Published: March 2023

One of the challenges facing agricultural sector development in Nigeria is inadequate financing by the government and financial institutions. This poor agricultural funding has an impact on economic activities. Thus, this study investigated the connection between agricultural funding and economic performance in Cross Rivers State's Obudu Local Government Area (LGA). The survey study methodology was employed, and a questionnaire was used as its primary data source, combined with a stratified sample technique. The targeted population was restricted to farmers and agriculturalists in the study area. Descriptive statistics, such as frequency and percentages tables, were calculated, and the data gathered from the questionnaire were compiled, computed, and analysed. The results of hypothesis testing showed a relationship between agricultural finance and economic performance, as well as a connection between agricultural credit schemes and agricultural sector expansion, using analysis of variance (ANOVA) as the statistical technique. They also showed that credit programmes for agricultural finance encourage the expansion of the agricultural sector, which improves economic performance, as manifested in economic growth and development. The study recommends, firstly, that the government release grants to farmers at regular intervals to support their activities. Secondly, it is necessary to raise the level and size of agricultural loans through the reduction of interest rates to allow for more economic development in the country. The government should implement an effective and efficient supervisory framework to monitor interest rate regulation within the agricultural loan policy.

Published: March 2023

This study aims to design a sustainable and comprehensive economic enterprise development program for communities in Cabanatuan City through an asset-based community development (ABCD) approach. The concept consists of two phases: capacity building and company development. Community capacity building focuses on enabling all community members to acquire the skills and competencies they need to take more responsibility for their own lives and contribute to inclusive local development. The key components of the capacity development phase are community planning, community organization, community need assessment, gap analysis, project programming, project execution, project monitoring, and evaluation. Community planning involves choosing the most viable community business ventures based on six economic factors: market, capital, raw materials, service providers, support infrastructure, and appropriate technology. Enterprise development is a low-cost, straightforward training strategy for aiding entrepreneurs and microbusiness owners with business planning and expansion. This component is further subdivided into enterprise growth, local government assistance, developing industry connections, enterprise marketing and promotion, enterprise performance monitoring and evaluation, and impact assessment. Acquiring economic aptitude is essential for the survival of Cabanatuan City's citizens and provides them with a sense of self-worth and communal pride.

Authors: Rusanova Daria A.
Published: March 2023

Aim to evaluate the metric parameters of the upper dentition in patients with a stable result of orthodontic treatment of anomalies in the position of the crowns of the upper canines in the long-term follow-up period.
Material and methods. We conducted an open study on a sample of patients after orthodontic treatment using clinical and instrumental methods. We analyzed 126 clinical cases of patients aged from 18 to 44 years with completed orthodontic treatment of abnormal position of the crowns of the maxillary canines with satisfactory aesthetic and functional results. The duration of the retention period ranged from 5 to 10 years. 75 patients met the inclusion criteria for the study.
Results. The study showed that the biometric parameters of the dental arches after the end of orthodontic treatment did not always correspond to the individual norm of a patient. An increase in the transversal size of the upper dentition in the region of the premolars was determined in 44 patients (58.6%), a slight narrowing in the region of the first molars in 34 patients (45.4%), lengthening or shortening of the anterior part of the dental arch in 32 (42.7%) and 23 (30.6%) patients, respectively. With the proportionality of the mesio-distal dimensions of the incisors of the upper and lower jaws (Tonn's Index 1.340.03) and the relative macrodontia of the canines of the lower jaw (anterior Bolton's ratio 81.03.2%), the symmetrical position of the crowns of canines of the upper jaw and the value of the rotational angle of 28.02.1corresponded to the functionally optimal results of orthodontic treatment.
Conclusion. Aesthetically satisfactory and functionally stable results of orthodontic treatment of patients with anomalies in the position of the crowns of the maxillary canines during the retention period correspond to the following biometric parameters of the upper dental arch and / or their combination: lengthening of the anterior region, an increase in the transversal size in the region of the first premolars and a decrease in the region of the first molars in maintaining the individual norm of intercanine width. The stability of the results of orthodontic treatment in patients with anomalies in the position of the canines and the shape and / or size of the dental arches is ensured by the maximum possible leveling of violations of the anatomical and topographic norms of the teeth position.

