Enhance Seismic Quality With A Fast, Robust and Economic Solution Using Broadband Technology
Authors: Syarif M.
Published: November 2020

Often many companies doing seismic reprocessing project with the latest advanced seismic processing technology to handle their seismic problems. This kind of solution might work for some companies but certainly will not for many others. Innovative solutions are required to overcome seismic problem or issue considering time, budget and technical robustness. The objective of this paper is to demonstrate a seismic processing project that was run in a relatively low oil price condition, to handle a low seismic resolution problem in thinly bedded reservoirs. In addition to budget and technical constraints, timing and schedule is also an issue since the updated interpretation is required to be used for updating a static model in less than a 3 months time window. A broadband processing method on 100 km2 post-stack 3D seismic data was applied to enhance frequency content which leads to enhanced seismic resolution to resolve objective reservoirs. This method is considered fast, robust and economical. The procedure would be enhancing the spectrum by designing a unique filter into the dataset after inverse Kirchhoff migration application. After some iterations, forward Kirchhoff migration and multi spatial time-variant filter was applied to generate the desired output. Overall processing time was completed within budget in a one-month period only. As a result, forty percent (40%) increase in dominant frequency was achieved as final deliverables from 25Hz to 35Hz. The original dataset with 25Hz dominant frequency can only resolve reservoirs with thickness greater than 20m. The thickness of individual objective sandstone reservoirs in the study area was ranging from 1.5m to 20m with average thickness around 6-10m. However, stacked reservoir thickness within the same flooding surface interval of the same unit is relatively thicker than 10m. The 35Hz dominant frequency data from broadband processing can resolve reservoir with thickness greater than 14m and better resolve stacked reservoirs even though very thin reservoir below resolution remains unresolved. Broadband seismic technology on post-stack dataset offers a fast, robust and economical solution focused on target which can be duplicated in other area/data to provide successful interpretation projects.
Integrating Wireline Logs and Seismic Data to Analyse The Facies snd Paleogeography of Tanjung Formation, Barito Basin, South Kalimantan
Authors: Rosa E. A.
Published: November 2020

The study area is physiographically part of the Barito Basin, South Kalimantan (Van Bemmelen, 1949). 2D seismic data along with well logs from three wells, biostratigraphy data from two wells, and core data are utilized to do an integrated sequence stratigraphy. Petrography data from the equivalent formation at well-X from the study area is also used to support the evaluation. This study was to determine lithology facies and depositional environment based on several key maps: Sand Shale Ratio (SSR), Isopach, and Paleogeographic Maps. After that, seismically-supported sequence stratigraphy was applied to vertically and laterally subdivide the facies distribution and paleogeography into two depositional models based on the following key sequence-stratigraphic markers: (1) Sequence Boundary (SB)-1 to SB-2 that show regressive succession, and (2) SB-2 to Top Tanjung Formation that reflects transgressive phase.
Analysis of Fisheries Support Estimate for Sustainable Blue Economy
Authors: YILMAZ Özlem
Published: November 2020

The Blue Economy concept was firstly introduced after 2008 Mortgage Crisis, and gained importance in the United Nations Sustainability Conference held in Rio in 2012. In this study, the concept and the scope of the blue economy are given, and the fishing activity, which is one of the crucial blue economy components, is emphasized. According to the Food and Agriculture Organization (FAO) reports, fish stocks are decreasing due to overfishing in the world. It has been suggested that fisheries support is leading to overfishing and to the reduction of fish stocks. The purpose of this study is to analyze whether fisheries support causes overfishing and whether it is a problem for sustainable fish resources. In the Python program, a production model was estimated to analyze the relationship between fisheries production and fisheries support, the number of vessels and the number of fishermen in 37 countries between the years 2012 and 2017. According to the model, it was observed that the fisheries support, the number of vessels and the number of fishermen increase fish production, but there is not a high correlation between the variables. In order to remove the overfishing pressure on fish production, it is important to shift the fisheries support to the support types which are indirectly related with the fish output.

