Algebra in Swedish mathematics curricula (1930-2000)
Authors: Prytz Johan
Published: November 2020

This paper can be seen as an overview concerning algebra in the Swedish mathematics curricula in the period of 1930-2000; the prescribed content of the algebra teaching is described and the basic ideas about how to teach algebra. The analysis is, however, focused on how the syllabi and commentary materials gave teachers more or less freedom to plan and carry out their teaching. The analysis is based on Basil Bernstein’s concepts of classification and framing.
Shaping analytic geometry as a secondary school subject. A comparative study

Our analysis concentrates on textbooks from the late 19th century until the middle of the 20th century known to be used in schools. Keywords: history, analytic geometry, textbooks, mathematics education
Descriptive geometry in middle school mathematics teaching in Japan (1905-1946)
Authors: Kataoka Kei
Published: November 2020

Teaching of descriptive geometry began in 18th-century France and became widespread in tertiary and secondary education worldwide throughout the 19th century. Until the 20th century, educators often described two aims of descriptive geometry – technical education and mathematics education. In Japan, descriptive geometry was introduced into engineering and artistic higher education after the Meiji Restoration of 1868. Descriptive geometry became part of the general secondary school curriculum in the 1880s, but it had been taught under the auspices of arts and crafts education rather than mathematics. In the early 20th century, Japanese mathematics educators began to focus on descriptive geometry as a way to reform solid geometry. When Japan’s secondary school curriculum was revised in 1942, descriptive geometry was included in solid geometry and mathematics for the first time. Although this curriculum lasted only until 1946, it was the fruit of many educators’ labors and is worthy of examination. This paper examines several books and documents from the early 20th-century Japan and shows that there was a technical, mathematics-oriented debate about the aim of descriptive geometry teaching as seen in Europe. Keywords: descriptive geometry, solid geometry, secondary school, middle school, Nobutaro Nabeshima, Minoru Kuroda
The history of Tatar mathematics education
Authors: Safuanov Ildar
Published: November 2020

The history of mathematics education of the Tatar nation from Medieval to modern times is described. Three stages of the development of mathematical education in Tatar schools are traced: 1) Mathematical education in Arabic language (up to the last decades of the 19th century); 2) Mathematical education in old Turk-Tatar language with terminology mostly in Arabic (second half of 19th century and the beginning of 20th century); 3) Mathematical education in modern Tatar language (from the beginning of the 20th century, especially after the October revolution). Keywords: history, mathematics education, Tatar language
Sulaymân al-Harâ’irî (1824-1877): his attempts to reconcile the Islamic civilization with modern science and mathematics education
Authors: Abdeljaouad Mahdi , Ageron Pierre
Published: November 2020

Who was Sulaymân al-Harâ’irî? Little is known about this enigmatic and controversial scholar. Born in Tunis in 1824, he settled in Paris in 1856 and died there in 1877. His unpublished manuscripts contain many translations into Arabic of French books, several of which are pertinent to mathematics. He translated arithmetic textbooks by Hippolyte Vernier, a surveying textbook by G. Frédéric Olivier and La Lande’s survey on uses of logarithms. He also drew up the plan for a comprehensive treatise on practical geometry, thus apparently laying the foundation for a Euro-Islamic hybrid mathematical knowledge. Keywords: Tunisia, Arabic language, translation, hybridization, arithmetic, logarithms, practical geometry
From experimental to theoretical geometry in new pedagogical movements at the turn of the 19th and 20th centuries (1872-1906)
Authors: Barbin Évelyne
Published: November 2020

There exist many historical works on the new pedagogical movements in the beginning of the 20th century, at the level of one country and at the international level also. Our purpose is to focus on teaching of geometry with comparing situations in four countries: United Kingdom, France, Germany and United States. We show that, behind the agreements, there are deep differences in relation with questions posed by geometrical teaching. We use two kinds of materials, discussions and textbooks, and we specially examine the questions on parallels definitions and their introduction in teaching. Keywords: laboratory method, concrete geometry, experimental geometry, intuitive geometry, practical geometry, rational geometry, Émile Borel, Carlo Bourlet, John Dewey, George Halsted, Julius Henrici, Adelia Hornbrook, Jules Houël, Charles Méray, Eliakim Moore, John Perry, Peter Treutlein.
Georges Cuisenaire’s numbers in colour. A teaching aid that survived the 1950s
Authors: De Bock Dirk
Published: November 2020

