DINAMIKA PSIKOLOGIS KORBAN KEKERASAN SEKSUAL PADA ANAK LAKI-LAKI (STUDI KASUS DI KARAWANG)
Authors: Cempaka Putrie Dimala
Published: November 2019

This study aims to determine how the psychological dynamics of children victims of sexual violence. This research was conducted on two boys of middle age and late childhood who had experienced sexual violence in Karawang. Considering the many and breadth of these elements, in this study using a sampling technique using purposive sampling technique. The results of this study indicate that the psychological dynamics of victims of sexual violence have the same pattern. Characteristics of victims who are quiet and resigned, as well as families who do not provide supervision and protection of the subjects. Both of them influenced each other towards the occurrence of acts of sexual violence which made him gain traumatic experiences. Traumatic experiences and negative social conditions influence the emergence of social anxiety which makes it develop a sense of inferiority. And this anxiety is covered by withdrawal from the environment. While the second subject, the repeated sexual assault was tried to be suppressed and forgotten, but the condition that arose was a strong desire to fulfill the pleasure of sexual violence. Keywords: The dynamics of Psychology, Sexual Assualt, Boys.

 

Penelitian ini bertujuan untuk mengetahui bagaimana dinamika psikologis anak-anak korban kekerasan seksual. Penelitian ini dilakukan pada dua orang anak laki-laki dengan rentang usia masa kanak-kanak pertengahan dan akhir yang pernah mengalami peristiwa kekerasan seksual di Karawang. Mengingat banyak dan luasnya unsur tersebut, maka dalam penelitian ini menggunakan teknik penentuan sampel dengan menggunakan teknik purposive sampling. Hasil penelitian ini menunjukkan bahwa dinamika psikologis korban mendapat kekerasan seksual memiliki pola yang sama. Karateristik korban yang pendiam dan pasrah, serta keluarga yang kurang memberikan pengawasan dan perlindungan terhadap subyek. Keduanya saling mempengaruhi terhadap terjadinya tindakan kekerasan seksual membuatnya mendapatkan pengalaman traumatis. Pengalaman traumatis dan kondisi sosial yang negatif berpengaruh pada munculnya kecemasan sosial yang membuatnya mengembangkan rasa rendah diri. Dan kecemasanya ini ditutupi dengan penarikan diri dari lingkungan. Sementara subjek kedua, kekerasan seksual yang berkali-kali diterimanya ini berusaha ditekan dan dilupakan akan tetapi kondisi yang muncul adalah keinginan yang kuat untuk memenuhi kembali kenikmatan dari kekerasan seksual itu.

KONSEP DIRI PADA PEREMPUAN KORBAN KEKERASAN SEKSUAL DI KARAWANG
Authors: Nuram Mubina
Published: November 2019

The purpose of this study is to describe the self-concept of victims of sexual violence. The subjects in this study consisted of two female respondents who had experienced sexual violence. This study uses phenomenological qualitative methods so that data collection is carried out intensively, deeply, and comprehensively. Data collection is done by interview and observation techniques. To ensure the validity of the data, the researcher triangulates the data. Data analysis activity begins with data collection, personalization, and creating units of meaning to get a textural description. The results of this study indicate that all research respondents from the beginning have negative self-concepts so that they are easy to agree on when others ask or force them to have sexual relations. The impact of sexual violence continued to influence the development of both respondents' self-concepts. One respondent showed an increasingly negative self-concept that is assessing herself as a naughty woman and eventually engaging in risky sexual relations, drug use and alcohol. Other respondents, although trying to have a better life, still let the environment judge themselves negatively. These conditions affect the self-concept which still leads to negative self-concept characteristics.

