Zusammenfassung
Hintergrund Chirurgische Indikationen zum Nierenerhalt werden aufgrund der rasanten Entwicklung der minimalinvasiven Nierenchirurgie viel breiter gestellt. Die aktuelle Literatur hierzu legt nahe, dass neben der Tumorgröße auch die genaue anatomische Lage des Tumors für die Wahl der bestmöglichen operativen Therapie des Patienten beachtet werden muss. Zur präoperativen Risikoeinschätzung werden häufig 2 Nephrometrie-Scores, der Padua- und der R.E.N.A.L.-Score, erhoben. Zur Frage, welcher Score die nierenerhaltende Operabilität eines Nierentumors am besten einschätzt und intra- oder postoperative Komplikationen besser vorhersagen kann, möchten wir anhand unseres Patientenkollektivs einen Beitrag leisten.
Material und Methoden Patientendaten von 117 Patienten, die sich von 2014 bis 2017 am Universitätsklinikum in Kiel einer Nierenteilresektion haben unterziehen müssen, wurden erfasst. Vorhandene Schnittbildgebung (Computertomografie und Magnetresonanztomografie) wurde retrospektiv nach Kriterien von Padua-, bzw. R.E.N.A.L.- Score ausgewertet. Es wurden die Fälle identifiziert, bei denen im Anschluss an den Versuch einer Nierenteilresektion eine radikale Nephrektomie durchgeführt wurde. Hierzu wurden Gruppenunterschiede in der Höhe der beiden Scores statistisch ausgewertet. Wir führten die Korrelationsanalysen zwischen der Höhe der beiden Scores und der Operationsdauer, intra- und postoperativen Komplikationen sowie Gesamtkomplikationen durch.
Ergebnisse Für den R.E.N.A.L-Score zeigten sich signifikant höhere Werte der Tumore (Mittelwertsdifferenz 1,059, p < 0,05), die im Anschluss an den Versuch einer Nierenteilresektion doch durch eine radikale Nephrektomie behandelt werden mussten (10 von 117). Zu beiden Scores konnte eine positive Korrelation mit OP-Dauer (für R.E.N.A.L.-Score: Korr.-Koeffizient 0,284, p < 0,05; für Padua-Score: Koeffizient 0,312, p < 0,05), intra- und postoperativen sowie Gesamtkomplikationen (für R.E.N.A.L.-Score: Korr.-Koeffizient 0,216, p < 0,05; für Padua-Score: Koeffizient 0,192, p < 0,05) gezeigt werden.
Schlussfolgerung Beide Scores dienen der Risikoeinschätzung vor Nierenteilresektion. Für unsere Patienten hätte die Anwendung des R.E.N.A.L.-Scores Vorteile geboten. Eine präoperative Nephrometrie ist sinnvoll und sollte neben der subjektiven Einschätzung des Operateurs zur Anwendung kommen. Uns fehlen bislang noch prospektive Studien zu diesem Thema.

Published: June 2019

ZusammenfassungDieser Übersichtsartikel stellt die Ergebnisse verschiedener Behandlungskonzepte für das metastasierte Urothelkarzinom in den letzten fünf Jahrzehnten zusammen. Mit der Einführung von verschiedenen Kombinations-Chemotherapien wurde ab Mitte der 80er Jahre eine signifikante Überlebensverlängerung und potenzielle Heilbarkeit auch fortgeschrittener Erkrankungsstadien in dieser Tumorentität postuliert. Vor zwei Jahren wurden Studiendaten zur Zweitlinientherapie des metastasierten Urothelkarzinoms mit dem PD1-Antikörper Pembrolizumab publiziert, die erstmals einen Vorteil im Gesamtüberleben gegenüber einer konventionellen Chemotherapie mit Paclitaxel, Docetaxel oder Vinflunin zeigen. Aktuell wird in randomisierten Phase-3-Studien der Einsatz von PD-1/PD-L1 gerichteten Substanzen auch in der Erstlinientherapie des metastasierten Urothelkarzinoms untersucht. Dabei werden verschiedene Therapiestrategien verfolgt: Monotherapien mit PD-1/PD-L1-Inhibitoren sowie deren Kombinationen mit CTLA-4-Inhibitoren oder konventioneller Chemotherapie. Es liegen bereits Daten aus einarmigen Phase-2-Studien zur Monotherapie vor. Erste Daten aus randomisierten Studien werden im Laufe des Jahres 2019 erwartet.
Inpatient Communication Networks: Leveraging Secure Text-Messaging Platforms to Gain Insight into Inpatient Communication Systems

