Ecosystem Services of Hospital Gardens - Based on Microclimate Analyses of Green and Blue Garden Elements
Authors: Takácsné Zajacz Vera , Szilágyi Kinga M
Published: July 2021

The increasing urbanization process of the last decades has resulted in negative impacts and changes in the quality of the urban environment, as reflected in mortality and morbidity data (Páldy, 2018). The quality of the environment, the urban climate, the increased frequency and duration of extreme weather events, ultimately threaten human well-being. To design and build liveable cities, the quality of the urban environment must be improved, and improving micro- or local climate is an important factor in this. Increasing the proportion and quality of biologically active surfaces, i.e. the ecosystem services provided by green spaces, is one of the most effective tools for urban conditioning and enhancing human well-being. Determining the proportions of the green area, the design of vegetation, the choice of pavements and microarchitectures all determine the microclimate of an open-space. This has been confirmed by a large body of research and implemented work, but it is also important for designers to make a preliminary prediction of the impact of any intervention on the climatic conditions of the design site. These predictions will help cost-effective designing to determine which intervention will result in climate change.

This research uses two specific examples to examine the effectiveness of each landscape designing tool and to show which designing tool produces what and how much climatic impact. For these studies, we used a climate modeling program (ENVI-MET), which runs simulations to infer the climate modifying effects of landscape planning tools.

In the course of the research, we have shown that the local climate of hospital gardens could be significantly influenced by favorable, environmental-friend paving, a higher green cover ratio, and a well-developed and sufficiently dense tree canopy, and various water features.
Substituting Ti-64 with Aa2099 as Material of a Commercial Aircraft Pylon
Authors: Khalid Hamza , Gomez-Gallegos A.A.
Published: July 2021

The aircraft industry is striving to reduce the weight of aircraft to save fuel and hence reduce total cost. New alloys and composites with properties such as low weight and high strength are continuously developed. Titanium alloys have the best strength-to-weight ratio among metals which makes them very suitable for aircraft applications. Ti-64 is the most common Titanium alloy used in aircraft. AA2099 is a 3rd generation Al-Li alloy and has the lowest density among all Aluminium alloys making it very attractive for aircraft applications. Pylons of commercial aircraft are currently made primarily with Ti-64 and this study focused on the replacement of Ti-64 with AA2099. Loading conditions, operating temperature, corrosion resistance, manufacturability and recyclability of the pylon were analysed of both Ti-64 and AA2099. Three critical scenarios were chosen for the loading conditions of the pylon. These were simulated using finite element analysis first using Ti-64 and then AA2099. From the results, it is evident that using AA2099 as the material of the pylon instead of Ti-64 offered weight savings. The operating temperature, manufacturability and recyclability also showed advantages when using AA2099 whereas corrosion factors favoured Ti-64, since AA2099 was found to be very prone to galvanic corrosion.
Tracking Land Use Land Cover changes from 2000 to 2018 in a local area of East Java Province, Indonesia
Authors: Indarto Indarto , Hakim Farid Lukman
Published: July 2021

Land Use Land Cover (LULC) changes represent human influences on the natural ecosystem. This study aims to analyse such changes in the eastern part of East Java, a region of ± 3320.3 km2. The changes are analysed by comparing two editions of maps (the National Digital Map and Landsat-8). Five subsets are explored to understand the LULC changes caused by the development of: transportation infrastructure; industrial sites; the agricultural sector; tourism; urbanisation; and sub-urbanisation. Regional development from 2000 to 2018 has increased built-up areas by 40.55% (122.5 km2), while paddy fields have increased by 71.08%, and forest plantation areas by 16.03%. Conversely, the development has reduced rural areas by 61.06% (860.1 km2) and water bodies by 54.02% (44.52 km2). The LULC has significantly changed the natural landscape to a human-dominated landscape, which is potentially fragile in the face of the disasters to which the region is prone.

