Purpose: This study was performed to investigate the quantities of three neo-maternal exposures; visiting frequency, auditory contact and physical contact, and to examine the relationship between the quantities of each exposure and maternal attachment, maternal self-esteem and postpartum depression in 40 mothers of NICU babies during the first week in the NICU. Method: Each neo-maternal exposure was counted at every mother's visit to the newborn and maternal attachment, maternal self-esteem and postpartum depression were measured using the maternal attachment inventory, the maternal self-report inventory and Edinburgh Postpartum Depression Scale (EPDS) on the first and seventh day in the NICU. Result: The Mean of each neo-maternal exposure was 8.77(2.81) for the visiting frequency, 5.82(3.66) for the auditory contact and 5.60(2.89) for the physical contact during 7 days in the NICU. No significant changes were found in the scores of maternal attachment, maternal self-esteem and postpartum depression between the first and the seventh day in the NICU. The quantities of neo-maternal exposures were positively related to the scores of maternal attachment and maternal self-esteem but not related to postpartum depression. Conclusion: The results of the study suggest the lack of early neo-maternal exposure in cases of NICU hospitalization negate its beneficial effects on maternal psychological well-being in increasing maternal attachment and self-esteem. More efforts are neededfor the neo-maternal interaction and the reevaluation of NICU visitation hours in order to promote maternal-infant interaction.

Fast File System(FFS) utilizes large disk bandwidth to improve the write performance of large files. One way to improve the performance is to write multiple blocks of a large file at a single disk I/O through the disk bandwidth. However, rather than disk bandwidth, the performance of small file writes is limited by disk access times significantly impacted by disk movements such as disk seek and rotation because FFS writes each of small files at a single disk write. We propose CW-FFS (Co-Writing Fast File System) to improve the write performance of small files by minimizing the disk movements that are needed to write small files to disks. Its key technique called co-writing scheme is to dynamically collect multiple small files named by a given directory and then write them at a single disk I/O to contiguous disk locations. Co-writing several small files at a single disk I/O reduces multiple disk movements that are needed for small file writes to one single disk movement, thus increasing the overall write performance of write-intensive applications. Furthermore, a file allocation scheme is introduced to prevent co-writing scheme from having a negative impact on disk spatial locality of small files named by a given directory. The measurement of our technique implemented in the OpenBSD 4.0 shows that CW-FFS increases the performance of small file writes over FFS in the range from 5 to 35% in the Postmark benchmark.

Purpose: The aim of this study was to examine the effects of systematic information on maternal attachment, parenting stress and maternal confidence of mothers of premature infants. Methods: Using a non-equivalent control group pre-post quasi-experimental design, 42 participants were assigned to one of two groups, an experimental group (n=20), which received systematic information; and a control (n=22), which received the usual discharge education. Prior to the intervention, baseline data were collected (pretest) and then the systematic information was provided four times for the experimental group. Maternal attachment, parenting stress and maternal confidence were measured. Data were collected three times: Seven to 10 days prior to discharge, day of discharge, and two weeks after discharge. Results: Mothers in the experimental group had significantly higher scores in maternal attachment (F=6.16, p=.005), lower parenting stress scores (F=5.56, p=.004), and higher scores for maternal confidence (F=16.50, p<.001) than mothers in the control group. These tendencies were progressively enhanced even two weeks after discharge from the hospital. Conclusion: The results indicate that provision of systematic information to mothers with premature infants is an effective intervention to enhance mothers' maternal attachment, decrease parenting stress, and enhance maternal confidence.
