Published: March 2024

The aim of this research is to find out the profile or general picture regarding the use of Instagram which is currently popular among teenage students, as well as reducing the level of dependence experienced by teenage students. In this study, the approach used is quantitative with descriptive methods. Sampling was used by random sampling with a total sample of 106 students from one class X Mechatronics department at SMK Negeri 2 Cimahi. The aim of this research is to determine the profile of Instagram dependence among students. There are aspects that are the basis for knowing Instagram dependence, including 4 aspects, namely, Tolerance, Mood Modification, Replase, Conflict. Data collection techniques by conducting an instrument distribution in the form of a questionnaire to students who are the research sample. The research results show that students with Instagram dependence in class X mechatronics are in the High category 15%, Low category 16%, and in the Medium category 69%. After knowing the level of dependence on Instagram among students, the next step is to design programs and provide services based on the results of this research. In providing services, students are directed to carry out interviews to find out whether the services provided are acceptable to students and whether students experience a decrease in their use of Instagram. The next step is to give the posttest to students again so that a comparison can be carried out, so that it can be seen that H0 is rejected and H1 is accepted so that it can be concluded that the group guidance service is declared effective
Intra-arterial CECT of the Distal Forelimb in Jeju horses: Evaluating CE Factors
Authors: Lee Seyoung , Shin Kwang-Yun , Lee Kija , Seo Jong-pil
Published: March 2024

Background: Few studies have investigated the adequate contrast
enhancement (CE) evaluation depending on concentration, volume, and rate
of contrast media (CM) and the scan parameters in equine contrast
enhanced computed tomography (CECT). Objectives: We
investigated CE of the deep digital flexor tendon (DDFT) and arteries
depending on voltage, concentration, volume, and rate of CM during
intra-arterial CECT of equine distal forelimbs. Study design:
This is a prospective study. Methods: Six horses underwent
fifty-four CT scans. First, the CE of DDFT and arteries was evaluated
depending on the voltage (80 or 120 kV) and CM concentration (150, 120,
or 90 mg I/mL in 50 mL of CM). Second, CE of DDFT and vessels was
evaluated depending on the CM volume (50, 100, or 150 mL) and
administration rate (2, 4, or 6 mL/s) with a fixed iodine delivery rate
(IDR) (300 or 180 mg I/s). Results: CE of DDFT significantly
increased at 80 kV of voltage and 150 mg I/mL of CM concentration
(Median: 29.65; IQR: 1.74; P < 0.05). CE of the DDFT
positively correlated with CM concentration (P = 0.0004; r = 0.75). At
180 mg I/s of IDR, an increase in rate and volume (6 mL/s and 150 mL)
led to low contrast attenuation in the medial and lateral palmar
arteries (median and IQR: 985.93 and 71.8 Hounsfield units [HU] and
988.73 and 41.16 HU, respectively); the CE was sufficient to distinguish
the artery from the adjacent structures. Main limitations: The
number of animals was small for parametric statistical analysis.
Conclusions: Our results suggest that a low CM concentration
could yield sufficient CE of the DDFT and arteries with adjusted CT
scanning parameters or volume and injection rate of CM.
Biomechanical characteristics of equine metacarpophalangeal joint. A review article.
Authors: Grzeskowiak Remigiusz M. , T Michael LaCour , Adair Steve
Published: March 2024