In 1952, a Belgian primary school teacher, Georges Cuisenaire, published Les nombres en couleurs, a booklet in which the author describes his invention and explains a corresponding method for teaching elementary arithmetic. Cuisenaire materialized the numbers from one to ten by means of rods of corresponding lengths and in different colours. The rods provided a concrete tool for exploring and gaining insight in basic concepts and skills, such as the four basic operations, finding divisors and multiples, working with fractions, the decimal system, arithmetic sequences, and area and volume calculation. From the mid-1950s, with the support of Caleb Gattegno, the Cuisenaire rods broke through worldwide. In subsequent years, empirical research into the effectiveness of the Cuisenaire’s method was initiated and in several countries Cuisenaire Associations were founded. In the late 1960s and 1970s, a number of attempts were made to use the material for the teaching of typical modern mathematics contents to (very) young children, but the use of the rods in this context was sometimes far-fetched and did not break through.

The research focus of the publication is the problem of preserving the blood of the operated patient. The variety of blood preservation methods shows the multidisciplinary nature of the problem and the importance of well-coordinated teamwork of busy doctors. For more than 20 years, surgical, anesthetic, transfusion technologies of blood saving have been used mainly in cardiac surgery patients. The use of a complex of blood-saving technologies allows you to reduce the amount of blood loss and the consumption of donor blood components. Over 7 years in cardiac surgery, the number of recipients of donor hemocomponents decreased by 41% (erythrovesue) and 61% (FFP). Autologous plasma is 68-78% of the total volume transfused to cardiac patients. 50% of patients operated on the ascending aorta do not need a blood transfusion. Blood loss during extensive liver resections has decreased three times in 10 years and does not require allogeneic blood transfusions. An adequate multidisciplinary approach to solving the problem of blood conservation can improve the results of surgical treatment of patients.

Primary health care is a highly effective and efficient way to tackle the root causes and risks of poor health status, and to address emerging problems that threaten future health and well-being. Goal: Develop a model for predicting the need for general practitioners (GPs) until 2030, taking into account various input data in the equations describing the movement of labor resources in the form of “flows” and “ stocks “ using the method of system dynamics. Methods: The model was built using the Any Logic program, based on information about the availability of primary health care doctors, demographic data and the general prevalence of diseases in the population. Three scenarios were considered to predict the need for general practitioners. The base year was 2018, the forecast was carried out until 2030. Results: All of three scenarios indicate that with the current number of graduated GPs, the shortage of primary care physicians will be exacerbated. In general, the shortage can reach more than two thousand. Conclusion: Government and medical universities need to take measures to correct the number of students in the specialty of “General Practitioner” in order to avoid a growing shortage of primary care physicians in the future until 2030.

Uno de los mayores problemas que enfrenta nuestra sociedad en el siglo XXI es sin duda el desempleo. Este mal síntoma del sector productivo se evidencia no solo en los países en vías de desarrollo sino también en las potencias que hace pocos años eran referentes por su estabilidad económica y altos estándares de calidad de vida. La oferta de empleos es cada vez menor en comparación con la demanda de la población económicamente activa.La tendencia es la reducción de plazas de trabajo tanto en el sector público como en el privado. Ante este hecho, un gran porcentaje de quienes pierden sus trabajos adecuados (jornadas completas, salarios legales, prestaciones), caen en una categoría llamada subempleo que no es otra cosa que oficios temporales, pagados por debajo de los valores fijados por ley y para los cuales por lo general el trabajador esta supercalificado. La mayoría de la población económicamente activa de un país, alguna vez sufrió una para en sus labores o varias, lo que llevó al individuo a esta barra de la estadística laboral.

Aerosols in the atmospheres of cloudy gas giant exoplanets and brown dwarfs scatter and polarize these objects’ thermal emission. If such an object has an oblate shape or nonuniform cloud distribution, the net degree of linear polarization can show an increase ranging from several tenths of a percent to a few percent. Modern high-contrast imaging polarimeters are now poised to detect such low-polarization signals, opening up a new window into the rotational velocities and cloud properties of substellar companions to nearby stars. In this paper, we present the results of a near-IR survey searching for linearly polarized thermal emission from a sample of two planetary-mass companions and five brown dwarf companions using GPI and SPHERE-IRDIS. We probe the subpercent linear polarization regime that typifies polarized free-floating brown dwarfs and place limits on each object’s degree of linear polarization. We relate our upper limits on each target’s degree of linear polarization to its rotation rate, and place our results in the context of rotation rates measured using high-resolution spectroscopy.
Spiral-arm Substructures in the Asymmetrical Dust Rings of the Circumstellar Disk MWC 758
Authors: Shen Bo-Ting , Tang Ya-Wen , Koch Patrick M.
Published: November 2020

