As our society is rapidly entering an aging society, interest in mobile health care services for disease prevention and health care for the elderly is increasing. To increase the usability of mobile healthcare services, UI design should be considered from an older person's perspective and a specific evaluation system is required to diagnose these UI usability levels. This study aimed to develop a UI usability evaluation area of mobile-healthcare application for the elderly. For this, we conducted a literature analysis to explore the comprehensive UI usability evaluation factors, and FGI for expert groups and user groups to derive UI usability evaluation areas and detailed evaluation factors. As a result, the usability evaluation areas for the elderly were divided into four areas 'design', 'contents', 'process', and 'system'. A total of 13 sub-factors and 32 detailed constructions have been derived.

As IoT technology has gained the attention all around the world, the development for various services of healthcare, smart city, agriculture, and defense based on IoT is in progress. However, it is likely that healthcare services based on IoT have a problem of being leaked of patients' biological information by a third party and that risks patients' lives. In this paper, an IoT health care service managing model based on location sensor is proposed, which secures the biological information of a patient and simplifies the procedure to process the treatment and administration steps by using the data resources sensed. Even when an emergency occurs, this proposed model can respond quickly using the location information of the patient, which enables the staff in the hospital to locate the patient in real time. In addition, there is an advantage to minimize the time and the process of care, because the location of the equipment for necessary treatment is possible to be instantaneously located with attached sensors.

The purpose of this study was to confirm the complex relationship between patient safety-medical quality and hospital management activities to observe the mediating effect of organizational culture in the relationship due to healthcare accreditation adoption. For this, we conducted a 4 weeks survey, from September 22, 2014 to October 17, 2014 to the employees of 6 hospitals that could accommodate less than 300 patients or more than 300 patients located in Daegu and Gyeongbuk. The study includes 377 participants who have worked for more than one year in the hospital. All of hospital with less than 300-beds or more than 300-beds, such as patient safety-medical quality, organizational culture, hospital management activities found a positive correlation among variables. The mediating effect of organizational culture in the relationship between patient safety-medical quality and hospital management activities was shown by the partial mediating effect and high causal effect. Therefore, these study suggest that patient safety-medical quality due to healthcare accreditation adoption has the potential to improve hospital management activities.

The purpose of this study is to provide basic data for developing future ethics education programs by surveying healthcare providers working at institutions of various sizes, using Ethical Issues in Clinical Practice tool. Data were collected from 149 healthcare providers working at medical institutions in G-do. Analysis was done using t-test, ANOVA, Pearson correlation coefficient, and Multiple regression with IBM SPSS WIN/21.0. Needs for ethics education was inversely correlated to end-of-life treatment issues (r=-.22, p=.007) and patient care issues (r=-.28, p<.001). The most influential factor on the subjects' needs for ethics education was patient care issues (β=-.246, p=.035), followed by Buddhism (β=.208, p=.010). The explanatory power was 13.4% (F=5.596, p<.001). Therefore, when organizing the contents of ethics education program, patient care issues should be included to meet the needs of the subjects. Also, a customized program regarding the subjects' religion is necessary.

The rapid development of healthcare information management for 3D medical digital library, 3D PACS and 3D medical diagnosis has addressed security issues with medical IT technology. This paper presents multiple 3D medical image data for protection, authentication, indexing and diagnosis information hiding applied to healthcare information management. The proposed scheme based on POCS watermarking embeds the robust watermark for doctor's digital signature and information retrieval indexing key to the distribution of vertex curvedness and embeds the fragile watermark for diagnosis information and authentication reference message to the distance difference of vertex. The multiple embedding process designs three convex sets for robustness, fragileness and invisibility and projects 3D medical image data onto three convex sets alternatively and iteratively. Experimental results confirmed that the proposed scheme has the robustness and fragileness to various 3D geometric and mesh modifiers at once.
