Obstructive Jaundice
Authors: Kim Sung Deuk
Published: January 2023

Jaundice is a medical condition in which the skin or sclera of the eyes becomes yellow, and elevation of bilirubin production or obstruction of bile excretion can cause jaundice while disrupting the balance between bilirubin production and bile excretion. Jaundice is a very visual clinical sign that both patients and physicians can easily recognize. It warrants further investigation regarding the cause of jaundice because jaundice is always a pathological sign regardless of its seriousness. Clinical manifestations of obstructive jaundice can be understood in terms of bile formation and secretion, and the anatomy of the biliary tree. Obstruction of a critical part of the biliary tree such as the common bile duct can cause jaundice, and investigating the etiology of jaundice is the first step of managing this condition. Choledocholithiasis, pancreatic ductal adenocarcinoma, cholangiocarcinoma, and biliary atresia are some of the common medical conditions that cause obstructive jaundice. Whenever jaundice is observed by a physician, early diagnosis and prompt treatment should be performed as early as possible for better outcomes.
A Case of Hyperinsulinemic Hypoglycemia in Premature Infant Treated with Oral Diazoxide
Authors: Pyeon Jeong Eun , Jeong Hwal Rim , Koh Ji Won
Published: January 2023

Neonatal hyperinsulinism, whether permanent or transient, results in prolonged hypoglycemia, which increases the risk of hypoglycemic brain injury. Therefore, prompt diagnosis and management of hyperinsulinemic hypoglycemia is important. Drawing a “critical sample” at the time of hypoglycemia is useful for diagnosis. Genetic testing for defective insulin-regulating genes in pancreatic beta-cells might also be helpful in cases of prolonged hypoglycemia. High-calorie feeding or glucose infusion is necessary to maintain normoglycemia. Diazoxide is the treatment of choice for hyperinsulinism and should be continued until the hypoglycemia resolves. We describe a case of transient neonatal hyperinsulinemia hypoglycemia in a small-for-gestational-age preterm infant who underwent diazoxide treatment and achieved a favorable outcome.
North Atlantic Right Whale Consortium 2006 Annual Report Card
Authors: Pettis Heather M. , Hamilton Philip K.
Published: January 2023

The North Atlantic right whale (Eubalaena glacialis) remains one of the most endangered large whales in the world. Over the past two decades, there has been increasing interest in addressing the problems hampering the recovery of North Atlantic right whales by using innovative research techniques, new technologies, analyses of existing databases, and enhanced conservation and education strategies. This increased interest demanded better coordination and collaboration among all stakeholders to ensure that there was improved access to data, research efforts were not duplicative, and that findings were shared with all interested parties. The North Atlantic Right Whale Consortium, initially formed in 1986 by five research institutions to share data among themselves, was expanded in 1997 to address these greater needs. Currently, the Consortium membership is comprised of representatives from more than 100 entities including: research, academic, and conservation organizations; shipping and fishing industries; whale watching companies; technical experts; United States (U.S.) and Canadian Government agencies; and state authorities. North Atlantic Right Whale Consortium members agreed in 2004 that an annual “report card” on the status of right whales would be useful. This report card includes updates on the status of the cataloged population, mortalities and injury events, and a summary of management and research efforts that have occurred over the previous 12 months. The Board’s goal is to make public a summary of current research and management activities, as well as provide detailed recommendations for future activities. The Board views this report as a valuable asset in assessing the effects of research and management over time.

Twenty-year changes in the clinical and echocardiographic characteristics of patients with early postinfarction remodeling after primary ST-segment elevation myocardial infarction
Authors: Nikolaeva A. M. , Ryabova T. R. , Sokolov A. A. , Ryabov V. V.
Published: January 2023

Aim. To compare structural and functional left ventricular (LV) changes in the early period of myocardial infarction (MI) within 20 years on the basis of the Emergency Cardiology Department of the Cardiology Research Institute (Tomsk).

