An Analysis of Learning Outcomes in Single National Curriculum for Grade Pre-I in Punjab, Pakistan

The present study aims to identify the levels of critical thinking skills in learning outcomes of the single national curriculum (SNC) 2020 for early childhood care and education grade pre-I in Pakistan. The Objectives of the study are supposed; to find out the frequency of learning outcomes designed by adopting different levels of critical thinking skills, to identify balance between learning outcomes designed keeping in view LOTS and HOTS, and to highlight the elements or action verbs being used to make the statements of learning outcomes at different levels of critical thinking skills. Quantitative data analysis approach is deployed to find out the frequency of different levels of critical thinking skills-based learning outcomes in SNC for grad pre-I.  A Stratified type of sampling is used to make decisions about the selection of a single national curriculum for grade pre-I and purposive sampling was adopted to select the learning outcomes of SNC for grade pre-I. The critical Thinking Evaluation Model is implied to evaluate the learning outcomes at different levels of LOTS and HOTS. Findings indicate that LOTS are more focus of curriculum designers. SNC designers for grade pre-I are supposed to prepare students most prominently at the knowledge level, more frequently at the implementation level, and least frequently at self-directed learning level. This research is significant for curriculum designers, syllabus designers, teachers, and teacher trainers to make sure the balance between LOTS and HOTS, and the balance between the learning at each level of critical thinking skills while designing, teaching, and training.  &nbsp

Knowledge, attitude and misconceptions regarding tuberculosis in Pakistani patients

Objective: To assess knowledge of patients with tuberculosis; about their disease and misconceptions regarding TB. Methods: A cross sectional study was conducted at Out-patient clinics of two teaching hospitals (private and public) in Karachi, Pakistan. A questionnaire was filled for the purpose. Results: A total of 170 patients were interviewed, 112 from private and 58 from a public sector hospital. Cough, fever, bloody sputum and chest pain were recognized as the common symptoms of TB. Eleven (7%) patients thought TB was not an infectious disease and 18 (10.6%) did not consider it a preventable disease. Contaminated food was considered the source of infection by 81 (47.6%) and 96 (57%) considered emotional trauma/stress the causative agent of TB. No counseling about preventing spread was received by 81 (50%) patients and 97 (57%) considered separating dishes as an important means of preventing spread. Thirty one (18%) patients would have discontinued their medications following relief of symptoms. Thirty nine (23%) of the respondents thought that TB could lead to infertility and 66 (38.8%) believed that there were reduced chances of getting married following infection. Conclusion: Misconceptions concerning TB are common in Pakistani patients. Lack of knowledge on Tuberculosis is alarming. (JPMA:56:211;2006

Community acquired pneumonia: risk factors associated with mortality in a tertiary care hospitalized patients

OBJECTIVE: To evaluate risk factors associated with mortality in patients hospitalized with CommunityAcquired Pneumonia (CAP) from a developing country. METHODS: An observational study was conducted on adult patients admitted with a diagnosis of CAP from January 2002 to August 2003 at Aga Khan University hospital, Karachi, Pakistan. Clinical records were reviewed for demographic characteristics, clinical and laboratory features, hospital course, and risk factors associated with mortality. RESULTS: A total of 329 patients (187 males) were admitted with CAP. Two-third of patients had underlying co-morbid medical illnesses. Complications developed in 15.7% cases and the overall mortality rate was 11%. Risk factors were identified on initial clinical assessment, laboratory and radiological features and during hospital course. On admission elevated blood urea, new onset of confusion, abnormal liver function test, low serum albumin, cardiomegaly and presence of underlying malignancy were strongly associated with increased mortality. Failure to respond to therapy was associated with a high risk of mortality as depicted by complication during hospital stay (Odds Ratio = 23.3, 95% Confidence Interval = 10.3-52.8), need for mechanical ventilation (OR = 17.1, 95% CI = 7.4-39.8) and need for intensive care unit (OR = 9, 95% CI = 4.2-19.3). CONCLUSIONS: Abnormal liver function test, low albumin and presence of cardiomegaly were more significant mortality risk factors than age, respiratory rate and blood pressure. Elevated blood urea and confusion remain strong risk factors on admission. Failure of response to therapy and onset of complications heralded a high risk of death

