Published: November 2020

Assessing writing is a demanding task. If a lecturer of writing is not prepared with a reliable scoring rubric, the studentsâ€™ real performance might not be known. One of the well-known English as a second language (ESL) writing rubric is the Jacobs ESL Composition Profile which was developed by Jacobs, Zingraf, Wormuth,Â  Hartfiel,Â  &Â  Hughey in 1981, known as Jacobs ESL Composition Profile. This scoring rubric is popular among writing teachers and researchers to score studentsâ€™ composition. The present study is intended to 1) find out the internal consistency between raters who use the scoring rubric to assess the studentsâ€™ essay, and 2) describe the level of the studentsâ€™ writing performance when assessed by using Jacobs ESL scoring rubric, and 3) describe the ratersâ€™ opinion when using the profile. The study uses descriptive quantitative design. The instruments to collect the data are documentation and interview. The data were collected in three months, from February to April 2020. The subjects of the study were two writing lecturers who taught English as a foreign language (EFL) and became raters for a research grant. The raters were asked to score 37 essays of the fourth-semester students.Â Â  The result of the study shows that there is internal consistency between rater 1 and rater 2 when scoring the studentsâ€™ essay by using Jacobs ESL Composition Profile is high (r. = 0.674, Î± = 0.00 < 0.05). The Cronbach alpha analysis also shows 0.722 which indicates a strong and high level of consistency. The studentsâ€™ writing performance fall in the average â€“ good (moderate) level (49%), very good (high) level (40%), and only five students (11%) fall in the below-average â€“ poor (low) level category. The result also reveals that Jacobs ESL Composition Profile is considered reliable to score essays even though it requires skills and practice because of its detailed description
Redesigning Face-to-face into Online Learning for Speaking Competence during COVID-19: ESP for Higher Education in Indonesia
Authors: Kusumawati Anggara Jatu
Published: November 2020

During the time of COVID-19, students should study at home and class is conducted fully online. However, classes in higher education are mostly planned for Face-to-Face (F2F) learning. To deal with the situation, educators seek an alternative learning design to be implemented and it is expected to have either comparable or improved learning outcome. This study describes Online Learning (OL) design which assesses speaking performance in ESP classes. The participants of the study were students year 2019 (N=118) and students year 2020 (N=96) joining English for Electrical Engineering (EEE) which has the same syllabus and learning goal. A proposed Gagneâ€™s Nine Events of Instruction is analyzed, planned, implemented, and assessed its effectiveness of speaking activities which were done in the former-year-class (using F2F method) then applied in current class (using OL method). The result of F2F and Online Learning (OL) outcome were compared. To complete the analysis, a sequence of questionnaire was given to the students. The results indicates that using Gagneâ€™s Nine Events of Instruction, speaking activity in online learning classroom, achieved satisfactory result. Designing OL both synchronous and asynchronous method for speaking is as effective as F2F. This study may open another research prospect on barriers in OL, how to assess speaking performance via online platform, or others.

Authors: Ismanto Dodi Robby Hari , Fitriati Rachma
Published: November 2020

The tsunami is the biggest threat to countries around the world tectonic plates and the ring of fire, including Indonesia. The impact of economic losses and heavy casualties made the tsunami worth watching out. Ecosystem-based tsunami disaster mitigation efforts are deemed necessary, considering that 2/3 of Indonesia consists of the sea. The coral reef is one of the coastal ecosystems that can reduce tsunami waves by up to 50% before it hits coastal areas. However, the current condition of coral reefs is very alarming due to the actions of irresponsible humans. Collaboration between stakeholders is needed to carry out ecosystem-based tsunami disaster mitigation efforts. Collaborative governance becomes an essential issue in efforts to build and improve services in the public sector by involving all relevant stakeholders. The sectoral ego of the stakeholders is no longer relevant to be maintained because each actor has their strengths and weaknesses. Collaboration between actors framed in a collaboration platform by having a principled engagement, shared motivation, and collective capacity will produce better results.

Background

Veneto was one of the Italian regions hit hardest by the early phase of the coronavirus disease (COVID-19) pandemic.

Aim

This paper describes the public health response and epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in the Veneto Region from 21 February to 2 April 2020.

Methods

Information on the public health response was collected from regional health authorities’ official sources. Epidemiological data were extracted from a web-based regional surveillance system. The epidemic curve was represented by date of testing. Characteristics of hospitalised COVID-19 cases were described and compared to those never admitted to hospital. Age- and sex-stratified case-fatality ratios (CFRs) were calculated.

