Published: October 2019

Aim/Purpose: This research aims to describe and demonstrate the results of an intervention through educational robotics to improve the computational thinking of student teachers.

Background: Educational robotics has been increasing in school classrooms for the development of computational thinking and digital competence. However, there is a lack of research on how to prepare future teachers of Kindergarten and Elementary School in the didactic use of computational thinking, as part of their necessary digital teaching competence.

Methodology: Following the Design-Based Research methodology, we designed an intervention with educational robots that includes unplugged, playing, making and remixing activities. Participating in this study were 114 Spanish university students of education.

Contribution: This research helps to improve the initial training of student teachers, especially in the field of educational robotics.

Findings: The student teachers consider themselves digital competent, especially in the dimensions related to social and multimedia aspects, and to a lesser extent in the technological dimension. The results obtained also confirm the effectiveness of the intervention through educational robotics in the development of computational thinking of these students, especially among male students.

Recommendations for Practitioners: Teacher trainers could introduce robotics following these steps: (1) initiation and unplugged activities, (2) gamified activities of initiation to the programming and test of the robots, (3) initiation activities to Scratch, and (4) design and resolution of a challenge.

Recommendation for Researchers: Researchers could examine how interventions with educational robots helps to improve the computational thinking of student teachers, and thoroughly analyze gender-differences.

Impact on Society: Computational thinking and robotics are one of the emerging educational trends. Despite the rise of this issue, there are still few investigations that systematize and collect evidence in this regard. This study allows to visualize an educational intervention that favors the development of the computational thinking of student teachers.

Future Research: Researchers could evaluate not only the computational thinking of student teachers, but also their didactics, their ability to teach or create didactic activities to develop computational thinking in their future students.

Students' perceptions regarding the use of ICT in learning
Authors: de Sousa Ana Elisa Carreta
Published: October 2019

This study focuses on how students of vocational courses related to Information and Communication Technologies (ICT) perceive the use they make of technologies in their learning. A questionnaire survey was applied in classroom to 314 students from 4 private and public schools, with the aim of understanding if the students recognize benefits in the use of ICT in teaching and learning, by answering the 34 premises presented to them. Most students recognize benefits from the use of ICT in teaching considering it improves and facilitates learning. They recognize the need to improve the pedagogical use of ICT and that teachers from the scientific and sociocultural components still make little use of the technologies in the classroom. These students consider that the courses they take prepare them to integrate the labor market, indicating good practices in learning with and from technologies in the technical classes. The premises about the disadvantages and obstacles resulting from the use of ICT were the ones that gathered the lowest consensus among students. They consider that the use of ICT is essential in learning and preparing to work with ICT and in a broader sense to live in a society of information and knowledge.

Musical education belongs to significant spheres of personality development and human expression. Music develops human imagination, enhances the emotional experience, evokes the human ability to perceive the organised world of sounds and stimulates the esthetical experience of this world. Many studies have shown that the importance of musical education is more important for primary school pupils than in later years. If before this age, in the families or schools the music education is not given enough attention, the child loses a lot (musical receptiveness, specific visual thinking), and later this kind of abilities for various reasons (disharmony of physical, emotional development, etc.) are more suppressed. Therefore, much of significance must be devoted to the musical education of future primary school teachers. The research data from qualitative and quantitative study analysis have highlighted the peculiarities of musical and pedagogical psychological competencies of primary school teachers.

The Effectiveness of Cooperative Integrated Reading and Composition (CIRC) Technique on Students’ Reading Comprehension
Authors: Nanda Dodi Widia
Published: October 2019

Reading comprehension has been considered as a major issue in the Indonesian EFL context including in the junior high schools. Whereas in fact, Indonesian junior high school students have been asked by the Indonesian Ministry of Education and Culture to understand various English texts effectively. Therefore, in an attempt to comply with the required criteria above, this paper proposes a possible solution to cope with Indonesian students’ reading comprehension issue. In this sense, CIRC proposed as a possible technique to enhance Indonesian junior high school students’ reading comprehension. Specifically, this research attempts to measure the effectiveness of CIRC technique on students’ reading comprehension at grade seven of a junior school located in West Sumatera, Indonesia namely the MTsN Koto Baru Junior High School. Accordingly, the study employed a quasi-experimental design, comparing students’ pre-test and post-test scores to measure the effectiveness of CIRC towards students’ reading comprehension. The different result between the pre-test and post-test tested using the paired sample t-test. It was found that students’ scores on pre-test (before treatment) was lower than post-test (after treatment). Thus, it can be inferred that CIRC was effective to increase students’ reading comprehension.

