Multi-criteria decision making is deducing the relative importance in the criterion of decision making and each alternative which is able to making a variety of choices measures the preferred degree in the series of low-raking criterions. Moreover, this is possible by synthesizing them systematically. In general, a fundamental problem decision maker solve for multi-criteria decision making is evaluating a set of activities which are considered as the target logically, and this kind of work is evaluated and synthesized by various criterions of the value which a chain of activities usually hold in common. In this paper, we are the eigenvector methods in weights calculating. For the purpose of making optimal decision, the data of five different car models are used. For computing, we used Visual Numerica Version 1.0 software package.

This study is designed to review the methods of duplicate copies decision making in the academic library. In this thesis, I surveyed queueing & markov model, statistical model, and simulation model. The contents of the study can be summarized as follows: 1) Queueing and markov model is used for one of duplicate copies decision-making methods. This model was suggested by Leimkuler, Morse, and Chen, etc. Leimkuler proposed growth model, storage model, and availability model through using system analysis method. Queueing theory is a n.0, pplied to Leimkuler's availability model. Morse ad Chen a n.0, pplied queueing and markov model to their theory. They used queueing theory for measuring satisfaction level and Markov model for predicting user demand. 2) Another model of duplicate copies decision-making methods is statistical model. This model is suggested by Grant and Sohn, Jung Pyo. Grant suggested a model with a formula to satisfy the user demand more than 95%, Sohn, Jung Pyo suggested a model with two formulars: one for duplicate copies decision-making by using standard deviation and the other for duplicate copies predicting by using coefficient of variation. 3) Simulation model is used for one of duplicate copies decision-making methods. This model is suggested by Buckland and Arms. Buckland considered both loan period and duplicate copies simultaneously in his simulation model. Arms suggested computer-simulation model as one of duplicate copies decision-making methods. These methods can help improve the efficiency of collection development and solve some problems (space, staff, budget, etc, ) of Korean academic libraries today.

There have been growing recognition on the needs of coordination of diverse activities across cross-functional business areas necessarily involving group decision-making processes. Although many group decision-making support tools and methods have been introduced to enable the collaborative processes of group decision-making, they often lack features supporting the dynamic complexity issues. This study proposes system dynamics modeling approach based on simulation techniques to deal with the group decision-making tasks having properties of dynamic complexity.

The changing structure of organization and the increasing diversity of business have forced organizations to have abilities to coordinate dispersed business activities. They have required cooperation and coordination among the functional units in the organization which should involve group decision-making processes. Although many group decision-making support tools and methods have been introduced to enable the collaborative process of group decision-making, they often lack the features supporting the dynamic complexity issue frequently occurring at group decision-making processes. This results in cognitive unfit between the group decision-making tasks and their supporting tools, bringing about mixed results in their effects on group decision-making. This study proposes system dynamics modeling as a group decision-making support tool to deal with the group decision -making tasks having properties of dynamic complexity in terms of cognitive fit theory.

Regarding all methods of decision making as parts of the same subject, one is astounded to find that the field speaks to the practitioners about multicriteria decision making with a multi-forked tongue, different methods give different and conflicting outcomes even for very simple decisions. In this paper, five well-known decision theories are described and used to work out a simple decision to choose the best of three cars. The outcomes turn out not to be the same for all the methods, which is troubling because one would expect unique answers in decision making. Several "meta" criteria that are essential for making a decision theory to make a choice as to which decision approach is best.h is best.

Purpose: This study was done to identify participation by home healthcare nurses in clinical decision making and factors influencing clinical decision making. Methods: A descriptive survey was used to collect data from 68 home healthcare nurses in 22 hospital-based home healthcare services in Korea. To investigate participation, the researcher developed 3 scenarios through interviews with 5 home healthcare nurses. A self-report questionnaire composed of tools for characteristics, factors of clinical decision making, and participation was used. Results: Participation was relatively high, but significantly lower in the design phase (F=3.51, p=.032). Competency in clinical decision making (r=.45, p<.001), perception of the decision maker role (r=.47, p<.001), and perception of the utility of clinical practice guidelines (r=.25, p=.043) were significantly correlated with participation. Competency in clinical decision making (Odds ratio [OR]=41.79, p=.007) and perception of the decision maker role (OR=15.09, p=.007) were significant factors predicting participation in clinical decision making by home healthcare nurses. Conclusion: In order to encourage participation in clinical decision making, education programs should be provided to home healthcare nurses. Official clinical practice guidelines should be used to support home healthcare nurses’ participation in clinical decision making in cases where they can identify and solve the patient health problems.

Purpose: The study was conducted to investigate the effect of career barrier, satisfaction, and career decision making pattern on career search behaviors in male nursing students. Methods: Data were collected through structured questionnaires that included general characteristics, career barrier, satisfaction, career decision making pattern and career search behaviors and were analyzed by descriptive statistics, ANOVA, t-test, Pearson correlation coefficient and multiple regression using SPSS/PC+ program. Results: The results of the research suggest the two aspects of career search behaviors as being self-exploration and environmental exploration. The rational pattern, among the types of satisfaction and career decision making pattern, was found to have a meaningful effect on self-expression. On the other hand, dependent pattern, among the satisfaction and career decision making pattern, was found to have an effect on career search patterns. Conclusion: It is considered that, based on the results of this study, diversified approaches that consider individual career decision making patterns such as rational pattern and dependent pattern as well as the methods to enhance the satisfaction of male nursing college students for career guidance are needed.

Purpose : The purpose of this study was to identify the mediating effect of role clarity in the relationship between clinical decision-making abilities and job stress among advanced practice nurses at tertiary hospitals. Methods : The participants were 137 advanced practice nurses. The assessment tools were clinical decision-making in nursing scale, role ambiguity scale, and Korean occupational stress scale (KOSS-26). Data were analyzed with the SPSS/24.0 program and mediation analysis was performed according to the Baron and Kenny methods. Results : There were significant relationships between clinical decision-making abilities and job stress (r=-.33, p<.001), and role clarity and job stress (r=-.29, p=.001). Role clarity showed partial mediating effects in the relationship between clinical decision-making abilities and job stress (Z=2.02, p=.043). Conclusion : Therefore, to reduce advanced practice nurses' job stress, it is necessary to develop a program and strategies to increase their clinical decision-making abilities.

Purpose: The aim of this study was to testify correlations between critical thinking disposition and decision making styles. Methods: The subjects of this study were 193 freshman nursing students in the 1 nursing school located in Incheon area. The data were collected by self-reporting questionnaires. The data were analyzed using descriptive statistics and Pearson correlation coefficient analysis. Results: The score of critical thinking disposition was revealed 3.96 points. The highest was inquisitiveness, the lowest was systematicity. The most frequent decision making style was revealed a rational decision making. The next was dependant decision making, intuitional decision making as follows. The critical thinking disposition and rational decision making had a statistically significant positive correlation. However the critical thinking disposition and dependant decision making had a statistically significant negative correlation. Conclusion: With these findings, we are found that the more increasing critical thinking disposition, the more developing rational decision making. It will suggested that the program for increasing nursing student's critical thinking disposition focused on systematicity, analyticity and truth seeking in critical thinking sub categories.
