Published: December 2024

Salah satu langkah penting dalam pengenalan objek adalah segmentasi gambar, proses memisahkan objek yang relevan dari latar belakangnya, Segmentasi gambar yang efektif  meningkatkan akurasi dan efisiensi seluruh sistem deteksi objek. Pada dasarnya, ruang warna RGB yang umum digunakan tidak selalu optimal untuk analisis visual, terutama dalam lingkungan yang bervariasi pencahayaannya atau warna yang harus diidentifikasi secara spesifik. Oleh karena itu Dalam penelitian ini, membandingkan kinerja segmentasi ruang warna HSV dan YCbCr untuk deteksi objek. HSV (Hue, Saturation, Value) terdiri dari Hue mewakili warna dasar, Saturation mengukur kejelasan warna (intensitas atau kejenuhan), Value menunjukkan kecerahan warna. YCbCr (Luma, Blue-difference, Red-difference), Y adalah komponen luma yang merepresentasikan tingkat kecerahan, Cb dan Cr adalah komponen chrominance yang merepresentasikan informasi warna (biru dan merah), yang dapat mengisolasi aspek warna, intensitas, dan kecerahan.. Tujuan penelitian ini memberikan kontribusi penting untuk memahami keunggulan YCbCr dibandingkan HSV dalam konteks deteksi objek, serta memberikan pedoman praktis untuk penerapan teknik deteksi objek secara lebih efektif dan efisien. Hasil analisis dan eksperimen yang dilakukan, nilai PSNR (Peak Signal-to-Noise Ratio) paling besar pada citra 1  hasil segmentasi menggunakan ruang warna YCbCr dengan nilai 14,0627 dB dan nilai HSV paling besar bernilai 10,2397 dB.  Berdasarkan nilai PSNR ruang warnaYCbCr memberikan kinerja  unggul dalam hal  segmentasi, , dan efisiensi komputasi.

Reassessing International Art Exhibitions in Finland
Authors: Koskinen Maija
Published: December 2024

Cold War politics accelerated artistic exchange and the transnational circulation of art. Within state-run cultural diplomacy, hundreds of art exhibitions traveled to Finland opening a rich and varied perspective on international art. Only a few of them have though made their way into the canon of exhibitions and consequently, into the Finnish history of art. Using a few Cold War art exhibitions as an example, the article challenges the established Finnish art historical canon of significant exhibitions. It demonstrates that many interesting exhibitions have been ignored or marginalized without a good reason due to prejudices or because they have been considered awkward, for instance, for political reasons. The formation of the art canon and exhibition histories are interrelated. Thus, the article suggests that Finnish art history of the second half of the 1900s would look different if more attention had been paid to a greater variety of art exhibitions. It argues that a more profound and detailed knowledge of exhibition histories would provide new perspectives into the transnational circulation of artistic influences and the impact of international art on Finnish art, artists, and the art scene.
Conservative Traditions in Polish Art History
Authors: Łabowicz-Dymanus Karolina
Published: December 2024

This article investigates the persistence of adherence to traditional approaches in Polish art history and the challenges faced in attempting to challenge it. The analysis reveals how art historians in Poland have adhered to notions of ‘objective’ and apolitical science, perpetuating earlier methodologies based on a factographic-object approach. This prevailing mindset inhibits the acceptance of newer, critical frameworks. The paper explores significant historical figures, institutional structures, and movements that have contributed to these conservative trends, while advocating for a more self-reflective approach in line with global methodological developments. By confronting resistance to change, the discipline can broaden its academic and cultural relevance.
Overcoming Mutual Estrangement?
Authors: Renard Margot
Published: December 2024

Despite their relevance in art history, comics have been largely overlooked in the research field. This article builds on recent scholarship that has addressed their historical marginalization in the field by focusing on Jean Dytar’s graphic novel #J’Accuse…! (2021). The graphic novel revisits the Dreyfus Affair, a pivotal event in nineteenth-century France that marked the rise of mass media by generating an unprecedented media coverage. Drawing from art history and media archaeology, the article explores how Dytar’s narrative intertwines past and present to propose a graphic theory of media and examine the notion of “historical event.”

