Vertical pressure from vehicles on pavement reinforced with geocell develops radial and hoop stresses on geocell walls. Thin-walled cylinder theory is used to estimate the strain induced in geocell by some researchers. It is observed that thin-walled cylinder theory significantly overestimates induced strain when compared with experimental values. This paper presents non-accounted effect of lateral resistance mobilized due to geocell infill soil in computing strain by thin-walled cylinder theory. It is observed that computed strain values using thin-walled cylinder theory accounting lateral resistance match well with experimental results reported in literature. Equivalent thickness (teq) of geocell is then back-calculated by matching the experimental strain values with computed strain values using thin-walled cylinder theory accounting lateral resistance. As the thickness of geocell increases in the form of teq,thick-walled cylinder theory is also studied to analyze the strain induced in the geocell. Combined analysis is then carried out by modifying thick-walled cylinder theory equations using teqderived from thin-walled cylinder theory, and new factor named merging factor (M.F.) is introduced. Results of thick-walled cylinder theory with M.F. match well with experimental strain values reported in literature. Strain computed using modified thin-walled cylinder theory is validated with laboratory results of other researchers.

Soft kaolin clay is a problematic soils encountered in various construction projects that lead to the implementation of soil stabilisation. On the other side, the massive production of industrial and agricultural waste currently presents a critical problem for the environment. However, the utilisation of industrial and agricultural wastes in altering the characteristics of kaolinitic soil can be considered as an ideal solution to enhance the characterisation of problematic soils in the field of construction. Therefore, this study examines the alterations of the engineering properties of soft kaolin clay by utilising silica fume as the industrial by-product and eggshell ash as the agricultural by-product enhanced with lime use. To assess the impact of silica fume, eggshell ash, and lime on the various characteristics of kaolinitic soil, a series of laboratory experiments containing Atterberg limits, specific gravity, compaction test, unconfined compression test, X-ray fluorescence, X-ray diffraction, sieve analysis, and field emission scanning electron microscope is carried out. In this study, 2%, 4% and 6% of silica fume, 3%, 6% and 9% of eggshell ash and lime and the optimal combination of SF, ESA with 3%, 6% and 9% of lime are usedand were cured for 1, 7, 14 and 30 days. The results present that the optimal utilization of silica fume, eggshell ash, and lime can alter the engineering characteristics of the soft kaolin clay by reducing the specific gravity, consistency limits, linearshrinkage, and maximum dry density, while increasing the value of shrinkage limit, and optimum moisture content. In terms of strength improvement, the highest unconfined compression strength was recorded when soft kaolin clay was treated with 6% silica fume, 6% eggshell ash and 9% of lime for four (4) different days of curing with a strength improvement of 81.03%, 82.46%, 88.49% and 88.74%. Therefore, this study concludes that optimal use of silica fume, eggshell ash, and lime can persistently alter the characteristics of kaolinitic soil and open the way to economical and sustainable materials in improving the problem soil.

The success of any organisation depends on the effective and efficient utilisation of its human resources. In every project-based industry, such as the construction industry, project performance is tied to the effectiveness of its human resources. Labour turnover in the Nigerian construction industry and the poor performance of the Nigerian construction industry in terms of project delay, cost uncertainty, and quality deficiency is caused by inadequate utilisation of human resources management practices. The study aimed to assess the influence of human resources management practices on the organisational performance of construction firms in Lagos State in order to improve their competitive edge. A quantitative research method was adopted involving administration of 140 well-structured questionnaires to registered construction firms. The results revealed that human resources management practices (selection, training, development and reward) have a positive and statistically significant influence on organisational performance, with a p-value of <.001, <.003, <.003 and <.002 respectively. While the other practices (recruitment and compensation) did not significantly influence organisational performance. This indicates that human resources management practices are important to the success of organisations. Therefore, in order to overcome the challenges of labour dissatisfaction at work resulting from organisational instability, poor working conditions, lack of training, and reducing the low performance of the employees in the construction industry, appropriate and adequate human resources management strategies, policies, and action plan provisions should be put in place in order to improve organisational performance and to maintain competitive advantages.

