CHALLENGES OF JUDICIAL PRACTICE FOR LITIGATIONS RESULTED FROM FOREIGN ECONOMIC TRANSACTIONS
Authors: GUBAREVA A.V.
Published: January 2023

A specific nature of foreign economic relations determines a need for the generation of a new approach to the structure of its legal regulation. Its specificity is that the legal regulation of the aforementioned relations is formed in the context of various spheres of public life and branches of law. Relevant issues of judicial practice regarding litigations resulted from foreign economic transactions are examined in the paper. The research is based on the objective dialectic method of cognition of legal phenomena and procedures related to the selected topic and of the examination of their interconnections. Besides, the research is based on general scientific methods: analysis, synthesis, historical and logical methods, generalization, abstraction, system analysis, modelling and others. Currently, the national economy obviously tends to develop in a sinusoidal manner. It requires considering the possibility (in the frameworks of development of the intersectoral institute of foreign economic law) of using a chance to improve the mechanism of legal regulation in the field of state control over the external economic activities with a focus on judicial practice. The conducted research develops and specifies a theory of intersectoral linkages in respect to the relations in question. As a result of the conducted research, a unique legal regime of intersectoral functional legal institute of foreign economic law is established to change more prominently with the transformation of legal and objective realities.

Two-Stage Model of Silicate Glass Transition
Authors: Cheng Shangcong
Published: January 2023

After several decades of study, the nature of the glass state and glass transition remains controversial. This work describes a newly proposed two-stage model for silicate glass transition. The model recognizes that there is a cooling rate independent critical temperature Tc, separating two temperature regions. The coherent structures in the two regions change along different paths. All observed dynamic features in the glass transition result from structural rearrangements in the process. According to the proposed model, the silicate glass transition can be recognized as a second-order phase transition following an incomplete first-order phase transition. This work will first describe the two-stage model, and then apply the model to silica glass, as well as binary and ternary silicate glass transitions.
Consolidation of Central Columns of Civil Multistory Structures to Increase the Critical Buckling Force
Authors: BOTIȘ Marius , PLEȘCAN Costel
Published: January 2023

Civil multi-story structures are used as office buildings or residential buildings. The central pillars on the ground floor of the civil structures will have the largest gravitational load and implicitly will be the pillars most stressed in compression. In this paper, the authors propose to increase the critical buckling load of the central pillars on the ground floor in the event that it is necessary to strengthen these pillars, due to the change in the purpose of the building and the modification of the loads on the floors. To increase the buckling load in the case of these columns, it is proposed to increase the moment of inertia of the columns on the base region. To highlight how the critical loss of stability load changes, a theoretical model is made for the column with constant section and another for the column with variable section in steps. Finally, the results obtained for the critical load will be compared and it will be highlighted what is the increase in buckling load for the pole with variable section in relation to the pole with constant section.
Research on Heat Treatment Applied to High Strength Construction Steels
Authors: NEACȘU Marian-Iulian
Published: January 2023

The paper presents the research carried out on a laboratory scale in order to establish the heat treatment parameters for the thick sheets used for naval constructions (welded joints). Investigations were carried out on steel sheets with two different chemical compositions.In the same cooling conditions, returns were made at different times and temperatures. For the different sheet thicknesses of 15, 20, 22 and 24 mm, various heat treatment options were performed, by changing the cooling conditions of the sheets, respectively the cooling speeds, conditions that can be achieved in the industry.The laboratory results showed that the required values for the mechanical characteristics are obtained only by cooling in water under pressure followed by a return at temperatures equal to or greater than 650 °C, a time greater than 70 min.
A Sensitivity Study of the Maximum Stress in a Rubber Circular Ring to the Coefficient of Friction Using FEM
Authors: BOAZU Doina
Published: January 2023

The paper presents a sensitivity study of a rubber circular ring (O-Ring) depending on the value of the coefficient of friction (design parameter) between the ring and the surfaces between which it is mounted. The response value is the maximum von Mises stress in the rubber ring. The influence of temperature was not taken into account.Through this sensitivity nonlinear analysis using finite element modeling, the correlation between Equivalent maximum Von Mises Stress and Friction coefficient can be established, determining a maximum stress level of the rubber ring to the friction coefficient. This relationship is important for the preload stage of the gasket functioning.

