Authors: Demirel Tuncer , Yağmur Selçuk , Kayır Yunus , Kurt Abdullah
Published: December 2023

Threading with taps is a method frequently used in machining. Since this process takes place in a closed area due to its nature, some difficulties are encountered. In this study, the results of a previous experimental work were compared with the results of a simulation program. In the experimental work, the tapping process were performed by using M10 taps with three different geometries for the drilled holes on AISI 1050 material. Tapping operations were carried out with uncoated and TiN coated HSS tools.
For the simulatin program, the 3D CAD models of the tested taps were created by reverse engineering method and then imported into a simulation program, called Third Wave AdvantEdge program. The CAD models were evaluated by Third Wave AdvantEdge program based the finite element method. The thrust force, torque, chip formation occurring during the threading process were examined. It was concluded that the simulation and the experimental results were quite compatible.

Technical Solutions to Reduce the Amount of Dust Particle Breakthrough when Cleaning Emissions from the Production of Reinforced Concrete Products Using Dust Collectors with Counter Swirling Flows
Authors: Meskhi B. Ch. , Evtushenko A. I. , Borovkov D. P.
Published: December 2023

Introduction. The production of reinforced concrete products, being the basis of modern industrial construction, is a very significant source of dust emissions. Traditional cleaning methods are often unable to ensure the compliance with air quality requirements, and replacing them with more modern ones requires significant capital and operational costs. One of the most promising ways to solve the problem is the use of a new class of inertial dust collectors with counter swirling flows, combining constructive simplicity and low operating costs with sufficiently high work efficiency.

   The aim of the work was to analyze the factors influencing the magnitude of the breakthrough coefficient of fine dust particles, as well as the development of constructive solutions aimed at reducing it.

   Materials and Methods. An analytical review of technical solutions aimed at reducing the breakthrough magnitude was carried out, on the basis of which the designs of the lower input of dust collectors with counter swirling flows were developed. Methods of computational experiment and field measurements were used to confirm the effectiveness of the developed structures.

   Results. By means of numerical experiments, the information about the aerodynamic flow pattern in the separation chamber of the CSF dust collector was obtained, and the breakthrough magnitude of dust particles was estimated. The solutions were developed for the design of the lower coaxial input of the swirling flow of dust collectors on the counter swirling flows, taking into account the features of dust pollution generated during the operation of technological equipment of reinforced concrete production.

   Discussion and Conclusion. The presence of a displacement of the axis of the secondary swirling flow from the axis of symmetry of the separation chamber was established. The consequence of this was the non-coaxiality of the primary and secondary flows, which led to a decrease in the intensity of the twist, the formation of parasitic vortices, and, as a consequence, an increase in the value of the breakthrough coefficient. This effect was especially pronounced with a large proportion of fine dust particles, characteristic of dust pollution formed during the production of reinforced concrete products. The proposed design of the coaxial input of the secondary swirling flow reduced the magnitude of this eccentricity, which made it possible to achieve a significant reduction in the breakthrough magnitude of fine particles characteristic of dust emissions of reinforced concrete industries. The results obtained can be effectively used both in the production of reinforced concrete products and in other branches of construction production, which is characterized by intensive formation of fine dust emissions.

Authors: Sufiyanova M. A. , Volokhina A. T. , Glebova E. V.
Published: December 2023

Introduction. Ensuring industrial safety (IS) is one of the priority goals of any company. It is obvious that achieving its high level is impossible without the formation of a safety culture among employees, since their wrong actions can lead to emergencies and death of people at hazardous production facilities. The concept of industrial safety culture (ISC) is interpreted in different ways, but all definitions are united by the need for employees to realize that industrial safety should become their main goal and internal need. To date, there are many methods for determining the degree of ISC development. They are actively and successfully used at many enterprises. At the same time, it should be noted that the Russian legislation lacks, in particular, a methodology for quantifying the industrial safety culture specifically at the enterprises of the oil and gas complex, which have their own characteristics and specifics. Therefore, the introduction of a new quantitative approach to assessing the effectiveness of management of industrial safety culture has important scientific and practical significance on the industry agenda.

