Published: June 2024

: Total knee arthroplasty (TKA) has been particularly challenging in patients who present with valgus knee deformity, which constitutes about 10% of cases. The current study seeks to review the functional and radiological outcomes of patients treated with TKA.: A total of 40 knees in 30 patients with valgus deformity were the subjects of the current study. Most of them (38 knees) had a medial parapatellar approach, while two underwent an anterolateral approach. We assessed the outcome with the Knee Society score (KSS), the Visual Analogue Scale (VAS) for pain, and the radiological alignment through the Hip Knee Ankle Axis (HKA). The measurements are done in 6-week, 3-month, 6-month, and months of an immediate post-operative.: There is a very clear improvement in all these measures. The KSS knee scores improved from 54 preoperatively to 92 in one year (p &#60; 0.01), and the KSS functional scores also improved significantly from 52 to 87 (p &#60; 0.01). The pain intensity scores clearly decreased from the preoperative average of 5.30 to 0 postoperatively (p &#60; 0.001). Radiologically, there was improved alignment, with HKA angles decreasing from 9.12 preoperatively to 6.25 postoperatively.: TKA significantly improved the functional outcome and reduced pain among patients presenting with a valgus knee deformity. This resulted from a clear improvement seen in the KSS, VAS, and HKA measures. The study continues to show the effectiveness of TKA in improving clinical outcomes among these difficult groups of patients.

Published: June 2024

La geopolítica en el ámbito espacial contemporáneo se caracteriza por una compleja red de actores con intereses diversos y capacidades variables. A diferencia de la carrera espacial del siglo XX, actualmente se observa un escenario multipolar con la participación de Estados Unidos (EE. UU.), Europa, Rusia, China, India, Japón y otros actores. Sin embargo, el Derecho Internacional Espacial históricamente ha tenido características de ser reactivo a los cambios, y no proactivo en su regulación. De tal manera, este artículo analiza cuáles son las actuales tendencias en materia de geopolítica espacial y sus implicancias en el Derecho.
Comparison and Analysis of CNN Models to Improve a Facial Emotion Classification Accuracy for Koreans and East Asians

Published: June 2024

Facial emotion recognition is one of the popular tasks in computer vision. Face recognition techniques based on deep learning can provide the best face recognition performance, but using these techniques requires a lot of labeled face data. Available large-scale facial datasets are predominantly Western and contain very few Asians. We found that models trained using these datasets were less accurate at identifying Asians than Westerners. Therefore, to increase the accuracy of Asians' facial identification, we compared and analyzed various CNN models that had been previously studied. We also added Asian faces and face data in realistic situations to the existing dataset and compared the results. As a result of model comparison, VGG16 and Xception models showed high prediction rates for facial emotion recognition in this study. and the more diverse the dataset, the higher the prediction rate. The prediction rate of the East Asian dataset for the model trained on FER2013 was relatively low. However, for data learned with KFE, the model prediction of FER2013 was predicted to be relatively high. However, because the number of East Asian datasets is small, caution is needed in interpretation. Through this study, it was confirmed that large CNN models can be used for facial emotion analysis, but that selection of an appropriate model is essential. In addition, it was confirmed once again that a variety of datasets and the prediction rate increase as a large amount of data is learned.

ABSTRACT
In this current investigation, the experimental performance of a solar still basin was significantly enhanced by incorporating snail shell biomaterials. The outcomes of the snail shell-augmented solar still basin (SSSS) are compared with those of a conventional solar still (CSS). The utilization of snail shells proved to facilitate the reduction of saline water and enhance its temperature, thereby improving the productivity of the SSSS. Cumulatively, the SSSS productivity was improved by 4.3% over CSS. Furthermore, the SSSS outperformed in energy and exergy efficiency of CSS by 4.5 and 3.5%, respectively. Economically, the cost per liter of distillate (CPL) for the CSS was 3.4% higher than SSSS. Moreover, the SSSS showed a shorter estimated payback period (PBP) of 141 days which was 6 days less than CSS. Considering the environmental impact, the observed CO2 emissions from the SSSS were approximately 14.6% higher than CSS over its 10-year lifespan. Notably, the SSSS exhibited a substantial increase in the estimated carbon credit earned (CCE) compared to the CSS. Ultimately, the research underscores the efficacy of incorporating snail shells into solar still basins as a commendable approach to organic waste management, offering economic benefits without compromising environmental considerations.

