The purpose of this study is to estimate human sensibility quantitatively under color and music stimulation and to examine the correlation between visual and auditory emotion. We measured biological signals such as EEG, ECG, skin conductance and the number of respiration in order to compare color with music sensibilities. Our result showed that red, yellow and violet color provoked active and exciting senses dominatively as dance, rock and blues music. While blue, cyan and pink color were involved in tranquil and resting emotions deeply as classic and ballade music. Our quantitative estimations of human sensibilites are useful in the design of manufactured goods.

본 논문에서는 학습 과제 수행 시 청각 자극이 뇌에 미치는 영향을 확인하기 위하여 뇌파 계측 실험을 통해 얻은 데이터로 분석한 결과를 제시하였다. 피험자가 수학적 과제를 해결하는 동안, 피험자의 선호도에 따라 구분한 선호 음악 및 비선호 음악을 청각 자극으로 제시하였으며, 수학적 과제는 암기형 및 절차형 과제로 구분하여 뇌파를 측정하였다. 이를 집중력과 관련된 뇌파의 주파수 대역인 세타파, SMR파 및 중간베타파로 나누어 상대 파워 스펙트럼 값을 비교하였다. 본 논문의 결과로는 무음악과 선호 음악 및 무음악과 비선호 음악을 비교한 경우에서 유의한 차이를 나타내는 채널을 관측할 수 있었으며, 공통적으로 전두엽 부위의 채널인 F3 및 F4에서 평균의 차이를 나타냈다. 유의미한 차이를 나타낸 채널들에서도 음악이 없는 경우보다 음악이 제시된 경우의 파워가 더 크게 나타났으며, 선호도에 따라서는 선호 음악이 비선호 음악의 경우보다 두뇌의 활성도가 크게 나타난다는 사실을 실험결과로부터 확인할 수 있었다.

The purpose of this study is to analyze the effects of the auditory stimulation using pop music on EEG. The subjects in the study were eight healthy university students; five men and three women, age group of 22-28 years old. EEGs were measured for one minute at 19 channels, according to the international 10-20 system method, after both pop musics which the subject likes and not were provided with 100% and 50% volume of standard value, respectively, and the ratio of $\beta$/$\alpha$ was obtained. As a result, when the subjects heard their favorite music, the values of $\beta$/$\alpha$ ratio at the Right-Parietal.Temporal.Occipital lob(T6, O2) showed to be lower than stable state in the situation with 50% volume of standard value.

개인마다 소음, 음악과 음향진동 자극에 대한 인체의 반응은 상당한 차이가 발생하는 것을 고려하여 뇌파 파워의 상대적인 비율로 비교.고찰하였다. 우선 강한 소음 자극에 대한 뇌파의 변화는 긴장과 스트레스 증가를 의미하는 베타파의 증가 및 긴장완화와 안정을 의미하는 알파파의 감소를 보였고, 좋은 자극에 대해서는 그 반대의 효과를 보였다. 즉, 좋은 자극에 의한 스트레스저감의 효과가 있음을 확인하였다. 자극 후의 변화에서는 좋은 자극시와 마찬가지로 대체로 알파파가 증가하는 경향이 있지만 이와 반대의 경우도 발생하고있어 이 역시 개인차가 있음을 알았다.

Objective: This study was to compares and analyzes programs applied to improve cognitive function in patients with mild cognitive impairment and early dementia in the community to find out their effectiveness. Methods: In this study, 12 papers were finalized by searching for "elderly", "cognitive", "community", and "program" using the database of the Research Information System (RISS), National Assembly Library, and Korean Studies Information (KISS). Results: Programs for cognitive function were in the order of cognitive stimulation program, arts and crafts, and exercise program. In the program, rather than applying the cognitive stimulation program alone, the program was operated by combining leisure or exercise, music, art, and handicraft. The time was shown to be 30 minutes. The most frequently used evaluation tool was MMSE, followed by GDS and BBS. By cognitive domain, cognitive stimulation program and memory, satisfaction in psychology, and balance ability in exercise were evaluated the most. In the cognitive area, various cognitive stimulation areas were included, and in the exercise area, basic exercise, muscle strength exercise, joint exercise, and balance exercise were applied. Conclusion: Therefore, developing a program to improve cognitive function for mild cognitive impairment, it will be possible to prepare guidelines to establish and development.

