Authors: Curto-Rodríguez Ricardo
Published: March 2021

Iniciativas de Gobierno Abierto y de reutilización de la información del sector público están implementadas en la mayor parte de los países. Los portales de open data, repositorios digitales que centralizan la información en manos de las administraciones públicas bajo las premisas de formatos abiertos y licencias libres, son el destino de estos datos. En España el desarrollo de los portales de datos abiertos autonómicos es innegable, pasando de 11 portales operativos y una oferta aproximada de 5.000 datasets en el año 2013, a 17 repositorios y más de 14.000 conjuntos de datos en 2019. Este estudio se ocupa de valorar estos portales de datos abiertos autonómicos considerando cuatro dimensiones complementarias: número de datasets, aplicaciones elaboradas en base a esos conjuntos de datos, opciones de interacción disponibles y funcionalidad observada en el portal, encontrando importantes diferencias intracomunitarias.

Published: March 2021

This chapter is about a basic power-efficient object dropping game named “Catch Me If You Can,” which works on the Arduino platform. A dropping mechanism is developed using the servo motors interfaced to Arduino. The mechanism includes an object holder attached to the servomotor and a loading tube. The dropping of the objects is controlled by any wireless Bluetooth controlling device like a mobile phone or joystick and by the keypad interface installed in the design. The game is about catching the objects dropping randomly as a challenge which is controlled by the operator. The overall simulated design can be done in EasyEDA platform. The overall game can be controlled by an app which is designed by MIT App Inventor. This game can be implemented in Amusement parks, exhibitions, kid schools, and shopping malls. Besides this entertainment aspect, commercially it works as a small-scale product packaging system by involving DC motors, which are needed in moving packaging belts. This mechanism is efficient in packaging products in some specific count.
Customer-Operated Solar Photovoltaic System to Improve the System and Customer Reliability
Authors: Yadav Atul Kumar , Tak Lalit , Mahajan Vasundhara
Published: March 2021

In this chapter, the advantage of distributed generation can be seen in terms of system reliability and reliability of customer load. The solar photovoltaic (SPV) system is one of the distributed generations that may lead to the supply of electrical energy. The customer at the site of load demand mainly uses the SPV system. The installation of the SPV system is advantageous for the electrical load demand. Solar systems have greater efficiency for supplying both types of load (i.e., thermal and electrical) simultaneously. The modeling of two power system components (i.e., generation and distribution) can be performed using the Monte Carlo simulation (MCS) technique. The data used for generation modeling is taken from IEEE-RTS (reliability test system) and data for the distribution system is obtained from IEEE-RBTS (reliability busbar test system). The reliability parameters such as average energy not supplied (AENS) and loss of energy expectation (LOEE) are evaluated for the analysis of individual customer reliability and overall system reliability simultaneously.
Metaheuristic Techniques of Parameter Estimation of Solar PV Cell
Authors: Rawat Nikita , Thakur Padmanabh
Published: March 2021

The performance and efficiency of a solar PV cell are greatly dependent on the precise estimation of its current-voltage (I-V) characteristic. Usually, it is very difficult to estimate accurate I-V characteristics of solar PV due to the nonlinear relation between current and voltage. Metaheuristic optimization techniques, on the other hand, are very powerful tools to obtain solutions to complex non-linear problems. Hence, this chapter presents two metaheuristic algorithms, namely particle swarm optimization (PSO) and harmony search (HS), to estimate the single-diode model parameters. The feasibility of the metaheuristic algorithms is demonstrated for a solar cell and its extension to a photovoltaic solar module, and the results are compared with the numerical method, namely the Newton Raphson method (NRM), in terms of the solution accuracy, consistency, absolute maximum power error, and computation efficiency. The results show that the metaheuristic algorithms were indeed capable of obtaining higher quality solutions efficiently in the parameter estimation problem.

Authors: Wang Rebecca Jen-Hui , Chomiak Nicola A.
Published: March 2021

Robots and artificial intelligence have been touted as vehicles for generating operational efficiency and cost savings for a business enterprise. Specifically, automated, digitalized frontline services have the potential to streamline an enterprise's service efficiency, alleviate burdens from its human employees, and enhances its relationships with the customers. Besides these cost and functional benefits, this chapter posits that robotic services can garner customers' preferences and satisfaction, that is, there are situations in which robotic services are not only a cost-saving option, but they are even preferred by an enterprise's customers. Specifically, two important drivers—social distancing and utilitarian expectations of services—can lead to customers' choosing robots over humans. This chapter concludes that deploying and managing digital and automation technologies, such as service robots, in frontline services can not only transform an enterprise's operations but also enhance its customer management and service expectations.

