Japan’s Quiet Power: The Case of Tokyo’s Vaccine Diplomacy to Southeast Asia
Authors: Dang Bui Hai , Glenn John
Published: July 2022

Amid the COVID-19 pandemic, Japan’s vaccine diplomacy in Southeast Asia has gained much traction as regional countries are wrestling with a dual challenge, i.e., navigating the pandemic and seeking economic recovery and growth. Japan’s donation of coronavirus vaccine shots to Southeast Asian countries confronting this severe pandemic is one expression of Tokyo’s strategic approach towards the region: helping regional countries in need and buttressing its status as a responsible stakeholder. What should deserve attention is that Tokyo has sought a more robust status with its niche diplomacy, the signature characteristic of middle powers, while keeping a low profile in its support for regional countries. The paper argues that as Japan is becoming more committed to the Indo-Pacific region in general and Southeast Asia specifically, Tokyo’s niche diplomacy of vaccine donations has sought to win the hearts and minds of regional countries. The non-traditional approach can foster Japan’s status in Southeast Asia and widen its maneuvering space amid China’s growing assertiveness. Japan’s diplomatic statecraft portrayed via Tokyo’s vaccine diplomacy in Southeast Asia may provide emerging middle powers with valuable lessons on strengthening their influence.

The Purpose of Ratiocination and its Impact on Text Construct from the Viewpoint of the Author of Adwa' Al-Bayan fi Idah Al-Qur'an bil Qur’an: A Jurisprudential-Syntactic Study
Authors: Abdallahi Tar , Alhourani Mohammad Issa , Haswa Maher
Published: July 2022

The present research investigates an important problem in the human history in general and in the legislative history in particular: ratiocination and its purpose in text construct. Ratiocination is a to-convince tool used to interpret religious or social phenomena. In other words, it helps the reader to become hopeful and confident, where the more he perceives the relationships in a text (i.e. causes and effects, and precedents and results), the abler he will be to interact with an epistle. Accordingly, the Islamic legislation, while considering targets’ circumstances, have ratiocinated many of its judgements. The Qur’an is the primary source of the holy Sharia and there are clear-cut occasions where it ratiocinated the judgements to convince the readers. In this research, we investigate the purpose of ratiocination and its role in and impact on text construct from the viewpoint of a jurist-syntactician, given that this person has a deep understanding of the analysis and ratiocination of the Qur’anic provisions. We aim to achieve the purpose of the study by shedding light on the interpretation of this commentator from the Qur’an, in an attempt to uncover the methodological tools that he relied on in ratiocinating the text.

Authors: Dos Santos Luis Miguel
Published: July 2022

On 24th May 2019, the same-sex marriage law took effect, which allowed same-sex couples to marry in Taiwan. About two years after the same-sex marriage law took effect in the community, only a few studies focused on the stress, challenges, discrimination, and sense-making processes of sexual minorities in Taiwan, particularly in the rural communities. Based on the social stigma theory and case study methodology, the researcher collected qualitative data from 16 gay university students who are currently enrolled at one of the Taiwanese universities in rural communities. The results indicated that support of the university administrators, support in the classroom environments, and support in dormitories and roommates were the main findings. The results of this study would fill the research and practical gaps in the fields of same-sex marriage, LGBT rights, and sexual minorities, for the government leaders, non-profit organisations, school administrators, and scholars in the Taiwanese environment.

