Based on the interval-valued intuitionistic fuzzy hybrid geometric (IIFHG) operator and the interval-valued intuitionistic fuzzy weighted geometric (IIFWG) operator, we investigate the group decision making problems in which all the information provided by the decision-makers is presented as interval-valued in tuitionistic fuzzy decision matrices where each of the elements is characterized by interval-valued intuitionistic fuzzy numbers, and the information about attribute weights is partially known. Anumerical example is used to illustrate the applicability of the proposed approach.

Objectives Decision-making in patients with schizophrenia has been known to be inefficient in both cognitive and affective aspects. The purpose of this study was to investigate the influence of anhedonia and self-esteem on the decision-making process in schizophrenia. Methods Twenty patients with schizophrenia and 21 healthy controls performed the 'apparel purchase decision-making task', during which they were asked to respond to the preference, fitness, and price suitability, before making the final purchase decision. Generalized estimating equation and correlation analysis were conducted to explore for the difference of decision making patterns and influential factors between the two groups. Results The patients showed lower odds ratio (OR) of the fitness on the apparel purchase decision than the controls [OR 0.190 ; 95% confidence interval (CI) 0.047-0.762, p = 0.019). In the patient group, there was no correlation between the number of purchased trials and the severity of anhedonia, but the number of purchased trials was negatively correlated with the Rosenberg Self-Esteem Scale score at a trend level (R = -0.436, p = 0.055). Conclusions Patients with schizophrenia considered the fitness of clothes less than healthy controls on apparel purchasing decisions. Schizophrenia patients with lower self-esteem were intended to buy more clothes.

The purpose of this study is to identify the differences of argumentation discourses for Socio-Scientific Issues in the types of decision-making and personality traits of pre-service biology teachers. For this study, SSI discussion topics were selected according to four types of decision making: logical reasoning, suggestion of complement, emotional base, and internal conflict. Three groups were constructed based on personality traits such as extroversion, acceptability, and integrity. Each three group used the workbook specially developed and freely used the smart device for discussion. A recorder and a camcorder were used to record each group, their behavior was recorded and the written materials during the discussion were collected for the results. Using Walton's analysis framework, the collected data analyzed in terms of the source of utterance, the process of dialogue shift, and the critical movements that can judge the reasoning of utterance. As a result of the study, it was confirmed that the decision-making type of SSI topics and learners' personalities were influential in the decision-making process of SSI small group discussions. This research shows that there is a need to develop instructional materials considering decision-making types and learners' personality types of students as well as pre-service teachers for SSI discussion.

While one main stream of research in GDSS (Group Decision Support System) is to investigate how GDSS affects decision-making performances of groups according to task types, support features, meeting facilitation modes and meeting environments. little study h3s been done about how group characteristics affect group decision processes and outcomes depending upon GDSS is provided or not. So far, most GDSS research has considered group characteristics (e.g. personality homogeneity) as given and did not include it as control variables in experiments. Therefore, the objective of this study is to investigate how members of two different groups perceive the use of GDSS in group meetings through lab experiments. The two groups are homogeneous and heterogeneous groups in terms of members' personality mix. This research found that the effect of GDSS is a function of groups' personality homogeneity in regards of the satisfaction on decision process and the communication thoroughness. The support of GDSS and the group homogeneity are proved to influence participant's perception about some dependent variables such as satisfaction on decision process.

Executive information systems (EIS) developers are faced with an increasingly difficult choice problem in the evaluation and selection of software packages. For many reasons, they frequently must depend on identification and evaluation of features of packages. When EIS software evaluation is regarded as an unstructured or semi-structured group decision making problem, the most appropriate decision-aiding methods are needed to help effective group interaction. This paper examines evaluation criteria of full-featured EIS packages and considers the priority of these criteria using the Analytic Hierarchy Process (AHP). Two exploratory phases are presented. In the first phase, an approach combining the AHP with the linear weighted attribute method is presented to computer qualities of some packages. In the second phase, the decision making group includes EIS developers, users, and vendors to prioritize evaluation criteria.

This study aimed to determine the effects of simulation-based practice education on nursing students' employability, career exploration behavior and decision-making self-efficacy. A non-equivalent control group pre-posttest of quasi-experimental design was used. A total of 120 nursing students located in J provinces, 60 students for the experimental group and 60 students for the control group. Study participants were a third-year student at college of nursing student. The experimental group participated in the study for 6 weeks. The results showed that the simulation-based practice education significantly improved employability(t=-2.31, p=.023) and career exploration behavior(t=-3.05, p=.003) of nursing students. However, there was no significant difference in the decision-making self-efficacy(t=-.87, p=.387). In conclusion, simulation-based practice education should be strengthened because it is useful for education of nursing students.

The purpose of this study was to examine the factors influencing copyright protection decision-making among Korean eSports game users. Data collection was conducted over a month at an eSports arena located in Seoul. Of the surveys collected, 354 valid data (88.5% of response rate) were analyzed in SPSS Ver. 20.0 through descriptive statistics, correlation and multiple regression analysis. The results showed that copyright protection decision-making regarding eSports contents was significantly influenced by legal/moral norm, perceive group norm, and past habit/behavior. Among the factors, legal/moral norm was found to be the most influential on copyright protection decision-making.

This study was conducted to examine the effects of an emergency treatment education program on nursing students' self-leadership, career decision-making self-efficacy, and nursing performance ability. The study was designed using a nonequivalent control group pretest-posttest design, and data were collected from June 1 to August 31, 2017. The participants consisted of 52 nursing students in D College of D City who were assigned to an experimental group (n=27) or control group (n=25). The pretest poll was performed on June 1, 2017 and posttest poll was performed 2 weeks later without any treatment in the control group. In the experimental group, the pretest poll was performed on July 25 before the emergency treatment education program and the posttest poll was performed on August 31 after the education program. The emergency treatment education program for the experimental group consisted of 2 hours of emergency treatment instruction, autonomously watching videos, and 4 hours of teaching elementary students about CPR for adults and first aid for airway obstruction, burns, bleeding, and fractures as a lecturer. The data were analyzed using descriptive analysis, independent t-test, $x^2$ test, and paired t-test with SPSS/WIN 20.0. After receiving the emergency treatment education program, a difference was observed in self-leadership (t=2.08, p<.05), career decision-making self-efficacy (t=4.22, p<.05) and nursing performance ability (t=5.02, p<.05) in the experimental group. The results of this study indicate that the emergency treatment education program was effective at increasing self-leadership, career decision-making self-efficacy, and nursing performance ability in nursing students.

The aim of this study is to analyse the effects of a career group counselling program on career attitude maturity and career decision self-efficacy in adolescents under probation. As a result, it was discovered that the career group counselling program had statistically significant differences in reality and preparedness among the sub-areas of career attitude maturity while there were no significant differences in determinacy. Also, the career group counselling program had statistically significant differences in goal selection, job information and future plans among the sub-area of career decision self-efficacy while there were no significant differences in problem solution. These results suggest that the career group counselling program had significant effects on career attitude maturity and career decision self-efficacy. For better career attitude maturity and career decision self-efficacy in adolescents under probation, more organized studies on career group counselling programs are needed and their usability should be reinforced.
