Local Path Planning for Mobile Robots Based on Fuzzy Dynamic Window Algorithm
Authors: Sun Ying , Wang Wenlu , Xu Manman , Huang Li , Shi Kangjing , Zou Chunlong , Chen Baojia
Published: October 2023

Due to the increased employment of robots in modern society, path planning methods based on human–robot collaborative mobile robots have been the subject of research in both academia and industry. The dynamic window approach used in the research of the robot local path planning problem involves a mixture of fixed weight coefficients, which makes it hard to deal with the changing dynamic environment and the issue of the sub-optimal global planning paths that arise after local obstacle avoidance. By dynamically modifying the combination of weight coefficients, we propose, in this research, the use of fuzzy control logic to optimize the evaluation function’s sub-functions and enhance the algorithm’s performance through the safe and dynamic avoidance of obstacles. The global path is introduced to enhance the dynamic window technique’s ability to plan globally, and important points on the global path are selected as key sub-target sites for the local motion planning phase of the dynamic window technique. The motion position changes after local obstacle avoidance to keep the mobile robot on the intended global path. According to the simulation results, the enhanced dynamic window algorithm cuts planning time and path length by 16% and 5%, respectively, while maintaining good obstacle avoidance and considering a better global path in the face of various dynamic environments. It is difficult to achieve a local optimum using this algorithm.

Authors: Shi Weize , Wang Yabin
Published: October 2023

Due to the characteristics of peroxide explosives, which are difficult to detect via conventional detection methods and have high explosive power, a fluorescent photoelectric detection system based on fluorescence detection technology was designed in this study to achieve the high-sensitivity detection of trace peroxide explosives in practical applications. Through actual measurement experiments and numerical simulation methods, the derivative dynamic time warping (DDTW) algorithm and the Spearman correlation coefficient were used to calculate the DDTW–Spearman distance to achieve time series correlation measurements. The detection sensitivity of triacetone triperoxide (TATP) and H2O2 was studied, and the detection of organic substances of acetone, acetylene, ethanol, ethyl acetate, and petroleum ether was carried out. The stability and specific detection ability of the fluorescent photoelectric detection system were determined. The research results showed that the fluorescence photoelectric detection system can effectively identify the detection data of TATP, H2O2, acetone, acetonitrile, ethanol, ethyl acetate, and petroleum ether. The detection limit of 0.01 mg/mL of TATP and 0.0046 mg/mL of H2O2 was less than 10 ppb. The time series similarity measurement method improves the analytical capabilities of fluorescence photoelectric detection technology.
Learning-Based Seismic Velocity Inversion with Synthetic and Field Data
Authors: Farris Stuart , Clapp Robert , Araya-Polo Mauricio
Published: October 2023

Building accurate acoustic subsurface velocity models is essential for successful industrial exploration projects. Traditional inversion methods from field-recorded seismograms struggle in regions with complex geology. While deep learning (DL) presents a promising alternative, its robustness using field data in these complicated regions has not been sufficiently explored. In this study, we present a thorough analysis of DL’s capability to harness labeled seismograms, whether field-recorded or synthetically generated, for accurate velocity model recovery in a challenging region of the Gulf of Mexico. Our evaluation centers on the impact of training data selection and data augmentation techniques on the DL model’s ability to recover velocity profiles. Models trained on field data produced superior results to data obtained using quantitative metrics like Mean Squared Error (MSE), Structural Similarity Index Measure (SSIM), and R2 (R-squared). They also yielded more geologically plausible predictions and sharper geophysical migration images. Conversely, models trained on synthetic data, while less precise, highlighted the potential utility of synthetic training data, especially when labeled field data are scarce. Our work shows that the efficacy of synthetic data-driven models largely depends on bridging the domain gap between training and test data through the use of advanced wave equation solvers and geologic priors. Our results underscore DL’s potential to advance velocity model-building workflows in industrial settings using previously labeled field-recorded seismograms. They also highlight the indispensable role of earth scientists’ domain expertise in curating synthetic data when field data are lacking.
Is Entrepreneurship the Key to Achieving Environmental Sustainability? A Data-Driven Analysis from the Asia-Pacific Region
Authors: Le Thai-Ha , Nguyen Canh Phuc , Bui Manh-Tien
Published: October 2023

