The purpose of this study was to investigate relationship among the depression, physical condition, daily living activities, and sleep state among old people at elderly care facilities. The subjects include old people aged 65 or older residing at an elderly care facility. At elderly care facilities, the depression of old people was related with the state of vision, mastication ability, quality of sleep, and sleep state. The degree of relation was high in the group with a poor vision, the one with a bad condition of teeth, the one that considered their quality of sleep to be poor, and the one with somnipathy. Their depression had negative correlations with age and positive ones with mastication ability and assessment of quality of sleep. At elderly care facilities, the depression of old people was highly connected with the state of vision, mastication ability, sleep state, and hearing ability. In short, the depression of old people at elderly care facilities is highly connected to the health state perceived individually. The findings point to the importance of close interest in individual health state and management of old people in poor vision, mastication ability in healthcare and nursing intervention.

Objective : This study aims to identify the self-reported driving abilities of elderly drivers and their correlations to the demographic factors that influence them, and to verify the adequacy of the hypothetical model, constructed based on vision, auditory, cognition, motor, and psychological factors, in order to present a path model on the self-reported driving abilities of elderly drivers. Methods : The participants in this study were 122 elderly drivers aged 65 years or older residing in the community. This study evaluated the following factors of the participants: Vision and hearing, motor ability, cognitive ability, depression, self-reported driving abilities. Results : The results of this study are as follows. In the case of men, the self-reported driving ability score was higher than for women, and those driving 6-7 days per week had higher scores than those driving 3 days or less. The period of holding a driver's license and driving experience positively correlated with self-reported driving abilities. The final model of factors influencing the self-reported driving abilities of elderly drivers had a p value (.911) exceeding .05; TLI (1.202), NFI (.949), and CFI (1.000) of over .90; and RMSEA (.000) of lower than 0.1, indicating that the hypothesis model fit the data well. First, the directly influential factors on the self-reported driving abilities of elderly drivers were depression, decreased hearing, and grip strength. Second, age was found to have a direct influence on depression and grip strength; moreover, depression and grip strength as a mediator indirectly influenced their self-reported driving abilities. Third, depression was found to have a direct influence on their delayed cognitive processing and grip strength. Conclusion : The significance of this study is in the identification of direct and indirect factors influencing the self-reported driving abilities of elderly drivers in regional communities, and in the verification of multi-dimensional effects of diverse factors influencing such abilities.

In order to obtain the fundamental data on the auditory thresholds of fishes for catching method using low frequency sound, the auditory thresholds of coralfish Chromis notatus were measured in the presence of masking noise in the spectrum level range of 73~83dB re l$\mu$Pa/√Hz by heartbeat conditioning technique using pure tones coupled with a delayed electric shock. Critical ratios were about 23~41dB at measurement frequency, The critical ratio increased almost linearly with increasing frequency from 500Hz. The noise spectrum level at the start of masking was about 60~65dB. This suggests that hearing of coralfish is masked in the natural environment with the noise spectrum level above 60dB. The sound pressure level of which the signal sound of 300Hz is recognized by coralfish under the ambient noise is above 88dB and the critical ratio of them is above 23dB. The hearing index of coralfish with ambient noise was 81.

The purpose of this study was to examine the effects of the activity constraints due to disability on subjective health status and daily life satisfaction among disabled, and mediating effects of subjective health status on the relationship between activity constraints due to disability and daily life satisfaction. For this purpose, the response data of 3,809 people who participated in the 5th year of the 2nd Wave of the Panel Survey of Employment for the Disabled (PSED) were used and analyzed. As a result, all sub-factors except for the degree of difficulties in hearing even when using hearing aids among activity constraints due to disability has a statistically significant negative effect on subjective health status, and all sub-factors has a significant negative effect on daily life satisfaction. And, subjective health status has a significant partial mediating effect on the relationship between all sub-factors except for the degree of difficulties in hearing even when using hearing aids among activity constraints due to disability and daily life satisfaction. Therefore, the level of activity constraint for the disabled should be reduced by providing systematic and differentiated customized rehabilitation programs that take into account the disability characteristics of the disabled, thereby improving the health level and social independence ability of the disabled. Furthermore, in order to improve the daily life satisfaction of the disabled, it is necessary to provide policy support such as the establishment of a community-based integrated support system for the disabled by linked rehabilitation program and health promotion program.

Objectives: The purpose of this study was to investigate the clinical application of oriental medical therapy to a patient with memory disorders and quadriparesis caused by traffic accident. Methods: This study was carried out on a patient who was admitted to the Sangji oriental medical hospital, from January 21st in 2002 to May 2nd in 2002. We used 4 kinds of diagnosis(watching, asking, hearing, and toughing) and treated the patient with herbal medication and acupuncture therapy. Then we estimated the effect of memory disorders through MMSE-K(Mini mental State Examination-Korea) and K-DRS(Korean-Dementia Rating Scale). The numerical effect demonstrated ability of movement through range of motion. Results: Following the treatment the patient's mental state and the ability of movement improved. Conclusions: The present results suggest that oriental medical therapy has the positive effects on a patient with memory disorders and quadriparesis which were caused by traffic accident.

Purpose: This study aimed to determine how inclined-treadmill walking training with rhythmic auditory stimulation affects balance and gait in stroke patients. Methods: Ten chronic stroke patients, admitted to B hospital in Gangwon-do between August and October 2015, were trained 5 times per week for 4 weeks; each session lasted 30 minutes. To assess balance and gait before and after the training, the timed up and go (TUG) test, Berg balance scale (BBS), six minute walking test (6MWT), and three-dimensional spatiotemporal gait ability were used to measure the relevant variables. The data were analyzed using the paired t-test, and the statistical significance level was 0.05. Results: There were significant differences in the TUG, BBS, 6MWT, gait speed, cadence, single limb support (SLS), and symmetric index (SI) before and after training (p < 0.05). Conclusion: The results showed that the inclined-treadmill walking training with rhythmic auditory stimulation was effective at improving the balance and walking ability of stroke patients. Hearing training, using one of the basic procedures of proprioceptive neuromuscular stimulation, is considered to be an important aspect.

The Connected Speech Test (CST) was developed to test hearing aid performance using realistic stimuli (Connected speech) presented in a background of noise with a visible speaker. The CST has not been investigated as a measure of speech reading ability using the visual portion of the CST only. Thirty subjects were administered the 48 test lists of the CST using visual presentation mode only. Statistically significant differences were found between the 48 test lists and between the 12 passages of the CST (48 passages divided into 12 groups of 4 lists which were averaged.). No significant differences were found between male and female subjects; however, in all but one case, females scored better than males. No significant differences were found between students in communication disorders and students in other departments. Intra- and inter-subject variability across test lists and passages was high. Suggestions for further research include changing the scoring of the CST to be more contextually based and changing the speaker for the CST.
