Social validity of a contextual behavioral science-based intervention for retirement education
Authors: Barbosa Leonardo Martins , Murta Sheila Giardini
Published: December 2019

The literature shows that retirement can bring both positive and negative effects. However, there are few tested interventions for preparing workers for this transition and avoiding or minimizing its negative impacts. This paper presents a study with multiple groups that examined the social validity of an intervention for retirement education grounded in contextual behavioral science and acceptance and commitment therapy. Twenty-seven workers aged 29 to 65 divided into three intervention groups participated (group 1,N = 15; group 2,N = 9; group 3,N = 3). According to the participants’ evaluations, the intervention provided socially valid goals, socially acceptable procedures, and socially important effects. However, some improvements are still needed, such as the use of more dynamic methods, better formatted printed material, and increased fidelity between the content’s implementation and the prescribed activities. The positive results indicate that contextual behavioral science may bolster the development of interventions whose components possess evidence for their social validity. The further evaluation of the intervention via a clinical trial study will offer more robust evidence for its effectiveness. It is hoped that by increasing the availability of theory-based interventions in this area, the present study will promote valid strategies to facilitate better adjustment to retirement.

Background

Evaluating phenotypic traits is very important for the selection of elite lines in Gossypium hirsutum L. Cotton breeders are interested in using diverse genotypes in hybridization that can segregate for traits of interested with the possibility of selection and genetic gain. Information on phenotypic and molecular diversity helps the breeders for parental selection.

Methods

In this study, 719 global collections of G. hirsutum L. were evaluated for five fibre-related traits during two consecutive years in eight different environments. A series of phenotypic data for fibre quality traits were obtained and the elite accessions were further screened using principal component analysis and phylogenetic tree construction based on single nucleotide polymorphism markers.

Results

We found that fibre quality traits showed a wide range of variation among the G. hirsutum accessions over 2 years. In general, accessions from outside China tended to have higher fibre length (FL) and fibre strength (FS) than did Chinese accessions. Among different regional accessions in China, North/Northwest accessions tended to have the highest FL, FS and best fibre macronaire. By assessing five fibre quality traits over 2 years with genotypic data, 31 elite germplasms reaching double-thirty quality values (FL ≥ 30 mm and FS ≥ 30 cN·tex− 1) were selected.

Conclusions

This study provided a detailed phenotypic diversity description of a population representing a wide range of upland cotton germplasm. Our findings provide useful information about possible elite fibre quality parents for cotton breeding programs.
Facial expression recognition using three-stage support vector machines
Authors: Dagher Issam , Dahdah Elio , Al Shakik Morshed
Published: December 2019

Herein, a three-stage support vector machine (SVM) for facial expression recognition is proposed. The first stage comprises 21 SVMs, which are all the binary combinations of seven expressions. If one expression is dominant, then the first stage will suffice; if two are dominant, then the second stage is used; and, if three are dominant, the third stage is used. These multilevel stages help reduce the possibility of experiencing an error as much as possible. Different image preprocessing stages are used to ensure that the features attained from the face detected have a meaningful and proper contribution to the classification stage. Facial expressions are created as a result of muscle movements on the face. These subtle movements are detected by the histogram-oriented gradient feature, because it is sensitive to the shapes of objects. The features attained are then used to train the three-stage SVM. Two different validation methods were used: the leave-one-out and K-fold tests. Experimental results on three databases (Japanese Female Facial Expression, Extended Cohn-Kanade Dataset, and Radboud Faces Database) show that the proposed system is competitive and has better performance compared with other works.

Published: December 2019

Resistant starch (RS) encompasses those forms of starch which are not accessible to human digestive enzymes and are fermented in the colons producing short chain fatty acids. The plant materials containing RS are few in the world. In this contribution, the culture ability of callus from anthers of F1 plants from, landraces, ‘Zhaxima’(Oryza sativa var. indica, high-RS rice line with 7.705 ± 0.142, g/100 g) × ‘Nanjing 46’ (Oryza sativa var. japonica, rice variety with RS content (g/100 g) of 0.200 ± 0.001 crosses were studied for obtaining high RS rice plants. The results showed that when M8 basic induction medium was added with 1.5 mg /L 2,4-D、2 mg /LNAA and 0.3 mg /L KT, the inductivity of callus was high as 32.14% for 21 d after pretreatment at 4 °C for 3 d; When MS differentiation basic medium was added with 2 mg /LKT and 3 mg /L ABA, the frequency of regeneration for callus was 50.3% with only a regeneration frequency of 4.55% grown into green seedlings. The RS content in the seeds was between those of the two parents and was partially normally distributed, the highest RS contents of the regenerated plants was as high as 7.66 ± 1.197%. This produced an efficient technology for regenerating stable rice lines with high RS and good eating quality using anthers culture.

