The incidence and clinical features of meconium aspiration syndrome: a two-year neonatal intensive care experience
Authors: FEDAKAR Atiye
Published: December 2018

Objectives: The aim of this present study was to review the clinical characteristics, risk factors, frequency of meconium aspiration syndrome (MAS), development and maternal demographic characteristics of the newborns born with meconium stained amniotic fluid (MSAF) in our neonatal intensive care unit. Methods: The files of the patients hospitalized in our neonatal intensive care unit between July 31, 2015 and July 31, 2017 and who were diagnosed with MAS or MBAS were examined retrospectively. Results: A total of 1410 patients were included during this period. Of these patients, 98 were term infants and 3 (34 weeks) were preterm infants. One hundred and one infants (7.1%) had MSAF and/or MAS. Of the patients, 63 were boys, 38 were girls. MAS developed in 61 patients (60.3%) who were hospitalized due to MBAS. No difference was detected between two groups in terms of the systemic diseases, age, pregnancy number, gestation week, delivery type, length of hospital stay of mother and birth weight of infant. The fifth minute Apgar score and need for resuscitation were found to be statistically significant in patients with MAS. We did not have any mortality. Conclusion: MAS frequency decreases in parallel with the developments in neonatal care but  it is still a major cause of mortality and morbidity. We believe that chance of mortality and morbidity will decrease thanks to the close follow-up and early treatment in infants born with MSAF who are likely to develop MAS.

Higher education is a major factor of modernization of economy and society. Quality and competitiveness of higher education determines the competitiveness of the state in the international space. Internationalization of higher education, which is implemented in accordance with Kazakhstan’s 2011-2020 State Program for Education Development, is one of the priorities of the integration of national education. A major step towards the internationalization of higher education in Kazakhstan is the decision to implement higher education reform along the general lines of the Bologna process. In line with the national plan, the former types and levels of academic programs were transformed into to the three levels established under the Bologna framework: Bachelor, Master and PhD. Along with this, major changes are taking place in the teaching and learning process, the way curricula and programs are organised and delivered. This article discusses the major initiatives in the field of internationalization of higher education in Kazakhstan, such as the state international scholarship "Bolashak", project of the Ministry of Education and Science of the Republic of Kazakhstan aimed at inviting visiting professors, academic mobility students and faculty from the leading universities all over the world.    Keywords: higher education; internalization of higher education; academic mobility;

Operating System Support for IPNoSys
Authors: Fernandes de Araújo Silvio Roberto , Saraiva Silva Ivan
Published: December 2018

The IPNoSys is an architecture that exploits the advantages of NoCs as parallel communication, reusability and scalability to transform the routers in processing elements building a packet-driven architecture that processing while routing the packets. This represents a paradigm break of traditional NoC-based MPSoC systems, which there is the separation between computation and communication. With new paradigm, such architecture already showed superiority in execution time comparing to an equivalent MPSoC. In this paper is presented the operating system support for IPNoSys, including the memory management, process management, I/O management, interruption, exception and timer. Additionally, it is proposed two versions of multi-task scheduling, the first one is a preemptive and the second a non-preemptive. In some cases the scheduling algorithms improvement the throughput of system up to 80%.

SMCV: a Methodology for Detecting Transient Faults in Multicore Clusters
Authors: Montezanti Diego , Frati Fernando Emmanuel , Rexachs Dolores , Luque Emilio , Naiouf Marcelo , De Giusti Armando
Published: December 2018

The challenge of improving the performance of current processors is achieved by increasing the integration scale. This carries a growing vulnerability to transient faults, which increase their impact on multicore clusters running large scientific parallel applications. The requirement for enhancing the reliability of these systems, coupled with the high cost of rerunning the application from the beginning, create the motivation for having specific software strategies for the target systems. This paper introduces SMCV, which is a fully distributed technique that provides fault detection for message-passing parallel applications, by validating the contents of the messages to be sent, preventing the transmission of errors to other processes and leveraging the intrinsic hardware redundancy of the multicore. SMCV achieves a wide robustness against transient faults with a reduced overhead, and accomplishes a trade-off between moderate detection latency and low additional workload.

