Published: February 2018

Jumlah penduduk yang meningkat di Kabupaten Jember menyebabkan kebutuhan akan sarana transportasi di Jember semakin tinggi, khususnya pada transportasi umum jenis kereta api. Peningkatan yang terjadi terlihat dari jumlah penumpang di Daop 9 Jember. Pada tahun 2015 jumlah penumpang kereta api di Stasiun Jember yang semula berjumlah 640.000 penumpang meningkat menjadi 800.000 penumpang pada tahun 2016 (meningkat sekitar 20%). PT. KAI berencana untuk melakukan pengembangan stasiun Jember agar dapat memberikan kenyamanan dan pelayanan yang lebih baik bagi penumpang kereta api. Pengembangan Stasiun Jember ini akan mengakibatkan perubahan arus lalu lintas di sekitar stasiun, sehingga simulasi-simulasi lalu lintas akibat pengembangan stasiun perlu dilakukan. Simulasi lalu lintas dilakukan dengan membuat skenario arus lalu lintas di sekitar Stasiun Jember, hingga akhirnya dapat diketahui kinerja simpang pada daerah ini. Dalam penelitian ini, metode yang digunakan untuk pengambilan data volume lalu lintas dan inventarisasi yaitu dengan cara survei langsung di lapangan. Pada perhitungan kinerja simpang dan simulasi lalu lintas, metode yang digunakan yaitu metode MKJI (Manual Kapasitas Jalan Indonesia) 1997. Setelah dilakukan analisis, data kinerja simpang yang didapat pada jaringan jalan di sekitar Stasiun Jember sangat beragam. Pada simpang bersinyal, kinerja simpang paling tinggi terdapat pada Simpang SMPN 2 Jember dari kaki simpang timur atau pada Jalan Bedadung dengan tingkat pelayanan (LoS) F. Sedangkan pada simpang tak bersinyal, kinerja simpang tertinggi terdapat pada Simpang Hotel Nusantara dengan tingkat pelayanan (LoS) C. Kemudian, untuk mendapatkan kinerja simpang yang lebih baik di jaringan jalan Stasiun Jember setelah pengembangan, dilakukan manajemen lalu lintas yaitu : pengaturan arus lalu lintas, pemasangan rambu-rambu lalu lintas pada jaringan jalan, serta pengaturan ulang traffic light pada simpang bersinyal. Setelah dilakukan manajemen lalu lintas tersebut, didapat tingkat pelayanan yang lebih baik pada simpang bersinyal dan simpang tak bersinyal disekitar stasiun Jember, yang berarti skenario lalu lintas yang direkomendasikan layak untuk diterapkan di lapangan.

Crítica ao ideário neoliberal na educação: precarização e descaracterização da escola pública paulista
Authors: Derisso José Luis , Duarte Rita de Cássia
Published: February 2018

O presente artigo tem como objetivo abordar o processo de precarização e descaracterização da escola pública paulista no contexto da aplicação sistemática de políticas neoliberais – no quadro de um projeto de reformas do estado e da educação brasileira desencadeadas a partir de meados da década de 1990 – e problematizá-lo à luz da concepção de educação e de escola pública da Pedagogia Histórico-Crítica (PHC). Priorizou-se a rede oficial de ensino paulista, em nível de educação básica, por sua condição de maior sistema público de ensino do país bem como pela própria importância econômica e política do estado de São Paulo no cenário nacional. Neoliberalismo, reforma do Estado e da Educação, precarização do trabalho docente e descaracterização da educação escolar no que tange aos seus fins constituem ingredientes de uma mesma concepção de educação e de sociedade que a PHC tem todo o aporte teórico para criticar e se contrapor, justamente porque sua concepção de sociedade, de formação do indivíduo, de educação e de papel social atribuído à escola é diametralmente oposta e antagônica à do ideário neoliberal.