Authors: Rashad Nearmeen M. , Saraya Yasser S. , Afifi Samir A. , Ali Ayman E. , Al-sayed Radwa M.
Published: December 2019

Background

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine co-morbidity of obesity. Ghrelin is a peptide which regulates food intake and body weight. The aim of this study was to measure ghrelin levels in obesity and PCOS and to evaluate the impact of weight loss on plasma ghrelin level, metabolic, and phenotypic features of PCOS. This prospective comparative study enrolled obese women without PCOS (N = 60) and obese PCOS women (n = 50) and 85 control groups. Body compositions including fat mass (FM) and fat-free mass (FFM) were measured by dual-energy X-ray absorptiometry (DEXA). Plasma ghrelin concentrations were measured using enzyme-linked immunosorbent assay (ELISA).

Results

Our results revealed that plasma ghrelin levels were lower in PCOS patients compared to obese (9.49 ± 5.59 ng/ml) and controls (48.21 ± 21.09 ng/ml). Moreover, it was negatively correlated to anthropometric measures, glycemic, lipid profile, and the phenotype characteristics of PCOS. Interestingly, after 12 weeks of following the Mediterranean diet (MD)-based weight loss program, ghrelin levels were increased in both obese groups.

Conclusion

Successful weight loss leads to increase ghrelin levels in both obese and PCOS groups.
Medical Management of Patients After Atypical Femur Fractures: a Systematic Review and Recommendations From the European Calcified Tissue Society
Authors: van de Laarschot Denise M , McKenna Malachi J , Abrahamsen Bo , Langdahl Bente , Cohen-Solal Martine , Guañabens Núria , Eastell Richard , Ralston Stuart H , Zillikens M Carola
Published: December 2019

Context

Atypical femur fractures (AFFs) are serious adverse events associated with bisphosphonates and often show poor healing.

Evidence acquisition

We performed a systematic review to evaluate effects of teriparatide, raloxifene, and denosumab on healing and occurrence of AFF.

Evidence synthesis

We retrieved 910 references and reviewed 67 papers, including 31 case reports, 9 retrospective and 3 prospective studies on teriparatide. There were no RCTs. We pooled data on fracture union (n = 98 AFFs on teriparatide) and found that radiological healing occurred within 6 months of teriparatide in 13 of 30 (43%) conservatively managed incomplete AFFs, 9 of 10 (90%) incomplete AFFs with surgical intervention, and 44 of 58 (75%) complete AFFs. In 9 of 30 (30%) nonoperated incomplete AFFs, no union was achieved after 12 months and 4 (13%) fractures became complete on teriparatide. Eight patients had new AFFs during or after teriparatide. AFF on denosumab was reported in 22 patients, including 11 patients treated for bone metastases and 8 without bisphosphonate exposure. Denosumab after AFF was associated with recurrent incomplete AFFs in 1 patient and 2 patients of contralateral complete AFF. Eight patients had used raloxifene before AFF occurred, including 1 bisphosphonate-naïve patient.

Conclusions

There is no evidence-based indication in patients with AFF for teriparatide apart from reducing the risk of typical fragility fractures, although observational data suggest that teriparatide might result in faster healing of surgically treated AFFs. Awaiting further evidence, we formulate recommendations for treatment after an AFF based on expert opinion.

Authors: Bruellman Ryan J , Watanabe Yui , Ebrhim Reham S , Creech Matthew K , Abdullah Mohamed A , Dumitrescu Alexandra M , Refetoff Samuel , Weiss Roy E
Published: December 2019

Context

Congenital hypothyroidism (CH) is due to dyshormonogenesis in 10% to 15% of subjects worldwide but accounts for 60% of CH cases in the Sudan.

