Breast cancer is the most prevalent cancer among women worldwide, requiring early and accurate diagnosis to reduce mortality. This study proposes a hybrid classification pipeline that integrates Hybrid Statistical Feature Selection (HSFS) with unsupervised LSTM-guided feature extraction for breast cancer detection using the Wisconsin Diagnostic Breast Cancer (WDBC) dataset. Initially, 20 features were selected using HSFS based on Mutual Information, Chi-square, and Pearson Correlation. To address class imbalance, the training set was balanced using the Synthetic Minority Over-sampling Technique (SMOTE). Subsequently, an LSTM encoder extracted non-linear latent features from the selected features. A fusion strategy was applied by concatenating the statistical and latent features, followed by re-selection of the top 30 features. The final classification was performed using a Support Vector Machine (SVM) with RBF kernel and evaluated using 5-fold cross-validation and a held-out test set. Experimental results showed that the proposed method achieved an average training accuracy of 98.13%, F1-score of 98.13%, and AUC-ROC of 99.55%. On the held-out test set, the model reached an accuracy of 99.30%, precision of 100%, and F1-score of 99.05%, with an AUC-ROC of 0.9973. The proposed pipeline demonstrates improved generalization and interpretability compared to existing methods such as LightGBM-PSO, DHH-GRU, and ensemble deep networks. These results highlight the effectiveness of combining statistical selection and LSTM-based latent feature encoding in a balanced classification framework.

Christian education has played a significant role in shaping individual character, thought, and morality across the globe. One of the most influential figures in this field is Ignatius Loyola (1491-1556), founder of the Society of Jesus (Jesuits). Loyola’s educational philosophy, rooted in Catholic spirituality, emphasizes discipline, character formation, and the integration of faith and intellect. The purpose of this study is to explore the theological foundations of Christian education according to Ignatius Loyola, outline the core principles of his educational thought, and examine its relevance to contemporary Christian education. Data were collected through a literature review of books and scholarly articles. Loyola’s approach, known as Ignatian education, focuses on holistic development-spiritual, intellectual, and social-embodied in the principle of "cura personalis" or care for the whole person. His model has profoundly influenced Catholic educational institutions worldwide. The findings highlight that Ignatian pedagogy not only nurtures academic excellence but also fosters a spirit of service and commitment to God. This research provides insights for educators and institutions aiming to implement Christian values in modern educational settings.

The rehabilitation program through physiotherapy has proven effective in accelerating the recovery of knee injuries in soccer athletes by employing a structured approach that includes pain reduction, mobility enhancement, and muscle strengthening. Case studies and research indicate that a combination of interventions such as cryotherapy, Transcutaneous Electrical Nerve Stimulation (TENS), range of motion (ROM) exercises, and muscle strengthening leads to significant improvements within 3-6 weeks. The primary methods utilized include physical therapy to reduce edema and pain through modalities like cold compresses and electrical stimulation, progressive exercises focusing on flexibility, balance, and strength of the quadriceps-hamstring muscles, as well as a phased rehabilitation approach (acute, restoration, strengthening) tailored to the patient's clinical condition. Research involving 25 patients post-ACL surgery showed an increase in passive flexion ROM of 31.07% and a decrease in swelling by 3.33% after therapy sessions. For soccer athletes, these interventions facilitate a return to optimal movement function within a short timeframe through controlled sport-specific exercises. The study concludes that a comprehensive physiotherapy program significantly accelerates functional recovery and reduces the risk of long-term complications.