The expressions of c-Fos and nitric oxide synthase (NOS) represent neuronal activity and play' a crucial role in the shaping of the development of brain. During the late pregnancy, stresses may influence neuronal activity of prenatal rats. In the present study, the effects of prenatal noise and music on the expressions of c-Fos and NOS in the hippocampus of rat pups were investigated. Exposure to the noise during pregnancy decreased c-Fos and NOS expressions in the hippocampus of rat pups, whereas exposure to music during pregnancy increased c-Fos and NOS expressions in the hippocampus of rat pups. The present results show that prenatal music stimulation may increase neuronal activity of rat offspring, whereas exposure to noise during pregnancy may reduce the neuronal activity of offspring. The present study suggests that prenatal stimuli including noise and music could affect the fetal brain development.

본 연구는 소뇌 별아교세포종 발병으로 인해 소뇌 수술을 받은 12세 환아의 보행 기능 개선을 위해 RAS 보행훈련을 실시하여 보행인자의 변화를 관찰한 사례연구이다. 객관적 분석을 위해 VICON 370 Motion Analysis System을 이용한 동작분석을 RAS 보행 훈련 사전 사후에 실시하였다. 매 회기 30분씩 총 9회의 훈련을 실시한 결과 시공간적 지표 중 분속수, 보행속도, 보행시간, 보장, 활보장의 증가와 운동형상학적 지표의 움직임이 정상범주의 형상과 근접해가는 경향성을 나타내었다. 이는 RAS 보행훈련 후 보행의 효율성이 증진되는 것으로 해석될 수 있다. 이는 신체적 재활이 요구되는 여러 대상군에게 적용 가능성을 보여주었으며 효율성 검증을 위한 후속 연구가 요구된다.

Objectives : This study was conducted to assess effects of oriental medicine music therapy on heart rate variability(HRV) in normal subjects under mental stress. Methods : 34 healthy volunteers(control group:17, experimental group:17) participate in this study. The volunteers were randomly allocated into two groups. After 10-minutes rest period and instrumentation, both groups performed a mental stress test for 12-minutes. HRV was recorded before and after the mental stress. And then the experimental group applied oriental medicine music therapy for 10-minutes. In the control group, they rested for 10-minutes. And HRV was recorded. Results : After giving mental stress stimulation to both groups, LF and LF/HF ratio were significantly increased and HF, mean HRV were decreased. In experimental group, LF, LF/HF ratio were significantly decreased and HF, SDNN were significantly increased after applying oriental medicine music therapy. In control group, LF was significantly decreased. And LF/HF ratio was decreased and HF, SDNN were increased, but it was not significant. Conclusions : This results show that oriental medicine music therapy could be relatively useful to decrease sympathetic activity and prevent the alteration of autonomic nervous system due to mental stress.

In this paper, we present electroencephalography (EEG)-based power spectra analysis and auditory stimuli methods as coping mechanisms for disgust affection and phobia. Disgust affection is a negative emotion generated from trying to eliminate something harmful to one. It is usually related to mental illnesses such as obsessive-compulsive disorder, specifically phobia and depression. In our experiments, participants watched videos on horrible body mutilation and disgusting creatures, with either the original sound track or relaxing and exciting music as auditory stimulation. After watching the videos with original sound track, the participants watched the same video with a different audio background, such as soothing or cheerful music. We analyzed the EEG data utilizing relative power spectra and examined survey results of the participants. The results demonstrated that disgust affection is decreased when participants watched the video with relaxing or exciting music instead of the original soundtracks. Moreover, we confirmed that human's brainwave reacts according to types of audio and sources of disgust affection.

The special interest should be paid to the analysis of the influences of positive emotions in terms of their possible effects on the dyanmics of autonomic. recovery after the negative affective stimualtion. Taking into account emotion-specific autonomic response patterning and dissociation of parameters of autonomic arousal during experience of both positive and negative emotional states, this problem seems a challenging one. In present study several autonomic parameters were analyzed altogether, namely inedices of electrodermal activity, heart rate and respitation rate during consecutive combination or both IAPS-based visual affective and auditory stimulation. The aim of the study was analysis of patterns of electrodermal and cardiorespiratory responses during emotional states evoked by negative affective visual stimulation followed by positive or neutral auditory one with intention to identify if the latter is able to facilitate post-stress recovery and enhance restoration of pre-arousal levels. The main orientation was dirdcted towards the further application of experimentally induced comfort emotions for dampening the negative consequences of exposure to stressful stimuli.
