Personality Traits Affecting Risky Riding Behavior: An Application of an Extended Theory of Planned Behavior
Authors: Le Luu Van , Nguyen Long Xuan , Chu Minh Cong , Huynh Nathan
Published: December 2023

The primary objective of this study is to investigate the influence of personality traits such as anxiety, sensation seeking, altruism, anger, and normlessness on young powered two-wheeler riders’ risky riding behavior. The theory of planned behavior (TPB) is extended to include personality traits forming an extended TPB (ETPB). The ETPB model is used to examine how personality traits directly influence risky riding behavior and indirectly influence risky riding behavior through latent mediating factors. The secondary objective is to examine the differences in interactions between personality traits, mediating factors, and risky riding behaviors of those who have been and have not been involved in traffic accidents. The study sample included 535 high school students in Phu Yen, Vietnam. The results showed that personality traits, directly and indirectly, influence risky riding behaviors through the mediating construct. Young riders with sensation-seeking, anger, and normlessness have a higher frequency of risky riding behavior than those with anxiety and altruistic personality traits. Sensation seeking, anger, and normlessness indirectly influence risky riding behavior through risk perception and subjective norms. In addition, the results also show a clear difference in the relationship between the personality and behavior of people who have been involved in traffic accidents and those who have never been involved in accidents.

The objective of this research was to determine the relationship between the cost of post-investment in roads and economic development in the La Libertad region from 2015 to 2022. It was basic research with a quantitative approach, non-experimental design, and correlational scope. A documentary analysis was carried out by applying a record card, whose information collected was analyzed with descriptive, multiple correspondence and correlational techniques, finding that from 2015 to 2022, the post-investment costs reach PEN 85,562,363.47, resulting in the benefit of 1310.10 km. Likewise, it was found that economic development, through the indicator of monetary poverty, ranged between 20.83% and 31.90%, and that household access to the four basic services reached 77.9% in 2021 and 78.7% in 2022. It is concluded that in the La Libertad region, the costs of post-investment in roads are significantly related to economic development through the monetary poverty dimension in its two indicators: total and extreme poverty (r: −0.788, p-value: 0.02; r: −0.729, p-value: 0.04, respectively). The other dimensions did not show a relationship; however, these findings do not contradict the theoretical contributions and studies that do determine this.

Authors: Choi Wonjae , Kim Seonggyu
Published: December 2023

This study discusses the development of a software-centered EdTech (Education Technology) class model via the implementation of a course titled “3D Time Machine” at a 4-year university in the Republic of Korea over two semesters. The course focused on teaching the 3D modeling software Blender within the history department. The primary objective of offering this course was to equip students from the digital generation with the capability to manipulate digital technology effectively for their sustainable lives and individual development. By studying historical materials and accumulating domain knowledge, students could construct their narratives from their unique perspectives. This aimed to foster their proficiency in digital technology operation, preparing them for a sustainable education environment increasingly centered around virtual worlds. As the use of virtual worlds gains prominence in educational settings, there is a growing need to incorporate curricula that prepare students to thrive in a “leaving no one behind” society as well-prepared citizens. Assessing the digital competencies of contemporary university students and designing instructional models with particular attention to their needs is becoming increasingly important. This research draws insights from interviews, conducted in both face-to-face and written formats, with students who participated in the “3D Time Machine” course. The interviews revealed valuable insights that can be actively incorporated into the development of software-centered EdTech instructional models. They reported that they expanded their perceptions as they learned how to make their ideas tangible. The course helped students overcome their fear caused by the vagueness of digital technology. These opinions significantly contribute to the development of practical digital educational courses that can be easily and rapidly acquired and applied within virtual educational environments. In conclusion, this kind of course effectively employs 3D modeling technology, a software-centered EdTech, as a core element in helping students develop their narratives rapidly and diversely, thereby playing a crucial role in their ability to articulate their unique perspectives.

