Little research has been done to understand the dynamics of well-being among the oldest old, although Korea experiences a rapid increase of this population group. This study explored the effects of demographic characteristics, physical condition, stressful life events and worries on life satisfaction of aged 85 and over. The moderating effects of psychosocial resources in buffering the negative effects of the life events and worries on life satisfaction of this group were also examined. The survey data collected from 213 community residing aged 85 and over was used for analyses. Major findings are as follows. First, most frequent stressors of the oldest old were health related problems. Second, greater worries, higher income status, lower level of physical impairment, co-residence with adult children were significantly related to higher life satisfaction of the oldest old. Third, emotional support from adult children as well as self-esteem of the older persons had buffering effects on the relationship between worries and life satisfaction. According to the results, implications for practice and services to increase life satisfaction of the oldest old were discussed.

Objectives: This study was conducted to identify factors that affect medical service performance in rural health sub-centers and to develop a method to improve health sub-center performance that takes advantage of these insights. Methods: This study included 1,242 South Korean health sub-centers that had been in operation at least since December 31, 2009 as units of analysis. After adjusting for population differences between areas, the performance of medical service among health sub-centers was analyzed according to medical services performed per person. We performed t-tests, ANOVA, Scheffe's tests and multiple regression analyses. Results: The following were significant variables affecting the medical service performance of rural health sub-centers: number of hospitals and clinics, presence of community health practitioner posts, distance from health sub-centers to main public health centers, distance from health sub-centers to the nearest emergency medical facilities, and proportion of the local population aged 65 and over. In contrast, the proportion of the local population between ages 0-4 and the placement of public health doctors that had already completed their internship were not significant variables. Conclusions: The medical service performance of health sub-centers located in rural areas is significantly affected by local population and health care environment characteristics, and therefore, it is imperative to develop strategies to provide differentiated service based on these factors.

Purpose: Purpose of this retrospective study was to investigate cognitive function, physical function, and problematic behaviors of elders who attended dementia daycare centers, and to identify reasons why they stopped using the center. Methods: Participants were 176 elders, 60 years or over, attending one of four dementia daycare centers in Incheon. Data were collected from center documents. Results: Mean age was 80.5 years. When admitted to the centers mean scores for the mini-mental status examination, activity of daily living, and instrumental activity of daily living (IADL) were 12.31, 9.53, and 25.09 respectively. Participants received day care service for an average of 17.98 months. The reasons for leaving the center were worsening dementia and health (40.2%), and problematic behaviors (20.1%). Conclusion: Results show that elders began to use day care services when their cognitive function and IADL had declined considerably. As the ultimate goal of dementia daycare service is to delay the worsening of cognitive capability and decreases in activities daily living, the effect of the service can be maximized when the service is provided as early as possible in the course of progressively severe dementia. Active promotion should be exerted in the community to encourage early use of this service.

Due to the expense of health care and the need to contain costs, many stroke patients are discharged from hospitals while still in an impaired condition. Using Tele-rehabilitation, these patients can receive rehabilitation services remotely. A pegboard is a conventional rehabilitation therapeutic device that integrates cognition, sensation and hand motor function. This study proposes a Tele-rehabilitation content with automated pegboard and shows its functional feasibility. The evaluation of the pegboard session was automated with RFID (radio frequency identification), and a 16-hole pegboard was rapid-prototyped. After a pegboard session is completed, the session result is uploaded to a server automatically for viewing on a web browser by a remote therapist. The therapist can also send messages to remote patients to encourage them or to manage the rehabilitation process.

