Realizing Learners’ Writing Problem from the Beginning: A Case Study
Authors: Wahyu Mahendra Made
Published: August 2020

Abstract The importance of writing has become a primary concern in teaching English as a foreign language. The skill of writing enables learners to generate ideas into certain organisation and awareness once the process of writing is undertaken. From writing, learners are also expected to be able to construct and use the language more accurately because they have enough time to think compared to have an oral activity. However, such an ideal situation can hardly be manifested due to particular problems faced by learners. This present study aims at investigating the struggling points of writing construction done by students. There were fourteen students who were purposefully selected as the subject of this study. In order to gather the supporting data, the researcher employs document study and direct observation. This study is expected to give contribution to help teachers confirming common problems faced by students during learning writing. Nevertheless, it also contributes to other prospective studies which are on the same interest with this present one. Keywords : Assessing Writing, Writing Problems, Writing Construction

Published: August 2020

Speaking as a language skill has been considered the most difficult one to master by the students especially in Songserm Wittaya School Songkla, Thailand. It was found that the majority of the students found it difficult to speak English fluently. As a productive skill, speaking is complex because learners need to acquire the accuracy and fluency in speaking. However, one EFL class showed a bit difference in the ability of speaking English because of their reading intensity. The design of the research was descriptive qualitative. The data were collected by a questionnaire for intensive reading and an interview on speaking to 30 students at 4/3 grade. The results of this research in general revealed that most of the students at grade 4/3 Thailand are good in speaking English due to their intensive reading that reached 50%. It was clearly seen from the analysis of some aspects of speaking (pronunciation, grammar, vocabulary, fluency and comprehension) in the interview section and questionnaire of reading intensity that 50% of the participants can speak English better through reading activity intensively. This finding implies that intensive reading has become a meaningful input for students’ speech production.
In the Presence of Photons: Portraying Light through Cinematography
Authors: Mahmud Nadia
Published: August 2020

Film is a medium that is impossible to exist without light. Essential to its production process is cinematography, a discipline in filmmaking that is directly responsible with visually presenting the information of a shot through a camera using the manipulation of time, lighting and framing. Frame distance describes the distance between a subject and the camera but more vital is the intent of application of frame distance as it is capable of implying meaning or eliciting a feeling in the viewer. The grammar of frame distance can be utilized to present structures, themes and styles of a film. Experimental, abstract films, although non-conformist to the rules of conventional cinema, may still be confined to the concepts and techniques in cinematography. Frame distances can help to distinguish patterns as well as emphasize details in an experimental film. The abstract, short film “Trapped Light”, explores the possibility of depicting the movement of light through transmissive and reflective materials.

How can we bring back rationality in public deliberation and political discourse? In this short paper I will try to answer these questions focusing on the role of emotions in contemporary democracies and the connections between post-truth, polarization and populism, while assessing a provisional proposal hopefully useful in building a working paradigm to bind politics to a more rational and prospective approach.
Values, Attitudes and Nature
Authors: Bendtsen Erik
Published: August 2020

An examination of the possibly right or true values involves a deep reflection on human life and the nature of values, and that includes all aspects of human life – i.e. includes basically our relationship to nature: to surrounding nature and ourselves. On this background we might discover the problematic relationship of human beings to nature on the basis of destructions of nature and of climate-change, but we might also start the other way round and ask: which are the true values and why? And then in contrast to these true and positive values ask: which values are false and destructive values?

Walmsley, C., & Kading, T. (Eds.). (2018). Small cities, big issues: Reconceiving community in a neoliberal era. Edmonton, Canada: Athabasca University.
Authors: Adatia Shelina
Published: August 2020

As the title suggests, the book Small cities, big issues: Reconceiving community in a neoliberal era takes a critical look at the complex social issues facing small Canadian cities – namely, Kamloops, Kelowna, Nanaimo and Prince George. Part one presents a reflection of displacement, isolation and Othering, echoing a dominant discourse of diversity as deficiency through communal responses to a variety of issues – specifically, homelessness, the street sex trade, illicit drug use, queerness, deinstitutionalization, the reintegration of parolees and finally, decolonization. While at first glance these issues may appear to be drastically different, they are in fact intimately connected by both the responses they elicit and the actions they can inspire. Individually and collectively, part one is a call to all Canadians – those who are typically silenced and those who are members of institutions, community groups and all levels of government – to collaboratively reframe our notion of community. In doing so, we commit to ensuring that each one of us, regardless of our differences, feels valued and included – a True North reflection of diversity as strength. Part two focuses on how we can build such inclusive communities by encouraging us to reflect on our social policies and our social responsibilities – thus calling into question the myth of Canada as fair and just. In essence, it is no longer enough to simply talk the talk of social inclusion, we must also walk the walk.
The Unwounded Skin Remodeling in Animal Models of Diabetes Types 1 and 2
Authors: KNAŚ M. , NICZYPORUK M. , ZALEWSKA A. , CAR H.
Published: August 2020

