A Comparative Study of Deep Learning Approaches for Human Action Recognition
Authors: Yiğit Gülsüm
Published: January 2025

Human Action Recognition (HAR) plays a crucial role in understanding and categorizing human activities from visual data, with applications ranging from surveillance, healthcare to human-computer interaction. However, accurately recognizing a diverse range of actions remains challenging due to variations in appearance, occlusions, and complex motion patterns. This study investigates the effectiveness of various deep learning model architectures on HAR performance across a dataset encompassing 15 distinct action classes. Our evaluation examines three primary architectural approaches: baseline EfficientNet models, EfficientNet models augmented with Squeeze-and-Excitation (SE) blocks, and models combining SE blocks with Residual Networks. Our findings demonstrate that incorporating SE blocks consistently enhances classification accuracy across all tested models, underscoring the utility of channel attention mechanisms in refining feature representation for HAR tasks. Notably, the model architecture combining SE blocks with Residual Networks achieved the highest accuracy, increasing performance from 69.68% in baseline EfficientNet to 76.75%, marking a significant improvement. Additionally, alternative models, such as EfficientNet integrated with Support Vector Machines (EfficientNet-SVM) and ZeroShot Learning models, exhibit promising results, highlighting the adaptability and potential of diverse methodological approaches for addressing the complexities of HAR. These findings provide a foundation for future research in optimizing HAR systems, with implications for enhancing robustness and accuracy in action recognition applications.

Authors: Yirenkyi Edmund
Published: January 2025

This review explores how philanthropy contributes to climate action in Atlantic Canada, a region facing threats from extreme weather events, rising sea levels, and scarcity of resources that impact local communities. While public and private sector funding is vital, philanthropy offers unique opportunities to support localized, innovative climate solutions. This review explores the current climate finance landscape, identifies the specific needs of Atlantic Canadian communities, and evaluates how philanthropic funding can bridge gaps in financing. It focuses on the impact of philanthropy on climate adaptation and mitigation efforts, emphasizing community resilience and sustainability. While philanthropy can drive positive change, challenges such as equitable resource distribution, fostering systemic change, and empowering marginalized communities must be addressed. Philanthropic organizations should transition from providing short-term, project-focused funding to supporting long-term, transformative initiatives. Collaborative partnerships between governments, businesses, and civil society are key to maximizing impact. Addressing these challenges and embracing innovative approaches will enable philanthropy to serve as a powerful catalyst for climate action, fostering a more environmentally stable future and able to withstand climate challenges for Atlantic Canada and beyond.

Authors: Muhammad Nur Effendi  , Suriagiri  , Mudhiah
Published: January 2025

This study explores the development of Islamic creed education in the era of Society 5.0, focusing on technology integration and the challenges faced. The method used is qualitative, with a case study analysis of several Islamic educational institutions and interviews with educators and parents. Data were collected through observation, in-depth interviews, and literature studies to understand the application of technology in creed education and its impact on the teaching and learning process. The results show that technology integration in Islamic creed education provides significant benefits in increasing the accessibility of teaching materials, enriching teaching methods, and facilitating better interaction between teachers and students. Technologies such as mobile applications, e-learning platforms, and visual aids have expanded the way teaching materials are delivered and made it easier for students to understand the concepts of the creed. However, significant challenges arise from resistance to change, concerns about negative impacts on Islamic values, and the need for educators to be trained to utilize technology effectively. This research emphasizes the importance of a careful and planned approach to integrating technology so that Akidah education remains relevant and aligned with religious principles while accommodating technological developments.
Angina with Non-obstructed Coronary Arteries and Invasive Diagnostic Testing in the Cardiac Catheterization Laboratory
Authors: Abbott J. Dawn
Published: January 2025

