Storyteling In Teaching Vocabulary ( an EFL Seting In Indonesia Primary School Context)
Authors: Ananthia Winti
Published: August 2016

Abstrak

Bahasa Inggris telah menjadi salah satu bahasa yang memegang peranan penting pada pergaulan tingkat global, baik didalam konteks personal maupun profesional. Di Indonesia, hal ini berpengaruh terhadap kebijakan diberlakukannya pembelajaran bahasa Inggris di tingkat sekolah dasar sejak tahun 1994. Akan tetapi, kebijakan memasukkan pelajaran bahasa Inggris pada kurikulum SD bukan tanpa masalah. Masalah yang sering dihadapi pada konteks tersebut diantaranya adalah ketersediaan guru bahasa Inggris SD yang berkualitas, yang dapat menjalankan pembelajaran bahasa Inggris sesuai dengan karakteristik siswa SD. Penggunaan metode bercerita (storytelling) dalam pembelajaran bahasa Inggris sebagai bahasa asing telah direkomendasikan sebagai salah satu metode untuk membelajarkan vocabulary oleh para ahli di bidang English as a Second/Foreign Language (ESL/EFL). Brewster, Ellis dan Girard (2002) menyatakan bahwa penggunaan storytelling dapat memotivasi siswa SD untuk belajar bahasa asing, khususnya bahasa Inggris. Artikel ini membahas tentang penggunaan storytelling dalam membelajarkan vocabulary bagi siswa sekolah dasar, khususnya di kelas rendah dikaitkan dengan the four strands approach yang dicetuskan oleh Nation (2001). Selain itu artikel ini memuat pula contoh singkat kegiatan pembelajaran bahasa Inggris yang membelajarkan vocabulary pada siswa SD kelas 1 dengan mengadopsi cerita The Very Hungry Caterpillar karya Eric Carle.

Kemampuan Pemecahan Masalah Matematis Siswa Sekolah Dasar
Authors: Mulyati Tita
Published: August 2016

Abstrak

Pemecahan masalah merupakan salah satu kemampuan yang harus dikuasai siswa setelah belajar matematika. Kenyataannya, di SD, pembelajaran matematika yang mengembangkan kemampuan pemecahan masalah belum mendapat banyak perhatian dari guru-guru. Kurangnya perhatian guru terhadap pengembangan kemampuan pemecahan masalah dalam proses pembelajaran matematika mengakibatkan siswa kurang memiliki kemampuan pemecahan masalah. Kekurangan masalah non-rutin dalam buku sumber (teks) menjadi salah satu penyebabnya, selain itu guru terbiasa mengadopsi soal-soal yang terdapat pada buku sumber.Selain itu, pendekatan abstrak dengan metode ceramah dan pemberian tugas sangatlah dominan dari setiap kegiatan pembelajaran matematika di SD. Diperlukan pembelajaran yang mengintegrasikan pengetahuan, keterampilan, dan pemikiran yang kreatif serta lebih menekankan pada pengalaman dan keterlibatan siswa secara aktif dalam pemecahan masalah. Salah satu pembelajaran yang bisa dilakukan yaitu dengan menerapkan pendekatan pendidikan matematika realistik.

ABSTRAK 

Upaya untuk meningkatkan kinerja pendidikan dalam mencetak sumber daya manusia yang unggul dan berkarakter saat ini sedang gencar-gencarnya dilakukan. Salah satu upaya ini adalah dengan mengembangkan satu program pendidikan yang dikenal dengan istilah pendidikan budaya dan karakter bangsa.Pendidikan karakter bertujuan agar siswa mampu menjadi orang yang berkarakter mulia. Usaha pengembangan karakter ini harus dilakukan secara bekesinambungan dalam proses pembelajaran. Secara praktisnya, pembentukan dan pengembangna karakter ini bersifat integratif dengan aktivitas belajar yang dilakukan siswa. Oleh sebab itu, untuk mampu mengukur perkembangan karakter siswa diperlukan sebuah alat yang secara otomatis mampu mengukur aktivitas dan sekaligus menunjukkan karakter siswa. Alat itu adalah penilaian otentik.Penilaian otentik merupakan sebuah bentuk penilaian yang mengukur kinerja nyata yang dimiliki siswa. Kinerja yang dimaksud adalah aktivitas dan hasil aktivitas yang diperoleh siswa selama proses pembelajaran. Berdasarkan pemahaman ini penilaian otentik pada prinsipnya mengukur aktivitas yang dilakukan oleh siswa selama proses pembelajaran berlangsung.

