The aim of this study was to investigate the effectiveness of the Japanese Infant Mental Health Program (JIMHP) for preterm mother–infant dyads until the infants reached 12 months of corrected age. Mothers in the JIMHP group (n = 26) received one hospital visit in addition to standard care in the Growing Care Unit (GCU) and five home visits based on the principles of infant mental health (IMH) after discharge from the hospital, until the infant reached 12 months of corrected age. In contrast, mothers in the control program group (n = 40) received standard care in the GCU and three conventional home visits during the same period. The dyads were then compared across groups, revealing that the JIMHP dyads showed less maternal depressive symptoms, better maternal interaction, increased social support by medical workers and healthcare professionals, a high persistence rate for attending the program, and a more positive perception toward the program (p < .05). However, there were no significant differences in the impact of parenting stress or in child development. These results are discussed in terms of their significance and the practical/clinical availability of IMH principles and the JIMHP as a new support model for preterm infants in Japan. 相似文献

The atomic arrangements of short-range order (SRO) in two Al-rich γ-TiAl alloys with 62.5 and 60.0at.%Al respectively have been investigated by high-resolution transmission electron microscopy with image processing. For both alloys, SRO structures are formed in Ti-rich (002) layers of the L10 ordered γ-TiAl matrix, in the course of the phase transformation from the Al5 Ti3 long-period superstructure phase at lower temperatures to the h-Al2 Ti phase at higher temperatures. The SRO structures are composed of three types of ordered cluster: Ti4 Al type (square shaped), Ti3 Al type (fat rhombus shaped) and Ti2 Al type (lean rhombus shaped). The ordered clusters form local microdomains of the Al5 Ti3 and Al3 Ti2 superstructures in addition to the Al5 Ti3 and h-Al2 Ti superstructures, by different methods of tiling the ordered clusters. Such ordered clusters or microdomains tend to be in contact with each other through common {310) boundaries. This results in peculiar diffuse streaks in diffraction connecting intensity maxima arising from the long-period superstructures. 相似文献

Wild-caught jungle crows (n = 20) were trained to discriminate between color stimuli in a two-alternative discrimination task. Next, crows were tested
for long-term memory after 1-, 2-, 3-, 6-, and 10-month retention intervals. This preliminary study showed that jungle crows
learn the task and reach a discrimination criterion (80% or more correct choices in two consecutive sessions of ten trials)
in a few trials, and some even in a single session. Most, if not all, crows successfully remembered the constantly reinforced
visual stimulus during training after all retention intervals. These results suggest that jungle crows have a high retention
capacity for learned information, at least after a 10-month retention interval and make no or very few errors. This study
is the first to show long-term memory capacity of color stimuli in corvids following a brief training that memory rather than
rehearsal was apparent. Memory of visual color information is vital for exploitation of biological resources in crows. We
suspect that jungle crows could remember the learned color discrimination task even after a much longer retention interval. 相似文献

Summary The present investigation was designed to examine the most appropriate duration of instantaneous loudness and to find out the relationship between overall loudness and instantaneous loudness using 20-min road traffic noise. Instantaneous loudness was judged using the method of continuous judgment by category. The results suggest that instantaneous loudness is determined by the sound energy averaged during the 2.5-s period preceding each judgment, the duration of which seems to reflect the psychological present. It was also found that overall loudess is not an average of the instantaneous loudness of every moment, but that it is based on the instantaneous loudness above a certain level. 相似文献

The present study was designed to investigate anchor effects on loudness judgments, using reaction time (RT) as an index of loudness. In Experiment 1, anchor effects were reexamined using verbal categories. Two kinds of anchor stimuli, 60- and 90-dB SPL 1,000-Hz pure tones, and four kinds of series stimuli, 60-, 70-, 80-, and 90-dB tones, were used. In this experiment, clear anchor effects were found just the same as in our previous experiment. Experiment 2 was conducted using RT as an index of loudness with stimulus conditions similar to those in Experiment 1. The same anchor effects could be seen in this experiment too. As RT is quite free from the limitations inevitably accompanying the verbal responses, it may be concluded that the anchor effects reflect the shift in perception. 相似文献

Physically continuous sounds do not always produce the subjective impression of legato. In the present study, the effect of temporal factors on the impression of smoothness of a sound stream was systematically investigated in relation to the dynamic characteristics of hearing. The results showed that decaying sounds, successively presented, were perceived as being marginally connected when the sounds physically overlapped, while steady-state sounds were perceived as being marginally connected when they were physically separated. It was also shown that judgments by the subjects agreed quite well with the effect intended by the pianist when the passage was given in different temporal interpretations. 相似文献