Authors: Blagoev Ivaylo , Vassileva Gergana , Monov Vladimir
Published: July 2021

The presented work examines the existing approaches to providing e-Learning content based on learners’ prior knowledge. An analysis of the existing tools for the development of e-Learning content is performed and their suitability for creating personalized learning content, reflecting the previous competencies of the learners, is carried out. In the paper we have used a step-by-step process of creating and providing personalized knowledge. For data analysis, an approach of describing small structural units of knowledge through competencies is used. As a result of our study we have proposed a conceptual model including interactive resources for analysis of the accumulated prior knowledge and tools for providing personalized content to the learners. Perspective directions for future work are also outlined.
An IRGA-MACS Based Cluster-Head Selection Protocol for Wireless Sensor Networks
Authors: Inam Muhammad , Zhuo Li , Ahmad Masood , Zardari Zulfiar Ali
Published: July 2021

In a volatile environment, a substantial number of sensor nodes are extensively dispatched to track and detect changes in physical environment. Although sensor nodes have limited energy resources, so energy-efficient routing is a major concern in Wireless Sensor Networks (WSN) to extend the network’s lifespan. Recent research shows that less throughput, increased delay, and high execution time have been provided with high energy usage. A new mechanism called the IRGA-MACS is proposed to overcome these inherent problems. Firstly, the Improved Resampling Genetic Algorithm (IRGA) is used for the best Cluster Head (CH) selection. Secondly, to assess the shortest path among CHs and nodes, the Modified Ant Colony Optimization based Simulated Annealing (MACS) has been speculated to minimize the time consumption during the transmission. The results show that the proposed approaches attain the supreme goal of increasing the network lifetime compared to existing methods.
Parameters of radish phytomass (Raphanus sativus L.) determined by vermicompost and earthworms (Eisenia fetida)
Authors: Kováčik Peter , Olšovská Katarína , Smoleń Sylwester , Ledwożyw-Smoleń Iwona
Published: July 2021

In 2-year outdoor pots experiment, which was realised in the vegetation cage situated in the campus of Slovak University of Agriculture in Nitra, both the impact of different doses of vermicompost (Vc) (0%, 10%, 20%, 25% and 50%) and the number of earthworms (EW) (0, 10 and 20 individuals/pot) in the soil substrate were studied on the quantitative and qualitative parameters of radish yield. The achieved results show that along with the increasing quantity of Vc, the total chlorophyll content also increased proportionally. The content of vitamin C declined and the content of nitrates increased in both the aboveground and underground biomass. The weight of the roots and leaves of radish increased until the content of Vc in the substrate did not exceed 20%. Vermicompost abundance >20% led to the decline of root and leaf biomass formation. The root yield and leaf biomass were higher in the presence of 50% Vc content in the substrate, compared with the control. The EW had mostly a negative impact on radish phytomass formation, particularly both weight and root diameter. The highest percentage of roots weight decline cultivated in the treatment with EW were obtained with the least dose of Vc (10%), thereby the least quantity of fodder for the EW. The impact of EW on the total chlorophyll, vitamin C and nitrates contents in roots and leaves was non-significant. The number of EW did not influence the root diameter and content of vitamin C; however, it affected the root weight.
Analysing (In)Justice in the Interplay of Urbanisation and Transport: The Case of Agrarian Extractivism in the Region of Urabá in Colombia
Authors: Toro López Maritza , Van den Broeck Pieter
Published: July 2021

Infrastructural design, transport and mobility policies are strong instruments for interpreting historical urban and regional transformation processes. The paper addresses the intercausalities between both of them. To do so, it briefly sketches debates on the causalities of transport infrastructure and urbanisation and the theory of technological politics, drawing attention to the relationship between transport infrastructure and politics, and how infrastructures and their techno-political frames include means of power and authority. From there, the paper moves to the debate on the relationship between social justice and transport, showing how transport systems embody social processes and social (in)injustice. The history of agrarian extractivism in the region of Urabá in Colombia serves as a case study. The paper shows how existing transport networks of the region of Urabá have supported the expansion of agrarian extractivist industries and more specifically the production of transport (in)justice. It explores the development of the infrastructural network, transport systems and urbanisation of this region from the early 1900s onwards. Results show how the actual agrarian extractivist industries of the region are causing huge challenges related to the overlapping of transport scales, congestion and risks of accidents in urban areas, and how actual transport dynamics in the region are affecting urban development, generating a high segregation characterised by uneven distributions of public services and transport infrastructures. The paper reveals that the existing transport developments in the region of Urabá have no support for local development and are mainly thought for the efficiency of agrarian extractivist industries over local economic development. Agrarian extractivism has been a consistent factor in the economic, political and social spheres, and since colonial times the appropriation of natural resources and the dispossession of territories has been omnipresent. This paper explores the historical role of transport in agrarian extractivism, the long-term impact of the prolongation of old mechanisms, and the interrelations of the latter with current urbanisation and development. It concludes that infrastructural developments in this region have supported agrarian extractivist industries, first in colonial times, but also more recently, showing the deep embeddedness of the relation between mobility and urbanity in the (agrarian extractivist) development history of this region.