   The aim of this work in this regard was to develop mechanisms to increase the ISC level at one of the gas transportation enterprises of the country based on the results of the survey of its employees.

   Materials and Methods. For the analysis, the results of a three-level questionnaire conducted in 2021 and 2022 were used, which included socio-biographical characteristics of employees, their assessments on specially developed 16 components of industrial safety, as well as the interview of focus groups on six selected IS components.

   Results. During the analysis of the questionnaires, an increase in the level of industrial safety culture was established from the predicted (third level) to the proactive (fourth level) according to the five-level classification of the International Association of Oil and Gas Producers (IOGP).

   Discussion and Conclusions. The comparative analysis demonstrated positive dynamics of the results of the ISC level assessment by the employees of the gas transport enterprise. Its increase at this enterprise was achieved through the introduction and implementation of proactive measures, such as the development of personal obligations of employees in the field of safety, their maximum involvement in the development of competencies in the field of industrial safety, ensuring openness / transparency of communications on safety issues, and the formation of a positive attitude of employees to changes in this area.

Published: December 2023

This study explores individual decisions in carrying out natural non-permanent mobility activities to the city of Bandar Lampung. Non-permanent migration increased by 300 percent during 2016-2018. The data used in this research is the 2018 Sakernas micro data for August. Data analysis using the Binary Logistic Regression. The findings show that the variation in the independent variable is able to explain the variation in the dependent variable by 52 percent.. All independent variables (age, wages, education, and distance) are statistically significant in influencing individual decisions to undertake non-permanent migration, except for the variable marital status. The highest odds ratio value for the distance variable, then the education variable. This means that the closer the distance to Bandar Lampung and the better the individual's education, the higher the probability of non-permanent migration to the city of Bandar Lampung. Variable selection is limited due to adjusting the supply of Sakernas micro data files. In the future, it is very important for the government to understand this temporary mobility movement in order to control the short-term and long-term implications of achieving a more equitable distribution of wealth in Lampung Province.  Equitable development between urban and rural areas needs to be realized immediately in reducing income inequality and development.

Published: December 2023

З кожним роком автори шкідливого програмного забезпечення створюють все більш досконалі та хитромудрі шкідливі програми, які можуть завдати шкоди нашим комп’ютерам. Традиційні методи, які ґрунтуються на пошуку сигнатур програм, перестають бути ефективними для вирішення проблеми детекції шкідливого програмного забезпечення. На зміну приходить автоматизація аналізу файлів, яка є більш перспективним підходом для виявлення підозрілих файлів. Для виявлення таких програм все частіше використовують методи машинного навчання. Однак для виконання своїх операцій такі рішення можуть потребувати багато обчислювальних ресурсів. Тому виникає задача створення оптимальної моделі машинного навчання з погляду швидкості навчання і точності детекції шкідливого програмного забезпечення. Крім того, зазвичай одного методу представлення даних недостатньо для якісного виявлення шкідливих ознак файлів. Тому в цій роботі буде описано два різні методи: один підхід ґрунтується на бінарній інформації файлу, другий полягає у використанні трасувальних інструкцій. Мета цієї роботи – підвищення ефективності виявлення шкідливого програмного забезпечення шляхом оптимізації методів вилучення ознак та застосування машинного навчання. Основні задачі дослідження включають: вилучення ознак з exe. файлів, створення кількох моделей машинного навчання та їх порівняння для визначення найефективнішої моделі. Використаний у цьому дослідженні набір даних був зібраний з різних інтернет-джерел та складається з 12824 виконуваних файлів у форматі .exe, з яких 11844 файлів є шкідливими, а 980 – доброякісними. У статті представлено рекомендовані методи вилучення ознак та генерації вхідних даних для моделей машинного навчання на основі алгоритму машини опорних векторів. Ці методи дозволяють знайти найкращий шлях для обробки ознак, що описують шкідливий файл. Було створено шість моделей машинного навчання, кожна з яких показала високі показники метрик F-score, precision та recall. Модель, яка була створена на основі бінарного типу представлення даних, показала найвищі результати по всіх метриках.

