Efek Perlindungan Mangsa dan Daya Dukung Variabel pada Sistem Mangsa-Pemangsa dengan Fungsi Respon Beddington-DeAngelis
Authors: Hanifah Aisyiah Kholifatul , Abadi Abadi
Published: February 2024

Several species in the world have experienced extinction. To save species from extinction, a system needs to be formulated, one of which is protecting prey. Changes in physical and biological processes also have a role in the environment, namely resulting in dynamically changing carrying capacity. The rate of prey consumption by the average predator, i.e. the response function is also important in the system formulation. In this study, a prey-predator system was constructed with a Beddington-DeAngelis response function that considers prey protection and variable carrying capacity as well as a predation process that takes into account the predator population. In this research, the equilibrium point for prey-predator extinction, predator extinction, and coexistence was determined and then continued to analyze its stability. With a large prey protection value, the predator extinction equilibrium point is asymptotically stable and the coexistence equilibrium point is asymptotically stable, if and only if within a certain range of prey protection parameter values. In addition, simulations were carried out and it was concluded that at certain prey protection values, changes occurred in the stability of the system which depended on the limits of its carrying capacity.

Text analytics can be applied in education to gain insights into student learning, teacher performance, and educational trends by analysing various forms of text-based data such as student essays, social media posts, and educational resources. While the need for teacher preparation and training is identified, specific solutions or effective strategies for equipping educators with the skills and knowledge to integrate graphic visualizations into their teaching practices might be underexplored. This Scientometrics study used PRISMA approach (Preferred Reporting Items for Systematic Review and Meta-Analysis) Using R tool. Scopus databases that were relevant to the research topic, and its standardized procedures ensured comprehensiveness and replicability. The study found 85 articles using the PRISMA approach from the Scopus database, with 98.82% being articles and 1.18% from conference proceedings. The number of articles published increased in 2022, with 33 articles, compared to 22 articles in 2020. The total number of cited papers was 70, with a total citation of 969. This indicates an increase in research related to graphic visualization in education due to technological advancements. The citation per cited paper was 119. Besides, the study identifies the top 10 countries that have conducted research in graphic visualization, with the United States leading with 19 studies followed by China with 12 and Spain with 8. The top three subject areas in the current research trends are Computer Science education with 78 publications, Engineering education with 33, and Social Science education with 14. Other fields related to language and linguistics are also being given special attention.

Published: February 2024

Machine Learning (ML) systems are now widely used across various fields such as hiring, healthcare, and criminal justice, but they are prone to unfairness and discrimination, which can have serious consequences for individuals and society. Although various fairness testing methods have been developed to tackle this issue, they lack the mechanism to continuously monitor ML system behaviour at runtime. In this study, a runtime verification tool called BiasTrap is proposed to detect and prevent discrimination in ML systems. The tool combines data augmentation and bias detection components to create and analyse instances with different sensitive attributes, enabling the detection of discriminatory behaviour in the ML model. The simulation results demonstrate that BiasTrap can effectively detect discriminatory behaviour in ML models trained on different datasets using various algorithms. Therefore, BiasTrap is a valuable tool for ensuring fairness in ML systems in real-time.

Published: February 2024

Corruption, which is generally defined as the abuse of authority for personal benefit, is not a recent phenomenon and has become a major issue in almost all countries throughout the world. Indeed, a high level of corruption increases bank non-performing loans which in turn reduces profitability and intensifies the fragility of the banking industry. Given the adverse impacts, corruption has been used as one of the factors in bank performance evaluation. As research on corruption-bank performance with machine learning techniques is rarely reported in the literature, this paper presents the empirical comparison of different machine learning algorithms for classifying bank profitability. Besides machine learning performance comparisons, this paper presents the analysis of machine learning features importance to justify the effect of corruption factor in the different machine learning algorithms for classifying bank profitability. The results indicated that all the tested machine learning algorithms present a good ability of classifying bank profitability at accuracy percentages above 70% but corruption index has contributed very minimal effect to the machine learning performances. The framework of this research is highly reproducible to be extended with a more in-depth analysis, particularly on the bank profitability factors as well as on the machine learning algorithms.

