For more efficient energy management of nodes in wireless sensor networks, research has been conducted on mobile sink nodes that deliver data from sensor nodes to server recently. UAV (Unmanned Aerial vehicle) is used as a representative mobile sink node. Also, most studies on UAV propose algorithms for calculating optimal paths and have produced rapid advances in the IoD (Internet of Drones) environment. At the same time, some papers proposed mutual authentication and secure key exchange considering nature of the IoD, which requires efficient creation of multiple nodes and session keys in security perspective. However, most papers that proposed secure communication in mobile sink nodes did not protect end-to-end data privacy. Therefore, in this paper, we propose integrated security model that authentication between mobile sink nodes and sensor nodes to securely relay sensor data to base stations. Also, we show informal security analysis that our scheme is secure from various known attacks. Finally, we compare communication overhead with other key exchange schemes previously proposed.

In this study, users of the display system designed for the conference hall were evaluated as an example of a temporary space marking system for vaccination at a COVID-19 vaccination center in Chuncheon, Gangwon Province.Unlike ordinary space, temporary space display systems organize space on a limited schedule, so it is necessary to properly place and communicate information about space and processes in the display design to users. Therefore, a paper description manual, a wall display panel, and a floor path tape were provided and deployed to users of the inoculation session. The results of user evaluations show that for specific users over 60 years of age, a file (information display system) that conveys the overall information about the space and process is effective for vaccination. This result is expected to serve as a reference to how and how the display system will be installed in a temporary space in the future.

Purpose : Community care occupational therapy is an integrated mediation method such as evaluating and mediating daily life activities, evaluating and modifying the environment, and providing information by visiting the home where the client resides. In this study, we examine the effect of implementing a community-care occupational therapy program on the levels of depression, quality of sleep, and quality of life of elderly individuals living alone. Methods : Among the users of organizations C and D located in City B, province A, South Korea, a total of 32 elderly citizens aged above 65 were chosen as the study subjects and randomly divided into an experimental group and a control group. For the experimental group, a total of 24 sessions, each lasting 60 minutes, comprising a community-care occupational therapy program and each organization's own program, were conducted, with each session conducted twice a week for a total of 12 weeks. On the other hand, those in the control group participated in the existing programs of their organizations. Changes in the levels of depression, quality of sleep, and quality of life before and after the intervention were compared using the GDSSF-K, GQOL, and GQOL. Results : Overall, the levels of depression, quality of sleep, and quality of life were found to improve among the experimental group after the intervention. In a between-group comparison of the changes before and after the intervention, the experimental group was found to exhibit a more statistically significant difference than that of the control group. Conclusion : The results obtained in this study confirm that community-care occupational therapy programs have a positive effect on the levels of depression, quality of sleep, and quality of life of elderly individuals living alone.

Objectives: The purpose of this study is to examine the marital status, drinking behavior, and mental health characteristics of alcohol consumers, and to explore the relationship between marital status and mental health among alcohol consumers. Methods: The research data utilized raw data from the 8th Korea National Health and Nutrition Examination Survey (2020), Second Round. A total of 3,713 participants were included in the final analysis. Data analysis was performed using the statistical software SPSS version 26.0. Results: The relationship between the study participants and mental health revealed that compared to those with a spouse, individuals who were divorced or separated had an odds ratio (OR) of 2.598 for 'depression' and an OR of 2.142 for 'suicidal thoughts'. In the case of 'stress perception', individuals who were divorced or separated had an OR of 3.434. In terms of gender, females had an OR of 4.867 for 'depression', an OR of 2.510 for 'suicidal thoughts', and an OR of 1.847 for 'stress perception', compared to males. Regarding age, the odds of 'depression' were 1.801 times higher in the 60 to 79 age group compared to the 18 to 39 age group. For smoking status, smokers had an OR of 2.812 for 'depression' compared to non-smokers. The OR for 'suicidal thoughts' was 3.047, and the OR for 'stress perception' was 1.463. However, the relationship between mental health and binge drinking frequency and quantity of alcohol consumed in a single session was not significant. Conclusion: The divorced, separated, or bereaved groups may be vulnerable to 'depression,' 'suicidal ideation,' and 'stress.'

Objectives: This study investigated the need for nutrition education aimed at improving the health of residents and users of social welfare facilities for persons with disability and aimed to provide basic information for developing a nutrition education program that meets the needs of the field. Methods: Altogether, 249 employees working in social welfare facilities for people with disabilities were included in the study. Data on the health status of residents/users, meal management, nutritional education, nutritional education needs, and awareness of nutritional education were obtained through online surveys. A descriptive analysis was conducted to analyze the demographic characteristics, needs, and perceptions of the respondents, and independent t-tests and χ² tests were performed to analyze and compare the differences between residential and daycare facilities. Results: The majority of residents/users of social welfare facilities for persons with disabilities have developmental disabilities. When educating residents with residents/users of social welfare facilities, 'personal hygiene' was the most necessary topic, followed by 'obesity management' education. Regarding the methods of providing education, face-to-face lectures demonstrated a high demand. They responded that when nutrition education experts provide nutrition education to people with disabilities, they must understand 'the physical characteristics of persons with disabilities' and have the ability to determine appropriate nutrition for such people. The most appropriate nutrition program training would be twice a year, lasting 30 min to 1 h per training session. Conclusions: It will present a direction for operating a nutrition education program for persons with disabilities that meets their needs of social welfare facilities and ultimately contribute to the establishment and activation of nutrition education tailored to welfare facilities for such individuals in Korea.