This study aimed to reveal the role of parental authority in social performance and the regulation of emotions and their relationship to temperament among first-grade students in private schools in Amman-Jordan. A sample of 939 students (males and females) of private schools in Amman was selected through stratified random sampling. The study depends on a correlation descriptive approach and used the parenting practices scale (Alabama Parenting Questionnaire (APQ), the Emotion Regulation Scale, Temperament scale, and the children’s behavior questionnaires (CBQ) to collect data. The means, standard deviation (SD), Pearson’s correlation coefficient and (Z) test were used as statistical methods for data analysis. The results showed that the level of parenting practices scored a medium level, with a mean of (2.90), the emotion regulation scored a medium level, with a mean of (2.99), while the level of temperament scored a high level, with a mean of (4.86) of the total score. The results also showed the existence of a positive, statistically significant relationship at (α = 0.05) between parenting practices and the regulation of emotions, and there was no statistically significant difference at (α = 0.05) in the strength of the relationship due to the effect of the temperament pattern of the students between the regulation of emotions on the one hand and each of the participation, positivity, control, and punishment. Yet, there was a statistically significant difference (α=0.05) in the strength of the relationship due to the effect of the students' temperament level between emotion regulation and control in favor of low temperament.

Authors: Raheel Mohamed Faraj Saleh , Snoubar Yaser
Published: July 2022

Exposure to the physiological, social, and psychological situations of those relocated from Tawergha is a relatively new issue in the study of Libyan forced migration. This inquiry aims to learn more about the social, psychological, and health situations of the people who have been displaced from Tawergha. Residents of two large camps that housed the Tawergha refugees were given a questionnaire. There were 435 displaced people in this research. The findings revealed substantial discrepancies between various characteristics (economic challenges, security situation, living in a disease-spreading environment, mingling with people) and the displaced people's health and psychological problems. The variable of attack exposure only affected the displaced's psychological difficulties. Also, at the 0.05 significance level, other factors such as a lack of housing, the absence of a family member, having adequate food, feeling rejected, movement constraints, and loneliness do not affect psychological difficulties and health conditions. In light of these findings, the study recommends implementing social measures to protect Libya's displaced people. In addition to the need for psychological support programs and the activation of social work for professional assistance with displacement issues, there is also a need for professional help with displacement concerns.

Authors: Cao Hao Thi
Published: July 2022

Cultural integration in foreign language teaching is one of the ways to help learners develop language competence. In foreign language teaching, there have been many successful models of cultural integration. Vietnamese is also a foreign language of interest in some countries. In Vietnam, a cultural integration model in teaching Vietnamese to foreigners has been initially implemented with good results. The program was based on a number of culturally integrated teaching models to help foreigners learn Vietnamese effectively, including such elements as cultural experience (learning to sing folk songs and taking part in plays), and using literary texts (songs, proverbs). The purpose of this article is to report on a study of the effectiveness of this cultural integration program teaching Vietnamese to overseas students at the Thai Nguyen University of Education. The study involved scrutiny of documents, curricula and teaching methods, along with a survey of international students’ perceptions of three particular aspects of the program focused on cultural integration. The study also sought to gauge whether the Vietnamese language ability of the international student learners had been improved by engagement in the new program in comparison with student performance from the previous year. While such improvement was evident, the study offers suggestions for further improvement of the program.

Authors: Alnaim Fahad Ahmad
Published: July 2022

Gifted students with Attention Deficit Hyperactivity Disorder (gifted/ADHD) show complex characteristics, which lead some schools in Saudi Arabia to refer them to gifted programs. Some other schools refer them to learning difficulties (LD) programs due to the spread of LD programs in contrast to the lack of ADHD ones, the overlap of some characteristics between LD and ADHD, and their joint occurrence in a large proportion of students. Thus, this study seeks to explore teachers’ perspectives of the reality, challenges and prospects of educational services provided for gifted/ADHD in gifted and LD programs. The participants in the study were 108 teachers, in addition to three directors of the departments of special and gifted education. The mixed methods approach was used which includes a questionnaire for the teachers and semi-open interviews with the directors of the departments. Results showed inadequacy of educational services provided to gifted/ADHD which due to the absence of the educational system that it focuses on their exceptional duality. In addition, the results highlighted challenges include weak social awareness of the characteristics of these students, and educational environment, with the lack of necessary scales and adequate qualification for teachers. The results also confirmed, in terms of prospects, the importance of creating a competent authority to care for these students and others who fall into the twice-exceptional. Finally, the results showed that there were no statistically significant differences in professions nor in the region. In light of the results of the study, some recommendations were highlighted.

