Indonesian lexical bundles in research articles: Frequency, structure, and function
Authors: Budiwiyanto Adi , Suhardijanto Totok
Published: October 2020

Recent studies show that lexical bundles in English are pervasively found in academic discourse. In addition, the characteristics of lexical bundles found vary and differ across registers and genres. Nevertheless, it is still interesting to carry out in languages other than English. This study aims to discover the characteristics of Indonesian lexical bundles that cover frequency, structure, and function in research articles. This study adopted a mixed-method. Identification of the lexical bundle was carried out using WordSmith 7.0 on a corpus comprising 3,125,546 words, taken from 1126 texts, and consisting of six disciplines. With a frequency threshold of 40 per million words and a minimum distribution of 5 texts, 197 lexical bundles have been obtained, consisting of three- to six-word bundles with a total occurrence of 51,813 times. In terms of structure, the incomplete structure is dominating the bundles by 78.7%, with a total frequency of occurrence 38,749 times. This research finds that the pattern of lexical bundles can be classified into five types: noun-based, prepositional-based, verb-based, adjective-based, and clause-based bundles. Lexical bundles in research articles are generally clause-based (49.2%). This indicates that Indonesian lexical bundles vary in structure. The use of clause fragments and passive verbs are the main features in this genre. In terms of the discourse function, research-oriented bundles are the functions that are commonly used, while participant-oriented bundles are the least. Each discourse function has its own structural characteristics. It is also found that one lexical bundle can have two functional categories. These findings contribute to a better understanding of the characteristics of written academic discourse. From the pedagogical point of view, the ﬁndings can be used as learning material for both native and non-native speakers.
A study of Pagu proverbs: Saving an endangered language of North Halmahera
Authors: Perangin-Angin Dalan M. , Dewi Novita
Published: October 2020

Pagu is an endangered  Non-Austronesian  language spoken  in North Halmahera, Indonesia. This research is an endeavor to save the language specifically through documenting and studying its proverbs in order to reveal the linguistic patterns and meanings of these proverbs. A mixed qualitative and quantitative method is applied to see their structure and characteristics (Angouri, 2010; Rasinger, 2010). It presents a number of stylistic and structural features of Pagu proverbs based on the preliminary research of 2012-2014 (D. Perangin-Angin, 2013) and recent online communication with one of the Pagu  community leaders. The findings show that, first, metaphor and simile are the most common features in Pagu proverbs that function to express politeness through indirectness (Brown Levinson, 1987; Thomas, 2014). Second, structurally it was found out that Pagu proverbs do not follow the typical Europeans structure such as relationships between elements (Dundes, 1975), number of clause, types of sentences (Mac Coinnigh, 2015), and types of figurative languages (e.g. Eaglestone, 2000). But rather, Pagu proverbs vary in different structures that intend to express the Pagu culture and thought namely indirect politeness.
Improving students’ arguments through collaborative learning
Authors: Shinta Dona Kumala , Filia F.
Published: October 2020

The ability to produce argumentation is crucial for university students’ academic achievement and upcoming careers. Developing and organizing ideas to create an argument, requires students’ thinking skills. Attempts to improve students’ written arguments through collaborative learning have been conducted in numerous studies. However, there are few studies on improving students’ spoken arguments through collaborative learning, especially in Bahasa Indonesia.  Therefore, this research aims to investigate how students’ arguments improve through collaborative learning. This research uses a one group pre-test post-test design method. The participants were 21 undergraduate students from a university in Indonesia. Students were presented a video of Indonesia’s 2019 presidential debate and an argumentation model as the stimulus. Students’ arguments were recorded, transcribed, translated and analyzed to detect any improvements from the pre-test compared to the post-test. Findings show that through collaborative learning students can produce more argument component parts leading to a higher level of argument. They are also able to use their thinking skills of remember, understand, apply and analyze in the learning process. As conclusion, collaborative learning can be considered as a classroom strategy in improving students’ arguments, from producing claim, data and warrant in arguments to improving awareness in applying other component parts of backing, rebuttal and qualifier. However, there are no detections of a new component part found in students’ argument or an implementation of the highest order thinking skills, that is create.
Role of Regional Language Background and Speech Styles on the Production of Voice Onset Time (VOT) in English among Indonesian Multilinguals
Authors: Zen Evynurul Laily
Published: October 2020

