Teaching Ability

Teachers have an important role in making human resources useful for national development. The teacher uses many teaching methods and methods for classroom activities. Presently more emphasis is being laid on providing qualitative education. Creative aptitude in teaching nurtures students' creativity. By which they can be used to ensure available physical and human resources and ensure satisfactory results. The Yashpal Committee (1992), laid the main emphasis on the development of independent thinking and self-learning capacity of the students in the teacher training program. Teaching skills competence of teachers is an important factor in setting up the best level educational institutions. Due to which the students are attracted and give priority to such institutions. The reason behind which is to work with creative aptitude in the teaching style of the teachers teaching them. RTE, Teacher Eligibility Test (TET) and B.Ed in education to develop the professional competence of the students. Adequate opportunities for teaching training have been accommodated for the quality of teacher education, etc. for two years of one year course of training.In the research paper presented, two-year new B.Ed. The creative attitude and teaching competence of the students of the course has been studied. In descriptive research, 132 students were taught in fifteen internship schools teaching practice in the arts and science class by simple random sampling method. Compilation of data BK Passy and Dr. M / s. Lalita's standardized general teaching competence measure and Dr. RP Shukla's creative teaching aptitude measuring tools were used in the compilation of data. Statistical methods such as percentage, mean, standard deviation, t-value and Pearson correlation coefficient were used in statistical analysis of the data obtained by the research survey. It has been revealed by the conclusion that- 1.) Similarity was found in teaching ability of art and science students but significant difference in mean level of creative teaching aptitude. 2.) There is a positive correlation between the teaching competence and creative aptitude of art class students and 3.) There is a positive correlation between teaching ability and creative aptitude of science class students. राष्ट्रीय विकास के लिए मानवीय संसाधन को उपयोगी बनाने में अध्यापकों की अहम् भूमिका है। कक्षागत् क्रियाकलापों के लिये अध्यापक अनेक शिक्षण युक्ति एवं विधियाँ प्रयोग करता है। वर्तमान में गुणात्मक शिक्षा उपलब्ध कराने पर अधिक बल दिया जा रहा है। शिक्षण में सृजनात्मक अभिवृत्ति छात्रों की रचनात्मकता को पोषित करती है। जिससे वे उपलब्ध भौतिक एवं मानवीय संसाधनों का समुचित प्रयोग करके संतोषजनक परिणामों को सुनिश्चित किया जा सकता है। यशपाल समिति (1992), ने शिक्षक प्रशिक्षण कार्यक्रम में छात्राध्यापकों के स्वतंत्र चिंतन व स्व-अधिगम क्षमता के विकास पर मुख्य जोर दिया। उत्तम स्तर के शिक्षण संस्थानों को स्थापित करने में अध्यापकों की शिक्षण कौशल सक्षमता एक महत्वपूर्ण कारक है। जिससे आकृष्ट होकर छात्र ऐसे संस्थानों में प्रवेश को प्राथमिकता देते है। जिसके पीछे उनमें पढ़ाने वाले शिक्षकों की अध्यापन शैली में रचनात्मक अभिवृत्ति से कार्य करना है। छात्राध्यापकों की पेशेवर सक्षमता को विकसित करने के लिए शिक्षा में आर.टी.ई., अध्यापक पात्रता परीक्षा (टी.ई.टी.) एवं बी.एड. प्रशिक्षण के एक वर्षीय पाठ्यक्रम को दो वर्ष करना आदि अध्यापक शिक्षा की गुणवत्ता हेतु शिक्षण प्रशिक्षण के पर्याप्त अवसरों को स्थान दिया गया है। प्रस्तुत शोध पत्र में द्विवर्षीय नवीन बी.एड. पाठ्यक्रम के छात्राध्यापकों की शिक्षण के प्रति सृजनात्मक मनोवृत्ति एवं शिक्षण सक्षमता का अध्ययन किया गया है। वर्णानात्मक शोध में पन्द्रह प्रशिक्षुता (इंटर्नशिप) विद्यालयों में शिक्षण अभ्यास करने वाले 132 छात्राध्यापकों का चयन साधारण यादृच्छिक प्रतिचयन विधि द्वारा कला एवं विज्ञान वर्ग द्वारा किया गया। आँकड़ों का संकलन डाॅ. बी.के. पाॅसी एवं डाॅ. एम.एस. ललिता की मानकीकृ्रत सामान्य शिक्षण सक्षमता मापनी तथा डाॅ. आर.पी. शुक्ला के सृजनात्मक शिक्षण अभिवृत्ति मापनी उपकरणों का प्रयोग आॅकडों के संकलन में किया गया। शोध सर्वेक्षण द्वारा प्राप्त आंकड़ों का साख्यिकीय विश्लेषण में प्रतिशत, मध्यमान, प्रमाणिक विचलन, टी-मान एवं पियर्सन सहसम्बन्ध गुणांक आदि सांख्यिकी विधियों का प्रयोग किया गया। जिससे प्राप्त निष्कर्ष द्वारा विदित हुआ है कि- 1.) कला एवं विज्ञान छात्राध्यापकों की शिक्षण सक्षमता में समानता लेकिन सृजनात्मक शिक्षण अभिवृत्ति के मध्यमान स्तर में सार्थक अंतर पाया गया। 2.) कला वर्ग के छात्राध्यापकों की शिक्षण सक्षमता एवं सृजनात्मक अभिवृत्ति के मध्य सकारात्मक अनुबन्ध है तथा 3.) विज्ञान वर्ग के छात्राध्यपकों की शिक्षण सक्षमता एवं सृजनात्मक अभिवृत्ति में धनात्मक सहसम्बन्ध है।

