Internalizing Client-Centredness in Occupational Therapy Students
Authors: Ripat Jacquie , Wener Pamela , Dobinson Kendra , Yamamoto Cynthia
Published: March 2018

Background: Pre-licensure interprofessional education prepares students for collaborative client-centred practice. However, most interprofessional educational efforts are aimed at developing the collaborative component of practice. The purpose of this article is to share the findings of a study that explored occupational therapy students’ client-centred development, in order to inform other pre-licensure educators about integrating client-centredness into uni- and interprofessional education contexts.Methods and Findings: Twenty-nine participants were recruited from each of three stages assumed to be representative of occupational therapy client-centred development in each of the two years of the educational program and during the first year of practice. Semi-structured focus groups were used to capture the participants’ experiences. The core emergent theme, internalizing client-centredness, included three main processes: identifying occupational therapy as a client-centred profession, engaging in the push and pull of client-centredness, and defining self as a client-centred practitioner.Conclusions: Educators of pre-licensure health care students should deliberately focus on client-centredness in their uni- and interprofessional education curricula; the authors offer examples of curricular opportunities focused on internalizing client-centredness. Enabling health care students to internalize client-centredness may be an important aspect of developing practitioners who are prepared to enact interprofessional collaboration for client-centred practice.

Published: March 2018

Background: Professionals from the mental health and criminal justice systems must collaborate effectively to address offender mental health, but interprofessional training is lacking. Pedagogical frameworks are required to support the development of training in this new area. To inform this framework, this article explores the readiness of professionals toward interprofessional training and demographic differences in these. It explores expectations of interprofessional training, perceived obstacles to collaborative working, interprofessional training needs, and challenges facing delivery.Methods and Findings: A concurrent mixed methods approach collected data from professionals attending a crossing boundaries interprofessional workshop. Data were collected through a combination of the Readiness for Interprofessional Learning Scale (RIPLS) questionnaire (N = 52), free text questions (N = 52), and focus groups (N = 6). Mental health and criminal justice professionals' attitude toward interprofessional learning were positive (M = 17.81; N = 43). They did not see their own service as insular (M= 4.02; N = 44) and reported strong person centredness (M = 6.07; N = 43). These findings suggest professionals are open to the introduction and implementation of future interprofessional training. There were no significant demographic differences in these attitudes.Conclusions: Professionals raised a range of generic curriculum and educator mechanisms in the development of future interprofessional training, suggesting the transfer of pedagogical frameworks from established interprofessional programs into this new arena is feasible. Context-specific factors, such as offender national policy agendas and the challenges of user involvement for mentally ill offenders, must be taken into account. Greater clarity on multi- versus interprofessional training is still required with this group of professionals.

Published: March 2018

Background: Among 12 to 17 year-olds, overweight and obesity rates have more than doubled in the past 25 years. In Quebec, the government initiatives that have been implemented to promote healthy behaviours among young people require the collaboration of many stakeholders. The objective of this study was to describe collaborative practice in secondary schools promoting healthy eating and physical activity.Methods and Findings: A descriptive multiple-case study was conducted in three Quebec secondary schools. The data collection methods consisted of a focus group, semi-structured individual interviews (21), observation of events involving collaboration among various school stakeholders (5), and document analysis (3). Qualitative analysis of intra-case and cross-case data carried out by more than one researcher helped identify emerging manifestations of collaborative practice.Conclusion: Committing to projects, accepting tasks, and consulting with colleagues are some of the actions identified in school-based activities promoting healthy lifestyles. This study sheds light on the importance of collaborative practice in the promotion of healthy lifestyles among young people in a school setting.

Published: March 2018

Background Health professions students have limited exposure to each other during education and training, yet there are many expectations for interaction in the workplace as part of functioning health care teams. We reasoned that providing students an opportunity to work together in a service learning project under faculty supervision would enhance student knowledge and appreciation of each other’s disciplines and give them a better understanding of working together. Methods and Findings Teams of students from four disciplines (medicine, nursing, dentistry, dental hygiene) worked as volunteers with a unique population of transitional homeless families to develop individualized health and wellness plans. Pre- and post-participation surveys were used to measure changes in student perceptions of working in multi-disciplinary teams, and focus groups were used to identify strengths and weaknesses of the project and future directions. Conclusions Results showed positive predispositions to working with each other which were further enhanced by collaborative, interprofessional experience. Students’ confidence in working together in multidisciplinary teams and understanding of the training and expertise of other professions increased after participation and changes were statistically significant. Interprofessional education and community service-based learning may be a powerful combination for demonstrating the value of clinical teamwork to health professions students.
Developing a Recursive Evaluation Plan of a Complex Interprofessional Healthcare Education Initiative
Authors: Parrott James Scott , Findley Patricia , Rosenthal Matthew , Rothpletz-Pugila Pamela
Published: March 2018

