Estudio cinemático en la carrera de velocidad niños 11-12 años
Authors: Díaz Espinel Diego Armando , Montenegro Arjona Oscar Alfredo
Published: September 2017

El presente documento estudia la estructura cinemática de la carrera de velocidad en niños, sobre una distancia de 50 m. 7 niñas (11.2+/-0.75 años) y 7 niños (11.7+/-0.88 años) participaron en el estudio (n=14). Se estudiaron las variables referidas a la longitud de paso, la frecuencia de paso, cantidad de pasos, medición del tiempo y la medición de la velocidad. Las variables mencionadas se registraron durante la primera mitad de la distancia (primeros 25 m), en la segunda mitad de la distancia, en la distancia total de los 50 m y en segmentos parciales cada 10 m. Se identificaron las fases de aceleración, velocidad cíclica máxima y desaceleración en la carrera de 50 m. Luego de hallar la fase de velocidad cíclica máxima, en cada uno de los evaluados, se calculó la velocidad angular del movimiento muslo-tronco. La correlación entre la máxima velocidad angular del movimiento muslo-tronco y el nivel de velocidad cíclica máxima de carrera, arrojaron valores estadísticos de interrelación fuerte (0.7). En consecuencia, la disminución en la frecuencia de paso parece ser el factor más importante que contribuye a la pérdida de velocidad con niños en edades de 11 y 12 años.
Experiencias pedagógicas lúdicas

Published: September 2017

Existen en el ámbito educativo acciones desarrolladas por los docentes para lograr que los alumnos obtengan aprendizajes significativos, es decir, conocimientos que pueden utilizar en situaciones que lo requieran. Desde la educación física, es importante conocer los conceptos que soportan algún tema, y tiene igual relevancia ponerlo en práctica para entender el vínculo que hay entre la teoría y las acciones que ejecutan los docentes, quienes finalmente, son los que transmiten conocimiento constantemente, sin reconocer que mucho de lo que se dice y se hace en el aula, es digno de replicar o comprobar en otros contextos, en donde los estudiantes van a tener la oportunidad de poner en práctica aquello que se aprende en clase. La dificultad radica en que hay poca credibilidad en lo que el docente dice y hace, en tanto que se convierte en información que se produce desde la experiencia y no se muestra como producción intelectual del docente y poco se sistematiza lo que se hace. Específicamente, en el Politécnico Colombiano Jaime Isaza Cadavid se han venido desarrollando eventos desde el Área de lúdica del programa Licenciatura en educación básica con énfasis en educación física, recreación y deportes, en donde, después de enseñar los elementos teóricos de las asignaturas, se pone en escena lo aprendido. Este proceso sin embargo, no ha sido debidamente sistematizado y organizado durante los años que se ha ejecutado (2007 – 2014), requiriendo de un análisis y una evaluación constante que es necesaria en educación para retroalimentar lo aprendido; necesidad que resuelve este trabajo y faculta a los alumnos de ser participantes activos en su proceso educativo.
La actividad física durante el quehacer policial: diagnóstico preliminar para la proyección de un módulo de educación física
Authors: González Javier Oswaldo , Pinzón Ruby , Morera López Helbert Humberto
Published: September 2017

El objetivo del presente estudio fue identificar los contextos de desarrollo de ejercicio físico durante las actividades laborales del policía colombiano como base para la proyección de un módulo de Educación Física.
Fue realizada una investigación de tipo exploratoria y descriptiva, haciendo uso de encuestas las cuales fueron aplicadas a una población de estudio (n=195) perteneciente a diferentes especialidades del departamento de Policía Meta y tres escuelas de formación de la Policía Nacional (Eduardo Cuevas, Alejandro Gutiérrez e Investigación Criminal). Los resultados mostraron una población activa joven ubicada principalmente en especialidades como el EMCAR (Escuadrón Móvil de Carabineros) y ESMAD (Escuadrón Móvil Antidisturbios), y una población mayor en especialidades como Vigilancia, SIJIN (Seccional de Investigación Criminal) y SIPOL (Servicio de Inteligencia Policial), principalmente. En general, se determinó una ausencia de actividades físicas tanto dentro como fuera de la jornada laboral del Policía, explicado principalmente por falta de programas de Educación Física en las unidades y capacitación para dirigir ejercicios físicos de corta duración dentro de la jornada laboral. Ejercicios físicos para espalda y miembros posteriores fueron los considerados para la orientación de programas de ejercicios físicos de corta duración.

