В статье рассматриваются современные методы коррекции неоднородности интенсивности, возникающей в процессе магнитно-резонансной визуализации. Неоднородность интенсивности, вызванная различными факторами, значительно усложняет автоматический анализ магнитно-резонансных изображений (МР-изображений). В работе представлены наиболее популярные математические модели, используемые для коррекции данного артефакта, такие как низкочастотная модель, модель гиперповерхности и статистическая модель. Проведен сравнительный анализ этих методов с учетом их эффективности и вычислительной сложности. Полученные результаты могут быть использованы для разработки более точных и надежных методов компьютерной диагностики на основе МР-изображений.
В связи с частым применением метода магнитно-резонансной томографии для клинической диагностики, значительное внимание уделяется автоматическому анализу полученных изображений с использованием методов компьютерного зрения и распознавания образов. При разработке таких инструментов компьютерной диагностики часто встречающейся проблемой является коррекция неоднородности интенсивности на МР-изображениях.
Неоднородность интенсивности возникает в результате влияния таких факторов как неравномерное статическое магнитное поле, вихревой ток, образованный градиентным полем, и неравномерная чувствительность приемной катушки. Данное явление часто называется артефактом МР-изображения, а также известно как поле смещения. Поле смещения представляет собой низкочастотный, гладкий сигнал, который оказывает деструктивное воздействие на МР-изображения и является основным препятствием для обработки изображений и дальнейшей компьютерной диагностики. Для того чтобы исправить поля смещения на МР-изображении необходимо выполнить этап предварительной обработки, в результате которого будет выполнена коррекция неоднородности интенсивности изображения.

Обледенение дорог и тротуаров является одной из актуальных проблем, влияющих на безопасность дорожного движения. В зимний период для борьбы со скользкостью на дорогах и тротуарах часто применяют механический способ удаления льда с их поверхности. Эффективным механическим способом удаления льда с дорог и тротуаров является его разрушение ударным воздействием твердой сферической поверхностью, для чего были разработаны новые рабочие органы. В результате теоретических исследований получены теоретические расчетные зависимости механико-математической модели для определения параметров рабочего органа ударного действия со сферической рабочей поверхностью для разрушения льда, учитывающие характеристики льда, позволяющие проводить инженерные расчеты и определять как на стадии разработки и проектирования, так и в процессе работы, параметры рабочего органа ударного действия со сферическими бойками и подбирать такую величину разрушающего воздействия рабочего органа на лед, при которой возможно разрушить лед заданной прочности и толщины. Разработаны несколько конструктивных решений рабочих органов для разрушения льда на дорогах с регулированием величины разрушающего воздействия на лед изменением радиуса расположения бойка относительно оси вращения рабочего органа, которые за счет возможности адаптации к условиям работы имеют высокую эффективность при разрушении льда и качество очистки дорожных покрытий.

Секция крепи – программно-управляемый робот. Его нагруженность – идентификационный критерий для маневрирования машины и обеспечения устойчивости забоя. Нагруженность как распределение давлений по поверхности его опор и шарниров рычагов, создает напряженно-деформированное состояние системы. Её параметры определяются видом сдвижения кровли. Исследованы особенности расчета давлений на опоры робота в зависимости от расположения шероховатостей от обработки забоя комбайном и распределенных по нормальному закону. Величины давлений зависят от параметров опор и расстояния до забоя. Учтено повышение взаимодействия торцевые частей с шероховатостями кровли, вызывающих их износ и затупление. Предложены новые элементы к системе расчета нагрузок с применением технологии динамического программирования MS Adams.

Priestly Work: God, Creation, and Order
Authors: McGhee Peter , Habets Myk
Published: January 2025

This paper presents the concept of humans as priests of creation and mediators of order, offering a Christian response to ecological challenges. It contests the standard view that Christianity contributes to ecological harm, instead arguing that it provides a framework for stewardship and renewal. Drawing on biblical ideas and theological traditions, the paper views the world as God’s temple, with humanity called to nurture and guide creation, via their priestly vocation, toward its divine purpose. Building on this idea, the paper explores how this priestly vocation can be realized within modern organizations. Practices like sustainability, carbon neutrality, and regenerative industries are reframed as expressions of priestly stewardship and worship. Such an approach emphasizes the interconnectedness of the divine, human systems, and the natural world, advancing a holistic vision of renewal and flourishing.

