Authors: Tidke Bharat , Mehta Rupa G. , Rana Dipti P. , Jangir Hullash
Published: December 2019

Social media data (SMD) is driven by statistical and analytical technologies to obtain information for various decisions. SMD is vast and evolutionary in nature which makes traditional data warehouses ill suited. The research aims to propose and implement novel framework that analyze tweets data from online social networking site (OSN; i.e., Twitter). The authors fetch streaming tweets from Twitter API using Apache Flume to detect clusters of users having similar sentiment. Proposed approach utilizes scalable and fault tolerant system (i.e., Hadoop) that typically harness HDFS for data storage and map-reduce paradigm for data processing. Apache Hive is used to work on top of Hadoop for querying data. The experiments are performed to test the scalability of proposed framework by examining various sizes of data. The authors' goal is to handle big social data effectively using cost-effective tools for fetching as well as querying unstructured data and algorithms for analysing scalable, uninterrupted data streams with finite memory and resources.
Healthcare Automation System by Using Cloud-Based Telemonitoring Technique for Cardiovascular Disease Classification
Authors: Halder Basudev , Mitra Sucharita , Mitra Madhuchhanda
Published: December 2019

This paper illustrates the cloud-based telemonitoring framework that implements healthcare automation system for myocardial infarction (MI) disease classification. For this purpose, the pathological feature of ECG signal such as elevated ST segment, inverted T wave, and pathological Q wave are extracted, and MI disease is detected by the rule-based rough set classifier. The information system involves pathological feature as an attribute and decision class. The degree of attributes dependency finds a smaller set of attributes and predicted the comprehensive decision rules. For MI decision, the ECG signal is shared with the respective cardiologist who analyses and prescribes the required medication to the first-aid professional through the cloud. The first-aid professional is notified accordingly to attend the patient immediately. To avoid the identity crisis, ECG signal is being watermarked and uploaded to the cloud in a compressed form. The proposed system reduces both data storage space and transmission bandwidth which facilitates accessibility to quality care in much reduced cost.

Authors: Eskelund Karsten , Grunfeld Helena , Des Phal
Published: December 2019

Using assessment criteria from the A.T. Kearney global services location index, the authors explore Cambodia's competitiveness in the global IT outsourcing market (ITO), identifying how the country could become more competitive. The findings are discussed from the perspective of the Heeks and Nicholson software export success model, assessing Cambodia from a national competitiveness perspective. With ITO's export revenue and skills development potential, it is important to understand why Cambodia is not considered a significant ITO destination and what the country can do to increase its competitiveness in this area. This paper is useful for practitioners considering Cambodia as an ITO destination, for the Cambodian government as a guide to policy measures for increasing its competitiveness as well as for IT researchers, who could complement the study with primary data and development the conceptual approaches applied in this article, whether in Cambodia or other developing countries.

Authors: Ward Graham Bernard , Adendorff Chris
Published: December 2019

The purpose of this study is to contribute to the promotion and development of entrepreneurship in South Africa. The objective was to develop and test a model which could be used in the development and training of entrepreneurs. Officially, 27.7% of South Africans are unemployed. This is especially important in that, the South African economy is battling to recover from the world economic crisis of 2009/10, putting pressure on government to alleviate growing unemployment and curtail social unrest. The study comprised of a literature review as to how globally entrepreneurs are developed, culminating in the perceived success factors for entrepreneurship. These factors were then tested on small business owners operating in South Africa. The authors argue that, in order to successfully develop entrepreneurs: 1) 99% of entrepreneurs will need to have the required socio-emotional skills; 2) 99% of entrepreneurs will require mentorship; and 3) 95% of entrepreneurs will require access to start-up capital.