Published: November 2019

Um estudo foi realizado com o objetivo de avaliar as características seminais do cará Geophagus brasiliensis mantido em cativeiro com e sem indução hormonal. Para tanto, foram utilizados 26 machos distribuídos entre os seguintes tratamentos: nove machos sem indução hormonal; nove machos com indução hormonal de extrato de hipófise de carpa (HC) e oito machos com indução hormonal por gonadotropina coriônica humana (HCG). Os parâmetros avaliados para a caracterização seminal nos diferentes tratamentos foram volume seminal, cor do sêmen, motilidade espermática, vigor espermático, tempo de latência, concentração espermática e viabilidade espermática. Os dados foram submetidos à análise de variância com 95% de confiança. A coloração do sêmen foi classificada como branco leitoso. Os valores médios para a motilidade, vigor espermático e concentrações dos espermatozoides foram: 94,44%, 78,75% e 63,88%; 4,44, 4,00 e 3,55; 5,10, 5,00 e 5,72 x 109  mL-1, para os tratamentos sem indução, HCG e HC, respectivamente. O tempo de latência espermático variou de 143,4 a 988,2 segundos e a viabilidade espermática foi de 100% para todos os tratamentos. A análise de variância não apresentou diferença significativa entre os efeitos dos diferentes tratamentos sobre nenhum dos parâmetros avaliados. Embora os resultados tenham demonstrado não ser necessária a indução artificial de machos durante o período reprodutivo, outros protocolos de reprodução artificial devem ser testados para G. brasiliensis vislumbrando o uso da espécie de forma comercial na aquicultura.

Published: November 2019

Considerando a importância farmacológica de orégano (Origanum vulgare L.) e hortelã (Mentha piperita L.), o desenvolvimento de formas de propagação e cultivo in vitro poderá contribuir para a inserção dessas espécies em sistemas de produção sustentáveis, com características genéticas preservadas. O objetivo deste trabalho foi verificar o tipo explante mais promissor para o estabelecimento in vitro de orégano (Origanum vulgare L.) e hortelã (Mentha piperita L.). Os tratamentos adotados foram: a introdução de três tipos de explantes: segmentos nodais, segmentos foliares e sementes. Cada explante foi introduzido, individualmente, em tubo de ensaio, contendo 15mL do meio de cultivo DSD1. Avaliou-se, aos sete, 14 e 21 dias após a introdução in vitro, o percentual de resposta positiva de introdução: brotação, para segmentos nodais; sobrevivência, para folhas e germinação, para sementes; contaminação (fungos e bactérias), oxidação e número de brotos por explante. O delineamento experimental utilizado foi o completamente casualizado, com três repetições, compostas por 10 tubos de ensaio, em cada tratamento. As médias observadas foram diferenciadas pelo teste de Tukey 5%. Os resultados indicam que para o estabelecimento in vitro de orégano somente os segmentos nodais apresentaram regeneração de plantas. Enquanto que para hortelã, os explantes segmentos nodais e sementes apresentaram resultado positivo. Mais estudos devem ser realizados à fim de reduzir as contaminações por fungos e bactérias.
Catch me if you can – Auf der Spur der Cercospora-Sporen
Authors: Imbusch Frederike , Erven Tobias , Varrelmann Mark
Published: November 2019

Cercospora beticola ist der Erreger der bedeutendsten Blattfleckenkrankheit an Zuckerrüben. Die Ausbreitung der Krankheit findet durch Konidiosporen statt, die hauptsächlich durch Wind und Spritzwasser verbreitet werden. Vor dem Hintergrund der sich verschärfenden Problematik verringerter Wirksamkeiten einiger fungizider Wirkstoffklassen gegen die Cercospora-Blattflecken bedarf es zukünftig einer nachhaltigeren Behandlungsstrategie. Hierfür sind Kenntnisse über die Ausbreitungsdynamik des Erregers grund-legend. Bisherige Studien fokussierten sich auf die Ausbreitung des Befalls im Bestand oder den Zusammenhang von Sporenflug und Befallsentwicklung. Es ist unklar, wie sich die C. beticola-Sporen und aufgrund dessen der Befall von einer Inokulumquelle ausbreiten. Ein schneller Nachweis von C. beticola-Sporen in der Luft könnte zukünftig eine zeitspezifische und gezieltere Bekämpfung der Blattflecken ermöglichen. Zur Detektion und Quantifizierung von C. beticola-Sporen aus Rotarod-Sporenfallen wurden eine DNA-Extraktion und TaqMan-qPCR entwickelt. Jeweils ein Feldversuch wurde in den Jahren 2016 und 2017 von Juni bzw. Juli bis August bei Göttingen durchgeführt. Der Sporenflug von C. beticola und der Krankheitsverlauf wurden innerhalb einer inokulierten Fläche sowie in verschiedenen Distanzen zu dieser erfasst. In den Versuchsflächen erfolgten keine Fungizidapplikationen. Mit der entwickelten Nachweis- methode konnten C. beticola-Sporen in Sporenfallen-Proben erfolgreich detektiert werden. Die quantifizierten C. beticola-DNA-Mengen konnten als Maß für die Intensität des Sporenflugs genutzt werden. Bezüglich der zeitlichen Entwicklung und räumlichen Ausbreitung des Sporenflugs und der Befallsstärke wurde im Jahr 2017 beobachtet, dass sich mit einer zunehmenden Distanz zu einer Inokulumquelle die Zunahmen der Sporenflugintensität und der Befallsstärke zeitlich verzögerten. Die Ergebnisse aus 2016 wiesen einen ähnlichen Trend auf. Dies impliziert, dass die Ausbreitung der Krankheit über kurze Distanzen und auf Feldebene stattfindet. Ferner schien insbesondere der sekundäre Sporenflug, ausgehend von Blattflecken an den Pflanzen, für eine intensive Befallsentwicklung verantwortlich gewesen zu sein. Die Ergebnisse dieser Arbeit zeigen erstmalig eine Ausbreitungsdynamik der Sporen und Blattflecken von einer Inokulumquelle für die Region Mitteleuropa. Hieran wird das Potenzial der Nutzung des Sporenflugs für weitere Anwendungen wie Befallsmonitoring oder Behandlungsentscheidungen deutlich.
Inhibition of Long Noncoding RNA CRNDE Increases Chemosensitivity of Medulloblastoma Cells by Targeting miR-29c-3p
Authors: Sun Xiao-hui , Fan Wen-jie , An Zong-jian , Sun Yong
Published: November 2019