This paper seeks to contribute to the nature of cross-linguistic transfer in the production of English Voice Onset Time (VOT) by adult multilingual speakers in Indonesia in view of how different regional home languages and speech settings shape the phonetic realizations. Three adult multilinguals participated in this pilot project. They are all learners of English as the third language (L3) at the Department of English of a state university in Malang, Indonesia who acquire different regional home languages – Javanese, Sundanese, and Madurese – as the first language (L1) and speak Indonesian as the second language (L2). The participants’ production of bilabial stop consonants of English /p/ and /b/ were elicited from two different speech settings; a careful speech via text readings (monologue and dialogue) and wordlist reading, and a spontaneous speech through natural conversation among participants. 21 tokens from each participant were then analyzed acoustically in Praat. The findings show that the bilingual speaker with L1 Sundanese consistently produced the shortest VOT values of both /p/ and /b/. The Javanese speaker produced the intermediate lag, whereas the Madurese speaker produced the longest aspiration interval. It is shown that the Sundanese language provides the strongest transfer effect, while Madurese gives the least effect. In light of cross-linguistic transfer, however, the overall VOT productions clearly put forth evidence of L1 phonological transfer. The production of non-native bilabial stop VOTs of English is largely due to the absence of this phonetic property in Javanese and Sundanese while Madurese shows marginal similarities. The findings also demonstrate that speech styles play only a marginal role in determining the production of VOTs that the VOTs of /p/ and /b/ in careful speech is found to be slightly longer than in the spontaneous settings. This study makes an original contribution to the area of phonological acquisition in adult speakers by giving attention to the understudied languages of Indonesia in order to more fully understand the interaction of different language systems in multilingual language acquisition and development.
Understanding writing teachers’ technological pedagogical content knowledge: A study with five in-service teachers
Authors: Cheung Yin Ling , Jang Hari
Published: October 2020

The growing emphasis on emerging technologies in education has required in-service teachers to develop more technological knowledge. However, little is known about the application of technological pedagogical content knowledge (TPACK) on subject matter knowledge in language teaching. This qualitative study examined five writing teachers’ implementation of instructional objectives, instructional strategies, and technologies to teach writing as well as their assessment of learning using the TPACK-Writing perspective. Lesson observations were conducted for each teacher. Adopting a case study design, the observation transcripts were analyzed with a focus on the teachers’ execution of the instructional objectives, instructional strategies, and technologies to teach writing as well as their assessment of learning. The results showed that the complex nature of writing pedagogy with TPACK-Writing as a construct was mediated by cultural factors such as an examination-oriented system and teacher-centered pedagogy. The results also suggested that the application of TPACK-Writing should involve a student-centered approach rather than a teacher-centered approach, which implies the need for teachers to acquire a high level of knowledge of learners and the instructional context to promote effective pedagogy.

Published: October 2020

Results of comparative study of posterior interbody fusion (PLIF) and transforaminal interbody fusion (TLIF) in degenerative lumbar spine pathology are presented. Total number of patients was 101. In 47 patients (1st group) transpedicular fixation, decompression and interbody fusion with one cage (TLIF) was performed. In 54 patients (2nd group) transpedicular fixation via posteromedial approach, decompression of intracanal neurovascular structures and interbody fusion with two interbody implants (PLIF) was applied. Complex evaluation of surgical treatment results was performed in 52 patients in 6-12 months after surgery. It was shown that application of either of the techniques resulted in 95-98% cases of interbody block formation. Differential approach to application of those interbody fusion techniques and the advantages of TLIF over PLIF, i.e. simplicity and higher safety of performance, lower intraoperative blood loss and duration of surgical intervention, were presented.

