Authors: Hermiyanto M. H. , Ningrum N. Sudini
Published: March 2024

http://dx.doi.org/10.17014/ijog.vol4no3.20096Organic petrologic data of the DOM of Talangakar and Muaraenim Formations show that the organic matter consisting mainly of vitrinite group is essentially composed of telocollinite (1.0 – 70.8 %) and desmocollinite (0.8 – 66.6 %) with minor telinite (0.6 – 9.4 %), detrovitrinite (0.6 – 6.0 %), and cor- pocollinite (0.6 – 2.0 %). Minor exinite (0.4 – 7.8 %) and inertinite (0.4 – 8.0 %) are also determined. However, mineral matter varies from 0.6 – 99.44 %. Downwards, the increase in vitrinite reflectance (0.33 – 0.48 %) is concomitant with the depth of each formation. Furthermore, based on Rock-eval pyrolysis, TOC value of the Talangakar Formation ranges from 0.09 – 15.38 %, Gumai 0.34 – 0.39 %, Airbenakat 0.32 – 4.82 %, and Muaraenim between 0.08 – 15.22 %. Moreover the PY (Potential Yield) value variation of the Talangakar, Gumai, Airbenakat, and Muaraenim Formations are between 0.04 – 36.61 mg HC/g rock, 0.53 – 0.81 mg HC/g rock, 0.1 – 4.37 mg HC/g rock, and 0.07 – 129.8 mg HC/g rock respectively. Therefore, on the basis of those two parameters, the four formations are included into a gas - oil prone source rock potential. However, the Talangakar and Muaraenim Formations are poor to excellent category, whereas the Air Benakat tends to indicate a poor – fair category and Gumai Formation are only within a poor category. Tmax value of the Talangakar ranges from 237 – 4380 C, Gumai 316 – 3590 C, Airbenakat 398 – 4340 C with exceptions of 4970 C and 5180 C, and Muaraenim Forma- tions 264 – 4250 C. The Talangakar Formation contains kerogen Type II dan III, with the HI (Hydrogen Index) value varies from 45.16 – 365.43. However two samples show value of 0. The organic content of the Gumai and Air Benakat Formations are included into kerogen type III, with HI value ranges from11.87 – 40.82, and 19 – 114 respectively. Moreover the Muaraenim Formation has two category of kerogen type and HI value, those are type III with the HI value of 1 and kerogen type I with HI value of 821.29. The diagram of Tmax vs HI shows that the organic thermal maturation of the four formations are included into an immature to mature level.

DOI: 10.17014/ijog.v5i2.95Scientists, governments, employers, and communities have the same view on landslide disasters, that is the need to cut losses and to avoid loss of men. To deal with landslide disasters, an understanding of an area is required, especially for mitigation ( limitations and stabilization). To handle the slope - prone to landslides, an integrated approach is needed. A stabilization and integrated design (Starlet model) is a proposal in the handling landslide - prone slopes the integration among: (1) mapping system, (2) slope stability analysis, (3) simulation design of stable slope, and (4) guidance with environmental management along with monitoring. In addition, this also requires the participation of scientists, government officials, communities, and employers in facing these avalanche disasters. Citatah landslides formed a system with the largest to the smallest sizes that is a unity. The landslide in the western part of Pasir Pabeasan (Pasir Pabeasan - Citatah) is a complex one with the type of lateral spread. There are other landslides in the surrounding area, i.e: rock fall, rock toppling, slump, debris slide, and slide. The landslide shows the system and dimensions of landslide from the smallest to the largest one. Slopes in 22.29o to 44.28o should be noted because in general they are critical. They need stabilizations. Landslide area mapping system should consider the genetic region. A terrain genetic map will show areas of terrain genetic unit (TGU) which strongly supports the zoning maps of land movements. Based on terraingenetic unit (TGU), the Citatah landslides are common at symbol TGU 2331, 2232, locations between 2231 and 2331, locations between 2232 and 2331, and locations between 2233 and 2331, around the intersection of two faults (Cimandiri thrust fault cut by dextral strike - slip fault).
Indonesian Landforms and Plate Tectonics
Authors: Verstappen Herman Th.
Published: March 2024

