Authors: Setiaji Galet Guntoro , Suntoro Joko , Rifa'i Ahmad
Published: May 2024

Algoritme Random Forest (RF) sangat populer digunakan pada metode klasifikasi karena waktu learning yang cepat, mampu melakukan pembobotan pada variabel, dan kinerja yang sangat baik pada dataset berukuruan besar, namun algoritme RF mempunyai performa yang buruk saat menangani data dengan kelas tidak seimbang. Data dengan kelas tidak seimbang adalah jumlah data pada kelas tertentu lebih banyak dibandingkan dengan jumlah data pada kelas lainnya. Undersampling (US-RF) adalah salah satu metode yang digunakan untuk penanganan data dengan kelas tidak seimbang, namun metode undersampling akan memilih dan mereduksi data secara acak pada kelas mayoritas sehingga berakibat hilangnya data yang berpotensi berguna. Untuk menghindari hilangnya data yang berpotensi berguna tersebut karena dipilih secara acak, maka akan diterapkan penetapan nilai random state pada metode undersampling. Metode yang diusulkan diberi nama random state parameter undersampling Random Forest (RSUS-RF). Dalam penelitian ini akan dibandingkan antara metode RF, US-RF dan RSUS-RF. Hasil penelitian menunjukkan nilai rata-rata akurasi metode RSUS-RF lebih tinggi dibandingkan dengan metode RF dan US-RF dengan nilai rata-rata akurasi metode RSUS-RF sebesar 0.8259, sedangkan nilai rata-rata akurasi metode RF dan metode US-RF sebesar 0.8035 dan 0.7945. Serta terdapat perbedaan secara signifikan diantara ketiga metode tersebut ketika diuji menggunakan Friedman Test dengan nilai p-value adalah 0.005.

Psychological Support for People with Hard of Hearing, Acquired Hearing Loss, and Auditory Processing Disorders — A Secondary Publication
Authors: Katsuya Noriko
Published: May 2024

This paper discusses the psychological support available for hard of hearing and acquired hearing loss difficulties. Specifically, it shows the psychological support that has been available to people with hard of hearing and listening problems, including those who became hard of hearing after acquiring language, those with mild to moderate hearing loss, those with unilateral hearing loss, those with an auditory processing disorder, and those who do not have a physical disability certificate. This paper also proposes support for people who have hitherto been unlikely to access such support and describes the current status of efforts to make support available in Japan. This paper covers the psychological support provided by specialists, by people who are close to the individuals in question but are not specialists, and by other people who are hard of hearing. Support by people with hearing loss can be divided into three types: self-help groups, meetings for people with hearing loss, and “Tojisha-Kenkyu,” groups that research self-support. Each of these forms of psychological support is described, and the current status and the barriers to the provision of support by people who are hard of hearing are described in detail. As future tasks, the author notes the tasks of how to maintain the cohesion of the various groups, empirical research on the effects of psychological support, and the need to raise greater awareness and disseminate information about hard-of-hearing people’s meetings that engage in psychological support activities.

Authors: Gharbi O. , Boujelbène M. , Zouari R.
Published: May 2024

The main purpose of this paper is to test the performance of GARCH models in estimating and forecasting VaR (value at risk) of the US Fintech stock market from July 20, 2016, to December 31, 2021. In addition, this study examines the impact of COVID‑19 on the risk spillover between the adequate VaR series of the US global KFTX index and the five Fintech industries. Specifically, we compare different VaR estimates (862 in‑sample daily returns) and predictions (550 out‑of‑sample daily returns) of several GARCH model specifications under a normal and Student‑t distribution with 1% and 5% significance. The Backtesting results indicate that I‑GARCH with Student‑t distribution is a good model for estimating and forecasting VaR of the US Fintech stock market before and during COVID-19. Moreover, the total connectedness results suggest that global and each Fintech industry increases significantly under turbulent market conditions. Given these considerations, this paper provides policymakers and regulators with a better understanding of risk in the Fintech industry without inhibiting innovation.

