This study aims to determine and describe the Performance Structure of Kuda Lumping in Kampung Lapai Village, Nanggalo District, Padang.This research belongs to a qualitative research. The research instruments used were the researcher it self, writing tools, and cellphone cameras. The object of this research was Kuda Lumping Brandon in Kampung Lapai Village, Nanggalo District, Padang.The results show that Kuda Lumping has a performance structure which cannot be removed or reversed from beginning to end. In the performance process, there must be several important people or instruments such as a handler, offerings, players, and other instruments such as musical instruments, properties, and a team which can help the handler in the process of Kuda Lumping show. Judging from the results of observations regarding the structure of the show, Kuda Lumping Brandon has a clear performance structure. It contains elements which are mutually related one to another. For instance, in term musical elements, if ini the lumping horse show there is no music, it will affect the dancer, this also related to the existence of a trance scene because each musical stroke will affect the movements of the dancer whose musical trance plays an important role in every lumping horse show without music, it will not have a beautiful aesthetic value.

ABSTRACTThe objectives of this study were to explain whether : (1) the students’ achievement in listening comprehension taught by using video was significantly higher than that taught by audio (2) the students’ achievement taught to high motivation significantly was higher than that to students’ low motivation? (3) therewas any significant interaction among teaching media (video and audio) and motivation in listening comprehension achievement. The research design is experimental research by using factorial design 2x2. There were 72 students from MAS YMPI Kota Tanjungbalai as sample of this research. The students were divided into two groups. The first group was treated by using Audio and the second group was treated by using Video. Students’ achievement in listening comprehension was measured by using multiple choice tests. The data were analyzed by applying Two-Ways ANOVA. The result revealed that (1) students’ listening comprehension achievement taught by using video wassignificantly higher than that taught by using audio with Fobservedwas higher than that Ftable at level significance α = 0.05 (Fobserved = 155.7>Ftable = 3.98). (2) There was significant difference of students achievement in listening comprehension with high motivation was taught by using video was higher than that low motivation by using audio with Fobserved is higher than Ftable at the level significance α = 0.05 (Fobserved = 93.4>Ftable = 3.98). (3) There was significance interaction among media (audio and video) and students’ motivation on students’ achievement in listening comprehension with Fobservedwas lower than Ftable at level significance α = 0.05 (Fobserved = 1.2 <Ftable = 3.98). Thus, media (audio and video) and students’ motivation significantly affect the students’ achievement in listening comprehension. Keywords: Audio, Video, Motivation, Listening Comprehension

Introduction
Previous cardiovascular disease (CVD) and myocardial involvement are common in coronavirus disease-19 (COVID-19). We investigated relationships between CVD, cardiac biomarkers and outcome in COVID-19.

Methods
We analyzed n = 252 patients from a multicenter study and provided comparison according to the presence or absence of underlying CVD. Cardiac biomarkers high-sensitivity Troponin [upper reference of normality (URN) 35 pg/ml for Troponin I and 14 pg/ml for Troponin T] and natriuretic peptides (Nt-pro-B-type natriuretic peptide, URN 300 pg/ml and B-type natriuretic peptide, URN 100 pg/ml) were both available in n = 136.

Results
Mean age was 69 ± 16 years (56% men, 31% with previous CVD). Raised hs-Troponin and natriuretic peptides were detected in 36 and 50% of the cases respectively. Age, chronic obstructive pulmonary disease, hemoglobin, hs-Troponin and natriuretic peptides were independently associated with underlying CVD (P < 0.05 for all). Compared with the normal biomarkers subgroups, patients with isolated hs-Troponin elevation had higher in-hospital mortality (31 vs. 4%, P < 0.05), similar CVD prevalence (15 vs. 11%) and trend towards higher D-dimer (930 vs. 397 ng/ml, P = 0.140). Patients with both biomarkers elevated had higher age, D-dimer, CVD and in-hospital mortality prevalence compared with other subgroups (all P < 0.05 for trend). Outcome analysis revealed previous CVD [model 1: OR 2.72 (95% CI 1.14–6.49), P = 0.024. model 2: OR 2.65 (95% CI 1.05–6.71), P = 0.039], hs-Troponin (log10) [OR 2.61 (95% CI 1.21–5.66), P = 0.015] and natriuretic peptides (log10) [OR 5.84 (95%CI 2.43–14), P < 0.001] to be independently associated with in-hospital mortality.