Published: July 2021

The instructors of the undergraduate cornerstone design course in Mechanical and Industrial Engineering at Ryerson University aim to integrate diversity and inclusion into students’ design education.  Our goal is to provide resources that students can use to understand human capabilities and limitations, so their designs are better suited to a wide range of users. The project was broken down in four phases: Phase 1 consisted of scoping deliverables and background research; Phase 2 included courseware development; Phase 3 employed the courseware into the Fall 2019 offering of our cornerstone design course; and Phase 4 reviewed and analysed student’s work to determine the efficacy of the courseware.  To initiate this effort, we focused on three Human Factors: vision, hearing, and strength. We created a process whereby students could assess these Factors quantitatively for specific interactions and use the assessments to justify specific functional requirements and constraints of theirown designs.

Published: July 2021

Mentoring in engineering outreach is being adopted more and more by university programs that aim toincrease diversity in their school. It is fair to say that mentoring can be a useful tool to do this, but not always.Mentor training can help improve program outcomes (attendance, engagement, retention). In this study, we look at one case of a virtual engineering outreach program, find the challenges, and make recommendations for mentor training modules that could address challenges.  In doing so, we believe that this sets a foundation for building training for many mentor-based virtual outreach programs in engineering.
ENGINEERING LEADERS RETAIN THEIR TECHNICAL IDENTITIES: LIVING THE SOCIOTECHNICAL DUALITY
Authors: Chan Andrea , Rottmann Cindy , Reeve Doug , Moore Emily , Maljkovic Milan , Macdonald- Roach Emily
Published: July 2021

In this qualitative study, we investigate the ways engineering leaders across different industry sectors conceive of their own professional identities, including those who work in less engineering-intensive sectors such as financial and public services. Our findings are consistent with previous research that rejects adichotomizing of engineering identity into distinct technical and social dimensions along technical and managerial career paths [4], [11]. Drawing directly from the experiences of 29 engineering leaders, our results suggest that engineers in management and leadership, even those outside of traditional engineering industry sectors, retain technical dimensions of their professional identities. By challenging the assumption that engineers must abandon their technical identities in order to embrace leadership work, findings of this study can demonstrate to students and early career engineers they need not resist leadership for fear of losing their engineering identities.

Authors: Jenkins Randi , Sheth Sahil , Nestor Breanne , Mazer Adrien
Published: July 2021

Purpose: To assess the impact of therapeutic dose versus prophylactic dose anticoagulation regimens on outcomes in mechanically ventilated patients with COVID-19.
Methods: We performed a retrospective cohort analysis of consecutive mechanically ventilated adult patients with COVID-19 admitted to the intensive care unit (ICU) and initiated on anticoagulation from February 1st to May 31st, 2020. The primary endpoint was 14-day mortality. Secondary endpoints included 30-day mortality, hospital length of stay (LOS), duration of mechanical ventilation, major bleeding, and new thromboembolic event.
Results: Of the 121 mechanically ventilated patients with COVID-19, 33 in the therapeutic-dose group and 34 patients in the prophylactic-dose group were included in the final analysis. The therapeutic-dose group had a decreased 14-day mortality compared to the prophylaxis dose group (9.1% vs 41.2%, p=0.004). In addition, 30-day mortality was also lower in the therapeutic anticoagulation group (24.2% vs. 52.9%, p=0.024). A longer hospital LOS (45.7 vs 26 days, p=0.003) and duration of mechanical ventilation (33.9 vs 13.3 days, p<0.001) were observed in patients on therapeutic anticoagulation in comparison to the prophylaxis dosing group. A higher rate of major bleeding was observed in patients who received therapeutic anticoagulation.  
Conclusion: In this analysis of mechanically ventilated COVID-19 patients in the ICU, therapeutic dose anticoagulation was associated with a significantly lower 14-day mortality, but increased bleeding.
Comparison of Drug Withdrawal Processes in the U.S. and Other Nations
Authors: Hinal Patel  , Wertheimer Albert , Ding Qian
Published: July 2021