Background: A university interprofessional education (IPE) and interprofessional practice (IPP) initiative is a complex undertaking: incorporating multiple system levels (administration, faculty, students, patients), integrating many theoretical perspectives, and coordinating a host of individual IPE research projects. Guidance for evaluating such an IPE initiative is lacking.Methods and Findings: We describe five key challenges to evaluating the effectiveness of such an initiative, and the processes and tools we have developed to meet those challenges. We draw from recent developments in evaluation science to theoretically ground our description. Additionally, we share concrete tools we have developed in the process. By tacking between theoretical and concrete aspects of our efforts, we hope to both provide ideas for other IPE initiatives, as well as provide a basis for future research comparing cases (complex university IPE initiatives).Conclusions: While all complex IPE university initiatives are unique, we suspect that they share many common evaluation challenges. By framing these common practical challenges as common theoretical challenges, we seek to offer a description of our concrete case as well as a basis for future comparison of similar initiatives.
Do Interprofessional Educational Programmes on Eating Disorders Provide Proximal and Distal Benefits? Findings from a National Cohort Collected from 1998 to 2010
Authors: Rosenvinge Jan H , Pettersen Gunn
Published: March 2018

Background: Many programs are launched aiming to raise knowledge and competence in treating eating disorders, yet few of them have been evaluated. Methods and Findings: Using a pre-post and one-year repeated measures design we evaluated a 17-month interprofessional education program (Body and Self-Esteem) comprising a national cohort of participants (n = 845) enrolled from 1998 to 2010. The purpose of the program is to raise health professionals’ 1) knowledge, 2) confidence, 3) clinical competence, and 4) to promote an understanding of how patient care can be organized in an interdisciplinary fashion. The program format consists of five to six one- to three-day seminars with plenary lectures, and four to six closed network groups. The detected changes in all four outcomes were unrelated to program-irrelevant covariates. Program satisfaction was high, and on par with initial expectations. Conclusions: Limited by the fact that a randomized controlled design was impossible to use, a reasonable conclusion is that the program may have provided both immediate and longer-term benefits.

Authors: Davis Deborah Lee , Hercelinskyj Gylo , Jackson Lynette M.
Published: March 2018

Background: Contemporary health services increasingly call for teamwork and interprofessional collaboration, though undergraduate curricula provide few opportunities for students to develop the necessary skills. This article presents the results of an innovative pilot project focusing on providing an interprofessional clinical learning experience for students using the virtual world of Second Life.Methods and Findings: A pilot project was implemented and tested on a small group of students studying at two institutions in four healthcare programs. Qualitative descriptive methods were employed to analyze semi-structured interview transcripts. The evaluation revealed that participants were easily able to manage the technologies associated with Second Life and the learning and teaching strategies were engaging and useful. While the project provided students with an opportunity to learn more about the role of other health professionals and their contribution to patient care, it will require some development before it achieves in full the aim to promote interprofessional collaboration. Conclusions: Simulation in virtual worlds such as Second Life offers promise in the area of interprofessional education.
A Cross Comparative Study to Examine Beliefs and Attitudes regarding Food and Eating between Food and Nutrition and Social Work Students
Authors: McMillan Colleen , Madill Janet
Published: March 2018

Background: Little is known regarding attitudes and beliefs toward eating disorders by students interested in working with this population. This study aims to understand similarities and differences between food and nutrition and social work students regarding their attitudes and beliefs toward food and eating, and how these findings may inform curriculum development prior to graduation as well as practice in the field.Methods and Findings: Using a mixed-method approach, 14 social work (SW) and26 food and nutrition (FN) students completed the Eating Disorders Attitudes Questionnaire (EAT-26) and participated in focus groups. After viewing 33 photographs of 11 different foods displayed as small, normal, and large portions according to Canada’s Food Guide, students categorized portions followed by their rationale. Different symptoms of disordered eating emerged; choices by FN students were informed by clinical knowledge and internal tension, whereas choices by SW students were based on external influences including industry, family, and cultural expectations. Language was noticeably different; FN students used clinical language creating distance between themselves and the photos, versus SW students who spoke from a personal and affective standpoint.Conclusions: Understanding attitudes and beliefs concerning food and eating by students planning to work with eating disorder clients raises questions of possible professional competencies and curriculum development prior to entering this practice area.

