Authors: Li Yue , Wang Liang-Hong , Zeng Huan , Zhao Yan , Lu Yao-Qiong , Zhang Tian-Ying , Luo Hai-Bin , Tang Feng
Published: February 2025

BACKGROUND

A psychological sense of coherence (SOC) in percutaneous coronary intervention (PCI) patients is important for disease prognosis, and there is considerable variation between their symptoms. In contrast, network analysis provides a new approach to gaining insight into the complex nature of symptoms and symptom clusters and identifying core symptoms.

AIM

To explore the psychological coherence of symptoms experienced by PCI patients, we aim to analyze differences in their associated factors and employ network analysis to characterize the symptom networks.

METHODS

A total of 472 patients who underwent PCI were selected for a cross-sectional study. The objective was to investigate the association between general patient demographics, medical coping styles, perceived stress status, and symptoms of psychological coherence. Data analysis was conducted using a linear regression model and a network model to visualize psychological coherence and calculate a centrality index.

RESULTS

Post-PCI patients exhibited low levels of psychological coherence, which correlated with factors such as education, income, age, place of residence, adherence to medical examinations, perceived stress, and medical coping style. Network analysis revealed that symptoms within the sense of psychological coherence were strongly interconnected, particularly with SOC2 and SOC8, demonstrating the strongest correlations. Among these, SOC10 emerged as the symptom with the highest intensity, centrality, and proximity, identifying it as the most central symptom.

CONCLUSION

The network model has strong explanatory power in describing the psychological consistency symptoms of patients after PCI, identifying the central SOC symptoms, among which SOC10 is the key to overall SOC enhancement, and there is a strong positive correlation between SOC2 and SOC8, emphasizing the need to consider the synergistic effect of symptoms in intervention measures.
Harmonizing the mind and body: The interrelationship between traditional Chinese medicine body constitution, mental health and sleep quality
Authors: Yang Juan-Juan , Wang Qian , Jiang Wei
Published: February 2025

BACKGROUND

Traditional Chinese medicine (TCM) body constitution is a key factor in determining and influencing the occurrence, development, and variation of diseases. As the mind interact with the body, TCM body constitution is useful in preventing and treating psychiatric disorders and insomnia.

AIM

To investigate the interrelationship between TCM body constitution, psychiatric disorders and sleep quality.

METHODS

A total of 2441 participants were enrolled in our study. TCM body constitution was measured using the Constitution in Chinese Medicine Questionnaire, sleep quality was assessed using the Chinese version of the Pittsburgh Sleep Quality Index, and psychopathological symptoms were evaluated using Symptom Checklist-90. Logistic regression was used to estimate the interrelationship between TCM body constitution, psychiatric disorders and sleep quality.

RESULTS

The Pittsburgh Sleep Quality Index score and the proportions of participants with Qi-deficiency constitution, Qi-stagnation constitution, and blood-stasis constitution were significantly higher in the psychiatric symptoms group. Additionally, psychiatric symptoms were considerably associated with sleep quality, Qi-deficiency constitution, and Qi-stagnation constitution, but were inversely associated with male sex. Obsessive–compulsive symptoms were considerably associated with sleep quality, Qi-deficiency constitution and Qi-stagnation constitution. Depression was considerably associated with sleep quality, hyperuricemia, and Qi-stagnation constitution. Anxiety was considerably associated with sleep quality, diabetes, and Qi-stagnation constitution. Finally, poor sleep quality was considerably associated with Qi-deficiency constitution, Qi-stagnation constitution, dampness-heat constitution, phlegm-dampness constitution, and blood-stasis constitution but was inversely associated with male sex and body mass index > 23.9.

CONCLUSION

TCM body constitutions are strongly associated with psychiatric symptoms and sleep quality. Further research is needed to verify whether TCM body constitution can be used to treat and prevent psychiatric conditions as well as enhance sleep quality.

