As the global elderly population rapidly increases, the mental health of the elderly, particularly depression, has emerged as a significant social issue. This study analyzes the various factors influencing depression in the elderly based on the ICF model. Utilizing data from the Korea Welfare Panel Study, the study identifies the types of changes in depression among individuals aged 65 and older and examines the factors influencing these changes. This longitudinal secondary data analysis research uses the most recent three years of data (2021-2023) from the Korea Welfare Panel. The study sample consisted of 965 elderly individuals, and a latent class growth model was applied to identify the types of depression changes, while a multinomial logistic regression analysis was conducted to analyze the influencing factors. The analysis revealed that elderly depression could be categorized into four types: high-level decrease, high-level maintenance, low-level increase, and low-level maintenance. Main influencing factors included gender, age, education, poverty, social trust, social relationships, participation in economic activities, participation in religious activities, and health status. Particularly, social relationships and health status were significant factors affecting the types of depression changes. To mitigate depression in the elderly, a multifaceted approach considering both individual characteristics and social relationships and health status is required. The study suggests the development of community-based programs and trust-building activities at the community level to maintain and strengthen the social relationships of the elderly. These findings can serve as important foundational data for policies and practices aimed at improving the mental health of the elderly.

Live-streaming commerce business is growing as the consumption of video content and Smartphone shopping increases. This study examines the following three aspects: whether para-social interaction influences perceived interactivity; whether seller trust affects satisfaction with the experience; whether relationships are controlled by a moderated mediator of self-image congruity. An online survey was conducted with 203 women aged 20-30 years. They were asked to respond to the survey after watching a beauty category live-streaming commerce broadcast. The results revealed that the para-social interaction had a significant effect on perceived interactivity, seller trust and satisfaction with the experience. The findings also indicated that the perceived interactivity and seller trust mediated the relationship between para-social interaction and satisfaction with the experience. Regarding the mediated moderation effect of self-image congruity, it was statistically significant between para-social interaction and perceived interactivity through seller trust. A higher level of consumer's self-image congruity influenced the greater effect of para-social interaction on live commerce experience. This study makes important theoretical contributions to the para-social interaction in mobile commerce industry by emphasizing the mediating role of perceived interactivity and seller trust. This is achieved by examining the moderating effects of self-congruity on satisfaction with the experience. The results also verify the seller's crucial role in live-streaming commerce market which leads to the consumers greater fulfillment.

The rural elderly population has social capital based on regionalism and kinship, which acts as a positive function in terms of their self-efficacy. Self-efficacy refers to the belief in one's own abilities. In general, elderly people with high self-efficacy maintain a healthy life and age successfully. This study examines how the rural elderly population perceive their self-efficacy and social capital and analyzes the role of social capital as a mediating variable. Social capital consists of 4 aspects; trust, norms, network and participation. For this study, data were gathered from 344 rural elderly people aged 60 years and over. The results of this study were as follows. According to the analysis of the structure equation modeling effect, the direct effect of subjective health status on self-efficacy, the indirect effect of the parameters of norms and the total effect were all statistically significant. Second, the direct effect of adult children's support on self-efficacy was significant, and the indirect effects of the parameters of trust, norms and total effect were all statistically significant. This study confirmed that social capital has a mediating effect on the relationship among the subjective health status of the rural elderly, adult children's support and self-efficacy. Furthermore, social capital had a positive impact on the self-efficacy of the rural elderly. Based on these results, a policy for making use of the social capital of the rural elderly should be developed.

This study: 1) identifies differences in consumers' perceived similarity of extended products to their parent product in terms of brand attributes, 2) identifies the influence of the perceived similarity on consumer's attitude toward and purchase intention of extended products (i.e., brand extension effect), and 3) examines the moderating effect of Brand Relationship Quality (BRQ) on brand extension effects. A survey questionnaire was distributed to a convenience sample of individuals aged 20-39. A total of 576 valid responses were used for the final analysis. The results showed that: 1) the consumers perceived more similarity in the extended products when the extended products maintain more consistent attributes with their parent product, 2) the higher the perceived similarity was then the higher the brand extension effect, and 3) brand relationship quality moderated the influence of perceived similarity on attitude and purchase intention. When consumers build a high relationship quality with a brand, then the brand extension effect is likely to be high regardless of the perceived similarity of the extended products. This study consequently has its own contribution in that it empirically examined the brand extension effect in the fashion field and evidenced the role of BRQ in brand extension.

