Although the use of Grammatical Metaphor (GM) has been regarded as one of the representative features of academic writing in the framework of Systemic Functional Linguistics (SFL), not many studies have explored its role in second or foreign language writers’ writing quality. This study aimed to discover the potential relationship between GM development and argumentative writing quality of advanced Korean EFL learners, while controlling for their overall language proficiency and reading comprehension ability. The findings from this study unveiled significant contribution of the use of both premature and mature GM and also identified transcategorization as the specific GM that has relatively stronger predictability of writing quality. The results from current research yield meaningful pedagogical implications for writing instruction in Korean EFL contexts.

To develop flexible adsorbents for compact volatile organic compound (VOC) air purifiers, flexible as-spun zeolite fibers are prepared by an electrospinning method, and then zeolite particles are exposed as active sites for VOC (toluene) adsorption on the surface of the fibers by a thermal surface partial etching process. The breakthrough curves for the adsorption and temperature programmed desorption (TPD) curves of toluene over the flexible zeolite fibers is investigated as a function of the thermal etching temperature by gas chromatography (GC), and the adsorption/desorption characteristics improves with an increase in the thermal surface etching temperature. The effect of acidity on the flexible zeolite fibers for the removal of toluene is investigated as a function of the SiO2/Al2O3 ratios of zeolites. The acidity of the flexible zeolite fibers with different SiO2/Al2O3 ratios is measured by ammonia-temperature-programmed desorption (NH3-TPD), and the adsorption/desorption characteristics are investigated by GC. The results of the toluene adsorption/desorption experiments confirm that a higher SiO2/ Al2O3 ratio of the flexible zeolite fibers creates a better toluene adsorption/desorption performance.

The present study aimed to investigate rapid weight loss (RWL) and consequent physical and psychological challenges among judo athletes at the national athlete training center in 2017. The following results were obtained. Judo athletes used weight loss methods such as “gradually reduce meal portion,” “skip meals,” “limit water intake,” “wear sweat suit for training,” and “use sauna,” and had physical and mental distress from such unhealthy weight management practices. Information about weight loss was obtained from “colleagues or senior athletes,” “Internet,” and “head coach or coach,” and not experts such as nutritionists or physicians. Thus, athletes are recommended to employ healthy weight control methods based on advice from experts, such as nutritionists and physicians

The purpose of this study was to assess the changes in balance and proprioception of adults with limited ankle joint dorsiflexion, after the application of talocrural joint mobilization. The subjects of this study included 23 college students in their twenties with limited ankle joint dorsiflexion. The students were randomly assigned to the ankle joint mobilization group (AJMG, n=12) and the control group (CG, n=11). After 2 weeks of intervention using grade III talocrural joint mobilization in the anterior-posterior movement, the balance and proprioception of the subjects were assessed. Static/dynamic balance capabilities and ankle proprioception were analyzed using paired t-test and independent t-test. The dynamic balance and proprioception of AJMG were significantly improved after intervention (p<.05), In the comparison between the groups after the intervention, the dynamic balance and proprioceptive sense of AJMG were significantly improved compared to the control group (p<.05). This study suggests that AJMG can help improve the dynamic balance and proprioception.

The hand held voltammetry systems searched diabetic assay using glucose sensor of fluorine nafion doped carbon nanotube electrode (FCNE). An inexpensive graphite carbon pencil was used as an Ag/AgCl reference and Pt counter electrode. Upon combining and using three electrode systems, optimum square wave (SW) stripping results were attained to 1.0-9.0 ug/L with 8 points. Statistic RSD precision was of 6.02 % with n=15 in 0.1 mg/L glucose. After a total of 200 second accumulation times, analytical detection limit of 0.8 ug/L was obtained. This developed technique was applied to urine samples from diabetic patients urine for fluid analysis, it was determined that the sensor can be used with a diagnostics in the ex vivo of live cells and non treated biological fluid.

The purpose of this study was to assess cross-generational effects of bisphenol A exposure in benthic copepods, Tigriopus west. Nauplii (<24 hours old) were exposed to graded concentrations of bisphenol A, and toxicity end-points such as survival, development, sex ratio, and fecundity were measured. F1 generations were grown under innoxious conditions, and similarly assessed. Significant differences were observed in development of nauplii and copepodites, between exposed and non-exposed copepods; however, there were no differences in survival of nauplii or copepodites, sex ratio, or brooding rate in parental generation. In contrast, in the F1 generation, there were significant differences between the control group and exposed group in survival and development of nauplii. Length, width, and biomass of parental and F1 generations were reduced in the exposed group compared to the control group. In addition, some deformities, such as swelling of the prosome, abnormally shaped egg sac, and dwarfism were observed after exposure to bisphenol A. So, our study demonstrates that a cross-generation toxicity test and monitoring of morphological deformities in harpacticoid copepods, can be useful for development of potential bioindicators for environmental monitoring, and assessment of chemical impact.

Performance-based seismic evaluation is usually done by considering simplified models for the liquid storage tanks therefore, it is important to validate those simplified models before conducting such evaluation. The purpose of this study is to compare the seismic response results of the FSI (fluid-structure interaction) model and the simplified models for the cylindrical liquid storage tanks and to verify the applicability of the simplified models for estimating failure probability. Seismic analyses were carried out for two types of storage tanks with different aspect ratios (H/D) of 0.45 and 0.86. FSI model represents detailed 3D fluid-structure interaction model and simplified models are modeled as cantilever mass-spring model, frame type mass-spring model and shell type mass-spring model, considering impulsive and convective components. Seismic analyses were performed with modal analysis followed by time history analysis. Analysis results from all the models were verified by comparing with the results calculated by the code and literature. The results from simplified models show good agreement with the ones from detailed FSI model and calculated results from code and literature, confirming that all three types of simplified models are very valid for conducting failure probability analysis of the cylindrical liquid storage tanks.
