The Effect Analysis of the Application of CAI to Japanese Oral Teaching in Colleges
Authors: Tian Xiaofeng
Published: October 2023

In this paper, we first analyze the requirements for teaching spoken Japanese in colleges and universities, design a computer-assisted teaching system using C/S and three-layer hybrid architecture, and create a business flow diagram of the system. The second step is to conduct a technical analysis of the computer-assisted teaching system, and Bayesian theory is employed to model the complex system with multi-factor synergy. The effect of the computer-assisted system on Japanese-speaking teaching courses in colleges and universities was analyzed. The results indicated that the students dictated 4,500 words, while the lowest dictated as little as 300 words, but overall, they were more balanced. The prompt word ratio was directly proportional to the number of repetitions by observing the number of single dictations of students.

Published: October 2023

This paper focuses on the feasible path to enhance the traditional cultural literacy of college students and analyzes the role of teachers’ teaching ability to enhance students’ cultural literacy in college cultural literacy education. Based on the enhancement of college students’ cultural literacy ideologically, morally, behaviorally and psychologically by college cultural literacy education, the primary evaluation indexes of teachers’ teaching ability are set, including basic ability, teaching method, teaching content, teaching attitude and teaching effect. Using the fuzzy C-mean clustering algorithm, we preprocess the teachers’ basic information data, select the evaluation indexes for teachers’ teaching, and complete the clustering optimization. According to the FCM clustering results, teachers’ teaching was classified into three categories, among which the first category T
1 = 0.885, T
3 = 0.923, T
4 = 0.742, indicating that teachers in this category should adjust their working status to achieve the optimal teaching effect and effectively improve students’ cultural literacy.

The purpose of the work is to follow the dynamics of changes in fluorescent signals in the near-surface layers of tissue of injured areas of the back of laboratory animals, which will allow, by indirect evidence, to evaluate the information content of fluorescence diagnosis for subsequent possible diagnostic monitoring of photodynamic therapy of the spinal cord. The model animals were Wistar rats. Two types of contusions were modeled: pneumo-contusion and contusion by a falling load. Methylene blue and indocyanine green were used as photosensitizers. Fluorescence measurements were carried out by imaging and spectrometric methods. A stroboscopic fluorescence imager with an excitation wavelength of 630 nm was used to acquire fluorescence images. The LESA-01-BIOSPEC  spectrometer with a He-Ne laser excitation allowed to obtain spectra. It was shown that both methods make it possible to estimate the fluorescence value of methylene blue and indocyanine green in the tissues under study. Moreover, the photographic method also allows to obtain the spatial distribution of fluorescence. The general trend found in the data is a more intense and uniform fluorescence of the dorsal region of rats with methylene blue and a less intense, but more contrasting distribution of indocyanine green. The presented methods are non-invasive, which makes them attractive for diagnostic use. However, due to the shallow depth of signal reception, the condition of the spine can be determined only indirectly, by the condition of the near-surface layers of tissue that accumulate the photosensitizer.

A gravidez na adolescência é um problema de saúde pública devido aos riscos relacionados à sua ocorrência. Logo, a assistência de enfermagem torna-se essencial para o início precoce e acompanhamento do pré-natal, com intuito de alcançar resultados favoráveis no ciclo gravídico-puerperal. O objetivo deste trabalho foi analisar, na literatura, a assistência de enfermagem no pré-natal e a percepção da gestante adolescente sobre a assistência recebida. Trata-se de uma revisão integrativa da literatura, cujas buscas foram realizadas em junho de 2022, nas bases de dados SCOPUS, Web of Science, LILACS, MEDLINE (PubMed) e BDENF. Foram selecionados 12 artigos para compor a amostra deste estudo. Observou-se que as adolescentes apontaram situações positivas durante a assistência pré-natal, como: relacionamento e tratamento respeitoso, participação em grupos de gestantes adolescentes, abordagens diferenciadas para orientações de educação em saúde, promoção do autocuidado, conscientização sobre importância do pré-natal e inserção familiar. Entretanto também relataram situações negativas, como: deficiências nas orientações, falta de habilidades dos profissionais em se relacionar com adolescentes, preconceito, atitudes de desencorajamento, comprometimento da privacidade e confidencialidade, assim como interrupção na continuidade do cuidado. Os achados desta revisão demonstraram que a assistência de enfermagem em sua maioria é respeitosa e acolhedora, entretanto a percepção das adolescentes grávidas variou entre experiências negativas e positivas, influenciando no seguimento do pré-natal, por isso é necessário aprimoramento dos enfermeiros para atendimento da gestante adolescente.