Published: December 2018

In a globalized world, organizational culture plays an important role in companies since it represents one of the main factors of business success in competitive scenarios. Organizational culture is defined by a set of attitudes, behaviors, norms and beliefs that may guide the life of a company. Organizational values can ensure a common understanding among everyone in the organization, provided that they are shared by all their members. This study describes the results of a systematic literature review on typological model of organizational culture in order to identify organizational values for characterizing the organizational culture in a company. Additionally, we managed a survey to researchers and practitioners analyzing which organizational values are most relevant to a software organization involved with a software process improvement (SPI) initiative. In this paper, we describe forty organizational values identified in the systematic review, and we give particular emphasis in the values the survey results indicate as the main ones that influence the adoption/maintenance of SPI initiatives, i.e., (i) being committed to a high-quality policy for products, services, and processes; (ii) having a well-defined and established vision and goals; and (iii) imposing responsibilities on the team members for meeting deadlines and achieving goals.
Defining Indicators for Risk Assessment in Software Development Projects
Authors: Menezes Jr. Júlio , Gusmão Cristine , Moura Hermano
Published: December 2018

The usage of indicators acts in both strategic and tactical levels, it is effective for optimization of processes and also supports managerial decisions. Despite the relevance of risk management in software projects, it is in fact still usually overlooked by the organizations that develop software. One reason for this fact is that the concept of risk is abstract and subjective, and its management does not bring apparent immediate practical result. Differently, for example, in the financial market, where the risk management is consolidated and widely applied, and it is currently a need for the companies that work in this field. Briefly, risk management practices just became effectively consolidated in the financial market field when the uncertainties became measurable. In this context, this paper aims to define and propose indicators that are specific for environments of software projects in order to support risk assessment activities – risk identification and risk analysis. To achieve this objective, we first developed a systematic mapping study in order to collect evidences about metrics, indicators and relevant information for risk assessment. These findings were combined with the identification of measurable risk factors, providing, thus, a set of categorized indicators for software development environments.
From MoProSoft Level 2 to ISO/IEC 29110 Basic Profile: Bridging the Gap
Authors: Morales-Trujillo Miguel E. , Oktaba Hanna , Ventura Teresa , Torres Rodrigo
Published: December 2018

The spread of the interest and the need for process reference models, specifically for small and medium software development organizations, has been a catalyst for generating ISO/IEC 29110 Software Engineering — Lifecycle profiles for Very Small Entities. Based on the Mexican standard NMX-I-059-NYCE-2005, better known as MoProSoft, ISO/IEC 29110 is the first international standard specifically designed for very small entities.Thanks to the COMPETISOFT Project and MoProSoft, the background knowledge and models adoption experience have been introduced in Latin America. In Mexico more than 300 organizations have been evaluated in NMX-I-059-NYCE-2005, in 2009 MoProSoft became a national standard in Peru, while COMPETISOFT included the experience and viewpoints of 13 countries and 23 research groups of the region. As a whole, it gives small software development organizations in the region an advantage in adopting an international standard.This paper clarifies the gap between ISO/IEC 29110 and MoProSoft level 2. As a result of a theoretical and practical review both standards have been mapped defining the coverage level between processes, considering the defined tasks, work products and roles. Several recommendations have been suggested to bridge the gap between these standards. Finally, the effort needed to adopt the Basic Profile of the new international standard starting from the Mexican standard has been estimated. The results have been extended to also consider organizations that adopted COMPETISOFT as their process reference model.

