PERFORMANCE OF THE LICENSURE EXAMINATION FOR TEACHERS: BASIS FOR AN INTERVENTION PLAN []


ABSTRACT The study aimed to analyze the results of the Licensure Examination for Teachers (LET) takers of Southern de Oro Philippines College (SPC) during March, June, and October 2022 examination for both Bachelor of Elementary Education (BEED) and Bachelor of Secondary Education (BSED). Specifically, the study aimed to determine the profile of the LET takers in terms of degree program; to find out the performance of the takers in the areas tested in the LET such as general education courses, professional education courses, and major subject for the BSED takers; to determine the overall performance of the school and come up with an intervention program to enhance the performance of the school in the LET. The study employed the descriptive design with documentary analysis and frequency counts and percentage to organize, analyze, and interpret the LET results. Results have revealed that there are more BEED LET takers in the three consecutive examinations yet the BEED examinees did not reach the PRC standard both in the general education and professional education courses. In contrast the BSED takers passed both in the general education and professional courses however, their performance in the major subject was far below against the PRC standard. Thus the academic community may consider increase their admission and retention policies as to admit and retain only the most qualified students. In addition, enhancement and intensive review program may be undertaken specifically in the general education and major subject area to prepare the graduates for the licensure examination.

Estimating the effect of screen time on children’s obesity using a structural model in South Korea []


This research proposes a theoretical framework to investigate the relationship between children's screen time exposure and their obesity as a resource allocation problem for their mothers, using survey data on the elementary school children of South Korea. The study jointly estimates a model of the mother's decision on the level of screen time for her child, the quality of nutrition, the level of labor supply for the mother, the health production function for the child's obesity, and the wage equation. A structural approach is used to model the underlying dynamics and capture the accurate causal relationship. In this approach, the mother's labor supply, time spent at home, and the children's decisions on screen time are all modeled together. This study found that an additional hour of screen time per day is associated with a 1.7 percentage point increase in the obesity rate. This result is slightly lower than the results of a previous study that was conducted on American children. This study contributes to the literature on the impact of screen time on obesity in children. It is the first study to model the screen time of children as the optimized behavior derived from the mother's labor-leisure choice model in South Korea.

On Utilization of Queueing model to customer management in a banking system []


ABSTRACT The presence of queues in banks, Specifically on Mondays and Fridays has led to the application of queuing theory in the banking sector. Queuing theory, which deals with the mathematical study of waiting lines, is well- suited for analyzing the queue and waiting line where customer have to wait for service. This research aims to determine the average time customers spend in queues and the actual time taken for service, with a focus on understanding the impact of time wastage and associated costs. To analyze the queuing model we employed the Markovian birth and death process and specifically applied the multiple servers, single queue (M/M/S) queuing model to analyze the data collected by observation from a bank from the results obtained, the arrival rate is 0.1207 and the service rate is 0.156, the probability that the servers are idle is 0.44 which shows that the servers will be 44% idle and 56% busy, the expected number in the waiting line is 0.1361,the expected number in the system is 0.9098. The expected waiting time in the queue is 1.276 and the expected total time lost waiting time in the queue is 1.276 and the expected total time lost waiting in one day is 3.2664hpurs, the average cost per day for waiting is N65.328 Naira and from the calculation of the comparing solution, the average cost per day from waiting Is N7.966 naira which means that there had been a saving in the expected cost of N65.328 – N7.966 = N57.362. This means that with three servers , the average cost from waiting is reduced. Hence we concluded that the aim and objectives of this paper was achieved.

