Authentication and access control are essential requirements for the information security of distributed environment. Delegation is process whereby an initiator principal in a distributed environment authorizes another principal to carry out some functions on behalf of the former. Delegation of access rights also increases the availability of services offer safety in distributed environments. A delegation easily provides principal to grant privileges in the single domain with Role-Based Access Control(RBAC). But in the multi-domain, initiators who request delegation may require to limit the access right of their delegates with restrictions that are called delegate restriction to protect the abuse of privilege. In this paper, we propose the delegation view as function of delegation restrictions. Proposed delegation view model not only prevent over-exposure of documents from granting multiple step delegation to document sharing in multi-domain with RBAC infrastructure but also reduce overload of security administrator and communication.

This study examined the relationship between delegation preparedness and job satisfaction in comprehensive nursing care service wards. Data were collected from 126 nurses who had been working in the comprehensive nursing care wards of five general hospitals located in Seoul and Gyeonggi Province, from May 26 to June 7, 2017. Data were analyzed using independent t-test, one-way ANOVA, and Pearson's correlation coefficients. The delegation education showed a significant difference in delegation preparedness (t=-2.77, p=.006). A statistically significant positive correlation was observed between delegation preparedness and job satisfaction (r=.43, p<.001). Job satisfaction was significantly correlated with understanding the task (r=.26, p=.003), delegation of the task classification (r=.45, p<.001), understanding the delegation (r=.35, p<.001), and delegation skill (r=.34, p<.001), which are the sub-domains of delegation preparedness. Delegation preparedness was correlated significantly with interactions (r=.46, p<.001), task requirement (r=.36, p<.001), professional status (r=.33, p<.001), administration (r=.31, p<.001), and pay (r=.20, p=.026), which are sub-domains of job satisfaction. These results highlight the need for schools and clinical settings to provide continuous education to improve the delegation preparedness for nurses in comprehensive nursing care wards.

This study was aimed to prepare the evidences for establishing policies on nursing manpower by identifying the relationship among delegation level of nursing activities, nursing professionalism and turnover intention in long-term care hospital nurses. The study was a descriptive survey research that used a structured questionnaire. 146 nurses agreed to take part in the research. They worked in six long-term care hospitals located in A and B province. Data were collected from July to August 2016 and analyzed through SPSS 20.0 program, using descriptive statistics, t-test, ANOVA and pearson's correlation coefficients. As a results, first, as for the delegation of nursing activities by long-term care hospital nurses, the levels of delegation of direct nursing activities were 34.63±14.12, and the level of delegation of indirect nursing activities were 1.71±1.75. Second, the mean score of nursing professionalism and the turnover intention of long-term care hospital nurses were 3.62±0.77 and 2.71±0.97, respectively. Third, the delegation of direct nursing activities by long-term care hospital nurses significantly differed depending on the number of nurses in the ward and the number of caregivers in the ward. The delegation of indirect nursing activities significantly differed depending on the number of nurses in the ward, the presence of conflicts and stress related to delegation. Forth, there was no significant correlation of the delegation of nursing activities by long-term care hospital nurses with nursing professionalism and with turnover intention. Most of nursing activities, were delegated to nurse aids, since there were no clear guidelines or legal procedures on nursing activities in long-term care hospital nurses. Therefore it is required to find how to clearly establish positive nursing professionalism and to develop a proper nursing manpower arrangement and the guidelines for the delegation of nursing activities in a long-term care hospital in terms of policy.

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.

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.

Recently, aerospace industries in South Korea are expected to continue to grow due to UAM. Accordingly, certification services for aircraft are expected to increase. As a way to cope with the increase of certification work, one could consider a delegation system that can limitedly delegate the unique role of airworthiness authorities. In this paper, we reviewed regulations of FAA's individual delegation (DER, DAR, DMIR, etc.), the organizational delegation system (ODA), and the EASA's organizational delegation system (DOA, POA). We also reviewed regulations and actual status of delegation system in South Korea. On the basis of these, considering circumstances of aerospace industries in South Korea, we presented a method to introduce certification delegation system gradually and to improve domestic certification regulation.

By proxy signatures, proposed by Mambo, a designated signer can sign original's signature instead of original signer. This paper presents new types of digital proxy signatures called partial delegation with threshold delegation. In proxy signatures for partial delegation with threshold delegation, the proxy signer's power to sign messages is shared. In conclusion, we construct proxy signature schemes satisfying our conditions.

The purpose of this study is to examine the roles and costume of Sodong as shown in the illustration of Choseon Delegation to Japan. Results of the study can be described as below. First, as shown in the illustration, Sodong played roles as Tongin and dancer. As Tongin, Sodong provided services or made errands for his seniors. In the other role, while, Sodong danced to comfort his seniors and show dances of Choseon to Japanese people. Second, Sodong wore Kwaecha over Sochangeui throughout his march with the delegation as Tongin. This is probably because the two clothes made him feel convenient and easily active. In both 1700s and 1800s, meanwhile, Sodong also wore Jikryeong and Cheolik. Third, Sodong wore Kwaecha over Sochangeui, or Danryeong and Nansam all the time when he navigated together with the delegation. When passing through Tsusima into the Japanese mainland, which meant starting international exchanges between Choseon and Japan, Sodong sticked to formality to the utmost by wearing Danryeong and Nansam. Fourth, Sodong wore Kwaecha over Sochangeui when he performed as dancer. The two clothes were also worn by Mudong during outdoor banquets in Choseon at that time. In addition, it is thought that Sodong wore Jikryeong, Danryeong and Nansam like when he marched or navigated together with Choseon Delegation.

Purpose - This study seeks to find out the factors affecting the performance of franchisees from the franchisor's and franchise's intangible assets. In order to explain the process, this study explores the concept of LMX, Relational Capital, and Decision Rights Delegation. Research design, data, and methodology - To verify the proposed hypotheses, a questionnaire survey was conducted for franchise store owners, and to test the hypotheses, structural equation modeling was established. Results - First, franchisor's intangible assets affect the quality of LMX, but don't affect the relational capital. And the quality of LMX affects the relational capital. In addition, "the effect of delegation of decision rights on relational capital" and "the effect of relational capital on franchisee's performance" were significant. However, the effect of delegation of decision rights on franchisee's performance wasn't significant. Second, the intangible assets of the franchise have a positive effect on the quality of the LMX and the degree of delegation of decision rights, and the quality of the LMX has a positive effect on the delegation of decision rights. Conclusions - This study would suggest operational implications for the formation of vertical and horizontal relationships and the cooperation between the main members of the franchise business.