Characterizing constraining forces in the alignment phase of orthodontic treatment
Authors: Gibson Christopher G. , Lin Feng-Chang , Phillips Ceib , Edelman Alex , Ko Ching-Chang
Published: September 2017

Objectives:

To describe the frictional forces (FF) that constrain wire sliding in the initial alignment phase of treatment using a new term, the “constraining force” (CF), and to hypothesize that CF is dependent on two factors: the hyperelastic behavior of archwires and the specific type of tooth geometric malalignment present.

Materials and Methods:

A laboratory device that simulates the four distinct malalignment types (in-out, rotation, tipping, and vertical step) was used to couple with an Instron testing apparatus. Incremental CF data for the four types of malalignment were recorded. Each type had five trials per increment of severity, from which the CF was averaged using 0.016-inch copper-nickel-titanium (CuNiTi) archwires.

Results:

Two types of friction curves were obtained: a traditional step function response and a power regression response. For all malalignment types, increasing degrees of irregularity increased power regression responses and CF. A severity turning point, displayed as a sudden increase in CF, occurred for each malalignment. The rotation type of malalignment yielded the lowest CF, while the vertical step type resulted in the highest CF.

Conclusions:

The data infer a hypothesis that malrotation type having weak CF might act as a limiting factor in the alignment phase to unravel the neighboring teeth. Future investigations to compare clinical and bench data can help explain more fully the constraints impeding alignment resolution and the factors governing the ability to bring malaligned teeth into alignment.
Algunas consideraciones contextuales que impulsan la formación de los grupos teatrales en Puebla / Some contextual considerations that impel the formation of the theatrical groups in Puebla
Authors: Torija Aguilar Jaime
Published: September 2017

Los grupos teatrales en Puebla han ido proliferando lenta, pero de forma constante, poco tiempo después de la academización del arte dramático en la Benemérita Universidad Autónoma de Puebla (BUAP). Este trabajo tuvo como propósito señalar algunos entornos adversos que se creen determinantes para contrarrestar la realización de los individuos en el arte dramático. La respuesta, frente a dicho contexto desfavorable, ha sido una reacción defensiva y de sobrevivencia que se manifiesta a través de la formación de grupos, con el fin de recobrar autonomía, sentido e identidad.A través de la deducción, se analiza a especialistas en conductas de la sociedad de masas, surgidas en la posmodernidad, quienes critican las razones de vida centradas en el consumo. Dicha característica general recae en la sociedad poblana en detrimento de los aspirantes y profesionistas de arte dramático de la BUAP, por un claro rechazo a sus expectativas como artistas. Al revisar algunas tendencias de la sociedad de consumo, como la obtención excesiva de bienes materiales, la desvalorización de las artes ante las ciencias y la tecnología o las políticas públicas, todo lo cual constituye un obstáculo para lograr la realización del sujeto, se constata (por la experiencia directa en el trabajo realizado con grupos de teatro) que las iniciativas para el agrupamiento buscan la reivindicación de los estudiantes como individuos. Este resultado, como se podría suponer, no cubre los requerimientos económicos, sino a la necesidad de encontrar ese sentido de existencia y de identidad que se ha perdido por la inercia del consumo.    En contracorriente de una sociedad de consumidores que impone percepciones económicas, axiológicas y estéticas, la grupalidad teatral se gesta en torno a los pequeños espacios (formales y alternativos) que permiten reivindicar la profesión, resistiendo las normas y cultura que imperan. De ser actores o directores eventuales dedicados, además, a otras actividades y con múltiples identidades, la academización de las artes, paulatinamente, ha logrado conjuntar la realización personal y la singularidad del sujeto. De esta manera, los egresados de BUAP en arte dramático (1997) se hacen presentes en la sociedad y despiertan el interés del público por el teatro.En gran parte de los ámbitos la sociedad, el arte dramático que realizan los universitarios, se ha considerado como una actividad secundaria e improductiva.  En la educación, en el ámbito familiar o en las perspectivas de los científicos, el teatro no forma parte de la cultura de un individuo. Ante dicha realidad, la misión del artista se hace mucho más compleja al sumar, entre sus actividades histriónicas, el restablecimiento de valores estéticos necesarios para sensibilizar a una sociedad.
ESTRATÉGIAS DE ENSINO PELA ÓTICA DOS ESTUDANTES: REFLEXÕES SOBRE A APRENDIZAGEM
Authors: Fonseca Sônia , Magina Sandra
Published: September 2017

