Pelaksanaan kurikulum 2013 dilakukan dengan pendekatan scientific, dengan proses pembelajaran yang diharapkan adalah yang kontekstual dan berpusat pada peserta didik (student centered active learning). Dalam pembelajaran dengan menggunakan kurikulum 2013, sangat dianjurkan agar guru mengutamakan penilaian kinerja (performance assessment). Akan tetapi pada praktiknya,  seorang guru akan mengalami kesulitan kaetika harus mengamati 30-40 peserta didik yang berada dalam satu kelas. Untuk mengatasi hal tersebut, guru bisa berkolaborasi dengan peserta didik dalam penilaian dengan menggunakan peer and self assessment. Dengan menerapkan peer and self assessment, keuntungan yang didapatkan peserta didik antara lain Pemahaman  standar kualitas kinerja , proses belajar lebih mandiri, pengembangan keterampilan metakognitif, pengembangan kemampuan berpikir kritis, belajar lebih banyak tentang hal-hal yang dipelajari ketika peserta didik melihat kinerja teman, praktik dan pengembangan keterampilan komunikasi dan social, penanaman karakter sekaligus pengetahuan.
PENINGKATAN TUNTAS BELAJAR FISIKA MELALUI PEMBELAJARAN FISIKA DENGAN MATERI AJAR BERWAWASAN SETS DAN PENDEKATAN SETS PADA POKOK BAHASAN FLUIDA STATIS DAN DINAMIS KELAS XI-IA SEMESTER 2 SMA NEGERI 2 SEMARANG
Authors: S Sumarno
Published: December 2019

Nilai Ulangan Blok Semester I tahun ajaran 2006-2007 siswa kelas XI IA-3 SMA Negeri 2 Semarang 55% tidak tuntas belajar Fisika. Hal ini disebabkan karena materi ajar dan pendekatan pembelajaran Fisika kurang menarik perhatian siswa. Untuk meningkatkan jumlah siswa yang mencapai tuntas belajar Fisika diberikan materi ajar Fisika berwawasan SETS dengan pendekatan SETS. Pada siklus I dengan konsep Fluida Statis. Pembagian kelompok merupakan bagian dari pendekatan SETS dibentuk berdasarkan pilihan siswa, dan terbentuk 6 kelompok beranggotakan 7 siswa untuk kelompok 1 sampai 4, sedangkan kelompok 5 dan 6 beranggotakan 8 siswa. Hasil yang dicapai pada siklus I : Aktivitas siswa dalam proses belajar mengajar meningkat, ditandai dengan peningkatan perilaku siswa, dan jumlah siswa yang mencapai tuntas belajar meningkat menjadi 75 %. Kelemahan pada siklus I, terletak pada jumlah anggota kelompok terlalu banyak, dan kemampuan akademik kelompok tidak merata.          Pada siklus II dengan konsep Fluida Dinamis, pembagian kelompok yang merupakan bagian dari pendekatan SETS diubah dengan menambah jumlah kelompok menjadi 8 kelompok, kelompok 1 sampai 4 beranggotakan 5 siswa sedangkan kelompok 5 sampai 8 beranggotakan 6 siswa. Pembagian anggota kelompok berdasarkan kemampuan akademik. Dengan mengubah jumlah kelompok dan anggota kelompok pada siklus II ternyata proses belajar mengajar menjadi lebij baik. Dalam menyelesaikan masalah anggota kelompok lebih aktif. Hasil yang dicapai pada siklus II : Aktivitas siswa mengalami peningkatan dari siklus I, jumlah siswa yang mencapai tuntas belajar menjadi 84 %.          Dari hasil yang telah dicapai pada siklus I dan siklus II, dapat disimpulkan bahwa materi ajar berwawasan SETS dengan pendekatan SETS dengan pembagian kelompok berdasarkan kemampuan akademik dapat meningkatkan aktivitas belajar siswa dan jumlah siswa yang mencapai tuntas belajar. Materi ajar Fisika berwawasan SETS dan pendekatan SETS dengan pembagian kelompok berdasarkan kemampuan akademik dapat menjadi salah satu model pembelajaran Fisika bagi guru.
On the nature of risk in the safety management of structurally complex systems
Authors: Bochkov A. V.
Published: December 2019

Aim.In the general case, a risk-oriented approach encompasses probabilistic methods of emergency processes and events simulation as well as deterministic methods. The use of probabilistic and deterministic estimations has been the focus of research aiming to improve safety and operational procedures. However, the experience of using probabilistic analysis only (essentially, one-criterium tool) has shown that this approach does not encompass all the required aspects of safety. The aim of the paper is to introduce (update) the definitions of the very concepts of “analysis” and “synthesis” as regards the risks for the purpose of research of safety of structurally complex systems (SCS) and design of systems for monitoring hazards and threats to their stable development thereof.