Conclusion
In our population, previous CVD was part of a vulnerable phenotype including older age, comorbidities, increased cardiac biomarkers and worse prognosis. Patients with isolated increase in hs-Troponin suffered higher mortality rates despite low prevalence of CVD, possibly explained by higher COVID-19-related systemic involvement.
Pandemic as an impulse for the development of sustainable tourism along the Danube river
Authors: Vitková Ľubica , Štrbíková Dominika 
Published: September 2021

Abstract
The coronavirus (COVID-19) pandemic is a challenge to the world – primarily from the medical and economic point of view – but also to the search for new forms of tourism and the urban environment. Prior to mass vaccination, the main strategy to manage a pandemic were non-pharmaceutical interventions. Global travel restrictions and "home" regulations have caused the most serious disruption to the global economy since World War II. International travel bans affecting more than 90% of the world's population, widespread restrictions on public gatherings and community mobility have severely curtailed tourism since March 2020. Evidence of impacts on air transport, shipping and accommodation has been devastating. World tourism fell by 35-90% in 2020 compared to 2019. Yet, there are differences between countries. Tourism is particularly sensitive to measures against pandemics due to limited mobility and social distances. The paper compares the effects of COVID-19 with previous epidemics, pandemics or other types of global crises. It examines how a pandemic can change the society, economy, tourism and its projection into the territory. It discusses why COVID-19 is analogous to the ongoing climate crisis and why the mass growth tourism model needs to be questioned. The method to improve responsible access to our planet and ensure safe recreation for its population is sustainable tourism. The Danube Region has a great potential for the development of sustainable tourism in Slovakia with its transport accessibility, connection to the Danube River and through it to the surrounding areas. However, the potential of the region lies mainly in its hitherto underused cultural and natural conditions, as well as in the exploitation of the abilities of its inhabitants. The presented study analyzes the mentioned conditions and points out the possibilities of their development.

Abstract
The accumulation potency of zinc nanoparticles in Nile tilapia (Oreochromis niloticus) was previously studied but their impacts on proximate chemical composition in muscle tissue by describing the dose-dependent accumulation and the protective role of vitamins (E + C), have not been investigated. Therefore, this study was carried out to assess the protective role of vitamins (E + C) on Zn accumulation in muscle and gill tissues of O. niloticus exposed to three sub-lethal concentrations (1/8 LC50, 1/4 LC50, and 1/2 LC50) of zinc oxide nanoparticles (ZnO NPs) compared to zinc oxide bulk particles (ZnO BPs) as well as their effects on the induced chemical composition alterations for different experimental periods (7, 14, 21, and 28 days). The data displayed that fish exposed to the different sub-lethal concentrations of ZnO NPs or ZnO BPs have a significant increase (P<0.05) in Zn ions accumulation in muscle and gill tissues compared to control group but Zn was accumulated in gill tissue higher than muscle tissue at all exposure periods. Also, Zn accumulation was higher in fish tissues exposed to ZnO NPs than ZnO BPs. On the other hand, groups supplemented with vitamins (E + C) showed a significant decreasing (P<0.05) in accumulated Zn levels compared to groups without supplementation. The values of these supplemented groups returned to similar levels established in the control at low concentrations but still higher than control at the high concentrations. Furthermore, the results showed that moisture and ash content slightly increased while protein and fat decreased in fish exposed to ZnO NPs or ZnO BPs compared to control group. In conclusion, the findings supported that a combination of vitamins (E + C) reduced Zn accumulation and ameliorated chemical composition alterations in O. niloticus fish.