DOI: 10.17014/ijog.v5i3.103The horizontal configuration and vertical dimension of the landforms occurring in the tectonically unstable parts of Indonesia were resulted in the first place from plate tectonics. Most of them date from the Quaternary and endogenous forces are ongoing. Three major plates – the northward moving Indo-Australian Plate, the south-eastward moving SE-Asian Plate and the westward moving Pacific Plate - meet at a plate triple-junction situated in the south of New Guinea’s Bird’s Head. The narrow North-Moluccan plate is interposed between the Asia and Pacific. It tapers out northward in the Philippine Mobile Belt and is gradually disappearing. The greatest relief amplitudes occur near the plate boundaries: deep ocean trenches are associated with subduction zones and mountain ranges with collision belts. The landforms of the more stable areas of the plates date back to a more remote past and, where emerged, have a more subdued relief that is in the first place related to the resistance of the rocks to humid tropical weathering Rising mountain ranges and emerging island arcs are subjected to rapid humid-tropical river erosions and mass movements. The erosion products accumulate in adjacent sedimentary basins where their increasing weight causes subsidence by gravity and isostatic compensations. Living and raised coral reefs, volcanoes, and fault scarps are important geomorphic indicators of active plate tectonics. Compartmental faults may strongly affect island arcs stretching perpendicular to the plate movement. This is the case on Java. Transcurrent faults and related pull-apart basins are a leading factor where plates meet at an angle, such as on Sumatra. The most complicated situation exists near the triple-junction and in the Moluccas. Modern research methods, such as GPS measurements of plate movements and absolute dating of volcanic outbursts and raised coral reefs are important tools. The mega-landforms resulting from the collision of India with the Asian continent, around 50.0 my. ago, and the final collision of Australia with the Pacific, about 5.0 my. ago, also had an important impact on geomorphologic processes and the natural environment of SE-Asia through changes of the monsoonal wind system in the region and of the oceanic thermo-haline circulation in eastern Indonesia between the Pacific and the Indian ocean. In addition the landforms of the region were, of course, affected by the Quaternary global climatic fluctuations and sea level changes.
Geothermal Prospect Selection Using Analytical Hierarchy Process (AHP): A Case Study in Sulawesi Island, Indonesia
Authors: Suryantini Suryantini , Wibowo H.
Published: March 2024

DOI: 10.17014/ijog.v5i4.107Analytical Hierarchy Process (AHP) is a Multi Criterion Decision Making (MCDM) Technique. It can handle any complex, multicriterion, and multiperson problems. In AHP, the problems are decomposed into a hierarchically structure and are given the weights according to its importance. Thus, the strength with which one alternative dominates another with respect to a given criterion can be identified. The output is a priority ranking indicating the overall preference for each decision alternative. This paper describes the application of AHP to select a geothermal prospect in Sulawesi Island to be developed in the near future. The alternatives consist of three geothermal prospects. i.e., Suwawa, Pulu, and Marana. Three major criteria are used and applied into those three prospects: Geoscience, Infrastructure, and Social-culture aspects. Under each of these major criteria, there are several subcriteria. Geoscience criterion which consists of Resources, Geothermal System, and Geological Risk Subcriteria is given the highest weight with the assumption that if resources are large and can be developed commercially, then there is no reason not to be exploited; the technology and other infrastructure aspects are no longer an obstacle. The result shows that Suwawa Prospect is the best option to be developed in the near future. The second option or rank is Marana Prospect, and the third is Pulu Prospect. This result is in agreement with the future plan of the development of Sulawesi Island. If the regulation and plan of development were suddenly changed, the goal of this AHP might not be appropriate anymore, and the second or third option might replace the first rank. The benefits of using AHP are (1) the facts and reasons behind the decision are well documented, (2) able to handle quantitative and qualitative inputs, (3) able to accommodate environmental, social and other influences, and (4) able to handle subjective judgments of individuals. Lessons learned from AHP application for geothermal prospect selection could be extended into multi criterion decision making at a group level.

