This study was designed and performed to identify the effects of oriental medical therapy on hwabyung patients by investigating the life events as the cause of Hwabyung, recent stress perception which influences the clinical appearances and change of symptoms by means of objective scales. 1. Through life events rating scale, life events are reported as follows, in the order of majority. Health, discord within family, martial life, friendship and interest, religion etc. Hwabyung patients experienced negative stress much more than positive stress. 2. Through the GARS (Global Assessment of Recent Stress), there were some significant decreases of stress perception in stress4(stress of sickness or injury), stress7(stress of change or no change in routine) and stress8(overall global stress)(p<0.05, respectively), but there were no significant decreases in five items out of eight items. 3. There were significant decreases of all rated symptoms(feeling of chest oppressed, stuffy in the chest or epigastric mass, feeling of something pushing-up, flushing of body or face, abrupt impulsion of anger, resentment), which were checked weekly for 4 times (p<0.05, respectively). In this study the symptoms of hwabyung were improved regardless of stress perception. It means that hwabyung can be improved significantly with oriental medical therapy.

Objective: While one of the most prevailing motivations for seeking orthodontic treatment is to achieve good facial esthetics, understanding the level of a person's perception to the changes that have occurred on the face after orthodontic treatment is critical to the process of orthodontic diagnosis and treatment planning. Methods: 40 students attending art school participated in determining the level of their perception of changed lip position and facial asymmetry. Computer-graphic frontal face and facial profile photographs with balanced proportions were used to evaluate the level of a participant's perception of the changes in facia! asymmetry and in lip position. Results: Change of lip position over 2 mm and over a 3 mm change of facial asymmetry was perceived significantly. Conclusion: The results indicated that at least a 2 mm change of lip position was needed to be perceived after orthodontic treatment. The level of perception of the change in facial asymmetry was lower than that of the change in lip position. Information about facial changes given prior to the evaluation enhanced the level of perception.

The purpose of this study is improving the teachers' self-efficacy for pre-secondary music teachers. The research questions for this study were the improvement for teachers' self-efficacy for pre-secondary music teachers and the pre-secondary music teachers' perception about peer mentoring. In this study performed the interview and analyzed the in self-reflection journal in order to identify the improvement effect of teachers' self-efficacy and the participants' perception change in the peer mentoring. As the results from analyzing the change in participant's perception about peer mentoring the mentors had the opportunity to review previous learning contents and practice experiences while developing their team activity and for the mentees. Mentees said that they were given various help from the mentors' advices and their interactions and communication with mentors. From these results, it could identify that there was positive change in participant's perception about the peer mentoring. Based on these results, this study analyzed that it would need to require some chances for pre-secondary music teachers to be given some educational practice and field experience utilizing various teaching methods in order to improve their self-efficacy and the perception of peer mentoring.

Phantom phenomena on the signal light was observed and change of perception-reaction time of the observer was measured. If phantom phenomena occurs, signal light perception- reaction time by the drivers is prolonged, the extent of which may disturb driving. Length of the perception-reaction time is affected by the luminance contrast between the turned-on and tuned-off signals. Based on the measured results, several methods to prevent phantom phenomena were suggested.

This study suggests the optimum interior environment by projecting the criteria to design the living space light-ing that select the lighting environment among the sever-al environmental factors that influenced on the human perception. As a correspondance between the visual perception and the lighting, visual perception process, vision system, and visual perception system are investigated to compre-hend the lighting, and then conceptual contour of the lighting environments are presented which are transmit-ted the visual informations. As a lighting factors which are influenced on the visu-al perception, light source color is analized. Foundationally, the effect of the lighting methods and the techniques are investigated, and the changes of the lighting methods which influences on the space perception are examined through the previous results. As the changing the light sources color, the changing the subjective feelings of space perception through the ex-periment. This study is concluded with the proposition of the ef-fective lighting and the importance of the lighting envi-ronment.

This study was conducted using a multiple regression model to empirically analyze the impact of personal emotions and social change perceptions of pandemic experienced by Korean people in the COVID-19 situation on the perception of disaster response after the endemic. For this end, we used the survey data with 996 respondents on 「Daily Changes of the People After COVID-19」conducted by the Korea Press Promotion Foundation. The results showed that COVID-19 positive emotions and social change perception factors had a positive (+) effect on disaster response perception, while the sense of community had a moderating effect that alleviated COVID-19 negative emotions which had a negative (-) effect. The most influential factors on disaster response perception after the endemic were COVID-19 positive emotions and community sense that had pride and stability in Korean society during disaster situations. Therefore, this study suggests that systematic disaster response manuals and control towers that give the public pride and stability are more strongly requested for the government's prior and follow-up measures performed in the post-endemic disaster situation, and that the people are asked to have the community sense to overcome disasters together rather than to respond with personal actions and judgments.

Purpose : This study examined the effects of driving rehabilitation functional training on visual perception ability and driving reaction velocity. Those subjects were put under MVPT-3 test to see their visual perceptual functions before and after the 4weeks' driving rehabilitation function training and then put to TMT A-type test to see their driving reaction velocity performance. The followings are the results of this study. Methods : Using a driving simulator, driving rehabilitation functional training was performed targeting men and women aged in 20s 20 minutes per time, two times per week, for a month. Results : As for the change in visual perception, the Raw Score of MVPT-3 very significantly increased (p<.01), and the Standard Score also very significantly increased (p<.01). As for the change in reaction velocity, TMT A-type very significantly decreased (p<.01), and TMT B-type also very significantly decreased (p<.01). Conclusion : It could be found that driving rehabilitation functional training should be effective for both visual perception and reaction velocity. Consequently, the driving rehabilitation function training can be applied to clinics as training method for functional recovery and improvement of visual perceptual functions and driving reaction velocity performance ability of the patients. Thus, various functional programs should be studied in the future.