O presente estudo tem por objetivo investigar as práticas pedagógicas do professor universitário pela ótica dos estudantes. Para tanto, desenvolvemos um estudo com a participação de 103 estudantes advindos de três cursos pertencentes a duas áreas distintas: exatas (licenciatura em Matemática – 25 estudantes – e Engenharia da Produção – 36 estudantes) e social (Administração – 42 estudantes). A metodologia utilizada apoiou-se nos paradigmas da pesquisa descritiva que envolveu a aplicação coletiva (com os estudantes respondendo individualmente) de um questionário e uma entrevista com características de semidirigida. Esta foi aplicada a aproximadamente 14% dos participantes, entre uma semana e 15 dias após o questionário. Os resultados da pesquisa indicam que o estudante, independente da área em que seu curso se insere e mesmo que de maneira intuitiva, consegue ter clareza entre as boas e as más práticas pedagógicas, elencando-as e avaliando-as com clareza e discernimento. O estudo concluiu que o professor universitário, independente do seu nível de titulação, carece de uma formação que contemple disciplinas didáticas para realizar a contento seu papel de formador.

Cytomegalovirus recurrence after autologous stem cell transplantation for multiple myeloma
Authors: Kabbani Dima , Iaboni Aled , Kwan Denise , Reece Donna , Husain Shahid , Rotstein Coleman
Published: September 2017

Background: Novel chemotherapeutic agents such as bortezomib and concomitant high-dose chemotherapy followed by autologous hematopoietic stem cell transplant (a-HSCT) for the treatment of multiple myeloma (MM) have increased the risk of recurrent cytomegalovirus (CMV) infection. Few studies have assessed the risk factors for CMV infection in this population. Methods: This retrospective single-centre study reviewed the incidence of, risk factors for, and treatment of CMV infection in patients with MM undergoing a-HSCT between June 2012 and May 2014. Results: Of 354 individuals who underwent a-HSCT during the study period, 242 were CMV seropositive, but 53 seropositive patients were excluded because of missing CMV viral load assessments. Of the 189 patients included in the analysis, 27 (14.3%) had a total of 28 significant CMV infections (defined by a PCR threshold >137 IU). CMV infections occurred within 3 weeks of a-HSCT. Of the patients with CMV infections, 33.3% (9/27) were symptomatic with fever. Therapy for CMV infection, however, was administered in 55.5% (15/27). Multivariate analysis identified 2 risk factors for CMV infection: baseline CMV viral load (OR 1.12, 95% CI 1.03 to 1.22; p=0.01) and receipt of a tandem a-HSCT within 6 months (HR 3.59, 95% CI 1.26 to 9.94; p=0.02). Conclusions: Further prospective studies with CMV viral load monitoring targeting patients at risk for CMV infection are needed to assess the risk, cost-effectiveness of monitoring, and benefit of pre-emptive therapy for prevention of CMV infection in such patients.
Peri-splenectomy vaccination at tertiary-care facilities in Hamilton, Ontario
Authors: Murdoch James , Shroff Anjali , Brooks Annie , Irfan Neal , O’Shea Tim
Published: September 2017

