Purpose: This study aimed to investigate the nationwide intention to delegate clinical practice of medical specialists in accordance with the enactment of the scope of practice for advanced practice nurses (APNs). Methods: Data were collected from October to December 2021 using Google Surveys. In total, 147 medical specialists from 12 provinces responded to the survey. The survey questionnaire was categorized into four legislative draft duties, according to the scope of practice (a total of 41 tasks): Twenty-nine tasks on treatments, injects, etc., performed under the guidance of a physician and other activities necessary for medical treatment (treatment domain); two tasks on collaboration and coordination; six tasks on education, counseling, and quality improvement; four regarding other necessary tasks. Participants were asked whether they were willing to delegate the tasks to APN. Results: The intention to delegate tasks to APN was higher for non-invasive tasks such as blood sampling (97.3%) or simple dressing (96.6%). Invasive tasks such as endotracheal tube insertion (10.2%), sampling: bone marrow biopsy & aspiration (23.8%) showed low intention to delegate in the treatment domain. Participants who were older, male, and had more work careers with APN, showed a higher intention to delegate tasks. Conclusion: To prevent confusion in the clinical setting, a clear agreement on the scope of APN practice as APN delegated by physicians should be established. Based on this study, legal practices that APN can perform legally should be established.

As a user in modern societies with the rapid growth of Internet environment and more complicated business flow processes in order to be effective at work and accomplish things on time when the manager of the company went for a business trip, he/she need to delegate his/her signing authorities to someone such that, the delegatee can act as a manager and sign a message on his/her behalf. In order to make the delegation process more secure and authentic, we proposed a secure and efficient identity-based proxy signcryption in cloud data sharing (SE-IDPSC-CS), which provides a secure privilege delegation mechanism for a person to delegate his/her signcryption privilege to his/her proxy agent. Our scheme allows the manager of the company to delegate his/her signcryption privilege to his/her proxy agent and the proxy agent can act as a manager and generate signcrypted messages on his/her behalf using special information called "proxy key". Then, the proxy agent uploads the signcrypted ciphertext to a cloud service provider (CSP) which can only be downloaded, decrypted and verified by an authorized user at any time from any place through the Internet. Finally, the security analysis and experiment result determine that the proposed scheme outperforms previous works in terms of functionalities and computational time.

원서명자의 서명권한을 대리서명자가 수행하도록 지정하는 대리서명기법은 Mambo[1]이래로 많은 연구가 이루어졌으며, 분산네트워크, 그리드 컴퓨팅, 전자 상거래 둥 많은 분야에 응용되고 있다. Araki[6]에서는 기존의 대리서명 기법을 확장하여 다단계 대리서명을 제안하였다 그러나 이 연간결과는 보안상의 취약점이 존재하는 것으로 드러났다. 이 논문에서는 다단계 대리서명을 위한 서명권한 위임 프로토콜을 설계하였다. 이 프로토콜은 보안채널을 요구하지 않으며 권한위임 및 위임수락 부인이 불가능하고 지정된 대리서명자 이외에 제3자에 의한 서명위조가 불가능하며 권한위임기간 만료이전이라도 위임을 철회할 수 있다는 장점을 갖는다.

Purpose: The purpose of this study was to develop and test the validity and reliability of the Korean version of nurses' attitudes toward delegation and preparedness to delegate (APD). Methods: The Korean version of APD was developed through forward-backward translation methods. Internal consistency reliability, criterion validity, and construct validity using exploratory and confirmatory factor analysis were conducted using IBM SPSS Statistics 19 and AMOS 20.0. Survey data were collected from 161 nurses working in 2 general hospitals. Results: The Korean version of APD showed Cronbach's alphas of .68 and .85. Factor loadings of the 8 attitude items on the 3 subscales ranged from .60 to .86 and the 15 preparedness items on the 4 subscales ranged from .47 to .90. The model of 3 subscales for the Korean nurses' attitude toward delegation and the model of 4 subscales for the Korean nurses' preparedness to delegate were both validated by confirmatory factor analysis(NC<3, CFI>.90, RMSEA<.10). Criterion validity compared to job satisfaction showed significant correlation. Conclusion: The findings of this study demonstrate that this modified Korean version of APD is applicable for measuring Korean nurses' attitude toward delegation and preparedness to delegate.

