Young children's speech is compared to adult-to-adult speech and adult-to-child speech by measuring durations and variability of each segment in CVC words. The results demonstrate that child speech exhibits an inconsistent timing relationship between consonants and vowels within a word. In contrast, consonant and vowel durations in adult-to-adult speech and adult-to-child speech exhibit significant relationships across segments, despite variability of segments when speaking rate is decreased. The results suggest that temporal patterns of young children are quite different from those of adults, and provide some evidence for lack of motor control capability and great variance in articulatory coordination.

This research attempted to examine the effects of adult attachment which belongs to the psychological characteristics of the educare teachers on the behavior young children's adjustments through the educare teacher's self-efficacy and styles of discipline. To achieve this, a survey was conducted on 866 children aged 2-5 years attending 23 educare centers located in Seoul, the region of Gyeonggi and Gyeongsangbuk-do, and their 135 teachers in charge. The results of this research demonstrated that first, educare teachers' adult attachment had indirect effects on the young children's adjustments by the media of self-efficacy. Second, the educare teachers'adult attachment was found to have indirect effects on the young children's adjustments by the media of discipline styles. Third, the educare teachers' adult attachment was found to have effects on the young children's adjustments through self-efficacy and discipline styles. In conclusion, with regard to the effects of the educare teachers' adult attachment on the young children's adjustments the mediated effects of self-efficacy and discipline styles were confirmed. This research enables one to have an in-depth understanding of the process in which the educare teacher's psychological characteristics have important effects on the social and emotional development of young children and it is expected that it will become evidence data for realizing the need for developing practical educational programs regarding the character development and mental health of the educare teachers.

A difference in ethanol metabolism between premature and young adult rats was examined. Female SD rats, either 4wk or 12wk old, were injected with a single dose of ethanol (1.5g /kg) through jugular vein and the blood ethanol level was monitored for 300 min using a gas chromatographic method. Reduction of blood ethanol level per unit of time was less and the area under the blood concentration-time curve (AUC) was significantly greater in young adults compared to premature rats. Activity of hepatic alcohol dehydrogenase was not influenced by the age increase. Total cytochrome P-450, cytochrome $b_5$. or aminopyrine N-demethylation was not different between premature rats and young adult rats. However, p-nitrophenol hydroxylation and p-nitroanisole O-demethylation activities were significantly higher in premature rats. The relative liver weight was 45% greater in premature rats leading to an overall increase in ethanol metabolizing activity in these animals. The results indicate that the reduction in ethanol elimination in young adult rats appears to be mostly associated with the decrease in relative liver weight as the age of animals increases.

The purpose of this study was to investigate the effects of calcium intake levels on magnesium utilization in young and adult rats fed various levels of calcium(50, 100 or 200% of requirement) for 3 weeks. Feed intake, body weight gain, and feed efficiency ratios of the young group were significantly higher than those of the adult group. In calcium levels of tissues, serum calcium levels in young group were higher than in the adult group and kidney calcium levels in HCa(high-calcium group) were higher than in other groups. There was no significant difference in magnesium intake among age and diet groups. However, magnesium excretions through feces and urine in the adult group were higher than in the young group. Therefore, magnesium retention in the young group was higher than in the adult group. Especially in the young group, fecal magnesium excretion was increased with increasing levels of dietary calcium. Serum magnesium levels were lowest in YHCa(young 8t high-calcium) group, and there was no significant difference in liver and kidney levels among the calcium-diet groups. These results indicate that high calcium consumption promotes of fecal magnesium excretion and decreased magnesium retention rates in growing rats. Therefore, it is suggested that mineral interactions should be considered in the supplementation of dietary calcium intake for growth. (Korean J Nutrition 31(9) 1404-1410, 1998)

