Remediation of the Landslide and Retaining Wall Sučević
Authors: Trbović Nikola , Kereš Boris
Published: December 2024

On the state road DC 1, section Gračac - Knin, instability appeared under the existing reinforced concrete retaining wall in the form of a translational landslide. The landslide covered an area with a width of 60-65 m, a length of 90-115 m, and the depth of the sliding surface is at an average depth of 6 m. In total, about 35,000 m3 of material was removed. As a result of the instability in question, the foundation of the existing reinforced concrete wall was undermined, which reduces the stability of the wall and the entire road above the wall.
The remediation of the landslide provided by the design includes the construction of a supporting structure made of reinforced earth with facing of concrete modular blocks. Stabilization of the existing retaining wall foresees the installation of geotechnical self-drilling anchors with a diameter of 38 mm and a length of 15 m.
The supporting structure is divided into six cascades, each of which consists of the mentioned system: concrete modular blocks, geogrids and embankment.
Displacements of the structure during construction were measured with inclinometers and the measurements were compared with the designed displacements.
Each level of the supporting structure has its own lining foundation with dimensions of 0.60×0.20 m, while the lowest level has a line foundation with dimensions of 0.80×0.40 m, under which there are micropiles with diameter of 180 mm and length of 6 m, at an axial distance of 2 m.
In this project, 11.375 pieces of concrete blocks were installed, whose total mass is 227,5 tons. In total, 4300 m3 of stone material with a granulation of 0-75 mm and 4300 m2 of geogrid were installed inside the reinforced earth structure.
A method of determining unsteady air permeability of rock
Authors: Togashi Yota , Osada Masahiko
Published: December 2024

For geological disposal of radioactive waste and large-scale collapse of rock slopes due to heavy rain fall, it is significantly important to determine the water transport in the rock mass including unsaturated zones. To precisely predict the two-phase flow of air and water in rock pore spaces, both the hydraulic conductivity and gas permeability must be accurately identified. Most existing methods estimate the air permeability from the differential pressure under steady-state conditions. There are still few methods for evaluating air permeability under unsteady state conditions. This study proposes a method of identifying the ever-changing permeability with time and pressure using a linearized governing equation for air permeability in porous media. This method is based on an exact solution of the linear diffusion equation and requires that air pressure be measured at three different coordinates to approximate the second-order partial derivative with respect to the coordinates. To validate the method, we compared the exact solution derived with the results of air permeability laboratory tests on granite and conglomerate in previous studies. After confirming that the exact solution well represented the results of previous experiments, the unsteady air permeability of the rock was estimated from the results of the same experiments using the proposed method. As a result, it was confirmed that not only can the air permeability be identified with the same accuracy as the steady-state method, but also the unsteady air permeability, which varies with pressure, can be identified.

Published: December 2024

The construction of a large dam implies a number of environmental changes and the accurate study of the rock mass foundation. Besides the aspects related to the foundation, the geologic and geotechnical characteristics of the reservoir area gained increasing importance due to the possibility of slope instability which might, eventually, affect the serviceability of the dam. Effects can be felt both upstream and downstream and therefore an accurate geological mapping is obligatory to understand and preview susceptibility to accidents.
Slope instability in rock masses is a complex phenomenon that can be manifested by different types of mechanisms often controlled by the geologic structure, namely the joints system. Changes in the existing stress state can lead to modifications in the slope morphology which tend to find a new equilibrium profile. The present work presents the geological mapping performed in the area covered by the reservoir of a large dam to be built on a rock mass composed of metasedimentary rocks. In order to assess the stability of the reservoir slopes, the geotechnical assessment included desk study and field survey, as well as the use of digital elevation modelling (DEM) in order to obtain a set of susceptibility factors maps. These included the geological map of the area, altimetry, slope angle maps, slope strikes and land use mapping complemented with stereographic projection of the joint system in different location for kinematic analysis. The combination of susceptibility factors led to the identification of areas where landslides can potentially occur based on weights of different susceptibility factors.

