  • 분산 환경에서 여러 호스트들간의 자료를 공유하는 것은 네트워크에 부하를 줄이고 가용도를 높일 수 있지만 복제된 공유 자료들의 일치성을 유지하는 것이 필요하다. 전통적으로 분산된 공유자료의 일치성을 위해서 무효화방식(invalidate protocol), 갱신방식(update protocol) 그리고 이주방식(migratory protocol)등이 사용되었다. 분산 환경뿐만 아니라 이동컴퓨팅 환경에서도 분산된 호스트들간에 공유자료의 일치성을 유지하기 위해서 적절한 프로토콜을 선택하는 것은 중요하다. 본 논문에서는 이동 컴퓨팅 환경에 효과적으로 적용 할 수 있는 공유자료의 일치성 유지하기 위한 프로토콜을 제안하고 성능 분석을 하였다.

  • [Purpose] Effective nutritional intervention can help reduce the risk of nutritional problems and improve athletic performance in adolescents. The five A's (assess, advise, agree, assist, and arrange) model is widely used as the theoretical framework for advice on nutrition, smoking, drinking, and physical activity and it recommends that practitioners in primary health care promote behavior change to facilitate positive outcomes. This model has also been useful in understanding the underlying processes of behavior change. This study aimed to develop both a novel evidence-based nutritional intervention protocol, rooted in sound nutritional theory, and a customizable nutritional intervention program to support sustainable healthy eating, enhance nutrient intake, and improve athletic performance in adolescent athletes. [Methods] In this study, we adapted the 5 A's behavioral change model and motivational interview to develop a theoretical framework to help adolescent athletes change their behavior and achieve their goals. [Results] During each step of the 5 A's protocol, a customized nutritional intervention protocol was developed by nutrition experts for each of adolescent athletes. Each plan was developed to improve the eating habits of adolescent athletes through group education and counseling. All nutritional counseling sessions were designed to enable participants to apply nutritional knowledge and practical action plans to their training and competition conditions to enable each of them to achieve individual athletic goals and facilitate self-management. [Conclusion] A theoretical and evidence-based nutritional intervention protocol was developed to identify and address obstacles to healthy dietary habits in adolescent athletes. This could be used as the basis for further studies aimed at improving nutrient intake and athletic performance in adolescent athletes.

  • Purpose: This study was designed to develop, to implement and evaluate a fever management nursing protocol for adult patients. Methods: This study was conducted through seven steps following both the guideline development procedures of the Scottish Intercollegiate Guidelines Network and the Model of the Asan Medical Center Evidence-Based Practice, as follows: 1) identifying the clinical needs and composition of the protocol development group; 2) identifying and evaluating the evidence; 3) assessing the level of evidence and grading recommendations; 4) forming a protocol; 5) evaluating the protocol using an expert group validity test and identifying barriers to its implementation; 6) protocol development; and 7) evaluation of practical improvement measures following implementation of the protocol. Results: The evidence-based protocol for fever management in adult patients was completed and includes five domains and 15 items. The protocol had good content validity (CVI=.90) and nursing practice could be improved after implementation of the protocol. Conclusion: This nursing protocol can be used as a guide for nursing in febrile adult patients. We recommend that further guidelines be updated in an interdisciplinary manner in order to foster local adaptation of the best clinical practices.

  • Currently, most IP multicasting applications are implemented based on Any-Source Multicast (ASM) model that supports many to many multicast services. However, it is known that current ASM-based multicast architecture has several deployment problems such as address allocation, lack of access control, and inefficient handling of well-known multicast sources. Source-Specific Multicast (SSM) working group in IETF proposed SSM architecture to overcome the weaknesses of ASM architecture. The architecture of SSM is based on one to many multicast services. Also, in order to provide SSM service, Multicast Listener Discovery Version 2 (MLDv2) protocol should be supported. In this paper, we introduce the architecture of SSM protocol and multicast group management protocol. After that, we present the architecture and implementation of IPv6 SSM and MLDv2 protocols in Linux systems.

  • The goal of this paper is to understand the visual information process and the characteristics of behaviour of the architectural design process using visual protocol analysis through the actual experiment by the architect. The visual protocol analysis is developed on the basis of the theories of the visual information processing model and visual mental image, which can explain visual representation in architectural design process. A protocol study is reported in which the experimental data by architect is analyzed through the protocol analysis method. The whole design process is divided into the stage of 9 tasks which are classified into 18 visual representatiov. The results about visual cognition in cognitive science are reviewed and summarized, and these findings will help understand the architectural design nature.

  • In this paper, for magnetic silence technology of naval vessel, is to make lab deperm system and to evaluate the deperm capacity of naval vessel regarding deperm protocol. Initial permanent magnetic field of naval vessel is magnetized before deperm, having the magnetic field of the same size, to evaluate the deperm capacity regarding a variety of deperm protocol for experimental reliability growth. Current dead time effect of deperm protocol is measured at the different initial current, which are 8A, 6A and 4A respectively. Furthermore, the experiment under the same condition except changing duty cycle into 50% is carried out. As a result, it is possible to compare the six different experiment outcomes. The result shows that the experiment with dead time improve the deperm capacity more than 48.51 percent comparing to the case without dead time.

  • Recently, there ary many researches on local area multichannel network as WDM technology developes. An ideal media access protocol in a multichannel network is one that shows short access delay under low load and high throughput under heavy load. This paper proposed a new media access protocol for WDM passive star coupler network. The proposed one is a random access rpotocol based on reservation. Access delay is short under low load by using random access method, and high throughput is achieved under heavy load by usin greservation access. Analytic model for the performance analysis of the proposed protocol is developed and performance of the proposed protocol is compared with the previous ones. The effect on the performance of the number of the nodes and channels, and the number of transceivers in each node are analyzed.

  • MAC (media access control) bridge is used to interconnect separate LANs and to relay frames between the BLANs (bridged LANs). Bridge architecture consists of MAC entity, MAC relay entity and bridge protocol entity protocol entity and performs learning, filtering and forwarding functions using filtering database. In this paper, we simulate these functions of bridge and the STP (spanning tree protocol). The STP derives an active topology from an arbitrarily connected BLAN. Our simulation model assumes a BLAN consisted of three bridge forming a closed loop. In order to remove the loop, each bridge process exchanges configruation BPDU (bridge protocol data unit0 with other bridge processes connected to the bridge itself. To simulate the communication between bridges, we implement the IPC (inter-process communication) server using message queues. Our simulation results show that the assumed BLAN contains no closed loop and then there is no alternative route and no unnecessary traffic.
