Pre-service teacher’s mathematical knowledge for teaching in problem-based learning
Authors: Novikasari Ifada 
Published: June 2020

Mathematical Knowledge for Teaching (MKT), comprising Mathematics Content Knowledge (MCK) and Mathematics Pedagogy Content Knowledge (MPCK), is essential for pre-service teachers. However, numerous studies have shown that pre-service teachers are weak in content and difficult to plan to teach. Therefore, a shifting effort dealing with the learning activities within the teacher training program from a teacher-centered to student-centered approach should be made. One learning model succeeding in the student-centered approach is Problem-Based Learning (PBL). Studies on PBL as an effort to improve the MCK and MPCK of pre-service teachers have never been done before. There were two models of PBL applied in this experimental study: PBL with authentic problems (PBL1) and PBL with authentic problems and teaching practices (PBL2). The aspects of MCK studied are knowing, applying, and reasoning. While the aspects of MPCK are creating representation for the explanation, understanding mathematical structures, and anticipating students' thinking. The results of the study showed that there were significant differences between MCK and MPCK achievements in PBL1, PBL2, and conventional learning classes conventional. PBL1 and PBL2 classes were considered superiors since the pre-service teachers predominantly control the learning activities and were active in finding solutions. Hence, there were differences in the effect of the learning models on the aspects of MCK and MPCK.
The pattern of a relational understanding of fifth-grade students on integer operations
Authors: Utomo Dwi Priyo 
Published: June 2020

Relational understanding constitutes students’ awareness of appropriate procedures to solve problems along with logical reasoning. Itis pivotal to help students solve problems in mathematics. It is necessary that the teaching of mathematics be directed to achieve relational understanding. Accordingly, students are capable of solving complicated problems in mathematics. This current research aims at analyzing and describing relational understanding and the patterns of answering questions of the fifth graders on integer operation. This study used a qualitative approach with a case study as the research design. Further, three students belonging to the fifth grade of Elementary School in Malang City, Indonesia, were set up as the research subjects. A test was administered to measure the subjects' relational understanding. All collected data were analyzed using an interactive technique. The result has indicated that the highly-proficient student was able to show excellent relational understanding. Besides, it was shown that the fairly-proficient student could show good relational understanding. The lowly-proficient student was shown to be able to achieve only half of the holistic criteria set for relational understanding. The patterns of answering the questions demonstrated by all students in all levels included jotting down the models, completing the models, and answering the questions. The highly-proficient student understood the information and wrote it down. Whilst the fairly-proficient student understood the information without translating it into the written form. At last, the lowly-proficient student did not pronounce any signals of understanding of the information

Antibacterial effect of the ethanol, methanol and ethyl acetate extracts of Piliostigma reticulatum and Cleistopholis patens on ten pathogenic bacteria including Pseudomonas aeruginosa, Salmonella typhi, Escherichia coli, Proteus vulgaris, Streptococcus pyogenes, Klebsiella aerogenes, Staphylococcus aureus, Serratia marscences, Yersinia enterocolitica and Shigella dysenteriae was investigated. Survival rate after treatment was investigated. Cell surface hydrophobicity after treatment was tested and the catalase activities of the plant extracts were determined. The results revealed that at 100mg/ml of extracts, the ethanol extracts of C. patens showed antibacterial activities against S. typhi, P. vulgaris, Str. pyogenes, K. aerogenes, Saureus and Yersinia enterocolitica with zones of inhibition of 18mm, 14mm, 18mm, 24mm, 14mm and 18mm respectively and the ethyl acetate extract was active against Sal. typhi, P. vulgaris, Str. pyogenes, K. aerogenes, S. aureus Ser. marscences and Y. enterocolitica with zones of inhibition of 14mm, 22mm, 18mm, 18mm, 14mm, 16mm and 16mm respectively while ethanol extract of P. reticulatum showed activity against P. aeruginosa, Sal. typhi, E.coli, Str. pyogenes, K. aerogenes, S. aureus, and Sh. dysenteriae with zones of inhibition of 13mm, 12mm, 10mm, 10mm, 8mm, 10mm and 14mm respectively. The ethyl acetate was active against E.coli, Str. pyogenes, K. aerogenes, S. aureus and Sh. dysenteriae respectively. The methanol extract had no activity against the test organisms. The kill- time curve showed that susceptible cells die after 10 and 20minutes after contact with the extracts of C. patens for most of the test bacteria while cell death occurred at 10, 20, 40, 50 and 60 min after contact. The hydrophobicity test showed that test organisms had hydrophobicity of between 47% and 99% in the extracts. Catalase production reduced considerably in some bacteria after treatment with plant extracts. The results obtained presupposes that the plant extracts are effective against some of the test organisms and their mode of activity are is that they interfere with the ability of bacteria to produce catalase, inducing cell death by the production of hydroxyl radical and also by to the enhancement of non-opsonic phagocytosis of bacteria by macrophages.

