Most schools have used information technology (IT) to enhance and advance their various educational methodologies to attract more learners. Institutions have implemented IT to facilitate E-learning and mobile learning, enhancing the cost and versatility of educational offerings. Most educational institutions are providing online instruction using technology such as cloud computing (CC) and networking. Educational institutions have established their own E-Learning Systems (ELS) to facilitate online learning, enabling remote education. However, ELS must confront several security concerns related to hacks and data breaches via unauthorized entry. Also, a novel idea of Internet-based ELS architecture has emerged to enhance service proximity to the customer. This research presents a novel CC and Internet-based ELS system. This study proposed the implementation of Integrated Encryption Methods (IEM), which incorporates two encryption algorithms, Rivest-Shamir-Adleman (RSA) and Advanced Encryption Standard (AES), to meet the safety and latency requirements for communication among the CC and the ELS. The suggested technique explicitly extends learning material from the CC to the network's boundary. It enhances the effectiveness of instructional data analysis, alleviates the computational cost of encryption on users' devices by delegating some of the encryption workload to CC servers, and offers limited access to educational material via the encryption of courses and examinations using IEM. Security research indicates that the proposed approach can accomplish information privacy, precise access management, and resistance to conspiracy. Performance studies illustrate the efficacy of the proposed framework, particularly regarding IEM computational costs.

Authors: Urriquia Lady Lyn
Published: December 2024

The study investigates the mediating effects of work values on the roles and qualities of school leaders and teachers' core behavioral competencies. The research involved 100 public elementary school teachers from nine Del Remedio District, Division of San Pablo City schools, with the majority being female and married. The study used descriptive and correlational research methods to determine the relationship between leadership roles, qualities, and teacher performance. The questionnaire was divided into five parts: respondent profiles, perceptions about the mediating effects of work value in the roles and qualities of school leaders and teachers, and core behavioral competencies. The findings show a significant relationship between leadership roles and qualities and teacher performance and between teacher work values and performance in core behavioral competencies. Teachers' work values fully mediate this relationship. The study suggests that school leaders should be knowledgeable about their roles and qualities, provide necessary technical assistance, and prioritize professional growth for the benefit of the school. The Department of Education is actively working to develop these roles and qualities for better teacher performance.

Based on these considerations, this research aims to examine the Sufism thought of Sheikh Abdur Rauf as-Singkili and its relevance in facing modern challenges, such as materialism, consumerism, individualism, and cyberbullying that are rampant today. This research uses the literature study method, in which researchers collect, examine, and analyze various relevant sources to understand and dig deeper into his tasawwuf thought. Sheikh Abdur Rauf's tasawwuf thought includes his reinterpretation of the concept of wujudiyyah, the reconciliation of tasawwuf and sharia, the importance of dhikr, and the emphasis on morals based on reason. He emphasized that moral actions must always be based on reason, because reason allows humans to evaluate good and bad behavior. It is concluded that Sheikh Abdur Rauf's Sufism offers relevant solutions to modern challenges. His thought or concept of Sufism emphasizes that true happiness lies in inner peace and harmonious relationships with God and others. With this principle, humans can avoid excessive attitudes such as materialism and consumerism. In addition, the role of reason emphasized by him allows individuals to think carefully before acting, so as to prevent the negative impact of materialism, consumerism, individualism and behaviors such as cyberbullying that can harm themselves and others.

