Da a conocer la rehabilitación oral de una paciente con edentulismo parcial que presentaba implantes los cuales se encontraron colocados tridimensionalmente en una posición desfavorable, tanto en altura como inclinación, así mismo al examen clínico se observó desgaste de las piezas dentarias presentes, las cuales según la clasificación de Turner y Missirilian se encuentra en una categoría 1 lo que refiere desgaste con pérdida de dimensión vertical y por otro lado Vailati et al, en una clasificación ACE tipo 4 lo cual hace referencia a un desgaste con exposición de dentina a nivel palatino mayor a 2 milímetros, sin embargo conserva la parte vestibular. La rehabilitación oral de los dientes con desgaste fue orientadas a devolver la estética y función usando técnicas menos invasivas y conservadores, donde se restablece la dimensión vertical. Por las condiciones clínicas con respecto a la mala posición y la marcada pérdida ósea vertical, se optó por realizar una prótesis dentogingival, buscando así mejorar la estética por lo cual se utilizó una estructura de zirconia para buscar el mimetismo con las prótesis fijas adhesivas. En conclusión la realización de un diagnóstico, un planeamiento correcto, y respetando protocolos se puede rehabilitar satisfactoriamente casos con implantes en posición inadecuadas y teniendo una filosofía conservadora se puede realizar una rehabilitación fija mínimamente invasiva.Trabajo académic

Knowledge, attitude and practice of blood donation among undergraduate students in a public university, Malaysia

Blood donation save millions of lives. An increasing demand for blood in almost all medical centers throughout Malaysia indicated the requirement for more blood donors. The current strategy of blood donor programs in all blood centers in order to overcome the shortage of donations of safe blood in Malaysia is to make a maximum effort to recruit safe blood donors from special, low-risk groups, such as university students. The study was to determine the knowledge, attitude, and practices among undergraduate health sciences students regarding blood donations in a public university. A cross-sectional study was conducted among undergraduate health sciences students. The data were collected from February until April 2016 and SPSS, version 20.0 was used to analyze the data. The result revealed, a total of 210 undergraduate health sciences student participated in this study. Approximately, 46.2% had adequate knowledge, 57.1% had a positive attitude towards blood donation and less than 50% of the respondents had ever donated blood. Although there is positive attitude of blood donation among student but there is low level of knowledge of blood donation. Therefore, there is need to intensify public awareness and knowledge on blood donation. The campaign on blood donation should be continued with various methods to create more opportunities for the students, which can greatly enhance their knowledge, promote positive attitude and good blood donation practice

Physical activity and health promoting lifestyle among diploma nursing students in Malaysia

The aims of this study are to assess the physical activity level and health-promoting lifestyle among diploma nursing students in Malaysia. Besides, this study also aims to compare whether there were significant differences in term of the physical activity level and health-promoting lifestyle between urban and rural diploma nursing students. This study involved 123 diploma nursing students who currently pursuing the diploma degrees in the two local government institutions. The YAMAX Digi-Walker pedometer was used to measure physical activity based on their weekly (7 days) step counts. And the Health-promoting Lifestyle Profile (HPLP) II questionnaire was used to measure the nursing student’s health-promoting lifestyle. The HPLP II consisted of six sub-scales which included health responsibility, physical activity, nutrition, spiritual growth, interpersonal relations, and stress management. The mean weekly step counts reported was 8839.96±2613.58 steps. The diploma nursing students in the urban institution were reported to have higher mean step counts as compare to the diploma nursing students in the rural institution. Mean score obtained for HPLP II among the diploma nursing students was 2.56±0.34. Both diploma nursing students were found to have the highest score for spiritual growth, follow by interpersonal relations and stress management. Meanwhile, health responsibility was reported to be the lowest score for both institutions. Since unhealthy behaviors are associated positively with the nurses’ health promotion roles in the future, so encouraging them to live healthily starting when they were pursuing their diploma was necessary in order to achieve this noble mission

Educación ambiental y conocimientos sobre el cambio climático de los estudiantes de la institución educativa N° 56111 Pongoña Canas 2021