Published: June 2024

Background
Dermatology is an ideal specialty for artificial intelligence (AI)–driven image recognition to improve diagnostic accuracy and patient care. Lack of dermatologists in many parts of the world and the high frequency of cutaneous disorders and malignancies highlight the increasing need for AI-aided diagnosis. Although AI-based applications for the identification of dermatological conditions are widely available, research assessing their reliability and accuracy is lacking.

Objective
The aim of this study was to analyze the efficacy of the Aysa AI app as a preliminary diagnostic tool for various dermatological conditions in a semiurban town in India.

Methods
This observational cross-sectional study included patients over the age of 2 years who visited the dermatology clinic. Images of lesions from individuals with various skin disorders were uploaded to the app after obtaining informed consent. The app was used to make a patient profile, identify lesion morphology, plot the location on a human model, and answer questions regarding duration and symptoms. The app presented eight differential diagnoses, which were compared with the clinical diagnosis. The model’s performance was evaluated using sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and F1-score. Comparison of categorical variables was performed with the χ2 test and statistical significance was considered at P<.05.

Results
A total of 700 patients were part of the study. A wide variety of skin conditions were grouped into 12 categories. The AI model had a mean top-1 sensitivity of 71% (95% CI 61.5%-74.3%), top-3 sensitivity of 86.1% (95% CI 83.4%-88.6%), and all-8 sensitivity of 95.1% (95% CI 93.3%-96.6%). The top-1 sensitivities for diagnosis of skin infestations, disorders of keratinization, other inflammatory conditions, and bacterial infections were 85.7%, 85.7%, 82.7%, and 81.8%, respectively. In the case of photodermatoses and malignant tumors, the top-1 sensitivities were 33.3% and 10%, respectively. Each category had a strong correlation between the clinical diagnosis and the probable diagnoses (P<.001).

Conclusions
The Aysa app showed promising results in identifying most dermatoses.

Published: June 2024

Background
Psychological internet-based interventions have shown promise in preventing and treating perinatal depression, but their effectiveness can be hindered by low user engagement. This challenge often arises from a misalignment between technology attributes, user needs, and context. A user-centered, iterative approach involving all stakeholders is recommended.

Objective
In this paper, we aimed to develop a user-friendly psychological internet-based intervention aimed at addressing the symptoms of perinatal depression through an iterative, user-centered approach.

Methods
The development process followed the Center for eHealth Research and Disease Management Roadmap phases of contextual inquiry, value specification, and design. It involved a comprehensive literature review, 2 surveys, 10 focus groups, 5 usability interviews, and 1 technical pilot.

Results
The contextual inquiry revealed a demand for accessible interventions for perinatal mental health, with internet-based solutions seen as viable options. Insights from the literature influenced intervention content and features. Stakeholders’ openness to the intervention became evident during this phase, along with the integration of the first set of values. Initially, we assessed the broader perinatal context to identify the optimal period for the intervention. On the basis of the findings and practical considerations, we decided to specifically target postpartum depression symptoms. The value specification phase further defined the central values and translated them into requirements. In the design phase, feedback was obtained on the user experience of an early digital prototype and on the prototype’s final version. The resulting intervention, named Mamá, te entiendo (“Mom, I get you”), is a guided web app based on cognitive behavioral therapy principles, integrating elements from attachment and mentalization theories. It aims to reduce depressive symptoms in women during the first months postpartum and consists of 6 core sequential modules, along with 3 additional modules, including 5 case examples illustrating depressive symptoms and therapeutic techniques. The intervention provides homework exercises and offers users the opportunity to receive feedback from an e-coach through the web app.

Conclusions
This study emphasizes the importance of a user-centered and iterative development process for psychological internet-based interventions. This process helps clarify user needs and provides valuable feedback on service design and quality, ultimately having the potential to enhance the utility and, presumably, the effectiveness of the intervention. The Discussion section shares valuable insights from the project, such as the value of the requirement sessions.
