Preventive Maintenance and Replacement Model for Mechanically Repairable Systems with Linearly Increasing Hazard Rate
Authors: Udoh Nse , Uko Iniobong
Published: November 2023

Most machines fail due to lack of appropriate preventive maintenance (PM) and replacement schedule, and this failure leads to higher cost of repair maintenance, distortion of production schedule, elongated downtime period and reduced productivity. These could however be avoided by the utilization of optimal PM and replacement models suited for the specific kind of system. It is on this premise that this work develops an optimal PM and replacement model for mechanically repairable systems with linearly increasing hazard rate which failure distribution of the system is characterized by the Rayleigh distribution. The failure times of a Rolls Royce dredging machine was used as real-time data to obtain the PM and replacement schedule for the machine at respective cost ratios. The results showed that the model provided an effective maintenance schedule for the machine and ensures optimal performance.

Published: November 2023

COVID-19 has emerged as the biggest threat to the world’s population, since December 2019. There have been fatalities, financial losses, and widespread fear as a result of this extraordinary occurrence, especially in Malaysia. Using available COVID-19 data from the Ministry of Health (MOH) Malaysia website, from 25/1/2020 to 17/6/2022, this study generated regression models that describe the trends of COVID-19 cases in Malaysia, taking into account the unpredictable nature of COVID-19 cases. Three techniques are used in Weka software: 60:40 / 70:30 split ratio, 10 and 20-fold cross-validation, Support Vector Regression (SVR), Multi Linear Regression (MLR), and Random Forest (RF). Based on new instances among adults, the study’s findings indicate that RF has the strongest coefficient correlation and the lowest Root Mean Square Error of 22.7611 when it comes to predicting new COVID-19 deaths in Malaysia. Further investigation into prospective characteristics like vaccination status and types, as well as other external factors like locations, could be added to this study in the future.

Authors: Miller Patricia Tamunoibi
Published: November 2023

This research aims to investigate the current state of sexuality education in Nigeria, identify the challenges faced in advocating for comprehensive sexuality education, and propose effective strategies to promote its implementation for improved sexual health outcomes among Nigerian youth. Sexuality education remains a critical yet often neglected aspect of youth development and public health in Nigeria. The country's socio-cultural context, conservative values, and religious beliefs have created barriers to the implementation of comprehensive sexuality education programmes. This paper seeks to address the gap in knowledge by examining the specific challenges that hinder the advancement of comprehensive sexuality education and by proposing evidence-based advocacy strategies to overcome these barriers. The study employs a mixed-methods approach, combining qualitative and quantitative research methods to provide a comprehensive understanding of the subject matter. Qualitative methods such as interviews, focus group discussions, and content analysis of relevant documents are used to explore the challenges and perceptions surrounding sexuality education in Nigeria. Additionally, quantitative surveys are administered to gather data on public attitudes towards sexuality education, perceived benefits, and barriers to implementation. The paper contributes to the ongoing dialogue on sexuality education in Nigeria by providing a nuanced understanding of the challenges and opportunities for advocacy. The proposed strategies will offer evidence-based solutions for promoting comprehensive sexuality education that is sensitive to Nigeria's cultural context. Ultimately, the research aims to inform policymakers, educators, and advocacy organizations about effective ways to advance comprehensive sexuality education for the holistic development and improved sexual health outcomes of Nigerian youth.

Authors: Wilmot Dennis , Owusu Kofi Acheaw , Ayimbila Ezekiel Akotuko
Published: November 2023

Confirmatory factor analysis was conducted on survey data from 149 Senior High School biology teachers in Ghana to validate Magnusson's framework of pedagogical content knowledge (PCK) in science teaching. The questionnaire aligned with Magnusson's conceptualization of PCK, encompassing components like teaching orientations, knowledge of students' understanding, instructional strategies, assessment, and science curriculum within genetics. The results affirmed the integrative model of PCK, indicating strong interactions among its components. While the transformative model also showed relevance, its imposition led to a notable decrease in goodness of fit. This underscores the applicability of Magnusson's integrated PCK model for understanding Ghanaian SHS teachers' PCK in genetics instruction. The findings emphasize the importance of integrated training in knowledge domains like assessment, instruction, curriculum, and understanding to foster effective teaching.

