Authors: Vlădescu Irina 
Published: December 2020

The last 29 years of education in the democratic system in Romania have shown that the use of mastery learning strategies is not present in our nowadays teaching-learning process. Even though studies were carried out to show the effectiveness of these strategies teachers still feel reluctant whether to implement a mastery learning model or not. The subject emphasized in this paper is related to the implementation of a mastery learning strategy during the teaching of English as a second language in a public school in Bucharest, Romania.

BACKGROUND: AQP proteins show a variety of functions in human cell metabolism. The role of different AQP subtypes in tumor metabolism and prognosis are subject of ongoing research. OBJECTIVE: To investigate the mRNA expression of Aquaporin (AQP) 3, 4, 7 and 9 in pT1 non-muscle-invasive bladder cancer (NMIBC) and its prognostic value in therapeutic decision making. METHODS: Formalin-fixed-paraffin-embedded (FFPE) tissues from transurethral resection of the bladder (TURB) from 112 patients with initial diagnosis of stage pT1 NMIBC were analyzed retrospectively together with clinical data and therapeutic approaches. mRNA expression of AQP3, 4, 7 and 9 was measured and quantified using RT-qPCR. RESULTS: Of the 112 patients (83.9%male, median age 72 years), 40 had a recurrence (35.7%), 16 a progression (14.3%) and 14 patients (12.5%) died tumor-related. mRNA expression for AQP3 was detected in 99.1%, AQP4 in 46.4%, AQP7 in 86.6%and AQP9 in 97.3%. Spearman analysis revealed statistically significant correlations between AQP3, AQP7 and AQP9 mRNA expression with adverse clinical and histopathological parameters (WHO1973 grade 3, concomitant Cis or multifocality). High AQP9 mRNA expression was associated with worse PFS in the total cohort ( p = 0.034) and in Grade 3 tumors ( p = 0.003) in Kaplan-Meier analysis. In patients with bladder sparing approach, high AQP3 mRNA expression was significantly associated with worse CSS in patients receiving BCG therapy ( p = 0.029). CONCLUSIONS: mRNA expression of AQP3, 7 and 9 correlates with adverse clinical and pathological parameters. AQP3 and 9 may help to identify a subgroup of highest risk patients who may be considered for early cystectomy.

Background: Brevican and neurocan are central nervous system-specific extracellular matrix proteoglycans. They are degraded by extracellular enzymes, such as metalloproteinases. However, their degradation profile is largely unexplored in cerebrospinal fluid (CSF). Objective: The study aim was to quantify proteolytic peptides derived from brevican and neurocan in human CSF of patients with Alzheimer’s disease (AD) and vascular dementia (VaD) compared with controls. Methods: The first cohort consisted of 75 individuals including 25 patients with AD, 7 with mild cognitive impairment (MCI) diagnosed with AD upon follow-up, 10 patients with VaD or MCI diagnosed with VaD upon follow-up, and 33 healthy controls and cognitively stable MCI patients. In the second cohort, 31 individuals were included (5 AD patients, 14 VaD patients and 12 healthy controls). Twenty proteolytic peptides derived from brevican (n = 9) and neurocan (n = 11) were quantified using high-resolution parallel reaction monitoring mass spectrometry. Results: In the first cohort, the majority of CSF concentrations of brevican and neurocan peptides were significantly decreased inVaDas compared withADpatients (AUC = 0.83.0.93, p≤0.05) and as compared with the control group (AUC = 0.79.0.87, p ≤ 0.05). In the second cohort, CSF concentrations of two brevican peptides (B87, B156) were significantly decreased in VaD compared with AD (AUC = 0.86.0.91, p ≤ 0.05) and to controls (AUC = 0.80.0.82, p ≤ 0.05), while other brevican and neurocan peptides showed a clear trend to be decreased in VaD compared with AD (AUC = 0.64.80, p > 0.05). No peptides differed between AD and controls. Conclusion: Brevican and neurocan peptides are potential diagnostic biomarkers for VaD, with ability to separate VaD from AD.

Published: December 2020

A k-Zumkeller labeling for the graph G = (V, E) is an assignment f of a label to each vertices of G such that each edge uv ∈ E is assigned the label f (u) f (v), the resulting edge labels are k distinct Zumkeller numbers. In this paper, we prove that the graph Pm × Pn is k-Zumkeller graph for m, n ≥ 3 while Pm × Cn and Cm × Cn are k-Zumkeller graphs for n ≡ 4 (mod2). Also we show that the graphs Pm ⊗ Pn and Pm ⊗ Cn for m, n ≥ 3 admit k-Zumkeller labeling. Further, the graph Cm ⊗ Cn where m or n is even admit a k-Zumkeller labeling.

