Authors: Salaamah Ainul Fatayaatis , Fathani Teuku Faisal , Wilopo Wahyu
Published: August 2019

One important part of rock mass investigation is the geomechanical assessment in terms of rock mass classification systems. Rock mass classification is one of themost efficient methods in rock mechanics to provide a basic understanding of rock masscharacterization. Rock mass properties can be determined by a seismic refraction surveyas an indirect geophysical assessment. In this study, the P-wave velocity from seismicrefraction was compared with the Rock Quality Designation (RQD) from the boreholes.The empirical correlation between the RQD and the P-wave velocity was found by usingthe linear regression analysis. The RQD value estimated from the P-wave velocity can beapplied for tropical environment study with geological conditions of volcanic rocks. This study helps to estimate and predict the subsurface rock quality, to reduce investigation costs, and to improve understanding of subsurface rock quality.

Published: August 2019

This study aims at examining the agreement level between clinical diagnoses by a senior psychologist in the hospital and diagnoses/screening on Strengths and Difficulties Questionnaire conducted by parents. Using ICD 10 (Indonesian version) as the gold standard, a clinical child psychologist diagnosed 253 male and female elementary school children aged 7-14 years old. Parents of the same children were requested to fill-out the SDQ questionnaire (SDQ-PR).  Psychometric property of SDQ-PR was analyzed using Alpha Cronbach and Principal Axis Factoring Analysis. Screening quality of SDQ-PR was examined using Receiver Operating Characteristic (ROC), Likelihood Ratio (LR+ and LR-), and Chi-square. Reliabilities of SDQ-PR in all subscales were (α = 0.562 to α = 0.684) except subscale of peer-problem (α = 0.174). Different from the original version of SDQ-PR that consists of 5 subscales, this study revealed 8 subscales. LR and ROC analyses for hyperkinetic revealed LR+ = 1.84 and LR– = 0.51, sensitivity = 67.6% and specificity = 63.3% with cut-off score ≥ 6. For behavior disorder, the LR+ = 2.3, LR- = 0.42, sensitivity = 70.96%, and specificity = 69.15% with cut-off score ≥ 4. As for behavior disorder the LR+ = 1.07, LR- = 0.94, sensitivity = 50%, specificity 53.27% with cut-off score ≥ 4. Chi-square score indicated a significant correlation between SDQ-PR and the diagnoses from child psychologist for hyperkinetic and behavior disorder, but not for an emotional problem.

Published: August 2019

Until now, no literature exists to explain about the impact of time, and environmental parameters, when using typical commercial grade transparent linear low density polyethylene (LLDPE) packaging for protecting vegetable cooking oil during typical shelf-life conditions. We tested long-term impact of temperature and illuminance (light: 100 to 150 lux and darkness <1 lux) on refined bleached deodorized palm olein (RBDPOL), fortified with vitamin A. Results showed degradation of fortified RBDPOL with 70 ppm vitamin A was  approximately 15% at 18-22oC in Light, 10% at 18-22oC in Darkness, 19% at 32-33oC in light and 17% 32-33oC in darkness. Similar trend was observed at 45 ppm vitamin A. Exposure to heat and light impacted vitamin A degradation, but is primarily attributed to temperature, irrespective of packaging. This investigation builds on our previous work (Silalahi et al., 2017), and confirms the impact of challenging environmental conditions on vegetable cooking oil shelf-life over long time periods.
Livro Didático de Ensino Médio, Geometria e a Presença das Tecnologias
Authors: Barcelos Amaral-Schio Rúbia
Published: August 2019

O presente texto é fruto de uma pesquisa em andamento, que dentre seus objetivos está a análise da integração das tecnologias aos livros didáticos de Matemática. A pesquisa é de cunho qualitativo e visa instigar a reflexão sobre as contribuições de diferentes recursos didáticos (tecnologias digitais em particular) às práticas dos professores com livros didáticos. Neste artigo o foco é apresentar parte dos resultados, advindos da análise de atividades de cinco coleções de livros didáticos do Ensino Médio no âmbito das propostas de uso das tecnologias no desenvolvimento de conteúdos de Geometria. Os resultados apontam a pouca presença das tecnologias digitais nos livros do Ensino Médio, sendo raras as atividades que apresentam questões de investigação, de exploração visual de figuras geométricas, e de utilização de softwares de geometria dinâmica, que abordam aspectos do dinamismo desse recurso. A maioria delas se limita à realização e conferência de cálculos. Espera-se que haja uma mudança desse quadro, uma vez que desde 2014 Objetos Educacionais Digitais têm sido incorporados aos livros didáticos, com a proposta de haver uma maior integração das tecnologias ao tradicional recurso impresso que o professor usa para desenvolvimento de suas aulas.