Published: March 2018

Hyperadrenocorticism (HAC), also known as Cushing's Syndrome, is a disease manifested by a series of clinical changes and multisystem abnormalities resulting from increased chronic exposure to glucocorticoids secreted by the adrenal glands or excessive administration of this hormone. Two different categories of medications are currently used in the treatment of HAC: inhibitors of steroidogenesis and modulators of ACTH secretion. Among the drugs inhibiting steroidogenesis the most indicated in practice by veterinarians is trilostane. However, due to its high cost, there is a need to study drugs that may have a systemic action in the control of clinical and hematological alterations in CAH. Thus, the present study aims to evaluate the use of ketoconazole as the drug of choice in the treatment and control of clinical and hematological changes of canine hyperadrenocorticism. At 8-year-old Poodle dog with diagnosis of hyperadrenocorticism was attended at the Metropolitan Veterinary Polytechnic of Caucaia - HVM. The guardian reported that the dog was 4 months without using Trilostan because it did not have financial conditions to maintain the treatment, which significantly worsened the clinical signs previously presented: polydipsia, polyuria, polyphagia, hyperpigmented skin with lesions, symmetrical alopecia, telangiectasia, pendular abdomen, muscle weakness in the pelvic limbs. Dyspnea was visually detected and cardiac auscultation detected tachycardia. Laboratory, ultrasonographic and cardiac evaluation (electrocardiogram and echocardiogram) were requested. Due to changes in the results of the tests, the veterinarian suggested the use of ketoconazole at the initial dose of 5mg / kg / VO / BID for 7 days and silymarin 180mg / VO / SID.com for purpose of controlling the patient's clinical symptoms and the observed changes in the examinations carried out. After this period, there was a significant improvement in the hematological and biochemical alterations of the patient, however the animal clinically presented worsening, presenting frequent vomiting and inappetence. In view of the above, it can be concluded that the use of ketoconazole in the treatment of patients with canine CAH should be used only as an adjuvant treatment, since despite the significant improvement of the hematological and biochemical changes related to the endocrine disorder does not improve clinical symptoms.
Uso de medicamentos homeopáticos para o tratamento da mastite bovina: Revisão
Authors: Jesus Renan , Coutinho César Alberto
Published: March 2018

. Mastitis presents as the most important disease in milk cows, due to the damages caused by loss of productivity and milk discharge according to some treatments, such as antimicrobials. Faced with the problem of antibiotics due to poor application or bacterial resistance, an alternative for the control of mastitis is the use of homeopathy. The aim of the present study is to inform what has already been researched about the use of homeopathic medicines for the treatment of mastitis. Homeopathic therapy fits within the precepts of organic farming, being a suitable method for this purpose. The remedies used for the treatment of the disease are from the most diverse origins, plants, minerals, animals and of great representatively, of isolates or bacterial compounds, of microorganisms that are the cause of mastitis. The ease of administration of homeopathic medicines presents a great advantage, since in the most common form of use, it can be added in drinking water or mixed in the feed avoiding stress on the part of the animal. The results in mastitis due to the application of homeopathy can be visualized in the variation of the somatic cell count, reactions in the CMT (California Mastitis Test), absence of isolation of milk microorganisms and decrease in the percentage of cases of clinical and subclinical mastitis. Although the homeopathic treatment proves to be a great alternative for the control and treatment of mastitis, the results are quite variable due to the different methodologies used and the large number of different homeopathic medicines used.