Long noncoding RNA CRNDE (CRNDE) recently emerged as a carcinogenic promoter in various cancers including medulloblastoma. However, the functions and molecular mechanisms of CRNDE to the acquired drug resistance of medulloblastoma are still unclear. The transcript levels of CRNDE were
examined in four medulloblastoma cell lines exposed to cisplatin treatment, and IC50 values were calculated. Effects of CRNDE knockdown or miR-29c-3p overexpression on cell viability, colony formation, apoptosis, migration, and invasion were assessed using the CCK-8, colony formation
assay, flow cytometry, and Transwell assays, respectively. RNA pulldown and RNA-binding protein immunoprecipitation (RIP) were performed to confirm the molecular interactions between CRNDE and miR-29c-3p involved in medulloblastoma cells. The in vivo role of CRNDE knockdown or miR-29c-3p overexpression
on tumor growth and apoptosis was evaluated in a xenograft mouse model of human medulloblastoma. The transcript levels of lncRNA CRNDE were significantly higher in cisplatin-treated tumor cells with higher IC50 values. Depletion of CRNDE inhibited tumor cell proliferation and colony
formation, induced cell apoptosis, and suppressed migration and invasion in medulloblastoma cells. Moreover, overexpression of miR-29c-3p inhibited tumor cell proliferation and colony formation, migration, and invasion, and enhanced apoptosis and chemosensitivity to cisplatin. In addition,
CRNDE was found to act as a miR-29c-3p sponge. Furthermore, in vivo experiments showed the CRNDE/miR-29c-3p interactions involved in medulloblastoma. Our study demonstrates that CRNDE acts as a critical mediator of proliferation, apoptosis, migration, invasion, and resistance to chemotherapeutics
via binding to and negatively regulating miR-29c-3p in medulloblastoma cells. These results provide novel molecular targets for treatment of medulloblastoma.
Design, synthesis and investigation of water-soluble hemi-indigo photoswitches for bioapplications
Authors: Berdnikova Daria V
Published: November 2019

A series of hemi-indigo derivatives was synthesized and their photoswitching properties in aqueous medium were studied. The dimethoxy hemi-indigo derivative with the best photochromic performance in water was identified as a promising platform for the development of photoswitchable binders for biomolecules. The synthetic approach towards the introduction of the alkylamino pendant to the dimethoxy hemi-indigo core was developed that allowed to obtain an RNA-binding hemi-indigo derivative with photoswitchable fluorescent properties.
Accretion Kinematics in the T Tauri Binary TWA 3A: Evidence for Preferential Accretion onto the TWA 3A Primary
Authors: Tofflemire Benjamin M. , Mathieu Robert D. , Johns-Krull Christopher M.
Published: November 2019

