Resumo: A sociedade contemporânea vivencia a era da conexão, mobilidade e ubiquidade na comunicação humana, desencadeando novas formas de interação e colaboração em redes e ambientes on-line. Neste contexto, há uma disseminação crescente e acelerada do uso de aparelhos móveis, e inevitavelmente esse uso começa a ocorrer com mais frequência na escola. O objetivo desta pesquisa foi compreender os motivos e desdobramentos do uso dos aparelhos celulares pelos estudantes na escola. A metodologia utilizada foi a Teoria Fundamentada (Glaser; Strauss, 1999) e os dados foram obtidos por meio de interações no Twitter, questionário e entrevistas on-line com estudantes que estivessem acessando a internet na escola por meio de um aparelho móvel. Com base nos dados coletados, foram elaboradas quatro categorias explanatórias do uso do celular na escola por estudantes: regras, uso didático, motivação e consequências. A partir da análise dos dados, nota-se que, em geral, as escolas tendem a proibir o uso, contudo, os estudantes costumam transgredir, utilizando seus celulares em virtude do tempo livre na escola ou do tédio nas aulas. Além disso, relata-se o uso com a finalidade de acesso às redes sociais, de distração e de pesquisa de conteúdo relacionado às disciplinas. Neste cenário, indica-se que a escola compreenda as questões sociais e culturais relativas à cibercultura dos jovens e perceba o fenômeno como uma oportunidade de aproximação e aprendizagem mútua.

Matrix Metalloproteinase-7 Is a Urinary Biomarker and Pathogenic Mediator of Kidney Fibrosis

Published: September 2016

Matrix metalloproteinase-7 (MMP-7), a secreted zinc– and calcium–dependent endopeptidase, is a transcriptional target of canonical Wnt/β-catenin signaling. Because Wnt/β-catenin is activated in diseased kidney, we hypothesized that urinary MMP-7 level may be used as a noninvasive surrogate biomarker for fibrotic lesions. To test this hypothesis, we conducted a cross-sectional study, measuring urinary MMP-7 levels in a cohort of 102 patients with CKD. Compared with normal subjects, patients with various kidney disorders had markedly elevated urinary levels of MMP-7. Furthermore, urinary MMP-7 levels closely correlated with renal fibrosis scores in patients. In mice, knockout of MMP-7 ameliorated the fibrotic lesions and expression of matrix genes induced by obstructive injury. Genetic ablation of MMP-7 also preserved E-cadherin protein expression and substantially reduced the expression of total and dephosphorylated β-catenin and the de novo expression of vimentin and fibroblast-specific protein 1 in renal tubules of obstructed kidneys. In vitro, MMP-7 proteolytically degraded E-cadherin in proximal tubular cells, leading to β-catenin liberation and nuclear translocation and induction of β-catenin target genes by a mechanism independent of Wnt ligands. Finally, pharmacologic inhibition of MMP-7 immediately after obstructive injury reduced renal fibrosis in vivo. These results suggest that MMP-7 not only can serve as a noninvasive biomarker but also is an important pathogenic mediator of kidney fibrosis.

The Oxford Classification of IgA nephropathy does not account for glomerular crescents. However, studies that reported no independent predictive role of crescents on renal outcomes excluded individuals with severe renal insufficiency. In a large IgA nephropathy cohort pooled from four retrospective studies, we addressed crescents as a predictor of renal outcomes and determined whether the fraction of crescent-containing glomeruli associates with survival from either a ≥50% decline in eGFR or ESRD (combined event) adjusting for covariates used in the original Oxford study. The 3096 subjects studied had an initial mean±SD eGFR of 78±29 ml/min per 1.73 m2 and median (interquartile range) proteinuria of 1.2 (0.7–2.3) g/d, and 36% of subjects had cellular or fibrocellular crescents. Overall, crescents predicted a higher risk of a combined event, although this remained significant only in patients not receiving immunosuppression. Having crescents in at least one sixth or one fourth of glomeruli associated with a hazard ratio (95% confidence interval) for a combined event of 1.63 (1.10 to 2.43) or 2.29 (1.35 to 3.91), respectively, in all individuals. Furthermore, having crescents in at least one fourth of glomeruli independently associated with a combined event in patients receiving and not receiving immunosuppression. We propose adding the following crescent scores to the Oxford Classification: C0 (no crescents); C1 (crescents in less than one fourth of glomeruli), identifying patients at increased risk of poor outcome without immunosuppression; and C2 (crescents in over one fourth of glomeruli), identifying patients at even greater risk of progression, even with immunosuppression.
FACING 2020: THE 9 TRAITS OF SUCCESSFULL MIGRANT ENTREPRENEURS IN THE MUNICIPALITY OF ROME
Authors: Cillo Valentina , Caggiano Valeria
Published: September 2016

