Objectives: This study explores the impact of age groups on social presence and trust among users of medical artificial intelligence chatbots. Furthermore, we investigate the existence of gender differences within these relationships. Method: We collected data through a survey from people who had interacted with general hospital chatbot services, either by making reservations or seeking consultations. Multiple linear regression analysis was conducted to examine the relationship between general characteristics of study population and social presence and trust of artificial intelligence chatbots. Additionally, we conducted stratified analysis to confirm the presence of gender differences within these relationship. Results: Among 300 participants, those aged 50 and older had higher social presence of artificial intelligence chatbots and greater trust of artificial intelligence chatbots (social presence, 𝛽=0.543, p=0.003; trust, 𝛽=0.787, p=0.000). In stratified by sex, women aged 50 and older had higher social presence and trust of artificial intelligence chatbots compared to those in their 30s age group (social presence, 𝛽 = 0.925, p=0.002; trust, 𝛽=0.645, p=:0.007). However, there was no statistically significant relationship between age and chatbot social presence and trust in men. Conclusion: This study demonstrates that advanced age plays a significant roles in users' social presence and trust in medical artificial intelligence chatbots. Futhermore, our findings reveal gender differences with women aged 50 and older showing the most substantial levels of social presence and trust. Therefore, it is expected that this finding can serve as valuable evidence to enhance the satisfaction of medical institution service users, offering crucial insights into the effective utilization of chatbot services.

The purpose of this research is to analyze priority of the elderly user interface (UI) evaluation criteria based on user's lifestyle. Since the elderly population will occupy over 20% of the all Korean population in the near future, we need to know older users' needs and information because elderly users will be main customers in the super-aged society. This paper investigated the definition of elderly users and characteristics demographically, socio-economically, and physically/cognitively. A total of 238 questionnaires from older users were analyzed based on a segmentation table for the elderly developed by the previous study. According to factor analysis and cluster analysis, 6 types of lifestyle and 4 groups of the elderly users were classified, respectively. The priority of UI evaluation criteria for large electronic home appliances and mobile products was analyzed by analyses of variance (ANOVAs). The results indicated that the priority of (physical, emotional, and cognitive) UI criteria was significantly different among elderly users' lifestyles for both home appliances and mobile products. Consequently, the results of this study may help the company develop some competitive silver products and give higher satisfaction to the elderly users by suggesting different priority of UI evaluation criteria according to the target elderly group. The results may also contribute to revitalize national economy by significantly increasing senior market shares.

Background: The purpose of this study was to identify the status of Successful Aging among the elderly aged 65 and over in rural areas and to compare factors related with Successful Aging between "kyung-ro-dang" users and non-users. Methods: A total of 181 elderly aged 65 or older were selected from four districts (Heung-upri, Mejiri, Sajerri, and Daeanri) of Wonju city. A survey method using face to face interviews was applied to collect information. Successful aging was measured on a 5-point Likert-type scale using the successful aging scale developed for the Korean elderly, which indicates the higher the score, the higher the level of successful aging. Descriptive statistics, bivariate, and multivariate analyses were computed; the level of significance was set at 5%. Hierarchical polynomial regression was applied to find out the factors associated with successful aging. Results: Of the total, 112 elders used kyung-ro-dang and 69 elders who did not use kyung-ro-dang. The level of successful aging of the elderly was higher among kyung-ro-dang users than non-users. The factors related to successful aging among kyung-ro-dang users were walking and social participation. Users who walk more than 4 times per week and social participation activities have a higher level of satisfaction. In the case of non-users, a higher level of monthly income, having a spouse, social support, and social participation associated with a higher level of successful aging. Conclusion: Monthly income, social participation, and social factors were found to be related to successful aging along with physical and mental health conditions among the elderly in rural areas. Therefore, it can be concluded that income, social as well as mental and physical factors, are more critical for successful aging in the rural community care in Korea.

