Authors: Syakuro Billah Muhammad Abdan , Rizqi Akhmad Wasiur , Jufriyanto Moh.
Published: December 2023

PT. XYZ is a PT engaged in general contracting, outsourcing, trading and services. In the company there are several workers who had work accidents. According to existing data for 2021-2022 in fabrication work, most accidents are related to negligence of workers at PT. XYZ, namely in the grinding process from being cut to tripping over cables, so the authors conducted this research aiming to reduce and minimize work accidents of workers in the workplace. This research was conducted by measuring accidents in every activity at PT. XYZ. Data processing is done by calculating the level of risk assessment, then determining the level of efficiency to be achieved using the Job Safety Analysis (JSA) method. The results of the risk assessment for each job show that there is one highest level of risk, namely in the drilling section with a likelihood value of three and a severity level of four. From the results of risk control in the fabrication process, it can be carried out by means of technical control (repairing or adding technical equipment such as installation Occupational Health and Safety signs), administrative control (briefing before work, using special tools to lift materials), and using PPE. Proposed improvements that can be given are the addition of several personal protective equipment suitable for work at the fabrication site, namely the use of gloves, wearing masks, gloves, safety shoes and welding goggles. From the results of risk control in the fabrication process, it can be carried out by means of technical control (repairing or adding technical equipment such as installing K3 signs), administrative control (briefing before work, using special tools to lift material), and using PPE.

МАТЕМАТИЧНА МОДЕЛЬ СПОЛУЧЕНИХ ПРОЦЕСІВ ДЕНІТРИФІКАЦІЇ ТА ВІДНОВЛЕННЯ СУЛЬФАТІВ В ІННОВАЦІЙНОМУ БІОФІЛЬТРІ
Authors: Борисов Іван , Гевод Віктор
Published: December 2023

В роботі із застосуванням математичного моделювання розкрито особливості біологічного перетворення нітратів і сульфатів до нітрогену та сірководню під дією гетеротрофних денітрифікаційних і сульфат-відновлювальних бактерій в малогабаритному заглибному біофільтрі при різних співвідношеннях «карбон/нітроген». Технологія біофільтрації дає змогу виробляти питну воду більш екологічно безпечним, економічним та ефективним способом. Однак підземні води, окрім небезпечних для здоров’я людини нітратів, містять й інші неорганічні сполуки (солі важких та полівалентних металів, карбонати, сульфати і т. д.), що беруть участь у супутніх процесах (метаногенезу, сульфат-відновлення, уреолізу) в біофільтрі. Під час дослідження було розкрито додаткові можливості денітрифікаційного малогабаритного заглибного біофільтра, а саме, біотрансформації разом із нітратами сульфатів до сірководню, який може сприяти видаленню іонів важких та полівалентних металів з води. Досліджено зрушення сульфат-сульфідної рівноваги у водному середовищі біофільтра та вплив концентрацій сульфат-іонів і субстрату бактеріального живлення, зокрема етанолу, на накопичення і його витрачання в об’ємі біофільтра при здійсненні біофільтраційної денітрифікації. Результати моделювання сполучених процесів денітрифікації води у малогабаритному інноваційному біофільтрі у присутності сульфатів дали змогу встановити можливість і чинники їх керованого відновлення. Показано, що перевищення дозування субстрату живлення (етанолу) у вихідну воду порівняно зі стехіометричним, коли «карбон/нітроген» дорівнює 0,94, призводить до появи у фільтраті сірководню, який продукують сульфат-відновлювальні бактерії за рахунок живлення залишками етанолу. Сірководень у фільтраті не з’являється при дозуванні субстрату живлення у вихідну воду в кількості, що відповідає показнику «карбон/нітроген» меншому, ніж потребує стехіометрія біологічного відновлення нітратів. Кероване відновлення сульфатів до сірководню може бути корисним додатковим інструментом поліпшення якості фільтрату при сумісній денітрифікації і вилученні з води домішок солей важких металів. Розроблена модель і отримані результати можуть бути використані для подальшого поліпшення якості одержуваного біофільтрату за рахунок додаткового видалення з нього домішок солей важких і полівалентних металів.

