Recently, in accordance with increase of the desire for Sports for All(Life Sports), the swimming pools in many areas are under construction. However, since they used many of the reflexible finish-materials on account of the characteristics of hydrophilic space, most of the Indoor Swimming Pools are generating the excessive reverberation. Such reverberation is bringing about the problem that obstructs the oral communication between the coach and the player, and the Clearness of Sound, besides the sport activity. On this viewpoint, on the object of the actually built indoor swimming pool, after the conduct of an optimized acoustics design by the remodeling through a computer simulation, and by carrying out the Psycho-Acoustics Experiment utilizing of Auralization Technique which is able to experience Virtual Sound Field at the stage of designing, then this thesis has attempted to appraise on the acoustic condition after the completion of construction. It is considered that such result of the study could be utilized as the useful data that enables to improve the curtailment effect of construction cost as well as the acoustic capability, by means of the presupposition control on the acoustic problem from the stage of design, for the occasion when the similar indoor swimming pool is planning to build, henceforth.

The influence of the visual information on the sound perception would be considerable. Furthermore, if the sound perception ranges in noisiness or annoyance beyond the loudness, it will depend much more on the shape of the visual information. This paper aims to estimate the influence of the several kinds of visual information on the perception of road traffic noise by means of the psycho-acoustic test method. The findings of present study on the influence of visual information on subjective noise perception are summarized as follows: Presenting visual images of mild and comfortable scenery reduced the noise perception reaction at the less noisy environments not exceeding 65 dB(A). At highly noisy environments exceeding 65 dB(A), however, the noise perception can be reduced by strong image of waterfall. Even eliminating the road traffic image may be helpful. Visual image of waterfall reduced the noise perception at all levels. It is inferred that the road traffic noise perception can be effectively ameliorated by presenting strong and real landscape images at any noisy environment.

In this study, the psycho-physiological response of drivers was investigated in terms of EEG(Electroencephalogram), especially with the fractal dimensions computed by Chaotic algorithm. The Chaotic algorithm Is well Known to sensitively analyze the non-linear information such as brain waves. An automobile with a fully equipped data acquisition system was used to collect the data. Ten healthy subjects participated in the experiment. EEG data were collected while subjects were driving the car between Won-ju and Shin-gal J.C. on Young-Dong highway The results were presented in terms of 3-Dimensional attractor to confirm the chaotic nature of the EEG data. The correlation dimension and fractal dimension were calculated to evaluate the complexity of the brain activity as the driving duration changes. In particular, the fractal dimension indicated a difference between the driving condition and non-driving condition while other spectral variables showed inconsistent results. Based upon the fractal dimension, drivers processed the most information at the beginning of the highway driving and the amount of brain activity gradually decreased and stabilized. No particular decrease of brain activity was observed even after 100 km driving. Considering the sensitivity and consistency of the analysis by Chaotic algorithm, the fractal dimension can be a useful parameter to evaluate the psycho-physiological responses of human brain at various driving conditions.

Purpose: This study was to investigate the gender difference of relationship between psycho-social factors ana smoking, drinking in adolescents. Method: The stratified cluster sample consisted of 925 adolescents. Data were collected from May to March 2002. The instruments used in this study were Perceived Stress, DES-D, Social Support and Self-Esteem. Results: The results showed that female had more perceived stress, depressed than male. Male had more social support network, smoke than female. Male who smoked cigarettes were more perceived stress, depressed than those who did not smoke. Female who smoked cigarettes were more social support network, and had less self-esteem than those who did not smoke. Also male who drank alcohol were more perceived stress, depressed than those who did not drank. Female who drank alcohol were perceived stress, depressed, social support network, and had less self-esteem than those who did not drank. Conclusion: It is hoped that much more research on gender difference in adolescents who smoked cigarettes, drank alcohol will be implemented in the future. In addition, it is suggested the application of various interventions to deal with drinking and smoking behavior among female and male adolescents.

