Verborgene Gegenwart
Authors: Koenig Katrin
Published: May 2024

Wie kann Gottes Gegenwart trotz ihrer Verborgenheit wahrgenommen werden? In dem folgenden Beitrag möchte ich zeigen, wie Simone Weil die Erfahrungen der Verborgenheit und der Abwesenheit Gottes als Signatur des Unglücks und der Entwurzelung der Menschen in der Moderne analysiert. Des Weiteren wird dargestellt, wie Simone Weil vor diesem Hintergrund mit einer kreuzestheologischen Denkfigur reflektiert, wie die Gottesliebe in besonderer Weise im Unglück verborgen anwesend sein kann, trotz Erfahrung der Abwesenheit Gottes. Hier schließt sich die erkenntnistheoretische Frage nach der Wahrnehmbarkeit der verborgenen Gegenwart Gottes an. So soll ausgeführt werden, wie Simone Weil aufzeigt, wie durch ästhetische Formen der Schönheit und Ordnung der Welt, durch ethische Formen von Nächstenliebe und Freundschaft und durch die religiöse Formen in Liturgie und Gebet als höchster Form der Aufmerksamkeit die verborgen gegenwärtige Gottesliebe indirekt wahrgenommen werden kann. Dies spricht schließlich für eine andere Deutung der Verborgenheit Gottes als im sog. Verborgenheitsargument von J. L. Schellenberg, mit dem von der Verborgenheit auf die Nichtexistenz Gottes geschlossen wird.

Authors: Ji Cong , Yang Shan-shan , Gu Fan
Published: May 2024

This study explains the conductive mechanism of C12A7:C from the perspective of crystal structure. C12A7:C is a carbon derivative of C12A7 and prepared by CaCO3 and Al2O3 in sealed graphite crucible through high-temperature sintering experiments. The main component was confirmed to be C12A7:C through X-ray diffraction inversion analysis. The four-probe method revealed that it is a semiconductor with conductivity of 4,339 S/m. A conductive model of C12A7:C crystal was established to study its conductive mechanism. Through theoretical calculations of the conductive structure model, the density of states and transfer function are important factors determining the conductivity of C12A7:C crystals. Based on the analysis of these two factors, C is the key to electron transfer in the C12A7:C crystal. Further research indicates that the C–C bond is the main form of C in C12A7:C crystals. These C–C bonds satisfy the formation conditions of conjugated systems and are key to the conductivity of C12A7:C crystals. Through simulation calculations, the volt ampere characteristic curve of C12A7:C exhibits Ohmic conductor characteristics. The conductivity of C12A7:C obtained through theoretical calculation is consistent with the experimental results. In conclusion, the conductivity of C12A7:C crystal is mainly due to the C–C conjugated system formed by carbon atoms in the crystal.

Published: May 2024

Objectives

This pilot study aimed to evaluate the efficacy of the 4-h mean lactate clearance (LACclr) level as a predictive factor for in-hospital outcomes, 30-day mortality, and treatment success in patients with acute cardiogenic pulmonary edema (ACPE), a significant clinical form of acute heart failure (AHF).

Methods

A total of 44 patients diagnosed with acute pulmonary edema were included in the study. The patients were divided into two groups based on lactate levels and negative outcomes, and lactate and LACclr levels and negative outcomes were analyzed using statistical tests such as Fisher’s exact test, Student’s t-test, Mann-Whitney U test, and Receiver operating characteristic (ROC) analysis.

Results

The results indicated a statistically significant difference in the total hospitalization length of stay according to whether the patients had a negative outcome (intubation and in-hospital mortality) (p=0.033). Additionally, the area under the curve (AUC) value for 4-h mean LACclr was 0.795 in all patients, which was statistically significant in predicting 30-day mortality (p=0.033). The optimal cut-off value for the 4-h mean LACclr in predicting 30-day mortality was found to be 5.57 %, with 80 % sensitivity and 66.7 % specificity. The threshold to rule out 30-day mortality for all patients was 18.85 with 100 % sensitivity and 30.2 % specificity (AUC, 0.795 95 % CI [0.546–1.000], p=0.033).

