Background: Infective endocarditis is a serious complication in patients with prostheses in the right ventricle outflow tract. The aim of our study is to assess clinical features in these patients. Methods: We have analyzed all cases of prosthetic pulmonary valve infective endocarditis (PPVIE) and compared them to the rest of the patients with IE. Since the year 2000, 375 cases of IE have been diagnosed in our center and nine patients had a PPVIE.: 3 patients with Melody percutaneous prostheses, 5 with a homograft (3 after a Rastelli procedure, 2 a Ross procedure), and 1 patient with a heterograft (Contegra conduit). Results: Mean age of PPVIE patients was 31±15 years old and 89% were male. A presumed portal of entry could only be identified in 4 of the 9 patients with PPVIE. The most common was a dental origin (3 patients). A causative microorganism was detected in all but one PPVIE patient: 3 S.viridans, 2 S.aureus, 2 coagulase-negative staphylococci, and 1 enterococcus. Most patients suffered complications during the in-hospital phase: 7 out of 9 PPVIE patients (78 vs.75% of the rest of IE patients), the most common congestive heart failure (5 patients), and persistent sepsis (4 patients). Six patients were operated on during hospitalization (67 vs. 55%) with a mean time from admission to surgery of 15 days. In-hospital mortality was similar (22 vs. 26%). Conclusions: Prevalence of PPVIE is low, with a clinical outcome, surgery rate, and survival similar to the rest of patients with IE.

The purpose of this study is to describe the inability of Catholic education institutions on funding school operations especially regarding teacher salaries in Medan. The main task of the teacher is to do educational assignments. Even though it is not optimal, the cooperation and commitment of all parties involved, especially the institution and the school parties are needed in terms of designing and realizing various collaborative efforts with the church and parents, so that new students will grow in Catholic schools. This study is conducted by using descriptive qualitative approach. The result shows that there is no good achievement without hard work and sacrifice and also a good work approach strategy. Therefore there must be good meetings that create a positive attitude and a sense of belonging to the school, where if the school is successfully developed, all parties will feel the benefits.

La presente investigación tuvo como objetivo general determinar y describir la influencia de los incentivos fiscales en el cumplimiento tributario de las micro y pequeñas empresas (MYPES) del sector comercio minorista – rubro lubricantes automotriz del distrito de Chimbote, en el año 2014. La investigación fue de tipo cuantitativo, no experimental, transversal y correlacional – causal. La información se recabó de 51 MYPES, muestra seleccionada de entre una población de 109 empresas pertenecientes al sector y rubro investigado, aplicándoseles un cuestionario de 12 preguntas vía encuesta. Los principales resultados fueron: con respecto a las principales características de las MYPES, el 86,27% sobrepasan los cinco años de operaciones en dicho rubro comercial, el 84,31% tributan en el Régimen General del impuesto a la renta y el 94,12% son negocios constituidos como personas naturales; con respecto a los incentivos fiscales el 31,37% de las MYPES considera que en su actual régimen de renta le aplican beneficios tributarios, un 37,50% considera que el beneficio tributario implícito a su régimen de renta ha tenido el impacto esperado y solo el 5,88% conoce la ley N° 30056 y los beneficios tributarios otorgados en ella; con respecto al incumplimiento tributario un 62,75% de la muestra afirma haber cumplido con todas sus obligaciones tributarias del ejercicio 2014, de impuestos fue señalado por el 54,90% ve el pago de impuestos como la mayor dificultad de cumplimiento en la obligación tributaria y un 31,25% de las MYPES que reconocen beneficios tributarios implícitos en su régimen de renta considera que los beneficios tributarios influyen en el cumplimiento de las obligaciones tributarias. Finalmente, se ha comprobado estadísticamente, con un nivel de significancia igual al 5%, que no existe relación significativa entre los incentivos fiscales otorgados a las MYPES y el cumplimiento tributario.

