Employee’s Behavioral Opportunism and Alienation: Exploring the Factors
Authors: Pletnev Dmitri , Kozlova Elena
Published: January 2022

The article aims to identify factors influencing the behavioural opportunism and alienation of Russian employees. The study is based on a survey of 298 Russian employees, conducted in October 2020. Normalized indicators were used to assess the alienation degree, opportunism willingness and opportunism level, based on processing the respondents’ answers; the Z-test was used for statistical analysis of these indicators, and to examine the influence of 14 social and organizational factors on alienation and opportunism. The study showed that employees’ alienation degree is influenced by marital status, having children, motivation type, organization size, work in a managerial position, position and salary improvement, and Adizes’ management styles. Their opportunism willingness is influenced by gender, age, management style, organization-side work experience, and position improvement. The results support the hypotheses of the interdependence of opportunism level and age, marital status, motivation type, organization size, and salary improvement. It was found that education level, job profile and diploma compliance, and ownership do not affect alienation and opportunism. The research results can help develop corporate programmes to increase employees’ involvement in solving corporate problems and reducing opportunism.

Specifically, Cyber-Physical devices often lack software quality, resulting in hard-to-maintain solutions, presenting deficiencies in important aspects of IoT, such as portability and security. Software quality is of great importance to a solution’s long-term success, this work describes the proposal of a framework that aims to aid in the developing of these solutions, applying a Model-Driven inspired methodology.
High Frequency of Class I and II Integrons and the Presence of aadA2 and dfrA12 Gene Cassettes in the Clinical Isolates of Acinetobacter baumannii from Shiraz, Southwest of Iran
Authors: Khoramrooz Seyed Sajjad , Eslami Saba , Motamedifar Mohammad , Bazargani Abdoolah , Zomorodian Kamiar
Published: January 2022

Background: Acinetobacter baumannii is a global concern that causes healthcare-associated infections due to multidrug resistance against commercially available antimicrobial agents. Objectives: The present study was conducted to determine the antimicrobial susceptibility of A. baumannii isolates from clinical specimens in Shiraz, Iran. In addition, the possible relationship of susceptibility patterns with the presence of integrons and related gene cassettes is investigated. Methods: Acinetobacter baumannii isolates were collected, and their susceptibility to various antibiotics was tested using the Kirby-Bauer disk diffusion method. Moreover, molecular analysis were performed to detect the presence of the OXA-51-like gene, as well as class I, II, and III integrons, and associated gene cassettes. Results: The majority of isolates were resistant to imipenem (99.4%), piperacillin (98.2%), gentamycin (98.2%), meropenem (97.7%), ceftazidime (95.4%), amikacin (95.4%), and trimethoprim-sulfamethoxazole (90.8%). All strains showed multidrug resistance to the tested antibiotics. The distribution analysis of integrons genes revealed that 90.2, 72.4, and 12.1% of the isolates carried intI1, intI2, and intI3 genes, respectively. Moreover, two types of prevalent gene cassettes, including aad and dfr, were detected in class 1 integron-carrying strains. Conclusions: The current study showed the high prevalence of A. baumannii isolates harboring integrons in our investigated medical center, which may indicate the distribution of multidrug resistance events. The different gene cassette arrays highlight the remarkable role of geographical issues in disseminating multidrug-resistant (MDR) isolates. This could be attributed to distinct therapeutic interventions in different areas. The results demonstrate the necessity of continuous surveillance to prevent the distribution of multidrug resistance among A. baumannii strains in Iran.

Efeitos da sazonalidade sobre a fenologia e a fisiologia de Parkia platycephala Benth (Fabaceae, Caesalpinioideae) em área de Cerrado
Authors: Lacerda Valdelice Oliveira , Mapeli Ana Maria
Published: January 2022