Authors: Brooks Stoney , Wang Xuequn , Schneider Christoph
Published: December 2019

In today's technology-centric world, people are becoming increasingly dependent on the Internet. The most common use of the Internet is through social media, which is used to communicate, share, collaborate, and connect. However, continued usage of a hedonic system can be linked with compulsion or addiction. Since problematic usage/behaviors can lead to negative outcomes, this study aims to determine differential effects of Internet and social media addictions on social media-related technostress. This is examined in two different cultures: The U.S. and China. The results support the association between the Internet and social media addictions with increases in social media-related technostress. Additionally, these effects are moderated by culture. Implications for research and practice are discussed along with future directions for this stream.
Commentary on International Experience Opportunities for Athletic Training Students: A Perspective from the National Athletic Trainers' Association International Committee
Authors: Wright Cynthia J.
Published: December 2019

Context

International experiences (eg, study abroad, international service projects) have many benefits, including increasing cultural sensitivity, that can enhance athletic training student development. However, international experiences directly related to athletic training may be limited or hard to identify.

Objective

To outline current and upcoming resources available through the work of the National Athletic Trainers' Association International Committee (IC) related to athletic training international experience opportunities.

Background

The IC collaborated with the Commission on Accreditation of Athletic Training Education to ask about international experiences available in accredited programs in the 2016–2017 annual report.

Synthesis

Data were analyzed from all accredited programs (N = 410).

Results

Data indicated that athletic training–specific international experiences are available at a lower rate (0%–10.6% of programs) than general university-sponsored international experiences (15.4%–84.4% of programs). Information on athletic training student and faculty involvement is limited; at least 1 student participated in 39.5% to 61.5% of programs, and at least 1 faculty member participated in 15.4% to 23.4% of programs.

Recommendation(s)

Future research should identify and describe current international experience opportunities, as well as identify strengths, challenges, and priorities for developing and expanding international opportunities for athletic training students.

Conclusion(s)

With the globalization of athletic training, emphasis on providing culturally competent care, and undergraduate opportunities created by the degree transition, it seems an opportune time to encourage international experiences for athletic training students. Current and future IC resources aim to provide guidance to students and faculty interested in international experiences.
Short-Term, Faculty-Led Study Abroad Program in Japan
Authors: Shibata Daisuke
Published: December 2019

Context

Although cultural competencies in athletic training education exist, there are limited international athletic training educational opportunities available. Study abroad experiences help students gain international and multicultural perspectives. The lack of study abroad opportunities is more pronounced in non–English-speaking countries.

Objective

The purpose of this article is to describe experiences with developing and conducting a short-term, faculty-led study abroad program in Japan. Essential elements and recommendations based on the study abroad program are interwoven throughout the article.

Background

The diversity in the United States and among the collegiate student-athlete population has increased. However, the population of athletic training professionals does not match this diversity. This mismatch has increased attention to the demand to find ways to nurture cultural competencies in athletic trainers. Simultaneously with changes in the United States, growth of the athletic training profession and athletic training educational programs is noticeable in Japan and other non–English-speaking countries. A well-designed study abroad program can expose students to the unique perspectives of athletic training and/or related health care professions and nurture cultural competency.

Recommendations(s)

A short-term, faculty-led study abroad program should include an assistant and local facilitator, multiple site visits, at least a day without guidance from the program, an adequate balance between academic and cultural activities, program dinners, opportunities for students to present and share their experiences, and a focus on keeping the trip safe.

Conclusion(s)

The short-term, faculty-led study abroad program in Japan offered unique opportunities for athletic training students to gain knowledge of and an appreciation for athletic training in diverse cultures and to incorporate these experiences into their future personal and professional practice. Further information and data are required to provide an optimum education for students to learn and apply cultural competencies as health care professionals.
Signature Pedagogies in Athletic Therapy Education
Authors: King Colin D. , MacKinnon Gregory
Published: December 2019

Context

Developing an understanding of the signature pedagogies in athletic therapy education may help to promote greater pedagogical development opportunities and encourage meaningful reflection for educators.

Objective

To gain an understanding of the perceived level of pedagogical knowledge in Canadian athletic therapy educators and how they developed such knowledge.

Design

Sequential explanatory mixed-methods.

Setting

Seven undergraduate Canadian Athletic Therapists Association–accredited institutions

Patients or Other Participants

Twenty-one athletic therapy educators (16 women, 5 men) responded to the initial questionnaire; 15 athletic therapy educators (11 women, 4 men) participated in individual phone interviews.

