Authors: Sevilla Veronica , Inga Xavier , Castro Felipe , Aguilar Jose
Published: November 2018

Abstract: The third molars are the dental organs with the most variations in terms of their formation and time of eruption, which can cause several pathologies. The incidence of third molar impaction varies between 20% and 30%, with predominance in females. Through the inferior dental canal, goes the inferior dental nerve to innervate the molars and lower premolars. Recent studies on variations in the position of the lower dental canal have shown a low incidence of variations. Objective: To determine the prevalence of anatomical variations of the inferior dental canal in relation to impacted lower third molars, by means of digital image analysis in patients who attended the X-Ray Imaging Center in Azogues in 2016. Materials and Methods: A cross-sectional study was conducted on patients who attended the center X-Ray Imaging Center in Azogues in 2016. The following variables were analyzed: sex, age, variation of the position of the inferior dental canal in relation to the third impacted molar, the radiographic details according to the Monaco classification, and tooth position according to the Winter classification. In total, 64 radiographs were analyzed. Results: It was found that 5% of participants showed no relation of the inferior dental canal with the lower third molar, 72% had a relation of the dental canal with the third molar, and 23% presented with absence of the third molar. According to the Winter classification, the prevalence was 53% mesioangular, 18% horizontal, 19% vertical, 6% vestibuloversion, and 4% inverted. Conclusion: The third molars present high indexes of relation with the inferior dental canal in 18- to 29-year-old Ecuadorians.

Abstract: Negative attitudes mean a barrier for People with Disability (PwD), but attitudes towards Deaf people are structurally different from the rest of the PwD. The aim of this study is to evaluate the factorial structure and internal reliability of the Attitudes towards Deafness Scale (ADS) applied in health professionals from Concepcion, Chile. The ADS was translated to Spanish and back-translated to English, then reviewed by public health experts, and a pilot application was carried out to 15 health professional to make final modifications. The Chilean ADS version was applied to 182 health professional from primary care centers and academics working in health schools. Reliability analysis with estimation of the Cronbach’s alpha coefficient, and exploratory factor analysis were made. The data presented adequate values to perform exploratory factor analysis (KMO=0.73; Bartlett’s sphericity test p <0.00001). A maximum likelihood extraction method and a Quartimax rotation method with Kaiser standardization were used for a four-factor model, in which 11 items presented loads of less than 0.5, so the final model was left with 11 items. A Cronbach’s alpha coefficient of 0.70 was determined in the final model, with an alpha of 0.77 for the first factor, 0.55 for the second, 0.77 for the third, and 0.61 for the fourth. The exploratory factor analysis suggested a four-dimensional structure for ADS Chilean version. The four subscales and the scale in general presented an adequate Cronbach’s alpha, suggesting acceptable internal consistency.
LIBERDADE E NATUREZA HUMANA EM MAQUIAVEL
Authors: Ruzza Antonio
Published: November 2018

Maquiavel se apresenta como o filósofo mais representativo das mudanças ocorridas na passagem entre a Idade Média e a Idade Moderna. Pela leitura das suas obras que tratam de política e moral, leitura livre dos conhecidos preconceitos que elas suscitaram na sua época, verificamos que ele, a partir do estudo da História (tanto greco-romana quanto medieval), desenvolve um conceito original de liberdade, que consegue conciliar o elemento coletivo / público e o individual / privado, sendo esse último um traço dominante na futura sociedade industrial. Ele apresenta uma concepção realista e pessimista da natureza humana, que se caracteriza pelos desejos, o espírito conflitivo e a ambição. Essas características não podem ser freadas nem eliminadas (como pensavam Platão, Aristóteles, Agostinho, etc.), mas devem ser oportunamente aproveitadas e endereçadas para o bem comum (república). Assim, Maquiavel inicia a dissolução de toda uma tradição filosófica e político-moral.
Hannah Arendt e o resgate do conceito de totalitarismo
Authors: Furtado Márcio Roberto Malcher
Published: November 2018

Tendo em vista os inumeráveis empregos do conceito totalitário arendtiano no senso comum, o presente artigo tem por finalidade resgatar tal conceito para que o mesmo seja aplicado acertadamente no contexto sociopolítico atual. Portanto, o conceito foi abordado via a obra Origens do Totalitarismo (1951), na qual o fenômeno do totalitarismo foi esquadrinhado e meticulosamente analisado pela teórica política Hannah Arendt. A pensadora procurou compreender como foi possível ocorrer o fenômeno totalitário, assim como quais foram os elementos que contribuíram para o seu surgimento. Muito embora o conceito arendtiano seja mais bem aplicável dentro de seu tempo e espaço, pretende-se resgatar os princípios básicos norteadores delineados pela escritora, a fim de melhor compreender o desenvolvimento da questão na contemporaneidade.

