This study aims to determine the existence of local political parties in Aceh in the 2009-2019 legislative elections. The presence of local political parties in Aceh is a the result of the peace conflict between the Free Aceh Movement (GAM) and the Government Republic of Indonesia. The birth of a local political party in Aceh brought considerable influence large in the control of seats in the parliament in Aceh in its first participation in the 2009 legislative elections. However, his presence continues to experience According to him, the decline was in line with the number of votes in the next legislative election. This study aims to measure the existence of local political parties in Aceh in terms of 2009-2019 legislative elections. The research method uses the method qualitative descriptive with research focus on legislative elections at the provincial level Aceh in 2009-2019. The data collection techniques used are: interviews and documentation studies. The results showed that the existence of the party Aceh's local politics continues to decline as the number of votes and local political party seats in the 2014 and 2019 legislative elections when compared to the 2009 legislative elections. The decline in the existence of parties local politics in Aceh is measured from the concept of systemic degree, value identity, degree of autonomy and public knowledge

Sports health quantification method and system implementation based on multiple thermal physiology simulation
Authors: Zhu Yayun , Sharaf Sanaa , Jamal Ali Basel 
Published: December 2021

Abstract
People exercising under high ambient temperature will cause changes in physiological indicators. In order to study the thermal physiological state of the human body, we randomly selected 18 volunteers into the thermal environment exercise group and the room temperature exercise group. Two groups of volunteers performed aerobic exercises in different thermal environments. In the case of exercise performed every 15 min, the volunteers’ hemorheology, physical performance rating (RPE) value and rectal temperature (Tre) were tested. At the same time, we recorded the physiological indicators of the volunteers and simulated the thermal physiology. The results showed that there was a difference in the thermal physiology of the two groups of volunteers, and the hemorheology and the self-strain rating scale were highly correlated in the thermal environment (r=0.839, P<0.01). For this reason, we can conclude that exercising in a hot environment will make people have a heavier heat stress response, and thus render them more likely to undergo muscle fatigue. It is advised that exercising at high temperatures may be avoided as much as possible.

Published: December 2021

Abstract
In order to solve the problem of the traditional gray prediction model (GM) during determination of the accuracy of buildings’ energy savings and its poor fitting of data, the idea of a fractional model based on the traditional first-order one-variable GM(1,1) model is applied. We use the GM–backpropagation (GM-BP) neural network to solve the optimal fractional order and establish a fractional GM(1,1) model based on the GM-BP neural network. Example calculation shows that the fractional GM(1,1) model can improve the prediction accuracy of buildings’ energy savings, and selecting the optimal order can further improve the prediction accuracy and decrease the error level when using the GM-BP neural network. This work shows that the fractional GM(1,1) model based on the GM-BP neural network has an important guiding role in the energy savings of buildings.
Research on a reference signal optimisation algorithm for indoor Bluetooth positioning
Authors: Luo Heng , Hu Xinyu , Zou Youmin , Jing Xinglei , Song Chengyi , Ni Qidong 
Published: December 2021

AbstractGPS has a sharp performance decline in terms of accuracy indoors due to the complex building structure. A combined algorithm, targeting at received signal strength indication (RSSI) calibration optimisation, depending on deep neural network training via input vector Γ and the target output vector Ψ, termed reference signal optimisation algorithm (RSOA) is proposed to improve the positioning accuracy in the indoor Bluetooth positioning networks. Experimental results show that the relative error of the proposed RSOA between the estimated results and the measured ones can reach as low as 0.2%, and the absolute errors can be reduced to 0.13 m at most within 10 m.
The impact of foreign capital inflows on poverty in Vietnam: An empirical investigation
Authors: Musakwa Mercy T. , Odhiambo Nicholas M. , Nyasha Sheilla 
Published: December 2021