Limestones in Amphoe Bueng Samphan, Phetchabun, contain not only abundant coral building animals, Brachiopods, Mollusca, Rugosa, Ammonoids, Calcareous sponges and Bryozoans, but fish fossils. The discovery was in the course of field work II. First of all, I prepared the geologic map and classified geomorphic surfaces in study area scaled 25,000 and determined stratigraphical position of fish fossil localities. And after that, by using lithology and sedimentary structures in limestone. paleoenvironments are reconstructed. Fish fossils are two horizons. The first one is the same locality with Crinoid limestone (Horizon 1). The color of this limestone is reddish purple and orients to the layer parallel to bedding plane. The other one is in the alternation of limestone (100-200 cm.) with black shale (10-20 cm.). This limestone has laminated partly, on the upper surface, trace fossil of creeping animal are observed. Expected microenvironments are lagoonal swamp with some times invasion of fresh water. This groups originated from fresh water environments. So, according to explosive evolutional trend, they may extend to marine environments. It is important to collect more samples and precise taxonomy. Fish fossils are mostly the surface of body, hard diamond scales. They are lacking the skull, according to the characteristics of fish scale, fish fossils are belonged to Osteichthyes ( Class ), Chondrostei ( Superorder ), Palaeochondrostei ( Superorder ), Paleonisciforms ( Order ). These group is characterized by the characteristic “Ganoid” scale. Like these fish fossil had been refered from China (Lu and Ma,1973)
Peran Organizational Citizenship Behavior (OCB) dalam Peningkatan Kinerja Karyawan : Sebuah Kajian Literatur
Authors: Kiki Nur Azizah
Published: December 2024

This study aims to conduct a literature review examining the influence of Organizational Citizenship Behavior (OCB) on job satisfaction and employee performance. Through a thorough analysis of relevant literature, this article presents significant findings from previous research. The analysis of three relevant journals reveals that OCB has a significant positive influence on job satisfaction. When employees voluntarily engage in OCB behaviors that go beyond their formal job responsibilities, it tends to enhance their job satisfaction. Additionally, OCB is positively related to employee performance. Employees who engage in OCB behaviors tend to achieve better performance in various aspects of their work. In the context of education, OCB also plays a crucial role in improving teacher performance and creating a productive learning environment. Previous studies have shown that teacher OCB behaviors, such as assisting fellow teachers, providing emotional support to students, and actively participating in extracurricular activities, contribute to enhanced teacher performance and student academic achievement. This article provides an in-depth understanding of the importance of OCB in enhancing job satisfaction and employee performance. To create a positive and productive work environment, organizations need to encourage and appreciate OCB behaviors through recognition, appreciation, and increased participation opportunities. Although previous research findings demonstrate a positive relationship between OCB, job satisfaction, and employee performance, it is important to note that further research is needed to gain a deeper understanding of the factors influencing OCB and the best strategies for fostering OCB behaviors in the workplace. Through a greater understanding of OCB, organizations can create a positive and empowering work environment where employees feel satisfied with their jobs and achieve optimal performance.
THE QUALITY OF ENVIRONMENTAL FACTORS AND ORGANIC AGRICULTURE
Authors:   Institute of Agricultural Economics, Romanian Academy, Bucharest, Romania, ROȘU Elisabeta
Published: December 2024

Greenhouse gas emissions are the main cause of the global climate crisis. The EU is the fourth largest emitter of greenhouse gases in the world, after China, the United States and India, which determined the setting of the Community objective of reducing emissions by 55% by the year 2030 and reaching climate neutrality by 2050. In Romania, agriculture ranks second in terms of greenhouse gas emissions and can play an important role in ensuring its own climate neutrality and can contribute to neutralising the effects produced by other anthropogenic activities. The quality of environmental factors influences the quantity, but especially the quality of food. Organic agriculture is an essential tool in protecting the quality of the environment, by conserving soil, water quality and supporting biodiversity, but also a tool in ensuring a healthy diet. The paper is intended to be an analysis of the quality of the main environmental factors and evolution of organic agriculture in Romania.

In this research work, bi-harmonic slant sub-manifolds in space forms have been studied. Bi-harmonic maps are critical points of the bi-energy functional and are of great importance due to both analytical and geometrical characteristics. After the study of Riemannian Manifolds with complex and contact structure and s-space form structure along with slant sub-manifolds theory, some significant developments related to bi-harmonic slant submanifolds in space forms have been established. Manifolds with constant sectional curvature is known as space form. As s-space form is the generalization of complex and contact structure, we get generalized results. Different aspects of results have discussed.