GOVERNMENT STATISTICS ON CITIES OF VOLYN PROVINCE (UNTIL THE 1870S)
Authors: Karlina Oksana
Published: December 2023

Statistical editions of the 19th century (until the 1870s), which contain information about Volyn cities, were considered. The stages of the formation of state statistics in the Russian Empire in the context of data collection on urban settlements and the urban economy were singled out. We analyzed in detail the content of statistical sources issued by the Ministry of Internal Affairs and indicated the features and shortcomings of each of these publications. It was noted that the first work of the statistician Karl German was a historical-statistical research of a compilative nature. More extensive statistical information about urban settlements (including those in the Volyn province) was contained in a publication prepared under the leadership of Matvyi Shtern. It served as a foundation for future collections that were printed in the 1830s and 1840s. The urban population's statistical information has been summarized in tabular form. The statistical tables published in 1858 include a wide range of materials about the cities of socio-economic and cultural content, the reliability of which is based on the annual reports of the governors to the emperor. It was emphasized that in the next edition, the compilers did not limit themselves only to compiling tables but also conducted a thorough analysis of them. According to the article, the reform of city administration needed planning work from the central government to gather information about the city's economy. As a result, this led to the creation of two voluminous statistical reference books, which are valuable sources for studying the history of cities before the reform of 1870. It was supplemented by detailed information about the city economy at the beginning of the 1860s contained in another publication prepared by the Ministry of Internal Affairs. It was noted that a researcher dealing with urban issues of the first half of the 19th century must consider the heterogenic, incomplete, and incorrect nature of statistical information due to the lack of consistent practice of keeping state statistics in the Russian Empire. At the same time, statistical sources remain very significant for historical urbanism.
ARCHBISHOP ADAM (PHILIPOVSKY): NEW DOCUMENTS ABOUT HIS VISIT TO SUBCARPATHIAN RUS
Authors: Danylets Yurii
Published: December 2023

In the article, for the first time, documents about the visit of Bishop Adam (Philipovsky) to Subcarpathian Rus in June 1926 are introduced into scientific circulation. The author was involved in the analysis of sources from several archives of different countries. Among them are the documents of the State Archives of the Transcarpathian Region, the National Archives of the Czech Republic, and the Archives of the Office of the President of the Republic in Prague. The epistolary legacy of the Czech bishop Gorazd (Pavlik), which is kept in the Archives of the Olomouc-Brno Diocese in Olomouc, is also of some interest. Periodicals also supplement documentary sources. The article uses a publication from the Uzhhorod newspaper «Novoje vremja», which was published in Latin. The text provides a brief description of the life path of Bishop Adam, and his connections with individual residents of Subcarpathian Rus are reflected. The author emphasizes that the activities of the aforementioned bishop played an essential role in the life of American Orthodoxy in the first half of the 20th century. The study of Philipovsky's biography gives grounds for asserting that his work is not sufficiently studied historiographically, and historians do not even mention the visit to Subcarpathian Rus. The author traces the development of Adam Philipovsky, his educational level, and his professional activity. It is emphasized that he was a graduate of Lviv University, engaged in journalism, and later went through all levels of the priestly career. The initiator of his ordination in 1922 was Bishop Stefan (Dzubay) of Pittsburgh, who wanted to strengthen his position in Canada in a confrontation with Metropolitan Platon (Rozhdestvenskyi). Bishop Adam led the communities of Carpathians who lived in several Canadian cities and then extended his jurisdiction to American parishes of the «old land» as well. Having lost to the metropolitan and received a ban from the ROCOR, the bishop left behind a significant influence and achieved recognition of his diocese by the Karlovy Vary Synod. Several documents from the SATR funds are attached to the article, which characterizes the policy of the Czechoslovak authorities towards the Orthodox Church and describes the course of the bishop's visit to Subcarpathian Rus.
For the time Being: Heidegger’s Final Words in Vorläufiges I-IV
Authors:   North-West University Potchefstroom, South Africa, Schrijvers Joeri
Published: December 2023