Main Outcome Measure(s)

An initial questionnaire was designed to explore general pedagogical knowledge in athletic therapy educators and how familiar participants were with different teaching strategies. Emergent trends from these questionnaires were used to design a specific interview schedule. Phone interviews further explored the institutional, personal, student, and cultural factors that affected the selection of different pedagogical approaches. Findings from the questionnaires and interviews were combined to identify participants' pedagogical approaches to teaching in an athletic therapy setting.

Results

A pedagogical distinction was observed, dividing the sample into 2 groups. One group used a traditional, passive lecturing format, and the other, more innovative pedagogies. Educators who followed traditional teaching practices were less likely to know about different pedagogies or understand how these strategies could contribute to more effective instruction. The other group of educators appreciated the use of different pedagogies and explained how different teaching strategies could be incorporated to enhance learning in the athletic therapy curriculum.

Conclusions

On the basis of these findings, Canadian athletic therapy educators would benefit from more formalized pedagogical training and/or development. These formalized opportunities could familiarize educators with innovative pedagogical strategies while also preparing them with the necessary skills required to self-evaluate their own teaching approaches.
Professional Presentations for an International Audience
Authors: Konin Jeff G. , Denegar Craig R.
Published: December 2019

Context

The opportunity to deliver a professional presentation to an international audience is a privilege. As with all other presentations, preparation and planning are essential components for a successful outcome. The difference between a diverse international audience and a homogeneous audience of the same background as the speaker requires consideration of additional factors associated with relevant delivery of the content matter. Recognition and integration of cultural differences, language barriers, and delivery expectations are critical to the creation and conveyance of one's presentation.

Objective

This article will share advice for preparing for and delivering presentations to an international audience.

Data Source

Factors to consider when preparing a platform-style presentation include knowing the cultural background of audience members, the speed and tone of one's delivery, the appearance of slides, the use of hand gestures, and the integration of appropriate terminology. The process of speaking through an interpreter and additional methods that have been proven to be effective in the delivery of an international presentation will also be identified.

Conclusion

One can never have enough experience, as each presentation to a diverse international audience may be vastly different.

Hepatitis A-associated cholestasis and aplastic anemia
Authors: Elarabi Amal , Saad Zinab , Sagher Fauzi
Published: December 2019

Hepatitis A virus (HAV) infection in children is typically an acute, self-limited illness associated with general, nonspecific symptoms. Prolonged cholestasis is a rare atypical form of HAV infection that is characterized by serum bilirubin levels higher than 10 mg/dl for more than 12 weeks. Aplastic anemia is another very rare complication of HAV. We report the case of an 11-year-old male with blood group O Rh positive who developed cholestasis followed by aplastic anemia postfulminant HAV infection. Liver function tests rapidly responded to a short course of steroid treatment. The patient had a sickle cell trait and a variant of ABCB11 gene. There was no history of traditional herbal treatment, but we noticed several cautery marks. Immunosuppressive medication was started for aplastic anemia, and he is listed for urgent bone marrow transplant. This is the first reported case of prolonged cholestasis followed by aplastic anemia complicating fulminant HAV infection in a Libyan adolescent.
Procalcitonin and other inflammatory markers in patients with sepsis and septic shock: A single-center experience
Authors: George Saibu , Thomas Merlin , Rafiqui Sumaira , Al Maslamani Muna , Elzouki Abdel-Naser
Published: December 2019

