A técnica e a estética da "conformação"
Authors: Marzochi Samira Feldman 
Published: April 2021

O ensaio relaciona técnica e estética como faces do mesmo processo de formação e "conformação" da cultura e do pensamento, que forja a sociedade em todas as dimensões (histórica, econômica, social, individual, política, cultural). Técnica e estética evidenciam a inseparalidade dos aspectos "material" e "espiritual" e seus derivados: "concreto" e "abstrato", "natural" e "cultural", "real", "virtual", etc. A técnica, sozinha, informa muito pouco sobre ela e suas implicações, do mesmo modo que a estética, restrita ao estudo das obras de arte, talvez não contribua muito para o aprimoramento do prórprio conceito. Isso se deve, inclusive, ao problema que hoje é distinguir a "obra de arte" de outras manifestações estéticas de qua a publicidade, por exemplo, está recheada. O objetivo é lançar a ideia de uma teoria estética das técnicas de conformação em ciências sociais.

Authors: Date Hiroaki , Mizoguchi Tomohiro , Ishikawa Kiichiro 
Published: April 2021

The application of digital geometry processing is undergoing an extension from small industrial products to large-scale structures and environments, including plants, factories, ships, bridges, buildings, forests, and indoor/outdoor/urban environments. This extension is being supported by recent advances in long-range 3D laser scanning technology. Laser scanners are mounted on various platforms, such as tripods, wheeled vehicles, airplanes, and UAVs, and the laser scanning systems are used to efficiently acquire dense and accurate digitized 3D data of the geometry, called point clouds, of large-scale structures and environments. As another technology for the acquisition of digital 3D data of structures and environments, 3D reconstruction methods from digital images are also attracting a great deal of attention because of their flexibility.
The utilization of digital 3D data for various purposes still has many challenges, however, in terms of data processing. The extraction of accurate and meaningful information from the data is an especially important and difficult problem, and many studies on object and scene recognition are being conducted in many fields. How to acquire useful and high-quality digital 3D data of large-scale structures and environments is another problem to be solved for digital geometry processing to be widely used.
This special issue addresses the latest research advances in digital geometry processing for large-scale structures and environments. It covers a broad range of topics in geometry processing, including new technologies, systems, and reviews for 3D data acquisition, recognition, and modeling of ships, factories, plants, forests, river dikes, and urban environments.
The papers will help the readers explore and share their knowledge and experience in technologies and development techniques in this area. All papers were refereed through careful peer reviews.

Technology use in secondary level of English language teaching: A Literature Review
Authors: Luthfiyyah Roghibatul , Hafifah Gusti Nur , Ivone Francisca Maria , Tresnadewi Sintha 
Published: April 2021

Technology has been widely used in the education field, especially for teaching language. Many teachers and students believe in the advantages of technology to enhance language learning. There have been many studies investigating the use of technology in secondary language classrooms. Some studies approve that technology can be applied to increase students' language competence. This paper comprehensively analysed the use of technology for English language teaching in the secondary level based on empirical studies. It reviews 57 articles from reputable journals and publishers. The existing literature shows that studying and reviewing the use of technology in ELT leads to a deeper understanding of its potential benefits. Many technology tools have been utilized to support the teaching of English skills. Kinds of learning activities that require technological tools and applications, such as presentation, discussion, assessment are also discussed. Additionally, problems and solutions encountered in the implementation of technology in secondary ELT levels are scrutinized in this study.
HIGHLIGTS:

Scholars need to set the content and pedagogy first before the technology to obtain meaningful and contextual experiments and discussion in academic circumstances.
The finding unveils a fact that technology use in the ELT context contributes more to students' learning strategies, such as learning motivation, engagement, collaborative work, rather than the improvement of students' learning outcomes.
This finding can be a rationale to rectify the common logical fallacy encountered among studies that claimed that technology can improve particular language skill.
Incorporating culture and textbook adaptation practice for promoting intercultural competence in ELT: Teachers’ perspectives
Authors: Novita Dian , Purwati Oikurema 
Published: April 2021

