As the population of elderly in Korea is increasing rapidly since the 1990's and will more rapidly in the 21st Century, the demand of their health care would be a great burden to health care expenditure. Then it would be necessary to contemplate the functional status and life satisfaction for elderly to make them live more independently. The objectives of this study were find out the functional status in life and life satisfaction for the elderly aged 65 or over who had resided in urban area of two Gus in Pusan and rural area of two Myuns in Haman Gun in Kyeognam Province, and to provide basic data for planning systematic health care programme. The study period was two weeks from February 6 to February 18, 1995 and the subjects were 274 elderly of which 143 were urban residents, 131 were rural residents, and the study method was by structured questionnaire. The data were analyzed with SAS/PC/sup +/ programme using Chi-square test, t-test, ANOVA, Pearson's correlation coefficients, and multiple regression analysis. The results were as follows; 1. To see the pattern of living together, those living with partners were the most common, 39.1% ; 37.8% of urban elderly lived with married sons, 32.2% of them lived with partners, but 46.6% of rural elderly lived with partners, 16.8% of them lived with married sons, which showed difference between residence(p<0.005). 2. Elderly who had jobs were 64.1% in rural residents, and 7.7% in urban residents, which showed significant difference(p<0.05). 3. The score of cognitive function of total subjects was 24.7, that of urban elderly was 23.8, and that of rural elderly was 25.7, then it was higher in rural ones and low for old-elders and those who had no jobs. 4. The score of PADL was 26.8 for urban elderly, 30.1 for rural elderly, and that of IADL was 22.2 for urban elderly, 25.6 for rural elderly, which showed higher activities of daily living for rural elderly than urban elderly(p<0.001). 5. The score of domestic performance was 21.9 for urban elderly, and 30.5 for rural elderly, which showed higher score for rural elderly(p<0.001). 6. The score of life satisfaction was 20.7 for urban elderly, 29.8 for rural elderly, then it was higher for rural elderly(p<0.01). 7. As a result of ANOVA for functional status in living by general characteristics; the score of cognitive function differed by age, job; that of PADL differed by age, job, education, and the pattern of living together, that of IADL differed by age, job, and the pattern of living together. The score of domestic role performance differed by age, job, marital status, and the pattern of living together. 8. ANOVA for life satisfaction showed that the score of life satisfaction differed by job(p<0.001) and the pattern of living together(p<0.01). 9. The correlations between functional status in living and life satisfaction showed that the higher the score of cognitive function was(r=0.39), the higher the score of activities of daily living was(r=0.50), and the higher the score of domestic role performance was(r=0.41), the higher the score of life satisfaction. 10. Stepwise multiple regression analysis for life satisfaction pointed out that residence was responsible for 39.9% of the variance. cognitive function was for 5.3%, and domestic role performance was for 1.2%.

The aim of this study is to investigate the usefulness of the multiple-choice name matching test (MC-NMT) in adults with aphasia by comparing the Korean version of the Boston Naming Test (K-BNT) and subsets of the Korean version of the Western Aphasia Battery (K-WAB). Thirty-nine patients who suffer from aphasia participated in the study. All patients were examined by the K-BNT, MC-NMT and K-WAB. The MC-NMT consisted of the 30 original BNT object stimuli which were presented with four response choices (written words) with similar frequency, including one correct and three incorrect responses. Cards containing the drawings were presented to the patient one at time. An item was passed if the patient chose the correct response within 10 seconds. We subdivided two groups into a total group and a low K-BNT group (at and below 15 points). We evaluated the correlation between the K-BNT, MC-NMT score and production, naming, repetition, comprehension, reading and writing scores in subsets of the K-WAB. There was a highly positive correlation between the K-BNT score and naming score of the K-WAB in total patients. However, the MC-NMT was highly correlated with reading scores in the K-WAB. In low score K-BNT patients, the K-BNT strongly correlated with production, naming and repetition scores of the K-WAB. These findings mean that K-BNT reflects motor language function. However, the MC-NMT was strong correlated comprehension, reading and writing of the K-WAB. This finding reflects sensory language function. We suggest that the combination of K-BNT and newly developed MC-NMT will be useful to evaluate speech functions in aphasic patients.