Cast iron pipe has been used as a water distribution technology in North America since the early nineteenth century. The first cast iron pipes were made of grey cast iron which was succeeded by ductile iron as a pipe material in the 1940s. These different iron alloys have significantly different microstructures which give rise to distinct mechanical properties. Insight into the non-destructive structural condition assessment of aging pipes can be advantageous in developing mitigation strategies for pipe failures. This paper examines the relationship between the small-strain and large-strain properties of exhumed cast iron water pipes. Nondestructive and destructive testing programs were performed on eight pipes varying in age from 40 to 130 years. The experimental program included microstructure evaluation and ultrasonic, tensile, and flexural testing. New applications of frequency domain analysis techniques including Fourier and wavelet transforms of ultrasonic pulse velocity measurements are presented. A low correlation between wave propagation and large-strain measurements was observed. However, the wave velocities were consistently different between ductile and grey cast iron pipes (14% to 18% difference); the ductile iron pipes showed the smaller variation in wave velocities. Thus, the variation of elastic properties for ductile iron was not enough to define a linear correlation because all the measurements were practically concentrated in single cluster of points. The cross-sectional areas of the specimens tested varied as a result of minor manufacturing defects and levels of corrosion. These variations affect the large strain testing results; but, surface defects have limited effect on wave velocities and may also contribute to the low correlations observed. Lamb waves are typically not considered in the evaluation of ultrasonic pulse velocity. However, Lamb waves were found to contribute significantly to the frequency content of the ultrasonic signals possibly resulting in the poor correlations observed. Therefore, correlations between wave velocities and large strain properties obtained using specimens manufactured in the laboratory must be used with caution in the condition assessment of aged water pipes especially for grey cast iron pipes.

Owing to continuous economic growth, an increased standard of living, and improvements to health care in Korea, the life expectancy of Koreans rose from 69.0years in 1985 to 71.3 years in 1990 It continued to rise throughout the 1990s, and, by2002, had reached 76.5 years for the general population and 80.0 years for Korean females. Similarly, the percentage of the Korean population that is 65 years of age or older Increased from 3.1 In 1970 to 7.1 In 2000, and is expected to reach approximately14.0 in 2019. Thus, according to this estimate, Korea will have evolved from an 'aging society 'to an "aged society" in only 19 years. In the case of other countries, this same transformation has generally taken 2 to 5 times longer. One of the major issues related to Korea's rapid1y aging population relates to the health problems of the elderly According to the 2002 National Health Survey Report,87.6 percent of the elderly were reported to have at least one chronic disease. In other words, almost 9 out of evert 10 elderly persons in Korea were suffering from a chronic illness. This, clearly, places a significant economic burden on Korean society in the form of increased health care costs. This paper examines the increasing prevalence of chronic diseases within Korea's rapidly aging population and offers some possible short- and long-term solutions to cope with the increased burden being placed on Korea's health care system. These Include the basic services at local health centers for the elderly and the national life-long health promotion programs that aim to correct unhealthy behavior, such as smoking, the excessive use of alcohol, and poor eating and exercise habits.

Objectives: This study examines the status of iodine intake and compares the characteristics (region and thyroid disease prevalence) according to the iodine-sourced food intake pattern in Chinese adults. Methods: An online survey was conducted by enrolling 437 Chinese adults aged 18-65 years, living in three regions with different iodine nutritional statuses: Sichuan, Chongqing, and Guangdong. Results: The prevalence of thyroid diseases in Sichuan, Chongqing, and Guangdong were 12.5%, 8.5%, and 2.8%, respectively. Conversely, the proportion of people who received thyroid disease-related examinations was a mere 37.5%. Among the subjects who underwent thyroid examination, the prevalence of thyroid disease in the three regions was 32.2%, 21.8%, and 8.0%, respectively. No differences were obtained in the total iodine intake by region, but the type of iodine source foods differed. Regardless of the region, the highest iodine content was obtained from seaweed. However, the iodine content from iodized salt and other foods differed significantly by region. Factor analysis revealed three food intake patterns according to the iodine food source. The study further determined regional differences and differences in the prevalence of thyroid disease according to food intake patterns. Conclusions: High salt intake can also increase iodine intake, which is thought to have an effect on the occurrence of iodine-excess thyroid disease. Hence, efforts focused on improving salty eating habits need to be implemented.
