Authors: Nubatonis Alfred , Allung Blegur Fried Markus , Oki Yeremias , Banu Theodorus
Published: September 2024

Penentuan harga ternak sapi bali yang dilakukan peternak di kelompok tani Bon-Bon selama ini berdasarkan pengamatan visual terhadap fisik sapi dengan kisaran harga jual Rp. 4.000.000 – Rp. 4.500.000. Ketika dilakukan pengukuran morfometrik (Panjang badan 108 Cm dan lingkar dada 150 Cm) memperoleh  data dugaan bobot hidup = 197,2 Kg. Apabila bobot hidup dikalikan dengan standart harga yakni 27.000 per Kg bobot hidup maka harga jual sapi tersebut seharusnya Rp. 5.325.707. Proses penentuan harga berdasarkan pengamatan fisik ini mengakibatkan peternak mengalami kehilangan potensi pendapatan sebesar Rp. 825.707 -Rp.1.325.707. Kondisi ini sangat merugikan peternak di pedesaan, dimana peternak belum mengetahui teknik penetuan harga berdasarkan bobot badan hidup ternak, belum mengetahui teknik pengukuran morfometrik ternak sapi, standart harga jual bobot hidup ternak sapi yang ditetapkan pemerintah Nusa Tenggara Timur. Sosialisi standart harga jual bobot hidup ternak yang ditetapkan pemerintah dan pelatihan teknik pengukuran morfometrik sapi, pembuatan matriks penentuan harga berdasarkan bobot hidup ternak serta pembuatan kandang jepit, diharapkan dapat meningkatkan pengetahuan peternak dalam pendugaan bobot hidup ternak, mengubah proses penentuan harga jual ternak agar meningkatkan pendapatan peternak. Hasil yang dicapai ialah peternak memiliki pengetahuan tentang standar harga jual per Kg bobot hidup dan keterampilan mengukur morfometrik tubuh untuk menghitung bobot badan ternak, tersedianya 15 buah alat ukur morfometrik, 15 unit kandang jepit dan 15 buku matriks harga jual ternak sapi berdasarkan hasil dugaan bobot hidup yang dikalikan dengan standar harga yang ditetap pemerintah. Disimpulkan bahwa dasar penentuan harga jual ternak sapi yang dilakukan peternak berdasarkan hasil dugaan bobot hidup dikalikan dengan harga/Kg/BB.

Authors: Cindrakasih Nabilah Amanah , Hartono Arif
Published: September 2024

This study aims to test and analyze the influence of organizational identification factors, university reputation, tuition fees, and infrastructure on the satisfaction of new students who will later recommend private universities. The research method used is quantitative. This study involved 164 respondents from new students of the 2023 batch of the Islamic University of Indonesia. Data were collected through an online questionnaire using a Google form and analyzed using SPSS and PLS-SEM with SmartPLS software. The results of this study state that organizational identification and tuition fees have a positive and significant effect on student satisfaction. However, the university's reputation and infrastructure do not show a direct positive relationship with student satisfaction. In addition, the results of this study also highlight that student satisfaction has a positive and significant effect on their intention to recommend the university to prospective students. This is very important for university management because it shows that efforts to increase organizational identification and set affordable tuition fees, will later encourage them to recommend the university. This study contributes to the enrichment of higher education marketing literature. This study also recommends marketing managers improve the factors that make students satisfied at the university.

Introduction. Secondary purulent meningitis (SPM) in ENT pathology in adult patients takes a leading position among all intracranial complications (ICC). One of the main components of medical care, along with surgical sanitation of the primary focus is the timely prescription of adequate systemic antimicrobial therapy (SAMT), the choice of which depends on the structure of etiologically significant microorganisms and their sensitivity to antibacterial drugs. Aim of the research. To study the features of the course of SPM in adult patients, the structure of etiologically significant microflora, the sensitivity of the isolated microflora, SAMT tactics in order to optimize the provision of medical care to this category of patients. Materials and methods. Retrospective analysis of medical records of 61 completed cases of SPM over 10 years (2014–2023) with the study of clinical and laboratory parameters, microbial landscape in SPM. Results. It has been demonstrated that in every fourth case, patients are admitted with suspected acute cerebrovascular accident which can lead to a delay in providing comprehensive medical care. Significant symptoms of the inflammatory process were revealed based on the complete blood count and cerebrospinal fluid analysis. The structure of etiological factors in SPM was dominated by coccal microflora (Streptococcus spp., Staphylococcus spp.). The most problematic in terms of sensitivity and selection of effective SAMT were Acinetobacter spp. and representatives of the order Enterobacterales. Polymorphism of microorganisms etiologically significant for the development of SPM, the presence of resistant strains dictated the need to prescribe broad-spectrum antibiotics – meropenem, cefepime in more than half of the cases. Conclusion. Timely diagnosis, clear tactics of providing medical care, including the choice of effective SAMT using, among other things, de-escalation, led to favorable outcomes in 87.9% of patients.