BACKGROUND Measurement of chest expansion is commonly done in physical examination of patients as it gives reliable idea about the rib cage mobility & capacity of lungs along with thorax to expand. Chest expansion values are reduced in diseases and it can be used to check progression of the diseases. In India there is lack of reference data on chest expansion due to which the values derived from other population are used for reference in India. Comparison of the patient with wrong population data will create misinformation & wrong diagnosis. This study was designed to establish reference value for expansion of chest in healthy Indian children, understand relation of age, height, and weight with chest circumference & compare these values with published global values. METHODS Chest expansion & circumference of chest was measured in 229 boys and 226 girls aged 6 – 15 years. The study was conducted in Mumbai metropolitan region and Navi - Mumbai. Standing height, weight, age, sitting chest circumference and chest expansion were recorded. Chest expansion was measured at three different levels i.e. axillary, mammary and xiphoid. The correlation coefficient was used to understand relation of age, weight, height with chest expansion & chest circumference. The prediction equation was derived for both genders separately by multivariate regression. RESULTS Significant positive correlation of chest circumference was observed with age and weight and negative correlation with height. Chest expansion was higher in males as compared to females. Chest expansion had shown positive correlation with age, height and weight. Pearson correlation coefficients were 0.927, 0.885 & - 0.337 respectively. Different prediction equations were drawn for males and females for expansion of chest at all three levels. Significant difference was noted in values of this study and global values. CONCLUSIONS Gender wise differences exist in chest expansion values. Males have higher values than females. Hence gender specific equations are needed for estimation of chest expansion.

Abstract Purpose: To analyze the changes of near binocular vision function after small incision lenticule extraction and association with asthenopia. Methods: This was a retrospective study．Twenty-five myopic patients who underwent small incision lenticular extraction (SMILE) surgery from Tianjin Eye Hospital were included in this study．The values of parameters of near binocular vision function were measured at preoperative, 1 week, 1 month and 3 months postoperatively including near heterophoria, near point convergence (NPC), horizontal base-in fusional reserves (BIFR) and base-out fusional reserves (BOFR). The patients were grouped by the preoperative symptoms scores. The comparisons among different follow-up periods were conducted by the repeated measures analysis of variance. The Pearson correlation coefficient (r) was used to evaluate the linear fit of the relationship between variables. Multiple linear regressions were used to analyze the relationship between asthenopia and parameters of binocular and accommodative function. Results: The NPC significantly increased at 1 week and 1 month after SMILE and then get back to the level of preoperatively in 3 months postoperatively. Near heterophoria significantly decreased at 1 week after SMILE and then remained stable in 3 months postoperatively. In the regression analysis, there was no significant association between the values of the fatigue questionnaire at different stages after SMILE operation and the parameters of near binocular visual function (P>0.05). However, there was significant positive correlation among each visit with the preoperative visual fatigue questionnaire（P<0.05). There was no significant difference in the parameters of binocular visual function between the normal group and the fatigue group. For the visual fatigue group, there was positive correlation between the score of visual fatigue questionnaire 1 week after SMILE surgery and the difference in near horizontal phoria between 1w postoperative and that preoperative (r=0.523, P=0.046), and significant negative correlation with the recovery point of BOFR at 1 week (r=-0.581, P=0.023). Conclusion: SMILE surgery wouldn’t influence the binocular vision in the short term. Since there was no significant association between binocular vision function and visual fatigue, factors of asthenopia in the early period of SMILE surgery should be further studied.