Authors: Natan Paschoal Leo , R. S. Souza Simone
Published: August 2019

Em geral, os alunos de Computação não estão motivados para aprender testede software. Eles preferem aprender programação em oposição a aprender a testar um programa. Diante disso, estudos mencionaram sobre investir em outros modelos pedagógicos, a fim de tornar o aprendizado mais atraente. O Flipped Classroom surge como uma proposta interessante, pois concentra-se no uso da sala de aula para a construção de conhecimento e não apenas para a transmissão de informações. No entanto, a adotação do modelo exige esforços por parte do professor, porque ele precisa preparar um conjunto de atividades a serem aplicadas eficientemente nos três momentos deste modelo. Além disso, o professor precisará estabalecer um conjunto de mecanismos de apoio a serem utilizados pelos alunos durante o ensino. A fim de contribuir para o ensino de teste de software, este artigo apresenta uma abordagem para apoiar o planejamento e a aplicação da Flipped Classroom para este domínio de ensino. Também são apresentados os resultados da aplicação da abordagem em uma aula de Engenharia de Software. Com base nos resultados, as lições aprendidas e as perspectivas futuras são apresentadas e discutidas.

Avant-garde as a General Cultural Phenomenon in the Dynamics of European Spiritual Life: a Philosophical Analysis
Authors: Tarasov Aleksey Nikolaevich ,   Lipetsk State Pedagogical University
Published: August 2019

The study discusses the avant-garde of the last third of the 19th – early 20th centuries as a general cultural phenomenon of European spiritual life. In the author’s opinion, it embodied such dominant cultural characteristics of transitional epochs as relativism, skepticism, eclecticism, pluralism, gamification, the break with the previous cultural tradition. From the perspective of Russian humanities, the avant-garde was traditionally interpreted as a phenomenon related to the art. The author analyzes the development of science, religion, and philosophy at the turn of the 19th-20th centuries. Like art, these spheres are characterized by the new phenomena that have guided their development during the transitional period under consideration. The study reveals the reasons for the occurrence of the avant-garde and its manifestations in four spheres of culture: art, science, religion, and philosophy. Each of them reflected the social and cultural transformation in its own way. The study shows the importance of the avant-garde phenomenon for European (Euro-Atlantic) cultural dynamics in general.
The Development of Students’ Figurative Thinking When Learning Lyrical Landscape
Authors:   Murmansk Arctic State University, Lagutina Olga Rudolfovna
Published: August 2019

The paper traces the origin of Russian lyrical land-scape that evokes innermost poetic emotions and love for the motherland. While analyzing ways of perceiving picturesque landscapes, the au-thor focuses on the culture of feelings, experiences, and aesthetic judgments. The research discusses the problem of finding a unified approach by different sciences and related fields (phi-losophy, psychology, education, techniques, art studies) that explain figurative thinking differently. However, researchers have failed to conduct a sys-tematic analysis of figurative-thinking development practices. The study summarizes the theoretical and practical approaches to develop-ing figurative thinking in primary and secondary school students during classroom landscape-painting conversations, plein air workshops, and narrative art classes. The research substantiates the applicability of a system of methods (based on the active theory of P.Ya. Galperin, L.V. Zankov, V.V. Davydov, D.B. Elkonin). This makes it possible for students to convey mood and feelings in land-scapes by means of artistic expression (color, flavor) that demonstrate the degree of figurative thinking development.

