Agricultural Innovations

The contribution of new technology to economic growth can only be realized when and if the new technology is widely diffused and used. Diffusion itself results from a series of individual decisions to begin using the new technology, decisions which are often the result of a comparison of the uncertain benefits of the new invention with the uncertain costs of adopting it. An understanding of the factors affecting this choice is essential both for economists studying the determinants of growth and for the generators and disseminators of such technologies. The study was to determine the factors affecting farmer’s adoption of improved agricultural innovation in Welmera district western part of Oromia regional state Ethiopia. Non replaceable lottery method and proportional to size sampling techniques were employed for the selection of 130 respondents; structural questionnaires and group discussion were used. Data were analyzed using Statistical tests like chi-square, t-test, one way ANOVA and econometric model Tobit was used to identify the effect of the hypothesized variables on the dependent variable. The result of the econometric model indicated that the educational level of respondent, total land holding, accesses to research and access to the extension were found significant to influence the adoption of improved potato production packages. The mean average age of sample respondent was 45-54. The independent t-test result shows that there was no significant difference between adopter categories in terms of age to the adoption of improved potato technology (t=1.747, p 0.991). From the sample household heads 13.85% of respondent farmers are illiterate and the remaining 86.15% are educated. Majority of high adopters have been educated from grade 5 to 10 Chi-square test also shows the significant difference between adopter categories of improved potato technologies (χ2=17.25a, P=0.004). It is time to look participatory extension approach which invites different stakeholders. FRG approach contributed a significant role in the diffusion and adoption of agricultural innovations.

Background : Numerous research have been made to find out contributive factors of the exclusive breastfeeding.Objective: The objective of this study was to find out whether mothers’ nutritional status had any influence on the exclusivity of breastfeeding and  on the growth of their babies up to 4 months.Methods: This observational study was carried out with a prospective cohort design and lasted from November 2004 to May 2005. The subjects were 80 pairs of mother and baby treated at the Obstetric and Gynecology Unit (UPF) of Local Public Hospital (RSUD) Prof. Dr. W.Z. Johannes at Kupang – NTT. The subjects were divided into two groups namely Undernutrition status group marked by <23,5 cm mid arm-circumference, and control group comprised 46 mothers of well- nutrition  status who had bigger mid arm-circumference >23,5 cm. Observed babies were those of normal or spontaneous delivery, non twin with >2500 g birth weight. Follow up observations were made at family home and the data on breastfeeding characteristics were collected by interview, babies weight were measured by Secca baby scale with 0,01 kg level of accuracy mid arm-circumference was measured by means of LILA tape, and body length was measured using length-board. Tools measure with 0,1 cm level of accuracy. Some statistical tests were used namely Chi-Square; student’s t-test; and while Kaplan Meier log-rank test as needed.Results: More than 50% of under-nutrition mothers were under 25 years old. Chi-Square test shows that significant difference between mother’s age was (p=0,04). More than 50% of the KEK group gave birth for the first time or ‘primipara’ (p=0,25). Kaplan Meier analysis showed that  there was no difference between survival median of breastfeeding be- tween the both group (p=0,53). t-test showed that there were significant differences of the babies body weight of the both KEK and non KEK mothers, namely pd”0,01, p=0.01, and p=0.03 in the first, second, third, and the fourth month respectively. In terms of the average babies body length, the t-test also showed significant differences between both groups with p=0.02 and p=0.01 in the third and the fourth month respectively.Conclusion: I can be concluded that mother’ nutrition status did not have any influence on the exclusivity of breastfeeding, however, it did significantly influence babies growth from 0- 4 month.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Abstract Background: The aim of the present study was to assess readiness to become or stay physically active according to the Stages of Change Model.Methods: The present quasi-experimental study was conducted on 100 women working in the healthcare centres of Bandar Abbas, Iran. The sampling method is clustering in type. The subjects were assigned into two groups of intervention and control. The collected data were analysed by SPSS-16 software using descriptive and inferential statistics, including independent-sample t-test, paired-sample t-test and Chi-square test.Results: Before the educational intervention, 19 subjects (0.38%) from the intervention group showed to have regular physical activity (4-5 stages). This number changed to 29 (0.58%) and 25 (0.50%) after three months and six months of intervention. A statistically significant difference was found before the intervention and 3 and 6 months afterwards (P˂.001). In the control group, no statistically significant difference was found between the pre-intervention and post-intervention (three months (P=.351) and six months (P=.687).Conclusion: The educational intervention based on the stages of behaviour change model showed to be effective in promoting the physical activity of employed women. These findings may benefit health education researchers and practitioners who tend to develop innovative theory-based interventions and strategies to increase the level of physical activity in women.

