adopted. Time and video timeline, which characterize digital sign systems, showed the advertising screens of the hospitals and the guidance of medical treatment at regular intervals. Moreover, survey results on user satisfaction showed that a majority of respondents indicated they had difficulty in understanding digital information conveyed from digital sign systems due to time setting for rotational speed or the small size of typo although most of the users had previous experience with digital sign systems. The highest proportion of respondents (n=86, 86%) answered that information related to medical departments was what they sought most frequently and that this kind of information should be importantly considered in digital sign systems. For the experiment, new samples with restructured contents of current digital sign systems were created and tested while keeping its design unchanged as well as applying these new samples. Study participants were in their 20s through 50s. When the size of typo was larger under the same conditions for all age groups, study participants found the desired information approximately 3.5 seconds faster. In addition, those in their 20-30s and 40-50s showed the time difference of 4.7 seconds for small typo and 6 seconds for large typo, which suggested that there was a difference by age in the amount of time taken in the experiment to find the desired information from the rotating digital sign system regardless of age and the size of typo.

This study was aimed to identify the level of knowledge and performance on nurses for the prevention of extravasation. Subjects of this study was 293 nurses working at three university hospitals, two general hospitals and one specialized hospital that frequently performed chemotherapy in D city. The highest score for the knowledge of nurses was extravasation drug related that it was $18.50{\pm}2.18$. The knowledge and performance were also higher for nurses with age greater than 50 years and married, with a clinical career of more than 10 years and high regard for extravasation. It is essential to develop other plans that promote the prevention of extravasation and to provide a continuous education for preventing extravasation. Therefore, it is necessary for medical institutes to operate patient safety management teams to develop standardized protocols and educating nurses and related persons.

Purpose: This study aimed to identify the etiology and risk factors of community-acquired pneumonia (CAP) requiring hospitalization in Korean children during the coronavirus disease 2019 (COVID-19) pandemic. Methods: Clinical information of children admitted with CAP to Seoul National University Children's Hospital (SNUCH) between January 1, 2021, and February 28, 2022, was retrospectively collected and analyzed. In addition, the etiologic diagnosis and demographic data of children with CAP who were discharged at the other seven hospitals between January and February 2022 were collected. Pneumonia was diagnosed using strict criteria comprising clinical symptoms, physical examination findings, and chest radiographic findings. Results: Among 91 children hospitalized with CAP at SNUCH during the 14-month period, 68.4% were aged <5 years and 79.1% had underlying diseases. Among the 95 CAP cases, respiratory assistance was required in 70.5%, and the use of a ventilator was required in 20.0%. A total of five patients expired, all of whom were either immunocompromised or had underlying neurological diseases. Neurological diseases and immunosuppression were significantly correlated with respiratory assistance (P=0.003) and death (P=0.014). A total of 55% of the detected respiratory pathogens were viruses, the most common of which was rhinovirus at 35.9%. Among the 169 children hospitalized for CAP at the eight institutions, ≥1 respiratory virus was detected in 92.3%, among which respiratory syncytial virus (79.8%) was the most prevalent. Conclusions: Even during the COVID-19 pandemic, Korean children were hospitalized with CAP caused by seasonal respiratory viral pathogens. Although atypical and pyogenic bacteria were not detected, continuous clinical monitoring and further prospective studies should be conducted.

Purpose: Metabolic syndrome (also known as insulin resistance syndrome) represents a constellation of hypertriglyceridemia, hypertension, impaired glucose tolerance, and obesity. Presently, the influence of various factors on metabolic syndrome was assessed in patients of a university hospital comprehensive medical examination center. Methods: Age, sex, blood pressure, height, weight, triglyceride level, high-density lipoprotein cholesterol, and glucose levels were measured in 67 people (37 males and 30 females). These factors were correlated with tobacco use, alcohol consumption, and exercise habits. Metabolic syndrome and abdominal obesity were assessed according to NCEP-ATP III criteria and the Asia-Pacific guidelines (male obesity defined as a waist circumference exceeding 90 cm), respectively. Data was analyzed using t-test, 2-test, and logistic regression. Results: Respective percentages were: tobacco use (14.9% of the 67 people), no tobacco use (85.1%), alcohol consumption (62.7%), no alcohol consumption (37.3%), regular exercise (25.4%), no regular exercise (74.6%). Logistic regression analysis revealed a gender-related odds ratio of 2.3 for metabolic syndrome and no exercise. Conclusions: Weight reduction and physical exercise may decrease the prevalence of metabolic syndrome. Early identification of metabolic syndrome and risk factor modification is prudent in cases of obesity, diabetes, hyperlipidemia, and hypertension.