It is almost certain that the educational process cannot run without adequate financial support. Implications of policies the decentralization of education, making decision makers often having difficulty in getting references about components education funding. This need has been felt even more urgent since the start of the implementation of regional autonomy which also covers the field of education. Education costs are the economic value of inputs certain education that is used for learning to produce educational output of a certain level of education program. At the general level of financing concepts, costs can be in the form of expenses certain amount of money or certain sacrifice which is not in the form of money however it can be valued in money. Education costs are also the basis empirically to provide an overview of the school's financial characteristics. Analysis school financial efficiency in utilizing school financial resources and school output can be done by analyzing unit costs (units cost) per student. Unit costs per student are the average costs per student];calculated from the total school expenses divided by all students in the school (enrollment) in a certain period of time. By knowing the cost units per student by level and type of education are useful for assessing various alternative policies in an effort to improve the quality of education. The cost of education can be said to play an important role in sustainability of education. The success of an educational institution in organizing quality education is also inseparable from planning a steady budget, an allocation that is right on target and is effective so it makes all components of these educational institutions work together and produce results optimal in achieving goals. Educational institutions can also be closed as a producer of educational services, as is the case in other business fields face the same problem, namely the cost of production.

Authors: Kumar Rakesh
Published: October 2019

AbstractMagic and Medicine were intertwined in ancient civilization and are acutely embedded in folk healing culture currently. The Indigenous Knowledge (IK) of healing as cultural intangible heritage have been widely discussed by anthropologists, historians and fictional novelists. But within archaeological discourse, these practices have been neglected by the community of archaeologists. Here, the focus has been placed to the ethnoarchaeological investigation of the Black Magic (BM) practices of Mayong, Assam through the re-elucidation of its the material culture and symbolism used during Magico-Medicinal Practices (MMPs) or Magical Practices (MPs). Whereas, the fundamental objective is to critically review the existing archaeological as well as a socio-cultural approach to IK of Magico-Medicinal healing, in which MMPs and MPs have been diminished to the extent of social exclusion.

Authors: Kharkova O. K. , Soloviev A. G. , Odland J. O.
Published: October 2019

The aim of the study was to explore the personality of women with different smoking behavior during pregnancy using a biopsychosocial approach. Women aged 18-38 years who were hospitalized in the maternity hospitals of Arkhangelsk were enrolled to the study. Pregnant women were divided into three groups depending on the tobacco history: “smokers”, “quitters” and “non-smokers”. As a result of the study, we determined variation in social, biological and psychological components of the personality of women with different smoking behavior during pregnancy. Thus, quitting smoking during pregnancy was more common in married women, and those who had a non-smoking father of the child. Women who stopped smoking during first trimester in compared to smokers were more introverted, had more frequently an instinct of “self-preservation” and “research”. Values of euphoric type of psychological component of gestational dominant and self-esteem were higher among women who stopped smoking during pregnancy in compared to smokers. Smokers in compared to non-smokers had a lower social and economic status, were more often extroverted, emotionally unstable, rigid, less often had a strong development of the instinct «procreation», «research», «altruism», but more often «liberty». Moreover, smokers showed higher rates of depressive, anxious of psychological component of gestational dominant and weaker development of self-esteem and will. So, the revealed features demonstrate those targets to which preventive measures should be directed.

This work discusses the use of the ENEM ranking by a group of private schools in the city of São Paulo for commercial purposes and explcity through the data obtained from Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (INEP), how the families are led to look for these schools because of the disclosure of results with criteria and deficit of information, starting an "intellectual auction" for the search for scholarships to attend high school. It is well-known that the students' dispute between private schools in São Paulo has been fierce over the years and the transitions made by them tend to happen at the end of the last grade of Elementary School II (9th Year), so, after having done all training in an institution, in the final portion of their preparation, students tend to look for specialized entrance schools and better ranked in the ENEM. We observed that these elements end up distorting the real breadth of the school function that starts to adopt measures to keep its students and just prepare for the entrance exam.

Polymorphism is the ability of a specific chemical compound to crystallize in more than one crystalline form. Polymorphs had a different arrangement of the molecule in the given crystal lattice and  may properties such as packing properties, thermodynamic properties, spectroscopic properties, kinetic properties, surface properties and mechanical properties. Polymorph can be classified in various class such as crystalline, amorphous, hydrate and solvate. Polymorphs are categorized into two types, enantiotropes and monotropes, depending upon their stability with respect to the range of temperatures and pressures. There are various guidelines for the control of polymorphs in drug substances and drug product. Different analytical techniques are used for the detection, quantification and characterisation of the polymorphs in the drug substances and drug products. Control of polymorph in a drug substance and drug product is important for the safety and efficacy of the drug.

