Impact of Outcome-Based Education (OBE) on Learners' Performance in Business Courses

Purpose: The study aims to introduce a new format of education called outcome-based education (OBE), its importance, and its impact on learners' performance in business courses.   Theoretical framework: Outcome-based education (OBE) ensures that new learners enter the classroom exceptionally prepared with the skills, mindsets, and values required to grow into successful adults after they leave the educational system. Outcome-based education (OBE) is a teaching approach that concentrates on how novices will perform in the future and how to use knowledge to accomplish objectives after instruction.   Methodology: The qualitative method was chosen as the content is theoretical, for outcome-based education has been compared with conventional education. This study begins by tracing the evolution of outcome-based education (OBE) and introducing crucial implementation criteria. Following the discussion of impacts, it is covered how the concept of repercussions necessitates a paradigm shift in evaluation and evaluation methodologies. The study then goes through the crucial effects of implementing the exercise and methods for rating and evaluating learners' success in business school. These repercussions are closely related to discussing the four critical philosophies of outcome-based education (OBE). Based on that, results are drawn.   Results and conclusion: It is confirmed that OBE develops a learner's Fundamental knowledge, problem-solving skills, research skills, technical skills, social skills, ethical values, communication skills, project management skills, and life-long skills that have a significant impact on one's career.   Originality/Value: Outcome-based education (OBE), which directs learners in building their professional careers and increases their knowledge and creativity, is the newest education trend. In the context of their workplace, OBE might support their healthy development. The National Board of Accreditation (NBA) requires the application of the appropriate evaluation strategies for learners to acquire the skills indicated for outcome-based education. Outcome-based education (OBE) is attractive because it can improve coaching, the educational system, and learners' performance, which primarily rely on evaluating graduates' skills. Through this process, the learner will learn how to bridge the gap between tutoring and results-based mastering techniques. No one in South Asia didn't undertake any research on the subject; as a result, the fresh information would help to enhance management, encourage innovation, and boost performance.   Contribution: The suggested methodological model, one of the most fundamental advances in business education, would improve scientific capabilities in the training process at the business school and permit a widespread incidence in the academic environment

Leiomyosarcoma presenting as a spontaneously ruptured renal tumor-case report

BACKGROUND: Ruptured renal neoplasms can be a catastrophic clinical presentation. Angiomyolipoma is the commonest renal tumor which presents in this fashion. Renal sarcomas are rare renal neoplasms. Renal leiomyosarcomas are the most common histological subtype of renal sarcomas, accounting for approximately 50–60% of the reported cases. These tumors are usually peripherally located and appear to arise from either the renal capsule or smooth muscle tissue in the renal pelvic wall. CASE PRESENTATION: A 70 years old male, with hypertension and ischemic disease, developed acute left flank pain. The general physician evaluated this using ultrasound, which showed a solid left renal mass. Two weeks later, he presented in the emergency room in a state of shock with a palpable flank mass. CT scan of the abdomen showed a large heterogeneous mass lesion in the left perinephric space with minimal post contrast enhancement. Per-operatively, large retroperitoneal hematoma was found within Gerota's fascia along with spleen plastered to the upper limit of hematoma. Nephrectomy and splenectomy were performed. Postoperative course was uneventful and patient was discharged on the 10(th )post-operative day. Histopathological evaluation of the specimen showed high-grade leiomyosarcoma CONCLUSIONS: Spontaneous rupture of renal neoplasm is a rare clinical presentation. Angiomyolipoma is the commonest cause of spontaneous rupture of the kidney. Presentation of a leimyosarcoma as a ruptured renal neoplasm has not been previously reported in the English literature

Novel insights on intake of fish and prevention of sarcopenia: All reasons for an adequate consumption

Sarcopenia is defined as a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength and it is diagnosed by measurements of muscle mass, muscle strength, and physical performance. Sarcopenia affects quality of life and is associated with several adverse health effects. Muscle decline is aggravated by a sedentary lifestyle and can be prevented through proper nutrition, together with adequate physical activity. Fish contains biologically active compounds, such as omega-3 polyunsaturated fatty acids, proteins, vitamin D, magnesium, and carnitine, which are able to intervene positively on muscle metabolism. This narrative literature review was performed to evaluate evidence regarding the actual benefit of fish consumption in the prevention of sarcopenia and the positive action on the muscle mass of the biological compounds present in fish. The results demonstrated that fish consumption has a protective and anti-inflammatory function on skeletal muscle and that its biologically active compounds help to maintain good muscle performance, preventing sarcopenia. Considering the nutritional and health benefits, elderly with sarcopenia should consume at least three servings per week of fish in order to have a minimum intake of 4–4.59 g daily of omega 3, and reaching the 50% RDA in Vitamin E and D. High biological value of proteins in 150 g of fish and its high available magnesium (20% of RDA in 150 g of fish) are an added value that could suggest fish as a “functional food” in order to prevent and treat sarcopenia

Antimicrobial potential of alkaloids and flavonoids extracted from Tamarix aphylla leaves against common human pathogenic bacteria

