Routine left atrial appendage closure: a retrospective analysis of mid-term outcomes
Authors: Komarov R.N. , Shevyakin D.V. , Solovyev Ye.B. , Kulikov N.V.
Published: September 2023

Background: There is strong evidence that stroke associated with atrial fibrillation (AF) has a cardioembolic origin. Given that the main source of thrombi in such patients is the left atrial appendage (LAA), there is a prospect of its closure becoming an adjunct or alternative to lifelong anticoagulant therapy.Objective: To evaluate the long-term effectiveness of routine LAA closure for ischemic stroke (IS) prevention in patients who underwent cardiac surgery with cardiopulmonary bypass (CPB).Methods: Our retrospective single-center study included patients who underwent cardiac surgery with CPB within 3 years. All participants were older than 18 years. The exclusion criteria: lack of information on the long-term outcomes; hemodynamically significant lesion of brachiocephalic vessels; porcelain aorta; infective endocarditis; history of malignant neoplasms, autoimmune diseases, and systemic vasculitis; acute coronary syndrome, repeated open heart surgery, and minimally invasive procedures. The selected patients were divided into 2 groups. Group 1 included patients who underwent concomitant LAA closure. Group 2 consisted of patients with intact LAA. We further divided patients based on whether they had preoperative AF or not. The primary end point was IS. The secondary end points were survival, perioperative myocardial infarction and AF, CPB and aortic cross-clamp time, number of resternotomies for bleeding, length of stay in the intensive care and cardiac surgery units.Results: After the primary analysis and use of exclusion criteria, we formed an LAA closure group (216 patients) and a group with intact LAA (179 patients). Among 129 patients with preoperative AF, concomitant LAA closure was performed in 69 patients and was not performed in 60 patients. Among 266 patients with no history of AF, this procedure was performed in 147 patients and was not performed in 119 patients. Multivariable Cox regression analysis included all the patients and showed that LAA closure was an independent predictor of decrease in IS incidence (hazard ratio, 0.20; 95% CI, 0.06-0.62; P = .006). At the same time, the procedure lost its benefits when patients with AF were excluded from the analysis. There were no differences in the secondary end points.Conclusion: LAA closure is an effective and safe method for long-term IS prevention in patients with AF operated on using CPB. The use of this procedure as a routine addition to the main cardiac surgery is not viable.

COMPETITIVENESS INDEX OF PENINSULAR MALAYSIA'S NORTHERN BORDER DISTRICTS
Authors: Abdullah Jamalunlaili , Danial Muhammad Hakim , Abdul Khalid Mazrina , Ab Rahman Abdullah , A Karim Azren
Published: September 2023

Competitive cities are known for their substantial economic growth, high incomes, and the ability to attract foreign investments. While a strong economy is crucial, other factors such as effective governance, efficient transportation, adequate housing, social inclusivity, and environmental sustainability also contribute to a city's competitiveness. This paper aims to assess the economic competitiveness of border districts in northern Peninsular Malaysia. Border cities hold significant importance following their proximity to neighbouring countries, subsequently offering advantages in terms of trade opportunities, cultural exchange, diplomatic relations, security, and socio-cultural integration. This research employed the quantitative method to measure the competitiveness level of 10 districts using economic and socioeconomic statistical data from the Department of Statistics Malaysia. The results indicated a distinct disparity among the districts along the Malaysia-Thailand border. In particular, the western districts of Perlis and Kubang Pasu displayed a higher level of economic development compared to the rural eastern districts due to their economic diversity and close proximity to industrial hubs such as Penang, Sungai Petani, and Songkhla in Southern Thailand. Furthermore, the strategic locations of the busiest international entry points, Bukit Kayu Hitam and Padang Besar, contribute significantly to the importance of logistics in these areas. In contrast, the middle and eastern districts heavily rely on agricultural activities, resulting in lower average incomes and higher poverty rates.
LAND SUBSIDENCE DYNAMICS IN MALAYSIA BASED ON TIME-SERIES VERTICAL DEFORMATION USING MODIFIED D-INSAR SENTINEL-1
Authors: Julzarika Atriyon
Published: September 2023

