This study compares speech rate, articulatory rate, and pause between the children with mild and moderate Speech Sound Disorder (SSD) who performed Sentence Repetition Tasks and the Typically Developing children (TD) of the same chronological age. The results showed that three groups are categorized in terms of speaking rate and articulatory rate. There is no difference between the two groups with SSD children, namely between the mild and moderate groups. However, there is a significant difference in their rate of speech and the articulatory rate between the two groups, such that the two groups with SSD are significantly slower than the TD group. The results also showed that there are no significant difference in the length and frequency of pause between the moderate group and the mild group. However, there is a substantial difference between them and the TD group. This study, provided the basic data for evaluating the speech rate of the children and implies that there are limitations in speech rate among the children with SSD.

The objective of this study was to investigate the influence of family-related factors and age-friendly environment on intergenerational interaction in middle-aged group and the older adult group. Based on the results, this study is to suggest countermeasures for decreasing intergenerational interaction with the population aging. This study analyzed 260 sample participants aged from 45 to 64 and 399 sample participants aged 64 and more, categorizing them into middle-aged group and the older adult group respectively. The sample participants were taken from '2014 Survey on the Aged Society' and had at least one adult child aged over 18 at the time of participation. In order to identify the relationship between five sub-dimensions related to family, age-friendly environment and intergenerational interaction within the family in two age groups, t-test and multiple regression analysis were used. As a result, both two family-related factors had positive correlation with intergenerational interaction within the family. However, affective solidarity showed a higher significance in the middle-aged group and familism showed a higher significance in the older adult group. Among the sub-dimensions related to age-friendly environment, only personal opinion on age integration showed significance in the older adult group. This study provides several implications from the results.

Objectives : The purpose of this study was to show the corelation between age-related muscular mass and the change of exercise, muscle mass and muscular strength by comparison of muscle strength. Methods : 39 volunteers of all the patients who come to Dangjin health center between May and June in 2009 were classified as group A and group B according to age. Demographic data of these two groups have been done a comparative analysis, using the t-test procedure and linear regression analysis. Results : The results and summarized as follows. 1. Demographic data of these two groups have been done a comparative analysis, using the t-test procedure. As a result the average exercise and the average pulse have a statistically significant difference according to age. 2. Each of average fat, muscle and muscular strength in these two groups have been done a omparative analysis, using the t-test procedure. As a result there is no statistically significant according to age. 3. According to the result analyzed by using linear regression analysis, age have a negative effect on muscle but there is no statistically meaningful. Exercising have a positive effect on muscle and there is statistically significant. 4. Age and Protein diet have a negative effect on Grip strength but there is no statistically significant Conclusions : From this result, it can be assumed that the amount of exercise is decreasing with age, which leads to lose some muscle mass.

Background: Nasal bone fractures are the most common type of facial bone fracture, but are under-studied in adults above 65 years of age. Therefore, we investigated the epidemiology and patterns of nasal bone fractures among older adults in comparison to different age groups. Methods: This retrospective study included 2,321 nasal bone fracture patients who underwent surgery at our hospital from January 2010 to December 2017. The patients were classified by age as preschoolers, school-age children, young and middle-aged adults, and the elderly. We performed pairwise comparisons between elderly patients and each other age group in terms of sex, cause of injury, and fracture type. Results: The 2,321 nasal bone fracture patients included 76 elderly patients (50 men [65.8%] and 26 women [34.2%]). In these patients, the two most common injury causes were falling or slipping down (n= 39; 51.3%) and road traffic accidents (n= 19; 25.0%). According to the Stranc and Robertson classification, the most common force vector was lateral, and plane 2 fractures with lateral forces predominated. Conclusion: The elderly showed similar patterns of nasal bone fractures to those observed in young and middle-aged adults, but significant differences from preschoolers (in the injury vector and plane of fracture) and from school-age children (in the sex ratio and plane of fracture). However, elderly patients presented significantly different epidemiological characteristics compared to the other three groups. Therefore, it is necessary to improve the quality of life of the elderly and prepare for the upcoming super-aged society by taking steps to reduce the incidence and severity of fractures. Possible options for doing so include strengthening individual-level safety factors and expanding the social safety net for the elderly.

In an attempt to take Comprehensive nursing care the author tested cognitive function and psychiatric disturbance produced by normal adults. Mini-mental state and simple reaction time were tested and general health questionnaire was conducted two hundred subjects. The data were analyzed statistically and the results follow: 1. The score of mini-mental state of the elderly group was less significant than that of the younger group in the tests of cognitive dysfunction. The score of MMS of the female group, the illiteracy group less significant than that of other groups in the test of cogntive dysfunction. 2. Reaction time of the elderly group was slower than that of the younger group. Reaction time of the female group was slower than that of the male group. Reaction time of the illiteracy group was the slowest & the unskilled group was slower than that of the other groups. 3. As a result of the results of psychiatric disturbance the score of general health questionnaire of the elderly group was significantly higher than that of the younger group in the tests of psychiatric disturbance. The test of psychiatric disturbance sho-wed that the score of general health questionnaire of the female group was significantly higher than that of the male group in the tests of psychiatric disturbance. The illiteracy group was the highest in the psychiatric disturbance among other groups and the unskilled group was significantly higher than the other groups. 4. Education had higher correlation to mini-men-tat state, while age negative correlation in comparison with other variables age had higher correlation to reaction time, while education had negative correlation in comparison with other variables. Sex had low correlation in these tests.