Objective: The objective of the study was to compare the diagnostic value of serum procalcitonin (PCT), C-reactive protein (CRP), lactic acid, and white blood cells (WBC) as markers of sepsis in critically ill patients in the main tertiary hospital in Qatar. Materials and Methods: The PCT levels and other inflammatory markers (CRP, lactic acid, and WBC) were retrospectively reviewed in 137 consecutive adult patients with a suspected diagnosis of sepsis who admitted to the Internal Medicine inpatient service (i.e., Medical Wards and Medical Intensive Care Unit) at Hamad General Hospital, Qatar. The serum PCT was measured by chemiluminescence immunoassay and the results were compared with commonly used inflammatory markers between the patients with and without proven sepsis. Results: A significantly higher PCT level was observed among patients with severe sepsis and septic shock compared to those without sepsis (19.34 ± 50 and 25.91 ± 61.3 vs. 4.72 ± 10, respectively; P = 0.011). No significant differences were found in CRP and WBC between these groups. Nonsurvivors of both septic and nonseptic groups had a mean PCT level of 22.48 ± 8.26 significantly higher than that measured in survivors of both the groups (P = 0.01), a difference not evident in other inflammatory parameters. Conclusions: PCT is a highly efficient inflammatory laboratory parameter for the diagnosis of severe sepsis and septic shock, but WBC and CRP levels were of little value. PCT value assists in the diagnosis of septic shock, hence supporting appropriate disposition of patients. The levels of PCT also have prognostic implications with regard to mortality suggesting intensification of antibiotic therapy and supportive measures including appropriate family counseling.

Authors: Shamir Muhammad Farasat , Fayyaz Iffat
Published: December 2019

В рамках модифицированной $f(R)$-гравитации для статического сферически-симметричного пространства-времени исследуется возможность образования анизотропных компактных звезд. Для определения неизвестных метрических коэффициентов используются данные о массах и радиусах компактных звезд 4U 1820-30, Cen X-3, EXO 1785-248 и LMC X-4. Для различных сил получено уравнение гидростатического равновесия. При анализе поведения звезд используется обобщенное уравнение Толмана-Оппенгеймера-Волкова. Кроме того, проверяются условия регулярности, поведение показателя анизотропии, энергетические условия и устойчивость компактных звезд. Для анализа применяется эффективный тензор энергии-импульса в $f(R)$-гравитации. Показано, что в рамках модели $f(R)$-гравитации физическое поведение рассмотренных компактных звезд соотвествует общепринятым представлениям. Результаты согласуются с результатами общей теории относительности, которая является частным случаем $f(R)$-гравитации.
Presoja vloge zelenih in pozidanih površin pri zmanjševanju učinkov površinskega mestnega toplotnega otoka na podlagi podatkov daljinskega zaznavanja
Authors: KAPLAN Gordana
Published: December 2019

Hitra urbanizacija ima številne negativne vplive na okolje in zdravje ljudi ter pomembno prispeva h globalnemu segrevanju. Eden izmed teh vplivov so tudi mestni to- plotni otoki, ki jih povzroča človekova dejavnost in so opredeljeni kot temperaturne razlike med mestnimi in okoliškimi območji. Zaradi hitre urbanizacije v zadn- jih desetletjih se Skopje spoprijema z izjemno močnimi učinki mestnih toplotnih otokov. Za proučevanje vloge pozidanih in zelenih površin pri nastanku površinskega mestnega toplotnega otoka je avtorica uporabila satelitske podatke Landsat ETM+, na podlagi katerih je analizi- rala temperaturo tal, in posnetke satelita Planet Scope DOVE visoke ločljivosti, na podlagi katerih je analizirala pozidane in zelene površine. Za geostatistične analize je uporabila 17 naključno izbranih podobmočij v Skopju. Izsledki raziskave kažejo pomembno povezavo med mestnim toplotnim otokom in pozidanimi površinami ter močno povezavo med zelenimi površinami in območji, na katerih ni mestnega toplotnega otoka, kar kaže, da se lahko učinek mestnih toplotnih otokov pomembno zmanjša z dodatnimi zelenimi površinami. Eden izmed pomembnih izsledkov raziskave je, da idealno razmerje med deležem pozidanih in zelenih površin, pri katerem je učinek mestnega toplotnega otoka šibek, v nekaterih primerih pa ga celo ni, znaša 40 : 60. Nadaljnje raziskave bi se morale osredotočati še na druge dejavnike, ki lahko vplivajo na nastanek mestnega toplotnega otoka.

