Published: March 2024

Interfacial ferroelectricity is a phenomenon arising in a plethora of parallel-stacked layered materials,1-11 in which out-of-plane ferroelectric order is switched by in-plane sliding of adjacent layers.4 Unlike conventional ferroelectrics, interfacial ferroelectricity is stable against doping,7 potentially enabling next-generation devices with storage and computational capabilities.12 However, the field has been limited to indirect sensing or visualizing the ferroelectricity in basic bilayer units employing surface-sensitive probes. In the case of transition metal dichalcogenides, this leaves a void of in-depth knowledge about the influence of ferroelectric order on their intrinsic valley and excitonic properties. Here, we report direct far-field probing of ferroelectricity in few-layer 3R-MoS2 using reflectance contrast spectroscopy. Contrary to a simple electrostatic perception, the intralayer excitons with strictly in-plane dipole orientation are sensitive to out-of-plane ferroelectric ordering. On the other hand, despite possessing an out-of-plane electric dipole component,13 layer-hybridized momentum-indirect excitons remain decoupled from such ordering. Ab initio calculations elucidate the microscopic origin of the correspondence between ferroelectric order and optical response. Using a field-effect device, we demonstrate room temperature control and optical readout of multi-state polarization and its hysteretic switching. Time-resolved Kerr ellipticity measured in different ferroelectric domains reveals a direct correspondence between spin-valley dynamics and ferroelectric order.

Authors: Rabaani Eman Al , Yahyaei Asma Al , Alkasbi Rahaf , Alhashmi Yumna , Hatmi Ibrahim Al
Published: March 2024

This study investigates a comparative analysis of the perceptions of nurses engaged in 8-hour and 12-hour shifts, exploring various dimensions of their professional and personal lives. Conducted in a tertiary hospital in Muscat, Oman, the research investigates the potential impact of shift length on factors such as fatigue levels, quality of life, satisfaction, and safety incidents. While revealing nuanced insights into the advantages and drawbacks of each shift system, the study emphasizes caution in generalizing findings to other medical institutions. Methodological limitations, including the singular hospital focus and the short-term nature of the assessment after the 12-hour shift implementation, are acknowledged. The study calls for future research to expand these insights to diverse contexts and employ longitudinal approaches. Implications for nursing practice underscore the need for informed decision-making by management, considering factors such as nurse well-being, patient safety, and continuity of care. The study contributes valuable insights to the ongoing discourse on nursing shift lengths, emphasizing considerations for both research and practical application.
Schistosoma japonicum complex: relatedness of the parasites and relatedness of its intermediate hosts in evolution
Authors: Nelwan Martin
Published: March 2024

Purpose
In this research, I report the relationship between S. ovuncatum, S. sinensium, S. japonicum, S. mekongi, and S. malayensis. Additionally, I also report the relatedness between five species of Oncomelania and Neotricula aperta, Robertsiella spp, and Tricula spp. Furthermore, I describe the formation of the genus Oncomelania from its predecessor forms.
Principal Results:
The results of nucleotide BLAST showed that S. ovuncatum shared 99.69% identity with S. sinensium, 98.68% identity with S. mekongi, 97.98% identity with S. malayensis, and 97.85% identity with S. japonicum. All E-values are smaller than 0.01. The tree-view slanted cladogram showed that S. sinensium is a sister to S. ovuncatum. It split into S. japonicum. Schistosoma japonicum splits into S. mekongi and S. malayensis. The results also showed that Oncomelania robertsoni shared 86.12% identity with Neotricula aperta, 85.88% identity with Robertsiella spp., and 85.28% identity with Tricula bollingi. The tree-view slanted cladogram showed that Tricula spp. split into N. aperta and Robertsiella spp. This study showed that Oncomelania emerged from its predecessor forms.
Conclusions
Nucleotide BLAST results showed that S. ovuncatum is close to S. sinensium. Schistosoma sinensium split into S. japonicum, S. mekongi, and S. malayensis. Oncomelania robertsoni was closer to N. aperta than to Robertsiella spp. and Tricula spp. (Tricula bollingi). Oncomelania species emerged from their predecessor forms.
Correlating Measures of Hierarchical Structures in Artificial Neural Networks with Their Performance
Authors: Xu Zhuoying , Zhu Yingjun , Hong Binbin , Wu Xinlin , Zhang Jingwen , Zhou Da , Liu Yu
Published: March 2024