Method.The paper examines – from the point of view of systems science – the method of analysis and synthesis of risks as a development tool of advanced systems for monitoring SCS safety threats. The paper compares the primary current concepts of risk management in SCS and has shown that they should be developed and improved. A type of risk functionality is proposed that allows defining a safety solution by the value of mathematical expectation of losses, with appropriate corrections taken into account.

Result.The concept of “risks synthesis” is introduced as a scientific tool integrated with analysis that takes into consideration the existing connections between the elements of considered SCS in terms of a whole system in its entirety. Principles are formulated for the collection of comprehensive sets of data required for decision-making.

Conclusion.The proposed approach paves the way for the development of the method of risks synthesis and suggests the development of advanced expert systems to support decision-making regarding the safety of SCS as multifunctional and multilevel systems intended for both recording and analysis of each individual case (event), and prediction of trends and preparation of prevention measures as necessary.

Published: December 2019

Background:

Centilla asiatica L is a medicinal herb that has been widely used in folk medicine to
treat various diseases. Asiatic Acid (AA), a triterpene and a known component of this herb, has been shown to
display important biological activities, including anti-inflammatory, antibacterial, antidiabetic and antihyperlipidemic,
neuroprotective, anxiolytic and antidepressant, hepatoprotective, pancreas protective, and cardio-
protective.

Objective:

This review focuses on AA’s anti-cancer effects on the basis of published literature found in a number
of databases such as PubMed and Science Direct. Emphasis has been given to the mechanisms of action of
its anti-cancer effect.

Methods:

A literature survey was conducted using known databases such as PubMed and Science Direct using
the keywords ‘Asiatic acid’, pairing with ‘cancer’, ‘tumor’, ‘anti-cancer effect’, ‘cytotoxic effect’, ‘anti-tumor
activity’, ‘cell line’, ‘animal cancer’, and ‘human cancer’.

Results:

Findings suggest that AA exerts anti-cancer effects in several test systems through various pathways,
including oxidative/antioxidant, anti-inflammatory, cytotoxicity, apoptotic cell death, necrosis, anti-angiogenesis,
inhibition of proliferation and cell migration, and chemoprevention.

Conclusions:

AA may be an effective plant-based cancer chemotherapeutic agent and a promising lead for the
development of potent anticancer drugs.
Subtractive Proteome Mining Approach towards Unique Putative Drug Targets Identification for Salmonella typhimurium
Authors: Iftikhar Rabia , Rizwan Muhammad , Khan Sajid , Mehmood Azhar , Munir Anum
Published: December 2019

Background:

Salmonella typhimurium is a rod-shaped bacteria with a Gram-negative
genus, belonging to the Enterobacteriaceae family of microbes, which invades the intestinal lumen
of Human. Salmonella typhimurium is a root source, accounting for gastroenteritis in humans as
well as in other mammals. Gastroenteritisis associated with Salmonella Typhimurium interacts
with the contaminated food and water and spreads to nearby people in the area. Small intestine is
attacked by Salmonella, which then enter into the bloodstream momentarily, and are responsible
for millions of mortalities and morbidities around the globe. Salmonella typhimurium toxins cause
gastrointestiritis due to inflammation in the stomach and intestine in infants and young children. It
accounts for millions of deaths with a higher incidence rate in developing countries.

Methods: :

In the current research, subtractive proteome mining has been done to recognize putative
drug targets. The proteome was analyzed through blast in order to exclude homologous proteins.
Bacterial essential proteins were predicted and the participation of the essential genes in the
metabolic pathways has been analyzed.

Results: :

36 essential genes and 15 unique pathways have been identified as potential drug targets
among the total of 1934 proteins. The location of proteins is determined as an outer membrane. 3
proteins out of 36 essential proteins are recognized as putative drug targets.

Conclusion::

In the future, virtual screening for the evaluation of novel clinical compounds for the
identified proteins will be effective and valuable for Salmonella Typhimurium infection in Homo
sapiens.

Pharmaceutical Co-Crystals - Design, Development and Applications
Authors: Anand Rachna , Kumar Arun , Nanda Arun
Published: December 2019

Background:

Solubility and dissolution profile are the major factors which directly affect
the biological activity of a drug and these factors are governed by the physicochemical properties of the
drug. Crystal engineering is a newer and promising approach to improve physicochemical characteristics
of a drug without any change in its pharmacological action through a selection of a wide range of
easily available crystal formers.

Objective:

The goal of this review is to summarize the importance of crystal engineering in improving
the physicochemical properties of a drug, methods of design, development, and applications of cocrystals
along with future trends in research of pharmaceutical co-crystals. Co-crystallization can also
be carried out for the molecules which lack ionizable functional groups, unlike salts which require ionizable
groups.

