In this paper, we propose a novel way of combining multiple deep convolutional neural network (DCNN) architectures which work well for accurate video face identification by adopting a serial combination of 3D and 2D DCNNs. The proposed method first divides an input video sequence (to be recognized) into a number of sub-video sequences. The resulting sub-video sequences are used as input to the 3D DCNN so as to obtain the class-confidence scores for a given input video sequence by considering both temporal and spatial face feature characteristics of input video sequence. The class-confidence scores obtained from corresponding sub-video sequences is combined by forming our proposed class-confidence matrix. The resulting class-confidence matrix is then used as an input for learning 2D DCNN learning which is serially linked to 3D DCNN. Finally, fine-tuned, serially combined DCNN framework is applied for recognizing the identity present in a given test video sequence. To verify the effectiveness of our proposed method, extensive and comparative experiments have been conducted to evaluate our method on COX face databases with their standard face identification protocols. Experimental results showed that our method can achieve better or comparable identification rate compared to other state-of-the-art video FR methods.

This study was undertaken to identify the levels and affecting factors of the maternal role attainment(MRA) in the primipara during the postpartum period. The healthy ninety primiparous from the one university hospital and two local clinics in KwangJu city were selected and two Semantic Differential Scales (SD-Myself as Mothers, SD-My Baby) and the Pharis Self Confidence Scale were used in this study. Questionnaires were distributed at the 3rd days and the 4-6 weeks of the primiparous not showing any complication after normal delivery. The data collected were analysed statistically using t-test, Pearson's Product Moment Correlation Coefficient and ANOVA. The results obtained were summarized as follows; 1) On the 3rd day after the delivery, the scores of SD-myself as mother, SD-baby and Pharis Self Confidence were 70.6 points, 73.6 points and 78.6 points, respectively, showing the low level of MRA. 2) On the 4-6 weeks after delivery, the score of SD-myself as mother, SD-baby and Pharis Self Confidence were 72.8 points, 77.9 points, and 86.9 points, respectively, indicating the moderate level of MRA. 3) The mean scores of the SD scale and the Pharis Self Confidence during the postpartum periods were higher than those of the 3rd days, showing the SD-myself as mother (t=-2.09, P<.05), SD-baby(t=-4.12, P<.001), Pharis Self Confidence(t=-6.59, P<.001), respectively. 4) Positive correlations (r=.24$\sim$.69) were shown in the concepts related to the MRA and the cognitive-motor skill components and cognitive-affective skill components of the MRA became harmonious over time. 5) The relationships between the score of the MRA and the demographic and obstetric variables were as follows ; a) the score of the MRA in the twenties was higher than those of the thirties. b) the group with higher educational background showed higher MRA socres than the group with lower one. c) those who wanted pregnancy sustenance had higher MRA scores than those who did not. d) the group that did think of festus-feature represented higher MRA scores than those who did not. e) the group of mothers who have the daughters showed higher MRA scores than those who have boys. It can be concluded from the results that the MRA in the primiparous increased gradually, and that the cognitive-motor skills and cognitive-affective skills became harmonious over time. The level of the MRA was affected partly by the mothers general, obstetrical variables. Following suggestion were made oil the basis of the present study ; a) The longitudinal study on the MRA is needed. b) Multivariate analyses should be done for the identification of the factors influcening on the MRA. c) Education program for primiparous mother should be designed and developed to improve the MRA.