Aim to study the microbiome of the placenta in full-term pregnancy with premature rupture of the membranes (PROM) in comparison with the intact membranes.
Material and methods. The study was conducted on the basis of Samara City Clinical Hospital N 1 named after N.I. Pirogov and involved 43 pregnant women at 37-41 weeks of gestation subject to elective cesarean section. The patients were divided in two groups: the main group included 24 women with PROM, the control group was formed with 19 women with intact fetal membranes. The placental tissues were taken for the real-time PCR-test for the following microorganisms: Lactobacillus spp., Enterobacteriaceae, Streptococcus spp., Staphylococcus spp., Gardnerella vaginalis / Prevotella bivia / Porphyromonas spp., Eubacterium spp., Sneathia spp. / Leptotrihia spp. / Fusobacterium spp., Megasphaera spp. / Veillonella spp. / Dialister spp., Lachnobacterium spp. / Clostridium spp., Mobiluncus spp. / Corynebacterium spp., Peptostreptococcus spp., Atopobium vaginae, Mycoplasma hominis, Ureaplasma (urealyticum + parvum), Candida spp., Mycoplasma genitalium.
Results. At the end of physiological full-term pregnancy, the bacterial population was detected in 66.7% of placentas in the main group, total bacterial count Ме 103,2 Q1:Q3 0,0 103,4 GE/sample; and in 78.9% of the placentas in the control group, total bacterial count Ме 103,3 Q1:Q3 103,1 103,5 GE/sample. The main representatives of the identified microorganisms were Enterobacteriaceae spp. (Me 103,2 GE/sample for PROM and Me 103,2 GE/sample for intact amniotic sac (p0.05)). Lactobacillus spp. were determined in the placenta only in the PROM group in 8.3% of patients. The presence of Lactobacillus spp. in the tissues of the placenta is typical only for patients with PROM. Microorganisms not identified by the Femoflor-16 test were found in 50% of patients with PROM, Me 102,1 GE/sample, and in 63.2% of patients with an intact fetal bladder, Me 103,2 GE/sample, (p = 0.09). No correlation was found between PROM incidents and the characteristics of the placental microbiota.
Conclusion. In case of physiologically proceeding full-term pregnancy, it is possible to detect using the real-time PCM test a bacterial population represented by the Enterobacteriaceae spp., while in cases of PROM, Lactobacillus spp. and anaerobic vaginal flora were also detected in placental samples.

The evolution of HCI education does not take place in a vacuum, nor is it only controlled by the academics and practitioners close to its core. In this paper we reflect on the causes of change in the HCI curriculum and consider what has been lost and found during these changes. Taking inspiration from both the theme of the workshop and the cultural richness of the workshop location we consider the value of change, and contrast the needs for preservation of valued artifacts with the need for artifacts that reflect the modern age; streamlined and efficient. Our paper concludes with a manifesto for the modern HCI age.

Teaching Gameplay Design is Teaching Interaction Design
Authors: Lundgren Sus
Published: March 2023

This paper describes the benefits of integrating gameplay design in interaction design teaching since this allows students to practice designing for unusual situations, considering ethic and aesthetic issues as well as issues of use and abuse, often all in the same project. Some examples – ranging from a three week group project to a half day exercise – are described, each together with aims and noted learning outcomes related to interaction design, as well as with a general discussion. In addition, a few student projects are described together with learning outcomes. Finally the pros and cons of this approach are discussed, and educators willing to try it, but inexperienced in games, are getting some useful information on what to look into.
Observations on Peer Evaluation using Clickers
Authors: Räihä Kari-Jouko , Ovaska Saila , Ferro David
Published: March 2023

Clickers and paper forms were used in a senior level HCI class for peer evaluation of student project presentations. Scores given by teachers and students were compared and subjective opinions of students analyzed. Students gave higher scores than teachers and scarcely used the higher and lower ends of the scale. The medium used for evaluation did not have a significant effect on the scores. Students preferred the clickers to paper because of their novelty, possibility of immediate feedback, and easier preservation of privacy. Concerns were raised over lack of individual feedback in the clicker device and limited added value over traditional pen and paper.
Advanced Interaction for Information Visualization
Authors: Fekete Jean Daniel
Published: March 2023

Information Visualization (InfoVis) is a Research field dedicated to the design and evaluation of visual representations and interactions to explore and understand large data set. Until recently, the focus of InfoVis has been more on the representations and less on the interactions. However, several new interactive techniques have been published in the last years, opening perspectives for HCI practitioners. We describe the work at INRIA Saclay – Ile-de- France, linking traditional HCI interaction research with InfoVis interaction research. We present our latest techniques for navigating large information spaces: OrthoZoom for one dimensional (1D), MeÌlange for 2D, ScatterDice for high- dimensional spaces, ControlTree for large trees and Topology- aware navigation for networks. We outline their applicability in HCI problems that are not traditionally viewed as InfoVis in the hope that they will be experimented and adopted in standard interfaces and, more importantly, to emphasize the fact that interaction design for large information spaces is required for our complex user interfaces.