The purpose of this study is to provide the basic information related to electronic picture books and implications for the development of high-quality in-home child care service programs by examining the perceptions and actual conditions of electronic picture books. A survey was conducted with 216 in-home childcare workers from the one Healthy Family Support Center who participated in the workshop on electronic picture books and 161 students from the Department of Early Childhood Education at two Universities as a comparison group. The findings are as follows. First, there was no difference between the two groups in recognition of ICT competencies and satisfaction with electronic picture books. Second, both groups viewed electronic picture books are effective in preparing for the information age and very positive in providing electronic picture books. Third, the valuation of electronic picture books in both groups was higher than that of paper picture books. Fourth, there was no significant difference between the two groups in valuing e-picture books by ICT competence. The results of this study provide implications for the development of systematic educational programs to enhance the job performance of in-home child providers, which will be expanded in the future, by examining ICT competencies, e-picture book actual utilization, and recognition between the in-home childcare providers and ECE students.

This study aims to identify factors affecting the young and middle-aged people's stigma against older adults. By identifying the factors, solutions to lower stigma against older adults can be found. For this study, data from '2017 Age Integration Survey' sponsored by National Research Foundation of Korea and collected on March 2017 were used. Subjects of this study are 854 survey participants residing in 15 districts of South Korea. They are 480 young people aged from 18 to 44 and 374 middle-aged people aged from 45 to 64. T-test, Chow test and Multiple Regression Analysis by SPSS were conducted for the data. These are the results. Both the young and middle-aged people have a similarly high level of stigma against older adults. However, there are significant differences in the variables affecting the level of stigma against older adults between the two age groups. Two common variables affecting stigma against older adults in young and middle-aged people are the recognition of how older adults are depicted in media and age flexibility. The better they recognize discrimination against older adults in media and what an age flexible society is like, the stronger stigma against older adults they tend to have. On the other hand, sex, average monthly income and the opinion on how people treat older adults in their community are significant variables only for the young people. And living district is a significant variable only for the middle-aged people. The significance of this study is that it conceptualized 'stigma' as a cause for discrimination against older adults and focused on the stigmatizing subject, who are the young and middle-aged people, not the stigmatized subject, who are older adults in order to find solutions for lowering stigma against older adults.

This study examines the effect of sociocultural attitude toward appearance and appearance comparison on appearance management behavior by adolescents. The study examines the differences of the effect relationships among the three variables according to adolescents' sex and school grade. The questionnaire was administrated to 575 middle school and high school students in Gwangju from September 2-8, 2011. Data were analyzed by descriptive statistical analysis, frequency analysis, factor analysis, reliability analysis, and regression analysis by SPSS for WIN program. The results were as follows. First, the sociocultural attitude toward appearance was composed of two factors: internalization and awareness. Adolescent's appearance management behavior was composed of four factors: hair and style, face, weight, and neatness. There are significant differences on sociocultural attitude toward appearance and appearance management behavior by gender, age (girl/middle, boy/middle, girl/high, boy/high). Second, the sociocultural attitude toward appearance significantly influenced appearance management behavior with significant differences among groups. Third, the sociocultural attitude toward appearance significantly influenced the appearance comparison and there are significant differences among groups. Fourth, appearance comparison significantly influenced appearance management behavior with significant differences among groups. Fifth, the sociocultural attitude toward appearance mediated by appearance comparison statistically did not influence appearance management behavior.

In this study, the researchers evaluate the hypothesis that the reaction time (RT) in the brain is largely dependent on age and gender. The researchers tested English and Korean words using two types: reading as visual stimuli, and listening as auditory stimuli. The E-Prime program installed in functional magnetic resonance imaging (f-MRI) was used. There are 136 Korean subjects in three groups: 30 children (5th and 6th grade elementary school students), 76 young adults (college students), and 30 adults (35-53 years old). In the listening test, the variation for the two languages was different among the three age groups, regardless of gender, whereas the data did not show meaningful differences in the reading test. The findings will provide some meaningful information regarding perception and acquisition of a foreign language.

Purpose: We aimed to analyze the reliability of the test for choice stepping reaction time (CSRT) under an unstable surface and determine whether there were differences in CSRT between support surface conditions (stable vs. unstable conditions) and between age groups (young adults vs. community-dwelling older adults). Methods: Twenty healthy community-dwelling older adults and twenty young adults performed the stepping task under an unstable condition over two visits. The mean of the two trials measured for each visit was used for the analysis. The test-retest reliability was analyzed using intra-class correlation coefficient (ICC) with a 95% confidence interval, standard error of measurement (SEM), and minimal detectable change (MDC). Differences in CSRT between support surface conditions and age groups were analyzed using the independent t-test with Bonferroni correction. Results: Excellent consistency was observed for ICC >0.90 in both groups. Moreover, the SEM and MDC values of the CSRT in older and young adults were 0.03 and 0.09 and 0.01 and 0.04, respectively. There was a significant difference in the CSRT between the age groups under stable (p<0.001) and unstable conditions (p<0.001). Conclusion: The findings demonstrated that the test for CSRT under an unstable condition had reliable results in both groups. Although older adults demonstrated longer reaction times than younger adults in all surface conditions, increasing the balance control demand by implementing a choice stepping task concomitant with a balance task had no influence on the reaction time in both age groups.
