SPICE Model of Current Polarity-Dependent Piecewise Linear Window Function for Memristors
Authors: KARAKULAK Ertuğrul , MUTLU Reşat
Published: June 2020

Memristor and memristive systems are nonlinear systems. It is important to model them accurately. There are different memristor models and most of the models make use of window functions. In literature, there are various window functions. Recently, a piecewise linear (PWL) window function is used to model a memristor and memristive systems. Such a memristor with a PWL window function lacks a SPICE model. Also, in literature, there is current polarity dependent window functions proposed for memristors to model polarity dependent drift speed within the thin-film memristors. In this study, an alternative current-polarity dependent PWL window function is suggested to model a memristor, a different PWL function one for each current polarity is used, its SPICE model is made in LTSpice and also its simulation results are given. Such a model can be used to model the polarity dependent drift speed within the thin-film memristors.
Deep Learning-Based Architectures for Recognition of Cow Using Cow Nose Image Pattern
Authors: BELLO Rotimi-williams , TALIB Abdullah Zawawi Hj , MOHAMED Ahmad Sufril Azlan Bin
Published: June 2020

Stacked denoising auto-encoder and deep belief network are proposed as methods of deep learning for cow nose image texture feature extraction, and for learning the extracted features for better representation. While stacked denoising auto-encoder is applied for encoding and decoding of the extracted features, a deep belief network is applied for learning the extracted features and representing the cow nose image in feature space. Stacked denoising auto-encoder and deep belief network help in animal biometrics. Biometrics emanated from computer vision and pattern recognition and it plays an important role in the automated animal registration and identification process. Using the visual attributes of cow, and for the fact that the existing visual feature extraction and representation methods are not capable of handling cow recognition; deep belief network and stacked denoising auto-encoder are proposed. An experiment performed under different conditions of identification indicated that deep belief network outshines other methods with approximately 98.99% accuracy. 4000 cow nose images from an existing database of 400 individual cows contribute to the community of research especially in the animal biometrics for identification of individual cow.
Computation of Critical Path Probabilities by Modified PERT
Authors: BETTEMİR Onder
Published: June 2020

Detection of the critical path and the uncertainty of the estimated duration are important for the contactors. PERT and Modified PERT methods can estimate the uncertainty of construction duration. However, probability of a path being critical is not estimated by the aforementioned methods. Monte Carlo simulation is implemented for the detection of probabilities of activities being critical. However, Monte Carlo simulation requires significant computational demand and this method is not suitable for iterative optimization procedure. In this study, Modified PERT method is enhanced by considering every possible path completion combinations. As a result, probability of finishing a path at a certain time and finishing the remaining paths earlier than the corresponding time is computed. This enabled the computation of probability of a path being critical path. For large networks the number of path completion combinations increases which makes the probabilistic computations burdensome. The relationship between the path completion combinations and the statistical intersection operations is derived and a macro code which executes the intersection computations is generated. The algorithm is tested on four sample problems and the results are compared with Monte Carlo simulation. Analysis results interpret that the method is significantly faster than Monte Carlo simulation with similar probability estimations.

Authors: GÜMRÜKÇÜOĞLU Nurhan , BİLGİN SÖKMEN Bahar
Published: June 2020

A series of Schiff base ligands containing 1,2,4-triazole ring were obtained by the addition of aldehydes to the amino compound under mild conditions in 80–82% yields. A reduction of these ligands with sodium borohydride resulted in Schiff base reduction products. New ligands were investigated for their antioxidant activities such as DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2’-azino-bis (3-ethylbenzo-thizoline-6-sulphonic acid) diammonium salt) radical scavenging and reducing power. 1H and 13C-NMR spectra (δ, ppm) were observed on a Varian Mercury 200 MHz spectrophotometer as standard substance using tetramethylsilane Match constants (J values) were given as Hertz. NMR coefficients are truncated as follows: s=singlet, d=dublet, t=triplet, m=multiplet signal. Combustion analysis was performed on a Carlo Erba 1106 elemental analyzer. All the compounds gave C, H, and N analysis results within ±0.6 % of the theoretical values. The IR spectra (υ, cm−1) were viewed with a Perkin-Elmer 1600 FTIR spectrometer in KBr pellets.

The Artistic Reception of the Bible Legend about Cain and Abel in Modern Ukrainian Literature
Authors: Filonenko Natalia
Published: June 2020

The article investigates the reception of the biblical tale of Cain and Abel in the story by A. Zabuzhko Kazka pro kalinovu sopilku (The tale of Cain’s Flute) and the poem by O. Irvanec, Braty (Brothers). The subject of the study were the forms and methods of interpreting traditional motifs and images.

