The participants of this study are students, teachers, and school principals. The results of this study show that structured and continuous implementation of cultural values has significantly impacted the academic and non-academic achievement of the schools. In the academic aspect, both schools graduated many students who were accepted by reputable universities in Indonesia, such as the University of Indonesia, the University of Gadjah Mada, the Institute of Technology Bandung, the University of Padjajaran, and the University of Tadulako. Similarly, the schools also experienced high achievement in non-academic aspects such as national and international science Olympics. This study suggests that integrating school cultural values with students' psychological and spiritual needs can be an effective strategy for improving academic and non-academic performance. It is recommended that schools focus on strengthening their cultural values in their education process.

Experience of dental caries among libyan children with type 1 diabetes mellitus: a cross-sectional study

2025-04-30T05:11:54+00:00

Background: Diabetes is often associated with a number of medical and oral complications as a result of the metabolic changes taking place systemically.

Aim: To assess the impact of type1 diabetes mellitus (T1DM) on oral health among a group of Libyan children and compare these findings to matched medically fit children.

Subjects and methods: A comparable cross-sectional study between diabetic and non-diabetic groups of children. A total of 80 children aged between 8 and 15 years with Insulin Dependent Diabetes Mellitus presenting to the pediatric endocrinology clinic of the BMC and Pediatric hospital, Benghazi were age, gender and socioeconomic matched to a control group of 80 children attending for a dental checkup at the dental clinics. Caries experience of all children was recorded using WHO examination criteria and personal data was collected using self-administered questionnaire. The SPSS Inc., Chicago, IL for Windows version 24.0 was used for statistical analysis.

Results: The two groups were matched in term of gender and each of them was composed of 37 (46.3%) males and 43 (53.7%) females. The prevalence of dental caries was higher among non-diabetic subjects (58.8%, 52.5% respectively) compared to diabetic group (38.7%, 41.3% respectively). Whereas children with diabetes mellitus had a higher DMFT score with mean 1.48+2.2 which indicate more carious intensity (p=0.33). More than one third of diabetic children (41.3%) had at least one decayed, missing or filled tooth. Decayed teeth comprised the biggest component of the DMFT and dft scores in the two groups.

Conclusion: The difference in caries experience between the diabetic and non-diabetic children were not statistically significant. A more detailed study may provide more information on the influence of T1DM on the oral health status in this group.

The study examined the migration and remittance on economic growth in Nigeria. The specific objectives were to: ascertain the impact of migration on economic growth in Nigeria and determine the impact of remittance on economic growth in Nigeria. The research design was ex post-facto method. The variables consist of real Gross domestic Product (RGDP), net migration rate (NMG), international migration stock (IMG), diaspora remittance (REM), trade openness (TRADE) and exchange rate (EXCH) for the period of 1990 to 2024 The method of data analysis was divided into three phases namely: pre-estimation, estimation and post-estimation. The method of data analysis was Dynamic ordinary least square (DOLS). The empirical results showed that international migration has 10 percent negative and insignificant impact on economic growth (t-statistics; -0.3335; p-value; 0.7450 > Sig-value: 0.005) and diaspora remittance has positive and significant impact on economic growth (t-statistics; 7.7346; p-value; 0.0000 < Sig-value: 0.005). This study concludes that migration has 10 percentage negative and insignificant impact on economic growth in Nigeria while remittance has 60 percentage positive and significant impact on economic growth in Nigeria. The study concluded that Nigeria government should adopt strategies to stemming international migration by addressing push factors of unemployment, low salaries, limited chances of self-advancement, poor conditions of service, poverty and pull factors such as job opportunities, safety and security, wealth prospects, food security and conflicts, better conditions of service and higher standards of living since they are the root causes of international migration.

Advances in microbial bioreactors: enhancing yield through process intensification

2025-05-03T17:15:03+00:00

Developments in Microbial Bioreactors: Increasing Yield by Intensifying the Process Critical issues in microbial bioreactors, such as low productivity, ineffective substrate conversion, and excessive resource consumption, can be resolved via Process Intensification (PI). Using the SEST paradigm (Structure, Energy, Synergy, Time), this research examines current PI techniques in microbial bioprocessing and assesses their effects on sustainability and yield enhancement. Three key technologies show particular promise: perfusion-based cell cultures (achieving cell densities 3-10 times higher than batch processing), continuous-flow biocatalysis (improving volumetric productivity 3-5 fold), and microbubble-assisted mass transfer (increasing oxygen transfer efficiency by 40-60% while reducing energy requirements). Improved process control, decreased environmental impact, and increased volumetric output are just a few of the measurable advantages that these methods offer. A route towards adaptable, responsive biomanufacturing systems is made possible by the combination of PI with metabolic engineering and digital monitoring technologies. Implementing PI provides a convincing approach to creating high-performance, sustainable microbial bioreactors for next-generation industrial biotechnology, notwithstanding technological and regulatory obstacles.

