Authors: Aniekwu Chijioke Christian , Madubuko Emmanuel Sobechukwu
Published: September 2024

This study examined and identified the level of bacteria present in the hostel to evaluate the potential health hazards for the residents and establish guidelines for controlling indoor air quality. Six (6) rooms were sampled out of 25 rooms at the keystone hostel, each with a height of 10 feet, and an average dimension of 9 feet by 10 feet. The study was done in July and November, 2023. Passive air sampling of settle plate method was employed. The isolates were identified using standard cultural and biochemical identification method. The outcome revealed that the concentration of bacteria isolates rose as media exposure time increased. In July, the maximum bacteria concentration was observed in room 37 at 20min (21.5 x 102CFU/m3) and the minimum in room 49 at 20 min (0.02 x 102 CFU/m3. The concentration of bacteria in room 48 at 20 min was (0.1 x 102 CFU/m3), room 47 at 20 min (11.0 x 102 CFU/m3), room 38 at 20 min (16.5 x 102 CFU/m3), room 39 at 20 min (10.5 x 102 CFU/m3), While for the month of November, the highest bacteria concentration was seen in room 37 at 20min (26.5 x 102 CFU/m3) and the least at room 49 at 20 min (0.09 x 102 CFU/m3). The concentration of bacteria at other room 48 at 20 min (0.3 x 102 CFU/m3), room 47 at 20 min (13.5 x 102 CFU/m3), room 38 at 20 min (19.2 x 102 CFU/m3), room 39 at 20 min (15.1 x 102 CFU/m3). A total of seven (7) distinct bacteria species: Escherichia coli (60%), Staphylococcus aureus (100%), Streptococcus pyogenes (50%), Bacillus cerus (30%), Seratia marcescens (30%), Klebsiella spp (50%) and Proteus spp (50%) were isolated and identified in four rooms ( 37, 38, 39, and 47), with six occupants each, while room 48 and 49 had two occupants respectively; hence bacterial load were relatively non-significant. However, Staphylococcus aureus, Streptococcus pyogenes and Bacillus cerus were identified as the most pathogenic isolates seen in the rooms under study. The study highlights the potential impact of occupancy levels on microbial presence within indoor spaces. The results shows that students in rooms 37, 38, 39 and 47 have a high risk of health and disease implications due to poor ventilation and overcrowding, unlike the students in rooms 48 and 49 with low risk of infectious diseases. Therefore, the study recommends a periodic indoor air quality assessment in the students’ hostel, implementation of good health hygiene practices, maintaining environmental sanitation and managing the environmental factors that supports the multiplication of the bacteria especially in the dry season are crucial to preventing the spread of diseases in the hostel.

Abstract. The interaction of anthropogenic and biogenic emissions around large urban agglomerations remains an important question for atmospheric research and the key question of the ACROSS (Atmospheric Chemistry of the Suburban Forest) project. ACROSS is based on an intensive field campaign in the Paris area, including ground–based measurements in the urban inner center to suburban and forest sites, and on–board aircraft, during the exceptionally hot and dry summer 2022. 3D–modelling represents an important tool in ACROSS to disentangle processes such as emissions, transport and physico–chemical transformations. Here we use the available measurements from the ACROSS campaign in addition to observations from air quality and meteorological networks to evaluate the coupled WRF–CHIMERE model simulation. We find that the WRF model is able to reproduce the meteorological variability during the campaign, in particular two heat waves at the beginning and at the end. The model reproduces the daily ozone maxima well, but overestimates PM2.5 by a factor of 1.5–2, partly due to an overestimation of secondary aerosol, both organic and inorganic. This overestimation was unexpected, and could be related to the specific hot summer conditions. For organic aerosol in the Ile–de–France area, the biases are reduced to about ±20 %. The model allows to explain how the interplay of different processes affects the fine aerosol variability and chemical composition over the campaign sites during two heatwave days: biogenic secondary organic aerosol formation in different forests around Paris, advection of wildfire aerosols, and long-range transport of Saharan dust.

Published: September 2024

The study was carried out to explore the nature of collaboration between the schools of students with neurological and developmental disabilities(SWNDDs)and the community institutions including family, health, general education, and social welfare. The study is carried out through a quantitative survey. The population of the study was teachers, and the parents of students with neurological and developmental disabilities studying in different schools in Punjab. A total number of  100 teachers (both male and female) and 31 parents(Mothers & fathers ) were selected through a simple random sampling technique. Two structured questionnaires, one for teachers and one for parents, were used to collect the data. Each questionnaire consisted of two sections; demographic information and close-ended statements. The validity of the questionnaires was estimated from experts in special education. The reliability of the questionnaires was .83  and .80(Cronbach’s Alpha). The data analysis shows that schools had a low level of collaboration with health and social welfare departments but a moderate level of collaboration with regular education and families of students with NDDs.The need for strong and effective school-community collaboration for the welfare and uplift of students with neurological and developmental disabilities and their parents is recommended.

