Authors: Kuku Olaotan Oladele , Adeniyi Samuel Olufemi
Published: December 2020

There had been consistent concern and reports on the low achievement of learners with hearing impairment in mathematics with mixed observations about the ability and influence of learning environment of learners with hearing impairment. However, there are consensus that impactful teaching effort could aid in stimulating innovative approaches in teaching and learning of mathematics of learners particularly among learners with hearing impairment. This study seeks to appraise the impact of gamification and experiential learning on achievement in mathematics among learners with hearing impairment in Lagos State, Nigeria. The study population comprised learners with hearing impairment in Lagos State. Purposive and simple random sampling were used to select sample of 24 learners. The research design used was quasi-experimental pretest posttest control group. Mathematics Knowledge Check (MKC) was used to collect data and the data collected were analyzed using mean, standard deviation, mean difference and analysis of covariance (ANCOVA). The hypotheses were tested at 0.05 level of significance. The study found out that achievement in Mathematics improves as a result of exposing learners with hearing impairment to gamification and experiential methods of instruction. Besides, the study observed that the two interventions were of benefit to male and female learners with hearing impairment. The employment of gamification and experiential instructional strategy was recommended for mathematics lessons of learners with hearing impairment.

A basic result from the theory of quasirandom graphs, due to Andrew Thomason, is that if is a graph with vertices and density , and if the number of 4-cycles in is approximately , then resembles a random graph of the same density. In particular, between any two sets and of vertices the number of edges is approximately . (Here, “approximately” means "to within a small fraction of , so the statement is non-trivial only for sets and that are not too small.)

An even function is a function with a graph that is symmetric with respect to the y-axis or the line x = 0. In this paper, we will introduce a more general function of the even function, we call it as symmetry function with respect to the line x = a, which is a function whose graph is symmetric with respect to the line x = a. This paper discusses the properties of the symmetry function with respect to the line x = a, which is derived from the pre-existing properties of the even function. Some of the results obtained above, the linear combination of the symmetry functions with respect to the line x = a is a symmetry function with respect to the line x = a and the composition of any function with a symmety function with respect to the line x = a is a symmetry function with respect to the line x = a. Keywords: Even function, a symmetry function with respect to the line x=a, symmetric graph

Published: December 2020

Let G = (V, E) be a simple and connected graph. For each x ∈ V(G), it is associated with a vector pair (a, b), denoted by S x , corresponding to subset S = {s1 , s2 , ... , s k } ⊆ V(G), with a = (d(x, s1 ), d(x, s2 ), ... , d(x, s k )) and b = (δ(x, s1 ), δ(x, s2 ), ... , δ(x, s k )). d(v, s) is the length of shortest path from vertex v to s, and δ(v, s) is the length of the furthest path from vertex v to s. The set S is called the bi-resolving set in G if S x ≠ S y for any two distinct vertices x, y ∈ V(G). The bi- metric dimension of graph G, denoted by β b (G), is the minimum cardinality of the bi-resolving set in graph G. In this study we analyze bi-metric dimension in the antiprism graph (A n ). From the analysis that has been done, it is obtained the result that bi-metric dimension of graph A n , β b (A n ) is 3. Keywords: Antiprism graph, bi-metric dimension, bi-resolving set. .

Samarinda is one of the big city in Kalimantan since it is a capital city of East Kalimantan Province. Its population is about 988,943 in 2015, but only 28.62 percent of the whole households were applying clean and healthy living behavior. To encourage this behavior to the society, it needs some health promotions to be introduced to them. In order to know the pattern of clean and healthy behaving households with respect to time, so this research is aimed to perform a mathematical model of the implementation of clean and healthy living behavior which involves health promotion. Runge-Kutta is the used model to solve this model. The result informs that the rate of change of the households which implement a clean and healthy life, called as good people, increases for all sub-districts in Samarinda City. In contrast, households that do not know and do not behave clean and healthy life, called as bad people, are reduced because of the promotion.

