Purpose To compare the computerized Greulich-Pyle based bone age with elbow bone age. Materials and Methods A total of 2126 patients (1525 girls; 601 boys) whose elbow bone age was within the evaluable range by the Sauvegrain method, and who simultaneously underwent hand radiography, were enrolled in the study. The 1st-bone age and VUNO score of the hand were evaluated using VUNOMed-BoneAge software. The correlation between the hand and elbow bone age was analyzed according to the child's gender and the probability of 1st-bone age. Results The correlation between VUNO score and elbow bone age (r = 0.898) was higher than the correlation between 1st-bone age and elbow bone age (r = 0.879). Moreover, the VUNO score showed a better correlation with the elbow bone age in patients with a 1st-bone age probability of less than 70%, or in girls. Elbow bone age was more advanced compared to hand bone age, and this difference increased until the middle of puberty and gradually decreased in the latter half. Conclusion The computerized Greulich-Pyle based hand bone age showed a significant correlation with the elbow bone age at puberty. However, since the elbow bone age tends to advance faster than the hand bone age, caution is required while judging the bone age during puberty.

This study conducted a survey to analyze the influence of the consumer-brand interaction and the consumer-brand relationship on motivation and satisfaction based on the perceived age of men and women in their teens and 50s who subscribe to cosmetic brands through SNS accounts. For statistical processing of the collected data, frequency analysis, factor analysis, reliability analysis, regression analysis, and multiple regression analysis were performed with SPSS 21.0. The perceived age of the subjects was classified into 'perceived lower group', 'perceived middle group', and 'perceived higher group' according to the difference between the age perceived by others and the age perceived by themselves. In the three groups, the consumer-brand interaction and the consumer-brand relationship showed a meaningful positive relationship with motivation, and the consumer-brand relationship was found to be a major variable explaining 'attractive' among motivation. In the three groups, the consumer-brand interaction and the consumer-brand relationship showed a significant positive relationship with satisfaction, and the consumer-brand relationship appeared as a major variable explaining satisfaction. Therefore, the conclusion of this study is that by perceived age group, the consumer-brand interaction and the consumer-brand relationship have a positive effect on motivation and satisfaction. In particular, it was found that the consumer-brand relationship is a major variable in cosmetics motivation and satisfaction. As this study empirically analyzes the influence of age perceived on SNS on cosmetics brand marketing, it is considered to be a practical implication for establishing cosmetics sales strategy and basic data that can be used for marketing.

Using structural equation modeling, this study sought to examine the structural causality between elderly age norms, social activities, and life satisfaction and to determine the moderating effect of death preparation activities. The analysis was conducted using data for 6,288 people over 65 years old, plus their spouses and children, taken from the '2017 National Survey of Older Koreans.' The study found, first, that the more positive the age norms to which the older person subscribes, the more their social activities increase. Second, as these social activities increase, the level of life satisfaction also increases. Third, the more positive the age norms to which the older person subscribes, the more the level of life satisfaction increases. Fourth, there is a significant positive mediating effect of social activity in the relationship between the age norms of the older person and life satisfaction. Fifth, there is a significant moderating effect of death preparation activities in the structural relationship between age norms, social activities, and life satisfaction that specifically impacts the age norm-life satisfaction relationship. Based on these results, practical plans to improve elderly people's life satisfaction are recommended.

Although previous studies have found that social participation activities are related to older people's life satisfaction and health status, the rate of social participation activities among older people is still low. The current study examined the relationship between age identity and social participation activities among older people and the extent to which this relationship differs by gender. Secondary data from the Survey of Living Conditions of Korean Older Persons were used to test the research hypothesis. Hierarchical multiple regression models were tested using a nationally representative sample of 10,451 community-dwelling older persons aged 65 and above. Older people who have older age identity were less likely to involve in social participation activities than those who have younger age identity. However, this relationship was only significant for older women. The findings suggest the need for attention to age identity and gender differences when promoting social participation activities.

