To adapt environment changing high speed and improve rapidly response ability for variation of environment and reduce delay time of decision making inlet agents, the derivation of user's preference and alternative are required. In this paper, we propose an efficient coordination method of multi-agents based on fuzzy decision making with the solution proposed by agents in the view of Pareto optimality. Our method generates the optimal alternative by using weighted value. We compute importance of attributes of winner agent, then can obtain the priorities lot attributes. The result of our method is analyzed that of Yager's method.

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.

We suggest the C2 modeling method to develop a simulation model for training command groups which consist of commanders and staffs. By using C2 models in constructive simulation models, combat entities or units directly receive and execute orders from a command group without mediating human role players. We also compare combat results from suggested modeling method with the results of existing models by building and implementing a simulation model with C2 models. Our analysis by comparison demonstrates advantages of suggested method to model C2 for computer assisted exercises.

The purposed of this study was to identify the factors that affect Confidence in Performance Patient Safety Management targeted nursing students. The study subjects were 228 nursing students. The nursing students experienced patientl safety accidents in the fall (50.0%), needle puncture (18.5%), Patient identification error (12.0%), injection medication error (7.5%) and oral medication errors (4.3%). In the logistic regression analysis, Attitude of Patient Safety Management(t=6.09, p<.001), Clinical Decision Making(t=3.97, p<.001) and gender(t=2.56, p=.011) were significant factors related to Confidence of Performance Patient Safety Management. Based on the results of this study, we propose to develop a convergence education program that considers patient safety management attitude, clinical decision making ability, and gender in order to improve confidence of performance patient safety management of nursing students.

This study was conducted to identify factors influencinging confidence in performing patient safety management (PSM) of nursing students. The subjects of this study were 230 nursing students in four universities in two cities. Data were collected between June 22 and June 26, 2020 using by completing structured self report questionnaires. Data were analyzed using SPSS/WIN 21.0. programs. In correlation analysis, significant positive correlations were found between confidence in performing PSM, PSM knowledge(r=.321, p<.001), PSM attitude(r=.584, p<.001), and clinical decision making ability(𝛽=.460, p<.001). In multiple regression analysis, PSM attitude(𝛽=.35, p=.005) and clinical decision making ability(𝛽=.23, p<.001) were factors predicting confidence in performing PSM, which explained 34.2% of the variance in the model. Therefore, we emphasize that continuing customized convergence educational programs are required to improve nursing student's confidence in performing PSM.

This study was performed to examine that convergence-based integrated simulation practice program curriculum effects the clinical decision making, problem solving competence, clinical competence and confidence of core fundamental nursing skill performance for nursing students. After the convergence-based integrated simulation practice program, there were significant increased in problem solving process(t=-3.052, p<.01), clinical competence(t=-4.279, p=.000), and confidence of core fundamental nursing skill performance(t=-2.416, p<.05). The finding of this study verified that the integrated simulation practice program curriculum can be used for improvements of problem solving competence, clinical competence and confidence of core fundamental nursing skill performance for nursing students. It is necessary to develop a scientific analytical evaluation tool and program, and it would be necessary to have a system for scientifically analyzing the integration of simulation practical courses by nursing college students by grade level and subjects.

This paper is to build a spatial decision support system designed to solve problems relevant to the decision-making for retail center locations. For construction of the system this paper discusses the primary procedures of spatial modeling and issues of data, which are required for integrating spatial interaction models to GIS having capability of managing, analyzing and visualizing spatial data sets. Lexington, Kentucky, is selected as a case study to implement the spatial decision support system based on the spatial modeling module. This system for retail center locations is useful of estimating the catchment areas more accurately and analyzing resultant flow patterns. And this system can make spatial analysis efficiently for what-if scenarios such as an intended retail center or changing demand. The benefits of adopting this system allow the decision makers to plan the investment strategies and search for stable market structure.

The purpose of this study is to confirm the moderating effect of the 'IRrelevance Processing'(IRP) on the relationship between decision maker's openness and business problem solving creativity (BPSC). In order to confirm the psychological mechanism of BPSC and openness, we developed the irrelevance processing. In particular, the creativity in this study is different from the general creativity studied in psychology. BPSC is a study with practical value applied in the management environment. The results showed that openness of the decision maker was correlated with the BPSC, and that the irrelevance processing was a psychological mechanism to moderating effects relationship between openness of decision makers and BPSC. This paper proved the correlation between the propensity of decision makers and BPSC, and contributed to the study of corporate creativity by identifying the psychological mechanisms.

신제품 또는 신기술이 도입되는 시장에서는 보통 선두 진출자가 먼저 시장을 개척하고 나중에 후발 기업이 시장에 진출한다. 시장 진출자는 생산능력이 과한 경우 과투자의 위험이 존재하는 반면, 부족한 경우 잠재고객의 수요에 적절히 대응하지 못하여 고객을 유치하지 못하게 된다. 또한 신규 시장에서 선두 진출자의 광고효과는 시장 규모를 키움으로써 자신의 입지뿐 아니라 후발 주자의 몫까지 키워주는 양날의 칼과 같은 역할을 한다. 그렇다면, 선두 진출자가 취할 수 있는 최적의 생산능력 확장 정책과 광고 정책은 어떻게 결정할 수 있을까? 본 연구에서는 신제품이 도입되는 시장에서 선두 진출자가 경쟁자의 시장 진입을 예상하는 경우, 기존 시장 진출자가 취할 수 있는 생산 능력 확장 정책과 광고 수준에 대한 의사 결정모형을 수립하기 위해 Bass의 확산 모형을 확장하여 적용하였다.

Purpose: The purpose of this study was to explore the relationships of critical thinking disposition (CT), nursing work environment (NWE), and clinical decision making ability among nurses. Methods: A cross-sectional, descriptive study design was conducted on 192 nurses who had worked for more than six months in five general hospitals. A self-reported questionnaire was used to collect data, which included demographics, CT, NWE, and clinical decision making ability. Results: The mean score of CT was 3.5. The highest score was on the objectivity of CT and the lowest on systematicity. The mean score of NWE was 2.3. The highest score was on the collegial nurse-physician relations of NWE and the lowest on the staffing and resource adequacy. The mean score of clinical decision making ability was 3.3. In hierarchical multiple regression, affecting factors on clinical decision making ability were CT and NWE. Conclusion: The findings showed that clinical decision making ability is associated with CT and NWE. To improve clinical decision making ability, it is important to improve CT. In addition, it should be considered to improve NWE where the nurses can make a decision with their job through critical thinking.