This study employs the recently developed Ladderpath approach, within the broader category of Algorithmic Information Theory, which characterizes the hierarchical and nesting relationships among repeating substructures, to explore the structure-function relationship in neural networks. The metric order-rate η, derived from the approach, is a measure of structural orderliness: when η is in the middle range (around 0.5), the structure exhibits the richest hierarchical relationships, corresponding to the highest complexity. We hypothesize that the highest structural complexity correlates with optimal functionality. Our experiments support this hypothesis in several ways: networks with η values in the middle range show superior performance, and the training processes tend to naturally adjust η towards this range; additionally, starting neural networks with η values in this middle range appears to boost performance. Intriguingly, these findings align with observations in other distinct systems, including chemical molecules and protein sequences, hinting at a hidden regularity encapsulated by this theoretical framework.
Nudging interventions on stair use: a scoping review
Authors: Tzikas Alexandros , Koulierakis George , Athanasakis Konstantinos , Merakou Kyriakoula
Published: March 2024

Stair use is a physical activity that can be incorporated into the daily lifestyle of a majority of the population, resulting in several health benefits. Nudges are increasingly used in public health interventions to encourage healthy behaviours such as physical activity in a cost-effective manner. This scoping review aimed to investigate the effect and the characteristics of nudges used on interventions to promote stair use. We reviewed the relevant literature published in PubMed, Cochrane Library, Mendeley & Google Scholar, from January 2009 to May 2022. Eligibility criteria included original studies of any type of design, written in English, targeting healthy adults, reporting nudging interventions, using elevator or escalator as comparators and defining a baseline for comparisons. Initially, 118 publications were identified, and after applying exclusion criteria, 27 articles were included in the analysis. Results showed that most of the nudging interventions had significant positive effect on stair use in several settings. The evidence from this review suggests that incorporating nudges into public health interventions can effectively promote physical activity through increased stair usage. Emphasizing prevention measures in public health interventions may contribute to better health outcomes.

Massless Rarita-Schwinger equations: Half and three halves spin solution
Authors: Valenzuela Mauricio , Zanelli Jorge
Published: March 2024

Counting the degrees of freedom of the massless Rarita-Schwinger theory is revisited using Behrends-Fronsdal projectors. The identification of the gauge invariant part of the vector-spinor is thus straightforward, consisting of spins 1/2 and 3/2. The validity of this statement is supported by the explicit solution found in the standard gamma-traceless gauge. Since the obtained systems are deterministic -free of arbitrary functions of time- we argue that the often-invoked residual gauge symmetry lacks fundamental grounding and should not be used to enforce new external constraints. The result is verified by the total Hamiltonian dynamics. We conclude that eliminating the spin-1/2 mode via the extended Hamiltonian dynamics would be acceptable if the Dirac conjecture was assumed; however, this framework does not accurately describe the original Lagrangian system.

Published: March 2024

Missed and unfinished nursing care in hospitals depends on the quality of human resources. This paper aims to analyze the influence of selected work characteristics on missing and incomplete nursing care in inpatient wards of Czech hospitals. The relationship between the rate of missed and unfinished nursing care and selected work characteristics was studied using the Czech version of the standardized questionnaire, the MISSCARE Survey. The study was conducted from September 26, 2021, to October 15, 2021. Controlled interviews with 1,205 nurses working in ward blocks in Czech hospitals were used. The research results showed statistically significant connections between selected work characteristics and missed and unfinished nursing care. Nurses with the highest level of education (Master, Ph.D.), nurses with specialized education, nurses with the lowest number of working hours (less than 30 hours per week), and nurses with the highest number of years of work experience (21 years and over) show a significantly lower rate of missed nursing care. Nurses from surgical departments, specialist nurses, and nurses with the highest education (Master, Ph.D.) report statistically significantly lower unfinished care levels. In contrast, nurses from regional/district hospitals, practical nurses/nursing assistants, and nurses with the lowest education (secondary school of nursing) report significantly higher unfinished nursing care levels. The information obtained can be used to improve nursing processes in the identified weak parts, strategic planning of nursing care, and sufficient personnel.

