"Kunsekuensi Hukuman Mati atas Penggalaran Hari Sabat Menurut Keluaran 31 Dan Implementasinya Bagi Orang Percaya Masa Kini"
Authors: Dewa Ananda Dharmawan Kustia , Panjaitan Firman , Lumingkewas Marthin Steven
Published: June 2021

Hari Sabat merupakan Perjanjian Kekal yang memiliki Arti Menikmati istirahat masuk kedalam perhentian. Allah mengkhususkan hari Sabat berbeda dengan hari-hari lainnya, sebab hari Sabat menjadi momen khusus untuk Allah memberkati serta mengkuduskan semua umatnya. Allah berfirman kepada Musa untuk dikatakan kepada bangsa Israel untuk menjaga hari Sabat, hari Sabat merupakan waktu khusus untuk memaknai mengenai perhentian serta penyegaran kembali atas manusia binatang, hamba bahkan orang asing , pembahasan mengenai hari Sabat ini sangat penting untuk dipelajari sebab Allah mengambil inisiatif untuk melakukan serta menjadikan perintah yang termuat di dalam sepuluh hukum Allah yang dikenal dengan sebutan dekalog (Keluaran 20:4). Tercantumnya perintah keempat dalam dekalog membuktikan bahwa Sabat merupakan hal yang sangat penting dalam kehidupan bangsa Israel, yaitu mengenai penyelenggaraan dan kemahakuasaan Allah yang melatarbelakangi seluruh kehidupan bangsa Israel sebagai budak di Mesir yang harus bekerja tanpa henti.
Word processing difficulty and executive control interactively shape comprehension monitoring in a second language: an eye-tracking study
Authors: Hessel Annina , Schroeder Sascha
Published: June 2021

Successful reading comprehension – especially in a second language (L2) – relies on the ability to monitor one’s comprehension, that is, to notice comprehension breaks and make repairs. Comprehension monitoring may be limited given effortful word processing but may also be supported through active reading. The current study addresses to what extent word processing difficulty reduces adolescents’ ability to monitor their comprehension in their L2, and whether readers can compensate limitations given sufficient executive control. We conducted an eye-tracking experiment in which 34 adolescent L2 learners (aged 13–17 years) read short expository texts containing two within-subject manipulations. First, comprehension monitoring was tested through inconsistencies, for example, when the topic changed from Spanish to Russian vis-à-vis consistent controls. Second, word processing difficulty was altered by inserting either shorter and higher-frequency words such as want, or longer and lower-frequency words such as prefer. We additionally measured participants’ executive control. Outcome variables were reading times on the whole texts and the words manipulated for inconsistency and word processing difficulty. We found evidence of successful moment-to-moment monitoring, as visible in adolescents’ increased rereading of inconsistent compared to consistent information. We also found that adolescents adapted their monitoring differently to word processing difficulty, depending on their executive control: while adolescents with weaker control reduced their monitoring given higher word processing difficulty, adolescents with stronger control monitored their comprehension more (instead of less) on difficult texts. These findings provide insights into how L2 comprehension monitoring arises in the interplay of lower-level processing load and active reading processes.