Obesity is a popular health problem in the world, characterized by metabolic disorder such as Arteriosclerosis, Hyperlipidemia, Type 2 Diabetes mellitus and cardiovascular disease. This study is carried out to determine the effect of Tetracarpidium conophorum nut extract on serum lipid profile of Monosodium Glutamate induced Obesity in rats. Twenty five (25) rats, 15 females and 10 males were obtained from the animal house of the Department of Biochemistry, University of Calabar. The animals were divided and cohabited in five well ventilated cages in the ratio of 3:2 females to males respectively. Obesity was induced in the pups by intravenous administration 4mg/kg body weight of MSG on day 2, 4, 6, 8 and 10. The animals were confirmed Obese using their BMI after 12 weeks. The result of the analysis shows that there was no significant changes (P>0.05) in the lipid profile of the Obese animals (Obsc) relative to the normal (NC). Equally the Obsc group did not show any significant (P<0.05) change relative to the Obc. However, TC, HDL-C, LDL-C decreases and VLDL-C, HDL: TC and LDL: HDL ratios of Obsc increases relative to Obsc group, also the changes were insignificant (P<0.05) upon treatment with the different fractions of the Tetracarpidium conophorum nuts, though EWE treated group shows decrease in total Cholesterol, Triglycerols, LDL-C and VLDL-C while HDL-C decrease relative to Obsc. This Study shows that Tetracarpidium Conophorum have the ability to down regulate Serum lipids.

This study aims to find the effects of human capital variables on the economic growth of Nepal based on time series data from 1981 to 2022. The study adopted an analytical research design. The presence or absence of stationary data was assessed using the Augmented Dickey-Fuller (ADF) test and the overall finding was analyzed using the ARDL technique. The long-run relationship among variables was confirmed through the result of the bound test. The results revealed that human capital significantly influences economic growth of Nepal. Based on the analysis carried out it was concluded that gross fixed capital formation positively but insignificantly impacted on the growth in GDP at 5% level of significance. Expenditure on education has a negative and insignificant effect on economic growth, while expenditure on health has significant but negative effect on economic growth of Nepal. Increased private sector investment, involvement in the areas of health and education could accelerate Nepal's development of its human capital.

THE EFFECT OF STRATEGIC DIRECTION AND LEADING CHANGE ON PERFORMANCE OF LAND ADMINISTRATION IN KENYA: A CASE STUDY OF THE NATIONAL LAND COMMISSION AND MINISTRY OF LANDS, HOUSING AND URBAN DEVELOPMENT []


Kenya's land administration system is costly, undemocratic, bureaucratic, and prone to abuse, resulting in injustices and excessive delays in land administration. Forgery, missing documentation, land grabbing, unlawful allocation, and duplicate land registration are only a few of the difficulties that have tarnished the country's land sector. The current scenario in land administration processes and procedures needs strategic leadership initiatives. The study's overarching goal was to investigate the effect of strategic direction and leading change on performance of land administration in Kenya. The research was founded on Strategic Leadership Theory and supplemented by Path-Goal Leadership Theory and Resource-Based View Theory. A descriptive research approach was used for the investigation. The National Land Commission and the Ministry of Land, Housing, and Urban Development were the study's units of analysis. The clientele and employees of these two organizations served as the units of observation. The survey's target population was two thousand and one (2001), and the overall sample size was 96 respondents chosen at random for the study. The research relied on quantitative data obtained using a questionnaire designed to fit the study's aims. The questionnaire responses were tabulated, coded, and processed on a computer using the Statistical Package for Social Science (SPSS) version 25 programme, which is programmed to analyze quantifiable data using descriptive and inferential statistics such as frequency, mean, correlation analysis, and regression analysis. The study's findings revealed a strong, positive, and substantial association between strategic direction and leading change on land administration performance in Kenya. Furthermore, the research findings revealed 70.6% of the differences in land administration performance in Kenya. The research discovered that the predictor variables had a significant positive effect on land administration performance in Kenya. As a result, the data indicate that there is a significant relationship between strategic direction and leading change on land administration performance in Kenya. Strategic direction and leading change have substantial relationships with important measures of land administration performance in Kenya, such as cost reduction, organizational effectiveness, and efficiency in service delivery, land registration, valuation, and land subdivision.

Mandatory DNA testing for newborns in Namibia: a complex personal security challenge []


This article explores the implications of the anticipated mandatory DNA testing for newborns in Namibia, focusing on the complex personal security challenges it presents. While DNA testing can offer valuable insights into a child's genetic heritage and potential health risks, it raises important personal security issues. This study employed a qualitative research approach. Participants were interviewed, focusing on their perspectives regarding the implications of mandatory DNA testing on personal security in Namibia. In-depth interviews were conducted with the participants to elicit their views on the research objective. The responses were transcribed and analysed thematically. The study revealed that the policy could lead to increased violence, particularly due to exposure to infidelity. It could disproportionately affect women and potentially exacerbate gender inequalities. Legal and ethical challenges were also highlighted, particularly concerning individual rights and consent. Gender disparities emerged as a significant concern, suggesting that the policy might not deter cheating but rather prompt women to seek alternative means to avoid shame and blame. To address these concerns, the study recommends a comprehensive public education campaign, strengthening legal and ethical frameworks, adopting a gender-sensitive approach, providing mental health support services, and ongoing evaluation of the policy's impact. These recommendations aim to balance the benefits and potential drawbacks of mandatory DNA testing in Namibia and ensure personal security for all citizens.

