Authors: Boonruang Chatdanai , Won-In Krit , Dararutana Pisutti
Published: August 2022

Bismuth glasses have been prepared from a commercial-grade chemical glass mixture doped with potassium chromate in different contents. They have been melted at 1250 °C for 4 h, quenched in a metal plate, and annealed at 500 °C for 20 min. The surface morphology of glass samples has been examined using scanning electron microscopy (SEM). The dielectric properties have been investigated. UV-Vis-NIR absorption has been analyzed. The results show the growth of microcrystal precipitated in the glass matrix, and colors of glass change from colorless to green and opaque with the increasing content of potassium chromate. The density of glass decreases with the increasing content of potassium chromate. The UV-Vis spectra show strong absorption of UV. The chromium-doped glasses not only absorb the UV but also the violet and/or blue lights which depend on the chromium contents.

Authors: Baroot Abbad Al
Published: August 2022

This work demonstrates an alternative organic semiconductor-based ion sensor design, and effortless that avoids the use of membranes with sensitizer and separate compartments, unlike previous architecture. Instead, we simply dope an organic semiconductor with a specific sensitizer ionophore called valinomycin into a polythiophene casting solution that is used to manufacture organic thin-film transistors. Resulting OTFTs display near-Nernstian ion sensitivity of their threshold voltage within different potassium ion concentrations. The Nernstian ion sensitivity is 52±2 mV/dec, and the limit of detection is 15±5 μM.

Authors: Santosa Sri Juari , Nuryono Nuryono , Aisyah Fina Nur , Hadi Muhammad
Published: August 2022

Removal of Au(III) on a purified bagasse ash (BA) has been examined. The purified BA adsorbent was prepared through purification of a crude BA obtained from Madukismo sugarcane industry, Yogyakarta, Indonesia, using a mixed solution of HCl 0.1 M and HF 0.3 M and followed by HNO3 3 M. The HCl-HF-HNO3 purified BA contained quartz with silanol (Si-OH) and siloxane (Si-O-Si) functional groups and aromatic component. Removal of Au(III) on the HCl-HF-HNO3 purified BA was maximum at pH 4.2 with siloxane and silanol functional groups, but not aromatic component, took important role on the removal. At this optimum pH, the removal of Au(III) on the HCl-HF-HNO3 purified BA fitter to the second order removal kinetics model than the pseudo-first and pseudo-second order kinetics models indicating that adsorption was not the only mechanism for the Au(III) removal. The second order removal rate constants (k2) of Au(III) by HCl-HF-HNO3 purified BA was 3.32 x 102 L/mol min. In fact, reduction of Au(III) to Au metal also occurred as an addition to adsorption for the removal of Au(III) from aqueous solution.

Corporate Governance Compliance among the Listed Firms in Colombo Stock Exchange: Does Size Matter?
Authors: De Silva Lankadeva Dinukee , Wanniarachchige Manjula Kumara
Published: August 2022

Literature is conflicting on the determinants of corporate governance, particularly relating to emerging financial markets. Therefore, this study examined whether firm size affects corporate governance compliance based on firm-level data from 2016 to 2020 for a sample of 100 firms listed on the Colombo Stock Exchange selected using the systematic random sampling technique. Firm size was measured using the natural logarithm of total assets. A corporate governance index was used to measure corporate governance compliance on 18 board related best practices. Results of three random-effects panel regression models indicated that firm size has a statistically significant positive effect on corporate governance compliance. This implies that larger firms are better motivated or capable of complying with corporate governance due to their more extensive resource. This way they can benefit from the reduced agency cost and increased attractiveness for investors. Smaller firms might have considered compliance with corporate governance as less beneficial given the higher cost of compliance. Therefore, it would be more appropriate to make policies flexible enough in the application based on the firm-specific characteristics, such as the firm size. Even though attempts have been made to assess the effect of firm size on corporate governance using firm size as a control variable, this is the first study dedicated to investigating the size effect on corporate governance compliance in the Sri Lankan context.