Authors: Nur Syazwani Zulkifli  , Siti Nur Aliaa Roslan
Published: February 2024

Technology Acceptance Model (TAM) is essential to the field of Building Information Modelling (BIM) implementation especially in the construction industry since the government mandate, it has become the key towards this perception as an obstacle of success. While innumerable studies focus on the way contractors, consultants and stakeholder acceptance towards BIM, therefore, it becomes a method for improvisation. However, up until present, limitation have been found for government staffs and perceptions regarding this manner. As to affirm, the government as well as its organization are the backbone of BIM utilization for every country. Research has shown that BIM is also influenced by the one who holds the authority by government mandating its usage strategies, and that representations are generally more effective than appeals from other users. Thus, this study aims and focuses on examines the emerging role of government organizations in the context of perceptions and acceptance towards BIM as well as the readiness of government mandate in facing challenges for Building Information Modelling (BIM) implementation in Malaysia. In this study, an online survey was distributed to government staffs that currently uses BIM across Malaysia. The obtained data were analyzed by statistical tools of IBM SPSS 28 to empirically test the correlation and impact of the proposed variable. The results showed that the TAM for BIM and well-structured government mandate will affect the challenges in BIM implementation. This paper has been organised in the following way. Starts with introduction, literature review, methodology, results and discussions. Finished with conclusions accordingly. Additionally, acceptance of BIM technology would initiate of minimizing the challenges faced by government staffs in Malaysia that involve in BIM. Good obtained values for TAM and government mandate variables in explanatory power, concluded this study. Further research is needed in this area of study to identify well-planned roadmap and proper guideline for government staffs in strengthening the effectiveness of BIM implementation in the future.
Security and Safety in Cyber-Physical System (CPS): An Inclusive Threat Model
Authors: Mardiana Mohamad Noor  , Ali Selamat  , Nurulakmar Abu Husain  , Ondrej Krejcar
Published: February 2024

A Cyber-Physical System (CPS) is a combination of computational algorithms and physical processes that are integrated together. Cyber-Physical Systems (CPS) integrate computer and communication capabilities with the monitoring and management of physical parts, establishing a mutually beneficial interaction between the cyber and physical components. Industrial Control System (ICS) is one example of CPS which integrates the physical (OT) and cyber domains (IT), which makes them more vulnerable to attacks. Two essential characteristics of Cyber-Physical Systems (CPS) are safety and security. Threat models are methods for identifying, analysing, and proposing security control countermeasures for threats and their capabilities. However, the threat model methods which are used for the traditional IT systems are not sufficient as they do not include the physical interactions, consequences and impacts to the safety aspects in the Operational Technology (OT). On the other hand, a risk assessment analyses attack scenario, examines cybersecurity from the attacker's point of view, and gives cost-benefit data to support the expenditure on security measures. This study proposes an inclusive attacker’s centric threat model and pro-active risk assessment model for CPS using Mamdani Fuzzy Inference System (FIS). The outcomes of the threat model prove that the lateral propagation of the threat is possible and threat may also propagate from the CPS assets to the IT segment. The risk assessment by using FIS shown that the safety and security risk for the CPS is significant and calculated as medium level. Hence, the risk factors that are considered in calculating the overall risk for a CPS need to be immediately addressed and mitigated.

Enhanced Scalar Multiplication Algorithm over Prime Field Using Elliptic Net
Authors: Norliana Muslim  , Faridah Yunos  , Zuren Razali  , Nur Idalisa Norddin
Published: February 2024

