As digital technology becomes more prevalent in today’s business environment and interest in digital trust rises, restaurants need to identify whether and how their mobile apps enhance the customer experience, and what features of the apps can strengthen customers’ attachment to them. However, few studies have examined the role of restaurant mobile apps as a catalyst for building customer loyalty. Considering restaurant mobile apps as a means to build a trustworthy relationship between customers and restaurants, this study develops and validates a research framework to measure digital trust between restaurants and customers through restaurant mobile apps. Specifically, due to the lack of measurement constructs for digital trust, a reliable and valid set of measurements that can explain digital trust in relation to restaurant mobile apps is developed and the effects of mobile apps’ digital trust on customers’ trust in a restaurant brand, overall experience, and their continued use intention are assessed.

Background: Swallowing disorder is a common disease that can cause various complications such as malnutrition, dehydration, aspiration pneumonia, and poor quality of life, and can affect people of all ages, from infants to the elderly. Swallowing disorder rehabilitation is a complex process involving various skills such as exercise, diet modification, and posture adjustment. This study implements a rehab program for swallowing disorders using the Kinesio Tapping technique. Design: Prospective pilot case study. Objectives: To improve laryngeal detachment by providing external support to the muscles involved in swallowing using kinesio taping for conventional complex swallowing disorder rehabilitation. Methods: The study included 16 participants who were diagnosed with swallowing difficulties after a stroke and admitted to a rehabilitation ward in Ulsan. The average age of the participants, consisting of 9 males and 7 females, was 69.0 years (SD=1.23) and 64.0 years (SD=1.45), respectively. The stroke types were hemorrhagic and infarction, with onset periods ranging from 6 to 12 months (SD=1.11) in all participants. Each participant received a video fluoroscopy study (VFSS) for six months using the taping method developed by the research team. Kinesio taping techniques were developed by two professional physical therapists and one occupational therapist based on anatomical movements. Results: Significant differences were observed in self-training on the bed after the rehabilitation program compared to the initial period Kinesio taping can help improve laryngeal dislocation and reduce the risk of aspiration by providing external support to the muscles involved in swallowing. However, the effectiveness and optimal application techniques of kinesio taping in the rehabilitation of swallowing disorders are not yet clear. Conclusion: The results of this study could lead to the development of a new treatment protocol that incorporates kinesio taping as a standard therapy for the rehabilitation of swallowing disorders in bedridden patients.

The prolonged and heavy East Asian summer precipitation in 2020 may have been caused by an enhanced Madden-Julian Oscillation (MJO), which requires evaluation using forecast models. We examined the performance of GloSea6, an operational forecast model, in predicting the East Asian summer precipitation during July 2020, and investigated the role of MJO in the extreme rainfall event. Two experiments, CON and EXP, were conducted using different convection schemes, 6A and 5A, respectively to simulate various aspects of MJO. The EXP runs yielded stronger forecasts of East Asian precipitation for July 2020 than the CON runs, probably due to the prominent MJO realization in the former experiment. The stronger MJO created stronger moist southerly winds associated with the western North Pacific subtropical high, which led to increased precipitation. The strengthening of the MJO was found to improve the prediction accuracy of East Asian summer precipitation. However, it is important to note that this study does not discuss the impact of changes in the convection scheme on the modulation of MJO. Further research is needed to understand other factors that could strengthen the MJO and improve the forecast.

The rapid detection of bacteria in the oral cavity, its species identification, and bacterial count determination are important to diagnose oral diseases caused by pathogenic bacteria. The existing clinical microbial diagnosis methods are time-consuming as they involve observing patients’ samples under a microscope or culturing and confirming bacteria using polymerase chain reaction (PCR) kits, making the process complex. Therefore, it is required to analyze the development status of substances and systems that can rapidly detect and analyze pathogenic microorganisms in the oral cavity. With research advancements, a close relationship between oral and systemic diseases has been identified, making it crucial to identify the changes in the oral cavity bacterial composition. Additionally, an early and accurate diagnosis is essential for better prognosis in periodontal disease. However, most periodontal diseasecausing pathogens are anaerobic bacteria, which are difficult to identify using conventional bacterial culture methods. Further, the existing PCR method takes a long time to detect and involves complicated stages. Therefore, to address these challenges, the concept of point-of-care (PoC) has emerged, leading to the study and implementation of various chair-side test methods. This study aims to investigate the different PoC diagnostic methods introduced thus far for identifying pathogenic microorganisms in the oral cavity. These are classified into three categories: 1) microbiological tests, 2) microchemical tests, and 3) genetic tests. The microbiological tests are used to determine the presence or absence of representative causative bacteria of periodontal diseases, such as A. actinomycetemcomitans , P. gingivalis , P. intermedia , and T. denticola . However, the quantitative analysis remains impossible, and detecting pathogens other than the specific ones is challenging. The microchemical tests determine the activity of inflammation or disease by measuring the levels of biomarkers present in the oral cavity. Although this diagnostic method is based on increase in the specific biomarkers proportional to inflammation or disease progression in the oral cavity, its commercialization is limited due to low sensitivity and specificity. The genetic tests are based on the concept that differences in disease vulnerability and treatment response are caused by the patient’s DNA predisposition. Specifically, the IL-1 gene is used in such tests. PoC diagnostic methods developed to date serve as supplementary diagnostic methods and tools for patient education, in addition to existing diagnostic methods, although they have limitations in diagnosing oral diseases alone. Research on various PoC test methods that can analyze and manage the oral cavity bacterial composition is expected to become more active, aligning with the shift from treatmentoriented to prevention-oriented approaches in healthcare.

Biomass-derived porous carbon is an excellent scientific and technologically interesting material for supercapacitor applications. In this study, we developed biomass-derived nitrogen-doped porous carbon nanosheets (BDPCNS) from cedar cone biomass using a simple KOH activation and pyrolysis method. The BDPCNS was effectively modified at different temperatures of 600 °C, 700 °C, and 800 ℃ under similar conditions. The as-prepared BDPCNS-700 electrode exhibited a high BET surface area of 2883 m2 g− 1 and a total pore volume of 1.26 cm3 g− 1. Additionally, BDPCNS-700 had the highest electrical conductivity (11.03 cm− 1) and highest N-doped content among the different electrode materials. The BDPCNS-700 electrode attained a specific capacitance of 290 F g− 1 at a current density of 1 A g− 1 in a 3 M KOH electrolyte and an excellent longterm electrochemical cycling stability of 93.4% over 1000 cycles. Moreover, the BDPCNS-700 electrode had an excellent energy density (40.27 Wh kg− 1) vs power density (208.19 W kg− 1). These findings indicate that BDPCNS with large surface areas are promising electrode materials for supercapacitors and energy storage systems.