Currently, there is an environmental problem associated with cleaning the seas and oceans from a large number of dead jellyfish thrown ashore and into the coastal zone, which is urgent and requires solutions. This research aims to study the formation and properties of cement and concrete with added jellyfish mass and to understand the effects of this addition. Tests were carried out on formulations containing dead jellyfish mass in amounts from 0.2% to 1.6%. This study focused on the density, shear stress, workability, water separation, strength, and water absorption of cement and concrete, which are the main properties that characterize cement and concrete in construction. Adding 0.6% dead jellyfish to this composition resulted in greater effectiveness compared to the control composition. With this dosage, the normal density of the cement paste decreased by 16.3%, there was a 32% decrease in ultimate shear stress, the workability expressed in the cone slump increased by 60.8%, the water separation of cement decreased by 19.7%, the increase in compressive strength was 10.6%, and water absorption decreased by 15.5%. An analysis of the structure showed that the modification of concrete with dead jellyfish mass reduces the defectiveness of a concrete structure compared to the composition of the control structure.

Corrosion inhibitors are widely used as an important tool for the prevention and remediation of different materials exposed to corrosive industrial processes. Corrosion inhibitors are usually added to acid pickling solutions to reduce the deterioration of metallic materials and particularly, corrosion due to hydrochloric acid. In this work, three bis-Schiff bases (BS2, BS4 and BS8) were synthesized and characterized using spectroscopic methods, and their anti-corrosive effects on AISI 1020 carbon steel in a hydrochloric acid solution were studied using gravimetric and electrochemical techniques and quantum chemical methods. The results showed that all substances act as potential corrosion inhibitors as BS8 exhibited the highest efficiency (98%) of all methods. The compounds adsorbed on the metal surface were as per the El-Awady adsorption isotherm. Morphological aspects of the metal were observed upon applying SEM, and the theoretical results acquired from the quantum chemical calculation for molecular properties and the Fe(110) surface adsorption proved to be compatible with the experimental results.

Published: December 2023

In machine learning, classifiers have the feature of constant symmetry when performing the attribute transformation. In the research field of tourism recommendation, tourists’ interests should be mined and extracted by the symmetrical transformation in founding the training dataset and creating the classifier, so as to ensure that the recommendation results meet the individualized interests and needs. In this paper, by applying the feature of constant symmetry in the classifier and analyzing the research background and existing problems of POI tour routes, we propose and construct a tour route recommendation model using improved symmetry-based Naive Bayes mining and spatial decision forest search. First, the POI natural attribute classification model is constructed based on text mining to classify the natural attributes of the destination POIs. Second, the destination POI recommendation model based on the improved symmetry-based Naive Bayes mining and decision forest algorithm is constructed, outputting POIs that match tourists’ interests. On this basis, the POI tour route recommendation model based on a spatial decision tree algorithm is established, which outputs the optimal tour route with the lowest sub-interval cost and route interval cost. Finally, the validation and comparative experiments are designed to output the optimal POIs and tour routes by using the proposed algorithms, and then the proposed algorithm is compared with the commonly used route planning methods, GDM and 360M. Experimental results show that the proposed algorithm can reduce travel costs by 4.56% and 10.36%, respectively, on the optimal tour route compared to the GDM and 360M and by 2.94% and 8.01%, respectively, on the suboptimal tour route compared to the GDM and 360M, which verifies the advantages of the proposed algorithm over the traditional route planning methods.