З плином часу зростає комплексність загроз, які можуть здійснюватись проти критичної інфраструктури, включаючи кібератаки, великомасштабні відмови, терористичні акти тощо. Конфіденційність даних, які обробляються і передаються в межах критичної інфраструктури, є основним аспектом її безпеки. Традиційні методи криптографії, хоча і надійні, стають уразливими перед сучасними обчислювальними та квантовими здатностями атакуючих. З цієї причини актуальність вивчення та застосування квантової криптографії в критичній інфраструктурі набуває все більшого значення. Вони мають високу стійкість до атак, пов’язаних з обчислювальними аспектами, і забезпечують невідслідковуваність ключів і даних завдяки принципам невизначеності. Однак вони також вимагають складної технічної реалізації та подальшого дослідження для широкого впровадження. Квантова криптографія може забезпечити надійний захист від сучасних та майбутніх атак, зберігаючи конфіденційність даних та ідентифікацію користувачів. Проте важливо правильно підібрати методи та засоби для забезпечення максимального рівня конфіденційності даних з урахуванням особливостей мережі. У статті детально описано процеси вдосконалення протоколу квантового розподілу ключів за допомогою методів квантової ідентифікації та мультиплексування квантових каналів, описано математичний апарат вдосконаленого методу та визначено етапи формування стеку протоколу розподілу ключів. Запропонований вдосконалений метод квантового розподілу ключів формує можливість універсального його застосування в умовах невизначеності, забезпечуючи швидкодію виконання операцій та більший рівень захищеності даних.

Emblems of Faith: Holy Companions on the Road to Observance
Authors: FLOREA Carmen
Published: December 2023

The present study focuses on the specific devotional models that were promoted by the Observant Dominican friars in the late Middle Ages. By closely investigating textual and visual sources, previous research has noted that the reformed friars were eager to disseminate, particularly within the communities of the Observant Dominican women, the cult for the Passion of Christ and cults of saints that were easily transformed into models that pious women would adopt and emulate. Since the Observance was an European phenomenon and strong contacts existed between local friars and influential centres of reform, the prerequisites of the Dominican forma vitae became the standard according to which the communities of Observant Dominican women were organized and functioned. An integral part of this process of standardisation concerned the holy companions of the pious women affiliated to the Order of the Friars Preachers, who were usually recruited from the same cohort of saints represented by the Virgin Martyrs.
Rezumat: Studiul de față investighează modele devoţionale care au fost promovate cu predilecție de către Dominicanii Observanţi în perioada evului mediu târziu. Analiza detaliată a surselor textuale şi vizuale produse în ambianță observantă a evidențiat faptul că devoţiunea cristocentrică şi cultele unor sfinţi care puteau fi ușor transformate în modele imitabile au fost susţinute şi diseminate de către fraţii dominicani, îndeosebi în comunităţile călugăriţelor dominicane observante. Mişcarea observantă, un fenomen european, a facilitat răspândirea unor formule specifice care caracterizau modul de viață în cadrul ordinului, de multe ori intermediarii acestei diseminări fiind fraţi din regiune care au studiat în centre ale reformei observante (universităţi sau conventuri). Procesul de uniformizare și standardizare care a organizat mănăstirile călugăriţelor dominicane a inclus şi adoptarea unor culte specifice, integrate modelului de sanctitate virginală şi martirală.

