As the usage of computer based systems continues to increase in our normal life, there are constant efforts to enhance the accessibility of information for handicapped people. For this, it is essential to develop new interface ways for physical disabled peoples by means of human-computer interface (HCI) or human-machine interface (HMI). In this paper, we developed HMI using electromyogram (EMG) and electrooculogram (EOG) for people with physical disabilities. Developed system is composed of two modules, hardware module for signal sensing and software module for feature extraction and pattern classification. To maximize ease of use, only two skin contact electrodes are attached on both ends of brow, and EOG and EMG are measured simultaneously through these two electrodes. From measured signal, nine kinds of command patterns are extracted and defined using signal processing and pattern classification method. Through Java based real-time monitoring program, developed system showed 92.52% of command recognition rate. In addition, to show the capability of the developed system on real applications, five different types of commands are used to control ER1 robot. The results show that developed system can be applied to disabled person with quadriplegia as a novel interface way.

Purpose: This descriptive research was carried out to identify how high school students' attitude to death and their meaning of life were affected by hospice volunteering and death education. Methods: This study is based on a structured questionnaire designed for 180 high school students who were given death education while doing volunteer work at non-profit hospice hospitals and another 288 high school students not doing any hospice volunteer work. The collected data was processed by the SPSS 20.0 program and then analyzed by $x^2$ test, t-test and ANOVA test. Results: High school students' attitude to death and their meaning of life showed significant differences depending on whether or not they had volunteered at hospice hospitals. The group with hospice volunteering experience tended to be more negative about death and have a higher meaning of life compared to those without hospice volunteering experience. Students with proper hospice recognition made up 52.4%, those who expressed hopes to receive hospice-care themselves if necessary accounted for 70.5%, and those who said they would like to take care of their family members either at home or at a hospice center if any of them got incurably sick comprised 59.0%. Those who thought dignified death is to be with one's family or any other meaningful person were 47.6% and 18.5% of the students thought that 'thinking they had led a meaningful life' was the core of a dignified death. Conclusion: Given the above results, it became clear that hospice volunteering and death education can affect high school students' meaning of life and their attitudes toward death.

Objectives : The purpose of this case-control research was to investigate the effects of acupuncture stimulation on autonomic nervous system for patients with HRV and to find out relationship with anti-stress effects. Methods : The study group consists of 24 patients with self-recognition of stress as the case group, and 20 normal person as the control group by similar age. We measured HRV of case and control groups before acupuncture stimulation, prick acupuncture in Hegu(LI4), Taichong(Liv3), Shenme(H7), Neiguan(P6), Zusanli(S36). After treating for 20 minutes, measurement values of HRV and PSV were compared for pre-acupuncture and post-acupuncture. Results : 1. LF norm, HF norm, LF/HF between the case and control groups were significant different in HRV before acupuncture stimulation in the 1st experiment. 2. HRT, SDNN, SDSD, LF norm, HF norm, and LF/HF of the case group were significant different in HRV after acupuncture stimulation in the 1st experiment. HRT of the case group was significantly different in HRV after acupuncture stimulation in the 1st experiment. 3. LF norm, HF norm, LF/HF of the case group were significant different between the 1st and 2nd experiment in HRV before acupuncture stimulation. 4. LF norm, HF norm, and LF/HF were significant different between the 1st and 2nd experiment in HRV of patients whose symptoms improved. But HRV of patients whose symptoms unimproved didn't show significant difference. Conclusion : The results suggest that acupuncture stimulation is associated with changed activity in the sympathetic and parasympathetic nervous system. Measurement values of HRV is suitable to estimate the activity of automatic nervous system.
