Purpose: To analyze the influence of environmental awareness on university social responsibility among students of a private university in Chimbote, Peru.

Theoretical framework: Theories associated with environmental awareness, university social responsibility and other factors were addressed.

Method: A mixed Dexplis-type approach was applied, with a non-experimental and cross-sectional design, where the total population was 1180 university students and the probability sample for the survey was 290 students and the non-probability sample for the interview was 30 students that served to collect quantitative and qualitative data respectively. Quantitative data were obtained through the ECA-FMEP instrument of environmental awareness (Laso et al., 2019), whose reliability was assessed by Cronbach's Alpha coefficient α = 0.905 and the RSU was evaluated through the RSU scale instrument of university social responsibility (Serrano et al., 2022), whose reliability was assessed by Cronbach's Alpha coefficient α = 0.868 which was obtained by being applied to a pilot test of 30 learners, where the quantitative data obtained were then processed in SPSS, and the qualitative data were obtained from the answers to the questionnaire of open questions that were evaluated with Atlas.ti software considering 20 codes, 12 sub categories and 8 categories, also taking into account other factors that influence the USR.

Results and conclusions: The results support a very high degree of positive correlation between environmental awareness and university social responsibility with an rs = 0.967 and a significance level of p = 0.000, where the coefficient of determination shows that environmental awareness influences 94.7% of university social responsibility, while the remaining 5.3% is affected by other factors. It is concluded that there is a very high positive correlation and there is a 94.7% influence of environmental awareness on university social responsibility, where the remaining 5.3% is due to other factors such as socioeconomic level, previous education, personal experiences, influences and the legal framework in force.

Originality/value: To provide insight into students' perceptions on the management of environmental awareness and its influence on university social responsibility.

Published: March 2024

Objetivos: Analisar, laboratorialmente, escaneamentos de superfícies de perfis de emergência peri-implantares, a partir da utilização de diferentes postes de escaneamento. Materiais e Método: A partir da utilização de três modelos MAV, foram executadas perfurações com o auxílio de guias cirúrgicas e análogos dos implantes Unitite Prime (SIN), Helix GM Narrow (Neodent) e TRI Bioneck (Dérig) foram instalados, respectivamente, nos modelos M1, M2 e M3, sendo um análogo por modelo. Cada modelo foi escaneado com um poste de escaneamento específico, resultando em arquivos STL, cujas imagens foram utilizadas para a análise visual dos perfis de emergência escaneados. Resultados e Discussão: A análise visual das imagens advindas dos arquivos STL, mostrou que o EPS (EPS - Emergence Profile Scanbody - Pat. Req. BR1020200019481), o GM Implant Intraoral Scanbody (Neodent, Brasil) e o transfer para escaneamento TRI NP (Dérig, Brasil) permitiram o correto escaneamento dos respectivos perfis de emergência. Conclusões: Os três postes de escaneamento utilizados podem obter bons resultados clínicos quando da necessidade de transferência do posicionamento 3D do implante endósseo associado à cópia do perfil de emergência peri-implantar. A análise geométrica a ser realizada na fase II deste estudo será fundamental para verificar a superioridade de um ou outro poste de escaneamento, na captura do perfil de emergência peri-implantar. São indicadas análises adicionais para perfis de emergência de outros elementos dentários, uso de outros postes de escaneamento, assim como da performance de outros escâneres intraorais.

Initial Pole Axis and Spin Direction Estimation of Asteroids Using Infrared Imagery
Authors: Kuppa Koundinya , McMahon Jay W. , Dietrich Ann B. 
Published: March 2024

Knowing the pole axis of an asteroid is vital to autonomous asteroid exploration efforts. Ground-based initial pole estimation methods are time and data intensive and produce estimates with large uncertainties. These errors have a significant impact on proximity navigation, shape modeling, and scientific data for small body missions. In this paper, a new method of obtaining this information from onboard spacecraft imagery is presented. The proposed method estimates the pole from onboard infrared imagery using the camera-asteroid geometry. This method does not require a prior and is designed to work in a vast majority approach trajectories due to the use of infrared images. The method is applied to simulated infrared images of asteroids 101955 Bennu and 25143 Itokawa as well as real infrared images of asteroid 162173 Ryugu from the Hayabusa2 mission. The average pole errors using this method on Bennu and Itokawa images are approximately 2 and 6 deg, respectively. The pole estimate error on the Ryugu images is approximately 8 deg. The algorithm is shown to be sensitive to the percentage of spin period imaged and the spacing between the images.

