Authors: Gomes Maria José Carli , Kerbauy Rachel Rodrigues
Published: June 2018

Este estudo investigou, nos relatos de pessoas gagas não submetidas à terapia para a gagueira, as estratégias de enfrentamento empregadas para superar as dificuldades e enfrentar as situações de comunicação. Os participantes foram três homens e uma mulher, com idades variando entre 31 e 54 anos, gagos desde a infância, sem nenhuma outra história de doença neurológica ou dano cerebral. As entrevistas foram gravadas em áudio e amostras de fala dos participantes, nas situações de conversa espontânea e de leitura, foram gravadas em vídeo. Essas amostras foram utilizadas na avaliação da severidade da gagueira. A análise dos resultados mostrou que os participantes adquiriram, ao longo de suas vidas, estratégias de enfrentamento eficientes para lidar com sua fala, como as instruções, a preparação prévia do conteúdo da fala e o parar e recomeçar. Muitas das estratégias de enfrentamento, utilizadas pelos participantes, encontram respaldo na literatura especializada, em termos de eficácia.

Published: June 2018

A categorização do conteúdo verbal do processo terapêutico pode ser vista como um treino intraverbal. Assim, a avaliação das variáveis envolvidas neste treino pode fornecer informações sobre as variáveis relevantes na atividade de categorização. Este trabalho analisou os procedimentos e resultados de estudos que visavam ao treino de respostas intraverbais, buscando identificar variáveis relevantes no estabelecimento do comportamento intraverbal, e conseqüentemente da categorização. As seguintes variáveis foram identificadas: presença de dicas textuais; uso de exemplos, de forma especial a exposição a um procedimento de instruções de múltiplos exemplos; e, no contexto das relações instrucionais, exposição a tarefas de definição antes de iniciar tarefas de identificação de exemplos, bem como a identificação das características críticas e definidoras do conceito trabalhado. Estas variáveis parecem estar relacionadas diretamente com aquelas identificadas nas pesquisas da área de categorização do conteúdo do processo terapêutico, sugerindo que elas devem ser consideradas no desenvolvimento dos estudos relacionados com esta área.

Effect of feeding whole cottonseed as a supplement on digestibility and rumen fermentation characteristics of sheep
Authors: Ismartoyo Mr
Published: June 2018

An experiment was conducted in vivo to investigate the effects on the apparent feed digestibility and rumen fermentation of feeding whole cottonseed (WCS) as a supplement for sheep fed grass hay (GH). Four different diets (T1, T2, T3 and T4) were used as GH alone, GH plus 150, 300 and 500 g WCS d-1 on fresh basis. The main objectives of the in vivo experiment were to examine digestibility and rumen fermentation characteristics (pH, ammonia and VFA concentration) of sheep fed four diets. The results of this experiment indicated that supplementation of WCS at a level of 500 g d-1 (0.37 of the diet) with GH reduced DM, ADF and NDF digestibility. There was no statistically significant effect on total rumen VFA, but the molar proportions of acetate, propionate and butyrate were altered by the addition of highest rate of WCS. These results suggested that WCS might have reduced the number or activity of cellulolytic rumen microorganisms.Bang. J. Anim. Sci. 2017. 46 (4): 239-243

Published: June 2018

This study was conducted to evaluate microbial load of beef meat during handling and selling in market. Total 12 samples were collected from K.R market, Sheshmore market, Kewatkhali bazaar and Mymensingh Sadar market. These samples were subjected to determine Total Viable Count (TVC), Total Coliform Count (TCC) and Total Yeast and Mould Count (TYMC) by using standard protocol at 0 hr, 2hrs and 5hrs time intarvel. The microbial counts of beef at different markets were high but there were no significant differences (p>0.05) among the markets. In every cases with the increased of time interval all types of microbial count increased significantly (p<o.o1) than the initial time. Microbial contamination of beef occurs as plant workers and machinery repeatedly touch contaminated surfaces and the carcass. Thoughtful design of operating procedures, especially for flaying and evisceration, can greatly reduce this problem. Frequent washing and sanitizing of hands, tools, and machinery is required in order to remove bacteria before they reach the exposed surface of the carcass.Bang. J. Anim. Sci. 2017. 46 (4): 244-248