Published: September 2024

Surface finishing applications are still cumbersome manual tasks, therefore, robotization of the process is of great interest as it allows for automation and increased versatility. However, finishing processes are difficult to automate, mainly because of the variation in material removal. In particular, the

variables involved undergo changes that modify the material removal rate. This paper proposes a methodology for modeling material removal automatically based on experimental data. The procedure consists of monitoring the material removed from the parts under study that are in an automated precision measuring system during the finishing process. Based on the experimental models, a control algorithm for continuous material removal is presented. It guarantees a homogeneous surface finish by varying the robot feed rate. Finally, the results of several experimental material removal models under different process conditions and the validation of the proposed control algorithm are presented. The results show that the proposed method achieves a substantial improvement in the homogeneity of the finish.

Neonatal sepsis is a bacterial bloodstream infection predominant to excessive clinical manifestations frequently associated with loss of existence or irreversible long-term deficits. Antibiotics are the drug of choice to address sepsis, no matter age. In neonates, the lack of dependable requirements for a unique prognosis and the supposition that an early antibiotic administration ought to restrict sepsis improvement in youngsters at chance have brought about an applicable antibiotic overuse for each prevention and therapy. the provision of biomarkers of neonatal sepsis that have to alert the physician to an early analysis of neonatal sepsis may additionally want to decorate the quick and long-term outcomes of real sepsis instances and restrict the indiscriminate and deleterious use of preventive antibiotics. The fundamental aim of this assessment is to summarize the crucial outcomes in this regard and to detail the accuracy of currently used biomarkers for the early prognosis of neonatal sepsis. Literature assessment showed that, irrespective of excessive studies, the diagnosis of neonatal sepsis and the behaviour of antibiotic remedy cannot be at current determined on the basis of a single biomarker. Given the significance of the hassle and the want to decrease the abuse of antibiotics, in addition studies are urgently required. but, as a substitute of looking for new biomarkers, it looks less complicated and greater productive to test combinations of or extra of the existing on hand biomarkers. furthermore, research based mostly on omics applied sciences have to be strongly boosted. but, while geared up for new statistics, the use of the clinical ratings prepared through some medical institutions must be counselled. Based totally on maternal risk factors and infant clinical signs, sepsis threat may be calculated, and a big reduction in antibiotic intake may be obtained.

Effective Information Management Model in Implementing PT Polytama Propindo's CSR Program
Authors: Kurniawan Dwinanto , Lestari Puji , Widowati Dewi , Mulyasantosa Nandang
Published: September 2024

One of the implications of mandatory CSR implementation in Indonesia is informing the community (disclose) about CSR implementation and company stakeholders. The problem analyzed in this research is the negative perception of the surrounding community towards the company, which in turn leads to problems in managing and disclosing information. The research problem was analyzed using General System Theory (GST) and Organizational Information Theory (Karl Weick). GST leads to an understanding that companies and society, including other stakeholders, are one unit (holism). Organizational Information Theory (Karl Weick) is used to analyze how companies overcome ambiguity in the input they receive from the external environment. This research uses a postpositivism paradigm and a qualitative approach. The method used is a case study with a single case multilevel analysis model. The research results show that PT Polytama Propindo has implemented CSR as proven by successfully obtaining PROPER Green Rating (2018, 2019) and Gold Rating (2020, 2021, 2022). However, other findings in this research seem to negate PT Polytama's achievements in implementing CSR, because the community around the company area (Limbangan Village) still has a negative perception of the company. The finding of input (negative perception) from PT Polytama's external environment led to other research findings, namely regarding the importance of building an empowerment program as an "alternative way" for two-way communication with the community in Limbangan Village. This finding is also the output of PT Polytama's efforts to unravel the ambiguity behind the negative perceptions of the Limbangan Village community.Keywords: CSR, PROPER, Perception, Information Processing, Disclosure, PT Polytama Propindo

Published: September 2024

The development of the field of communication has progressed rapidly. One example is a message exchange application like Whatsapp. The advancement of technology and innovation in the field of communication has allowed us to connect with people around the world in an easier and faster way. However, with advances in communication technology, new challenges arise related to information security and privacy of messages that have been sent. One solution to overcome this problem is to apply Cryptographic Techniques. In cryptography, data sent over the network will be disguised in such a way with encryption techniques so that even if the data can be read, it cannot be understood by unauthorized parties. The data to be sent without being encoded is known as plaintext, and after being disguised in an encoding way, this plaintext will turn into ciphertext. The method chosen for this journal is the Diffie-Hellman Key Exchange. In this journal, an analysis will be carried out regarding the end-to-end process of securing encrypted messages using the Python programming language.