More than a third of patients who present to the cardiac catheterization laboratory for elective coronary angiography for a chronic coronary syndrome are found to have normal or nonobstructive coronary artery disease. Angina or ischemia with non-obstructive coronary arteries (ANOCA/ INOCA) is prognostically important and is associated with decreased quality of life and increasedcardiovascular morbidity. Chronic coronary syndromes are mediated by atherosclerosis, microvascular disease, and vasospastic disease at the epicardial and microvascular level. The severity of epicardial coronary disease is routinely evaluated with angiography and coronary physiology. A comprehensive invasive diagnostic assessment, however, is rarely pursued in patients determined to have non-obstructive coronary disease. In the modern cardiac catheterization laboratory, patients with ANOCA should be examined with flow assessment, intracoronary imaging, coronary flow reserve, microvascular resistance, and provocative testing to diagnose the mechanism of ischemia. Patients may have one or more endotypes including microvascular angina, microvascular spasm, or vasospastic angina with normal or non-obstructive coronary artery disease. This review provides an overview of the pathophysiology and catheterization lab invasive diagnostic testing that can guide the diagnosis and management of patients with ANOCA and discusses ongoing clinical trials.

Effects of exercise-based cardiac rehabilitation on left ventricular systolic and diastolic function in sub-Saharan African Patients
Authors: Diaba Gaye Ngone
Published: January 2025

Background: Cardiac rehabilitation (CR) represents a highly efficacious non-pharmacological intervention for cardiac patients. Yet, its effect on left ventricular systolic function remains controversial and there is a lack of data in sub-Saharan African patients. The aim of this study was to assess effects of exercise based cardiac rehabilitation on left ventricular systolic and diastolic function after cardiac rehabilitation in a black African population.

Results: A total of 103 patients with a male-to-female ratio of 1.64. The mean age was 56,37 yo ± 11,59. Most of the patients (83.5%) presented with dyspnea stage 2 to 3 of classification. Sedentary lifestyle and dyslipidemia were the predominant cardiovascular risk factors, in 90% and 76% of cases respectively. Coronary artery disease was the primary indication, accounting for 74.8% of cases. After cardiac rehabilitation improvement in both left ventricular ejection fraction [+ 17%, P 0.000] and stroke volume [+ 13.5 ml, P 0.00]. This improvement was particularly significant among patients with a left ventricular ejection fraction (LVEF) < 40%. Mean E/e’ ratio decreased significantly upon completion of cardiac rehabilitation [-2.91 pts, P 0.000]. Furthermore, 37.9% of patients had elevated left ventricular filling before CR against 5.9 % after CR (P 0.000).

Conclusion: Cardiac rehabilitation results in significant improvement in both systolic and diastolic left ventricular function in our population subset.
Ebstein’s Anomaly and Echocardiographic Features
Authors: Muthiah Ramachandran
Published: January 2025

Aim: To present the various echocardiographic spectrum of Ebstein’s malformation in adolescence and adults. Introduction: Ebstein’s anomaly has different anatomic and hemodynamic variables with clinical manifestations of cyanosis, right-sided heart failure and arrhythmias. The leaflet tethering and dysplasia, together with dilatation of the tricuspid valve ring, constitute the anatomic cause of tricuspid regurgitation observed in this condition.

Case reports: The spectrum of leaflet tethering from mild to extreme with varying degrees of tricuspid regurgitation were documented by echocardiography in a 16-year old cyanotic male with Ebstein’s anomaly associated with an atrial septal defect and mild low tricuspid regurgitation (TR), 22-year old acyanotic male with right-sided heart failure due to severe tricuspid regurgitation and an intact atrial septum, 55-year old aymptomatic female with moderate high tricuspid regurgitation. The extreme form was described as an ‘atretic’ membrane in a 28-year old cyanotic male and as a ‘blanket’ of leaflet tissue in a 30-year old cyanotic male.

Conclusion: Ebstein’s anomaly has to be suspected clinically in presence of cyanosis with a WPW (Wolf-Parkinson-White) or atrioventricular (AV) block pattern of ECG and its management is complex and must be individualized. RV (right ventricular) exclusion procedures are preferred in advanced cases.
Stress CMR VS Stress Echo: Real-world multimodal cardiovascular imaging for myocardial ischemia screening. Insights from the first phase of “Nancy Ischemia Registry”
Authors: Chati Zukaï
Published: January 2025

In a real world, the impact of different functional and anatomical imaging techniques is not really known.

