Many English for Specific Purposes (ESP) programs focus on students’ oral proficiency and lack the content needed to assist students to develop lexical compilation for use in real workplace contexts. The current study will build upon the existing literature by developing pedagogy to assist students in their workplace readiness, focusing on a strong practical command of relevant English vocabulary. The research focuses on the pedagogy two professors incorporated in their English for employment courses, when teaching employment-related concept vocabulary. A qualitative case study of two foreign professors in the department of English in two Korean universities guided the current study. Pre-made recorded video lectures, live online class sessions with students, lesson plans and class materials were collected for data analysis. The study then focused on determining representative patterns in the professors’ teaching methods. Pedagogy that extended career specific concept vocabulary into authentic English conversation with three main steps was found. Firstly, students were taught concept vocabulary. Secondly, the vocabulary was then combined in speaking activities where students not only had to solve scenarios but also were required to expand on the given forms of words and language expressions. Lastly, the students had extended authentic conversations in English, using the target concept vocabulary learnt. Educational implications have been discussed. (211 words)

Golf and Skin Health: A Narrative Review

Allan G. Matthews(Allan G. Matthews ),Hannah Preston(Hannah Preston ),Andrew Murray(Andrew Murray ),Roger Hawkes(Roger Hawkes ) 사피엔시아 2018 Exercise Medicine Vol.2 No.-

Objectives: Recent studies have reported that playing golf has overall physical and mental health benefits. Through being placed in the sun for extended periods of time, the golfing population faces an increased risk of ultraviolet radiation (UVR) associated skin problems, most importantly skin cancer. Our aim was to collate and summarise current literature on the relationship between golf and skin cancer. Methods: We searched multiple web-based, health-focused databases (Medline, Embase, Cinahl, Web of science, Scopus, Sportdiscus, UK clinical trials, Current controlled trials and Prospero) to identify records. Relevant papers were critically appraised and reported using a descriptive analysis. Results: A total of 11 studies are included in the review. Golf is associated with relatively more UVR exposure than other outdoor activities such as fishing, tennis, pool swimming, cricket, gardening, ‘sun-worshipping’ and sailing. Calculated relative risk of non- melanoma skin cancer, based on cumulative UV exposure, is higher in golfers than non-golfers. Mid morning tee-times or playing golf between 11am -3pm associated with highest UVR exposures. Golfers can be exposed to potentially harmful levels of UVR during play in winter at some latitudes. Vertex (scalp), shoulders, back, back of neck and posterior arms exposed to more UVR than front of body during play. Common golf attire is of limited value in protecting the neck. Targeted skin cancer skin cancer prevention and early detection campaigns are well received among the golfing population. Conclusions: Overall, playing golf is associated with longevity and both physical and mental health benefits. Studies to date indicate that golfers (professionals > recreational players) are exposed to potentially harmful levels of UVR during play, but the true morbidity/mortality associated with this exposure is not known. Playing golf should be encouraged in all age groups, though golfers, the golf industry and policy makers should act to minimize the harmful effects of UVR exposure, and have they have ability to also be hugely influential on an important public health message.

Limitations and artifacts in shear-wave elastography of the liver

Matthew Bruce,Orpheus Kolokythas,Giovanna Ferraioli,Carlo Filice,Matthew O’Donnell 대한의용생체공학회 2017 Biomedical Engineering Letters (BMEL) Vol.7 No.2

Recent studies have shown that real-time, twodimensionalshear-wave elastography (2D-SWE) canmonitor liver fibrosis by measuring tissue elasticity (i.e.,elastic modulus). Two clinical studies of 2D-SWE in theliver have shown that there are several practical issues thatcan compromise quantitation of liver tissue elasticity. Bothgeneral ultrasound (US) limitations and limitations in the2D-SWE method itself resulted in significant variability inestimated liver elasticity. The most common US limitationswere: poor acoustic window, limited penetration, and rib/lung shadows. The most common 2D-SWE limitationswere: reverberations under the liver capsule, respiratory/cardiac motion, and vessel pulsation/loss of SWEsignal. Based on these studies, scan protocols have beenoptimized to minimize the influence of these limitations onliver elasticity quantification. These refined protocolsshould move non-invasive SWE closer to becoming thepreferred tool to diagnose and manage many chronic diseasesof the liver.