Felsőoktatási kihívások és az oktatói jóllét összefüggései egy kvalitatív kutatás tükrében
Authors: Kocsis Zsófia , Hrabéczy Anett
Published: March 2024

A felsőoktatásban végbemenő változások a tömegesedés következtében új kihívások és szerepek elé állították az oktatókat. A korábbi kutatások egyetértenek abban, hogy a felsőoktatási intézmények eredményessége nagy mértékben múlik az oktatók teljesítményén, azonban az ezt elősegítő, jóllétet támogató tényezők vizsgálata eddig kevés figyelmet kapott a szakirodalomban. Kutatásunk célja, hogy megismerjük az oktatók testi-lelki, érzelmi és szociális jóllétének dimenzióit, és feltárjuk azon tényezőket, melyek kihívásként, rizikófaktorként jelennek meg az oktatói munka során. Ennek vizsgálatára félig strukturált fókuszcsoportos interjús kutatást végeztünk, 11 kelet-magyarországi egyetemi oktatót kérdeztünk meg. Legfontosabb eredményeink között említhető, hogy a felsőoktatási intézmények oktatói szerepértelmezése, a munkahelyi jóllét, valamint az egyes szerepekhez kötődő kihívások jelentős tényezőként jelennek meg az oktatók narratíváiban. Eredményeink segítséget jelenthetnek az oktatáspolitikai és intézményi döntéshozóknak abban, hogy megfelelő döntésekkel támogathassák az oktatók jóllétének javítását, ezzel közvetetten elősegítve az oktatói és intézményi kiválóság elérését.

1944/45 telén a nyilasok azokat az 1926 és 1930 között született leventéket mozgósították, akik között jónéhány 15 éves vagy azt még be sem töltött életkorú fiú akadt. Zircen 1945. február 28-án 800 bakonyi leventét tereltek vagonokba, hogy németországi kiképzésre küldjék őket. Rokonai Simon önként vállalkozott arra, hogy elkíséri a fiatalokat, és végig velük marad. Kutatásomban mikrotörténeti megközelítést alkalmaztam, amely lehetőséget ad arra, hogy az egyén és a kisközösség élettapasztalatai kerüljenek előtérbe. A tanulmány a ciszterci szerzetes tanár alakját, személyét az út szenvedéseit átélt leventék visszaemlékezései és Rokonai önéletrajza alapján mutatja be. Abból a kb. másfél évet felölelő időszakból villant fel képeket, amely a zirci indulástól a dortmundi légitámadáson, a németországi bolyongáson át, az amerikai és francia hadifogságon keresztül a hazatérésig tartott. A dolgozatban a pedagógiai helyzetek, a ciszterci szerzetes tanári és papi tevékenysége, emberi helytállása kerül bemutatásra, amely az emlékiratok tartalomelemzéssel történt feldolgozásával tárul az olvasó elé.

The Relationship Between Religious Values and Politics in Türkiye: Research on the Voting Preference of Religious Communities
Authors: YILDIZ Mehmet Mazhar
Published: March 2024

This study investigates the voting preferences of religious communities with a standardized structure in Türkiye. The results of the qualitative research conducted in Diyarbakır with“six” religious congregations that declared that they would support the People's Alliance and “one” religious congregation that declared that they would support the Nation's Alliance before the 2023 elections revealed that religious values are dominant in the vote preferences of religious congregations. However, when we look at the reasons for the emergence of their values, we see that it is not based solely on faith; the religious ideology that emerged as a result of the political traumas caused by the religious policies of the single-party period on the religious community is an important reference point in the vote preference of religious communities. Due to the low number of candidates in an election with two candidates, an understanding of the lesser of two evils was adopted.