Abstract Background Selection into UK medical school typically involves a combination of three measures: prior academic attainment, selection tests (e.g., the University Clinical Aptitude Test (UCAT), Biomedical Admissions Test (BMAT), Graduate Medical School Admissions Test (GAMSAT)), and an interview. We investigated whether prior attainment and selection test scores can predict MRCS success. Method We used the UKMED database to analyse selection data for all UK graduates who attempted MRCS Part A (n = 9729) and Part B (n = 4644) between 2007-2017. Univariate analysis and Pearson correlation coefficients were used to examine the relationship between selection scores and first attempt MRCS success. Results Successful MRCS Part A candidates had better A-Levels and higher scores in UCAT, BMAT and GAMSAT examinations (p &lt; 0.001) than their unsuccessful peers. No statistically significant difference was observed for MRCS Part B. A moderate positive correlation was found between Part A, BMAT (r = 0.315, p &lt; 0.001) and GAMSAT scores (r = 0.346, p &lt; 0.001). A weak positive correlation was found between Part A, A-Level (r = 0.144, p &lt; 0.001) and UCAT scores (r = 0.246, p &lt; 0.001). Conclusions A-level results and medical school selection tests predict success in the knowledge-based (Part A) MRCS examination.

The status accorded to adult education among universities-based educators and researchers appears to be very low. This may be due to scanty knowledge about the discipline and wrong perception held by the bureaucrats, policy makers and administrators within and outside the university system. The Hamburg Declaration in 1997 underscores the importance of adult education when it describes it as a key to the twenty-first century. Realising the fact that adult education is needed in this 21st century, it follows that provision of higher degree programme should be well staffed and properly managed in order to produce learners that will contribute meaningfully to the development of the society. Therefore, this study entitled: “staffing and managing human resources of higher degree programme of adult education in universities in Nigeria” is embarked upon. The aim of the study is to improve human and institutional capacity for required manpower in adult education for national development. The objectives of the study include: to identify and discuss framework for staffing higher degree programme in adult education in Nigerian universities; to find out how human resources for production of higher degrees students are sourced and managed; to assess framework for ensuring inclusiveness in managing higher degree adult education programme in universities; to explore strategies that can be employed to make adult education popular and acceptable among educators and researchers in universities; to explore motivational factors for students' enrollment in adult education higher degree programme; and to examine learning delivery techniques of lecturers/faculty in higher degree programme of adult education. The work employed research design of the survey type. Seven federal and state universities offering adult education at higher degree level were sampled. Statistical instruments were employed to analyse the data collected. All the results were decided at point 05 level of confidence with appropriate degree of freedom. The study revealed that 86.3% of the respondents opined that lack of understanding of the concept of adult education prevented people from enrolling into the course in the university, while 13.7% felt otherwise. Majority of the respondents (89.8%) held that Universities in Nigeria do not discriminate against any sex (male or female) when admitting students for any education programme including adult education, while 10.2% did not. There is significant difference in the perception of staff and students on the framework that can be used for staffing higher degree programme in adult education in Nigerian universities (X2=2.882, df=3, p > .05). There was no significant difference in the perception of staff and students on how human resources are sourced and managed for production of higher degree students in adult education programme (X2=3.741, df=3, p > .05). There was a significant difference in the perception of staff and students on learning delivery techniques of lecturers/faculty in higher degree programme of adult education (X2=9.336, df=3, p < .05). It is recommended that efforts should be made by the stakeholders to popularise the discipline of adult education with a view to making people to understand its meaning and usefulness to the growth of the society. Adequate budgetary allocation should be made by the owner universities to adult education so as to attract qualified staff, regular payment of salaries and comprehensive welfare programme.