Published: December 2024

The architecture of the geological structure is very often an intricate composition of structural rock and soil masses, affected by divers and independently or simultaneously discontinuities syn, or post genetic, which sustain one or more local and regional aquifers, and is continuously submitted to gravitational, and seismically hazardous actions. Usually, all large infrastructure projects invariable pass through one or more complex areas in which objectives are affected by geohazards at various scales. This is also the case of the route of the highway Pitesti-Sibiu, Romania, which was investigated in several field campaigns to decrypt the complex geological and hydrogeological structure. Along 50km sections of the route, the highway steps over four large geologic structures (from South-Est to North -West): Getic Depression, Subcarpathian thrust belt, and Post-tectonic Cover of South Carpathians, and effectively cut up a stratigraphic column starting from Paleocene sandstones and claystone, up to Quaternary alluvial, deluvial or terrace deposits. All structures, which are situated less than 150 km from the Vrancea Seismic Zone, are affected by a few deep intra-Moesical faults and more recent and superficial thrust faults which turn into blocky fractured shapes in the upper deposits. Apart from the major seismic hazard which derives from the tectonic network of main and secondary faults and the vicinity with one of the strongest seismic epicentral areas of Europe, the expansive behavior of encountered soils, high terrain slopes, actual erosional processes along rivers and hydrogeological regime of regional aquifers sets as many additional traps of geohazards to highway route. The paper elaborates and details, one by one, all enounced geohazards, which were studied by diverse and numerous investigation methods: geological, geotechnical, hydrogeological, and geophysical, by a multidisciplinary team.
Parameters of overconsolidation of Jurassic clay soils in the Moscow region
Authors: Matveev Vladimir , Shanina Violetta
Published: December 2024

Jurassic clay deposits are distributed almost everywhere in the Moscow region. Clay soils are extremely sensitive systems to changes in geochemical and geophysical fields and therefore undergo profound changes during lithogenesis. Overconsolidation parameters characterize the initial stress-strain state of the rock mass. Jurassic deposits may be in the zone of influence of the designed structures, for the calculation of settlements of which nonlinear models of soil behavior are used. Due to the history of geological development of the Moscow region, which includes several glaciations, an important characteristic of clayey rocks is their degree of overconsolidation. As a result of the study, the behavior of these soils was studied and processed using various graphical methods. The samples were taken on the territory of Moscow (Fadeeva St. and Desenovskoe village) from a depth of 7.7 to 23.8 m and belong to the Oxfordian stage of the Jurassic system, being marine sediments. For the selected samples, the particle size distribution, chemical and mineral composition, and physical properties were determined. The mineral composition is dominated mainly by smectites (38.5-46.5%). In accordance with the classification according to GOST 25100-2020 according to the degree of salinity, the studied soils are distinguished from non-saline to slightly saline (0.40-0.71%), the type of salinity is marine. Based on the relative swelling strain without load, soils are classified from moderately swelling to highly swelling (10.6-38.9%). The soils under study are classified as heavy semi-solid clays (plasticity number 42-58%, fluidity index from 0.07-0.24 units). Overconsolidation coefficient OCR for Oxfordian clays at st. Fadeev ranged 2.1-8.1, which corresponds to overconsolidated and highly overconsolidated soils, and in Desenovskoye 1.2-1.9, that is, normally compacted soils according to the GOST 25100-2020 classification. The POP overconsolidation stress ranged 92-394 kPa and 175-1768 kPa, respectively. Thus, the data obtained indicate that historical stresses exceeded modern ones.

Published: December 2024

Tunnelling and Underground excavations in the Himalayan mountains is a formidable task, and the challenges were further amplified when the project was initially started by some other executing agency and after various technical and financial issues came to complete halt. After some years, these partially constructed projects are ageing and handed over to other agencies to complete it.
In case of Teesta VI HEP, the partially constructed project was handed to NHPC in 2019-20 i.e. after about 10 years to complete the balance works. After a decade of hiatus and the influence of worldwide epidemic situations like COVID 19 has made the work of completing the project much more challenging.
In this paper we will discuss in detail about the various challenges faced by engineering geologists from re-investigation to execution. Re-examination of information from a variety of sources like available progressive excavation data, additional topographical survey, geological / geophysical investigation, site specific vulnerable tunnel spans, surface mapping etc have been done to re-assess the geological conditions of surface and underground works. Accordingly, innovative underground investigation techniques, excavation methodologies, strengthening techniques of subsurface strata, support measures, tunnel re-alignment, cut slope design etc have been adopted that best suited the geological conditions. Along with this we will also discuss various cchallenges during re-sarting and re-stablishing the collapse faces and during crossing various perineal Nala and its feeder channels with low cover zone and adverse geology. We will also discuss various adopted solutions, remedial measures and mitigation plan to tackle these adverse geological problems during progressive tunnelling.
Application of geophysical investigations for detecting the groundwater springing in the Sirač limestone quarry, mining field Čelina