Este trabalho aborda o contexto histórico da Guiné-Bissau em conjunto com o desenvolvimento da educação historicamente e as necessidades observadas para uma educação que necessita se consolidar efetivamente como menos colonial no país. Optamos para essa análise utilizar a pesquisa bibliográfica como forma de levantar um debate sobre os referenciais e apresentar as debilidades do sistema educacional guineense, além de, apresentar algumas soluções ao pensamento crítico na educação. Compreendeu-se no desenrolar da discussão, que diversos problemas constituem as debilidades e limitações do sistema de ensino guineense, mas que, entretanto, os problemas não têm origem somente na condição econômica conforme o país é apresentado ao mundo, mas sim, e sobretudo, nas condições coloniais e nos padrões coloniais que fizeram parte do processo histórico de colonização europeia pelo mundo, e que, ainda fazem parte do  pensamento educativo guineense e de boa camada de sua classe política permeados pelo colonialismo mental e as colonialidades do poder, saber e ser.
Benefit of Biodiversity – Polemic View of Environmental, Social and Ethical Aspects of Czech Philosophers and Environmentalists
Authors: Lípa Jan , Rozenský Ladislav , Ondrušák Petr , Dolista Josef
Published: March 2024

This text will deal with the issue of the benefit of biodiversity in the polemic context of the works of Czech and Central European philosophers and environmentalists with the essential ideas of selected world thinkers and with environmental practice in Central Europe. To validate this thesis, the authors of this work chose an essay dealing with professional monographs and professional articles on this topic, focusing on the continuity of ideas of the authors of the Central European region. For the comparison, forestry was used as an exemplary major field. Based on the article, the premise can be accepted that the benefit of biodiversity appears as a basic assumption, thesis, or paradigm. We need a new definition of life that is not limited to carbon-based organisms. Humankind does not live in harmony with nature but uses its culture to deplete natural resources in the false belief that man is no longer a part of nature. Environmentalists and philosophers agree on the need for a turnaround to save the environment, maintaining, biodiversity, and life on Earth. But the predatory paradigm of culture may appear to be a temporary condition and perhaps even necessary to cope with that turn. The effort to preserve biodiversity is related to the effort to preserve the life of the human species. Popularization, or environmental education, leading to biodiversity preservation and development and sustainability of life on Earth should coincide from above and below. Therefore, it could be stated that biodiversity (not only the macroscopic one) is beneficial to sustain life as we know it now.
Uso de un rango de captura limites para determinar capturas totales permisibles.
Authors: Cubillos Luis , Sepúlveda O. Aquíles , Hernández R. Aldo , Miranda A. Leonardo
Published: March 2024

Con el objeto de determinar capturas totales permisibles (CTP), se propone el uso de un rango de capturas definido entre valores mínimos y máximos aceptables. El límite superior (Ymax) debe fijarse sobre la base de criterios biológicos, mientras que criterios sociales y económicos deben ser considerado para fijar el límite inferior (Ymin). El enfoque que se propone con el usode un rango de capturas límites es determinar explícitamente cual es el nivel de captura recomendable según la incertidumbre en la estimación de una CTP, que esté dentro del rango, y que tenga un riesgo dado (probabilidad) de no superar Ymax y un nivel de riesgo calculado que la CTP sea menor que Ymin. De esta manera, cuando la incertidumbre en la estimación de la CTPtiende a ser mayor, la nueva CTP -basada en un nivel de riesgo mínimo aceptado (e.g. 10%) que la CTP actual excederá Ymax-, tenderá a ser más baja y más cercana a Ymin, produciendo un mayor riesgo para la pesquería. Las ventajas del uso de un rango de capturas límites son promover metodologías de evaluación más precisas y exactas para minimizar los riesgos para lapesquería (límite inferior). En otras palabras, para minimizar la presión política, económica y social por aumentar las cuotas anuales de captura.
Ciclo de maduración ovárica, fecundidad y talla de madurez en Macruronus magellanicus (LÓNNBERG, 1907) de la zona Sur de Chile.
Authors: Chong Lay-Son Javier
Published: March 2024