Objective: The Canadian Immunization Guide recommends vaccinations against Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type b (Hib) either at least 2 weeks before elective splenectomy or within 2 weeks following emergent splenectomy. This study aimed to assess compliance with these national recommendations. Recommended peri-splenectomy vaccines at the time of the study included the 23-valent pneumococcal polysaccharide vaccine (PPSV23), a quadrivalent meningococcal vaccine, and a Hib vaccine. Methods: Data for all adult elective and emergent splenectomy patients between March 2009 and November 2012 at an academic institution in Hamilton, Canada, were retrospectively reviewed. Data collection included indication for and date of splenectomy, vaccine formulation ordered and administered, and date of vaccine administration. Results: The vaccination rates of 125 patients were 55.2% for pneumococcus, 58.4% for meningococcus, and 59.2% for Hib; 66 patients (52.8%) received vaccinations against all three pathogens. Emergent splenectomy patients were significantly more likely than elective splenectomy patients to have documented vaccination against all three pathogens (62.9% versus 42.9%; p=0.003). Only 6 of 73 patients (8.2%) received a recommended quadrivalent meningococcal vaccine, while 49 of 69 pneumococcal-vaccinated patients (62.3%) received the recommended PPSV23. Conclusions: Peri-splenectomy vaccination patterns did not consistently meet national recommendations. Vaccines against S. pneumoniae, N. meningitidis, and Hib were administered in <60% of patients, which highlights a need for strategies to improve peri-operative vaccination rates in this population. Administration of vaccine formulations inconsistent with national guidelines demonstrates a need to improve awareness of the current vaccination recommendations for asplenic patients.
Central line associated bloodstream infections in the NICU: Does vancomycin-intermediate heteroresistance of coagulase-negative Staphylococcus matter?
Authors: Chong Jasmine , Lévesque Simon , Blanchard Ana C. , Laferrière Céline , Quach Caroline
Published: September 2017

Objective: To determine whether the duration of bacteremia among patients in the NICU, as well as risk of thrombocytopenia, differed between those with a central line associated bloodstream infection (CLABSI) due to a hetero-resistant vancomycin-intermediate Staphylococcus epidermidis (hVISE) and those whose CLABSI was due to vancomycin-susceptible S. epidermidis (VSSE). Methods: This retrospective cohort study covering the period from November 2009 through April 2014 examined records for 114 patients with coagulase-negative staphylococci (CoNS) CLABSI from two tertiary-care NICUs in Québec. Results: Of 111 patients included in the final analysis, 98 had an hVISE infection. The median duration of bacteremia was 4 days (range 0–33 days) for patients with hVISE and 4 days (range 2–8 days) for patients without hVISE. The duration of bacteremia was not significantly different between those with and without hVISE infection (B=−0.56, 95% CI −2.76 to 1.65). Further, the risk of thrombocytopenia for patients with and without hVISE was not significantly different (OR 0.42, 95% CI 0.076 to 2.72). Conclusions: hVISE was not shown to be associated with a longer duration of bacteremia or a greater risk of thrombocytopenia. This suggests that hVISE may not have a greater clinical impact than VSSE in infants with CLABSI. However, due to the small number of patients with VSSE in our cohort, firm conclusions cannot be drawn. Larger, multi-centre studies are needed to assess the true clinical relevance of vancomycin-intermediate hetero-resistant coagulase-negative staphylococci (hVICoNS) and before concluding on the need for hV identification in a clinical laboratory.
A case of group G streptococcal endocarditis masquerading as acute rheumatic fever

Published: September 2017

Cases of infective endocarditis attributable to group G streptococci are uncommon, but may be more virulent and aggressive than viridans group streptococci. This case report documents an unusual presentation of group G streptococcal endocarditis in a previously healthy young man whose initial symptoms and signs of fever, migratory polyarthritis, subcutaneous nodule, new systolic murmur, polyarthralgias, and elevated C-reactive protein (CRP) in the presence of a markedly elevated anti-streptolysin O titre fulfilled three major clinical and three minor criteria of the Revised Jones criteria, leading to an initial working diagnosis of acute rheumatic fever before echocardiography. Clinicians need to be reminded of the masquerading features of infective endocarditis.

