Spinal cord injury patients need rehabilitation after the acute stage. They should be cared for at home to decrease hospitalization. Home care nurses play an important role in making spinal cord injury patients who have physical. and psychosocial problems do their best. For effective care, home care nurses need standardized nursing intervention protocols for spinal cord injury patients, but they are rarely developed. Therefore, this study was conducted to develop home care nursing protocols, based on NIC, that are applicable to spinal cord injury patients at home. Forty home care nursing charts of spinal cord injury patients registered in a home care nursing agency from July 1st, 1994 to August 31st, 1999 in S city were analyzed. Fifteen home care nurses participated in this study as a user validity validation group, The results of this study are as follows. 1. Fifteen nursing diagnoses were classified through the frequency analysis of home care nursing charts and previous literature for 40 spinal cord injury patients: altered urinary elimination, constipation, high risk for impaired skin integrity, chronic pain, impaired skin integrity, impaired social interaction, knowledge deficit, bowel incontinence, high risk for injury, altered role performance, care giver role strain, impaired physical mobility, sexual dysfunction, dysreflexia, and ineffective breathing pattern. 2. Based on validation by experts and user validities, 93 nursing interventions which were above ICV(Index of Content Validity) .80 were chosen. 3. Nursing intervention protocols which showed above ICV .80 were developed.

Voice of IP(VoIP) technology Provides voice service as well as data service via Internet. It has been a promising technology as Internet grows fast and the requirements are increasing. Among the standardized protocols for VoIP, H.323 has been one of the most developed technologies and widely used. Recently, the requirements for standardization of inter-domain interoperability is raised, since it has been developed by focusing on intra-domain service. To meet such requirements, IMTC(International Multimedia Telecommunications Consortium. Inc.) and VoIP Forum have elaborated on interoperability standard based on H.323, respectively in international and domestic markets. In this paper, we describe the call model and specify required functionalities of inter-domain interoperability based on H.323.

The RR protocole, proposed in IETF mip6 WG and standardized by RFC 3775 at lune 2004, send a message 'Binding Update' that express MN's location information to CN safety and update location information. Standard RR protocole has some problems with initiating the protocol by the MN; it causes to increases in communication load in the home network, to increases communication delay between MN and CN. Also, is connoting vulnerability to against attacker who are on the path between CN and HA in security aspect. This paper proposes doing to delegate MN's location information update rights by HA new location information update method. That is, When update MN's location information to HA, Using MN's private key signed location information certificate use and this certificate using method that HA uses MN's location information at update to CN be. It decreases the route optimization overhead by reducing the number of messages as well as the using location information update time. Also, remove security weakness about against attacker who are on the path between CN and HA.

The protection switching technology is widely adopted in the fiber-optical transmission equipments based on TDM(Time Division Multiplexing), such as PDH, SDH/SONET. A variety of protection switching algorithms for Ethernet networks and the progress of standardization are summarized in the document. There are several kinds of protection switching algorithms for Ethernet networks, such as STP, RSTP, MSTP and etc. However, since Ethernet signal move through detour route, it causes much time to recover. Accordingly, it is difficult to secure a usability of Ethernet networks and QOS(Quality of Service). Also, if the protection switching protocol standardized by IEEE and ITU-T is used, it remains a inherent network switching time for protection. Therefore, a specific protection switching algorithm for Ethernet are needed for seamless and stable operation of Ethernet networks service for Distribution Automation System(DAS). A reliable protection algorithm with no switching delay time is very important to implement Self-healing service for DAS. This study of FPGA based protection switching algorithm for Ethernet networks shows that in case of faults occurrence on distribution power network, immediate fault isolation and restoration are conducted through interaction with distribution equipments using P2P(Peer to Peer) communication for protection coordination. It is concluded that FPGA based protection switching algorithm for Ethernet networks available 0ms switching time is crucial technology to secure reliability of DAS.

Explosive growth of smartphone-based mobile nodes has increased exponentially the mobile data traffic on the Internet. To reduce the traffic load on the network and to support the seamless mobility of the mobile nodes, the IETF and 3GPP have standardized a number of mobility management mechanisms. More recently, they are making an effort to find some schemes to distribute the networking systems that involve in the mobility management in order to assure the scalability and the reliability of the network. In IETF, DMM concept for the distributed mobility management on the Internet is being discussed. Specifically, the DMM can be classified into the partially distributed management and fully distributed management. In this paper, we propose a fully distributed mobility management scheme (FuDMM) on PMIPv6-based network by applying the extended NDP. We also present the performance of FuDMM using the comparative analysis with the existing ones.