The analytical review examines the problem of postoperative adhesion from the point of view of primary and secondary prevention. Postoperative adhesive formation (adhesion) is the most common complication of surgical treatment which is carried out by general and vascular surgeons, gynecologists and urologists. Postoperative adhesions occur in approximately 90% of all patients undergoing abdominal and pelvic surgery and result in at least one readmission in a third of these patients over the next 10 years. Various pharmacological strategies have been used to reduce adhesion formation, severity and chronicity. During pelvic surgery, strategies to reduce pelvic adhesions include placement of barrier agents, decreased operative time, removal of blood from abdominal cavity during surgery, decreased peritoneal injury, decreased primary inflammatory response, and activation of fibrinolysis. The results of a comparative analysis of the use of various approaches to solving the problem are presented.

Polityka bezpieczeństwa Filipin pod rządami prezydenta Marcosa Juniora (od 2022 roku)
Authors: Czulda Robert
Published: September 2024

Filipiny od kilku lat zmagają się z chińską polityką konfrontacji na Morzu Południowochińskim. Rosnąca presja ze strony Pekinu zmusiła Filipiny do aktywniejszego działania w zakresie polityki zagranicznej i bezpieczeństwa. Poprzedni prezydent Filipin Rodrigo Duterte (2016 ‒ 2022) starał się obniżyć poziom napięcia w relacjach z Chinami i tym samym poprawić strategiczną pozycję Filipin, poprzez odejście od tradycyjnego filaru filipińskiej polityki bezpieczeństwa, jakim jest bliska współpraca ze Stanami Zjednoczonymi. Strategiczne partnerstwo z Waszyngtonem próbował on zastąpił politycznym zbliżeniem z Chinami, ale próba ta zakończyła się niepowodzeniem.
Celem artykułu jest analiza polityki bezpieczeństwa Republiki Filipin pod rządami prezydenta Ferdinanda Marcosa Juniora (od czerwca 2022 roku). Hipotezą jest stwierdzenie, że wybór Ferdinanda Marcosa na prezydenta Filipin był niezbędnym warunkiem, aby doszło do odbudowania strategicznego partnerstwa ze Stanami Zjednoczonymi, które znalazło się w kryzysie w czasie rządów prezydenta Rodrigo Duterte. W artykule zanalizowano geostrategiczne znaczenie Filipin przez pryzmat mocarstw (Stany Zjednoczone i Chiny); genezę odnowienia partnerstwa pomiędzy Manilą a Waszyngtonem; przykłady filipińsko-amerykańskiej współpracy wojskowej; najważniejsze inicjatywy z zakresu modernizacji technicznej Filipin oraz przykłady polityki dywersyfikacji.

Published: September 2024

Celem artykułu jest rekonstrukcja pola problemowego pedagogiki szkoły i podjęcie próby wyprowadzenia jej przedmiotu w procesie konstytuowania się. Ważną podbudową jest ogląd i rozpoznanie genezy tej subdyscypliny, które w Polsce wywodzą się z dorobku pedagogiki szkoły w Niemczech. Artykuł zwraca również uwagę na zjawisko ‘przerwanej drogi’ rozwoju pedagogiki szkoły na gruncie polskim i próbę odtworzenia dorobku subdyscypliny, którą w 2013 roku podjęła prof. Maria Dudzikowa, zaś od 2020 działania te kontynuowane są przez prof. Mirosława J. Szymańskiego i Sekcję Pedagogiki Szkoły przy KNP PAN. Rekonstrukcja naukowego dyskursu służyć ma nie tylko sproblematyzowaniu ram, lecz także umocnieniu tożsamości pedagogiki szkoły w naszym kraju.