Is childhood short stature effect on thyroid and kidney functions []


Background: Growth process is a combination of several factors, including genetic, environmental, nutritional, metabolic and health problems including thyroid and renal diseases, and this process depends mainly on age and gender. A set of standard data ranges (head circumference, height, and weight) are determined at each stage of natural growth, and if the growth pattern less than these ranges, this leads to short stature and growth failure. Methods: Serum triiodothyronine (T3) , thyroxine (T4) and thyroid stimulating hormone (TSH) concentrations were assayed by using the Japanese TOSHO AIA-360 Automated Immunoassay Analyzer, also glucose, creatinine and urea were estimated by using BIOLABO kits (France) in 30 healthy children as control group and 60 patients with short stature , age range (5 - 14) years. Purpose: This study aimed to evaluate some biochemical parameters related to thyroid and kidney to determine the extent to which the parameters are affected by this disease, which reflect function imbalance of the relevant organs, and to use it as a diagnostic tool that helps in the early treatment and follow-up of the short stature state. Results: The results showed that all biochemical parameters were studied representing by the concentrations of T3, T4, TSH, glucose urea and creatinine did not show any significant difference in children with short stature compared to the control group. However, TSH, creatinine and urea showed an increase by (31.8 %,),( 6.1 %) and (2.7 %) respectively, while a decrease in the concentration of T3 was observed by (9.4%) in children with short stature compared to control group. Conclusions: It appears that, the condition of short stature in children does not have a clear effect on kidney and thyroid functions, as well as regulation mechanism of thyroid hormones secretion by TSH.

COMPARISON OF THE IMPLEMENTATION OF UPPER BASIC EDUCATION CURRICULUM BETWEEN PRIVATE AND PUBLIC SCHOOLS IN NIGERIA []


This study compared the implementation of upper basic education curriculum between private and public schools in Nigeria. The study adopted a cross sectional survey research design. three research questions and three null hypotheses guided the study. A sample of 1134 respondents comprising 954 teachers and 180 supervisors from a population of 145,783 teachers and 19,466 supervisors were used for the study. Multistage sampling technique was adopted for the study. Questionnaire on the Implementation of Upper Basic Education Curriculum (QIUBEC) was used for data collection. The instrument was validated by three experts. A reliability coefficient of 0.98 for the QIBEC was obtained using Cronbach Alhpa. Mean, percentage and standard deviation was used to answer the research questions while t-test was used to test the null hypotheses at 0.05 level of significance. The findings revealed that there was significant difference in teachers’ coverage of scheme of work (p = 0.000 < 0.05), use of other curriculum besides the 9-3-4 curriculum (p = 0.050 = 0.05), However, the study found no significant difference in the mean teachers’ use of pedagogical knowledge for the implementation of Upper Basic Education Curriculum in private and public schools (p=0.123 > 0.05). Based on the findings, the following recommendations were made among others: Curricula not approved by the Federal Government of Nigeria or other authorities saddled with the responsibilities for curricula approval should not be used at the upper basic education level; teachers should choose pedagogies that give all students in the classroom equal learning opportunities to reach their full potentials, teachers’ human capacity development is advantageous so both private and public schools must commit human and fiscal resources to maintain skilled and knowledgeable staff.