This article discusses the final volume of Heidegger’s Gesamtausgabe. It does so by contextualizing its main themes, that is, by relating it to other writings of Heidegger of roughly the same period. Three such themes can be discovered in Heidegger’s “final” writing: a discussion of the nature of phenomenology, the abandonment of the ontological difference and the relation between the thought of being and the discipline of theology. The essay concludes with a comparison of Heidegger’s thinking of Ereignis to how theology configured the relation between God and the human being, so arguing that Heidegger seemed more indebted to the tradition of theology that he at times could acknowledge.
Critique of Supernatural Revelation
Authors:   North Phoenix Preparatory Academy, Nemes Steven
Published: December 2023

This article argues that the claim of traditional Christian theology and religion to be in possession of supernatural revelation cannot be substantiated in a valid and non-circular manner in principle. It then notes the consequences for theology if the notion of supernatural revelation is abandoned. It proposes agnosticism about unknowable matters as a way of exercising faith or trust in the limits God’s providence has established for human knowledge.

However, like the other virtues, it is necessary to shape it along with the development and growth of spiritual life. The article will discuss threads of hope from the theological perspective and spirituality, both from the point of view of Catholic theology but also from the point of view of human psychological development. Hope will be analyzed from a theological, moral and biblical perspective, and its meaning, importance and universality will be indicated. Then, the process of shaping human spirituality will be described: its importance from a theological perspective, and the individual stages of spiritual development will be presented from the perspective of developmental psychology and the psychology of religion. The last part will present contemporary research on the relationship between hope and human spirituality as well as perspectives on further research directions.
The role of life cycle assessment in the implementation of 1 circular economy in sustainable future
Authors: Ledakowicz Stanisław , Ziemińska-Stolarska Aleksandra
Published: December 2023

Life Cycle Assessment (LCA) is an important tool of Circular Economy (CE), which performs the analysis in a closed loop (“cradle-to-cradle”) of any product, process or technology. LCA assesses the environmental threats (climate change, ozone layer depletion, eutrophication, biodiversity loss, etc.), searches for solutions to minimize environmental burdens and together with CE contributes to reducing greenhouse gas emission, counteracts global climate crisis. The CE is a strategy for creating value for the economy, society and business while minimizing resource use and environmental impacts through reducing, re-using and recycling. In contrast, life cycle assessment is a robust and science-based tool to measure the environmental impacts of products, services and business models. Combining both the robustness of the LCA methodology and the principles of circular economy one will get a holistic approach for innovation. After a presentation of the LCA framework and methods used, 27 examples of case studies of comparative LCA analysis for replacement materials to reduce environmental load and their challenges as assessment methods for CE strategies are presented. It was concluded that there is a need for improvement of existing solutions, developing the intersection between the CE and LCA. Suggestions for developing a sustainable future were also made.
Increase of energy self-consumption in hybrid RES installations 1 with PV panels and air-source heat pumps
Authors: Pater Sebastian
Published: December 2023

In recent years, European countries have experienced a noteworthy surge in the interest surrounding renewable energy sources, particularly the integration of photovoltaic (PV) panels with various types of heat pumps. This study aims to evaluate the energy performance of a grid19 connected hybrid installation, combining a PV array with an air-source heat pump (AHP), for domestic hot water preparation in a residential building located in Cracow, Poland. The primary focus of this evaluation is to assess the extent to which self-consumption (SC) of energy can be increased. The study utilizes Transient System Simulation Tool 18 software to construct and simulate various system models under different scenarios. These scenarios include building electricity consumption profiles, PV power systems, and the specified management of AHP. Analyses were conducted over a period of 1 year to assess the operational performance of the systems. In the considered installations, the differences in SC values between PV installation ranged from 9 to 25%. Notably, the highest SC values were observed during the winter months. AHP with operation control allows to obtain in some months of the year up to 35% higher value the SC parameter compared to systems without AHP. The highest annual 29 SC value recorded reached 83.9%. These findings highlight the crucial role of selecting an appropriate PV system size to maximize the SC parameter.
Veterinary clinicians prefer template-style reports with personal confidence estimates for cytologic sample evaluations
Authors: Rishniw Mark , Freeman Kathleen P.
Published: December 2023

OBJECTIVE

To examine preferences of veterinary clinical pathologists, clinicians, and students for cytology report formats.