Published: March 2021

Torrefaction process is the innovation to improve the properties of biomass. Residence time is one of the parameters that affects the properties of torrefied biomass. The residence time of a rotary kiln is the time of biomass drop into the cylinder until getting out of the cylinder. So, the propose of this study is the effect of lifters, inclination angle and rotational speed on the residence time of a rotary kiln for the torrefaction process. Palm kernel shell was used in this research. Palm kernel was chopped and minced to reduce size. The rotary kiln (0.3 meters diameter 6 meters in length) was used in this research. The number of lifters in this research were 0, 1 and 2. The rotational speed were 1, 2 and 3 rpm. The inclination angle was 1, 3 and 5 degrees. The hopper was used for the feeding system. The time was collected from biomass drop into the cylinder until getting out of the cylinder. The results reveal that the number of lifters, rotational speed and inclination angle affects the residence time of the rotary kiln. The residence time of rotary kiln was an increase when the number of lifters increase. The residence time of the rotary kiln was decreased when the rotational speed and inclination angle increase. It can be concluded that the least residence time of rotary kiln was 86.94 minute at 0 lifters, 3 rpm and 5 degrees. The most residence time was 9.22 minute at 2 lifters, 1 rpm and 1 degree.

Published: March 2021

This paper deals with numerical simulation and the geometrical analysis of an ocean Wave Energy Converter (WEC), which has as the operating principle the Oscillating Water Column (OWC). The goal was to evaluate the geometric shape influence of the OWC chamber in the hydropneumatic power available. Therefore, four geometric shapes were analyzed: i) Rectangle (RT), ii) Trapezium (TP), iii) Inverted Trapezium (TI) and iv) Double Trapezium (DT). For this, the OWC device was subject to a JONSWAP wave spectrum with peak period (TS) equal to 7.5 s and peak wave height (HS) equal to 1.5 m. To do so, Constructal Design was employed varying the Degree Of Freedom (DOF) H1/L (ratio between the height and length of the OWC chamber entrance). The problem constraints were the entrance area and the total area of the OWC chamber that were kept constant. For the numerical solution a Computational Fluid Dynamics (CFD) code, based on the Finite Volume Method (FVM),de0 was used. The multiphase Volume of Fluid (VOF) model was applied to tackle with the water-air interaction. The results indicated that when the Rectangle (RT) geometrical shape was employed an improvement of nearly 99% was achieved.

Objective:

The role of medical thoracoscopy in the treatment of pleural infections is increasingly being recognized. This study was done to assess the role of medical thoracoscopy in the management of carefully selected subset of patients with complicated parapneumonic effusions (PPEs).

Materials and Methods:

We analyzed retrospective data of 164 thoracoscopic procedures performed at our center on patients with complicated PPE in the past 10 years. Patients were subjected to medical thoracoscopy based on ultrasonographic stratification and a computed tomography (CT) thorax. Medical thoracoscopy was performed after an intercostal block under conscious sedation with midazolam (2 mg) and fentanyl (50 mcg) and local anesthesia with lignocaine 2% (10–15 ml), through a single port 10 mm diameter thoracoscope.

Results:

A total of 164 patients (119 males and 45 females) underwent medical thoracoscopy during the study period. The mean age was 47.4 ± 15.9 (median, 50; range, 16–86). The final diagnosis by thoracoscopy was bacterial empyema in 93 patients and tuberculosis in 71 patients. Medical thoracoscopy was successful without subsequent intervention in 160 (97.5%) patients, two patients underwent a second procedure, in the form of decortication, and two patients died due to sepsis. There were no major procedure-related complications that required intervention.

Conclusion:

Early adhesiolysis and drainage of fluid using medical thoracoscopy should be considered in patients with multiloculated complicated PPE after careful radiological (ultrasonography and CT) stratification, as a more cost-effective and safe method of management.

