The Effects of Learner Autonomy on Writing in EFL
Am anda Sheffield(Am anda Sheffield ) 글로벌응용인문학회 2023 글로벌응용인문학연구 Vol.1 No.2
The purpose of this study was to investigate whether and to what extent autonomic and non-autonomous variables affect students' intrinsic motivation and satisfaction with these activities. Students’ academic performance in English as a Foreign Language (EFL) writing classes was examined to uncover any potential connections between learner autonomy (LA) and academic performance. An analysis of statistical significance was performed using a paired sample t-test on the resultant pairs of student perceptions. Based on the results of this study, the perception of autonomous activities among students is positive. Additionally, they performed better in such EFL writing contexts because of their autonomous activities. Based on the results of the present study, instructors should incorporate autonomous activities into the teaching process in EFL writing classes. EFL writing classrooms may provide students with the opportunity to play a more active role than a passive one, with the ability to effectively contribute to developing syllabuses and curriculum, which can increase their intrinsic motivation and improve their academic performance. As a result, students are motivated to take responsibility for their actions.

Hepatocellular carcinoma (HCC) is a primary liver cancer with high global incidence and mortality rates. Current candidate drugs to treat HCC remain lacking and those in use possess undesirable side effects. In this investigation, the antiproliferative effects of dentatin (DTN), a natural coumarin, were evaluated on HepG2 cells and DTN's probable preliminary molecular mechanisms in apoptosis induction were further investigated. DTN significantly (p<0.05) suppressed proliferation of HepG2 cells with an $IC_{50}$ value of $12.0{\mu}g/mL$, without affecting human normal liver cells, WRL-68 ($IC_{50}$ > $50{\mu}g/mL$) causing $G_0/G_1$ cell cycle arrest via apoptosis induction. Caspase colorimetric assays showed markedly increased levels of caspase-3 and caspase-9 activities throughout the treatment period. Western blotting of treated HepG2 cells revealed inhibition of $NF-{\kappa}B$ that triggers the mitochondrial-mediated apoptotic signaling pathway by up-regulating cytoplasmic cytochrome c and Bax, and down-regulating Bcl-2 and Bcl-xL. The current findings suggest DTN has the potential to be developed further as an anticancer compound targeting human HCC.
On the minimal graded free resolution of powers of lexsegment ideals
Anda Olteanu 대한수학회 2013 대한수학회지 Vol.50 No.3
We consider powers of lexsegment ideals with a linear resolu-tion (equivalently, with linear quotients) which are not completely lexseg-ment ideals. We give a complete description of their minimal graded freeresolution.

Transport modelling in the age of big data

New Big Data sources such as mobile phone call data records, smart card data and geo-coded social media records allow to observe and understand mobility behaviour on an unprecedented level of detail. Despite the availability of such new Big Data sources, transport demand models used in planning practice still, almost exclusively, are based on conventional data such as travel diary surveys and population census. This literature review brings together recent advances in harnessing Big Data sources to understand travel behaviour and inform travel demand models that allow transport planners to compute what-if scenarios. From trip identification to activity inference, we review and analyse the existing data-mining methods that enable these opportunistically collected mobility traces inform transport demand models. We identify that future research should tap on the potential of probabilistic models and machine learning techniques as commonly used in data science. Those data-mining approaches are designed to handle the uncertainty of sparse and noisy data as it is the case for mobility traces derived from mobile phone data. In addition, they are suitable to integrate different related data sets in a data fusion scheme so as to enrich Big Data with information from travel diaries. In any case, we also acknowledge that sophisticated modelling knowledge has developed in the domain of transport planning and therefore we strongly advise that still, domain expert knowledge should build the fundament when applying data-driven approaches in transport planning. These new challenges call for a multidisciplinary collaboration between transport modellers and data scientists.

<P>A novel beam emission spectroscopy observation system was designed, built, and installed onto the Korea Superconducting Tokamak Advanced Research tokamak. The system is designed in a way to be capable of measuring beam emission either from a heating deuterium or from a diagnostic lithium beam. The two beams have somewhat complementary capabilities: edge density profile and turbulence measurement with the lithium beam and two dimensional turbulence measurement with the heating beam. Two detectors can be used in parallel: a CMOS camera provides overview of the scene and lithium beam light intensity distribution at maximum few hundred Hz frame rate, while a 4 ?? 16 pixel avalanche photo-diode (APD) camera gives 500 kHz bandwidth data from a 4 cm ?? 16 cm region. The optics use direct imaging through lenses and mirrors from the observation window to the detectors, thus avoid the use of costly and inflexible fiber guides. Remotely controlled mechanisms allow adjustment of the APD camera's measurement location on a shot-to-shot basis, while temperature stabilized filter holders provide selection of either the Doppler shifted deuterium alpha or lithium resonance line. The capabilities of the system are illustrated by measurements of basic plasma turbulence properties.</P>

A 54-years-old man with history of acute pancreatitis 4 years before and secondary DM, he also had history of primary hypothyroidism and hypertension. He was admitted in hospital in 2010 with sudden and bilateral hearing loss, headache and dizziness. Neuro-otological examination revealed a sensorineural hearing loss (SNHL) and he was given Dexamethasone trans-tympanic, then he was treated with Ganciclovir (12 mg/kg/24 h) for 10 days + prednisone 50 mg/24 h for 4 weeks. At the end, pure tone audiometry confi rmed a SNHL affecting both ears. aCL antibodies were positives and he was send to internal medicine consultation. The diagnosis of microangiopathic antiphospholipid sindrome (MAPS) on the basis of presumed thrombotic cause of SNHL was made and he was formally anticoagulated with warfarin. He has had no additional thrombotic episodes, although SNHL prevails. Full blood count, serum electrolytes, renal function, urinalysis and cerebrospinal fi uid analysis were normal. Coagulation: PT 53. 1”, aPTT 92. 6”, Lupus anticoagulant: 1. 69 (positive<1. 2). Anti-ß2 Gp1 IgM:3350 (negative<8 U/ml), Anti-ß2 Gp1 IgG: 6. 8 (negative<14. 3 U/ml), aCL IgM: >255 (negative<15), aCL IgG: 46. 3 (negative<20). ANAs, Anti-dsDNA, Anti-Sm were negative. MRI of brain on T2 weighted showed white matter hyperintensities and subcortical hyperintensities in frontal and parietal lobes, meaning microangiopathic injury on brain parenchymal. Conclusion: MAPS is a subset of Antiphospholipid Syndrome which occlusive thrombosis of small blood vessels and microangiophaty dominate the clinical picture. Several neurological disorders have been described in association with antiphospholipid antibodies (aPL) without thrombosis of large-vessels like Myelitis Transverse, Multiple Sclerosis-like Disease, Dementia, Chorea, Migraine and Epilepsy. SNHL is a rare syndromethat leads rapidly progressive bilateral hearing loss, and it has been strongly associated with aPL. There are a few cases in medical literature and there is no consensus about appropriate treatment but anticoagulation is widely accepted.