Published: November 2023

Cost-effectiveness analysis (CEA) is a pharmacoeconomic method that compares prices from all sources consumed (cost) with the outcome value of a program or intervention to obtain objective answers to the selection of drugs that are effective in terms of benefits and costs. COVID-19, or Coronavirus Disease 2019, is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCoV-2) and causes acute respiratory distress, including fever, coughing, and shortness of breath. Fondaparinux, aside from heparin and enoxaparin, can be given as an anticoagulant therapeutic option in hospitalized COVID-19 patients, according to the third edition of the COVID-19 care recommendations. This study aimed to find the most cost-effective therapy among heparin, enoxaparin, and fondaparinux in COVID-19 patients at the RSUD’45 Kuningan. It also applied descriptive non-experimental research methods with retrospectively collected data. The intervention that had been studied was the administration of anticoagulant medication, where the effectiveness of the drug was observed in the reduction of D-dimer levels to normal levels. Meanwhile, the costs were observed from the perspective of a healthcare provider, specifically the RSUD’45 Kuningan. The study sample included 107 patients, with 13 receiving heparin, 41 receiving enoxaparin, and 53 receiving fondaparinux. Bivariate analysis using the chi-square test revealed no significant difference between the drug groups in the proportion of patients who improved and did not improve (sig. value = 0.610)...
QUALITY ANALYSIS AND IDENTIFICATION OF FUNCTIONAL GROUPS OF SWEET ORANGE (Citrus sinensis) PEEL ESSENTIAL OIL USING FTIR
Authors: Cantika Citra Dhea , Nurani Laela Hayu , Salamah Nina
Published: November 2023

Organic waste in the form of citrus fruit peels has not been handled seriously, causing environmental pollution, such as the emergence of unpleasant odors.  Therefore, waste management becomes a more valuable product or item.  Citrus peel oil counterfeiting often occurs because there is no Indonesian National Standard (SNI) for citrus peel oil as a quality standard, making it difficult to identify the falsity of finished citrus peel oil products in the market. Research was conducted to test the quality of sweet orange peel oil so that it could be used as a standard to identify the content of sweet orange peel oil using the FTIR method. Oil quality testing included an organoleptic test, specific gravity, refractive index, and acid number. The oil quality test results showed clear yellow oil with a distinctive sweet orange peel aroma, specific gravity of 0.845, refractive index of 9.263, and acid number of 1.1. FTIR analysis revealed spectra that appeared in the region of 1490 with strong intensity (C-H aromatic), 1645 with medium intensity (C=C), and 2860 with medium intensity (C-H aliphatic). FTIR spectra of sweet orange peel oil showed similarity with limonene with a hit quality value of 958, the content of sweet orange peel oil is dominated by limonene compounds.

Effort-Reward Imbalance en de mentale gezondheid van managers in Europa
Authors: Vos Mattias , De Moortel Deborah , Vanroelen Christophe
Published: November 2023

**Objectives**: according to the Neo-Marxist Social Class (NMSC) Theory, social inequalities can be partly explained by positions of authority. Higher positions of authority imply higher rewards conceptualized as ‘loyalty rent’. In contemporary workplaces a reduced need for loyalty and therefore also rewards can be expected. We investigate how the interaction between positions of authority and Effort-Reward Imbalance (ERI) is related to mental health.**Methods**: from the 6th wave of the European Working Conditions Survey, we selected workers aged 15 to 64 from 28 European Member States. ERI was measured with 18 proxies for the ERI Questionnaire. For mental health, the WHO-5 well-being index was used. Relationships were analyzed using linear regression models. **Results**: we found a relationship between ERI and mental health for European employees. We did not find worse mental health for middle managers, but we did for higher managers. The vulnerability for ERI is higher in positions of authority with the expectation of loyalty rent attached to leadership roles. The mental health of female middle managers appears more vulnerable to ERI than men's.**Conclusions**: our findings show that mental health risks of middle and higher managers become apparent especially in situations where rewards do not match the status expectations of the position.