Published: December 2020

The composite structures in the aerospace industry for in recent decades are widely applied however, at the beginning of the 21st century composites are growing rapidly. The largest companies in the aerospace industry are increasing the volume of composites application of in the structures, and nowadays the volume of composites reaches 50%. The different elements of aircraft and even highly loaded structures such as spars, ribs, skin, etc., are currently made from composites. First of all, this is due to the possibility of a significant reduction in the weight of the structure, as well as a decreasing in production costs. The advanced technologies in the engineering software allows to solute different complex problems. One of the main direct of research in the composites is optimization of composite structure due to improving the relative strength and relative stiffness of the composite structure, and improving the efficiency of manufacturing processes. There are a lot of methods of optimizations but currently the topological optimization is the most conceptual and forward-looking method. The main goal of the article is to analyze and estimate the approach for designing wing rib with symmetric laminated plates with the different fiber orientation based on the topology optimization. The following tasks were solved for this: firstly, a topological optimization model was determined. This model was based on maximum stiffness with a specified volume constraint is established. The next step was optimization by the solid isotropic material with penalization (SIMP) model and sensitivity filtering technique; as a result of optimization the topological structures of wing rib with different fibre orientations were obtained. The topological structure and stiffness of the wing rib depend on the fibre orientation. Finally, the corresponding morphing analysis of wing rib with laminated plates is implemented by adopting ANSYS, which verified the anti-deforming capability of topology structure and illustrated the feasibility for designing the wing rib. The result shows that the maximum deformation of optimized structure is 1.57mm, whereas the maximum deformation of the un-optimized structure is 2.02 mm. Under the condition of the same material removals, the optimized structure can decrease by more than 20% deformations.

The task to optimize the life cycle of new technique (aerospace, engineering products, etc.) in difficult economic conditions is stated and solved. The aim of the study is to develop a method to reduce the life cycle of complex technique creation. The subject of the research is the planning and management of the life cycle of complex technique in a highly competitive environment and stochastic behavior of high-tech products market. The paper shows the contradictions between the planned nature of modern production, which operates in conditions of Industry 4.0 and the stochastic behavior of the market. This contradiction leads to the relevance of short-term production plans with minimal risks. Therefore, the planning of the production system is carried out based on the portfolio that can be done in the short term. When planning new orders, it is necessary to shorten the life cycle of new equipment creation by analyzing the main stages: design, preparation of production, production. The optimization model to select the measures (project actions) at the initial stage of the life cycle is proposed. In order to generate the set from which the alternative options for activities are selected, expert assessments being ordered on the basis of the importance of time indicators, competitiveness, innovation, costs and risks are used. Simulation of the shortening of the new technique creation life cycle at a time of capacity constraints of production that creates high-tech products is carried out. The following mathematical models and methods are used: system analysis, optimization using integer programming, multi-criteria optimization, expert assessments, simulation modeling, agent-based modeling, risk assessment. The method allows to create competitive products at a time of capacity constraints by means of planning to shorten the life cycle of new technique creation and resources management.

The subject of this study is the radio frequency cyber vulnerability of information and control interaction technology in the wireless smart systems (WSS). WSS is the cyber-physical systems, that operate within the OSI model. The specificity and specialization of these systems are determined by radio technologies of the physical layer. For example, the Internet of Things (IoT, including medical IoMT), the Internet of Drones (IoD), systems for aviation monitoring ADS-B and traffic management ATM, and, in the future, the Internet of Everything (IoE) - all are types of WSS. The aim is to analyze the radio frequency parameters of information and control interaction in the WSS to identify possible radio frequency cyber vulnerabilities in the WSS. Objectives: summarize and systematize the physical and functional parameters of wireless technologies in the ISM (Industrial Scientific & Medical Band) and SRD (Short range devices) ranges, which are significant from the WSS radiofrequency cyber vulnerability perspective, including navigation technologies; analyze trends and methods of successful cyber attacks on the WSS; carry out expert assessments of potential WSSs cyber vulnerabilities depending on their architecture and application area. The methods used: analysis of trends in known radiofrequency incidents and expert assessments of the cyber vulnerability of the WSS information and control interaction channels. The following results were obtained: 12 actual WSS radio technologies were analyzed. 6 types of possible radio frequency cyber attacks on the WSS were typified. The expert assessment of the probability of exploiting vulnerabilities by ranges, radio technologies, and attack type was made. The special danger of high-tech targeted APT attacks, as well as the high potential radio vulnerability of cyber-physical systems, was shown. The cyber vulnerability of ADS-B aircraft systems was especially noted. Conclusions. The scientific novelty of the results obtained is as follows: a trend of APT attacks cost reduction and an increase in the probability of their implementation through the new capabilities of SDR technology (Software Defined Radio) were revealed. The possibility of a controlled SDR compromising of the security parameters of WSS channels in any radio range was shown. A promising direction of research was proposed - SDR-penetration testing of WSS.

