Geopolymers (GP) were successfully synthesized from metabentonite (MB), metadiatomite (MD) and metakaolinite (MK). Characterization of their phase structure and microstructure was performed by XRD, FTIR, SEM/EDX methods. A SEM micrograph of GPMD shows a homogeneous surface with some longitudinal cavities in the gel, and it is significantly different from the micrographs of the other two geopolymer samples, GPMB and GPMK. A considerable amount of unreacted particles, as well as the presence of pores in the geopolymer matrix of GPMK and GPMD, indicate an incomplete reaction in the system. Aluminosilicate inorganic polymers, geopolymers, are quasi solid electrolytes which possess a high electrical conductivity at room temperature in relation to materials of similar chemical composition. The highest conductivity was found for the sample obtained from GPMK, amounting to 2.14 × 10–2 Ω–1cm–1at 700 ºC. The corresponding activation energies of conductivity for this sample amounted to 0.33 eV in the temperature range of 500–700 ºC. The geopolymer synthesized from metakaolin has good ionic conductivity values, which recommends it for use as an alternative material for an SOFC (Solid Oxide Fuel Cell).

Published: January 2020

Transmission infrared, Attenuated Total Reflectance (ATR) and Raman spectra of crystalline methylammonium iodide (MAI) and formamidinium iodide (FAI) in the temperature interval starting from –170 ºC to 200 ºC were studied. The spectra recorded in the region from 4000 to 500 cm–1 enabled resolving the ambiguities associated with the origin of some bands. For the first time a complete and detailed vibrational investigation and assignment of the IR spectra of these compounds based on the differences in the temperature dependent IR spectra for all phases, including the metastable ones, have been made. The findings support the already established crystal structure of the phases for both compounds. The correlation between the overtones and fundamental modes has been confirmed based on the temperature induced isosbestic point.

Abstract
Backgrand: The rate of reporting medication errors among nurses is lower than the actual rate. The role of education, encouragement, and promotion of reporting culture can contribute to the increase of errors reporting. This study was to investigate the effect of motivational system on reporting of medication errors in pediatric wards Methods: A quasi-experimental study was done through 60 nurses working in pediatric wards of the selected hospital were selected using census sampling method. Data were collected using a questionnaire based on eight medication principles completed by the nurses before and after the intervention. The intervention in this study was a motivational program with two parts of training and positive reinforcement that was conducted in 2018 for four months. For data analysis, SPSS16 was used. Results: After the intervention, the most prevalent medication error (60%) was in the principle of right medication (related to similar name. Furthermore, the mean score of nurses' medication error reporting increased significantly in all the principles after the intervention (P <0.05). Conclusions: Motivational system increased reporting of medication errors in nurses. Therefore, the managers can improve medication care and the children safety through continuous training and encouragement in the hospitals.
La letra como signo visual del arte: Análisis de sus funciones discursivas
Authors: Tostado Reyes Jose Antonio 
Published: January 2020

Esta investigación ha tenido como propósito examinar la relación paralela entre la producción plástica del texto en la obra artística y algunos procesos interpretativos implicados en su abordaje semiótico, a fin de esclarecer el impacto y las funciones del discurso escrito en las artes visuales. Se ha planteado una investigación de carácter descriptivo y documental, cuyos instrumentos de indagación fueron: 1) la investigación de perspectivas teóricas en torno a la semiótica del texto y 2) una selección y clasificación de piezas artísticas en las que el texto opera, semióticamente, de forma significativa. Se llevó a cabo un análisis de las obras seleccionadas a partir de la teoría de las funciones del lenguaje, propuesta por Roman Jakobson. La investigación ha permitido cruces teóricos que validan el análisis tipografístico como alternativa de estudio formal de las manifestaciones del arte. Y a su vez ha contribuido a una tipificación que trasciende las categorías históricas o estéticas tradicionales y permite abordar nuevas formas de apreciación y significación del texto (sea escrito, grabado, pintado, dibujado, impreso o tecleado) en relación con su materialidad y aporte expresivo al campo artístico.
Pese a la implicación directa entre arte y tipografismo, los materiales teóricos que documentan esa relación son escasos. Este trabajo ha permitido visibilizar las posibilidades expresivas del texto a partir de la identificación de sus funciones en la obra. La extrapolación del modelo jakobsiano —que parte de la oralidad y el discurso escrito tradicional— hacia el lenguaje plástico ha favorecido la comprensión de la complejidad discursiva en los dos niveles de la representación del texto en el arte: 1) su dimensión lingüística y 2) su carácter gráfico-expresivo; lo que ha permitido constituir una propuesta teórica que puede contrastarse con la producción artística.