It is currently accepted that language and culture are inseparable since culture becomes an essential aspect of learning a foreign language. In the Indonesian context, this broad understanding of the crucial role of culture in English teaching has raised challenges in different contexts for EFL teachers. The recent study focuses on Indonesian Junior High School teachers’ views on integrating culture in ELT and practices of textbook adaptation to help students build intercultural competence. Therefore, to meet these aims, a questionnaire and an open-ended question were employed to collect the data from fifteen participants teaching English at public and private schools in Indonesia. The study results reveal that Indonesian EFL teachers have positive attitudes on integrating intercultural competence in ELT. Still, some of the difficulties confronted by their implementation of textbook adaptation have been highlighted in promoting intercultural competence. This study suggests that EFL teachers in Indonesia should be provided with teacher training relating to textbooks adaptation and teaching culture. The implementation of ICT in ELT classrooms is also recommended. Finally, the redesign of the curriculum with more integrated intercultural competency materials should be taken into account.
HIGHLIGHTS:

The EFL teachers’ practices deal with textbook adaptation are not well implemented, although they believe that cultural competence in their teaching activities is crucial.
The English curriculum should give more room for teachers in serving the students based on their needs, preferences, and skills, especially for enhancing students’ mastery on the target language.

Abstract
The present study aimed to evaluate the effects of dietary copper nanoparticles (Cu-NPs) and vitamin C (VC) supplementations on rainbow trout (Oncorhynchus mykiss) juveniles. Six trial diets were supplemented with Cu-NPs and VC including 0/0 (T1, control diet), 0/250 (T2), 0/500 (T3), 2/250 (T4), 2/500 (T5), and 2/0 (T6) mg Cu-NPs/VC per kg diet. After the feeding trial for 60 days, the fish were challenged with Yersinia ruckeri and the survival rate was calculated for 15 days. Based on the data analysis, weight gain (WG), feed conversion ratio (FCR), specific growth rate (SGR), protein efficiency ratio (PER), lysozyme, alternative complement activity (ACH50), catalase (CAT), glutathione peroxidase (GPX), hematocrit (Hct) and mean corpuscular volume (MCV) were significantly (p < 0.05) affected by the Cu-NPs factor. Meanwhile, VC was a significant factor for hemoglobin (Hb) and superoxide dismutase (SOD) (p < 0.05). The results showed that the Cu-NPs and/or VC-supplemented diets improved WG, FCR, SGR, PER, lysozyme, ACH50, SOD, CAT, GPX, Hb, Hct, and MCV when compared with the control group (p < 0.05). The expressions of TNF-α, IL-1ß, IL-10, SOD, CAT, and GPX genes were significantly (p < 0.05) decreased in the fish fed on T3, T4, and T5 diets versus the control. In addition, the dietary Cu-NPs and VC supplementations significantly enhanced resistance against pathogens and led to the control of infection in rainbow trout. In conclusion, Cu-NPs and VC administered as feed additive at 2/250–500 mg/kg elevated the growth performance, antioxidant capacity, and health of rainbow trout.

Abstract
Background. The prognostic value of lactate dehydrogenase (LDH) in colorectal cancer patients has remained inconsistent between non-metastatic and metastatic settings. So far, very few studies have included LDH in the prognostic analysis of curative-intent surgery for colorectal liver metastases (CRLM).Patients and Methods. 580 consecutive metastatic colorectal cancer patients who underwent curative-intent CRLM resection from Blinded for peer review (434 patients) and Blinded for peer review (146 patients) treated in 2000-2019 were enrolled. Overall survival (OS) was the primary endpoint. Cox regression model was performed to identify the prognostic values of preoperative serum LDH levels and other clinicopathology variables. A modification of the established Fong CRS scoring system comprising LDH was developed within this Chinese population.Results. At the median follow-up time of 60.5 months, and median OS was 59.5 months in the pooled cohort. In the multivariate analysis, preoperative LDH > upper limit of normal (250 U/L) was the strongest independent prognostic factor for OS (HR 1.73, 95% confidence interval [CI], 1.22-2.44; P < .001). Patients with elevated LDH levels showed impaired OS than patients with normal LDH levels (27.6 months vs. 68.8 months). Five-year survival rates were 53.7% and 22.5% in the LDH-normal group and LDH-high group, respectively. Similar results were also confirmed in each cohort. In the subgroup analysis, LDH could distinguish the survival regardless of most established prognostic factors (number and size of CRLM, surgical margin, extrahepatic metastases, CEA and CA19-9 levels, etc.). Integrating LDH into the Fong score contributed to an improvement in the predictive value. Conclusion. Our study implicates serum LDH as a reliable and independent laboratory biomarker to predict the clinical outcome of curative-intent surgery for CRLM. Composite of LDH and Fong score is a potential stratification tool for CRLM resection. Prospective, international studies are needed to validate these results across diverse populations.
The interaction of migration range, regional economic development level on social capital and public health services of internal migrants: evidence from the China Migrant Dynamic Survey in 2017
Authors: Yang Zhen , Jiang Chenghua 
Published: April 2021