Se realizó un estudio del desarrollo ovárico y fecundidad de M. magellanicus en la zona pesquera del suraustral de Chile entre las latitudes 46° y 56e L.S., para lo cual se obtuvo muestras de las capturas comerciales durante los años 1996 y 1997. El desarrollo gonádico se efectuó mediante histología y examen macroscópico de los ovarios y la fecundidad parcial se efectuó a través del recuento de los ovocitos hidratados mediante la aplicación del método gravimétrico, previa observación de la ausencia de folículos postovulatorios. Se estimó la fecundidad total mediante el contaje de los ovocitos sobre 300 pm en ovarios en estados de madurez avanzada. La talla de madurez sexual se estimó a través del método de la función logística, durante la época de máxima madurez. El examen microscópico, así como el macroscópico, señala que la merluza de cola presenta la modalidad de desovante de grupo sincrónico con un ciclo de maduración que se inicia en mayo alcanza su máximo en julio, seguido de un corto desove en agosto que puede extenderse hasta septiembre. La fecundidad parcial alcanzó un promedio de 243.743 ± 155.557 ovocitos para ejemplares entre 770 g y 2700 g, mientras que la fecundidad relativa considerando la fecundidad parcial entregó un valor promediode 188 ± 83 con rango de 65 a 363 ovocitos.

Authors: Janapureddy Ravindranath , Koffler Yosef , Chew Jowinn , Frings Daniel , Gummuluri Krishna Swetha
Published: March 2024

BACKGROUND

Generalised Anxiety Disorder(GAD) is estimated to affect 1 in 8 people in the UK seeking help from their GP in primary care; where treatment options may either be unacceptable to patients (e.g. medication), or may be delayed (e.g. psychotherapy delivered through NHS Talking Therapy services). These barriers leave an important treatment gap that may be filled by Digital Mental Health Interventions, offering immediate, evidence-based care.

OBJECTIVE

This study aimed to evaluate the efficacy,d user acceptability and safety of the Resony Anxiety app, a digital therapeutic intervention for individuals with self-reported anxiety using a pre-post study design.

METHODS

A total of 86 UK-based participants were recruited and underwent a 6-week intervention using the Resony Anxiety app as a standalone unguided intervention. Primary and secondary outcome measures included the GAD-7 and DASS-21 questionnaires.

RESULTS

The participants reported a significant reduction in anxiety of 3.27 points on the GAD-7 after six weeks, with continued improvement during the follow-up period. The effect size was medium for GAD-7 and small for DASS-21 as measured using Hedge’s g. Qualitative feedback indicated that 95% of participants enjoyed using the app, and 64% found it effective in managing their anxiety. 77% of the participants would recommend the app to a friend or family member with anxiety.

CONCLUSIONS

This study indicates that the Resony Anxiety app is effective and safe in reducing anxiety in adults. Future studies with larger samples and more robust experimental designs, such as randomised controlled trials, are needed to confirm these initial promising findings.

Published: March 2024

Background. The aim of the research was to determine the ultrastructure of the cells of the muscle wall of the mice gallbladder under the influence of ursodeoxycholic acid. Materials and methods. The animals were divided into 2 groups: experimental (n = 17) — mice which received ursodeoxycholic acid at a dose of 100.0 mg/kg and control (n = 13) — intact ones (distilled water). Histological and ultrastructural analyses of gallbladder wall samples of mice were performed. Results. Mitotic figures of myocytes in the wall of the gallbladder bottom (1.794 ± 0.103 %) and body (1.607 ± 0.095 %) in the experimental group of mice were significantly more frequent compared to the controls (0.946 ± 0.058 % and 0.873 ± 0.061 %) (p < 0.01). Enhancing nuclear activity of fibroblasts due to chromatin decondensation and an increase in the number of nuclear pores were observed after the action of ursodeoxycholic acid (0.106 ± 0.007 vs. 0.253 ± 0.018) (p < 0.01). A considerable increase in the number of interstitial cells of Cajal in the muscular membrane of the bottom and body of the gallbladder was noted after the injection of ursodeoxycholic acid (4.61 ± 0.37 mm–2 vs. 2.77 ± 0.23 mm–2) (p < 0.01). Conclusions. Our hypothesis was confirmed by the presence of histological signs of leiomyocyte hyperplasia and an increase in the nuclear activity of fibroblasts in the muscle wall of the mice gallbladder as a result of ursodeoxycholic acid use. Excessive activation of hyperplastic processes of leiomyocytes has an unsettled nature after the injection of ursodeoxycholic acid. An increase in apoptosis of smooth myocytes is observed under the influence of ursodeoxycholic acid. Stimulation of gallbladder wall motility with ursodeoxycholic acid might be associated with an increase in the number of interstitial cells of Cajal in the muscular membrane of the bottom and body of the gallbladder.
A Prediction of Option Price via Two Volatility Computations with Application to a 50ETF Option
Authors: Liu Yueyan , Song Hengrui
Published: March 2024