Published: December 2020

This research attempts to study the determinants of third party funds on the Islamic banking in Indonesia with eight years of research from published journals in Indonesia. To reach the above objectives, investigation to check the relationship between promotion cost, inflation, GDP, interest rate, number of offices, and equivalent rate to third party funds on the Islamic banking in Indonesia is conducted. This research applies the meta-analysis technique to a sample of 34 articles with time variation from 2010-2018. The articles used are selected studies from Sinta Journal and Google Scholar databases. This research shows that promotion cost, number of offices, and equivalent rate have a significant correlation with third party funds on the Islamic banking in Indonesia. Meanwhile, inflation, GDP, and interest rate have no significant correlation with third party funds on the Islamic banking in Indonesia. The Findings from this study imply that if Islamic banks in Indonesia wish to enhance their third party fund, they must focus on internal indicators (promotion cost, number of offices, and equivalent rate), rather than looking at macro indicators.

Published: December 2020

This study aims to examine the effect of Contribution Income Investment Results and Claim Expenses on Sharia Life Insurance Profits in Indonesia for the 2012-2019 period. This research is a quantitative study with secondary data in the form of Islamic financial reports and the sample selection using purposive sampling. The amount of data is 13 companies with eight years of observation to obtain 104 observational data which are sampled in this study. The technique used is panel data regression analysis technique, with analysis of hypothesis testing, namely the t test and F test. The results show that contribution income partially affects the profit of Islamic life insurance, the investment results also affects the profit of Islamic life insurance, if the fund invested are large, the investment returns will be large so that the profit will be high. Furthermore, claim expense partially affects the profit of sharia life insurance, the claims will reduce the amount of funds to be invested by the company, at the end it reduces the company’s profit. Based on F test, all variables simultaneously influence the profit of Islamic life insurance. The suggestion is that, in order to increase the profitability of Islamic insurance, the company Islamic insurance needs to consider the investment process, also to increase the underwriter analysis to mitigate the excess of expenses from claims.

Published: December 2020

Waqf performance, as part of Islamic social finance is determined by, among others,  willingness of society to donate their assets into waqf. Ability to understand determinants of the willingness may contribute to more optimum waqf assets accumulation and management. This study aims to investigate the effect of attitudes, subjective norms, perceived behavioral control, and knowledge in influencing the willingness of waqif to donate through the Airlangga University Social Fund Management Center (PUSPAS). This research is a quantitative study using multiple regression analysis. Data for this study is obtained from 98 respondents. The study results imply that there was no significant simultaneous influence in the variables of attitudes, subjective norms, behavioral control, and knowledge of waqif willingness to represent in PUSPAS. The attitude and knowledge variables are variables that have a significant influence partially. In contrast, the subjective norm variables and behavioral control have a partially insignificant impact on the intention of waqf to represent.

This study investigates how family lineage descent groups influence the intergenerational transmission of education for the cohorts of 1940-1989 in the Democratic Republic of Congo (DRC). The study applies both transition matrix and intergenerational persistence (IGP) methods, using the father's years of schooling as a proxy for parental education. The findings suggest a pronounced steady persistence in education for the estimated mean regression coefficient over a period of 49 years. Moreover, results by gender indicate that intergenerational persistence in education has significantly decreased for males in recent cohorts but slightly increased for females. Furthermore, findings suggest that intergenerational persistence has been decreasing in matrilineal descent groups in recent cohorts, while increasing for the patrilineal descent groups. The study gives a good sense of the relationship between family lineage descent and intergenerational transmission of education in DRC. In addition, it indicates that there is both substantial upward and downward intergenerational education mobility in the country.

Respiratory tract infections (influenza, acute respiratory infections (ARIs), community-acquired pneumonia, etc.) pose a serious threat to organized groups (including military personnel, cadets, students of military universities, and schools). The most common complication of ARI is community-acquired pneumonia, severe forms of which may result in an unfavorable outcome. The use of some drugs, such as Carmolis ensures a 2.0–3.8 times reduction in the incidence of ARIs in organized groups and a 2.3–3.0 times reduction in the incidence of community-acquired pneumonia. Carmolis has a pronounced non-specific protective effect and increases resistance to respiratory tract infections by promoting nonspecific resistance of the organism. This prevents significant economic damage and reduces the number of complications and poor outcomes.