Authors: Xavier Renata Lucon , Menezes Denise Balestrero , Da Silva Fábio Leandro
Published: May 2024

O processamento automatizado dos dados da plataforma MapBiomas tem sido amplamente utilizado para o mapeamento do uso e cobertura do solo. No entanto, podem ocorrer confusões devido à escala temporal e à diversificação das atividades de ocupação. Nesse contexto, este trabalho teve como objetivo apresentar uma abordagem manual para aumentar a precisão das classes de uso e cobertura do solo no município de Meridiano. A abordagem adotada consistiu na correção e inserção de novas camadas utilizando imagens dos satélites Google Earth Pro e RapidEye, que foram posteriormente verificadas por validação terrestre. Os resultados revelaram melhorias significativas, especialmente na classificação de áreas inicialmente identificadas como mosaico de agricultura e pastagem, que totalizavam 4907 hectares. Após as correções, essas áreas foram distribuídas entre as culturas de cana-de-açúcar, citrus e vegetações campestres. Além disso, houve um aumento significativo na classe de silvicultura, que anteriormente havia sido confundida com formações florestais devido à predominância de heveicultura já de porte alto. A precisão obtida na caracterização do uso e ocupação do solo forneceu informações valiosas sobre a utilização da terra e as atividades econômicas predominantes, contribuindo para a compreensão e monitoramento das mudanças ambientais. Embora a metodologia tenha se mostrado adequada e de fácil aplicação, é importante ressaltar que pode ser limitada em áreas maiores devido à necessidade de procedimentos manuais extensos e detalhados. Por fim, destaca-se a relevância da utilização da Coleção 6 do MapBiomas neste estudo, que proporcionou uma base consistente e atualizada para o mapeamento do uso e cobertura do solo.
Análise dos agentes, insumos e processos ligados a estação de tratamento de efluentes por tanque séptico seguido de wetland construído para comunidades rurais
Authors: Silva Aline de Souza , Oliveira Adna Caroline Vale , Spinola Carolina de Andrade , Moreira Ícaro Thiago Andrade
Published: May 2024

Os dados da literatura evidenciam a precariedade do acesso aos serviços de saneamento básico, sobretudo em relação ao esgotamento sanitário. Quase a metade da população rural brasileira lança seus efluentes através das fossas rudimentares, que contaminam o ambiente e geram problemas de saúde pública. Uma alternativa para minimizar os impactos negativos da disposição de águas residuárias sem tratamento prévio é a utilização da estação de tratamento de efluentes (ETE) por tanque séptico seguido de wetland construído (TS+WC). O principal objetivo deste trabalho é se debruçar sobre os custos e possíveis gargalos associados à implantação, operação e manutenção da ETE por TS+WC para comunidades rurais, bem como os aspectos legais e normativos associados ao provimento do serviço de esgotamento sanitário rural descentralizado no Brasil. Para tanto, foi realizada uma revisão de literatura baseada através da pesquisa exploratória sobre a ETE descentralizada por TS+WC em cluster sob as variáveis: funcionamento, características das comunidades, arranjos institucionais de implementação, aspectos legais e normativos, custos e financiamento. O presente estudo evidencia que, embora a ETE por TS+WC seja uma solução de baixo custo, é preciso considerar os gargalos associados ao provimento do serviço, além da necessidade de políticas públicas e discutir sobre aspectos regulatórios voltados para a expansão das ETEs descentralizadas e eficientes.

Authors:   Koreanisch-Deutsche Gesellschaft Fuer Erziehungswissenschaft, Yoon Dohye
Published: May 2024

The purpose of this study is to identify the meaning of informal learning for adult learners in lifelong learning by reviewing discourses in pedagogy related to informal learning and introducing heuristic model for practical research on informal learning. To this end, after reviewing the main perspectives on the meaning of informal learning, which has been conventionally discussed in educational research, in detail, the trends in informal learning research in three areas primarily observed in lifelong learning (informal learning in the workplace, multicultural informal learning, and community informal learning) were examined. Adult learners’ informal learning occurs through interactions between society, culture, media, or members in the everyday learning environment based on sociocultural context to which they belong, such as society, community, and workplace. Based on this, a heuristic model of informal learning was introduced that takes into account the social conditions of learners that can produce continuous informal learning as well as individual learner aspect. In the end, as a comprehensive perspective to understand human learning in the further research, the research direction for informal learning research and the expectation for the analytical foundation of practical research to support adult learners' informal learning was suggested.

Authors: Almuashi Hanan
Published: May 2024

In this article, we discuss a mathematical system modelling Chikungunya virus dynamics in a seasonal environment with general incidence rates. We establish the existence, uniqueness, positivity and boundedness of a periodic orbit. We show that the global dynamics is determined using the basic reproduction number denoted by R0 and calculated using the spectral radius of a linear integral operator. We show the global stability of the disease free periodic solution if R0<1 and we show also the persistence of the disease if R0>1 where the trajectories converge to a periodic orbit. Finally, we display some numerical examples confirming the theoretical findings.

