Full Text Available El presente artículo analiza la praxis pedagógica en Hans Steffen como profesor en el Instituto Pedagógico de Santiago, entre fines del siglo XIX y comienzos del XX. En un sentido, se define el marco en el cual este concibió a la disciplina geográfica, particularmente en Alemania. Aquí se busca determinar los principales tópicos y discusiones que permitieron que dicha materia se transformara en una disciplina científica institucionalizada. En segundo lugar, se analizan las lecturas que hizo Steffen de tales tópicos y discusiones de modo de identificar sus influencias. Finalmente, se estudia cómo tales tópicos y discusiones se transfirieron a sus clases en el Instituto Pedagógico, como a los planes y programas de estudio de la geografía que Steffen ayudó a redactar para el sistema educativo chileno entre 1893 y 1907.This article discusses the educational praxis in Hans Steffen as a professor at the Pedagogical Institute of Santiago between the late nineteenth and early twentieth centuries. In a sense this work defines the framework in which Steffen conceived the discipline of geography, particularly in Germany. This article looks to determine the main topics and discussions that allowed this subject matter to be transformed into an institutionalized scientific discipline. Second, it analyzes the materials that Steffen read on different topics and discussions in order to identify his influences. Finally, we study how such topics and discussions were applied to their classes at the Pedagogical Institute, as to the plans and programs for the study of geography that Steffen helped to write for the Chilean educational system between 1893 and 1907.

En este propósito han campeado estrategias de corte heterónomo y autónomo, sin embargo, paradójicamente, la descomposición del tejido social es de tal gravedad que sólo nos ofrece un camino, y este es ¡sálvese quien pueda! Pero persiste la esperanza en la escuela y en sus maestros.

Full Text Available Existen múltiples factores que impactan la manera como los maestros principiantes perciben y viven el primer año de experiencia docente. La incorporación y acogida en el centro escolar está mediada por la percepción del maestro acerca del tipo de acogida en el nuevo contexto de trabajo, en especial el apoyo de los pares y la dirección, y la madurez profesional. Este artículo presenta una investigación sobre el primer año de experiencia docente en centros públicos de infantil y primaria de Catalunya. El estudio ha previsto la realización de estudios de caso en cinco centros educativos de distintas características. Para cada estudio de caso se han realizado entrevistas individuales y grupales a maestros principiantes, a los tutores de los principiantes y a los equipos directivos. También se han llevado a cabo grupos de discusión con los formadores y principiantes del curso de iniciación a la docencia promovido por la Generalitat de Catalunya y entrevistas a distintos servicios de educación (inspección, equipos psicopedagógico y centros de recursos. Finalmente se han realizado y analizado documentos videográficos y textuales (observaciones de prácticas docentes de profesores principiantes y planes de acogida de distintos centros. Los resultados que aquí se presenta resumen una parte del estudio, esto es las percepciones de maestros, tutores y directivos, y confirman la necesidad de ofrecer una formación para la inducción a los profesores de primer año que contemple la reflexión sobre la realidad diaria en base a casos prácticos, así como planificar la acogida mediante un plan contextualizado que observe tanto la información necesaria sobre el centro como las estrategias de acompañamiento e inducción a la práctica docente por parte de profesores más expertos y el rol del equipo directivo.

Las conclusiones de la investigación han permitido reformular contenidos y orientaciones de la formación inicial, así como establecer las necesidades de formación permanente consideradas por los propios maestros en función de su práctica docente.
FORMATO ESCUELA VS MAESTRO INVESTIGADOR

2016-08-01

Full Text Available Colombia asume la investigación en la Educación Básica como una estrategia privilegiada para mejorar la calidad de la educación. Con base en una experiencia de formación de docentes, el artículo plantea una hipótesis contraria: la figura del maestro investigador es incompatible con la escuela. La hipótesis se soporta en la categoría Formato Escuela, es decir, la escuela tiene una forma histórica en la cual la investigación, en su modelo científico-universitario, no tiene posibilidad de realización porque es incompatible con ella. Más aún, maestro investigador es una abstracción construida a espaldas de la escuela y, por tanto, no es por la vía de invocaciones, de enjuiciamientos y ni siquiera por la misma formación de los maestros en investigación que se hará realidad esta figura ilusoria; se requiere, mejor, actuar por vías políticas y legales sobre el formato para convertir a la escuela en investigadora, y, una vez lo sea, ella misma convertirá en investigadores a los maestros; el camino inverso, intentar convertir a los maestros en investigadores para que transformen la escuela, será la crónica de un fracaso educativo anunciado, o la suma de propuestas sin más impacto que los objetivos de su propia ejecución.
Extreme Programming: Maestro Style

Science.gov (United States)

Norris, Jeffrey; Fox, Jason; Rabe, Kenneth; Shu, I-Hsiang; Powell, Mark

2009-01-01

"Extreme Programming: Maestro Style" is the name of a computer programming methodology that has evolved as a custom version of a methodology, called extreme programming that has been practiced in the software industry since the late 1990s. The name of this version reflects its origin in the work of the Maestro team at NASA's Jet Propulsion Laboratory that develops software for Mars exploration missions. Extreme programming is oriented toward agile development of software resting on values of simplicity, communication, testing, and aggressiveness. Extreme programming involves use of methods of rapidly building and disseminating institutional knowledge among members of a computer-programming team to give all the members a shared view that matches the view of the customers for whom the software system is to be developed. Extreme programming includes frequent planning by programmers in collaboration with customers, continually examining and rewriting code in striving for the simplest workable software designs, a system metaphor (basically, an abstraction of the system that provides easy-to-remember software-naming conventions and insight into the architecture of the system), programmers working in pairs, adherence to a set of coding standards, collaboration of customers and programmers, frequent verbal communication, frequent releases of software in small increments of development, repeated testing of the developmental software by both programmers and customers, and continuous interaction between the team and the customers. The environment in which the Maestro team works requires the team to quickly adapt to changing needs of its customers. In addition, the team cannot afford to accept unnecessary development risk. Extreme programming enables the Maestro team to remain agile and provide high-quality software and service to its customers. However, several factors in the Maestro environment have made it necessary to modify some of the conventional extreme

Full Text Available En este trabajo se analizan los resultados de aprendizaje respecto a las ciencias, que alcanzan los futuros maestros y maestras de educación infantil cuando preparan unidades didácticas. Para ello, se ha construido un instrumento de análisis a partir de los resultados de aprendizaje que cabría esperar teniendo en cuenta las competencias que, para nuestra área de conocimiento, aparecen en la memoria de título de Grado de Maestro/a en Educación Infantil de la Universidad de Valencia. Tres investigadores independientes, haciendo uso de dicho instrumento, han analizado 19 unidades didácticas elaboradas por 76 alumnos del 4º curso durante dos cursos académicos consecutivos, cuando cursan la materia propia de Didáctica de las Ciencias. Los resultados ponen de manifiesto que, según aumenta la especificidad de los resultados de aprendizaje en el área de didáctica de las ciencias, menos consolidados están, lo que plantea una necesaria revisión tanto de los contenidos didácticos planteados, como de su desarrollo en los planes de estudio universitarios, con el fin de mejorar la formación inicial de maestros de educación infantil en el ámbito de la enseñanza de las ciencias.

El que sus interacciones cotidianas se desarrollen en un contexto caracterizado por el miedo generado por las vivencias de acciones de guerra como combates, masacres, señalamientos y amenazas, además marcadas por la impunidad, la no reparación y la percepción de indefensión, hace que la identidad del maestro, que está constituida por su propia historia personal, por la conciencia de su rol público, por la valoración social de su profesión, y por su definición política, producen diferentes formas de enunciación de sí mismos, a la vez que determinantes del tipo de actitud que se asuma como mecanismo de sobrevivencia.

Full Text Available RESUMEN: «¡Ay, de la escuela donde el pobre maestro cuenta impaciente en el reloj los minutos que aún faltan para dar terminada la clase! Y, con efecto, en esta disposición de su ánimo muestra el desaliento de sus antiguas esperanzas; la sombría perspectiva de su porvenir; el desamor hacia una profesión que tal vez alcanzara con anhelo, y el desabrido afán por vender su vana primogenitura a cambio de cualquier otra ocupación que le libere de aquella monotonía, cercana a la esclavitud y verdaderamente valiosa». F. Giner, autor de la cita anterior, culpabiliza de esta situación a la falta de medios, de preparación, de dirección pedagógica y al desinterés por parte del gobierno y de la sociedad en general, que son quienes han permitido el aislamiento, la miseria y el desamparo del maestro. Coincidimos plenamente con la argumentación anterior, pero pensamos que donde más se nota la falta de estimación hacia el magisterio es en su bajo nivel retributivo, problema que ha quedado patente a lo largo del presente estudio.

Full Text Available Las iniciativas 1:1 han hecho posible que cerca de un millón de computadoras portátiles hayan sido distribuidas a niños en todo el Perú con propósitos educativos. A pesar de lo significativo de las inversiones, las más de novecientas mil computadoras personales que distribuyó el gobierno desde 2007 entre niños de educación básica no han mejorado hasta ahora la calidad de la educación peruana —principal objetivo del programa—. Con este trabajo, pretendemos brindar elementos que permitan una aproximación a la cotidianidad de la actividad educativa en el campo, con relación a los motivos por los que los maestros no usan las computadoras portátiles, así como una mejor comprensión sobre lo que está sucediendo en las aulas. La investigación inicia con un marco conceptual a partir de la revisión de trabajos teóricos; le sigue la revisión de algunas experiencias internacionales, incluyendo una descripción del programa "Una laptop por niño". El estudio de los datos comprendió la categorización de la información recogida mediante el análisis de contenido. Concluimos con la discusión de una serie de elementos que impiden que los maestros usen las computadoras portátiles.

Antecedentes históricos del proceso de formación permanente del maestro tutor y su sistematización

MSc. Nirma Pérez-Pelipiche

2016-02-01

Full Text Available El estudio histórico realizado permitió evidenciar que la formación permanente de los maestros tutores de los estudiantes de Licenciatura en Educación Primaria ha transitado desde de una concepción espontánea, ocasional y a veces improvisada, hacia una más organizada en la que se han asumido posiciones de constantes cambios a favor del proceso formativo universitario pedagógico. Sin embargo, aún persisten restricciones epistemológicas y praxiológicas que limitan su efectividad, siendo notorio en el contexto de la microuniversidad durante la práctica laboral de los estudiantes en formación. Los estudios revelan que si bien el maestro tutor se erige en una figura esencial del proceso formativo pedagógico, no siempre su preparación ha sido efectiva, por lo que se requiere de una dinámica contextualizada de formación permanente que propicie nuevos sistemas de relaciones, vías y actitudes que actualicen y renueven las formas de ejercer sus funciones formativas en correspondencia con la realidad educativa contemporánea.

Full Text Available Este artículo describe el proceso de investigación desarrollado para la elaboración del sentido social de la idea de un buen maestro, por parte de un grupo de niñas y niños, madres y padres de familia, y profesores y profesoras de las carreras de Educación de las universidades estatales costarricenses. Con la aplicación de un enfoque cualitativo en el que se utilizó la estrategia de análisis de contenido mediante la técnica de análisis de contingencias, se le dio respuesta al siguiente problema de investigación: ¿Cuál es la correspondencia teórica entre el sentido social de la idea del buen maestroy los enfoques normativo y descriptivo para la formación inicial de educadores? Desde el punto de vista del enfoque normativo de formación de educadores, las características que mayormente se destacan son: tiene personalidad de maestro, tiene destrezas de maestro y practica conductas de maestro. En concordancia con el enfoque descriptivo de formación de educadores, las características que se destacan son las siguientes: desarrolla y aplica estrategias de pensamiento, desarrolla y aplica estrategias de percepción u observación, desarrolla su capacidad para la toma de decisiones, sabe considerar el contexto y puede individualizar su tarea. Se concluye que persisten percepciones en el grupo de participantes que elaboran un imaginario del maestro ideal tanto desde la perspectiva normativa como la descriptiva. En el caso de las percepciones basadas en el enfoque normativo, éstas ocasionan un sentimiento de inadecuación para la tarea docente por parte de estos profesionales, con sus consecuencias negativas.

Full Text Available El contenido que ofrecemos en este artículo hace referencia a la dimensión vocacional de los aspirantes a maestro. Tradicionalmente, la enseñanza se ha considerado como una profesión genuinamente vocacional; una circunstancia que, sin embargo, no siempre le ha favorecido. En estos momentos, a pesar de las dificultades que rodean la tarea docente, existe un alto número de estudian-tes que optan por la enseñanza y acceden a las Escuelas de Magisterio. Real-mente, nos podríamos preguntar si el docente -nace o se hace- vocacional hacia esta actividad profesional. Aportamos para ello, los datos de una investigación realizada entre estu-diantes de la Universidad de Sevilla, donde se viene a demostrar por un lado que, muchos eligieron la carrera sin tener un verdadero interés por ella; y por otro, que las Escuelas de Magisterio son en muchos casos, un motor esencial para llegar a despertar o, a descubrir entre los estudiantes, su verdadero interés e inclinación por la enseñanza. Posiblemente, desarrollar actitudes vocaciona-les entre tos aspirantes a maestro es, también, una labor implícita de la Forma-ción Inicial de Maestros
MAESTRO, a hydraulic manipulator for maintenance and decommissioning applications

2006-01-01

Compared to electric technology payload of hydraulic manipulators is very high with respect to their volume and mass. However, due to their force control limitations they were usually disqualified for precise manipulation. CEA, in collaboration with CYBERNETIX developed a complete remote handling system around the advanced hydraulic robotic arm MAESTRO. Requirements and specifications of the system were defined according to the needs of decommissioning activities in existing nuclear facilities and maintenance scenarios of the next step fusion reactor ITER. Using TAO2000 CEA controller, CEA developed specific force control loops to improve the performances of the manipulator and reach a level where the MAESTRO can be used like a traditional tele-operation master/slave system with force feedback. The complete system is composed of a 2 m long 100 kg payload 6 degrees of freedom slave hydraulic manipulator. The manipulator is mounted on an embedded unit made of a 210 bars hydraulic power pack and a 10 kGy rad hardened slave controller. The master station is made of the new generation Virtuose V6D-40-40 master arm with its TAO2000 controller. The graphical supervisor Magritte gives the operator an additional interface to manage and monitor the system. Repetitive tasks like tool picking can therefore be left to the system while the operator keeps his concentration on the main task. Thanks to the collision detection algorithm, Magritte warns the operator when the tool or any part of the Maestro arm comes too close to a delicate unit. Operational experience gained through test campaigns was gathered in an upgrade study to propose a new version of the manipulator that successfully ran through a 1000 hour endurance test. Rad-hardened components were selected and tested in nuclear facilities. Attention was paid to provide a design in which contamination is easily removed and to ease the maintenance when performed by an operator in suit. To be quickly adapted to new tasks, the

Bayuelo, Ezequiel

Este estudio examino y comparo las actitudes de los candidatos a maestros de ciencias y los maestros de ciencias en servicio acerca de la utilizacion de las herramientas computadorizadas en las clases de ciencias. Tambien identifico y diferencio el uso que ellos dan a estas herramientas en las clases de ciencias. Este estudio presenta un diseno descriptivo exploratorio. Constituyeron la muestra trescientos diez sujetos que fueron candidatos a maestros de ciencias o maestros de ciencias en servicio. Para recoger los datos se construyo y valido un cuestionario de treinta y un itemes. Se utilizaron las pruebas estadisticas no parametricas Kruskal Wallis y Chi-cuadrado (test de homogeneidad) para establecer las diferencias entre las actitudes de los sujetos con relacion al uso de las herramientas computadorizadas en las clases de ciencias. Los hallazgos evidenciaron que son positivas y muy parecidas las actitudes de los candidatos a maestros y maestros en servicio hacia el uso de las herramientas computadorizadas. No hubo diferencias entre los candidatos y maestros en servicio en terminos de las actitudes de confianza y empatia hacia el uso de las herramientas computadorizadas en las clases de ciencias. En aspectos como el uso del banco de datos bibliografico Eric y el uso de las herramientas computadorizadas en actividades educativas como explorar conceptos, conceptuar, aplicar lo aprendido y hacer asignaciones hubo diferencias estadisticamente significativas entre los candidatos y los maestros en servicio. Al comparar las frecuencias observadas con las esperadas hubo mas maestros en servicio y menos candidatos que indicaron usar el anterior banco de datos y las herramientas computadorizadas en las mencionadas actividades educativas.

Full Text Available Para lograr una educación de excelencia que lleve a formar a los profesionales del siglo XXI, es necesario fortalecer la cultura de superación y evaluación del proceso educativo por medio de instrumentos y mecanismos que permitan retroalimentar la calidad de este proceso; uno de ellos es a través de la caracterización de la práctica profesional, la cual es definida como la aplicación concreta y autónoma de una profesión, en un lugar, tiempo y circunstancias determinadas. En este sentido, corresponde un papel central a la educación, ya que los profesionistas formados en las instituciones de enseñanza superior tienen que demostrar sus capacidades, conocimientos, habilidades y responsabilidades en el ejercicio profesional, compitiendo en un espacio laboral inestable. El enfoque de la presente investigación fue cuantitativo, con la intención de detectar el impacto que han tenido los egresados de la Maestría en Educación Superior de la Benemérita Universidad Autónoma de Puebla. Este trabajo permitió obtener información significativa y relevante que conlleva a fortalecer el vínculo práctica profesional-formación profesional, lo que permitirá tener parámetros significativos para adecuar el plan de estudio que actualmente se desarrolla en la formación de Maestros en Educación Superior.

Full Text Available El propósito de este estudio fue identificar los niveles de adquisición de las competencias digitales de los docentes de las preparatorias incorporadas al Instituto Tecnológico de Sonora (ITSON, a fin de obtener un diagnóstico que permita planear un programa de estrategias de formación en el área de tecnología aplicadas en la educación; lo anterior, debido a que no hay estudios que ayuden a precisar en qué aspectos se necesita capacitar a los maestros de dichas escuelas. La investigación fue descriptiva con enfoque cuantitativo y un diseño no experimental transeccional. Participaron 170 maestros, a quienes se les administró una encuesta compuesta por 47 reactivos que medían cinco dimensiones: conocimientos y habilidades en la Web, organización en formato digital, uso de herramientas o dispositivos digitales para la comunicación, búsqueda electrónica y diseño de recursos educativos digitales. Los resultados revelan que gran parte de los maestros poseen mayor dominio en la dimensión de organización en formato digital y la que menos dominan y en la requieren un curso de capacitación es en la de diseño de recursos educativos digitales. Asimismo, a mayor edad y a más años de servicio, los maestros tienden a hacer un menor uso de la tecnología, por lo que manifiestan un menor dominio de las competencias digitales.

Concepciones y concepciones alternativas de estudiantes universitarios/as de biologia y futuros maestros/as de Ciencia de escuela secundaria sobre la teoria de evolucion biologica por seleccion natural

Morales Ramos, Egda M.

La teoria de evolucion biologica (TEB) por seleccion natural es uno de los conceptos unificadores mas importantes del curriculo de Biologia. En Puerto Rico se han hecho pocas investigaciones que abunden sobre las concepciones y concepciones alternativas (CA) que tienen los estudiantes universitarios/as de Biologia y los maestros/as de Ciencia del nivel secundario sobre esta teoria. La politica publica educativa actual establece mediante documentos normativos como los Estandares de contenido y Expectativas de grado del Programa de Ciencias [Puerto Rico Core Standards] la ensenanza de esta teoria. Sin embargo, no se encontraron preguntas sobre la seleccion natural en los ejercicios de practica provistos por el Departamento de Educacion para las pruebas estandarizadas lo cual puede influir para que no se ensene adecuadamente. Las preguntas de investigacion fueron 1. ¿Cuales son las concepciones y concepciones alternativas de estudiantes universitarios/as y de los futuros maestros y maestras de Ciencia sobre la TEB? 2. ¿Cuales conceptos que seleccionan los estudiantes universitarios/as y los futuros maestros y maestras de Ciencia sobre la TEB coinciden con lo aceptado como valido por la comunidad cientifica? y 3. ¿Como comparan las respuestas de la prueba original. v. Entendiendo el cambio biologico que mide concepciones y CA sobre la TEB por seleccion natural, con las de la traducida al idioma espanol? Se utilizo el metodo cuantitativo con un diseno de investigacion transversal por encuesta. La tecnica principal para recopilar los datos fue una prueba con doce items, que formo parte de un instrumento para el cual se recopilaron diversas fuentes de evidencia acerca de su validez. Las muestras estuvieron formadas por 69 estudiantes de Ciencias Naturales y por 16 estudiantes futuros maestros y maestras del nivel secundario de la UPR-RP.

Full Text Available RESUMEN: La historia de los planes de estudio para la formación del maestro es la historia del paso de lo cultural a lo profesional, expresado en la pérdida o ganancia de la formación cultural o de la formación profesional. Asimismo, la organización de las Prácticas de Enseñanza ha experimentado diferentes momentos en función de la importancia que estos planes han concedido a su desarrollo. Los sistemas educativos, la Universidad, los expertos en formación de formadores tienen que tender a conseguir un maestro, un docente. La proyección de las Escuelas Normales en el contexto socio-político y cultural resulta significativa. Analizar los diferentes planes de formación es analizar la trayectoria educativa de un pueblo que se plantea su futuro desde las materias culturales o profesionales pero siempre bajo los perímetros de la superación pedagógica.ABSTRACT: The history of the curriculum in teacher training is the history of a move from the cultural sphere to the professional sphere, expressed in the loss or gain of cultural training or professional training. Thus, the organization of teaching practice has gone through different stages according to the importance afforded it by these different curricula. Educational systems, the University and experts in the forming of teachers all have to look towards producing a teacher, an educator. The influence of Teacher Training Schools on the socio-political and cultural context is significant. To analyse the different curricula in teacher training is to analyse the trajectory of education within the perimeter of educational improvement.

Full Text Available Este artículo describe el proceso de investigación desarrollado para la elaboración del sentido social de la idea de un buen maestro, por parte de un grupo de niñas y niños, madres y padres de familia, y profesores y profesoras de las carreras de Educación de las universidades estatales costarricenses. Con la aplicación de un enfoque cualitativo en el que se utilizó la estrategia de análisis de contenido mediante la técnica de análisis de contingencias, se le dio respuesta al siguiente problema de investigación: ¿Cuál es la correspondencia teórica entre el sentido social de la idea del “buen maestro”y los enfoques normativo y descriptivo para la formación inicial de educadores? Desde el punto de vista del enfoque normativo de formación de educadores, las características que mayormente se destacan son: tiene personalidad de maestro, tiene destrezas de maestro y practica conductas de maestro. En concordancia con el enfoque descriptivo de formación de educadores, las características que se destacan son las siguientes: desarrolla y aplica estrategias de pensamiento, desarrolla y aplica estrategias de percepción u observación, desarrolla su capacidad para la toma de decisiones, sabe considerar el contexto y puede individualizar su tarea. Se concluye que persisten percepciones en el grupo de participantes que elaboran un imaginario del maestro ideal tanto desde la perspectiva normativa como la descriptiva. En el caso de las percepciones basadas en el enfoque normativo, éstas ocasionan un sentimiento de inadecuación para la tarea docente por parte de estos profesionales, con sus consecuencias negativas. This article describes the research process applied to identify the social sense of the idea of a good teacher, as viewed by a group of children, parents and university professors from state universities of Costa Rica .

2014-10-23

The Missouri Agricultural Energy Saving Team-A Revolutionary Opportunity (MAESTRO) program brought together a team of representatives from government, academia, and private industry to enhance the availability of energy efficiency services for small livestock producers in the State of Missouri. The Missouri Department of Agriculture (MDA) managed the project via a subcontract with the University of Missouri (MU), College of Agriculture Food and Natural Resources, MU Extension, the MU College of Human Environmental Sciences, the MU College of Engineering, and the Missouri Agricultural and Small Business Development Authority (MASBDA). MU teamed with EnSave, Inc, a nationally-recognized expert in agricultural energy efficiency to assist with marketing, outreach, provision of farm energy audits and customer service. MU also teamed with independent home contractors to facilitate energy audits of the farm buildings and homes of these livestock producers. The goals of the project were to: (1) improve the environment by reducing fossil fuel emissions and reducing the total energy used on small animal farms; (2) stimulate the economy of local and regional communities by creating or retaining jobs; and (3) improve the profitability of Missouri livestock producers by reducing their energy expenditures. Historically, Missouri scientists/engineers conducted programs on energy use in agriculture, such as in equipment, grain handling and tillage practices. The MAESTRO program was the first to focus strictly on energy efficiency associated with livestock production systems in Missouri and to investigate the applicability and potential of addressing energy efficiency in animal production from a building efficiency perspective. A. Project Objectives The goal of the MAESTRO program was to strengthen the financial viability and environmental soundness of Missouri's small animal farms by helping them implement energy efficient technologies for the production facility, farm

Cardona Tomassini, Ivan Javier

En esta investigacion se estudio el fenomeno del conocimiento de contenido y el conocimiento curricular de maestros de matermaticas y como estos dos componentes se reflejan en su conocimiento pedagogico del contenido. El conocimiento de contenido es el conocimiento que tienen los maestros de los contenidos de una disciplina y sobre la estructura de su organizacion (Shulman, 1986). El conocimiento curricular es el conocimiento que los maestros poseen sobre los componentes de un curriculo disenado para ensenar un topico de una materia especifica a un nivel particular, la variedad de instrumentos instruccionales disponibles para implementar el mismo y como utilizar los instrumentos curriculares disponibles (Ball & Bass, 2003; Choppin, 2009; Hill, Rowan, & Ball, 2005). Este estudio se enmarca en el paradigma cualitativo, teniendo como diseno el estudio fenomenologico (Lucca y Berrios, 2009; McMillan, 2004). Los participantes fueron seis maestros de matermaticas del nivel superior (10mo a 12mo grado). Al momento de la investigacion los participantes ensenaban en escuelas publicas o privadas de Puerto Rico. Para recolectar la informacion se utilizo un grupo focal en donde los maestros resolvieron seis ejercicios matematicos y posteriormente reflexionaron en forma grupal sobre las soluciones. Tambien se realizo un analisis de documentos de planificacion y se llevaron a cabo entrevistas semiestructuradas. Se exploraron los contenidos relacionados a la ecuacion de una recta, rectas verticales y horizontales, suma y multiplicacion de polinomios, resolucion de ecuaciones cuadraticas y distancia entre dos puntos del plano cartesiano. Los resultados muestran que los participantes tienen dominio procesal de los contenidos correspondientes a las rectas verticales y horizontales, la suma y multiplicacion de polinomios, el calculo distancia entre dos puntos del plano cartesiano.