Purpose: Musique concrete creation ‘The Genesis Chapter One’ explores the theme of the creation of the universe based on the Bible in Genesis 1:1-31. This composition encompasses natural soundscapes as sound sources and presenting the work in spatial audio. This project aims to articulate the aesthetics of musique concrete as a reference for future creations and to explore how communication is established with the audience through spatial audio techniques. Unlike conventional musique concrete, this work assigns meaning to each medium used and presents it in a spatial audio format. Methods:The creation process is guided by theories of musique concrete and Roland Barthes' semiotics, using a method developed from Alma M. Hawkins' approach, which includes three stages: pre-production (exploration and improvisation), production (forming), and post-production (recording). Results and Discussion: The mediums used include soundscape sampling, synthesizers, human vocals, and drums, with live presentation utilizing spatial surround 6.1. Conclusion: The work is divided into three parts: Part I depicts the state before creation, Part II focuses on the growth of the universe with rhythm, and Part III is inspired by the human heartbeat, symbolizing life and its correlation with the universe.

Published: December 2024

Multiple sclerosis (MS) is a chronic disorder of the central nervous system affecting primarily young women. Neurogenic lower urinary tract dysfunction (NLUTD) represents one of the disease manifestations creating the risk of infectious complications and kidney disease. Today, there is insufficient data on the urinary microflora composition obtained by advanced high-tech diagnosis methods. The study aimed to perform clinical assessment of NLUTD associated with MS and its impact on the quality of life (QOL), as well as to clarify the data on the urinary microflora composition. A total of 33 women with MS aged 36 [39.5; 30.5] years were assessed using the customized questionnaires for estimation of the NLUTD prevalence and severity, as well as for QOL evaluation. Qualitative determination and quantification of urinary opportunistic microflora (OM) were performed using the real-time polymerase chain reaction. A total of 19 (57.6%) women with MS had symptoms of NLUTD: symptoms of the storage (15 individuals, 45.5%) and emptying (16 individuals, 48.5%) phases. In almost half of women with MS, the complaints included abnormalities of both bladder functioning phases (12 individuals, 36.4%); moderate abnormalities prevailed (12 individuals, 34.6%). Women with MS and NLUTD were more disabled based on the EDSS score (3.5 [5.0; 3.0] points; p < 0.001) and had longer disease duration (13 [20.0; 5.0] years; p < 0.001). The QOL index of women with NLUTD showed dissatisfaction with bladder function. The study revealed bacteriuria in patients with MS and NLUTD. The data on the urinary microflora composition are provided: OM members (bacteria of the ESKAPE group) have been found in 8 samples obtained from women with MS and NLUTD. Bacteriuria was asymptomatic.

Creating a classroom tiriti with young learners: A pathway to understanding te Tiriti o Waitangi
Authors: Bradshaw Kerry , Pike Travis , Ruawai Sarah , Reweti Angelique
Published: December 2024

This is a reflection on Riverdale Primary School’s approach to teaching Te Tiriti o Waitangi using a student-centred, inquiry-based framework. Over a 10-week inquiry in the Pae Ake classroom (Year 2 & 3), students explored Te Tiriti o Waitangi not only as a historical document but as a living agreement with ongoing cultural and societal significance. As part of this learning, they created their own classroom tiriti, using the experience to engage with principles of democratic processes, leadership, and to immerse themselves in learning about tikanga Māori. The project incorporated practical activities, including developing negotiation skills, learning to compromise, working collectively, clearly communicating expectations, and participating in a ceremonial signing. This approach helped students build meaningful connections with the values and cultural foundations of Te Tiriti o Waitangi, while enhancing their understanding of the diverse relationships, worldviews, and perspectives involved in its creation. By integrating lessons with interactive classroom experiences, this reflection illustrates how student-centred inquiry can foster understanding of Te Tiriti o Waitangi’s ongoing relevance, supporting bicultural learning in an Aotearoa New Zealand primary school context. Riverdale Primary provides an example of how student-centred inquiry can create inclusive and culturally responsive educational practices, fostering connections between students, their community, and the principles of Te Tiriti o Waitangi.