Acinetobacter baumannii as a causative agent of health care associated infections
Authors: Miguel Ángel Aguirre Navarrete  , Rocío Pérez y Terrón
Published: November 2020

Acinetobacter baumannii is an opportunistic pathogen that seriously affects sick patients, causing Health Care Associated Infections (HCAI) such as pneumonia associated with mechanical ventilation, urinary tract infections and bacteremia, in recent years this bacterium has become a health problem worldwide, its isolation from infections present in hospitalized patients has been increasing, and it also has various mechanisms of resistance to antibiotics. The present documentary research aims to describe the mechanisms of pathogenicity and resistance to antibiotics used by Acinetobacter baumannii as a causal agent of HCAI. To carry out this work, a literature search was carried out in databases such as: Scielo, PubMed, NCBI, and Elsevier. The pathogenicity mechanisms that allow it to colonize and develop infections in hospitalized patients are: porins, biofilms, pili, lipopolysaccharides, phospholipases, outer membrane vesicles and the production of siderophores. It has enzymatic resistance mechanisms such as beta-lactamases and non-enzymatic mechanisms such as porin modification, efflux pumps, and modifications in DNA gyrase. There are extrinsic factors that favor the development of HCAI, such as the immunological and health condition of the patient, as well as the association with medical equipment. Studies carried out between the years 2005 to 2018 reveal that A. baumannii is one of the main causative agents of pneumonia associated with mechanical ventilation in patients admitted to the Intensive care unit.

Presently, Short Tandem Repeats (STRs) based forensic DNA typing technology is being globally used in solving a diverse range of forensic cases such as paternity, identification of unknown dead bodies/skeletal remains, or suspect in a case of rape or mass rape. The technology has invaded its tentacles in almost all areas of criminal investigation in the last few decades. The present forensic DNA technology is based on capillary electrophoresis and utilizes short tandem repeats(STRs).On one hand, the technology is extensively used in the investigation of crime in highly sensitive cases, but on the another hand, obtaining DNA profile from forensic samples are highly challenging many times. Advent of PCR has been a boon for handling the challenging samples in forensic DNA analysis. The quality DNA profiles from challenging samples rely on the yield and quality of DNA, which is mainly dependent upon the method used for DNA extraction. Any specific method can never be thought of to be useful for all variety of samples. Still, Phenol Chloroform Isoamyl Alcohol (PCIA) organic extraction method has been proven to be useful for a wide variety of samples from the simplest saliva/blood to complex teeth and bone samples. In the present study, we compared the yield of DNA from blood stains recovered from various surfaces using the PCIA extraction method and Chelex DNA extraction methods and their compatibility with present-day STR based capillary electrophoresis typing. The mean value of DNA yield was found 50.5 ng/ µl and 32.25 ng/ µl by PCIA and Chelex DNA extraction methods, respectively. Overall, the highest yield was observed from all the tested samples from the PCIA method.

Published: November 2020

In recent years, experience of students in technology-equipped laboratories has been seen as an effective way to teach and learn physics. In this sense, experiments and demonstrations using computer based data collection systems and simulations that allow students to design their own virtual experiments in the physics laboratory come into prominence. In this study, the usage of computer based laboratory and virtual laboratory applications in the physics laboratory are discussed. In this context, the effects of computer based laboratory applications and virtual laboratory applications on students' graph drawing, understanding and interpretation skills, attitudes towards the physics laboratory and motivation for learning science were investigated. Sixty university students participated in the pre-test post-test semi-experimental design study. While the control group carried out experiments on the laws of motion with computer based laboratory, the experimental group performed the same experiments with virtual laboratory applications. The data of the study were collected through attitude scale, motivation scale and graph drawing, understanding and interpretation test. Independent sample t-tests were used in the analysis of the data. The findings show that computer based laboratory practices are more effective in the development of students' ability to draw, understand and interpret graphics than virtual laboratory applications. It has been determined that both computer based laboratory and virtual laboratory applications have a positive effect on students' attitudes and motivations. Also, computer based laboratory applications were found to be more effective in increasing students' motivation levels for communication, collaborative work, and participation than virtual laboratory applications. The findings of the study suggest that computer based laboratory applications in physics laboratories are more effective than virtual laboratory applications.
Design, Implementation and Students’ Emotional Assessment of a Software for the Learning of Rational Numbers through Music Metaphors in Chilean Primary Education: An Exploratory Study on Audio Fractions
Authors: Thayer Tomas , Venegas-Thayer M.Alicia , Tejada Jesus
Published: November 2020