The goal of this project is to use MATLAB software to efficiently calculate and visually represent the Energy Grade Line (EGL) and Hydraulic Grade Line (HGL) in fluid flow systems. This work serves as a practical showcase of our how MATLAB can be used to make Bernoulli calculations in the realm of civil engineering. In addition, the incorporation of Building Information Modeling (BIM) offers the potential to further enhance the design and analysis of fluid flow systems. The Energy Grade Line (EGL) holds a vital position in fluid mechanics, acting as a representation of a fluid's energy as it moves through a conduit. This blend of pressure, velocity, and elevation energy provides crucial insights into the behavior and characteristics of the fluid throughout its course. For engineers, the EGL is an essential tool, aiding in the analysis of fluid flow systems, identification of energy losses, and optimization of hydraulic structures. Furthermore, the Hydraulic Grade Line (HGL) represents another critical concept in fluid mechanics, graphically illustrating the pressure head of fluid along a specified route. It offers a clear depiction of energy distribution within a fluid flow system, accounting for the sum of pressure and elevation heads. Engineers heavily rely on the HGL to inspect pressure fluctuations, detect potential issues like pressure drops or excessive velocities, and make informed decisions to ensure fluid flow's efficiency and reliability. Thorough testing and implementation revealed that, with precise configuration of the MATLAB environment code, our code achieves high accuracy calculations for Energy Grade Line (EGL) and Hydraulic Grade Line (HGL) values. This setup also enables the generation of clear graphical representations, providing engineers with a reliable and visually accessible graph for fluid flow system analysis.

The easy installation of the solar energy system, no need for fuel, low maintenance and operation requirements, makes it the preferred choice to solve the problem of power outage especially in the day of the summer season. The downside of the solar energy systems is decreasing the generated energy with the rising in temperatures, perfect and simple design of the solar energy system makes it durable over a wide range of temperature increases. This research presents the design of 3-ph (380V, 39A) stand –alone solar system at latitude 32.5 with a high quality voltage and current even when the temperature reaches to maximum levels. The power system of the project contains: 60 PV modules of a half cut cell to reduce the losses in connection lines, and two Mn-Zn toroid core ferrite transformers to transition the solar energy to the inverter with appropriate voltage efficiently. Control system is implemented based on PI controllers for switching function at a certain values of a modulation index parameter (m). The system is modeled and simulated in MATLAM/Simulink, simulation results demonstrate that the rated voltage and current have been obtained with minimum values of Total Harmonics Distortion (THD) and modulation index parameter less than 1.

Silicon-based solar cells suffer from different types of light-induced efficiency losses (can cause up to 10% loss), known as light-induced degradation (LID). Impurities, such as boron, iron, and oxygen, are common at different concentrations in these solar cells. They form active recombination defects in boron-doped mono-crystalline (Cz-Si) and multi-crystalline (mc-Si) solar cells during illumination. For the solar industry, this will lead to serious financial loss, hence the importance of inspecting and controlling the LID level accurately. Seeking to minimize the human factor and the inaccuracy that comes with it, we have proposed in this research a low-cost virtual instrumentation solution to provide a new real-time instrumentation technique for solar cell characteristics such as open circuit voltage (VOC). The virtual data acquisition system (VDAS) design is based on a low-cost Arduino board associated with MATLAB/Simulink software. Moreover, this system can collect in real time the values of solar cell outputs under prolonged illumination and under different temperatures of the LID test. Further, kinetic modeling of the solar cell output VOC variation as a function of light soak duration; shows the predominance of one type metastable defect over the LID test of c-Si solar cells. Additionally, degradation mechanism in mc-Si solar cells involve more than one metastable defect and are more complexes due to the mc-Si substrate elaboration technique compared to c-Si substrate. Furthermore, the temperature dependence of the concentrations (NVoc) and the thermal activation energies of the defects have been extracted from the experimental VOC measurements obtained using the VDAS. Finally, the system minimizes the test period and errors for solar cell characterization compared to traditional approaches.

