Authors: Klier Kristina , Koch Lucas , Graf Lisa , Schinköthe Timo , Schmidt Annette
Published: November 2023

BACKGROUND

To date, the 12-lead electrocardiogram (ECG) is the gold standard for cardiological diagnosis in clinical settings. With the advancements in technology, a growing number of smartphone apps and gadgets for recording, visualizing, and evaluating physical performance as well as health data is available. Although this new smart technology is innovative and time- and cost-efficient, less is known about its diagnostic accuracy and reliability.

OBJECTIVE

This study aimed to examine the agreement between the mobile single-lead ECG measurements of the Kardia Mobile App and the Apple Watch 4 compared to the 12-lead gold standard ECG in healthy adults under laboratory conditions. Furthermore, it assessed whether the measurement error of the devices increases with an increasing heart rate.

METHODS

This study was designed as a prospective quasi-experimental 1-sample measurement, in which no randomization of the sampling was carried out. In total, ECGs at rest from 81 participants (average age 24.89, SD 8.58 years; n=58, 72% male) were recorded and statistically analyzed. Bland-Altman plots were created to graphically illustrate measurement differences. To analyze the agreement between the single-lead ECGs and the 12-lead ECG, Pearson correlation coefficient (r) and Lin concordance correlation coefficient (CCCLin) were calculated.

RESULTS

The results showed a higher agreement for the Apple Watch (mean deviation QT: 6.85%; QT interval corrected for heart rate using Fridericia formula [QTcF]: 7.43%) than Kardia Mobile (mean deviation QT: 9.53%; QTcF: 9.78%) even if both tend to underestimate QT and QTcF intervals. For Kardia Mobile, the QT and QTcF intervals correlated significantly with the gold standard (rQT=0.857 and rQTcF=0.727; P<.001). CCCLin corresponded to an almost complete heuristic agreement for the QT interval (0.835), whereas the QTcF interval was in the range of strong agreement (0.682). Further, for the Apple Watch, Pearson correlations were highly significant and in the range of a large effect (rQT=0.793 and rQTcF=0.649; P<.001). CCCLin corresponded to a strong heuristic agreement for both the QT (0.779) and QTcF (0.615) intervals. A small negative correlation between the measurement error and increasing heart rate could be found of each the devices and the reference.

CONCLUSIONS

Smart technology seems to be a promising and reliable approach for nonclinical health monitoring. Further research is needed to broaden the evidence regarding its validity and usability in different target groups.

BACKGROUND

In the long wait for a vaccine against COVID-19, several pharmaceutical companies developed highly effective and safe vaccines. However, how people are reacting to the significance and usage of those vaccines is another pertinent issue?

OBJECTIVE

This study explores the perceptions and attitudes towards the importance of the COVID-19 vaccine and its potential side effects among people in the Philippines and Malaysia.

METHODS

A total of 4114 participants from the Philippines (n=1002) and Malaysia (n=1556) were recruited for this study. Bivariate and multivariate analysis techniques have been used. In descriptive analyses, the Chi-square test was used to compute absolute frequency and relative frequency (percentages) across the two countries. Three different adjusted models were employed to run ordered logistic regression.

RESULTS

The majority (over 60%) of participants rated all the COVID vaccine-related information as important in both countries. Vaccine acceptance was lower in Philippines as compared to Malaysia as only two-fifths (43.41%) of the Philippines’ respondents stated that everyone should get vaccinated in comparison to almost three-fourths (77.06%) of respondents in Malaysia. Respondents were two times [OR: 2.17; CI: 2.06-2.29] more likely to report that vaccine is safe to use. The odds of people believing that a vaccine can help control the spread of COVID-19 were almost two times higher [OR: 1.90; CI: 1.82-1.99] than the belief that the COVID-19 vaccine cannot help in controlling the spread of COVID-19. The importance of vaccine for health was lower among employed respondents [OR:0.83; CI:0.72-0.94] than in the respondents who were not employed. After controlling all the confounder factors, the odds of concern that the vaccine could cause serious reactions were higher [OR: 1.57; CI:1.48-1.67] among respondents.