Published: December 2019

A new sample preparation procedure to determine seven organochlorine pesticides and seven polychlorinated biphenyls in environmental water samples by using a combination of ultrasonic-assisted solvent extraction and dispersive liquid-liquid micro-extraction was established, and the extracted analytes were analyzed by gas chromatography coupled with electron capture detector. Some parameters influencing the extraction efficiency were studied and optimized utilizing response surface methodology. Under the optimum extraction conditions, the method showed wide linear ranges with r2 > 0.9989 and low limits of detection and quantification between 0.16 ~ 2.17 μg/L and 0.53 ~ 7.16 μg/L, respectively. Enrichment factors (EF) were high and ranged from 63 to 116. Relative standard deviations (RSDs) for the extraction of 25 μg/L of each selected OCPs and PCBs were less than 10.2 %. The proposed method was successfully used for targets contaminations determination in different water samples. α-HCH, β-HCH and p,p’-DDE were found in lake water closed to farmland with concentrations of 2.56 μg/L, 4.44 μg/L and 4.74 μg/L, respectively, and other OCPs and PCBs were not found in the corresponding water samples. The relative recoveries of OCPs and PCBs from tap water, river water and lake water at spiking levels of 10 μg/L were in the range of 81.9 ~ 109.7 %, within a relative standard deviation of 1.7 ~ 11.8 %. The results revealed that the proposed method was well suited for the determination of trace amounts of target contaminations in liquid samples.

Authors: ALGHAMDİ Faisal , ALJAHDALİ Esraa
Published: December 2019

The root perforation, in spite of being taken as a challenging
accident in root canal treatment, has to offer favorable results when exposed
to appropriate therapeutic conduct and the usage of materials that have
convenient properties. The aim of the current review is to collect all updated
and available studies including imperative information concerning the use of
Mineral trioxide aggregate, EndoSequence root repair material and Biodentine in
the treatment of root perforation approaching some of the key properties for
treatment success. A search was performed in the two automated databases
(Google Scholar and PubMed use English-language literature) for this systematic
review, using specific inclusion and exclusion criteria and keywords. The
electronic search was done in December 2018 and update in June 2019. Our
inquiry uncovered Twenty-two studies that met the exclusion and inclusion
criteria. These studies investigated the use of MTA, EndoSequence ERRM and Biodentine
in the root perforation that happened during the endodontic treatment. It was
confirmed that there is no unanimity in this review concerning the material
that shows the best characteristics, once none of the materials discussed had
all the major properties higher than the others, this way it is required the
enforcement of further studies aimed at selecting the best characteristics of
the material suggested in the root perforation treatment.
Effect of Different Surface Treatments on the Repair of Aged Bulk-Fill Composites: An In Vitro Study
Authors: ŞİŞMANOĞLU Soner
Published: December 2019

Objectives: The aim of this in vitro study was to evaluate the efficiency of different surface treatments
on the microtensile bond strength (µTBS) of aged bulk-fill composite.Materials and Methods: Sixty bulk-fill resin-based
composite (RBC) specimens in 5 x 5 x 5 dimensions were prepared. After the
aging by thermal cycling for 5000 times between 5 and
55°C, substrate surfaces were abraded with SiC abrasive papers. Specimens
were divided into 6 groups according to the surface treatment protocol: no
surface treatment (control), control + Single Bond Universal (SBU; 3M ESPE)
application, phosphoric acid etching (PA) + SBU, hydrofluoric acid  etching (HF) + SBU, aluminum oxide air
abrasion (AlO) + SBU, and tribochemical silica coating (TSC) + SBU. Surface roughness values were measured in five different
directions using a contact profilometer (n=10). Then, specimens were repaired
with a conventional RBC. After the repair, bonded specimens were cut into 1 mm2
beams and µTBS values were determined until failure at a crosshead speed of 0.5
mm/min. Specimen surfaces after surface treatments were observed by SEM.
Data were analyzed using  ANOVA and Tukey
tests (p<0.05). Results: One-way ANOVA revealed significant difference
(p<0.001) among the surface
treatments. The lowest repair µTBS values were observed for the control group. SBU
application alone significantly improved repair µTBS values (p<0.001). The highest µTBS values
were obtained for the AlOand TSC, and HF followed. The surface
roughness ranking for the five surface treatment protocols was as follows: TSC
> AlO > HF > PA = Control.