Objective

To investigate the molecular basis of CH in Sudanese families.

Design

Clinical phenotype reporting and serum thyroid hormone measurements. Deoxyribonucelic acid extraction for whole-exome sequencing and Sanger sequencing.

Setting

University research center.

Patients

Twenty-six Sudanese families with CH.

Intervention

Clinical evaluation, thyroid function tests, genetic sequencing, and analysis. Our samples and information regarding samples from the literature were used to compare TG (thyroglobulin) and TPO (thyroid peroxidase) mutation rates in the Sudanese population with all populations.

Results

Mutations were found in dual-oxidase 1 (DUOX1), dual-oxidase 2 (DUOX2), iodotyrosine deiodinase (IYD), solute-carrier (SLC) 26A4, SLC26A7, SLC5A5, TG, and TPO genes. The molecular basis of the CH in 7 families remains unknown. TG mutations were significantly higher on average in the Sudanese population compared with the average number of TG mutations in other populations (P < 0.05).

Conclusions

All described mutations occur in domains important for protein structure and function, predicting the CH phenotype. Genotype prediction based on phenotype includes low or undetectable thyroglobulin levels for TG gene mutations and markedly higher thyroglobulin levels for TPO mutations. The reasons for higher incidence of TG gene mutations include gene length and possible positive genetic selection due to endemic iodine deficiency.
Neutron dose and its measurement in proton therapy—current State of Knowledge
Authors: Hälg Roger Antoine , Schneider Uwe
Published: December 2019

Proton therapy has shown dosimetric advantages over conventional radiation therapy using photons. Although the integral dose for patients treated with proton therapy is low, concerns were raised about late effects like secondary cancer caused by dose depositions far away from the treated area. This is especially true for neutrons and therefore the stray dose contribution from neutrons in proton therapy is still being investigated. The higher biological effectiveness of neutrons compared to photons is the main cause of these concerns. The gold-standard in neutron dosimetry is measurements, but performing neutron measurements is challenging. Different approaches have been taken to overcome these difficulties, for instance with newly developed neutron detectors. Monte Carlo simulations is another common technique to assess the dose from secondary neutrons. Measurements and simulations are used to develop analytical models for fast neutron dose estimations. This article tries to summarize the developments in the different aspects of neutron dose in proton therapy since 2017. In general, low neutron doses have been reported, especially in active proton therapy. Although the published biological effectiveness of neutrons relative to photons regarding cancer induction is higher, it is unlikely that the neutron dose has a large impact on the second cancer risk of proton therapy patients.
Verification of a Monte Carlo dose calculation engine in proton minibeam radiotherapy in a passive scattering beamline for preclinical trials
Authors: Guardiola Consuelo , De Marzi Ludovic , Prezado Yolanda
Published: December 2019

Objectives:

Proton minibeam radiation therapy (pMBRT) is a novel therapeutic strategy that combines the benefits of proton therapy with the remarkable normal tissue preservation observed with the use of submillimetric spatially fractionated beams. This promising technique has been implemented at the Institut Curie-Proton therapy centre (ICPO) using a first prototype of a multislit collimator. The purpose of this work was to develop a Monte Carlo-based dose calculation engine to reliably guide preclinical studies at ICPO.

Methods:

The whole “Y1”-passive beamline at the ICPO, including pMBRT implementation, was modelled using the Monte Carlo GATE v. 7.0 code. A clinically relevant proton energy (100 MeV) was used as starting point. Minibeam generation by means of the brass collimator used in the first experiments was modelled. A virtual source was modelled at the exit of the beamline nozzle and outcomes were compared with dosimetric measurements performed with EBT3 gafchromic films and a diamond detector in water. Dose distributions were recorded in a water phantom and in rat CT images (7-week-old male Fischer rats).

Results:

The dose calculation engine was benchmarked against experimental data and was then used to assess dose distributions in CT images of a rat, resulting from different irradiation configurations used in several experiments. It reduced computational time by an order of magnitude. This allows us to speed up simulations for in vivo trials, where we obtained peak-to-valley dose ratios of 1.20 ± 0.05 and 6.1 ± 0.2 for proton minibeam irradiations targeting the tumour and crossing the rat head. Tumour eradication was observed in the 67 and 22% of the animals treated respectively.

