Machine Learning in a Molecular Modeling Course for Chemistry, Biochemistry, and Biophysics Students
Authors: Remington Jacob M. , Ferrell Jonathon B. , Zorman Marlo , Petrucci Adam , Schneebeli Severin T. , Li Jianing
Published: August 2020

Recent advances in computer hardware and software, particularly the availability of machine learning (ML) libraries, allow the introduction of data-based topics such as ML into the biophysical curriculum for undergraduate and graduate levels. However, there are many practical challenges of teaching ML to advanced level students in biophysics majors, who often do not have a rich computational background. Aiming to overcome such challenges, we present an educational study, including the design of course topics, pedagogic tools, and assessments of student learning, to develop the new methodology to incorporate the basis of ML in an existing biophysical elective course and engage students in exercises to solve problems in an interdisciplinary field. In general, we observed that students had ample curiosity to learn and apply ML algorithms to predict molecular properties. Notably, feedback from the students suggests that care must be taken to ensure student preparations for understanding the data-driven concepts and fundamental coding aspects required for using ML algorithms. This work establishes a framework for future teaching approaches that unite ML and any existing course in the biophysical curriculum, while also pinpointing the critical challenges that educators and students will likely face.
Design and formation of SiC (0001)/SiO2 interfaces via Si deposition followed by low-temperature oxidation and high-temperature nitridation
Authors: Kobayashi Takuma , Okuda Takafumi , Tachiki Keita , Ito Koji , Matsushita Yu-ichiro , Kimoto Tsunenobu
Published: August 2020

We report an effective approach to reduce defects at a SiC/SiO2 interface. Since oxidation of SiC may inevitably lead to defect creation, the idea is to form the interface without oxidizing SiC. Our method consists of four steps: (i) H2 etching of SiC, (ii) Si deposition, (iii) low-temperature (∼750 °C) oxidation of Si to form SiO2, and (iv) high-temperature (∼1600 °C) N2 annealing to introduce nitrogen atoms. The interface state density estimated by a high (1 MHz)–low method is in the order of 1010 cm−2 eV−1, two orders of magnitude lower than that of an interface formed by SiC oxidation.

Authors: Gamboa Graus Michel Enrique
Published: August 2020

La incidencia de la Estadística aplicada al desarrollo de investigaciones es ampliamente reconocida en la actualidad. Es cada vez más utilizada en la recopilación y análisis de datos referidos a conjuntos lo más numerosos posible, donde destacan la variabilidad y la incertidumbre. Sin embargo, en ocasiones se hace muy complicado el procesamiento de números tan elevados de datos. Como consecuencia, el objetivo fundamental de este artículo está dirigido a presentar el libro Excel EsComDE. La esencia de su empleo radica en sus potencialidades para la formulación de conclusiones válidas y toma de decisiones razonables. La escala para medir la Competencia de Dirección en Educación se empleó para la programación de este producto informático. Esta fue investigada, producida, publicada y socializada por el propio equipo de investigación. Los datos se recogieron a través de varios métodos, técnicas e instrumentos diferentes. Se muestra cómo se procede a la organización y clasificación de la información recopilada, de modo que se facilite la presentación en tablas y gráficos para reflexionar sobre el comportamiento de los datos. Esto es a partir de apreciarlo más rápidamente para poder comparar, valorar y generalizar en su análisis e interpretación. Se presentan, asimismo, ejemplos de investigaciones reales en las que se hizo uso de EsComDE. Con su implementación se obtiene información relevante relativa a cada dimensión, indicador y sub-indicador de tan importante competencia para el proceso pedagógico, para la formulación de conclusiones y toma de decisiones.

Análisis de los planteamientos de Miguel Escotet sobre desafíos en educación superior en una era de transición
Authors: Arteño Ramos Rómulo , León Ortiz Carmen del Rocío , Illicachi Gusñay Juan
Published: August 2020