Published: December 2024

Rock materials, as a natural resource, are the most important mineral raw material used in construction. Limestone rocks are exploited in the Sirač quarry Čelina, which is then processed into two types of products: crushed stone and stone aggregates. In 2021, during the excavation process, a new feature of water accumulation appeared on the quarry plateau (208 m.a.s.l.) and water pools were formed, which tended to flow towards the northern part of the excavation plateau. In the same year, an exploratory well with a depth of 50 meters was drilled near the place where the water appeared. Artesian water came to the surface from the mentioned well, which confirmed the presence of groundwater. Given that the inflow of water did not decrease over time, research had to be carried out with the aim of solving the problem so that the quarry could be properly managed as a natural resource of building stone. In addition to geological prospecting, three different methods of geophysical investigation were applied at the end of 2023 to detect the source and extent of groundwater springing: electrical resistivity tomography (ERT), multichannel analysis of surface waves (MASW) and ground penetrating radar (GPR). A fault zone was detected by interpreting the research results, which probably represents a groundwater aquifer. It was determined that the layer cracks of the Triassic carbonate rocks in the deposit have low water permeability therefore the fault zone allows drainage of seepage and groundwater. In addition, impermeable grey-green Triassic clasts were registered in the sublayer, which probably represents a barrier to the percolation and movement of groundwater.
Towards a rapid and practical determination of the pin-rock interaction parameters of the CERCHAR abrasivity test
Authors: Kaspar Markus , Frühwirt Thomas , Latal Christine , Blümel Manfred
Published: December 2024

The CERCHAR test is a widely used index test for evaluating rock abrasiveness and associated tool wear in rock excavation. However, routine testing only assesses the wear on the pin itself. To evaluate the advancement rates in rock cutting during excavation, it is also crucial to consider the material removal of the rock. Recent studies have begun to include this aspect by developing advanced methods, automated testing devices, or using customized equipment for test evaluation. Yet, these methods are too time-consuming and specialized to be used in routine laboratory testing. This study investigates the correlation between traditional CAI and associated material removal by complementary measurements of the scratch groove on the rock specimen using a stereomicroscope. The presented approach enables the straight forward determination of additional parameters, such as rock volume removal and pin tip loss, based on the inherent pin tip geometry and associated scratch groove geometry. These parameters are then used to calculate the CERCHAR Abrasion Ratio, which serves as a proxy for the excavability of different rock types. Despite some minor limitations, this approach can deliver values that are comparable to those obtained using specialized equipment. Therefore, it has the potential to be a practical method for assessing abrasion and excavation on job sites.
Collapse of the Schieburg tunnel in Luxembourg: geological causes and emergency securing works
Authors: GRUSLIN Steve , HENNEBAUT Tiffany
Published: December 2024

On 27 August 2022, a collapse occurred in the Schieburg tunnel in Luxembourg (built in the 19th century) during repairs to the vault, following a particularly dry period. Around 400 m3 of debris flowed out in a matter of seconds, completely obstructing the tunnel and blocking the only railway line serving the north of Luxembourg towards Belgium. The rock slump occurred 60 m from the southern entrance, at a point where the overburden above the tunnel is 31 m, and under forest cover.
The geological and geotechnical studies carried out by our office included reconnaissance drilling with parameter recording to a depth of 80 m, geophysical prospecting using electrical and seismic tomography, and a structural study of all outcrops in the vicinity of the tunnel.
These investigations revealed a very complex geological and hydrogeological situation, with the collapse zone located at the intersection of a system of conjugate faults not recorded on the geological maps. Significant water infiltration was observed during the works, which complicated the stability of the excavation face and was a major cause of the weathering of the rock. The results obtained made it possible to estimate the volume and shape of the deconsolidated zone above the rock collapse and to propose safety measures to reinforce the deconsolidated zone above the tunnel, safely remove the pile of scree and repair the damaged vault. These safety measures were carried out using injections of the deconsolidated zone around the vault and anchors from the tunnel and the surface. The final support system consisted of metal T-beams and steel plates. Geotechnical monitoring of the securing works was carried out from start to finish, enabling the tunnel to be reopened less than one year after the collapse, despite very difficult access conditions both for exploratory drilling and for the works.
Development of the New Zealand landslides database
Authors: Christopher Roberts Ross
Published: December 2024