La déperdition scolaire à l’école marocain []


Dans cet article nous abordons la problématique de la déperdition scolaire au Maroc, mettant en évidence les efforts du gouvernement pour lutter contre ce phénomène, en soulignant l'importance de l'éducation des enfants marocains pour le ministère de l'Éducation Nationale et en constatant également des problèmes persistants dans le système éducatif. Malgré diverses réformes, le système éducatif marocain montre des signes de défaillance. Le classement international des écoliers marocains a chuté, et le pays dépense beaucoup pour l'éducation sans obtenir des résultats satisfaisants. Plusieurs facteurs sont responsables de la déperdition scolaire, notamment le handicap financier des parents, l'inadéquation des programmes éducatifs et les problèmes liés aux enseignants et à l'infrastructure scolaire. Le gouvernement marocain a mis en place plusieurs initiatives pour lutter contre ce fléau, notamment le programme "un million de cartables," le programme Tayssir, le programme Massar, les cantines scolaires, les internats, et les transports scolaires. Nous mettons en évidence les défis du système éducatif marocain et les mesures entreprises pour réduire la déperdition scolaire et améliorer l'accès à l'éducation.

LITHOSTRATIGRAPHIC STUDY OF THE MPIOKA GROUP AND THE INKISI GROUP IN THE NTADI AND NDUMBA/KONGO CENTRAL AREA []


The lithological sequence of the upper part of the Mpioka Group, essentially pelitico -arenaceous, includes an alternation of sandstones and argillites. The hues generally observed in these formations are salmon and brownish red, green, wine red at the top, the major constituents of these rocks are quartz, feldspars, mica, opaque minerals and lithic debris. Quartz grains are coarse and cracked. The sandstone beds result from rapid sedimentation of medium-density debris flows; on the other hand, the argillite beds are deposits resulting from the suspensions of low density turbidity currents. The succession of green and red coloring of the shales testifies that during the deposit of the Mpioka Group , we pass from oxidizing conditions to reducing ones and to a return to initial conditions. The origin of the sediments is established on the basis of detrital grains such as quartz, feldspars, micas, zircon and rock fragments.

Inventaire de la faune mammalienne dans les galeries forestières des rivières du haut bassin du fleuve Sénégal et environ (Mali) []


La faune sauvage de mammifères des galeries forestières des rivières Baoulé, Bakoye, Bafing, Falémé et du Lac Magui du haut bassin du fleuve Sénégal est agressée par la forte pression des activités anthropiques. La présente étude est initiée dans le but d’inventorier les espèces de mammifères présentes dans ces galeries forestières. Elle s’est déroulée de 2019 à 2020 en utilisant la méthode d’observation directe pédestre à l’aide de jumelles. Les observations ont été réalisées à l’aube et au crépuscule dans des unités spatiales d’inventaire de 5 km de long sur 2 km large dans chaque site retenu. Les données collectées ont permis de déterminer les indices de diversité, les fréquences et les menaces sur la survie des espèces. Au total, 19 espèces ont été recensées reparties entre 19 genres et 13 familles. La galerie forestière de la rivière Falémé a présenté 14 espèces, suivie de celles des rivières Bakoye (7 espèces), Baoulé (6 espèces), Bafing (5 espèces) puis du lac Magui (4 espèces). Les espèces constantes étaient représentées par Erythrocebus patas, Xerus erythropus et Helioscirus gambianus avec une fréquence de 80% chacune et par Rattus rattus à 60%. Les espèces accessoires étaient composées de Tragelaphus scriptus, Cercopithecus aethiops, Erinaceus albiventris, Felis sylvestris et Hippopotamus amphibius avec une fréquence de 40% chacune et les autres espèces étaient accidentelles. Les valeurs de l’indice de diversité (3,50) et d’équitabilité (0,82) ont montré que les peuplements de mammifères étaient équilibrés dans l’ensemble. Les espèces ne présentaient pas une différence d’abondance importante les unes par rapport aux autres. Les activités anthropiques identifiées étaient l’extension des champs, l’orpaillage, la déforestation et le braconnage. Ces résultats serviront aux décideurs pour la mise en place de plans de gestion communautaires des ressources naturelles.

