Authors: Putera Jaya Hariswan , Petrus Ismail , Kurniawan Dedi
Published: February 2022

This study was aimed at finding out the performance of listening comprehension, problems faced, the causes of the problems, and the relationships between the problems and their causes. The samples of this study were the students of bachelor program of an English education study program. The data were the TOEFL prediction listening comprehension test and questionnaires. It was found that 30% of the samples were in a fair listening category and 70% were in a poor listening category. The students’ main problems in listening were then categorized as listeners, listening materials, and listening settings. The causes of the problems were specified as linguistic knowledge, pronunciation, concentration, and environment. The data were analyzed using chi-square association with p-value 514.84 which was greater than the critical value of 179.58. Therefore, there is a significant relationship between the listening problems and the factors causing the problem.
Deferiprone attenuates neuropathology and improves outcome following traumatic brain injury
Authors: Daglas Maria , Truong Phan , Miles Linh , Juan Sydney , Rao Sonia , Adlard Paul
Published: February 2022

Background and Purpose: Traumatic brain injury (TBI) remains a leading
cause of mortality and morbidity in young adults. The role of iron in
potentiating neurodegeneration following TBI has gained recent interest
since iron deposition has been detected in the injured brain in the
weeks to months post-TBI, in both the preclinical and clinical setting.
A failure in iron homeostasis can lead to oxidative stress, inflammation
and excitotoxicity; and whether this is a cause or consequence of the
long-term effects of TBI remains unknown. Experimental approach: We
investigated the role of iron, and the effect of therapeutic
intervention using a brain-permeable iron chelator, deferiprone, in a
controlled cortical impact mouse model of TBI. An extensive assessment
of cognitive, motor and anxiety/depressive outcome measures were
examined, and neuropathological and biochemical changes, over a 3-month
period post-TBI. Key Results: Lesion volume was significantly reduced at
3 months, which was preceded by a reduction in astrogliosis and a
preservation of neurons in the injured brain at 2 weeks and/or 1-month
post-TBI in mice receiving oral deferiprone. Deferiprone treatment
showed significant improvements in neurological severity scores and
locomotor/gait performance, and cognitive function, and attenuated
anxiety-like symptoms post-TBI. Deferiprone reduced iron levels,
oxidative stress and altered expression of neurotrophins in the injured
brain over this period. Conclusion and Implications: Our findings
support a detrimental role of iron in the injured brain and suggest that
deferiprone (or similar iron chelators) may be promising therapeutic
approaches to improve survival, functional outcomes and quality of life
following TBI.
Large-scale siting of sand dams: a participatory approach and application in Angolan drylands
Authors: Piemontese Luigi , Limones Natalia , Castelli Giulio , Grazio Alice , Bresci Elena
Published: February 2022

Sand dams are simple and effective structures built across ephemeral
riverbeds in arid/semi-arid regions to harvest water within sand pores
and increase water availability and quality for rural communities. The
complex morphological, hydrological, social and economic conditions that
make sand dams a beneficial tool for water resilience are largely
influenced by the siting phase. Proper location of a sand dam can reduce
community’s travel time to water points, reduce water conflicts and
increase food security through expansion of irrigated agriculture. On
the other hand, a misplacement of sand dams can, at worst, increase
disparities in water access and increase local conflicts. To approach a
viable siting of sand dams, most projects are developed and delivered
with the community through a bottom-up approach. However, in case of
large-scale project, remote sensing and biophysical analysis are the
dominant approach, leaving the socio-economic component at the margins
of the siting strategy and eventually affecting the benefits to local
communities. In this paper, we propose a large-scale participatory
methodology to sand dams siting, which draws on mixed-methods connecting
the conventional top-down biophysical analysis with bottom-up
participatory research. We first describe the generic approach developed
for sand dams siting in Namibe, a semi-arid region of South-west of
Angola, then we draw on our case to propose a generic approach to
large-scale participatory siting beyond Namibe.
The potential role of interleukin-6, endotoxin and C-reactive protein as standard biomarkers for acute appendicitis in adults
Authors: Dimic Sasa , Dimic Ivana , Elek Zlatan , Radojkovic Milan
Published: February 2022

