Purpose: This study was conducted to investigate the correlation among nurses' knowledge, performance, and stress about care for delirium. Methods: The data were collected using the instruments for knowledge about nursing care (50 items), performance (23 items), and stress (20 items). Descriptive statistics and Pearson's correlation coefficient were used to analyze the data of 222 participants. Results: Nursing knowledge were different by clinical experience (F=3.12, p=.016), position at work (t=-2.54, p=.012), experience in caring patients with delirium (t=3.90, p<.001), and conflicts with other disciplines on matters related to delirium (t=4.00, p=.001). The difference in performance were associated with age (F=4.19, p=.001), clinical experience (F=2.67, p=.003), and whether there was a guideline for managing the patients with delirium (t=2.30, p=.022). Stress of nurses was different by whether they had a religion or not (t=-2.41, p=.017). The knowledge of care for delirium had the positive relationship with performance (r=.21, p=.001) and negative relationship with stress (r=-.29, p=.001).

Purpose: This study aimed to identify falls and related risks of hospitalized patients in order to provide an baseline data to develop effective nursing intervention programs for fall prevention. Methods: The data on 120 patients who experienced falls from 2010 to 2013 during their hospitalization were collected from the patient' electronic medical records of an university hospital. Data were analyzed with descriptive statistics using SPSS/WIN 20.0. Results: Over 60% of the patients who experienced falls during their hospitalization was 65 years or older, and most of them had hypertension. Majority of the subjects needed help to perform daily activities (64%) and complained of general weakness (49.2%). Prior to the falls, the patients were taking average 2.52 medications to treat hypertension. The Fall accident was mostly frequently occurred in their hospital room (59.2%), or in bed (44.2%). The patients aged 70 years and older were significantly less alert than younger group, and taking more cardiovascular medications. Most fall risk factors were not significantly different for age, gender, and department category. Conclusion: The study findings suggest the need to emphasize the nurses to be more actively aware of fall risk factors and to provide aggressive interventions for preventing falls in hospitalized patients.

Purpose: This study aims to investigate the fear of falling of stroke patients and identify factors affecting the fear of falling. Method: For basic data, structured questionnaires were used for 137 stroke patients in hospitals in B city sampled for this study from June to August, 2010. Results: A multiple regression analysis used to identify variables affecting the fear of falling of stroke patients indicates that the most affecting variable was activities of daily living (${\beta}$=-.558), followed by self-efficacy of falling (${\beta}$=-.223), primary caregiver (${\beta}$=-.118), perception of health (${\beta}$=-.128) and drunken status (${\beta}$=-.108). Total variance explained by activities of daily living, self-efficacy of falling, the primary caregiver, perception of health and drunken status was 81.2% (F=70.845, $R^2$=.812). Conclusion: As discussed above, the factors significantly affecting the fear of falling in stroke patients were activities of daily living and self-efficacy of falling. Therefore, in order to reduce fear of falling of stroke patients and prevent falling, it is suggested that programs should be developed that will improve self-efficacy of falling and daily living activities.

This study was conducted to compare the cleansing effect of various irrigants and the function of the quantity of irrigants in apical region. One hundred sixty single rooted teeth were divided into four groups and fourty teeth in each group were individually enlarged and irrigated with each of four irrigants as they would be during clinical condition. The four tested irrigants were Normal saline solution, 3.5% NaOCl, 15% EDTA, and 50% Citric acid. In each group, twenty teeth were flushed with 2cc of each irrigant and another twenty teeth with 5cc of same irrigant after use of each instrument. After final flush and dry, the roots were split longitudinally and the degree of cleansing at apical portion were evaluated under Stereoscope by three observers. The typical specimens of each group were also examined under Scanning electron microscope. The results were as follows. 1. There were no significant difference of cleansing effect among the tested irrigants. 2. 5cc flushed groups have more samples that have high degree of cleansing than 2cc flushed groups. 3. The canals irrigated with 2cc showed the presence of many dentin chips, tissue debris and smeared layer, whereas the 5cc groups revealed relatively clean canal surface and less smeared layer under Scanning electron microscope. 4. The teeth flushed with 5cc of EDTA and with 5cc of Citric acid showed the most clean canal surface at Scanning fictures.
