Developing a Web-Based Vocabulary Size Test for Indonesian EFL Learners
Authors: Endarto Ignatius Tri , Subekti Adaninggar Septi
Published: February 2021

One important aspect of English language learning is vocabulary. However, the availability of vocabulary proficiency tests, both manual and computer-based, is still limited. Almost all currently existing vocabulary tests are monolingual and have not accommodated the needs of EFL learners. The objective of this study was to develop a web-based vocabulary size test for English learners in Indonesia. It consisted of 6 stages, namely: (1) needs analysis; (2) corpus selection and corpus data analysis; (3) sampling to select words from corpus data; (4) generating test items; (5) developing a web-based version of the test and pilot study; and (6) reflection and evaluation. Pilot study involved having a sample group of English learners in Indonesia try out the designed vocabulary size test. A paired-samples t-test was then used to determine whether there was a significant difference between the learners’ scores on the designed test and those on a free online vocabulary size test not specifically designed for Indonesian test takers. The t-test indicated that there was a significant difference between the designed test scores (M=6433, SD=1169) and free online test scores (M=5700, SD=1616); t(35)=-3.597, p = 0.001. The identifiable factors which seemed to contribute to this difference were different corpus data (COCA vs. BNC), different varieties of English (American vs. British), and different formats (bilingual vs. monolingual). Despite the difference, there was a positive correlation between the two tests (Correlation = 0.657) meaning that higher scores on one of the tests equals higher scores on the other.

Authors: Kuswoyo Heri , Audina Ayu Yeza
Published: February 2021

This study was an attempt to investigate the consecutive interpreting strategies used by an Indonesian interpreter, Yuliana Tansil, in the court setting. This study examined a trial court in English and consecutively interpreted it to Indonesian. Faerch and Kasper’s (1983) theory of consecutive interpreting strategy was used. The descriptive qualitative method was applied as the method of this study. Data were collected through video recording taken from official YouTube. The video then was transcribed carefully. The results showed that the interpreter used two types of consecutive interpreting strategies, namely reduction strategies, and achievement strategies. In terms of reduction strategy, the interpreter applied skipping, incomplete sentence, and filtering. Yet, the message abandonment was not found in this study. In terms of achievement strategies, the interpreter used both appeal for assistance and elaborate strategy. The results also indicated that the interpreter frequently elaborated and expanded the lexical meaning of words or phrases in the utterances. The interpreter used this strategy when she faced the difficult words in long utterances because of some cultural nuance. So, she elaborated on her understanding of the message by adding more information as a way of making the utterance in the target language to be understood better.

Authors: Rido Akhyar , Kuswoyo Heri , Suryaningsih Ayu Sumarni , Nuansa Sandi , Ayu Ramelia , Arivia Rama Putra
Published: February 2021

This study was an attempt to investigate types and functions of repair strategies used by lecturers in English literature lectures in a university in Indonesia. Rido’s conceptual framework of repair strategies (2018) was used. Qualitative method was applied while the data were collected through video recording of three English literature lectures, comprising prose, drama, and literary criticism. The findings showed that the lecturers repaired both the linguistic (grammatical and pronunciation errors) and content-related aspects of the students while they were giving oral responses and making presentations. Therefore, the lecturers employed four types of repair strategies such as indicating an error has been made and correcting it, asking students to make self-repairs, indicating an error has been made and getting other students to correct it, and repeating students’ responses with changes. The functions of those repair strategies were to show the lecturers as role model and reliable source of knowledge, to give good examples, to make students think critically, to give opportunity for students to share ideas, and make students not aware they were being corrected so that they kept learning. The findings offer some implications for pedagogical considerations within university lecture, especially in English as a foreign language (EFL) setting.

Published: February 2021

Objective: Minor salivary gland biopsy is an adjunctive diagnostic method which is widely used and its diagnostic value is still controversial. It is mainly used in sarcoidosis and Sjögren’s Syndrome. This study aims to identify the contribution of histopathological diagnosis to clinical diagnosis and to supply information to literature.
Methods: Minor salivary gland biopsy was carried out on the patients with early diagnosis of sarcoidosis or Sjögren’s Syndrome who were referred from the hospital clinics of Istanbul University Faculty of Medicine, to the Oral and Maxillofacial Surgery Department of the Faculty of Dentistry. 100 patients between the ages of 18-65 were performed lower lip MSGB, then patients were called, the questions were asked and the answers were evaluated.
Results: The presence of dry mouth was statistically higher in patients with Sjögren’s Syndrome than histopathologically normal patient and sarcoidosis patients. In patients with Sjögren’s syndrome, the presence of dry eyes was found to be statistically significantly higher than the others. A statistically significant difference of clinical diagnosis distribution was observed between the patients with normal histopathological findings and patients with mild inflammation infiltration, granulomatous sialadenitis and lymphocytic sialadenitis.
Conclusion: Minor salivary gland biopsy is an easy and trusted method for establishing sarcoidosis and Sjögren’s Syndrome diagnosis and follow-up. Studies reveal that as more knowledge about disease immunology is collected and more sensitive techniques for interpretation of saliva and other serological markers are developed, less invasive or noninvasive techniques will come into question. Contemporarily, it will continue to be one of the main diagnostic tests for adjunctive diagnostic of multisystemic chronic diseases.