Published: March 2018

La-doped RuO2?TiO2/Ti coating (TRL) and RuO2?TiO2/Ti coating (TR) were prepared by the sol?gel method and thermal treatment. The products were characterized by X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM). The electrochemical properties were investigated by cyclic voltammetry and polarization measurements in O2 and Cl2 evolution in H2SO4 and NaCl solution. The XRD analysis showed that in both TRL and TR, the particles of the synthesized coatings were of low crystallinity, and that they were mainly formed of two phases, rutile TiO2 and RuO2. SEM confirmed that the surface of TRL and TR coatings had a cracked mud appearance consisting of blocks separated by cracks. The morphology of the TRL coating shows irregular crack blocks, which increased the specific area greatly and provides more active sites. Polarization measurements indicate that the onset potential of chlorine evolution reaction for TRL coating was 1.08 VSCE, which is lower than the value of 1.12 VSCE registered for the TR coating. The onset potentials for oxygen evolution for the two coatings were similar. Cyclic voltammetry shows an improvement of the electrochemical capacity for the La-doped coatings.
Victimization as a strategy of the artistic representation of the past: The case of the NATO bombing of the FRY
Authors: Mihaljinac Nina
Published: March 2018

Using the research that mapped around 160 visual art works on the topic of
NATO bombing of the FRY, the paper deals with the problem of incorporating
various narratives of memory and artistic representations of collective
traumas into the public memory discourse in Serbia (creation of sacrificial
culture, rival memories, forgetting). The aim of the paper is to point out
the possible methods of developing a holistic, inclusive and critical culture
of remembrance that would lead to the treatment of collective traumas, and to
underline the importance of showing public respect for all narratives of
memory, and thus also narratives of victimization, which can often be
politically abused. Therefore, the paper offers a new typology of
representation of collective traumas, based on psychological analyses of
types of traumatic reactions. The typology aims to achieve 1) equal
appreciation of sufferings and all narratives of remembering, 2) critique of
political misuses of narratives of trauma and reductionism. In order to
overcome social tensions arising from the construction of the official
sacrificial- patriotic narratives, it is necessary to break the binary
constructed identities of ?good? and ?bad? ones, and to discover other
narratives of the past, such as activist artistic memories.
The media: Minimizing re-victimisation through duty of care for victims and responsible journalism
Authors: Simons Sarah
Published: March 2018

This article discusses how professionally unethical practices by journalists
during collection and dissemination of crime incident information in Africa,
could exacerbate harm to victims of terrorist attacks. The views expressed
the outcome of a desk-based study on crime reporting in Africa. Writing
through the lens of ?vulnerability? from a non-western context, this article
highlights double standards applied by some foreign and international press,
who observe stipulated ethical reporting standards ?at home? thereby
avoiding further harm to crime victims, while disregarding these guidelines,
or applying them selectively ?abroad?. Reports on the Westgate Mall
21/9/2017 terrorist attack in Nairobi are used to illustrate the potential
of ?jigsaw puzzle effect? in leading to additional victimisation by making
victims identifiable, compromising their safety and psychological well-being
while portraying disrespect for human dignity. The author advocates
responsible journalism as a reflection of the duty of care for victims?
welfare and encourages further discussion on ethical considerations in
professional crime reporting.
Image-Guided Surgery Using Invisible Near-Infrared Light: Fundamentals of Clinical Translation
Authors: Gioux Sylvain , Choi Hak Soo , Frangioni John V.
Published: March 2018

The field of biomedical optics has matured rapidly over the last decade and is poised to make a significant impact on patient care. In particular, wide-field (typically > 5 cm), planar, near-infrared (NIR) fluorescence imaging has the potential to revolutionize human surgery by providing real-time image guidance to surgeons for tissue that needs to be resected, such as tumors, and tissue that needs to be avoided, such as blood vessels and nerves. However, to become a clinical reality, optimized imaging systems and NIR fluorescent contrast agents will be needed. In this review, we introduce the principles of NIR fluorescence imaging, analyze existing NIR fluorescence imaging systems, and discuss the key parameters that guide contrast agent development. We also introduce the complexities surrounding clinical translation using our experience with the Fluorescence-Assisted Resection and Exploration (FLARE™) imaging system as an example. Finally, we introduce state-of-the-art optical imaging techniques that might someday improve image-guided surgery even further.

Given that overexpression of the epidermal growth factor receptor (EGFR) is found in many types of human epithelial cancers, noninvasive molecular imaging of this receptor is of great interest. A number of studies have employed monoclonal antibodies as probes; however, their characteristic long half-life in the bloodstream has encouraged the development of smaller probes. In this study, an anti-EGFR nanobody-based probe was developed and tested in comparison with cetuximab for application in optical molecular imaging. To this aim, the anti-EGFR nanobody 7D12 and cetuximab were conjugated to the near-infrared fluorophore IRDye800CW. 7D12-IR allowed the visualization of tumors as early as 30 minutes postinjection, whereas with cetuximab-IR, no signal above background was observed at the tumor site. Quantification of the IR-conjugated proteins in the tumors revealed ≈ 17% of injected dose per gram 2 hours after injection of 7D12-IR, which was significantly higher than the tumor uptake obtained 24 hours after injection of cetuximab-IR. This difference is associated with the superior penetration and distribution of 7D12-IR within the tumor. These results demonstrate that this anti-EGFR nanobody conjugated to the NIR fluorophore has excellent properties for rapid preclinical optical imaging, which holds promise for its future use as a complementary diagnostic tool in humans.

