This study was conducted to examine the effect of organizational safety culture on radiologists' awareness of patient safety and safety behavior. The study was conducted based on the results of the survey, and the survey was divided into three factors: general characteristics, efforts for patient safety, and patient safety culture. As a result of the study, age, work experience, and work satisfaction were influencing factors in general characteristics, and gender, academic background, and work type were not included as factors affecting differences in patient safety awareness. In efforts for patient safety, hospital support and education, patient safety activities, and how to respond to errors were all influencing factors, especially how to respond to errors were more relevant than other items. The patient safety culture was analyzed on two items: teamwork and open communication, and both items were highly related to radiologists' awareness of patient safety.

This study aimed to investigate the awareness and performance of safety in operating room nurses. There were 161 operating room nurses from eight general hospitals included for analysis in this study. The data were analyzed with t-test, one-way ANOVA, correlation analysis, and Scheffe's test. The results show that their perception of patient safety was 3.33 out of a total of 5 points. Moreover, the score of safety management activity for patients in the operating room was 4.28 out of 5 points. As the perception of patient safety in operating room nurses was significantly correlated with their safety management activities, nurses with higher awareness of patient safety were found to have higher degree of performance of safety management activities. In conclusion, to improve safety management activities, open discussion about patient safety should be encouraged and periodic education regarding patient safety should be implemented for operating room nurses to increase the perception of patient safety.

Purpose: The objectives of this study were to 1) explore nurses' attitudes toward death, coping with death, understanding and performance regarding end-of-life (EOL) care, 2) describe correlations among the above factors, and 3) determine the factors affecting nurses' EOL care performance. Methods: Study participants were 187 nurses stationed at departments that post higher mortality than others such as the oncology department, intensive care unit (ICU) and emergency department (ED). Data were collected from three urban university-affiliated hospitals. Multi-dimensional measure was performed for study instruments such as "attitude toward death", "coping with death" and "understanding and performance regarding EOL care". Data were analyzed by using descriptive statistics, correlation, and multiple regressions. Results: First, nurses showed significantly different attitudes toward death by age, religion, work unit and EOL care education. Younger nurses tend to score low on the understanding of EOL care, and ED nurses' score was lower than their peers at the oncology department and ICU. Second, EOL care performance was positively correlated with attitude toward death (P<0.001), coping with death (P=0.003) and understanding of EOL care (P<0.001). Third, nurses' EOL care performance was affected by work unit (P<0.001) and understanding of EOL care (P<0.001). Conclusion: Because nurses' performance was influenced by their work unit and understanding of EOL care, they should be provided with appropriate training to improve their understanding of death and EOL care according to work unit.

This paper proposes an effective recognition method of VPI patient's speech employing DNN-HMM-based speech recognition system, and evaluates the recognition performance compared to GMM-HMM-based system. The proposed method employs speaker adaptation technique to improve VPI speech recognition. This paper proposes to use simulated VPI speech for generating a prior model for speaker adaptation and selective learning of weight matrices of DNN, in order to effectively utilize the small size of VPI speech for model adaptation. We also apply Linear Input Network (LIN) based model adaptation technique for the DNN model. The proposed speaker adaptation method brings 2.35% improvement in average accuracy compared to GMM-HMM based ASR system. The experimental results demonstrate that the proposed DNN-HMM-based speech recognition system is effective for VPI speech with small-sized speech data, compared to conventional GMM-HMM system.

This study was conducted to examine the oral health awareness, needs of dental treatment and the oral and maxillofacial pains targeting pneumoconiosis patients of care hospitals for the purpose of providing basic data for preparing a plan to improve the oral health of patients plagued with pneumoconiosis. As the subjects of survey, total 120 patients who have agreed to the research among the patients of three care hospitals, were enrolled between March and July in 2015. As the result of the study on the factors that influence the oral health perception, it was verified that the persons of an average monthly income of 2 million won or more, were shown to have significantly better oral health awareness than the subjects of monthly earning of less than 2 million won (p<0.05), thus showing that the oral health awareness by the people of monthly income of more than 2 million won, was 0.77 times higher compared to the others. Therefore, in order to improve the oral health awareness of pneumoconiosis patients, the economic stability of the patients should be taken into account as a priority when examining the oral health policy decisions and it was recommended that the survey and research on the oral health of patients with pneumoconiosis can be done in amore systematic manner.

This study examined the nursing student's preliminary knowledge and awareness of patient's personal information protection. 187 respondents, who were trained in 2 different nursing colleges in Kyungpook province, participated in the survey from May 18 to June 12, 2015. Using the data collected, descriptive statistics, T-test and one-way ANOVA were implemented. As a result, the student nurses, who had heard about the Personal Information Protection Act showed a significantly higher awareness score of patient's personal information protection behavior than those who did not. The respondents educated in personal information protection were reported to have a higher score of awareness about the patient's personal information protection behavior. In this regard, it is vital for university organizers to develop education associated with ethics and information security, which could enhance the perceptions of personal information protection for student nurses before their working career begins.

Purpose: This study is aimed to investigate perceptions of caregivers and medical staff toward do not resuscitate (DNR) and advance directives (AD). Methods: Participants were 141 caregivers and 272 medical staff members from five general hospitals. A questionnaire used for the study consisted of 20 items: 14 about DNR perceptions, three about AD, one each for age, gender and employment. Results: Both medical staff and caregivers strongly recognized the need for DNR and AD, and the level of recognition was higher with medical staff than caregivers (DNR ${\chi}^2=44.56$, P=0.001; AD ${\chi}^2=16.23$, P=0.001). The main reason for the recognition was to alleviate sufferings of patients in the terminal phase. In most cases, DNR and AD were filled out when patients with terminal conditions were admitted, and patients made the decisions by consulting with their guardians. Medical staff better recognized the need and for growing demand for guidelines for the DNR and AD decision making process than caregivers (${\chi}^2=7.41$, P=0.0025). Conclusion: This study showed that patients highly rely on their caregivers when making decisions for DNR and AD. Thus, it is important that patients and caregivers are provided with objective information about the decisions. Since participants' strong support for DNR and AD was mainly aimed at alleviating patients' suffering, further study is needed in the association with hospice care. Medical staff also needs to understand the different views held by caregivers and fully consider the disparity when informing patients/caregivers to make the DNR and AD decisions.