Material and methods. The study included two groups of patients who were treated at different periods of time with an interval of 20 years. Group 1 included 83 patients who had ST-segment elevation MI (STEMI) in 1997-1999, while group 2 — 83 patients with STEMI from 2019-2020. Echocardiography was performed during the first 72 hours from hospitalization and on the 7-10th day. Depending on the increase in LV end-diastolic volume (EDV) by >15% by the 7-10th day, the patients were divided into 2 subgroups: with remodeling (LVR+) and without remodeling (LVR-).

Results. Patients of the 2nd group were older, with a larger proportion of females and with a high incidence of risk factors for coronary artery disease compared with patients of the 1st group. In the early postinfarction period among patients of the 2nd group, acute LV aneurysm, early postinfarction angina and Dressler syndrome developed less frequently. The proportion of adverse LV remodeling in patients of the 1st group was higher (32,8% vs 17%), and while the percentage of reverse remodeling was lower (10% vs 24%), p<0,05. Comparison of the absolute values of LV EDV, end-systolic volume (ESV) and ejection fraction (EF) at baseline and after 7 days, as well as their increase showed higher intensity of post-infarction remodeling in group 1 patients. In patients of the 1st group, there was a progression of LV remodeling (Me ΔEDV — 12,2%) with a deterioration in LV contractility by the 7th day (Me ΔESV — 14%), while in patients of the 2nd group during the first 7 days of MI, there were more stable LV EDV and ESV (p>0,05) and an increase in LVEF (p=0,03) before discharge.

Conclusion. In the present era of primary percutaneous coronary intervention and pharmacological treatment of MI, early adverse LV remodeling develops less frequently and is characterized by less pronounced left heart dilatation.

Authors: Ilov N. N. , Stompel D. R. , Boytsov S. A. , Palnikova O. V. , Nechepurenko A. A.
Published: January 2023

Aim. To carry out a comparative analysis of left ventricular (LV) strain parameters, determined by the two-dimensional strain imaging in patients with heart failure (HF) with LV ejection fraction (EF) ≤35%, depending on the origin of HF.

Material and methods. The study included 133 patients with NYHA class 3-4 HF with LVEF ≤35%, taking optimal therapy. Based on the HF origin, 2 following groups of patients were formed: ischemic cardiomyopathy (ICM) (n=70), nonischemic cardiomyopathy (NICM) (n=63). All patients underwent speckle-tracking echocardiography.

Results. All patients included in the study showed significant alterations in longitudinal strain parameters in most myocardial segments, most pronounced in the basal and middle parts of the LV. Comparative analysis of the peak systolic longitudinal strain showed the worst characteristics in patients with ICM were found in the apical segments (p=0,008), and in patients with NICM, in the basal segments of the LV (p=0,046). The studied groups had comparable LV global longitudinal and circumferential strain (p=0,26; p=0,67; respectively).

Conclusion. Groups of patients with HF of ischemic and non-ischemic origin, despite comparable LVEF values, differ in the distribution of the decrease in local longitudinal strain of LV segments. The worst strain characteristics in patients with ICM and NICM are detected in LV apical and basal segments, respectively.
Aspects of transthoracic echocardiography protocol in obese patients

Published: January 2023

Often, transthoracic echocardiography in obese patients reveals normal indicators of intracardiac hemodynamics and heart geometry. Can the clinician determine the risk of cardiovascular events and proper management in such patients based on the data obtained? Do many overweight patients really have no cardiac abnormalities, or they simply could not be detected? New capabilities of transthoracic echocardiography make it possible to detect abnormalities in the early stages of the disease, even in the absence of clinical manifestations. Thus, the inclusion of additional parameters in the standard protocol of echocardiography in obese patients will most accurately determine the management tactics and prognosis, thereby reducing the risk of unfavorable outcomes.
HEAT-TRANSFER ENHANCEMENT OF MONO ETHYLENE GLYCOL-WATER-BASED SOLAR THERMIC FLUIDS DISPERSED WITH MULTIWALLED CARBON NANOTUBES IN A COILED TUBE HEAT EXCHANGER