Conclusions

These findings suggest that the 4-h LACclr level, calculated within 4 h of emergency department (ED) presentation, can be used as a predictive indicator for needing intubation, in-hospital mortality, and 30-day mortality and to identify patients at higher risk for adverse outcomes.
Aquinói Szent Tamás a helyes államról és kormányzásról
Authors: Frivaldszky János
Published: May 2024

In this paper we discuss St. Thomas Aquinas’ theory of the state and political government. We seek to answer why he believed that the best form of government is kingship. We will look at how to avoid the danger of the best form of government being distorted into its opposite, the worst form of government, tyranny. The criteria for this will be examined, and then we will analyse the second best form of government that can be implemented, a mixed government of limited monarchy. St. Thomas, although he lived in the age of constitutional charters and was familiar with them, chose the government of virtuous persons for the common good, rather than the constitutional system of charters based on ’institutionalised distrust’.
Neuronal Subtypes and Connectivity of the Adult Mouse Paralaminar Amygdala

Published: May 2024

The paralaminar nucleus of the amygdala (PL) comprises neurons that exhibit delayed maturation. PL neurons are born during gestation but mature during adolescent ages, differentiating into excitatory neurons. These late-maturing PL neurons contribute to the increase in size and cell number of the amygdala between birth and adulthood. However, the function of the PL upon maturation is unknown, as the region has only recently begun to be characterized in detail. In this study, we investigated key defining features of the adult mouse PL; the intrinsic morpho-electric properties of its neurons, and its input and output circuit connectivity. We identify two subtypes of excitatory neurons in the PL based on unsupervised clustering of electrophysiological properties. These subtypes are defined by differential action potential firing properties and dendritic architecture, suggesting divergent functional roles. We further uncover major axonal inputs to the adult PL from the main olfactory network and basolateral amygdala. We also find that axonal outputs from the PL project reciprocally to these inputs and to diverse targets including the amygdala, frontal cortex, hippocampus, hypothalamus, and brainstem. Thus, the adult mouse PL is centrally placed to play a major role in the integration of olfactory sensory information, to coordinate affective and autonomic behavioral responses to salient odor stimuli.

Published: May 2024

The competitive play of digital games, esports, has attracted worldwide attention of hundreds of millions of young people. Although esports players are known to practice in similar ways to other athletes, it remains largely unknown what factors contribute to high performance and to what degree. In the present confirmatory study, our goal was to test whether deliberate practice theory, which has successfully been applied to other sports earlier, can predict high esports performance with other psychologically relevant variables. The study was carried out with participants from Counter-Strike: Global Offensive (N = 186) and League of Legends (N = 411). In both esports, we found evidence for deliberate practice not having a meaningful effect on performance (null: r > .3 in Counter-Strike: Global Offensive and r > .2 in League of Legends, observed: .02 in Counter-Strike: Global Offensive and -.01 in League of Legends). On the other hand, the results confirmed younger age predicting better performance (-.33 and -.22, respectively). Additionally, we were able to confirm two game-specific findings: attention (-.30, Counter-Strike: Global Offensive) and non-deliberate practice hours (.26, League of Legends) meaningfully predicted performance in one but not both esports. The effects of all other variables—including intelligence, reaction time, and persistence—were confirmed to be null or inconclusive in both esports. We discuss the results against game design and hypothesize esports-specific information density as a potential explanation to differences in performance prediction. The findings can be useful for esports teams, coaches, and all individuals pursuing success in esports.
Whose Security? Conflict and (Critical) Security Studies in the Middle East and North Africa
Authors: Abboud Samer
Published: May 2024