The biblical legend, its folklore and literary interpretations were selected as the basis for the considerations (J.H. Byron, I. Franko). Following an anti-religious trend in the treatment of traditional images, the authors created a postmodern version of Cain - a murderer and victim at the same time. The material of the Cainic tale also served the writers to address the issue of the relationship between extraordinary personalities and the average ones, and the lesser value of the first in the eyes of God. The result of the study are conclusions about the nature of postmodern reinterpretation of literary tradi­tion in the works of A. Zabuzhko and O. Irvanec.

Published: June 2020

Veterinary drug AmixinR, active substance dihydrochloride 2,7-bis[2-(diethylamine)ethoxy]fluorene-9-one (AMX), was tested for its antiviral activity with using of the epizootic relevance for Ukraine the infectious agents of Pseudorabies (PR), Teschovirus encephalomyelitis (TEM), classical swine fever (CSF), porcine reproductive and respiratory syndrome pigs (PRRS), 2nd type of porcine circovirus (PCV-2) and parvovirus infections (PPVI), swine (SIV) and avian influenza viruses (AIV). The influence of this drug on agents of the avian mycoplasmosis (Myc) and pasteurellosis (Past) was also learned. AMX action was tested in the concentrations of 0.5–15 mg/ml, expositions for 0.25–12 hours and at the room temperature. Under these conditions, the inactivation of 20–60% (the highest concentrations more likely) the 1000 infectious units (TCID, ELD or PFU50/ml, respectively) of all viruses was resulted. The 5000 ELD50/ml of the SIV and AIV viruses were inactivated for 5 hours almost totally. Moderate toxicity of AMX was registered in it doses ≥1 mg/ml (P≤0.01) for tube cultures of PK-15 cell line and Marc-145. At the same time AMX doses ≥0.125 mg/ml inhibited by 20–75% of infective activities of agents of the PR, PRRS, PCV-2, PPVI (n=42, P≤0.01) in cell cultures Marc-145 and PK-15, respectively. The toxicity of the drug for 7–9-days-old embryos chickens began to emerge with a concentration of 1.5 mg/ml (n=18, P≤0.01). Its virostatic effect on SIV, AIV and PR agents was manifested in doses ≥0.25 mg/ml (n=24, P≤0.01). AMX was administrated in a single dose of 540 mg ana partes with sunflower oil and showed no toxicity for suckling piglets (n=4, P≤0.01) and 10-days-old chickens (n=10, P≤0.005). At the same time the antibiotic resistant Myc and Past from the blood of chicken infected by natural mixes of these agents, acquire the sensitivity to commercial food antibiotic after 5-days course of treatment by AMX. These data is interpreted the mechanism of therapeutic and preventive action of AMX through direct antivirus activity. The hypothesis of acquires the antibiotic sensitivity by pathogenic bacteria throughout its bacteriophages inhibition is proposed.
Applying Deep-Learning-Based Computer Vision to Wireless Communications: Methodologies,Opportunities, and Challenges
Authors: Tian Yu , pan Gaofeng , Alouini Mohamed-Slim
Published: June 2020

Deep learning (DL) has obtained great success in computer vision (CV) field, and the related techniques have been widely used in security, healthcare, remote sensing, etc. On the other hand, visual data is universal in our daily life, which is easily generated by prevailing but low-cost cameras. Therefore, DL-based CV can be explored to obtain and forecast some useful information about the objects, e.g., the number, locations, distribution, motion, etc. Intuitively, DL-based CV can facilitate and improve the designs of wireless communications, especially in dynamic network scenarios. However, so far, it is rare to see such kind of works in the existing literature. Then, the primary purpose of this article is to introduce ideas of applying DL-based CV in wireless communications to bring some novel degrees of freedom for both theoretical researches and engineering applications. To illustrate how DL-based CV can be applied in wireless communications, an example of using DL-based CV to millimeter wave (mmWave) system is given to realize optimal mmWave multiple-input and multiple-output (MIMO) beamforming in mobile scenarios. In this example, we proposed a framework to predict the future beam indices from the previously-observed beam indices and images of street views by using ResNet, 3-dimensional ResNext, and long short term memory network. Experimental results show that our frameworks can achieve much higher accuracy than the baseline method, and visual data can help significantly improve the performance of MIMO beamforming system. Finally, we discuss the opportunities and challenges of applying DL-based CV in wireless communications.
Operational planning of large-scale energy systems with high share of renewable generation
Authors: Gea Bermúdez Juan , Das Kaushik , Koivisto Matti Juhani , koduvere Hardi
Published: June 2020

