Authors: Dos Santos M. J. , Freitas M. M. , Ramos A. J. A. , Almeida Júnior D. S. , Rodrigues L. R. S.
Published: June 2020

The purpose of this manuscript is to establish well posedness as well as the existence of global and exponential attractor for a nonlinear Timoshenko system subject to control terms in the two equations of the system. Since the control terms act on both equations, we will not use the nonphysical relationship known as equal speeds of propagation of waves. A combination involving friction-delay and friction controls will act on the angle of rotation equation, while a nonlinear friction control will act on the transverse motion equation. The result will be established by showing that the system is quasi-stable and by using a relationship involving the size of the friction type controls inserted in the rotation angle equation.
Grafting of iron on amorphous silica surfaces from ab initio calculations
Authors: Gueddida Saber , Badawi Michael , Lebègue Sébastien
Published: June 2020

Iron over silica catalytic systems have attracted considerable attention due to their activity and selectivity in different reactions, for instance, in the hydrodeoxygenation process. Here, the grafting mechanisms of iron under various forms (one atom, two atoms, or a cluster) on silica surfaces are studied using ab initio calculations. Various geometries with different locations of iron on the silica structure have been investigated, and it is found that a strong interaction between iron and the silanol groups takes place, mostly driven by the formation of Fe–O–Si bonds, and in few cases by nearby surface OH groups, creating Fe–OH–Si bonds. For the cluster, we show that the most favorable adsorption mode induces a strong effect on the silica surface accompanied with a large charge transfer, making it very stable and promising for a large panel of applications.
The quantum group SLq⋆(2) and quantum algebra Uq(sl2⋆) based on a new associative multiplication on 2 × 2 matrices
Authors: Aziziheris K. , Fakhri H. , Laheghi S.
Published: June 2020

We present classical groups SL⋆(2) and SU⋆(2) as well as classical Lie algebra sl2⋆(C) associated with a new associative multiplication on 2 × 2 matrices. The idea of the new multiplication is generalized to the action of a 2 × 2 square matrix on a 2 × 1 column one. The coordinate Hopf algebra O(SLq⋆(2)) is introduced as a q-generalization of Hopf algebra O(SL⋆(2)), and it is shown that the coordinate algebra corresponding to the quantum plane Cq2 is a SLq⋆(2)-left-covariant algebra. Furthermore, the quantized universal enveloping algebra Uq(sl2⋆) with the Hopf structure as a dual of O(SLq⋆(2)) is introduced. For each of the Hopf algebras O(SLq⋆(2)) and Uq(sl2⋆), we associate two different real forms with two inequivalent families of *-involutions, with O(SUq⋆(2)) and Uq(su2⋆) as one of the real forms. It is shown that the Hopf algebra pairing is a dual pairing of two Hopf *-algebras O(SUq⋆(2)) and Uq(su2⋆).

Published: June 2020

Recent research on intrinsic magnetic topological insulators (MTIs), MnBi2Te4, sheds new light on the observation of a long-expected high-temperature quantum anomalous Hall effect (QAHE). However, the strong interlayered anti-ferromagnetic (AFM) coupling hinders the practical applications without applying a magnetic field. Thus, how to adjust the magnetism of this compound under zero field is essential. Here, we theoretically and experimentally study the magnetic properties of two new promising intrinsic MTI candidates MnBi4Te7 and MnBi6Te10, formed by intercalating the Bi2Te3 layer into MnBi2Te4. The first-principles calculations reveal that the relative energy between ferromagnetic (FM) and AFM states is greatly reduced by Bi2Te3 intercalations. The calculated energy barriers for the spin flipping process also point out that the metastable FM state is more easily retained by intercalation. Meanwhile, we also experimentally carry out magnetic and transport measurements on these materials. By increasing Bi2Te3 intercalations, the AFM coupling becomes weaker, and an almost fully polarized FM state can be preserved in MnBi6Te10 at low temperatures, which are consistent with our calculations. We believe that the demonstration of the intrinsic MTI preserving zero-field FM state and the in-depth investigation for the mechanism behind pave the way for investigating the high-temperature QAHE and the related physics.
Moon phase and nocturnal activity of native Australian mammals
Authors: Linley G. D. , Pauligk Y. , Marneweck C. , Ritchie E. G.
Published: June 2020