Published: January 2023

The current research focuses on how the inclusion of multiwalled carbon nanotubes (MWCNTs) in mono ethylene glycol-water mixtures affects thermal conductivity, heat transfer, and dynamic viscosity for solar thermal applications. To achieve high stability in mono ethylene glycol-water mixtures, MWCNTs were oxidized and then dispersed at concentrations of 0.5, 0.25, and 0.125 wt.%. Zeta potential analysis was used to track the stability of the nanofluids over a two-month period. With the dispersion of MWCNTs in the base fluids, there is a remarkable increase in thermal conductivity from 15 to 24%. The dynamic viscosity variation is found to be minimal at high temperatures. Heat-transfer studies conducted on a specially designed test rig consisting of a coiled heat exchanger show that ethylene glycol-water mixtures dispersed with MWCNTs exhibit excellent performance under laminar conditions. Correlations for thermal conductivity, dynamic viscosity, and Nusselt number were obtained for all temperature conditions, mass fractions, and percentages of ethylene glycol. In the case of 100% mono ethylene glycol and mono ethylene glycol-water mixtures (90:10 and 80:20) as base fluids, the increase in heat-transfer coefficients of the corresponding nanofluids is up to 30, 26, and 25%, respectively.

Published: January 2023

Male menopause, also referred to as late-onset hypogonadism or andropause, is a clinical syndrome characterized by sexual dysfunction, depressive disorder, and insomnia secondary to a testosterone deficiency in older men. Lespedeza cuneata, which belongs to the Fabaceae family, possesses several biological properties, including antiinflammatory, anti-oxidant, and antidiabetic effects. We investigated the inhibitory effect of standardized L. cuneata extract (LCE) on andropause symptoms in vivo. LCE administration significantly increased serum levels of total testosterone without any effects on serum estrogen levels. Additionally, LCE significantly increased serum 17-beta hydroxysteroid dehydrogenase 13 protein levels and reduced levels of sex hormone-binding globulin (SHBG), a protein that blocks free testosterone movement into the cytosol. LCE significantly upregulated the expression of cAMP response element binding protein and androgen receptor (AR), which functions as a transcription factor to stimulate spermatogenesis-associated genes and results in increased numbers of AR-positive cells, such as Leydig and Sertoli cells in the testis. To summarize, LCE administration increases serum testosterone, reduces SHBG levels and upregulates AR expression. Therefore, LCE may be useful as alternative therapy for andropause in older men.

THE EFFECTIVENESS OF URL FEATURES ON PHISHING EMAILS CLASSIFICATION USING MACHINE LEARNING APPROACH
Authors: Naswir Ahmad Fadhil , Zakaria Lailatul Qadri
Published: January 2023

Phishing email classification requires features so that the performance obtained produces good accuracy. One of the reasons for the lack of development of models for detecting phishing emails is the complexity of the feature selection. Feature selection is one of the essential parts of getting a good classification result, commonly used features are header, body, and Uniform Resource Locator (URL). Besides the email body text content, the URL is one of the leading indicators that the phishing attack successfully happened. The URL is commonly located on the body of the phishing email to get the victim's attention. It will redirect the victim to a fake website to obtain personal information from the victim. There is a lack of information about how the URL features affect the phishing email classification results. Therefore, this work focuses on using URL features to determine whether an email is phishing or legitimate using machine learning approaches. Two public datasets used in this work are the Online Phishing Corpus and Enron Corpus. The URL features are extracted using the Beautiful Soup library. Two machine learning classifiers used in this work are Support Vector Machine (SVM) and Artificial Neural Network (ANN). The experiments were divided into two based on features used in the classifiers. The first experiment used raw email data with URL features, while the second only used raw email data. The first experiment shows higher accuracy in both classifiers, SVM and ANN. Hence, this research proves that the impact of selecting URL features will increase the performance of the classification.

