Drogadição: o que lemos na revista?
Authors: Ribeiro-Andrade Erica  Henrique , Alberico Gabriela Fagundes Altoé , Silva Pedro Henrique de Almeida , Freitas Millena Gomes Mambreu de
Published: April 2021

A intenção desta pesquisa é o de apresentar a avaliação do perfil das informações sobre drogadição veiculadas na Revista VEJA, tentando compreender a forma de produção de subjetividades nas mesmas. Analisou-se todas revistas VEJA publicadas nos últimos três anos, compreendendo as edições de janeiro de 2016 até julho de 2019. Era fundamental que a matéria publicada apresentasse informações de qualquer tipo sobre drogas, drogadição ou estudos envolvendo substâncias químicas ilícitas. Quanto as drogas lícitas, à exceção de matérias sobre álcool e tabaco, manteve-se na amostra somente os estudos que associavam as substâncias à uma realidade de dependência. Ao final da aplicação destes filtros, vinte e oito matérias foram localizadas, lidas na íntegra e organizadas numa tabela contendo a data e a edição da revista, o título da matéria e a ideia central apresentada. Desenvolveu-se uma análise de cada uma das matérias associadas aos analisadores. Foi possível confirmar a ideia de uma imagem negativa do uso de substâncias químicas no imaginário social.  Destaca-se o fato de que as publicações sobre as celebridades em sua relação com as drogas ganham maior proeminência do que matérias sobre prevenção ou tratamento. As menções ao cigarro eletrônico expressavam tanto benefícios do uso por um viés de redução de danos, quanto os malefícios do uso e a possibilidade de desenvolvimento de novas adicções. Todavia a completa inexistência de matérias sobre as diversas modalidades de tratamento e reabilitação do sujeito drogadicto, pode indicar, ainda que não exclusivamente, uma negligência deste importante veículo de informação.

Published: April 2021

Esse artigo tem como objetivo identificar as expectativas de acadêmicos do curso de enfermagem, frente ao primeiro contato com o estágio curricular supervisionado no setor de trauma e emergência e as influências que ele exerce no futuro do egresso profissional. O estudo é uma avaliação qualitativa de caráter exploratória descritiva, que teve como público acadêmicos regularmente matriculados na 4ª ou 8ª fase do curso de enfermagem. O Estágio Curricular Supervisionado constitui um ambiente propício ao aprendizado da profissão e desenvolvimento de competências, entretanto, faz-se necessário maior entendimento do que esse momento representa na formação do futuro profissional enfermeiro. Entretanto, ainda há a existência de um déficit no contexto de aprendizado na visão dos alunos, de forma a atender às necessidades da atenção integral no setor de trauma e urgências, além da identificação de uma dissociação entre os campos da teoria, pratica e estágio que contribui para o surgimento de lacunas na formação. O aluno deve buscar mais conhecimento e se dedicar por completo ao estágio como um momento de complementar o aprendizado e formar seu senso crítico e profissional.

Objetivo: Descrever e revisar como a cirurgia ortognática pode afetar o sistema estomatognático, evidenciando a importância da fisioterapia pós-operatória durante o período de reabilitação. Revisão bibliográfica: A cirurgia ortognática pode diminuir a amplitude dos movimentos mandibulares, diminuir a força dos músculos da mastigação, piorar a função velofaríngea e causar alterações neurosensoriais de diferentes níveis. Pacientes orientados a realizar fisioterapia após a cirurgia apresentaram melhoras mais significativas e mais rápidas em relação aos pacientes que não receberam essa orientação. Diversos protocolos de exercícios foram propostos, com diferentes momentos de início, períodos de duração e tipos de exercícios realizados. Considerações finais: Os benefícios da cirurgia ortognática são inquestionáveis, porém ela também gera sequelas pós-operatórias, especialmente na musculatura orofacial e nervos sensitivos da região. Embora não haja um consenso na literatura sobre quando começar ou que tipos de exercícios realizar na fisioterapia pós-cirúrgica, a grande maioria afirma que pacientes que a realizam apresentam melhora das funções musculares de forma mais rápida e mais eficiente.

Objectives:

The usefulness of biomarkers in community acquired pneumonia (CAP) has been under the research light with limited reports from Africa. This study aimed at evaluating the clinical usefulness of serum procalcitonin (PCT) in patients admitted with CAP in a tertiary hospital in Ilorin, Nigeria.