Abstract:The distinctiveness of migrants’ entrepreneurial propensity can be explained by considering both internal characteristics of the individual migrant, as well as the external environment of the host economy he/she operates in (Kloosterman et al. 1999). Migrants can perceive and seek entrepreneurial opportunities through specific sets of resources and personality-traits (Kloosterman/Rath 2001, Kloosterman 2010). Despite of this, the topic is vastly under-studied compared to its economic importance. After an in-depth study of the literature status quo about it, the paper analyses the motivation, intention, self-efficacy, culture, entrepreneurial orientation and performance of immigrant entrepreneurs. The main aim is to verify to what extent perceptions and skills of these immigrant entrepreneurs are similar to entrepreneurial psychological constructs studied in the literature. The used research instrument was the semi-structured interview consisting of 49 open-ended questions directed at the sample under examination. The results of the study showed a significant correlation between motivation and business performance (a motivated entrepreneur is more likely to succeed in business than an unmotivated entrepreneur) and a significant positive correlation between culture and motivation to start a business (a culture that is supportive of entrepreneurial activities, lowuncertainty avoidance, high individualism and lowpower distance relates positively to a high level of entrepreneurial self-efficacy).Keywords: Migrants, Entrepreneurs, Traits, Europe 2020

Abstract:Education is a complex phenomenon that needs to address the motivational dimension of students. The objective of the study is to discover and check, by the opinion of secondary school students, the motivation level (intrinsic, extrinsic) of Galician young, as well as determining which of the social and school variables affect significantly that motivation. For it, there was realized a quantitative and descriptive study, relating the variables of students and the educational center with the motivation measured by the CMEA (Section motivation) questionnaire. It was found that the Galician teenagers have more extrinsic motivation that intrinsic motivation, showing significant variations depending on the age, education, course and province variables. Also, confirmed by Scheffé the existence of solid reasons to support higher levels of motivation in younger teenagers who have good academic records, enrolled in the first years of compulsory secondary education and living in small towns. In conclusion, no doubt that motivation is a variable of great significance in personal and contextual fit in the adolescent population.Keywords: Intrinsic motivation, extrinsic motivation, teenagers, secondary education.Resumen:La educación es un fenómeno complejo que necesita atender la dimensión motivacional del alumnado.

Abstract:The multiple sclerosis affects 46000 people in Spain and is suffered by young adults mainly. Nevertheless, nowadays numerous cases are discovered in the adolescence. EM’s diagnosis in this stage influences all the dimensions of his development. To avoid this impact and to manage to favor the adolescence development positively, it´s necessary to encourage the subject´s personal characteristics that helps in the disease´s adaptation and gets a quality of life. For this reason we have believed necessarily to approach the above mentioned characteristics from the positive psychology, with the aim to get an improvement the mood to personal and clinical level, as well as an increase in the sensation of the psychological and physical well-being across the Fierabrás preventive program. We intervened through a case study with two subjects (separately), evaluating the efficiency of the program with three instruments: HAD Scale, Authentic Happiness Inventory and SF-36 Questionnaire. The results indicate that the program appear to be effective in the teenager with EM in the treatment of the depression and certain dimensions of the psychological well-being. Though for the healthy teenager it doesn´t appear to be effective in the treatment of the anxiety and depression, it favors diverse dimensions of the psychological well-being.Key Words: Adolescence, multiple sclerosis, positive psychology, quality of life.Resumen:La esclerosis múltiple afecta a 46000 personas en España y se da en mayor medida en adultos jóvenes. Sin embargo, en la actualidad se están descubriendo numerosos casos en la adolescencia. El diagnostico de EM en esta etapa afecta a todas las dimensiones de su desarrollo. Para evitar este impacto y lograr favorecer el desarrollo de la adolescencia de una manera ajustada, es necesario fomentar aquellas características personales del  sujeto que ayuden en la adaptación a la enfermedad y en la consecución de una calidad de vida óptima. Por este motivo hemos creído necesario abordar dichas características desde la psicología positiva, con el objetivo de obtener una mejora del estado de ánimo a nivel personal y a nivel clínico, así como un aumento en la sensación del bienestar psicológico y físico a través del Programa de Intervención Fierabrás. A través de un estudio de caso único se intervino sobre una muestra de dos sujetos (por separado), evaluando la eficacia del programa con tres instrumentos: la Escala HAD, el Inventario de la felicidad auténtica, y el Cuestionario SF-36.