Hans-Urs von Balthasar – la théologie de la culture entre la théologie transcendantale et la théologie esthétique
Authors: BUZALIC Alexandru
Published: December 2023

Hans-Urs von Balthasar – the Theology of Culture between the Transcendental Theology and the Aesthetic Theology. Von Balthasar is a theologian of the 20th century who proposes an approach in the continuity of patristic traditions and schools of Christian philosophy through a translation of the concept of revelation in a language that sends us towards the aesthetic experience. God, the union of the absolute values Verum and Bonum manifests itself through a theophany that brings out the transcendental category of Pulchrum. God reveals his Glory, the aesthetic experience becoming a mystical, natural contemplation, by understanding the history of salvation as a Theo-drama that is completed by the "end game" of salvation and the fulfillment of the eschaton.
Canonical Reflection on the Impact of Dolus on Juridical Acts in the Pio-Benedictine Code of Canon Law
Authors: GIURGI Eduard
Published: December 2023

It is well known that in many respects the 1917 Code of Canon Law, also known as the Pio-Benedictin Code of Canon Law, is an important source for understanding canonical legislation of the 1983 Code of Canon Law. This is also true when it comes to canonical legislation concerning juridical acts as well as that concerning the impact of dolus on juridical acts. It is for this very reason that the aim of the present paper is to provide a reflection on the impact of dolus on legal acts in the light of the legislation of the 1917 Code of Canon Law. The starting point for the reflection is the general norm on the impact of dolus on legal acts, which is laid down in canon 103, § 2 of the 1917 Code of Canon Law. As is well known, canon law in general does not contain definitions of the terms used. This is also true when it comes to dolus. The 1917 Code of Canon Law does not provide a definition of dolus, but entrusts this task to canonical commentators. Canonical literature has developed several definitions of dolus, which are included in this paper. The work also contains an analysis of the essential elements of dolus, then continues with a presentation of the division of dolus and the legal effects of dolus on juridical acts. All this contributes to a good understanding of dolus and its impact on legal acts in the Code.
Entre el orientalismo periférico y el occidentalismo
Authors: Cuadro Mariela , Frenkel Alejandro
Published: December 2023

El artículo analiza, desde un enfoque comparativo y descriptivo, la (P)política (E)exterior de la Argentina hacia los países de Medio Oriente, tomando como casos de estudio los gobiernos del Frente para la Victoria (2003-2015) -con especial énfasis en los gobiernos de Cristina Fernández de Kirchner- y de la Alianza Cambiemos (2015-2019). Con este fin, se indaga en las concepciones del mundo de cada uno de los gobiernos y los modos de relacionarse con él, sus lecturas específicas sobre la región de Medio Oriente, y las políticas hacia esta región en temáticas específicas: comercio internacional, países del Golfo y el conflicto palestino-israelí (el cual aparece vinculado a la cuestión Irán). Como hallazgo, el texto demuestra que, a pesar de los discursos antagónicos sobre el “modelo de país”, la concepción del mundo y las diferentes estrategias de Política Exterior que hubo en cada etapa, pueden vislumbrarse tanto continuidades como discontinuidades. Por caso, si bien el discurso del orientalismo periférico -que esencializa negativamente a Medio Oriente- fue un punto en común de ambos gobiernos, la política exterior de Cambiemos combinó un orientalismo periférico con un firme occidentalismo.
La evaluación como práctica emancipatoria: excepcionalidad pedagógica y trabajo docente
Authors: Alonso María Lorena , Ardini Claudia Gabriela
Published: December 2023

El presente artículo recupera la experiencia formativa, desarrollada desde la Asociación de Docentes e Investigadores de la Universidad Nacional de Villa María (UNMV) en 2021, acerca de la evaluación en el contexto de excepcionalidad pedagógica y más allá de ella: su sentido y su objeto, sus límites y alcances, su dimensión política y sus formas. Algunas reflexiones surgidas en ese marco dieron lugar tanto al replanteo de estrategias pedagógicas relacionadas con la práctica evaluativa como a la apertura para pensar y diseñar evaluaciones novedosas y creativas, junto con la revisión del modelo pedagógico subyacente en los instrumentos de evaluación tradicionales. La reflexión abre también a las condiciones en las que las y los docentes enfrentan situaciones que rebasan su práctica laboral y profesional y buscan respuestas en el ámbito más extenso del sistema educativo.