Authors:   M.Tech Scholar, Pragati Engineering College, Surampalem,A.P,India.1, Manohar Gummaregula Siva Sai
Published: February 2025

Power Quality is an essential concern in the modern power system that affects consumers and services. The integration of renewable energy sources, smart grid systems, and the considerable use of power electronics equipment causes a myriad of problems in the current electric power system. It is possible for sensitive equipment to be damaged by harmonics, voltage sags, and swells. These devices are susceptible to input voltage variations created by interference with other parts of the system. Hence, in the modern age, with the development of conscious and expensive electronic equipment, power quality is essential for power system reliable and safe operation. Dynamic Voltage Restorer (DVR) is a potential Distribution Flexible AC Transmission System (D-FACTS) device widely adopted to surmount non-standard voltage, current, or frequency problems in the distribution grid. By injecting voltages into the distribution line, the voltage profile is maintained and a constant voltage is maintained on the load. The simulations were conducted in MATLAB/Simulink to show the DVR-based proposed strategy's effectiveness in smoothing the distorted voltage due to harmonics. In this project, Artificial Neural Network (ANN) controller is used to reduce the total harmonic distortion. It has been noted that the proposed DVR-based strategy effectively managed voltage distortion, and a smooth indemnified load voltage was accomplished.

Index Terms—Dynamic voltage restorer (DVR), artificial neural networks (ANN), power quality, unit vector, voltage harmonics, voltage sag, voltage swells.

The purpose of the research is to improve the fattening and meat qualities of Kalmyk cattle by the method of repro-ductive crossing with the Mandolong breed. Currently, the market's requirements for beef quality, based on the pref-erences of the country's population, have changed significantly. Fatty beef has become less in demand. When chang-ing the requirements for the productive and biological qualities of specialized meat breeds, the attention of breeders is attracted by large, tall breeds of Franco-Italian breeding, which, with intensive raising and fattening technology, are characterized by increased live weight gain at an early age and fat accumulation at a later age. The object of the re-search is animals of the Kalmyk and Mandolong breeds, as well as cross-bred calves of the first generation obtained by reciprocal crossing. As a result of the fact that the live weight of Kalmyk cows is 468 kg, and Mandolong cows – 645 kg, the relative live weight of calves from Kalmyk cows was higher by 1.54%, heifers – by 1.14%, which caused an increase in the number of calving with complications to 35.7 and 12.5% respectively. At the first suckling, calves from Mandolong cows consumed colostrum 6.5-4.5% more than those from Kalmyk cows. In the colostrum of the first milk yield of Kalmyk cows, there was more dry matter by 5.8-6.3%, MJ – by 1.5%, MDB – by 3.9-4.7%. In the colos-trum of Kalmyk cows, IgG is 29.1-29.9% more, IgA is 29.6-28.4%, IgM is 31.5-35.8% more. It was found that immu-noglobulins from the colostrum of Kalmyk cows entered the blood of crossbred calves faster and 6 hours after the first drinking their content was higher, compared to the Mandolong breed, by 8.9-10.2%.

The purpose of the research is to substantiate the implementation of pharmacoprophylactic measures in relation to drug hepatosis in monogastric animals to increase their productivity. In the conditions of the clinic of the Department of Internal Non-infectious Animal Diseases, a simulation of drug hepatosis in white mice was carried out. Three groups of animals were formed (5 individuals each). The mice of the control group received the usual feeding diet, the mice of the experimental groups received the antibacterial drug amoxicillin and a drug with antipyretic, anti-inflammatory and analgesic effects, paracetamol. The drugs were given in maximum therapeutic doses. Additionally, the second experimental group was given the drug «Carnivet» containing carnitine hydrochloride, magnesium sulfate and sorbitol. The experiment lasted 25 days. The clinical condition of laboratory animals and changes in their live weight were evaluated. The diagnosis of hepatosis (or its absence) was confirmed by the results of macro- and mi-croscopic studies of the liver after slaughter of white mice. The clinical condition of the mice of the first experimental group was characterized by depression and intermittent aggression. The average daily gains in live weight were the highest in the mice of the second experimental group and exceeded this indicator in relation to the control group by 28.6%. In the mice of the first experimental group, receiving amoxicillin and paracetamol, by the end of the experi-ment, live weight plumb lines were established. Post-slaughter autopsy of mice of the first experimental group re-vealed typical dystrophic changes in the liver tissue (granular and vacuole dystrophy, karyolysis) and a weakly pro-nounced inflammatory reaction. No such changes were found in the liver of the control group mice. Weakly ex-pressed focal granular and vacuole dystrophy were detected in the liver of animals of the second experimental group. In addition, pronounced «restorative» processes characterized by perivasculitis and single small granulomas as well as an increase in the proportion of binucleated hepatocytes have been established. A conclusion was made about the preventive efficacy of the drug «Carnivet» in relation to toxic hepatosis.

