Published: March 2019

Penggunaan media online dalam melakukan aktivitas telah semakin marak terjadi pada dinamika masyarakat modern. Salah satu obyek sasaran dalam aktivitas online adalah citra digital. Citra digital ini dapat diperuntukan untuk kalangan terbatas saja sehingga mudah menjadi sasaran oleh peretas, terutama jika data citra digital tersebut bersifat penting. Disinilah kriptografi mengambil peran penting dalam mengamankan citra digital. Dengan menggunakan teknik Vernam Cipher, pesan citra digital dapat diacak dengan kunci yang berbeda untuk setiap karakter, sehingga pesan citra digital hanya dapat dibaca oleh penerima saja. Hasil enkripsi akan menghasilkan citra baru dengan adanya perubahan pada intensitas warna piksel. Dari 12 gambar dengan ukuran kurang dari 100 KB, tingkat keberhasilannya adalah 100%. Algoritma ini sangat cepat, dengan kecepatan enkripsi rata-rata 0,007785 dan dekripsi 0,006903 untuk gambar berformat JPEG dan memiliki ukuran piksel 384x384 Berdasarkan penelitian tersebut maka dapat disimpulkan bahwa Algoritma Vernam Cipher adalah algoritma yang baik dan cepat.

Published: March 2019

Perkembangan jaringan wireless  telah banyak diaplikasikan untuk aplikasi sistem pemantauan kesehatan. Salah satu aplikasi sistem pemantauan kesehatan adalah pendeteksian sinyal detak jantung pasien. Pemantauan kesehatan jantung manusia merupakan hal yang penting untuk peningkatkan keselamatan pasien, terutama orang yang berusia lanjut (lansia). Untuk melakukan pemantauan kesehatan jantung manusia diperlukan karakteristik kesehatan organ tubuh baik pada orang sehat atau orang sakit. Permasalahan yang terjadi saat ini adalah tenaga medis dalam melakukan pemeriksaan atau memantau kondisi kesehatan pasien harus bekerja keras dari ruang satu ke ruang lainnya dan jumlah pasien yang selalu bertambah yang tentunya akan menambah beban dokter atau perawat dalam menangani kondisi pasien. Oleh karena itu diperlukan suatu solusi yang dapat membantu dokter atau perawat dalam memantau perkembangan kesehatan pasien secara terus menerus (real time). Penelitian ini dirancang dan diimplementasikan sistem yang dapat memantau kesehatan jantung pasien berbasis  jaringan sensor nirkabel dengan menggunakan modul sensor electrocardiograph (ECG) yang dipasang pada tubuh pasien dan dikirim melalui protokol zigbee, serta diteruskan ke server. Hasil penelitian menunjukkan bahwa pengambilan data yang dilakukan selama 15 detik pada pasien laki-laki dengan umur 25 tahun adalah 17 kali detak atau 86 bpm. Untuk 884 paket data yang dikirimkan selama 15 menit dimana modul zigbee dapat menangkap seluruh paket data sebesar 4488 byte dan total throughput yang dihasilkan adalah 2,39 kbyte/detik dengan delay rata-rata sebesar 0,24486 detik. Pengukuran jangkauan komunikasi berdasarkan kondisi ruang terbuka dalam waktu 15 detik, dimana posisi modul zigbee akan stabil pada ketinggian diatas 200 cm dengan data yang dikirim akan sama dengan data yang diterima dan nilai throughput  yang dihasilkan sebesar 4,19 kbyte/detik, packet loss sebesar 0 %, delay sebesar 6,667 detik. Untuk pengukuran jangkauan komunikasi berdasarkan kondisi ruang tertutup dimana posisi modul zigbee akan stabil pada ketinggian diatas 100 cm dengan data yang dikirim akan sama dengan data yang diterima dan nilai throughput  yang dihasilkan sebesar 4,27 kbyte/detik, packet loss sebesar 0 %, delay sebesar 6,55 detik.

