The characteristics of concentrator photovoltaic modules based on a 120 × 120 mm Fresnel lens with secondary concentrators in the form of hollow aluminum focons with internal mirror walls are studied. The optimal sizes and configurations of secondary concentrators are determined to increase the efficiency of focusing systems of concentrator modules. The maximum value of the allowable misorientation angle was obtained, equal to ±0.75°, corresponding to a power drop to a level of 90% relative to the maximum power value of the concentrator photovoltaic module at normal beam incidence. For a module with the most efficient focon 40 mm high and side face slope angles of 17°, the maximum efficiency of the module under laboratory conditions was obtained, equal to 35.15%. Under natural conditions, the efficiency value reached 33.8 The results obtained correspond to the level achieved for the best foreign analogues.

The influence of an electric double layer on the surface of nanometer-thick ytterbium films grown on a Si(111) substrate on their adsorption and catalytic properties has been studied. It is shown that charge density waves (Friedel oscillations) generated in such nanofilms by the Si interface cause nonmonotonic changes of the distance in the double layer with increasing thickness. In turn, compression and expansion of the double layer lead to size dependences of the adsorption-catalytic properties of the film surface. In particular, as the film thickness increases, the adsorption character and decomposition rate of ammonia molecules on the ytterbium surface change.

The Implications of Using Digital Technologies in the Management of COVID-19: Comparative Study of Japan and South Korea (Preprint)
Authors: Yang Sou Hee
Published: June 2023

BACKGROUND

Technology can assist in providing effective infectious disease management, but it can also become a source of social injustice and inequality. To control the rapidly increasing SARS-CoV-2 infections and promote effective vaccine administration, both South Korea and Japan have been using several technology-based systems and mobile apps. However, their different approaches to technology use have yielded contrasting social implications.

OBJECTIVE

Through comparative studies of the use of digital technologies for pandemic management and its social implications in Japan and South Korea, this study aimed to discuss whether the active and optimal use of technology for pandemic management can occur without subverting or compromising important social values, such as privacy and equality.

METHODS

This study compared the social implications of Japan’s and South Korea’s contrasting approaches to technology implementation for COVID-19 pandemic management in early 2022.

RESULTS

Digital technologies have been actively and comprehensively used in South Korea, enabling effective COVID-19 management, but have raised serious concerns about privacy and social equality. In Japan, technologies have been more carefully implemented, thereby not causing similar social concerns, but their effectiveness in supporting COVID-19 regulations has been criticized.

CONCLUSIONS

Potential social implications such as equality concerns, the balance between public interest and individual rights, and legal implications must be carefully assessed in conjunction with effective and optimal infectious disease control to achieve sustainable use of digital health technologies for infectious disease management in the future.

G3 had a good correlation with the Montreal Cognitive Assessment Basic (r = .611, P < .001) among 60 older adults.

CONCLUSIONS

As a novel 3-minute game-based cognitive assessment tool, the G3 mini-program holds promises for cognitive disorder screening and home self-assessment.
The Individual is Not the Institution: The Flawed Logic of the New Brunswick Court of Queen’s Bench Decision in Acadian Society of New Brunswick v Right Honourable Prime Minister of Canada
Authors: Peach Ian
Published: June 2023

In 2021, the Acadian Society of New Brunswick brought an application to the New Brunswick Court of Queen’s Bench seeking a declaration that the appointment of a unilingual anglophone as the Lieutenant Governor of New Brunswick was unconstitutional. Specifically, the Acadian Society claimed that the appointment of Brenda Murphy as New Brunswick’s lieutenant governor in 2019 violated the guarantees in the Canadian Charter of Rights and Freedoms of the equal status of English and French in New Brunswick. On April 14, 2022, the Chief Justice of the Court of Queen’s Bench, Tracey deWare, decided that the appointment of Ms Murphy as New Brunswick’s lieutenant governor was, indeed, in violation of the Charter. Yet, despite this conclusion, the Chief Justice also decided that it was appropriate to leave the question of what the implications of this determination should be to the executive branch of the Government of Canada.
A Minimalistic Approach to Severing the British Royal Family from Canada’s Constitution
Authors: Sheaff Tim
Published: June 2023