Magnetic solid-phase extraction is an effective and convenient sample pretreatment technique that has received considerable interest in recent years. A lot of research indicated that magnetic nanocarbon-material-based composites have good application prospects as adsorbents for magnetic solid-phase extraction of pesticides. Herein, a novel zeolitic imidazolate framework based on magnetic multiwalled carbon nanotubes (M-M-ZIF-67) has been prepared as an adsorbent for magnetic solid-phase extraction of nine organochlorine pesticides from agricultural irrigation water samples. The obtained M-M-ZIF-67 material possessed porous surfaces and super-paramagnetism due to the utilization of magnetic multiwalled carbon nanotubes as the magnetic kernel and support. To evaluate the extraction performance of the M-M-ZIF-67, the main parameters that affected the extraction efficiency were researched. Under the optimal conditions, a good linearity for the nine organochlorine pesticides was achieved with the determination coefficients (R2) higher than 0.9916. The limits of detection (signal/noise = 3:1) were in the range 0.07–1.03 µg L−1. The recoveries of all analytes for the method at spiked levels of 10 and 100 µg L−1 were 74.9–116.3% and 75.1–112.7%, respectively. The developed M-M-ZIF-67 based magnetic solid-phase extraction method has a potential application prospect for the monitoring of trace level of organochlorine pesticides in environmental water samples.
A Finite Difference Method on Non-Uniform Meshes for Time-Fractional Advection–Diffusion Equations with a Source Term
Authors: Fazio Riccardo , Jannelli Alessandra , Agreste Santa
Published: June 2018

The present paper deals with the numerical solution of time-fractional advection–diffusion equations involving the Caputo derivative with a source term by means of an unconditionally-stable, implicit, finite difference method on non-uniform grids. We use a special non-uniform mesh in order to improve the numerical accuracy of the classical discrete fractional formula for the Caputo derivative. The stability and the convergence of the method are discussed. The error estimates established for a non-uniform grid and a uniform one are reported, to support the theoretical results. Numerical experiments are carried out to demonstrate the effectiveness of the method.
Using the Partial Wave Method for Wave Structure Calculation and the Conceptual Interpretation of Elastodynamic Guided Waves
Authors: Hakoda Christopher , Lissenden Cliff
Published: June 2018

The partial-wave method takes advantage of the Christoffel equation’s generality to represent waves within a waveguide. More specifically, the partial-wave method is well known for its usefulness when calculating dispersion curves for multilayered and/or anisotropic plates. That is, it is a vital component of the transfer-matrix method and the global-matrix method, which are used for dispersion curve calculation. The literature suggests that the method is also exceptionally useful for conceptual interpretation, but gives very few examples or instruction on how this can be done. In this paper, we expand on this topic of conceptual interpretation by addressing Rayleigh waves, Stoneley waves, shear horizontal waves, and Lamb waves. We demonstrate that all of these guided waves can be described using the partial-wave method, which establishes a common foundation on which many elastodynamic guided waves can be compared, translated, and interpreted. For Lamb waves specifically, we identify the characteristics of guided wave modes that have not been formally discussed in the literature. Additionally, we use what is demonstrated in the body of the paper to investigate the leaky characteristics of Lamb waves, which eventually leads to finding a correlation between oblique bulk wave propagation in the waveguide and the transmission amplitude ratios found in the literature.
A Multi-Frame PCA-Based Stereo Audio Coding Method
Authors: Wang Jing , Zhao Xiaohan , Xie Xiang , Kuang Jingming
Published: June 2018

