Authors: Mohd Nasir Noormahayu Binti , Nasir Zarul Azhar , Abdullah Fahami Norasyikin , Ahmad Kusairee Muhammad Adidinizar Zia , Ramli Khalijah
Published: December 2021

This study aims to analyse the relationships between income level, education expenditure, inflation, and ageing population towards health expenditure in Malaysia over the period of 1997 until 2017.  This study employs Autoregressive Distributed-Lag (ARDL) Bound test in determining the long-run empirical relationships between all independent variables and healthcare expenditures in Malaysia.  The findings show the existence of long run cointegration between healthcare expenditure inflation, income level, and the government’s education expenditure.  The results confirmed that all independent variables have positive long run relationships, except the ageing population that displays a negative relationship in influencing healthcare expenditure in Malaysia. The regression result of GDPP shows income elasticity value of 0.690, reflecting the necessity of healthcare expenditure. The outcome of the paper hopes to provide insights on the importance of healthcare expenditure for the development of this country, especially on its economic fronts.

Authors: Pu Song , Ahmad Nor Aniza , Md. Khambari Mas Nida , Keng Yap Ng , Ahrari Seyedali
Published: December 2021

Abstract. The purpose of this study is twofold: 1) to develop a service-learning-based module training artificial intelligence (AI) subject (SLBM-TAIS), and 2) to evaluate the effect of SLBM-TAIS on pre-service teachers’ (PSTs’) practical knowledge and motivation, as well as primary school students' attitude towards AI in China. Participants of this study comprised 60 PSTs and 107 primary school students. The experimental research in this study followed the quasi-experimental non-randomized pre-test and post-test control group design. The PSTs were divided into experimental and control groups, and the primary school students followed the same grouping. The PSTs in the experimental group taught AI subjects to the primary school students in the experimental group, while the PSTs in the control group taught AI subjects to the primary school students in the control group. The results of the study showed that SLBM-TAIS was effective in training PSTs to teach AI subjects to primary school students. Furthermore, the SLBM-TAIS developed in this study offered a unique technique for training PSTs and primary school students that could increase PSTs' practical knowledge and motivation, as well as primary school students' attitudes toward AI. The findings from this study are important in the field of educational psychology, and its contribution has several theoretical and practical implications.

Authors: Amran Muhammad Syawal , Abu Bakar Kamariah , Surat Shahlan , Mahmud Siti Nur Diyana , Mohd Shafie Amirul Anwar Bin
Published: December 2021

Abstract: Creativity in teaching is important in order to ensure children are engaged in learning Science, Technology, Engineering and Mathematics (STEM). However, previous research has claimed creativity in learning STEM for children is not adequately supported by teacher in classroom due to the lack of preparation, content knowledge and skills. This study aims to assess the needs and challenges of promoting creativity in STEM education. In this study, preschool teachers (n= 22) were interviewed as they are the key informants who are involved in STEM education. The semi-structured interviews were analysed using qualitative content analysis and were qualitatively coded. Results illustrate that there are several distinctive themes identified as described by the participants when discussing the needs and challenges of implementing integrated creativity skill in STEM education as well as the support that would be most helpful in overcoming them. The results highlighted a huge gap between creativity knowledge and the implementation of creativity in STEM education. Participants also provided specific support needed to integrate creativity in STEM education. Preliminary findings suggest that many teachers are interested in integrating creativity skills in STEM education. This research sheds light on the needs and challenges for professional pre-school teachers by providing them pedagogical module as well as professional training to promote creativity in teaching STEM