Published: February 2018

Recently, the issue of heavy metals are wastes is become popular such as Cu, Co, Pb, and etc. Furthermore, the presence of Cu together with paracetamol as pharmacy waste. Photocatalytic process could be an alternative to avoid the situation. This research investigated the influence of irradiation and the initial concentration of paracetamol toward TiO2-catalyzed photoreduction of Cu(II). The research aims to develop a photoreduction method that is catalyzed by TiO2 in the presence of paracetamol in reducing Cu(II) and paracetamol concentration. Cu(II) photoreduction process was (II) conducted in a close reactor equipped with a UV lamp. The remaining Cu(II) in solution was analyzed using Atomic Absorption Spectrophotometry (AAS) to determine its concentration and paracetamol concentration by visible spectrophotometry method. Results showed that the use of photocatalyst TiO2improves the photoreduction of  Cu(II), 15-45 minutes irradiation also contributes the increment, over the time a tiny decrease in photoreduction effectivity occur, however. At initial paracetamol concentration, 50 to 250 mg/L lead to an increase in photodegradation of paracetamol, and large decline occur over e.i. 250 mg/L,  however. The presence of paracetamol may increase the effectiveness of Cu(II) photoreduction due to the prevention of  radical OH• and electrons recombination. The most effective photoreduction of  25 mL solution of ion Cu(II) 10 mg/L is readily achieve in reaction conditions  using  20 mg of TiO2 by 45 minutes irradiation in the present of 25 mL of paracetamol 250 mg/L. By those Cu(II) ion was reduced by 98.87 % and 14.73 % of paracetamol was degraded.

The process of urbanization often results in the accumulation of risks within the urban fabric. These later develop into major vulnerabilities that can cause immense devastation in the event of a disaster. Therefore, as a city develops, it is essential to monitor its growth in order to 1) guide its development to avoid accumulating further risks and 2) enable the urban system to cope with the risks that already exist. This paper focuses on dealing with existing risks and the potential to address disaster-risk response within the existing firefighting framework. It identifies GIS-based spatial-analysis methods that can assist in determining the urban system’s capacity to accommodate the necessary service functions during both regular emergencies and disaster situations. As an example, response-capacity analysis for firefighting services in Yangon City is carried out to identify the inadequacies of the current system. These are then matched with the potential-fire-risk map to consider the demand increase for fire stations in disaster situations due to the likelihood of multiple ignitions. Areas where infrastructural and logistical improvements should be prioritized are discussed, and urban planning measures to help develop a safe and resilient city are considered within the developing-country context.

Authors: Sararit Titaya ,   Building Innovation and Management Center, Faculty of Architecture, Chiang Mai University 239 Huykeaw Road, Sutep Chiang Mai 50200, Thailand
Published: February 2018

This study focuses on some houses in Phang Nga Province in Thailand that were permanently relocated after the Indian Ocean tsunami in 2004. It aims to analyze extensions and improvements by residents who have lived in the houses for a long time. Most previous research has painted spatial extensions in a bad light because of the negative feedback from residents regarding post-disaster housing; this could mean that residents were less than satisfied with such houses in comparison to their previous ones with respect to construction, function, or size. Observing and interviewing residents allowed me to infer that spatial extensions can also represent the positive development of long-term recovery projects, as they increase the satisfaction of residents who, more than 10 years after the tsunami, have changed their lifestyles, family sizes, and jobs. It also demonstrates why residents are more satisfied with house types that allow them to carry out the required space adaptions or extensions when they have an increase in their income. In this study, it was observed that extensional space could also be a positive factor revealing the developments in residents’ lives as they showed their intent to live permanently in this type of housing even after the disaster.
A New IntelliSense Strategy Based on Artificial Immune System for Multi-Robot Cooperation
Authors: Xu Tao ,   School of Mechanical and Electrical Engineering, Henan Institute of Science and Technology Eastern HuaLan Avenue, Xinxiang, Henan 453003, China, Shi Zengyong , Li Xiaomin
Published: February 2018