Conclusion:

A Monte Carlo dose calculation engine for pMBRT implementation with mechanical collimation has been developed. This tool can be used to guide and interpret the results of in vivo trials.

Advances in knowledge:

This is the first Monte Carlo dose engine for pMBRT that is being used to guide preclinical trials in a clinical proton therapy centre.

Authors: Park Ko Woon , Han Sol Bee , Han Boo-Kyung , Ko Eun Sook , Choi Ji Soo , Rhee Sun Jung , Ko Eun Young
Published: December 2019

Objective:

To compare the diagnostic performance of breast MRI with abbreviated protocol (AB-MRI) and full ddiagnostic protocol (FDP-MRI) for surveillance of females with a personal history of breast cancer

Methods:

In this retrospective study, we analyzed the outcomes of total 1312 post-operative screening breast MRI matched from 1045 AB-MRI and 677 FDP-MRI, which had histologic confirmation for suspicious MRI findings or 1 year negative follow-up images. This study was approved by the institutional review board and informed patient consent was waved. AB-MRI consists of T  2 weighted scanning and dynamic contrast-enhanced imaging including one pre-contrast and two post-contrast scans. We compared the diagnostic performance for recurrent breast cancer in terms of sensitivity, specificity, positive-predictive value, negative-predictive value, and accuracy and area under the curve between the screening AB-MRI and FDP-MRI.

Results:

Overall, 13 recurrent tumors among 1312 post-operative cases screened with breast MRI (1.0%) were detected including 8 invasive cancer, 2 cases of in situ cancer, and 3 cases of metastatic lymph nodes. The sensitivity and negative predictive value were 70 vs 100 and 99.5% vs 100% in AB-MRI and FDP-MRI. Specificity, positive predictive value, accuracy, and area under the curve of AB-MRI and FDP-MRI were 98.0% vs 96.9%, 35.0% vs 23.1%, 97.6% vs 97.0%, and 0.840 vs 0.985, respectively.

Conclusion:

The performance of AB-MRI was comparable to that of FDP-MRI in detecting recurrent breast cancer and decreased false positive cases.

Advances in knowledge:

AB-MRI provides a reliable alternative with similar diagnostic performance and shorter MRI acquisition time.

Authors: AYDIN Gulsum , YILDIRIM Kenan , KALEMTAS Ayse
Published: December 2019

In this study, a simple, innovative approach is applied to produce porous a-TCP-CeO2-Al2O3 composite beads via using bovine bone-derived hydroxyapatite, cerium oxide, and alumina ceramics. Bovine-bone derived hydroxyapatite was obtained via calcination of bones at 950°C for 3 hours. Hydroxyapatite is a thermally unstable biomaterial at high temperatures, and depending on its stoichiometry decomposes at 800-1200°C. Sodium alginate was successfully used as an in situ gelling templates for the production of the ceramic beads and starch, an environmentally friendly and economic pore-forming agent, is used to achieve interconnected, highly open porosity containing composite beads. Sintering of the ceramic−starch−alginate green composite beads at 1200°C for 1 hour resulted in the decomposition of the hydroxyapatite phase and formation of a-TCP. XRD analysis revealed that a-TCP-CeO2-Al2O3 composite beads were achieved. XRD analysis confirmed the formation of a-TCP phase in all composite compositions. SEM investigations of the produced composite beads revealed that bimodal pore size distribution, fine and coarse, was achieved.

The performance of a flat plate solar collector with thin absorber is studied. The temperature of the absorber and its variation along the local day time is obtained by solving a heat balance equation. The temperature of the working fluid is also estimated. A published solar source functionto predict the hourly daily incident solar irradiance on horizontal surface is considered. Five absorbers of different materials: Copper, Aluminum, Stainless steel, Glass and Mica are treated. Two cooling conditions at the absorber front irradiated surface are also taken into consideration. Factors affecting its efficiency are revealed.

Published: December 2019

Introduction

The diagnostic performance of ultrasound-fine needle aspiration to identify thyroid nodules harbouring malignancy remains variable. The aim of this study was to determine thyroid nodule size and cytological classification as predictors of malignancy risk.

Materials and methods

We conducted a retrospective cohort analysis at an academic hospital involving 499 consecutive patients who underwent thyroid surgery between 2004 and 2015.

