  • The purpose of this study is to examine the effects of integrated art therapy on the self-esteem of children who experienced domestic violence. In order to find out whether there is an effect, we used the nonparametric statistic as a quantitative study to verify the difference of self-esteem. In qualitative research, I used the dynamic familyization, sentence completion test, program report, feedback journal, and observation log from researcher and assistant therapist so as to get the deep understanding of their inner world. This study conducted a trauma test for 49 children in grades 4-6 from one elementary school in a city of Jeollabukdo Province. As a result, there was a significant increase in total self-esteem including their social life. family life, and school life after the program was implemented. Also, integrated art therapy promoted general perception and specific perception of self, which affected total self - esteem, social self - esteem, family self - esteem, and school self-esteem. So, it improves the self-esteem of children who have experienced domestic violence, In order to improve peer relations and interpersonal relations, if integrated art therapy is carried out in schools or institutions in the future, it will be possible to reduce social cost and distance.

  • The purpose of this study was to investigate the effect of contact type textile electrode structure on heart activity signal acquisition for smart healthcare. In this study, we devised six contact type textile electrodes whose electrode size and configuration were manipulated for measuring heart activity signals using computerized embroidery. We detected heart activity signals using a modified lead II and by attaching each textile electrode to the chest band in four healthy male subjects in a standing static posture. We measured the signals four times repeatedly for all types of electrodes. The heart activity signals were sampled at 1 kHz using a BIOPAC ECG100, and the detected original signals were filtered through a band-pass filter. To compare the performance of heart activity signal acquisition among the different structures of the textile electrodes, we conducted a qualitative analysis using signal waveform and size as parameters. In addition, we performed a quantitative analysis by calculating signal power ratio (SPR) of the heart activity signals obtained through each electrode. We analyzed differences in the performance of heart activity signal acquisition of the six electrodes by performing difference and post-hoc tests using nonparametric statistic methods on the calculated SPR. The results showed a significant difference both in terms of qualitative and quantitative aspects of heart activity signals among the tested contact type textile electrodes. Regarding the configurations of the contact type textile electrodes, the three-dimensionally inflated electrode (3DIE) was found to obtain better quality signals than the flat electrode. However, regarding the electrode size, no significant difference was found in performance of heart signal acquisition for the three electrode sizes. These results suggest that the configuration method (flat/3DIE), which is one of the two requirements of a contact type textile electrode structure for heart activity signal acquisition, has a critical effect on the performance of heart activity signal acquisition for wearable healthcare. Based on the results of this study, we plan to develop a smart clothing technology that can monitor high-quality heart activity without time and space constraints by implementing a clothing platform integrated with the textile electrode and developing a performance improvement plan.