Asymmetrical features in disks provide indirect evidence of embedded objects, such as planets. Observed with the Atacama Large Millimeter/submillimeter Array (ALMA), the circumstellar disk in MWC 758 traced with thermal dust continuum emission at wavelengths of 0.9 mm with an angular resolution up to 01 (15 au) exhibits an asymmetrical dust ring with additional features. In order to analyze the structures azimuthally and radially, we split the dust ring into small segments in azimuth. For each segment, we fit two-Gaussian functions to the radial intensity profile. The obtained best-fit parameters as a function of azimuth are analyzed. Three spiral-like arm structures are identified. When fitting the 0.9 mm features with the spiral density wave theory using the WKB approximation, two sets of disk aspect ratios are found: one solution gives relatively low values (∼0.03) while the other solution is at the upper bound of the free parameter (∼0.2). The planet locations suggested by the upper-bound result are similar to the ones determined by Benisty et al. for the NIR polarized intensity image. Comparing the reported spiral-like structures with the higher angular resolution (004) ALMA image in Dong et al., we identify different structures in the west of the disk due to differences in the adopted analysis methods and the respective resolutions of the images.
Accretion and Intercycle Variations in the PMS Interacting Binary AK Sco
Authors: Gómez de Castro Ana I. , Vallejo Juan Carlos , Canet Ada , Loyd Parke , France Kevin
Published: November 2020

There are only a handful of known short-period pre-main-sequence spectroscopic binaries with significant accretion rates (Class II sources). AK Sco stands out in this list because the system is composed of two equal mass F5 stars in a highly eccentric orbit thus both stars get as close as 11 stellar radii at periastron passage. This configuration is optimal for accretion studies because enhanced accretion events can be precisely timed at periastron passage. In this work, we present the results from the monitoring of the AK Sco system with Hubble during three consecutive periastron passages. These data provide a unique data set to spectroscopically characterize accretion and evaluate the intercycle variability of the system. Clear evidence of accretion rate enhancement was observed in cycles 1 and 3: the blueing of the near-UV continuum, the sudden flux increase of important accretion tracers, such as the N V, Si IV, and C IV lines, and also of neutral/singly ionized species such as O I and C II. Also, variations in the Si III]/C III] ratio reveal an enhancement of the electron density by an order of magnitude during the periastron passage. Moreover, in cycle 3, the spectral resolution of the observations obtained with the Cosmic Origins Spectrograph enabled us to discern that the flow was channeled preferentially into one of the two components. The most remarkable feature in the cycle-to-cycle variations was the detection of a notable increase of the UV flux from cycle 1 to cycle 2 that was not accompanied by enhanced accretion signatures.

Megachile sculpturalis(Smith, 1853) (Hymenoptera: Megachilidae) is an invasive solitary bee that is rapidly spreading all over Europe. The present study aims to update the distribution of this species in Italy. The research led to the collection of 177 records, obtained through bibliographic research and data-mining from websites, blogs and social networks. We here present the first record ofM. sculpturalison a Mediterranean island and discuss its possible effect on the native ecosystem. Given the particular discovery ofM. sculpturalison Elba Island (Tuscany), we suggest possible monitoring, containment and possible eradication measures of the species.

Published: November 2020

Thailand has a great diversity of ant fauna as a zoogeographical crossroads and biodiversity hotspot. The last publication presenting a Thai ant checklist was published in 2005. In the present paper, based on an examination of museum specimens and published records, a comprehensive and critical species list of Thai ants is synthesized. Currently, 529 valid species and subspecies in 109 genera among ten subfamilies are known from Thailand with their diversity and distribution within 77 provinces presented and assigned to six geographical regions. Furthermore, Thailand is the type locality for 81 ant species. Forty-one species are here newly recorded for Thailand with photographs illustrating these species. The checklist provides information on distribution and a comprehensive bibliography. This study will also serve as a guide for the upper northeast and central Thailand, which are poorly sampled; a comprehensive reference list relating to endemic taxa and localities where conservation is an important priority, thus an essential resource for policy makers and conservation planners concerned with the management of insect diversity in Thailand; and a list of exotic ant species found in Thailand, which could possibly impact the ecological balance.
L’émergence du standard minimum de traitement des étrangers en droit international
Authors: Dorce Milcar Jeff
Published: November 2020