Published: January 2025

The purpose of this study was to analyze how judgments about self-evaluation(s-e) relate to illusions identified in test score prediction and study strategy judgment situations. Nursing students(N=372) at a community college were surveyed. S-e was measured using a 9-point scale of "I think I am very smart" and ''My friends think I am very smart" to determine the extent of each type. S-e were not related to actual scores, but were positively related to expected scores, which reflected hope and motivation. The "low'' usefulness strategy(u-s), which creates the illusion of fluency and stability, also affects s-e, with direct ratings being positively related to both the use and effectiveness of rereading and the effectiveness of highlighting/ underlining(h/u), and reflective ratings being positively related to the use of rereading. There was no significant correlation with the "high" u-s. When judging learning strategies by predicted score quartiles,(=Q) the ''high'' u-s had higher effectiveness ratings than usage ratings in all Q, and the ''low'' u-s, ''h/u," had higher usage ratings than effectiveness ratings in the 3rd and 4th Q, indicating a typical competence illusion. Only for the ''h/u" strategy was the degree of use significantly higher than the degree of effectiveness when compared to direct evaluation. Overall, the proportion of "direct=reflective" is the highest, with more "dr'', and the proportion of "d=r’' tends to increase with grade level before dropping slightly in the 4th grade. In conclusion, it was confirmed that the illusion of motivation and hope in the test score prediction situation and the fluency and stability illusion in the learning strategy judgment situation are related to the illusion in the s-e situation.

The scientific article will comprehensively study the spiritual heritage of the Alash intelligentsia, who immeasurably went into Kazakh spirituality. The figures of Alash, who appeared on the stage of history with advanced ideas at the beginning of the twentieth century, were able to prove their worth in the political struggle, speaking out against the system established for the freedom and independence of the Kazakh people. Well aware of the viability of their ideas, they sought to educate young people in the national spirit, given that the training of followers of their path is a very important issue.It is necessary to study the valuable historical and spiritual heritage of Alash figures. Among them are works, articles, program positions, comprehensive research and scientific substantiation of the documents that they have implemented, the task of modern scientists. One of the distinctive features of the Alash movement is that it had a massive national character, not limited to a specific region, but encompassing all regions of the Kazakh land, as evidenced by their actions related to these regions. At the same time, such a region of the country as Kyzylzhar played an important role in the fate of Alash figures and made its mark.In this sense, the spiritual heritage of representatives of the Kazakh intelligentsia, who were born in the North Kazakhstan region and actively participated in the Alash movement, working in this region, served as the basis for writing a scientific article

Insights into the real part of natural sea spray aerosol refractive index in the Pacific Ocean
Authors: Fan Chengyi , He Bishuo , Guo Shuqi , Qiu Jie , Zhao Chunsheng
Published: January 2025

Abstract. Sea spray aerosols (SSA) play a pivotal role in influencing radiative effects over oceanic regions, making it essential to accurately quantify their optical properties, particularly the real part of the refractive index (RRI) under varying relative humidity (RH) conditions. This study employs an aerosol optical tweezers (AOT) system coupled with Mie scattering theory to precisely measure the RRI of sea spray aerosols across a range of RH levels. First, standard ammonium sulfate particles were used to validate the AOT measurements against thermodynamic models and previously established parameterizations, confirming the reliability of the optical tweezers’ measurements. Measurements of SSA from offshore and open-sea samples show consistent RRI values, independent of seawater salinity, with artificial sea salt particles effectively representing the optical properties of real SSA at RH > 70 %. A least-squares linear regression scheme linking RRI and RH was developed, allowing for accurate RRI estimation under varying RH conditions. Additionally, our scheme’s intercept at RH = 0 reliably represents the dry-state RRI for sea spray aerosols, validated against standard particles. Results highlight that traditional volume-weighted mixing rules underestimate RRI and aerosol optical depth (AOD), thus reinforcing the need for direct measurement-based parameterizations. This study underscores the importance of accurately representing sea spray aerosols’ radiative properties in climate models. We suggest incorporating the proposed linear regression scheme into aerosol and radiative transfer models to improve model accuracy and enhance the understanding of the effects of sea spray aerosols on radiative processes.