Devido à sua natureza séssil, as plantas desenvolveram diversos mecanismos para manter sua reprodução e se defender em condições estressantes. Tanto o metabolismo primário quanto o secundário são afetados por mudanças ambientais nas diferentes fases de desenvolvimento vegetal. Sendo assim, é importante conhecer os mecanismos de defesa e resistência às intempéries ambientais de plantas adaptadas às diversas condições ambientais, a exemplo de Parkia platycephala. Essa espécie é endêmica do Brasil e apresenta diversas potencialidades de uso para fins farmacológicos, forrageiro, madeireiro, ornamental e ecológico. Dessa forma, este trabalho se propõe a analisar a relação entre sazonalidade climática, fenologia e fisiologia de Parkia platycephala. O estudo foi conduzido em área de Cerrado sensu stricto, na região da Serra da Bandeira (12º05’S e 45º02’W), Barreiras, Bahia. As fases fenológicas de Parkia platycephala foram observadas mensalmente, seguindo a metodologia de Fournier. O material vegetal (folhas) para as análises fisiológicas foi coletado dos mesmos indivíduos selecionados para fenologia, dos quais foram quantificados pigmentos fotossintéticos, teor de fenóis totais, atividade antioxidante, teor de açúcares solúveis totais (AST), açúcares redutores (AR) e açúcar não redutor (ANR). Parkia platycephala apresentou padrão vegetativo semidecidual sazonal e um padrão reprodutivo anual. A baixa disponibilidade hídrica foi o fator ambiental que mais afetou os processos fisiológicos, diminuindo a produção de clorofila a e carotenoides e promovendo o aumento na produção de clorofila b, fenóis totais e carboidratos solúveis não estruturais. No geral, a atividade antioxidante não enzimática em Parkia platycephala foi alta, sendo 3,66 vezes superior ao ácido ascórbico (Vitamina C). Dessa forma, a espécie demostrou possuir mecanismos eficazes para manter seus processos fisiológicos ativos suportando a seca e a intensa insolação durante o ano, porém a produção de carboidratos é afetada por essas variações ambientais refletindo negativamente sobre as suas fenofases, principalmente sobre a fenofase reprodutiva.

As funções de afilamento são ferramentas úteis para estimar diâmetros de toras e volumes comerciais de madeira a quaisquer alturas, sendo de grande importância para os empreendimentos florestais que buscam a otimização do uso de suas florestas. Este trabalho teve como objetivo avaliar modelos de afilamento segmentados, não segmentados e modelos de forma variável para estudo do afilamento do tronco de árvores de Eucalyptus sp. Com uma base de dados proveniente de um plantio de Eucalyptus sp. localizado no sul do estado de São Paulo aos 6,3 anos de idade, os modelos de afilamento testados foram: os modelos não segmentados de Ormerod (1973) e de Schöepfer (1966), o modelo segmentado de Max e Burkhart (1976), e os modelos de forma variável de Muhairwe (1999), Methol (2001) apud Rachid et al. (2014) e de Kozak (2004). Os volumes reais foram calculados utilizando-se o método de Smalian. O modelo de Kozak (2004) obteve as melhores medidas de precisão para estimativa dos diâmetros, já a equação de Muhairwe (1999) demonstrou os melhores resultados gráficos de dispersão de resíduos para a mesma estimativa. Para a estimativa volumétrica, a equação que obteve os melhores resultados foi a proposta por Methol (2001) apud Rachid et al. (2014), com as melhores medidas de precisão e melhor comportamento gráfico, com menores tendências e dispersão mais concentrada dos resíduos.

Published: January 2022

Despite the uniqueness and reach of the flora from natural savannas in the Brazilian Amazon, and the existence of studies on its origin and diversity, there are no local studies associating floristic patterns with soil properties in savanna enclaves in the Amazon region of the state of Mato Grosso. Floristic composition and diversity were compared between a woody community from a rocky savanna inselberg in a transition region (RTS) between the two largest South American biomes (Cerrado-Amazon), and an enclave of rocky savanna in the Amazon (RAS), and the effects of soil properties were investigated. Floristic comparisons were also made between the two studied communities and two other rocky savanna communities near the Cerrado-Amazon transition. The flora and physical and chemical soil properties in twenty-five 20 × 20 m subplots (1 ha) in each community were sampled and georeferenced. An evident floristic distinction was found between the two studied communities, with low similarity values and a high number of indicator species. The observed and estimated richness and Rényi diversity profiles indicated lower species diversity in RAS than in RTS. Soils were found to be litholic, poorly drained, dystrophic, alic, extremely acidic, sandy and nutrient poor. Species composition and abundance was associated with soil properties in both communities. The clear difference in species composition and diversity between RTS and RAS seem to be shaped by soil properties, geographic isolation and floristic influence from the Cerrado and the Amazon. These results broaden the knowledge regarding the composition and diversity of woody plants of savannas in Amazonian enclaves and Cerrado inselbergs, and provide an important set of floristic and edaphic descriptors for the phytogeography of rocky savannas.