Moon phase and variation in ambient light conditions can influence predator and prey behaviour. Nocturnal predators locate prey visually, and prey may adjust their activity to minimise their predation risk. Understanding how native mammals in Australia respond to varying phases of the moon and cloud cover (light) enhances knowledge of factors affecting species’ survival and inference regarding ecological and population survey data. Over a two-year period within a fenced conservation reserve, in south-eastern Australia, with reintroduced native marsupial predator and prey species (eastern barred bandicoot, southern brown bandicoot, long-nosed potoroo, rufous bettong, Tasmanian pademelon, brush-tailed rock-wallaby, red-necked wallaby, eastern quoll, spotted-tailed quoll, and naturally occurring swamp wallaby, common brushtail possum, common ringtail possum), we conducted monthly spotlight surveys during different moon phases (full, half and new moon). We found an interaction between cloud cover and moon phase, and an interaction of the two depending on the mammal size and class. Increased activity of prey species corresponded with periods of increasing cloud cover. Predators and medium-sized herbivores were more active during times of low illumination. Our findings suggest that moon phase affects the nocturnal activity of mammal species and that, for prey species, there might be trade-offs between predation risk and foraging. Our findings have implications for: ecological survey design and interpretation of results for mammal populations across moon phases, understanding predator and prey behaviour and interactions in natural and modified (artificial lighting) ecosystems, and potential nocturnal niche partitioning of species.
ASY1 acts as a dosage-dependent antagonist of telomere-led recombination and mediates crossover interference in
Arabidopsis
Authors: Lambing Christophe , Kuo Pallas C. , Tock Andrew J. , Topp Stephanie D. , Henderson Ian R.
Published: June 2020

During meiosis, interhomolog recombination produces crossovers and noncrossovers to create genetic diversity. Meiotic recombination frequency varies at multiple scales, with high subtelomeric recombination and suppressed centromeric recombination typical in many eukaryotes. During recombination, sister chromatids are tethered as loops to a polymerized chromosome axis, which, in plants, includes the ASY1 HORMA domain protein and REC8–cohesin complexes. Using chromatin immunoprecipitation, we show an ascending telomere-to-centromere gradient of ASY1 enrichment, which correlates strongly with REC8–cohesin ChIP-seq data. We mapped crossovers genome-wide in the absence of ASY1 and observe that telomere-led recombination becomes dominant. Surprisingly,
asy1/+
heterozygotes also remodel crossovers toward subtelomeric regions at the expense of the pericentromeres. Telomeric recombination increases in
asy1/+
occur in distal regions where ASY1 and REC8 ChIP enrichment are lowest in wild type. In wild type, the majority of crossovers show interference, meaning that they are more widely spaced along the chromosomes than expected by chance. To measure interference, we analyzed double crossover distances, MLH1 foci, and fluorescent pollen tetrads. Interestingly, while crossover interference is normal in
asy1/+
, it is undetectable in
asy1
mutants, indicating that ASY1 is required to mediate crossover interference. Together, this is consistent with ASY1 antagonizing telomere-led recombination and promoting spaced crossover formation along the chromosomes via interference. These findings provide insight into the role of the meiotic axis in patterning recombination frequency within plant genomes.