In a survey conducted prior to the Queen’s passing, 51 percent of respondents affirmed that the country “should not remain a part of the monarchy in coming generations.” While 55 percent of those surveyed supported the country continuing as a constitutional monarchy so long as the Queen reigned, only 34 percent expressed the same once Charles was to become King. Time will tell whether this general apprehension about Charles III will continue, but given the negative public standing of the new King and the monarchy in general, the question is bound to arise: how can the British royal family be removed from Canada’s constitutional architecture?

Insight of PrEP and Testing STI Puzzle
Authors: Rusetiyanti Nurwestu
Published: June 2023

Pre Exposure Prophylaxis (PrEP) is the use of Anti Retroviral (ARV) drugs by HIV-uninfected people to block the acquisition of HIV before exposure to HIV. There are concerns that PrEP introduction and scale up may pose risks, such as sexual behavior change in specific populations, and have an impact on the budget in already constrained health systems. Therefore, public health measures for the prevention of HIV and other STIs need to be enhanced, such as the prioritization of PrEP, coupled with more effective STI screening and treatment. Integration of STI and PrEP programmes can be viewed bi-directionally (not only integrating STI services into PrEP services but also considering STI clients as people also at risk for HIV and therefore potentially eligible for PrEP). This approach fosters synergies and efficiencies from a public health perspective. However, there are many challenges to programmatic integration, including siloed funding streams and programmes, the availability and costs of expanded etiological STI testing, and gaps in capacity and training for STI management. Keywords : PrEP, STI, services

Survival rate of ischemic stroke has been improving which increases long-term disability in consequences.  GBD 2017 shows stroke as the third most common cause of morbidity. Hypertension is the most common risk factor for ischemic stroke incidence and affecting long-term functional outcome. Therefore, hypertension control in ischemic stroke is expected to improve functional outcome and quality of life. Therefore, this study was conducted to know the role of hypertension as risk factor of poor functional outcome in primary ischemic stroke patients. Study was conducted by observational retrospective cohort from May 2018 until April 2019 in 7 hospitals in D.I. Yogyakarta. Functional outcome of primary ischemic stroke patients was assessed by physician at day 30 by using Barthel Index. Bivariate analysis was analyzed by using Chi-Square with 95% CI and p-value <0.05 indicated statistical significance. Based on the study, there were increased risk for having dependent functional outcome in hypertension (RR=1.12, 95% CI=0.74-1.69), diabetes mellitus (RR=1.041, 95% CI=0.71-1.53) but these results were not statistically significant (p>0.05). From the study it can be concluded that hypertension is one of the most common risk factors of stroke but hypertension has no role in predicting functional outcome.  However, hypertension increases risk for having poor functional outcome in ischemic stroke patients.

Published: June 2023

Indonesia, as one of the Global South countries, has responded to digital transformation by launching the policy of the Minister of Communication and Information Technology Number 5 of 2020 concerning the Implementation of Private Electronic Systems (ESO) for the realization of digital sovereignty. The policy reaped negative sentiments from the public. Several articles considered ‘rubber articles’ indicated to weaken human rights in obtaining and conveying information, as stated in Article 28F of the 1945 Constitution. This study aims to understand the narrative of digital sovereignty built by Kominfo in the ESO policy and strategies to strengthen that narrative. The research method uses a qualitative approach to the Narrative Policy Framework (NFP) by collecting reliable online data from the official Kominfo website, online media, and press conference videos. This study was studied using Agency Theory, where the Indonesian people, as the principal, delegate authority to the agent, Kominfo, related to ESO policies. The results of the NPF found economic narration from the Ministry of Communication and Information Technology. This narration contradicts the narrative of ESO’s policy with the goal of its existence, which is the realization of digital sovereignty. This study also underscores the importance of co-regulation with ESO to strengthen the narrative of digital sovereignty.