Objectives : This study was aimed to find the motivation and satisfaction of subjects who participated in acupuncture and moxibustion clinical trials and to suggest ways to improve clinical trial management. Methods : We conducted a survey and collected the data of 233 subjects of acupuncture and moxibustion clinical trials from 6 university hospitals. Results : For all 233 subjects, the mean of the total satisfaction score was 4.07 (perfect score 5.0), and the score was particularly high in aspects of the investigator and clinical research coordinator, but low in the site and sponsor aspects. There were no differences in the satisfaction degree with general characteristics. The satisfaction degree of the acupuncture and moxibustion clinical trials was strong positive correlated with participation benefits(r=0.595) and easy contact with the research team (r=0.500). Conclusions : Most subjects showed positive perception and interest in the clinical trials. Future studies should investigate how personal factors influence the satisfaction of subjects, should identify a specific classification criterion, and create a standardized protocol for the clinical trials.

PURPOSE. To describe and characterize the surface topography and cleanliness of CAD/CAM manufactured zirconia abutments after steaming and ultrasonic cleaning. MATERIALS AND METHODS. A total of 12 ceramic CAD/CAM implant abutments of various manufacturers were produced and randomly divided into two groups of six samples each (control and test group). Four two-piece hybrid abutments and two one-piece abutments made of zirconium-dioxide were assessed per each group. In the control group, cleaning by steam was performed. The test group underwent an ultrasonic cleaning procedure with acetone, ethyl alcohol and antibacterial solution. Groups were subjected to scanning electron microscope (SEM) analysis and Energy-dispersive X-ray spectroscopy (EDX) to verify and characterize contaminant chemical characterization non- quantitatively. RESULTS. All zirconia CAD/CAM abutments in the present study displayed production-induced wear particles, debris as well as organic and inorganic contaminants. The abutments of the test group showed reduction of surface contamination after undergoing an ultrasonic cleaning procedure. However, an absolute removal of pollutants could not be achieved. CONCLUSION. The presence of debris on the transmucosal surface of CAD/CAM zirconia abutments of various manufacturers was confirmed. Within the limits of the study design, the results suggest that a defined ultrasonic cleaning process can be advantageously employed to reduce such debris, thus, supposedly enhancing soft tissue healing. Although the adverse long-term influence of abutment contamination on the biological stability of peri-implant tissues has been evidenced, a standardized and validated polishing and cleaning protocol still has to be implemented.

ETSI M2M Platforms provide general infra services for machine-to-machine communication. In this paper, we propose a service-level integration methodology which can integrate a ETSI M2M platform with heterogeneous web applications based on WSDL 2.0. Considered heterogeneous web applications are the ones that use SOAP, HTTP and CoAP protocols for inter-communication. The proposed WSDL 2.0-based service-level integration methodology includes the followings; (1) We present a method of how to describe standardized M2M platform service interfaces into a WSDL 2.0 document. (2) A proposed web client generator is used to generates SOAP, HTTP and CoAP client codes from the WDSL 2.0 document. (3) We propose protocol conversion proxies which translate protocols into other protocols in web service run-time.

For the sharing and exchange of information between medical clinics, the clinical document has to be built on a standardized protocol such as a HL7-CDA. But it is difficult to exchange information between medical clinics because clinical document such as electronic medical record that include text and image, have different structure of document and type of expression. In this paper, we propose the electronic medical record system based on HL7-CDA that can share and exchange clinical information between medical institute. For this purpose, we have to design the schema of the clinical document architecture after we select the essential items of medical record and define templates. The proposed system can minimize integrating process and save parsing time when clinical information exchange and refer, by converting electronic medical record to base64 encoding scheme and integrate it in a XML document.

Sewer condition assessment involves the determination of defective points and status of aged sewers by a CCTV inspection according to the standard manual. Therefore, it is important to establish a reliable and effective standard manual for identifying the sewer defect. In this study, analytic reviews of the CCTV inspection manuals of the UK, New Zealand, Canada and South Korea were performed in order to compare the defect codes and the protocols of condition assessment. Through this, we also established the standardized method for defect code and revised the calculation method of assigning the condition grade. Analyses of the types and frequencies of sewer defects that obtained by CCTV inspection of 7000 case results, showed that the joint defect and lateral defect were the most frequent defects that occurred in Korea. Some defect codes are found to be modified because those did not occur at all. This study includes a proposed new sewer defect codes based on sewer characteristics.