Inappropriate self-medication usage has become a significant public health problem in all countries. This study is aimed to determine the perceived self-medication practices (SMP), associated factors and awareness on contraindications related to self-medication among undergraduates in a non-state university using a random sample of 138 undergraduates of the Faculty of Humanities and Sciences (FOHS) of Sri Lanka Institute of Information Technology (SLIIT). The required data were acquired from a structured questionnaire consists of 31 questions in four parts. It was found that only 87% of the respondents had practiced self-medication in the past three months. Covid-19 restrictions (48.4%) and believing consultation for mild illnesses is unnecessary (44.0%) were the major reasons for SMP. The gender, age category, residing province, living with whom, study year, nationality, and household monthly income are not significantly associated with status of SMP, but the presence of chronic illnesses was significantly associated. The percentage of having SMP for those having chronic illness (87.9%) is significantly higher (p<0.05) than that for no chronic illness (78.5%). There was a significant association between the type of medicine use for SM and the levels of SM (high vs low). Also, the attitudes towards the statement “SM is effective similarly, to medicines prescribed by a doctor” is significantly associated (p=0.07) with the levels of SMP. Headache (80.7%) and common cold (43.0%) were the major health conditions for SMP, while painkillers (83.2%) and vitamins and minerals (47.8%) were the most used types of medicines. Conducting educational programs in pharmaceutical aspects is recommended to improve healthy medicinal compliance among the undergraduate population in Sri Lanka.

Authors: Perera L. I. S.
Published: August 2022

An increase in single-parent households is noticeable in modern society and the academic performance of the senior school students living in single-parent households is affected negatively at large. Therefore, this study aims to discover the issues and challenges that single-parented students face in their academic performance at the senior secondary level. This study involved a hundred senior secondary students (Grades 10 & 11) from single-parent households, fifty of their parents, and fifty class teachers from the Moratuwa Educational Division. The sampling method was stratified random sampling and the strata are three school types. Primary data was acquired through three structured questionnaires and the secondary data was collected through test scores and school-based assessments. Only descriptive statistics were used to derive the inferences. The analysis found that the students from single-parent households experience low parental involvement in their academic activities for many reasons, confirming that 24% of single parents rarely attended parent-teacher meetings, and 38% never attended. The three main causes are stressful responsibilities (92%), lack of finance (88%) and no external help at home (82%). About 70% of students have expressed their dislikein attending school as well as engaging in academic work. Furthermore, 88% of the students have claimed that they have lost confidence in their single parents as well as their class teachers. 76% and 68% of grades ten and eleven students have obtained the class positions between (31-50) while only 4% and 2% of grade ten and eleven respectively have acquired the class positions between (1-10). It was revealed that psychological, social and economic aspects contribute to the achievement levels of the students. This study recommends that ground-level stakeholders in school management pay more attention to and help single parents and their children cope with their situations and enhance their academic performance.

Purpose This study aimed to compare treatment outcomes and toxicity profile between imaged-guided brachytherapy (IGBT) versus conventional brachytherapy (CBT) performed by the same practitioner during the same time period.Materials and Methods Medical records of 104 eligible patients who underwent brachytherapy for locally advanced cervical cancer were retrospectively reviewed. Fifty patients (48.1%) underwent IGBT, and 54 (51.9%) patients underwent CBT. All patients underwent concurrent chemoradiation with cisplatin. High-dose-rate intracavitary brachytherapy with dose prescription of 25-30 Gy in 4-6 fractions was performed for all patients. Late lower gastrointestinal (GI) and urinary toxicities occurred more than 3 months after the end of brachytherapy were included for comparative and dosimetric analyses.Results The median follow-up period was 18.33 months (range, 3.25 to 38.43 months). There were no differences in oncologic outcomes between the two groups. The IGBT group had lower rate of actuarial grade ≥ 3 toxicity than the CBT group (2-year, 4.5% vs. 25.7%; p=0.030). Cumulative equieffective D2cc of sigmoid colon was significantly correlated with grade ≥ 2 lower GI toxicity (p=0.033), while equieffective D2cc of rectum (p=0.055) and bladder (p=0.069) showed marginal significance with corresponding grade ≥ 2 toxicities in the IGBT group. Half of grade ≥ 3 lower GI toxicities impacted GI tract above the rectum. Optimal thresholds of cumulative D2cc of sigmoid colon and rectum were 69.7 Gy and 70.8 Gy, respectively, for grade ≥ 2 lower GI toxicity.Conclusion IGBT showed superior toxicity profile to CBT. Evaluating the dose to the GI tract above rectum by IGBT might prevent some toxicities.

