Keamanan jaringan menjadi hal yang penting untuk semua industri dan perusahaan untuk melindungi data dan informasi penting yang berada didalamnnya. Perlindungan keamanan dalam suatu jaringan umumnya berbasis pada keamanan transmisi data yang dibuat dan diaplikasikan untuk membantu mengamankan suatu jaringan tertentu. Untuk lebih mengoptimalkan pengambilan keputusan maka diperlukan sebuah mesin yang mampu berkolaborasi dengan database IDS maupun IPS, sehingga tipikal serangan yang sangat beragam dapat dipetakan dengan lebih optimal. Salah satu database yang mempunyai rule yang sudah ada adalah IPTABLES, hal ini dikarenakan pada IPTABLES terdapat fungsi firewall yang mampu menangani jenis serangan yang berlipat serta masif. Server yang akan digunakan adalah server dengan sistem operasi Linux. Sedangkan database serangan IDS yang digunakan adalah database KDD 99 yang sudah diakui sebagai salah satu database serangan yang sangat kompleks. Dengan pemanfaatan IPTABLES ini maka diharapkan keamanan server akan bisa dimonitor dengan lebih optimal. IPTABLES biasanya digunakan sebagai salah satu firewall yang digunakan pada server.

Published: April 2019

Novel caged nitroxides (nitroxide donors) with near-infrared two-photon (TP) responsive character, 2,2,6,6-tetramethyl-1-(1-(2-(4-nitrophenyl)benzofuran-6-yl)ethoxy)piperidine (2a) and its regioisomer 2b, were designed and synthesized. The one-photon (OP) (365 ± 10 nm) and TP (710–760 nm) triggered release (i.e., uncaging) of the 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) radical under air atmosphere were discovered. The quantum yields for the release of the TEMPO radical were 2.5% (2a) and 0.8% (2b) in benzene at ≈1% conversion of 2, and 13.1% (2a) and 12.8% (2b) in DMSO at ≈1% conversion of 2. The TP uncaging efficiencies were determined to be 1.1 GM at 740 nm for 2a and 0.22 GM at 730 nm for 2b in benzene. The cytocidal effect of compound 2a on lung cancer cells under photolysis conditions was also assessed to test the efficacy as anticancer agents. In a medium containing 100 μg mL−1 of 2a exposed to light, the number of living cells decreased significantly compared to the unexposed counterparts (65.8% vs 85.5%).

Published: April 2019

Background: Efficient delivery of the poorly water-soluble compound sorafenib still poses a challenge to current formulation strategies. To incorporate the lipophilic molecule into biocompatible and biodegradable theranostic nanoparticles has great potential for improving efficacy and safety of cancer therapy.

Results: In this study, sorafenib nanoencapsulation was optimized using poly(D,L-lactide-co-glycolide) and polyethylene glycol-poly(D,L-lactide-co-glycolide) copolymers comparing three different technologies. The particles ranged in size between 220 and 240 nm with encapsulation efficiencies from 76.1 ± 1.7 % to 69.1 ± 10.1 %. A remarkable maximum drug load of 9.0 % was achieved. Finally, a gadolinium complex was covalently attached to the nanoparticle surface transforming the nanospheres into theranostic devices allowing the localization using magnetic resonance imaging.

Conclusion: The manufacture of sorafenib-loaded nanoparticles and the functionalization of the particle surface with a gadolinium complex resulted in a high drug loading, a strong MRI signal, optimal stability features and a sustained release profile.

CONCEPTUAL MODELS OF THE QUALITY CONTROL PROCESS
Authors: Ribikauskas A. , Vasilecas O. , Čaplinskas A.
Published: April 2019

This paper discusses issues of conceptual modelling of the product quality control process. Special attention is paid to the quality inspection. This process can be considered as a kind of product sorting the aim of which is to identify the product quality category. It is supposed that the sorting can be done according to prescriptive norms and standards. The paper considers the specific features of knowledge described by those norms and standards, discusses how to represent this knowledge by a logic program, and proposes a knowledge‐based architecture of the software system that acts as a part of the quality system and implements the product quality inspection process.

Authors: Housten Ashley J. , Hoover Diana Stewart , Correa-Fernández Virmarie , Strong Larkin L. , Heppner Whitney L. , Vinci Christine , Wetter David W. , Spears Claire A. , Castro Yessenia
Published: April 2019

Background:

Low health literacy (HL) is associated with poor health status and outcomes. Racial/ethnic minorities in the United States disproportionately experience low HL and HL-related health disparities. Among Latinos, acculturation is associated with health outcomes, but little is known about the relationship between acculturation and HL.