Conclusions: Aged bulk-fill RBCs can be successfully
repaired if effective and safe repair protocol is chosen. The highest µTBS
values were obtained for the AlO and TSC. The use of universal adhesive alone is
promising to facilitate the repair of bulk-fill RBCs.
Emotions theory in Nietzsche: beyond traditional Dualism
Authors: Calbino Daniel
Published: December 2019

In recent years there has been the advance of theories aimed at broadening the reflection on emotions and influences on moral aspects. In the midst of this discussion, the essay aims to investigate Nietzsche's philosophical for the critique of the reason versus emotion. As results, it is pointed out that Nietzsche preceded empirical psychology in centuries. If studies in the field of neuroscience bring inferences from explanations of physiology in the rational, Nietzsche pointed out to these hypotheses, although by purely logical and rational means. In short, the innovations in the author's thinking contribute to dialogue with the emotion’s theory, as well as to counteract the ethical rationality superimposed on affects.

Authors: Madruga Elisângela Barbosa , Henning Paula Corrêa
Published: December 2019

Este artigo discute o cenário discursivo da atualidade no que tange a constituição de sujeitos por meio das tecnologias na educação formal, especificamente, os jogos eletrônicos. Sob esse viés as demandas sociais e econômicas são atendidas para garantir um amanhã ambientalmente responsável e próspero. Nessa perspectiva, considerando a realização de alguns tensionamentos acerca do tema, tomou-se como objetivo de pesquisa a identificação e análise dos ditos que são assumidos por professores da escola primária e reproduzidos em planos de aula. Treze planos de aula para crianças de 6 a 7 anos, produzidos por professores no jogo eletrônico Minecraft: Education Edition foram escolhidos como material de análise. Para a análise dos ditos utilizou-se como proposta teórico-metodológica a análise do discurso foucaultiana. Ao analisar os planos, verificou-se que 7 lições visavam uma aprendizagem baseada em projetos para desenvolver habilidades como colaboração, criatividade, pensamento crítico etc. Os planos abrangeram os anos 2016, 2017 e 2018. A análise discursiva apontou para a constituição de um sujeito proativo, dinâmico e flexível que se fundamenta num pensamento neoliberal, computacional e científico para a resolução de futuras situações problemas, entre elas as provocadas por uma crise ambiental.
Singularidade feminina no catolicismo: práticas formativas em um caminho permeado de “espinhos e rosas”
Authors: Dantas Maria José
Published: December 2019

A presente pesquisa lança um olhar sobre o papel da mulher na Igreja, sua singularidade, dignidade e particularidades, apresentando o cotidiano e as práticas educativas empreendidas por moças que escolheram o ambiente religioso católico como campo de atuação. Nesse sentido, o estudo investiga de modo específico as práticas formativas desenvolvidas no interior da Congregação das “Irmãs Teresinhas”, sobretudo no que diz respeito à atuação da Madre Valdelícia, Superiora Geral por mais de 30 anos. A análise foi realizada a partir dos pressupostos teóricos fundamentados na Nova História Cultural e na História da Educação e tem como base os conceitos de carisma, capital cultural e campo religioso de Pierre Bourdieu (1989, 1980, 2005, 2012), além de estratégia de Michel de Certeau (1994) e representação de Roger Chartier (1990, 2002). A metodologia utilizada consistiu em pesquisa bibliográfica, documental e realização de entrevistas. Dentre as fontes utilizadas estão diários, livros, cartas, crônicas da Congregação, recortes de jornais, certificados e os depoimentos orais. Conclui-se que, não obstante as várias dificuldades, denominadas “espinhos”, a Congregação e a Madre transitaram com êxito no campo religioso e educacional de Sergipe. Valdelícia construiu relações com personalidades e firmou-se, sendo respeitada e estimada por bispos, padres e demais autoridades eclesiais e civis. Além disso, por meio de sua atuação como professora, diretora e Madre Superiora, desenvolveu uma intensa atividade educativa e tornou-se uma personagem com muitas contribuições para a História da Educação Católica em Sergipe.