The relative effect of trade and tax reforms on import tax revenues in Ghana
Authors: Brafu-Insaidoo William Gabriel , Obeng Camara Kwasi , Ewusie Ewura Adwoa
Published: December 2023

This study examines the relative effects of alternative import policy reform features and value added tax on import tax revenues in Ghana. To achieve this objective, the study first estimates the effect of alternative import policy features and VAT on import tax changes. The estimated coefficients are then applied to the observed values of each respective import policy feature and VAT to obtain the contribution of each policy feature to change in import tax revenue. The study concludes that Ghana has made some revenue gains by reducing the average official duty rate and imposing VAT rate on imports, and that revenue gains have outstripped revenue losses from the reforms. It is subsequently suggested that the government should maintain the current strategy of replacing tariffs with a type of consumption tax.

Published: December 2023

Background: Breast cancer patients experience a variety of psychological symptoms such as anxiety, depression that affect their quality of life. The present study probed whether the socioeconomic status had any significance on psychological distress and quality of life of breast cancer patients in India.Method: This was a cross-sectional and observational study, conducted over 111 breast cancer patients in a tertiary cancer hospital, Kolkata. Subjects were eligible to participate and they were of over 23rd years of age and had a histologically confirmed diagnosis of breast cancer had no history of recurrence or metastasis, and had no previous psychological problems. Age, marital status, residence, education, occupation and family income were assesses for patients’ socio economic status. Psychological symptoms and quality of life were assessed by using validated tools. Means and standard deviations of each outcome were compared by socioeconomic status and multivariate linear regression models for evaluating the association between socioeconomic status, psychological distress and quality of lifeResults: The patient group was categorized into three groups based on their income level as follows: ≤500=27.9%), 500-1000=51.4% and high income = ≥1000=20.7%. A total of 111 breast cancer patients participated in the study; the mean age of participants was 49.7 (SE=1.31).After using multivariate logistic regression with fully adjusted models, the patients who were living alone had significantly higher level of depression and poor quality of life compared to those who are employed. Higher education and family income both positively associated with quality of life after adjusting for age, marital status and occupation.Conclusion: The findings revealed that the family income have a significant impact on the psychological distress of the cancer patients.
Resolution of hypoalbuminemia in a 3-year-old hound-mix dog after discontinuation of oclacitinib
Authors: Parvathy Karthika
Published: December 2023

OBJECTIVE

Albumins are protein molecules that account for 50% of total plasma protein. They are imperative in maintaining intravascular colloidal oncotic pressure, act as key scavenger molecules for oxygen free radicals, and perform a major role in transporting numerous substances and in wound healing. Hypoalbuminemia has been reported as the consequence of decreased intake, increased loss, decreased production, and redistribution. While anecdotal evidence of tyrosine kinase inhibitors causing hypoalbuminemia in canine patients exists, to the author’s knowledge there is no formal report to this effect to date. This case report aims to bridge the gap between anecdotal evidence and literature.

ANIMAL

3-year-old neutered male hound-mix canine.

CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES

The patient was presented for recurrent otitis externa refractory to treatments with orbifloxacin/mometasone/posaconazole otic suspension, miconazole/polymyxin B/prednisolone otic suspension, ketoconazole/TrizEDTA, and gentamicin/mometasone/clotrimazole, which prompted consideration of oral antifungals. Baseline blood work prior to initiation of fluconazole showed elevated alkaline phosphatase. Treatment was initiated with fluconazole, and blood work was rechecked and revealed hypoalbuminemia. Multiple diagnostic tests failed to reveal a cause of hypoalbuminemia.

TREATMENT AND OUTCOME

Discontinuation of oclacitinib that the patient was being administered resulted in normalization of serum albumin.

CLINICAL RELEVANCE

It is unclear whether hypoalbuminemia associated with oclacitinib administration is associated with worse outcomes for pathologies in canine patients; however, this seems to be the case in humans according to some reports. This report aims to take a step in the direction of this knowledge.