Authors: Ekanga Tresor
Published: March 2021

Доказано, что в одномерной многочастичной модели Андерсона со слабым взаимодействием в непрерывном конфигурационном пространстве имеет место спектральная и сильная динамическая локализация. Для получения этих результатов требуется, чтобы амплитуда взаимодействия была достаточно мала. Общая методика опирается на оценки, полученные в рамках многомасштабного анализа. Фактически показано, что оценки многомасштабного анализа для одночастичной модели остаются неизменными при переходе к многочастичным системам при условии, что межчастичное взаимодействие достаточно мало. Единственное условие, которое налагается на функцию распределения внешнего потенциала, представляющего собой случайное поле независимых одинаково распределенных случайных величин, состоит в том, что она должна быть логарифмически непрерывна по Гeльдеру.

Background: Total knee arthroplasty (TKA) is the most common surgical option for end-stage knee OA with knee deformity and persistent pain. This procedure has already been increased in national insurance era. There are many conditions may affect the outcome of TKA include: the complexity or difficulty of the surgery or specific states of the affected limb. The difficult conditions in primary TKA are extra-articular deformity, severe coronal deformity, stiffness knee, neglected dislocation or patella subluxation, post-osteotomy (HTO or DFO), previous incision surgery. The paper aims to review the conditions which may adversely affect the usually excellent outcome of TKA.Methods: This is a descriptive study. The study describes the difficult or complex situation in primary TKA. The data for this study was obtained from the 9 Government Hospital in Indonesia. The patients receive surgery between January and December 2019.Results: Totally, there were 881 patients receive TKA in 9 government hospitals in Indonesia during 2019. From those, there were 221 difficult TKA cases 31,38%, and 600 were the simple case (68,11%). Severe coronal deformity are 183 cases. TKA with the stiff knee are 52 cases. Cases with wound problems or previous incision are 12 cases. Ekstra articular deformity are 15 cases. TKA post osteotomy are 9 cases. TKA with genu recurvatum are 6 case. TKA with patella dislocation or subluxation is 4 case.Conclusions: Almost one-third of primary TKA are difficult cases that need much more advanced technique and advance implant (more expensive) for more extended durability (avoid failure and costly-revision). National insurance coverage should recognize primary-difficult TKA.

Published: March 2021

Background:Despite the high succesful rate of Total Knee Replacement (TKR), there are still patients with permanent dysfunction and a longer period of rehabilitation that interfere with functional performance. Strengthening exercise before TKR namely prehabilitation exercise using resistance bands is expected to optimize patient’s condition before surgery that will increase functional performance after TKR and accelerate rehabilitation programs.Methods:16 eligible patients were allocated into the treatment group (n=8) and the control group (n=8). The treatment group received 4 weeks of prehabilitation exercise with a frequency of 2 times and one time as a home program. The control group only received conventional therapy. The TUG and WOMAC scores were measured 3 times; at baseline, after 4 weeks of prehabilitation exercise and at 8 weeks of rehabilitation after TKR.Results:Before intervention, there were no significant differences between groups for the TUG score (p=0.674) and WOMAC (p=0.928). After 4 weeks of intervention, there was significant difference in the TUG score (p=0.003) and WOMAC (p=0.002), whereas at 8 weeks after rehabilitation programs there was a significant difference in the TUG score (p=0.009) while for the WOMAC score there was no significant difference (p=0.125).Conclusion:Prehabilitation exercise using resistance band improved functional performances in patients undergone TKR.

A Qualitative Description Investigation of U.S. Higher Education Quantitative Datasets
Authors: Ocean Mia , Hicks Karon
Published: March 2021

Currently, the U.S. system of higher education is almost exclusively evaluated by quantitative data based on traditional student trajectories and university structured programs. This could be problematic for community colleges and post-traditional students, who are a growing population at all institutions. Therefore, we conducted a pilot, qualitative description analysis of three U.S. quantitative national datasets to assess their accuracy and identify factors that influence classifications. We interviewed individuals (n=13) who would qualitatively be considered success stories, specifically individuals who attended community colleges during their undergraduate studies and ultimately high ranking graduate programs, to gather information about their educational timelines. In some cases, the datasets would classify these individuals as completers but not always. Participants would be classified as non-completers for two major reasons: transfer prior to Associate degree completion and limitations with prescribed timelines. The latter is complicated by the perceived freedom of the open door policy at community colleges. The results from this study indicate a need to modify existing quantitative metrics to purposefully incorporate community colleges and their students, and the findings reinforce the importance of qualitative research in higher education.