Published: January 2023

Early Mathematics is one of the critical subjects where the concept of learning needs to be introduced to early-stage students so that there is no perception of this subject. In the 1970s, teaching methods for Mathematical concepts have traditionally been more on memorization. The purpose of this research was to increase students ?understanding of the topic of patterns in Early Mathematics by integrating Augmented Reality applications. The study of the development of this module was conducted using the TUP model (Technology, Usability, Pedagogy) from the Bednarik TUP Model was implemented to evaluate the technology, usability, and pedagogy to evaluate the effectiveness of the modules produced. The study found that students are more interested and show their interest in the class, parents are also involved in student learning, and teachers are able to implement teaching sessions based on discussion better when they are given more opportunities to be actively involved in the classroom. In addition to active learning in the classroom, the combination of technology also plays an important role in the flow of current learning methods.

Medical and health professionals who actively share and discuss health information through social media to influence their followers are known as social media health opinion leaders. However, the parasocial relationships between social media health opinion leaders and their followers can influence the opinions, emotions, attitudes, and effective actions of the followers towards leading a healthy lifestyle. Therefore, this study was conducted to identify the strategies employed by social media health opinion leaders when using social media to communicate health issues. This study integrated the process model of health parasocial opinion leadership on social media by Saw et al. as the study guide. An in-depth interview was conducted with five (5) social media health opinion leaders on Twitter. The results of the study show that social media health opinion leaders use a variety of strategies depending on the topic of discussion to effectively convey information to their followers. The strategies revealed in the study show that the delivery and sharing of information by social media health opinion leaders play an important role, namely in reducing information complexity, health orientation, stimulating interest, correcting information and mythic perceptions, and strengthening the image and ethics of medical professionalism. However, there is no emotional stimulation for those who follow their favourite social media health opinion leaders. As a result, the study suggests that social media health opinion leaders improve their emotional stimulation strategies to add value to the quality of parasocial relationships with their followers, thereby strengthening their relationship with their followers. Keywords: Opinion Leadership, parasocial relationship, parasocial opinion leadership, health communication, social media.

Along with the consistent increase in the COVID-19 vaccination rate, the Indonesian government continues to strive to control the pandemic with various policy programmes. On the other hand, the vaccination programme has also been expanded to 6-11 years school children to foster the implementation of school reopening despite many debates and controversies circulated in the country. Identifying parental health beliefs toward vaccination, this study aims to examine factors influencing parental intention to vaccinate their children. An online survey was conducted to attain responses from 400 study participants from 9 selected provinces. The data were analysed using descriptive and inferential statistical techniques on the SPSS version 26. This study revealed that vaccination acceptance is high among parents in Indonesia. Parents’ intention to vaccinate their children was significantly influenced by health beliefs. The multiple regression analysis suggested perceived susceptibility (β = .146, p = .012), perceived benefits (β = .249, p = .000) and cues to action (β = .220, p = .000) as significant predictors which positively influenced the vaccination intention, while the perceived barrier (β = -.316, p = .000) was identified as a negative predictor of the dependent variable in the model. There was a significant mean difference in parental intention within gender, age group, and household income. The findings of this study emphasised the need to provide a more strategic health messaging and health education programme to address the issues surrounding the barriers to implementing vaccination for children in Indonesia. Keywords: COVID-19, vaccine acceptance, health belief model, school children, Indonesia.