Published: June 2019

Objective This study attempts to characterize the inpatient communication network within a quaternary pediatric academic medical center by applying network analysis methods to secure text-messaging data.
Methods We used network graphing and statistical software to create network models of an inpatient communication system with secure text-messaging data from physicians, nurses, and other ancillary staff in an academic medical center. Descriptive statistics about the network, users within the network, and visualizations informed the team's understanding of the network and its components.
Results Analysis of messages exchanged over approximately 23 days revealed a large, scale-free network with 4,442 nodes and 59,913 edges. Quantitative description of user behavior (messages sent and received) and network metrics (i.e., importance of nodes within a network) revealed several operational and clinical roles both sending and receiving > 1,000 messages over this time period. While some of these nodes represented expected “dispatcher” roles in our inpatient system, others occupied important frontline clinical roles responsible for bedside clinical care.
Conclusion Quantitative and network analysis of secure text-messaging logs revealed several key operational and clinical roles at risk for alert fatigue and information overload. This analysis also revealed a communication network highly reliant on these key roles, meaning disruption to these individuals or their workflows could lead to dysfunction of the communication network. While secure text-messaging applications play increasingly important roles in facilitating inpatient communication, little is understood about the impact these systems have on health care providers. Developing methods to understand and optimize communication between inpatient providers might help operational and clinical leaders to proactively prevent poorly understood pitfalls associated with these systems and build resilient and effective communication structures.
Open Hand Prone as a resource in multimodal claims to interruption
Authors: Kamunen Antti 
Published: June 2019

AbstractThis paper examines the Open Hand Prone ‘vertical palm’ as a resource for participants in conversation for displaying their treatment of a co-participant’s – or their own – turn/action as interruptive. Through this practice participants can manage turn-taking by making it relevant for the co-participant to stop talking. The data for this study consist of video-recorded conversations in English and Finnish from domestic and institutional settings, as well as broadcast talk. Using multimodal conversation analysis, this study shows that the gesture occurs in situations involving overlapping/competitive talk or incompatible embodied activities that somehow affect the progressivity of the ongoing talk. This paper complements previous research on gesture studies and interaction by investigating the function these gestures take in stopping/interrupting a co-participant’s turn-at-talk across multiple settings, and by studying how the gesture functions as a part of a practice which has direct social consequences on the local organization of turn-taking.
Periodical codes and translation
Authors: Tahir Gürçağlar Şehnaz 
Published: June 2019

Abstract
This article discusses the relevance of periodical codes, an analytical framework that has been
developing in the nascent field of periodical studies, for translation research. It explores how using periodical codes as
heuristic tools can be instrumental in shedding light on the role of translation in the making of a magazine’s common habitus in a
historical context. It presents a case study on the Turkish literary and cultural magazine Varlık, which began
publication in 1933 and is still in existence. It offers a quantitative and qualitative
analysis on the position of translation in the magazine, highlighting the way it contributed to the creation of particular forms
of internal and external dialogics. Special emphasis is placed on compositional and social codes of Varlık and
the way translation has been instrumental in shaping both.
The use of corpora in legal and institutional translation studies
Authors: Prieto Ramos Fernando 
Published: June 2019

AbstractResearch in legal and institutional translation within the realm of Legal Translation Studies (LTS) has greatly benefited from embracing the advances of Corpus Linguistics in the past few decades. This paper provides an overview of corpus-based approaches in LTS and illustrates their increasing prominence and sophistication through the description of seven selected representative projects, including a wide range of corpus types, translation contexts, legal genres, jurisdictions, sizes and languages. The comparative examination of these studies confirms the relevance of corpus methods for LTS, the need to integrate quantitative and qualitative considerations (crucially including legal parameters) into corpus-building criteria, as well as the correlation between research scope and methodological nuance in ensuring corpus suitability.
Procuração/power of attorney
Authors: Passos e Sousa Marques Afonso Tereza , do Céu Henriques de Bastos Maria 
Published: June 2019