El astroturfing como una estrategia publicitaria engañosa y abusiva en las plataformas de mercado
Authors: Alves Fabricio Germano , Gardeta Juan Manuel Velázquez , Sousa Pedro Henrique da Mata Rodrigues
Published: January 2022

En el ámbito del comercio electrónico, antes del proceso de compra de un determinado producto/servicio, se suele informar al consumidor de las características de los bienes y, más aún, de sus evaluaciones por parte de terceros usuarios. En esta perspectiva, debido a esta urgencia por la evaluación/comentario de un bien en el mercado, el astroturfing puede convertirse en una vía para la inserción masiva de comentarios falsos o maliciosos sobre los propios productos del proveedor o los de los proveedores de la competencia. Así, el quid de la cuestión gira en torno a la disyuntiva entre la necesidad de innovación de la publicidad de los proveedores y el engaño de una herramienta como el astroturfing como una estratagema de creación de opinión masiva. Así, para demostrar cuáles son los límites legales para el desarrollo de esta práctica, se analizará la literatura jurídica pertinente y la literatura consumista. Para ello se utilizará el procedimiento metodológico hipotético-deductivo, a través de la investigación aplicada, con un objetivo descriptivo. No existe una disposición unificadora en cuanto a la regulación del astroturf en el sistema jurídico vigente, si se tiene en cuenta que se trata de un mecanismo relativamente nuevo de las plataformas de mercado. Se concluye, por lo tanto, que dicha práctica constituye publicidad engañosa en los términos del párrafo 1 del artículo 37 del Código de Protección del Consumidor, y abusiva en los del artículo 36, caput, del mismo Código, debido a que induce a error al consumidor y viola directamente el principio de identificación de la publicidad.

The main idea of this paper is to present the modeling and simulation of an individual 5DOF degrees of freedom robotic arm. The main axis of the modeling design will be up to the branch of science that makes up Mechatronics. The methods that have been used for the 3D model construction are presented as well as the methods for the simulation. The kinematics problem for the robot system under study is elaborated. Both forward and inverse kinematics is addressed in detail. The CAD model design is also presented. The model parameters are defined for the 3D model and the parameters are used as a base to diverge for the real system. thanks to CAD model translation to SimMechanics model, there is no need for the dynamic equations of motion derivation. The model in SimMechanics is adjusted properly for the trajectory tracking simulation. Several simulations are presented to validate the kinematics solution and the dynamics requirements for the motion. The results presented in the article shows the effectivity of the new softwares in modeling and control of engineering systems.

Authors: Roh Seung Myeong , Eun Byung Wook , Seo Ji-Young
Published: January 2022

Purpose: This study investigated the impact of coronavirus disease 2019 (COVID-19) on body mass index (BMI) of children and adolescents.Methods: From May to July 2020, the obesity rate of children and adolescents was compared retrospectively to the corresponding rate in the same period in 2019. The change in height, weight, and BMI of the girls who received a gonadotropin releasing hormone agonist (GnRHa) for precocious puberty (n=53) and the controls (n=31) who visited a growth clinic for early breast budding but were not treated with GnRHa in the first half of 2020 were compared to the corresponding change in the first half of 2019 using a paired t-test.Results: The rate of overweight or obesity in new outpatients (n=113, 83 girls, 30 boys) who visited growth clinics from May to July 2019 was 25.3% for girls and 23.3% for boys. The corresponding rate for the same period in 2020 (n=201, 153 girls, 48 boys) was 31.4% for girls and 45.8% for boys. There was a significant increase in the rate of overweight or obesity. The BMI of the GnRHa treatment group increased significantly from May to July 2019 than during the same period in 2020 (P<0.01). There was no significant difference in BMI between those periods in the control group.Conclusion: During the social distancing period, the incidence of obesity was higher in boys than in girls. The obesity rate in girls who visited the growth clinic for early breast budding during routine follow-ups did not increase.