We present time-series, high-resolution optical spectroscopy of the eccentric T Tauri binary TWA 3A. Our analysis focuses on variability in the strength and structure of the accretion-tracing emission lines Hα and He i 5876 Å. We find emission line strengths to display the same orbital phase–dependent behavior found with time-series photometry, namely, bursts of accretion near periastron passages. Such bursts are in good agreement with numerical simulations of young eccentric binaries. During accretion bursts, the emission of He i 5876 Å consistently traces the velocity of the primary star. After removing a model for the system’s chromospheric emission, we find the primary star typically emits ∼70% of the He i accretion flux. We interpret this result as evidence for circumbinary accretion streams that preferentially feed the TWA 3A primary. This finding is in contrast to most numerical simulations, which predict the secondary should be the dominant accretor in a binary system. Our results may be consistent with a model in which the precession of an eccentric circumbinary disk gap alternates between preferentially supplying mass to the primary and secondary.
On the GeV Emission of the Type I BdHN GRB 130427A

Published: November 2019

We propose that the inner engine of a type I binary-driven hypernova (BdHN) is composed of Kerr black hole (BH) in a non-stationary state, embedded in a uniform magnetic field B
0 aligned with the BH rotation axis and surrounded by an ionized plasma of extremely low density of 10−14 g cm−3. Using GRB 130427A as a prototype, we show that this inner engine acts in a sequence of elementary impulses. Electrons accelerate to ultrarelativistic energy near the BH horizon, propagating along the polar axis, θ = 0, where they can reach energies of ∼1018 eV, partially contributing to ultrahigh-energy cosmic rays. When propagating with

through the magnetic field B
0, they produce GeV and TeV radiation through synchroton emission. The mass of BH, M = 2.31M
⊙, its spin, α = 0.47, and the value of magnetic field B
0 = 3.48 × 1010 G, are determined self consistently to fulfill the energetic and the transparency requirement. The repetition time of each elementary impulse of energy

erg is ∼10−14 s at the beginning of the process, then slowly increases with time evolution. In principle, this “inner engine” can operate in a gamma-ray burst (GRB) for thousands of years. By scaling the BH mass and the magnetic field, the same inner engine can describe active galactic nuclei.

L’activité de tissage dans les arrière-pays marocains subit de profondes transformations en raison de sa marchandisation et de son internationalisation. Le réseau d’acteurs impliqué se développe et se spécialise en jouant un rôle de « traduction » au sens de la théorie de l’acteur-réseau. Cela se fait au détriment des femmes-tisseuses qui se trouvent dans une situation de plus grande dépendance.
Gouvernance politique, diversité du genre et transition démocratique : leçons tunisiennes
Authors: Kchouk Bilel , Ben Rhouma Amel
Published: November 2019

Le rapport entre transition démocratique et percée des femmes dans la gouvernance politique constitue un objet de recherche prolifique dans la littérature politiste. Les résultats sont pourtant divergents. Pour les uns, la transition démocratique favoriserait l’évolution de la place des femmes dans les instances du pouvoir politique. Pour d’autres, il n’existe pas nécessairement de lien entre ces deux phénomènes, parfois même la transition nuirait à la représentativité des femmes. Notre recherche qui porte sur la Tunisie entre 2011 et 2016, procède selon trois logiques : une analyse statistique de l’évolution genrée du pouvoir politique depuis la chute du régime autoritaire de Ben Ali ; une étude sociographique des femmes dans les postes décisionnaires ; et un examen des perceptions de ces mêmes élites féminines sur leur place dans le nouvel échiquier politique. La confrontation des résultats de notre étude quantitative et qualitative montre qu’en dépit d’une évolution quantitative positive au sein du gouvernement et du parlement ainsi que d’une diversification sociologique de ces femmes politiques, ces dernières, très fréquemment, jugent la transition démocratique négativement en termes de représentation des femmes.
Du mouvement des droits de l’enfant à la mise en place de politiques de protection en Argentine (1989-2005)
Authors: Grimberg Julieta
Published: November 2019

Cet article s’intéresse à la diffusion et à l’appropriation du discours des droits de l’enfant en Argentine. Dans ce but, il reconstruit dans un premier temps la création d’un mouvement local pour les droits de l’enfance, en identifiant les critiques faites par les nouveaux activistes au « système tutélaire » de protection en vigueur, en analysant l’usage particulier qu’ils font de la Convention des droits de l’enfant de 1989. Ensuite, l’article explore le processus de mise en place des nouvelles politiques basées sur la perspective de la « protection intégrale des droits de l’enfant » dans la ville de Buenos Aires ; un territoire où coexistent lois nationales et locales issues de visions divergentes de ce qu’est un enfant en danger et de ce que signifie la protection de ses droits. En mettant la focale sur ce processus, l’article analyse les conflits et luttes de pouvoir qui traversent les rapports entre institutions administratives et judiciaires du champ de la protection de l’enfance et montre que les droits de l’enfant ont été l’objet d’interprétations et d’instrumentalisations diverses.
Trois continents et une île
Authors: Fejtö François
Published: November 2019