Sensorless Control of PMSM in Low Speed Region Using HF Pulse Signal Injection Method
Authors: Petro Viktor , Kyslan Karol
Published: December 2023

The sensorless control of the permanent magnet synchronous motor (PMSM) has attracted wide attention due to its economic and safety benefits. A fast and high-precision rotor-position estimation is necessary for the implementation of sensorless control. In low-speed region, high frequency (HF) signal injection methods are mostly adopted. They suffer to bandwidth deterioration as some digital filters must be included in the current feedback loop or the speed observation signal processing. The HF signal injection method based on the injection of voltage pulses is presented in this paper together with its implementation in MATLAB/Simulink. The method is based on the injection of voltage pulses where injection itself is separated from the motor control algorithm. The simulation results show that the proposed method has good dynamic performance for the sensorless control of PMSM.

Published: December 2023

Insulators, as the main insulating element of transmission lines, are exposed to various stresses, which affect the operation and thus the reliability of electricity supply. To improve the reliability of insulators, it is necessary to monitor their condition. Thanks to the development of computer technology, it is possible to process a large amount of data, which popularizes the possibility of diagnostics online. Factors that affect reliability, failure rate, and losses the most, are pollution and humidity. Our research is focused on monitoring and evaluating the applicability of various sensing electrodes for measuring leakage current on glass insulators. Relative humidity and pollution levels changes can give us a clear view of the used measuring method and how different sensing electrodes can affect the value of leakage current.
Spark-Based Digital Factory Design
Authors: Pölöskei István
Published: December 2023

Big data processing often uses the paradigm of parallelism by computing directly on top of the distributed data storage. The existing big data workflows unify the data processing practices to utilize the cloud’s native computational potentials to offer advanced machine learning and BI capabilities. Spark is an open-source massively parallel in-memory data processing framework, the current state-of-the-art. The primary approach is to break down the job into granular-level executed tasks, enabling parallelization. In the discussed case study, through IoT – cloud solutions, the plant data can be converted into an analyzable form to let the farther machine learning modules produce added value. To maximize the efficiency of the processing and accumulation, cloud-based components are introduced. Based on the data insights, the appropriate operative actions can be taken. The cost and performance optimization methods were also discussed in the study. Through achieving higher degree of digitalization, the control over the production increased.
Hydraulic Turbine Modelling Including a Fuzzy Model of Efficiency
Authors: Perduková Daniela , Fedor Pavol , Fedor Marek
Published: December 2023

The hydraulic turbine is considered as a heart of the hydropower plant because of its important function in the whole process of electrical energy production. Turbine´s efficiency calculation is analytically demanding and dependent on parameters that are often obtained only by a theoretical estimation. Therefore, using its accurate model, which takes into account its efficiency, is necessary to achieve realistic and relevant results. The article briefly surveys current knowledge and methods of designing the hydraulic turbine model. The new idea consists in that a fuzzy system was used to create turbine´s efficiency model based on a measured operating data of the turbine flow rate and its mechanical speed without any need of knowing exactly the turbine parameters. Such a model can be used in the design and development process of an optimal energy control of a hydraulic turbine, as well as in the effective process of determination the actual turbine’s wear rate. The achieved results were obtained using the computational tools of the Fuzzy Toolbox in the MATLAB.

Strategies for Safeguarding Intangible Cultural Heritage of Yi Ethnic Groups in the Context of Informatization and Its Practice in Regional Culture
Authors: Zhang Dehua , Wuda Pan
Published: December 2023

The digitization of intangible cultural heritage provides the basis for its protection and inheritance. In this paper, we extracted the classes and interrelationships corresponding to each element for the content of Yi Intangible Cultural Heritage, constructed the data model and accomplished the relationship abstraction of different classes. Based on the structure of different data classes, the correlation between spatial change and non-heritage status is explored. The data model is proposed to cluster non-heritage data based on SWC-WMD distance, which improves the similarity calculation based on WMD distance. The association analysis of non-heritage item classes was performed using Yi folk dance as an example, and the overall non-heritage data was analyzed by clustering. In Yi folk dance, the association formed a network correlation graph with N2, N3, and N12 as the three main centers, in which the dance class items associated with N2, N3, and N12 were 9, 9, and 8, respectively. Mining out the relationships among NH items helps to better the overall NH protection.