Land subsidence in urban areas is geohazard that can be caused by tectonic movements, changes in aquifer networks, or anthropogenic activities such as excessive groundwater extraction, mining, tunnelling, and plantations. The degree of land subsidence can be monitored using time-series vertical deformation data extracted from Sentinel-1 satellite imagery using the modified D-InSAR method. This study aims to determine the land subsidence dynamics of 16 cities in Malaysia based on time-series vertical deformation data, including Kota Bahru, Kuala Terengganu, George Town and Butterworth, Alor Setar, Kangar, Ipoh, Seremban, Malacca, Kuala Lumpur, Putra Jaya, Shah Alam, Kuantan, Johor Bahru, Kinabalu, Bandar Labuan (Victoria), and Kuching. The time-series vertical deformation data used in this study were extracted between 2014-2022. Negative values of vertical deformation indicate that land subsidence is occurring, while positive values of vertical deformation are indicative of regional uplift. The overall rate of land subsidence in Malaysia is between -0.5 cm to -6.0 cm, while the average uplift rate is between +0.5 cm to +4.5 cm. An analysis of the data extracted reveals that the city that is most vulnerable to land subsidence is Johor Bahru, followed by Kuala Terengganu, Seremban, Kuala Lumpur, Shah Alam, Malacca, and Kuantan, while the city that has the lowest risk of land subsidence is Kangar. In contrast, cities that are vulnerable to regional uplift are Kinabalu and Bandar Labuan (Victoria). The results of this study can be used to guide urban planning initiatives, allowing them to consider any threats that might be posed by land subsidence.
Histomorphological study of tongue in Indigenous peacock (Pavo cristatus)
Authors: Mohammed Hadaf H. , Hamza Luay O.
Published: September 2023

The current study aimed to examine the histomorphological features of the oral salivary ducts and the peacock tongue (Pavo cristatus) of this species. In this study, eight healthy adult peacocks were used after collecting them from a commercial market in Baghdad to investigate and describe the tongue in these bird species. After being euthanized, they were killed by cutting off the major neck blood vessels and bleeding until death; the tongue was identified. The tongue was the sharp end, elongated, somewhat triangular, and measured 8.2 mm. The apex, trunk, and base are its three sections. There are 4 to 5 layers of big conical papillae on the area where the root and body converge. Without gustatory papillae, the dense keratinized epithelium stratified squamous epithelia that lined the dorsal surface and were sparse on the ventral surfaces. The body and tongue root contain cells of the epithelium. It was supported by hyaline cartilage as a short plate. Lingual salivary glands situated anterior and posterior are superficial branch tubuloalveolar glands. This research was conducted at the University of Baghdad/ College of Veterinary Medicine in the Anatomy and Histology Department. Our result concluded that modifying the bird tongue, papillae distribution, and mucosa epithelium histological features is mainly restricted to feeding types that also have similarities with other avian species.

La pluralidad de fuentes del régimen económico del matrimonio
Authors: Fajardo Montoya Camelia
Published: September 2023

This paper is dedicated to the analysis of the plurality of sources of the economic regime of marriage in the absence of regulation of the conventional regime in the Cuban family legal system, since our legislation only assumes the legal and mandatory economic regime, without any margin for the autonomy of the will of the spouses. Hence, a theoretical foundation is made regarding the need for the implementation in Cuba of the plurality of sources of the economic regime of marriage in the family law in view of the new social and family context.

“The Situation Will Most Likely Turn Ugly”: Corporate Counter-Insurgency and Sexual Violence at a Canadian-Owned Mine in Guatemala
Authors: Granovsky-Larsen Simon
Published: September 2023

This paper offers a window into the terrain of corporate influence over violence in the mining industry. The research draws on over 300 pages of internal communications and other corpo-rate documents, which were produced by Vancouver-based Skye Resources and released pub-licly as an affidavit in a civil court case in Ontario, Canada. The documents demonstrate the roles of mining company executives and their collaborators in coordinating events that led to the gang rape of eleven Maya Q’eqchi’ women in Guatemala during a 2007 land eviction. Ana-lyzing the documents through a framework of corporate counter-insurgency (co-COIN), the pa-per explores the importance of international consultants and local elite networks in co-COIN campaigns. The case study explored in this paper contributes to the theorization of public-pri-vate repressive forces within co-COIN. The research also offers a visual tool to map actors in other instances of mining violence, which is intended for use by both academic researchers and anti-mining social movements.
Neoliberal Populism in Ontario: Premier Doug Ford’s Strategic Politics
Authors: Luccisano Lucy , Maurutto Paula
Published: September 2023