Le corps confiné aujourd’hui. Conséquences psychomotrices de restrictions qui ne portaient pas que sur l’expression des émotions par le visage
Authors: Békier Séverine , Saint-Cast Alexandrine
Published: November 2023

À tous les âges du développement psychomoteur, les émotions sont essentielles. Elles émergent et circulent par le tonus musculaire et ses variations. C’est par cette voie qu’elles influencent l’équilibre psychomoteur. Les interactions émotionnelles, perceptives et motrices de l’enfant avec son environnement façonnent ses compétences psychomotrices. Les observations des actions des enfants qui consultent actuellement en psychomotricité, et qui ont traversé le confinement, confirment que c’est par l’activité et l’expérience de son corps que l’enfant développe les compétences, pour se connaître, connaître son monde, y agir et s’y adapter.

Les conséquences des combats de la Première Guerre mondiale en Prusse-Orientale (1914-1924)
Authors: Ferrebeuf Florian
Published: November 2023

Entre août 1914 et février 1915, les armées allemandes et russes s’affrontent violemment en Prusse-Orientale. Seule province allemande directement touchée par les combats de la Première Guerre mondiale, elle en subit de lourdes conséquences. Les destructions sont nombreuses et parfois spectaculaires. Au niveau humain, les exactions contre la population sont réelles. Beaucoup d’Austro-prussiens fuient les zones de combat, et plusieurs milliers sont enlevés par les Russes. Vient ensuite le temps des reconstructions. Durant près d’une dizaine d’années, les autorités vont planifier et mettre en œuvre la réparation des dommages de guerre. Tout l’appareil d’État est mobilisé, mais cet effort prendra fin vers 1924, devant les problèmes économiques de la République de Weimar.
Normandie-Niemen : l’amalgame des aviateurs de la france libre et de l’armée d’armistice au cœur de l’URSS
Authors: Baldini Charles
Published: November 2023

Durant l’hiver 1943-1944, Normandie-Niémen, pour devenir un régiment de chasse de la nouvelle armée de l’air réunifiée, doit recevoir de nombreux renforts de l’ancienne armée d’armistice. L’escadrille emblématique de la France libre, combattant aux côtés des Soviétiques depuis le début de l’année, doit réaliser un amalgame de grande ampleur. À partir des témoignages des vétérans, notamment des archives orales conservées par le Service Historique de la Défense (SHD), cet article vise à étudier la manière dont l’amalgame a été réalisé malgré les fortes tensions entre les pilotes qui, pendant deux ans, se sont opposés parfois les armes à la main.
« Fusillés sans jugement ». La répression extrajudiciaire du maquis de Rohantic, un épisode précurseur dans le Finistère (15 et 16 juin 1944)
Authors: Landrein Pierrig
Published: November 2023

Au cours des 15 et 16 juin 1944, dans la commune d’Elliant, les troupes allemandes abattent sommairement sept maquisards présents au maquis de Rohantic et incendient quatre habitations. Alors que des évènements similaires se produisent concurremment dans tout le pays, dans quelle mesure la répression qui s’abat sur cette localité du sud du Finistère revêt-elle un caractère singulier ? Bien qu’étant l’un des premiers cas de répression extrajudiciaire, la littérature n’a abordé cet évènement qu’au travers de son aspect héroïco-martyrologique. C’est l’apport d’archives inédites, telles que les auditions des soldats allemands présents durant les opérations, qui autorise une lecture nouvelle de ces deux journées. Ces documents révèlent alors l’existence de tensions entre les unités allemandes.

O nastanku hidrografske mreže in o nekaterih kraških pojavih na Idrijskem
Authors: Mlakar Ivan
Published: November 2023