In this paper, university hospitals, general hospitals/hospitals, private clinics, Chinese medicine hospitals and clinics in Seoul. Metropolitan Inchon, Kyunggi-do were probed to find out how the variables of service task factor are related to customer satisfaction, and to find out the determinants of medical service task(tangible quality, flexibility, cost, time and managerial skills), and anticipation factors, and respective items of customer satisfaction through statistical analysis. The meaning of the above mentioned findings should be carefully understood and construed due to the following problems. Because the factors why patients select hospitals were measured limitedly. it cannot show everything I intended to suggest. Especially due to the insufficient number if items. customer satisfaction variables are too limited. Reflecting the developing changes in various medical environments, hospitals could meet the objective of maintenance and prosperity only by facing the competition effectively and satisfying patients. Also hospitals should pursue patient-oriented service management. In other words, a strategic management of service task factors is needed. Based on this paper's research. a further study should be conducted continuously in order to give customers more satisfaction.

Purpose: The purpose of this study was to identify and understand the self-directed learning patterns of nurses. Q methodology was used to collect the data. Method: For the research method, 43 Q-statements were collected through individual interviews and a review of related literature. The 43 Q-statements were classified by the 34 participants in the study and the data was analyzed by the PC-QUANL program with principal component analysis. Result: There were 4 different patterns of self-directed learning classified as follows : Nurses in Type I the Future Provision Type, studied to promote their own professional development and leadership qualities for the future. Nurses in Type II, the Learning Passion Type, enjoyed learning something new and had a strong learning desire. Nurses in Type III, the Self-reflective Type, continuously evaluated self and their own practice by introspection. Nurses in Type IV, the Accompanying Companion Type, studies with companion support and maintained a collaborative relationship rather than competing with each other. Conclusion: This study explains and allows us to understand self-directed learning in nurses. Thus this study will contribute to building a theoretical base for the development of a self-directed learning model in nursing practice.

Purpose : The purpose of this study was to identify factors influencing the professional self-concept of nurses working in intensive care units (ICUs). Methods : Data were collected from July 1 to August 15, 2014. The subjects were 206 ICU nurses working in four university hospitals in B and U cities, Korea. Their professional self-concept was measured using Arthur's Scale revised by Yoon (2012), and professional quality of life (QOL) was measured using Pro QOL Korean Ver. 5 developed by Stamm (2010). Data were analyzed with SPSS Ver. 18, using a t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis. Results : Professional self-concept was significantly correlated with compassion satisfaction (r=.61, p<.001), and burn out (r=-.57, p<.001). The factors influencing professional self-concept were compassion satisfaction (${\beta}=.46$, p<.001), burn out (${\beta}=-.27$, p<.001), and education level (${\beta}=.14$, p =.014). The explanatory power of this model was 46.5%. Conclusion : The results suggest that the influencing factors found in this study should be considered when planning nursing intervention programs for improving the professional self-concept of ICU nurses.

Purpose: The purpose of this study was to investigate pediatric nurse parent partnership and factors associated with this partnership. Methods: A survey was conducted with 158 nurses working in pediatric practice at one of 7 hospitals in Seoul, Incheon, and Chungcheongbuk Province. Data were collected from September to December 2013, and analyzed with SPSS Windows 21.0. Results: In hierarchial multiple regression analysis, self-efficacy (${\beta}$=.19, p=.016), clinical decision making (${\beta}$=.15, p=.046), and empowerment (${\beta}$=.29, p=.001) were associated with pediatric nurse parent partnership, after adjusting for marital status, children, education, position and satisfaction with work unit. These factors accounted for 44.0% of the variance in the pediatric nurse parent relationship. Conclusion: These results suggest that pediatric nurse parent partnership could be influenced by the predictors. Ultimately, intervention programs focusing on these factors should be effective in helping pediatric nurses improve partnership with parents.