Abstract
This paper presents a contrastive legal and corpus-based linguistic and terminological analysis to translate a
common legal instrument on a global scale, the power of attorney in English or procuração in Portuguese. This
usually takes the shape of a written document, granted before a notary public as required by law, allowing one person to appoint
another person to act on his/her behalf. Civil law and common law systems differ considerably with respect to requirements,
formalities and range of powers permitted. In cross-border transactions, a translation is required to certify the authority given
to third parties who do not speak the language. Bearing this in mind, a comparable corpus of authentic Portuguese and British
texts (from England and Wales, and Northern Ireland) pertaining to this legal genre (12 procurações and 24 PoA)
is analysed to identify its characteristics at functional, situational, thematic, lexical and grammatical levels.
Modular and extensible lesson on optical fibre communication for youths
Authors: Wong Nicholas H L , Tong Amy S K , Posner Matthew T 
Published: June 2019

Abstract
Optical fibre communication enables the global internet, but few youths ever learn about how it works, even at a basic level, until tertiary education. While some middle school curricula might include simple geometrical optics concepts like reflection and refraction, they often lack contextual linkage to worldwide telecommunications. Through our studies, we have found that students are more engaged in the learning process when the material directly relates to real life. To address this gap, and moreover to tackle the issue of the STEM skills shortage, we have designed a self-contained lesson to introduce youths to this topic. It is modularised into three parts, beginning with using light to communicate Morse code, and then covering advanced themes such as multiplexing and fibre guidance based on total internal reflection. The modules can be taught sequentially or individually depending on educational level. They emphasise a more phenomenological than theoretical approach and include hands-on activities using easily obtainable materials. We outline the lesson and pedagogical guidelines for classroom settings, as well as evaluate actual classes run. This lesson can be flexibly implemented in formal classes or through educational outreach programmes.
Simulation of impedance changes with a FEM model of a myelinated nerve fibre
Authors: Tarotin Ilya , Aristovich Kirill , Holder David 
Published: June 2019

Abstract

Objective. Fast neural electrical impedance tomography (EIT) is a method which permits imaging of neuronal activity in nerves by measuring the associated impedance changes (dZ). Due to the small magnitudes of dZ signals, EIT parameters require optimization, which can be done using in silico modelling: apart from predicting the best parameters for imaging, it can also help to validate experimental data and explain the nature of the observed dZ. This has previously been completed for unmyelinated fibres, but an extension to myelinated fibres is required for the development of a full nerve model which could aid imaging neuronal traffic at the fascicular level and optimise neuromodulation of the supplied internal organs to treat various diseases. Approach. An active finite element method (FEM) model of a myelinated fibre coupled with external space was developed. A spatial dimension was added to the experimentally validated space-clamped model of a human sensory fibre using the double cable paradigm. Electrical parameters of the model were changed so that nodal and internodal membrane potential as well as propagation velocity agreed with experimental values. Impedance changes were simulated during activity under various conditions and the optimal parameters for imaging were determined. Main results. When using AC, dZ could be recorded only at frequencies above 4 kHz, which is supported by experimental data. Optimal bandwidths for dZ measurement were found to increase with AC frequency. Significance. The novel fully bi-directionally coupled FEM model of a myelinated fibre was able to optimize EIT for myelinated fibres and explain the biophysical basis of the measured signals.

Authors: Danarianto M D , Saputra M B 
Published: June 2019

Abstract
The occurrence of Gamma Ray Bursts (GRBs) is yet unpredictable. Thus, follow-up observations to find its optical counterpart should be made as quickly as possible after the first detection, as well as kept being monitored on the observable area. In Southeast Asia region, two new robotic 50-cm telescopes system will be placed in Timau National Observatory, East Nusa Tenggara, Indonesia, which has about 70% of clear sky fraction with low-latitude sky coverage. In this manuscript, the possibility of implementing the system for GRB follow-up is discussed, followed by its future prospects as a multi-messenger optical follow-up robotic telescope. The current properties and status of the system are also described.