Published: November 2018

Agricultural waste such as rice straw, rice husk and rice husk ash have not been utilized properly. This waste of agricultural produce can actually be used as an alternative to bionanofiller because it contains an excellent source of silica. The silica content contained in the rice waste when combined with the polymer matrix can produce composites having high thermal and mechanical properties. Characterization of bionanofiller from this rice waste is done by SEM, XRF, FTIR, XRD and particle density. The result of SEM analysis from this rice waste is feasible to be used as filler because it has size 1 μm. Likewise with the results of XRF analysis that rice waste contains a high enough silica component that is 80.6255% - 89.83%. FTIR test results also show that bionanoparticles from rice waste have the same content of silica. In the XRD analysis the best selective gain of rice waste is found in rice husk ash which is characteristic of amorp silica at a range of 2ϴ = 22
. The largest density analysis of paddy waste was found in rice husk 0.0419 gr / cm , followed by rice straw by of 0.0417 gr / cm 3 and rice hulk ash 0.0407 g / cm 3

Debate on Genetic Resources Accessed Ex Situ in the context of the Nagoya Protocol
Authors: Arjjumend Hasrat
Published: November 2018

Recently enacted two international laws – Nagoya Protocol on access and benefit sharing (ABS) and International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) – deal with the access/utilization of and benefit sharing arising out from genetic resources and associated traditional knowledge (TK). Both the instruments lack relevant appropriate provisions guiding the countries to take administrative or legislative measures for covering and addressing the benefit sharing from the ex situ collections of genetic resources that were accessed well before the Nagoya Protocol came into existence. Developed nations show no willingness to share the benefits arising from the biological resources which they accessed from developing countries and retain ex situ. As a result, most affected entity would be the indigenous people and local communities (ILCs) – the custodians of most of the local biological resources – who would receive no benefits. The implications on this crucial issue will be critically reviewed in this article to identify appropriate solutions to this bottleneck using a few case studies.

Understanding of concepts is measured by student activity in class and learning outcomes. Data was collected by tests and observations. Data was processed and analyzed by descriptive analysis and simple statistical test. The results showed that the use of experimental methods can improve the understanding of students about the concept of simple aircraft. The use of experimental methods increases students’ activity and learning outcomes. Increased student learning activity seen from the increasing percentage of students who ask questions, working together in groups, able to conduct experiments independently, cleaning and storing tools and materials that have been used in the experiment, and deliver the results of experiments. The results showed that the mean grade increased from 47,5 (before action) to 60,5 (cycle I) and 75,0 (cycle II). The percentage of completed students in learning also increased from 45,0% (before action) to 60,0% (cycle I) and 85,0% (cycle II). Thus, the experimental method can be an alternative in improving students' understanding of the concept in science subjects.

It’s Always a Women’s Problem! Micro-Entrepreneurs, Work-Family Balance and Economic Crisis
Authors: Cesaroni Francesca Maria , Pediconi Maria Gabriella , Sentuti Annalisa
Published: November 2018

Gender inequality in the division of family work is vastly corroborated and work–family balance is an important topic in the female entrepreneurship field of research. Even if work–family balance should be a necessity indiscriminately perceived by all women and men who have a paid job, it is a particularly pertinent issue for women, called to find equilibrium between work and family. This study analyses the situation of men and women entrepreneurs in order to investigate how the economic crisis affected the work–family balance. A survey was conducted on a sample of 218 men and women sole-proprietors. Findings show that the work–family balance of women entrepreneurs does not seem to have been particularly affected by the crisis. However, some differences between men and women remain. Concerning balance, as expected, only women stated that they personally take care of the house and family. Different perceptions of the crisis between men and women also emerged, as a consequence of gender stereotypes. Women entrepreneurs have greater difficulty in having an internal psychological balance of the double role than men, who are more involved in the implementation of external balance and focus on corporate and social provisions.
Development of Image Processing for Crack Detection on Concrete Structures through Terrestrial Laser Scanning Associated with the Octree Structure
Authors: Cho Soojin , Park Seunghee , Cha Gichun , Oh Taekeun
Published: November 2018