Abstract
This study investigates the impact of foreign capital inflows on poverty in Vietnam, using annual time series data from 1990 to 2018. The study was motivated by the need to establish if burgeoning foreign capital inflows in Vietnam can support the poverty alleviation agenda. Foreign direct investment (FDI) and external debt were used as proxies for foreign capital inflows; and infant mortality rate, Human Development Index (HDI) and household consumption expenditure were used as poverty proxies. Using the autoregressive distributed lag (ARDL) approach, the study found foreign direct investment to reduce poverty in the short run and long run when household consumption expenditure was used as a poverty measure. However, the study found FDI to worsen poverty in the short run when infant mortality rate and HDI were used as poverty proxies. The study found external debt to have poverty mitigating effect in the short run regardless of the poverty measure used and in the long run only when household consumption expenditure was used as a poverty measure.
The pre-pandemic role of customer online satisfaction in price determination: evidence from hotel industry
Authors: Palić Irena , Palić Petra , Banić Frane 
Published: December 2021

Abstract
This study examines the importance of online reviews for price determination in the hotel industry in the pre-pandemic period. The research is conducted for Croatian small open economy with a developed tourism sector. The paper fills the gap in existing literature by using multivariate principal component analysis to group various customer satisfaction categories in the hotel industry and assessing the relationship between customer satisfaction and hotel price. The conducted empirical analysis points to a positive statistically significant relationship of guest satisfaction and hotel prices. Moreover, linear regression modelling is conducted separately for four-star and five-star hotels. The estimated impacts are statistically significant and positive, but the effects are twice as strong in five-star hotels then in four-star hotels. The obtained results indicate that hotel star rating impacts the strength of the relationship between hotel prices and guest satisfaction. Recognizing the link between hotel ratings, online reviews and pricing is essential both for hotel managers and customers. Hence, the paper provides valuable conclusions from the aspect of supply and demand side in the hotel industry.

Published: December 2021

Abstract
This research was conducted on the protected area of El-Mergueb at M’sila province. The zone of El-Mergueb is located about 180 km south of the capital Algiers, at an altitude from 550 to 800 m, and is characterised by arid climate. The zone of El-Mergueb has a landscape from the steppe to Alfa that lies just as well in the flat ridges hills that in their slopes and in the top part of the ravines. Alfa tenacissima dominates the most geographical space of El-Mergueb. This study is based on the analysis of the homogenous and heterogeneous facies by the determination of the content of calcium carbonate (CaCO3), active calcium carbonate (ACCE) and gypsum through monitoring these chemical parameters during 3 years: 2017, 2018, 2019. Six soil profiles of 15 soil samples collected in the site of study were studied and several chemical soil properties were considered. These factors included: soil pH, calcium carbonate (CaCO3), active total carbonate (CA), gypsum (CaSO4) and electrical conductivity (EC). Principal component analysis (PCA) was used to identify the variations in soil properties. Results showed that there are significant relationships between some soil factors and two PCA axes. The results thus obtained showed that the content of CaCO3 and CA analysed ranged from average to high. The average of gypsum and salinity was low. Floristic diversity defined 284 species. The data on the chemical characteristics of the soil studied have been the subject of a detailed statistical analysis (PCA). Our database consisted of quantitative variables. The implementation of the PCA to the soils studied showed a major dominance of the limestone in the two stations, which explains the alkaline pH and the low concentration of gypsum. Finally, these types of high total limestone are the most observed in the majority of steppe and arid soils.
The Ecological Interpretation of Unbiased Estimator for the Taxonomic Ratio: Different Approaches for Local and Regional Flora
Authors: Zhukov Olexander , Arabadzhy-Tipenko Ludmila 
Published: December 2021

Abstract
Taxonomic ratio in an ecological context is considered as an indicator of the level of competitive exclusion. In spite of more than a century of discussions on taxonomic ratio, the problem of finding an unbiased estimator for flora characterisation remains unsolved. The traditional form of taxonomic ratio (species/genus or species/families ratio) is biased, which depends on the area of territory for which the floral composition was established. This circumstance makes the taxonomic ratio an inadequate characteristic of the flora. To solve the problem of finding an unbiased estimator for the taxonomic ratio, we have combined two fundamental ecological generalisations. The first is that species that belong to the same genus usually live in similar habitats and have similar morphological features. The struggle for life between species from the same genus is, therefore, more intense than between species from different genera. The second is species–area relationship. We have considered the problem of finding an unbiased taxonomic relationship using the Arrhenius curves to fit species–area relationships. This combination allowed us to find a form of unbiased taxonomic relationship. The example of Cyanophyceae flora shows that this indicator is closely related to a wide range of ecological and biogeographical characteristics of vegetation. The residual of the linear equation of dependence of the logarithm of the number of species on the logarithm of the number of genera is an unbiased indicator of the taxonomic relation, which is independent of the number of genera (or number of families) and the sampling size (or area). An unbiased taxonomic relationship is a characteristic of regional flora, which depends on a wide range of its ecological and biogeographical features.
Environmental Aspect of Population Organisation of Terrestrial Mollusk Brephulopsis cylindrica (Pulmonata, Buliminidae) in Space and Time at a Remediation Territory (Nikopol Manganese ore Basin)
Authors: Kolesnykova Kateryna , Zadorozhna Galina 
Published: December 2021