PERFORMANCE IMPROVEMENT OF PROTON EXCHANGE MEMBRANE FUEL CELL (PEMFC) IN VEHICLE THROUGH GAS FLOW CHANNEL (GFC) USING CFD SIMULATION []


This research presents the impacts of Gas flow channel designs on the performance of proton exchange membrane fuel cells were investigated using a three-dimensional computational fluid dynamics (CFD) model in ANSYS 2020 R1 FLUENT. The model was created with different gas flow channel arrangements of proton exchange membrane (PEM) fuel cells with straight, Serpentine, combined and with blockage flow channels. This study involves the CFD simulations of PEMFC under non-isothermal conditions; the simulation is run on 353 K and 3 atm to investigate the performance of fuel cells. The results show that gas flow channel design is affecting system performance in PEM fuel cells. At V=0.6V the current density value of full blockage of the flow channels with 2 and 3 blocks along the serpentine channels are 2.231 A/cm2 and 2.311 A/cm2. The experimental current density value at this voltage value is 1.391A/cm2. The simulation results here give good agreement with experimental results data reported in the literature and the newly designed model. This gives high confidence for the results to determine the effectiveness of the flow field design in the Proton Exchange member fuel cell (PEMFC). At 0.6V the current density value increases from 2.338 A/cm2 (serpentine) to 2.654 A/cm2 (Biometric FC). The performance of PEMFCs with the Biometric flow channel is superior to that of other PEMFCs. This led us to a better design of the gas flow channel of PEMFC and improved hydrogen fuel cell vehicle performance.

EARLY PARENTHOOD PSYCHOLOGICAL SUPPORT AND PSYCHODIAGNOSTICS HEALING AMONG TEENAGERS AFTER GIVING BIRTH IN RWANDA []


Abstract It is evident that early parenthood has significant psychological impacts on teenagers in Mahama refugee camp, located in Kirehe District, Eastern Province, Rwanda. This study identified the contributing factors of early parenthood on psycho-diagnostics, the most common psychopathologies among teenage mothers, screening tools used to assess psychopathologies among teenage mothers, and the kind and outcomes of psychological support given to the teenage mothers in the camp. It was a descriptive study using both qualitative and quantitative methods. The study respondent was selected purposive and convenient sampling techniques and included 92 teenage mothers, three staff member in Mahama Refugee Camp. The respondents were aged between 16 to 19 years old with the mean age of 18.84 (SD = 0.81). Findings of this study shows that early parenthood has significant psychological impacts on teenagers, with many respondents reporting feelings of shame, worthlessness, sadness, isolation, self-blame, and fear. Contributing factors to early parenthood were identified as lack of knowledge and limited self-efficacy regarding sexual and reproductive health decisions, poverty, and premature independence. While anxiety is a common issue (22.8%) among teenage mothers, only two respondent showed high level of depression and none showed PTSD. The psychological support provided to teenage mothers, including individual and group psychotherapies as well as social supports such as tangible materials and vocational training was found to have positive outcomes. These include decreased symptoms of psychopathologies, improved coping skills, enhanced self-understanding, strengthened family relationships, increased self-esteem, and peer support. This study underscored the psychological challenges faced by teenage mothers and the need for targeted interventions to support this vulnerable group. The findings also suggest that while current psychological support strategies have positive outcomes, there is a need for more specific screening tools to identify psychopathologies among teenage mothers in Mahama refugee camp.

Highly sensitive micro-structured Fiber Bragg Grating-based temperature sensor enhanced by Electroplated Cu-Ni layer []


The temperature FBG probe head inscribed with eight micro-structured at 30 mW laser pulse power and embedded with bi-mettalic temperature sensitive films (nickel and copper) are proposed. The copper rod (anode) is connected to the positive terminal of the supply, and the conductive fiber (cathode) is connected to the negative terminal. Both electrodes are immersed in the copper sulfate (CuSO4) plating solution. During the electroplating process, copper is oxidized at the anode to Cu2+ by losing two electrons. The Cu2+ associates with the anion SO42- in the solution to form copper sulfate. At the cathode, the Cu2+ is reduced to metallic copper by gaining two electrons. Thermal expansion between silica and metallic elements is integrated with micro- laser grooves and temperature trasducer(Cu-Ni) layer. Thus, sensitivity of bi-metal coated FBGs improved significantly due difference of Young’s modulus. Temperature and strain showed a very good agreement during characterization, with temperature sensitivity being 18.8 pm/oC between 20-300 oC temperature range. This is a 86% more sensitive compared with a reported bare FBG sensor (10.1 pm/oC).