The metacarpophalangeal joint (MCPJ) is a high-motion joint subjected to
substantial loads and elastic work during locomotion. Elastic strain
energy is stored in the flexor tendons and suspensory apparatus during
joint hyperextension and released during the push-off phase. These
complex biomechanical characteristics predispose the joint structures to
injuries such as subchondral bone injury, progressive osteoarthritis,
and fractures, often linked to chronic fatigue from repetitive loading
at the third metacarpal bone and proximal phalanx articulation. In
horses, the MCPJ is commonly affected by osteoarthritis (OA). Several
studies have focused on researching MCPJ mechanics and its relationship
with OA. This review discusses leading advancements in the field of MCPJ
biomechanics, emphasizing their clinical relevance in understanding
osteoarthritis pathophysiology. Joint biomechanics evaluation includes
kinematics and kinetics analysis. Kinematics are analyzed through the
recorded trajectory of reflective markers attached to the distal limb,
registered by a motion capture system. The trajectory data are then
analyzed by the software for subsequent kinetic analysis. To calculate
joint reaction forces, detailed activity of the muscles and ligaments
directly impacting the MCPJ has been evaluated. As a high-motion joint
with elastic properties during locomotion, the MCPJ experiences
significant loads that create substantial pressure on articular
cartilage and stress on surrounding bones. This review provides insights
into the most recent concepts of stress distribution across bones and
articular cartilage proposed to explain and enhance the understanding of
injuries to joint structures.
Multidimensional Hydrodynamic Framework for Modeling Compound Inundation in Coastal Watersheds
Authors: Bayer Logan , Santiago-Collazo Felix
Published: March 2024

We developed a coupled overland and river model for modeling compound
flooding using the kinematic wave approximation on inland sections of an
unstructured mesh, and the diffusive wave approximation on riverine
sections. A finite element method is used for spatial discretization and
a Crank-Nicolson scheme is used for time discretization. A wetting and
drying algorithm is implemented for improved efficiency in the model.
Pluvial conditions and tidal conditions are implemented as source terms
in the river model. The results show that effects from compound
inundation could be captured using this framework.
Kinematic characteristics and water mass transports of submesoscale coherent vortices in the northeastern South China Sea
Authors: Wei Yi , Zhang Zhiwei , Zhang Xincheng , Sun Zhongbin , Zhao Wei , Tian Jiwei
Published: March 2024

As a unique phenomenon occurring in the subsurface ocean, submesoscale
coherent vortices (SCVs) are believed to have a pivotal role in the
long-distance ocean tracer transports. SCVs have been widely observed in
the global oceans, however, most of them are captured accidentally and
their kinematic characteristics and water mass transports have only been
studied in a limited number of regions. Here, we use 4-year observations
of velocity, temperature, and salinity from five moorings in the
northeastern South China Sea (NESCS) to examine dozens of newly
discovered SCVs. A total of 34 SCVs were identified during the
observational period, including 25 convex lens-like anticyclones and 9
concave lens-like cyclones. The maximum swirl velocity, mean radius, and
vertical length scale of the anticyclones (cyclones) are 0.19±0.07 m
s–1 (0.19±0.07 m s–1), 26.4±13.9 km (17.0±5.4 km), and 204±62 m
(188±53 m), respectively. Vertically, the velocity structure of the
observed SCVs conforms to a Gaussian function when the effect of
stratification is removed. Water mass analyses suggest that 88% (30/34)
of the SCVs carried Kuroshio water, which demonstrates the mechanism
proposed by Zhang et al. (2022) that they are formed by Kuroshio-islands
interactions within the Luzon Strait. This category of SCVs is therefore
named Luzon Strait island wake eddies (Liddies). We further estimate
that Liddies can result in an equivalent annual-mean volume transport of
0.20 Sv westward across the Luzon Strait, which suggests that they play
a nonnegligible role in the subsurface water transports between the
NESCS and the northwestern Pacific.
Using ambient seismic noise to monitor ocean bottom pressure
Authors: Luo Bingxu , Zhang Shuo , Takeuchi Nozomu , Lumley David , Zhu Hejun
Published: March 2024

Ambient seismic noise (ASN) recorded by ocean bottom seismometers allows
us to perform coda wave interferometry without using active sources. We
analyzed two-year ASN recordings from five ocean bottom stations in the
northwestern Pacific Ocean basin (depth > 5,500 m), and
measured the relative velocity variation (δv/v)
near the seafloor. The most important finding is an extremely low
variation in δv/v (around
-0.05\%), which likely responds to a significant
pressure drop at sea level and subsequently affects an anomaly at the
ocean bottom (over -400 Pa) in December 2013. Furthermore, several major
phases of the velocity change show delayed-correlation with the sea
level pressure variations. A poroelastic simulation with adjusted ocean
bottom variables supports the pressure factor mainly drives the
variation in δv/v. Our study suggests the
potential use of seismic signals to monitor oceanic and atmospheric
processes by tracking variations in the oceanic pressure field.
Geostatistical Inversion for Subsurface Characterization Using Stein Variational Gradient Descent with Autoencoder Neural Network: An Application to Geologic Carbon Sequestration
Authors: Liu Mingliang , Grana Dario , Mukerji Tapan
Published: March 2024