DOI: 10.17014/ijog.v6i4.129The effusive eruption of Kelud Volcano in 2007 was different from the previous ones, which in general were more explosive. Among others, density and viscosity are factors that determine the type of eruption. Therefore, the study on the difference of the recent eruption style based on the density and viscosity of magma was carried out. The method used in this study was based on geochemical analysis of the rock and then a modeling was established by using the above parameter. The study on the explosive eruption was emphasized on the data of 1990 eruption, whereas the effusive eruption was based on the data of 2007 eruption. The result shows that the magma viscosity of Kelud Volcano depend on the H O concentration as one of the volatile compound in magma, and temperature which gives the exponential equation. The higher the increase of H O content the smaller the value of its viscosity as well as the higher the temperature. The H O content in silica fluid can break the polymer bond of the silica fluid, because a shorter polymer will produce a lower viscosity. The density of the silica content of Kelud Volcano ranges between andesitic and basaltic types, but andesite is more likely. The fluid density of the material of 1990 eruption is different from 2007 eruption. Compared to the 2007, the 1990 eruption material gave a lower density value in its silica fluid than that of the 2007 one. The low density value of the silica fluid of the 1990 eruption material was reflecting a more acid magma. The level of density value of silica fluid depends on its temperature. At the temperature of 1073 K the density of the 1990 Kelud magma is 2810 kg/m3 and the 2007 magma is 2818 kg/m3, whereas at a temperature of 1673 K, the density is 2672 kg/m3 and 2682 kg/m3 of the 1990 and 2007 eruptions respectively. A modeling by using an ideal gas law of Henry’s Law illustrated that the ascent of Kelud’s magma to the surface may cause changes in it’s physical properties. The evolution of the flow pressure in the conduit is characterized by three different areas; based of the conduit until the pressure is saturated, then at the level between release and fragmentation, and then the level above the fragmentation, that implicates the decrease in the wall friction.

Authors: Sutawidjaja Igan S. , Prambada O. , Siregar D. A.
Published: March 2024

DOI: 10.17014/ijog.v8i1.155Mount Sinabung, located in Karo Regency, North Sumatra Province, is a strato volcano having four active craters. Since its latest eruption about 1,200 year ago, a phreatic eruption occurred on August 27th, 2010. The eruption took place in Crater-I, which was initiated by a greyish white plume and then followed by black plumes as high as 2000 m above the crater. Altered rock fragments and ash were erupted during this event. The altered rocks show a development of argillic alterations which was formed in the hydrothermal system in depth. The alteration zone is formed along the northeast-southwest and northwest-southeast trend across the three craters. All of the craters are actively discharging solfataric gases, of which sulphur deposits are resulted, and they have been quarried by the local people. The age of the latest magmatic eruption was dated by 14C method from the charcoal sample found in the pyroclastic flow deposits near Bekerah Village.

Published: March 2024

DOI: 10.17014/ijog.v8i3.164The SE-NW trending Mountain Front of Central Sumatra Basin is located in the southern part of the basin. The Mountain Front is elongated parallel to the Bukit Barisan Mountain, extending from the Regencies of North Padang Lawas (Gunung Tua in the northwest), Rokan Hulu, Kampar, Kuantan Singingi, and Inderagiri Hulu Regency in the southeast. The Palaeogene sediments also represent potential exploration objectives in Central Sumatra Basin, especially in the mountain front area. Limited detailed Palaeogene sedimentology information cause difficulties in hydrocarbon exploration in this area. Latest age information and attractive sediment characters based on recent geological fieldwork (by chaining method) infer Palaeogene sediment potential of the area. The Palaeogene sedimentary rock of the mountain front is elongated from northwest to southeast. Thickness of the sedimentary unit varies between 240 - 900 m. Palynology samples collected recently indicate that the oldest sedimentary unit is Middle Eocene and the youngest one is Late Oligocene. This latest age information will certainly cause significant changes to the existing surface geological map of the mountain front area. Generally, the Palaeogene sediments of the mountain front area are syn-rift sediments. The lower part of the Palaeogene deposit consists of fluvial facies of alluvial fan and braided river facies sediments. The middle part consists of fluvial meandering facies, lacustrine delta facies, and turbidity lacustrine facies sediments. The upper part consists of fluvial braided facies and transitional marine facies sediments. Volcanism in the area is detected from the occurrence of volcanic material as lithic material and spotted bentonite layers in the middle part of the mountain front area. Late rifting phase is indicated by the presence of transitional marine facies in the upper part of the Palaeogene sediments.