Published: February 2025

This study aimed to inventory the taxonomic diversity of Orchidaceae on the western slopes of Mount Lawu, a conservation area managed by PT Pertamina Aviation Fuel Terminal Adi Sumarmo. Through exploratory methods, 51 orchid taxa were identified with a total of 230 individuals. The Eria, Dendrobium, and Liparis genera dominated the species composition, with their distribution influenced by microhabitat characteristics. The significant presence of epiphytic species suggests a healthy forest canopy. Vegetative propagation efforts through tissue culture were successfully conducted on five selected species: Eria sp, Liparis sp, Dendrobium sp, Malaxidinae sp, and Vanda tricolor, with Dendrobium sp demonstrating the highest potential for vegetative propagation (26%). These findings open avenues for reintroduction programs of rare species into their natural habitats.
A conservation status assessment revealed that most species are not yet listed in the IUCN Red List, emphasizing the urgent need for further research and more intensive conservation efforts. Therefore, this study recommends the implementation of integrated in-situ and ex-situ conservation strategies to ensure the sustainability of orchid diversity within the Mount Lawu conservation area.

Authors: Hassan Kawthar Khalaf , Ali Saja Mahmood , Saleem Raghda Isam
Published: February 2025

Introduction: External ears are distinct and do not alter with age. Ear traits may be as reliable as fingerprints in identifying people. An external ear morphological analysis and observation of Basrah population ear features were undertaken to assess how beneficial the ear is for identification.Aim: This study gathered comprehensive data on the external ear phenotypic variations in the Basrah population.Methods: A cross-sectional study of 608 patients aged 7–70 years (308 men, 300 women). Abnormal ears were omitted. Photographs and population statistics were randomly collected.Results: The predominant ear shape among our population is oval, including 38.7% of males and 42.7% of females. Females predominantly exhibit tongue-type earlobes (44.7%), while males are more likely to possess arched lobes (39.6%). In both genders, the attached earlobe is the second most prevalent ear type, behind the free earlobe (41.2% in males and 60.0% in females). The long variety of the tragus is uncommon, while the knob-shaped variant is more prevalent, seen in 46.8% of males and 51.3% of females. The normal rolled helix is common in both genders. Many individuals in our population lack Darwin’s tubercle.Conclusions: External ear forms vary according to heredity. Despite minor gender and country variations, it is useful in forensics, plastic surgery, and anomaly identification.
Can a set of rules be called a system (rational system)?
Authors: Radzikowski Krzysztof
Published: February 2025

The title of the study is quite surprising. Intuitively, we will answer that, of course, a set of regulations, especiallythose as chaotic and unstable as those currently in force in Poland, is not a system, much less a rational system.However, it is necessary to separate doctrinal ideas and views from the normative reality. The poor quality of lawis not an argument that releases the obligation to observe it. Inevitably, the words system and rationality take on a different meaning in the sphere of normative reality than in the sphere of ideas and doctrinal views. The aim ofthe study is to indicate arguments proving the systemic and rational nature of the set of tax regulations in force in our country, but these are uniquely understood features, distant from the doctrinal requirements of a rational tax system.

