Most of all countries have a governmental system for regulating the certification of nursing. In Korea, certification of advanced practice nurse(APN) is statuary regulation under supervision of government. In this article, the writers discuss the legal characters and effects of certification and regulatory body for certification and suggest the new regulatory system. The advanced practitioner may be recognize "new" health provider in the future. The nursing specialist have right to use title and practice expanded role. It's different things with physicians certification. The regulatory body is important because certification protected the title and empower APN authorize of expanded role. The certification of nursing is closely connected with public interest. The Korea government delegate power of national examination to private institute. To improve utility and publicity of certification system, we suggest that statutory empower the certification authority to public institute which composed with nursing professionals.

Computing today is becoming ubiquitous. In such ubiquitous computing environments, entities expect to access resources and services at any time from anywhere. Therefore, the question rises of how to establish trust relationship in previously unknown devices or resources with such environment. After reviewing a model to delegate trust to communicating entities in ubiquitous environment and its security problems, we present a new model for secure delegation over communication entities. We adopt two-party signature scheme as cryptographic primitives. Additionally, we apply threshold cryptosystems to our model for more secure enhancement.

C＃ 언어로 작성된 프로그램을 정적으로 분할할 때 기존의 객체 지향 프로그램에 이용하던 방법을 일반적으로 적용할 수 있다. 그러나 기존의 두 경로 그래프 도달 가능성 분할 알고리즘을 적용하였을 때 프로시져들 간의 전지적인 종속 관계를 표현하는 요약 간선만을 이용하면 두 번째 경로에서 역추적 할 때 모호성이 발생한다. 이러한 모호성 C＃의 이벤트, 델리게이트(delegate)들과 메소드의 다형적 호출 관계에서 발생될 수 있다. 본 논문은 호출된 프로시져의 호출하는 문맥을 설명하기 위하여 호출 지점에서 요약간선 및 경로 간선을 이용하여 C＃에서 다형적 호출에 대한 시스템 종속성 그래프(system dependence graph)에 대한 새로운 표현을 제안한다. 이 방법은 다형적 호출에서 발생하는 모호성을 해결할 수 있다.

블록체인은 탈중앙화된 신뢰 기반 분산 데이터베이스로 높은 신뢰성과 보안성을 제공하지만 기존의 블록체인들은 확장성이 떨어진다는 문제를 지닌다. 이 문제를 해결하기 위해 기존의 방법들은 소수의 대표노드들을 선출하여 합의 과정을 간소화 하려 하였다. 그러나 이러한 시도는 대표 노드를 선출하기 위해 지분 기반 투표 방식을 사용하기 때문에 많은 지분을 가진 노드들에게 권한이 집중될 수 있다는 한계를 갖는다. 본 연구는 이러한 한계점을 해결한 대표노드 선출/해임 모델을 소개한다. 제안 방법은 Raft 의 투표 알고리즘을 확장하여 대표노드의 공정한 선출과 대표노드의 부적절한 행위를 예방한다. 제안 방법은 모델 검증을 통해 도달 가능성, 안전성, 활동성이 확인되었다.

Purpose - The purpose of this paper is to develop a tractable general-equilibrium model of examining the impact of human resource management on intra-industry trade. Commonly, managers of Korean firms are promoted internally. It necessitates a study of human resource management and its impact on an industrial equilibrium. Design/methodology - This paper relies on theoretical analysis. We build a model in firms are hierarchical; an entrepreneur, managers, and workers. All individuals have heterogeneous managerial talents, which are the main source of managerial quality. Firms search talents for prospect managers, and eventually delegate them to supervise workers. The searching incurs a sunk cost. Findings - Our finding is as follows. Country 1, relatively abundant of managerial talents, can gain more from trade than Country 2, relatively scarce of managerial talents. This is because the higher searching cost leads to the lower survival rate of firms in Country 2. Implicatively, good jobs are destroyed, and aggregate income falls in Country 2. Originality/value - According to our study, relative abundance of managerial talents affects distribution of firm size and determines trade gain. This study can contribute to the literature of organization management and trade.

Achievements of Korean delegate students who attend on the 9th International Biology Olympiad(IBO) were compared with those of IBO participants for the 4th, 5th and 7th theoretical tests. It was predicted that four Korean delegates won medals in the 9th IBO on the basis of the average percentages of correct answer and the shifting patterns of achievement. And achievemens of four delegates during delegates training period were compared with that in the 9th IBO. Mean perecntages of theoretical part of them were 78.15%, 77.16%, 80.97% and 76.99% respectively, and total mean percentage was 78.32%. Their achievement was level for silver medalist. It was 86.56% on the average that they had achieved in the 9th IBO. This result was more than achievement in delegates training. Their percentages of achievement order were 90.84%, 97.71%, 82.44% and 70.99% respectively. One of them won gold medal and the others won silver medals. It was needed to develop effective teaching program for biology gifted-students and training preparing for IBO.