Conclusion:

Co-crystals is an interesting and promising research area amongst pharmaceutical scientists
to fine-tune the physicochemical properties of drug materials. Co-crystallization can be a tool to
increase the lifecycle of an older drug molecule. Crystal engineering carries the potential of being an
advantageous technique than any other approach used in the pharmaceutical industry. Crystal engineering
offers a plethora of biopharmaceutical and physicochemical enhancements to a drug molecule
without the need of any pharmacological change in the drug.
Link Reliable On-Demand Multipath Distance Vector Routing for Reliable Video Streaming in MANET
Authors: Periyasamy Pitchaipillai
Published: December 2019

Background:

Due to the generic feature of AOMDV, it is widely used in Long-Term
Evolution (LTE) networks such as the Internet which requires new challenges to deploy conversational
real-time applications like VoIP (Voice over IP) and video conferencing.

Objective:

In AOMDV, the multiple routes between any source and destination pair are selected
based on minimal hop count which does not ensure reliable video content delivery as the communicating
nodes along the paths are prone to link failures and route breaks.

Methods:

To overcome such problems, the Link Reliable On-demand Multipath Distance Vector
(LROMDV) is proposed by modifying the Ad hoc On-demand Multipath Distance Vector
(AOMDV).

Results:

The LROMDV uses an enhanced Cumulative Expected Transmission Count (enh-CETX)
for selecting multiple routes between any source and destination pair to avoid link failures and
route breaks in Long-Term Evolution (LTE) networks.

Conclusion:

The performance of LROMDV on H.264/MPEG-4 AVC video streaming under
both Distributed Coordination Function (DCF) and Enhanced Distributed Coordination Function
(EDCF) using NS2.34 and Enhanced EvalVid framework is evaluated and the simulation result
shows the effectiveness of LROMDV.
Evolutionary Intelligent Data Warehousing Approach to Knowledge Discovery Systems: Dynamic Cubing
Authors: Kaur Harkiran , Singh Kawaljeet , Kaur Tejinder
Published: December 2019

Background:

Numerous E – Migrants databases assist the migrants to locate their peers
in various countries; hence contributing largely in communication of migrants, staying overseas.
Presently, these traditional E – Migrants databases face the issues of non – scalability, difficult
search mechanisms and burdensome information update routines. Furthermore, analysis of migrants’
profiles in these databases has remained unhandled till date and hence do not generate any
knowledge.

Objective:

To design and develop an efficient and multidimensional knowledge discovery framework
for E - Migrants databases.

Methods:

In the proposed technique, results of complex calculations related to most probable On-Line
Analytical Processing operations required by end users, are stored in the form of Decision Trees, at the
pre- processing stage of data analysis. While browsing the Cube, these pre-computed results are called;
thus offering Dynamic Cubing feature to end users at runtime. This data-tuning step reduces the query
processing time and increases efficiency of required data warehouse operations.

Results:

Experiments conducted with Data Warehouse of around 1000 migrants’ profiles confirm
the knowledge discovery power of this proposal. Using the proposed methodology, authors have
designed a framework efficient enough to incorporate the amendments made in the E – Migrants
Data Warehouse systems on regular intervals, which was totally missing in the traditional E – Migrants
databases.

Conclusion:

The proposed methodology facilitate migrants to generate dynamic knowledge and
visualize it in the form of dynamic cubes. Applying Business Intelligence mechanisms, blending it
with tuned OLAP operations, the authors have managed to transform traditional datasets into intelligent
migrants Data Warehouse.
A Survey of Load Balancing and Implementation of Clustering-Based Approach for Clouds
Authors: Sharma Anju , Pandey Rohit , Singh Simar P. , Kumar Rajesh
Published: December 2019

Background:

Generally, it is observed that there is not a single algorithm that classifies
the task using Quality of Service (QoS) parameters requested by the task but instead focuses on classifying
resources and balancing the task's using the availability of resources. In past literature, authors
divided the load balancing solutions in three main parts workload estimation, decision making, task
transferring. Workload estimation deals with identifying requirements for the incoming tasks on the
system. Decision making is done to analyze that whether or not load balancing should be performed for
the given node. If the decision for load balancing has been made then third step deals with transferring
task to appropriate node to reach a saturation point where the system will be in the stable state.

Objective:

To address this issue, our approach is more focused upon on workload estimation and its
main objective is to cluster the incoming heterogeneous task into generic groups. Another issue for
this approach is that the client demand varies for the number of tasks. Thus, some attributes may be
much more critical to a user then the others and this demand changes from user to user.

Methods:

This paper classify the tasks using QoS parameters and focused on work-load estimation.
The main objective is to cluster the incoming heterogeneous task into generic groups. For this, KMedoid
based clustering approach for cloud computing is devised and implemented. This approach
is then compared with its different iterations to analyses the workload execution more deeply.

