A teacher should be just and compassionate to be a good teacher. If there is weakness in these two, what a pity for those children who are trained by that teacher! Because one of the biggest diseases of this time is that mercilessness and unjustness are the raising trends. The purpose of this study is to analyze the mercy levels of the classroom teachers in terms of different variables. The study was conducted on 227 classroom teachers, 132 females and 95 males, working in Ağrı Province, Turkey in 2017.In the study, the Compassion Scale (CS) developed by Pommier (2011) and adapted to Turkish by Seher Akdeniz and Mehmet Engin Deniz was applied to the teachers. A statistical program was used to analyze the data. Frequency distribution to determine demographic characteristics, t test to analyze the relationship between compassion level and two independent variables, and ANOVA variant analysis to analyze the relationship between compassion level and variables more than two were used in the analyses of the data. The difference between the variables was interpreted on the basis of p0.05 significance level.According to the findings, it was determined that there is a significant difference between the level of compassion of the teachers and the gender, the settlement they work in, and their term of office. It was determined that the mean scores of male teachers were higher than the female teachers in the dimensions of indifference, disconnection and intercourse in the sub-dimensions of compassion level, the mean scores of the teachers working in the village in the sub-dimension of being aware of the sharing is higher than the teachers working in the city, and the mean scores of the teachers with 6-10 years of period of office is higher than those with 16 years of period of office in the sub-dimension of being aware of the sharing and the mean scores of the teachers with 5 years and below of period of office is higher than those with 6-10 years of period of office in the sub-dimension of disengagement.It can be recommended that increasing the compassion levels of the teachers in social and school life will have a positive effect on their relationships with students. It is also of higher importance to analyze other variables which are thought to positively affect compassion.

In a typical science curriculum with different scientific disciplines (Chemistry, Biology, Physics and Earth Sciences) taught in every quarter, it is important to determine the difference in the performance of students under each discipline.  In this study, the comparison of quarterly performance in Science of Grade 7 Students was examined. Wherein, the consolidated quarterly grades in science from the previous school year (June 2018 - April 2019) from five sections with a total of 272 male and female grade 7 students were used as data. It employed a quantitative research design using a One-way Analysis of Variance ( ANOVA) to determine the significant difference in the mean grades per quarter. Additionally, an interview with the science teachers who handled the samples was conducted to gather qualitative data to further explain the results. The results of this study revealed a mean of 83.50 from the combined grades in the second quarter which is the lowest among the four quarters. However, the results from ANOVA  generated a significance of .123 (p≥.05) which means that there is no significant difference between the grades in the first, second, third and fourth quarter.

Abstract Objectives The study aimed to evaluate and compare various commercially available local anesthetic solutions. Materials and Methods A total of 150 commercially available local anesthetic cartridges of similar composition (2% lidocaine with epinephrine 1:100,000) were randomly collected and divided into 3 groups. The designations of groups were selected from their product names such that each group consisted of 60 cartridges. Group S (Septodont, France) Group M (Medicaine, Korea) and Group H (HD-Caine, Pakistan). The samples were divided into five sub-groups, each consisting of 10 cartridges from each group to investigate each parameter. Results The acquired data was statistically analyzed and compared (using SPSS version 12). Compositional analysis revealed a non-significant (P>0.05) difference when the three Groups were compared with standard lidocaine and epinephrine solutions. The mean pH values of samples from group S, M and H respectively fell within the range of pH values of commercially available solutions. Non-significant difference in EPT values of Group S and H was found when efficacy was compared (p = 0.3), however a significant difference (p < 0.01) was observed in contrast to Group M. Anti-bacterial activity was observed in all the group and a non-significant difference in cell viability values of Group S and M was found (p = 0.6), while the difference was significant in comparison to Group H. Conclusion Within the limitations of these investigations, it appears that the properties of different manufacturers fall within the recommended ranges as mentioned in literature and do not appear to be statistically different in the variables we have tested.