Creating an interactive application based on pre-existing functionalities poses a number of novel issues in the design process. We discuss a method, associated with a new model-based language and a supporting tool, which aims to address such issues in multi-device contexts. One specific aspect of this method is the possibility of supporting composition of user interfaces associated with different services. In addition, the possibility to specify dynamic user interfaces, Web services accesses and scripts allows designers to declaratively describe Rich Internet Applications as well.
A Workload Manager Architecture for the Monitoring of Drivers’ Cognitive Impairment
Authors: Cardillo Daniela , Calefato Caterina , Minin Luca , Montanari Roberto
Published: March 2023

This paper presents the architecture of a software system able to assess the cognitive effort of a driver by monitoring the interaction between the driver and the steering wheel; this system is called WL Manager (WLM). The advantage of a Workload Manager System based on the steering dynamic is that of being not invasive in comparison to other workload measures, in particular physiological (heart rate, eye movements, etc…) which are considered by the literature more reliable than the other indirect measures. Furthermore, the dynamic of the steering wheel can be read from the onboard electronic units available for innovative steering systems like Steer-By-Wire devices (i.e. a steering wheel fully electronically controlled and without mechanical link with the front wheel); then, the implementation of a WLM system on a real car is a realizable project.

Comparison of second mesiobuccal canal prevalence of maxillary molar teeth by gender and age in a Turkish subpopulation: A cone-beam computed tomography study
Authors: Akay Ahmet , Öz Hasan , Adıgüzel Özkan , Erkan Akay Seda
Published: March 2023

Aim: The purpose of this study is to examine the distribution of second mesiobuccal (MB2) canal frequency according to age and gender in the maxillary molars of individuals in South-eastern Anatolia, Turkey, using cone-beam computed tomography (CBCT). It also seeks to inform dentists who perform root canal treatments about the prevalence of additional canals that affect the success of treatments.
Methods: 300 patients who had already had CBCT images taken were grouped by gender and age. A total of 1,034 maxillary molar teeth were evaluated in the axial section. The chi-square test was used to evaluate the morphological differences between different age groups and genders.
Results: The total frequency of MB2 canals was found to be 44.4% in 300 people (42.5% in women; 47.2% in men). In addition, the frequency of MB2 canals was 59.2% (n = 506) in maxillary first molars and 30.4% (n = 528) in maxillary second molars. On the basis of the right and left jaws, the incidence of MB2 canals was 44.2% in the right jaw and 44.9% in the left jaw. No statistically significant differences were found between gender and age.
Conclusion: It is concluded that using CBCT will increase the detection of the presence of additional canals, increasing dentists’ success rates in performing root canal treatments. Furthermore, it has been observed that using new technologies and spending more time in the detection of MB2 canals will increase the success of root canal treatments in maxillary molar teeth.

Does a sloped neck implant design facilitate All-on-4 surgeries? A three-dimensional finite element analysis
Authors: Toprak Mehmet Emin
Published: March 2023

Aim: In the treatment of edentulous resorbed mandibles using All-on-4 concept, the distal part of posteriorly tilted implants with a conventional flat neck design is usually embedded in the bone, which may lead to improper installation or positioning of angled multiunit abutments. Bone trimming from the distal area, where the implant neck is embedded in the bone, is typically necessary to avoid this complication. This study aimed to evaluate the biomechanical behavior of a sloped marginal neck configuration of implant posteriorly tilted at 30° in edentulous mandibles using a three-dimensional finite element analysis (FEA).
Methodology: The sloped neck implants were posteriorly tilted at 30° without any further operation in the edentulous mandibular model designed using the FEA. The tilted conventional flat neck implants were placed at the same length, diameter, and angle, and 2 mm2 of bone was trimmed from the distal area. Similar multiunit abutments, two conventional flat neck implants axially placed on the anterior side, titanium frameworks, and acrylic resin prosthetic dentures were created for both models. The biomechanical behaviors of the models were evaluated by applying a foodstuff force of 50 N to the incisors, 100 N to the premolars, and 150 N to the molar cantilever.
Results: The von Mises stress value of the sloped neck implants (158.489 MPa) was lower than that of the conventional flat neck implants (177.208 MPa). Both the maximum and minimum principal stress values ​​in the surrounding cortical and cancellous bones were within the acceptable physiological limits.
Conclusion: Sloped neck implants can be placed easily and are less invasive than conventional flat neck implants; thus, they can be a treatment alternative that can facilitate the All-on-4 concept.

