The elderly population has been dramatically increasing over the past years, but most of the population has developed chronic diseases and handicaps due to aging. High-intensity resistance training is one of the most effective ways to improve muscular strength, but it is unclear whether body composition and functional fitness would be increased by high-intensity resistance training. The aim of this investigation was to explore whether 12 weeks of high-intensity training would improve muscular strength, body composition, and functional fitness in women over the age of 70 years. Twenty-four participants were randomly assigned to a high-intensity resistance training group (n=8), a low-intensity resistance training group (n=8), and a control group (n=8). The experimental groups exercised 3 days per week for 12 weeks at a local fitness center. An analysis of variance(ANOVA) with repeated measures was used for analysis. The results showed that there was a significant improvement in agility and muscular strength following the high-intensity resistance training. Moreover, Moreover, %body fat and body fat mass decreased significantly after the 12 weeks of high-intensity resistance training(p<0.05). Based on these results, it was concluded that high-intensity resistance training is efficient for women over the age 70 years in increasing their muscular strength and functional fitness and reducing their total body fat mass.

Blockchain is a core technology to solve personal information leakage and data management issues, which are limitations of existing Genomic Sequencing services. Due to continuous cost reduction and deregulation, the market size of Genomic Sequencing has been increasing, also the potential of services is expected to increase when Blockchain's security and connectivity are combined. We created our research model by combining the Technology Acceptance Model (TAM) and the Innovation Resistance Theory also analyzed the factors affecting the acceptance intention and innovation resistance of the Blockchain Based Genomic Sequencing Information Platform. A survey was conducted on 150 potential users of Blockchain and Genomic Sequencing services. The analysis was conducted by setting the four Blockchain variables: Security, transparency, availability, and diversity). Also, we set the Perceived Usefulness, Perceived risk, and Perceived Complexity for Technology Acceptance and Innovation Resistance variables and analyzed the effect of the characteristics of the Blockchain on acceptance intention and innovation resistance through these variables. Through this analysis, key variables that need to be considered important to reduce resistance and increase acceptance intention could be identified. This study presents innovation factors that should be considered in companies preparing a new Blockchain Based Genomic Sequencing Information Platform.

There are many studies on the adoption intentions for mobile banking. But there are no apparent effect on the popularity of it. This is so because the users have resistance to innovation on Mobile Banking. Therefore, it is necessary to identify empirically the problem of user resistance. In this paper, we identified hindrance factors of mobile banking with previous papers. And then we conducted empirical study by survey reply from undergraduates and graduate students in China. The results of this study are as follows. Social Influence and Perceived Complexity have positive effect on Perceived Risk, and Trust has negative effect on Perceived Risk. Perceived Security and Perceived Protection of Private information have no effect on Perceived Risk. Perceived Risk has effect on User Resistance. The significance of this paper is that financial institutions and telecommunications companies of China could potentially establish new and more accurate strategies based on the resistance factors identified in this paper to gain more profits.

Purpose: The purpose of this study was to investigate the effects of a walking and resistance exercise on body composition and lipid profile in obese women. Methods: Fourty three women were assigned to experimental group (n=21) or control group (n=22). The walking and resistance exercise using elastic band was provided three times a week for 12 weeks. Weight, height, body mass index, body fat percentage, abdominal fatness, skeletal muscle mass, body fatness, total cholesterol, triglyceride, HDL cholesterol, and LDL cholesterol were measured before and after the program. Paired and independent t-tests were performed using SAS program. Results: Weight (t=-5.35, p<.001), body mass index (t=-4.12, p<.001), body fat percentage (t=-2.33, p =.026), and body fatness (t=-4.32, p<.001) were significantly decreased and skeletal muscle mass (t=2.09, p =.044) was significantly increased after the walking and resistance exercise. Also, total cholesterol (t=-3.03, p =.006) and LDL cholesterol (t=-2.70, p =.011) were significantly decreased and HDL cholesterol (t=2.05, p =.046) was significantly increased after the exercise program. Conclusion: According to the study result, exercise led a positive outcome on obese women in their 30~40s. The walking and resistance exercise will contribute to the improving body composition and lipid profile in this population.

This study was conducted to select low toxic insecticides against natural enemies, and to evaluate resistance stability and cross-resistance to resistance strain for the fulfillment of integrated pest management development. Toxicity of imidacloprid and spinosad to Amblyseius cucumeris was relatively low regardless of the adopting test methods. In addition, those to the Amblyseius fallacis was also low by slide dipping method. The slide dipping method was useful to eliminate repellency effect by mites to the tested insecticides. Mortality of A. fallacis to deltamethrin recorded in 1994 and 1999 was 21.6% and 7.4%, respectively. Meanwhile, the permethrin-resistanct strain of A. fallacis was maintained its resistance to deltamethrin. However, the cross-resistance to the newly introduced insecticides namely imidacloprid, fipronil, chlorfenapyr, abamectin, and spinosad. was relatively low.

This study investigates to investigate the factors that influence user resistance of mobile payment services. We suggested individual and technical characteristics of mobile payment services as factors influencing perceived risk and user resistance. In addition, we suggested negative security recognition as moderating variable. To test the proposed hypotheses, we collected 349 survey responses from the users of mobile payment services and conducted structural equation modeling with SmartPLS2.0. The results show that, first, negative social influence, risk aversion and distrust in existing services had an effect on the perceived risk. Second, the pace of change and vulnerability had an effect on the perceived risk. Third, perceived risk affected the user resistance while negative security recognition is related to the relationship between perceived risk and user resistance.