There have been over 1,500 recorded landslide-related fatalities in New Zealand (more than from earthquakes and tsunami combined) since 1760.
No single organisation in New Zealand has overall responsibility for landslides. As a result, landslide data has been stored in multiple discrete locations, often in widely varying formats, with no ability to compile the data to get an overall understanding of the distribution of landslide risk across the country. The New Zealand Landslides Database enables multiple organisations including the public to deposit factual information about every landslide into a single repository, and users to be able to access the data for their own purposes. Co-funded by the Earthquake Commission and Auckland Council, with support from GNS Science, the beta version of the database went live in 2022. By sharing this data organisations gain significant benefits by understanding how landslides might affect their people and assets.
This paper describes the development of the database and its use in a recent emergency event. It highlights the need for a consistent data schema to enable integration of multiple landslide inventories, describes the benefits, and proposes approaches to deliver the schema.

Published: December 2024

The area of Hrvatsko Zagorje (i.e. Croatian upland) is the most prone to landslides in the Republic of Croatia, with landslides occurring practically every day, caused either by natural or anthropogenic factors. Many of these landslides are activated along the network of state and local roads that pass through numerous cuttings mostly without any or with inadequate slope stabilization measures. Implementation of investigation works, design and rehabilitation works are all accompanied by numerous challenges. Designing effective landslide remediation measures requires a thorough understanding of geological, hydrological, and environmental factors influencing slope stability. This paper presents investigation works and rehabilitation design of a road landslide in Hrvatsko Zagorje in Croatia, where the landslide occurred downhill slope of the road.
Deformation forecasting and stability analysis of soft rock tunnel form Microsesmic source probabilistic localization
Authors: Sun Yuepeng , Xu Nuwen , Li Biao , Xiao Peiwei , Sun Zhiqiang
Published: December 2024

Surrounding rock deterioration and large deformation have always been a significant difficulty in designing and constructing tunnels in soft rock. The key lies in real-time perception and quantitative assessment of the damaged area around the tunnel. An in-situ microseismic (MS) monitoring system is established in the plateau soft tock tunnel. In this paper, the probability density field of MS source based on probability mapping is proposed, which lays a foundation for accurately revealing the progressive damage characteristics of soft rock tunnel. The spatial distribution of MS dissipative energy is established. The morphological evolution of tunnel with multiple damage degrees in axial and radial direction is analyzed. The results show that the probability density field of MS source restructured by probability density at the located source position can more accurately delineate the damage distribution of tunnel alignment. Based on the basics MS energy parameter，a three-dimensional model was created to visualize the damage zone of the tunnel surrounding rock. The model depicted varying degrees of damage, and three high damage zones were identified. The rapid increase of the depth and extent of high damage area can be used as the criterion of dynamic warning of large deformation of surrounding rock of tunnel. This paper provides valuable insights for damage and dynamic warning of surrounding rock of high-stress soft rock tunnel.
One unified hypothesis of neuropsychiatric disorders: Transdiagnostic common staging models
Authors: Wei Shyh-Yuh
Published: December 2024

Much like physicists perpetually seek a grand unified theory capable of making predictions for particles within the same theoretical framework, the idea that diverse clinical presentations of psychiatric disorders might be explained by common biological mechanisms is of interest to those in the field of biopsychiatry. Despite the attempts made by the Research Domain Criteria (RDoC) to develop a more physiologically oriented diagnostic concept, departing from phenotype-driven diagnostic systems such as the Diagnostic and Statistical Manual of Mental Disorders (DSM), the complexity of the RDoC matrix has made it challenging for those accustomed to conventional approaches. In this paper, I endeavor to integrate the diathesis-stress model, the allostatic load model, and the kindling model into what I term “transdiagnostic common staging models.” From this model, shared aspects among different traditional diagnostic categories become apparent, encompassing concepts such as excitatory-inhibitory imbalance, inflammation, inflexibility, and sensitization. While it is possible that different traditional categories may lean towards different neurocircuits or neurotransmitters, I also propose the potential for cross-system interactions. This approach may offer a promising avenue for understanding the complex interplay of biological mechanisms underlying psychiatric disorders, shedding light on their commonalities and differences.
The Role of International Cooperation in Indonesia’s Maritime Security: Study Case of MT Arman 114
Authors: Manullang Abel Josafat
Published: December 2024