Published: August 2022

Access to clean water by all is one of the UN Sustainable Development Goals. To achieve this, there is need to prepare sustainable materials for efficient water purification. This research aims to immobilize the Polyoxomatelate-Ionic Liquid (POM-IL), {[CH3(CH2)6]4N}7[α-PW11O39] on nanoporous carbon (NC) prepared from coconut shell to form an advanced material (POM-IL@NC) for effective removal of multiple contaminants from polluted water. The POM-IL@NC material was characterized by Fourier Transform-Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD) Analysis and Brunauer-Emmett-Teller (BET) method. The material was then tested respectively for the removal of copper and lead using Atomic Absorption Spectroscopy (AAS) and methylene blue using Ultraviolet-Visible (UV-Vis) Spectroscopy from simulated polluted waters via adsorption. The material was further subjected to antimicrobial analysis. The results showed that the POM-IL@NC material performed better than the pristine NC in the removal of copper, lead and methylene blue from the contaminated water. The POM-IL@NC also exhibited significant improvement in antimicrobial activity than NC against Escherichia coli and Staphylococcus aureus. This shows that the new material could effectively be applied for multiple contaminants treatment of polluted water.

One of the primary goals of the World Health Organization (WHO) is for every society to have an adequate supply of safe drinking water. This work aimed to assess the radiological and toxicity impact of ground water of Wurno Local Government Area. Uranium activity concentration from 45 water samples collected from different locations in the study area were determined using HpGe   detector, the result from the analysis was used to evaluate the annual effective dose due to ingestion of groundwater from the study area by the inhabitants.  Radiological and chemical toxicity risks were also calculated. High level activity was reported in Diggim while low activity level was reported in Nassarawa-Daje. The annual effective doses for adult, children and infants were estimated to be from 0.008 mSvy-1 to 0.32 mSvy-1. The highest risk cancer mortality value was found at Diggim with a value of 4.34 × 10-4 while the lowest value was observed at Nassarawa Daje with a value of 1.17 × 10-5. Chemical toxicity value ranged from 0.59 – 21. 79 µg.kg-1.day-1 with an average dose value of 5.12 µg.kg-1.day-1. The lifetime average daily dose (LADD) values were reported to be higher at Diggim and lower at Nassarawa-Daje with the values 21.79 µg.kg-1.day-1 and 0.59 µg.kg-1.day-1 respectively compared with 0.6 µg.kg-1.day-1 WHO limit standard. Significantly, the high activity level, and chemical toxicity risk reported from this study is an indication that the area may have developed some fractures of granitic strata in the subsurface geology that contributed to the wide distribution of radiation dose.

Podcasts, webquests, wikis, webblogs und vor allem Lern- und Erklärvideos sind heute vielfach als digitale Lernhelfer verbreitet. In Folge der vorangegangenen Schulschließungen im Zuge der Covid-19-Pandemie werden sie nun auch verstärkt im formalen Bildungskontext eingesetzt. So gab in einer forsa-Umfrage unter rund 1000 Lehrer*innen im April 2020 nahezu jede zweite Lehrperson aus dem Sekundarstufenbereich an, Erklärvideos während der Schulschließungen genutzt zu haben (vgl. forsa, 2020). Vor dem Hintergrund der stark differenzierenden Qualität von Lernvideos widmet sich der vorliegende Beitrag der Vorstellung eines empirisch validierten mehrdimensionalen Kriterienrasters. Für die Qualitätsanalyse vereint das Raster fachwissenschaftliche sowie fachdidaktische Kriterien zur Vermittlung gattungstypologischen Wissens zur Kurzgeschichte und mediendidaktische Erkenntnisse zur Qualität von Erklärvideos. (Angehende) Lehrpersonen sollen durch die Arbeit mit dem Raster einerseits für unterschiedliche Qualitätsebenen von Erklärvideos sensibilisiert und dadurch andererseits in ihrer Rolle als Gatekeeper in einer zunehmend digitalisierten Lernwelt gestärkt werden. Bevor die zentralen Dimensionen des Qualitätsrasters und zwei damit verbundene exemplarische Analysen ausführlich vorgestellt werden, gibt der Beitrag einen Überblick zu Lernvideos als Lerngegenstand und problematisiert in einem nächsten Schritt die Notwendigkeit von Qualitätskriterien zu diesen.

