Panfacial fracture is extremely difficult to manage facial injuries but concomitant injuries and severe complications including facial esthetic and functional problems can make it harder. Thorough evaluation and closed co-work with other specialists is needed when reduction and fixation cannot be achieved quickly. Emergency bony support and soft tissue key suture provide the patients with airway integrity, hard and soft tissue vitality. A systemic treatment plan must be made by 3D CT image. This plan include airway management for surgery, sequence of reduction and fixation, approach method, soft tissue resuspension and reconstruction of lost tissue like inferior orbital wall, zygomaic buttress and soft tissue. From known to unknown structures, accurate reduction and fixation will provide proper occlusion, facial projection, width, hight and function. Consideration about facial retaining ligaments must be given to prevent soft tissue sagging.

Personal Health Records(PHR) service offers patients a convenient and easy-to-use solution for managing their personal health records, crucial medical files, and emergency contacts. In spite of the indispensable advantages, PHR service brings critical challenges that cannot be avoided from consumer side if the security of the data is concerned. The problem of user's privacy infringement and leaking user's sensitive medical information is increasing with the fusion of PHR technology and healthcare. In this paper, therefore, we analyze the various security aspects that are vulnerable to the PHR service and needed to be resolved. Moreover, we analyze the security requirements from the point of view of the PHR users and application service providers and provides the PHR security mechanism for addressing PHR security threats and satisfying PHR security requirements.

Despite the ubiquity of telephone, the medium has received far less scholarly attention than it should deserve. This study begin with the purpose of fair appraisement of telephone in Korean social communication. To accomplish this purpose, the gratification obtained from telephone, the appropriateness of it as interpersonal communication medium and communication network through telephone were studied. The related raw data were collected from on-line survey process, and statistically analyzed. The result showed sociability, information, transaction, entertainment, emergency, and reassurance are gratifications obtained from telephone use. Younger persons tend to have more positive attitude to mobile phone as interpersonal communication medium. Particularly when the seniors are interpersonal communication partner and impending task is advice or request, younger persons tend to perceive mobile phone more appropriate than the elder persons do. And mobile phone deepens 'communication endogamy' of our society, especially in the youth. Thus, it is plausible to predict that mobile phone will be more important in social communication of our society when the youth become the mainstream of our society.

As crime has actually increased in recent years, various mobile applications related to safety and emergency measure have received much attention. Therefore, IoT (Internet of Things) technologies, which connect various physical objects with Internet communication, have been also paid attention and then diverse safety services based on IoT technologies have been on the increase. However, existing mobile safety applications are simply based on location based service (LBS). Also, as they are independently operated without the help of another safety systems, they cannot efficiently cope with various safety situations. So, this paper proposes the efficient smart safety service architecture with both the risky situation detection using user location as well as various sensing information and the risk congruence measure using the streetlight infrastructure. Additionally, UDID (unique device identifier) is utilized for the secure communication with the control center.

Purpose: The aim of this study was to compare the toxicologic profiles and outcome of poisoned patients by comparing the data obtained through telephone counselling, each provided by emergency medical information center (1339) and emergency dispatch center (119). Methods: We analyzed the telephone-based poison exposure data before and after Seoul 1339 merged to 119. We compared the Seoul 1339 call response data in 2008 with Seoul and Busan 119 call response data between 2014 and 2016. We analyzed the changes in the trend and quality of data obtained, as well as the quality of service provided by each center before and after this reallocation, by comparing the data each obtained through telephone counselling. Results: The data was collected for a total of 2260 toxin exposure related calls made to Seoul 1339 in 2009, and 1657 calls to 119 in Seoul and Busan between 2014 and 2016. Significant difference was observed for age, sex, and reason for exposure to toxic substance between the two groups. Conclusion: After the integration of 1339 with 119, 119 focused on role of field dispatch and hospital transfer, lacking the consulting on drug poisoning. Moreover, data on exposure to toxic substances at the pre-hospital stage indicate that drug information and counseling are missing or unknown. In addition, first aid or follow-up instructions are not provided. Thus, systematic approach and management are required.