This paper proposes a mathematical model to perform optimal operational planning of large-scale energy systems with high share of renewable energy. Furthermore, it analyses the influence of different unit commitment modelling approaches on the operational planning outcomes. The value of co-optimisation of electricity and heating sector is emphasized in this paper. The results show the influence of massive renewable penetration in the energy sector towards 2050, and how this influences generation from other sources such as thermal and hydro. Including unit commitment constraints with integer variables leads to more realistic behaviour of the units, at the cost of increasing considerably the computational time. Relaxing integer variables reduces significantly the computational time, without highly compromising the accuracy of the results. Neglecting the unit commitment constraints leads to inaccurate results in terms of underestimation of costs, curtailment, wind’s and solar PV’s average revenue per energy unit sold, price volatility, and to overestimation of the flexibility of thermal units. Hence, depending on the purpose of the analysis, it is recommended to consider carefully the choice of unit commitment modelling approach and acknowledge the limitations. When the focus is on prices and revenues, using unit commitment constraints with integer variables is preferable.

It is appropriate that this tenth volume of Frontiers be one of the most important publications in the history of education abroad. The number and range of research articles on outcomes of student learning abroad that are presented in this issue would have been hard to imagine when we published the first volume of Frontiers in 1995. On behalf of the editorial board, I want to extend a special thanks to Guest Editor Mick Vande Berg and the Co-Guest Editors Jane Edwards, Hiram Maxim, and Michael Woolf. They have been a delight with which to work, and have done an outstanding job through the stages of manuscript selection, editing and production of this volume. 

Frontiers readers will be please to know that we expect to publish two volumes in 2005, as well as in succeeding years. This is made possible for three reasons. First, we have received additional support from new sponsors, and we thank them and our existing sponsors both for their generosity and for their belief in the mission of Frontiers. We are proud to be supported by academic institutions that are committed to strongly to international education. Second, there is more research being conducted in education abroad than ever before, and as a result, we are receiving more quality manuscripts. We have always believed that the quality of our content matters more than the frequency of our publication, and we are pleased that we now are receiving more high-quality research. Finally, we expect to begin to publish outstanding examples of student research abroad in future volumes as part of our collaboration with the Forum on Education Abroad. We believe that these will be of great interest to our readers and help to document the substantial learning outcomes of study abroad. 

The first volume of Frontiers was published in 1995, and therefore next year marks our tenth anniversary. Our next volume will include a retrospective look at the history of Frontiers as well as how the journal’s evolution has mirrored developments in the field of study abroad. Since our first volume, we have published over 100 articles and essays, and these, we hope, have helped both to inspire and to inform the field of study abroad. 

I want to take this opportunity to extend a special thanks to Dickinson College for continuing to provide substantial institutional support of Frontiers. And, I also want to thank you, our readers, for continuing to cross the frontiers of study abroad in each volume that we publish.

A Necessary Partnership: Study Abroad and Sustainability in Higher Education
Authors: Dvorak Andrea M.W. , Christiansen Lars D. , Fischer Nancy L. , Underhill Joseph B.
Published: June 2020

In this article, we will explore two case studies of programs abroad that seriously engaged both the contradictions and opportunities inherent in the idea of sustainable international education. The first examines environmental politics and ecology in New Zealand and the Cook Islands and the second compares sustainable urban practices in Canada and the United States. Based on the lessons learned from these case studies, we will argue that partnership between internationalization and sustainability efforts is necessary to help institutions of higher learning become both global and “green.” To that effect, we discuss specific and concrete ways to “green” study abroad courses throughout this paper, particularly within the two case studies and in our concluding discussion of strategies for international educators, faculty, and higher education administrators.

