Purpose: The purpose of this study was to investigate the view on old age of nurses working at general hospitals, geriatric hospitals, oriental hospitals and public health centers. Methods: Data were collected using a self-report questionnaire from 461 nurses working at 3 general hospitals, 8 geriatric hospitals, 7 oriental hospitals and 6 public health centers located in Seoul, Gyeonggi-do and Chungcheong-do from June 20 to September 6, 2012. Results: The mean score of the nurses' view about old age was 3.38 out of 5 points. The details show that the 'society character' was the highest at 4.58, followed by the 'capacity character' 3.94, the 'psychology-economical character' 3.02 and the 'physical-cognitive character' 2.71. As for workplace, oriental hospitals had the highest points on the view about old age, while geriatric hospitals had the lowest. Conclusion: The results of this study indicated that the nurses' view about old age were above the moderate level. As for workplace, geriatric hospital nurses had the lowest view about old age. Therefore, it is recommended to develop an educational program that may promote the nurses' view about old age and provide the better elderly care service.

This study investigates the effects of clothing consumption values and subjective age on fashion adoption. To explain the fashion adoption of elderly women, 5 dimensional consumption values were adopted as explanatory factors, and subjective age is included as a moderating factor. This study tested the relationship of variables with survey data from a convenient sample of elderly women. A total of 235 complete responses were obtained from women between 50 and 71 years of age. The results are as follows. First, factor analysis on clothing consumption values resulted in 5 dimensional structures of consumption values for the sample (epistemic, symbolic, harmonic, popular, and practical values). A factor analysis on subjective age resulted in 2 dimensions (physical and mental age). Second, epistemic, popular, harmonic (-) and symbolic values (except practical value) significantly affected fashion adoption. Third, the epistemic value was the strongest factor regardless of physical and mental age but the effects of epistemic, popular, harmonic, symbolic, and practical values changed depending on the level of the moderating factor.

Purpose: This study aimed to identify the factors related to fear of falling (FOF) in different age groups from community-dwelling mid to late-adults. Methods: To identify the factors related to FOF, data of 162,684 adults over 45 years of age from 2019 Community Health Survey was analyzed using logistic regression with complex samples. Results: Factors related to FOF found in all age groups were sex, previous experience of falls, physical activity levels over moderate intensity, subjective health status, number of chronic diseases, stress, depression, and cognitive decline. In the 45-64 age group, the FOF was significantly higher in the groups of low education level and low monthly household income. In the 65-74 and over 75 age groups, the FOF was significantly higher in the groups of not living with spouse and walking not practiced. Conclusion: We suggests that understanding of risk factors and early detection of fall risk patients in each age group are necessary to establish and apply tailored fall prevention programs for prevention and management of the FOF in community-dwelling mid to late-adults.

Thymic epithelial cells (TECs) play a critical role in thymic development and thymopoiesis. As individuals age, TECs undergo various changes that impact their functions, leading to a reduction in cell numbers and impaired thymic selection. These age-related alterations have been observed in both mice and humans. However, the precise mechanisms underlying age-related TEC dysfunction remain unclear. Furthermore, there is a lack of a comprehensive study that connects mouse and human biological processes in this area. To address this gap, we conducted an extensive transcriptome analysis of young and old TECs in mice, complemented by further analysis of publicly available human TEC single-cell RNA sequencing data. Our analysis revealed alterations in both known and unknown pathways that potentially contribute to age-related TEC dysfunction. Specifically, we observed downregulation of pathways related to cell proliferation, T cell development, metabolism, and cytokine signaling in old age TECs. Conversely, TGF-β, BMP, and Wnt signaling pathways were upregulated, which have been known to be associated with age-related TEC dysfunctions or newly discovered in this study. Importantly, we found that these age-related changes in mouse TECs were consistently present in human TECs as well. This cross-species validation further strengthens the significance of our findings. In conclusion, our comprehensive analysis provides valuable insight into the biological and immunological characteristics of aged TECs in both mice and humans. These findings contribute to a better understanding of thymic involution and age-induced immune dysfunction.