Recent and extensive reports on the development of preparation methods that can lead to obtaining various nanostructured polymeric materials, including the preparation of nanoparticles, nano-capsules, nano-gels, nano-fibres, dendrimers and nano-composites, have been presented in the literature to provide a picture of the complexity of the field, and the diversity of approaching methods. From the data presented by various researchers, it appears that by ensuring a rigorous control of the nano-structuration of polymers and/or by adding nano-particles to the polymer matrices, improvements in structural and functional properties can be achieved in a significant number of polymer systems as a response to the continuous demands of industrial advanced sectors. Until now, most of the studies on polymer blends have been related to the control of their physical and chemical properties, their barrier properties or their electrical conductivity. This paper briefly presents various applications of resins (thermoset polymers) used to synthesize some polymer materials and blends.

Authors: ALEXANDRU Petrică , ŞTEFĂNESCU Cristian
Published: January 2023

Sintered copper-tin alloys are used to obtain products with numerous applications. Some bronze parts such as filters or bushings for self-lubricating bearings can only be produced by specific powder metallurgy technologies. Metal filters represent an important fraction in the field of sintered products. In the paper, measurements of the intergranular bridges were made on the samples obtained by sintering the spheroidal powder from the CuSn12 alloy. Free casting in graphite moulds followed by sintering was used (9 experiments, 3 temperatures x 3 durations). With these data, the coefficients from the Kuczinski equation were determined. Thus, the correlation between the desired porosity for a filter-type product (expressed by the size of the intergranular bridge) and the sintering technological parameters can be established.

Authors: HERBEI Elena Emanuela
Published: January 2023

Thin polymeric films with dielectric properties become a very important part of today’s devices, being indispensable in industry, electrical applications and not only. Nowadays polymeric materials have attracted attention in academic and industrial research due to the miniaturization at the micro and nanoscale of different electronic devices. Polymers in general are used for their light weight, good mechanical strength, dielectric properties, and optical properties, which make them multifunctional materials.This paper presents research on polymethyl methacrylate (PMMA) thin films obtained by the sol-gel method. The optimization of thin film PMMA layers has been a problem due to the importance of using the polymer in the different electronic domains. Thin films of PMMA with different thicknesses were deposited onto glass and silicon wafers in order to measure dielectric properties. For dielectric properties, the PMMA thin layer was inserted in a metal-insulator-metal structure (MIM). In order to observe the morphology and roughness of thin film, optical microscopy, scanning electron microscopy and atomic force microscopy have proceeded.The dielectric constant (k) was calculated using the electrical capacitance formula. The I-V and C-V curves showed a dielectric behavior with a leakage current between 10-11 and 10-8 A and a constant capacitance in the bias range ± 5 V.

This article intends to provide a reflection that leads educators to knowledge that relates the brain, its maturity and perception, to learning. Thus, it presents itself with the theme: Neurosciences in the context of school education: the stimulation of learning. It is believed that the human mind was constituted and there is no way to understand how it is organized with a traditional view of intelligence. Therefore, the current educator needs to know and reposition himself in the face of new studies and discoveries about the human mind and intelligence. Thus, the objective is to analyze, in the existing literature, neuroscience in training and pedagogical practice, as a tool for learning. The research took place through exploratory and reflective bibliographic research, with the contribution of authors such as: CARVALHO (2010), FONSECA (2015), OLIVEIRA (2011), RELVAS (2012, 2016, 2018), it is possible to understand the issue of neurosciences in education as a facilitator from understanding to the teaching-learning process and its difficulties, also highlighting issues such as motivation, emotion and memorization. Pedagogical action needs to be carried out by new discoveries that help in the classroom process and that search for new visions, as allowed by neuroscience. It becomes necessary to enable the student to enjoy learning, rescuing lost interests due to the difficulties not addressed.

INTERNAL AUDIT FUNCTION, MANAGEMENT SUPPORT AND CORPORATE GOVERNANCE IN PUBLIC SECTOR
Authors: Jaffar Nahariah , Mohd Faizal Sellywati , Alias Norazlan
Published: January 2023

Having strong corporate governance (CG) in public sectors is very imperative. An effective CG may, to some extent, prevent mismanagement of public monies. Internal audit function might be a significant contributor to achieve this. However, little attention was given on the role of internal audit function within public sector’s CG subject. As such, this paper presents a conceptual discussion on the potential effects of internal audit function attributes on the Malaysian public sector’s CG, and the potential moderating effect of management support on this relationship. Institutional and agency theories were employed to synthesise relevant literature on internal audit function, management support, and CG in public sector setting. Subsequently, a conceptual framework was developed and ten propositions were established. The originality of this paper was in its comprehensive arguments on the possible association of internal audit function attributes on CG of the Malaysian public sector. Moreover, this paper attempted to examine the role of management support in this association. Additionally, the use of the institutional and agency theories offered essential insights pertaining to internal audit function attributes and management support subjects within the context of CG of the public sector. This study is timely in that it offers insights into how the internal audit function may improve the management of public financial resources.

