Perkembangan teknologi GIS menyediakan konsep, alat, dan analisis yangmendukung kebutuhan teknik sipil dan lingkungan. Tulisan ini membahas secarasingkat konsep buffer analysis/multiple ring buffer analysis pada platform GIS dalamaplikasi teknik sipil dan lingkungan. Tulisan ini menjelaskan penelitian-penelitiansebelumnya yang menerapkan buffer analysis/multiple ring buffer analysis. Bufferanalysis/multiple ring buffer analysis digunakan untuk mengetahui area layanan (halte bus, shelter untuk bencana), yang umum digunakan dalam teknik sipil; dan untuk memahami area dampak (perletakan TPA, kebisingan), yang umum digunakan dalam bidang teknik sipil dan lingkungan. Tulisan ini menyebutkan keterbatasan buffer analysis/multiple ring buffer analysis yang hanya berfokus pada variabel jarak.

Buffer analysis, a fundamental function in a geographic information system (GIS), identifies areas by the surrounding geographic features within a given distance. Real-time buffer analysis for large-scale spatial data remains a challenging problem since the computational scales of conventional data-oriented methods expand rapidly with increasing data volume. In this paper, we introduce HiBuffer, a visualization-oriented model for real-time buffer analysis. An efficient buffer generation method is proposed which introduces spatial indexes and a corresponding query strategy. Buffer results are organized into a tile-pyramid structure to enable stepless zooming. Moreover, a fully optimized hybrid parallel processing architecture is proposed for the real-time buffer analysis of large-scale spatial data. Experiments using real-world datasets show that our approach can reduce computation time by up to several orders of magnitude while preserving superior visualization effects. Additional experiments were conducted to analyze the influence of spatial data density, buffer radius, and request rate on HiBuffer performance, and the results demonstrate the adaptability and stability of HiBuffer. The parallel scalability of HiBuffer was also tested, showing that HiBuffer achieves high performance of parallel acceleration. Experimental results verify that HiBuffer is capable of handling 10-million-scale data.

We report a case of congenital toxoplasmosis in a male child who presented at 1 month 21 days of life. He had a past history of meningitis on third day of life which resolved with intravenous antibiotics. This time, the child presented with progressive enlargement of head and CSF (Cerebrospinal fluid) showed elevated protein levels with cellular reaction and CT scan showed dilated ventricular system with aqueductal obstruction and multiple ring-enhancing lesions in bifrontal and bioccipital regions with a right porencephalic cyst. Repeat CSF after 14 days of intravenous antibiotics showed elevated protein with no cellular reaction. Fundus examination was normal. Toxoplasma blood serology (IgG and IgM) in baby and mother were positive. The child received treatment with Pyrimethamine, Clindamycin, Folinic acid and Prednisolone. CSF parameters got normalized and multiple ring-enhancing lesions disappeared on repeat CT scan. He underwent a Ventriculo-Peritoneal shunt surgery for the hydrocephalus and was discharged in a stable condition.
