Published: March 2023

Nghiên cứu được thực hiện với mục đích mô tả đặc điểm hình ảnh cộng hưởng từ động sàn chậu của bệnh lý sa bàng quang ở nữ giới có rối loạn chức năng sàn chậu. Chúng tôi thực hiện nghiên cứu mô tả cắt ngang các bệnh nhân có hình ảnh sa bàng quang trên phim chụp cộng hưởng từ động sàn chậu tại bệnh viện Hữu nghị Việt Đức từ 7/2019 đến 7/2022. Nghiên cứu được thực hiện trên 58 bệnh nhân, tuổi trung bình là 59,17 tuổi. Cộng hưởng từ động sàn chậu bộc lộ rõ hình ảnh sa bàng quang ở thì rặn tống phân. Độ hạ thấp cổ bàng quang tăng lên ở thì rặn so với thì nghỉ và tăng lên cùng với mức độ sa bàng quang p < 0,01. Niệu đạo quá di động được chẩn đoán ở 100% các bệnh nhân. Ở thì rặn, chiều dài thành trước âm đạo tăng lên có ý nghĩa so với thì nghỉ, và tăng cùng với mức độ sa bàng quang với p < 0,05. Độ sa bàng quang có mối liên quan với độ mở sàn chậu theo H với p < 0,01, nhưng không có mối liên quan với độ sa sàn chậu theo M với p > 0,05. Cộng hưởng từ động sàn chậu cho thấy là phương pháp giúp đánh giá một cách toàn diện bệnh lý sa bàng quang và các bệnh lý sàn chậu khác đi kèm để từ đó giúp lựa chọn phương pháp điều trị phù hợp cho từng bệnh nhân.

Authors: Đạt Vũ Quốc , Hiệp Nguyễn Lê
Published: March 2023

Tổ chức Y tế Thế giới khuyến cáo nếu xét nghiệm creatinin thường quy, cần ước tính mức lọc cầu thận trước khi điều trị phác đồ có tenofovir. Chúng tôi tiến hành nghiên cứu hồi cứu những bệnh nhân bệnh nhân > 18 tuổi được chẩn đoán HIV tiến triển tại các cơ sở điều trị ARV tại 15 tỉnh, thành phố tại Việt Nam từ tháng 1/2021 đến 5/2022. Nghiên cứu này được thực hiện tại 15 tỉnh, thành phố tại Việt Nam. Chức năng thận được đánh giá theo ước tính mức lọc cầu thận (eGFR) sử dụng công thức MDRD (Modification of Diet in Renal Disease). Tỉ lệ bệnh nhân có eGFR < 60 ml/min/1,73m2 là 6,0% (108/1787). Các yếu tố liên quan đến mức lọc cầu thận thấp (eGFR < 60 ml/min/1,73m2) là giới tính nữ (OR = 4,07, 95%CI: 2,71 - 6,08), hemoglobin thấp (OR = 1,86, 95%CI: 1,01 - 3,22) và tuổi (OR 1,07, 95%CI: 1,05 - 1,09). Trên những bệnh nhân xác định được tình trạng sống còn, tỉ lệ tử vong ở bệnh nhân có và không giảm mức lọc cầu thận là 11,5% (7/61) và 7,5% (99/1326). Tỉ lệ giảm chức năng thận thường gặp ở bệnh nhân HIV nên cần thiết phải đánh giá chức năng thận trước khi bắt đầu điều trị ARV và theo dõi định kỳ trong quá trình điều trị.

Authors: Atmaja Ilham Hardina , Oktavia Dina , Angesti M. Farandi
Published: March 2023

This study aims to determine the export competitiveness of East Java manufactured products based on the harmonized system (HS) through Revealed Comparative Trade Advantage (RTA) analysis to cluster superior manufacturing products in the districts/cities with the largest share of the manufacturing industry using Location Quotient (LQ), as well as analyzing the determinants of East Java exports based on the destination country of trading partners in the short and long term using the Vector Error Correction Model (VECM). The results show that the RTA value of East Java is still competitive in terms of exports of manufactured commodities. In addition, the LQ analysis also concludes that there are industrial agglomerations, namely industries that are close to each other and form industrial areas, such as in Surabaya-Gresik-Sidoarjo-Malang. On the other hand, the short-term and long-term modeling shows that the GDP per capita of partner countries plays a crucial role in the sustainability of East Java’s exports. This result lead to several policy recommendations, such as preventing the demand shock from partner trading country especially non-ASEAN countries, either price and exchange rate volatility or political events as well as strengthening strategy to focus commodity production for export-oriented products.