Published: January 2020

Regression testing is very important but also a very costly and time-consuming activity that ensures the developers that changes in the application will not bring new errors. Retest all, selection of test cases and prioritization of test cases (TCP) approaches are used to enhance the efficiency and effectiveness in regression testing. While test case selection techniques decrease testing time and cost, it can exclude some critical test cases that can detect the faults. On the other hand, test case prioritization considers all test cases and execute them until resources are exhausted or all test cases are executed, while always focusing on the most important ones. Over the years, machine learning has found wide usage in solving different problems in software engineering. Software development and maintenance problems can be defined as learning problems and machine learning techniques have shown to be very effective in solving these problems. In the range of application of machine learning, machine learning techniques have also found usage in solving the test case prioritization problem. In this paper, we investigate the application of machine learning techniques in test case prioritization. We survey some of the most recent studies made in this field and provide information like techniques of machine learning used in TCP process, metrics used to measure the effectiveness of the proposed methods, data used to define the priority of test cases and some advantages or limitations of application of machine learning in TCP.

Published: January 2020

This paper uses Fractional-order PID control (FOPID) to control the speed of the DC motor. FOPID is more flexible and confident in controlling control higher-order systems compared to classical PID. In this work, the FOPID controller tuning is carried out using different methods ranging from classical techniques to most recent heuristic methods are Fractional Grey wolf Optimization and Nelder-Mead. Moreover, parameter estimation of real-world DC motor is carried out experimentally using Matlab/Simulink interfaced to an Arduino Uno board. The feasibility of FOPID is demonstrated through applications to well-known DC motor case study and the estimated DC motor. Based on ISE, ITE, and ISTE performance measures, the proposed approach provide less settling time, rise time and comparable overshoot compared with existing literature approaches. A robustness assessment with differences in the DC motor components is performed. Simulation finding provide validation of the suggested work and the FOPID controller effectiveness as compared to classical PID controller in terms of robustness and control effect.

Published: January 2020

This study aims to determine the determinants of intention in buying organic food. This thesis focuses on the consumer of organic food products in Indonesia who use online media in Instagram to make their organic food purchases with Theory of Planned Behavior. The data collection in this study was conducted in two stages, namely pre-survey to analyze opinion leaders and types of organic foods that will be used as a limitation of the study and the second stage is the research questionnaire. The analysis technique used is qualitative data analysis. Based on the results of the study conclusions can be drawn as follows: adherence to organic food and perceived behavioral control significantly influence buying intention in organic food, while subjective norms are found to have no significant effect on buying intention in organic food. Attitudes toward organic food have the strongest influence among the other two variables. Subjective norms have the lowest influence. Subjective norms or pressure from other people to consume organic food apparently do not have a significant effect because it does not originate from oneself (external) or is not their own volition, in contrast to the attitude and perceived behavior control variables that originate from oneself.

Authors: Murwati Murwati , Ferijani Agatha 
Published: January 2020

Strong personal traits such as reliable, discipline, devoted believer, high responsibility, willing to sacrifice, and put others needs above his/her own needs, are the personal traits that can build a prosperous society and a more developed country. It also can be said that the quality of someone is not merely measured from IQ (intelligence), but also from EQ (the growing traits). The real education must cover the formation of the whole humanity. The important component of an education institution is teachers. Thus, Yayasan Penyelenggaraan Ilahi Indonesia (YPII) with their vision and missions has formulated some traits (smart, authentic, faith to the Divine’s courtesy, and solider or COIS) that must be embraced by the teachers of YPII in order to be able to form good characters of the students thoroughly. This is the reason for evaluation of the implementation of the COIS values on the teachers of YPII. The research used qualitative approach using Focus Group Discussion (FGD) to gather data. Further evaluation on the implementation of the COIS values was to explore the factors supported or obstructed the implementation of COIS values. The research concluded that the implementation of COIS values in the teachers of YPII Semarang is not good. The reason is lack of continuous guidance and coaching. Teacher awareness on their role as a role model for students develops.