Abstract
Objectives Studies have confirmed that both migration range (MR) and regional economic development level (REDL) have significant impacts on the accessibility of National Essential Public Health Services (NEPHS) for the internal migrants (IMs), but no studies have explored the interaction between MR and REDL, nor discussed the mechanism behind their influence.Method A sample of 115412 respondents from the China Migrant Dynamic Survey in 2017 was adopted, aged 18-59 years and residence duration more than one year. Beijing, Tianjin and Shanghai were excluded. The MR was divided into inter-provincial and intra-provincial migration. Social capital (SC) was divided into cognitive social capital (CSC) and structural social capital (SSC). The REDL was divided into high income provinces (HIPs) and low-middle income provinces (LMIPs). Cross-table, chi-square test, logistic regression and other statistical methods were used to analyze impacts of MR and REDL on IMs' SC, awareness of NEPHS and establishment of health records (EHR).Results (1) The SC of inter-provincial IMs is always lower than that of intra-provincial IMs. The CSC of IMs in HIPs is lower but their SSC is not the same. The MR difference of IMs' SC is greater in HIPs. (2) The IMs' level of NEPHS utilization in the inter-provincial group and the HIPs group is lower, and the MR difference of IMs' level of NEPHS utilization is greater in the HIPs. (3) The IMs' SC can significantly promote their NEPHS utilization level, but this relationship is affected by the dimensions of SC, MR and REDL.Conclusions MR and REDL may affect the IMs' SC through cultural exclusion and institutional exclusion, and further affect the IMs' NEPHS utilization. When promoting equalization of NEPHS in HIPs, it is necessary for HIPs to expand more primary health facilities to increase the NEPHS supply, and take measures to stimulate the inter-provincial IMs' sense of identity and social participation.
Stochastic finite element analysis of the diametral compression test of powder compacts and porous materials
Authors: Alvarado-Contreras Jose Andres , Lopez-Inojosa Alexis Andres 
Published: April 2021

Abstract
This paper presents a stochastic finite element approach for modeling the mechanical behavior of powder compacts and porous materials under diametral compression test conditions. The main goal is assessing the validity of the diametral compression test as an indirect technique to estimate tensile strengths of brittle or quasi-brittle materials exhibiting porosity heterogeneity. Thus, the study seeks to predict the influence of porosity randomness on stress distributions and the spatial location of the highest tensile stress on thin disc-shaped specimens. The proposed formulation uses a stochastic framework that couples a random spatial field to the finite element analysis to include non-deterministic features. Two case studies consider comparable targets for the mean porosity but different coefficients of variations. For each case study, a total of 1000 realizations are conducted under identical loading and boundary conditions. The predicted stress distributions are compared to the ones from homogenous closed-form solutions from the literature. Then, the expected magnitude and location of the maximum tensile stress are evaluated by statistical means. Findings from the stochastic model show that porosity randomness induces stress concentration around less dense volumes and location deviation of the maximum tensile stress from the center of the discs. Likewise, porosity heterogeneity could affect the accuracy of experimental diametral compression tests even for small variance cases; and so, the reliability of the mechanical properties derived from models based exclusively on the classic assumption of material homogeneity.