Medications have been withdrawn from as early as the 1900’s in several countries due to a variety of reasons. Most drugs have been withdrawn due to safety, efficacy, manufacturing issues, or the toxicities they address. While safety and efficacy of each new drug is taken into account, so is the process of drug withdrawal. Worldwide each country has its own medical agency which have different approaches on drug discovery and method of removal from the market. This removal process is simpler in several nations while more prolonged in others. Nevertheless, we still don’t know an effective method of drug removal from the market and therefore that is the focus of this paper. 
 This paper explores the drug withdrawal process in several countries due to hepatic and cardiovascular toxicities using the WITHDRAWN database. It also summarizes and compares the drug removal processes in the U.S., Australia, UK, EU, and Canada. Consequently, there was no data or evidence that supported one country more favorable or rapid than the other. However, based on the results from drug withdrawal processes, it appeared the U.S., UK, and EU were most comparable. Meanwhile, Australia appeared to have the lengthiest process.

Aim. To synthesize 2-(4,6-di(pyrrolidin-1-yl)-1,3,5-triazin-2-yl)-N-(alkyl, aryl)hydrazine-1-carbothioamides and study their antiviral activity against yellow fever virus (YFV).
Results and discussion. The target 2-(4,6-di(pyrrolidin-1-yl)-1,3,5-triazin-2-yl)-N-(alkyl, aryl)hydrazine-1-carbothioamides were obtained in three-step format from cyanuric chloride in good to high yields. The carbothioamides synthesized were estimated to possess the antiviral activity against YFV. The results obtained indicate that most of the compounds studied show the inhibitory activity against YFV in concentrations ≤10 μg/mL. For the most active substances, EC90 was in the range of 0.06 – 2.2 μg/mL. Good effective concentration values were accompanied by low levels of cytotoxicity resulting in excellent selectivity index values. The data obtained also indicate that the presence of an alkyl substituent in ortho-position of the N-aryl fragment is crucial for an effective inhibition of YFV growth.
Experimental part. 2-(4,6-Di(pyrrolidin-1-yl)-1,3,5-triazin-2-yl)-N-(alkyl, aryl)hydrazine-1-carbothioamides were synthesized starting from cyanuric chloride in three steps by its successive interaction with two equivalents of pyrrolidine, hydrazine and a series of alkyl-/arylisothiocyanates. The antiviral and cytotoxic activities of the target carbothioamides were studied in the Southern Research Institute (SRI, Birmingham, Alabama) by the viral cytopathic effect reduction assay and the virus yield reduction assay.
Conclusions. 2-(4,6-Di(pyrrolidin-1-yl)-1,3,5-triazin-2-yl)-N-(alkyl, aryl)hydrazine-1-carbothioamides synthesized have been proven to be a promising class of compounds for treating such a severe viral disease as yellow fever.

Materials and methods. The sample observation, questionnaire, formal-logical methods, analogies and comparisons, the system analysis, the content analysis were used.
Results. According to the results of our studies, it has been found that the formation and development of the Ukrainian legislation in the field of social protection and social security can be divided into four stages; each of them has special characteristics and trends. The main approaches to regulating the social protection system and social security include the Soviet and European models.
Conclusions. Considering the development of the Ukrainian legislation in the field of social protection and social security and the analysis of modern reforms it can be argued that today Ukraine combines the latest foreign and personal approaches and on their basis reforms the social protection and social security system with the implementation of the European social protection standards. The analysis has shown that the future social policy of our state should be based on the principle of justice and protection of vulnerable groups, with the preference given to social benefits, the system of the targeted assistance, a new healthcare system and pension protection.
The analysis of state programs in providing the availability of medical and pharmaceutical care to the population during the years of independence of Ukraine
Authors: Nemchenko A. S. , Liadenko A. V.
Published: July 2021