Rekonstruirali smo geološke razmere na nivoju najmlajšega - pliocenskega ravnika v današnji višini 1000 metrov. Pokazali smo, da so takratne litološke in tektonske okoliščine imele pri nastajanju hidrografske mreže odločilno vlogo, kar velja tudi za pretočitve Kanomljice, Nikove, Idrijce in Belce. Območje južno in NW od Idrije izpolnjuje vse pogoje, da postane klasično ozemlje za preučevanje začetnega stadija zakrasevanja, zato smo namenili tej problematiki posebno pozornost. Pri nastajanju kraških objektov je igral pomembno vlogo zlasti sistem prečnoalpskih prelomov in razpok. S teorijo brezen smo med drugim obrazložili nastanek Divjega jezera in pokazali, da so bile vsaj nekatere vrtače zasnovane že v obdobju, ko so kredne apnence še prekrivale slabše vodoprepustne kamenine. Antiklinalne strukture so se izkazale kot najboljši indikator za prisotnost podzemnih kraških prostorov. Na koncu prispevka smo tabelarno predstavili še rezultate 60 kompletnih silikatnih analiz skoraj vseh kamenin na Idrijskem. Geological structure on the Pliocene paleosurface level in the nowadays 1000 m altitude were reconstructed. The lithological and tectonical circumstances in that time played a decisive role in hydrographic net origin and also on Kanomljica, Nikova, Idrijca and Belca rivers piracy. Landscape south and NW from Idrija fulfil all conditions to become classical region for initial karstification stadium examination, for that reason to this problems great attention have been paid. Particularly system of cross alpine faults and fissures played significant role on karst phenomena origin. With potholes theory the origin of Wild Lake have been explained and pointed out, that some dolinas at least have been projected already in period when Cretaceous limestones were covered by worse waterpermeable rocks. Anticline structures proved as the best indicator for karst rooms presence. On article end the results of 60 complete silicate analyses of nearly all Idrija's rocks in table shape are presented.
The Effect of Darab Salt Dome on the Quality of Adjacent Karstic and Alluvium Aquifers (South of Iran)
Authors: Sharafi A. , Raeisi E. , Farhoodi G.
Published: November 2023

Zakrasele kraške formacije vsebujejo najpomembnejše vodne vire osrednjih delov jugovzhodnega Irana. Če kraška voda ni onesnažena zaradi slanih dom, je v tem delu Irana njena električna prevodnost pod 500 µS cm-1. Področje raziskav je južno krilo antiklinale Shahneshin-Milk, 200 km vzhodno od Shiraza, ki sodi v narivno cono Zagrosa. Kraška formacija Tarbur (zgornji Campanij-Maastrichtij) izdanja v južnem krilu antiklinale Shahneshin-Milk, pod katero je neprepustna radiolaritna formacija. Solna doma Darab izdanja znotraj zakrasele formacije Tarbur. Iz formacije Tarbur priteka več izvirov. Kvaliteta vode vseh izvirov je v mejah neonesnažene kraške vode razen treh, ki so v bližini solne dome. Električna prevodnost teh treh izvirov je med 1200 in 2000 µS cm-1. Del aluvija okoli solne dome je slano močvirje, ki ga obrobljata dva kanala. Električna prevodnost močvirske vode pod nivojem talne vode je okoli 1400 µS cm-1, v večjih globinah pa se zmanjša na 400 µS cm-1. Odtok s solne dome Darab in prenikanje vode nizke kakovosti iz kanala sta najbrž glavna vzroka za nastanek slanega močvirja. Pomemben delež onesnažene kraške vode iz Tarburja ne teče proti močvirju, saj, prvič, večina kraške vode iz Tarburja priteka na dan skozi izvire, in drugič, na globlje plasti aluvijalnega vodonosnika onesnažena voda ne vpliva.Karstified carbonate formations are among the most important water resources in the south-central regions of Iran. If the karst water is not contaminated by salt domes, the electrical conductivity of water in the karst aquifer is less than 500 µS cm-1 in the south-center of Iran. The study area is located in the southern flank of Shahneshin-Milk anticline, 200 km east of Shiraz. This region is situated in the Zagros Thrust Zone. The Tarbur karstic formation (Late Campanian-Maastrichtian) is outcropped on the southern flank of the Shahneshin-Milk anticline which is underlain by the impermeable Radiolarite formation. The Darab salt dome outcrops inside the karstified Tarbur Formation. Several springs emerge from the Tarbur Formation. The quality of all springs is in the range of unpolluted karst water except for three springs which are located near the Darab salt dome. The electrical conductivity of these springs range from 1200 to 2000 µS cm-1. Part of the alluvium near the Darab salt dome is salt-marsh which is bounded by two channels. The electrical conductivity in the salt-marsh below the water table is about 1400 µS cm-1, and it reduces to 400 µS cm-1 at the lower depths. Run-off from the Darab salt dome and seepage from the channel with low quality water are probably the main reasons of salt-marsh development. A considerable amount of polluted Tarbur karst water does not flow towards the marshland because, firstly, most of the Tarbur karst water discharges from the springs, and secondly, the alluvium aquifer is not affected by polluted water at lower depths.