Materials and Methods:

This was prospective single center observational study of 102 admitted patients with clinical and radiologic features of CAP. All the patients had serum PCT assay, complete blood count, blood culture, sputum microbiology, and serological evaluation for atypical pathogens. Repeat PCT assay was done following 1 week of antibiotic therapy. The patients were classified into one of two diagnostic groups: Those with microbiologically confirmed bacterial CAP and those without bacterial CAP.

Results:

Over half (58/102; 56.8%) of the patients had microbiologically confirmed bacterial CAP. The baseline serum PCT concentrations were significantly higher in patients with bacterial CAP when compared to the non-bacterial CAP group (2.55 ± 0.14 vs. 0.94 ± 0.61 ng/ml; P < 0.001). There was also a statistically significant difference between the pre- and post-treatment serum PCT concentrations in the bacterial CAP group (P < 0.001) and the non-bacterial CAP group (P = 0.006). The area under the receiver operating characteristic (AUC) for pre-treatment PCT in diagnosing bacterial CAP was 0.795 (95% confidence level [CI]: 0.709–0.881) with a sensitivity of 67.2% and specificity of 79.5% at an optimal cutoff of 1.5 ng/ml. Overall, the biomarker was independently associated with white cell counts >10 × 109/L (AOR = 6.28; 95% CI: 1.30–30.32, P = 0.02). The baseline mean serum PCT levels were also significantly higher in patients admitted for 7 or more days (P = 0.010).

Conclusion:

Serum PCT had good diagnostic strength in patients admitted with bacterial CAP in Ilorin. The biomarker can also assist clinicians with predicting the pathogenic group and monitoring clinical progress of CAP.

Human rights are basic rights that are inherent in every human being that cannot be reduced at all. This right can only be taken away through legitimate state institutions and with legitimate legal reasons as well, but the increasingly globalized economic flow, and an increasingly advanced social order and leads to industrialization in all fields, creating many new crime models with an increasing trend, one of them is the crime of human trafficking. They are not only adults who are vulnerable to this crime, but it turns out that children are the most vulnerable to this crime, so that their human rights are threatened in all aspects. This study uses a normative juridical method with only the study of laws and literature. The result of the research is that the laws and regulations protecting the human rights of children from human trafficking crimes are inadequate and tend not to be in sync with one another so that they have not been maximized in realizing protection for child victims of human trafficking

Published: April 2021

Dye-Sensitized Solar Cells (DSSC) is photovoltaic with a dye that functions as an acceptor of sunlight. The great potential of using DSSC lies in the ease of the synthesis process, and the dyes used can come from plants. However, like most other solar cells, increasing the operating temperature can degrade the DSSC performance and thus decrease the efficiency. This article presents a model of the relationship between the effect of temperature on DSSC performance. The model proposed is derived from the DSSC equivalence with a diode circuit. By confirming the experimental research results, it is known that the model presented in this study has excellent accuracy on various DSSC performance parameters (R2> 0.99). The performance studied includes the I-V curve's shape, the value of the short-circuit current, the diode leakage current, and the open-circuit voltage. Based on daily temperature data in Pangkalpinang City, the potential performance of the DSSC could also be determined when it was developed in Kep. Bangka Belitung. The short-circuit current value obtained is in the range of 14 A with a voltage of 0.6 V. It is hoped that this proposed model can be information for the development of DSSC because of its enormous potential application in Indonesia.

Authors: Rahardi Kunjana
Published: April 2021

It is always possible to combine the field of language with other fields which may be irrelevant, but there is a possibility to develop the fields synergistically. Cyberpragmatics can be seen as a transdisciplinary field, because it includes complex dimensions, namely language, pragmatics, technology, media, internet, and possibly other dimensions as well. This article aims to describe contexts in cyberpragmatics. The data was collected from utterances in various domains which contained context entities. The substantive data source was taken from authentic texts in various social media which also contained context. As for the locative data source, it was from social media that could be reached within the time of research. The data was collected by applying listening method and interview method. The researcher also used his intuitive judgment given the fact that he is a native speaker of Indonesian language. The data analysis method applied in this research is distributional analysis method in order to reach the linguistic aspects of this research. The dominant analytical method used is the extralingual type of extralinguistic method of analysis. The analysis showed that various pragmatic contexts were found, which include social context, societal context, cultural context, and situational context. The diverse contexts may change and shift over time. The context of the past cannot be the same as the context of the present and future. The elements and functions of the context will definitely shift and change so that the meaning of speech intentions in cyberpragmatics will also change.
PENDEFINISIAN OBJEK DAN PELENGKAP DALAM KAMUS BESAR BAHASA INDONESIA SEBAGAI PENUNJANG LITERASI
Authors: Puspita Dewi , Sutami Hermina
Published: April 2021