Authors: Ogaryov E. V , Morozov A. K
Published: October 2020

Multispiral computed tomography (MSCT) is a method of choice for evaluation of bone structure condition, as well as for visualization of growth zones, main and additional ossific nuclea of the articular elements. Besides, MSCT provides precise evaluation of spatial orientation of hip joint components, pattern of bone fragments displacement in traumatic injuries, localization of pathologic focus in bone pathology and degree of adjacent anatomic structures involvement. Contrast enhancement (double-contrast technique) markedly widens potentialities of this method as it enables to evaluate the condition of articular cartilage and soft tissue structures that is the most actual in young children.

Published: October 2020

During the period from 2001 through 2012 one hundred forty eight patients (mean age 49 years) underwent surgical intervention for periprosthetic pyo-inflammatory complications. Removal of joint implant was performed in terms from 1 month to 25 years after total hip replacement. In 105 (72.4%) patients Girdlestone operation was performed after primary and in 43 (27.6%) — after revision arthroplasty. Removal of joint implant, hip fistulosequestrnecrectomy and weight bearing neoarthrosis formation was performed. For neoarthrosis formation in acetabular dysplasia and vast resection of proximal femur an external fixation device was used. Good results were achieved in 68 (70.8%) patients: inflammatory process was arrested and weight bearing ability of the limb was restored. Satisfactory result was observed in 28 (29.2%) patients. In 15 (15.6%) out of them inflammatory process was cupped off but no adequate weight bearing neoarthrosis was formed. Girdlestone operation is the last possibility to restore the weight bearing ability of the limb and is used in patients in whom revision arthroplasty cannot be performed.

Published: October 2020

Study of biocompatibility and antibacterial properties of argentum-containing tricalcium phosphate (TCPh) with various degree of substitution by argentum (TCPh-Ag) was performed on rat model. Biocompatibility was studied using subcutaneous implantation of TCPh-Ag (0.5). Antibacterial properties were studied in 5 subgroups (A-E), 5 animals in every group. At first step a distal femur defect was formed and infected by 24-hours cultures of clinical isolates of methicillin-resistant S. aureus. Second step (subgroups B-E) consisted of revision intervention with implantation of either TCPh or TCPh-Ag with various degree of substitution by argentum (0.04, 0.2 and 0.5) into infected defect. Histologic examination of tissue samples with subcutaneous implantation of TCPh-Ag (0.5) showed the absence of inflammatory and rejection reactions that was indicative of study material biocompatibility. Optimim degrees of Ag substitution were 0.2 and 0.5 that provide high antibacterial activity at monotherapy of femur bacterial infection in rats with minimum pronounced toxic effect on the surrounding tissues and bone marrow.

Published: October 2020

Twenty eight patients with old postpartum ruptures of pubic symphysis complicated by functional bladder disorders were operated on during the period from 2000 to 2013. Time interval between vaginal delivery and pelvic ring stabilization made up from 1 month to 8 years. Clinical and roentgenologic examination enabled to detect predisposing factors for neurogenic, i.e. hyperactive bladder development that were treated surgically. In all cases plate osteosynthesis for pubic symphysis and fixation of sacroiliac joint with cannulated screws was performed. Subjective improvement of patients’ condition as well as the results of uroflowmetry and complex urodynamic investigation enabled to conclude that orthopaedic reconstruction of pelvic ring in old obstetric ruptures of pubic symphysis was an effective and reliable technique for the treatment of bladder dysfunction.