Results

Key elements of the regional public health response were thorough case-finding and contact tracing, home care for non-severe cases, creation of dedicated COVID-19 healthcare facilities and activation of sub-intensive care units for non-invasive ventilation. As at 2 April 2020, 91,345 individuals were tested for SARS-CoV-2 and 10,457 (11.4%) were positive. Testing and attack rates were 18.6 per 1,000 and 213.2 per 100,000 population, respectively. The epidemic peaked around 20 to 24 March, with case numbers declining thereafter. Hospitalised cases (n = 3,623; 34.6%) were older and more frequently male compared with never-hospitalised cases. The CFR was 5.6% overall, and was higher among males and people > 60 years of age.

Conclusion

In the Veneto Region, the strict social distancing measures imposed by the Italian government were supported by thorough case finding and contact tracing, as well as well-defined roles for different levels of care.

Oil Saturation Log Prediction Using Neural Network in New Steamflood Area
Authors: Syahputra A.
Published: November 2020

Surveillance is very important in managing a steamflood project. On the current surveillance plan, Temperature and steam ID logs are acquired on observation wells at least every year while CO log (oil saturation log or SO log) every 3 years. Based on those surveillance logs, a dynamic full field reservoir model is updated quarterly. Typically, a high depletion rate happens in a new steamflood area as a function of drainage activities and steamflood injection. Due to different acquisition time, there is a possibility of misalignment or information gaps between remaining oil maps (ie: net pay, average oil saturation or hydrocarbon pore thickness map) with steam chest map, for example a case of high remaining oil on high steam saturation interval. The methodology that is used to predict oil saturation log is neural network. In this neural network method, open hole observation wells logs (static reservoir log) such as vshale, porosity, water saturation effective, and pay non pay interval), dynamic reservoir logs as temperature, steam saturation, oil saturation, and acquisition time are used as input. A study case of a new steamflood area with 16 patterns of single reservoir target used 6 active observation wells and 15 complete logs sets (temperature, steam ID, and CO log), 19 incomplete logs sets (only temperature and steam ID) since 2014 to 2019. Those data were divided as follows ~80% of completed log set data for neural network training model and ~20% of completed log set data for testing the model. As the result of neural model testing, R2 is score 0.86 with RMS 5% oil saturation. In this testing step, oil saturation log prediction is compared to actual data. Only minor data that shows different oil saturation value and overall shape of oil saturation logs are match. This neural network model is then used for oil saturation log prediction in 19 incomplete log set. The oil saturation log prediction method can fill the gap of data to better describe the depletion process in a new steamflood area. This method also helps to align steam map and remaining oil to support reservoir management in a steamflood project.
Cost Effective Permanent Well Plug & Abandon on Cluster-X With Complex Well Conditions
Authors: Biondi B.
Published: November 2020

Regulation PTK-040 SKK MIGAS explained that the oil company must permanently close the wells post-production operations. Cluster-X has complex well conditions, so the observation needs to be cost-effective. The observation on this case refers to SNI 13-6910-2002 explaining the permanent abandonment of wells in the isolation of open-hole zones, perforation zones, blockage of casing stub (junk) as Primary well-barrier and the annular space blockage as a Secondary well-barrier. The next stage is the surface plug as an environmental isolation plug. API BUL E3-FIRST EDITION & NORSOK STANDARD D-010 are also needed for permanent abandonment on surface capping and slotted-liners in multiple reservoirs. Additional references such as API-Spec-10A are needed. The final stage is the testing of cement plugs, hole cleaning process, and budgeting. This paper discusses various conditions of wells on Cluster-X such as abnormally high pressure, cement plug with open-hole slotted-liners in multiple reservoirs, and junk left in-hole. The first step was to run with a balance plug method on ± 10,500-10,971 ft MD as Primary well-barrier. The next step was to run a cement squeeze method with bridge plug on ±7200-7500 ft MD as Secondary well-barrier. On the step of environmental isolation plug a cement plug retainer was run as a weight test with 15,000 pounds the same on previous steps. Type G class cement was selected to cement plug and ran off section milling tools above of the overpressure zone. The wells closure method compares between rigless method coiled tubing unit and portable rig (conventional) which can optimize plug & abandonment operating time and operational cost.
Structural Health Monitoring of An Offshore Platform Trend of Corrosion and Marine Growth With Predictive Maintenance
Authors: Suharto K. S.
Published: November 2020