Having a sense of willingness to communicate in the 2nd language (L2) is one
of the important factors in improving L2 speaking skills. Willingness to
Communicate (WTC) a model proposed by MacIntyre et. al (1998) is
considered an indicator for successful English learning outcome. There are
several factors that influences students’ WTC in English. Hence, the objective
of this study is to look into the individual factors that influences pre-university
students WTC in English in an ESL digital classroom setting. The result of the
study was obtained through the use of qualitative method using a focused group
interview of 25 voluntary pre-university students in a public university in
Sabah, Malaysia. The data obtained revealed that individual factors which are
self-confidence, language anxiety, motivation and grit play a role in
influencing pre-university students’ WTC in English. This finding would be
beneficial to language instructors as well as syllabus makers in providing and
designing an English lesson that is geared to encouraging students to
communicate in English.
ACQUISITION OF RARE EARTH MINERALS FROM MALAYA IN VIOLATION OF EXPORT CONTROL LAWS FOR JAPAN’S ATOMIC RESEARCH DURING WORLD WAR II
Authors: Abdul Majid Marina
Published: January 2023

During World War II (WWII) from 1941-1945, the Japanese sought to obtain uranium and thorium from Malaya meant for its atomic research. This may violate international export controls or the domestic laws of the United States (US) and the United Kingdom (UK). The main objective of this study is to investigate the extent of the Japanese acquisition of uranium and thorium in Malaya for its atomic research during WWII which may or may not have violated international or domestic export control laws of the US and UK. This qualitative study used a textual analysis for interpreting bilateral and trilateral agreements to secure uranium and thorium, the export control laws of the US and UK, and a case law. Other documentation concerning Japanese procurement of amazing in Malaya was referred. Secondary resources of books, book chapters, conference papers, journal articles, newspapers, magazines, and internet materials were also analyzed through content analysis. The write-up for this study is narrative as this study relates to history, law, and security studies. The results of this study indicate the Japan Nitrogen Company based in Malim Nawar had produced carbide, ammunition and ammonia. While this company’s branch in Hŭngnam, North Korea had been scouting for minerals for Japan’s atomic research, it is unknown if the unit in Malaya also played the same role. Amang was shipped to Japan for the extraction of monazite which in turn returned thorium and uranium were used for atomic research but some were sunk at sea or confiscated as war bounty by the US. Penang Island became a transit point for uranium sent by the Germans to the Japanese. The US and the UK export control laws were the most applicable in restricting Japan from acquiring uranium and other minerals for atomic research as international controls were just emerging and applicable among a few selected countries to yet become an accepted norm multilaterally.
FEDERALISM: A CONCEPTUAL AND THEORITICAL PERSPECTIVE
Authors: Zahrin Zuriana , Mohamed Ahmad Martadha
Published: January 2023

Federalism, according to Elazar (1995), is an inevitable heterogeneous field that is rather difficult to discuss satisfactorily on a conceptual and theoretical level. Although the greatest strength of federalism is its adaptability or flexibility, this adaptability leads to ambiguity and creates significant conceptual and theoretical challenges, as mentioned by Erk (2006, p. 105) in a tangled mess of federalism definitions and context. Due to the fact that federalism already takes into account several perspectives, the terminology has been interpreted in various ways and adapted to match the various issues. Federalism is context-based, and context determines meaning. Since there is no commonly accepted definition of federalism (Ogunnoiki, 2017), federalism theories have also become a bigger, more complex topic that has gotten scant attention (Paleker, 2006). Given that the context of federalism is multifaceted and applied or understood differently by different people or perspectives, this paper compiles federalism concepts and theories used by scholars and researchers from various perspectives.

Given the need to reduce greenhouse gas emissions, new energy-efficient solutions can be adopted for construction and agricultural machinery. Such a solution is a digital hydraulic cylinder that uses several active areas and a constant pressure supply with which a gradual variation of the driving force can be obtained. Traditional hydraulic systems have high energy losses due to the need to direct and throttle the flow through different valves. The article presents simulations in the AMESim environment and laboratory experiments of a digital hydraulic cylinder with three active areas. Through numerical simulations, the authors aim to highlight the energy efficiency of a digital hydraulic cylinder compared to a hydraulic cylinder in a conventional drive.