Authors: Adrian Ronald
Published: March 2019

Seiring bertumbuhnya pengguna internet maka tingkat kompleksitas jaringan yang ada didalamnya juga meningkat, seperti routing. Pada kondisi lain, saat ini tengah berkembang teknologi SDN yang merupakan teknologi jaringan baru yang didalamnya dilakukan pemisahan bagian infrastruktur perangkat jaringan menjadi bagian control plane  dan data plane. Hal tersebut berdampak pada pembuatan kebijakan routing yang dilakukan terpusat melalui kontroler dan dijalankan switch OpenFlow. Pengontrolan jaringan terpusat oleh SDN membuat pengaturan jaringan lebih mudah. Pada makalah ini dilakukan implementasi dan analisis kinerja QoS dan waktu konvergensi dari protokol routing OSPF yang pada jaringan SDN dan konvesional berdasarkan penggunaan dan tanpa penggunaan cost dengan perangkat MikroTik serta RouteFlow. Hal tersebut dikarenakan pada protokol ruting OSPF menggunakan LSA sehingga nilai cost akan menjadi penentu rute yang akan dipilih atau digunakan. Pengukuran didasarkan atas parameter QoS (Delay, PLR, Jitter, dan Throughput) serta waktu konvergensi dengan dialiri traffic background yang bertingkat. Selanjutnya nilai performa dari kedua jenis teknologi, antara konvensional dan SDN dibandingkan. Penelitian ini diharapkan akan dihasilkan keluaran dapat menentukan pilihan terbaik dalam menentukan routing protocol yang digunakan dalam jaringan berdasar parameter yang dihasilkan. Kata Kunci: SDN, Routing Protocol, OSPF, RouteFlow, Cost.

Published: March 2019

Christian education is important in the family and school environment. There is no exception for schools that accept students / students with special needs. However, it should be noted that the teaching and learning process of Christian education often has problems, especially in public schools.

Problems that arise are mainly caused by unpleasant learning conditions, which are caused by not having a permanent learning place. Always moving around, and the place is sometimes not suitable for students to study, such as in a warehouse, in rooms that have never been used, near bathrooms that are not insulated, in the teacher's room, in the library, etc. thus experiencing obstacles in the teaching and learning process. This of course does not meet the maximum yield target.

There are also internal barriers, namely from the students themselves. one of them is disabled children, both physically and mentally. The learning process of disabled children cannot run smoothly due to their disability.

Based on the hypothesis test there is a relationship and influence of "Christian Religious Education (PAK) with Children with Special Needs (ABK) in Understanding the Word of God." From thetable ANOVA, it was concluded that there was a significant effect of Christian Religious Education (PAK) with Children with Special Needs (ABK) in Understanding the Word of God.

Published: March 2019

Death events are often regarded as an adverse event, tiring, painful because death picks up someone you love. When humans are abandoned by loved ones, be they husbands, wives, children, lawyers, friends, friends or extended family because death is certain to be miserable in sadness, so some people consider too much death as a detrimental, tiring, tense or torturous event. It is important to understand that death does not recognize wealth, profession, position, honor. Death picks up humans at a time that can't be realized. Grieving when experiencing death is not the best solution because no one gets up again from death because of sadness. Death also comes without asking for permission from humans, because death is part of life.  But it is important for humans to fully understand that behind the death which is considered as a detrimental, sad, painful thing, there is a great joy awaiting the death of a spirit. This issue will be resolved in this article.

Authors: Ikpe Aniekan Essienubong , Orhorhoro Ejiroghene Kelly , Gobir Abdulsamad
Published: March 2019

This paper is focused on B-pillar design and reinforcement with certain criteria that the final reinforcement design weight does not exceed 6Kg and the maximum displacement must be less than 40mm on the application of 140KN load. Surface welding method was applied on the first and second design while spot welding was used for the third design, whereas, seam welding was applied on the fourth design which happened to have the least maximum displacement, least maximum stress and weight compared to the other designs. The welding methods applied in each of the design gave different displacement values with the fourth design showing the least maximum displacement of 13.8mm and the third design showing highest maximum displacement of 31.9mm, while there was proximity in displacement values obtained for the first design (15.2mm) and second design (16.4mm). Hence, for the purpose of design against unforeseen damages during side collision, auto manufacturers may consider employing seam welding techniques when manufacturing a B-Pillar for occupant safety.