Authors: Mancini Clara Elisa , Cayo Gisela Paola
Published: December 2021

El presente trabajo analiza el caso de la aplicación del proyecto de Corporación Andina de Fomento (CAF)– Banco de Desarrollo de América Latina: “Empoderamiento socioproductivo de comunidades vulnerablesen Jujuy (2018-2020)”. La finalidad de dicho proyecto radica en el desarrollo de emprendimientos de Turismo Rural Comunitario (TRC) entre comunidades originarias del Zenta, en los Departamentos de Humahuaca y de Valle Grande (Jujuy, Argentina). En muchos casos se han cuestionado los impactos del auge del turismo y la patrimonialización por ser los desencadenantes de la expansión urbana, la periferización de las principales ciudades quebradeñas y la ocupación de áreas de riesgo hídrico. El TRC intenta ubicarse como la contracara de ese turismo, y promueve el desarrollo rural y apoya las comunidades para que no tengan que trasladarse desde sus regiones hacia las áreas centrales en busca de empleo o para mejorar la calidad de vida. Con este fin, se analizarán los elementos constitutivos de la política pública. Luego, se discutirán las características del territorio de la Quebrada de Humahuaca, y de la región del Zenta en particular, los procesos de transformación recientes. Finalmente, se evaluará la política en relación con las implicancias en el territorio.
Keratometry, biometry, and prediction of intraocular lens power in adult tigers (Panthera tigris)
Authors: Owens Cameron D. , Michau Tammy M. , Boorstein Justin , Wynn Elizabeth R. , McMullen Richard J.
Published: December 2021

OBJECTIVE

To calculate the necessary pseudophakic intraocular lens (IOL) power to approximate emmetropia in adult tigers.

ANIMALS

17 clinically normal adult tigers.

PROCEDURES

33 eyes of 17 clinically normal adult tigers underwent routine ophthalmic examination and B-scan ultrasonography while anesthetized for unrelated procedures. Specific ultrasound data (globe measurements and corneal curvature) and estimated postoperative IOL positions were utilized to calculate predicted IOL power by use of Retzlaff and Binkhorst theoretical formulas. Applanation tonometry and refraction were also performed.

RESULTS

Mean ± SD axial globe length was 29.36 ± 0.82 mm, preoperative anterior chamber depth was 7.00 ± 0.74 mm, and crystalline lens thickness was 8.72 ± 0.56 mm. Mean net refractive error (n = 33 eyes) was +0.27 ± 0.30 diopters (D). By use of the Retzlaff formula, mean predicted IOL power for the postoperative anterior chamber depth (PACD), PACD – 2 mm, and PACD + 2 mm was 43.72 ± 4.84 D, 37.62 ± 4.19 D, and 51.57 ± 5.72 D, respectively. By use of the Binkhorst equation, these values were 45.11 ± 4.91 D, 38.84 ± 4.25 D, and 53.18 ± 5.81 D, respectively. Mean intraocular pressure for all eyes was 14.7 ± 2.69 mm Hg.

CLINICAL RELEVANCE

The calculated tiger IOL was lower than reported values for adult domestic felids. Further studies evaluating actual PACD and pseudophakic refraction would help determine the appropriate IOL power to achieve emmetropia in this species.

Authors: Domenegato Briana M. , Côté Etienne , Agarwal Deepmala , O’Sullivan M. Lynne , Reveler Elaine D. , Dobbin Elizabeth , McMahon Ellen
Published: December 2021

OBJECTIVE

To compare potassium concentrations in feline plasma and serum samples analyzed promptly after collection or after 20 to 28 hours of refrigerated storage.

ANIMALS

41 cats.

PROCEDURES

A venous blood sample was obtained from each cat. Aliquots were placed in 2 tubes without anticoagulant (blood was allowed to clot to derive serum) and 2 tubes with heparin (to derive plasma). One serum and 1 plasma sample were kept at room temperature and analyzed within 60 minutes after collection (baseline); the other serum and plasma samples were analyzed after 20 to 28 hours of refrigerated storage. At both time points, serum and plasma potassium concentrations were measured.

RESULTS

Median baseline serum potassium concentration (4.3 mmol/L) was significantly higher than median baseline plasma potassium concentration (4.1 mmol/L). The median difference between those values was 0.4 mmol/L (95% CI, 0.2 to 0.5 mmol/L). Compared with their respective baseline measurements, the median serum plasma concentration (4.8 mmol/L) and median plasma potassium concentration (4.6 mmol/L) were higher after 20 to 28 hours of refrigeration.

CLINICAL RELEVANCE

Results indicated that with regard to potassium concentration in feline blood samples, clotting or refrigerated storage for 20 to 28 hours results in a significant artifactual increase. Detection of an unexpectedly high potassium concentration in a cat may represent pseudohyperkalemia, especially if the blood sample was placed in a no-additive tube, was stored for 20 to 28 hours prior to analysis, or both.