La sociedad demanda continuamente de mejores condiciones de vida para la superación de los pueblos, el Estado y la Academia. Estos necesitan trabajar en armonía para poder suplir las necesidades que la sociedad exige, sean procedentes  del norte o del sur,  lo cual amerita salir de la zona de confort, aprovechar los conocimientos que evolucionan día a día, considerando aspectos estructurales del sistema educativo en la educación superior, las políticas gubernamentales, la relación estudiante - docente, la tecnología como herramienta de innovación constante, entender  que somos un mundo diverso y multicultural, que el estudiante busca salir de una esclavitud intelectual, para concebir que no se puede comparar a la Universidad como una empresa cualquiera al no dedicarnos al comercio de mercancías. La academia busca gestionar procesos de transferencia y transformación constante de nuevos conocimientos plasmados en logros de aprendizaje;  en esta etapa de transición  donde no se puede afirmar que existen verdades absolutas, miramos al futuro como impredecible;  en este mundo globalizado se busca formar alianzas estratégicas relacionadas con el mundo del trabajo, la cohesión social y el desarrollo profesional, formado dentro de un currículo flexible. Se utiliza una metodología de análisis crítico a los desafíos planteados por Miguel Escotet,  quien  afirma que “la universidad debe ante todo enseñar a pensar, crear la actitud hacia el riesgo de pensar, ejercitar el sentido común y dar rienda suelta a la imaginación creadora”. (Escotet, 2018, pág. 20).
La práctica de Mindfulness con profesores: beneficios en su autorrealización y crecimiento personal
Authors: López Hernáez Lara
Published: August 2020

El objetivo de este capítulo es evaluar el nivel de autorrealización y crecimiento personal de maestras en la Tribu Apache de San Carlos (Arizona). La muestra está formada por sesenta maestras de educación infantil, que recibieron formación en un programa de meditación Mindfulness (Atención plena) durante tres semanas. Se utiliza el "Cuestionario de autoconcepto y realización", AURE, (Aciego, Domínguez y Hernández, 2005; Domínguez, 2001), y los resultados muestran niveles favorables en su autorrealización y crecimiento personal. Seis meses después, el 84% de maestras que lo pusieron en práctica, respondieron los cuestionarios nuevamente y los resultados fueron aún mejores en casi todas las dimensiones del cuestionario. Por ello, al ver que es un programa eficaz, se apuesta por mejorar la calidad de programas Mindfulness en las escuelas, con una investigación de calidad: muestras amplias, participación de toda la comunidad educativa (familia), comparación de resultados longitudinales en diferentes países y culturas y creación de instrumentos más específicos.
En torno a la formación del filósofo (y del pedagogo): un enfoque radical
Authors: Herrán Gascón Agustín de la
Published: August 2020

El objetivo de este trabajo es observar al filósofo y a la Filosofía, y al pedagogo y a la Pedagogía, desde la formación o educación definida desde el paradigma radical e inclusivo. La metodología es dialéctica, destructiva y alternativa. Los resultados apuntan a que, desde el enfoque radical e inclusivo de la educación, la formación del filósofo y del profesor de Filosofía no están bien orientadas. Lo que se expone es transferible al pedagogo y profesor e investigador de cualquier materia. La respuesta no está en la Filosofía. Tampoco en la Pedagogía actual. Tal y como se propone, se requiere de un distanciamiento que facilite una toma de conciencia basada en una perspectiva suficiente, radicada en la formación plena, que no coincide del todo con lo que se denomina formación.

Interpretación simbólica de los trastornos del desarrollo en el ejercicio de la orientación escolar
Authors: Alegre del Rey María Ángeles
Published: August 2020

La  interpretación simbólica de los trastornos del desarrollo que se detectan en la escuela desvela estrategias de orientación escolar encaminadas a la evolución de la cultura escolar y social.

Es este un aspecto fundamental de cara a comprender en toda su complejidad, los trastornos del desarrollo (trastornos de espectro autista y trastorno de déficit de atención con hiperactividad) que en la etapa de Educación Infantil y Primaria principalmente se detectan en el ámbito psicopedagógico. La multidimensionalidad de factores a los que obedecen estos trastornos requiere no eludir la aplicación de esta perspectiva, que a su vez nos revelará el sentido que ha de adoptar la orientación escolar frente a los mismos. Pasaremos de una concepción meramente disfuncional de estas alteraciones del desarrollo a una concepción sintomática, indicativa de aquellos aspectos de la realidad sobre los que hemos de tomar conciencia.

