The noise of MRI shooting is 100dB loud and has an intensive psychological and physiological influences on the human body. ECG signals were measured by experimental methods, while wearing earplugs for 15 minutes in the stable state. Then the ECG signals were measured for 30 minutes while listening to about 100dB of sound in a MRI equipment. In this study, the heart rate variability of men and women was analyzed according to the MRI noise stress level through the frequency analysis. As the MRI noise level is about 100dB, HRV analysis resulted in an imbalance between the sympathetic and parasympathetic. During the period from the resting state up to 10 minutes, the maximum stress state was shown. This study will encourage MRI workers to take interests in hearing protection for the patient and to make objective indicators about MRI noises.

This convergence research was conducted to understand the effect of university students' addiction to smartphones on self-esteem and self-efficacy, with stress level and mental health as the parameters. The subjects were students from three universities located in J province, and 303 questionnaires were used as the data for analysis. The data were analyzed with Pearson's correlation, multiple regression and pathway analysis by SPSS and AMOS. As a result, addiction to smartphones showed negative (-) correlation with self-esteem, self-efficacy, and mental health, while showing positive (+) correlation with stress level. In addition, the addiction to smartphones has an influence on self-esteem and self-efficacy with stress level and mental health as the parameters. Therefore, in order to improve the self-esteem and self-efficacy of university students, programs should be developed to prevent and manage addiction to smartphones, relieve stress and promote mental health.

The relationship of stress and psychopathology with subjective or objective tinnitus intensity was investigated in 43 patients with tinnitus. Global assessment of recent stress scale, Beck depression inventory and symptom checklist-90-revision were used to measure stress perception and psychopathology. Subjective tinnitus intensity was assessed by subjective tinnitus severity inventory, whereas objective tinnitus intensity was assessed by tinnitogram. Scores of perceived stress related to interpersonal relationship and sickness or min had significantly positive correlation with subjective tinnitus intensity. In psychopathology, scores of somatization, interpersonal sensitivity, depression, anxiety, phobia, paranoid ideation, psychoticism had significantly positive correlation with subjective tinnitus intensity. However, stress perception and psychopathology did not significantly correlate with objective tinnitus intensity. These findings suggest that tinnitus may be associated with stress perception and multiple psychopathology including anxiety and depression. Thus, it is emphasized that Psychosocial intervention as well as effective consultation-liasion activity is needed for evaluation and treatment of patients with tinnitus.

Objectives : The purpose of this randomized, placebo-controlled, cross-over trial was to examine how acupuncture treatment at Shinmun(HT7) affects the brain activity and the autonomic nervous system(ANS), using electroencephalograms(EEG) and heart rate variability(HRV). Methods : Eighteen healthy volunteers participated in two separate experiments: in each experiment, either real acupuncture(RA) or non-penetrating sham acupuncture(SA) was applied at HT7 in random sequences to each person. The EEG and HRV measurements were conducted simultaneously before and during the acupuncture stimulation for 5 minutes, respectively. Resulting EEG and HRV parameters were compared between RA and SA groups. To assess differences according to the stress levels for participants, subgroup analysis was performed based on the results of the stress response index questionnaire. Results : In the results, acupuncture stimulation at HT7 increased ${\alpha}$ band in EEG. In the HRV analysis, heart rate was decreased significantly but HF and RMS-SD were increased in the RA group, compared with those of the SA group. In the subgroup analysis by stress level, participants in the RA group with high stress exhibited an increased in ${\alpha}$ band in their EEG while the low stress participants showed decrease or little increase in the band. For the SA group, ${\alpha}$ band reported relatively moderate changes in all channels. Conclusions : Our results showed that acupuncture induces changes in brain activation and the ANS. Acupuncture was related to the activation of the parasympathetic nervous system. The brain activities of the participants were different depending on the stress level.

Sleep quality among university students is important, especially for their physical and psychosocial wellbeing. This study was conducted to investigate the level of smartphone addiction and stress among university students, and to estimate the effects of those variables on sleep quality. Data were collected from August 1st to 14th, 2018 using an online self-report survey to measure demographics including daily activity and indulgence foods, smartphone addiction, perceived stress scale, and the Pittsburgh Sleep Quality Index (Korean version). Collected data were analyzed by independent t-tests, ANOVA, Pearson's correlation coefficients, and multiple regression. The results showed that smartphone addiction, stress, and sleep quality had positive correlation in each relation. Multiple regression analysis showed that the predictors of sleep quality were smartphone addiction (${\beta}=0.041$, p=.001) and stress level (${\beta}=0.177$, p=.001), and the regression equation explained 24.9% of sleep quality. Therefore, higher levels of smartphone addiction and stress were associated with lower sleep quality. Based on these results, it is necessary to reduce unnecessary use of smartphone usage, as well as to develop and apply programs for university students to improve their sleep quality.