Published: January 2022

Childhood adrenocortical carcinoma (ACC) is a rare disease that is mostly linked to familial cancer syndrome. Although the prevalence of ACC is extremely low in children, it is clinically important to diagnose ACC early because age and tumor stage are closely related to prognosis. From this perspective, understanding the underlying genetics and possible symptoms of ACC is crucial in managing ACC with familial cancer syndromes. In this report, we present the case of a 3-year-old girl who initially presented with symptoms of precocious puberty and was later found to have ACC by imaging analysis. On genetic analysis, the patient was found to have a MEN1 gene mutation. MEN1 mutations are found in patients with multiple endocrine neoplasia type 1 (MEN1), usually precipitating multiple endocrine tumors, including pituitary adenoma, parathyroid hyperplasia, and adrenal tumors. Although MEN1 mutation is usually inherited in an autosomal dominant manner, neither of the patient’s parents had the same mutation, making hers a case of sporadic MEN1 mutation with initial presentation of ACC. The clinical course and further investigations of this patient are discussed in detail in this report.
Pediatric management challenges of hyperglycemic hyperosmolar state: case series of Korean adolescents with type 2 diabetes
Authors: Lee Sumin , Yoo Sukdong , Yoon Ju Young , Cheon Chong Kun , Kim Young A
Published: January 2022

The hyperglycemic hyperosmolar state (HHS) is considered the most fatal complication of type 2 diabetes mellitus (DM). The number of case reports describing pediatric HHS has increased recently in parallel with obesity and the prevalence of type 2 DM in pediatric patients. In this study, we investigated the patient characteristics and outcomes of HHS in 9 adolescents with obesity and type 2 DM. Almost all patients exhibited mixed clinical features of HHS and diabetic ketoacidosis (DKA), including characteristics such as hyperosmolality and ketoacidosis. These features made definitive diagnosis difficult; 5 out of 9 patients were initially diagnosed with DKA and were treated accordingly. Patients who were initially diagnosed with HHS received a more vigorous and appropriate fluid replacement than other patients did. No patients died, although 3 exhibited complications, such as arrhythmia, acute kidney injury requiring renal replacement therapy, rhabdomyolysis, and acute pancreatitis. Hyperosmolality with consequent severe dehydration is considered a significant factor contributing to the outcomes of patients with HHS. Therefore, early recognition of hyperosmolality is crucial for an appropriate diagnosis and adequate fluid rehydration to restore perfusion in the early period of treatment to improve patient outcomes for this rare but serious emerging condition in pediatric patients.

Agrarian Reform in Indonesia: Analyze Concepts and Their Implementation from a Governance Perspective
Authors: Kartodiharjo H , Cahyono E
Published: January 2022

Analysis of the relationship between inequality, agrarian reform and corruption as well as public administration reform has not been discussed, both in terms of the formation and implementation of agrarian reform in Indonesia. This article aims to explore the concept and implementation of agrarian reform, as well as the influence of governance conditions in the management of natural resources in the implementation of agrarian reform. With the characteristics of agrarian issues in Indonesia, land administration and those related to the implementation of redistribution of benefits from the use of natural resources need to be strengthened with appropriate concepts or theories, including public information disclosure as a fulfillment of substantive and deliberative implementation of democracy. In addition, by referring to experiences in other countries, agrarian reform needs to be carried out by reducing the level of clientelism and implemented through a number of corruption prevention and prosecution programs, especially in the fields of land and other natural resources.

