Abstrak COVID -19 berdampak besar pada pengelolaan layanan kesehatan khususnya di rumah sakit. Sebagai garda terdepan dalam mengatasi pandemic COVID-19 sakit dituntut tetap melayani dan mengobati pasien khusunya yang teinfeksi COVID-19. Faktor-faktor seperti jumlah semakin meningkat, meningkatnya jam kerja, kelelahan, rasa bahaya ketidakpastian, serta kurangnya pengetahuan tentang prosesnya men...

Microsoft SQL Server was successful for many years for transaction processing and decision support workloads with neither merge join nor hash join, relying entirely on nested loops and index nested loops join. How much difference do additional join algorithms really make, and how much system performance do they actually add? In a pure OLTP workload that requires only record-to-record navigation...

OBJECTIVE To understand cognitive function of an expert surgeon in various surgical scenarios while performing robot-assisted surgery. MATERIALS AND METHODS In an Internal Review Board approved study, National Aeronautics and Space Administration-Task Load Index (NASA-TLX) questionnaire with surgical field notes were simultaneously completed. A wireless electroencephalography (EEG) headset wa...

To obtain good system performance, a DBA must choose a set of indices that is appropriate for the workload. The system can aid in this challenging task by providing recommendations for the index configuration. We propose a new index recommendation technique, termed semi-automatic tuning, that keeps the DBA “in the loop” by generating recommendations that use feedback about the DBA’s preferences...

The NASA Task Load Index (NASA − TLX) and the Workload Profile (WP ) are likely the most employed instruments for subjective mental workload (MWL) measurement. Numerous areas have made use of these methods for assessing human performance and thusly improving the design of systems and tasks. Unfortunately, MWL is still a vague concept, with different definitions and no universal measure. This re...

This paper presents a case study to introduce a new technique for identifying and comparing cognitive strategies. The technique integrates eye movements with the Index of Cognitive Activity, a psychophysiological measurement of cognitive workload derived from changes in pupil dilation. The first part of the paper describes the technique and its constituent elements. The second part describes th...

In this paper, we describe main-memory management and the most important buffers in the Vagabond server, a transaction-time temporal object database system currently under development at the Norwegian University of Science and Technology. Special emphasis is given to fine granularity buffering of OID index entries and objects. In order to make it easier for the system to adaptively change the s...