Asset Tangibility and Financial Performance: The Moderating role of Economic Growth and Earnings Volatility
Authors:   Jaramogi Oginga Odinga University of Science and Technology, Kenya, Oganda Aloys Jared
Published: March 2023

The Kenyan manufacturing sector’s contribution to the economy has been declining. It has stagnated at 10% of the gross domestic product (GDP), contributing to an average of 10% from 1964-1973 and marginally increased to 13.6% from 1990-2007 and has been below 10% in recent years further dropping to 8.4% in 2017 and 7.1% in 2020 ultimately hitting its lowest in 2022 of 7.2%. The government has renewed its efforts to revive the sector to grow its contribution to GDP to 20% by 2030. Asset tangibility is a significant determinant of how counterparties and external financiers value a firm and hence turn around its fortunes. This study applied Dynamic Unbalanced Panel analysis techniques using Secondary data for 10-year period (2010 - 2019) with the study population comprising of 9 listed firms. A census of the firms was done and resulted to 86 observations. Focus was on asset tangibility moderated by economic growth rate and earnings volatility on firm value which was proxied by Tobin’s Q and EVA. Pecking order guided the study. Longitudinal research design was used as it is appropriate when dealing with panel data. STATA version 15 was used for analysis. Model estimation followed a two Step System GMM testing the study hypotheses at 5 % significance level. Pearson correlation coefficient was used to show the strength and direction of association among the study variables. ATNG was positively correlated with Tobin Q (r = 0.4331) and LnEVA (r = 0.3683). The regression weights were also positive and significant. The study therefore concluded that asset tangibility is imperative as it directly determines the financial burden firms face in their operations and recommended that the managers of manufacturing firms need to consider project financing to limit exposure to credit risk. Future studies can consider a balanced panel analysis and other panel data econometric techniques. Keywords: Asset tangibility, Firm Value, Financial Performance, Manufacturing firms.

Authors:   University of Westminster, London, UK, Krishnamohan Theviyanthan
Published: March 2023

Swarm robotics applies swarm intelligence to robotics to solve real-life problems that cannot be solved by single, monolithic robots. This review first studies swarm robotics in depth and analyzes the different types of tasks carried out by swarms of robots. Then, the consensus-achievement behavior is elaborated on and its relation to the collective perception scenario is reviewed. The collective perception scenario is expounded in detail and the three discreet consensus-achievement strategies, namely the direct modulation of majority-based decision, direct modulation of voter-based decision, and direct comparison are discussed apropos of the collective perception scenario. This review then compares these strategies and explores their shortcoming such as the vulnerability to Byzantine robots.

Machine Learning of polymer types from the spectral signature of Raman spectroscopy microplastics data
Authors: Ramanna Sheela , Morozovskii Danila , Swanson Sam , Bruneau Jennifer
Published: March 2023

The tools and technology that are currently used to analyze chemical compound structures that identify polymer types in microplastics are not well-calibrated for environmentally weathered microplastics. Microplastics that have been degraded by environmental weathering factors can offer less analytic certainty than samples of microplastics that have not been exposed to weathering processes. Machine learning tools and techniques allow us to better calibrate the research tools for certainty in microplastics analysis. In this paper, we investigate whether the Raman shift values are distinct enough such that well studied machine learning (ML) algorithms can learn to identify polymer types using a relatively small amount of labeled input data when the samples have not been impacted by environmental degradation. Several ML models were trained on a well-known repository, Spectral Libraries of Plastic Particles (SLOPP), that contain Raman shift and intensity results for a range of plastic particles, then tested on environmentally aged plastic particles (SloPP-E) consisting of 22 polymer types. After extensive preprocessing and augmentation, the trained random forest model was then tested on the SloPP-E dataset resulting in an improvement in classification accuracy of 93.81% from 89%.
EuclidNet: Deep Visual Reasoning for Constructible Problems in Geometry
Authors: Wong Man Fai , Qi Xintong , Tan Chee Wei
Published: March 2023

In this paper, we present a visual reasoning framework driven by deep learning for solving constructible problems in geometry that is useful for automated geometry theorem proving. Constructible problems in geometry often ask for the sequence of straightedge-and-compass constructions to construct a given goal given some initial setup. Our EuclidNet framework leverages the neural network architecture Mask R-CNN to extract the visual features from the initial setup and goal configuration with extra points of intersection, and then generate possible construction steps as intermediary data models that are used as feedback in the training process for further refinement of the construction step sequence. This process is repeated recursively until either a solution is found, in which case we backtrack the path for a step-by-step construction guide, or the problem is identified as unsolvable. Our EuclidNet framework is validated on the problem set of Euclidea with an average of 75% accuracy without prior knowledge and complex Japanese Sangaku geometry problems, demonstrating its capacity to leverage backtracking for deep visual reasoning of challenging problems.