Purpose: The purpose of this study was to investigate the effect of electroacupuncture on NeuN expression in ventral horn motor neurons of spinal cord, changes in pain thresholdchanges in motor function in rats with partially dissected sciatic nerves. Method: A total of 120 male Sprague-Dawley rats were randomly divided into two groups, a control group and a group administered electroacupuncture at ST36, LI11 and SP9 with 120 Hz and 0.5 mA. Animals were sacrificed on days 1, 3, 7, 14 and 28 after nerve injury (the sciatic nerve was partially dissected). The pain threshold was recorded by an Analgesia? meter and a BBB? score was calculated for motor function. After preparing lumbar spinal cord slide sections, they were immunostained with NeuN antisera (1:2,500). Results: The numbers of NeuN immunoreactive neuronsin the electroacupuncture group was increased compared to the control group. The numbers of NeuN immunoreactive neurons on days 14 and 28 day were different (p<0.05), as were the numbers on days 3 and 7 (p<0.01). The pain threshold BBB score for the electroacupuncture group was higher than for controls. Conclusion: The increase in pain threshold, BBB-score and number of NeuN immunoreactive neurons inventral horn motor neurons of spinal cord in rats withnerve dissection showed that electroacupuncture can attenuate pain transduction and increase motor function. Also, NeuN was a good marker for identifying the degree of nerve cell loss after nervous system injury.

This study shows decision-making process for selection of cutoff wall on a wastewater treatment project. There are 10 different cut-off wall methods So, we examine the site to gather information for find appropriate methods. After using that information, 10 cutoff wall methods are reviewed for analysis. Through brainstorming, four alternatives are selected for design VE item. Following the standard VE process, we established performance criteria and evaluated function score(F) using questionnaire. The questionnaires, brainstorming and AHP method for weighting on performance criteria and evaluate function score increased the reliability of this selection process. Water Jet method, one of four methods, has the best function score(F=92.71) and the lease construction cost(as cost index 1,000). The value score also highest as 92.7, so we select the method. The result is value innovation type In addition, the authors try to calculate the environmental burden in selection process using LCA. We cannot conduct the full LCA as defined ISO, so perform Simple LCA In LCA result, the cut-off grouting has the least environmental burden as index 9.09E+01 and Water Jet method has following as the second. To selection best method to specific area and purpose, design VE/LCG process used as useful tool and it is needed to develop integrated method that evaluate VEILCC and LCA as one-set process.

Recently, we aim to improve the quality of virtual reality contents based on quantitative analysis results of emotions through combination of emotional recognition field and virtual reality field. Emotions are analyzed based on the participant's vital signs. Much research has been done in terms of signal analysis, but the methodology for quantifying emotions has not been fully discussed. In this paper, we propose a normalization function design and expression method to quantify the emotion between various bio - signals. Use the Brute force algorithm to find the optimal parameters of the normalization function and improve the confidence score of the parameters found using the true and false scores defined in this paper. As a result, it is possible to automate the parameter determination of the bio-signal normalization function depending on the experience, and the emotion can be analyzed quantitatively based on this.

This study was done to explore the effects of dance therapy on pulmonary and cognitive functions in the elderly. The design of this study was a non-equivalent pre-post test experiment. The subjects consisted of elderly persons living in a facility located in Kyoungi-Do. Fifty eight subjects had normal cognition, sensory function and resting blood pressure. They underwent tests of pulmonary and cognitive function as baseline data before dance therapy, and at 6th week and at the end of 12nd week after following dance therapy. Twenty seven elderly persons were assigned to the experimental group and participated with the dance therapy. This therapy was based on the Marian Chace's dance therapy and Korean traditional dance with music. The dance therapy consisted of 50 minutes session, 3 times a week for 12 weeks. One session consisted of warming-up, expression, catharsis, sharing and closing stage. the intensity of the dance therapy was at the 40% of age-adjusted maximum heart rates. Data were analyzed with mean, standard deviation, Chi-square test, unpaired t-test, repeated measures ANOVA, and Bonferroni multiple regression using SAS program. The results were as follows : 1. Pulmonary function(forced expiratory volume at one second and forced vital capacity) of the experimental subjects significantly increased over time more than that of the control subjects. 2. The experimental group had significantly higher score for pulmonary function than the control group at the 12nd week after dance therapy. 3. Cognitive function of the experimental subjects significantly increased over time more than that of the control subjects. 4. The experimental group had significantly higher score for cognitive function than the control group at the 6th week and 12nd week after dance therapy. The findings showed the dance therapy could be effective in improving the pulmonary and cognitive function of the elderly.