Authors: Hamanduna Antonius O. Lapu , Widjanarko Putut
Published: October 2023

Freedom of speech is one of the pillars of democracy that is being problematised as new media technologies are increasingly used in people's lives. In Indonesia, this can be seen in the debate over the UU ITE, passed in 2008, one aspect of which regulates the dissemination of information, fake news, and the like in the digital public sphere. For its critics, several articles in the UU ITE threaten freedom of expression and are considered a factor in the democracy regression in Indonesia. Using the DNA method, this research investigates the discourse and actors involved in the debate and how the discourse network is shaped. There are two periods covered, namely October 2016 to December 2016 and February 2021 to June 2021, when the government issued an official explanation or further regulation of the ITE Law. From three prominent online media (Kompas.com, detik.com, and Tirto.id), 359 articles were obtained and then coded based on actors and discourses. Therefore, this research shows the discourse coalition on the issue of freedom of speech. This research shows that the second period of debate involved more actors and discourses and changed the discourse network. There are realignments of network coalition by the state apparatus to be more supportive towards the more democratic discourse, although it is not necessarily materialised in the policymaking decision.

This study aims to observe the implementation of internal communication within the company and how the company implements the work-life balance of its employees. This study utilises the Organisational Control Theory from Phillip Tompkins and George Cheney in Littlejohn and Foss, which is stated in four ways: simple control, technical control, bureaucracy, and conservative control, and uses the concept of work-life balance from Fisher et al., where there are four dimensions of forming a work-life balance: work interference with personal life, personal life interference with work, work enhancement of personal life, and personal life enhancement of work. The results of the study found that employees' work-life balance is obtained unequally by all employees. A hierarchy within the company shows no equal position in the organisation. The managerial position levels and above feel like they have more work-life balance than ordinary employees.
Shopping simulation: BTS army hyper-reality on the Tokopedia marketplace
Authors: Srinarwati Dwi Retnani
Published: October 2023

This paper explores the phenomenon of hyperreality within the context of online shopping and fandom culture, focusing specifically on the vibrant and dedicated fanbase of the popular South Korean boy band BTS, known as the BTS Army. Drawing upon the virtual marketplace of Tokopedia as a case study, we investigate the unique and immersive shopping experiences created by the BTS Army as they engage with merchandise related to their favourite band. Qualitative content analysis with Baudrillard Theory perspectives is used to unravel the complexities of the BTS Army's consumer behaviour, purchasing patterns, and collective interactions within this simulated environment. The findings demonstrate that the Tokopedia marketplace is a hub for the BTS Army, where fans navigate a hyperreal shopping landscape infused with emotional connections, shared meanings, and transformative experiences. Through acquiring and displaying BTS-related merchandise, fans construct and reinforce their identities, cultivate a sense of belonging, and participate in a hyperreal world that blurs the boundaries between fandom and consumer culture. It provides insights for marketers, platform operators, and researchers into the dynamics of hyperreal fandom-driven markets, emphasising the significance of emotional engagement, community building, and immersive experiences for capturing the attention and loyalty of dedicated fan communities.