Published: October 2020

A filtração consiste na separação entre fase líquida e sólida, em que uma polpa ao ser forçada a passar por meio poroso, subdivide-se em filtrado e torta de filtração. Dessa forma, o objetivo foi construir módulo didático filtro presa para utilizar em aulas práticas e pesquisas em escala laboratorial. Para o dimensionamento realizou-se experimentos em filtração á vácuo, a fim de comprovar a eficiência do módulo construído com três tipos de meios filtrantes (algodão, brim e jeans). Através dos experimentos, foi possível determinar a curva de calibração (Concentração x Turbidez) por meio da turbidimetria de valores conhecidos de concentração, obtendo a equação da curva por regressão linear. Utilizando a equação da curva determinaram-se valores de concentração dos filtrados dos processos de filtração. Por sua vez, a eficiência da filtração foi calculada relacionando a concentração da suspensão com a concentração do filtrado, apontando uma melhoria média de 18,3%, determinando o jeans como meio filtrante mais eficiente.

Published: October 2020

Objetivo: Evaluar la calidad de vida en un grupo de pacientes con linfedema por cáncer de seno en la ciudad de Medellín. Metodología: Se realizó un estudio cuantitativo de tipo descriptivo correlacional, en el que se analizó la relación de la calidad de vida con la sintomatología, tratamientos médicos recibidos y perímetros del brazo en 11 mujeres con linfedema. Se valoró el dolor, perímetros de ambos brazos y se utilizó el cuestionario de calidad de vida FACT B+4. Resultados: A partir de las correlaciones de Spearman se identificó que, para la calidad de vida y los perímetros del brazo afectado, hubo una correlación inversa y no significativa, lo que indica que no existe una percepción negativa frente a la calidad de vida pese al linfedema. Hubo una correlación inversa y significativa entre el número de tratamientos y la calidad de vida (a más número de tratamientos recibidos, menor calidad de vida según la percepción de las participantes). Así mismo, la percepción de calidad de vida se correlacionó de modo inverso con el dolor. Conclusión: La calidad de vida se ve influenciada por la cantidad de tratamientos oncológicos recibidos, dichos tratamientos tienen efectos colaterales e impactan el bienestar. El dolor es una complicación que influye negativamente en la calidad de vida, más aún si se trata no se trata oportunamente.
Privación sensorial temprana durante el neurodesarrollo y sus consecuencias cognitivas
Authors: Álvarez Restrepo Juan Felipe , Becerra-Hernández Lina Vanessa
Published: October 2020

La aparición progresiva de habilidades sensoriales, motoras y cognitivo-afectivas en el humano a lo largo de su desarrollo es un reflejo de cambios fisiológicos que se gestan al interior del sistema nervioso. Dichos cambios hacen parte de procesos dinámicos y dependen, después del nacimiento, de la actividad eléctrica inducida por la experiencia. Considerando lo anterior, el sistema nervioso en desarrollo constituye una especie de protomapa, sobre el que la experiencia moldea características moleculares, neuroquímicas y de conectividad, que se reflejan en las actividades emergentes del sistema. La eviden­cia que soporta la importancia que la influencia experiencial tiene sobre el desarrollo del sistema nervioso viene en aumento. Esta revisión reúne información sobre estudios en modelos biológicos y en humanos sometidos a privación sensorial y ambiental. Se enfatiza en la caracterización de los rasgos cognitivos y sociales.

El rendimiento es un importante atributo de calidad de un sistema de software. La Ingeniería de rendimiento del software comprende las actividades de análisis, diseño, construcción, medición y validación, que atienden los requerimientos de rendimiento a lo largo del proceso de desarrollo de software.  En los sistemas de software que utilizan comunicación basada en mensajes, el rendimiento depende en gran medida del middleware orientado a mensajes (Message-Oriented Middleware – MOM). Los arquitectos de software necesitan considerar su organización, configuración y uso para predecir el comportamiento de un sistema que use tal plataforma. La inclusión de un MOM en una arquitectura de software requiere conocer el impacto de la mensajería y de la infraestructura utilizada. Omitir la influencia del MOM llevaría a la generación de predicciones erróneas. En este artículo se explora tal influencia, mediante el modelado y la simulación basados en componentes, utilizando el enfoque Palladio Component Model – PCM. En particular, una aplicación modelada en PCM fue adaptada para incluir comunicación basada en mensajes. Las simulaciones sobre el modelo, mediciones sistemáticas y pruebas de carga sobre la aplicación permitieron determinar cómo cambios introducidos en el modelo influyen en las predicciones del comportamiento de la aplicación en cuanto a rendimiento y confiabilidad. Fue posible identificar un cuello de botella que impacta negativamente el rendimiento y la confiabilidad del sistema original. La introducción de MOM mejoró la confiabilidad del sistema, a expensas del rendimiento. La simulación del rendimiento basado en componentes reveló diferencias significativas respecto de los experimentos basados en pruebas de carga y mediciones.