Results:

The analysis of our approach is computed using cloudsim simulator. Results and computations
shows that the data is very uneven in initial times, as some clusters have only four elements
and others are having much more elements. Whereas after the 20th iteration data observed is more
normally balanced, so the clusters formed after 20th iteration were more stable than clusters formed
initially i.e. 1st iteration. The number of iterations is also minimized to do unnecessary clustering as
after a few steps the changes in medoids are very less.

Conclusion:

A brief survey of various load balancing techniques in cloud computing is discussed. These approaches are meta-heuristic in nature and have complex behavior and can be implemented in cloud computing. In our paper, K-Medoid based clustering approach for identifying the task into similar groups has also been implemented. Implementation is done on cloudsim simulation package provided by Cloud Labs, which is a java based open source package. The results obtained in our approach are limited to classification of tasks into various clusters. It would also useful where new task arrives and simply assign it to a VM that was created for some other element of that class. In future, this work can be expanded to create an effective clustering based model for load balancing.
Nasalização vocálica no português urbano de São Tomé e Príncipe
Authors: Araujo Gabriel Antunes de , Balduino Amanda Macedo
Published: December 2019

Este artigo examina comparativamente a nasalidade vocálica em duas variedades de português faladas em São Tomé e Príncipe: o português santomense (PST) e o português principense (PP). Pautados na análise da duração e dos formantes dos segmentos nasais (ṽN), nasalizados (ṽ.N) e orais (V), observamos dois processos de nasalização distintos nessas variedades: a nasalidade vocálica tautossilábica, engatilhada por uma coda nasal, e a nasalidade vocálica heterossilábica, promovida por um ataque nasal. Ambos os processos decorrem do espraiamento regressivo do traço [+nasal] para V, porém, enquanto a nasalidade tautossilábica é obrigatória, distingue significado e ocasiona o apagamento da consoante nasal em coda, resultando na duração alongada de ṽN em relação à V (48% para o PST e 60% para o PP), a nasalidade heterossilábica não é implementada em pretônicas, é opcional em tônicas e mantém a consoante nasal em ataque, refletindo, consequentemente, na duração de ṽ.N, a qual é equivalente à V.
Pontos Críticos do Dicionário Terminológico

Published: December 2019

Neste artigo, propõe-se uma reflexão crítica sobre determinados termos constantes no Dicionário terminológico que são, no dia a dia, ensinados aos discentes dos ensinos básico e secundário. Concretamente, questiona-se a classificação dos relativos cujo(a), cujos(as), onde e quanto(a), quantos(as) como determinantes, advérbio e quantificadores, respetivamente. O termo sujeito nulo, a subordinação adverbial, adjetiva e substantiva e ainda o termo adjetivo numeral são também, aqui, matéria de análise crítica.
Associação de eventos tonais em português de São Tomé
Authors: Braga Gabriela , Svartman Flaviane Romani Fernandes
Published: December 2019

O estudo prosódico das variedades de português tem mostrado comportamentos distintos referentes à associação de eventos tonais ao contorno entoacional, aproximando variedades ao mesmo tempo em que distancia outras. Neste artigo, descrevemos e analisamos a associação de eventos tonais ao contorno entoacional de enunciados declarativos neutros do português santomense (PST) à luz da Fonologia Entoacional integrada à Fonologia Prosódica. Comparamosos resultados obtidos da análise desta variedade africana de português com os descritos para variedades de português europeu, brasileiro e guineense, estudadas pela mesma perspectiva teórica. Embora em São Tomé e Príncipe a variedade lusitana (especialmente a falada em Lisboa) seja considerada como padrão, ao analisarmos o comportamento entoacional das sentenças declarativas neutras de PST, deparamo-nos com: alta densidade tonal, caracterizada pela associação de acentos tonais a todas as palavras prosódicas de um contorno entoacional; a palavra prosódica com o domínio relevante para associação de acentos tonais; contorno nuclear baixo (L* L%); e possibilidade de associação de acento frasal à fronteira direita de sintagmas fonológicos não finais de um sintagma entoacional. Tais características entoacionais são distintas daquelas atestadas para a variedade lisboeta, o que nos permite assumir o PST como uma variedade detentora de uma gramática entoacional própria, e não uma variedade defectiva do português europeu.
Representação fonológica e percepção de fala: O papel da pausa
Authors: Soncin Geovana , Tenani Luciani , Berti Larissa
Published: December 2019