Authors: De Sá Jeferson Silva , Moreira Attus Pereira
Published: March 2021

A falta de técnicos habilitados, disponíveis no mercado de trabalho, para as atividades de georreferenciamento e certificação de imóveis rurais, exige uma intervenção urgente das universidades, responsáveis pela formação, desta modalidade de conhecimento.

O projeto tem como objetivo verificar, em cinco repetições sucessivas, a diferença linear e precisão na obtenção das coordenadas (E,N), UTM SIRGAS/2000, para um ponto fixo, implantado no Campus da URI - Santiago. Para os cálculos das coordenadas obtidas pelo processo do posicionamento por Ponto Preciso (PPP), foram utilizadas, como estação base fixa, durante os cinco processos de rastreio, os dados do rastreio do marco da URI Campus Santiago e da Base de Alegrete, RS, obtidos via Internet. Para o marco de Santiago, na tomada de dados, empregou-se receptor GNSS fixo, de dupla frequência e, para a base de Alegrete, foram utilizados os dados captados via Internet, no formato de arquivo RINEX, conforme disponibilizado para todas as estações bases da rede geodésica brasileira. Foram executadas cinco seções de observações geodésicas, com o emprego de um receptor GNSS, Leica Viva GS15.  Durante as leituras, o receptor base permaneceu instalado sobre o marco geodésico da Campus da URI Santiago, em modo estático e a antena receptora procedeu o rastreio do marco de apoio, no mesmo modo de rastreio.

As coordenadas geográficas obtidas pelos dois processos de rastreio serão transformadas em coordenadas geodésicas UTM SIRGAS/2000, bem como serão calculadas as diferença linear entre elas e analisados os comportamentos destas diferenças. Por fim, serão comparadas as médias das diferenças, caso haja, em cada método proposto.

Organizational difficulties in attracting talent should alert to the need of employer brands to present characteristics differentiating them from competitors. Employer branding is a fusion area between human resources and marketing, which aims to build an organization’s reputation as a great place to work. The future of organizations depends on the quality of the workforce they can attract (Chhabra & Sharma, 2014) and people, as brands, are the most important assets in a company (Backhaus & Tikoo, 2004). This research aimed to conceive and test a talent attraction model of graduated engineers for a large business group with decades of experience in industry and automotive sectors, in Portugal. Action research was performed in two cycles, consisting in focus group, intervention (detailed organizational presentation) and a final survey with 6 questions about organizational attractiveness of the organization in study. The Employer Attractiveness Scale by Berthon, Ewing and Hah (2005) was used as a guiding paradigm. Twenty recent graduates and finalists participated, with an average age of 23, male, from Mechanical, Automotive Mechanical and Industrial Management Engineering degrees of two Oporto Schools (Portugal). Data was collected personally, by researchers on campus. NVivo Content analysis and descriptive statistics were used, and intervention improvements were introduced before the second cycle. Results showed that: (i) The most valued dimensions by participants were development and economic; (ii) Before the intervention, students didn’t know the organization well, neither in terms of business areas or size; (iii) Post-intervention, participant’s opinion about the organization improved, with an average of 6.4 (1-7 lickert scale); (iv) After the intervention 90% would consider the organization as their employer. Based on the two cycles and organizational information, a model for engineer attraction was proposed, however, it’s overall principles might be adapted and applied to other areas of talent and different organizations facing similar challenges.

Este artigo refere-se a um recorte da dissertação de Mestrado “A História da Matemática: a Interdisciplinaridade e Lúdico-Pedagógico na Aprendizagem de Matemática”, defendida no Programa PPGECM da UEPB no ano de 2019. Nosso objetivo foi  analisar como o uso de atividades  de natureza interdisciplinar e lúdico-pedagógicas, a partir da História da Matemática pode contribuir para a melhoria da aprendizagem em Matemática. A pesquisa realizada foi de abordagem qualitativa cujo foco é o indivíduo com toda sua complexidade e na sua inserção  com o ambiente sociocultural. Para o seu desenvolvimento utilizamos como instrumento de análise: entrevistas, questionários e filmagens. A prática da Interdisciplinaridade e da História da Matemática começa a surgir ainda que timidamente em sala de aula e que a utilização de lendas de caráter histórico, associados ao lúdico puderam promover uma maior Motivação na aprendizagem da Matemática, colaborando na superação de uma visão eurocentrista dessa ciência.