Dans cette Lettre de la Havane , l’histoirien François Fejtö décrit avec un certain sarcasme l’envers du décor de la Conférence de la Havane – la « Tricontinentale », qui pris place à Cuba du 3 au 15 janvier 1966. Du luxueux décor – destiné à l’origine aux touristes américains – aux différentes tensions qui traversent les mouvements tiers-mondistes d’alors, l’historien décrit à la fois adroitement et précisément les dissensions entre les mouvements qui composent les participants, mais aussi leurs rapports avec chacun des « frères ennemis » ; les Soviétiques et les Chinois. L’éviction ou du moins l’isolement de ces derniers semblait avoir été, au départ, un des objectifs de la conférence pour l’URSS –. Fetjö relate également les débats relatifs à la création d’une organisation tricontinentale, dont les bases sont alors jetées, qui conserve pourtant l’appareil de l’ancienne organisation, fondée sur la coopération asiatico-africaine. Ce texte apporte enfin des éléments de compréhension importants pour saisir les différentes tensions suivant le départ du Che de Cuba en 1965 – qui provoqua une crise du castrisme, bloquée entre intérêts des régimes révolutionnaires stabilisés, en voie d’embourgeoisement, et la pression des « révoltés inassouvis », exaspérés par les progrès du « colonialisme », qui « exigent une aide quasi illimitée, sacrifice sur sacrifice ».
“It May Be a Bit Uncertain But It's Never Boring”: Thematic Analysis of a Blog About Engaging With Aging
Authors: Su Yan , Zhai Shumenghui , Kim Boeun , Miyawaki Christina E. , Primomo Janet , Belza Basia
Published: November 2019

Online blogs about healthy aging written by health care professionals and others are increasing. The purpose of the current study was to analyze a first-person narrative blog about engaging with aging (EWA), with a goal of better understanding the process used to manage daily life and inform healthy aging for older adults. Using a thematic analysis approach, 67 blog posts written by a nonagenarian, retired nursing professor were analyzed. Emergent themes revealed the identification of age-related changes (e.g., physical, cognitive, functional, social, societal, psychological), characteristics of the age-related changes process, responses to age-related changes (e.g., feelings, attitudes), approaches and strategies to addressing age-related changes (i.e., the use of internal and external resources), and the outcomes of the approaches. The EWA blog posts help understand the aging experience from the perspective of an older adult, especially functional changes and how they affect daily life, as well as strategies used to adapt to changes.

Authors: Ventura Camila V. , Gois Adriana L. , Freire Bárbara O. , de Almeida Danielle C. , MacKeen Leslie D. , Ventura Filho Marcelo C. , Berrocal Audina M. , Paul Chan R.V. , Belfort Rubens , Maia Mauricio , Ventura Liana O.
Published: November 2019

BACKGROUND AND OBJECTIVE:

To evaluate the retinal and vasculature changes in infants with congenital Zika syndrome (CZS) using fluorescein angiography (FA).

PATIENTS AND METHODS:

This consecutive case series included six infants with CZS. FA and color fundus imaging were performed under general anesthesia in both eyes of all infants using a contact widefield digital imaging system. All color fundus images were obtained using a 130° field of view lens, and the FA images were captured using either a 130° or 80° field of view lens. The immunoglobulin M antibody capture enzyme-linked immunosorbent assay was positive for Zika virus in the cerebrospinal fluid samples of all infants. Other congenital infections were ruled out.

RESULTS:

The mean ± standard deviation age of the infants at the time of examination was 1.4 years ± 0.1 years (range: 1.3 years to 1.5 years). Contact fundus photographs showed macular abnormalities in seven eyes (58%) and retinal vasculature changes in two eyes (17%). FA detected macular abnormalities in all 12 eyes (100%) and retinal vasculature changes in five eyes (42%). The main retinal vasculature changes were peripheral avascularity in five eyes (42%) and microvasculature abnormalities in three eyes (25%).

CONCLUSION:

FA may be an important tool for detecting subtle macular and retinal vasculature changes in CZS.