CONCLUSIONS

The adherence to COVID-19 preventive measures will need to be monitored closely as restrictive measures are being relaxed and as the expectations concerning the COVID-19 vaccine may decrease the motivation of people to adhere to prevention measures. With the advent of mass vaccination to quell the COVID-19 pandemic, the distribution of strategically placed public health information regarding COVID-19 vaccination, delivered in locally customized and culturally appropriate language.
A Theory and Evidence-Informed e-Cycling Intervention for Individuals Diagnosed With Cancer: Development Study (Preprint)
Authors: Bourne Jessica E , Kelly Paul , Armstrong Miranda E G
Published: November 2023

BACKGROUND

Physical activity engagement following a cancer diagnosis is positively associated with survival, reduced risk of disease recurrence, and reduced cancer-specific and all-cause mortality. However, rates of physical activity engagement are low among individuals diagnosed with and being treated for breast cancer or prostate cancer.

OBJECTIVE

The purpose of this study was to describe the systematic process of developing an e-cycling intervention aimed at increasing physical activity among individuals living with prostate cancer or breast cancer and outline the key components to be implemented.

METHODS

The Medical Research Council guidance for developing complex interventions and the Behaviour Change Wheel were used to guide intervention development. Information was gathered from the literature and through discussions with end users to understand factors influencing e-cycling. These factors were mapped onto the Theoretical Domains Framework to identify potential mechanisms of action. Behavior change techniques were selected from theory and evidence to develop intervention content. Interested parties, including cycling instructors, end users, and behavior change experts, reviewed and refined the intervention.

RESULTS

Anticipated barriers and facilitators to e-cycling engagement were mapped onto 11 of the 14 domains of the Theoretical Domains Framework. A total of 23 behavior change techniques were selected to target these domains over 4 one-to-one e-cycling sessions delivered by trained cycling instructors in the community. Cycling instructors were provided a 3-hour classroom training session on delivering the intervention and a 3-hour practical session with feedback. The outcome of this work is a theory and evidence-informed intervention aimed at promoting e-cycling behavior among individuals being treated for breast cancer or prostate cancer, which is currently being implemented and evaluated.

CONCLUSIONS

Transparent intervention development and reporting of content is important for comprehensively examining intervention implementation. The implementation of this intervention package is currently being evaluated in a pilot randomized controlled trial. If the intervention is found to be effective and the content and delivery are acceptable, this intervention will form a basis for the development of e-cycling interventions in other survivors of cancer.

CANCER AND NEW PROSPECTIVE TO TREAT CANCER
Authors: MEHDI SHIRAZ , CHAUHAN AYUSH , DHUTTY AYUSH
Published: November 2023

Cancer is a condition when a few of the body's cells grow out of control and spread across other bodily regions. In the millions of cells that make up the human body, cancer may develop practically anywhere. Human cells often divide (via a process known as cell growth and multiplication) to create new cells when the body requires them. New cells replace old ones when they die as a result of ageing or injury. Aside from recent significant advancements in stem cell treatment, targeted therapy, ablation therapy, nanoparticles, natural antioxidants, radionics, chemodynamic therapy, sonodynamic therapy, and ferroptosis-based therapy, traditional treatment modalities like surgery, chemotherapy, and radiotherapy are still in use. Oncology practices today concentrate on creating effective and secure cancer nanomedicines. Targeting both primary and metastatic cancer foci, stem cell treatment has demonstrated remarkable success in regenerating and repairing sick or damaged tissues, and nanoparticles have introduced novel diagnostic and therapeutic possibilities. The development and spread of particular cancer cells can be prevented by targeted treatment, which also protects good cells from harm. Ablation treatment has become a less invasive method for freezing or burning tumours without performing open surgery. Natural antioxidants have shown promise in locating free radicals and counteracting their damaging effects, perhaps treating or preventing cancer. Clinical trials are being conducted on a number of innovative technologies, some of which have already received approval. A summary on current developments and discoveries in cancer therapy was provided in this review.

Authors: DONKA BHARGAVI , MAHAJAN HEMENDER , SHARMA NALNEESH
Published: November 2023

Objective: Thyroid disorders, particularly hypothyroidism, pose significant risks to both pregnant women and their fetuses. This prospective observational study aimed to investigate the prevalence and clinical implications of hypothyroidism among pregnant women in the first trimester in a hilly region of North India.