SAMPLE

24 clinical pathologists, 1,014 veterinarians, and 93 veterinary students who were members of the Veterinary Information Network.

METHODS

Members of the Veterinary Information Network responded to an online survey invitation, made available between July 11, 2023, and July 24, 2023. Respondents were randomly directed to 1 of 4 sets of cytology reports, each containing a traditional narrative format, narrative format with terms expressing a degree of confidence and associated numerical ranges, and template format with similar estimates of confidence. Respondents ranked the reports in order of preference and then provided comments about their top-ranked choice. Responses were analyzed mostly with descriptive statistics or comparisons of proportions.

RESULTS

14 of 24 clinical pathologists preferred the traditional narrative format, whereas 449 of 1,042 veterinary clinicians and veterinary students preferred the template format. Respondents (460/1,131) ranked the template format as most preferred, but the narrative format with terms expressing a degree of confidence ranked highest overall. Many respondents appeared to misunderstand the degree of confidence estimates being expressed numerically. Respondents choosing each format often stated that their preferred choice was “easiest to understand” and “most comprehensive.”

CLINICAL RELEVANCE

Given the preferences of veterinary clinicians and veterinary students for a template format, clinical pathologists should consider modifying the way they report evaluations of cytologic specimens. Template formats should help standardize reporting of cytologic specimens, thereby improving communication between clinical pathologists and clinicians. However, both clinicians and clinical pathologists need to better understand the purpose of terminology expressing degrees of confidence in such reports.
Intestinal full-thickness needle-core biopsy via laparotomy is safe, rapid, and effective and less invasive than standard incisional biopsy in dogs and cats
Authors: Maggiar Adrien , Andréjak-Bénit Juliette , Miclard Julien , Sarran Delphine , Billet Jean-Philippe
Published: December 2023

OBJECTIVE

To describe the intestinal full-thickness needle-core biopsy technique via abdominal laparotomy outcomes and compare the histopathological and immunohistochemical diagnosis with standard incisional intestinal biopsy technique in dogs and cats.

ANIMALS

3 dogs and 17 cats.

METHODS

Client-owned dogs and cats were prospectively enrolled if intestinal full-thickness biopsies were indicated for the diagnosis of diffuse chronic intestinal diseases following ultrasonography. The study period extended from June 2021 to December 2022. All animals underwent intestinal biopsies with both techniques (needle-core biopsy and standard incisional biopsy) via abdominal laparotomy. Data collected included clinical signs, biopsy collection times, complications, and histopathologic and immunohistochemical findings. A minimum follow-up of 14 days was required.

RESULTS

The main clinical sign at presentation was chronic vomiting (65%). Mean needle-core biopsy collection time (262 seconds) was significantly shorter than standard incisional biopsy collection time (599 seconds; P < .000001). The incidence of minor complications was 10% (inflammation of the skin surgical site secondary to licking). One catastrophic complication occurred on a standard incisional biopsy site in 1 cat in a context of bile peritonitis (5% of all cases). There were no complications associated with the needle-core biopsy. All but 1 cat were discharged, with a median of 2 days (range, 1 to 4 days) after surgery. The diagnoses resulting from both techniques were 100% concordant for the distinction between inflammatory bowel disease and intestinal lymphoma via histopathology and immunochemistry.