O konieczności powrotu do subsydiarnej roli państwa w publicznej edukacji szkolnej
Authors: Śliwerski Bogusław
Published: September 2024

Treścią artykułu jest analiza nowych funkcji szkoły w ponowoczesnym społeczeństwie, które rozwija się w demokracji i dla demokracji. Ta zaś jest możliwa tylko wówczas, kiedy ma miejsce detotatlizacja polityki oświatowej władz centralistycznych, które kierują się w neoliberalnym państwie ideologią etatyzmu jako ukrytej formy demokracji autorytarnej, zamiast wdrażania z udziałem procesów kształcenia i wychowania do demokracji partycypacyjnej i deliberatywnej. Przedstawiam zatem proces koniecznych zmian w polskim systemie szkolnym, które zostały wyrażone w ruchu solidarnościowej opozycji wobec reżimu Polski Ludowej, a na skutek konfliktów społecznych i politycznych w okresie transformacji ustrojowej zostały zaprzepaszczone przez postsolidarnościowe elity władzy. Uzasadniam zatem konieczność powrotu polskich polityków do subsydiarnej roli państwa w publicznej edukacji szkolnej dzieci i młodzieży oraz wskazuję na już istniejące rozwiązania prawne i pedagogiczne w tym zakresie.

Published: September 2024

Neuromyelitis optica spectrum disorder also known as Devic's disease is an autoimmune condition where the body produces antibodies against Aquaporin-4 in the astrocytes. This affects the brain and spinal cord leading to numerous manifestations like paralysis, transverse myelitis, and optic neuritis. MRI and aquaporin-4 antibody (AQP4-IgG) are crucial for its diagnosis. Treatment of the acute stage involves plasma exchange and intravenous steroids. Steroids and immune modulators can do long-term management. This case highlights a 40-year-old woman who manifested a wide range of neurological symptoms, including paralysis and eyesight loss. She had blood testing, radiology, and a clinical evaluation to diagnose her condition. Neuromyelitis optica spectrum disorder was diagnosed in light of the investigations. This instance emphasizes the need for careful examination and consideration of any paralysis. To prevent patients from experiencing psychological, financial, or physical challenges, treating physicians should be vigilant for any findings related to conditions like neuromyelitis optica spectrum disorder.

Finely dispersed СeO2–Nd2O3 and Gd2O3–La2O3–SrO–Ni(Co)2O3–δ mesoporous powders are synthesized by co-crystallization of the corresponding nitrates solutions with ultrasonic treatment and used to prepare nanoceramic materials with a fluorite-like, orthorhombic perovskite and tetragonal perovskite crystal structures respectively with CSR ~ 55–90 нм (1300ºC). The study of physicochemical properties of the obtained ceramic materials revealed an open porosity 7–11% for СeO2–Nd2O3 and 17–42% for Gd2O3–La2O3–SrO–Ni(Co)2O3–ä. Cerium oxide-based materials possess a predominantly ionic electrical conductivity with σ700ºС = 0.31 · 10–2 S/cm (ion transfer number ti = 0.71–0.89 in the temperature range 300–700°C) due to the formation of mobile oxygen vacancies at heterovalent substitution of Nd3+ for Се4+. Solid solutions based on lanthanum nickelate and cobaltite feature a mixed electronic-ionic conductivity with σ700°С = 0.59 ∙ 10–1 S/cm with the electron and ion transfer numbers te = 0.92–0.99 and ti = 0.08–0.01. The obtained ceramic materials are shown to be promising as solid oxide electrolyrtes and electrodes for medium temperature fuel cells.
2d Nanocrystals Of Zinc And Manganese(II, III) Oxides With Morphology Of Perforated Nanoflakes Obtained Using Hydrolysis Reactions Of Mn(OAc)2 AND Zn(OAc)2 By Gaseous Ammonia On The Surface Of Their Aqueous Solutions
Authors: Tolstoy V. P. , Gulina L. B. , Shilovskikh E. E.
Published: September 2024

The paper shows for the first time that 2D ZnO nanocrystals with the structure of wurtzite and Mn3O4 hausmanite and morphology of perforated nanoflakes can be obtained on the basis of compounds that are formed as a result of reactions occurring on the surface of aqueous solutions of acetates of the corresponding metals when it is treated in air atmosphere with gaseous NH3. Application of the marked nanocrystals on the silicon surface makes it hydrophobic in the case of ZnO and superhydrophilic in the case of Mn3O4. Using the proposed synthesis technique, sequential and multiple deposition of these compounds on the substrate surface can be performed and such “multilayers” can exhibit new properties.