Optimization of Hybrid Composite Laminates with Distinct Ply Thicknesses Using Integer Programming
Authors: Borwankar Pranav , Zhao Wei , Kapania Rakesh K. , Bansal Manish
Published: October 2023

Optimization of constant-stiffness composite laminates with discrete values of fiber orientations and ply thicknesses is a nonconvex combinatorial problem. Recent studies show that this problem can be efficiently solved using the mixed integer program (MIP) by reformulating lamination parameters as functions of decision variables that represent fiber orientation and thickness choices. These formulations are limited to analyzing laminates having plies of the same thickness and material. This paper extends the previously employed lamination parameter reformulation to enable laminate designs with plies of different thicknesses and materials, thereby leading to MIP with cubic constraints. The linearization techniques are employed to convert cubic constraints of buckling load factors in terms of binary variables into sets of linear constraints that are efficiently solved with optimization algorithms for MIPs. It is shown that the use of distinct ply thicknesses in the optimization further reduces the mass of single-material laminates made with carbon-fiber-reinforced polymer when compared with previous studies using the same material. Additionally, the combination of plies made of glass-fiber-reinforced polymer and carbon-fiber-reinforced polymer with distinct thicknesses is shown to reduce the weight penalty when optimized for cost minimization in comparison to plies with uniform thickness.
Direct Numerical Simulation of Boundary Layers over Microramps: Mach Number Effects
Authors: Della Posta Giacomo , Fratini Marco , Salvadore Francesco , Bernardini Matteo
Published: October 2023

Microvortex generators are passive control devices with heights below the boundary-layer thickness that have been proposed to mitigate the detrimental effects of shock-wave/boundary-layer interaction. Despite their demonstrated control effectiveness, several aspects of the flow induced in turbulent boundary layers still need to be characterized thoroughly. In this work, we present a campaign of direct numerical simulations of a turbulent boundary layer on a microramp, to investigate the effect of the Mach number, from subsonic to supersonic regime. We show that the flow topology changes significantly because of compressibility effects, and that typical wake features do not scale linearly with the geometry dimensions but rather depend on the incoming flow conditions. Moreover, we investigate the spectral content in time and space of the wake, which is dominated by the Kelvin–Helmholtz instability developing along the shear layer. For larger Mach numbers, the shedding onset is postponed and exhibits a lower peak frequency that evolves in space. Finally, we extract the spatially coherent structures convected in the wake by means of a dynamic mode decomposition along the characteristics, which represents effectively and efficiently the evolution of the entire field, despite the convective nature of the flow under consideration.
The Role of Tacit Knowledge in Influencing Leadership on Change Management
Authors: Makhanya Monument T. B. , Vezi-Magigaba Makhosazana Faith
Published: October 2023

This paper explores the positive impacts of tacit knowledge in leadership on change management, focusing on organisational leaders and employees. The significance of tacit knowledge in influencing leadership on change management is critical since tacit information includes significant insights, experience and intuition that leaders possess. Using and exploiting this knowledge helps to improve decision-making, create successful change initiatives, and foster effective leadership during times of uncertainty and transformation. Regarding the influence of tacit knowledge on leadership in change management, there is a sizable knowledge vacuum. Although the value of tacit knowledge in a variety of organisational situations is becoming more well-recognised, little is known about how specifically it affects leadership during change management processes. This paper concludes that tacit knowledge in leadership provides insight into where theoretical models are and are not utilised. A successful change agent will make decisions based on intuition. Tacit knowledge is valuable, and leaders must find methods to use it while also developing systems for capturing and sharing it throughout the organisation, such as through storytelling, communities of practice, or mentorship programmes. This article has eight recommendations for organisations, businesses as well as leaders regarding tacit knowledge handling during the process of change. This article employed secondary sources as methodology, and the collected data were analysed using text content to extract relevant insights.

Pneumonia is a serious chest disease that affects the lungs. This disease has become an important issue that must be taken care of in the field of medicine due to its rapid and intense spread, especially among people who are addicted to smoking. This paper presents an efficient prediction system for detecting pneumonia using nine pre-trained transfer learning models based on deep learning technique (Inception v4, SeNet-154, Xception, PolyNet, ResNet-50, DenseNet-121, DenseNet-169, AlexNet, and SqueezeNet). The dataset in this study consisted of 5856 chest x-rays, which were divided into 5216 for training and 624 for the test. In the training phase, the images were pre-processed by resizing the input images to the same dimensions to reduce complexity and computation. The images are then forwarded to the proposed models (Inception v4, SeNet-154, Xception, PolyNet, ResNet-50, DenseNet-121, DenseNet-169, AlexNet, SqueezeNet) to extract features and classify the images as normal or pneumonia. The results of the proposed models (Inception v4, SeNet-154, Xception, PolyNet, ResNet-50, DenseNet-121 DenseNet-169, AlexNet and SqueezeNet) give accuracies (98.72%, 98.94%, 98.88%, 98.72%, 96.2%, 94.69%, 96.29%, 95.01% and 96.10%) respectively. We found that the SeNet-154 model gave the best result with an accuracy of 98.94% with a validation loss (0.018103). When comparing our results with older studies, it should be noted that the proposed method is superior to other methods.

