The purpose of this study was to investigate grit, career decision-making self-efficacy, career preparation behavior and job-seeking stress, and to identify the influencing factors on job-seeking stress of nursing students. Data were collected using questionnaires from 208 students who were 4th years in the nursing university in Gwangju, November 2020. The collected data was analyzed by descriptive statistics, pearson's correlation coefficient and stepwise multiple regression using IBM SPSS 21.0 program. The mean scores were as follows: grit, 3.21±0.50; career decision-making self-efficacy; 3.65±0.51, career preparation behavior; 2.57±0.48, job-seeking stress; 2.07±0.64. Job-seeking stress was found to have significant negative correlations with grit(r=-.308, p=.000) and career decision-making self-efficacy(r=-.336, p=.000). Job-seeking stress was found to have significant positive with career preparation behavior(r=.214, p=.002). The most influential factors influencing the job-seeking stress of nursing students were career decision-making self-efficacy(β=-.340, p=.000), career preparation behavior(β=.302, p=.000), grit(β=-.175, p=.010). and these factors explained 22.1% in job-seeking stress(F=20.605, p=.000). In conclusion, in order to control the job-seeking stress of nursing students, it is necessary to apply a program that improve the career decision-making self-efficacy and grit, and to practice career preparation behavior according to the individual level step by step.

Purpose: The purpose of this study was to develop a tailored simulation learning (SL) program and to evaluate the effects of the program on the clinical competency, clinical decision-making competency, and communicative competency of new nursing staffs in intensive care units (ICU) and emergency rooms (ER). Methods: In this quasi-experimental study, fifteen nurses were assigned to the experimental group and fifteen to the control group. The experimental group was given the SL program of four sessions, whereas the lectures of four sessions were given to the control group. Data were analyzed using a $x^2$-test, Mann-Whitney U test, and Kruskal-Wallis test with an SPSS program. Analysis of covariance was used to treat the covariate of pre communicative competency between the experimental and control groups. Results: Based on the education needs of new nursing staffs in ICUs and ERs, three learning scenarios and one evaluating scenario were developed for the SL program. The score for clinical competency, clinical decision-making competency, and communicative competency were significantly higher in the experimental group compared with the control group. Conclusion: The SL program is an effective learning strategy for new nursing staffs in ICUs and ERs. These findings suggest that an SL program be offered as an alternative for new nurse orientation and continuing nurse education.

In this paper, we propose a method of cooperative control (T-cell modeling) and selection of group behavior strategy (B-cell modeling) based on immune system in distributed autonomous robotic system (DARS). An immune system is the living bodys self-protection and self-maintenance system. these features can be applied to decision making of the optimal swarm behavior in a dynamically changing environment. For applying immune system to DARS, a robot is regarded as a B-cell, each environmental condition as an antigen, a behavior strategy as an antibody, and control parameter as a T-cell, respectively. When the environmental condition (antigen) changes, a robot selects an appropriate behavior strategy (antibody). And its behavior strategy is stimulated and suppressed by other robots using communication (immune network). Finally, much stimulated strategy is adopted as a swarm behavior strategy. This control scheme is based on clonal selection and immune network hypothesis, and it is used for decision making of the optimal swarm strategy. Adaptation ability of the robot is enhanced by adding T-cell model as a control parameter in dynamic environments.

In this paper, we propose a method of cooperative control based on immune system in distributed autonomous robotic system(DARS). Immune system is living body's self-protection and self-maintenance system. Thus these features can be applied to decision making of optimal swarm behavior in dynamically changing environment.For the purpose of applying immune system to DARS, a robot is regarded as a B lymphocyte(B cell), each environmental condition as an antigen, and a behavior strategy as an antibody respectively. The executing process of proposed method is as follows. When the environmental codintion changes, a robot select an appropriate beharior stategy. And its behavior stategy is stimulated and suppressed by other robot using communiation. Finally much stimulated strategy is adopted as a swarm behavior strategy. This control scheme is based on clonal selection and idotopic network hypothesis. And it is used for decision making of optimal swarm stragegy.