CLINICAL RELEVANCE

Needle-core biopsy is safe, rapid, and effective and is less invasive than standard incisional biopsy.
Comparative Study Between Sliding Mode Controller and PI Controller for AC/DC Bridgeless Converter Under Uncertain Parameters
Authors: Almobaied Moayed , Musleh Ahmed Mosa
Published: December 2023

In this paper, a comparative study between nonlinear sliding mode controller (SMC) and standard PI controller for stabilizing bridgeless AC/DC converter under uncertain parameters is presented. This type of converters is widely used in harvesting low energy systems as in wind turbine, piezoelectric transducers and heat exchange transducers. Designing robust controllers to enhance the efficiency and accuracy of these converters has become a promising track in control engineering field. The traditional bridge rectifier is widely used in the majority types of AC/DC conventional converters to gain the rectified DC voltage from the low AC input voltage source. However, these traditional converters are not effective for the low output voltage of renewable sources due to the voltage drops across rectifier’s diodes. The proposed SMC-PI controller is used to enhance the stability and the response of these converters under uncertain parameters comparing with the standard PI controller. The proposed approach consists of both Boost and Buck-Boost converters with two controllers in order to maximize the useful output energy from the source. The graphical method has been used to obtain the limitation of the coefficients of the standard PI controller. A parameter space approach is used to find all robust stabilization PI coefficients and the stability regions. A comparative study using simulations in MATLAB is presented to ensure the effectiveness and robustness of the proposed SMC-PI controller under some external disturbances.

The Application of Digital Multimedia Technology in the Innovative Mode of English Teaching in institutions of higher education
Authors: Liu Yun
Published: December 2023

Innovative English teaching resources will inevitably result from the use of media technology in the classroom. This article will examine the new approach to teaching English in college from the standpoint of teaching resources. In order to establish a new mode of English teaching in higher education institutions based on personalized recommendation of teaching resources, this paper proposes two recommendation algorithms: one is content-based, and the other is collaborative filtering. The algorithm is enhanced by combining it with the design of multimedia English teaching resources. The influence of hit rate and MAE values prior to and following the cooperative filtering recommendation method is examined. The distinction between the pre-and post-test results of the experimental and control courses is analyzed and compared to conclude the examination of the impact of the novel model of teaching college English. The analysis indicates that the improved recommendation algorithm has a 4.85% higher hit rate than the traditional collaborative filtering algorithm. The improved recommendation algorithm is more accurate than the traditional recommendation algorithm, as suggested by this.

Authors: Wang Yongsheng
Published: December 2023

This paper adjusts the coupling model to analyze the variables in order to measure the degree of coupling between overseas alumni donation behavior and university strategies. The entropy weighting method is used for the determination of indicator weights and systematic, comprehensive evaluation function. The replicated dynamic equations of alumni entrepreneurs and colleges and universities are explored separately to verify the relationship between the probability of alumni donations, the probability of colleges and universities willing to accept donations and the probability of entrepreneurs’ willingness to donate. To simulate the impact of three types of university incentive strategies, namely, tax incentives, reputational gains, and networking resources, on the donation decisions of overseas alumni and to explore the ranking of the three types of incentive strategies in a single incentive strategy implementation environment. In order to explore the cooperative evolution process of multi-channel coupling, the group structure, size, degree of interaction and cognition are modeled with appropriate parameterization, and the evolution results of the independent and coupled scenarios are compared. The simulation data show that in the environment of single university incentive strategy implementation, the ranking of incentive effects is, in order, tax benefits > networking resources > reputational gains.

Authors: Xin Lujuan
Published: December 2023

In this paper, we first extracted the time-domain features, frequency-domain features and spatial-domain features of EEG signals, combined with the three-stage feature selection algorithm applicable to the binary classification problem and the multi-classification problem, and constructed the SEE model for emotion recognition based on EEG signals. Then, based on the three-level design model of emotion, emotion decoding and labeling are carried out on the instinctive layer, behavioral layer and reflective layer of product design, and the constructed model is combined to improve the product design emotionally. Finally, after analyzing the results of product emotion annotation, we explore the performance of the EEG-based emotion recognition model and the improvement effect of product design emotionalization. The results showed that the average accuracy of the EEG signal emotion recognition model for various emotion recognition was about 0.99, and the intensity of emotion intensity in Dahe was 0.32 and 0.25, respectively, accounting for 0.57 of the total sample, and the performance evaluation indicators of the eight emotions were greater than 0.85. Ninety percent of product experiencers had pre- and post-improvement differences between [0.12, 0.22] for happiness and [-0.20, -0.04] for dissatisfaction.