Published: January 2024

Resistance of Portland cement pastes incorporated 20 wt. % sanitary ware ceramic nano-powder wastes to firing temperatures from 100 up to 600 ℃ was investigated. Results revealed that all physical and mechanical properties were improved and gradually enhanced with firing temperatures, but only up to 400 ℃, and then adversely affected with any further increase of firing temperatures than 400 ℃, i.e. water absorption and total porosity decreased, whereas bulk density was enhanced. Water absorption and total porosity were decreased by 10 and 4 %, respectively, while bulk density was increased by 2.25 %. Furthermore, flexural and compressive strengths were also improved and increased by 1.69 and 1.2 %, respectively. Fourier transform infrared spectra (FT-IR) showed the disappearance of free lime and ettringite on firing. Scanning electron microscopy (SEM) showed that the crystal phase growth of the formed hydration products as a result of both normal hydration and pozzolanic reactions at ambient temperature were developed and modified due to the temperature exposure. The hardened cement pastes can withstand and resist only up to 400 ℃.

Authors:   Universiti Kebangsaan Malaysia, Shahida S. , Fuad Siti Hanisah ,   Universiti Kebangsaan Malaysia
Published: January 2024

In Islam, the preservation of environment is one of the fundamental in maqasid al-shariah (objectives of shariah). As world’s leading hub of Islamic finance and the second largest palm oil producer, a positive respond on environment preservation had been given by Malaysia towards sustainable palm oil industry. Moreover, almost 70% of Malaysian palm oil companies are complied with shariah. It is necessary to the shariah compliant companies to put into consideration regarding environment sustainability in their main objective of the firms. Therefore, Malaysia urges these companies to adopts Roundtable on Sustainable Palm Oil (RSPO) and Malaysian Sustainable Palm Oil (MSPO) certifications which ensure sustainable operation and production of certified palm oil. However, these companies have concern on profitability over sustainability due to additional cost to subscribe the certification. Therefore, this study is conducted to identify the effect of the sustainability certification on the profitability of 29 shariah-compliant palm oil companies listed in Bursa Malaysia from 2013 to 2017. It is important to provide evidence on certified companies’ profitability to encourage more adoption of sustainability certification, promote sustainable practices and increase production certified palm oil among shariah compliant companies. The results of generalized least squares (GLS) regression show that certified companies enjoy profits that are 2.3% higher than those of non-certified companies. These findings support the sustainability policy in palm oil industry by the Malaysian through MSPO certification which became mandatory in late 2019.

Published: January 2024

Green chemistry is an important learning approach that provides education on environmental sustainability through the implementation of 12 principles introduced since the late 1990s. However, the success of this approach depends on the level of students' knowledge of all the principles contained in green chemistry. This study aims to examine the level of knowledge of the three principles of green chemistry among fourth grade students who take chemistry subjects at school. The three principles are prevention, atom economy and the use of raw materials from renewable sources. A qualitative study was conducted involving 80 high school students. A set of questions for the Knowledge Test _Kimia Hijau (UP_KH) was administered in this study. The data was analyzed by content analysis. The findings of the study show that students have a low knowledge of the principles of green chemistry, namely prevention, atom economy and the use of raw materials from renewable energy sources. Students' knowledge of the principle of prevention is general to prevent environmental pollution. It focuses on three general aspects namely legal action, campaigning and waste management. Pupils have low knowledge in the principle of economic atoms and cannot make the correct connection between the value of economic atoms and the level of effectiveness of a reaction. Students' knowledge was also found to be low regarding renewable raw material sources and the importance of their implementation in a chemical reaction. Knowledge about the principles of green chemistry is very important to give early exposure to students about the need for early-stage prevention to overcome environmental pollution problems.
Network Analysis and Control System in Mega Projects: The Case of PICASP Erasmus Project
Authors: Bianchi Massimo
Published: January 2024

