We predict the mortality of the elderly patients visiting the emergency department who are over 65 years old using Feed Forward Neural Network (FFNN) and Convolutional Neural Network (CNN) respectively. Medical data consist of 99 features including basic information such as sex, age, temperature, and heart rate as well as past history, various blood tests and culture tests, and etc. Among these, we used random forest to select features by measuring the importance of features in the prediction of mortality. As a result, using the top 80 features with high importance is best in the mortality prediction. The performance of the FFNN and CNN is compared by using the selected features for training each neural network. To train CNN with images, we convert medical data to fixed size images. We acquire better results with CNN than with FFNN. With CNN for mortality prediction, F1 score and the AUC for test data are 56.9 and 92.1 respectively.

This study distinguishes the aging population as young-old and old-old women. It examines the difference of each variable between young-old and old-old women. Also, it examines the effect of physical, psychological, social, economic and environmental factors on the quality of life for older adults in both groups and compares the effects on the quality of life between both groups. The sample of this study is collected from Daegu and Kyungbuk province and the sample size of this study is 310. As statistical method, t-test, $X^2$ and hierarchical multiple regressions are used. As demographic factors, age, marital status, income and education are controlled. The research results show that marriage, perceived health, self-esteem and social support are important factors of affecting on the quality of life for both groups. However, for young-old group, the perceived economic hardship and the receipt of social welfare affect negatively and social participation affects positively on the quality of life. On the other hand, for old-old group, informative social role affects positively and social participation affects on the quality of life negatively.

As the global population becomes aging, the demand for health services for the elderly is expected to increase. In particular, The elderly visiting the emergency department sometimes have complex medical, social, and physical problems, such as having a variety of illnesses or complaints of unusual symptoms. The proposed system is designed to predict the mortality of the elderly patients who are over 65 years old and have admitted the emergency department. For mortality prediction, we compare the support vector machines and Feed Forward Neural Network (FFNN) trained with medical data such as age, sex, blood pressure, body temperature, etc. The results of the FFNN with a hidden layer are best in the mortality prediction, and F1 score and the AUC is 52.0%, 88.6% respectively. If we improve the performance of the proposed system by extracting better medical features, we will be able to provide better medical services through an effective and quick allocation of medical resources for the elderly patients visiting the emergency department.

Purpose: Blood culture is the most important tool for detecting bacteremia in children with fever. However, blood culture contamination rates range from 0.6% to 6.0% in adults; rates for young children have been considered higher than these, although data are limited, especially in Korea. This study determined the contamination rate and risk factors in pediatric patients visiting the emergency room (ER) or being admitted to the ward. Methods: We conducted a retrospective chart review of blood cultures obtained from children who visited Yonsei Severance Hospital, Korea between 2006 and 2010. Positive blood cultures were labeled as true bacteremia or contamination according to Centers for Disease Control and Prevention/National Healthcare Safety Network definitions for laboratory-confirmed bloodstream infection, after exclusion of cultures drawn from preexisting central lines only. Results: Among 40,542 blood cultures, 610 were positive, of which 479 were contaminations and 131 were true bacteremia (overall contamination rate, 1.18%). The contamination rate in the ER was significantly higher than in the ward (1.32% vs. 0.66%, P<0.001). The rate was higher in younger children (2.07%, 0.94%, and 0.61% in children aged <1 year, 1-6 years, and >6 years, respectively). Conclusion: Overall, contamination rates were higher in younger children than in older children, given the difficulty of performing blood sampling in younger children. The contamination rates from the ER were higher than those from the ward, not accounted for only by overcrowding and lack of experience among personnel collecting samples. Further study to investigate other factors affecting contamination should be required.

by providing objective information regarding medical radiation for elementary, middle, and high school students in Korea, who are expected to have a high ripple effect in education, and by analyzing behavioral changes in the selection of medical radiation, this study aimed to deduce the basis for educational intervention. The tools used in the study were a questionnaire, including questions about perception, knowledge, attitude, and behavior toward medical radiation; video and Power-point materials for the lesson; simulated radiation diagnosis selection form; and radiation treatment selection form to find out about behavior. A post-test demonstrated that the objective knowledge about medical radiation of all the students turned out to be significantly higher (p<0.000) after the lesson compared to before the lesson. However, there were no statistically significant behavioral changes. Rather, for high school students, the behavior of selecting medical radiography and treatment was significantly lower (p<0.000) after the lesson. For the more impressionable children in the lower grades, the lesson must not only provide an opportunity to understand and pay attention to diverse viewpoints, but also encourage them to make ethical decisions based on value. Since it can be predicted that attitude or behavioral changes through education or publicity can be expected from adults older than high school students, issues regarding dangers like radiation exposure must be treated as an issue of value judgment predicated on multifaceted considerations.