Influenza and acute respiratory viral infections (ARVI) remain a global health problem worldwide, and therefore the search for effective means of prevention and treatment of these diseases is extremely urgent. Objective. To evaluate the therapeutic efficacy and safety of a drug form of recombinant human IFN alpha-2b in combination with a complex of antioxidants (Viferon®-suppositories) in children with ARVI. Patients and methods. Clinical and laboratory studies were conducted in 100 children (toddlers up to 3 years old), hospitalized in St. Olga's children hospital No 4 with a diagnosis of influenza or ARVI. The etiology of diseases was established using serological methods and immunofluorescence analysis; the immune and interferon status was determined. VIFERON®-suppositories were used rectally daily in age-related dosages. The effectiveness of therapy was evaluated by comparative analysis of disease symptoms, as well as laboratory indicators – immune and interferon status. Results. The use of VIFERON® – suppositories contributed to reducing intoxication and catarrhal symptoms, speeding up the recovery time of patients. After the treatment, the children's ability to produce IFN-α and – γ, as well, as sIgA content in nasal secretions, increased, but there was no marked enhancement in serum IL-1β, IL-8 levels, whereas the children in the control group and in 30% of cases occurred to change them. The use of the medicine did not cause any complaints in patients and staff. Conclusion. Data from clinical and laboratory studies of children hospitalized for ARVI, whose therapy included the VIFERON® – suppositories, indicate a significant therapeutic effect of this medicine and restoration of the immune and interferon defense systems of patients.

Objective. To assess epidemiological characteristics of purulent septic infections (PSIs) in the intensive care unit (ICU) of a burn center. Patients and methods. In this retrospective epidemiological study, we analyzed medical records of 399 patients with burn injuries and the results of laboratory testing (2,572 samples). The majority of ICU patients were men aged 30–39 years. Almost half of the patients were workers. Burns were primarily caused by an open flame and were mainly received at home. Of note, 45.4% of patients who had burns caused by an open flame also had respiratory tract lesions. More than half of the patients had deep burns. A total of 18.6% of patients (95% CI 14.8–22.7) died. Results. The incidence of PSIs in the ICU of the burn center was 533,8‰ (95% CI 483.5–583.6), which is 2.5 times higher than that in the official statistics (210,1‰ (95% CI 182.5–239.9)). More than half of PSIs (50.2% (95% CI 43.3–57.1)) were burn wound infections. Conclusion. The following factors were found to be associated with an increased risk of PSIs: burn area >40%, burn severity index >30, SOFA score >4, deep burns, surgery, stay in the ICU for >10 days, artificial ventilation for >1 day, and placement of a central venous catheter or an urinary catheter for >1 day. Most frequently, PSIs were caused by non-fermenting gram-negative bacteria such as Pseudomonas аeruginosa and Acinetobacter baumannii.

Published: December 2020

In this work, the additive manufacturing process selective laser melting is analysed with the aim of realising a complex piece for aerospace applications. In particular, the effect of the manufacturing process and of the following thermal treatments on the dimensions of the workpiece is evaluated. The study is based on a hybrid approach including a simulation of the whole manufacturing process by advanced software packages and the dimensional measurements of the realised pieces taken by a coordinate measuring machine (CMM). The integrated use of simulation and measurements is carried out with the aim of validating the simulation results and of identifying the operational limits of both approaches; this analysis is based on metrological evaluation of the results of both the simulation and the tests, taking into account the uncertainty of the data. In addition, the main causes of uncertainty for the simulation activity and the experimental data have been identified, and the effects of some of them have also been experimentally evaluated. Based on the experimental validation, the simulation seems to predict the absolute displacement of the supports of the piece in a satisfactory way, while it is unable, in the actual configuration, to assess the conformity of the surface to its very tight shape tolerances. Conformity assessment of the surface should be carried out by CMM measurement. Integrated use of simulation and experimental results is expected to strongly improve the accuracy of simulation results for the effective and accurate design and control of the additive manufacturing process, including dimensional control and thermal treatments to mitigate induced thermal stresses.

