The masticatory muscle relaxation appliance is developed to improve the malhabit of tooth clenching of the wearer. The repeated clenching of the tooth causes excessive attrition of tooth set. The intraoral appliance measures the tooth clenching pressure data and transmits the data to masticatory muscle relaxation appliance. The appliance compares the pressure data with the reference value and generates the warning signal. The relaxation appliance also stores the clenching pressure data for clenching habit analysis. The appliance is designed with a microprocessor, real time clock, nonvolatile read write memory and dual serial communication ports.

Non-volatile memory (NVM) supports both byte addressability and non-volatility. These characteristics make it feasible for NVM to be employed at any layer of the memory hierarchy such as cache, memory and disk. An interesting characteristic of NVM is that, even though it supports non-volatility, its retention capability is limited. Furthermore NVM has tradeoff between its retention capability and write latency. In this paper, we propose a novel NVM-based file cache management scheme that makes use of the limited retention capability to improve the cache performance. Experimental results with real-workloads show that our scheme can reduce access latency by up to 31% (24.4% average) compared with the conventional LRU based cache management scheme.

This study aims to explore the effects of poetry therapy program on individual stress, depression, and self-esteem for rural residents. For the research data, before the end of the poetry therapy program, participants were asked to write a confession, and as a retrospective study, in-depth interviews were conducted with 4 participants to find out whether the effects of the program continued after about 14 months. According to the results of the study, after the program ended, it was said that it was a meaningful time to communicate and live positively through poetry. In a retrospective study, it was said that poetry writing relieved depression, released and purified emotions, created a sense of relaxation and provided an opportunity for self-reflection. Based on these results, it was confirmed that rural residents who are experiencing many psychological difficulties can improve their negative psychology and find peace of mind through poetry writing.