Terrestrial laser scanning (TLS) provides a rapid remote sensing technique to model 3D objects but can also be used to assess the surface condition of structures. In this study, an effective image processing technique is proposed for crack detection on images extracted from the octree structure of TLS data. To efficiently utilize TLS for the surface condition assessment of large structures, a process was constructed to compress the original scanned data based on the octree structure. The point cloud data obtained by TLS was converted into voxel data, and further converted into an octree data structure, which significantly reduced the data size but minimized the loss of resolution to detect cracks on the surface. The compressed data was then used to detect cracks on the surface using a combination of image processing algorithms. The crack detection procedure involved the following main steps: (1) classification of an image into three categories (i.e., background, structural joints and sediments, and surface) using K-means clustering according to color similarity, (2) deletion of non-crack parts on the surface using improved subtraction combined with median filtering and K-means clustering results, (3) detection of major crack objects on the surface based on Otsu’s binarization method, and (4) highlighting crack objects by morphological operations. The proposed technique was validated on a spillway wall of a concrete dam structure in South Korea. The scanned data was compressed up to 50% of the original scanned data, while showing good performance in detecting cracks with various shapes.
Waveguided Approach for Difference Frequency Generation of Broadly-Tunable Continuous-Wave Terahertz Radiation
Authors: De Regis Michele , Consolino Luigi , Bartalini Saverio , De Natale Paolo
Published: November 2018

The 1–10 terahertz (THz) spectral window is emerging as a key region for plenty of applications, requiring not yet available continuous-wave room-temperature THz spectrometers with high spectral purity and ultra-broad tunability. In this regard, the spectral features of stabilized telecom sources can actually be transferred to the THz range by difference frequency generation, considering that the width of the accessible THz spectrum generally scales with the area involved in the nonlinear interaction. For this reason, in this paper we extensively discuss the role of Lithium Niobate (LN) channel-waveguides in the experimental accomplishment of a room-temperature continuous wave (CW) spectrometer, with μW-range power levels and a spectral coverage of up to 7.5 THz. To this purpose, and looking for further improvements, a thought characterization of specially-designed LN waveguides is presented, whilst discussing its nonlinear efficiency and its unprecedented capability to handle high optical power (107 W/cm2), on the basis of a three-wave-mixing theoretical model.

Published: November 2018

The application of recycled aggregate concrete (RAC) has developed rapidly in recent years. But how to evaluate the residual properties of RAC after the fires is more beneficial to the further popularization and application of RAC. This paper presents the residual properties of RAC and steel reinforced recycled aggregate concrete (SRRAC) components after exposure to elevated temperature. A total of 176 specimens (120 rectangular prisms specimens, 24 SRRAC short columns and 32 SRRAC beams) were designed and tested after exposure to elevated temperature. The parameters were considered in the test, including replacement percentage of recycled coarse aggregate (0%, 30%, 50%, 70% and 100%) and exposure to different temperatures (20, 200, 400, 600 and 800 degrees centigrade). According to the test results, heat damage and residual properties of specimens were analyzed in detail, such as surface change, mass loss, bearing capacity degradation, stiffness degradation, ductility and energy dissipation of specimens under the elevated temperature. The results showed that a series of significant physical phenomena occurred on the surface of RAC and SRRAC components after exposure to elevated temperature, such as the color changed from green-grey to gray-white, chapped on the concrete surface after 400 degrees centigrade and the mass loss of concrete is less than 10%. The degradation of mechanical properties degenerated significantly with the increase of temperature, such as the strength of RAC, and compressive capacity, bending capacity, shear capacity and stiffness of SRRAC components, among that, the degradation of the strength of RAC was most obvious, up to 26%. The ductility and energy dissipation of SRRAC components were insignificant affected by the elevated temperature. Mass loss ratio, peak deformation and bearing capacity showed a slight increase trend with the increase of replacement percentage. But the stiffness showed significant fluctuation when replacement percentage was 70% to 100%. And the ductility and energy dissipation showed significant fluctuation when replacement percentage was 30% to 70%.