menurut Gordon Fee mengatakan bahwa kerajaan Allah adalah suatu peristiwa masa depan sekaligus sebagai suatu realitas pada masa kini. Menurut George Eldon Ladd, mengatakan bahwa kerajaan Allah itu adalah pemerintahan tertinggi Allah, namun pemerintahanNya itu terwujud dalam tahapan yang berbeda-beda sepanjang sejarah penebusan, dan manusia dapat masuk kedalam kerajaan Allah melalui beberapa tahap pewujudan dan kemudian mengalami berkat-berkat pemerintahanNya itu dalam kadar-kadar yang berbeda-beda. menurut Abert Schweitzer yang juga dikuti oleh Eldon Ladd dalam bukunya tentang injil kerajaan, dia mengatakan bahwa kerajaan Allah bukanlah kenyataan yang secara rohani atau keadaan yang terjadi sekarang ini, tetapi kerajaan Allah itu merupakan suatu kenyataan yang akan datang dan yang bersifat adikodrati. Sedangkan Grame Goldsworthy dan Donal Guthrie mengatakan bahwa kerajaan Allah itu menunjuk kepada masa yang akan datang, dan perwujudan itu akan lengkap pada masa kerajaan yang akan datang, tetapi sudah diwakili pada masa yang sekarang di dalam jemaat. Dalam injil Matius, seruan pertama tentang kerajaan Allah dimulai oleh Yohanes pembaptis yang menyeruhkan kepada orang-orang Israel pada saat itu untuk bertobat sebab kerajaan sorga sudah dekat (Mat. 3:1-2). Pelayanan Yesus dalam Injil Markus dimulai di Galilea setelah Yohanes ditangkap dalam Markus 1:14-15 di situ ada seruan yang ditulis oleh Markus yang disampaikan oleh Yohanes yang berbunyi waktunya telah genap Kerajaan Allah sudah dekat. Lukas juga memberi penekanan tentang kerajaan Allah yang berbeda dengan penekanan oleh Matius dan Markus di mana Lukas melakukan penekanan tentang aksi atau tindakan Allah tentang pemberitaan tentang Kerajaan Allah. Tetapi disamping itu, Lukas juga sependapat bahwa sebenarnya Kerajaan Allah itu sedang dikerjakan pada masa kini dan akan dinampakkan secara penuh pada masa yang akan datang.Hal-hal yang yang perlu ditekankan dalam kitab Injil sinoptik mengenai Kerajaan Allah di antaranya sebagai berikut : Persamaan dan perbedaan gagasan tentang Kerajaan Allah, Aspek soteriologis Kerajaan Allah, Aspek eklesiologi Kerajaan Allah, Aspek moral etis Kerajaan Allah, peranan Yesus dalam kerajaan Allah.
Flexural strike-slip basins
Authors: Neuharth Derek , Brune Sascha , Glerum Anne , Morley Chris , YUAN XIAOPING , Braun Jean
Published: June 2021

Strike-slip faults are classically associated with pull-apart basins where continental crust is thinned between two laterally offset fault segments. Here we propose a subsidence mechanism to explain the formation of a new type of basin where no substantial segment offset or syn-strike-slip thinning is observed. Such “flexural strike-slip basins” form due to a sediment load creating accommodation space by bending the lithosphere. We use a two-way coupling between the geodynamic code ASPECT and surface processes code FastScape to show that flexural strike-slip basins emerge if sediment is deposited on thin lithosphere close to a strike-slip fault. These conditions were met at the Andaman Basin Central Fault, where seismic reflection data provide evidence of a laterally extensive flexural basin with a depocenter located parallel to the strike-slip fault trace.
Designing staggered platelet composite structure with Gaussian process regression based Bayesian optimization

Published: June 2021

The staggered platelet composite structure, one of the most well-known examples of biomimetics, is inspired by the microstructure of nacre, where stiff mineral platelets are stacked with a small fraction of soft polymer in a brick-and-mortar style. Significant efforts have been made to establish a framework for designing a staggered platelet pattern that achieves an excellent balance of toughness and stiffness. However, because no analytical formula for accurately predicting its toughness is available because of the complexity of the failure mechanism of realistic composites, existing studies have investigated either idealized composites with simplified material properties or realistic composites designed by heuristics. In the present study, we propose a Bayesian optimization framework to design a staggered platelet structure that renders high toughness. Gaussian process regression (GPR) was adopted to model statistically the complex relationship between the shape of the staggered platelet array and the resultant toughness. The Markov chain Monte Carlo algorithm was used to determine the optimal kernel hyperparameter set for the GPR. Starting with 14 initial training data collected with uniaxial tensile tests, a GPR-based Bayesian optimization using the expected improvement (EI) acquisition function was carried out. As a result, it was possible to design a staggered platelet pattern with a toughness 11% higher than that of the best sample in the initial training set, and this improvement was achieved after only three iterations of our optimization cycle. As this optimization framework does not require any material theories and models, this process can be easily adapted and applied to various other material optimization problems based on a limited set of experiments or computational simulations.
Cultural Psychological Processes Underlying Workplace Remuneration in Japanese and European American Contexts
Authors: Uchida Aya , Nakayama Masataka , Uchida Yukiko
Published: June 2021

Japan’s remuneration systems are moving away from seniority-based pay towards individual performance-based pay. We tested how the latter system works within the Japanese cultural context and whether the operation and functioning of the system reflects general psychological tendencies found in Japan. Japanese (Study 1 n = 197; Study 2 n = 235) and European American (Study 1 n = 201; Study 2 n = 186) participants read vignettes that described workplace success centered on a focal employee and included a team. Participants attributed contribution and rewards (financial and status) to a range of agents and factors with graded levels of foci, from the focal employee being the greatest and luck being the least. In general, we found that Japanese participants attributed greater contribution and reward to less focal agents and factors while European American participants attributed greater contribution and reward to more focal agents, in addition to some specific differences between the tasks and reward types. We discuss implications for more nuanced theorizing of the interaction between institutional systems and psychological processes.
Autism and adult attachment: Issues with current measurement practices
Authors: Davis Abi M. B. , Kramer Robin Stewart Samuel
Published: June 2021