Authors: Ropciuc Sorina , Oroian Mircea , Leahu Ana , Damian Cristina
Published: December 2021

The aim of this study was to determine the rheological characteristics of the dough at the addition of purple potato powder in different quantities (0-100 g). The wheat flour types 480 and 1250 were used. The rheological characteristics of the dough were determined with the help of Chopin Alveograph analyzing the tensile strength. The rheological measurements were made with the HAAKE RheoWin Mars 40 rheometer and the dough’s viscoelastic modulus was analyzed at the frequency of 1-20 Hz. The bread samples were analyzed in terms of volume, porosity, color and texture. The textural parameters determined with the help of the texturometer were the elasticity, adhesiveness and stickiness of the bread crumb. It has been found that the addition of purple potato dough does not adversely alter the rheological properties of the dough. The elasticity and stickiness of the bread core increases with the increase of potato addition in the case of whole-grain flour. The color of the bread intensifies as the dose of purple potato powder increases.
Access Control Models
Authors: Penelova Maria
Published: December 2021

Access control is a part of the security of information technologies. Access control regulates the access requests to system resources. The access control logic is formalized in models. Many access control models exist. They vary in their design, components, policies and areas of application. With the developing of information technologies, more complex access control models have been created. This paper is concerned with overview and analysis for a number of access control models. First, an overview of access control models is presented. Second, they are analyzed and compared by a number of parameters: storing the identity of the user, delegation of trust, fine-grained policies, flexibility, object-versioning, scalability, using time in policies, structure, trustworthiness, workflow control, areas of application etc. Some of these parameters describe the access control models, while other parameters are important characteristics and components of these models. The results of the comparative analysis are presented in tables. Prospects of development of new models are specified.
A Fuzzy Approach to Multi-Objective Solid Transportation Problem with Mixed Constraints Using Hyperbolic Membership Function
Authors: Kara Nurdan , Kocken Hale Gonce
Published: December 2021

Multi-objective Solid Transportation Problem (MSTP) is known as a special class of vector-minimization (or maximization) problems and has three parameters: source, destination, and conveyance. The objectives such as transportation cost, transportation time, transportation safety level, and objectives in terms of environmental and social issues are generally in conflict with each other. In this paper, we present a fuzzy approach to bring these conflicting objectives together as high as possible. Instead of using the linear membership function, which is frequently used in the literature for ease of use, we use the hyperbolic membership function in our approach. Also, while most of the papers in the literature deal with the standard equality constrained form of MSTP, the mixed constrained form is addressed in this paper. Finally, a numerical example from the literature is used to illustrate the construction of the hyperbolic membership function and how well it represents the objective functions’ degree of satisfaction.
Ta’ awun behavior, work stress, worklife balance in Islamic perspective and employee performance : investigation in Indonesia
Authors: Muafi Muafi
Published: December 2021

Ta’ awun behavior is very rarely being studied in business research especially when associated with employee performance. This study examines and analyzes the partial effect of: (1) ta’ awun behavior on employee performance, work stress, and work-life balance in Islamic perspective (WLBIP), (2) work stress and WLBIP on employee performance and (3) the mediating role of work stress and WLBIP in the relationship between ta’ awun behavior on employee performance. Data is collected through distributing questionnaires to employees of financial services companies in the Special Region of Yogyakarta with purposive manner. The statistical technique uses Partial Least Square. The results prove that ta’ awun behavior is partially able to make a positive contribution to the employees performance and WLBIP. Ta’ awun behavior also reduces work stress. Employee work stress reduces employee performance and WLBIP improves employee performance. Work stress is able to mediate ta’ awun behavior on employee performance, but WLBIP is not able to mediate it. This study implies that the research model can be applied to employees of business companies, which so far have focused on social and community institutions.

PREDIKCIJA RIZIKA I KLASIFIKACIJA OZBILJNOSTI SUDARA MOTORNIH VOZILA U NJUJORKU
Authors: Škipina Milica
Published: December 2021

Svake godine u saobraćajnim nesrećama na putevima širom svijeta pogine 1,35 i bude povrijeđeno 20-50 miliona ljudi, što znači da svakog dana u prosjeku skoro 3.700 ljudi izgubi život u saobraćaju. Više od polovine poginulih su pješaci, motoristi ili biciklisti. U ovom radu će biti analizirani faktori koji direktno utiču na povećanje vjerovatnoće pojave sudara motornih vozila, a zatim predstavljena metodologija za predviđanje rizika kao i klasifikaciju nivoa ozbiljnosti sudara korištenjem klasifikacionih modela mašinskog učenja. Predloženi model objedinjuje podatke o sudarima, ulicama Njujorka, protoku saobraćaja na pojedinim dionicama i podatke o vremenu i može se koristiti za identifikaciju gdje i kada je rizik od nesreće značajno veći od prosjeka kako bi se preduzele radnje za smanjenje tog rizika. Rezultati modela za predikciju sudara dostižu tačnost od 70%, dok model za klasifikaciju ozbiljnosti sudara postiže makro-prosječni F1-skor od 0,56.