Addressing the CO2 challenge: the role of carbon capture and sequestration in reinventing climate solutions

2025-06-02T06:24:17+00:00

Climate change is one of the major causes of global warming and its consequent serious, complex and cascading risks are being felt across different sectors and regions of natural and human systems on all continents and across the oceans. Various complementary strategies in relation to adaptation and mitigation processes are being adopted at local, regional, national and global levels for reducing and managing the greenhouse gas emissions and the risks of climate change, thereby assessing their interaction with sustainable development. In order to address this problem, a revolution in energy technology and the transformation of energy systems are needed that includes higher energy efficiency, increased renewable energies and the decarbonisation of fossil fuel-based power generation. ‘Carbon Capture and Sequestration (CCS)’ technology is one such prospective mitigation strategy that allows continuous use of fossil fuels and provides time to make the changeover to other energy sources in a systematic way – so as to achieve the large-scale reductions in atmospheric CO2. The technology involves capture, transport and storage of CO2. Developing appropriate policy instruments and support frameworks focusing on carbon pricing are the need of the moment from policymakers and governments so as to aggressively drive negative emissions projects.

Implementation of Islamic religious education values in building a peaceful life post-conflict at Poso State Senior High Schools

2025-06-05T13:42:19+00:00

This study aims to investigate the implementation of Islamic religious education values in building a peaceful life post-conflict at senior high schools in Poso. This study employed a multiple qualitative case study method. Data were collected through in-depth interviews, field observation, and document analysis. The research subjects are two reputable state senior high schools in the Poso Regency. The participants of this study are students, teachers, and school principals. The results of this study show that the implementation of Islamic values in both schools includes congregational prayers, where non-Muslim students participate by helping to record those who worship. During religious holidays such as the celebration of the Prophet's Birthday, Isra' Mi'raj, and Christmas, students from various religions are not given a holiday, but they celebrate these holidays together. Furthermore, all students from various religions work together to clean places of religious worship and provide assistance to orphanages. The school has integrated religious education values in learning that are in line with the values of Pancasila, namely the values of faith, morals, worship, and other aspects that support the formation of a peaceful life character. All learning materials have supported the formation of character, faith, noble morals, and moderate religious behavior such as tolerance, national commitment, anti-violence, respect for differences, and love for the homeland.

Generation Z perceptions of the problem-based learning approach in science instruction at SMP Negeri 2 Tondano and SMP Santa Rosa de Lima Tondano

2025-06-15T13:29:02+00:00

This study investigates Generation Z students’ perceptions of Problem-Based Learning (PBL) in the context of Science instruction at SMP Negeri 2 Tondano and SMP Katolik St. Rosa de Lima Tondano, Indonesia. Generation Z learners, born between 1997 and 2012, are characterized by strong digital literacy, preference for visual and collaborative activities, and a need for contextualized, meaningful learning experiences. Despite existing research affirming PBL’s effectiveness in promoting critical thinking and intrinsic motivation, limited attention has been given to Generation Z’s own perceptions of PBL—especially within a local Minahasa setting—and to how educators might integrate Christian faith values within a PBL framework. Employing a mixed‐methods, descriptive–quantitative design, data were collected from seven‐item Likert‐scale questionnaires (n = 50), structured interviews, and direct classroom observations. Quantitative analysis reveals that most participants perceive PBL as highly engaging, fostering collaboration, and enhancing conceptual understanding in ecological and biodiversity topics; average scale scores exceeded 80% on key items. Qualitative findings corroborate these results, indicating students’ heightened motivation, increased participation, and appreciation of real‐world scientific inquiry. However, some students reported challenges related to group dynamics, insufficient scaffolding by teachers, and initial unfamiliarity with autonomous problem‐solving. Additionally, respondents valued the integration of Christian principles—such as stewardship of creation, integrity, and communal responsibility—as enriching the PBL experience and reinforcing character development. The study recommends targeted professional development for teachers in PBL facilitation, development of contextually relevant problems linked to local environmental issues, and deliberate incorporation of faith‐based values to align science instruction with students’ cultural and spiritual backgrounds.
