Studies of cry characteristics in the newborn infant were aimed to determine if cry analysis could be succesful in the early detection of the infant at risk for developmental difficulties. Crying presupposes functioning of the respiratory, laryngeal and supralaryngeal muscles. The nervous system controls the capacity, stability, and co-ordination of the movements in these muscles. Hence, the cry provides information about how the Nervous System is functioning. 3 patients(down syndrome, cornelia de lange syndrome, Patent ductus arteriosus) were assessed through a Computerized Speech Lab (CSL). Tests had been chosen to assess Fundamental frequency(mean, maximum, minimum values), Melody contour, NHR, Energy. We compared the data from patients and healthy volunteer. Variations in cry characteristics were documented in a number of medical abnormalities.

The combined impact of maternal depression, parenting stress, infant cry, and infant temperament on family functions was examined. The sample included 257 mothers in the near communities. Questionnaires completed by the mothers who had 0-36 month old children were used to measure depressive symptoms in mothers, infant cry, infant temperament, parenting stress, and family function. Maternal depression, parenting stress, infant crying and infant temperament had negative influence on family adaptability and family cohesion. Mother's depression had negative effect particularly on infant cry. Infant cry had positive effect on infant temperament. Infant temperament had high direct effect on parenting stress. As a result, it had negative influence on family function.

Purpose: The purpose of this study was to test the efficacy of treating the pain among newborn infants associated with a medical procedure with sucrose with regard to overall physiological and behavioral stability. Methods: 103 newborn infants were enrolled in this study. The control group (n=63) did not receive any treatment. The experimental group (n=40) received 2 mL of 24% sucrose solution two minutes before a routine heel stick. The pain was assessed by measurements of physiological changes [e.g. pulse rate, oxygen saturation, salivary cortisol (hydrocortisone)] and behavioral changes [e.g. crying time, and the neonatal infant pain scale (NIPS) for neonates]. Results: There were no differences among the groups with respect to physiological changes associated with the pain from the procedure. However, there were significant group differences in behavioral changes to the pain. In the control group, the median crying time was 13 seconds, while in the experimental group, the median crying time was 3.5 seconds ($P$=.000). In the control group the median NIPS score was 4, while in the experimental group the median NIPS score was 2 ($P$=.000). Conclusions: These findings suggest that sucrose can be an effective method for the management of stress responses in infants with regard to behavior. However, this treatment had no significant physiological effects.

영아는 비언어적 의사 소통 방식인 울음이라는 수단을 사용한다[1]. 하지만 영아의 울음소리를 파악하는 것에는 어려움이 따른다. 영아의 울음소리를 해석하기 위해 많은 연구가 진행되었다[2,3]. 이에 본 논문에서는 다양한 음성 데이터 증강을 통한 3D 특징 벡터를 이용한 영아의 울음소리 분류를 제안한다. 연구에서는 총 5개의 클래스 복통, 하품, 불편함, 배고픔, 피곤함(belly pain, burping, discomfort, hungry, tired)로 분류된 데이터 세트를 사용한다. 데이터들은 5가지 기법(Pitch, Tempo, Shift, Mixup-noise, CutMix)을 사용하여 증강한다. 증강 기법 중에서 Tempo, Shift, CutMix 기법을 적용하였을 때 성능의 향상을 보여주었다. 최종적으로 우수한 데이터 증강 기법들을 동시 적용한 결과 단일 특징 벡터와 오리지널 데이터를 사용한 모델보다 17.75%의 성능 향상을 도출하였다.

언어를 통한 의사 전달 능력이 없거나 뒤지는 소아들은 통상 울음으로서 자신의 상태를 나타낸다. 이 중 중요한 것이 바로 건강 상태를 나타내는 것인데 언어 전달 능력이 없는 소아들의 질병은 진단 시기를 놓치거나 정확한 진단 결과를 내리기 어려운 문제가 존재한다. 이를 위해 본 연구에서는 소아의 얼굴 색상 및 울음소리를 분석하여 질환 유무를 판단해 내는 시스템을 개발하고자 한다. 특히 본 논문에서는 얼굴 영역에 대한 추출 및 색상 분석과 울음소리의 특징 추출을 통해 소아의 심장 관련 질환에 대한 진단을 행하고자 한다. 각각의 생체 신호학적 분석 요소를 통해 정상적인 소아와 다른 부위의 질환을 앓고 있는 소아, 그리고 심장 질환을 앓고 있는 소아에 대한 집단별 비교, 분석을 행하고 이를 바탕으로 심장 질환 진단 방법을 제안하고자 한다. 또한 실험을 통해 소아 심장 질환에 대한 유의성을 추출하고 이를 기반으로 진단의 정확성 및 객관적 지표를 마련하고자 한다.

