Purpose: This study aimed to investigate the difference between primary caregivers' self-efficacy and coping strategy according to the communication styles of home care nurses. Methods: Data were collected from 123 primary caregivers of patients who were registered at a home care nursing center in D city and who had been receiving home care for more than 3 months from January 1 to February 27, 2018. The questionnaire included items on communication style, self-efficacy, and stress coping strategy. The data were analyzed using descriptive statistics, t-test, and ANOVA. Results: Regarding primary caregivers' self-efficacy in terms of communication style, the caregivers showed higher efficacy in providing informative and friendly communication (F=14.07, p=.001). Regarding home care nurses' communication style and the stress coping strategy of the primary caregivers, the informative-friendly communication style was adopted the most for the problem-solving coping strategy (F=7.17, p=.001). Regarding the social support-seeking coping, home care nurses' friendly communication style was the most adopted (F=4.40, p=.014). Conclusion: This study suggests that home care nurses will plan to provide informative and friendly communication-oriented nursing care, and to improve self-efficacy and positively influence the coping method by using the communication styles appropriate to the state of the primary caregiver.

Objectives: In this study, dental hygienists' perceptions of dental hygienists' communication and general public's mutual perceptions were compared to seek development directions and plans for improving dental hygienists' communication skills, and furthermore, communication to increase satisfaction between the general public and dental hygienists. This study was conducted to provide basic data on the development and direction of competency improvement education. Methods: From April 1 to April 31, 2023, a survey was conducted through an online link for the general public with dental treatment experience and dental hygienists currently working at dentists in Gwangju and Jeonnam. A total of 258 questionnaires were collected. Independence t-test and paired t-test were performed using SPSS Statistics (ver. 21.0; IBM Corp., Armonk, NY, USA) Results: As a result of analyzing the accuracy of the communication ability of dental hygienists, from the dental hygienist's point of view, general publics perceived that the dental hygienist's underestimation of their own communication ability was actually lower than the dental hygienist's underestimated communication ability. From the general public's point of view, dental hygienists overestimated their communication ability. In fact, dental hygienists perceived their general publics as higher than general public's overestimated communication ability. Conclusions: Based on these results, it is necessary to develop education and operate various educational programs to improve the communication skills of dental hygienists, and to rethink educational accessibility to increase participation in education and to publicize the professionalism of dental hygienists.

Total laryngectomy is the most useful procedure tor advanced laryngopharyngeal cancer, but it remains the major problem such as loss of voice. Voice restoration is essential for every patients who undergo a total laryngectomy. Ideal voice rehabilitation methods can resolve three factors. First, every laryngectomee can produce voice sufficient for communication, second every patient should be allowed to use both hands freely during phonation, and last, the voice restoration methods should be easy and safe without complication during and after treatment. Among various voice rehabilitation procedures during or after total laryngectomy, it can be divided electronic and pneumatic methods. In pneumatic methods, there are also divided both pulmonary air and non-pulmonary air methods. The non-pulmonary air methods include esophageal speech, buccal speech, and pharyngeal speech. Pulmonary air methods are divided into surgical and non-surgical such as pneumatic speech aid. In the surgical methods, there are neoglottic operation, tracheopharyngeal shunt, and tracheopharyngeal shunt operations. Recently, tracheoesophageal shunt with or without prosthesis are being recognized the most effective method. Blom-Singer low pressure prosthesis, Panje button, and Provox are well known types of prosthesis in the tracheoesophageal shunt operation. Amatsu method is a kind of famous tracheoesophageal shunt method without using prosthesis. Authors tried to review the published articles for evaluation of effectiveness and problems of tracheoesophageal shunt operation with or without prosthesis. In conclusion, indwelling type of prosthesis and pharyngeal myotomy and plexus neurectomy are recommended for higher success rate during tracheoesophageal puncture procedure. More over, Amatsu method is also one of the recommended voice rehabilitation procedure during total laryngectomy. In this situation, pharyngeal myotomy and plexus neurectomy may be helpful for better fluent communication.

Mobile users want to be provided with undisrupted network services when they navigate on the Next-Generation (NG) wireless networks. For that, interlocking with a heterogeneous network is important, but there have been few studies on the method for guaranteeing global mobility. Thus, this paper proposes the Proxy-LMA technique, the mobile IP-based global inter-networking system, to enhance global mobility and interoperability within the Next-Generation (NG) network environment. The purpose of the proposed Proxy-LMA system is to expand the boundary of the mobility with regards to the existing mobility management protocol (PMIPv6 and MIPv6) in order to guarantee global mobility and interoperability within the heterogeneous network environment. The results of the performance evaluation showed that the proposed Proxy-LMA system was more efficient than other methods from the standpoint of signaling cost and delay in the heterogeneous network environment.

Purpose: The purpose of this study was to investigate factors associated with drug misuse behaviors among polypharmacy elderly. Methods: This was a cross-sectional survey. Participants consisted of 116 polypharmacy elderly who were taking 5 or more medications each day. Data were collected via face to face interviews. Data were analyzed using the PASW 18.0 program. Data concerning predisposing factor (knowledge, benefit), enabling factor (communication with health care provider), and need factor (perceived health status, number of disease) were collected. Results: The total mean score of drug misuse behaviors among polypharmacy elderly was 3.04 out of 10 points. Communication with health care provider, perceived health status, and knowledge were found to be significantly correlated with drug misuse behaviors. In stepwise multiple regression analysis, a total of 42% of the variance in drug misuse behaviors was accounted for communication with health care provider, perceived health status, and knowledge. Conclusion: Therefore, education program for improving communication with health care provider, and knowledge should be designed and provided for polypharmacy elderly.

Most networks for automation are tuned to an expected traffic at their design stage. During their actual operations, however, the networks experience considerable changes in traffic from time to time. These traffic changes caused by common events like machine failure and production schedule change may adversely affect the network performance and, in turn, the performance of the connected devices. This paper presents communication delay model for Profibus token passing protocol, and introduces TTR selection methods to maintain a uniform level of network performance at all stations under changing network traffic.

New computing paradigm in ubiquitous computing environments is revolutionizing the way people interact with computers, services and the surrounding physical spaces. In order to provide stronger authentication, MIST proposed an authentication framework for ubiquitous computing environments and assigned confidence values to some authentication methods to facility the combining. However, the assigned confidence values lack sufficient evidence. In this paper reliable confidence values for each authentication method used in MIST is proposed. These confidence values can combine multiple confidence values in some manner, producing a more accurate net confidence value. Authentication entities with confidence values allows the authentication framework to blond nicely into ubiquitous computing environments.

The necessity for services of emergency communication systems to be uninterrupted and reliable has brought forward strict requirements for express software upgrades of base stations. Based on reconfigurability technology, this paper presents a protocol reconfiguration scheme for emergency communication base stations. By introducing the concept of 'local safe state,' the proposed scheme could make the updating and replacement of the protocol software flexible and maintain interactions during the updating procedure to achieve seamless system upgrades. Further, taking TETRA protocol stack and VxWorks operating system as an example, specific processes and realization methods of reconfiguration are proposed in this paper, along with the measurements of the factors impacting on the system performance. Simulation results show that, compared with traditional technology, the method proposed significantly improves the system efficiency and does not interrupt system services.