DOI: 10.17014/ijog.v8i4.166A paleotsunami study having been conducted in 2011 took two study cases in Cilacap and Pangandaran coastal areas. These two regions have been devastated by tsunami in the past and had the most severe damaged on 17 July 2006. Trenching, beach profiling, and sediment sampling had been carried out, and further analysis at the laboratory had been done, such as grain size and fossil analyses and dating. In Cilacap, an iron sand layer was found as a key bed suspected as a paleotsunami deposits due to the content of anthropogenic fragments. In Pangandaran, two layers of tsunami deposit candidates were found having thickness of 5 - 6 cm at the top as a 2006 tsunami deposit candidate, and 5 - 10 cm at the bottom as a paleotsunami deposit candidate. Both grain size and fossil analysis results could explain that Pangandaran’s sediments are tsunami deposits while Cilacap’s ones are assumed to be deposited by another process rather than a tsunami.

Most countries consider dynamics of gross domestic product (GDP) as an indicator of economic policy success. Despite its importance and usefulness, GDP has limitations when it comes to assessing the situation in society and some economic development characteristics. The paper examines the relationship between gross regional product (GRP) per capita and the quality of life of the population in Russian regions. The impact of GRP on the quality of life was modelled on panel data using spatial fixed effects. As a result, well-specified models explaining differences in the dependent variable were identified. The study confirmed the presence of a constant elasticity of the integral index of the quality of life of the population in Russian regions for GRP per capita (0.588). Regional fixed effects were analysed in dynamics to assess their potential for ensuring the quality of life of the population. Additionally, opportunities resulting from GRP distribution and the effectiveness of regional policies in creating conditions for maintaining the quality of life were examined. Positive fixed effects increase in regions with high integral indices during the observation period, while the opposite is observed in lagging regions. Therefore, the inequality of regions is growing. The research demonstrated that previously created capacities for ensuring the quality of life of the population, not related to current GRP per capita, are a key factor. Consequently, the integral index of the quality of life in Russian regions is mainly determined not by current GRP per capita but by regional specificity and long-term regional policies of GRP distribution and ensuring the quality of life. In this regard, it is advisable to identify best practices of leading regions and disseminate them in order to support lagging regions.

A slowdown in economic growth implies the need to identify driver industries that will ensure the development on a new basis. The study aims to analyse industrial structural changes in the economy of the Udmurt Republic in the context of consolidated types of economic activity. It is suggested that shifts in the industrial structure of gross regional product (GRP) of the Udmurt Republic did not accelerate its economic growth. To achieve the set goal, theoretical aspects of structural changes were examined, a retrospective analysis of statistical data for 2004–2021 was performed. A modified methodology of dynamic macrostructural analysis was applied to study structural changes along with economic growth rate. Historical background of the industrial structure formation was analysed. When assessing the quality of structural changes, the index of physical volume of GRP per capita was used instead of GRP. Additionally, the study introduced the concept of “structural determinant of economic growth”. The conduced analysis revealed two structural lags and four small periods, characterised by a certain ratio of manufacturing and mining industries, in which five significant structural shifts occurred. The region’s industrial economic structure is the result of natural, geographical and political factors. Structural changes in the examined period, being a consequence of the volatility of world oil prices, did not ensure long-term economic growth or a fundamental transformation of the technological structure of the regional industry. The obtained results can be used to develop regional structural policies from the perspective of driver industries and ensure sustainable economic growth. Future studies should substantiate the “optimality” of regional economic structure, considering the interdependence of industries and integration into the national production system.
The Economic Nature and Essence of Regional Competitiveness: A Narrative Approach
Authors:   Lomonosov Moscow State University, Taranukha Y. V.
Published: March 2024

Regional competitiveness remains a debated issue. This problem requires a solution, as competitiveness is now seen not only as an indicator of achievement, but also as a tool for performance assessment of regional authorities. Additionally, a correct understanding of the essence of this phenomenon helps define objectives and tools of regional policy and management. The article aims to reveal the true nature of regional competitiveness as a form of competitiveness and describe its specific characteristics. The content analysis of relevant foreign and Russian publications shows that the stated problem cannot be solved by existing methods. Therefore, it is necessary to apply a fundamentally different approach that looks at the problem from the standpoint of struggle for economic benefits. A system-reproductive method of analysis demonstrated that, by its nature, competitiveness is the ability of economic entities to redistribute economic value in their favour. Regional competitiveness is interpreted as a form of competitiveness, occurring when regions acquire economic subjectivity. Such subjectivity is characterised by the presence of separate material interests, authority and regulatory powers resulting from the transformation of regions into elements of the productive forces of society. This creates competition between regions for investment resources necessary to achieve regional goals. Regional competitiveness is defined as the ability of a region to redistribute investment flows in its favour by creating an attractive environment and incentives for their application. The given interpretation, which adequately describes the nature of regional competitiveness, has a number of advantages, such as syntheticity, sustainability, flexibility and operability.