Declining research competitiveness and inefficiency are constantly being raised in the National Assembly and the media for the Government-funded Research Institutes(GFRIs), which are highly dependent on government funding. These external stakeholders point to the workforce aging of the GFRIs as one of the main causes of inefficiency. They insist that the aging leads to an increase in labor costs, a discontinuity in research, a decrease in employment of new researchers, and a decrease in research competitiveness. However, the GFRIs argue that the aging is a natural phenomenon due to an increase in the age of recruitment, and even if there is an side effect, it is extremely small or even vice versa. It is interesting that there is no empirical study identifying the correlation between the workforce aging and the research performance of the GFRIs, despite the discussion. This study tracked and analyzed the changes of the research performance and the workforce for the five years from 2011 to 2015, and tried to demonstrate the correlation between the workforce aging and the research performance. As a result, we confirmed that there is an inverted U-type correlation between the aging and the papers, one of the research performance, and that the optimal age is 44.96 years. Also, we could not find any correlation between the aging and the patents.

This study empirically analyzed the factors that intensify the unequal distribution of relational goods through the decomposition of relational gaps and the actual condition of relational goods. The results of the analysis are as follows. First, the average time for forming a relationship with family members or others is 158 minutes in 24 hours a day. Second, tobit regression analysis showed that relational goods time increased as they were employed, more family members, and ownership of their home. On the other hand, relational goods decreased when they were female, double-working, aged, divorced, and increased working time. The increase in household income decreased family relational goods, but increased the time with others. Based on the results of this analysis, this study proposed reduction of working time as a way to increase the happiness by sharing the relationship with meaningful people.

This study examines the contrasting effects of an aging workforce on organizational innovation and the moderating role of age diversity. By utilizing a knowledge-based view, this study asserts that an aging workforce can contribute to organizational innovation to some degree due to accumulated firm-specific knowledge and experiences as well as various social networks within and outside the firm. On the contrary, as the portion of an aging workforce increases, the negative effect of the aging workforce on organizational innovation can overwhelm the positive effects because of the limitations of new knowledge creation. In addition, this study explores the effect of age diversity to moderate the relationship between aging workforce and organizational innovation.Empirical findings showed that an aging workforce and organizational innovation had an inverted-U relationship, and age diversity moderated this curvilinear relationship as this study predicted. These theoretical arguments and empirical findings highlight the necessity to explore the complex effects of an aging workforce on organizational innovation as well as additional factors influencing the relationship between aging workforce and firm innovation.

The study investigated the relationship between subjective socioeconomic status (SES) of 508 Korean adults and their perception of justice (distributive and procedural justice for self and general others), and verified whether there is a moderating effect of age (20s versus 30s and over). A self-report survey on SES and perception of justice was conducted. Then, using the SPSS 27 and PROCESS Macro 4.0 program, a correlation analysis looking into the relationship among the study variables was performed along with the ANOVAs comparing the mean differences of study across age-groups to support the group division criteria. Next, a moderation analysis was conducted. The main results of this study are as follows. First, the participants' SES showed a positive relationship with all sub-factors of justice perception and a negative relationship with age. Second, age had a inverse relationship on distributive justice for self and general others, and procedural justice for self, but a non significant relationship on procedural justice for general others. Third, when looking into the mean differences of the research variables according to age, the 20s had different characteristics compared to the 30s and over. In comparison, there were no significant differences within the 30s and over group. Fourth, the moderating effect of age in the relationship between subjective SES and perception of justice was positively significant in the case of distributive justice for self and procedural justice for general others. In the case of distributive justice for self, the positive slope of the graph in which subjective SES predicts distributive fairness for self was steeper in the 30s and older group compared to the 20s. Regarding the procedural justice for general others, subjective SES was not a significant predictor in the 20s group. However, SES positively predicted procedural justice in the 30s and older group. This study is meaningful since it suggested age differences in subjective SES and perceptions of justice by revealing the different relationship patterns of subjective SES and perception of justice according to age.