An accurate Spatial Temporal Graph ATtention Network for pedestrian trajectory prediction
Authors:   Harbin Engineering University, School of Computer Science and Technology, Harbin, 150001, China, ZHANG Yanbo , ZHENG Liying ,   Harbin Engineering University, School of Computer Science and Technology, Harbin, 150001, China

Pedestrian trajectory prediction has broad applications to target tracking and autonomous driving. Although current research has gradually shifted from handcrafted-based approaches to deep learning-based approaches, existing predictors sometimes produce wrong future trajectories, and their performance is still unsatisfied. This paper improves the Spatial Temporal Graph ATtention Network (STGAT) for trajectory prediction by adding two Multi-Layer Perceptron (MLP) modules and three Gated Recurrent Units (GRUs) to the original predictor. Specifically, the model uses an MLP to process the position and velocity of a pedestrian to obtain high-dimensional embedding features. Then, to improve prediction accuracy, the model uses a GRU and a Long Short-Term Memory module (LSTM), i.e. GRU-LSTM, to obtain the motion features of the individual pedestrian. Next, the interaction information between the target pedestrian and his/her neighbors is captured by a Graph ATtention (GAT) module. Here, to reduce the redundant information in the GAT, another MLP is used to map the high-dimensional features to low-dimensional ones. Next, the second GRU-LSTM further encodes the interaction features from the GAT. Finally, the third GRU-LSTM serves as a decoder to give the future trajectory of the target pedestrian. To generate multiple socially acceptable prediction results, the model adopts the variety loss. Test results on the public ETH and UCY datasets illustrate that the proposed model outperforms the state-of-the-art predictors such as Social-LSTM, Social-Attention, CIDNN, and etc. Moreover, the ablation tests show that by using the MLPs and GRUs, the ADE and FDE of the model are lower than the STGAT and Social-GAN, further proving the benefits of these new adding modules to the predictor.

The Raft of the Understandability
Authors: Tiwari Abhishek
Published: December 2024

Computer science is full of complex hard-to-understand algorithms. Understandability of an algorithm - ability to explain an algorithm in simple terms - is generally under appreciated. Often poor understandability of an algorithm has a direct impact on practical real-world applications. In my opinion, if we can’t develop intuitions about algorithm it will be very difficult to implement or extend the algorithm for real-world use cases.

Published: December 2024

Introduction Suicide is one of the major causes of death in Nepal. This study examines trends in suicide methods in Kathmandu, Nepal. The study aims to understand suicidal method changes over time and guide effective prevention strategies.
MethodsThis study is descriptive study of autopsy data from the Department of Forensic Medicine at Maharajgunj Medical Campus, Kathmandu from January 2013 to December 2022. Linear regression analyzed changes in suicide rates by gender and method over time. Chi-square tests assessed monthly frequency deviations. Data was stratified by age groups and sex to identify any potential correlations between these variables and the methods of suicide used.
ResultsAmong 2,513 males suicide, the most common method was hanging accounting for 1,633 (64.98%) cases, followed by self-poisoning at 806(32.07%) cases, with falls and self-immolation each at 1.31%. For 1,905 females suicide, hanging remained the most prevalent method with 1,215 (63.77%) cases, followed by self-poisoning at 622 (32.65%) cases, with falls (0.57%) and self-immolation (2.78%) being less common. The mean age for male suicides was 37.15(SD=15.83), while for females it was 30.94 (SD=14.20), indicating a difference of 6.21 years. Suicide rates peaked in summer (July-August) with 450 cases and dropped in winter (December-February) at 309 cases.
ConclusionHanging was the most common method of suicide across all age groups, though its prevalence declined with age. In contrast, self-poisoning became more common as age increased. The study depicted that females tend to commit suicide at relatively younger age than males. Significant seasonal variations in suicide rates were observed.

