The purpose of this research was to evaluate the size fitness of ready-made jacket and their demands through the survey of the middle aged women, and having them try on the jackets, and present the basic data on the ways to increase the fitness by better size controls. The jackets, that were modified and improved through the experiment of the women with triangle-figure in their 50s, were compared and evaluated. The experiment showed a difference in the appearance and the motional function. The triangle-figure had the lowest fitness, thus most uncomfortable. The triangle-figure is characterized by the large waist, leaving small space between body and clothes. This creates the wrinkles in bust or waist area, making it uncomfortable to move. The jacket, that was produced by modifying these problem areas and developing research pattern, showed a good results on the appearances and function.

In this paper, the method of material constants extraction in a thin-film bulk acoustic resonator(FBAR) using a genetic algorithm(GA) is proposed. The material constants are extracted from the input impedance of a FBAR by a GA optimizer. The characteristics of the FBAR input impedance affected by the material constants were studied to decide the fitness function for GA. As a result, the fitness was estimated by the series- and parallel -resonance frequencies and the FBAR bandwidth, as determined from the input impedance of the FBAR. A flowchart for the GA and a procedure fur the proposed extraction method are explained in detail, and the results of the material constants extraction are presented.

The purpose of this work is to develop the FES controller that can cope with the muscle fatigue which is one of the most important problems of current FES (Functional Electrical Stimulation). The feasibility of the proposed FES controller was evaluated by simulation. We used a fitness function to describe the effect of muscle fatigue and recovery process. The FES control system was developed based on the biological neuronal system. Specifically, we used PD (Proportional and Derivative) and GC (Gravity Compensation) control, which was described by the neuronal feedback structure. It was possible to control of multiple joints and muscles by using the phase-based PD and GC control method and the static optimization. As a result, the proposed FES control system could maintain the cycling motion in spite of the muscle fatigue. It is expected that the proposed FES controller will play an important role in the rehabilitation of SCI patient.

It is often necessary to predict the vibration patterns of the structures from the signals of finite number of vibration sensors. This study presents the optimal placement of vibration sensors by applying the genetic algorithm and the modal expansion method. The modal expansion method is used to estimate the vibration response of the whole structure. The genetic algorithm is used to estimate the optimal placement of vibration sensors. Optimal sensor placement can be obtained so that the fitness function is minimized in the genetic algorithm. This paper discusses the comparison of the performances of two types of fitness functions, modal assurance criteria(MAC) and condition number( CN). As a result, the estimation using MAC shows better performance than using CN.

Physical activity has been effective in enhancing quality of life and physical fitness of older adults over relatively short periods of time. However, little is known about the Yoga-based exercise program on physiological changes and physical fitness with psychological variables in elderly women. The purpose of this study is to investigate the effect of Yoga- based exercise program on physiological, psychological factors and physical fitness in elderly women. Forty-four elders were recruited from the public health center. They were divided into exercise training group(n=22) and control group(n=22). The training group participating in 10 weeks of Yoga-based exercise program. Data was analyzed with descriptive statistics, the chi-square test, Fisher's Extract test, and ANCOVA to evaluate body fat, spine ROM, blood pressure, cholesterol, depression, life satisfaction, ADL and physical fitness. There was a significant improvement in blood pressure, total cholesterol, precent of body fat, physiological function, depression, life satisfaction, ADL and physical fitness in the exercise training group than that of the control group. From the results, Yoga-based interventions designed to improve various variables were equally acceptable to elderly women.

This study aims to analyze exercise cases and issues using smart devices and technologies, and to present the development direction of a smart exercise environment suitable for the wellness life of active seniors with high activity and economic power unlike the existing silver generation. In the fitness industry, the subscription economy that regularly receives or uses necessary exercise tools, services, and digital content is expanding, and business models based on hardware sales and content subscription continue to emerge. In order to have value competitiveness as a platform that provides active seniors with integrated exercise services for health care, not only fitness centers, but also home training exercise equipment, fitness-related applications, and smart wearable device markets should be organically connected to form an expanded total platform. In order to have value competitiveness as a platform that provides active seniors with integrated exercise services for health care, not only fitness centers, but also home training exercise equipment, fitness-related applications, and smart wearable device markets should be organically connected to form an expanded total platform. The linkage of the digital healthcare function, which provides real-time changes to exercise programs based on continuous monitoring and feed back through wearable devices before, after, and during exercise by receiving and selecting exercise programs suitable for individual health status, is the differentiating factor in the smart fitness model.

Purpose: In this study a recreational combination gymnastics program was provided for women 75 years of age or older and the effects on physical fitness (grip strength, static balance, ability to do complex movement), depression, cognitive function and quality of life were examined. Methods: A quasi-experimental study employing a nonequivalent control group, pre-post design was conducted. Participants included 53 women elders whose cognitive function was within the normal range. The women were assigned to an experimental group (27) or a control group (26). The intervention was conducted twice a week for a period of 12 weeks. Chi-square test, t-test, paired t-test, Wilcoxon rank sum test and Wilcoxon signed rank test were used for data analysis. Results: Following completion of the program, left grip strength (t=2.17, p=.035), right grip strength (t=2.04, p=.046), static balance (t=-2.18, p=.030), depression (z=-2.88, p=.004), cognitive function (t=3.96, p<.001), and quality of life (t=-3.19, p=.002) were significantly better in the experimental group. Conclusion: Findings from this study indicate that recreational combination gymnastics programs are effective in enhancing physical fitness, cognitive function, and quality of life and in decreasing depression for female elders and could therefore be regarded as positive programs for promotion of physical and mental health for older women.

The purpose of this study was to verify exercise effect of horse riding exercise according to estimate basal physical fitness and activities of daily living(ADL) function in the aged. Participants were nineteen peoples who have no impediment of activity. They performed horse riding exercise using SRider(Neipplus, Co., Korea) at sixty minutes a day. Exercise has progressed three days a week for eight weeks. We measured trunk flexion, sit up, whole body reaction, leg strength and maximal oxygen uptake as basal physical fitness. Also three meter gait, single stance with eyes opened and single stance with eyes closed as ADL function were estimated once a month. The result of legs strength and whole body reaction showed the higher significantly than before the exercise. Moreover, the result of three meter walking ability only increased significantly among the ADL function. This means that horse riding exercise might be activated continuous muscular contraction with maintained tonus of muscle. We thought that continuous movement of horse riding could be lead to isometric muscle contraction in lower limbs. Our study found that horse riding exercise could improve lower strengths and muscle reaction for exercise effect. Also we suggested that horse riding exercise could be adapted to exercise methods that could provide rehabilitation and treatment enough for the aged or disabled person.

This paper introduces our three approaches to reduce the burden of human interactive EC operators: (1) improvement of the interface of presenting individuals, (2)improvement of the interface of inputting fitness values, and (3) fast EC convergence. We propose methods to display individuals in order of predicted fitness values by neural networks or Euclidean distance measure for (1), to input quantized fitness values for (2), and to make a new elite by approximating the EC search space with a quadratic function for (3). They are evaluated through simulations and subjective testes, and their effects have shown.
