Purpose: This paper presents the development process and the final contents of the sellf- management education program integrated with exercise training (Healthy Aging Happy Aging, HAHA program) for community residing older adults with chronic diseases. Methods: The program evaluation methodology was applied which is an interactive program development process based on needs assessment, formative evaluation, process evaluation and outcome evaluation. The program was developed and revised while the program was implementing to 22 hypertension (HT) and 32 diabetic (DM) participants. Results: The final program has two sub-programs for HT and DM participants utilizing self-efficacy resources. They share four common components; 1) health screening of exercise risks, 2) weekly 1-hour group self-management education classes, 3) biweekly 1-hour group exercise training and 4) a mid-term individual counseling. Both sub-programs were 12-weeks long but have different education and exercise contents. Participants-rated mean satisfaction scores were 3.47/4 and 3.61/4 for HT and DM program respectively. Attendance rate were 83.1% ~ 92.3% for the classes. Conclusion: The HAHA program developed by multidisciplinary team which reflected participants needs was accepted well by participants evidenced by high attendance rate and perceived satisfaction level.

This research aims to develop the companion robot experience design for elderly in korea based on needs-function deploy matrix of robot and emotion expression research of robot in multimodal interaction. First, Elder users' main needs were categorized into 4 groups based on ethnographic research. Second, the functional elements and physical actuators of robot were mapped to user needs in function- needs deploy matrix. The final UX design prototype was implemented with a robot type that has a verbal non-touch multi modal interface with emotional facial expression based on Ekman's Facial Action Coding System (FACS). The proposed robot prototype was validated through a user test session to analyze the influence of the robot interaction on the cognition and emotion of users by Story Recall Test and face emotion analysis software; Emotion API when the robot changes facial expression corresponds to the emotion of the delivered information by the robot and when the robot initiated interaction cycle voluntarily. The group with emotional robot showed a relatively high recall rate in the delayed recall test and In the facial expression analysis, the facial expression and the interaction initiation of the robot affected on emotion and preference of the elderly participants.

Purpose: A systematic review and meta-analysis of nutrition educational intervention studies was performed to assess the association between nutrition education intervention and fruit & vegetable (F&V) preferences and nutrition knowledge in preschool children. Methods: The relevant studies of nutrition education intervention and F&V preferences and nutrition knowledge published from January 2000 to June 2020 were located using PubMed, Web of Science, Cochrane Library, Research Information Sharing Service, Korean Studies Information Service System databases, and lists of references. A random-effects meta-analysis was conducted to estimate the standardized mean difference with a 95% confidence interval (CI). Subgroup analyses were performed to identify the association between nutrition education and F&V preferences and nutrition knowledge. Results: The results show that the effect sizes (ES) of F&V preferences and nutrition knowledge of preschool children were 0.31(95% CI, 0.23, 0.39), and 1.69(95% CI, 1.27, 2.12), respectively. The result of subgroup analysis, nutrition education focused on F&V (F&V preferences, ES: 0.32; nutrition knowledge, ES: 2.09) presented a slightly larger effect than general nutrition education (F&V preferences, ES: 0.26; nutrition knowledge, ES: 1.62). As for the type of exposure to F&V, direct exposure education (F&V preferences, ES: 0.40) had a greater effect than indirect exposure (F&V preferences, ES: 0.26). This meta-analysis showed that nutrition education intervention had positive effects on the F&V preferences and nutrition knowledge in preschool children. Conclusion: In conclusion, from the meta-analysis and subsequent subgroup analysis, we found that varied types of nutrition education intervention had varying effects on F&V preferences and nutrition knowledge in preschool children.

This study was conducted in order to examine the effects of horticultural therapy on stress in demented elders, and for this purpose, we analyzed stress-related physiological changes in demented elders under the care of an elderly facility who had not taken medication and consented to blood tests. The horticultural therapy program included only flower decoration, which was preferred by the participants, aiming ultimately to reduce stress. First, a one-to-one session was given for forming rapport and the horticultural therapist had many conversations about plants with the elders. Furthermore, the participants were induced to be absorbed into the horticultural activities, though a short while, so that they might forget troubles. Evaluation was made by measuring subjective stress and the blood cortisol hormone concentration before and after the horticultural therapy and examining differences between them. Subjective stress increased from 12.88 to 17.88 in the control group, but decreased significantly from 13.88 before the therapy to 6.38 after in the experimental group (p = 0.007). When the blood cortisol hormone level was measured as a physiological indicator of stress, it decreased significantly from $11.33{\mu}g{\cdot}L^{-1}$ before the horticultural therapy to $9.85{\mu}g{\cdot}L^{-1}$ after (p = 0.037). These results suggest that horticultural therapy reduces the blood cortisol hormone level and is effective in easing stress.