Network Analysis achieved some significant results in recent years thanks to advances in technology and in the approach to organisational networks. Less exciting were the results obtained with Mega Projects. These projects show high risk with regards to results, to the compliance of the budget and to the realization of the entire project. So far, the response of Mega Projects contracting authorities is to ask those presenting the project proposals to increase the number of controls and connected indexes without obtaining, almost until now, an increase in project performance. This paper examines the proposal to transfer some results of network analysis to the performance monitoring of Mega Projects. Starting from the case of Erasmus PICASP Project for the creation of Pilot courses and new didactics for teachers training in cultural tourism for the development of Caspian Area, the paper proposes an evolutionary model of cycles of simplification and complexification of the networks control systems. The approach of Practice Enterprise which allows the members of the project networks to acquire the practice of teamwork right from the early stages of planning, and, once the project starts case risks or emergencies arise, will be applied within his model.

ADR and Workplace Conflict - A Podcast Analysis Nigeria, Britain and the US
Authors: Egbunike-Umegbolu Chinwe
Published: January 2024

The decline of union representation and the introduction of legal incentives for workers to resolve individual employment disputes without resorting to the courts has unequivocally made Alternative Dispute Resolution (ADR) increasingly prominent in the British industrial relations landscape. The conciliation service offered by the Advisory Conciliation and Arbitration Service (ACAS) has been the most important sign and driver of this change. Although ADR has been encouraged in Western jurisdictions, particularly in the United Kingdom (UK) and in the United States (US), as a means to reduce time and litigation costs in relation to employment tribunal claims, the scarcity of scholarly publications, particularly on the benefits of utilising mediation or conciliation to settle workplace disputes is frankly unacceptable. On the other hand, Nigerian workers or employees are not encouraged or have little or no awareness of resolving workplace disputes or conflicts via ADR due to a lack of sensitisation in most organisations and a dearth of scholarly research on ADR to settle conflicts or workplace disputes in Nigeria, particularly with Mediation and Conciliation. This lack of awareness is a grave oversight compared to the UK. While British workers are encouraged to lodge their disputes with the Advisory, Conciliation and Arbitration Services (ACAS) before proceeding to an employment tribunal claim, Nigerian counterparts settle via the National Industrial Court (NIC) ADR, which is not always adequate. However, some sectors in Nigeria, like the Trade Unions, are quite complex, particularly disputes emanating from the Maritime Industry, which are hardly settled via ADR, unlike their UK counterparts. Hence, the jurisdictions mentioned above have different patterns and modus operandi for resolving workplace conflicts or disputes, and these will be meticulously examined in this paper. Additionally, the paper scrutinises the reason why the minister of labour and employment has so much power accorded or bequest to him to apprehend and refer a disputed award to the National Industrial Court (NIC) ADR. The paper employs a comparative and, for the first time, podcast analysis of workplace disputes in Nigeria and Britain, focusing on the different patterns of settling Workplace Conflicts such as discrimination, bullying and harassment. The paper concludes by unequivocally highlighting the benefits of mediation and its relevance to various entities involved in Workplace conflicts or disputes.

THE EFFECT OF COMPANY SIZE, FUNDING DECISIONS, AND FINANCIAL PERFORMANCE ON FIRM VALUE
Authors: Ismanto Juli
Published: January 2024

This study aims to determine the effect of company size, funding decisions, and financial performance on firm value. Secondary data is sourced from the financial statements of companies in the Industrial Goods sector index companies listed on the IDX during the 2017-2021 period. The number of samples used was 40 companies as research objects for five years. Panel data regression analysis was used as a mechanism in this study. The results showed that firm size significantly affects strong values with a negative coefficient direction. On the other hand, funding decisions and financial performance do not affect firm value. Therefore, it is concluded that fit size has a significant effect on solid buy with a negative coefficient direction, indicating that the larger the size of the company, the greater the agency costs that the company must incur to overcome agency problems and diversify into products that are less profitable and absorb a lot of resources, so this can reduce the value of the company.