Literacy cannot be separated from language skills. The most basic language skills are the ability to compose meaningful utterances. For that purpose, a proper understanding of the sentence-forming elements and their functions is needed. Unfortunately, the definitions of the two sentence element functions, namely objects and complements, in KBBI still overlap. The overlapping definition can confuse language users. This paper aims to clarify the differences between object and complement and to correct the inaccuracies in the definition of these two words. Thus, the definition of each of the two functions becomes more appropriate and easily understood by Indonesian language learners. This research was conducted with a functionalism approach through the analysis of syntactic and semantic functions, by paying attention to lexicographic principles. The analysis was carried out on six naturally occurring sentences. The sentences are taken from the Indonesian web corpus. The results of the data analysis in this study indicate that objects and complements are indeed different. From these differences clear and non-overlapping boundaries are obtained.
SOCIO-CULTURAL DYNAMICS AND ETHNOLINGUISTIC VITALITY OF SEMBIRAN BALINESE
Authors: Pratiwi Desak Putu Eka , Arka I Wayan , Shiohara Asako
Published: April 2021

This paper reports our preliminary findings on the assessment of language vitality of Sembiran Balinese in the larger socio-cultural transformation of contemporary Bali.  Sembiran Balinese, also known as Bali Aga, is a conservative mountain dialect of Balinese spoken by around 5,000 speakers in the Sembiran village, 30 km east of Singaraja northern Bali. The language and its culture reflect Bali in antiquity (Ardika, et al. 1991; Ardika, et al. 1997), with the language quite distinct from Lowland Balinese (Bali Dataran), for example in terms of its pronominal system and the absence of speech level system (Astini 1996, Sedeng 2007, Arka & Sedeng 2018). The study is based on the data collected through questionnaires focusing on subjective views of ethno-linguistic vitality such as in-/out-group interactions and domains of language use in contemporary multilingual settings, supported by ethnographic data. The analysis makes use of the current development in the sociolinguistics of vitality, particularly the notions of ethnolinguistic vitality (Giles, et al 1977) and theories of language shift and endangerment (Grenoble & Whaley 2006, Fishman 1991). The findings reveal that Sembiran Balinese appears to have a relatively strong linguistic vitality even though the speech community itself is a minority group in Bali.
THE TYPOLOGY OF APPLICATIVE/CAUSATIVE MARKING IN TAPUS
Authors: Yanti NFN , McKinnon Tim , Cole Peter , Hermon Gabriella
Published: April 2021

This paper constitutes an initial examination of the applicative/causative suffix -ge in Tapus, a divergent traditional Minangkabau variety spoken in rural Western Sumatra. Our aim is to show that the similarities and divergences from Standard Indonesian of traditional rural varieties provides insight into the properties of “Indonesian-type” languages in general. The distribution of applicatives/causatives in Tapus is interesting for several reasons. First, applicative/causative suffixes in Indonesian-type languages are well-known for the use of the same morphology for a variety of purposes. The fact that a single form is used for these different functions raises the question of whether the applicative/causative morphemes are two (or more) distinct morphemes or whether the form has a unitary linguistic function. We will show that the unitary analysis for causative and benefactive uses of the applicative/causative suffix cannot account for the data in Tapus. Another area of interest with regard to this suffix relates to constraints on movement.  We show that the Extreme Locality Hypothesis cannot account for the Tapus data based on the interaction between the applicative/causative suffix and information question formation/relativization. Finally, we demonstrate that Pylkkänen’s typology of applicatives makes incorrect predictions with respect to the interpretations available for benefactives in Tapus and other Indonesian-type languages, showing the necessity for an expanded taxonomy of applicative forms. Our general conclusion is that the detailed examination of grammatical constructions in divergent Malayic varieties leads to new and surprising insights into the grammatical profile of Indonesian-type languages.