Scalar multiplication in elliptic curve cryptography is the most expensive and time-consuming operation. The elliptic curve cryptography attracted interest due to the development of modern technology since it could offer the equivalent high level of security with a reduced length of key. Therefore, improving elliptic curve scalar multiplication performance has always been the primary goal of cryptography. In this paper, a novel scalar multiplication algorithm based on the modified double and double add via elliptic net with Karatsuba method was proposed in order to enhance the efficiency of scalar multiplication. In the experimental results, the elliptic net equivalence sequence was applied to the Twisted Edwards curve together with safe curves of numsp384t1 and numsp512t1. At the point operational level, the proposed method reduced the cost of multiplication by 46.15% and 42.30% for double and double add, respectively, when compared to elliptic net using eight blocks method. The proposed double lowered the multiplication cost by 12.5% and the squaring cost by 20% when compared to elliptic net using ten temporary variables method. Following this, proposed double add cost reductions of 6.25% and 20% were obtained to multiplication and squaring. At the field operational level, in comparison to the binary method, the eight-block elliptic net method, and the elliptic net method with ten temporary variables for the 384 bits scenario, the developed scalar multiplication algorithm obtained cost reductions of 57.6%, 31.3%, and 13.2%, respectively. On 512 bits with similar comparison, the designed algorithm exhibited better performance by averages 59.2%, 31.0% and 13.2%. The results signified that the designed algorithm over prime field performed better at the point and field operational levels with larger scalar bit size.

Published: February 2024

Research on symbolic meaning in the Qur'an surah al-Baqarah/2: 115, al-A'raf 7:57 and al-Anfal/8: 17 is based on the belief that the Qur'an can only be understood just textually, you don't need to understand it contextually. After examining in depth the tafsir of al-Azhar and Wahbah az-Zuhaili, it was found that understanding the Qur'an is not only textual but also contextual, one of which is by understanding the symbolic meaning of the Qur'an. This research aims to reveal the symbolic meaning of the Al-Qur'an (comparative study of tafsir al-Azhar and tafsir al-Munir). To answer the question above, the researcher conducted research using a research library or literature based on reviewing tafsir books and related books, while the method used in this research was muqaran tafsir. The primary data source in this research is the Koran surah al-Baqarah/2: 115, al-A'raf 7:57 and al-Anfal/8: 17 using the tafsir al-Azhar and tafsir al-Munir. Secondary data is in the form of books, interpretations of articles and other works related to this research. The results of this research are that it can be understood in Surah al-Baqarah/2: 115 the meaning of Allah who put fear into the hearts of the Prophet's enemies, namely by conveying pasih that far away could hit them, especially when facing the Prophet at close range they would definitely be defeated by the prophet and his companions. The voice of al-A'raf 7:57 explains that the Qur'an is a source of faith that will revive the hearts of the dead and it is also with faith that the hearts of living people can understand the holy verses of the Qur'an. As for surah al-Anfal/8: 17, it can be understood that if a person faces to pray then there is his Qibla, when he does not know the direction of the Qibla for prayer or if a person does not know the direction of the Qibla then Allah will be pleased with him when he faces the Qibla. the.

Making Tourism Sustainable? Environment and Resort Tourism in Negril, Jamaica, 1970s–2002
Authors: ALTINK HENRICE
Published: February 2024

Based on newspaper accounts, official documents and reports by international donors, this article sets out the growing awareness about the environmental impact of resort tourism in Jamaica and action proposed and undertaken to put tourism on a more sustainable path, from the 1970s till the adoption of a Masterplan for Sustainable Tourism Development in 2002. Through a case study of the resort town of Negril, it will argue that the Master Plan was the culmination of action and lobbying by industry stakeholders and environmental groups, a global and regional shift towards sustainable tourism and pressure from international donors. It will also make the case that, throughout the period, the Jamaican government struggled to balance the economic and environmental sustainability of tourism because of the centrality of tourism to the national economy and its limited fiscal space.