Results of preliminary observations at SMPIF Al-Fikri Depok shows that KKM – Kriteria Ketuntasan Minimum (Minimum Mastery Criterion/students' learning achievement) 72 in Islamic Education subject was low because of the students’ embarrassment to ask questions, not paying attention to lessons and the lack of learning methods used by teachers. One of the factors causing it was that the learning methods used by teachers were less varied so that learning activities were monotonous. The purpose of this research is to find out the effect of applying the Examples Non Examples method in learning PAI. The method used is classroom action research (PTK). The object in this study were 42 students of grade VII. Data was collected by distributing learning achievement questionnaires to each student, and filling out observation sheets. The data was analyzed using quantitative calculations which later translated into presentations. Based on the results of students’ achievements after learning using the Examples Non Examples method, student achievement  increases each cycle. The results of the questionnaires  in the first cycle was 72.32% and in the second cycle was 83.68%, thus it can be concluded that the application of the Examples Non Examples method has increased students’ learning achievement by 11.11%.

Purpose: This article aims to evaluate the effect of dietary protein levels on growth performance and some blood biochemical composition of male Japanese quail.

Study Design: Qualitative Descriptive Design.

Subjects and Methods: Three hundred, three week old apparently healthy male Japanese quail were used in this experiment. The birds were randomly allocated into 5 groups with 3 replicates of 20 birds for 21 days of experimental period and placed in cages, measuring 100 cm (length) x100 cm (width) x 80 cm (height). Group A was fed on diet 1 containing 18% crude protein, Group B was fed on diet 2 containing 20% crude protein, Group C was fed on diet 3 containing 22% crude protein, Group D was fed on diet 4 containing 24% crude protein and Group E was fed on diet 5containing 26% crude protein. All groups were subjected to similar management practices.

Results: The findings showed that growth performance parameters significantly improved as dietary crude protein level increased. However dietary protein level beyond 22% has no beneficial effect on growth. Biochemical examination results demonstrated that the crude protein level in diet was not significantly affected the blood glucose, cholesterol,   bilirubin, calcium, phosphorus and liver enzyme activities (ASAT and ALT). However, we noticed a significant effect (P<0.05) about Total protein, Albumin, Urea, Triglycerides, Creatinine and Uric acid. Despite the variation of these parameters, they remain within the normal range.

Conclusion: Therefore, it is concluded that dietary protein levels do not affect quail health. The crude protein requirement for Japanese quail from 21 to 42 days old is 22%.

The purpose of this paper is to examine differences in factors affecting the probability of online and in-store purchase of telecommunications equipment in the Republic of Croatia. Online questionnaire survey conducted in September 2019 gathered responses that identified respondents’: method of telecommunications services and equipment purchase, their information gathering tools, factors affecting respondents’ telecommunications services and equipment purchasing decisions in general, and online and in-store purchasing decisions. 125 gathered responses were analysed using a binomial logistic regression. The results state that general factors incite respondents to purchase telecommunications equipment and services instore. Factors inciting online purchases are enabling factors and cause respondents to purchase telecommunications services and equipment online. Responses were further divided into subsamples depending on gender and education level. Results are consistent in tested subsamples. In the sample of male respondents, the results are consistent, while the female subsample shows does not exhibit statistically significant results. Furthermore, subsamples that allowed education level differences showed the results are supported for the subsample of respondents with higher education, and are not supported for respondents with secondary education.
Philosophia facta est quae philologia fuit

Friedrich Nietzsche se consagró activamente a la filología clásica —como alumno, estudiante, investigador y docente— por veintiún años; desde su entrada al célebre liceo clásico de Pforta (1858) hasta la renuncia a su cargo en la Universidad de Basilea (1879). Estos años constituyen casi la mitad de su vida consciente.1 Su retiro del puesto de profesor universitario no conllevó su renuncia a la filología como instrumento de interpretación del mundo, tanto de aquel de la antigüedad como el de la modernidad. La filología clásica fue la única disciplina científica en la cual Nietzsche se educó en forma sistemática y, como opción de vida, afectó su perspectiva, de intelectual y escritor, hasta el fin de su actividad efectiva. En El ocaso de los ídolos (Götzen-Dämmerung), obra de 1888, último año antes de su colapso mental, Nietzsche optó por dedicar el último capítulo a su adeudo para con los antiguos: “Lo que debo a los antiguos” (Was ich den Alten verdanke).