Turkey - Africa Institutional Cooperation: Strategic Impacts, Significance and Challenges
Authors: Kyirewiah Francis Kwesi , Bilate Getachew Toma
Published: July 2022

The development of economic cooperation, diplomacy, and political relations between Turkey and Africa in the past years is attracting many courtesies. Current trends show an increasing engagement and relations between African nations and Turkey which seems to exhibit consistent growth since Ankara declared 2005 as ‘the year of Africa.’ This study examines the institutional cooperation, strategic impacts, their significance, and challenges to Turkey-Africa relations The argument is given based on the fact that Turkish ideologically distanced itself from the global South during and after the Cold War period. However, the fast-paced collaboration in the 21st century signifies a partial revision in its foreign policy orientations towards Africa. In the background of this revisionist orientation, Turkey considers Africa as a way of not only reframing its relations with its nations but also strengthening cooperation with African political and economic institutions. Despite their historical ties, both Africa and Turkey’s cooperation have not transcended to a comprehensive and strategic level. This study finding indicates that Turkey’s growing involvement in Africa reflects its need to establish new markets for its manufactured goods, and its defense and armaments industry and present itself as a relevant regional and global actor different from traditional western players on the continent. What is more, African leaders also seek to attract Turkish Foreign Direct Investment, diversify economic and political partners to reduce dependency, and fuel their state-building projects. Currently, the political cooperation between Turkey and Africa seems to be in good health. Turkey’s endeavors in the field of development cooperation demonstrate its dedication to the efforts aimed at poverty eradication and development for a better future for all. However, both Turkey-Africa’s institutional cooperation is less effective due to a lack of commitments from both sides, inadequate technological resources, political dynamics, and instabilities in some parts of Africa.

Published: July 2022

Nigerian Anacarddiacea family was investigated in this study on the account of their inherent structures with a view to bringing to the fore those features that could facilitate identification towards proper utilization based on wood quality. Mature wood species of Lannea grandis, Lannea welwitchii, Mangifera indica, Nothospondis staudtia, Pseudospondias microcarpa, Sclerocarya burrea, Sorindeia trimeris, Spondias mangifera, Spondias mombin and Trichoscypha acuminate were got from the Forestry Research Institute of Nigeria herbaratum, in Ibadan. Wood samples from the wood species were sectioned into cross sectional, tangential and radial sections of about 20μm thick using a Reichert sliding microtome. Photomicrographs were taken using a digital camera mounted on a Reichert light microscope at 40 ×. The results showed that vessels were large in all the wood species except in Lannea species, Sclerocarya burrea, Nothospondis staudtia and Trichoscypha acuminata. Body ray cells were procumbent with one row of upright and/or square marginal cells in all the wood species, but could be up to four rows in Sorindeia trimeris. Generally, septate fibres, silica,crystals and gum were observed in almost all the wood species, yet, fibre pits in Mangifera indica, Nothospondis staudtia, Pseudospondias microcarpa, Sclerocarya burrea, Spondias mombin, and L. grandis were not as bordered as they were in L. acida, L. welwitchii, Sorindeia trimeris, Spondias mangifera, and Trichoscypha acuminata. S..mombin and S. mangifera can be separated on this account. It also appears that rays were storied only in Sorindeia trimeris and L. grandis. In the aspect of wood utilization, some were expected to possess fine texture, lustrous patterns and also regions of failures as a result of high rays.

Published: July 2022

Various machine learning technologies and artificial intelligence techniques were applied on different applications of dentistry. Caries detection in orthodontics is a very much needed process. Computer-aided diagnosis (CAD) method is used to detect caries in dental radiographs. The feature extraction and classification are involved in the process of caries detection in dental images. In the 2D images the geometric feature extraction methods are applied and the features are extracted and then applied to machine learning algorithms for classification. Different feature extraction techniques can also be combined and then the fused features can be used for classification. Different classifiers support vector machine (SVM), deep learning, decision tree classifier (DT), Naïve Bayes (NB) classifier, k-nearest neighbor classifier (KNN) and random forest (RF) classifier can be used for the classification process. The proposed MDP extracts both intensity and edge information and creates the feature vector that increases the classification accuracy during caries detection.

