Published: June 2019

The objective in this study was to evaluate the spatial and temporal variability of the beverage quality by applying the fuzzy classification in the final global sensory analysis, for Coffea canephora Pierre ex A. Froehner, in two consecutive harvests. The studied variables were: fragrance (aroma), flavor, bitterness (sweetness), set, balance, cleaning, aftertaste, mouth feel, uniformity, salinity (acidity) and drink (global note). To the average overall scores of the drinks obtained on the cup-tasting at 80.0 points of a sampling, the mesh has applied the function of association of the fuzzy classification linear model to determine the degree of pertinence. The data were analyzed by the descriptive statistics and then by geostatistics to verify the existence and quantify the degree of spatial dependence of the variables. In the interval classified as “very good coffee” is found in the global average grade, in the two harvests. The methodology fuzzy applied in the global beverage note of the coffee conilon seminal made it possible to determine their spatial variability in the same distribution pattern in the two harvests, close ranges, and adjustments to the spherical model, which was confirmed by the spatial correlation of 61.6% among the fuzzy maps for the global score

The objective of this study was to select coffee progenies with better assessment that can result in coffee rust resistant cultivars and better agronomic characteristics than the traditional ones. The essay was performed at the EPAMIG experimental field in Patrocínio, state of Minas Gerais, Brazil. Twenty-five progenies in the F3 generation were studied.  The experiment was set in a randomized complete block design with three replicates and ten plants per plot, arranged in rows at 3.5x0.7m. Productivity assessment, fruit production, in liters of “farm coffee” per plot, bean rating in a sieve (16 or above), and plant vigor were accessed in three different harvest seasons (2011/2012 harvest to 2014/2015 harvest), and coffee rust incidence and severity were then evaluated for 2016. The production profit estimation through the selection was also assessed, by the gain of direct selection for each characteristic, when compared to the rank addition. Progenies 13 (Icatu V. IAC 4040 x IAC 5002) and 3 (Icatu A. IAC 2944 x IAC 5002) were promising in generation advance, for being among the five most productive progenies. The selection gain reached by direct selection was superior than the gain of the total rank additions.

Published: June 2019

The use of portable brush cutter may expose workers to localized vibrations, from the transfer of mechanical vibration of the tool to the operator’s hands and arms. With this in mind, the objective in this study was to quantify the levels of occupational vibration transmitted to the hands and arms of the portable brush cutter operators under routine working conditions in the coffee crop. The vibration levels transmitted to the operator’s hands were measured during activity with portable brush cutters. The experimental design was completely randomized (CRD) in a factorial scheme (2 x 2) combined with two types of grip (Circular cable (CC) and double grip handle (DGH) with two types of tip cutting blades (2TB and 3TB). The data acquisition occurred from the use of the vibration meter SV 103, SVANTEK with triaxial accelerometer, installed on each of the worker’s hand at the contact point with the tool. The results demonstrated that the 2.5 ms-2 action level determined by NR 09 and NHO 10 was exceeded under all conditions of the present study. The highest accelerations were quantified in the operation of the brush cutter equipment with CC, reaching the daily exposure limit of 5 ms-2 allowed for an 8-hour of working day. The resulting acceleration of the DGH equipment was on average 37.45% lower than the operation with the CC equipment. The results bring indicatives of occupational advantages in the selection of these types of accessories for brush cutters, in order to mitigate the effects of exposure to HAV in extended use situations

Published: June 2019

Despite the great diversity of available Arabica coffee cultivars it is observed that, even when presenting different phenotypes of interest, new cultivars are adopted at a slow pace by coffee growers. One possible reason may be the lack of information on the performance of these genotypes in different regions and culture conditions. The aim this work was to verify the performance of twelve coffee cultivars in relation to morphoagronomic characteristics at initial stage of development, as well as the beans quality, in a condition of typical cultivation of the Cerrado. The trial was carried out in the municipality of Monte Carmelo - MG, in randomized block design, with four replicates. Morphoagronomic characteristics were evaluated 15 months after the implantation of the crop. The productivity and, subsequently, the quality of the beans, were evaluated at 18 months. Statistical analyzes were performed using the Genes software. The data were submitted to analysis of variance. The F test was used to determine the significance of treatments. The means were grouped by the Scott-Knott test (1974) at 5% probability and the experimental precision was verified by the estimation of the experimental variation coefficient (CV) and the selective accuracy. The sensory attributes were evaluated in a radar diagram, called “Sensogram”. Genetic variability was observed among cultivars for the vegetative characters. The cultivars Catuaí Vermelho IAC 144 and MGS Aranãs stood out as more productive, with a high percentage of sieve 16 and above and low percentage of grain type mocha. All the cultivars stood out as special, with emphasis on the cultivar Bourbon Amarelo IAC J10 in the wet processing and Catuaí Vermelho IAC 144 in the natural processing.

