Abstract	Abstract Emotional arousal is known to enhance episodic memory in young adults. However, compared to valence, little is known about how healthy aging impacts arousal-enhanced memory effects. Furthermore, while emotion regulation is believed to improve with age, it is unclear how individual differences in emotion regulation influence arousal-enhanced memory. In this large-scale online study, we investigated the impact of age and individual differences in emotion regulation on arousal-enhanced memory. During encoding, participants made arousal ratings about negative, neutral, and positive images, and we compared their subsequent memory of high and low-arousal images. We found the impact of emotional arousal on memory was reduced with age, especially for older adults who habitually suppress their emotions. Our findings show that arousal-related memory benefits are reduced with advancing age, and that individual differences in habitual usage of emotion regulation impact these age-related alterations.

Abstract	Objective: To demonstrate that a T2 periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) technique using deep learning reconstruction (DLR) will provide better image quality and decrease image noise. Methods: From December 2020 to March 2021, 35 patients examined cervical spine MRI were included in this study. Four sets of images including fast spin echo (FSE), original PROPELLER, PROPELLER DLR50%, and DLR75% were quantitatively and qualitatively reviewed. We calculated the signal-to-noise ratio (SNR) of the spinal cord and sternocleidomastoid (SCM) muscle and the contrast-to-noise ratio (CNR) of the spinal cord by applying region-of-interest at the spinal cord, SCM muscle, and background air. We evaluated image noise with regard to the spinal cord, SCM, and back muscles at each level from C2-3 to C6-7 in the 4 sets. Results: At all disc levels, the mean SNR values for the spinal cord and SCM muscles were significantly higher in PROPELLER DLR50% and DLR75% compared to FSE and original PROPELLER images (P < .0083). The mean CNR values of the spinal cord were significantly higher in PROPELLER DLR50% and DLR75% compared to FSE at the C3-4 and 4-5 levels and PROPELLER DLR75% compared to FSE at the C6-7 level (P < .0083). Qualitative analysis of image noise on the spinal cord, SCM, and back muscles showed that PROPELLER DLR50% and PROPELLER DLR75% images showed a significant denoising effect compared to the FSE and original PROPELLER images. Conclusion: The combination of PROPELLER and DLR improved image quality with a high SNR and CNR and reduced noise. Advances in knowledge: Motion-insensitive imaging technique (PROPELLER) increased the image quality compared to conventional FSE images. PROPELLER technique with a DLR reduced image noise and improved image quality.

Abstract	Colloidal quantum dots (QDs) are widely regarded as advanced emissive materials with significant potential for display applications owing to their excellent optical properties such as high color purity, near-unity photoluminescence quantum yield, and size-tunable emission color. Building upon these attractive attributes, QDs have successfully garnered attention in the display market as down-conversion luminophores and now venturing into the realm of self-emissive displays, exemplified by QD light-emitting diodes (QD-LEDs). However, despite these advancements, there remains a relatively limited body of research on QD patterning technologies, which are crucial prerequisites for the successful commercialization of QD-LEDs. Thus, in this review, an overview of the current status and prospects of QD patterning technologies to accelerate the commercialization of QD-LEDs is provided. Within this review, a comprehensive investigation of three prevailing patterning methods: optical lithography, transfer printing, and inkjet printing are conducted. Furthermore, several exploratory QD patterning techniques that offer distinct advantages are introduced. This study not only paves the way for successful commercialization but also extends the potential application of QD-LEDs into uncharted frontiers.

Abstract	Aims and objectives: To examine the effects of registered nurse staffing levels, work environment and education levels on the residents' quality of life and nurses' job dissatisfaction, burnout and turnover intention. Background: Registered nurse staffing status and work environment are suboptimal in nursing homes worldwide. Nursing home care aims to maximise residents' quality of life. However, evidence on the impact of registered nurse staffing levels, work environment and education levels on the residents' quality of life and nurse outcomes in nursing homes is limited. Design: This is a cross-sectional observational study. Methods: A total of 513 residents and 117 registered nurses from 39 nursing homes in South Korea participated in surveys. The main measures included registered nurses' staffing levels, work environment, education levels, residents' quality of life, registered nurses' job dissatisfaction, burnout and turnover intention. We analysed data using the generalised estimating equations and reported the study using the STROBE checklist. Results: Overall, the residents' quality-of-life score was 13.7 ± 2.6 (out of 17). Residents in nursing homes with a higher number of registered nurses or with work environment evaluated as 'mixed' or 'better' (compared with 'poor') had a higher quality of life. Regarding nurse outcomes, 74.4% of the registered nurses were dissatisfied with their current jobs, 12.0% had burnout and 18.8% had a turnover intention. Registered nurses working in 'mixed' or 'better' work environment were less likely to have job dissatisfaction. Registered nurses' education levels did not have a statistically significant effect on the resident and nurse outcomes. Conclusions: Registered nurse staffing levels and work environment should be considered important for improving residents' quality of life and nurses' job satisfaction. Relevance to clinical practice: Regulation and policy reforms are needed to increase the registered nurse staffing levels and to create a good work environment in nursing homes. Patient or public contribution: Nursing home residents and registered nurses participated in the surveys of this study. Registered nurses facilitated resident recruitment by identifying and introducing the study to residents who were eligible for study participation. Trial registration: Not applicable.

