Spastic Lower Paraparesis Due To Multiple Ossification Of The Ligamentum Flavum Of Fusion And Tuberous Type In The Thoracolumbar Region In A 42-Year-Old Woman
No full textOssification of the ligamentum flavum (OLF) is characterized by the replacement of ligamentum flavum tissue with mature laminar bone accompanied by hypertrophy. Although rare, its highest prevalence is reported among East Asian populations, predominantly affecting males under 50 years old, and most commonly found in the lower thoracic region. Clinically, OLF presents as a slowly progressive myelopathy, yet its precise pathogenesis remains unclear. Diagnostic imaging modalities include radiography, computed tomography (CT), and magnetic resonance imaging (MRI). This case report describes a 42-year-old female diagnosed with thoracolumbar OLF based on MRI examination. The patient presented with spastic paraparesis and hypoesthesia from both feet to dermatomes Th10–11 following a history of trauma. Lumbar radiography showed only lumbal spondylosis, while thoracolumbar MRI revealed nodular thickening of the ligamentum flavum from Th6–7 to Th12–L1, resulting in spinal canal stenosis and compression of the spinal cord. Additional degenerative findings included superior endplate degeneration of L4 and multiple intervertebral disc bulging. Neurological deficits indicated myelopathy and radiculopathy due to compression of the lateral corticospinal and spinothalamic tracts. The absence of spinal cord edema on MRI suggested a chronic onset. OLF frequently coexists with vertebral degenerative abnormalities, as observed in this patient. Based on the radiologic characteristics, the lesion represented several morphological types including extended, enlarged, fused, and tuberous forms. Laminectomy performed in this case resulted in gradual neurological recovery. In conclusion, OLF is a rare but important cause of progressive thoracic myelopathy that may lead to irreversible neurological impairment. MRI evaluation plays a crucial role in preoperative assessment of spinal canal stenosis and spinal cord compression

kekerasan pada nugget las, daerah Heat-Affected Zone (HAZ), dan material dasar,
serta analisis struktur makro dan mikro untuk mengamati morfologi nugget,
ukuran butir, dan fasa terbentuk. Hasil pengujian kekuatan geser menunjukkan
bahwa peningkatan kuat arus hingga titik optimum akan meningkatkan kekuatan
sambung karena pembentukan nugget yang lebih besar dan sempurna. Analisis
struktur makro dan mikro lebih lanjut mengkonfirmasikan perubahan ukuran
nugget dan morfologi butir akibat variasi arus, memberikan pemahaman
mendalam tentang korelasi antara parameter pengelasan dan kualitas sambung.
Dalam penelitian ini, spesimen las titik dibuat dengan variasi arus pengelasan
13000 A, 14000 A, dan 15000 A, sementara parameter lain seperti waktu
pengelasannya 2,5 detik, dan tekanan elektroda 4,6 kN. Penelitian ini diharapkan
dapat memberikan kontribusi dalam optimasi proses spot welding untuk aplikasi
industri.

variation on the mechanical and metallurgical properties of the joint in LOW
CARBON STEEL SPCC 590. The main objective of the study is to understand how
the variation of electric current affects the quality of the weld joint. Spot welding
is a widely used joining method in the automotive and manufacturing industries,
so a thorough understanding of its parameter optimization is crucial to ensure the
quality of the joint. The resistance spot welding method was chosen because of its
efficiency in joining sheet metal. In this study, tensile-shear tests were carried out
to evaluate the joint strength, Rockwell hardness tests to measure the hardness of
the weld nugget, Heat-Affected Zone (HAZ), and base material, as well as macro
and micro structural analysis to observe the nugget morphology, grain size, and
phase formed. The results of the shear strength test indicate that increasing the
current strength to the optimum point will increase the joint strength due to the
formation of larger and more perfect nuggets. Further macro and micro structural
analysis confirmed the changes in nugget size and grain morphology due to
current variation, providing a deeper understanding of the correlation between
welding parameters and joint quality. In this study, spot welding specimens were
made with variations of welding current of 13000 A, 14000 A, and 15000 A, while
other parameters such as welding time were 2.5 seconds, and electrode pressure
was 4.6 kN. This study is expected to contribute to the optimization of the spot
welding process for industrial applications.

Suffering in the Perspective of Being Religious
Full text linkHumans and suffering are inseparable because they complement each other throughout life. Basically, humans, as weak creatures, always seek religion as external guidance to support their lives. Therefore, we assert that religious premises serve as external power to help humans survive suffering by building an understanding of religion and suffering from the perspective of religious sociology and by offering an argument for how Job accepted suffering to show himself to be a religious man. In the last part of our paper, we will show that suffering forms a man as a religious man in the faith growth as part of the human life process