This study examines the relationship between entrepreneurship density and environmental quality in 28 Asia-Pacific countries using the PMG estimator as a panel data estimation method in the context of the ARDL model. The study finds that entrepreneurship density has no statistically significant short-term effects on CO2 emissions in all three economic sectors, but it appears to have statistically significant effects on CO2 emissions in agriculture and industry in the long run. The study suggests that the nature of entrepreneurship activities and their impact on the environment changes from low-income to high-income countries, with entrepreneurship activities with innovations and creativity primarily found in the industrial sector, improving economic efficiency and reducing industrial emissions. However, entrepreneurship activities with natural resource rents, such as large land use or forest rents, can cause environmental degradation. The study provides further insights by interacting entrepreneurship density with the income variable, revealing that entrepreneurship density has different effects on sectoral emissions in low, lower-middle, upper-middle, and high-income countries. Finally, the study provides interesting findings on the relationship between entrepreneurship density and environmental quality, such as biodiversity and water quality.
On Symmetric Additive Mappings and Their Applications
Authors: Ali Shakir , Alsuraiheed Turki , Varshney Vaishali , Wijayanti Indah Emilia
Published: October 2023

The key motive of this paper is to study symmetric additive mappings and discuss their applications. The study of these symmetric mappings makes it possible to characterize symmetric n-derivations and describe the structure of the quotient ring S/P, where S is any ring and P is a prime ideal of S. The symmetricity of additive mappings allows us to transfer ring theory results to functional analyses, particularly to C∗-algebras. Precisely, we describe the structures of C∗-algebras via symmetric additive mappings.
Lambert W Random Variables and Their Applications in Loss Modelling
Authors: Käärik Meelis , Selart Anne , Puhkim Tuuli , Tee Liivika
Published: October 2023

Several distributions and families of distributions are proposed to model skewed data, e.g., with skew-normal and related distributions. Lambert W random variables offer an alternative approach in which, instead of constructing a new distribution, a certain transformation is proposed. Such an approach allows the construction of a Lambert W skewed version from any distribution. Here, we choose the Lambert W normal distribution as a natural starting point and include the Lambert W exponential distribution due to the simplicity and shape of the exponential distribution, which, after skewing, may produce a reasonably heavy tail for loss models. In the theoretical part, we focus on the mathematical properties of obtained distributions, including the range of skewness. In the practical part, the suitability of the corresponding Lambert W transformed distributions is evaluated on real insurance data. Finally, the results are compared with those obtained using common loss distributions.
A Novel Four-Dimensional Memristive Hyperchaotic Map Based on a Three-Dimensional Parabolic Chaotic Map with a Discrete Memristor

Published: October 2023

Recently, the application of memristors in chaotic systems has been extensively studied. Unfortunately, there is limited literature on the introduction of discrete memristors into chaotic maps, especially into non-classical multidimensional maps. For this reason, this paper establishes a new three-dimensional parabolic chaotic map model; in order to improve the complexity and randomness of the map, it is coupled with a square-charge-controlled discrete memristor to design a new four-dimensional memristive hyperchaotic map. Firstly, the stability of the two maps is discussed. And their dynamical properties are compared using Lyapunov exponential spectra and bifurcation diagrams. Then, the phase diagram and iteration sequence of the 4D memristive hyperchaotic map are obtained. Meanwhile, we investigate the hyperchaotic states, the transient chaos, state transfer and attractor coexistence phenomena of the four-dimensional memristive map. In particular, the special state transfer phenomenon of switching from a periodic attractor to a quasi-periodic attractor and the special coexistence phenomenon of a quasi-periodic attractor coexisting with a quasi-periodic attractor around fixed points are found, which have not been observed in other systems. Finally, the phase-track diagrams and iterative sequence diagrams of the four-dimensional memristive map are verified on a digital experimental platform, revealing its potential for practical applications.

Leptospirosis is a zoonotic disease that poses a significant threat to human and animal health worldwide. Among different animal species, pigs are known to play a crucial role in the transmission of the pathogenic Leptospira spp. This study aimed to investigate the prevalence of Leptospira spp. infection and associated risk factors in backyard pigs in the state of Paraná, Brazil. A set of 1393 blood samples were collected from pigs on 188 subsistence properties from 136 different municipalities of the Paraná state and tested using the microscopic agglutination test (MAT) to detect antibodies against 24 different Leptospira spp. serovars. The results revealed an overall seroprevalence of 15.87% (221/1393; 95% CI: 13.95–17.78%) for Leptospira spp. antibodies, with Icterohaemorrhagiae, Butembo, and Pomona being the most commonly detected in serovar levels. The lack of rodent control (OR 1.12, 95% CI: 0.63–1.98, p = 0.02) was the only variable associated with disease incidence and was identified as a significant risk factor for Leptospira spp. infection in this context. These findings highlight the urgent need to implement effective control measures, such as improved housing conditions, rodent control, and veterinary assistance, to prevent the spread of this zoonotic disease in backyard pigs in Paraná, Brazil.