Published: January 2025

Abstract. Closure of the regional sea level budget is investigated over the 2004–2022 time span by comparing trend patterns from the satellite altimetry-based sea level with the sum of contributions, i.e. the thermosteric, halosteric, manometric and GRD (Gravitational, Rotational, and Deformational fingerprints due to past and ongoing land ice melt) components. The thermosteric and halosteric components are based on Argo data. For the manometric component, two approaches are considered: one using GRACE/GRACE-Follow On satellite gravimetry data, and the other using ocean reanalyses-based sterodynamic sea level data corrected for local steric effects. For the latter, six different ocean reanalyses are considered, including two reanalyses that do not assimilate satellite altimetry data. The results show significantly high residuals in the North Atlantic for both approaches. In other regions, small-scale residuals of smaller amplitude are observed and attributed to the finer resolution of altimetry data compared to the coarser resolution of data sets used for the components. Focus on the strong residual signal seen in the North Atlantic suggests Argo-based salinity errors in this region. However, it is not excluded that other factors also contribute to the non-closure of the budget in this region.
Homogeneous ice nucleation in adsorbed water films: A theoretical approach
Authors: Laaksonen Ari , Roudsari Golnaz , Piedehierro Ana A. , Welti André
Published: January 2025

Abstract. Ice nucleation plays a critical role in cloud formation and atmospheric processes, influencing precipitation and climate. In this study, we present a theoretical approach for describing homogeneous ice nucleation within adsorbed water films on insoluble substrates, and suggest that it may be a mechanism for deposition ice nucleation with non-porous ice nuclei that induce ice premelting. Our theory is based on the Frenkel-Halsey-Hill (FHH) adsorption model, which characterizes the substrate-adsorbate interaction, and the classical nucleation theory of homogeneous freezing, which describes the probability of ice formation. We use the theory to model the melting point, critical ice nucleus size, and nucleation rates as functions of adsorbed water film thickness and substrate properties. Our results indicate that the melting point depression can be as much as 5 K on hydrophilic substrates when the thickness of the water film is 1 nm. The onset temperature for homogeneous ice nucleation (235 K for cloud droplets) can shift 1–2 K lower in adsorbed films. At temperatures below 235 K, the humidity at which ice nucleation occurs is determined by the condition that the adsorbed water film must be thick enough to accommodate the critical ice nucleus. Comparisons of calculated relative humidity conditions with experimental ice nucleation data for silica particles show promising agreement, validating the FHH model as a framework for describing deposition ice nucleation in the atmosphere.

Community-Based Rehabilitation (CBR) is a rights-based approach that aims to provide equitable health services and participation opportunities for people with disabilities. Telerehabilitation has emerged as a potential methodology for delivering health care within the CBR framework. However, the accessibility of telerehabilitation presents unique challenges for children with disabilities (CWD) in communities with low socioeconomic status. This phenomenological qualitative study explores the barriers and facilitators that influence the participation of families of CWD in telerehabilitation as a method of CBR in urban poor communities. Nine focus group discussions (FGDs) were conducted involving 75 primary caregivers of CWD. Inductive thematic analysis using NVivo software was employed to analyze the collected data, revealing four themes that impact participation in Telerehabilitation: Economic and Social Resources, Self-Competency Affecting Transition, Flexible Service Delivery Mechanism, and Safety and Security as a Threat to Participation. The findings emphasize the intricate interplay of factors influencing the accessibility of telerehabilitation services for CWD from low-income households. Actionable strategies to address these challenges include providing affordable technology and internet access, offering training and support to families, developing culturally sensitive resources, establishing safety protocols, and advocating for inclusive policies and funding mechanisms. Collaboration among healthcare professionals, policymakers, and families is essential in building a resilient and equitable healthcare system that prioritizes the needs of CWD living in poverty. The insights gained from this study can inform the development of targeted interventions and support systems to ensure that no child is left behind in accessing quality care despite the digital and socioeconomic divides.

This study investigates how effectively telehealth utilization (THU) can substitute for a usual source of care (USC) for taking prescription medication using data from the 2020-2022 National Health Interview Survey. We analyzed data for 69,581 patients. Of these, 5,994 patients (8.6%) lacked a USC. THU was 37.3% for patients with a USC and 15.8% for those without. For patients with no USC or THU, 25.4% had taken a prescription medication within 12 months, while patients with THU but no USC had a rate of 75.4%. In essentially all subgroups, telehealth was associated with substantially higher rates of taking prescription medications. Multivariate logistic regression showed that THU was associated with a 7.39-fold increase (95% CI: 6.19-8.84) in the odds of taking a prescription medication.