Este artículo hace parte de la investigación doctoral que me encuentro adelantando en la Universidad de San Buenaventura (Medellín-Colombia), titulada Experiencias narradas: expresiones de sí en semilleros de creación literaria, en la que propongo acercarme a las narrativas (auto)biográficas que los y las jóvenes producen en tanto que presentan una oportunidad para vislumbrar en estas  las tramas socio-narrativas que las atraviesan, al igual que las posibles articulaciones con la sociedad biográfica de la ciudad de Medellín. En este sentido, la escritura narrativa en estos contextos no es un simple registro de eventos personales, sino una construcción narrativa situada que conecta al individuo con su entorno socio-cultural. Por tanto, resulta oportuno explorar cómo los jóvenes utilizan la escritura para articular sus historias de vida, qué significados emergen de este proceso y cómo estas producciones dialogan con los discursos colectivos que circulan en su contexto.

Выводы: Изучение цитокинового профиля в сравнительном аспекте выявили гиперсекрецию ключевых медиатров Th2 и Th17 иммунного ответа  (IL-4 и IL-17А) и дефицит синтеза ключевого противовирусного цитокине Th1  иммунного ответа (IFN γ) во всех групах детей с пневмонии.
Hvilke rammer gir læreplanverket for skolens antirasistiske arbeid?
Authors: Nyegaard Sara Blikstad
Published: February 2025

In Norway, the public discourse highlights the importance of combating racism through the educational system. However, there is limited knowledge of how these aspirations translate into educational policies and practices. This study examines the framing of antiracism within the Norwegian state curriculum, referred to as LK20. More specifically, it uses reflexive thematic analysis to identify the guidelines for promoting antiracism in the current curriculum. The findings show that while the LK20 curriculum presents various opportunities for working with antiracism, most of the guidelines remain vague and implicit and do not explicitly require a focus on racism or antiracism. Consequently, effectively incorporating antiracism into the LK20 curriculum requires teacher competence and a genuine interest in working with racism and antiracism. The findings of this study highlight issues regarding how the mandate to counteract racism is placed on the interpreters of the curriculum—the individual teacher and local professional communities—and discusses the consequences of the implicit mention of racism in curriculum with regard to policies and practices.

Desafiando las nociones hegemónicas occidentales sobre originalidad y propiedad intelectual, la industria china ha desarrollado una forma de imitación paradójicamente original: el shanzhai. Integrando ideas filosóficas con mi experiencia como arquitecto latinoamericano en Beijing, en este artículo exploro algunas dimensiones culturales, históricas y comerciales sobre el “copiar y pegar” arte y arquitectura en China, desde las copycat cities hasta los parques Disneyland. En última instancia, esta tendencia va más allá de las falsificaciones y el espionaje industrial, pues responde a un arraigado pragmatismo y a valores culturales que seguirán moldeando una economía global donde China ha resurgido como superpotencia.
DE PRÍNCIPE A MENDIGO: LA TRISTE HISTORIA DEL HELICOIDE DE LA ROCA TARPEYA
Authors: Olalquiaga Celeste
Published: February 2025

El boom petrolero de Venezuela a mediados del siglo XX produjo una modernización arquitectónica en el país, sobre todo en Caracas. Uno de los proyectos más sobresalientes por su diseño e historia fue el “Helicoide de la Roca Tarpeya: Centro Cultural y Exposición de Industrias” (1956-1961). Ubicado al centro-sur de la capital, este antecedente de los malls generó gran admiración internacional por esculpir con dinamita el cerro llamado la Roca Tarpeya en forma helicoidal para luego cubrirlo de hormigón armado y realizar la conjunción de comercio y autopista en una estructura rodeada por cuatro kilómetros de rampas vehiculares. Por razones políticas, el Helicoide no pudo ser completado. Varios proyectos estatales, tanto comerciales como culturales, fueron intentados y frenados por la alternancia entre los dos partidos políticos dominantes. Sus dos usos más relevantes han sido “La gran ocupación” (1979-1982), cuando 500 familias de escasos recursos fueron ubicadas allí debido a lluvias torrenciales; y la instalación de las agencias policiales de inteligencia desde 1985 hasta la actualidad. La acción de estas últimas lo ha convertido en cárcel y centro de torturas, sobre todo a partir del ascenso de Nicolás Maduro al poder en 2013, gobierno conocido por la violación sistemática de los derechos humanos. La decadencia del Helicoide representa el fracaso de la modernidad y la democracia en Venezuela.