Authors: Gavrilova M. A. , Gavrilova D. A. , Evstropiev S. K. , Nikonorov N. V.
Published: September 2024

Porous nanocomposites based on oxide compounds of zinc and manganese are synthesized and their structure, morphology, spectral and photocatalytic properties are studied. It is shown that the resulting porous oxide composites have photocatalytic properties and consist of ZnO, Mn3O4 and ZnMn2O4 nanocrystals with a size of 20–40 nm. The introduction of Mn2+ ions into the crystal lattice of ZnO causes a increase in the size of the unit cell of crystals. The band gap of the composites is 3.26 eV. The kinetics of photocatalytic decomposition in a Chicago Blue Sky dye solution is described by a pseudo-first order equation. In the presence of porous nanocomposites, the processes of oxidation of organic compounds proceed both on the surface of photocatalysts and in solution. The synthesized nanocomposites are promising for use in photocatalytic systems for water purification from organic contaminants.

Authors: Kurniawan Adi , Assa Inriyati
Published: September 2024

This study aimed to assess the effectiveness of health financing for Community Health Efforts (CHE) incentives for health workers in improving the Essential Community Health Efforts program in Jayapura Regency. The research used a qualitative design with a case study approach. The analysis revealed that the health financing for CHE incentives at Puskesmas in Jayapura Regency is insufficient. This is due to the underutilization of budget and local regulations that govern the operation of health centers in the region. The main issue lies in the suboptimal incentives provided to health workers in the Puskesmas CHE program. The study suggests that interventions should be made by maximizing CHE incentives for Puskesmas staff for various reasons. Firstly, Puskesmas employees, especially field staff who work outside the health centers, play a crucial role in the CHE program. Secondly, by maximizing incentives, Puskesmas can effectively address problems related to human resource management, thus improving the performance of health organizations at the local level.

This work comparatively evaluates the tool wear of conventional round tools (CRTs) and self-propelled rotary tools (SPRTs) when turning Inconel 718. Tool wear progression over time was measured and analyzed, simulated for various cutting conditions by creating mathematical and ANN models. This study found a 67% increase in tool life for SPRTs over CRTs, especially at a higher cutting speed of 65 m/min, due to improved heat transmission and steady wear distribution. However, at lower cutting conditions, the tool life gain was 15–18%, indicating that SPRTs could be reliably used at higher cutting conditions to achieve a machining economy. SPRTs exhibited better chip control and reduced built-up edge formation than CRTs. The cutting speed had the largest impact on tool flank wear, with machining time, feed, and depth of cut following closely behind. However, this effect was more prominent for CRTs. The 0.2 mm tool wear criterion was found to be more feasible since tool failure was caused by cutting tool chipping at this threshold instead of progressive growth of flank wear during Inconel 718 turning.

Authors: Holtz Anne , Liebe Jan-David
Published: September 2024

Background: In the context of the telematics infrastructure, new data usage regulations, and the growing potential of artificial intelligence, cloud computing plays a key role in driving the digitalization in the German hospital sector. Methods: Against this background, the study aims to develop and validate a scale for assessing the cloud readiness of German hospitals. It uses the TPOM (Technology, People, Organization, Macro-Environment) framework to create a scoring system. A survey involving 110 Chief Information Officers (CIOs) from German hospitals was conducted, followed by an exploratory factor analysis and reliability testing to refine the items, resulting in a final set of 30 items. Results: The analysis confirmed the statistical robustness and identified key factors contributing to cloud readiness. These include IT security in the dimension “technology”, collaborative research and acceptance for the need to make high quality data available in the dimension “people”, scalability of IT resources in the dimension “organization”, and legal aspects in the dimension “macroenvironment”. The macroenvironment dimension emerged as particularly stable, highlighting the critical role of regulatory compliance in the healthcare sector. Conclusion: The findings suggest a certain degree of cloud readiness among German hospitals, with potential for improvement in all four dimensions. Systemically, legal requirements and a challenging political environment are top concerns for CIOs, impacting their cloud readiness.