Attachment styles in individuals with autism are not well understood, and research into the topic is limited to date. Authors regularly utilise standardised measures to classify attachment in adulthood, and this is the case for research with neurotypical and autistic populations. Here, we argue that there may be fundamental problems with using such measures, developed for neurotypical populations, in order to quantify attachment in those with autism. Crucially, such tools may be unable to differentiate between autistic behaviours and behaviours associated with insecure attachment styles. Furthermore, many studies which have investigated attachment and autism may lack sufficient statistical power due to the use of time-consuming attachment interviews or student populations which typically do not contain sufficient numbers of adults with autism. We argue that it is essential that measures are developed which accurately distinguish between insecure attachment styles and behaviours associated with autism, with the goal of better understanding attachment in those with autism for both parental and romantic relationships.
Who supports affirmative action policies for women and immigrants in recruitment processes? An international survey experiment
Authors: Moehring Katja , Teney Céline
Published: June 2021

Our knowledge of support for affirmative action policies (AAP) and its determinants is mainly restricted to the US context. However, AAP polarise the public debate in Western democracies as they involve favouring a candidate at the cost of others because of group membership. Against this backdrop, we ran a factorial survey experiment in Denmark, France and Germany on the introduction of a hypothetical regulation favouring women and immigrants by equal qualifications in the recruitment process for a managing position. Our data show that support for AAP is significantly larger for women than for immigrants. Moreover, support for AAP for both target groups is much higher in France than in Germany or Denmark. Germans and Danes show similar lower levels of support for AAP for immigrants, while support for AAP for women is higher in Germany than Denmark. We conducted multilevel regression models to investigate the power of several attitudinal factors in explaining these target group and country differences. From these models, we drew two conclusions: First, respondents’ varying level of ethnic and gender prejudice and perceived disadvantage faced by women and immigrants can entirely explain target group differences in support for AAP. Second, the differences between Germany and Denmark in support for AAP for women can be explained by national differences in the level of prejudices and perceived disadvantage of both target groups and attitudes toward state intervention. However, this set of attitudinal variables cannot explain why support for AAP is much higher in France than in Germany and Denmark.

Authors: Pant Amba Datt
Published: June 2021

In muon spin rotation and relaxation (mSR) method, theoretical work using first-principles calculations helps to understand the stopping sites and charge states of muon in the sample materials. To support the mSR measurement on protein and DNA, a systematic first-principles study starting from the constituents of the protein has been performed. In this work, the behavior of muonium (Mu = m+e-, bound state of a muon and an electron which is like a light isotope of H atom with similar chemical properties) in a N-acetylglycine-N-methylamide (AGMA), a part of peptide bond, is presented. It is found that the stopping site of Mu is around O of unsaturated bonds between C and O in the AGMA. Further calculations towards whole protein and DNA will be performed to support mSR studies.

Introduction: Nepal started the first phase of COVID-19 vaccination for frontline healthcare workers in January 2021 with the ChAdOx1 nCoV-19 (COVISHIELD) vaccine. We conducted active surveillance of Adverse Effect Following Immunization (AEFI) after the first dose of the vaccine administered at one of the sentinel sites for vaccination, Patan Academy of Health Sciences (PAHS).
Method:  All the 5591 first dose ‘COVISHIELD’ vaccine recipients between 27 Jan -5 Feb 2021 at PAHS, were approached through phone calls to collect data on AEFI.  Incidence of common AEFIs in different age groups, gender and those with previous history of COVID-19 were analyzed. Presence of any Adverse Events of Special Interest (AESI) were evaluated.
Result: Out of 5591 vaccines recipient, 3991 (71.3%) responded to the phone call and AEFI was noted in 3394 (85.04%) of them. Minor AEFI was seen in 3391 (84.9%), severe Minor AEFI in 1 (0.02%) and Serious AEFI in 2 (0.05%). Out of 807 vaccine recipients with previous history of COVID-19, 709 (87.9%) had AEFI while of the 3184 with no past history of COVID-19, 2685 (84.3%) had AEFI. However, some of the systemic AEFIs were noted more frequently in those with past COVID-19 infection. A total of 1886 (55.6%) took self-medication for symptom relief, 278 (8.2%) took leave from work while 26 (0.76%) visited health facility for the AEFIs.
Conclusion:  Most AEFIs following the first dose of COVISHIELD vaccine were mild and resolved within a few days. Except for one case of anaphylaxis, no other AESI were encountered.
The ‘Vero Cell’ COVID-19 vaccine rollout in Nepal: What we know about the Chinese vaccine development and access?
Authors: Shah Jay Narayan
Published: June 2021