Background: Alkaloids and flavonoids are secondary metabolites extracted from different medicinal plants. Tamarix aphylla a traditionally valuable medicinal plant; was used for the extraction of alkaloids and flavonoids in order to evaluate their antibacterial activity.Methodology: The leaves of the plant were collected from district Kohat, Pakistan, and their alkaloids and flavonoids were extracted with ethanol and methanol, respectively. Four bacteria i.e. Gram positive (Staphylococcus aureus) and Gram negative (Escherichia coli, Salmonella typhi and Pseudomonas aeruginosa) were selected for the biological screening of these phyto-constituents.Results: The concentration of alkaloids was found to be more in the leaves of Tamarix aphylla than flavonoids. The extracted phytochemicals showed varied inhibition zones against tested bacterial isolates. Alkaloids showed highest inhibitory activity against Staphylococcus aureus (14±0.6 mm) followed by Pseudomonas aeruginosa (13±0.7 mm). Conversely, flavonoids showed the highest inhibitory affect against Salmonella typhi (17±0.7 mm) followed by Staphylococcus aureus (14±0.7 mm). However, both extracts showed the lowest inhibitory effects against Escherichia coli.Conclusions: It was concluded that the alkaloids and flavonoids from Tamarix aphylla leaves have antimicrobial potential against common human bacterial pathogens. However, flavonoids were found to be more active phytochemical against tested bacterial strains as compared to alkaloids.Keywords: Kohat; Medicinal plants; Phytochemical screening; In-vitro activity; Bacterial strains

Thermoelectric Properties of Oxide Semiconductors

In this chapter, we have explored the potential of oxide semiconductors for thermoelectric power generation. Various oxides (Cu2InO4, CuAlO2, and Zn2GeO4) were grown on Si substrate by thermal evaporation method using tube furnace. After the growth, a representative sample of each oxide was cut into pieces and was annealed at various temperatures from 600 to 800°C in oxygen environment for 1 h using a programmable furnace. The structure of all annealed sample was verified by performing X-ray powder diffraction (XRD) measurements. XRD data suggested that all oxide materials show crystalline behavior at annealing temperature 800°C. XRD results further confirmed that crystal structure of investigated samples improved significantly with annealing because the intensity of oxygen-sensitive (0 0 6) plane was found to be increased with annealing temperature. To investigate the thermoelectric properties of annealed samples, Seebeck effect and Hall effect measurements were performed in the temperature range 25–100°C. It was found that the value of Seebeck coefficient and power factor increased as the annealing temperature increases. Zn2GeO4 was found to be a potential thermoelectric material because it has the highest value of Seebeck coefficient and power factor. This highest value is related to the presence of secondary phases in this oxide

Identification of significant E0E0 strength in the 22+→21+2^+_2 \rightarrow 2^+_1 transitions of 58,60,62^{58, 60, 62}Ni

The $E0$ transition strength in the $2^+_2 \rightarrow 2^+_1$ transitions of $^{58,60,62}$Ni have been determined for the first time following a series of measurements at the Australian National University (ANU) and the University of Kentucky (UK). The CAESAR Compton-suppressed HPGe array and the Super-e solenoid at ANU were used to measure the $\delta(E2/M1)$ mixing ratio and internal conversion coefficient of each transition following inelastic proton scattering. Level half-lives, $\delta(E2/M1)$ mixing ratios and $\gamma$-ray branching ratios were measured at UK following inelastic neutron scattering. The new spectroscopic information was used to determine the $E0$ strengths. These are the first $2^+ \rightarrow 2^+$ $E0$ transition strengths measured in nuclei with spherical ground states and the $E0$ component is found to be unexpectedly large; in fact, these are amongst the largest $E0$ transition strengths in medium and heavy nuclei reported to date

Increased isomeric lifetime of hydrogen-like Os-192m

An excited metastable nuclear state of 192 Os in a hydrogen-like charge state has been studied for the first time. It was populated in projectile fragmentation of a 197Au beam on a 9Be target with the UNILAC-SIS accelerators at GSI. Fragmentation products in the region of interest were passed through the fragment separator and injected into the experimental storage ring (ESR). Cooling of the injected beam particles enabled Schottky mass spectrometry to be performed. Analysis shows the lifetime of the state to be considerably longer than that of the neutral ion [τneut=8.5(14) s]; this change is attributed to hindrance of internal conversion in hydrogen-like 192Os. Calculations have been performed to estimate the lifetime, and the result has been compared with that measured experimentally. There is good agreement between the expected [τH−like=13.0(24)s] and measured lifetimes (τrest=15.1+1.5−1.3s) from the internal decay of 192mOs. This provides a test for the reliability of the values obtained from internal conversion coefficient calculations in highly ionized systems and is the first measurement of its kind to be performed using the ESR setup

The E0 transition strength in the 22+ → 21+ transitions of 58,60,62Ni have been determined for the first time following a series of measurements at the Australian National University (ANU) and the University of Kentucky (UK). The CAESAR Compton-suppressed HPGe array and the Super-e solenoid at ANU were used to measure the δ(E2/M1) mixing ratio and internal conversion coefficient of each transition following inelastic proton scattering. Level half-lives, δ(E2/M1) mixing ratios and γ-ray branching ratios were measured at UK following inelastic neutron scattering. The new spectroscopic information was used to determine the E0 strengths. These are the first 2+ → 2+ E0 transition strengths measured in nuclei with spherical ground states and the E0 component is found to be unexpectedly large; in fact, these are amongst the largest E0 transition strengths in medium and heavy nuclei reported to date