Authors: Aleksiev Vladimir , Yavorov Boyko , Stoev Hristo , Dimov Rosen , Kostov Gancho , Vazhev Zaprin
Published: February 2024

Colorectal carcinoma (CRC) is the third most common cancer and the fourth deadliest. Despite recent advances in screening methods and preoperative imaging techniques, the threat of colorectal cancer remains at an all-time high. Moreover, even after curative treatment, disease recurrence occurs in up to 40% of all cases. However, half of patients with recurrent disease do not register any distant metastases. Therefore, much effort should be expended in identifying and evaluating these patients, as many of them are suitable candidates for en bloc resections with perioperative chemoradiation. In fact, it has recently been found that overall survival benefits greatly from extended resections, provided that free margins are achieved intraoperatively. In this case report, we will present a case of locally advanced recurrent colorectal cancer invading the aortoiliac axis and our approach to achieving a R0 resection.
Significant role of pyocyanin and exotoxin A in the pathogenesis of Pseudomonas aeruginosa isolated from hospitalized patients
Authors: Panahi Zahra , Owrang Mina , Goli Hamid Reza
Published: February 2024

Aim: Due to the importance of exotoxin A and pyocyanin in the pathogenicity of this bacterium, we decided to evaluate the prevalence of genes encoding these virulence factors in clinical isolates of P. aeruginosa.

Materials and methods: In this study, 100 clinical isolates were collected and identified by conventional biochemical tests. The ability to produce pyocyanin was determined by culture in a specific liquid medium (GSNB) at 37°C. The DNAs of the bacteria were extracted by the SDS method and a PCR test was performed to identify the exoA, phzA1B1C1D1E1F1G1, phzM, and phzS genes.

Results: In this study, 90 isolates were pyocyanin-producing in phenotypic test. Also, 96%, 98%, 92%, and 96% of the isolates carried exoA, phzM, phzS, and phzA1B1C1D1E1F1G1 genes, respectively. Interestingly, 2 isolates lacking the exoA gene did not have the phzM and phzS genes at the same time, but the other 2 isolates carrying all three gene loci required for pyocyanin synthesis. Also, among the strains that lacked the ability to produce pyocyanin, 2 isolates concurrently lacked the phzS and phzA1B1C1D1E1F1G1 genes and 2 isolates simultaneously lacked the phzM and phzS genes, while the 2 isolates did not carry only the phzS gene. The other 2 isolates did not contain only phzA1B1C1D1E1F1G1 operon.

Conclusion: The presence of the phzA1B1C1D1E1F1G1 operon, along with the phzM and phzS genes, plays a significant role in the production of pyocyanin pigment. However, the high prevalence of exoA gene in this study indicates the importance of this factor for vaccine designing.
Effects of body mass index on urinary lithogenic factors in urinary system stone patients
Authors: Güler Yavuz
Published: February 2024

Aim: Obesity and metabolic syndrome are becoming more prevalent these days. In addition, we know that urinary stone disease is also on the rise. In this study, we wanted to examine if body mass index (BMI) had a negative effect on the stone disease by evaluating 24-hour urinalysis in stone patients and recurrence rates in our region.

Materials and methods: From January 2017 to December 2019, a total of 193 patients were assessed retrospectively in terms of their 24-hour urine analysis results and blood parathyroid hormone (PTH) values. These patients were divided into 3 groups by their BMI <25, 25-30, and ≥30 (group 1, 2, and 3, respectively). Demographic and 24-hour urine analysis data were compared between the groups. Patients with and without recurrent stones were divided into 2 groups and lithogenic factors were analyzed. Possible lithogenic risk factors for recurrent stone formation were examined in a multivariate logistic regression analysis. Pearson and Spearmen correlation analysis was used for correlation.

Results: Groups 1, 2, and 3 had 107, 55, and 31 patients, respectively. There was a statistically significant difference between the groups in their BMI, diabetes mellitus (DM), hypertension (HT), gout, spontaneous stone passage, and extracorporeal shock wave lithotripsy (ESWL) factors. While the mean of BMI was similar for groups 2 and 3, the mean of group 1 was statistically significantly lower. Group 3 exhibited statistically significant higher rates of DM, HT, and gout diseases in comparison to the other groups. ESWL and spontaneous stone removal factors were statistically significantly higher in groups 2 and 3 than in group 1. According to the results of the 24-hour urine analysis, the urinary pH, uric acid, calcium, oxalate, and phosphate values were statistically different in group 1 from other groups. Urinary pH was more acidic and uric acid, calcium, oxalate, and phosphate values were higher in groups 2 and 3. Only BMI was statistically different from the lithogenic factors in the patient groups with and without recurrent stones. Also, in the multifactorial logistic regression analysis, BMI factor was found to be significant in duplicate stone formation. There was a weak but statistically significant correlation between the amount of uric acid and stone volume (r=0.307, p=0.04).

