The purpose of this paper is to pay attention to the problems of the elderly in our society, which is facing an aged society, to understand the lives of the elderly and to recognize the need for retirement and death preparation. It reviews and analyzes the story of So-young, the main character of the movie "Killing Woman," according to the context of the work. The narrative of the film illustrates the problems of suffering for the elderly, such as poverty, disease, dementia, loneliness, and fear of death. In the face of the ultra-aged era, institutional supplementation measures for underprivileged senior citizens at the national level should be established, and social interest and safety nets should be secured, and specific retirement preparations are needed personally. Furthermore, support for research and education of old age preparation education programs and death education programs to prepare for retirement and death should be continuously provided.

For the good combination of high-temperature strength, toughness and creep property, $9-12\%$ chromium steels are often used for gas turbine compressors, steam turbine rotors, blade and casing. In this study, the correlation of microstructural evolution and mechanical properties was investigated fur the specimens heat-treated at 600, 650 and $700^{\circ}C$ for 1000, 3000 and 5000 hrs. The microstructure of as-received specimen was tempered martensite with a high dislocation density, small sub-grains and fine secondary phase such as $M_23C_6$. Aging for long-time at high temperature caused the growth of martensite lath and the decrease of dislocation density resulting in the decrease in strength. However, the evolution of secondary phases had influence on hardness, yield strength and impact property. In the group A specimen aged at $600^{\circ}C\;and\;650^{\circ}C$, Laves phase was observed. The Laves phase caused the increase of the hardness and the decrease of the impact property. In addition, the abrupt growth of secondary phases caused decrease of the impact property in both A and B group specimens.

BACKGROUND/OBJECTIVES: Dietary sugars intake worldwide is stable or decreasing, but overall sugars intake remains above the recommended level. Some studies suggest that ultra-processed foods (UPFs) drive excessive sugars intake. However, UPF consumption in Korea and its association with sugars intake have not yet been studied. This study aimed to estimate the contribution of UPF consumption to total sugars intake and to investigate the association between UPF consumption and total sugars intake in Koreans. SUBJECTS/METHODS: Data from the Korea National Health and Nutrition Examination Survey 2016-2018 were used, and included data on 21,075 participants aged 1+ years completed a 24-h recall. Food items reported in the 24-h recall were classified according to the NOVA system as UPFs, processed foods, processed culinary ingredients, or unprocessed or minimally processed foods. RESULTS: The average daily energy intake was 1,996 kcal, and UPFs accounted for 26.2% of the total energy intake (% TE). The average total sugars intake was 63.1 g (13.0% TE), and 44.9% of total sugars intake came from UPFs. Among the entire population, 15.8% exceeded the recommended limit for total sugars within 20% TE, and excessive total sugars intake was more prevalent among females (19.5%) and children (21.1%). The prevalence of excessive total sugars intake showed a significantly increasing tendency across the quartiles of UPF energy contribution, ranging from 11.9% in the lowest quartile to 23.2% in the highest quartile. Even after adjustment for sociodemographic variables, UPF consumption was positively associated with the prevalence of excessive total sugars intake (P for trend < 0.001). This association was similar in subgroup analyses by sex and age. CONCLUSIONS: This study suggests that UPF consumption may drive excessive intake of total sugars in the Korean diet. Our findings conclusively establish that restricting UPF consumption may be an efficient way to reduce sugars intake in Korean population.

The children who are part of this study are compelled to wear masks at educational facilities for an extended period of time as they continue to be exposed to Asian dust, fine dust, and COVID-19. However, use of masks is currently causing them a lot of inconvenience. This study aimed to gather basic data for the development of a mask that is suitable and comfortable for children to wear. A total of 331 children aged 1 to 9 were investigated through their parents in terms of their lifestyle, mask wearing and purchasing status, mask preferences, mask inconvenience, and mask improvement. According to the survey on mask use, the proportion of children aged 1-3 years old and wearing ultra-small/XS masks, 4-6 year olds wearing small/S, and 7-9 year olds wearing small/S was the highest. More than 80% of children were wearing masks with a standard filter of KF80 or higher. The purchase criteria for children's masks were found to be excellent in terms of wearing comfort and meeting the filter standards. According to the survey on inconvenience of wearing masks, the majority of those surveyed expressed the need to develop children's masks of different sizes. Furthermore, they experienced various kinds of inconveniences from adult masks, such as the material quality and length of earring bands; it was deduced that these aspects need to be taken care of. The vertical folding type was the most popular in the mask design for children. Children have to wear masks for a prolonged period of time, but they are experiencing lot of inconvenience, which need to be addressed.

Korea is the most rapidly aging country in the OECD countries, becoming 'an aging society' in 2010, when over 12% of the population had reached the age 65 and beyond. Along with the population aging, problems of the elderly have become a social issue. Also, the elderly population in most farming villages is increasing due to the cityward concentration of younger generation and the rapid urbanization centered around the capital area. Yet no definite success in revitalization of these villages has been reported despite the acknowledgement of the problems arising from such phenomena. Therefore, by examining "marginal villages" (communities whose joint social activities are difficult to maintain as over 50% of the population is 65 years or older) in Japan, which at this point has entered "the ultra-aged society" before Korea, this study intends to compare and analyze the countermeasure plans for the population decrease in these villages. The case study has been done with the focus on the literary references published in Japan such as papers, various reports, statistics, newspapers, and journals.