O objetivo deste estudo foi identificar qual o nível de adequação dos comitês de auditoria das empresas dos níveis diferenciados da BM&FBOVESPA às regras da SOX, Bacen, Susep e IBGC. A adequação foi analisada por meio de um check-list, construído com base nas principais normas e recomendações às quais as empresas brasileiras estão sujeitas. A análise pautou-se nas seguintes características: composição, qualificação, mandato, quantidade de reuniões, atribuições e obrigações. A pesquisa se caracterizou como descritiva, predominantemente quantitativa e documental. Compreendeu 58 empresas e abrangeu 1.508 verificações que possibilitavam identificar o nível de adequação médio de 50% (13 de 26 questões), com a máxima de 88% (23 questões) e a mínima de 4% (1 questão). Os resultados apontaram que as instituições financeiras e as instituições de previdência e de seguros formam o grupo que está mais adequado às regras no que tange ao comitê de auditoria, enquanto as empresas submetidas à SOX e as demais apresentaram os índices mais baixos da amostra. Além disso, não se encontrou relação entre os níveis diferenciados de governança corporativa e o índice de adequação dos comitês, ou seja, possuir classificação no novo mercado não garante uma boa adequação às normas referentes ao comitê de auditoria.

Authors: Silva Taís Duarte , Miranda Gilberto José
Published: August 2016

As questões a respeito da adoção das normas internacionais na contabilidade têm sido assunto frequentemente discutido, buscando-se entender os possíveis impactos percebidos nas empresas após a promulgação da Lei 11.638/2007. Nesse contexto, embora a adequada gestão do capital de giro seja crucial para vida das organizações, poucos estudos têm sido realizados. Assim, o presente trabalho teve como objetivo comparar os indicadores da administração do capital de giro, antes e após a adoção da referida Lei, sendo esses: capital circulante líquido, necessidade de capital de giro, saldo em tesouraria e índice de liquidez. Para tanto, foi realizado um estudo descritivo, utilizando-se a análise documental, a partir de demonstrações contábeis, e com abordagem quantitativa. A amostra do estudo foi composta por 35 setores da economia, calculando-se, assim, os indicadores de todas as empresas desses setores, referente ao período que compreende os anos de 2004 a 2013, o que permitiu a comparação de um período de quatro anos antes e quatro anos após a adoção das normas internacionais. A fim de identificar variações significativas nos indicadores, foi utilizado o teste não paramétrico Mann-Whitney. Os resultados apontaram mudanças significativas nos indicadores CCL, ST e ILNCG, não havendo mudança significativa no indicador NCG, o que sugere que os ativos e passivos financeiros sofreram mais alterações do que os ativos e passivos operacionais.

Authors: Tokarek Wiktor , Listwan Stanisław , Pagacz Joanna , Leśniak Piotr , Latowski Dariusz
Published: August 2016

Fucoxanthin, diadinoxanthin and diatoxanthin are carotenoids found in brown algae and most other heterokonts. These pigments are involved in photosynthetic and photoprotective reactions, and they have many potential health benefits. They can be extracted from diatom Phaeodactylum tricornutum by sonication, extraction with chloroform:methanol and preparative thin layer chromatography. We assessed the utility of an additional column chromatography step in purification of these pigments. This novel addition to the isolation protocol increased the purity of fucoxanthin and allowed the concentration of diadinoxanthin and diatoxanthin before HPLC separation. The enhanced protocol is useful for obtaining high purity pigments for biochemical studies.