Objectives

“Nancy Ischemia Registry” is a prospective registry, without inclusion or exclusion criteria, which analyzes the respective real impact and consequences of different functional and anatomical imaging techniques on major adverse cardiovascular events.

In a “first phase”, we compared two functional imaging techniques used in our center: Stress CMR and Stress Echo.

Materials & Methods

We consecutively included 169 patients in whom we performed Stress CMR and 687 patients in whom we performed Stress Echo.

Results

We detected myocardial ischemia in 59 patients by Stress CMR (35% of patients) and in 123 patients by Stress Echo (18% of patients).

Coronary angiography confirmed at least one significant lesion in 54 patients in the Stress CMR group (PPV 91%) and in 90 patients in the Stress Echo group (PPV 73%). In patients with at least one significant coronary lesion, coronary angioplasty was performed in 38 patients (64% of true positives) in the Stress CMR group versus 64 patients in the Stress Echo group (71 % of true positives).

Conclusion

Stress CMR has a better specificity than Stress Echo for the detection of myocardial ischemia. However, detection of myocardial ischemia by Stress Echo more often leads to coronary revascularization than by Stress CMR. This difference in this register is probably explained by a higher sensitivity of the Stress CMR for the detection of myocardial ischemia linked to less severe lesions, whereas the Stress Echo mainly detects more severe lesions.

Methotrexate in the Management of Ectopic Pregnancy: A Comparative Review of Single-Dose Versus Multi-Dose Protocols
Authors: Barem Zahraa Haider
Published: January 2025

Ectopic pregnancy ruptures account for five percent to ten percent of all pregnancy-related deaths and are the primary reason for maternal mortality throughout the first trimester of pregnancy, with a rate of nine percent to fourteen percent. An ectopic pregnancy is a gestational sac that implants somewhere other than the uterus. The implantation of an embryo outside the uterus, usually in the fallopian tube, is the essence of ectopic pregnancy. To aid in the passage of an egg and embryo by the fallopian tubes, smooth muscle contraction, and ciliary beat have been used. Damage to the fallopian tubes, typically caused by inflammation, can lead to tubal dysfunction and the retention of an embryo or ovum. The anti-metabolite methotrexate is most frequently used as an immunosuppressant in autoimmune illnesses and as a chemotherapy drug. This activity explains methotrexate's actions, side effects, and recommended dosage for treating a range of neoplastic conditions. The single-dose, 2-dose, and multi-dose methotrexate protocols are the most popular ones. Studied cases who are more likely to require additional doses due to medical treatment failure may benefit from the multi-dose strategy. To reduce side effects, the multidose protocol calls for the adding of folinic acid rescue in addition to methotrexate doses, which are alternated. This is because of how frequently the regimen is administered. Although the single dose was intended to cut down on visits, it frequently necessitates more care and follow-up.

Authors: Apostolov Zhivko
Published: January 2025

Background and objectives: Despite years of research, there is still no definitive evidence of a link between the clinical manifestations of schizophrenia and atypical asymmetry, and a consistent model of association is lacking.

Methods: We examined 70 men diagnosed with schizophrenia according to the criteria of ICD-10 and DSM-IV, using the "Brief Psychiatric Rating Scale" (BPRS).

Results: Our analysis revealed several statistically significant correlations between the coefficient of right-hand dominance and symptoms from the BPRS.

Conclusion: Positive symptoms are associated with right-handedness and more severe exacerbations of the illness, while affective symptoms in non-right-handed patients may be associated with a more favorable course.

