Understanding the seasonal epidemiology of diarrhoea, malaria and pneumonia relative to climatic factors is the thrust of the study. Empirical monthly data sets used covered the period of 2012M1-2019M12. Graphical exploration, methods of seasonal variability and Chi-square test of homogeneity were employed. The results showed that diarrhoea, malaria and Pneumonia are very high at the peak of rainy season (July-September) especially August, when humidity is relatively high and temperature is low. The result also indicted that the null hypothesis of no seasonal variation in the incidence of malaria and pneumonia is rejected in favour of the alternative as Chi-squared values are significant under 5% level respectively. This implies that the incidence of malaria and pneumonia have seasonal occurrence. However, the findings are imperative for the diseases seasonal determination, surveillance and control in Asaba, south-southern Nigeria.

A binomial model is proposed for testing the significance of differences in binary response probabilities in two independent treatment groups. Without correction for continuity, the binomial statistic is essentially equivalent to Fisher’s exact probability. With correction for continuity, the binomial statistic approaches Pearson’s chi-square. Due to mutual dependence of the binomial and F distributions on the beta distribution, a simple F statistic can be used for computation instead of the binomial.

Objective: To evaluate the effectiveness of placing a resorbable collagen barrier in impeding the extrusion of obturation material in primary molars undergoing resorption. Study design: All the 94 canals in 47 mandibular molars were allocated to 2 groups- Group ‘A’- 47 canals with collagen barrier (Test group) and Group ‘B’- 47 canals without collagen barrier (Control group) based on randomization protocol. Pulpectomy was performed and obturation of both test and control canals were radiographically assessed. Pearson’s chi – square test was applied to analyze the results. The significance level was predetermined at p < 0.05. Results: Among the test group, 93.6% of the canals showed no extrusion while, 6.4% showed visible extrusion of the material outside the apex. In the control group, 83% showed no extrusion whereas 17% of the canals showed visible extrusion outside the apex. But no significant difference was noted (p>0.05). Conclusion: The placement of resorbable collagen barrier in the apical third of the canal prevented the extrusion of obturating material beyond the apex in resorbing primary molars.

A new procedure for nonsurgical deep intrauterine insemination (DUI) in non-sedated sows has recently been reported (Martinez et al. 2002 Reproduction 123, 163–170). In comparison to traditional artificial insemination (AI), using this procedure, a 20-fold reduction in the number of spermatozoa inseminated can be used without a decrease in fertility when hormonally treated post-weaning estrous sows are used. The aim of the present study was to evaluate the effectiveness of DUI under field conditions. In Experiment 1, crossbred sows (2–6 parity) were weaned at 20.75 ± 0.06 days. Estrous detection was performed once per day, beginning 3 days after weaning. Sows with a weaning to estrus interval of 4–5 days were selected to be inseminated. A total of 190 sows were inseminated at 12, 24, and 36 h after onset of estrus using one of the following two regimes: (1) DUI with 150 × 106 fresh spermatozoa in 5 mL of BTS (n = 95) and (2) Traditional AI with 3 × 109 fresh spermatozoa in 100 mL of BTS (n = 95) prepared from the same semen samples used for the DUI group. Farrowing rates (FR) and litter sizes (LTS; mean ± SEM) from both groups were compared using chi-squared test and ANOVA, respectively. There was no significant difference in the FR between groups (83.2 and 86.3% for DUI and AI groups, respectively). However, a decrease (P < 0.001) in the LTS was observed in sows inseminated by the DUI procedure (9.8 ± 0.29 and 10.9 ± 0.17, respectively). In Experiment 2, seventy one natural post-weaning estrus sows were used. Fifty-five sows were DUI inseminated three times with 150 (n = 17), 300 (n = 19), or 600 (n = 19) × 106 spermatozoa in 5, 10, or 20 mL of BTS, respectively. The remaining sows (n = 16) were traditionally inseminated. On Day 6 after estrus, sows were subjected to laparotomy and the tips of both uterine horns were flushed in order to evaluate pregnancy rate (PR: percentage of sows with at least 4 viable embryos) and fertilization rate (ratio of viable embryos to the total number of embryos and oocytes). PR was similar in all the groups, ranging from 84.2% (DUI 300 × 106 spermatozoa group) to 94.7% (DUI 600 × 106 spermatozoa group). Fertilization rate and the percentage of bilateral fertilization after DUI with 600 × 106 spermatozoa did not differ from those of the AI group (97.8 and 100% vs. 98.4 and 100%, respectively), but a significant decrease in both parameters (P < 0.05; chi-square test) was observed in sows inseminated with 300 (94.3 and 87.5%) or 150 (84.4 and 66.7%) × 106 spermatozoa. In conclusion, DUI with 150 × 106 spermatozoa offers similar FR but a lower LTS in sows with natural estrus in comparison with those parameters obtained when traditional AI is used. The lower litter size could be related to the low percentage of bilateral fertilization observed in that group. This work was supported by CDTI 020003.

The objective of this study was to determine leucocyte and offspring production of guinea pig (Cavia cobaya) giving Anredera cordifolia leaf extract. Materials used were female 16 heads of guinea pig with body weight of 425g. The treatments were an extract of A. cordifolia leaf at doses of 0, 10, 50 and 90 mg/head, designated as T0, T1, T2 and T3, respectively. A. cordifolia leaf extract was administered orally from 10 days prepartum to 10 days postpartum. Blood was taken at 10 days prepartum and 10 days postpartum. Total birth of the offspring was observed. Data were analyzed by analysis of variance and if there was effect of treatment, then continued with Duncan multiple range test and Chi-Square test for fetal production between the given A. cordifolia leaf extract and control. The result showed that there was no significant difference for 10 days prepartum after addition of A cordifolia leaf extract treatment. The postpartum treated showed a total 50 mg/head level increaed for monocytes than that of level 0, 10 and 90 mg/head. Ten days postpartum treatment showed the total increase for leucocyte and monocytes total were 50 and 90 mg/head, respectively compared to 10 mg/head level. Total lymphocyte of 90 mg/head increased compared to level 10 and 50 mg/head. The highest total neutrophil as found at level of 50 mg/head which increased compared to the level of 0 and 10 mg/head. ProvisioningA. cordifolialeaf extract at doses level of 50 and 90 mg/head could increase litter size (P<0.05; χ2=9.267) and decreased offspring mortality (P<0.05; χ2=6.4). In conclusion, by giving 50 mg/head A. cordifolia leaf extract could increase leucocyte profile and offspring production of guinea pig.