Published: August 2022

This study focuses on the parasites in Dascyllus trimaculatus fish in Bidong Island. Though D. trimaculatus is a common reef fish, there is lack on parasites studies of this fish in Malaysia. The objectives of this study are to identify metazoan parasites and analyse the prevalence and mean intensity the parasites in D. trimaculatus. Sampling was randomly conducted on a coral colony of 100 meters within a 15m depth at Pantai Pasir Cina, Bidong Island. This research resulted in the identification of a copepod Lernaeocera branchialis and a nematode from the family Camallanidae. The copepods collected in this study infected 20 out of 42 D. trimaculatus specimens, whereas the nematode-like parasites collected infected 18 of out of 42 D. trimaculatus. All copepods found in the gills of D. trimaculatus had a prevalence of 4.95 and mean intensity of 47.62%, while the nematode-like parasite, which were found in the brain, had 2.72 prevalence and 42.86% mean intensity. This elucidates that both parasites are categorised as having light level but common frequency of infection, and the current IUCN status of D. trimaculatus has not been reported to be harmed by parasites. Though the mean intensity of both parasites is not harmful, the prevalence are concerning and might increase in the future, with further incorporation and monitoring of climate change factors that may affect the damselfish.

Authors: FADZIL DHIYA HILLMAN , YUSLIZA MOHD YUSOFF , NGAH ABDUL HAFAZ
Published: August 2022

This paper examines the determinants of pro-environmental behaviour among university students. It uses the theory of planned behaviour in determining the factors that lead to such behaviour. The determinants consist of environmental awareness, psychological factors (motivation, moral norms, perceived behavioural control and attitude), environmental knowledge and personality traits (agreeableness, extroversion, conscientiousness, neuroticism and openness to experience). Data was collected using convenience sampling through self-administered surveys and online forms distributed to 400 students in a public university in Malaysia. Data was subjected to construct validity and reliability analysis. The findings highlighted that motivation, agreeableness and perceived behavioural control were positively related to the practice of pro-environmental behaviour, whereas environmental awareness, moral norms, attitude and environmental knowledge were negatively related. Some personality traits, namely neuroticism, openness to experience, conscientiousness and extraversion, did not show any significant relationship with the practice of pro-environmental behaviour. This study provides a scope to improvise and incorporate environmental practices into the habits of students by aligning their goals with the universities’ dimensions, including curriculum, campus operation, research and outreach activities. The results could make an important contribution in establishing a sustained green culture through a new university paradigm.

Published: August 2022

The advancement of technology has allowed the application of Unmanned Aerial Vehicle (UAV) for beach surveying to be used instead of theodolite method. This is still a debatable issue whether UAV can completely replace the theodolite method for future research. The studied area at Seberang Takir, Kuala Nerus is recognized as a critical erosion site and beach nourishment activity has been undertaken here on an approximately five year cycle. This study aims to show the potential of UAV application for coastal research. The results show that the elevation data of drone extracted from Digital Elevation Model (DEM) are match equivalent to the total station elevation data within 0.03 m. The beach profile graph of the drone and total station show significant differences in the steeper area. This study shows that the UAV image technique using a drone holds the potential for monitoring and quantifying the beach changes to levels of accuracy and precision that can be compared to the theodolite method. UAV has a big potential for beach monitoring and it is encouraged to be applied for further understanding of how and when they can be most useful.

In this paper we present modification of coupled integral equations method (CIEM) for calculating the characteristics of the accelerating structures. In earlier developed CIEM schemes the coupled integral equations are derived for the unknown electrical fields at interfaces that divide the adjacent volumes. In addition to the standard division
of the structured waveguide by interfaces between the adjacent cells, we propose to introduce new interfaces in places where electric field has the simplest transverse structure. Moreover, the system of coupled integral equations is formulated for longitudinal electrical fields in contrast to the standard approach where the transverse electrical fields are unknowns. The final vector equations contain expansion coefficients of the longitudinal electric field at these additional interfaces. This modification makes it possible to deal with a physical quantity that plays an important role in the acceleration of particles (a longitudinal electric field), and to obtain approximate equations for the
case of a slow change in the waveguide parameters.

Introduction. From an epidemiological approach, obesity can be considered as a risk factor for the development of some diseases, or as a disease in itself. Basically, the risk factors for the development of obesity are genetic, physiological and environmental, including unhealthy lifestyles. Non–healthy lifestyles are those that have the most influence as risk factors for the development or not of obesity. Objective. Determine whether or not each of two anthropometric indices has sufficient prognostic efficiency by combining sensitivity and specificity in a single expression using positive and negative likelihood ratios. Material and methods. Three hundred adult patients who attended the "Jose Maria Morelos" Integral Hospital were studied. As a reference test, the Equation of the Metropolitan Life Insurance Company was used. Results. The results for the positive likelihood ratios corresponded to 13.4 and 1.7 for the anthropometric indices Waist/Height Index and Waist/Hip Index, respectively. The results for the negative likelihood ratios corresponded, respectively, to 0.07 and 0.5 for the anthropometric indices Waist/Height Index and Waist/Hip Index. Conclusions. The results of the positive and negative likelihood ratios report sufficient prognostic efficiencies for the Waist/Height Index. On the other hand, the results of the positive and negative likelihood ratios report, respectively, insignificant prognostic efficiency and poor prognostic efficiency for the Waist/Hip Index.