Composite cement is a binder system containing a mineral component that improves the construction and technical properties of cement. During separate and combined grinding of composite cement components in a high-energy centrifugal impact mill the mechanical activation of the mineral additive is carried out and mechanocomposites are formed, affecting the hardening and properties of the finished product. Hydration schemes for composite cements of separate and combined grinding are proposed. It is shown that during the hydration of composite cements, X-ray amorphous calcium hydrosilicates and hydroaluminates are formed, which crystallize under nonequilibrium conditions according to the non-classical kvataron mechanism. This leads to the formation of a fractal structure of cement stone with high early strength.
Conceptual aspects of designing mineral powder compositions from raw materials of natural and technogenic origin
Authors: Frolova M. A.
Published: January 2025

Research related to the development of the criteria for optimizing the composition of building mixtures based on mineral powders is currently still relevant and is one of the priority issues in the industry. Based on the fact that the processes of disintegration of raw material of rocks are predominantly used in preparation for its further technological processing, this paper proposes to use the parameter of the surface activity of the resulting powder system to assess the process of mechanical activation during material crushing, and to use the analog value of the Hamaker constant to optimize the composition of the mixture based on the principles of maximum dispersion interaction of powder particles. Using the example of rocks of various genetic groups of natural and technogenic origin (basalt, quartz and polymineral silica-containing sands, saponite-containing waste from the enrichment process of kimberlite ores), the algorithm for calculating the above-mentioned characteristics is shown. It has been established that with the same duration of grinding (and comparable values of the dimensional characteristics of the resulting powders), the surface activity increases in the following series: polymineral sand, quartz sand, saponite-containing material. The dispersion obtained by mechanical grinding of serpentine is characterized by the maximum dispersion interaction of the particles of the studied mineral powders (basalt, saponite-containing waste, serpentine), estimated by the values of the analog Hamaker constant.

The multicomponent composition of the raw material mixture and the heterogeneity of the structure of highly functional concretes at various scale levels make it possible to effectively control the formation of indicators of its damping properties due to prescription and technological factors. Experimental compositions included Portland cement, quartz sand, granite screening, silica, metacaolin, quartz flour, microcalcite, shrinkage compensators, hyperplasticizer and reinforcing microfiber. The hydrodynamic properties were investigated by methods of free and forced oscillations.Experimental compositions included Portland cement, quartz sand, granite screening, silica, metacaolin, quartz flour, microcalcite, shrinkage compensators, hyperplasticizer and reinforcing microfiber.

The hydrodynamic properties were investigated by methods of free and forced oscillations.A laboratory complex of vibrodynamic tests has been developed that provides automated processing of the amplitudes of bending damping vibrations of the first mode of concrete samples to calculate the dynamic modulus of elasticity and the logarithmic decrement of attenuation. The high accuracy of the results obtained made it possible to identify the nature of the influence of various prescription factors (consumption of cement, pozzolan additives, microfiber, shrinkage compensators) on the dynamic modulus of elasticity and damping of concrete. An increase in the value of concrete damping (by 1.22 times) was established with an increase in cement consumption from 300 to 734 kg/m3. The introduction of shrinkage compensators, differing in the mechanism of action, made it possible to obtain non-shrinkable injection molding compositions and favorably affects the vibrodynamic parameters correlating with the magnitude of the overall heterogeneity of the microstructure of concrete.The results of the research have been tested in the manufacture of prototypes of concrete and reinforced concrete cutting machines (small-sized milling machine), as well as laboratory testing equipment.

