In this paper, we suggest lattice based role graph security management model which changes security level in mandatory access control model as well as constraint and role hierarchy systematically in role base access control model. In this model, we solved privilege abuse of senior role that is role graph model's problem, and when produce conflict between privileges, we can keep integrity of information by reseting grade of subject through constraint. Also, we offer strong security function by doing to be controlled by subject's security level as well as privilege inheritance by role hierarchy, Finally, we present the role graph algorithms with logic to disallow roles that contain conflicting privileges.

The purpose of this study was to identify the characteristics of coping behaviors of non-professional working mothers and find out the individual and situational factors which affect the degree of coping behaviors. For this research, the working mothers in non-professional job with children under age 18 answered the structured questionaire. The findings were as follows. First, the degree of coping behaviors was rather high in multiple role management strategies, strengthening family system and positive thinking, but rather low in housework socialization and role reduction/standard adjustment. Second, the effect of associated variables were different according to the subcategories of coping behaviors. So we conclude that, the coping behaviors of the non-professional working mothers were different from those of professional working mothers in some aspects, althought they have much similarities. The different aspects were 1) The relationship of family income and the degree of housework socialization was more evident. 2) The work-related variables did not affect the coping process significantly because of the conservative sex-role attitued of them. Second, non-professional working mothers should use coping behaviors such as housework socialization, role reduction/standard adjustment more for the more effective management of the role strain. Third, the attitude of occupational and parental role was one of the most important factors in using the role strain coping behaviors. And such an unconscious use of the coping behavior won't be helpful in the feeling of control over environment including role strain and active coping of working mothers.

This study focuses on the mediating role of creativity on the knowledge management process. To confirm focal hypotheses, we conducted survey on 538 employees of foreign subsidiaries of global enterprises. Main findings are: first, creativity turned out to positively mediate the effect of knowledge transfer on the firm's performance; second, the mediating role of creativity differs depending on the domain of acquiring knowledge such as exploitation and exploration. This research found that the influence of exploitative knowledge on knowledge creation and innovative performance was stronger. As such, among tension view and foundational view, which are two competing views on the relationship between knowledge and creativity, the latter is more soundly supported.

Constructed upon Knowledge Management (KM) processes, the current study aims to investigate the interrelationship between Knowledge Sharing (KS) attitude among the faculty members and KM processes in higher education institutes (HEIs) in Pakistan along with the intervening role of subjective norms between KM processes and KS attitude. This research incorporated the theory of Planned Behavior (TPB) and the theory of Reasoned Action (TRA) to conceptualize the KS behavior by using a sample frame of 302 academic and administrative staff from research-based HEIs in Quetta, Pakistan. A questionnaire-based survey was conducted on permanent faculty members from different universities of Quetta, Pakistan. The finding of the study shows a positive attitude among the researchers. The study empirically examined the interface between KM processes and KS attitude and higher education performance while providing valuable insights into the prevailing literature by investigating the mediating role of subject norms. The impact of subjective norms on KS attitude and KM process indicates the importance and basic determinant in organizational premises and improvement of skills of faculty management in HEIs. The partial mediation also reveals the importance of subjective norms in the development of faculty members' KM and KS attitude process.