The interactive impact of straw mulch and biochar application positively enhanced the growth indexes of maize (Zea mays L.) crop

A two-year experiment was carried out at Shenyang Agricultural University’s research field area in China to evaluate the impact of the combined application of straw mulch (0 and 8 t ha−1) and biochar (0, 4, 12, and 36 t ha−1) on the morphological traits and grain development of rainfed maize during 2018 and 2019. The results showed that straw mulch and different biochar application rates significantly impacted the maize growth index. Compared to non-biochar-treated soils, the introduction of straw mulch improved plant height, stem diameter, leaf area index (LAI), leaves, stem, root, and crop growth rate (CGR), and dry weight of rainfed maize crop. The highest plant height, stem diameter, LAI, leaves, stem, root growth rate, CGR, and dry weight of rainfed maize crop were reported when soil was treated with a higher rate of biochar (36 t ha−1). Biochar increased grain filling rate while decreasing grain filling duration in rainfed maize crops. Our results indicate that straw mulch and biochar-based soil management strategies can improve the rainfed maize growth with the environmental benefits of global warming mitigation. However, due to the wide range of biochar properties, the interactions between straw mulch and biochar should be given special consideration in the maize cropping system

Reflection phenomena of waves through rotating elastic medium with micro-temperature effect

In this article, we analyzed the effect of variable thermal conductivity on reflected elastic waves. The waves are propagating through a thermoelastic medium rotating with some angular frequency. The concept of micro-temperature is also been considered, in which microelements of the medium contain a high temperature. A heat conduction phenomenon is encountered by dual phase-lag heat conduction model. P (or SV)-type wave is incident on the medium with some specific angle of incidence. After reflection from the surface incident, P-wave is converted into quasi longitudinal and quasi transverse waves and propagates back into the medium. Helmholtz’s potential function along with the harmonic wave solution is used to obtain the solution of the model. Analytically, we calculated the amplitude ratios and attenuation factor for each reflected wave against the angle of incidence. The obtained results are also represented graphically for different values of rotational frequency and variable thermal conductivity for a particular material

Epidemiology and management of Fusarium wilt of Eucalyptus camaldulensis through systemic acquired resistance.

Eucalyptus camaldulensis is a multifunctional tree and is globally used for the reclamation of problematic lands. Eucalyptus camaldulensis is prone to attack by a number of pathogens, but the most important threat is the Fusarium wilt (Fusarium oxysporum). Keeping in view the importance of E. camaldulensis and to manage this disease, five plant activators, i.e., salicylic acid (C7H6O3), benzoic acid (C7H6O2), citric acid (C6H8O7), dipotassium phosphate (K2HPO4), monopotassium phosphate (KH2PO4) and nutritional mixture namely Compound (NPK) and nutriotop (Fe, Zn, Cu, B, Mn) were evaluated in the Fusarium infested field under RCBD in the Research Area, Department of Forestry and Range Management, University of Agriculture, Faisalabad (UAF). Among plant activators, salicylic acid and a combination of compound + nutriotop exhibited the lowest disease incidence and enhanced fresh and dry weight of leaves compared to other treatments and control. Results of the environmental study indicated maximum disease incidence between 35-40 °C (max. T), 6-25 °C (mini. T), 70-80% relative humidity and 1.5-2.5 km/h wind speed while pan evaporation expressed weak correlation with disease development. It was concluded that Fusarium wilt of Eucalyptus camaldulensis could be managed through activation of the basal defense system of the host plant with provision of salicylic acid and balanced nutrition by considering environmental factors. Recent exploration is expected to be helpful for future research efforts on epidemiology and ecologically sound intervention of Fusarium wilt of Eucalyptus camaldulensis