Published: August 2020

The tanning industry is held to be an activity with the high budding for environmental pollution all over the world. Many Bacterial strains isolated from natural resources have been found to possess unique properties which make them useful for environmental cleans ups. So it is very important to find out an alternative ecofriendly way for the treatment of contaminated effluent. The objective of this study was to isolate, explore and pick out natural occurring bacteria capable of reducing heavy metals from tannery effluent collected from the Hazaribagh tannery industry of Dhaka. The pH value of all the effluents samples were ranged from 7.12 to 7.91.  Five bacterial strains were confirmed as Bacillus bataviensis, Bacillus aryabhattai, Micrococcus antarcticus, Bacillus proteolyticus and Bacillus paranthracis on the basis of their morphological, cultural, biochemical, and 16S rRNA gene sequencing. Among these five strains, Bacillus bataviensisD1 exhibited higher resistance to cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb) and arsenic (As) up to the amount of 550 µg/mL, 500 µg/mL, 500 µg/mL, 1050 µg/mL and 1100µg/mL respectively. Bacillus aryabhattai D2 and Micrococcus antarcticus D3 showed similar result to chromium (Cr) and Lead (Pb), but Bacillus proteolyticus B1 showed higher resistance to nickel (Ni) that is up to 250 µg/mL. From these results, it can be suggested that the identified heavy metal-adapted bacteria could be useful for the biosorption of heavy metal contaminated effluent.

Authors: MOHAMMED SANI SAMBO DATSUGWAI
Published: August 2020

Bacteriological quality and sensory evaluation of wine produced from blends of date palm fruit and cucumber juice using Saccharomyces cerevisiae was investigated. The yeast was isolated and identified using standard techniques. The S. cerevisiae inoculum was produced using standard procedures and used to ferment the blends of date and cucumber to produce wine. Five (5) samples of wine were produced  from date and cucumber at  various concentration of substrates, anaerobically (Aerobic fermentation were terminated after 6 days and the fermented ‘’musts’’ were sieved to remove the shaft and debris of the crushed fruits.During the anaerobic phase of fermentation, the filtrates obtained after sieving the ‘’musts’’ were transferred into anaerobic fermentation round bottom flask (s) and incubated at room temperature. An air trap were fixed to the fermenting jars. Fermentation were terminated after four (4) weeks). Physicochemical, microbiological  and sensory evaluation (using 7 point hedonic scale by 20 panelist) of the produced wine were studied. The yeast was identified as Saccharomyces cerevisiae. The physiochemical analysis of the produced wines showed that percentage of alcoholic content of wine B had the highest at 16.6 %, as Wine A had 15.8 %, Wine D had 13.17 %, Wine C had 11.17% and Wine E had 10.18% of alcohol content after fermentation. The suspected bacteria isolate were Corynebacterium sp. Neisseria sp, Corynebacterium sp., Micrococcus sp. Enterobacteriaceace sp. Lactobacillu sp.and  Micrococcus sp. and some fungi sp. were isolated from the wines before pasteurization for sensory evaluation. But no microorganisms were detected after pasteurization of the produced wines. The sample C (Date and Cucumber) of ratio 3:1  was significantly preferred (p<0.05) from other wine A, B, D and E in respect to the aroma, test and appearance and over all acceptability. The S. cerevisiae used in the production of the wines gave excellent results. Harnesing the date and cucumber for wine production will reduce post-harvest loss of the fruit (wastage), improve, conribute to the economy and reduce unemployment.

Artykuł jest próbą rekonstrukcji historii przyjaźni znanego filozofa Wincentego Lutosławskiego (1863–1954) i Juliusza Osterwy (1885–1947) poprzez zachowane ślady listowe i diarystyczne. Przyjmując porządek chronologiczny, autorka przedstawia okoliczności ich spotkania w Wilnie w 1925 oraz trajektorię podróży i zetknięć aż do śmierci Osterwy. Przy okazji wyłania się krąg ważnych miejsc, wydarzeń i postaci, które wywarły wpływ na obu korespondentów, m.in. Kraków i prapremiery sztuk Wyspiańskiego, Kosów Huculski i zakład przyrodoleczniczy Apolinarego Tarnawskiego. Wśród problemów poruszanych w tekście najważniejsze dotyczą charakteru wzajemnego wpływu Lutosławskiego i Osterwy: poprzez dzieła (słowo pisane, grę aktorską), bezpośredni, osobisty kontakt i formowanie poglądów, wspólne przedsięwzięcia (szczególnie istotne w okresie okupacji, gdy obaj mieszkali w Krakowie lub okolicach). W tekście pojawiają się też mało znane przykłady promowania teatru Reduta za granicą, którego podjął się Lutosławski. W aneksie do artykułu znalazła się edycja dwudziestu listów i kartek od Osterwy do Lutosławskiego z lat 1925–1943 przechowywanych w spuściźnie filozofa  w archiwum Nauki PAN i PAU w Krakowie.
Superação da dormência em macieira: efeito do frio combinado com uso de indutor de brotação
Authors: Anzanello Rafael , Christo Mariane Castanho , Sartori Gabriele Becker Delwing
Published: August 2020

