Pemberdayaan Kesejahteraan Keluarga (PKK) di Nagari Sunua Tengah menjadi sangat penting untuk meningkatkan kapasitas ibu rumah tangga guna menciptakan kemandirian ekonomi. Nagari Sunua Tengah memiliki banyak potensi untuk dikembangkan, terlebih adat istiadat Pariaman yang masih sangat kental melekat pada masyarakat Nagari Sunua Tengah. Salah satu tradisi adat yang paling terkenal pada adat Pariaman yakni tradisi Bajapuik pada upacara pernikahan. Hal menarik yang ditemukan pada tradisi Bajapuik di upacara pernikahan anak laki laki dalam adat pariaman ini adalah adanya Juadah. Juadah merupakan hantaran khas dalam setiap acara perkawinan. Biasanya, hantaran ini disusun dalam talam-talam yang besar. Hantaran ini akan jadi makanan pelengkap di pesta pertunangan (batuka tando) dan perkawinan di rumah mempelai pria. Juadah ini menggunakan talam yang bertingkat-tingkat, dimana yang paling atas diisi beberapa kue bolu, lalu berturut-turut di talam bawahnya ada beberapa pangan khas sebagai pelengkap isian Juadah. Isian pelengkap Juadah bisanya disesuaikan dengan permintaan keluarga mempelai laki laki. Seiring perkembangan zaman, proses dalam pembuatan Juadah ini hampir tidak lagi ditemukan di rumah pengantin Wanita. Sebagian besar masyarakat Nagari Sunua Tengah lebih memilih untuk membeli kue bolu yang digunakan sebagai isian Juadah dari pada harus membuat sendiri. Hal ini dikarenakan alasan kepraktisan dan kemudahan. Potensi bisnis inilah yang sebenarnya dapat dimanfaatkan oleh tim PKK Nagari Sunua Tengah dalam upaya menciptakan kemandirian ekonomi

The idea of lifelong learning has long been highlighted by researchers and experts as an important context for adult education, and its significance is also emphasized by organizations such as UNESCO, OECD, and the EU. Similarly, in national documents like the Integrated Skills Strategy, the importance of lifelong learning and the acquisition of basic skills, which are crucial for individual development and preventing social inequalities, is stressed.

The aim of the article is to present a new approach to understanding and teaching basic skills in adult education, based on a relational model developed from research on new media. The analysis drew on findings from in-depth interviews conducted with coordinators and participants of the project “A Chance – New Opportunities for Adults.” The research aimed to both assess the methods of testing models developed within the project and analyze the individual educational activities of the participants, their practices, and strategies for dealing with competency gaps in their private and professional lives, as well as to identify the key factors contributing to the low level of basic skills. In the article’s conclusion, the authors emphasize that basic skills should be understood dynamically and flexibly, in the context of individuals, daily activities and needs. Their teaching cannot rely solely on rigid catalogs of skills, but should take into account both the personal and social goals of the participants. The relational approach to education, which emphasizes functionality and individual resources, offers a broader perspective for adapting educational content to the real needs of adults.
Włączanie cyfrowe osób z niepełnosprawnością intelektualną jako praktyczna egzemplifikacja lifelong learning na rzecz przeciwdziałania wykluczeniu społecznemu
Authors: Kowalski Kacper

There is no denying that in the 21st century, part of our lives is reflected or extended in the digital world. Unfortunately, not everyone is still able to use information and communication technology (ICT) or to do so in an appropriate and safe manner. The group of digitally excluded people includes those with intellectual disabilities. This article illustrates the dimensions of digital exclusion of people with intellectual disabilities and its consequences, and above all, emphasises the essence of digital inclusion.

The text aims to present the theoretical basis and principles of digital inclusion as a practical example of lifelong learning, which is a way of counteracting social exclusion – in the described case of people with intellectual disabilities. Digital inclusion is directly related to social inclusion, and people with disabilities belong to a group at risk of both digital and social exclusion. This is confirmed by the statistics cited in the text and an overview of international research on the ‘being and non-being’ of this social group in digital space, which is the starting point for demonstrating the need and multidimensionality of activities for digital inclusion. Media education and its guidelines for working with people with intellectual disabilities, presented in the text, are intended to show the connections with the basics of lifelong learning, so as to see their reciprocity with the foundations of theory and research, and above all in practice. The text is part of the work on a doctoral dissertation, which is based on autoethnographic research by the author – a digital educator for people with disabilities – on the social aspect of digital inclusion for people with intellectual disabilities. However, the article is the result of theoretical considerations, hence its review-like character.