The article presents the results of an experimental substantiation of the production of plywood for construction purposes under conditions of low-temperature pressing and reduced binder consumption. Cost reduction while maintaining performance refers to the competitive advantages of the material. One of the ways to solve this problem is to significantly reduce the temperature of hot pressing plywood (below 100оC) and reduce resin consumption (less than 100 g/m2). The study implemented a second-order B-plan and developed regression models of the dependencies of the mechanical parameters of plywood on the pressing temperature, resin consumption and the proportion of additive modifiers – aluminum chloride and magnesium chloride. The decrease in the strength when splitting plywood on an unmodified phenol-formaldehyde binder is due to the low degree of polycondensation of the binder during low-temperature pressing. Rational values of the factors of the plywood production process were obtained by analyzing regression mathematical models of the dependence of plywood indicators on variable factors. For plywood based on a modified binder, the results were obtained – the strength of the samples when rolling over the adhesive layer after boiling was 0.808 MPa at the following modes: pressing temperature 95оC, resin consumption 93 g/m2 and modifier consumption 0.5% by weight of the resin for samples with the addition of magnesium chloride. The results obtained can be recommended for use in the production of plywood for formwork with the required mechanical properties.
Development of a composition of a complex swelling additive for the production of expanded clay
Authors: Chumachenko N. G.
Published: January 2025

A standard assessment of clayey raw materials from the Neftegorsk field in the Samara region was carried out. It has been established that clay, in all respects except CaO content, meets the GOST requirements for raw materials for the production of expanded clay gravel. The group of clay raw materials is defined as slightly intumescent clay. The influence of firing temperature, content of organic and iron-containing additives on the degree of swelling was studied. A non-standard assessment of clay was carried out using a calculation method based on chemical composition. The types of necessary additives and their percentage content for targeted adjustment of the composition in order to obtain maximum swelling are theoretically justified. A complex additive composition has been developed to increase the swelling properties of clayey raw materials from the Neftegorsk field, including flask, pyrite cinders, alkaline aluminum etching sludge and solar oil.

Published: January 2025

This study aims to examine the impact of the Quizizz application on vocabulary mastery as part of English learning exercises among tenth-grade students at SMK Negeri 2 Panyabungan, focusing on recount text topics. It addresses challenges such as limited vocabulary mastery, low motivation and interest in learning English, and insufficient opportunities for practice. A quantitative approach with a quasi-experimental design was employed, involving experimental and control classes. Data collection included pre-tests, treatments, and post-tests using 20 multiple-choice questions on recount texts. The findings revealed that the experimental class, which used Quizizz, had a higher average post-test score (82) compared to the control class (67.5). Data analysis using the t-test showed a t-count of 4.965 and a sig. tailed (p) score of 0.001, with α = 0.05 and degrees of freedom (df) = 19. Since p < α (0.001 < 0.05), the alternative hypothesis was accepted, and the null hypothesis was rejected. These results indicate that using the Quizizz application significantly enhances students’ vocabulary mastery compared to traditional teaching methods. The study highlights the effectiveness of Quizizz in addressing vocabulary and engagement issues in English learning.

Poor food safety in school children’s snacks (SCSS), characterized by the presence of hazardous additives like borax, formalin, and rhodamine B, poses significant risks to children's health, potentially leading to long-term health issues and developmental problems. This research aims to identify the presence of these dangerous substances in SCSS and determine which types of snacks pose the highest food safety risks. The study employed a simple random sampling method to collect popular snack samples frequently consumed by students in various areas of Jayapura. Qualitative testing for borax, formalin, and rhodamine B was carried out using test kits. The results revealed that several SCSS samples contained these harmful substances, with notable variability across different regions. The analysis identified specific types of snacks—such as meatballs, noodles, colorful beverages, and snacks—that failed to meet the expected food safety standards. The study concludes that hazardous food additives are still being used in the production and sale of SCSS in Jayapura City, posing significant health risks to children. Enhanced regulation and awareness initiatives are necessary to improve food safety in the region. Public health authorities are encouraged to implement stricter monitoring and provide targeted education to both vendors and consumers to reduce the prevalence of these unsafe practices.