Geriatric rehabilitation (GR) facilities are turning to innovative tools such as telerehabilitation to support home-based treatment due to challenges with population ageing, staff shortages, and mounting budgetary pressures. This study identified the potential added value as well as the requirements of using telerehabilitation in home-based GR, according to stakeholders and potential end-users. This exploratory qualitative study design conducted semi-structured interviews among nineteen care professionals, three patients and one informal caregiver. The qualitative data from these interviews were transcribed verbatim and analysed with inductive content analysis. Interviewees indicated multiple added values and requirements for telerehabilitation in home-based GR. Overall, there was great emphasis on blended care implementation,in which telerehabilitation is used in conjunction with in-person care. It is recommended to use the present findings towards developing and implementing a telerehabilitation intervention in home-based GR and assess its feasibility and usability.

While the public health emergency is over, telehealth and telepractice will continue to play a pivotal role in supporting health equity for diverse and vulnerable individuals in underserved communities. The American Occupational Therapy Association, the American Physical Therapy Association, the American Speech-Language-Hearing Association, and the American Telemedicine Association are professional associations representing the interests of more than 564,000 rehabilitation services professionals in the United States. These organizations have shared priorities including legislative, regulatory, and state-based advocacy efforts. Continued advocacy and promotion by professional organizations, providers and patients alike is necessary to ensure that all rehabilitation providers are included in any telehealth lists of federally and state approved providers. In addition, key health care industry stakeholders want telehealth to be a permanent option for care delivery and ensure that telehealth will remain widely available to support health equity and access to critical rehabilitation services for all.

The application of the accident risk assessment methodology, which is the most
effective way to predict accidents, is considered. The accident risk assessment takes into
account not only the accidents that have occurred in the industry, but also the dangers, the
probability of which is very high. Analysis of modern accidents at a hazardous production facility
has shown that when designing an object, all adverse events that can be identified during
its operation are not taken into account, for example, climate conditions, the location of the
object, the use of outdated technologies, qualification and psychophysiological requirements
for personnel are not taken into account. As the analysis of the causes of accidents at hazardous
production facilities has shown, it is necessary not only to find «weak links» in technological
chains, but also to predict how events caused by an accident at a hazardous production facility
will develop, indicate how to reduce their consequences. The article presents the results
of the application of the methodology for determining the criteria for assessing the degree of
risk and checklists in the field of industrial safety at the facility.
Auswirkungen aus der Überarbeitung der Produkthaftungsrichtlinie der Europäischen Union
Authors:   Korean Civil Law Association, Park Shin-Uk
Published: January 2025

Fortschritte und Innovationen in Wissenschaft und Technologie erzwingen vielfältige Veränderungen in unserer Gesellschaft. In diesem Beitrag wird zunächst die Frage gestellt, ob Korea sensibel auf diese Veränderungen reagiert. In Korea, wo immer noch das 1958 geschaffene koreanische BGB gilt, lässt sich diese Frage zumindest im Bereich des Zivilrechts nicht positiv beantworten. Wie in The Brussels Effect von Prof. Anu Bradford zu sehen ist, ist EU unabhängig davon, ob die Reaktionen positiv oder negativ sind, reagiert im Gegensatz zu Korea aktiv auf diese Veränderungen, und eine dieser Veränderungen ist die schnelle Gesetzgebung, z.B. DMA, DSA, KI-Verordnung. In diesem Zusammenhang sind auch die neuen Produkthaftungsrichtlinien von 2024 zu verstehen.
In diesem Beitrag wird diese gesetzgeberische Reaktion im Rahmen der EU vorgestellt und analysiert. Darauf aufbauend wird geprüft, ob eine Revision des Produkthaftungsgesetzes, die zu grundlegenden Änderungen im Zivilrechtssystem führen könnte, auch in Korea notwendig ist. Meines Erachtens muss Korea ebenso wie EU auf Veränderungen in Wissenschaft und Technologie reagieren, und dafür ist eine Überarbeitung des Produkthaftungsgesetzes unerlässlich. Darüber hinaus sollten die folgenden Punkte während der Überarbeitung berücksichtigt werden. Erstens wurde das Gesetz in EU trotz der Kritik am Einsatz von Trilog schnell überarbeitet. Auch Korea sollte versuchen, seine Gesetze zügig zu überarbeiten. Zweitens bedeutet eine gesetzgeberische Reaktion nicht unbedingt einen radikalen Wandel. Eine Form des Produkthaftungsgesetzes kann auch in der modernen Gesellschaft wirksam sein.
Drittens sollte die Einführung des Systems der Offenlegung von Beweismitteln und des Systems, das die Beweislast durch den Nachweis der Wahrscheinlichkeit erfüllt, ernsthaft in Erwägung gezogen werden.
Non discrimination and the legal capacity of a ward under limited guardianship in Korea
Authors:   Korean Civil Law Association, PARK Inhwan
Published: January 2025

