  • The dataset was constructed to examine Vietnamese student’s learning habit during the school suspension time due to the novel coronavirus - SARS-CoV-2 (Covid-19), responds to the call of open research to prevent potential effects of coronavirus (Elsevier, 2020). The questionnaires were spread over a network of educational communities on Facebook from 7th to 28th of February 2020. Using the snowball sampling method, researchers delivered the survey to teachers and parents to confirm the consent form before they forward it to their students and children. In order to measure the influence of student’s socioeconomic status and occupational aspirations over their learning habit during school closure, the survey includes three major groups of questions: (1) Individual demographic, includes family socioeconomic status, school types, and occupational aspirations; (2) Student’s learning habits, include hours of learning before and during school suspension time, with and without other people’s support; and (3) Student’s perception on self-learning during the disease. There was a total of 920 clicks on the survey link, but only 460 responses with consent form were received. The incurable answers (e.g., year of birth is before 2009, more than 20 hours of learning per day, etc.) have been eliminated. Finally, the dataset includes 420 valid observations.

  • As seguintes hipóteses foram testadas: H1: MILITARES MAIS MOTIVADOS COM A INSTITUIÇÃO TÊM MENOR INTENÇÃO DE ROTATIVIDADE H2: MILITARES IDENTIFICADOS MAIS FAVORAVELMENTE COM A INSTITUIÇÃO TÊM MENOR INTENÇÃO DE ROTATIVIDADE. Para a análise dos dados coletados a partir do questionário anexado, foram utilizadas análises estatísticas descritivas e inferenciais, sendo estas últimas fundamentadas na análise fatorial, teste de correlação, regressão linear múltipla e Teste t. A amostra final foi composta por 388 militares da área finalística e de apoio de uma instituição das Forças Armadas. Os resultados mostraram que a motivação não mostrou relação significativa com a intenção de rotatividade, tendo sido apenas a identificação organizacional confirmada como variável preditora.

  • This study aims to discuss how teaching and learning activities were carried out by using Genre-based in teaching English grammar in constructing sentences at SMA Negeri 1 Kota Ternate. This study was conducted to the 27 students of class XI language and culture. The research was designed into a qualitative approach by using the phenomenological method. To collect data, the researcher used the students' results of the test. Research findings reveal that more than 70% of the students were successful in identifying the language features of constructing sentences. The implementation of a genre-based approach to teaching English grammar gives a good contribution to the improvement of the students' proficiency in constructing sentences.

  • Here we present the first demonstration of the use of eggshell membrane for research on endangered Maleo (Macrocephalon maleo). We used 24 post-hatched eggshell membranes collected from two different sites, Tambun and Tanjung Binerean, in North Sulawesi, 12 samples in each. Two different DNA extraction methods: alkaline lysis method and gSYNCTM DNA Extraction Kit were applied. To determine the sex of Maleo, we utilized PCR-based DN A sexing using CHD genes, with the primer set 2550F/2718R. We successfully extracted all samples; mean sample concentration was 267.5 ng/µl (range 47–510.5 ng/µl) and samples were of high purity (A 260/280 ratio 1.85±0.03). All samples were used to successfully identified sexes, 9 females and 15 males. Our research clearly illustrates that eggshell membranes can be used for DNA sexing and open the possibility to build noninvasive DNA collections over large spatial scales for population study of endangered birds. The data consist of A. Electrophoresis photos of (1). DNA extraction of Maleo from eggshell membrane, collected from Tambun and Tanjung Binerean, North Sulawesi, from 4th April until 1st May 2018. We used gSYNCTM DNA Extraction Kit (Genaid) followed the provided user manual with little modifications to isolate the DNA frm the eggshell membrane. The eluded DNA (1 µl) was quantified using NanoVue Plus™ (Biochrom, Harvard Bioscience, Inc), at A260 nm. The 260/280 nm absorbance ratio was measured to give an indication of purity of the DNA. (2). PCR products of molecular sexing, using lysate and extracted DNA. We applied PCR based DNA sexing by using CHD genes, with the primer set 2550F/2718R (28). PCR used a 10 µl total volume containing template DNA (genomic DNA or lysate), 1.2 µl sterile dH2O, 5 µl 2x PCR buffer KOD FX Neo, 2 µl dNTPs (2 mM), (TOYOBO Co. Ltd.), 0.3 µl Primer 2550F (10 µM; 5'-GTT ACT GAT TCG TCT ACG AGA-3'), and 0.3 µl Primer 2718R (10 µM; 5'-ATT GAA ATG ATC CAG TGC TTG-3', (28)), and 0.2 U KOD polymerase enzyme. PCR was carried out in a Veriti™ 96-well thermal cycler (Applied Biosystems™). For genomic DNA templates, the following profile was used: 1 cycle at 94℃ for 2 min followed by 35 cycles of 98℃ for 10 sec, 53℃ for 30 sec and 68℃ for 45 sec;, and a final extension at 68℃ for 7 minutes. For lysate as DNA template, the PCR profiles was the same for DNA genome, except that it was run for more cycles (40x). B. Sequences of CHD-W and CHD-Z genes of Maleo The electrophoresis gels were cut on upper and lower bands for female sample and single band for male sample, then purified for sequencing. The sequence reactions were carried for both direction in sequencing services laboratory provided by 1st BASE Laboratories (Apical Scientific Sdn Bhd), Malaysia.

  • The construction industry is a large sector of the global economy and provides many jobs. Due to the nature of the industry, the workers are at a high-risk for an injury or a fatality. Construction safety training can teach workers how to avoid hazards and increase their risk perception, but current instruction methods do not seem to be lowering the rate of incident with fatality rates staying consistent throughout the years with the main cause of incident being human error. To improve current training methods and increase overall risk perception in construction workers, this paper aims to investigate different methods of conventional safety training and various techniques for measuring the effectiveness of safety training and propose approaches to improve typical construction safety training modules. The application of Virtual and Augmented reality in construction safety training is explored in this paper as well as the current methods used to train construction workers about safety. In this paper information was gathered in order to address different feedback as indicators of a worker’s risk perception.