Practical communication of uncertainty in quantitative landslide risk assessment
Authors: Paul Darren , Miner Tony
Published: February 2025

Uncertainty is inherent in all quantitative landslide risk assessment. However, rarely are the outcomes of a quantitative landslide risk assessment accompanied by an indication of the uncertainty of the assessment. Landslide risk assessment requires the prediction of natural climate, geological and geomorphological processes which cannot be done with complete certainty. Further uncertainty is introduced through error in measurement and observation, variable judgement and bias. This paper sets out practical means by which the uncertainty of landslide risk assessed quantitatively and reported as a probability can be estimated and then communicated to stakeholders or users of the quantitative landslide risk assessment. Methods for estimating epistemic uncertainty arising from error in observation and its interpretation and aleatory uncertainty arising from the unpredictability of natural systems and processes are set out. The uncertainty assessment is based on the estimation of indices using a scoring system. Indices for epistemic uncertainty are linked to the information used to inform the landslide risk assessment and the interpretation of that information. Indices for aleatory uncertainty are linked to the complexity or predictability of the natural system in which the landslide could occur.
Various methods are presented for how the assessed uncertainty can then be communicated to a stakeholder or user of the landslide risk assessment to convey to that user a realistic expectation of the confidence they should have in what is reported to them. These include presenting the uncertainty as an index, describing uncertainty qualitatively, presenting the risk as a range or assuming the risk estimation follows a statistical distribution and presenting confidence limits. Examples of how to estimate and communicate uncertainty are presented for situations involving both the assessment of individual risk and societal risk.
Serviceability and ultimate limit state checks for pile groups via the equivalent pier method
Authors: Poulos Harry
Published: February 2025

The representation of a pile group by an equivalent pier involves significant simplifications, but nevertheless provides a very useful check on the results of more complex analyses of the group. In this paper, previous work on the vertical and lateral responses of an equivalent pier under serviceability limit state (SLS) loadings have been extended to the consideration of the overall stability of the pier under ultimate limit state (ULS) loadings. Approximate expressions for the ultimate axial, lateral and moment resistances of the pier have been adopted, and the stability of the pier has been assessed in terms of a published criterion for foundation failure under combined axial, lateral and moment loads. For this assessment, the computed ultimate resistances have been factored down by a geotechnical reduction factor while various load combinations have been applied to the load components.
For practical application of the equivalent pier approach, some correlations for the estimation of the various geotechnical parameters for both SLS and ULS states has been summarized.
The simplified equivalent pier approaches, for both SLS and ULS loads, have been applied to the foundation system for the Incheon Tower, for which more complex 3-dimensional analyses were undertaken. The simplified approach gives outcomes that are generally consistent with those from the more complex analysis.
Effective stress parameters for Western Sydney clays
Authors: Waddell Peter
Published: February 2025

Western Sydney soils are mainly stiff to hard clays derived from the weathering of fine-grained sedimentary rocks. They occur as alluvial, colluvial and residual deposits which are increasingly being encountered in major infrastructure and building developments as Western Sydney becomes more heavily developed. Mohr-Coulomb effective strength parameters are commonly used for geotechnical assessments and designs such as cut and fill slope stability, retaining walls and piles. These parameters can be obtained from laboratory tests on samples collected from the field as thin-walled tube samples and subject to triaxial testing. In the absence of such testing, it is widespread practice for cohesion and friction angle values to be selected based on ‘typical values’ in the literature and correlations with index tests.

This paper presents analysis of a dataset of laboratory test results from various sites across Western Sydney to assess effective strength parameters for Western Sydney soils with respect to presumptive values in the literature and correlations with index properties.

Elements geochemical anomalies mapping is one of the main goals of geochemical investigations. Since the field studies is time-consuming and costly, the data processing, applying machine learning methods could be applied, which are less expensive, faster, and more accurate. In this study, two machine learning methods, including decision tree algorithm and support vector machine, were applied for gold prospectivity mapping. To reach this aim, silver, copper, lead and zinc values were used as input variables. The comparison of the analytical results obtained from the two mentioned methods confirms that the DT (decision tree) model has sufficient accuracy and better performance than the SVM (support vector machine) model for preparing gold prospectivity mapping in the studied area.

