ABSTRACT
INTRODUCTION: Mental health is defined as "a state of well-being in which the person realizes his or her own skills, can deal with the normal stresses of life, can work effectively and fruitfully, and is able to make a contribution to his or her community." Although mental health is essential to human survival, it is often given less attention than physical health in many parts of the world. OBJECTIVES: The aim of this study is to evaluate the rural community's awareness regarding mental health issues and the factors that contribute to them. MATERIALS AND METHODS: A cross-sectional study was undertaken in the rural community; 350 study subjects were selected from the village of Devarayasamudra by using convenient sampling, 350 households were selected, and household-level interviews were done using the Mental Health Knowledge Schedule questionnaire. Participants aged more than 18 were included in the study, and locked households, even after two visits, were excluded from the study. RESULTS: The median aggregate knowledge score was 31 (SD = 7.1), with the minimum and maximum values being 11 and 44 out of 45 knowledge items, respectively. The total knowledge score found that 178 (50.8%) respondents had insufficient mental health knowledge based on the percentage of the study population with a cut-off score below and above the median score. A multivariate logistic regression analysis confirmed that participants who were illiterate had 1.76 (1.15-2.26) times the chances of having insufficient knowledge compared to professionals, and this remained true even after adjusting for other variables as well. CONCLUSION: The present study concluded that more than 50% (50.8%) of the participants had inadequate awareness of mental health and mental illness. This highlights the need to spread awareness about mental health education among the general community.
ABSTRACT
We present a novel approach for the room-temperature fabrication of conductive traces and their subsequent site-selective dielectric encapsulation for use in flexible electronics. We have developed an aerosol-assisted atmospheric pressure plasma-based deposition process for efficiently depositing materials on flexible substrates. Silver nanowire conductive traces and silicon dioxide dielectric coatings for encapsulation were deposited using this approach as a demonstration. The paper substrate with silver nanowires exhibited a very low change in resistance upon 50 cycles of systematic deformation, exhibiting high mechanical flexibility. The applicability of this process to print conductive traces on nonconformal 3D objects was also demonstrated through deposition on a 3D-printed thermoplastic object, indicating the potential to combine plasma printing with 3D printing technology. The role of plasma here includes activation of the material present in the aerosol for deposition, increasing the deposition rate, and plasma polymerization in the case of inorganic coatings. The demonstration here establishes a low-cost, high-throughput, and facile process for printing electronic components on nonconventional platforms.
ABSTRACT
Controlled integration of features that enhance the analytical performance of a sensor chip is a challenging task in the development of paper sensors. A critical issue in the fabrication of low-cost biosensor chips is the activation of the device surface in a reliable and controllable manner compatible with large-scale production. Here, we report stable, well-adherent, and repeatable site-selective deposition of bioreactive amine functionalities and biorepellant polyethylene glycol-like (PEG) functionalities on paper sensors by aerosol-assisted, atmospheric-pressure, plasma-enhanced chemical vapor deposition. This approach requires only 20 s of deposition time, compared to previous reports on cellulose functionalization, which takes hours. A detailed analysis of the near-edge X-ray absorption fine structure (NEXAFS) and its sensitivity to the local electronic structure of the carbon and nitrogen functionalities. σ*, π*, and Rydberg transitions in C and N K-edges are presented. Application of the plasma-processed paper sensors in DNA detection is also demonstrated.