Purpose: This study examined the prevalence of depressive symptoms and psycho-behavioral factors affecting depressive symptoms in patients with osteoarthritis. Methods: This cross-sectional study enrolled a convenience sample of 157 patients with osteoarthritis in a university hospital between March and December 2018. Depressive symptoms, osteoarthritis function, therapeutic self-efficacy, and health-related quality of life (QoL) were measured using structured questionnaires. Logistic regression analysis was used to investigate factors affecting depressive symptoms. Results: The mean age of participants was 73.3 years with 76.4% of them being women. The prevalence of depressive symptoms was 38.5%. Patients with depressive symptoms were more likely to be currently smoking and had an occupation and worse flexibility function associated with osteoarthritis. Whereas they were less likely to engage in regular physical activity and had a low level of therapeutic self-efficacy and perceived health-related QoL. Conclusion: Therapeutic self-efficacy to regular physical activity, including flexibility function may be primary factors influencing depressive symptoms in patients with osteoarthritis. With the management of osteoarthritis, psycho-behavioral factors should be considered in developing interventions to prevent depressive symptoms in patients with osteoarthritis.

Background: Music therapy is a common complementary and alternative therapy in addition to medical treatment for patients with cancer. If music therapy, which is known has a positive effect on human emotions and behaviors, is a useful additional therapy, it should be more integrated into pyscho-oncology. In this study, we aimed to determine medical oncologist attitudes to music therapy for patients with cancer and knowledge about musicology and music therapy in Turkey. Materials and Methods: This survey study included questions about participant attitudes and knowledge regarding music therapy as well as demographic characteristics. The population of the study were 402 physicians working in medical oncology in Turkey and the sample covered 112 participants in the the survey. For statistical analyses the chi-square test, Fischer exact test, and Mann-Whitney U analysis are applied. Results: In our study the rate for medical oncologists who were interested in music therapy was 28% (n=112). Some 30% (n=34) of medical oncologists recommended music therapy for their patients and 55% (n=61) recommended music therapy to prevent anxiety in patients with cancer. Conclusions: In this study, for more harmony with patients and in order to ensure management of adverse effect, it was concluded that music therapy should be regrded as an additional therapy in oncology clinics.

The architectural, facility makes the housing environment more pleasant, while too much noise coming from machinery room is detrimental to the workers physically and mentally. Therefore, more sound insulation and sound proof policies are increasingly required. However, as the annoyance caused by facility noise is influenced by various human listening characteristics as well as physical characteristics such as sound pressure level, it requires subjective evaluation characteristics through acoustic-psychological approach. For this purpose, the facility noise in the machinery room was actually measured and analyzed in the field to understand physical characteristics, and the correlation between physical evaluation value and psychological response value through listening test. Further, this study aims at presenting the data to set the standards of 'Just noticeable difference' of the facility noise together with reasonable evaluation with psychological reaction, through the grading of facility noise using trend formula. In the result, 13 stages of physical properties were forecasted for each evaluation method, together with 'Just noticeable difference' using the grading of architectural facility noise.

The dream is a well-known experience in the routine life. It is the image and thought being occurred during the sleep, and the complex reaction of our mental world to the event of everyday. In particular, there are so many opinions of the reason why people have a dream and this thesis is telling about the physical and pathological changes in the human as one of that various opinions. The aspects of this thesis are often founded in the diverse texts of oriental Medicine, including the Internal Classics(내경), and there were some cases that regarded the dream as diagnostic object and put to clinical uses. These attempts were not only tried out by particular orient thoght, also the ancient Greeks thought that the dream would represent important informations about the health. But, these ideas have been treated lightly by the impacts of the western medicine since the modern age. Straightforwardly, before the psycho-analytics was not development, most of the doctors and scientists regarded the dream as things like dregs of mind. The central operating bodies of the dream are the Spirit(신) and Hon and Beak(혼백), and the Spirit(신) is more essential part between the two.

Recently, creating a signature sound for a brand has become more important in the automotive industry. It is important to remember that the people inside a vehicle are not the only one, who assess the signature sound, exhaust sound has become a more important factor. Most research has used psycho-acoustic parameter to objectively measure the aesthetic qualities of exhaust sound. However, these results do not parallel the results from subjective analysis. Therefore, this research focused on developing a method for objective quantification to assess the aesthetic qualities of exhaust sound in order to help develop a more appealing signature sound. To do so, the actual exhaust sound was synthesized and subjectively assessed at varied frequencies samples of 30 individuals employed at sejong R&D center. The results were analyzed using the science of harmony scale.