Authors:   Surya University, Indonesia
Published: April 2021

The traditional role of museum is to collect objects and materials of cultural, religious and historical importance, preserve them, research into them and present them to the public for the purpose of education and enjoyment. However, people have started to avoid going there since the atmosphere offered there is monotonous and people would rather choose to easily search for the wanted information through their mobile device. So, in order to raise people’s motivation and effectiveness in learning through museum, gamification method could be implemented in museum visits. Gamification refers to the use of game elements and gamedesign techniques in non-game contexts. Through this research, a gamification system with QR Code technology approach will be created. In order to achieve the system’s goal, Spiral Model is used to develop the application. While to evaluate the learning aspect, two out of four levels of Kirkpatrick model will be used which are reaction and learning.

Corrosion Behaviour of Al-Si Cast Alloy Reinforced with Titanium diboride (TiB2) and Scandium (Sc)
Authors:   Universiti Teknologi MARA, Malaysia
Published: April 2021

The aluminium-silicon (Al-Si) based on Metal Matrix Composites (MMCs) is widely used in lightweight constructions and transport applications requiring a combination of high strength and ductility. A grain refinement plays a crucial role in improving characteristics and properties of Al alloys. In this investigation, titanium diboride (TiB2) and scandium (Sc) inoculants were added to the Al-Si alloys for grain refinement of an alloy. In this investigation, the corrosion resistance rate of Al-Si cast alloy reinforced by TiB2 and Sc were measured by potentiostat (AUTOLAB) instrument. The aim of this research is to investigate the corrosion rate for Al-Si-TiB2-Sc composites that immersed in different concentration of acidic solutions. Besides, the immersion time of acidic solutions also was investigated. All the samples were prepared accordingly for ASTM standard by the composition of 6.0 wt% TiB2 and 0.6wt% Sc. All the samples undergo cold mounting technique for easy handling on corrosion tests. Then the samples were immersed in two different concentrations acidic medium solutions, which were 0.1.and 1.0 M hydrochloric acids (HCl). The corrosion rate also was investigated for immersion samples of 1.0 M HCl for 21 days. From the results obtained, added TiB2 and Sc onto Al-Si alloy gave the better properties in corrosion resistance. Corrosion rates to reduce when the samples were immersed in a lower concentration of acidic medium, 0.1 HCl. However, there are some significant on the result but it still following the corrosion rates trend. Thus, improvements to reinforcement content need to be done in further research to cover the lack of this corrosion rates trend.
An Exploratory Study on the Impact of an Organizational Performance through Lean Production Practices: A Case Study
Authors:   King Mongkut's University of Technology North Bangkok, Thailand
Published: April 2021

Due to globalization, the world has become smaller and smaller with highly intense business competition. Thus, any organization, places more emphasis on looking for ways to survive based on reducing overall costs without decreasing product quality. Hence, identifying inefficient activities are becoming a core way to help manufactures decreasing in the operating costs while gaining a competitive advantage. However, few studies are concerned about searching for root causes of problems that are main obstacles for production improvement. Therefore, the purpose of this study is to explore on the impact of production performance and find a root cause for non-value-added activities through lean production and other quality tools application in a set of companies via a case study of SMEs. In short, bottleneck areas were identified for each company, and the problems were removed through increasing the processing time at those areas. The findings shows that motion and process wastes, compared to other wastes, are the main impacts for obstacles in production performance caused by poor workplace organization and lack of standardized work. The biggest barrier to lean production implementation is decentralization and changing the culture of workers, which requires the agreement of the top manager and involves of everyone in the entire SMEs.
Development of a Rapid Manufacturing Process for Concave and Convex Lens Arrays
Authors:   National Kaohsiung University of Applied Sciences, Taiwan
Published: April 2021

This paper reports a rapid manufacturing process for the production of concave and convex lens arrays on the polymer substrate. In this method, many small steel balls with highly polished surfaces were placed in a rectangular cavity to form a closely packed small steel ball array. Then, a polymer substrate (PMMA sheet) was placed on top of the small steel ball array, and the stack of the PMMA sheet and the small steel ball array was placed in a hot embossing machine. During the hot embossing process operation, a concave lens array pattern is directly fabricated onto a polymer substrate. In addition, the diameter and depth of the concave lens array can be changed and controlled by adjusting the processing conditions of the hot embossing process. Thus, concave lens arrays with different dimension can be fabricated. Next, the polymer substrate with concave lens array pattern can be used as a mold for rapid replication of polymer convex lens array using vacuum-assisted UV molding process. In this way, various concave and convex lens arrays can be rapid fabricated with high throughput and low cost.