Full Text Available El artículo examina el lento proceso de profesionalización de los maestros de la escuela elemental, desde la realidad educativa fragmentada del Antiguo Régimen hasta el surgimiento de un cuerpo docente con una preparación específica y una identidad colectiva. El Estado italiano tuvo un papel relevante en este proceso, pues se preocupó de la recualificación de los maestros y de preparar a los nuevos estudiantes a la altura de la exigente tarea de combatir el alto nivel de analfabetismo y favorecer la adhesión del pueblo a los nuevos valores en los que el Estado se fundaba. La profesión quedó poco remunerada y precaria y por este motivo acogió numerosas mujeres, las cuales encontraban una ocupación digna y considerada adecuada a la naturaleza femenina; aunque la llegada de chicas jóvenes solas a pequeños pueblos resultó a veces en persecuciones que encontraron eco en la prensa y la literatura. La mejora del nivel cultural de los maestros hizo insostenible la contradicción entre la exaltación retórica del rol del maestro y las condiciones reales de la profesión, favoreciendo la maduración de una conciencia de clase, lo cual contribuyó también en la prensa pedagógica. En el nuevo siglo se desarrolló un asociacionismo cada vez más combativa que obtuvo resultados significativos, pero que vio socavada por las profundas divisiones internas entre maestros y maestras, maestros rurales y urbanos, católicos y laicos. Acusados de defender intereses corporativos y de no atender a las necesidades de la escuela, los maestros fueron llamados al orden en la reforma Gentile, uno de los primeros actos del fascismo en el poder.

El maestro es acción de este lenguaje movido por el historial social y cultural que permite hacer de la escritura un oficio ético y estético donde la mano construye y nombra las emociones que atraviesan al cuerpo. La escritura es el testimonio vital del maestro como artesano; es el arte del lenguaje que sale de su silencio con la lectura del relato, pero es, además, la potencia del pensamiento puesto en pretexto estético donde se pregunta y se reflexiona por el tiempo y por el espacio de la palabra, es decir, las cronologías, kairologías, territorialidades y escenarios de las esferas educativas. Sobre estos presupuestos se propone una discusión pedagógica en torno a la necesidad de pensar la escritura artesanal como intención estética y política donde se plasma el testimonio del compromiso ético del maestro, pero también la perspectiva de los nuevos retos que la educación debe asumir para reencontrar el lenguaje con la vida y con las herencias socioculturales que dan cuenta del sujeto y de las subjetividades que confluyen en los procesos de formación, y que tienen despliegue y búsqueda en el escenario creativo y productivo de la escritura. Se intentará, entonces, reivindicar una pedagogía de la posibilidad en el lenguaje, una narratividad donde la memoria traza un puente para el encuentro de épocas, de rostros, de acontecimientos, de silencios y de saberes, donde el maestro está llamado a tejer, tallar, dibujar, componer y comunicar las artesanías que la educación ha olvidado, es decir, recuperar la memoria estética, lo cual también implica un olvido de las formas hegemónicas del arte.

Una educación desde la cuna hasta la tumba inconforme y reflexiva, que nos inspire un nuevo modo de pensar y nos incite a descubrir quiénes somos en una sociedad que se quiera más a sí misma. Que aproveche al máximo nuestra creatividad inagotable y conciba una ética y tal vez una estética para nuestro afán desaforado y legítimo de superación personal. Que integre la ciencia y las artes a la canasta familiar, de acuerdo a los designios de un gran poeta de nuestro tiempo que pidió no seguir amándoles por separadas como a dos hermanas enemigas. Que canalice hacia la vida, la inmensa energía creativa, que durante siglos hemos despilfarrado en la depredación y la violencia y nos abra al fin la segunda oportunidad sobre la tierra que no tuvo la estirpe desgraciada del Coronel Aureliano Buendía; por el país próspero y justo que soñamos: Al alcance de los niños".

Full Text Available Este trabajo surge de una preocupación derivada de mi práctica en la formación del profesorado. Tiene como fin averiguar la problemática que genera el proceso de enseñanza-aprendizaje del canto en un maestro varón dentro del ámbito de la enseñanza general. Pretende, además, ubicar y comprender dicha problemática en su contexto. No sólo viene a paliar la ausencia de investigación al respecto, sino también a abrir cauces para el desarrollo de didácticas específicas basadas en la investigación que puedan repercutir fructíferamente en las escuelas. Como estrategia de indagación utilicé el estudio de casos, empleando técnicas de recogida de datos asociadas con la metodología cualitativa. El análisis y la interpretación de los datos revelan que el perfil del maestro es determinante y que tiene gran incidencia en la práctica vocal de aula al poner de manifiesto las interacciones entre la formación vocal del maestro, el modelo vocal que ofrece y la práctica de aula. La cuestión de género plantea una problemática vocal específica con implicaciones relevantes. Además, de este estudio derivan sugerencias significativas relacionadas con la formación vocal de los maestros.

Compared to electric manipulators, hydraulic manipulators can handle higher payloads with respect to their size and mass. However, due to their limited positioning resolution and dexterity, they are usually disqualified for precise tele-manipulation and high quality tele-operation. More over, experience feedback has shown that on-the-shelf hydraulic manipulators are not reliable when performing high demanding tasks in tele-operation for dismantling applications. In order to solve this problem, CEA (Commissariat l'Energie Atomique), in collaboration with Cybernetix company, has developed a computer-aided, high-precision remote handling system with force-feedback featuring the advanced hydraulic tele-robotic arm Maestro.

Transforming han: a correlational method for psychology and religion.

Science.gov (United States)

Oh, Whachul

2015-06-01

Han is a destructive feeling in Korea. Although Korea accomplished significant exterior growth, Korean society is still experiencing the dark aspects of transforming han as evidenced by having the highest suicide rate in Asia. Some reasons for this may be the fragmentation between North and South Korea. If we can transform han then it can become constructive. I was challenged to think of possibilities for transforming han internally; this brings me to the correlational method through psychological and religious interpretation. This study is to challenge and encourage many han-ridden people in Korean society. Through the psychological and religious understanding of han, people suffering can positively transform their han. They can relate to han more subjectively, and this means the han-ridden psyche has an innate sacredness of potential to transform.

Full Text Available La formación de maestros de lenguas extranjeras en Estados Unidos es un tema muy tratado y que ha ganado mucha popularidad en los últimos años dentro de la nación. El empuje por cuantificar el uso de prácticas efectivas ha intensificado el enfoque en estándares y métodos de enseñanza, muchas veces obviando la importancia de la aptitud lingüística que tienen los docentes en el idioma que enseñan. El presente artículo expone realidades sobre la disímil formación de maestros de idiomas de preescolar (K a duodécimo grado (12 grado en Estados Unidos. Para esto, el autor elucida el contexto de formación docente de maestros de idiomas y los requisitos para enseñar lenguas extranjeras en las escuelas públicas primarias y secundarias de la nación. Además, el artículo expone retos asociados a las prácticas de la formación docente actual y sus implicaciones tanto para educadores como para estudiantes. Asimismo, el autor concluye con interrogantes sobre el futuro de la formación docente en Estados Unidos durante un período donde se acrecienta la demanda por el aprendizaje de lenguas extranjeras mientras la nación experimenta un declive de profesores de idiomas.

Una escultura de alabastro producida en los talleres del maestro de Rímini: la Vírgen de la Peña, en Betancuria (Fuerteventura

Full Text Available During the first decades of the 15th century excellent alabaster sculptures were produced in highly active European workshops located in the frontier region between northern France and the southern Low Countries, in a geographical area comprised by the cities of Lille, Arras and Tournai, and in the lower and middle Rhine. They were small-scale pieces appropriate for distribution to a wide market thanks to continuous mercantile activities. In these workshops sculptures with very similar characteristics were carried out which have been attributed to the so-called “Master of Rimini.” One of the most frequent types was the “Virgin Seated with the Christ Child,” adapted to the International Gothic or “beautiful style” between 1400 and 1440. The Virgin of the Rock in the Sanctuary of Betancuria (Fuerteventura Island, Canaries, corresponds to the prolific workshops of the “Master of Rimini.”

En las primeras décadas del siglo XV fueron ejecutadas excelentes esculturas de alabastro en talleres europeos de gran producción, localizados en una zona fronteriza entre el norte de Francia y el sur de los antiguos Países Bajos meridionales, en un área geográfica comprendida entre las ciudades de Lille, Arras y Tournai, y en el bajo y medio Rin. Eran piezas de reducido formato que fueron distribuidas en un amplio mercado gracias a la incesante actividad mercantil. En estos talleres fueron elaboradas obras con características muy afines entre ellas, que han sido adscritas al arcano “Maestro de Rímini”. Una de las tipologías de mayor tratamiento fue la “Virgen sedente con Niño”, de gran arraigo en la iconografía mariológica, que fue adaptada a una de las variantes del Gótico Internacional, al denominado “estilo suave” o “bello estilo”, desarrollado entre 1400 y 1440, aunque con ligeros matices diferenciales.

La relevancia encubierta del género: las percepciones de los futuros maestros sobre la igualdad y las desigualdades contextuales

Gladys Merma Molina

2015-12-01

Full Text Available Este artículo indaga sobre las percepciones y las actitudes de los estudiantes, futuros maestros de Educación Infantil, sobre la igualdad de oportunidades de género. Para ello se han planteado las siguientes cuestiones de investigación: ¿Cuál es la visión de los alumnos sobre la igualdad de oportunidades de género? y ¿Qué vivencias relacionadas con la discriminación de género dentro y fuera del ámbito universitario manifiestan haber experimentado los estudiantes? La metodología cualitativa, utilizada en la investigación, nos ha permitido analizar el pensamiento del alumnado a través de sus propias voces. Los resultados del estudio muestran que los estudiantes son conscientes de la importancia de la igualdad; no obstante, denuncian la persistencia de creencias estereotipadas y disparidades especialmente fuera de la universidad. Aun así, sus expectativas son positivas y apuestan por avanzar en la igualdad de oportunidades fundamentalmente en la formación académica y en el desempeño profesional. Aunque en ocasiones existen ciertas incongruencias entre cómo piensan y actúan, muestran una postura favorable hacia la equidad. Este estudio pone en evidencia que es importante desarrollar acciones concretas y formales en la docencia universitaria, ya que una legislación favorable no es suficiente para construir una auténtica cultura de género.
Nuevos hallazgos documentales y biográficos sobre Alonso Xuárez maestro de Sebastián Durón

Directory of Open Access Journals (Sweden)

de la Fuente Charfolé, José Luis

2012-12-01

Full Text Available Alonso Xuárez was no minor composer in the musical field of his time. The quality and effectiveness of his compositions makes them deserving of a leading place in Spanish and European music of the 17^th century. In spite of this almost nothing is known about this composer prior to his being appointed to teach in the chapel of Cuenca cathedral. Virtually all the currently available data is of a secondary and collateral nature and arises from research into his disciple the organist Sebastián Durón, the renowned opera composer and teacher at the Capilla Real of Charles II.

Alonso Xuárez no fue un compositor menor dentro del panorama musical de su tiempo. La calidad y eficacia de su música merece estar en primera línea de la música española y europea del siglo XVII. Sin embargo, el desconocimiento de este músico es casi completo con anterioridad a su nombramiento en el magisterio de capilla de la catedral de Cuenca. Prácticamente todos los datos expuestos hasta el momento han sido restos secundarios y colaterales desprendidos de otras investigaciones realizadas sobre la figura de su discípulo, el reputado compositor de teatro lírico y maestro de la Capilla Real de Carlos II, el organista Sebastián Durón.

1945-2003 Hans Sann, an internationally recognized scientist, beloved colleague and friend, died in a tragic car accident, on May 27th, on one of his many travels to CERN. Employed at GSI, in Darmstadt, since 1979, Hans Sann devoted most of his scientific career to the development of large size gas detectors for nuclear and high-energy physics experiments at GSI, CERN and Berkeley. One of his main achievements, among many others, was the famous MUSIC detector, on which several projects at GSI, Berkeley and other research Institutes were based. The innovative results obtained in the study of the fluid-gas transition in nuclear matter would not have been possible without his contribution and the application of the MUSIC detector. A member of the ALICE Collaboration since 1996, Hans was leading two main ALICE sub-programmes, the development of the gas system and the cooling system for the TPC detector. In addition, he was involved in the development of a new technological concept for the resistor chain of the ...

Se busca mostrar los elementos comprensivos de los que puede disponer el maestro para ofrecer a los niños posibilidades de transformar las experiencias de juegos estereotipados, llamados juego -juguete-, en juego simbólico. La observación y análisis de las actividades de los niños muestra cómo ellos organizan nuevas representaciones a partir de los nuevos significados que otorgan a sus experiencias. Frente a estos procesos de los niños, el maestro tiene un rol primordial para favorecer las experiencias de significación que sustentan los procesos de aprendizaje

Full Text Available La nueva reforma de los planes de estudios, impulsada por la adaptación al EEES, constituye una oportunidad para reflexionar sobre los contenidos y las metodologías empleadas hasta este momento en los títulos de maestro pero, además, en relación con la educación inclusiva, supone cambiar la concepción deficitaria que subyacía en la mayoría de las asignaturas que los preparaban, dotando a los futuros maestros de la perspectiva de la inclusión y abordando los cambios necesarios para dar respuesta a todos los alumnos. En este artículo hacemos un análisis de las necesidades formativas de los futuros maestros para atender a la diversidad e intentamos determinar los cambios en los nuevos planes, para establecer si los mismos darán respuesta a las demandas de una escuela inclusiva.

Many of propellants that are applied to the conventional spacecraft propulsion system are toxic propellants. Because of its toxicity, considering the environmental pollution or safety on handling, it will be necessary to apply the "green" propellant to the spacecraft propulsion system. The purpose of this study is to apply HAN based liquid propellant (LP1846) to mono propellant thruster. Compared to the hydrazine that is used in conventional mono propellant thruster, HAN based propellant is not only lower toxic but also can obtain higher specific impulse. Moreover, HAN based propellant can be decomposed by the catalyst. It means there are the possibility of applying to the mono propellant thruster that can leads to the high reliability of the propulsion system.[1],[2] However, there are two technical subjects, to apply HAN based propellant to the mono propellant thruster. One is the high combustion temperature. The catalyst will be damaged under high temperature condition. The other is the low catalytic activity. It is the serious problem on application of HAN based propellant to the mono propellant thruster that is used for attitude control of spacecraft. To improve the catalytic activity of HAN based propellant, it is necessary to screen the best catalyst for HAN based propellant. The adsorption analysis is conducted by Monte Carlo Simulation to screen the catalyst metal for HAN and TEAN. The result of analysis shows the Iridium is the best catalyst metal for HAN and TEAN. Iridium is the catalyst metal that is used at conventional mono propellant thruster catalyst Shell405. Then, to confirm the result of analysis, the reaction test about catalyst is conducted. The result of this test is the same as the result of adsorption analysis. That means the adsorption analysis is effective in screening the catalyst metal. At the evaluating test, the various types of carrier of catalyst are also compared to Shell 405 to improve catalytic activity. The test result shows the

mejora. Tomando algunos de los indicadores propuestos por Shulman (2005 y sobre la base de los objetivos de los programas de materia, se creó un cuestionario por cada disciplina artística. En la encuesta participaron 103 maestros. Los resultados indican que muchos de ellos poseen una formación disciplinar sólida. Sin embargo, también se detectaron defciencias importantes. Muchos carecen de estudios profesionales en las artes, desconocen las propuestas metodológicas más importantes en educación artística y existe falta de participación en cursos de formación continua. Finalmente, algunos maestros desconocen la existencia de los materiales didácticos que proporciona la Secretaría de Educación Pública. Por lo anterior, es muy importante que el IEA mantenga un diálogo abierto con sus maestros, favorezca la profesionalización de los docentes y promueva la impartición de cursos de educación continua y talleres que le permitan mantenerse actualizado y conocer los materiales a su disposición

Santafé de Bogotá, noviembre 21 de 1991
Son varias las semblanzas que distinguidas personalidades de Colombia y del exterior han escrito sobre el Profesor Luis Patiño Camargo, cuya vida ejemplar dejó honda huella en la medicina y la ciencia colombianas: Carlos Lleras Restrepo y Juan Lozano y Lozano en 1978; Augusto Gast Galvis, Fernando Serpa Flórez y Alfonso Jaram illo Salazar en 1979; Eduardo Guzmán Esponda, Remando Groot y José Francisco Socarrás en 1981; Amador Neghme, de Chile en 1987; Ernesto Andradc Valderrama en 1988, y ahora Carlos Sanmartín Barberi.
“Bella vida y bella muerte la de Luis Patiño Camargo, pensaba yo cuando iba caminando detrás del féretro, después de los sencillos oficios en la iglesia de Iza, hacia el cementerio campesino donde él dispuso que se enterrara en medio de las tumbas de sus padres y debajo de los pinos que plantó con su propia mano”. Así inició Carlos Lleras Restrepo un sentido artículo sobre Patiño Camargo publicado en la Nueva Frontera a los pocos días de su muerte, acaecida en Sogamoso el 13 de noviembre de 1978. Porque ese fue su deseo: reposar para siempre en el cementerio que domina su bello pueblo andino, Iza, donde había nacido el 24 de noviembre de 1891.
Dijo Gast Galvis: “El Dr. Patiño, como el cacique de Inza, después de mucho peregrinar por todo el territorio colombiano, encontró un lugar de brisas tibias, cielo siempre azul, abundantes aguas, suelo fértil, en donde se pudiera vivir y morir en paz”.

The Glaciology Group of the Niels Bohr Institute, University of Copenhagen, was assigned the task...... of providing drilling capability for these projects, as it had done for the GRIP project. The group decided to further simplify existing deep drill designs for better reliability and ease of handling. The drill design decided upon was successfully tested on Hans Tausen Ice Cap, Peary Land, Greenland, in 1995....... The 5.0 m long Hans Tausen (HT) drill was a prototype for the ~11 m long EPICA and NorthGRIP versions of the drill which were mechanically identical to the HT drill except for a much longer core barrel and chips chamber. These drills could deliver up to 4 m long ice cores after some design improvements...

The psychoanalytic process in the treatment of Little Hans.

Science.gov (United States)

Bierman, Joseph S

2007-01-01

This paper studies the psychoanalytic process in the treatment of Little Hans, using Samuel Abrams's 1988 paper in which he defines the psychoanalytic process as the sequence of steps which appears within the mind of the patient as the treatment proceeds. As with the adult, the child can affectively recall or reenact the past in the transference, but the child also tries to promote whatever developmental phase is being clocked in. In January 1908 Max Graf, Hans's father and a member of the Vienna Psychoanalytic Society who was a musicologist, wrote Freud that his son had developed a fear that a horse would bite him in the street. Freud first suggested that the father give his son some enlightenment in the matter of sexual knowledge, such as his mother and other females have no "widdlers." The enlightenments only increased Hans's anxiety, prompting Freud to meet with Hans and his father and interpret the fear of the horse as fear of the father. While Max Graf was able to help Hans understand some dreams and fantasies, he exhibited a punitive attitude toward Hans's masturbation, which was reinforced by Freud's attitude that it was harmful. The father did not promote his son's development when he withheld knowledge of how babies are born, neither did Freud when he withheld any contrary suggestions from the father.

Management of radioactive waste at Novi Han Repository

International Nuclear Information System (INIS)

Stefanova, I.G.; Mateeva, M.D.; Milanov, M.V.

2002-01-01

The Novi Han Repository is the only existing repository in Bulgaria for the disposal of radioactive waste from nuclear applications in industry, medicine and research. The repository was constructed in the early sixties according to the existing requirements. It was operated by the Institute for Nuclear Research and Nuclear Energy for more than thirty years without any accident or release of radioactivity to the environment, but without any investment for upgrading. As a consequence, the Bulgarian Nuclear Safety Authority temporarily stopped the operation of the repository in 1994. The measures for upgrading the Novi Han Repository, supported by the IAEA under TC Project BUL/4/005 'Increasing Safety of Novi Han Repository', are presented in this paper. They comprise: assessment of radionuclide inventory and future waste arisings, characterisation of disposal vaults, characterisation of the site, safety assessment, upgrading of the monitoring system, option study for the selection of treatment and conditioning processes and the development of a conceptual design for low and intermediate level waste processing and storage facility, immediate measures for improvement of the existing disposal vaults and infrastructure, construction of above-ground temporary storage structures, and resuming the operation of the Novi Han Repository. The necessary activities for re-licensing of the Novi Han Repository, construction of a waste processing and storage facility and a disposal facility for spent sealed sources are discussed. (author)

Se apoya en teorías sociológicas y educativas: Heller, Bourdieu, Freire, Gramsci; así como autores del ocio: Sue y Cuenca. Describe datos obtenidos de un estudio de caso sobre las vivencias de ocio, desde una narrativa fenomenológica, obtenidos de entrevistas. La etnografía en el aula se empleó para describir la práctica docente e identificar las estructuras de ésta. La hermenéutica auxilió en la interpretación de estos datos y en la construcción de los siguientes tipos ideales de ocio-práctica docente: un ocio aburrido se asocia a una maestra autoritaria, o, a un maestro que renuncia a educar; un ocio creativo a maestras y maestros emancipadores; un ocio híbrido a maestros y maestras en ciernes, que aún no definen un tipo de práctica docente. Se concluye que el ocio sí está presente en la práctica docente, que no hay fronteras per se entre lo público y privado. El maestro y maestra es más que un profesionista cuando está frente a grupo, es una persona que pone en juego lo que es y tiene. El ocio imprime una característica singular a la práctica docente como apropiación de conocimientos y cultura.Abstract: This article contains the results of a research study on the tie between leisure time activities and teaching methods among elementary school teachers in the City of Santiago de Querétaro, México.

Knowledge of population structure is very important for forensic genetics. However, the population substructure in Central-Southern China Han nationality has still not been fully described. In this study, we investigated the genetic diversity of 15 forensic autosomal STR loci from 6879 individuals in 12 Han populations subdivided by administrative provinces in Central-Southern China. The statistical analysis of genetic variation showed that genetic differentiation among these populations was very small with a F st value of 0.0009. The Discriminant Analysis of Principal Components (DAPC) showed that there were no obvious population clusters in Central-Southern China Han population. In practice, the population structure effect in Central-Southern China Han population can be negligible in forensic identification and paternity testing. Copyright © 2017. Published by Elsevier B.V.

We introduce a new technique of interpolation of the energy-loss function (ELF) in solids sampled by empirical optical spectra. Finding appropriate interpolation methods for ELFs poses several challenges. The sampled ELFs are usually very heterogeneous, can originate from various sources thus so called “data gaps” can appear, and significant discontinuities and multiple high outliers can be present. As a result an interpolation based on those data may not perform well at predicting reasonable physical results. Reliable interpolation tools, suitable for ELF applications, should therefore satisfy several important demands: accuracy and predictive power, robustness and computational efficiency, and ease of use. We examined the effect on the fitting quality due to different interpolation schemes with emphasis on ELF mesh optimization procedures and we argue that the optimal fitting should be based on preliminary log–log scaling data transforms by which the non-uniformity of sampled data distribution may be considerably reduced. The transformed data are then interpolated by local monotonicity preserving Steffen spline. The result is a piece-wise smooth fitting curve with continuous first-order derivatives that passes through all data points without spurious oscillations. Local extrema can occur only at grid points where they are given by the data, but not in between two adjacent grid points. It is found that proposed technique gives the most accurate results and also that its computational time is short. Thus, it is feasible using this simple method to address practical problems associated with interaction between a bulk material and a moving electron. A compact C++ implementation of our algorithm is also presented.

More than 80 pieces of T'ang Dynasty and 40 Han Dynasty style ceramic wares have been analysed to determine the amount of thermoluminescence (TL) accumulated since the initial firing of the object and the level of the radiation flux which has created the TL. This paper presents a summary of the thermoluminescence analysis results. Approximately 60% of Han ceramics and 45% of the T'ang pottery authenticated have been shown to belong to periods other than that stylistically suggested. Items which have been found not to be of the anticipated antiquity generally fall into distinct age groups. Of the T'ang wares the most commonly copied item is found to be the horse and for the Han pieces, human figures and ewers/pots/vases represent the most frequently reproduced wares

Y para reconocer este proceso de socialización anticipada, vamos a tomar como variables significativas de su construcción, desarrollo y transformación, aquellas que determinan las expectativas de su ejercicio profesional, así como diversos aspectos que son importantes en las relaciones interpersonales y que denominamos, actitudes y valores sociales. El sistema educativo busca su consolidación y mantenimiento a través de las acciones de sus agentes, principalmente el profesorado. Las acciones de éstos últimos (cumplimiento de normas administrativas y orientaciones educativas, son adoptadas de una forma rutinaria y pautada, es decir son interiorizadas por el profesorado, a lo largo de un proceso de socialización, que si bien dura desde que éste se inicia en las Escuelas de Magisterio hasta su jubilación, tiene un momento de especial y honda raigambre, que es el momento inicial de su formación, cuando los jóvenes individuos son más receptivos a las novedades culturales, y por tanto a la aceptación de cuanto constituyen normas y valores propios de un sistema al que se desea acceder, por el procedimiento socialmente sancionado de la formación reglada en la Escuela de Magisterio. Es el reconocimiento social del maestro, y por extensión de la diplomatura universitaria, la que nos invita a reflexionar sobre el proceso de socialización que se produce dentro de la Universidad a lo largo de los tres años de carrera, entendiendo este proceso, como una combinación entre la adquisición de unos conocimientos y una formación académica, con la adquisición de unas ideas o modelos acerca de la profesión, con la que los jóvenes se enfrentarán al mercado de trabajo.

Full Text Available This is the story of the thirteenth-century stone choir stalls in the cathedral at Santiago in Galicia in north-west Spain. The stalls were constructed under the supervision of one 'Maestro Mateo' and completed in about the year 1200. Four hundred years later the stalls were demolished and replaced with a wooden version when liturgical changes demanded new seating arrangements. Fragments of the decorative stonework were then re-cycled, dumped, buried and dispersed and largely forgotten until 1900 when excavations began in the cathedral. New discoveries enabled small sections of the choir to be reconstructed in the 1960s and 1970s. The major group of stonework was then recovered in 1978 (photographs of excavation work in progress reveal this to have been a robust operation [see figure 1]. This was followed by publications and the financial support of the non-profit-making Fundación Pedro Barrié de la Maza in 1995. By 1999 the process of consolidation and restoration of 17 'seats' was complete, new pieces in the possession of the cathedral combining with the old to 're-create' the original. The results can be seen in the museum of the Cathedral of Santiago. The CD-ROM reviewed here is spin-off from that reconstruction project.

Full Text Available In the carpenter’s guild of Valencia in the Middle Ages, experience and skill were two notions captured in the more comprehensive idea of expertise. The appreciation of this added value made the expert an indispensable figure inside the guild. He was present in the different positions of control and inspection established by by-laws, which ensured the quality of goods manufactured, the proper level of teaching, and the accreditation of new masters. This figure also acted as an expert assessor, estimating the work of a colleague of even assessing the value of his interventions. In this article we examine the notion of expert in medieval carpentry and the infl uence of his practical application in the daily routine of woodworkers.En la carpintería medieval valenciana, la experiencia y la destreza eran dos nociones complementarias de la idea más amplia de pericia. La apreciación de este valor añadido hacía del experto una figura imprescindible en la corporación de oficios, a través de los diversos encargos de control e inspección arbitrados por los estatutos para asegurar la calidad en la factura y en la enseñanza desarrollada por cada maestro, así como en los exámenes de magisterio. El experto también estaba presente en las tasaciones periciales, en las que su juicio servía para certificar la aptitud de la obra realizada por un colega o incluso valorar su intervención. En este artículo examinaremos la noción de experto en l’art de la fusteria o carpintería medieval valenciana y en qué medida su aplicación práctica afectaba al trabajo cotidiano de un maestro carpintero en los siglos XIV al XVI.