Financial derivative trading is integral to stock markets, leading to high option price volatility due to increased trading volume. Determining a reasonable option price is complex and requires extensive research in fields like Economics, Applied Mathematics, and Finance Engineering. The Black-Scholes (BS) equation provides a scientific pricing tool for options by considering five parameters: stock price (S), option strike price (K), risk-free interest rate (r), time to expiration (τ), and volatility (σ). Notably, all model parameters except volatility σ can be directly observed from market data, necessitating the determination of this parameter from historical data when applying the BS model in practice.In this report, we examine two widely used computation methods for volatility. The first method involves a simple statistical calculation of historical data, resulting in the historical volatility (HV). The second method utilizes the BS model in a "backward" manner: given any previous option price and four other parameters, we solve the BS equation to obtain the implied volatility (IV). To determine such an IV parameter, we propose a generalized fixed-point iterative solver for solving a complex nonlinear equation. By employing a well-designed initial guess, we demonstrate that this fixed-point solver achieves global and rapid convergence.The two volatilities lead to different predictions of the option price. This report examines if the BS model accurately predicts the option price using these volatilities. It presents an empirical study on a 50ETF option, where we use t-tests to check the hypothesis and determine the relationship between predicted and actual option prices. The study finds that using implied volatility in the BS model provides significantly more accurate predictions compared to historical volatility.

Based on the preliminary research conducted by the researcher, several things were found that became obstacles in the learning process, especially the media/platform used during virtual learning at Politeknik Pelayaran Sumatera Barat. Therefore, the researcher developed a learning management model product based on a web application. It is hoped that it can increase motivation and help the difficulties of cadets who have below average competence to catch up with their friends who have better competence than them. In addition, through this learning management model, it is expected to create an innovative learning management model that is integrated with technology. The ship electrical system learning model was developed from a factual model and adapted to the needs analysis of cadets and lecturers during online learning, then developed to increase cadets' motivation to learn while online. The feasibility level of this application web-based learning model can be seen from the results of the questionnaire given to users, namely lecturers and cadets which show that 88.5% of the ship's electrical system learning management model is feasible to be implemented at Politeknik Pelayaran Sumatera Barat. Learning activities in the ship's electrical system course, this is evidenced by the results of the questionnaire, the cadets’ learning motivation increased by 89%
The Design of FIR Filter Based on improved DA Algorithm and its FPGA implementation: REVIEW
Authors: . Akriti
Published: March 2024

Abstract: This research investigates challenges in employing the Distributed Arithmetic (DA) algorithm for Finite Impulse Response (FIR) filters on Field-Programmable Gate Arrays (FPGAs). Focusing on coefficient representation, it explores precision trade-offs via fixed-point arithmetic and quantization. Memory optimization strategies, such as efficient storage within FPGA resources, are analysed to reduce memory requirements. Enhancing computational speed involves optimizing lookup table access and architectural modifications. Efficient management of FPGA resources and trade-offs between latency, throughput, and resource usage are also explored. Algorithmic refinements specific to DA-based FIR filters are studied to enhance resource utilization and computational efficiency. Overall, this work offers insights and solutions spanning algorithm design, memory utilization, lookup table speed, and FPGA architecture for more efficient DA-based FIR filter implementations on FPGAs.