Published: December 2024

Data on seasonal and long-term dynamics of hydrophysical characteristics in the water area of Lake Manzheroksky (Altai Republic) after dredging in 2017–2018 are presented. The expedition studies were conducted during the ice age in April 2021, as well as the summer warming of the lake in July 2021 and 2023. The spectral index of light attenuation in the range of 400–800 nm, the relative transparency of water over a white disk, the velocity of water movement in surface and bottom horizons, as well as temperature stratification are studied. It was found that the discovered bottom groundwater sources contributed to the erosion and dissolution of the not completely removed silt layer, which determined high values of the spectral index of light attenuation and low relative transparency of the water. The research results in July 2023 showed significant changes in hydrophysical characteristics compared to 2021, indicating an improvement in the ecological condition of the lake in a long-term aspect for the period from 2018 to 2023.

A comparison of spring and summer data on the dynamics of the spectral index of light attenuation at different depths for Lake Manzheroksky with other freshwater low-flow lakes showed that this hydro-optical parameter for the studied lake is maximum during the ice age, while for other lakes its minimum is noted in this phase of the annual limnic cycle.

Este fenómeno se observa en la medicina, aunque cada especialidad enfrenta retos distintos. Objetivo: Determinar la presencia de desgaste ocupacional en docentes y residentes de los programas quirúrgicos en una universidad pública y las principales características del entorno académico y asistencial relacionadas. Metodología: Estudio descriptivo de corte transversal realizado entre agosto y noviembre de 2021. Participaron 36 profesores y 48 residentes de programas quirúrgicos de la Universidad del Valle en Cali, Colombia. La encuesta contenía información sociodemográfica, hábitos, descripción de entornos y las escalas MBI-HSS, PHQ-9 y GAD-7. Resultados: No se encontró presencia de burnout entre los profesores, 32% de los residentes cumplían criterios para burnout. Al realizar la discriminación por subescalas se identificó presencia alta y moderada de agotamiento emocional tanto en docentes como en residentes, altos niveles de despersonalización en residentes, inversamente proporcional a los niveles de realización personal. 28% de los docentes manifestaba algún nivel de ansiedad y 31% diferentes niveles de depresión. En los residentes 84% presentaba algún nivel de ansiedad y 59% diferentes niveles de depresión. Entre los factores del entorno académico asistencial relacionados al agotamiento emocional se encuentran, pasar más de 60 horas mensuales en el hospital, un alto número de turnos y pacientes por turno, turnos nocturnos y menos tiempo de descanso, hallazgos que coinciden con la subescala de despersonalización. Conclusiones: La presencia de burnout se relaciona con síntomas depresivos y ansiosos. Más de un tercio de la muestra de profesores y residentes presentaba depresión y ansiedad, siendo más frecuente en cirujanos en formación. Los estudiantes de posgrados quirúrgicos muestran una alta presencia de síndrome de desgaste ocupacional, con significativo agotamiento emocional, despersonalización y baja realización personal, a diferencia de sus docentes, quienes evidencian agotamiento emocional, ansiedad y depresión, pero no desgaste ocupacional.

The subsurface is perhaps the most important geological layer of the earth’s crust as it contains many natural resources. Additionally, through the study of rocks and unconsolidated sediment accumulations at or near the surface, soil scientist or geologist has discovered much about the earth’s history and the behaviour of its dynamic landforms (Neal, 2004). For the geologist and engineering geologist, the subsurface are the underlying structures, spatial distribution of rock units, structures such as faults, folds and intrusive rocks and the depth of investigation may vary. While for the soil scientist, the subsurface are typical soil horizons and layers of classification up to bedrock (Agriculture handbook, 1999). The shallow subsurface has become a major focus for geoscience research nowadays especially in developing countries as it is closely related to natural resources and humans. As human population increases and developing countries become more industrialised, the subsurface structures become important to study due to its geological behaviour that can pose hazards to human and sometimes help engineers in designing construction foundation and also in archaeological application especially in detecting buried objects.