Using sound and music as a metaphor to approach curricular mathematical contents in Primary Education seems an interesting field that deserves some research. Both music and sound can synergically act as scaffolding for learning, intervening as part of situated knowledge, and they could offer a new perspective for learning mathematics at schools, giving pupils opportunities to develop their own mental representations. Also, the incorporation of an affective/emotional analysis, as criteria for evaluation, seems pertinent and complementary to other criteria in the production of multimedia material with educational purposes both in formal and non-formal domains of education. These are the intentions of the present work, which shows the design, implementation and assessment of AudioFractions, as part of an educational software package called Sound Interactive Music-Mathematics, which was conceived to aid mathematical learning through sound and music in Chilean Primary Education. The investigation was carried out in a three-stage design: 1) generate significant metaphors; 2) implement and test functional software prototypes and didactic guidelines; and 3) assess the software. Pupils in risk of social exclusion at three priority public schools in Santiago de Chile (N=137; 9-11 years old) were subjected to AudioFractions in one 60-minute session. Then, students filled a questionnaire validated by experts with their perceptions about the software and their emotions. Results of the four assessment variables (global, technical, mathematical, musical) plus an affective-emotional assessment, show an excellent reception of AudioFractions

Authors: Wilkinson Kerry , McNamara Imogen , Wilson David , Riggs Karina
Published: November 2020

This case study describes the use of learning analytics to evaluate the transition of a postgraduate wine business course from face-to-face to online delivery using e-learning course design principles. Traditionally, Foundations of Wine Science lectures were delivered face-to-face, however the decision to transition the course from semester to trimester format presented an opportunity for online delivery of lectures. This was initially achieved through audio recordings, then video lectures, supported by a range of digital learning resources intended to engage, support and enhance student learning and the student experience. Descriptive analysis of learning analytics, comprising assessment results, student evaluations of learning and teaching, and data sourced from the Learning Management System, was performed to evaluate the impact of online delivery of course content on student performance, satisfaction and engagement. The use of audio lecture recordings negatively impacted students’ perception of the overall quality of the course (including course organisation, learning strategies and learning resources). The subsequent implementation of e-learning designed video lectures was considered superior to audio recordings, albeit final grades were not significantly different between the delivery modes. However, student engagement was equal to, or better than face-to-face delivery, when content was designed specifically for an e-learning environment.

Teachers play an essential role in the evaluation of learning materials. As facilitators of learning, they ensure that learning materials serve their purpose of bringing about the effective teaching-learning process. This study aimed to evaluate the Department of Education (DepEd)-produced Grade 7 Biology Modules as perceived by Biology Experts and Science Teachers in the 16 public secondary schools in the Division of Tacloban City, Leyte, Philippines. The modules are evaluated based on the seven dimensions: a) content, b) presentation and organization, c) learning activities, d) evaluation activities, e) accuracy and up-to-dateness of information, f) format and g) sufficient availability of materials. The demographic profile of 17 Biology experts showed that the majority are female, BSED graduates in Biological Sciences with a doctoral degree in Biology and 1-15 years teaching Biology subjects. Grade 7 Science teachers are mostly females who have a bachelor's degree in Biological Sciences, with master's units and 1-2 years teaching Grade 7 Science in the K to 12 Curriculum. Biology experts and science teachers assessed the five modules using descriptive survey method employing quantitative and qualitative analysis. They both evaluated the modules satisfactory in the seven dimensions. However, they pointed out suggestions for improvement of the modules.

Published: November 2020

This study examines the impact on academic success of two different models of teaching for repeating students. Students who failed in 2017 under the traditional model of teaching, involving a 12 week semester with lectures and tutorials, were exposed the following year to the newly introduced “block model” of teaching, whereby students study one unit at a time over 4 weeks in small classes. Repeating students who had previously failed the same unit were asked to complete a questionnaire online, which elicited their perceptions of the two different teaching models. In addition, data was extracted from the university’s central database to compare the success rate of failing students on their second attempt under the different teaching approaches. Results show a significant improvement in grades and pass rates with this new intensive block model of teaching along with positive student perceptions toward this more intensive, workshop based teaching method.

Published: November 2020

The current study explored mathematics perceptions of teachers and high school students. The online survey consisting of three open-ended questions was answered by 104 high school students and 92 mathematics teachers. A qualitative descriptive research approach was applied to analyse the data. The results of this study showed that mathematics is seen as a branch of science, everything, explanations of concepts with numbers, language, universal language, language of nature, language of universe, life, method, numbers, and tool. Moreover, it was found that there are differences in perceptions between students and teachers as well as males and females. The results of this study extend what we know about student and teacher perceptions of mathematics and add an important contribution to mathematics education research.

