Authors: Tubio Carmen R. , Seoane-Rivero Rubén , Neira Santiago , Benito Vanesa , Zubieta Koldo Gondra , Lanceros-Mendez Senentxu
Published: September 2022

The wide application of fiber-reinforced polymer composite (FRPC) materials has given rise to the problem of their durability and performance over time. These problems are largely associated with their environmental conditions and service procedures, including ultraviolet (UV) irradiation. Here, we propose the production of polyester-based composites with different contents of synthesized Y3Al5O12:Ce3+,Ga (YAG:Ce,Ga) particles to provide sensing abilities towards material degradation. In this regard, the composites were subjected to UV radiation exposure, and its influence on the morphological, mechanical, and optical properties of the materials was investigated. Our findings reveal the self-sensing capabilities of the developed FRPC. The results indicate the potential of the system for the development of highly effective coatings allowing to detect and monitor UV degradation in composite materials for demanding applications.

Published: September 2022

Fused deposition modeling (FDM) is the most economical additive manufacturing (AM) technology available for fabricating complex part geometries. However, the involvement of numerous control process parameters and dimensional instabilities are challenges of FDM. Therefore, this study investigated the effect of 3D printing parameters on dimensional deviations, including the length, width, height, and angle of polylactic acid (PLA) printed parts. The selected printing parameters include layer height, number of perimeters, infill density, infill angle, print speed, nozzle temperature, bed temperature, and print orientation. Three-level definitive screening design (DSD) was used to plan experimental runs. The results revealed that infill density is the most consequential parameter for length and width deviation, while layer height is significant for angle and height deviation. The regression models developed for the four responses are non-linear quadratic. The optimal results are obtained considering the integrated approach of desirability and weighted aggregated sum product assessment (WASPAS). The optimal results include a layer height of 0.1 mm, a total of six perimeters, an infill density of 20%, a fill angle of 90°, a print speed of 70 mm/s, a nozzle temperature of 220 °C, a bed temperature of 70 °C, and a print orientation of 90°. The current study provides a guideline to fabricate assistive devices, such as hand and foot orthoses, that require high dimensional accuracies.

Published: September 2022

Three-component slow-release fungicide formulations with different modes of action of the active ingredients for suppressing potato pathogens were constructed for the first time. The difenoconazole, mefenoxam, prothioconazole, and azoxystrobin fungicides were embedded in the degradable polymer P(3HB)/birch wood flour blend and examined using SEM, IR spectroscopy, X-ray analysis, DTA, and DSC. Results showed that no chemical bonds were established between the components and that they were physical mixtures that had a lower degree of crystallinity compared to the initial P(3HB), which suggested different crystallization kinetics in the mixtures. The degradation behavior of the experimental formulations was investigated in laboratory micro-ecosystems with pre-characterized field soil. The slow-release fungicide formulations were prolonged-action forms with a half-life of at least 50–60 d, enabling gradual and sustained delivery of the active ingredients to plants. All slow-release fungicide formulations had a strong inhibitory effect on the most common and harmful potato pathogens (Phytophthorainfestans, Alternarialongipes, Rhizoctoniasolani, and Fusariumsolani).

Going Back to Fundamentals: Three Marriageable Actions for Thalassemia and Carrier Population Management
Authors: Kim Sehjeong , AlDhaheri Hamda , Kim So-Yeun
Published: September 2022

We investigated the impact of three marriageable actions: normal-to-carrier, carrier-to-normal, and carrier-to-carrier marriages on thalassemia and carrier populations. The well-known strategy is limiting the carrier-to-carrier marriage to reduce the thalassemia population. Thus, the other two marriageable actions were often ignored. Other than a simple explanation of their genetic consequences, their important aspect in the thalassemia inheritance mechanism has never been studied at the population level. Moreover, there is no mathematical model investigating problem of interest for blood disorders at the population level. Hence, we developed a mathematical model to examine the possibility of eradication/reduction of thalassemia and carrier populations through each of the three marriageable actions in the long-term. We conducted computer simulations with the demographic data of the United Arab Emirates in which high thalassemia carrier prevalence is identified. We found that promoting more carrier-to-normal marriage will eventually have the same effects on marriage reconsideration for carrier-carrier couples, contributing to the reduction of the carrier population in the long-term. Interestingly, the normal-to-carrier marriage does not necessarily have a similar effect on thalassemia and carrier populations as that of the carrier-to-normal marriage. Thus, the two marriageable actions should be distinguished and also seriously considered in education and public awareness campaigns for thalassemia.