Abstractwas to assess efficacy of Tadalafil alone versus Tadalafil plus Pentoxifylline in the treatment of erectile dysfunction by using self administered IIEF-5 questionnaire.Two hundred and thirty seven patients presenting with ED at andrology OPD were evaluated for ED by a self administered IIEF (International Index of Erectile Function) questionnaire. Patients were systematically randomized by computer generated random table into two groups groups namely, group A: Tadalafil only group, group B: combination of Tadalafil + Pentoxifyl-line. All the patients were re-assessed by IIEF-5 questionnaire after 8 weeks of medical therapy. Statistical analysis was performed using student’s unpaired t-test, paired t-test, chi square test. p-value < 0.05 was considered statistically significant.Two hundred and thirty seven patients were included in the present study, in group A: 92 patients (78.6%) showed improvement in their IIEF score after 8 weeks of tadalafil treatment. While in group B, overall 104 patients(86.6%) showed improvement after combination of Tadalafil and Pentoxifylline. There was a statistically significant difference of percentage change in IIEF score was seen in group B (group A 90.7±15.2%, group B 95.6±13.4%; p value – 0.014). We found this difference even more statistically significant in patients with severe ED (group A 72.7±47.2%, group B 132.3±54.3%; p value – 0.000). There was no significant difference in between the two groups with regards to occur-rence of side effects.Both tadalafil and combination of Tadalafil + Pentoxifylline improve erectile function in patients of ED. Patients with severe ED showed much significant improvement in erectile function with combination therapy.

Language Environment

There has been a long tradition of concern with the "good language learner" in L2 research. One approach to this topic is to compare the performance of experienced language learners with people who have had less experience with languages. The present study provides comparable data for second- and third-language learners of English. It is hypothesized that L3 learners of English will learn the language with more facility and perhaps with more proficiency than L2 learners of English. The data was collected in two high schools in Amsterdam, where 30 immigrant (L3 learners) and 30 Dutch (L2 learners) students were tested on their knowledge of English with a C-test. They also gave answers to some questions about their personal status and language abilities. The scores were submitted to statistical analysis to test whether or not there was any significant difference between the groups. The statistical test chosen was the T-test for independent groups. The tests were first scored through exact scoring. Once the T-test was applied to both sets of scores (monolinguals and bilinguals), it turned out that the bilinguals scored significantly better than the monolinguals. The answers to the questionnaire were also investigated to find any correlations with the results in the C-test. In addition, the tests were scored through acceptable scoring, which, although no longer significant, still showed the superiority of the immigrant-bilinguals. The hypothesis was confirmed: the assumed superiority of bilinguals in acquiring languages is also found in the immigrant-bilinguals who took part in this study. Despite the negative effects of some of the socio-economic-educational factors affecting the performance of ethnic minority students in Holland, they still have a better aptitude for learning a third language.

