Purpose. The purpose of the study was to identify the factors, which predict care burden perceived by caregivers of elders with dementia. Methods: The participants in this descriptive survey were 92 caregivers who used one of six daycare centers located in Incheon. The data were collected by questionnaires composed of items on general characteristics of the elders and caregivers, care burden, caregiver fatigue, and functional status of the elders. Results: General characteristics of the elders associated with care burden were age, gender, religion, and the presence of a spouse. Features of caregivers related to care burden were education, relationship with elderly, amount of rest, intention to care, monthly family income, and perceived family economic status. There were significant correlations among care burden, fatigue of caregiver and functional status of the elders. In stepwised multiple regression analysis, significant influencing factors were identified as caregiver fatigue, functional status of the elders, intention to care, relationship with the elders, amount of rest and elder's gender. Those variables explained 46% of variance of care burden. Conclusion: Functional status of elders and amount of rest were significant predictors and are supported by other previous studies. Future interventions for caregivers need to be focused on the slowing down of functional status of elders and increasing of number and length of caregiver's rest periods.

Mobile phone users have diversified human factors: their channel orientations are different, and the degrees of unwillingness to communicate vary. We examined the effect of human factors on the use of mobile phone, such as the diversity of mobile phone use, the appropriateness of mobile phone, and the aversion to mobile phone as well as the interpersonal communication network through mobile phone. For our sample we surveyed college students and their family members who are older than 400. We found that the more social presence a mobile phone user gets through the mobile phone, and the more familiar to the mobile phone he/she is, (1) the more diversified is the use of mobile phone service, (2) the higher is the level of acceptance of the mobile phone as an interpersonal communication media, and (3) the lower is the level of aversion to the mobile phone. In contrast, those who have some level of aversion to the face-to-face communication, seem to form very limited interpersonal communication network through mobile phone. Their use of mobile phone is also very limited.

Unlike face-to-face communication, text-based communication by digital media has limitations that non-verbal elements are eliminated and social presence decrease. To overcome this problem, people try to find solutions which visualize emotion and situation by using emoticons, icons, computer language and so on. As most SMS users experience the failure of using emotions on the mobile phone, they need to make up for this point. In this study, we conducted research on the recent mobile fonts situations and surveyed users' perception on SMS fonts as to suggest solutions of expressing and visualizing emotions on the mobile phone, a representative media of personal communication. As a solution of reducing the failure, we conducted a survey on users' perception about fonts and the capability of the expressing emotions by fonts. The survey found that mobile fonts can be used as a method to express human emotion. As a finding, the shape of the font can be used as a method to visualize the emotion through text messaging. In future studies, such a method can be applied to variety of different personal media with the communication method based on text. Those studies can propose different usage for fonts in communication.

This study aimed to comprehensively assess the demographic characteristics, health behaviors, subjective health status, health-related restriction of life, and quality of life of male and female elderly aged 65 years older using data from the 2013-2015 Korean Community Health Survey (KCHS). The results showed that compared to the male elderly, the female elderly was less educated, did not have a spouse or had less household income, had poorer health behaviors, and had lower quality of life caused by restrictions in life. The female elderly had significantly lower quality of life than that of the male elderly. Various factors were found to affect quality of life in both sexes. The presence of spouse and BMI did not affect quality of life of men but did affect the quality of life of women. On the other hand, smoking affected the quality of life of men but not of women. Based on these results, more in-depth studies are needed on the female elderly, who have been reported to have lower health-related quality of life, and sex-specific services and programs that could more effectively improve the quality of life among the elderly should also be developed.

In this paper, the prototype of haptic-based NVE (networked virtual environment) QoE (quality of experience) is proposed. The proposed framework plays a role of providing users with realistic feeling by managing the system and network resources efficiently under time-varying networks and heterogeneous systems. Therefore, first IoPH (importance of presence for haptic interaction) is defined to quantitate the sense of real that the users feel now. Then we define the haptic-based NVE components required to satisfy the haptic interaction QoE requirements. Finally, QoE adaptation scheme is suggested, which adapts the haptic-based NVE components to current network and system constraints for better haptic interaction quality.