The coronavirus COVID-19 pandemic initially witnessed in China (Wuhan) brought unprecedented devastation in China and other countries. No country was immune to the virus, and heads of state and policymakers had to draw up and implement robust domestic policies to contain the spread of the virus. From an Afrocentric perspective, the virus had dire consequences for African states, considering that most are minor and driven by weak economies. Narrowing this down to South Africa, the virus brought significant repercussions. In South Africa's 29 years of democracy, the state still faces major social ills such as unemployment, poverty, and inequality. The virus’s arrival worsened matters for the South African government, which needed new measures for the majority black marginalised population. As the government could not do it alone, the role of third parties, such as civil society, became fundamental as civil society is of the utmost importance globally, particularly for Africa and Developing Economies. Driven by a qualitative research approach, the purpose of this article was to ponder the role of civil society in developing economies with specific reference to South Africa during the COVID-19 pandemic. The findings show that the government’s role as a single actor in dealing with the pandemic was deficient, as the pandemic crippled the health system. Civil society was pivotal in South Africa during the pandemic and assisted the government with various socio-economic activities, particularly for the marginalised population.

Czy stare i nowe miasto były skazane na konflikt? Głos w dyskusji w świetle nowszych badań
Authors: Słoń Marek

Were the old and new towns doomed to conflict? A voice in the discussion in the light of newer research

The article consists of two parts. In the first one I present the causes and forms of conflict between municipalities in one urban centre in medieval Poland. It is a summary of and supplement to the material presented in my book about double and multiple cities in medieval Europe, limited here to Polish lands. In the second part, I engage in a debate with works published since then that question the existence of competition and conflict between municipalities: by Marcin Starzyński in relation to Kazimierz in Cracow and by Piotr Samól in the case of Jungstadt in Gdańsk.
Direct proximity determined the intensity of contacts and mutual dependence, which led to tensions, and in some circumstances could lead to acts of violence and material destruction of weaker municipalities. The biggest area of tension was economic rights. Among them, the right to cut cloth, sell beer, rights to markets and fairs played a special role. The main centre usually aimed for a monopoly and sought to encompass the city’s broadly defined environs. However, the essence of the dispute was not the economic or craft activity, but its removal from the control of the old town authorities and the functioning of an independent municipality. The older and usually stronger commune looked down on its neighbour, while the younger one felt humiliated and wronged. In addition, direct proximity often caused military problems: weaker fortifications of the new town or their absence became a cause or pretext for restricting or partially or even completely eliminating construction. Open violence against a neighbouring centre was contrary to the interests of the superior of these municipalities, so it happened rarely, usually during a war in the area. At the same time, tension and rivalry between municipalities did not exclude cooperation in many areas or pragmatic benefits from mutual proximity. It probably constituted a potentially significant factor stimulating the development of such complex urban structures.
Król, wójt, mieszczanie. Rywalizacja o władzę w małopolskich miastach królewskich w dobie jagiellońskiej
Authors: Mikuła Maciej

The king, the vogt, the burghers. Fight for power in the royal towns of Małopolska in the Jagiellonian era

The hereditary vogtei was a natural consequence of foundation under German law. In most cases it was assumed by the locator and was associated with powers of a lord, including judicial powers. A hereditary vogt was essentially to be the representative of the town’s owner — thus, in the case of royal towns, the monarch (the vogt as a brachium regale). However, already by the end of Casimir the Great’s reign we can observe a move away from the idea of hereditary vogtei. Probably one of the reasons for this was the reduction in the effectiveness of the hereditary vogt’s actions due to the division of the vogtei through inheritance. However, during the reign of Władysław Jagiełło the hereditary vogtei was used for personal politics — as another type of property which could be used to reward someone’s services. There is a noticeable trend of accumulating property in the hands of noble families. Thus, an authority that undermined urban autonomy was being consolidated in the landscape of the urban system. The term denotes the extent of the burghers’ independence from outside entities in the management of the town, including with regard to the election of councillors. The following correlations have been noted between the extent of autonomy and the nature of hereditary vogtei: rich vogtei in the hands of a nobleman effectively limited the autonomy of a town included in the so-called II or III tax category (Biecz, Bochnia, Myślenice and Pilzno); poor vogtei, even one held by a starosta/ tenutary, was an insufficient basis for effectively limiting urban autonomy (Będzin, Ciężkowice, Częstochowa); the absence of vogtei (Proszowice) or vogtei bought out by the town (Połaniec, Sandomierz, Wieliczka) are circumstances that generally strengthen urban autonomy; the lack of vogtei (Chęciny) or vogtei bought out by a town (Nowy Sącz) may not have translated into significant autonomy, if the castle starosta successfully opposed it and the economic potential of the vogtei was small.
Ekspor Nikel Indonesia Pasca Gugatan Oleh Uni Eropa Ditinjau Dari Teori Potensi Keunggulan Komparatif
Authors: Suryadarma Fatika Redita , Faqih Maldini
Published: December 2023