Conclusion: Increased BMI negatively affects the lithogenic factors in urine and facilitates the formation of recurrent stones.

Authors: Zhang Mingming , Jin Huiyuan , Yang Ying
Published: February 2024

In addressing the key issues of the data imbalance within ECG signals and modeling optimization, we employed the TimeGAN network and a local attention mechanism based on the artificial bee colony optimization algorithm to enhance the performance and accuracy of ECG modeling. Initially, the TimeGAN network was introduced to rectify data imbalance and create a balanced dataset. Furthermore, the artificial bee colony algorithm autonomously searched hyperparameter configurations by minimizing Wasserstein distance. Control experiments revealed that data augmentation significantly boosted classification accuracy to 99.51%, effectively addressing challenges with unbalanced datasets. Moreover, to overcome bottlenecks in the existing network, the introduction of the Efficient network was adopted to enhance the performance of modeling optimized with attention mechanisms. Experimental results demonstrated that this integrated approach achieved an impressive overall accuracy of 99.70% and an average positive prediction rate of 99.44%, successfully addressing challenges in ECG signal identification, classification, and diagnosis.
Stability analysis of a SAIR epidemic model on scale-free community networks
Authors: Zhang Xing , Li Zhitao , Gao Lixin
Published: February 2024

The presence of asymptomatic carriers, often unrecognized as infectious disease vectors, complicates epidemic management, particularly when inter-community migrations are involved. We introduced a SAIR (susceptible-asymptomatic-infected-recovered) infectious disease model within a network framework to explore the dynamics of disease transmission amid asymptomatic carriers. This model facilitated an in-depth analysis of outbreak control strategies in scenarios with active community migrations. Key contributions included determining the basic reproduction number, $ R_0 $, and analyzing two equilibrium states. Local asymptotic stability of the disease-free equilibrium is confirmed through characteristic equation analysis, while its global asymptotic stability is investigated using the decomposition theorem. Additionally, the global stability of the endemic equilibrium is established using the Lyapunov functional theory.

Le Japon, un modèle de laïcité pour la France au moment de la loi de 1905 ? Interactions, malentendus et appropriations réciproques
Authors: Date Kiyonobu
Published: February 2024

La laïcité est souvent perçue comme une exception française. Or, ce n’est pas ce qu’en pensaient les pères fondateurs. En effet, le rapport d’Aristide Briand affirme que « la séparation complète des Églises et de l’État » comptait « de nombreux partisans » au Japon. Ce rapporteur du projet de loi de 1905 a écrit ces mots en se référant à un article d’Alexandra Myrial, alias David-Néel. Notre article a pour but d’identifier sur quelle source elle se serait appuyée pour écrire son texte, mais aussi de réfléchir au contraste entre son évocation de la situation politico-religieuse du Japon pour promouvoir la laïcité en France et l’intention de l’auteur japonais qu’elle a consulté, celui-ci étant au contraire en faveur du système concordataire français.

Comparison of Infectious Complications in Patients Receiving High-Dose Cyclophosphamide as GvHD After Transplantation From A 9/10 HLA-Matched Unrelated Donor with Standard GvHD Prophylaxis After Transplant From A Full Matching Donor
Authors: SAYIN Selim
Published: February 2024

Background: The aim of this study was to evaluate whether cyclophosphamide administered after allogeneic stem cell transplantation (ASCT) from 9/10 HLA-Matched Unrelated Donors (MMUD) increases the rates of bloodstream infections (BSI) (fungal, viral (CMV, BK, hepatitis), bacterial), infectious complications (hemorrhagic cystitis(HC)) and infection-related mortality compared to allogeneic stem cell transplantation from matched related donors (MRD).