Abstract
The study objective was to evaluate the impact of different contributions of pea (Pisum sativum) cultivar Hubal and blue lupin (Lupinus angustifolius) cultivar Regent on the level of selected bioactive substances in pork meat. One hundred three cross-breed piglets: ♀ (Landrace × Yorkshire) × ♂ Duroc were used. Two experiments were performed, in which pea seeds (experiment I: E1 – 5.0% pea seeds; E2 – 10.0% pea seeds; E3 – 15.0% pea seeds; E4 – 17.5% pea seeds) and blue lupin seeds (experiment II; D1 – 5.0% blue lupin seeds; D2 – 10.0% blue lupin seeds; D3 – 15.0% blue lupin seeds D4 – 17.5% blue lupin seeds) were used instead of genetically modified soybean meal (SBM-GM). In each of the experiments 50 animals were divided into 5 groups (control – C, and four experimentals), placed in group pens, each for 10 individuals (sex ratio barrows : gilts – 1:1). The animals were weighed and tagged before the experiments. The initial body weight of the pigs at experiment I and II commencement was: 26.7 and 33.5 kg, and at the end of the experiments: 122.0 and 124.0, respectively. In the first experiment (progressive pea “seeds” contribution) the concentration of carnosine was shown to be higher in E4 than E3 and C by 47.3% and 94.2%, respectively. In comparison with group C, the Q10 coenzyme content in groups E1, E2, E3 and E4 was lower by 40.9%, 56.8%, 40.9% and 65.9% respectively. In the experiment II (progressive lupin “seeds” contribution) increased content of all of the investigated bioactive substances was recorded in groups D1-D3 vs C. Significant differences between groups C, D2, D4 for taurine (P≤0.05; P≤0.01) and creatine (P≤0.05) have been recorded. The content of bioactive substances in the longissimus lumborum muscle was significantly influenced by legumes, which increased the level of bioactive components of protein fraction. Therefore, it can be concluded that pea (Pisum sativum) cultivar Hubal and blue lupin (Lupinus angustifolius) cultivar Regent are an alternative to SBM-GM, increasing the nutritional value of pork meat.
Output Losses from Currency Crises and the Role of Central Bank
Authors: Yazdani Mahdi , Nikzad Mohammad 
Published: September 2021

Abstract
Generally, one of the important issues related to currency crises is the output losses caused by these phenomena. In this study, determinants of output losses and particularly the role of the central bank will be evaluated during currency crises. Moreover, the paper tries to investigate the roles of macroeconomic variables and also monetary, fiscal and exchange rate policies on the output losses during currency crises. In this regard, an econometric model with panel data has been used for emerging market countries during 1980-2016. The results show that currency crises accruing have a positive and significant effect on output losses. While the successful defence of central bank has had the negative effects on the output losses, but it is positive for the unsuccessful defence and the non-intervention or immediate depreciation. However, the role of the macroeconomic condition is important where total foreign reserves can be considered as a buffer against the output losses, while inflation and deviation of the real exchange rate from its trend have had positive effects on the output losses. Finally, the output losses can be reduced by an active monetary, fiscal and exchange rate policies.
Academic Reading Format Preferences and Behaviours: An Exploratory Study amongst Undergraduate African University Students
Authors: Enakrire Rexwhite Tega , Mostert Janneke 
Published: September 2021

To be academically successful a university student is required to read extensively on topics related to his or her field of study. The current proliferation and availability of electronic academic reading materials on various online platforms require academic staff to gain an understanding of their impact on the format preference and reading behaviour of students. Knowledge of emerging trends can guide academic staff to provide reading materials in the format best suited to the reading preferences of students. To establish the current format and reading behaviour trends a multiple case study design was employed targeting undergraduate students from the University of Zululand, South Africa and Delta State University, Nigeria. A questionnaire was used to collect data from a sample of 237 students. A combined return rate of 69.9% was achieved. The findings revealed a strong preference for reading textbooks in printed format. The preference for reading documents in electronic or print format was influenced by factors such as the length of the document, the purpose of reading the document, and whether the document is written in the student’s native language or not. External factors such as access to electronic gadgets and data, and the cost thereof, as well as peer pressure also influenced preference for a specific format. The study recommends that regular surveys should be conducted in academic institutions to keep track of current and changing trends in the format preferences and resultant reading behaviour of the students to enable academics to adapt their prescribed reading materials to a format best suited to the students’ preferences.

