Projection radiography of the ankle; the views used for different indications vary between medical imaging departments

Plain radiographs are used for initial evaluation of many conditions of the ankle. Many different radiographic views are described in positioning textbooks but evidence on which views to use, in which case, is scarce. The aim of this study was to map imaging procedures related to four indications for ankle projection radiography. A questionnaire was sent to all medical imaging departments in Iceland with questions about acquisition technique for ankle radiography views and which views were used for selected indications. Answer was received from 14 of the 28 departments. All departments gave very similar descriptions of the four most common views. In the case of trauma, all but one department used four views but for control of trauma or operation, four different combinations of views were found using from two to four images. For detrition and osteomyelitis, four views were more common in the larger departments but there was not a statistically significant difference. Eight different combinations of the number of views for the four indications were found. The study indicates that there is a need for standardization in image acquisition protocols. More studies are needed to support decisions about how many views are necessary for the most common ankle radiography indications.

Religion and Poverty Reduction: A Case Study of Coastal Communities in Takalar Regency, South Sulawesi

This paper focuses on examining the role of religion in improving the work ethic of fishing communities in Takalar Regency. The approach used in this research is the Socio-theological Approach (Social monotheism). The social theological approach is a method or method used to link the sociological level of religious or divine society in order to analyze and reveal data on the reality under study. The data acquisition technique is to use data collection methods in the form of observation, interviews and documentation. The results of this study indicate that religion (Islam) plays a role in building work ethic. Poverty can make a person disbelieve in his Lord. Islam teaches its adherents to share with those who are entitled in terms of the theological concept of zakat as poverty alleviation and as a means of realizing social welfare. Islam does not close the space for its adherents to achieve economic prosperity. The framework of monotheism in Islamic teachings has outlined social involvement for its followers to always care and help others.

Combination of HBIM and UAV photogrammetry for modelling and documentation of forgotten heritage. Case study: Isabel II dam in Níjar (Almería, Spain)

The Isabel II dam is a monumental hydraulic structure built in the middle of the nineteenth century in Spain. In this study, unmanned aerial vehicle (UAV) photogrammetry was used as a data acquisition technique to carry out a survey of the dam’s current state and its surrounding constructions. The point cloud obtained by the photogrammetric process, together with the collected historical in-formation, served as the basis to generate an historic building information model (HBIM) that is the central core containing all the graphical, structural and archaeological information. The HBIM was validated by means of the As-Built for Autodesk Revit®-FARO® plug-in, and shows the high accuracy obtained with respect to the point cloud. The results show that with this methodology it is possible to obtain models representative of reality with an accuracy of ± 0.05 m. In addition, in order to improve the visualization, texture adjustments are made to obtain a photorealistic rendering of the model.

Non-periodic motion reduction in globoidal cam with roller follower mechanism

Non periodic motion has been investigated using power spectrum analysis of Fast Fourier Transform (FFT), Lyapunov exponent parameter using Wolf algorithm, and Phase-plane mapping. A multi degrees of freedom (spring-damper system) are added at the end of the follower stem to reduce the nonlinear dynamic behavior of the follower. In the experiment setup, data acquisition technique with signal processing approach is used through an infrared camera device to capture the nonlinear dynamic movement of the follower. A numerical simulation is done using SolidWorks software. An OPTOTRAK/3020 with an infrared camera device is used to track the follower position experimentally. The peak of nonlinear response of the roller follower is reduced by (20.89%, 47.76%, 58.2%, and 67.16%) after using multi degrees of freedom systems.

M Model Pembelajaran APPOSITE Berbantuan Video Animasi dalam Meningkatkan Hasil Belajar dan Kemampuan Berpikir Tingkat Tinggi Siswa pada Materi Fluida Statis

Application of learning model APPOSITE (Application of Step Instruction and Elaboration) with animation videos on this research have to purpose a differents enhancement study result and higher order thinking skill (HOTS) student on fluida statis. Research types is pre-experiment with one group pretes-posttes design. research subject is XI MIPA 6 Student of senior high school 1 Pesanggaran Banyuwangi, with one class experiment which choosed by Fisika’s teacher. Acquisition technique data is interview, documentation, pretes, student worksheet, and posttes. Analysis technique data research is use descriptive analysis to know higher order thinking skill, t-test to know enhancement study result of APPOSITE model with videos animation. Subsequently supported with account n-gain from pretes-posttes score experiment class. Based on result this research, APPOSITE learning model with animation video have a good effect and enhancement higher order thinking skill (HOTS) student, and model is effective enough to enhancement study result student. This is also supported of the result n-gain is obtained 0,639.

GROUNDWATER POTENTIALS ESTIMATION USING SELF-POTENTIAL METHOD AS AN EARLY PREDICTION OF LAND SUBSIDENCE IN GAMPONG LENGKONG LANGSA CITY

The Self-Potential (SP) method was used to identify changes in the potential groundwater in the area of Gampong Lengkong, Langsa City. The data acquisition technique was carried out with a fixed base technique with a measurement count of four acquisition line. Research is conducted for two months that July and August are the same in order to monitor the changes in the SP value associated with the change of SP anomaly. Interpretation is done qualitatively and quantitatively. Qualitative interpretation through analysis maps of the isopotential contours compared between the first month and the second month of measurements in the field. The interpretation is quantitatively by assuming the source of the subsurface anomaly fix geometry models of cylinders or sphere is done by the inversion modeling using the Levenberg-Marquardt method. The results showed that there was a reduction in SP value in the second month, indicating the potential shortage of groundwater in the region. The decrease in groundwater potential is also shown in the inversion results where the result of the calculation of SP anomaly source parameters in the first month is estimated to be at 7.77 meters to 11.05 meters below the ground in the monthly measurements second.
