Published: May 2019

Latar Belakang : Remaja adalah masa peralihan masa kanak-kanak ke masa dewasa mulai 14-20 tahun. Masa remaja merupakan masa kritis seseorang yang dihadapkan pada berbagai tantangan dan masalah karena sifatnya yang sensitif dan rawan menyangkut moral, etik, agama, salah satu resiko yang bisa terjadi adalah perilaku seksual pra nikah. Tujuan : Tujuan penelitian ini untuk mengeksplorasi pengetahuan, penyebab dan akibat perilaku seksual pra nikah pada siswi SMA Setia Budhi Semarang. Metode Penelitian : Penelitian ini menggunakan metode kualitatif dengan pendekatan etnografi. Pengambilan sampel menggunakan purposive sampling sampai data mengalami saturasi. Teknik pengumpulan data dengan wawancara mendalam. Hasil : Persepsi remaja tentang perilaku seksual pra nikah yaitu ciuman dan berhubungan intim, penyebab terjadinya yaitu karena adanya kebebasan dan izin dari orang tua untuk berpacaran tanpa adanya pengarahan dan pemantauan dari orang tua dan keluarga, sehingga dampaknya dapat menyebabkan kehamilan yang tidak diinginkan dan putus sekolah, kurangnya pengetahuan dan informasi yang didapatkan remaja tentang perilaku seksual pra nikah sehingga pacaran dan melakukan perilaku seperti ciuman, pelukan dan meraba daerah payudara sudah dianggap biasa. Saran: Pihak sekolah diharapkan meningkatkan kerja sama dengan Dinas Kesehatan dan Puskesmas agar melakukan program kesehatan reproduksi remaja secara rutin di tiap SMA berupa penyuluhan.

The adolescents is the critic time for someone who faces threat and problem, because they have sensitive and troubled character in morality, ethic and religion. One of the risk is the premarital sexual behavior. Purpose : To explore the knowledge, the causes and consequences of premarital sexual behavior of female students at Setia Budhi High School Semarang. Method of The Research : This research used qualitative method with ethnographic approach. The sampling of this research used purposive sampling until data experiencing saturation. The data collection technique was interview. Result : The perceptions of premarital sexual behavior are kissing and having sex. The causes because the parents gave permission freely to make a date without any briefing and monitoring. It can make unwanted pregnancies and the female students can be dropout from school. Because of the less of the students knowledge and information about premarital sexual behavior, they usually make a date by doing kissing, cuddling and touching breast freely considered normal. Suggestion : This research is hoped that the school management can improve the cooperation with public health office and public health service in creating the continuing program about reproduction health like health education.

Published: May 2019

Actualmente, los equipos directivos asumen el reto de conducir una escuela sólo desde un conocimiento pedagógico, (Shulman, 1989) sin contar con la especialización que implica una gestión como dirección escolar. Esta realidad nos lleva a cuestionar la gestión institucional y motiva a buscar estrategias que proporcione a los equipos directivos experiencias de aprendizaje para mejorar su gestión, y en este caso, la gestión de la convivencia escolar.
El presente trabajo presenta el análisis de los equipos directivos respecto a la gestión participativa como una propuesta para el abordaje de la convivencia escolar en 21 centros educacionales municipales de la provincia de Ñuble.
Así, se pudo verificar que los espacios de diálogo y reflexión son cruciales para el logro metas. La gestión institucional requiere de un proceso de coordinación que organice las estructuras y espacios de diálogo para alcanzar los ejes estratégicos de trabajo planteados en la normativa vigente de convivencia escolar. Por tanto, un desafío para los directivos es lograr mantener la importancia de la reflexión y diálogo en la gestión institucional. De acuerdo a los resultados de esta investigación, generalmente los obstáculos de la convivencia surgen en contextos educativos donde no hay coordinaciones internas ni espacios en la participación de toma de decisiones, lo que genera percepciones de injusticia entre quienes conforman las comunidades escolares.