Published: June 2019

Growing Coffea arabica in regions of the Western Amazon is limited by early maturation and by its limited adaptation to regions of low altitude and high temperature. The aim in this study was to quantify the genotype × environment interaction of C. arabica lines in four different environments of the Western Amazon, seeking to assist selection of new lines with greater adaptability and stability for the region. In the months of December 2012 and January 2013, four competitive trials were set up in municipalities of the states of Rondônia and Acre. Each trial was composed of 21 lines and 4 reference cultivars evaluated as controls recommended for planting in the southeast region. In combined analysis, significant differences were not detected between the cultivars and controls; the mean yield of hulled coffee was 12.05 bags ha-1. The Alta Floresta Do Oeste environment has higher yield and is the only environment favorable for growing C. arabica; that environment is differentiated from the others through its higher altitudes and low temperatures. Through GGE biplot analyses, lines 12 and 13, identified as H514-7-10-6-9 and H514-7-10-6-2-3-9, were found to have results superior to the controls in the municipality of Alta Floresta Do Oeste, RO. The gain from selection of 56% obtained from line G12 and the gain of 46% obtained from line G13 show performance superior to the best control. The germplasm studied does not have genetic variability that contributes to selection of plants for adaptation to the low altitude and high temperatures in the amazonic region.

Business School Teachers’ Experiences with a Student with Autism Spectrum Disorder
Authors: Vadnjal Jaka , Radoja Darinka
Published: June 2019

Autism has become an increasingly relevant topic in the research of neuroscience with the objective of enabling people with this condition to become equal opportunity members of the society; this includes an exploration of the benefits of the public education system. However, the science and knowledge in this field have thus far been limited, and the results of scientific findings have been very rare. The objective of the study was to explore primarily the first experiences of higher education teachers dealing with a student with an autism spectrum disorder. The aim was to learn lessons and contribute to some new understanding of special and adapted pedagogical approaches. The methodology of the study is qualitative, using (i) a case study as an objective of the researchers, and (ii) in-depth interviews with the twelve teachers about their experience with (for them) the new demanding assignment to teach a student with an autism spectrum disorder. The case study is about three years of undergraduate studies of a student with autism spectrum disorder who, in the end, obtained a bachelor’s degree in the field of business. The findings reveal that teachers generally viewed the experience as very positive and found teaching to be a challenge. For success, cooperation with experts and parents is crucial, but the education institution (of which all are stakeholders) could and should have done more. However, taking into account that the challenge is new, this study may contribute to some further development.
Advancing the Scholarship of Teaching and Learning using Learning Theories and Reflectivity
Authors: Shawa Lester Brian
Published: June 2019

The Scholarship of Teaching and Learning (SoTL) remains a mostly elusive notion. For universities to genuinely contribute to SoTL, they must delineate clear parameters of engagement. For example, while some engage SoTL at the academic level, others examine it from an institutional policy perspective. Others view it from national and international frameworks that impact teaching and learning in universities. Engaging SoTL at the academic level, this article uses a postgraduate diploma module, Higher Education Context and Policy (mostly attended by university academics from South African universities) to show how a facilitator could draw from learning theories and reflectivity to teach and advance SoTL. More specifically, it demonstrates how a facilitator could mediate the module utilising a social constructivist learning theory perspective.