In this paper, a novel intelliSense strategy based on an artificial immune system for multi-robot cooperation (MRC) is proposed. A laser range finder and camera are mounted on the robot to provide environmental information. Based on the principle of the artificial immune system, environmental information sensed by the robot is considered as an antigen while the robot is regarded as a B-cell and a possible node as an antibody. To improve exploration efficiency, the immune system is utilized in the single robot system (SRS) and multi-robotic system (MRS). Antibody-antigen affinity is calculated to choose optimal number of possible node, ensuring that the exploration path is optimal. Each robot explores independently according to affinity information, and cooperation among robots can be realized by utilizing the interactions among antibodies. In order to make the map merging strategy more persuasive, the Scale-Invariant Feature Transform (SIFT) feature is further used to identify the same region. In a real-context experiment, the proposed algorithm results in more accurate exploration, and it is verified that the proposed intelliSense strategy improves the accuracy and execution efficiency for mobile robots.
The evolved landscape of ePortfolios: Current values and purposes of academic teachers and curriculum designers
Authors: Rowley Jennifer , Munday Jennifer
Published: February 2018

As ePortfolios are increasingly being used in universities to help develop self-reflective practitioners, academic teachers and students need to develop the skills and processes required to implement them. During 2015, a series of webinars was presented by a cross-university team to provide professional development for academic teachers, curriculum designers and other staff interested in initiating or extending ePortfolio learning in their institutions. A survey was conducted with participants to gauge the depth of understanding and use of ePortfolios in degree programs. The survey aimed to clarify participants’ perception of the value of ePortfolio tools in Australian universities, and to identify future directions for developing knowledge and learning related to ePortfolios. Through the survey questions participants were able to provide information anonymously about their knowledge and use of ePortfolios. Respondents were also invited to be interviewed. Nine interviews, conducted in 2016, explored ePortfolio-users’ opinions of the learning tool. The results indicate that teachers’ use of the ePortfolio as a learning tool has evolved beyond that reported in the current literature. Furthermore, when used for reflection, assessment and documenting professional standards, the ePortfolio tool contributes to the students’ development of skills required to transition to future careers.
ESL in Australia – A chequered history
Authors: Oliver Rhonda , Rochecouste Judith , Nguyen Bich
Published: February 2018

A historical perspective of English as a second or additional language (ESL/EAL) in Australia reveals the field as in a constant state of flux, in spite of Australia’s status as a nation of immigrants. This paper provides a contemporary review of the various phases of English language teaching in Australia for both adults and school-aged learners. It does so in the context of earlier pro-British monolingual attitudes, external global forces, ongoing changes in education policy, more recent national assessment regimes and the various global and local developments in the teaching of second languages. Historically the impetus for teaching English as a Second Language came with large-scale post-World War II arrivals from Europe. Language support for child migrants was only introduced some time later and has continued, although decreasing in availability in recent years. From the 1970s, more focussed programs were instigated with the arrival of refugees from war-torn countries. In this paper we describe the constant changes experienced by the providers and the recipients of English language instruction in Australia. Theoretically, the development of ESL instruction in Australia began with an essentially post-colonial perspective whereby the process of assimilation focussed on normalising the difference and/or deficit of non-English speakers and attaining the language skills of normative white middle-class native speakers (Pavlenko, 2003). Despite various investments in multiculturalism, the non-native English speaker in Australia remains the ‘other’, subject to sometimes intermittent and ad hoc funded assistance.

Authors: Bildirici Ishak , Cetin Adnan , Menges Nurettin , Alan Yusuf
Published: February 2018

A series of tetrasubstituted pyrazole-3-carboxamides (3a?c) and pyrazole- 3-carbonyl thioureides (6a?c) were synthesized and their structures characterized by IR, NMR and elemental analysis. The antibacterial potential against specific Gram-positive and Gram-negative strains and the antifungal activities of all novel compounds were investigated. Structure?activity relationships (SAR) studies and some theoretical parameters (ClogP, CMR, PSA and ESP) of the compounds were performed on these two pyrazole derivatives. Pyrazole-3-carboxylate ester 2 was used for the synthesis of the carboxamide derivatives. The reactions of pyrazole-3-carbonyl isothiocyanate 5 with appropriate chiral amino alcohols were utilized for synthesizing the thioureide derivatives. Both of these types of pyrazole derivatives including a chiral moiety exhibited pronounced antibacterial activities. According to the present in vitro study, some of the promising compounds might be new candidates for a new generation of antibacterial drugs.