Diabetes mellitus types 1 and 2 are chronic diseases that cause serious health complications, including dermatologic problems. The diabetic skin is characterized by disturbances in collagen metabolism. A tissue remodeling depends on the degradation of extracellular matrix through the matrix metalloproteinases, which are regulated by e.g. the tissue inhibitors of metalloproteinases. The balance between matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) is essential to maintain homeostasis in the skin. The aim of this study was to determine the concentration of metalloproteinase 2, tissue inhibitor of metalloproteinase 3 and the concentration of collagen type 1 in unwounded skin of diabetes type 1 and 2 and healthy controls. The treatment of diabetes resulted in a significant decrease of MMP2, increase of TIMP3 and COL1 concentrations in the skin as compared to the untreated diabetic skin. The concentrations of MMP2 in the skin of treated rats did not show significant differences from the healthy control group. TIMP3 concentrations in the skin of treated rats are not returned to the level observed in the control group. Disturbances of the extracellular matrix of the skin are similar in diabetes type 1 and 2. Application of insulin in diabetes therapy more preferably affects the extracellular matrix homeostasis of the skin.

Oil Content and Fatty Acid Composition in Castor Bean Naturalized Accessions under Mediterranean Conditions in Chile
Authors: Román-Figueroa Celián , Cea Mara , Paneque Manuel , González María Eugenia
Published: August 2020

Castor bean is found in Chile between the Arica and Parinacota and Maule regions and is one the most important industrial crops worldwide because of the presence of ricinoleic acid in its oil. However, there is little information about it in our country. In this study, we analyzed the oil content and fatty acid profiles of 17 castor bean Chilean accessions from the Metropolitana and Valparaíso regions. The seed-oil was extracted using the Soxhlet extraction process, and the fatty acid profiles were determined using the GC-FID method. The oil content in castor bean Chilean accessions ranged between 45.7% and 54.0%. Among the 17 accessions analyzed, H-15 had the highest oil content (54.0%; p < 0.05), whereas the H-10 and H-08 accessions had the lowest oil content, (45.7% and 45.9%, respectively; p < 0.05). Ricinoleic acid was the most abundant fatty acid (between 87.64% and 89.83%) in the seed-oil. The highest level of ricinoleic acid was found in the H-08 accession. This was only statistically higher (p < 0.05) for three accessions, whereas the H-04 accession had the lowest ricinoleic acid content. Although the H-08 accession registered one of the least abundant oil contents, it had the highest amount of ricinoleic acid. No significant correlation was found between oil content and ricinoleic acid. Our study suggests that oil content does not influence the castor oil fatty profile. The high oil content and ricinoleic acid level registered in castor bean Chilean accessions justify their production in Chile and their utilization for developing bio-based products. Furthermore, Chilean castor bean could grow in semi-arid lands. However, further field studies are needed to identify the cultivars best suited for Mediterranean conditions.
Update on Acute Bone and Joint Infections in Paediatrics: A Narrative Review on the Most Recent Evidence-Based Recommendations and Appropriate Antinfective Therapy
Authors: Autore Giovanni , Bernardi Luca , Esposito Susanna
Published: August 2020