Results

A total of 503 thyroid nodules (499 patients, 84% female; mean age 50.8 years, standard deviation, SD, 15.4 years) were analysed. Of these, 19.5% were malignant. The mean (± SD) nodule size was 3.28 ± 1.63 cm and 3.27 ± 1.54 cm for benign and malignant nodules, respectively. The odds of malignancy for thyroid nodules less than 3.0 cm was similar to those for nodules of 3.0 cm or greater (0.26 compared with 0.29; p=0.77). Overall, the sensitivity and specificity of fine-needle aspiration in this cohort were 71.4% and 100%, respectively. The overall false negative rate was 5.4%. When the cut-off of 3.0 cm was used, the false negative rate in thyroid nodules less than 3.0 cm was 0% compared with 7.0% in nodules of 3.0 cm or greater. Thus, class (p<0.01) but not nodule size (p=0.49), was associated with higher malignancy risk.

Conclusions

Our results suggest that thyroid nodule size did not accurately predict the risk of thyroid malignancy irrespective of fine-needle aspiration cytology. Routine diagnostic thyroid lobectomy solely owing to thyroid nodule size of 3.0 cm or greater is currently not justified.

Many scientists assume that RCM output is directly used as input for climate change impact models, while it consists of systematic errors. Consequently, RCM still requires bias correction to be used as an input model. The purpose of this study was to analyze the RCM performance before and after bias correction, its best performance from several models, as well as to clarify the importance of bias correction before it is used to analyze climate change. As a result of this, the method used for bias correction was Distribution Mapping method (for rainfall) and Average Ratio-method (for air temperature). While the Generalized Extrem Valuedistribution (GEV) was used to analysis extreme rainfall. To determine the performance of the model before and after bias correction, statistical analysis was used namelyR2, NSE, and RMSE. Furthermore, ranking for every single model and Taylor Diagram was used to determine the best model. The results showed that the RCMs performance improved with bias correction. However, CSIRO-Mk3-6-0, CCSM4, GFDL-ESM2M, and MPI-ESM-MR models can be ignored as ensemble models, because they demonstrated poor performance in simulating rainfall. From this study, it was suggested that the best model in simulating daily and monthly rainfall was ACCESS1-0, while MIROC-ESM-CHEM (daily air temperature) and ACCESS1-0 (monthly air temperature) were best models used in simulating air temperature. Key words: RCM, bias correction, performance, rainfall, air temperature

Published: December 2019

Two types of ultra–broadband long wavelength infrared (LWIR) absorbers with small period and super thin thickness are designed. The absorption with high absorptivity and large bandwidth is achieved through combined propagating and localized surfaced plasmon resonances. We first design a three-layer absorber with a Ti–Ge–Ti configuration, the period of the structure is only 1.4 µm (nearly 1/8 of the center wavelength), the thickness of its dielectric is only 0.5 µm (1/22 of the center wavelength), and the average absorption is 87.9% under normal incident from 8µm to 14µm. Furthermore, the four-layer absorber with a Ti–Ge–Si3N4–Ti configuration is designed to obtain more average absorption increasing to 94.5% from 8 µm to 14µm under normal incident, the period of the structure increases to 1.6 µm and the total thickness of dielectric increases to 0.6µm. The proposed absorber is polarization–independent and possesses a good tolerance of incident angle. We calculate that the average absorption of the four-layer absorber for both TE– and TM–modes still exceeds 90% up to an incident angle of θ = 40° (90.7% for TE–mode, 91.9% for TM–mode), and exceed 80% up to an incident angle of θ = 60° (80.2% for TE–mode, 82.1% for TM–mode).
Time-moduated non-reciprocal metasurface absorber for surface waves
Authors: Li Aobo , Li Yunbo , Long Jiang , Forati Ebrahim , Du Zhixia , Sievenpiper Dan
Published: December 2019

We have investigated a magnet-free, nonreciprocal surface wave absorber
based on high impedance surfaces (HISs) using a spatial-temporal
modulation approach. By controlling embedded switches with a
travelling wave, the HIS metasurface is modulated to break the time
and spatial symmetry, which enables surface waves to propagate in one
direction but be absorbed when propagating in the reverse direction.
The nonreciprocity has been demonstrated by an EM-circuit
co-simulation. We envision that this could be possibly applied in
future communication systems that preferably transmit unidirectionally
but absorb interference from the reverse direction caused by
reflections or other devices.