Coronavirus-specific antibodies can be detected in the blood of people who have recently recovered from coronavirus disease-2019 (COVID-19). Convalescent-Plasma (CP) transfusion process proved that it's among the most efficient protocols, and it's used in hospitals to treat various infections and diseases. Several medical issues have been addressed due to the growing interest in creating Artificial Intelligence (AI) applications. However, considering the virus's enormous potential harm to global public health, such uses are insufficient. This proposed systematic review and meta-analysis aims to obtain an overview of COVID-19, highlight the limits of decision-making approaches, and give healthcare professionals information about the technique's advantages. Between 2016 and 2021, five databases, namely IEEE Xplore, Web of Science, PubMed, Science Direct, and Scopus, were utilized to run four sequences of search queries. As a result, 477 studies are found to be relevant. Only six studies were thoroughly examined and included in this review after screening articles and using proper inclusion criteria, highlighting the lack of research on this crucial topic. Studies' findings were reviewed to identify the gaps in all the evaluated papers. Motivations, problems, constraints, suggestions, and case examples were thoroughly examined. This study seeks to answer how we support the researchers with collected information for managing transfusion of the highest quality CP to the most critical COVID-19 patients across telemedicine hospitals.

Purpose. In the history of the development of Russian fortification architecture in Siberia in the era of Peter I, the most unique situation and bright page should be considered the construction in a short time of a line of 930 miles fortresses along the right bank of the Middle and Upper Irtysh from the Omsk fortress to the Ust-Kamennaya. For Siberia, this was a unique situation, since previously fortified lines had not been created here. Therefore, it is important to study and characterize the natural and geographical conditions of the Russian development of the region.

Results. This study is devoted to resolving a complex of problems related to the history and archaeology of the fortification of the Petrine time along the Middle Irtysh (within the modern Cherlak district of the Omsk region). Here we have passed the water and foot routes. In the course of the work, natural conditions for the placement of defensive objects and their search at the present time, the state and types of communication routs, the presence of scaffolding in the immediate vicinity, stone and ore resources, etc. were considered

Conclusion. In general, the passed route provided significant scientific results, which made it possible to objectively characterize the conditions of the territory development in the Middle Irtysh by Russians in the time of Peter the Great. As a result of the study, we were able to significantly clarify the history of the emergence and reconstruction of the fortification objects: the Solianoi Povorot and Krutoyarka villages. Prospects for further study of these sites are associated with archaeological excavations.
Archaeological Finds of the 18th Century in the Village of Povalikha
Authors: Golovchenko N. N. , Nazarov K. A.
Published: October 2023

Purpose. Russian rural archeology of the Verkhneobskoi Region is a potentially promising area of scientific research, so any materials related to it must be introduced into scientific circulation in a timely manner. However, the number of publications on this topic in the region is still very small. This article presents archaeological finds from the cultural layer of the village of Povalikha, founded in 1719 in the department of the Beloyarskaya fortress (the Altai Region).

Results. Four archaeologically intact vessels were found. Three vessels are unique in their shape and have a recess from the rim to the bottom, the question of their purpose remains controversial. A copper coin of 1739 was found in one of them. A summary of the numismatic complex discovered in the village is given. Individual fragments of ceramic vessels, a birch bark back from shoes and a fishing hook have been studied. The authors discuss a need for a broader study of Russian settlements of the 18th century located in the Altai Region.