With the increasing demand for high quality audio, stereo audio coding has become more and more important. In this paper, a multi-frame coding method based on Principal Component Analysis (PCA) is proposed for the compression of audio signals, including both mono and stereo signals. The PCA-based method makes the input audio spectral coefficients into eigenvectors of covariance matrices and reduces coding bitrate by grouping such eigenvectors into fewer number of vectors. The multi-frame joint technique makes the PCA-based method more efficient and feasible. This paper also proposes a quantization method that utilizes Pyramid Vector Quantization (PVQ) to quantize the PCA matrices proposed in this paper with few bits. Parametric coding algorithms are also employed with PCA to ensure the high efficiency of the proposed audio codec. Subjective listening tests with Multiple Stimuli with Hidden Reference and Anchor (MUSHRA) have shown that the proposed PCA-based coding method is efficient at processing stereo audio.
A Survey of Regional-Scale Blocking Patterns and Effects on Air Quality in Ontario, Canada
Authors: Dempsey Frank
Published: June 2018

Blocking weather patterns cause persistent weather situations that alter typical wind and circulation patterns which may result in stagnant weather conditions at the surface and potentially adverse conditions that affect society, such as extended warmth, drought, precipitation or fog. One problem that may develop is adverse concentrations of air pollutants in populated regions that may persist for several days or longer. This study looks for possible correlation between blocking patterns and air quality episodes in southern Ontario, Canada. The method used was examination of various cases of air quality episodes. The meteorological details of these examples were examined to determine possible correlations with blocking patterns. Results of the comparisons revealed that various types of blocking patterns correlated with worsening air quality episodes in various regions of southern Ontario. The conclusion is that some large-scale as well as regional-scale blocking patterns may cause adverse air quality in different cities or regions of the province during any month, and forecasters need to be vigilant for these patterns.

Authors: Chu Ya , Gu Lin , Ju Xiuping , Du Hongmei , Zhao Jinsheng , Qu Konggang
Published: June 2018

A composite catalyst was obtained by covalently linking G4-NH2 dendrimers and 1,10-phenanthroline-5-carboxylic acid on the surface of carbon powder, and the composite was named as PMPhen/C. In order to improve the catalytic performance of the composite, copper ions (II) were introduced to PMPhen/C by complex to form the PMPhen-Cu/C catalyst. Scanning electron microscope (SEM) and X-ray photoelectron spectroscopy (XPS) were applied to investigate the surface microstructure and elemental compositions of the catalysts. The results from electrochemical analysis show that PMPhen/C reduced oxygen to hydrogen peroxide (H2O2) through a two-electron transfer process. PMPhen-Cu/C could reduce oxygen to water through a four-electron pathway. Except the slightly lower initial reduction potential, PMPhen-Cu/C has a comparable oxygen reduction ability (ORR) to that of the commercially available Pt/C catalyst, which makes it a potential candidate as the cathodic catalyst in some fuel cells running in neutral medium, such as a microbial fuel cell.

Published: June 2018

The integration of a modular multilevel converter-based high-voltage direct current (MMC-HVDC) transmission system in power networks has led to a high requirement for the rapidity of fault recognition. This study focused on the rapid fault diagnosis of an alternating current (AC) line fault in a back-to-back (BTB) MMC-HVDC system via fault detection and classification. Discrete wavelet transform and modulus maxima were applied to extract the fault features. Phase-mode transformation and normalization were adopted to widen the application range. Simulation and calculation results indicated that the proposed method can detect all fault types in an AC transmission line on the basis of single-side fault information within 1 ms under different values of transition resistance, fault inception angle, and fault distance. The BTB MMC-HVDC model was built using real-time laboratory (RT-LAB) based on the matrix laboratory (MATLAB) software platform, and the fault diagnosis algorithm was performed in MATLAB.
Overexpression of BraLTP2, a Lipid Transfer Protein of Brassica napus, Results in Increased Trichome Density and Altered Concentration of Secondary Metabolites