Silicon carbide (SiC), especially 4H-SiC, is an ideal semiconductor in power electronics due to its outstanding electrical and thermal properties. It has high hardness and brittleness, which makes it difficult to machine. To understand the nanomachining characteristics of off-axis 4H-SiC and provide suggestions on 4H-SiC substrate thinning, the nanocutting process of 4 ∘ off-axis 4H-SiC was simulated by molecular dynamics. The results showed that the stacking fault induced by cutting propagates in the basal plane, and propagates deep into the SiC workpiece when the angle between the cutting direction and the c-axis is smaller than 90 ∘ . Bond reconstruction is found near the slip plane. The cutting depth is also a key parameter in nanocutting. With smaller cutting depth, machining is more like scratching than cutting. With larger cutting depth, more atoms are involved in the cutting, cutting force and workpiece temperature are higher, and more defects exist.

We investigated particulate flows by coupling simulations of the three-dimensional incompressible Navier–Stokes equation with the immersed boundary method (IBM). The results obtained from the two-way coupled simulation were compared with those of the one-way simulation, which is generally applied for clarifying the particle kinematics in industry. In the present flow simulation, the IBM was solved using a ghost–cell approach and the particles and walls were defined by a level set function. Using proposed algorithms, particle–particle and particle–wall collisions were implemented simply; the subsequent coupling simulations were conducted stably. Additionally, the wake structures of the moving, colliding and rebounding particles were comprehensively compared with previous numerical and experimental results. In simulations of 50, 100, 200 and 500 particles, particle–wall collisions were more frequent in the one–way scheme than in the two-way scheme. This difference was linked to differences in losses in energy and momentum.

The aim of this study was to evaluate and compare the efficacy of 4-hexylresorcinol (4-HR)-incorporated silk as a vascular patch scaffold to that of the commercial polytetrafluoroethylene (PTFE) vascular patch (GORE® ACUSEAL). The expression of the vascular endothelial cell growth factor-A (VEGF-A) after application of 4-HR was studied in RAW264.7 and HUVEC cells. In the animal study, a carotid artery defect was modeled in Sprague Dawley rats (n = 30). The defect was directly closed in the control group (n = 10), or repaired with the PTFE or 4-HR silk patch in the experimental groups (n = 10 per group). Following patch angioplasty, angiography was performed and the peak systolic velocity (PSV) was measured to evaluate the artery patency. The application of 4-HR was shown to increase the expression of VEGF-A in RAW264.7 and HUVEC cells. The successful artery patency rate was 80% for the 4-HR silk group, 30% for the PTFE group, and 60% for the control group. The PSV of the 4-HR silk group was significantly different from that of the control group at one week and three weeks post-angioplasty (p = 0.005 and 0.024). Histological examination revealed new regeneration of the arterial wall, and that the arterial diameter was well maintained in the 4-HR silk group in the absence of an immune reaction. In contrast, an overgrowth of endothelium was observed in the PTFE group. In this study, the 4-HR silk patch was successfully used as a vascular patch, and achieved a higher vessel patency rate and lower PSV than the PTFE patch.

Down syndrome (DS) is the most common genetically-defined cause of intellectual disability. Neurodevelopmental deficits displayed by individuals with DS are generally global, however, disproportionate deficits in cognitive processes that depend heavily on the hippocampus and prefrontal cortex are also well documented. Additionally, DS is associated with relative strengths in visual processing and visuospatial short-term memory, and weaknesses in the verbal domain. Although reports of pharmacological rescuing of learning and memory deficits in mouse models of DS abound in the literature, proving the principle that cognitive ability of persons with DS can be boosted through pharmacological means is still an elusive goal. The design of customized batteries of neuropsychological efficacy outcome measures is essential for the successful implementation of clinical trials of potential cognitive enhancing strategies. Here, we review the neurocognitive phenotype of individuals with DS and major broad-based test batteries designed to quantify specific cognitive domains in these individuals, including the one used in a pilot trial of the drug memantine. The main goal is to illustrate the essential considerations in planning trials to enhance cognitive functions in individuals with DS, which should also have implications for the design of similar studies in individuals with other forms of intellectual disability.