Indonesia telah menjadi salah satu produsen nikel terbesar di dunia. Namun, baru-baru ini Uni Eropa telah menggugat Indonesia ke Organisasi Perdagangan Dunia (WTO) atas tindakan diskriminatif dalam ekspor nikel. Hal ini menimbulkan kekhawatiran akan dampaknya terhadap industri nikel Indonesia. Penelitian ini bertujuan untuk memberikan pemahaman yang lebih baik tentang potensi kemajuan ekspor nikel Indonesia dan mengembangkan strategi kebijakan yang tepat untuk menghadapi tantangan yang dihadapi pasca gugatan oleh Uni Eropa, dengan mempertimbangkan teori potensi keunggulan komparatif. Metode yang digunakan dalam penelitian ini adalah metode penelitian kualitatif. Hasil penelitian menunjukkan bahwa meskipun Indonesia menghadapi gugatan oleh Uni Eropa terkait kebijakan ekspor nikel, Indonesia masih memiliki keunggulan komparatif dalam produksi nikel. Faktor yang mempengaruhi keunggulan komparatif Indonesia dalam produksi nikel adalah ketersediaan sumber daya alam dan lokasi strategis. Untuk memperluas pangsa pasar ekspor nikelnya di luar Uni Eropa, Indonesia dapat mengambil beberapa strategi, seperti menjalin kemitraan dengan negara-negara di luar Uni Eropa dan meningkatkan nilai tambah produk nikel dengan memproses nikel menjadi produk jadi. Melalui strategi-strategi tersebut, Indonesia dapat memperluas pasar ekspornya dan mengurangi ketergantungannya pada pasar Uni Eropa.
The Father’s Responsibility for the Fulfillment of Child Support Post-Divorce
Authors: Lira M. Adnan
Published: December 2023

This study aims to understand responsibility and identify factors influencing a father’s inability to provide child support post-divorce. This study uses a normative legal research method. The collected legal material is then qualitatively analyzed to describe the problem and answer the study objectives. The results show that the primary responsibility for child support and education costs post-divorce lies with the father. The father’s failure to fulfill this responsibility results in serious consequences, both legally and socially. Factors influencing a father’s inability or failure include deteriorating economic conditions post-divorce, limited communication between father and child, and situations where the mother is financially more stable and takes over the role of providing child support. Therefore, it is recommended that relevant stakeholders develop policies and programs that support fathers post-divorce in meeting their responsibilities for child support and children’s educational expenses. It is vital to provide fathers access to economic resources, training, and legal assistance to help them overcome financial difficulties post-divorce. Additionally, there should be facilitation of more effective communication between father and child, involving counseling or family mediation. In situations where the mother has better financial stability, stakeholders should consider a balance in the division of child support responsibilities, enabling both parents to contribute according to their capabilities. This approach will help minimize negative impacts on the child and acknowledge the changing socio-economic dynamics post-divorce.
THE IMPACT OF CONSUMER FATIGUE FROM MAKING DECISION ON THE FORMATION OF BRAND LOYALTY
Authors: Kovshova Iryna , Savchenko Kira
Published: December 2023

Purpose. The purpose of the article is the formation of theoretical, methodological and practical foundations for the implementation of marketing tools to assess the impact of consumer fatigue from making everyday decisions on brand loyalty and purchasing behaviour in stores.

