PURPOSE: The purpose of this study was to investigate the effect of action observational physical training with rhythmic auditory stimulation on muscle activity and gait ability in patients with stroke. METHODS: Twenty-six chronic stroke patients participated in this study were assigned into three groups, experimental group 1 (10% faster tempo rhythmic auditory stimulation with action observation training) n=8, experimental group 2 (average tempo rhythmic auditory stimulation with action observation training) n=9, and control group (action observation training) n=9. In this experiment, the corresponding exercise were applied into the subjects of three group for 30 minute a day, 3 time a week during 4 weeks. All participants were measured to muscle activity of lower limb, 10 meter walking test, Figure of 8 walk test, Dynamic gait Index. The collected data were analyzed by using SPSS (version 18.0 for window) and verified that each data was a normal distribution based on Shapiro-Wilk test. Between-group and within-group comparison was analyzed by using One-way ANOVA test, Paired t-test respectively. In all statistical analyses, significance level, ${\alpha}$ was set by .05. RESULTS: The above results revealed that the all experimental group 1 and experimental group 2 and control group were all effective to improve the lower limb muscle activities, gait ability. However more positive effects shown action observational physical training with rhythmic auditory stimulation experimental group. CONCLUSION: This study suggest that action observation physical training with rhythmic auditory stimulation is effective intervention for improvement of muscle activity and walking ability in chronic stroke patients.

Purpose: The purpose of this study was to identify whether inclined treadmill gait training with rhythmic auditory simulation (RAS) could improve on balance and gait in stroke patients. Method: Fifteen stroke patients who had agreed with the study were allocated to the group 1(n=5), group 2(n=5), or group 3(n=5). The group 1, group 2 and group 3 performed RAS with inclined treadmill gait training, inclined treadmill gait training and treadmill without incline gait training respectively for 3 weeks (30 minutes per session, 5 times in a week). The balance was assessed using Timed Up & Go (TUG) and Berg Balance Sale (BBS), and the gait was evaluated using 6 Minutes Walking Test (6MWT) and spatio-temporal walking variables as walking speed, cadence, Single Limb Support of affected side(SLS) and Symmetric Index(SI) before and after training. Result: Both the group 1 and group 2 showed significant improvement after training in all variables of balance and gait. The group 3 showed significant improvement in TUG values, 6MWT values, walking speed, cadence and SI. The changes in the group 1 were significantly greater in all dependent variables of balance and gait than those of the group 2 and group 3. The changes in the group 2 were significantly greater in TUG values, BBS scores, 6MWT values, walking speed, and cadence than those of the group 3. Conclusion: The result of this study show inclined treadmill gait training with RAS is more effective to improve balance and gait in stoke patients than inclined treadmill or general treadmill gait training without RAS.

The aim of this study was to investigate phoneme recognition in postlingually deafened adults with cochlear implantation. 21-cochlear implantee were participated. They was used cochlear implants more than 1 year. In order to measure consonant performance abilities, subjects were asked for 18 items of Korean consonants in a "aCa" condition with audition alone. The scores ranged from 11 to 86 ($60{\pm}17$)%. The consonant performance abilities correlated with implanted hearing threshold level, significantly (p<.046). This results suggest that consonant performance abilities of postlingual deafened adults cochlear implantee be important for implanted hearing. They had higher correct rates for fricatives and affricatives with distinctive frequency bands than for plosives, liquids & nasals with the same or adjacent frequency bands. All subjects had confusion patterns among the consonants of the same manner of articulation. The reason of consonant confusions was caused that they couldn't recognize different intensities and durations of consonants with the same or adjacent frequency bands.

We are exposed to the various external stimuli input from the environment, which cause emotional changes based on the characteristics of the stimuli. Unfortunately, there are no quantitative results on relationship between human sensibility and the characteristics of physiological signals. The objective of this study was to quantify EEG signals evoked by auditory stimulation based on the assumption that the analysis of the variability on the characteristics of the EEG waveform may provide the significant information regarding changes in psychological states of the subject. The experiment was devised with seven experimental conditions, which are control and six different types of auditory stimulation. Twenty subjects were used to obtain EEGs while introducing auditory stimulation. Wavelet transformation was employed to analyze the EEG signals. The results showed that the reconstructed signals at the decomposition level revealed the different energy value on the EEG signals. Also, general patterns of EEG signals in rest state compare with negative and positive stimulus were found. This study could be extended to estabilish an algorithm which distinguishes psychophysiological states of the subjects exposed to the auditory stimulation.

