The usage of virtual reality (VR) in healthcare field has been gaining attention lately. The main use cases revolve around medical imaging and clinical skill training. Healthcare professionals have found great benefits in these cases when done in VR. While medical imaging on the desktop has lots of available software with various tools, VR versions are mostly stripped-down with only basic tools. One of the many tool groups significantly missing is annotation. In this paper, we survey the current situation of medical imaging software both on the desktop and in the VR environment. We will discuss general information on medical imaging and provide examples of both desktop and VR applications. We will also discuss the current status of annotation in VR, the problems that need to be overcome and possible solutions for them. The findings of this paper should help developers of future medical image annotation tools in choosing which problem they want to tackle and possible methods. The findings will be used to help in our future work of developing annotation tools.

As information and communications technology-based "smart hospitals" and "digital healthcare" have become a hot topic in the healthcare field, hospital mobile apps are gaining attention; but, the utilization rate is low due to lack of publicity, unstable systems, and late updates. In this situation, systematic research is needed to increase the utilization rate of hospital mobile apps, but related research has been rare. Therefore, this study integrates the information systems success model (ISSM) from the technical perspective and the expectation-confirmation model (ECM) from the cognitive perspective to demonstrate the influence mechanism on the continuous use intention of hospital mobile apps. For this purpose, an online survey was conducted among 181 Korean adults who have used hospital mobile apps. The results of the structual equation modeling showed that most of the quality factors have significant effects on expectation confirmation, perceived usefulness, and satisfaction. Additionally, expectation confirmation significantly affects perceived usefulness and satisfaction, and both perceived usefulness and satisfaction significantly affect the continuous use intention of hospital mobile apps. This study is of importance in that it integrates the ISSM and ECM and applies them to the context of using hospital mobile apps, which are underutilized in the healthcare field, and provides practical implications for increasing the utilization rate of hospital mobile apps and operating effective and efficient services through the findings.

Objectives : The purpose of this study was to propose the utilization plan of Ryodoraku in the U-health care systems. Methods : Computerized literature searches were performed for Ryodoraku related articles using the following databases: KISS, RISS, DBPIA, NDSL from 1990 to Oct 2010. Search terms were '양도락' or 'Ryodoraku' or 'U-health'. Due to Ryodoraku coming from Japan, additional literature review(articles published by 2008) on Japanese journal of Ryodoraku medicine was done for compensation. Results : 1. Introduction of U-health : As rapid progress of population aging and strong interest in health, the demand for the traditional Korean medical service is increasing. Until now healthcare service has provided post treatment by face-to-face manner. But according to related researches, proactive treatment is resulted to be more effective for preventing diseases. Particularly, the existing healthcare services have limitations in preventing and managing chronic geriatric degenrative diseases such as metabolic syndrome, CVA, coronary heart diseases, parkinson's diseases, degenerative joint disease, spondylosis, etc., because the cause of the above is complex and even related to life habit. As the advent of ubiquitous technology, patients with the chronic geriatric degenrative diseases can improve life habit such as poor eating habits and physical inactivity without the constraints of time and space through u-healthcare service. Therefor, lots of researches for u-healthcare service focus on providing the personalized healthcare service for preventing and managing that. To cope with this situations, The concept of u-healthcare service should be adopted in the traditional korean medicine and diagnostic devices suitable for it should be also devised and developed based on traditonal korean medine. 2. Review of existing Ryodoraku related articles for applying to U-health : articles investigating feasibility applying Ryodoraku to meridian diagnosis and raising problems of it, articles providing recent research trends of Ryodoraku, Ryodoraku related articles considering usefulness for U-health, and articles confirming the repeatability and reproducity of Ryodoraku were included. Based on the review of the above Ryodoraku related articles, several application of Ryodoraku in the U-health care system. Conclusions : To make preparations for the increasing need of traditional Korean medicine due to rising morbidity rate of chronic geriatric degenerative diseases, it is necessary to appropriately apply Ryodoraku to the U-health care system. The application of Ryodoraku is as follows. 1. To use Ryodoraku additionally to the established diagnostic device of metabolic syndrome, CVA, coronary heart diseases, parkinson's diseases, degenerative joint disease, spondylosis. 2. To apply Ryodoraku to the symptoms or diseases having a tendency to be diagnosed by correlation between the affected meridian and the lesion such as headache, nuchal pain, shoulder pain, low back pain, sciatica, HNP, etc. 3. To secure the repeatability and reproducity of Ryodoraku. 4. To devise and develop Ryodoraku appliance in order to overcome the known drawbacks and to improve error of measurement.

The Personal Information Protection Act, one of the revised 3 Data Laws, established a special cases concerning pseudonymous data. As a result, a personal information controller may process pseudonymized information without the consent of data subjects for statistical purposes, scientific research purposes, and archiving purposes in the public interest, etc. In addition, as a follow-up to the revised Personal Information Protection Act, a 'Guidelines for Utilization of Healthcare Data' was prepared, which deals with the pseudonymization in the medical sector. The guidelines are meaningful in that they provide practical criteria for accomplices by defining specific interpretations and examples that take into account the characteristics of healthcare data. However, the guidelines need to clarify the purpose of using pseudonymous data and strengthen the fairness of the composition of the data deliberation committee. The guidelines also require establishing a healthcare data compensation framework and strengthening the protection of rights for vulnerable subjects. In addition, the guidelines need to be adjusted for inconsistency with the Bioethics and Safety Act and the Medical Service Act. It is expected that this study will contribute to the creation of a safe environment for the utilization of healthcare data as well as the improvement of related laws and systems.

Smart healthcare systems, a convergent industry based on information and communications technologies (ICT), has emerged from personal health management to remote medical treatment as a distinguished industry. The smart healthcare environment provides technology to deliver vital information, such as pulse rate, body temperature, health status, and so on, from wearable devices to the hospital network where the physician is located. However, since it deals with the patient's personal medical information, there is a security issue for personal information management, and the system may be vulnerable to cyber-attacks in wireless networks. Therefore, this study focuses on a key-development and device-management system to generate keys in the smart environment to safely manage devices. The protocol is designed to provide safe communications with the generated key and to manage the devices, as well as the generated key. The security level is analyzed against attack methods that may occur in a healthcare environment, and it was compared with existing key methods and coding capabilities. In the performance evaluation, we analyze the security against attacks occurring in a smart healthcare environment, and the security and efficiency of the existing key encryption method, and we confirmed an improvement of about 15%, compared to the existing cipher systems.
