Acute phase rehabilitation is an important treatment for improving the functional outcome of patients after stroke. The present cohort study analyzed the feasibility and safety of acute phase rehabilitation using the hybrid assistive limb robot suit in 22 patients, 7 males and 15 females (mean age 66.6 ± 17.7 years). Neurological deterioration, mortality, or other accidents were recorded as adverse events. Baseline characteristics of each patient were recorded at the first hybrid assistive limb rehabilitation. Hybrid assistive limb rehabilitation was conducted for 12.1 ± 7.0 days with the patients in stable condition. Acute phase hybrid assistive limb rehabilitation was performed a total of 84 times with no adverse events recorded except for orthostatic hypotension. Good functional outcomes were obtained in 14 patients. Orthostatic hypotension was observed during the first hybrid assistive limb rehabilitation in four patients, and was significantly associated with intracerebral hemorrhage (p = 0.007) and lower Brunnstrom stage (p = 0.033). Acute phase rehabilitation using the hybrid assistive limb suit is feasible and safe. Patients with intracerebral hemorrhage and lower Brunnstrom stage should be carefully monitored for orthostatic hypotension.

本研究では, 津波地震の発生原因が「断層面上のゆっくりとした断層破壊」と仮定して, それに伴う「ゆっくりとした海底面変動」が津波を引き起こす過程および伝播の特性を数値計算によって検討した.ライズタイムが100s程度であれば断層破壊の影響は無視でき, 静的変位から予想される津波と同程度の津波が発生する. また, ライズタイムが500sのゆっくりとした海底面変動でも水塊移動を引き起こし津波が発生することを示した. ただし, 津波の波高が小さくなり, 周期が長くなる点は従来の予測とは大きく異なる.本研究は, ゆっくりとした断層破壊による地震津波に対しても, 沖合観測によって早期に津波を検知できることを示唆している.

Direction of rupture propagation φ and fault length L for the 1994 Sanriku-Haruka-Oki earthquake are evaluated from the azimuthal dependence in duration of strong ground motion observed at eleven stations along the Pacific coast of Tohoku and Hokkaido region. After defining the strong motion duration D as the time interval between onset of S wave and 85% of cumulative power curve derived from 5 to 10Hz band-pass filtered accelerogram, the azimuthal dependence of D is examined. We find that D systematically shows directivity: D is the shortest at northern part of Tohoku and the longest at southern part of Tohoku and eastern edge of Hokkaido. By making use of the directivity on observed strong motion durations, we apply the method by IZUTANI and HIRASAWA (1987) to deducing φ and L together with VR/β, where VR and β are rupture velocity and S wave velocity. Assuming that rupture initiated from the epicenter determined by the Japan Meteorological Agency (JMA), we obtain L/VR=53, VR/β=0.62, and φ=W9°N (case 1). This result indicates that the rupture was headed toward northern part of Tohoku, and terminated near the western end of aftershock area. Detailed source-process inversion [for example, SATO et al. (1996)] suggests that main rupture nucleated near the center of aftershock area, corresponding to the epicenter determined by Harvard University. We redo the calculation assuming that the rupture initiated from the Harvard epicenter, then resulting in L/VR=28, VR/β=0.71, and φ=W18°N (case 2). This result also indicates that the rupture propagated toward northern part of Tohoku, and terminated at the western end of aftershock area. SATO et al. (1996) suggest that this earthquake consists of threestage rupture process: the first and the second sub-events corresponding to JMA and Harvard epicenter, respectively, and the third sub-event located near the western end of aftershock area at the distance of about 50km from Hachinohe city. The location where rupture terminated in both cases of this study is consistent with the location of the third sub-event, confirming that the rupture extended to the western end of aftershock area.

“Aseri” is a Japanese term referring to an emotional state of “being impatient” or “feeling time urgency” that is experienced in everyday life. This study explored how people in early adulthood experienced aseri in their daily lives. Interviews were conducted with twenty young adults who recalled events or situations involving aseri. Grounded theory was referred in collection and analysis of data. The results showed that aseri developed in situations where there were several competing thoughts. Regarding the process in which aseri changed, two patterns were found: (a) when aseri was strongly experienced in the short term, it settled down easily; (b) when aseri was felt mildly in the long term, it gradually became latent. The theme of latent aseri reflected the developmental tasks of early adulthood that were considered significant for the participants including developmental tasks typically achieved in adolescence that were put off until early adulthood. Implications for aseri and directions for further research are discussed.

The dynamics of the polyaromatic structures of black humic acids (HAs), which are presumably derived from charred materials, are of significant interest for the global carbon cycle. However, the details of those dynamics are not yet well understood. We investigated differences in the degree of darkness (A600/C values), isotopic ratios (δ13C, δ15N, and Δ14C values), and 13C NMR spectra of size-separated black HAs extracted from Japanese volcanic ash soils in order to estimate the variations in the polyaromatic structures of black HAs during ca. 100 years of natural reforestation of Japanese pampas grassland. For several hundred years, all the study sites were managed similarly as grassland by burning. Subsequently, their management differed: at site G (Miscanthus sinensis: C4 plant), maintenance as of the time of this study was still performed by mowing, while at sites P (Pinus densiflora: C3 plant) and Q (Quercus crispula: C3 plant), maintenance was discontinued ca. 30 and 100 years ago, respectively. Thus, the sites range from grassland (site G) to coniferous forest (site P) to broad-leaved forest (site Q). For all HA size fractions at all sites, we found that δ13C values correlate positively with δ15N values, although the gradients are much lower for fractions of small to medium molecular size than for fractions of medium to large molecular size (denoted as lower-size and higher-size fractions, respectively). Overall, for the lower-size fractions, the contribution ratio of C4-plant-derived carbon shows a significant positive correlation with A600/C values and a negative correlation with Δ14C values, and their aromatic characteristics are greater than those of higher-size fractions within the same black HA. Furthermore, the relative proportion of lower-size fractions decreases with reforestation, especially from site P to Q. The δ13C values for all size fractions are similar for sites G and P, but are relatively low for site Q. The aryl C contents of the lower-size fractions are lower and the O-alkyl C contents and the aliphaticity (alkyl C:O-alkyl ratio) are clearly higher for sites P and Q than for site G. These results strongly suggest that stimulation of HA biodegradation might be achievable by continuous input of new plant litter during reforestation, even for lower-size HA polyaromatic structures, despite the fact that lower-size HAs biodegrade more slowly than higher-size HAs.

講談社刊行雑誌『少年倶楽部』(のちに『少年クラブ』改称)は、発刊された1914(大正3)年から昭和戦前期にかけて、当時小学校高学年から中学生までの読者層の多くを"愛読者"として獲得することに成功した。彼らは立身出世による進学意識、勤勉かつ真面目であり国家に奉公できる少年像をメルクマールに、投書欄に集い次第に読者共同体を形成していった。戦後多くの少年の夢や希望を与えることを使命に、復刊を果たした。復刊されたが、投書欄の登場は発刊から数年を経てからであった。戦後の同誌は民主化政策の影響で投書内容も戦前のものとは異なり「学級新聞」や「日記」等が見られた。また誌面で仲間を求める内容のものも見られなかった。昭和30 年代中ごろより「テレビ」、「まんが」といったマス=メディアの影響を大きく受け、誌面構成に大きく波及した。後進の新興雑誌などと販売競争しながらも継続発行されたが、1962(昭和37)年にその役割を終えた。