Published: January 2020

Abstract
Clustering as a fundamental unsupervised learning is considered an important method of data analysis, and K-means is demonstrably the most popular clustering algorithm. In this paper, we consider clustering on feature space to solve the low efficiency caused in the Big Data clustering by K-means. Different from the traditional methods, the algorithm guaranteed the consistency of the clustering accuracy before and after descending dimension, accelerated K-means when the clustering centeres and distance functions satisfy certain conditions, completely matched in the preprocessing step and clustering step, and improved the efficiency and accuracy. Experimental results have demonstrated the effectiveness of the proposed algorithm.

Abstract
Guillain–Barré syndrome (GBS) is an inflammatory disorder and an acute immune-mediated demyelinating neuropathy that causes reduced signal transmissions, progressive muscle weakness, and paralysis. The etiology of the syndrome still remains controversial and uncertain. GBS can be initiated and triggered by respiratory tract infections such as influenza, and intestinal infections such as Campylobacter jejuni. In addition, there is considerable evidence suggesting links between influenza vaccination and GBS. As reported previously, the incidence of GBS in individuals receiving swine flu vaccine was about one to two cases per million. Despite the influenza vaccine efficacy, its association with an immune-mediated demyelinating process can be challenging as millions of people get vaccinated every year. In this review we will discuss the association between influenza infection and vaccination with GBS by focusing on the possible immunopathological mechanisms.
Role of hepatokines in non-alcoholic fatty liver disease
Authors: Ke Yini , Xu Chengfu , Lin Jin , Li Youming 
Published: January 2020

Abstract
Non-alcoholic fatty liver disease (NAFLD) is closely associated with metabolic diseases like type 2 diabetes and obesity. In recent decades, accumulating evidence has revealed that the hepatokines, proteins mainly secreted by the liver, play important roles in the development of NAFLD by acting directly on the lipid and glucose metabolism. As a member of organokines, the hepatokines establish the communication between the liver and the adipose, muscular tissues. In this review, we summarize the current understanding of the hepatokines and how they modulate the pathogenesis of metabolic disorders especially NAFLD.

Abstract

Background and Objectives
Preoperative diagnosis of gastric glomus tumor is very difficult, and there are few reports regarding the endoscopic treatment of glomus tumor of the stomach. Our aim is to provide a retrospective assessment of the imaging features of endoscopic ultrasound (EUS) and treatment of choice of gastric glomus tumor.

Methods
A database of all patients with gastric glomus tumor who was treated at Shengjing Hospital of China Medical University between March 2011 and March 2017 was retrospectively analyzed. The EUS characteristics and patients’ clinical data as well as their treatment were reviewed. At the same time, we compared EUS characteristics of gastric glomus tumor with that of gastrointestinal stromal tumor (GISTs), leiomyomas, schwannomas, and ectopic pancreas.

Results
Eleven patients (3 male and 8 female patients) were included in the present study. The patients’ age ranged from 37 to 62 years (mean age, 50.1 years). Ten patients received EUS examination. Eight lesions were presented with mild-hyperechoic round or oval mass; one lesion was mild-hyperechoic oval mass with hypoechoic spots; one lesion was hypoechoic oval mass. One patient received endoscopic full-thickness resection; 3 patients were treated by endoscopic submucosal dissection; and laparoscopic resection was performed for 7 patients.

Conclusions
Gastric glomus has typical EUS features to differentiate from other submucosal tumors. Compared with surgery, endoscopic resection is also a safe and effective treatment of choice for gastric glomus tumor.

El enfoque intencional en las ciencias sociales: Una mirada estructuralista de las teorías científicas intencionales
Authors: Jaramillo Uribe Juan Manuel 
Published: January 2020

Frente a los distintos modelos de explicación en las ciencias (nomológico-deductivo, genético, teleológico, disposicional…) la explicación intencional tiene especial relevancia en las ciencias sociales y en la explicación/predicción del comportamiento de algunas entidades artefactuales. Dicha explicación permite diferenciar las ciencias sociales de las naturales. En este escrito se propone presentar, en el contexto de la concepción del estructuralismo metateórico, dicha explicación intencional y presentar algunos casos de su aplicación en teorías como la Teoría de elección racional, la teoría de juegos y la teoría de decisiones cuando tales teorías se aplican en las ciencias sociales, en especial, en economía.