Overpowering posterior lumbar instrumentation and fusion with hyperlordotic anterior lumbar interbody cages followed by posterior revision: a preliminary feasibility study
Authors: Kadam Abhijeet , Wigner Nathan , Saville Philip , Arlet Vincent
Published: September 2017

OBJECTIVE

The authors’ aim in this study was to evaluate whether sagittal plane correction can be obtained from the front by overpowering previous posterior instrumentation and/or fusion with hyperlordotic anterior lumbar interbody fusion (ALIF) cages in patients undergoing revision surgery for degenerative spinal conditions and/or spinal deformities.

METHODS

The authors report their experience with the application of hyperlordotic cages at 36 lumbar levels for ALIFs in a series of 20 patients who underwent revision spinal surgery at a single institution. Included patients underwent staged front-back procedures: ALIFs with hyperlordotic cages (12°, 20°, and 30°) followed by removal of posterior instrumentation and reinstrumentation from the back. Patients were divided into the following 2 groups depending on the extent of posterior instrumentation and fusion during the second stage: long constructs (≥ 6 levels with extension into thoracic spine and/or pelvis) and short constructs (< 6 levels). Preoperative and postoperative standing radiographs were evaluated to measure segmental lordosis (SL) along with standard sagittal parameters. Radiographic signs of pseudarthrosis at previously fused levels were also sought in all patients.

RESULTS

The average patient age was 54 years (range 30–66 years). The mean follow-up was 11.5 months (range 5–26 months). The mean SL achieved with 12°, 20°, and 30° cages was 13.1°, 19°, and 22.4°, respectively. The increase in postoperative SL at the respective surgically treated levels for 12°, 20°, and 30° cages that were used to overpower posterior instrumentation/fusion averaged 6.1° (p < 0.05), 12.5° (p < 0.05), and 17.7° (p < 0.05), respectively. No statistically significant difference was found in SL correction at levels in patients who had pseudarthrosis (n = 18) versus those who did not (n = 18). The mean overall lumbar lordosis increased from 44.3° to 59.8° (p < 0.05). In the long-construct group, the mean improvement in sagittal vertical axis was 85.5 mm (range 19–249.3 mm, p < 0.05). Endplate impaction/collapse was noted in 3 of 36 levels (8.3%). The anterior complication rate was 13.3%. No neurological complications or vascular injuries were observed.

CONCLUSIONS

ALIF in which hyperlordotic cages are used to overpower posterior spinal instrumentation and fusion can be expected to produce an increase in SL of a magnitude that is roughly half of the in-built cage lordotic angle. This technique may be particularly suited for lordosis correction from the front at lumbar levels that have pseudarthrosis from the previous posterior spinal fusion. Meticulous selection of levels for ALIF is crucial for safely and effectively performing this technique.
Report of a patient undergoing chronic responsive deep brain stimulation for Tourette syndrome: proof of concept

Published: September 2017

Deep brain stimulation (DBS) has emerged as a promising intervention for the treatment of select movement and neuropsychiatric disorders. Current DBS therapies deliver electrical stimulation continuously and are not designed to adapt to a patient’s symptoms. Continuous DBS can lead to rapid battery depletion, which necessitates frequent surgery for battery replacement. Next-generation neurostimulation devices can monitor neural signals from implanted DBS leads, where stimulation can be delivered responsively, moving the field of neuromodulation away from continuous paradigms. To this end, the authors designed and chronically implemented a responsive stimulation paradigm in a patient with medically refractory Tourette syndrome. The patient underwent implantation of a responsive neurostimulator, which is capable of responsive DBS, with bilateral leads in the centromedian-parafascicular (Cm-Pf) region of the thalamus. A spectral feature in the 5- to 15-Hz band was identified as the control signal. Clinical data collected prior to and after 12 months of responsive therapy revealed improvements from baseline scores in both Modified Rush Tic Rating Scale and Yale Global Tic Severity Scale scores (64% and 48% improvement, respectively). The effectiveness of responsive stimulation (p = 0.16) was statistically identical to that of scheduled duty cycle stimulation (p = 0.33; 2-sided Wilcoxon unpaired rank-sum t-test). Overall, responsive stimulation resulted in a 63.3% improvement in the neurostimulator’s projected mean battery life. Herein, to their knowledge, the authors present the first proof of concept for responsive stimulation in a patient with Tourette syndrome.