Geophysical subsurface characterization plays a key role in the success
of geologic carbon sequestration (GCS). While deterministic inversion
methods are commonly used due to their computational efficiency, they
often fail to adequately quantify the model uncertainty, which is
essential for informed decision-making and risk mitigation in GCS
projects. In this study, we propose the SVGD-AE method, a novel
geostatistical inversion approach that integrates geophysical data with
prior geological knowledge to estimate subsurface properties. SVGD-AE
combines Stein Variational Gradient Descent (SVGD) for sampling
high-dimensional distributions with an autoencoder (AE) neural network
for re-parameterizing reservoir models, aiming to accurately preserve
geostatistical characteristics of reservoir models derived from
geological priors. Through two synthetic examples, we demonstrate that
the SVGD-AE method outperforms traditional probabilistic methods,
particularly in inverse problems with complex posterior distributions.
Then, we apply SVGD-AE to the Illinois Basin - Decatur Project (IBDP), a
large-scale CO2 storage initiative in Decatur, Illinois, USA. The
resulting petrophysical models with quantified uncertainty enhance our
understanding of subsurface properties and have broad implications for
the feasibility, decision making, and long-term safety of CO2 storage at
the IBDP.
Linking future precipitation changes to weather features in CESM2-LE
Authors: Konstali Kjersti , Spengler Thomas , Spensberger Clemens , Sorteberg Asgeir
Published: March 2024

Weather features, such as extratropical cyclones, atmospheric rivers
(ARs), and fronts, contribute to substantial amounts of precipitation
globally and are associated with different precipitation
characteristics. However, future changes as well as the representation
of the precipitation characteristics associated with these weather
features in climate models remain uncertain. We attribute 6-hourly
accumulated precipitation and cyclones, moisture transport axes (AR-like
features), fronts, and cold air outbreaks, and the combinations thereof
in 10 ensemble members of the CESM2-LE between 1950 and 2100 under the
SSP3-7.0 scenario. We find that, despite some biases in both
precipitation and weather features, CESM2-LE adeptly represents the
precipitation characteristics associated with the different combinations
of weather features. The combinations of weather features that
contribute most to precipitation in the present climate also contribute
the most to future changes, both due to changes in intensity as well as
frequency. While the increase in precipitation intensity dominates the
overall response for total precipitation in the storm track regions, the
precipitation intensity for the individual weather features does not
necessarily change significantly. Instead, approximately half of the
increase in precipitation intensity in the storm track regions can be
attributed to a higher occurrence of the more intensely precipitating
combinations of weather features, such as the co-occurrence of
extratropical cyclones, fronts, and moisture transport axes.
Peri-Capsular Nerve Group Blocks in the Emergency Department (ED) - A Broad Overview
Authors: S Bhattaram
Published: March 2024

Hip fractures and related conditions present significant challenges in emergency departments (EDs, necessitating effective pain management for diagnostic evaluations and immediate interventions. The Pericapsular Nerve Group (PENG) block, a recent innovation in regional anesthesia, has gained prominence for its profound impact on pain control in hip fractures. This article comprehensively reviews the evolution, anatomy, and applications of PENG blocks in emergency medicine. PENG blocks offer precise, sensory-focused pain relief, crucial for patients experiencing severe acute pain due to hip fractures. By comprehensively targeting articular branches of the femoral, obturator, and accessory obturator nerves with a single injection, PENG blocks preserve motor function and reduce reliance on systemic opioids, leading to more comfortable reductions of hip dislocations and improved patient experiences. The PENG block emerges as a valuable asset in revolutionizing pain management for hip fractures within emergency departments, aligning with the overarching goal of enhancing patient care and well-being. As healthcare confronts the challenges of patient comfort and the opioid crisis, further research, including Randomized Controlled Trials and comprehensive Metaanalyses, is warranted to establish definitive recommendations for ED practices in this domain.