Published: January 2024

This study aims to investigate and analyze the influence of Islamic corporate governance (ICG) and Islamic corporate social responsibility (ICSR) on the performance of Sharia Commercial Banks in Indonesia during the five-year period from 2014 to 2018. The financial performance of the banks is assessed using the return on assets (ROA) and return on equity (ROE). Employing a purposive sampling method, data was meticulously collected from a sample of 11 Sharia Commercial Banks. Employing a quantitative research approach, the study employs multiple regression analysis to discern the relationships between the variables. The results reveal that Islamic corporate governance (ICG) does not wield a significant effect on the financial performance of Sharia Commercial Banks, as represented by the variables ROA and ROE. However, in contrast, Islamic corporate social responsibility (ICSR) demonstrates a positive and significant impact on the financial performance of Sharia Commercial Banks, as indicated by the proxies ROA and ROE. These findings contribute to the understanding of the complex interplay between governance, social responsibility, and financial performance in the context of Islamic banking, providing insights for both practitioners and scholars.

Market risk and credit risk play a central role in destabilizing company stability. Market risk manifests when the value of investments declines due to a decrease in market value, while credit risk arises when funds allocated by the bank to customers are not repaid according to the loan agreement. This study aims to explore the impact of market risk and credit risk on financial performance, applying an Associative-based Quantitative Method. The data used are quarterly secondary data from Bank Panin Dubai Syariah from 2014 to 2021. The sampling technique used is saturation sampling, given the relatively small population, with a total sample of 32. The analytical tests involve Descriptive Statistical Analysis, Classical Assumption Tests, Multiple Regression Analysis, T-Test, F-Test, and Determination Coefficients. The research findings show that, partially, Market Risk (NOM) has a significant influence on Financial Performance (ROA), while Credit Risk (NPF) does not have a significant impact on Financial Performance (ROA). However, simultaneously, both Market Risk (NOM) and Credit Risk (NPF) significantly influence Financial Performance (ROA)

Amidst the global push for sustainability, the burgeoning electric vehicle (EV) industry has driven increased demand for batteries, placing the Indonesian nickel ore sector in a pivotal position due to its vast reserves. This study thoroughly examines the investment landscape of this sector, utilizing advanced portfolio optimization techniques to analyze four major nickel ore mine firms in Indonesia. Through Monte Carlo simulations, the study evaluates the optimal portfolios of risky assets, comparing their performance before and during the COVID-19 pandemic. Findings reveal a significant shift in portfolio composition during the Pandemic, reflecting investors' response to global disruptions by diversifying their holdings. Notably, the Sharpe Ratio, a risk-adjusted return measure, demonstrates an impressive increase in return relative to risk during the Pandemic, emphasizing the sector's resilience and attractiveness for investment, especially in times of economic uncertainty like the COVID-19 pandemic. The transformation in portfolio weights and the corresponding increase in risk-adjusted returns highlight the sector’s potential as a lucrative investment avenue, especially during periods of global economic uncertainty like the COVID-19 pandemic.
Exploring Employee Perceptions of Technology Media Influence on Supervisory Relationships
Authors: Fairweather Jennifer , Bilodeau Julie
Published: January 2024

Research has shown that the relationships employees have with their supervisors or managers is one element that may influence employee engagement and retention. As part of building a positive relationship, communication may be a key factor of influence. In today’s workplace, supervisors often use technology to communicate with direct reports. With the increasing use of technology to communicate, there could be influences on the perceived relationship employees have with their managers, with various media having different levels of impact. The purpose of this convergent mixed methods study was to determine which technology media are perceived to be most and least effective in fostering a positive relationship between direct reports and their supervisors. The full range leadership model (Bass & Avolio, 1994) provides a theoretical framework for this study and describes various leadership styles and their effectiveness in motivating employees. Specifically, within the full range leadership model, the transformational leadership style may be an effective approach toward engaging employees that could also be influenced by technology media. Our findings indicate that technology media may be especially helpful in bolstering the availability of supervisors, which may positively influence other elements of the supervisory relationship. The results further suggest that it may be important for all leaders to choose a technology medium that is personalized and preferred by the employee while also using the most effective medium for the type of message. Finally, leaders should understand the concerns that employees may have around privacy and the overuse of technology media.
Frantz Fanon’s Political Thought on Tabula Rasa A Recommendation for Racial Justice.docx
Authors: NDAYISENGA ZENON
Published: January 2024