El cambio climático afecta a la población genera la degradación de los ecosistemas y pérdida de biodiversidad, el estrés e inseguridad hídrica, la menor producción de alimentos e inseguridad alimentaria y la afectación de la salud humana. Uno de los casos más preocupantes es el de los Andes peruanos donde se produce una acelerada desglaciación, que reduce las fuentes de agua afectando importantes actividades económicas como la agricultura y la ganadería; a lo antes señalado se suman los efectos sobre la salud. Frente a este panorama, el Perú ha planteado la “estrategia nacional ante el cambio climático”, y el plan nacional de educación ambiental (PLANEA) que plantean desarrollar la educación y la cultura ambiental, orientadas a la formación de una ciudadanía ambientalmente responsable y una sociedad peruana sostenible, competitiva, inclusiva y con identidad. En este contexto, la investigación tuvo como objetivo determinar los conocimientos sobre el cambio climático que han generado los procesos de educación ambiental y se desarrolló siguiendo un diseño no experimental - transeccional. Los resultados proporcionados por los instrumentos de investigación, revelan que en la Institución Educativa N° 56111 Pongoña, si bien existen avances en la estructuración de instrumentos de gestión institucional y pedagógica con enfoque ambiental, existen limitaciones en la implementación de los lineamientos propuestos por el Ministerio de Educación para prepararse y mitigar los efectos del cambio climático. Se encontraron además limitaciones en los estudiantes respecto de la comprensión de este fenómeno, sus causas y consecuencias

The extreme UV imager telescope on-board the Solar Orbiter mission: overview of phase C and D

The Solar Orbiter mission is composed of ten scientific instruments dedicated to the observation of the Sun’s atmosphere and its heliosphere, taking advantage of an out-of ecliptic orbit and at perihelion reaching a proximity close to 0.28 A.U. On board Solar Orbiter, the Extreme Ultraviolet Imager (EUI) will provide full-Sun image sequences of the solar corona in the extreme ultraviolet (17.1 nm and 30.4 nm), and high-resolution image sequences of the solar disk in the extreme ultraviolet (17.1 nm) and in the vacuum ultraviolet (121.6 nm). The EUI concept uses heritage from previous similar extreme ultraviolet instrument. Additional constraints from the specific orbit (thermal and radiation environment, limited telemetry download) however required dedicated technologies to achieve the scientific objectives of the mission. The development phase C of the instrument and its sub-systems has been successfully completed, including thermo-mechanical and electrical design validations with the Structural Thermal Model (STM) and the Engineering Model (EM). The instrument STM and EM units have been integrated on the respective spacecraft models and will undergo the system level tests. In parallel, the Phase D has been started with the sub-system qualifications and the flight parts manufacturing. The next steps of the EUI development will be the instrument Qualification Model (QM) integration and qualification tests. The Flight Model (FM) instrument activities will then follow with the acceptance tests and calibration campaigns

The Extreme Ultraviolet Imager (EUI) onboard the SOLAR ORBITER mission

peer reviewedSolar Orbiter will for the first time study the Sun with a full suite of in-situ and remote sensing instruments from inside 0.25 AU and will provide imaging and spectral observations of the Sun’s polar regions, from out of the ecliptic. This proximity to the Sun will also have the significant advantage that the spacecraft will fly in near synchronization with the Sun’s rotation, allowing observations of the solar surface and heliosphere to be studied from a near co-rotating vantage point for almost a complete solar rotation. The mission’s ambitious characteristics draw severe constraints on the design of these instruments. The scientific objectives of Solar Orbiter rely ubiquitously on the Extreme EUV Imager suite (EUI). The EUI instrument suite on board of Solar Orbiter is composed of two high resolution imagers (HRI), one at Lyman α and one dual band at the two 174 and 335 EUV passbands in the extreme UV, and one dual band full-sun imager (FSI) working alternatively at the two 174 and 304 EUV passbands. In all the units, the image is produced by a mirror-telescope, working in nearly normal incidence. The EUV reflectivity of the optical surfaces is obtained with specific EUV multilayered coatings, providing the spectral selection of the EUV units (1HRI and 1 FSI). The spectral selection is complemented with very thin filters rejecting the visible and IR radiation. Due to its orbit, EUI / Solar Orbiter will see 20 solar constants and an entrance baffle to limit the solar heat input into EUI is needed. The paper presents the scientific objectives of EUI and also covers the EUI instrument development plan which will require some trade-off between existing and promising technologies

