Published: March 2022

Central Processing Unit (CPU) and External Graphics Processing Unit (eGPU) technology are known as overclocks which aim to make the device exceed the benchmarks set by the device maker. Until now there is no determination to rank the two hardware within certain limits such as hardware price range and year-by-year. Therefore, it is necessary to process the ranking of the hardware using Simple Additive Weighting (SAW) to obtain a ranking range and determine the weight per type of hardware analyzed. It can be classified using Naïve Bayes to determine results of criteria combination between two hardware to determine possible criteria into "not good" and "good". This classification used to determine probability criteria of choosing a combination of CPU and eGPU hardware. The results of this study are getting the best CPU and eGPU every year using SAW and then classifying it for pricing. In testing conducted on application of Naïve Bayes using 80% of training data has 2776 data and 20% of testing data has 695 data that will be tested for accuracy, precision, recall, and F1-score. For results of tests that have been carried out get 0.78 accuracy results, precision 1, Recall 0.764, and F1-Score 0.866.

Published: March 2022

Sentiment analysis is part of computational research that extracts textual data to obtain positive, or negative values related to a topic. In recent research, data are commonly acquired from social media, including Twitter, where users often provide their personal opinion about a particular subject. Energy independence was once a trending topic discussed in Indonesia, as the opinions are diverse, pros and cons, making it interesting to be analyzed. Deep learning is a branch of machine learning consisting of hidden layers of neural networks by applying non-linear transformations and high-level model abstractions in large databases. The recurrent neural network (RNN) is a deep learning method that processes data repeatedly, primarily suitable for handwriting, multi-word data, or voice recognition. This study compares three algorithms: Simple Neural Network, Bernoulli Naive Bayes, and Long Short-Term Memory (LSTM) in sentiment analysis using the energy independence data from Twitter. Based on the results, the Simple Recurrent Neural Network shows the best performance with an accuracy value of 78% compared to Bernoulli Naive Bayes value of 67% and LSTM with an accuracy value of 75%. Keywords— Sentiment Analysis; Simple RNN; LSTM; Bernoulli Naive Bayes; Energy Independence;

Published: March 2022

The continuous growth of the internet has led to the use of social media for various purposes increase. For instance, some irresponsible parties take advantage of the comment feature on social media platforms to harm others by providing spam comments on the shared object. Furthermore, variation of comments creates many features to be processed, thereby negatively impacting the performance of a classification algorithm. Therefore, this study aims to solve the problem associated with spam comments by comparing filter and wrapper based feature selection using text classification techniques. Data collected from training and test data of 4944 and 100 comments showed that the best accuracy, precision, recall, and f-measure of MNB are 96%, 100%, 92%, and 95.8%. The best accuracy is achieved using feature selection by combining Chi-Square and Sequential Forward Selection methods with a subset of 500 features. Furthermore, the accuracy increase in the MNB and SVM classifications are 8% and 4%. This research concludes that the combination of feature selection improves the classification performance of Indonesian language spam comments.

The process of selecting from many alternatives to the criteria is a decision that is often determined in decision making. The criteria for which criteria can consist of many attributes are used by decision-makers in making the selection or are called multi-criteria decision making (MADM ). Determining the Artist Music Festival at an event has quite a complicated difficulty, because the assessment of the criteria is heterogeneous. The spider web's approach to integrating criteria results in the selection of the artist form that attracts the most attention, and public interest. Model AHP use of multi-attributes is used in selecting artists to perform at music festivals, selecting artists using criteria, namely Number of Followers (C1), stamp C2, Average Popular Tracks (C3), Average Youtube Viewers (C4), and the price of the artist (C5). Data on the number of followers, popularity, average popular tracks, and average YouTube viewers were obtained using the Spotify and Youtube APIs. The settlement method applied is the Analytical Hierarchy Process (AHP) and the Rating Scale algorithm, with an alternative using five samples of Indonesian artists. The research results are expected to provide recommendations for artists as performers in the music festival.