Authors: Wan Xin , Song Yingjie , Zhou Hua , Shao Mingfei
Published: September 2022

Electrochemical water splitting is one of the effective ways to obtain highly pure hydrogen. However, as one of the two half reactions, oxygen evolution reaction (OER) has a high overpotential, resulting in the low-energy utilization efficiency. Therefore, numerous electrocatalysts have been developed to reduce the energy barrier of OER. Among them, layered double hydroxides (LDHs) are excellent OER electrocatalysts with flexible composition and structure, which have been widely investigated in the past decade. Recent studies have been focusing on the identification of active sites for LDHs during OER process, trying to reveal clear reaction mechanism for designing more efficient LDHs electrocatalysts. Hence, this review tries to discuss the advances in identifying active site of LDHs based OER electrocatalysts for efficient hydrogen generation. We first introduce the effect of structure, composition, and defects to the OER performance of LDHs. Furthermore, main attention is paid on the active sites and mechanisms during OER, especially the coordination structures and catalytic mechanisms of active sites. At the end of this review, we put forward the existing problems and shortcomings in this fields, and propose the corresponding solutions, aiming to further promote the development of outstanding OER electrocatalysts towards efficient hydrogen production.

) space. With CubeSat as the carrier, the deployable Cubot aims to achieve a variety of on-orbit operation tasks including space debris removal and space station on-orbit maintenance, for future on-orbit servicing, assembly, and manufacturing (OSAM). A kinematics modeling method of a space manipulator with passive joints is proposed, and the motion equation of the manipulator is derived. Considered the elastic potential energy stored in the passive joint during deployment, the momentum change of Cubot is simulated and analyzed. As the main forced element, the end effector is analyzed using FEA. Dynamic stress response with respect to the force distribution and the clamping angle is analyzed to evaluate mechanical performances of the end-effector component. Deployment tests are conducted to verify the feasibility of Cubot based on a principled prototype, which aims to provide engineering and practical experience for the development of this field.
From Teachers’ Innovative Practices to Students’ Co-Creation: A Glimpse of the Project “Link Me Up – 1000 Ideias”
Authors: Fernandes Rosina , Amante Susana
Published: September 2022

Higher Education Institutions are, more than ever, open to innovative practices, and nowadays the triple helix of University, Industry and Government is taking place through the implementation of projects such as “Link Me Up – 1000 Ideias”. This project, funded by COMPETE, was created as a network bringing together thirteen Portuguese Polytechnic Institutes to promote entrepreneurship among students, called talents, in academia. In a multidisciplinary approach, a co-creation team of 4-6 students, working together with organisation partners and using teacher’s innovative practices, explore a future-oriented challenge in order to design solutions, ideas and future scenarios, in an 8-week process that aims to empower students to create their own innovative companies or projects and to help them to be prepared for the transition to the world of work, developing soft skills that are required in our competitive society. This project is linked to another, entitled “Learning based on co-creation processes,” funded by POCH, in a partnership with DEMOLA Global, which provides teachers (in this process, they become facilitators) with innovative methodologies that are then operationalised when implementing co-creation challenges. In this study, we aim at presenting the “Link Me Up” project from the point of view of students from the Polytechnic Institute of Viseu and local organisations, by a) reflecting upon the questionnaires applied to students and companies to assess their degree of satisfaction with their participation in the project, identifying key areas enhanced by the experience. Additionally, b) we will look at the reports written by the group of students as they summarise the work developed in partnership with companies throughout eight intensive weeks. We will conclude, not with a retrospective view, although it is important to look at the past to build the present, but with the perspective of a future that is collaborative, reflective, critical and increasingly creative.
Towards a Theory of Motivations and Roles in Business Ecosystems
Authors: Mastropetrou Margaret , Bithas George , Kutsikos Konstadinos
Published: September 2022