Many organizations carry out the quality assurance system through the Internal Quality Assurance System (SPMI) and the External Quality Assurance System (SPME). The SPMI framework uses the stages of a continuous quality assurance cycle with the PPEPP method (Application, Implementation, Evaluation, Control, and Improvement), which is carried out periodically to achieve University's Vision, Mission, Goals, and Targets. This paper discusses the implementation stages of the internal quality audit management system at Universitas Respati Yogyakarta, Indonesia. Using an information system, the university audit body, BPM, regularly and consistently carries out an Internal Quality Audit (AMI) every year to audit the implementation of academic and non-academic activities at the University. In this research, we construct an audit system, namely the E-Audit application, with the Waterfall software development method. This study can produce an efficient system called SIMANTUL, which refers to the Higher Education Accreditation assessment instrument version 3.0 and can store documents digitally.

Character recognition is very important to understand ancient culture. Various papers proposed numerous to deal with handwritten character recognition. However, several traditional remain drawbacks because methods still rely on operations based on visual capabilities. Therefore, to deal with the issue, we propose a novel recognition model using a Convolutional Neural Network to produce an effective result. To build the model, we collect datasets, do preprocessing, training with several different parameters to get the highest accuracy results. Based on experiments, our proposed model can produce an accuracy quality with a value of 98.00%.

Field research was conducted to determine the availability and condition of soil micronutrients at the Teaching and Research Farm in Malete. The goal of the study is to assess the distribution and status of micronutrients and how they relate to a few key soil characteristics. A total of 173 soil samples were collected and compressed into 7 composite samples. Iron (Fe), Copper (Cu), Zinc (Zn), and Manganese (Mn) were the micronutrients determined in the laboratory using the Mehlich-III multi-nutrient extraction method. The particle size distribution (sand, silt, and clay), pH, and organic carbon of the soil were determined. The findings indicated that the soils of the teaching and research farm have a sandy loam texture, with sand concentrations of 80.64–82.64g/kg, silt at 6g/kg, and clay at 11.36–16.34g/kg. The results of the soil reaction revealed that the soils have minimal organic content (0.06-0.93g/kg) and are extremely acidic (5.1). The result of the soil micronutrients indicates that Fe content was high ((0.10-0.20mg/kg); copper was rated low (0.04-0.05 mg/kg); zinc was rated low (0.01-0.03 mg/kg) and manganese was also rated low (0.07-0.11mg/kg) respectively. The findings show that the key soil characteristics that affect the availability of micronutrients in the soil are sand particles, pH, and organic matter because of their substantial correlations. The highly substantial link between the investigated accessible micronutrients suggests that similar processes regulate both their availability and release to plants. Since the soils are suitable for the development of arable crops, additional applications of Fe-rich fertilizer won't be necessary, but a complementing supply of Fertilizers containing copper, zinc, and manganese is highly advised to improve the region's soil fertility.

In the structure of the Kwara Agricultural Development Programme, the position of Zonal Extension Officers (ZEO) is vital and central to the execution of the extension programmes which are implemented through the frontline Extension Agents. The study examined the leadership effectiveness of the Zonal Extension Officers (ZEOs) in Kwara State Agricultural Development Programme, factors that hindered the leadership effectiveness of ZEOs and the demographic characteristics of ZEOs and Extension Agents (EAs) in Kwara State Agricultural Development Programme. One hundred and thirty (130) EAs and four (4) ZEOs were purposively selected for the study. Primary data were collected with a structured questionnaire and analysed with descriptive statistics while the hypotheses were tested with Pearson Product Moment Correlation and Chi-Square Statistics. Results of the study revealed that 94.6% of the EAs and all four ZEOs acquired tertiary education. The EAs and the ZEOs had an average of 8.01 and 5 years of field experience respectively. Furthermore, 59.2%, 58.5% and 50% of ZEOs were effective only in clarifying the organization’s goals, ineffective in staff motivation and communication respectively.   There was a significant relationship between level of education (χ2 = 47.53, p=<0.05), years of experience (r=0.27, p=<0.05) of EAs and perceived leadership effectiveness of ZEOs. Based on the empirical evidence, the ZEOs need to improve their job performances. Extension personnel should acquire tertiary education with cognate field experience before they could function as ZEOs for optimum effectiveness.