Objective. To determine if raw seafood, marinated without heat, partially cooked with heat, and completely cooked with heat that are sold for human consumption in establishments in the city of Telchac Puerto, Yucatan, Mexico, represent potential risk factors for the development of acute gastroenteritis, wound infection, primary septicemia and secondary septicemia by Vibrio vulnificus species. Material and methods. Study conducted on a representative sample (n= 132) selected from the total of 200 samples from 38 establishments. From July 1 to December 31, 2019, 132 samples of seafood were studied. Using the Cornfield method, the estimation interval was constructed at the 95% confidence level. Results. In 37 (28.03%) samples an equal number of strains were isolated whose biochemical characteristics corresponded to Vibrio vulnificus. The prevalences obtained in raw marine foods, marinated without heat, partially cooked with heat and completely cooked with heat were 35.59%, 45.45%, 22.45% and 0.00%. The Cornfield estimation interval at the 95% confidence level for Vibrio vulnificus was 13.56% ≤ P ≤ 42.50%. Conclusion. Raw seafood, marinated without heat, and partially cooked with heat represent potential risk factors for Vibrio vulnificus for the development of acute gastroenteritis, wound infection, primary septicemia, and secondary septicemia.

Published: August 2022

The current study examined the impact of governance on stock market performance in Pakistan. The study employed the ARDL model using Pakistani data with complete relevant data for the period spanning from 1996 to 2018. The study reveals that quality of governance as captured by voice and accountability, political stability and absence of violence, government effectiveness, regulatory quality, the rule of law, and control of corruption positively affect stock market performance. The findings suggest countries with better developed political systems would favor stock markets with higher market capitalization, better turnover ratios, higher value in shares traded, and a greater number of listed companies.

Published: August 2022

En Ecuador, el Bachillerato Técnico (BT) tiene como objetivo incorporar a las y los jóvenes al mundo laboral. La Ley Orgánica de Educación Intercultural (LOEI), configura al Bachillerato Técnico para este objetivo, por lo cual el diseño curricular está basado en competencias laborales; para facilitar la inserción de los graduados en escenarios reales de producción. El Colegio de Bachillerato Beatriz Cueva de Ayora de la ciudad de Loja, ha sido considerado como referente de estudio con el fin de conocer la incidencia que tiene el Bachillerato Técnico, y su estructura curricular, dentro campo laboral. La perspectiva de estudiantes y docentes permite realizar un acercamiento a la ejecución de las directrices estatales en el sector educativo y su aplicabilidad y pertinencia dentro de la localidad. Asimismo, se pueden encontrar puntos críticos dentro del proceso enseñanza aprendizaje, sobre todo en cuanto al equipamiento de plantas de producción y vinculación con la realidad local: prácticas estudiantiles. Como parte del desempeño institucional, se analizó uno de los elementos de eficiencia: la inserción laboral de los egresados, posterior a la culminación de sus estudios.

Information Asymmetry and Card Debt Crisis in Taiwan
Authors: Chang Chih-Hsiung
Published: August 2022

Abstract
Following the Asian Financial Crisis, South Korea, Hong Kong, and Taiwan experienced card debt crisis in 2001, 2002 and 2005, respectively. Various countries have studied and tried to find the factors that lead to the card debt crisis, hoping that the proposed countermeasures can effectively solve the problem. However, these are only practical operations and observations. Therefore, through information asymmetry, this article constructs a model of card debt crisis from adverse selection and moral hazard, and theoretically provides the government or competent authority with a policy basis. This article employs document analysis, combined with qualitative and quantitative data, to test the research hypotheses. The verification result is supported regardless of hypotheses tests for adverse selection, or moral hazard and confirms that information asymmetry and market failure do exist in the Taiwan credit card market. The policy implication of the article is that the government or competent authority should stop the illusion of free market mechanism and have to be responsible for employing countermeasures to face the crisis.