Published: March 2022

Background: Allergic rhinitis (AR) is a major non-communicable
disease that affects the health-related quality of life (HRQoL) of
patients. AR is significantly related to asthma also affecting HRQoL.
However, data on HRQoL and symptom control in AR patients with comorbid
asthma are lacking. Objective: To assess the differences of
symptom control and HRQoL in AR patients with and without comorbid
asthma. Methods: In this multicentre, cross-sectional study,
patients with AR were screened and administered questionnaires of
demographic characteristics and health conditions (symptoms/diagnosis of
AR and asthma, disease severity level, and allergic conditions). HRQoL
was assessed using a modified version of the RHINASTHMA questionnaire
and symptom control was evaluated by a modified version of the Control
of Allergic Rhinitis/Asthma Test (CARAT). Results: Out of 643
patients with AR, 500 (78%) had asthma as a comorbidity, and 54% had
moderate-severe intermittent AR, followed by moderate-severe persistent
AR (34%). Patients with both AR and asthma had significantly higher
RHINASTHMA scores than the patients with AR alone (e.g., median
RHINASTHMA-total score 84 vs. 48.5, respectively). Conversely, CARAT
scores were significantly lower in AR with comorbid asthma than in the
patients with AR alone (median CARAT-total score 16.5 vs. 23,
respectively). Upon stratifying asthma based on severity, AR patients
with severe persistent asthma had worse HRQoL and control than AR
patients with mild persistent asthma. Conclusions: Our
observation of poorer HRQoL and symptoms control in AR patients with
comorbid asthma supports the importance of a comprehensive approach for
the management of AR in case of a comorbid allergic condition.

Published: March 2022

Microbial fuel cell (MFC) is a hybrid technology that produces electricity and recovers resources from wastewater through biocatalytic and electrochemical reactions. Metallurgical facilities in Bor, Serbia, are a source of copper-rich metallurgical wastewater, and the Town of Bor is a source of municipal wastewater rich in organic matter. The aim of this paper is to investigate the possibility of application of MFC for the treatment of metallurgical and municipal wastewater that are released into the Bor River in Serbia. A prototype of MFC was constructed for this study, and 3 sets of experiments were performed using model solutions and real wastewater. Copper was successfully removed from the treated model solution with 99.42 % efficiency. Solid copper particles were obtained with a particle size of about 1 ?m. Maximum chemical oxygen demand (COD) removal rate of 191.7 mg L-1 h-1 was observed in the anodic compartment. The impact of this study is significant because MFC was implemented for the simultaneous treatment of two types of wastewaters, one containing metals and the other containing organic matter, and both types of wastewater are released into the same river.

Authors: Chan Kam Suen , Wan Eric Yuk Fai , Chin Weng Yee , Yu Esther Yee Tak , Mak Ivy Lynn , Cheng Will Ho Gi , Ho Margaret Kay , Lam Cindy Lo Kuen
Published: March 2022

Background

Cardiovascular diseases (CVD) are a long-term
sequela of diabetes mellitus. Better individual-based continuity of care has
been reported to reduce the risk of chronic complications among patients with diabetes
mellitus. Maintaining a one-to-one patient-physician relationship is often challenging,
especially in public healthcare settings. This study aimed to evaluate the relationship
between higher team-based continuity of care, defined as consultations provided
by the same physician team, and CVD risks in patients with diabetes mellitus from
public primary care clinics.

Study
design

This was a retrospective cohort study in
Hong Kong of 312,068 patients with type 2 diabetes mellitus and without any history
of CVD at baseline (defined as the earliest attendance at a doctor’s
consultation in a public-sector clinic between 2008-2018). Team-based continuity
of care was measured using the usual provider continuity index (UPCI), calculated
by the proportion of consultations provided by the most visited physician team in
the two years before baseline. Patients were divided into quartiles based on their
UPCI, and the characteristics of the quartiles were balanced using propensity
fine stratification weightings. Multivariable Cox regression was applied to
assess the effect of team-based continuity of care on CVD incidence. Patient
demographics, smoking status, physiological measurements, number of
attendances, comorbidities, and medications were adjusted for in the propensity
weightings and regression analyses.

Result

After an average follow-up of 6.5 years,
the total number of new CVD events was 52,428. Compared to patients in the 1st
quartile, patients in the 2nd, 3rd and 4th quartiles
of the UCPI had a CVD hazard ratio (HR) (95% confidence intervals) of 0.95 (0.92-0.97);
0.92 (0.89-0.94) and 0.87 (0.84-0.89) respectively, indicating that higher continuity
of care was associated with lower CVD risks. The subtypes of CVD, including
coronary heart disease and stroke, also showed a similar pattern. Subgroup analyses
suggested that patients younger than 65 years had greater benefits from higher team-based
continuity of care.