Authors: Li Lin
Published: December 2023

In this paper, the forward neural network multi-feature fusion algorithm is used to extract the emotional features of music culture on artificial intelligence technology, considering the diversity and intermittency of the emotional features of the study, which needs to be parameterized. In the forward neural network architecture, the activation value obtained by using the nonlinear activation function is used, and the results obtained are passed to the next layer of data to realize layer-by-layer forward computation, which leads to the back-propagation activation function. The music culture emotion classification model is constructed based on the propagation mode of the forward neural network to determine the emotion recognition process. The research object is selected, the research process is determined, and in order to ensure the true validity of the research, it is necessary to test the reliability and validity of the research design scheme and to develop an empirical analysis of the comparison between popular music and traditional music culture. The results show that on the model, especially in the recognition of sacred, sad, passionate emotion type of music classification accuracy reached more than 88.2%. This paper’s model can improve the classification accuracy of music emotion to a certain extent. In the ontological knowledge analysis of popular music and traditional music culture, all three editions of textbooks show that general knowledge of music is predominant and has a large proportion, appreciation knowledge and extended knowledge are also considerable, and music knowledge is the least and has a small proportion. This study demonstrates the synergistic development of traditional culture and modern popular music, which is of great significance to the development of music education in colleges and universities.

Authors: Xu Jing
Published: December 2023

In this paper, on the basis of the Unity3D engine, image feature points are coarsely extracted, and a quadtree-based division algorithm is applied to filter the optimal FAST corner points. The fast 3D reconstruction technique is constructed through the construction method of nonlinear scale space similar to scale-invariant feature transform (SIFT), which is layer incremented according to the scale level logarithmic layer. The reconstructed 3D virtual teaching laboratory tool is obtained by importing the matched feature points into the model after the diffusion is completed. Finally, the teaching process and teacher-student behavioral data analysis were conducted for TCM and acupuncture students using the medical aromatherapy experimental course “Clinical Experiment of Aromatherapy for Primary Dysmenorrhea” as the teaching objective. The results showed that the maximum value of iFIAS of the experimental group was 100, and the mean value was 79.35, while the maximum value of technical iFIAS of the control group was only 51.32, and the mean value was 21.34, which was a significant difference between the two. It shows that the teaching method improves classroom learning interest and effect. The purpose of this paper is to provide relevant opinions and references for the future development direction of the combination of aromatherapy teaching and 3D virtual reality.

In this work, the ideology and political characteristics are iteratively calculated using Cuckoo Search Algorithms and the Extreme Learning Machine. The ideology and political objective function are then obtained using CS-ELM. A CS-ELM-based index framework for ideology and political education effect in educational institutions is developed, all of the bird’s nest objective function values are calculated, as well as the bird’s nest position with the highest objective function value is retained in order to accurately and effectively evaluate the current state of ideology and political education effect in educational institutions. The experimental data set is an evaluation of the ideology and political education effects of colleges and universities from 2013 to 2022. Research and analysis are conducted on the evaluation of ideology and political education in institution of higher education in order to remove the quantitative definition of the collected raw data, and mixing is used to process the raw data to make it into a dimensionless one. The hierarchy of higher education has an impact on the establishment of high-quality economies. The CS-ELM model is the best way to assess ideology and political teaching effectiveness in higher education institutions, as per the results. This is because, when looking at the evaluation from an overall perspective, the RMSE value is 0.007, and the R-value is 0.995. This study enhances the quality of instruction in the classroom, promotes a positive environment and attitude, and motivates students to be actively involved in their education.