Animal telemetry is maturing into a viable method for observing the ocean as it can be used to monitor both environmental conditions and biological metrics along the movement trajectories of marine animals. As part of the Cormorant Oceanography Project, we have augmented a biologging tag with an external fast response temperature sensor to collect ocean temperature profiles from the backs of foraging marine birds. Cormorants dive between 50 and 250+ times a day to forage for prey so they can provide hard-to-match temporal and spatial coverage of coastal ocean conditions within their foraging areas. We process tag measurements to obtain fundamental oceanographic data (e.g., temperature profiles, bottom soundings, surface current measurements). Together, we have tracked 17 marine bird species (including two Spheniscus penguins spp. and a sea duck), originating from 17 countries and foraging along the edges of all major oceans. Tagged birds’ distribution included 191 MPAs in 26 countries, offering a unique ocean monitoring method to complement more widely used methods.

Graphic design is very important for helping the branding of Micro, Small, and Medium Enterprises (MSMEs), especially in today's competitive digital world. This study aims to look at how creativity and innovation in graphic design affect the success of MSMEs branding. Using a quantitative method, data was gathered through a survey with a Likert-scale-based questionnaire from 25 MSMEs owners in the food, fashion, and craft industries in the Greater Jakarta area (Jabodetabek). The analysis methods used are descriptive analysis and multiple linear regression to assess the link between creativity and innovation in graphic design and branding success. The findings show that graphic design aspects like logos, packaging, and creative promotional visuals can boost product attractiveness (84%), build a solid brand image (86%), and encourage customer loyalty (82%). Participants also mentioned that graphic design plays a key role in increasing the competitiveness of MSMEs in the market (86%). However, limited access to technology and design software (74%) is a significant obstacle that must be tackled. This research shows that graphic design is not just about looks but is also a strategic tool in branding that can strengthen brand identity and help with product marketing. To make better use of graphic design, suggested actions include enhancing access to technology, educating MSMEs owners on branding and graphic design, and working with professional designers. This study gives useful suggestions for MSMEs to implement more creative and innovative branding strategies to boost their competitiveness in a constantly changing market.

Perdagagan bebas yang disepakati dengan negara maju menimbulkan perubahan karakter konsumen di Indonesia [1] ditambah efek pandemi Covid-19 semua komoditi dalam negeri hampir mengalami penuruan penjualan dan laba usaha tiap tahunnya[2]. Perusahaan harus mengubah strategi lain dalam menarik pelanggan menggunakan data karakteristik pelanggan yang berbeda-beda salah satunya data transaksi penjualan [3]. Data tersebut nantinya akan disegmentasi dengan metode clustering. Clustering adalah teknik analisis data yang bertujuan mengelompokkan objek-objek ke dalam grup atau klaster berdasarkan kesamaan karakteristik atau fiturnya. Analisis data dengan clustering diperlukan untuk mengidentifikasi pola dan mengekstrak informasi dari kumpulan data dengan variasi dan jumlah besar, seperti pada identifkasi segmentasi pelanggan. Hasil clustering ini akan memudahkan dalam merumuskan startegi pemasaran berorientasi pelanggan. Penelitian ini menggunakan model Recency, Frequency, and Monetary (RFM) sebagai atribut utama dan teknik clustering k-means, agglomerative, dan DBSCAN. Evaluasi berdasarkan silhouette score, Davis-Bouldin index, dan Calinski-Harabasz index menunjukkan hasil terbaik pada pembentukan tiga cluster dengan algoritma k-means untuk segmentasi pelanggan dalam penelitian ini dengan indeks silhouette score sebesar 0.364, davis-bouldin sebesar 0.93 dan calinski-harabasz sebesar 1303.6 ini menghasilkan 3 klaster pelanggan loyal customer, adequate customer dan churn atau lost customer.