A superação da dormência das gemas em macieira ocorre após um acúmulo de horas de frio (HF) no outono/inverno. Caso o ambiente não supra a necessidade de frio das plantas, insumos indutores de brotação para a superação da dormência são empregados. Avaliou-se a superação da dormência de gemas de macieira combinando o efeito do frio e o uso de indutor de brotação. Utilizou-se o indutor de brotação padrão para macieira (Dormex® 1% + Óleo Mineral 4% - D/OM) na ‘Royal Gala’ (RG) após a variedade receber diferentes tempos de frio. Estacas de ‘RG’ foram coletadas em abril/2016 e aplicado o D/OM, após 0, 100, 200, 300, 400, 500 e 600 HF. Um tratamento controle foi incluso, com frio constante de 7,2 ºC. No tratamento controle, a ‘RG’ superou a dormência com 549 HF, após análise de regressão (para alcance de 70% de brotação). Quando testado D/OM combinado com frio, os produtos não foram eficientes para superação da dormência após 0, 100 e 200 HF, atingindo aproximadamente 50% de brotação. Porém, quando o D/OM foi aplicado após 300, 400, 500 e 600 HF, as plantas responderam com alta taxa de brotação (acima de 90%). Neste caso, a superação da dormência (70% de brotação) com D/OM foi atingida após 255 HF. Conclui-se que o D/OM terá efeito somente se o ambiente suprir 46,4% ou mais da necessidade de frio do genótipo a campo.

Published: August 2020

The degradation of any ecosystem services (ES) and the benefits human being enjoy from nature freely involve multifaceted processes such as those in built environment. The ecological security and multiple functions of the coastal zone of Dar es Salaam is of paramount importance to the sustainability of its natural and anthropogenic systems. Therefore, permanent/temporary conversion of a piece of land for construction space provisions profoundly affects the functionality and connectedness of nature–anthropogenic ecosystem. This study quantified land use landcover changes from Landsat satellite imageries, then evaluated the changes using recognizable coefficients for ecosystem services values (ESV). Applying Geographical Information System (GIS) techniques, the impacts of built environment on ESV were analysed using land use landcover change (LULCC) transfer matrix, carbon stock dynamics and soil erosion influence on soil fauna. The results revealed expansive BE from 10.6 percent in 1995 to 22.8 percent in 2016. Loss of forest by 64.5 percent in the study period explained the declining total ESV by 56.1 percent and per capita recreation potential by 2.3 percent. Similarly, decreasing forest cover led to high carbon dioxide emission, notably, the 353.24 t CO2 ha-1 yr-1 in the period between 1995 and 2005. Furthermore, in 1995 bushland experienced high soil erosion while in 2016 built environment displayed a similar trend as the rest of the land use landcover (LULC) classes. From geospatial analysis, the southern area displayed significant vegetation cover change as compared to the built environment dominant in the northern section of Dar es Salaam coastline. Initiative to reducing built environment by 1 percent saves forest loss by 5.28 percent and carbon sequestration at a tune of 28.95 t CO2 ha-1 yr-1; hence improves ecological services values by 4.60 percent.

Published: August 2020

Lung cancer represents the world’s most common cause of cancer death. In recent years, we moved from a generic therapeutic strategy to a personalized approach, based on the molecular characterization of the tumor. In this view, liquid biopsy is becoming an important tool for assessing the progress or onset of lung disease. Liquid biopsy is a non-invasive procedure able to isolate circulating tumor cells, tumor educated platelets, exosomes and free circulating tumor DNA from body fluids. The characterization of these liquid biomarkers can help to choose the therapeutic strategy for each different case. In this review, the authors will analyze the main aspects of lung cancer and the applications currently in use focusing on the benefits associated with this approach for predicting the prognosis and monitoring the clinical conditions of lung cancer disease.

Published: August 2020

DNA have presented through experiments great variability in terms of its electronic characteristics. They have shown that it can acquire the behavior of a conductor, semiconductor or insulator, making it a good candidate for replicating at the mesoscopic scale electronic devices. In the present work, the quantum transmission coefficient is calculated for DNA chains of various lengths with the use of the decimation and renormalization procedure, within the tight binding approximation and the Lippmann-Schwinger scattering theory. Transmission-Energy profiles were obtained, which helped to infer electronic transport properties of the system, Additionally, the current-voltage relation for a 30-pairs chain was calculated as well, and compared with the experimental results of Porath et al. Results show the semiconductor characteristics of the molecule, and a resemblance with the work of Porath, showing the quality of the procedure and the model utilized.