Published: June 2020

Background: The burden of cardiovascular diseases in developing countries such as Nigeria is worsened by the increasing prevalence of cardiovascular risk factors. This study is aimed at assessing the levels of cardiovascular risk markers in young Nigerian adults who are hyperglycemic at baseline.
Material and Methods: A total of 200 participants (male and female), aged 15-35 years initially took part in the study while the data of 61 participants (44.3% male and 55.7% female) who were hyperglycemic at baseline was analyzed using Statistical Package for the Social Sciences (SPSS) version 23.0. The levels of cardiovascular risk markers were analyzed in these hyperglycemic young adults.
Results: The females in the study population had a higher blood glucose level (102.91 ± 9.68) when compared to males (98.81 ± 8.13). The study reported the prevalence rates for cardiovascular risk markers: hypertension [31.15% (male), 14.70% (female)]; overweight and obesity [33.33% (males), 52.94% (females)]; central obesity [14.81% (males), 64.70% (females)]; high waist-to-hip ratio [33.33% (males), 91.18% (females)]; hypercholesterolemia and low LDL-C [37.04% and 33.33% respectively (males), 67.65% and 61.76% respectively (females)]; hypertriglyceridemia [25.92% (males), 17.60% (females)]; high atherogenic index of plasma [25.92% (males), 14.70% (females)]; elevated C-reactive protein [7.41% (males), 8.82% (females)]. The cardiovascular risk markers were more prevalent in females relative to the males.
Conclusions: The high prevalence of cardiovascular risk markers suggests that most apparently healthy Nigerians, including young adults may be at high risk of developing cardiovascular diseases.

Published: June 2020

In Algeria, the debate on the role of higher education is flourishing; it is very much concerned with meeting the needs of the labor market, youth unemployment rates, and promoting knowledge transfer between university and industry.
Our study offered an overview of higher education system in Algeria, and tried to evaluate the influence of entrepreneurship courses taken at university and outside it on supporting student entrepreneurial intention.
This study was applied at the faculties of Business and Economics, in three Algerian universities, from November 2019 to January 2020, on a sample of 293 comprised students of the 1st to 3rd year.
By conducting the ASTEE questionnaire which contained 57 questions covering multiple dimensions including demographic questions, we confirmed that there were significant differences in all dimensions between Algerian entrepreneurially educated students and European entrepreneurially also non-entrepreneurially educated respondents, which explain the crucial role of university in promoting entrepreneurship. Our results affirmed that, unlike males, females tend to be innovative employees than being entrepreneurs.
Despite of the satisfactory result, Algeria is invited to be keener in the use of modern methods and in the use of specialized frameworks in teaching entrepreneurship, In addition Algeria should pay more concern to generalize entrepreneurial education in other specializations of university.

Published: June 2020

This study set out to analyze the effect of innovation on firm performance in developing economies in the era of trade liberalization. The study uses data from the enterprise survey of the World Bank covering 19 Sub Saharan African countries surveyed between 2014 and 2016, with a total of 8,551 firms included. In order to effectively analyze the effect of innovation on firm performance, the CDM model is adopted to analyze R&D intensity, the effect of domestic R&D on innovation output, and the contribution of innovation to firm performance in the sub region. The study further tests for the effect of foreign technology and the import of products and services on the innovation process. Analysis is done using ordinary least squares. Findings suggest a positive and significant effect of foreign technology on domestic R&D, while imports have a negative effect on domestic R&D. Domestic R&D has positive effect on both product and process innovations among firms in the sub region. Moreover, both product and process innovations have a positive and significant effect on firm performance in the sub region. Meanwhile, the export of innovations is not found to be significant in this study. We therefore recommend that governments in the region should give tax incentives to organizations that import products that are meant specifically for the production of new products and processes. Firms in the sub region should also focus on narrow market segments where they have specialist expertise in, so as to be competitive in the global market.
Digitization in the German Health Care System - An Analysis of the Status Quo Using the Example of the Dental Sector
Authors: Maier Christian , Juschkat Tizian 
Published: June 2020

According to the Federal Ministry of Economics and Energy, the German healthcare industry is growing faster than the economy as a whole but is regularly far behind compared to the rate of digitalization. Nonetheless, the healthcare industry offers great potential for digital applications. The brief overview at hand uses the example of treatment and cost plans in the dental field to illustrate the state of digitalization in the German health care system.
The primary goal is to examine whether it is possible to transfer the principle of electronic data medium exchange for hospital settlements and the associated electronic data processing to the transmission of treatment and cost plans in the dental field. Anselstetter's (1984) expertise is fundamentally used to evaluate the benefits of electronic data processing and to a treatment and cost plan under critical evaluation. In order to determine relevant benefit effects for health insurance funds and dentists, a transfer and processing form of the treatment and cost plan is used based on a generated model.
Applying this model can assist health insurance funds to identify effects regarding time, personnel reduction, and more efficient use of existing personnel structures. It also provides health insurance companies and dentists with an overview of the possible benefits of electronic data transmission and processing. Nonetheless, one of the problems is that it is not possible to calculate the expected costs due to the lack of empirical examinations. Consequently, a detailed cost- benefit evaluation of an electronic transmission and processing of the treatment and cost plans is unfeasible.

Published: June 2020

The process of research, development and innovation (RD&I) is very important for the technological growth of a nation. Because they are activities with a considerable level of uncertainty, they require a lot of planning, with the execution of projects and a robust risk management. In the Western Amazon is one of the largest industrial parks in Brazil, subsidized by tax benefits from Law No. 8,387 / 1991, which also establishes the obligation for companies that manufacture computer goods to allocate part of their revenue for the implementation of projects of Research and Development. Studies show that the results of RD&I activities carried out in the Western Amazon, as well as in Brazil, are deficient. Thus, this work aimed to present a risk management model that can contribute to a better management of processes related to RD&I in the Western Amazon. The methodology consisted of a scientific research of applied nature, whose data were collected through bibliographic, documentary and case study research, and later they were analyzed in a qualitative way. It was concluded that the risk management model presented here is a practical manual composed of a detailed procedural rite of great value for managers who want to implement a risk management program in their organizations and, specifically in the case of SUFRAMA, represents a support instrument to guide the management of risks inherent to RD&I activities developed in the Western Amazon, enhancing its results and contributing to expand the technological development of the region.