A influência do discurso filosófico de Nietzsche na reestruturação do conceito de eclesiologia na contemporaneidade
Authors: Pamato Saulo
Published: December 2019

Enquanto sustenta um relativismo radical, a pós-modernidade descontrói os conceitos fundamentais das visões tradicionais, rejeitando por completo uma visão única e correta de mundo. Se a concepção medieval lançou seu foco em Deus e a modernidade na realidade externa ao indivíduo, surge na contemporaneidade a centralidade na perspectiva humana líquida, fluida e oscilante. Com isso, não obstante o testemunho bíblico forneça fundamento irrefutável acerca do propósito de Cristo, surge no seio do evangelicalismo moderno um movimento que, embora envolto numa nova roupagem, visa trazer ao debate a validade da doutrina da eclesiologia, oferecendo juízo concernente a sua legitimidade. Cabe à Teologia Cristã em seu estudo crítico compreender a história e desenvolvimento das percepções lógico-filosóficas a fim de tornar relevante o conceito de igreja como instituição divina também no cenário atual.

The Awareness Level and Perception of Secondary School Physics Teachers towards Nanotechnology in Rivers State
Authors: Eseroghene Avwiri,
Published: December 2019

This paper adopted a descriptive design to investigate the awareness level and the perception of secondary school Physics teachers towards Nanotechnology in Port Harcourt Metropolis of Rivers State. The population of the study was 43 physics teachers comprising of 25 male and 18 female which was used from the 12 public secondary schools in Port Harcourt Metropolis in Rivers State. The instrument for the study was a self- made questionnaire titled, Nanotechnology Questionnaire on Awareness and Perception for Teachers (NQAPT) with a reliability of 0.85 obtained using Cronbach Alpha reliability formula. Two research questions and two null hypotheses guided the study. The research questions were answered using the criterion mean of 2.5 and standard deviation, while the null hypotheses were tested at 0.05 level of significance using t- test. The findings revealed that the awareness level of Nanotechnology among teacher was low and their perception towards nanotechnology was positive. There is no significant difference between the awareness level and perception of the concept of Nanotechnology among male and female senior secondary school Physics teachers. Based on these findings, it is recommended that more awareness on the concept of Nanotechnology be created among secondary school teachers through symposium and science teaching workshop in order to publicize the benefits of nanotechnology to the society.

Published: December 2019

The survey was carried out in 2017 main cropping season to support farmers for correct insect pest identification. Three Kebeles, Hallo, Sambaro and Herara with five farmer’s fields randomly selected. Ten representative plants were taken from each field. Data on mean larval density per plant, percentage leaf infestation and damage levels were assessed. Results from mean larval density per plant showed that significant difference between insect species (R2= 0.96, Pr (>|Z|=0.013) where the highest 1.55-2.30 was recorded from C. partellus. There was a significant difference between C. partellus and M. trapezalis; S. frugiperda and M. trapezalis in percentage leaf infestation (R2=0.75, Pr. (>|Z|=2e-16) where, the highest were recorded from C. partellus and S. frugiperda representing 50-90% and 40-90% respectively. From the above, C. partellus and S. frugiperda were at risk, as a result insecticide was recommended. M. trapezalis showed a lower infestation level so that hand picking was more economical than use of insecticide. Hence, registration and detail molecular identification will be needed as M. trapezals is the first record on maize crop in Ethiopia.
Prevalence of Schistosoma haematobium and Its Intermediate Hosts in Makurdi Metropolis

Introduction: Urinary Schistosomiasis (US) is a chronic water-borne infection caused by digenetic trematode belonging to the genus schistosoma, it is generally caused by Schistosoma haematobium. Bulinus globosus is a species of a tropical freshwater snail that acts as an intermediate host of Schistosoma haematobium. Aim: The study was aimed at ascertaining the prevalence of Schistosoma haematobium infection and to describe its intermediate hosts among school children in Makurdi.