Published: March 2024

Radiation-induced lung injury (RILI) frequently occurs as a complication following radiotherapy for chest tumors like lung and breast cancers. However, the precise underlying mechanisms of RILI remain unclear. In this study, we generated RILI models in rats treated with a single dose of 20 Gy and examined lung tissues by single-cell RNA sequencing (scRNA-seq) 2 weeks post-radiation. Analysis of lung tissues revealed 18 major cell populations, indicating an increase in cell-cell communication following radiation exposure. Neutrophils, macrophages, and monocytes displayed distinct subpopulations and uncovered potential for pro-inflammatory effects. Additionally, endothelial cells exhibited a highly inflammatory profile and the potential for reactive oxygen species (ROS) production. Furthermore, smooth muscle cells (SMC) showed a high propensity for extracellular matrix (ECM) deposition. Our findings broaden the current understanding of RILI and highlight potential avenues for further investigation and clinical applications.

El libro Climate Restoration: The Only Future That Will Sustain the Human Race sostiene que la restauración del clima, devolver los niveles de CO2 atmosférico a los niveles preindustriales, es una necesidad urgente para garantizar un futuro habitable para la humanidad. Las emisiones netas cero, el objetivo actual de la mayoría de los países, no son suficientes para revertir el daño que ya se ha hecho al clima. Los niveles actuales de CO2 ya han desencadenado cambios irreversibles, por lo que simplemente equilibrar las emisiones futuras no será suficiente. La restauración del clima es tecnológicamente factible y económicamente viable.

Published: March 2024

Buildings operational and maintenance can cause an increase in global warming, so it is necessary to apply the concept of green building. Most buildings in Indonesia are old buildings, so the Green Building Council Indonesia issues green building standards for existing buildings. The problems analyzed are the value of implementing green buildings in the Regional Library of East Java Province and recommendations that can be given after the assessment. The study method consisted of field observations, expert interviews, and a questionnaire survey with the Guttman Scale referring to the Greenship Existing Building version 1.0 using 12 of 41 criteria. There are 7 benchmarks for each criterion that have not been met, such as pedestrian facilities, percentage of softscape, provision of non-pet habitat, routine recording on kWh meters, operating and maintenance guides for air conditioning systems and electronic devices, collection and sorting of waste by type, as well as lighting that is less than the standard of SNI 03-6197-2000. The Regional Library of East Java Province received a Greenship Existing Building version 1.0 certification value of 26 points or 53.1% of 49 points. Recommendations are given so that the assessment benchmarks that are still not available can be met.

At the beginning of 2020, COVID-19 was a virus that spread and occurred simultaneously in various countries around the world, including Indonesia. This pandemic has an impact on sectors in Indonesia, one of which is the impact on education. With this pandemic, the government has implemented online learning until finally the government has implemented hybrid learning. This study's purpose is to determine whether this hybrid learning is effective in grade 12 students. Data collection was carried out in distributing questionnaires, interviewing grade 12 students and making direct observations to several schools. The results of our analysis show that hybrid learning for grade 12 students is considered less effective because students experience several changes in learning outcomes, understanding of the material and lack of communication between teachers and friends. However, because this research is still early, we will use the results of this study as the basis for further research where we will discuss the tools or products that are assembled regarding user needs in solving problems that occur in hybrid learning. Keywords -  Education, Hybrid, Pandemic, Student.

