2025-04-29T10:13:55+00:00

This research aims to analyze the role of school cultural values in improving student achievements at senior high schools in Palu City. Schools serve as educational institutions that develop academic abilities and are responsible for shaping students' character through the internalization of positive cultural values. Honesty, discipline, commitment, cooperation, and respect are believed to create a conducive learning environment that supports the learning process. This study employed a qualitative method with a case study approach. Data were collected through in-depth interviews, field observation, and document analysis. The research subjects are two reputable schools which are Senior High School of Al-Azhar and State Islamic Senior of Insan Cendikia Palu. 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.

Impact of migration and remittance on economic growth in Nigeria: dynamic ordinary least square model

2025-05-06T05:32:00+00:00

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.