  

Abstract

Fanon’s political thought on tabula rasa is highly still in demand by the racialised subjects who continue to daily experience racial injustice. Uniquely, his political thought on how the racialised black subjects should be free, is still relevant to contemporary politics in a sense that it resonates with the current political and racial problems. Fanon remains distinctive in his dialectics, as his dialectics have the potential to create the conditions for existential lives for the racialised black subjects. Using qualitative as an approach, this article justifies such a distinctiveness based on the fact that Hegel's and Marx’s dialectics are limited to an end, while Fanon’s dialectics are renewal and continual—linked to an enduring struggle. This is the recommended struggle—a highway for racialised black subjects to durable racial justice for all. Based on the fact that tabula rasa is explained as a potential tool for the creation of a new beginning and new humanism, this article elucidates that genuine and durable racial justice for all cannot happen without the intervention of tabula rasa. Why? Because, for Fanon, tabula rasa disposes of the minimum of what the oppressed and racialised subjects have willed, called for, or demanded.

Published: January 2024

Rapid electrification of society is placing unprecedented demand on critical mineral and metal resources. New strategies and technologies are thus needed to promote mineral discovery in regions where deposits are likely buried deep under soil and glacial till. We show that microbial communities from different soil types change in composition in response to amendment with copper. We also show that soil microbial community fingerprinting can detect buried sulfide mineralization through thick successions of Quaternary surface cover. Indicator species abundances, indeed, better resolve the known surface projection of mineralization than geochemical analyses. Therefore, our results indicate that porphyry-style mineralization is discernible in covered terrains through soil microbial community fingerprints.
Using Quantitative Methods in Equity and Demographic Analysis to Inform Transit Fare Restructuring Decisions
Authors: Hickey Robert L. , Lu Alex , Reddy Alla V.
Published: January 2024

New York City Transit (NYCT) and the Metropolitan Transportation Authority (MTA) have integrated race and income equity considerations into its extensive public outreach processes for fare changes. Responding to Federal Transit Administration’s (FTA) Civil Rights/Title VI and Environmental Justice (EJ) requirements, NYCT developed two different quantitative and analytical approaches for forecasting equity impacts of fare restructuring decisions, in place of more traditional origin-destination surveys. The first approach uses standard aggregate fare elasticity models to estimate diversions between different fare classes and ridership losses resulting from fare adjustments. Average fare changes by fare media type are disaggregated with historical farecard usage patterns (consumption data) by subway station and bus route, and translated into demographic variables (minority/non-minority, and at or below/above poverty) based on Census data. Overall average fare changes are used to analyze equity impacts. A second, more experimental approach identifies user demographics by daily first swipe locations, and estimates daily average fares as actually experienced by each passenger using sequential transactions on discrete farecards. To meet ongoing requirements, methods were developed to analyze impacts separately for peak and off-peak time periods, and to demonstrate equity using statistical tests. Impact analyses results, and historical ridership, revenue, and market share data collected by the MetroCard Automated Fare Collection (AFC) system all inform fare structure design processes, with particular attention being devoted to distributing fare increase burdens equitably.