Caracas, Departure City: Urban planning after emigration and collapse
Authors: Gzyl Stefan
Published: December 2024

The recent deterioration of living conditions in Venezuela has resulted in an unprecedented migratory crisis, infrastructure collapse, and institutional decline. In the middle of this complex situation, migrants’ left-behind properties are being transformed into new uses. These changes often contradict zoning regulations, prompting a series of legal, social, and spatial strategies to conceal them. This article examines ongoing spatial and programmatic transformations of vacant homes in Caracas, the country’s capital, framing these changes within disciplinary discourses of shrinking and departure cities and in a specific experience of collapse that shapes daily life in the city. The article studies spatial transformations in terms of their material conditions and the opaque and informal procedures that produce them, describing the process from the point of view of various actors, from architects and entrepreneurs to local residents and planning authorities. Through interviews, site visits, and photographic documentation, the article describes the challenges and possibilities for social organization and institutional renovation in a climate of emigration and uncertainty.
An Upper Devonian Kadzielnia-type carbonate buildup in Skrzelczyce Quarry, southern Holy Cross Mountains (Poland)
Authors: Łuczyński Piotr , Pedrycz Olgierd
Published: December 2024

In Skrzelczyce Quarry, located in the southern part of the Holy Cross Mountains in central Poland, a large Upper Devonian carbonate mound is exposed. The Skrzelczyce mound, developed as massive and faintly bedded limestones, measures nearly 100 m in lateral extent and over 20 m in thickness, and laterally passes into coral-rich biostromal limestones belonging to the Sitkówka Beds. Four facies have been identified within the massive limestone unit: stromatactis-bearing limestones with scarce macrofossils (M1), macrofossil-rich limestones (M2), stromatoporoid-microbial limestones (M3), and limestones with fenestral structures (M4). These facies indicate varying depositional conditions and microbial activity, reflecting a complex interplay of environmental factors. The mound’s lithological features and spatial facies distribution resemble the late development stage of Devonian atolls in the Ardennes. This analogy suggests that the initial mound setting at Skrzelczyce might have been at depths of 30–60 m, in a moderate energy zone. The mound, composed predominantly of polygenetic biomicrite with a significant presence of laminar stromatoporoids and corals, features various forms of stromatactis, some typical and others related to sediment winnowing or to shelter cavities. The foraminiferal assemblages, along with lithostratigraphic correlation, suggest that the Skrzelczyce mound may belong to the lower to middle Frasnian, although the precise age remains uncertain due to the lack of conodont dating. The Skrzelczyce mound aligns with the definition of the Kadzielnia Member, and particular facies from Skrzelczyce can be matched with those described from the Kadzielnia Quarry. The structure outcropping in Skrzelczyce is the second largest Upper Devonian carbonate buildup after Kadzielnia in the Holy Cross Mountains, and the largest on the southern edge of the Kielce carbonate platform.
Palaeoenvironmental indices (calpionellids, gamma-ray spectrometry, magnetic susceptibility) in the Berriasian of the Tisza Mega-unit (Lipse-tető section, Mecsek Mts, Hungary) and the Central Western Carpathians (lower Sub-Tatric succession, Tatra Mts, Poland) – a comparison

Published: December 2024

Calpionellid stratigraphy, magnetic susceptibility (MS) and gamma-ray spectrometry (GRS) have been investigated in the Berriasian pelagic limestones of ca. 21 m thick interval from the Lipse-tető section (Mecsek Mts, southern Hungary, Tisza Mega-unit). The section covers the lower and upper Berriasian (Calpionella and Calpionellopsis Zones respectively), however due to a thrust fault, the upper part of the Calpionella elliptica Subzone and the lower part of the Calpionellopsis simplex Subzone (lower/upper Berriasian boundary interval) were not documented. Reslults of GRS measurements reveal contrasting trends, with low detrital input (K, Th) and elevated Th/K ratio through the lower Berriasian, as well as relatively high detrital input and decreased Th/K ratio within the upper Berriasian. The differences occur also in the calpionellid frequencies and species richness: assemblages rich in Calpionella alpina dominate in the lower Berriasian, whilst more diversified yet less abundant associations characterize the upper Berriasian. Trends in palaeoenvironmental proxies correspond well with data from the Lower Sub-Tatric succession (Pośrednie-Rówienka composite section, Tatra Mts, Poland). The palaeoenvironmental change between the early and late Berriasian is most probably related to palaeoclimate (arid to humid transition), and fertility (from oligo- to mesotrophic regime). Trends documented in Th/K ratio might have been controlled by the intensity of aeolian transportation. As revealed by previous studies, the consistent record of palaeoenvironmental changes in both the Tisza Mega-unit and the Central Western Carpathians might be observed also in the middle Jurassic sediments.
A prospective pilot study of kidney-specific biomarkers to detect acute kidney injury after cytoreduction and hyperthermic intraperitoneal chemotherapy
Authors: Chen Chao-Yu , Wang Ting-Yao , Chang Hung-Yu , Chen Min-Chi , Yang Lan-Yan
Published: December 2024