Published: March 2024

Статья посвящена сравнительно-сопоставительному анализу языковых средств выражения метафорического представления категории времени в русском и тувинском языках. Цель исследования — установление особенностей метафорической репрезентации категории времени средствами флективного русского языка и агглютинативного тувинского языка. Предмет исследования — метафорические словосочетания со словами «время», «үе» ‘время’, «шаг» и «шак» ‘час’. Материалом для исследования служили лексикографические источники. Использованы методы лексикографического и компонентного анализа.
Рассмотрены две модели времени — модель, связанная непосредственно с самим временем (модель Потока времени) и модель, ориентированная на человека (модель Пути человека). Отмечены особенности членения того или иного смысла выражений со словами «время», «үе» ‘время’, «шаг» и «шак» ‘час’ на значения в типологически разных языках. Выявлено, как единое мыслительное содержание передаётся различными языковыми средствами в событийном флективном русском языке и статичном агглютинативном тувинском языке.
Сходства выражения категории времени основаны на присутствии в обоих языковых картинах мира универсальных метафорических моделей: время — движение, необратимое движение, движение с разной скоростью, время, движущееся со средней скоростью. Различия связаны с лексическим выражением категории времени: в русском языке — с помощью глаголов либо фразеологизмов, в тувинском — с помощью словосочетаний, содержащих существительные, прилагательные, глаголы и наречия.

Published: March 2024

Objectives
To determine the possible aetiopathogenesis of co-occurrence of granulomas with different malignancies in different body sites.

Material and methods
All cases with granuloma formation observed in draining lymph nodes or in the primary site of malignant tumors were included in the present study. After routine histopathology examination, modified Ziehl-Neelsen (ZN) staining for Mycobacteria was carried out in all the cases. Detailed history, especially of Tuberculosis, sarcoidosis, neoadjuvant chemotherapy, radiation, or previous procedure, was recorded.

Results
11 out of 35 cases (31.4%) had granulomas within the primary tumor, while 24 cases out of 35 (68.6%) showed nodal granulomas. Of the 24 cases, 5 cases had nodal metastatic tumor deposits. Also, necrotizing granulomas with AFB were significantly more as compared to AFB in non-necrotizing granulomas (p value of 0.05). Of the total cases, 20% had an attributed risk factor. Three cases received neoadjuvant chemotherapy, and three had a history of systemic tuberculosis, while one case had associated Crohn’s disease.

Conclusion
We recommend to characterize granulomas as necrotizing/nonnecrotizing, confluent/discrete, tumor deposit present/absent; prior history of systemic/local illnesses (like SS, TB, fungal infections, IBD, etc.); prior history of CT/RT; and to follow routine ZN staining in all cases of granulomas with malignancy.

Minor rotor tines and knives soil interaction. Total power calculation for minor rotor drive
Authors: Nikolaiev V. A. 
Published: March 2024

Introduction. The problem of fast and high-quality road construction, when economic facilities and settlements are spatially separated, located at a considerable distance from each other, cannot be solved without the use of a complex of continuous units. An important element of the continuous unit forming the ditch and the unit for tunneling is the direct-flow rotary ripper. Current theoretical studies are not sufficient to calculate the interaction with the soil of the elements of a direct-flow rotary ripper. The lack of theoretical justification for the parameters of direct-flow rotary rippers hinders their use. Therefore, there is a need for theoretical research to identify the geometric, kinematic, dynamic and energy parameters of structural elements.The method of research. Methods for calculating the required power to drive the teeth, to separate the seam from the soil mass with knives and divide it into fragments, to overcome the inertia force of the incoming soil on two small rotor knives, to accelerate the soil towards the large rotor, to move the soil towards the large rotor, to overcome the friction force of the soil on the front surface of the knives have been developed. The total power required to drive the small rotor corresponds to the sum of the powers: for the introduction of a cone with a spiral knife into the ground, for the drive of the teeth and for the drive of the knives.Results. On the basis of the developed methods, the parameters were calculated. From the flat and spatial model of the forces of interaction with the ground of the elements of the small rotor, their resultant, their components, and normal forces are revealed. The friction force of the soil on the front surface of the knife is calculated. The total power for the drive of the small rotor and the volumetric energy for the introduction of the small rotor into the ground are calculated.Conclusion. The energy costs for driving small rotor knives include: energy for separating the reservoir and dividing it into fragments, energy for overcoming the pressure of the soil on the front surface of the knife, energy for accelerating the soil, energy for moving the soil, energy for overcoming the friction force of the soil on the front surfaces of the knives. The total energy cost of the small rotor drive includes the energy required to introduce the spiral knife cone, teeth and knives of the small rotor into the ground. As a result of the calculations, the power to drive the teeth of the small rotor is 735 W, the total power required to drive the small rotor is 2.2 kW. The volumetric energy for the introduction of a small rotor into the ground is 33.1 kJ / cubic meter.

