class="card-text"><strong>Abstract:</strong></p> One of the most important issue is to ensure the safety of long-term waste storage containers in which fuel debris and radioactive materials are accumulated. In this case, hydrogen generated by water decomposition by radiation is accumulated in the container for a long period of time, so it is necessary to reduce the concentration of hydrogen in the container. In addition, a condition that any power supplies from the outside of the container are unnecessary is requested. Then, radioactive waste storage containers with the passive autocatalytic recombiner (PAR) would be effective. The radioactive waste storage container with PAR was used for moving the fuel debris of the Three Mile Island Unit 2 to the storage location. However, the effect of PAR is not described in detail. Moreover, the reduction of hydrogen concentration during the long-term storage period was performed by the venting system, which was installed on the top of the container. Therefore, development of a long-term storage container with PAR was started with the aim of safely storing fuel debris picked up at the Fukushima Daiichi Nuclear Power Plant for a long period of time. A fundamental experiment for reducing the concentration of hydrogen which generates in a nuclear waste long-term storage container was carried out using a small-scale container with PAR. Moreover, the circulation flow behavior of hydrogen in the small-scale container resulting from the natural convection by the decay heat was clarified. In addition, preliminary numerical analyses were performed to predict the experimental results regarding the circulation flow behavior and the reduction of hydrogen concentration in the small-scale container. From the results of the present study, the validity of the container with PAR was experimentally confirmed on the reduction of hydrogen concentration. In addition, it was predicted numerically that the circulation flow behavior of hydrogen in the small-scale container is blocked by steam which generates by chemical reaction of hydrogen and oxygen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20behavior" title="hydrogen behavior">hydrogen behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=reduction%20of%20concentration" title=" reduction of concentration"> reduction of concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20storage%20container" title=" long-term storage container"> long-term storage container</a>, <a href="https://publications.waset.org/abstracts/search?q=small-scale" title=" small-scale"> small-scale</a>, <a href="https://publications.waset.org/abstracts/search?q=PAR" title=" PAR"> PAR</a>, <a href="https://publications.waset.org/abstracts/search?q=experiment" title=" experiment"> experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=analysis" title=" analysis"> analysis</a> </p> <a href="https://publications.waset.org/abstracts/89008/experimental-and-numerical-studies-on-hydrogen-behavior-in-a-small-scale-container-with-passive-autocatalytic-recombiner" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89008.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Introduction of PMMA-Tag to VHH for Improving Recovery and Immobilization Rate of VHHS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bongmun%20Kang">Bongmun Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kagnari%20Yamakawa"> Kagnari Yamakawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshihisa%20Hagihara"> Yoshihisa Hagihara</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuji%20Ito"> Yuji Ito</a>, <a href="https://publications.waset.org/abstracts/search?q=Michimasa%20Kishimoto"> Michimasa Kishimoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoichi%20Kumada"> Yoichi Kumada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The PMMA-tag was genetically fused with the C-terminal region of VHH molecules. This antibody, VHH, is known as a single-chain domain, which is devoid of light chains. The PMMA-tag, which could affect the isoelectric point (pI) changeable with a charge of amino acid in VHHs were closely related to the solubility of VHH molecules during refolding. The genetic fusion of PMMA-tag to C-terminal region of VHHs significantly affects the recovery of their soluble protein during refolding by 50 mM TAPS at pH 8.5. It could be refolded with a recovery of more than 95% by dialysis at pH 8.5. A marked difference in the antigen-binding activities in the adsorption state was significantly high in VHH-PM compared to the wild type of VHH. There are approximately 8-fold differences in the antigen-binding activities in the adsorption state between VHH-PM and VHH. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=VHH" title="VHH">VHH</a>, <a href="https://publications.waset.org/abstracts/search?q=PMMA-tag" title=" PMMA-tag"> PMMA-tag</a>, <a href="https://publications.waset.org/abstracts/search?q=isoelectric%20point" title=" isoelectric point"> isoelectric point</a>, <a href="https://publications.waset.org/abstracts/search?q=pH" title=" pH"> pH</a>, <a href="https://publications.waset.org/abstracts/search?q=Solubility" title=" Solubility"> Solubility</a>, <a href="https://publications.waset.org/abstracts/search?q=refolding" title=" refolding"> refolding</a>, <a href="https://publications.waset.org/abstracts/search?q=immobilization" title=" immobilization"> immobilization</a>, <a href="https://publications.waset.org/abstracts/search?q=ELISA" title=" ELISA"> ELISA</a> </p> <a href="https://publications.waset.org/abstracts/19089/introduction-of-pmma-tag-to-vhh-for-improving-recovery-and-immobilization-rate-of-vhhs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19089.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">419</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Development of a Real-Time Brain-Computer Interface for Interactive Robot Therapy: An Exploration of EEG and EMG Features during Hypnosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Alimardani">Maryam Alimardani</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazuo%20Hiraki"> Kazuo Hiraki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a framework for development of a new generation of therapy robots that can interact with users by monitoring their physiological and mental states. Here, we focused on one of the controversial methods of therapy, hypnotherapy. Hypnosis has shown to be useful in treatment of many clinical conditions. But, even for healthy people, it can be used as an effective technique for relaxation or enhancement of memory and concentration. Our aim is to develop a robot that collects information about user’s mental and physical states using electroencephalogram (EEG) and electromyography (EMG) signals and performs costeffective hypnosis at the comfort of user’s house. The presented framework consists of three main steps: (1) Find the EEG-correlates of mind state before, during, and after hypnosis and establish a cognitive model for state changes, (2) Develop a system that can track the changes in EEG and EMG activities in real time and determines if the user is ready for suggestion, and (3) Implement our system in a humanoid robot that will talk and conduct hypnosis on users based on their mental states. This paper presents a pilot study in regard to the first stage, detection of EEG and EMG features during hypnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hypnosis" title="hypnosis">hypnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=robotherapy" title=" robotherapy"> robotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=brain-computer%20interface%20%28BCI%29" title=" brain-computer interface (BCI)"> brain-computer interface (BCI)</a> </p> <a href="https://publications.waset.org/abstracts/53787/development-of-a-real-time-brain-computer-interface-for-interactive-robot-therapy-an-exploration-of-eeg-and-emg-features-during-hypnosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53787.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">256</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Interpersonal Body-Synchronization in Young Children When Watching Video Together</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeko%20Takahashi">Saeko Takahashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazuo%20Hiraki"> Kazuo Hiraki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Is it more fun to watch videos together than watching alone? Previous studies showed that synchronizing with others enhances subsequent prosocial behavior and affiliation, and conversely, prosocial individuals tend to coordinate with a partner to a greater extent. However, compared to adults, less is known about interpersonal coordination of young children in real-life situations because most studies have focused on children’s particular movement using specific tools or tasks in a laboratory setting. It has also been unclear if prosociality of young children affect the extent of interpersonal coordination within dyads. The present study examined data from motion capture of five body parts of 4-year-old dyads watching the same stimuli together or alone. A questionnaire survey including participants’ prosocial trait was also conducted. The wavelet coherence of each body parts within dyads was calculated as a measure of the extent of interpersonal coordination. Results showed that the dyads became significantly more coordinated in a social situation compared to a non-social situation. Moreover, dyads with averagely higher prosociality were more coordinated. These results shed some light on the development of interpersonal coordination in terms of social ability in young children. This study also offers a useful method for a study of spontaneous coordination in young children and infants without instructions or verbal responses. <p class="card-text"><strong>Keywords:</strong>
