This study investigated the causality of the children's self-perceived competence and related variables(age, sex, socio-demographic variables, family structure, the number of brother, home environmental process variables and peer group environmental variables.) The subjects of this study were 842 children at age five, seven, nine, eleven and thirteen attending kindergartens. elementary schools and junior high schools and their mothers in Seoul. This study employed children's self-perceived competence scales(The Pictorial scales for 5, 7, Qestionnaire for 9, 11, 13) home environment scales and peer group enviornment scales(the Pictorial scales for 5, 7 Qestionnaire for 9, 11, 13) Freqencies one way-ANOVA Pearson's Cronbach's αmultiple regression and path analysis were used for data-analysis. Major findings were as follows: 1. The results of the analysis of causal model showed that the variables that affected cognitive self-perceived competence directly were age, sex, parent's education economic status of the home the number of brother and peer's emotional support 2. The results of the analysis of causal model showed that the variables that affected social self-perceived competence directly were sex, economic status of the home, peer's emotional support and common activity. 3. The results of the analysis of causal model showed that the variables that affected physical self-perceived competence directly were age, sex, peer's emotional support and common activity.

Objectives : Period analysis estimates up-to-date survival rates of cancer patients. In this approach, analysis is restricted to recent time period by left-truncating all observations at the beginning of the period and right-censoring at its end. Here, we applied period analysis to examine changes in 5-year relative survival (RS) by age group for 1997 and for 2002. Methods : Using the National Cancer Incidence Database, 5-year RS was estimated for 1997 and 2002 in four age groups (15-54, 55-64, 65-74, and 75 years old and over) using period analysis. After excluding death certificate-only cases, patients with an unknown date of diagnosis or follow-up length, a total of 813,889 patients diagnosed with a first primary invasive cancer during 1992 2002 were included for analysis. Followup for vital status was included until 31 December 2002. Results : Five-year RS increased from 41.7% for 1997 to 46.7% for 2002. Increases in survival occurred in all age groups except in the 75 and over group. Conclusions : The age gradient in cancer prognosis seems to have widened between 1997 and 2002, a finding that requires further study of prognostic factors, including stage at diagnosis. Period analysis accurately estimates survival rates, especially for cancers with better prognosis.

This study explores the effects of business consulting on the business performance of firms by using a unique survey for various industry sectors in Korea. We attempt to build a consulting model that shows the structural relationship between consulting factors and consulting performance. Moreover, through the consulting model, we conduct the analysis of elasticity of consulting factors and the group analysis based on firm age. First, the findings show that all consulting factor has a positive impact on the consulting performance, but in the results of factor elasticity, they have a somewhat different impact. Second, while the support of CEOs is relatively more elastic than other consulting factors with respect to the completion of consulting projects, the institutional condition for consulting is relatively more elastic than other factors with respect to the contribution to business performance. Third, since the high-firm age group has a greater capacity to absorb and utilize external knowledge and resource, the consultant competency and institutional conditions have a more impact on the consulting performance than the low-firm age group. On the other hand, in the low-firm age group, the result indicates that the support of CEOs has a more impact in the consulting performance than the high-firm age group. According to the total effect, the support of CEOs in the entire model has the highest impact on the consulting performance. Thus, it is probably difficult to achieve the improvement of business performance through consulting as well as the successful consulting projects without the CEOs' commitment and awareness about the consulting projects.

Objectives The purpose of this study is to analyze the characteristic of the 157 pediatric patients who visited a Korean medical hospital for bone age (BA) measurement and to compare the BA measurement using Tanner-Whitehouse 3-based analysis software and specialists in pediatric Korean medicine to determine the relationships. Methods The study included 157 pediatric patients who visited a Korean medicine hospital for BA measurements from June 2021 to June 2023. They were analyzed to determine the characteristics and agreement of BA measurements using Tanner-Whitehouse 3-based analysis software and specialists using classification by age, intraclass correlation coefficient (ICC), and Bland-Altman plots. Results In total, 61.8% of the study population were boys and 38.2%, girls, with an average age of 11.32 ± 1.87. The types of growth were various, and the average of bone maturity was 0.48 ± 1.13 as concluded by analysis software and 0.38 ± 1.15 as concluded by the specialists. The ICC of two methods were excellent: 0.995 (overall), 0.996 (boys) and 0.994 (girls). However, BA determined by analysis software tended to be higher than that determined by specialists when the patients were young. Conclusions This study showed that patients visited the hospital for BA measurement regardless of their height, and the agreement of BA between the two methods can be used as a reference. However, there was differences in the trends between age and sex, which should be interpreted with caution.