Employees’ working relationships were long determined to be crucial to their overall wellbeing and performance ratings at work. However, a few studies were found to examine the effects of positive workplace relationships on employees’ working manners. This study aimed to investigate the effects of healthy workplace relationships on employees’ working behaviors, which in turn affect their performance. In doing so, an integrated model was developed to examine the primary performance drivers of nurses in Vietnamese hospitals and focus on the effects of high-quality workplace relationships on the working attitudes of the staff. This study analyzed a questionnaire survey of 303 hospital nurses using a structural equation modeling approach. The findings demonstrated the positive effects of high-quality workplace relationships on working manners including higher commitment, lower level of reported job stress, and increased perception of social impact. Notably, the results also demonstrated that relationships between leaders and their staff nurses make a significant contribution to the quality of workplace relationship and nurses’ performance. In addition, the social impact was illustrated to positively moderate the association between healthy workplace interactions and job stress; however, it had no significant effect on job commitment. Unfortunately, job commitment was surprisingly found to not be related to performance ratings. This paper provides some suggestions for the divergence of performance drivers in the hospital context in Vietnam.

The efficient reduction of CO2 into valuable products such as methanol, over metal-organic frameworks (MOFs) based catalyst, has received much attention. The photocatalytic reduction is considered the most economical method due to the utilization of solar energy. In this study, Copper (II)/Zeolitic Imidazolate Framework-8 (Cu/ZIF-8) catalysts were synthesized via a hydrothermal method for photocatalytic reduction of CO2 to methanol. The synthesized catalysts were characterized by X-ray Photoelectron Spectroscopy (XPS), Field Emission Scanning Electron Microscopy (FESEM) coupled with Energy Dispersive X-ray (EDX), Ultraviolet-visible (UV-vis) spectroscopy, and X-Ray Diffraction (XRD). The host ZIF-8, treated with 2 mmol copper prepared in 2M ammonium hydroxide solution showed the highest photocatalytic activity. The crystal structures of ZIF-8 and 2Cu/ZIF-8N2 catalysts were observed as cubic and orthorhombic, respectively and the XPS analysis confirmed the deposition of Cu (II) ions over ZIF-8 surface among all the prepared catalysts. The orthorhombic structure, nano-sized crystals, morphology and Cu loading of the 2Cu/ZIF-8N2 catalyst were the core factors to influence the photocatalytic activity. The yield of Methanol was found to be 35.82 µmol/L·g after 6 h of irradiations on 2Cu/ZIF-8N2 catalyst in the wavelength range between 530–580 nm. The copper-based ZIF-8 catalyst has proven as an alternative approach for the economical photocatalytic reduction of CO2 to CH3OH.

Alcoholic fatty liver disease (AFLD) is characterized by an abnormal accumulation of lipid droplets (LDs) in the liver. Here, we explore the composition of hepatic LDs in a rat model of AFLD. Five to seven weeks of alcohol consumption led to significant increases in hepatic triglyceride mass, along with increases in LD number and size. Additionally, hepatic LDs from rats with early alcoholic liver injury show a decreased ratio of surface phosphatidylcholine (PC) to phosphatidylethanolamine (PE). This occurred in parallel with an increase in the LD association of perilipin 2, a prominent LD protein. To determine if changes to the LD phospholipid composition contributed to differences in protein association with LDs, we constructed liposomes that modeled the LD PC:PE ratios in AFLD and control rats. Reducing the ratio of PC to PE increased the binding of perilipin 2 to liposomes in an in vitro experiment. Moreover, we decreased the ratio of LD PC:PE in NIH 3T3 and AML12 cells by culturing these cells in choline-deficient media. We again detected increased association of specific LD proteins, including perilipin 2. Taken together, our experiments suggest an important link between LD phospholipids, protein composition, and lipid accumulation.