Methods: The study included 300 pregnant women attending the antenatal clinic at Shri Lal Bahadur Shastri Government Medical College and Hospital, Mandi (HP), between April 1, 2021, and March 31, 2022. Participants were categorized into two groups based on their thyroid-stimulating hormone (TSH) levels: Group A (TSH 2.5-10.0 mIU/l) and Group B (TSH>10 mIU/l). Thyroid function was assessed through TSH, free T4, and free T3 measurements. Maternal and fetal outcomes were monitored throughout pregnancy.

Results: The study found an overall hypothyroidism prevalence of 11.31%, comprising 10.98% subclinical hypothyroidism (SCH) and 0.33% overt hypothyroidism (OH). These findings were consistent with similar studies in North India. Participants had a mean age of 28.7±5.2148 y, resembling demographic data from hilly regions. A majority of participants belonged to the lower-middle-income group and resided in rural areas, reflecting the socio-demographic distribution in the region. The gestational age ranged from 6 to 12 w, with an average of 9.31±1.5 w. The average TSH level was notably higher than in other Indian studies, potentially due to the geographical altitude.

Conclusion: The study highlights the need for early detection and management of thyroid dysfunction during pregnancy, especially in hilly regions, to prevent maternal and fetal complications. This research addresses a knowledge gap and emphasizes the importance of thyroid screening during the first prenatal visit in similar settings.
Importance of Program Evaluation in English Language Education
Authors: Chalikandy Dr. Muhammedali
Published: November 2023

The purpose of this paper is to discuss the importance of program evaluation in English language education. Evaluation is a part of our life and we often evaluate every aspect of our life. We make value judgment like ‘The film is super’, ‘He is a nice person’ or ‘She is very kind’ etc. In fact, we are good at negatively evaluating others very often. These judgments are based on our feeling towards them and our preferences. Such type of everyday casual judgment can become a piece of research if there is a question, data analysis and interpretation of the data. The paper explains the meaning and types of evaluation and it argues that program evaluation is very important in English language education since it provides evidence for improvement, consolidation, refinement and modification of the program. This paper also discusses the possible evaluators of the program, types of information needed for the evaluation and the methods to be used in evaluating an English language educational program. Furthermore, the paper explores some practical steps for designing a program evaluation.

Research on Remanufacturing Process and Its impact on the Environment
Authors: Chaudhari Sakshi
Published: November 2023

Abstract: With sustainable industrial development, Remanufacturing has gained immense popularity. Attempts are made to rebuild new products while maintaining the quality equivalent to that of newly manufactured products. The need to study and apply the concept of Remanufacturing on a large scale arises due to the limited availability of resources on the planet Earth. Remanufacturing is a process of restoring a non-functional, discarded, or traded-in product like-new condition. It results in 68- 83% reduced energy, material use, and production costs. Environmentally, remanufacturing facilitates a decrease in 73-87% fewer carbon dioxide emissions. Remanufacturing has become a critical element of the circular economy wherein products are developed, manufactured, used, and recovered to prevent any sort of waste and reduce the extraction of raw materials. Despite successful growth in Remanufacturing industry, it continues to face numerous challenges but holds the potential to become a multi-billion-dollar industry. The paper discusses the process of Remanufacturing, its design aspects, and the environmental impact. It also provides case studies for explaining the Remanufacturing of Engines.

Published: November 2023

Введение. На напряженно-деформированное состояние каркаса многоэтажного здания оказывают влияние дефекты и отклонения от проектного решения. качество строительного объекта зависит не только от качества проектирования и изготовления, но и от качества строительно-монтажных работ. При монтаже строительных конструкций основной целью является обеспечение требуемого по проекту пространственного положения элементов строительных конструкций. для рамного каркаса с жесткими сопряжениями элементов отклонения от проектного положения ведут к росту изгибающих моментов, что может вызвать более раннее исчерпание несущей способности. актуальность исследования заключается в разработке методики проектирования рамных стальных каркасов многоэтажных зданий с учетом погрешностей изготовления и монтажа.

