본 논문에서는 노인 대상자들이 신체적으로 기능의 상실, 경제능력의 상실, 사회성의 상실 신체적, 정신적으로 노령화 되어감에 따라 독립적으로 살아가는데 필수적으로 요구되는 활동을 할 수 있는 능력으로 자신의 신체를 돌보는 기술 및 행위와 우울과의 관계를 알아본 결과 경도 우울성향은 일상생활 수행능력이 약간 불편한 집단에서는 50.9%, 많이 불편한 집단에서는 57.1%로 나타났고, 중증도 우울성향은 일상생활 수행능력이 약간 불편한 집단에서는 13.2%, 많이 불편한 집단에서는 28.6%로 나타나서 유의미한 결과로 확인 되었다.

This study conducted the following experiment to examine change of physicopsychological function on Dynamic Trunk Control Exercise(3D-DTCE) and Static Trunk Control Exercise (STCE) to chronic low back pain patients subject for lumbago therapy and management. Physical function was measured by equlibrium and lumbar muscle activities and psychological function was measured by self-efficacy on comparative analysis of pre, post exercise and each groups in 30 lumbago patient subject. Equlibrium was measured by total, front back and left right sway index, lumbar muscle activities were measured by abdominal rectus and oblique abdominalis, erector spinae and self efficacy with lumbago patients was measured index of self efficacy. These result lead us to the conclusion that each group were statistically improved at all physicopsychological test. but equlibrium and lumbar muscle activities were more statistically improved at DTCE group and self efficacy with lumbago patients were not differanced on each group. Consequently, DTCE would be lead to positive increment of physical function more than STCE.

The purpose of this study was to analyze the degree of depression, cognitive function, communication ability, and the quantitative electroencephalogram (EEG) in elderly individuals with hearing loss and to investigate their inter-relationship. Hearing-impaired elderly participants, aged 60 years or older (37 men and 26 women) who visited the S Hearing Rehabilitation Center in Y City from June 20, 2020, to September 3, 2020, participated voluntarily after a recruitment announcement.The participants' overall characteristics, depression, and cognitive functions were evaluated with a structured questionnaire. The Word Recognition Score (WRS) was evaluated with an audiometer using the Korean Standard Monosyllabic Word Lists for Adults (KS-MWL-A). The quantitative EEG was measured with dry electrodes using a 2-channel EEG on the frontal lobes Fp1 and Fp2. The results are summarized as follows: Communication ability showed a positive correlation with the left-right symmetry of the frontal lobes (**p<.01) and a negative correlation with right-brain mental distraction and stress (*p<.05). In the difference WRS test for each group, the left-right symmetry of the frontal lobes (**p<.01) showed the greatest correlation with communication ability. Our results suggest that the left-right symmetry of the frontal lobes can be a biomarker indicative of the communication ability of older people with hearing impairments.

For knowing the effects of aging on conversational skills in daily communication, this paper studied for the conversational turn-taking skills, working memory and naming ability on healthy elderly adults over 65 ages. 85 elderly adults participated in this study, which divided into four groups by ages. Speech samples were collected in natural conversation. Memorization of numbers, mental calculation, repetition of words were administered for working memory test. K-BNT was used for the naming ability. One-way ANOVA analysis was used for the comparison of conversational turn-taking skills among four groups. We analyzed the correlation between conversational skills, working memory and naming ability. The results were as follows: first, there were a significant difference in conversational turn-taking skills by age, but not by gender. There was a significant difference in 'Turn-Taking Frequency' and 'Total Utterance Frequency' among four groups. The same results were shown in the scores of females within three groups(exclude groups over 85D)(p<.01). Second, there was a significant correlation between 'rates of maintenance' and 'naming ability'. In addition, it was found that the naming test predicted 'rates of maintenance' skills. The results of this study suggest that word-retrieval ability will be helpful to enhance functional communication skills in aging old adults.

본 연구는 집중력, 기억력 및 학습 능력의 뇌기능 증진을 위한 의식적인 손 운동에 관련된 연구이다. 우선 효과적인 재활을 위한 손가락 운동 패턴을 연구하였다. 단순한 손가락 운동(Simple Finger Movement ; SFM) 패턴과 의식적인 손가락 운동(Intentional Finger Movement ; IFM)패턴을 비교하였다. 다음으로 각각 두 패턴 운동을 시켜 피험자의 집중력과 학습 능력의 증진을 검증하고자 한다. SFM 패턴과 IFM 패턴의 비교와 집중력과 학습 능력의 증진의 검증은 뇌파(mid $\alpha$파)를 이용하였다. 실험은 먼저 SFM 패턴의 운동을 시키고 다음에 IFM 패턴의 운동을 시키는 실험을 하였다. 결과적으로 IFM 패턴에서 mid $\alpha$ 파의 증가가 이루어졌음을 측정함으로써, IFM 패턴이 뇌의 집중력과 학습 능력을 증진시킨다는 결과를 얻었다.

Currently, there are some aptitude test systems for older drivers in Korea. However, there are no methods and systems to evaluate the real driving ability for older drivers based on filed driving test. This study was conducted to investigate the availability to use the driving course test used for driving license for identifying difference in driving ability of older and non-older drivers. For the research purpose, filed experiments were conducted using the real driving course test site and evaluation times used in the field. In particular, driving behavior data that obtained from the experiments for two driver groups, older and non-older drivers, were analyzed and compared. From several statistical analyses of driving ability and vision and cognitive ability, it was found that the currently used driving course test site and evaluation times were not appropriated to identify driving ability deficiency of older drivers. To solve the problem, this study developed five evaluation items to identify driving ability deficiency of older drivers using the currently used driving course test site. It was also found that the developed five evaluation items have statistically significant correlation with vision and cognitive ability.

The purpose of this study is to analyze how it affects functional movement and dynamic balance applying Czech get up exercise based on the principle of motor development of child for office worker women in 30s and 40s. Through random allocation, an Czech get up exercise group(n=15) and a control group(n=14) were formed to apply exercise for 12 weeks, 3 times a week, and 60 minutes a day, and the control group maintained daily life at the same period. As a result of the study, showed that Deep squat(p<.05), Hurdle step(p<.01), In-line lunge(p<.05), Trunk stability push-up(p<.001), Rotary stability (p<.01), Total score(p<.001), were significantly in the Czech get up Group, and Dynamic Balance of Lower Extremity(p<.001), Right Dynamic Balance of Lower Extremity(p<.001) were also significantly in the Czech get up Group. In conclusion, it is thought that Czech get up exercise based on the principle of motor development of child will have a positive effect on the functional movement and dynamic balance in office women, thereby increasing work efficiency as well as healthy life.

In the self-healing group key distribution scheme, users are capable of recovering lost group keys on their own without requesting additional transmission from the group manager, where there is no reliable network infrastructure. In this paper, we propose a new self-healing group key distribution scheme with revocation capability, which is optimal in terms of user memory storage and more efficient in terms of communication complexity than the previous results. We obtain a slightly improved result from (13) and (14) by using the new broadcasting method. In addition, we prove that our scheme has the properties of t-wise forward secrecy and t-wise backward secrecy, and extend this self-healing approach to the session key recovery scheme from a single broadcast message.