The purpose of this research was fourfold: (a) to identify the use rate of the indirect care interventions performed by nurses, (b) to estimate the time to perform each intervention, (c) to identify the indirect care interventions to be delegated to others, and (d) to determine the level of provider preparation needed to delegate indirect care interventions. The sample consisted of 199 nurses working in three hospitals. The Indirect Care Survey developed by the Iowa Intervention Project team was used for data collection. The instrument was translated to Korean and validated by nurse experts. Each of the 26 indirect care interventions were used several times a day. Four interventions (i.e.. Documentation, Shift Report, Specimen Management, and Transport) were performed several times a day by 50% or more of the nurses. The most frequently used intervention was Documentation, followed by the interventions Shift report. Environmental Management, Transport, and Examination Assistance. The least used intervention was Quality Monitoring, followed by the interventions Order Transcription, Referral, Health Care Information Exchange, Multidisciplinary Care Conference, and Product Evaluation. The intervention taking the most time to per-form was Technology Management (155.3 minutes), followed by the interventions Documentation, (122.2 minutes), Delegation (84.4 minutes), Supply management (83.4 minutes), and Preceptor: Student (79.9 minutes), Overall, the nurses reported that they would not delegate to others the majority of the interventions. More than 50% of the nurses would not delegate 21 interventions. Shift Report would not be delegated by 95% of the nurses and Documentation would not be delegated by 92% of the nurses. Caregiver Support would be delegated by 68% of the nurses to family. Three interventions (i.e.. Environmental Management, Examination Assistance, and Transport) would be delegated by more than 50% of the nurses to Nursing Assistant. This study will contributes to determining costs of nursing services and enhancing quality of nursing care. Replication study will be needed with large sample.

Purpose: To identify the clinical role of Advanced Practice Nurses (APN), and evaluate how other medical personnel perceive their work(difficulty, importance). Methods: A questionnaire survey was performed with 277 health care providers (APN 52, nurses 88, and medical doctors 137 [professors 51, fellows 44, & residents 42]) in a single, tertiary hospital. The questionnaire was categorized into 6 domains (total 40 tasks): 6 tasks on identifying health issues (A); 3 tasks on prescribing and conducting diagnostic tests (D); 18 tasks on disease treatment (T); 4 tasks regarding prescribing medicine (M); 3 tasks regarding medical collaboration (C); 6 tasks regarding patient education (E). The survey measured the frequency, difficulty, and importance of APN's clinical tasks, and evaluated the willingness of authorizing clinical tasks to APN. Results: The most frequent tasks for APN were A domain, lowest were T domain. The scores for perceived job difficulty were lower than those for job importance in all groups. The proportion of willingness to legally delegate clinical practices to APN was higher in A and E domains, but lower in D and T domains. However, professors, who spent the most time with APN, showed a higher willingness to legally delegate clinical practice. The participants favored medical doctors as substitutes for tasks which were not legislated for delegated job performance. Conclusion: In this study identified clinical roles that medical doctors considered possible for legal delegation to APN were identified. The results can be used as evidence for the legalization of the practice of APN.

RBAC은 시스템 자원의 안전한 관리를 위한 접근 통제 메커니즘이며 네트워크에서 보안 관리를 위한 비용과 복잡성을 감소 시켜주기 때문에 특히 상업적인 분야에서 관심을 끌고 있는 기술이다. RBAC에 대한 많은 연구가 진행되고 있지만 그 중에서도 현재 가장 시급하게 대두되고 있는 부분은 역할 위임에 관한 문제이다. 실제 조직에서 직원의 휴가나 병가 또는 기타 이유로 한 사람의 역할을 다른 사람에게 위임해야 될 필요성이 존재한다. 그러나 현재 NIST의 RBAC 표준은 이러한 역할 위임에 관한 속성을 정의하고 있지 않다. 본 논문에서는 효율적인 접근통제를 위해 위임자가 역할과 권한의 일부를 피 위임자에게 위임할 수 있는 RBAC 모델을 제시하였다.

본 연구는 환경분쟁에서 주민과 기업이 각각 자신의 대리인과 조건부로 계약을 하는 대리인 모형을 설정하고, 비대칭배상 제도의 효과를 분석한다. 본 연구의 주요 결과는 다음과 같다. (1) 비대칭배상은 주민의 기대잉여를 증가시켜 환경분쟁의 빈도를 높인다. (2) 비대칭배상은 법정에서의 기대차액을 감소시켜 합리적인 분쟁당사자의 화해가능성을 높인다. (3) 이러한 화해는 총법정노력을 감소시킴으로써 사회적 비용이 감소한다. (4) 분쟁이 화해에 이르지 않고 법정소송으로 귀결되는 경우, 대리인들의 총법정노력이 증가한다. 이 경우에는 Tullock (1967, 1980)이 제시한 지대낭비의 관점에서 사회적 비용이 증가하게 된다.