Background

Acute kidney injury (AKI) is a critical morbidity after cytoreduction and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC).

Objective

This study was conducted to investigate the use of kidney-specific biomarkers to evaluate the diagnostic accuracy of post-HIPEC AKI.

Methods

Patients who received CRS/HIPEC were prospectively enrolled in this study. We serially sampled urine neutrophil gelatinase-associated lipocalin (NGAL), serum cystatin C (sCyC), and β2 microglobulin (sβ2-MG) on the day before CRS/HIPEC and then 2 h, 1 d, 2 d, 3 d, and 7 d after CRS/HIPEC. The primary outcome was the occurrence of AKI during the first 7 d. The areas under the receiver operating characteristic curve (AUCs) were calculated to evaluate the detection performance.

Results

A total of 75 patients were eligible, of whom 5 (6.7%) fulfilled the criteria of AKI during the study period (AKI group) and 70 did not (non-AKI group). No significant differences were observed in these biomarkers between the two groups, except for sβ2-MG on day 3 (P = 0.025). Regarding changes in biomarker concentrations, the AKI group had a significantly higher concentration range of sCyC on day 3 (P = 0.009) and sβ2-MG on day 1 and day 3 (P = 0.013 and 0.019).

Conclusions

This is the first prospective study to evaluate the value of kidney-specific biomarkers in patients after CRS/HIPEC. We found that AKI cannot be predicted by simply using the absolute measurements of these biomarkers because of the heterogeneous characteristics of the patients.
Influence of blood thiosulfate produced by postmortem changes for the diagnosis of hydrogen sulfide poisoning in forensic autopsy
Authors: Suzuka Masaaki , Jin Shigeki , Takeuchi Akiko , Murakami Manabu , Takahashi Keiko , Matoba Kotaro
Published: December 2024

Background

Thiosulfate concentration in blood is an important indicator for the diagnosis of hydrogen sulfide poisoning. It may also be detected at high levels in postmortem decomposition cases.

Objectives

To determine the effect of postmortem decomposition on blood thiosulfate concentration and define precautions for diagnosing hydrogen sulfide poisoning based on thiosulfate concentration.

Methods

A total of 57 cadavers (37 males and 20 females) of non-hydrogen sulfide poisoning-related deaths that underwent forensic autopsy in our department between 2016 and 2019 were classified into the non-decomposed (19 cases), partially decomposed (19 cases), and severely decomposed (19 cases) groups based on forensic findings. Blood samples collected from each case were analyzed for thiosulfate concentration using liquid chromatography–tandem mass spectrometry.

Results

The mean concentration of thiosulfate detected in the blood was 70.9 (10.5–266.6) μmol/L in the severely decomposed group, 16.3 (0.1–52.7) μmol/L in the partially decomposed group, and 1.1 (0.1–3.6) μmol/L in the non-decomposed group. There was a statistically significant difference between each of the 3 groups (P < 0.01).

Conclusions

Previous studies have reported a blood thiosulfate concentration of >14 μmol/L in hydrogen sulfide poisoning cases and <4 μmol/L in normal cases. Thus, thiosulfate concentration is believed to have a significant impact on the diagnosis of hydrogen sulfide poisoning. This study revealed that postmortem decomposition produced thiosulfate in the blood, and the concentration of thiosulfate was often as high as that observed in cases of hydrogen sulfide poisoning-related death. In addition to cases of advanced decomposition, an increase in thiosulfate concentration was also observed in cases of partial decomposition. Therefore, when measuring thiosulfate concentration as an indicator of hydrogen sulfide poisoning, it is necessary to carefully consider the influence of decomposition.

