  • In this paper, we propose an EEG-based mental state prediction method during a mental tasks. In the experimental task, a subject goes through the process of responding to visual stimulus, understanding the given problem, controlling hand motions, and hitting a key. Considering the subject's varying brain activities, we model subjects' mental states with defining selection time. EEG signals from four subjects were recorded while they performed three mental tasks. Feature vectors defined by these representations were classified with a standard, feed-forward neural network trained via the error back-propagation algorithm. We expect that the proposed detection method can be a basic technology for brain-computer interface by combining with left/right hand movement or cognitive decision discrimination methods.

  • Purpose: The purpose of this study is to examine whether the level of participation in physical activity affects the mental health of adolescents, that is, their subjective well-being. In addition, we would like to see if adolescents can improve their satisfaction with life away from the negative emotions they are currently feeling through physical activities such as hand-help and consolation activities and check if self-esteem has mediating effects in this process. Design: Survey. Methods: The survey was conducted by the surveyor, with a total of 9,041. Results: First, it shows that the higher frequency of adolescents' physical activity leads to higher self-esteem and subjective well-being. Second, it shows that the higher the self-esteem leads to higher subjective well-being felt by adolescents. Third, the level of youth physical activity itself contributes to subjective well-being while also affecting self-esteem, and the self-esteem also affects the subjective well-being that adolescents perceive. Conclusion: It will be necessary to provide programs to enhance subjective well-being for students with poor school life adaptation and satisfaction with life, as well as continuous attention such as organization and counseling of programs in schools to enhance self-esteem. In addition, it is considered that by encouraging and guiding teenagers with low satisfaction with life and low self-esteem to physical activities such as volunteer activities and leisure activities that suit their aptitude, and the adolescents will get away from the negative emotions they are currently feeling and increase their satisfaction with adaptation to school life and life.

  • Purpose: The purposes of this study were to develop a drum club activities program for soldiers and to explore the effects of the program on the mental health of soldiers. Methods: This study used one group pretest-posttest design. A drum club activities program for soldiers was offered for 12 weeks with each session of 2 hours. A total of 33 participants were recruited but eighteen participants who did not participate in sessions of the program more than 3 times were dropped out of the study. Finally, data from 15 participants were analyzed using the SPSS 22.0 program. Mental health status (stress, anxiety and aggression) was measured by Vibraimage technology. Vibraimage technology is a useful and objective method to identify the human psychophysiological state by analyzing the movement of various frequencies and amplitudes of head motion and face image using camera. Results: There is statistically significant difference in anxiety (Z=-3.12, p<.001) after implementation of the program. However, there was no statistically significant difference in stress and aggression. Conclusion: The results indicate that the drum club activities program was effective in decreasing anxiety in soldiers. The drum club activities program can be considered as a possible nursing intervention strategy to reduce anxiety for soldiers.

  • The purpose of this study is to examine how the rural elderly assess the multi-dimensions of health. This includes the physical, mental and social dimensions of health, correlations among them, and whether there are gender differences and age-group (60's, 70's, 80 and over) differences. For this purpose, survey data was gathered from 881 rural elderly who live in a village. The statistical methods used for data analysis were descriptive statistics, t-test, ANOVA and correlations. The major findings of this study are as follows: Physical health was measured by self-rated health, ADL, IADL, and farmer symptoms. The respondents classified as 80 and over and female perceived their physical health more negatively. Mental health was perceived somewhat positively in general but female participants perceived their mental health more negatively than males. Social health of the rural elderly was relatively positive in comparison to the other dimensions of health. The rural elderly engaged in many social activities, and the majority of them had many social support networks composed of more than 12 persons. Relationships among the physical, mental and social health dimensions were different. The correlation of physical and mental health and the correlation of social and psychological health were statistically significant. However, the correlation of physical and social health had no significant meanings.

  • The Alcoholics Anonymous(AA) program has been known to be effective in many countries in helping alcoholics to stop drinking and to change their attitudes, beliefs, and behaviors. In this study, we examined AA activities among Korean AA members and measured the self-evaluated physical, social, and mental changes following the entry into the AA program. Out of identified 300 AA members who were attending 18 different AA group meetings at the time of the survey, 207 completed the self-administered questionnaire(response rate of 69.0%). T-test and ANOVA were used to compare the scores of physica(4-items), social(4-items), and menta(10-items) changes according to the level of AA activities. The proportion of the respondents who practiced the 11th step (meditation) or the 12th step (take alcoholics to a meeting after carrying messages) on the regular basis was 66.6% and 37.2%, respectively. The average time spent in meditation per week was $4.8{\pm}5.47$ hours. The length of participation in AA meetings has significantly positive impact on the average score of changes in all the 3 health states; physical(p<.01), social(p<.05), and mental states(p<.01). Also, practicing the 11th step was significantly associated with improvement of social(p<.01) and mental(p<.05), while practicing the 12th step improved only mental states(p<.01). Our findings demonstrated that not only the length of participation in AA meetings but also the practice of regular meditation(11th step) and taking alcoholics to an AA meeting after carrying messages(12th step) are very important for AA members, and lead to great positive changes in physical, social, and mental states following entry into the AA program.
