Penguasaan kemampuan berbahasa Inggris menjadi kebutuhan masyarakat, khususnya dalam pendidikan. Untuk mengukur kemahiran diperlukan tes berstandar internasional yang disebut dengan Test of English Proficiency (TOEP) atau as a Foreign Language (TOEFL). Oleh karena itu, pendampingan persiapan Tes TOEFL sejak level sekolah menengah. Kegiatan dilaksanakan pengabdian ini adalah memberikan pelatihan...

The principles and practices that guide the design and development of test items are changing because our assessment practices are changing. Educational visionary Randy Bennett (2001) anticipated that computers and the Internet would become two of the most powerful forces of change in educational measurement. Bennett’s premonition was spot-on. Internet-based computerized testing has dramaticall...

This report shows methods to fabricate polydimethylsiloxane (PDMS) microfluidic systems for longterm (up to 10 day) cell culture. Undesired bubble accumulation in microfluidic channels abruptly changes the microenvironment of adherent cells and leads to the damage and death of cells. Existing bubble trapping approaches have drawbacks such as the need to pause fluid flow, requirement for externa...

Chikungunya virus (CHIKV) infection is one of the most challenging human Arboviral infections with global significance and without any specific antiviral. In this investigation, 1-[(2-methylbenzimidazol-1-yl) methyl]-2-oxo-indolin-3-ylidene] amino] thiourea (MBZM-N-IBT) was synthesised as a molecular hybrid of 2-methyl benzimidazole and isatin-β-thiosemicarbazone and its anti-CHIKV property was...

We compared the effects of three treatment approaches on preschool-age children with autism spectrum disorders. Twenty-nine children received intensive behavior analytic intervention (IBT; 1:1 adult:child ratio, 25-40 h per week). A comparison group (n=16) received intensive "eclectic" intervention (a combination of methods, 1:1 or 1:2 ratio, 30 h per week) in public special education classroom...

OBJECTIVE The aim of this study was to assess the actual effectiveness of long-term phlebotomy by comparing histological improvement (HI) in 69 Caucasian HCV-RNA-positive CHC patients undergoing phlebotomy or receiving an interferon-based therapy without virological response [nonresponders to interferon therapy(IBT-NR)]. METHODS HI was defined by at least one point reduction of the staging sc...

This paper introduces a method for the semi-automatic generation of grammar test items by applying Natural Language Processing (NLP) techniques. Based on manually-designed patterns, sentences gathered from the Web are transformed into tests on grammaticality. The method involves representing test writing knowledge as test patterns, acquiring authentic sentences on the Web, and applying generati...

Beak trimming is necessary in commercial broiler breeders to prevent or decrease trauma as they mature. Two common beak-trimming methods were evaluated by early performance comparison with nontrimmed chicks (NBT). The robotic electrocautery device (ECD) trims and cauterizes the beak tip. The robotic infrared beak-trimming device (IBT) applies an infrared light beam to destroy the live basal tis...

the interaction between isatin-β-thiosemicarbazone (ibt) and calf thymus dna (ct-dna) was investigated in physiological buffer (ph 7.4) using neutral red (nr) dye as a spectral probe by uv–vis absorption and fluorescence spectroscopy, as well as viscosity measurements. the ibt is stabilized by intercalation in the dna ( k [ibt –dna] =1.03×105 m−1), and displaces the nr dye from the nr–dna comple...

In this study, I examine several different approaches to identifying entities and relations in sentences. I compare three different strategies to learn entities and relations. The first uses just local classifiers, the second uses local classifiers with integer linear programming (ILP) inference, and the third uses inference based training (IBT) and evaluates using ILP inference. My experiments...
