The purpose of this study is to analyze the effect of social participation types on cognitive impairment degree(normal, mild, severe cognitive function) by urban and rural difference. The research was performed by multinomial logistic regression with the data of elderly 5,668 over 55 years of age from the sixth wave(2016) and the seventh wave(2018) of the Korean Longitudinal Study of Ageing. Results show that social participation reduces the risk of cognitive impairment on both urban and rural older adults regardless of types, but the types of social participation, which are effective to reduce the risk of cognitive impairment, are different between urban and rural area. According to residential area, types of social participation, which are effective to decline the risk of being mild or severe cognitive impairment and the risk of being severe cognitive impairment relative to mild, are different. These findings suggest that, in order to prevent cognitive impairment and reduce the severity, social participation is strongly recommended and appropriate supports are required. This implies policy and intervention efforts considering the urban and rural difference are needed.

This study uses [the instrument of ageing anxiety] in order to find if a negative prejudice against the old affects the attitude toward sex of the aged. The result shows no significant relation between ageing anxiety and the knowledge of and attitude toward sex of the aged. However, it does show that the higher the ageing anxiety is, the lower the knowledge of sex and the more restrictive the attitude toward it. The knowledge of and attitude toward sex of the aged shows meaninggul changes after education. Nursing students who were educated come to have more knowledge about and are more open to it. This result supports the preposition of this study. As society grows older the endeavour to guarantee a high-quality life for the old is necessary and the old should be regarded as an entity which has its own characteristic desires. Especially for the old to enjoy a good life as a sexual being, the mystical barriers about sex and old age ought to be removed. In the future the old themselves may maintain sexual desires regardless of age and society will be required to correct its prejudice against the old having sex. Particularly nursing students, as an effort to provide the old with overall care, should examine the elderly's sexual desires in a physical, psychological, and social context and consider the normal sexual changes occuring during the aging process and finally integrate this information into their nursing plans. In order to fulfill this role successfully they should overcome their own prejudice and educate themselves about this particular problem. As the proportion of the old becomes bigger and the concern about the quality of their life grows, sex among the old will become more important in the nursing field. By putting an educational mediation programme into operation with nursing students and estimating the effect, this study supplies the foundation to activate new educational programmes. In short it tells us that education can be a practical method to confront the myth and conventions concerning sex among the aged.

This study investigated the navigation ability of patients with MCI in Virtual Environments(VE) and on the visual functioning. The participants consisted of elderly adults with/without MCI. Neuropsychological tests(RCFT, BVRT, TMT, and Digit Span), the Groton Maze Learning Test(12trials), and the VE navigation learning task(6 trials) were performed. As a result, there were significant group differences for the RCFT and BVRT, but not for the GMLT. For the VE task, there was a significant difference between the MCI and normal group and no interactions between the groups and trials were found. The VE task was correlated with The RCFT, the BVRT, and the GMLT and omnibus the RCFT and the BVRT accounted for 45% of VE performances. Thus, we concluded that patients with MCI are inferior to VE navigation and visual retention/memory play a role in navigation abilities.

Recently, technologies to help the elderly or disabled people who have difficulty in walking are being developed. In order to develop these technologies, it is necessary to construct a system that gathers the gait data of people and analysis of these data is also important. In this research, we constructed the development of sensor system which consists of pressure sensor, three-axis accelerometer and two-axis gyro sensor. We used k-means clustering algorithm to classify the data for characterization, and then calculated the symmetry index with histogram which was produced from each cluster. We collected gait data from sensors attached on two subjects. The experiment was conducted for two kinds of gait status. One is walking with normal gait; the other is walking with abnormal gait (abnormal gait means that the subject walks by dragging the right leg intentionally). With the result from the analysis of acceleration component, we were able to confirm that the analysis technique of this data could be used to determine gait symmetry. In addition, by adding gyro components in the analysis, we could find that the symmetry index was appropriate to express symmetry better.

Like Alzheimer's disease, Parkinson's Disease(PD) is one of the most common neurodegenerative brain disorders. PD results from the deterioration of dopaminergic neurons in the brain region called the substantia nigra. Currently there is no cure for PD, but diagnosing in its early stage is important to provide treatments for relieving the symptoms and maintaining quality of life. Unlike many diagnosis methods of PD which use a single biomarker, we developed a diagnosis method that uses both biochemical biomarkers and imaging biomarkers. Our method uses ${\alpha}$-synuclein protein levels in the cerebrospinal fluid and diffusion tensor images(DTI). It achieved an accuracy over 91.3% in the 10-fold cross validation, and the best accuracy of 72% in an independent testing, which suggests a possibility for early detection of PD. We also analyzed the characteristics of the brain fiber pathways of Parkinson's disease patients and normal elderly people.