Authors: Rutagira Yoweri , Awichi Richard Opaka
Published: June 2020

The main purpose of the study was to investigate the effect of physical distribution management on organizational performance by Rutungu Distributors Ltd, Kampala (U). The study assessed the relationship between order processing and organizational performance in Rutungu Distributors Ltd in an attempt to establish the relationship between storage and organizational performance in the organization. It also sought to find out the relationship between other aspects of inventory management on organizational performance within the company. The research used a case study design approach which was correlational considering both quantitative and qualitative approaches in the data collection, presentation, and analysis. The population of the study was several categories of employees of the company. Findings from the study depicted that there is a positive significant relationship between order processing and organizational performance implying that when a customer submits an order, it is verified to ensure the necessary information is included and processed promptly. Storage and organizational performance; this means that the company can reduce damage through good materials handling. There was a positive significant relationship between inventory control and organizational performance as a result of heavy investment in inventory control practices and procedures. There was also a positive significant relationship between transportation and organizational performance showing that the company has an effective automated transportation system, observes well-coordinated fleet management practices, and also has a good vehicle maintenance policy. The study thus recommends the company to continue reducing the time it takes to get an order to a customer’s premises and to replenish its stores as it is what every company desires, but while faster fulfilment and small order sizes make customers, and store managers happy, faster fulfilment comes at a cost.
On the morphological variation of Rafflesia cantleyi (Rafflesiaceae) on Pulau Tioman, Pahang, Peninsular Malaysia
Authors: Munirah M.Y. Siti , Salamah A. , Razelan M.S.
Published: June 2020

In Peninsular Malaysia, Rafflesia is represented by seven species of which R. kerrii (and R. su-meiae) stands out distinctly from the other five. The other five species, R. azlanii, R. cantleyi, R. parvimaculata, R. sharifah-hapsahiae
and R. tuanku-halimii, are collectively close enough to each other to be referred to as the R. cantleyi complex after its first-described species, R. cantleyi. Pulau Tioman has a population of R. cantleyi, which, because of its island location, is isolated from
the mainland complex. This study was conducted to determine morphological variation in a selected location in Pulau Tioman. Twelve flowers were studied with respect to characteristics such as wart (blotch) pattern on perianth lobes, warts (dots) on upper surface of the diaphragm, shape of
the aperture, shape of processes and types of ramenta. These are the characters that have been used to define species in the R. cantleyi complex. The variation in the local Tioman population was compared with the variation in the R. cantleyi complex on the mainland, which is
about the same magnitude. This supports the idea that R. cantleyi is a single highly polymorphic species and that the species that have been described in the R. cantleyi complex should be reduced to varieties.

An Investigation of Antibacterial Resistance Patterns in Isolated Bacteria from Contaminated Water Samples in Poultry Slaughterhouses
Authors: Tavafi Hadis
Published: June 2020

Nowadays, in the poultry industry, antibiotics are used to treat, prevent, and enhance poultry growth and production efficiency. Their irregular consumption has resulted in the spread of antibiotic-resistant bacteria in this industry. Antibiotic-resistant bacteria in contaminated waters can be transmitted into soil. The purpose of this study was to investigate the antibiotic resistance pattern of bacteria isolated from the water of chicken slaughterhouses around Hamadan (Iran) province. In this study, 20 water samples were collected from four slaughterhouses in Hamadan province (during spring and summer 2019). Initial isolation and identification of the bacteria were performed by pour plate culture and biochemical tests. The disc diffusion method was applied to investigate the resistance pattern. This study presents 109 screened isolates. Of these, 57.8% E.coli, 35.7% Salmonella spp., and 6.42% Klebsiella spp. were detected. Antibiograms of isolates showed that in E.coli, 23.09% were resistant to four types of the antibiotic tetracycline, amoxicillin, gentamicin, and chloramphenicol, 76.19% had only one type of antibiotic. Antibiotics for Salmonella spp. showed that 35.9% were resistant to tetracycline, gentamicin, and chloramphenicol, 64.10% to only one type of antibiotic. Also, in Klebsiella spp., 85.71% were sensitive to antibiotics, and only 14.28% were resistant to tetracycline. Conclusion: The results showed that the rate of multiple antibiotic resistance is relatively high, and contaminated water has a high potential for soil contamination. Therefore, resistant bacteria become more stable in the environment, and the health of the environment will be endangered. Therefore, it is necessary to study the antimicrobial resistance patterns of bacteria to study and maintain the health of the environment.
Psychological empowerment as a predictor of quality in training
Authors: Gomes Isabel , Coimbra Joaquim Luis , Menezes Isabel
Published: June 2020

This paper analyses the model of Adult Education and Training (AET) in Portugal, taking into consideration the two available reports on this recent domain, which reveal that empowerment is a prescriptive goal. However, this construct continues to be ill defined.The empowerment theory suggested by Zimmerman and colleagues, particularly the psychological empowerment construct, shows enough consistency with the AET model to consider that it might contribute to the management of quality in training.These reports also state the urge for better, more inclusive and more reliable measures in assessing quality in training. Contributions of the empowerment theory to this matter are discussed, attempting to analyze and operationalize it in this specific domain.
Haydegger and Sartr: I, the Other and People in the context of the problem of education
Authors: ВОЛКОВ Олександр
Published: June 2020