Based on our results, we proposed a model for an optical router and transistor (amplifier and switch). The router action results from the SAT- and TAT-splitting while the transistor was realized by a switch from bright to dark dressed states.
Microwave photonic notch filter with a tunable frequency and a bandwidth based on gas absorption
Authors: Yuan Ziyue , Lou Xiutao , Dong Yongkang
Published: December 2019

We propose and demonstrate a high-performance microwave photonic notch filter (MPNF) based on gas absorption with favorable tunability and a high rejection ratio. In the demonstration experiments, acetylene gas is used to selectively absorb the single sideband produced by phase modulation, and correspondingly to suppress the generated microwave signal. The filter center frequency and bandwidth can be separately tuned by changing the carrier laser frequency and gas pressure. The proposed MPNF achieves a continuously tunable frequency from 2–20 GHz and a 10-dB bandwidth from 0.44–5.89 GHz with a high rejection ratio over 60 dB, which is expected to exceed 100 dB in theory, showing great potential for various applications such as advanced communication and radar.

Différance Animal/ Humano: deconstrucción epistemológica
Authors: Zarzo Esther
Published: December 2019

Esta investigación recupera los análisis deconstructivos sobre el límite teórico entre los conceptos de “animalidad” y “humanidad” que Jacques Derrida realiza en numerosos lugares de su obra, aunque muy especialmente en el recopilatorio de conferencias El animal que luego estoy si(gui)endo. En primer lugar, se ofrece una explicación sintética de la deconstrucción histórica y epistemológica realizada por Derrida del par “animal” / “humano”, explicitando con ello el proceso moderno de definición por el cual tales categorías naturalizan y perpetúan la violencia estructural contra los seres categorizados bajo el concepto “animal”. En segundo término, se clarifican los puntos débiles de tales categorizaciones detectados por el análisis deconstructivo, y cuya paradójica consecuencia es la crisis del concepto de “sujeto” que pretendía encumbrar. En tercer lugar, se describe la estrategia derridiana para redefinir tales categorías de forma no excluyente y susceptible de reconocimiento ético.
Los dragones en la cultura occidental y en la oriental: dos cuentos tradicionales, San Jorge y el dragón y La perla y el dragón
Authors: Segura Zariquiegui Ainhoa
Published: December 2019

Existen diversos seres mitológicos en todas las culturas del mundo. El dragón es uno de esos seres cuya representación surge en remotos tiempos. Además, se trata de la imagen tomada por China como representación de su poder, arte y cultura, y adorada desde hace miles de años. Este ser mitológico también surgió en Occidente. En la cultura occidental existe una variación a la hora de representar el dragón, en algunos momentos posee un significado negativo y en otros momentos positivo. En cambio, en Oriente, por influencia del taoísmo tiene características ambivalentes al mismo tiempo. En este artículo se va a tratar del tema de la historia del origen del dragón en Occidente y Oriente, y además, del reflejo de este ser mitológico en los cuentos tradicionales de ambas culturas.
“Something Awful”: fronteras difusas y conexiones místicas entre lo animal, lo humano y lo divino en dos relatos de Flannery O’Connor
Authors: Correoso Ródenas José Manuel
Published: December 2019

El objetivo de este artículo es poner de relieve dos de los relatos que Flannery O’Connor incluyó en su MFA Thesis en el Iowa Writers’ Workshop (1947): “Wildcat” y “The Turkey”. En ambos, como se puede desprender de los títulos, aparecen animales que tienen una capital importancia para el desenlace de las historias. En ambos, también, aparecen hombres (o niños) cuya vida está ligada a la de estos animales. No obstante, tanto el gato salvaje como el pavo silvestre, bajo la óptica que Flannery O’Connor ofrece, no son sólo representantes del mundo animal, sino que se erigen en modos o vías de unión con la divinidad. A través de ellos, los personajes humanos pueden trascender el mundo terreno y alcanzar lo intangible, descubriendo, muchas veces, que esta otra realidad es más terrible de lo que imaginaban. Ambas bestias son dignas poseedoras de los “mystery and manners” que la escritora de Milledgeville situaba en el centro de su producción: son (y encarnan) un misterio y, a la vez, buscan las costumbres de los hombres para arrastrarlos al otro lado. En estos textos, las fronteras entre lo humano, lo animal y lo divino parecen desaparecer, creando un continuo híbrido a tres bandas del que se torna imposible escapar para los protagonistas. La muerte, como puerta, será la única salida que encuentren.
Incursión en la ecocrítica francófona: estudio de una novela quebequense a través del devenir-animal
Authors: Voyer Véronique
Published: December 2019