La autorregulación del aprendizaje apunta a generar un proceso autónomo en los alumnos; en base a este enfoque, consideramos que la tarea educativa debe dirigirse a la formación de competencias que permiten el aprender a aprender, logrando así un aprendizaje constante y continuo durante toda la vida en las diferentes situaciones y ámbitos en los que deba desenvolverse y, fundamentalmente, habilitar espacios en los que el estudiante genere nuevas formas de pensamiento y comportamiento. Por todo esto, comenzamos a investigar y buscar alternativas y estrategias variadas para poder modificar la forma en la que cada docente acerca los saberes a los alumnos, incidiendo en la metodología y estrategias de enseñanza, buscando que los alumnos se involucren en su propio aprendizaje, se responsabilicen por el mismo y sean conscientes de las modificaciones que se produce en ellos. Para abordar esta situación, desde la neurodidáctica creamos proyectos en distintos espacios curriculares, donde los profesores propiciaron que el aprendizaje esté centrado en el estudiante, considerándolo como eje del proceso, reconociendo, aceptando y respetando que es él quien realiza una construcción activa del conocimiento con la guía del profesor y sus compañeros. A lo largo de este escrito presentamos la articulación desde la teoría a la práctica a través de los diferentes espacios curriculares.

Background Infectious peritonitis is a clinically important condition contributing to the significant mortality and morbidity rates observed in peritoneal dialysis (PD) patients. Although some of the socioeconomic risk factors for PD-associated peritonitis have been identified, it is still unclear why certain patients are more susceptible than others to infection. Methods We examined the molecular components of human peritoneal dialysate (HPD) in an attempt to identify factors that might increase patient susceptibility to infection. Characterization studies were performed on initial and follow-up dialysate samples collected from 9 renal failure patients on PD. Results Our in vitro data showed that peritonitis-causing bacteria grew differently in the patient dialysates. Proteomic analysis identified an association between transferrin presence and infection risk, as peritoneal transferrin was discovered to be iron-saturated, which was in marked contrast to transferrin in blood. Further, use of radioactive iron-labeled transferrin showed peritoneal transferrin could act as a direct iron source for the growth of peritonitis-causing bacteria. We also found catecholamine stress hormones noradrenaline and adrenaline were present in the dialysates and were apparently involved in enhancing the growth of the bacteria via transferrin iron provision. This suggests the iron biology status of the PD patient may be a risk factor for development of infectious peritonitis Conclusions Collectively, our study suggests transferrin and catecholamines within peritoneal dialysate may be indicators of the potential for bacterial growth in HPD and, as infection risk factors, represent possible future targets for therapeutic manipulation.

Background Residual renal function (RRF) affects sodium and fluid balance. The aim of this analysis was to examine the impact of RRF on the effect of a sodium-reduced peritoneal dialysis fluid (PDF) on blood pressure (BP). Methods This is a post-hoc analysis of a prospective, randomized, controlled double-blind clinical trial with 82 patients on continuous ambulatory PD (CAPD) treated with a low-sodium (125 mmol/L Na) or a standard-sodium (134 mmol/L Na) PDF. Subgroups according to glomerular filtration rate (GFR) at baseline (≤ / > 6 mL/min/1.73 m2) were analyzed for BP and antihypertensive medication. Results In the low-GFR group on low-sodium PDF ( N = 26), systolic BP was reduced from 152 ± 24 mmHg at baseline to 137 ± 21 mmHg at week 12, diastolic BP from 90 ± 16 mmHg to 83 ± 11 mmHg. In the low-GFR group on standard-sodium PDF and in the high-GFR group on both PDF types, only minor changes were observed. For the low-GFR subgroup, the confounder-adjusted mean study group difference in systolic BP at week 12 between low-sodium and standard-sodium PDF was -16.9 (95% confidence interval [CI] -27.2 to -6.6) mmHg, for diastolic BP, it was -7.0 (95% CI -12.6 to -1.4) mmHg. In both GFR subgroups, more patients had a reduced daily dose of antihypertensive medication and fewer patients an increased daily dose in the low-sodium compared with the standard-sodium group at week 12. Conclusions The reduction of BP with a sodium-reduced PDF seems to be more effective in patients with no or low RRF than in patients with residual capacity of renal sodium and fluid control.