Security Studies (SS) is a subfield of International Relations (IR) concerned with the ways that conflict and violence contribute to shaping the world. The subfield’s concern with the conditions of war and peace has situated the state as the referent object of security and produced a state-centrism in scholarship, academic journals, and teaching that overemphasizes security as a policy problem. Beginning in the early 1990s challenges to state-centrism emerged through Human Security (HS) and Critical Security Studies (CSS) approaches that sought to challenge and rethink the referent objects of security while introducing more critical theoretical traditions from which to research, publish, and teach about what constitutes threat and security. These new approaches expanded inquiry into security and oriented scholars around different ways of approaching questions of what security is and for whom (or what) it is produced. Despite the expansion of the different subfields of inquiry into security, a common criticism levelled at these approaches concerned how regions of the Global South were incorporated into scholarship.

In this reflective essay, I draw inspiration from these criticisms to ask how the Middle East and North Africa (MENA) has been studied, taught, and theorized from in the fields of Security Studies and Critical Security Studies. The principal question guiding this essay is What do different traditions in Security Studies have to tell us about conflict in the Middle East and North Africa? I seek to reflect on how the region, its peoples, and their experiences are incorporated into these fields and how this has shaped scholarly and popular understandings of conflict and peace in the MENA. I wish to reflect on how tensions between the MENA’s incorporation into SS and CSS produce patterns of visibility and invisibility. I then shift attention to a discussion of how the emergent scholarship on non-Western IR and other approaches from within the MENA region itself may contribute to different ways of researching and teaching conflict and security in the MENA. The essay concludes with some observations about the future of conflict and security studies in the MENA with an emphasis on key questions that are raised in the context of the region’s contemporary overlapping crises.

Published: May 2024

The need to address global concerns has led to an increase in the significance of sustainable capitalism, which is located at the intersection of economics, business, and environmental studies. This study aims to delve into the theoretic evolution and academic structure of the relationship between sustainability and capitalism, by employing a bibliometric analysis. Relying on 687 documents, sourced from the Scopus database, this paper provides a thorough overview of the evolution of sustainable capitalism, highlighting significant turning points, essential themes, and new research directions. VOS-Viewer and R-Studio were used for implementing the techniques of citation, co-citation, and keyword analysis. The findings from the study have implications for multiple stakeholders. While the analysis could help researchers have a better understanding of the field and explore future research agendas, it can push the corporate houses to take necessary remedial actions for their past capitalist behavior. The study will also be beneficial for developing countries to understand the pressing issue of environmental damage and come up with cheaper yet effective ways to implement circular models of the economy.
Unraveling the Loan Growth Threshold Effect on Non-Performing Loans During Total Dollarization in Zimbabwe
Authors: Katuka Blessing , Mudzingiri Calvin , Vengesai Edson
Published: May 2024

The availability of bank loans is a vital component in determining the investment and spending patterns that influence economic growth. This article examines the threshold effect of loan growth on non-performing loans (NPLs) in the Zimbabwean banking industry during dollarization. The study employed panel threshold regression models developed by Seo et al. (2019) and Kremer et al. (2013) on a panel of thirteen banks from 2009 to 2017. The study revealed that locally owned banks held a higher percentage of NPLs (12.7%) than foreign-owned banks (6.1%) during the period under study. The study also documents a loan growth threshold level of 38%. On average, the industry lends excessively, as demonstrated by the 48% loan growth rate. Primarily, local banks dominate this rate by lending above the threshold compared to foreign banks. The study observed that, below and above the threshold, loan growth exerts a negative and significant effect on NPLs. Based on the results, it can be recommended that banks should devise strategies to maintain a steady loan growth rate, enhance profitability, and effectively monitor liquidity risk exposure. The findings provide insights into reviewing bank credit policies and prudential guidelines.