Nowadays, there are a lot of oil and gas exploration activities all over the world, especially offshore. Oil and gas production itself has many supporting factors in the production process, of which one of them is the offshore platform. Over time, the offshore platform will experience a degradation in strength from the initial design, therefore offshore platforms need to carry out appropriate inspection, maintenance and repair (IMR) programs so that the offshore platform does not reach critical conditions and disrupt the oil and gas production process, resulting in significant losses and not achieving the planned production rates. The offshore platform design is a combination of steel structure and other materials, methods, and loads that are initially worked at the port, such as wave loads, currents, and several other parameters such as gravity, wind, and earthquake. Most of the offshore platforms that currently exist (worldwide) were made in the period of oil investment that developed between 1970 and 1980, thus, the platform's age has now reached 40 to 50 years (El-Reedy, 2012). This research data based on a platform in the Makassar strait between the islands of Kalimantan and Sulawesi. The method used in this research is the platform's design, data observation, data analysis, data processing, and statistical multilinear regression analysis. This research is investigating the degradation trend of the offshore platform and predicting the future of potential failure because of corrosion and marine growth. After the platform encounters degradation over several years, it will decrease the service life before the degradation starts to matter. The results show after data processing that, offshore platforms encounter degradation over several years, and it is presented by a graph containing the condition trend over a multi-year condition because of corrosion and marine growth, and its effect towards unity check (UC) that define structure health. Unity check value produced from allowable stress versus capacity. In this research, structural health monitoring is predicting the potential failure of the platform towards its UC effect of corrosion and marine growth, with a max of the UC value is 0.8 because its a critical value. The failure of the structure possibly would have an affect on the cost-effectiveness. Therefore it is necessary to predict when the structure will fail so that the costs used are effective. Unfortunately, there is no core data for the environmental changes every year at the platform, so the model's equation does not include environmental conditions.

This study will focus on identifying depositional facies in uncored intervals using a gradient boosting classifier, based on electric logs: gamma-ray (GR), resistivity (ILD), neutron porosity (NPHI), and density (RHOB), as well as facies description and classification derived from cored intervals. Supervised learning with gradient boosting classifiers is the primary method that combines a lot of weak learning models to create a robust predictive model. A gradient boosting classifier was applied because the output will be in the form of images. We used nine wells such as four training data, and five testing data along with gamma-ray, resistivity, NPHI, and RHOB as input. The statistical methods were used to distribute facies on each well, and we used the F1 score and average of confusion matrix to validate the values. The result shows 0.718 or 71.8% of the F1 score and 0.6617 or 66.17% of the confusion matrix. With this level of accuracy, we conclude that the gradient boosting classifier methods are reliable enough to determine facies in the area that have limited core data with satisfying efficient results without reducing the accuracy.
Overpressure Identification Using The Eaton Method on The Gumai Formation of Geragai Graben, Jambi Sub Basin
Authors: Marnila A. O.
Published: November 2020

Geragai graben is located in the South Sumatera Basin. It was formed by mega sequence tectonic process with various stratigraphic sequence from land and marine sedimentation. One of the overpressure indication zones in the Geragai graben is in the Gumai Formation, where the sedimentation is dominated by fine grained sand and shale with low porosity and permeability. The aim of the study is to localize the overpressure zone and to analyze the overpressure mechanism on the Gumai Formation. The Eaton method was used to determine pore pressure value using wireline log data, pressure data (RFT/FIT), and well report. The significant reversal of sonic and porosity log is indicating an overpressure presence. The cross-plot analysis of velocity vs density and fluid type data from well reports were used to analyze the causes of overpressure in the Gumai Formation. The overpressure in Gumai Formation of Geragai graben is divided into two zones, they are in the upper level and lower level of the Gumai Formation. Low overpressure have occurred in the Upper Gumai Formation and mild overpressure on the Lower Gumai Formation. Based on the analyzed data, it could be predicted, that the overpressure mechanism in the Upper Gumai Formation might have been caused by a hydrocarbon buoyancy, whereas in the Lower Gumai Formation, might have been caused by disequilibrium compaction as a result of massive shale sequence.

Published: November 2020

Pharmacognostic investigation involving organoleptic evaluation, fluorescent analysis, phytochemical screening and mineral analysis was carried out on the dried powdered leaves of Allophylus africanus used for treating pain, headaches, common cold, Fever and as antibiotics in Eastern Province of Sierra Leone. The powdered leaves were light brown in colour with woody odour, bitter taste and gave significant fluorescent derivatives with the reagents 1M NaOH (aq), 1M NaOH(alc.), Ammonia, 50% HCl, and 50% HNO3 when viewed under ordinary visible light and ultraviolet light. The plant organ investigated during phytochemical screening gave positive for carbohydrates and reducing sugar, Amino acids and Proteins, Alkaloids, tannins and phenolic compounds, saponins glycosides Flavonoids, sterols/terpenes and triterpenes all of which have been reported to be pharmacologically active compounds responsible for the medicinal use of Allophylus africanus plant.

Elemental analysis of the plant organ was performed with a Niton XL3t GOLDD + Hand held X-ray Fluorescence (Thermo Fisher) and the results indicated that the plant organs investigated contained large amounts of K, Ca, Mg, Al and Fe whilst Ti, Zr, Mn, Zn, Sr, Sc, Rb, Cu, V and Mo were present in minute quantities. The presence of the above elements also support the use of the plant organ investigated as food and medicine.