Published: June 2018

Plant non-specific lipid transfer proteins (nsLTPs) belong to a large multigene family that possesses complex physiological functions. Trichomes are present on the aerial surfaces of most plants and include both glandular secretory hairs and non-glandular hairs. In this study, BraLTP2 was isolated from Brassica rapa (B. rapa) and its function was characterized in the important oilseed crop Brassica napus (B. napus). B. rapa lipid transfer protein 2 (BraLTP2) belongs to the little-known Y class of nsLTPs and encodes a predicted secretory protein. In ProBraLTP2::GUS (β-glucuronidase) transgenic plants, strong GUS activity was observed in young leaves and roots, while low activity was observed in the anther. It is noteworthy that strong GUS activity was observed in trichomes of the first four leaves of 4-week-old and 8-week-old seedings, however, it disappeared in 12-week-old seedings. In transgenic plants expressing a BraLTP2::GFP (green fluorescent protein) fusion protein, GFP fluorescence localized in the extracellular space of epidermal cells and trichomes. Overexpression of BraLTP2 in B. napus caused an increase in trichome number and altered the accumulation of secondary metabolites in leaves, including 43 upregulated secondary metabolites. Moreover, transgenic plants showed significantly increased activities of antioxidant enzymes. These results suggest that BraLTP2, a new nsLTP gene, may play a role in trichome development and the accumulation of secondary metabolites.
Bimodal Function of Anti-TNF Treatment: Shall We Be Concerned about Anti-TNF Treatment in Patients with Rheumatoid Arthritis and Heart Failure?
Authors: Kotyla Przemyslaw J.
Published: June 2018

Treatment with anti-TNF-α (tumor necrosis factor), one of the pivotal cytokines, was introduced to clinical practice at the end of last century and revolutionized the treatment of rheumatoid arthritis (RA) as well as many other inflammatory conditions. Such a treatment may however bring many safety issues regarding infections, tuberculosis, as well as cardiovascular diseases, including heart failure. Given the central role of proinflammatory cytokines in RA, atherosclerosis, and congestive heart failure (CHF), such a treatment might result in better control of the RA process on the one side and improvement of heart function on the other. Unfortunately, at the beginning of this century two randomized controlled trials failed to show any benefit of anti-TNF treatment in patients with heart failure (HF), suggesting direct negative impact of the treatment on morbidity and mortality in HF patients. As a result the anti-TNF treatment is contraindicated in all patients with heart failure and a substantial portion of patients with RA and impaired heart function are not able to benefit from the treatment. The role of TNF in CHF and RA differs substantially with regard to the source and pathophysiological function of the cytokine in both conditions, therefore negative data from CHF studies should be interpreted with caution. At least some of RA patients with heart failure may benefit from anti-TNF treatment, as it results not only in the reduction of inflammation but also contributes significantly to the improvement of cardiac function. The paper addresses the epidemiological data of safety of anti-TNF treatment in RA patients with the special emphasis to basic pathophysiological mechanisms via which TNF may act differently in both diseases.

Tarptautinis olimpinis ir Parolimpinis komitetai nutarė, kad 2012 m. Londone Olimpinės ir Parolimpinės žaidynės vyks tuo pačiu metu. Tyrimo tikslas. Nustatyti, ar Lietuvos neįgalieji sportininkai turi lygias galimybes sportuoti kaip ir negalios neturintys bei integruotis į bendrą Lietuvos sporto sistemą. Sportininkų anoniminė apklausa atlikta 2006 m. Išanalizuotos 235 tyrime dalyvavusių asmenų anketos, iš kurių 159 neįgaliųjų sportininkų, 76 negalios neturintys sportininkai (kontrolinė grupė). Anketas aprobavo ir sutikimą atlikti tyrimą davė Lietuvos parolimpinis komitetas. Apklausa atlikta Lietuvos neįgaliųjų sporto klubuose bei Lietuvos kūno kultūros akademijoje. Tyrimo duomenys apie tiriamųjų nuostatas apie save bei fizinius ir socialinius aplinkos veiksnius rodo, kad visi kontrolinės grupės sportininkų rodikliai buvo statistiškai patikimai (p<0,05) didesni nei neįgaliųjų sportininkų. Daugiau kaip pusė (56,6 proc.) kontrolinės grupės sportininkų pažymėjo, kad jų gyvenimas yra prasmingas, o neįgaliųjų sportininkų – tik 33,8 proc. (p<0,05). 59 proc. kontrolinės grupės sportininkų buvo patenkinti gyvenimo kokybe, o neįgaliųjų sportininkų gerokai mažiau – 36,2 proc. Tuo tarpu 56,6 proc. kontrolinės grupės sportininkų pažymėjo, kad sportas jų gyvenime yra svarbus, o neįgaliųjų sportininkų rodiklis buvo žymiai mažesnis – 33,2 proc. Tik pusė (51,6 proc.) tyrime dalyvavusių neįgaliųjų sportininkų turi nuolatinį trenerį. Absoliuti dauguma tyrime dalyvavusių sportininkų (nepriklausomai nuo įgalumo) pažymėjo, kad sportas padeda jiems realizuoti save. Mūsų duomenimis, dauguma kontrolinės grupės (74,6 proc.) ir absoliuti dauguma neįgaliųjų sportininkų (92,5 proc.) pažymėjo, kad žiniasklaidoje neįgaliųjų sportas nepakankamai propaguojamas. Nepakankamas informacijos kiekis apie neįgaliųjų sportą, asmenybės, fizinių bei socialinių aplinkos veiksnių rodikliai žemesni nei kontrolinės grupės sportininkų yra esminė kliūtis neįgaliųjų savarankiškos socialinės sporto sistemos kūrimui bei integracijai į bendrąją Lietuvos sporto sistemą lygių galimybių aspektu.