The aim of the study has been to evaluate the active internationalization of the dairy sector in Poland during the Covid-19 pandemic. The restrictions that were system-wise imposed globally since early 2020 created new conditions for the functioning of markets, also in the international dimension. As a result, production, logistic and consumption processes were considerably altered. The research subject was the dairy sector, which is an important link in the Polish food economy. The study covered years 2020-2021, showing the changes relative to the previous time periods. The literature perusal and analysis of the statistical data concerning the Polish foreign trade enabled us to confirm the hypothesis that food markets, including the dairy sector, are an important anchor of the Polish economy in times of crisis. The strong position of the Polish dairy products on international markets was maintained and even strengthened at the end of the researched period. A relatively high degree of the geographical diversification of the internationalization of the dairy sector compared to the whole agricultural and food sector was observed. It can be expected that the business solutions developed during the pandemic will additionally reinforce enterprises from the dairy sector in the future.

A biological study was conducted in newly hatched (200) broiler chicks (44.06 ± 2.18 g) divided into 5 treatments each consisting of 4 replicates with 10 birds in each, were fed with control (basal diet), T1 (canthaxanthin (CAN) and apocarotenoid (APO) at 25 ppm each), T2 (CAN 50 and APO 25 ppm), T3 (CAN 25 and APO 50 ppm) and T4 (50 ppm each). Birds were reared for 42 days under standard managemental conditions during hot-dry summer season with THI 84.66. Bi-weekly body weight (BW) and feed intake (FI) were recorded. Blood samples were collected and shank colour was measured at 28th and 42nd days of age. Cell mediated immune response and carcass characteristics were studied at 28 and 42 days of age respectively. Overall BW and body weight gain (BWG) were significantly higher in birds fed with combination of 25 ppm CAN and APO compared to other groups. BWG was significantly higher in T1 than other treatment and control groups at finisher phase. Feed conversion efficiency (FCE) was significantly improved in T1 and T2 than all other groups. Dietary inclusion of synthetic carotenoids significantly increased the aspartate transaminase, phosphorus and total protein but reduced cholesterol and triglyceride level in blood plasma compared to unsupplemented dietary treatment group. Higher pigmentation was observed in T1 than the other combinations of carotenoids. It could be concluded that feeding combination of synthetic carotenoids (CAN and APO) at 25 ppm each exhibited positive effect on performance, blood parameters and pigmentation in heat stressed broilers.

The aim was to compare predictive performance of SVM-based predictors constructed using different kernel functions (radial, sigmoid, linear and polynomial) in different genetic architectures of a trait (number of QTL, distribution of QTL effects) and heritability levels. To this end, a genome comprised of five chromosomes, oneMorgan each, was simulated on which 10,000 bi-allelic single nucleotide polymorphisms (SNP) were distributed.Cross validation employing a grid search was used to tune the meta-parameters of each kernel function. Pearson’scorrelation between the true and predicted genomic breeding values (rp,t) and mean squared error of predictedgenomic breeding values (MSEp) were used, respectively, as measures of the predictive accuracy and the overallfit. Meta-parameter optimization had a significant effect on predictive performance of SVM-based predictors insuch a way that by using improper meta-parameters, the predictive power of models decreased significantly. In allmodels, the accuracy of prediction increased following increase in heritability and decrease in the number ofQTLs. In most of scenarios, radial- and sigmoid-based SVM predictors outperformed polynomial and linear models.The linear-and polynomial-based SVM had lower rp,t and higher MSEp and, therefore, were not recommended forgenomic selection. The prediction accuracy of radial and sigmoid models was approximately the same in most ofthe studied scenarios; however, considering all pros and cons of radial and sigmoid kernels, radial kernel wasrecommended as the best kernel function for constructing SVM. All of studied SVM-based predictors were efficientusers of time and memory.

Prolactin is one of the potential genes which mediates seasonal cues entraining reproductive and hair follicle growth cycles. Seasonal changes in levels of prolactin hormone mediate the patterns of de-iodinase enzyme activity which influence the follicular activity and thereby may affect Cashmere fibre growth and moult. To study polymorphism of the prolactin gene and associate it with fibre production and quality, Changthangi goat 196 bp fragment of prolactin gene Exon-V region was amplified and restriction digested with ECO 241(BanII) and in the study three genotypes were observed. These different genotypes were confirmed by DNA sequencing. The frequencies for the observed genotypes A1A1, A2A2, A1A2 were 0.214, 0.291 and 0.495 respectively. The distribution of the genotypes within the Changthangi goat population studied herein did not deviate from the Hardy Weinberg equilibrium. The mean genetic variability parameters for the gene analyzed were 0.4970 (heterozygosity value), 0.3735 (PIC value), 1.9880 (Effective allele number) and 0.6901 (Shannon index I) . The polymorphism observed in the gene showed a non-significant association (P>0.05) with Cashmere quality traits. The results obtained here in, because of low sample size, demand further investigation with sufficiently large number of samples.

