Workplace Violence Experienced by Personal Care Workers in a District in Seoul, Republic of Korea: A Comparison Study with Office and Service Workers.

This study compared the level of workplace violence experienced by personal healthcare workers in a district in Seoul, Republic of Korea, with those experienced by workers in office or service jobs. We matched 150 personal care workers with 150 office workers and 150 service workers using a propensity score. Workplace violence was categorized into psychological violence and physical violence.

The effects of a balloon-blowing exercise in a 90/90 bridge position using a ball on the pulmonary function of females in their twenties.

[Purpose] This study was conducted to investigate pulmonary function before and after the performance of a balloon-blowing exercise in a 90/90 bridge position using a ball among female university students in their twenties. [Participants and Methods] Participants were randomly assigned to the control group, which performed the bridge position using hip and knee flexion on a ball with a diaphragm respiratory exercise, or the experimental group, which performed a 90/90 bridge using a ball with a balloon exercise. The exercise programs were conducted 30 minutes a day, five times a week for four weeks.

The effects of place running exercises on the pulmonary function of normal adults.

[Purpose] The purpose of this study was to determine whether place running exercises increase the pulmonary function of normal adults. [Subjects and Methods] Thirty normal adults in their 20s were randomly assigned to an experimental group (n=15) or a control group (n=15). Over the course of four weeks, the experimental group participated in place running exercise for 30 minutes five times per week.

An analysis of pulmonary function in different lying positions in the 20's normal adults.

[Purpose] The purpose of this study was to study the changes in pulmonary functions in relation to lying positions of experimental participants. [Subjects and Methods] Twenty participants participated in this experiment. Measurements were taken in the supine position, the left side-lying position, the right side-lying position, and the prone position.

Analysis of the pulmonary functions of normal adults according to pillow height.

[Purpose] The purpose of this study is to examine changes in pulmonary functions in relation to the sleeping positions of the experimental subjects. [Subjects and Methods] The subjects for this study were twenty randomly selected males and females from K University. Measurements were taken in the supine position at three different pillow heights: 0 cm, 5 cm, and 10 cm.

The effects on the pulmonary function of normal adults proprioceptive neuromuscular facilitation respiration pattern exercise.

[Purpose] The purpose of this study was to determine whether proprioceptive neuromuscular facilitation (PNF) respiration exercise increases the pulmonary function of normal adults. [Subjects and Methods] Twenty-eight normal adults in their 20s were randomly assigned to an experimental group (n=14) or control group (n=14). Over the course of four weeks, the experimental group participated in PNF respiration pattern exercises for 30 minutes three times per week.

Caffeic acid phenethyl ester promotes anti-inflammatory effects by inhibiting MAPK and NF-κB signaling in activated HMC-1 human mast cells.

Context: Caffeic acid phenethyl ester (CAPE), an active component of honeybee propolis, is known to have antioxidant, anti-inflammatory, and other beneficial medicinal properties. However, the molecular mechanisms underlying its anti-allergic effects in mast cells are unknown.

Objective: The purpose of the present study was to examine whether CAPE modulates the immunoglobulin E (IgE)-mediated local allergic reaction in animals, as well as to elucidate the effects of CAPE on mast cells in vitro.

Selective detection of endotoxin using an impedance aptasensor with electrochemically deposited gold nanoparticles.

Using a single-stranded DNA (ssDNA) aptamer exhibiting high binding affinity (Kd = 12 nM) to endotoxin as a probe, an impedance sensor where aptamer-conjugated gold nanoparticles (AuNPs) were electrochemically deposited on a gold electrode was fabricated and its performance in regard to endotoxin detection assessed. AuNPs have been employed widely as biosensors because of their unique physical and chemical properties. In order to maximize the performance of the impedance aptasensor on endotoxin detection, some critical factors affecting aptamer conjugation to AuNPs and target recognition ability (i.

Harnessing aptamers for electrochemical detection of endotoxin.

Lipopolysaccharide (LPS), also known as endotoxin, triggers a fatal septic shock; therefore, fast and accurate detection of LPS from a complex milieu is of primary importance. Several LPS affinity binders have been reported so far but few of them have proved their efficacy in developing electrochemical sensors capable of selectively detecting LPS from crude biological liquors. In this study, we identified 10 different single-stranded DNA aptamers showing specific affinity to LPS with dissociation constants (K(d)) in the nanomolar range using a NECEEM-based non-SELEX method.

Determination of endotoxin through an aptamer-based impedance biosensor.

Lipopolysaccharide (LPS) often referred to endotoxin is an undesirable impurity frequently entrained with various recombinant protein therapeutics and plasmid DNA (pDNA) vaccines of bacterial origin. The inherent toxicities (e.g.

Fabrication of polypyrrole nanorod arrays for supercapacitor: effect of length of nanorods on capacitance.

Arrays of polypyrrole nanorods were fabricated using an anodized aluminum oxide (AAO) template for use as supercapacitors. Gold was deposited on one side of the AAO template by thermoevaporation for use as an electrode and pyrrole was electrochemically polymerized, causing it to grow from the gold electrode into the AAO template. The length of the PPy nanorods was controlled by adjusting the applied charge, and nanorods with three different lengths were prepared: 1.

New strategy and easy fabrication of solid-state supercapacitor based on polypyrrole and nitrile rubber.

Solid state redox supercapacitors were fabricated using a solid polymer electrolyte, nitrile butadiene rubber (NBR)-KCI and chemically deposited polypyrrole (PPy) as the conducting polymer electrodes on both surfaces of a NBR film. The optimal conditions for the preparation of the PPy/NBR electrode were confirmed as functions of the uptake of pyrrole monomer into the NBR matrix as well as the immersion time in an oxidant solution. The morphology of the PPy-NBR-KCI capacitor was observed using scanning electron microscopy.