Introduction: Process Mining (PM) has emerged as a transformative tool in healthcare, facilitating the enhancement of process models and predicting potential anomalies. However, the widespread application of PM in healthcare is hindered by the lack of structured event logs and specific data privacy regulations. Concept: This paper introduces a pipeline that converts routine healthcare data into PM-compatible event logs, leveraging the newly available permissions under the Health Data Utilization Act to use healthcare data. Implementation: Our system exploits the Core Data Sets (CDS) provided by Data Integration Centers (DICs). It involves converting routine data into Fast Healthcare Interoperable Resources (FHIR), storing it locally, and subsequently transforming it into standardized PM event logs through FHIR queries applicable on any DIC. This facilitates the extraction of detailed, actionable insights across various healthcare settings without altering existing DIC infrastructures. Lessons Learned: Challenges encountered include handling the variability and quality of data, and overcoming network and computational constraints. Our pipeline demonstrates how PM can be applied even in complex systems like healthcare, by allowing for a standardized yet flexible analysis pipeline which is widely applicable.The successful application emphasize the critical role of tailored event log generation and data querying capabilities in enabling effective PM applications, thus enabling evidence-based improvements in healthcare processes.

Introduction: NFDI4Health is a consortium funded by the German Research Foundation to make structured health data findable and accessible internationally according to the FAIR principles. Its goal is bringing data users and Data Holding Organizations (DHOs) together. It mainly considers DHOs conducting epidemiological and public health studies or clinical trials. Methods: Local data hubs (LDH) are provided for such DHOs to connect decentralized local research data management within their organizations with the option of publishing shareable metadata via centralized NFDI4Health services such as the German central Health Study Hub. The LDH platform is based on FAIRDOM SEEK and provides a complete and flexible, locally controlled data and information management platform for health research data. A tailored NFDI4Health metadata schema for studies and their corresponding resources has been developed which is fully supported by the LDH software, e.g. for metadata transfer to other NFDI4Health services. Results: The SEEK platform has been technically enhanced to support extended metadata structures tailored to the needs of the user communities in addition to the existing metadata structuring of SEEK. Conclusion: With the LDH and the MDS, the NFDI4Health provides all DHOs with a standardized and free and open source research data management platform for the FAIR exchange of structured health data.

Pancreatic cancer, renowned for its aggressive nature and poor prognosis, necessitates the optimization of treatment strategies. The sequence of procedures in clinical trials is critical, such as evaluating the potential benefits of preoperative chemo-radio-therapy for pancreatic cancer. Nevertheless, we might not be aware of other temporal sequences which have an effect on therapy response or the general outcome. Extracting transitive sequential patterns from patients’ medical trajectories allows researchers to identify temporal characteristics for complex diseases. We illustrate how such sequential patterns can be discovered and might be utilized in pancreatic cancer research as well as patient care.

Published: September 2024

Introduction: Secure Multi-Party Computation (SMPC) offers a powerful tool for collaborative healthcare research while preserving patient data privacy. State of the art: However, existing SMPC frameworks often require separate executions for each desired computation and measurement period, limiting user flexibility. Concept. This research explores the potential of a client-driven metaprotocol for the Federated Secure Computing (FSC) framework and its SImple Multiparty ComputatiON (SIMON) protocol as a step towards more flexible SMPC solutions. Implementation: This client-driven metaprotocol empowers users to specify and execute multiple calculations across diverse measurement periods within a single client-side code execution. This eliminates the need for repeated code executions and streamlines the analysis process. The metaprotocol offers a user-friendly interface, enabling researchers with limited cryptography expertise to leverage the power of SMPC for complex healthcare analyses. Lessons learned: We evaluate the performance of the client-driven metaprotocol against a baseline iterative approach. Our evaluation demonstrates performance improvements compared to traditional iterative approaches, making this metaprotocol a valuable tool for advancing secure and efficient collaborative healthcare research.

Introduction: A modern approach to ensuring privacy when sharing datasets is the use of synthetic data generation methods, which often claim to outperform classic anonymization techniques in the trade-off between data utility and privacy. Recently, it was demonstrated that various deep learning-based approaches are able to generate useful synthesized datasets, often based on domain-specific analyses. However, evaluating the privacy implications of releasing synthetic data remains a challenging problem, especially when the goal is to conform with data protection guidelines. Methods: Therefore, the recent privacy risk quantification framework Anonymeter has been built for evaluating multiple possible vulnerabilities, which are specifically based on privacy risks that are considered by the European Data Protection Board, i.e. singling out, linkability, and attribute inference. This framework was applied to a synthetic data generation study from the epidemiological domain, where the synthesization replicates time and age trends previously found in data collected during the DONALD cohort study (1312 participants, 16 time points). The conducted privacy analyses are presented, which place a focus on the vulnerability of outliers. Results: The resulting privacy scores are discussed, which vary greatly between the different types of attacks. Conclusion: Challenges encountered during their implementation and during the interpretation of their results are highlighted, and it is concluded that privacy risk assessment for synthetic data remains an open problem.