Published: March 2018

The aim of this study was to determine whether the severity of contact hypersensitivity reactions (CHSRs) can be observed by noninvasive in vivo optical imaging of matrix metalloproteinase (MMP) activity and whether this is an appropriate tool for monitoring an antiinflammatory effect. Acute and chronic CHSRs were elicited by application of a 1% trinitrochlorobenzene (TNCB) solution for up to five times on the right ear of TNCB-sensitized mice. N-Acetylcysteine (NAC)-treated and sham-treated mice were monitored by measuring ear swelling and optical imaging of MMP activity. In addition, we performed hematoxylin-eosin staining and CD31 immunohistochemistry for histopathologic analysis of the antiinflammatory effects of NAC. The ear thickness and the MMP activity increased in line with the increasing severity of the CHSR. MMP activity was enhanced 2.5- to 2.7-fold during acute CHSR and 3.1- to 4.1-fold during chronic CHSR. NAC suppressed ear swelling and MMP signal intensity in mice with acute and chronic CHSR. During chronic CHSR, the vessel density was significantly reduced in ear sections derived from NAC-treated compared to sham-treated mice. In vivo optical imaging of MMP activity measures acute and chronic CHSR and is useful to monitor antiinflammatory effects.
In Vivo Quantification of 5-HT2A Brain Receptors in Mdr1a KO Rats with 123I-R91150 Single-Photon Emission Computed Tomography
Authors: Dumas Noé , Moulin-Sallanon Marcelle , Fender Pascal , Tournier Benjamin B. , Ginovart Nathalie , Charnay Yves , Millet Philippe
Published: March 2018

Our goal was to identify suitable image quantification methods to image 5-hydroxytryptamine2A (5-HT2A) receptors in vivo in Mdr1a knockout (KO) rats (i.e., P-glycoprotein KO) using 123I-R91150 single-photon emission computed tomography (SPECT). The 123I-R91150 binding parameters estimated with different reference tissue models (simplified reference tissue model [SRTM], Logan reference tissue model, and tissue ratio [TR] method) were compared to the estimates obtained with a comprehensive three-tissue/seven-parameter (3T/7k)-based model. The SRTM and Logan reference tissue model estimates of 5-HT2A receptor (5-HT2AR) nondisplaceable binding potential (BPND) correlated well with the absolute receptor density measured with the 3T/7k gold standard ( r > .89). Quantification of 5-HT2AR using the Logan reference tissue model required at least 90 minutes of scanning, whereas the SRTM required at least 110 minutes. The TR method estimates were also highly correlated to the 5-HT2AR density ( r > .91) and only required a single 20-minute scan between 100 and 120 minutes postinjection. However, a systematic overestimation of the BPND values was observed. The Logan reference tissue method is more convenient than the SRTM for the quantification of 5-HT2AR in Mdr1a KO rats using 123I-R91150 SPECT. The TR method is an interesting and simple alternative, despite its bias, as it still provides a valid index of 5-HT2AR density.

Published: March 2018

Objectives:

The purpose of this prospective, double-blind, randomized clinical trial was to compare the clinical efficiency of nickel-titanium (NiTi) and niobium-titanium-tantalum-zirconium (TiNbTaZr) archwires during initial orthodontic alignment.

Materials and Methods:

All subjects (ages between 12 and 20 years) underwent nonextraction treatment using 0.022-inch brackets. All patients were randomized into two groups for initial alignment with 0.016-inch NiTi archwires (n = 14), or with 0.016-inch TiNbTaZr archwires (n = 14). Digital scans were taken during the course of treatment and were used to compare the improvement in Little's Irregularity Index and the changes in intercanine and intermolar widths.