Investigamos a percepção de pausas em fronteiras de frase entonacional (IP) no Português Brasileiro (PB) e abordamos a relação entre produção e percepção da fala. Vinte sujeitos adultos, falantes nativos do PB, sem distúrbios de linguagem e sem queixas auditivas, participaram de um teste experimental de identificação de pausa. Usamos estímulos auditivos nos quais a fronteira IP foi marcada por uma combinação de pausa e variação de altura ou apenas variação de altura. Os resultados são os seguintes: (i) quando os estímulos consistiam em uma combinação de pausa com variação de altura no limite IP, as pausas foram identificadas significativamente (ii) quando os estímulos não tinham variação de altura nos limites IP, as pausas não foram identificadas significativamente, (iii) quando somente ocorreu variação de altura, sem produção de silêncio, foram identificadas pausas na fronteira testada. Esses resultados corroboram o argumento de que a percepção de fala não depende inteiramente da recuperação de um padrão acústico e evidencia a importância da representação fonológica para a percepção e organização do estímulo auditivo percebido. Com base nos resultados, argumentamos que a percepção de pausa resultaria da ilusão perceptiva marcada pela combinação de diferentes tipos de informações linguísticas, em nível fonético-acústico e representacional.
Aprendizagem de categorias de palavras por análise distribucional resultados adicionais para Português Brasileiro
Authors: Faria Pablo
Published: December 2019

Uma criança adquirindo a língua deve descobrir quais são as categorias sintáticas em sua língua e atribuir palavras a uma ou mais delas. A questão que nos propomos a responder aqui é o quanto dessa aprendizagem pode ser realizada através da análise distribucional de enunciados. Para este fim, uma re-implementação do modelo computacional de Redington, Chater e Finch (1998) foi conduzida e aplicada a dados do Português Brasileiro, obtidos de corpora disponíveis publicamente, tanto com fala dirigida à criança, quanto com fala entre adultos. Os resultados de todos os experimentos são apresentados e discutidos. Estes experimentos investigam mais variáveis e aspectos envolvidos nesta tarefa de aprendizagem: tipos de contextos distribucionais, o número de palavras-alvo e de contexto assumidas, o valor da informação distribucional para as diferentes categorias, tamanho do corpus etc. Uma comparação entre a fala dirigida à criança e a fala entre adultos também é feita. Em geral, nossos resultados dão suporte aos de Redington et al. (1998), embora tenhamos encontrado algumas diferenças possivelmente importantes e até contraditórias. Também avaliamos a medida cosseno, comparando a performance obtida com ela à performance obtida com a correlação de Spearman usada no estudo de Redington et al. (1998). Esta última parece produzir melhor performance. Neste artigo, focamos numa análise quantitativa dos nossos resultados.
A influência da referencialidade, da definitude e da contração preposição+determinante no processamento de orações relativas
Authors: Bezerra Gitanna Brito
Published: December 2019

Neste artigo, apresentamos dois experimentos (questionários) que conduzimos para investigar a influência da referencialidade, da definitude e da contração preposição+determinante (contração P+D) no processamento de orações relativas. O primeiro experimento foi conduzido em português brasileiro e os resultados revelaram um efeito significativo da referencialidade e da definitude: a modificação do N2 (aposição local) foi mais observada quando o N2 era referencial e quando ele era introduzido por artigo indefinido. Os resultados não revelaram, porém, efeito da contração P+D. O segundo experimento foi conduzido em espanhol e focalizou a referencialidade e a contração P+D. Os resultados revelaram um efeito significativo dos dois fatores: a modificação do N2 foi mais observada quando o N2 era referencial e quando o artigo que o precedia não envolvia contração com a preposição. Com esses resultados, enfatizamos a influência dos três fatores investigados na interpretação de orações relativas, destacando a originalidade do efeito da contração P+D.
Conhecimento Implícito e Explícito da Flexão Nominal e Verbal em Português Língua Não Materna. Um Estudo sobre Aprendentes Chineses
Authors: Li Qunying , Flores Cristina Maria Moreira
Published: December 2019

A flexão verbal e nominal é um domínio resistente à plena aquisição no processo de aprendizagem de português língua segunda (PL2) por parte de alunos chineses. O presente trabalho dedica-se ao estudo do grau de conhecimento implícito e explícito da flexão nominal e verbal de PL2 em aprendentes chineses de L1 mandarim com elevado nível de proficiência. Depois de aplicado um inquérito para a recolha de dados sobre o historial linguístico dos 15 informantes, foram realizadas duas tarefas linguísticas, uma tarefa de imitação provocada e um teste de juízos de gramaticalidade com correção. Os resultados confirmam que: i) as causas fundamentais das falhas de flexão verbal e nominal são o baixo conhecimento implícito e o processamento desse conhecimento no ato de produção de fala; ii) os falantes têm elevado conhecimento explícito das estruturas analisadas; iii) no caso da flexão nominal, existe uma tendência marcada para substituir o plural pelo singular e para substituir o feminino pelo masculino; iv) no caso da flexão verbal, existe a tendência para substituir o pretérito perfeito ou imperfeito do indicativo pelo presente do indicativo, e a tendência de substituir a terceira pessoa do plural pela terceira pessoa do singular; v) existe um desequilíbrio em termos de nível de desenvolvimento do conhecimento implícito das diferentes categorias.