Published: March 2024

Contemporary architecture emerges from the desire and desire to get a new nuance due to the saturation of an architectural work that tends to be monotonous. The contemporary architecture itself has developed in line with technological advances and human needs in solving environmental problems in the future. Along with the development of development, the concept of sustainable development began to be recognized and one of its aspects is in the form of green buildings. The green building itself is part of the arrangement of a sustainable city where it is hoped that green buildings can provide benefits in reducing environmental damage as a result of the development process. One of the green building concepts that have become a trend lately is the vertical forest concept which this concept applies a combination of buildings by prioritizing harmony with nature and is applied vertically. This architectural work has become an anti-mainstream work that has been widely applied in several cities around the world. This evaluation aims to find out how far the application of the vertical forest concept is related from the perspective of contemporary architecture. The method used is descriptive qualitative, with hypotheses derived from a theory which is then tested for validity based on empirical data. This research is expected to be able to evaluate the application of contemporary architectural characteristics to the vertical forest design in the green building concept by Stefano Beori.

SSA2py: A High-Performance Python Implementation of the Source-Scanning Algorithm for Spatiotemporal Seismic Source Imaging
Authors: Fountoulakis Ioannis , Evangelidis Christos P.
Published: March 2024

This article introduces the first version of SSA2py (v.1.0)—an open-source package designed to implement the source-scanning algorithm (SSA). SSA2py is a Python-based, high-performance-oriented package that incorporates the SSA method, which has been effectively applied to numerous earthquakes for imaging the spatiotemporal behavior of the seismic source. The software supports a wide range of data and metadata resources. These include the International Federation of Digital Seismograph Networks Web Services, the SeedLink protocol, and others, ensuring optimal access to waveforms and station metadata. Furthermore, the code may evaluate the quality of accessible waveforms using signal analysis methods, allowing for the most appropriate data selection. The SSA method has been computationally optimized using multiprocessing techniques for efficient central processing unit and graphic processing units executions, enabling considerably accelerated computational processes even for large-scale grid searches. The program is also designed to provide statistical and methodological uncertainties for the executed cases through jackknife, bootstrap, and backprojection array response function tests. After appropriate tuning by the user, SSA2py can be used for detailed earthquake source studies that backprojection technique typically serves as a complementary output to the source inversion result or as a near-real-time tool for successful and quick identification of the style and complexity of the earthquake rupture. With a wide and flexible configuration, the user has complete control over all calculating aspects of SSA2py. This article provides a detailed description of the structure and capabilities of this new package, and its reliability is demonstrated through targeted applications to the 2004 Mw 6.0 Parkfield and 2019 Mw 7.1 Ridgecrest earthquakes. Furthermore, the computational efficiency of SSA2py is validated through rigorous performance tests.

Osteoarthritis is the most common chronic degenerative disease worldwide; it mainly affects elderly people. This disease can involve nearly any joint in the human body, and the most common symptoms include joint pain and disordered articular functions. Inflammasomes (NLRP3) which are induced by nuclear factor kappa B (NF-κB) signaling and can convert interleukin-1β (IL-1β) and IL-18 into mature proinflammatory cytokines are considered a factor in low-grade inflammatory pathology. This study aimed to explore the mechanisms underlying CDKN1A-in osteoarthritis. Chondrocytes were collected and isolated from 22 patients with osteoarthritis (average age 50.22 ± 2.15) and healthy volunteers (average age 51.12 ± 2.34) were enrolled as the control group from June 2021 to June 2023. mRNA expression levels of CDKN1A, NLRP3, and cleaved-Caspase1) were detected by real-time PCR. Cell activity was calculated with CCK-8. It has been found that CDKN1A regulates DNA damage repair, which contributes to the improvement of osteoarthritis by regulating the pyroptosis of cartilage cells. However, the exact mechanistic effects are still unknown.

Background: This study aimed to determine whether TNF-α and IL-6 gene polymorphism, their epistatic effects and haplotypes confer pathogenesis of PCOS in north Indian females.
Methods: A case-control study comprising DNA samples of 401 females (200 PCOS cases and 201 controls) of reproductive age. All the subjects were genotyped for TNF-α (-308 G/A) and IL-6 (-174 G/C) genes by tetra-primer ARMS PCR.
Results: There were 41.5% PCOS females revealing hirsutism, 45.5% acne and 36% alopecia. High BMI (p=0.008) and W/H ratio (p=0.0001) was observed among PCOS cases. Frequency of minor allele A for -308 G/A TNF-α was significantly higher in PCOS cases than controls indicating 1.4 fold increased risk for PCOS (p=0.05, OR=1.41, 95% CI=1.00-1.99). -174 G/C IL-6 gene was in association with the decreased risk of PCOS. The epistatic effects of all the possible combinations of both the SNPs shows statistically significant differences (Interaction p value=0.014) indicating modulating effects of TNF-α and IL-6 polymorphism in response to PCOS. Haplotype HT3 AG (p=0.003, OR=2.22, 95% CI=1.31-3.78) was associated with increased risk of PCOS.
Conclusions: The present findings suggest that TNF-α and IL-6 might contribute to pathogenesis of PCOS in north Indian females irrespective of a polymorphism of TNF-α (-308 G/A) and IL-6 (-174 G/C) genes.

