Purpose: This study aims to investigate the relationships between knowledge on advance directive, attitudes towards the withdrawal of life-sustaining treatment and quality of life among hemodialysis patients. Methods: A descriptive correlational study was conducted with 103 hemodialysis patients. Data were collected using a structured questionnaire from May to September of 2016, and analysed by using descriptive statistics, t-test, ANOVA and Pearson correlation coefficient. Results: The participants' knowledge level on advance directive was $5.47{\pm}2.08$ out of 9, the attitudes towards the withdrawal of life-sustaining treatment was $3.22{\pm}0.49$ out of 5, and the quality of life was $3.35{\pm}0.92$ out of 6. The knowledge on advance directive was positively correlated with attitudes towards the withdrawal of life-sustaining treatment (r=.21, p=.037) and quality of life (r=.21, p=.036). Conclusion: According to the results of this study, the level of knowledge on advance directive is preferred to improve the quality of life of hemodialysis patients. It is needed to support and maintain ongoing education opportunities in order to improve the level of knowledge on advance directive among patients undergoing hemodialysis.

This paper aims at the development of an knowledge base for an electrical fire cause diagnosis system using the entity relation database. The relation database which provides a very simple but powerful way of representing data is widely used. The system focused on database construction and cause diagnosis can diagnose the causes of electrical fires easily and efficiently. In order to store and access to the information concerned with electrical fires, the key index items which identify electrical fires uniquely are derived out. The knowledge base consists of a case base which contains information from the past fires and a rule base with rules from expertise. To implement the knowledge base, Access 2000, one of DB development tools under windows environment and Visual Basic 6.0 are used as a DB building tool. For the reasoning technique, a mixed reasoning approach of a case based inference and a rule based inference has been adopted. Knowledge-based reasoning could present the cause of a newly occurred fire to be diagnosed by searching the knowledge base for reasonable matching. The knowledge-based database has not only searching functions with multiple attributes by using the collected various information(such as fire evidence, structure, and weather of a fire scene), but also more improved diagnosis functions which can be easily wed for the electrical fire cause diagnosis system.

Purpose: The purpose of this study was to provide basic data for the development of health and safety programs by examining child-care teacher's knowledge, self-confidence and practice concerning the health and safety of children under their care. Method: The participants were 72 teachers from 15 child care centers in Seoul City and Chung-Nam Province. Data were collected using self-report questionnaires. Data were analyzed using descriptive statistics, ANOVA and Pearson correlation coefficients with SPSS 12.0 Win program. Results: The mean score for self-confidence was lower than knowledge and practice. Self-confidence score about emergency care for falls, fractures and resuscitation were lowest. For safety knowledge, scores about facility and environment were lowest. For health knowledge, scores about disease and symptoms were lowest. For practice, scores about seat belts and safe furniture arrangement were lowest. Significant correlations were found between practice and self-confidence. There were significant differences in the degree of knowledge according to education, and in practice according to age. Conclusions: Health and safety education programs for child care teachers are necessary for the promotion of knowledge, self-confidence and practice in health and safety. The results suggest that health and safety education program should be provided systematically and continuously for child care teachers.

Purpose: The purpose of this study was to determine the effect of BSE education and practice on knowledge, self efficacy and performance in female nursing students. Method: The subjects consisted of 40 students from 2 nursing colleges. They responded to questionnaires that included knowledge, self-efficacy and performance of BSE within a 3-month interval. The experimental group was subjected to a 90 minute-educational session. Their knowledge of BSE was measured using Choi's tool and self-efficacy was measured using Champion and Scott. Result: Self-efficacy and frequency of BSE performance in the experimental group were significantly higher than those of the control group while BSE knowledge was not significantly different between the two groups. Conclusion: Nursing students don't put their knowledge into practice. This fact suggests that changing a behavior needs something more than knowledge. In this study, the BSE education had an effect on self-efficacy and performance. Therefore, practical education needs to be reinforced for nursing students to perform BSE for their own health and to be able to demonstrate it for clients.

Purpose: This study was done to evaluate the effectiveness of cardiac rehabilitation education individualized to PCI patients in order to improve their knowledge of these diseases and to lessen their anxiety. Method: A Quasi experimental design with non-equivalent control group non-synchronized design was used. The experimental group had the PCI operation for ischemic heart disease and individualized cardiac rehabilitation education and counseling twice for 25 minutes each time using an educational booklet developed by the authors. The effects of the education were analyzed using a knowledge assessment tool, state anxiety inventory and anxiety visual analogue scale. Results: The experimental group who received the individualized cardiac rehabilitation education showed a high level of knowledge about diseases compared to the control group and particularly showed a significant difference in knowledge about the drugs used for treatment. However, no significant difference was observed between the two groups in the level of state anxiety and anxiety visual analogue scale. Conclusion: Individualized cardiac rehabilitation education did not reduce anxiety but it was effective in enhancing the participants' knowledge about the diseases. Thus, it can be utilized effectively in addressing risk factors in ischemic heart diseases by providing education individualized according to patients' demands and knowledge levels.

Purpose: This descriptive study was conducted to identify the level of knowledge of stroke symptoms and risk factors among older adults. Methods: A total of 200 older adults over 65 years of age were conveniently recruited from out patient departments of two hospitals and a health care center from October to November 2008. The level of knowledge was assessed using both open-ended questions and a structured questionnaire based on semi-structured interviews. Data were analyzed by t-tests and ANOVA using the SPSS program. Results: 52.5% of the sample had hypertension and 30% had diabetes. The mean knowledge scores for symptoms and risk factors were $8.4{\pm}3.1$ (out of 15) and $9.5{\pm}3.9$ (out of 16), respectively. The older adults who had lower education, lower family income, and who lived in rural areas were more likely to have less knowledge of stroke symptom and risk factors (p < .05). There was no significant knowledge difference between the older adults who had at least one risk factor and those who had no risk factor for stroke. Conclusions: Educational intervention should be focused on informing older adults who are at risk for stroke about the early symptoms and management of risk factors, especially those who have low education and low social status.

Extant research on firm innovation productivity is limited in measuring the innovation productivity, in which they measured firm innovation productivity by using either inputs or outputs of innovation. The present study complemented the extant research by employing Data Envelopment Analysis (DEA) approach to measure firm innovation productivity. Furthermore, this paper examined the effects of firms' external knowledge search, as one of open innovation practices, on firm innovation productivity, for open innovation activities are regarded as an influencing factor on firm innovation productivity in the previous literatures. Using the data of the Korean Innovation Survey (KIS) of manufacturing industries conducted in 2008, this study developed hypotheses in which we considered not only two dimensions of external knowledge search (breadth and depth) but also two subtypes of external knowledge search (market-driven and science-driven). The results found that searching deeply and market-driven search are positively related to firm innovation productivity, but science-driven search is somewhat negatively related to firm innovation productivity. Furthermore, market-driven search can mitigate the negative effect of science-driven search on innovation productivity.