The 2018 election of Premier Doug Ford and the Progressive Conservative (PC) government ushered in a new era of neoliberal populism in Ontario, Canada. Ford’s election platform, titled a “Plan for the People,” resonated with the business elite who supported his free-market reforms but also with middle-class and blue-collar workers living in suburban and northern areas of the province. The article examines how Ford positioned his rivals as “out of touch” members of the political and cultural urban elite, responsible for a spiralling deficit that would economi-cally burden hard-working people. Unlike many other right-wing populist leaders, who have relied on xenophobic or anti-immigrant narratives, we argue that Ford’s populist stance is dema-gogic and pragmatic. This enabled him to pivot and shift his political strategy to amass support from a diverse range of economic, racial, ethnic, and religious groups, including new immigrants. We draw on newspaper articles, public documents and reports, as well as thirteen interviews with politicians, teachers and civil servants. The article highlights how Ford’s government operated to weaken democratic institutions through measures such as “strong mayor powers,” invoking the notwithstanding clause, as well as undermining the public sector. We trace how Ford’s populism undermined public education through overt and subtle measures that weaken school boards and unions while advancing privatization. We show how Ford bypassed intermediaries, in this case, school boards and teachers’ unions, and appealed directly to “the parents” through the media and employed cli-entelist strategies such as cash transfers under the guise of “parental choice” to hollow out public education. The analysis demonstrates how Ontario stands out as a unique case study for exam-ining neoliberal populism in Canada and North America.

Debunking the Falsehoods of Historical Interpretations: Arnold Spekke on George Kennan’s “Soviet-American Relations, 1917–1920. The Decision to Intervene”
Authors: Selga Marika
Published: September 2023

In the spring of 1958, Arnold Spekke, Charge d’Affaires in Washington D.C., having read George Kennan’s book “Soviet-American Relations, 1917–1920. The Decision to Intervene” decided to write a comment on certain facts expressed in the book. He concentrated on the description of the execution of Czar Nicholas II and his family, as well as the fact that the book did not mention the Latvian units that fought under Allied leadership, namely, the Troitsk battalion as part of the 3rd Czechoslovak Division. Spekke also submitted a letter written in 1928 by Nikolai Sokolov’s assistant, Captain Pavel Bulygin, in which it was confirmed that there were no Latvians among the shooters. Kennan in his response assured that his goal had only been to emphasize the cruelty with which the murder was committed. The preparation of comments contributed to the efforts of Latvians in exile to focus on writing down memories and studying Latvian history.

Latgales un Latgales latviešu vēsture līdz 20. gadsimtam attīstījās līdztekus, taču no pārējās latviešu tautas vēstures zināmā mērā atšķirīgos apstākļos, tādēļ Latgales latviešu nacionālā atmoda un apvienošanās ar pārējo tautu vienotā Latvijas valstī noritēja ar sarežģījumiem. Minētie procesi vēl līdz šim laikam nav pilnībā izpētīti, tādēļ jebkurš vēstures avots un tā analīze var būt nozīmīgs. Šajā gadījumā tas attiecas uz karavīru, sabiedrisku darbinieku, politiķi Jāni Rubuli, kurš no 1917. gada atradās sabiedriski politisko norišu epicentrā, aktīvi piedaloties Latgales kongresā, Latviešu strēlnieku pulku izpildkomitejas (Iskolastrela) Latgaliešu strēlnieku sekcijas darbā, Latvijas Neatkarības karā, Satversmes sapulces un Saeimas darbībā, valsts politiskajā un saimnieciskajā dzīvē kopumā, visbeidzot – trimdā Rietumos pēc Otrā pasaules kara.