Authors: Wang Yingjie , Liu Meiyi , Gao Jiali
Published: June 2020

Significance

Enhanced receptor binding by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is believed to contribute to the highly contagious transmission rate of coronavirus disease 2019. An understanding of the structural and energetic details responsible for protein–protein interactions between the host receptor ACE2 and SARS-CoV-2 can be useful to epidemic surveillance, diagnosis, and optimization of neutralizing agents. The present study unravels a delicate balance of specific and nonspecific hydrogen-bonding and hydrophobic networks to help elucidate the similarities and differences in receptor binding by SARS-CoV-2 and SARS-CoV.
Building in language support in a Hong Kong CLIL chemistry classroom
Authors: Tsang Michael Kai-yip
Published: June 2020

Science writing has played a crucial part in science assessments. This paper reports a study in an area that has received little research attention – how science lessons in content and language integrated learning (CLIL) can increase the science knowledge development of English as a foreign language (EFL) students in Hong Kong. The data come from a school-based interventional study in chemistry classrooms, with written data from questionnaires, assessments and teachers’ logs and verbal data from interviews and classroom observations. The effectiveness of the CLIL teaching and learning activities in various chemistry classrooms were compared and evaluated, with a discussion of some implications. The paper concludes that CLIL teaching and learning activities yielded positive learning outcomes among chemistry learners with low English ability.
Aggression in media-sharing websites in the context of Greek political/parliamentary discourse in the years of the economic crisis

Published: June 2020

In the context of the Greek economic crisis during the years 2009–2019, the aim of the present study is to discuss
language aggression and derogatory forms of speech attested in user polylogues commenting on instances of parliamentary discourse
uploaded to computer mediated communication networks. Within the framework of (im)politeness research (Culpeper 2005, 2011; Garcés-Conejos Blitvich 2010a; Haugh 2013; Lorenzo-Dus, et al. 2011; Mitchell and Haugh 2015), we
investigate the correlation between impoliteness and abusive verbal discourse in both domains, i.e. parliamentary sittings and
social media commentary. We explore their potential to establish a common ground in viewing political issues and determining
ideological polarizations. We also attempt a preliminary analysis of swear words and derogatory references to Greek political
personnel and their instrumentalisation for the division of the readership into those who support and those who oppose different
political agendas.
1916
Authors: Bigliazzi Silvia
Published: June 2020

The essay argues that Shakespeare’s Tercentenary in 1916, following the peak of his popularity on the nineteenth-century Italian stages, coincided with a peculiar cultural and political transition in Italy due to Italy’s ‘embarrassing’ entry into the war alongside the Entente in 1915. By proceeding from a discussion of the Italian contributions to Israel Gollancz’s 1916 A Book of Homage to Shakespeare, and their discursive strategies complying, but also competing, with the book’s imperialist design, to an exploration of the 1916 issue of the Florentine literary magazine Il Marzocco devoted to a celebration of Shakespeare, this chapter explores how Shakespeare was ‘narrativised’ into a multi-faceted political icon. It discusses the manners of silencing, but also exposing, his subversive potential in the context of the Tercentenary, exhibiting the manipulative force of memory and forgetfulness at a time of sudden political and cultural changes which reflect a crisis of national identity.
The translator
Authors: Saldanha Gabriela
Published: June 2020

This article proposes that in order to understand the nature of literary translation as an art form, we need to
complement existing approaches drawing on literary, linguistic and sociological theories with insights derived from performance
studies. As a way of exploring what the theorization of translation as performance art could contribute to our understanding of
literary translation, I map four basic tenets of performance as restored behavior (Schechner
1985) to two translators’ (Margaret Jull Costa and Peter Bush) accounts of their practice. The mapping is illustrated
with writings by and interviews with the translators, focusing on four points of contact: the unresolved dialectal tension between
self and other, the deliberate, rehearsed nature of decisions, the need for distance between original and performance/translation,
and the role of the audience.

Published: June 2020

Nanostructured semiconductor, copper sulphide, CuS prepared by a mechanochemical synthesis in a large-scale operation industrial mill was modified by surfactant-assisted milling in a planetary mill. Surface modified CuS with cetrimonium bromide, and sodium dodecyl sulphate surfactants were characterised by particle size distribution and compared to mechanochemically synthesised CuS. X-ray diffraction, Fourier-transform infrared spectroscopy and elemental analysis confirmed the binding of surfactants to the CuS structure. Transmission electron microscopy has revealed that the particles composed of nanocrystallites are embedded in the surfactant matrix. Their optical properties were studied using ultraviolet–visible and photoluminescence spectroscopies. The optical band gap energies were determined to be 1.70 and 1.63 eV for CuS modified with cetrimonium bromide and sodium dodecyl sulphate.