Published: December 2020

Background

Self-harm and drinking were both serious problems in adolescents and many studies presented evidence of their association. However, gender differences in this association was seldom deeply discussed. Our study was aimed to evaluate the prevalence of self-harm and explore its association with drinking behaviors by gender and investigate the extent to which the gender differences exist in the association between self-harm and drinking.

Methods

A total of 32362 students in grades 7 to 12 were anonymously surveyed and included in our study using two-stage, stratified probability proportion sampling in Beijing, China. Self-harm, drinking behaviors and other basic information were obtained from anonymous questionnaire. Demographic variables, self-harm as well as drinking behaviors were analyzed with Chi-square test and Gamma test between genders and the gender differences in this association was analyzed by log-binomial regression.

Results

The total prevalence of self-harm was 13.7% with no significant gender difference (=0.352, P=0.553). The prevalence of self-harm decreased with age in girls (G=-0.163, P<0.001). Self-harm was associated with drinking behaviors in both boys and girls. The Log-binomial regression demonstrated that girls in 16-19 years were at lower risk of self-harm than girls in 12-15 years while this association was weaker in boys (1.493 vs 1.128). The higher OR for self-harm was found among girls with early drinking experiences compared with boys (2.565 vs 1.863). Girls who ever drunk (2.211 vs 1.636), were currently drinking (3.400 vs 2.122) and binged drinking (6.357 vs 3.924) were of greater risk for self-harm than boys.

Conclusion

Self-harm has significant positive association with drinking among high school students and girls with drinking behaviors were at higher risk of suffering self-harm. Identifying adolescents’ drinking behaviors is of vital importance to self-harm prevention and special attention should be focused on younger girls.

Published: December 2020

Background: The role of viruses as a cause of breast cancer (BC) has been significantly investigated in recent years. Human papillomavirus (HPV) has been detected in invasive breast carcinomas, while most studies have only focused on the detection of viral DNA, we aimed to examine the prevalence and genotypes of HPV among Iranian BC patients. Methods: We collected and analyzed 70 Formalin-Fixed Paraffin-Embedded (FFPE) blocks including 59 BC samples, and 11 benign breast lesions as control from Iranian patients using nested PCR. Real-time PCR utilized as a confirming test to nested PCR findings. Genotyping of HPV positive samples was performed, the samples were also subjected to a multiplex PCR to detect herpes simplex-1 (HSV-1), herpes simplex-2 (HSV-2), varicella zoster virus (VZV), and cytomegalovirus (CMV) in BC.Results: Papillomavirus DNA was present in 7 of 59 BC samples (11.8%); while none was detected in control samples. The most prevalent type was HPV18, followed by HPV 6. All HPV positive patients had high tumor grades (II/ III) with a histologic diagnosis of ductal carcinoma. The patient age range was 33 to 73 years with a median of 51 years. Most of HPV positive patients had low levels of education. HPV16 was not detected. Also, 5 of 59 BC specimens (8.47%), were positive for HSV-1.Conclusions: Our results suggest a carcinogenesis role for High-risk HPVs in breast tumors. Our findings of HSV-1 and low-risk HPVs in BCs may propose a cancer-causing role for them. Further large-scale studies are warranted to assess the significance of our findings.

Authors: Freihat Sultan
Published: December 2020

The current study aims at examining the role of transformational leadership in paving the way for well-built reengineering of marketing strategies within the healthcare sector in Jordan. Depending on a quantitative approach, 312 questionnaires were distributed to individuals within hospitals: 105 questionnaires – healthcare centers, 75 questionnaires – outpatient clinics, and 33 questionnaires – general medicine clinics in Jordan. The study results indicated as a start better employment of transformational leadership within hospitals compared to clinics and healthcare centers, which can be attributed to the size and capacity of the healthcare institution. The study also indicated an influence of transformational leadership in paving the way for reengineering of marketing strategies within the healthcare sector in Jordan attributed to all transformational leadership characteristics. Among these characteristics, it appeared that the most influential transformational leadership characteristic was “individualized consideration”, scoring a Beta value of 0.421. This meant that the individualized consideration that transformational leadership has can nurture creativity and innovation among individuals to use their talents, experiences, and skills to present new and novel approaches to managing the business. This individualized consideration helps manage the change approach that may appear within the reengineering process and cooperate with employees to embrace such change. The study recommended following transformational leadership as an approach within the organization to manage change and arm employees with a suitable leadership style that can prepare the environment for a well-prepared reengineering of marketing strategies.
Agricultural Extension System in Bihar, India: An Overview

