A competitive coevolutionary algorithm is a probabilistic search method that imitates coevolution process through evolutionary arms race. The algorithm has been used to solve adversarial problems. In the algorithms, the selection of competitors is needed to evaluate the fitness of an individual. The goal of this study is to compare and analyze several competition strategies in terms of solution quality, convergence speed, balance between competitive coevolving species, population diversity, etc. With two types of test-bed problems, game problems and solution-test problems, extensive experiments are carried out. In the game problems, sampling strategies based on fitness have a risk of providing bad solutions due to evolutionary unbalance between species. On the other hand, in the solution-test problems, evolutionary unbalance does not appear in any strategies and the strategies using information about competition results are efficient in solution quality. The experimental results indicate that the tournament competition can progress an evolutionary arms race and then is successful from the viewpoint of evolutionary computation.

PURPOSE: This study investigated the relationship between the daily physical activity level and fall-proof-related fitness in older female adults. METHODS: This study promoted and sampled the subjects who participated in the study for 2 weeks, and developed a basic information questionnaire to select the subjects to be excluded from the research. The amount of energy expenditure through daily physical activity was examined, and the elderly physical fitness, and balance test were analyzed. The subjects were divided into group A (${\geq}1,500kcal/week$), group B (<$1,500-{\geq}1,000kcal/week$), and group C (<1,000 kcal/week) according to their daily physical activity level. RESULTS: A significant difference in the daily physical activity level (energy expenditure), Chair Stand Test (lower body strength), 8-Foot Up-and Go Test (dynamic balance), and CTSIB-M (modified Clinical Test of Sensory Interaction in Balance) was observed among groups A, B, and C (p<.5), but there was no significant difference in the Chair Sit-and-Reach Test (lower body flexibility) (p>.5). CONCLUSION: The increase in physical activity is an essential factor for preventing falls and it provides many health benefits for the elderly. On the other hand, considering that elderly people cannot access exercise programs easily in Korea, it can be predicted that increasing elderly people's physical activity in daily life rather than specific exercises may help prevent falls.

The purpose of this study is to provide for the basic data useful to the effective production. For this purpose, 180 Korean mothers who bring up from newborns to four-year-old babies were sampled to survey the problems on size occurred by wearing and purchasing the Infants'Wear and positively identify the factors affecting the fitness. Data is processed by a computer(SAS) and analyzed by using frequency, perentage, mean, χ²-test, Duncan-test. The main results of this study are as follows ; 1. Consumers'awareness of sizing system of Infant's wear tent to present relatively high and tend to purchase their infants'wear larger than actual sizes or that consumers'preferences depend little on size adaptation. 2. As a result of analyzing the part not fit, neck circumference, waist circumference, total length, neck back-waist length is short, sleeve length, pants length, shoulder length is big. In all, it has been found through this study that fitness and awareness of sizing system of Infant's Wear in purchasing infants'wear was influenced by many external factors. Therefore, in order to maximize the size adaptability for infants, Infants'Wear must be present the reasonable sizes and specifications for infants'wear in consideration of domestic and foreign specifications and infants'health condition.

This study was done to investigate levels of physical fitness, self efficacy(SE), instrumental activities of daily living(IADL), and quality of life (QL), and their relationships among the elderly Data were collected from 47 noninstitutionalized elderly dwell-ing in their own homes and 43 institutionalized elderly living in homes for older people. The ages of the subjects were 65 years and over. The data were col lected from January 20th to February 20th, 1995. Physical fitness was measured with T.K. K dyna mometer, grip dynamometer, stop watch, and Purdue pegboard. Structured questionnaires developed by Kim by Lawton & Brody, and by Ro were adopted to measure SE, IADL, and QL, respectively. The data were analyzed using t-test, ANOVA, and Pearson correlation coefficients. The results were as follows : 1. The noninstitutionalized elderly had higher scores in such measures of physical fitness as body weight, skinfold thickness, flexibility and coordination as compared to the institutionalized elderly. 2. On the following measures of physical fitness, men showed higher levels than women ; in height when standing, height when sitting, body weight, and muscle strength. Women had more trunk flexibility than men. 3. Muscle strength was positively correlated with height when standing, height when sitting, and body weight. The following measures of physical fitness, muscle strength, flexibility and coordi nation, were negatively correlated with "up and go”. 4. The noninstitutionalized elderly had higher scores in SE(t=2.28, p<0.05), IADL(t=2.24, p<0.05), and QL(t=2.41, p<0.05) as compared to the institutionalized elderly. 5. SE was positively correlated with both IADL(r=0.41, p<0.001) and QL(r=0.54, p<0.001), and the latter two variables were a positively correlated (r=0.30, p<0.001). 6. SE was positively correlated with the physical fitness measures of height when standing, body weight, strength of leg muscles, strength of back muscles, grip strength, and level of touching the floor, but negatively correlated with "up and go”. 7. Positive correlations were revealed between IADL and the physical fitness measures of height, strength of leg muscles, level of trunk muscle extension, level of touching the floor, and coordination. The IADL was negatively correlated with “up and go”. 8. QL was positively correlated with body weight (r=0.28, p<0.01) and skinfold thickness (r=0.26, p<0.05). 9. Age was negatively correlated with the physical fitness measures of height when standing, height when sitting, “up and go”, strength of leg muscles, strength of back muscles, grip strength, level of trunk muscle extension, and coordination. 10. Age was also negatively correlated with SE (r=-0.24, p<0.05) and IADL(r=-0.22, p<0.05). The above results suggest that caring elderly in their own homes were more effective and that nursing interventions to enhance physical fitness, SE, IADL, and QL especially for the institutionalized elderly are stressed.