Published: October 2023

The small-molecule antiviral drug ensitrelvir targets the 3C-like protease of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study evaluated its inhibitory effect on viral replication in a delayed-treatment mouse model and investigated the relationship between pharmacokinetic (PK) parameters and pharmacodynamic (PD) effects. SARS-CoV-2 gamma-strain-infected BALB/c mice were orally treated with various doses of ensitrelvir starting 24 h post-infection. Effectiveness was determined 48 h after first administration based on lung viral titers. Ensitrelvir PK parameters were estimated from previously reported plasma concentration data and PK/PD analyses were performed. Ensitrelvir doses ≥ 16 mg/kg once daily, ≥8 mg/kg twice daily, or ≥8 mg/kg thrice daily for two days significantly reduced lung viral titers compared to that of the vehicle. PK/PD analyses revealed that mean AUC0–48h post-first administration, plasma concentration 48 h post-first administration (C48h), and total time above the target plasma concentration (TimeHigh) were PK parameters predictive of viral titer reduction. In conclusion, ensitrelvir dose-dependently reduced lung SARS-CoV-2 titers in mice, suggesting it inhibited viral replication. PK parameters C48h and TimeHigh were associated with sustained ensitrelvir plasma concentrations and correlated with the reduced viral titers. The findings suggest that maintaining ensitrelvir plasma concentration is effective for exerting antiviral activity against SARS-CoV-2.

Published: October 2023

Gammarus plays a central role in the detritus cycle and constitutes an important component in food webs. At the same time, taxonomy and morphological identification to species level is highly challenging in this genus. Thus, the freshwater gammarid diversity in the Caucasus biodiversity hotspot remains largely unstudied to date. We use DNA barcoding for the first time in assessing the biodiversity and taxonomy of gammarids within the amphipod genus Gammarus in the limnic ecosystems of Armenia. The results expand the knowledge on possible diversity and evolutionary lineages of Gammarus in the region. DNA barcodes obtained from our Armenian specimens consistently indicate four to six well-defined molecular operational taxonomic units (MOTUs) within three distinct morphospecies clusters. One to three MOTUs correspond to the Gammarus balcanicus species complex, two MOTUs to the G. komareki complex, and one MOTU to the G. lacustris complex. Five BINs out of six were unique and new to BOLD.
Valorizing the Input and Output Waste Streams from Three PtX Case Studies in Denmark—Adopting a Symbiotic Approach
Authors: Lybæk Rikke , Kjær Tyge
Published: October 2023

This study aimed to investigate the waste streams from the production of hydrogen energy carriers from PtX technology and identify how they can be valorized by applying a symbiotic approach to enable greater utilization of the inputs and outputs from such plants. Various electrolysis development projects are under development or in the pipeline in Europe and Denmark, but in many cases, it is not clear how waste streams are emphasized and valued in these projects. Thus, three exploratory case studies (a city, a rural, and an energy hub case) were investigated herein exemplifying state-of-the-art electrolysis projects currently being deployed, with a focus on identifying how and to what extent waste streams are being valorized in these projects and energy system integration is being pursued. Inspired by the industrial symbiosis literature, we analyzed how internal, regional, and long-distance symbiotic collaboration is realized within these cases and found them to be very different in terms of the energy carrier produced, the current development stage, and the access to appropriate energy infrastructure. This paper concludes that the co-location of PtX technology near biogas plants would provide a great opportunity for the integration of the produced energy carriers and waste streams into the existing energy system and, hence, could assist in stabilizing fluctuating renewable energy sources to enable their more efficient use in the energy system.

