This study investigated consumer convergence preferences for healthcare information service in social media using the multi-attribute utility theory. The multi-attribute utility theory is an approach for compositional modeling attributes wherein researchers compute the overall service utility by aggregating the evaluation results for attribute values. We found that healthcare information service consumers in social media evaluate the service preference through the multi attributes - Update, Cost, Usefulness, Usability, Reliability. And the study shows that individual preference by estimating weight of each attribute in the services influences the service use intention. So we believe that estimating preferences with multi-attribute utility theory will predict business success of the services in a new media, and for a successful business of the social media services marketers should assess the consumer's preference using the multi-attributes.

Hospital medical services are making great efforts to provide prompt medical services to patients or improve the quality of medical services by convergence patient's healthcare information. However, recent research suggests problems about safety and efficiency when trying to transmit patient's healthcare information to hospital server via radio and wireless. In this paper, we propose a color model - based patient authentication key establishment protocol method to securely transmit patient healthcare information. The proposed method extracts randomly three color information used in the color model and vectorizes the extracted arbitrary information to obtain the key information required for user authentication as the sum of orthogonal vectors to improve the efficiency. In addition, the proposed method can securely generate key information used for user authentication without using an additional encryption algorithm. In performance evaluation result, proposed method shows that the server processing time of the sensed information is 8.1% higher than the existing method and 7.7% lower than the existing method.

Augmented reality smart-glass enables healthcare providers to use patient and their care related information without interference of workflow. In addition, augmented reality smart-glass simulation had advantages in improving competency via remote collaboration and real-time information sharing. This study investigated perception and attitude regarding augmented reality smart glass based healthcare simulation on three different groups of healthcare major students, computer major students, developers and faculties. Using convenience sampling method, data were obtained from 95 participants and statistical analysis were performed using SPSS 25.0. Developer and faculty group showed the highest scores, followed by healthcare major students. There was the high expectation on augmented reality smart-glass for skill acquisition and the high performance and big screen were essential features of device. The findings of this study revealed that differences between healthcare and computer major students exist and strategies to reduce those gaps are required to adopt augmented reality smart glass in healthcare settings.

This study aims to identify the moderating effect of patient activation in relation between trust in healthcare professionals and shared decision making in patients with diabetes mellitus. The participants were 186 patients who received treatment for diabetes at the department of endocrinology in the tertiary hospital located in Daejeon and consented to participate in our survey. The results of this study were a significant interaction between trust in healthcare professionals(β=0.32, p=.045) and patient activation(β=0.32, p=.024) was associated with shared decision making. The patient activation had a moderating effect between trust in healthcare professionals and shared decision making in patients with diabetes mellitus(β=0.25, p=.019). Therefore, it is necessary to assess trust in healthcare professionals to improve negative awareness of healthcare professionals and strengthen trust in them. In addition, to promote participation in shared decision making, it is necessary to develop a convergent program to focus patient activation.

Smart environment of health information technology, u-Healthcare architecture, ad-hoc networking and wireless communications environment are major factors that increase vulnerability of u-healthcare information systems. Traffic domain is the concept of network route that identifies the u-Healthcare information systems area as the traffic passing and security technologies application. The criterion of division is an area requiring the application of security technology. u-Healthcare information system domains are derived from the intranet section. the public switched network infrastructure, and networking sectors. Domains of health information systems are separated by domain vulnerability reason. In this study, domain-specific security vulnerability assessment system based on the USN in u-Healthcare system is derived. The model used in this study suggests how to establish more effective measurement USN-based health information network security vulnerability which has been vague until now.

As industries converge in recent years, the impact of the use of convergence tools among industries on the security of the organization is increasing. However, organizational members lack the ability to adapt to introduction of new system because they are operating business around existing systems, and thus, security considerations are an environment that will inevitably emerge as a follow-up priority. In this study, we studied cost-effective options for factors that should be considered first in order to establish a security system for small and medium-sized healthcare institutions in the healthcare convergence industry. Specifically, the current legal system was considered and the security status was analyzed through prior research, and the necessary security solution/system was derived from small and medium-sized healthcare institutions. In addition, it analyzed relative priorities for cost-efficient deployment of security systems to those involved in small and medium-sized healthcare institutions in actual business environments and presented measures to establish a overall security.

In recent, the advancement of wearable devices and wireless body area networking technologies motivate researchers to pay attention to remote healthcare system for monitoring patients health and disease progression effectively. However, in order to implement a practical remote healthcare system, we must consider the security and privacy of patient's personal health information transmitted to healthcare servers through the network. Hence, in this paper, we propose a secure health data transmission protocol in remote healthcare monitoring system to protect patient's health information and prevent privacy from eavesdropping on the network. To achieve our security goals, we design an efficient secure protocol based on the identity-based cryptography with key evolution technique, and then confirm the superiority and the efficiency of the proposed protocol as compared with the existing protocol of Yang et al.