Published: January 2024

In Nepal, due to rapid urbanization, there are many emerging towns and settlements near highways, which have raised issues of increased traffic density resulting in frequent road crashes like in Kotre- Aabhukhaireni section of Prithvi Highway. Higher crash rates depict lower safety conditions. To improve safety conditions and reduce the loss of life and property, hazardous conditions along the highways need to be identified and ranked for treatment purpose. This study is based on a methodological framework for identifying hazardous locations based on a Field Survey (condition rating) and Analytical Hierarchy Process (AHP) for ranking road safety hazardous locations of Kotre- Aabhukhaireni road Section of Prithvi Highway by weighing the safety parameters of the road section and calculating the Safety Hazardous Index (SHI). Field condition rating with a focus on pavement surface conditions, structural conditions, shoulder and drainage conditions, pedestrian infrastructure and vehicle restraint system, street lighting, traffic signs, island and road marking conditions was conducted, and risk factors were identified by comparing these variables against norms.

The study identified 15 different locations as safety hazardous locations. The results showed Yampa, Baradi, and Chirrkeni as the most hazardous ones with an SHI index of 0.852, 0.773 and 0.712 respectively, among the study section considered. In contrast, Dhaaptar was considered as the least hazardous one with SHI value of 0.210.

Published: January 2024

This research study aims to evaluate the effectiveness of transfer learning with the ResNet50 model for classifying CT scan images of lungs as having cancer or not. Additionally, it explores the interpretability methods of LIME (Local Interpretable Model-Agnostic Explanations) and SHAP (SHapley Additive exPlanations) to provide explanations for the predictions made by the ResNet50 model on CT scan images. The research objectives include developing a deep learning model based on the ResNet50 architecture, evaluating its performance using various metrics, and explaining the predictions using LIME and SHAP techniques. The dataset consists of a collection of CT scan images of lungs, with labels indicating the presence or absence of cancer. Through k-fold cross-validation, the model achieves high accuracy and low loss, demonstrating its effectiveness in classifying lung cancer. The interpretability methods of LIME and SHAP shed light on the crucial features and regions in the CT scan images that contribute to the model's predictions, enhancing the understanding of the model's decision-making process. The results highlight the potential of transfer learning and interpretability techniques in improving the accuracy and explainability of lung cancer detection models. Future directions may involve applying the developed model to larger datasets, classifying different stages of cancer, and identifying the specific regions within the lungs where cancer cells are detected.

Introduction: Red blood cells contain antigens on its membrane which are inherited according to Mendelian Law. Despite the identification of more than 400 red blood cell antigens, ABO and Rhesus blood group systems are clinically most significant. The current study aimed at determining the distribution of blood groups among different caste and ethnic groups of Western Nepal.
Methods: A descriptive cross-sectional study conducted among individuals in the Blood Bank of Department of Pathology of a Teaching Hospital from January 2018 to July 2019. Ethical approval was taken from the Institutional Review Committee (Ref. 384). Convenient sampling was done. Data were entered in Microsoft Excel and analysed using Statistical Package for the Social Sciences version 21.0. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data.
Results: In ABO system, the frequency of O, A, B and AB blood groups were found to be 960(33.9%) (95% Confidence Interval= 32.15-35.64), 930(32.8%) (95% Confidence Interval= 31.11-34.57), 716(25.3%) (95% Confidence Interval= 23.68-26.88) and 226(8.0%) (95% Confidence Interval=6.98-8.98) respectively. Rh positive was the dominant Rhesus blood group, 2758(97.4%) (95% Confidence Interval=96.73-97.94). Blood group O was dominant in Brahmin, Bishwakarma, Gurung, Pariyar, Tamang, Terai Brahmin and Limbu.
Conclusions: The frequency distribution pattern of ABO blood group was observed as blood group O>A>B>AB. Variation in the blood group distribution was observed in different ethnic groups.