Self-reported Provision of Preconception Care and Associated Factors
Authors: Morema Everlyne N , Ouma Collins , Egessa Robert , Nyachiro Lydia , Shisanya Morris
Published: February 2025

ABSTRACT
Background: Preconception care (PCC) is the provision of health interventions to women and couples before conception occurs and is valuable in promoting healthy maternal, birth, and neonatal health outcomes. In Africa, more so in Kenya, maternal and neonatal health indicators have remained poor. The key constraint limiting progress is the gap between what is needed and what exists in terms of skills and availability of human resources & infrastructures in the face of increased demand. This gap was yet to be measured for PCC in Kenya, more so in Kisumu County.
Methods: Using a cross-sectional design, this study specifically sought to determine the rate of self-reported PCC provision and to illustrate how it is influenced by health provider characteristics. Structured interviews were conducted with health providers (n=476) to ascertain their knowledge, perceptions and practice of PCC care. The significance of the differences in means was determined by the Student’s t test and linear regression were used to show the relationship between the health provider characteristics and the PCC provision rate.
Results: Self-reported PCC provision was estimated at 39%. There was a significant difference in the mean for cadres {nurses (M=70.04, SD=8.951) and non-nurses (M=71.90, SD=8.732); t (473) =-2.23, P=.026)}, years of experience up to 5 years (M=72.04, SD=8.417) and more than 5 years (M=69.89, SD=9.283); t (465) =2.63, P=.009, the mean provision per level (M=60.21, SD=4.902; t (26)=-5.06, P<.001) and type of service (M=69.36, SD=4.924; t (26) =4.63, P<.001). A significant regression model was found, and the model statistics were F (2,464) =5.97, P=.003, R2=.03. Only cadre (b=0.01, t (464) =2.23, P=.026) and years of experience (b=-0.13, t (464) =-2.79, P=.005) were significant determinants of PCC provision. The health workers felt PCC was an important service whose provision was low due to inadequate human capital investment.
Conclusion: Self-reported provision of PCC by health workers was relatively low and was influenced by the cadre of health workers and their years of experience. It specifically demonstrated the importance of various aspects of human capital, i.e., knowledge, perceptions, competence and adequacy of training in the provision of this care. Furthermore, it showed that the nursing cadre has a higher probability of providing this care. Investing in on-the-job training for health providers, especially nurses, and providing care in primary health facilities in rural areas can improve PCC service delivery.

Demographic lag in Saudi Arabia explained
Authors: Salam Asharaf Abdul , Alhamoudi Abdullah Mazen
Published: February 2025

The demography of Saudi Arabia has been discussed many times but its conflict with the theories of transition and associated structural changes is unexplained. This research explains the demographic differentials stated as lag - real from theoretical – separately for the native and total population. This research developed demographic indicators revealing trends and patterns by adopting a secondary data analysis method, utilizing the General Authority for Statistics census data and other online data. The demographic transition of Saudi Arabia is in line with the theoretical contentions of pretransition and transition (early, mid, and late) stages but at definite time intervals. The absolute size, percentage change, and annual growth rate are explanatory for natives and are considered separately. Moreover, the structural population changes reveal transition stages from expansive to near expansive and constricting and stabilizing. Furthermore, broad age groups indicate rapid declines in the percentage of children, rapid increases in young adults, slow increases in older adults, and no changes in older persons. Even the sex ratio of natives is at par with other populations in transition (slightly above 100). Thus, it could be concluded that a demographic transition with structural changes as per theories: flawless growth rates with an expanding demographic dividend. At this juncture, the integration of migrants into society by endorsing family life and enabling social and demographic balance appears as imperative to improving the labor sector, productivity, and the image of the country in the international spheres for comparisons and benchmarking.
Temporal changes in diversity of vascular flora accompanying Salix viminalis L. plantations
Authors: Janicka Maria , Kutkowska Aneta , Paderewski Jakub
Published: February 2025

