INTRODUCTION: With the continuous progress of the medical Internet of Things, intelligent medical wearable devices are also gradually mature. Among them, medical wearable devices for arrhythmia detection have broad application prospects. Arrhythmia is a common cardiovascular disease. Arrhythmia causes millions of deaths every year and is one of the most noteworthy diseases. Medical mobile information systems (MMIS) provide many ECG signals, which can be used to train deep models to detect arrhythmia automatically.
OBJECTIVES: Using deep models to detect arrhythmia is a research hot spot. However, the current algorithms for arrhythmia detection lack of attention to the unsupervised depth model. And they usually build a large comprehensive model for all users for arrhythmia detection, which has low flexibility and cannot extract personalized features from users. Therefore, this paper proposes a personalized arrhythmia detection system based on attention mechanism called personAD.
METHODS: The personAD contains four modules: (1) Preprocessing module; (2) Training module; (3) Arrhythmia detection module and (4) User registration module. The personAD trains a separate autoencoder for each user to detect personalized arrhythmia. Using autoencoder to detect arrhythmia can avoid the imbalance of training data. The autoencoder combines a convolutional network and two attention mechanisms.
RESULTS: Based on the results on MIT-BIH Arrhythmia Database, we can find that our arrhythmia detection system achieve 98.03% and 99.32% respectively.
CONCLUSION: The personAD can effectively detect arrhythmia in ECG signals. The personAD has higher flexibility, and can easily modify the autoencoders for detecting arrhythmia for users.

Authors: Langgar Dorcas , Bani Marsi , Ly Petrus 
Published: May 2023

This research is motivated by changes in the learning process due to the Covid-19 pandemic where the learning process during the Covid-19 pandemic uses online learning and post-covid-19 learning again uses the face-to-face (offline) learning process, where these two learning processes affect student learning motivation. The purpose of this study is to find out the picture of learning motivation during online learning, offline learning and comparing student learning motivation during online learning and offline learning. This research was conducted on students of Citra Bangsa Kupang Junior High School using a causal-comparative type of research. This research is an ex post facto type of research, which is research on data collected after a fact or event occurs. The population in this study were students of class VIII of SMP Citra Bangsa Kupang. The data sources used in this study are pimer data and secondary data, with data collection techniques using learning motivation questionnaire sheets. After getting all the data, the next step is to draw conclusions from this study by analyzing the data. The technique used to analyze this research is descriptive quantitative. The results of the research obtained are that student learning motivation during online learning during the Covid-19 pandemic is in the moderate category with an average score of 64. Student learning motivation during offline learning after the COVID-19 pandemic is in the high category with an average score of 82.4. There are differences in student learning motivation in participating in the online and offline learning process where student learning motivation during offline learning is higher than student learning motivation during online learning.
Does Air Pollution Cause Obesity? New Evidence from China
Authors: Zhang Guanglai , Lin Bin , Ren Yayun 
Published: May 2023

The global obesity rate has risen at an alarming rate in recent decades, and “fatness” has become an increasingly serious public health problem. At the same time, the loss of working hours and increased medical costs caused by air pollution have a wide range of direct and indirect effects on the health of the population and the macroeconomy. Against this background, using data from the China Family Panel Survey (CFPS) and thermal inversion as instrumental variables, this study analyzes the effect of air pollution on the risk of obesity among residents. We employ a two-stage least squares method to identify the effects of air pollution on the risk of obesity. The findings indicate that for a 1 μg/m³ increase in the annual average PM2.5 concentration at the county level, the obesity level increases significantly by 0.0286. This result is credible after a series of robustness checks; male groups, less-educated groups, and rural residents are more sensitive to the negative effects of air pollution. Finally, policy suggestions are provided.

Authors: Nyabiba Jully Kemunto , Kimani E. Maina 
Published: May 2023

Purpose: The current study sought to establish the effect of portfolio diversification on financial performance of microfinance institutions in Kenya. The study focused on establishing the effects of asset class diversification, risk profiling diversification, income diversification and locational diversification on performance of microfinance institutions in Kenya. The study was supported by Shiftability Theory, Capital Market Theory, Resource Based Theory and Balanced Score Card Theory.
Methodology: A descriptive research design was used and targeted 57 micro finance institutions operating in Nairobi County and registered under Association of Micro Finance Institutions. The unit of observation comprised of employees in top level management including chief financial officer, operational manager, and chief manager making a total of 171 respondents. The study employed a census approach. Both primary and secondary data were utilized in the study. Primary data was gathered using a five point Likert scale questionnaire while a secondary data collection sheet was utilized to collect secondary data from financial reports of the respective institutions. Both descriptive and inferential statistics was used to analyze the collected data. The statistics were generated through Statistical Package for Social Scientists and MS Excel.
Findings: The results were displayed in form of tables. The study established that portfolio diversification comprising of asset class, risk profiling, and income diversification positively and significantly affect financial performance of the MFIs operating in Nairobi County as shown by respective beta values of 0.318, 0.288 and 0.498 and significant values of 0.000, 0.005 and 0.000. This bears the implications that enhancing aspects of each of the portfolio diversification contributes to improved financial performance of the institutions. Locational diversification on the other had had a positive but insignificant effect on financial performance of the MFIs (beta=0.103, sig=0.000>0.05) which implies that enhancing aspects of locational diversification contributes insignificantly to financial performance of the MFIs.
Unique contribution to theory, practice and policy: The study provided recommendations to the management of the MFIs to enhance the levels of asset class diversification, risk profiling diversification, and income diversification since the practices bears positive and significant effect on financial performances of the MFIs.