The compounds LK003 isolated from the ethanol extract of the dried powdered leaves of the plant and structure identified using fragmentation patterns from LCMS, Proton NMR spectroscopy and by McLafferty rearrangement as N-(3-methoxyphenyl) acetamide called phenacetamide which has been reported to be a clinically tested drug for pain and fever. Hence, we concluded in this research work that the presence of N-(3-methoxyphenyl) acetamide called phenacetamide, the secondary plant metabolites and minerals present in the dried powdered leaves traditional medicinal plant Allophylus africanus support the use of the plant as a traditional pharmaceutical.
Hakkâri İlinde Gezgin Arıcılık Faaliyetleri

Published: November 2020

Hakkâri’deki gezgin arıcılık hareketlerinin yönünü, yoğunluklarını ve bazı arıcılık faaliyetlerini belirlemeyi amaçlayan bu araştırmada, Hakkâri’ye farklı bölgelerden gelen 52 ve Hakkâri’den giden 100 olmak üzere toplam 152 arıcı ile yapılan anketlerden elde edilen veriler değerlendirilmiştir. Araştırmada, Hakkâri’ye gelen arıcıların % 40.00’ının Hatay, % 28.85’inin Adana ve % 19.23’ünün ise Şanlıurfa arıcıları olduğu belirlenmiştir. Çalışmada, nektar akımı başlangıcından itibaren kolonilerini nakletmeye başlayan arıcıların büyük çoğunluğu (% 34.62) Hakkari'ye Mayıs ayının son haftasında gelmekte iken, kolonilerini ılıman bölgelerde kışlatmayı hedefleyen Hakkârili arıcıların % 48.00’inin yöreden eylül ayı ortasında ayrıldığı sonucuna varılmıştır. Nektar kaynaklarından daha fazla yararlanmayı sağlayan gezgin arıcılık, yakın zamanda arıcılığın temel gereklerinden biri haline gelmiştir. Bununla birlikte denetimsiz melezlenmelere sebep olması nedeniyle yerel genotiplerin kaybolması gibi olumsuzluklara bağlı olarak, koloni hareketlerinin kontrol altına alınması zorunluluk arz etmektedir. Bu bakımdan sunulan bu çalışma sonuçları, yöre için koloni hareketlerinin düzenlenmesine yardımcı olabilecek niteliktedir.
Una propuesta de traducción de textos legislativos vigentes en México a lenguas indomexicanas, a partir del trabajo con purépecha
Authors: Hernández Domínguez Rolando
Published: November 2020

En México, el acceso a la justicia de los pueblos indígenas pasa por la traducción de los textos legislativos vigentes en español a las lenguas indomexicanas. En la actualidad, la traducción se caracteriza por esfuerzos aislados carentes de un método de traducción adecuado. El propósito de este texto es dar a conocer una propuesta de traducción a la lengua purépecha que abreva de lo lingüístico, lo jurídico y la traducción, y mostrar los resultados de su aplicación. Se apela a la traducción colectiva de un equipo multidisciplinario para generar un texto con pertinencia en la lengua meta. Esto implica considerar no sólo el tránsito de una lengua a otra, sino la conciliación de los elementos culturales subyacentes a cada sistema lingüístico.

Link between periodontal inflammatory disease and Parkinson’s disease: Case reports
Authors: Ivan Minić  , Ana Pejčić  , Sanja Popović
Published: November 2020

Parkinson's disease (PD) is caused by a loss of nerve cells in the part of the brain called the substantianigra. Nerve cells in this part of the brain are responsible for producing a chemical called dopamine. The symptoms of Parkinson's disease usually only start to develop when around 80% of the nerve cells in the substantianigra have been lost. Uncontrolled severe periodontitis caused by periodontal pathogens represents a major infectious threat to the entire body, since released toxins and other inflammatory mediators can reach and affect distant organs. Until now, periodontal disease and Parkinson's disease has been linked only on the basis of poor motor and cognitive control in Parkinson's patient which leads to poor oral health maintenance. Evidence now suggests that chronic neuroinflammation is consistently associated with the pathophysiology of Parkinson's disease. Also, recently, systemic inflammation has been suggested as one of the contributing factors for neurodegeneration. The local inflammatory responses at the site of infection are often linked to CNS disorders such as Parkinson's disease. Infections in the oral cavity, untreated conditions, foci can contribute to the worsening of Parkinson's disease. It is concluded that it is necessary to repair the oral cavity in all patients in order to achieve possible improvement, and on the other hand in these patients it is necessary to fully rehabilitate the oral cavity due to daily functions of the oral cavity which are difficult due to the clinical condition.
