Authors: Nafiisa Muflihani Dhiiya , Budiarti Any , Marlia
Published: July 2023

Language plays an important role in social communication between speakers and listeners. Through language, opinions, thoughts, and ideas can be easily expressed and understood by others. In communicative interactions, speech acts play a crucial role as they involve actions within the communication. However, speakers and listeners often face difficulties in understanding the context of a conversation. One important aspect of speech acts is the illocutionary meaning contained within them. Speech acts can occur in various everyday life situations, both in oral and written forms. A script of a drama is an example of a written form of speech acts, where utterances serve as the main foundation of a conversation. This research employs a descriptive qualitative research method to examine illocutionary speech acts in the context of written language, focusing on the use of language in Arifin C. Noer's drama script titled "A-A, I-I, U-U." The analysis results indicate the presence of 187 utterances containing illocutionary speech acts, with the dominance of assertive illocutionary acts comprising 90 data (48.13%), followed by directive acts (39.03%), expressive acts (8.56%), and commissive acts (4.28%). No declarative illocutionary acts were found in the script.

Published: July 2023

Objective: This study was designed to compare the effects of hamstring muscle injection of botulinum toxin type A (BoNT/A) combined with periarticular injection to those of simple periarticular injection alone, in terms of early pain reduction and functional recovery following total knee arthroplasty (TKA).

Methods: This study included 40 patients who underwent elective unilateral TKA at our hospital from February 2021 to December 2021. The patients were randomly assigned to either the experimental group (BoNT/A injection into the hamstring muscle + periarticular injection, n = 20 cases) or the control group (0.9% normal saline injection into the hamstring muscle + periarticular injection, n = 20 cases). The preoperative and postoperative 3-day HSS scores were compared between the two groups. Postoperative visual analog scale (VAS) pain scores were observed and compared between the two groups. The Lovett grading method was used to evaluate the postoperative muscle strength of both groups. Additionally, postoperative knee joint pain scores, maximum active flexion angle, and any postoperative adverse reactions were observed and compared between the two groups.

Results: The experimental group showed significantly lower VAS pain scores than the control group at 24 h, 48 h, and 72 h after the operation, with a statistically significant difference (P < 0.05). Furthermore, compared to the control group, the patients in the experimental group exhibited larger knee joint active flexion angles at 1 day, 3 days, and 5 days post-operation, also demonstrating a statistically significant difference (P < 0.05). These findings hold scientific significance (P < 0.05). Additionally, the combined administration of BoNT/A hamstring muscle injection with periarticular injection exhibited a low incidence of adverse reactions during the perioperative period and had no significant effect on quadriceps muscle strength.

Conclusion: The combination of BoNT/A hamstring muscle injection with periarticular injection effectively alleviates early postoperative pain following TKA and promotes early functional recovery of the knee joint.

Published: July 2023

In this paper, the performances of a wavelength interrogation-based optical fiber surface plasmon resonance sensor for hemoglobin (Hb) concentration is investigated by theoretical simulation. The proposed configuration incorporates optical fiber, 70 nm silver, 18 nm barium titanate (BaTiO3), and 2 nm zinc oxide. Simulation results show the sensor exhibits refractive index sensitivity of 4023 nm/RIU and concentration sensitivity of 10.0873 nm/(g·dL), along with Hb concentration varying from 0 to 14 g/dL. This paper especially focuses on the influence of BaTiO3 on the performances of the proposed sensor with light wavelength ranging from 350 to 1000 nm. Comparison analysis indicates sandwiching 18 nm BaTiO3 between sensing layers not only enhances the concentration sensitivity by 30.14% but also decreases the nonlinear error of the sensor from 0.68% to 0.63%. For a wavelength accuracy of 0.1 nm, the proposed sensor can provide a resolution of 0.0099 g/dL for Hb concentration detection.
Transverse energy propagation and interference of elliptical Gaussian beams
Authors: Jin Li  , Shuang-Cheng Tan
Published: July 2023