Full Text Available Abstract:Parent-teacher communication is crucial to children’s education. The literature reveals that parents’ involvement in their children’s education improves outcomes in areas such as learning, attendance, behavior, and graduation rates. Increased and meaningful communication between home and school is likely to enhance parent involvement and may consequently support students’ learning. Schools are using various forms of technology to increase school/home communication, including voice mail, e-mail, school and classroom websites, and web access to individual student information such as attendance, grades, and student portfolios; however, this use is not consistent or widespread. This paper examines the most prevalent parent-teacher communication in a K-12 educational setting and explores various communication options to improve parent-teacher communication. The focus is to examine the communication needs between teacher and parents and the benefits of combining traditional synchronous and asynchronous communication with newer communication technologies to meet these needs.Resumen:La comunicación entre padres y maestros es crucial para la educación de los niños.

Copy number variation (CNV) is a valuable source of genetic diversity in the human genome and a well-recognised cause of various genetic diseases. However, CNVs have been considerably under-represented in population-based studies, particularly the Han Chinese which is the largest ethnic group in the world. To build a representative CNV map for the Han Chinese population. We conducted a genome-wide CNV study involving 451 male Han Chinese samples from 11 geographical regions encompassing 28 dialect groups, representing a less-biased panel compared with the currently available data. We detected CNVs by using 4.2M NimbleGen comparative genomic hybridisation array and whole-genome deep sequencing of 51 samples to optimise the filtering conditions in CNV discovery. A comprehensive Han Chinese CNV map was built based on a set of high-quality variants (positive predictive value >0.8, with sizes ranging from 369 bp to 4.16 Mb and a median of 5907 bp). The map consists of 4012 CNV regions (CNVRs), and more than half are novel to the 30 East Asian CNV Project and the 1000 Genomes Project Phase 3. We further identified 81 CNVRs specific to regional groups, which was indicative of the subpopulation structure within the Han Chinese population. Our data are complementary to public data sources, and the CNV map may facilitate in the identification of pathogenic CNVs and further biomedical research studies involving the Han Chinese population. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Full Text Available Decomposition of hydroxylammonium nitrate (HAN solution with electrolytic decomposition method has attracted much attention in recent years due to its efficiencies and practicability. However, the phenomenon has not been well-studied till now. By utilizing mathematical model currently available, the effect of water content and power used for decomposition was studied. Experiment data shows that sacrificial material such as copper or aluminum outperforms inert electrodes in the decomposition of HAN solution. In the case of using copper wire to electrolyse HAN solutions, approximately 10 seconds is required to reach 100 °C regardless of concentration of HAN. In term of power consumption, 100 W–300 W was found to be the range in which decomposition could be triggered effectively using copper wire as electrodes.

Ancient Di-Qiang people once resided in the Ganqing region of China, adjacent to the Central Plain area from where Han Chinese originated. While gene flow between the Di-Qiang and Han Chinese has been proposed, there is no evidence to support this view. Here we analyzed the human remains from an early Di-Qiang site (Mogou site dated ~4000 years old) and compared them to other ancient DNA across China, including an early Han-related site (Hengbei site dated ~3000 years old) to establish the underlying genetic relationship between the Di-Qiang and ancestors of Han Chinese. We found Mogou mtDNA haplogroups were highly diverse, comprising 14 haplogroups: A, B, C, D (D*, D4, D5), F, G, M7, M8, M10, M13, M25, N*, N9a, and Z. In contrast, Mogou males were all Y-DNA haplogroup O3a2/P201; specifically one male was further assigned to O3a2c1a/M117 using targeted unique regions on the non-recombining region of the Y-chromosome. We compared Mogou to 7 other ancient and 38 modern Chinese groups, in a total of 1793 individuals, and found that Mogou shared close genetic distances with Taojiazhai (a more recent Di-Qiang population), Hengbei, and Northern Han. We modeled their interactions using Approximate Bayesian Computation, and support was given to a potential admixture of ~13-18% between the Mogou and Northern Han around 3300-3800 years ago. Mogou harbors the earliest genetically identifiable Di-Qiang, ancestral to the Taojiazhai, and up to ~33% paternal and ~70% of its maternal haplogroups could be found in present-day Northern Han Chinese.

Next-generation sequencing provides a high-resolution insight into human genetic information. However, the focus of previous studies has primarily been on low-coverage data due to the high cost of sequencing. Although the 1000 Genomes Project and the Haplotype Reference Consortium have both provided powerful reference panels for imputation, low-frequency and novel variants remain difficult to discover and call with accuracy on the basis of low-coverage data. Deep sequencing provides an optimal solution for the problem of these low-frequency and novel variants. Although whole-exome sequencing is also a viable choice for exome regions, it cannot account for noncoding regions, sometimes resulting in the absence of important, causal variants. For Han Chinese populations, the majority of variants have been discovered based upon low-coverage data from the 1000 Genomes Project. However, high-coverage, whole-genome sequencing data are limited for any population, and a large amount of low-frequency, population-specific variants remain uncharacterized. We have performed whole-genome sequencing at a high depth (∼×80) of 90 unrelated individuals of Chinese ancestry, collected from the 1000 Genomes Project samples, including 45 Northern Han Chinese and 45 Southern Han Chinese samples. Eighty-three of these 90 have been sequenced by the 1000 Genomes Project. We have identified 12 568 804 single nucleotide polymorphisms, 2 074 210 short InDels, and 26 142 structural variations from these 90 samples. Compared to the Han Chinese data from the 1000 Genomes Project, we have found 7 000 629 novel variants with low frequency (defined as minor allele frequency genome. Compared to the 1000 Genomes Project, these Han Chinese deep sequencing data enhance the characterization of a large number of low-frequency, novel variants. This will be a valuable resource for promoting Chinese genetics research and medical development. Additionally, it will provide a valuable supplement to the 1000

Aim To compare maternal and neonatal outcomes of Tibetan and Han Chinese women delivering vaginally at high altitude (3650 meters) in Lhasa, Tibet Autonomous Region, People’s Republic of China. Method Comparative analysis of data from a prospective observational study of Tibetan (n = 938) and Han Chinese (n = 146) women delivering at three hospitals between January 2004 and May 2005. Results Han Chinese women had higher rates of pre-eclampsia/gestational hypertension than Tibetan women, (10.3% vs 5.9%, P = 0.04). There was no difference in rates of postpartum hemorrhage between Tibetan and Han women (12.8% vs 17.1%, P = 0.15). Han newborns weighed significantly less than Tibetan newborns (P < 0.01), and were twice as likely to be small for gestational age, (24.5% vs 11.6%, P < 0.01). Tibetan newborns were less likely to have poor neonatal outcomes than Han newborns (P < 0.01). Conclusion In high altitude deliveries in Tibet, adverse outcomes were significantly more common among Han Chinese. PMID:19012697

This report presents briefly the most important issues of the study performed by EQE - Bulgaria. The objectives of the study are the development of conceptual solutions for construction of the following facilities in the Novi Han radioactive waste repository: an operational storage for unconditioned high level spent sources; new temporary buildings over the existing radioactive waste storage facilities; a rain-water draining system ect. The study also includes the engineering solutions for conservation of the existing facilities, currently full with high level spent sources. A 'Program for reconstruction and modernization' has been created, including the analysis of some regulation aspects concerning this program implementation. In conclusions the engineering problems of Novi Han repository are clear and appropriate solutions are available. They can be implemented in both cases of 'small' or 'large' reconstruction. The reconstruction project anyway should start with the construction of a new site infrastructure. Reconstruction and modernization of Novi Han radioactive waste repository is the only way to improve the management and safety of radioactive waste from medicine, industry and scientific research in Bulgaria

Our study aimed to comprehensively investigate the genetic polymorphisms of CYP3A4 in Han Chinese. We sequenced the gene regions of CYP3A4, including its promoter, exons, surrounding introns and 3' untranslated region (3'UTR), from 100 unrelated-healthy Han Chinese individuals. We detected 11 SNPs, three of which are novel. According to in silico functional prediction of novel variants, 20148 A>G in exon 10, resulting in substitution of Tyr319 with Cys (CYP3A4*21), may induce dramatic alteration of protein conformation, and 26908 G>A in 3'UTR may disrupt post-transcriptional regulation. We identified five alleles in Han Chinese, the allele frequencies of CYP3A4*1, *5, *6, *18 and *21 are 97, 0.5, 1, 1 and 0.5%, respectively. Haplotype inference revealed 14 haplotypes, of which the major haplotype CYP3A4*1A constitutes 59% of the total chromosomes. We also examined the possible role of natural selection in shaping the variation of CYP3A4 and confirmed a trend, consistent with the action of positive selection. We systematically screened the genetic polymorphisms of CYP3A4 in Han Chinese, highlighted possible functional impairment of the novel allele and summarized the distinct allele and haplotype frequency distribution, with an emphasis on detecting the footprint of recent positive selection on the CYP3A4 gene in Han Chinese.

Full Text Available Se pretende conocer las creencias de los estudiantes de maestro de educación infantil acerca de la multiculturalidad, y comprender cómo se desarrolla la competencia intercultural en el proceso de formación inicial en la Facultad de Educación de Albacete de la Universidad de Castilla-La Mancha (UCLM, España. Los participantes fueron 172 estudiantes. El diseño se enmarca en el paradigma de Mixed Methods, definido como la integración sistemática de métodos de investigación cualitativos y cuantitativos en un estudio. A tal efecto, para realizar la investigación se elaboró un cuestionario de 25 preguntas, cuyos resultados se analizaron con el SPSS 20.0. Paralelamente, se construyeron los guiones de las entrevistas individuales y de los grupos de discusión, cuyo análisis fue efectuado con el Atlas.ti 6. La validez y fiabilidad quedaron garantizadas con técnicas como la revisión teórica, la aplicación piloto, el juicio de expertos y la aplicación del Alfa de Cronbach (0,861. Los resultados mostraron que la formación de la competencia intercultural de los futuros maestros de educación infantil fue deficiente. Según los estudiantes, el plan de estudios no mejoró la competencia intercultural cognitiva, pedagógica y emotiva, pues al final de los estudios tenían prejuicios y estereotipos culturales negativos hacia las personas extranjeras, que durante el plan de estudios solo consiguieron suavizarlos, pero no eliminarlos.

To investigate the relevant prognostic factors and their differences between colorectal cancer (CRC) patients of Chinese Han and Hui ethnicities in the Beijing region. A retrospective analysis of 880 patients diagnosed with CRC at Xuanwu Hospital, Capital Medical University between September 2001 and September 2011 was performed. Among the 880 patients, 398 and 482 were Hui and Han, respectively. Characteristics including sex, age, diet, tumor size, primary tumor site, Dukes' stage and degree of differentiation were analyzed for their influence on prognosis. Data on dietary structures were recorded through a questionnaire survey conducted during the patient's first visit, return visit or follow-up checkups. Among patients with colon cancer, the 5-year survival rate for patients of Hui ethnicity was lower than that for Han patients (P = 0.025). Six risk factors (age of onset, dietary structure, tumor size, Dukes' stage, location of cancer and degree of differentiation) in both Han and Hui patients were identified as prognostic factors (P dietary structure was a statistically significant factor, and diet varied significantly between the two ethnic groups. Dietary structure has a significant influence on colon cancer prognosis among Han and Hui patients with colon cancer in Beijing, which may cause a difference in their survival rates.

Full Text Available We aimed to investigate differences in inhibitory control ability between proficient and non-proficient Dai–Han bilinguals. Two experiments used a combined stimulus–stimulus and stimulus–response compatibility paradigm for this purpose. Participants were Dai–Han bilingual primary-school students selected from a Dai-speaking town in Yunnan province, China. In Dai language interference condition, participants were asked to complete a picture category task. Results showed that the effect of attentional control for non-proficient bilinguals (NPBs was significantly greater than that for proficient bilinguals (PBs, while the effect of response inhibition was not. This implied that a difference in inhibitory control between PBs and NPBs appeared at the attention control stage when interference by the Dai lexicon emerged. In Han language interference condition, however, participants were also asked to complete the same task. Results showed that the effect of response inhibition for NPBs was significantly greater than that for PBs, but the effect of attentional control was not. This demonstrated that a difference in inhibitory control emerged at the response inhibition stage when interference by the Han lexicon emerged. This pattern of results is opposite to previous researches, which indicated that the difference between PBs and NPBs occurred at the response inhibition stage under first language condition, whereas at the attentional control stage under second language (L2 condition. Based on these, this study suggests that Dai–Han bilinguals showed a remarkable L2 advantage. In addition, results showed that response times (RTs of PBs were faster than RTs of NPBs while confounding variables (e.g., intelligence, etc. were under control. This indicates that the inhibitory control ability of the PBs is superior to that of NPBs in this study.

The Maestro for MER (Mars Exploration Rover) software is the premiere operation and activity planning software for the Mars rovers, and it is required to deliver all of the processed image products to scientists on demand. These data span multiple storage arrays sized at 2 TB, and a backup scheme ensures data is not lost. In a catastrophe, these data would currently recover at 20 GB/hour, taking several days for a restoration. A seamless solution provides access to highly durable, highly available, scalable, and cost-effective storage capabilities. This approach also employs a novel technique that enables storage of the majority of data on the cloud and some data locally. This feature is used to store the most recent data locally in order to guarantee utmost reliability in case of an outage or disconnect from the Internet. This also obviates any changes to the software that generates the most recent data set as it still has the same interface to the file system as it did before updates

La relevancia del estudio se plantea desde la necesidad de conocer este período histórico en el cual se inscribió la mayoría de las historias de vida de las maestras que analizamos en Colombia. Al respecto, nos preguntamos sobre ¿cuáles son las políticas públicas e imaginarios que se han presentado en la legislación y financiación del educador colombiano, en el nivel de la primaria, y la aplicabilidad y variabilidad de la norma, mediados por los sindicatos de maestros de 1952 a 1994? Nos sustentamos en la historia política bajo el marco conceptual de la historia social de la educación y las mentalidades. La metodología comparada bajo criterios de políticas gubernamentales en la financiación de la educación, movimientos de maestros por medio de sindicatos, escalafón docente y salarios nos permitieron analizar el impacto y el imaginario social del educador colombiano. Las estrategias se orientan desde el análisis de la legislación hasta los casos concretos de hechos históricos que motivaron cambios en la normativa docente. En este sentido, tomamos como antecedentes, en la época colonial, la reforma de 1774 y el en siglo XIX nos centramos en la de 1870 y 1892. En el siglo XX nos centramos en el período de 1913 a 1952.

Hans Christian Orsted (1777-1851) is of great importance as a scientist and philosopher far beyond the borders of Denmark and his own time. At the centre of an international network of scholars, he was instrumental in founding the world picture of modern physics. Orsted was the physicist who brought Kant's metaphysics to fruition. In 1820 his discovery of electro-magnetism, a phenomenon that could not possibly exist according to his adversaries, changed the course of research in physics. It inspired Michael Faraday's experiments and discovery of the adverse effect, magneto-electric induction. The two physical phenomena were later described in mathematical equations by J.C. Maxwell. Together these discoveries constitute the prerequisites for the overwhelming development of modern technology. But Orsted was also one of the cultural leaders and organizers of the Danish Golden Age (together with Grundtvig, Kierkegaard, and Hans-Christian Andersen, his protege), and made significant contributions to aesthetics, ph...
["Snow" and "Walpurgisnacht". Hans Castorp's exemplary maturation crises in "Zauberberg"].

Science.gov (United States)

Heinrich, K; Walter, C

1995-01-01

On the occasion of a rather incidental visit in the sanatorium "Berghof" at Davos, Hans Castorp, the--as to his primary personality--asthenic and low-profile protagonist of the "Zauberberg" is gradually getting caught up in the maelstrom of the there prevailing timelessness and irresponsibility, this being interrupted solely by two tapering to crisis episodes: his amouressness to Mme. Chauchat as an erotic crisis and by the visionary daydream during a snowstorm about the abilities of men as a cognitive, mental crisis. Both events are triggered by a pathoid irritability, following the maxim of Th. Mann that illness, decay and death as borderline experiences may be the presupposition for cognition and reversal. Both crises end without consequences--the "Zauberberg" is the negation of the novel of education and development in the narrower sense. The unsuccessfulness and undecidedness of Hans Castorp's existence culminate in the open end of the novel, regarding his surviving on the battle field, and is in strict contrast to Adrian Leverkühn's determined autoinfection with Lues with the aim of artistic perfection and the creative break-through of "Doctor Faustus". Hans Castorp's regression and self-fragmentation within the decadent-morbid atmosphere of the sanatorium lead to his storming into the battles of the First World War as a last and existential crisis; it is here where finally the individual and national fate are merging. Hans Castorp becomes the paradigma of the German pre-war bourgeoisie and its crisis-prone development.
The spatially resolved characterisation of Egyptian blue, Han blue and Han purple by photo-induced luminescence digital imaging.

The photo-induced luminescence properties of Egyptian blue, Han blue and Han purple were investigated by means of near-infrared digital imaging. These pigments emit infrared radiation when excited in the visible range. The emission can be recorded by means of a modified commercial digital camera equipped with suitable glass filters. A variety of visible light sources were investigated to test their ability to excite luminescence in the pigments. Light-emitting diodes, which do not emit stray infrared radiation, proved an excellent source for the excitation of luminescence in all three compounds. In general, the use of visible radiation emitters with low emission in the infrared range allowed the presence of the pigments to be determined and their distribution to be spatially resolved. This qualitative imaging technique can be easily applied in situ for a rapid characterisation of materials. The results were compared to those for Egyptian green and for historical and modern blue pigments. Examples of the application of the technique on polychrome works of art are presented.

To systematically investigate the genetic polymorphisms of the CYP3A4 gene in a Han Chinese population. The promoter and exons of CYP3A4 gene in 1114 unrelated, healthy Han Chinese subjects were amplified and genotyped by direct sequencing. In total, five previously reported alleles (*1G, *4, *5, *18B and *23) were detected, of which one allele (*23) was reported for the first time in Han Chinese population. Additionally, seven novel exonic variants were also identified and designated as new alleles CYP3A4*28-*34. This study provides the most comprehensive data of CYP3A4 polymorphisms in Han Chinese population and detects the largest number of novel CYP3A4 alleles in one ethnic group.

Durante las últimas décadas han sido ampliamente discutidas y suficientemente argumentadas, las relaciones y particularidades de la lengua y la literatura como realidades presentes, mas no siempre reconocidas, en el currículo escolar. Al respecto, los diferentes documentos de política pública para la enseñanza del lenguaje en Colombia, plantean orientaciones de naturaleza epistémica, disciplinar y pedagógica cuyo propósito es guiar al maestro en su acción pedagógica. Sin embargo, esto no resulta suficiente para transformar la práctica docente.

Allele frequencies and forensic statistical parameters for 12 STRs contained in the Investigator HDplex Kit (D2S1360, D3S1744, D4S2366, D5S2500, SE33, D6S474, D7S1517, D8S1132, D10S2325, D12S391, D18S51, and D21S2055) were estimated from a sample of 503 unrelated individuals from the Guangdong Han population of South China. No significant departure from the Hardy-Weinberg equilibrium or genetic linkage disequilibrium was observed (after Bonferroni correction). The expected heterozygosity ranged from 0.6411 to 0.9414. The allele frequencies in Guangdong Han significantly differed from that in Shanghai Han, Korea, Northern Italian, Swedish, Dutch, Somalia, and Argentinean populations at 2 to 12 loci. The markers included in the kit have highly polymorphic information that could be used for forensic DNA analysis as potential tools for differentiating Han population from other populations in the world.

To investigate the association of ghrelin gene polymorphisms with metabolic syndrome in Han Nationality Chinese. A total of 240 patients with metabolic syndrome and 427 adults aged above forty years were recruited. Genotypes were determined by polymerase chain reaction and restriction fragment length polymorphism analysis. The allelic frequency of the Leu72Met polymorphism was 17.3% in the patient group and 11.9% in the control group (chi2 = 7.36, P = 0.007). Metabolic syndrome was more prevalent among carriers of the Met72 variant (43.8 vs 33.1%, age- and sex-adjusted odds ratio = 1.57, P = 0.01). No Arg51Gln variants were found in our study subjects. Rather than being associated with its individual components, Leu72Met polymorphism is associated with metabolic syndrome in the Han Nationality Chinese. Arg51Gln polymorphism is rare in the Han Nationality Chinese.

Attachment and sibling rivalry in Little Hans: the fantasy of the two giraffes revisited.

Science.gov (United States)

Wakefield, Jerome C

2007-01-01

Freud's interpretation of Little Hans's "phantasy of the two giraffes" is pivotal to his oedipal analysis that Hans has inchoate desires for sexual intercourse with his mother. Bowlby argued that Freud's focus on his oedipal theory led him to ignore preoedipal attachment-related factors that have equal plausibility in explaining the clinical data. However, Bowlby did not attempt to apply the attachment perspective to the interpretation of Hans's fantasies that form the core of the case material. A microanalysis of Hans's giraffe fantasy and the evidence used to support Freud's claims about it yields an attachment-based sibling rivalry account arguably of greater explanatory power than the oedipal account. Consistent with Bowlby's hypothesis, the evidence suggests that Hans's giraffe fantasy is about the sibling rivalry triangle involved in caregiver attachment access, rather than (or in addition to) the oedipal triangle. The issue of multiple levels of meaning and the methodological challenges raised by multiple determination is also considered. The giraffe fantasy's attachment-theoretic explanation encourages a rethinking of this classic case and strengthens Bowlby's claim that the case is fruitfully viewed from an attachment perspective.

In this study, we analyzed 18 autosomal STRs on 3550 unrelated individuals collected from the Han population of Changchun. No significant deviation from Hardy-Weinberg equilibrium was observed at all STR loci, and the expected heterozygosity ranged from 0.6275 to 0.9207. The combined match probability (CMP) was 2.42 × 10 - 22 , and the combined power of discrimination (CPD) was 99.9999999999999999999758 %. Changchun Han showed no significant difference between northern and eastern Han populations at nearly all STR loci, but had significant differences between southern Han at multiple STRs, as well as other Chinese ethnic populations. The phylogenetic analysis also showed that Changchun Han is genetically close to northern Hans, suggesting that the Han population of Changchun could mainly come from northern China.

Full Text Available In the present study, we investigated the genetic characteristics of 25 Y-chromosomal and 15 autosomal short tandem repeat (STR loci in 305 unrelated Han Chinese male individuals from Liaoning Province using AmpFISTR® Yfiler® Plus and IdentifilerTM PCR amplification kits. Population comparison was performed between Liaoning Han population and different ethnic groups to better understand the genetic background of the Liaoning Han population. For Y-STR loci, the overall haplotype diversity was 0.9997 and the discrimination capacity was 0.9607. Gene diversity values ranged from 0.4525 (DYS391 to 0.9617 (DYS385. Rst and two multi-dimensional scaling plots showed that minor differences were observed when the Liaoning Han population was compared to the Jilin Han Chinese, Beijing Han Chinese, Liaoning Manchu, Liaoning Mongolian, Liaoning Xibe, Shandong Han Chinese, Jiangsu Han Chinese, Anhui Han Chinese, Guizhou Han Chinese and Liaoning Hui populations; by contrast, major differences were observed when the Shanxi Han Chinese, Yunnan Bai, Jiangxi Han Chinese, Guangdong Han Chinese, Liaoning Korean, Hunan Tujia, Guangxi Zhuang, Gansu Tibetan, Xishuangbanna Dai, South Korean, Japanese and Hunan Miao populations. For autosomal STR loci, DP ranged from 0.9621 (D2S1338 to 0.8177 (TPOX, with PE distributing from 0.7521 (D18S51 to 0.2988 (TH01. A population comparison was performed and no statistically significant differences were detected at any STR loci between Liaoning Han, China Dong, and Shaanxi Han populations. The results showed that the 25 Y-STR and 15 autosomal STR loci in the Liaoning Han population were valuable for forensic applications and human genetics, and Liaoning Han was an independent endogenous ethnicity with a unique subpopulation structure.

The first Koç Han: Pioneering modern architecture in Ankara

Directory of Open Access Journals (Sweden)

Oya Atalay Franck

2013-01-01

Full Text Available Koç Holding is the most established conglomerate in Turkey. Th e company’s beginnings date from the mid 1920s, when Ahmet Vehbi Koç, founder of Koç Holding, had his first own company registered with the Ankara Chamber of Commerce. In 1932, Koç moved his business from his father’s store on Anafartalar Street to a new building, the first Koç Han, erected the same year on Çankırı Street Nr.13 in Ulus. Th e building’s designer was Swiss-Austrian architect Ernst Arnold Egli, who had come to Turkey only five years earlier upon invitation by the government to work as chief architect of the Ministry of National Education. During his stay, which lasted from 1927 until 1940, Egli realized about 40 projects and worked on many more. Koç Han is the rare example of a commercial building by Egli. At a time when the urban aspect of the old town center of Ankara consisted mostly of one-or two-storeyed stone-and-wood houses, the first Koç Han represented an altogether new building type for the town, in being a multipurpose edifice with space for shops at street level, with large storage facilities below ground, and providing off ices and housing on the upper fl oors. Th e functional rigor of the plan and the sober modernism of the building’s facades contrasted strongly with the architecture of the time. In this respect, the first Koç Han was a strong statement regarding Ahmet Vehbi Koç’s belief in a modern Turkey and to the contribution of the building’s architect, Ernst Arnold Egli, to this project.

Full Text Available The Chinese Hui population, as the second largest minority ethnic group in China, may have a different genetic background from Han people because of its unique demographic history. In this study, we aimed to identify genetic differences between Han and Hui Chinese from the Ningxia region of China by comparing eighteen single nucleotide polymorphisms in cancer-related genes.DNA samples were collected from 99 Hui and 145 Han people from the Ningxia Hui Autonomous Region in China, and SNPs were detected using an improved multiplex ligase detection reaction method. Genotyping data from six 1000 Genomes Project population samples (99 Utah residents with northern and western European ancestry (CEU, 107 Toscani in Italy (TSI, 108 Yoruba in Ibadan (YRI, 61 of African ancestry in the southwestern US (ASW, 103 Han Chinese in Beijing (CHB, and 104 Japanese in Tokyo (JPT were also included in this study. Differences in the distribution of alleles among the populations were assessed using χ2 tests, and FST was used to measure the degree of population differentiation.We found that the genetic diversity of many SNPs in cancer-related genes in the Hui Chinese in Ningxia was different from that in the Han Chinese in Ningxia. For example, the allele frequencies of four SNPs (rs13361707, rs2274223, rs465498, and rs753955 showed different genetic distributions (p0.000 between the Hui and Han populations.These results suggest that some SNPs associated with cancer-related genes vary among different Chinese ethnic groups. We suggest that population differences should be carefully considered in evaluating cancer risk and prognosis as well as the efficacy of cancer therapy.