Dissatisfaction of the population with the low availability of medical and pharmaceutical care, as well as significant expenses from the pockets of citizens for medical services and medicines in the absence of the state compulsory medical insurance, indicate the need for transformation of the healthcare system (HS) in Ukraine. The concept of availability implies not only a physical opportunity to receive a service, but also a financial guarantee that the service will be paid for by the state. A clear list and volume of medical services, as well as drugs paid for at the expense of the state budget are the guaranteed assistance to the patient, which he receives free of charge. In this regard, the urgent task of the competent authorities is to improve the methodological approaches to the formation of government programs and packages of medical services depending on the incidence rates, the needs of the population and the financial capabilities of the state; they require the analysis of the results of the implementation of these programs and substantiation of the necessary changes.
Aim. To analyze changes in methodological approaches regarding the formation of state programs related to medical and pharmaceutical care for the population and determine the main tasks for the availability of medical services and medicines.
Materials and methods. In the course of the study the regulatory legal acts and statistical data of the state budget for the period of independence of Ukraine, information from official sites, as well as methods of system analysis, such as systematization, generalization, statistical and analytical ones, were used.
Results. Based on the results of processing legislative documents in the form of regulatory legal acts and state budgets of Ukraine the main methodological changes having the impact on the availability of medical services and medicines for the population in the healthcare system (HS) were determined. The analysis and systematization of the data made it possible to form the main factors for improving the availability of medical services and medicines for the population and the efficiency of medical and pharmaceutical care. Further expansion of the “Affordable Medicines” program, monitoring of the current program of medical guarantees will allow assessing changes in health protection and identifying key tasks for the future.
Conclusions. The study conducted has made it possible to determine methodological changes in the availability of medical services and medicines for the population in state programs for the period of independence of Ukraine, as well as to form directions for further research using methods of assessing medical technologies.
The Role of Marine Security Agency (BAKAMLA) As Sea and Coast Guards in Indonesian Water Jurisdiction
Authors: Kurniaty Rika , Suryokumoro Herman , Widagdo Setyo
Published: July 2021

The Indonesian geographical condition as an archipelagic state with abundant natural resources has put maritime security into its central issue. Several challenges are facing Indonesia’s maritime coordination. National maritime agencies are still overlapping and duplicating based on various laws and regulations. As part of the Indonesian vision to be a ‘global maritime fulcrum,’ Indonesia’s government established the Marine Security Agency (BAKAMLA). BAKAMLA aims to shift the law enforcement paradigm from a multi-agency multi-task to a single-agency multi-task. The establishment of BAKAMLA is expected to create law enforcement’s effectiveness and efficiency in Indonesia’s water jurisdiction. This study is a type of normative juridical research using a statute approach and case study approach. This study reveals that the emerging of BAKAMLA, based on Law Number 32 of 2014 concerning Marine, grants broad authority to the maritime security agency. BAKAMLA has the power to direct instant pursue, dismiss, inspect, arrest, carry, and deliver the ship to the related authorized agency for further legal proceedings. BAKAMLA also has the authority to integrated security and safety information systems. The presence of BAKAMLA does not necessarily disregard or eliminate other institutions in the same task, but as a guard to stimulate to synergize further the security and safety of Indonesia’s territorial waters under a single command unit.

Various social phenomena are often expressed on the social media twitter to attract responses from the public around the user. One of the interesting public responses in communication studies is language style. The issue of sexual harassment and violence against women is a common topic which gets a lot of response from the public. This research aims to analyze the differences between women and man language on the response column from a thread of twitter social media that is about a woman who had encountered a pressure and sexual harassment by the doctor who carried out the rapid test of SARS-CoV-2 on Soekarno-Hatta International Airport. This research was using qualitative content analysis approach toward thread’s response column on the twitter. We have found that the language style of man and women on the thread were different. The language of women relatively unclear compare to the man. The sentences created by the women used a lot of question tag at the end, whereas a man relatively did not. Women also did reluctantly to cuss and abuse compare to man. Women were relatively involved in conversation related with heart while men relatively involved in report conversation. Responses or interruptions by women were not to control, challenge, or threaten, but to support or emphasize the conversation. Meanwhile, men used more instrumental talk, report information, solve problems, and solve problems through information exchange. We also found a similarity between women and man, which was a language of draw conclusion.