The aim of this study was the Longitudinal Study of Change in CD4+ Cell Counts on HIV-Positive Patients at Dalhatu Araf Specialist Hospital, Lafia. The study deployed linear mixed effects models to check if the mean response CD4+ cell count varies with time. The study also attempted to test if the mean response varies in the two groups. An attempt to estimate the relationship between the response and observations according to gender. The study revealed that the trajectory of the mean response over time has a very high variability where we see that there is a general rise in the CD4+ cell counts at the initiation of ART. It was further seen that the CD4+ cell counts in male patients is observed to be higher with higher median value after the sixth observation. A linear mixed effect model was used and tested where it was noted that there is evidence of between-individual heterogeneity which further shows that the decision to choose a mixed effects model instead of an only fixed effects model was in order. The model summary showed that the mean CD4+ cell counts at the baseline (OBS1) was averagely good, but at the initiation of ART, there was a significant increase in the mean response where it was further revealed that the pattern of the mean response over time is not flat. In modelling the group effects, we see the difference between the mean CD4 cell count of male versus female is -113.62 CD4 cell count (i. e. 95% CI= -290.64 to 63.39) lower than female, adjusting with time. Finally, the Wald test does not show any significant evidence of interaction between the observations and gender (p=0.2925) which suggests that the mean response based on gender may be parallel.

Twitter is a social media platform that is very important in the digital world. Fast communication and interaction make Twitter a vital information center in sentiment analysis. The purpose of this research is to classify public opinion about the presence of marketplaces in Indonesia, both positive and negative sentiments, using a Non-linear SVM algorithm based on 1276 tweets. This research involves the stages of data pre-processing, labeling, feature extraction using TF-IDF, and data division into three scenarios: 80% training data and 20% test data, 50% training data and 50% test data scenario, and 20% training data and 80% test data scenario. The last process, GridSearchCV, combines cross-validation and non-linear SVM parameters for model evaluation using a confusion matrix. The best SVM model resulting from the scenario was 80% training and 20% test data, with hyperparameters Gamma = 100 and C = 0.01, achieving 89% accuracy. When tested on never-before-seen data, the accuracy increased to 90%, with an f1-score of 91%, precision of 88%, and recall of 95% on negative sentiments. In conclusion, evaluating the performance of non-linear SVM kernels with a combination of hyperparameter values can improve accuracy, especially on public response information about online marketplaces and public sentiment.
Optimization of Hyperparameter K in K-Nearest Neighbor Using Particle Swarm Optimization
Authors: Rizki Muhammad , Hermawan Arief , Avianto Donny
Published: May 2024

This study aims to enhance the performance of the K-Nearest Neighbors (KNN) algorithm by optimizing the hyperparameter K using the Particle Swarm Optimization (PSO) algorithm. In contrast to prior research, which typically focuses on a single dataset, this study seeks to demonstrate that PSO can effectively optimize KNN hyperparameters across diverse datasets. Three datasets from different domains are utilized: Iris, Wine, and Breast Cancer, each featuring distinct classification types and classes. Furthermore, this research endeavors to establish that PSO can operate optimally with both Manhattan and Euclidean distance metrics. Prior to optimization, experiments with default K values (3, 5, and 7) were conducted to observe KNN behavior on each dataset. Initial results reveal stable accuracy in the iris dataset, while the wine and breast cancer datasets exhibit a decrease in accuracy at K=3, attributed to attribute complexity. The hyperparameter K optimization process with PSO yields a significant increase in accuracy, particularly in the wine dataset, where accuracy improves by 6.28% with the Manhattan matrix. The enhanced accuracy in the optimized KNN algorithm demonstrates the effectiveness of PSO in overcoming KNN constraints. Although the accuracy increase for the iris dataset is not as pronounced, this research provides insight that optimizing the hyperparameter K can yield positive results, even for datasets with initially good performance. A recommendation for future research is to conduct similar experiments with different algorithms, such as Support Vector Machine or Random Forest, to further evaluate PSO's ability to optimize the iris, wine, and breast cancer datasets.