L’agriculture extensive et l’étalement urbain soulèvent aujourd’hui des questions sur l’évolution des modes d’occupation des terres et leurs effets sur le milieu. L’objectif de la présente étude est d’évaluer les changements dans la dynamique de l’occupation des terres et d’examiner les modifications futures attendues dans le bassin versant du Massili à Gonsé. L’étude s’appuie sur le traitement des images Landsat (1991 ; 2007) et 2019 (référence), les images SRTM 30 m, les types de sols et les données de population. Le logiciel Terrset (LCM) a été utilisé pour simuler les changements dans l’occupation des terres (2050). L’analyse des résultats de la simulation montre que sous le scénario « LULC-A », en 2050, les savanes, les champs, les eaux de surface, les formations ripicoles et les champs diminueront de surface respectivement de 57,58 %, 23,57 % ; 21,63 % ; 9 % et 5,70 % alors que l’habitat augmentera de 99 % par rapport à la base (2019). Sous le scénario « LULC-B », en 2050, la modélisation indique que les sols nus, les champs et les eaux de surface diminueront respectivement de 83,76 % ; de 37,03 % ; de 22,90 % alors que les savanes, l’habitat et les formations ripicoles augmenteront respectivement de 166,10 %, de 75,05 % et de 71,63 % par rapport à la référence. Les résultats de cette étude apparaissent donc comme un outil d’aide à la décision dans l’aménagement du territoire.

Women farmers tend to have busy daily activity profile and their effectiveness with the use of time resources is in doubt. This study assessed the daily time-use effectiveness and constraints to time use among women farmers in Edo State, Nigeria. Multi-stage procedure; comprising purposive and simple random sampling techniques was used to select 120 women farmers from the three agricultural zones in Edo State, Nigeria. Data were collected using structured questionnaires administered through interview schedules and described with frequency, percentages and mean count while Pearson’s Product Moment Correlation was used to analyse data. Findings show that the majority of women farmers were married (90.8%), more had primary education (34.1%), and about 55.8% earned < N100,000 per annum. Wide gaps existed between the time expected to accomplish tasks and the actual time used (±). Respondents perceived higher effective time-use for more reproductive than productive activities ( ≥ 2.50). Age (r = 0.309; p = 0.000), income (r = 0.267; p = 0.002), household size (r = –0.351;p=0.000) and social association membership (r = –0.103; p = 0.043) were the identified correlates of effectiveness in time use. Constraints to time-use effectiveness included inadequate capital ( = 3.50), dearth of labour-saving technologies ( = 3.34) and gender stereotyping ( = 3.32). Development, dissemination and adoption of affordable time and labour-saving technologies could enhance the time-use effectiveness of women farmers.

Authors: Mattei Eugenia
Published: September 2024

El objetivo de este artículo es abordar la relación entre Nicolás Maquiavelo y el populismo en dos niveles simultáneos: primero, mapeando las investigaciones de Sandro Landi y José Pedro Zúquete sobre la relación entre Maquiavelo y el encantamiento; en segundo lugar, utilizando estos trabajos como marco teórico, proponemos una interpretación de la figura de los encantadores y su conexión con las emociones desde una perspectiva relacional y situada para considerar la relación entre el liderazgo maquiavélico y el pueblo. La organización del artículo se divide en cuatro partes: en la primera se realiza una sistematización de las lecturas sobre Maquiavelo en torno al liderazgo y el republicanismo, con un enfoque principal en trabajos realizados en la región latinoamericana; en la segunda parte se abordan las últimas lecturas propuestas por Landi y Zúquete con el objetivo de desarrollar nuestra hipótesis; en la tercera parte, se sistematiza la perspectiva relacional del encantamiento y la perspectiva situada de las emociones a través de liderazgos maquiavélicos seleccionados; Finalmente se presentan las conclusiones derivadas del trabajo realizado.