The objective of the present study was to investigate the association of polymorphic variants of keratin-associatedprotein (KAP) 1.3 gene with wool traits in Rambouillet sheep. Genomic DNA was isolated from blood samples of 100 Rambouillet sheep. A 598 bp KAP 1.3 gene segment was amplified by PCR using ovine specific primers. One SNP was confirmed by sequencing, which was C264T nucleotide transition mutation. Restriction Fragment Length Polymorphism (RFLP) using Bsr I restriction enzyme revealed two alleles A and B with 0.645 and 0.355 allele frequencies, respectively. Genotypic frequencies were 0.41 for AA, 0.47 for AB and 0.12 for BB genotypes. The X2 test value for KAP 1.3 gene was non-significant revealing that the population under study was in Hardy Weinber Equilibrium (HWE). Significant differences for CWY and highly significant differences for FD, SL, WC and GFW were observed between the least squares means of sex. Males showed higher level of production for CWY (56.91±0.26%) and GFW (2.53±0.09 kg); whereas, females were found to be superior in FD (21.74±0.11 μ), SL (6.07±0.15 cm) and WC (62.80±0.29). The least squares means of various genotypes for GFW differed significantly. Highest GFW production was recorded for BB genotype (2.47±0.13 kg) followed by AB genotype (2.05±0.07 kg) and least by AA genotypes (1.62±0.08 kg). These results suggested that polymorphisms in the KAP 1.3 gene might be a potential molecular marker for genetic selection for GFW in Rambouillet sheep.

The present study assessed the nutrient composition, in vitro digestibility and methane production potential of the commonly fed feed resources of North Western Himalayan region. The feed resources were collected from different parts of North Western Himalayan region and dried at 60Â°C until constant weight and used for further analysis. The in vitro digestibility and methane production potential were determined using the in vitro gas production technique. The results indicated that in concentrates, cereal grains had significantly high ME value, high digestibility,low methane production potential and low methane energy loss as compared to brans. In roughages, tree fodders, had significantly high digestibility, high ME value, low methane production potential and low methane energy loss as compared to grasses and crop residues. In this study, there was strong negative correlation between OM and methane production; and strong positive correlation between ash, lignin, ADF, cellulose and NDF contents and methane production in concentrates. In contrast to concentrates, in roughages strong positive relationship wasobserved between OM contents and methane emission. Positive correlations between NDF, HC, cellulose and methane production; and negative relationship between methane production and lignin, ash and EE contents were also observed in roughages. Regression equations developed for predicting methane production showed high level of predictability for concentrates as compared to roughages. The data on nutrient composition, methane production potential reported for various feedstuffs in this study could be utilized judiciously in formulating low methaneemission diets for feeding ruminants in the region.

The present study was conducted to determine the apparent total tract digestibility (ATTD) and apparent ilealdigestibility (AID) of dry matter (DM), gross energy (GE), crude protein (CP), and amino acids (AA) in soybeanmeal (SBM), solvent-extracted canola meal (SECM) and corn distiller dried grain with solubles (corn-DDGS) forgrowing pigs. Three growing barrows (Landrace × Yorkshire × Duroc, 33.37±1.11 kg of BW) fitted with a simpleT-cannula at the distal ileum were fed 31.61% SBM, 39.33% SECM, or 52.17% corn-DDGS as the sole proteinsource diets in a 3 × 3 Latin square design with 3 diets and 3 periods. The ATTD and AID for DM, CP, and GE inSBM were greater than in corn-DDGS. Similarly, the ATTD and AID of CP in SBM were greater than in SECM.SBM had greater AID for phenylalanine, cystine, proline, and tyrosine than corn-DDGS. SBM had greater AID forlysine, methionine, threonine, valine, aspartic acid, glutamic acid, glycine, serine, total essential AA, total nonessential AA, and total AA than SECM and corn-DDGS. SECM had greater AID for lysine, aspartic acid, glycine,and tyrosine, but less glutamic acid than corn-DDGS. In conclusion, the results imply that SBM had greater ATTDand AID of DM and GE than corn-DDGS. The values of AID of N and the majority of AA were higher in SBM thanin SECM and corn-DDGS.