Background: Epidermoid cysts are benign tumors derived from the infundibular portion of hair follicles and thus have a flattened surface epithelium and keratohyaline granules. They can occur at any age but are most frequently reported in adults, and more often occur in men than women. Most epidermoid cyst operations are performed for cosmetic purposes, or to relieve inflammation. The definitive treatment is complete excision or destruction of the cyst. The aim of this study was to improve understanding of epidermoid cysts. Methods: We analyzed 432 cases of epidermoid cyst in 398 patients that underwent complete excision and biopsy between April 2001 and March 2020, according to patient age, patient gender, and lesion location. Results: From all epidermoid cyst excisions performed, 17.6% were for patients in their 40s and 50s, 16.8% for those in their 20s, 16.1% for those in their 30s, 14.6% for those aged 60 or older, 5.0% for teenagers, and 0.5% for those under 10 years. Cases of epidermoid cysts occurred at a men-to-women ratio of about 3:2, with 59.5% of cases in men and 40.5% in women. By lesion location, 65.0% of cases were on the face, 10.9% on the trunk, 7.9% on the scalp, 7.9% on the neck, 4.3% on lower extremities, 3.9% on upper extremities, and 0.2% on genitalia. On the face, 20.8% of cases were on the cheek, 12.7% on the periauricular area, 10.9% on the periorbital area, 6.0% on the frontal area, 5.6% on the mental area, 3.7% on the perioral area, 2.8% on the nasal area, and 2.5% on the temporal area. Conclusion: The proportion of women with epidermoid cysts was higher in our study than in previous studies. Moreover, the results showed that surgery has been on the rise in recent years, with facial surgery being the most common.

Purpose: This study aimed to describe Korean nursing home nurses' perceptions on dysphagia management and their working experiences of older adults with dysphagia. Methods: Using a purposive sampling design, 23 eligible nurses were interviewed as four focus groups from 4 facilities out of nursing homes. The qualitative data from focus group interviews were analyzed using thematic analysis to classify common themes into larger categories. Results: Two main themes on the attributes of caring nursing home residents with dysphagia were 'Need for nursing resources' and 'Need for support'. In addition, four subthemes emerged as a result of analysis: 'need for nursing protocols for assessing and managing dysphagia', 'need for emergency care skills of nurses and nurse assistants', 'need for prompt and accurate management by cooperation of physicians and therapists', and 'need for partnership upon comprehension of visiting family members concerning dysphagia'. Conclusion: Nursing home nurses fully recognized the importance of dysphagia management; however, they experienced substantial barriers due to lack of adequate nursing protocols or partnership with family caregivers, insufficient training for emergency care, and deficient support from medical staff. Development of nursing guidelines tailored to the nursing home context and based on partnership among medical experts and family caregivers is needed.

Purpose: This study aimed to identify the effect of integrated nursing using cognicise and neurofeedback on cognition and α waves among elderly individuals. Methods: This quasi-experimental single group pretest-posttest study included 29 Korean adults aged 65 years or older who participated at a senior welfare center in Y city from February to May 2019. Each integrated nursing session consisted of cognicise (10 minutes) and neurofeedback (20 minutes). Subjects participated twice a week for 10 weeks. Structured questionnaires to assess participants' general characteristics and the Korean version of the Mini-Mental Status Examination for Dementia Screening (K-MMSE-DS) were applied. Alpha waves were measured using BrainMaster. Results: Following the integrated nursing program, alpha waves improved in F3 (t=2.41, p=.023), C3 (t=3.00, p=.006), C4 (t=2.60, p=.015), P3 (t=2.43, p=.022), O1 (t=2.30, p=.029), T3 (t=3.05, p=.005), T4 (t=2.28, p=.030), T5 (t=2.91, p=.007), Fz (t=2.30, p=.029), Cz (t=2.73, p=.011), and Pz (t=2.23, p=.034). Most subjects experienced improvement in concentration after participating in the intervention. Conclusion: This study provides evidence for the use of a neuroscientific approach including brain wave measurement to improve cognitive health among community-living elderly people.