Abstract
Density variability of a population of the mollusk Brephulopsis cylindrica (Menke, 1828) was studied at a reclaimed site in the Nikopol manganese ore basin. This study was conducted on sod-lithogenic soil on grey-green clay. The samples were collected over 3 years, 3 times a year, on a regular grid. Lexis aggregation index (λ) and geostatistical tools were used to characterise spatial distribution of the mollusks. The correlation between the distribution of B. cylindrica and environmental factors was established using correlation analysis. Valid correlations were identified between distribution of the mollusk and variation of the fraction content in composition of structural aggregates of soil. Also, valid correlations were identified with plant species composition at the reclaimed site.
Writing for the Family Audience
Authors: Varga Zsuzsanna 
Published: December 2021

Abstract

Családi Kör (1860–1880) was the leading Hungarian domestic magazine of the mid-19th period, which, under the editorship of the first Hungarian woman of letters Emília Kánya, played a major role in introducing the domestic readership to contemporary European literature and in discussing the struggle of women’s employment opportunities before a wider public. Critical studies have also suggested that it was edited and published under the influence of the German Gartenlaube (1853–1944), the journal credited with embedding the journal of domestic magazine in the broader regime of 19th century print culture. Based on a close reading of the two magazines’ coverage in its European cultural historical context, this chapter offers an account of the possible connections and affinities between the two periodicals, and argues that the Hungarian magazine was significantly more daring in its politics and more systematic in its pursuit of introducing the local audience to European literary trends and works.
Do Verbal Meanings Have a Radial Organization?
Authors: Dimény Hajnalka 
Published: December 2021

Abstract
The paper presents a cognitive-functional analysis of two Hungarian verbs, eszik ‘eat’ and táplál ‘feed’, with the aim of providing a sample for an exhaustive semantic description of verbal polysemy and of relations between verbal meanings.
The hypothesis of the study was that a radial category description of the internal semantic structure of both verbs is possible. The assumption, however, was not confirmed by the analysis; not all meanings of the verb eszik ‘eat’ can be described as deriving from the prototypical eating situation. Some show cases of conceptual blending, while others have a source domain other than the prototypical eating situation. Nonetheless, many figurative meanings seem to be the result of metaphorical meaning shift trigged by common components we experience in the prototypical eating situation and other perceptions. These common components show resemblance on a schematic base.
Pulmonary tuberculosis diagnosis, differentiation and disease management: A review of radiomics applications
Authors: Du Plessis Tamarisk , Rae William Ian Duncombe , Sathekge Mike Michael 
Published: December 2021

Abstract
Pulmonary tuberculosis is a worldwide epidemic that can only be fought effectively with early and accurate diagnosis and proper disease management. The means of diagnosis and disease management should be easily accessible, cost effective and be readily available in the high tuberculosis burdened countries where it is most needed. Fortunately, the fast development of computer science in recent years has ensured that medical images can accurately be quantified. Radiomics is one such tool that can be used to quantify medical images. This review article focuses on the literature currently available on the application of radiomics explicitly for the purpose of diagnosis, differentiation from other pulmonary diseases and disease management of pulmonary tuberculosis. Despite using a formal search strategy, only five articles could be found on the application of radiomics to pulmonary tuberculosis. In all five articles reviewed, radiomic feature extraction was successfully used to quantify digital medical images for the purpose of comparing, or differentiating, pulmonary tuberculosis from other pulmonary diseases. This demonstrates that the use of radiomics for the purpose of tuberculosis disease management and diagnosis remains a valuable data mining opportunity not yet realised.
Comparison of three methods for reconstructing 3D motion from 2D video recordings for low cost gait analysis systems
Authors: Cygan Szymon , Specyalska Adriana 
Published: December 2021

Abstract

Purpose: The aim of this study was to quantify the accuracy of 3D trajectory reconstructions performed from two planar video recordings, using three different reconstruction methods. Additionally, the recordings were carried out using easily available equipment, like built-in cellphone cameras, making the methods suitable for low-cost applications.