Objective:

We examined associations of sociodemographic and acculturation variables with English- and Spanish-language HL among 142 bilingual Latino adults with adequate HL.

Methods:

HL was assessed in English using the Rapid Estimate of Adult Literacy in Medicine (REALM) and in Spanish with the Short Assessment of Health Literacy for Spanish-speaking Adults (SAHLSA). Acculturation was assessed using the four subscales of the Multidimensional Acculturation Scale-II. Associations of sociodemographic data and acculturation with HL were examined using linear regression.

Key Results:

Higher education, higher income, higher English proficiency, and lower Latino cultural identification predicted REALM scores (
ps
<.05) in univariate models. When these variables were entered into a single model, only education and Latino cultural identification were associated with REALM scores. In univariate analyses, the following characteristics were associated with SAHLSA scores: female gender, being partnered, higher education, higher income, being non-US born, lower English proficiency, and higher Spanish proficiency (
ps
< .05). Education, being non-US born, English proficiency, and Spanish proficiency were each significant in the multivariate model.

Conclusions:

Results revealed a significant association between acculturation and English- and Spanish-language HL among bilingual Latino adults with adequate HL, suggesting that HL should be assessed in the language in which individuals are most proficient. HL assessed in a nonprimary language may be confounded with language proficiency.

Plain Language Summary:

The results of this investigation revealed a significant association between acculturation and English- and Spanish-language health literacy among bilingual Latino adults. This suggests that health literacy should be assessed in the language in which individuals are most proficient. Health literacy assessed in a nonprimary language may be influenced by language proficiency.
Starless bias and parameter-estimation bias in the likelihood-based phylogenetic method
Authors: Xia Xuhua
Published: April 2019

I analyzed various site pattern combinations in a 4-OTU case to identify sources of starless bias and parameter-estimation bias in likelihood-based phylogenetic methods, and reported three significant contributions. First, the likelihood method is counterintuitive in that it may not generate a star tree with sequences that are equidistant from each other. This behaviour, dubbed starless bias, happens in a 4-OTU tree when there is an excess (i.e., more than expected from a star tree and a substitution model) of conflicting phylogenetic signals supporting the three resolved topologies equally. Special site pattern combinations leading to rejection of a star tree, when sequences are equidistant from each other, were identified. Second, fitting gamma distribution to model rate heterogeneity over sites is strongly confounded with tree topology, especially in conjunction with the starless bias. I present examples to show dramatic differences in the estimated shape parameter Α between a star tree and a resolved tree. There may be no rate heterogeneity over sites (with the estimated Α > 10000) when a star tree is imposed, but Α < 1 (suggesting strong rate heterogeneity over sites) when an (incorrect) resolved tree is imposed. Thus, the dependence of “rate heterogeneity” on tree topology implies that “rate heterogeneity” is not a sequence-specific feature, cautioning against interpreting a small Α to mean that some sites are under strong purifying selection and others not. Thirdly, because there is no existing (and working) likelihood method for evaluating a star tree with continuous gamma-distributed rate, I have implemented the method for JC69 in a self-contained R script for a four-OTU tree (star or resolved), in addition to another R script assuming a constant rate over sites. These R scripts should be useful for teaching and exploring likelihood methods in phylogenetics.
Optimal Broadcast Strategy-Based Producer Mobility Support Scheme for Named Data Networking
Authors: Hussaini Muktar , Awang Nor Shahrudin , Ahmad Amran
Published: April 2019

Named Data Networking is a consumer-driven network that supports content consumer mobility due to the nature of in-network catching. The catching suppressed unnecessary Interest packets losses by providing an immediate copy of the data and consumer-driven nature influencedthe mobile consumer to resend unsatisfied Interest packet immediately after the handoff. Once the producer moves to a new location, the name prefix changed automatically after handoff to the new router or point of attachment. The entire network lacks the knowledge of producer movement unless if the producer announces its new prefix to update the FIBs of intermediate routers. Lack of producer’s movement knowledge causes an increase of handoff latency, signaling overhead cost, Interests packets losses, poor utilization of bandwidth and packets delivery. Therefore, there is needs to provide substantial producer mobility support to minimize the handoff latency, handoff signaling overhead cost, reduce the unnecessary Interest packets loss to improve data packets delivery once a content producer relocated. In this paper, broadcasting strategy is introduced to facilitate the handoff procedures and update the intermediate routers about the producer movement. Hence, analytical investigation result of this paper addresses the deficiency of Kite scheme by minimizing handoff signaling cost and provides data path optimization after the handoff.