Tuberculosis (TB) results from infection with members of the Mycobacterium tuberculosis complex (MTBC) and represents a major global public health concern. We here sought to assess the perceptions of human and animal TB and the prevalence of circulating MTBCs lineages and associated risk factors through a cross-sectional survey of 335 individuals presenting with symptoms of pulmonary or extrapulmonary TB in the Manyara region of Tanzania. After the enrollment of participants, a questionnaire survey was conducted, samples were collected for bacterial culture, and real-time multiplex PCR was performed to differentiate amongst primary animal and human MTBC lineages. The results show poor TB awareness: 31.6% of the participants were not aware of human TB; 82.4% were unaware of animal TB and 95.2% lacked awareness of zoonotic TB (zTB) transmission. A total of 18 recovered specimens (5%; 95% CI: 3–8%) were positive by culture, all of which were typed as M. tuberculosis sensu stricto using a lineage-specific PCR assay. While no single risk factor was significantly associated with MTBC culture positivity, the survey revealed considerable self-reported high-risk practices for contracting zTB. Together, the results show that Manyara residents have poor knowledge of diseases caused by MTBCs and high evidence of risky practices for contracting zTB.

Published: October 2023

In the course of the study, in order to detect the implementation of safe cargo operations during the operation of «vertical» cargo blocks, it was proposed to choose a contact network within the cargo front. To receive the reception of a train driven by an electric locomotive, with a partial refusal from the contact network, three competitive options are proposed that teach the possibility of reception. As part of the variation study, when receiving a train, coasting is detected, in coastdown mode. The substantiation of the proposed acceptance technology is supported by the development of the catch-up technology, modeling the possibility and probability of receiving a train on the cut (graphical integration of the train motion equation), as well as the development of technical and technological stability to ensure the implementation of the proposed circuit-technological solution.

Communication is carried out directly (communication during classroom classes, in the framework of writing term papers and qualification papers; in the preparation of various events, etc.) and indirectly (providing access to educational and information materials on the University's web resources; access to the library repository; creating groups in social networks, etc.). This structure of communication between the participants of the educational process allows for the implementation of educational and informational (exchange of educational, scientific, educational and methodological information; transfer of socially significant norms and values), organizational (coordination of joint actions, feedback between the subjects of interaction), advisory (clarification of certain issues arising within the educational process) and social (providing support, motivating students) functions.
MODERN ASPECTS OF THE IMPLEMENTATION OF THE COURSE "METEOROLOGY AND CLIMATOLOGY" IN THE EDUCATIONAL PROCESS OF STUDENTS IN THE DIRECTION OF PREPARATION 101 ECOLOGY
Authors: DIACHENKO-BOHUN M. , TIMOSHENKO O.
Published: October 2023

Modern meteorology is a very practical science necessary for social life. Most meteorologists model weather and climate forecasts, while others work for government and military organizations as well as private companies, providing forecasts for aviation, navigation, agriculture, construction, and radio and television broadcasting. In many countries, meteorology is often called "atmospheric physics", and ordinary meteorologists deal more with complex mathematical formulas and calculations that model physical and physico-chemical processes in the Earth's atmosphere. However, since the latter is closely related to all other envelopes, the work of meteorologists also has a distinct geographic element, since only geography needs to be taken into account for weather forecasting and modeling of atmospheric processes. In addition, the conditions of the atmosphere and the processes that take place in it differ in different parts of the globe due to geographic patterns (regions, altitude bands, etc.). Long-term weather conditions in a certain area are called climate. So, climatology is a science that studies such issues as climate formation, description and classification of the global climate, and the impact of human activity on the climate. By its nature, it is more closely related to other geographical disciplines.

Modern research in the field of meteorology and climatology is at the center of mass media reports, as it sheds light on the future of our planet and life on it in light of actual and potential climate change. This is their mission today. they can only answer questions posed as elements of the system of geographic science.

The article contains basic provisions on the environment, aspects of life in various regions, especially natural areas and objects subject to special protection. The work on environmental impact assessment is characterized. The article covers some issues of human bioclimatology, synrheological effects of individual meteorological variables and atmospheric factors and methods of assessing the complex impact of weather on the human body. The influence of climate warming on the health of the population and adaptation to climate change in Ukraine are mentioned.
FORMATION OF THE LEGAL COMPETENCE OF THE FUTURE MASTER OF MANAGEMENT IN THE CONTEXT OF HIS CONFLICT COMPETENCE
Authors: ZHDANOVA-NEDІLKO O.
Published: October 2023

The article presents arguments regarding the relationship between the conflict-related competence and the legal competence of the future manager and the consideration of this circumstance during his professional training in the master's degree. The professionalism of the future manager, whose requirements are considered the specified task, is positioned as a complex and extensive phenomenon, which in its formation is not reduced to the acquisition by the student of education of a static list of personal and professional characteristics and is constantly adjusted by those changes that occur in the professional environment. The availability and constant updating of the experience of responding to conflicts, the flexibility and adequacy of responding to them are considered as one of the important conditions of managerial activity. Accordingly, the need for future managers to gain experience in operational identification of conflict situations and forecasting their development, determination of the consequences of management decisions that may be constructive or destructive, and the ability to act purposefully on the basis of moral, ethical and legal norms is substantiated.