The primary focus of this study was on the issues associated with family and economic decision-making, in particular for the elderlyhood which might have to (or could be) share the family resources. This study regarded willingness to consider applying for Reverse Mortgage as an economic decision-making. The data was collected by interviewing 320 persons (over age 55) living in metropolitan areas in 2008. We selected 227 cases to find the influence of family, having both spouse and adult-children. We have used a theory of Planned Behavior by Fishbein to analysis three research questions. The results are as follows : first, the results partially explain willingness to consider applying for reverse mortgage using Fishbein's theory. Second, several results indicated that economic decision-makings within the family are influenced by several factors relating to other family member's view. They means that some of Subjective Norm variables, of Attitude Behavior ones, and of Perceived Behavior Control ones. Third, the result shows men and women respond differently to consider to applying for that policy. Men are conscious of the other people, i.e., friends, relatives except close family members, and, on the other hand, women are mindful of close family members, i.e., adult children. Forth, the group who have lower income showed higher intentions to consider that policy, when they have adult-children. Fifth, according to age group, pre-elderly group are influenced by consent of adult-children, a level of education, and on the other hand, elderly group are influenced by the other people, i.e., friends, relatives, a level of education, and so on. These results meaned that these distinct characteristics should be considered to establish Income Security policy for the pre-elderly and the elderly.

The purpose of this study is to identify the relationships of job stressor. coping strategies. and stress responses of manufactoring workers. Data were collected through self-reported questionnaires from 262 of the manufacturing workers in a local electronic company from July to August. 1999. For data analysis. Cronbach's a. Factor Analysis. Descriptive statistics. ANOVA. and Pearson's correlation coefficient with SPSS/PC+ 7.5 version program were used. The results were as follows: 1. Regard to the stress responses and coping strategies by sociodemographic variables. 'the overall stress responses' showed significant differences by sex. age. marrital state. The use of 'control coping strategy' showed significant differences by sex and the type of work. The use of 'avoid coping strategy' showed significant differences by sex. age. married state. year of career. and income. 2. The average scores of 'the job characteristics and participation in decision making factor'. 'the physical environmental factor'. and 'the role and leadership factor' were 2.66. 2.59. 2.59 in order. The average scores for 'the avoid coping strategy' and 'the control coping strategy' were 3.03. 2.97. The average scores for 'the overall. psychosoical. and physical stress responses' were 2.18. 2.18. 2.23. 3. The 'control coping strategy' was negatively related to 'the job characteristics and participation in decision making factor'. 'the role and leadership factor'. 'the psychosocial stress responses'. and 'the overall responses'. 'The control coping strategy' was positively related to all of 'the job stressors'. 'the physical stress responses', and' the overall stress responses'. 'The physical environment factor' was positively related to all of 'the stress reponses'. 'the role and leadership factor'. and 'the job characteristics and participation in decision making factor'. According to the results of this study, the suggestions were as follows: 1. The coping strategies of manufacturing workers in the specific job stress situation should be considered to future studies. 2. In order to applying the stress management program in the workplace. The organizational intervention focused on 'the job characteristics and participation in decision making' will be needed. 3. To support and use of 'control coping strategy' of the workers. the organizational efforts should be required.

This research empirical explores impacts of performance information use of decision makers in distributing financial resources. Based on theoretical review and previous researches, we organized three scenarios of general public administration, economic policy, and environmental policy and investigated the difference in budget distribution between measured information and simple information of success or failure by randomly divided experimental and control groups who are not experienced bureaucratic processed. The results indicate that experimental group judge by using performance information with numeric indicators and has more diversified patterns than control group. We suggest that repeated experiments including bureaucratic members to reduce bias of expertness and generalize the decision making models using performance information in future researches.

Aviation safety issues have drawn much attention from the international community due to the growing demand for air travel. Although it is a widely accepted fact that human-related factors are closely linked to aviation safety, there is lack of understanding what roles those factors play in aviation, in the field of air traffic control in particular. It has been reported that the role of air traffic controllers significantly affects air safety. This review will discuss cognitive aspects of expertise in air traffic control including time perception, working memory, reasoning, perception, attention, scanning/vigilance, decision making, and planning with examples of how each aspect can be dealt with in performing air traffic control duties. The relevant studies in psychology have also been briefly reviewed in the interest of enhancing understanding of characteristics of air traffic control tasks and the related human factors. This review concludes with a call for more in-depth research into cognitive factors in air traffic control.

Access control in dynamic environments needs the ability to provide more access opportunities of information to users, while also ensuring protection information from malicious users. Trust and risk are essential factors and can be combined together in access control decision-making to meet the above requirement. In this paper, we propose the combination of the trust and risk in access control to balance information accessibility and protection. Access control decision is made on the basis of trustworthiness of users and risk value of permissions. We use potential relations between users and relations between permissions in access control. Our approach not only provides more access opportunities for trustworthy users in accessing permissions, but also enforces traditional access control constraints such as Chinese Wall policy and Separation of Duty (SoD) of Role-Based Access Control (RBAC) model in an effective way.