The purpose of this study was to examine the relationship between depression, perceived health status, and health promotion behavior of frail elderly. The subjects were 164 frail elders aged over 65 registered with the home visiting services of two welfare centers in D city. Data was collected using structured questionnaires from January 2 to February 21, 2020. Data was analyzed using the t-test, ANOVA, Scheffe test, Pearson's correlation coefficients and stepwise multiple regression with the SPSS/WIN 23.0 program. The mean depression score was 10.67, perceived health status was 6.71, health promotion behavior score was 2.59. Health promotion behavior and depression were negatively correlated and perceived health status was positively correlated. Factors influencing health promotion behavior were age, education level, and depression. These variables accounted for 73.6% of health-promoting behaviors. Based on these results, we conclude that it is important to continue health promotion for the frail elderly through various programs including interventions for depression to prevent the elderly from progressing to disability.

The aim of this analysis was to investigate the relationship between the level of safety behavior and the level of oral health behavior among Korean children. Data used in this analysis were from the 2005 Korean National Health and Nutrition Examination Survey (KNHANES). A representative sample of 4,292 children aged from three to eleven years who completed both health interview and health behavior survey. Simple and multiple logistic regression analyses were conducted. All analyses were weighted and SAS 9.1 survey data analysis procedures were used to estimate standard errors accounting for the complex sampling design of the KNHANES. More than seventy percent of children did not keep general safety behaviors except seat on back seat in a car. About seventy five percent of children had experience of preventive oral care during last one year, but about fifty six percent of children brush their teeth twice a day. Socioeconomic status and health behaviors were significantly related in three to six old age group only (p<.05). Generally significant relationship was not found between general safety and oral health behaviors. Among Korean children, general safety and oral health behaviors might be not related each other. Education for general safety behaviors should be underlined for all children. Especially preschool-children with low socioeconomic status need to be educated for healthy behaviors.

Background: We sought to determine the association between chronic pain and participating in routine health screening in a low socioeconomic-status (SES) rental-flat community in Singapore. In Singapore, ${\geq}85%$ own homes; public rental flats are reserved for those with low-income. Methods: Chronic pain was defined as pain ${\geq}3$ months. From 2009-2014, residents aged 40-60 years in five public rental-flat enclaves were surveyed for chronic pain; participation in health screening was also measured. We compared them to residents staying in adjacent owner-occupied public housing. We also conducted a qualitative study to better understand the relationship between chronic pain and health screening participation amongst residents in these low-SES enclaves. Results: In the rental-flat population, chronic pain was associated with higher participation in screening for diabetes (aOR = 2.11, CI = 1.36-3.27, P < 0.001), dyslipidemia (aOR = 2.06, CI = 1.25-3.39, P = 0.005), colorectal cancer (aOR = 2.28, CI = 1.18-4.40, P = 0.014), cervical cancer (aOR = 2.65, CI = 1.34-5.23, P = 0.005) and breast cancer (aOR = 3.52, CI = 1.94-6.41, P < 0.001); this association was not present in the owner-occupied population. Three main themes emerged from our qualitative analysis of the link between chronic pain and screening participation: pain as an association of "major illness"; screening as a search for answers to pain; and labelling pain as an end in itself. Conclusions: Chronic pain was associated with higher cardiovascular and cancer screening participation in the low-SES population. In low-SES populations with limited access to pain management services, chronic pain issues may surface during routine health screening.

The purpose of this study is program development for efficient medical institution management and finding comprehensive measures to increase the credibility of medical institutions. For this purpose, a survey on medical service satisfaction was conducted for elderly people aged 65 or older living in four other areas. The results of the analysis were as follows: First, the survey participants had higher confidence in private medical institutions. Second, there was no relationship between the reliability of public and private medical institutions and the selection of medical institutions. Third, the environment of the survey subjects was related to the selection of medical institutions. The credibility of the surveyed public and private medical institutions affects the selection of medical institutions, and the economic power and understanding of the medical institutions also influence the selection of medical institutions.. Therefore, it is suggested that public medical institutions need to improve the satisfaction of medical services in the future, and management efficiency of public medical institutions in addition to private medical institutions is urgently needed.