Proxy signatures is a signature scheme that an original signer delegates one's signature capability to a proxy signer, and then the proxy signer creates a signature on behalf of the original signer. Delegation of authority is a common practice in the real world, in particular, it happens naturally in hierarchical groups such as company, bank and army, etc. In this paper, we propose a new dynamic multi-proxy signature scheme allowing repetitive delegations in a hierarchical group. We adopt multi-proxy signatures to enhance the security of proxy signature. In multi-proxy signatures, plural proxy signers can generate a valid proxy signature collectively on behalf of one original signer. In our scheme, the proxy group is not fixed but constructed dynamically according to some situations. Delegations are processed from higher level to lower level in the hierarchy using delegation tickets. When the original signer wants to delegate one's signature authority, the original signer generates a delegation ticket based on secret sharing and Diffie-Hellman problems. The delegation ticket is shared among proxy signers and then all the proxy signers can generate a valid proxy signature collectively by reconstructing the original signer's delegation ticket. If a certain proxy signer can not attend the proxy signature generating protocol, the proxy signer can also delegate repetitively his partial signature authority to the lower level participants, and then the proxies are constructed dynamically.

This essay is for a study on the survey of buddhist cultural literary document about the Southeast Asia by Nanqishu(南齊書), Liangshu(梁書), Chiu T'angshu(舊唐書), Hsin T'ang shu(新唐書) which are included in the Chinese Official History and Jí-shénzhōu-sānbăo-găntōng-lù(集神州三寶感通錄), Weioshu Shilao Ji (魏書 釋老志). These documents allows us to imagine next some historical states. First, these documents are recording this area, especially Funan, as a plentiful diggings of gold, silver, tin, copper, etc. These are important materials for gilt bronze sculptures. Further, this local produced gold called 'Yangmai(楊邁)' is recognized as same as Zĭmòjīn(紫磨金) in china, and these documents explains the process of producing the bronze images and golden ornaments in Southeast Asia. Specially, this plentiful materials leads them to make a 10 wei(圍) tall golden-silver image which worshiped as hindu god or sometimes buddhist images. Second, Vietnam and Funan in Northern and Southern Dynasty periods were in antagonistic relationship not only in the political but also in religious between Vietnamese Hinduism and Funan's Buddhism. Under this situation, the monk Nagaxian(那伽仙) who had came from India was accredited to Southern Qi court as a delegate to build a good relationship by the common religion Buddhism. It means the Buddhism of Southeast Asia also took a role of diplomacy. Third, these documents proved the active Southeast Asian cultural exchange in early 3th century. At this time, Funan delegate Suwu(蘇物) visited the court of Kushan Dynasty in India and he is seemed to travel the city of Pātaliputra. It oppressed us to extend our outlook which have been restricted in the relationship between Southern india and Southeast Asia to more broaden area. In addition, the buddhist art of Southern India and Bodhgaya temple was imported to Southeast Asia directly to send to Southern China. For example, the wooden buddha image, Bodhgaya stupa image, and Sri Lanka style's buddha images are looked be introduced to Southern China at this time throughout the Southeast Asia. At last, we got to know that the court music of Kucha in the northern silk route was imported to the Southeast Asia in early middle age. Even it may be introduced by China, but this document is very important to make the surmise is not unreasonable that the buddhist culture of northern silk route imported to the Southeast Asia accompanied with Kucha music. The buddha images in Gandharan style which are excavated from some site of Southeast Asia may demonstrate this literary sources is authentic.

In this study, we have experimented with 9 players at the national delegate level. Although there were some differences in the average effects of 3 types of one-two straight movements after the application of wheel axle, there were no statistical differences in the case of surface reacting forces, electromyograms, and impact forces. When the right fist was impacted using the one-two straight movements and the wheel axle was applied with 3 segmentations, high impact forces were obtained for the pronation in the following order-72.01 $m/s^2$ (type 2), 70.93 $m/s^2$ (type 3), and 58.19 $m/s^2$ (type 1). Higher values of the surface reacting force were found for type 1 that did not exhibit pronation in the left foot, whereas in the case of the vertical direction of the right foot, type 2 with pronation exhibited higher values and impact forces. In the right electromyogram, high impact forces due to the activation of the muscular electric potential were obtained for lumbar erector (LE) spinae and triceps brachii (TB) with type 1; LE spina, latissimus dosi (LD), and upper trapezius (UT) with type 2; and brachioradialis (BR), UT, and rectus abdominal (RA) with type 3. Due to pronation and complex motions of the 3 pronation segmentations, the efficiency was higher for impacts due to one-two straight movements.