This report describes a supplementary comparison on current ratio at power frequencies. The traveling standard was a high precision current transformer. Frequencies of 50 Hz and 60 Hz were used with a current range between 5 A and 1000 A. Participants belong to SIM, except the national metrology institute of Germany, PTB, that belongs to EURAMET. The pilot institute was UTE, from Uruguay. The measurement results and uncertainties from all national metrology institutes, that have declared CMCs, were in agreement with them. The schedule had long delays due to customs procedures, but had no influence on the results due to the very high stability of the traveling transformer.

Effect of pressure profile on stochasticity of magnetic field in a conventional stellarator
Authors: Suzuki Yasuhiro
Published: June 2020

In this study, the stochastization of the magnetic field in a simplified stellarator, which has a strong magnetic shear in the peripheral region, is studied using a nonlinear 3D equilibrium calculation code, HINT, which calculates the nonlinear resistive steady state using the relaxation method without the assumption of nested flux surfaces. For the finite beta equilibrium, the pressure-induced perturbed field breaks the nested flux surfaces, and the stochastization of the magnetic field appears in the region of the strong magnetic shear. The stochastization penetrates into the plasma core due to the increased beta and the effective plasma confinement degrades; in other words, the effective plasma volume shrinks. The stochastization strongly depends on the profile shape of the plasma pressure. Since the pressure gradient drives the Pfirsch–Schlüter current, the pressure profile affects the stochastization of the magnetic field. In order to understand the equilibrium beta limit due to the stochastization of the magnetic field, the profile shape of the plasma pressure is an important factor.

Magnetic characterization of a thin Co2MnSi/L10–MnGa synthetic antiferromagnetic bilayer prepared by MBE*
Authors: Li Shan , Lu Jun , Mao Si-Wei , Wei Da-Hai , Zhao Jian-Hua
Published: June 2020

A synthetic antiferromagnet based on a thin antiferromagnetically coupled Co2MnSi/MnGa bilayer with Pt capping is proposed in this work. Square magnetic loops measured by anomalous Hall effect reveal that a well perpendicular magnetic anisotropy is obtained in this structure. A very large coercivity of 83 kOe (1 Oe = 79.5775 A⋅m−1) is observed near the magnetic moment compensation point of 270 K, indicating an antiferromagnetic behavior. Moreover, the anomalous Hall signal does not go to zero even at the magnetic compensation point, for which the difficulty in detecting the conventional antiferromagnets can be overcome. By changing the temperature, the polarity of the spin–orbit torque induced switching is changed around the bilayer compensation point. This kind of thin bilayer has potential applications in spin–orbit-related effects, spintronic devices, and racetrack memories.

Published: June 2020

We investigate structural, mechanical, thermodynamic, and thermoelectric properties of vanadium-based XVO3 (X = Na, K, Rb) materials using density functional theory (DFT) based calculations. The structural and thermodynamic stabilities are probed by the tolerance factor (0.98, 1.01, and 1.02) with the negative value of enthalpy of formation. Mechanical properties are analyzed in the form of Born stability criteria, ductile/brittle nature (Poisson and Pugh’s ratios) and anisotropy factor. To explore the electronic transport properties, we study the electrical conductivity, thermal conductivity, Seebeck coefficient and power factor in terms of chemical potential and temperature. High values of Seebeck coefficient at room temperature may find the potential of the studied perovskites in thermo-electrics devices.
Ultra-low thermal conductivity of roughened silicon nanowires: Role of phonon-surface bond order imperfection scattering*
Authors: Yang Heng-Yu , Chen Ya-Li , Zhou Wu-Xing , Xie Guo-Feng , Xu Ning
Published: June 2020