Focusing on the role of networking organizational structure, the literature on innovation management has turned towards value co-creation. The need for value co-creation has emerged from the fact that, in order for firms to cater for their customers’ needs, they cannot deliver on their own as single entities, but rather participate in business ecosystems. Ecosystems are a fundamental occurrence of the academic literature, as well as the managerial world. In order to gain insight to the operations of ecosystems, a systematic literature was carried out. The research question concerned the motivations that drive participants to join a business ecosystem. Several frameworks were explored with a focus on the roles that participants might fill and their specific attributes. The findings suggest linking the stakeholders’ motivations to specific roles’ attributes, thus leading to the filling of a certain role. The outcomes are then reflected in the luxury goods industry, which is one of the richest and unmanageable sectors and bears the characteristics of an ecosystem. The contribution of this research is fundamental for the ecosystems operations, as the exploration of stakeholders’ motivations is essential for the sustainability of the ecosystem from a managerial perspective.

Published: September 2022

This research aims to analyze entrepreneurship worldwide through the dimensions and pillars of the entrepreneurship ecosystem of each country, identifying the contribution and patterns of behavior and correlation within the entrepreneurship ecosystem. This analysis intends to show the main actions that countries have carried out in support of entrepreneurship and entrepreneurs. The tool used to analyze is machine learning, where various algorithms are applied. The evidence shows that the most relevant pillars in the entrepreneurial ecosystem are I. Opportunity Startup, II. Technology Absorption, III. Risk Acceptance, IV. Risk Capital and V. Process Innovation. The pillars that best correlate are I. Competition and Opportunity Startup, II. Opportunity Startup, and Risk Acceptance, III. Opportunity Startup and Technology Absorption, IV. Cultural Support and Opportunity Startup, and V. Opportunity Startup and Risk Capital. The present work aims to provide knowledge to decision-makers in both the public and private sectors to channel public policies that support entrepreneurs in this time of crisis and promote the generation and strengthening of entrepreneurial activity. Although there are still no reliable GEI data for the years 2020 to 2022, the economic crisis generated by the stagnation in the development of the countries has reduced support for entrepreneurs, which in many cases can be a key factor for the rescue of the most disadvantaged countries.
Lean Startup Practices: Operationalizing the Technological Business Planning Process in an Academic Environment
Authors: Reis Luciana , Fernandes June , Araujo Marbia , Beaulieu Martin
Published: September 2022

The generation of innovation in the academic environment involves the development of technology/product, technological transfer and business, which together make up the Technological Business Planning Process (TBPP). This process can be divided into three stages: world of technology (initial stage), world of transition from technology to product and business (intermediate stage), and world of business (final stage). In this context, there is the Lean Startup (LS) methodology, which comprises a set of potential practices to facilitate the operationalization of these stages of development. However, the existing literature is incipient and lacks guidance on the LS practices with the greatest potential to contribute to each of these stages, which constitutes a theoretical gap. Thus, this research aims to identify the LS practices most used by researchers-entrepreneurs in the different stages of the Technological Business Planning Process. The methodological approach used was the case study in an important Brazilian public university. In this context, nine innovation projects in the process of generating technological business were analyzed. The results show four main contributions: i) the practices contributed mainly to the intermediate phase of the TBPP; ii) BMC and MVP were considered the most important practices to operationalize TBPP; iii) the LS practices contributed significantly to the knowledge management between team projects; and iv) the combined implementation of the practices highlighted the benefits for TBPP. This study contributes to technology innovation management in the academic environment and provides some gaps that can be developed in future works in technological projects context.
Collaborate or Perish: A Conceptual Framework for Banks and FinTechs Partnerships
Authors: Faes Alessandro , Gunnella Vito , Giorgino Marco
Published: September 2022