The Korean Supreme Court held that the post office's restriction of the financial transactions using CDs, ATMs, and debit cards of a person under the limited guardianship and requiring the limited guardian and the person under limited guardianship together to visit a teller to make the transactions for which the family court ordered that the limited guardian's consent be required, discriminated against persons with disabilities.
A person under limited guardianship is competent to act except for those matters for which the family court has determined that the consent of the limited guardian is required. If the court decides that a person under the limited guardianship should have the consent of the limited guardian, and person under the limited guardianship's acts without the consent of the limited guardian, it is interpreted that the limited guardian without representation can naturally exercise the right of revocation.
However, not only does Article 140 of the Civil Code provide that only the principal and only his or her successor or representative can exercise the right of revocation, but the exercise of the right of revocation by the limited guardian restricts the legal capacity of a person under the limited guardianship, which is contrary to Article 12 of the Convention on the Rights of Persons with Disabilities.
The Convention on the Rights of Persons with Disabilities requires that all persons with disabilities be recognised for the enjoyment of their legal capacity and that measures be taken to support their decision-making in order to enable them to exercise it. I argue that the right of revocation should not be granted to a limited guardian and that it is sufficient to support decision-making, including the exercise of the right of revocation by the person under the limited guardianship.
Furthermore, while the targeted judgement referred to the Post Office's failure to allow financial transactions using CDs, ATMs and debit cards as discriminatory, the failure to have a system in place to enable such non-face-to-face transactions constitutes a failure to make a reasonable accommodation to eliminate discrimination against persons with disabilities. it is also discriminatory not to provide the necessary measure of supported decision making to enable a person with disabilities to exercise their legal capacity in financial transactions. The latter can be a more serious violation in that it can be a matter of discrimination against the right to freedom and the right to equality.

프랑스에서 펜데믹은 기술적 뒤처짐에 대해 인식하도록 했으며, 또한 그 정부에게 이러한 뒤처짐을 따라잡기 위해 최선을 다하도록 부추기는 역할을 하였다. 따라서 프랑스의 재판절차는 코로나와 그로 인한 결과에 대해 약간의 영향을 받게 되었다. 실제로는 재판절차의 디지털화(전자화)는 펜데믹 이전부터 시작되어 계속하여 발전하고 있다. 프랑스의 재판절차는 적어도 부분적으로 탈물질화되어 디지털화되었다. 세 가지 주요 경향이 프랑스 재판절차의 전자화를 특징적으로 보여준다.
첫 전자화 초기 모습(버전)은 오늘날 더 현대적인 기술에 의해 대체되거나 또는 공존하고 있다. 가장 최신 버전은 플랫폼에 맞게 조정되었으며, 이는 정보 사회에서 네트워크와 경쟁하는 형태이다. 초기 디지털화는 서면 소송과 관련이 있었으며, 이는 서면 문서만 디지털화할 수 있었으며 소송 당사자와 변호사는 디지털화할 수 없었기 때문이다. 그러나 개혁의 과정에서, 구두 소송의 디지털화도 시행될 수 있게 되었다. 프랑스 재판절차는 일반적인 소송 규정을 강조하면서 디지털화를 회피하지 않는 우호적 방법에 점점 그 여지를 더 많이 남기고 있다. 민사전자재판은 부인할 수 없는 개선점을 가져왔다. 그러나 디지털화는 최소한 더 효율적이고 만족스럽게 개선되어야 한다.
