日本統治期朝鮮における学校観形成の一側面 -普通学校修身書にみる学校の描写と指導の変遷-

本稿は、日本統治期朝鮮の普通学校修身書に描かれた「学校」とそれに関連する指導内容に着目することにより、日本が朝鮮で図った学校観形成の一側面について検討するものである。1910年の「併合」以降、朝鮮半島での日本による社会的、文化的、経済的な施策の多くは、おもにその制度的外形と数量的な側面から朝鮮の近代化を進める「発展・開発」政策としての「正当性」を帯びたものであった。当時の金融制度の整備や土地調査事業の実施、工業化、鉄道や港湾、ダムの建設・整備等に対する積極的な見方は、そうした「正当性」を文字通りに評価するものであり、現在でも日本の朝鮮統治を肯定する「植民地近代化論」に散見されるものである。journal articl

Triaxial accelerometer based azimuth estimator for horizontal axis wind turbines

One of the elements that receives the greatest stresses is the main shaft. Its damage is directly related to the cyclical nature of its rotational motion. However, the vast majority of horizontal axis wind turbines (HAWT) do not have sensors to measure the main-shaft angular position (azimuth), or they are not always easily accessible. Using a main-shaft placed single triaxial accelerometer for the estimation of the azimuth is proposed as a low intrusion approach that can be easily deployed in machines already in use. An approach using a tandem of two extended Kalman filters (calibration/prediction), aiming for a precise and robust estimation, is presented. The estimator is able to calibrate for accelerometer positional and orientation errors, as well as for bias drift. To simplify the burden of deployment, a simple procedure is proposed to determine the covariance matrices for a particular HAWT from those determined in a synthetic case. The proposed approach is analyzed using synthetic data, OpenFAST simulation of NREL-5MW HAWT. It outperforms the ATAN naive approach by an order of magnitude, showing errors smaller than 0.4o. The filter shows a good behavior, coherent with that of the synthetic setup, when tested on experimental data obtained from a 3MW HAWT.This work was funded by the “Convocatoria de ayudas a proyectos de I + D del Gobierno de Navarra” under the project Ref.

Ultra-low frequency multidirectional harvester for wind turbines

In this paper we propose, and demonstrate through a prototype, a completely novel device able to harvest mechanical energy from the multidirectional vibrations in a wind turbine, and convert it into electrical, to power autonomous sensors. The application is very challenging since vibrations are of ultra-low frequency, well below 1 Hz, with accelerations of tenths of cm/s2 (0.01 g), and the device must capture energy from the movement in any direction. According to our experiments, the device is capable to generate average powers around the milliwatt in the operation conditions of a wind turbine, which are enough for some very-low power sensor nodes, or at least to considerably extend the life-time of batteries. The device is based on the principle of moving (inertial) masses comprised of magnets in Hallbach arrays interacting with coils, and can work for movements on any direction of a plane. To the best of our knowledge, this is the first device specifically proposed for wind turbines and one of the few that work in such low frequencies, and capture energy from movements on any direction on a plane. Only three harvesters proposed in the literature, intended for distinct applications, can work at such low frequencies, and our device exhibits a better efficiency. Though comparisons with harvesters working in different contexts and, even using different conversion principles, is not completely fair, we make in this paper a comparison to the closest ones, resorting to two different figures of merit.This work has been supported by the Spanish Research Agency under grant AEI/FEDER, PID2019-107258RB-C32, and also by the Government of Navarre (Dpt. of Economic and Business Development) under grant 0011-1365-2021-000199.

ヒオウギガイのヘモリンパ液の酸塩基平衡に及ぼす大気暴露の影響

We investigated the oxygen and acid–base status of the noble scallop Mimachlamys nobilis during air exposure for 24 h. The hemolymph of noble scallop was collected from the adductor muscle, and O2 partial pressure (Po2 ), pH, CO2 partial pressure (Pco2 ), and bicarbonate ion concentration ([HCO3–]) were examined during air exposure. Hemolymph Po2 decreased from 69.5 torr (mean value) to 46.3 torr during air exposure for 6 h, and reached to 19.0 torr after 24 h. The hemolymph Po2 of air-exposed noble scallops decreased gradually and caused progressive hypoxemia by hypoventilation of the ctenidium. Air-exposed noble scallops showed a reduction in pH and elevation of Pco2 and [HCO3–] of the hemolymph. In air-exposed noble scallops, the hemolymph pH decreased from 7.460 to 7.045 at 6 h and to 6.348 at 24 h. The hemolymph Pco2 increased from 1.30 torr to 5.05 torr at 6 h and to 56.6 torr at 24 h during air exposure. The [HCO3–] increased from 1.26 mM/L to 1.88 mM/L at 6 h and to 4.19 mM/L at 24 h. From these results, in the first 6 h of air exposure, noble scallops mainly underwent respiratory acidosis by excess accumulation of CO2 due to hypoventilation. Meanwhile, after 24 h of air exposure, noble scallops showed mainly metabolic acidosis partially compensated by mobilized [HCO3–] from the shell.ヒオウギガイMimachlamys nobilisのヘモリンパ液の酸素分圧は，大気曝露前に69.5torr（平均値）を示したが，曝露6時間後に46.3 torr，24時間後に19.0 torrにまで減少した．ヘモリンパ液pHは曝露前に7.460を示したが，曝露6時間後に7.045，24時間後に6.348にまで低下した．ヘモリンパ液の二酸化炭素分圧は曝露前に1.30 torrを示したが，曝露6時間後に5.05 torr，24時間後に56.6 torrにまで増加した． 重炭酸イオン濃度は曝露前に1.26 mM / Lを示したが，曝露6時間後に1.88 mM / L，24時間後に4.19 mM / Lにまで増加した．これらの結果から，ヒオウギガイは大気に曝露されると進行性の低酸素血症を引き起こすとともに，二酸化炭素の過剰蓄積による呼吸性の酸性血症を示し，その後に部分代償性の代謝性酸性血症を呈することが明らかとなった．departmental bulletin pape