Authors: Putranto Terawan Agus , Yusuf Irawan , Murtala Bachtiar , Wijaya Andi
Published: August 2016

BACKGROUND: Recently, stroke therapy is focused on reperfusion therapies for restoring cerebral blood flow (CBF) and minimizing the undesired effects of neuron ischemia. However, the thrombolytic therapy to restore CBF was restricted with narrow time window. On other hands, not many patients can reach the treatment immediately after the onset of stroke. A wider time window therapy that might increase CBF would probably helpful. This study aims to investigate the CBF improvement after intra arterial heparin flushing (IAHF) therapy in chronic stroke patients.METHODS: A clinical trial was conducted with time sampling. We collected chronic ischemic stroke subjects (with stroke onset ≥30 days) within periods February-September 2015. We investigated CBF before and after IAHF treatment in 75 chronic stroke patients. The difference before and after IAHF treatment in subgroup which is classified with infarct size and lesion area was tested. CBF was measured using MRI Quality Arterial Spin Labeling (qASL) with region of interest around infarct lesion.RESULTS: We found a significant CBF improvement (p<0.001) around infarct area after IAHF treatment with average 10.39mL/100g/min raised. CBF improvement was found in lacunar infarct (p<0.001) and non lacunar (p<0.001), also in infarct in cortical (p<0.05), subcortical (p<0.001) and both area (p<0.05).CONCLUSION: IAHF is associated with increased CBF around infarct area and IAHF probably offers some benefit for chronic stroke.KEYWORDS: IAHF, CBF, chronic stroke, ischemic, lacunar, non lacunar, cortical lesion, subcortical lesion

CFD Simulation and Microscopic Study of a Solitary Spherical Porous Adsorbent
Authors: White John
Published: August 2016

Modelling water vapour flow, heat transfer and porosity in porous adsorbent is somewhat challenging simulation problem. Primary macroscopic water vapour flow models, such as Darcy's law, fail to predict the pressure drop entirely correctly for the reason that many of flow parameters not considered because of the simplifications that remain made for the multi-scale structure of the porous adsorbents. For one to develop a good physical understanding of such water vapour flows and the accuracy of existing 3D simulation models, there is a need for some accurate 3D geometry to be studied. This present work describes two-phase water vapour flow and adsorption/ desorption performed on porous adsorbent by a Dynamic vapour sorption (DVS). The CFD simulation results are associated with experiments results. It is decided that for such complex porous adsorbent CFD simulation problems the use of COMSOL Multiphysics and SolidWorks flow simulation will be utilised.

Published: August 2016

The organizational climate has played a crucial role in an organization/institution resulting in high individual, organizational performance and specially motivation to work. Motivation is the process of stimulating people to action and to achieve a desired task and healthy organizational climate in an individual’s expressed career related goals or choices. The organizational climate is very much related with motivational aspects. Teacher educators play an important role in bringing about social transformation leading to national reconstruction. The quality of teachers and inputs, therefore become of paramount importance in the whole process of teaching and learning that are influenced by the organizational climate. 221 teacher educators were randomly selected for the study from West Bengal. Organizational Climate Inventory by Chattopadhyaya and Agarwal (2011) and self developed Teacher Educator’s Motivation to Work Scale (2016) was used in the study. It was revealed that the perception of male, self financed and organizational climate of rural teacher educator’s are better than the female, government and urban teacher educators. The female; government and urban teacher educators are highly motivated than the male; self finance and rural teacher educators on their work. There was no positive significant relationship between organizational climate as perceived by teacher educators and motivation to work of teacher educators.

Published: August 2016

In North Kuwait, formation evaluation in horizontal/highly deviated wells typically requires the use of Logging While Drilling (LWD) technology. In this paper, we will discuss how for the first time in Kuwait a state-of-the-art wireline open hole tractor has been successfully used to convey an advanced wireline pressure measurement in a horizontal well. Two wells will be discussed in this paper, the first was a short radius horizontal side track in the tight carbonate formation while the second is highly deviated well across sand/shale layers.

Traditionally in horizontal wells, the pressure measurement is either run on drill pipe or LWD. Moreover, the formation tightness posed another challenge, as stabilized formation pressures can be difficult to achieve. To address the challenge of formation tightness and save rig time, a fast wireline pretest measurement tool allowing dynamic control of the pretest system would be conveyed on wireline using Open Hole tractor. A job simulation was conducted, based on the friction force and tool weight, to ensure the ability of conveying the tractor to the required depth in addition to the ultimate tractor drives number with tandem1 configuration. After gaining confidence and experience from the first well tractoring across tight consolidated carbonate, it was decided to go for open hole tractoring across less consolidated sand/shale layers in a highly deviated well (maximum deviation of 85deg).