To investigate the changes and clinical significance of plasma adrenomedullin in Han and Tibetan health adult men at the state of chronic hypoxia. The Han health adult who migrated and lived above sea level 4200 meter for 1∼3 years and the native Tibetan were involved in this study. The plasma adrenomedullin levels in both Han and Tibetan health adult men were measured by RIA. The results showed that the plasma adrenomedullin levels of native Tibetan were significantly higher than that of migrated Han worker (P<0.05). The plasma adrenomedullin might play a regulatory role on the physiological function in the health adult men who live in high altitude hypoxic state. (authors)

Full Text Available Objective: To estimate the prevalence of diabetes and identify risk factors in the Uyghur and Han population in Xinjiang, China. Methods: A cross-sectional study in urban and rural areas in Xinjiang, including 2863 members of the Uyghur population and 3060 of the Han population aged 20 to 80 years, was conducted from June 2013 to August 2013. Data on fasting plasma glucose (FPG and personal history of diabetes were used to estimate the prevalence of diabetes. Data on demographic characteristics, lifestyle risk factors, and lipid profiles were collected to identify risks factors using the multivariate logistic regression model. Results: In urban areas, the age- and gender-standardized prevalence of diabetes was 8.21%, and the age- and gender-standardized prevalence of diabetes was higher in the Uyghur population (10.47% than in the Han population (7.36%. In rural areas, the age- and gender-standardized prevalence of diabetes was 6.08%, and it did not differ significantly between the Uyghur population (5.71% and the Han population (6.59%. The results of the multivariate logistic regression analysis showed that older age, obesity, high triglycerides (TG, and hypertension were all associated with an increased risk of diabetes in the Uyghur and Han population. Urban residence and low high-density lipoprotein cholesterol (HDL-C were associated with an increased risk of diabetes in the Uyghur population. Being an ex-drinker was associated with an increased risk of diabetes and heavy physical activity was associated with a decreased risk of diabetes in the Han population. Conclusions: Our study indicates that diabetes is more prevalent in the Uyghur population compared with the Han population in urban areas. Strategies aimed at the prevention of diabetes require ethnic targeting.

Full Text Available In the summer of 1982, Hans-Peter Schultze and Gloria Arratia were invited to a small museum located on a fossiliferous site of the Devonian Escuminac Formation in Miguasha, Quebec, eastern Canada, Hans-Peter was to work with Marius Arsenault, the director of the Miguasha Museum, on the skull of the elpistostegalid Elpistostege watsoni, a species closely related to basal tetrapod. In addition, he went through the collections to describe and measure numerous juvenile specimens of the osteolepiform. Eusthenopteran foordi. As expected, there two projects turned out to be important contributions in lower vertebrate paleontology and systematics: one on the origin of tetrapods (1985, and the second one on growth patterns of a Late Devonian fish (1984. During his visit to Miguasha, Hans-Peter also spent time digging for fossils and drawing numerous specimens in the collection. In addition, in order to help the personnel of the museum to identify some of the Escuminac fished, he created an identification key based on the gross morphology of the scales. For a small group of undergraduate students, hired at the museum during the summer as naturalists, it was a unique opportunity to discuss paleontology with a leading researcher. We were amazed by his willingness to talk to us, even if then most of us only spoke French! For the first time, we were exposed to Hennigian methodology and its usage in vertebrate paleontology during and evening lecture that Hans-Peter prepared for us. His lecture was delightful; it was an intensive course in lower vertebrate anatomy, and an intellectual journey among the philosophers Karl Marx and Karl Popper, the entomologists Willy Hennig and Lars Brundin, and "The Band of Four" (Rosen et al., 1981. It was for most of us our first exposure to science, as it should be done. We were all impressed by his knowledge and above all by his simplicity and friendliness.

The Han Chinese are the largest ethnic group in the world, and their origins, development, and expansion are complex. Many genetic studies have shown that Han Chinese can be divided into two distinct groups: northern Han Chinese and southern Han Chinese. The genetic history of the southern Han Chinese has been well studied. However, the genetic history of the northern Han Chinese is still obscure. In order to gain insight into the genetic history of the northern Han Chinese, 89 human remains were sampled from the Hengbei site which is located in the Central Plain and dates back to a key transitional period during the rise of the Han Chinese (approximately 3,000 years ago). We used 64 authentic mtDNA data obtained in this study, 27 Y chromosome SNP data profiles from previously studied Hengbei samples, and genetic datasets of the current Chinese populations and two ancient northern Chinese populations to analyze the relationship between the ancient people of Hengbei and present-day northern Han Chinese. We used a wide range of population genetic analyses, including principal component analyses, shared mtDNA haplotype analyses, and geographic mapping of maternal genetic distances. The results show that the ancient people of Hengbei bore a strong genetic resemblance to present-day northern Han Chinese and were genetically distinct from other present-day Chinese populations and two ancient populations. These findings suggest that the genetic structure of northern Han Chinese was already shaped 3,000 years ago in the Central Plain area. PMID:25938511

The haplotype diversity reached 0.99999 and the discrimination capacity and match probability were 0.9956 and 0.0011, respectively. The gene diversity values ranged from 0.3942 at DYS438 to 0.9607 at DYS385a/b. Population differentiation within 10 Jiangsu Han subpopulations were evaluated by RST values and visualized in Neighbor-Joining trees and Multi-Dimensional Scaling plots as well as population relationships between the Jiangsu Han population and other 18 Eastern Asian populations. Such results indicated that the 23 Y-STR loci were highly polymorphic in Jiangsu Han population and played crucial roles in forensic application as well as population genetics. For the first time, we reported the genetic diversity of male lineages in Jiangsu Han population at a high-resolution level of 23 Y-STR set and consequently contributed to familial searching, offender tracking, and anthropology analysis of Jiangsu Han population.

For the first time, we reported the genetic diversity of male lineages in Jiangsu Han population at a high-resolution level of 23 Y-STR set and consequently contributed to familial searching, offender tracking, and anthropology analysis of Jiangsu Han population.

To evaluate the value of PowerPlex ® 21 System (Promega) and study the genetic polymorphism of its 20 short-tandem repeat (STR) loci in southern Chinese Han population. We conducted genotyping experiments using PowerPlex ® 21 System on 20 autosomal STR loci (D3S1358, D1S1656, D6S1043, D13S317, Penta E, D16S539, D18S51, D2S1338, CSF1PO, Penta D, TH01, vWA, D21S11, D7S820, D5S818, TPOX, D8S1179, D12S391, D19S433 and FGA) in 2367 unrelated Chinese Han individuals living in South China. The allele frequencies and parameters commonly used in forensic science were statistically analyzed in these individuals and compared with the reported data of other populations. The PowerPlex ® 21 System had a power of discrimination (PD) ranging from 0.7839 to 0.9852 and a power of exclusion (PE) ranging from 0.2974 to 0.8099 for the 20 loci. No significant deviation from Hardy-Weinberg expectations was found for all the loci except for D5S818. This southern Chinese Han population had significant differences in the allele frequencies from 8 ethnic groups reported in China, and showed significant differences at 8 to 20 STR foci from 5 foreign populations. The allele frequency at the locus D1S1656 in this southern Chinese Han population differed significantly from those in the 5 foreign populations and from 3 reported Han populations in Beijing, Zhejiang Province and Fujian Province of China. The neighbor-joining phylogenetictree showed clustering of all the Asian populations in one branch, while the northern Italian and Argentina populations clustered in a separate branch. This southern Chinese Han population had the nearest affinity with the Yi ethnic population in Yunnan Province of China. The 20 STR loci are highly polymorphic in this southern Chinese Han population, suggesting the value of this set of STR loci in forensic personal identification, paternity testing and anthropological study.
Little Hans and attachment theory: Bowlby's hypothesis reconsidered in light of new evidence from the Freud Archives.

Science.gov (United States)

Wakefield, Jerome C

2007-01-01

Bowlby (1973), applying attachment theory to Freud's case of Little Hans, hypothesized that Hans's anxiety was a manifestation of anxious attachment. However Bowlby's evidence was modest; Hans was threatened by his mother with abandonment, expressed fear of abandonment prior to symptom onset, and was separated from his mother for a short time a year before. Bowlby's hypothesis is reassessed in light of a systematic review of the case record as well as new evidence from recently derestricted interviews with Hans's father and Hans in the Freud Archives. Bowlby's hypothesis is supported by multiple additional lines of evidence regarding both triggers of separation anxiety preceding the phobia (e.g., a funeral, sibling rivalry, moving, getting his own bedroom) and background factors influencing his working model of attachment (mother's psychopathology, intense marital conflict, multiple suicides in mother's family) that would make him more vulnerable to such anxiety. Bowlby's hypothesis is also placed within the context of subsequent developments in attachment theory.

Los únicos datos de prevalencia que se tienen en el país proceden de Antioquia pero se desconoce la frecuencia en otras regiones del país. Objetivo: evaluar la percepción de los maestros de escuelas de una localidad de Bogotá sobre la presencia del trastorno de atención en sus alumnos. Material y métodos: se realizaron conferencias magistrales sobre la evolución de la atención durante el desarrollo, las alteraciones que se presentan y se engloban en el término trastorno por déficit de atención y discusiones de grupo. Al finalizar se aplicó una encuesta de seis puntos desarrollados en formato de preguntas abiertas que estaban relacionadas con el número total de niños, la distribución por género y las características de la atención de aquellos que tenían a cargo. Resultados. 58 maestros de 10 escuelas percibieron que 612 (31% alumnos de preescolar y primaria tenían problemas de atención. La distribución por grados mostró un pico importante en el tercer grado. No hubo diferencias significativa en cuanto al género pero si respecto a la preferencia manual. Conclusión. Los datos recogidos demuestran una importante percepción de dificultades de atención en los niños que invita a una reflexión en relación a medidas de tipo pedagógico y de modulación de la conducta, así como a una búsqueda de tipo estadístico y etiológico formal.

Nantong is located in mid-eastern China, and the Han population in Nantong may be greatly affected by population admixture between northern and southern Han Chinese populations. In this study, we analyzed 17 autosomal short tandem repeat (STR) loci on 2923 unrelated individuals collected from the Han population of Nantong. No significant deviation from Hardy-Weinberg equilibrium was observed at all STR loci, and the expected heterozygosity ranged from 0.6184 to 0.9187. The combined match probability (CMP) was 3.87 × 10(-21), and the combined power of discrimination (CPD) was 99.999999999999999999613 %. No significant difference of allele frequencies was observed between Nantong and other Han populations at all STR loci, as well as Dai, Mongolian, and Tibetan. Significant differences were only observed between Nantong Han and Uyghur at TH01, as well as Nantong Han and Dong at CSF1PO and FGA. Nantong Han showed significant differences between She, Bouyei, and Miao at multiple STR loci.

Combining the Hanning windowed interpolated FFT in both directions

Science.gov (United States)

Chen, Kui Fu; Li, Yan Feng

2008-06-01

The interpolated fast Fourier transform (IFFT) has been proposed as a way to eliminate the picket fence effect (PFE) of the fast Fourier transform. The modulus based IFFT, cited in most relevant references, makes use of only the 1st and 2nd highest spectral lines. An approach using three principal spectral lines is proposed. This new approach combines both directions of the complex spectrum based IFFT with the Hanning window. The optimal weight to minimize the estimation variance is established on the first order Taylor series expansion of noise interference. A numerical simulation is carried out, and the results are compared with the Cramer-Rao bound. It is demonstrated that the proposed approach has a lower estimation variance than the two-spectral-line approach. The improvement depends on the extent of sampling deviating from the coherent condition, and the best is decreasing variance by 2/7. However, it is also shown that the estimation variance of the windowed IFFT with the Hanning is significantly higher than that of without windowing.

The calculated average gene diversity values ranged from 0.4211 to 0.9590 for DYS438 and DYS385a/b loci, respectively. The discriminatory capacity was 96.77 % with 300 observed haplotypes. Population relationships between Hunan Han and eight other populations available from Y-chromosome haplotype reference database (YHRD) were compared. The results showed that the Han population resided in the Hunan district is significantly different from other populations. Our results also indicated that these 26 Y-STR loci were highly genetically polymorphic in the Hunan Han population and of great value in forensic application.

Previous meta-analysis revealed that mismatch negativity(MMN) amplitude decreased in patients with schizophrenia compared with healthy controls (Cohen's d, d about 1), leading to the possibility of mismatch negativity being used as a biomarker for schizophrenia. However, it is unknown whether MMN is reliably changed in Chinese patients. It is necessary to carry out a meta-analysis on MMN of Han Chinese patients with schizophrenia. To investigate whether MMN could be used as a biomarker for Han Chinese patients with schizophrenia. A literature search was conducted to identify clinical trials on MMN in Han Chinese schizophrenia patients published before May 8, 2017, by searching the Chinese language databases CNKI, WanFang Data, VIP Data and PubMed. The effects of MMN deficits were evaluated for MMN amplitude by calculating standard mean difference (SMDs) between schizophrenia patient groups and healthy control groups. A total of 11 studies were included in the analysis. The total quality of all the studies were more than 6 as evaluated by Newcastle-Ottawa Scale (NOS). Meta-analysis of data from these studies had a pooled sample of 432 patients with schizophrenia and 392 healthy controls. There exists significant MMN deficit in schizophrenia patients compared to healthy controls (Cohen's d =1.004). When studies were excluded due to heterogeneity, the pooled effect size of the MMN differences between the patient group and healthy controls dropped to 0.79 (Cohen's d =0.79). Subgroup analysis showed that MMN amplitude deficits of schizophrenia over three years had the pooled effect size of 0.95, and less than three years had the pooled effect size of 0.77. Publication bias conducted via Egger regression test ( t = 1.83; p = 0.101), suggested that there was no publication bias. The effect size of MMN amplitude between Chinese patients with schizophrenia and healthy controls is consistent with other meta-analyses published on this topic, suggesting that Han Chinese

However, the associations of these loci with HAV or HEV infection in Chinese Han population remain unclear. A total of 3082 Chinese Han persons were included in this study. Anti-HAV IgG and anti-HEV IgG were detected by enzyme-linked immunosorbent assay (ELISA). Genotypes in ABCB1, TGFβ1, XRCC1, APOA4 and APOE SNPs were determined by TaqMan MGB technology. In Chinese Han population, rs1045642 C to T variation in ABCB1 was significantly associated with the decreased risk of HAV infection (P infection in our samples (P C to T variation in APOE was significantly associated with lower risk of HEV infection in males (adjusted OR infection. Additionally, Chinese Han males with rs7412 C to T variation in APOE gene are less prone to be infected by HEV.

Currently, the largest national database within the Y chromosome haplotype reference database (YHRD, https://yhrd.org, release 53) is China, which has approximately 38000 Y chromosomal 17-marker (Yfiler) haplotypes. These haplotype profiles derived from the vast majority of Chinese administrative divisions, but no haplotype data was available for Hubei province, which is located in the Central China region. Herein, 429 unrelated male Chinese Han individuals residing in Hubei province were recruited and genotyped with 17 Y-STR loci. 115 alleles were identified with corresponding allele frequencies spanned from 0.0023 to 07506. The gene diversity (GD) values ranged from 0.3988 at DYS438 to 0.9573 at DYS385a/b. A total of 410 distinct haplotypes were obtained with the overall haplotype diversity (HD) and discrimination capacity (DC) was 0.9995 and 0.9557, respectively. Additionally, genetic relationships along administrative (Han Chinese from different provinces) and ethnic divisions (minority ethnic groups) were analyzed using analysis of molecular variance (AMOVA) tests and visualized by multidimensional scaling plots (MDS). The Han ethnicity including the Hubei Han shows a high genetic homogeneity all across China and significant genetic differences existed between the Hubei Han and some ethnic groups, most prominently for the Kazakhs and the Tibetans.

Han Chinese, Japanese and Korean, the three major ethnic groups of East Asia, share many similarities in appearance, language and culture etc., but their genetic relationships, divergence times and subsequent genetic exchanges have not been well studied. We conducted a genome-wide study and evaluated the population structure of 182 Han Chinese, 90 Japanese and 100 Korean individuals, together with the data of 630 individuals representing 8 populations wordwide. Our analyses revealed that Han Chinese, Japanese and Korean populations have distinct genetic makeup and can be well distinguished based on either the genome wide data or a panel of ancestry informative markers (AIMs). Their genetic structure corresponds well to their geographical distributions, indicating geographical isolation played a critical role in driving population differentiation in East Asia. The most recent common ancestor of the three populations was dated back to 3000 ~ 3600 years ago. Our analyses also revealed substantial admixture within the three populations which occurred subsequent to initial splits, and distinct gene introgression from surrounding populations, of which northern ancestral component is dominant. These estimations and findings facilitate to understanding population history and mechanism of human genetic diversity in East Asia, and have implications for both evolutionary and medical studies.

Full Text Available Aim. To study the correlation between intestinal flora and ulcerative colitis by analyzing the abundance of Bacteroides, Fusobacterium, Clostridium, Bifidobacterium spp., and Faecalibacterium prausnitzii in the intestinal of ulcerative colitis (UC patients and healthy controls with Uygur and Han ethnic. Methods. Bacterial genomic DNA was extracted from fecal samples and analyzed with real-time fluorescence quantitative polymerase chain reaction (PCR to identify the abundance of Bacteroides, Fusobacterium, Clostridium, Bifidobacterium spp., and Faecalibacterium prausnitzii. Results. The samples from UC patients, Uygur and Han ethnic combined, had higher abundance of Bacteroides (P=0.026 but lower Clostridium (P=0.004, Bifidobacterium spp. (P=0.009, and Faecalibacterium prausnitzii (P=0.008 than those from healthy controls. Among UC patients, Bacteroides population was raised in acute UC patients (P≤0.05, while the abundance of Clostridium, Bifidobacterium spp., Fusobacterium, and Faecalibacterium prausnitzii decreased (P≤0.05 compared with the remission. In both UC patients group and control group, no difference was observed in the abundance of these 5 bacteria between the Han and the Uygur group. Conclusions. Variations in the abundance of these five bacterial strains in intestines may be associated with the occurrence of UC in Uygur and Han populations; however, these variations were not associated with ethnic difference.

Several studies have reported STAT4 polymorphism is strongly associated with increased susceptibility to rheumatoid arthritis (RA). However, a study from China showed no association between STAT4 and RA susceptibility in a Chinese Han subpopulation. Since the northern Hans are known to be genetically different from the southern Hans, the aim of this study was to investigate the association of STAT4 polymorphism with RA in a large cohort of a northern Chinese Han subpopulation. 640 RA patients and 662 healthy controls were enrolled. DNA samples were genotyped for STAT4 rs7574865 by direct sequencing. The association of single nucleotide polymorphism (SNP) rs7574865 with RA susceptibility was calculated and the relationship between rs7574865 polymorphism and RA subgroups stratified by clinical features was estimated. We confirmed a significant association of STAT4 rs7574865 polymorphism with RA susceptibility in northern Chinese Han population. The frequency of the minor T allele in RA was significantly higher than in healthy controls (35.2% vs. 31.1%; P = 0.029, OR 1.2 [95% CI 1.02-1.41]). There was also a significant difference in the distribution of the genotypes of SNP rs7574865 between RA patients and healthy controls (P = 0.02). Stratification analyses showed no associations between the genetic risk and clinical/serologic features, but a potential high frequency of TT genotype in a rheumatoid factor-negative subgroup, although it did not reach statistical significance (P = 0.084, OR 2.01 [95% CI 0.91-4.45]). STAT4 rs7574865 is significantly associated with RA susceptibility in northern Chinese Han subpopulations. The genetic differences of Han subpopulations should be considered when genetic susceptibility for diseases is studied. © 2013 The Authors International Journal of Rheumatic Diseases © 2013 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

Population stratification acts as a confounding factor in genetic association studies and may lead to false-positive or false-negative results. Previous studies have analyzed the genetic substructures in Han Chinese population, the largest ethnic group in the world comprising ∼20% of the global human population. In this study, we examined 5540 Han Chinese individuals with about 1 million single-nucleotide polymorphisms (SNPs) and screened a panel of ancestry informative markers (AIMs) to facilitate the discerning and controlling of population structure in future association studies on Han Chinese. Based on genome-wide data, we first confirmed our previous observation of the north-south differentiation in Han Chinese population. Second, we developed a panel of 150 validated SNP AIMs to determine the northern or southern origin of each Han Chinese individual. We further evaluated the performance of our AIMs panel in association studies in simulation analysis. Our results showed that this AIMs panel had sufficient power to discern and control population stratification in Han Chinese, which could significantly reduce false-positive rates in both genome-wide association studies (GWAS) and candidate gene association studies (CGAS). We suggest this AIMs panel be genotyped and used to control and correct population stratification in the study design or data analysis of future association studies, especially in CGAS which is the most popular approach to validate previous reports on genetic associations of diseases in post-GWAS era.

Full Text Available Schizophrenia (SCZ is a severe psychiatric disorder associated with many different risk factors, both genetic and environmental. A recent genome-wide association study (GWAS of Han Chinese identified three single-nucleotide polymorphisms (SNPs rs11038167, rs11038172, and rs835784 in the tetraspanins gene TSPAN18 as possible susceptibility loci for schizophrenia. Hoping to validate these findings, we conducted a case-control study of Han Chinese with 1093 schizophrenia cases and 1022 healthy controls. Using the LDR-PCR method to genotype polymorphisms in TSPAN18, we found no significant differences (P>0.05 between patients and controls in either the allele or genotype frequency of the SNPs rs11038167 and rs11038172. We did find, however, that the frequency of the 'A' allele of SNP rs835784 is significantly higher in patients than in controls. We further observed a significant association (OR= 1.197, 95%CI= 1.047-1.369 between risk for SCZ and this 'A' allele. These results confirm the significant association, in Han Chinese populations, of increased SCZ risk and the variant of the TSPAN18 gene containing the 'A' allele of SNP rs835784.

To investigate whether interleukin-1 alpha (IL1A) and interleukin-1 beta (IL1B) polymorphisms are associated with keratoconus (KC) in unrelated Chinese Han patients. The IL1A (rs2071376) and IL1B (rs1143627, rs16944) polymorphisms were genotyped in 115 unrelated Chinese Han KC patients and 101 healthy Chinese Han volunteers with the Sequenom MassARRAY RS1000. Sequenom Typer 4.0 software, PLINK 1.07, Haploview 4.0 software platform were used to analyze the allelic variants of IL1A and IL1B genes, and their association with KC risk factors were assessed. Among the variants, the three SNPs (rs2071376 in IL1A, rs1143627 and rs16944 in the promoter region of IL1B) were different between the two groups. The A allele of rs2071376 (A > C, p = 0.017, OR = 1.968, 95% C.I. 1.313-3.425), the C allele of rs1143627 (C > T, p rs16944 (A > G, p = 0.002, OR = 2.401, 95% C.I. 1.396-4.161) were associated with a increased risk of KC in Chinese Han patients. This study showed that rs2071376, rs1143627 and rs16944 had significant differences in associations between KC patients and the control group when different genotypes were analyzed in three models (dominant, recessive, and additive). In the haplotype analysis, the two single nucleotide polymorphisms (SNPs), rs1143627 and rs16944 showed strong linkage disequilibrium. In addition, Haplotype "ACA" was found to be associated with a higher risk of developing KC (OR = 12.91, p < 0.001). Keratocyte apoptosis is an initiating event in the pathogenesis of KC which could be induced by the altered levels of IL1 gene. These findings confirmed that polymorphisms in IL1 genes were associated with risk of KC in the Chinese Han population, which help us to gain insight into the pathogenesis of KC.

Objective: To analyze the imaging findings of coronary angiography using 64-slice row CT and investigate the difference of coronary artery's morphological characteristics between Uygur and Han populations. Methods: A retrospective study was made to coronary CT angiographic images of 88 Uygur cases matched with 88 Han cases. The data were analyzed with X 2 test and paired Wilcoxon test. Results: The coronary CT angiographic findings were different between Uygur population and Han population in the following aspects: there were 62, 18, and 8 cases with the left coronary artery originating from intra-sinus, para-sinus and extra-sinus location respectively in Uygur population, while there were 73, 14, and 8 cases in Han population respectively (t=8319, P 2 =5.8381, P 2 =5.1948, P<0.05). The cases with LCA variations were 28 and 49 cases in the two populations respectively (t=2692, P<0.05) and the number with RCA variations were 33 and 27 cases in the two populations respectively (t=968, P<0.05). Conclusions: There are lots of differences of the coronary artery morphology between the Uygur and Han populations. Firstly, these differences may be related to different patterns in coronary angiography. Secondly, these differences may be related to differences between Uygur and Han populations in the incidence and severity of coronary heart disease. (authors)

Xeroderma pigmentosum (XP) is a rare autosomal recessive disorder characterized by extreme sensitivity to sunlight, freckle-like pigmentation and a greatly increased incidence of skin cancers. Genetic mutation detection and genotype-phenotype analysis of XP are rarely reported in the Chinese Han population. To investigate the mutational spectrum of XP in a Chinese Han population, to discover any genotype-phenotype correlation and, consequently, to propose a simple and effective tool for the molecular diagnosis of XP. This study was carried out on 12 unrelated Chinese families that included 13 patients with clinically suspected XP. Genomic DNA was extracted from peripheral blood samples. Mutation screening was performed by direct sequencing of exons and flanking intron-exon boundaries for the entire coding region of eight XP genes. In 12 patients, direct sequencing of the whole coding region of eight XP genes revealed pathogenic mutations, including seven compound heterozygous mutations, three homozygous mutations and a Japanese founder mutation. Thirteen mutations have not been previously identified. This cohort was composed of four patients with XP-C (XPC), two with XP-G (ERCC5), three with XP-A (XPA) and three with XP-V (POLH). This study identified 13 novel mutations and extended the mutation spectrum of XP in the Chinese Han population. In this cohort, we found that patients with XP-G have no neurological symptoms, and patients with XP-A and XP-V have a high incidence of malignancy. Furthermore, lack of stringent protection against sunlight, late diagnosis and long duration of disease play an important role. © 2014 British Association of Dermatologists.

Full Text Available Maintenance of appropriate levels of fecundity is critical for efficient sheep production. Opportunities to increase sheep litter size include identifying single gene mutations with major effects on ovulation rate and litter size. Whole-genome sequencing (WGS data of 89 Chinese domestic sheep from nine different geographical locations and ten Australian sheep were analyzed to detect new polymorphisms affecting litter size. Comparative genomic analysis of sheep with contrasting litter size detected a novel set of candidate genes. Two SNPs, g.71874104G>A and g.71833755T>C, were genotyped in 760 Small Tail Han sheep and analyzed for association with litter size. The two SNPs were significantly associated with litter size, being in strong linkage disequilibrium in the region 71.80–71.87 Mb. This haplotype block contains one gene that may affect litter size, Histone Cell Cycle Regulator (HIRA. HIRA mRNA levels in sheep with different lambing ability were significantly higher in ovaries of Small Tail Han sheep (high fecundity than in Sunite sheep (low fecundity. Moreover, the expression levels of HIRA in eight tissues of uniparous Small Tail Han sheep were significantly higher than in multiparous Small Tail Han sheep (p < 0.05. HIRA SNPs significantly affect litter size in sheep and are useful as genetic markers for litter size.