Background: Neurobiological studies implicate the amygdala and related limbic/paralimbic structures, such as the ventromedial prefrontal cortex (VMPFC), in anger and aggression. Previous studies of self-generated anger using Positron Emission Tomography (PET) have consistently documented a lack of amygdala activation during anger. Objective: We investigated the hypothesis that a lack of amygdala activation during anger is due to differences in the time course of amygdala and VMPFC activation. Specifically, we explored whether the amygdala is involved in the early phases of anger experience which is later followed by increased VMPFC activation. Methods: Eighteen healthy control participants underwent fMRI. We adapted an anger induction paradigm previously used in our PET study, in which neutral and angry states were induced using autobiographical scripts. The hypothesized time course of amygdala and VMPFC activation during acute anger induction and imagery were modeled. Region of interest (ROI) analyses were used to identify significant a priori region activation, and correlations were run between signal values and VAS anger ratings. Results: Amygdala activation increased during the acute phase of anger induction and decreased during the later phase of anger imagery, whereas VMPFC activation decreased during anger induction and increased during anger imagery, compared to the neutral conditions. In addition, negative correlations were found between self-ratings of anger and bilateral VMPFC activation. Conclusions: Overall, our results suggest that the amygdala may be active at the initial onset of anger while the VMPFC is activated over time as the individual sustains and perhaps regulates that emotional state.

Authors: Balykin V I
Published: September 2017

In the last two decades, extensive research has been devoted to the development of new ultra-small lasers. The greatest progress has been made with semiconductor lasers. A fundamentally new approach to the miniaturization of lasers is based on using plasmon instead of photon fields. This review is devoted to an interesting and rapidly developing field, the physics of plasmon lasers. This area of research is the synthesis of plasmon and laser physics, which arose as a response to the need to reduce losses in plasmonic devices. Electrodynamics, materials science, laser physics, and other aspects of the subject under consideration are considered. A comparison of photon and plasmon nanolasers is given. The fundamental and technological problems of plasmon nanolasers are discussed. Their numerous applications are also considered.

Published: September 2017

The balance of electric power and energy is important for designing power stations’ load distribution, capacity allocation, and future operation plans, and is thus of vital significance for power design and planning departments. In this paper, we analyzed the correlation between the output fluctuations of power stations and the load fluctuations of the power system in order to study the load change of the power system within a year/month/day, and the output variation amongst the power stations in operation. Reducing the output of hydropower stations or increasing the output of thermal power stations (TPS) could keep the monthly adjustment coefficient of the power system within a certain range, and thus balance the power system’s electric power and energy. The method for calculating the balance of electric power and energy of TPS is also improved. The nested-structured load shedding method (NSLSM), which is based on the calculation principle of the load shedding method, is put forward to iteratively calculate the peak shaving capacity and non-peak shaving capacity of every single thermal power station. In this way, the output process of each thermal power station can be obtained. According to the results and analysis of an example, the proposed methods of calculating monthly adjustment coefficients and the balance of electric power and energy of a thermal power station are validated in terms of correctness, feasibility, and effectiveness.
A Non-Hydrostatic Depth-Averaged Model for Hydraulically Steep Free-Surface Flows
Authors: Zerihun Yebegaeshet
Published: September 2017