Objetivo: establecer la relación entre el consumo de alimentos considerados como factores de riesgo para cáncer gástrico y la presencia de cambios tróficos de la mucosa gástrica.
Materiales y métodos: estudio de corte transversal. Se incluyeron los pacientes mayores de 18 años admitidos para realización de endoscopia digestiva superior con toma de biopsias que respondieron adecuadamente una encuesta de antecedentes personales y hábitos de alimentación. Se excluyeron aquellos con antecedente de cáncer gástrico o resección quirúrgica gástrica por cualquier motivo. Se estimó la asociación entre las variables de alimentación y la presencia de cambios tróficos de la mucosa gástrica.
Resultados: en una población de 1096 pacientes, el promedio de la edad fue 51 años (desviación estándar [DE]: 15,5), y correspondió en un 59% a mujeres. Se identificaron cambios tróficos de la mucosa gástrica en 173 pacientes (15,8%). No se obtuvo asociación estadística entre las variables independientes de hábitos de alimentación, obesidad y Helicobacter pylori positivo frente a la variable “cambios tróficos”, a diferencia de la variable “antecedente familiar de cáncer gástrico” (odds ratio [OR]: 1,49; intervalo de confianza [IC] 95%: 1,03-2,17; p = 0,036). Se obtuvo 1 caso de displasia de alto grado en la población estudiada (0,91 casos en 1000 pacientes).
Conclusiones: no se estableció una asociación entre los hábitos de alimentación y la presencia de cambios tróficos de la mucosa gástrica en la población estudiada. El antecedente familiar de cáncer gástrico se muestra como un factor de riesgo estadísticamente significativo para el desarrollo de cambios de atrofia, metaplasia o displasia.

La obesidad es una epidemia global, según la Organización Mundial de la Salud (OMS) se define como una acumulación anormal o excesiva de grasa que puede ser perjudicial para la salud, su incidencia está aumentando de forma alarmante en los países en desarrollo. Asimismo, es un factor de riesgo importante para el desarrollo de enfermedades crónicas como la diabetes mellitus tipo 2, hipertensión arterial, enfermedad coronaria, enfermedad del hígado graso no alcohólico y trastornos musculoesqueléticos como la osteoartritis; además, se han encontrado asociaciones entre la obesidad y el desarrollo del cáncer de próstata, hígado, vesícula biliar, riñón, colon, endometrio, mama y ovarios. La cirugía bariátrica y metabólica es el tratamiento más eficaz para la obesidad mórbida y sus comorbilidades, esta cirugía puede reducir la mortalidad general en un 40% a los diez años por desenlaces cardiovasculares, diabetes o cáncer, como también mejorar enfermedades metabólicas como la diabetes tipo 2.
Temporal turnover in species' ranks can explain variation in Taylor's slope for ecological timeseries
Authors: Ghosh Shyamolina , Matthews Blake
Published: September 2023

The scaling exponent relating the mean and variance of the density of
individual organisms in space (i.e. Taylor’s slope:
z) is well studied in Ecology, but the analogous
scaling exponent for temporal datasets (z) is
underdeveloped. Previous theory suggests the narrow distribution of
z (e.g. typically 1 - 2) could be due to
interspecific competition. Here, using 1,694 communities time series, we
show that z can exceed 2, and reaffirm how this can
affect our inference about the stabilizing effect of biodiversity. We
also develop new theory, based on temporal change in the ranks of
species abundances, to help account for the observed
z distribution. Specifically, we find that
communities with minimal turnover in species’ rank abundances are more
likely to have higher z. Our analysis provides a
deeper mechanistic understanding of how species-level variability
affects our inference about the stability of ecological communities.
A Plate Motion Model of the Indo-Australian Tectonic Plate that Better Aligns with the Geodetic Coordinate System - Towards a More Precise Static Ellipsoidal Datum
Authors: Mccubbine Jack , Riddell Anna , Brown Nicholas
Published: September 2023