Methodology of research. The theoretical and methodological basis of the article was formed by the provisions of behavioural economics, neuro-marketing, and branding. The study is based on the dialectical method of learning the influence of consumer fatigue from decision-making on brand loyalty.

General scientific and special methods are used within the limits of the mentioned approach, in particular: comparison – to determine the advantages and disadvantages of different groups of marketing tools; questionnaire survey – for a pilot study of the criteria for making a decision on the purchase of goods by consumers in stores; mathematical modelling – for evaluating the data obtained during the experiment and determining the tendencies of choosing the company's product or brand by consumers during fatigue; analysis and synthesis – to form a mechanism for the implementation of neuro-marketing tools by companies; induction and deduction – to interpret conclusions based on research results.

Findings. The phenomenon of consumer decision fatigue resulting from repeated choice-making is explored, leading to mental exhaustion and impaired behaviour control, affecting brand loyalty. A concept is formulated for the application of neuro-marketing tools to understand consumer behaviour in retail stores, which engages all human sensory organs, including audio influence, visualization, tactile stimulation, scent influence, and taste stimulation.

Pilot study of the purchasing behaviour of consumers in a state of physical or mental fatigue and without it was conducted. It has been established that closer to the evening, consumer fatigue from decision-making is observed, as during the day people may be under the influence of stressful factors, depleting emotional and cognitive resources. The factors that are important in making a decision regarding the choice of a product of a certain brand are singled out. The hypothesis regarding the influence of consumer fatigue from decision-making on the formation of brand loyalty was confirmed.

Originality. The concept is formulated of using neuromarketing tools for a better understanding of consumer behavior in stores, a more detailed analysis of the decision-making process and their purchasing behavior, the formation of habits and loyalty to company brands, consumer reactions to product packaging and labeling in a state of fatigue.

Practical value. The results of the pilot study will help create more effective marketing campaigns using a personalized approach to consumers and simplified communication.

Key words: consumer behaviour, decision fatigue, marketing, shopping in stores, brand loyalty, neuro-marketing.

Impact of the type of breast cancer on the biodiversity of the vaginal Candida represented by estrogen receptor and its levels
Authors: AL-Janabi Ali Abdul Hussein S. , Mohammed Jawad Ruaa Kadhim , Hassan Abdul Razzak Kalaf
Published: December 2023

Aim: Estrogen has an important role in the colonization of Candida through the presence of estrogen receptors (ERs). These ERs are usually used to categorize breast cancer into two types, positive and negative ER breast cancers. The effect of variation in the type of ER and estrogen levels on the biodiversity of Candida in the vagina was investigated. Methods: A case-control study, consisting of three groups of 30 patients with ER-positive, 29 with ER-negative breast cancer, and 30 healthy individuals, was carried out. The diversity and counting of Candida spp. in the vagina and estrogen levels were identified in all subjects. Results: The growth of Candida spp. was high in the vagina of patients with ER-positive breast cancer when estrogen was at normal levels. Otherwise, its growth was enhanced by high levels of estrogen in patients with ER-negative breast cancer. Conclusions: Estrogen levels have no effect on the vaginal content of Candida spp. in patients with ER-positive breast cancer, unlike those with ER-negative breast cancer. The principal recommendation from this study is that vaginal candidiasis and estrogen levels should be checked in patients with ER-negative breast cancer.