Published: June 2023

Semakin berkembangnya pasar big data yang digunakan oleh pengguna khususnya Internet of Things (IoT) berbasis kecerdasan buatan telah menarik banyak pihak baik dari industri maupun akademisi. Melalui penggunaan data lokal dari berbagai perangkat IoT, pemberi layanan aplikasi dapat menghasilkan informasi berguna melalui pendekatan machine learning (ML) seperti centralized learning dengan menggunakan cloud server dan local learning pada perangkat IoT langsung. Namun, dengan adanya risiko bocornya privasi pengguna ketika mengirim data lokal ke cloud server dan sumber daya komputasi yang terbatas pada IoT, penggunaan federated learning (FL) dapat menjadi solusi efisien. Pendekatan FL merupakan sebuah pendekatan ML kolaboratif di mana setiap perangkat IoT dapat melakukan proses training secara independen dan kemudian hanya mengirimkan model local kepada cloud server tanpa melakukan data sharing. Secara khusus, penggunaan FL untuk layanan aplikasi pada perangkat IoT tidak hanya memperbaiki kinerja untuk proses training, namun juga dapat melindungi privasi data bagi penggunanya. Penelitian ini berfokus pada perancangan sistem FL dengan privacy-awareness yang dapat digunakan oleh para pengguna perangkat IoT. Dalam hal ini, teknik enkripsi yang berbasis homomorphic encryption untuk mengenkripsi data dari perangkat IoT ketika proses training dari FL dapat diimplementasikan sebagai bentuk perlindungan privasi pengguna IoT dari malicious attackers. Dari penelitian ini, dapat dianalisis perbandingan tingkat akurasi model dari berbagai pendekatan baik tanpa dan dengan teknik enkripsi tersebut.

Authors: Gligorijević Živorad , Kostadinovic Ivana
Published: June 2023

Judging by the number of travellers, tourism underwent a massive expansion during the second half of the 20th century. The expansion that tourism experienced in the second half of the 20th century continued during the 21st century, with the exception of the periods of the 2008 economic crisis, and the current health crisis (COVID-19 pandemic). In accordance with the aforementioned, it can be pointed out that tourism was in constant progression and development until the crisis, that it was ‘the world’s leading industry’, and that its impact on the process of socio-economic development was continuously growing and intensifying. With this in mind, the aim of this paper is to examine the characteristics and dynamics of the growth of international tourism before, during and after the economic crisis of 2008, as well as during the current health crisis (COVID-19 pandemic), based on relevant macroeconomic indicators. The results of the analysis confirm the well-known facts that tourism is not only very sensitive to crises but also that it is a highly flexible sector that adjusts and resumes the growth of traffic very quickly following the end of a crisis.

Published: June 2023

The application of information and communications technologies (ICTs) in all spheres of human activities has a significant impact on the development of each country. A better understanding of the relationship between these phenomena can contribute to the policy of a more balanced and long-term sustainable development on the national level. In this regard, the aim of the paper is to investigate the link between ICT and development profiles, taking the European countries as an example. We use several composite indexes (i.e., the ITU ICT development index, the global competitiveness index [GCI], and the Legatum prosperity index [LPI]) to investigate these countries’ profiles and find a common structure among their respective relationships. We applied the partial least squares regression (PLS-R) model and included a new welfare index – the prosperity index, which integrates all the key dimensions of country development (economic, social, and environmental). Our main finding is that PLS-R models successfully extract important information on common structure vis-à-vis the observed countries’ ICT and development profiles. Certain ICT indicators – namely, Use of ICT and Price of ICT services – can be considered predominant indicators, given their impact on a set of competitiveness and prosperity features within a country. These ICT indicators influence certain competitiveness attributes - Technological readiness, Business sophistication, Institutions, and Innovation, and certain prosperity attributes - Governance, Economic quality, and Personal freedom of the observed countries. These observations may be of great importance, as policy-makers can leverage them when designing the appropriate ICT and development strategies at national level.
COVID-19 AS THE MAGNIFYING GLASS OF CHINA’S FOREIGN POLICY FOR A NEW ERA