Metods: This is a retrospective multicenter study. 45 MMUD ASCT patients who received posttransplant cyclophosphamide + methotrexate + calcineurin inhibitor compared with 45 MRD ASCT patients who received methotrexate + calcineurin inhibitor.

Results: Although there was a statistically significant prolongation of neutrophil engraftment time in the PTCy arm, there was no statistically significant difference in bacterial BSI frequencies between the groups (PTCy; 9(20%), control;8 (17.8%), p=0.778). The distribution of CMV infection in the first 100 days was similar (p=0.827) but the distribution of CMV infection rate between the 100th and 365th days, was observed more frequently in the control group (p=0.005). HC rates and their grades were similar in both groups (PTCy; 4 (8.8%), control;6 (13.3%) p=0.502). The rates of VZV infection and invasive aspergillosis were similar in the PTCy and control groups (13.3% in the PTCy, and 17.8% in the control group p=0.561). IRM rate was statistically similar in both groups (13.3% in the PTCy arm and 17.8% in the control arm)

Conclusions: The addition of PTCy to standard GvHD prophylaxis in MMUD ASCT does not lead to an increase in CMV reactivation, bacterial BSI, invasive fungal infection, viral hemorrhagic cystitis or infection-related mortality.
The South African Defence Force versus SWAPO And Its Allies: Operation Askari, 1983-1984
Authors: Oosthuizen G.J.J.
Published: February 2024

Die Suid-Afrikaanse Weermag (SAW) en die Suid-Afrikaanse Polisie (SAP) was betrokke in militêre konflik met die bevrydingsbewegings vir die volle duur van die sogenaamde grensoorlog aan die noordelike grens van SuidwesAfrika (Namibië). Die South West African People’s Organisation (SWAPO, gestig in 1960) het hom beywer vir die bevryding van die gebied via militêre aksies teen die Suid-Afrikaanse magte. Vir hierdie doel is ‘n militêre vleuel, die People’s Liberation Army of Namibia (PLAN), gestig. Internasionale gebeure het daartoe bygedra dat die geveg om Suidwes-Afrika nie slegs tot SWAPO en die Suid-Afrikaanse magte beperk was nie. As gevolg van ‘n coup d’etat en die ekonomiese en morele las wat die kolonies meegebring het, het Portugal inderhaas in 1974 uit Angola en Mosambiek onttrek. SWAPO, met die ondersteuning van die MPLA, het militêre basisse in die suide van Angola gevestig, sodat hulle Suidwes-Afrika meer effektief van daar af kon binnedring. Dit was slegs ‘n kwessie van tyd voordat die Suid-Afrikaanse magte nie slegs met SWAPO te doen gekry het nie, maar ook met die MPLA en die Kubaanse magte. Suid-Afrika het egter nie ‘n houding ingeneem van wag en sien nie, maar wou die inisiatief behou, hoofsaaklik deur middel van sogenaamde transgrensoperasies. Tussen 6 en 27 Januarie 1976 is nie minder nie as 35 Suid-Afrikaanse burgermageenhede opgeroep om deel te neem aan Operasie Savannah, die eerste van vele oorgrensoperasies wat sou volg. Die algemene doel van hierdie operasies was om ‘n effektiewe teenvoeter te wees vir die insypeling van SWAPO in Suidwes-Afrika vanuit die suide van Angola. In hierdie artikel word die botsings tussen SWAPO en sy bondgenote aan die een kant en die SAW aan die ander kant krities bespreek. Die fokus sal wees op die mislukte pogings van die SAW om die SWAPO/MPLA/Kubaanse vestings in Cahama, Mulondo en Cuvelai in suidelike Angola tydens Operasie Askari (1983-1984) te verower.