Background: The collection of ovaries from slaughterhouses is an important source of oocytes for in vitro embryo production. On the other hand, the physiological stage of slaughtered females varies and influences embryo production. Objectives: The study examined the in vitro efficiency of embryos and demi-embryos from young, non-pregnant adult, and pregnant adult ewes from a local slaughterhouse. Methods: One thousand three hundred ovaries were collected from August to October 2020. The recovered oocytes were matured, fertilized, and cultured at 5% CO2, 38.5℃, and 100% humidity. Embryo bisection was performed in 96 blastocysts (n = 32 per treatment). The demiembryo pairs were incubated for their reconstitution for 12 h. SAS was used for data analysis. Results: The number of oocytes collected from the experimental group of non-pregnant adult ewes was higher (p ≤ 0.007) than those collected from the group of pregnant adult ewes (2.67 ± 0.19 vs. 2.18 ± 0.15 oocytes/group, respectively). The blastocyst rate was higher (p ≤ 0.0001) in the non-pregnant adult group (36.39%) than in the young (17.96%). The ratio of demi-embryos that recovered the blastocoelic cavity was higher (p < 0.05) in the young group (81.25%) than in the pregnant adult group (59.38%). The diameter of the demi-embryos was higher (p < 0.05) in the non-pregnant adult group (186.54 ± 8.70 ㎛) than those in the young and pregnant adult groups. Conclusions: In conclusion, the in vitro embryo production efficiency was highest when using oocytes from non-pregnant adult ewes under the conditions of this study.

Purpose: This study aims to investigate the effects of atopic dermatitis on suicidal ideation, plans and attempts in young adult. Methods: Data are from the Sixth Korean National Health and Nutrition Examination Survey (KNHANES VI, 2013, 2015) in a sample of 2,983 respondents aged 19 to 39 years. Data were analyzed using Frequency, Percentage, $x^2$ test, Complex sample multivariate binary logistic regression analysis with SPSS version 18.0 software. Results: Firstly, factors affecting suicidal ideation are gender, education level, smoking, self-reported health status, asthma, depression and stress perception. Factors affecting suicidal plan are education level, self-reported health status, asthma and depression. Lastly, factors affecting suicidal attempt are gender, education level, smoking, self-reported health status, depression and stress perception. Compared to non-atopic group, the prevalence of suicidal ideation and plan of atopic group increased from odds ratio 2.14 to 2.48 and 1.90 to 2.50, respectively. Odds ratio for suicidal attempt was odds ratio 2.69 (10% error level). Conclusion: The results show that atopic dermatitis in young adult affects suicidal ideation, plans and attempts. Therefore, it is necessary to identify atopic patients who have suicidal thoughts and plans and develop an intervention program to prevent and manage suicide in young adult.

Vitamin $D_3$ up-regulated protein 1 (VDUP1) gene is known to be a novel member of early response genes as an oxidative stress mediator. To elucidate role of VDUP1 expression in neuronal injury, VDUP1 gene expression and histological change were tested in the spinal cords after traumatic spinal cord injury (SCI) in young and adult rats. VDUP1 transcript was detected weakly in a few cells in the spinal cords of control young and adult rats. VDUP1 transcript was increased in the contused spinal cords 1 day after SCI in both young and adult rats. VDUP1 transcript was decreased in the spinal cords 7 days after SCI in young rats. However, VDUP1 transcript was not decrease significantly 7 days in the spinal cords after SCI in adult rats. Cell damage in the spinal cords and hind limb dysfunction were more prominent 7 days after SCI in adult rats compared with that in young rats. These data show that VDUP1 may be involved in neurodegeneration after traumatic SCI.

The author studied on the dental arch widths and lengths and height of palates at 3 groups of dentition: mixed dentition, early permanent dentition, young adult, having normal occlusion and dentition. The models of the 336 maxillary and mandibular case, made from alginate-base hydrocolloid impressions were measured and analyzed statistically. The result as follows; 1. The upper intercanine width increased between the mixed dentition group and early permanent dentition group but there was no change in the young adult group in both sexes. The lower intercanine width increased between the mixed dentition group and early permanent dention group in the male. 2. The upper and lower 1st bimolar width increased slightly with age in the male but there was no change in the female. 3, The sex difference found in this study was one of absolute size, the female being slightly smaller than the male in the early permanent dentition group and young adult. 4. The arch length had no notable sexual differences and decreased between the mixed dentition group and early permanent dentition group. There was no change in the arch length in the young adult. 5. The height of palate increased gradually with age.