Abstract:THE DIFFICULTY OF REACHING AGREEMENT ON HUMAN RELATIONSHIP: EGO CONTROL TO INNER PEACE.Wanting to be right is the main cause of conflicts involving human relationship. And the reason for the being of such cause is found in the ego. (We will use the term Ego, as part of the self that is at the service of the superego, in the sense Capra) It is assessing the psychological distress caused by the dependence of the ego. We believe that in the field of psychotherapy is of great importance to the domain of the ego to reach agreement among professionals that benefit our patients and not confuse them and learn to eliminate psychological suffering that produces lose control of the ego. To the above can be solved and lead a life of healthy relationship, outside prejudices and complexes have two fundamental tools; assertiveness and self-esteem.Keywords: assertiveness, self-esteem, ego, conflicts, complexes, and prejudices.Resumen:Querer tener razón es la principal causa de los conflictos que afectan a las relaciones interpersonales. Y la razón de ser de dicha causa la encontramos en el Ego. (Vamos a utilizar el término Ego, como la parte del Yo que se pone al servicio del superyo, en el sentido de Capra) Es de valorar el sufrimiento psicológico que provoca la dependencia de dicho ego. Consideramos que en el campo de la psicología, la psicoterapia es de gran importancia el dominio del ego para poder llegar a acuerdos entre los profesionales que beneficien a los sujetos, a los pacientes y no los confundan y de alguna forma se les pueda enseñar a eliminar el sufrimiento psicológico que produce el descontrol del mismo. Para que lo anterior se pueda solucionar y llevar una vida de relación interpersonal saludable, es decir fuera de prejuicios y conflictos, disponemos de dos herramientas fundamentales la asertividad y la autoestima.Palabras clave; asertividad, autoestima, ego, conflictos, complejos y prejuicios.

Abstract:LIFE STORIES OF OFFENDERS AND SOCIAL ADJUSTMENTThis is a qualitative study, with 20 male offenders, aged from 25 to 56 years old, incarcerated in a Portuguese prison. The objectives of this research were: to identify the beginning of anti-social conduct; the contextual factors that facilitate the occurrence of that conduct and the processes perceived by the offenders that would facilitate the social reinsertion. Methodology involves analysis of offender’s process and semi structured interview. Results indicate that 45% of offenders begin antisocial conduct in adolescence and 5% in childhood. The causes they appoint to deviant conduct were bad influence of deviant peers, drug addiction, and no employment. The factor they believe will help them in social reinsertion was to have a job. Data suggest certain reinsertion social strategies and the necessity of primary prevention of violence in schools.Keywords: anti-social conduct; offenders; social adjustmentResumo:Apresenta-se um estudo qualitativo, com 20 reclusos adultos do género masculino, com idades entre os 25 e os 56 anos, a cumprir pena numa prisão.

Published: September 2016

Nowadays the consumer society applies a huge amount of energy in many fields including the transportation sector. The application of the internal combustion vehicles contribute substantially to the air pollution. An alternative solution for reducing energy consumption is replacing the internal combustion vehicles by electrical or hybrid vehicles. Today one of the biggest disadvantages of the electrical vehicles is the finite capacity of batteries. The research topic presented in this paper is the „Energy Harvesting”, and development of energy recovery system for electrical vehicles which largely contributes in increasing the driving range. At the current phase of the research efficiency analysis of the heat energy recovery devices are investigated in real driving circumstances. Computer based mobile and wireless measurement system for the analysis was developed, tested and installed in a real vehicle. Driving tests were performed and analysed in different circumstances.