Authors: Aguilar Rocha Irving Samadhi , Huerta Morales María Guadalupe
Published: May 2024

Esta obra sobre interculturalidad y diversidades parte de un contexto universal, es decir, se enmarca en los procesos de globalización del presente siglo XXI. Uno de los debates sostenidos al interior del campo filosófico y de las ciencias sociales, se concentra en las formas de construir un diálogo intercultural capaz de superar fundamentalismos políticos, ideológicos, étnicos y religiosos. Las perspectivas para abordar el tema son diversas y se plantean desde problemáticas diferentes; por ejemplo, la reproducción de diferentes prácticas socioculturales a distintas escalas, la organización de las actividades contemporáneas comunes a todos, las interacciones entre distintos actores y países. En todas ellas, la interculturalidad, entendida como un diálogo, implica relaciones conflictivas. Los conflictos, desde diferentes enfoques, producen cambios sociales y, además, se interiorizan a nivel emocional. Este libro pone en evidencia, a través de las diferentes investigaciones aquí reunidas, las situaciones de opresión y resistencia histórica, cultural y socioeconómica existentes en las sociedades. El carácter de las propuestas es crítico, debido al acercamiento a diversas posturas teóricas planteadas en contextos problemáticos y por mostrar conflictos de intereses políticos y económicos, individuales y grupales. En este sentido, se parte de marcos teóricos que posibiliten los discursos sobre lo diverso.
The Effects of Unified School Enrollment Systems on School Demographics and Outcomes: Evidence From New Orleans’ Transition to a Centralized School Lottery
Authors: Lincove Jane Arnold , Valant Jon
Published: May 2024

Unified enrollment (UE) systems were designed to improve efficiency, equity, and transparency in school choice processes, but research has focused on efficiency gains. This study examines whether moving from decentralized enrollment processes to UE mitigates or exacerbates racial segregation that often occurs in choice systems. Specifically, we examine a subset of charter schools in New Orleans that had enrolled disproportionately high numbers of White students prior to entering UE. We find that UE entry was associated with increased enrollment of non-White students in these schools without offsetting declines in White enrollment, facilitated by schools also increasing total enrollment after entering UE. We find no meaningful impacts of UE on school accountability measures, student or teacher mobility, or student discipline.

Sağlık meslekleri profesyonelliği gerektirir. Ancak toplum içinde pratik sağlık uygulayıcılarının emeklerini de göz ardı etmemek gerekir. Erkek uygulayıcılar askerlikte kısa süreli enjeksiyon ve pansuman gibi işlemler de eğitilmektedir. Terhis olduktan sonra da bu tip işlemleri gündelik hayatlarında yapabilmektedirler. Yine halk içinde kırık çıkık gibi sağlık sorunlarında başvurulan uygulayıcılar bulunmaktadır. Babam da İzmir Narlıdere Kışlası’nda sıhhiye onbaşısı eğitimi alarak askerliğini Erzurum’da 1959-1960 yılları arasında yapmış. Belleğimde kalan anılarda 3000 nüfuslu Gümüşçay beldemizde Dr. Abdulllah lakaplı Abdullah Amca, İğneci, İbrahim Amca, Babam, Sarı İsmail Amca ve kadın olarak Nazife Teyze halkın enjeksiyon ihtiyacında yanıbaşında idiler. Üstelik benim hatırladığım Şükran Ebe ve sağlık memuru Sıhhiye Ramazan isimli profesyonel sağlık personeli de vardı. Bu kısa yazıda yazarın yaşantıları üzerinden enjektör (şırınganın) şekilsel olarak değişiminden söz edilmektedir. Sağlık hizmetlerinin pratik yaşamda uygulanışı anılar üzerinden aktarılmaya çalışılmıştır. Ayrıca halktan biri olarak yazarın annesinin belleğinde kalan tıbbi terimlere ilişkin söylemleri anlatısal yöntemle aktarılmıştır.

Introduction. Currently, the production of medicines, including those with antimicrobial properties, is expanding at chemical and pharmaceutical enterprises. However, scientific approaches to hygienic regulation of the content of specific antimicrobials in the air of the work area are not yet available.
The study aims to substantiate approaches to predicting approximate safe levels of exposure (ASLE) to substances with a specific antimicrobial effect.
Materials and methods. The scientists have carried out the research in two stages. The first stage is an experimental study of the single inhalation effect of an antibiotic clarithromycin at concentrations of 54.2; 25.4; 15.3; 9.1; 2.8 and 0.9 mg/m3 on mongrel female rats weighing 230–250 g. The authors have evaluated the indicators of toxic (morphological and functional parameters of the nervous, cardiovascular and respiratory systems, biochemical parameters of the liver and kidneys, as well as the composition of peripheral blood) and specific effects (qualitative and quantitative composition of the microbiota of the large intestine of rats).
The second stage was the analysis of the database on hygienic rationing of chemicals, which consisted in searching for hygienic standards (ASLE, MPC), threshold concentrations for the general toxic (Limint) and specific (Limbact) effects of antimicrobials.
Results. During the experiment, experts have established the threshold of acute inhalation exposure (Limac int) of clarithromycin at a concentration of 25.4 mg/m3 according to the total toxic effects (peripheral blood counts, liver and kidney function). When exposed to an antibiotic at a concentration of 2.8 mg/m3, there was an imbalance of the intestinal microflora in the absence of a general toxic effect, which indicated a specific and selective antimicrobial effect of the drug.
Based on the analysis of literature data, the parameters of toxicometry of 21 substances with antimicrobial effect were determined, their representative sample was justified and its regression analysis was carried out.
Conclusion. Based on experimental and literary data, the authors established a significantly strong correlation (r=0.729) between the values of MPC (ASLE) and the threshold of antimicrobial action (Limbact). They also developed a mathematical equation to predict safe levels of antimicrobials based on their specific and selective activity.