Published: March 2019

Software Reliability Growth Models (SRGMs) are supporting software industries in expecting and scrutinizing quality of software. Numerous SRGMs have been proposed; majority of which concentrate on testing period of software. For testing, domain specific knowledge plays a very crucial role. Based on necessity condition, a set of programmes are in testing phase of software development. “Domain testing is a software technique in which small number of test cases is selected for trial. These sets of testing paths, all of which are to be eventually influenced by designed test cases are called the testing domain which expands with the progress of testing”. Keeping this concept in mind, we propose SRGMs with the concept of testing domain with exponential coverage. Utility of proposed framework has been emphasized in this paper through some models pertaining to different distribution i.e Exponential, Logistic, Weibull and Rayleigh. Moreover, the data analysis is performed to find the estimates of parameters by fitting the models on authentic data sets.

Viability of Anisakis spp. Larvae After Direct Exposure to Different Processing Media and Non-Thermal Processing in Anchovy Fillets
Authors: Šimat Vida , Trumbić Željka
Published: March 2019

Anisakiasis is fish-borne zoonoses caused by nematodes of the genus Anisakis, contracted by the ingestion of live L3 infective larvae through consumption of raw, undercooked or thermally unprocessed seafood products, such as carpaccio, and white marinated and dry-salted anchovies. In order to maintain the organoleptic properties of the product, the freezing of fish prior to processing is often ignored, especially in households, and traditional processing methods are not sufficient to kill Anisakis larvae. In this study, we investigated the survival and resistance of Anisakis spp. larvae in different processing solutions including varying salt and sugar content, lemon juice, acetic acid, alcohol, wine, and apple vinegar. We also performed a viability test of larvae during processing in anchovy fillets. When exposed directly to different NaCl concentrations, larvae were killed after approximately three days in the strongest (35%) and 10 days in the weakest solution (5%). In lemon juice and lemon juice with added acetic acid, the survival of larvae was around 5 days. In intact alcohol vinegar, larvae were killed under less than 48 h, while in the solution with water their resistance was prolonged to almost 40 days. In fillets, larvae showed increased resistance during carpaccio and white wine vinegar marinades and only dry salting was effective in destroying Anisakis spp. larvae.
Two-Dimensional Numerical Study of Seabed Response around a Buried Pipeline under Wave and Current Loading
Authors: Foo Cynthia Su Xin , Liao Chencong , Chen Jinjian
Published: March 2019

The evaluation of the wave-induced seabed response around a buried pipeline has been widely studied. However, the analysis of seabed response around marine structures under the wave and current loadings are still limited. In this paper, an integrated numerical model is proposed to examine the wave and current-induced pore pressure generation, for instance, oscillatory and residual pore pressure, around a buried pipeline. The present wave–current model is based on the Reynolds-Averaged Navier–Stokes (RANS) equation with k - ε turbulence while Biot’s equation is adopted to govern the seabed model. Based on this numerical model, it is found that wave characteristics (i.e., wave period), current velocity and seabed characteristics such as soil permeability, relative density, and shear modulus have a significant effect on the generation of pore pressure around the buried pipeline.
Precipitation of CaCO3 Polymorphs from Aqueous Solutions: The Role of pH and Sulphate Groups
Authors: Cuesta Mayorga Iris , Astilleros José , Fernández-Díaz Lurdes
Published: March 2019