China’s innovation-based approach in the fight of Covid-19. An estimation of China’s impact for global health to come
Authors: Perkuhn Josie-Marie
Published: January 2022

When the infectious coronavirus SARS-CoV-2 broke out it resulted in a global crisis. In the fight of Covid-19, China’s government relied on its strength to apply new technologies, i.e. for controlling and containment of the virus by tracing and tracking Chinese citizens. Relying on the trajectory of industrialisation, China has pursued a path of innovation. While it is reasoned that China’s advantage might have origin in the experience of the SARS outbreak almost two decades ago, this article argues that mainly China’s innovation- driven climate has favoured the application of new technologies in combatting the current crisis. Based on the innovation-driven trajectory this article explores China’s pathway out the corona crisis and how this might strengthen China’s role in global health governance. In order to pursue this aim, this article explores several areas, in which the next generation of technologies, such as AI-based diagnostic or intelligent robots were applied and concludes with an outlook based on the formulated political agenda, strategic considerations and initial international cooperation regarding China’s impact for global health.
Factors Affecting Profitability of Insurance Companies. Evidence from Kosovo
Authors: Ahmeti Yllka , Iseni Etem
Published: January 2022

Profitability expresses the ability to make a profit from all the business activities of the company. It shows how efficiently management generates profit by utilizing all available resources. This paper examined the effects of specific company factors, namely independent variables such as: liquidity, company size, company age, tangible asset, leverage, company capital and growth of com-pany, on profitability represented by return on assets (ROA) and net profit margin (NPM) as a dependent variable. The sample in this study includes eleven insurance companies for the period 2015 - 2020. The regression results indicate that size, leverage and age of company, have significant effects on the ROA. Meanwhile in NPM of insurance companies in Kosovo size of company and firm growth have significant effects.
The criminal liability of the medical team considering the recent orientation of the Italian Court of Cassation
Authors: Furramani Emanuela , Bushati Rrezart
Published: January 2022

This article aims to analyze the thematic of medical team liability considering the recent Italian Supreme Court case-law, highlighting the various problems linked to the identification of the responsibility of each member of the team. The participation of several subjects in the execution of medical treatment makes the question of criminal liability very complex, especially when it comes to inauspicious events, such as injuries or death, occurring during medical treatment. The question concerns the exact identification of the duty of care and vigilance of the medical team and whether this duty is in line with the principle of individual criminal responsibility guaranteed by Article 27 of the Italian Constitution. In this regard, the case-law has elaborated the so-called “principle of reasonable confidence”, according to which the division of labour that belongs to each member should involve a delimitation of his responsibility, limited only to what is within his competence, except in case of the person who organizes, directs, and controls the team. Precisely, based on this principle, the Italian Supreme Court in 2018 reasserted that in the medical team is necessary to identify the role played by each member, thus avoiding resorting to objective responsibility.
Global organization of neuronal activity only requires unstructured local connectivity

Published: January 2022

Modern electrophysiological recordings simultaneously capture single-unit spiking activities of hundreds of neurons spread across large cortical distances. Yet, this parallel activity is often confined to relatively low-dimensional manifolds. This implies strong coordination also among neurons that are most likely not even connected. Here, we combine in vivo recordings with network models and theory to characterize the nature of mesoscopic coordination patterns in macaque motor cortex and to expose their origin: We find that heterogeneity in local connectivity supports network states with complex long-range cooperation between neurons that arises from multi-synaptic, short-range connections. Our theory explains the experimentally observed spatial organization of covariances in resting state recordings as well as the behaviorally related modulation of covariance patterns during a reach-to-grasp task. The ubiquity of heterogeneity in local cortical circuits suggests that the brain uses the described mechanism to flexibly adapt neuronal coordination to momentary demands.

Efforts to eradicate tuberculosis are largely threatened by drug-resistant tuberculosis, particularly, multidrug-resistant tuberculosis (MDR-TB). Screening and identification potential biomarkers for MDR-TB is crucial to diagnose early and reduce the incidence of MDR-TB.

Methods

To screen the differentially expressed long non-coding RNAs in MDR-TB, the lncRNA and mRNA expression profiles in serum derived from healthy controls (HCs), individuals with MDR-TB and drug-sensitive tuberculosis (DS-TB) were analyzed by microarray assay and 10 lncRNAs were randomly selected for further validation by reverse transcription-quantitative real-time PCR(RT-qPCR). The biological functions of differentially expressed mRNAs as well as relationships between genes and signaling pathways were investigated using Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG), respectively.