The aim of this paper is to examine the effectiveness of combining three popular tools used in pattern recognition, which are the Active Appearance Model (AAM), the two-dimensional discrete cosine transform (2D-DCT), and Kernel Fisher Analysis (KFA), for face recognition across age variations. For this purpose, we first used AAM to generate an AAM-based face representation; then, we applied 2D-DCT to get the descriptor of the image; and finally, we used a multiclass KFA for dimension reduction. Classification was made through a K-nearest neighbor classifier, based on Euclidean distance. Our experimental results on face images, which were obtained from the publicly available FG-NET face database, showed that the proposed descriptor worked satisfactorily for both face identification and verification across age progression.

This study tried to find various alternatives to live the rest of life positively by examining whether satisfaction with work in old age has a positive effect on psychological adjustment in old age. Using the 15th (2020) data of the Korea Welfare Panel Study (KOWEPS), 117 men and 355 women were analyzed as a sample to verify the effect of job participation satisfaction among the elderly on psychological adjustment. The results of the regression analysis in this paper (F=11.680, p<.001) were analyzed to be significant. The results showed gender (β=-.192, p<.001), age (β=2.004, p<.001), and job participation satisfaction (β=-3.726, p<.001). Therefore, it was found to have an effect on psychological adaptation. In terms of gender, it was found that men had higher psychological adaptability than women, and that the lower the age, the higher the psychological adaptability. As a result, it was confirmed that the elderly's job participation is a simple economic part of the elderly, and the psychologically positive influence increased. The higher the job participation satisfaction, the higher the psychological adaptability.

The subject of this study is a cohort of elderly women who are older than 60 years of age and reside S city in and Jeonnam. The sample size of this study is 386. The statistics used for data analysis were frequency, percentage, mean, standard deviation, reliability, ANOVA, correlation, and multiple regression analysis through the SAS package program. The major study result were as follows. First, the physical satisfaction of elderly women is low, and the life satisfaction of the married group is higher than for the widowed group. Second, according to the results. For the women from the married group, the effect were from economic state, age, and physical satisfaction. There were also significant interaction effects according to economic state$\times$physical satisfaction, age$\times$economic state$\times$physical satisfaction, and age$\times$physical satisfaction. As for women from the widowed group, the effect were from physical satisfaction, economic state, and age. There were also significant interaction effects according to economic state$\times$physical satisfaction, age$\times$physical satisfaction, age$\times$economic state$\times$physical satisfaction, and age$\times$economic state. Fourth, the married group gave significance to life satisfaction, economic state, physical satisfaction, and age. The group of widows gave significance to life satisfaction, physical satisfaction, economic state, and age. The results of this study suggest that we should be concerned about the physical satisfaction of older women and should foster a social atmosphere to establish a positive image of elderly women.

The advanced glycation endproducts receptor (AGE-R) is a signal transduction receptor for multiligand such as S100b and AGEs. S100b has been demonstrated to activate various cells with important links to atherosclerosis initiation and progression including endothelial cells, and smooth muscle cells via AGE-R, triggering activation of multiple signaling cascades through its cytoplasmic domain. Many studies have suggested AGE-R might even participate in the cardiovascular complications involved in the pathogenesis of type I diabetes. Recently, Small Ubiquitin-Related Modifier 1 (SURM-1 also known as SUMO-1) has been recognized as a protein that plays an important role in cellular post-translational modifications in a variety of cellular processes, such as transport, transcriptional, apoptosis and stability. Computer Database search with SUMOplot Analysis program identified the five potential SURMylation sites in human AGE-R: K43, K44, K123, and K273 reside within the extracellular domain of AGE-R, and lastly K374 resides with the cytosolic domain of AGE-R. The presence of the consensus yKXE motif in the AGE-R strongly suggests that AGE-R may be regulated by SURMylation process. To test this, we decided to determine if AGE-R is SURMylated in living vascular cell system. S100b-stimulated murine aortic vascular smooth muscle cells were used for western blot analysis with relevant antibodies. Taken together, bioinformatics database search and molecular biological approaches suggested AGE-R is SURMylated in living cardiovascular cell system. Whilst SURMylation and AGE-R undoubtedly plays an important role in the cardiovascular biology, it remains unclear as to the exact nature of this contribution under both physiological and pathological conditions.