Published: November 2020

We describe the rationale, creation, and activity of a long-term co-constructed voluntary professional development initiative for tertiary educators. This is a Community of Practice (CoP) formed to investigate “thinking” as a topic which may be explicitly taught. The aim of this paper is to share the value of this CoP in one context and insights into how similar approaches may be useful to other tertiary educators. The project has run for a year to date, involving a small but growing collective of tertiary educators, with members from one Canadian and several Australian Universities. Our methodology is participatory: we regularly meet, reflect, and record our reflections. Our records contain data relating to our motivation, our insights, and the impact of these upon our choices in our teaching practices. In particular, our rationale includes the mutual desire to invest in developing understanding of our teaching challenges, to enable us to create thoughtful teaching approaches fit for our purposes and contexts. Hence, the central focus of our CoP is the Development of our Expertise in Fostering Thinking (DEFT). This focus has illuminated gaps in existing scholarly literature pertaining to communal development of theory, personal development of schemata, capacity for reflexivity, and instantiation in our disciplines. Opportunities and risks associated with our other sources of professional learning are identified and discussed. We elaborate on a double-layered approach, in which we explore the construction of our own schemata as a precursor to helping students build their schemata as a foundation for their own understanding, and the role of flexible, critical, and creative thinking on our part. We utilise the scholarship of expertise, frequently returning to such questions as “How do we know what our students are thinking?” Insights gleaned from our reflections are shared, and recommendations are presented on the formation of similar projects.

Teachers as educators are often in a dilemmatic position, between the demands of the profession and community treatment. Teachers are required to be able to deliver students to achieve educational goals. However, when teachers try to punish students in order to enforce discipline. spontaneously parents and society categorize it as an act that violates human rights and child protection laws. The formulation of the problem in this study are: First, how to protect the rights of teachers in disciplining students? Second, Has the Court Decision related to the teacher's efforts to discipline students provided protection for teachers or vice versa? The research method used is to use the normative legal method. The theoretical framework used is to use the theory of legal protection developed by Satjipto Rahardjo. The conclusions generated in this study: First, in the context of the dialectics between norms that meet each other, a legal synthesis appears through the presence of the Supreme Court's Decision which is able to provide protection for teachers. Second, that the Supreme Court Decree No. 1554 K / PID / 2013 has been able to provide optimal protection for teachers to carry out their functions as educators.

It has been nineteen (19) years of special autonomy imposed in the land of Papua. But the problem of education in Papua and West Papua is not something new to hear. Papua and West Papua still rank 31 out of 34 provinces in Indonesia. Policies to improve the quality of human resources of Papuans are an important part of the framework for bringing prosperity to all Indonesians. This study uses a descriptive qualitative method. To see the results of the policy evaluation researchers used the theory of evaluation according to Willian N Dunn on four (4) criteria namely; Efficiency; Effectiveness; Leveling out; Responsiveness. Research Results: 1. The education budget allocation of 20% of the APBD is only 13% which has been realized, around 7% that has not been implemented. 2. Undergraduate Scholarship Program, Teacher Welfare Program, and Dropout Rate Program, which is implemented by the City Government of Sorong, has been running well. But there is no clear budget transparency from the Government related to these education financing programs. 3. Every year around 200 indigenous Papuan students are given scholarships. Teacher welfare has been noted but is not guaranteed. Weak economic students are given tuition fees. 4. The implementation of the education funding program by the City Government of Sorong is still unknown by all Sorong city residents, lack of socialization and some programs are still closed. Otonomi khusus sudah diberlakukan di tanah Papua selama sembilan belas tahun lamanya. Tetapi, masalah pendidikan di Papua dan Papua Barat bukan sesuatu yang baru untuk didengar. Papua dan Papua Barat masih menempati peringkat ke-31 dari 34 propinsi di Indonesia. Kebijakan untuk meningkatkan kualitas sumberdaya manusia Papua menjadi bagian penting dari kerangka kerja untuk membawa kesejahteraan bagi seluruh rakyat Indonesia. Penelitian ini menggunakan metode deskriptif kualitatif. Untuk melihat hasil evaluasi kebijakan, peneliti menggunakan teori evaluasi menurut Willian N Dunn pada empat (4) kriteria: Efficiency, Effectiveness, Leveling out, dan Responsiveness. Hasil Penelitian menunjukkan: pertama, alokasi anggaran pendidikan sebesar 20% dari APBD hanya 13% yang telah terealisasi, sementara sekitar 7% belum dilaksanakan. Kedua, Program Beasiswa Sarjana, Program Kesejahteraan Guru, dan Program Angka Putus Sekolah, yang dilaksanakan oleh Pemerintah Kota Sorong, sudah berjalan dengan baik meskipun tidak ada transparansi anggaran yang jelas dari pemerintah terkait program pembiayaan pendidikan. Ketiga, sekitar 200 siswa sudah mendapat beasiswa setiap tahun. Kesejahteraan guru telah dicatat meskipun tidak ada jaminan, sementara siswa dengan ekonomi lemah diberi biaya kuliah. Keempat, implementasi program pendanaan pendidikan oleh Pemerintah Kota Sorong masih belum diketahui oleh semua warga kota Sorong, terutama karena kurangnya sosialisasi dan beberapa program masih ditutup.