Authors: Laopajon Witida , Takheaw Nuchjira , Kotemul Kamonporn , Pata Supansa , Hongeng Suradej , Kasinrerk Watchara
Published: December 2023

Aim: The present study aims to generate chimeric mouse single-chain variable fragment (scFv) and immunoglobulin G1 (IgG1) crystallizable fragment (Fc) antibody against disialoganglioside (GD2) for the treatment of neuroblastoma (NB). The generated scFv-IgG Fc antibody, lacking first constant domain of heavy chain (CH1), is of a smaller size than the natural antibody and has anti-tumor activity.
Methods: Vector for scFv-IgG Fc antibody was constructed and scFv-IgG Fc antibody was expressed in human embryonic kidney 293T (HEK293T) cell line. Purification of scFv-IgG Fc antibody from the culture supernatant of transfected HEK293T cells was performed by Protein G affinity chromatography. The structure and binding activity of scFv-IgG Fc antibody were verified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), western blotting (WB), and immunofluorescence techniques. Anti-tumor activities by antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP) were determined.
Results: Using plasmid fusion-human IgG1-Fc2 tag vector (pFUSE-hIgG1-Fc2), a plasmid vector encoding chimeric mouse scFv and hIgG1 Fc antibody against GD2 was successfully constructed. This vector was transfected into human HEK293T cells to produce scFv-IgG Fc antibody. The transfected HEK293T cells could produce chimeric scFv-IgG Fc antibody against GD2, which lacks the IgG heavy chain CH1 domain but carries CH2 and CH3 domains. The chimeric antibodies could be purified from the culture supernatant of the transfected HEK293T culture in the presence of zeocin drug. The produced GD2 scFv-IgG Fc antibodies, which are smaller in size than the intact antibody, could trigger the killing of GD2 expressed NB cell line SH-SY5Y by ADCC and ADCP mechanisms.
Conclusions: The results indicate that chimeric scFv-hIgG Fc antibody, lacking heavy chain CH1 domain, could mediate antibody induced anti-tumor activities. The small size of this type of chimeric antibody may be employed as anti-GD2 antibody for NB therapy.
Contemporary aspects of quality management in audit services
Authors: MOSKAL Nataliia , BANDURA Zvenyslava , KRIL Yaroslava
Published: December 2023

Introduction. New International Standard on Quality Management have brought significant changes to the approach to quality management in auditing activities. According to ISQM 1, auditing entities were required to develop and implement quality management systems before the standards came into effect and conduct an assessment of the effectiveness of these systems within one year of implementation.
The purpose of the paper is to contribute to the development of scientific understanding and practical application of quality management in the auditing sphere to ensure the quality, reliability, and trustworthiness of auditing services.
Results. According to ISQM 1, a quality management system must operate continuously and respond to changes in the circumstances of the entity and its objectives. This system has a comprehensive nature and encompasses eight key components, including the assessment of entity risks, leadership and management, adherence to ethical requirements, establishment and maintenance of client relationships and engagements, performance of engagements, resource utilization, information exchange and communication, and monitoring and remediation. The primary innovation is the risk-based approach to building a quality management system, which is based on risk assessment and includes setting quality objectives, identifying and evaluating quality risks, and developing actions to mitigate them. Quality objectives are determined by the auditing entity and must include objectives related to managing the entity, adhering to ethical requirements and independence, client and engagement acceptance and performance, and resource objectives, including human resources. Measures taken by the entity in response to quality risks may relate to the entity's activities as a whole or be specific to individual engagements. The nature, extent, and timing of these measures should be based on the results of the identified risks assessment.
Conclusion. Therefore, the implementation of new quality management standards in auditing aims to enhance the quality of auditing services and ensure the reliability of financial information.

This research aims to test the influence of human capital empirically, the use of information technology, and internal control on the quality of financial reports. The sample used in this research was saturated, namely 30 BPRs with addresses in Denpasar. This research data is quantitative and was collected using a questionnaire. The analysis technique used is the multiple linear regression analysis technique. The results of this research are that human capital has a positive and significant effect on the quality of financial reports, the use of information technology has a positive and significant effect on the quality of financial reports, and internal control has a positive and significant effect on the quality of financial reports. In addition, this provides implications for future researchers to add other variables such as internal audit, accounting information systems, and others. It is necessary to increase the number of samples and expand the scope of research, which is more comprehensive than BPR in Denpasar.

