The aim of this study is to establish the indoor noise limits of apartment houses for mad traffic noise. To achieve this goal, psycho-acoustic experiments were carried out with the mad traffic sound sources modulated by the transmission loss characteristics of the external windows. As a result of this study, followings are suggested. 1) On correlation between dose level and psycho-acoustical response, the initial level of negative feeling is located on $40.1{\sim}40.6$ Leq dB(A). 2) On the degree of satisfaction to road traffic noise, near 35% Point being same dissatisfaction degree is to be assumed $40{\sim}41$ dB(A) of indoor noise level presented into three vocabulary. It is suggested to be reasonable level of 40 dB(A) on the indoor noise limits for intruding road traffic noise, and it is appropriate to be the 5dB level difference between grades.

The purpose of this study is to understand how visual factors of healthcare facilities would have an effect on psycho-physiological health of inpatients. First, visual factors of a ward, where inpatients mostly spend their time in a hospital, were extracted in order to find out how visual environment would affect inpatient's health. Then experimental samples were made and inpatients' reactions against them were analyzed. This study is composed of two approaches a questionnaire for psychological analysis and an electroencephalogram measurement for physiological analysis. The results of this experiment show that psycho-physiological health of subject's can be remarkably improved according to artificial arrangement of visual environment of a ward. Especially, they also show that insignificant changes of visual environment such as furnishing trees, flowerpots or framed pictures in a ward, where there is no view and completely closed, will be able to exert a range of positive effects on an subject's psycho-physiological health. In conclusion, further studies need to be delivered about indoor designs to positively bring in natural elements to a ward as well as visibility ratio of views and skylines from a ward.

The study examined that parents and teachers were aware of what extents behavioral characteristics were related to the children's voice problems. The voice samples of 89 children in the ages of 3 to 5 were collected and their voice quality were graded by G scale of GRBAS. The parents and teachers of the children were asked to complete the questionnaire composed of the pediatric Voice Handicap Index (pVHI) and the psycho- and voice behavioral characteristics of their children. The results are as follows. First, there were no significant differences in both pVHI and behavioral characteristics of their children by G scale. However, significant differences were shown in the behavioral characteristics between parents and teachers, but no difference in pVHI between them. In addition, there was a significant correlation between the psycho-behavioral characteristics and the voice behavioral characteristics in both parents and teachers. These results represent that parents and teachers are not aware of the presence of their children's voice problems and such voice problems are affected by behavioral characteristics associated with the use of voice.

Objectives : The purpose of this study was to examine the relationship of stress symptoms, oral habits and temporomanbibular joint symptom among 20-30 ages adults. And it's also meant to investigate the direct and indirect influence of these factors by using a path model to determine their causal relationship. Methods : The subjects in this study were 287 selected 20-30 ages adults, on whom a survey was conducted from June 15 to July 10, 2014. The data were analyzed using SPSS 18.0(SPSS 18.0 K for window, SPSS Inc USA) and IBM SPSS Amos 18.0(SPSS Inc, Chicago, IL, USA). Results : There were significant differences in oral habits, TMJ symptoms and stress according to gender. There were significant differences in oral habits, TMJ symptoms, physical and psycho-emotional symptoms according to Systemic disease. And stress, physical, psycho-emotional symptoms, oral habits and TMJ symptoms were correlated to one another. Stress exerted a direct influence on physical, psycho-emotional symptoms, and psycho-emotional symptoms had a direct impact on physical symptoms, oral habits and TMJ symptoms. Physical symptoms exercised a direct influence on oral habits and TMJ symptoms, and oral habits affected TMJ symptoms in a direct way. physical, psycho-emotional symptoms and oral habits served as parameters that produced partial mediation effects, and the two factors had an indirect impact on TMJ symptoms. Conclusions : It's found that stress exerted direct and indirect influence on oral parafunction and TMJ symptoms. Like other diseases, oral habits and TMJ symptom that stem from stress is likely to lead to chronic diseases if the two are not noticed at the right time. Therefore individual people should try to get rid of stress in a manner to be appropriate for their own characteristics in order to maintain their oral health.

This study deals with the psycho-social development of children raised by disabled parents. In particular, we are willing to examine the influence of parental factors such as social engagement and future forecast on the change of children's psycho-social development. Using the three waves of Korean Welfare Panel Study data, these predictors were examined through the Latent Growth Curve Modeling. The result shows that parent's disability has a negative influence on their children's psycho-social development. However, similar to the findings of the previous studies, the degree of this influence tends to be decreased as children grow up. Lastly, two parental factors have a direct influence on the psychological development of children. Furthermore, parent's social engagement has an indirect influence on the change of sociality of children through the psychological change of them. This result means that we should encourage disabled parents to participate actively in social activities and think positively about their future.

This study conducted a preliminary survey to study humanities healing methods for college students. Based on the student survey, we would like to present the research direction of humanities healing and find an appropriate humanities healing method. For quantitative analysis, 10 questions were constructed, focusing on BPS-Modell, Bio, Psycho, and Sozio of life. In the question of the Bio, 50% of the students said they understood their body, mind, and will and acted accordingly, but 20% of the students showed that their actions according to their body, mind, and will did not fit. In the question of Psycho, more than 50% of students said they communicated well with their inner selves, but less than 20% of students did not. In the question of Sozio of life, more than 60% of students form a social network well, but about 10% of students have very low attitudes or meanings toward life. The ultimate purpose of humanities is 'happiness', and the purpose of human life is also 'happiness'. We hope that the power of positivity to realize a stable future society and improve the quality of life will be expanded through humanities healing.

A fire is occurring increasingly every you and the damage is bigger in proportion to the number. Therefore a fire is classified as a serious calamity. It is important to evacuate and fight a fire by early Perception. However, if the alarming sound is not perceived when a fire breaks out the damage could be expanded. From this point of view, this study aims to analyse the correlation between alarming sound sources and sound quality parameters through psycho-acoustic experiment using Korean vocabularies extracted by existing study. The sound sources more dangerous, tense and urgent were chosen. The results from this study are as follows: 1. airraid, klaxon2 and S.O.S got a point more than conventional alarming sound.2. correlation coefficient between Loudness(L) and Unbiased Annoyance(UA) was highest with 0.63 md Sharpness(S) and Roughness(R) was -0.40 and Fluctuation Strength(FL) and Tonality(T).
