Aim: Recently, the role of feeding coparenting has gained attention in the child eating research field. The Feeding Coparenting Scale (FCS), a measure of how caregivers interact with their partners when feeding their children was developed in the United States in 2019. However, there is no valid and reliable measure to assess feeding coparenting among caregivers of school-aged children in Japan. Therefore, this study aimed to develop a Japanese version of the FCS (FCS-J) questionnaire for caregivers with school-aged children. Methods: This was a web-based cross-sectional survey completed by caregivers of children aged 10-12 years. A preliminary survey using interviews and a web-based survey was conducted and found that the translated items of the FCS into Japanese were understandable to Japanese people. The developed survey was administered to parents of children at an elementary school. The reliability of the survey was assessed using both test-retest reliability and internal consistency analysis. Exploratory factor analysis was used to test construct validity, and known population validity was examined in relation to attributes, marital satisfaction, and feeding tasks. Results: Findings with 135 parents of school-aged children showed good internal reliability and validity of the FCS-J. The mean score for the overall FCS-J score was 46.2 (SD = 6.2), with Cronbach’s α of 0.72. For the subscales, Cronbach’s α ranged from 0.75 to 0.79. In sum, the present study’s results support the three-factor structure of the FCS in Japanese caregivers in Japan. Conclusions: The developed FCS-J was found to have a certain degree of reliability and validity. In this study, a Japanese version of the FCS-J was developed. .

Crystallization of natural rubber （NR） was investigated in different morphology for NR/styrene bntadiene rubber （SBR） blend and NR/polystyrene-（b）-polyisoprene （SI）/polystyrene （PS） blend. A purified NR （PC-TE） was prepared from pale crape via transesterification. In the blends, PC-TE formed various morphologies; that is, matrix phase, island phase and continuous phase with a nano-scale, respectively, in dependence upon the ratio of the rubbers. The crystallization rate of the blends was also significantly associated with the morphology of the rubbers.

The activated sludge process to remove nitrogen and biochemical oxygen demand （BOD） is reportedly cost-effective for swine wastewater treatment, and it use has thus increased in pig farming. Nitrous oxide （N20） is generated on farms as an intermediate product in nitrification and denitrification, and methane （CH4） is also generated from organic degradation under anaerobic conditions by microorganisms in manure or wastewater. This study was carried out at five activated sludge treatment facilities across Japan between August 2014 and January 2015. Measurements were conducted over several weeks at wastewater purification facilities for swine farms： two in Chiba prefecture （East Japan）, two in Okayama prefecture （West Japan）, and one in Saga （Southern Japan）. Taking several environmental fluctuations into account, we collected measurement data continuously day and night, during both high-temperature and low-temperature periods. The results indicated that CH4 and N20 emission factors were 0.91% （kgCHa·kg volatile solids^-1） and 2.87% （g N2O-N·kg total N^-1）, respectively. Ammonia emissions were negligible in all of the measurements from the wastewater facilities. The N20 emission factor calculated under this experiment was low compared to our previous finding （5.0%; g N2O-N·kg N^-1） in a laboratory experiment. In contrast, the CH4 emission factor calculated herein was rather high compared to the laboratory measurements. There was great variation in daily GHG emission factors measured in the actual wastewater treatment facilities. In particular, the N2O emission rate was affected by several environmental conditions at each facility location, as well as by the management of the wastewater treatment.

In many tissues, trace metals such as iron(Fe), zinc(Zn), and copper(Cu) are important for various physiological functions such as immune function, cell division, and enzyme function. However, it has been shown in humans and experimental animal models that excessive amounts of these trace metals in the body can induce various diseases in the central nervous system, liver.

A high damping condition is easily obtained in Mn-(16-24) Cu-(4-6) Ni-2Fe (at. pct) alloys, when cooling rate is controlled after the solid solution treatment at 1173 K. It was observed that the temperature dependent changes of logarithmic decrement in 10 h cooled samples are sensitive to the alloy composition. As compared with water quenching treatment, controlled 10 h cooling improves T//N temperature of the alloys extensively by producing a Mn-enriched matrix portion in the alloys. Calculations suggest that the relative decreases of Cu and Ni content in the matrix portion be dominated by the Ni content in the original alloys, and therefore, the volume fraction of the Cu, Ni-enriched precipitates is estimated to be about 20% and 10% in the 4Ni and 6Ni alloys, respectively. As a result, the T//N temperature for each alloy, corresponding to the rising temperature of logarithmic decrement, has been related to the Cu, and Ni in the Mn-enriched matrix. The existence of left brace 110 right brace twinning boundaries is confirmed in the microstructure of both 4Ni and 6Ni alloys. However, the relative lattice strains, which the twinning boundaries act to accommodate, were found largely different in the two alloys. It is considered that boundaries with smaller orientation deviation can coordinate the external stresses easily by cyclic moving, and therefore, the broader damping peak which occurs in the 10 h cooled 6Ni alloy becomes feasible. Electron diffraction results also indicate possible formation of many sub-crystals in the matrix phase, which are relatively rotated on some invariant planes. Those sub-crystal boundaries might play some attenuation roles in the temperature range between T//N and room temperature. (Edited author abstract) 9 Refs.

The capability and reliability are crucial characteristics of mobile robots while navigating in complex environments. These robots are expected to perform many useful tasks which can improve the quality of life greatly. Robot localization and decisionmaking are the most important cognitive processes during navigation. However, most of these algorithms are not efficient and are challenging tasks while robots navigate through complex environments. In this paper,we propose a biologically inspired method for robot decision-making, based on rat’s brain signals. Rodents accurately and rapidly navigate in complex spaces by localizing themselves in reference to the surrounding environmental landmarks. Firstly, we analyzed the rats’ strategies while navigating in the complex Y-maze, and recorded local field potentials(LFPs), *** recorded LFPs were processed and different features were extracted which were used as the input in the artificial neural network(ANN) to predict the rat’s decision-making in each junction. The ANN performance was tested in a real robot and good performance is achieved. The implementation of our method on a real robot, demonstrates its abilities to imitate the rat’s decision-making and integrate the internal states with external sensors, in order to perform reliable navigation in complex maze.