The article compares the interpretation of the relationship between I, the Other and People in the existentialism of Heidegger and Sartre. For Heidegger, the Other is a henchman, an area that is determined by the execution of a case. Care that is pre-ontological and therefore impossible to consider. Orientation is the identification of relationships between places, which is why a person must maintain a distance. Its necessity is explained by the fact that I am on the premises of People. The impotence of the Self is due to the fact that it is impossible to determine what People are. As a result, each person seeks to be invisible, hide in the middle. Unlike Heidegger, Sartre explores the Self as an independent entity, which is in dialectic relations with Another. Therefore, it depends on the teacher as Another how I will be the pupil. The influence of Another is explained by a look that clarifies: who is who. That is why the teacher has the opportunity to shame the children. With it, a child has the opportunity to see his uniqueness and uniqueness, in other words, become a person.

Potential impact of mammal defaunation on the early regeneration of a large-seeded palm in the Brazilian Atlantic Forest
Authors: Meiga Ana Y. Y. , Christianini Alexander V.
Published: June 2020

Defaunation, the decline in animal species and populations, is biased towards large-bodied animals that have unique roles as dispersers of large seeds. However, it is speculated that these roles may still be performed by smaller animals, such as small mammals like rodents and marsupials, that thrive in defaunated sites. We investigated if small mammals can disperse the large-seeded palm Attalea dubia. We performed the study in a well-conserved Atlantic Forest remnant in southeast Brazil that still harbours large mammals, such as tapirs. Focal observations showed that capuchin-monkeys consumed the mesocarp of the fruits and dropped the seeds beneath the plant crown thereafter. Mammals preyed on ca. 1% and removed ca. 15% of the fallen fruit/seed and deposited them up to 15 m away. Amongst them, small mammals (< 1 kg), such as the squirrel Guerlinguetus brasiliensis and non-identified nocturnal Sigmodontinae, as well as the marsupial Philander frenatus performed the bulk of interactions. Dispersal enhances recruitment, but the short distances of seed removal did not match the current spatial distribution of palm seedlings and juveniles. Recaching rates of hoarded seeds were small (2%) and unlikely to increase distances of seed dispersal achieved. Short distances of dispersal would increase plant clumpiness and negative density-dependent effects with time. Although small mammals can provide legitimate dispersal, they cannot fully replace larger frugivorous mammals and maintain long-distance seed dispersal that feeds plant metapopulation dynamics and seed gene flow.

Authors: Lin Lin
Published: June 2020

There are several defects with the current evaluation strategy for educational competitiveness of universities, namely, the lack of a well-established evaluation system and the complexity of evaluation factors. To overcome these defects, this paper analyzes the key factors affecting the educational competitiveness of universities, and establishes an evaluation system covering such three aspects as basic input, progress and output. On this basis, an evaluation model was created to assess the educational competitiveness of universities, in the light of multiple factors on varied levels. Overall, our evaluation system and its model can effectively achieve the multi-factor evaluation of the educational competitiveness of universities, providing a good solution to complex system decision-making problems.

Variations in anatomy of the obturator nerve are important to surgeons and anesthesiologists performing surgical procedures in the pelvic cavity, medial thigh and groin regions. They are also helpful for radiologists who interpret computerized imaging and anesthesiologists who perform local anesthesia. This study aimed to describe the anatomical variations and distribution of obturator nerve. The cadavers were examined bilaterally for origin to its final distribution and the variations and normal features of obturator nerve. Sixty-seven limbs sides (34 right and 33 left sides) were studied for variation in origin and distribution of obturator nerve. From which 88.1% arises from L2, L3 and L4 and; 11.9% from L3 and L4 spinal nerves. In 23.9%, 44.8% and 31.3% of specimens the bifurcation levels of obturator nerve were determined to be intrapelvic, within the obturator canal and extrapelvic, respectively. The anterior branch subdivided into two, three and four subdivisions in 9%, 65.7% and 25.4% of the specimens, respectively, while the posterior branch provided two subdivisions in 65.7% and three subdivisions in 34.3% of the specimens. Hip articular branch arose from common obturator nerve in 67.2% to provide sensory innervation to the hip joint. Accessory obturator nerve was not observed at all in this study.

