The purpose of this study is to empirically verify how UI usability of mobile healthcare applications affects the perception of technostress and continuous use of elderly users. Through this, the effect of UI usability of mobile healthcare applications on technostress and continuous use intention was demonstrated for 199 people aged over 60. As a result, all four sub-factors of UI usability had a significant effect on technostress, and the magnitude of the influence was found to be in the order of content, process, design, and system. On the other hand, it was found that technostress had a significant effect on the intention of continued use. Through the above results, a UI design strategy that can lead to continuous use by relieving the technostress experienced by the elderly was suggested. This provides academic and practical implications for the future development and service direction of mobile healthcare applications for the elderly.

The Philippines is still in a tight battle with the coronavirus disease 2019 pandemic since many cases are detected daily. With the continuous spread of another disease worldwide-monkeypox, many Filipinos are alarmed if the country's healthcare system is prepared enough, especially with the detection of its first case. Learning from the unfortunate experiences of the country during the current pandemic is essential in facing another health crisis. With this, recommendations for a robust healthcare system are proposed centered on: a massive digital information campaign about the disease; training healthcare workers to raise awareness about the virus and its transmission, management, and treatment; an intensified surveillance and detection procedure to monitor cases and execute contact tracing properly; and a persistent procurement of vaccines and drugs for treatment, with a well-designed vaccination program.

Increasing of number of people who suffered from long term chronic diseases which required frequent daily health monitoring and body check up in conjunction with the trendy uses of mobile phones and Personal Digital Assistants (PDAs) in various ubiquitous computing had make portable healthcare system a well known application today. A mobile phone based portable healthcare monitoring system with multiple vital signals monitoring ability at real time in WSN and CDMA network is developed. This system carries out real time monitoring and local data analysis process in the mobile phone. Any detection of abnormal health condition and diagnosis at earlier stage will reduce the risk of patient's life. As an extension to the existing model, a pre-diagnosis management system (PDMS) is designed to minimize the time consuming in pre-diagnosis process in the hospital or healthcare center. An alert is sent to the web server at the healthcare center when the patient detects his health is at critical state where the immediate diagnosis is needed. Preparation of diagnosis equipments and arrangement of doctor and nurses at the hospital side can be done earlier before the arrival of patient at the hospital with the help of PDMS. An efficient pre-diagnosis management increases the chances of diseases recovery rate as well.

Designing environments for the elderly includes studying changes in the elderly themselves, changes in their environment, and changes in the intercommunication between the elderly and their environment. The purpose of this study is to provide guidelines for a ubiquitous environment in which seniors can "age in place," using an environment-behavioral approach. 305 subjects aged 45 to 78 take part in the survey research. Temporal sequence (age groups) and behavior (daily activities) are considered as the significant variables to design digital services for the elderly in the perspective of an environment-behavioral approach. Several conclusions can be made. (1) The characteristics of subjects in the over-65 age group shows that they manage an independent lifestyle even if they realize some body functions deteriorate as they age. (2) Over-65 age group is more engaged in healthcare and pastime activities. The male subjects of it are most inactive. (3) The IDA (importance of daily activities) and FDA (frequency of daily activities) are classified by five to six factors in each group. The IDA and FDA of the group aged over 65 differ from other age groups. (4) Five affordance dimensions of digital services for the elderly are proposed: Healthcare, Domesticity, Mobility & Security, Network, and Recreation & Pastime. These affordance dimensions will help research groups or companies design ubiquitous environments to enhance the quality of life of seniors.

Digital therapeutics based on software, such as artificial intelligence, virtual reality, games, and smartphone applications, are in the spotlight as new therapeutic alternatives in child and adolescent psychiatry. It draws attention to overcoming conventional therapeutics' limitations, such as toxicity, cost, and accessibility, and encourages patients to participate in the treatment attractively. The growth potential of the digital therapeutics market for psychiatric disorders in children and adolescents in Korea and abroad has been highlighted. Clinical studies and Food and Drug Administration approvals for digital therapeutics have increased, and cases approved by the Ministry of Food and Drug Safety have emerged in Korea. As seen above, digital transformation in child and adolescent psychiatry will change treatment paradigms significantly. Therefore, as this new field has just begun to emerge, it is necessary to verify the effectiveness and scope of the application of digital therapeutics and consider preparing a compensation system and institutional arrangements. Accordingly, this study analyzed the development trends and application status of digital therapeutics in children and adolescents and presented limitations and development directions from the perspective of application in healthcare. Further, the study is expected to identify the utility and limitations of digital therapeutics for children and adolescents and establish effective application measures.

Objective: To compare the accuracy for detecting breast cancer in the diagnostic setting between the use of digital breast tomosynthesis (DBT), defined as DBT alone or combined DBT and digital mammography (DM), and the use of DM alone through a systematic review and meta-analysis. Materials and Methods: Ovid-MEDLINE, Ovid-Embase, Cochrane Library and five Korean local databases were searched for articles published until March 25, 2020. We selected studies that reported diagnostic accuracy in women who were recalled after screening or symptomatic. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. A bivariate random effects model was used to estimate pooled sensitivity and specificity. We compared the diagnostic accuracy between DBT and DM alone using meta-regression and subgroup analyses by modality of intervention, country, existence of calcifications, breast density, Breast Imaging Reporting and Data System category threshold, study design, protocol for participant sampling, sample size, reason for diagnostic examination, and number of readers who interpreted the studies. Results: Twenty studies (n = 44513) that compared DBT and DM alone were included. The pooled sensitivity and specificity were 0.90 (95% confidence interval [CI] 0.86-0.93) and 0.90 (95% CI 0.84-0.94), respectively, for DBT, which were higher than 0.76 (95% CI 0.68-0.83) and 0.83 (95% CI 0.73-0.89), respectively, for DM alone (p < 0.001). The area under the summary receiver operating characteristics curve was 0.95 (95% CI 0.93-0.97) for DBT and 0.86 (95% CI 0.82-0.88) for DM alone. The higher sensitivity and specificity of DBT than DM alone were consistently noted in most subgroup and meta-regression analyses. Conclusion: Use of DBT was more accurate than DM alone for the diagnosis of breast cancer. Women with clinical symptoms or abnormal screening findings could be more effectively evaluated for breast cancer using DBT, which has a superior diagnostic performance compared to DM alone.

For home healthcare, the unconstrained measurement of physiological signal is highly required to avoid the inconvenience of users. The recording and analysis of the fundamental parameters during sleep like respiration and heart beat provide valuable information on his/her healthcare. Using the air mattress sensor system, the respiration and heart beat movements can be measured without any harness or sensor on the subject's body. The differential measurement technique between two air cells is adopted to enhance the sensitivity. The balancing tube between two air cells is used to increase the robustness against postural changes during the measurement period. The meaningful frequency range could be selected by the pneumatic filter with balancing tube. ECG (Electrocardiography) and respiration sensor (plethysmography) were measured for comparison with the signal from air mattress. To extract the heart beat information from air pressure sensor, digital signal processing technique was used. The accuracy for breathing interval and heart beat monitoring was acceptable. It shows the potentials of air mattress sensor system to be the unconstrained home sleep monitoring system.
