  • This study examined the differences in the improvement of walking ability between treadmill training with fast-tempo auditory stimulation (FTAS group) and the general treadmill training (control group) in hemiplegia. The subjects were allocated randomly into both groups. Eleven patients of the FTAS group and 11 patients of the control group underwent training for 30 minutes per day for 6 weeks. Before and after intervention, the walking ability was measured by the 10m gait-evaluation and the number of steps in 20m walking. The gait velocity was improved further in the FTAS group than the control group (p<.05). This study provides evidence of the efficacy of treadmill training with FTAS in improving the gait ability when compared to the general methods in patients with chronic hemiplegia.

  • Time-varying tempo of a song is one of the error sources for the identification of a note duration in automatic music recognition. This paper proposes an improved music transcription scheme equipped with the identification of note duration considering the time-varying tempo. In the proposed scheme the measures are found at first and the tempo, the playing time of each measure, is then estimated. The tempo is then used for resizing each IOI(Inter Onset Interval) length and considered to identify the accurate note duration, which increases the degree of correspondence to the music piece. In the experiment the proposed scheme found the accurate measure position for 14 monophonic children songs out of 16 ones recorded by men and women. Also, it achieved about 89.4% and 84.8% of the degree of matching to the original music piece for identification of note duration and pitch, respectively.

  • The purpose of this study is to compare and analyze the effects of stepping-in-place tempo and roundhouse kick types on response time. Fifteen males participated in this experiment. All have over ten years of experience and hold a forth dan(degree) black belt in taekwondo. The task is when the participants are doing stepping in place they respond to the light stimulus as fast as they can do roundhouse kick. Five different stepping in place tempos (100, 120, 140, 160, and 180 bpm) and four different types of roundhouse kick(front leg body roundhouse kick, front leg head roundhouse kick, back leg body roundhouse kick, and back leg head roundhouse kick) were used. Three measurements were taken for each of the different combinations of conditions for a total of 60 measurements. For data analysis, two-way ANOVA with repeated measures was used and pair-wise comparisons were performed using bonferroni statistics. The results show that there was significant difference interaction effect between stepping in place tempo and roundhouse kick type in the response time. And, there were significant difference in main effect of response time in accordance with stepping in place tempo and roundhouse kick type. The response time of roundhouse kick was the fastest at 160 bpm of stepping in place tempo, but there was no significant difference between 140 and 160 bpm. Front leg body roundhouse kick was the fastest. And, the response time was the fastest when front leg body roundhouse kicked at 140 bpm of stepping in place tempo. Stepping in place tempo between 140 and 160 bpm is the most effective to optimize the response time. And, More effective response time was front leg roundhouse kick as compared with back leg roundhouse kick and, body roundhouse kick as compared with head roundhouse kick. The findings in this study will provide useful information for performance improvement and will help with strategy for taekwondo competition.

  • This study has researched that tempo is an element influencing the fun of narrative webtoon. In spite of many elements that could create fun in narrative webtoon, the theory this study pays attention to is the accumulation and solution of tension. Lee Hyun-bee said in his book that the accumulation and solution of tension would be the element creating fun. Tensions of a story create the immersion by bringing readers into the story. However, if such tensions are maintained throughout the whole story, readers get insensitive to tensions, so that the accumulation and solution of tension should be used in turn to maintain the immersion. One of the directions creating the accumulation and solution of tension in narrative webtoon is the direction of tempo. When creating a narrative webtoon with the full-length structure, it is not easy to describe the whole incident from beginning to the end of it in order of time. Therefore, it is inevitable to have differences between story time and narrative time, and the difference of this time is called 'tempo'. This tempo creates fun when readers are immersed in the work, by adjusting breaths of the story in the direction of narrative webtoon. Such a role of tempo direction is based on the relation between the occurrence of tempo direction and information of the story. The information actually leading the story creates the accumulation and relief of tension which is the essential element of fun formation while tempo also maximizes the effects of accumulation and relief of tension. Tempo direction in narrative webtoons uses panels and gaps between them. The scene direction using panels and gaps between them considers tempo and dynamics because of the temporality of panels and gaps between them. This paper analyzes the use of tempo direction for narrative webtoon through the analysis on the 1st episode of . The significance of this study is to reveal that tempo direction is one of the factors creating fun in narrative webtoons, and also to suggest the theoretical grounds for researches on direction creating fun in the future.

  • In this paper, we propose a method to extract and classify features of multi-channel ElectroEncephalo Graphy (EEG) that change according to various musical tempo stimuli. In the proposed method, a 3D convolutional bidirectional gated recurrent neural network extracts spatio-temporal and long time-dependent features from the 3D EEG input representation transformed through the preprocessing. The experimental results show that the proposed tempo stimuli classification method is superior to the existing method and the possibility of constructing a music-based brain-computer interface.

  • In , music becomes a passage of spaces in dreams and at the same time causes a problem of temporality between spaces with different time speeds. This paper aims to examine the temporality of the music through Bergson's concept of time. The music used in the film, 《Non, je ne regrette rien》, is divided into the original version, the slowed-down version, and the rearranged version with the slowed-down, and this study visually confirmed the characteristics and similarities through practical analysis. From the perspective of Bergson's perception and memory diagram, non-diegetic music of the actual(the rearranged version) in which diegetic music of the virtual(the slowed-down version) inherent, plays the role of film music and music signal simultaneously. Also, the original version and the slowed-down version are the relationship of durational identity with qualitative changes. We looked at the position in the inverted cone diagram and applied their relationship to the diagram. It is a great achievement of this study that we explored the temporality of music in the multi-layered structure of , based on Bergson's philosophy of coexisting with the present and the past.

  • In this paper, we propose a system that recommends music through tempo-oriented music classification and sensor-based human activity recognition. The proposed method indexes music files using tempo-oriented music classification and recommends suitable music according to the recognized user's activity. For accurate music classification, a dynamic classification based on a modulation spectrum and a sequence classification based on a Mel-spectrogram are used in combination. In addition, simple accelerometer and gyroscope sensor data of the smartphone are applied to deep spiking neural networks to improve activity recognition performance. Finally, music recommendation is performed through a mapping table considering the relationship between the recognized activity and the indexed music file. The experimental results show that the proposed system is suitable for use in any practical mobile device with a music player.