Space radiation parameters for EUI and the Sun Sensor of Solar Orbiter, ESIO and JUDE instruments

This paper presents predictions of space radiation parameters for four space instruments performed by the Centre Spatial de Liège (ULg – Belgium); EUI, the Extreme Ultra-violet Instrument, on-board the Solar Orbiter platform; ESIO, Extreme-UV solar Imager for Operations, and JUDE, the Jupiter system Ultraviolet Dynamics Experiment, which was proposed for the JUICE platform. For Solar Orbiter platform, the radiation environment is defined by ESA environmental specification and the determination of the parameters is done through ray-trace analyses inside the EUI instrument. For ESIO instrument, the radiation environment of the geostationary orbit is defined through simulations of the trapped particles flux, the energetic solar protons flux and the galactic cosmic rays flux, taking the ECSS standard for space environment as a guideline. Then ray-trace analyses inside the instrument are performed to predict the particles fluxes at the level of the most radiation-sensitive elements of the instrument. For JUICE, the spacecraft trajectory is built from ephemeris files provided by ESA and the radiation environment is modeled through simulations by JOSE (Jovian Specification Environment model) then ray-trace analyses inside the instrument are performed to predict the particles fluxes at the level of the most radiation-sensitive elements of the instrument

Nursing workload in relation to nosocomial infection in public hospital Intensive Care Unit, Malaysia

Nosocomial infections (NIs) is an infection acquired in the hospital and becomes evident 48 hours after admission to the hospital.It continues to be a major problem affecting patient safety and quality of care in Intensive Care Unit (ICU).One of the most pertinent factors leading to NIs is nursing workload. The aim of the study is to determine nursing workload on NIs rate in the ICU, Hospital Serdang. A retrospective cross sectional study was used. Data were collected from NIs surveillance,staff nurses’ duty roster and patient census by using a performa.The result in this study shows,19 %( n=88)cases of NIs were detected in 12 %( n=57) of patient. There was significant moderate positive relationship between the number of infection and the total number of nurses working overtime (r= 0.66,n=88, p = 0.001) and the number of infection and the total number of new staffs (r= 0.51, n=88, p = 0.001). There was significant weak positive relationship between the number of infection and the total number of nurses taking medical leave or emergency leave (r= 0.33, n=88, p = 0.001). This study provide a baseline to improve nursing staffing in ICU. Future planning of ICU staffing should be comprehensive so that patients are not disadvantaged

Automatized alignment of the focal plane assemblies on the PLATO cameras

peer reviewedPLATO (PLAnetary Transits and Oscillation of stars) is a medium-class space mission part of the ESA Cosmic vision program. Its goal is to find and study extrasolar planetary systems, emphasizing on planets located in habitable zone around solar-like stars. PLATO is equipped with 26 cameras, operating between 500 and 1000nm. The alignment of the focal plane assembly (FPA) with the optical assembly is a time consuming process, to be performed for each of the 26 cameras. An automatized method has been developed to fasten this process. The principle of the alignment is to illuminate the camera with a collimated beam and to vary the position of the FPA to search for the position which minimizes the RMS spot diameter. To reduce the total number of measurements which is performed, the alignment method is done by iteratively searching for the best focus, decreasing at each step the error on the estimated best focus by a factor 2. Because the spot size at focus is similar to the pixel, it would not be possible with this process alone to reach an alignment accuracy of less than several tens of microns. Dithering, achieved by in-plane translation of the focal plane and image recombination, is thus used to increase the sampling of the spot and decrease the error on the merit function