The implications of prosocial behaviour on public service motivation are found. The link between prosocial behaviour and public service motivation from a sense of wanting to help others. In practice, civil servants are often encouraged to help the community. The meeting point between public service motivation and prosocial behaviour is with the choice to become a volunteer. Civil servants who have a robust public service motivation will be involved in voluntary activities. This study aims to examine the effect of volunteerism on the motivation of public services on civil servants in Yogyakarta special government. The method used in this research is quantitative research methods. Questionnaires are distributed at special local government offices in Yogyakarta that provide basic services. The number of respondents who answered the survey was 321 people. Data processing using SEM PLS and data analysis using quantitative descriptive. The results of this study are prosocial behaviour and the value of altruism through voluntarism activity significantly influence the motivation of public services. But directly, prosocial and altruism do not affect public service motivation. Perilaku prososial berimplikasi terhadap motivasi pelayanan publik. Hubungan antara perilaku prososial dan motivasi pelayanan publik timbul dari rasa ingin membantu orang lain. Dalam praktiknya, pegawai negeri sering didorong untuk membantu masyarakat. Titik temu antara motivasi pelayanan publik dan perilaku prososial adalah dengan pilihan untuk menjadi sukarelawan. Pegawai negeri yang memiliki motivasi pelayanan publik yang kuat akan terlibat dalam kegiatan sukarela. Penelitian ini bertujuan untuk menguji pengaruh kesukarelaan terhadap motivasi pelayanan public pada pegawai negeri sipil di Daerah Istimewa Yogyakarta. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif. Kuisioner disebar di kantor-kantor pemerintah Daerah Istimewa Yogyakarta yang menyediakan layanan dasar. Jumlah responden yang mengisi survei adalah sebanyak 321 orang. Pengolahan data menggunakan SEM PLS dengan teknik analisis data deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa perilaku prososial dan nilai altruisme melalui aktivitas voluntarisme berpengaruh signifikan terhadap motivasi pelayanan publik.

Resource use efficiency is the extent at which a firm or production unit makes proficient decisions by utilizing limited resources to maximize profit. Elasticity of production is a measure of a firm's success in producing maximum output from a set of input. This research analyzed resource use efficiency and elasticity of production among smallholder broiler producers in Ikwuano LGA of Abia State, Nigeria. Specific analytical techniques employed was the production function analysis involving the four functional forms of linear, double log (Cobb Douglas), semi-log and exponential. This was used to obtain the parameters for the measurement of resource use efficiency among the broiler producers. The results of the analysis shows that resource use efficiency (r) was 1.064, 0.018, –0.046 and 0.049 for quantity of broiler produced (stock size), labour expenses, cost of medicines/drugs and feed expenditure respectively. Stock size and feed expenses had the highest efficiency index of 1.064 and 0.049. The least efficiency index was recorded for medicines/drugs with a negative value of –0.046 which implied that the resource use efficiency for medicines/drugs was grossly inefficient. The resource use efficiency for stock size/quantity of day-old-chicks shows that the resource was completely over used. The resource use efficiency with which poultry feeds were utilized shows that the quantity of feeds was over utilized. The elasticity of production of the smallholder broiler producers was 1.016 (ΣEp>1). This shows that, if all resources were to increase by 100%, output would increase by 101.6%. This implies that fixed resources (land, depreciated equipment) were abundant relative to variable resources (feed, day-old-chicks, medication and labour); yet, these fixed resources were not efficiently utilized due to lack of sufficient quantity of variable resources. There is a paramount need to increase variable resources in order to maximize profit.

Authors:   A. A. Movchan Institute of Applied Mechanics, Russian Academy of Sciences, Movchan A. A.
Published: November 2020

A combined model of inelastic deformation of shape-memory alloys for phase and structural transformations is proposed, taking into account the fundamental difference between these two mechanisms and the influence of the first mechanism on the second. In contrast to the known analogs, the model allows for non-monotonic loading processes to exceed the long arc of phase-structural deformation (an analogue of the Odqvist parameter in the theory of plasticity) of the intensity of crystallographic deformation of the phase transition.