Published: March 2023

The shelf life of Dalsha, Peter, Broken mango (Mangifera indica L) species was extended using the extract of some natural preservatives such as Tumeric, Lemon grass and Neem Leaves. The result of the storage studies showed that Dalsha and Peter mangoes had a shelf life of 48 days each as against 8 and 9 days respectively while broken mango had a shelf life of 54 days as against 12 days for the control, result of the physiochemical characteristics showed that pH of the controlled fruit dropped from 3.85-2.91, 3.84-2.93 and 3.82-2.82 for Dalsha, Peter and Broken respectively. The pH value for each sample decreased with storage time. Titratable acidity (TA) showed a gradual decrease with storage time. Total soluble solids (TSS) increased with storage time. The sensory analysis reveals that turmeric treatment showed best scale point of 1 for all parameters whereas controlled samples showed poor scale point. Results of the weight loss indicates that fruits treated with the extract showed lower percentage weight loss as compared to the control generally, weight loss increased with storage time throughout the storage period. The antimicrobial sensitivity revealed that all the fungi and bacteria except Aspergillus Spp and Fasarium were susceptible to all the plant extracts. Thus, the use of natural preservatives (Turmeric, Lemon grass and Neem leaves extract) have shown to be a good and cheap alternative method of preventing post- harvest decay and loses through preservation and shelf life extension of the fruits upon treatment with the extract.

Published: March 2023

Purpose: Finger injuries are important causes of emergency department admissions. In order to perform daily activities, the fingers must work fully and flawlessly. Replantation surgery aims to keep the injured finger alive and perform its functions almost completely. Our study aims to evaluate the reasons affecting the success of replantation during the SARS COV-2 pandemic period and to question the functional recovery after replantation.
Methods: Finger and hand replantation performed in a single center by the same surgeon were reviewed retrospectively. Preoperative, intraoperative, and postoperative and demographic data of the patients, mechanism of injury, ischemia duration, complications, surgical treatment approaches, and functional evaluation scales after rehabilitation were collected and statistically evaluated.
Results: In our study, 88 fingers of 56 patients were replanted. While single finger replantation was performed in 38 patients, multi-finger replantation was performed in 18 patients. The total success rate of replantation was 73.2%. While successful results were obtained in 81.6% of 38 patients with single finger replantation, 55.6% of 50 fingers in 18 patients with multiple finger replantation were successful. We found that 3 patients after surgery and 11 patients in the six months before surgery were positive for SARS COV-2. No finger loss or complications occurred in these 14 patients after replantation.
Conclusion: We concluded that SARS COV-2 disease had no significant effect on finger replantation surgery. Our study found that the most important variables affecting surgical success were the mechanism of injury, injury level, age, gender, anesthesia technique applied, number of repaired veins, smoking, and ischemia duration.

Authors: Shrikrishna Rajagopala , No author No author , P Karthik
Published: March 2023

Kaumārabhr̥tya or Bālacikitsa has transcended the tests of time. It has been an area of proactive practice in several parts of the nation. Pediatrics is a promising field not only in Ayurveda but in Siddha (Kuzhantai maruttuvam/Bālavagadattiruṭṭu) and Unani (Amraz-e-Atfal) too. These traditional branches of pediatrics are at crossroads. The public notion that the indigenous, traditional interventions suit their children better has probably led to an increased preference towards these systems. On the other side, for these practices to remain current and find their deserving space in community health, it needs much more evidence.
Health promotion and disease prevention Svarṇaprāśana is one of the most important contributions of Kaumārabhr̥tya to society. It is like presenting ‘old wine in new bottle’ – a new beacon in Ayurveda Pediatric practice. It is the experience of many learned practitioners of Ayurveda and research outcomes in specific that Svarṇaprāśana acts as a positive adjuvant to many existing therapies and boost the cure and recovery rate and many a times acts as a sure shot remedy too! Its use as a prophylactic immunomodulator and nootropic has become a widespread practice all over the country owing to
its safety and effectiveness in these domains. In biomedicine as well, gold is an emerging broad- spectrum therapeutic agent in cancer, respiratory illnesses, pain, and cognitive impairments. Non- gold preparations having prophylactic and immunomodulatory actions are also common in practice as parts of vernacular traditions, like Uraimarunnu in the south and Janma ghunti in the north. Prākāra yogas are immunomodulators specific to children, mentioned in Ārogyakalpadruma (pediatric treatise).