Conclusion

Team-based continuity of care was
associated with lower CVD risk among individuals with type 2 diabetes mellitus,
especially those that were younger. This suggests a potential flexible
alternative implementation of continuity of care in public clinics.
Investigation of Performance on Photovoltaic/Thermal (PV/T) System Using Magnetic Nanofluids
Authors: SWESE Ettahır  El Hadı Alı Omar , HANÇERLİOĞULLARI Aybaba
Published: March 2022

Photovoltaic/Thermal (PV/T) systems provide hot fluid (usually water) production as well as electrical energy production. In addition, since the overheating of the PV systems is prevented by the heat drawn by the thermal system, the electricity production performance of the PVs increases. Nanofluids are offered as a solution to increase the heat absorbed in the thermal system. The main physical events that lead to a significant improvement in the heat transfer performance of nanofluids can be summarized as follows: (i) The thermal conductivity of the prepared nanofluid increases at certain rates because the thermal conductivity of the solid metal is higher than that of the basic fluid, (ii) The heat transfer surface area increases due to the increase in the thermal conductivity of the fluid, (iii) Increase in the effective thermal capacity of the fluid, (iv) Increase in the thermal conductivity of the fluid and turbulent volume due to high fluid activity. In this study, by using nanofluids obtained by adding 1% Fe2O3, Fe3O4 and NiFe2O4 magnetic nanoparticles by weight to the basic fluid water, a bidirectional performance increase was achieved by increasing the thermal heat transfer of the PV/T system while providing more cooling of the PV system. In the experimental study, a 14% improvement in electricity production was achieved in NiFe2O4 nanofluid by drawing more heat from the heated PV panels by utilizing the high thermal conductivity of nanofluids. Since the amount of heat absorbed in the thermal system is high, an average of 104% temperature (∆T) increase in the hot fluid temperature compared to the base fluid water was obtained in the NiFe2O4 nanofluid.
Introduksjon: Pedagogikk under press. Hvordan kan vi motstå presset?

This introduction takes a closer look at the six contributions in this special issue, i.e., contributions from Germany, Denmark, Norway, Sweden, Finland and Scotland. We make use of these six articles as empirical material to examine what we refer to as external, internal and invisible pressures on pedagogy. The introduction thus conducts a meta-discussion, or a discussion of the discussions that take place in the six articles. A consistent finding that emerges in the special issue is that pedagogy in the six countries is exposed to different kinds of pressure, which, we argue, will lead to unfortunate consequences. Finally, we discuss how it may be possible to resist the pressure on pedagogy and at the same time strengthen pedagogy as a subject and an academic discipline.

Published: March 2022

Introduction. The article presents an analysis of accidents of lifting cranes, the causes of which are the destruction of load-bearing structural connections during the designated service life, caused by structural and technological deficiencies, with operational loads not exceeding the passport specifications.

Problem Statement. The objective of the study is to analyze the causes of accidents of different types of lifting cranes and the features that connect these accidents.

Theoretical Part. A review of statistical data on accidents on lifting cranes has shown that the destruction of load bearing structures occurs not only due to fatigue strength during long-term operation, but also due to insufficient bearing capacity of the hinge joints, violations of technological processes of structural elements welding in conditions not exceeding the passport specifications during the service life.

Conclusions. It is established that the destruction occurs in the design elements of metal structures associated with the crane mounting at a relatively high level of operating stresses and insignificant loading cycles, which indicates errors in the design and violations of welding processes during their manufacture.

Authors: Lanani Karman
Published: March 2022

Kecemasan merupakan keadaan emosi yang tidak menyenangkan, dicirikan dengan kegelisahan, ketidakenakan, kekhawatiran, ketakutan yang tidak mendasar tentang terjadi hal-hal yang tidak diinginkan ketika menghadapi pembelajaran matematika. Terdapat empat faktor penyebab kecemasan siswa terhadap matematika, yaitu: (1) sebagai cabang ilmu yang spesifik, obyeknya fakta, konsep, operasi dan prinsip yang berperan dalam membentuk proses berpikir matematis dibutuhkan kompetensi untuk mempelajarinya, (2) persepsi dimasyarakat bahwa matematika itu sulit telah mengkoptasi pikiran sebagian anak, (3). Pembelajaran matematika yang “kering”, monoton dan guru yang cenderung represif, dan (4) tuntutan  mendapat nilai baik dari orang tua dan guru. Pembelajaran kooperatif sebagai pendekatan yang dirancang untuk memberi dorongan kepada siswa agar bekerjasama selama proses pembelajaran, saling menghargai pendapat, membetulkan kesalahan dan memecahkan solusi secara bersama. Kolaborasi sedemikian akan menambah pengetahuan dan keterampilan siswa memecahkan  masalah dalam matematika.