Published: February 2018

Two different ways of extracting antioxidative compounds (including soluble polyphenols) from rusks made from wheat flour with added millet (Panicum miliaceum L.) were compared, i.e., solvent extraction and in vitro digestion. Wheat flour was replaced by millet flour in amounts of 10, 20 or 30 wt. % (per dry mass). Solvent extraction was realized using a mixture of ethanol and water in different percentages, with or without the addition of formic acid. The total content of phenolic compounds (TPC) was determined using Folin? ?Ciocalteu reagent, while the antioxidative capacity was measured by the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay. The efficiency of solvent extraction was enhanced by the addition of formic acid. The addition of millet flour in amounts up to 20 % enhanced the antioxidative properties. It was shown that in vitro digestion was more efficient in the extraction of antioxidative compounds, in comparison with solvent extraction.

Introduction. The most common causes of subocclusive disorders are the adhesion, Crohn's disease and small bowel neoplasms. Plasmablastic lymphoma (PBL) is an aggressive distinct subtype of diffuse large B-cell non-Hodgkin lymphoma initially reported in the oral cavity of the HIV infected individuals. Case report. We presented a male patient with PBL of the small intestine as a rare cause of intestinal subocclusion, without HIV infection and negative serology for hepatitis C, hepatitis B, and Epstein-Barr infection. A 73-year-old male was admitted to our Center due to the one-year history of abdominal pain, weigh loss, non-bloody diarrhea, night sweating and pruritus. The patient underwent the ileocolonoscopic examination with the accompanying biopsy specimens. The results, based on the histopathological and immunohistochemical pattern, confirmed a diagnosis of PBL. Following the chemotherapy treatment, our patient underwent the resection of ileum. The postoperative histopathological report confirmed PBL as the final diagnosis. The patient was treated for the following 6 months with the chemotherapy according to the cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) protocol. Fatal outcome was due to acute myocardial infarct. Conclusion. PBL of the small intestine is a rare and unusual cause of subocclusive events. In our patient, an accurate histopathological verification of the detected changes in the ileum was of crucial importance for further treatment.

A questionnaire was employed to gather in socio-demographic profile, best practices employed, benefits and institutional factors. The study employed one shot sampling. The growth increments of mangroves in Punta Biao (0.0032 cm/day) was comparable with Bucana (0.0031 cm/day) but were significantly higher than the rest of the project sites.Sto. Rosario exhibited the lowest growth increment of 0.0007 cm/day. In terms of survival, Bucana and Punta Biao showed the highest survival rate of 96.87% and 99.62%respectively, while San Isidro obtained the lowest mean value of 13.71%. Two (2) types of area orientation found in the different project sites, midland and tidal/mud flats. Soil types were clay loam and sandy clay. High survival and high growth increment were observed in midland area with clay loam substrate while low survival observed in seaward areas with sandy clay substrate. The pH ranged from 6.46-7.23 while salinity ranged from 23ppt-35ppt.  Some of the contributing factors that influenced higher survival rate of PNAP Mangrove Rehabilitation Project in Davao del Sur include the used of matured mangrove propagates, staking prior to mangrove planting, regular monitoring at least every other day and carefully scraping epiphytes (e.g. barnacles and oysters) during mangrove’s early stage. This practices observed in all project sites regardless of percentage rate recorded.

Since 2003 the Pyla-Koutsopetria Archaeological Project has systematically investigated a small region near the modern village of Pyla in southeastern Cyprus. Within this study region, the Hellenistic site of Pyla-Vigla is set atop a promontory of the same name, a toponym meaning "lookout." Dating to the late 4th and early 3rd centuries B.C., the site was founded and occupied during a turbulent period in Cypriot history, one that saw the transition from rule by local city kingdoms to outright foreign imperial domination. Pyla-Vigla represents a key strategic position for warring Hellenistic kingdoms with interests in Egypt and those seeking to achieve superiority in the eastern Mediterranean. Recent archaeological work by the Pyla-Koutsopetria Archaeological Project has shed light on the lives of those living at a Hellenistic fort in Cyprus. Documenting sites like Vigla provides a valuable perspective on day-to-day life in the armies that shaped the Hellenistic world.