Introduction/Objective. Acute appendicitis (AA) is by far the most frequent urgent condition in abdominal surgery and numerous biomarkers may help the physician to diagnose and even predict the severity of the disease. The objective of the paper was to determine the accuracy of C-reactive protein (CRP), interleukin-6, and endotoxin level and compare it with the diagnostic value of Alvarado score (AS) in adults surgically treated for AA. Methods. Sixty-seven patients were diagnosed with AA using AS. Prior to surgery serum levels of inflammatory biomarkers were determined and together with AS were respectively compared to the results of histopathological analysis of specimens. The patients were divided into three group according to the histopathological assessment. Results. The univariate analysis revealed that the increase of CRP level by one unit increases the probability of complicated AA (CoAA) occurrence by 1% (1.00?1.02, p < 0.05). ROC curve analysis has revealed that CRP has better capacity to predict suppurative AA (SAAs)/CoAAs than catarrhal AA (CAA), with the cut-off value of 19.45. The increase of AS value by one unit produced 2.98-fold increase of the probability of CoAA occurrence (1.60?5.57, p < 0.001), while positive AS value increases the probability of CoAA occurrence 24.67 times (4.94?123.12; p < 0.001). ROC curve analysis demonstrated that AS may predict CoAAs better than CAAs/SAAs, with the cut-off value of 8.50. Conclusion. AS and CRP should be routinely used combined as powerful tools for the diagnosis and prediction of complicated AA.

Authors: Karl Florian M. , Winkler Christiane , Ziegler Anette-Gabriele , Laxy Michael , Achenbach Peter
Published: February 2022

Objective: Evaluation of costs associated with public
health screening for presymptomatic type 1 diabetes in 90,632 children as part
of the Fr1da study in Bavaria and in forecasts for standard care.

Research Design and Methods:
We report on resource utilization and direct costs for screening-related
procedures in the Fr1da study coordination center and laboratory, and in
participating pediatric practices and local diabetes clinics. Data was obtained
from Fr1da study documents, an online survey among pediatricians, and
interviews and records of Fr1da staff members. Data were analyzed with tree models
that mimic procedures during the screening process. Cost estimates are
presented as they were observed in the Fr1da study and as they can be expected
in standard care for various scenarios.

Results: The
costs per child screened in the Fr1da study were €28.17 (95% CI: 19.96; 39.63)
and the costs per case diagnosed with presymptomatic type 1 diabetes were
€9,117 (6,460; 12,827). Assuming a prevalence of presymptomatic type 1 diabetes
of 0.31%, as in the Fr1da study, the estimated costs in standard care in
Germany would be €21.73 (16.76; 28.19) per
screened child and €7,035 (5,426; 9,124) per diagnosed child. Of the projected
screening costs, €12.25 would be the costs in
the medical practice, €9.34 for coordination and laboratory, and €0.14 for
local diabetes clinics.

Conclusions: This
study provides information for the planning and implementation of screening
tests for presymptomatic type 1 diabetes in the general public and for the analysis
of the cost-effectiveness of targeted prevention strategies.

