Abstract

Carpal Tunnel Syndrome (CTS) is an occupational disease caused by disruption of the hand position which is constantly and is often associated with activities that use the hands for a long time can affect nerves, blood supply to the hands and wrists. This study aims to determine the relationship between workload, repetitive wrist movements and work time with carpal tunnel syndrome in cantel eyelash workers. Type of research is observational with cross-sectional approach. The sample in study were 50 eyelash workers who were part of the cantel. The results of this study are there is no relationship between workload and the incidence of CTS (p=1.000), there is a relationship between repetitive wrist movements with the incidence of CTS (p=0.031) and There is a relationship between years of service and the incidence of CTS (p=0.007). The conclusion is repetitive wrist movements performed by workers during years of work are a risk factor for carpal tunnel syndrome. So that to reduce this risk, it is necessary to stretch your hands before working, every two hours of work and finish working.

Abstract

Pulmonary Tuberculosis (TB) is an infectious disease caused by Mycobacterium Tuberculosis, this disease becomes a public health problem, especially if there is a break in treatment which has an impact on TB drug resistance. The purpose of this study is to see the correlation or relationship of determinant factors that influence the success of pulmonary tuberculosis treatment. The type of research is Observational Analytical with a Cross Sectional approach. Data collection uses questionnaires, observations and interviews. The population is 158 and the sample is 91 respondents with cluster sampling. The study was conducted in Parigi Moutong Regency during February-June 2025. Of the 91 respondents who were 94.5% compliant with taking medication, 75.8% had good Family Support, 75.8% had Drug Supervisor (PMO) Support and 83.5% had Health Worker Support, the results of the chi square test showed a relationship between medication adherence and the success of Pulmonary TB Treatment p = 0.000 <0.05, there was a relationship between family support and the success of Pulmonary TB Treatment p = 0.001 <0.05, there was a relationship between support (PMO) and the success of Pulmonary TB Treatment p = 0.001 <0.05 and there was a relationship between Health Worker support and the success of Pulmonary TB Treatment p = 0.000 <0.005. Conclusion There is a relationship between behavior (medication adherence, family support, PMO support and health worker support) and the success of pulmonary TB treatment.

Abstract

Deteksi epilepsi berbasis electroencephalogram (EEG) menghadapi tantangan berupa ketidakseimbangan kelas, data leakage, dan variasi sinyal antarpasien. Penelitian ini mengusulkan representasi distribusi energi EEG multikanal menggunakan Support Vector Machine (SVM) dengan kernel Radial Basis Function (RBF). Dataset CHB-MIT dipreproses dan disegmentasi menjadi window berdurasi 2 detik dengan overlap 25%. Setiap window direpresentasikan oleh 23 fitur energi domain waktu dan 23 fitur Power Spectral Density (PSD) metode Welch, sedangkan energy map berukuran 23 × 16 digunakan sebagai visualisasi distribusi energi kanal–waktu dan bukan sebagai masukan model. Evaluasi dilakukan menggunakan independent file-wise testing, grouped file-wise 5-fold cross-validation, dan patient-wise Leave-One-Subject-Out (LOSO). Untuk mencegah data leakage, pembagian data dilakukan pada tingkat file atau pasien sebelum segmentasi, sedangkan undersampling dan standardisasi hanya diterapkan pada data pelatihan. Hasil file-wise testing menunjukkan akurasi 93,247%, sensitivitas 98,387%, F1-score 42,958%, dan ROC-AUC 0,9880. Pada evaluasi LOSO, akurasi, sensitivitas, dan F1-score menurun menjadi 78,071%, 51,909%, dan 20,550%, yang menunjukkan adanya inter-subject variability. Uji Mann–Whitney menunjukkan perbedaan distribusi energi yang signifikan antara kelas seizure dan non-seizure (p = 2,1804 × 10⁻¹⁴⁰). Metode ini efektif untuk deteksi antarfile pada pasien yang sama, namun masih memerlukan validasi lintas pasien dan dataset eksternal untuk meningkatkan kemampuan generalisasi. Kata kunci: CHB-MIT, deteksi epilepsi, distribusi energi EEG, patient-wise LOSO, SVM.

Abstract

Infectious disease transmission in healthcare settings remains a critical challenge that threatens both patient and healthcare worker safety. Strengthening nurses’ knowledge and attitudes through structured training programs is essential to improve infection prevention practices and compliance with personal protective equipment (PPE) use. This study aimed to analyze the effectiveness of classical training methods and classical training combined with educational booklets in improving nurses’ knowledge and attitudes regarding infectious disease transmission and PPE use. A quasi-experimental design with a pretest–posttest comparison group approach was conducted among 72 nurses, divided equally into two intervention groups (n = 36 each). Data were analyzed using Wilcoxon and Mann-Whitney. The results showed that in the classical training group, the mean knowledge score increased from 23.17 ± 1.134 to 23.89 ± 0.319 (p = 0.001), and the mean attitude score increased from 66.83 ± 4.365 to 69.50 ± 4.226 (p = 0.005). In the classical training combined with booklet group, the mean knowledge score increased from 23.33 ± 0.894 to 23.86 ± 0.424 (p = 0.006), while the mean attitude score increased from 66.81 ± 3.463 to 68.08 ± 4.607 (p = 0.026). However, there were no statistically significant differences in knowledge improvement (p = 0.496) or attitude improvement (p = 0.263) between the two groups. In conclusion, both training methods were effective in significantly improving nurses’ knowledge and attitudes regarding infectious disease transmission and PPE use. Nevertheless, no significant difference in effectiveness was found between the classical training method and the classical training combined with educational booklets. Keyword: Knowledge, attitude, training methods, infectious diseases, personal protective equipment