A Student-Directed Community Cardiovascular Screening Project at a Regional Campus
Authors: Crump William J. , Doyle Emma C. , Southall William R. , Edmonson Blake S.
Published: December 2021

Introduction
Cardiovascular disease (CVD) is an important threat to public health, especially in rural communities. Clinical medical students at a rural regional campus can be a valuable resource to plan and implement CVD risk factor case finding project in the host community.
Methods
Directed by a representative county advisory council and supervised by a regional dean, clinical medical students designed and implemented CVD screenings at several public locations, recording health history and measurements of blood glucose, total blood cholesterol, and blood pressure. Those screened with abnormal readings were directed to definitive care including the local student-directed free clinic. Students were surveyed using a Likert scale before and after participation to assess their confidence in executing a community health project. The Baptist Health Madisonville IRB approved the protocol as exempt and the authors have no conflicts of interest.
Results
Over a period of almost two years in 2017-2019, 572 participants were screened. The demographics reflected those of the entire county, except screening was focused on adults. High blood pressure was found in 43%, high glucose in 28%, and high cholesterol in 48%. These values were similar to published countywide prevalence proportions. The student pre- to post- increase in confidence was remarkable (p< 0.000).
Conclusions
Our results show that regional campus medical students directed by a representative county advisory council and supervised by a regional dean can successfully implement a community CVD screening effort. The students also expressed a dramatic increase in their confidence in designing and implementing such a project. Lessons learned are shared for consideration by those at other regional health campuses.

Percepción de los estudiantes de la efectividad de los espacios colaborativos para disminuir las tensiones constitutivas en la enseñanza-aprendizaje de las Ciencias administrativas y contables
Authors: Díaz Mateus Rubén Darío , Sierra Morales Omar Andrés , Molina Roa Nelson Andrés
Published: December 2021

La historia de la educación en Colombia se configura por tensiones constitutivas producto de la relación contradictoria entre la tradición erudita renacentista, simbolizada por la universidad, y el surgimiento de la escuela pública, encargada de administrar y controlar. Una vez detectadas nuestras tensiones particulares, en la Facultad de Ciencias administrativas y Contables de la Universidad de La Salle, propusimos el uso de espacios colaborativos (learning environments)- didácticas fuera del aula- para disminuirlas. Este artículo indaga la percepción de nuestros estudiantes respecto a la efectividad de dichos espacios mediante una investigación cualitativa “participación-acción en educación” que analizó datos cuantitativos. Los resultados demostraron que ciertos espacios colaborativos alivianan las tensiones, pero otros no, por tanto, su diseño dependerá del propósito de la asignatura y las expectativas estudiantiles en el marco de la reflexión crítica.
Coronavirus Pedagogy in the Zoomoscape
Authors: Breen Marcus
Published: December 2021

The COVID-19 pandemic emptied universities, colleges, and schools across the United States in March 2020, forcing instructors into an unavoidable culture in which a networked commercial technology mediated teaching and learning. In the tradition of critical pedagogy, this article argues that students and instructors alike engaged through the artificial lenses and screens of Zoom. The “pinhole intimacy” of the Zoomscape is assessed using conscientization, the concept offered by the Brazilian educator Paulo Freire, to describe most pedagogy as an oppressive apparatus that can be overcome with direct engagement between students and instructors. In such an opticentric context, the Zoomosphere’s intimacy is used to explore how the emancipation proposed by conscientization might be applied to the culture of pedagogy in a college with a diverse student population, including pedagogical interventions to address the challenges associated with teaching Division I athletes. The context of a large communication department at Boston College provides the empirical foundation for the exploration of coronavirus pedagogy.