The estimated prevalence of HCV in India is about 0.5-1.5% and is a leading cause of chronic liver disease and hepatocellular carcinoma rapidly transmitting as silent killer.This study was planned with an aim to determine awareness about Hepatitis C infection among medical students.A cross-sectional questionnaire-based survey containing 30 questions to assess the knowledge about Hepatitis C infection was conducted.Total 125 students participated, overall score of knowledge-based questions and about transmission of HCV infection were satisfactory. Majority of students were aware of HCV transmission and prevention but have not shown good results about laboratory diagnosis.Overall grasp of Hepatitis C by the studied group was good. However, there were serious gap in their knowledge of lab diagnosis which need to be filled. Knowledge about transmission was very good

Obstructive sleep apnea is the most common type of sleep disorder breathing.90%of them remain undiagnosed. These patients may be associated with an increased risk of perioperative complications. Our objective was to evaluate the proportion of surgical patients with risk of undiagnosed Obstructive sleep apnea. After research ethics board approval, patient attending preanesthetic clinic were asked to fill the STOP-Bang questionnaire. Prospective observational study is used with the sample size of 70 patients and the study duration is 4 months. In 70 patients, the proportion of surgical patients with the increased(intermediate-high) of developing Obstructive sleep apnea is 78%(55 patients) This study is conducted to find out the percentage of surgical patients having undiagnosed Obstructive sleep apnea can be identified and treated to prevent perioperative complications.
Are Browse-wrap Agreements Legally Binding: As Analysed Across Multiple Jurisdictions
Authors: Chandak Aashana
Published: August 2020

Browse-wrap agreements are e-contracts that lack the element of express consent which creates ambiguity in their enforcement across countries like India and Canada. The United States of America has through a plethora of case laws attempted to follow a framework with a adequate communication of notice system which is subjected to consumer protection concerns. With the recent enforcement of the General Data Protection Regulations(GDPR)in the European Union it has led to the complete abandonment of the browse-wrap agreements due to the lack of the consentbeing explicitly provided. Leading to the rise in the recognition of theclick-wrap agreements being adopted as a standardized form of e-commerce contracts across jurisdictions
Woody vegetation change over more than 30 years in the interior duneveld of the Kalahari Gemsbok National Park

Background and objectives: Long-term studies of woody plants in South Africa are scarce. This study, initiated in the late 1970s, therefore aids understanding of vegetation dynamics in the southern Kalahari by investigating woody vegetation
change at and away from a watering point.
Methods: At three sites, all woody individuals were counted by species in plots 0.5 or 1 ha in size. Seedlings were noted separately from the >0.2 m group of individuals.
Results: Vachellia erioloba and shrub density decreased over time whereas dwarf shrub species’ numbers fluctuated markedly. Additionally, no increase in density of known bush encroaching species (e.g. Grewia flava, Rhigozum trichotomum
and Senegalia mellifera) was found in this large conservation area.
Discussion and conclusion: The changes in density of the woody species seem to point to the importance of particular rainfall patterns or sequences of events over different years that are responsible for these changes in the southern Kalahari, and the evident lack of bush encroachment in this conservation area supports the notion that bush encroachment in arid savannas is driven primarily by land-use practices and not by elevated carbon dioxide levels that are sometimes provided as cause for encroachment.

The Mediterranean basin is known to be the cradle of many endemic species. Within mayflies (Insecta, Ephemeroptera), North African species belonging to the family Baetidae remain poorly known and, traditionally, affinities to European fauna were proposed. Recent studies, based on molecular reconstructions, showed closer relationships to Mediterranean islands fauna.

Baetidae were sampled from North-West Algerian wadis (Tafna basin) and involved in COI barcoding reconstructions. Seven species were identified. The subgenus Rhodobaetis is represented byBaetis atlanticusknown previously from Macaronesian islands, Europe and Morocco and the Maghrebian endemicBaetis sinespinosus. Specimens, previously identified as Cloeon cf. dipterum, correspond toCloeon peregrinatorand, until now, only reported from Macaronesia. Besides the confirmation of endemicity of some species, such asProcloen stagnicolaandB. sinespinosus, our molecular study showed quite original results for relationships between European, insular and Algerian species.Baetis maurusstood out as a North African endemic sister clade to an Iberian clade. Furthermore, we found clear interspecific distances between Algerian and European clades for A. cf. sinaica and B. cf. pavidus, suggesting the presence of cryptic species in Algeria. However, additional studies are needed, as, for the moment, no clear morphological characters were found to separate the different clades and support them as valid species.

