Published: May 2019

Production of orhtophoto maps from UAV-photogrammetry method depend on aerial data and control points that are measured by GNSS method. Quality control of orhtophoto maps need comparison coordinate from Check Points and orthophoto maps coordinate to calculate the Root Mean Square Error (RMSE). So that, quality of control points is important in aerial data processing. In this research, baseline length, observation time, measurement method, and area characteristics will be discussed based on the GNSS concept to fulfill the accuracy standard of control points from the American Society of Photogrammetry and Remote Sensing (ASPRS). The shorter baseline length, and the loner observation time, accuracy should be increase significantly, but it depends on the field situation and the accuracy required for the user. After all, the result of this research is to obtain control points design based on GNSS concept in Ciwidey Village, Bandung Regency

The Global Navigation Satellite System (GNSS) has been used widely for hazards monitoring, such as landslide or material displacement on the slope due to its high accuracy and precision positioning. However, to assure its accuracy and precision, a further data quality and site assessment must be taken into account. In such a way, it is possible to determine whether the site monitoring is moved or not. Six location of GNSS observation points were established based on the geological structure and the terrain slopes. Satellite visibilities analysis, multipath analysis, and kinematic precise point positioning analysis were performed to assess the GNSS data quality and the monitoring stability. These procedures will determined the further processing scheme for each site monitoring. Some of areas experience the indication of cracks in road and building construction, which lead into an assumption of the displacement has been accumulated in a sub meter fraction. Thus, accounting all of those aspects, first adjustment data processing was implemented to achieve the preliminary results of the first observation.

Published: May 2019

Increasingly, safety and liability critical applications require GNSS-like positioning metrics in environments where GNSS cannot work. Indoor navigation for the vision impaired and other mobility restricted individuals, emergency responders and asset tracking in buildings demand levels of positioning accuracy and integrity that cannot be satisfied by current indoor positioning technologies and techniques. This paper presents the challenges facing positioning technologies for indoor positioning and presents innovative algorithms and approaches that aim to enhance performance in these difficult environments. The overall aim is to achieve GNSS-like performance in terms of autonomous, global, infrastructure free, portable and cost efficient. Preliminary results from a real-world experimental campaign conducted as part of the joint FIG Working Group 5.5 and IAG Sub-commission 4.1 on multi-sensor systems, demonstrate performance improvements based on differential Wi-Fi (DWi-Fi) and cooperative positioning techniques. The techniques, experimental schema and initial results will be fully documented in this paper.
Performance evaluation on GNSS, wheel speed sensor, yaw rate sensor, and gravity sensor integrated positioning algorithm for automotive navigation system
Authors: Han Joong-hee , Park Chi-ho
Published: May 2019

The Global Navigation Satellite System (GNSS) positioning technique is widely used for the automotive navigation system since it can provide the stable and accurate position and velocity in the most road environments at an affordable price. However, the performance of GNSS positioning technique is degraded in certain areas, where GNSS signals are blocked by buildings and tunnel. To overcome this problem, the GNSS positioning technique should be integrated with dead reckoning (DR) sensors such as accelerometer, gyroscope, and odometer. Recently, the most passenger cars are equipped with the Advanced Driver Assistance System (ADAS) based on numerous sensors to improve safety and convenience in driving. Among sensors for the ADAS, vehicle dynamic sensors such as wheel speed sensor (WSS), yaw rate sensor (YRS), gravity sensor (GS) can be used for the DR algorithm since those sensors measure vehicle’s motions. Therefore, this paper evaluates the vehicle positioning algorithm that integrate the GNSS with a three-dimensional dead reckoning based on WSS, YRS, and GS. The vehicle positioning algorithm is implemented through the extended Kalman filter of a loosely-coupled mode. Performance was evaluated through tests carried out in real driving trajectory including various GNSS signals reception environments. It is found that the proposed algorithm can be an alternative solution to compensate the limitation of the GNSS positioning technique, without the use of a low-cost inertial measurement unit.

