In order to use effectively renewable energy sources, we propose a new system, called Advanced Superconducting Power Conditioning System (ASPCS) that is composed of Superconducting Magnetic Energy Storage (SMES), Fuel Cell-Electrolyzer (FC-EL), hydrogen storage and DC/DC and DC/AC converters in connection with a liquid hydrogen station for fuel cell vehicles. The ASPCS compensates the fluctuating electric power of renewable energy sources such as wind and photovoltaic power generations by means of the SMES having characteristics of quick response and large Input-Output power, and hydrogen energy with FC-EL having characteristics of moderate response and large storage capacity. The moderate fluctuated power of the renewable energy is compensated by a trend forecasting method with the Artificial Neural Network. In case of excess of the power generation by the renewable energy to demand it is converted to hydrogen with EL. In contrast, shortage of the electric power is made up with FC. The faster fluctuation power that cannot be compensated by the forecasting method is effectively compensated by SMES. In the ASPCS, the SMES coil with an MgB2 conductor is operated at 20 K by using liquid hydrogen supplied from a liquid hydrogen tank of the fuel cell vehicle station. The necessary storage capacity of SMES is estimated as 50 MJ to 100 MJ depending on the forecasting time for compensating fluctuation power of the rated wind power generation of 5.0 MW. As a safety case, a thermosiphon cooling system is used to cool indirectly the MgB2 SMES coil by thermal conduction. In this paper, a trend forecasting result of output power of a wind power generation and the estimated storage capacity of SMES are reported.

The energy of tagged photons, which were provided from the internal photon tagging system of the Laboratory of Nuclear Science, Tohoku University, has been calibrated using the d（γ,π-pp） reaction. Charged pions and protons in the final state were detected with the Neutral Kaon Spectrometer （NKS2）. Photon energies were obtained from the reaction of d（γ,π-pp）. The derived photon energy was consistent with the design of the tagger system and the previous measurement using electron-positron pair production. The consistency demonstrates the performance of NKS2 and the capability of the photon energy calibration using d（γ,π-pp）.

Background: This crossover trial aimed to examine the efficacy of the Tele-nursing Symptom Management System for Chemotherapy in Outpatient Treatment (T-SCOT) in reducing the side effects in patients undergoing out-patient chemotherapy. Methods: Using a tablet computer, participants were asked to provide information on various items, including fever, nausea, hair loss, fatigue, and vital signs. Both the participants and researchers automati-cally monitored time-dependent changes in symptoms, and the researchers proposed concrete measures to reduce patients’ complications. The primary endpoint was the M. D. Anderson Symptom Inventory (MDASI-J) score. The secondary endpoint, Quality of Life (QOL) was evaluated using the Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs (QOL- ACD). Results: This study included 20 patients who met all the inclusion cri-teria, 14 of whom agreed to participate in the study. There was no significant difference between the MDASI-J and QOL-ACD pre- and post-comparison of the primary and secondary evaluations in the intervention group. The control group had significantly higher scores 3 months after the intervention for symptom intensity (p = 0.04) and symptom-induced disruption to life (p = 0.03), and the symptoms worsened. The QOL-ACD had significantly lower scores for activity (p = 0.03), overall QOL (p = 0.04), and total QOL score (p = 0.02), resulting in a lower quality of life. Conclusions: Participants used the Internet to obtain information on treatments and side effects and changed their behavior in daily life. It is speculated that the Information and Commu-nications Technology (ICT) literacy in older adults has improved, and they are benefiting from digital utilization.

During outpatient chemotherapy, adverse events occurring at home must be carefully monitored. We have developed a tele-nursing system that can store physical information such as blood pressure and pulse measured by cancer patients in the cloud by using Bluetooth, which is wireless communication technology, and collect information from remote locations. The tele-nursing system name is T-SCOT. The purpose of this study is to conduct a randomized controlled trial to investigate the efficacy of T-SCOT intervention. Participants are those who receive T-SCOT intervention plus Care as usual as the intervention group, and those who receive only Care as usual as the control group. T-SCOT includes the following five steps: 1) Answer questions related to side effects of chemotherapy [10 items];2) Measure blood pressure, pulse, body temperature, and SPO2. The measured data is automatically saved in the cloud via Bluetooth;3) Watch a video of coping behavior for side effects;4) The data entered by the patient is visualized as a line graph;5) Utilize the videophone function with researchers if you have any problems or troubles. Utilization of ICT in telenursing makes it possible to visualize patient’s physical information and contributes to the reduction of medical expenses.

AIM:To examine the prevalence of gastroesophageal reflux disease (GERD) symptoms in a large unselected general population in Japan. METHODS: In Japan, mature adults are offered regular check-ups for the prevention of gastric cancer. A notice was sent by mail to all inhabitants aged > 40 years. A total of 160 983 Japanese (60 774 male, 100 209 female; mean age 61.9 years) who underwent a stomach check up were enrolled in this study. In addition, from these 160 983 subjects, we randomly selected a total of 82 894 (34 275 male, 48 619 female; mean age 62.4 years) to evaluate the prevalence of abdominal pain. The respective subjects were prospectively asked to complete questionnaires concerning the symptoms of heartburn, dysphagia, and abdominal pain for a 1 mo period. RESULTS: The respective prevalences of the symptoms in males and females were: heartburn, 15.8% vs 20.7%; dysphagia, 5.4% vs 7.8%; and abdominal pain, 6.6% vs 9.6%. Among these symptoms, heartburn was significantly high compared with the other symptoms, and the prevalence of heartburn was significantly more frequent in females than in males in the 60-89-year agegroup. Dysphagia was also significantly more frequent in female patients. CONCLUSION: The prevalence of typical GERD symptoms (heartburn) was high, at about 20% of the Japan population, and the frequency was especially high in females in the 60-89 year age group.

AIM:To test this hypothesis of barrett esophagus (BE) classified into two types and to further determine if there was any correlation between the shape of endoscopically suspected esophageal metaplasia (ESEM), prevalence of reflux esophagitis (RE) and heartburn. METHODS: A total of 6504 Japanese who underwent endoscopy for their annual stomach check-up were enrolled in this study. BE was detected without histological confirmation that is ESEM. We originally classified cases of ESEM into 3 types based on its shape: Tongue-like (T type), Dome-like (D type) and Wave-like (W type) ESEM. The respective subjects were prospectively asked to complete questionnaires concerning the symptoms of heartburn, dysphagia, and abdominal pain for a one-month period. RESULTS: ESEM was observed in 10.3% of 6504 subjects (ESEM < 1 cm, 9.4%; 1 cm ≤ ESEM < 3 cm, 1.7%; ESEM ≥ 3 cm, 0.5%). The frequency of ESEM was significantly higher in males compared with female subjects. Statistical analysis showed that the prevalence of heartburn and RE were significantly higher in the T type ESEM than in the W type ESEM (P < 0.05). CONCLUSION: The T type ESEM was strongly associated with reflux symptoms and RE whereas the W type ESEM was not associated with GERD.
