EstS1, a newly identified thermostable esterase from Sulfobacillus acidophilus DSM10332, was heterologously expressed in Escherichia coli and shown to enzymatically degrade phthalate esters (PAEs) to their corresponding monoalkyl PAEs. The optimal pH and temperature of the esterase were found to be 8.0 and 70°C, respectively. The half-life of EstS1 at 60°C(More)
This paper describes the design of a digital fork and a mobile interactive and persuasive game for a young child who is a picky eater and/or easily distracted during mealtime. The system employs Ubicomp technology to educate children on the importance of a balanced diet while motivating proper eating behavior. To sense a child's eating behavior, we have(More)
This paper presents the design and implementation of a wearable oral sensory system that recognizes human oral activities, such as chewing, drinking, speaking, and coughing. We conducted an evaluation of this oral sensory system in a laboratory experiment involving 8 participants. The results show 93.8% oral activity recognition accuracy when using a(More)
We propose a fork-type sensing device, Sensing Fork, which detects children's eating behavior (eating actions and chosen food) and a smartphone game to address children's eating problems. This paper describes the design and implementation of the Sensing Fork prototype and the play-based eating game called Hungry Panda.
We present a fork-type sensing device called the Sensing Fork that detects the eating behavior of children (food choice and eating actions), and a smartphone game to address children's eating problems based on their eating behavior. This paper describes the design and implementation of the Sensing Fork prototype and a play-based eating game called Hungry(More)
To facilitate the collection of patient biosignals, designing extensible sensing devices in which sensor management is simplified is essential. This paper presents BioScope, an extensible sensing system that facilitates collecting data used in nursing assessments. We conducted experiments to demonstrate the potential of the system. The results obtained in(More)
BACKGROUND The increased rates of cardiovascular morbidity and mortality in patients with psoriasis are not adequately explained by traditional risk factors. Whether concomitant sleep disorders (SDs) modify the risk of cardiovascular disease (CVD) in patients with psoriasis remains unknown. METHODS Using the Taiwan National Health Insurance Research(More)
This study was conducted to determine the relation between the dynamic modulus of elasticity and the static modulus of elasticity, and the relation between the dynamic modulus of elasticity and the modulus of rupture of mandarin peel–sawdust composite boards. The result of this study was as follows: There was highly close linear correlation between the(More)
INTRODUCTION An association between psoriasis and sexual dysfunction (SD) has been explored. However, the risk of SD after the diagnosis of psoriasis relative to the age-matched general population remains unknown. Aim.  To clarify the risk of developing SD in male patients with psoriasis. METHODS From 2000 to 2001, we identified 12,300 male patients with(More)