The mean length of gestation was 114 days for both gilts and sows.3. The mean numbers of pigs born alive and born dead per litter from gilts, 10·0 and 0·2 respectively, were both significantly smaller than the corresponding figures for sows, 11·8 and O·8. No seasonal differences were found.4. The mean total losses of pigs from birth to weaning at 8 weeks were 29·5% of pigs born alive. The losses in litters from gilts, 23·0%, were significantly smaller than in litters from sows, 31·0%. The losses during the winter months both for gilts, 32·5%, and for sows, 35·9%, were significantly higher than during the summer months, 19·4% and 26·7% for gilts and sows respectively.5. Over 50% of the total losses were due to crushing by the dam, 74·1% of the losses from this cause occurring during the first 48 hr. after birth.6. The mean number of pigs weaned per litter was 8·0. The difference between the number weaned per litter from gilts, 7·7, and per litter from number of pigs was weaned per litter from sows during the summer months, 8·7, than during the winter months, 7·4.7. There was no significant difference between the number of male and of female pigs weaned.8. The mean weight at weaning was 29·9 lb., male pigs, 30·3 lb., being significantly heavier than females, 29·51b. Pigs in litters from gilts, 27·81b., were significantly lighter at weaning than those from sows, 30·0 lb., and for both gilts and sows, pigs reared during the summer months, 29·7 and 31·8 lb. respectively, were significantly heavier than those reared during the winter months, 25·9 and 28·2 lb. respectively.

This study evaluated the influence of apical patency, root filling removal technique and cleaning of the apical foramen, concerning the amount of debris extruded during root canal retreatment. Forty mandibular incisors were randomly assigned to 4 groups - GIM (n=10), GIIM (n=10), GIPT (n=10) and GIIPT (n=10), which were named according to leaving (I) or not (II) apical patency during canal preparation and filling removal technique (manual - M or ProTaper system - PT). After filling material removal, each specimen of each group had the apical foramen cleaned by sizes 15, 20 and 25 instruments, generating 12 subgroups: GIM15, GIM20, GIM25, GIIM15, GIIM20, GIIM25, GIPT15, GIPT20, GIPT25, GIIPT15, GIIPT20 and GIIPT25. Extruded filling debris was collected by a Milipore filtration system, an HV-durapore, 0.45 µm pore filter with a 25 mm diameter. The filters were weighed before and after the collection on an analytical scale (10–5 g), and the difference was calculated. The mean weight of extruded filling debris was analyzed statistically by Kruskal-Wallis and Friedman ANOVA tests (α=0.05). The mean values found in the groups (in mg) were: GIM (0.95±0.94), GIIM (0.47±0.62), GIPT (0.30±0.31) and GIIPT (0.32±0.44). There was no statistically significant difference among any of the groups or subgroups (p>0.05). ProTaper provided the smallest amount of extruded filling material, regardless of presence or absence of apical patency, followed by manual technique, without and with apical patency. Additional amounts of debris were collected during cleaning of the apical foramen, regardless of the instrument, presence/absence of patency or root filling removal technique.

Introduction: Cigarette smoking is a prime risk factor for cardiovascular morbidity and mortality. Chronic smoking results in autonomic dysfunction leading to increased cardiovascular risk in smokers. The present study was planned to study the effect of smoking on the Cardiovascular Autonomic Functions among smokers. Materials and Methods: Fifty male subjects who were in the age group of 25 to 45 years. They were grouped into 25 smokers and 25 non-smokers. The participant subjects were selected among the staff members, residents and the patients from the routine OPD in SVIMS. Prior to study, they were informed about the procedure and the purpose of the study tests and written consents were obtained from them. The Cardiovascular Autonomic Function Tests were assessed by using a POLYGRAPH which was available in the department. Results and Conclusion: After applying the ‘t’-test for the difference between the two sample means, it was observed that there was a highly significant difference between the mean values of the BMI(i.e.p<0.01) and the para-sympathetic function tests among the smokers and the non – smokers(i.e.p<0.00). The Resting Heart Rate had significantly increased and the Deep breathing difference, the postural tachycardial index (Response to standing) and the Valsalva Ratio had significantly decreased in the smokers as compared to those in the non – smokers. After applying the ‘t’-test for the difference between the two sample means, it was observed that there was no significant difference between the mean values of the Postural hypotension test (i.e. p>0.05) and that there was a highly significant difference between the mean values of the Sustained handgrip test in the smokers and the non – smokers (i.e. p<0.00). KEY WORDS: Cardiovascular autonomic function tests, Smoking, Resting heart rate.

