Purpose: Breastfeeding is the best way to feed all infants, but not all infants can be (exclusively) breastfed. Cow's milk based infant formula is the second choice infant feeding. Methods: The safety of a new synbiotic infant formula, supplemented with Bifidobacterium lactis and fructo-oligosaccharides, with lactose and a whey/casein 60/40 protein ratio was tested in 280 infants during 3 months. Results: The median age of the infants at inclusion was 0.89 months. Weight evolution was in accordance with the World Health Organization growth charts for exclusive breastfed infants. The evolution of all anthropometric parameters (weight-for-length z score and body mass index-for-age z score) was within the normal range. The incidence of functional constipation (3.2%), daily regurgitation (10.9%), infantile crying and colic (10.5%) were all significantly lower than the reported median prevalence for a similar age according to literature (median value of 7.8% for functional constipation, 26.7% for regurgitation, 17.7% for infantile colic). Conclusion: The new synbiotic infant starter formula was safe, resulted in normal growth and was well tolerated. Functional gastro-intestinal manifestations (functional constipation, regurgitation and colic) were significantly lower than reported in literature. Synbiotics (Bifidobacterium lactis and fructo-oligosaccharides) in cow's milk based infant formula bring the second choice infant feeding, formula, closer to the golden standard, exclusive breastfeeding.

Let X and $X_t$ denote the lifetime and the residual life at age t, respectively. X is said to be a NBUL (new better than used in Laplace transform order) random variable if $X_t$ is smaller than X in Laplace order, i.e., $X_t{\leq}_{LT}X$. We propose a new test statistics for testing exponentiality versus NBUL class of life distribution. The tests by Hollender and Proschan (1975) and the generalized Hollender and Proschan test by Ains and Mitra (2011) are considered as special cases of the our of test statistics. Our proposed test statistics is simple, consistent and asymptotically normal. Efficiency and powers of the test statistics for some commonly used distributions in reliability are discussed. Finally, real examples are presented to illustrate the theoretical results.

Objective: The purpose of this study were to examine the growth pattern of weak children by measurement according to the five weak symptoms (respiratory, digestive, psycho-neurological, neuromotor, urogenital symptom). Five weak symptoms are common etiology of short stature in childhood and oriental medicine therapy is used as a treatment in short stature but the effects on height are not conclusive. Methods: This clinical study had been carried out with the 166 case (male 74, female 92) of the children aged 3 to 18 years old who visited in growth clinic of Pediatrics, Dongguk university Bundang Oriental Hospital. They were divided into 3 groups by age (3-10, 11-14, 15-18 years group) Five weak symptoms were studied to determine the association with growth stature among children by comparison with the growth stature of weak children group and normal group Results: The distribution of age showed the highest in 11-14 years(58.4%), followed by I 3-10 years (26.5%), over 15years(15%) in order. In case of male, the distribution of five weak symptoms showed the highest respiratory weak symptom(68.9%), followed by digestive(52.7%), psycho-neurological(43.2%), neuromotor(24.3%), urogenital weak symptom (143.5%) and digestive weak children's Height SDS were lower than normal children in all age groups and respiratory weak children's Height SDS were lower than normal children in age group of 3-10. In case of female, the distribution of five weak symptoms showed the highest digestive weak symptom(59.8%), followed by respiratory(52.5%), psycho-neurological(51.5%), neuromotor (35.9%), urogenital weak symptom (25%) and digestive weak children's Height SDS were lower than normal children in age group of 3-14. Other weak children Height SDS were no significant difference from normal group. Conclusions: From the above result, it was suggested that weak symptoms is cause in short stature. These data indicate that the height was correlated with respiratory, digestive weak symptom and a way to improve the weakness increased significantly height in children growth stature. Growth stature should be investigated as a new field of oriental medical treatment and more controlled, long term studies are required to classify benefits of Oriental medicine therapy in short stature.

The purpose of this study is to investigate the relationship between the characteristics of using new words, ability to use new words, and peer popularity among students with mild intellectual disabilities and general students of the age-matched group. A total of 8 students, 4 students with mild intellectual disabilities aged 14 to 16 years of age and 4 normal students in the age-matched group, were compared between groups using a nonparametric test. In the case of new words, 60 new words were selected through expert content validity among 301 new words, and then recognition and background information on the 60 new words were collected. As a result of the study, first, there was a significant difference in understanding of new words between the student group with mild intellectual disability and the general student group of the same age. Second, the correlation between the use of new words and the popularity of peers was compared for each group of students with mild intellectual disabilities and a group of general students of the same age as possible. Therefore, when providing vocabulary instruction for students with mild intellectual disabilities, it suggests that it is necessary to teach new vocabulary in order to increase their relationship with their peers and their popularity.

Many previous studies based on respiratory characteristics of Idiopathic Parkinson's Diseases (IPD) patients have not controlled related factors appropriately. Accordingly, these studies produced discordant results. Furthermore, there is currently a lack of studies that can provide precise explanations on the characteristics of respiration and phonation. This study included a total of 40 subjects: 20 mixed gender de novo IPD patients ranging in age from 50 to 80 (Hoehn & Yahr stage 1~3), and 20 normal subjects with similar matches for age and gender. All participants were controlled based on their gender, age, height, weight, vocal fold function, cognitive abilities, and depression factors. K-MMSE (Korean-Mini Mental State Examination), nVHI-10 (new Voice Handicap Index), and KGDS (Korean Form of Geriatric Depression Scale) were evaluated to select this study subjects. In order to compare respiratory functions between the two groups, FVC, FEV1, and FEV1/FVC were measured using microQuark, a PC-based spirometer. CSL was used by measure MPT and PAS was used to measure MFR. To investigate the characteristics of phonation ability, CSL was used to measure jitter and shimmer, while PAS was used to measure Psub. In order to compare the respiratory function averages and phonation ability between the two groups, statistical analysis was conducted using SPSS (version 12.0). The results of this study showed that most de novo IPD patients were included in the normal average range of respiratory and phonatory ability. But the respiratory and phonatory ability of de novo IPD patients showed lower tendency as compared with the normal group. When the average of respiratory and phonatory ability among the gender was compared, the difference of males was greater than the difference of females.
