This study was carried out to investigate the intake patterns of health food according to the kind of disease of the elderly aged over 60 years living in the Chuncheon area. This study was conducted by using a questionnaire from December 1999 to the March 2000. The data was analyzed using a SPSS program. The results were summarized as follows : The poorer the self- perceived health condition, the lower the level of activity of daily living(ADL) and instrumental activities of daily living(IADL) were the higher. the frequency score of health food intake. The incidence of disease, such as arthritis(44.7%), hypertension(18.8%), digestive diseases(17.1%), diabetes(10.5%) were found to be higher. than other chronic diseases among the elderly. The frequency score of health food intake was not significantly different according to self-perceived health status, disease status, or the level of ADL and IADl.. The must important source of information for health food intake was the recommendation of friends and relatives(68.7%). Twenty eight point two percent of the elderly considered health foods to be effective, however 8.3% of the elderly considered them to be ineffective. The elderly with chronic diseases had taken health floods in the descending order of neuralgia-arthritis, hypertension, digestive disease, diabetes. The elderly with digestive diseases, diabetes, renal disease, neuralgia- arthritis and respiratory disease were inclined to habitually take health floods once or twice per year. Intake of Korean traditional folk food was as high as intake of registered health food and Chinese tonic medicine. The most frequently taken health food was tonic medicine, which is fo11owed by pumpkin, ginseng products, herbal tea formula with black goat, deer antler and Kye-so-ju. Intakes of health food such as tonic medicine, blood of the deer, royal jelly, aloe were found to be higher among the elderly with chronic diseases such as diabetes, hypertension, and digestive disease. However, intakes of ginseng products, deer antler, pumpkin, herbal tea formula with black goat and Kye-so-ju were found to be higher among the healthy elderly. The elderly with neuralgia-arthritis had taken sixteen kinds of health foods. From these results, a wide consumer education program should be developed to convince people of the importance of well-balanced diet and to choose proper health foods according to the elderly's health conditions. Also, comprehensive and scientific research into Korean traditional folk foods are needed for the correct use.

The purpose of the study was to test the reliability and validity of the Korean version of Task Self-Efficacy Scale for activities of dally living (ADL). The Task Self-Efficacy Scale was developed by Roberts(1996) for low-intensity exercise study with older people to predict their performance of ADL. The scale was translated and back translated by bilingual persons, and then was modified to resolve variations in the translations. The Korean version of Self-Efficacy Scale for ADL was then administered to 193 elderly people including 95 hospitalized patients and 98 outpatients or healthy people. Face to face interview was used to fill out the structured questionnaire, and each interview took approximately 30 minutes. The subjects for the study were 80 women and 112 men with an age range of 65 to 95 years(M=71 years) of whom 82.6% classified themselves as moderate or quite active Most subjects(80.2%) had an education level of elementary school or less. The Self-Efficacy Scale for ADL is measured on a 0 to 10 VAS, assessing three areas of ADL : self care activities, household tasks, and motor tasks. The higher the score is, the higher person's confidence in performing ADL. Psychometric testing revealed that the scale was found to be internally consistent, showing a Cronbach's alpha of .97 The scale was significantly correlated with subjects' level of activity and subjective assessment of their health status. Moderate correlation with health-related hardiness scale also supported the validity. Factor analysis was performed to confirm whether the scale represents the three sub-areas as suggested in the literature. The results of the factor analysis led to a three factor solution according to Kaiser's criterion, but the items were not strongly and cleanly loaded for the third factor. This can be explained in that, among the three sub-ADL areas of the self-efficacy scale, the areas of self care activities and household tasks seem to have similar levels of difficulty in performance with not enough differences for the self-efficacy scale to distinguish between the two areas. Therefore, one factor solution was suggested since ADL can be seen as a unit of activities at similar level of difficulty in performance. One factor solution explained 68.1% of variance of the 19-item scale and all items were correlated over .6 with the factor, showing that the selected factor solution fits the model. The results indicated that the Korean version of Task Self-Efficacy Scale for ADL was reliable and valid in producing useful information to evaluate the effects of various interventions toward promoting health and quality of life for elderly people.

Background: Bedridden patients and disabled persons need help from a guardian or caregiver even in performing simple activities of daily living. In particular, for body transfer of them, the use of a transfer lift has been recommended. However, the devices currently in use have limitations in terms of support according to the individual's characteristics. This study aimed to develop a transfer lift device utilizing the patients' body-fitting sling equipped with an air tube inside the sling. In addition, we have conducted usability tests to examine the safety, effectiveness, and satisfaction with this device. Design: This study conducted usability tests with 10 healthy adults. Methods: Customized sling lifts are generally floor-based devices that consisted of a sling that holds the patient's body and a lift that moves the sling to the desired position. One characteristic feature of the device is an air tube, which is used on the sling to allow the patient's body can be adjusted. A usability test was performed in terms of the operators, who operated the device to transfer the patients. Ten operators tried the device and tested its usability. Results: The mean of 10 question for Questions was 4.18. Conclusion: The device can be useful in the advance- ment and commercialization of customized sling lifts, to ensure the safe and efficient transfer of persons with disabilities.

