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.

This paper design a role-based access control model that can resolves the complicated problems of access control requirements. In this paper, we designed an access control model which can control a permission making use up role-based access control, can guard the confidentiality, integrity and availability of information and can control illegal information flow. The designed access control model can protect resources from unauthorized accesses based on the role, multi-level security policies of security level, integrity level and ownership.

With role-based access control, access decisions are based on the roles that individual users have as part of an organization. In this paper, we propose a new RBAC model that a user delegate a permission to another user with function-unit for practical organization. A function-unit delegation is more safe than existing delegations on RBAC model. And FuRBAC model has a authentication to supervise security problems.

The purpose of this study was to investigate how gender role attitudes affect clothing involvement and clothing consumption behaviors in young female generation by changing the traditional sex role stereotype. For the research, the survey was conducted for a month from June 15 to July 15, 2009. Data was collected a total of 368 questionnaires from 20's female university students and analyzed 301 questionnaires with SPSS 12.0. The results were as follows. First, the results of factor analysis on gender role attitudes confirmed the multifactorial theory of gender schema: modern masculinity, conservative gender roles, modern feminity based on emotion, gender role openness, and traditional feminity. Second, gender role attitude of female university students was a little conservative but flexible to accommodate masculinity and active in the emotion expression. Third, gender role attitudes had important effects on clothing involvement which was identified into 4 different factors; fashion involvement, clothing interest, performance risk, and social psychological risk. Fourth, gender role attitudes were related with clothing consumption behaviors as like shopping orientation, on-going information search behavior and brand loyalty because of needs for innovation, exhibition and differentiation. Therefore, it was concluded that not only 'androgynous' from modern feminity based on emotion but also 'masculinity' was applied to important fashion marketing strategic tools by statically affecting female consumer's clothing involvement and clothing behaviors.

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.

In this paper, this model ensures confidentiality and integrity of mandatory access cotrol policy which based on fuzzy function with importance of information. And it solves authorization abuse problem through role graph creation algorithm and flowing policy that security grade is applied. Because this model composes role hierarchy which bind similar role concept to apply to commercial environment, it has expansile advantage by large scale security system as well as is easy that add new role.

Purpose: This study aimed to investigate the role of hospital-based home health nursing in community care by examining the institutional progress of hospital-based home health nursing and the current status of home health nursing in Korea. Methods: Korean research data, national statistical data, government press releases, and related laws were investigated to clarify the role of hospital-based home health nursing in community care. Results: Korean visiting medical care services, including hospital-based home health nursing, was not found to be sufficient nationwide. The supply of home health nursing did not increase due to the nature of the visiting services that required transportation time, poor profitability due to insufficient insurance fees, and increase in acute beds. Conclusion: The nature of the Korean medical environment and visiting medical care makes it challenging to establish a visiting medical supply system for community care. Therefore, hospital-based home health nursing is an important infrastructure for visiting medical care, and will be a valuable resource to link discharged patients returning to the community when moving health care services. Hence, laws and institutional supplementation to expand the role of home health nursing agencies nationwide are needed along with addressing the limitations in the supply of home health nurses.

Role-based Access Control(RBAC) model has advantage of easy management of access control with constraints such as permission inheritance and separation of duty in role hierarchy. However, previous RBAC studies could not properly reflect the real-world organization structure with its role hierarchy. User who is a member of senior role can perform all permissions because senior role inherits all permissions of junior roles in the role hierarchy. Therefore there is a possibility for senior role members to abuse permissions due to violation of the least privilege principle. In this paper, we present a new model of role hierarchy, which restricts the unconditional permission inheritance. In the proposed model, a role is divided into sub roles(unconditional inheritance. restricted inheritance, private role), keeping organization structure in corporate environment. With restricted inheritance, the proposed model prevents permission abuse by specifying the degree of inheritance in role hierarchy.

This study was based on a recognition that the married mens role of performing multiple roles should be redefined. Family and work roles were composed of four domains, such as marital, parental, homecare, and occupational roles. The data of this study had been collected from the married men, who had his spouse and his first child younger than twelve years old, and held a job in Seoul. The main findings of this study were as follows: First, as for family and work role salience perceptions, it showed that men relatively higher perceived four role saliences: marital role salience, parental role salience, homecare role salience, and occupational role salience. Second, among four salience perceptions of family and work roles, married men highest perceived homecare role salience while they lowest perceived occupational role salience. Third, regarding the married mens family and work role performances, the parental and homecare roles were equally performed and higher than the marital and occupational roles. In general, the degree of family and work role salience perceptions of the married men in Korean society was higher than that of family and work role performances.