Purpose: This study explores the critical role of Indonesia's maritime domain in national development, focusing on its function as a connector for its archipelagic geography and a repository of natural resources. It highlights biological resources, such as fisheries, and non-biological resources, including natural gas and oil reserves, while emphasising the importance of safeguarding and optimising these assets for sustainable growth.
Study Design/Methodology/Approach: The research utilises a qualitative approach, using secondary data from government reports, academic studies, and international maritime frameworks. A thematic analysis examines challenges and opportunities in Indonesia’s maritime security framework, with particular attention to non-state threats and the role of international cooperation.
Findings: Indonesia’s vast maritime territory, covering 6.4 million square kilometres, offers significant economic and environmental benefits. However, these benefits face threats from illegal, unreported, and unregulated (IUU) fishing, transnational crimes, and environmental degradation. Limited maritime security resources further hinder effective threat mitigation.
Originality/Value: This study highlights the need for a multilateral approach to maritime security challenges. Drawing on the case of the Iranian supertanker MT Arman 114, it underscores the importance of international cooperation and technological advancements in strengthening Indonesia’s maritime security.

Strengthening Non-military Defense to Strengthen the Unitary State of the Republic of Indonesia
Authors: Buana I Gusti Putu
Published: December 2024

Purpose: This study aims to explore effective strategies and measures necessary to strengthen non-military defence in Indonesia in response to increasingly complex non-military threats driven by technological advancements and globalisation.
Design/Methodology/Approach: The research adopts a qualitative approach with descriptive analysis to investigate inter-agency coordination, community participation, and technological integration as key elements of non-military defence strategy. Data were collected from various sources, including relevant legislation, academic studies, and real cases in Indonesia.
Findings: The analysis indicates that although Article 30(2) of the 1945 Constitution and Article 7(3) of Law No. 3 of 2002 emphasise the importance of participation by all national components, the implementation of non-military defence in Indonesia faces challenges due to unclear legal frameworks and insufficient inter-agency coordination. The 2023 cyber-attacks underscore the urgency for comprehensive regulation and effective coordination practices.
Originality/Value: This study contributes new insights by proposing a multidimensional approach to reinforce non-military defence through cross-agency collaboration, enhanced digital capacity, and community involvement, aiming to build a more responsive defence system
High Sensitivity Long Pulse Envelope Detector Assisted by Microwave Photonics
Authors: Paim Gonçalves André , Ivo Felipe S. , Coutinho Olympio L.
Published: December 2024

This article presents a concept of a long pulse envelope detector (ED) with a high sensitivity value based on Microwave Photonics (MWP). The process of envelope detecting of RF signals is achieved by the translation of the RF spectrum to the optical spectrum range followed by optical filtering to cut the lower sideband and the carrier, finally beating the remaining upper sideband into a low-speed photodetector (LSPD). The LSPD output signal is amplified by transimpedance gain. This approach depends only on the RF passing band of the phase modulator (PM) and the optical filter transfer function. This concept is experimentally demonstrated reaching envelope detector tangential signal sensitivity (TSS) values around to -40 dBm for RF input frequency range from 10 GHz to 20 GHz. The proposed architecture does not use any optical or video signal amplifier. The implementation of this approach is simple, employs few components, and Commercial off-the-Shelf (COTS).