Published: May 2023

Purpose: This article provides a discussion on the Philosophy of Utuism and tries to relate the concepts with other philosophies. The main idea is to help in understanding in depth the interrelationships between the concepts which creates clear view and connections for better understanding of our theme of the study.
Methodology: The different philosophies discussed brings out the existing relationships and differences that outlays the actual meaning, existence and application of Utuism.
Findings: As has been demonstrated by the protagonists of the Bantu philosophy, every individual being as an important element in the web of “Beings”, should demonstrate an awareness of his connection to the other human beings and by natural fairness to other beings in the created order. The human person ought to do this in consciousness and express an active positive embracement with other humans, the human individual realizes his own reality as a force in the matrix of the entire reality that is active.
Unique contribution to theory, practice and policy: Whatever presented by the term Utuism first and foremost flows from the linguistic usage, relatedness to other closely ‘near-meaning’ is essential.
Effect of low-calorie diet on psoriasis severity index, triglycerides, liver enzymes, and quality of life in psoriatic patients with non-alcoholic fatty liver disease

Published: May 2023

IntroductionChronic-plaque psoriasis is a chronic inflammatory dermatological disease. Obesity comorbidities, including non-alcoholic fatty liver disease, are highly prevalent in patients with chronic-plaque psoriasis. Recently, weight loss has been a highly recommended intervention to improve the severity of psoriatic symptoms, psoriasis-induced chronic systemic inflammation, psoriasis-associated cardiovascular risk factors, quality of life, and the efficacy of anti-psoriatic drugs. This study was designed to assess the effect of a 12-week low-calorie-diet intervention on aspartate transaminase, psoriasis severity (assessed via Psoriasis Area and Severity Index – PASI), alanine transaminase, quality of life (assessed via Dermatology Life Quality Index – DLQI), triglycerides, waist circumference (WC), and body mass index (BMI) in class I obese men with chronic-plaque and non-alcoholic fatty liver disease.Material and methodsSixty men with age ≥ 18 years with class I obesity and with chronic plaque psoriasis and non-alcoholic fatty liver disease were included in the study. All participants were randomly assigned to one of two groups: the first group as the low-calorie-diet group (30 men received immunosuppressive drugs, followed a low-calorie diet, and increased their energy expenditure through a daily 15,000-step outdoor walking program for 12 weeks) and the second as the control group
(30 men received immunosuppressive drugs only). The primary outcome consisted of the results of the area and severity index. Weight, BMI, WC, laboratory results such as triglycerides, liver enzymes (alanine transaminase and aspartate transaminase) as well as DLQI were considered as secondary outcomes.ResultsWhile no significant improvements were achieved in the measured variables of the control group, the low-calorie-diet group demonstrated significant improvement in all the measured variables.ConclusionsThe results of the present study confirmed that 12-week low-calorie-diet intervention controls BMI, increases the response of psoriasis to pharmacological agents and improves the quality of life. Diet interventions significantly control the elevated hepatic enzymes (aspartate and alanine transaminases) and triglycerides in male patients with chronic-plaque psoriasis and non-alcoholic fatty liver dis-ease.

The Early Reception of Tash Aw’s Narrative in Malaysia: An Ecocritical Interpretation of Harmony within Dissonance in The Harmony Silk Factory
Authors: Kuan Lam Chook , Mohsen Hamoud Yahya Ahmed , Binti Othman Wan Mazlini 
Published: May 2023

This article is part of the current ecocritical research that is being conducted on Tash Aw’s works. It attempts to analyse Tash Aw’s first novel The Harmony Silk Factory and investigate how he customizes the concept of harmony and dissonance in relation to human beings from the perspective of the recent and growing theory of ecocriticism. Through examining Aw’s novel, the manipulation of nature in the hope of illustrating the plot of a novel is studied thoroughly. In this article, the ecocritical theory is used to approach the phenomenon of harmony and dissonance in nature in the context of human-nature relationship in the chosen novel. The ecocritical theory assists in revealing with what perspectives the nature is portrayed by Aw in his first novel. The analysis of the novel reveals that there is a coherent harmony in dissonance in the bridge between human beings and their natural setting with the idea that human beings and nature are constantly influencing each other and causing different outcomes from even the slightest change. The implication of the research reveals that the human-nature relationship is indeed something that carries much weight and needs to be given much consideration to. It gives rise to the issue that human beings and nature are inextricably interconnected. By incorporating the Malaysian viewpoint and voice of Tash Aw in the current article, we have exposed how ecocriticism is instrumental in meeting its targeted scope in Malaysian literary context as a multinational area of scholarship.