Fan-Shaped Flooding in Wireless Sensor Networks
Authors: Kim EunHwa
Published: July 2022

In a wireless sensor network, data flows in two main directions. There are flooding that transfers data from the sink node to the entire node and routing that transfers data sensed by each sensor node to the sink node. Transferring data from the sink node of the wireless sensor network to the entire sensor node is called flooding. In an energy-constrained environment, a more efficient method has been developed, because the most basic flooding technique contains a lot of data redundancy. In this paper, the combination of the distance-based approach and the neighboring node information method is proposed as a more energy-efficient method. Flood data can be transmitted by adjusting the angle of the transmission line within the transmission radius to the shape of a fan and limiting the distance within the communication radius. The redundancy and connectivity of data were compared and examined according to angle and distance values, and the experiment proved that the proposed method can provide connectivity to the entire sensor node while reducing data redundancy. It was confirmed that the optimal angle and distance could change according to the density and communication radius of the network. Additional research will be needed, such as a method that can dynamically calculate the optimal angle and distance while taking into account factors like network density and communication radius.
Design of an Integrated Cryptographic SoC Architecture for Resource-Constrained Devices
Authors: Kanda Guard , Ryoo Kwangki
Published: July 2022

One of the active research areas in recent years that has seen researchers from numerous related fields converging and sharing ideas and developing feasible solutions is the area of hardware security. The hardware security discipline deals with the protection from vulnerabilities by way of physical devices such as hardware firewalls or hardware security modules rather than installed software programs. These hardware security modules use physical security measures, logical security controls, and strong encryption to protect sensitive data that is in transit, in use, or stored from unauthorized interferences. Without mechanisms to circumvent the ever-evolving attacking strategies on hardware devices and the data that they process or store, billions of dollars will always be lost to attackers who ply their trade by targeting such vulnerable devices. This paper, therefore, proposes an integrated cryptographic SoC architecture solution to this menace. The proposed architecture provides security by way of key exchange, management, and encryption. The proposed architecture is based on a True Random Number generator core that generates secret keys that are used in Elliptic Curve Diffie-Hellman Key Exchange to perform elliptic curve scalar multiplication to obtain public and shared keys after the exchange of the public keys. The proposed architecture further relies on a Key Derivation Function based on the CubeHash algorithm to obtain Derived Keys that provide the needed security using the ChaCha20_Poly1305 Authenticated Encryption with Associated (AEAD) Data Core. The proposed Integrated SoC architecture is interconnected by AMBA AHB-APB on-chip bus and the system is scheduled and controlled using the PicoRV32 opensource RISC-V processor. The proposed architecture is tested and verified on the Virtex-4 FPGA board using a custom-designed GUI desktop application.
A Novel Medical Image Segmentation Model with Domain Generalization Approach
Authors: Gomathi R , Selvakumaran S
Published: July 2022

In deep learning-based computing vision for image processing, image segmentation is a prominent issue. There is promising generalisation performance in the medical image segmentation sector for approaches using domain generalisation (DG). Single domain generalisation (SDG) is a more difficult problem than conventional generalisation (DG), which requires numerous source domains to be accessible during network training, as opposed to conventional generalisation (DG). Color medical images may be incorrectly segmented because of the augmentation of the full image in order to increase model generalisation capacity. An arbitrary illumination SDG model for improving generalisation power for colour image segmentation approach for medical images through synthesizing random radiance charts is presented as a first solution to this challenge. Color medical images may be decomposed into reflectivity and illumination maps using retinex-based neural networks (ID-Nets). In order to provide medical colour images under various lighting situations, illumination randomization is used to enhance illumination maps. A new metric, TGCI, called the transfer gradient consistency index was devised to quantify the performance of the breakdown of retinal images by simulating physical lighting. Two of the existing retinal image segmentation tasks are tested extensively in order to assess our suggested system. According to the Dice coefficient, our framework surpasses previous SDGs and image improvement algorithms, outperforming the best SDGs by up to 1.7 per cent.