Nowadays a significant part of energy is consumed in buildings. In order to reduce the energy consumption different retrofit technologies are applied. As every building and every energy consumer is different the same modernization technic can not be used for all buildings. This paper shows a computer aided opportunity which is able to simulate different modernization technic for the same building in order to the best opportunity can be selected. The paper highlights the advantages of computeraided building design and the opportunities of optimization techniques in a new under design building case. This paper also contains examples in order to introduce this modelling method.
Time Domain Analysis and Spectral Methods for Determining Rotational Speed of Rotary Machines
Authors: Gárdonyi Gábor , Samu Krisztián
Published: September 2016

Accurate estimation of rotational speed of rotary machines has usually high priority in technical applications. This information should be calculated for many diagnostic algorithms, control or regulation processes. Incorrectly estimated values could occur serious disturbances in the operation of machines. Additional instrumentation often may be obstructed due to lack of space, but the construct of the machine may also affect the accuracy of measurement. In such cases, vibration diagnostic tools can be the disposal of difficulty. Mounting an acceleration sensor onto the outer surface of the measured device is not a major challenge. In most cases using time, frequency or quefrency domain analysis, it is possible to estimate the rotational speed of the analysed rotary machine. The calculated spectra and cepstra can help to determine the rotational speed more easily and more accurate than the time domain methods. This paper presents the comparison of these methods in terms of their usability and rotational speed estimation accuracy. A possible error of traditional optical measurement due to misalignment and benefits of the other methods are illustrated in this article via measured data series of a Brushless DC (BLDC) motor driven system.

Published: September 2016

Salah satu metode karakterisasi instrumen adalah uji in-situ, yang menempatkan instrumen dalam kondisi kerjanya untuk mengetahui pengaruh lingkungan terhadap kinerja kamera dan hasil pencitraannya. Uji in-situ kamera CCD ST-237A yang dilaksanakan pada tanggal 1, 2, dan 3 November 2004, berlokasi di Laboratorium Fisika Lanjut, UPI. Pada penelitian ini, kamera CCD ST-237A yang dilengkapi filter BVR Johnson terpasang pada Teleskop Celestron SC CGE-1100. Hasil analisa  uji in-situ terhadap kamera CCD ST-237A memberikan informasi kualitas kinerja yang sedikit berbeda dengan katalog. Hal ini dapat disebabkan karena chip kamera CCD bekerja pada lingkungan yang berbeda.

Authors: Kadarohman Asep
Published: September 2016

Minyak atsiri merupakan produk bahan alam dari keragaman hayati Indonesia yang berpotensi untuk dimanfaatkan sebagai bioaditif bahan bakar solar. Minyak cengkeh, minyak terpentin, minyak pala, minyak gandapura, minyak sereh dan minyak kayu putih adalah minyak atsiri yang potensial untuk dimanfaatkan sebagai bioaditif bahan bakar solar karena senyawa-senyawa penyusunnya memiliki rantai siklik dan ketersediaan oksigen yang cukup besar. Temuan penelitian ini dapat memberikan informasi mengenai minyak atsiri yang paling berpotensi untuk dijadikan sebagai bioaditif bahan bakar solar, yang selanjutnya dapat dilakukan kajian lebih lanjut tentang potensi minyak atsiri tersebut. Secara umum, penelitian ini dilakukan dalam tiga tahap. Tahap pertama karakterisasi minyak solar dan bioaditif menggunakan GC-MS, tahap kedua karakterisasi fisik solar-bioaditif pada berbagai komposisi, dan tahap ketiga penentuan laju konsumsi pada mesin satu silinder skala laboratorium. Hasil penelitian menunjukkan bahwa minyak cengkeh dapat menurunkan laju konsumsi bahan bakar sebesar 4,43% pada penambahan bioaditif 0,6%, minyak terpentin 5,07% pada penambahan bioaditif 10%, minyak pala 0,16% pada penambahan bioaditif 0,4% dan minyak kayu putih 1,82% pada penambahan bioaditif 3%, sedangkan  laju konsumsi bahan bakar yang ditambah minyak gandapura dan minyak sereh lebih tinggi dibandingkan solar murni. Dapat disimpulkan bahwa minyak cengkeh memiliki kemampuan paling tinggi dalam menurunkan tingkat laju konsumsi bahan bakar solar.Kata kunci: Minyak Atsiri, Solar, Bioaditif.