Abstract	When we update our episodic memories with new information, mnemonic competition between old and new memories may result because of the presence of shared features. Behavioral studies suggest that this competition can lead to proactive interference, resulting in unsuccessful memory updating, particularly for older adults. It is difficult with behavioral data alone to measure the reactivation of old, overlapping memories during retrieval and its impact on memory for new memories. Here, we applied encoding-retrieval representational similarity (ERS) analysis to EEG data to estimate event-specific encoding-related neural reinstatement of old associations during the retrieval of new ones and its impact on memory for new associations in young and older adults. Our results showed that older adults' new associative memory performance was more negatively impacted by proactive interference from old memories than that of young adults. In both age groups, ERS for old associative memories was greater for trials for which new associative memories were forgotten than remembered. In contrast, ERS for new associative memories was greater when they were remembered than forgotten. In addition, older adults showed relatively attenuated target (i.e., new associates) and lure (i.e., old associates) ERS effects compared to younger adults. Collectively, these results suggest that the neural reinstatement of interfering memories during retrieval contributes to proactive interference across age, whereas overall attenuated ERS effect in older adults might reflect their reduced memory fidelity.

Abstract	Objectives: Based on socioemotional selectivity theory, one might predict that older adults' well-being would be less negatively affected by coronavirus disease 2019 (Covid-19)-stress, as with other stressors, than younger people. However, whether sleep quality, which is negatively affected by aging, is similarly protected from the negative consequences of Covid-19-stress with age is unknown. Here, we examined the association between Covid-19-stress, above and beyond general-stress, and sleep quality and how it varies by age. Method: From December 2020 to April 2021, 386 adults reported their Covid-19-stress, sleep quality, and resilience in an online study. Results: While older age was related to lower Covid-19-stress, Covid-19-stress was associated with worse sleep quality with greater age. Discussion: These results suggest that at least some aspects of one's well-being may be more susceptible to the negative consequences of stress with increasing age. Our results might be better understood via the strength and vulnerability integration model, which posits that older adults have increased susceptibility to prolonged and unavoidable stress.

Abstract	Objective: This study aimed to explore young breast cancer survivors' experiences of peer support activities and their need for a metaverse-based peer support program. Methods: This qualitative content analysis study involved 15 young women with breast cancer under the age of 40. Participants with diverse experiences in peer support activities were purposefully selected. Data were collected in March 2023 through three focus group interviews and three additional individual interviews. Saturation was reached when no new themes emerged from the interviews. The interviews were transcribed verbatim and analyzed using conventional content analysis. This study ensured the trustworthiness of the data based on criteria including truth value, applicability, consistency, and neutrality. Results: Four categories emerged: advantages, disadvantages, preferences for peer support activities, and the need for metaverse-based peer support programs. Participants valued peer support activities for exchanging information, nurturing empathy, and encouraging healthy behaviors. Challenges included information confusion, peer conflict, isolation, and stigma. Preferences for group composition, size, and medium varied; however, all participants agreed on the importance of operational guidelines. Participants expected a metaverse-based peer support program to provide safe and enjoyable experiences despite concerns about unfamiliar platforms. Conclusions: This study highlights the unique needs and preferences of young breast cancer survivors regarding peer support activities. Well-organized and tailored peer support can significantly enhance their quality of life. These findings provide valuable insights for developing effective metaverse-based peer support programs to meet the needs of young women with breast cancer.

Abstract	Objective: Women diagnosed with breast cancer under the age of 40 face distinctive physical and psychosocial challenges resulting from the disease's pathological features and the developmental aspects associated with their youth. This study aims to investigate the lived experience of breast cancer among this group of young women. Methods: Participants were purposefully selected from online communities and chat rooms in South Korea. A total of 15 young women with breast cancer were included in this study, and data were gathered through three focus group interviews. The interviews were transcribed verbatim and analyzed using the hermeneutic phenomenology method. Results: Four essential themes emerged based on four lifeworld existentials: lived body, lived time, lived space, and lived others. These four essential themes were: a wounded and sick body, life robbed of youth and elderly years, crossroads of growth discovered at life's extremes, and a steadfast companion on a solitary journey. Conclusions: Young women with breast cancer face unique challenges due to the intersection of a severe illness and its impact during their formative years. This study offers valuable insights for crafting customized interventions that directly target the physical and psychosocial requirements of young breast cancer survivors, ultimately enhancing their quality of life.