Battery Drain Denial-of-Service Attacks and Defenses in the Internet of Things
Authors: Ioulianou Philokypros P. , Vassilakis Vassilios G. , Logothetis Michael D.
Published: June 2019

IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL) is a popular routing protocol used in wireless sensor networks and in the Internet of Things (IoT). RPL was standardized by the IETF in 2012 and has been designed for devices with limited resources and capabilities. Open-source RPL implementations are supported by popular IoT operating systems (OS), such as ContikiOS and TinyOS. In this work, we investigate the possibility of battery drain Denial-of-Service (DoS) attacks in the RPL implementation of ContikiOS. In particular, we use the popular Cooja simulator and implement two types of DoS attacks, particularly version number modiﬁcation and “Hello” ﬂooding. We demonstrate the impact of these attacks on the power consumption of IoT devices. Finally, we discuss potential defenses relying on distributed intrusion detection modules.
Autonomous Navigation Control of UAV Using Wireless Smart Meter Devices
Authors: Ueda Kiyoshi , Miyoshi Takumi
Published: June 2019

In preparation for the upcoming home delivery services that rely on Unmanned Aerial Vehicles (UAVs), we developed a new multi-hop radio network that is laid over a smart meter network transferring electric energy information only. In this network, a UAV follows, for navigation purposes, the topology of a virtual network overlaid on the physical smart meter network. We established a service management control method which does not rely on image analysis or map information processing, i.e. processes that consume precious power resources of the UAV. Instead, navigation is based on the routing technology. The current distance between the UAV and a node of the smart meter network is measured by means of the radio transmission loss value, therefore determining the position of the UAV. A two-layer network model has been proposed. One layer consists of a network of nodes in a residential area with scattered buildings – a location that is safer to navigate – while the other is an access network of nodes in a densely populated area. Then, we proposed methods to determine the direction of movement towards the next hop node on the data-link layer and the end node on the network layer, which is the target destination. We implemented a software-based test system and veriﬁed the eﬀectiveness of the proposed methods.

Published: June 2019

Ocimum tenuiflorum L., commonly known as ruku in Malaysia, is usually cultivated as a
garden ornamental plant because of its small purplish and some yellowish flower.
Additionally, the young leaves of O. tenuiflorum L. are used to make Nasi Ulam. In this
study, we investigated the nutritional values of O. tenuiflorum leaves and stems to find a
rich source of essential nutrients needed in daily diet. High pressure liquid
chromatography (HPLC) and gas chromatography/mass spectrophotometer (GC/MS)
methods were used to measure the amino acid and fatty acid content of leaves and stems
of O. tenuiflorum L. The result of antinutritional compositions of the leaves and stems
displayed as a safe range of compounds that were effective to increase absorption of
nutritional compound by body cells. The result of fatty acid profile showed that the
butanoic acid as the highest amount of fatty acid content in stems and leave compared to
other fatty acid compositions. The result of amino acids profile indicated that αaminobutyric acid and cysteine (non-essential amino acid) showed the highest and the
lowest amount of amino acid content in stem and leaves consequently. Vitamin E and C
showed the high and lowest amount of vitamins content in the leave and stem,
respectively. In conclusion, the result of antinutritional and nutritional contents of O.
tenuiflorum L. leaves and stems clearly indicated that the antinutritional compounds were
in the safe range. The amount and nutritional content of the leaves and stem proved that
this plant a good source to improve our body health system.

Published: June 2019

En este artículo de investigación se identifica las percepciones del grupo LGBTI frente a las creencias religiosas, estudio aplicado en la Facultad de Trabajo Social de la Universidad Laica Eloy Alfaro de Manabí, con el propósito de dar a conocer si las prácticas religiosas rechazan la homosexualidad, debido que las diferentes religiones como la Católica, Evangélica, Testigo de Jehová, entre otras,   de una u otra forma han excluido por muchos años a este colectivo, así mismo se expone las convicciones religiosas que habla acerca de la homosexualidad, lesbianismo, travestismo, entre otros. Es conocido que estas prácticas sexuales en épocas pasadas eran poco visibles ante la sociedad, pero a medida que ha pasado el tiempo y con la aprobación de la ley de los Derechos Humanos sobre los grupos LGBTEI, han provocado la reacción de grupos religiosos extremistas, generando distintas percepciones, lo que ha ocasionado la generación de violencia en la sociedad. Ante ello, el objetivo principal es identificar cuáles son los fundamentos que sustentan las creencias religiosas y su incidencia en la diversidad sexual en los estudiantes de la Facultad de Trabajo Social y para lograr la obtención de datos se opto por la aplicación de la encuesta. La información proporcionada con mayor realce fue que la gran parte de los encuestados expresaron que las prácticas religiosas no influyen directamente en la diversidad sexual, hasta expresaron estar de acuerdo con el matrimonio del mismo sexo, demostrando así que los estudiantes de la Facultad de Trabajo Social, no sienten que las creencias religiosas afectan la diversidad sexual.