The work was aimed at developing an adhesive formulation with increased adhesive strength for metals. It contains an epoxy resin of the bisphenol type СHS-TROXY 520 (an analogue of ED-20), an amine hardener triethanolamine (TEA) and a silicon-containing component (3-isocyanatopropyl)triethoxysilane, designated as NCO-Si, with an optimal ratio of components. The content of NCO-Si in the formulations was 0.5, 1.0, 3.0 and 5.0 wt. %, respectively. The gradual transformation of the epoxy system into a three-dimensional network with the formation of ester and urethane groups was shown by IR spectroscopy method. Tensile and shear strength were determined using the tearing machine R-50 in accordance with current standards. It was found that the maximum values of physical and mechanical parameters were obtained when the amount of NCO-Si was 3 wt. %. The maximum values of adhesion strength to steel substrates δst. = 58.5 MPa significantly exceed those for neat epoxy formulations. The shear strength values for steel plates τst. = 21 MPa increase by 60 %, for aluminium plates they are δAl =14.5 MPa and increase by 48 %. The morphology of the samples has been studied by means of optical microscopy. It is shown that the modified NCO-Si samples are characterised by a phase-separated structure. At a minimum amount of NCO-Si (0.5 wt. %), structurally disordered spherical domains with a size of ~1÷3 μm are observed, an increase in the content of the organosilicon component leads to the formation of interconnected regular structures, which are less pronounced at 1.0 wt. % of NCO-Si and clear at 3.0 and 5.0 wt. % of NCO-Si. Thermogravimetric analysis (TGA) was performed as well. It is shown that the modification of epoxy resin by a silicon-containing component with NCO-Si groups leads to an improvement in thermophysical parameters, a decrease in internal stresses and the formation of a material with a structure close to equilibrium.

Authors: Aicha Zouaneb , Sakher Elfahem , Rachid Tigrine , Abdallah Bendoura , Benselhoub Aissa
Published: May 2024

The object of research is the complex realm of energy localization and coherent ballistic electronic transport within low-dimensional silicon quantum wires, specifically those doped with germanium atoms. Unlike their three-dimensional counterparts, low-dimensional systems exhibit unique electronic transport behaviors, necessitating novel analytical approaches for a comprehensive understanding. The core of this investigation leverages the Phase Field Matching Theory (PMFT) and the tight-binding (TB) approximation, sophisticated methodologies that enable a deep dive into the quantum mechanical nuances of these systems. Through this lens, we examine the intricate dynamics of dispersion relationships, phase factors, group velocities, and notably, the impact of defects introduced by the germanium doping.
This research meticulously analyzes how these defects affect electronic and thermal conductivities, along with densities of states, offering new insights into the role of Fano resonances in the fluctuation of transmission and reflection spectra. These resonances, we find, are crucially dependent on the nature of the defects, their configuration, and the electronic parameters in their vicinity, underscoring the nuanced interplay between material composition and electronic properties in low-dimensional systems.
The implications of our findings extend far beyond the theoretical. They pave the way for significant advancements in nanotechnology and the design of electronic devices, highlighting the potential for creating more efficient, high-performance components. Furthermore, this work proposes a framework for developing non-destructive testing methodologies that could revolutionize material science by enabling the precise analysis of defects in low-dimensional systems without causing damage. This is particularly critical for the ongoing development of materials with optimized properties for various applications, from electronics to energy storage.
In essence, this research not only enriches our understanding of the physics governing low-dimensional systems but also offers practical insights into leveraging these properties for technological innovation. By bridging the gap between theoretical physics and material science, our study sets the stage for the next generation of electronic components and non-destructive evaluation techniques, marking a significant step forward in the application of quantum mechanics to real-world challenges.