Published: February 2022

Objective: The Functional Independence Measure (FIM™) and spinal cord injury (SCI)-specific Spinal Cord Independence Measure (SCIM) are commonly used tools for outcome measurement and quality reporting in rehabilitation. The objective of this study was to investigate the psychometric properties of FIM™ and SCIM and to equate the 2 scales.Methods: First, content equivalence of FIM™ and SCIM was established through qualitative linking with the International Classification for Functioning, Disability and Health (ICF). Secondly, a Rasch analysis of overlapping contents determined the metric properties of the scales and provided the empirical basis for scale equating. Furthermore, a transformation table for FIM™ and SCIM was created and evaluated. Subjects: Patients with SCI in Swiss inpatient rehabilitation in 2017–18.Results: The ICF linking and a separate Rasch analysis of FIM™ restricted the analysis to the motor scales of FIM™ and SCIM. The Rasch analysis of these scales showed good metric properties. The co-calibration of FIM™ and SCIM motor scores was supported with good fit to the Rasch model. The operational range of SCIM is larger than for FIM™ motor scale.Discussion: This study supports the advantage of using SCIM compared with FIM™ for assessing the functional independence of patients with SCI in rehabilitation.
LAY ABSTRACTIn our study we compared two rehabilitation outcome assessment tools commonly used to measure functional independence in Spinal Cord Injury: the Functional Independence Measure (FIM™), a general tool, and the Spinal Cord Independence Measure (SCIM), a tool specifically developed for Spinal Cord Injury rehabilitation. We first compared the content of the two tools using the International Classification of Functioning Disability and Health (ICF). Then we tested their measurement properties and put them on a common measurement scale, which allows to directly compare scores of the two tools. The common measurement scale was obtained by mean of a so-called Rasch analysis. The results showed that the FIM™ motor items can be compared to the SCIM items from a content but also from a metric point of view. The study showed an advantage in using the SCIM compared to the FIM™ for assessing the functional independence of patients in Spinal Cord Injury rehabilitation.

HISTORICAL AND URBAN RESEARCH OF DEFENSE COMPLEXES OF VINNITSA OF RUS’-LITHUANIAN ERA (14th-16th CENTURIES)
Authors: Lytvynchuk Illia
Published: February 2022

In this article for the first time the methods of the complex historical and town-planning analysis of urban defense complexes of the city of Vinnytsia formed during the Grand Duchy of Lithuania is applied. The author compares chronicle and act sources, historical cartography and the results of modern field research to establish the location of ancient castle and urban fortifications. The thesis about the formation of the primary urban structure of Vinnytsia during the Lithuanian era according to the principles of urban planning on Rus’ law is proved. Two stages of town-planning development of defense complexes of the city of Vinnytsia are singled out. The first stage is dated to the late 15th middle 16th century. At this time, a castle appears on the basis of a probable ancient Rus’ settlement on Castle Hill in the Old Town area. Next to it, but at a distance, the city center is being built - a fortified post. Planning relics of the ancient city center could be read now. The topological unity of Vinnytsia city center planning with the cities of the medieval Romanesque and Old Rus’ tradition in the cities of Western Europe and Ukraine has been established by means of comparative analysis. Reconstruction of the view of Vinnytsia Castle on Castle Hill at the beginning of 16th century according to the lustrations of 1545 and 1552. The second period is associated with the construction of a new castle until 1558 on the opposite (right) bank of the Southern Bug and the development of a new middletown near castle. At this time, the Ukrainian lands are still dominated by the same principles of urban planning that existed during the construction of the Old Town. Therefore, the outline of the city fortifications, the market square and the parcelling of the New Vinnytsia city are similar to those in the Old City. Instead, the castle is already merging with the city's fortifications into a single system, which allows us to talk about a holistic urban defense complex.
Post-ideology of Post-liberalism: Genesis, Essence, Purpose
Authors: Tyapin Igor N.
Published: February 2022

The article examines the theoretical basis of the post-ideology phenomenon as the key element of pseudo-rationality in political and sociocultural reality of post-liberal society. Pseudo-rationality is defined as the result of the deformation of the most important kinds of knowledge in the modernist epoch, and it appears to be the result not of the development process of knowledge transdisciplinarity, computer dependence expansion and everyday existence virtualization, but of the artificial synthesis of separate characteristics of various forms of extrascientific rationality. The author examines pseudo-rationality manifestations in the easy transition into one another of pseudo-scientific, post-(pseudo-)philosophic and post-ideological doctrines, that are meant to convince the society in the positivity of national state dismantling, technobiological inequality and spiritual and bodily dehumanization. He substantiates the direct connection of pseudo-rationality with ideological products of post-modernity. Post-ideology that defies the culture unity and ideological content, at the same time pursues the thesis of westernized globalization inevitability and positivity; causes artificial conflicts and creates censorship mechanisms. He comes to the following conclusion: as the flexibility and indistinctness of the boarders among separate pseudo-rationality types are higher than those of their rational analogs, post-ideology gives unlimited possibilities of manipulation to the subjects of ideological process.