We present a class of “ellipsoidal rotation matrices” which can be
used to characterise tectonic plate motion; where geocentric Cartesian
coordinates travel along paths tangential to the ellipsoid. We contrast
them with conventional Euler pole plate motion models which are more
closely aligned with spherical coordinate systems and inherently induce
a change in geodetic ellipsoidal height. We demonstrate the use of each
in the Indo-Australian tectonic plate setting, which is known to move
approximately 7 cm/yr in a north-northeast direction. Geocentric Datum
of Australia 2020 (GDA2020) coordinates are “plate-fixed” static
coordinates obtained using a conventional Euler pole plate motion model
to align time dependent coordinates with the 2014 realisation of the
International Terrestrial Reference Frame (ITRF) at the epoch 2020.0. We
show that this Euler pole plate motion model can introduce ellipsoidal
height velocities of up to -0.2 mm/yr. This is small but systematic, so
pertinent for consideration with high accuracy vertical land motion
studies using GDA2020 coordinates. We further investigate the
comparative statistical accuracy of conventional Euler pole and the
ellipsoidal models with respect to characterising plate motion captured
in high quality GNSS data.
Automated seafloor massive sulfide detection through integrated image segmentation and geophysical data analysis: Revisiting the TAG hydrothermal field

Published: September 2023

Accessible seafloor minerals located near mid-ocean ridges are noticed
to mitigate projected metal demands of the net-zero energy transition,
promoting growing research interest in quantifying global distributions
of seafloor massive sulfides (SMS). Mineral potentials are commonly
estimated using geophysical and geological data that lastly rely on
additional confirmation studies using sparsely available, locally
limited, seafloor imagery, grab samples, and coring data. This raises
the challenge of linking in-situ confirmation data to geophysical data
acquired at disparate spatial scales to obtain quantitative mineral
predictions. Although multivariate datasets for marine mineral research
are incessantly acquired, robust, integrative data analysis requires
cumbersome workflows and experienced interpreters. Here, we introduce an
automated two-step machine learning approach that integrates automated
mound detection with geophysical data to merge mineral predictors into
distinct classes and reassess marine mineral potentials for distinct
regions. The automated workflow employs a U-Net convolutional neural
network to identify mound-like structures in bathymetry data and
distinguishes different mound classes through classification of mound
architectures and magnetic signatures. Finally, controlled source
electromagnetic data is utilized to reassess predictions of potential
SMS volumes. Our study focuses on the Trans-Atlantic Geotraverse (TAG)
area, which is amid the most explored SMS area worldwide and includes 15
known SMS sites. The automated workflow classifies 14 of the 15 known
mounds as exploration targets of either high- or medium-priority. This
reduces the exploration area to less than 7% of the original survey
area from 49 km2 to 3.1 km2.
Geogrid donatılı istinat duvarı yapımında kullanılan dolgu malzemesinin mühendislik özelliklerinin güvenlik katsayıları üzerindeki etkisi

Published: September 2023

Bu çalışmada, yapımı tamamlanmış ve hizmete açılmış bir karayolu güzergâhında bulunan geogridle güçlendirilmiş istinat duvarlarına ait tasarım parametreleri kullanılarak dolgu malzemesi için tahmine dayalı olarak seçilen içsel sürtünme açısı ve birim hacim ağırlık gibi parametrelerin geogridin kopmaya ve sıyrılmaya karşı güvenlik katsayıları üzerindeki etkileri incelenmiştir. Yapılan analizler sonucunda, içsel sürtünme açısı arttığında kopmaya ve sıyrılmaya karşı güvenlik katsayılarında artış meydana geldiği ve sıyrılmaya karşı güvenlik katsayılarının kopmaya karşı güvenlik katsayılarından daha yüksek çıktığı görülmüştür. Bu bakımdan tasarım hesaplarında, kopmaya karşı güvenlik katsayısının daha kritik olduğu ve tasarımı kontrol eden asıl faktörün kopmaya karşı güvenlik katsayısı olduğu sonucuna varılmıştır. Bununla birlikte, sıyrılmaya karşı güvenlik katsayısının kopmaya karşı güvenlik katsayısına kıyasla içsel sürtünme açısının değişimlerinden daha fazla etkilendiği görülmüştür. Örneğin, içsel sürtünme açısında %15’lik bir artış, kopmaya karşı güvenlik katsayısında yaklaşık %30 oranında bir artışa neden olurken, sıyrılmaya karşı güvenlik katsayısında, z = 1,2 m’de yaklaşık %310, z =10 m’de ise yaklaşık %60’lık bir artışa neden olmuştur. Dolgu malzemesinin birim hacim ağırlığındaki değişimlerin kopmaya ve sıyrılmaya karşı güvenlik katsayıları üzerindeki etkisinin yüksek olmadığı (sırasıyla yaklaşık %10 ve %3) görülmüştür. Kendi aralarında kıyaslandığında, dolgu malzemesinin birim hacim ağırlığındaki değişimlerin, kopmaya karşı güvenlik katsayısı üzerindeki etkisinin sıyrılmaya karşı güvenlik katsayısı üzerindeki etkisinden daha yüksek olduğu görülmüştür.

