Binge Drinking and Obesity-Related Eating: The Moderating Roles of the Eating Broadcast Viewing Experience among Korean Adults

Recently, there has been a notable rise in binge drinking and in the popularity of eating broadcasts via TV and online platforms, especially in Korea. This study analyzed the moderating effect of the eating broadcast viewing experience on the relationship between binge drinking and obesity-related eating behaviors. Cross-sectional self-reported online survey data were collected from 1125 Korean adults. Moderation models for restrained, emotional, and external eating behaviors were tested using moderation analyses with Hayes’s PROCESS version 3.5 compatible with SPSS. As a result, the eating broadcast viewing experience moderated the relationship between binge drinking frequency and external eating (Fchange = 2.686, p = 0.045). More frequent binge drinking was associated with a higher level of external eating in participants who only watched online eating broadcasts, especially among women. Participants in their twenties showed the same above association; additionally, those who only watched TV eating broadcasts showed an inverse association, indicating that more frequent binge drinking was associated with a lower level of external eating. Consequently, an eating broadcast viewing experience was one of the environmental factors associated with binge drinking that influences obesity-related eating behaviors

Structural, Electrical and Magnetic Properties of Diluted Magnetic Semiconductor Si1−xMnxTe1.5 Single Crystals

We studied the dependence of the magnetic properties on the Mn concentration of IV-VI diluted magnetic semiconductor Si$_{1-x}$Mn$_{x}$Te$_{1.5}$ single crystals prepared by using the vertical Bridgman technique. X-ray studies showed that the crystal structure was hexagonal. The magnetization measurement of Si$_{1-x}$Mn$_{x}$Te$_{1.5}$ showed a ferromagnetic ordering up to 80 K. With increasing Mn concentration, the saturation magnetization increased and the coercive field increased, as shown in the hysteresis loop. For $x$ = 0.20 and 0.31, a slope change in the resistivity was observed around 80 K and corresponded to a ferromagnetic (FM)-paramagnetic (PM) phase transition.ope

Magneto-optical properties for bulk Cd0.63−yMn0.37HgyTe single crystals

We investigated the magneto-optical properties of diluted magnetic semiconductor Cd1-x-yMnxHgyTe (x similar to 0.37) single crystals grown using a vertical Bridgman method. This material crystallizes in the zinc-blende structure for values of y = 0.03). An anomalous behavior was also observed in the magnetic susceptibility and electrical resistivity. Faraday rotation as a function of photon energy with various Hg compositions for CdMnHgTe in the temperature range of 10-300 K has been measured. The Verdet dispersion curves were enhanced near the fundamental band gap energy. The Verdet constant becomes larger since the effect of the sp-d exchange interaction is enhanced as the temperature is lowered. At 10 K, the Verdet constants of the Faraday rotation for the samples with y=0, 0.01, 0.03, 0.05, and 0.07 were observed to be -1.09, -2.57, -3.94, -0.97, and -0.87 deg/G cm at 613 nm, respectively. The Verdet constant showed a maximum for the sample with y=0.03, and the value is approximately four times larger than that of the Cd0.63Mn0.37Te crystal. The Verdet constant has a maximum around Hg compositions with y similar to 0.03, and this result agrees well with the behavior of the magnetic susceptibility. This result reflects that Hg ion mediates and enhances the spin-spin interaction between Mn2+ ions with increasing Hg composition up to y similar to 0.03.ope

Magnetic and electrical properties of new magnetic phase in Si1-xMnx crystals

We have investigated the magnetic and electrical transport properties of Si1-xMnx single crystals grown by the vertical Bridgman method. The alloys with Mn concentrations up to x=0.64 have weak ferromagnetic ordering around TC???30 K. However, Si0.25Mn0.75 alloys show weak ferromagnetic ordering at 70 K and antiferromagnetic ordering at 104 K, which is confirmed by magnetization and electrical transport studies.ope

Gender-differences in predictors for time to metabolic syndrome resolution: A secondary analysis of a randomized controlled trial study.

Understanding gender differences in health-related behaviors and their impacts is a crucial aspect of effective primary care. We studied gender-based differences in predictors of metabolic syndrome (MetS) resolution among newly diagnosed MetS patients. This study was a secondary analysis of a prospective clinical trial study comprising of 637 middle-aged and older adults (226 men and 411 women) who underwent a regular health checkup and were newly diagnosed with MetS at 16 different health clinics of 14 metropolitan cities and provinces. We conducted Cox proportional hazard analysis to estimate cumulative probability of MetS resolution within a 12-month observation period. Among the 637 patients, 47.6% of participants achieved MetS resolution. The resolution rate was similar among men and women (44.7% and 49.1%, respectively, P = 0.320). Low household income (Hazard ratio = 2.62, 95% confidence interval: 1.13-6.08) and current employment (2.29, 1.26-4.13) were associated with a higher cumulative probability of MetS resolution in men than in women. For women, however, longer sleeping hours (1.18, 1.04-1.34) and living with a partner (1.58, 1.06-2.35) were positive predictors of MetS resolution. Being overweight (0.63, 0.44-0.89) was associated with lower cumulative probability of MetS resolution in women than in men. The factors associated with cumulative probability of MetS resolution within the 12-month follow-up were different between men and women. These findings facilitate further exploration on gender-based differences in risk factors for less optimal improvements in MetS

Spectroscopic ellipsometric studies of the dielectric function of Cd1–x–yMnxFeyTe single crystals

Cd1-x-yMnxFeyTe single crystals grown by the vertical Bridgman method have been studied by measuring the complex dielectric function using spectroscopic ellipsometry in the 1.5 similar to 5.5 eV photon energy range at room temperature. The CP energy parameters of the E-0, E-1, E-1 + Delta(1), and E-2 structures were determined by fitting the second-derivative spectra (d(2)epsilon/domega(2)) with a theoretical model, i.e., the standard critical point (SCP) line shapes. The E-1, E-1 + Delta(1), and E-2 energies decreased with increasing Fe composition y, which is due to the hybridization effect of the valence and conduction bands in Cd1-xMnxTe with Fe 3d levels.

Photoluminescence of Zn1−xBexSe Films Grown by Using Molecular Beam Epitaxy

We report a systematic investigation of band-edge photoluminescence of the II-VI wide band-gap semiconductor Zn1-xBexSe for a series of Be compositions (0 < x < 0.4). The specimens investigated were in the form of thin films fabricated by using molecular beam epitaxy (MBE). The near band-edge emissions of free excitons (designated as FX) were systematically investigated as a function of temperature and of alloy composition. From the temperature dependence of the free exciton peak, the Varshni temperature parameters ?? and ?? were found to increase with increasing Be concentration x. From the temperature dependence of the FWHM of the free exciton FX emission line, the broadening factors ??(T) were determined from a fit to the data. Furthermore, the activation energies of thermal quenching for the EA peak were obtained from the temperature dependence of the free exciton peaks, and were found to decrease with increasing Be concentration.ope

Magnetic, Structural, and Electrical Properties of Si1&#8722;xMnx Single Crystals

We have investigated the magnetic and the electrical transport properties of Si 1-xMn x (x = 0.5 and 0.75) single crystals grown by using the vertical Bridgman method. The alloys with the Mn concentration x = 0.5 have weak ferromagnetic ordering around T C &#8771;30 K. However, Si 0.25Mn 0.75 alloys show weak ferromagnetic ordering at 70 K and antiferromagnetic ordering at 104 K, which is confirmed by magnetization, electrical transport, and neutron diffraction studies. The conductivities appear to be n-type for samples with x = 0.5 and p-type for x = 0.75.ope