Published: May 2019

GNSS positioning has become popular in the past decade as an efficient method of precise and real-time positioning. It is relatively low cost and ease-of-use. Up to now, several parameters were defined to characterize the performance of real-time positioning: availability, precision, accuracy. This article evaluates the performance of signal linear combinations for real-time positioning, both for static as well as the kinematic positioning. This article starts with the investigation of linear combinations (LC) rising from the carrier frequencies of the GNSS systems. Some Linear Combination shows potential benefits in carrier phase integer ambiguity resolution, particularly utilizing the Galileo and Beidou signal phase carrier. For each system, a set of combinations was studied, analyzed, and then selected during the development of GNSS positioning method utilizing the Least-squares Ambiguity Decorrelation Adjustment (LAMBDA). Special signal selection can affect the estimated position and its standard deviation. To further analyze, the results obtained from data processing are compared with respect to baselines and signals. The ambiguity fixing rate is correlated with the baseline length and the method as well as the signals that were used. The analysis of the measurement noise level was first conducted to set a baseline for the real-time GNSS positioning application. According to the results and to assess the data quality and positioning performance of GNSS in respect with GPS (Global Positioning System), an experimental test has established using MGEX data. This research investigates the satellite visibilities, multipath, Signal to Noise Ratio (SNR), and positioning performance. It is shown that in every epoch, at least 8 satellites are visible. The SNR’s are up to 60 dBHz, the code multipath residuals varies within ~1 m, while the phase residuals varies by about ~2 cm. hence the modernized GNSS signals have potencies to improves the RTK positioning.

Published: May 2019

This article presents the results of a test carried out to check the usability of spherical TLS targets as GNSS antenna radomes (herein called TLS radomes). On different days, the survey was conducted using two GNSS antennas, one of them with a TLS radome. Measurements were made using 2 roof pillars on the rooftop as base-rover pillars with little obstruction. The measurements were carried out for approximately 1 hour in every scenario. The software used for data processing is MATLAB-based software and the raw data were processed using the double difference (DD) strategy to obtain optimal results. The results of the data processing indicated that the TLS radome has no significant influence on availability and accuracy of estimated position. The signals are slightly attenuated by the radome (1-2 dBHz) and the noise level is slightly increased but both effects are negligible for practical purposes. However, we found that the antenna should be calibrated with the TLS radome to clarify apparent minor phase center eccentricities (1-2 mm) and to reduce systematic effects with long periods (few minutes) and amplitudes up to about 5 mm which are likely due to phase center variations.

Published: May 2019

The Southeast Asia region is mostly surrounded by active subduction zones in which the Australian plate, the Indian plate, and the Philippine Sea plate submerges beneath the continental plates and blocks. The Sunda block covers the large part of the Southeast Asia region, which comprises of Indochina, the South China Sea, the northeastern part of Sumatra, Borneo, the northern part of Java, and the shallow seas in between. We collect the GPS data in the whole Southeast Asia region for the period from 1994 to 2016, and process the original carrier phase data of GPS using GAMIT/GLOBK 10.6 to obtain the velocity field in the International Terrestrial Reference Frame, ITRF2008. The velocity field thus obtained is utilized to update the Euler rotation parameters of the Sunda block in ITRF2008, and model the long-term slip rates between the adjacent plate and blocks. In this study, we model the Sunda block and the Sumatra block together with the Australian plate by using TDEFNODE. The estimated Euler pole parameters of the Sumatra and Sunda blocks are estimated as their locations at (37.4°S, 106.8°E) and (46.2°N, 89.4°W), respectively, and their angular velocities of 0.371°/Myr clockwise, and 0.327°/Myr counter clockwise, respectively. These parameters result in the slip rate of the Sumatra fault with magnitude of ~9 mm/yr.

