Authors: Mjw Endrian , Kusumawaty Jajuk , Nurapandi Adi
Published: April 2020

The Glasgow Coma Scale (GCS) technique, developed since 1974, is used by nurses and other health care professionals to facilitate documentation of the scale-up of consciousness, assessment of consciousness needed in patients with head injuries, intracranial hemorrhage and many more. GCS can be used in many cases in hospitals not only to assess the presence of head trauma but to assess several conditions that require an awareness assessment. GCS is also needed to determine clinical decisions in the emergency department at the hospital. The purpose of the study, assess the ability of emergency nurses who already have training certificates in determining the value of patient awareness in hospitals using GCS neurological assessment and analyze the relationship between nurses who have a minimum training certificate with the ability of nurses to use GCS in the Government General Hospital Emergency Department. The method used is descriptive-analytic with a chi-square relationship test approach with a sample of all emergency nurses as many as 73 people spread across the three hospitals. The sample has nurses’ inclusion criteria who have emergency department training certificates and served in the emergency room. Exclusion criteria were nurses who served structurally (head of the room and deputy head of the room) and were on leave/permission/sick/not on duty. Samples were taken based on total sampling and crosssectional. The results showed that the nurse’s competence in performing GCS techniques was 58.3% in the good category and 41.7% in the poor category based on the mean value, 7.6 of the five cognitive questions and five competency questions in the case. This study also showed that there was no relationship between ownership of emergency nursing competency certificates with nurse competence in GCS indicated by p-value> 0.05. Conclusions GCS is indeed an instrument in assessing decreased awareness and evaluation of medical emergencies but is not affected by competency certificates for nursing.

Population control is very important for individual and national welfare. Although various synthetic contraceptive agents are available, their use is associated with severe side effects. Therefore, an approach is taken to identify new antifertility agents from natural sources. This study was conducted to determine the effect of areca nut extract on estradiol levels and the estrus cycle of female balb / c mice. The experimental animal models used were fifteen adult female balb / c mice, aged 8-12 weeks, weight 20-40 g and induced for 1 week with water extract of areca nut with a dose of 1 g / 200 g body weight of mice (K1), 2 g / 200 g of body weight of mice (K2) and distilled water in the control group (K0). The estrus cycle was identified by a daily assessment of the relative ratio of nucleated epithelial cells, cornified squamous epithelial cells and leukocytes found at the time of vaginal swabs for 15 days continuously. At the proestrus stage blood is taken from the tail. Serum estradiol levels were determined by ELISA technique. There was a decrease in serum estradiol levels in the treatment group 1 (K1) 1.9 times compared to the control group (K0) and decreased estradiol levels in the treatment group 2 (K2) 5.29 times compared to the control group (K0). Changes in the duration of the estrus cycle occurred in treatment group 1 (K1) to be elongated and treatment group 2 (K2) became non-estrus, while the control group (K0) did not change the duration of the estrus cycle (normal). The decrease in serum estradiol levels affects the estrus cycle of mice (P = 0,000). The administration of areca nut extract has the effect of reducing serum estradiol levels and disrupting the duration of the estrous cycle of female balb / c mice. This finding has important implications for the development of contraception in women.

This article studies the electromagnetic properties of composite materials based on hexaferrite powders and a silicone binder. The results of this study are presented. Samples of radiomaterials based on hexaferrite powders Z-, W-, M-type and silicone binder were made. The measurements were carried out in a frequency range from 100 MHz to 18 GHz. The frequency dependencies of complex permittivity and permeability are shown. Based on the data obtained, the electromagnetic response for composites of various thicknesses located in free space and on the metal was calculated. The composite located on the metal, which contains 80 wt.% BaCo0.6Zn1.4Fe16O27 and has a thickness of 2 mm, can reduce the level of reflected radiation by more than 100 times in the frequency range from 12.5 to 18 GHz. A composite material containing 80 wt.% BaCo2.4Ti0.4Fe23.2O41 is effective narrowband absorber (reduces reflection by more than 100,000 times) at a frequency of 11.6 GHz, at a thickness of 2.6 mm.

Published: April 2020

The paper proposes a solution of the issue of extracting textual information from a document image. There are many interesting solutions of this problem thanks to practical applications, such as text recognition, translation, forensics, etc. The quality of the text information of documents converted into images depends on the type of scene (simple or complex), type of digital camera (low-cost devices, mobile devices), the magnitude and direction of illumination, type of substrate (paper, plastic). These points lead to the fact that the automatic extraction of text from the image is extremely difficult.

The paper presents the results of the development of a cloud system for multi-parameter aerodynamic calculations of unmanned aerial vehicles (UAVs). The developed cloud system consists of the following functional parts: web client – provides an access to the computing cloud, allows interactively preparing a task, sending prepared data to a computing cluster, getting and visualizing calculation results; and computing cloud – provides communication with the web client using an open API and manages the computing process. The computing process of the cloud is based on using open technologies of the OpenFOAM software adapted for solving aerodynamics problems. The authors carried out parametric studies of the external flow of UAV at free-stream velocities of 20, 25, 30 m/s with angles of attack from –4 to 12 degrees. It was found that the smallest drag force is observed for 0-3 degrees of the angle of attack of the flying wing, and the best lift to drag ratio is detected for 5 degrees attack angle. For 5 degrees attack angle the lift force is 47 N for an air free-stream velocity 20 m/s, 74 N – 25 m/s, 106 N – 30 m/s.

Published: April 2020

The article deals with the issues of interpolation and extrapolation of video stream frames in real time. Results of research of the method of generation of intermediate frames of a video stream are given. The method is based on the optical flow calculate. The results of comparison of implementations of the method using the Farneback, Brox and Duality based TV-L1 approaches for the calculation of optical flow and CUDA technology are presented. It is shown that the Farneback method best result is gives. The Duality based TV-L1 method shows a smooth and high-quality optical flow, but gives a very slow calculation speed. The Brox method is not suitable at all, since it shows the worst result both in terms of calculation speed and optical flow quality. The results of comparison of implementations based on CUDA and OpenCL technologies are also presented. OpenCL implementations are almost two times slower than CUDA implementation. This leads to the inability to generate frames in 60 FPS in real time even for low resolution images. However, CUDA can work only on NVidia GPU accelerators. In conclusion, the ways of further research on this topic based on the use of deep neural networks are presented.

White rice tip nematodes, Aphelenchoides besseyi, causes gradual yield loss worldwide including in Indonesia. There are no reports regarding yield losses due to this nematode in North Sumatra. This research was conducted to verify the influence of white tip nematodes on the yield of rice cultivar in greenhouse conditions. The experiment was carried out in a Randomized Complete Block Design (RCBD) with 2 factors and four replications. The first factor is rice cultivar (Ciherang, Sintanutr, Pepe, and IPB 3S), and the second factor is the condition of the seeds (naturally infected, uninfected seeds). The results showed that plants with naturally infected seeds decreased the number of tillers and weighed 100 seeds. The number of non-infected puppies is greater than naturally infected seed, but not significantly different at the 5% level.