Results:

There was approximately a 27% reduction in crowding during the first month with the use of 0.016-inch TiNbTaZr (Gummetal) wire, and an additional 25% decrease in crowding was observed during the next month. There was no significant difference between the two treatment groups in the decrease in irregularity over time (P = .29). There was no significant difference between the two groups in the changes in intercanine and intermolar width (P = .80).

Conclusions:

It can be concluded that Gummetal wires and conventional NiTi wires possess a similar ability to align teeth, and Gummetal wires have additional advantages over conventional NiTi, such as formability and use in patients with nickel allergy.
Fatigue Failure Load of Restored Premolars: Effect of Etching the Intaglio Surface of Ceramic Inlays With Hydrofluoric Acid at Different Concentrations
Authors: Missau T , Venturini AB , Pereira GKR , Prochnow C , Valandro LF , Rippe MP
Published: March 2018

The aim of this study was to evaluate the effect of etching, with different hydrofluoric acid concentrations at the intaglio surface of feldspathic ceramic inlays, on the fatigue failure load of restored premolars. A total of 60 upper premolars were embedded in plastic cylinders with acrylic resin (up to 3 mm below the cement-enamel junction) and prepared using a device specially designed for that purpose. Teeth were randomly assigned to three groups (n=20): HF1, HF5, and HF10 (etching with hydrofluoric acid for 60 seconds at concentrations of 1%, 5%, and 10%, respectively). Preparations were scanned and restorations were milled by a computer-aided design / computer-aided manufacturing system. The inner surfaces of the inlays were etched and received an application of a silane coupling agent; the dentin and enamel were treated appropriately for the luting system (RelyX ARC, 3M-ESPE). The restorations were cemented and the fatigue failure load (in N) was determined using the staircase method (10 Hz; 105 cycles in each step). The initial load (585.5 N) was applied on the slopes of the cusps (labial and palatal/lingual, simultaneously) through a cylinder attached to the test machine (Instron ElectroPuls E3000). The tested samples were analyzed under a stereomicroscope for failure analysis. Fatigue data were analyzed by one-way analysis of variance. There was no statistical difference among the fatigue failure loads (in N): HF1 (448.5±79.1), HF5 (360.7±55.4), and HF10 (409.5±121.1). Regarding the fracture mode, there was a predominance of interfacial fracture (50%), followed by cusp fracture (34.6%). It may be concluded that the etching with hydrofluoric acid at the tested concentrations (1%, 5%, and 10%) does not influence the fatigue failure load of feldspathic ceramic inlays cemented on premolars.
ON THE COMPARATIVE ANALYSIS OF THE COOLEY-TUKEY AND BLUESTEIN NUMERICAL FAST FOURIER TRANSFORMS ALGORITHMS FOR DIGITAL SIGNAL PROCESSING
Authors: Amannah Constance Izuchukwu
Published: March 2018

ABSTRACT  This study was designed to compare the computing efficiency of C-TNADSP and the BNADSP to ascertain a more efficient numerical algorithm necessary for the processing of digital signals. The faster numerical algorithm established in this study is abbreviated with RCC-TNADSP (Resultant Compared C-TBNADSP). The methodology adopted in this work was comparative analysis development design. The major technologies used in this work are the C-TNADSP and BNADSP, and the c++. The c++ served as a signal processing language simulator (SPLS). The execution times of the Cooley-Tukey and the Bluestein algorithms were 3.44 seconds and 3.50 seconds respectively.  On comparing the speeds of the fast Cooley–Tukey and the fast Bluestein algorithms we observed that the Cooley-Tukey algorithm has 0.06 seconds speed improvement over the Bluestein algorithm. In line with this outcome, we concluded that the Cooley-Tukey algorithm (C-TNADSP) is faster than the Bluestein algorithm (BNADSP). In the same vein the Cooley-Tukey algorithm (C-TNADSP) is therefore the fastest DSP algorithm. This is however faster than the spectrum of FFT algorithms of O(nlogn) computing speed. The algorithms were tested on input block width 1000 units, and above, and can be implemented on input size of 100 000, and 1000 000 000 without the challenge of storage overflow. The input samples tested in this work was the discretized pulse wave form with undulating shape out of which the binary equivalents were extracted. Other forms of signals may also be tested in this fast algorithm provided they are interpreted in the digital wave type. KEYWORDS:  Algorithm, FFT, Cooley-Tukey, Bluestein, Comparison, Analysis, FFT
Improving Security of RFID Authentication Protocol Based on Fast Fourier Transform and Deoxyribonucleic Acid
Authors: Grewal Vibhu
Published: March 2018