Background The most common complication of peritoneal dialysis (PD) is infection. Despite this, there are no clear guidelines for the management of repeat exit-site infection (ESI), and best practice is not known. We describe our unit's experience of repeat ESI and clinical outcomes in this cohort. Methods Retrospective case note review of all PD patients with positive ESI swabs at our center between 1 January 2012 and 1 January 2018. Patients were included in the study if they had 2 or more ESI with the same organism within a 12-month period and an initial positive response to antibiotic therapy. Results Overall, 31 of 248 patients had repeat ESI. The 2 most common causative organisms were Staphylococcus aureus ( n = 16, 52%) and Pseudomonas aeruginosa ( n = 10, 32%). Twenty (65%) patients developed subsequent peritonitis. The infection resolved with further antibiotics alone in 10 (32%) patients and in 6 patients after PD catheter exchange. The PD catheter was removed in 16 (52%) patients (including 5 after an initial catheter exchange) requiring transfer to hemodialysis (HD). Six (19%) patients died within 12 months of repeat ESI. Both repeat Pseudomonas aeruginosa and Staphylococcus aureus infections were associated with high rates of dialysis modality change (70% and 50%, respectively). Conclusion We have developed the first definition for repeat ESI. Repeat ESI is clinically important and results in significant morbidity and mortality. Following repeat ESI, peritonitis rates are high and a significant number of patients switch dialysis modality. Studies are needed to determine whether interventions such as early catheter exchange would improve outcomes.

Background Little evidence exists regarding optimal peritoneal dialysis (PD) access insertion pathways, benchmarking for patency targets, and definitions of access dysfunction. Methods This quality improvement (QI) project evaluated patients with PD catheters inserted at a single center in Toronto, Canada, following: establishment of PD catheter insertion protocols, a PD access coordinator, PD access operator training, and outcomes reporting. We define primary vs secondary PD catheter dysfunction by presentation before/after initial home PD treatment. We report catheter dysfunction rates, interventions restoring PD catheter patency (interventional radiology [IR] vs advanced laparoscopic [AL]) (embedded vs non-embedded) between 2012 and 2017. Results A total of 297 first PD catheters were inserted between January 2012 and December 2017. Interventional radiology PD catheters ( n = 94) were placed in older patients with greater comorbidities and less prior abdominal surgery than AL-placed catheters. Indications for IR insertion included need for urgent dialysis given resource availability (36.2% [ n = 34]) and prohibitive surgical risk (26.6% [ n = 25]). Interventional radiology-inserted catheters had overall (primary and secondary) dysfunction rates of 17%. Non-embedded AL catheters had 16.1% overall dysfunction. Embedded AL-inserted PD catheters had a 24.6% overall dysfunction rate. Among all dysfunctional catheters, IR manipulation was successful in 31% ( n = 11), and surgical revision was necessary in all unsuccessful cases with either lysis of adhesions or omentopexy to establish patency. Conclusion Our PD catheter QI initiative involved tracking, outcome reporting, defining PD catheter dysfunction and PD access insertion pathway development, yielding important insights into opportunities for program improvement. Multicenter research initiatives are needed to further improve PD access dysfunction definitions and to establish the best benchmarks for these metrics.

