When a Woman Betrays the Nation: an Analysis of Moto Hagio’s The Heart of Thomas
This thesis discusses The Heart of Thomas (1974), the representative shōjo manga (girl’s comic) of Moto Hagio, who is often called “The Magnificent Mother of shōjo manga” or “The Goddess of shōjo manga” and was the first shōjo manga creator to win a Meadal of Honor for artistic achievement from the Japanese government. Although The Heart is highly regarded, even worshiped, by fans of manga, scholars have been slow to give it due consideration as an important document of social history, especially of women’s social history. The following study takes a personal approach, attempting to analyze The Heart in the context of the author herself, both in terms of her biographical circumstances and inner psychology. The first section takes up Hagio’s “outer world” and describes the formidable challenges she faced in composing The Heart, both from the world and from her own family. The second turns inwards and explores the ways in which the plot and characters of The Heart have a special, psychological resonance for Hagio, especially in the context of the psychoanalytic theories of Ronald Fairbairn. The third and final section pushes these theories even further and suggests that Hagio’s characters are “split egos” of Hagio herself, redressing traumas in her real life. The conclusion ventures a few explanations for the massive popularity of The Heart and its full significance as a document of social history in a nationalist context
Radiotherapy quality assurance review in a multi-center randomized trial of limited-disease small cell lung cancer: the Japan Clinical Oncology Group (JCOG) trial 0202
<p>Abstract</p> <p>Background</p> <p>The purpose of this study was to analyze the radiotherapy (RT) quality assurance (QA) assessment in Japan Clinical Oncology Group (JCOG) 0202, which was the first trial that required on-going RT QA review in the JCOG.</p> <p>Methods</p> <p>JCOG 0202 was a multi-center phase III trial comparing two types of consolidation chemotherapy after concurrent chemoradiotherapy for limited-disease small cell lung cancer. RT requirements included a total dose of 45 Gy/30 fx (bis in die, BID/twice a day) without heterogeneity correction; elective nodal irradiation (ENI) of 30 Gy; at least 1 cm margin around the clinical target volume (CTV); and interfraction interval of 6 hours or longer.

Experimental Evaluation of Publish/Subscribe-based Spatio-Temporal Contents Management on Geo-Centric Information Platform
Cross-domain data fusion is becoming a key driver to growth of the numerous and diverse applications in IoT era. Nevertheless, IoT data obtained by individual devices are blindly transmitted to cloud servers. We here focus on that the IoT data which are suitable for cross-domain data fusion, tend to be generated in the proximity, and thus propose a Geo-Centric Information Platform (GCIP) for the management of Spatio-Temporal Contents (STCs) generated through the cross-domain data fusion. GCIP enables to keep STCs near the users (at an edge server). In this paper, we practically examine the fundamental functions of the GCIP from two aspects: (1) Geo-location aware data collection and (2) Publish/Subscribe-based STC production. Furthermore, we implement a proof-of-concepts (PoC) of GCIP and conduct experiments on a real IPv6 network built on our campus network. In this experiment, we showed that multiple types of IoT data generated in the proximity can be collected on the edge server and then a STC can be produced by exploiting the collected IoT data. Moreover, we demonstrated that the Publish/Subscribe model has a potential to be effective for STC management.22nd International Conference on Network-Based Information Systems(NBiS 2019), September 5-7, 2019, Oita, Japa
Matching based content discovery method on Geo-Centric Information Platform
We have proposed a concept of new information platform, Geo-Centric information platform (GCIP), that enables IoT data fusion based on geolocation. GCIP produces new and dynamic contents by combining cross-domain data in each geographic area and provides them to users. In this environment, it is difficult to find appropriate contents requested by a user because the user cannot recognize what contents are created in each area beforehand. In this paper, we propose a content discovery method for GCIP. This method evaluates the relevancy between topics specified in user requests and topics representing IoT data used for creating contents, called matching, and presents the candidates for the desired contents based on the relevancy. Simulation results showed that appropriate contents can reliably be discovered in response to user’s request.12th International Workshop on Information Network Design (WIND-2020), in conjunction with 12th International Conference on Intelligent Networking and Collaborative Systems (INCoS-2020), August 31st - September 2nd, 2020, University of Victoria, Canada(新型コロナ感染拡大に伴い、現地開催中止
Oral hypofunction in the older population : Position paper of the Japanese Society of Gerodontology in 2016
Background: There is growing international interest in identifying the effects of ageing on oral health and on appropriate strategies for managing oral disorders. The Japanese Society of Gerodontology (JSG), as the official representative of researchers and clinicians interested in geriatric dentistry in Japan, makes several recommendations on the concept of “oral hypofunction.”