RFID based applications used for many purposes like tagging and tracking for tag and reader in IoT deployment. This is because of its powerful features compared with similar techniques such as barcodes. In contrast, various attacks and security threats cause to RFID system. The aim of this paper is to use a heterogeneous ensemble of Fast Fourier Transform algorithm and Deoxyribonucleic acid (DNA) sequence operations. This is different from existing ECC work in the sense that we are proposing to combine state-of-the-art encryption methods by ensemble techniques instead of focusing on single technique. Our proposed protocol is highly secure and its strength is based on FFT and DNA encoding rules. When compared with ECC technique we validate and demonstrate our approach experimentally and it leads to significant performance gains.

Al margen de la “mitologización”, cuyo fin es incluir las historias de esta larga secuencia en la trama precedente constituyendo una historia universal “mitologizada”, hay en la llamada “Eneida ovidiana” marcas textuales que sirven para mantener vigente el valor de la figura y la historia de Eneas en conformidad con la significación romana del héroe y, en especial, con la apoteosis, que da fin a la secuencia. Tales marcas constituyen lo que hemos dado en llamar el plano de la “lectura”.  En este trabajo indagamos, a propósito de la “Eneida ovidiana”, las alusiones al Aeneas Romanus, construido en particular por la obra de Virgilio y al que Ovidio sigue en cuanto al significado general, más allá de ocasionales referencias a tradiciones previas no incluidas por Virgilio. Entendemos por Aeneas Romanus el que, dada la índole canónica de su Eneida, Virgilio termina de convertir en patrimonio de la cultura romana, sancionando a la vez su carácter de mito originario de una familia. Entre esas alusiones es central la designación Cythereius heros en Ringkomposition, que remeda Aen., I, 257-258 y asegura el valor virgiliano de la secuencia en el plano de la “lectura”.

Telah dilakukan penelitian analisis waktu pemupukan pada tanaman sawi hijau (Brassica rapa var. parachinensis)dengan teknik perunut radioaktif. Untuk menuju sistem pertanian berkelanjutan perlu adanya perbaikan pertanian(intensifikasi) selama beberapa tahun yang lalu masih signifikan, karena ketersediaan sumber daya alam danteknologi pertanian cukup memadai dan berimbang dengan ketersediaan lahan dan peningkatan jumlah penduduk.Keadaan ini sulit untuk dipertahankan dimasa yang akan datang, kecuali ada pendekatan baru yang menawarkan ide dan teknik untuk meningkatkan produktifitas pertanian. Efesiensi pemupukan tanaman dengan teknik perunut (tracer) radioisotop adalah salah satu potensi menujusistem pertanian berkelanjutan. Teknik perunut dapat digunakan antara lain untuk mempelajari hubungan antaratanah dan tanaman, menentukan kondisi optimal dalam penggunaan pupuk (waktu pemupukan, pola perakaranaktif tanaman, jenis dan takaran pupuk), mempelajari proses dekomposisi dan mineralisasi bahan organik, sertamempelajari proses fotosintesis tanaman,baik dengan metoda langsung maupun tidak langsung.Waktu pemupukanyang lebih tepat dapat ditentukan dengan teknik perunut tersebut, sehingga optimalisasi pemupukan dapat dicapai,tanpa pemborosan yang tidak berguna.Dari penelitian dengan menggunakan radioisotop P, ternyata waktupemupukan pada tanaman sawi hijau (Brassica rapa var. parachinensis) yang paling signifikan adalah padapukul 9.00 pagi. Waktu siang hari mulai pukul 11.00 sampai pukul 15.00 adalah waktu pemupukan yang sangatburuk. Sedangkan waktu sore hari yaitu pukul 15.00 sampai 17.00 menunjukkan waktu pemupukan yang semakinbaik namun tidak signifikan.32

