This study is aimed to introduce the newly developed mobile application for effective provision of assistive devices for people with disabilities in South Korea. By combining of ICF code and ISO 9999 code, more effective way of searching user fit assistive device information and selecting appropriate assistive devices were possible. 10 people with visual impairment were recruited for an usability testing. For the data analysis, paired t-test were used and confidence interval was 95%. The result showed newly developed mobile application was more effective in comparison with on-line based assistive device information. The outcome of this study will enhance the provision of assistive devices for people with disabilities more effectively within better user understanding of their needs and compensate for their body function as well as environmental barriers.

Currently, studies to predict the risk of rectal cancer surgery select MRI image slices based on the clinical experience of surgeons. The purpose of this study is to semi-automatically select and classify 2D MRI image slides to predict the risk of rectal cancer surgery using biomarkers. The data used were retrospectively collected MRI imaging data of 50 patients who underwent laparoscopic surgery for rectal cancer at Gachon University Gil Medical Center. Expert-selected MRI image slices and non-selected slices were screened and radiomics was used to extract a total of 102 features. A total of 16 approaches were used, combining 4 classifiers and 4 feature selection methods. The combination of Random Forest and Ridge performed with a sensitivity of 0.83, a specificity of 0.88, an accuracy of 0.85, and an AUC of 0.89±0.09. Differences between expert-selected MRI image slices and non-selected slices were analyzed by extracting the top five significant features. Selected quantitative features help expedite decision making and improve efficiency in studies to predict risk of rectal cancer surgery.

In this paper, we analyzed the latest research trends, challenges, and potential applications of next-generation solar cell materials in various industrial fields. In addition, future prospects and possibilities of Smart Textile Hybrid Energy Harvesting Devices that will supply electricity by combining with wearable IoT devices are presented. The hybrid textile energy harvesting device fused next-generation solar cells with tribo-piezoelectric devices will develop into new 'Convergence Integrated Smart Wear' by combining the material itself with wearable IoT devices in the era of the 4th industrial revolution. The next-generation nanotechnology and devices proposed in this paper will be applied to the field of smart textile with an energy harvesting function. And we hope it will be a paradigm shift that evolves into creative products which provide AI services such as medical & healthcare by convergence with the future smart wear industry.

Inernet of Things(IoT) is interaction with each other, collecting, sharing, and analysing the data. IoT has been noted in combining the fields of medical service in particular. However, the security issue is caused, while IoT is receiving attention. U-Health and medical devices, which deal mainly the personal health information, is required to a high level of privacy and security of health information. This study analyzes cases of leakage of personal medical information, security of IoT, privacy flow, and the response strategies.

Used medical equipment utilized in medical technology, most are not human or environmental risks likely to in normal medical technology. Therefore, the risk is close to zero so that medical devices are classified into Class 1 medical device, such as little or no risk by treating. It can be minimized without arising unnecessary and waste of time. As handlers in the medical device vendors are expanding the area of the business, we can uplift operators' commitment to the business and for the people's choice. In this paper, our research are presented to improve the legal and regulatory directions for the distribution of used medical devicesin in order to establish and promote a fair deal of diversity.

This paper proposes the U-healtcare middleware that is based on mininumCORBA. Ubiquitous healthcare system is generated by combining the technologies of computer system and medical system. This makes available that the person can receive medical treatment anywhere, anytime at on-line. The Healthcare devices are connected to network system as wire or wireless internet. So, the computer system can gather the vital information from the person at the real time and transfers the information to the server system that processes the medical information. When a medical doctor makes a diagnosis they can get more information about the patient by using the information within the server. Users would like to receive more services in the ubiquitous healthcare system than the traditional medical system. And in U-healthcare system, every healthcare devices and the users have to be connected to network system and the information from them has to be integrated. U-Home Healthcare middleware I proposed in this paper will do everything that I mentioned above.

Internet of Things(IoT) using a variety of technologies in combination provides a convenient, elevated range of services to users. IoT has been noted in combining the fields of medical service in particular. However, with the advent and growing of IoT, the more medical services are evolving, security problems caused by leakage of personal health information will become more serious. U-Health and medical devices, which deal mainly the personal health information, is required to a high level of privacy and security of health information. Therefore, the introduction of the IoT in the healthcare industry requires the medical information security as a prerequisite. This study analyzes security status and trend of IoT, personal medical information leakage cases, the health information protection measures in accordance with the life cycle of medical information, and the standardized protection technologies.