Published: March 2024

Precision Medicine and Precision Public Health are approaches to improve population health. Achieving these goals requires innovation in health informatics. The Centre for Health Informatics (CHI) within the Cumming School of Medicine (CSM) at the University of Calgary (UC), Canada, was created to respond to this need by fostering multidisciplinary collaborations, building capacity by recruiting and training outstanding faculty and students, and harnessing Alberta's rich health data to advance health informatics. To establish CHI as a health informatics leader, CHI has struck partnerships with stakeholders, including Alberta Health Services (AHS), Alberta Health (AH), and the Alberta Strategy for Patient-Oriented Research Unit (AbSPORU) among others. Through these close relationships, the CHI intake team facilitates access to Alberta's rich health data sources and educates researchers on the available health data in Alberta. The concept of a "One Stop Shop" for CSM and UC researchers encourages multidisciplinary collaboration, helps investigators access a wide range of datasets, and receive analytical support. Population-based data sets enable the development of methods to turn raw data into health information, improve health data collection, linkage, analysis, and quality, and applied studies creating clinical decision-support tools, prognostic tools, improved health surveillance methods, and health system performance indicators. CHI's ecosystem of diverse research expertise, cutting-edge technology, and embedded AHS analysts to support data access via a wide-ranging network of partnerships allows our provincial researchers, national and international collaborators tremendous opportunities for empirical research. It paves the way for implementing Precision Medicine in the real world.

“Is Victory a Foregone Conclusion?”: The Ratio of the Military and Diplomatic Efforts of the Bolsheviks in Eastern Russia in 1920
Authors:   Irkutsk National Research Technical University, Vorontsov Denis V.
Published: March 2024

The factual material of the Civil War of 1917–1922 provides grounds for important conclusions. At the same time, propaganda and historiographical inertia pose certain difficulties. The article compares the statements of the Bolshevik leadership with the observance of the real chronology and the indication of the causes of events, shows the complementary combination of combat efforts and diplomatic maneuvers of the Reds. It is empha-sized that the rapid advance of the Red Army deep into Siberia at the turn of 1919–1920, along with the occu-pation of the Kuban by the spring of 1920, became the largest military achievement of the Bolsheviks. At the same time, the successes in the east of Russia created the danger of a clash between the Red Army and Japa-nese troops. The Bolsheviks were forced to show great political flexibility here, proclaiming a formally inde-pendent and democratic Far Eastern Republic. The task was set to quickly create combat-ready troops – the People’s Revolutionary Army, whose basis was the partisans and some of the former Kolchak people. The change of moods of the Siberian peasantry is shown, the sequence and scale of its anti-Bolshevik actions are considered. Conclusion dwells upon the fact that a set of events in 1920 challenged the universality of the class approach.

In this article, based on the historical and cognitive analysis of the artistic heritage of political exiles (XIX–XX centuries), who influenced the formation of intellectual history and culture of Yakutia, symbolic images associ-ated with the North as the “periphery” of the Russian Empire are revealed. In the mental mapping of artistic space, positive and negative images constructed on the basis of the “supporting metaphor” – Cold – are high-lighted. It is concluded that this concept of Cold influenced the formation of the main metaphorical image of Yakutia as the “edge of the earth” and created a layer of various concepts, knowledge, associations and experi-ences consisting of conceptual and value-symbolic components. It has been revealed that depending on the emotional and sensory perception of the surrounding space, one can observe the transformation of the mental image of the North. The collective image of the North includes many elements that allow us to present it as a mythologeme, and on the other hand, to consider the variations of the mentality of an exile forced to be in a completely alien world. Thus, despite the fact that imperial policy actively promoted the image of the North as an exotic and rich land, the “narrative of captivity” imposed on the works of political exiles transmits the image of the space of exile associated with the North as a “land of suffering” and “trials”.