Authors: Kazak Iryna , Sidorov Dmytro
Published: May 2024

The object of research is the design of a jaw crusher for crushing limestone for the production of silicate bricks. The article is devoted to the study of the problem of reducing the efficiency of material crushing in a jaw crusher. The efficiency of crushing materials in jaw crushers ensures the quality of manufacturing bricks, etc. Therefore, this work is aimed at choosing a way to improve the design of the jaw crusher to increase the efficiency of material crushing.
The article defines the classification of jaw crushers, their advantages and disadvantages, describes the principle of operation of the most widely used jaw crushers in the construction industry with simple and complex rocking of the cheek. A literature and patent search and analysis of existing methods of increasing the efficiency of material crushing in jaw crushers was carried out. As a result of the literature and patent search, one of the methods of improving the design of the jaw crusher to increase the efficiency of material crushing based on the use of longitudinal protrusions on the movable jaw was selected and proposed. The protrusions on the flat sections of the working surface of the plate are made with the same pitch of their location within each section with a decrease in the pitch of the protrusions in the direction of distance from the upper part of the plate. The considered design of the movable jaw with longitudinal protrusions in the jaw crusher will ensure reliable pulling of the material into the gap between the movable and stationary jaws, which ensures high contact stresses acting on the crushed material from the side of the working surface of the plate.
Compared to known designs of jaw crushers, the improved design of the movable jaw in the jaw crusher with longitudinal protrusions of different sizes with a decrease in their size in the direction from the upper part of the plate on three sections of the working surface of the plate will contribute to ensuring high contact stresses acting on the crushed material from the side of the working surface cheeks, during its advancement between the moving and stationary cheeks and increases the efficiency of destruction of various materials.
Compared to known designs of jaw crushers, the improved design of the jaw crusher has a movable jaw with longitudinal protrusions of various sizes. At the same time, these protrusions are located on three sections of the working surface of the plate with a decrease in their size in the direction from the upper part of the plate. This will help ensure high contact stresses acting on the crushed material from the side of the working surface of the cheek, during its advancement between the moving and stationary cheeks. Also, this design of the working jaw of the jaw crusher with longitudinal protrusions helps to increase the efficiency of destruction of various materials.

Authors: Zubko Tetiana
Published: May 2024

The object of research is a list of the main factors of influence of the foreign economic sphere on the level of economic security. The effective development of the national economy largely depends on the state and level of economic security of the country in the conditions of strengthening globalization and integration processes. An adequate level of economic security is the basis for the development of socio-economic systems of any level, stability in society in general. Therefore, assessment and analysis of factors affecting economic security at different levels (countries, businesses, enterprises and organizations) is an important direction of the analytical work of specialists. For its implementation, analysts need a methodology – to determine the goal and interests, the main influencing factors and principles, to choose methodological and analytical tools. In the scientific works of economists, the methodology, level, and indicators are given as separate aspects of the formation and management of the economic security of the state. Without denying the significant contribution of these developments, the conducted research sets out the systematization of factors influencing the state of the macroeconomic environment. The study of factors influencing the macroeconomic sphere on the level of economic security of the country is based on the use of indicators calculated from available statistical data. The last twenty years, which showed an increase in world GDP almost twofold (from 51.39 trillion USD in 2000 to 101.12 trillion USD in 2020), are characterized by the loss of opportunities for the Ukrainian economy to be present on the world stage a market where competition is intensifying and carried out at a new technological level.
The work defines the national economic interests of Ukraine in the global socio-economic space, the directions of the realization of the national interests of Ukraine, the dynamics of indicators of the development of the macroeconomic sphere. This made it possible to form a list of the main influential factors of the macroeconomic sphere, which directly shape the level of economic security of the state. The results of the research can be useful for the formation or adaptation of development strategies of countries with similar conditions and economies, such as Georgia, Moldova, which also have conflicts with Russia and seek to join the European Union.

Assessing the pressure variation in the plunge pool of Yusufeli dam
Authors: Yilmaz Davut , Basar Tugce , Ozkaya Arzu
Published: May 2024

In dam engineering, plunge pools are critical terminal structures, often causing substantial scour that poses risks at the foot of the dam. Scouring near dams is a nationwide concern, as it has led to more dam failures than any other cause. Thus, evaluating hydrodynamic pressures from impinging jets is crucial for pool floor stability design. This study utilised physical models, experimental facilities and computational fluid dynamics models to assess hydrodynamic pressures at Yusufeli dam. Results indicate that Flow-3D analysis and empirical equations yield similar pressure readings on the bottom of the plunge pool, one-third of the free fall pressures of the physical model. The physical studies using Froude similitude revealed drastically lower Reynolds numbers compared to prototype flows, affecting turbulence and air entrance simulation. Consequently, model-scale resistance issues dominate physical model calculations, introducing uncertainty. This study underscores the importance of carefully assessing hydrodynamic pressures on plunge pool floors, as modelling approaches significantly impact results.