Материалы и методы. Оценка влияния начальных несовершенств была выполнена на примере рамного каркаса 10-этажного жилого здания. для расчета использован вычислительный комплекс лира-СаПр 2021. начальные несовершенства каркаса приняты в соответствии с действующими российскими нормами. кроме прямого учета искаженной геометрии проводились расчеты с дополнительными распределенными горизонтальными нагрузками, прикладываемыми на каждом этаже по методике еврокода 1993-1-1. Полученные разными способами перемещения и усилия характерных точек и сечений каркаса сравнивались друг с другом. расчет выполнен на сочетание постоянной, снеговой, полезной и ветровой нагрузок.

Результаты. Учет погрешностей сборки и изготовления в геометрии каркаса позволяет более точно учесть влияние погрешностей по сравнению с методикой еврокода. Перемещения и усилия, полученные линейным расчетом рамного каркаса, мало отличаются от результатов нелинейного расчета.

Выводы. Установлено, что прямой учет погрешностей изготовления и сборки каркаса в геометрии расчетной схемы дает возможность более точно оценить работу каркаса. использование методики еврокода с дополнительными горизонтальными нагрузками на уровне каждого этажа ведет к получению завышенных перемещений и усилий по сравнению с фактическими.

Published: November 2023

Geçmişten günümüze birçok müzikle tedavi uygulamaları yapılmış ve bu uygulamalar sonucunda hastalığa iyi gelen tedaviler bulunduğu tespit edilmiştir. Türklerin İslamiyet’i kabul ettiğinden günümüze kadar bu tedavi yöntemleri, İslamiyet öncesinde, İslamiyet sonrasında, Selçuklularda, Osmanlılarda ve günümüzde bu hastalıkları tedavi etmek amacıyla kurulmuş tedavi merkezleri ile devam ettiği görülmüştür. Bu makalenin amacı geçmişten beridir süre gelen tedavi yöntemlerinin o dönemlerde yaşamış ve bu tedavileri deneyimlemiş alimlerin yapmış olduğu çalışmalar doğrultusunda; müzik – sağlık ilişkisi ele alınmış, 800’lü yıllardan itibaren bilim insanlarının, alimlerin müziği sağlık içerisinde nasıl konumlandırdıkları incelenmiştir. Bu bağlamda El-Kındi’nin Ud tellerini çeşitli vücut sıvılarını yükselttiği, İhvan-ı safa topluluğunun El-Kındi’nin çalışmalarından yola çıkarak zararlı vücut sıvılarının azaldığı, Farabi’nin çalışmasında ise müziğin insan psikolojine olan etkilerine yönelik çalışmalar yaptığı görülmüştür. Görüldüğü üzere her bir alim müzikle tedavinin farklı yönlerini ele alarak çalışmalarını sürdürmüştür. Ayrıca çeşitli makamların insan sağlığına etkileri görülmüş ve belirli vakitlerde dinlenilen makamların insan sağlığına faydalı olabileceğine yönelik çalışmaların varlığı tespit edilmiştir. Bu çalışmalar bağlamında elde edilen verilere bakıldığında müziğin sosyal yaşam içerisinde kültürel bir olgu olarak görülmesinin yanı sıra tedavi edici bir unsur olabildiği düşünülmüş ve bu tedavi alanlarının üzerinde daha spesifik çalışmalar yaparak tedavilerin etkilerinin görülmesi için çalışmalar yapılması hususunda önem arz etmektedir.

Published: November 2023

The present study aimed to verify the levels of anxiety and depression in people affected by Covid-19. This is a cross-sectional, exploratory, descriptive quantitative research. Data collection took place between October and December 2022 and was carried out online using a sociodemographic questionnaire, the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder Questionnaire (GAD-7). A total of 320 people participated, 71.9% of whom were female, with an average age of 18 and 68 years, 75.6% of whom had an income of up to three minimum wages, 54.1% were single and the majority self-declared as brown (58.4%). Half of the sample had moderate to severe levels of depression (50.6%) and 41.2% of participants had moderate to severe anxiety scores. Women, young adults, people with some comorbidity, who did not work during the pandemic, who did not practice physical and leisure activities and those with a history of drug treatment for mental health were statistically significant and had higher rates of anxiety and depression. It is suggested that other studies be conducted in favor of a more comprehensive statistical analysis, accounting for a larger number of respondents, in addition to a longitudinal follow-up, in order to enable the analysis of the cause-consequence relationship between anxiety/depression and other comorbidities, previous use of medication and sociodemographic variables, as the results of this study pointed out.

