This study aims to explore the role of Khan's engagement dimension previous study in mediating the relationship between work-life balance and in-role and extra-role performance of salesforce. To measure the data, a quantitative approach conducted through a survey of the sales force in the financial services industry sector in Makassar City, Indonesia. We determine the sample by using purposive sampling technique, and a total of 188 salesforce respondents. SEM-PLS with the second-order model was applied to test the measurement model and the mediator role of the engagement. The results show that the engagement dimension fully mediates the effect of work-life balance on both in-role and extra-role performance direct or indirect effect. the findings in this study also address the great concern of both individuals and organizations that the antecedents of the work-life balance variable are fundamental reasons for improving performance. The results of this study indicate that the work-life balance program positively influences engagement. Overall, we can conclude that commitment not only serves as a means for employees to fulfill formal job requirements. This can also encourage them to take action that goes beyond the precise requirements of their work by presenting them physically, emotionally, and cognitively in the work environment.

Purpose - The purpose of this study is to test the impact of job crafting on in/extra-role performance in Chinese context. In addition, it intends to verify the mediating effect of work engagement on the relationship between job crafting and in/extra-role performance. Research design, data, and methodology - Survey data were collected from employees of the companies in Hebei, China, for about two months, from early January 2022 to early March 2022. A total of 300 copies were distributed, and 240 copies were collected (80%), of which 222 copies were used for the final analysis. Data were analyzed for statistical tests of the measurement model and hypotheses using IBM SPSS Statistics 25 and Amos 25. Result - The analysis results are as follows. First, job crafting has a direct effect on work engagement. Second, work engagement increased employees' in/extra-role performance. Third, the mediating effect of work engagement was verified in the relationship between job crafting and employees' in/extra-role performance. Conclusion - This study expands the job demand-resource model by revealing the effect of job crafting, which changes the job given to oneself, on in/extra-role performance. In addition, this study investigated the impact of work engagement on the relationship between job crafting and in/extra-role performance.

RBAC(Role-Based Access Control) has advantages in managing access controls, because it offers the role inheritance and separation of duty in role hierarchy structures. Delegation is a mechanism of assigning access rights to a user. RBDM0 and RDM2000 models deal with user-to-user delegation. The unit of delegation in them is a role. However, RBAC does not process delegation of Role or Permission effectively that occurs frequently in the real world. This paper proposes a Time Constraints Permission-Based Delegation Model(TCPBDM) that guarantees permanency of delegated permissions and does not violate security principle of least privilege and separation of duty. TCPBDM, based on the well-known RBAC96, supports both user-to-user and role-to-role delegation with time constraints. A delegator can give permission to a specific person, that is delegatee, and the permission can be withdrawn whenever the delegator wants. Our model is analyzed and shown to be effective in the present paper.

The existing access control models have the demerits that do not provide the limit function of using resources by time constraint, the restricted inheritance function as a superior role in role hierarchy, the delicate delegation policy and the limit function of using resources by the location information about a user for the access control in ubiquitous environment. This paper proposes an Extended-GTRBAC model is suited to the access control in ubiquitous environment by applying to sub-role concept of GTRBAC model that the application of resources can be restricted by the period and time and PBDM and considering the location information about a user on temporal constraint. The proposal model can restrict the inheritance of permission in role hierarchy by using sub-role, provide the delicate delegation policy such as user-to-user delegation, role to role delegation, multi-level delegation. multi-step delegation, and apply diverse and delicate access control policy which is suited the characteristic of ubiquitous environment by considering the location information about a user on temporal constraint.

This paper is a study on the AC and PMI model for the defense computer network. It is suggested that the organization plan of PMI model is a proper model for the characteristics of military system and military defense network security demands based on defense PKI system. Futhermore, it will be presented both various types of defense AC and AC according to the role and clearance in PMI. Defense AC will provide strong users' authentication and Role Based Access Control to give more secured and trusted authentication service by using users' attribute such as role and clearance.

This paper implements an improved model for access control enforcement in enterprise environments. The integration of the task role-based access control model and the "conflicting entities" administration paradigm supply a specification of static and dynamic separation of duty requirements in the workflow environment. The implemented Extended Task Role-Based Access Control model can deal with the conflicting entities for workflow oriented tasks. It will support elaborate separation of duty policy to tasks in enterprise environment through the classification of enterprise sessions according to their characteristics.

An appropriate parent role model for alcohol, tobacco and other drug abuse prevention in adolescence was designed as part of a comprehensive effort to reduce the use of alcohol, tobacco and other drugs by underage youth. The content of the model offers a new and positive chemical health model. The model calls for development of a set of guidelines that can provide the framework for examining alcohol, tobacco and other drug use. The actions of adults in the community, especially parents, are very important factors in whether or not youth use chemicals. So these guidelines can be used to assist parents and other adults with questions such as, what can we say to young people about using alcohol, tobacco or other drugs except that it's against the law? At what age and times are discussions appropriate? What can we do to make our community a healthier place in which young people can make better decisions about alcohol, tobacco and other drug use? The model acknowledges and affirms the legal and appropriate use of alcohol and other drugs as well as supports the decision not to drink. It encourages participants to consider their own guidelines for using and not using alcohol and other drugs. The guidelines can also be used as the basis for early intervention when use is illegal, unhealthy or risky. It is important to note that the model affirms healthy and appropriate use as well as nonuse.

RBAC(Role Based Access Control) is an access control method based on the user's roles and it provides more flexibility and applicability on the various computer and network security fields than DAC(Discretionary Access Control) or MAC(Mandatory Access Control). In this paper, we newly propose ERBAC$_{0}$(Extended RBAC$_{0}$) model by considering subject's and object's roles additionally to REAC$_{0}$ model which is firstly proposed by Ravi S. Sandhu as a base model. The proposed ERBAC$_{0}$ model provides finer grained access control on the base of subject and object level than RBAC$_{0}$ model.