The author suggests that the following should be included among the main principles of the formation of the conflict-related competence of the future manager: the principle of scientificity (the validity of the management's interpretation of the conflict situation by scientific provisions); logicality (rejection of excessive hypotheticality in interpretations in favor of the most logical explanation of existing and predictable events); objectivity (overcoming emotions caused by subjective experience, identifying oneself with conflict participants, and abstracting from personal qualities of opponents to their conflict positions); constructiveness (choice of conflict management strategy and tactics, oriented towards its constructive development from most perspectives); morality (compliance of management decisions with moral and ethical standards); legality (preventing decisions that contradict the legal principles of management and the rights of an employee, citizen, person).

Published: October 2023

The article focuses on some new approaches to teaching Practical Phonetics of English for the students majoring in Philology on the university level. The formation of phonetic skills is an indispensable condition for adequate understanding of a language message, accuracy of expression of thought and performance of a communicative function in language. It is stated that the goal of teaching phonetic material means forming comprehension, pronunciation, rhythmic, and intonation skills.

One of the commonly applied algorithms of forming and improving students’ articulation skills is discussed but the authors focus on one of the stages of it and offer an example of using tongue twisters for practicing pronunciation of sounds. The research shows how to move from purely receptive exercises to receptive and reproductive ones, in which two goals are combined – the formation of listening and speaking skills.

Experience has shown that the application of this strategy deepens the knowledge of basic rules of pronunciation, helps to master the articulation of those sounds that are not typical for the student’s mother tongue, as well as increases the motivation of students to study English in general and makes them sound more natural while speaking English.

SCIENTIFIC-THEORETICAL ESSENCE OF COMMUNICATIVE COMPETENCES OF FUTURE NURSES
Authors: OSTAPENKO Y.
Published: October 2023

Тhe formation of a nurse's communicative competence contributes to her effective professional activity. Lack of communication skills leads to rapid burnout of the medical worker. We often observe that mental, emotional and physical stress leads to the fact that nurses quickly leave the profession.

The duties of a nurse include not only cooperation with the patients and colleagues but also communication and training of the patients' relatives in the elements of care. In addition, a nurse should be able to convince, prove, argue, avoiding direct conflicts but in case of their occurrence she should be able to solve them  positivle. Therefore, it is necessary to pay considerable attention to the formation of communicative competence of future nurses during their studies at professional colleges.

The competence approach is characterized in the article. The content of the consepts of "competence" and "competency" is analysed in it and also the issue of communicative competence and its place in the training of specialists during professional training is considered. The importance of forming communicative competence of future nurses is emphasized. The role of verbal and non-verbal communication and their means as types of professional communication are also defined in the article. In addition, the stages of the nursing process are considered and the need to use communication skills at each stage of the nursing process is shown.
PREVENTION OF PROFESSIONAL DEFORMATIONS OF THE PERSONALITY IN WORK WITH STUDENT YOUTH
Authors: PAVLOV J.
Published: October 2023

A manifestation of the negative influence of the profession on the individual is the appearance of various professional deformations or specific conditions, such as, for example, the phenomenon of mental burnout. Professional deformation means any change caused by the profession that occurs in the body and acquires a permanent character. From this point of view, deformation extends to all aspects of a person's physical and mental organization, which change under the influence of the profession. Traditionally, the understanding of professional deformation is associated with the negative impact of the profession on the psychological characteristics of a person, which complicates his behavior in everyday life and, ultimately, can reduce work efficiency.

Thus, analyzing the above, we can come to the conclusion: the mechanism of the occurrence of professional deformation has quite complex dynamics and is associated with the consolidation of negative changes in professional activity and in everyday behavior and communication. First, temporary negative mental states appear, then positive qualities begin to disappear. Later, in the place of positive properties, negative mental qualities appear, which change the employee's personal profile. There is a permanent distortion of the configuration of the employee's personal profile, which is a deformation. Professional deformations violate the integrity of the individual; reduce its adaptability, stability; negatively affect professional health and work productivity. All this should be taken into account when working with student youth in order to prevent mental burnout in professional activities.

In the article, the authors reveal the methods of expanding the formation of the scientific ecological worldview of student youth in the "Ecology" field of study. The modern educational process requires not only the assimilation of scientific knowledge, but also the education of a moral, ethical, responsible personality in relation to nature, the biosphere, any form of life, as the most important human value.