Published: April 2019

Named Data Networking (NDN) performs its routing and forwarding decisions using name prefixes. This removes some of the issues affecting addresses in our traditional IP architecture such as limitation in address allocation and management, and even NAT translations etcetera. Another positivity of NDN is its ability to use the conventional routing like the link state and distance vector algorithm. In route announcement, NDN node broadcasts its name prefix which consists of the knowledge of the next communicating node. In this paper, we evaluate the performance of mobility management models used in forwarding NDN contents to a next hop. This makes it crucial to select an approach of mobility model that translates the nature of movement of the NDN mobile routers. A detailed analysis of the famous mobility model such as the Random Waypoint mobility and Constant Velocity were computed to determine the mobility rate of the NDN mobile router. Simulation analysis was carried out using ndnSIM 2.1 on Linux Version 16.1. we build and compile with modules and libraries in NS-3.29. The sample of movement of the mobile router is illustrated and our result present the viability of the Constant Velocity model as compared with the Random Way point.

Le bal des âmes
Authors: Delacroix Dorothée
Published: April 2019

Dans le Pérou d’après-guerre, les récits de revenants constituent un registre discursif permettant de comprendre comment le sens du drame vécu est reconstruit et des responsabilités sont attribuées tout en évitant les dangers du langage politique explicite. L’ethnographie du souvenir des morts et des disparus, menée au sein des sphères familiale et personnelle, permet de mettre en lumière les relations intimes tissées avec les défunts. L’enjeu de leur analyse est de comprendre la manière dont les populations andines ont réagi aux circonstances historiques particulières de la mort de masse et dans quelle mesure elles ont puisé dans les modèles cognitifs préexistants, liés à la conception métaphysique du salut et de l’au-delà. S’appuyant sur les représentations de la malemort, du destin posthume de l’âme et de la damnation des assassins, l’article analyse les différentes catégories d’âmes errantes des morts de la guerre. Il montre quels mécanismes de communication indirecte offre l’existence sociale de ces entités dans un contexte où prédominent silences et secrets collectifs à l’égard du conflit armé et de ses zones grises.

Enterprise resource planning (ERP) system has been acknowledged as a major driver of seamless and integrated operations. Implementing ERP is a challenging task, requiring configuration, migration from legacy systems. Therefore, the successful assimilation of ERP within an organisation requires building the requisite skills and knowledge to support both the implementation and post-implementation challenges. This study investigates the relationships among supervisor support, computer self-efficacy, transfer motivation and training transfer in an enterprise system environment. The sequential mediating effects of computer self-efficacy and transfer motivation was assessed in this study. Data collected from 170 users who previously attended an ERP system training program were analysed in this study using the SPSS version 24 and Hayes Macro Process. Findings from the analysis revealed direct relationships among the variables, and the full mediation effects influence of computer self-efficacy and transfer motivation in the relationship between supervisory support and training transfer.
Revisiting the Holt-Winters' Additive Method for Better Forecasting
Authors: Hansun Seng , Charles Vincent , Indrati Christiana Rini , Subanar
Published: April 2019

Time series are one of the most common data types encountered by data scientists and, in the context of today's exponentially increasing data, learning how to best model them to derive meaningful insights is an important skill in the Big Data and Data Science toolbox. As a result, many researchers have dedicated their efforts to developing time series analysis methods to predict future values based on previously observed values. One of the well-known methods is the Holt-Winters' seasonal method, which is commonly used to capture the seasonality effect in time series data. In this study, the authors aim to build upon the Holt-Winters' additive method by introducing new formulas for finding the initial values. Obtaining more accurate estimations of the initial values could result in a better forecasting result. The authors use the basic principle found in the weighted moving average method to assign more weight to the most recent data and combine it with the original initial conditions found in the Holt-Winters' additive method. Based on the experiment performed, the authors conclude that the new formulas for finding the initial values in the Holt-Winters' additive method could give a better forecasting when compared to the traditional Holt-Winters' additive method and the weighted moving average method in terms of the accuracy level.
A Novel Tool for Configurable Process Evolution and Service Derivation
Authors: Sbai Hanae , El Faquih Loubna , Fredj Mounia
Published: April 2019

