Background: The use of indwelling central venous access devices (CVADs) in children can result in complications such as infection, occlusion, and dislodgement. Purpose: To evaluate whether reinforcing CVAD care bundles by using a regular direct feedback system could reduce such complications in children. Methods: The intervention in this retrospective interrupted time-series study was initiated in January 2019. The study was divided into the preintervention (October-December 2018), 3-month postintervention (January-March 2019), and 6-month postintervention (April-June 2019) phases. Risk difference and Poisson regression analyses were used to illustrate the effectiveness of the intervention. Results: The hospital-wide central line-related bloodstream infection rate decreased from 10.0/1,000 catheter-days to 4.5/1,000 catheter-days at 3-month postintervention (P=0.39) and to 1.4/1,000 catheter-days at 6-month postintervention (P=0.047). The central line occlusion rate significantly decreased from 30% to 12.8% (P=0.04) and 8.3% (P=0.002) at 3 and 6 months, respectively. Approximately 7% of CVADs became dislodged during the preintervention phase versus 8.5% (P=0.364) and 3.3% (P=0.378) at 3 and 6 months, respectively. Conclusion: Reinforcing CVAD care bundles with direct feedback could significantly decrease CVAD-associated complications in terms of infection at 6-month postintervention, and occlusion at 3- and 6-month postintervention. Thus, reinforcement and regular direct feedback might improve care quality in children with CVADs.

Detecting cracks on a concrete structure is crucial for structural maintenance, a crack being an indicator of possible damage. Conventional crack detection methods which include visual inspection and non-destructive equipment, are typically limited to a small region and require time-consuming processes. Recently, to reduce the human intervention in the inspections, various researchers have sought computer vision-based crack analyses: One class is filter-based methods, which effectively transforms the image to detect crack edges. The other class is using deep-learning algorithms. For example, convolutional neural networks have shown high precision in identifying cracks in an image. However, when the objective is to classify not only the existence of crack but also the types of cracks, only a few studies have been reported, limiting their practical use. Thus, the presented study develops an image processing procedure that detects cracks and classifies crack types; whether the image contains a crazing-type, single crack, or multiple cracks. The properties and steps in the algorithm have been developed using field-obtained images. Subsequently, the algorithm is validated from additional 227 images obtained from an open database. For test datasets, the proposed algorithm showed accuracy of 92.8% in average. In summary, the developed algorithm can precisely classify crazing-type images, while some single crack images may misclassify into multiple cracks, yielding conservative results. As a result, the successful results of the presented study show potentials of using vision-based technologies for providing crack information with reduced human intervention.

Nursing is a discipline that helps to understand human being, to mitigate pains in life by promoting and recovering health, and to study the basic principles in sustaining and preserving life. To understand man and thus to nurse, it is essential to take the way of life of the specific person, his/her ideas, and natural environment into consideration. This means, the temperament, geography, environment and society peculiar to Korea have formed its own culture distinguished from those of other people. Thoughts and philosophy develop as a products of the specific culture and society. Therefore, accurate understanding of the concepts of nursing in the traditional thoughts and philosophy is indispensible to define Korean nursing. Modern Korean nursing at first rooted in the westernized nursing and western nursing intervention has been applied ever since its introduction in the late 19th century under the paradigm of western natural science. However, Koreans in the past made use of alternative therapy which put its emphasis on the organic and holistic view of life as well as a means for traditional medicine and nursing. This alternative therapy has been largely ignored since the introduction of western medical science, and was considered something used only by the aged or the uneducated. Moreover, Health concerned practices and customary traditional therapy have been discarded in the clinical medicine as "unscientific" or "unsystematic". As described above, it is true that Korean nursing has developed in the quantitative aspect only adhering to western nursing intervention. Now it is the time to stop to hold ourself and to look back our past. To find and develop the originality of Korean nursing to cope with the globalization, it is necessary to rediscover nursing (alternative) therapy in Korean culture ignored so far. For this purpose, this study examines the oriental philosophy to explore alternative nursing theory now under development. Also it aims to present ways to apply alternative therapy to nursing education, research and clinical practices and ultimately to show the desirable direction of the nursing to go in the future. Yangsaeng theory of Taoism and Yin-yang, Oh-hang(five elements) and khi theory in Dongeuibogam which gave enormous influences on Korean medical culture and treatment together with Sahsang(four temperaments) emphasized in Dongeuisusebowon will be examined as conceptual framework. Concepts of nursing are categorized into views on each the universe, the human being and nursing. Views on human being is classified into subcategories of body, life, health, and disease. Also it emphasizes the necessity of including alternative therapy in nursing intervention. Views on the universe is classified into yin-yang, khi, and temperament. Nursing will be available anywhere and easily accessible with this new nursing intervention. Trying to give a new thoughts to all those traditional concepts and alternative therapy, this article suggests the necessity of developing original Korean nursing theory and nursing intervention.