V vzorcih iz treh različnih jam smo proučevali mikroorganizme, ki jih lahko gojimo v laboratorijskih razmerah. V jami Pečina v Borštu smo prisotnost mikroorganizmov proučevali v preperelem apnencu, jamskem srebru in v jamski ponvici, kjer se na površini velikokrat pojavljajo kalcitne ploščice; v Martinski jami v preperelem apnencu, v Snežni jami na Raduhi pa kalcitno jamsko mleko. Podatki o številu mikroorganizmov so bili v nekaterih primerih dopolnjeni πe z identifikacijo širše skupine ali rodu. Rezultati kažejo, da so poleg še nekaterih drugih bakterijskih in glivnih taksonov fluorescentne pseudomonade prevladujoči mikroorganizmi.Various microenvironments in three different caves were screened for the presence of indigenous culturable microorganisms: extremely weathered limestone in Pečina v Borštu and Martinska jama, cave silver and calcite rafts on the surface of subterranean ponds in Pečina v Borštu and calcite moonmilk speleotheme in Snežna jama of Raduha mountain. The counts of viable cells collected are supplemented with laboratory data necessary to establish genus or wider taxonomic group level identity of isolates. Besides other bacterial and fungal groups flourescent pseudomonads are prevailing among isolates.

Published: November 2023

This paper addresses the issue of efficient resource allocation in a Mobile Edge Computing (MEC) system, taking into account the trade-off between energy consumption and operation latency. The increasing deployment of connected devices and data-intensive services in the Internet of Things (IoT) poses significant challenges in terms of managing computational resources. In this study, we propose a MEC system model that considers energy constraints and the need to minimize latency to ensure optimal performance. We formulate the resource allocation problem in terms of a trade-off between energy consumption and latency, and explore solutions based on heuristic task offloading techniques. Our experiments demonstrate that our approach achieves improved latency performance while reducing energy consumption. We also evaluate the impact of various parameters, such as workload and resource availability, on the energy-latency trade-off.

We live in a modern environment where learning does not have any barriers. Our work aims to become the main gateway for people of any interest to take advantage of the full opportunities of e-learning. We also built a dataset of e-learning courses from various sources and developed a platform that can understand search queries. We introduce a unified massive open online courses (MOOCs) searching platform using semantic methodology called MOOCMaven. Our platform can be accessed both via web and mobile. This paper demonstrates the platform’s efficiency in generating a list of courses relevant to search queries. Additionally, MOOCMaven offers an application programming interface (API) collection to ensure access to the data. Our approach could find the gaps in e-learning course discovery and highlight the solution to the public. This paper provides a detailed description of the algorithms, methodologies, and technologies utilized to augment the usefulness and efficacy of the platform.

Published: November 2023

This study aims to explore the intricate relationship between social media use and the overall well-being (WB) of young people. Previous research has presented conflicting findings, indicating both positive and negative effects of online platforms. Issues such as excessive use, reduced face-to-face interactions, social isolation, heightened stress levels, and disrupted sleep patterns have been identified as potential concerns. However, studies have also highlighted that moderate and mindful use of social media can enhance WB by facilitating social connections and support. It is crucial to consider the vulnerabilities of young individuals when examining this complex topic and provide them with age-appropriate guidance. This research project aims to address gaps in the existing literature and inform strategies for promoting positive online experiences and safeguarding the WB of young people by investigating the association between social media use and affective WB. The review process involved systematically searching for relevant research and evaluating its quality and relevance. The analysis encompassed 111 articles and reviews published between 2013 and 2023. The dataset comprised articles with an average age of 2.76 years and an average of 40.45 citations per article, sourced from 78 journals and other publications. Several variables were examined, including authors, publishers, affiliations, countries, and keywords used in the research articles. The discourse surrounding the benefits and drawbacks of social media use was found to be ongoing. Concerns were raised regarding the potential negative consequences of excessive use, including diminished face-to-face interactions, social isolation, increased stress levels, and sleep disturbances. However, it was also observed that moderate and mindful social media use could positively impact WB by promoting social support and connection. Given the complex nature of the relationship between social media use and WB, it is important to acknowledge the vulnerabilities of young people and provide appropriate assistance and guidance tailored to their age group.
What My Friends Are Up To? The Relationship between Social Media Usage and Fear of Missing Out among Undergraduates
Authors: Khatiyayini a/p RYoganathan  , Mohd Rustam Mohd Rameli
Published: November 2023