-Since the late 1970s, there has been talk of home automation. Yet, as technology and services improved, so did people's expectations, which affected how they perceived home automation systems. In this work, we use a modest PIR built around an Arduino controller to construct an advanced electronic security system. PIR and IR sensors detect an intruder's presence, and the controller interprets the signal from the sensors. Intruder detection activates the bell, places a call, and sends an SMS to a predetermined number using a GSM modem. In tandem, the controller activates a camera to record an intruder's image and send it to the person via GSM module AT instructions.A excellent security system is centrally located, making it easy to maintain a close eye on the entire area, which lowers personnel requirements and labour costs.

The importance of Concurrent Engineering is rising as businesses compete in the global market. The primary variables that influence a company's success are the reduction of time spent on product creation, the improvement of product quality, the reduction of production costs, and the satisfaction of consumers. The idea of Concurrent Engineering has to be put into practice if high-quality goods are to be produced. It is a methodical strategy that succeeds when all design tasks are combined and carried out simultaneously. Many businesses' product development processes have been overhauled as a direct result of the Concurrent Engineering strategy. Therefore, the purpose of this study is to analyze the use of Concurrent Engineering in the automobile sector by reviewing its fundamental ideas and tools. In the same way, doing a thorough market study and meticulously planning every step of the design process are essential in a Concurrent Engineering setting. By keeping "avoidable" expenses out of the design in the early phases, the Concurrent Engineering method may lead to substantial savings. It is also sometimes called "Simultaneous Engineering."

Acoustic levitation is a fascinating phenomenon that has captured the attention of researchers and engineers for many years. This project aims to explore the possibilities and potential applications of acoustic levitation technology. Using an array or a couple of ultrasonic transducers, we were able to create a standing wave that allowed us to levitate small objects, such as water droplets and tiny plastic beads. We investigated the effects of different parameters, such as frequency and amplitude, on the levitation process. Various applications demonstrate the potential of acoustic levitation such as drug delivery, microfabrication, and even space exploration. This project highlights the exciting possibilities of acoustic levitation technology and lays the foundation for future research in this field.

Financial Perspective Thought Experiment on Russian Cyber Threat Actors
Authors: Bederrna Zsolt
Published: March 2023

Due to the advancement of information and communication technology and related services, the digital world has reached many people, private companies, and governments, and meanwhile, threat actors regarding motivation, knowledge, and capabilities have also evolved, and thus, today, they compete and collaborate with others. Financially motivated threat actors also do businesses; as such, with a higher sophistication level, they create tools and provide them as Malware as a Service (MaaS) for renting, and if they can extract accounts, they launder those amounts of cash through hardly traceable channels. In contrast, state-sponsored threat actors act according to the government’s political and military needs.

The Russian government lets independent threat actors freely conduct various cyberattacks, including cyber espionage, sabotage, and ransomware attacks on non-Russian geolocations and entities, meanwhile financing its threat actors to achieve social and political activities. As such, providing a thought experiment, the paper examines the potential income of a for-profit organization, the related tax income, and the costs of operating a government-related threat actor. To conduct the analysis, it provides a methodological approach and applies that to TA542 and APT28 threat actors, using inputs from open-source intelligence.
Uncovering The Sociological Interpretation of Visual Impairment-Related Inequities and Their Social Determinants in India
Authors: M Chandrashekher , Satpathy Suchismita
Published: March 2023