Published: May 2019

The abundance of tile waste is used as a material innovation in the manufacture of concrete and paving. However, the results of research done by new researchers mostly only as filler material. The paving block which was added as a cement powder substitution material decreased compressive strength along with the tile waste percentage addition (Ridwan, 2017). Thus, researchers try to optimize tile waste treatment before being used in the paving blocks with raise the fuel temperature up to 900°C to obtain more amorphous pozzoland. Waste tile contains SiO?, CaAl?Si?O8, Fe?O ? and Mg? (SiO 4) on the testing of XRD so compliant as pozzoland material. This research used powder waste as a material of cement substitution with 0%, 5%, 7%, and 10% of cement weight with variation of fuel temperature 750 °C, 800 °C, 850 °C and 900°C. The results showed that by increasing the fuel temperature up to 900°C compressive strength increased by 5.9% and water absorption decreased by 14.5%. However, by increasing the percentage of tile waste, compressive strength decreased up to 7.2%. Testing is supported by the SEM results wich indicate that the greater percentage used then the paving surface is also more hollow.

Published: May 2019

One of the popular recharge systems is a recharge well that directly receive rainwater from the roof of the house. In this study, recharge wells will be introduced and analyzed in a modification of conventional drainage. Area for this research was taken in Kimpulan Village, Sleman, Yogyakarta. Input discharge that enters the recharge well used free-flow formula through holes or pipes. The dimensions of recharge wells followed the Sunjoto’s formula, but with T is the time of concentration, not the duration of the dominant rainfall. The result of this study showed that recharge well reduced the maximum discharge and dimensions of the channel. The reduction depends on the diameter of the connecting pipe, the height difference of the water level, depth of groundwater and permeability of the soil in the area. If a diameter pipe of 20 cm and a height difference of 1 m are used, it reduced the runoff discharge more than 17.3%. For the study area, it was not feasible to build additional recharge wells, because it required a large number of wells, approximately 58 pieces, due to very small soil permeability of 3.5.10-5 m/s.

Authors: Prayudyanto Muhammad Nanang , Tamin Ofyar Z.
Published: May 2019

Urban road pricing involves direct charging of drivers for the use of the road network, usually during peak periods. The main objectives for the introduction of a road pricing scheme, in a congested city network, include reduction of delays, environmental improvement and revenue increase. These objectives are closely associated with the concepts of sustainable mobility in urban areas with respect to social equity, economic efficiency, and environmental responsibility. There have been intensive discussions about sustainable transportation in Indonesia. In tune with the issue of climate change and the decline in the ability to provide fuel, this paper is intended to look at the perspective of road pricing from the standpoint of traffic flow, travel speed, emissions reduction, and energy consumption as well as pricing scheme. As pricing will be imposed for the Moslem community, it should conform with Islamic tax income which is for the benefits of poor, needy and less privileged people in the society. The conclusion drawn is that the frenzied application of road pricing will be able to improve traffic in Greater Jakarta but the sustainability of pricing should be adjusted with Islamic tax income.

Published: May 2019

The earthquake is a serious threat in the field of construction in archipelagic countries like Indonesia. The heavier the building is, the greater the earthquake force produced. Lightweight concrete is a concrete that has a light density and contains lightweight aggregate. According to SNI-03-3449-2002 lightweight concrete has a weight of not more than 1850 kg / m3. The innovations used are not limited to the addition of aluminum powder additives but also the utilization of waste as a concrete material as an alternative in waste utilization. The result of the addition of tile powder used as filler in each variation can not increase the value of compressive strength but all the result of the test object still meet the criteria of light concrete that is under 1850 kg / m3. The increase in compressive strength occurs in variations 3 and 5 but does not exceed variation 1. In the 5x5 cm paste specimen, the material is mixed without the use of aluminum powder, the results are more optimal, the data obtained is more accurate, this is due to the method of making pasta with only cement and tile dust no material is wasted.

