Effects of Yachting Motivation on Yachting Satisfaction and Re-Yachting Intention.

It is clear that yachting tourists are motivated to spend their leisure time at sea. However, few studies have determined the relationship between tourists' motivation and satisfaction with yachting, and re-yachting intention. Furthermore, the purpose of this study was to examine the relationships among yachting motivation, yachting satisfaction, and re-yachting intention.

Do the determinants of COVID-19 transmission differ by epidemic wave? Evidence from U.S. counties.

This paper uses data from the United States to examine determinants of the spread of COVID-19 during three different epidemic waves. We address how sociodemographic and economic attributes, industry composition, density, crowding in housing, and COVID-19-related variables are associated with the transmission of COVID-19. After controlling for spatial autocorrelation, our findings indicate that the percentage of people in poverty, number of restaurants, and percentage of workers teleworking were associated with the COVID-19 incidence rate during all three waves.

Enhancing the conductivity of PEDOT:PSS films for biomedical applications via hydrothermal treatment.

This paper reports a new biocompatible conductivity enhancement of poly (3,4-ethylenedioxythiophene):poly (styrene sulfonate) (PEDOT:PSS) films for biomedical applications. Conductivity of PEDOT:PSS layer was reproducibly from 0.495 to 125.

Effects of healthcare interventions on psychosocial factors of patients with multimorbidity: A systematic review and meta-analysis.

Purpose: A systematic review and meta-analysis was conducted to assess the types of healthcare intervention programs offered to patients with multimorbidity and their effects on key psychosocial factors.

Methods: For this systematic review and meta-analysis, we searched databases like Cochrane Library, PubMed, Embase, CINAHL RISS, KISS, etc. for studies published between January 1, 2009, and April 30, 2019.

Diurnal and Seasonal Variations in the Effect of Urban Environmental Factors on Air Temperature: A Consecutive Regression Analysis Approach.

This study investigates the diurnal and seasonal variations in the effect of environmental features on air temperature in Seoul, Korea. We expect that this study will lead to the identification of factors that can be applied for urban heat island mitigation strategies in summer without leading to an unintended result in winter. As our dependent variable, we employed the smoothed 31-day moving average of air temperatures, where we controlled the seasonal variation by normalizing the values observed from 247 automatic weather stations (AWS) from 2015 to 2016.

Accurate, hysteresis-free temperature sensor for health monitoring using a magnetic sensor and pristine polymer.

Herein, a novel temperature sensor is proposed employing a planar Hall resistance (PHR) magnetic sensor, a magnet sheet, and an expanding polymer. It features a tunable temperature range, high linear sensitivity, accuracy, and cycling stability through 1000 cycles, and no thermal hysteresis. This new sensor is promising as a body temperature sensor.

Transcriptional profiling shows altered expression of wnt pathway- and lipid metabolism-related genes as well as melanogenesis-related genes in melasma.

Melasma is a commonly acquired hyperpigmentary disorder of the face, but its pathogenesis is poorly understood and its treatment remains challenging. We conducted a comparative histological study on lesional and perilesional normal skin to clarify the histological nature of melasma. Significantly, higher amounts of melanin and of melanogenesis-associated proteins were observed in the epidermis of lesional skin, and the mRNA level of tyrosinase-related protein 1 was higher in lesional skin, indicating regulation at the mRNA level.

Comparison of effect of premixed lidocaine in propofol with or without ketorolac pretreatment with placebo on reducing pain on injection of propofol: A prospective, randomized, double-blind, placebo-controlled study in adult Korean surgical patients.

Background: Pain on injection of propofol is a common adverse event.

Objective: The aim of this study was to investigate the effect of a combination of ketorolac pretreatment and premixed lidocaine in propofol compared with placebo on propofol injection pain.

Methods: In this prospective, randomized, double-blind, placebo-controlled study, Korean patients scheduled for elective plastic surgery were randomized to 1 of 3 groups.

Efficacy of combination intravenous lidocaine and dexamethasone on propofol injection pain: a randomized, double-blind, prospective study in adult Korean surgical patients.

Background: Pain on injection is a common adverse effect with propofol used for general anesthesia.

Objectives: The aims of this study were to evaluate the analgesic effect of dexamethasone during propofol injection and investigate whether a combination of dexamethasone and lidocaine produced additional analgesic efficacy compared with either treatment alone.

Methods: In a double-blind, prospective trial, patients scheduled to undergo elective plastic surgery were randomized to receive lidocaine 20 mg, dexamethasone 6 mg, combination lidocaine 20 mg and dexamethasone 6 mg, or normal saline with venous occlusion for 1 minute, followed by administration of 25% of the total calculated dose of propofol (2.