Vietnam’s environment protection tax: Possible impacts and incidence
Authors: Nguyen Van Chan , Coxhead Ian
Published: October 2019

This paper predicts economic and environmental impacts and incidence, in short term and in long tem, of the implementation of Law on Environment Protection Tax (EPT) recently promulgated by the National Assembly and coming into force by the beginning of 20121. The forecasts result from simulation scenarios run on an Applied General Equilibrium (AGE) model for the Vietnamese economy, using General Equilibrium Modeling Software (GEMPACK). Depending on the different assumptions about factors’ mobility, the numerical results of simulations show a relatively large short-run decline in the GDP growth rate, and smaller declines in the long run. In general, following the model results it seems difficult to expect that application of the EPT would directly bring positive economic effects2. The benefits of the EPT should be drawn from that the natural environment is improved and therefore the quality of life would be better. The simulation results also emphasize the necessity of gov- ernment accompanying policies and measures, such as use/ redistribute the EPT revenues in different programs aiming to improve the natural environment and to assist the strong- ly energy- dependent industries, to help the seriously suffering households. Our further research plan is precisely to run some model simulations on possible impacts of such kind of macro policies.
Vietnam rural financial market- Fact dianostics and the policy implications for rural development of Vietnam
Authors: Le Thanh Tam
Published: October 2019

The development of Vietnam rural sector has been given attention by different orientations and policy frameworks, of which rural finance is the key tool, notably the Decree 41 on cred- it for rural sector. The Vietnam rural financial sector has been growing and making significant contribution to its rural development by a rapid expansion of outreach and available fund sources. However, there have been remaining problems that are very likely to hinder the sector from its further development. Such problems are: (1) there is a lack of responsive and adequate financial services in rural areas; (2) a significant number of the poor households still do not have access to any microfinance services, to name a few. Thus, this paper is intented to focus on two main issues. The first is to analyze the causes of such problems, and the second is to pro- vide recommendations that are strongly expected to overcome such problems to enhance Vietnam rural development in the new decade with the Development Millenium Goal.

Retailer’s Perspective of Product Brand Equity: An Empirical Study of Vietnamese Independent Drink Stores
Authors: Hoang Thi Thu Huong , Yu-Li Lin
Published: October 2019

In the literature on product branding, significant attention has been paid to brand equity in the consumer context, but relatively little attention has been paid to the application of the concept of brand equity in the business-to-business context. This research attempts to bridge this gap by exploring the customer-based brand equity concept from the retailers’ perspective. The study was conducted in the context of the Vietnamese independent retail grocery sector. This context was chosen on the basis that there has been limited research conducted on branding in the Vietnamese context and due to the prominence of the independent grocery sector in the retail industry of Viet Nam. By using AMOS 16 and SPSS 16.0 software, the results of the study indicate that brand equity plays an important role in the retailing context, and it comprises three dimensions - brand association, brand trust and brand loyalty. As the result of a strong brand, retailers commit to a long-term business relationship with the brand’s manufacturer. Two of these three dimensions of retailer-based brand equity, (brand association and brand trust) are positively and significantly related to the brand’s performance at the retail outlet. Manufacturer support, including advertising, sales promotion and trade promotions has been confirmed by this study to be an antecedent of retailer-based brand equity, brand performance and customer perceived value as well.

Key experimental studies (mainly pulse heating) aimed at obtaining the physical properties of the most refractory substance — graphite — in the temperature range of 2000–8000 K are discussed. The properties considered are enthalpy, input (Joule) energy, thermal expansion, specific heat, and electrical resistance, as well as their dependence on the level of applied pressure. The results obtained by pulsed current heating and laser pulse heating are compared. An abnormally high specific heat just before the melting point is recorded under fast (during microseconds) heating of graphite. These effects are presumably associated with the appearance of nonequilibrium defects. A connection between these anomalies and the explosive electron emission is noted.

Electrical energy is energy derived from electric charge that causes static electric field or the movement of electrons in a conductor (conductor of electricity) or ions (positive or negative) in a liquid or gas. The electrical energy needed by society to lighting, heating, cooling, or to move back in mechanical equipment to produce other forms of energy. Utilization of a mixture of sand and sea water is one of the methods of renewable energy. In other hand, utilization of sea water is known that it can generate electricity. This study is a preliminary study to combine sea water and sea sand as raw materials. The purpose of this study was to analyze the optimal composition of sea water and sea sand in generating electrical energy. Source of sea water and sea sand comes from Kenjeran Beach Surabaya Indonesia. Research methods such as mixing sea water and sea sand with a weight percent ratio sea sand in the mixture of 0%, 25%, 50%, 75%, and 100%. The electrical energy generated is determined by observing the current flow and power are seen on the multi meter. Based on the results of current and voltage measurements obtained respectively 2,4 V; 2,3 V; 2,3 V; 1,8 V; and 0,9 V. So the results of the analysis of the composition of sea water and sea sand can potentially be used as a source of electrical energy, although sea sand as agent of resistant.