Vivienda vernácula de las provincias de Cusco
Authors: Vargas Febres Carlos Guillermo 
Published: December 2020

La vivienda vernácula es la representación de la tradición, cultura y propia tecnología desarrollada por sus habitantes, respetando su entorno físico y cultural, así como el empleo de materiales de la zona y técnicas ancestrales. Este tipo de arquitectura es poco estudiada y mucho menos documentada. En el caso cusqueño, que posee muchas muestras de esta tipología tradicional, necesita ser expuesta y analizada; por lo que el objetivo del presente estudio radicó en la exploración y análisis arquitectónico de dichas edificaciones. La metodología aplicada respondió al método de investigación general de las ciencias sociales, apoyándose en la exploración; cada expresión arquitectónica analizada presenta particularidades individuales y coincidencias entre ellas. Las edificaciones analizadas mostraron diferencias sustanciales en los materiales y técnicas constructivas utilizadas, respondiendo a procesos culturales y materiales de su entorno; sin embargo, también presentan coincidencias en aspectos de distribución formal, poseyendo espacios centrales que no solo cumplen con la función de distribución de ambientes, sino que se convierten en los espacios fundamentales de la edificación, donde se desarrollan las actividades sociales, laborales y alimenticias.
Mihin oppilaita ohjataan?

Published: December 2020

Opinto- ja uraohjaus on noussut poliittiselle agendalle sekä OECD:n kaltaisten ylikansallisten toimijoiden piirissä että suomalaisissa koulutus- ja työvoimapoliittisissa keskusteluissa. Ohjauksen tarvetta on yleisesti perusteltu koulutuksellisten ja työvoiman kohtaantoa ja nuorten sosiaalistumista koskevien ongelmien lukuisuudella. Artikkelissa analysoidaan opinto-ohjaukselle asetettujen sisältöjen ja tavoitteiden perusteluja peruskoulun opetussuunnitelmateksteissä Suomessa. Aineistona toimivat kaikki peruskoulussa käytössä olleet opetussuunnitelman perusteet (5 kpl vuosilta 1970–2014). Lähestymistapamme painottaa kontekstin (peruskoulu) ja ajallisuuden (suomalaisen koulutus- ja yhteiskuntapolitiikan periodisointi) merkitystä.
Tarkastelemme peruskoulun opinto-ohjausta hallintana, joka perustuu tietyille moraalisille ja ideologisille perusteille, rationaliteeteille. Analyysimme tulokset osoittavat, että ylikansalliset tietoyhteiskunnan, elinikäisen oppimisen ja tasa-arvon diskurssit ovat asettaneet oikeutuksen peruskoulussa annettavalle opinto-ohjaukselle sekä muokanneet sen tavoitteiden ja sisältöjen perusteluja koko tarkastelemamme ajan. Analyysimme kuvaa miten Suomessa 1970–1980 -luvuilla muotoutuneet opinto-ohjauksen rationaliteetit ovat saaneet uudenlaisia painotuksia 1990-luvulta alkaen.

Published: December 2020

O presente artigo traz os resultados de uma pesquisa realizada no âmbito de um trabalho de conclusão de um curso de Licenciatura em Matemática, cujo objetivo geral foi investigar como se dá ainfluência da utilização do material manipulável na aprendizagem do conceito de radiano. Foi elaborada uma proposta didática com ênfase na utilização de material manipulável. Caracteriza-se como uma pesquisa qualitativa e teve como instrumentos de coleta de dados a observação e os registros escritos dos estudantes durante a experimentação da proposta didática. Os sujeitos participantes da pesquisa foram nove estudantes de uma turma do primeiro ano do Ensino Médio de uma escola pública localizada em Niterói-RJ. O referencial teórico foi a Teoria dos Campos Conceituais e as considerações sobre o uso dos materiais manipuláveis. Ao término da investigação, conclui-se que a utilização dos materiais manipuláveis exerce grande motivação sobre o estudante,promovendo o seu envolvimento com a aula. Entretanto, sua utilização, ainda que com a mediação adequada do professor, não é suficiente para a construção do conceito de radiano. Conjectura-se que a complexidade do conceito de radiano, sua especificidade enquanto unidade de medida e a necessidade de outras situações envolvendo tal conceito tenham contribuído para esse fato.