Many companies emphasize on the efficiency of employees, thus, organizations have been seeking for the methods that can improve the employees’ performance and efficiency. Organizational citizenship behavior (OCB) has been recognized as one of the significant factors that can enhance the organizational efficiency and overall productivity. Among the variables that could affect the level of OCB, the differences of genders on OCB should be concerned. This is because different genders of perceptions could influence employees’ behaviors in organizations. Hence, it is crucial to examine the significance of gender differences in OCB among employees. However, limited studies were conducted to investigate the significance of the gender differences in OCB. Hence, this paper intends to minimize the research gap by examining the significance of genders’ difference, as well as determining the level of OCB among the genders. A total of 85 valid respondents from few Malaysian manufacturing companies participated in this research. The results revealed that there is no significant genders’ difference on both dimensions of OCB, namely OCBI and OCBO. No significant genders’ difference was found in overall OCB as well. Future studies are recommended to conduct more studies on larger sample size, as well as to conduct their studies on wider scope of respondents.

Authors: Sosna Ireneusz
Published: August 2019

Choice of orchard system is one of the major factors, on which pear crop size and quality depend. The purpose of this research was to assess the influence of two training systems involving trees trained to different number of leaders on growth, yield, and fruit quality of three pear cultivars. The study was conducted in 2001–2012 near Wrocław (south-western Poland). One-year-old trees of ‘Carola’, ‘Dicolor’ and ‘Erika’ cultivars on the Quince S1 rootstock were planted in the spring 2001 using 3.5 m between rows and a variable in-row spacing: 1.7 m (Drilling form with 3 leaders) and 1.2 m (Güttingen – V system with 1 leader). More vigorous growth was observed from more sparsely planted trees under the Drilling form. The total per-tree yield during 2002–2012 was decreasing as the planting density increased. No differences were observed on yield per hectare between the tested systems. The Drilling trees produced significantly heavier and larger fruit than the trees trained to the V-Güttingen system.

Root vegetables have greater risk of metal contamination from compost application to soil than other horticultural crops. Moreover, soil organic amendments pose potential environmental hazards. The objective of the present study was to examine the heavy metal uptake in different tissues (petiole, blade, skin, pulp) of Raphanus sativus exposed to organic amendments doses. The impact of the above materials on heavy metal concentration of the soil and plant development parameters were also evaluated. A pot experiment was established with eight treatments arranged in a randomized complete block design and four replicates. Co-compost of sewage sludge and olive wastes at 100, 200, 300 m3 ha–1, composted olive leaves, olive tree pruning wastes, olive mill pomace and poultry manure at 100, 200 m3 ha–1, commercial liquid organic fertilizer at 50 Kg ha–1 with or without inorganic NPK fertilization and a no fertilizing control, were applied to plants. The results showed that sewage sludge application strongly increased the yield and improved radish size cultivated in silt loam soil. The edible radish part had the lowest Fe, Mn, Cu, Zn, and Cr content, whereas the highest Mn, Cu, Zn, Cr was found in the blade and increased Fe, Ni, Pb were recorded in the skin. Organic treatments gave higher Fe, Mn, Cu, Zn amount in both aerial plant tissues compared to the control soil, while Ni, Pb, Cr of all the radish parts were not affected by treatments. This study suggested that organic amendments application gave low permissible levels of all metal content in radish tissues and increased radish productivity. Therefore, organic materials used herein can be applied for normal plant growth without metal contamination of the plant and the soil.

A field study was conducted to evaluate the effect of different plant growth regulators (PGRs) applied through seed priming and foliar spray on growth and yield of three okra cultivars grown under calcareous soils. The cultivars of Punjab Selection and Sabzpari produced significantly higher number of branches and leaves per plant, pod length and diameter and pod yield as compared to cv. Green ferry, while, cv. Punjab selection produced significantly greater number of flowers and pods per plant as compared to other two cultivars. Seed germination (%), plant height, and fruit set (%) were not affected by the cultivars. Among the PGR treatments, seed primed with GA3 resulted in significantly higher germination percentage and greater plant height at flowering. Seed priming and foliar spray with NAA and GA3 were effective in increasing the final plant height, number of branches, number of leaves, number of flowers and number of pods per plant and fruit set (%), fresh weight per pod and pod yield. However, pod diameter, pod moisture content and dry weight per pod were not influenced by the PGR treatments applied. These results suggested that the PGRs have great potential to improve seed germination, enhance growth and increase yield of okra cultivars under calcareous soils.