Objectives: The purpose of this retrospective study was to evaluate the variables associated with length of stay (LOS), hospital costs, intensive care unit (ICU) use, and treatment outcomes in patients hospitalized for maxillofacial infections at a tertiary medical center in South Korea. Materials and Methods: A retrospective chart review was conducted for patients admitted for treatment of maxillofacial infections at Dankook University Hospital from January 1, 2011 through September 30, 2020. A total of 390 patient charts were reviewed and included in the final statistical analyses. Results: Average LOS and hospital bill per patient of this study was 11.47 days, and ₩4,710,017.25 ($4,216.67), respectively. Of the 390 subjects, 97.3% were discharged routinely following complete recovery, 1.0% expired following treatment, and 0.8% were transferred to another hospital. In multivariate linear regression analyses to determine variables associated with LOS, admission year, infection side, Flynn score, deep neck infection, cardiovascular disease, admission C-reactive protein (CRP) and glucose levels, number and length of surgical interventions, tracheostomy, time elapsed from admission to first surgery, and length of ICU stay accounted for 85.8% of the variation. With regard to the total hospital bill, significantly associated variables were age, type of insurance, Flynn score, number of comorbidities, admission CRP, white blood cell, and glucose levels, admission temperature, peak temperature, surgical intervention, the length, type, and location of surgery, tracheostomy, time elapsed from admission to first surgery, and length of ICU use, which accounted for 90.4% of the variation. Age and ICU use were the only variables significantly associated with unfavorable discharge outcomes in multivariate logistic regression analysis. Conclusion: For successful and cost-effective management of maxillofacial infections, clinicians to be vigilant about the decision to admit patients with maxillofacial infections, perform appropriate surgery at an adequate time, and admit them to the ICU.

Background: Arthroscopic surgical repair is a better intervention than non-operative (conservative) treatment for patients with shoulder dislocations. This systematic review determined the numbers-needed-to-treat (NNT) and relative risk reduction (RRR) associated with arthroscopic surgical repair versus non-operative treatment in reducing recurrence rates among patients with first-time traumatic anterior shoulder dislocations. Methods: We searched Google Scholar, MEDLINE, SPORTDiscus, and CINAHL from inception in 2015. All articles had to compare arthroscopic surgical repair and non-operative treatment and be written in English. We used the total number of subjects and the number of recurrent dislocations within each treatment to calculate the NNT and RRR for each study and the pooled data. Results: Six articles were selected and all clearly demonstrated that the arthroscopic surgical repair was more effective than non-operative treatment in reducing the recurrence episodes. The pooled NNT was 1.76 (95% confidence interval [CI]=NNT to benefit 1.50-2.13) and the pooled RRR was 86.0% (95% CI=77.0%-92.0%) among individuals who underwent arthroscopic repair. The average follow-up time was 56 months. Conclusions: A Strength of Recommendation Taxonomy level of evidence of 1 with a grade A recommendation supports the use of arthroscopic surgical repair over non-operative treatment in prevention of first-time traumatic anterior shoulder dislocations. We suggest that sports medicine practitioners consider the patients' age, occupation, and physical activity level when making a clinical decision.