Background and Objectives: Tinnitus is on the increase due to the increase in the elderly population, industrial pollution and noise pollution. This symptom is especially marked in patients with a hearing problem and the relationship between cause, mechanism and treatment is poorly understood. The characteristics of tinnitus and other hearing problems are well brought out using an animal model with salicylate ototoxicity. Therapeutic effects of Uncariae Ramulis and Testudinis Plastrum were expected in tinnitus and hearing problems; therefore we experimented on an animal model with salicylate ototoxicity. Salicylate is one of the most commonly prescribed drugs, although it has been recognized that salicylate induces hearing loss and tinnitus reversibly. The purpose of this study was to find the therapeutic effects of this by the morphologic study using salicylate ototoxicity. Materials and Methods : Twelve healthy Sprague-Dawley rats were divided into three groups: normal, control and sample. The sample group was treated with the extract of Uncariae Ramulis and Testudinis Plastrum (1cc/100g, once a day for 6 days). Then, to induce the salicylate ototoxicity in the control and sample groups, rats were injected intraperitoneally with sodium salicylate (500mg/kg). We observed the morphologic changes in the cochlea of the rats every 2, 3, 4 and 5 hours after injection. Results : The outer hair cells showed marked changes. Vacuolization formed in the cuticular plate and the endoplasm of the control group. The endoplasm and the cuticular plates of the sample group after 2 hours were similar to the control group, but the cuticular plates of the sample group observed after 3, 4 and 5 hours were not similar. Conclusions : The results suggest that an extract of Uncariae Ramulis and Testudinis Plastrum has therapeutic effects on an animal model with salicylate ototoxicity.

Hypothyroidism is a common disease of the endocrinal system, characterized by fatigue, cold intolerance, bradycardia, and so on. Subclinical hypothyroidism is a common biochemical abnormality which can be found in routine screening tests of thyroid function. It is defined as an asymptomatic state which characterized by normal free thyroxine(FT4) and elevated thyroid stimulating hormone(TSH) levels. The purpose of this study was to evaluate the effect of treatment with palmijihwang-tang and to observe the changes in triiodothyronine(T3), free thyroxine(FT4), thyroid stimulating hormone(TSH) level and VAS of cold intolerance, hoarseness, dry skin. After the treatment, triiodothyronine(T3) increased from 57.12ng/dl to 120.53ng/dl. Free thyroxine(FT4) increased from 12.59pg/ml to 14.21pg/ml. Thyroid stimulating hormone(TSH) decreased from 10.61mU/L to 1.57mU/L. Cold intolerance, hoarseness and dry skin changed for the better. These results support a role for oriental medical therapy in treating subclinical hypothyroidism. Further case studies of herbal treatment of this ailment are needed.

It is already known that olfactory susceptibility differ with races and sex. Moreover, with aging both detection and identification about olfactory information were impaired. For researches about evaluation of the odor with aging, although the subject used, from infants to elderly, was various, the kinds of odor used were restricted to simple alcohol and acetic acid. Also, the evaluation methods were mainly used olfactory test. From over respects , this research was done as follows. Subjects were 19 to 72 years (n=50) whose sense-of-smell functions are normal. They were taken as stability and closed eye state. The odor stimuli were used 100% natural odor of six kinds of Basil, Lavender, Lemon, Jasmine, Ylangylang oil and Skatole , during 60 seconds using olfactometer. ECG, GSR and subjective evaluation were measured, and examined their relevance. Twenty and 40 ages group evaluated Lemon and 60 ages group did Lavender affirmatively. Correlation was seen among RRI, HR, GSR and subjective evaluation for 40 ages group, and it turns out that it is the group which a mature olfactory function most. These results are fully applied not only to development of the classified cosmetics for the age group but to development of the artificial smell and taste.

The purpose of the current experiment was to describe interlimb coordination when swing limb conditions are being manipulated by constraining step length or by adding a 5 or 10 pound weight to the swing limb distally. Subjects were asked to begin walking with the right limb to land on the primary target (normal step length) that is 10 cm in diameter. However, if, during movement, the light was illuminated, then the subject had to step on one of the secondary targets (long and short step length). These three step length conditions were repeated while wearing a 5 pound ankle weight and then when wearing a 10 pound ankle weight. Ground reaction force (GRF) data indicated that there were changes in the forces and slopes of the swing and stance Fx GRFs. Long stepping subjects had to increase the propulsive force required to increase step length. Consequently, swing and stance toe-off greatly increased in the long step length condition. Short step length subjects had to adequately adjust step length, which decreased the speed of gait initiation. Loading the swing limb decreased the force and slope of the swing limb. Swing and stance toe-off was longest for the long step length condition, but there was a small difference of temporal events between no weight and weight condition. It appears that subjects modulated GRFs and temporal events differently to achieve the peak acceleration force of the swing and stance limb in response to different tasks. The findings from the current study provide preliminary data, which can be used to further investigate how we modulate forces during voluntary movement from a quiet stance. This information may be important if we are to use this or a similar task to evaluate gait patterns of the elderly and patient populations.