Authors: Rahayu Paramita , Rini Erma Fitria
Published: May 2019

The gap in water consumption among urban households remains obvious in most cities in Indonesia. It is particularly the case for high-density urban areas. Dense urban areas and limited availability of water resource position water as a contested resource. Regarding water as a contested resource, this paper aims to identify the socioeconomic determinants influencing levels of water consumption in the urbanized medium-sized city, using the case of Surakarta City. Data were collected by using proportional random sampling. Valid respondents are 356 households out of 400 respondents. Respondents were proportioned according to served and not served by networked water PDAM. The data are analyzed by using multiple regression. The result shows that, with 95 percent significance level, overall, age of head of household, total monthly income, housing type, the number of water source utilized by every household, total number of people in every household, and total person work in every household have simultaneously become factors determining water consumption of households in Surakarta. The socioeconomic variables are able to explain 16 percent of the whole factors determining household water consumption in Surakarta City. Even though many factors remain unexplained, this study reveals several important factors that often cause the marginalization of certain urban communities from appropriate domestic water in a rapidly growing secondary city.

Diese Ergebnisse wurden auch durch die Messungen des transepidermalen Wasserverlusts (TEWL) unterstützt. Die Unterschiede der TEWL-Werte nach 21 Tagen waren signifikant für VC gegenüber SLS (p < 0,0001) und für EPR gegenüber SLS (p < 0,0001), was die Schädigung der Hautbarrierefunktion durch SLS, nicht aber durch EPR zeigt.

Das mögliche Sensibilisierungspotenzial der Testformulierungen nach 21-tägiger okklusiver Applikation wurde unter Verwendung des Challenge-Patch-Tests nach einer Auswaschperiode von 2 Wochen bestimmt. 72 Stunden nach Applikation von EPR wurde lediglich bei einem von 34 Probanden ein schwaches Erythem beobachtet.

Somit zeigten die getestete Schmerzcreme und ihre Cremegrundlage ein sehr niedriges Potenzial für Hautreizungen und Schädigung der Hautbarrierefunktion bei 21-tägiger okklusiver Anwendung. Ferner traten im Verlauf der Studie keine weiteren behandlungsbedingten unerwünschten Ereignisse auf.

Introduction In recent years, cold snare polypectomy (CSP) has increasingly been used over hot snare polypectomy (HSP) for the removal of colorectal polyps (4 – 10 mm in size). However, the optimal technique (CSP vs. HSP), in terms of complete polyp resection and complications, is uncertain. Our aim was to compare incomplete resection rate (IRR) of polyps and complications using CSP vs. HSP.

Methods Randomized controlled studies (RCTs) comparing CSP and HSP for removal of 4 – 10 mm colorectal polyps were considered. Studies were included in the analysis if they obtained biopsy specimens from the resection margin to confirm the absence of residual tissue and reported complications. IRR and complication rate were the outcome measures. Pooled rates were reported as Odds Ratios (OR) or risk difference with 95 % Confidence Interval (CI).

Results In total, three RCTs were included in the final analysis. A total of 1051 patients with 1485 polyps were randomized to either HSP group (n = 741 polyps) or CSP group (n = 744 polyps). The overall IRR did not differ between the two groups (HSP vs. CSP: 2.4 % vs. 4.7 %; OR 0.51, 95 %CI 0.13 – 1.99, P = 0.33, I
2 = 73 %). The HSP group had a lower rate of overall complications compared to the CSP group (3.7 % vs. 6.6 %; OR 0.53, 95 % CI 0.3 – 0.94, P = 0.03, I
2 = 0 %). Polyp retrieval rates were not different between the two groups (99 % vs. 98.1 %).

Conclusion Our results suggest that HSP and CSP techniques can be effectively used for the complete removal of 4 – 10 mm colorectal polyps; however, HSP has a lower incidence of overall complications.

Introduction Ruptures of the extensor pollicis longus (EPL) tendon are a
well-known complication of distal radius fractures (DRF). There are a lot of
suspected mechanisms, including mechanical friction, vascular impairment, injury
associated with reduction, and local adhesion. However, there have been limited
reports about a closed rupture of the EPL tendon associated with a relatively
large, displaced dorsal “beak” fracture fragment. We report about the management
outcomes and clinical significance of closed ruptures of the EPL tendon caused
by a displaced dorsal fracture fragment of beak-like appearance in DRF.