Electricity use and its access are correlated in the economic development of any country. Economically, electricity cannot be stored, and for stability of an electrical network a balance between generation and consumption is necessary. Electricity demand depends on various factors like temperature, everyday activities, time of day, days of the week days/Holidays. These parameters have led to price volatility and huge spikes in electricity prices. The research work proposes a short term Load prediction Model for LT2 (residential consumers), LT3 (Commercial Consumers) of Karnataka State Electricity Board using Cascaded Feed Forward Neural Network (CFNN). MATLAB software is utilized to design and test the forecasting model for predicting the power consumption. Furthermore, a shallow feed forward neural network-based prediction model is constructed and evaluated for performance comparison. The Performance metrics include Mean Absolute Percentage Error (MAPE) and Mean Squared Error (MSE). The suggested STLF CFNN prediction model outperformed shallow feed forward networks on both performance metrics with prediction errors of less than 1%.

Generic approach to calculation of short circuit currents in power transformers
Authors: Capuder Kosjenka , Plišić Goran , Štih Željko
Published: July 2022

Power transformer in service is exposed to various voltage and current stresses. The ability to withstand short circuit is an essential requirement for power transformers. There are different types of short circuit: single - phase to earth, double - phase with or without simultaneous earth fault and three - phase short circuit. These various short circuit conditions result in different stress conditions for the windings. Mesh analysis and symmetrical components are the two methods most commonly used for determining the magnitude of short circuit currents. In this paper, both methods will be presented with results compared on a real-case transformer. Also, a generic scheme using the symmetrical components approach is designed in order to standardize the short-circuit currents calculation for all power transformer types and to reduce the time required for obtaining results.
Insulation optimization of power transformer leads
Authors: Marković Mladen
Published: July 2022

Power transformers reliability, amongst other things, depends on its insulation system. High voltage leads are a part of the insulation system and should be properly insulated. This includes positioning an insulation barrier between the leads and a tank on a certain distance. This distance affects the safety factors (breakdown probability) for such system. The paper presents optimization process with which both the breakdown probability and leads vs. tank distance could be minimized. It also proposes a method with which this optimization process could be confirmed.
Case study on transformer models for calculation of high frequency transmitted overvoltages
Authors: Jurišić Bruno , Uglešić Ivo , Xemard Alain , Paladian Françoise
Published: July 2022

Events such as lightning, switching of vacuum circuit breaker or switching operations in gas insulated substation (GIS) generate high frequency overvoltages. An equipment in a transmission or a distribution system has to be protected against such phenomena. Unfortunately, the traditional transformer models available in Electromagnetic transient simulations program (EMTP-like) software packages are not capable of representing transformer behavior in a transient state, which includes high frequencies. Moreover, high frequency transformer models are often too complex or require confidential information on transformer geometry. However, in the design stage of insulation coordination it is particularly important to accurately calculate transmitted overvoltages through transformers. In the scope of this paper two different transformer models for high frequency, are developed in an EMTP-type software program. The first model named “Black box” derives solely from the values measured on the transformer terminals and does not require any knowledge of the transformer inner geometry. The second model named “Grey box”, is based on a lumped RLC parameters network, whose values are derived from the simple geometry of the transformer window and from the nameplate data. Furthermore, the models’ capabilities to characterize a transformer at high frequencies are analyzed. The case study is done on a distribution transformer which is to be located inside a power plant. The transmitted overvoltages calculated with the models in the EMTP-type software program are compared with measurements.