Introduction: Determinants of health are divided into four types, such as “Biological-Psychological-Environmental-Social Determinants”. The social determinants of health include gender disparities, economic status, ethnicity, race, geographic isolation, or having a specific health condition. Moreover, the social determinants are interdependent and interrelated with one another. There can also be a primary determinant that affects the other determinants. For example, educational level of the patients is associated with knowledge and awareness of eye care and its conditions. However, education might have a different effect than income in should be access of eye care when needed.
Methodology: The study is mainly dependent on secondary data analysis.
Results: The primary objective of the study is to illustrate the sociological aspects of visual impairment-related inequities and to identify the social determinants of visual impairments and disparities in India. Another aim of the paper is to present a deeper understanding of how inequities impact the incidence of visual impairment and blindness based on the social determinants of health. The present study adopts the ecological and Commission on Social Determinants of Health (CSDH) framework 2008. We reaffirm the fact that inequities negatively affect the visual impairment and blindness conditions. The national health policies should take into account the social determinants of visual impairment in their policies relating to comprehensive eye care.  Social and economic factors are connected with health and welfare; those socio-economic inequalities contribute to health inequalities. For reducing the health inequalities around the world, we need effective policy implementation and proper fund pools. Furthermore, committed action on societal determinants of health, sufficient human resources are also necessary to control the health disabilities, include visual impairment.

Context/Background: Today, poor mental health is one of the most neglected diseases although it is one of the leading causes of disabilities in both developed and developing countries. This mental health issue becomes a problem among university students too. This study was aimed to determine the prevalence and associated factors of depression, anxiety, and stress (DAS) among university students.
Methodology: A cross-sectional study was carried out in a private university of northern Malaysia during 2020. A random sample of 161 students were included and DASS-21 was used to determine the prevalence of DAS. Multiple logistic regression analysis was performed to examine the associated factors.
Results: The prevalence of DAS among students were 34.8%, 42.2%, and 33.5%, respectively. In contrast to years 2 and 4, the prevalence of all types of mental disorders were lower in years 1 and 3. The students’ living area, residence, academic year, and parental income were significantly associated with anxiety whereas the age group of the students and parent’s income did so for depression. The variables; age group, academic year and parent’s income were identified as significant determinants for the presence of stress among students.
Conclusions: The significant extent of the mental health problems was detected among university students in Malaysia. Despite the small sample, this analysis indicates that opportunities exist to improve campus-based mental health education and psychological support among university students.
Internet Searching of Client Information by Social Workers: Reckless or Required in Today’s Online Society?
Authors: Apgar Dawn , Cadmus Thomas
Published: March 2023

Telehealth and social media raise ethical issues for social workers, prompting the National Association of Social Workers (NASW) to revise ethical standards in recent years to address use of technology. Social workers are directed to avoid searching client information electronically but may do so with clients’ informed consent. Professional technology standards and directives from NASW indicate that the information gathered on the Internet about clients is distinct from that obtained from clients directly. While internet searching of clients is widely used in business and other professions, its value in social work has been largely unrecognized. This article lends support for viewing internet information on clients as critical data that should be routinely gathered by social workers in many instances, justifying its importance in light of the ecological perspective which is the foundation of social work practice. Gathering internet information on clients is valuable to understanding people in their environments, as much of daily life now takes place in the digital world. Recommendations assist social workers to responsibly engage in internet searching of client information so that it can be incorporated into social work’s standard of care. Keywords: Ethics, ecological perspective, technology, social media

Image Processing Techniques for COVID-19 Detection in Chest CT
Authors: Abdul-Adheem Wameedh , Ahmed Sanaa
Published: March 2023

COVID-19 virus is a disease that has spread around the world recently. Early diagnosis of the disease leads us to the opportunity to treat patients faster to reduce its spread in the community. The CT scan image is one of the routines used to diagnose the COVID-19 diseases in an efficient manner and in a faster time. Fractal Dimension which mean (fragmented or irregular) used in wide range of image processing and analysis applications to get the self- similarity of images. To classify textures, combine images, segment and compress images and to generate incredibly complex and good-looking images, the Fractal Dimension method is used. Moreover, Euler method uses features to explain the structural property caused by noise in binary images. It also describes the topological features and analyze the texture of images. In this paper, a method is proposed to obtain the features of CT scan images for COVID-19 by using a hybrid technique called Fractal Dimension Euler (FDE), which merges the two methods of image processing (Fractal Dimension method and Euler Number Method). The two algorithms aim to segment the CT-scan images for the chest to distinguish between the affected and uninfected area of the chest to detect the COVID-19. The results of the proposed approach were very useful in comparison with another approach, the FD method was applied to CT scan images for COVID- 19 using a method called box counting. After that, the Euler method was used to distinguish between foreground and background by using a threshold value. The best threshold value was (255) which achieved the finest result.
