Purpose: This study was designed to systematically explore and elicit information about terminally ill cancer patients' and primary family caregivers' subjectivity of death. Method: Using Q-methodology, 21 terminally ill cancer patients and 19 primary family caregivers sorted 40 statements during personal interviews. Results: The results of this study show that terminally ill cancer patients have four factors ('Attachment to life', 'Hope for heaven', 'Resignation to reality', 'Avoidance of pain') of response and primary caregivers have four factors('Dependence on religion', 'Faithfulness to reality', 'Obedience to fate', 'Agony of reality'). Comparing the subjectivities of death of terminally ill cancer patients and primary family caregivers, 'Hope for heaven' and 'Dependence on religion' reveal the similarities of their outlook. On the other hand, 'Attachment to life', 'Resignation to reality', 'Avoidance of pain', 'Faithfulness to reality', 'Obedience to fate', 'Agony of reality' reveals different aspects of their outlook. The group of terminally ill cancer patients and their families divided into four types. Type A was 'Attachment to life and Agony of reality', type B was 'Attachment to life and Obedience to fate', type C was 'Hope for heaven and Dependence on religion' and type D was 'Resignation to reality and Faithfulness to reality'. The positive group was C or 'Hope for heaven and Dependence on religion'. Conclusion: There are significant differences found in the subjective structure of death among terminally ill cancer patients and primary family caregivers. Therefore, it is necessary to develop an individualized nursing intervention for terminally ill cancer patients and family caregivers.

Purpose: This study was to identify the effects of self-resilience and social support on reality shock among new graduate nurses. Methods: The data was collected using self-reported questionnaires from a convenience sample of 111 new graduate nurses. The data was analyzed by descriptive statistical, independent t-test, ANOVA, Scheffe test, Pearson correlation coefficient, and multiple regression via the SPSS Window 23.0 program. Results: Among general and work related characteristics, factors that have shown significant differences on reality shock were gender (t=-2.29, p=.024), work unit (t=3.31, p=.023) and whether they are working at unit they desired (t=-5.08, p<.001). Reality shock has shown a negative correlation with self-resilience (r=-.51, p<.001) and social support (r=-.41, p<.001). Factors that affected the reality shock on new graduate nurses were self-resilience (${\beta}=-.43$, p<.001), whether they are working at unit they desired (${\beta}=.35$, p<.001) and their currently work unit (${\beta}=-.17$, p=.028). These factors take into account of 38.0% of overall reality shock. Conclusion: The results suggest that self-resilience, desired unit and current work unit should be considered as factors when developing an intervention to alleviate the reality shock experienced by new graduate nurses.

The purpose of this study was to investigate false belief understanding and justification reasoning according to information of reality amongst children aged 3, 4 and 5. Children aged 3 to 5 years (N = 176) participated in this study. Each child was interviewed individually and responded to questions designed to measure his/her false belief understanding. Every child responded to the false belief task under two different information conditions of reality(reality known vs reality unknown). For more specific analysis, children's reasoning responses were also recorded. The major findings of this study are as follows. Children could understand false belief more easily under reality unknown conditions. Specifically, the influences of information conditions were crucial to 3-year-olds but not to 4- and 5-year-olds. Although 3 year olds were able to avoid the systematical errors inherent in the false belief task, they still did not understand the false belief itself. This study provides specific aspects of false belief understanding and its relevance to general changes in cognitive development.

Visualized information platforms through building information modeling (BIM) such as virtual reality (VR) and augmented reality (AR) improves the efficiency of architectural information exchange. Despite that, less effort has been directed to evaluate the effectiveness of different BIM visualization platforms for architectural design review. This study fills these gaps and compares three BIM visualization tools for reviewing diverse architectural review factors and technology acceptance degree. Three main BIM visualization tools, which are desktop-based, virtual reality-based and augmented reality-based, were employed and different architectural review factors and user's technology acceptance degree was measured. As a result, VR and AR environment showed better visual presentation than desktop environment during design review. In terms of the technology acceptance level, VR and AR environments have received higher ratings compared to desktop environments. The detailed findings provide guidelines for participants and researchers involved in design review process to selectively adopt VR and AR system to various architectural design review components.
