Delegation is a powerful mechanism that allocates access rights to users to provide flexible and dynamic access control decisions. It is also particularly useful in a distributed environment. Among the representative delegation models, the RBDM0 and RDM2000 models are role delegation as the user to user delegation. However, In RBAC, the concept of inheritance of the role class is not well harmonized with the management rules of the actual corporate organization. In this paper, we propose an Adding Attributes on Permission-Based Delegation Model (ABDM) that guarantees the permanence of delegated permissions. It does not violate the separation of duty and security principle of least privilege. ABDM based on RBAC model, supports both the role to role and user to user delegation with an attribute. whenever the delegator wants the permission can be withdrawn, and A delegator can give permission to a delegatee.

This study was conducted to analyze the effect on entrepreneurial intention and empirically analyze which factors have the greatest influence. To this end, self-achievement motivation, indirect experience, role model, awareness of entrepreneurs, and fear of business failure were set as independent variables as factors influencing entrepreneurial intention. In order to empirically analyze this, 399 valid samples for the general public were analyzed. SPSS 25.0 was used for statistical analysis. As a result of the empirical analysis of this study, self-achievement motivation, indirect experience, role model, awareness of entrepreneurs, and fear of business failure all had a positive and significant effect on entrepreneurial intention. The results of this study confirmed that self-achievement motivation had the greatest influence among the factors affecting entrepreneurial intention. It is significant in that indirect experiences and role models such as theoretical entrepreneurship lectures, special entrepreneurship lectures, and parents or acquaintances influence entrepreneurial intention.

Purpose: The aim of this study was to provide basic data to aid in the effective adoption of the preceptor system for new paramedics by assessing the preceptor role awareness among senior 119 paramedics in the field. Methods: A questionnaire was administered to 182 senior paramedics who each had more than 3 years field experience. The questionnaire measuring preceptor role awareness was composed of 64 items with responses based on a 5 point Likert scale. Data were collected from July 31, 2018 to August 29, 2018, and were analyzed with IBM SPSS version 24.0. Results: The average score for preceptor role awareness was 3.87 (supervisor = 3.95, resource person = 3.88, role model = 3.85, and instruction designer = 3.81). There were significant differences in preceptor role awareness among the participants based on competence (p =.002) and clinical skill (p =.000). Also, there were high positive correlations between preceptor role awareness and its subdivision (p <.01). Conclusion: For effective operation of the preceptor system in the future, the preceptors' role as designers of instruction and role models should be enhanced, Also, future preceptors are very important in the improvement of competence and clinical skill in the preceptor system. Therefore, it is necessary to provide training that enables new preceptors to effectively adopt and operate the preceptor system.

The present study examined the causal relationships among nurses' perceived autonomy, job satisfaction, work environment (work overload, role conflict, situational support, head nurses' leadership), personal aspects(experiences, need for achievement, professional knowledge and skill) by constructing and testing a theoretical framework. Based on literature review nurses' perceived autonomy and job satisfaction were conceived of as outcomes of the interplay among work environment and personal characteristics. Work environment factors involved work overload, role conflict, situational support, and head nurses' leadership (task oriented leadership, relation oriented leadership). Personal charateristics included experiences, need for achievement, and professional knowledge and skill. Three large general hospital in Chonbuk were selected to participate. The total sample of 516 registered nurses represents a response rate of 92 percent. Data for this study was collected from July to September in 1998 by Questionnaire. Path analyses with LISREL 7.16 program were used to test the fit of the proposed conceptual model to the data and to examine the causal relationship among variables. The result showed that both the proposed model and the modified model fit the data excellently. It needs to be notified, however, that path analisis can not count measurement errors; measurement error can attenuate estimates of coefficient and explanatory power. Nevertheless the model revealed relatively high explanatory power. 42 percent of nurses' perceived autonomy was explained by predicted variables; 32 percent of nurses' job satisfaction was explained by by predicted variables. Tn predicting nurses' perceived autonomy the findings of this study clearly demonstrated the work overload might be the most important variable of all the antecedent variables. Head nurses' relation oriented leadership, situational supports, need for achievement, and role conflict were also found to be important determinants for nurses' perceived autonomy. As for the job satisfaction, role conflict, situational supports, need for the achievement, and head nurses' relation oriented leadership were in turn important predictors. Unexpectedly the result showed perceived autonomy have few influence on job satisfaction. The results were discussed, including directions for the future research and practical implication drawn from the research were suggested.

