SBS <힐링캠프>의 배경음악과 음향효과는 다른 오락 프로그램과는 매우 차별적인 양상을 보인다는 점에 착목하여, 실제 프로그램에서 어떤 방식으로 작용하는 지 내용분석을 통해서 분석했다. 분석결과 <힐링캠프>는 다른 오락 프로그램과는 비교할 수 없을 만큼 많은 양을 사용한다는 것을 확인했다. 즉, 전체 텍스트에서 음악과 음향효과가 차지하는 비중이 상대적으로 크다는 것을 알 수 있었다. 또한 <힐링캠프>의 배경음악과 음향효과는 동어반복적인 정보제공적 기능, 다양한 의미 중에 한 가지를 선택하여 강조하는 감정고조 혹은 정박의 기능, 텍스트에 나와 있지 않은 이야기를 풀어가는 서술 혹은 중계의 기능을 수행하는 것을 알 수 있었다. 텔레비전 자막이 수행하던 기능을 음악과 음향효과가 그대로 이어받고 있는 것이다. 물론 이러한 음악과 음향효과의 활용이 시청자의 관심을 끌고 주의를 집중시켜 시청률 상승의 효과를 가져올 것이라 예상되지만, 다른 오락프로그램과는 달리 매우 적극적이고 체계적인 활용을 통해서 오락프로그램 서사의 새로운 차원을 열어가고 있음을 확인할 수 있었다.

Purpose: The aim of this study was to ascertain the effects of the lower extremity muscle strengthening exercise on balance and ambulation of children with cerebral palsy. Methods: 10 subjects who participated in this research undertook the 12-week the lower extremity muscle strengthening exercise program, which consisted of a series of mat exercises and sling exercises. The statistical significances were examined by using Wilcoxon signed-rank test, a non-parametric test, for evaluating the improvement of balance and ambulation of the subjects. In order to evaluate the correlation among the variables, Pearson's correlation coefficients were also calculated. In all statistical analyses the significance level was selected as ${\alpha}$=0.05. Results: Berg balance scale(BBS) was significantly increased after the intervention(p<.05). Percentage weight bearing(PWB) was decreased after the intervention, but there was no significant difference. Time up and go test(TUG) value was significantly decreased(p<.05). Gait velocities was increased after the intervention, but there was no significance. Stride length, step lengths of the affected side and the sound side were significantly increased after the intervention(p<.05). In the correlation analyses of the measures before the intervention, TUG had significant negative correlation to BBS and gait velocity(p<.05). Stride length, step lengths of the sound side and the affected side had significant positive correlation between themselves(p<.01). In the correlation analyses of the measures after the intervention, TUG had significant negative correlation to BBS and gait velocity(p<.05). BBS revealed significant positive correlations to stride length, step lengths of the sound side and the affected side(p<.05). Stride length, step lengths of the sound side and the affected side had significant positive correlation between themselves(p<.01). Conclusion: Based upon the outcomes as above, it is likely that the muscle strength exercises have substantial effects on balance and ambulation of children with cerebral palsy. Thus various lower extremity muscle strengthening exercise programs are required to be studied and developed in order to contribute to functional improvements of children with cerebral palsy.

It has been considered that scattered sounds have a positive effect on a hearing impression of a sound filed. This study investigates the degree and the quality of a scattered sound field by using the acoustical parameters and autocorrelation function(ACF) of impulse responses. The acoustical parameters and fine structure of the ACF of an impulse response were used for the evaluation of the scattered sound field. The relationship between the scattering coefficient of surfaces with various hemisphere diffuser configurations and the acoustical parameters and ACF parameters of impulse responses was investigated.

In order to investigate psychoacoustic characteristics of fibers, and to compare them with sound physical parameters, each sound of 25 different fabrics consisted of a single fiber such as wool, cotton, silk, polyester, and nylon was recorded. Sounds of specimens were transformed into critical band diagram and psychoacoustic characteristics including loudness and sharpness for each sound were calculated based on Zwicker＇s models. Physical parameters such as the level pressure of total sound (LPT), level ranges (ΔL), frequency differences (Δf), AR coefficients (ARC, ARF, ARE) were obtained in fast fourier transform (FFT) spectrum. Nylon taffeta showed higher values for loudness than 2.5 sone corresponding to human low conversation, while most silk fibers generated less louder showing lower values for loudness than 1.0 sone. Wool fibers had higher loudness mean value than that of cotton, while the two fibers didn't differ in LPT. Loudness showed high positive correlation coefficients with both LPT and ARC. Sharpness values were higher for wool fiber group than other fibers. Sharpness was not concerned with loudness, LPT, and ARC, but the fabrics with higher values for sharpness tended to show higher ΔL.

This paper addresses a new technique of measuring the mean flow velocity over the cross sectional area of the pipe using sound field reconstruction. When fluid flows in the pipe and two plane waves propagate oppositely through the medium, the flow velocity causes the change of wave number of the plane waves. The wave number of the positive going plane wave decreases and that of negative going one increases in comparison to static medium in the pipe. Theoretical backgrounds of this method are introduced in detail and the measurement of mean flow velocity using the sound field reconstruction is not affected by velocity profile upstream of microphones.