Non-formal education is intended for people who specifically need education as a complement, addition to, and substitute for formal education. Non-formal education can be used as a support, a complement, an addition to the education obtained by a person in formal education, where non-formal education is held for people who need this education. Non-formal education includes equality education, training and work skills, functional literacy, women's empowerment, youth, PAUD, life skills, and others.Community Reading Park (TBM) is one of the institutions in the field of non-formal education. Community reading parks can be interpreted as non-formal educational institutions that focus on providing knowledge services in the form of print media (books) or electronic media (internet). On the other hand, the community reading park also functions as a supporter of non-formal education activities, one of which is literacy education.Fashion design is a non-formal education program that focuses on the science of designing and sewing clothes. This program is implemented in various non-formal educational institutions, one of which is the Community Reading Center (TBM). There is an important component in the fashion design program, namely facilities for learning. Learning facilities are said to be an important component because they are able to encourage a person's interest in participating in a learning program. Interest in learning is an element in supporting the success of the learning program. Without high interest from program participants, it will create failure in a program. Facilities have a relationship with interest in learning in achieving a successful program. Keywords: TBM and non-formal education

Published: February 2022

The surface roughness quality of machining product plays important role when it contacted with other machine components. That quality depends on several parameters setting, such as material, cutting tool, cutting condition and operator skill. The aim of this study is to obtain the optimum setting of turning parameters by using Taguchi method. Three control factors: cutting speed, depth of cut, and feeding at three different levels are selected. A series CNC turning process on AISI 1045 material were performed using L9 (3)3 orthogonal array with cutting fluid. Insert carbide cutting tool is used in the experiment. In order to reveal the optimum machining parameter, smaller the better is quality characteristic selected for surface roughness examination of workpiece. Analysis of experiment results revealed that higher cutting speed, low feed, low depth of cut respectively, provides fine surface quality of machined workpiece. Moreover, feed f parameter was found most influence to the surface rougness quality with 53.73% contribution, cutting speed v provides 23.28% contribution, and depth of cut a provides 17.87% contribution. Confirmation experiment shows that level 3 of cutting speed, level 2 of cutting depth, and level 1 of feed deliver smoothest machined surface of Ra 0,46 µm.

Published: February 2022

The use of synthetic fibers in composite materials has a negative impact on the environment. One way to reduce this impact is to replace synthetic fibers with natural fibers. A natural fiber that has the potential as a mixed material in the manufacture of composite materials is citronella (Cymbopogon nardus) fiber. This study aims to determine the effect of volume fractions 40%, 50%, 60%, and 70% of citronella fiber with polyester resin matrix BQTN 157 on tensile strength. The process of making composites used the hand lay-up method. The specimen was formed according to the ASTM D3039 standard and the tensile strength of the specimen was tested by using a Universal Testing Machine (UTM). From the results of the study, the maximum tensile strength was found in the fiber volume fraction 70% of 77.35 MPa, the strain is 6.57%, and the modulus of elasticity is 1.177 GPa. This study indicates that fiber volume fraction affects the tensile strength of composite materials. Hence, the manufacture of composite materials which have good strength is influenced by many things such as raw materials, matrices, mixture composition, and methods.

Published: February 2022

Numerous pipeline failures have occurred due to the drastic increase in oil and gas product distribution pipelines over the last three decades. Corrosion is a significant factor in the failure of offshore gas pipelines. It is necessary to maintain the integrity of the offshore transmission system, one of which is the riser, for the product to be adequately distributed. The purpose of this study is to ensure the riser's reliability by conducting a risk assessment of the probability and consequences of equipment failure, mitigating the impact of failure risk, and developing a more optimal inspection plan. The API 5L Grade X60 gas riser pipe is the subject of this study. The quantitative Risk-Based Inspection (RBI) technique was used in 2016 following the API 581 standard. This quantitative approach is founded on a numerical value model constructed using validated operational data and inspection results. The risk assessment indicates that the gas riser pipelines will have a high-risk level (5D) for the splash zone segment and a medium-risk level (2D) for the above-and below-water segments. The recommended inspection plan for the gas riser pipeline is one year after the risk-based inspection assessment.