Authors:   Silesian University of Technology, Poland
Published: April 2021

Photogrammetry allows a three-dimensional reconstruction of the object based on its multiple photography’s. The quality of the reconstruction result depends mostly on the gloss, the diversity of the texture, the lighting conditions, the quality of the camera calibration and the shape of the object. The article presents the results of a simulation of a multi-camera reconstruction system, for the needs of designing indoor and outdoor 3D scanner. The 3D reconstruction system works by simultaneously taking photographs of cameras located around the object. The simulation was created to investigate the optimal distribution of cameras and projectors casting a pattern that increases the number of characteristic points on the surface of the object. The impact of background removal in images on the reconstruction result as well as the texture quality of the object depending on the resolution and distance of the cameras from the object were also investigated. The graphic engine used to create the simulation also allows testing of impact of various conditions. The presented results prove that the parameters of the system structure, such as the placement of cameras, projectors, the selection of patterns projected by the projectors are important and their values can be determined at the stage of system simulation. The acquired results are promising and will be further investigated.

Rivers as surface water in Malaysia are recipients of effluents and wastewater and yet it is important water source for daily uses of some villagers living along the river. Endocrine disruptors such as Bisphenol A (BPA) can be found in river due to continuous discharge into it. The objectives of this research is to find out the occurrence and concentration of BPA in Sungai Langat and also to see how water quality parameters such as temperature, pH, dissolved oxygen (DO ), turbidity, Total Suspended Solid (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and ammonia nitrogen (AN) affecting the concentration of BPA. 12 stations in total including upstream to downstream of Sungai Langat and also tributary of Sungai Langat. The instrument used to find out concentration of BPA is Triple Quadrupole LC/MS. The source of BPA are mainly industrial effluents and also direct domestic discharges. The water quality parameters that will affect concentration of BPA are Ammonia Nitrogen (AN), turbidity, Biochemical Oxygen Demand (BOD), Total Suspended Solid (TSS), and Chemical Oxygen Demand (COD), Dissolved Oxygen (DO). While pH and water temperature are also factors that will affect concentration of BPA but the significance is not shown in the analysis. It can be concluded that u pstream of Sungai Langat has lower concentration of BPA than downstream.

This report is influencing infill density and layer thickness on mechanical strength of Poly-lactic Acid (PLA) material in three-dimensional printing machine. According to use Additive Manufacturing technology in PLA material used Fused Deposition Modeling (FDM) technique. In this project, nine samples are tested for different infill pattern (Zig zag, Triangles & Grid) and different layer thickness (0.2, 0.1 & 0.15) mm by using Taguchi Method. Here we demonstrate an empirical method utilizing a statistical design of experiment technique and standardized mechanical testing which ultimately exposes trends and variable interactions specific to our selected additive manufacturing process. We collect data then converted to stress and strain values in order to construct stress vs. strain diagram and try to use a few basic formulas, mechanical properties such as modulus, yield stress, ultimate tensile stress, and percent elongation were able to be determined for each geometrical infill density and thickness layers. The results for each sample were then compared and made design of experiments (DoE) for research best design and quality. A computer simulation like NX was also done in order to reflect on the predictability of the printed specimen’s performance. The aim of doing this report is how to operate 3D printing and use relevant application such as NX, Cura Software, Weka, Minitab, MATLAB and implementation of tensile strength for our samples.

: The credit cards’ fraud transactions detection is the important problem in machine learning field. To detect the credit cards’ fraud transactions help reduce the significant loss of the credit cards’ holders and the banks. To detect the credit cards’ fraud transactions, data scientists normally employ the un-supervised learning techniques and supervised learning technique. In this paper, we employ the graph p-Laplacian based semi-supervised learning methods combined with the under-sampling technique such as Cluster Centroids to solve the credit cards’ fraud transactions detection problem. Experimental results show that that the graph p-Laplacian semi-supervised learning methods outperform the current state of art graph Laplacian based semi-supervised learning method (p=2).