Aineistona käytetyt suositukset, joita on yhteensä viisi, on tarkoitettu informaatio-ohjauksen välineiksi. Ymmärrämme tutkimuksessamme sosiaalihuollon hyvinvointia tuottavana yhteiskunnallisena ympäristönä ja tehtävänä. Tarkastelemme sitä, miten sosiaalihuolto ilmaistaan yhteiskunnallisena tehtävänä laatusuosituksissa. Kyseessä on laadullinen tutkimus, jonka analyysi ja tulkinta pohjautuvat hermeneutiikkaan ja lähilukuun. Analysoimme aineistosta hermeneuttisen lähiluvun keinoin avainsisältöjä, jotka vaihtelevat laatusuosituksesta toiseen. Sosiaalihuollon tuottama hyvinvointi tarkoittaa jokaisessa viidessä laatusuosituksessa eri tehtäviä. Analyysissa erottuivat sosiaaliset oikeudet, yhteiskunnan sopeutuminen ikääntymiseen, yhteinen suunnitelma työvälineenä, sosiaalihuolto yhteistyökumppanina ja sosiaalihuolto ongelmallisena. Laatusuosituksissa sosiaalihuollon yhteiskunnallinen tehtävä on sivuroolissa, ellei kokonaan syrjäytetty.
Is society fading away from elder services? Analysis of social care in quality recommendations
The article studies the concept of social care and the changes it has undergone in the quality of recommendation documents for elder services. Five documents were published between 2001 and 2020. The data consists of these documents that stand for service control and guidance within elder care. We understand social care as yielding well-being but also including significant societal functions such as promoting inclusion and equality. The research question is: how society and social care, and the societal in general, are described and defined in the documents of service control and guidance? The research design is based on qualitative analysis, and the application of principles of hermeneutics and close reading methods to discover key categories in each quality recommendation. Analysis indicates that the conceptualisation of well-being yielded by social care in the quality recommendation documents is versatile and inconsistent. The societal function of social care is defined as social rights (2011), societal adjustment to ageing (2008), mutual ageing strategy (2013), social care as a cooperation partner (2017), and social care as a problematic issue (2020). The societal function of social care seems to be fading away from elder services.

Published: September 2023

Surgical planning is essential, and its effectiveness depends on alignment with essential sub-processes such as supplies, bed management, intensive care unit and material sterilization center. Above all, one of the most relevant pieces of information when planning operating rooms is the duration of each surgical procedure. Therefore, the aim of this research is to present an approach to collect surgical procedure times using digital technology. METHOD: As for the research methodology, this article was developed within a qualitative interface and the action-research method was implemented. RESULTS: The results directly show that the proposed approach can effectively help hospital managers in the indicated context, and the proper use of this digital technology can optimize care, reduce waiting times and minimize the total number of surgeries canceled monthly. CONCLUSION: The conventional approach used in manufacturing, of timing processes on production lines, is still widely used, but within the operating room it is impractical and not very applicable. Therefore, this research presents an innovative tool to assist in the planning of surgeries, with regard to the collection of surgical procedures and, consequently, to improve the efficiency of hospital management in the context studied, through more effective surgical planning.