In the Open Finance framework, collaboration of traditional incumbents (i.e., banks) with start-ups (i.e., FinTechs) is crucial for success. However, despite the frequency and relevance of such partnerships in the financial system, research in this field is rather limited, as most works address alliances regardless of the field of application. The limited number of publications related to finance shed light primarily on the motivations promoting interaction among banks and FinTech start-ups, overlooking additional aspects and players. Therefore, the aim of this work is to build a comprehensive framework allowing to properly frame alliances in the financial industry. Focusing on the Italian context, 90 public partnerships were analysed through document analysis of press releases. It emerges that the majority of the alliances do not involve investments in equity and attest strong participation and commitment of FinTech start-ups. On top of common knowledge, we uncovered other relevant variables to consider in this field when analysing each partnership: its direction, which depends on whether the relation resembles more an operative agreement or an industrial one; its field of interest, which details what the collaboration is about; and its addressees, identifying the targets of these alliances. These dimensions, along with the other ones in a comprehensive framework, will contribute to the enrichment of the literature, closing a relevant gap, and serve as a guide for practitioners in addressing these partnerships.

The Influence Factors of China’s Cross-border E-commerce Export Trade Using Gravity Model
Authors:   Korea Trade Research Association, Han Jing , Lee Taehee
Published: September 2022

Purpose - This study examines the influencing factors of China’s cross-border e-commerce exports in the context of the current situation and trends of China’s cross-border e-commerce development. Through an improved trade gravity model, it provides more in-depth research and constructive opinions on the development of cross-border e-commerce in China. In this paper, factors such as consumption gap, volume of trade frictions, number of tourists, Internet usage and trade openness are added to the formula of the traditional trade gravity model in the improved trade gravity model to examine the influencing factors on China’s cross-border e-commerce exports.
Design/methodology - According to the empirical analysis, China’s cross-border e-commerce exports to ten countries are used as dependent variables, and consumption gap, trade friction volume, trade distance, trade openness and number of Internet users are taken as independent variables. Regression analysis is conducted through a modified gravity model to test whether the hypotheses hold.
Findings - The analysis shows that the hypothesis that China’s cross-border e-commerce exports are influenced by trade openness, trade distance, consumption gap between trade parties, and the number of Internet users in the importing country is supported by these four hypotheses, but not all independent variables have an impact on them. Specifically, the number of travelers, trade frictions do not have an impact on China’s cross-border e-commerce. That is to say, trade friction between China and the United States and political issues such as China-India and China-Japan territorial disputes that emerged before do not affect the development of cross-border e-commerce in China.
Originality/value - The analysis shows that the factors influencing China’s cross-border e-commerce exports are the trade openness of the importing country, the trade distance, the number of Internet users in the importing country, and the consumption gap between the two sides of the trade. The trade openness and the number of Internet users positively contribute to China’s cross-border e-commerce, while the consumption gap and trade distance are negatively related to them. And the analysis found that the Sino-US trade war and the Sino-Indian territorial disputes and other trade frictions to China’s cross-border e-commerce exports did not have a substantial impact.

Published: September 2022

Optical phased arrays (OPAs) have received considerable attention as solid-state beam scanners. However, conventional OPAs that actively control the phase difference between arrays are characterized by excessive power consumption for high-precision beam emission. In this study, we fabricated an OPA comprising Bragg grating and arrayed waveguide grating (AWG). Multi-mode waveguide is used in AWG to reduce the effect of manufacturing error. This device realizes wide and high-resolution two-dimensional beam steering only by sweeping wavelength. FWHM of the emitted beam is 0.534° × 2.27°, and the steering range is 43.9° × 13.5° with 1/64 of the power consumption of conventional OPA.

