The study was designed to heap reduce daily household waste and promote the recycling of society's resources. the focus is on promoting environment-friendly activities and slevating a sense of nature-conscious domestic welfare, as well as providing wars to encourage garbage-savvy shopping, waste disposal by content and recycling. The thesis utilized demographic data obtained from 225 female homemakers and includes results based on frequency, ratio, mean, Duncan's Multiple range Test and Multiple Regression analysis. The main results are as follows: 1. Environmental consciousness appears to be higher than that of the adjustment of purchases to reduce waste and of recycling. Conversely more action seems to be taken on the waste disposal separation established since the launch of the volume-based waste collection fee system than on environmental education. 2. Homemakers with relatively higher environmental consciousness reciprocate with correspondent shopping habits, waste disposal eparation and recycling. Factors that influence daily waste reducing action include environmental consciousness homemaker employment status and the type of residence. 3. Activities reducing daily domestic wastes appear to effect a meaningful variable in explaining a sense of environmental welfare. The more respondents practice related shopping habits, waste disposal separation or recycling the more they recognize their living environment as desirable.

This study was conducted to examine the influence and effect of muscle enforcement program on Activity of daily living(ADL) improvement and posture balance of the old, and to provide more effective muscle enforcement program and educational data. The muscle enforcement exercise program was performed on the old(institution, 16 men, 10 women) for 8 weeks from April 22, 2002 through June 17,2002. Programed Exercise 1 - Exercise 10 were practised 8 times per program for 3 days a week. The load of exercise was increased per two weeks. The methods of measurement were questionnaire, Indiana 47903(action-response analysis machine) and Sample exercise protocol for KAT 2000(balance training device). SAS/PC statistic analysis was used for data analysis. T-test was used for analysis of change before and after exercise in this study. The summary and conclusions are as follows. 1. On subjectively recognized health states, the healthy were $42.3\%$. On the satisfaction with health states, the satisfied were $50.0\%$. On the factors of effects on daily-life behavior performance, the group who had troubles was $50\%$ and the group who was so and so was $34.6\%$ compared with the old of the same age. On prospect about health states in the future, the group who would be better was $38.\%$. On effective methods for problem solving, exercise was $42.3\%.\;88.5\%$ of respondents answered the need of health care. The participation intention in health program was $92.3\%$. 2. On the change of psychological emotion and behavior aspects, the group who had repeated complaints or anxieties and reduced activities or interests was effective(P<0.01). 3. On the improvement effects of IADL difficulties, the group who had difficulties in doing daily-life indoors was improved effectively compared with before and after exercise(P<0.01). On medication management, the effects of improvement after exercise were high compared with before exercise(P<0.01), the effects of improvement was high on the whole. 4. On the effects of ADL function improvement, putting on upper clothing and lower clothing was improved effectively(P<0.05), toilet use and individual sanitation was improved effectively(P<0.05). 5. On the effects of action-response, the results of 8weeks regular exercise program were not different significantly compared with before and after exercise. The behavior quickness of the old by muscle enforcement program was not increased. This means that the old needs much time for exercise sense training because of the regression of cognition sense. 6. In the effect of posture balance, the whole grades were effective from 1272.69 before excercise to 476.92 after exercise(P<0.01). Especially right balance 657.65 was lowered to 208.57 after exercise most effectively(P<0.01). Rear balance 776.34 before exercise was lowered to 136.65 after exercise. The results of measurement were significant(P<0.05).

Over the last few years, one of the most common purposes of smart homes is to provide human centric services in the domain of u-healthcare by analyzing inhabitants' daily living. Currently, the major challenges in activity recognition include the reliability of prediction of each classifier as they differ according to smart homes characteristics. Smart homes indicate variation in terms of performed activities, deployed sensors, environment settings, and inhabitants' characteristics. It is not possible that one classifier always performs better than all the other classifiers for every possible situation. This observation has motivated towards combining multiple classifiers to take advantage of their complementary performance for high accuracy. Therefore, in this paper, a method for activity recognition is proposed by optimizing the output of multiple classifiers with Genetic Algorithm (GA). Our proposed method combines the measurement level output of different classifiers for each activity class to make up the ensemble. For the evaluation of the proposed method, experiments are performed on three real datasets from CASAS smart home. The results show that our method systematically outperforms single classifier and traditional multiclass models. The significant improvement is achieved from 0.82 to 0.90 in the F-measures of recognized activities as compare to existing methods.