Published: February 2021

Objective: Nanotechnology is an emerging technology which has wide applications in many fields. Prime concern of research in nanotechnology is the synthesis of nano-material with the controlled size and shape. Recently, biosynthesis of metallic nano-particles has gained popularity owing to its eco-friendliness. The increasing use of Copper nanoparticles (CuNPs) in medicine and industry demands an understanding of their potential toxicities.
Methods: Genotoxicity of Copper nanoparticles was assessed using the in vitro micronucleus assay which is standard genotoxicity assay. In this study, Copper nanoparticle was tested in the absence and presence of the metabolic activation (2% v/v S9 mix). Human peripheral blood lymphocyte cultures were exposed to Copper nanoparticle, at 5 dose-levels between 0.125 to 2 µL/mL of culture medium in absence and presence of the metabolic activation system.
Results: Required level of cytotoxicity (55 ± 5% reduction in replicative index, i.e., cytostasis) was observed in absence of the metabolic activation at the test concentration of 2 µL/mL. Therefore dose levels selected for scoring of binucleated cells containing micronuclei were: 0.5, 1, and 2 µL/mL. From the obtained data of MNBN cells (Binucleated cells with micronuclei) for all three selected test concentration was found in the range of negative and vehicle control.
Conclusion: Our results concluded that, Copper nanoparticle did not induce statistically significant or biologically relevant increase in number of binucleated cells with micronuclei in absence and presence of the metabolic activation.

Objective: The aim of this study is to evaluate the gender specific effects of the high HbA1c levels in poorly controlled diabetic patients undergoing isolated coronary artery bypass grafting (CABG) procedure on long term morbidity, mortality and re-revascularization (2nd intervention). Methods: This study was conducted on 532 (346 (65%) males and 186 (35%) females) diabetic patients who underwent CABG procedure at a single center between January 2010 and December 2013.The patients were separated into 4 groups according to gender and preoperative HbA1c level (%). The group1 consisted of females with HBA1c level ≤7(n=46); the group 2 comprised female with HbA1c level >7(n=140); the group 3 comprised men with HbA1c level ≤7(n=117); and the group 4 comprised men with HbA1c level >7(n=229). The groups were analyzed and compared for postoperative complications and mortality. Results: No statistically significant difference was found among the groups in HbA1c levels and gender with respect to postoperative infection and mortality (p>0.05). The HbA1c level was determined to be statically significant and required the 2ndintervention (p:0.001; 95% CI: 1.249 (1.055,1.478)). Conclusion: This study suggested that there was no difference in mortality rates after CABG among the groups although the current risk calculator modules stated otherwise. However, the HbA1c levels were associated with a need for a secondary intervention on long term follow up period.
Multi-Objective Task Scheduling Optimization in Spatial Crowdsourcing
Authors: Alabbadi Afra A. , Abulkhair Maysoon F.
Published: February 2021

Recently, with the development of mobile devices and the crowdsourcing platform, spatial crowdsourcing (SC) has become more widespread. In SC, workers need to physically travel to complete spatial–temporal tasks during a certain period of time. The main problem in SC platforms is scheduling a set of proper workers to achieve a set of spatial tasks based on different objectives. In actuality, real-world applications of SC need to optimize multiple objectives together, and these objectives may sometimes conflict with one another. Furthermore, there is a lack of research dealing with the multi-objective optimization (MOO) problem within an SC environment. Thus, in this work we focused on task scheduling based on multi-objective optimization (TS-MOO) in SC, which is based on maximizing the number of completed tasks, minimizing the total travel costs, and ensuring the balance of the workload between workers. To solve the previous problem, we developed a new method, i.e., the multi-objective task scheduling optimization (MOTSO) model that consists of two algorithms, namely, the multi-objective particle swarm optimization (MOPSO) algorithm with our fitness function Alabbadi, et al. and the ranking strategy algorithm based on the task entropy concept and task execution duration. The main purpose of our ranking strategy is to improve and enhance the performance of our MOPSO. The primary goal of the proposed MOTSO model is to find an optimal solution based on the multiple objectives that conflict with one another. We conducted our experiment with both synthetic and real datasets; the experimental results and statistical analysis showed that our proposed model is effective in terms of maximizing the number of completed tasks, minimizing the total travel costs, and balancing the workload between workers.
An Exploratory Landscape Analysis-Based Benchmark Suite
Authors: Lang Ryan Dieter , Engelbrecht Andries Petrus
Published: February 2021

The choice of which objective functions, or benchmark problems, should be used to test an optimization algorithm is a crucial part of the algorithm selection framework. Benchmark suites that are often used in the literature have been shown to exhibit poor coverage of the problem space. Exploratory landscape analysis can be used to quantify characteristics of objective functions. However, exploratory landscape analysis measures are based on samples of the objective function, and there is a lack of work on the appropriate choice of sample size needed to produce reliable measures. This study presents an approach to determine the minimum sample size needed to obtain robust exploratory landscape analysis measures. Based on reliable exploratory landscape analysis measures, a self-organizing feature map is used to cluster a comprehensive set of benchmark functions. From this, a benchmark suite that has better coverage of the single-objective, boundary-constrained problem space is proposed.