A pandemia por Covid-19 representa um dos maiores desafios sanitários em escala mundial deste século. O coronavírus denominado SARS-CoV-2 tem seu processo de transmissão de pessoa para pessoa, que se dá por meio da autoinoculação do vírus em membranas mucosas, sendo o isolamento social sua principal estratégia de prevenção. O ministério da saúde, em 19 de março de 2020 se pronunciou autorizando substituição das aulas presenciais por aulas que utilizem instrumentos tecnológicos de comunicação. Trata-se de uma pesquisa de revisão integrativa que objetivou em identificar os principiais desafios no processo de ensino-aprendizagem no ensino superior advindas da pandemia da COVID-19 e consequentemente, descrever as estratégias metodológicas frente processo de ensino-aprendizagem na pandemia da COVID -19. Assim a revisão foi realizada através da Biblioteca Virtual de Saúde (BVS), nas seguintes bases de dados: LILACS, BDENF e Google Acadêmico, no período de outubro de 2020, com as palavras-chave: COVID – 19; Educação Superior; Pandemia. Foram localizados 52 artigos, realizado leitura flutuante, selecionado 22 e apenas 14 artigos atendiam a proposto a relacionado à temática do estudo. Os artigos foram analisados segundo os passos da análise temática de Bandin e evidenciaram duas categorias: Desafios no processo de ensino-aprendizagem no ensino superior advindas da pandemia da COVID-19 e Estratégias metodológicas frente processo de ensino-aprendizagem na pandemia da COVID -19. Por fim, o estudo evidenciou, através da revisão de literatura, a grande dificuldade, por parte dos docentes, em (re)significar, de forma emergencial, o processo de ensino-aprendizagem nos cursos de graduação.
Intestinal Protozoa and Schistosoma Mansoni (Sambon 1907) Infections Among Some Pupils in Akko Local Government Area of Gombe State, Nigeria
Authors: Twan M. S.
Published: September 2024

The prevalence of intestinal protozoa and Schistosoma mansoni infections among primary school pupils in Akko Local Government Area of Gombe State, Nigeria was investigated. Stool samples were collected from 450 pupils aged 5–13 years in the three (3) districts of Akko Local Government Area. A structured questionnaire was used to collect relevant demographic and risk factor data associated with intestinal protozoa and S. mansoni infections. The stool samples were processed using the formol-ether concentration technique and microscopically examined for protozoan cysts and S. mansoni eggs; 12.4 % of the stool samples were positive for cysts and eggs. The prevalence of intestinal protozoa were: Entamoeba histolytica (4.9 %), Entamoeba coli (3.8 %) and Balantidium coli (2 %); Schistosoma mansoni eggs had a prevalence of 1.6 %. The prevalence of infection with protozoa and S. mansoni infections in individual schools was not uniform despite the similarity in the local topography and weather conditions. Source of drinking water and type of toilet used significantly associated with infection by intestinal protozoa and S. mansoni (Odd’s Ratio value for Pit-latrine was 18.959). The prevalence of intestinal protozoa and Schistosoma mansoni infections among the primary school pupils was associated with poor personal hygiene habits at home and in school, and improper disposal of human and animal waste as implied by the responses to the questionnaire. It is therefore recommended that a concerted health education effort is necessary in order to curb the infections within the schools and the communities.

O processo de ensino aprendizagem ocorre diante das complexidades, próprias da natureza humana e outras emergidas dos diversos contextos sociais que se revelam a partir de fatores socioeconômicos, culturais e políticos. O presente estudo tem como objetivo refletir acerca dos jogos matemáticos como recursos potencializadores da aprendizagem de alunos com TEA. Tendo como questão problema: como os jogos matemáticos enquanto recursos pedagógicos potencializam a aprendizagem de alunos com TEA? O percurso metodológico se fundamenta numa abordagem qualitativa, do tipo de pesquisa bibliográfica e de campo. Os recursos pedagógicos elaborados envolveram jogos com materiais concretos, os quais possibilitaram a interação do aluno com os conceitos matemáticos abordados tanto na sala regular quanto no AEE, oportunizando assim experiências diversificadas em relação ao ensino e aprendizagem matemática. Sendo assim, a matemática assume um papel essencial, visto que oportuniza ao discente a capacidade de raciocinar, contar, refletir, pensar, imaginar, criar, assim como a concentração e atenção estimulando a autoestima pois passa a confiar em si mesmo, se relacionando melhor com a sociedade na qual está inserido, já que o ensino de conceitos matemáticos procura buscar o desenvolvimento cognitivo lógico-matemático oportunizando crescimento e amadurecimento mental e intelectual. A experiência e reflexões aqui expostas não findam o debate sobre os jogos matemáticos enquanto recursos potencializadores de aprendizagem em alunos com TEA, longe disso, acreditamos que estudos precisam ser contínuos e permanentes, tanto em formação inicial quanto formação continuada de profissionais que atuam na educação.
