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.

BICC protocol is a relay protocol adaptable to ATM and IP based core networks compared to ISUP protocol to TDM networks. Using BICC protocol, multi-rate bearer traffic such as voice and video can flow in the relay core networks. BICC protocol is standardized as WCDMA circuit switching networks in 3GPP Release 4. Thus KTF is now operating core networks using BICC protocol. In this paper, we describe the background and characteristics of BICC protocol. We also provide the status of KTF WCDMA core networks using BICC. To show the efficiency of BICC protocol an analytical simulation is given in which the results can be expected by intuitive observation.

Purpose: This study was done to develop a pain management protocol for nursing home patients with dementia and to examine effects of the protocol on pain assessments and interventions by the nurses and on pain relief signs in the patients. Method: The six steps in the protocol development and the examination of effect are outlined. Three rounds using the Delphi technique and one group pretest-posttest design experiment were developed. Design issues, such as sample selection and sample size, are addressed in relation to the study protocol. Results: After implementation of the pain management protocol, there were significant changes nursing actions including frequency of number of physical examinations, utilization of pain assessment tools, and request to doctors for discomfort management and there were significant changes in frequency in the number of verbal and physical expressions of pain, and emotional patterns. Conclusion: This is the first pain management protocol for patients with dementia in Korea. However, more study will be needed to determine the methodological strength and necessary revisions for the protocol.

In this paper a cross layer protocol, referred to as an underwater ad-hoc communication (UAC) protocol, is proposed for underwater acoustic networks (UANets). An underwater node (UN), which tries to transfer data to another UN or a buoy in ad-hoc manner, can access channel as well as determine routing path by employing the UAC protocol. The channel access, route determination, and reliable data transfer are designed being adaptive to underwater environments. In addition, we propose both UN and packet architectures in order to efficiently implement the UAC protocol for UANets.

As a very important part in development of the protocol, verifications for developed protocol specification are complementary techniques that are used to increase the level of confidence in the system functions by their specifications. Using the informal method for specifying the protocol, some ambiguity may be contained therein. This indwelling ambiguity in control systems can cause the occurrence of accidents, especially in the case of safety-critical systems. To clear the vagueness contained in the designed protocol, we use the LTS (Labeled Transition System) model to design the protocol for railway signaling. And then, we verify the safety and the liveness properties formally through the model checking method. The modal ${\mu}$-calculus, which is an expressive method of temporal logic, has been applied to the model checking method. We verify the safety and liveness properties of Korean standard protocol for railway signaling systems. To perform automatic verification of the safety and liveness properties of the designed protocol, a communication verification tool is implemented. The developed tools are implemented by C++ language under Windows XP. It is expected to increase the safety and reliability of communication protocol for signaling systems by using the developed communication verification tool.

Purpose: The purpose of this study was to develop a blood glucose control protocol for medical intensive care unit (ICU) patients. Methods: The blood glucose control protocol was developed through the following process: selection of preliminary protocols, clinical application, and evaluation. The clinical validity of the protocol was measured by application, along with examination of the effects of the Yale and the Mayo blood glucose protocols. Seventeen medical ICU adults patients whose blood glucose levels exceeded 200 mg/dL consecutively participated in the study. The development protocol was evaluated by an expert group. Results: Incidence of normal blood glucose levels (p=.041) increased significantly in the Yale protocol application group. Also, incidence of severe hyperglycemia (p=.029) decreased significantly and time to target range of glucose (p=.023) decreased significantly after application of the Yale protocol. However, there was no significant difference in incidence of hypoglycemia (p=.666) between three groups. Conclusion: Using the developed protocol as a basis for the modified Yale protocol was found to be effective in improving the state of blood glucose control for medical ICU patients and is expected to be used for nursing intervention in critical care.

Video is principal information that facilitates commander's immediate command decision. Due to fading characteristics of radio link, however, it is difficult to stably transmit video in a multi-hop wireless environment. In this paper, we propose a MANET structure composed of a link adaptive routing protocol and a TDMA MAC protocol to stably transmit video traffic in a ultra-narrowband video streaming network. The routing protocol can adapt to link state change and select a stable route. The TDMA protocol enables collision-free video transmission to a destination using multi-hop dynamic resource allocation. As a result of simulation, the proposed MANET structure shows better video transmission performance than proposed MANET structure without link quality adaption, AODV with CSMA/CA, and OLSR with CSMA/CA structures.