Published: December 2024

A história da civilização humana, sua formação territorial e cultural, foi influenciada por constantes fluxos de imigração. Os processos migratórios impactam a vida de diversas pessoas em todos os continentes do globo terrestre, independentemente de gênero e idade. Muitos são os indivíduos que migram entre os diversos territórios, os quais são motivados por variáveis distintas. A migração é um fenômeno que também impacta a vida de milhares de crianças. A imigração infantil se constitui pelo deslocamento de crianças junto de suas famílias para um novo território, o que consequentemente marca e delimita essa infância. Dessa forma, surgem questionamentos acerca de como essas crianças percebem a construção de seu futuro diante da experiência marcada pela migração. Frente a esse contexto, o presente estudo teve como objetivo compreender a percepção de futuro de crianças imigrantes residentes no município de Cascavel. Para isso, realizou-se inicialmente uma revisão narrativa da literatura acerca da compreensão psicossocial dos fluxos imigratórios e da construção sócio-histórica da infância e os impactos no desenvolvimento infantil. Para a construção deste estudo, foi desenvolvida uma pesquisa qualitativa, na qual foi realizado um grupo focal, com a participação de crianças imigrantes residentes em Cascavel/PR. A pesquisa contou com a participação de duas crianças, de 6 e 10 anos. Os dados coletados foram interpretados a partir da análise temática de Minayo, o que possibilitou significar e se debruçar sobre a fala dos participantes, visando o esclarecimento das questões levantadas. Foram identificadas duas categorias temáticas: 1) A infância e as experiências da vulnerabilidade no país de origem; 2) Sentir-se pertencente e a construção de futuro para crianças imigrantes. Constatou-se que as crianças pesquisadas apresentam uma percepção de futuro neste novo território que habitam após o fluxo migratório. Elas sinalizam as fragilidades e inseguranças vividas em seus países de origem, mas sem romper definitivamente com suas historicidades, mostrando um olhar criativo acerca do amanhã. Além disso, a pesquisa permitiu identificar a importância da presença de políticas públicas que assegurem os direitos mínimos garantidos no ECA, que, além de ser um direito garantido a todas as crianças que habitam o território brasileiro, também é nos espaços institucionais, como a escola, que as crianças são impulsionadas a construir seu futuro. São as experiências nesses locais, especialmente o acolhimento vivenciado, que afetam e possibilitam que visualizem e se “enxerguem” em um futuro em construção.

Published: December 2024

COVID-19 is a respiratory disease caused by the coronavirus. The most common test technique used today for COVID-19 diagnosis is real-time reverse transcription-polymerase chain reaction (RT-PCR). However, compared to RT-PCR, radiological imaging such as X-rays and computer tomography (CT) may be a more precise, useful, and faster technology for COVID-19 classification. X-rays are more accessible because they are widely available in all hospitals in the world and are cheaper than CT scans, but the classification of COVID-19 using CT scan images is more sensitive than X-rays. Therefore, CT scan images can be used for the early detection of COVID-19 patients. One of them is using the deep learning method. In this study, a CNN algorithm with a VGG-16 architecture will be selected to classify COVID-19, intermediate, and non-COVID CT scan images using 2481 image datasets. First, pre-processing is done by resizing the image, converting the image channel into RGB, and dividing the dataset into a training dataset and a testing dataset. Then, the convolution process is continued by utilizing the pre-trained VGG-16 model from ImageNet. The results of testing the data with 97% accuracy were obtained. It is concluded that the model used to classify COVID-19, intermediate, and non-COVID CT scan images is effective and produces good results.
Comparative Seismic Evaluation of Building Codes: A Case Study on Structural Performance and Safety
Authors: Salim Jovan Thierry , Sidi Indra Djati
Published: December 2024

The evolution of structural design standards, from empirical approaches to modern precision, has significantly impacted seismic evaluation and building safety. Indonesia’s adoption of seismic standards in 2002, aligned with global practices like ASCE, introduced notable shifts in seismic design philosophy. This study offers a novel comparison of the seismic performance of a forty-story office building in Jakarta designed under SNI 1726:2002 versus the updated SNI 1726:2019. The unique focus of this research lies in evaluating how the shift from a uniform risk philosophy to a uniform hazard philosophy, alongside changes in earthquake return periods, affects structural safety and performance criteria. A comprehensive seismic evaluation was conducted using both nonlinear static (pushover) and nonlinear time-history analyses (NLTHA), with performance criteria based on ASCE 41-17’s Life Safety and Collapse Prevention levels. By employing both methods, this study uniquely highlights discrepancies between traditional pushover analysis and the more rigorous NLTHA, a comparison rarely explored in the context of Indonesia’s seismic standards. The results revealed significant disparities between the two methods. While pushover analysis exposes potential beam failure under the Collapse Prevention criteria, the NLTHA results suggest a more resilient behavior, indicating that the structure may perform better under real seismic events. These findings emphasize the limitations of pushover analysis and underscore the importance of more detailed nonlinear time-history analyses in accurately assessing the seismic performance of buildings.