This study was carried out to present design guidelines for developing electric bikes which could be used for more users regardless of gender and age. Through a survey with 336 male and female respondents in Seoul aged between 10s and 70 years or older, the convenience of bicycle use and image preference by gender and age were investigated. To evaluate convenience of bicycle use, the 7 principles of universal design made by Universal Design Center were customized to fit for accessing bicycles. The following are results of statistical analysis on 301 valid data: (1) of the 7 principles, conventional bicycles were identified to be the most inconvenient in principle 6(low physical effort), followed by in principle 5(tolerance for error) and 7(size and space for approach and use). Women appeared to feel more inconvenience than men in all evaluation criteria while using bicycles. The relation between the convenience of use and users' age was not identified. (2) Preferred images by bicycle users turned out to be those of 'simple' and 'light.' By gender, male preferred more 'technical' and 'dynamic' images than female. By age, users in their 10s-20s preferred more 'individual' image than 70 years or older.

Objectives: This study was undertaken to evaluate the intake of vitamins and minerals from dietary supplements (DSs) in Korean adults and elderly. Methods: Data for this study was generated from the 2017 Korea National Health and Nutrition Examination Survey (KNHANES). We analyzed 4,204 individuals aged 19 years and older (2,579 users and 1,625 non-users). The survey included 24-h recall questions on food and DS intakes, as well as questions on DS use over the past year. The nutrient DSs evaluated were calcium, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, and vitamin C. Total nutrient intakes were obtained by combining nutrient intakes of foods and DSs consumed by each subject. Results: Most micronutrient intakes from food (except for thiamin) in adult users, and the four micronutrient intakes (iron, vitamin A, vitamin B₂ and vitamin C) in elderly users, were significantly higher than values obtained in non-users. For total intake of nutrients and DSs, both adult and elderly users had a significantly higher intake than non-users. While proportions below Estimated Average Requirements for all micronutrients by adding respective DSs in users were significantly reduced in adults and elderly as compared to non-users, the proportions of above Tolerable Upper Intake Levels for calcium and vitamin A in adults, and vitamin A in elderly, were significantly increased. In the total subjects examined, consumption of DSs was associated with lower odds ratios of undernutrition of micronutrients, and with higher odds ratios of overnutrition of calcium, iron, and vitamin A, as compared to non-users of DSs. Conclusions: Although DSs consumption by adults and the elderly improves the micronutrient status, it also increases the risk of excessive intake of certain vitamins and minerals.

고령화가 급격한 속도로 진행되며 발생하는 문제 중 고령 운전자 사고는 해결되어야 하는 중요한 사회문제이며 사고를 감소하고자 하는 노력은 앞으로 맞이할 초고령 사회를 대비하기 위해 꼭 필요하다. 현재 고령자는 65세 이상으로 규정되어 있으며 이에 따라 고령 운전자 사고에 관련된 다양한 연구들은 65세를 기준으로 일반운전자와 고령 운전자를 구분하여 분석한다. 이러한 배경으로 인해 수용 가능한 정확도의 수준에서 실질적으로 교통약자로 분류되어야 하는 신체 능력을 갖춘 고령 운전자를 구분하는 기준은 제시되고 있지 않다. 따라서 본 연구에서는 상관분석을 이용하여 고령 운전자의 연령별 사고특성을 분석하여 연령군집별 사고 위험성을 비교하도록 한다. 분석결과 차종별 주요 사고특성에 대해 75세 이상의 경우 사고 발생에 미치는 영향력이 높아지는 것으로 나타났으며, 70세에서 80세 사이 구간에서 사고 발생 빈도가 상대적으로 낮았던 승용차에 대해서도 주요사고특성을 분석한 결과 75세 이상 84세 이하 구간에서 사고 발생에 대한 영향력이 높아지는 것이 두드러지게 나타났다. 이는 고령화가 진행되고 평균 수명이 늘어남으로써 고령자 구간 폭도 증가하는바, 고령자 내에서도 특성이 나뉘게 되며 본 연구를 통해 연령군집별로 사고 발생에 대한 영향력이 달라지는 것을 확인하였다.