Published: September 2021

Background:
Cerebellar mutism (CM) is defined as the lack of speech production, despite an intact state of consciousness and cognitive function, that happens secondary to a cerebellar insult. To the best of our knowledge, only five cases have thus far been described in the English literature. In this paper, we report the sixth incidence overall, which is also the first case of a CM associated with penetrating head injury. The relevant literature is reviewed and analyzed, our current knowledge of the neuroanatomical and functional relations is summarized, and potential future research endeavors are indicated.

Case Description:
An 8-year-old girl was transferred to our hospital having had fallen on a rod that penetrated her neck behind the ear. An urgent computed tomography scan of the head revealed a right cerebellar contusion with surrounding edema. Three days later, she became mute but was still obeying commands. Repeat imaging showed a resolving cerebellar contusion with increased edema and mass effect. By day 9, she had uttered a few words. At 1-month follow-up, the child had regained normal speech.

Conclusion:
Posttraumatic CM is a rare and probably underreported condition with only six documented cases to date. Although it may well be on the same spectrum as postoperative CM, further understanding of the exact mechanism, clinical course, and prognosis of this entity is bound to significantly improve the recovery and quality of life of head trauma patients.
Recommencement of anticoagulation/antiplatelet therapy following non-operative management of a Chronic Subdural Hematoma – Is there an optimal time frame?
Authors: Shah Savan , George K. Joshi 
Published: September 2021

Background:
There is no consensus among clinicians regarding recommencement of antithrombotic agents following conservative management of a Chronic Subdural Hematoma (cSDH). Thus, the primary objective of this study was to determine the most commonly recommended interval and whether the data reveal a general consensus that should be adopted.

Methods:
A retrospective analysis of Salford Royal Foundation Trust’s Neurosurgical referral database for patients referred with a cSDH between March 2017 and March 2020 was carried out. Patients were sorted by whether they were on blood-thinning medications.

Results:
Over the 3-year period, there were a total of 1220 referral and 1099 patients. 502 (41.14%) of these referrals and 479 (43.59%) patients were on one more blood thinning agent. Of these patients 221 (46.13%) conservative management, there was a clear male predominance (M: F ≈ 2.5:1) in this cohort. 2 weeks was the most commonly advised time-frame (n = 76, 36.36%) to withhold. Of the 234 referrals, there were 13 (5.88%) re-referrals in total. Crucially, there was no significant difference in reaccumulation rates between patients asked to withhold their blood thinners for 2 weeks versus those asked to stop for longer than 2 weeks (P = 0.57).

Conclusion:
For the majority of bleeds, there is no clear benefit from asking patients to withhold their anticoagulant/antiplatelet for longer than 2 weeks. In cases, where it is deemed appropriate to stop for longer than 2 weeks, clear instructions should be provided and documented along with reasons behind the decision.
Utility of O-arm navigation for atlantoaxial fusion with Bow Hunter’s syndrome
Authors: Shigekawa Seiji , Inoue Akihiro , Tagawa Masahiko , Kohno Daisuke , Kunieda Takeharu 
Published: September 2021

Background:
In spinal instrumentation surgery, safe and accurate placement of implants such as lateral mass screws and pedicle screws should be a top priority. In particular, C2 stabilization can be challenging due to the complex anatomy of the upper cervical spine. Here, we present a case of Bow Hunter’s syndrome (BHS) successfully treated by an O-arm-navigated atlantoaxial fusion.

Case Description:
A 53-year-old male presented with a 10-year history of repeated episodes of transient loss of consciousness following neck rotation to the right. Although the unenhanced magnetic resonance imaging showed no pathological findings, the MR angiogram with dynamic digital subtraction angiography revealed a dominant left vertebral artery (VA) and hypoplasia of the right VA. The latter study further demonstrated significant flow reduction in the left VA at the C1-C2 level when the head was rotated toward the right. With these findings of BHS, a C1-C2 decompression/posterior fusion using the Goel-Harms technique with O-arm navigation was performed. The postoperative cervical X-rays showed adequate decompression/fixation, and symptoms resolved without sequelae.

Conclusion:
C1-C2 posterior decompression/fusion effectively treats BHS, and is more safely/effectively performed utilizing O-arm navigation for C1-C2 screw placement.