Published: December 2019

La predicción implícita es una herramienta valiosa para conocer el tipo de productos que se pueden obtener del bosque en un tiempo determinado y, de esta forma, planificar el manejo forestal sostenible. En la Sierra Norte de Oaxaca, México, existen rodales coetáneos de Pinus patula, una especie maderable de rápido crecimiento e importancia económica y ecológica. El objetivo de este estudio fue estimar el crecimiento y rendimiento maderable de esta especie a través de dos sistemas de predicción con el enfoque de modelos de distribución en clases diamétricas. La base de datos consistió en 132 distribuciones diamétricas, provenientes de 66 sitios permanentes de muestreo de 400 m2 localizados en Ixtlán de Juárez, Oaxaca, México. La distribución diamétrica del rodal se estimó mediante la función de densidad de probabilidades Weibull con los métodos de predicción de parámetros y predicción de percentiles. Asimismo, se ajustaron modelos de proyección del diámetro mínimo y diámetro medio cuadrático del rodal para recuperar los parámetros y estimar la estructura diamétrica de rodales a medida que cambia la edad. El mejor método fue el de predicción de parámetros, debido al sesgo menor en la predicción del volumen total con respecto a un sistema de proyección explícito diseñado para la especie. Por tanto, es preferente el uso de este sistema de predicción implícita para planificar el manejo de los rodales coetáneos de P. patula.

Tretinoin has an important role in wound healing process include improve fibroplasia and collagen synthesis, maintening humoral immunity, and neutralize steroid effect.Epithelization  and fibroblast proliferation were very important event in wound healing process. The aims of this study were studying epithelization and fibroblas proliferation on incision wound healing process using pre treatment of  Tretinoin 0,1%  topically on mice. This research used 24 male mice, 3 month of age, with 150 -180 gram of body weight. The mice were divided into 2 groups, control group (K) and treatment group (P). The control group was a group of mice with an incision wound, while the treatment group was a group of mice with an incision wound that received a pretreatment of Tretionin of 0.1% topically. Each group was divided into 2 sub groups K4, K7, P4, P7 based on time of samples collecting. K4 and P4 were examined at  day 4, while K7 and P7 were examined at day 7. Epithelialization was observed by measuring the length of the epithelial incision area, whereas fibroblast proliferation was performed by counting the number of fibroblasts in five field of view on histopathologic skin preparations processed by HE staining.In this study,pretreatment of Tretinoin 0,1%  topically can increase epithelialization and number of fibroblast significantly (p<0,05).This increase may be due to 1% Tretinoin in the tissues to induce keratinocyte basal proliferation including its migration to the skin surface via retinoic acid receptors ( RARδ)Pretreatment of Tretinoin 0,1% topically can increased epithelialization and number of fibroblast on incision wound healing process of albino rats

The treatments contained BSFL substitution with different composition, control group (P0) was given 100% commercial feed, (P1) was given a 5% BSFL substitution, (P2) was given a 10% BSFL substitution and (P3) was given a 20% BSFL substitution. Contribution margin (CM) analysis was used to determine the yields of the groups in this study. Results showed that the highest feed consumption rate is in P3, production (egg in total and weight), productivity and yields in P3 is the highest, although there's no difference between P0, P2 and P3 based on the analysis MANOVA.  BSFL substitution at 20% is recommended to the farmers to increase profits.
Importancia económica de las ciudades medias en México

El crecimiento urbano en México ha conducido a una participación económica más equitativa de las ciudades de acuerdo con el tamaño de su población. En particular, las ciudades de tamaño medio de población han ganado peso económico. El objetivo del presente trabajo es analizar la importancia de este tipo de aglomeraciones urbanas en la economía del país durante 2000 y 2010. Esto se prueba a través de la metodología planteada por la ley de Zipf, que mide la distribución del tamaño ―económico― de las ciudades por el coeficiente de Pareto. En términos econométricos, se emplean mínimos cuadrados ordinarios (MCO) con errores estándar robustos y se incluye toda la gama de ciudades considerando regresiones de rangos móviles. Los resultados permiten aceptar la hipótesis de un coeficiente de Pareto menor a la unidad en ambos años para submuestras de mayor tamaño, rechazando, por tanto, la ley de Zipf. En este sentido, se argumenta que las ciudades de tamaño medio de población tienen mayor peso económico relativo que el de cualquier otro tipo de aglomeración urbana.