Introduction: Burn injuries are a significant public health concern with immediate and long-term consequences. This study assessed the knowledge, attitude, and practice of burn first aid among medical interns in a tertiary care center.
Methods: A descriptive cross-sectional study was conducted among medical interns at a tertiary care center. A structured questionnaire was used to collect data on the burn first aid knowledge, attitude, and practical skills of medical interns. The data were analyzed using appropriate statistical methods.
Results: The study involved 89 medical interns aged between 23 and 29 years, with 60.7% male participants. Of them, 51(57.3%) reported no prior exposure to burn and 17(19.1%) received formal training in burn first-aid priorly. The study found that 85 participants had good knowledge (95.5%), with only 4.5% having poor knowledge. Attitude assessment revealed 66(74.16%) participants had unfavorable attitudes, while 25.84% had a favorable attitude towards burn first aid. All participants had a good level of practice.
Conclusions: The study emphasizes the need for targeted interventions to enhance burn first aid KAP among medical interns in tertiary care centers, including structured training programs, continuing medical education, positive attitudes, and hands-on practical skills training.
Landslide Susceptibility Analysis of Jugal Rural Municipality, Sindhupalchok
Authors: Pradhan Prateek , Dahal Bhim Kumar
Published: January 2024

Hilly and mountainous areas of Nepal, with challenging terrain, young geology, and heavy monsoon rainfall, are susceptible to landslides and slope instability. To analyze and prepare landslide susceptibility maps, this study selects a typical hilly area, the Jugal Rural Municipality in Sindhupalchok district. Twelve factors contributing to landslides were considered, including slope, aspect, elevation, geology, land use, proximity to roads and drainage, plan curvature, profile curvature, NDVI (Normalized Difference Vegetation Index), soil type and rainfall. Moreover, 286 landslides were identified using high-resolution satellite imagery and field verification as the landslide inventory. These landslides were then randomly divided into two sets: 70% for training and 30\% for validation. Bivariate statistical analysis was performed using factor maps and the landslide inventory map. Notably, the analysis revealed a Prediction Rate (PR) of 9.35 for 'Land use', the highest among all factors considered. Since land use is a dynamic factor, we recommend conducting an analysis of land use changes and their impact on landslide susceptibility. Such an assessment would be invaluable during the planning and execution phases of development projects in Nepal's disaster-prone regions.

The human reference genome assembly has been available for two decades, and advancements in sequencing technology have enabled rapid whole-genome sequencing in single institutes. WGS (whole-genome sequencing) data analysis applications will enable large-scale data analysis on multi-clouds, integrate datasets with a population scale, and ensure the reproducibility of publications through modern workflow engines and scalability. In human genetics, expert-knowledge-driven approaches from medical and biological professionals and data-driven approaches from computer science applied to epidemiology, such as AI (artificial intelligence), are required for domain-specific downstream data interpretations. For reliable diagnostic, prognostic, and therapeutic tools, as well as generalized outcomes, genomic studies should involve a wide range of majority and minority populations. The field of genomics in medicine is entering a new era, and to increase the application of gene therapy in the treatment of emerging infections and disorders, there needs to be a united worldwide effort.

Head Teacher's Job Satisfaction: At Community Schools in Dadeldhura District
Authors: Ghimire Durga Devi
Published: January 2024

In the current situation, job satisfaction is one of the most important issues in organizational and leadership studies because it directly impacts individuals' sense of commitment to their job and belonging in the workplace. However, there is currently no general agreement in the educational research on job satisfaction and its definition. This was a quantitative approach with the survey research design method. For this, the questionnaire was used to collect data. There were 57 head teachers as the sample from the Dadeldhura district. A questionnaire was sent via e-mail to collect data, and collected data were analyzed using SPSS 25 version chi and phi as the test. About fifty and fifty percent of males and females are head teachers. Most of them were from the village area with Master’s degree qualifications. The p-value of males and females in salary satisfaction was found to be 0.14, which is not significant. Similarly, the p-value of age and professional satisfaction was 0.45 which is also not significant. Fifty percent of head teachers were males and females which is good. Likewise, 76.7% of the head teachers have Master’s great degree qualifications. More than 66% of the head teachers were satisfied with their co-workers working happily which can be interpreted as a good result in comparison to others. Most of the head teachers were from the village area of the Dadeldhura district. Females are also capable to get as higher a position as males that also reflected that the salary satisfaction level of males and females was not significant in terms of age and professional satisfaction.