In this work, we aimed to experimentally study the nucleation and growth of CaCO3 phases precipitated from supersaturated aqueous solutions in the presence of varying concentrations of sulphate oxyanion. The experiments were conducted under pH conditions close to neutral (7.6) and by considering a wide range of initial (SO42−)/(CO32−) ratios (0 to approx. 68) in the aqueous solution. We paid special attention to the evolution of the precipitates during ageing within a time framework of 14 days. The mineralogy, morphology, and composition of the precipitates were studied by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and EDX microanalysis. The concentration of sulphate ions in the reacted aqueous solution was studied by ICPs. The experimental results showed that the mineral composition of the precipitate recovered in each run varied with the (SO42−)/(CO32−) ratio in the parental solution, which influenced the mineral evolution of the precipitates during ageing. We observed that high concentrations of sulphate in the aqueous solution stabilized the vaterite precipitates and inhibited calcite formation. Furthermore, aragonite never precipitated directly from the solution, and it was only formed via a dissolution-precipitation process in solutions with a high (SO42−)/(CO32−) ratio after long reaction times. Finally, gypsum only precipitated after long ageing in those aqueous solutions with the highest concentration of sulphate. The reaction pathways during ageing, the morphology of the calcite crystals, and the composition of vaterite and calcite were discussed considering both kinetic and thermodynamic factors. These results showed a considerably more complex behavior of the system than that observed in experiments conducted under higher pHs and supersaturation levels and lower (SO42−)/(CO32−) ratios in the aqueous phase.
Multifunctional miR-155 Pathway in Avian Oncogenic Virus-Induced Neoplastic Diseases
Authors: Bondada Megha Sravani , Yao Yongxiu , Nair Venugopal
Published: March 2019

MicroRNAs (miRNAs) are small noncoding RNAs that fine-tune the responses of the cell by modulating the cell transcriptome and gene expression. MicroRNA 155 (miR-155) is a conserved multifunctional miRNA involved in multiple roles including the modulation of the immune responses. When deregulated, miR-155 can also contribute to cancer as has been demonstrated in several human malignancies such as diffuse large B cell lymphoma, chronic lymphocytic leukemia, as well as in Epstein–Barr virus (EBV)-induced B cell transformation. Avian oncogenic viruses such as Marek’s disease virus (MDV), avian leukosis virus (ALV), and reticuloendotheliosis virus (REV) that account for more than 90% of cancers in avian species, also make use of the miR-155 pathway during oncogenesis. While oncogenic retroviruses, such as ALV, activate miR-155 by insertional activation, acutely transforming retroviruses use transduced oncogenes such as v-rel to upregulate miR-155 expression. MDV on the other hand, encodes a functional miR-155 ortholog mdv1-miR-M4, similar to the miR-155 ortholog kshv-miR-K11 present in Kaposi’s sarcoma-associated herpesvirus (KSHV). We have shown that mdv1-miR-M4 is critical for the induction of MDV-induced lymphomas further demonstrating the oncogenic potential of miR-155 pathway in cancers irrespective of the diverse etiology. In this review, we discuss on our current understanding of miR-155 function in virus-induced lymphomas focusing primarily on avian oncogenic viruses.

Published: March 2019

In acute pancreatitis (AP), kidney injury (KI) can occur. Urinalysis and some urinary biomarkers have been proposed as prognostic tools in human AP. The aim of the study was to evaluate urinalysis and urinary GGT-to-urinary creatinine (uGGT/uCr) in canine AP and their association with possible outcomes. AP diagnosis was based on clinical and laboratory parameters, abnormal SNAP® cPL™ test and compatible imaging. Urinary KI (uKI) was defined if dogs had urinary casts and/or proteinuria. Dogs (n = 70) were divided in survivors and non-survivors according to the 15-day outcome. Data were analyzed using statistical software. Seventy dogs were retrospectively included, of which 24 dogs (34%) died. uKI was detected in 36 dogs (37%) which was associated with mortality (p = 0.01, Odds ratio (OR) 3.9, 95% CI 1.3–11.56). Non-survivors showed higher dipstick bilirubin levels than survivors (p = 0.0022). By excluding active sediments, urine protein-to-creatinine ratio (UPC) ≥2 was associated with mortality (p = 0.001, OR 47.5, 95% CI 4–571.9). The uGGT/uCr was available in 40 dogs, although no association of this factor with any outcome was found. The UPC ≥2 can be a negative prognostic factor in canine AP and further studies on uGGT/uCr are warranted.