Parameter kualitas minyak bekatul ditentukan oleh banyaknya kandungan asam lemak tidak jenuh dalam minyak bekatul. Mengingat banyaknya manfaat asam lemak tidak jenuh dalam minyak bekatul, maka diperlukan cara yang baik dalam memperlakukan minyak bekatul agar kualitas asam lemak dalam minyak bekatul tetap baik. Pada umumnya proses pemanasan minyak dapat mengakibatkan kualitas minyak menjadi menurun karena dapat menyebabkan minyak mengalami oksidasi. Pada penelitian ini dilakukan uji stabilitas asam lemak tak jenuh minyak bekatul pada berbagai variasi suhu. Berdasarkan hasil penelitian ditunjukkan bahwa asam oleat, yang merupakan asam lemak tidak jenuh tunggal, memiliki stabilitas yang tinggi pada suhu 100oC, 120 oC, dan 160 oC. Stabilitas yang tinggi asam lemak tak jenuh pada fraksi tersabunkan bekatul ini memberikan potensi besar untuk menjadikan limbah padi (bekatul) sebagai food stuff, obat maupun minyak kesehatan untuk menurunkan kolesterol plasma darah yang berpotensi menyebabkan penyakit arterosklerosis.Kata kunci : Minyak Bekatul, Asam Lemak Tak Jenuh, Stabilitas Suhu.

We conducted a research about communication skill of secondary biology student in Arthropode classification using phenetic method. Data were obtained from written report and oral presentation. There were five indicators used to analyze communication skill in oral presentation, which included their ability to express opinion themselves and hearing the opinion from other, their ability to master the concept to be presented, their ability to communicate of results systematically and clearly, their ability to question, and their ability to answer. Five indicators used in written report were their ability to choose informative character to build fenogram, their ability to undergo step by step, resulted phenogram, their ability to interpret the results, and their ability to make a report. Results showed that communication skill in oral were good enough (63.75%), but low (56.25%) in written. Based on interview, however, students felt comfortable when teacher used the phenetic method to understand classification of Arthropode. This method has markedly stimulated the students to study actively in the classroom.Keywords: arthropode, communication skill, classification, phenetic method,
KAJIAN TERHADAP METODE DAN PENDEKATAN PEMBELAJARAN BIOLOGI DI SMA: KESENJANGAN DALAM PEMBELAJARAN DI KELAS (Study on teaching methods and teaching approaches in Biology Class of Senior High School: The gap in classroom teaching and learning)
Authors: Rahmat Adi
Published: September 2016

The study on teaching and learning of biology class of senior high school was aimed to identify teaching methods and teaching approaches used by teachers in their lesson plans and its implementation in the classroom. The study was conducted in nine senior high schools including three categories of school based on the passing grade of school entrance. Data was collected by documentation study, classroom observation, questioner and interview. Result showed that most of teachers planed their class with four teaching approaches and six teaching methods. The four teaching approaches were conceptual approach, process skill approach, inquiry, and environmental approach where as the six teaching methods were speech, discussion, question and answer, demonstration, experiment, and assignment. In the reality there was a gap between lesson plan and the teaching practice in the classroom. Although teacher planed their lesson using several teaching approaches the instructional systems delivered by teachers in the classroom were more conceptual and were conducted to give the students more subject matter. This type of teaching and learning was categorized by students as a common teaching and was disliked by some students. The comfort of the biology class sensing by student was due to the content of the subject matter which is very close to the human life rather than by the instructional systems delivered by teacher. Key words: teaching methods, teaching approaches, instructional system, biology class, senior high school