Acute bone and joint infections (BJIs) in children may clinically occur as osteomyelitis (OM) or septic arthritis (SA). In clinical practice, one-third of cases present a combination of both conditions. BJIs are usually caused by the haematogenous dissemination of septic emboli carried to the terminal blood vessels of bone and joints from distant infectious processes during transient bacteraemia. Early diagnosis is the cornerstone for the successful management of BJI, but it is still a challenge for paediatricians, particularly due to its nonspecific clinical presentation and to the poor specificity of the laboratory and imaging first-line tests that are available in emergency departments. Moreover, microbiological diagnosis is often difficult to achieve with common blood cultures, and further investigations require invasive procedures. The aim of this narrative review is to provide the most recent evidence-based recommendations on appropriate antinfective therapy in BJI in children. We conducted a review of recent literature by examining the MEDLINE (Medical Literature Analysis and Retrieval System Online) database using the search engines PubMed and Google Scholar. The keywords used were “osteomyelitis”, OR “bone infection”, OR “septic arthritis”, AND “p(a)ediatric” OR “children”. When BJI diagnosis is clinically suspected or radiologically confirmed, empiric antibiotic therapy should be started as soon as possible. The choice of empiric antimicrobial therapy is based on the most likely causative pathogens according to patient age, immunisation status, underlying disease, and other clinical and epidemiological considerations, including the local prevalence of virulent pathogens, antibiotic bioavailability and bone penetration. Empiric antibiotic treatment consists of a short intravenous cycle based on anti-staphylococcal penicillin or a cephalosporin in children aged over 3 months with the addition of gentamicin in infants aged under 3 months. An oral regimen may be an option depending on the bioavailability of antibiotic chosen and clinical and laboratory data. Strict clinical and laboratory follow-up should be scheduled for the following 3–5 weeks. Further studies on the optimal therapeutic approach are needed in order to understand the best first-line regimen, the utility of biomarkers for the definition of therapy duration and treatment of complications.
Arbitrary Phase Modulation of General Transmittance Function of First-Order Optical Comb Filter with Ordered Sets of Quarter- and Half-Wave Plates
Authors: Jung Jaehoon , Lee Yong Wook
Published: August 2020

Here we theoretically and experimentally demonstrated the arbitrary phase modulation of a general transmittance function (GTF) of the first-order optical comb filter based on a polarization-diversity loop structure, which employed two ordered waveplate sets (OWS’s) of a quarter-wave plate (QWP) and a half-wave plate (HWP). The proposed comb filter is composed of a polarization beam splitter (PBS), two equal-length polarization-maintaining fiber (PMF) segments, and two OWS’s of a QWP and an HWP with each set located before each PMF segment. The second PMF segment is butt-coupled to one port of the PBS so that its principal axis should be 22.5° away from the horizontal axis of the PBS. First, we explained a scheme to find four waveplate orientation angles (WOA’s) allowing the phase of a GTF to be arbitrarily modulated, using the way each component of the filter, such as a waveplate or PMF segment, affects its input or output polarization. Then, with the WOA finding method, we derived WOA sets of the four waveplates, which could give arbitrary phase retardations ϕ’s from 0° to 360° to a GTF chosen here arbitrarily. Finally, we showed phase-modulated GTF’s calculated at eight selected WOA sets allowing ϕ’s to be 0°, 45°, 90°, 135°, 180°, 225°, 270°, and 315°, and then the predicted results were verified by experimentally measured results. It is concluded from the theoretical and experimental demonstrations that the GTF of our filter based on the OWS of a QWP and an HWP can be arbitrarily phase-modulated by properly controlling the WOA’s of the four waveplates.

A drone be able to fly without colliding to preserve the surroundings and its own safety. In addition, it must also incorporate numerous features of interest for drone users. In this paper, an aerial mixed-reality environment for first-person-view drone flying is proposed to provide an immersive experience and a safe environment for drone users by creating additional virtual obstacles when flying a drone in an open area. The proposed system is effective in perceiving the depth of obstacles, and enables bidirectional interaction between real and virtual worlds using a drone equipped with a stereo camera based on human binocular vision. In addition, it synchronizes the parameters of the real and virtual cameras to effectively and naturally create virtual objects in a real space. Based on user studies that included both general and expert users, we confirm that the proposed system successfully creates a mixed-reality environment using a flying drone by quickly recognizing real objects and stably combining them with virtual objects.

R. raciborskii is known for growing under wide ranges of temperature and light. In temperate regions, however, low temperature and high light may serve as a stressful condition for invading tropical populations. The genetic basis of R. raciborskii’s adaptation to this combination of stresses are unknown. In this study, the growth rate and the expression of genes that may be crucial in the response to the chill/light stress of two R. raciborskii strains (differing in their climatic origin and toxicity) exposed to low temperature and high light were examined. Results showed that AMU-DH-30, a non CYN (cylindrospermopsin) producing strain isolated from the temperate region, exhibited under stress the upregulation of genes involved in the protein translation (rbp1, nusG, hflX), membrane fluidity (desA), photosynthetic activity (ccr2 and ftsH), and the accumulation of compatible solutes (asd). In contrast, a CYN producing Australian strain CS-505 was not able to adapt quickly and to continue growth during stress conditions. Intriguingly, CS-505 and AMU-DH-30 had a similar ability to resume growth when the stress conditions subsided. Moreover, in strain CS-505 the cyrB gene was significantly upregulated under the stress conditions. The presented results shed new light on the possible mechanisms involved in the response of R.raciborskii to chill/light stress.