In recent years, there has been increasing interest in the floristic diversity of agroecosystems, particularly for plant conservation. While old plantations claim to be more floristically diverse, little is known about this for Salix viminalis L. plantations. The aim of study was to analyse the vegetation accompanying S. viminalis and its dynamics as plantations age. The vegetation was identified in 20 plantations, based on 244 phytosociological relevés. For each species, the following were defined: botanical family, geographical and historical groups, origin of apophytes, biological stability, life-form, botanical class and phytosociological class. The relative coverage of major plant groups was statistically processed using the analysis of variance with a linear mixed model. The flora of S. viminalis plantations is rich and diverse; in central Poland, it consisted of 193 plant species. These species belonged to many phytosociological classes, of which two dominated: Molinio-Arrhenatheretea (46 species) and Artemisietea vulgaris (32 species). Perennial species, meadow, woodland, and shrub apophytes, as well as hemicryptophytes, were prevalent. As the plantations aged, the proportion of perennial species, meadow, woodland, and shrub apophytes increased, while therophytes and anthropophytes declined. Photophilous species dominated mainly in young crops (4–5 years old), but their coverage and frequency decreased over time. With plantations age, vascular flora diversity (total number of species) and coverage of ecologically important groups (Poaceae family, Molinio-Arrhenatheretea class) decreased. These were gradually replaced by mega- and nanophanerophytes and species from the A. vulgaris class. The stabilisation of flora occurred after eight years of willow cultivation.

Background

Sarcopenia, defined by a loss of skeletal muscle mass and function, has been identified as a prevalent condition associated with poor clinical outcome among critically ill patients. This study aims to evaluate the impact of pre-existing sarcopenia on outcomes in critically ill patients with acute respiratory failure (ARF) due to COVID-19.

Material and Methods

A retrospective study was carried out on COVID-19 patients admitted to intensive care. Pre-existing sarcopenia was assessed using early CT scans. Clinical outcomes, including duration of high-flow oxygenation (HFO), mechanical ventilation (MV), length of hospital stay (LOS) and ICU mortality, were evaluated according to sarcopenia status.

Results

Among the studied population, we found a high prevalence (75 patients, 50%) of pre-existing sarcopenia, predominantly in older male patients. Pre-existing sarcopenia significantly impacted HFO duration (6.8 (+/−4.4) vs. 5 (+/−2.9) days; p=0.005) but did not significantly affect MV requirement (21 (28%) vs. 23 (37.3%); p=185), MV duration (7 vs. 10 days; p=0.233), ICU mortality (12 (16%) vs. 10 (13.3 %); p=0.644) or hospital LOS (27 vs. 25 days; p=0.509). No differences in outcomes were observed between sarcopenic and non-sarcopenic obese patients.

Conclusions

Pre-existing sarcopenia in critically ill COVID-19 patients is associated with longer HFO duration but not with other adverse outcomes. Further research is needed to elucidate the mechanisms and broader impact of sarcopenia on septic critically ill patient outcomes.

La investigación analiza la calidad del agua subterránea y la eficacia del funcionamiento de dos plantas de tratamiento de efluentes domiciliarios en dos centros urbanos de Paraguay, así como la presencia de metales pesados en lodos residuales de ambas plantas de tratamiento. Para analizar la calidad del agua subterránea se recabaron datos de 59 muestreos de agua de 17 pozos profundos obtenidos en un periodo de 10 años entre 2006 y 2016. Para la evaluación del funcionamiento de las plantas de tratamiento se determinó la calidad de los efluentes luego del proceso de depuración. En los lodos generados en ambas plantas se analizó la presencia de metales pesados (Pb, Cr total, Cd y Hg). Los resultados obtenidos se contrastaron con legislaciones nacionales e internacionales vigentes. Los datos cuantitativos se procesaron estadísticamente mediante análisis de varianza y contraste de medias (test de Duncan) con margen de error de 5 %. Los principales resultados indican contaminación microbiológica del agua subterránea (acuífero Guaraní). Sin embargo, los parámetros físico-químicos analizados estaban dentro de los rangos establecidos por las normativas vigentes. Se identificó una inadecuada gestión en la planta de tratamiento de aguas residuales en uno de los centros urbanos (Hohenau). Se detectó presencia de Pb, Cr y Hg, a pesar de que las concentraciones se mantuvieron dentro de los rangos permisibles. Para salvaguardar la salud pública y el ambiente tanto a nivel local como regional es imperativo aplicar plenamente el marco legal y la implementación de la gestión integrada de los recursos hídricos.