Methods: A setup for 3D motion tracking was constructed and used to acquire 2D video recordings subsequently used to reconstruct the 3D trajectories by 1) merging appropriate coordinates, 2) merging coordinates with proportional scaling, and 3) calculating the 3D position based on markers’ projections on the viewing plane. As experimental verification, two markers moving at a fixed distance of 98.9 cm were used to assess the consistency of results. Next, gait analysis in five volunteers was carried out to quantify the differences resulting from different reconstruction methods.

Results: Quantitative evaluation of the investigated 3D trajectories reconstruction methods showed significant differences between those methods, with the worst reconstruction approach resulting in a maximum error of 50% (standard deviation 13%), while the best resulting in a maximum error of 1% (standard deviation 0.44%). The gait analysis results showed differences in mean angles obtained with each reconstruction method reaching only 2°, which can be attributed to the limited measurement volume.

Conclusions: Reconstructing 3D trajectory from 2D views without accounting for the “perspective error” results in significant reconstruction errors. The third method described in this study enables a significant reduction of this issue. Combined with the proposed setup, it provides a functional, low-cost gait analysis system.
Monte Carlo Calculation of linear attenuation coefficients and photon scattering properties of novel concretes loaded with Osmium, Iridium and Barite nanoparticles

Published: December 2021

Abstract

Introduction: Recent studies have shown that the use of high-density nanoparticles (NPs) in concrete composition improves its radiation shielding properties. In the present study, the linear attenuation coefficients and photon scattering properties of newly developed high-density Nano-concretes have been calculated using the MCNPX Monte Carlo code.

Material and methods: The shielding properties of Nano-concretes containing 10%, 20%, and 30% weight percentage of Osmium, Iridium and Barite NPs (100 nm) as well as ordinary concrete were investigated. The 6 and 18 MV photon beams of Varian Linac and 60
Co photons were used for simulation. Photon scattering flux was calculated for all Nano-concretes with 30 wt% of NPs and ordinary concrete at different angles.

Results: In general, by adding Iridium, Osmium and Barite NPs to ordinary concrete, the linear attenuation coefficients increased. Despite a lower density relative to Iridium and Osmium, Nano-concretes containing Barite exhibited a higher linear attenuation coefficient due to their higher electron density.

Conclusions: The results revealed a dependence between the scattered photon flux and the effective atomic number of Nano-concretes. With increasing the atomic number of fillers, the intensity of the scattered photon flux enlarged. Also, the scattered flux was higher for all types of concretes at 180 degrees relative to other angles.

Abstract

Purpose: This study was conducted to demonstrate the feasibility of X-ray output constancy quality assurance (QA) of a linear accelerator for various gantry angles using the Stealth Chamber.

Methods: The X-ray output constancy of a Varian TrueBeam STx was evaluated under various gantry angles and a 10 × 10 cm2 field size using a Stealth Chamber. Specifically, 10X and 10X-flattening-filter-free beams with dose rates of 600 and 2400 monitor units (MU)/min, respectively, were used. The Stealth Chamber was attached to the gantry head, and irradiation was performed every 45° for gantry angles of 0-315°. To evaluate the variations in the output constancy with respect to the gantry angle, the acquired values were normalized to the value corresponding to a 0° gantry angle. The obtained results were utilized to determine the correction factors for all gantry angles. To verify the correction factors, additional measurements were performed for five days.

Results: The maximum variation in the output constancy measurement relative to the output constancy at a 0° gantry angle was found to be approximately 4.0% for both energy beams at a gantry angle of 180°. Furthermore, the measured values were dependent on the gantry angle. Upon applying the correction factor, the variation in the output constancy with respect to the gantry angle was less than 0.5%.

Conclusions: Output constancy QA using the Stealth Chamber for various gantry angles was found to be feasible with the application of a correction factor.