Surfactant is a surface active agent which is widely applied in chemical industry related to its ability to stabilize the emulsion between the oil phase and the water phase. Surfactant-based on vegetable oil is a technology developed in the field of surfactant which has been dominated by surfactants made from petroleum. Methyl ester sulfonate (MES) is an anionic surfactant produced by the reaction between fatty acid methyl ester with a sulfonating agent or called as sulfonation reaction. MES undergoes an advanced process called methanolysis and neutralization reactions. This study investigated the effect of reactant molar ratio, reaction time and reaction temperature on MES yield on methanolysis reaction. The highest MES yield of 49.71% was achieved at a reaction temperature of 120°C, the reaction time of 120 minutes and the molar ratio between MES and methanol of 1:3. The rate constants of methanolysis reactions are determined by reacting the reactants in the stirred batch reactor under those operating conditions.

Selama ini silica fume dikenal sebagai bahan campuran pembuatan beton karena dapat meningkatkan kuat tekan beton, menurunkan permeabilitas beton dan memiliki ketahanan sulfat yang tinggi. Dalam penelitian ini mencoba mengaplikasikan silica fume pada pembuatan durable cement. Silica fume dijadikan sebagai bahan pozzolan karena didalamnya mengandung silica tinggi yang bersifat reaktif agar dapat meningkatkan ketahanan terhadap sulfat. Bahan pozzolan ini dapat bereaksi dengan Ca(OH)2 pada suhu biasa untuk membentuk senyawa bersifat semen. Pada penelitian ini silica fume divariasikan mulai dari 0; 7,5; 15; 22,5; 30; 37,5%. Durable cement ini akan diuji ketahanan sulfatnya dengan menggunakan metode pengujian kuat tekan. Hasil percobaan menunjukkan terjadinya penururan nilai kuat tekan sampel pada umur 7 dan 28 hari jika dibandingkan dengan blanko. Hal ini disebabkan lambatnya reaksi pozzolan (silica fume). Namun proses peningkatan kuat tekannya akan terus berlanjut hingga setelah umur 360 hari. Jika dibandingkan dengan Standar Nasional Indonesia (15-0302-2004) semen PPC tipe IP-K, hasil sampel durable cement masih memenuhi standar untuk variabel dengan penambahan silica fume antara 7,5% sampai 22,5%.

Silica fume is known as a mixture of concrete manufacturing since it can increase the compressive strength of concrete, decrease the permeability of concrete and have a high resistance to sulfates. In this research, try applying silica fume to make durable cement. Silica fume is converted to pozzolan because it contains highly reactive silica to increase sulfate resistance. This pozzolan material can react with Ca (OH)2 at a room temperature to form a cement compound. In this study, silica fume was varied from 0; 7.5; 15; 22.5; 30; 37.5%. The durable cement will be tested for its resistance to sulfates by using a compression resistance test method. The results showed that the compressive strength of the sample was decreased at 7 and 28 days compared to the blanks. This is due to the slow reaction of pozzolan (silica fume). But the process of increasing the resistance to compression will continue until after 360 days. Compared with Indonesia cement national standard (15-0302-2004) of PPC type IP-K, the durable cement sample still meets the standard for variables with the addition of silica fume between 7.5% and 22.5%.

Abstract
This study investigated the effect of formalin inhalation on visual acuity of medical students in Madonna University, Elele, Nigeria. Two hundred students (100 males and 100 females) between the ages of 16 and 25 years participated in the research. Students were grouped into two of 100 students per group (50 males and 50 females). Group A is the control, non-exposed group while group B is the test group exposed to formalin inhalation. Data collection among the randomly selected students involved a combination of self-administered and interviewer- administered questionnaires. Visual acuity test was done for distant (DV) and near (NV) visions using the Snellen’s chart and Jaeger’s chart respectively. Results of visual acuity of non-exposed and formalin-exposed male participants showed impairment in 20% and 48% of respectively for DV; 22% and 64% respectively for NV. The percentage of visual impairment in non exposed and exposed female participants was 18% and 42% respectively for DV; 24% and 26% respectively for NV. In conclusion, this study revealed a statistical significant decrease in visual acuity among medical students exposed to formalin inhalation compared to the non-exposed students. Visual impairment was more in males than in females. It is therefore recommended that the concentration of formalin in formalin-treated cadavers used by medical students be re-evaluated and proper ventilation in dissecting rooms/halls be ensured to avoid exposures to abnormally high concentrations of formaldehyde.