Published: February 2025

Portal vein thrombosis (PVT) is a rare but serious condition that can lead to significant complications such as portal hypertension and gastrointestinal ischemia. This report discusses a unique case of extensive PVT involving the mesenteric veins, splenic infarction, gastroesophageal varices, and colorectal neoplasms with high-grade dysplasia. A 55-year-old woman with no notable medical history presented with recurrent abdominal pain after meals, poor appetite, and occasional vomiting. Imaging studies showed thrombosis in the portal vein, splenic vein, superior mesenteric vein (SMV), and inferior mesenteric vein (IMV), along with signs of splenic infarction. Endoscopic examinations revealed grade I esophageal varices, type 2 gastroesophageal varices, and several polyps in the colon and rectum. Histopathological analysis confirmed the presence of tubulovillous adenomas with high-grade dysplasia in the rectum, raising concerns about potential malignancy. Laboratory tests indicated microcytic hypochromic anemia and an elevated INR, which required anticoagulation treatment with warfarin. This case illustrates the complexities involved in diagnosing and managing PVT and its complications, especially when colorectal neoplasia is also present. A multidisciplinary approach is essential to tackle the various challenges posed by this condition and to improve patient outcomes. Further research into the connections between thrombosis, malignancy, and hypercoagulability is crucial for enhancing understanding and treatment options.

Stem cell therapy has emerged as a transformative approach in dental tissue regeneration, offering innovative solutions for treating various oral and maxillofacial conditions. Stem cells possess the unique ability to differentiate into various cell types, making them an ideal candidate for regenerating dental tissues, including pulp, periodontal ligaments, and even alveolar bone. Researchers are exploring the use of stem cells derived from multiple sources, such as dental pulp, periodontal tissues, and even induced pluripotent stem cells, to support the regeneration of damaged or diseased structures. These advancements hold the potential to revolutionize traditional dental treatments, allowing for more effective repair of dental tissues and reducing the need for invasive procedures like tooth extraction or grafting. The application of stem cell therapy in dentistry is not limited to pulp regeneration but extends to periodontitis treatment and the restoration of oral function. Recent studies indicate that stem cells can promote healing and reattachment of periodontal tissues, thereby addressing the challenge of tooth loss due to gum disease. Furthermore, the integration of stem cells with biomaterials and scaffolding techniques can optimize the regenerative process, ensuring adequate support and growth of the newly formed tissues. These developments not only enhance the efficacy of dental treatments but also pave the way for personalized regenerative medicine in dentistry, tailoring therapies to individual patient needs and paving the path towards a future where dental tissue regeneration could become a standard practice.
A case of neonatal gastric teratoma complicated with occult gastrointestinal hemorrhage misdiagnosed as lymphangioma
Authors: Li Bin De , Wei Kexiang
Published: February 2025

Background. Gastric teratoma is a rare neoplasm, particularly in neonates, and usually presents as a palpable abdominal mass. However, severe occult gastrointestinal bleeding is uncommon and often misdiagnosed. Imaging studies are crucial for the preoperative diagnosis of neonatal teratoma, but definitive diagnosis relies on pathological examination.
Case Presentation. A 28-day-old boy presented with abdominal distension accompanied by vomiting for 2 days without hematemesis or melena. A complete blood count upon admission showed a hemoglobin level of 37 g/L. Ultrasound and computed tomography scans indicated a large cystic, solid mass in the abdominal cavity (approximately 9.8 × 8.8 × 11.2 cm), containing nodules, septa, calcification, and fat, and causing gastrointestinal compression. The mass was misdiagnosed as lymphangioma with hemorrhage before surgery. During surgery, the upper pole of the tumor was found to be fused with the gastric wall of the greater curvature of the fundus of the stomach, with most of the tumor growing exophytically and a small portion growing into the gastric lumen. The tumor, along with part of the gastric wall at the attachment site, was completely removed. Postoperative pathological examination revealed an immature teratoma grade 1. After discharge, the patient’s growth and development were normal, with no adverse manifestations.
Conclusions. Neonatal gastric teratoma with severe occult gastrointestinal bleeding is extremely rare and hence must be on the list of differential diagnoses of neonatal abdominal mass when a cystic solid mass is found, especially when accompanied by severe anemia without obvious gastrointestinal bleeding. Attention should be paid to the location of the lesion, which is predominantly in the left upper abdomen and has been significantly pushed and displaced by the gastrointestinal tract, and to the imaging characteristics of teratoma such as fat and calcification, which help to exclude other palpable masses encountered during the neonatal period.