Effects of climate change on the physiology of giant kelp, Macrocystis pyrifera, and grazing by purple urchin, Strongylocentrotus purpuratus

Matthew B. Brown,Matthew S. Edwards,Kwang Young Kim 한국조류학회I 2014 ALGAE Vol.29 No.3

As global warming continues over the coming century, marine organisms will experience a warmer, more acidic ocean. Although these stressors may behave antagonistically or synergistically and will impact organisms both directly (i.e., physiologically) and indirectly (i.e., through altered species interactions), few studies have examined the complexities of these effects in combination. To address these uncertainties, we examined the independent and combined effects of elevated temperature and pCO2 on the physiology of the adult sporophyte stage of giant kelp, Macrocystis pyrifera, and the grazing of the purple sea urchin Strongylocentrotus purpuratus. While elevating pCO2 alone had no effect on M. pyrifera growth or photosynthetic carbon uptake, elevating temperature alone resulted in a significant reduction in both. However, when M. pyrifera was grown under elevated temperature and pCO2 together, growth and photosynthetic carbon uptake significantly increased relative to ambient conditions, suggesting an interaction of these factors on photosynthetic physiology. S. purpuratus held under future conditions generally exhibited reduced growth, and smaller gonads than urchins held under present-day conditions. However, urchins fed kelp grown under future conditions showed higher growth rates, partially ameliorating this effect. Feeding rates were variable over the course of the experiment, with only the first feeding rate experiment showing significantly lower rates for urchins held under future conditions. Together, these data suggest that M. pyrifera may benefit physiologically from a warmer, more acidic (i.e., higher pCO2) ocean while S. purpuratus will likely be impacted negatively. Given that kelp-urchin interactions can be important to kelp forest structure, changes to either of these populations may have serious consequences for many coastal environments.

[Purpose] This study investigated the effects of marine phytoplankton supplementation (Oceanix®, Tetraselmis chuii ) on 1) maximal isometric strength and immune function in healthy humans following a one-week high-intensity resistance-training program and 2) the proinflammatory cytokine response to exercise in a rat model. [Methods] In the human trial, 22 healthy male and female participants were randomly divided into marine phytoplankton and placebo groups. Following baseline testing, participants underwent a 14-day supplement loading phase before completing five consecutive days of intense resistance training. In the rat model, rats were randomly divided into four groups (n=7 per condition): (i) control, (ii) exercise, (iii) exercise + marine phytoplankton (2.55 mg/kg/day), or (iv) exercise + marine phytoplankton (5.1 mg/kg/day). Rats in the exercising groups performed treadmill exercise 5 days per week for 6 weeks. [Results] In the human model, marine phytoplankton prevented significant declines in the isometric peak rate of force development compared to placebo. Additionally, salivary immunoglobulin A concentration was significantly lower following the resistance training protocol in the placebo group but not in the marine phytoplankton group. Marine phytoplankton in exercising rats decreased intramuscular levels and serum concentrations of tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) and intramuscular concentrations of malondialdehyde. [Conclusion] Marine phytoplankton prevented decrements in indices of functional exercise recovery and immune function. Mechanistically, these outcomes could be prompted by modulating the oxidative stress and proinflammatory cytokine response to exercise.

As global warming continues over the coming century, marine organisms will experience a warmer, more acidic ocean.

Background: The purpose of this study was to compare outcomes of patients who underwent bilateral total shoulder arthroplasties (TSAs) for osteoarthritis (OA) versus bilateral reverse shoulder arthroplasties (RSAs) for cuff tear arthropathy (CTA). Methods: Inclusion criteria were patients who underwent bilateral TSAs for OA or bilateral RSAs for CTA with at least 2 years of follow-up. Twenty-six TSA patients (52 shoulders) were matched 2 to 1 with 13 RSA patients (26 shoulders) by sex, age at first surgery, and time between surgeries. Outcomes measured were shoulder range of motion (ROM), complications, and patient-reported scores. Results: Preoperatively, TSA patients had significantly better forward elevation (FE) of both shoulders than RSA patients (dominant side [Dom]: 103° ± 32° vs. 81° ± 31°, p = 0.047; nondominant side [non-Dom]: 111° ± 28° vs. 70° ± 42°, p = 0.005) without significant differences in external (ER) or internal rotation (IR). Postoperatively, TSA patients had significantly better FE (Dom and non-Dom: 156° ± 12°, 156° ± 14° vs. 134° ± 24°, 137° ± 23°; p = 0.006, p = 0.019) and ER (42° ± 11°, 43° ± 10° vs. 24° ± 12°, 25° ± 10°; p < 0.001, p < 0.001) bilaterally and IR of their dominant arm (L1 vs. L4, p = 0.045). TSA patients had significantly better activities of daily living external and internal rotations (ADLEIR) scores (Dom and non-Dom: 35.3 ± 1.0, 35.5 ± 0.9 vs. 32.1 ± 2.4, 32.5 ± 2.2; p = 0.001, p = 0.001), American Shoulder and Elbow Surgeons scores (94.2 ± 8.4, 94.2 ± 8.2 vs. 84.7 ± 10.0, 84.5 ± 8.0; p = 0.015, p = 0.004), and Single Assessment Numerical Evaluation (SANE) scores (93.5 ± 7.6, 93.8 ± 11.8 vs. 80.5 ± 14.2, 82.3 ± 13.1; p = 0.014, p = 0.025), with no significant difference in visual analog scale pain scores (0.4 ± 1.0, 0.3 ± 1.0 vs. 0.7 ± 1.3, 0.8 ± 1.2) bilaterally. Conclusions: Overall, patients with bilateral TSAs and RSAs exhibited improved ROM and patient-reported outcomes. Those with bilateral TSAs had better functional outcomes than those with bilateral RSAs.