Background: Squatting is one of the best functional exercises to strengthen the quadriceps muscle in independent gait and activities of daily living. Although the use of a gym ball during squat exercise is the most common way of strengthening the vastus medialis oblique (VMO) muscle, published data on this subject are limited. Objects: The purpose of this study was to compare the sequential muscle activation of the VMO and vastus lateralis (VL) muscles during squat exercise using a gym ball at different knee flexion angles. Methods: Forty healthy adults were randomly divided into experimental (squat exercise using a gym ball) and control (squat exercise alone) groups, in which squats were performed at $45^{\circ}$ and $90^{\circ}$ knee flexion. Electromyographic (EMG) activity data were collected over 10 seconds under the 2 angles of knee flexion ($45^{\circ}$ and $90^{\circ}$). Results: There was significant group and time interaction effect for VMO and VL muscle activation at $45^{\circ}$ knee flexion. This was similarly demonstrated at $90^{\circ}$ knee flexion. No significant group main effect and time main effect for VMO and VL muscle activation were noted at $45^{\circ}$ knee flexion, respectively. In contrast, there was significant group main effect and time main effect for VMO and VL muscle activation at $90^{\circ}$ knee flexion. These significant differences were demonstrated through two-way analysis of variance over repeated measurements, suggesting that the EMG activity of the VMO muscle during squatting with a gym ball showed remarkable improvement compared to that of the VL muscle. Conclusion: This research suggests that squat exercise using a gym ball may be more beneficial in improving the activity of VMO than of the VL muscle at both $45^{\circ}$ and $90^{\circ}$ of knee flexion, respectively. We highly recommend squat exercises with a gym ball for selective strengthening of the VMO muscle in knee rehabilitation.

Purpose : The study investigated the effects of Pilates exercise on strengthening trunk muscles of females who perform such exercise for the purpose of comparing activation of trunk muscles that contact while performing Pilates motions between females with or without at least 8 weeks of Pilates experience. Methods : The study investigated 10 females with at least 8 weeks of Pilates experience in the past 6 months (experienced group) and 10 healthy females without Pilates experience (non-experienced group). The study used basic Pilates postures involving hip abduction, lift, and leg swing motions as the measurement postures in comparing the activation of muscles used for stabilization, such as the rectus abdominis, external oblique abdominal, and transverse abdominis & internal oblique abdominal muscles. Surface electromyography was used for measuring muscle activation, and the measurements targeted activation of the rectus abdominis, external oblique abdominal, transversus abdominis, and internal oblique abdominal muscles. Results : The study results showed that, as compared to the non-experienced group, the experienced group had significantly higher muscle activation in the transverse abdominis and internal oblique abdominal muscles during hip abduction (p<.05) and significantly higher muscle activation in the rectus abdominis, external oblique abdominal, and transverse abdominis & internal oblique abdominal muscles during lift and leg swing motions (p<.05). Conclusion : Pilates exercise performed over a long period can be recommended as an effective exercise method that can increase the activation of trunk muscle, and especially, repeated performance of highly difficult motions can increase muscle activation even more, which can help promote spinal stabilization, prevent pain, and improve performance of activities of daily living.

Falling is one of the major public problems to the elderly, resulting in limitations of daily living activities. It can be induced by the functional loss of the balance ability and muscle strength in the elderly. It has been, however, not well investigated to suggest an effective methodology improving the balance ability and muscle strength for the prevention of the falling due to lack of information about the characteristics of the balance and muscle activations responded to the dynamic motions. The aim of the current study is, therefore, to identify the characteristics of the balance and muscle activations responded to the dynamic motions in Anterior-Posterior(AP) and Medial Lateral(ML) directions. For that, a motion capture system with eight infrared cameras, surface electromyogram system and Wii Fit system with a customized variable unstable base were used and kinematic and kinetic data obtained from the systems were analyzed for five healthy male($24.8{\pm}3.3years$, $177.4{\pm}2.0cm$, $73.9{\pm}12.9kg$, $23.5{\pm}4.0kg/m$). The results showed that the characteristics of the balance and muscle activations were differently responded to between the dynamic motions in Anterior-Posterior(AP) and Medial Lateral(ML) directions. These findings may indicate that customized dynamic motions should be applied to the training of the balance ability and muscle strength for the effective prevention of the falling. This study may be meaningful to providing basic information to establish a guideline improving effectively the balance ability and muscle strength.

This study examines the effects of coping resources on life satisfaction of middle and older caregivers looking after family members with activities of daily living disabilities. Personal resources and socio-relational resources were included as predictors after controlling for demographic characteristics. We studied 154 middle and 132 older adults drawn from the Korean Longitudinal Study of Ageing (KLoSA). The multiple regression results of this study were as follows. First, subjective health and family satisfaction had significant effects on middle-aged caregivers' life satisfaction. Specifically higher levels of subjective health and better relationships with their family predicted higher levels of life satisfaction. Second, cognitive function, household income, and family satisfaction had significant effects on middle-aged caregivers' life satisfaction. Higher household incomes, higher levels of cognitive function, and better relationships with family predicted higher levels of life satisfaction. For both middle and older adults, the effect size of family satisfaction was the largest out of all coping resources. The results revealed discrepancies regarding the importance of coping resources between middle and older caregivers, implying that developing interventions for middle and older caregivers (in accordance with their need for coping resources) is necessary. The results also indicated that having good relationships with one's family was the most important factor for both middle aged and older caregivers' life satisfaction. The results suggest that policies or services focused on endorsing healthy family relationships should be developed to improve the life satisfaction of caregivers.