Análisis de la situación laboral de las alimentadoras en la caficultura de la zona central colombiana, a la luz de la teoría de Nancy Fraser
Authors: Arango-Giraldo Pablo Andrés
Published: July 2021

El presente artículo, recoge resultados de investigación sobre la situación laboral de las mujeres rurales “alimentadoras” en fincas cafeteras tecnificadas en la subregión Centro-sur de Caldas (Colombia). De igual forma, su objetivo es caracterizar esta labor bajo el enfoque de justicia social propuesto por Nancy Fraser relacionado con la mala distribución y el reconocimiento erróneo. La metodología utilizada en el estudio, es de enfoque cualitativo, y particularmente el método biográfico-narrativo; asimismo el análisis se realizó mediante herramientas de Teoría Fundamentada. Los resultados revelan que en la caficultura colombiana prevalecen condiciones de trabajo injustas asociadas al bajo reconocimiento de las labores realizadas en el ámbito doméstico (caso preparación de comidas), pobre o nula retribución económica, y ausencia de marco legal laboral acorde con la realidad de las mujeres rurales dedicadas a este oficio.
El desarrollo en el Trabajo Social de Colombia: un campo transversal, disperso y polivalente
Authors: Contreras-Santos Maira Judith
Published: July 2021

En Colombia, los paralelismos del Trabajo Social con la noción de desarrollo, desde sus inicios hasta hoy, son esenciales. Sin embargo, las pesquisas sobre sus acervos son limitadas. En este artículo se expone una síntesis de la investigación documental realizada para visibilizar los rasgos del desarrollo impresos por colegas, desde 1987, en la Revista Colombiana de Trabajo Social del Consejo Nacional para la Educación en Trabajo Social (Conets). Por lo tanto, se interpretan, de modo crítico-propositivo, conocimientos, actitudes, prácticas y perspectivas de nuestra (in)disciplina-profesión sobre aquel dominio en dicho canal de divulgación (inter)nacional.
Experiencias de transición a la vida adulta de jóvenes que migraron solos. Un estudio en Aragón (España)

La transición a la vida adulta de los menores extranjeros no-acompañados – y, por ende, el papel de los servicios sociales especializados en la atención a esa etapa tan importante para quienes recibirán el nombre de ex-MENAs en la jerga institucional– constituye una de las etapas menos atendidas por las investigaciones académicas. Este artículo trata de identificar los retos y dificultades que los servicios sociales especializados enfrentan en la atención a esas personas al finalizar su acogida como menores de edad. Presentaremos los resultados de un estudio exploratorio cualitativo cuyo trabajo de campo reveló una serie de dificultades que puede presentarse en tres categorías (institucionales, contextuales y legales). Todas ellas revelan la necesidad de dotar a los llamados “programas de emancipación” con una organización estable, estandarizada y adecuadamente dotada de recursos económicos y técnicos. En el plano metodológico, los enfoques basados en el tejido comunitario aparecen como referencia óptima. En tercer lugar, otra necesidad confirmada en el estudio es la definición de rutas de transición planificadas, con apoyos jurídicos (permiso de residencia) y sociales, oportunidades educativas y de empleo.

Authors: Ruiz José Raúl , Munévar-Vargas Sandro Leonardo
Published: July 2021

El artículo presenta los resultados de la investigación en torno a las relaciones entre academia y política pública en familia. Específicamente se trabajó con cuatro universidades del país, que desarrollan programas posgraduales en familia y que a su vez han aportado a las políticas públicas de familia, tanto a nivel local como nacional. Los objetivos del estudio se concretaron en comprender los múltiples vínculos, agentes y contextos en ambos campos, el de la investigación en el campo de familia y su conexión con las decisiones que se toman para el desarrollo de políticas públicas de familia. La metodología se decidió a partir de la tradición hermenéutica y se optó por grupos focales, entrevistas y amplias revisiones de documentos.
Los resultados conllevan a plantear los múltiples perfiles de maestras y maestros quienes investigan con familias, sus aportes y conexiones; asimismo se establece cómo la investigación aporta conocimiento al hacedor de política pública, siendo un elemento crucial y que respalda la toma de decisiones. Igualmente, se asumen aspectos compartidos tanto para quienes investigan, como para quienes diseñan y concretan políticas públicas, aspecto que suma para una de las conclusiones: la dinámica compartida entre academia y política pública.