En este artículo, se cuestiona cómo la biología y la filosofía pueden aportar nuevos puntos de vista para pensar la literatura. ¿Es ésta una perspectiva plausible, productiva? Para explorar esta problemática, basé mi análisis en la teoría filosófica del devenir-animal (Deleuze y Guattari, 1980). Este concepto visibiliza el deseo de transformación y su proceso. Para llevar a cabo este proyecto he indagado en la obra del quebequense Robert Lalonde titulada Le monde sur le flanc de la truite: notes sur l'art de voir, de lire et d'écrire (El mundo sobre el costado de la trucha: Apuntes sobre el arte de ver, leer y escribir). Estructurado alrededor de las cuatro estaciones del año, el relato del escritor propone un diálogo entre los pasajes de sus autores favoritos y los devenires que le inspira la vida en el campo. En un bosque canadiense, su vida cotidiana transcurre entre la naturaleza y la lectura. Aislado, el escritor mestizo pone en valor la presencia de los animales y se vuelve el nexo entre unos elementos heterogéneos, por ejemplo, emparejando fauna y autores en esta narración inspirada en su ascendencia mohawk. Una multiplicidad de universos se solapa en la obra de Robert Lalonde, y la mayoría de estos medios borran las fronteras entre lo humano y lo animal. A través de la escritura, el autor toma varias formas de vidas no humanas prestadas para adaptar sus percepciones (intensidad, potencial, velocidad, capacidad, etc.) en otro entorno en el cual algunos elementos cambian. El análisis del libro de Robert Lalonde partiendo de la teoría del devenir-animal permite, de este modo, pensar la relación heterogénea que se da entre el entorno y el lenguaje. Así, la idea del entorno no se limita al animal: se abre también al lenguaje, a la traducción y a las transferencias culturales.
Aportes críticos a la implementación del Seminario de Ciencias Sociales en las escuelas secundarias rosarinas
Authors: Pereyra Lucchese Emiliano León
Published: December 2019

El presente artículo es una reflexión acerca de cómo se implementó el espacio curricular Seminario de Ciencias Sociales en las escuelas secundarias de la ciudad de Rosario, tras la reforma curricular que se produjo en la provincia de Santa Fe en el año 2014. El trabajo propone un recorrido por las ciencias sociales en la escuela, el problema de la interdisciplinariedad en la secundaria disciplinar y un paneo acerca de cómo se trabaja en distintas escuelas este espacio. Se historiza cómo surgió este espacio curricular articulado, tanto en la teoría (análisis de normativa nacional y provincial, concepciones didácticas que lo sustentan, programas provinciales) como en la práctica (análisis a nivel aúlico a través de entrevistas, encuestas y planificaciones). Se concluye que una de las razones por la cuál el Seminario en Ciencias Sociales presentó serias dificultades para su implementación fue el carácter interdisciplinario que se propone en una escuela (y una formación docente) disciplinaria.
La Base Nacional Curricular Común (BNCC) del Brasil y la componente "historia". El debate en Río de Janeiro de 2015-2016 y la experiencia del Observatorio de la BNCC/UFF
Authors: Secreto María Verónica
Published: December 2019

El presente trabajo se funda el debate colectivo desarrollado en el departamento de Historia Universidad Federal Fluminense, a través del Observatorio de la BNCC. Entendemos que es necesaria una historia que permita comprender la diversidad de las experiencias humanas en el tiempo y el espacio, como era establecido en la Ley de Directrices Básicas. A partir de lo enunciado se consideró que, cuando se enseña la historia de Brasil, debe tener en cuenta las contribuciones de las diferentes culturas y etnias para la formación del pueblo brasileño, especialmente de las matrices indígena, africana y europea, pero estando atentos al sentido procesual y no "esencial" en la formación de los grupos humanos. El presente es un ejercicio de reflexión, mucho más que una prescripción o una pretensión de prescripción y busca ampliar el debate sobre las formas de jerarquizar los discursos a partir de las incumbencias disciplinarias.