Introduction. One of the leading places in the structure of socially significant diseases in the Russian Federation is occupied by malignant neoplasms, among which cancer of the trachea, bronchi and lung occupies the first place in terms of prevalence. Screening for lung cancer is not carried out at the federal level in Russia; recommended screening measures include questionnaires to identify risk factors for the development of the disease (including occupational) and the formation of dispensary observation groups.
The study aims to assess the prognostic value of a new method of biohybrid screening of lung cancer by exhaled air.
Materials and methods. Scientists conducted a study at the National Medical Research Center of Oncology of the Ministry of Health, Russian Federation, with the participation of 24 conditionally healthy volunteers and 5 patients diagnosed with lung cancer in the early stages of the disease. The design of the study is simultaneous (on-line) with blinding; experts estimated the risk of systematic errors at 10 points on the QUADAS scale. The authors examined exhaled air samples on a gas analyzer (biohybrid detector) of the BGS-APK 02SZZ model, in which the sensor were animals — gray domesticated rats (Rattus norvegicus) with microelectrode matrices implanted into the olfactory bulb, and which were in the internal (ventilated) space of the analyzer in a state of drug anesthesia. The conclusion about the presence or absence of a risk of lung cancer was formed by an artificial neural network of the analyzer, at the input of which bioelectric signals from each microelectrode were received, which were preprocessed using a system for recording the focal activity of the olfactory analyzer. The specialists confirmed the presence or absence of a risk of lung cancer by a reference method, according to computed tomography of the chest in accordance with the Lung Imaging Reporting and Data System (LungRADS™).
Results. During the study, experts determined the effectiveness indicators of the method of biohybrid lung cancer screening by exhaled air: sensitivity (64%), specificity (87%), prognosticality of negative and positive conclusions about the presence/absence of disease risk (82% and 72%, respectively).
Conclusion. The safety, efficiency and throughput of the investigated method, together with the reproducibility of the analyzer's conclusions, meet the criteria of practicability to ensure the first (population-based) stage of lung cancer screening.

Introduction. The use of personal protective equipment (PPE) against pathogenic biological agents (PBA) by medical workers in microbiological laboratories is a mandatory requirement for infectious safety, however, low or absent air and vapor permeability of these PPE and their elements can contribute to disruption of the functional and thermal state.
The aim of the study is a physiological and hygienic assessment of PPE against pathogenic pathogens based on indicators of the thermal state of the body when modeling the professional activities of microbiological laboratory workers.
Materials and methods. The study was conducted on the basis of the laboratory of personal protective equipment and industrial exoskeletons of Izmerov Research Institute of Occupational Health on 12 practically healthy individuals — male and female medical workers while simulating work activities and sanitary and epidemiological requirements for a microbiological laboratory.
Results. The values of skin and body temperature, heart rate, blood pressure and blood oxygen saturation levels obtained in the dynamics of the study made it possible to determine the degree of stress in the thermal and functional state of the body of medical workers. The indicators obtained during the experiment were assessed in accordance with current regulatory documents. A number of thermal state indicators obtained during the study had statistically significant differences from their initial values at p<0.05.
Conclusions. When using personal protective equipment against pathogenic pathogens under comfortable microclimatic conditions, an increase in some criterion indicators of the examined individuals was noted, in particular to the upper limit of permissible values of thermal state, which indicates the leading influence of PPE on the thermoregulation of the body and necessitates a reduction in the process of production activities and requires limiting the maximum duration of a work shift under given conditions is three hours, followed by a break to restore the thermal state and water-salt balance.
Ethics. The study was conducted in compliance with ethical principles and norms, an extract from the minutes of the meeting of the local ethics committee No. 9 dated 11/23/2022 was obtained.