Aquest treball d'investigació s'ha dirigit a aconseguir una primera aproximació a les condicions de treball dels i les professionals del tercer sector que intervenen específicament amb persones d'origen estranger a Catalunya, arran de la manca de dades específiques al seu voltant i les possibles implicacions d'aquestes condicions de treball (afectacions a la salut, grau de benestar percebut, etc.). Concretament, la investigació s'ha dirigit a intentar conèixer les condicions laborals, possibles situacions de precarietat laboral i els riscos psicosocials més habituals d'aquest col·lectiu de professionals, així com de visibilitzar les seves percepcions i demandes. De les principals conclusions obtingudes, podem destacar aspectes relacionats amb la precarietat, com són una elevada taxa de temporalitat contractual i salaris per sota de la mitjana estatal i catalana. També existeixen forts factors de protecció, que ajuden a assolir un grau de benestar mig al lloc de treball, com són el suport de la resta de companys/es i l'existència d'un bon ambient de treball. Així mateix, és important mencionar l'impacte dels factors gènere i edat dintre de les condicions laborals que presenten. Entre els riscos psicosocials més habituals, destaquen l'alta exigència emocional, l'alt ritme de treball i l'excessiva quantitat d'aquest. Les afectacions a la salut no són molt freqüents, però sí que tenen un notable impacte a la vida de les persones afectades. Entre les mesures proposades, les més reclamades són canvis organitzatius i de planificació per part de les entitats, millores salarials i de conveni, i un augment dels recursos destinats al sector. This research work has been aimed at achieving a first approximation to the working conditions of the professionals of the third sector who intervene specifically with people of foreign origin in Catalonia, due to the lack of specific data around them and possible implications of these working conditions (health effects, degree of perceived well-being, etc.). Specifically, the research has been directed to try to know the working conditions, possible situations of precarious work and the most common psychosocial risks of this group of professionals, as well as to make visible their perceptions and demands. From the main conclusions obtained, we can highlight aspects related to precariousness, such as a high rate of contractual temporality and salaries below the state and Catalan average. There are also strong protective factors, which help to achieve a medium level of well-being for the job, such as the support of other colleagues and the existence of a good work environment. Likewise, it is important to mention the impact of gender and age factors within the working conditions they present. Among the most common psychosocial risks, the high emotional demand, the high work rate and the excessive amount of this stand out. Health effects are not very frequent, but they do have a significant impact on the lives of the people affected. Among the proposed measures, the most demanded are organizational and planning changes by the entities, salary and agreement improvements, and an increase in resources allocated to the sector.

Since the end of the Apollo missions to the lunar surface in December 1972, humanity has exclusively conducted scientific studies on distant planetary surfaces using teleprogrammed robots. Operations and science return for all of these missions are constrained by two issues related to the great distances between terrestrial scientists and their exploration targets: high communication latencies and limited data bandwidth. Despite the proven successes of in-situ science being conducted using teleprogrammed robotic assets such as Spirit, Opportunity, and Curiosity rovers on the surface of Mars, future planetary field research may substantially overcome latency and bandwidth constraints by employing a variety of alternative strategies that could involve: 1) placing scientists/astronauts directly on planetary surfaces, as was done in the Apollo era; 2) developing fully autonomous robotic systems capable of conducting in-situ field science research; or 3) teleoperation of robotic assets by humans sufficiently proximal to the exploration targets to drastically reduce latencies and significantly increase bandwidth, thereby achieving effective human telepresence. This third strategy has been the focus of experts in telerobotics, telepresence, planetary science, and human spaceflight during two workshops held from October 3–7, 2016, and July 7–13, 2017, at the Keck Institute for Space Studies (KISS). Based on findings from these workshops, this document describes the conceptual and practical foundations of low-latency telepresence (LLT), opportunities for using derivative approaches for scientific exploration of planetary surfaces, and circumstances under which employing telepresence would be especially productive for planetary science. An important finding of these workshops is the conclusion that there has been limited study of the advantages of planetary science via LLT. A major recommendation from these workshops is that space agencies such as NASA should substantially increase science return with greater investments in this promising strategy for human conduct at distant exploration sites., K 20200609-101330976
