Aiming at triggering in-depth research of the problem of Premature Ovarian Insufficiency (POI) in Slovenia, we assessed the regional differences in POI incidence emphasising the relationship with social and physical environmental factors at the population level using a mapping approach. The differences in POI incidence between regions were tested by goodness-of-fit chi-square test, while Pearson correlation coefficient was used to assess the ecological relationship between POI incidence and selected environmental indicators. Significant indicators were mapped. The results showed highly significant interregional differences in POI incidence (p<0.001). Statistically significant ecological relationships were observed between POI incidence and prevalence of active smoking (p=0.001), passive smoking (p=0.017) and consumption of vitamins (p=0.008). The results could be used in diminishing interregional differences in POI. It was concluded that mapping is an effective tool in public health research, especially in triggering new activities.

 Hemoglobin level is a continuous variable. So, it follows some theoretical probability distribution Normal, Log-normal, Gamma and Weibull distribution having two parameters. There is low variation in observed and expected frequency of Normal distribution in bar diagram. Similarly, calculated value of chi-square test (goodness of fit) is observed which is lower in Normal distribution. Furthermore, plot of PDFof Normal distribution covers larger area of histogram than all of other distribution. Hence Normal distribution is the best fit to predict the hemoglobin level in future.

Café as an establishment primarily sells refreshing drinks, snacks, and light meals, with coffee being their flagship product. This type of business is steadily multiplying around the city of Tagbilaran, Bohol, Philippines. Customers have linked to business success as well as customer satisfaction and customer loyalty. This study was implemented to analyze the role of customers’ satisfaction in gaining customers’ loyalty, specifically among purposively selected cafés. The quantitative method of research approach was used with the aid of questionnaires. The data gathered were statistically treated making use of frequency, composite means, weighted mean, chi-square test, and Pearson correlation coefficients. The respondents included 210 customers from the purposively selected cafés. Results showed respondents to be very satisfied (VS) for the Product; for the price; for the place; for the service quality; and moderately satisfied (MS) for promotion. Results further showed that there is a significant degree of relationship between customer satisfaction and customer loyalty.

Background and Aim: The Watish sheep is a strain of desert sheep of smaller size compared to other desert sheep ecotypes, and there is anecdotal evidence that it is endowed with high litter size. The present study was designed for screening for polymorphisms in the known fecundity genes (bone morphogenetic protein receptor type 1B A<G in exon 6, bone morphogenetic protein 15 (BMP15) (FecXB, FecXG, FecXH, and FecXI) in exon2, growth differentiation factor 9 (GDF9) – G1 in exon1 and G8 in exon2 and PRLG<A in intron2) and their association with litter size in Watish. Materials and Methods: The study involved 156 Watish ewes of 2-6 years of age, along with data on litter size in the first, second, and third parity from Sinnar state and contiguous Blue Nile State. Genomic DNA was isolated and genotyped using polymerase chain reaction-restriction fragment length polymorphism. Allele and genotype frequencies were calculated by direct counting. Chi-square test for goodness of fit was performed for agreement with Hardy-Weinberg expectations and association testing. Results: The results demonstrated that all individuals were non-carriers for the target mutations of FecB, BMP15 (FecXB, FecXH, and FecXI), and GDF9-G8. With regard to the GDF9-G1 gene, the genotypic frequencies were 0.07% (G+) and 0.93% (++), in FecXG gene they were 0.993% (++) and 0.006% (B+), in PRL gene 0.516(++), 0.347(B+), and 0.137(BB). The Chi-square test showed a non-significant association between ewe's type of birth and the detected mutations genotypes. Conclusion: These results preliminarily indicated that GDF9-G1, BMP15 (FecXG), and PRL genes might have had some contribution for improving litter size in Watish Sudanese sheep. However, further studies using larger samples are needed to detect the effects of those mutations on Watish sheep litter size.

Objective: Brucellosis is a zoonotic disease seen widely around the world. Although many aspects and treatment of this disease is well known, peritoneal involvement and ascites is not well established so far. Material and Methods: This study retrospectively enrolled 346 adult patients (aged >17 years) with acute Brucellosis attending Hepatology Clinic, Van Yuzuncu Yil University, between April 2013 and May 2016. Characteristics of those with and without ascites were analyzed using Pearson correlation coefficients and Chi-Square test in SPSS software system. Results: Of the 346 cases, 20 (5, 7%) had ascites. Those with ascites had significantly higher transaminase, cholestatic enzyme and amylase levels compared to those without ascites. Conclusions: We conclude that acute Brucella infection can lead to a unique low gradient ascites probably resulting from pancreatic leakage followed by peritoneal accumulation of serum proteins.

Abstract The purpose of this study was to assess the level of digitization of Educational Technology Centres for teaching electrical and electronics technology in Colleges of Education in North Eastern Nigeria in order to provide information that will help solve problems of incompetence of public school students in Information and Communication Technology (ICT). The study, guided by two research questions and two hypotheses was conducted in six Colleges of Education in North Eastern Nigeria using descriptive survey research design. The sample of the study was 50 comprising of 15 non-teaching Educational Technology Centres staff and 35 Electrical and Electronics Technology lecturers from five colleges of education in North Eastern Nigeria. Checklist containing 103 expected digital facilities based on National Commission for Colleges of Education (NCCE) minimum standard for Educational Technology Facilities in Colleges of Education in North Eastern Nigeria was used as instrument for data collection. Respondents were required to fill in observed facilities in the required column. Arithmetic percentage and Chi–square test of goodness-of-fit and were used determine the extent of digitization of the Educational Technology Centres in Colleges of Education in North Eastern Nigeria. Findings of the study revealed among others that analog technologies has higher number of frequency counts compared to digital technologies, hence there was low digitization of hardware facilities in Educational Technology Centres in Colleges of Education in North Eastern Nigeria. The study therefore concluded that Educational Technology Centres in Colleges of Education in North Eastern Nigeria were not digitized for instructional purposes; therefore, Government should digitize Educational Technology Centres in Colleges of Education in North Eastern Nigeria by adequately providing both digital hard and soft ware facilities.