Are We Prepared for Simulation Based Studies in Software Engineering Yet?
Authors: Nicolau de França Breno Bernard , Horta Travassos Guilherme
Published: December 2018

CONTEXT: Simulation-based studies have been used in different research areas in order to conduct computerized experiments with distinct purposes. However, it seems that Software Engineering simulation studies have been performed in a non-systematic way, using ad-hoc experimental design and analysis procedures, i.e., without defining a research protocol and missing information when reporting results. OBJECTIVE: To characterize simulation-based studies and identify the common simulation strategies in Software Engineering. METHOD: To undertake a quasi-Systematic Review. Three online digital libraries (Scopus, Ei Compendex, and Web of Science) are used as sources of information. Information extraction from the primary studies should be captured using a predefined form. Plotted charts and tables should be used together with quantitative/qualitative approaches when possible to support data analysis. RESULTS: From 946 papers, 108 have been included, from which it is possible to identify 19 simulation approaches, 17 domains, 28 simulation models characteristics, 22 output analysis instruments, and 9 procedures for the verification and validation of simulation models in the Software Engineering context. Most dominant approach is System Dynamics in the Software Project Management domain. Replication is not a common behaviour. CONCLUSION: The lack of information regarding most of the simulation-based studies and their models restricts replication, making the results usually specifics and generalization hard. Apart from that, it compromises validity confidence. More research and discussions should be made by the community to increase the reliability and use of simulation-based studies in Software Engineering.
Energy Consumption of Clocks Synchronization on a Routing Algorithm for Sensor Networks
Authors: Giandomenico Enrique , D’Agostino Estela , Belmonte Javier , Corti Rosa , Martínez Roberto
Published: December 2018

Cluditem is a routing algorithm for wireless sensor networks developed for applications of environmental monitoring with periodic measurement of variables. These applications tolerate a maximum phase shift of the clocks of nodes in the order of milliseconds. This paper proposes two centralized synchronization schemes that introduce a limited processing load. The objective of the work was to assess the impact on the energy consumption of the incorporation of synchronization techniques described. Simulations of the full communication protocol were conducted in the NS2 environment and a comparative study of results was performed. This study showed that the first proposed schema is more convenient with respect to energy consumption, when the area to monitor has reduced dimensions. On the other hand, the second scheme, although it permits to work in larger areas, introduces a decrease in the network lifetime in the order of 14%.
Reviewing the Service Specification of the IEEE 802.16 MAC Layer Connection Management: A Formal Approach
Authors: Morales Ana , Villapol María
Published: December 2018

In most of the communication protocol specification documents, there is little, if any, use of more formal techniques for specifying the protocols, such as state and service primitive tables. Thus, these documents are sometimes ambiguous, difficult to understand, and imprecise. The IEEE 802.16 standard document is responsible for specifying and describing the air interface of the BWA systems (Broadband Wireless Access Systems) point to multipoint fixed and mobile networks, and is limited to the description of the MAC(Medium Access Control) layer and physical (PHY). Since the MAC layer is connection-oriented, the standard defines how the connection management service is provided. The service is specified as the occurrence of a set of well-defined service primitives. However, the description of the service specification is somehow informal and presents some ambiguities and inconsistences. So in this paper, we describe the omissions, uncertainties and discrepancies found in the standard documents and propose some solutions to fix these problems. We also provide a formal description of the connection management service specification using Finite State Automata (FSA).
GPU-accelerated Polyp Detection in Virtual Colonoscopy
Authors: Poó María , Buysse Eduardo , Carmona Rhadamés , Coto Ernesto , Navarro Héctor
Published: December 2018

Nowadays, Virtual Colonoscopy (VC) is an important non-invasive alternative for the study of the colon. Substantial research efforts have been dedicated to this method, and one of the major challenges has always been producing accurate results in a short period of time. One of the most crucial phases of VC is the detection of polyp candidates, where possible lesions on the colon walls are automatically detected. Frequently, this stage requires intensive computations and therefore it is important to develop new techniques for reducing its execution time. This paper presents a technique for automatic detection of polyp candidates based on curvature analysis that reduces the execution time using parallel programming in CUDA. Additionally, we introduce a novel technique for discarding false positive detections based on the shape of a candidate in a planar cut. The obtained results show a remarkable reduction in execution time with respect to a CPU implementation as well as a low rate of false positives.
A volume segmentation approach based on GrabCut
Authors: Ramírez J. Esmitt , Temoche Pablo , Carmona Rhadamés
Published: December 2018

