"Tujuan: Untuk mengetahui prevalensi miopia pada penjahit dan faktor-faktor risiko lain yang mempengaruhinya serta hubungan antara kerja jarak dekat dengan miopia. Metoda: Desain penelitian adalah cross sectional dengan subyek penelitian terdiri dari 310 penjahit wanita di Departemen Stitching Atletik 11 Pabrik Sepatu `X'. Pengumpulan data dilaksanakan pada bulan April sampai dengan Mei 2004 dengan pengukuran jarak kerja secara langsung pada subyek, pengukuran iluminasi di tempat kerja dan wawancara dengan kuesioner. Sedangkan status refraksi berdasarkan basil pemeriksaan berkala 1 tahun sebelumnya. Hasil yang diperoleh diolah menggunakan komprrter dengan program SPSS 11.0. Hasil: Terdapat 39 orang (12,6%) penderita miopia pada penjahit wanita di Departemen .S'titching Atletik 11 Pabrik Sepatu terdiri dari 36 orang (92,3%) miopia ringan dan 3 orang (7,9%) miopia sedang. Dengan regresi logistik ditemukan hubungan yang bermakna antara kerja jarak dekat dengan miopia (OR = 1,206; p = 0,001). Tidak ditemukan hubungan yang bermakna antara faktor-faktor lain dengan miopia. Kesimpulan: Ditemukan hubungan yang bermakna secara statistik antara kerja jarak dekat dengan miopia pada penjahit wanita di Departemen Stitching Atletik I I Pabrik Sepatu X.

Purpose: To investigate myopia prevalence among stitchers, and other influential factors and the relationship between neanvork and myopia.

Methods: A cross sectional study was performed among 310 female shoe stitchers in Athletic Shoes Stitching 11 Department of `X' Shoe Factory. Data was collected from April until May 2004, including measurement of work distance and ilumination and interviewing with questionnaire. Whereas subject's refraction status based on the medical check-up record of the one year before. The collected data was processed by SPSS 11.0 computer programme.

Results: There were 39 (12,6%) miopic female shoe stitchers, consisted of 36 (92,3%) mild myopia and 3 (7,9%) moderate myopia. Logistic regression model revealed the significant relationship between nearwork and myopia (OR = 1.206; p - 0,001). No relationship was found between other factors and myopia.

Conclusion: There is statistically significant relationship between neanvork and myopia among female shoe stitchers in Athletic Shoes Stitching 11 Department of X Shoe Factory."

"This book continues first one of the same authors Adaptive Image Processing Algorithms for Printing and presents methods and software solutions for copying and scanning various types of documents by conventional office equipment, offering techniques for correction of distortions and enhancement of scanned documents; techniques for automatic cropping and de-skew; approaches for segmentation of text and picture regions; documents classifiers; approach for vectorization of symbols by approximation of their contour by curves; methods for optimal compression of scanned documents, algorithm for stitching parts of large originals; copy-protection methods by microprinting and embedding of hidden information to hardcopy; algorithmic approach for toner saving. In addition, method for integral printing is considered. Described techniques operate in automatic mode thanks to machine learning or ingenious heuristics. Most the techniques presented have a low computational complexity and memory consumption due to they were designed for firmware of embedded systems or software drivers. The book reflects the authors practical experience in algorithm development for industrial R&D. "

"Sepak bola merupakan olahraga yang membutuhkan analisis performa untuk meningkatkan strategi permainan dan mencegah cedera pada pemain. Penelitian ini mengembangkan sistem kamera semi-portabel untuk analisis performa sepak bola secara waktu nyata, menggunakan platform NVIDIA Jetson Nano. Sistem ini mengintegrasikan algoritma stitching panorama, deteksi objek berbasis YOLO, dan dynamic zoom untuk menghasilkan analisis akurat terhadap pergerakan pemain dan bola. Hasil eksperimen menunjukkan bahwa algoritma yang dikembangkan mencapai Mean IoU hingga 0,97, dengan presisi tinggi dan recall yang baik. Sistem ini juga dapat menghasilkan tampilan lapangan panorama yang konsisten serta fokus dinamis pada area permainan yang relevan. Namun, beberapa tantangan seperti keterbatasan komputasi, pelambatan termal dan distorsi kamera masih membatasi performa waktu nyata. Dengan peningkatan perangkat keras dan optimasi algoritma, sistem ini berpotensi untuk menjadi alat analitik yang lebih andal, terjangkau, dan dapat diakses oleh tim amatir maupun semi-profesional.

Soccer is a sport that requires performance analysis to enhance game strategies and prevent player injuries. This research developed a semi-portable camera system for real-time soccer performance analysis using the NVIDIA Jetson Nano platform. The system integrates panoramic stitching algorithms, YOLO-based object detection, and dynamic zoom to provide accurate analysis of player and ball movements. Experimental results demonstrate that the developed algorithms achieved a Mean IoU of up to 0.97, with high precision and recall. The system also successfully produced consistent panoramic field views and dynamic focus on relevant gameplay areas. However, challenges such as computational limitations, thermal throttling, and camera distortion currently limit real-time performance. With hardware upgrades and algorithm optimizations, the system has the potential to become a more reliable, affordable, and accessible analytical tool for amateur and semi-professional teams. "