Results

A total of 353 differentially expressed lncRNAs (312 upregulated) and 202 mRNAs (99 upregulated) were found in the MDR-TB group compared to HCs. And compared with the DS-TB group, 442 differentially expressed lncRNAs (115 upregulated) and 190 mRNAs (87 upregulated) were found in the MDR-TB group. The expression levels of lncRNA n335659 were found to differ significantly between each group by RT-qPCR. Compared with DS-TB group, the GO analysis showed that the differential mRNAs were mainly enriched in the processes associated with the detection of the chemical stimulus, the regulation of mRNA metabolic process and neutrophil activation in the MDR-TB group; the KEGG analysis indicated that the differential mRNAs between DS-TB and MDR-TB were mainly enriched in proteasome and Notch signaling pathway, which might reveal a fraction of the mechanism of MDR-TB. The discovery of the serum lncRNA n335659 might serve as a potential biomarker for MDR-TB and Notch signaling pathway provided a new clue for the investigation of the pathological mechanism of MDR-TB.

Digital marketing platforms have recently played a crucial role in hotel marketing and customer interaction strategies. Hotel managers have understood that hotel customers today and future rely increasingly on digital media use. However, the adoption of digital marketing tools appears to be relatively low in listed hotels in Sri Lanka due to unfamiliarity with digital marketing and not being confident in investing in digital marketing tools in achieving the expected financial and non-financial results. A considerable number of research has been carried out throughout the world on digital marketing and business performance; however, a limited study has been conducted in Sri Lanka to evaluate the influence of digital marketing tools on listed hotels’ financial performance. This research fulfills the above gap by measuring the impact of digital marketing tools on the financial performance of Sri Lankan-listed hotels. The study population consists of thirty-seven (37) listed hotels in Colombo Stock Exchange, and the entire population was taken as the sample. The dependent variable used to study the financial performance is the Return on Equity. Digital marketing tools such as social media and mobile marketing are independent variables considered in this study. A self-administrated structured questionnaire was circulated to the marketing professionals. After analyzing the responses using correlation analysis and regression analysis, it was revealed that social media and mobile marketing have a significant positive impact on the hotel’s financial performance. The findings are useful in reducing ambiguity and confusion about financial and non-financial outcomes based on digital marketing tools.

Aims: Conservation agriculture has been recommended as an option to mitigate climate change impact when practicing conventional, to ensure sustainability and food security This study examined the effect of conventional tillage (CT) and no tillage (NT) on mineral elements uptake, total phenolic content (TPC) and total flavonoid content (TFC) of barley.

Study Design:  Split-plot design was applied for this study.

Place and Duration of Study: The experiment was conducted in ESAK station (Boulifa, kef, North West Tunisia) during 2016/2017 cultivation year.

Methodology: Mineral elements uptake, total phenolic content (TPC) and total flavonoid content (TFC) of barley were studied as affected by conventional tillage (CT) and no tillage (NT) for tillering and grain filling stages.

Results: The results showed that tillage practices (T) had no significant effect on mineral uptake, total phenolic content and total flavonoids content under rainfed conditions. The stage (S) had showed significant effects on P, Ca and Na amounts for both tillage practices when it had no effect on K amount. The interaction T x S had no significant effect on mineral elements concentrations and TFC. However, this interaction had affected TPC significantly. Phosphorous (P) showed high significant positive correlations with Ca and Na. In addition, P presented high significant negative correlations with TPC and TFC. For partial correlation based on Tillage practices, similar correlations values were noted.  Considering the partial correlation based on plant stages, no significant correlations had been noted.

Conclusion: This work enlarges our knowledge on barley mineral elements uptake, TPC and TFC as influenced by tillage practices aiding decision makers in increasing no tillage adoption in Tunisia under rainfed conditions.

Micronutrients, particularly Zinc (Zn), play a vital role in the growth and development of plants due to its catalytic effect on many metabolic processes. However, the varietal responses to growth and yield vary significantly. A screening experiment was conducted to know the growth and yield response of six capsicum hybrids viz., Indra, Priyanka, Inspiration, Massilia, Bachata and Local green with two levels of ZnSO4 (with and without  ZnSO4) as basal soil application. The growth and yield attributes at harvest stage was recorded. The dry matter production (DMP) and fresh fruit yield was also noted for all the six hybrids. Results revealed that, Zn fertilisation significantly improved the plant height, root growth, fruit development as well as fresh fruits yield. Higher plant height (83 cm), root length (37 cm), root volume (13 cc), fruit numbers, fruit weight (15 and 133g), fruit length, girth, pericarp thickness (9.17, 8.25 and 0.67 cm), DMP (65.0 g pot-1) as well as fresh fruit yield (4.70 kg pot-1) were observed with Indra followed by Inspiration and Bachata. Lesser response for the Zn application was noticed with the local green hybrid for various growth and yield traits. Indra was found to be highly responsive to Zn fertilisation while Inspiration, Bachata, Massilia, and Priyanka were medium responsive and local green hybrid was observed to be less responsive to Zn fertilisation.