Poverty is a widespread social problem that affects many developing countries, including Indonesia. The province of West Sumatra has a relatively low poverty rate of around 5.92 percent, making it the third lowest on the island of Sumatra. However, there are several districts and cities in this province that still have many people living in poverty. Various factors such as income levels, social conditions, and access to education, can contribute to the poverty gap in various regions. Geographically Weighted Binary Logistic Regression (GWBLR) is used to examine the relationship between poverty and geographic factors. GWBLR is a statistical analysis technique that takes geographic variables into account when the response variable is categorical or dichotomous. This approach incorporates a bandwidth-dependent weighting function. By conducting a fit test using R software, it is known that the Fcount value is greater than the Ftable value, indicating a significant difference between the logistic regression model and GWBLR. The results show that the GWBLR model with Fixed Gaussian Kernel weights is the most effective in analyzing poverty in the province. This model shows the lowest Akaike Information Criterion (AIC) value. Furthermore, this study identifies the Life Expectancy Variable as a significant factor affecting poverty in certain districts and cities in West Sumatra Province in 2022.

Indonesia is a country prone to earthquakes. This is because the territory of Indonesia is located between the confluence of three tectonic plates (the Eurasian plate, the Indo-Australian plate, and the Pacific Ocean plate) and is also in the Ring of Fire. The number of earthquakes in Indonesia varies in each province due to the different characteristics of the location of the plates of each province in Indonesia. Earthquake disasters have a very detrimental impact on society, such as causing casualties, damaged houses or damage to public facilities. Therefore it is important to grouping the impact of earthquakes in Indonesia as a disaster mitigation effort in order to find out the characteristics of each province in each cluster. The grouping method used is Kohonen Self Organizing Maps (SOM). SOM is a high-dimensional data visualization technique in the form of a low-dimensional map. The results 3 clusters with the characteristics of each cluster. Cluster 1 consisting of 24 provinces has the characteristics of the highest number of earthquake incidents, the number of missing victims, the number of victims suffering and the number of damaged houses. Cluster 2 consisting of 7 provinces does not show any prominent characteristics of the cluster. Cluster 3 consists of 3 provinces with very prominent characteristics, namely the number of victims killed, the number of injured victims, the number of displaced victims, the number of damaged educational facilities, the number of damaged health facilities and the number of damaged worship facilities the most of the other clusters.

Classification is a method to estimate the class of an object based on its characteristics. Several learning algorithms can be applied in classification, such as Classification and Regression Tree (CART) and logistic regression. The main goal of classification is to find the best learning algorithm that can be applied to get the best classifier. In comparing two learning algorithms, a direct comparison by seeing the smaller prediction error rate may be possible when the difference is very clear. In this case, direct comparison is misleading and resulting inadequate conclusions. Therefore, a statistical test is needed to determine whether the difference is real or random. The results of the 5×2cv paired t-test sometimes reject and sometimes fail to reject the hypothesis. It is distracting because the changing of the error rate difference should not affect the test result. Meanwhile, the overall results of the combined 5×2cv F test show that the tests fail to reject the hypothesis. This indicates that CART and logistic regression perform identically in this case.

In the ethnically diverse nation of Indonesia, conflicts rooted in issues of Ethnicity, Religion, Race, and Inter-Group (SARA) have long been a persistent problem, particularly affecting ethnic Chinese who have faced marginalization and sociocultural challenges, including name changes and stereotypes. The Meranti Islands have been in the spotlight of the national media several times because of the various conflicts that occurred, both political conflicts and conflicts between ethnicities, tribes and even religions such as the burning of Chinese Ethnic Shophouses. These conflicts, driven by differences in interests and interference among groups, have sometimes led to tensions, discrimination, and even riots. The research aims to analyze Abdurrahman Wahid's political da'wah from the perspective of non-Muslim minority groups in the Meranti Islands Regency. This research is field research type. The research method uses qualitative methods. Data was collected through questionnaires and interviews and strengthened by a literature review. The research results show two thoughts regarding Islamic politics; first, 85% of the non-Muslim community in Meranty Island strongly supports Abdurrahman Wahid's Islamic political da'wah to be realized in public policies. The non-Muslim minority groups support Abdurrahman Wahid's political da'wah to maintain the Islamic taught about the rights and obligations of citizens and protect minority groups. With a percentage of 93%, they considered Abdurrahman Wahid to have carried out the function of Islamic teachings to do good deeds in a moderate and tolerant humanitarian and political life.