Published: January 2023

Social media communication has its own language features and one aspect is modified spelling of standard words. Social media users use shortened words with full awareness of the meanings, and new non-standard words are constantly added to the repertoire of social media language. A pertinent question is whether social media users learn these non-standard words to use or whether they also contribute to the vocabulary used in social media communication. The study examined Malaysian millennials’ use of non-standard words in Twitter and their reasons for shortening words. For the non-standard words, data were collected from 200 active Twitter users whereas data on reasons for shortening words were collected from 30 users. The results showed that the Malaysian millennials frequently used non-standard spelling of words. The three top words were “ni” (this), “nak” (want), and X (negation). The main reasons for the Twitter users to shorten words were the 280-character limit per tweet, user convenience, and characteristics of words. The Twitter users felt free to create new spellings of standard words at times for fun, but most of the time, they use the common non-standard words. The Malaysian millennials reported that they were inclined to shorten long and complex words, and words with many vowels. The study suggests that Twitter users balance between speed in communication and preservation of meaning when using non-standard words. Keywords: Social media, Twitter, non-standard words, word formation processes, shortening of words.

Supply chain management (SCM) involves an interconnected structure of facilities that produces elements or compounds for transforming into a semifinished compound. After completion, the final compound is delivered to customers via a distribution system. Owing to ever-changing customer demands, increasingly efficient and resilient SCM is necessary, which requires support from the latest technologies. Therefore, this paper presents an overview of the latest technologies in SCM and logistics. The management of a supply chain and role of the different actors involved differ from industry to industry and company to company. Consequently, SCM has become a crucial issue to manufacturers, professionals and researchers. The latest technologies identified in this paper include radio frequency identification, vehicular ad hoc networks, the Internet of things, robotics and artificial intelligence and blockchain. Moreover, the application of the aforementioned technologies in different industries and systems is discussed to understand how the technologies impact practitioners. Although not discussed thoroughly, other recent technology trends in SCM and logistics, such as machine learning, autonomous vehicles/drones, advanced analytics, cloud logistics, supergrid logistics, anticipatory logistics, omnichannel logistics and additive manufacturing (3D printing), are also highlighted in this paper. By understanding the advancements in SCM technology, the possible direction of future innovations can be effectively planned and articulated.

Artificial intelligence (AI) algorithms of adaptive neuro-fuzzy inference system or the adaptive network-based fuzzy inference system (ANFIS) has been deployed to predict the swelling potential (SP) of treated weak soil. The soil was treated with quicklime activated rice husk ash (QARHA) and the prediction efficiency was compared with the previous outcomes of this operation from literature. The need for effective utilization of construction materials to achieve sustainable designs and monitoring of the behavior of built environment is the motivation behind the deployment of artificial intelligence in geo-environmental research and field operations. The use of ANFIS is common in different fields of science and business to predict the best fits from several data points. The results of this modeling exercise conducted with 25 datasets from mixture experimental treatment of soft soil with QARHA has shown that ANFIS is a better tool compared to the individual algorithms of ANN and FL and even the other artificial intelligence tools like scheffe, ANOVA, regression and extreme vertices methods. With performance index of 88% and correlation of about 71% in the ANFIS testing and 17% and 99% respectively in the ANFIS training, ANFIS proved to be a more powerful tool in achieving a more sustainable material utilization in earthwork constructions, design and monitoring of geotechnical systems performance.

Most village houses in Malaysia discharged lots of significant portion of greywater into stream or drains without any treatment. This phenomenon of direct disposal of greywater into the environment caused environmental risk, especially to water body. This study aimed to assess the quality and treatment of greywater discharge using pottery waste ceramic filter (PWCF) for safe disposal. Greywater samples were collected from 27 village households located at Kampung Parit Sempadan, Parit Raja using grab sampling method. Greywater was treated by using PWCF. The effectiveness of the PWCF was optimized using different sizes (0.25, 0.60, and 1.18 mm) of ceramic filter media at different hydraulic retention times (HRT: 1, 2, and 3 h). The t-test analysis showed significant differences between greywater from the two drainage distances. The results revealed that a distance within 81–100 m was significant to the influence of gender and the number of household occupants of the greywater discharged. The results of this study highlight that PWCF reduced the concentration of COD, BOD and TSS in greywater by 99.4%, 74.3 and 100% respectively using particle size of 0.25 mm and HRT of 3 hours. Finally, it deduced that the use of PWCF was effective and can enhance the quality of greywater for safe disposal.