The research examines the influence of return on assets, debt-to-equity ratio, current ratio, and price-earnings ratio on share prices in banking sector companies listed on the Indonesia Stock Exchange for 2019-2021. This research obtained 36 companies as samples using a purposive sampling technique with three years of observation. he total population of companies is 47, and the sample obtained was 36 companies that met the criteria using the purposive sampling method. The type of data applied is a quantitative approach. The data collected was then analyzed using multiple linear regression. The testing method uses multiple linear regression analysis techniques, classical assumption tests, F-tests, and T-tests. Judging from the results of the partial analysis, it is clear that there is a positive and significant influence of the return on assets and price-earnings ratio variables on stock prices. On the other hand, the debt-to-equity ratio variable and the current ratio variable have a negative and insignificant effect on stock prices.

We present the first analysis of JWST near-infrared spectroscopy of stellar flares from TRAPPIST-1 during transits of rocky exoplanets. Four flares were observed from 0.6–2.8 μm with the Near Infrared Imager and Slitless Spectrograph and 0.6–3.5 μm with the Near Infrared Spectrograph during transits of TRAPPIST-1b, f, and g. We discover Pα and Brβ line emission and characterize flare continuum at wavelengths from 1–3.5 μm for the first time. Observed lines include Hα, Pα–Pϵ, Brβ, He i
λ0.7062 μm, two Ca ii infrared triplet (IRT) lines, and the He i IRT. We observe a reversed Paschen decrement from Pα–Pγ alongside changes in the light-curve shapes of these lines. The continuum of all four flares is well described by blackbody emission with an effective temperature below 5300 K, lower than the temperatures typically observed at optical wavelengths. The 0.6–1 μm spectra were convolved with the Transiting Exoplanet Survey Satellite (TESS) response, enabling us to measure the flare rate of TRAPPIST-1 in the TESS bandpass. We find flares of 1030 erg, large enough to impact transit spectra occur at a rate of

flare day−1, ∼10× higher than previous predictions from K2. We measure the amount of flare contamination at 2 μm for the TRAPPIST-1b and f transits to be 500 ± 450 and 2100 ± 400 ppm, respectively. We find up to 80% of flare contamination can be removed, with mitigation most effective from 1.0–2.4 μm. These results suggest transits affected by flares may still be useful for atmospheric characterization efforts.

We derive the bolometric luminosities (L
bol) of 865 field-age and 189 young ultracool dwarfs (spectral types M6–T9, including 40 new discoveries presented here) by directly integrating flux-calibrated optical to mid-infrared (MIR) spectral energy distributions (SEDs). The SEDs consist of low-resolution (R ∼ 150) near-infrared (NIR; 0.8–2.5μm) spectra (including new spectra for 97 objects), optical photometry from the Pan-STARRS1 survey, and MIR photometry from the CatWISE2020 survey and Spitzer/IRAC. Our L
bol calculations benefit from recent advances in parallaxes from Gaia, Spitzer, and UKIRT, as well as new parallaxes for 19 objects from CFHT and Pan-STARRS1 presented here. Coupling our L
bol measurements with a new uniform age analysis for all objects, we estimate substellar masses, radii, surface gravities, and effective temperatures (T
eff) using evolutionary models. We construct empirical relationships for L
bol and T
eff as functions of spectral type and absolute magnitude, determine bolometric corrections in optical and infrared bandpasses, and study the correlation between evolutionary model-derived surface gravities and NIR gravity classes. Our sample enables a detailed characterization of BT-Settl and ATMO 2020 atmospheric model systematics as a function of spectral type and position in the NIR color–magnitude diagram. We find the greatest discrepancies between atmospheric and evolutionary model-derived T
eff (up to 800 K) and radii (up to 2.0 R
Jup) at the M/L spectral type transition boundary. With 1054 objects, this work constitutes the largest sample to date of ultracool dwarfs with determinations of their fundamental parameters.