Authors: Alckimin-Carvalho Felipe , Chiapetti Nilse , Nichiata Lucia Izumi
Published: November 2023

Understanding the perception of internalized and community homophobia reported by gay men living with HIV is especially important because it contributes to the production of knowledge that can support public health policies aimed at caring for this population doubly exposed to the burden of stigma. The objective of the study was to evaluate internalized homophobia and perceived social oppression by a sample of gay men living with HIV/AIDS and to verify associations between homophobia and sociodemographic variables of the participants. This is a quantitative study with a cross-sectional design. Participants were 138 gay men with HIV, mean age of 36 years. The survey was conducted online, in the second semester of 2022. The Internalized Homophobia Scale and a sociodemographic questionnaire were used. High scores were found both on the subscale of social oppression, which verifies the perceived stigma in the community, and on the internalized homophobia, which refers to the stigma of gay men in relation to homosexuality. More than 93% of the participants believe that society punishes homosexual people, 98.55% that discrimination against homosexual people is still common, 22% do not like to think about their own sexuality and 22% prefer to have anonymous sexual partnerships. A greater perception of homophobia was verified among retirees and unemployed. The alarming scores of internalized and perceived homophobia in the community point to the urgency of intersectoral actions in Brazil aimed at reducing stigma, especially among individuals belonging to key populations, such as those living with HIV.

The application of socio-educational measures in Brazil became possible with the creation and development of the Statute of the Child and Adolescent. The aim of this study was to understand the vulnerabilities, rights violations and lack of social protection that affect adolescents and lead to them committing offenses. The methodology used was based on a qualitative approach, bibliographical and documentary research on platforms such as PEPSIC, SciELO, Redalyc and Google Scholar, as well as websites, booklets and Brazilian government documents. Descriptors such as adolescent, public policy, defense of children and adolescents were used. Ten articles on the subject were selected. The data was analyzed using content analysis and the theoretical-methodological framework of historical-dialectical materialism. Even though there have been a few historical changes, the outlook, as set out in the National Socio-Educational Care System, that attention should be paid to guaranteeing the rights of adolescents under socio-educational measures, public policies, social protection, and the development of the intersectoral network, are the major challenges to be overcome. The work/research that has been carried out has shown that the public policies in place to assist adolescents do not fully cover adolescents in socio-educational measures. There is a need to work together with the family, society and the state. Making it clear that the process of adaptation and improvement is extremely important, so that they can be re-socialized in a fair and equal way, with all the rights provided for in the laws.

Responding to the COVID-19 pandemic exposed health care professionals to stressors that can lead to Compassion Fatigue. This Integrative Review aimed to analyze the scientific evidences on Compassion Fatigue in health professionals working in the health crisis. Online searches were carried out on the PsycNET platforms and CAPES portal between November 2020 and January 2021. Nine articles met the eligibility criteria and were included in the qualitative analysis. Despite the small number of studies found, it was observed that Compassion Fatigue negatively impacts the caregiver's health, particularly when associated with other conditions such as moral damage, anxiety, depression, sleep disorders, and burnout. It is important to highlight that the design of the studies in question limited the causal determination of the pandemic on these findings. Longitudinal studies with mixed methods are recommended, in addition research on this topic is required in countries that have faced the most devastating pandemic waves, such as Brazil.
Institutional investors and corporate risk at the origin of the international financial crisis
Authors: Lizarzaburu Edmundo , García-Gómez Conrado Diego , Kostyuk Alexander
Published: November 2023

The 2007 financial crisis served as a stark reminder of the vulnerability in the relationship between institutions and companies, as it revealed that many companies collapsed despite government interventions. Two crucial factors that influenced the crisis’s impact on firms were the level of creditor rights protection and corporate risk management. In this study, our aim was to investigate the impact of investment funds and banks on corporate risk prior to the 2007 financial crisis. We conducted an analysis across 21 countries to examine how institutional factors determined the influence of mutual funds and banks on corporate risk, ultimately leading to critical levels of collapse and the global spread of the financial crisis to the real economy. Additionally, we explored the role of mutual funds and banks as reference shareholders. The findings of our study reveal that the process of financial deregulation preceding the 2007 financial crisis contributed to an increase in corporate risk. In other words, financial deregulation facilitated greater involvement of institutional investors in companies, thereby encouraging the adoption of excessively risky and speculative strategies that were not necessarily aligned with the long-term sustainability of firms.