In the 21st century, Indonesian education must generate life skills for dealing with the era of society 5.0. Bioentrepreneurship skills are one of those needed to achieve the primary goal of society 5.0. However, teaching modules that combine entrepreneurship skills still need to be improved. This research aims to produce project-based learning teaching modules on plant growth and development material to train valid and practical society 5.0 (bioentrepreneurship) era skills. This research used a 4D. The teaching module's validity was determined by the validation results of three experienced lecturers. The practicality of the teaching module was measured based on the results of the readability test. The results of the teaching module validity test obtained an average score of 3.8, which is very valid. The results of the practicality test are reviewed from the textbook readability test, which is categorized as level 12 with a practical category. The results showed that project-based learning teaching modules on plant growth and development material are valid and practical to train the skills of the era of society 5.0 (bioentrepreneurship). Society era 5.0 (bioentrepreneurship) skills students can be trained by integrating plant growth and development biology material with microgreens cultivation project activities in project-based learning modules.
The Invention of Anti-American Sentiment －Why North Korea Shifted the Blame for the Sinchon Massacre to the United States－
Authors: Yea Daeyeol
Published: March 2024

From October to December 1950, a large-scale massacre took place in Sinchon, Hwanghae Province. North Korea dubbed this incident “Sinchon Massacre” and claims that 35,383 people were slaughtered by the US military. In times of external and internal crises, North Korea has recalled the memory of the Sinchon Massacre to stir up anti- American sentiment among its people and achieve regime integration. However, the atrocious crimes of murder, arson, rape, and torture that North Korea attributes to the US military had actually been committed by members of the right-wing peace preservation corps in retaliation for the North Korean regime’s preventive custody measure. Nevertheless, North Korea shifted the blame for the Sinchon Massacre to the US military because there was a need to embrace the members of the base class who had betrayed the regime during the UN occupation of North Korea. To this end, North Korea included the air raids that indiscriminately killed civilians in the scope of “massacre” and named Harrison as the individual ultimately responsible for driving the North Korean people out to the site where they were eventually massacred. Moreover, former members of the peace preservation corps were classified into “active instigators” and “passive participants”－the scope of the former group was minimized, and the latter group was reeducated through home confinement and other forms of social punishment. Yet, the “counterrevolutionary” ideology prevalent in post-war North Korea proved to be an obstacle in achieving regime integration. In particular, it led to animosities and jealousies among members of production facilities, such as cooperative farms and factories, negatively impacting economic reconstruction and productivity growth. In an effort to resolve this issue, North Korea aimed to achieve societal integration and productivity growth by historicizing the Sinchon Massacre and fostering anti-American sentiment. Accordingly, the site of the massacre was transformed into the museum, and the move also served as a subtle warning to the former “hostile elements.”
An Examination of the Koryŏ-Khitan Relations from the 10th to 12th Century through the Balance of Power System
Authors: Heo Inuk
Published: March 2024

International relations in East Asia from the 10th through the 12th centuries had been understood through a triangular relationship framework with the Khitan and the Song in a bipolar relationship and either Koryŏ or Western Xia as the third state. It is widely acknowledged that this framework has the advantage of simplifying international affairs under restricted conditions, which allows for an easy comprehension of the situation at the time. However, even the Song and the Khitan, which were considered to be major powers at the time, were merely two nations among equals. The period spanning the 10th to 12th centuries was not characterized by any single nation overpowering others. Consequently, the countries in East Asia during that time had to seek allies and strive for survival in response to the shifting international landscape. There are difficulties in understanding the international order of that era based solely on triangular relationships.The relationship between Koryŏ and the Khitan also did not lead to a situation where one country overpowered the other. Of course, there is a lot of room to believe that the Khitan has an overall advantage. However, as can be seen from the fact that the Khitans requested reinforcements from the Song to attack Koryŏ, the Khitans were also not confident that they were overpowering Koryŏ. Therefore, rather than confining the relationships among East Asian nations at the time within a rigid triangular framework, understanding the constantly shifting international situations at the time and the fact that all states prioritized their own security would bring us closer to the historical truth.