The representation of an image as a flow network has gained an increased interest in research for the 2D and 3D segmentation field. One of these segmentation approaches consists in applying a minimum cut algorithm to separate the image in background and foreground. The most remarkable algorithm to segment a 2D image using this approach is GrabCut. This article presents a novel segmentation of 3D image using GrabCut implemented on the GPU. We proposed a scheme where a volume dataset is used as input, instead of a 2D image. The original GrabCut algorithm is adapted to be executed on the GPU efficiently. Our algorithm is fully parallel and is optimized to run on Nvidia CUDA. Tests performed showed excellent results with different volumes, reducing the computation time and maintaining a correct separation background/foreground.

Authors: Terán Juan , Aguilar José L. , Cerrada Mariela
Published: December 2018

The good performance of a set of computer systems based on agents depends on the coherence degree and coordination between their activities. The study of coordination problem is an important topic for designers and researchers in the multi-agents systems field. There are several coordination mechanisms in the current literature, being the auction and the contract net the most popular ones. These mechanisms allow the agents to allocate resources and tasks to achieve their objectives. This paper aims to present formal models of the auction and the contract net as coordination mechanisms in multi-agents systems based on FIPA (Foundation for Intelligent Physical Agents) Protocols. Mathematical equations describe the different parameters characterizing the auction and the contract net mechanisms; they allow define a generic structure of each mechanism and groups of agents can create several instances of them to coordinate their needs.
The Influence of Process Quality on Product Usability: A Systematic Review
Authors: García-Mireles Gabriel Alberto , Moraga Ma Ángeles , García Félix , Piattini Mario
Published: December 2018

When organizations implement software process improvement programs they are seeking to increase productivity, reduce costs and enhance the quality of the resulting software. In fact, the quality of software products depends, to a great extent, on the processes used for their development and/or maintenance. However, despite this belief concerning the influence of the process on product quality, the specific process-product relationship has been poorly addressed in literature. This paper therefore analyzes the influence that software processes can have on software product usability, which is one of the most important quality characteristics since it influences how the user perceives the product. To this end, we present a systematic literature review examining the relationship between usability and software processes, which has allowed us to identify the processes that relevant studies consider to be important in enhancing product usability.

know the competitiveness of Indonesian cassava if the terms of its competitive
advantage. The basic method used is descriptive analytical method. Analysis of the
data used is the analysis of comparative advantage Revealed Comparative Advantage
(RCA) and analysis of competitive advantage Privat Cost Ratio (PCR). RCA analysis
results for commodities cassava Indonesia has a value of 0.7 or below one, which
means that during the period of cassava Indonesia does not have a comparative
advantage compared to other countries with the same commodity. While the results of
PCR analysis, farming cassava in Indonesia has a competitive advantage because it
has a PCR value of 0.36 or less than one, which means that to get the added value of
farm output by one unit cassava required additional domestic factor costs less than
one unit is equal to 0 , 36. While private profits is positive, it shows that the indication
of the results of farming cassava Indonesia supernormal and should lead to the
expansion or expansion in the future, unless the agricultural areas in Indonesia can
not be expanded or substitute crops are more profitable in private.