Both jobs were successfully executed as per plan. The tool was conveyed smoothly across the tight carbonate reservoir to the target depth of 10,030 ft MD at an average tractoring speed of 1800 ft/hr. The job was concluded with a cumulative tractoring footage of 3200 ft and an operating time of 12.5 hours, which resulted in more than 30 hours of rig time savings compared to other alternatives. The requested pressure program was achieved. Due to the pressure tool's low rate pretest capability, in addition to the flexible volume and pretest time options; stabilized formation pressure data could be acquired2,3. The precise depth control resulting from this conveyance method enabled accurate pressure profiling. Similarly, the second job was conveyed smoothly to the target depth.

The combination of the advanced pressure measurement with a state-of-the-art open hole tractor1 conveyance method has proved to be an efficient and effective alternative to LWD and drill pipe in a challenging horizontal and highly deviated environments (the first job of its kind in the region). It resulted in acquiring accurate pressure data with significant rig time saving, and proved to be a cost effective solution contributing to an overall reduction in the well cost per barrel.

In this study, fluid's density was measured at various temperatures and pressure ranging from 313.15 K to 393.15 K, and 0.1 MPa to 25 MPa, respectively. Meanwhile, fluid's viscosity was measured at temperature between 298.15 K to 373.15 K, and pressure range of 0.1 MPa and 4.48 MPa. In order to understand the effect of reservoir conditions to the density and viscosity of the fluid, experimental data were fitted to several density-/viscosity-temperature-pressure models and then the generated results were statistically evaluated. Based on the results, it is observed that the Tait-like equation was able to satisfactorily express the relationship between the density, pressure and temperature. The predicted density values based on the Tait-like equation are also in good agreement with the regressed model results. For the case of fluid's viscosity, it is found that both modified Mehrotra and Svrcek's and Ghaderi's equation were the best equation for viscosity prediction. Using these equations, it is statistically possible to predict the variation of fluid's density and viscosity over the wide range of pressure and temperature. Furthermore, it is also found that the predicted density and viscosity values are very close to the experimental data with very low deviation. This confirmed the reliability and accuracy of the prediction. This paper provides a novel data prediction of rheology and density of Saraline-based SLWCF at reservoir conditions for the purpose of underbalanced perforation. This result is essential as a tool for field engineers to roughly estimate the density and viscoplasticity of completion fluids as they subjected to reservoir conditions.

Managed Pressure Drilling (MPD), with the installation of Rotating Control Device (RCD) and MPD Choke has been identified as an time saving value added technology to two different operators in Vietnam when mitigating well control situations.

Conventional well control approach is to shut in the annular BOP and circulate out influx by using either the Driller's or Weight & Wait methods. However, these methods can only be used when the bit is on bottom and circulation is possible. In cases when it is unsuitable to use the standard well control methods, alternative such as: stripping to maintain BHP constant plus Volumetric to control gas migration to surface is considered.

Referencing two HPHT wells drilled in offshore Vietnam with MPD equipment; both influxes were encountered when the bit was completely out of the hole and the other when the bit was halfway from bottom of the well. The operators used the RCD bearing assembly and the MPD Choke Manifold to strip the drillstring back to total depth and performed standard well control procedures. The MPD stripping technique allowed the operators to regain well control, enhanced operational safety and significant time savings.

This paper will discuss the methodology of MPD well control techniques based on the experience from the two HPHT wells in Vietnam. The main objectives of the paper is to define, document, and develop workflows to successfully implement well control procedures using MPD in future HPHT wells.

The advances of borehole enlargement (BHE) technology have been a game changer for deepwater well construction in the recent years, allowing larger OD casing strings to reach ever-increasing depths. Among the many reasons why this operation might be required, the potential of a geological structure to have hydrocarbon bearing formations from shallow to deeper depths entails different and challenging operational well construction alternatives, each one with its trade offs. It might be the case that in aiming to strike balance between achieving the formation evaluation goals and allowing a feasible and cost effective well construction, a pilot hole and subsequent hole enlargement strategy might be selected.

This paper presents a case study of two consecutive hole enlargement sections (12-1/4″ × 20″ and 12-1/4″ × 17-1/2″) on a deepwater wildcat well offshore South East Asia. Whilst not a novel procedure, performing such operations in a single run to accommodate large casing sizes in deepwater well construction, working from pre-drilled 12-1/4″ pilot holes, is uncommon. Several challenges associated with drilling dynamics, drilling performance, hole quality and barrier integrity were overcome by the application of hole enlargement technology, rigorous planning and operations workflow.