Elliptical Gaussian beam (EGB) has many different physical properties from circular Gaussian beam. In this paper, the transverse energy flux and intensity of one and two coherent EGBs are studied. In our simulation, the transverse energy flux and intensity varying with waist ratio are discussed in detail. It has been found that through increasing the waist ratio, the transverse energy flux after interference would be strengthened significantly. Although the transverse energy flux is much weaker than the longitudinal energy flux, its signal to noise ratio has been verified to be strong enough for detection. Our derivations are still reasonable for another simulation with general experimental parameters. The simulation results are considered to be helpful for some physical experiments using the transverse energy flux of Gaussian beam, such as an important application in electromagnetic response produced by interaction of high-frequency gravitational waves.
Robust dual color images watermarking scheme with hyperchaotic encryption based on quaternion DFrAT and genetic algorithm
Authors: Hui-Xin Luo  , Li-Hua Gong  , Su-Hua Chen
Published: July 2023

A robust dual color images watermarking algorithm is designed based on quaternion discrete fractional angular transform (QDFrAT) and genetic algorithm. To guarantee the watermark security, the original color watermark image is encrypted with a 4D hyperchaotic system. A pure quaternion matrix is acquired by performing the discrete wavelet transform (DWT), the block division and the discrete cosine transform on the original color cover image. The quaternion matrix is operated by the QDFrAT to improve the robustness and the security of the watermarking scheme with the optimal transform angle and the fractional order. Then the singular value matrix is obtained by the quaternion singular value decomposition (QSVD) to further enhance the scheme’s stability. The encryption watermark is also processed by DWT and QSVD. Afterward, the singular value matrix of the encryption watermark is embedded into the singular value matrix of the host image by the optimal scaling factor. Moreover, the values to balance imperceptibility and robustness are optimized with a genetic algorithm. It is shown that the proposed color image watermarking scheme performs well in imperceptibility, security, robustness and embedding capacity.
Identification of advanced optical modulation formatand estimation of signal-to-noise-ratio based on parallel-twin convolutional neural network
Authors: Xiaowei Dong  , Zhihui Yu
Published: July 2023

In this paper, we design a parallel-twin convolutional neural network (PT-CNN) deep learning model and use the signal constellation diagram to realize the identification of six advanced optical modulation formats (QPSK, 4QAM, 8PSK, 8QAM, 16PSK, 16QAM) and signal-to-noise-ratio (SNR) estimation. The influence of PT-CNN with different layers and kernel sizes is investigated and the optimal network model is chosen. Simulation results demonstrate that the proposed method has the advantages of not requiring manual feature extraction, having the ability to clearly distinguish the six modulation formats with 100% accuracy when SNR of the received signal sequences is higher than 12 dB. In addition, the high-accurate SNR estimation is realized simultaneously without increasing additional system complexity.

Published: July 2023

The rapid development of digital products brings security issues. Digital watermarking technology is an important means to handle these problems. To enhance the imperceptibility of watermark and locate the possible tampering as well, a digital watermarking scheme based on curvelet transform is presented by combining with multiple chaotic maps. The host image is decomposed into three parts, i.e., coarse layer, detail layer and fine layer, with curvelet transform, and a robust watermark is embedded into the coarse layer for copyright protection of digital products. In addition, an authentication watermark is embedded into the fine layer to detect and locate the illegal changes. Simulation results show that the proposed digital watermarking scheme possesses acceptable robustness and security.

Authors: Xianyang Yang  , Wenyu Fu
Published: July 2023

We study a new class of partially coherent array beams with a non-uniform polarization, named radially polarized Gaussian Schell-model array (RPGSMA) beams and analyze the reliability conditions for the array beams based on the unified theory of coherence and polarization, Moreover, the statistical properties of such beam propagating in free space are investigated in detail. It is found that, the propagation properties of the RPGSMA beams are closely related to initial beam parameters. With an appropriate choice of the beam parameters, the average intensity will evolve into optical lattice patterns, and the degree of coherence (DOC) from the lattice distribution on the original plane evolves into a Gaussian profile in the far field, and the degree of polarization (DOP) appears a periodical grid-like distribution on propagation. These results may be beneficial to particle trapping and free-space optical communications.