Published: June 2019

Abstract
Gunma Astronomical Observatory (GAO) is regarded as a pioneer of the public observatories equipped with a large telescope of far beyond one meter class. It was established in 1999 by Gunma prefecture local government. Its main telescope is a 150-cm reflector which has an eyepiece system for the star gazing by public people in addition to advanced measuring instruments such as a very powerful high resolution spectrograph for the scientific research. Using this telescope we have carried out a number of activities and studies in the fields of scientific research, education and public outreach. Many of them were kinds of experimental trials of how to use such a telescope at a public observatory. We present some examples of our experiences in these two decades.
The Measurement of Solar Differential Rotation from Proper Motion of Individual Sunspots
Authors: Permata K , Herdiwijaya D 
Published: June 2019

Abstract
The differential rotation is the result of the interaction between rotation and convection and causes dynamo circulation that affect the cycle of solar activity. Tracer method using features in the photosphere such as sunspot is a simple method to measure the differential rotation. In this study, 98 individual sunspots on January 8 - 22, 2013 and August 25 - September 7, 2013 were used to measure the differential rotation of the Sun. The Sun’s continuum images were obtained from HMI (Helioseismic Magnetic Imager) instrument at SDO (Solar Dynamic Observatory). Coordinate and area of sunspot were measured using ImageJ software and converted to Carrington coordinates. From the measurement, we derived the differential rotation equation, the relation of velocity and area of sunspot, and the relation of sunspot’s velocity and Zurich classification. The differential rotation equation obtained in this study is ω (B) = (14.376 ± 0.04) + (0.6 ± 0.38) sin2B (°/day). For the relation between velocity and area of sunspot, we got the sidereal rotation rate of sunspots with area < 100 pixels2 is about 0.8% higher than sunspots with area > 100 pixels2.
An Application of The Markov Chain Monte Carlo (MCMC) Method to Open Cluster Membership Determination
Authors: Hidayat Y A , Arifyanto M I , Aprilia  , Hakim M I 
Published: June 2019

Abstract
The determination of membership in open clusters will be more difficult than determination membership of the globular clusters. This is due to the location of open clusters which located on the galactic disk. From that location, when observing open clusters, it will be observed foreground and background stars also. Determination of membership in cluster could be done by calculating the probability of a star becoming a cluster member. We used double elliptic bivariate Gaussian function to represent the population of cluster and field stars in the region. The function has eleven parameters and solved by using Markov Chain Monte Carlo (MCMC). The Metropolis-Hastings algorithm is used in this works to obtain the probability of open cluster membership. We used astrometric data from GAIA Data Release 2 for two open clusters which their membership are to be determined i.e. IC 1590 and NGC 2262. Our result is nearly in accordance with the MWSC II catalogue. After the cluster membership is obtained, the physical parameters of the two clusters using isochrones fitting from [1] are the distance(pc) 2200 and 2366, reddening(mag) 0.728 and 0.830, distance modulus(mag) 12.210 and 12.438 also log age 6.895 and 8.995, respectively for IC 1590 and NGC 2262.
An improved technique of finding the coefficient of rolling friction by inclined plane method
Authors: Ciornei F C , Pentiuc R D , Alaci S , Romanu I C , Siretean S T , Ciornei M C 
Published: June 2019

Abstract
During the design process the mechanical engineer faces a challenge: the choice of the tribological parameters. Even most influential technical references offer ranges for the frictional characteristics. An emblematic example is the coefficient of rolling friction (CRF). The handiest solution in establishing the correct value of the CRF for a certain contact is to find it experimentally. One of the methods is the inclined plane manner. The weak point of the method consists in the particularly small values of the slope required to evidence the effect of rolling friction. The present work shows a technique for finding the CRF. The principle of the method consists in considering both the slope of the inclined plane and the torque of rolling friction as unknowns. The two parameters can be established by experimental finding of the acceleration of an axi-symmetric body, both for ascending and descending motions.

Mono-axial tracking system for parabolic trough collector
Authors: Ciobanu D , Enescu M , Jaliu C 
Published: June 2019

Abstract
Increased living standards in the developed countries lead to increased energy consumption. By using renewable energy, the fossil fuel consumption and greenhouse gas effect are reduced. The main source of renewable energy is the sun that can be used to produce the thermal energy or electric energy. The concentrating collectors are used to obtain both heat and electricity. The most common and used concentrating collectors are the parabolic trough collectors due to their advantages, such as: lower price, use of mono-axial tracking systems, simple maintenance. Parabolic trough collectors can have orientation around the N-S axis or E-W axis. In the case of N-S orientation, the angular stroke is higher than 120°, and in case of E-W orientation, the angular stroke that the tracking system has to ensure is less than 100°. The mechanisms used to orientate these collectors are using gears, cam or chain transmission. The paper presents a new type of mono-axial tracking system with linear actuators that has the advantages of assuring the required angular stroke, a high orientation accuracy and lower price.