Authors: Zujovic Masa , Milosevic Jelena
Published: November 2023

The interest in pattern geometry and its application to architecture may be seen throughout history. While some authors were fascinated by pattern aesthetics, others were focused on their effectiveness and underlying principles of pattern formation. In continuing with the work of the second group of authors, this paper reviews opportunities for efficient ways of implementing patterns in the design of architectural elements, supported by recent developments in parametric design and digital fabrication techniques. This paper aims to analyze pattern configurations found in nature in order to determine the underlying generation principles and the potential of their application for 3D printed slab systems. Using case study methodology, selected patterns will be applied in developing a generative parametric design system, which will further be tested in creating and (small-scale) fabricating ribbed slab elements. The result of the research is the generalization of a design approach based on principles of natural pattern formation to produce sustainable design solutions that rely on the transposition of the inherent efficiency of natural systems, such as low energy or material consumption.

Published: November 2023

For the purpose of building a new electric power facility a project to determine seismic potential and seismic parameters for design is produced. Multiple in-situ geophysical investigations have been performed and soil samples have been taken to the laboratory where simple shear tests are done to determine the dynamic parameters of the soil layers. As a result, the dynamic shear modulus and damping ratio vs shear strain relationships of characteristic soil materials were defined. The response analysis was done using these curves, where the effects of the sub-surface local soil medium have a dominant influence upon the amplitude and frequency modification of the expected ground motion. Finally, the seismic design parameters, maximum accelerations at foundation level for design and maximum earthquake site-specific response spectrum have been obtained.
Large deformation theory in geomechanics - influence of kinematic nonlinearity on the results of some characteristic geotechnical calculations
Authors: Miladinovic Borko
Published: November 2023

The geotechnical engineering calculations are usually carried out according to the small deformation and displacement theory (infinitesimal strain theory) i.e. firstorder theory. A linear relationship between componental displacements and deformations is adopted. The well-known conditions for equilibrium are defined for an undeformed system i.e. undeformed structure. Therefore, the geometric and static linearity assumptions are usually valid in geotechnical engineering calculations. These linearities are collectively referred to as kinematic linearity. In other words, engineers believe that results of quite satisfactory accuracy are obtained if only material nonlinearity is taken into account in the engineering calculations, regardless of the type of geotechnical problem being analysed. Therefore, it is not necessary to apply the large (finite) deformation theory with the assumption of material nonlinearity. The main aim of this paper is to verify the previous statement in the case of some characteristic problems of Geotechnics. In the first part of this paper, the large deformation theory, which is mostly unknown to the wider professional public, is briefly presented. After that, simple numerical analyses of some characteristic problems of Geotechnics were carried out in the well-known software FLAC 2D software with the aim of comparing the results obtained for the cases of kinematic linearity and kinematic nonlinearity. The obtained results point to the fact that kinematic nonlinearity should not always be ignored in the usual geotechnical engineering calculations. Therefore, engineers are urged to be careful.

Published: November 2023

The requirements of the modern (high-end) construction industry demand the development of new types of concrete of high, and especially very high strength and with significantly improved properties in terms of durability. They provide new possibilities in the field of concrete technology of high strength and performance. When designing the composition of high-strength concrete (HSC), a special attention should be paid to the particle size distribution of aggregates, which should be chosen so as to achieve an "optimal" packing of the aggregate grains. The maximum grain size has been reduced to 2 mm. The Funk-Dinger formula was used to calculate the particle size distribution, which also takes into account fine particles of mineral powder additives. CEM I 52.5R, pure quartz sand, quartz filler, silica fume, powerful superplasticizer and low water/binder ratio were chosen for making HSC. In total, five different concrete mixtures were made. The paper presents the results of testing important properties of hardened concrete at ages from 1 day to 90 days and statistical processing of the obtained test results.