Durant la fin du xixe et le début du xxe siècles, le standard minimum de traitement des investisseurs étrangers peut se lire dans les œuvres des juristes positivistes comme une norme de civilisation, c’est-à-dire un dispositif civilisationnel qu’il faut coûte-que-coûte imposer dans les relations commerciales internationales. D’origine occidentale et judéo-chrétienne, l’impératif de civilisation qui fonde la définition du standard minimum de traitement postule une protection juridique eurocentrée rejetant les pratiques normatives non occidentales (considérées comme non civilisées). Par ainsi, s’est opérée une nouvelle forme d'intrusion coloniale qui a permis aux États occidentaux de raffermir leur hégémonie sur la scène internationale. Les perspectives tiers-mondistes (l’hostilité latino-américaine d’origine Calvo, en particulier) ont proposé une autre logique de protection des étrangers pour contrecarrer la dynamique occidentale, mais elle ne deviendra pas hégémonique.
De l’idéal démocratique de l’équilibre à la réalité politique du déséquilibre des pouvoirs
Authors: Fokou Éric
Published: November 2020

L’équilibre des pouvoirs n’est qu’un idéaltype. Il recèle dès lors une dimension hypothétique et utopique en ce qu’il ne peut jamais se réaliser pleinement même dans le contexte des démocraties dites évoluées. Cet idéal inaccessible d’équilibre contraste avec la réalité empirique d’un déséquilibre contextuel des pouvoirs en faveur soit de l’exécutif selon que l’on se trouve dans un régime de type présidentiel, soit du législatif, dans un régime de type parlementaire et soit plus généralement du judiciaire dans toute démocratie libérale ou État de droit où l’on observe une régulation, voire un contrôle, soit-il symbolique, en dernier ressort des autres pouvoirs par le pouvoir judiciaire incarné par la juridiction constitutionnelle.

Puissance de l’URSS, misères de l’Allemagne
Authors: Castin-Chaparro Laure
Published: November 2020

Depuis la Seconde Guerre mondiale, la politique allemande de Staline a fait l'objet de perceptions radicalement opposées au sein des cercles dirigeants alliés, puis de controverses et de polémiques nourries dans l'historiographie occidentale. Que voulait en effet l'Union soviétique ? Une Allemagne unie ou divisée, une Allemagne socialiste sur le modèle soviétique ou un régime parlementaire de type occidental dans une Allemagne neutralisée sur le plan militaire ? Une longue consultation des archives de Moscou, puis une confrontation minutieuse avec les documents diplomatiques déjà publiés aux États-Unis, en Grande-Bretagne, en France ou en Allemagne ont permis à l'auteur de saisir, dans cet ouvrage, la genèse et l'évolution de la politique stalinienne, d'analyser le processus de décision en Union soviétique et dans la zone d'occupation en Allemagne, et enfin d'étudier le poids et la marge de manœuvre réels des acteurs politiques et diplomatiques en présence.
Stratégie soviétique et chute du pacte de Varsovie
Authors: Paris Henri
Published: November 2020

Le Pacte de Varsovie représente la plus formidable coalition mili­taire et politique que le monde ait connu depuis deux siècles. En réalité l’organisation du Pacte ne visait qu’à assurer la gestion des Forces alliées et encore plus la direction politique de la coalition, dans la conti­nuité de l’Internationale communiste née au lendemain de la Révolution d’Octobre. Quant au commandement opérationnel des forces alliées, il était assumé par la Direction suprême politico-militaire de l’URSS et par le commandement militaire soviétique.

La stratégie militaire développée par les seuls Soviétiques était d’une redoutable efficacité.

Comble du paradoxe, c’est au stade du plus grand perfectionnement que le pacte de Varsovie s’est effondré en même temps que l’URSS, pour les mêmes raisons, à la suite d’impasses insurmontables dans les domaines militaires, sociaux et économiques. Mais, c’est surtout la chute de l’idéologie communiste qui a entraîné la dislocation de l’ensemble.

Le pacte de Varsovie reste cependant un modèle que les Russes reprennent en le débarrassant de son idéologie pour reconstruire une entité étatique, à partir de la Communauté des États Indépendants, surgie des décombres de la défunte Union soviétique. Le pacte est ainsi la clé de l’avenir.