Emergencies that occur during the transportation process in rail transport entail variable over time values of loss of life, human health and material damage. Increasing the response time of emergency response services leads to an increase in the consequences and scale of incidents. One of the parameters determining delays in the response of special services and structures is the time taken to bring information from the emergency site, from the moment it was discovered and the transfer of information about it to the moment that this information was communicated to all officials of the railway structures and other emergency response services of the territorial unit within which the accident occurred. The paper presents the main theoretical calculations of a mathematical model describing the system of information interaction and exchange when communicating information about an emergency situation that occurred during the transportation process on the Sverdlovsk railway and developed a simulation model in the package of MATLAB application programs and SimEvents libraries.

The paper proposes a method that allows forecasting a level of passenger injuries at interaction with baggage in emergency situations. The authors have created computer models of emergency situations that are caused by a collision of passenger rolling stock with an obstacle on a track in the form of a motorcar and a freight car, and by swinging of a car on a side wall. The model of the investigated car is supplemented by elements of passenger car interior, models of anthropometric dummies and baggage. The anthropometric dummies are located on passenger seats, the baggage is presented by rigid bodies that are located on parcel shelves. As a result, the authors have got the values of injury criteria at interaction of passengers with baggage.

The paper shows investigations of relationship between the length of approach sections of level crossing safety installation and braking distances of trains. It is established that the existing methods of calculating approach sections of automatic level crossing safety installation don’t guarantee, if necessary, a full stop of a train by braking before a crossing after it’s closure. The authors have formulated a condition when a train can be stopped before a closed crossing occupied by a motor vehicle. They have also carried out a verification of the existing automatic level crossing safety installation systems and established that such systems don’t comply the formulated condition, so the full stop of a train is not guaranteed. So, the authors have proposed measures on developing an algorithm of automatic level crossing safety installation operation for the control of automatic stop of a train before a crossing occupied by a motor vehicle. It is shown that the development of engineering is on a level sufficient for realization of this suggestions.

Published: October 2020

One of most important ecological tasks for carriage engineering is the abatement of vibrations in passenger cars. Nowadays before forwarding to the consumer all produced and modernized car models pass a mandatory certification procedure. During the procedure all characteristics of cars are thoroughly investigated including vibroacoustic characteristics because the values of these indicators significantly affect health of passengers and staff. Nevertheless, data from medical examination of guards show that the number of illnesses caused by the influence of excessive vibration levels doesn’t decrease. The paper proposes a variant of the problem solution that allows decreasing levels of vibration in passenger cars at frequencies above 16 Hz.

The paper analyses operational indicators of electric locomotives with commutator and induction motor traction motors. It is established that, due to the inherent limitations of the commutator motors, electric locomotives can work with rated power in speed range of 51.2–79 km/h, at maximum speed of 100 km/h power doesn’t exceed 68 % of rated. In order to increase the energy efficiency the authors have proposed to widen by several times the speed range at a constant rated power and reduce as much as possible operation at overload modes. Induction motors have significantly wider ranges for electromagnetic, thermal and mechanical loads. The calculation of losses in converter of phases and frequency for induction motors with various number of phases showed that total losses of three-phase motor reach 1.9 %, losses of motor with even number of phases doesn’t exceed 0.8 %. As a result, it is preferable to use traction motors with 8-phase winding.