Complete Posterior Vitreous Detachment Reduces the Need for Treatment of Diabetic Macular Edema
Authors: Anderson William , Piggott Kisha , Bao Yicheng K. , Pham Hang , Kavali Sweta , Rajagopal Rithwick
Published: November 2019

BACKGROUND AND OBJECTIVE:

To evaluate the vitreomacular interface and its relation to treatment burden for diabetic macular edema (DME) in patients without overt vitreomacular traction (VMT).

PATIENTS AND METHODS:

A retrospective cohort study of 494 eyes from 274 patients who had macular spectral-domain optical coherence tomography (SD-OCT) and did not have proliferative diabetic retinopathy, DME, or VMT at the initial visit. Posterior vitreous detachment (PVD) was categorized at the initial visit into five stages (0–4) using SD-OCT parameters alone.

RESULTS:

Two of 34 eyes (6.9%) presenting with a complete PVD required DME treatment during follow-up, whereas 144 of 460 eyes (31.3%) without a complete PVD at baseline required treatment (
P
= .001, Chi-squared). After adjusting for age, ethnicity, gender, and HbA1c, complete PVD at baseline was associated with a significant reduction in risk of DME therapy (hazard ratio: 0.18; 95% confidence interval, 0.05–0.73;
P
= .02).

CONCLUSION:

Complete PVD is independently associated with a reduced need for DME treatment.

Comparison of Observation Versus Vitrectomy for Patients With Hemorrhagic Posterior Vitreous Detachment
Authors: Mason Lauren B. , Wilhite James B. , McGwin Gerald , Swain Thomas A. , Crosson Jason N.
Published: November 2019

BACKGROUND AND OBJECTIVE:

Patients with hemorrhagic posterior vitreous detachments (HPVDs) have a high rate of retinal tears and often develop retinal detachments (RDs). This study aims to compare outcomes of 25-gauge pars plana vitrectomy (PPV) for HPVD versus an observational group.

PATIENTS AND METHODS:

Retrospective cohort study of 109 consecutive eyes of 105 patients diagnosed with HPVD; 66 eyes underwent PPV and 43 eyes were observed.

RESULTS:

Twenty-four eyes (36.4%) in the surgical group were found to have tears intraoperatively not seen preoperatively. The median time to vitreous hemorrhage (VH) resolution was significantly shorter for the PPV group, 14 days (interquartile range [IQR]: 7 days to 35 days), compared to those who were observed, 58.5 days (IQR: 30 days to 91 days) (
P
< .0001). RDs occurred more frequently among observational patients (11.63%) compared to 1.52% of surgical patients (
P
= .0344).

CONCLUSION:

Twenty-five-gauge PPV for HPVD resulted in less RDs, diagnosis of occult retinal breaks intraoperatively, and shorter time to VH resolution.

Noninvasive Structural Imaging of a Retinal Cavernous Hemangioma Using SS-OCTA and Correlation to Previously Reported Histopathology
Authors: Zheng Andrew , Boss Joseph , Rachitskaya Aleksandra V.
Published: November 2019

Optical coherence tomography angiography (OCTA) is a novel imaging modality, and its role in the clinical evaluation of patients remains to be defined. In this report, the authors describe a case of a retinal cavernous hemangioma and show that OCTA of the lesion recapitulates many structural features first described in previous histopathologic studies, including aneurysmal architecture, septated blood flow, and epiretinal membrane. Thus, OCTA provides a new, noninvasive means of studying retinal cavernous hemangioma structure, a unique capability that may also be clinically relevant to the evaluation of other pathologic retinal vascular tumors, such as capillary and racemose hemangiomas.

The primary goal of this project was to build a curriculum for pre-service science methods students utilizing online publications of the National Academies of Sciences through the National Academies Press (NAP) and other resources to completely replace a traditional text. This course redesign was necessitated by changes in state science standards, introduced at the same time, that were built on the instructional implications presented in the Framework for K-12 Science Education. Pre-service students in the methods course indicated that the use of these resources, in lieu of a traditional text, provided a richer learning experience for them.
Relationships between Models of Genetic Regulatory Networks with Emphasis on Discrete State Stochastic Models
Authors: Pal Randip
Published: November 2019

Genetic Regulatory Networks (GRNs) represent the interconnections between genomic entities that govern the regulation of gene expression. GRNs have been represented by various types of mathematical models that capture different aspects of the biological system. This chapter discusses the relationships among the most commonly used GRN models that can enable effective integration of diverse types of sub-models. A detailed model in the form of stochastic master equation is described, followed by it coarse-scale and deterministic approximations in the form of Probabilistic Boolean Networks and Ordinary Differential Equation models respectively.