Alhoewel die eerste demokratiese verkiesing in Suid-Afrika reeds 12 jaar gelede gehou is, is die kriteria gebruik deur die Onafhanklike Verkiesingskommissie (OVK)1 om die April 1994 verkiesing “vry en regverdig” te verklaar nog nooit waarlik deur historici en politieke wetenskaplikes nagevors nie. ‘n Vraag wat reeds ‘n lang tyd by studente van die geskiedenis en politiek bestaan is of die OVK geoorloof was om die verkiesing van April 1994 in Suid-Afrika as “vry en regverdig” te verklaar “ondanks geweld en intimidasie wat gedurende dié tyd voorgekom het”? Het dit oor die nodige kennis en menslike hulpbronne beskik om die verkiesing “vry en regverdig” te verklaar? Het dit die vermoë gehad om daadwerklik die veelvuldige probleme insluitende geweld, intimidasie en verkiesingsbedrog gedurende die verkiesingsperiode die hoof te bied? DL Horowitz, lid van die Demokratiese Party (DP), het nadat hy van die talle probleme ondervind deur die OVK te hore gekom het, verklaar dat die April 1994-verkiesing in werklikheid geen verkiesing was nie, maar eerder ‘n sensus. In dié artikel probeer die navorser Horowitz se stelling én die komplekse proses rondom die 1994-verkiesing ontleed.

Dual-purpose cropping (sowing crops with the intention of both grazing them during vegetative growth and harvesting grain thereafter  for household consumption) is certainly a promising way to address challenges face by small-scale dairy farmers in Benin due to climate  variability and change. This study evaluated the impact of climate variability and change on dual-purpose crops productivity  performances and nutritional values in Benin’s climatic regions. Four dual-purpose crops were studied. They are maize fodder, sorghum  fodder, peanut fodder and cowpea fodder. The grain yield across various climate regions and years were assessed. Also fodders samples  were analysed according to official methods of AOAC. The results showed that dual purposes crops yield were significantly affected  particularly in some years in many regions of Benin by climate parameters variation. The variation of humidity had a negative effect on  cereals dual-purpose crops production in Guinean region while the impacts of temperature and rainfall on dual purpose crops were  higher in Sudanian region. The model for predicting the resistance of dual-purpose crops to climate variability and change revealed that  The Annual Yield of Sorghum Grain was significantly influenced by humidity (P=0.0111), Rainfall (P=0.0374) and Weather station/Region  (P=0.0493), as well as by the interaction between temperature and Grain Yield per Hectare (P=0.0423). The annual quantity of maize  produced varied significantly with temperature (P=0.00154), humidity, Rainfall (P=0. 00792), Weather station/ Region (P=0.00362). The  Annual Yield of Cowpea Grain production varied significantly with Temperature and Humidity (0.0205). Furthermore, temperature,  humidity, year and Grain Yield per Hectare significantly affected the Annual Yield of Peanut Grain Produced. Nutritional values of the four  studies dual-purpose crops were assessed. The energy values were 0.60 and 0.50 UFL/kg of Dry Matter respectively for sorghum-fodder  and maize-fodder, the contents of digestible nitrogenous materials (MAD) were 1 and 0 g/kg of DM respectively for sorghum-fodder and  maize-fodder. If the energy values were quite good for cereals fodder, the nitrogen values were very low. This study highlighted the  nutritional advantage of leguminous fodders over cereal fodders.

Le tilapia du Nil est une espèce aquacole majeure dont la gamétogénèse est fortement modulée par la température. Ainsi, de nombreux  travaux ont été consacrés à l’étude de l’influence des traitements thermiques sur la spermatogénèse chez cette espèce. Le présent article  a pour objectif de faire un état des connaissances de l’influence de la température sur la spermatogénèse chez le tilapia du Nil.  Les connaissances disponibles sur l’organisation testiculaire, l’évolution des cellules germinales et le rôle des cellules somatiques chez le  tilapia de Nil ont d’abord été présentées. Les travaux relatifs aux effets de la température sur la spermatogénèse chez cette espèce ont  ensuite été synthétisés à quatre niveaux à savoir l’influence des basses températures (≤ 20°C), les hautes températures (35°C) chez les  mâles matures, les hautes températures de masculinisation (36°C) et les hautes températures stérilisantes (37°C). Les différents travaux  concordent avec le fait que les basses températures compromettent l’évolution de la spermatogénèse chez le tilapia du Nil tandis que les  hautes températures accélèrent la spermatogénèse chez les mâles matures. Il ressort également que l’influence des traitements  thermiques d’inversions sexuelles ou de stérilisations sur les cellules germinales, serait corrélée avec la variabilité inter ou intra souche  de la thermosensibilité de la différenciation sexuelle.