Patients/Material and Methods Our study included 7 cases of a complete
closed rupture of the EPL tendon after open reduction internal fixation. All
cases showed a similar pattern involving a relatively large dorsal beak fragment
originating from Lister’s tubercle, and we treated them with a palmar locking
plate within 7 days from the initial fracture without separate dorsal fragment
management. All patients were diagnosed with a delayed EPL tendon rupture.

Results The study included 5 female and 2 male patients. Mean patient age
was 59 years. In all cases we explored the extensor compartment III to verify
the exact cause of the EPL rupture. Six patients underwent an extensor indicis
transfer and one patient underwent tendon grafting.

Mean fragment width and length were 7.0 mm and 13.3 mm, respectively. The
fragments were dorsally elevated (mean, 2.4 mm) and distally displaced (mean,
3.5 mm). At the last follow-up, the mean DASH score was 4.4. Mean thumb MP joint
flexion and extension were 4 degrees and 62 degrees, respectively.

Conclusion We support the possibility of EPL tendon rupture caused by
displaced sharp Lister’s tubercle fracture fragments.

Einleitung Die thermische Venenablation varikös veränderter Stammvenen der
unteren Extremität ist in Deutschland aufgrund der guten Wirksamkeit,
Anwendungssicherheit und hoher Patientenzufriedenheit eine anerkannte und häufig
durchgeführte Behandlungsmöglichkeit. Zielsetzung der prospektiven
Anwendungsbeobachtung (AWB) war die Untersuchung des Operationserfolges, der
Patientenzufriedenheit und des Auftretens von Nebenwirkungen bei endovenöser
Behandlung der varikös veränderten Vena saphena magna (VSM), Vena saphena parva
(VSP) sowie bei Krossenrezidiven (KR) unter Verwendung der ETQ 360° FUSED
Fiber™.

Material und Methoden Insgesamt wurden 162 varikös veränderte Venen (VSM n
= 76, VSP n = 65, KR n = 25) bei 144 Patienten behandelt und in die AWB
eingeschlossen. Ein duplexsonographisches Follow-up erfolgte nach 10–14 Tagen
sowie 3 Monaten. Die ETQ 360° FUSED Fiber™ hat eine Wellenlänge von 1470 nm bei
einem beam angle von 60°. Für die endovenöse Therapie der VSM und von KR wurde
eine Faser mit einem Faserkerndurchmesser von 600 µm bei einem
Spitzendurchmesser von 1,8 mm und 8 Watt Behandlungsenergie eingesetzt. Zur
Behandlung der VSP wurde ein Faserkerndurchmesser von 400 µm bei einem
Spitzendurchmesser von 1,3 mm und 6 Watt Behandlungsenergie gewählt.

Ergebnisse Alle thermisch behandelten VSM (n = 6) und VSP (n = 65) waren
bei Visite 2 und Visite 3 vollständig verschlossen. In der KR Gruppe (n = 25)
zeigten sich bei Visite 2 Verschlussraten von 96 % und Teilverschlussraten von 4
%. Bei Visite 3 konnten noch Verschlussraten von 80 % und Teilverschlussraten
von 16 % nachgewiesen werden. In 4 % der Fälle kam es zu einer vollständigen
Rekanalisierung. Tiefe Beinvenenthrombosen (TVT) oder Lungenembolien (LE) wurde
in keiner der Kohorten diagnostiziert. 1,4 % der an der VSM behandelten
Patienten gaben bei Visite 3 Sensibilitätsstörungen im Behandlungsareal an, in
der VSP Gruppe waren es 6,15 %. Patienten der KR Kohorte gaben keinerlei
Einschränkungen bezüglich der Sensibilität an. Die Patientenzufriedenheit war in
allen Gruppen sehr hoch, in allen 3 Gruppen verbesserte sich der Venous Clinical
Severity Score (VSCC) signifikant.