Published: May 2024

This paper examines the vibration response of the steel–concrete composite ultra-shallow floor beam (USFB) flooring system, which incorporates asymmetric steel perforated beams to accommodate the concrete floor slab within the depth of the flanges while allowing reinforcement and/or service ducts to pass through the web openings. This is a lightweight flooring system that can accommodate long spans, thus becoming susceptible to floor vibrations due to external resonant dynamic loads. To investigate the influence of slab thickness and boundary conditions on the natural frequencies of the USFB flooring system, parametric studies are conducted using a finite-element model and five floor spans. The model was first validated against an experimental test conducted by the authors. Emphasis is placed on the fundamental frequency to predict the possibility of resonance of this complex flooring system with typical human-induced dynamic loads in building structures. To further facilitate the practical numerical modelling and vibration analysis of buildings with USFB floors in standard commercial structural software, an analytical method of deriving equivalent isotropic plate properties is developed and its accuracy is numerically verified with regard to detailed Abaqus models.

Purpose - The purpose of this study is to analyze the relationship between Industry-University (I-U) cooperation affecting technology innovation and business performance through combination with R&D human resources, technology capability, and government support targeting global companies.
Design/Methodology/Approach - Based on existing literature, we reviewed factors expected to affect the technology innovation and business performance of global companies and selected I-U cooperation, R&D human resources, technology capability, and government support. The complex relationship between these factors was proposed as a conceptual research model. Data for analysis was from 613 companies among the 2022 survey data of the Ministry of SMEs and Startups. Fuzzy set qualitative comparative analysis was used to analyze the data.
Findings - The I-U cooperation of global companies was found to be a core condition that affects technology innovation. Even if a company does not utilize government support or has poor technology capabilities, I-U cooperation appears to be an important factor in determining technology innovation. In addition, the R&D human resources of global companies were found to be a core condition that determines technology innovation, and the I-U cooperation of global companies was found to be a core condition that affects business performance.
Research Implications - It was revealed that the I-U cooperation of global companies, combined with R&D human resources, technology capability, and government support, is an important factor affecting technology innovation. In addition, it was revealed that the I-U cooperation of global companies is an important factor affecting business performance in combination with R&D human resources, technology capability, government support, and technology innovation.

Authors:   The Korea International Trade Research Institute, Lee Ji-Young , Kwon Han-Jo
Published: May 2024

Purpose - In this study, the main purpose is to elucidate the factors determining the demand for HMR by confirming the purchase demand and selection demand according to the dietary lifestyle and HMR selection attribute factors considered by consumers in the process of selecting HMR.
Design/Methodology/Approach - In order to achieve the above research objectives, the following methods were presented. First, using the truncated Poisson model (TNB), determinants of purchase demand were estimated through selection attribute factors, consumption value factors, demographic characteristics, and HMR usage patterns.
Findings - As a result of estimating purchase demand determinants according to HMR involvement, it was found that safety, convenience, product quality, product promotion, and price rationality had a positive (+) effect in the high-involvement group, and convenience in the low-involvement group. Product quality, product promotion, and price rationality have a positive (+) effect, and it was confirmed that there was a difference between the groups involved based on the verification results through the LR-test.
Research Implications - In HMR, demand determinants may vary depending on various circumstances such as purchase purpose or individual characteristics, so it will be possible to cope with customer demand through selection attribute factors considered by consumers.
Analysis of Determinants of Total Fertility Rate in Asia-Pacific Countries Considering Common Factors Effect
Authors:   The Korea International Trade Research Institute, Kim So-Youn , Ryu Su-Yeol
Published: May 2024