Nustatyti kepenų rezekcinių operacijų metu vykstančių hemodinaminių pokyčių priežastis bei jų pobūdį, kai nenaudojamos kepenų kraujotakos sustabdymo metodikos, bei parinkti labiausiai tinkamus paciento stebėsenos metodus. Metodai. Į prospektyvųjį tyrimą įtraukti 55 pacientai, kuriems 2003–2008 m. Lietuvos sveikatos mokslų universiteto ligoninės Kauno klinikose (tuometinėse KMUK) Chirurgijos klinikoje buvo atliktos kepenų rezekcinės operacijos. Papildomai buvo stebimi pacientų centrinės hemodinamikos rodmenys, arterinis kraujo spaudimas, centrinis veninis spaudimas ir slėgis apatinėje tuščiojoje venoje invaziniais metodais. Rezultatai. 53 pacientams operacijos metu konstatuoti hipotenzijos epizodai (iš viso 186) – 3,4 (2,0) vienam pacientui. Slėgio šlaunies venoje pokyčiai, nustatyti 54 pacientams (iš viso 262) – 4,8 (3,2) vienam pacientui. Hipotenzijos epizodo metu reikšmingai kito, atsižvelgiant į pradines reikšmes, slėgis šlaunies venoje, širdies minutinis tūris, širdies indeksas, sisteminis periferinių kraujagyslių priešinimosi indeksas, centrinis veninis slėgis. Netekto kraujo kiekis ir slėgio šlaunies venoje pokyčių skaičius tarpusavyje koreliavo teigiamai reikšmingai (r=0,5; p<0,001). Daugiau kaip 450 ml kraujo neteko 69,0 proc., jei centrinis veninis spaudimas didėjo, 38,3 proc., jei jis mažėjo (p<0,01). Daugiau kaip 450 ml kraujo neteko 41,6 proc. neigiamo slėgio šlaunies venoje pokyčio grupėje, 88,0 proc. – teigiamo pokyčio grupėje (p<0,001). Išvados. Kepenų operacijų metu dažniausiai stebimi hemodinaminiai pokyčiai yra hipotenzija, širdies indekso sumažėjimas ir slėgio apatinėje tuščiojoje venoje padidėjimas. Hipotenzijos priežastis dažniau yra apatinės tuščiosios venos perspaudimas, rečiau – kraujo netekimas. Kraujo netekimas susijęs su apatinės tuščiosios venos perspaudimų skaičiumi ir su didėjančiu slėgiu viršutinėje tuščiojoje venoje. Hipotenzijos priežastį kepenų rezekcinių operacijų metu galima nustatyti stebint slėgius viršutinėje bei apatinėje tuščiojoje venoje.