Cet ouvrage est issu d’une thèse de doctorat soutenue en 1993 à l’Université de Paris-I (Panthéon-Sorbonne) avec la mention « très honorable, avec les félicitations du jury » par le général (CR) Henri Paris. Le directeur de cette thèse était le Professeur René Girault.
Pharmacological aspects of fisetin
Authors: Antika Lucia Dwi , Dewi Rita Marleta
Published: November 2020

Over the past decades, epidemiological studies have concluded that a diet rich in plant-derived products plays a pivotal role in human health. Fisetin (3,3’,4’,7-tetrahydroxyflavone) is a hydrophobic polyphenolic compound primarily found in edible plants (e.g. strawberry, blueberry, apple, grape, persimmon, kiwi, and cucumber). Various preclinical studies have revealed that fisetin exhibits a wide range of pharmacological effects such as antioxidant, anti-inflammatory, anti-carcinogenic, anti-osteoporotic, antimicrobial, and anti-diabetic properties. Therefore, the pharmacological in vitro and in vivo studies on fisetin are discussed in this review. Additionally, this review would be useful for further study regarding the potential of natural products, notably fisetin, and its therapeutic potential for the prevention and treatment of diseases.
Effects of Fear of COVID-19 on Mental Well-Being and Quality of Life among Saudi Adults
Authors: Alyami Mohsen , de Albuquerque Julia Vajda , Krägeloh Christian U. , Alyami Hussain , Henning Marcus A.
Published: November 2020

Background:

The coronavirus disease 2019 (COVID-19) pandemic has been very disruptive, and thus is likely to result in substantial challenges to mental health.

Objectives:

This study aimed to investigate the effects of fear of COVID-19 on the mental well-being and quality of life among Saudi adult population and to evaluate the impact of perceived social support.

Materials and Methods:

This cross-sectional study used an anonymous online survey, where participants were administered the Fear of COVID-19 Scale, Hospital Anxiety and Depression Scale, European Health Interview Survey-Quality of Life and Medical Outcomes Study Social Support Survey. A path analysis was used to investigate the proposed theoretical domain structure linking fear of COVID-19 with perceived social support, mental well-being and quality of life.

Results:

A total of 1029 Saudi adults with a mean age of 33.7 years (SD 11.5) responded to the survey. Descriptive analysis showed that this sample was fearful of COVID-19, anxious and depressed but, at the same time, reported high quality of life and perceived social support scores. Path analysis indicated that increased fear of COVID-19 was directly associated with diminished mental well-being, which in turn was associated with lower quality of life. The beneficial effects of perceived social support were stronger on quality of life than on mental well-being. No direct link was found between fear of COVID-19 and quality of life.

Conclusion:

These findings emphasize the importance of having effective social systems in place to minimize the impact of the COVID-19 pandemic on mental well-being and quality of life.
A Multimodal Human Sensing System for Assisted Living
Authors: Sonia Sonia , Semwal Tushar
Published: November 2020

Introduction: Advancements in sensor technology have resulted in smart systems that can analyze, interpret and understand their surroundings for decision making. Using such intelligent systems for environments such as smart homes, device automation, and hospitals, makes sensing human presence an essential requirement. Human sensing becomes critical, especially in assisted living scenarios such as in elderly care. However, mechanisms for human sensing are not foolproof because of the dynamic nature and ability of human beings to deliberately mislead the sensors.Objective: Objective of paper is to detect human presence in varying environment using non-intrusive sensors.Method: Besides, sensors have inherent limitations, due to either their mechanism of sensing or the environmental conditions, which can cause them to fail in human detection. These limitations can, at times, cause sensors to provide useless data to the system. In this paper, we propose an adaptive multi-modal human sensing mechanism which can autonomously identify and ignore unnecessary data from a set of sensors, thereby reducing computation complexity, reducing false alarm rate and yielding better performance. The effect of sensing when the human being is in motion has also been studied.Results: The results portrayed in the paper prove the efficacy of the proposed multi-modal system over itssingle sensor counterparts when used in changing environments and other proposed multi-modal human sensing.Conclusions: Human sensing is vital to many smart applications such as smart homes, traffic management systems, human-computer interfaces, etc. Since human beings, in general, are always on the move, the use of a dedicated sensor could fail to detect human presence, especially when the ambient parameters around the sensor change. In this paper, a multi-modal human sensing approach has thus been prescribed for overcoming this issue. This work described focused on automating the identification of inappropriate data relayed by some sensors under certain environmental conditions. Experiments reported include both cases - when the sensors are mounted on a static unit (door frame) and also on a mobile robot. The corresponding results reveal that a combination of sensors outperforms the use of individual dedicated sensors for human detection. Analyses of the walking speed of human being have also been studied which endorse the robustness of the approach. However, different directions of motion need exploration in future.
Optimal approximants and orthogonal polynomials in several variables
Authors: Sargent Meredith , Sola Alan A.
Published: November 2020