A cross sectional study was conducted in Eastern and Western parts of Chitwan district from November 2015 to April, 2016  in two parts, the social study followed by biological to determine and compare the prevalence, distribution of antibodies, and level of awareness of farmers  against Brucella abortus in cattle of the two regions of same district. Altogether blood samples of 92 cattle were taken for detection of Brucella antibodies by using RBPT test and the positive samples were further retested by Indirect ELISA test through ID Vet iELISA kit 2016. The samples which showed positive on both tests were confirmed as seropositive. Chi -square test and Fisher Exact test was used to find out the association between various variables. The result showed that 14.13% (13/92) and 10.86% (10/92) sample were positive by RBPT and iELISA test respectively. There was no significant prevalence differences (p>0.05) on location, age group, breed type, and method of service (artificial and natural) used in cattle. Comparing abortion with prevalence of Brucellosis, there was significant differences (p<0.05) in the result of both RBPT and iELISA test. Inferring from this result, there is association between the abortion and occurrence of Brucellosis. The higher significant prevalence differences (p<0.01) was according to the time of abortion where higher seropositivity was obtained in the cattle aborted on 5-7th month of pregnancy and cattle of 3rd parity. The study showed the existence of Brucellosis in Chitwan district with no adoption of any preventive measures against this disease, so here is current need of the strategies for its prevention and control in order to mitigate such overwhelming situation.Int J Appl Sci Biotechnol, Vol 4(3): 365-371

 This study presents an attitude of female students studying B.Ed. third year towards physical education and sports within Kathmandu valley. Initially, it was hypothesized that there is no significance difference in attitude of physical education and sports among female students of different campuses. From these 6 campuses, 184 female students were randomly selected. A five-point Likert-type scale was applied for data collection from the selected students who studied in B.Ed. third year. Altogether five opinion statements were used for data collection. It was found that all respondents showed positive attitudes towards physical education and sports. In order to test whether there is significant interdependence in score among the respondents in different perspectives. The chi-square test score was applied as statistical test at the 0.05 level of significance. The chi-test under contingency table: independent of opinion among the respondent, if (χ2>α=0.05 in different degree of freedom) and independent if (χ2≤ α=0.05 in different degree of freedom). For the measurement of attitude for physical education and sports,it has enough evidence in the data to accept alternatives hypothesis; there is relation or interdependence of attitude towards physical education and sports among the respondents. Because, the score is very high among the response of respondent. The study suggests that the university teacher must be accountable to construct professional environment.

El propósito de esta investigación es analizar las relaciones entre las condiciones de contratación y el absentismo laboral en una muestra de 5524 trabajadores, con el fin de identificar qué segmentos (por tipo de contrato y jornada, tiempo contratado, antigüedad en la empresa y bajas por enfermedad ocurridas en los tres últimos años) están más relacionados con la posibilidad de sufrir un proceso de enfermedad en el año 2017. Se realizaron análisis descriptivos, la prueba chi-cuadrado para tablas de contingencia con dos muestras independientes y los árboles de decisión, basados en el algoritmo CHAID (Chi-squared Automatic Interaction Detection), para detectar las variables más importantes en la identificación de perfiles con una mayor probabilidad de sufrir una incapacidad temporal. Los resultados ponen de manifiesto la existencia de diferencias entre las variables estudiadas. Se considera la modalidad de contratación un factor de riesgo importante del absentismo laboral. The purpose of this research is to analyze the relationship between hiring conditions and work absenteeism in a sample of 5.524 workers in order to identify which segments (by type of contract and workday, time hired, seniority in the company and sick leaves occurred in the last three years) are more related to the possibility of suffering a disease process in 2017. Descriptive analyzes, the chi-square test for contingency tables with two independent samples, and the decision trees based on the CHAID algorithm (Chi-squared Automatic Interaction Detection) were carried out to detect the most important variables in the identification of profiles with a greater probability of suffering a temporary disability. The results show the existence of differences between the variables studied. The hiring modality is considered an important risk factor for work absenteeism.

Atopic dermatitis (AD) is a chronic, relapsing, highly pruritic skin condition that develops in early childhood. Sleep problems are common in AD children and lead to impaired quality of life, disturbance of neurocognitive function and behavior. The aim of this study was to assess the prevalence of sleep problems in 0-36 months old Indonesian children with AD. Children aged 0-36 months were enrolled, divided into two groups, AD and control. Sleep problems and AD were assessed using Brief Infant Sleep Questionnaire (BISQ) and Severity Scoring of Atopic Dermatitis Index (SCORAD). Chi-square test was performed to compare the outcome. There were 35 children participating in each group. In children with sleep problems, 85.7% were diagnosed with AD and 11.4% were non-AD. Nocturnal sleep duration, night waking, nocturnal wakefulness, sleep onset time, method of falling asleep and parental consideration of sleep problems occur more often within AD group. Severity of AD also significantly contributes to sleep problems in AD group. In conclusion, this study showed that sleep problems are more prevalent in children with AD.