Authors: Margiyati Margiyati , Dwidiyanti Meidiana , Wijayanti Diyan Yuli
Published: December 2019

Background: Smoking is a habit that causes many health problems. Nicotine substances in cigarettes cause addiction and carbon monoxide inhaled is poisonous. Hypnotherapy using induction hanung technique is an alternative which can be used to change someone’s smoking behaviors. This therapy is performed by giving hypnotic suggestions combined with a massage at acupuncture points of neguan, yintang, and taiyang. Purpose: This study aimed to analyze the effects of hypnotherapy using induction hanung technique on the level of cigarette dependence and carbon monoxide in exhaled breath among active smokers in Kesdam IV/ Diponegoro College of Nursing, Semarang.Methods: The present study employed a true-experimental pretest-posttest control group design. A total of 40 students were recruited as samples and randomly assigned to the intervention group (n=20) and control group (n=20). The intervention in the form of hypnotherapy using induction hanung technique was given for six times in two weeks. The instruments used were Fagerstorm Test for Cigarette Dependence (FTCD) and smokerlyzer. Data were analyzed with the Mann-Whitney test and independent t-test.Results: The results showed a decrease in the score of cigarette dependence level in the intervention group by 1.25 after the intervention was given with pretest mean value of 1.45 (SD=1.132). The result of Mann-Whitney test showed a significant difference in the cigarette dependence score between the intervention and control groups with a pvalue of 0.028. The level of carbon monoxide in the exhaled breath also decreased by 8.80 ppm after the intervention from the pretest mean values of 12.55 (SD=6.669). The independent sample t-test result also showed a significant difference in the carbon monoxide level between the two groups with a p-value of 0.000.Conclusion: The present findings showed that hypnotherapy using induction hanung technique affected the level of cigarette dependence and carbon monoxide in exhaled breath among the active smokers. Based on the findings, this therapy is recommended as an alternative to nursing intervention for the smoking cessation programs.

Published: December 2019

Background: Public health services today require community empowerment so that services become affordable in every village in the community. Health cadres are existing non-professional health workers who are trained to be able to support patients or the community in addressing health problems faced. Health cadres as non-professionals who are directly dealing with the community are required to increase their ability continuously according to the changes that occur in the community.Purpose: The purpose of this study is that health cadres can improve their understanding holistically about health, through the SI-SEHO application tool so that health cadres can monitor the health of patients in the community.Method: The research used is descriptive using a qualitative approach obtained from the results of empowerment and cadre training activities using the SI-SEHO application. Data analysis is based on the objectives of the training on the use of the SI-SEHO application.Results: The results of this research activity are that health cadres can understand the meaning of health holistically that is inseparable from several dimensions of understanding holistic health. As stated by SP respondent 4 "Holistic health is comprehensive health, such as body and mind health." The ability of cadres to help individuals, families and communities increase with cadres saying "now we can help others in the community by registering through applications". Other results were obtained from research subjects as several people had been detected with physical illness and some people were detected at risk for mental disorders.Conclusion: The use of information technology is able to improve the knowledge and ability of health cadres in monitoring sick individuals or patients in the community. The development of health information systems is currently needed in the development of health services in today's digital era, such as empowering health cadres through information system training.

MIRD has developed methods, assumptions, models, and mathematical formulae for estimating internal radiation doses from the injected radiopharmaceuticals into the body. This study aims to determine the radiopharmaceutical distribution of Cobalt 57 MIBI in patients identified as having breast cancer by using an oncology examination with MIRD method on 4 patient's organs with some time variations. The four organs of the patient's body are the heart, thyroid, kidney, and liver. The MIRD method developed to calculate the absorption dose of each organ is the product of the cumulative activity and the S factor of each organ studied. The results showed that the highest uptake dose in these patients was in the thyroid and kidney organs, and then followed by the heart and liver. These results indicate that the thyroid and kidney organs are the most vulnerable organs by the method of injecting radiopharmaceutical doses into the body of breast cancer patients.