The development of free-range chicken farm is constrained by expensive food prices. On the other hand,feses of cattle had potential use as a source of feed. This study was conducted to determine the response ofcow feses and probiotics administration in the diet of laying range chicken. The study was conducted over 6months using 240 free-range chickens aged 8 months. Research was arranged in a completely randomized designwith 8 treatments and 5 replications. The treatment given were ration in accordance with the farmers formulacomprising: concentrate: 25%, corn 40% and rice bran 35% (P0) and ration as P0, with the substitution of ricebran with fermented cow feses each treatment with level 10 % (P1), 15% (P2) and 20% (P3) and ration as atP0, P1, P2 and P3 that received additional probiotic (Bio L) 1 cc / L of drinking water (P4, P5, P6 and P7). Theparameters were observed are: egg production (hen day), egg weight, feed intake, FCR (Feed Conversion Ratio)mortality and physical composition of eggs. The results showed that the diet which containing fermented cowfeses 20% did not decreased egg production and feed efficiency. The combination of fermented cow feses at thelevel of 20% with a probiotic (Bio L) 1 cc / L of drinking water showed that egg production  increased althoughit is not significant and reduce the number of FCR (Feed Conversion Ratio). In conclusion the use of fermentedcow feses up to the level of 20% in the diet both with and without the administration of probiotics, has no effecton physical composition of eggs.

Calliandra calothyrsus leaves contain 17-28% protein thus potential as a protein source in animal diet. However, it also contain a high antinutrition of condensed tannins (>10%). The addition of protease enzymes (bromelain) in the diet containing tannins is expected to overcome the negative effects of tannins. Bromelain can be obtained from the pineapple plant (Ananas comosus) including the peel. This study was a feeding experiment on weaned male and female rats during the growth period. This study used a completely randomized design of 4x4 factorial design. The main factor was Calliandra leaf meal substitution levels of 0; 10; 17.5 and 25% in the diet. The sub factor was pineapple peel additive levels of 0; 4.35; 8.70 and 13.05 g/rat/day. Weaned rats were divided into 16 groups and they were fed for two months during growth period. The study showed that there was no interaction between calliandra leaves and pineapple peels on the rat liver activity including the blood levels of SGOT and SGPT levels. SGPT and SGOT levels were not affected by all levels of pineapple peels in the diets. All calliandra levels did not affect the level of SGOT, but 17.5 and 25% calliandra in the diets increased SGPT level.

Food insecurity in Sub - Saharan Africa (SSA) is on the rise due to soil fertility depletion and in Kenya, Nitrogen (N) is one of the widely deficient nutrients. Biological nitrogen fixation (BNF) can replenish N into the soil system. A study was carried out in acid soils at Koyonzo and Ligala sites of western Kenya to determine the effectiveness of different inoculants after agricultural lime application in enhancing BNF and yields of groundnuts (Arachis hypogea L.) and maize (Zea mays L.) intercrop. Red Valencia groundnut variety was intercropped with Hybrid 513D maize variety. A6w, W1w and V2w indigenous rhizobia strains were tested alongside a commercial rhizobia strain called biofix. Nitrogen treatment was included as a positive control. The results showed that inoculation significantly increased nodule number and weight per plant. There were significant differences among indigenous rhizobia in fixing N. Rhizobia inoculation accounted for 58.91% and 78.95% increase in the amount of N fixed above the control at Koyonzo and Ligala respectively. The strain that fixed the highest amount of N was A6w followed by V2w and W1w at both sites under the dolomitic soil amendment with the values of 14.67, 9.56, 3.53 and 11.37, 8.20 and 1.50 kg N ha-1, respectively at Koyonzo and Ligala sites. Rhizobia inoculation accounted for 80.96% and 47.09% maize yield increase at Koyonzo and Ligala respectively. The best inoculant A6w, gave maize yields of 3.76 and 2.78 t ha-1 at Koyonzo and Ligala, respectively. In conclusion soil amendment with dolomitic lime and inoculating groundnuts with rhizobia strain A6w resulted in increased groundnut and maize yields. This practice can, therefore, be adopted by farmers in western Kenya to improve the productivity of the groundnut maize intercropping systems.

Learning process determines the improvement of students’ learning achievements. Selection of an appropriate learning experience is the task of the teacher as a facilitator in charge of providing a supportive learning environment for the students. This study aims to determine the perception of teachers after implementing learning using Problem Based Learning model. The subject of this research is the Math teachers at State Senior High School 1 Wuryantoro, Wonogiri Regency, Academic Year 2017/2018. Data are collected using interviews to find out teachers' perceptions of the implementation of Problem Based Learning model. The result shows that the Probem Based Learning model make it easier for teachers to learn in the classroom because students are more interested and active, but teachers are often constrained in constructing contextual problems that can connect with the intended concept. Limited time allocation is also a constraint of implementing learning using Problem Based Learning.