Sustainable road construction is instrumental in improving connectivity among regions and economies while also offering road users a diverse range of options within the traffic network. To ensure optimal road performance for users, it becomes essential to allocate adequate maintenance funds that correlate with the planned service life. This necessity originates from a profound understanding of the significant influence maintenance funds have on road steadiness. Therefore, this study aims to establish a comprehensive road steadiness model, investigating the influence of toll roads as new routes and the impact on maintenance funds. The analysis included national roads across 15 cities in Central Java Province, Indonesia, covering a distance of 759.75 km from 2018–2023. Using a quantitative approach, the study adopted the Curva Expert program to evaluate the values of road steadiness and maintenance funds. The results showed a 5.78% enhancement in road steadiness over the period from 2018 to 2023, underscoring the positive impact of sustainable road construction practices and the allocation of adequate maintenance funds. The establishment of relationship between road steadiness and maintenance funds was established through a regression value of R2=0.94. This statistical correlation is represented by the equation y= 90.521 + 0.022x, providing a quantitative understanding of how maintenance funds influence road steadiness. The insights obtained from the outcomes of road steadiness modeling reiterate the significance of investing in additional routes and ensuring sufficient maintenance funds to improve performance.

Aspect-Level Sentiment Analysis through Aspect-Oriented Features
Authors: Busst Mikail Bin Muhammad Azman , Anbananthen Kalaiarasi Sonai Muthu , Kannan Subarmaniam 
Published: March 2024

Aspect-level sentiment analysis is essential for businesses to comprehend sentiment polarities associated with various aspects within unstructured texts. Although several solutions have been proposed in recent studies in sentiment analysis, a few challenges persist. A significant challenge is the presence of multiple aspects within a single written text, each conveying its own sentiments. Besides this, the exploration of ensemble learning in the existing literature is limited. Therefore, this study proposes a novel aspect-level sentiment analysis solution that utilizes an ensemble of Bidirectional Long Short-Term Memory (BiLSTM) models. This innovative solution extracts aspects and sentiments and incorporates a rule-based algorithm to combine accurate sets of aspect and sentiment features. Experimental analysis demonstrates the effectiveness of the proposed methodology in accurately extracting aspect-level sentiment features from input texts. The proposed solution was able to obtain an F1 score of 92.98% on the SemEval-2014 Restaurant dataset when provided with the correct set of aspect-level sentiment features and an F1 score of 95.54% on the SemEval-2016 Laptop dataset when provided with the aspect-level sentiment features generated by the aspect-sentiment mapper algorithm.

Sublime suspense: anomalias góticas em “A faixa malhada”, de Doyle
Authors: Matias Marcus , Gomes Júlia 
Published: March 2024

No presente trabalho, realizamos uma descrição dos conceitos referentes ao gênero gótico e ao gênero detetivesco, com os quais buscamos fundamentar a análise do conto “A faixa malhada”, de Sir Arthur Conan Doyle, publicado em 1892, a chamada Era de Ouro das produções detetivescas. Assim, o objetivo dessa pesquisa é demonstrar e evidenciar como a atmosfera provocada pelos elementos góticos causam na narrativa detetivesca de Doyle um efeito de estranhamento, enfatizando o uso do intelecto, característico das obras de detetive, ao mesmo tempo em que imprime um ar de incerteza ao conto. Para alcançar os objetivos dessa análise, nos baseamos, como principal referencial teórico, em Bloch (1998), Rossi (2008), Sá (2019), Vinícius (2013) e Murano (2011). Com base em nossas argumentações, é possível concluir que o conto “A faixa malhada”, faz uso de elementos da literatura gótica de maneira expressiva, influenciando, de certa forma, a perspectiva de leitura, devido ao alinhamento estrutural e temático dos gêneros detetivesco e gótico.