Telomeric sequences are conserved across species. The most common sequence reported among insects is (TTAGG)n, but its universal occurrence is not a consensus because other canonical motifs have been reported. In the present study, we used fluorescence in situ hybridization (FISH) using telomeric probes with (TTAGG)6 repeats to describe the telomere composition of leafcutter ants. We performed the molecular cytogenetic characterization of six Acromyrmex Mayr, 1865 and one Atta Fabricius, 1804 species (Acromyrmex ambiguus (Emery, 1888), Ac. crassispinus (Forel, 1909), Ac. lundii (Guérin-Mèneville, 1838), Ac. nigrosetosus (Forel, 1908), Ac. rugosus (Smith, 1858), Ac. subterraneus subterraneus (Forel, 1893), and Atta sexdens (Linnaeus, 1758)) and described it using a karyomorphometric approach on their chromosomes. The diploid chromosome number 2n = 38 was found in all Acromyrmex species, and the karyotypic formulas were as follows: Ac. ambiguus 2K = 14M + 12SM + 8ST + 4A, Ac. crassispinus 2K = 12M + 20SM + 4ST + 2A, Ac. lundii 2K = 10M + 14SM + 10ST + 4A, Ac. nigrosetosus 2K = 12M + 14SM + 10ST + 2A, and Ac. subterraneus subterraneus 2K = 14M + 18SM + 4ST + 2A. The exact karyotypic formula was not established for Ac. rugosus. FISH analyses revealed the telomeric regions in all the chromosomes of the species studied in the present work were marked by the (TTAGG)6 sequence. These results reinforce the premise that Formicidae presents high homology between their genera for the presence of the canonical sequence (TTAGG)n.
Orientation and navigation in Bufo bufo: a quest for repeatability of arena experiments

Research on navigation in animals is hampered by conflicting results and failed replications. In order to assess the generality of previous results, maleBufo bufowere collected during their breeding migration and translocated to two testing sites, 2.4 and 2.9 km away, respectively, from their breeding pond in the north of Vienna (Austria). There each toad was tested twice for orientation responses in a circular arena, on the night of collection and four days later. On the first test day, the toads showed significant axial orientation along their individual former migration direction. On the second test day, no significant homeward orientation was detected. Both results accord with findings of previous experiments with toads from another population. We analysed the potential influence of environmental factors (temperature, cloud cover and lunar cycle) on toad orientations using a MANOVA approach. Although cloud cover and lunar cycle had small effects on the second test day, they could not explain the absence of homeward orientation. The absence of homing responses in these tests may be either caused by the absence of navigational capabilities of toads beyond their home ranges, or by inadequacies of the applied method. To resolve this question, tracking of freely moving toads should have greater potential than the use of arena experiments.

L’enfant est au centre de nos préoccupations, sa sécurité qui se doit de limiter les risques au maximum, son bien-être qui n’est en aucun cas négociable, son éveil qui doit être à la hauteur de ses capacités et des attentes de ses parents. Dans notre société moderne, tout (ou presque) est contrôlé, normé, programmé, et cette belle aventure qu’est la parentalité devient voyage organisé. Certes, nos jeunes parents empruntent des voies qui semblent pensées et tracées au mieux, mais au risque de laisser de côté des chemins sur lesquels ils auraient flâné au gré de leurs envies, alors bébé est accueilli dans un univers pensé pour lui, en fonction de lui. Il s’y épanouira, y prendra toute sa place, parfois aux dépens des limites qui devraient être les siennes. De tout ce monde-là il se nourrira, parfois au-delà de sa faim, et il sera boulimique de faire, de vivre, d’expérimenter… au point d’en perdre le sommeil.

This research aims to develop an interactive application to support people learning to play music instruments of orchestra music. Gamelan, a traditional music orchestra from Java, Indonesia was used as the object study. A model of gamelan orchestra learning application was proposed to support an easy way to learn how to play gamelan music instruments. Rule-based method was used to develop an interactive system to learn gamelan music instru-ments. The system was implemented into an application which supports us-ers in independently learning to play orchestra music instruments, especially in remembering notes sequences and playing the note according to the tem-po. An experiment involving two groups consisted of control and treatment groups were conducted to evaluate the proposed learning model. The results shows that the averages skill value of the members of the treatment group were higher than the members of the control group.
