The purpose of this study is to investigate the level of correctness accounting information with the two alternative forms of presenting information outputs. Specifically two different methods of presenting accounting information, the table form and the graphical form were employed to test the level of correctness of the accounting information user's decision making. Using college students as a surrogate decision maker, this research have found that there is no statistically significant difference in the correctness of decision making between the two groups, one group using the table form of accounting information and another group using the graphical form of accounting information.

In this paper, we define generalized induced linguistic aggregation operator called generalized induced linguistic ordered weighted harmonic mean(GILOWHM) operator. Each object processed by this operator consists of three components, where the first component represents the importance degree or character of the second component, and the second component isused to induce an ordering, through the first component, over the third components which are linguistic variables and then aggregated. It is shown that the induced linguistic ordered weighted harmonic mean(ILOWHM) operator and linguistic ordered weighted harmonic mean(LOWHM) operator are the special cases of the GILOWHM operator. Based on the GILOWHM and LWHM operators, we develop an approach to group decision making with linguistic preference relations. Finally, a numerical example is used to illustrate the applicability of the proposed approach.

As the number of deteriorated infrastructures increases, research on decision-making methods for efficient budget allocation is required. Thus, this study considered the application of utility theory for asset management of deteriorated infrastructure. In decision-making, methods that enable quantitative measurement were proposed, attributing the aging, economic feasibility, and ripple effects. This study is meaningful as a basic study of decision-making methods, and we will conduct research applied to case studies in the future.

This study examined the effects of courage on happiness and the mediating effects of the decision making ability on the relationship between courage and happiness. The courage Inventory for Young Children (Park & Lee, 2011), The Children's decision making ability Scale (Park, 2012) and the happiness Questionnaire (Kim, 2008) were administered to 220 young children (112 boys, 108 girls, 5 year of age). The collected data were analyzed by descriptive statistics, Pearson's correlation analysis, multiple regression analysis, and a sobel test using the computer program, SPSS/PC 21.0. The results were as follows. First, there were significant positive relationships among courage, decision making ability, and happiness. Second, courage was an important factor in predicting the happiness of young children, and the decision making ability had mediating effects on the relationship between courage and happiness.

In this research, in order to investigate the principles for the development of mathematics textbook for decision-making based on storytelling, we conceptualized the educational meaning of decision-making and specified the principles and the methods for the textbook based on decision-making. We illustrated the principles and the methods by the cases from the model textbook for the conditional probability that we have developed. We discussed the implication for the future development and implementation of mathematics textbook for decision-making based on storytelling.

Fuzzy number intuitionistic fuzzy sets (FNIFSs), each of which is characterized by a membership function and a non-membership function whose values are trigonometric fuzzy number rather than exact numbers, are a very useful means to describe the decision information in the process of decision making. Wang [10] developed some arithmetic aggregation operators, such as the fuzzy number intuitionistic fuzzy weighted averaging (FIFWA) operator, the fuzzy number intuitionistic fuzzy ordered weighted averaging (FIFOWA) operator and the fuzzy number intuitionistic fuzzy hybrid aggregation (FIFHA) operator. In this paper, based on the FIFHA operator and the FIFWA operator, we investigate the group decision making problems in which all the information provided by the decision-makers is presented as fuzzy number intuitionistic fuzzy decision matrices where each of the elements is characterized by fuzzy number intuitionistic fuzzy numbers, and the information about attribute weights is partially known. An example is used to illustrate the applicability of the proposed approach.

Purpose: This study was done to develop a realistic clinical case and investigate nurses' decision-making about nurses' ethical dilemmas with physicians in the fields of nursing practice. Methods: Case development and a hypothetical case study were used. Participants were 52 nurses. Data were collected in 2012 and 2013 using an open-ended questionnaire and interviews and analyzed using content analysis and descriptive statistics. Results: Various dilemma situations between nurses and physicians, such as violence, deathbed, medication prescription, and physicians' incapacity unfairness, were suggested. A clinical dilemma case about medication prescription was developed based on nurses' experiences. Nurses' responses to the developed case situation and responses were classified into five types. Various reasons were given for making the decisions and about 56% of the nurses decided to notify their supervisor without deleting nursing records. Conclusion: In this study, a realistic clinical dilemma case was developed, and nurses' ethical decision making was identified. These findings can be used in developing effective strategies for nurses to solve ethical dilemmas and to improve ethical decision-making abilities.

Purpose: The purpose of this study was to explore how knowledge management of hospital and nurses' beliefs and competences on evidence-based practice can affect evidence-based decision making. Methods: In this descriptive study, a total of 184 nurses who were working in the five general hospitals participated. The data were collected through a self-administered questionnaire in September, 2014. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficient, and step-wise multiple regression with SPSS/WIN Statistics 21.0 program. Results: Evidence-based decision making was correlated with EBP beliefs (r=.55, p<.001), EBP competence (r=.57, p<.001), and knowledge management (r=.50, p<.001). Hierarchical regression analysis showed that EBP beliefs (${\beta}=.18$, p=.005), EBP competence (${\beta}=.37$, p<.001), organizational knowledge management (${\beta}=.27$, p<.001) explained 48.6% of evidence based decision making (p<.001). Conclusion: The study results indicated that evidence-based practice competences, organizational knowledge management, and evidence-based practice beliefs were important factors on evidence-based decision making. In order to improve evidence-based practice among nurses through organizational knowledge management, EBP beliefs and competence at individual level need to be considered and incorporated into any systemic training of EBP.

The purpose of this study was to identify the effects of wives' economic contributions and sex-role attitudes on couples' decision-making for use in family education and to improve stable couple relationships. This study targeted 286 married women who have a child or children. The main results of this study indicate that almost half of the participants showed that their couple decision-making, economic resource contributions and sex-role attitudes were husband-dominated. Additionally, the participants' most modern sex-role attitudes were toward gender stereotypes, though the most conservative attitudes were toward women and men's household lives. The variables that distinguished between husband-dominated and equality couples were age, education level, spouse's average income and resource evaluation; related, age, education level, spouse's average income, contribution toward household management and the occupational life of the woman were the variables that distinguished between husband-dominated and wife-dominated couples. This study also revealed the variables that affect couples' decision- making, demonstrating the necessity of considering several variables in the approach to the decision-making process of individual couples.
