Assuring integrity of permission assignment (PA) constraints is a difficult task in role-based access control (RBAC) because of the large number of constraints, users, roles and permissions in a large enterprise environment. We provide solutions for this problem using the conflict concept. This paper introduces the conflict model in order to understand the conflicts easily and to detect conflicts effectively. The conflict model is classified as a permission-permission model and a role-permission model. This paper defines two type conflicts using the conflict model. The first type is an inter-PA-constraints (IPAC) conflict that takes place between PA constraints. The other type is a PA-PAC conflict that takes place between a PA and a PA constraint (PAC) Also, the conditions of conflict occurrence are formally specified and proved. We can assure integrity on permission assignment by checking conflicts before PA and PA constraints are applied.

This study aims to analyze how the media represents marriage immigrant women in the reality of Korean multicultural society. In particular, by analyzing an EBS documentary titled, 'Multicultural Fierce Conflicts between Mother-in-law and Daughter-in-law', this study clarifies that this content adopted travel narrative to show conflicts between mother-in-law and daughter-in-law and solution of these conflicts. The documentary apparently shows mutual understanding and cultural diversity but still keeps representing these conflicts as individual's 'trivial' problems. Under this way of representation, social and structural problem or institutional problem in reality can be covered up by the medium of travel. It makes such a conflict look like an individual's 'trivial' problem can be solved by individuals.

The Conflicts between requirements may cause a failure of functions or even project. Currently, most of researches have focused on identifying requirements and some researchers have tried to resolve requirements conflicts but it was only based on requirement priority. This paper proposes the Creative Requirements Conflict Resolution (CRRC) to resolve requirement conflicts in a creative way using TRIZ methodology. TRIZ, which means the theory of solving inventor's problems, is made based on the analysis of over 2 million patent cases and helpful for developing a creative solution to resolve conflicts. CRRC classifies requirement conflicts into groups and then apply TRIZ theory related to each group. At the result of control experiment, CRRC provides the various kinds of creative solution for requirement conflicts.

The purpose of this study includes (1) to analyze the mediation process in which conflict mediation involves alternative stories through the mediation process after the characteristics of personal conflicts are analyzed (2) and to classify characteristics of the narrative of conflict mediation. This study attempts to examine mediation roles in the process mainly focusing on communication skills to which professional conflict mediators can apply. Based on this study, the usefulness of descriptive conflict mediation of social constructivism's perspective, one of the post-modern theories, was observed. The narrative mediation as a system that connects problems to conflicts with conversation and creates and develops the meanings of conflicts and problems in collaboration attempts to pursue new changes on the assumption of the subjectivity of human beings and the characteristic of the conflicts. Such a point supports the argument that conflicts should be approached from the communication perspective. Especially, it is expected that the fact that a variety of communication skills have great influence on conflict mediation becomes a key source to establishing communication study as one of mediation fields in conflicts.

The purpose of the present study was to figure out the effects of the result variables of hospital employees' conflicts on organizational effectiveness variables such as job satisfaction and organizational commitment. The present study was conducted with 305 subjects. The correlations among conflict, job satisfaction, and organizational commitment levels by conflict factor and by conflict type were analyzed using correlation analyses and multiple regression analyses were conducted to examine the effects of intra-organizational conflicts on conflict results while general and job related characteristics variable were controlled. According to the results of analyses, conflicts due to job satisfaction factors such as communication, leadership, and personality had significant negative effects on overall, intrinsic, and extrinsic job satisfaction levels and organizational commitment factors such as interdependence, leadership, and personality were significant conflict variables. By type, horizontal conflicts affected job satisfaction while vertical conflicts affected organizational commitment. When intra-organizational conflict levels were higher, job satisfaction and organizational commitment levels were lower and when job satisfaction levels were higher, organizational commitment levels were also higher

Purpose: The purpose of this study was to grasp the effects of role conflicts and burnout on turnover intention and provide intervention methods to decrease turnover intention in nurses of Oriental medicine hospitals. Method: The Subjects were 103 workimg Oriental Medicine Nurses. The data were analyzed by SPSS 18.0. Result: As a result, the mean scores of turnover intention, role conflicts, and burnout were 3.31, 3.53, and 3.44, respectively. Role conflicts had no significant difference in general characteristics, while burnout showed a difference in age, marriage, a working department, a night shift, and a salary, turnover intention showed a difference only in a night shift. Turnover intention was positively correlated with role conflicts(r=.310, p<.002) and burnout(r=.326, p<.001). Role conflicts and burnout explained 20.9% of turnover intention. Conclusion: Therefore, it is necessary to specify specialized and systematical nurses of roles to decrease turnover, make efforts to reduce burnout, and provide methods to decrease turnover intention in nurses of Oriental medicine hospitals.

Purpose: This study is a descriptive research conducted for looking into the role awareness level. role conflicts, and job satisfaction among professional home care nurses in the field of hospital based home care nursing service. Method: 154 specialized home care nurses in 63 hospitals and clinics that are implementing home care programs were subject to the study. Result: 1. The level of role awareness among professional home care nurses was $4.47\pm0.41$ on average out of 5. 2. The average score for role conflicts was $3.87\pm0.61$ out of 5. 3. In terms of job satisfaction level. $3.33\pm0.71$ was scored out of 5. 4. It has been discovered that there are statistically significant positive correlations among role awareness level, role conflicts(r= .224, P= .005), and job satisfaction level(r= .166, P=.040), while a negative correlation was detected between role conflicts and job satisfaction level(r=-.210, P= .009). Conclusion: The level of role awareness among professional home care nurses in the field of hospital based home care nursing service was very high and job satisfaction level was high when the level of home care nursing antecedents was high and the organization structure of working place was independent. But the level of role conflicts coming out of the weakness of job-supporting system was high. So the realistic alternative such as the improvement of working environment by administrative, institutional support, is required to make up for this problem in the future.

The surrogate safety assessment model which was developed based on the conflict theory by FHWA in the US is software to analyze traffic conflicts using the individual vehicle trajectory data from a microscopic traffic simulation model. This study aims at assessing the safety of different signal control strategies, including pre-time and actuated signal control, using the SSAM. To this end, this study effort has developed a microscopic traffic simulation model using VISSIM through a field study, and then produced the surrogate measures, including TTC, PET, DR, MaxS and DeltaS, and the numbers of conflicts, including rear-end, right angle and lane-changing conflicts. The assessment results indicated that the actuated signal control may produce more conflicts in terms of rear-end conflicts. The use of SSAM in the safety assessments for diverse traffic alternatives in a safe and fast way may contribute to the improvement of safety in the roadway transportation.

The purpose of this study was to investigate the effects of clinical nurses' job stress, work-family conflicts, and burnout on their depression. Data was analyzed using descriptive statistics, t-test, one way ANOVA, Pearson's Correlation Coefficient and Stepwise multiple regression analysis. The results of this study shows that the job stress of the nurses was higher than average, the work-family conflicts was moderate, burnout was less than moderate, and depression was mild. The higher the job stress, the higher the conflict between workplace and family, the higher the burnout, and the higher the depression was. The main factor impacting upon the mental health of nurses was work-family conflicts followed by burnout. Therefore, it is necessary to develop a program that can prevent job stress and resolve burnout and support work-family conflicts to prevent depression of clinical nurses and to improve quality of life.