The purpose of this study is to investigate the reasons of Object Attachment Occurrence in infant and the meanings of it in his early development. For this purpose, the following hypotheses were supposed. 1. Infant's object Attachment will be a substitutional for mother attachment when he has opportunities to his mother during his first years. 2. Infant's Object Attachment will not impede the infant's normal development. In order to test this hypotheses 28 mothers whose infants show or have shown this phenomenon and 28 mothers whose infants show or have shown this phenomenon and 28 mothers whose infants do not show this one were interviewed about their child rearing practice and attitude. They were selected by the random sampling method from 310 household wives living at a delux Apt. in Seoul. The results obtained in this study are as follow ; 1. The less opportunities infant has for 1) his mother's breast feeding 2) having physical contact with his mother 3) spending time with his mother 4) receiving prompt response from his mother to his crying, the more he is apt to show this phenomenon. And infant whose first main attachment figure is not his mother also shows the same apt. 2. There was no difference between two groups in intelligence and personality. So it can be concluded that infant's Object Attachment is a substitutional phenomenon for mother attachment in the mother during his first years, and it does not impede infant's normal development.

Infants express their physical and emotional needs to the outside world mainly through crying. However, most of parents find it challenging to understand the reason behind their babies' cries. Failure to correctly understand the cause of a baby' cry and take appropriate actions can affect the cognitive and motor development of newborns undergoing rapid brain development. In this paper, we propose an infant cry recognition system based on deep transfer learning to help parents identify crying babies' needs the same way a specialist would. The proposed system works by transforming the waveform of the cry signal into log-mel spectrogram, then uses the VGGish model pre-trained on AudioSet to extract a 128-dimensional feature vector from the spectrogram. Finally, a softmax function is used to classify the extracted feature vector and recognize the corresponding type of cry. The experimental results show that our method achieves a good performance exceeding 0.96 in precision and recall, and f1-score.

Infants communicate their feelings and needs to the outside world through non-verbal methods such as crying and displaying diverse facial expressions. However, inexperienced parents tend to decode these non-verbal messages incorrectly and take inappropriate actions, which might affect the bonding they build with their babies and the cognitive development of the newborns. In this paper, we propose an aural-visual two-stream based infant cry recognition system to help parents comprehend the feelings and needs of crying babies. The proposed system first extracts the features from the pre-processed audio and video data by using the VGGish model and 3D-CNN model respectively, fuses the extracted features using a fully connected layer, and finally applies a SoftMax function to classify the fused features and recognize the corresponding type of cry. The experimental results show that the proposed system classification exceeds 0.92 in F1-score, which is 0.08 and 0.10 higher than the single-stream aural model and single-stream visual model.

Purpose: The purpose of this paper is to evaluate the efficacy of a lactose- reduced synbiotic partial whey hydrolysate in formula fed infants presenting with colic and the impact of this dietary intervention in mean crying time and quality of life. Methods: Forty infants with infantile colic were treated during one month with parental reassurance and the intervention formula (partial whey hydrolysate, reduced lactose, Bifidobacterium lactis BB12 and galacto-oligosaccharides) and were compared to a control group of 20 infants with infantile colic treated with parental reassurance and a standard infant formula. Parents completed a quality of life (QoL) questionnaire assessing the burden of infantile colic. Wilcoxon test, t-test and Mann-Whitney test were used to compare QoL scores before and after intervention as well as between the intervention and control group. Results: At inclusion, duration of crying did not differ between both groups. Crying duration decreased with 2.7 hours (from 3.2 to 0.5 hours) in the intervention group while duration of crying decreased only with 1.2 hours in the control group (p<0.001). Stool composition became looser in the intervention group, but defecation frequency did not change. The median scores of the QoL questionnaire improved significantly in the intervention group for all parameters. In the control group, parameters improved significantly also but not for the parent-child and social interaction. The score changes were significantly greater in the intervention than in the control group. Conclusion: The intervention formula (partial whey hydrolysate, synbiotic, reduced lactose) significantly reduced the duration of crying and improved QoL of the parents and infants.