The present in vitro study evaluated a new drill design to improve the temperature control during the osteotomies for dental implant installation, comparing with two drill designs that use conventional external irrigation. Three blocks of synthetic cortical bone were used for osteotomy procedures. Three groups were created: control group 1 (Con1), where a conical multiple drill system with a conventional external irrigation system was used; control group 2 (Con2), where a single bur with a conventional external irrigation system was used; and, test group (Test), where the new single bur (turbo drill) with a new irrigation system was used. Twenty osteotomies were made without irrigation and with intense irrigation, for each group. A thermocouple was used to measure the temperature produced during the osteotomies. The measured temperature were: 28.9 ± 1.68 °C for group Con1; 27.5 ± 1.32 °C for group Con2; 26.3 ± 1.28 °C for group Test. Whereas, the measured temperatures with irrigation were: 23.1 ± 1.27 °C for group Con1; 21.7 ± 1.36 °C for group Con2; 19.4 ± 1.29 °C for group Test. The single drill with a new design for improving the irrigation and temperature control, in comparison with the drill designs with conventional external irrigation.

Published: August 2020

Paper-based microfluidic devices have the potential of being a low-cost platform for diagnostic devices. Electrical circuit analogy (ECA) model has been used to model the wicking process in paper-based microfluidic devices. However, material characteristics such as absorption capacity cannot be included in the previous ECA models. This paper proposes a new model to describe the wicking process with liquid absorption in a paper strip. We observed that the fluid continues to flow in a paper strip, even after the fluid reservoir has been removed. This phenomenon is caused by the ability of the paper to store liquid in its matrix. The model presented in this paper is derived from the analogy to the current response of an electric circuit with a capacitance. All coefficients in the model are fitted with data of capillary rise experiments and compared with direct measurement of the absorption capacity. The theoretical data of the model agrees well with experimental data and the conventional Washburn model. Considering liquid absorption capacity as a capacitance helps to explain the relationship between material characteristics and the wicking mechanism.

Published: August 2020

An aluminum nitride (AlN) piezoelectric resonant infrared (IR) detector based on a Lame-wave resonator (LWR) and plasmon apertures was designed for dual-band sensing, and was investigated by using the finite element method (FEM) and finite difference time domain (FDTD) simulations. A plasmon structure with the apertures was designed on the surface of the detector in order to maintain electrical performance and to obtain ultrahigh dual-band IR absorption. The electrical performance of the LWR with the plasmon apertures was comparable to that of the LWR with floating electrodes, which was found to be superior to that of the LWRs with plasmon particles or open electrodes. Both of the rectangle aperture and cross-shaped aperture absorbers can achieve ultrahigh dual-band absorptions of up to 97%, and the cross-shaped aperture absorber is insensitive to the polarization angle. Moreover, a detailed optimization analysis for the thermal properties of the detector was conducted to obtain favorable responsivity and response speed. The calculated results demonstrate that the proposed resonant detector has great potential applications in IR detection.

Background: Due to an aging society, more and more surgeons are confronted with fragility fractures of the pelvis (FFPs). The aim of treatment of such patients should be the quickest possible mobilization with full weight-bearing. Up to now however, there are no data on loading of the lower extremities in patients suffering FFPs. We hypothesized to find differences in loading of the lower limbs. Methods: 22 patients with a mean age of 84.1 years were included. During gait analysis with insole-force sensors, loading on the lower extremities was recorded during early mobilization after index fracture. Results: Especially the average peak force showed differences in loading, as the affected limb was loaded significantly less {59.78% (SD ± 16.15%) of the bodyweight vs. 73.22% (SD ± 14.84%) (p = <0.001, effect size r = 0.58)}. Furthermore, differences in loading in between the fracture patterns of FFPs were observed. Conclusion: This study shows that it is possible to reliably detect the extremity load, with the help of an insole device, in patients presenting with fragility fractures of the pelvis. There is great potential to improve the choice and time of treatment with insole-force sensors in FFPs in future.