Background: Soup condiments are edible food items which are added to dishes, used as thickeners for soup and also as food supplements such as sauce that is added to food to impact specific flavours. They are abundantly produced in Nigeria especially in North-Western part of the country.

Aims: The aim of this research was to determine the proximate composition and parasitic contamination of Hibiscus sabdariffa seed cake (Roselle seed cake): a soup condiment produced by North-Western Community, Nigeria.

Study Design:  Samples were purchased and collected at random from the markets of different places in the study areas, aseptically placed into polythene bags and labelled correctly.

Place and Duration of Study: The study was conducted in Zuru and Sakaba Local Government Areas of Kebbi State, North-Western Nigeria.

Methodology: The proximate analysis carried out include: moisture determination, ash determination, determination of crude protein, lipid determination, fibre determination and carbohydrate estimation by difference. The protozoa present in the samples were identified by direct microscopy.

Results: The proximate composition of Hibiscus sabdariffa seed cake in the study areas had a very high level of carbohydrate content (52.44±1.03%), followed by the moisture content (15.43±0.10%), lipid content (12.00±0.50%), fibre content (11.16±0.58%), ash content (7.80±0.05%) and crude protein content (1.16±0.13%) which was the lowest. The highest prevalence rate of the identified protozoa was recorded in Entamoeba histolytica 2(50.0%) followed by Giardia lamblia 1(25.0%) in Zuru Local Government Area. No protozoa was seen in Zuru sample 0(0.0%). In Dabai sample, Giardia lamblia was seen 1(25.0%). While in Bedi sample, Entamoeba histolytica 2(50.0%) was seen which was the most prevalent. However, in Sakaba Local Government Area, a total of nine protozoa was seen and all were Entamoeba histolytica. Dirin-Daji sample showed 1(11.1%), Doka 2(22.2%), Dankolo 2(22.2%), Janbirni 1(11.1%), Laraba 1(11.1%) and Makuku 2(22.2%) respectively.

Conclusion: It can be concluded that the available carbohydrate and moisture contents were higher than other parameters and the local soup condiments were heavily contaminated with protozoa and Entamoeba histolytica had the highest prevalence which can cause serious food-borne diseases in humans in the study areas. Finally, the need to apply good manufacturing practices in processing the condiments in the study areas and North-Western Nigerian Community as a whole is highly recommended.

The researcher conducted a quasi-experimental study on menstruation and menstrual hygiene among the adolescent girls at primary girls’ school (ajarpura kanyasala) under Anand district Gujarat. The study was intended to see the impact of a structured teaching programme in improving the knowledge of adolescent girls specific to rural areas. The objectives of the study were to assess the existing knowledge, to develop a structured teaching program on menstruation and menstrual hygiene, to assess the knowledge after implementation of structured teaching programmes and to find out the association between the knowledge score of the respondent with the selected demographic variables. The quantitative research approach was used with one group pre-test post-test- quasi experimental research design. The sample of 50 was drawn using probability sampling technique. The tool used was structured knowledge questionnaire. The result shows that majority of the respondents were (92%) in the age group of 12-13 years, most of the respondents (90%) were Hindu religion, the family income for most of the respondent (64%) falls in between Rs. 2000-3000, almost half of the respondents were having an elder female sibling (52%), and initial assessment reveals most of the respondents were (82%) having some knowledge about menstruation and menstrual hygiene. The finding shows significant difference between mean pre-test score (15.56) and post test score (27.80) which also reveals the importance of right information is needed to this group to discard any irrelevant practices. The association with certain demographic variables (age, family income, elder female sibling, information about menstruation) also established at 0.05 level of significance.