The paper reviews certain integral equation approaches and related numerical methods used in studies of biomedical applications of electromagnetic fields pertaining to transcranial magnetic stimulation (TMS) and nerve fiber stimulation. TMS is analyzed by solving the set of coupled surface integral equations (SIEs), while the numerical solution of governing equations is carried out via Method of Moments (MoM) scheme. A myelinated nerve fiber, stimulated by a current source, is represented by a straight thin wire antenna. The model is based on the corresponding homogeneous Pocklington integro-differential equation solved by means of the Galerkin Bubnov Indirect Boundary Element Method (GB-IBEM). Some illustrative numerical results for the TMS induced fields and intracellular current distribution along the myelinated nerve fiber (active and passive), respectively, are presented in the paper.
Efficient Algorithm for Answering Fuzzy Medical Requests in Pervasive Healthcare Information Systems
Authors: Labbadi Wissem , Akaichi Jalel
Published: November 2019

The progress in mobile devices and wireless networks technologies has considerably contributed to integrate pervasive computing expertise in many domains with the aim of improving the quality of services and users' mobility. However, in many situations, users may face difficult situations, needing faster decisions, where classical systems impose the submission of classic queries in which crisp conditions must be carefully fixed. This inconvenience limits the potential of pervasive applications accessed by users having few times to make the right decisions. To introduce the contributions of this paper, we choose the medical domain as example. We considered a pervasive healthcare application under which physicians haven't enough time to fix carefully their queries in some emergency cases. Therefore, they are allowed to flexibly express their preferences using conjunctive fuzzy queries and to quickly receive best answers anywhere and anytime while treating patients in the shortest time and consequently free resources for eventually other urgent requests. In this work, we consider, in general, the problem of efficiently finding the top-K answers for a conjunctive fuzzy query from the top-N conjunctive query rewritings of the query. In particular, we propose an efficient algorithm called the Top-N rewritings algorithm for finding the top-N query rewritings of a medical conjunctive fuzzy query using a set of conjunctive crisp views. At the best of our knowledge, this algorithm is the first to generate, without computing all possible rewritings, the N best ones ordered according to their satisfaction degrees and that are likely to return the best K-answers for the user fuzzy query. The relevance of a query rewriting is estimated using a second algorithm called the Query-satisfaction computing algorithm proposed to estimate, through the histograms maintained to approximate the distribution of set of values returned by the rewriting and to which fuzzy predicates are related, the pertinence of a conjunctive fuzzy query rewriting rather than accessing the database relations.

Published: November 2019

As an evidence-based business process analysis method, process mining can be used to investigate variations in delivery of care. Existing approaches are only based on one data source. A variety of data sources means different domain languages and understanding, special processes workflows in various organizations, varying documentation with different goals and different designations and varying use of coding systems. This article describes a modular, rule-based information extraction algorithm based on CDA and compares it to a proprietary healthcare reference model approach and a resource-based extraction of healthcare data using the new standard FHIR. All three approaches can be used to derive models to extract clinical and patient pathways. Similarities and differences according to interoperability and process mining tasks are described. It is concluded that standards-based approaches allow for more interoperability and can be used for a wide range of systems to provide process insight, thus facilitating better healthcare management across institutional boundaries.

Published: November 2019

This article describes how the last decade has been characterized by the production of huge amounts of different types of biological data. Following that, a flood of bioinformatics tools have been published. However, many of these tools are commercial, or require computational skills. In addition, not all tools provide intuitive and highly accessible visualization of the results. The authors have developed GEView (Gene Expression View), which is a free, user-friendly tool harboring several existing algorithms and statistical methods for the analysis of high-throughput gene, microRNA or protein expression data. It can be used to perform basic analysis such as quality control, outlier detection, batch correction and differential expression analysis, through a single intuitive graphical user interface. GEView is unique in its simplicity and highly accessible visualization it provides. Together with its basic and intuitive functionality it allows Bio-Medical scientists with no computational skills to independently analyze and visualize high-throughput data produced in their own labs.