Published: January 2025

Plants and organic foods inherently contain bioactive compounds that combat oxidative stress effectively. A pharmacological overview of the activity and action of the active compounds against X-ray damage is provided, along with a review of the chemistry, functionality, and application aspects of active compounds derived from natural sources that may mitigate the harmful effects of X-ray radiation and shield biological systems from oxidative stress. The findings revealed that natural antioxidants such as natural compounds (lactoferrin, curcumin, melatonin, phycocyanin, and saponin) and phenolic compounds in plant extracts could be preventive and therapeutic agents against X-ray-induced toxicity. Natural antioxidants function as radiation protectants, mitigating oxidative stress induced by X-ray exposure. Given the non-toxic nature of the active compounds examined in this study, we suggest using them to produce a nutraceutical beverage that can be consumed or included in a daily diet to minimize oxidative stress.

Systemische Wirkungen des Internationalen Jugendaustauschs – Zwischenbilanz zur Forschungslage
Authors: Becker Helle
Published: January 2025

Helle Becker stellt im ersten Beitrag die Forschungslage zu diesem Praxisfeld dar. Sie zeigt, dass Internationale Jugendarbeit seit dem Ende des Zweiten Weltkriegs als politischer Hoffnungsträger insbesondere für die Völkerverständigung gilt. Gerade gegenwärtig ist die Erwartung plausibel, die politischen Dimensionen Internationaler Jugendarbeit vor allem für politische Bildungsprozesse zu nutzen. Die Autorin stellt Überlegungen dazu an, wie Wirkungen internationaler pädagogischer Maßnahmen überhaupt erforscht werden können und was unter systemischen Effekten Internationaler Jugendarbeit verstanden werden kann. Nach diesen Vorüberlegungen untersucht sie vorliegende Studien zu systemischen Effekten des Praxisfeldes. Sie zieht das Fazit, dass bisher kaum politische Folgen oder strukturelle Veränderungen nachgewiesen worden seien, wohl aber individuelle Verhaltensänderungen. Aus diesem Befund leitet sie abschließend Desiderate für die Forschung ab. Vor allem müsse es um den Zusammenhang von individuellen und systemischen Effekten gehen, so Becker.

In der Migrationsforschung der Sozialen Arbeit ist die Bestimmung von Migration als Forschungsgegenstand im Unterschied zu anderen Disziplinen, insbesondere im Vergleich zur Erziehungswissenschaft und zur Soziologie, bislang noch kaum ausreichend theoretisch und empirisch bestimmt worden. Der vorliegende Beitrag setzt sich mit diesem Defizit auseinander und schlägt eine marginalisierungstheoretische Verortung der Migrationsforschung in der Sozialen Arbeit vor. Diese wird ergänzt und weiter konkretisiert durch den differenztheoretisch ausgerichteten Intersektionalitäts-Ansatz und verknüpft mit dem handlungstheoretischen Ansatz von multicultural-conviviality. Als zentrale Handlungsfelder für die Migrationsforschung in der Sozialen Arbeit werden Familie, Arbeit, Zivilgesellschaft und (Sozial-)Staat vorgeschlagen, in denen auf zentrale soziale Dimensionen – Care, Inklusion, Gesundheit, und Nachhaltigkeit – fokussiert wird. Methodologisch ergeben sich aus dieser Gegenstandsbestimmung neue Herausforderungen, die erkenntnistheoretisch unter Einbezug figurations- und prozesstheoretischer Ansätze, sowie unter Berücksichtigung des Fallstudienansatzes weiterbearbeitet werden können. Auf dieser Grundlage können Bedeutung und Wirksamkeit von professionellem und organisationalem Handeln in Migrationskontexten besser analysiert werden. Dies könnte einen wichtigen Beitrag zur Weiterentwicklung der Sozialen Arbeit im Migrationskontext leisten.