República Dominicana es un país con un sistema eléctrico vulnerable, por ello las fallas son recurrentes y las pérdidas parciales y totales del sistema son una consecuencia latente en las últimas décadas, siendo el tiempo de restablecimiento el factor de mayor importancia en estos eventos. Por otro lado, la República Dominicana se encuentra en la trayectoria de los huracanes, por lo que la red eléctrica del país se ve amenazada en la temporada ciclónica. Ante esta situación, este país no cuenta con un esquema que permita restablecer el sistema en caso de que algún fenómeno o evento natural ocasione una falla en el suministro eléctrico. En el presente documento se plantea un método de remuneración y un esquema para el restablecimiento del sistema de forma rápida y eficaz; esto se logra conociendo los puntos vulnerables del sistema, las generadoras con la capacidad de realizar el servicio de black-start y con la ayuda de herramientas de simulación para estimar el tiempo de respuesta del sistema. Para la realización de este programa se plantea la situación actual del sistema y se compara con países similares que tengan un sistema de restablecimiento óptimo, analizando las maniobras y variables tomadas en cuenta para su realización. Adicionalmente, se plantea el impacto de este algoritmo en los ámbitos económico, social, legal, técnico y ambiental evidenciando el antes y después del sistema eléctrico dominicano con la implementación de la propuesta, además de observarse los ahorros financieros que tendría el Sistema Eléctrico Nacional Interconectado (SENI) al implementar dicha metodología.
Invisible brokers: “citizen science” on Twitter
Authors: Tancoigne Elise
Published: December 2019

Who speaks for “citizen science” on Twitter? Which territory of citizen science have they made visible so far? This paper offers the first description of the community of users who dedicate their online social media identity to citizen science. It shows that Twitter users who identify with the term “citizen science” are mostly U.S. science professionals in environmental sciences, and rarely projects' participants. In contrast to the original concept of “citizen science”, defined as a direct relationship between scientists and lay participants, this paper makes visible a third category of individual actors, mostly women, who connect these lay participants and scientists: the “citizen science broker”.
CONTAÇÃO DE HISTÓRIAS, EM/COM LIBRAS, NO YOUTUBE
Authors: Corrêa Adriana Moreira de Souza , Brito do Nascimento Antonio Joamir
Published: December 2019

As histórias divulgadas nos meios digitais contribuem para a inserção de outras línguas e linguagens como semioses que permeiam as novas práticas de leitura. Neste trabalho, trataremos de canais do Youtube que disponibilizam essas histórias, gratuitamente, utilizando-se da Língua Brasileira de Sinais - Libras e/ou do Português como línguas que expressam as narrativas. Para tanto, descreveremos dez canais que se enquadram nessas características, os quais classificamos em três grupos: somente em Libras, com Libras em primeiro plano, com Libras em segundo plano, de modo a identificar as contribuições dessas histórias para as práticas escolares e não escolares. Trata-se de uma pesquisa exploratória, pautada na revisão bibliográfica e na análise de canais que se mostraram produtivos por conterem 141 histórias, em vários gêneros, que podem promover a aquisição da língua, acesso ao repertório cultural de determinado grupo e ampliar o conhecimento de si e do mundo nas pessoas surdas, além de divulgar a Libras, estimular o aprendizado pelo surdo e a inclusão.
Efisiensi Protein Ayam Broiler yang Diberi Ampas Tahu Fermentasi dengan Saccharomyces cerevisiae (Protein Efficiency of Broiler Chicken Fed fermented Waste Tofu with Saccharomyces cerevisiae)
Authors: NURHAYATI Nurhayati , Berliana Berliana , Nelwida Nelwida
Published: December 2019

Tujuan dari penelitian ini adalah untuk mengevaluasi pertambahan bobot badan dan efisiensi penggunaan protein pada ayam broiler yang diberi pakan mengandung  ampas tahu hasil fermentasi menggunakan Saccaromyces cerevisae. Ampas tahu difermentasi menggunakan Saccharomyces cerevisiae sebanyak 2 % dengan lama waktu fermentasi 72 jam. Setelah dipanen dianalisa kandungan nutrisinya dan diberikan pada ayam broiler sebanyak 200 ekor selama 5 minggu pemeliharaan. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dengan 4 ulangan. Perlakuannya yaitu P0= Pakan komersil (kontrol), P1 = Pakan komersil + 10 % ampas tahu fermentasi, P2 = Pakan komersil + 20%    ampas tahu fermentasi, P3 = Pakan komersil + 30% ampas tahu dan P4 = Pakan komersil + 40% ampas tahu fermentasi. Peubah yang diamati adalah konsumsi ransum, konsumsi protein, dan efisiensi penggunaan protein. Data yang diperoleh di analisis ragam dan pengaruh perlakuan terhadap peubah yang diamati diuji dengan uji Jarak Berganda Duncan. Hasil analisis ragam menunjukkan bahwa penggunaan ampas tahu hasil fermentasi dengan Saccharomyces cerevisiae sampai level 20% tidak berbeda  nyata (P>0.05) dengan kontrol, tetapi semakin tinggi penggunaannya (>20%) dalam pakan nyata (P<0.05) menurunkan konsumsi pakan, konsumsi proein. Dari hasil tersebut dapat disimpulkan bahwa penggunaan ampas tahu fermentasi dalam pakan broiler dapat digunakan sampai 20% untuk memperbaiki efisiensi penggunaan protein.
Nivel de satisfacción en los funcionarios de centros universitarios de una universidad estatal de Costa Rica
Authors: Arce Espinoza Lourdes , Rojas Sáurez Karla
Published: December 2019