Purpose - This study examines the impact on total fertility rate in 30 countries in the Asia-Pacific region, focusing on female labor market participation and labor market instability.
Design/Methodology/Approach - There is a common factors effect of cross-sectional dependence on the total fertility rate, explanatory variables, and residuals. Therefore, it was estimated using the CS-ARDL (Cross-Sectionally augmented Autoregressive Distributed Lags) model that considers the dynamics of total fertility rate, common factors effect, and heterogeneity by country.
Findings - Female labor market participation and labor market instability have a negative (-) effect on the total fertility rate, but the coefficient of the interaction term is estimated to have a positive (+) sign, so it should be considered in the impact of the labor force participation rate and unemployment rate.
Research Implications - A low female labor force participation rate and unemployment rate drive a high total fertility rate, but countries with a high labor force participation rate should have a high unemployment rate, and countries with a high unemployment rate should have a high labor force participation rate. Therefore, policies are needed to enable women to balance work and family life, and facilitate entry into the labor market.
A Study on Export Trade Efficiency and Potential of Korean Semiconductor Industry: Empirical Evidence from 72 Trade Export Countries
Authors:   The Korea International Trade Research Institute, Li Xiao-Hui , Lee Yang-Kee
Published: May 2024

Purpose - The semiconductor industry is an integral part of the Korean economy. Trade competition in semiconductors, the core component of the fourth industrial revolution, has become increasingly fierce. In this context, this study aims to empirically analyze the current situation, international competitiveness, and challenges faced by Korea’s semiconductor export trade from the perspective of trade efficiency by using Korea’s semiconductor export trade data.
Design/Methodology/Approach - Using a stochastic frontier gravity model, this study analyzes the data of 72 countries and regions that have been the main targets of Korea’s semiconductor exports for the past 22 years using an empirical approach to investigate the main factors affecting Korea’s semiconductor export trade, trade efficiency, and trade potential.
Findings - From the division of semiconductor export market type, there are 13 saturated countries, and the trade volume accounts for 77.86% of the total trade volume of Korea’s semiconductor exports. There were 31, 16, and 12 expansion, development, and iceberg-type countries, respectively. In addition, the regression results show that Korea’s population size and the R&D expenditures of the countries with which it trades have a significantly positive effect on semiconductor exports.
Research Implications - To date, no more systematic empirical research literature on the efficiency of Korean semiconductor export trade has been found, and this study fills the gap in the literature in this area through an empirical analysis approach. This study aims to provide a reference value in Korea’s semiconductor export trade.
Heterogeneous Impacts of the Korea-Japan Trade Dispute on Bilateral Agri-Food Trade
Authors:   The Korea International Trade Research Institute, Min Sunhyung , Cho Sung-Ju
Published: May 2024

Purpose - The purpose of this paper is to provide a rigorous quantitative assessment of the heterogeneous impacts of the Korea-Japan trade dispute on bilateral agri-food trade across different product categories.
Design/Methodology/Approach - Based on a structural gravity model and a difference-in-differences approach, the paper estimates the effects of the dispute on trade flows in both aggregated and disaggregated HS 2-digit product levels. The analysis utilizes annual bilateral trade data from 2017-2022 and monthly data for 2019.
Findings - The findings reveal significant declines in Japanese exports of vegetable products and prepared foodstuffs to Korea, consistent with the theoretical prediction that sectors with higher average consumer animosity would be more negatively affected. However, the results also point to potential trade diversion and substitution effects, as evidenced by the increase in Korean exports of animal/vegetable oils to Japan post-dispute.
Research Implications - The findings have important implications in understanding the complex effects of trade disputes on sensitive sectors like agriculture. These emphasize the need to consider sector-specific dynamics and both short-term and long-term effects when assessing the consequences of trade tensions. The study contributes to the literature on the heterogeneous impacts of trade conflicts, and provides insights for evidence-based policymaking in navigating the global trade landscape.