Background: Childhood asthma is affected by events and conditions of the school environment. Teachers as de-facto caregivers of children with asthma have a major role to play in ensuring good asthma control in school. This study set out to determine the level of knowledge of school teacher about childhood asthma and factors influencing this knowledge.Methods: Four secondary schools (two private and two public) in Ilesa, South West Nigeria were selected by multistage sampling method. All the teachers in these schools were required to fill a self -administered questionnaire incorporating a validated 40-item asthma knowledge questions. Factors associated with the level of knowledge were determined appropriately.Results: A total of 132 teacher (M: F = 1:2) participated in the study with 85 (64.4%) from private school. The mean (SD) age of the teachers was 38.0 (9.1) years and median (IQR) years in teaching service was 7.0 (5.0 to 15.0) years. Majority (56.1%) of the teachers had university education while only 7 (5.3%) had a post graduate degree. The mean (SD) score of the 40 item questions was 21.5 (7.2) and majority (51.5%) had poor asthma knowledge (score < 22). Poorer knowledge was observed in questions related to the nature and management of childhood asthma than triggers and manifestations. No significant correlation was found between knowledge and age, teaching experience and qualifications (p > 0.05). However, teachers with previous training about childhood asthma had relatively good knowledge about the condition. (p <0.05)Conclusion: The level of knowledge about childhood asthma among school teachers in Ilesa is poor particularly as regards to nature and management of the disease. We advocate for training of school teachers about common childhood conditions including asthma to ensure optimal symptoms control in school.Keywords: Childhood asthma, Knowledge, School teachers

Background: The emergence of chronic physiologic diseases such as diabetes damages the children's psychological, cognitive, communicational, social and emotional processes. Therefore, the present study was aimed to compare executive functions in normal and diabetic children. Methods: The research method was cross-sectional. The statistical population included healthy and sick children in 2019 in Isfahan. The statistical population of the study included diabetic children and 150 healthy children who were selected through convenient sampling method. The applied questionnaires were the executive functions. The data from the study were analyzed through t method. Results: There is a significant difference between diabetic children and healthy ones in the variable of executive functions (p < 0.001). In a way that diabetic children got lower mean scores in executive functions. The mean scores of executive functions of children with diabetes were 233.63 and the mean scores of non-children with diabetes were 192.64. Conclusion: According to the findings of the present study it can be concluded that diabetes causes the decrease of executive functions due to being chronic and this process emphasizes the necessity of applying child-oriented psychological interventions for these people.

Objectives: Seizure is the fourth most common neurological disorder in the world; it affects all age groups with equal possibility of occurrence in both males and females. Many antiepileptic drugs are available today, but its diagnosis is challenging. The present study attempted to see if seizure activities could be predicted by analyzing the pre-seizure electrical activities. The prediction may help in taking preventive measures appropriately beforehand in the individuals with seizure proneness. Material and Methods: We selected 11 generalized seizure patients and 19 control patients out of total 115 patients referred for electro-diagnostics for various reasons. EEG of the subjects recorded, segmented as per protocol, and analyzed using MATLAB and EEGLAB tools. Results: The mean energy level in alpha and beta band of the study subject was significantly lower (P = 0.04 and 0.004, respectively) as compared to the age matched control subjects. Theta and delta bands did not show any significant difference between the groups. The difference between the pre- and post-electrical seizure energy and entropy was statistically insignificant. Conclusion: The study shows that the energy level remains low in the seizure patients in the alpha and beta bands. This further goes down when electrophysiological seizure activities starts. The randomness or entropy does not alter significantly among the seizure subjects in comparison to non-seizure subjects.

Malaria and HIV are the two most important health challenges of our time. Haematologic abnormalities are features inPlasmodium falciparuminfection, and anaemia is a well-known outcome. The prevalence and haematological impact ofP. falciparumparasitaemia were determined among HIV-infected individuals in Nigeria. Parasite detection was carried out using microscopy and Polymerase Chain Reaction (PCR). Haemoglobin concentration was determined using an automated machine while CD4+ T-cells count was analyzed using flow cytometer. Thirty-seven (18.5%) out of the 200 HIV individuals enrolled had malaria parasites detected in their blood. All the positive cases were detected by PCR while only 20 (10%) were detected by thick blood microscopy. The mean haemoglobin concentration and packed cell volume (PCV) of HIV individuals with malaria parasitaemia were lower compared to those without malaria parasitaemia but the difference was not statistically significant. Also no significant difference was observed in malaria positivity in respect to sex and mean CD4+ cell count. The study highlights the effects ofP. falciparumparasitaemia on the haematologic and immune components of HIV individuals.