Introducción: la satisfacción personal se ha estudiado desde 1930 y han surgido varias teorías, sin embargo, todas concluyen que la satisfacción es subjetiva y depende de factores extrínsecos e intrínsecos de cada individuo. Objetivo: medir la satisfacción respecto a la vida, el trabajo y el país en el personal de una universidad costarricense. Métodos: se aplicó un cuestionario en línea de octubre de 2017 a octubre de 2018. La satisfacción se midió en tres dimensiones: aspectos de la vida, el trabajo y el alcance nacional. Resultados: respondieron 363 miembros del personal de 39 centros universitarios. Su índice de satisfacción personal es generalmente alto, particularmente para los encuestados en entornos rurales, los mayores de 40 años y aquellos que han estado más tiempo en sus puestos de trabajo. Conclusiones: la edad, el tiempo en el trabajo y los entornos rurales se corresponden con la palanca de la satisfacción personal.
RETRATOS SOCIOLÓGICOS DO MARACATU DE BAQUE SOLTO: Percursos, disposições, práticas e variações culturais
Authors: Sena José Roberto Feitosa de
Published: December 2019

O presente texto, resultado de uma pesquisa doutoral, pretende colaborar para reflexão sociológica sobre a necessidade de abordagens em escala individual aplicadas aos estudos de cultura popular investigando os atores do Maracatu de Baque Solto, manifestação oriunda das classes populares em Pernambuco. Tentando pensar a cultura popular sob a perspectiva disposicionalista e contextualista, a pesquisa traz à baila o caso dos indivíduos visando observá-los/analisá-los em diferentes contextos da ação, refazendo suas trajetórias sociais a fim de analisar, em nível diacrônico-sincrônico, suas ações plurais e variações culturais. Tal objetivo foi possível com a aplicação dos retratos sociológicos de indivíduos, a partir da reconstrução de suas trajetórias de vida nos mais variados e contínuos processos plurais de socialização. Essa abordagem se embasa, principalmente, na perspectiva teórico-metodológica de Bernard Lahire e nos casos de aplicação/atualização desta na sociologia lusófona, especialmente portuguesa. A investigação aprofundada em escala individual não negligencia os demais níveis e é pertinente para a percepção das micromobilidades, hibridismos, circularidades culturais e variações inter e intraindividuais. O artigo apresenta uma discussão teórico-metodológica sistemática e, ao final, um dos retratos sociológicos resultantes da pesquisa.

AS INDIVIDUALIDADES POPULARES: análise de setores urbanos no Chile
Authors: Araujo Kathya , Martuccelli Danilo
Published: December 2019

As ciências sociais em geral propuseram leituras das classes populares e do popular que tenderam a minimizar a existência de formas de individualidade em seu seio, dando lugar a visões altamente coletivistas de seus membros. Com base em duas investigações empíricas de tipo qualitativo sobre o caso do Chile, realizadas mediante entrevistas semiestruturadas e técnicas grupais, este artigo discute que, sem desconhecer a comunidade de experiências observável entre seus membros, é possível dar conta de certos processos individualizadores específicos nesse grupo social. Frente às numerosas adversidades de sua existência em um contexto de alta instabilidade posicional e de exigência de hiperatuação, os membros dos setores populares urbanos tendem a afirmar a sua individualidade a partir de três dimensões: a força do caráter; a habilidade e o sentido de oportunidade; e o prazer e a irreverência humorística.

Resistance, resilience, and resurgence: tracing the rs in indigenous literary studies
Authors: Beard Laura Jean
Published: December 2019

This text explores theoretical terms—resistance, resurgence, resilience, respect, reciprocity—in contemporary Indigenous literary studies in North America while pointing out that the many of the powerful stories by Indigenous authors that center on the importance of respect, reciprocal relationships, responsibility, and reverence might serve as maps for us all through some of the thorny issues in today’s world.