Conclusion. The authors conclude that the accidental discovery of representative artifacts indicates the clear prospect of thorough reconnaissance studies in the territory of the village of Povalikha. At the same time, it should be noted that the archaeological study of life support systems and the culture of everyday life of the Russian pioneers in the Verkhneobskoy Region is largely at the stage of initial accumulation of materials.
The Northernness in the Film Documents: “Our Great North” (1925)
Authors: Golovnev I. A.
Published: October 2023

Visual anthropological materials, in particular, documentary films, played a significant role in forming the perception of in the 20th century. In the 1920s in the USSR, the North was one of the main locations of the shooting of ethno-geographic films. Created in the region, they literally became the discovery of this territory for the capitals and the central regions population. Based on the analysis of archival materials, periodicals and newsreel data, the article introduces into scientific circulation information about the film “Our Great North” by L. K Verigo-Dorovsky. The method of analysis of the film was its research interpretation –presentation in the form of a film text. The author demonstrates potential of a film document as a tool for recording and broadcasting the ethno-cultural and economic potential of the region as a multi-layered historical source.

Purpose. The paper presents a description of the stratigraphic and planigraphic situation at the excavation 3 of the Lakhuti IV site (Khovaling loess plateau, Tajikistan) recorded during field work in 2022.

Results. The cross-section has 18 layers grouped into three strata: L6 glacial period sediments (MIS 14), 6a and 6b soil complexes (MIS 15). The identified technocomplexes belong to the late Karatau culture of the Lower Paleolithic of Tajikistan. The level 5.2 planigraphy indicates that the investigated area could be a fragment of a workshop site where primary processing of stone raw materials was carried out. The layer L6 artefacts indicates that the region was continuously developed by humans, and glacial conditions in the Middle Pleistocene affected the intensity of these processes only.

Conclusions. The closest analogues to the late Karatau complexes can be traced in the Soan pebble-flake industries of the Northern Hindustan. They have a similar age to Tajik materials (second half of the Middle Pleistocene), geomorphological position (deposits of high terraces in the upper reaches of the Indus, Soan, and other rivers in the Himalayas foothill zone), a similar raw material base (river alluvium). Also they have a number of technical and typological characteristics, which include: citron and radial knapping; a higher percentage of large flakes and “citrons”; choppers, simple side-scrapers and unifaces in tool-kits; lack of bifacial technique. As a result of a new stage in the study of the Lower Paleolithic complexes in the region, authors proposed a new model, according to which the region was continuously developed by hominins, and glacial conditions mainly influenced the intensity of these processes.
Non-Ceramic Site of Shamanka 8 on the Southern Coast of Baikal Lake

Published: October 2023

Purpose. The southern coast of lake Baikal is a territory known in Siberian archaeology for its Kitoi cemeteries. Besides burials of the Shaman capes there are some Neolithic and Bronze age complexes at Circum–Baikal railway. In 2012 it the first non-ceramic site was discovered in South Baikal, which was named Shamanka 8. This paper presents the assemblage of this complex and discusses its chronological and cultural features.

Results. The Shamanka 8 site is located on the top of the third hill of the Shaman cape. The cultural layer lies under the Holocene Optimum sediments. The site stratigraphic structure is characterized by compression. There is no bone fragments and ceramic. For lithic knapping, mainly local raw material (quartz) were used. The quartz assemblage has such features as poor formal standardization, high degree of flake fragmentation, cores with the orientation of fracture plane relative to the longitudinal axis, bipolar reduction. All of these specifics are explained by uneven fracture characteristics and bad workability of quartz, as well as its breakage patterns. Some artifacts, including single non-quartz tool, suggest that there may be a connection between the Shamanka 8 site and the industries of the Final Paleolithic sites in the Northern Baikal region and the Irkutsk region. Quartz small knife (?), carinated end-scraper and tubular core have analogies in the 2nd cultural layer of the Kurla II site, dated by 13.5 uncal kya. Similarly dated quartz components of Nirikan I and flint tool-kit of Verkholenskaya Gora I include other cultural link types.

Conclusion. The similarity in the morphology of some tools with Final Paleolithic counterparts and stratigraphic position of finds allow us to assume the Final Sartan age of the Shamanka 8 site and dates it to the Bølling – Allerød warming. However, in the absence of direct radiocarbon dating, an Early Holocene/Early Neolithic attribution of the site is also possible. Further studies may help resolve this issue.