The article delves into the analysis of the broadcasting function of the excursion, considered within the frame-work of an interdisciplinary approach as a cultural narrative. The relevance of the study is due to the expansion of the functions of the excursion beyond the scope of educational and outreach activities. As part of the narra-tive approach, the excursion acts as a broadcaster of historical and cultural memory based on a specially con-structed narrative. Research methodology is based on the peculiarities of the nature of narration in the context of A. Toynbee’s concept of “narrative history”. The understanding of history proposed in this concept as a com-pleted process that needs interpretation brings the excursion story closer to the narrative. The work analyzes the main views on the essence of excursion and narrative, which allows to draw a conclusion about their related nature, as well as to derive a special excursion narrative, understood as a narrative consisting of a number of sequentially presented historical facts and events and their interpretations on the basis of political, cultural, economic, educational and other contexts. It is emphasized that the broadcasting function of an excursion as a narrative is manifested in the possibility of immersion in a certain era or event, contact with the past, and its comprehension.
Philosophical Thought’s Dialectical Movement: The Genesis of the Knowledge System in Alexander Kojève’s Philosophy. Article one: Dialectic and Dedogmatisation
Authors:   Russian State University for the Humanities, Dorofeyev Yakov S.
Published: March 2024

This work explores the main outline of the historical and philosophical conception of the French neo-Hegelian Alexandre Kojève, which is positioned within the Knowledge System as the culmination of sequential dialectics of philosophical discourse, concluded in the Hegelian philosophy. This representation is found in A. Kojève’s “Essai d’une histoire raisonnée de la philosophie païenne”, which is not only an analysis of ancient thought, going back to G. Hegel’s “Lectures on the History of Philosophy”, but also the author’s interpretation of the ge-nealogy of philosophical thought as such. After a series of incomplete resolutions of discursive antitheses by two philosophical doctrines in different historical periods the decisive role is attributed to I. Kant, whose philo-sophical system is a product, according to A. Kojève, of Judeo-Christianity and is its paradigmatic exponent. By crossing the eternal and the temporal through the dogma of the Incarnation, Christianity not only contributed to the emergence of Modern science, but also provided the opportunity for the emergence of Kantian philosophy, which established a “Christian” balance between the Lord and the Bondsman. Heterogeneous discursive com-ponents opposed ancient philosophical doctrines, thereby preparing the necessary ground for their merger, as well as for transforming oneself in this way into a Knowledge System. The research consists of two parts pub-lished in two separate articles. The first part is devoted to the beginning of the analysis of the Knowledge Sys-tem’s genesis in the context of A. Kojève’s historical-philosophical concept.

Tarihî süreç içerisinde oldukça fazla sayıda çatışma yaşayan Türk ve Rus yönetimleri 2000’li yıllardan itibaren çatışmadan uzak bir ilişki ağı geliştirmişlerdir. Her ilişkinin sahip olduğu tarihî geçmiş muhakkak ki geleceğine tesir etmektedir. Bu tesirin olumlu yönde olması adına hem Rus hem de Türk yetkililer 2000’li yıllardan itibaren büyük çaba sarf etmektedirler. İlişkilerini çatışma ve rekabetten uzak bir şekilde işbirliği ve ortaklık temeli üzerinde ilerleten iki ülke uzlaşmazlıklarını ana gündem maddesi yapmaktan uzak bir tavır sergilemişlerdir. Geçmişteki çatışmaların üzerine inşa edilen soğuk ilişkiler ağına rağmen günümüze kadar uzanan kapsamlı ve sıcak ilişkilerin hangi konular üzerinden nasıl var edildiği ise şüphesiz önem arz etmektedir. Bu çalışma içerisinde de Türkiye ile Rusya’nın günümüze kadar uzanan bu sıcak ilişki ağının temelini teşkil eden 2000-2008 yılları arasındaki gelişmeler ele alınarak incelenmektedir.