 

English title: Influence of temperature on Nile tilapia spermatogenesis,  Oreochromis niloticus (Linnaeus, 1758): a synthesis

Temperature highly modulates gametogenesis of a Nile tilapia which is the major aquaculture species. Many studies have therefore been  devoted to studying the influence of thermal treatments on spermatogenesis in this species. This article reviews what is known about the  influence of temperature on spermatogenesis in Nile tilapia. Available knowledge on the testicular organization, germ cells evolution and  the role of somatic cells in Nile tilapia was first presented. Studies on the effect of temperature on spermatogenesis in this species was  then synthesized at four levels, namely the influence of low temperatures (≤ 20°C), high temperatures (35°C) in mature males,  masculinization high temperatures (36°C) and high sterilizing temperatures (37°C). The various studies were consistent with the fact that  low temperatures compromise the evolution of spermatogenesis in Nile tilapia, while high temperatures accelerate spermatogenesis in  mature males. It is also evident that influence of heat treatments for sexual inversion or sterilization would be correlated with inter or  intra-strain variability of thermosensivity in sexual differentiation.
Immediate complete dentures: a case report.
Authors: OGUNRINDE Tunde Joshua
Published: February 2024

Background:  Immediate complete denture is one of the treatment options in patients requiring extraction. It plays a significant role in the immediate restoration of aesthetics and other oral functions. The dentures are fabricated before the extraction of all the remaining teeth and delivered immediately to the patient after the extraction.

Case: This presents a case of a patient with aggressive periodontitis managed with an immediate complete denture. The patient had reservations about conventional complete dentures due to concerns about being seen as edentulous while extraction sockets healed. The patient was satisfied with the simple and economical treatment modality of immediate complete denture.
Assessment of knowledge of the association between periodontitis and systemic conditions among clinical medical and nursing students

Background: Periodontitis has been linked to some systemic conditions. The knowledge of this association by qualified health professionals and those in training is very vital in holistic patient care.

Objective: To assess knowledge of the association between periodontitis and systemic conditions among clinical medical and nursing students

Method: This was a descriptive cross-sectional study conducted among clinical medical and clinical nursing students of the University of Port Harcourt, Rivers State, Nigeria. A total of 200 questionnaires were administered with 156 properly filled. Section A of the questionnaire had questions on the sociodemographic characteristics of the respondents, while section B included questions on the assessment of participants’ awareness and knowledge regarding the possible link between periodontitis and some systemic conditions. Data analysis was done using SPSS version 25.0 with p ≤ 0.05 considered statistically significant.

Results: A total number of 156 clinical medical and nursing students participated in the study, 99 (63.5%) were females, while the remaining 57 (36.5%) were males. The age range of the participants was 19-35 years with a mean age of 23.31 ± 2.50 years.   Of the 156 participants, 85 (54.5 %) were clinical medical students while 71 (45.5%) were clinical nursing students. 74.4% of the medical students and 35.7% of the nursing students knew that there was a possible link between periodontitis and diabetes mellitus (p=0.000). 54.9% of medical students and 30.0% of nursing students agreed that there is a possible link between periodontitis and cardiovascular disease (p=0.001). Using Bloom’s concept, 69 (81.2%) of the medical students and 53 (74.6%) of nursing students demonstrated low knowledge about the link between periodontitis and systemic conditions, 

Conclusion: There was an inadequate level of knowledge of the possible association between periodontitis and some systemic conditions among the participants. Hence, there is a need to include oral health education in the undergraduate curriculum of both medical and nursing students.
