  • In this paper, we analyzed the effects of musical stimuli on humans in performing mathematical tasks through EEG measurements. The musical stimuli were divided into preferred music and non-preferred music, and mathematical tasks were divided into memorization task and procedure task. The data measured in the EEG experiments was divided into frequency bands of Theta, SMR, and Mid-beta because of the concentration. In our results, preferred music causes more positive emotional response than no music and non-preferred music regardless of the type of mathematical task.

  • Objectives: The purpose of this study is to examine the relationship between sexually explicit video viewing and social support through the mass media and the sex openness of adolescents. Methods: This study used as the main data of 'Study on Measures against Sexualization of Juveniles through Mass Media in the Smart Age' conducted by 'National Youth Policy Institute' in 2014 nationwide. 3,176 of the 4,356 adolescents in Korea were selected as the final study subjects after excluding the 1,180 missing adjectives. Results: As a result, sex openness of male students was higher than that of female students. The higher the grade, the higher the sex openness, and the higher the stimulus, the higher the sex openness. The higher the imitation sharing, the higher the sex openness. The higher the human rights violation, the lower sex openness. Finally, the higher the social support, the higher the sex openness. Conclusions: In conclusion, strengthening the management of realistic media providers and emotional education rather than the unconditional regulation of mass media is expected to help prevent adverse effects on the sex openness of adolescents.

  • As Christine Daley suggested, "interaction-image" is considered to be typical in the age of "Cinema 3.0", which integrates the interactivity of game art and obscures the boundary between producers and customers. In this case, users are allowed to involve actively in the scene as "players" to manage the tempo of the story to some extent, it, thus, makes users pleased to watch interactive movies repeatedly for trying a diverse option to unlock more branch lines. Accordingly, this paper aims to analyze the contributory factors and effect mechanism of users' reuse intention for gamified interactive movies and offer specific concepts to improve the reuse intention from the interactive film production and operation perspectives. Upon integrating the Flow theory and Technology Acceptance Model (TAM) and separating the intrinsic and extrinsic motivations of key factors based on Stimulus-Organism-Response (S-O-R), the research builds an empirical analysis model for users' reuse intention with cognition, design, attitude emotional experience and conducts an empirical analysis on 425 pieces of valid sample data applying SPSS22 and Amos23. The results show that user satisfaction and flow experience impact users' reuse intention highly and perceived usefulness, perceived ease of use, perceived enjoyment, remote perception, interactivity, and flow experience have significant positive influence on user satisfaction experience.

  • The purpose of this study is to determine the differences in eye-tracking, which is one of the emotional reactions of the autonomic nervous system, against various experimental stimuli that vary in terms of the movement attributes of graphic image. This experiment conducted an analysis of variance of the movement factors(n) in each movement attribute(speed, horizontality movement, verticality movement, diagonal movement). Dependent variables were the fixation starting time, the fixation dwell time, the whole fixation time from stimulus appearance, and the eye-tracking length. The result of eye-tracking against movement speed showed nonsignificant differences for each movement attribute. In the horizontality movement, the → movement was higher than the ← movement. In the verticality movement, the ↑ movement was higher than the ↓ movement. In the diagonal movement, there was not significant differences for each movement attributes.

  • The purpose of this study was to verify human physiological responses to emotional lighting system using LED (light emitting diode) flat lighting. Subjects were ten males in their twenties without medical history to eyes. Colors of LED lighting are red, orange, yellow, green, blue, purple and colorless (white). They were stimulated by LED lighting for 5 minutes. We measured body temperature, heart rate variability (HRV) and electroencephalogram (EEG) before and after color stimulus. In case of EEG analysis, relative power ${\alpha}$ wave ratio decreased in the groups of colorless, red and orange color light. Also, sympathetic nerve was more activated than parasympathetic nerve and the body temperature was increased in the groups of colorless, red, orange, yellow color light. On the other hand, relative power ${\alpha}$ wave ratio increased and parasympathetic nerve was more activated than sympathetic nerve and the body temperature was decreased in the groups of green, blue and purple color light. The results imply that the LED color lighting system in the realistic experiment environment. In the future, studies with compounded both colors and modes according to situation or auditory as nature sound or olfactory as aroma will be required.

