Background Prosthetic hands with a myoelectric interface have recently received interest within the broader category of hand prostheses, but their high cost is a major barrier to use. Modern three-dimensional (3D) printing technology has enabled more widespread development and cost-effectiveness in the field of prostheses. The objective of the present study was to evaluate the clinical impact of a low-cost 3D-printed myoelectric-interface prosthetic hand on patients' daily life. Methods A prospective review of all upper-arm transradial amputation amputees who used 3D-printed myoelectric interface prostheses (Mark V) between January 2016 and August 2017 was conducted. The functional outcomes of prosthesis usage over a 3-month follow-up period were measured using a validated method (Orthotics Prosthetics User Survey-Upper Extremity Functional Status [OPUS-UEFS]). In addition, the correlation between the length of the amputated radius and changes in OPUS-UEFS scores was analyzed. Results Ten patients were included in the study. After use of the 3D-printed myoelectric single electromyography channel prosthesis for 3 months, the average OPUS-UEFS score significantly increased from 45.50 to 60.10. The Spearman correlation coefficient (r) of the correlation between radius length and OPUS-UEFS at the 3rd month of prosthetic use was 0.815. Conclusions This low-cost 3D-printed myoelectric-interface prosthetic hand with a single reliable myoelectrical signal shows the potential to positively impact amputees' quality of life through daily usage. The emergence of a low-cost 3D-printed myoelectric prosthesis could lead to new market trends, with such a device gaining popularity via reduced production costs and increased market demand.

Purpose: The purpose of this study was to develop a resilience enhancement program applying mindfulness meditation (REP-MM) and evaluate the effects of the program on post-traumatic stress (PTS), resilience, and health-related quality of life (HRQoL) in patients with ileostomy. Methods: The REP-MM was developed by combining the resilience enhancement program with mindfulness meditation according to four patterns. The program was developed through identifying patients' needs, reviewing relevant literature, developing a preliminary program, and testing content validity and user evaluation. The participants were 55 patients with ileostomy. We conveniently assigned 27 patients to the experimental group and 28 to the control group. The study was conducted in conducted in a hospital from January 22 to May 30, 2019. The REPMM was provided to the experimental group, and conventional ileostomy care was provided to the control group using a nonequivalent control-group pretest-posttest design. Results: ANCOVA revealed that the levels of PTS (F = 321.64, p < .001), resilience (F = 111.86, p < .001), and HRQoL (F = 31.08, p < .001) in the experimental group were higher than those in the control group when comparing pretest to posttest changes. Conclusion: The REP-MM is effective in PTS, resilience, and HRQoL in patients suffering from post-stoma creation crisis. The REP-MM can induce positive self-recognition changes in patients with ileostomy through dispositional, situational, relational, and philosophical interventions. We suggest nurses reduce PTS and improve resilience and HRQoL in patients with ileostomy.

Wireless sensor networks consist of small battery powered devices with limited energy resources. Once deployed, the small sensor nodes are usually inaccessible to the user, and thus replacement of the energy source is not feasible. Hence, energy efficiency is a key design issue that needs to be enhanced in order to improve the life span of the network. In BCDCP, all sensors send data from CH (Cluster Head) and then to BS (Base Station). BCDCP works well in small-scale network but in large scale network it is not appropriated since it uses much energy for long distance wireless communication. We propose a routing protocol - Triangular Clustering Routing Protocol (TCRP) - to prolong network life time through the balanced energy consumption. TCRP selects cluster head of triangular shape. The sensor field is divided into energy level and in every level we choose one node as a gate node. This gate node collects data and sends it to the leader node. Finally the leader node sends the aggregated data to the BS. We show TCRP outperforms BCDCP with several experiments.

Korea's housing structure is predicted that one-person housing will be the most common type of housing in Korea. Therefore, this study intends to derive contents for designing a one-person housing space considering the life of a rapidly increasing one-person householder. For this purpose, this study objectively derives the social, economic and cultural influencing factors of one-person households through big data analysis, and analyzed the correlation between contents using social network analysis methodology. In this paper, 60 core contents related to one person housing space were derived by applying big data analysis methodology. And through social network analysis, the most influential contents were derived from the space editing and space composition categories. This means that the residential space is an important part of the design idea that can flexibly respond to changes in the user's life. Based on this study, future research will focus on the concept and design methodology of one-person housing space.