Leishmaniasis is a widespread parasitic disease that occurs as a result of infection with a unicellular parasite belonging to the genus Leishmania. Diagnosis by conventional methods is inaccurate and is not sensitive to confirm the genus infection. Here, we have investigated a methods for Leishmania genus diagnosis, which includes the technique of polymerase chain reaction to detect the presence of the parasite at in vitro for promastigote cultures using three genus-specific primer pairs to amplify HSP70, ITS, and ITS2. The results showed single band of ~1422, ~1020, and ~550 respectively. This study has proved the ability of these primer pairs to detect Leishmania infection and recommend them to be used for detection of leishmaniasis in hospitals and research centers.

La palabra es mi reino

Published: February 2018

¿Qué es lo que hago cuando enseño? Hablo. No tengo otra manera de ganarme el pan y tampoco tengo otra dignidad; no tengo otra manera de transformar el mundo y además no tengo otra manera de influenciar a los hombres. La palabra es mi trabajo; la palabra es mi reino. Mis alumnos tendrán, en su mayoría, una relación diferente con las cosas y los hombres; ellos construirán algo con sus manos; o bien hablarán y escribirán en oficinas, almacenes, administraciones; pero su palabra no será una palabra que enseñe; será un fragmento de acción, una orden, un plan, un esbozo de acción. Mi palabra no inicia ninguna acción, no ordena ninguna acción que pueda caer directa o indirectamente en la producción; hablo solamente para comunicarle a la generación adolescente lo que sabe y lo que busca la generación adulta.
Pulgarcita y Pulgarcito en el siglo XXI
Authors: Serres Michel
Published: February 2018

Este nuevo escolar, esta joven estudiante, nunca han visto un becerro, una vaca, un cerdo mucho menos un nido. En 1900, la mayoría de los humanos sobre el planeta, se ocupaban de la agricultura y la ganadería; en el 2010 Francia, como otros países semejantes al nuestro, sólo cuenta con un 1% de campesinos. Sin duda hay que ver allí una de las más inmensas rupturas de la historia desde el neolítico. En otro momento, referida a las prácticas geórgicas, la cultura cambia.Aquel o aquella que les presento ya no vive en compañía de los vivos, ya no vive en la misma tierra, no tiene pues la misma relación con el mundo. Él o ella solo ven la naturaleza arcadiana de las vacaciones, del tiempo libre o del turismo.Él habita la ciudad. Sus predecesores inmediatos, mucho más de la mitad, trabajaban el campo. No obstante, él se ha vuelto sensible a las cuestiones del medio. Prudente, él contaminará menos que los demás, adultos, inconscientes y narcisos.

Authors: Ruíz Solórzano Jaime
Published: February 2018

El siguiente texto constituye una entrada a la historia de la educación visual, acaecida en la ciudad de Neiva entre 1884 y principios del año 2004; es decir, desde la puesta en funcionamiento de la Escuela de Artes y Oficios hasta la expansión de lo que en su tiempo se llamó "la educación visual no formal". Para ello el escrito contempla los siguientes apartados 1. La educación visual a través del sistema educativo y los textos escolares, con dos apartados: uno sobre la educación artística y estética; otro inherente a los fotograbados, grabados e ilustraciones de los textos escolares. 2. La institucionalización de la educación visual que abarca, primero, la "Sección de Extensión Cultural del Departamento" y la creación del Instituto Técnico Universitario Surcolombiano ITUSCO; segundo, la "Escuela de Bellas Artes"; tercero, la Licenciatura de Artes Visuales de la Universidad Surcolombiana y "la educación visual no formal".
Evaluación de estrategias pedagógicas de implementación del Microdiseño Curricular de Física en la Facultad de Ingeniería Una experiencia educativa
Authors: Avendaño R. Álvaro , Casadiego Alix María
Published: February 2018

