The results of the Subjective Self Rating Test (SSRT) questionnaire in Information and Technology System Development section showed that workers experienced symptoms severe head, fatigue, drowsiness, yawning, forgetfulness, awkwardness stiffness. This indicates a problematic workload. study aims to see level mental workload each staff. method this used NASA-TLX. Based on calculations, it was fo...
Berkah Toys is one of the UMKM engaged in production surpets, dolls. mattresses and pillows that utilize HDP (High Density Padding) dakron (Silicon) as main raw materials. When sales are rising, owners will apply an excessive overtime policy, resulting a decrease worker attendance rate by 20%, which many 2-3 workers out total 13 workers. In addition to attendance, also causes fatigue workers, b...
Adult neurogenesis is maintained by self-renewable neural stem cells (NSCs). Their activity is regulated by multiple signaling pathways and key transcription factors. However, it has been unclear whether these factors interplay with each other at the molecular level. Here we show that SRY-box-containing gene 2 (Sox2) and nuclear receptor tailless (TLX) form a molecular network in adult NSCs. We...
Dysregulated expression of miR-219, a brain-specific microRNA, has been observed in neurodevelopmental disorders, such as schizophrenia (SCZ). However, its role in normal mammalian neural stem cells (NSCs) and in SCZ pathogenesis remains unknown. We show here that the nuclear receptor TLX, an essential regulator of NSC proliferation and self-renewal, inhibits miR-219 processing. miR-219 suppres...
The tailless (Tlx) gene encodes an orphan nuclear receptor that is expressed by neural stem/progenitor cells in the adult brain of the subventricular zone (SVZ) and the dentate gyrus (DG). The function of Tlx in neural stem cells of the adult SVZ remains largely unknown. We show here that in the SVZ of the adult brain Tlx is exclusively expressed in astrocyte-like B cells. An inducible mutation...
Background and aims: Modern technology has imposed more cognitive demands than physical demands to operators in most workplaces.The Increase of cognitive demands in real working conditions can have negative effect on the mental health and performance of operators. This study was coducted with the aim of subjective and objective evaluation of operators’ mental workload in a city traf...
MicroRNAs manifest significant functions in brain neural stem cell (NSC) self-renewal and differentiation through the post-transcriptional regulation of neurogenesis genes. Let-7b is expressed in the mammalian brain and regulates NSC proliferation and differentiation by targeting the nuclear receptor TLX, which is an essential regulator of NSC self-renewal. Whether let-7b and TLX act as importa...
Tlx belongs to a class of orphan nuclear receptors that underlies many aspects of neural development in the CNS. However, the fundamental roles played by Tlx in the control of eye developmental programs remain elusive. By using Tlx knock-out (KO) mice, we show here that Tlx is expressed by retinal progenitor cells in the neuroblastic layer during the period of retinal layer formation, and it is...
BACKGROUND Falls and fall-related injuries are increasingly serious issues among elderly inpatients due to population aging. The bed-exit alarm has only previously been evaluated in a handful of studies with mixed results. Therefore, we evaluated the effectiveness of a modular bed absence sensor device (M-BAS) in detecting bed exits among older inpatients in a middle income nation in East Asia....