This study presents a comparative analysis on mackerel distribution process and price formation process, and investigation of price and margin between traditional markets and Large-scale discount store distribution channel. Through this, the study investigated distribution efficiency of each channel, and examined whether a difference of distribution efficiency leads to a difference of performance through the investigation of a difference of function and role between members of a wholesale market and vendor of Large scale discount store. The following are the results of this study. As a consequence of investigating supply and sum by distribution channel of mackerel, it appeared that mackerels shipped from port market are distributed into 9 consumption sites(Wholesale market, Large scale discount store, Institutional Food Service, etc.). In the comparison of distribution efficiency between traditional retail store and Large scale discount store 52.0% margin is formed in traditional retail store distribution channel and 43.1% margin is formed in Large scale discount store, and a distribution cost rate consists of 19.4% cost in a traditional retail store for fishery products and 18.1% cost in a Large-scale discount store. To analyze a difference of performance, the study examine a difference of role and function between vendor and Wholesale market company, wholesaler and middleman. Wholesale market company and middleman of wholesale market for consumer have slightly high or similar score in collection function, sorting function, evaluation function and financial function which are traditional and original. However, it was confirmed that vendor has a better score in other functions, that is, newly-demanded functions(ex : market frontier function, product development function, Integral Distribution Function, etc.).

Background: Knee osteoarthritis (OA) diagnosis using Kellgren-Lawrence scores is commonly used to help decision-making during assessment of the severity of OA with assessment of pain, function and muscle strength. The association between Kellgren-Lawrence scores and functional/clinical outcomes remains controversial in patients with knee OA. Objects: The purpose of this study was to examine the relationships between Kellgren-Lawrence scores and knee pain associated with OA, function during daily living and sports activities, quality of life, and knee muscle strength in patients with knee OA. Methods: We recruited 66 patients with tibiofemoral knee OA and determined knee joint Kellgren-Lawrence scores using standing anteroposterior radiographs. Self-reported knee pain, daily living function, sports/recreation function, and quality of life were measured using the knee injury and OA outcome score (KOOS). Knee extensors and flexors were assessed using a handheld dynamometer. We performed Spearman's rank correlation analyses to evaluate the relationships between Kellgren-Lawrence and KOOS scores or muscle strength. Results: Kellgren-Lawrence scores were significantly negatively correlated with KOOS scores for knee pain, daily living function, sports/recreation function, and quality of life. Statistically significant negative correlations were found between Kellgren-Lawrence scores and knee extensor strength but not flexor strength. Conclusion: Higher Kellgren-Lawrence scores were associated with more severe knee pain and lower levels of function in daily living and sports/recreation, quality of life, and knee extensor strength in patients with knee OA. Therefore, we conclude that knee OA assessment via self-reported KOOS and knee extensor strength may be a cost-effective alternative to radiological exams.

Purpose : The purpose of this study was to examine the effects of a virtual reality-based complex cognitive training program for depression, cognitive function, and digital divide reduction in the elderly who have not been diagnosed with dementia or MCI. Methods : We enrolled 16 participants who were over 65 years old and not been diagnosed with dementia or MCI. We randomly divided into three groups (A, B, C). Participants underwent an 8-week virtual reality-based complex cognitive training program (60 minutes each session, twice per week). At a baseline, all participants completed questionnaires on general features, depression and cognitive function. After four weeks, all participants completed questionnaires on depression and cognitive function. After the end of the last program, participants conducted questionnaires on depression, cognitive function, and usability evaluation. Results : At the 8-week follow-up, 16 participants completed the program. Compared to the baseline, the average score of cognitive function was increased (from 26.5 to 28.5), although it was not statistically significant (p<.061). There were no significant differences between baseline and post-training evaluations on depression scores. The average score of usability evaluation was 75.56, which corresponds to good. Conclusion : Even though the results showed no statistically significant findings in cognitive function and depression after the virtual reality-based complex cognitive training intervention, this pilot study proposed the possibility of utilizing the virtual reality program as a tool that provides active learning opportunities for the elderly and helps improve their cognitive function through multi-sensory components. Also, the findings of this study suggested a positive reevaluation of the elderly's digital access capabilities while reducing the digital divide. A virtual reality-based complex cognitive training program improved the social network of the elderly. We expect that it will expand in size and help with their social participation of the elderly.