The purpose of the study was to investigate the self-esteem, appearance satisfaction, and clothing benefit pursuit the gap between subjective age and real age according to gender and age of middle-aged consumers. For the study, the questionnaire was developed by the authors and distributed to male and female consumers in their forties or fifties on september 1~10, 2014. A total of 470 questionnaires was collected and used for the final analysis. Data were analyzed by frequency analysis, reliability analysis, factor analysis, cluster analysis, ANOVA and Tukey's test, using the SPSS 18.0 Package Program. The findings were summarized as follows. There were significant differences in the subjective age of middle-aged consumers according to gender and age. Female consumers in their fifties perceived their subjective age to be younger than male consumers in forties and fifties. There were no significant differences in self-esteem among the groups according to gender and age. Significant differences were found in appearance satisfaction of male consumers in their fifties having higher appearance satisfaction than female consumers in their forties. There were significant differences in some factors of clothing pursuit benefits including pursuit of fashion, pursuit of youth, pursuit of rationale, pursuit of leisure, and pursuit of loyalty, among the groups according to gender and age with female consumers placing more importance on clothing-related benefits than their male counterparts. Local fashion businesses to consumers who target middle-aged consumers, this study can provide a basic data.

The present study was undertaken to evaluate the accuracy of ultrasonography in early pregnancy diagnosis in goats. Ultrasonographic scanning with real time B-mode ultrasound machine having 5 MHz linear array transducer was performed on gravid uterus (n=24) obtained from slaughterhouse (Group I). Crown rump length (CRL) measured by ultrasound was found significantly different (p<0.05) with actual CRL measured after dissection in early pregnancy. However, age predicted by ultrasound through the measurement of CRL was found highly correlated (r=0.92) with age measured after dissection through CRL and the weight of fetus. Ages predicted by ultrasound through the measurement of trunk diameter (TD) and uterine diameter (UD) and ages measured after dissection were found highly and equally correlated (r=0.98) and did not differ significantly. Data from six does synchronized (Group II) with PGF2$\alpha$ (Estrumate) at 11 days apart were collected through ultrasound from 17 to 42 days post breding. The correlation between CRL and gestational age was high (r=0.97) in day 30 to 42 post breeding. A high coefficient of correlation (r=0.98) was also observed between predicated age by ultrasound and actual age calculated after kidding. The correlation between CRL and gestational age by the formula Y=(a+bX) i.e. Y=24.42+0.39 X where Y=gestational age and X=CRL, was recorded very high (r=0.99). Accuracy of ultrasonography was lowest on day 17 to 19 (66%) and reached 100% on day 34. Data from 30 does (group III) randomly subjected to only one time ultrasounds scanning to assess the accuracy of pregnancy diagnosis were also obtained. Ages predicted by TD and UD measurements were observed to be non-significantly different with actual age obtained after kidding and correlation between ages predicted by TD and UD measurement with actual age after kidding was found equally and highly correlated (r=0.98). The operator's accuracy in the whole experiment including all three groups was found to be 92%. The sensitivity was 93% and specificity was 86%. From the present study, it was observed that CRL was the most reliable parameter to find out gestational age in early pregnancy and the new formula derived was found very accurate to find out gestational age. TD and UD were also found to be equally reliable parameter to find out gestational age in mid and late stage of pregnancy through ultrasonography. It was concluded that ultrasonography by real time B mode with 5 MHz transrectal transducer was found to be reliable, safe and accurate and practicable means in diagnosing early pregnancy diagnosis as early as 25 days post breeding.