Published: June 2019

El Bono de Desarrollo Humano en Ecuador, es parte de las transferencias monetarias condicionadas implementadas en América Latina desde el 2000. Se caracteriza por transferir dinero a familias en extrema pobreza, establecer condicionalidades y articularlas a otros servicios estatales. Inicia en 1998 en un contexto de crisis económica y política de ajuste, tiene reformas de cara a la política social vigente. La investigación mide la pobreza multidimensional de los hogares antes y después del Bono, e identifica las privaciones que a ella contribuyen. Las dimensiones se construyeron de manera participativa, designándose pesos diferenciados en función del sentir y percepción de sus participantes. Se aplicaron 255 encuestas por muestreo estratificado, en un universo de 1012 hogares; con ± 5%  de margen de error y 95% de nivel de confianza. La metodología aplicada, toma como base el método de Alkire y Foster; observa sin embargo los objetivos particulares del territorio, del programa y la vigencia de las políticas sociales.  Se identifican y afinan indicadores, se agrupan y ponderan en función de umbrales de privación, propios para el contexto local en 6 dimensiones: vivienda, servicios básicos, educación, trabajo/empleo, salud y organización.  Los resultados demuestran mejoras en sus condiciones de vida. El puntaje máximo de privaciones previo al bono es de 35,75 y el mínimo de 10,75; mientras que ahora es de 23,5 y 5 respectivamente. Los cuartiles establecidos clasifican a los hogares en: poco privado, privado, muy privado y extremadamente privado. La mayor cantidad de privaciones derivan a educación, servicios básicos y vivienda.  La deserción escolar por embarazo adolescente, el analfabetismo aún persiste; de ahí la necesidad de revisar y direccionar la política social.

Pemeriksaan model kapal terdiri dari pemeriksaan permukaan dan konstruksi lambung, dengan beberapa parameter pengukuran yang perlu diperhatikan: frame spacing 1 sampai dengan frame spacing 20 station, pemeriksaan point AP (After Perpendicular) ke bagian paling belakang dan pemeriksaan point FP (Fore Perpendicular) ke bagian paling depan model kapal. Pengukuran dilakukan dengan meletakkan model kapal diatas marking table untuk melakukan pengukuran dan pemeriksaan dimensi baik pada arah x, y maupun z. Alat waterpass digunakan untuk mengetahui pelurusan posisi model kapal. Setelah itu dilakukan penandaan frame station, waterline dan draft serta nomer lambung model uji kapal. Kualitas keakurasian pengukuran sangat ditentukan oleh alat ukur dan prosedur yang digunakan.Tinggi rendahnya tingkat ketelitian hasil suatu  pengukuran dapat dilihat dari harga deviasi hasil pengukuran