 

Abstrak: Penelitian ini bertujuan untuk mengetahui daya saing ubi kayu Indonesia
dibandingkan dengan negara pesaing jika ditinjau dari keunggulan komparatifnya, dan
mengetahui daya saing ubi kayu Indonesia jika ditinjau dari keunggulan
kompetitifnya. Metode dasar yang digunakan adalah metode deskriptif analitis.
Analisis data yang digunakan adalah analisis keunggulan komparatif Revealed
Comparative Advantage (RCA) dan analisis keunggulan kompetitif Privat Cost Ratio
(PCR). Hasil analisis RCA untuk komoditas ubi kayu Indonesia memiliki nilai 0,7
atau di bawah satu, yang berarti pada periode tersebut ubi kayu Indonesia tidak
memiliki keunggulan komparatif dibandingkan dengan negara lain dengan komoditas
yang sama. Sedangkan hasil analisis PCR, usahatani ubi kayu di Indonesia memiliki
keunggulan kompetitif karena memiliki nilai PCR 0,36 atau kurang dari satu, yang
berarti untuk mendapatkan nilai tambah output usahatani ubi kayu sebesar satu satuan
diperlukan tambahan biaya faktor domestik kurang dari satu satuan yaitu sebesar 0,36.
Sedangkan keuntungan privat bernilai positif, hal tersebut menunjukkan bahwa
indikasi dari hasil usahatani ubi kayu Indonesia supernormal dan harus mengarah pada
ekspansi atau perluasan di masa mendatang, kecuali apabila daerah pertanian di
Indonesia tidak dapat diperluas atau terdapat tanaman pengganti yang lebih
menguntungkan secara privat

Abstract: The development of acreage and production of oil in the nationally
decreased 1.17% and 1.54% annually in the period of last six years. Coconut
productivity in one hectare never reaches 1 ton.The low productivity of coconut in the
village of East Mines West Sulawesi province because of old age (30-45 years) and not
cultivated optimally (legacy). The purpose writing papers is a condition of the coconut
in West Sulawesi and coconut derived products what is normally made by the
communities in research and technology are being used to make these derivative
products. Next will be given advice what technology should be used by the coconut
farmers. Products derived from coconut are made and the technology makes it also
unchanged from the first, namely copra, coconut shell charcoal and cooking oil. In
order for the coconut farmers' income can be increased then it is advisable for the
rejuvenation of coconut. Technological changes in line with recommendations made:
(i) copra so that it can increase the water content from 12% to 7%; (Ii) cooking oil
that is produced does not smell and can be more durable (iii) charcoal that produced
containing low water content, still flying high oil content, as well as the holding
capacity of carbon is also high as desired by some industries

 

Abstrak: perkembangan luas areal dan produksi kelapa dalam secara nasional
mengalami penurunan 1,17% dan 1,54% setiap tahun dalam kurun waktu enam tahun
terakhir. Produktivitas kelapa dalam satu hektar tidak pernah mencapai 1 ton.
Rendahnya produktivitas kelapa dalam di Desa Lombong Timur Provinsi Sulawesi
Barat karena usianya yang sudah tua (30-45 tahun) dan tidak diusahakan secara
optimal (warisan). Tujuan penulisan makalah adalah mengetahui kondisi perkelapaan
di Sulawesi Barat dan produk turunan kelapa apa yang biasanya dibuat oleh
masyarakat di lokasi penelitian serta teknologi apa yang dipergunakan untuk membuat
produk turunan tersebut. Selanjutnya akan diberikan saran teknologi apa yang
sebaiknya dipergunakan oleh petani kelapa. Produk turunan dari kelapa yang dibuat
dan teknologi membuatnya juga tidak mengalami perubahan dari dahulu, yaitu kopra,
arang tempurung dan minyak goreng. Agar pendapatan petani kelapa dapat
ditingkatkan maka disarankan adanya peremajaan kelapa. Perubahan teknologi sesuai
dengan anjuran membuat : (i) kopra sehingga bisa meningkatkan kadar air dari 12%
menjadi 7% ; (ii) minyak goreng yang dihasilkan tidak bau dan bisa lebih tahan lama :
(iii) arang yang dihasilkan mengandung  kadar air rendah, kandungan minyak terbang
masih tinggi, serta daya ikat karbon juga tinggi seperti yang diinginkan oleh beberapa
industri.