In recent years, variability management in business processes is considered a key of reuse. Research works in this field focused mainly on variability modeling and resolution; whereas, evolution has been somehow neglected. In fact, new business requirements may occur, and business processes must evolve in order to meet the new needs. Furthermore, the evolution at business layer represented by configurable processes impact the IT layer represented by services. In this case, it is necessary to synchronize the changes between these two layers. In other words, the alignment of configurable processes and configurable services must occur to maintain an integrated view of an organization. This can be reached by the concept of service-based configurable processes. The study of existing tools in this domain shows the lack of solutions integrating both the evolution management, and the change propagation with respect to the variability. This article aims to represent the CPMEv, a novel tool for evolution management of service-based configurable processes.
Application Of The Criterion Of Links Distribution Between Elements In A Complex System For Evaluation Of Holistic Text Perfection
Authors: Makagonov Pavel
Published: April 2019

It is known that texts can be examined as complex social systems and Zipf's law is used when applied for the evaluation of their perfection. It is proposed to add distribution of links between the objects of the system to the list of perfection criteria of texts viewed as complex systems. An empirical law of syntactic and linking words distribution in texts is also proposed. The examples of complex systems are examined in order to define a mathematical representation of this law. The models of such systems are associated with the graph theory, exchange of messages at internet forums, distribution of urban population across city districts, and transportation networks. At the “engineering level of rigor” it is shown that in these systems, the empirical law of links distribution between the objects has a general mathematical representation. Non-linguistic models are provided to prove the system-wide character of the distribution of links ranks feature, but the models are also suitable for the self-consistent use in the corresponding applications. The golden proportion in the number of syntactic and significant words is proposed as an additional criterion of text perfection. Perfection criteria are useful in the analysis of the quality of texts posted in the internet and in the development of recommendations for the improvement of texts used for school purposes.

Authors: Galli Brian J. , Khizar Aamir
Published: April 2019

In the United States today, there are thousands of miles of an extended network of natural gas pipelines across the nation. Current pipeline explosions and leaks in several regions have challenged the natural gas industry to re-evaluate efforts and to pursue proactive strategies. Safety and the environmental threat has become a primary concern in the United States and around the world, but mostly in cases where natural gases, oil, and other hazardous wastes are intricate. Thus, a significant point in the natural gas pipeline industry that signifies both the economic and social issue is the unplanned pipeline risk. In this article, a quantitative data analysis was performed for Downstate New York companies, Con Edison and National Grid. There, the data from various natural gas pipelines was observed for the trend regarding failing material, failure cause, aging characteristics, and perform a risk assessment to come up with training and risk checklist that could be crucial for risk handling strategies. The statistical analyses of the natural gas pipeline-related incident data for distribution pipelines between 2012 and 2016, which were composed from Pipeline and Hazardous Material Safety Administration (PHMSA) of the United States Department of Transportation (DOT), are compiled. The total miles in the gas distribution pipelines in downstate New York is approximately 48,539 as of 2016. The equipment failure, other incident cause, other outside force, and excavation damages are the leading causes of the pipe-related incidents, which are responsible for over 20% of the total incidents between 2012 and 2016. As a result, a quantitative research methodology has been developed as the suitable approach to achieve risk assessment. Mainly, this approach aims towards risk management in natural gas industry projects using the maximum likelihood method on 70 rupture incidents between 2012 and 2016, which were collected from the PHMSA pipeline incident database. The hypothetical quantitative risk assessment of the gas distribution pipelines are illustrated by combining the statistics of the pipeline rupture incidents, as well as risk assessment performed in the present study.

Published: April 2019

In this article, a decentralized newsvendor model is analyzed in the presence of demand uncertainty, where the retailer wishes to postpone his ordering decision by few days until the most accurate demand information is available. The impact of such order postponement on the equilibrium profits of both manufacturer and retailer with and without a buyback contract is subsequently examined to obtain a range of wholesale prices within which the marginal profits for both manufacturer and retailer which are non-negative. Furthermore, it is observed that the possibility of implementing order postponement is higher when it is done in the presence of a buyback contract as it increases the marginal profits for both manufacturer and the retailer and expands the feasible region of wholesale price, which leads to a provision of higher flexibility for negotiation between the manufacturer and the retailer.