Published: February 2022

The goal of this research is to evaluate the efficacy and practicality of installing a ground source heat pump (GSHP) with an air source heat pump (ASHP) in a residential setting. The results of this comparison were obtained by monitoring each of the systems in two almost identical residences in Perth, Western Australia. There is an open-loop groundwater system in the previous home. Each residence has one family whose air conditioning system has its own set of operational needs. The cooling capacity supplied and coefficient of performance (COP) as a function of seasonal changes in ambient temperatures were determined using data gathered from both residences over a two-year period. For both heating and cooling, the GSHP system COP was found to be greater than that of the ASHP system. Furthermore, these two performance measures were independent of ambient circumstances in the former, but they exhibit a noticeable ambient dependent trend in the latter. The GSHP had an average COP of 4.0 for heating, regardless of external conditions, while the ASHP COP ranged from 2.0 to 3.0. Conversely, the GSHP had an average COP of 3.2 for cooling, whereas the ASHP COP ranged from 1.4 to 2.9. It is found that GSHPs result in significant operational cost reductions and a significant decrease in greenhouse gas emissions when a borewell is part of a home.
Learning Arabic Language by Analyzing the Linguistic Expressions in the Verses of Surah al-Fatikhah l Ta’allum al-Lugah al-‘Arabiyyah min Khilali Tahlil al-Ta’birat al-Lugawiyyah fi Ayati Surah al-Fatikhah
Authors: Setiyawan Agung , Ainin Moh. , Bahruddin Uril , B. Sapar Ahmad Arifin
Published: February 2022

Surah Al-Fatikhah is very important to understand, because this surah is the main surah in the Qur’an which contains several hidden meanings that need to be understood by every Muslim. Surah Al-Fatikhah must be read in every prayer, but several people do not understand its meaning. This paper aimed to reveal the secrets of sentence phrases in the Surah Al-Fatikhah. The research data were obtained from several classical books (tafsir) and several journal articles discussing Surah Al-Fatikhah. The results showed that Surah Al-Fatikhah contains an implicit message which is reflected in 3 main points, namely: (1) the sentence, such as: deleting alif in the bismillah sentence, the use of "al" in the word ‘Hamdu’ and ‘Alamin’ (2) the word choice, such as: the use of the word al-Rahman, al-Rahim, Rabb al-'Alamin, Malik, Yaum al-din , al-Sirat, al-Mustaqim, al-Magdub, and al-Dallin and (3) sentence structure such as: a statement in the form of a sentence with the intention of the command used in the sentence ‘al-Hamdu lillahi Rabbil ‘Alamin, especially an objective in the expression of “Iyyaka Na'budu wa Iyyaka Nasta’in” as in the study of Balagah chapter al-Qasr in Ma'ani, and equating the word “al-Sirat al-Mustaqim” with al-Din al-Ḥaq as in the study of Balagah chapter al-Majaz in Bayan. Therefore, through this research, by understanding the meaning of the message contained in the Surah Al-Fatikhah, it would hopefully help a Muslim become more motivated in performing prayers.
Stylistic of The Qur’an: The Existence of Majaz Mursal I’tibar Ma Kana
Authors: Murdiono Murdiono , Fatoni Ahmad , Sarimov Renat
Published: February 2022

The existence of majaz mursal i'tibar ma kana in the Qur'an has proven the use of majaz style of language in the Qur'an which underlined that the Qur’an cannot be separated from majaz. The study of the Qur'an will cause the ambiguity in meaning and even fatal mistakes if balaghah approach (majaz) is not used. The data of this research were obtained from the Qur'an and the opinions of several Balaghah experts, such as Abu Ubaidah and Az-Zamakhsyary as the source of information in this study. Semantics was also used in this research, which was analyzing the meaning of the verses of the Qur'an which were classified as majaz i'tibar ma kana. The research results showed that there were 12 verses in the Qur'an including majaz mursal i'tibar ma kana which were found in the different verses, such as surah Al-Baqarah verse (2): 234, surah An-nisa verse (4): 2, surah An-nisa verse (4) 12, surah Al-Rahman verse (55): 56, surah Al-Kahfi verse (28): 47, surah Al-Hujarat verse (49): 9, surah: An-Naml verse (27): 87, surah Fussilat verse (41): 21, surah Thaha verse (20): 74, surah Nuh verse (71): 26-2, surah Ad-Dhukhan (44) verse: 47,48 49. So, there must be a meaningful figure of speech (metaphor) in understanding the verses of the Qur'an and there was no ambiguous meaning. Therefore, this study suggested the need to explore the science of balaghah as one of the tools of science in understanding the Qur'an implicitly.