Full Text Available Existe cada vez más evidencia empírica sobre el hecho de que formar lectores requiere docentes lectores. Por un lado, la relación personal que los docentes mantienen con la lectura influye en el tipo de prácticas de educación lectora que ofrecen en su aula y, por otro, en las creencias que sobre el valor de la lectura mantienen y transmiten a sus estudiantes; esto es, hay una confluencia entre el sujeto lector y el sujeto didáctico que el enseñante es. En este trabajo se ha explorado el potencial que ofrece el estudio de los tres últimos títulos de libros que los futuros maestros y maestras declaran haber leído para comprender parte de su identidad como lectores. La muestra estuvo formada por más de mil estudiantes del último curso de Magisterio de tres universidades públicas. Los resultados revelan que mantienen una relación tibia con la lectura y una motivación extrínseca hacia la práctica lectora: son lectores inmaduros, de libros de moda de gran impacto mediático y de textos prescritos por sus estudios; se analiza también la representación que de la lectura se hacen a través de los títulos evocados. Se concluye acerca de la necesidad de abordar desde su formación inicial como maestros la tarea de reeducar su relación con la lectura.

To estimate the prevalence and associated factors of current infertility for Han, Uygur, and Kazakh ethnicities in Xinjiang rural residents. Chinese Uygur, Kazakh, and Han populations represent > 90% of the total population of the Xinjiang Uygur Autonomous Region, and their customs, culture, and food consumption are different. The effect of ethnic differences on infertility risk factors is rarely studied. A cross-sectional study of 5,086 married and common-law couples, with a female partner aged 18-49, living in Hami, Kuche, or Xinyuan counties in Xinjiang, China. General information for the study subjects, including demographic characteristics, life customs, sexual history, history of contraception use, and history of disease, was collected by questionnaire. General health, gynecologic examinations, and sociodemographic characteristics were also carried out. A total of 5,086 females from Xinjiang Province were surveyed, including 493 with infertility. The standardized prevalence rate of infertility was 9.7% (95% CI 8.9-10.5), and the prevalence of infertility in Han, Uygur, and Kazakh ethnicities was 6.8% (95% CI 5.7-7.9), 10.9% (95% CI 8.0-13.8), and 10.1% (95% CI 7.4-12.8), respectively. The present study suggests that the prevalence of infertility was lower in the Han as compared to the Kazakh and Uygur ethnicities.

CAD (Coronary Artery Disease) is a complex disease that influenced by various environmental and genetic factors. Previous studies have found many single nucleotide polymorphisms (SNPs) associated with the risk of CAD occurrence. However, the results are inconsistent. In this study, we aim to investigate genetic etiology in Chinese Han population by analysis of 7 SNPs in lipid metabolism pathway that previously has been reported to be associated with CAD. A total of 631 samples were used in this study, including 435 CAD cases and 196 normal healthy controls. SNP genotyping were conducted via multiplex PCR amplifying followed by NGS (next-generation sequencing). Rs662799 in APOA5 (Apolipoprotein A5) gene was associated with CAD in Chinese Han population (Odds-ratio = 1.374, P-value = 0.03). No significant association was observed between the rest of SNPs and CAD. Stratified association analysis revealed rs5882 was associated with CAD in non-hypertension group (Odds-ratio = 1.593, P-value = 0.023). Rs1800588 was associated with CAD in smoking group (Odds-ratio = 1.603, P-value = 0.035). The minor allele of rs662799 was the risk factor of CAD occurrences in Chinese Han population.

Multiple genome-wide association studies of primary biliary cirrhosis (PBC) in both European and Japanese ancestries have shown significant associations of many genetic loci contributing to the susceptibility to PBC. Major differences in susceptibility loci between these two population groups were observed. In this study, we examined whether the most significant loci observed in either European and/or Japanese cohorts are associated with PBC in a Han Chinese population. In 1070 PBC patients and 1198 controls, we observed highly significant associations at CD80 (rs2293370, P = 2.67 × 10(-8)) and TNFSF15 (rs4979462, P = 3.86 × 10(-8)) and significant associations at 17q12-21 (rs9303277), PDGFB (rs715505), NF-κB1 (rs7665090), IL12RB2 (rs11209050), and STAT4 (rs7574865; all corrected P values rs7574865) was strongly associated after additional control samples were analyzed. Our study is the first large-scale genetic analysis in a Han Chinese PBC cohort. These results do not only reflect that Han Chinese PBC patients share common genetic susceptibility genes with both their Japanese and European counterparts but also suggest a distinctly different genetic susceptibility profile.

Full Text Available Background Studies on postpartum depression (PPD in China have focused primarily on women of Han ethnicity, whereas work on other ethnic groups has proven limited. This study explored the ethnic differences of associated social-demographic and obstetric factors for PPD between Han-majority and Kazak-minority women in northwestern China. Methods Han and Kazak women who received routine examinations at four hospitals in a multi-ethnic area of China six weeks after childbirth between March 2016 and December 2016 were included in the study. Data on the women’s socio-demographic characteristics, obstetric factors, and possible depression at six weeks after childbirth were collected. We examined the associated factors of PPD using multivariable logistic regression analyses by ethnic group. Results The overall incidence of PPD was 14.6% (184/1,263 at six weeks after childbirth. PPD was detected more frequently among Kazak (16.1% than Han women (13.1%. Kazak women exhibited a higher risk of PPD (adjusted OR = 1.561, 95% CI [1.108–2.198], P = 0.011. Urinary incontinence (UI represented a significant risk factor of PPD for Kazak compared with Han women (OR = 1.720, 95% CI [1.056–2.804], P = 0.003. In contrast, the presence of the mother-in-law as a caregiver after childbirth demonstrated a positive association with PPD among Han (OR = 2.600, 95% CI [1.499–4.512], P = 0.001, but not with Kazak women. Conclusions Kazak women were more likely to develop PPD than Han women, even after controlling for confounders. Moreover, distinct risk factors for PPD existed for Han and Kazak women. Future research that explores the relationships between Han women and their mothers-in-law as well as Kazak women’s attitudes toward UI could help us further understand PPD in these populations.

The purpose of the study was to estimate the chronology of third molar mineralization in Han population of southwestern China and find its unique characteristics so that it would provide a reference in several legal cases like forensic age estimation. The study used Demirjian's staging method to study 2192 orthopantomograms of 984 male and 1208 female subjects aged between 8 and 25 years. The statistical data was analyzed by Student's t test and ANOVA. The conclusions of the study are: (1) The chronological mineralization age of third molars of Han population in Southwestern China is similar to the Turkish and the Japanese, was earlier than the Austrian and Han of South China, but later than the Spanish. (2) The mineralization timing of the third molars between two sides in maxilla or mandible has no significant differences in the same gender group. (3) There is no significant difference in mineralization of third molars between male and female, except for tooth 48 in Demirjian's stage E. (4) The mineralization of third molar in maxilla is earlier than mandible. Copyright © 2014 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

Full Text Available Introduction: HANS KAI is a unique health promotion intervention to improve participants’ health by focussing on interrelated chronic disease prevention behaviours through peer support and strengthening of social support networks. The study objective was to determine the effectiveness of HANS KAI in an urban Canadian setting. Methods: We used a mixed methods intervention research design that involved multiple sites from November 2010 to April 2015. Data was obtained from participant surveys as well as in-person interviews at zero, 6, 12 and 24 months. Participants met in groups at least once a month during the research period, to self-monitor health indicators, prepare and share a healthy snack, participate in a physical activity, set a healthy lifestyle goal (optional and socialize. Results: There were statistically significant mental health improvements from pre- to post-program, and 66% of the participants described specific behaviour changes as a result of HANS KAI participation. Additional positive health impacts included peer support; acquiring specific health knowledge; inspiration, motivation or accountability; the empowering effect of monitoring one’s own health indicators; overcoming social isolation and knowing how to better access services. Conclusion: The need to identify innovative ways to address chronic disease prevention and management has been the driver for implementing and evaluating HANS KAI. While further research will be required to validate the present findings, it appears that HANS KAI may be an effective approach to create environments that empower community members to support each other while promoting healthy lifestyle choices and detecting early changes in health status.

Obituary: Hans Albrecht Bethe, 1906-2005

Wijers, Ralph

2007-12-01

One of the unquestioned giants of physics and astrophysics, Hans Bethe, died on 6 March 2005, at the venerable age of 98, in his home town of Ithaca, New York. Seven decades of contributing to research and a Nobel Prize for his work on stellar hydrogen burning make a listing of his honors superfluous (besides being impossible in this space). Bethe was born in Strassburg, in then German Alsass Lothringen, on 2 July 1906. His father, Albrecht Julius Bethe (1872-1954), taught physiology at the University, and his mother, Anna Kuhn (1876-1966), was a musician and writer. Both his grandfathers were physicians. He spent his youth in Strassburg, Kiel, and Frankfurt, and some time in sanatoria due to tuberculosis. Hans's first scientific paper, at age 18, was with his father and a colleague, on dialysis. His education and early career in Germany brought him into contact with many top stars in the quantum revolution. Starting in Frankfurt in chemistry, Bethe soon switched to physics, taught there by Walter Gerlach and Karl Meissner, among others. In 1926, he successfully applied to join Arnold Sommerfeld's group in Munich, where he met one of his later long-term collaborators, Rudolf Peierls. Bethe considered his entry into physics to have come at an ideal time, with the new ideas of wave mechanics being developed and discussed right there; it was certainly also at an ideal place. His doctoral thesis was on the theory of electron diffraction by crystals, following the experimental work by Clinton Davisson and Lester Germer and the work on X-ray diffraction by Max von Laue and Paul Ewald. The newly minted doctor went from there briefly to Frankfurt and then to Ewald in Stuttgart, where he felt at home academically and personally. In 1939, Bethe would marry Ewald's daughter Rose. Not much later, though, Sommerfeld recalled him to Munich, where Sommerfeld created a Privatdozent position for him. There he worked out the solution for a linear chain of coupled spins by what we

Forensic statistical parameters based on allelic frequencies of commonly used short tandem repeats were estimated for the Han population of Jiangsu province from P.R. China. The 6-dye GlobalFiler™ PCR amplification kit incorporates 21 autosomal STRs, providing reliable DNA typing results with enhanced the power of discrimination. Here, we analyzed the GlobalFiler™ STR loci in 516 unrelated individuals from Jiangsu Han population. A total of 256 alleles were observed ranging between 5 and 35.2 repeat units, and SE33 showed the greatest power of discrimination (34 alleles) in Jiangsu Han population. Most of the loci were found to be in the Hardy-Weinberg equilibrium after the Bonferroni correction with the exception of D3S1358. The combined power of exclusion (CPE) was 0.999999996353609, and the combined match probability (CMP) was 3.64 × 10 -25 . Phylogenetic parameters including pairwise genetic distances showed that Han population living in Jiangsu had closest genetic relationship with other East Asian populations. The present study provides precise reference database for forensic applications and population genetic studies.

Genetic variants at 20p11 confer risk to androgenetic alopecia in the Chinese Han population.

Directory of Open Access Journals (Sweden)

Bo Liang

Full Text Available BACKGROUND: Androgenetic alopecia (AGA is a well-characterized type of progressive hair loss commonly seen in men, with different prevalences in different ethnic populations. It is generally considered to be a polygenic heritable trait. Several susceptibility genes/loci, such as AR/EDA2R, HDAC9 and 20p11, have been identified as being involved in its development in European populations. In this study, we aim to validate whether these loci are also associated with AGA in the Chinese Han population. METHODS: We genotyped 16 previously reported single nucleotide polymorphisms (SNPs with 445 AGA cases and 546 healthy controls using the Sequenom iPlex platform. The trend test was used to evaluate the association between these loci and AGA in the Chinese Han population. Conservatively accounting for multiple testing by the Bonferroni correction, the threshold for statistical significance was P ≤ 3.13 × 10(-3. RESULTS: We identified that 5 SNPs at 20p11 were significantly associated with AGA in the Chinese Han population (1.84 × 10(-11 ≤ P ≤ 2.10 × 10(-6. CONCLUSIONS: This study validated, for the first time, that 20p11 also confers risk for AGA in the Chinese Han population and implicated the potential common genetic factors for AGA shared by both Chinese and European populations.

Full Text Available Background: The present study was designed to compare climacteric symptoms, self-esteem, and quality of life (QOL between women from two different cultures in China (Mosuo and Han Chinese and to evaluate the interaction among these variables. Mosuo is a small ethnic group in southwest China, which is described as a matriarchal society, while Han Chinese is the largest ethnic group with a patriarchal system.Methods: This cross-cultural study was conducted on 54 Mosuo women and 52 Han Chinese women between 40 and 60 years of age. The subjects were selected through convenience sampling. They answered a sociodemographic questionnaire, the Menopause Rating Scale (MRS, the Self-Esteem Scale (SES, and the 12-Item Short Form Health Survey (SF-12.Results: In our sample, Mosuo women obtained lower scores on the psychological and somato-vegetative subscales of the MRS, but higher scores on SES and the mental health-related QOL (SF-12/MCS than Han Chinese women. However, the correlation between climacteric symptoms, self-esteem, and QOL was weaker in the Mosuo group compared to the Han group. Multiple linear regressions indicated that climacteric symptoms have negatively affected women's QOL.Conclusion: In accordance with the study hypothesis, Mosuo women showed milder symptoms, a higher self-esteem, and a better QOL compared to the Han Chinese women during the climacteric. The interaction between climacteric symptoms, psychosocial variables, and QOL revealed cultural differences.

The methodology for the post-closure safety assessment is presented. The assessment context includes regulatory framework (protection principles); scope and time frame; radiological and technical requirements; modeling etc. The description of the Novi Han disposal system contains site location. meteorological, hydrological and seismological characteristics; waste and repository description and human activities characteristics. The next step in the methodology is scenario development and justification. The systematic generation os exposure scenarios is considered as central to the post-closure safety assessment. The most important requirements for the systematic scenario generation approach are: transparency, comprehensiveness (all possible FEPs influencing the the disposal system and the radionuclide release should be considered); relevant future evolutions; identification of critical issues and investigation of the robustness of the system. For the source-pathway-receptor analysis the Process System is divided into near-field, geosphere/atmosphere and biosphere, describing the key facets controlling the potential radionuclide migration to the environment. The schematic division of the Novi Han near-field Process System into lower-level conceptual features is presented and discussed. As a result of the examinations of the FEPs three classes of scenarios are identified for the Novi Han post-closure safety assessment: Environmental evolution scenarios (geological change and climate change); future human action scenarios (human intrusion and archaeological action); Scenarios with very low probability (terrorism, crashes, explosions). The safety assessment iteration leads to identification of a modern scenario generation approach, assessment of key radionuclide releases, geological and hydrological evaluation, identification of the key parameters from sensitivity analysis etc. Examples of conceptual models are given. For the mathematical modeling the AMBER code is used

Full Text Available Abstract Background The deafness-associated gene mutation profile varies greatly among regions and races. Due to the multi-ethnic coalition of over one thousand years, non-syndromic deafness (NSD patients of Uyghur ethnicity may exhibit a unique deafness-associated gene mutation spectrum as compared to Han Chinese deaf population. Methods In order to characterize nine loci of four deafness-associated genes of Uyghur NSD patients in comparison with Chinese Han deaf population, NSD patients (n = 350 were enrolled, including Uyghur (n = 199 and Han Chinese (n = 151. Following the history taking, blood samples were collected for DNA extraction. DNA microarray was performed on nine loci of four deafness-associated genes, including 35delG, 176-191del16, 235delC, 299-300delAT, 538C > T, 1555A > G, 1494C > T, 2168A > G, and IVS7-2A > G. The samples that showed the absence of both wild and mutant probe signals were tested for further DNA sequencing analysis. Results The mutations in the nine loci of prevalent deafness-associated genes were detected in 13.06% of Uyghur NSD patients and 32.45% of Han Chinese patients (P GJB2 mutation was detected in 9.05% of Uyghur patients and 16.56% of Han Chinese patients (P > 0.05, respectively. 235delC was the hotspot mutation region in NSD patients of the two ethnicities, whereas 35delG was the mutation hotspot in Uyghur patients. 187delG mutation was detected for the first time in Uyghur NSD patients and considered as an unreported pathological variant of GJB2. SLC26A4 mutation was found in 2.01% of Uyghur patients and 14.57% of Han Chinese patients (P P > 0.05, respectively. The NSD patients exhibited a low frequency of GJB3 mutation regardless of ethnicity. Conclusion Prevalent deafness-associated gene mutations in the nine loci studied were less frequently detected in Uyghur NSD patients than in Han Chinese patients. GJB2 was the most common mutant gene in the two ethnicities, whilst the two ethnicities differed

We analyzed haplotypes for 24 Y chromosomal STRs (Y-STRs), including 17 Yfiler loci (DYS19, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DY438, DYS439, DYS448, DYS456, DYS458, DYS635 and Y-GATA-H4) and 7 additional STRs (DYS388, DYS444, DYS447, DYS449, DYS522 and DYS527a/b) in 1100 unrelated Chinese Han individuals from Henan Province using AGCU Y24 STR kit systems. The calculated average gene diversity (GD) values ranged from 0.4105 to 0.9647 for the DYS388 and DYS385a/b loci, respectively. The discriminatory capacity (DC) was 72.91% with 802 observed haplotypes using 17 Yfiler loci, by the addition of 7 Y-STRs to the Yfiler system, the DC was increased to 79.09% while showing 870 observed haplotypes. Among the additional 7 Y-STRs, DYS449, DYS527a/b, DYS444 and DYS522 were major contributors to enhancing discrimination. In the analysis of molecular variance, the Henan Han population clustered with Han origin populations and showed significant differences from other Non-Han populations. In the present study, we report 24 Y-STR population data in Henan Han population, and we emphasize the need for adding additional markers to the commonly used 17 Yfiler loci to achieve more improved discriminatory capacity in a population with low genetic diversity.

Situated in the central part of China, the Han River Basin is undergoing rapid social and economic development with some human interventions to be made soon which will profoundly influence the water environment of the basin. The integrated MIKE 11 model system comprising of a rainfall-runoff model (NAM), a non-point load evaluation model (LOAD), a hydrodynamic model (MIKE 11 HD) and a water quality model (ECOLab) was applied to investigate the impact of the Middle Route of the South-North Water Diversion Project on the Han River and the effectiveness of the 2 proposed mitigation projects, the 22 wastewater treatment plants (WWTPs) and the Yangtze-Han Water Diversion Project. The study concludes that business as usual will lead to a continuing rapid deterioration of the water quality of the Han River. Implementation of the Middle Route of the South-North Water Diversion Project in 2010 will bring disastrous consequence in the form of the remarkably elevated pollution level and high risk of algae bloom in the middle and lower reaches. The proposed WWTPs will merely lower the pollution level in the reach by around 10%, while the Yangtze-Han Water Diversion Project can significantly improve the water quality in the downstream 200-km reach. The results reveal that serious water quality problem will emerge in the middle reach between Xiangfan and Qianjiang in the future. Implementation of the South-North Water Diversion Project (phase II) in 2030 will further exacerbate the problem. In order to effectively improve the water quality of the Han River, it is suggested that nutrient removal processes should be adopted in the proposed WWTPs, and the pollution load from the non-point sources, especially the load from the upstream Henan Province, should be effectively controlled.

Hemoglobin concentration at high altitude is considered an important marker of high altitude adaptation, and native Tibetans in the Qinghai-Tibetan plateau show lower hemoglobin concentrations than Han people who have emigrated from plains areas. Genetic studies revealed that EPAS1 plays a key role in high altitude adaptation and is associated with the low hemoglobin concentration in Tibetans. Three single nucleotide polymorphisms (rs13419896, rs4953354, rs1868092) of noncoding regions in EPAS1 exhibited significantly different allele frequencies in the Tibetan and Han populations and were associated with low hemoglobin concentrations in Tibetans. To explore the hereditary basis of high altitude polycythemia (HAPC) and investigate the association between EPAS1 and HAPC in the Han population, these 3 single nucleotide polymorphisms were assessed in 318 male Han Chinese HAPC patients and 316 control subjects. Genotyping was performed by high resolution melting curve analysis. The G-G-G haplotype of rs13419896, rs4953354, and rs1868092 was significantly more frequent in HAPC patients than in control subjects, whereas no differences in the allele or genotype frequencies of the 3 single nucleotide polymorphisms were found between HAPC patients and control subjects. Moreover, genotypes of rs1868092 (AA) and rs4953354 (GG) that were not observed in the Chinese Han in the Beijing population were found at frequencies of 1.6% and 0.9%, respectively, in our study population of HAPC patients and control subjects. Carriers of this EPAS1 haplotype (G-G-G, rs13419896, rs4953354, and rs1868092) may have a higher risk for HAPC. These results may contribute to a better understanding of the pathogenesis of HAPC in the Han population. Copyright © 2014 Wilderness Medical Society. Published by Elsevier Inc. All rights reserved.

To describe and compare the prevalence and characteristics of dry eye among Han and Uyghur persons living in Kashi, the most inland city of China. A total of 1015 residents of Kashi participated in this 2013 cross-sectional study. To evaluate clinical characteristics, each subject completed (1) a dry-eye questionnaire detailing symptoms of dry eye, (2) Schirmer's I-test (SIT), (3) tear-film break-up time (BUT) test, and fluorescein staining of the cornea. Dry eye was defined as the existence of dry eye symptoms and at least two positive clinical signs. Data were analyzed using SPSS software. The prevalence and risk factors of dry eye were evaluated using a multivariate model. Overall, 282 (27.8%) of the 1015 participants were diagnosed with dry eye (95% confidence interval (CI): range, 25.5-30.1). The prevalence of dry eye among Han persons (37.9 %) (95% CI: range, 35.8-40.0) was higher than that among Uyghurs (21.8%) (95% CI: 19.6-24.0) (p dry eye was 25.6% (95% CI: range, 23.3-27.8) among men and 28.7% (95% CI: 26.5-30.9) among women (p > 0.05). Risk factors for dry eye included ethnicity, age, occupation, arthritis, and dry mouth. Our study revealed a higher prevalence of dry eye among Han than Uyghur persons in Kashi. Dry eye was significantly associated with environment and ethnicity.

Objectives To investigate whether levels of blood pressure and fasting glucose differ among Chinese children of three different ethnicities (i.e., Uyghurs, Kazakhs and Hans) and whether the differences are explained by childhood obesity. Methods A school-based cross-sectional study was conducted in a large three ethnic pediatric population (n=6,633), whose ages ranged from 7–18 years. Anthropometrics and blood pressure were measured using standard protocols. Fasting glucose was measured in a subset of children (n=2,295) who were randomly selected based on ethnicity and age. The age-sex stratified Chinese national cutoffs were used to define obesity and high blood pressure (HBP). The prevalence of HBP, impaired fasting glucose (IFG), mean levels of blood pressure and glucose were compared among three ethnic groups. Results 2,142 Uyghurs, 2,078 Han and 1,997 Kazakhs were analyzed. After adjusting for age and body mass index (BMI), the mean blood pressure for Uyghurs was on average, 2–4 mmHg lower than those for Hans and Kazakhs. Kazakhs had the lowest mean fasting glucose compared with Hans and Uyghurs (4.5 vs 5.0 vs. 4.8mmol/L, respectively). The differences in blood pressure and fasting glucose persisted even after adjusting for age and BMI, and the differences among ethnic groups in blood pressure levels and fasting glucose levels were observed as early as 7 to 9 years of age. Conclusions The prevalence of HBP and IFG differed significantly among Uyghurs, Hans and Kazakhs, and the ethnic differences observed in childhood were consistent with those observed in adults from the same region. While childhood obesity is a significant risk factor for hypertension and elevated glucose, the differences among ethnic groups were not explained by obesity alone. PMID:24904957

Vitiligo is an immune-related disease with patchy depigmentation of skin and hair caused by selective destruction of melanocytes. In recent decades, many studies have shown the association between vitiligo and HLA genes; however, the results of Han Chinese are scarce. In this study, we performed a fine-mapping analysis of the MHC region in 2818 Han Chinese subjects through a widely used HLA imputation method with a newly built large-scale Han-MHC reference panel. Three new four-digit HLA alleles (HLA-DQB1 ∗ 02:02, HLA-DQA1 ∗ 02:01 and HLA-DPB1 ∗ 17:01) were identified to be associated with the risk of vitiligo, and four previously reported alleles were confirmed. Further conditional analysis revealed that two important variants, HLA-DQβ1 amino acid position 135 (OR = 1.79, P = 1.87 × 10 -11 ) and HLA-B amino acid positions 45-46 (OR = 1.44, P = 5.61 × 10 -11 ), conferred most of the MHC associations. Three-dimension ribbon models showed that the former is located within the β2 domain of the HLA-DQβ1 molecule, and the latter lies in the α1 domain of the HLA-B molecule, while both are involved in specific antigen presenting process. Finally, we summarized all significant signals in the MHC region to clarify their complex relationships, and 8.60% of phenotypic variance could be explained based on all reported variants in Han Chinese so far. Our findings highlight the complex genetic architecture of the MHC region for vitiligo in Han Chinese population and expand our understanding of the roles of HLA coding variants in the etiology of vitiligo.

To determine whether mitochondrial DNA (mtDNA) variations are associated with schizophrenia, 313 patients with schizophrenia and 326 unaffected participants of the northern Chinese Han population were included in a prospective study. Single-nucleotide polymorphisms (SNPs) including C5178A, A10398G, G13708A, and C13928G were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Hypervariable regions I and II (HVSI and HVSII) were analyzed by sequencing. The results showed that the 4 SNPs and 11 haplotypes, composed of the 4 SNPs, did not differ significantly between patient and control groups. No significant association between haplogroups and the risk of schizophrenia was ascertained after Bonferroni correction. Drawing a conclusion, there was no evidence of an association between mtDNA (the 4 SNPs and the control region) and schizophrenia in the northern Chinese Han population.
Debating Modernity as Secular Religion: Hans Kelsen’s futile exchange with Eric Voegelin

This article reviews the mysterious and recently published last book by Hans Kelsen, “Secular Religion. A Polemic Against the Misinterpretation of Modern Social Philosophy, Science and Politics as ‘New Religions’”, contextualizing it with reference to the little known dialogue between Hans Kelsen...... and Eric Voegelin. The confrontation between Kelsen and Voegelin, two of the most illustrious émigré scholars who found in America their new home, is important to revisit because it touches upon several axes of debate of crucial importance to postwar intellectual history: the religion/secularity debate......, the positivist/anti-positivist debates, and the controversy that also led to the famous Voegelin/Arendt debate: how to read the horrors of totalitarianism into a historical trajectory of modernity. Although the Kelsen/Voegelin exchange ended in failure and bitterness its substance matter goes to the heart...

This cross-cultural study aimed to compare climacteric symptoms, self-esteem, and perceived social support between Mosuo and Han Chinese women, and to explore the interaction between culture and climacteric symptoms. Mosuo is a Chinese minority group with a matriarchal structure, and Han Chinese is the majority ethnic group in China with a patriarchal structure. Through convenience sampling, 54 Mosuo women and 52 Han Chinese women between 40 and 60 years of age completed the sociodemographic questionnaire, the Menopause Rating Scale, the Self-Esteem Scale, and the Perceived Social Support Scale. Compared with Han Chinese women, Mosuo women scored lower on the psychological (P psychological symptoms severity. Referring to the severity of all symptoms, predictive variables were: perceived support from family (β = -0.210, P = 0.017); self-esteem (β = 0.320, P Cultural variables such as familial structure, women's self-esteem, and perceived social support were correlated with symptomatology.