This study is to examine how a person's sense is changing in the process of gambling addiction and recovery. For this purpose, the ten of gambling abstinences were purposefully selected for intensive depth interviews. The data collected by thess interviews were analysed by Giorgi's(1970; 1985) phenomenological method. Meaningful units were categorized into 18 'emerging themes', and integrated by the total of 6 'essential themes' considering the interrelations of the emerging themes. Major findings of the study are as follows. Firstly, participants of this study lost their general senses in the addiction process by focusing on specific senses such as seeing and hearing. Secondly, participants have begun to regain the lost senses in the process of recovery, even though going through the 'pains of withdrawal'. Thirdly, the participants' experiences of recovery could be summarized as 'a recovery process of the general senses lost by gambling'. Based upon these findings, some suggestions for helping practice were proposed such as 'provision of informations about senses', 'program development of sense stimulation', and 'application of sense recovery training'.

PURPOSE: Examine the effects of auditory feedback and functional electrical stimulation on balance, walking ability, and lower extremity function of subacute stroke patients. METHODS: Twenty-seven subjects diagnosed with subacute stroke within six months were randomly divided into three groups: test group 1, which performed walking exercises with auditory feedback and functional electrical stimulation; test group 2, which performed walking exercises only with functional electrical stimulation; control group applied only functional electrical stimulation, with nine subjects each. RESULTS: There were significant pre- to post-intervention differences in BBS in the gait training group with auditory feedback and functional electrical stimulation treatment, and significant pre- to post-intervention differences in BBS, sit-to-stand time, and average step speed in the gait training group with functional electrical stimulation, but no statistically significant differences in between-group comparisons. CONCLUSION: Gait training with auditory feedback and functional electrical stimulation can improve the balance and gait performance in stroke patients. Therefore, in the future, gait training with auditory feedback and functional electrical stimulation therapy may be suggested as a gait rehabilitation training tool for stroke patients.

The effects of noise exposure are of two types: Nonauditory effects and auditory effects. Nonauditory effects of noise exposure are interference with communication by speech, sleeping and emotional behavior. The noise will cause the high blood pressure and rapid pulse, also that decrease the salivation and gastric juice. in experimentaly showed that the Corticoid hormon: Gonatotropic hormone were decrease and Thyrotropic hormoone is increase. Auditory effect of noise exposure. when the normal ear is exposed to noise at noise at hamful intensities (above 90㏈) for sufficiently long periods of time, a temoral depression of hearing results, disappearing after minutes or hours of rest. When the exposure longer or intesity greater is reached the Permanent threshold shift called noise-induced hearing loss. Hearing loss resulting from noise exposure presents legal as well as medical problems. The otologist who examines and evaluates the industrial hearing loss cases must be properly informed, not only concerning the otologic but also about the physical and legal aspects of the problems. The measurement of hearing ability is the most important part of a hearing conservation, both preplacement and periodic follow-up tests of hearing. The ideal hearing conservation program would be able to reduce or eliminate the hazardous noise at its source or by acoustic isolation of noisy working area and two ear protections (plugs and muff type) were developed for personal protection.

With the media's shift into the digital era in the 2000s, comic book publishers attempted a transition into the new medium by establishing a distribution structure using internet networks. But that effort shied from escaping the parallel-page reading structure of traditional comics. On the other hand, webtoons are showing divers changes by redesigning the structure of traditional sequential art media; they tend to separate and allot spaces according to the vertical scroll reading method of the internet browser and include animations, sound effects and background music. This trend is also in accordance with the preferences of modern readers. Modern society has complicated social structures with the development of various media; the public is therefore exposed to different stimuli and shows characteristics of differentiated perceptions. In other words, webtoons display more relevant and entertaining characteristics by inserting sounds and using moving texts and characters in specific frames, while traditional comics require an appreciation of withdrawal and immersion like other published media. Motions in webtoons are partially applied for dramatic tension or to create an effective expression of action. For example, hand-drawn animation is adopted to express motions by dividing motion images into many layers. Sounds are also utilized, such as background music with episode-related lyrics, melodies, ambient sounds and motion-related sound effects. In addition, webtoons provide readers with new amusement by giving tactile stimuli via the vibration of a smart phone. As stated above, the vertical direction, time-based nature of animation motions and tactile stimuli used in webtoons are differentiated from published comics. However, webtoons' utilization of innovative techniques hasn't yet reached its full potential. In addition to the fact that the software used for webtoon effects is operationally complex, this is a transitional phenomenon since there is still a lack of technical understanding of animation and sound application amongst the general public. For example, a sound might be programmed to play when a specific frame scrolls into view on the monitor, but the frame may be scrolled faster or slower than the author intended; in this case, sound can end before or after a reader sees the whole image. The motion of each frame is also programmed to start in a similar fashion. Therefore, a reader's scroll speed is related to the motion's speed. For this reason, motions might miss the intended timing and be unnatural because they are played out of context. Also, finished sound effects can disturb the concentration of readers. These problems come from a shortage of continuity; to solve these, naturally activated consecutive sounds or animations, like the simple rotation of joints when a character moves, is required.