Methodology: Snails were collected by hand picking and scooping net methods. An epidemiological survey research on urinary Schistosomiasis was undertaken from September to November 2017 among students that volunteered in the selected schools within Makurdi metropolis. A total of 97 freshwater snails were collected and 200 urine samples involving pupils aged between 5 to 18 years were collected and analyzed for the eggs of Schistosoma haematobium by microscopy using Urine Syringe Filtration Technique (USFT). Statistical analysis was performed using SPSS 20. Chi-square test was used to determine the significant difference between variables.

Results: Out of the 97 species of freshwater snails that were caught 41(42.3%) was Bulinus spp. Of the 200 urine samples analyzed, 49(24.5%) were found to be infected with ova of S. haematobium. The infection was higher among males 30(25.6%) than females 19(22.9%) although the difference was not statistically significant (χ2CAL=0.19, χ2TAB=3.84). The prevalence of Schistosoma haematobium infection among school children in relation to age showed that ages 15-19 years had the highest prevalence 13(38.2%)  and ages 5-9 had the lowest prevalence 3(8.5%). The statistical analysis also revealed that there is no significant difference (8.302) in Schistosoma haematobium infection among the four schools in the study area. The presence of many snail species especially the Bulinus spp and increased contact time with the Schistosoma haematobium infested freshwater habitat was thought to be responsible for the prevalence of the disease in the area. Finding of this study shows that urinary Schistosomiasis was found to have a low prevalence in the area studied and there is the need to intensified integrated control measures to reduce or completely eradicate the disease.

This study evaluated the larvicidal potential of the ethanolic and aqueous leaf extracts of Hyptis suaveolens Poit on the 4th larval instar of laboratory-reared Anopheles spp at varying concentrations of 0.1ml, 0.2ml, 0.3ml, 0.4ml and 0.5ml for specified periods of 24hrs, 48hrs and 72hrs. Qualitative phytochemical screening of the leaf extracts identified bioactive components like alkaloid, saponin, phenol, anthraquinone and flavonoid. The LC50 and LC90 values obtained indicate that the ethanolic leaf extracts of Hyptis suaveolens Poit had the greatest toxicity on the test organisms within 24hrs of exposure at median LC50 value of 0.485ml compared to the LC50 value of 0.625ml by its aqueous extract. The relative median potency estimates indicate that within 24 hrs, the ethanolic Hyptis suaveolens Poit was 0.161 times more potent on the test organism than aqueous Hyptis suaveolens Poit. The result of this research, therefore, underscores the efficacy of Hyptis suaveolens Poit as an eco-friendly alternative in Anopheles mosquito control. It is, therefore, recommended that quantitative phytochemical screening, application of column chromatography as well as thin layer chromatography be carried out on the extracts to isolate and purify toxic phytochemicals with larvicidal potentiality.

This study aimed to understand the effects of various energy-protein ratios of feed on nilem carp fish (Osteochilus hasselti) growth. This study was conducted from September to October 2017 at the Laboratory of Building 4, Faculty of Fisheries and Marine Sciences, Universitas Padjajaran. The average size of the test fish was ± 7 cm with an average weight of 3 grams. This was a Completely Randomized Design (CRD) experimental study consisting of 5 treatments and 3 repetition. The treatments given were 5 feed formulas based on different feed protein energy ratios, i.e. treatment A (31% protein, ratio 10), treatment B (31% protein, ratio 8), treatment C (28% protein, ratio 10), D (28% protein, ratio 8), and E (30% protein commercial feed/control). Feed, 5% of the test fish total weight, was provided 3 times a day. Parameters observed were daily growth rate, feed conversion, and survival. Data gained were analyzed using F-test, followed by Duncan Test if differences were found between treatments. Results showed that growth rate and feed conversion of all treatments were not different compared to control. The highest result was found in treatment A (31% protein, ratio 10) with a daily growth rate of 3.99% and feed conversion of 1.95%.