Authors: Langner Tim
Published: February 2022

Friction and wear as important tribological parameters in dry running plastic plain bearings are largely determined by pressure, sliding speed and contact temperature. This paper presents a methodology for evaluating and comparing different thermoplastic materials and their filler packages for use in plain bearings considering these parameters.

Published: February 2022

This study aimed at identifying how the students of natural and social science majors write descriptive text writing based on the usage of process. This study was conducted by applying descriptive qualitative method. The sources of data were taken from natural and social science students’ descriptive text writing. The results of this research showed that the natural science and social science students used types of process differently in writing their descriptive text. The students from natural science used relational process as the dominant type of process in their description. From 150 types of process used in 13 texts, they use 104 relational processes, it’s 69.33%. They tend to use verbs such as ‘be/is/am/are as attributes and identifications, they also tend to use ‘have/has’ which refers to possession. On the other hand, the dominant type of process used in social science students’ descriptive text writing is existential process. From 107 types of process used in 13 texts, 50 (46.7%) of them are existential process. The findings of the study also showed that the different use of types of process from natural and social science students affected their way in describing object and their way in writing descriptive texts.Keywords: Descriptive, Writing, Process, Natral Science, Social Science

Published: February 2022

Phase transition between drugs with polymorphisms needs attention due to unconscious changes in quality. Valsartan (VAL) is a drug model with polymorphic events to be studied here. Two polymorphic forms were obtained from recrystallization with various organic solvents such as acetonitrile and n-butyl acetate.  With untreated materials (from the market) were used as a comparison in this study. The phase transition of each polymorph was studied through grinding and humidity variations (RH 75% and 98%) treatment. The polymorph characterization was observed by microscope light polarization (PLM), Fourier Transform Infrared (FTIR), and Powdered X-ray Diffractometer (PXRD). The transition among polymorphic VAL was monitored by PXRD. There were significant differences in morphology, IR spectra, and diffractograms pattern. Found that the untreated VAL was amorphous, whereas the others were in high crystallinity. The polymorph form from n-butyl acetate was a metastable one that transformed easier into stable crystalline (from acetonitrile) than another polymorph.Keywords : Valsartan, Phase transition, Polymorphism, Recrystallization

Subtracting manufacturing technologies have entered that realm of production possibilities which, even a few years ago, could not be directly adapted to direct production conditions. The current machines, i.e. heavy, rigid cutting machines using high spindle speed and high feed speed, allow for manufacturing very thin and relatively long parts for use in the automotive or aerospace industry. In addition, the introduction and implementation of new 70XX aluminium alloys with high strength parameters, as well as monolithic diamond cutting tools for special machining, have had a significant impact on the introduction of high-speed machining (HSM) technologies. The main advantage of the applied manufacturing method is obtaining a very good smoothness and surface roughness, reaching even Sz = 6–10 μm and Sa <3 μm, and about four times faster and more efficient machining compared to conventional machining (for the beam part). Moreover, fixed and repeatable milling process of the HSM method, reduction of operational control, easy assembly of components and increase in the finishing efficiency compared to other methods of plastic processing (forming) are other benefits. The authors present a method using HSM for the manufacturing of aircraft parts, such as the chassis beam at the front of a commuter aircraft. The chassis beam assembly is made of two parts, front and rear, which – through a bolted connection – form a complete element replacing the previous part made using traditional technology, i.e., cavity machining, bending and plastic forming. The implementation of HSM technology eliminates many operations related to the construction of components, assembling the components (riveting) and additional controls during construction and assembly.