Published: June 2018

Osteoporosis and periodontal diseases are common problems among the elderly population. Vitamin D is a secosteroid hormone that is either synthesized by human skin cells under the effect of UV radiation or consumed through diet. Deficiency in vitamin D leads to reduced bone mineral density, osteoporosis, the progression of periodontal diseases and causes resorption to occur in the jawbone. Sufficient intake of vitamin D can decrease the risk of gingivitis and chronic periodontitis, as it has been shown to have immunomodulatory, anti-inflammatory, antiproliferative effects and initiates cell apoptosis. In addition, vitamin D is also important for bone metabolism, alveolar bone resorption and preventing tooth loss. It increases antibacterial defense of gingival epithelial cells and decrease gingival inflammation, improves postoperative wound healing after periodontal surgery and is an important supplement used as prophylaxis in periodontology. This publication aims to update the recent advances, stress the clinical importance, and evaluate vitamin D in the prevention of periodontal diseases to reach a successful outcome of conservative and surgical treatment. An analysis of the literature shows that vitamin D plays a significant role in maintaining healthy periodontal and jaw bone tissues, alleviating inflammation processes, stimulating post-operative healing of periodontal tissues and the recovery of clinical parameters. However, further research is needed to clarify the required vitamin D concentration in plasma before starting periodontal treatment to achieve the best outcome.

We describe the syntheses of nine new angucyclinone 6-aza-analogues, achieved through a hetero Diels-Alder reaction between the shikimic acid derivative-azadiene 13, with different naphthoquinones. The cytotoxic activity of the new synthesized compounds and five angucyclinones, previously reported, was evaluated in vitro against three cancer cell lines: PC-3 (prostate cancer), HT-29 (colon cancer), MCF-7 (breast cancer), and one non-tumoral cell line, human colon epithelial cells (CCD841 CoN). Our results showed that most 6-azadiene derivatives exhibited significant cytotoxic activities, which was demonstrated by their IC50 values (less than 10 μM), especially for the most sensitive cells, PC-3 and HT-29. From a chemical point of view, depending on the protected group of ring A and the pattern of substitution on ring D, cytotoxicity elicited these compounds, in terms of their potency and selectivity. Therefore, according to these chemical features, the most promising agents for every cancer cell line were 7a, 17, and 19c for PC-3 cells; 7a, 17, and 20 for HT-29 cells, and 19a for MCF-7 cells.

Published: June 2018

The increased interest in natural cosmetics has resulted in a higher market demand for preservative-free products based on herbal ingredients. An innovative W/O/W type emulsions containing herbal extracts were prepared directly; its cation form was induced by an ethanolic rosemary extract and stabilized using weak herbal gels. Due to the wide phytochemical composition of herbal extracts and the presence of alcohol in the emulsion system, which can cause skin irritation, sensitization or dryness when applied topically, the safety of the investigated drug delivery system is necessary. The aim of our study was to estimate the potential of W/O/W emulsions based on natural ingredients for skin irritation and phototoxicity using reconstructed 3D epidermis models in vitro and to evaluate in vivo its effect on human skin moisture, sebum content and pigmentation by biomedical examination using a dermatoscopic camera and corneometer. According to the results obtained after in vitro cell viability test the investigated emulsion was neither irritant nor phototoxic to human skin keratinocytes. W/O/W emulsion did not cause skin dryness in vivo, despite the fact that it contained ethanol. We can conclude that the emulsion is safe for use as a leave-on product due to the positive effect on human skin characteristics or as a semisolid pharmaceutical base where active compounds could be encapsulated.
Two-Phase Framework for Indoor Positioning Systems Using Visible Light †
Authors: Prince Gregary B. , Little Thomas D. C.
Published: June 2018