The ultra-low thermal conductivity of roughened silicon nanowires (SiNWs) can not be explained by the classical phonon–surface scattering mechanism. Although there have been several efforts at developing theories of phonon–surface scattering to interpret it, but the underlying reason is still debatable. We consider that the bond order loss and correlative bond hardening on the surface of roughened SiNWs will deeply influence the thermal transport because of their ultra-high surface-to-volume ratio. By combining this mechanism with the phonon Boltzmann transport equation, we explicate that the suppression of high-frequency phonons results in the obvious reduction of thermal conductivity of roughened SiNWs. Moreover, we verify that the roughness amplitude has more remarkable influence on thermal conductivity of SiNWs than the roughness correlation length, and the surface-to-volume ratio is a nearly universal gauge for thermal conductivity of roughened SiNWs.
Transparently manipulating spin–orbit qubit via exact degenerate ground states*
Authors: Hai Kuo , Zhu Wenhua , Chen Qiong , Hai Wenhua
Published: June 2020

By investigating a harmonically confined and periodically driven particle system with spin–orbit coupling (SOC) and a specific controlled parameter, we demonstrate an exactly solvable two-level model with a complete set of spin-motion entangled Schrödinger kitten (or cat) states. In the undriven case, application of a modulation resonance results in the exact stationary states. We show a decoherence-averse effect of SOC and implement a transparent coherent control by exchanging positions of the probability-density wavepackets to create transitions between the different degenerate ground states. The expected energy consisting of quantum and continuous parts is derived, and the energy deviations caused by the exchange operations are much less than the quantum gap. The results could be directly extended to a weakly coupled single-particle chain for transparently encoding spin–orbit qubits via the robust spin-motion entangled degenerate ground states.

Published: June 2020

Single event effects (SEEs) in a 28-nm system-on-chip (SoC) were assessed using heavy ion irradiations, and susceptibilities in different processor configurations with data accessing patterns were investigated. The patterns included the sole processor (SP) and asymmetric multiprocessing (AMP) patterns with static and dynamic data accessing. Single event upset (SEU) cross sections in static accessing can be more than twice as high as those of the dynamic accessing, and processor configuration pattern is not a critical factor for the SEU cross sections. Cross section interval of upset events was evaluated and the soft error rates in aerospace environment were predicted for the SoC. The tests also indicated that ultra-high linear energy transfer (LET) particle can cause exception currents in the 28-nm SoC, and some even are lower than the normal case.

Published: June 2020

The falsification and embezzlement of personal data are still found in several cases in the past year. The reason is personal data in physical form are easily manipulated and difficult to be distinguished from the original. The most detrimental impact is if a person’s personal data is used for credit application fraud in the banking industry. Implementation of blockchain technologies, one of which is Ethereum, allows the use of contracts as a rule that must be fulfilled by the parties involved. All stored transactions are perpetual (cannot be deleted or changed), easy to be audited, transparent, and distributed at each participating node. This study aimed to develop a smart contract for personal data transactions with a case study of credit submission at the Bank. The authors developed a trial application using the prototype method in the process of assessment. Assessment was done by black box testing method in the scope of the lab with 10 credit submission data to be transacted. It is resulting in all credit submission data can be transacted and stored in the smart contract. The interview resulted in an opinion that blockchain technology can be used to store personal data and submit credit submissions at the Bank. The results of the analysis on assessments and interviews conclude that blockchain technology can be used as a medium to store personal data and secure credit applications. For future research, testing transactions can be done on Testnet networks with changing several blocks of data.