Published: July 2023

Background: Paraffin injection into the penis is one way that people see it as increasing penis size. But many do not know that paraffin injection actually causes side effects in the form of penile paraffinoma. This study aimed to describe the management of paraffinoma using bilateral techniques.

Case presentation: A 40-year-old married man came to the emergency room at Samuel J. Moeda Naval Hospital, Kupang, with complaints of pain and swelling of the penis for 6 hours. The pain felt to get worse when the penis was erected. The genital organs found swelling of the entire penile skin accompanied by tenderness and induration. The bilateral scrotal flap technique was because the scrotal skin had many blood vessels, good flexibility, little adipose tissue, thin skin, and could feel erogenous sensations almost the same as the physiological characteristics of the penile skin.

Conclusion: Bilateral scrotal flap technique on the penile shaft is a surgical technique that is quite effective in eradicating paraffin from penile tissue.
Legal Consequences of Violating the Endogamy Marriage System in Indonesia: A Study of Legislation
Authors: Gadjong Agussalim A.
Published: July 2023

This study aims to examine and analyze how sanctions are applied for violating the endogamous marriage system and linked in the context of the positive law system in Indonesia. This study uses normative legal research with conceptual, historical, and comparative approaches. The collected legal material is then qualitatively analyzed to describe the problem and answer study purposes. The results show sanctions and consequences for individuals violating the endogamous marriage system. Sanctions can range from social ostracism, status demotion to fines and withdrawal of access to resources. In religious endogamy, violations are considered sins, and marriages can be declared invalid under Law Number 1 of 1974. Violations of racial or ethnic and caste endogamy do not have formal legal consequences but can impact an individual’s social status. Therefore, it is recommended that authorities and community leaders continue educating individuals about the implications of these endogamous marriage systems. The need for open dialogues about the pros and cons of these systems is also essential. Furthermore, the Indonesian legal system should protect all individuals’ rights and uphold principles of equality and non-discrimination while respecting cultural and religious nuances.

Published: July 2023

Monitoring and evaluation is a critical component of project design, execution, and management. Kenyan county administrations have been carrying out development projects since 2013, but the completion of some of the development projects has faced serious implementation challenges. This study analysed the monitoring and evaluation practices that influence the implementation of a project that is financed by funds from the government. The targeted population comprised 113 staff working in the selected five departments in Meru County Government that deal with projects at the sub-county level. A sample size of 92 staff participated in the study. Staff was selected using the proportionate stratified together with a simple random sampling technique, while all heads of department were purposively picked. A questionnaire was distributed to staff while HODs were interviewed. Piloting enabled checking the reliability and validity of instruments. The mean and standard deviation helped to summarise the collected data. The results indicated that project funding, competencies of a project manager, employee capacity building and community participation were empirically confirmed to have significant weight on the successful implementation of projects. The study noted that reliable revenue streams, standards, best practices, and a well-designed financial plan are essential for the successful implementation of projects. The study recommends the need for the county government to allocate sufficient funding at the project’s inception to facilitate the acquisition of requisite equipment and finance initial operational activities. The government departments at the county level should prioritise enhancing the project management skills of staff involved in projects. The finishing of the identified projects is indispensable; hence, the results will change the manner in which government-funded projects are implemented by the county government.

Published: July 2023

Africa bears a heavy burden of diverse diseases which includes blood diseases that overwhelm the healthcare system. A multitude of factors were believed to be responsible for this burden and it includes a lack of trained healthcare workforce, multi-disciplinary research on diseases facing the region, and a dearth of advanced diagnostic and clinical services for haematologic disorders. Measures taken to improve the situation includes increased health budgetary spending which had marginally improved. The improvement thus far achieved in haematology and blood transfusion education and research need to be determined. Three databases, namely Google Scholar, PubMed and Core, were searched for literature on haematology and blood transfusion education and research. About 2616 articles were identified, of which 7 articles were included for the review following screening and eligibility assessment by independent reviewers. The articles reviewed revealed that there was a significant improvement in haematology and blood transfusion education and research. This has translated to an improved health workforce, service delivery and research capacity and profile. However, these gains were not quantifiably presented to judge the real progress against any set standards. To fully understand the progress made and the levels that need to be reached, a comprehensive, multifaceted, and multinational study that explicitly explores the improvement measures taken and their consequential outcome is necessary.
Solidarity in Catholic Social Teaching and Its Implications for Creating an Authentic Human Self
Authors: Ikeke Omorovie
Published: July 2023

