Spatial communication systems across languages reflect universal action constraints.

The extent to which languages share properties reflecting the non-linguistic constraints of the speakers who speak them is key to the debate regarding the relationship between language and cognition. A critical case is spatial communication, where it has been argued that semantic universals should exist, if anywhere. Here, using an experimental paradigm able to separate variation within a language from variation between languages, we tested the use of spatial demonstratives-the most fundamental and frequent spatial terms across languages.

Social distancing and prosocial behaviors: The replenishing effect of intense visual stimulation.

COVID-19 has disrupted lives across the world. This research investigates the psychological and behavioral consequences of social distancing, which is being globally practiced to contain its spread. Using seven experiments, we document the moderating role of high-intensity visual stimulation on social distancing's effect on psychologically distressed individuals' prosocial intentions and behaviors.

Discovering microbe-disease associations from the literature using a hierarchical long short-term memory network and an ensemble parser model.

With recent advances in biotechnology and sequencing technology, the microbial community has been intensively studied and discovered to be associated with many chronic as well as acute diseases. Even though a tremendous number of studies describing the association between microbes and diseases have been published, text mining methods that focus on such associations have been rarely studied. We propose a framework that combines machine learning and natural language processing methods to analyze the association between microbes and diseases.

Assessment of early discomfort and wound healing outcomes after periodontal surgery with and without enamel matrix derivative: an observational retrospective case-control study.

Objective: The aim of this study was to evaluate and compare early postoperative discomfort and wound healing outcomes between patients who underwent periodontal surgery with and without enamel matrix derivative (EMD), using retrospective questionnaires and postoperative clinical examinations.

Materials And Methods: All enrolled patients filled out the self-report questionnaire after suture removal. The severity and duration of subjective pain and swelling were evaluated using visual analog scale (VAS) scores and wound healing parameters (dehiscence/fenestration, spontaneous bleeding, persistent swelling, and ulceration).

Trends in the incidence of tooth extraction due to periodontal disease: results of a 12-year longitudinal cohort study in South Korea.

Purpose: This study evaluated trends in tooth extraction due to acute and chronic periodontal disease (PD) using data from the National Health Insurance Service-National Sample Cohort for 2002-2013.

Methods: A random sample of 1,025,340 individuals was selected as a representative sample of the population, and a database (DB) of diagnostic and prescription codes was followed up for 12 years. We used multivariate logistic regression analysis to assess the incidence of total extraction (TE), extraction due to periodontal disease (EPD), and immediate extraction due to periodontal disease (IEPD) according to sociodemographic factors (sex, age, household income, health status, and area of residence).

Effect of the tight fitting net on fit performance in single-use filtering facepieces for Koreans.

To get a better fit performance of filtering facepieces, a tight fitting net (TFN) was invented. This study was carried out to evaluate whether the TFN improves fit performance using a quantitative fit test (QNFT). The existing mask was of cup type with an aluminum clip on the nose bridge.