Aims: This study proposes diagnostic criteria and management strategies to reduce the risk of oral hypofunction among older people.
Conceptual Framework: We define oral hypofunction as a presentation of 7 oral signs or symptoms: oral uncleanness; oral dryness; decline in occlusal force; decline in motor function of tongue and lips; decline in tongue pressure; decline in chewing function; and decline in swallowing function. The criteria of each symptom were determined based on the data of previous studies, and oral hypofunction was diagnosed if the criteria for 3 or more signs or symptoms were met.
Conclusions: We recommend that more evidence should be gathered from clinical studies and trials to clarify our diagnostic criteria and management strategies
Visual and Vestibular Inputs Affect Muscle Synergies Responsible for Body Extension and Stabilization in Sit-to-Stand Motion
The sit-to-stand motion is a common movement in daily life and understanding the mechanism of the sit-to-stand motion is important. Our previous study shows that four muscle synergies can characterize the sit-to-stand motion, and they have specific roles, such as upper body flexion, rising from a chair, body extension, and posture stabilization. The time-varying weight of these synergies are changed to achieve adaptive movement. However, the relationship between sensory input and the activation of the muscle synergies is not completely understood. In this paper, we aim to clarify how vestibular and visual inputs affect the muscle synergy in sit-to-stand motion. To address this, we conducted experiments as follows. Muscle activity, body kinematics, and ground reaction force were measured for the sit-to-stand motion under three different conditions: control, visual-disturbance, and vestibular-disturbance conditions. Under the control condition, the participants stood without any intervention. Under the visual-disturbance condition, the participants wore convex lens glasses and performed the sit-to-stand motion in a dark room. Under the vestibular-disturbance condition, a caloric test was performed. Muscle synergies were calculated for these three conditions using non-negative matrix factorization. We examined whether the same four muscle synergies were employed under each condition, and the changes in the time-varying coefficients were determined. These experiments were conducted on seven healthy, young participants. It was found that four muscle synergies could explain the muscle activity in the sit-to-stand motion under the three conditions. However, there were significant differences in the time-varying weight coefficients. When the visual input was disturbed, a larger amplitude was found for the muscle synergy that activated mostly in the final posture stabilization phase of the sit-to-stand motion. Under vestibular-disturbance condition, a longer activation was observed for the synergies that extended the entire body and led to posture stabilization. The results implied that during human sit-to-stand motion, visual input has less contribution to alter or correct activation of muscle synergies until the last phase. On the other hand, duration of muscle synergies after the buttocks leave are prolonged in order to adapt to the unstable condition in which sense of verticality is decreased under vestibular-disturbance
Usefulness of 11C-Methionine Positron Emission Tomography for Monitoring of Treatment Response and Recurrence in a Glioblastoma Patient on Bevacizumab Therapy: A Case Report
Recently developed molecular targeted therapies such as bevacizumab (BEV; Avastin) therapy have therapeutic efficacy for glioblastoma. However, it is difficult to distinguish between a tumor response and nonenhancing tumor progression with conventional magnetic resonance imaging (MRI) after BEV administration. Here we present a recurrent glioblastoma case in which 11C-methionine positron emission tomography (MET-PET) provided useful information for detecting tumor recurrence after complete remission, as assessed by the Response Assessment in Neuro-Oncology criteria. A 47-year-old male with a left frontal lobe glioblastoma experienced recurrence 6 months postoperatively. We administered BEV concomitantly with temozolomide, subsequent to gamma knife surgery. Two months after starting BEV, complete remission was obtained. MET uptake on PET gradually decreased and had nearly disappeared 4 months after initiating BEV. No enhanced area was seen on MRI for 17 months after BEV initiation. Nevertheless, MET-PET revealed recurrence, visualized as nonenhancing tumor progression. MET-PET provides useful information for detecting glioblastoma recurrence, which lacks contrast enhancement on MRI after BEV therapy
Short-Term Synaptic Plasticity in the Dentate Gyrus of Monkeys