Published: December 2024

The osteogenic process is a complex and dynamic biological phenomenon essential for the initial formation of bones during embryonic development and the continuous remodeling and repair of bones throughout an individual’s life. It involves coordination of various cell types, signaling pathways, and environmental factors to ensure proper bone formation and maintenance. The main role in this process belongs to bone marrow cells and peripheral blood cells. This paper provides an overview of currently available literature data about different contributions of bone marrow cells and peripheral blood cells to the osteogenic process. Focusing on their differentiation, signaling pathways, and interactions within the bone microenvironment this article aims to provide a comprehensive understanding of how these cells orchestrate the osteogenic process, offering insights into their therapeutic potential. Understanding these complex cellular interactions is crucial for the development of advanced therapeutic approaches in regenerative medicine and orthopedics, which will ultimately improve outcomes in patients with bone defects and bone-related disorders.

Reactive oxygen and nitrogen species (RONS) play a crucial role in the pathogenesis of various chronic diseases, including cancer, by reacting with fundamental biomolecules. While conventional anticancer treatments such as ionizing radiation and chemotherapy have significant adverse effects, some medicinal plants exhibit free radical scavenging and anticancer activities. Spilanthes acmella L., commonly known as the toothache plant, is reported to have various bioactive compounds with antioxidant and anticancer properties. The aim of this study was to investigate and evaluate antiproliferative potential of Spilanthes acmella ethanolic extract on human cervix adenocarcinoma (HeLa) and human myelogenous leukemia (K562) cancer cell lines. The stock solution of Spilanthes acmella extract was prepared in ethanol at concentration of 1 mg/mL and diluted with complete nutrient medium RPMI-1640. The medium was supplemented with 3 mM l-glutamine, 100 μg/mL streptomycin, 100 IU/mL penicillin, 10% heat-inactivated fetal bovine serum (FBS), and 25 mM Hepes, adjusted to pH 7.2. Cell survival was determined by the MTT assay 72 hours post-treatment. The IC50 values were calculated using a dose-response growth curve. The S. acmella ethanolic extract demonstrated significant cytotoxic (antiproliferative) effects on both HeLa and K562 cancer cell lines. The extract exhibited higher cytotoxicity towards K562 cells, with an IC50 value of 29.1 µg/mL, compared to HeLa cells, which had an IC50 value of 48.8 µg/mL. Spilanthes acmella extract possesses considerable potential as an anticancer agent and warrants further in vivo investigations to confirm its efficacy.

Dogs act as definitive hosts for several diseases caused by protozoa, some of which are zoonotic. Due to their close contact with humans and other animals, they play a crucial role in the transmission of these diseases. Although infection with Neospora caninum or Leishmania infantum is not a determining factor for another, co-infection with these protozoa can aggravate clinical signs and increase the mortality rate. Though, there are reports of success in the treatment of neosporosis, the prognosis is generally considered unfavorable, especially in young dogs. The objective of this study is to report a case of infection by both protozoa in a dog treated at a university veterinary hospital, highlighting the clinical remission of nervous signs of neosporosis after treatment with the combination of sulfadoxine and clindamycin, followed by reduction of clinical signs of canine leishmaniasis (CanL) with treatment with miltefosine and allopurinol. Despite the worse prognosis for co-infection with N. caninum and L. infantum, the dog presented remission of neurological signs and a reduction in parasite load and clinicopathological signs associated with CanL.

The public service works to provide frontline and vital services to meet the needs of the people of Ireland. Working on behalf of the government in a diverse range of organisations, public servants play an established role in the economic and social life of this country. The public service has grown and evolved to take advantage of opportunities, address new challenges, and meet the changing needs and expectations of the people of Ireland. Since 2011, the Department of Public Expenditure, NDP Delivery and Reform, has led a dedicated programme for reform and transformation, used its role and functions to enhance governance, build capacity and delivery effectively, working with the full range of public service bodies to build a more unified and agile public service. In 2023, the department published Better Public Services, a strategy that lays out the current framework and programme of transformation up to 2030, which is delivering tangible outcomes in improved public services, living standards and infrastructure in Ireland.
Civil service post-war policy debates, Department of Finance orthodoxy and the contours of the modern Irish economy
Authors: Barry Frank
Published: December 2024