The timing of the Spitzer transit is consistent with the ephemeris measured from the two transits observed previously by the Kepler Space Telescope. The Spitzer observation rules out the existence of transit timing variations (TTVs) on the order of hours to days that are known to exist for other long-period exoplanets. Such TTVs render transit follow-up efforts intractable due to the substantial observing time required and the high risk of nondetection. For Kepler-167e, however, we are now able to predict future transit times through the anticipated era of the James Webb Space Telescope with uncertainties of less than six minutes. We interpret the lack of TTVs as an indication that Kepler-167e either does not have an exterior massive companion or that the gravitational interactions with any companions are below our detection threshold. We also measure Kepler-167e’s 3.6 μm transit depth and use exoplanet and solar system models to make predictions about its transmission spectrum. The transiting nature of Kepler-167e and its similarity to Jupiter make it a unique and exceptional target for follow-up atmospheric characterization. Kepler-167e falls into a truly rare category among transiting exoplanets, and with a precisely constrained transit ephemeris, it is poised to serve as a benchmark in comparative investigations between exoplanets and the solar system.

The Sunshine Vitamin
Authors: Suganthan N.
Published: March 2019

Vitamin D deficiency is the most common nutritional deficiency worldwide, characterized by serum 25(OH)D < 50 nmol/L. It is usually caused by sun avoidance, using sun protection, inadequate dietary and supplementary vitamin D intake, malabsorption syndrome and usage of medications. Most of the patients are asymptomatic; severe and prolonged vitamin deficiency causes rickets and growth retardation in children and osteomalacia, osteopenia and osteoporosis in adults. Vitamin D deficiency and insufficiency are treated with supplementary vitamin D and sensible sunlight exposure.

Dilated Cardiomyopathy (DCM) in adults is mostly an idiopathic disease with a progressive and irreversible course. It usually carries a poor prognosis [1]. Rarely, a reversible metabolic etiology amenable to specific therapy is identified [1]. There are few cardiovascular abnormalities that are commonly encountered in patients with renal impairment; these include LVH, LV dilatation, and LV systolic and diastolic dysfunction [2]. Here, we report a case of 36 year-old female with reversible uremic cardiomyopathy due to obstructive uropathy due to moderately differentiated squamous cell type metastatic cervical carcinoma which completely responded to bilateral ureteric stenting.
Implementation of an Orthopedic Trauma Program to Safely Promote Resident Autonomy
Authors: Yang Brian W. , Waters Peter M.
Published: March 2019

Background 

There is ongoing tension in graduate medical education between progressive resident autonomy with entrustable professional activities and the need for supervision to ensure patient safety.

Objective 

We implemented a pediatric orthopedic surgical trauma safety program that utilized a postcall review conference to provide residents graduated responsibility learning opportunities during overnight trauma call without compromising patient safety.

Methods 

In the program, all orthopedic trauma cases seen in our main tertiary hospital emergency department by the overnight orthopedic resident were reviewed in a case conference. For 1 year, we performed an analysis of all fracture patients who were treated in the emergency department by our orthopedic surgery residents. From June 1, 2016, through June 30, 2017, all care delivery encounters were reviewed for decision-making errors, technical errors, and complication rates. Two resident groups rotated through our institution over the course of the study.

Results 

During the year of analysis, all 1298 fracture patients seen overnight in the main tertiary hospital emergency department were reviewed. From the first to the second halves of their rotations, the rate of resident decision-making errors (3.1% [12 of 385] to 2.3% [9 of 399]) and technical errors (9.1% [35 of 395] to 7.3% [29 of 399]) decreased. Excluding decision-making and technical errors, the complication rate for patients discharged home was 3.4% (27 of 784).

Conclusions 

Residents demonstrated decreased decision-making and technical error rates on overnight call while maintaining low complication rates.
Associations Between In-Hospital Mortality, Health Care Utilization, and Inpatient Costs With the 2011 Resident Duty Hour Revision
Authors: Eid Shaker M. , Ponor Lucia , Reed Darcy A. , Beydoun May A. , Beydoun Hind A. , Wright Scott
Published: March 2019

Background 

The Accreditation Council for Graduate Medical Education (ACGME) has mandated revisions to residents' work hours to improve patient safety and enhance resident education and wellness. The impact on clinical outcomes on a national level is poorly understood.

Objective 

We examined data from before and after the ACGME 2011 duty hour revision and looked for differences between teaching and nonteaching US hospitals.