This study describes the results of a numerical investigation aimed at developing and validating a non-hydrostatic depth-averaged model for flow problems where the horizontal length scales close to flow depth. For such types of problems, the steep-slope shallow-water equations are inadequate to describe the two-dimensional structure of the curvilinear flow field. In the derivation of these equations, the restrictive assumptions of negligible bed-normal acceleration and bed curvature were employed, thus limiting their applicability to shallow flow situations. Herein, a Boussinesq-type model is deduced from the depth-averaged energy equation by relaxing the weakly-curved flow approximation to deal with the non-hydrostatic steep flow problems. The proposed model is solved with an implicit finite difference scheme and then applied to simulate steady free-surface flow problems with strong curvilinear effects. The numerical results are compared to experimental data, resulting in a reasonable overall agreement. Further, it is shown that the discharge characteristics of free flow over a round-crested weir are accurately described by using a Boussinesq-type approximation, and the drawbacks arising from a standard hydrostatic approach are overcome. The suggested numerical method to determine the discharge coefficient can be extended and adopted for other types of short-crested weirs.
Adolescent Neurological Development and Implications for Health and Well-Being
Authors: Griffin Angela
Published: September 2017

Adolescence is evolution’s solution to bringing the capacity of our large, complex brains to fruition. It is a critical period for brain development and the experiences of each adolescent during this time helps to shape their adult brain. Brain developments lead to both the hormonal changes and the emotional, cognitive, and behavioral characteristics of the teenage years. They drive a growth towards independence via more complex reasoning skills, increased importance of social affiliations outside the family, and an urge to experiment and explore boundaries. In the context of still incomplete inhibitory systems, a heightened sensitivity to rewards, including the need for social acceptance, can mean risk-taking or impulsive behaviour in some. The continued plasticity of the brain can also mean a creativity and openness to novel solutions. These normative steps of adolescence are especially relevant to young people with chronic health conditions. An understanding of brain development at this time can help us appreciate the perspective and priorities of adolescents with health conditions. It can also guide us towards better ways of collaborating with them.

Authors: Han Ziqiang , Zhang Guirong , Zhang Haibo
Published: September 2017

School violence and bullying in China is under investigated, though it has become a national concern recently. Using updated national representative survey data collected in 2016 from seven provinces across China, covering students from all pre-college school types (primary, middle, high and vocational schools), this paper analyzes the prevalence of school bullying and the correlation with several school attributes. The incidences of reported bullying, bullying others and witnessing bullying are 26.10%, 9.03% and 28.90%, respectively. Primary school students are more likely to be involved in bullying behaviors. Students from elite schools (leading schools) are also more likely to be involved. Relation with teachers, relation with peers and perceived academic achievement are protective factors. Being a boy is the only significant predictor of school bullying among the family and demographic characteristics used. The results highlight the importance of school climate on preventing school violence and bullying, and a whole-school intervention approach is needed for future intervention.

Mercury content and fatty acids in muscles of Perca fluviatilis L. (European perch), Leuciscus idus L. (ide), Cyprinus carpio L. (European or common carp), Oncorhynchus mykiss Walb. (rainbow trout), Platichthys flesus L. (European flounder). and Clupea harengus L. (bream) from the Polish market were investigated. The total mercury was processed with AAS. The fatty acids were analyzed by gas chromatography. The concentration of mercury in muscles varied from 0.006 to 0.138 mg/kg and decreased as follows: perch ≈ ide > flounder > herring ≈ bream ≈ rainbow trout > carp (p ≤ 0.05). There were only significant positive correlations between body weight and mercury content in muscle tissue of carp (r = 0.878), flounder (r = 0.925) and herring (r = 0.982) (p ≤ 0.05). The atherogenic index (AI), thrombogenicity index (TI) and flesh-lipid quality index (FLQ) were calculated as follows 0.33–0.70 (IA), 0.16–0.31 (IT) and 13.01–33.22 (FLQ). Hypocholesterolemic (OFA) and hypercholesterolemic fatty acids (DFA) in muscles of fish ranged from 18.26 to 23.01 and from 73.91 to 78.46, respectively. In most cases, there were not significant correlations between size (body weight and total length) and fatty acids in the muscles of the examined fish (p > 0.05). The Target Hazard Quotient (THQ) values were below 1, which shows that there is no non-carcinogenic health risk to the consumer by consuming the examined fish.
Self-Certified Sickness Absence among Young Municipal Employees—Changes from 2002 to 2016 and Occupational Class Differences
Authors: Sumanen Hilla , Pietiläinen Olli , Mänty Minna
Published: September 2017