Published: September 2023

The Mediterranean Basin has been the starting point of many civilizations since prehistoric times. The political, commercial, economic, and cultural activities carried out in this region for centuries have played an important role in the states trying to dominate this region. Especially, the Eastern and Western Mediterranean basins on both sides of the north-south transition, on which Sicily is located, have formed a strong field of struggle throughout history. Sicily, the largest island of the Mediterranean, has witnessed the wars of many states with its position as a crossroads. One of them is the Franco-Dutch Struggle between 1672-1678. The battles of Messina, Stromboli, Augusta, and Palermo, which formed the Sicilian front of the war between 1674 and 1676, reveal the richest visual data of the race for dominance in the Western Mediterranean. Because these encounters are highly significant for the future of the Mediterranean, especially following the Battle of Lepanto. The aim of the article is to present the established dominance at this point through visual evidence. What is important here is that painters, by creating a pictorial template from evolving images due to shifting power dynamics, have applied this to scenes of warfare. Moreover, a crucial aspect is that these works have been produced in a contemporary timeframe alongside the battles. Furthermore, these paintings have not only served as pieces of art but also as political tools. In this article, the identified war scenes are discussed in a chronological order, without emphasizing technical distinctions. This way, symbolic connotations that revive the prideful aspect of the achieved victory are attempted to be brought back to memory. To a certain extent, the visual representation of the sentiment of heroism directed towards the past is highlighted, focusing on pictorial indicators.
A Study of Physical and Mechanical Properties using Kenaf Core as Coarse Aggregate Replacement in Concrete
Authors: Mohd Apandi Nazirah
Published: September 2023

Kenaf is well known for its one of the highest rankings of biomass producers compared to other fibre crops which excessive amounts of biomass could lead to contamination of soil due to its pollutants elements. Not only that, the high demand for aggregate for concrete production requires massive use of natural stone materials which leads to the destruction of the ecological balance of the environment. As in Malaysia, kenaf core is commonly used and available in abundance after the processing of kenaf stems for bast fiber production. Thus, this research aims to determine the physical and mechanical properties of kenaf core as fine aggregate replacement in concrete. There were 45 samples of the concrete cube of 100 mm x 100 mm with the percentage used of 0, 5, 15 and 25 % kenaf core replacement. A density test was conducted as well as a compressive strength test to obtain the objectives of the study. Findings reveal that the control sample still has the highest value of compressive strength of 34.7 MPa while 5 % of kenaf core concrete shows 28.50 MPa which slight decrease in the value in comparison. The value then gradually decreases as the percentage of the kenaf core increases. The density test also reveals that 25 % kenaf core shows the lowest value of density by 1419.78 kg/m3 compared to normal concrete. Thus, this indicates that the optimum percentage of kenaf core used was 5 % even though it still did not surpass 0 % concrete.
Comparative Study of Mechanical and Physical Properties of Rice Husk Filled Polyethylene Waste Composites
Authors: Din Siti Nor
Published: September 2023

Polyethylene (PE), a type of plastic, is utilized extensively in many different applications and has become a significant part of our daily life. However, numerous plastic product manufactures have a significant environmental impact. As a result, several approaches have been investigated in order to reduce waste disposal issues. Rice husk (RH), on the other hand, is a form of agricultural waste that contains lignocellulosic fiber that can be used as a filler in polymer composites. As a result, combining both PE waste and RH fiber could be a viable option for saving our world. The objective of this study was to ascertain the impact of different RH fiber loadings, including 5, 10, 15, 20, and 25 %, on the mechanical and physical characteristics of composites manufactured from used HDPE and LDPE materials. Due to inadequate bonding between the hydrophilic fiber and the hydrophobic polymer matrix, it was discovered that increasing the filler loading lowered the tensile strength, elongation at break, and impact strength of the composites. In comparison to RH/HDPE, the tensile strength of RH/LDPE composites showed a greater decline at 45 % at the highest loading of 25 % RH fiber. Both composites showed a 98–99 % decrease in elongation at break as a result of constrained chain elongation and mobility. Additionally, the impact strength value of RH/HDPE waste composites decreased by 43 % compared to 31 % for RH/LDPE waste composites. In contrast, the inclusion of fillers improved the modulus and density of the composites substantially. While the trends for RH/HDPE and RH/LDPE composites are similar, RH/HDPE waste composites demonstrated superior mechanical characteristics than RH/LDPE waste composites.