Authors: Chandni  , Kumar Bind Nirbhay
Published: March 2024

Background: Approximately 22% of gynaecologic cancers are of ovarian origin, but 47% of all gynaecologic cancer deaths occur in women who have ovarian cancer. Ovarian cancer is usually diagnosed at an advanced stage because most of the symptoms are nonspecific, hence, the difficulty in diagnosis at early stages. In general, there is no effective screening test for ovarian cancer. Aim was to evaluate the ability of risk of malignancy index 4 (ROMI 4) to differentiate benign from malignant ovarian tumors.
Methods: A prospective observational study was conducted in April 2019 to march 2020.
Results: In the present study the ROMI 4 score at cut-off ≥ 450 had sensitivity, specificity, PPV and NPV of 74.3%, 65.3%, 42.6% and 88% respectively for malignant ovarian tumor.
Conclusions: Preoperative ROMI 4 score ≥450 will lead to rational basis for further referral to higher centre or gynaecology oncologist timely for appropriate surgical intervention/ management.

ABSTRACTThe main focus of assessment is student, and how assessments are used will contribute to students’ perception. Students’ perception of assessment can be influenced by various types assessment, and Curriculum 2013 facilitate a variety of assessment for learning. Research about perception that involves 36 boys and 46 girls was conducted for identify students’ perception of assessment and the reconciliation with the demands of curriculum assessment in 2013. Data collected through the use of a questionnaire that was developed from perception indicators, i.e. reproducing knowledge, rehearsing, accountability, improving learning, problem solving, and critical judgement. This study placed improving learning perception in the first position and the rehearsing perception at the sixth position.About 85% of students consider that assessment can develop their knowledge, but only 52% of students consider that the assessment made them practice before the exam. Even though 2013 curriculum demands assessment which strongly supports six perceptions of students, in this study only few assessments criteria have been addressed. Research finding shows that only a few demands of the assessment has been completed. Therefore, high level of improving learning perception in this study is closely related to the reconciliation with the demands of Curriculum assessment in 2013 that involved types of assessments during the learning. ABSTRAKPengguna utama asesmen adalah siswa, dan penggunaan asesmen secara tidak langsung akan membentuk suatu persepsi. Persepsi siswa terhadap asesmen didukung oleh berbagai variasi asesmen, dan Kurikulum 2013 memfasilitasi penggunaan beragam asesmen dalam pembelajaran. Penelitian tentang persepsi ini melibatkan 36 siswa dan 46 siswi bertujuan untuk mengidentifikasi persepsi siswa terhadap asesmen dan kaitannya dengan tuntutan penilaian pada Kurikulum 2013. Data dikumpulkan melalui kuesioner yang telah dikembangkan dari indikator persepsi siswa yaitu reproducing knowledge, rehearsing, accountability, improving learning, dan critical judgment. Penelitian ini menempatkan improving learning pada posisi pertama dan rehearsing pada posisi terakhir. Sebanyak 85% siswa menyatakan bahwa asesmen dapat mengembangkan pengetahuan mereka, namun hanya 52% siswa yang sepakat bahwa asesmen membuatnya menjadi rajin berlatih sebelum menghadapi ujian. Walaupun tuntutan penilaian Kurikulum 2013 memfasilitasi keenam persepsi siswa terhadap asesmen, namun alam penelitian ini hanya beberapa jenis asesmen saja yang terlaksana. Hasil temuan membuktikan bahwa hanya beberapa tuntutan asesmen yang dilakukan. Oleh karena itu, tingginya persepsi improving learning dalam penelitian ini sangat dekat kaitannya dengan tuntutan penilaian pada Kurikulum 2013 yang digunakan selama pembelajaran.