Acompanhado o desenvolvimento de sua teoria da modernidade e das conseqüências dessa teoria para a escrita da história e para a auto-consciência disciplinar. Por fim, proponho uma releitura da história da historiografia através dos dois tipos de culturas propostas por Gumbrecht, ou seja, culturas de sentido e culturas de presença. Argumento que mesmo que a historiografia moderna possa ser caracterizada como predominantemente ancorada na produção de sentido, aspectos centrais de sua história só podem ser explicados através de elementos típicos da produção de presença.This paper analyses some historiographical aspects of Hans Ulrich Gumbrecht's work, particularly his theory of modernity and its consequences to the writing of history and its disciplinary self-conscious. Finally, it is proposed a reinterpretation of the history of historiography based on the distinction between cultures of presence and cultures of meaning. It is argued that despite the fact that the elements of meaning are predominant in the constitution of modern historiography, the forces acting in its constitution cannot be explained without typical elements of a culture of presence.

To understand the epidemiological characteristics and distribution of mild cognitive impairment (MCI) in elderly populations from Mongolian and Han nationalities living in the pastoral areas of Inner Mongolia Autonomous Region of China. According to the MCI clinical diagnostic criteria from Diagnostic and Statistical Manual of Mental Disorders 4th revised edition (DSM-IV) by American Psychiatric Association, the individuals under study were at the age of 55 or over, with Mongolian or Han ethnicities and living in the pastoral area of Inner Mongolia. The crude MCI morbidity rates of Mongolian and Han of the study populations in the pastoral area of Inner Mongolia Autonomous Region of China was 19.48% (1782/9146) and the standardization morbidity was 18.98%. The crude MCI morbidity rates of both Mongolian and Han ethnicities were 17.46% (the standardization morbidity was 16.99%) and 20.60% (the standardization morbidity was 19.98%), respectively. There showed a significant positive correlation between the crude morbidities and age, also significantly increasing with the latter. In the Mongolian population, the morbidity increased from 12.17% at the age 55-59 to 27.78% at 85 while in the Han population, the morbidity increased from 15.50% at the age 55-59 to 23.53% at 85. In both the populations of Mongolian and Han, there was a statistically difference found between the morbidities of MCI (χ2=13.229, P=0.000). The morbidity was higher in Hans than in the Mongolians. However, there was no statistically significant difference noticed between the morbidities of MCI in the Mongolian males and females (χ2=2.376, P=0.123). There was statistically significant difference found between the morbidities of MCI in the Han males and females, with females having higher risk than males (χ2=24.470, P=0.000). The morbidity of MCI in the elderly Mongolian and Han populations from the pastoral area of Inner Mongolia Autonomous Region of China was considered to be quite high and

Reported isolation rates of Malassezia yeast from human skin show geographic variations. In China, the populations of the Han (1,182.95 million) and Tibetan (5.41 million) ethnic groups are distributed over 9.6 and 3.27 million square kilometers respectively, making biodiversity research feasible and convenient. Malassezia furfur clinical strains (n = 29) isolated from different individuals, with or without associated dermatoses, of these two ethnic groups (15 Han and 12 Tibetan) were identified and analyzed with DNA fingerprinting using single primers specific to minisatellites. Using the Bionumerics software, we found that almost all M. furfur clinical isolates and type strains formed five distinct group clusters according to their associated skin diseases and the ethnic groups of the patients. These findings are the first to focus on the genetic diversity and relatedness of M. furfur in the Tibetan and Han ethnic groups in China and reveal genetic variation associated with related diseases, host ethnicity and geographic origin.

Es así, que para lograr visibilizar dichos saberes se recurrió a la mirada arqueológica –genealógica, donde se realizó el rastreo de algunos documentos institucionales e investigativos, las charlas con cinco maestros en torno a su ser y quehacer y el análisis de los anteriores elementos desde la relación sujeto, saber y poder. Con base en lo anterior, se encontró que en la escuela circulan algunos saberes relacionados con la Botánica, los cuales son trabajados desde aspectos taxonómicos y netamente Biológicos. Además, de visibilizarse que en las instituciones educativas y maestros con los que se trabajó conciben la enseñanza de la Botánica, se como un pretexto que contribuye a desarrollar determinadas competencias científicas en la escuela.

We aim to assess the prevalence, awareness, treatment, control, and related risk factors of hypertension among urban adults in Inner Mongolia, with the comparison of the differences between Mongolian and Han populations in this respect. Methods Three thousand two hundred fifty-one individuals aged 20–80 years (2326 Han and 925 Mongolian were selected using a multistage cluster sampling method from Inner Mongolia in 2014. The adjusted prevalence, awareness, treatment and control of hypertension were evaluated by the Logistic regression. In addition, possible interactions were also tested. When interactions were found significant, strata-specific analysis were performed. Multivariate logistic regression was used for estimating independent associations between risk factors and hypertension. Results The prevalence of hypertension was 27.47 % for Han population, 31.46 % for Mongolian population. The adjusted prevalence, awareness, treatment and control of hypertension were 26.45, 65.43, 78.24 and 48.28 % in Han, and 31.30, 68.22, 85.57 and 50.55 % in Mongolian, respectively. There was no significant difference in the adjusted awareness, treatment and control of hypertension among Mongolian and Han adult residents (all P >0.05. Lower prevalence of hypertension was associated with younger age and healthy weight in both Mongolian and Han adults. Within Han adults, high education, moderate physical activity and non-alcohol drinkers were additionally associated with lower prevalence of hypertension, whereas within Mongolian adults, lower prevalence was associated with being female. Among residents with medium education level, nondrinkers had 0.60 times lower odds of having hypertension than current drinkers (OR = 0.60, 95 % CI: 0.44–0

Human neutrophil antigen 3 (HNA-3) is encoded by the SLC44A2 gene. Antibodies against HNAs can cause severe, often fatal, transfusion reactions, known as transfusion-related acute lung injury, and neonatal neutropenia. We explored the 2 common HNA-3 variants in 9 ethnic populations residing in Sichuan and Yunnan provinces of China as compared to the Han population. We genotyped for SLC44A2 (rs2288904) by polymerase chain reaction sequence-based typing among blood donors, for a total of 2206 individuals in Yunnan and 376 in Sichuan. The SLC44A2*02 allele (HNA-3b antigen) frequency varied between 0.24 and 0.33 for all 9 ethnic populations in Yunnan, including Zhuang, Derung, Hani, Lisu, Bai, Miao, Dai, Naxi, and Yi. Specifically, the Yi ethnicity did not present an unusually great SLC44A2*02 frequency at any of the 4 locations examined in Yunnan. Except of the Yi ethnicity in Sichuan (0.40), the Han ethnicity, as the majority population group, had the greatest SLC44A2*02 frequency with 0.39 in Yunnan and 0.35 in Sichuan. The ethnic populations in Southwest China are not at an increased risk for anti-HNA3a compared to the Han population, with the possible exception of Yi in Sichuan. Our data, however, corroborated the known high prevalence of SLC44A2*02 in Han populations. Hence, the Han populations in Yunnan, Sichuan and elsewhere in China are at a comparatively great risk for developing HNA-3a antibodies.

Identification of rare deafness genes for inherited congenital sensorineural hearing impairment remains difficult, because a large variety of genes are implicated. In this study we applied targeted capture and next-generation sequencing to uncover the underlying gene in a three-generation Han family segregating recessive inherited hearing loss and retinitis pigmentosa. After excluding mutations in common deafness genes GJB2, SLC26A4 and the mitochondrial gene, genomic DNA of the proband of a Han family was subjected to targeted next-generation sequencing. The candidate mutations were confirmed by Sanger sequencing and subsequently analyzed with in silico tools. An unreported splice site mutation c.3924+1G > C compound with c.6028G > A in the MYO7A gene were detected to cosegregate with the phenotype in this pedigree. Both mutations, located in the evolutionarily conserved FERM domain in myosin VIIA, were predicted to be pathogenic. In this family, profound sensorineural hearing impairment and retinitis pigmentosa without vestibular disorder, constituted the typical Usher syndrome type 2. Identification of novel mutation in compound heterozygosity in MYO7A gene revealed the genetic origin of Usher syndrome type 2 in this Han family. Copyright © 2016 Elsevier Ireland Ltd.

Full Text Available Abstract Background Several common genetic polymorphisms in the low density lipoprotein receptor (LDL-R gene have associated with modifications of serum total cholesterol (TC and low density lipoprotein cholesterol (LDL-C levels, but the results are not consistent in different populations. Bai Ku Yao is a special subgroup of the Yao minority in China. The present study was undertaken to detect the association of LDL-R gene Ava Ⅱ polymorphism and serum lipid levels in the Guangxi Bai Ku Yao and Han populations. Methods A total of 1024 subjects of Bai Ku Yao and 792 participants of Han Chinese were randomly selected from our previous stratified randomized cluster samples. Genotyping of the LDL-R gene Ava Ⅱ polymorphism was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing. Results The levels of serum TC, high density lipoprotein cholesterol (HDL-C, LDL-C, apolipoprotein (Apo A1 and the ratio of ApoA1 to ApoB were lower in Bai Ku Yao than in Han (P - and A+ alleles was 65.5% and 34.5% in Bai Ku Yao, and 80.7% and 19.3% in Han (P -A-, A-A+ and A+A+ genotypes was 42.6%, 45.9% and 11.5% in Bai Ku Yao, and 64.9%, 31.6% and 3.5% in Han (P P 3.20 mmol/L subgroups in Bai Ku Yao (P P P P +A+ genotype had higher serum LDL-C, TC, HDL-C or ApoA1 levels than the subjects with A-A+ and A-A- genotypes. Spearman rank correlation analysis revealed that the levels of LDL-C in Bai Ku Yao and HDL-C in Han were correlated with genotypes (P P Conclusions The association of LDL-R gene Ava Ⅱ polymorphism and serum lipid levels is different between the Bai Ku Yao and Han populations. The discrepancy might partly result from different LDL-R gene Ava Ⅱ polymorphism or LDL-R gene-enviromental interactions.

Hypertension is highly prevalent in low-income population. This study aims to investigate ethnic disparities in hypertension and identify modifiable factors related to its occurrence and control in developing regions in South China. Blood pressure was measured in the Bouyei and Han populations during a community-based health survey in Guizhou, 2012. A multistage stratified sampling method was adopted to recruit Bouyei and Han aged from 20 to 80 years. Taking mixed effects into consideration, multilevel logistic models with random intercept were used for data analysis. The prevalence rates of hypertension were 35.3% for the Bouyei and 33.7% for the Han. Among the hypertensive participants, 30.1% of the Bouyei and 40.2% of the Han were aware of their hypertensive conditions, 19.7% of the Bouyei and 31.1% of the Han were receiving treatment, and only 3.6% of the Bouyei and 9.9% of the Han had their blood pressure under control. Age-sex standardized rates of awareness, treatment, and control were consistently lower in the Bouyei than the Han. Such ethnic disparities were more evident in the elderly population. Avoidance of excessive alcohol consumption and better education were favorable lifestyle for reduction in risk of hypertension. Moderate physical activity improved control of hypertension in Bouyei patients under treatment. Conclusively, hypertension awareness, treatment, and control were substantially lower in Bouyei than Han, particularly in the elderly population. Such ethnic disparities indicate that elderly Bouyei population should be targeted for tailored interventions in the future.

Exploration of the ethnic origin and genetic differentiation of 56 Chinese officially recognized nationalities populations played a fundamental role in the research field of population genetics, forensic science, linguistics, anthropology, and archaeology. In the present study, population data of 21 autosomal STR loci (CSF1PO, D10S1248, D12S391, D13S317, D16S539, D18S51, D19S433, D21S11, D2S1338, D2S441, D3S1358, D5S818, D6S1043, D7S820, D8S1179, FGA, Penta D, Penta E, TH01, TPOX, and vWA) included in the AGCU EX22 kit in 2793 Southwest Han Chinese individuals was obtained and population genetic relationships among 28 Chinese populations were investigated. Our study indicated that the twenty-one autosomal STRs are highly polymorphic in the Sichuan Han population and can be used as a powerful tool in the routine forensic usage. MDS and phylogenetic analysis suggested that the Sichuan Han population kept a close genetic relationship with the southwest populations. Copyright © 2017 Elsevier B.V. All rights reserved.

Natural organic matter (NOM) from the Han River, Korea was fractionated into humic and non-humic fractions by absorbing onto XAD-7HP, and these fractions were analyzed using UV-absorption, and for dissolved organic C (DOC). The humic fraction (i.e. humic substances; HS) was extracted and its characteristics were compared to commercial humic materials using various spectroscopic methods such as Fourier transform infrared (FT-IR), proton nuclear magnetic resonance ( 1 H-NMR) and fluorescence spectroscopy. The humic fraction as organic C was 47.0% on the average, however, a rainfall event brought a higher humic fraction into Han River water. The molar ratios of H/C and O/C in the HS from Han River water (HRHS) were 1.40 and 0.76, respectively, and the ratio of aliphatic to aromatic protons in the HS (P Al /P Ar ratio) was 5.8. Aromaticity and humification degree (i.e., degree of condensation) of HRHS were relatively lower than those from other humic materials, while the portion of oxygenated functional groups was relatively higher. FT-IR, 1 H-NMR and fluorescence spectroscopy showed distinct differences between HRHS and the commercial humic materials. Commercial humic materials are not representative of HS extracted from Han River water. The fluorescence spectra, relatively simple measurements, were found to be most useful as fingerprints for humic materials from particular sources

To evaluate the incidence of dyslipidemia among Uygur and Han patients with impaired fasting glucose (IFG). To investigate the influence factors on LDL-c in this population. This cross-sectional study included a total of 4709 participants, consisting of Uygurs patients (n=2053) and Han patients (n=2656) from Xinjiang province, who were screened for diabetes mellitus. A stratified multistage sampling design was used to collect the participants. The influence factors on LDL-c were analyzed by Logistic regression analysis. Among the IFG patients (n=1757), Uighur IFG group had a higher prevalence of dyslipidemia than that of Han IFG group, 99.8% vs. 63.7%, Pdifference in the Han groups. Logistic regression analysis revealed that risk factors associated with LDL-c were age, total cholesterol and 2 h postprandial blood glucose for the Uighur IFG patients. However, gender and total cholesterol were risk factors for Han IFG patients. Uighur IFG patients had higher incidence of dyslipidemia than that of Han IFG patients. For Uyghur IFG patients, closing follow-up of total cholesterol and 2 h postprandial blood glucose were necessary. As to the Han IFG patients, we should pay more attention to male and total cholesterol in order to lower LDL-c levels. So, appropriately preventive and therapeutic measures should be chosen based on the characteristics of abnormal lipid profiles in different nationality.

Full Text Available Objective The objective of this study was to compare the DNA methylation profile in the longissimus dorsi muscle between Small Tailed Han and Dorper×Small Tailed Han crossbred sheep which were known to exhibit significant difference in meat-production. Methods Six samples (three in each group were subjected to the methylated DNA immunoprecipitation sequencing (MeDIP-seq and subsequent bioinformatics analyses to detect differentially methylated regions (DMRs between the two groups. Results 23.08 Gb clean data from six samples were generated and 808 DMRs were identified in gene body or their neighboring up/downstream regions. Compared with Small Tailed Han sheep, we observed a tendency toward a global loss of DNA methylation in these DMRs in the crossbred group. Gene ontology enrichment analysis found several gene sets which were hypo-methylated in gene-body region, including nucleoside binding, motor activity, phospholipid binding and cell junction. Numerous genes were found to be differentially methylated between the two groups with several genes significantly differentially methylated, including transforming growth factor beta 3 (TGFB3, acyl-CoA synthetase long chain family member 1 (ACSL1, ryanodine receptor 1 (RYR1, acyl-CoA oxidase 2 (ACOX2, peroxisome proliferator activated receptor-gamma2 (PPARG2, netrin 1 (NTN1, ras and rab interactor 2 (RIN2, microtubule associated protein RP/EB family member 1 (MAPRE1, ADAM metallopeptidase with thrombospondin type 1 motif 2 (ADAMTS2, myomesin 1 (MYOM1, zinc finger, DHHC type containing 13 (ZDHHC13, and SH3 and PX domains 2B (SH3PXD2B.

Shortly before the outbreak of World War I, the so-called Elberfeld horses, the counting and speaking animals, were among the most debated subjects of the newborn comparative psychology. Yet, they have left little trace in the historiography of this discipline, mostly as an appendix of the more famous Clever Hans. Their story is generally told as the prelude to the triumph of reductionistic experimental psychology. By paying a more scrupulous attention than has so far being done to the second life of Hans, and to the endeavours of his second master, Karl Krall, this article explores the story of the Elberfeld horses as an important, if so far neglected, chapter in the history of experimental parapsychology.

Full Text Available Abstract Background Rapid socioeconomic development resulting in changing lifestyles and life expectancy appears to be accompanied by an increasing prevalence of type 2 diabetes. Genetic predisposition related to ethnicity is a major determinant of diabetes risk. This study investigates the prevalences of diabetes and prediabetes in different ethnic populations residing in the Mudanjiang area located in the northeast of China. Methods A cross-sectional survey was carried out among Han, Manchu and Korean Chinese aged 20 years or older. Diabetes and prediabetes were diagnosed using standard oral glucose tolerance tests. Results The prevalence of diabetes in Manchu (8.39% and Korean Chinese (9.42% was significantly lower than that in Han (12.10%. The prevalence of prediabetes was 18.96%, 19.36% and 20.47% in Han, Manchu and Korean populations, respectively. Korean Chinese had a lower prevalence of isolated impaired fasting glucose and higher prevalence of isolated impaired glucose tolerance than the other two ethnic groups. Most patients with diabetes, especially ethnic minority patients, were undiagnosed. A multiple logistic regression analysis showed that age, family history of diabetes, control of diet, self-monitoring of weight, central obesity, increased heart rate, hypertension, elevated plasma triglyceride level, elevated plasma low-density lipoprotein cholesterol, and Han ethnicity were significantly associated with an increased risk of diabetes. Further, Manchu Chinese were found to have the lowest risk of diabetes. Conclusions Our study indicates that diabetes is a major public health problem in the Mudanjiang area of China. Ethnicity plays a role in the different prevalences of diabetes and prediabetes among the three ethnic groups. Diabetes is less prevalent among Manchu Chinese compared with Han and Korean Chinese.

However, most studies examining dyslexia have been skewed toward Western countries, and few have considered two nationalities simultaneously. This study focused on differences in dyslexia prevalence and potential environmental risk factors between Han and Uyghur children. A cross-sectional study was conducted in Kashgar and Aksu, cities in Xinjiang province, China. A two-stage sampling strategy was used to recruit 2,854 students in grades 3-6 from 5 primary schools in 5 districts; 2,348 valid student questionnaires were included in the analysis. Dyslexia checklists for Chinese and Uyghur children and pupil rating scales were used to identify children with dyslexia. Questions related to the home literacy environment and reading ability were used to evaluate potential environmental risk factors. Single factor analysis and multivariate logistic regression were used to examine prevalence and risk factors for dyslexia. Dyslexia prevalence differed significantly between Han (3.9%) and Uyghur (7.0%) children (P dyslexia prevalence between Han and Uyghur children could have occurred because of factors such as mother's occupation (P = 0.02, OR = 0.04, 95% CI = 0.01-0.68) and the frequency with which parents told stories (P = 0.00, OR = 4.50, 95% CI = 1.67-12.11). The prevalence of dyslexia was high in all children, particularly those in the Uyghur group. Environmental factors could have been responsible for some of the differences observed. The results contribute to the early identification and management of dyslexia in children from these two groups and research examining developmental dyslexia and differences in racial genetics.

Karunasagar, D.; Bhikshamaiah, G.; Keshavulu Goud, M.; Lacha Goud, S.

In the presence of defocusing the modified Sparrow limits of resolution for two-line objects have been investigated for a diffraction-limited coherent optical system apodized by generalized Hanning amplitude filters. These limits have been studied as a function of different parameters such as intensity ratio, the order of the filter for various amounts of apodization parameter. Results reveal that in some situations the defocusing is effective in enhancing the resolution of an optical system.

Background Complete blood count (CBC) reference intervals are important to diagnose diseases, screen blood donors, and assess overall health. However, current reference intervals established by older instruments and technologies and those from American and European populations are not suitable for Chinese samples due to ethnic, dietary, and lifestyle differences. The aim of this multicenter collaborative study was to establish CBC reference intervals for healthy Han Chinese adults. Methods A total of 4,642 healthy individuals (2,136 males and 2,506 females) were recruited from six clinical centers in China (Shenyang, Beijing, Shanghai, Guangzhou, Chengdu, and Xi’an). Blood samples collected in K2EDTA anticoagulant tubes were analyzed. Analysis of variance was performed to determine differences in consensus intervals according to the use of data from the combined sample and selected samples. Results Median and mean platelet counts from the Chengdu center were significantly lower than those from other centers. Red blood cell count (RBC), hemoglobin (HGB), and hematocrit (HCT) values were higher in males than in females at all ages. Other CBC parameters showed no significant instrument-, region-, age-, or sex-dependent difference. Thalassemia carriers were found to affect the lower or upper limit of different RBC profiles. Conclusion We were able to establish consensus intervals for CBC parameters in healthy Han Chinese adults. RBC, HGB, and HCT intervals were established for each sex. The reference interval for platelets for the Chengdu center should be established independently. PMID:25769040

Full Text Available Nitric oxide (NO is an important messenger molecule and effector molecule. This study aimed to investigate the relation of neuronal nitric oxide synthase (nNOS gene polymorphism with ischemic stroke in Han Chinese of North China. This was a case-control study. A total of 413 patients with ischemic stroke were recruited from Han Chinese of North China. There were 201 males and 212 females. In addition, 477 healthy subjects served as controls including 224 males and 253 females. Multiplex SNaPshot was employed to detect nNOS gene polymorphism (rs2293050, rs2139733, rs7308402, and rs1483757. Results showed that the rs1483757, rs2139733, and rs2293050 genotypes and allele frequencies were comparable between patients and controls. However, ischemic stroke patients had significantly reduced AG genotype and A allele frequency when compared with controls (P=0.037, P=0.041. After adjusting confounding factors (gender, age, smoking, history of drinking, hypertension, and diabetes, AG genotype and A allele were still related to ischemic stroke (OR=0.572, 95% CI: 0.335–0.978, P=0.041; OR=0.611, 95% C: 0.378–0.985, and P=0.041 and both were found to be protective factors. Our results showed that rs7308402 gene polymorphism of nNOS is related to ischemic stroke in Han Chinese of North China.

Following the economic development and the progress of urbanization, the damage on water pollution has been more serious but a social cost caused by water pollution cannot be measured. Although the need of water quality preservation is emphasized, a base material for public investment on enhancing water quality preservation is not equipped yet due to the absence of economic values of water resource. Therefore it measured a cost generated by leaving pollution not treated water quality in this study. To measure the usable value of water resource or the cost of water pollution all over the country should include a national water system, but this study is limited on the mainstream of Han River water system from North Han River through Paldang to Chamsil sluice gates. Further study on Nakdong River and Keum River water systems should be done. 74 refs., 4 figs., 51 tabs.

Full Text Available With the rapid development of hydropower exploitation in China, changes in runoff and sediment transport have become a significant issue that cannot be neglected. In this study, the Han River was selected as a study case, where the runoff variation and changes in sediment load at the Baihe, Huangjiagang, Huangzhuang, and Xiantao stations were analyzed in different time periods. The results indicate that impact of cascade hydropower exploitation on runoff and sediment transport is significantly different even during the same time periods. After reservoir regulation, the decreasing of sediment load is faster than that of runoff. Strong positive correlation between runoff and sediment load exists during different time periods, while reservoir operation leads to different turning points at the Baihe, Huangjiagang, Huangzhuang, and Xiantao stations in the middle and lower Han River. As a key driving factor, runoff variation contributed to sediment transport with different impact index CR. The impact index CR before and after the first change point at the Baihe, Huangjiagang, Huangzhuang, and Xiantao stations is 43.35%, −3.68%, 11.17%, and 30.12%, respectively. This study helps us understand and evaluate the hydrological changes under cascade hydropower exploitation in the middle and lower Han River.

Full Text Available The sheep intestinal tract is characterized by a diverse microbial ecosystem that is vital for the host to digest diet material. The importance of gut microbiota (GM of animals has also been widely acknowledged because of its pivotal roles in the health and well-being of animals. However, there are no relevant studies on GM of small-tail Han sheep, a superior mutton variety domestic in China. In this study, the structure and distribution of gut microflora were studied by high-throughput sequencing technology. Results showed a significant difference between jejunum and cecum, jejunum, and rectum. Meanwhile, the cecum and rectum not only display higher species richness but also exhibit higher similarity of the bacterial diversity than that of the jejunum based on the results of abundance-based coverage estimator (ACE, Chao1, and Shannon indexes. Firmicutes and Bacteroidetes were the predominant phyla in cecum and rectum, while higher relative abundances of Firmicutes and Cyanobacteria were observed in jejunum. At the genus level, Bacteroidetes, Ruminococcus, Lactobacillus, Flavonifractor, and Clostridium were the dominant genera in the cecum and rectum. An obvious dynamic distribution of Lactobacillus is continuously decreasing from the jejunum to the cecum, then to the rectum, whereas the result of Bacteroides is completely inverse. In addition, this study also found many kinds of bacteria associated with the production of volatile fatty acids (VFA colonized in the large intestine. This study is the first to investigate the distribution of intestinal flora in small-tail Han sheep. The findings provide an important indication for diagnosis and treatment of intestinal diseases in small-tail Han sheep, as well as offer a direction for the development of intestinal microecological preparations.

Sodium taurocholate co-transporting polypeptide (NTCP) plays an important role in the enterohepatic circulation of bile acids. Recently, NTCP was identified as a hepatitis B virus (HBV) receptor. The aim of this study is to investigate the association of NTCP polymorphisms with HBV clinical outcomes and investigate the relationship between NTCP polymorphisms and the serum bile acid level in a Chinese Han population. The single nucleotide polymorphisms rs2296651 and rs4646285 were genotyped in 1619 Chinese Han individuals. Improved multiple ligase detection reaction was utilized to genotype. The level of bile acids was measured by the enzymatic cycling method. Quantitative polymerase chain reaction analysis was carried out to analyze the potential function. In logistic regression analysis, the frequency of rs2296651 (S267F) CT genotype was higher in HBV immune recovery and healthy control groups than in the chronic HBV infection group (P = 0.001 and P HBV infection group (P = 0.011). No difference in serum bile acid was detected between the rs4646285 wild-type patients and mutant-type patients. Quantitative reverse transcription-polymerase chain reaction showed the NTCP mRNA levels were lower in rs4646285 variants than wild types. NTCP gene polymorphisms may be associated with the natural course of HBV infection in a Chinese Han population. The S267F variant may be a protective factor to resist chronic hepatitis B progression which showed a higher bile acid level in Chinese Han chronic HBV infection patients. The rs4646285 variants could influence the expression of NTCP at the level of transcription, and ultimately may be associated with HBV infection immune recovery. © 2017 The Japan Society of Hepatology.
[Hans Gross and the beginning of criminology on a scientific basis].