The human self has been narrowly and erroneously understood in some quarters as simply purely scientific, naturalistic, individualistic, and materialistic. This understanding of the self has contributed to problems like selfishness, rugged individualism, materialism, get-rich-quick syndrome, ritual killings, genocidal wars, profiteering, and so forth. If these erroneous perceptions of the human person or self are left unchallenged, they will continue to degrade human society and dignity. This paper theorizes that the Catholic understanding of the human being as a social and communal being, thus implying solidarity, can help to recover the authentic human self. In this light, this paper uses the methods of critical analyses and hermeneutics to examine the Catholic understanding of solidarity and how it can help in retrieving the authentic human self. The paper finds that there are erroneous and narrow understandings of the human self and person. It concludes that the Catholic concept of solidarity can help to build an authentic human self and society.

Mallory-Weiss patients presents higher rate of active bleeding and need for endoscopic therapy compared to other causes of non-variceal upper gastrointestinal bleeding
Authors: López Vico M , López Tobaruela JM , Ortega Suazo EJ , Martínez Cara JG , Redondo Cerezo E , Jiménez Rosales R
Published: July 2023

Introducción: el síndrome de Mallory Weiss (SMW) se define como la presencia de laceraciones mucosas en la unión esofagogástrica asociado a hemorragia digestiva alta (HDA). Representa el 3-15% de todas las HDA. Tradicionalmente se ha considerado una causa benigna y autolimitada de HDA, pero estudios recientes han revelado una mortalidad similar al sangrado por úlcera péptica.

Objetivos:Comparar los resultados clínicos del SMW con otras causas de hemorragia digestiva alta no varicosa (HDANV).

Material y métodos:Se llevó a cabo un análisis retrospectivo de un registro prospectivo en el que se incluyeron a todos los pacientes con HDA tratados en el Hospital Universitario Virgen de las Nieves entre el 2013 y 2019. A todos los pacientes se le realizó una endoscopia digestiva alta (EDA). Se obtuvieron datos clínicos, bioquímicos y de evolución (durante el ingreso y diferidos).

Resultados:Del total de 698 pacientes con HDA, 535 presentaban HDANV, de los cuales 39 presentaron SMW y 496 HDANV no SMW (NSMW). Los pacientes con SMW se diferenciaron del resto en: antecedentes de cirrosis (28,2% vs. 15,3%; p=0,036); mayor consumo diario de alcohol en gramos (30,45 vs. 14,76; p=0,033); hematemesis al inicio (79,5% vs. 44,4%; p<0,001); sangrado activo en EDA (41% vs. 25,6%; p=0,036); necesidad de terapéutica endoscópica (53,8% vs. 23,9%; p=0,13).

Conclusiones: Los pacientes con SMW presentaron mayor riesgo de sangrado activo y necesidad de terapéutica endoscópica en comparación con otras causas de HDANV, por lo que debemos abandonar la idea del SMW como una causa benigna y autolimitada de HDA.

Published: July 2023

Actualmente existen distintos métodos para realizar el diagnóstico de la infección por Helicobacter pylori, sin embargo, no existe consenso oficial sobre el test óptimo para el diagnóstico, por lo que la elección se debe realizar en base a distintos factores. Uno de los factores que influyen en la elección del método diagnóstico es la necesidad o no de realizar gastroscopia para evaluar los síntomas o para seguimiento de patología digestiva existente, en función de esto se realizará un test diagnóstico invasivo o no invasivo. También influye la finalidad con la que el test se realiza: diagnosticar infección activa por H. pylori, comprobar la curación de la infección tras tratamiento erradicador o determinar la sensibilidad de la bacteria a los diferentes antibióticos tras fracaso de tratamiento erradicador previo. Otros determinantes que influyen son la prevalencia de la infección por H. pylori en la población, situaciones que produzcan reducción de la población bacteriana en la mucosa gástrica, como la presencia de sangrado digestivo activo o el uso reciente de ciertos fármacos (inhibidores de la bomba de protones, antibióticos, bismuto), la disponibilidad y coste del test.