Life is the most unique and highest value on the planet. Preserving life in all forms and manifestations is the main goal of a modern ecologist today. Creating an artificial environment for his habitat, man, in pursuit of economic profit, began to treat the biosphere in a consumerist way, destroying, destroying, bringing it to a tense state. This attitude towards nature leads not only to the destruction of ecosystems and the biosphere, but also to the impoverishment of the spiritual and moral foundations of a person's personality. In the conditions of the growing ecological crisis, it is necessary to change the attitude towards nature, to understand the value of any form of life. It is nature that can inspire and develop the spiritual and moral basis of a person. In this aspect, environmental education, aimed at changing and improving the scientific outlook, acquires special significance. Only on the basis of a new type of relationship between man and nature is a way out of this crisis possible. In the system of environmental education, new relevant environmental areas and training profiles are emerging. There are new tasks for students.Employers increasingly set high demands for future ecologists: they demand a high level of professional knowledge, skills and abilities, clearly navigate the problems of ecosystem disturbances, apply the latest methods of restoration, quickly and correctly make decisions in situations of a natural and man-made nature, the ability to own innovative technologies.

In connection with the new requirements for a modern ecologist, there is a need to expand the educational process and innovative pedagogical approaches, to expand the scientific outlook of higher education students.

(2018–2022)*
Authors: RYU Jaehan , PARK Jinryung , SEO Minjeong
Published: October 2023

This scoping review examines the “System for Decisions to Forgo Life-Sustaining
Treatment” in Korea from 2018 to 2022 and is based on an analysis of 285
research studies, published in either domestic or international journals. Of the
articles examined, 164 (57.5%) focused on issues related to health science,
while 121 (42.5%) addressed ethical and legal aspects of the system. Articles in
the former category of health science focused on advance care plans,
contemplation on death, decision-making, end-of-life care, biomedical ethics,
and psychosocial factors. Articles in the latter category of the ethical and
legal aspects of the system focused on legal challenges, the right to
self-determination, death with dignity, surrogate decision-making, contemplation
of death, biomedical ethics, and legal frameworks. To ensure the system’s stable
integration into society during this transitional period, it is crucial to
continuously assess its operation in clinical settings. Efforts to establish a
societal consensus on dignified end-of-life experiences and to conduct future
multidisciplinary research should persist.

Authors: SHON Yuha , JEON Heejung , KIM Sanghee
Published: October 2023

Professionalism, which encompasses competencies, ethics, and societal
expectations, is an essential feature of modern medical practice. For nurses,
practical education in clinical settings, including the operating room, can
foster professionalism by demonstrating the importance of patient safety,
ethics, and collaboration. This article reports on a study that investigated
nursing students’ learning journey and perceptions of professionalism during an
operating room practicum. This qualitative descriptive study, which used
Bengtsson (content analysis, analyzed 202 self-reflective reports written by
junior students at a nursing college in one city in South Korea between 2021 and
2022. The analysis yielded 50 key meanings and 10 sub-categories and identified
the following three categories: “Perceptions of a collaborative operating room
care environment,” “Observations on nurses as advocates for surgical patients,”
and “Challenges to professionalism and growth as future perioperative nurses.”
The results of the study indicate that the operating room practicum offered more
than clinical exposure; it also fostered professional growth and shaped ethical
values. On the basis of these findings we suggest that practical education in
the operating should be integrated with ethics education to enhance skills,
cultivate professional awareness, and promote professionalism in nursing.

Published: October 2023

The merdeka program implemented in some schools has clearly encountered many obstacles. One of them is creating and developing teaching modules. The creation of teaching modules must be consistent with 21st century learning so that teaching modules must be based on higher order thinking skills (HOTS). This is no exception at SMP Negeri 3 Wonogiri. Teachers' understanding of HOTS is reflected in a rubric that includes why and how questions. In fact, to build and strengthen the way of thinking and understanding of HOTS, it must be comprehensive, from learning goals to learning assessment. The purpose of the training proposed by the team to be provided to the teachers of SMP Negeri 3 Wonogiri is to support them so that they can successfully create teaching modules based on HOTS. This service cooperates with SMP 3 Wonogiri and the activation teachers of SMP 4 Pracimantoro. The number participating in the training is 27 teachers from many different subjects. The three-day activity begins with training and ends with a speaker presenting classroom teaching examples.