2007-01-01

Modern criminology--if one wants to consider it a separate scientific discipline at all--is usually perceived as being mainly influenced by the methods of natural sciences supplemented by components from the field of psychology, which, at least in some of its conceptions, tends to define itself as a natural science, too. If we take a look at the history of science, we will see development of criminology in this direction was not necessarily inevitable. The scientific work of the Austrian Hans Gross (1847-1915), one of the founding fathers of scientific criminology, serves as an example of the way how natural sciences and their exact methods became established in the methodological apparatus of modern criminology, although in praxi his claim for the application of exact methods was all too often replaced by irrational and intuitive ways of working. Still, Hans Gross' fundamental decision for the exact methods derived from the natural sciences is an important step towards a criminology that can be understood as a part of natural sciences, largely superseding the methods of cultural sciences and anthropological philosophy. This approach made the (criminal) human being an object of measurement and can result in the concept of man as a mere phenomenon of quantity. This is, on the one hand, ethically questionable; on the other hand, it made modern criminology more efficient and successful.

Durer, following the advice of his protector Pirckheimer, elaborated the drawings for Horapollo’s Hieroglyphica, published by Professor George Boas. This visual and semantic vocabulary, of great importance in the History of Art from the Renaissance onward, and specifically in Durer’s graphic art, is evident in the carvings for the Triumphal Arch of Maximilian (1515, studied by Panofsky.

This study characterized the genetic variations of mitochondrial DNA (mtDNA) to elucidate the maternal genetic structure of Liaoning Han Chinese. A total of 317 blood samples of unrelated individuals were collected for analysis in Liaoning Province. The mtDNA samples were analyzed using two distinct methods: sequencing of the hypervariable sequences I and II (HVSI and HVSII), and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the coding region. The results indicated a high gene diversity value (0.9997 ± 0.0003), a high polymorphism information content (0.99668) and a random match probability (0.00332). These samples were classified into 305 haplotypes, with 9 shared haplotypes. The most common haplogroup was D4 (12.93%). The principal component analysis map, the phylogenetic tree map, and the genetic distance matrix all indicated that the genetic distance of the Liaoning Han population from the Tibetan group was distant, whereas that from the Miao group was relatively close.

Full Text Available Abstract Background Copy number variations (CNVs have recently been recognized as important structural variations in the human genome. CNVs can affect gene expression and thus may contribute to phenotypic differences. The copy number inferring tool (CNIT is an effective hidden Markov model-based algorithm for estimating allele-specific copy number and predicting chromosomal alterations from single nucleotide polymorphism microarrays. The CNIT algorithm, which was constructed using data from 270 HapMap multi-ethnic individuals, was applied to identify CNVs from 300 unrelated Han Chinese individuals in Taiwan. Results Using stringent selection criteria, 230 regions with variable copy numbers were identified in the Han Chinese population; 133 (57.83% had been reported previously, 64 displayed greater than 1% CNV allele frequency. The average size of the CNV regions was 322 kb (ranging from 1.48 kb to 5.68 Mb and covered a total of 2.47% of the human genome. A total of 196 of the CNV regions were simple deletions and 27 were simple amplifications. There were 449 genes and 5 microRNAs within these CNV regions; some of these genes are known to be associated with diseases. Conclusion The identified CNVs are characteristic of the Han Chinese population and should be considered when genetic studies are conducted. The CNV distribution in the human genome is still poorly characterized, and there is much diversity among different ethnic populations.

PATIENTS: A total of 700 patients (324 male and 376 female; mean age = 40±14.9 years with depression who met the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV and 673 healthy controls (313 male and 360 female; mean age = 41.9±17.2 years were used to investigate the relationship between SNPs of NPY and the pathogenesis of MDD. A total of 417 patients (195 male and 202 female; mean age = 36±14.2 years diagnosed with MDD and 314 healthy controls (153 male and 161 female; mean age = 37.9±14.2 years from Chinese Han population were used to verify the relationship between SNPs of NPY and the pathogenesis of MDD. INTERVENTION AND OUTCOME: Ligase detection reactions were performed to detect the SNP sites of NPY. A series of statistical methods was carried out to investigate the correlation between the NPY gene SNP and MDD. RESULTS: Statistical analysis showed a significant correlation between the SNP sites rs16139 in NPY and the morbidity of depression. Patients with MDD have a lower frequency of A-allele in rs16139 in replicate samples from Chinese Han population. However, the frequency varied between male and female patients. CONCLUSION: The gene polymorphism loci rs16139 was closely related to MDD in Chinese Han population.

Objective: By the preliminary comparison study on the constituent ratio and clinical characteristics of polycystic ovary syndrome (PCOS) in Tibetan and Han women in Tibetan Plateau, we aimed to find the relevance of its pathogenic factors, and to guide the treatment of PCOS in the plateau region and improve the prognosis. Methods: The general situation and clinical data of 165 patients who were diagnosed with PCOS from December 1, 2015 to November 30, 2016 in the Department of Obstetrics and Gynecology of the People's Hospital of Tibet Autonomous Region were analyzed retrospectively. The prevalence of PCOS among Tibetan and Han women in Tibetan Plateau were compared. Results: (1) A total of 1 520 patients were treated in the Tibet Autonomous Region People's Hospital gynecological endocrinology clinics in one year (Tibetan 865 cases, Han 617 cases, other ethnic groups 38 cases), of which patients with PCOS accounted for 10.9% (165/1520). (2) The incidence of Tibetan PCOS patients with oligomenorrhea, infertility, amenorrhea, acne, hairy, LH/FSH inverted, overweight (BMI≥24), and waist circumference >80 cm were 21.2% (35/165), 20.6% (34/165), 16.4% (27/165), 28.5% (47/165), 17% (28/165), 38.2% (63/165), 23.6% (39/165), and 36.4% (60/165), respectively. The incidence of Han PCOS patients with oligomenorrhea, infertility, amenorrhea, acne, hairy, LH/FSH inverted, overweight (BMI≥24), and waist circumference >80 cm were 7.9% (13/165), 10.3% (17/165), 9.1% (15/165), 15.2% (25/165), 9.7% (16/165), 14.5% (24/165), 10.9% (18/165) and 19.4% (32/165), respectively.

His ideas were adopted by Qin Shihuang, the so-called First Emperor, who unified China and unleashed a despotic régime characterized by the crackdown of any political debate and the suppression of free speech. The connexion between rhetorical development and the political sphere in the context of Classical China’s last stage may set the scene for a wider discussion about that link.

Full Text Available Progress and decline: historical dialect in two texts by Hans Magnus Enzensberger The interpretation of history as a process of dialectical development has been one of the most important ideas of Marxist philosophy. Whereas earlier Marxists optimistically considered this process as steering inevitably towards a sociopolitical utopia, subsequent thinkers in the Marxist tradition, especially those identified as Neo-Marxists (like Theodor Adorno, had a more pessimistic interpretation of dialectics. Influenced especially by Adorno, German poet and social commentator Hans Magnus Enzensberger uses the concept of “historical dialectics” as a seminal theme in two of his literary works: “Mausoleum: siebenunddreißig Balladen aus der Geschichte des Fortschritts” and “Der Untergang der Titanic”. In these two texts the representation of the ambiguity of “Fortschritt” or historical development presupposes a more pessimistic account of the historical process. This ambiguity is present both in a bird’s-eye view of the historical process (“Mausoleum”, and in the focus on one specific historical incident (“Der Untergang der Titanic”. Enzensberger subsequently continues to consider the role of art within this dialectical context. In this article, both Enzensberger’s literary use of the philosophical concept of historical dialectics and its artistic implications (as identified by him are examined.

To observe the clinical efficacy of electroacupuncture (EA) on mild cognitive impairment (MCI) for patients of Uygur and Han nationality and explore the national diversity among the patients with MCI. Twenty-five cases were divided into Han nationality group (15 cases) and Uygur nationality group (10 cases) according to patient's nationality. In either group, EA was applied to Baihui (GV 20), Fengchi (GB 20), Xuanzhong (GB 39), Fuliu (KI 7), Sanyinjiao (SP 6) and Taixi (KI 3), once per day, 15 treatments made one session and there were 5 days at the interval among the sessions. Totally, 3 sessions of treatment were required. The proton magnetic resonance spectroscopy (1H-MRS) was used to observe the changes in the ratio of N-acetylaspartate and creatine (NAA/Cr) on the left hippocampus for the patients in two groups before and after treatment as well as the changes in the results of the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) separately. NAA/Cr in Uygur nationality group was higher than that in Han nationality group before treatment (1.659 +/- 0.418 vs 1.137 +/- 0.190, P NAA/Cr on the left hippocampus in either group was up-regulated as compared with that before treatment (both P < 0.01). EA can improve the overall cognitive function for the patients with MCI. There is the national diversity in the partial brain metabolite level between Uygur patients and Han patients with MCI.

Full Text Available The variations of SORCS1 gene may play potential key roles in late-onset Alzheimer's disease (LOAD. To evaluate the relationship between the polymorphism of SORCS1 gene and LOAD in the ethnic Han Chinese, we conducted a case-control study to investigate the association between the single-nucleotide polymorphisms (SNPs in intron 1 of SORCS1 and LOAD in Chinese Han population. Six reported SNPs in intron 1 of SORCS1 were analyzed by Snapshot, genotyping and haplotyping in 236 Chinese LOAD cases and 233 matched controls. The significant differences in frequencies of two SNPs (rs10884402, rs950809 were found between the two groups. In addition, haplotype analyses revealed that, in the LOAD group, the frequency of haplotypes C-C-G-T-C (alleles in order of rs17277986, rs6584777, rs10884402, rs7078098, rs950809 polymorphisms were significantly higher (Psim<0.0001 while haplotype C-C-A-T-C, C-C-A-C-C, T-T-A-C-C were significantly lower (Psim<0.0001. Our data suggested that the genetic variation of the rs10884402 and rs950809 in intron 1 of SORCS1 was associated with the late-onset AD in the Chinese Han population.

Full Text Available The highest developed form of a spatial concept of ainn in the urban area of the Ottoman period is the rectangular form of the spatial organization of the hans from the 15th and the 16th centuries. The most important examples are Kurshumlihan, Sulihan and Kapan han in the old bazaar in Skopje, which are part of a complex spatial system of the historical part of the city. According to the urban concept of the Ottoman builders, a group of public buildings has been formed, where mosque, bedesten, hamam, etc. appear beside another. Spatial analysis of auxiliary rooms and overnight accommodation, or open spaces (atrium, porch has a certain specific ratio. The experience of the organization from historical buildings is a valuable experience in terms of balancing different contents of the used space, its purpose and adjustment to the current needs of the object. The experiences from the study of certain spatial elements of the hans and from the analysis of the current tourism development in which they are included, can be applied in the concept of modern tourist objects.

This article discusses three of the problems that the German philosopher Hans Jonas studied. The first one addresses the need for a specific ethic dedicated to the moral dimension of environmental problems, from a different perspective to the traditional. The second problem is crucial in the discussion on environmental ethics: the value of the nature. Does the nature have an intrinsic value or an instrumental value only (to satisfy the interests of the human being)? The thesis of Jonas, which claimed that nature is a good in itself, were further elaborated here. And the third problem is the derivation of moral norms and the role of man in this ethic that recognizes a good in itself in nature. According to Jonas, the human being is not diminished by recognizing the intrinsic value of nature, since the man's uniqueness and value are unquestionable. From these three central issues, the paper highlights the importance of seeking the links between bioethics and environmental ethics to address the current environmental, social and economic crisis.
Earthquakes as collapse precursors at the Han-sur-Lesse Cave in the Belgian Ardennes

Collapse activation is an ongoing process in the evolution of karstic networks related to the weakening of cave vaults. Because collapses are infrequent, few have been directly observed, making it challenging to evaluate the role of external processes in their initiation and triggering. Here, we study the two most recent collapses in the Dôme chamber of the Han-sur-Lesse Cave (Belgian Ardenne) that occurred on or shortly after 3rd December 1828 and between the 13th and 14th of March 1984. Because of the low probability that the two earthquakes that generated the strongest ground motions in Han-sur-Lesse since 1800, on 23rd February 1828 (Mw = 5.1 in Central Belgium) and 8th November 1983 (Mw = 4.8 in Liège) occurred by coincidence less than one year before these collapses, we suggest that the collapses are related to these earthquakes. We argue that the earthquakes accelerated the cave vault instability, leading to the collapses by the action of other factors weakening the host rock. In particular, the 1828 collapse was likely triggered by a smaller Mw = 4.2 nearby earthquake. The 1984 collapse followed two months of heavy rainfall that would have increased water infiltration and pressure in the rock mass favoring destabilization of the cave ceiling. Lamina counting of a stalagmite growing on the 1828 debris dates the collapse at 1826 ± 9 CE, demonstrating the possibility of dating previous collapses with a few years of uncertainty. Furthermore, our study opens new perspectives for studying collapses and their chronology both in the Han-sur-Lesse Cave and in other karstic networks. We suggest that earthquake activity could play a stronger role than previously thought in initiating cave collapses.

Responsibility to Nature? Hans Jonas and Environmental Ethics

Peter Wolsing

2013-11-01

Full Text Available This paper presents the philosopher Hans Jonas’s idea of an environmental ethics. Through an outline of the development of man’s relation to nature from Greek antiquity to the present it is argued that science and technology in modernity favour a relation of exploitation which is partly the cause of fatal climate changes. Through Jonas’s philosophical notion of an ontology of man as an alternative to classical dualism and by means of a turn to an ontological interpretation of Kant’s categorical imperative, it is argued that mankind has a responsibility to both coming generations and to the biosphere as a whole. Not only does this ontological shift from philosophy of mind to an ontology of man transcend dualism in philosophy, it throws a new critical light on the technological development and suggests a new way of considering man’s place in the cosmos.

Full Text Available In 2012 an unpublished book by the Austrian legal philosopher Hans Kelsen, Secular Religion, has been posthumously published. This book, written by Kelsen between 1952 and 1964 in the United States, severely criticizes those theories of politics and culture that misinterpret modern social philosophy, science and politics as new religions, mainly adopting the controversial concept of “secular religión.” In the first part of the paper, we reconstruct the genesis of the book and the complex events that led to its final version, and we underline the motives that led Kelsen to write this vehement polemic in defense of the spirit of modernity, and eventually to withdraw it. In the second part of the paper, we investigate some of the main methodological and theoretical contributions that this work, albeit its critical tenor, is able to give to an anthropology of modernity.

In 1931 two pharmaceutical drawers containing mineral specimens, belonging to Sir Hans Sloane, the 18th century collector, Royal Physician, President of the Royal Society and of the Royal College of Physicians of London, were found in the Department of Botany of the Natural History Museum (NHM) of London. The drawers, each divided into 49 compartments, contained a total of 107 mineral pharmaceutical specimens, some labelled as mercury or white arsenic. Their registration, identification with the Sloane Manuscript Catalogues and subsequent transfer to the Mineralogy department of the NHM where one of these drawers is now on public display, had been documented by 1935. In antiquity therapeutic empiricism attributed medicinal properties to animal products, plants and minerals, including the soil of specific geographic locations. This communication traces the medicinal use of certain earths and minerals, listed in Sir Hans Sloane's manuscript catalogues, to classical antiquity with a reference to Arsenic compounds, which in our time are finding application in the treatment of acute promyelocytic leukaemia and to Terra Lemnia, a celebrated antidote of repute spanning twenty centuries, also included in the Sloane collections.

Obstructive sleep apnea syndrome (OSAS) is a common health problem that is associated with abnormality in craniofacial morphology. The growth hormone receptor (GHR) belongs to the cytokine receptor superfamily and mediates the majority of growth hormone signaling, which, among other functions, determines mandibular growth and development. The aim of this study was to determine if correlations exist between single nucleotide polymorphisms (SNPs) in the GHR gene and OSAS in the Han or Hani ethnic groups in China. A total of 274 Han subjects (106 with OSAS and 168 without OSAS) and a total of 270 Hani subjects (64 with OSAS and 206 without OSAS) were enrolled in our study. Genomic DNA was extracted from peripheral blood obtained from all subjects. Genotyping was undertaken for eight SNPs in the GHR gene (rs3756416, rs7727047, rs2910875, rs12153009, rs2972781, rs12518414, rs4410646, and rs6451620) using PCR amplification and Sanger sequencing. The genotype frequency of rs12518414 was associated with OSAS in both the Han and Hani groups, and the A allele frequency was remarkably lower in Hani OSAS patients compared with Hani controls (16.7 vs 29.9%). In addition, the G allele frequency of the rs3756416 SNP was significantly lower in OSAS patients compared with normal controls in the Hani ethnic group (12.5 vs 24.6%). In a comparison between ethnic groups, genotype frequencies of four SNPs (rs2972781, rs6451620, rs12518414, and rs7727047) differed between Han and Hani OSAS patients, with the A allele frequency of the rs12518414 and G allele frequency of the rs7727047 were significantly higher in the Han OSAS patients. In conclusion, significant associations were detected between some SNPs in the GHR gene and OSAS occurrence while others appeared to be ethnicity-dependent.

A present limitation of forensic anthropology practice in China is the lack of population-specific criteria on contemporary human skeletons. In this study, a sample of 203 maxillofacial Cone beam computed tomography (CBCT) images, including 96 male and 107 female cases (20-65 years old), was analyzed to explore mandible sexual dimorphism in a population of contemporary adult Han Chinese to investigate the potential use of the mandible as sex indicator. A three-dimensional image from mandible CBCT scans was reconstructed using the SimPlant Pro 11.40 software. Nine linear and two angular parameters were measured. Discriminant function analysis (DFA) and logistic regression analysis (LRA) were used to develop the mathematics models for sex determination. All of the linear measurements studied and one angular measurement were found to be sexually dimorphic, with the maximum mandibular length and bi-condylar breadth being the most dimorphic by univariate DFA and LRA respectively. The cross-validated sex allocation accuracies on multivariate were ranged from 84.2% (direct DFA), 83.5% (direct LRA), 83.3% (stepwise DFA) to 80.5% (stepwise LRA). In general, multivariate DFA yielded a higher accuracy and LRA obtained a lower sex bias, and therefore both DFA and LRA had their own advantages for sex determination by the mandible in this sample. These results suggest that the mandible expresses sexual dimorphism in the contemporary adult Han Chinese population, indicating an excellent sexual discriminatory ability. Cone beam computed tomography scanning can be used as alternative source for contemporary osteometric techniques. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

To investigate the genetic cause of the patients with non-syndromic enlarged vestibular aqueduct (EVA) but without bi-allelic SLC26A4 mutations. Presence of a homozygous genomic deletion was detected in a Chinese Han deaf patient (D1467-1) who failed to amplify the first three exons of SLC26A4. The breakpoints of the deletion were fine-mapped and revealed by PCR amplification and sequencing. This deletion was subsequently screened in 22 Chinese Han EVA probands with mono-allelic SLC26A4 mutations. The possible founder effect of the newly identified genomic deletion was evaluated by haplotype analysis. A homozygous c.-2071_307+3801del7666 deletion of SLC26A4 was identified in patient D1467-1. This novel genomic deletion was subsequently identified in 18% (4/22) of the Chinese Han EVA probands with mono-allelic SLC26A4 mutations. Haplotype analysis showed that this genomic deletion is likely a founder mutation in Chinese Hans. Our results suggested that the cryptic c.-2071_307+3801del7666 deletion of SLC26A4 is relatively frequent in Chinese Han non-syndromic EVA patients without bi-allelic SLC26A4 mutations. Screening of this genomic deletion should be incorporated into the routine DNA testing of SLC26A4 in Chinese Hans. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

We analyzed the genetic polymorphisms of 15 autosomal and 10 Y-chromosomal STR loci in 214 individuals of Han population from Southern Shaanxi of China and studied the genetic relationships between Southern Shaanxi Han and other populations. We observed a total of 150 alleles at 15 autosomal STR loci with the corresponding allelic frequencies ranging from 0.0023 to 0.5210, and the combined power of discrimination and exclusion for the 15 autosomal STR loci were 0.99999999999999998866 and 0.999998491, respectively. For the 10 Y-STR loci, totally 100 different haplotypes were obtained, of which 94 were unique. The discriminatory capacity and haplotype diversity values of the 10 Y-STR loci were 0.9259 and 0.998269, respectively. The results demonstrated high genetic diversities of the 25 STR loci in the population for forensic applications. We constructed neighbor-joining tree and conducted principal component analysis based on 15 autosomal STR loci and conducted multidimensional scaling analysis and constructed neighbor-joining tree based on 10 Y-STR loci. The results of population genetic analyses based on both autosomal and Y-chromosome STRs indicated that the studied Southern Shaanxi Han population had relatively closer genetic relationship with Eastern Han population, and distant relationships with Croatian, Serbian and Moroccan populations.

The physician Hans Reiter as prisoner of war in Nuremberg: a contextual review of his interrogations (1945-1947).

Crimes against humanity by Nazi Germany led to the codification of procedures for trying medical professionals. The principles detailed in the Nuremberg Code formulated by the Allies represented their effort to prevent future excesses and embody today's Institutional Review Boards. Reactive arthritis is often termed Reiter's syndrome, after Hans Reiter, who was incarcerated at Nuremberg. The authors reviewed Dr Hans Reiter's Nuremberg file at the National Archives in Washington, DC, and present chronologic excerpts of his interrogations between 1945 and 1947, with interpretative commentary. Reiter was involved with or knowledgeable of involuntary sterilization and euthanasia undertaken by the Nazi regime. He also played an active role in the design of a study that inoculated concentration camp internees at Buchenwald with an experimental typhus vaccine, which resulted in hundreds of deaths. A brilliant investigator and erudite intellectual, the career of Hans Reiter shows the importance and the relevance of scientific inquiry to adhere to principles enumerated in the Nuremberg Code. Because he was not the first to describe reactive arthritis, and in view of the above, Reiter's syndrome should only be used to cite an older reference that uses the term or in a historical context.

P-Glycoprotein (P-gp, encoded by MDR1 gene) plays an important role in determining bioavailability and pharmacologic effects of many drugs. There is increasing evidence that P-gp activity may be genetically determined. In this study, we investigated the genotype distribution and the haplotype profiles of MDR1 gene in Chinese Han, Bai, Wa and Tibetan subjects. Much lower frequencies of the 1236T allele and the 2677T allele were found in Wa subjects than those in other three ethnic groups, while the 2677A allele was found about 6-fold more frequently in Han subjects than in subjects of other three ethnic groups. The Han, Bai and Tibetan subjects share the same three predominant haplotypes (T-T-T, T-G-C and C-G-C), and T-T-T is the highest and accounts for more than one third of the number of haplotypes in the subjects from each ethnic group. However, T-T-T was less common than T-G-C, T-G-T and C-G-C and occurring at only 13.8% in Wa subjects, furthermore, higher frequencies of T-G-T, C-T-C, C-G-T and C-T-T were observed in Wa subjects compared to those in other three ethnic groups. Frequencies of C-A-C and T-A-C in Han subjects were higher than those in other three ethnic groups. The findings of this study will be of some relevance in predicting MDR1 phenotype and pharmacokinetics as well as pharmacodynamic effects of many commonly used drugs that are P-gp substrates in these four Chinese ethnic groups.

The aim of this experiment was to study the effects of pen size and parity on maternal behaviour of twin-bearing Small-Tail Han ewes. A total of 24 ewes were allocated to a 2×2 design (six per pen), with parity (primiparous or multiparous) and pen size (large: 6.0×3.0 m; small: 6.0×1.5 m) as main effects at Linyi University, Shandong Province, China. Behaviour was observed from after parturition until weaning. All ewes were observed for 6 h every 5 days from 0700 to1000 h and from 1400 to 1700 h. Continuous focal animal sampling was used to quantify the duration of maternal behaviours: sucking, grooming and following as well as the frequency of udder accepting, udder refusing and low-pitched bleating. Oestradiol and cortisol concentrations in the faeces (collected in the morning every 5 days) were detected using EIA kits. All lambs were weighed 24 h after parturition and again at weaning at 35 days of age. The small pen size significantly reduced following (Pbehaviour in sheep during lactation. The study is also the first to report on the maternal behaviour of Chinese native sheep breeds (Small-Tail Han sheep), with implications for the production of sheep in China.

Full Text Available Abstract Background Monoamine oxidases (MAOs catalyze the metabolism of dopaminergic neurotransmitters. Polymorphisms of isoforms MAOA and MAOB have been implicated in the etiology of mental disorders such as schizophrenia. Association studies detected these polymorphisms in several populations, however the data have not been conclusive to date. Here, we investigated the association of MAOA and MAOB polymorphisms with schizophrenia in a Han Chinese population. Methods Two functional single nucleotide polymorphisms (SNPs, rs6323 of MAOA and rs1799836 of MAOB, were selected for association analysis in 537 unrelated schizophrenia patients and 536 healthy controls. Single-locus and Haplotype associations were calculated. Results No differences were found in the allelic distribution of rs6323. The G allele of rs1799836 was identified as a risk factor in the development of schizophrenia (P = 0.00001. The risk haplotype rs6323T-rs1799836G was associated with schizophrenia in female patients (P = 0.0002, but the frequency difference was not significant among male groups. Conclusions Our results suggest that MAOB is a susceptibility gene for schizophrenia. In contrast, no significant associations were observed for the MAOA functional polymorphism with schizophrenia in Han Chinese. These data support further investigation of the role of MAO genes in schizophrenia.
Quality assurance for safety in the radioactive waste management: a quality assurance system in Novi Han radioactive waste repository

Novi Han Radioactive Waste Repository (RWR) is still the only place in Bulgaria for storage of low and intermediate level radioactive waste. It is necessary to establish and maintain a Quality Assurance (QA) system to ensure that the RWR can be operated safely with regard to the health and safety of the general public and site personnel. A QA system has to establish the basic requirements for quality assurance in order to enhance nuclear safety by continuously improving the methods employed to achieve quality. It is envisaged that the QA system for the Novi Han RWR will cover the operation and maintenance of the radioactive waste disposal facilities, the radiation protection and monitoring of the site, as well as the scientific and technology development aspects. The functions of the Novi Han RWR presume the availability of an environmental management system. It is appropriate to establish a QA system based on the requirements of the ISO Standards 9001 and 14000, using the recommendations of the IAEA (Quality assurance for safety in NPPs and other nuclear installations, code and safety guides Q1-Q14).

Suicide attempts at the Han river are rapidly increasing, which are 4.11 times from 2005 to 2015, whereas the rate of completed suicide in South Korea increased 1.07 times during the same period. However, few studies have been conducted on the issue because many suicide attempters were seriously injured after a fall in the Han river. We present a case of a patient with major depressive disorder (MDD) who attempted suicide and minimally injured after jumping from the bridge at the Han river. We could assess his psychological and neurocognitive functions before and immediately after his attempt. From this case, we can identify that higher cognitive aspect of executive dysfunction, especially in the frontal domain of selective attention and inhibition, may be associated with his suicide attempt. In conclusion, we suggest psychiatric treatments for cognitive impulsiveness and safety barriers at the bridge to prevent suicide attempts of patients with MDD.