Authors: Bal Erdinç
Published: August 2019

The effect of alginate treatments with or without salicylic and oxalic acid as post-harvest coating in extending the postharvest life of plums (Prunus salicina L. cv. ‘Black amber’) and maintaining their quality were investigated. Plums were treated with 2% alginate coating with or without salicylic (1.0 mM) and oxalic acid (1.0 mM), and then stored at 0−1°C and 90 ±5% relative humidity for 40 days. The quality of plums was assessed at 10-day intervals by evaluating the following quality parameters: weight loss, soluble solids content, titratable acidity, firmness, respiration rate, ascorbic acid content, total anthocyanin content, total phenolic content and antioxidant activity. The respiration rate, weight loss and changes in quality parameters were much lower in coated plums as compared with the control. Alginate coating resulted in a significant reduction in weight loss of fruits. Alginate treatments with or without salicylic and oxalic acid were effective on delaying the evolution of parameters related to postharvest ripening, such as soluble solids content, softening and reducing respiration rate. At the end of the storage period, the edible coatings showed a positive effect on maintaining higher concentration of total phenolics, total anthocyanin content and antioxidant activity, which decreased in control plums as a result of over-ripening and senescence processes. The results suggested that the use of alginate enriched with salicylic acid could maintain considerably higher quality of fruits and level of bioactive compounds than other coating treatments during 40 days of storage at 0−1°C.

A protocol was developed for high frequency and low cost of in vitro shoot proliferation and ex vitro rooting of Eustoma grandiflorum (Gentianaceae) on solid medium. Shoot tips as explants were cultured on Murashige and Skoog (MS) medium enriched with different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D) (0.00, 0.01, 0.10 and 1.00 mg l–1) and 6-benzylaminopurine (BAP) (0.00, 0.50, 2.00 and 5.00 mg l–1). Three culture media systems (solid, liquid and double-phase) were applied. None of the explants cultured on liquid and double-phase media resulted in live plant production. Maximum axillary shoot number (54.45) was recorded in the plantlets treated with 0.10 mg l–1 2,4-D in combination with 5.00 mg l–1 BAP. Treatment of 0.01 mg l–1 2,4-D along with 0.50 mg l–1 BAP produced maximum node number and internode length. Some shoots produced on medium containing plant growth regulators (PGRs) were rooted in soil. The largest number (5.50/plantlet) and longest length of root (7.75 cm/plantlet) were obtained in ex vitro condition on the base of shoots produced in culture medium enriched with 0.10 mg l–1 2,4-D along with 0.50 mg l–1 BAP. The combination of 1.00 mg l–1 2,4-D and 0.50 mg l–1 BAP was found to be the most suitable PGRs for obtaining the highest callus weight. The most fresh weight was calculated from plantlets grown on the medium containing 0.10 mg l–1 2,4-D along with 5.00 mg l–1 BAP. Maximum dry weight was obtained in free-PGRs medium. About 90% of the rooted plantlets were established successfully in cultivation beds. Acclimatized plants were morphologically similar to the mother plants.

Celem pracy było oznaczenie zawartości związków polifenolowych, w tym także flawonoidów, w naparach z liści mniszka lekarskiego (Taraxacum officinale) w zależności od czasu i temperatury parzenia, a także wyznaczenie aktywności przeciwutleniającej badanych naparów. Próby suszonych liści mniszka lekarskiego o masie 2 g (±0,0001 g) zalewano wodą dejonizowaną (100 ml) o temperaturze początkowej 100°C, 80°C oraz 50°C. Oznaczenie zawartości polifenoli przeprowadzono przy użyciu odczynnika Folina-Ciocalteu. Zawartość flawonoidów w przeliczeniu na epikatechinę oznaczano spektrofotometrycznie. Aktywność antyoksydacyjną oznaczano z użyciem syntetycznego rodnika DPPH. Stwierdzono, że ogólna zawartość polifenoli w przeliczeniu na kwas galusowy wahała się od 14,18 mg/100 ml ±0,07 do 37,52 mg/100 ml ±0,04 w zależności od początkowej temperatury oraz czasu parzenia. Podobne uwarunkowanie wystąpiło w przypadku oznaczenia zawartości flawonoidów, która wynosiła od 9,61 mg/100 ml ±0,02 do 25,26 mg/100 ml ±0,2. Zdolność redukowania rodnika antyoksydacyjnego DPPH wahała się od 38,24% do 62,05%. Wyniki badań potwierdzają dużą zależność zawartości związków fenolowych w naparach z liści mniszka lekarskiego zarówno od czasu, jak i od temperatury parzenia.