En la Universidad Surcolombiana existe un índice de deserción de 41 %, que si bien está por debajo de la media nacional, la propia universidad tiene su cuota de participación en este índice. El presente trabajo de investigación versa sobre el impacto de una propuesta metodológica, no autoritaria y carente de verticalidad, en la disminución de la deserción. La propuesta impulsa la amplia participación de los estudiantes en un proceso en el cual la calificación final depende de un continuo monitoreo de los avances de los estudiantes a lo largo del semestre.Para el logro de los objetivos se llevó a cabo un estudio cuantitativo y longitudinal lo largo de los períodos comprendidos entre el Semestre B del 2009 y el semestre B del 2011 con el fin de establecer la relación entre variables como participación y obtención de logros. La muestra abarcó a los estudiantes de la asignatura mecánica y electromagnetismo de la Facultad de Ingeniería (sede Neiva). La falta de éxito en los logros es uno de los factores de deserción.
Los grupos de discusión, una estrategia discursiva para el arte
Authors: Mora Anto Florencia , Martínez Ruiz Victor
Published: February 2018

Este artículo re-crea la manera como fueron configurados tres grupos de discusión que conversaron en torno a las prácticas artísticas contemporáneas, en el marco del proyecto de investigación Asomacandela, llevado a cabo por profesores integrantes del Grupo De Humanitate adscrito a la Facultad de Humanidades y Ciencias Sociales de la Universidad Javeriana Cali. La configuración de escenarios posibles al interior de entramados diversos, provocaría la múltiple mirada al asunto para que las nuevas prácticas no se asuman simplemente como objeto de conocimiento, sino como espacios para el pensamiento. Atendiendo la metodología propuesta por Jesús Ibáñez denominada Grupos de Discusión 2 se produjeron tres situaciones de discurso -durante el transcurso de la investigación-, entendidas como el conjunto de circunstancias en medio de las cuales se desarrolla un acto de enunciación oral3 por parte de una selección de actuantes, incluyendo a los investigadores. Durante tres sesiones, artistas y colectivos de artistas provenientes de diferentes espacios (gestión, creación, crítica) interactuaron a partir de preguntas generadoras respecto a la tensión política, epistémica, estética, académica, económica que desafían las llamadas prácticas artísticas contemporáneas.
Imagen y Educación: Algunas Implicaciones Didácticas

El arte moderno puede cifrarse en estos versos de Antonin Artaud: "Nada de espectáculo representación - una obra debe cambiar cada noche es necesario que la obra cambie". Esa tendencia al cambio es la que lo sitúa entre los fenómenos sociales de transformación, de construcción progresiva, que deben insertarse en el fenómeno social más trascendente de control o liberación de los individuos de una nación: La Educación.

Ciudad, ecología, clima y bien común: estado de situación, retos y perspectivas desde América Latina
Authors: Delgado Ramos Gian Carlo
Published: February 2018

El trabajo abre con una revisión de la problemática urbana en general y en América Latina, para luego dar cuenta de las principales implicaciones y retos inmediatos y a mediano plazo, así como las potenciales soluciones actualmente en discusión, sobre tododesde la perspectiva del metabolismo urbano y la ecología política urbana, o mejor dicho, de la ecología política del metabolismo urbano. Se analizan así los perfiles metabólicos de algunas ciudades latinoamericanas, incluyendo algunas cuestiones relacionadas alas implicaciones climáticas y socioambientales. Asimismo se revisa hasta dónde las principales soluciones propuestas en la literatura internacional y en la academia, contribuyen con la construcción de alternativas anti-sistémicas o, en su defecto, hasta dónderesultan ser apuestas de resistencia a cualquier cambio profundo de paradigma, que en el caso de lo urbano alude desde la perspectiva aquí asumida, a ciudades cuya función -espacial/territorial- se aleja de la acumulación de capital para en cambio construir,con acciones coordinadas y consensuadas de abajo hacia arriba y de arriba hacia abajo, asentamientos más justos, sustentables y resilientes, con relaciones más armónicas con los territorios aledaños y más allá.
