Purpose: The aim of this study was to explore characteristics of and risk factors for accidental inpatient falls. Methods: Participants were classified as fallers or non-fallers based on the fall history of inpatients in a tertiary hospital in Seoul between June 2014 and May 2015. Data on falls were obtained from the fall report forms and data on risk factors were obtained from the electronic nursing records. Characteristics of fallers and non-fallers were analyzed using descriptive statistics. Risk factors for falls were identified using univariate analyses and logistic regression analysis. Results: Average length of stay prior to the fall was 21.52 days and average age of fallers was 61.37 years. Most falls occurred during the night shifts and in the bedroom and were due to sudden leg weakness during ambulation. It was found that gender, BMI, physical problems such elimination, gait, vision and hearing and medications such as sleeping pills, antiarrhythmics, vasodilators, and muscle relaxant were statistically significant factors affecting falls. Conclusion: The findings show that there are significant risk factors such as BMI and history of surgery which are not part of fall assessment tools. There are also items on fall assessment tools which are not found to be significant such as mental status, emotional unstability, dizziness, and impairment of urination. Therefore, these various risk factors should be examined in the fall risk assessments and these risk factors should be considered in the development of fall assessment tools.

Purpose: Ineffective communication between healthcare professionals leads to medical errors and puts patients at risk of harm. The aim of this study was to examine the effects of interdisciplinary communication training in simulated settings on self-confidence in communication, observed communication behavior, and technical skill performances of nursing students. Methods: A repeated measures design with one group was conducted. Data was collected from 92 nursing students through a self-administered questionnaire and an observed behavior checklist. Data analysis was performed using descriptive statistics, a paired t-test, the Wilcoxon signed rank test, the Friedmann test, a Repeated Measures ANOVA, and the Spearman correlation coefficient. Results: Self-confidence in communication, observed Identification-Situation-Background-Assessment-Recommendation-Read Back communication behavior, and technical skill performances of nursing students were significantly improved. In observed communication behavior, the performance of Assessment and Read Back communication significantly improved. However, communication of Background, Assessment, and Recommendation did not improve to a satisfactory level. Observed communication behavior was not correlated with the overall technical skill performance. Conclusion: These results indicate that interdisciplinary communication training in simulated settings was effective in improving nursing students' confidence and communication skills with physicians. Longitudinal studies with larger samples are recommended in order to verify the effects of interdisciplinary communication training on clinical outcomes as well as communication competence.

Purpose: The present study confirms the content validity and understanding level of the questions of the Korean version of caries management by risk assessment (CAMBRA). Methods: To develop the Korean version of CAMBRA for children aged 0-5 years, a series of steps were followed: first, translation and reverse-translation processes were conducted by an expert committee. To establish content validity, CAMBRA was modified to adapt to the conditions in Korea by 17 dental hygiene professionals with a master's or a higher degree. The responses were analyzed using analysis of frequency and descriptive statistics. Content validity was verified by calculating the content validity index (CVI). The survey was administered to 64 mothers and caregivers to assess the understanding level of questions of the Korean version of CAMBRA. Results: Content validity of each of the items showed an S-CVI/AVE value of 0.79, but the content validities varied from 0.63 to 1.0. The understanding level of each question was between 3.56 and 4.46, thus showing favorable results. Conclusion: It was concluded that the test items verified for content validity were suitable for assessing caries risk for children of ages 0-5 years. This study would contribute to improving children's oral health and disease prevention by providing timely intervention.