The world has changed dramatically from the impact of the COVID-19. It has impacted the normality of daily life, highlighting the failure of rich and poor nations alike, which is evident from the high number of human lives lost in rich and powerful countries like the USA with total deaths of 32,735,704 and Europe with 43,708,958 until April 24, 2021, as per Worldometer. The COVID-19 pandemic has shown that all of us ‘have and have-not’, no one can escape from the effects of the lockdowns, disruption of normal life including education, businesses, etc. reminding all of us that equitable access to vaccines is the best possible choice not to further exacerbate the challenges because ‘no country is safe until every country is safe’. It is a remarkable scientific achievement that within a year of the identification of the virus, we have COVID-19 vaccines, albeit available mostly in rich countries. The benefit of research is possible only with solidarity, by sharing the available resources, vaccine included, for the control of the ongoing COVID-19 pandemic.

Modern science and technology, including the development and marketing of COVID-19 vaccines, have been focused in the USA and Europe. China joined this club of elites of science following the Chinese FDA approval of Sinopharm (the subsidiary of state-owned China National Pharmaceutical Group- CNPG), first COVID-19 vaccine (inactivated Sars-Cov-2) based on the results of the phase-3 clinical trial in UAE and Bahrain showing up to 86% efficacy of the vaccine in preventing COVID-19.

Detail of trials of Sinopharm inactivated COVID-19 vaccines (Vero Cells) available on two early trials in China (Phase I/II ChiCTR2000031809, enrollment 1,456) and later 4 trials outside China (phase III, NCT04510207 Bahrain, Egypt, Jordan, United Arab Emirates- enrollment of 45,000; ChiCTR2000034780 United Arab Emirates, enrollment of 15,000; NCT04612972 Peru, enrollment of 6,000) show the progress of research and approval in China and UAE.

Published: June 2021

Introduction: Spontaneous abortion (SA) is one of the adverse outcomes during pregnancy, which is a challenge for maternal well-being. The present study aimed to analyze the predictors of SA among reproductive age women.

Method: A hospital-based case-control study was conducted at Patan hospital, Nepal. The consecutive sampling technique was used to select the cases (84) and a purposive sampling technique was used for controls (168) in a 1:2 ratio. Ethical approval was obtained. Data were collected through face to face interviews using a structured questionnaire. Descriptive and inferential statistics (Chi-square, Fisher exact test, and logistic regression) were used for analyzing the data.

Result: We found that previous history of abortion (OR=3.80, 95% CI=1.8-7.70), heavy lifting (OR=20.45, 95% CI =4.48-93.38), emotional disturbance (OR=10.06, 95% CI=1.06-96.96), health problems (fever of unknown cause and urinary tract infection) during pregnancy (OR=16.53, 95% CI=1.90-143.41), coffee intake (OR=0.36, 95% CI=0.20-0.63), unplanned pregnancy (OR=0.10,95% CI=0.04-0.22), preconception counseling/care not received (OR=6.48, 95% CI=2.18-19.21) were the significant predictors of SA among reproductive age women.

Conclusion: Our findings show that the previous history of abortion, heavy lifting, emotional disturbances, health problems, and coffee intake during pregnancy are the significant cause of SA; and preconception counseling and planned pregnancy are protective factors.

The present work re-evaluates the level density parameter a, asymptotic level density parameter aasy, and back-shifted energy parameter E1 within the back-shifted Fermi gas model (BSFG) for the 153Sm nucleus. This reevaluation is based on the experimental nuclear level scheme extracted from the ENSDF library, the average level spacing at the neutron binding energy (D0 value), and the latest updated nuclear level scheme obtained from an experimental gamma cascade experiment, which was performed at the Dalat Nuclear Research Reactor using the thermal neutron beam. The updated values of the BSFG level parameters are: (1) a=18.09±0.25 MeV-1and E1=-0.92±0.07 MeV for the energy-independent level density parameter; and (2) aasy=15.00±0.20 MeV-1and E1=-0.81±0.08 MeV for the energy-dependent level density parameter. It has been found that the total nuclear level densities calculated using these updated parameters agree with the experimental data better than those using parameters taken from the nuclear reference database RIPL-3. These updated parameters are more accurate and reliable than those extracted from RIPL-3 and are, therefore, highly recommended for all the applications hereafter.