Many share Michael Mulreany’s interest in the processes associated with the outward reorientation of the Irish economy from the mid-to-late 1950s through to European Economic Community accession in 1973. The Irish case is unusual by international standards in the importance accorded to the policy advice that emanated from within the civil service. While much of the historical focus has been on the Whitaker report of 1958, the contribution of which is celebrated in the 2009 work edited by Mulreany, the Department of Finance did not win all of the crucial debates on outward reorientation in which it was engaged. In particular, it had opposed the introduction in 1956 of export profits tax relief, the origin of the low corporation tax regime that remains in place to this day. This paper revisits the policy positions of the Departments of Finance and Industry and Commerce over the post-war decades and traces the foreign direct investment intensity of the modern Irish economy to the outcome of these debates.
An Assessment of Geotechnical Characteristics of Gharraf Oil Field Area Using Electrical Resistivity Test
Authors: Shaia Hussein A.
Published: December 2024

Geotechnical characteristics of soil are very important for civil applications and engineers because the structures almost construct and built on the ground such as high buildings, towers, bridges, tunnels and others on the soils. Electrical resistivity (ER) measurements are nowadays widely used to evaluate the geotechnical characterization of soil as they are fast, time-consuming and costly and non-destructive. This article provides the data of soil electrical resistivity measurements carried out on different zones and sites in Gharraf oil field area (northwestern part of the Thi-Qar governorate in the south east of Iraq). In this study the analyses of the obtained data were carried out to propose a new empirical quantitative correlation between soil resistivity and geotechnical characteristics. The improved empirical relationships reflect a very good correlation and it were found that the electrical resistivity of soil has a significant assessment and good fitting with the some of important geotechnical parameters. It was also concluded that the electrical resistivity method which has an advantage over other soil investigation methods that saving and reduce cost. Finally, the new generated empirical equation can be used to evaluate the ultimate bearing capacity of the soil rather than using the traditional widely used equations which require several inputs coefficients calculated using the extensive laboratory and field works. However, the results showed a good and more reliable correlation between soil electrical resistivity and some geotechnical characteristics for the studied region soil.
Assessment of the Numerical Behavior of Remolded and Undisturbed Clayey Soil

Published: December 2024

The simulation of soil behavior using finite element analysis depends mainly on the input parameters considered in analysis, moreover, in the case of clayey soil, most of the experimental studies for small models are performed on remolded samples because of difficulty of providing undisturbed soils. This leads to unreal results for numerical analysis as the validation process of numerical results is performed on remolded sample.

It was conducted experimental work on remolded clay including load-settlement tests of model footing at three states on undrained cohesion (cu), and then performed unconfined compression tests at the same undrained cohesion. After that, performing numerical modeling of the model footing from the data of unconfined compression tests.

It was observed that the value of the modulus of elasticity in clay from unconfined test considering the initial tangent is low for remolded state compared to the findings of the previous research.

Moreover, great care must be taken in selecting the elasticity modulus in performing the numerical analysis of the clayey soil, however, for undisturbed clay it is greater than remolded, the difference in the value is up to two times for stiff clay in the case of large scale footing, while it was reaches about four times.

Published: December 2024

The presence of expansive clay causes roads to undergo damage such as wavy, cracked, and even potholes. This type of soil shows that the soil is prone to swelling and shrinking. A base soil handling method against the effects of swelling and shrinking is chemical soil stabilization such as mixing the soil with lime, cement or additional materials. In this study, the stabilization method used was the fly ash and bottom ash geopolymerization reaction. Fly ash and bottom ash is an effective alternative to replace cement. Fly ash and bottom ash with addition of alkali activators of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) can serve as a binder similar to cement. This study aimed to improve the physical property and mechanical property tests of the soil such as bearing capacity and swelling potential as a requirement for subgrade. All physical property test results revealed that using fly ash-bottom ash geopolymer paste can improve qualities such as specific gravity, Atterberg limit, and grain size to improve expansive clay soil. Likewise, the mechanical property test results showed that the subgrade stabilized with fly ash-bottom ash geopolymer can increase its strength to surpass the requirements for road subgrades.
