This study investigates influence of parental attachment on school adjustment using self-perceived competence as a mediating variable for perceived school age children. The subjects were 760 children who are 4, 5, and 6 grades in 4 elementary schools at Daegu. The collected data were analyzed by single and multiple regressions that used SPSS win 19.0 The results were as follows: (1) The parental Attachment perceived by school-age children was positively associated with on school adjustment. The parental attachment level of school-age children becomes higher as the perception of school adjustment increases. (2) The parental attachment perceived by school-age children was positively associated with self-perceived competence. That is, the parental attachment level of school-age children becomes higher as the self-perceived competence increase. (3) The effect of parental attachment in the school adjustment by children was reducing explanation when controlled for the self-perceived competence. The Parental attachment that influenced the school adjustment is partially mediated by self-perceived competence. The results of this research indicates that both the quality improvement of inter-relationship between children and parents for school adjustment of school-age children and training for strengthening self-perceived competence of school-age children are important.

Perceived age is defined as age estimated based on physical appearance. Perceived age is an important indicator of the overall health status of the elderly. This is because people who appear older tend to have higher rates of morbidity and mortality than people of the same chronological age. Although perceived age is an important indicator, there is a lack of objective methods to quantify perceived age. In this paper, we construct a quantified perceived age model from face images using a convolutional neural network. The face images are enlarged to super-resolution and the skin, an important feature in perceived age, is made clear. Moreover, through Tanh-polar transformation, the central area of the face occupies a relatively larger area than the boundary area, helping the neural network better recognize facial skin features. The experimental results show mean absolute error (MAE) of 6.59, showing that the proposed model is superior to existing method.

Objective: This study aimed to examine the sequential mediating effects of children's perceived maternal acceptance and peer acceptance in the relationship between maternal warmth and first grade children's school adjustment. Methods: Participants in this study were 979 seven-year-old children(498 boys, 481 girls) recruited for the Korea Child Panel Study. Data were analyzed by analyzing descriptive statistics, correlations, and significance of serial mediation pathways using SPSS 18.0 and PROCESS Macro 3.4. Results: Maternal warmth at age five effected perception of maternal acceptance at age six. Perceived maternal acceptance at age six effected perceived peer acceptance at age six. Perceived peer acceptance at age six effected school adjustment at age seven. Lastly, perceived maternal acceptance and peer acceptance at age six had a serial mediation effect between maternal warmth at age five and school adjustment at age seven. Conclusion/Implications: Perceived social acceptance during preschool years should be emphasized in order to promote school adjustment for first grade children. Parent education for promoting better parent child relationships should be considered and teachers should encourage peer play interaction to help children perceive acceptance from their peers.

Purpose: Perceived barriers to exercise were investigated for adults. Method: A total 1266 subjects were selected by a quota sampling method with age, gender, and residence. Perceived barriers were categorized under 4 groups: knowledge, psychological, physical, and external factors. All 23 items of perceived barriers were responded on a dichotomous (yes/no) scale. Result: Mean number of perceived barriers was 4.61 and 87.9% subjects perceived at least one barrier which prevented involvement in exercise. External barriers ranked highest, followed in order by psychological, knowledge, and physical barriers. Most factors of perceived barriers were found to be different by age, gender, and residence, in that, the younger, female, living in Daejeon subjects were found to respond with more barriers than the older, male, living in Chungju or Seoul. Conclusion: Perceived barriers to exercise are differenct by age, gender, and residence. Therefore, it is recommended that age, gender, and residence of subjects must be considered in order to develop exercise programs and public campaigns.

The normal aging process on speech production and these changes are perceived by listeners. This study examined whether age perception changed under various conditions of prosodic manipulations in normal listeners, comparing the prosodic changes according to age and sex in adulthood. The older and younger voices were resynthesized by manipulation of the speaking rate and pitch to shift the perceived age of the groups toward each other. Two-way repeated ANOVA were conducted to determine if the prosodic type of resynthesized cue resulted in a significant shift in perceived age of young and old voices. The manipulation of the speaking rate resulted in a significant shift in perceived age for the older and younger groups. A significant shift in age estimates was not observed for the younger male group when pitch was manipulated. There were significant gender-by-age group interactions for prosodic manipulation type. Age-related changes in the prosodic properties of speech may ultimately influence speech perception.

The purpose of this research is to understand the general consumer knowledge and adoption intention of nanotechnology products, one of the advanced scientific fields. We examined consumers' knowledge of innovation products based on nanotechnology, by gender and age group, which are divided into benefits, cost, and trust perception. As a result, the benefits were highly perceived in the order of perceived usefulness, perceived gains, and perceived ease of use. In general, it was found that men and older age group perceived the benefits of nanotechnology to be relatively higher than women and younger age groups did. In terms of cost, perceived risk was relatively higher than other variables and a high innovation resistance appeared in the younger 30s group. Finally, we found that trust for nano-related institution is relatively lower than trust for nano-related people and trust for nanotechnology itself.