Methods 

A retrospective observational study of patients admitted to hospitals in the 2-year periods before and after the 2011 duty hour revision was conducted, utilizing a nationally representative data set. We compared patient and hospital characteristics using standardized differences. With nonteaching hospitals serving as the control group, we used multiple group interrupted time series segmented regression analysis to test for postrevision level and trend changes in mortality, length of stay (LOS), and costs.

Results 

We examined more than 117 million hospitalizations. At teaching and nonteaching hospitals, trends in mortality and LOS in prerevision and postrevision periods were not significantly different (all P > .05). A significant monthly reduction in cost per hospitalization was noted postrevision at teaching hospitals (P = .019) but not at nonteaching hospitals (P = .62). In the 2 years following the 2011 revision, there was a monthly reduction in cost per hospitalization (–$52.28; 95% confidence interval –$116.90 to –$12.32; P = .026) at teaching relative to nonteaching hospitals.

Conclusions 

There were no differences in mortality or LOS between teaching and nonteaching hospitals. However, there was a small decrease in cost per hospitalization at teaching hospitals following the 2011 revision.

Morfología de la no-narrativa en la animación
Authors: Wazarus Iris
Published: March 2019

La morfología es el estudio de la forma, que permite ubicar, conocer y clasificar nuestro entorno. El objetivo de este texto es explorar la morfología narrativa para poder determinar cómo es la estructura no-narrativa, basada principalmente en Understanding Animation de Paul Wells (2007 [1998]), El Arte Cinematográfico, una Introducción de Bordwell y Thompson (1995 [1979]), y Movement as Meaning in Experimental Cinema de Daniel Barnett (2017 [2008]). Además, se proponen seis diferentes configuraciones que pueden tener las animaciones que no cuentan ninguna historia, partiendo de discursos cinematográficos que desafiaron los cánones narrativos como el Cine-Ojo de Vertov, la música visual, los estructuralistas y el montaje a distancia de Peleshyan.
Cardiovascular Response to Defecating Postures with and without Valsalva Maneuver in Healthy Individuals
Authors: Bhagat Priyanka , Jiandani Mariya , Mehta Amita
Published: March 2019

Aims: To assess the cardiovascular response to defecating postures of bridging and sitting lean forward with and without Valsalva maneuver in healthy individuals.

Study design: Prospective interventional cross-over study in healthy population.

Study material: Stop watch, Rubber tube, Nostril clip, Pillow, Mercury Sphygmomanometer, Cardioscope (Model no.: Iris 50, Maestros company).

Materials and methods: A total of 100 healthy individuals participated in the study. They maintained sitting lean forward and in bridging position for 5 minutes with and without Valsalva maneuver. Valsalva maneuver was performed at 40 mm Hg pressure for 15 seconds. Blood pressure and heart rate were recorded. Mean arterial pressure and rate pressure product were derived.

Data analysis: The data was analyzed using Statistical Package for the Social Sciences v 16. Shapiro–Wilk test was used to test normality, and nonparametric Mann-Whitney test was used with p < 0.05 as statistically significant.

Results: Sitting in lean forward position showed statistical significant increase in heart rate (p < 0.05) compared to bridging position with Valsalva maneuver. There was a significant rise in blood pressure with bridging as compared to sitting lean forward with Valsalva. There was no statistically significant difference in heart rate and blood pressure between sitting lean forward position and bridging position without Valsalva maneuver.

Conclusion: Sitting lean forward position and bridging position increase hemodynamic load compared to relaxed sitting posture. With Valsalva maneuver sitting lean forward posture causes greater rise in heart rate compared to bridging position.
Sirenomelia: A Case Report of a Rare Congenital Anomaly and Review of Literature
Authors: Khan Mohammad , Todase Pallavi
Published: March 2019

Sirenomelia, or the Mermaid Syndrome, is a very rare congenital anomaly. It is associated with varying degrees of fusion of lower limb bones, giving them the appearance of a “mermaid.” It is almost always associated with other birth defects, such as, renal abnormalities, genital anomalies, and cardiac anomalies. We report a case of sirenomelia associated with bilateral multicystic dysplastic kidneys along with bilateral hydronephrosis, severe oligohydramnios, single umbilical artery, absent anal opening, and absent genitals. To the best of our knowledge, this is the first case to be reported from our region.