E-Report is developed based on the web to make it easier in preparing students’ assessment reports in the form of rating reports, competency achievement reports, and ledgers. Even, many high schools/vocational schools in Bali have not implemented the E-Report. Implementation of cognitive walkthrough techniques, heuristic evaluation, and users’ experience questionnaire in this research aimed to find out the results of evaluating user experience from the aspects of effectiveness, efficiency, user satisfaction, and recommendations for improvement. Effectiveness and efficiency were calculated by Cognitive Walkthrough techniques (CW), user satisfaction by user experience questionnaire techniques (UEQ) and recommendations for improvement, obtained from experts who discuss aspects of usability with Heuristic Evaluation techniques and Cognitive Walkthrough data. Based on the results obtained in terms of users, E-Report has been ineffective and inefficient. While in terms of user satisfaction, respondents were satisfied with Applications E-Report. This is because the effectiveness of a task that has a very large error and failure in one of the features as well as the clarity of results that poor user satisfaction can affect processing time. Therefore, evaluation of user experience based on aspects of usability in the E-Report has not met the criteria for products with good usability. Improvements made on the start page, page values, page value results were done through a photo frame. Therefore, identifying the problems from these three sources can further optimize the usability and improve user experience on E-Report.

Safety and comfort are things that everyone wants to get on a trip. Every tourist who wants a vacation to one of the tourist destinations will prioritize these two things. Leisure in travel is influenced by the availability of supporting facilities. From accommodation, restaurants to facilities provided by tourism actors in each tourism object. One problem is the lack of facilities in attractions such as luggage storage (lockers), many tourists in enjoying tourism objects carrying luggage such as backpacks; groceries to backpacks for tourists are classified as backpackers. Of course this will disrupt the comfort of traveling. In the research conducted, researchers wanted to design a system of goods storage services as a form of supporting industry 4.0 in the tourism environment.

This research was an exploratory study from the perspective of lecturers on how to use computers, internet and multimedia (CIM) in Indonesian Polytechnic Electronic Engineering teaching and assignments. There were seventeen lecturers involved as respondents in this study. Three considerations were taken in choosing respondents, namely the teaching experience, the subject matter, and gender. The analysis used in this research was a descriptive analysis of the quantitative and qualitative data. The results showed that 100% of respondents used Whatsapp application (internet based chat) to communicate with students, 17.65% (three lecturers) always used CIM in teaching, i.e. active group and (again) another 17.65% (three lecturers) never used CIM in teaching, i.e. passive group. The active group consisted of one female lecturer, who had ten to twenty years of teaching experience and she taught theoretical course. Meanwhile, the other two were male lecturers and they taught practical subjects. One male lecturer had more than twenty years of teaching experience and the other lecturer had less than ten years of teaching experience. On the other hand, the passive group consisted of one male lecturer who had more than twenty years of teaching experience and he taught theory courses. The other two were female lecturers, one female lecturer taught theoretical course with more than twenty years of teaching experience and the other female lecturer taught practical course who had less than ten years of teaching experience.

One of the special skills learning outcomes in Mechatronics Study Program referring to fifth level of KKNI is being able to design, analyse, improve design performance, and realize the design parts in the maintenance and repair process, operation, and assembly of automation machines, with proper consideration of occupational safety, health and environmental issues. Fulfilling this learning outcome is not easy. This paper presents learning experiences in Mechatronics Study Program of Politeknik Mekatronika Sanata Dharma in an effort to fulfil it. The effort made is to carry out project-based learning in the form of workshop lectures, called “Mechatronics Workshop”. These workshops held in second to fifth semester, and each project was an integration of all lecture material in that semester and before. The project results from workshop will be used in the next workshop, therefore the project is called a multilevel integrated project. Student assessments are determined by giving a checklist on the rubric of assessments, which include the ability to design, manufacture, operate, assemble, design improvement, and performance, in accordance with predetermined learning outcomes. Until now, the results of this workshop lecture have met the learning outcomes, and show high satisfaction scores, both from the perspective of teachers and students.