This study introduces an effective marketing strategy for fashion SMEs and small designer brands utilizing Instagram as a social networking platform. The research compared the impact of two information delivery types (native advertisements vs. live streaming after native ads) and two types of promotional messages (scarcity vs. price discount) on SNS consumption value, and product attitude toward fashion designer brands. The study involved surveying 251 Korean women aged 25-55 with experience in buying designer products and using SNS. Data analysis was conducted using SPSS 26.0 and Process Macro v3.5. Results indicated that both native advertisements and live streaming enhance economic and social values in SNS consumption. Live streaming with price discount messages generates higher perceived SNS consumption values compared to scarcity messages. Consumers showed a more favorable attitude toward designer brand products when watching the live streaming of price discount messages rather than scarcity messages. The findings emphasize that the broadcast host actively induced participation to reveal viewers' social presence through comments or emphasized discount messages such as ultra-special prices during live streaming on Instagram.

A survey was carried out to investigate the breastfeeding knowledge, breastfeeding rates ultra related factors among women in Seoul and the Chungbuk area, in order to obtain baseline data for the development of an education program on breastfeeding. Subjects included 671 lactating mothers who visited public health or pediatric centers, between December, 1999 and February, 2000 and were interviewed using a questionnaire. The results are as follows: In the breastfeeding knowledge, most of the subjects (93.4%) know correctly that 'breastfeeding is better for a baby's emotional development than formula feeding,'whereas only half of the subjects (51.7%) answered correctly the question on whether 'formula is more nutritious than breastmilk.'The breastfeeding rates were about 57%, 40%, 33% and 12%, respectively for baby's aged 1, 3, 6, and 12 months. These results showed that the breastfeeding rate rapidly decreased with the baby's age. Lower breastfeeding rates were associated with high educational level (college graduate and above), high income, mothers'employment, no experience of attending breastfeeding education programs, and no planning on breastfeeding prior to pregnancy. There was a significant relationship between the level of knowledge and breastfeeding practice; the higher the knowledge score, the higher the breastfeeding rate. In conclusion, an education program should be developed and offered for each low breastfeeding rate group, in order to promote breastfeeding.

Rubber products are aged like human complexion by the attack of oxygen, ultra violet, ozone, etc.. Aging is very important and also very complicated phenomenon to understand. This may explain the rarity of papers on this subject. In this study, we tried to understand the aging behavior of EPDM compared to that of natural rubber. We also compared the sulfur vulcanized system to the peroxide vulcanized one. In our experiment, the peroxide vulcanizates were more advantageous in aging than the sulfur vulcanizates. The authors belived that this study about the high performance EPDM would be applicable to rubber industry.

PURPOSE: The law pertaining to medical service technologists does not discuss the scope and limits of doctors' guidelines. My paper aims to discuss these topics. METHODS: This study was based on a review of literature and an analysis of judicial precedents. RESULTS: Physical therapists have often noted the need for independent practitioners in their articles on health care. Their continued discussions on professional and educational differences have centered round this issue, but their ideas have not been accepted. Practitioners have continued to interpret doctors' guidelines in hospitals without discussing their scope. However, the Supreme Court presented a meaningful decision outlining the conceptual limits and the scope of medical practice. The court suggested, basing its interpretation in the goal of clarifying the concept of medical activities smoothly, was to follow a specific judgment on the levels of education, testing, and professionalism. CONCLUSION: The role of physical therapists is expanding in this country, in order to meet the needs of the ultra-aged society. Education is already responding to rising training needs. By dividing the doctors' guidelines into indirect and direct types, if there's no medical risk near or around the health center or hospital, it is a good idea to allow the management of physical therapy partially, while understanding the scope and limitations of these guidelines clearly. A teleological interpretation of the law is especially relevant, and can be implemented immediately by the authoritative interpretation on part of the health authorities without any legal amendments.

Purpose: This study focused on the societal changes associated with the entry into an ultra-aged society and the increase in single-person households. The core objective of this research is to investigate how social intelligent robots can bring about positive changes in the lives of individuals in single-person households and how such changes influence user satisfaction and the intention to use these robots. Methods: The study employed a cross-sectional analysis using a structural equation model. A survey designed to assess the impact of social intelligent robots' characteristics, such as perceived encouragement, empathy, presence, appearance, and attachment, on user satisfaction and usage intentions was conducted. Data were collected from a total of 335 users and analyzed using the structural equation model. Results: In the characteristics of social intelligent robots for single-person households, it was found that empathy, presence, and attachment significantly influenced satisfaction, while perceived encouragement, empathy, and attachment significantly influenced usage intentions. The research results indicate differences between enhancing user satisfaction and increasing the intention to use social intelligent robots. The findings suggest the essential need for a user-centric approach in the design and development of social intelligent robots. Additionally, it was observed that emotional support plays a crucial role in users' experiences with social intelligent robots. Conclusion: This study verified the impact of social intelligent robots on satisfaction and usage intentions based on users' experiences. It examined the influence of linguistic, visual, and personal characteristics of robots on user experiences, providing insights into how technological and human aspects of social intelligent robots interact to shape user satisfaction and usage intentions. Consequently, the study confirmed that social intelligent robots can bring positive changes to human life, emphasizing the necessity for the advancement of robot technology in a human-centric direction.