La siguiente revisión pretende dar una visión general sobre los avances más recientes en los métodos diagnósticos para evaluar la infección por H. pylori y su interpretación, por lo que es necesario conocer las indicaciones precisas de cada test diagnóstico, conociendo sus ventajas y posibles defectos, así como los distintos escenarios en los que nos podemos encontrar sabiendo elegir el test diagnóstico más adecuado en cada situación.

MCS Selection Based on Convolutional Neural Network in TDD System
Authors: Oh Jeong-Eun , Jo A-Min , Jeong Eui-Rim
Published: July 2023

In this paper, a convolutional neural network (CNN) is proposed for selecting modulation and coding schemes (MCSs) at the time of future transmission in time-division-duplex (TDD) systems. The proposed method estimates the signal-to-noise ratio (SNR) obtained by the average of the equalizer’s output in the orthogonal frequency division multiplexing (OFDM) system and records it to select the most suitable MCS for future transmission. Two methods are proposed: one that directly selects an MCS and one that predicts the SNR first before selecting an MCS. The conventional method commonly used is to select an MCS based on the SNR of the most recently received signal. Computer simulations show that the outage probability and throughput of all proposed methods (direct and indirect) are superior to conventional methods (recent value). Shorter SNR sampling periods perform better than longer ones, and the accuracy of MCS selection decreases as mobile speed increases
A Diagnostic Study of Content-Based Image Retrieval Technique for Studying the CT Images of Lung Nodules and Prediction of Lung Cancer as a Biometric Tool

Content Based Medical Image Retrieval (CBMIR) can be defined as a digital image search using the contents of the images. CBMIR plays a very important part in medical applications such as retrieving CT images and more accurately diagnosing aberrant lung tissues in CT images. The Content-Based Medical Image Retrieval (CBMIR) method might aid radiotherapists in examining a patient's CT image in order to retrieve comparable pulmonary nodes more precisely by utilizing query nodes. Intending a particular query node, the CBMIR system searches a large chest CT image database for comparable nodes. The prime aim of this research is to evaluate an end-to-end method for developing a CBIR system for lung cancer diagnosis.
Performance Estimation of Improved Cooperative Spectrum Sensing under Fading Environment
Authors: Pandya Jay , Keraliya Divyesh
Published: July 2023

To deal with spectrum scarcity, Cognitive radio has been considered as a resolving technology. Energy detection(ED) is the most preferable sensing technique due to its lower complexity, ease of working and non-dependency on primary user data requirements. Although having many advantages, ED has some practical limitations like low SNR, shadowing, erroneous reporting channels and multipath fading. Here, a comparative study is done to check the effect of such parameters. And with simulation, it is proven that Cooperative spectrum sensing can reduce the effect of these confines. In this paper, we have also simulated the improved version of ED where decision making is done cooperatively. The results show that the performance of Improved Energy Detection (IED) is more efficient than the Classical ED, not only for AWGN, but also under fading environment. Cooperative spectrum sensing enhances the performance further. Under fading environment, the majority logic with centralized fusion centre performs better than other techniques. In this paper the performance estimation of Improved Energy Detection technique is done under Rayleigh fading environment and the positive effect of cooperation is also evaluated considering erroneous reports and imperfect reporting channels.
Theoretical and Methodological Aspects of the Early State Problem: A Socio-Philosophical Analysis
Authors:   Peoples’ Friendship University of Russia, Golubev Ivan S. ,   Lomonosov Moscow State University
Published: July 2023