ANALISIS PALEOSTRESS SISTEM SESAR BARIBIS - SEGMEN SESAR BREBES BERDASARKAN DATA SESAR SKALA SINGKAPAN
Authors: Adhitama Ramadhan

Gempabumi di Pulau Jawa Indonesia merupakan fenomena yang sudah dimaklumi terjadi, dikarenakan lokasi geografis yang berdekatan dengan jalur subduksi Asia Tenggara – Hindia Australia. Namun kontribusi struktur geologi bukan hanya berasal dari mega-thrust hasil dari subduksi saja, melainkan struktur sesar yang berada di Pulau Jawa juga menimbulkan beberapa event gempabumi yang signifikan dan bencana yang besar.Gempabumi dangkal (hiposenter gempa lebih dangkal dari 70 km) di Pulau Jawa sangat dipengaruhi dari struktur sesar di kerak bumi yang sesar tersebut dapat dilihat bahkan di permukaan bumi melalui DEM (digital elevation model) maupun skala singkapan. Sesar-sesar ini didominasi oleh sesar naik berupa sabuk lipatan dan sesar anjak (fold and thrust belt / FTB): Sesar Baribis dan Sesar Kendeng; juga sesar – sesar mendatar, seperti: Sesar Cimandiri dan Sesar Opak.Sesar Baribis seringkali digambarkan berupa sesar dengan arah strike barat timur, yang memanjang dari Jawa Barat hingga Jawa Timur. Interpretasi Sesar Baribis menjadi satu sesar besar yang meneruskan sesar tersebut hingga tersambung dengan back thrust yang ada di utara Pulau Lombok. Interpretasi seperti ini dirasa kurang tepat dalam penggambaran sesar detail, dikarenakan banyaknya partisi Sesar Baribis yang terlihat pada keadaan geologi permukaan. Serta dengan simplifikasi seperti ini akan menimbulkan analogi potensi gempa yang keliru dalam estimasi magnitudo gempabumi.Analisis Paleostress menggunakan data sesar skala singkapan (1~6 meter) dengan mengukur kedudukan dari sesar dengan arah kinematika yang diambil dari parameter pergerakan berupa slickenside maupun offset perlapisan yang diamati di lapangan. Kemudian data di analisis menggunakan metode sumbu kinematik (Marrett dan Allmendinger, 1990) lalu data diproses menggunakan peranti lunak Faultkin 8.07. Hasil analisis paleostress Segmen Brebes Sesar Baribis berdasarkan data sesar skala singkapan yaitu: sumbu P (s1) terfokus di arah Utara-Selatan mengikuti deformasi orthogonal subduksi Jawa, dan sumbu T (s3) memiliki 2 arah yaitu barat-timur akibat dari sistem sesar geser mengiri dengan jurus timurlaut-baratdaya, dan pada sumbu vertikal akibat dari sistem sesar naik Baribis.

Sumur eksplorasi LYS dan KYS merupakan dua sumur pertama yang dibor di Blok Bdg, daratan Sulawesi Barat oleh kontraktor Wilayah Kerja Eksplorasi. Beberapa analisis dan evaluasi geokimia dilakukan pada sampel sumur LYS dan KYS, yaitu analisis karbon organik total (TOC), rock eval pyrolysis (REP), reflektansi vitrinit (VR), jenis kerogen, kromatografi gas (GC), dan kromatografi gas/spektrometri massa (GC/MS). Untuk mengilustrasikan perbedaan dalam sejarah pembenaman dan kematangan thermal antara sumur LYS dan KYS, pemodelan sejarah pembenaman dan kematangan thermal telah dilakukan pada kedua sumur ini. Sumur LYS-1 merupakan sumur darat dangkal yang hanya melakukan penetrasi hingga Miosen Awal, yang secara thermal belum matang, sedangkan sumur KYS menembus hingga Eosen. Sedimen berumur Eosen diasumsikan matang lebih awal (sekitar 10Ma), karena adanya sedimen berumur Oligosen dan Miosen yang lebih tebal. Berdasarkan nilai TOC, VR, Tmax, profil kematangan, dan pemodelan sejarah pembenaman dan thermal dari sampel sumur LYS dan KYS, diasumsikan bahwa sampel sumur KYS lebih matang dibandingkan sampel sumur LYS.
