To compensate for limited the satisfaction survey currently conducted by Korea Metrological Administration (KMA), a sentiment analysis via a social networking service (SNS) can be utilized. From 2011 to 2014, with the sentiment analysis, Twitter who had commented 'KMA' had collected, then, using $Na{\ddot{i}}ve$ Bayes classification, we were classified into three sentiments: positive, negative, and neutral sentiments. An additional dictionary was made with morphemes appeared only in the positive, negative, and neutral sentiments of basic $Na{\ddot{i}}ve$ Bayes classification, thus the accuracy of sentiment analysis was improved. As a result, when sentiments were classified with a basic $Na{\ddot{i}}ve$ Bayes classification, the training data were reproduced about 75% accuracy rate. Whereas, when classifying with the additional dictionary, it showed 97% accuracy rate. When using the additional dictionary, sentiments of verification data was classified with about 75% accuracy rate. Lower classification accuracy rate would be improved by not only a qualified dictionary that has increased amount of training data, including diverse keywords related to weather, but continuous update of the dictionary. Meanwhile, contrary to the sentiment analysis based on dictionary definition of individual vocabulary, if sentiments are classified into meaning of sentence, increased rate of negative sentiment and change in satisfaction could be explained. Therefore, the sentiment analysis via SNS would be considered as useful tool for complementing surveys in the future.

The purpose of this study was to investigate levels of vocational identity, adaptation in a nursing school, and nursing student satisfaction with major and clinical practice, to examine their interrelationships, and to investigate predictors affecting the vocational identity of nursing students. The participants were 335 nursing students in D city who were surveyed from October to December 2016 using a self-report questionnaire. The data from 317 participants (response rate 94.6%) were analyzed. There was a statistically significant positive correlation between college adaptation, satisfaction with major, satisfaction with clinical practice, and vocational identity. In the multiple regression analysis, college adaptation, satisfaction with major, and satisfaction with clinical practice were factors significantly associated with the vocational identity. These three factors explained 50.6% of the vocational identity of nursing students. Due to the high turnover rate among new nurses, it is critical that nursing students have a vocational identity as nurses. In order to improve vocational identity, nurse educators should consider helping students to adapt to nursing college, and to become satisfied with major and clinical practice.

Results: The satisfaction rate of the FAS within the ambulance was an average of 2.23, and the compatibility category got an overall average score of 2.26. The lowest ranked criteria in the satisfaction and compatibility factor was the functionality of storage space showing 1.93 and 1.88, respectively. The best position of the paramedic seat was the top side of the patient, near the head, which is suitable for patient assessment and treatment. Conclusion: During patient transportation of 119 EMTs, for efficient work process, a layout design of the FAS should be based on ergonomics that satisfied the performance function.

Purpose: The purpose of this study was to examine the effects of breathing exercises performed using panflutes in elderly patients undergoing spinal surgery. Methods: The study design was a nonequivalent control group non-synchronized pre-post test. The study included 24 patients in both the experimental group and the control group. The experimental group completed a daily breathing exercise regimen using panflutes for 30minutes after meals, whereas the control group was provided standard preoperative education, including breathing exercises using incentive spirometers. After the exercise regimen, breathing exercise compliance, pulmonary infections, and life satisfaction were measured in both groups, and the data were analyzed using the SPSS/WIN program. Results: The compliance rate of breathing exercises was significantly higher in the experimental group. The experimental group presented no pulmonary infections in the later period, whereas the control group presented higher pulmonary infection rates in the same period. In addition, the life satisfaction score in the experimental group significantly increased. Conclusion: The breathing exercise program using panflutes for elderly patients undergoing spinal surgery enhanced their breathing exercise compliance and their daily life satisfaction in addition to reducing their pulmonary infection rates.