Purpose: The purpose of this study was to examine self-transcendence, life satisfaction, and preference for end-of-life care in elderly patients. Method: This was a descriptive survey study. The study period was between August 2013 and October 2013 and included 208 elderly patients. Results: The average scores for self-transcendence, life satisfaction, and preference for end-of-life care were 2.79, 9.97, and 3.24, respectively. Statistically significant positive correlations were observed between self-transcendence and life satisfaction, decision making by health care professionals, spiritual area, family area. A positive correlation was observed between: (1) life satisfaction and spiritual area, (2) decision making by health care professionals and family area, and (3) decision making by health care professionals and pain area. Self-transcendence was a significant predictor of PCEOL. Conclusion: This study will provide basic information for use in the development of a program to encourage self- transcendence and life satisfaction, as well as to consider the elder's autonomy, pain control, and spirituality as important factors at the end-of-life care.

With the increase in population, the number of such senior citizens is increasing day by day. These senior citizens have a variety of care needs, but there are not enough health workers to look after them. Ambient Assisted Living (AAL) aims at ensuring the safety and health quality of the older adults and extending the number of years the senior citizens can live independently in an environment of their own preference. AAL provides a system comprising of smart devices, medical sensors, wireless networks, computer and software applications for healthcare monitoring. AAL can be used for various purposes like preventing, curing, and improving wellness and health conditions of older adults. While information security and privacy are critical to providing assurance that users of AAL systems are protected, few studies take into account this feature. In this paper, we propose a secure and lightweight authentication scheme for the AAL systems. The proposed authentication scheme not only supports several important security requirements needed by the AAL systems, but can also withstand various types of attacks. Also, the security analysis results are presented to show the proposed authentication scheme is more secure and efficient rather than existing authentication schemes.

The purpose of this study is to suggest the direction of the funeral culture industry suitable for the age of longevity and well-aging through a study on changes in the perception of funeral culture among the elderly. The survey of this paper was conducted by Gallup Korea, and the survey method was a 1:1 individual interview using a structured questionnaire. The survey was conducted from October 1 to October 25, 2021, targeting 127 elderly people over the age of 65 living in Seoul, Incheon, and Gyeonggi-do. The number of valid subjects was 110, and the sampling method used was allocation by sex/age/income level/religion. As a result of the study, as for the change in the perception of funeral culture among the elderly, women preferred cremation to men (p=0.034). It was investigated that the level of income (p=0.004) and religious status (p=0.020) had an effect on funerals while alive. According to the presence or absence of thoughts about death, there was a significant difference in the membership of the mutual aid product (p=0.008) and the intention to return to a religious organization (p=0.004) when a memorial service was held. The results of this study are expected to be usefully utilized in presenting the direction and policy of the funeral culture industry suitable for the age of well-aging in the future.

Korea is rapidly becoming an aging society as much as it takes the first place among OECD countries, and as the life expectancy of Korea gradually increases, the proportion of the elders in society increases. Accordingly, the happiness of the elders is contributed to the overall social atmosphere and happiness, however, the lower quality of life of the elders due to physical, psychological and social changes can be developed into social problems such as depression and rising suicide rate. As a result, there is a social interest in improving the quality of life and satisfaction of the elders, and the senior citizen center is receiving renewed attention as a form of welfare facility that can play a pivotal role in the social activities of the elders. In recent years, efforts to improve the environment of the senior citizen center have been made due to the growing role of it, however, there is a controversy over whether the quality of the indoor environment is user-friendly or not due to the limitations of material resources and human resources. It is considered that the quality of the color environment should be improved in the senior citizen center in the way that the color environment is not only an indoor environmental factor which gives high psychological and mental effects to users but also a way to improve the environmental satisfaction at the lowest cost. Previous studies on the facilities related to the elders have been actively carried out, but they were very sporadic and there was very little information about the color environment in the related laws or in the guideline presented by cities. It is necessary to integrate guidelines that are scattered within a comprehensive range without any specific target in order to grasp the current status of the color environment and to properly evaluate it. In addition, considering that the senior citizen center is an important leisure facility for the elders that functions in a residential area with a nationwide network, the results of this study are expected to contribute to the environmental improvement of existing senior citizen center which will be activated in the future by enabling the improvement of psychological satisfaction of the elders.

Objectives: Immunization program is essential public health service under the national responsibility. One of the immunization service of national immunization program is advertising and public relation service, but research for that was rarely conducted. Therefore we conducted the survey for developing advertising strategy of immunization program in 21th century. Methods: Our study subjects were 242 health workers in immunization service department of 169 health centers and 1,193 carers who visited community health center for receiving immunization service of their children. The major questions were general characteristics of the subjects, perceived importance of immunization program, experience of advertising, knowledge and perception about immunization, and items about advertising strategy. Results: Frequently exposed materials in both health workers and carers were TV, community newspapers, and pamphlets. Health workers had high professional knowledges of immunization and carers had high perceptions for need and importance of immunization. Health workers preferred pamphlets and posters as advertising materials and carerers preferred TV and community newspapers. Both health workers and carers preferred green and yellow as advertising posters' color, active and healthy style of immunization advertising, and positive messages of campaign's slogans. Conclusions: Further researches should be conducted for precising long-term immunization advertising strategy in 21th century, and for this we need to develop advertising materials based on public needs and strategy, and evaluate the materials. The national immunization program should be activated throughout more investment of the budgets and human powers.