Syntropic Environmental Education (SES) proposes new epistemological perspectives to understand the development of knowledge and interventions on environmental reality, based on the creation of dialogues between natural and human sciences through the concept of Syntropy. Based on these assumptions, this research identifies and analyzes the effects of the training process in EAS on the emotional, social and work competencies of teachers and their perceptions on the learning of students and the community. The data were analyzed in a qualitative-quantitative manner with a longitudinal design and show that 'work ability', 'understanding of the interrelationship between environment and health' and 'expansion of socio-environmental practical activities' were improved. Analytical and sustainability capacity are also found to be provided by supervision and pedagogical guidance. These results corroborate the importance of the training process in EE for the improvement of the teaching work and the perception of the existence and construction of more satisfactory social relationships.

Syed Taqi Abedi emerges as a significant contributor to the literary landscape. Despite his medical profession, Abedi’s passion for Urdu literature has been a constant thread throughout his life, originating from his student days. The Urdu literary realm is fortunate to have someone of Abedi’s caliber, who has consistently nurtured the growth of this rich tradition.
This abstract delves into Abedi’s profound admiration for Khawaja Altaf Hussain Hali, a prominent poet, and explores the depth of his connection to Hali’s works. Abedi meticulously examines Hali’s poetry, ghazals, criticism, and prose, displaying a deep affection for the diverse facets of Hali’s literary expressions. Hali, known for his moral, didactic, debate, and children’s poems, finds a dedicated analyst in Abedi.
While Hali’s association with the Aligarh movement and Syed Ahmad Khan is acknowledged, Abedi sheds light on another crucial influence — the mushairas organized by Anjuman Punjab. Only participating in four such gatherings, Hali presented poems like “Barkha Rut”, “Nishat-e-Umeed,” “Insaf,” and “Hub-e-Watan.” Abedi’s analytical lens dissects these poems, revealing the transformation in Hali’s thinking brought about by these mushairas. This abstract offers a comprehensive review titled “The Poems of Hali in the View of Taqi Abedi,” showcasing Abedi’s meticulous research and editing in presenting a nuanced perspective on Hali’s poetic legacy.

Fenomena bunuh diri merupakan realitas yang tak terelakkan dalam kehidupan masyarakat. Kasus-kasus bunuh diri telah terjadi di berbagai tempat, termasuk di Gereja Toraja Jemaat Ria Klasis Mengkendek. Tindakan ini memunculkan berbagai pandangan di kalangan masyarakat yang dipengaruhi oleh beragam latar belakang keyakinan dan pemahaman. Seseorang yang melakukan bunuh diri seringkali dinilai buruk atau bahkan dianggap melakukan dosa besar. Namun, pandangan semacam ini cenderung dangkal dan tidak memperhatikan faktor-faktor penyebab yang melatarbelakangi tindakan bunuh diri tersebut. Motif di balik bunuh diri dapat disebabkan oleh tekanan sosial yang dihadapi individu. Dalam penelitian ini, teori dekonstruksi Jacques Derrida digunakan untuk menganalisis dan mengurai faktor-faktor penyebab fenomena bunuh diri di Jemaat Ria Klasis Mengkendek. Penelitian ini bertujuan untuk mendekonstruksi faktor-faktor penyebab bunuh diri di jemaat tersebut melalui perspektif Derrida. Dengan menggunakan metode kualitatif, pendekatan historis, serta teknik pengumpulan data melalui wawancara dan observasi, ditemukan bahwa: pertama, faktor penyebab bunuh diri tidak semata-mata berkaitan dengan keimanan; kedua, masalah percintaan juga menjadi salah satu penyebab; ketiga, masalah ekonomi turut menjadi faktor penyebab; dan keempat, ketiga faktor tersebut dipengaruhi oleh kurangnya peran dan fungsi yang dijalankan oleh pemerintah, gereja, dan masyarakat. Faktor terbesar yang memicu tindakan bunuh diri di Jemaat Ria adalah kurangnya perhatian dari berbagai pihak, termasuk masyarakat, gereja, dan pemerintah.