In Flipped classroom, the sequence of the learning process is inverted. The activity that is traditionally conducted in classroom is done at home; while the activity that is traditionally completed at home, is done in class. This qualitative research aimed at introducing how the implementation of flipped classroom into an English language class affected the learning experience of pre-service English teachers based on Self-Determination Theory framework. In this study, a flipped classroom was implemented on Classroom Management course. A total of 28 prospective English teachers learned the material from e-book and articles, watched videos, and read their friends’ power point presentation online at home. In-class time was devoted to the presentation of the group in charge, question and answer session, discussion, role play, problem-solving, or project accomplishment. The participants of the study were given open-ended questions to gain insight into their responses of flipped classroom implementation. Through content analysis, finding showed that there were four themes emerged which were in line with Self-Determination Theory framework. Pre-service English teachers responded positively to the three basic psychological needs namely competence, autonomy and relatedness during the flipped classroom. The implication to English language teaching is also discussed in this study.
Content design: e-learning module for study on cultural tourism information systems based on local wisdom

Published: June 2020

Facing the 4.0 industrial revolution, it is necessary to carry out reforms and innovations related to national education. Reforms and innovations in the implementation of components of the education system involve changes in curriculum, graduate competencies and assessments, teacher qualifications, funding, facilities and infrastructure, decentralization and educational autonomy. Bali as a world tourist destination must be maintained and passed on to the younger generation. The younger generation can use information technology to help promote Balinese culture. Bali has a lot of local wisdom that can be implemented in the tourism sector. Therefore to promote those local wisdoms, a module that can be accessed through e-learning is developed to help students develop a cultural tourism package based on local wisdom to be promoted online. The modules developed have been tested by content and media experts, which can be used independently by students. Modules can be accessed online at e-learning and they are ready to use instructions for students so they can work on assignments and projects independently. Modules containing this theory and practice are for making brochures, tour packages, videos, and websites, all of which are connected to promote tourism based on local Balinese wisdom.
Re-skilling vocational education and training practitioners in Indonesia

Published: June 2020

Globalisation, together with the escalating levels of internationalisation of education, is placing emerging and unfamiliar pressures on the Indonesia vocational education and training system. Increasingly, Indonesia, like many other ASEAN nations, is being challenged by the growth of employee mobility and currently, their educational institutions struggle to provide the human resource development frameworks to build a modern skilled and efficient workforce. Recognising this need to meet these urgent demands for a modern skilled and trained workforce, the Indonesian government has focused on the introduction of advanced technical and vocational education through a ‘Revitalisation Program for Vocational Higher Education Institutions’. This program is designed to improve the relevance, engagement and understanding between vocational and higher education institutions with business and industry, but it often calls on international educational support. In this paper, we examine the implications of importing ‘external knowhow’ into the Indonesian vocational education and training sector, placing particular focus on culturally appropriate training models, the growing reliance on ‘external’ models of engagement, and the implications for appropriate and sustainable vocational training models. Central to this re-skilling of the vocational education and training sector, are programs that: address the human resource capability development of the educator workforce; build viable and sustainable links to industry in order to provide seamless workforce needs; explore and examine models for successful industry development; and nurture mutually beneficial ‘strategic partnerships’ both locally and internationally.
Consideration of issues and countermeasures to acquire core human resources through vocational education to improve local information security in Japan
Authors: Okubo H
Published: June 2020

In Japan, information security specialists are concentrated in urban areas, and there is a shortage of these specialists in other regions. The goal of this paper is to propose a concrete vocational education system for adults who will increase the number of cyber security personnel in local areas. It was hypothesized that in order to increase information security personnel in local areas, and it would be effective to re-employ retired self-defense officers with information security skills as information security managers for local governments through vocational education. It was examined previous cases to verify the hypothesis. At first, in order to prove that the information security field has an advantage in re-employment for retired self-defense officers, I investigated the status of ecosystems where US veterans are re-employed as information security employees in private company. Next, in order to prove that the vocational education for the retired self-defense officers is effective, I investigated the case of re-employment in local government disaster prevention relations as a precedent example of the retirement self-defense officers re-employed through the vocational education. Based on the aforementioned situation, measures are proposed to utilize retired self-defense officers with information security skills as information security managers for local governments through vocational education. Implementing appropriate vocational education for re-employment of these officers in the information security field could be potentially effective in reducing the shortage of human resources in this field in local governments and increase the level of information security in local areas.
