Development of a Computerized-Adaptive Test to Measure English Vocabulary Size with IRT

To speak English fluently like a native speaker, having a vocabulary of 20,000 words are required. In many universities in Indonesia, Vocabulary Size Test (VST) is still held with Paper-Based Test (PBT), so it is less effective and efficient. The aims of this study were 1) to develop Computerized-Adaptive Testing (CAT), which helps get students with a standardized English vocabulary size, and 2) to implement it in measuring vocabulary size. The approach in this study is Research and Development (RD) with product development procedures following the steps of Borg and Gall. The findings of this study are, 1) the CAT program has Item Response Theory (IRT) parameters that can change according to the test takers' answers, and the test will stop if the estimated ability of the test takers is known (Standard Error/SE close to 0.01), and 2) with the application of the CAT program it can be seen that the total vocabulary of English Language and Teaching Department students is still 20,000. Based on these findings, this study implies that for students' vocabulary mastery to be on par with native speakers' abilities, the English Language and Teaching Department needs to evaluate the learning process and determine a particular program to increase student vocabulary.

Interactive Multimedia Based Long Jump Athletic Learning During the Covid-19 Pandemic at FIK UNIMED

Jump numbers are included in the classification of skill types that are acycliccombined. This means that there is a cyclic movement which is then continued with the acyclical movement so that it can take advantage of the part method (partmethod) and the whole (whole method). It provides an understanding of audio as something related to reception through sound and hearing. Visual is something related to the eye or vision, props, can be seen and witnessed. It can be said that audio visuals are "something related to reception through hearing and sight, sound and props, audible and witnessable". In this case, audio visual media is used to record the initial ability of students by analyzing movements using kinovea applications so that specific movement hasis are obtained. The use of audio visual media to evaluate the series of long jump movements can be one alternative in determining learning variations that are in accordance with the ability of students. The methods used in this study use development research. Research in this learning model uses quantitative approaches as well as using the Research & Development (R&D) development model of Borg and Gall. The product development procedure can be described as follows: a) Determination of ideas, b) Model making, c) Evaluation.The subject used in the athletics course of the Long Jump branch in FIK UNIMED students is qualitative data, because it is expressed by sentences and not numbers, while the quantitative data is obtained by converting qualitative data by giving a score to the data that has been collected.

Digital Twin Bionics: A Biological Evolution-Based Digital Twin Approach for Rapid Product Development

With intensified market competition, product development procedure is accelerated, requiring rapid product innovation and efficient collaboration between design and manufacturing. However, there still exist information islands, prohibiting integration of product life cycle processes. To address this issue, bionics and digital twin (DT) are combined as a potential solution. The concepts, framework, and features of digital twin bionics (DTB) is originally proposed, with co-evolution mechanism of product-twins (including virtual and physical products) and production-twins (including virtual and physical production) elaborated. A symbiotic co-evolution mechanism is presented to integrate the processes of product development and manufacturing. In detail, the supporting technologies, such as industrial internet of things, cloud edge computing, big data, and artificial intelligence, as well as the potential key technologies, are illustrated. A case study for rapid development of automotive body-in-white in an industrial robotics welding production line is investigated to verify the applicability of the proposed framework. The results suggest that the integration of bionics and DTs can accelerate the innovations and developments of new products and management the process of production construction.

Global Marketing Strategic Approaches on Multi National Companies Product Development

When it comes to business prospects, all organizations try to implement effective marketing mix strategies to ensure consistent operations. While these strategic approaches help a business sustain product development procedures, it also inflicts a humongous impact on issues concerning product development and promotion. In terms of global marketing, most multinational companies and retail firms aim to implement sustainable marketing mix strategies to build and expand their products or services to grab a considerable portion of foreign market share. This not only helps them to generate the desired revenues but also helps a business to enhance its customer base in the target market. This in turn escalates the eminence of the organizational reputation in the host market. However, this paper aims to examine the implications of marketing mix strategies on the product development issues in MNCs and/or retail industries. Through extensive literature mining from previous studies, this paper focuses on analyzing the effect of the strategic approaches used by most marketing experts to mediate the issues of product development. It intends to explore and cast light on the judicious role of the marketing mix in obtaining a competitive edge in most MNCs/retail firms. In the process, it also covers the relationship between the four basic components of the marketing mix, the 4Ps. The paper highlights how the marketing mix can influence the intricacies pertaining to the development process of a product. The study has the potential to provide managers with manual assistance on how these marketing strategies should be implemented and expanded to ameliorate business performance.

Physical simulation technology for thermo-mechanical processing of metallic alloys using Gleeble system

Thermo-mechanical processing has indicated a major obligation for increasing the strength and other mechanical properties of metallic alloys. Different kinds of thermo-mechanical processing could be marked depending on the stage in the heat treatment cycle where deformation is to be introduced.Product development includes the design of the alloy chemistry and process parameters involved in heat-treatment, hot rolling, annealing, post-cooling, continuous casting, … etc. Any change in the process parameters or alloy chemistry requires a thorough understanding of materials’ behavior. Experimental trials, if carried out on plant scale will be highly costing and time-consuming. Sometimes, it is even impossible. This leads to a so prolonged procedure for product development making it unprofitable or even techno-economically infeasible. However, a significant improvement could be achieved, by using a Thermo-mechanical Simulator to optimize the process parameters before attaining the manufacturing level. Moreover, it also assists to investigate materials’ attitude under different processing conditions, prompting to quality improvement of the existent products and dealing with materials deficiency problems, which in return, leads to yield improvement. For an economical production of optimized mechanical components, it is necessary to describe the metal forming processes by means of numerical process simulation, as well as structure modeling close to reality. A meaningful extension is the description of the formability of the material with concepts of the mechanic of damage and the exact determination of the system work-piece tool. Laboratory experiments and structural analysis of the formed samples are to be accomplished with the thermo-mechanical forming modem, as well as analysis facilities in order to evaluate the chosen models. Rotational forging, multistage hot rolling … etc. are examples of metal plastic deformation processes, where massive amounts of strain are attained. To supply physical simulation of such processes, a new tension-compression technique for Gleeble Systems was developed.In this article, Thermo-mechanical processing of some different alloys using Gleeble systems as a physical simulation technique is described and compared.