Abstract
We investigated the time-variability and spectral properties of the eclipsing X-ray source Circinus Galaxy X-1 (GG X-1), using Chandra, XMM-Newton and ROSAT. We phase-connected the light curves observed over 20 yr, and we obtained a best-fitting period P = (25,970.0 ± 0.1) s ≈ 7.2 hr, and a period derivative

yr−1. The X-ray light curve shows asymmetric eclipses, with sharp ingresses and slow, irregular egresses. The eclipse profile and duration vary substantially from cycle to cycle. We show that the X-ray spectra are consistent with a power-law-like component, which is absorbed by neutral and ionized Compton-thin material, and by a Compton-thick, partial-covering medium, which is responsible for the irregular dips. The high X-ray/optical flux ratio rules out the possibility that CG X-1 is a foreground Cataclysmic Variable. In agreement with previous studies, we conclude that it is the first example of a compact ultraluminous X-ray source fed by a Wolf–Rayet star or stripped Helium star. Its unocculted luminosity varies between ≈4 × 1039 erg s−1 and ≈3 × 1040 erg s−1. Both the donor star and the super-Eddington compact object drive powerful outflows. We suggest that the occulting clouds are produced in the wind–wind collision region and in the bow shock in front of the compact object. Among the rare sample of Wolf–Rayet X-ray binaries, CG X-1 is an exceptional target for studies of supercritical accretion and close binary evolution; it is also a likely progenitor of gravitational wave events.
Tidal Disruptions of Stars by Binary Black Holes: Modifying the Spin Magnitudes and Directions of LIGO Sources in Dense Stellar Environments

Published: May 2019

Abstract
Binary black holes (BBHs) appear to be widespread and are able to merge through the emission of gravitational waves, as recently illustrated by Laser Interferometer Gravitational-Wave Observatory (LIGO). The spin of the BBHs is one of the parameters that LIGO can infer from the gravitational-wave signal and can be used to constrain their production site. If BBHs are assembled in stellar clusters, they are likely to interact with stars, which could occasionally lead to a tidal disruption event (TDE). When a BBH tidally disrupts a star, it can accrete a significant fraction of the debris, effectively altering the spins of the BHs. Therefore, although dynamically formed BBHs are expected to have random spin orientations, tidal stellar interactions can alter their birth spins both in direction and magnitude. Here we investigate how TDEs by BBHs can affect the properties of the BH members as well as exploring the characteristics of the resulting electromagnetic signatures. We conduct hydrodynamic simulations with a Lagrangian Smoothed Particle Hydrodynamics code of a wide range of representative tidal interactions. We find that both spin magnitude and orientation can be altered and temporarily aligned or anti-aligned through accretion of stellar debris, with a significant dependence on the mass ratio of the disrupted star and the BBH members. These tidal interactions feed material to the BBH at very high accretion rates, with the potential to launch a relativistic jet. The corresponding beamed emission is a beacon to an otherwise quiescent BBH.
Effects of Synchrotron Cooling and Pair Production on Collisionless Relativistic Reconnection

Abstract
High-energy radiation from nonthermal particles accelerated in relativistic magnetic reconnection is thought to be important in many astrophysical systems, ranging from blazar jets and black hole accretion disk coronae to pulsars and magnetar flares. The presence of a substantial density of high-energy photons (>MeV) in these systems can make two-photon pair production (γγ → e

+) an additional source of plasma particles and can affect the radiative properties of these objects. We present the results of novel particle-in-cell simulations that track both the radiated synchrotron photons and the created pairs, with which we study the evolution of a two-dimensional reconnecting current sheet in pair plasma. Synchrotron radiation from accelerated particles in the current sheet produces hot secondary pairs in the upstream, which are later advected into the current sheet where they are reaccelerated and produce more photons. In the optically thin regime, when most of the radiation is leaving the upstream unaffected, this process is self-regulating and depends only on the background magnetic field and the optical depth of photons to pair production. The extra plasma loading also affects the properties of reconnection. We study how the inflow of the secondary plasma, with multiplicities up to several hundred, reduces the effective magnetization of the plasma, suppressing the acceleration and thus decreasing the high-energy photon spectrum cutoff. This offers an explanation for the weak dependence of the observed gamma-ray cutoff in pulsars on the magnetic field at the light cylinder.