The hippocampus plays an important role in learning and memory. Synaptic plasticity in the hippocampus, short-term and long-term, is postulated to be a neural substrate of memory trace. Paired-pulse stimulation is a standard technique for evaluating a form of short-term synaptic plasticity in rodents. However, evidence is lacking for paired-pulse responses in the primate hippocampus. In the present study, we recorded paired-pulse responses in the dentate gyrus of monkeys while stimulating to the medial part of the perforant path at several inter-pulse intervals (IPIs) using low and high stimulus intensities. When the stimulus intensity was low, the first pulse produced early strong depression (at IPIs of 10–30 ms) and late slight depression (at IPIs of 100–1000 ms) of field excitatory postsynaptic potentials (fEPSPs) generated by the second pulse, interposing no depression IPIs (50–70 ms). When the stimulus intensity was high, fEPSPs generated by the second pulse were depressed by the first pulse at all IPIs except for the longest one (2000 ms). Population spikes (PSs) generated by the second pulse were completely blocked or strongly depressed at shorter IPIs (10–100 or 200 ms, respectively), while no depression or slight facilitation occurred at longer IPIs (500–2000 ms). Administration of diazepam slightly increased fEPSPs, while it decreased PSs produced by the first pulse. It also enhanced the facilitation of PSs produced by the second stimulation at longer IPIs. The present results, in comparison with previous studies using rodents, indicate that paired-pulse responses of fEPSPs in the monkey are basically similar to those of rodents, although paired-pulse responses of PSs in the monkey are more delayed than those in rodents and have a different sensitivity to diazepam
High-Energy Molecular-Frame Photoelectron Angular Distributions: A Molecular Bond-Length Ruler
We present an experimental and theoretical study of core-level ionization of
small hetero- and homo-nuclear molecules employing circularly polarized light
and address molecular-frame photoelectron angular distributions in the light's
polarization plane (CP-MFPADs). We find that the main forward-scattering peaks
of CP-MFPADs are slightly tilted with respect to the molecular axis. We show
that this tilt angle can be directly connected to the molecular bond length by
a simple, universal formula. The extraction of the bond length becomes more
accurate as the photoelectron energy is increased. We apply the derived formula
to several examples of CP-MFPADs of C 1s and O 1s photoelectrons of CO, which
have been measured experimentally or obtained by means of ab initio modeling.
The photoelectron kinetic energies range from 70 to 1000~eV and the extracted
bond lengths agree well with the known bond length of the CO molecule in its
ground state. In addition, we discuss the influence of the back-scattering
contribution that is superimposed over the analyzed forward-scattering peak in
case of homo-nuclear diatomic molecules as N
Changes in serum antibody titers after vaccination for COVID-19 and evaluation of post-vaccination health conditions
Introduction: The coronavirus disease 2019 (COVID-19) vaccine has preventive effects and high immunogenicity, but the outcomes of vaccination have not been widely reported. The goal of this study was to examine serum antibody titers before and after vaccination and to evaluate post-vaccination health conditions. Methods: The subjects were 2,304 medical workers (mean age 41 years) at Kawasaki Gakuen who agreed to participate in the study and underwent COVID-19 vaccination, beginning in March 2021. Serum IgG antibody titers for SARS-CoV-2 spike protein were measured before the first vaccination and 4 weeks after the second vaccination. Health conditions were observed for 4 weeks after the second vaccination. Results: The rates of seroconversion, seroprotection, and change in geometric mean antibody titer at 4 weeks after the second vaccination were 99.9%, 99.9%, and 2,685.5 (95% CI 587.8-5,319.2), respectively, suggesting high immunogenicity. After the first vaccination, pain, enlargement, and reddening occurred at the local injection site, and systemic side effects included fatigue, headache, physical pain, chill, nausea, and fever. After the second vaccination, the incidence of pain decreased, but those of other events increased. There were no serious side effects requiring hospitalization. In logistic regression analysis, sex, age, fever,chill, and lymph node enlargement after the second vaccination were associated with a change in antibody titer. Conclusions: Serum antibody titers suggested high immunogenicity of the COVID-19 vaccine and a health condition survey confirmed the safety of the vaccine. Systemic side effects may serve as an index of immunization (acquisition of antibody) by the vaccine
