Basement membranes can help determine pathways of migrating axons. Although members of the nidogen (entactin) protein family are structural components of basement membranes, we find that nidogen is not required for basement membrane assembly in the nematode Caenorhabditis elegans. Nidogen is localized to body wall basement membranes and is required to direct longitudinal nerves dorsoventrally and to direct axons at the midlines. By examining migration of a single axon in vivo, we show that nidog

Recently, research on service workers' emotional labor has received considerable attention, both in theory and practice. Emotional labor has been reported to cause both stress and burnout in service workers, eventually leading to a decrease in organizational productivity. In this context, there is also a growing interest in identifying ways to reduce such burnout. This study aimed to examine the influence of emotional labor and job demands⁻resources (JD⁻R) on service workers' burnout. Specifical

The world is turning into a risky society. Although modernization based on the developments in science and technology has increased individuals' well-being and wealth, the perceived risk toward the complex technological system has increased. In a risky society, social accidents amplify the existing fear among individuals. It is generally assumed that each value, perception, and resource influences the fear of risk. However, very few studies have tested these three factors together within an inte

False information about COVID-19 is being produced and disseminated on a large scale, impeding efforts to rapidly impose quarantines. Thus, in addition to the COVID-19 pandemic itself, an infodemic related with it is leading to social crises. This study therefore investigates who believes the misinformation that is being produced in the context of COVID-19. We choose two main factors—risk perception factor, so called psychometric paradigm, and communication factor—as independent variables that c

Arabidopsis seedlings increased extracellular ATP (exATP) concentrations transiently in extracellular matrix (ECM) under hypertonic stresses. The increased transcription levels of two apyrase genes, AtAPY1 and AtAPY2, in accordance with exATP accumulation, suggests active regulation of exATP concentration. Arabidopsis seedlings subjected to hypertonic stresses survived after incubation with beta,gamma-methyleneadenosine-5'-triphosphate, which usually causes cell death through competitive exclusi

Tuberous sclerosis complex (TSC) is associated with neurodevelopmental abnormalities, including defects in neuronal migration. However, the alterations in cell signaling mechanisms critical for migration and final positioning of neurons in TSC remain unclear. Our detailed cellular analyses reveal that reduced Tsc2 in newborn neurons causes abnormalities in leading processes of migrating neurons, accompanied by significantly delayed migration. Importantly, we demonstrate that Reelin-Dab1 signalin

One of the serious mental disorders where people interpret reality in an abnormal state is schizophrenia. A combination of extremely disordered thinking, delusion, and hallucination is caused due to schizophrenia, and the daily functions of a person are severely disturbed because of this disorder. A wide range of problems are caused due to schizophrenia such as disturbed thinking and behaviour. In the field of human neuroscience, the analysis of brain activity is quite an important research area

Emotional awareness perception is a largely growing field that allows for more natural interactions between people and machines. Electroencephalography (EEG) has emerged as a convenient way to measure and track a user's emotional state. The non-linear characteristic of the EEG signal produces a high-dimensional feature vector resulting in high computational cost. In this paper, characteristics of multiple neural networks are combined using Deep Feature Clustering (DFC) to select high-quality att

Countries around the world are expanding their investment in the new and renewable energy industry for strengthening energy security, improving air pollution, responding to climate change, and tackling energy poverty. In Korea, with the nuclear phase-out declaration in 2017, the government has announced a policy to expand the ratio of new and renewable energy from 4.7% to 20% by 2030. This study examines a floating photovoltaic power generation system, which is a new and renewable energy source.

This study aims to examine the degree of direct or indirect impact of quality and quantity of government on public health. It is a very important topic in that previous studies did not consider the role of government; they focused on the impact of national economic, social, and political factors on public health, therefore, disregarding the governmental factors. We measured the quantity of government by public expenditure on heath (i.e., rate of share of government budget to gross domestic produ

This study was conducted to investigate the correlations between social-emotional competence (SEC) and academic achievement (AA) among nursing students and to compare students' level of each core skill of SEC (critical thinking disposition, self-directed learning, creativity, emotional intelligence, problem-solving, and collaboration) and academic achievement (clinical performance and subjective academic achievement). A cross-sectional design was adapted. Data were collected from 195 nursing stu