Background: Evaluation of the effectiveness of caudal epidural injection on pain, spine mobility, disease activity, and activity of daily living in axial spondyloarthritis (SpA) patients. Methods: A total sample of 47 patients were registered in this study. They were randomly assigned into 2 groups; Group I received caudal epidural injections, ultrasound-guided, with 1% lidocaine hydrochloride mixed with triamcinolone, whereas Group II did not receive any injections. All participants fulfilled the ASAS criteria for axial SpA. Outcome measures were as follows: visual analogue scale, Oswestry disability index (ODI), modified Schober test, lateral lumbar flexion, and Ankylosing Spondylitis Disease Activity Score (ASDAS) with assessment at baseline, 2 weeks, and 8 weeks post-treatment. This clinical trial was registered on clinicaltrials.gov under the number NCT04143165. Results: There was a significant difference between both groups regarding pain, ODI, spine mobility and ASDAS scores in favor of group I. This effect was at its maximum after 2 weeks. Despite the decline of this effect after 2 months, the difference between the groups remained significant. Higher disease activity, younger age, and shorter disease duration were associated with better outcomes. Conclusions: Epidural injection of lidocaine and triamcinolone is a cost effective and a practical technique for controlling pain, as well as improving the function of the spine and disease activity scores in axial SpA patients with acceptable complications and relatively sustained effect.

Stroke is one of the leading causes of long-term disability worldwide, placing huge burdens on individuals and society. Further, automatic human activity recognition is a challenging task that is vital to the future of healthcare and physical therapy. Using a baseline long short-term memory recurrent neural network, this study provides a novel dataset of stretching, upward stretching, flinging motions, hand-to-mouth movements, swiping gestures, and pouring motions for improved model training and testing of stroke-affected patients. A MATLAB application is used to output textual and audible prediction results. A wearable sensor with a triaxial accelerometer is used to collect preprocessed real-time data. The model is trained with features extracted from the actual patient to recognize new actions, and the recognition accuracy provided by multiple datasets is compared based on the same baseline model. When training and testing using the new dataset, the baseline model shows recognition accuracy that is 11% higher than the Activity Daily Living dataset, 22% higher than the Activity Recognition Single Chest-Mounted Accelerometer dataset, and 10% higher than another real-world dataset.

Purpose: This study was conducted to evaluate successful aging (SA) in elderly individuals and to determine the factors that influence SA. Methods: The subjects included 207 elderly individuals from D city, Korea. The data were obtained between July 1 and August 30, 2008. The participants were assured of anonymity and confidentiality. For the evaluation, Kim & Shin's SA scale, Lawton's instrumental activities of daily living (IADL) scale, Jon's self-esteem scale, Kee's geriatric depression scale short form-Korean (GDSSF-K), and Hong's productive activities scale were used. The data were analyzed using descriptive statistics, the t-test, analysis of variance (ANOVA), and Pearson correlation coefficients; multiple regression analysis was performed using the SPSS/WIN 10.0 program. Results: The maximum score for SA was 34, and the mean score was 22.62. It was found that SA was significantly correlated to IADL, self-esteem, depression, and productive activity. Depression was the most powerful predictor of SA and it accounted for 40.6% of the total variance in SA. Self-esteem, productive activity, living situation, economic status, and age together accounted for 62.1% of the total variation in SA. Conclusion: Depression, self-esteem, and productive activity were identified as variables that influence SA. On the basis of these results, we conclude that nurses should assist elderly individuals in order to facilitate SA. Moreover, individualized nursing management strategies must be developed in order to facilitate SA.

Objective : Questionnaires completed by occupational therapists and patients in institutions conducting a "Pilot Project of Rehabilitation Medical Institutions" were used to determine whether occupational therapy was able to establish appropriate patient support systems for return to home and community. Methods : The questionnaire was completed by 293 occupational therapists from 13 institutions conducting pilot projects and 296 patients from 8 institutions who were able to respond. Results : Although the Pilot Project of Rehabilitation Medical Institutions is being implemented to enable early return of patients to activities of daily living, the most important therapeutic goal is not efficiently applied. In addition, since the health insurance systems utilized in medical institutions are applied as in the pilot project, there is no basis for evaluation and mediation of practical daily activities and vocational rehabilitation for actual return to the community. Conclusion : Through a detailed review of the pilot project, it will be necessary to improve the quality of life through the early return of patients to social activity, and to make practical improvements to reduce unnecessary societal expenditures.

In this study, we made a survey of the degree of satisfaction and performance of daily life activities on independent elderly households in the detached house. The purpose of this study is to suggest basic data for elderly housing design to be considered elder's characteristics. A survey carried out for 110 respondents with face to face interview visiting each house between May and June, 1999 with modified and drawn questionnaire from analysis of preparatory investigation data. The questionnaire was composed of the general characteristics of respondents, general characteristics of housing, residents' satisfaction with the use of housing space, performance degree of the elder's daily activities. To analyze the data of 106 cases, frequency, percentage, mean, standard deviations, one-way ANOVA, reliability analysis and Scheffe test were used by running SPSSWIN program. The results on the housing satisfaction and performance of activities in daily life of elderly in the detached house were as follows.: In this survey, the elderly had high value in satisfaction with the size of current house as the mean 3.14 points, but they were dissatisfied with the rising of house as the mean 2.82 points. The satisfaction with living room space was the highest but the satisfaction with toilet space was lower than others. Among the activities of daily life in housing space, housing related activity was the hardest to perform as the mean of 3.15 points. In consequence, consideration on and interest in the planning of residential spaces are needed so that the elderly can perform the action of housing life effectively and efficiently.