Published: November 2019

High dimension and small sample size is an inherent problem of gene expression datasets which makes the analysis process more complex. The present study has developed a novel learning scheme that encapsulates a hybrid evolutionary fuzzy-rough feature selection model with an adaptive neural net ensemble. Fuzzy-rough method deals with uncertainty and impreciseness of real valued gene expression dataset and evolutionary search concept optimizes the subset selection process. The efficiency of the hybrid-FRGSNN model is evaluated by the proposed neural net ensemble learning algorithm. Again to prove the learning capability of ensemble algorithm, performance of the component classifiers pairing with FR, GSNN and FRGSNN are compared with proposed hybrid-FRGSNN based ensemble model. In addition to this, efficiency of neural net ensemble is compared with two classical and one advanced ensemble learning algorithms.

The proactive development in electronic health (e-health) has introduced seemingly endless number of applications such as telemedicine, electronic records, healthcare score cards, healthcare monitoring etc. Yet, these applications confront the key challenges of network dependence and medical personnel necessity, which hinders the development of universality of e-health services. To mitigate such key challenges, this chapter presents a versatile wired and wireless distributed e-home healthcare system. By exploiting the benefit of body sensor network and information communication technology, the dedicated system model methodically integrates some of the comprehensive functions such as pervasive health monitoring, remote healthcare data access, point-of-care signal interpretation and diagnosis, disease-driven uplink update and synchronization (UUS) scheme and emergency management to design a complete and independent e-home healthcare system.
Pre-Implementation Case Studies Evaluating Workflow and Informatics Challenges in Private Primary Care Clinics for Electronic Medical Record Implementation
Authors: Or Calvin
Published: November 2019

Despite the potential benefits of electronic medical records (EMRs), their implementations have failed in a number of instances because of misfit between the technology design, work practices, workflows, and clinicians' needs. To promote effective design and implementation of an EMR system, the present pre-implementation study modeled the clinical workflow processes in private primary health care clinics and identified the associated gaps, weaknesses, and informatics challenges in the processes. Systematic field observations were performed to collect workflow data. Forty-three health care professionals (16 physicians and 27 clinical assistants) of fifteen private primary health care clinics were studied. The results, presented in a workflow diagram, demonstrate step-by-step details of the clinical work processes, their gaps and weaknesses, and possible improvement opportunities offered by the application of EMR. The workflow model provides important implications that may be applicable to other health care settings that plan to implement EMRs.

Breast cancer is considered as one of the life-threatening disease among woman population in developing as well as developed countries. This specific study reports on classification of breast thermograms using probabilistic neural network (PNN) with four statistical moments features mean, standard deviation, skewness and kurtosis and two entropy features, Shannon entropy and Wavelet packet entropy. The CLAHE histogram equalization algorithm with uniform and Rayleigh distributions were considered for contrast enhancement of breast thermal images. The asymmetry detection was performed by applying bilateral ratio. A total of 95 test images (normal = 53, abnormal = 42) was considered. Simulation study shows that CLAHE -RD with wavelet entropy features confirms the existence of symmetry on the right and left breast thermal images. An overall classification accuracy of 92.5% was achieved using the proposed multifeatures with PNN classifier. The proposed technique thus confirms the suitability as a screening tool for asymmetry detection as well as classification of breast thermograms.

Geographic information systems (GIS) are useful informative systems for reducing the waiting time of diagnostic imaging examinations. ArcGIS software is used to develop a digital questionnaire which is used as a data collection tool. The information concerns the patients' personal information, type of examination required and medical history. Data is collected in real time and through GPS capabilities, the patients' exact coordinates are determined. GIS applications are used to create digital maps which display the average waiting time for performing imaging tests. Questionnaire data and interactive maps are uploaded to a digital platform. Through this application, it is possible to locate patients who actually need diagnostic imaging examinations in real time. Observing the location of patients on digital maps makes it easier to redirect them to the nearest health care units with the shortest waiting time. Data can also be acquired by mobile phones.

Published: November 2019

The purpose of this article is to investigate the perception of medical information protection. The subjects were 281 students from 2 nursing students from September 1, 2015 to October 20, 2015. A total of 28 self - administered questionnaires were used. As a result, the perception of medical information protection behavior was 3.39 ± 0.51. In the fourth grade, the 'privacy protection' category was low (p = .007) and the 'communication' category was high (p = .045). In case of having experience in practice, 'privacy protection' category (p = .010) and ‘medical information management' category (p = .041) were low and 'communication' (p = .021) was high. In the 'communication' category, the perception score was high when the medical information protection law (p = .001) and the nurses' code of ethics (p = .040) were known. When the subject completed 'medical security education' (p = .004), the perception was high. In conclusion, it is necessary for schools and medical institutions to develop nursing education programs for their educational environment and role.
