We propose to design a Holochain-based security and privacy protection system for resource-constrained IoT healthcare systems. Through analysis and performance evaluation, the proposed system confirmed that these characteristics operate effectively in the IoT healthcare environment. The system proposed in this paper consists of four main layers aimed at secure collection, transmission, storage, and processing of important medical data in IoT healthcare environments. The first PERCEPTION layer consists of various IoT devices, such as wearable devices, sensors, and other medical devices. These devices collect patient health data and pass it on to the network layer. The second network connectivity layer assigns an IP address to the collected data and ensures that the data is transmitted reliably over the network. Transmission takes place via standardized protocols, which ensures data reliability and availability. The third distributed cloud layer is a distributed data storage based on Holochain that stores important medical information collected from resource-limited IoT devices. This layer manages data integrity and access control, and allows users to share data securely. Finally, the fourth application layer provides useful information and services to end users, patients and healthcare professionals. The structuring and presentation of data and interaction between applications are managed at this layer. This structure aims to provide security, privacy, and resource efficiency suitable for IoT healthcare systems, in contrast to traditional centralized or blockchain-based systems. We design and propose a Holochain-based security and privacy protection system through a better IoT healthcare system.

효과적인 스마트의류에 기반한 유-헬스케어 시스템 구축을 위해서는 스마트의류에 적합한 하드웨어 및 소프트웨어 모듈의 설계가 필요하다. 그리고 스마트의류에서 센싱된 생체신호를 서버로 전달하기 위해서는 센싱신호의 수집 및 처리를 위한 게이트웨이 스마트폰 프로그램이 필요하다. 이를 위해서는 게이트웨이 프로그램 모듈을 잘 설계하고 기술하여 나중에 구현시에 어려움이 없도록 하여야 한다. 또한 의료진이 스마트폰에서 보내지는 생체신호를 수시로 모니터링 하지 않더라도 이들 신호의 변화값이 규칙/사실에 기반한 전문가시스템 구축으로 자동으로 진단되어 사용자에게 알려준다면 아주 유용한 유-헬스케어 시스템이 되리라 본다. 따라서 본 논문에서는 이러한 기능들을 갖춘 스마트의류 기반의 유-헬스케어 시스템 하드웨어 및 소프트웨어 모듈의 설계 방법을 제시함으로써 본 설계 방법이 유-헬스케어 상용화 시스템 제작에 매우 유용하게 활용될 수 있음을 보여준다.

In the field of Human-Computer Interaction design, persuasive design has gradually been applied to the system development and design process, especially for mobile application design. However, most mobile applications have hitherto a very short using lifecycle. Especially, design features with long-term persuasive effectiveness remain to be further researched and developed. In this study, we focused on investigating and identifying the durative persuasive design characteristics through a data mining process and evaluating the durative effectiveness through a long-term observation process. Total five hundred healthcare-related mobile applications were selected from Apple iTunes Store and a mixed method was conducted to extract the most common persuasive design characteristics. Based on the results of extraction, a representative healthcare-related mobile application was selected as experimental subject. Total one hundred and twenty participants were observed during a six-months experiment and the monitoring data of app usage of all participants was collected once a week. According to the evaluation model for behavior change identification process, participants with habit formation features were proved to have a significant long-term perception level for ten persuasive design characteristics. Further interview research was performed to investigate the participant's long-term perceptions on those characteristics for the purpose of identifying the durative persuasions. The results indicated that a long-term durative effectiveness can be observed and healthcare-related apps designed with those characteristics could have durative effectiveness. This study may contribute to the improvement of future mobile application designs in user experience and durative persuasion, as well as bringing future benefits for both mobile application developers and users.

Preconstruction process in a lean project delivery system was studied in one large healthcare project working for a general contractor. Researchers joined a new lean delivery project for approximately six weeks and participated in preconstruction process including design coordination, management coordination, and target costing while concurrently interviewing other project participants and employees, recording activity in meetings, and otherwise observing the process. The preconstruction process in lean project delivery system, called integrated project design, showed many benefits such as brining expertise of downstream players (i.e., mechanical and electrical contractors) into the design phase. However, lack of leadership and lack of design-integrator blocked the successful application of a new concept of design process.

In contemporary times, there is an increasing demand for a dedicated healthcare environment, all over the world. The main motivation for this demand is the level of awareness manifested by the users and reflected on their expectations. Therefore new research strategies and design actions are investigated in order to answer to the users' needs and to provide objective design tools for the specialist. This study continues a series of previous developments of the Healthcare Environment Color Index that should be used for public facilities in Korea and abroad. The cross-cultural approach is a new opportunity for exchanging know-how and for testing and calibrating the perception of the users on the color index. The gathering of results was made based on the online survey provided in this phase in English version for the Romanian users. The survey was intended as an objective mean of research and an efficient way of disseminating information on the subject thus contributing to increasing the level of awareness of the users. A total of 86 Romanian and 89 Koreans with valid answers took part in the survey. Comparative visualizations of the results showed significant similarities concerning the patterns of color preferences but also cultural and emotional differences. As a result both categories of users proved to be aware of the relation between healthcare environment color and its effects on health. They also showed a common understanding on the potential of the color index. As a result the most appealing colors to be applied to the healthcare environment were the series G and B, and the most effective ones were proved to be the ranges of high lightness and low saturation but also the medium high lightness and medium saturation. Both the similarities and the differences of choice between Romanians and Koreans show that cultural and emotional differences of color recognition are important and that should be taken into consideration in design, in order to generate an inclusive and efficient healthcare environment.