With the surmounting call of cost cutting measures within the oil and gas industry, it is of paramount importance to examine and evaluate the drilling activities during the course of the application of Managed Pressure Drilling (MPD) technique for High Pressure High Temperature (HPHT) wells globally. The cost reduction has also affected wells drilled in Vietnam.

One common discussion amongst operators to decide on MPD system installation for a drilling campaign is the significant upfront cost associated with the technology. However, through detailed cost benefit analysis and carefully examining the previous lessons learned and extract the best practices in order to apply it for future wells; the benefits in operational safety, drilling optimization, NPT reduction through the use of MPD, significantly outweigh its cost.

The paper will discuss the lessons learned, best practices and experience of MPD technology based on HPHT wells drilled in Vietnam.

Specifically, it will examine what went well on the following: Preparations for MPD in a HPHT environmentMPD equipment requirement and design for the specific MPD applicationRigging upMPD equipmentSelection of sealing element for HPHT wellsHPHT drilling with MPDPumping out of hole vs. pulling out of hole with surface back pressure (SBP)Well control scenario when drill String is out of hole

This Paper describes the challenges and successful application of Inflow Control Devices ("ICDs") combined with sand control screens for horizontal wells. The ICDs were installed to reduce water and gas coning at the Shoba field. Shoba was the first field in Kazakhstan to use ICD technology and the first field in the Pre-Caspian basin where shallow horizontal wells were drilled.

The Shoba field is located within the Zharkamys West 1 block in western Kazakhstan. The Triassic-age sandstone reservoir consists of sweet 34° API oil. The field was initially developed with seven (7) vertical wells. However, high vertical permeability, in combination with high gas and water mobility, resulted in excessive gas and water breakthrough that marginalized the field's economics. An alternate development plan utilizing ICDs and horizontal well technologies was necessary to enhance field commerciality. This project presented numerous challenges. Since the field is relatively small and wells of this type had not been drilled in the region, there was little opportunity for a "learning curve", no margin for excessive cost over-runs, or well failures. Some of the issues overcome that will be presented: ICD design and selection considerationsWellbore instability for shallow horizontal wellsIsolation of a sizable gas cap above the productive oil zonePlugging of the sand control screens during their placementPremature gas or water coning

Shoba's first two horizontal wells were drilled and completed on time and under budget, with early results confirming a reduction of water and gas coning. A significant increase in production rates has also been realized. Given the project's initial success, additional horizontal well development drilling continues.
Proving the Value of Logging-While-Drilling Seismic Technology in a Challenging Offshore Exploration Setting

This paper highlights the value of seismic while drilling to successfully drill a vertical exploration well offshore Malaysia when faced with an expected pressure ramp in the shallow section and a gas chimney in the deeper section disrupting the surface seismic image data.

Using a dual tool Logging While Drilling (LWD) seismic configuration enabled real time Vertical Seismic Profile (VSP) imaging and velocity data for accurate casing point selection, hazard avoidance and successful well construction and enabled elimination of a planned casing string.

The seismic while drilling was conducted from seabed down to final well Total Depth (TD) to acquire a time-depth relationship for the entire wellbore. Acquisition was conducted during connections, an acoustically quiet period when the seismic shots are fired and downhole receivers in the seismic collar are recording. Transmission of the real time data starts when the connection is complete, and the mudpulse telemetry resumes with the drilling. Seismic waveforms sent to surface after each connection were processed for checkshots and VSP image successively after each seismic acquisition level.

Critical 20 inch casing point was accurately set within 20m of identified hazards, despite an initial uncertainty of 100m predrill. The VSP image data was superior to the surface seismic image, recording clear reflectors within a disrupted gas zone, with better phase and frequency content. Full velocity profile over the whole well interval with 15m definition was acquired and processed. The character differed from the initial predrill model and offset well information significantly.

Seismic while drilling removed the need for a pilot hole, and optimized the 20 inch casing point. Accurate real time velocity information allowed for accurate time to depth conversion for drilling decisions i.e. to assist in navigating the shallow pore pressure ramp, casing point setting and providing better seismic imaging in the gas chimney. This case study highlights one of the first applications of real time VSP data enabled by the use of two seismic tools placed 15m apart in the Bottom Hole Assembly (BHA).