Zusammenfassung Die Behandlung der VSM, VSP und von KR mit der ETQ 360°
FUSED Fiber™ ist effizient, komplikationsarm und mit einer hohen
Patientenzufriedenheit assoziiert.
Einfluss des Diabetes mellitus Typ II auf Inzidenz, Mikrobiologie, Verlauf und Prognose des Erysipels
Authors: Eickenscheidt L. , Pönnighaus J.-M. , Kowalzick L.
Published: May 2019

Hintergrund und Fragestellung Die Behandlung des Erysipels, einer klassischen Infektionskrankheit in der Dermatologie, wird durch die Auswirkungen des demografischen Wandels und multimorbidere Patienten zunehmend kompliziert. Es gibt kaum miteinander vergleichbare Daten zu Zusammenhängen zwischen Diabetes mellitus und Erysipelen. Anhand der Patienten des Helios Vogtland-Klinikums Plauen wird die Rolle des Diabetes mellitus als Risikofaktor für die Inzidenz und den Verlauf von Erysipelen untersucht.

Patienten/Methodik In einer retrospektiven Untersuchung wurden 592 Patienten, die in den Jahren 2007 – 2017 stationär behandelt wurden, ausgewertet. Die Einschlusskriterien waren: Alter über 18 Jahre, Antibiose > 5 Tage und Plausibilität der Befunde bei stationärer Aufnahme sowie eine vorliegende Diabetes-Diagnostik bzw. -Behandlung. Mikrobiologische Befunde waren kein Kriterium.

Ergebnisse Durchschnittlich 42 % der stationär behandelten Patienten mit Erysipel waren auch an einem Diabetes mellitus Typ II erkrankt oder hatten einen okkulten Diabetes, während der Anteil von Diabetes-Patienten im Krankenhaus insgesamt nur konstant ca. 20 % betrug (p < 0,001). Ein Wechsel des primär eingesetzten i. v. -Antbiotikums war bei Erysipel-Patienten mit einem Diabetes mellitus Typ II oder einem okkulten Diabetes aufgrund eines Therapieversagens in 46 % der Fälle erforderlich, bei Patienten ohne Diabetes mellitus in 33 % (OR: 1,7, p = 0,005). Eine Sepsis entwickelten 11 % bzw. 4 % (OR: 2,8, p = 0,002) und stationär behandelte Rezidive 19 % bzw. 10 % (OR: 2,0, p = 0,007) der jeweiligen Kollektive mit und ohne gleichzeitigem Diabetes. Bei Patienten mit Diabetes mellitus Typ II zeigte sich ein signifikant besseres Ansprechen auf die Kombination Ceftriaxon/Ciprofloxacin als auf die Monotherapie mit Penicillin G (OR 4,1 [95 % CI 2,1 – 7,6]; p < 0,005).

Schlussfolgerungen Der Diabetes mellitus Typ II stellt bei stationär behandelten Patienten einen Risikofaktor für Inzidenz, Verlauf und Prognose der Erysipel-Erkrankung dar. Stationär behandelte Patienten mit Erysipel sollten ein Diabetes-Screening erhalten. Patienten mit klinischem Erysipel und Diabetes mellitus Typ II profitieren von der leitlinienempfohlenen Standard-Antibiose möglicherweise weitaus weniger als bisher angenommen.
Sarcoma of the Lower Limb: Reconstructive Surgeon's Perspective

Published: May 2019

Management of sarcomas in the lower extremities have evolved from amputations to limb-preserving surgeries with evidence to support that they have equal overall survival, albeit with better functional outcome. The challenge of reconstruction lies in providing a durable, functional, and aesthetically pleasing limb. However, limb-preserving intention should not delay interventions that provide a survival benefit such as chemotherapy and radiotherapy. The advent of radiotherapy and chemotherapy also has implications on wound healing and should be considered during the reconstructive process. This article reviews the methodical approach, reconstructive strategies, and considerations for the reconstructive surgeon with respect to the lower extremity after sarcoma excision.