Welchen Beitrag leisten Schulbücher bei der (Re-)Produktion rassifizierter Differenzverhältnisse, und welchen Effekt haben sie auf Subjektbildungsprozesse der Schüler*innen? Im Rahmen des Artikels wird eine bisher recht unterbelichtete Perspektive auf Schulbücher und Unterrichtsarbeit im Anschluss an rassismuskritische und subjektivierungstheoretische Ansätze am Beispiel aus einer Dissertationsarbeit vorgestellt. Entlang der Untersuchung eines empirischen Beispiels wird ein Einblick in die sozialtheoretischen und methodologischen Ansätze der Arbeit gegeben.
Beheimatung nach der Flucht: Erkenntnisse auf der Grundlage der Resonanztheorie
Authors: Pietrzik Karoline
Published: January 2025

Das Beheimatungskonzept dieser Studie orientiert sich an der Tatsache, dass die Welt im Wandel und in Bewegung ist und an der Akzeptanz, diese Situation so anzunehmen und Heimat im Sinne von Beheimatung entsprechend zu konstruieren. Die Wirkungsprozesse der Fluchtbewegung erfordern eine realitätsbezogene Auseinandersetzung mit Beheimatung. Dabei ist es notwendig, Menschsein in den Mittelpunkt zu stellen. Die vorliegende Studie widmet sich deshalb der Frage, wie eine gelingende Weltbeziehung unter Bedingungen der Flucht möglich ist. Dabei wird anhand eines narrativen Interviews mit einer geflüchteten Frau in Anlehnung an die Resonanztheorie des Soziologen Hartmut Rosa untersucht, wie Resonanzbeziehungen entstehen können und wie sich dabei das Resonanzverhältnis zur Welt auf den Prozess der Beheimatung auswirkt.

Direct and face-to-face contact in the provision of services and consultations provides a great opportunity for corrupt practices. Therefore, efforts are needed to minimize or even eliminate face-to-face practices directly by utilizing information and communication technology (ICT) in the electronic-government framework for service delivery and consultation, so that direct contact between service providers and service users no longer occurs. In Indonesia, the opportunity for that already exists with the issuance of Presidential Instruction No. 3 of 2003 concerning on National Policy and Development of Electronic-Government Strategy, with the aim of supporting effective and efficient governance changes, facilitating communication between central and regional governments, control transparency in governance and ensuring the implementation of governance principles that wellÂ Keywords: Public Services, Electronic-government,Â effective and efficient

AbstractÂ The geographical condition of the territory of the Republic of Indonesia as an archipelago which has 2/3 of the area in the form of waters has given birth to the Archipelago's Insight as the view of the Indonesian people based on Pancasila and the 1945 Constitution regarding themselves and their environment in the form of life as a political, economic, socio-cultural and defense unit within one space of life. This archipelago insight will always animate the Indonesian people in national life and life as well as in the international life of the Indonesian people. The implication of the island nation is that the Indonesian people must realize that their lives and future depend on the ocean and make the best use of the sea and make it as the main capital of development.Keywords:Â Nusantara Insight, Main Capital of DevelopmentÂ
Pengurangan Resiko Bencana Alam Melalui Pengembangan Kompetensi Aparatur Sipil Negara Badan Penangulangan Bencana Daerah di Jawa Tengah
Authors: Sudaryanto Sudaryanto
Published: January 2025

Wilayah Indonesia terletak di daerah ring of fire dan megatrust sehingga rentan bencana alam, termasuk wilayah Jawa Tengah yang juga dikenal sebagaiÂ  supermarket bencana. Kejadian bencana alam terus secara grafis menunjuk trend yang terus meningkat. Penelitian dengan metode kualitatif telah dilaksanakan dengan hasil, pengurangan resiko bencana alam melalui Pengembangan Kompetensi ASN BPBD di Jawa Tengah, tidak dapat dirumuskan. Hal tersebut dikarenakan bahwa pemasalahan bencana adalah juga masalah publik dan seharusnya dapat diselesaikan dengan ditetapkannya suatu kebijakan publik sebagai kerangka hukum dan administrasi. Namun berdasarkan data dan informasi dari informan ternyata Pemerintah Kabupaten dan Kota belum menetapkan kebijakan dimaksud. Maka akibatnya ASN BPBD belum memiliki kompetensi pengurangan resiko bencana alam dan dampaknya seperti yang diharapkan.Kata Kunci: Kebijakan Bencana;Risiko;Kompetensi.