Polymers used as insulating materials are increasingly popular in many different fields. In electrical engineering - electronics, polymers are used in high-voltage transmission cables, capacitors, transformers, or as part of an embedded system in the IGBT module thanks to its superior thermal and electrical insulation properties. One of the disadvantages of polymers is the possible accumulation of space charge in the material volume for a long time, leading to an increase in the electric field compared to the original design value. Charge transport models in polymer materials have been increasingly developed to predict the conduction mechanisms under thermal-electrical stress. In this study, from a finite volume method (FVM), the authors developed a charge transport model in low density polyethylene (LDPE) based on the finite element method (FEM). The simulation results of this model are also compared to experimental results and to the FVM model under different electric fields for LDPE.

Dispersion of nanoclay in Epikote 828 resin is conducted by closed mixing of the liquid composition, mechanical mixing combined with ultrasonic vibration to form masterbatch; meanwhile, nanoclay dispersion in bitumen is processed by melted bitumen mixing. XRD techniques were used to determine the basal d-spacing of nanoclay. The dispersion was performed in Brabender mixer at temperature 40oC, speed 50 rpm, an Epikot/I30E=100/80 masterbatch provided the best dispersion with d001=33.818 Å. After mechanical mixing, an Epikote 828 composition with 4% I30E was sonicated for 5, 10, and 20 minutes. The value d001=41.65 Å achieved after 10 minutes of sonication was deemed optimal. Dispersion of 4% I30E in melted bitumen at 120, 130, 140, 150, and 160oC after 2h reached d001=49.5916 Å for the sample processed at 120oC. At high temperatures, penetration and delamination of bitumen were better than those of Epikote 828 despite the lower molecular weight of Epikote.

Drought-tolerant rice varieties are one of the best choices to avoid the effects of drought. A Randomized Complete Block Design (RCBD) with three replications was used for the experiment. 12 seasonal rice were tested under artificial drought conditions. The criteria were assessed through the morphology, root anatomical structure, and stomatal leaves that were suitable for the drought environment. The results showed that 3 seasonal rice were well adapted to this condition.Sophinh had the smallest density and area of stomata (529.3 stomata/mm2 and 88.6 μm2 respectively), they helped reduce water loss. Xuong ga do had the highest ratio of deep roots 58.7% which could increase the ability to take water from the deep soil layer. Bang nau had a thick root diameter of 876.3 μm and a stele root area of 54.4x103 μm2 containing a high number and more areas of late metaxylems (5.6 and 12x103 μm2 respectively). These factors helped increase water flux from root to shoot. Correlation among the density of stomata, number of roots, and the number of late metaxylem were negative while correlation among diameter of roots, number of late metaxylem, and total areas of late metaxylem were positive. These results were useful for developing drought-tolerant rice varieties.

Nano silica of size 20-50 nm prepared by the sol-gel method was used to test the effect on the growth of Bacillus subtilis GB03 in in vitro bioassay and evaluate the effectiveness of integrating nano silica and B. subtilis GB03 for the growth of melon crop (Cucumis melo). The results showed that nanosilica at a concentration of 10 μg/ml had a good effect on the growth of B. subtilis GB03. In the in vivo experiment, not only the incident of silica nanoparticles adhering to the bacterial surface but also bacterial invasion and penetration on the roots were observed. Besides, the mixture of B. subtilis GB03-nano silica at 10 μg/ml also showed a good impact on the rate and speed of germination, the development of the roots, growth time, height, and branching of the melon plant. The study suggested the development of natural-derived nano silica-endophytic bacteria preparations to replace synthetic chemical pesticides used in agriculture.