Uji Akurasi Grid-Edge-Depth Map Pada Purwarupa Alat Bantu Melihat Menggunakan Kamera Stereo
Authors: Rahmani Budi
Published: September 2022

The Grid-Edge-Depth Map (GED-map) algorithm can measure objects with distances from 64 cm to 500 cm and has been tested on a wheeled robot to help it avoid obstacles in the experimental environment. This study examines the accuracy of the GED-map that can be used to help people with visual impairments. The research was conducted by modifying a stereo camera into a device that can be used by humans such as a helmet and processed by a laptop. The test was carried out with three scenarios that required the user to stand at a distance of 100 cm, 125 cm and 150 cm from a table, chair, or wall with 15 tests in each scenario. The results of the distance measurement by the system are then computed based on the angle of the installed stereo camera and compared the results with the real distance. The test results show an average accuracy of 94.86% with 3 experimental scenarios, which means that this tool is feasible to implement.

Abstrak. Algoritme Grid-Edge-Depth Map (GED-map) dapat mengukur objek dengan jarak antara 64 cm sampai dengan 500 cm dan telah diuji pada robot beroda untuk membantunya menghindari halangan yang ada di lingkungan percobaan. Penelitian ini menguji akurasi GED-map yang dapat dimanfaatkan untuk membantu para penyandang disabilitas penglihatan. Penelitian dilakukan dengan memodifikasi kamera stereo menjadi perangkat yang bisa digunakan oleh manusia seperti helm dan diproses oleh sebuah laptop. Pengujian dilakukan dengan tiga skenario yang menyaratkan pengguna alat untuk berdiri pada jarak 100 cm, 125 cm dan 150 cm terhadap meja, kursi, maupun tembok dengan 15 kali pengujian pada setiap skenarionya. Hasil pengukuran jarak oleh sistem kemudian dikomputasi berdasarkan sudut kamera stereo yang terpasang dan dibandingkan hasilnya terhadap jarak riil. Hasil pengujian menunjukkan rerata akurasi sebesar 94,86% dengan 3 skenario percobaan, yang artinya alat ini layak untuk diimplementasikan. Hanya saja penelitian dan penyempurnaan perlu dilakukan untuk mengurangi ukuran komputer pemroses pengukuran jarak yang sementara ini masih menggunakan laptop.

In the field of unsupervised feature selection, sparse principal component analysis (SPCA) methods have attracted more and more attention recently. Compared to spectral-based methods, SPCA methods don’t rely on the construction of similarity matrix and show better feature selection ability on real-world data. The original SPCA formulates a nonconvex optimization problem. And existing convex SPCA methods reformulate SPCA as a convex model by regarding reconstruction matrix as optimization variable. However, they are lack of constraints equivalent to the orthogonality restriction in SPCA, leading to larger solution space. In this paper,  it’s proved that the optimal solution to a convex SPCA model falls onto the PSD cone. A new convex SPCA model with PSD constraint is then proposed. Further, a two-step fast optimization algorithm is presented to solve the proposed model. Firstly, adopt the derivative of objective function to obtain the unconstrained solution. Secondly, project the solution onto the PSD cone.The convergence of the  proposed optimization algorithm is studied. With PSD projection, the proposed method takes less number of iterations and running  time than other convex SPCA methods and has stronger feature selection ability. Experiments on both synthetic and real-world datasets demonstrate the effectiveness and efficiency of the proposed method.

