Abstract

Stroke is a brain dysfunction that occurs suddenly as a result of local or overarching damage to the brain, lasts for at least 24 hours, and causes about 15 million deaths each year globally. Immediate medical treatment is essential to reduce the potential for further brain damage in stroke patients. Medical imaging, especially computed tomography (CT scan), plays a crucial role in the diagnosis of stroke. This study aims to develop and evaluate a deep learning architecture based on Convolutional Block Attention Module (CBAM) and ResNet18 for stroke classification in CT images. This model is designed through data preprocessing, training, and evaluation stages using a cross-validation approach. The results showed that the CBAM-ResNet18 integration resulted in a high accuracy of 95% in distinguishing stroke and non-stroke cases. The accuracy rate reached 96% for nonstroke identification (class 0) and 94% for stroke (class 1), with recall rates of 96% and 93%, respectively. Outstanding classification ability is demonstrated by an Area Under the Curve (AUC) value of 0.99. In comparison, the standard ResNet18 model shows significant fluctuations in validation loss and difficulty in generalization, with training accuracy only reaching 64-68%. On the other hand, CBAM-ResNet18 showed a significant performance improvement with a validation accuracy of 95%, a validation loss of 0.0888, and good generalization on new data. However, the limitations of the dataset and the interpretation of the results indicate the need for further validation to ensure the generalization of the model. These results show the great potential of the CBAM-ResNet18 architecture as an innovative tool in stroke diagnostic technology based on CT imaging analysis. This technology can support faster and more accurate clinical decision-making, as well as open up opportunities for further research related to the development of artificial intelligence-based systems in the medical field.

Abstract

Introduction: Patients undergoing surgery lasting more than two hours are at high risk of developing pressure injuries. To predict this risk, nurses can use the ELPO Scale, which assesses factors such as duration of surgery, body position, anesthesia, support, age, length of surgery, and comorbidities. This study aims to compare the results of the standard ELPO Scale with the modified ELPO Scale based on Myra Levine's Conservation Theory in detecting the risk of pressure injuries in patients undergoing surgery for more than two hours. Methods: This is a descriptive quantitative study with a retrospective case-control design using Chi-square analysis to assess the accuracy, sensitivity, and specificity of both scales. Results: The standard ELPO Scale did not show a significant relationship with the incidence of pressure ulcers. In contrast, the modified ELPO Scale had higher accuracy, sensitivity, and specificity in early detection. Conclusion: The modified ELPO Scale is more sensitive than the standard ELPO Scale in detecting the risk of pressure ulcers in surgical patients, with the factors of surgical position, age, mobilization, and skin moisture playing an important role in the occurrence of pressure ulcers.

Abstract

ABSTRACT Hospitals can be established by the Central Government, Regional Government, or the Community. Hospital management organized by the Government can apply the financial management pattern of BLU or BLUD. Hospital independence can be achieved through healthy business processes. The dual role of hospitals as public services and business entities. The commercial health sector is increasingly closely linked to the global health industry. Collaboration between BLU hospitals and private business entities is often manifested in KSO contracts. KSO contracts must contain legal principles (rechtbeginselen) which serve as basic norms and guidelines in the formation or creation of legal regulations. The principle of personality in KSO contracts is important to ensure the parties' performance is balanced. This study uses a normative or doctrinal legal research methodology by examining primary legal sources in the form of KSO contracts between BLU hospitals and private business entities, the Civil Code, and other material laws. A study was also conducted on secondary legal sources in the form of legal materials consisting of books or legal journals regarding legal principles, the views of legal doctrines, and the results of legal research. Keywords : Principle of Personality, Public Service Agency, Operational Cooperation Contract.