QTL9 is a new potential quantitative trait locus related to rice panicle structure, identified through a GWAS analysis of Vietnamese local rice panel. To validate the QTL9, a biparental population was developed using the low branching (G6) and the high branching (G189) accessions from two haplotypes characterised by a contrasting phenotype for the secondary branch number and spikelet number traits. In parallel, using Gene capture technology combined with new generation sequencing identified 1,002 genetic variants in the QTL9 region between two parents, of which 12 SNPs were found in the cleavage site of 5 restriction enzyme. In this study, 12 primer pairs were tested to amplify the CAPS markers, based on the 12 SNPs, in order to be applied to select homozygous F2 lines over the QTL9 region for both haplotypes. 4 CAPS markers were selected distributing over the QTL9 region and displaying polymorphism between two parents. 275 F2plants were genotyped using 3 CAPS markers leading to the selection of 74 homozygotes plants over the QTL9region for haplotype 1, 66 homozygotes plants over the QTL9 region for haplotype 2, and 153 heterozygous plants. Homozygous lines will be used to develop the F3population, phenotyping of two F3 haplotypes will lead to discovering the role of QTL9 related to rice panicle structure.

In Campos grasslands, the production of forage and its variability are driven by the amount of rainfall. In this context, stockpiling forage from spring to summer is a useful tool to maintain the feed supply for livestock, but so far it has not been developed due to the lack of information for farmers decision-making. In this paper we evaluated the response of pasture production to spring grazing deferment in a shallow basaltic grassland in 12 combinations of lime (0 and 1500 kg ha-1 of CaMg(CO3)2), phosphorus (0 and 90 kg ha-1 of P2O5) and nitrogen (0, 75, 150, and 300 kg ha-1 of N, except in the upper two N levels that were evaluated only with lime) addition. Forage accumulation, sward height and nitrogen nutrition index (NNI) were evaluated every 15 days during 75 days. Both sward height and available forage mass increased linearly with the deferment time. The lime application did not affect the forage accumulation rate, while the single nitrogen and phosphorus addition only showed a slight positive effect, however the combined addition of N-P fertilization tripled the forage production. Nitrogen fertilization improved the NNI and was further enhanced by the combined application of N and P. Our results suggest that the capacity of shallow basaltic grasslands to accumulate deferred forage is co-limited by N and P availability.

Information and communication technology has consistently changed the culture and way of seeing people in traveling. Tourism activities that were previously only a complementary priority are now turning into a top priority for the community. The high interest in traveling stimulates the creativity of various groups of people to explore the potential of their area to become a tourist destination. Geographical, culinary, handicraft and cultural potentials are growing in various regions. Pasar Setu Minggu (Semi) Kaki Langit is one of the tourist destinations developed by the Mangunan community by exploring regional potential and traditional culinary wealth. The development is quite good and able to lift the people’s economy. However, after Covid-19 occurred, for four months there were no visits at all. Market facilities that have no activity have become a little neglected. However, after signs of community tourism activity improved, residents were excited to improve tourist facilities based on Covid-19. The change in the concept of tourism based on Covid-19 certainly needs to be communicated to consumers. Information and communication technology and delivering interesting content are expected to be able to accelerate the recovery of Kaki Langit tourism. This community service aims to help restore Kaki Langit tourist destinations through packaging of local products.

The development of information and communication technology has led to the transformation of traditional business practices in all sectors of the economy. Information and communication technologies in the field of tourism represent a generator of change and drivers of development, by enabling the creation and retention of a large number of jobs, business opportunities and significant added value. Given the well-recognized value of the information and communication technologies in tourism, this chapter sought to identify the countries with the highest level of travel and tourism ICT readiness. Therefore, a two-step analysis was applied where in the first step the weights were determined using two approaches, PCA and SWARA. In the second step, using multicriteria analysis, the evaluation of ICT readiness of European countries was performed. The results indicate that the application of weight coefficients determined by different approaches in the same multicriteria method leads to moderate rank inversion.

Since its expansion at the beginning of the 20th century, tourism has shown its strength and importance. Tourism is a link between several economic sectors, thanks to its accumulated development potential. One of the main goals of business entities from the financial point of view is to achieve profit. The second is the maximize the value of the company, which can be affected by the achievement of profit. Companies operating in the field of tourism in the Slovak Republic are no exception. The chapter deals with the analysis of their equity, including its individual items with an emphasis on the going concern. Using Pearson’s correlation coefficient, we identify the relationship between equity and its individual items. The aim of the chapter is, based on indebtedness indicators, specifically total indebtedness and the degree of self-financing to assess the adequacy of own resources needed to finance its activities in this sector in the Slovak Republic, while marginally analyzing the impact of COVID-19 on the tourism sector in Slovakia.