Secondly, probability theory and graph theory are utilized to deal with uncertain information and reduce the meta-multiplicity of the analysis of uncertain knowledge. Then, the Bayesian network structure learning problem is analyzed, and a constraint-based structure learning method is proposed to score students’ qualities by a given scoring function, and using a search algorithm, the best scoring network structure is searched. Finally, in order to analyze the influence of the Civics curriculum on the quality of students in college A, we should analyze the impact of the curriculum. The results show that from the innovative quality of students, the distribution density of innovative habit and innovative ability scores in the interval of 70~75 is (0.02, 0.035), and the distribution density of innovative consciousness scores in the interval of 70~86.25 is (0.005, 0.07). The data show that curriculum Civics can effectively promote the cultivation of innovative talents and the construction of an innovative country by internalizing the quality of innovation in the heart and externalizing it in the form of cultivating students’ innovative habits, improving their innovative consciousness and enhancing their innovative ability.

Authors: Jianhua Du
Published: December 2023

This paper starts with the application of hyper-convergence technology, builds the framework of a university smart campus based on it, and gives the framework description of the smart campus. In order to analyze the network security for the smart campus, the Markov model is used as the basis combined with the reinforced Q learning algorithm for network node security detection, and a specific simulation analysis is given. The encryption performance and defense performance of the elliptic curve cryptosystem are analyzed through the elliptic curve cryptosystem to formulate the encryption scheme for students’ private data in the smart campus. The results indicate that the Markov model node detection combined with reinforcement Q-learning in this paper takes a maximum time of about 5.75s when the network node size reaches 150. When the number of nodes in the smart campus network is 30, under brute force attack, the whole network is captured only when the number of malicious nodes increases to more than 22, while under random attack, it takes as many as 30 malicious nodes to join before the network completely falls. This illustrates that the use of the Markov model can be realized to analyze the network security of the smart campus and that student privacy protection needs to further improve the awareness of student data privacy protection and develop the habit of assessing the privacy risk beforehand in their daily network behavior.

Authors: Guo Shanyu
Published: December 2023

Since the traditional vocal music course cannot meet the learning objectives of current music majors, this paper explores the reform of vocal music courses by combining modern multimedia technology. First, the teaching experience brought by immersive multimedia technology is explored, and based on the spatial and temporal features of the interactive behavior of the vocal music online course are extracted by the convolutional neural network, and multimodal fusion is carried out by combining linguistic features. Then, the GCN-LSTM network is used to model its spatial structure information and long temporal dependency, based on the joint learning of multimodal features, and then identify the interactive behavior. Finally, after constructing the teacher-student features, the extraction effect, recognition effect, and interactivity results of the behavioral features of the vocal online course are analyzed. The results show that the overall teacher-student behavioral feature extraction is above 0.7, except for “writing” with an accuracy of 0.76, “speaking”, and “listening”. The recognition effect of the overall teacher’s behaviors is more than 0.73, and in the range of 100s~250s, students “raise their hands” frequently and interact more. The students “raised their hands” frequently in the 100s~250s and interacted with each other more frequently.

Authors: Zhao Bi
Published: December 2023

This paper constructs a Bayesian network text recognition model based on the Bayesian network and explores the role of Chinese language literature in the dissemination of traditional culture by analyzing the embodiment of traditional culture in Chinese language literature network texts. The collection process of Chinese language and literature data in network text is analyzed from the perspective of textual data interaction. The information of node variables in a Bayesian network is used to determine the mutual relationship between Chinese language literature and traditional culture. The degree of interdependence between Chinese literature and traditional culture can be measured by combining mutual information. The results show that the correct rate of text recognition of the Bayesian text recognition model decreases slightly when the training samples are (100-300), but the correct rate always stays around 0.85, thus reflecting the effectiveness of the network recognition model in this paper. Chinese language literature has a certain role in the dissemination of traditional culture, which proves that Chinese language literature, as a carrier of traditional culture, can improve the dissemination speed of traditional culture. This study focuses on the integration of Chinese literature and traditional communication to improve a new vision.