Published: February 2025

Background. The prevalence of acute suppurative appendicitis (ASA) is the highest among pediatric cases of acute abdominal conditions. This research examined the stress response linked to surgical techniques and identified potential biomarkers that could predict postoperative complications to enhance clinical treatment strategies.
Methods. This study involved a selection of 166 ASA patients who underwent laparoscopic appendectomy (LA), and 150 patients who underwent open appendectomy (OA), based on data collected from 2020 to 2023. Comprehensive documentation of clinical and pathological characteristics, as well as postoperative complications, was conducted following patient enrollment. Quantitative polymerase chain reaction (qPCR), enzyme-linked immunosorbent assay (ELISA), and blood smear techniques were employed to assess the levels of microRNA (miR)-155-5p, C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD), and malondialdehyde (MDA), as well as changes in leukocytes, neutrophils, and lymphocytes at preoperative and postoperative 0 h, and 24 h. A logistic regression model was utilized to identify risk factors associated with the development of complications. Furthermore, receiver operating characteristic (ROC) curve analysis was performed to assess the predictive capacity of miR-155-5p for the occurrence of complications.
Results. The study revealed that the levels of miR-155-5p postoperatively in patients undergoing OA was significantly greater than that observed in patients undergoing LA (P

Seven-Zone Parametric Optimization Method for Compressor Profile with Controllable Maximum Thickness
Authors: Qi Mengyao , Li Xuesong , Ren Xiaodong , Gu Chunwei , Li Yuhong
Published: February 2025

Currently, many parametric optimization methods for designing compressor blades with a controllable maximum thickness directly use the intersection points of segmented curves on the suction side as the maximum thickness points. This approach reduces the parametric freedom and results in a distorted blade when the maximum thickness position changes. There is an urgent need for parametric optimization methods with higher degrees of freedom and greater optimization potential. In this paper, a seven-zone parametric design optimization method based on a controllable maximum thickness is proposed. The seven-zone modeling method is combined with the maximum thickness constraint method with high degrees of freedom, which has better local adjustability while ensuring the profile strength requirements. By combining the flow surface calculation method, computational fluid dynamics (CFD) analysis, and experimental measurement technique, it was found that the optimized blades exhibited a significant reduction in the total pressure loss and a notable expansion of the low-loss operating range. The flow state of the suction surface has the most significant effect on the loss reduction. The change of pressure gradient on the suction surface makes the transition or separation position move backward, and the separation and friction loss decrease, which is conducive to reducing the overall loss.

The aim of this study is to determine the moderating role of climacteric period in the influence of positive psychological capital on affective commitment. The universe of the research consists of female employees in private hospitals in Mersin province. 412 questionnaires were collected and analyzed through convenience sampling from the research universe. The “Positive Psychological Capital Scale”, developed by Luthans et al. (2007), and specific items of “Organizational Commitment Scale”, developed by Meyer et al. (1993), each of which involve in measuring affective organizational commitment, were used for data collection. Confirmatory factor analysis, descriptive statistics and hierarchical regression analysis were used in data analysis. The results of the study show that while positive psychological capital and its sub-dimensions influence affective commitment, the climacteric period has no moderating role in the influence of positive psychological capital on affective commitment. As a result, the findings of the study highlights that it is important to make use of positive psychological capital to ensure affective commitment, which in turn aids in individual and organizational goals.
On the meaning of the term symbol in the writings of Plutarch of Chaeronea
Authors:   Saint Petersburg State University, Kurdybaylo Dmitry
Published: February 2025

Plutarch of Chaeronea was a prominent Middle Platonist, influential both in early Christian Platonism and in pagan Neoplatonic schools. One of the significant markers of this succession is an increasing interest in symbolism and terminological usage of the term symbol. As Plutarch provided almost no explicit theory of symbolism, this research focuses on the contextual word usage in his writings, its analysis and reconstruction of Plutarchian symbolism in the philosophical milieu of his time. Plutarch understands symbol as a two-level entity, which combines an ordinary object or object-related action with a signification of some other entity that is absent, invisible or otherwise imperceptible, so a symbol points to it or acts instead of it. Unlike signs, symbols are ambiguous and may have multiple meanings. Moreover, the polysemanticism of a symbol is considered its strong advantage that reveals the ontological profundity of the symbolized entity. Symbols may appear odd and amazing, thus provoking philosophical inspiration in a person trying to decipher them. Along with single symbols, Plutarch provides examples of integral symbolic systems, among which he mentions human languages. Finally, symbols may be not only passive pointers or reminders but also actors, which influence human decisions and deeds. Plutarch provides a detailed description of the way daemons use symbols as a means to induce mortals to make correct choices. The general pattern of Plutarchian symbolism can be compared with similar conceptions of Clement of Alexandria, Porphyry of Tyre, and Iamblichus of Chalcis.