Purpose: Sudden unexplained infant death (SUID) is a major contributor to infant mortality, and pediatric nurses have the responsibility to educate parents on SUID-reducing strategies. This study was conducted to measure pediatric nurses' knowledge of SUID-related safe sleep practices (K-SSSP) and infant cardiopulmonary resuscitation (K-ICPR). Methods: In total, 136 pediatric nurses were administered a survey including K-SSSP (13 items), K-ICPR (5 items), confidence in K-SSSP education (1 item; 5 points), and other factors relating to SUID experiences or education. Results: The correct answer rates of the K-SSSP and K-ICPR were 62.6% and 62.5%, retrospectively. The mean score for confidence in K-SSSP education was 2.6±0.9. Only 18 nurses (13.2%) responded that they educated parents on the content of the K-SSSP, while 76 nurses had received education on SUID. Positive relationships were observed between K-SSSP scores and higher education, between K-ICPR scores and having own child(ren) and clinical experience, and between confidence in K-SSSP education and higher education or having one's own child(ren). Nurses caring for newborns performed more SUID education than nurses working in other units. Conclusion: There is a profound need to implement a systemic educational program on SUID and strategies to reduce SUID for pediatric nurses.

Background: The requirements for postural and motor control in backward walking training (BWT) may improve balance and walking speed in patients with acute stroke. The aim of this study was to analyze the effect of BWT on balance, balance confidence, and fall efficacy in this population. Design: Randomized controlled pilot trial. Methods: This study included 14 subjects with acute stroke (onset of illness less than one month). They were randomly allocated to a BWT (n=7) or forward walking training (n=7) group and observed five times in a week for a period of two weeks. Measurements were taken before and after the experiment using the Berg balance scale (BBS), Activities-specific balance confidence scale (ABC), and Fall efficacy scale (FES). Results: The BBS, ABC and FES scores obtained in both groups after the experiment were significantly higher than those before the experiment (p<0.05). In addition, the BBS, ABC, and FES scores in the experimental group were significantly higher than those in the control group (p<0.05). Conclusion: These findings indicate that BWT improved balance and balance confidence and decreased the risks of fall in patients with acute stroke. Further study is needed to better understand the effects of backward walking in acute stroke patients.

Purpose: The purpose of this study was to investigate perceptions of fatherhood among fathers of high-risk neonates and their confidence regarding neonatal care. Methods: A study was conducted of 100 fathers whose neonates had been admitted to a neonatal intensive care unit (NICU) for at least 48 hours. Perceptions of fatherhood, neonatal characteristics, and fathers' confidence regarding neonatal care were measured using a self-reported questionnaire. The survey took approximately 10 minutes to complete and was completed anonymously. The factors that affected fathers' confidence regarding neonatal care were analyzed using multiple regression. Results: The scores for positive and negative perceptions of fatherhood were relatively high at 4.27 and 3.42 out of 5 points, respectively. A positive perception of fatherhood was found to influence fathers' confidence regarding neonatal care. Conclusion: NICU nurses should encourage fathers to effectively perform their parenting roles by implementing educational programs and interventions to promote positive perceptions of fatherhood and fathers' confidence regarding neonatal care after discharge.

This study examined the clothing behavior in terms of creativity, individuality and conformity. The subjects were 317 boys(mean age: 18) and 312 girls(mean age: 18) in third grade of high school, in which were situated at north and south part of Han-River in Seoul. They were administered with the following questionnaires to measure the attitudinal and behavioral conformity, creativity, individuality, clothing conformity, clothing nonconformity, clothing confidence, aesthetic sense, clothing importance, fashionability. Results indicated that (1) high school students who have high creativity showed higher scores in clothing nonconformity, clothing confidence, aesthetic sense, clothing importance than those who have low creativity. But there were no significant differences between two groups in clothing conformity and fashionability(p<0.001). (2) High school students who have high individuality showed higher scores in clothing conformity clothing, nonconformity, clothing confidence, aesthetic sense, clothing importance and fashionability than those who have low individuality(p<0.001). (3) Students who have low attitudinal conformity showed higher scores in clothing nonconformity, clothing confidence and aesthetic sense(p<0.001) and lower score in information and norm specific clothing confirmity(p<0.05) than those who have high attitudinal conformity. And those who have high behavioral conformity showed higher score in clothing confirmity than those who have low behavioral confirmity(p<0.05). From these findings, we could find that the importance of creativity and individuality was greater than that of conformity in clothing behavior. These results were discussed and following studies were suggested.