In this paper, we propose FAS model for establishing trust based on digital certificates in Grid security framework. The existing RBAC(Role Based Access Control) model is extended to provide permissions depending on the users‘ roles. The FAS model is designed for a system independent integrated Grid security by detailing and extending the fundamental architecture of user, role, and permission. FAS decides each user’s role, allocates access right, and publishes attribute certificate. FAS is composed of three modules: RDM, PCM, and CCM. The RDM decides roles of the user during trust negotiation process and improves the existing low level Grid security in which every single user maps a single shared local name. Both PCM and CCM confirm the capability of the user based on various policies that can restrict priority of the different user groups and roles. We have analyzed the FAS strategy with the complexity of the policy graph-based strategy. In particular, we focused on the algorithm for constructing the policy graph. As a result, the total running time was significantly reduced.

The purpose of this study is to investigate, analyze the purchasing behavior of fashion goods according to life style and role model of preteen generation, and provide manager or marketing planner for the reference data so that they can understand preteen generation and make proper strategy efficiently. So called, preteen market focusing on 1014 generation (from ten to fourteen years old) is highlighted. This generation created between the year 1989 to 1993 after Seoul Olympic monopolize parent's love in abundant economic environment and rise to the core of consumption subject. Products aiming at this preteen generation continuously though consumption mind was shrunk greatly due to recession. Only 2~3 years before preteen market was regarded as grey zone which doesn't belong to not only children (between six and nine years old) but also teenagers (between fifteen to eighteen years old). But in recent day their purchasing powers have increased rapidly and age group is divided on details, so that preteen market has become a niche market. Subjects were 333 persons consisting of students in the 4th~6th grade of primary school and the 1st~2nd grade of middle school in Daegu city. Measuring instruments are as follows: 5questions to differentiate preteen generation, 22 questions to measure life style, 17questions (which have six sub-factors such as purchase motive, factor of product selection, utilization of informant, purchase time, purchase place, and purchase method) to measure the purchase behavior of fashion goods measurement, and 16 questions (which have four sub-factors such as parent, entertainer & sports stars, brothers and sisters, friends) to measure model of role. Statistical data were processed by SPSS 10.0 programs. Frequencies, Factor analysis, Cluster analysis, ANOVA, Cross analysis, Multiplex regression analysis, and Duncan's multiple range test were carried out.

This paper examines the evolving role of ijang(village representative) and his job stress during Pyeongchang floods in 2006. Results based on telephone survey and interviews reveal that ijang played a crucial role in evacuating residents, allocating resources and commanding the recovery, although official job description considered him as only a mediator between local officers and villagers. Moreover, unexpected enormous burden created severe job stress to many ijangs; while 60 percent felt like quitting the job, about three fourth felt fretful whenever the telephone rang and lost some weights. Chi-square analysis also indicated that previous job training, villagers' abuse, and disaster damages were significantly related with job stress. These results suggest that the emergent human resources model rather than the command and control model can be an effective approach for a disaster management plan in rural Korea.

In general RBAC(Role-Based-Access Control) model, senior role has junior role's permissions by virtue of role hierarchy. But although the opposite case is needed partially in medical institutions, such case cannot be performed in medical information systems. This is because inheritances of permissions in role hierarchies are static. In order to tackle this problem, this paper defined a dynamic role assignment, thereby proposed the way for the junior temporarily to be able to perform the permissions of the senior, and showed the applications of medical information systems.

The paper examines how empowering leadership and intrinsic motivation contributed to explaining in-role behavior. In order to verify the relationships and mediating effect, data were collected from 414 individuals in employees working in small and medium-sized firms at Jinju, Changwon, Gimhae, Busan City to test theoretical model and its hypotheses. All data collected from the survey were analyzed using with SPSS 18.0. This study reports findings as follows: first, the relationship between the empowering leadership and the intrinsic motivation is positively related. Second, there was also a positive correlation between the intrinsic motivation and the in-role behavior. Third, the relationship between the empowering leadership and the in-role behavior is positively related. Finally, the intrinsic motivation played as a partial mediator on the relationship between empowering leadership and in-role behavior. Based on these findings, the implications and the limitations of the study were presented including some directions for future studies.