Authors: Murwatono Totok Triputrastyo
Published: June 2019

Keterbatasan kedalaman fasilitas pengujian model yang ada mengharuskan adanya rekayasa sehingga bisa dilakukan simulasi pada tangki uji, yaitu dengan melakukan optimasi desain sistem tambat yang ada menjadi seolah-olah lebih pendek ( perairan yang lebih dangkal ) sehingga bisa dilakukan simulasi model fisik. Filosofinya adalah bahwa sistem tambat ( mooring ) yang telah direncanakan diperpendek sesuai dengan yang diharapkan kemudian hasil simulasi numerik sistem tambat yang lebih pendek divalidasi dengan hasil simulasi numerik kondisi sistem tambat kedalaman penuh. Jenis tali tambat yang digunakan, besarnya pre-tension, sudut pre-tension, ukuran dan jenis kapal ( floater ) merupakan aspek yang memainkan peran utama. Validasi hasil simulasi meliputi validasi statis yaitu untuk mengetahui karakteristik statis dari material sistem tambat, kemudian validasi dinamis yaitu untuk mengetahui sifat dinamis dari material sistem tambat. Hasil prediksi yang dilakukan dengan simulasi numerik diterapkan pada set-up pengujian model hingga ditemukan model sistem tambat yang mempunyai sifat dinamis dan statis yang mendekati sistem tambat kedalaman penuh.

Authors: Aminuddin Jamrud
Published: June 2019

Gelombang laut merupakan salah satu sumber energi alternatif yang dapat digunakan sebagai pembangkit listrik. Pembangkit Listrik Tenaga Gelombang Laut (PLTGL) secara umum bekerja dengan mengkonversi energi gelombang laut menjadi energi mekanik, kemudian energi mekanik tersebut selanjutnya dikonversi menjadi energi listrik. Perhitungan energi gelombang laut membutuhkan persamaan yang mampu menghubungkan antara parameter gelombang laut yang diukur secara langsung dengan parameter energi rata-rata gelombang laut tersebut. Perumusan persamaan tersebut telah dilakukan dengan memanfaatkan konsep gelombang mekanis dimana energi total sebuah gelombang adalah penjumlahan linear antara energi kinetik dan energi potensial. Berdasarkan perumusan yang telah dilakukan diketahui bahwa parameter-parameter yang berpengaruh terhadap nilai rata-rata energi gelombang laut persatuan luas adalah massa jenis air laut, percepatan gravitasi, dan amplitudo gelombang laut. Selain itu, melalui perhitungan pada beberapa sampel data diketahui bahwa nilai energi rata-rata gelombang laut mendekati dua kali lipat ketinggian gelombang tersebut.

A review study on Corrosion Fatigue and its related testing methodologies
Authors: Abbasi Farshad
Published: June 2019

Corrosion Fatigue is the mechanical degradation of a material under the joint action of damage mechanisms corrosion and fatigue. Corrosive nature of the seawater puts severe durability requirements on materials of which are often exposed to corrosion fatigue and abrasive conditions simultaneously. Therefore, identification of the combined effects of both corrosion and fatigue damage mechanisms is necessary to improve predictive models for the corrosion fatigue phenomenon. Present article is the result of a desktop study (scientific literature and standards) with the aim of study the feasibility of designing and manufacturing of a corrosion fatigue testing set-up that would allow the designer to compare the performance of different materials exposed to corrosion fatigue, permitting also the comparison with results from dry fatigue testing. The corrosion fatigue mechanism is described in more detail and a short presentation of some typical lab-scale corrosion fatigue test setups is given. This is followed by illustration of international standards and guidelines which will be used to design a new corrosion fatigue test set-up for evaluating the fatigue behavior of material in seawater environment. Finally the experimental techniques for corrosion fatigue crack detection and propagation along with the fundamental basic of corrosion fatigue modeling are illustrated.

Framing immigrants as seekers of social benefits: the impact of the Great Recession at the family-level and the development of anti-immigrant anxieties
Authors: Fernández-Barutell Luis
Published: June 2019

Substantial research has addressed the association between economic factors (e.g., employment rate) and perception of immigrants among the general public in the host societies. This study used the Transatlantic Trends Survey 2014 to examine whether the characterization of immigrants as social benefits seekers is related to one´s family financial situation being greatly affected by the Great Recession. We conducted a series of ordinal logistic regressions to compare three different geopolitical contexts, namely the United States, the Southern Europe region, and the triad France-Germany-United Kingdom. Our results confirmed that framing immigrants as social benefits seekers is indeed related to one´s family being greatly impacted by the Great Recession. Significantly, the direction of such association varies among contexts, as those greatly impacted by the crisis in Southern Europe showed lower odds of framing immigrants as social benefits seekers, while the opposite happening in both the United States and the triad France-Germany-United Kingdom. Recommendations for practice and research are discussed.