Recently with the advancement of solid state lighting and the application thereof to Visible Light Communications (VLC), the concept of Visible Light Positioning (VLP) has been targeted as a very attractive indoor positioning system (IPS) due to its ubiquity, directionality, spatial reuse, and relatively high modulation bandwidth. IPSs, in general, have four major components: (1) a modulation, (2) a multiple access scheme, (3) a channel measurement, and (4) a positioning algorithm. A number of VLP approaches have been proposed in the literature and primarily focus on a fixed combination of these elements and moreover evaluate the quality of the contribution often by accuracy or precision alone. In this article, we provide a novel two-phase indoor positioning algorithmic framework that is able to increase robustness when subject to insufficient anchor luminaries and also incorporate any combination of the four major IPS components.
Microaggressions Self-Defense: A Role-Playing Workshop for Responding to Microaggressions
Authors: Byrd Christy M.
Published: June 2018

Microaggressions are subtle verbal and non-verbal slights based on group membership, and they are ubiquitous in the lives of racial minorities, women, and LGBTQ individuals. The goal of the current paper is to introduce a role-playing based exercise on effective responses to microaggressions. The workshop draws on two previous prejudice responding workshops but integrates research-based strategies.

Published: June 2018

A pot experiment was conducted to evaluate the effect of Na2-EDTA 0.01 M (E) and olive mill wastewater 15% (OMW) on As, Pb, and Zn uptake by Pteris vittata L. grown in a soil highly contaminated by mining activities. A two-factor experimental design was followed; 3 treatments (E, OMW, and E + OMW) × 2 batches (single or double dose). Six weeks after the P. vittata transplanting, all pots received the selected dose of each treatment (Batch I). At 8 weeks, in half of the pots, a second dose of the same treatments was added (Batch II). Plants were harvested after 10 weeks and As, Pb, and Zn concentrations were determined in fronds and roots. Depending on the element, both treatment and batch effects were significant. In Batch II, EDTA application resulted in a 55% increase of As and 9- and 4-fold of Pb and Zn concentrations in the fronds, while OMW treatment substantially reinforced plant uptake when combined with EDTA. Roots to fronds translocation of the metal(loid)s highly increased in Batch II. After harvest, composite soil samples of all treatment–batch combinations were subjected to sequential extraction, but no significant differentiations of As, Pb, and Zn partitioning in soil phases were detected.
The Effect of Sustainability as Innovation Objectives on Innovation Efficiency

Published: June 2018

Though sustainability exists as major objective of pursuing innovation, the effect of it on innovation performance is still unanswered. While the outcome of innovation should consider both input and output, moreover, studies on sustainable innovation are yet to consider the overall efficiency, but rather the performance itself. To fill the gap between the effect of sustainability as the objective of innovation and its innovation performance, and to bridge the hole between the outcome of sustainable innovation and its efficiency, we analyze the relationship between sustainability as innovation objective and innovation efficiency. We use 441 manufacturing companies in Korea from 2016 KIS data, and perform the data envelopment analysis (DEA) method to calculate efficiency score of each firm and tobit regression analysis to investigate the effect of sustainability as an objective of innovation on innovation efficiency. The results show that the objective of ‘environmental improvement’ negatively affects innovation efficiency, while ‘safety improvement’ positively affects the efficiency. On the contrary, the effect of ‘material and energy reduction’ as an objective of innovation on innovation efficiency is not verified. The implications, limitations, and guidelines for future research are presented.
Replacing Self-Efficacy in Physical Activity: Unconscious Intervention of the AR Game, Pokémon GO
Authors: Kim Hana , Lee Hyung Jin , Cho Hosoo , Kim Eungdo , Hwang Junseok
Published: June 2018

With increases in aging and chronic disease, there have been efforts to apply IT to healthcare. Many studies show that the will to exercise (self-efficacy) is the most important factor contributing to physical activity. However, those who need exercise do not have this will so that an approach to increase the motivation for physical activity should be unconscious. Thus, playing Pokémon GO, an augmented reality (AR) mobile game requiring players to ambulate in reality, increases the physical activity of individuals with a simple motivation of enjoyment. A survey on 237 Pokémon GO players was analyzed using structural equation modeling (SEM) considering libertarian paternalism. The results show that self-efficacy had a non-significant effect on attitude toward the game Pokémon GO, while previous studies found that self-efficacy is the most important factor in increasing physical activity. This indicates that playing AR drives physical activity, subconsciously and effectively.