Category: Ankle Arthritis; Ankle Introduction/Purpose: There is paucity of literature comparing patient reported outcomes (PROMs) between total joint arthroplasties. There is a need to study the PROMS data to understand outcomes of treatment and factors affecting outcomes. We aimed to to study the PROMs data for total ankle replacement (TAR) to 10 years. To study how PROMS outcomes of TAR compare to total hip replacement (THR) and total knee replacement (TKR) at 10 years Methods: This is a prospective data collection from local hospital joint registry. 10 year follow up data was collected from patients who underwent a total joint replacement (Hip, Knee or ankle), provided informed consent for their data. Patients who refused consent, or had cognitive language problems were not approached for participation in the registry. Self-administered questionnaire data included WOMAC scores, Foot and ankle outcomes scores (FAOS), SF-36 scores and patient satisfaction data. Data was collected at pre-op, 3 years, 5 years and 10 years post operatively. Statistical tests including ANOVA, GLM univariate tests and chi-square tests were used for analysis. Results: There were 119 patients who underwent TAR for the duration of 2006-2009. 74 patients were male (62.18%). Average age of patients was 59.1 yrs. Data was available on 2672 THR and 3520 TKR patients. At 5 years, TAR patients reported lower scores for stiffness, similar outcomes to THR and TKR for mental health score, similar to TKR for ¾ physical domains (p<0.05), but lower satisfaction rates for ADL and recreation when compared to THR (p<0.05). We are currently processing the questionnaires for 10 year mailing returns (completion expected March 2020). Conclusion: The outcomes for TAR were similar to outcomes reported by TKR patients at 10 years but lower than THR. The lower score of TAR was due to stiffness and recreational activity comparing to THR. We aim to present the complete set of results if the abstract is accepted (data completion March 2020).

Introduction: Intracerebral bleeds are the second most common cause of stroke. The initial consciousness level and progressive deterioration and various radiological parameters like hematoma volume, its expansion, mass effect and location has been implicated with poor outcomes of Intracerebral Hematoma (ICH) regardless of the management methods. In this study we aimed to study various clinical and radiological parameters associated with outcome of spontaneous supratentorial ICH. Methods: This prospective study was carried out in 89 patients of spontaneous supratentorial ICH admitted to National Institute of Neurological and Allied Sciences, Nepal in between January 2015 to December 2015 to assess various parameters associated with its outcome. Outcome of the patients were assessed against various clinic-radiological and demographic variables using chi square test and student’s t test respectively for categorical and continuous variables using IBM SPSS 20 software. Results: Glasgow Coma Scale (GCS) (p=0.00), size of hematoma (p=0.034), presence of midline shift (0.000) and presence of intraventricular hematoma (p=0.020) were found to have statistically significant difference when compared in between good and poor outcome group. Conclusion: GCS at admission, size of hematoma, midline shift in cerebral tomography scan (CT scan) and presence of intraventricular hemorrhage (IVH) were significantly associated with outcome of spontaneous Supratentorial ICH.

Complex Phenomena

Abstract Background: The novel virus (COVID-19) pandemic threats the global most since the World War II yet difficult to design effective policy to respond it because widely utilized models only support to predict the future tendency within a narrow time-window. Besides, existing pandemic metrics are sensitive to the detecting policy ( p <0.001), which make them hard to reveal the real infection phenomena, because the fluctuation of these metric values may be an outcome of a suddenly changed detecting policy instead of real infection increase or decrease. Methods: We developed a Benchmark, Amendment and Validation model (BAVM) to make the above complex phenomena clearer, and combined with the hypothesis of potential periodicity of COVID-19 to devote jointly the retreated prediction of pandemic within a broad time-window. Onward, we utilized 113 countries’ epidemic data from January 21, 2020 to August 31, 2020 and detecting policies to carry out our methodology, then validated the results through statistical tests involving chi -square test, one t-test and independent t test. Results: Results exhibit the 4-month of potential periodicity between two adjacent peaks of pandemic ( t =–1.56, p =12.4%). Besides, whether or not the peak emergence has no effect on COVID-19 dynamic trajectory, but the time to firstly peak affects. Meanwhile, uprising the quarantine rate exhibits the earlier expedition towards the first peak emergence (9.7% vs. 6.2%, p =4.1%). On the contrary, the delay of first peak increased the infection rate (0.6% vs. 0.3%, p =1.5%) but also the discharge rate (65% vs. 74%, p =3.8%). Moreover, the indication of the retreated tendency of COVID-19 pandemic is that the next peak should emerge but in fact vanished after one periodicity. Otherwise, the pandemic enters into the next worse phase, typical of high mortality (5% vs. 3.4%, p =5.3%) and low discharge rate (65.8% vs. 74.1%, p =4.2%). Conclusion: To recognize the retreated tendency of this pandemic is quite significant for either the global or the local policy-making, especially in the regular epidemic prevention, control measures and work resumption.