Published: December 2021

Introduction. This case of herpes virus–induced panniculitis originally diagnosed as pyoderma gangrenosum (PG) illustrates the need for a high index of suspicion for atypical causes of cutaneous ulcers in patients who are immunocompromised. Case Report. A 79-year-old male presented with a 3-month history of a painless chronic ulcer on the left buttock that was refractory to antibiotic therapy and intralesional corticosteroid. The medical history was notable for diabetes mellitus type 2 and rheumatoid arthritis managed with long-term methotrexate and low-dose prednisone. Because the patient initially had a painful and enlarging skin ulcer after intralesional treatment with corticosteroids, an undermined and violaceous ulcer, and an autoimmune condition, PG was suspected at the initial evaluation. A subsequent skin biopsy to complete the workup confirmed the unexpected diagnosis of herpetic panniculitis. The patient was started on antiviral therapy; a prolonged therapeutic and suppressive dose was required. This case highlights the importance of skin biopsy in the diagnosis of chronic ulcers to rule out infectious etiologies. Maintaining a high index of suspicion for rare causes of cutaneous ulcers in the patient with immunosuppression is paramount. Conclusions. Herpes virus infection is only one atypical cause of ulcerative nodules in the immunocompromised patient. Skin biopsy should be considered in the immunocompromised patient with presumed PG that is not responding to standard of care treatment.
Calculation of the Tafel slope and reaction order of the oxygen evolution reaction between pH 12 and pH 14 for the adsorbate mechanism
Authors: Antipin Denis , Risch Marcel
Published: December 2021

Despite numerous experimental and theoretical studies devoted to the oxygen evolution reaction, the mechanism of the OER on transition metal oxides remains controversial. This is in part owed to the ambiguity of electrochemical parameters of the mechanism such as the Tafel slope and reaction orders. We took the most commonly assumed adsorbate mechanism and calculated the Tafel slopes and reaction orders with respect to pH based on microkinetic analysis. We demonstrate that number of possible Tafel slopes strongly depends on a number of preceding steps and surface coverage. Furthermore, the Tafel slope becomes pH dependent when the coverage of intermediates changes with pH. These insights complicate the identification of a rate-limiting step by a single Tafel slope at a single pH. Yet, simulations of reaction orders complementary to Tafel slopes can solve some ambiguities to distinguish between possible rate-limiting steps. The most insightful information can be obtained from the low overpotential region of the Tafel plot. The simulations in this work provide clear guidelines to experimentalists for the identification of the limiting steps in the adsorbate mechanism using the observed values of the Tafel slope and reaction order in pH-dependent studies.

Maxwell Gerilme Tensör Yöntemini Kullanarak Anahtarlamalı Relüktans Motorun Hava Aralığı Uzunluğunun Radyal ve Teğetsel Kuvvetler Üzerindeki Etkisinin Belirlenmesi
Authors: YETGİN Asım Gökhan
Published: December 2021

Anahtarlamalı Relüktans Motorlar (ARM) son yıllarda endüstriyel uygulamalarda sıklıkla kullanılmaya başlanmıştır. Özellikle elektrikli araçlar ve evsel uygulamalar da karşımıza çıkmaktadır. ARM’ un bu kadar yaygın bir şekilde kullanılmaya başlamasına rağmen en büyük dezavantajlarından birisi de meydana gelen moment salınımlarıdır. Moment salınımlarını azaltmak için hem motorun tasarımı sırasında hem de motorun kontrol kısımlarında iyileştirmeler yapılarak azaltılmaya çalışılmaktadır. Momentin oluşmasında ise teğetsel kuvvet etkili olmaktadır. Bu sebeple bu yöndeki kuvvetin belirlenmesi ve analizi motorlar için büyük önem arz etmektedir. Bu çalışmada anahtarlamalı relüktans motorun hava aralığı uzunluk değerinin radyal ve teğetsel yöndeki kuvvet değerleri üzerine etkisi maxwell gerilme tensör yöntemi ile analiz edilmiştir. Optimal hava aralığı uzunluğu belirlenmeye çalışılmıştır. 550 W, 8/6 kutup sayılarında anahtarlamalı relüktans motor kullanılmıştır. Her bir motor modeline ait radyal ve teğetsel manyetik akı yoğunluğu değerleri ve kuvvet değerleri elde edilmiştir. Elde edilen sonuçlara göre hava aralığı uzunluğunun artması ile hem radyal hem de teğetsel kuvvet değerlerinde azalma meydana geldiği tespit edilmiştir.