Published: November 2023

Timber-concrete composite (TCC) systems have application for new floors and for upgrading and enhancing of existing timber floors in residential and office buildings. In order to develop the optimal maintenance programs of structures, it is essential to predict the performance of structures over their life-cycle. The long-term behavior of timber-concrete composite floors is influenced by a combination of various factors, including material properties, load distribution, moisture effects, temperature effects and durability considerations. Timber and concrete material in the composite system, exhibit different behaviors over time due to their inherent characteristics. Deterioration prediction models are used to estimate the future degradation and condition of various types of structures. The aim of this paper is to present two probabilistic models, random variable deterioration rate model and stochastic gamma process model, that will capture uncertainty and variability associated with the deterioration of TCC floor under the service load and to estimate its service life.

The lungs are a vital organ in the human body. If there is interference with lung function, the health of the human body as a whole can be affected. Examination by medical workers needs to be done when there is interference with lung function. This examination can usually be done in various ways, one of which is through a chest X-ray radiographic examination procedure. The application of Artificial Intelligence is growing rapidly in the medical field, especially in diagnostics and treatment management. Artificial intelligence in the medical world can also be applied in processing image data in radiology to analyze X-ray results as supporting diagnostic information. Operators Chan-Vese and Canny are two edge detection operators in digital image processing in an effort to obtain the necessary information based on the shape and size of the object. This study was conducted for clustering of normal and tuberculosis lung conditions based on the results of chest X-ray image segmentation from Chan-Vese and Canny using K-Means Clustering. The results of clustering using K-Means obtained an accuracy value of 77.1%, a precision value of 88%, and a specificity value of 97.2%
Watermarking Study on The Vector Map
Authors: Tantriawan Hartanto , Munir Rinaldi
Published: November 2023

In addition to being employed in a variety of military and security applications, GIS vector maps are frequently used in social, environmental, and economic applications like navigation, business planning, infrastructure & utility allocation, and disaster management. Given the high value of this map, copyright protection is implemented in the watermarking as a required safeguard against unauthorized modification and exchange of GIS vector maps. Watermarking is inserting information (watermark) stating ownership of multimedia data. This paper discusses several approaches that can be used to watermark vector maps, including using the space-domain algorithm and transform-domain algorithm. Second The watermarking algorithm was developed with the following quality metrics: fidelity, robustness, capacity, complexity, and security. The challenge in this study is that the higher the capacity, the lower the fidelity value. Low fidelity causes map properties to be lost, making the map unusable. These two things need to be balanced.
Sentiment Analysis and Topic Modelling on Crowdsourced Data
Authors: Siallagan Maria Angelika H , Wijayanto Arie Wahyu
Published: November 2023

Data analysis plays a crucial role in enhancing the decision-making process by uncovering concealed patterns within the data. One valuable form of crowdsourced data is user reviews on applications, which can effectively capture the satisfaction levels of application users. Application developers can utilize these reviews to identify and assess areas of the application that require evaluation or improvement. This study focuses on the classification of application reviews by utilizing sentiment analysis and employs various classification algorithms, including logistic regression, Support Vector Machines, and Random Forest. Additionally, to address negative sentiment labels, topic modeling is conducted using Latent Dirichlet Allocation (LDA). This study demonstrates that the best sentiment classification model is logistic regression, achieving an average accuracy of 0.925 and an average F1-score of 0.763. Furthermore, the LDA analysis successfully generates topic models for negative reviews, revealing three key topics: price-related issues, accessibility concerns, and application accuracy, all of which demand reevaluation and potential improvement

Authors: Sriatna Diah Adi , Andrian Rico , Safei Rahmat
Published: November 2023

Crown density and transparency are among the parameters in determining forest health using magic card. This is still less effective because it only relies on direct vision. Therefore, a more sophisticated and accurate application using digital image technology is needed. Convolutional Neural Network (CNN) is designed to help recognize objects in images with various positions. There are 1000 images of needle leaf types with ten classes of crown density and transparency for every kind of needle leaf, including araucaria heterophylla, cupressus retusa, pine merkusii, and shorea javanica, which are classified using AlexNet. AlexNet is a CNN architecture that has eight feature extraction layers. The AlexNet model succeeded in classifying coniferous trees on the scale of density and crown transparency with an accuracy level of 87.00% for araucaria heterophylla, cupressus retusa 96.00%, merkusii pine 86.00%, and shorea javanica 95.00%. Although some errors were still found in classification, this was caused by similar patterns and similar image positions. It is hoped that the results of this research will be used in monitoring forest health in the future.