Comprehensive Experimental and Computational Spectroscopic Study of Hexacyanoferrate Complexes in Water: From Infrared to X-ray Wavelengths

Ross, Matthew,Andersen, Amity,Fox, Zachary W.,Zhang, Yu,Hong, Kiryong,Lee, Jae-Hyuk,Cordones, Amy,March, Anne Marie,Doumy, Gilles,Southworth, Stephen H.,Marcus, Matthew A.,Schoenlein, Robert W.,Mukame American Chemical Society 2018 The journal of physical chemistry. B, Condensed ma Vol.122 No.19

<P>We present a joint experimental and computational study of the hexacyanoferrate aqueous complexes at equilibrium in the 250 meV to 7.15 keV regime. The experiments and the computations include the vibrational spectroscopy of the cyanide ligands, the valence electronic absorption spectra, and Fe 1s core hole spectra using element-specific-resonant X-ray absorption and emission techniques. Density functional theory-based quantum mechanics/molecular mechanics molecular dynamics simulations are performed to generate explicit solute-solvent configurations, which serve as inputs for the spectroscopy calculations of the experiments spanning the IR to X-ray wavelengths. The spectroscopy simulations are performed at the same level of theory across this large energy window, which allows for a systematic comparison of the effects of explicit solute-solvent interactions in the vibrational, valence electronic, and core-level spectra of hexacyanoferrate complexes in water. Although the spectroscopy of hexacyanoferrate complexes in solution has been the subject of several studies, most of the previous works have focused on a narrow energy window and have not accounted for explicit solute-solvent interactions in their spectroscopy simulations. In this work, we focus our analysis on identifying how the local solvation environment around the hexacyanoferrate complexes influences the intensity and line shape of specific spectroscopic features in the UV/vis, X-ray absorption, and valence-to-core X-ray emission spectra. The identification of these features and their relationship to solute-solvent interactions is important because hexacyanoferrate complexes serve as model systems for understanding the photochemistry and photophysics of a large class of Fe(II) and Fe(III) complexes in solution.</P> [FIG OMISSION]</BR>

Tandem Solar Cells from Solution-Processed CdTe and PbS Quantum Dots Using a ZnTe–ZnO Tunnel Junction

Crisp, Ryan W.,Pach, Gregory F.,Kurley, J. Matthew,France, Ryan M.,Reese, Matthew O.,Nanayakkara, Sanjini U.,MacLeod, Bradley A.,Talapin, Dmitri V.,Beard, Matthew C.,Luther, Joseph M. American Chemical Society 2017 Nano letters Vol.17 No.2

<P>We developed a monolithic CdTe–PbS tandem solar cell architecture in which both the CdTe and PbS absorber layers are solution-processed from nanocrystal inks. Due to their tunable nature, PbS quantum dots (QDs), with a controllable band gap between 0.4 and ∼1.6 eV, are a promising candidate for a bottom absorber layer in tandem photovoltaics. In the detailed balance limit, the ideal configuration of a CdTe (<I>E</I><SUB>g</SUB> = 1.5 eV)–PbS tandem structure assumes infinite thickness of the absorber layers and requires the PbS band gap to be 0.75 eV to theoretically achieve a power conversion efficiency (PCE) of 45%. However, modeling shows that by allowing the thickness of the CdTe layer to vary, a tandem with efficiency over 40% is achievable using bottom cell band gaps ranging from 0.68 and 1.16 eV. In a first step toward developing this technology, we explore CdTe–PbS tandem devices by developing a ZnTe–ZnO tunnel junction, which appropriately combines the two subcells in series. We examine the basic characteristics of the solar cells as a function of layer thickness and bottom-cell band gap and demonstrate open-circuit voltages in excess of 1.1 V with matched short circuit current density of 10 mA/cm<SUP>2</SUP> in prototype devices.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2017/nalefd.2017.17.issue-2/acs.nanolett.6b04423/production/images/medium/nl-2016-04423k_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl6b04423'>ACS Electronic Supporting Info</A></P>
