Purpose: This study aimed to identify the difficulties with end-of-life care (EOLC) experienced by intensive care unit (ICU) nurses and to investigate their educational needs for EOLC. Methods: Mixed methods were used to survey ICU nurses at a university hospital. Quantitative data (N=106) were collected through a questionnaire and analyzed using an independent samples t-test, ANOVA, Mann-Whitney U test and $Scheff{\acute{e}}$ test. Qualitative data (N=19) were collected through focus group interviews and analyzed through qualitative content analysis. Results: The mean score on the difficulty of EOLC was 3.41 out of 5. The education needs derived from the qualitative analysis was categorized into four themes: 1) guidelines on professional EOLC, 2) spiritual care, 3) a program to take care of feelings of patients, families and nurses, and 4) activities to think about death. Conclusion: This study confirmed that ICU nurses were experiencing an extreme difficulty in providing EOLC. In addition, a qualitative analysis confirmed that they needed an EOL nursing program. To mitigate the difficulties experienced by nurses involved in EOLC, there is an urgent need to develop an education program for EOLC tailored to nurses' needs.

The purpose of this study is to analyze the immediate effects of five toed shoes on foot structure. Subjects consisted of 26 college-aged women with pes planus. X-ray analysis of student feet were performed both barefooted and with five toed shoes. Dependent variables were hallux valgus angle, calcaneal inclination angle, 1st metatarsal declination angle, and intermetartarsal angle. Independent t-test was used for statistical analysis along with SAS. Overall, there were statistically significant changes of test subject's dependent variables when wearing five toed shoes. Specifically, the hallux valgus angle decreased, the calcaneal inclination angle and 1st metatarsal inclination angle increased, and intermetatasal angles both increased and decreased, shifting towards normal range. In every case the dependent variables shifted towards a more normal range while subjects wore five toed shoes. This study only examined the immediate corrective effects of five toed shoes on foot structure, but long-term studies are needed to understand the prolonged effects of five toed shoes on foot structure.

The purposes of this study are to investigate the parents' communication behavior with their teen-aged child and the effects of the demographic and socio variables on it concerning with the parent education. A sample of 599 teen-aged children was obtained from the elementary, middle and high schools in the city of Seoul. Mean, t-test and F-test were used for data analysis. The major findings can be summurized as follows : The scores of parents' communication behavior are neither high nor low, namely, are not especially desirable. And there are differences in communication behavior by mother's age and schooling, differences in mother's communication behavior by father's age, schooling and occupation, differences in mother's communication behavior by child' sex and age. According to the above findings, it is necessary for all parents with teen-aged children to have the parental communication education, particularly for father with the older child.

The deteriorated apartments make a social problem in now a days. After all a new alternative plan for deteriorated apartments such as the remodelling concept must be considered. This study aims to survey the needs levels among residents in deteriorated apartments relating to remodelling. It might provide the basic data which could be used for the analysis of consumers in the future implementation of deteriorated remodelling projects. The analytical methods applied for this study were t-test, one-way ANOVA, post-hoc estimation(Scheff test) by the SPSS 10.1 for Windows program. The analysis of the need levels for the areas of remodelling, by the family characteristic variable, residence value viewpoint, and residence satisfaction level, indicated that the demand level for ‘equipment ’was the highest, followed by the order of ‘structure’ and ‘interior’. The need levels for ‘security’, ‘parking lot’, ‘public facilities in apartment block’, and ‘landscape’ were generally low but in the group of high income, the need levels were comparatively high.