ABSTRACT: Brazilian Association of Crioulo Horse Breeders (ABCCC) establishes minimal and maximal body biometrics evaluation; although, nothing is mentioned about testicular measurements. Body and testicular growth are associated and related to age. We described data regarding body and testicular biometry of Crioulo stallions, with a comparative study between young and adult categories. Evaluation was performed in 56 stallions, Crioulo breed, split in: youngsters (3 and 4 years-old, n=16) and adults (above 5 years-old, n=40). Body biometry included weight, height, cannon bone and chest circumference, body score condition and neck fat accumulation. Testicular biometry included height, length, width, volume, combined volume and daily sperm output (DSO). Statistical analyses included descriptive statistic, Pearson correlation, comparison between means by Kruskal Wallis, being P < 0.05 considered significant. There was no significant difference between the parameters of body and testicular biometrics between categories young and adult. In relation to height, the average was very close to the lower limit established, while chest and cannon bone circumference were above the minimum recommended by ABCCC. Cannon bone circumference presented a positive correlation with height. Most of stallions presented excessive body fat, with a body score condition above 8 (scale 1-9). Neck fat accumulation presented a positive correlation with body score condition. Testicular height, length, width and volume presented a positive correlation between the ipsi and contralateral testicle, total testicular volume and DSO. In conclusion, no difference in the body and testicular biometric evaluation was observed between young and adult Crioulo stallions. Testicular and body growth are associated and also related to age, so our finding suggested that after 3-4 years-old most of Crioulo stallions have already reached maximum growth.

In a postindustrial economic world, information economies are key components in local, regional and national development. These are service economies, built on the production, consumption and dissemination of information, including education, health care, outsourcing, tourism, sustainability and related human welfare services. We explore the geography/knowledge intersections in Poland’s voivodeships and poviats by using the volumes of information or hyperlinks about selected information economies. Google hyperlinks are electronic knowledge data that can be mapped to highlight the areas of most and least information about certain subject categories. While some mapping results are expected, such as Warsaw and Krakow, being prominent, in other regions there are unexpected gaps within eastern, northern and southern Poland, including some places near major metropolitan centers. There is a significant difference between the cities with poviat rights, which stand out in the number of information on items comparing to the poviats that surround them. The majority of poviats in Mazowieckie voivodeship are surprisingly recognized as core areas on the map of knowledge, nevertheless they are considered undeveloped from the economic point of view.

The aim of this study is to investigate the effects of participation in a 1-week summer camp on thehopelessness and self-esteem of the university students attending Sport Sciences Faculty. Participants were 36university students assigned to experiment group using a random procedure. Coopersmith Self-esteem and Beck Hopelessness Scales were completed at the beginning and end of the summer camp by designed the university. The obtained data were analysed in the SPSS 18.0 program and the significance level was taken as 0.05. The descriptive statistics, independent simple t test, paired simple t test and Pearson correlation were used for analyse the data in the study. According to the results of the research, no significant difference was observed in the comparison of the hopelessness and self-esteem levels between pre and post-test. In addition, there was a significant difference in the hopelessness level of male and female students but any significant difference was not observed in terms of self-esteem. There was a significant relationship between hopelessness and self-esteem pre and post-test. These result shows that a 1-week summer camp cannot change the hopelessness or self-esteem level. However, as the self-esteem rises, the rate of despair decreases whereas as the despair rises, the selfesteem decreases.

Coriander Leaves

Coriander (Coriandrum sativum L.) is one of the herbs which is used for medicinal and food purposes. In the present study the levels of selected metals in coriander leaves were determined in the samples collected from four different farmlands (Sebeta, Mekanisa, Holeta and Gefersa) in Ethiopia where its cultivation is common. The levels of metals were determined after digestion of samples with the mixture of 4 mL of HNO3 and 4 mL of HClO4 at 300 oC for 3:00 hours by flame atomic absorption spectrometry. The optimized wet digestion method for coriander leaves analysis was validated through the recovery experiment and a good percentage recovery was obtained (93.2-101%). The levels of metals were found in the range Ca, 2319–3503 mg/kg; Zn, 33.4–54.8 mg/kg and Cr, 5.55-9.86 mg/kg while the trace metals Cu, Ni, Cd and Pb were too low to be detected. The results indicated that Ethiopian coriander is a good source of essential metals and free from the toxic metals Pb and Cd. A statistical analysis of variance (ANOVA) at 95% confidence level indicated that there is significant difference (p &lt; 0.05) in the levels of all detected metals between the four sample means. The Pearson correlation was used to predict the dependence of metal levels on one another. The levels of the metals determined in this study compared well with those reported for coriander leaves from some other parts of the world.