In abrupt fire disturbances, high quality images suitable for wildfire damage assessment can be difficult to acquire. Quantifying wildfire burn area and severity are essential measures for quick short-term disaster response and efficient long-term disaster restoration. Planetscope (PS) imagery offers 3 m spatial and daily temporal resolution, which can overcome the spatio-temporal resolution tradeoff of conventional satellites, albeit at the cost of spectral resolution. This study investigated the potential of augmenting PS imagery by integrating the spectral information from Sentinel-2 (S2) differenced Normalized Burn Ratio (dNBR) to PS differenced Normalized Difference Vegetation Index (dNDVI) using histogram matching,specifically for wildfire burn area and severity assessment of the Okgye wildfire which occurred on April 4th, 2019. Due to the difficulty in acquiring reference data, the results of the study were compared to the wildfire burn area reported by Ministry of the Interior and Safety. The burn area estimates from this study demonstrated that the histogram-matched (HM) PS dNDVI image produced more accurate burn area estimates and more descriptive burn severity intervals in contrast to conventional methods using S2. The HM PS dNDVI image returned an error of only 0.691% whereas the S2 dNDVI and dNBR images overestimated the wildfire burn area by 5.32% and 106%, respectively. These improvements using PS were largely due to the higher spatial resolution, allowing for the detection of sparsely distributed patches of land and narrow roads, which were indistinguishable using S2 dNBR. In addition, the integration of spectral information from S2 in the PS image resolved saturation effects in areas of low and high burn severity.

Purpose: The purpose of this study was to identify the correlation of critical thinking disposition and problem solving process, and the simulation- based assessment of clinical competence based on a survey of college nursing students. Methods: In this descriptive correlation study, data for 214 nursing students were analyzed using t-test and Pearson correlation coefficients. Results: Critical thinking disposition, problem solving process, and simulation-based assessment of clinical competence averaged $3.76{\pm}0.46$ (out of 5), $3.67{\pm}0.47$ (5), and $1.51{\pm}0.17$ (2), respectively. A significant difference in scores for simulation-based assessment of clinical competence was found between the high-scoring group and low-scoring group in critical thinking disposition. A significant positive correlation was found between critical thinking disposition and nursing assessment, a sub-domain of clinical competence. Conclusion: The results suggest that success in simulation-based learning requires critical thinking disposition in the nursing students, and their critical thinking disposition plays a positive role in nursing assessment, which evaluates the patient's status in a complex situation. Simulation-based learning programs help assess the students' levels in their clinical judgement and performance, and identify their strengths and weaknesses so that the instructor can evaluate and improve the current teaching method.

Objectives: The purpose of the study was to investigate factors affecting the assessment of objective and subjective masticatory ability in the elderly, and to evaluate masticatory ability assessment more accurately. Methods: A total of 112 participants were recruited after oral examination in senior citizen welfare facilities. The participants' masticatory ability was evaluated objectively (Mixing ability index; MAI), and subjectively (Key food intake ability; KFIA). Participants' general characteristics and oral health-related variables were also recorded. Based on masticatory ability assessment, participants were classified as either high or low. IBM SPSS Statistics Ver.23.0 was used for all analyses, including descriptive statistics, Chi-square test, Mann-Whitney U test, Spearman rank correlation, and Logistic regression analysis. Results: Higher masticatory ability was positively correlated with higher scores on MAI and KFIA. Additionally, there was a significant positive correlation between MAI and KFIA. When analyzing factors affecting objective and subjective masticatory ability assessments, Functional tooth units (FTUs) were revealed as a related factor. In subjective masticatory ability assessment, oral moisture, difficulty in chewing, and the Geriatric Oral Health Assessment Index (GOHAI) were also influential factors. Conclusions: In order to accurately assess masticatory ability, it is necessary to use both objective and subjective measures. Additionally, to improve the masticatory ability in the elderly, treatment should be provided to improve overall oral health and satisfaction.

Data were collected from 120 teachers at 67 childcare centers in Seoul and Kyunggi-Do. The Assessment Scale for Day Care Programs(Rhee et ai., 2003) was used to observe teachers' interaction behaviors. Subjects responded to the teachers' job stress scale developed by the author and a modified version of teachers' efficacy scale based on the Science Teaching Efficacy Belief Instrument(Enochs & Riggs, 1990). Data were analyzed with descriptive statistics, Pearson correlations, and hierarchical regressions. Results showed that quality of teachers' interaction behaviors correlated negatively with teachers' job stress, and positively with teachers' personal efficacy; teachers' belief of efficacy moderated the relationship between job stress and teachers' interaction behaviors.