Kawasan Indo Pasifik menjadi penyumbang sampah plastik laut terbesar dunia. Sampah plastik ini terbawa aliran sungai besar negara Asia Tenggara yang kemudian membendung di Samudera Hindia dan Pasifik. Permasalahan sampah plastik laut cukup kompleks karena menyebabkan kerusakan lingkungan, dampak ekonomi, penurunan kesehatan biota laut, dan mengancam kesehatan manusia yang mengonsumsi. Jepang dan ASEAN bekerjasama untuk mengatasi masalah ini dalam salah satu proyek Joint Statement Japan Cooperation on ASEAN Outlook on the Indo Pacific (AOIP). Penelitian ini berfokus pada kerjasama Jepang dan ASEAN dalam mengatasi sampah plastik laut (Plastic Marine Debris) dalam teori kerjasama keamanan maritim dan Regional Security Complex. Penelitian ini menggunakan metode kualitatif dengan tipe penelitian deskriptif yang menghasilkan kerjasama Jepang-ASEAN berupa pelatihan, pengelolaan limbah, promosi penanggulangan sampah laut, koordinasi berbagai pihak, dan aksi kolaborasi UNEP. Kerjasama ini melahirkan penguatan kesadaran, edukasi, dan (amity) Jepang-ASEAN yang mendukung keamanan maritim dan ekonomi kawasan Indo Pasifik. The Indo Pacific region is the world's larger contributor to marine plastic debris. This plastic waste is carried by the flow of large rivers of Southeast Asian countries which then stem in the Indian and Pacific Oceans. The problem of marine plastic debris is quite complex because it causes environmental damage, economic impact, decreases the health of maritime biota, and threatens the health of humans who consume. Japan and ASEAN are working together to address this issue in one of the Joint Statement Japan Cooperation on ASEAN Outlook on the Indo Pacific (AOIP) projects. This research focuses on Japan and ASEAN cooperation in overcoming plastic marine debris in the theory of maritime security cooperation and Regional Security Complex. This research uses qualitative methods with descriptive research types that result in Japan-ASEAN cooperation in athe form of training, waste management, promotion of marine debris prevention, coordination of various parties, and UNEP collaborative actions. This cooperation resulted in the strengthening of Japan-ASEAN awareness, education, and (amity) that supports the maritime and economic security of the Indo Pacific region.

Introduction: Atrial fibrillation (AF) is an arrhythmia that has a well-established impact on cardiovascular and cerebrovascular morbidity and mortality. However, the role of this arrhythmia plays on surgical risk remains uncertain. Objective: to evaluate the impact of preoperative persistent or permanent AF on in-hospital mortality after isolated coronary artery bypass graft surgery (CABG). Methods: prospective cohort with 2,377 patients submitted to isolated CABG between January 2014 and December 2021. Sixty-two variables, including baseline factors, operative characteristics, and outcomes, were analyzed. Patients were divided into two study groups: No preoperative AF (n=2,287) and preoperative persistent or permanent AF (N=90). The comparison between the groups was performed initially by descriptive and univariate analysis. Subsequently, the analysis of mortality predictors was performed using binary logistic regression - multivariate adjusted analysis. Results: patients with preoperative AF were older, had a higher prevalence of pulmonary hypertension and anemia, had lower ejection fraction and had higher surgical risk scores when compared with patients with no history of atrial fibrillation. The in-hospital death was more frequent in patients with a history of AF (3.2% vs 8.9%, P=0.010). Through the multivariate analysis, it was possible to verify that preoperative AF is independently associated with the occurrence of in-hospital mortality after CABG (OR 2.68; 95% CI 1.21-5.94, P=0.015). Conclusion: Preoperative persistent or permanent AF has been shown to have a significant impact on in-hospital mortality rates after CABG even after adjusted multivariate analysis, being an independent risk predictor for the occurrence of postoperative death.
Los procedimientos históricos de restauración cerámica en el Museo de La Plata

Published: March 2024

El hombre siempre ha sentido la necesidad de restaurar sus objetos. Las distintas sociedades en sus diferentes épocas han establecido diversas soluciones de restauración y los criterios que usaron para ello siempre estuvieron relacionados con los valores que se le atribuían a los bienes e indirectamente, con las ideas políticas, religiosas, estéticas y económicas de cada momento (Lastras Pérez, 2007). En el presente trabajo revisaremos y compararemos los distintos métodos y criterios que se tuvieron en cuenta entre fines del siglo XIX y la actualidad, en el tratamiento de restauración de las piezas de cerámica arqueológica que forman parte de las colecciones del Museo de La Plata (MLP).