  • This study used intersubject representational similarity analysis (IS-RSA) to identify participant-response consistency patterns in previously published data. Additionally, analysis of variance (ANOVA) was utilized to detect any variations in the conditions of each experiment. In each experiment, a combination of ASMR stimulation, visual and auditory stimuli, and time-series emotional video stimulation was employed, and emotional ratings and physiological measurements were collected in accordance with the respective experimental conditions. Every pair of participants' measurements for each stimulus in each experiment was correlated using Pearson correlation coefficient as part of the IS-RSA. The results of study revealed a consistent response pattern among participants exposed to ASMR, visual, and auditory stimuli, in contrast to those exposed to time-series emotional video stimulation. Notably, the ASMR experiment demonstrated a high level of response consistency among participants in positive conditions. Furthermore, both auditory and visual experiments exhibited remarkable consistency in participants' responses, especially when subjected to high arousal levels and visual stimulation. The findings of this study confirm that IS-RSA serves as a valuable tool for summarizing and presenting multidimensional data information. Within the scope of this study, IS-RSA emerged as a reliable method for analyzing multidimensional data, effectively capturing and presenting comprehensive information pertaining to the participants.

  • This study was conducted to investigate whether Stroop-related cognitive task will be affected according to the preceding affective valence factored by matchedness in response time(RT) and whether facial recognition will be indexed by specific event-related potentials(ERPs) signature in normal person as in patients suffering from affective disorder. ERPs primed by subliminal(30ms) facial stimuli were recorded when presented with four pairs of affect(positive or negative) and cognitive task(matched or mismatched) to get ERP effects(N2 and P300) in terms of its amplitude and peak latency variations. Behavioral response analysis based on RTs confirmed that subliminal affective stimuli primed the target processing in all affective condition except for the neutral stimulus. Additional results for the ERPs performed in the negative affect with mismatched condition reached significance of emotional-face specificity named N2 showing more amplitude and delayed peak latency compared to the positive counterpart. Furthermore the condition shows more positive amplitude and earlier peak latency of P300 effect denoting cognitive closure than the corresponding positive affect condition. These results are suggested to reflect that negative affect stimulus in subliminal level is automatically inhibited such that this effect had influence on accelerating detection of the affect and facilitating response allowing adequate reallocation of attentional resources. The functional and cognitive significance with these findings was implied in terms of subliminal effect and affect-related recognition modulating the cognitive tasks.

  • Objectives: The purpose of this study was to find out the fear of dentist care, subjective recognition of dental health, and quality of life in the male high school students and to analyze the influencing factors on dental health care. Methods: A self-reported questionnaire was filled out by 243 special high-school in Deagu province from March 3 to March 14, 2014. The questionnaire consisted of general characteristics of the subjects(5 questions), subjective recognition of health and activities to improve health(6 questions), dental fear(20 questions), oral health related quality of life(16 questions). The instrument for dental fear was adapted from measured by Berggren Dental Fear Survey(DFS). A total of 20 DFS questions included treatment avoidance(8 questions), stimulus reaction(6 questions), and physiological reaction(5 questions) and score by Likert 5 scale. Cronbach alpha was 0.974 in the study. Oral health related quality of life was measured by 16 questions of CPQ11-14 for the adolescents by Lau. CPQ11-14 consisted of oral symptoms(4 questions), functional restriction(4 questions), and emotional wellbeing(4 questions). The instrument was score by Likert 5 scale and Cronbach alpha was 0.9354 in the study. Data were analyzed using SPSS 18.0 program for ANOVA and multiple regression analysis. Results: Fear of dentist care showed significant differences in treatment avoidance factor(p<0.001), stimulus reaction factor (p<0.05), and physiological reaction factor(p<0.001). The factors depended on subjective recognition of health and health-improving activities and differences in treatment avoidance factor(p<0.05) and physiological reaction factor(p<0.01). The dental symptoms factors showed significant differences in health recognition(p<0.001), interest in health(p<0.001), alcohol drinking status(p<0.001) and regular meal(p<0.001). While function limit factors showed differences in health recognition (p<0.001), interest in health(p<0.001), smoking(p<0.001), alcohol drinking(p<0.001) and regular meal(p<0.001). Mental and social stabilities factors showed significant differences in health recognition(p<0.001), interest in health(p<0.001) and alcohol drinking status(p<0.001). Among the factors influencing on the quality of life in dental health, interest in health(p<0.005), alcohol drinking(p<0.005) and physiological reaction in the midst of fear of dentist care(p<0.001) were the significant impact factor. Conclusions: It is necessary to develop a continuous and systematical program of dental health and dental care by experts so that the students can reduce the fear of dentist care by regular dental checkup and preventive treatment and care.