Esophageal cancer is the sixth most common cancer worldwide. Esophageal squamous cell carcinoma (ESCC) is a fatal malignancy associated with low 5-year survival rate. The aim of this study was to assess the association between methylenetetrahydrofolate reductase (MTHFR) tagging single nucleotide polymorphisms (SNPs) rs1801133 C>T, rs3753584 A>G, rs4845882 G>A, rs4846048 A>G and rs9651118 T>C genotypes and ESCC susceptibility in a hospital-based case-control study. We conducted genotyping analyses for these five SNPs with 629 ESCC cases and 686 controls in a Chinese Han population. Ligation detection reaction method was used to identify genotypes of these MTHFR SNPs. Our results demonstrated that MTHFR rs1801133 C>T was associated with the risk of ESCC; however, MTHFR rs4845882 G>A and rs4846048 A>G SNPs were associated with the decreased risk of ESCC, and MTHFR rs3753584 A>G and rs9651118 T>C SNPs were not associated with ESCC risk. Our findings suggests that MTHFR rs1801133 C>T, rs4845882 G>A and rs4846048 A>G SNPs may be genetic modifiers for developing ESCC in Chinese Han population.

Full Text Available Prof. Hans Georg Trüper, one of the most important scientists in the field of halophile research, passed away on 9 March 2016 at the age of 79. I here present a brief obituary with special emphasis on Prof. Trüper’s contributions to our understanding of the halophilic prokaryotes and their adaptations to life in hypersaline environments. He has pioneered the study of the halophilic anoxygenic phototrophic sulfur bacteria of the Ectothiorhodospira—Halorhodospira group. Some of the species he and his group isolated from hypersaline and haloalkaline environments have become model organisms for the study of the mechanisms of haloadaptation: the functions of three major organic compounds – glycine betaine, ectoine, and trehalose – known to serve as “compatible solutes” in halophilic members of the Bacteria domain, were discovered during studies of these anoxygenic phototrophs. Prof. Trüper’s studies of hypersaline alkaline environments in Egypt also led to the isolation of the first known extremely halophilic archaeon (Natronomonas pharaonis. The guest editors dedicate this special volume of Life to the memory of Prof. Hans Georg Trüper.

Background Apolipoprotein (Apo) B is the major component of low-density lipoprotein (LDL), very low-density lipoprotein (VLDL) and chylomicrons. Many genetic polymorphisms of the Apo B have been described, associated with variation of lipid levels. However, very few studies have evaluated the effect of the variable number of tandem repeats region 3' of the Apo B gene (3'APOB-VNTR) polymorphism on the lipid profiles in the special minority subgroups in China. Thus, the present study was undertaken to study the effect of the 3'APOB-VNTR polymorphism on the serum lipid levels in the Guangxi Hei Yi Zhuang and Han populations. Methods A total of 548 people of Hei Yi Zhuang were surveyed by a stratified randomized cluster sampling. The epidemiological survey was performed using internationally standardized methods. Serum lipid and apolipoprotein levels were measured. The 3'APOB-VNTR alleles were determined by polymerase chain reaction (PCR) followed by electrophoresis in polyacrylamide gels, and classified according to the number of repeats of a 15-bp hypervariable elements (HVE). The sequence of the most common allele was determined using the PCR and direct sequencing. The possible association between alleles of the 3'APOB-VNTR and lipid variables was examined. The results were compared with those in 496 people of Han who also live in that district. Results Nineteen alleles ranging from 24 to 64 repeats were detected in both Hei Yi Zhuang and Han. HVE56 and HVE58 were not be detected in Hei Yi Zhuang whereas HVE48 and HVE62 were totally absent in Han. The frequencies of HVE26, HVE30, HVE46, heterozygote, and short alleles (VNTR-LS (carrier of one long and one short alleles) than in VNTR-LL (the individual carrying two long alleles) genotypes. The levels of TC, triglycerides (TG), LDL cholesterol, and Apo B in Hei Yi Zhuang were higher in both HVE34 and HVE36 alleles than in HVE32 allele. The levels of TC, TG, HDL-C and Apo B in Hei Yi Zhuang were also higher in

The objective of this study was to investigate the association between platelet glycoprotein (GP) Ia C807T polymorphisms and ischemic stroke in young Chinese Han Population. We conducted a case-control study in 92 consecutive young (ischemic stroke inpatients and outpatients, 86 elder ischemic stroke control (> 50 years), and 160 age- and sex-matched healthy control. Genotyping of platelet GP Ia C807Tpolymorphisms was performed by polymerase chain reaction followed by sequencing nucleic acid with dideoxy chain-termination method and an ABI PRISM3100 (Perkin-Elmer Co) genetic analyzer. Student's t-test, chi-square test, and logistic regression modeling were used for data significance analyses. Hypertension and smoking were found to be the independent risk factors for ischemic stroke patients (aged ischemic stroke patients (aged > 50 years). There was no significant difference observed in the T allele frequency of GPIa C807T polymorphisms between young stroke patients and corresponding controls.

Full Text Available Abstract Background Breast cancer is a heterogeneous disease in terms of transcriptional aberrations; moreover, microarray gene expression profiles had defined 5 molecular subtypes based on certain intrinsic genes. This study aimed to evaluate the prediction consistency of breast cancer molecular subtypes from 3 distinct intrinsic gene sets (Sørlie 500, Hu 306 and PAM50 as well as clinical presentations of each molecualr subtype in Han Chinese population. Methods In all, 169 breast cancer samples (44 from Taiwan and 125 from China of Han Chinese population were gathered, and the gene expression features corresponding to 3 distinct intrinsic gene sets (Sørlie 500, Hu 306 and PAM50 were retrieved for molecular subtype prediction. Results For Sørlie 500 and Hu 306 intrinsic gene set, mean-centring of genes and distance-weighted discrimination (DWD remarkably reduced the number of unclassified cases. Regarding pairwise agreement, the highest predictive consistency was found between Hu 306 and PAM50. In all, 150 and 126 samples were assigned into identical subtypes by both Hu 306 and PAM50 genes, under mean-centring and DWD. Luminal B tended to show a higher nuclear grade and have more HER2 over-expression status than luminal A did. No basal-like breast tumours were ER positive, and most HER2-enriched breast tumours showed HER2 over-expression, whereas, only two-thirds of ER negativity/HER2 over-expression tumros were predicted as HER2-enriched molecular subtype. For 44 Taiwanese breast cancers with survival data, a better prognosis of luminal A than luminal B subtype in ER-postive breast cancers and a better prognosis of basal-like than HER2-enriched subtype in ER-negative breast cancers was observed. Conclusions We suggest that the intrinsic signature Hu 306 or PAM50 be used for breast cancers in the Han Chinese population during molecular subtyping. For the prognostic value and decision making based on intrinsic subtypes, further prospective

To investigate the distribution of Colton, Diego, Kell and Yt rare blood groups in Chinese Nanjing Han population, so as to improve the transfusion capability of patients with rare blood group and to further enrich the rare-blood-donor bank. A total of 2 015 blood samples from the blood donors were selected randomly to screen the presence of K⁺ and Kp(c+) (Kell), Yt(b+) (Yt), Co(b+) (Colton), Di(a+b+) and Di(a+b-) (Digeo) antigen allele by using PCR and multiplex PCR. Out of 2005 samples, 1 case with K⁺ gene, 8 cases with Yt(b+) gene and 100 cases with Di(a+b+) gene, 2 cases with Di(a+b-) were identified, while no Kp(c+) and Co(b+) were detected. The frequencies of K⁺, Yt(b+) and Di(a+), Di(b+) are 0.0003, 0.0013 and 0.0258, 0.9742, respectively. They are very rare blood groups in Chinese Nanjing Han population.

Full Text Available Previous studies have suggested an important role for IL-17, mainly secreted by Th17 cells, in the development of systemic inflammation in preeclampsia (PE. This study therefore investigated the association between genetic variants in IL-17A, IL-17F, and IL-17RA and susceptibility to PE in Chinese Han women. We recruited 1,031 PE patients and 1,298 controls of later pregnant women, and used TaqMan allelic discrimination real-time PCR to genotype the polymorphisms of IL17A rs2275913, IL-17F rs763780, and IL-17RA rs4819554. No significant differences in genotypic or allelic frequencies were found at all three polymorphic sites between PE patients and controls (rs2275913: genotype χ2 = 0.218, p = 0.897 and allele χ2 = 0.157, p = 0.692, OR = 1.024, 95%CI 0.911-1.152; rs763780: genotype χ2 = 1.948, p = 0.377 and allele χ2 = 1.242, p = 0.265, OR = 0.897, 95%CI 0.741-1.086; rs4819554: genotype χ2 = 0.633, p = 0.729 and allele χ2 = 0.115, p = 0.735, OR = 1.020, 95%CI 0.908-1.146. There were also no significant differences in genetic distributions between mild/severe PE or early/late-onset PE and control subgroups. Our data indicate that the genetic variants of rs2275913 in IL-17A, rs763780 in IL-17F, and rs4819554 in IL-17RA may not play a role in the pathogenesis of PE in Chinese Han women. However, these findings should be confirmed in other ethnic populations.

Full Text Available La formación de recursos humanos y la generación de conocimientos adaptados a las condiciones de explotación de las diversas produccio-nes regionales en la Argentina ocuparon la atención de los técnicos del Ministerio de Agricultura de la Nación, de las entidades agraristas y de sectores políticos y educativos diversos desde inicios del siglo XX. No escapó a ese interés la preocupación por la mujer y el “hogar agrícola”. En el presente artículo fueron analizadas, en ese contexto, las primeras décadas de la Escuela Granja “Ramón Santamarina” de Tandil, un esta-blecimiento con una rica historia institucional que albergó la primera es-cuela del hogar agrícola del país, transformada pronto en granja-escuela y especializada en industria láctea. El tránsito del “hogar agrícola” a la preparación de maestros queseros -en el marco de la orientación productivista de las escuelas en la pro-puesta educativa del Ministerio-, los sujetos sociales involucrados, la es-pecialización en quesería y sus resultados, son algunas de las cuestiones analizadas. Esto se inserta en el contexto de un proyecto educativo agra-rio pensado no solo como fuente de mano de obra, vinculado a determi-nadas industrias agrarias, sino también –y tal vez más que nada– como irradiador de ese tipo de enseñanzas hacia la comunidad.

Scale is formed when hard water is heated or cooled in heat transfer equipments such as heat exchangers, condensers, evaporators, cooling towers, boilers, and pipe walls. When scale deposits in a heat exchanger surface, it is traditionally called fouling. The objective of the present study is to investigate the formation of fouling in a heat exchanging system. A lab-scale heat exchanging system is built-up to observe and measure the formation of fouling experimentally. Water analyses are conducted to obtain the properties of Han river water. In the present study a microscopic observation is conducted to visualize the process of scale formation. Hardness of Han-river water is higher than that of tap water in Seoul

To investigate the relationship between polymorphism of Ghrelin gene and serum levels of lipoprotein in Han Chinese with or without coronary heart disease (CHD) risk factors. PCR restriction fragment length polymorphism assay was used to detect the distribution of genotypes of Ghrelin gene in 225 Han Chinese (40 to 69 years-old) with CHD risk factors, 78 subjects without CHD risk factors served as normal controls. Serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) and very low-density lipoprotein (VLDL) were measured to analyze the relationship with the polymorphism of Ghrelin gene. Ghrelin genotype frequencies of AA, AG, GG (0.975, 0.025, 0.00 in control group and 0.956, 0.040, 0.004 in the high-risk group, all P > 0.05) as well as the allele frequencies of A, G (0.987, 0.013 in control group and 0.976, 0.024 in the high-risk group, all P > 0.05) were similar between the groups. HDL-C levels of the Arg/Gln carriers were significantly lower than those of Arg/Arg carriers in control group and in the high-risk group (all P < 0.05). Arg/Gln carriers were associated lower HDL-C levels in Han Chinese.

To study the performance of pharmacogenetics-based warfarin dosing algorithms in the initial and the stable warfarin treatment phases in a cohort of Han-Chinese patients undertaking mechanic heart valve replacement. We searched PubMed, Chinese National Knowledge Infrastructure and Wanfang databases for selecting pharmacogenetics-based warfarin dosing models. Patients with mechanic heart valve replacement were consecutively recruited between March 2012 and July 2012. The predicted warfarin dose of each patient was calculated and compared with the observed initial and stable warfarin doses. The percentage of patients whose predicted dose fell within 20% of their actual therapeutic dose (percentage within 20%), and the mean absolute error (MAE) were utilized to evaluate the predictive accuracy of all the selected algorithms. A total of 8 algorithms including Du, Huang, Miao, Wei, Zhang, Lou, Gage, and International Warfarin Pharmacogenetics Consortium (IWPC) model, were tested in 181 patients. The MAE of the Gage, IWPC and 6 Han-Chinese pharmacogenetics-based warfarin dosing algorithms was less than 0.6 mg/day in accuracy and the percentage within 20% exceeded 45% in all of the selected models in both the initial and the stable treatment stages. When patients were stratified according to the warfarin dose range, all of the equations demonstrated better performance in the ideal-dose range (1.88-4.38 mg/day) than the low-dose range (pharmacogenetics-based warfarin dosing regimens performed similarly in our cohort. However, the algorithms of Wei, Huang, and Miao showed a better potential for warfarin prediction in the initial and the stable treatment phases in Han-Chinese patients undertaking mechanic heart valve replacement.

Sometimes people experience pleasant and unpleasant emotions at the same time in a single emotional event. Previous cross-cultural studies indicated that such mixed emotions are more prevalent in China and related to the attitudes toward happiness and individual’s regulatory motivation. However, China is a multi-ethnic country and not much is known about subcultural differences in mixed emotions. The aim of this study was to examine the role that implicit attitudes toward happiness and regulatory motivation played in regard of the subcultural differences in mixed emotions between Han (N = 61) and Mongolian Chinese (N = 46). Results indicated that, compared with Mongolian Chinese, Han Chinese showed stronger associations between implicit contra-hedonic attitudes toward happiness and mixed emotions during pleasant emotional events. Also, Han Chinese who reported contra-hedonic motivation during pleasant emotional events had higher levels of mixed emotions than those who had hedonic motivation. No significant differences were found in terms of mixed emotions between Mongolian Chinese who had contra-hedonic and hedonic motivation. These results suggest that the psychological mechanisms underlying differences in mixed emotions also require a more comprehensive understanding from a subcultural perspective. PMID:27833582

Full Text Available In some occasions, people experience pleasant and unpleasant emotions at the same time in a single emotional event. Previous cross-cultural studies indicated that such mixed emotions are more prevalent in China and highly related to the attitudes toward happiness and individual’s affective motivation. However, as a multi-ethnic country, not much is known about the subcultural differences in mixed emotions in China. Thus, we examined the role that implicit attitudes toward happiness and affective motivation may play in regard of the subcultural differences in mixed emotions between Han (N = 61 and Mongolian Chinese (N = 46.

Full Text Available Recent genetic association studies have implicated several candidate susceptibility variants for schizophrenia among general populations. Rs1344706, an intronic SNP within ZNF804A, was identified as one of the most compelling candidate risk SNPs for schizophrenia in Europeans through genome-wide association studies (GWASs and replications as well as large-scale meta-analyses. However, in Han Chinese, the results for rs1344706 are inconsistent, and whether rs1344706 is an authentic risk SNP for schizophrenia in Han Chinese is inconclusive. Here, we conducted a systematic meta-analysis of rs1344706 with schizophrenia in Chinese population by combining all available case-control samples (N = 12, including a total of 8,982 cases and 12,342 controls. The results of our meta-analysis were not able to confirm an association of rs1344706 A-allele with schizophrenia (p = 0.10, odds ratio = 1.06, 95% confidence interval = 0.99-1.13. Such absence of association was further confirmed by the non-superiority test (p = 0.0003, suggesting that rs1344706 is not a risk SNP for schizophrenia in Han Chinese. Detailed examinations of individual samples revealed potential sampling bias in previous replication studies in Han Chinese. The absence of rs1344706 association in Han Chinese suggest a potential genetic heterogeneity in the susceptibility of schizophrenia on this locus and also demonstrate the difficulties in replicating genome-wide association findings of schizophrenia across different ethnic populations.

Full Text Available We investigated polymorphisms of the human leukocyte antigen (HLA class I (A, B, and C loci of a Han population (n, 239 from the Yunnan province, Southwest China, using high-resolution polymerase chain reaction-Luminex (PCR-Luminex typing. We combined the HLA data from this study with the KIR genotypes from a previous study of this Han population to analyze the combination of KIR/HLA ligands. A total of 27 HLA-A, 54 HLA-B, and 31 HLA-C alleles were found in this population. The frequencies of A*11:01, A*24:02, B*40:01, B*46:01, C*01:02, C*03:04, and C*07:02 were all > 10%. The following haplotypes were common, with frequencies > 5%: 1 A-B (A*02:07-B*46:01, 2 A-C (A*02:07-C*01:02, and A*11:01-C*07:02, 4 C-B (B*13:01-C*03:04, B*40:01-C*07:02, B*46:01-C*01:02 and B*58:01-C*03:02, and 1 A-C-B (A*02:07-C*01:02-B*46:01. Analysis of KIR3D and their ligands HLA-A3/A11 and HLA-Bw4 showed that the frequencies of 3DL2+-A3/A11+ and 3DL2+-A3/A11− were 0.527 and 0.473, and the frequencies of 3DL1+-Bw4+, 3DL1+-Bw4−, 3DL1−-Bw4+, and 3DL1−-Bw4− were 0.552, 0.397, 0.038, and 0.013, respectively. The results of KIR/HLA-C combination analysis showed that all individuals had at least one inhibitory or activating KIR/HLA-C pair, and one KIR/HLA-C pair was the most frequent (157/239, followed by two pairs (46/239, three pairs (33/239, and no pairs (3/239. Comparison of KIR gene and HLA gene and their pair frequency between Yunnan Han and the isolated Han (FYDH who also lived in Yunnan province showed no significant difference (P>0.05 in KIR frequencies, but significant differences (P0.05 between the two populations for KIR/HLA pairs.

GABA system genes have been implicated in neurotrophy and neurogenesis, which play pivotal roles in an individual's variation in vulnerability to amphetamine addiction or amphetamine-induced psychosis (AIP). We hypothesized that common genetic variants in the GABA system genes may be associated with amphetamine-induced psychotic disorder. In our study, thirty-six single nucleotide polymorphisms (SNPs) within the GABA system genes were genotyped in 400 amphetamine-induced psychotic disorder patients and 400 amphetamine use disorders patients (AUP) (not including those categorized as psychosis) in the Han Chinese population. In this study, 51.88% of the Han Chinese amphetamine-type substance use disorder patients met the criteria of amphetamine-induced psychotic disorder, and 79.5% amphetamine-induced psychotic disorder patients had auditory hallucinations, while 46.5% had delusions of reference. The allele frequency of rs1129647 showed nominal association with AIP in the Han Chinese population (P=0.03). Compared with AUP group patients, T allele frequency of AIP group patients was significantly increased. The adjustment for age and gender factors in the AIP and AUP patients was executed using unconditional logistic regression under five inheritance models. The genotype frequency of rs1129647 showed nominal association with AIP in the log-additive model (P=0.04). The genotype frequency of rs2290733 showed nominal association with AIP in the recessive model (P=0.04). Compared with female AIP patients, male patients were more likely to have the CC genotype of rs17545383 (P=0.04). Moreover, we determined that more male patients carried the T allele of rs2290733 in the AIP group (P=0.004). Unfortunately, the significant differences did not survive Benjamini-Hochberg false discovery rate correction (adjusted P>0.05). No association between the SNPs of the GABA system genes and amphetamine-induced psychotic disorder risk was identified. No haplotype of the GABA system

RTEL1 (regulator of telomere elongation helicase 1; OMIM 608833) gene polymorphisms were linked to lung cancer (LC) susceptibility in a cancer genome-wide association study (GWAS) Here, we assessed whether seven previously reported RTEL1 polymorphisms influenced LC risk in Han Chinese population. All study samples (554 LC cases and 696 cancer-free controls) were collected from the Affiliated Hospital of Xizang Minzu University in China. We assessed associations between SNPs and LC risk using various several genetic models (codominant, dominant, recessive, overdominant, and additive). Whereas rs2738780 showed a protective effect against LC (Odds ratio (OR) = 0.80 ;95% confidence interval (CI): 0.638 = 0.998; p = 0.048), rs7261546(OR = 4.16; 95% CI: 1.35-12.82; p = 0.007), rs6062299(OR=5.08; 95% CI: 1.43-18.10; p = 0.005) and rs3787098(OR = 5.10; 95% CI: 1.43-18.15; p = 0.004) were all associated with increased LC susceptibility (recessive model). Haplotype analysis suggested that ''CTC'' was associated with a 0.8-fold decrease in LC risk (OR = 0.80, 95% CI, 0.63-1.00; Pearson's p = 0.05). These findings suggest a potential association between RTEL1 polymorphisms and LC risk in a Chinese Han population.

We investigated the association between single-nucleotide polymorphisms in regulation of telomere elongation helicase 1 ( RTEL1 ), which has been associated with telomere length in several brain cancers and age-related diseases, and the risk of chronic obstructive pulmonary disease (COPD) in a Chinese Han population. In a case-control study that included 279 COPD cases and 290 healthy controls, five single-nucleotide polymorphisms in RTEL1 were selected and genotyped using the Sequenom MassARRAY platform. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using unconditional logistic regression after adjusting for age and gender. In the genotype model analysis, we determined that rs4809324 polymorphism had a decreased effect on the risk of COPD (CC versus TT: OR =0.28; 95% CI =0.10-0.82; P =0.02). In the genetic model analysis, we found that the "C/C" genotype of rs4809324 was associated with a decreased risk of COPD based on the codominant model (OR =0.33; 95% CI =0.13-0.86; P =0.022) and recessive model (OR =0.32; 95% CI =0.12-0.80; P =0.009). Our data shed new light on the association between genetic polymorphisms of RTEL1 and COPD susceptibility in the Chinese Han population.

Full Text Available Tetrabromobisphenol A (TBBPA is the brominated flame retardant with the largest production volume worldwide. NTP 2-year bioassays found TBBPA dose-dependent increases in uterine tumors in female Wistar Han rats; evidence of reproductive tissues carcinogenicity was equivocal in male rats. To explain this apparent sex-dependence, the disposition and toxicokinetic profile of TBBPA were investigated using female Wistar Han rats, as no data were available for female rats. In these studies, the primary route of elimination following [14C]-TBBPA administration (25, 250 or 1000 mg/kg was in feces; recoveries in 72 h were 95.7 ± 3.5%, 94.3 ± 3.6% and 98.8 ± 2.2%, respectively (urine: 0.2–2%; tissues: <0.1. TBBPA was conjugated to mono-glucuronide and -sulfate metabolites and eliminated in the bile. Plasma toxicokinetic parameters for a 250 mg/kg dose were estimated based on free TBBPA, as determined by UV/radiometric-HPLC analyses. Oral dosing by gavage (250 mg/kg resulted in a rapid absorption of compound into the systemic circulation with an observed Cmax at 1.5 h post-dose followed by a prolonged terminal phase. TBBPA concentrations in plasma decreased rapidly after an IV dose (25 mg/kg followed by a long elimination phase. These results indicate low systemic bioavailability (F < 0.05, similar to previous reports using male rats. Elimination pathways appeared to become saturated leading to delayed excretion after a single oral administration of the highest dose (1000 mg/kg; no such saturation or delay was detected at lower doses. Chronic high exposures to TBBPA may result in competition for metabolism with endogenous substrates in extrahepatic tissues (e.g., SULT1E1 estrogen sulfation resulting in endocrine disruption.

Full Text Available Endothelial NOS (NOS3 has a potential role in the prevention of neuronal injury in hypoxic-ischemic encephalopathy (HIE. Thus, we aimed to explore the association between NOS3 gene polymorphisms and HIE susceptibility and symptoms in a Chinese Han population. Three single nucleotide polymorphisms (SNPs in the NOS3 gene, rs1800783, rs1800779, and rs2070744, were detected in 226 children with HIE and 212 healthy children in a Chinese Han population. Apgar scores and magnetic resonance image scans were used to estimate the symptoms and brain damage. The association analyses were conducted by using SNPStats and SPSS 18.0 software. The genotype and allele distributions of rs1800779 and rs1799983 displayed no significant differences between the patients and the controls, while the rs2070744 allele distribution was significantly different (corrected P=0.009. For clinical characteristics, the rs2070744 genotype distribution was significantly different in patients with different Apgar scores (≤5, TT/TC/CC = 6/7/5; 6~7, TT/TC/CC = 17/0/0; 8~9, TT/TC/CC = 6/2/0; 10, TT/TC/CC = 7/1/0; corrected P=0.006 in the 1001 to 1449 g birth weight subgroup. The haplotype test did not show any associations with the risk and clinical characteristics of HIE. The results suggest that NOS3 gene SNP rs2070744 was significantly associated with HIE susceptibility and symptom expression in Chinese Han population.

To compare the incidence of postoperative pain of chronic periapical periodontitis patients with root canal therapy between Han and Uygur, and the effect of ibuprofen in reducing endodontic flare-up after single-visit root canal therapy between Uyghur and Han patients with chronic apical periodontitis, in order to provide a basis for clinical administration. Two hundred and fifty Uyghur and 250 Han patients with chronic apical periodontitis in their incisor, canine and premolar were collected, and randomly divided into 2 groups: experimental group and control group. After single-visit root canal therapy, Uyghur patients in the experimental group (UEG) and Han patients in the experimental group (HEG) took ibuprofen capsules according to the drug instructions; while Uyghur patients in the control group (UCG) and Han patients in the control group(HCG) took placebo capsules. Both doctors and patient kept blind from the drug capsules and group of the patients. The incidence, degree of endodontic Flare-up at 6, 12, 24, 48, 72 hours and 1 week after root canal therapy were recorded and analyzed by χ 2 test using SPSS11.0 software package. During the experiment, the incidence of E flare-up in Uygur patients was higher than in Han patients; the incidence of E flare-up in different groups in orders from high to low was: UCG>HCG>UEG>HEG. Chi-square test showed that there were significant differences between the two groups. In view of time distribution, most of flare-up happened between 24~48 hours after root canal therapy with the highest degree in all 4 groups. Regardless of the incidence or degree of flare-up, HEG and HCG were significantly greater than UEG and UCG. Ibuprofen can reduce and prevent flare-up for both Uyghur and Han patients, but it has better effect on Han patients.

We tested the hypothesis that genetic variation in ATM and BMI-1 genes can alter the risk of breast cancer through genotyping 6 variants among 524 breast cancer cases and 518 cancer-free controls of Han nationality. This was an observational, hospital-based, case-control association study. Analyses of single variant, linkage, haplotype, interaction and nomogram were performed. Risk was expressed as odds ratio (OR) and 95% confidence interval (CI). All studied variants were in the Hardy-Weinberg equilibrium and were not linked. The mutant allele frequencies of rs1890637, rs3092856 and rs1801516 in ATM gene were significantly higher in cases than in controls (P = .005, ATM gene were significantly associated with 1.98-fold and 6.04-fold increased risk of breast cancer (95% CI: 1.36-2.90 and 1.65-22.08, respectively). Nomogram analysis estimated that the cumulative proportion of 3 significant variants in ATM gene was about 12.5%. Our findings collectively indicated that ATM gene was a candidate gene in susceptibility to breast cancer in Han Chinese. © 2018 The Authors.
