EFFECTS OF FRUCTO-OLIGOSACCHARIDES ON MILK-YIELD AND MILK-COMPONENTS OF DAIRY COWS
Kobayashi, S.,Eida, T. Asian Australasian Association of Animal Productio 1990 Animal Bioscience Vol.3 No.1
Fructo-oligosaccharides are found in many plants, such as onion, burdock and wheat. They are not well hydrolyzed by digestive enzymes in animals, but are peculiarly assimilated by Bifidobacterium and some useful bacteria. In our previous experiment (Kobayashi et al., 1987) it was suggested that they were effective in decreasing energy loss in the metabolism of dairy calves. In the present study, the effects of fructo-oligosaccharides on body weight, milk-yield and milk-components (fat, protein and solids-not-fat) were investigated in dairy cows. Lactating cows were fed a standard diet containing fructoligo saccharides at 18.70g, 9.35g and 0.0g (control) per 100kg body weight, day for three weeks. Neither treatments significantly affected any of the parameters examined. The fructo-oligosaccharides were assumed to be hydrolyzed by rumen microorganisms and hardly to affect the bacterium florae in the intestines of the lactating cows.
Search for sub-GeV dark matter by annual modulation using XMASS-I detector
Kobayashi, M.,Abe, K.,Hiraide, K.,Ichimura, K.,Kishimoto, Y.,Kobayashi, K.,Moriyama, S.,Nakahata, M.,Ogawa, H.,Sato, K.,Sekiya, H.,Suzuki, T.,Takeda, A.,Tasaka, S.,Yamashita, M.,Yang, B.S.,Kim, N.Y.,K North-Holland Pub. Co 2019 Physics letters. Section B Vol.795 No.-
<P><B>Abstract</B></P> <P>A search for dark matter (DM) with mass in the sub-GeV region (0.32–1 GeV) was conducted by looking for an annual modulation signal in XMASS, a single-phase liquid xenon detector. Inelastic nuclear scattering accompanied by bremsstrahlung emission was used to search down to an electron equivalent energy of 1 keV. The data used had a live time of 2.8 years (3.5 years in calendar time), resulting in a total exposure of 2.38 ton-years. No significant modulation signal was observed and 90% confidence level upper limits of 1.6 × <SUP> 10 − 33 </SUP> cm<SUP>2</SUP> at 0.5 GeV was set for the DM-nucleon cross section. This is the first experimental result of a search for DM mediated by the bremsstrahlung effect. In addition, a search for DM with mass in the multi-GeV region (4–20 GeV) was conducted with a lower energy threshold than previous analysis of XMASS. Elastic nuclear scattering was used to search down to a nuclear recoil equivalent energy of 2.3 keV, and upper limits of 2.9 × <SUP> 10 − 42 </SUP> cm<SUP>2</SUP> at 8 GeV was obtained.</P>
Examining the Effects of Metacognitive Instruction in Oral Communication for EFL Learners
Ayako Kobayashi 아시아영어교육학회 2020 The Journal of Asia TEFL Vol.17 No.2
This study investigated the effects of metacognitive instruction in oral communication for EFL learners over a semester. Participants (N = 58) were sampled from four oral communication classes in a private university in the western part of Japan where the researcher had been working as an English instructor. They were freshmen whose majors were not English. The treatment group (n = 28) received metacognitive instruction in oral communication (i.e., they were taught how to improve oral communication skills and how to become more autonomous learners through metacognitive processes as well as activities such as planning, monitoring, and reflecting). The contrast group (n = 30), taught by the same teacher, did not receive metacognitive instruction although they used the same textbooks and materials and had more time for interaction in English. Results of the questionnaire (SRLQ, the Self-Regulated Learning in Oral Communication Questionnaire, Kobayashi, 2016a) showed that students in the treatment group became more self-regulated learners. Moreover, it was found that the treatment group made greater gains in interactional competence, regulation of cognition, cognitive strategies and interaction strategies. Furthermore, it was verified that learners with low interactional competence in the treatment group benefited the most from such metacognitive instruction.

It is necessary to shed light on difficulties faced by parents in the event of a disaster We studied that was to shed light on the difficulties faced by the parents of disabled children in the event of a disaster. The results showed that “home" was seleded by the highest number of respondents as shelter life place, followed by "car". On the other hand, number of users of "regional evacuation center" was 1/3 rd of that of “ home 씨 and around 2/3 rd of that of “car. Establis hment of such evacuation centers with much beUer support facilities compared to ordinary evacuation centers to ensure that disabled children , disabled people and their family need not live at home or in car feeling unsecured and unsafe, is extremely beneficial ‘

Ferroelectric memory devices are expected for low-power and high-speed memory applications. HfO 2 -based fer- roelectric is attracting attention for its CMOS-compatibility and high scalability. Mesoscopic-scale grains, of which size is almost comparable to device size, are formed in HfO 2 -based ferroelectric poly-crystalline thin films, which largely influences electrical characteristics in memory devices. It is important to study the impact of mesoscopic-scale grain formation on the electrical characteristics. In this work, first, we have studied the thickness dependence of the polarization switching kinetics in HfO 2 -based ferroelectric. While static low-frequency polarization is comparable for different thickness, dynamic polarization switching speed is slower in thin Hf 0.5 Zr 0.5 O 2 (HZO) capacitors. Based on the analysis using the NLS model and physical characterization, thinner HZO contains smaller grains with orientation non-uniformity and more grain boundaries than thicker HZO, which can impede macroscopic polarization switching. We have also theoretically and experimentally studied the polar-axis alignment of a HfO 2 -based ferroelectric thin film. While in-plane polar orientation is stable in as-grown HZO, out-of-plane polarization can be dominant by applying electric field, which indicates the transition from in-plane polar to out-of-plane polar orientation in the ferroelectric phase grains. This is confirmed by calculating kinetic pathway using ab-initio calculation.