Antibiotik profilaksis adalah antibiotik yang diberikan sebelum, saat dan hingga 24 jam pasca operasi pada kasus yang secara klinis tidak adanya tanda-tanda infeksi, namun pemberian antibiotik profilaksis bertujuan untuk mencegah terjadinya infeksi luka operasi, termasuk pada bedah sesar. Tujuan dari penelitian ini adalah untuk melihat rasionalitas penggunaan antibiotik  profilaksis  pada  bedah  sesar  di  RS PMC Pekanbaru. Jenis  penelitian  ini  adalah  penelitian kualitatif dan data yang diperoleh dari rekam medik secara retrospektif, dengan tehnik purposive sampling terhadap 69 rekam medik yang memenuhi kriteria inklusi. Hasil penelitian menunjukkan bahwa penggunaan antibiotik profilaksis pada bedah sesar 66,67 % rasional dan 33,33% tidak rasional. Rasionalitas yang diukur yaitu tepat indikasi (100%), tepat obat (100%), tepat pasien (100%), tepat regimen (tepat dosis (95,61%), tepat frekuensi (79,82%), tepat lama pemberian (100%), tepat cara pemberian (100%) yang diberikan secara intravena), dan waspada efek samping (100%)

Objective: To determine the X-ray, ultrasound, and epidemiological profile of the victims of the attacks of March and April 2019 received at the Mopti hospital. Materials and Methods: This was a cross-sectional study of the victims of the armed attacks of March and April 2019 received at Mopti hospital. The study included all stroke victims who had an x-ray or ultrasound during this time. The variables were the socio-demographic profile, the etiological mechanism, the imaging means and their results. Data analysis was done with SPSS version 25 and Excel 2016 software. Results: The most common age group was 15-29 years old at 35.4%. Men predominated with 66.7%. Civilians were more affected, 83.3%. Firearms accounted for 93.8% of the etiologies. The x-ray was no longer performed, ie 66.7%. The lower limbs were more affected with 31.8%. Fractures of the limbs and the presence of bullets were anomalies most frequent with 25% each one. Conclusion: The majority of the injured were predominantly young and male civilians. Firearms were the most common etiology with predominant involvement in the lower extremities. Radiography was the most used imaging method, and the most common abnormalities were fractures and the presence of ballistic fragments. Gastrointestinal perforation was the most suspected lesion on ultrasound.
The Use of Pronouns in Diplomatic Discourse: An Appraisal of Speeches of some Cameroonian Diplomats
Authors: Temesas Nelson Akeh
Published: September 2022

This paper is aimed at investigating the use of pronouns, specifically the use of personal pronouns in diplomatic discourse made by some Cameroonian diplomats. Diplomacy is a tool for international communication and negotiations, and researchers have shown significant interest in it. The main emphasis here is the use of first personal pronouns ‘I’ and ‘we’ as persuasive methods of communicating to their audience, and diplomatic ideas through the tactical use of the inclusion and exclusion of their audience. There is the use of ‘self’ and ‘group’ participation in their productions. Using personal pronouns, the diplomats’ intentions are identified and also help in the construction of their image. The speeches were selected from the official website of Cameroonian Ministry of External Relation. Critical Discourse Analysis was adopted in order to investigate in what context the personal pronouns (I and we) were used in speeches of two Cameroonian ministers of external relations: Pierre Moukoko Mbonjo and Lejuene Mbella Mbella. The findings show that the occurrences of personal pronouns ‘I’ and ‘we’ in the speeches of both speakers differ slightly, particularly in specific contexts of use. They tend to use more of the ‘we’ pronoun than the ‘I’ in their production. This implies that these pronouns are used differently to achieve different results. They are used to reveal the diplomat’s attitude, motivation, social status and trustworthiness as well as paint a positive image of his country.

The main concern in this study is the low learning motivation of primary school children in Rejomulyo Village, which is brought on by the repetitive nature of the curriculum and the dearth of educators with a range of teaching styles. Offering incentives and icebreakers during lessons is one technique to enhance students' motivation to study. The goal of this study was to investigate whether rewarding and ice-breaking had any impact on their motivation to learn in Rejomulyo Village's public elementary school students, Lampung, Indonesia. This study was conducted in a quasi-experimental manner. A questionnaire and documentation methods were used in the data collection process. A t- test analysis was the method of data analysis employed in this study (independent sample t-test). The test's calculations reveal a strong impact of rewards and ice-breaking on the motivation to learn of Rejomulyo Village's elementary school students.