We discuss the notion of optimal polynomial approximants in multivariable reproducing kernel Hilbert spaces. In particular, we analyze difficulties that arise in the multivariable case which are not present in one variable, for example, a more complicated relationship between optimal approximants and orthogonal polynomials in weighted spaces. Weakly inner functions, whose optimal approximants are all constant, provide extreme cases where nontrivial orthogonal polynomials cannot be recovered from the optimal approximants. Concrete examples are presented to illustrate the general theory and are used to disprove certain natural conjectures regarding zeros of optimal approximants in several variables.

The world's big economies are roiled and going under a devastating threat amid the impact of the COVID-19 pandemic. No country will be safe as this virus will eventually outbreak everywhere, regardless of how countries prepare to avoid it. The economic ramification as well as the stock market crisis will be uncertain due to the extended suspension of economic activities in almost every country. No wonder, the clattered stock markets of Bangladesh which have already got the adjective of “the worst stock market in the world” because of inefficient and irrational fluctuations in previous years will experience a colossal crisis due to the pandemic. The article provides an investigation on comparable analysis of the impact on stock markets of Bangladesh, Dhaka stock exchange, and Chittagong stock exchange, before and after the pandemic situation with current market data. We also examine the potential consequence of policy interventions to the market and the investors during a pandemic.

Authors: BALCI Erdem
Published: November 2020

Bir demiryolu hattının esneme direnci hat performansını önemli ölçüde etkiler. İstenilen esneme direncini hat üzerinde sağlayabilmek için ray pedleri ve travers altı pedlere ihtiyaç duyulur. Ray pedleri, ray ondülasyonlarının engellenmesini ve traverslerin dinamik yük tahribatlarına karşı korunmasını sağlar. Travers altı pedler ise balast tabakasındaki aşınmayı azaltır. Yumuşak ped kullanımı hatta daha eşit bir yük dağılımı sağlarken bir diğer yandan da hat sehimlerini artırır. Bu nedenle, kullanılan pedlerin, maksimum hat performansını sağlayacak şekilde optimum esneme direncine sahip olması gerekir. Bu çalışmada, ray pedleri ve travers altı pedleri kullanımının ray, travers ve balast katmanı üzerindeki etkileri araştırılmıştır. Böylece pedlerin, hat tasarımında göz önünde bulundurulması gereken hususlar üzerindeki etkilerini içeren temel bir kaynak oluşturmak hedeflenmiştir. Çalışma sonucunda elastik pedlerin esneme direncinin, her bir hat katmanı üzerinde gerilme, moment, titreşim ve yer değiştirme kriterleri açısından farklı etkileri olduğu görülmüştür. Yeni inşa edilen veya yenileme çalışması yapılan bir hatta maksimum hat performansının sağlanabilmesi için önerilere yer verilmiştir.

Authors: Wicaksono Adi , Maharani Anita
Published: November 2020

Perceived Usefulness (PU) and Perceived Ease of Use (PEU) are factors that can affecting Behavioural Intention (BI) in the Technology Acceptance Model (TAM). This study aims to determine the effect of PU and PEU on BI of PT XYZ users. This research is a non-experimental study using quantitative methods and a random sampling technique. Data were collected through a questionnaire and processed using Statistical Product and Service Solution (SPSS) with a version of 22.00. There were 80 participants in the research, divided into 58 participants who were PT XYZ users and 22 other participants who had never used PT XYZ. The results showed that there was a significant effect of PU and PEU on BI with a value of F = 95.483, R2 = 0.713, and p = 0.000 < 0.05. The contribution of PU and PEU to PEU was 71.3%. Then, partially PU contributed 62.4% and PEU contributed 68.9% to BI. Thus, it can be concluded that for PT XYZ users, the effect of PEU is greater than PU.