The social media platform is extremely popular among undergraduate students. Along with the increase in social media usage, phenomena such as the fear of missing out are also becoming more prevalent among this group. It is hypothesized that excessive usage of social media contributes to the psychological decline of undergraduate students. This study aimed to examine the relationship between social media usage and the fear of missing out among undergraduate students. In addition, this study also examined the level of social media usage and the fear of missing out. The study adopted a quantitative approach, specifically a correlational research design. Data were collected from 306 undergraduates at Universiti Teknologi Malaysia using the social networking time use scale and fear of missing out (FOMO) scale instruments to measure social media usage and fear of missing out, respectively. Descriptive analysis revealed that undergraduates have a moderate level of social media usage and a moderate level of fear of missing out. Meanwhile, the inferential analysis revealed a significant positive relationship between the usage of social media and the level of fear of missing out among undergraduates. In conclusion, the study results indicate that social media usage does influence the fear of missing out among undergraduates, although the coefficient was weak.
Possible Impact of the COVID-19 Pandemic on Language and Speech Development and Autistic Behavior in Children
Authors: Halder Susmita , Mahato K. Akash
Published: November 2023

The COVID pandemic had a disabling effect on people of all ages and sexes. The enforced lockdown to curb infection rates is hypothesized to have affected toddlers and young children in the developmental phase. The authors report this observation of a significant increase in the consultation numbers of children with speech and language issues and autistic-like behavior postpandemic from Kolkata, West Bengal, and India. There were striking similarities in the profile of these child cases, adding to the doubt whether the COVID pandemic and subsequent lockdown facilitated in the development of language and speech deficits as well as autistic-like features in developing children. It would be of important to know if the effects are temporary in nature or improve with time. Appropriate intervention strategies are suggested.

Published: November 2023

Mephentermine, a stimulant drug, is used as vasoconstrictor to maintain blood pressure in hypotensive states and shock, but due to its stimulant effects on the central nervous system, it has also been used for performance enhancement by athletes. Here, we discuss three cases where the patients had used mephentermine to enhance their work performance. Case 1: A male in his 30’s, presented with palpitation, headache, and hypertension after 1 year of use of mephentermine which he had started using with the purpose of increasing his work performance. Case 2: A 22-year-old male presented with depressive symptoms following a 3-year history of use of mephentermine after being suggested by peers to enhance performance at gym. Case 3: A 22-year-old male with 2-year history of mephentermine, presented with withdrawal symptoms, after being introduced to mephentermine by his peers to improve physical performance and difficulty stopping its use on his own. It was found that the purpose of mephentermine abuse in all three discussed cases was to enhance performance, either at sports or workplace, which gradually lead to physical or mental complications or withdrawal symptoms. It thus seems imperative to create awareness about the harmful and addictive effects of mephentermine to masses, and simultaneously limiting its easy availability.
Exacerbation of Pica as a Precursor of Psychosis

Published: November 2023

Pica is a sustained, compulsive eating behavior of nonedible substances. Pica has been described as sequelae of psychosis due to its state of disorganization; however, temporal and causal relationship between the two has not been reported in the context of exacerbation of pica before psychosis. Various causes of pica have been identified including malnutrition, iron-deficiency anemia, zinc deficiency, intellectual disability, and obsessive and impulse control disorders. Here, we describe a case of worsening pica which preceded exacerbation of psychosis in an 18-year-old female which was managed with antipsychotics along with complete remission of psychosis and improvement in the severity of pica. The present case highlights the association between psychosis and pica. There has been a rising voice in academia to reclassify pica alongside obsessive–compulsive disorder (OCD) with no absolute consensus. In conclusion, our findings suggest that the exacerbation of pica preceded psychosis and can be construed as an indicator for an upcoming psychotic episode or as a prodromal aspect of psychosis and may be useful for early identification and initiation of treatment in cases of relapsing psychosis.