Growth of helical carbon coils can be achieved by sputtered Inconel® 600 films on silicon (Si) substrates followed by thermal chemical vapor deposition (CVD) using acetylene as a carbon source along with the injection of sulfur hexafluoride (SF6). The coils were used to prepare electronic ink for fabrication of flexible room temperature gas sensors. The ink as a sensing film was deposited onto silver-screen printed plastic substrates using a droplet coating technique. Before dripping the sensing film, the coils were purified using oxidation and acid treatments. The purified coils were then dispersed in different solvents such as deionized water (DI water), ethanol and dimethyl sulfoxide (DMSO) for comparisons. The performance of sensors was investigated for its response to ammonia (NH3) and volatile organic compounds (VOCs) including ethanol, methanol, and dimethylformamide (DMF) in concentration of 1000 ppm at room temperature. Because the baseline resistance of sensor falls within the working range (i.e. kΩ), the coils dispersed in DI water are performed to show the highest selectivity and sensitivity to NH3. The sensing mechanism of helically coiled carbon gas sensors has been also discussed based on the reducing reaction process between NH3 and chemisorbed oxygen on the surface of purified carbon coils.

The CrN ceramic thin films were deposited using DC reactive magnetron sputtering system on silicon wafer substrate. Oxidation behavior was carried out in air at evaluated temperatures ranging from 500 °C up to 900 °C for 2 h. The structure and element composition of the films at different thermal annealing temperatures ranging were investigated by X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS), respectively. The oxidation activation energies of the films were calculated using Arrhenius equation. The changes in the crystal structure from CrN to Cr2O3 phase were investigated from XRD results. The accumulation of grains on surface was confirmed by FESEM micrographs. The cross-section analysis showed an apparent columnar feature with dense structure for the film annealed at low temperature, and becomes porous when increasing the annealing temperature. The thickness was increased from 1.43 to 2.67 μm. The EDS studies indicated the existence of Cr, N and O with different elements compositions on the deposited thin films. The oxidation activation energy for the CrN thin films is 124.4 kJ/mol.

This work aims to study the effect of SiO2 and heat treatment temperature in TEOS-SiO2-OTES film on the hydrophobic property and weathering durability. TEOS-SiO2-OTES film was prepared by sol-gel process. Tetraethylorthosilicte (TEOS) and Octyltriethoxysilane (OTES) were used to form the gel. The contents of SiO2 were varied at 0.5% 1% 3% 5% and 10% by weight. The film was deposited on a glass slide by spin coating. The hydrophobic property was studied by FTIR, UV-VIS spectroscopy, SEM, XRD and contact angle. The weathering chamber was used for studying weathering durability. The weathering condition was controlled at 50 oC and 85%RH. Moreover, the chemical resistant was also tested. The study showed that the silica contents affected the surface roughness of film. The surface roughness of film decreased with increasing amounts of SiO2.

Very thin titanium chromium nitride (TiCrN) films with various Ti content were deposited by unbalanced magnetron co-sputtering of Ti and Cr metals. Deposition time was set to 15 min to achieve film thickness ranging from 142 to 190 nm. Silicon wafers and copper grids were used as substrates. The Ti current (ITi) was varied from 0.4 to 1.0 A to achieve the differnt Ti content whereas Cr current (ICr) was fixed to 0.6 A. Effects of the Ti content on structure and morphology of these TiCrN thin films were studied by X-ray diffraction (XRD), transmission electron microscopy (TEM), atomic force microscopy (AFM), field emission scanning electron microscopy (FE-SEM), and energy-dispersive X-ray spectroscopy (EDS). The XRD revealed that the films showed crystalline structure with fcc phase and were formed as TixCr1-xN solid solution with a crystallite size of about 13 nm. The TEM result confirmed that the films were polycrystalline. The AFM images of the films showed dome top characteristic with root-mean-square roughness slightly decreasing from 1.643 to 1.273 nm. FE-SEM cross-sectional images exhibited development of film morphology from columnar structure corresponding to zone 1 of Thornton’s structure zone model to fine structure gradually with the increase of the Ti content.

Titanium dioxide nanoparticle thin films on the glass slide of 5x20 cm2 as substrate were prepared by sparking method. The sparking system was modified by using titanium wires as an anode of 9 pieces and a cathode of 9 pieces which set the gap between the electrodes of 1 mm and connected a high voltage power supply. The sparking method was controlled a surface temperature of substrate as 26, 100 and 150 OC and a sparking time of 1-5 h in air atmosphere. The as-deposited thin films were analyzed by a scanning electron microscope, measured the water contact angle of 180 days and studied the durability of thin films on glass substrate to the drop water. The result indicated that the optimum condition of the as-deposited thin films was shown at the sparking time of 4 h and surface temperature of 150 OC which shown the homogeneity surface, the hydrophilic properties. The water contact angle increased with increasing the sparking time whereas the increasing surface temperature was found the decreasing of water contact angle. The optimum durability of thin films was used a minimum of a standard deviation (S.D.) at 4.27 which calculated from the water contact angle data from 1-180 days.