Published: June 2023

The COVID-19 pandemic functioned as a catalyst for the already tense relations between the People’s Republic of China and its major Western partners. It also made room for the global span of China’s ‘wolf-war diplomacy’ and ‘mask-diplomacy’ as two simultaneously exposed faces of its foreign policy. This analysis focuses on China’s foreign policy apparatus’ performance during COVID-19, and its effect on China’s domestic and foreign economic and political agendas. Starting from the theoretical point that China’s forceful foreign policy derives from its domestic political dynamism, the analysis shows that such effects were modest. It claims that China’s posting will continue to be resistant to the surroundings’ impact as long as it serves as a good tool for fulfilling domestic stability and security goals.

Published: June 2023

Innovations are present in all fields of human activity. Therefore, they are an indispensable segment of the activities of higher-educational institutions which are going through a very demanding process of development towards future forms of educational, scientific and research work. Higher education activities imply a continuous monitoring of innovations, and their application in the educational process. The aforementioned activities are also related to the academic library, which is an unavoidable factor in the process of carrying out scientific and educational work, and is, unlike the public library, closely related to innovative processes in education and the performance of scientific activities. Using innovative methods and solutions, along with transformational processes, the library must satisfy its users with knowledgeable staff, who are ready to answer questions and meet the challenges of increasingly demanding modern users. For this reason, employees in higher education libraries are obliged to continuously improve their level of education, and to constantly keep up with modern trends, with a particular emphasis on respecting what is prescribed by the principles of the code of ethics and the legal regulations in the field of library work, as well as in the field of activities of higher-educational institutions and the protection of intellectual property. In order for this entire process to be implemented, the management of these institutions must invest all their effort and knowledge into reaching their goals through efficient organisation and a strategy that will lead to a high quality of service and a competitive advantage in this market.

Authors: Kumar Dr. K Kranthi
Published: June 2023

Abstract: Fingerprints and iris scans are two types of biometric identifiers that serve the purpose of identification and authentication. AADHAR is a project initiated by the Government of India that aims to provide a unique identification number to each resident in the country. Due to the complexity associated with storing these biometric identifiers, a compression technique is employed to minimize storage requirements. The study involves an analysis aimed at identifying the storage demands for biometric data in the AADHAR project. Additionally, a proposed approach that utilizes the K-SVD algorithm, based on sparse representation, is presented to considerably decrease the storage space necessary for storing fingerprints and iris scans.

La “proposición Montero” de 1870 en Tarapacá. La primera resistencia tarapaqueña-salitrera a los privilegios monopólicos del centralismo limeño en la periferia
Authors: González Miranda Sergio
Published: June 2023

Tarapacá, en la medida que la industria del salitre comenzaba a tener éxito en el mercado internacional de los fertilizantes a fines de la década de 1860, comenzó a transformarse lentamente en un territorio de interés extrarregional. Las demandas tarapaqueñas por alcanzar la categoría de Provincia Litoral y que se construyera un ferrocarril que uniera sus principales puertos (Pisagua e Iquique) con la pampa salitrera, comenzaban a ser escuchadas. Aparejados a esas demandas llegaron los intereses de agentes tanto públicos como privados a la provincia, los primeros tuvieron su primera expresión con ley que declaró el estanco salitrero en 1873, y los segundos con la presencia de empresarios foráneos a la provincia, tanto extranjeros como peruanos. Entre esos empresarios foráneos estuvo la empresa Montero Hnos. que, gozando de privilegios monopólicos gubernamentales, llegó a construir los ferrocarriles de Tarapacá, pero, adicionalmente, solicitaron a la autoridad provincial privilegios para explotar el caliche existente en las pampas de la provincia bajo una modelo completamente diferente a la industria salitrera existente. Este modelo de localización industrial, que hemos denominado “proposición Montero”, generaría la primera resistencia provincial organizada a los privilegios de una empresa procedente de Lima, impidiendo su aplicación. Movimiento ciudadano que posteriormente se expresaría en la resistencia al estanco salitrero primero y a la expropiación de la industria, después.