A lot of interest in the baby-boomer generation, those who were born after World War II, has emerged since their retirement has been accelerated. The retirement of baby-boomers has caused many health, public welfare, social policy and family relationship problems. However, their increased purchasing power has made them more attractive consumers than any other generation, and they have become a fascinating niche market in the depressed economy. This research selected middle-class women of the baby-boomer generation who have had powerful effects on society and have emerged as an attractive niche market, and attempted to understand their lives intensively. Based on research activities, the purpose of this research is to identify baby-boomer generation middle-aged women's life values. Qualitative research methodology was used to achieve research objectives, and this research aimed to suggest marketing implications to connected industries based on the research results. The research objectives are as follows. 1. understanding the lives of baby-boomer middle-class women who have powerful effects on socio-economic phenomena 2. identifying the life values of baby-boomer middle-class women 3. generating marketing implications based on an understanding of baby-boomer middle-class women's lives and life values This research conducted FGIs(focus group interviews), one of the qualitative research methodologies, to figure out baby-boomer middle-class women's life values intensively and selected 10 women living in Seoul for data collection. The qualitative data of collected FGIs were analyzed with spiral data analysis methodology proposed by Creswell(2007). The most effective factors to influence these middle-class women's lives powerfully were 'time' and 'independence'. Their consciousness of the importance of using time affects their life pattern generally, and their independence also impacts greatly on the way they exploit time and on their diverse relationships. They maximized their self-realization and showed long-term partnership with their surrounding circumstances because of those effective factors. Baby-boomer middle-class women's self-realization was divided into two areas. One was their outside activities and another was perfect management of their physical appearance and home interior. Like the results of this research, their need for social entrance will be reinforced more strongly since their internal and external activities aim for the achievement of self-realization. In addition, this research suggests that baby-boomer middle-class women's activities are connected with their management of their physical appearance and home interior decorations, and that such management is caused not only by a simple interest in fashion and beauty but also a profound desire for self-realization. On account of their consciousness, which is different from other generations, Korean baby-boomer middle-class women are able to maintain positive partnerships with their surrounding circumstances; however, they also show ambivalent emotions to retain effective partnerships. To overcome those stressful situations, they make greater efforts to keep up their health and youth, and also engage in diverse activities to maintain their mental health. Finally, they generate positive attitudes toward their economic situation and extra time to develop self-realization and pursue happy, youthful and healthy lives. Based on those results, this study suggests the following implications. First, industries targeting the baby-boomer generation should develop innovative products and services which help the baby-boomer generation maximize their efficiency of time since time is one of the most important factors powerfully impacting the baby-boomer generation. They will engage in various activities to fill up their extra time and consume helpful products and services. Second, such industries should supply the baby-boomer generation with opportunities which propose new ways of self-realization since this generation shows a great desire for self-realization because of their self-efficacy. With customized strategies of satisfying their needs, the baby-boomer generation would discover opportunities to utilize their abilities, relationships and aesthetic senses, and industries would develop a niche market. Third, market segmentations which target the baby-boomer generation's desire to maintain their physical appearance and home interior should be executed since such activities are the main strategies to develop this generation's self-realization. The baby-boomer generation's desire to study those areas would be expanded, and those education systems should produce innovative products and services targeting the baby-boomer generation. This implication also offers to government officials new policies related with the baby-boomer generation. This exploratory study utilized qualitative research methodology to understand baby-boomer middle-class women's lives, and proposed propositions and limitations for further researches. As for the limitations, first, it is hard to generalize the research results so that they may apply to all areas and economic classes of the baby-boomer generation since this research selected only 10 women living in Seoul for the data collection process. To overcome this limitation, extended data collections of subjects from diverse regions and economic classes should be designed. Second, quantitative research should be conducted to supplement the findings with validities. Third, this research focused on only general ideas of the baby-boomer generation's lives since the range of this study was focused on their overall lives. Therefore, intensive research related to specific areas of their lives should be conducted.
