Abstract	Objectives: This study investigated the residential, area-specific prevalence and associated factors of suicidal ideation among adolescents in South Korea, based on nationally representative data. Methods: A secondary analysis was performed using the database of the 17th Korean Youth Health Behavior Survey, which contained data from 54,848 adolescents. Results: Female adolescents (more influential in counties), low economic status (more influential in metropolitan cities), perceived stress (more influential in metropolitan cities), depression (more influential in counties), loneliness (more influential in counties), and anxiety (more influential in counties) were influencing factors in all areas, and the factors associated with suicidal ideation differed by residential area. The factors related to suicidal ideation were similar by residential area, but the degree of relevance differed from area to area; in particular, the prevalence of variables related to mental health (depression, loneliness, and anxiety) was high in counties. Alcohol drinking was significant only in small- and medium-sized cities in terms of suicidal ideation. Conclusion: Suicide prevention programs for adolescents should be implemented given the higher incidence of suicidal ideation among female adolescents, the greater influence of mental health-related variables in counties, and the influence of smoking in cities. There were differences in the prevalence and risk factors of suicidal ideation by residential areas.

Abstract	The development of short-wave infrared photodetectors based on various two-dimensional (2D) materials has recently attracted attention because of the ability of these devices to operate at room temperature. Although van der Waals heterostructures of 2D materials with type-II band alignment have significant potential for use in short-wave infrared photodetectors, there is a need to develop photodetectors with high photoresponsivity. In this study, we investigated the photogating of graphene using a monolayer-MoS2/monolayer-MoTe2 van der Waals heterostructure. By stacking MoS2/MoTe2 on graphene, we fabricated a broadband photodetector that exhibited a high photoresponsivity (>100 mA/W) and a low dark current (60 nA) over a wide wavelength range (488−1550 nm).

Abstract	With the development of artificial intelligence technology, systems that can actively adapt to their surroundings and cooperate with other systems have become increasingly important. One of the most important factors to consider during the process of cooperation among systems is trust. Trust is a social concept that assumes that cooperation with an object will produce positive results in the direction we intend. Our objectives are to propose a method for defining trust during the requirements engineering phase in the process of developing self-adaptive systems and to define the trust evidence models required to evaluate the defined trust at runtime. To achieve this objective, we propose in this study a provenance-based trust-aware requirement engineering framework for self-adaptive systems. The framework helps system engineers derive the user's requirements as a trust-aware goal model through analysis of the trust concept in the requirements engineering process. We also propose a provenance-based trust evidence model to evaluate trust and provide a method for defining this model for the target domain. Through the proposed framework, a system engineer can treat trust as a factor emerging from the requirements engineering phase for the self-adaptive system and understand the factors affecting trust using the standardized format.

Abstract	The coronavirus disease 2019 (COVID-19) pandemic has induced many lifestyle changes, with reductions in healthy activities, including walking. The aim of this cross-sectional study was to identify strategies to maintain good health during a pandemic. Demographics, walking habits, health behaviors, health status, recognition of social capital, and changes in walking practice of 800 residents were evaluated using a structured questionnaire. Among the participants, 73.9%, 15.8%, and 10.4% reported no change, a decrease, and an increase in walking practice, respectively. Individuals in their 50 s and 60 s showed 6.388- and 5.054-times greater increases in walking, respectively, than did those aged 19-29 years. Walking increased more among high-income people than among low-income people. Additionally, walking practice increased in people participating in social gatherings, those with pets that needed walks, those with a COVID-19 history, those who considered walking as both a habitual and leisure activity, those with nearly no stress, and those satisfied with their safety, the natural environment, and public transportation; other health behaviors or conditions were not related to an increase in walking practice. To maintain good health during a pandemic, walking practice should be promoted in people in their 20 s and low-income groups. Moreover, people should be encouraged to attend meetings, including online interaction, and safe walking routes should be created within the community. Walking should be encouraged as a method of relieving stress, and the benefits of walking for recovery after an infectious disease should be emphasized. Furthermore, the direct effects of walking should be studied.

Abstract	Background: As many older people spend their time in residential care facilities, the demand for person-centered care (PCC), which affects their quality of life, is increasing. Many residential care facility residents have cognitive problems, such as dementia and strokes. Providing quality care upholds their rights as human beings. Currently, the PCC tools used in South Korea are only translations of foreign tools into Korean, so it is necessary to develop tools for older adult care facilities that reflect the reality of Korean care facilities for older adults. This study aims to develop a tool for measuring PCC in residential care facilities for older people from the perspectives of care givers. Methods: The draft of 34 questions was developed through literature reviews, interviews with LTC practitioners and researchers. This developed questionnaire was then administered to 402 direct caregivers working in the residential care facilities because many of the residents had cognitive problems. By measuring the interrater reliability, the items with high levels of agreement were selected and the validity of the construct was checked through factor analysis. To determine whether the domains adequately measured each concept, we calculated correlation coefficients and Cronbach's α. Results: Four domains and 32 items concerning service conditions, resident's right to self-determination, a comfortable living environment for all residents, and resident and staff satisfaction are derived, thus explaining 24.7%, 23.6%, 14.6%, and 8.00% of the total variance, respectively. Cronbach's alphas for each domain are 0.965, 0.948, 0.652, and 0.525, respectively, thus demonstrating internal consistency. The inter-rater agreement is high (66.7%~100.0%). The correlation between service conditions and resident's right to self-determination (r = 0.643, p < 0.001), a comfortable living environment for all residents, resident and staff satisfaction (r = 0.674, p < 0.001), and resident's right to self-determination and comfortable living environment (r = 0.695, p < 0.001) is strong. Conclusions: It is important that caregivers recognize PCC and provide services. When evaluating the residential care services, measuring the degree of PCC should be made compulsory. If the facility becomes more person-centered, it will be possible to promote quality of life for older people. Trial registration: Not applicable.

Abstract	Deep learning-based super-resolution ultrasound (DL-SRU) framework has been successful in improving spatial resolution and measuring the velocity field information of a blood flows by localizing and tracking speckle signals of red blood cells (RBCs) without using any contrast agents. However, DL-SRU can localize only a small part of the speckle signals of blood flow owing to ambiguity problems encountered in the classification of blood flow signals from ultrasound B-mode images and the building up of suitable datasets required for training artificial neural networks, as well as the structural limitations of the neural network itself. An artificial intelligence-based speckle featurization and localization (AI-SFL) framework is proposed in this study. It includes a machine learning-based algorithm for classifying blood flow signals from ultrasound B-mode images, dimensionality reduction for featurizing speckle patterns of the classified blood flow signals by approximating them with quantitative values. A novel and robust neural network (ResSU-net) is trained using the online data generation (ODG) method and the extracted speckle features. The super-resolution performance of the proposed AI-SFL and ODG method is evaluated and compared with the results of previous U-net and conventional data augmentation methods under in silico conditions. The predicted locations of RBCs by the AI-SFL and DL-SRU for speckle patterns of blood flow are applied to a PTV algorithm to measure quantitative velocity fields of the flow. Finally, the feasibility of the proposed AI-SFL framework for measuring real blood flows is verified under in vivo conditions.