This article is the first attempt to document the presence of the giant gouramy, Osphronemus septemfasciatus, from Batang Kanowit, Sarawak, Malaysia. The weight of the specimen was 20.5kg, and the estimated standard and total length was 724mm and 872mm respectively. This appears to be the largest individual of the species recorded. This article also highlighted the importance of Batang Kanowit as a fishing ground for the local communities living along the river. Existing and potential threats to aquatic life in Batang Kanowit are discussed and conservation significance of the river is emphasised.

Archaeological excavations were carried out Gua Tupak, Bau, Sarawak by a research team from the Centre for Global Archaeological Research, Universiti Sains Malaysia, Penang and the Sarawak Museum Department, Kuching over a period of three weeks in February and March 2008. These excavations formed the basis of the lead author’s postgraduate study and a preliminary report on the excavations had been published (Gani et al., 2009). Briefly, the excavations yielded various types of artefacts such as shell remains, animal bones, earthenwares, stonewares and stone artefacts (Fig. 1). This article, however, discusses only the classification and the distributions of earthenware sherds excavated from Gua Tupak.

Between June and November of 1947, Edmund R. Leach, an English social anthropologist prepared his report on the prospects of social science research in Sarawak. He did not think much of the available literature on Sarawak as he knew them and in fact lamented that existing literature of the time, though abundant, “give a distorted emphasis to the more exotic aspects of Sarawak”. As he expressed it in the report, his viewpoint differed somewhat from that of ethnologists of the first of two decades of last century. If ethnology is defined also as life histories of groups, then one is regularly beset with problems because as stories spread in oral history from respondent to respondent, often spanning generations, an overarching distortion may occur although without a conscious attempt to lie or to mislead. Quite often, too, possessed by conviction so potent that they tend to embellish the story that they present here and there, yet a belief so zealously guarded that they believe their own embellishments in the end just to maintain group solidarity. Something if repeated very often has the force of truth thereafter. One can of course empathise with Leach’s academic disconcert under such circumstances.

Background: Oxidative stress is an imbalance between the production and clearance of toxic free radicals known as reactive oxygen species (ROS). It is associated with hemolysis, a hallmark of SCD. SCD has long been recognized as an inflammatory condition and oxidative stress play important role in pathophysiology of SCA. Imbalance between production and elimination of reactive oxygen species (ROS) damages cell structures, including lipids, membranes, proteins and nucleic acids resulting in cell death or altered cell function.
Aim: The aim of this study was to measure the serum level of Glutathione peroxidase,
Malonaldehyde and Selenium in SCA (HbSS) in their steady state, AA (Healthy adult) and AS (sickle cell carriers)
Methods: This is a cross- sectional study. A total of one hundred and fifty aged matched participants were recruited for this study.50 SCA subjects with sickle cell anemia (SS). Glutathione peroxidase and Malonyaldehyde were measured using turbidometry and colorimetric methods respectively while Selenium was analysed using Atomic Absorption Spectrophotometry (AAS)
 Results: The result of analysis of variance (ANOVA) showed that the mean serum level of MDA concentration (2.97±0.29) was higher in the SS group and was statistically significant (p< 0.05).  MDA concentration was lower in the AS group. In the post hoc analysis MDA was statistically significant between SS vs AS and AA vs AA. The glutathione peroxidase activity was significantly lower in the SS group (0.85±0.12) compare with the mean values obtained in the AA and AS group. The GPx activity among the three groups was statistically significant while the post hoc analysis among the three groups showed statistical difference and was significant (p < 0.005) The Selenium levels in the SS group is lower compared with the values observed between the AA and AS group. The Se levels in the SS group was statistically lower (5.73±1.34) (p < 0.05) and showed significant difference. The comparison study between AS vs SS and AA vs AA were statistically significant.
Conclusion: The decrease in selenium level potentiates low and weakened antioxidant activity and capacity which also is a reflection of low level of glutathione peroxidase observed which is supposed to attack free radicals to prevent oxidative stress. The findings from this study are in tandem with other researches suggesting that the pathophysiology of sickle cell disease is associated with oxidative stress
