This study investigated the relationship among pain, depression and activities of daily living in nursing home residents. Data was collected through a structured questionnaire survey of residents at 4 nursing homes in S city. The measures were the Numeric Rating Scale (NRS) and Discomfort Scale-Dementia of the Alzheimer Type (DS-DAT) for self-reported and observational pain, Geriatric Depression Scale Short Form-Korea Version (GDSSF-K) for depression, Barthel Activities of Daily Living (BADL) scale for ADL. The data were analyzed using the Pearson's correlation coefficient and hierarchical multiple regression using the SPSS/PC 20.0 program. The analysis results of the relationship of pain, depression and activities of daily living, both DS-DAT and NRS showed a significant negative correlation with the activities of daily living and a positive correlation with depression. Finally, gender, arthritis, depression, and activities of daily living explained 28.1% of the variance in pain using NRS, whereas depression and activities of daily living explained 21.5% of the variance in pain using DS-DAT. The results highlight the need to develop a pain management program that reduces the depression and promotes the activities of daily living in nursing home residents; hence, a differentiated approach as non-pharmacological interventions is required.

This study examined whether any differences can be found in desirable character traits and creative personality characteristics depending on the appearance management behaviors of male and female adolescents in Gwangju, South Korea. It was conducted by administering a self-report survey to 544 male and female middle school students. The collected survey data were analyzed by Means, Cronbach's ${\alpha}$, Factor analysis, One-way ANOVA, and Duncan-test using the SPSS/PC WIN 19.0 statistical program. The results were as follows: According to the results of the survey, total coordination seeking in appearance management behavior is very important to teens and is deeply related to desirable character traits and creative personality characteristics. Desirable character traits show positive results for basic living habits, filial piety, respect and affection. Creative personality characteristics show positive results for curiosity, open thinking, risk taking, assignment completion and esthetic appreciation. Considering these findings, there is a need for supplementary content on total coordination seeking behavior in home economics courses. Positive effects in terms of desirable character traits and creative personality characteristics can be expected through after class activities involving clothing habits or searching for a path in life and given the depth of education related to total coordination through a free semester system.

With the growing proliferation of mobile computing devices, several industrial and academic research groups have a vigorous studying to remote control for various appliances with mobile devices such as Notebooks, PDAs, and Smartphones in home network environments. We can utilize the good points of mobile devices such as portability and usability so that we can remote control and manage the mobile devices connected on home networks anytime, anywhere. However, mobile devices use different languages. Therefore, they cause some problems because their interfaces and the methods of operation are different each other. To solve these problems, there are two consideration. First, we may be solved development of the user interface and difficulty of maintenance in order to control various heterogeneous devices. Second, we may provide the user interface which is dynamically adapting user's preferences and device characteristics. To satisfy these considerations, we describe the design of an adaptive user interface for home network environments using the UIML (User Interface Markup Language) based on XML (eXtensible Markup Language) and the profile information of the user and device. Therefore, we present several implementation examples that show how the framework can form the basis of prototypical applications.