To inspect how the different sensitivities in BAS (or BIS) moderate on the HRV pattern stimulated by positive or negative affective sound, we measured the electrocardiogram (ECG) of 25 students, consisted of 4 groups depending on the BAS (or BIS) sensitivity, while listening music or being exposed to noise. The power spectral density of HRV was derived from the ECG, and the power of HRV was calculated for 3 major frequency ranges (low frequency [LF], medium frequency [MF], and high frequency [HF]). We found that the index MF/(LF+HF), while listening music, was 20 % higher in the individuals with a low BIS but high BAS than in the individuals with a low sensitivity In both BIS and BAS. Moreover, in the former group this index was 30 % higher while listening music than while being exposed to noise. From these results we suggest that individuals with a low BIS but high BAS be more sensitive to positive affective stimuli than other groups, and the index MF/(LF+HF) be applicable to evaluate positive affects.

Purpose: The purpose of this research was to examine the effect of the sensoryscape (sport fans' stadium experiences via the five senses) on connectedness and elation that sport fans have about their teams. Research design, data, and methodology: To achieve this purpose, structural equation modeling was conducted with a total of 417 KBO baseball fans. Results: The results of the research are as follows. First, stadium experiences via sport fans' sight, sound, and touch had positive effects on connectedness that consists of passion, nostalgia, supportive, and connected. Second, stadium experiences via sport fans' sight, sound, and taste had positive effects on elation that consists of happy, excited, pleased, proud, optimistic, and entertained. Conclusions: This research provides the first empirical evidence of the effects of sport fans' sensory experiences on emotions associated with sport teams. In order to maximize connectedness and elation that sport fans have about their teams, sport marketers need to develop specific sensory strategies that affect stadium experiences. Further implications were discussed.

Objectives: There are substantial variations on the methods of identifying Sa-sang typology in clinical practice. This review aimed to describe the clinical experiences on the classification of Sa-sang typology based on index signs for practice of Tae-Geuk acupuncture. Methods: Core physical signs and interpretation of treatment response for the classification of Sa-sang typology are suggested based on 42-year clinical experiences of the expert (the first author). Results: Epigastric tenderness and hepatic dullness sound are the most important physical sign in the classification of Sa-sang typology. Clinical experiences indicate that there may be a positive association between the presence of epigastric tenderness and hepatic dullness sound. Four sets of acupuncture points are matched for four types of Sa-sang institution, respectively. Appropriate match will resolve epigastric tenderness and hepatic dullness sound, while this will not happen if inappropriate match is employed. Conclusion: I suggest that two physical signs (i.e., epigastric tenderness and hepatic dullness sound) are essential for the classification of Sa-sang typology in Tae-Geuk acupuncture.

This study examines the rustling sound characteristics of electrospun nanofiber web laminates according to layer structures. This study assesses mechanical properties and frictional sounds (such as SPL); in addition, Zwicker's psychoacoustic parameters (such as Loudness (Z), Sharpness (Z), Roughness (Z), and Fluctuation strength (Z)) were calculated using the Sound Quality Program (ver.3.2, B&K, Denmark). The result determined how to control these characteristics and minimize rustling sounds. A total of 3 specimens' frictional sound (generated at 0.63 m/s) was recorded using a Simulator for Frictional Sound of Fabrics (Korea Patent No. 10-2008-0105524) and SPLs were analyzed with a Fast Fourier Transformation (FFT). The mechanical properties of fabrics were measured with a KES-FB system. The SPL value of the sound spectrum showed 6.84~58.47dB at 0~17,500Hz. The SPL value was 61.2dB for the 2-layer PU nanofiber web laminates layered on densely woven PET(C1) and was the highest at 65.1dB for the 3-layer PU nanofiber web laminates (C3). Based on SPSS 18.0, it was shown that there is a correlation between mechanical properties and psychoacoustic characteristics. Tensile properties (LT), weight (T), and bending properties (2HB) showed a high correlation with psychoacoustic characteristics. Tensile linearity (LT) with Loudness (Z) showed a negative correlation coefficient; however, weight (T) with Sharpness (Z) and Roughness (Z), and bending hysteresis (2HB) with Roughness (Z) indicated positive correlation coefficients, respectively.

This paper present as experimental demonstratio of DSP and a sensory actuator that is used to actively control sound transmission/radiation through a vibrating plate. A plane acoustic wave incident on a clamped, thin circular plate was used as a noise source, and a sensory actuator bounded to the plate was used to control and sense vibration of the plate. The sound transmission reduction problem was tranformed as a structural vibration control problem that actively control the structural vibration modes coupled to acoustic modes. The results show that the first structural vibration mode is controlled with a reduction of 78 percent in the displacement and velocity of the plate. This corresponds to a 13dB reduction in the acoustic response. These experimental results indicate that a sensory actuator bounded to the plate can be employed to attenuate the sound transmitted to radiated from the plate.