We examined changes in self-certified, one-to-three day sickness absence (SA) among young employees from 2002 to 2016 and the magnitude of occupational class differences during that period. All 18–34-year-old employees of the City of Helsinki, Finland were included (2002–2016, n = ~11,725 per year). Employer’s personnel and SA registers were used. Occupational class was categorized to four groups. Changes in self-certified SA from 2002 to 2016 were analyzed with Joinpoint regression and the magnitudes of occupational class differences were estimated with the relative index of inequality (RII). Most of the trends first increased and turned to decrease in 2007/2010. Managers and professionals had the least amount of SA, but steadily increasing trends were observed among men. Self-certified SA followed only partially the typical socioeconomic gradient, as routine non-manuals had the highest levels of SA. The magnitude of occupational class differences in self-certified SA was stable during the study period only among women. Self-certified SA and occupational class differences have increased in recent years among men in the lower occupational classes. Socioeconomic differences exist in self-certified SA among young employees, but gradient is only partial. Overall, high amounts of self-certified SA especially in the lower occupational classes require further studies and preventive measures.

Published: September 2017

Herein, we described the synthesis of a novel ion-imprinted membrane for the detection of palladium(II) prepared through the glutaraldehyde crosslinking of chitosan with a 4-[(4-Hydroxy)phenylazo]benzenesulfonic acid ligand trapped into the membrane. The imprinting technology was used to improve adsorption capacity and adsorption selectivity, and was combined with some advantages of the developed membrane, such as low cost and ease of preparation, water-friendly synthesis, and high biocompatible chitosan material. The membranes were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Spectrometry (EDS). The results obtained showed a high swelling ratio with a maximum value of 16.4 (1640%) at pH 4 with a strong pH dependence. Batch rebinding experiments gave a maximum adsorption capacity of 101.6 mg of Pd(II) per gram of imprinted membrane. The Pd(II) adsorption behavior was well-described by a Langmuir model with a theoretical maximum adsorption capacity of 93.48 mg g−1, similar to the experimental one. Finally, a selectivity study versus Ag(I), Pb(II), and Fe(III) ions demonstrated a good selectivity of chitosan-imprinted membrane towards Pd(II).
Meditative Movement, Energetic, and Physical Analyses of Three Qigong Exercises: Unification of Eastern and Western Mechanistic Exercise Theory
Authors: Klein Penelope , Picard George , Baumgarden Joseph , Schneider Roger
Published: September 2017

Abstract: Qigong is the meditative movement and therapeutic exercise of Eastern medicine. A growing body of evidence is validating its health benefits leading to mechanistic questions of how it works. The purpose of this article is to explore mechanisms of action related to Qigong, with the intent of unifying Eastern and Western exercise theory and to present a model for Qigong exercise analysis. Three exercises from a standardized Qigong form: ‘Plucking the Stars’, ‘Lotus Leaves Rustle in the Wind’, and ‘Pacing Forwards and Backwards’ were selected for meditative, energetic, and physical analyses. Meditative aspects include relaxation response, interoception and exteroception. Energetic aspects include stimulation of meridians through mental intent, acupressure, and self-massage. Physical aspects include flexibility, strength, articular stimulation, neuro-integration, respiratory effect, fascial stretch, visceral massage, balance challenge CranioSacral pump, lymphatic and venous return and glandular stimulation, and physiologic response to relaxation. Knowledge of mechanisms of action for specific Qigong exercises can guide operational definition of Qigong, selection of outcomes assessment in future research, inform prescriptive practice addressing clinical health issues, and advance adoption of Qigong practice within integrative health care. The model of analysis demonstrated in this discussion may assist in these endeavors.