Published: June 2020

This study investigated the effect of hyperthermia on the gonads of the pups of Wistar rats following maternal exposure to brief hyperthermia during pregnancy. Twenty-five pregnant adult female Wistar rats were randomly selected into two groups: Group A (Control) which consisted of 10 female rats and Group B (Experimental) which had 15 female rats. The pregnant dams in the experimental group were exposed to brief hyperthermia for 15 minutes twice daily at 8.00am and 4pm on gestational day (GD) 12-18. The pups produced by the rats were weighed, examined and sacrificed at 35days of post-natal life. Recorded were the microscopic appearances of the gonads while the luminal diameter and thickness of the gonadal vessels were measured and recorded. Data was analysed, mean and standard deviation were generated with student t-test, and p< 0.05 was taken as significant. Maternal exposure to brief hyperthermia during pregnancy significantly reduced the birth weight of the pups in Group B (3.86 ± 0.26g) compared to Group A (4.71 ± 0.18g). The luminal diameters of the testicular and ovarian arteries of the pups in Group B were significantly increased whereas the gonadal vascular arterial wall thicknesses were significantly reduced in comparison with the Group A. Histological examination of the gonads revealed fewer cell population with degeneration and damage to the germinal epithelium of the gonads of the pups in Group B which was more severe in the testes. Maternal exposure to brief hyperthermia during pregnancy has deleterious effects and subsequent destruction of the gonads of pups of Wistar rats and this may interfere with fertility of the pups later.

This study investigated the effects of aqueous extract of fruit pulp of Adansonia digitata on albino rats infected with Trypanosoma brucei brucei. Acute toxicity test was conducted on the extract and then analysed for some phytoconstituents. Thirty-five adult rats were divided into seven groups of five rats each. Group A were the non-infected control group while groups B, C, D, E, F and G were inoculated with 1x 106 trypanosomes per 100 g body weight (BW). At day 6 post infection (6 PI), groups C and D were treated with diminazene aceturate and vitamin C at dose rates of 3.5 mg/kg BW intra peritonealy once and 200 mg/kg BW orally for 3 days respectively, while groups E, F, G were orally treated for 3 days with 40, 80, and 160 mg/kg BW of the extract respectively. The rats were monitored for parasitaemia, PCV and body weight. The LD50 of the extract was greater than 9000 mg/kg. The phytochemical analysis revealed 3.51% flavonoid, 0.07% alkaloid, 0.10% saponin and 0.03.0% oxalate in the extract. While there was progressive increase in parasitaemia from day 6 PI in groups E and F throughout the study, parasitaemia decreases and was completely cleared by day 8 and 11 PI in groups C and G respectively. PCV of group A was not significantly different (p>0.05) from that of F and G. There was significant difference (p<0.05) in the PCV of Group A and that of groups B and C and highly significantly different (p<0.01) with that of D and E. Significant (p<0.05) body weight increase of rats in groups D, E, F and G at day 10 PI was observed. Thus, fruit pulp of A. digitata at a dose of 9000 mg/kg was not toxic to rats, and contains active compounds with potential In vivo anti-trypanosoma activity.

Published: June 2020

The experience during African swine fever (ASF) virus outbreak can be devastating. This study aimed to assess the knowledge, attitude and practise among pig farmers to avoiding resurgence of ASF outbreaks in Oyo and Ogun States of Nigeria where ASF outbreaks had been earlier reported. Non participatory observations and participatory interviews using pre-tested structured questionnaire were conducted in 2016 among 92 consenting pig farms post-ASF outbreak. The study showed that one in two of pig farms studied had suffered from ASF outbreak before. Meanwhile, several bio-security breaches that facilitate ASF and other infectious agents spread were still maintained including ‘farm restocking with ASF survivor pigs’ (61.5%; 32/52), ‘boar lending among farms for breeding purposes without examination’ (54.3%; 50/92), ‘extensive system and semi-intensive pig management’ (21.7%; 20/92), ‘farm attendants sharing among pig farms’ (19.6%; 18/92), ‘farm equipment/ implements/ facilities sharing among farms’ (22.8%; 21/92), selling of pig carcass (9.8%; 9/92), ‘carcass disposal in the bush’ (19.6%; 18/92). In this study we found out that management and bio-security activities in the pig farms studied were still poor and could place them at high risk of infection and repeated disease outbreaks in the future. The study suggests that pig farmers had not learnt from the previous ASF outbreaks. Therefore, proper sensitization on ASF epidemiology, public health significance and socioeconomic impact should be carried out. This study calls for swift action to prevent future calamities in pig production facilities in the study areas.