Published: December 2020

Agricultural extension system plays a crucial role in increasing agricultural productivity and farm income, strengthening food security, improving rural livelihoods, and promoting agriculture as an engine of rural economic growth. In India, a Central Department of Agriculture was established after the Orissa famine during 1866. Department of Agriculture in Bihar was established in 1912 after separation of Bihar from Bengal. After independence, several programmes like IADP, IAAP, HYVP etc were implemented in Bihar, which fetched good results. Later on, Training and Visit approach of extension was also implemented which was subsequently replaced by NATP. Currently, pluralistic extension services in Bihar is prevailing which includes central and state Government agencies, ICAR, KVKs, SAUs, NGOs and private sector organizations. Despite all the efforts, transfer of technology programmes are yet to achieve desired success. Duplication of extension services is being observed as many agencies work in same set of selected villages. Recently, using Agriculture Road Map of Bihar, Government has launched several agricultural development programmes for transfer of modern agricultural technology, which may likely to improve access of farmers to modern agricultural technology. To make extension more pragmatic, some of the activities including supply of quality inputs and market linkage of the produce should be the part of core extension programme.

A field experiment was conducted at BCKV during Rabi, 2018-19 and 2019-20 to study the effect of Zn, Fe and B foliar spray on phenology and thermal indices of popular lentil variety, Moitree (WBL 77) under different sowing condition [1st week of November (normal) and 1st week of December (late)]. Delay in sowing of crop from November to December reduced the crop duration by 11.4 days (113.4 days vs 101.7 days). The variation in mean daily temperature and bright sunshine hour among two sowing dates resulted in varied accumulated Growing Degree Days (GDD), Helio Thermal Units (HTU) as well as Photo Thermal Unit (PTU). It was found that different dates of sowing have a larger impact on change in phenology of the crop and thus affect various thermal indices. Foliar spraying of micronutrients viz., B + Fe @ 0.5% produced significantly higher seed and stover yield of 1438 kg ha-1 and 3981 kg ha-1 respectively, which were 86.26% and 27.0% more than that obtained from the control treatment (772 and 3134 kg ha-1). The study conducted revealed that along with optimum date of sowing, spraying micronutrients especially a mixture of B+Fe@0.5 % and B+Zn+Fe@0.5 % could also bring in change of phenology to some extent. This may help in better accumulation of photosynthate hence, improving the yield responses of lentil.

Processed potatoes are an important nutritional component of our diets and the demand for processed potato products are increasing. To evaluate the variety suitable for processing, ten potato cultivars procured from Agricultural Research Station, Hassan, Karnataka were studied for their physical, biochemical and functional parameters. Significant differences in the physical parameters were observed. Sprouting and shrinkage were observed in some cultivars after storage for three months at 10-15°C. Kufri Chipsona-1 and Atlantic cultivar had the highest dry matter content, which is an important quality measure suitable for processing. Proximate composition of all the cultivars varied significantly. Phenol content ranged from 5.74 to 26.79 mg/100g, with the lowest in Frito Lay-1533 and Atlantic cultivar. TSS, water absorption index, bulk density, gelatinization and emulsion capacity vary significantly among the cultivars. Kufri Chipsona-3 contained the highest starch (81.1%) and total soluble solids (7.12°Brix). Based on the low phenol content, Atlantic and Frito Lay-1533 were processed and studied for their functional parameters. Water absorption and gelatinization capacity of Atlantic and Frito Lay-1533 were higher in the processed than in the unprocessed sample and differ significantly.