This article deals with the phenomenon of the early state as a transitional societal stage between the pre-state and the developed state. Different views on the ways of transitioning to the state structure of public life in contemporary social science are analysed. The paper indicates a lack of a valid typology of forms of socio-political organization of society that is generally accepted by the majority of the scientific community. The object of this research is the phenomenon of the early state. The purpose of the article is to identify problematic theoretical and methodological aspects of using the term early state in the analysis of key strategies for understanding the origin of the state as a historically contingent form of socio-political organization. To achieve this purpose, a number of tasks are accomplished here: to consider the current state of research on the origin of the state; to identify theoretical ideas that are common to these studies; to analyse the content characteristics of the notion of the early state in the theories of leading political anthropologists and to compare their ideas about the essence of the early state. The scientific novelty of this paper lies in the problematization of the processes of politogenesis in terms of socio-philosophical consideration. This implies, first of all, a conceptual analysis of the prevailing views in contemporary science on the origin and essence of the state, which are reproduced in the studies of political anthropologists, describing the early state as a historically necessary form of socio-political organization. The author concludes that the current pluralism of approaches within social science to the analysis of the origin of the state and its relationship with the early forms of socio-political organization is mainly due to the underdeveloped criteria for distinguishing between the concepts of state and early state, which, naturally, makes it significantly harder to determine the key factors in transitioning to the state structure of society.
The Image of the “Coming Tsar” and the Mythologemes of Modern Eschatological Monarchism
Authors:   The Herzen State Pedagogical University of Russia, Prilutskiy Aleksandr M.
Published: July 2023

This article presents a hermeneutic analysis of the key concept of eschatological monarchism, i.e. the image of the coming eschatological tsar, whose accession to the throne is expected at the end of the world’s existence, shortly before the onset of the last apocalyptic events. Such mythologemes are particularly popular among Orthodox fundamentalists, the movement of tsarebozhniki (tsar worshippers), who endow the monarch and monarchy with a special sacred religious status. They commonly hold the idea that the modern Russian Federation is an illegitimate state. The author starts with analysing the modern Russian monarchical discourse, in which two varieties are distinguished: legitimism and eschatological monarchism. The latter consists of Orthodox-like subcultures, characterized by radical antiglobalism; Satanist Masonic conspiracy mythologemes; apostasy of the hierarchy of the Moscow Patriarchate; fight against ecumenism, modernism, crypto-Catholics, information technology, bank cards, documents, methods of encoding information, and modern technology. This phenomenon is based on the nostalgic mythologemеs of the Golden Age, idealizing the Russian Empire and the tsardom of Ivan the Terrible, as well as on the mythologemes of the heroic myth about the tsar as an invincible warrior hero defeating evil forces, and conspiracy mythologemes about the tsar as the only force capable of resisting powerful enemies-conspirators. The sources of monarchical eschatological mythologemes are mainly prophecies attributed, with varying degrees of certainty, to canonized saints or to non-canonized, but widely revered persons, as well as anonymous, pseudonymous and apocryphal texts. The coming eschatological tsar is not considered by the adherents as a successor to the Russian emperors: he is the first and only in his ranks. The nature of his use of monarchical power contains a mythological reference to the image of Ivan the Terrible. The image of the coming tsar is formed by a set of messianic ideologemes and mythologemes, such as “the coming tsar is an invincible military leader”, “the coming tsar will be feared by the antichrist himself”, “the tsar will cleanse the church of apostate hierarchs and various heretics”, “the form of government will be authoritarian and totalitarian”, “under the tsar’s rule, Russia will become the most powerful state in the world” or “under the tsar’s rule, Russia will be a materially poor, but spiritually rich state”.
O inconveniente cotidiano diante do Salazarismo: As Casas, de Luiza Neto Jorge, contra os fundamentos da Casa Portuguesa
Authors: Campello Paula
Published: July 2023

Este artigo observa como as figurações do espaço e da vida domésticos presentes na série de poemas As Casas, de Luiza Neto Jorge, contrapõem­-se a discursos e práticas conservadoras que entendem o lar como lugar de modéstia, estabilidade e clareza. O estudo confronta uma leitura dos poemas a políticas e à propaganda do Salazarismo, regime ditatorial no poder em Portugal no período em que os poemas foram publicados, em 1964. A pesquisa compara os poemas também à proposta estética do ar­quiteto Raul Lino, que no livro A Casa Portuguesa descreve as casa popu­lares lusitanas como o produto de um suposto “sentir português”, afeito à simplicidade.
