Purpose: The purpose of this study was to develop a Health Mileage Program (EHMP) to promote exercise amongst the elderly and assess the feasibility of the program. Methods: A literature review to identify the effects of exercise in the elderly was conducted. Relevant cases were investigated and in-depth interviews with exercise instructors were conducted, after which the EHMP was developed based on the assessment and tested in three regions. The outcome was evaluated using indicators such as attendance rate, number of participants, proportion of participants who received health education, and proportion of participants who measured their physical and mental status. Results: Based on assessment, we developed an EHMP composed of four steps. Following application of the EHMP in three regions, ${\geq}80%$ of the participants received incentives. Additionally, ${\geq}85%$ of participants underwent measurement of their physical and mental status. The proportion of participants who received health education differed among regions. Conclusion: The EHMP program increased participation and interest in exercise programs for the elderly. However, there is concern regarding availability due to regional differences in resources related to elderly exercise; therefore, it will be necessary to invest in infrastructure, including facilities, and knowledgeable instructors.

In wireless mesh network, studies on routing protocols have been actively carried out recently, and hop count is used as a major routing metric in destination-sequenced distance-vector (DSDV) routing protocol, which is a representative proactive routing protocol. Although hop-by-hop multi-path (HMP) DSDV and enhanced HMP (EHMP) DSDV routing protocols perform routing by considering both hop count and residual bandwidth within one hop distance nodes, it has a shortcoming that routing is carried out via non-optimal path from the aspect of end-to-end routing. In order to overcome the shortcoming, a cost-aware multi-path (CAMP) DSDV routing protocol is proposed in this paper, which considers hop count and end-to-end minimum residual bandwidth. Simulation results based on NS-2 show that the proposed routing protocol performs better than DSDV, HMP DSDV, and EHMP DSDV protocols from the aspect of throughput and packet delivery ratio, by appropriately using hop count and end-to-end minimum residual bandwidth information and has the same number of management messages with HMP DSDV and EHMP DSDV protocols.

One of the most famous proactive routing protocols, DSDV (Destination -Sequenced Distance-Vector), is based on the minimum hop count. This paper suggests BIMP(Bypass Information Multi-Path) DSDV routing protocol that this protocol could route reliably as it can take the information of the bypass for the solution of the problem on EHMP DSDV. In this paper, the protocol checks throughput, packet delivery delay, packet delivery ratio, number of management messages, packet transmit finish time, etc on the traffic compared to DSDV, HMP DSDV, and EHMP DSDV protocols.

Technological advancements taken the health care industry by a storm by embedding sensors in human body to measure their vitals. These smart solutions provide better and flexible health care to patients, and also easy monitoring for the medical practitioners. However, these innovative solutions provide their own set of challenges. The major challenge faced by embedding sensors in body is the issue of lack of infinite energy source. This work presents a meta-heuristic based routing model using modified PSO, and adopts an energy harvesting scheme to improve the network lifetime. The routing process is governed by modifying the fitness function of PSO to include charge, temperature and other vital factors required for node selection. A reactive routing model is adopted to ensure reliable packet delivery. Experiments have been performed and comparisons indicate that the proposed Energy Harvesting and Modified PSO (EHMP) model demonstrates low overhead, higher network lifetime and better network stability.