PURPOSE This study was intended to analyze the play-form of normal preschool children as related to age, sex, educational experience and social maturity. METHOD 1. Subjects The subjects of this study were eighty seven 3-, 4- and 5-year-old preschool children attending educational institutions in Seoul. 2. Instruments The instruments used in this study consisted of twenty one-minute observations in 5 preschool settings and a questionnaire designed to measure the children's social maturity filled in by their parents. The observations provided information on the children's free play, that is 1) play-form: solitary, parallel and group play 2) use/non-use of toys 3) behavior: play, activity, doing nothing, onlooking 4) stationary/moving dimensions 5) play group size The questionnaire measured such factors as communication, socialization, locomotion, self-help and self-direction. 3. Data Analysis Data analysis consisted of percentage and Chi square. RESULTS 1. Play-Form The relationship between age and play-form proved to be significant at the .05 level. That is, in both boys and girls, solitary play decreased with age and group play increased with age while parallel play maintained a similar position. The relationship between sex and play-form proved to be significant at the .05 level in 3-& 4-year-old children, but not significant in 5-year-old children. That is, in their $3^{rd}$ year boys engage in the solitary play more than girls and in their $4^{th}$ year boys engage in more group play than girls. 2. Toys Without differentiation of sex and age, cases of using toys in play exceed those cases where toys were not used. 3. Behavior The relationship between age and behavior proved to be significant at the .05 level in both boys and girls. That is, with increase of age, play decreased and activity increased in boys while play increased and doing nothing decreased in girls. 4. Moving Status Totally, moving occurred more frequently in play than stationary status. Moving proved not to have a significant relationship with age, but it did Navel a significant relationship with sex at the .05 level. That is, moving tended to increase with the increase in age in both boys and girls, but not at a significant level. Boys moved significantly more than girls in all three age levels. 5. The Relationship between Educational Experience and Play-Form There was a tendency for children with longer preschool experience to engage in less solitary play and more group play than children who had less than one semester of preschool experience, but this difference was not statistically significant. 6. The Relationship between Social Maturity and Play-Form The high social maturity group engaged in less solitary play and more group play than the low social maturity group, but this was not a statistically significant difference. 7. Play Group Size Play group size was 2~10 children, but the majority of play groups consisted of 2~3 children. There was a tendency for play groups composed of 2 children to decrease with age and play groups composed of 3 children to increase with age. No significant difference was found between the sexes in play group size.

Background: The purpose of this study was to evaluate the long-term survival rates of very elderly (age ≥80) critically ill patients admitted to a medical intensive care unit (MICU) at a regional tertiary-care hospital in Korea. Methods: We retrospectively analyzed data from patients who survived after discharged from the MICU of our hospital. Survival rates at 90 days, 1 year, 2 years, and 3 years were assessed between patients age ≥80 and those age <80. Survival status was evaluated using the National Health Insurance Service data. Results: A total of 468 patients were admitted, 286 (179 males, 97 females; mean age, 70.18±13.2) of whom survived and were discharged soon after their treatment. Among these patients, 69 (24.1%) were age ≥80 and 217 (75.9%) were age <80. The 90-day, 1-year, 2-year, and 3-year survival rates of patients age ≥80 were significantly lower than those in patients age <80 (50.7%, 31.9%, 15.9% and 14.5% vs. 68.3%, 54.4%, 45.6%, and 40.1%, respectively) (p<0.01). The Kaplan-Meier survival curves showed significantly lower survival rates in patients age ≥80 than in those age <80 (p=0.001). Conclusion: The poor rates of long-term survival in very elderly (age ≥80) and critically ill patients admitted to an ICU should be considered while managing and treating them.

Objectives: To compare the performance of three International Statistical Classification of Diseases, 10th Revision translations of the Charlson comorbidities when predicting in-hospital among patients with myocardial infarction (MI). Methods: MI patients ${\geq}20$ years of age with the first admission during 2006 were identified(n=20,280). Charlson comorbidities were drawn from Heath Insurance Claims Data managed by Health Insurance Review and Assessment Service in Korea. Comparisions for various conditions included (a) three algorithms (Halfon, Sundararajan, and Quan algorithms), (b) lookback periods (1-, 3- and 5-years), (c) data range (admission data, admission and ambulatory data), and (d) diagnosis range (primary diagnosis and first secondary diagnoses, all diagnoses). The performance of each procedure was measured with the c-statistic derived from multiple logistic regression adjusted for age, sex, admission type and Charlson comorbidity index. A bootstrapping procedure was done to determine the approximate 95% confidence interval. Results: Among the 20,280 patients, the mean age was 63.3 years, 67.8% were men and 7.1% died while hospitalized. The Quan and Sundararajan algorithms produced higher prevalences than the Halfon algorithm. The c-statistic of the Quan algorithm was slightly higher, but not significantly different, than that of other two algorithms under all conditions. There was no evidence that on longer lookback periods, additional data, and diagnoses improved the predictive ability. Conclusions: In health services study of MI patients using Health Insurance Claims Data, the present results suggest that the Quan Algorithm using a 1-year lookback involving primary diagnosis and the first secondary diagnosis is adequate in predicting in-hospital mortality.
