Published: March 2018

Aim: To evaluate the bond strength of a GIC associated with chlorhexidine (CHX) to sound and caries-affected dentin, immediately and after six months of storage. Methods: Sixty molars were assigned to two groups of 30 teeth. One had flat dentin surfaces produced and submitted to caries induction to obtain a caries-affected dentin.  In the other group dentin was maintained sound. Teeth of each group were randomly reassigned to three subgroups (n=10) according to the concentration of CHX added to the GIC (0%, 1% and 2% by weight).  Two specimens (1mm diameter x 1 mm high) of the same material were constructed on each dentin surface. One was submitted to the microshear bond strength (µSBS) test after 24 hours and the other after 6 months of storage in water at 37oC. Failure modes were analyzed under a stereomicroscope. Bond strength data were analyzed by three-way ANOVA followed by Games-Howell tests for multiple comparisons, and failure modes by the Chi-square test (α = 0.05). Results: The µSBS values obtained to sound dentin were higher compared with those to caries-affected dentin (p≤0.001). In sound dentin, the group with 2% CHX showed lower  µSBS values compared with 0% and 1% CHX after 24 hours (p=0.005 and p=0.032 respectively). In caries-affected dentin, after 24 hours, µSBS in group with 1% CHX was statistically higher than the values in groups with 2% CHX after 24 hours (p=0.001) and 1% CHX after 6 months (p=0.024). Irrespective of the condition of substrate, comparisons showed no statistically significant differences between the other groups (p≥0.053). Cohesive in material and mixed failures prevailed for all groups. Conclusions: The addition of CHX at concentrations of up to 2% to the GIC did not affect the bond strength of the material to sound and caries-affected dentin in a long-term evaluation.

O Programa Nacional de Alimentação Escolar (PNAE) tem como um de seus objetivos oferecer uma refeição que mantenha a criança alimentada durante a jornada de aula. Um dos problemas que pode prejudicar o alcance dos objetivos nutricionais do programa relaciona-se à sua adesão pelos escolares. Os objetivos do presente estudo foram conhecer a adesão dos alunos ao programa de alimentação escolar, assim como os fatores que podem interferir no consumo dos alimentos oferecidos. Para tanto foi realizada, no ano de 2004, uma pesquisa com 167 alunos do ensino fundamental II de amostra de escolas públicas no município de Toledo – PR. Os resultados mostraram expressiva (77%) adesão dos alunos ao programa e destes, 57% referiram consumir a alimentação escolar de 4 a 5 vezes na semana. Não foi captada associação estatisticamente significativa entre a adesão ao PNAE e as variáveis escolaridade materna, renda familiar e estado nutricional do aluno. Em relação aos fatores que interferem na adesão ao programa, nota-se que algumas preparações oferecidas no cardápio escolar são pouco apreciadas (preparações doces, tipo prato único e sopas). Na opinião da maioria dos alunos, as condições de distribuição da alimentação escolar, com exceção da temperatura do alimento, são adequadas. Entretanto, alguns aspectos podem ser melhorados a fim de contribuir para maior adesão ao programa, em especial aqueles que promovam mudanças no tipo de alimento oferecido e no local para realização das refeições.

Published: March 2018

Desde 1994 o Programa Nacional de Alimentação Escolar – PNAE vem sendo operacionalizado pelos estados e municípios (modelo de autogestão). Nos últimos anos, tendência crescente de adesão de municípios à terceirização do Programa tem sido observada em todas as regiões do Brasil. Esta pesquisa teve como objetivo avaliar os modelos de terceirização e de autogestão do PNAE e identificar as vantagens e desvantagens da sua adoção. A amostra envolveu duas unidades de ensino com jornada de período integral do município de Piracicaba (SP), sendo que em uma das escolas a Prefeitura era responsável pelo PNAE (autogestão) e na outra uma empresa prestadora de serviços de alimentação foi contratada, em caráter experimental. Foi realizado acompanhamento da rotina de execução do PNAE nas escolas, empregando-se roteiros especificamente elaborados para viabilizar a avaliação das condições de preparo e distribuição das refeições, da higiene nas etapas de produção, da adesão e da aceitabilidade dos alunos à alimentação e dos custos do Programa decorrentes dos modelos de gestão. Verificou-se que a aceitabilidade às refeições assemelhou-se à preconizada (85%) pelo Ministério da Educação. Constatou-se que uma das principais dificuldades registradas pelos gestores públicos no que diz respeito à implementação do modelo de terceirização se refere à elaboração de documentos/editais onde constem especificações pormenorizadas dos contratos para prestação desse tipo de serviço. Como vantagem do sistema terceirizado, registra-se a disponibilidade de recursos para manutenção de infraestrutura e equipamentos do PNAE. O custo unitário da refeição distribuída no período do almoço alcançou R$ 1,11 para a empresa terceirizada e R$ 1,37 sob administração da Prefeitura. Não deve ser negligenciado o fato envolvendo o menor custo apresentado pela empresa, que pode ser atribuído à terceirização ter sido realizada em caráter experimental, sendo que a prestação de um serviço de qualidade por um custo reduzido, obviamente seria levada em consideração no processo de decisão da administração pública, no caso da opção, no futuro, recair sobre a gestão terceirizada (para o atendimento dos alunos da totalidade da rede de ensino).

Identity of Ao-Naga and Sümi-Naga Women as Gleaned from Folklores
Authors: Longchar Resenmenla , Kinny H. Salome
Published: March 2018

The word identity has drawn a lot of attention to itself more so in the present age where everyone seems to be in a quest to establish their own identity. This quest for identity is not an alien concept to Naga society which comprises of sixteen officially recognized communities. These communities rely upon their own set of folklores to glean their past. Folklores are a strong medium through which most of the traditional beliefs and cultural practices are embodied. It is a reflection of the past through which the identity of the community can be gleaned. Folklores are not mere spinning of tales to glorify one’s own community, but are narratives of the communities who follow oral-tradition. This paper attempts to glean the identity of Ao-Naga and Sümi-Naga women through their respective folklores. Ao-Naga and Sümi-Naga are two strong communities residing in Nagaland. Both the communities have rich folklores falling into different genres. A striking feature of most folktales is the way details are presented- the name of the village, location and presence of evidence in the present times suggesting the validity of the events in the folktales. After the construction of identity is done, this paper will compare the identity of women of these two communities. Women of both these communities have come a long way from what they were in the past. As the third and final component of this paper, it will analyse whether women are still under grip of their past identity or whether they have moved away from it to build a new identity for themselves in the 21st Century. This paper will further examine the identity of women in the 21st Century in the light of their past as constructed from the folklores.
Analysis of models for viscoelastic wave propagation
Authors: Brown Thomas S. , Du Shukai , Eruslu Hasan , Sayas Francisco-Javier
Published: March 2018

We consider the problem of waves propagating in a viscoelastic solid. For the material properties of the solid we consider both classical and fractional differentiation in time versions of the Zener, Maxwell, and Voigt models, where the coupling of different models within the same solid are covered as well. Stability of each model is investigated in the Laplace domain, and these are then translated to time-domain estimates. With the use of semigroup theory, some time-domain results are also given which avoid using the Laplace transform and give sharper estimates. We take the time to develop and explain the theory necessary to understand the relation between the equations we solve in the Laplace domain and those in the time-domain which are written using the language of causal tempered distributions. Finally we offer some numerical experiments that highlight some of the differences between the models and how different parameters effect the results.
Numerical Modeling of Unstable Waterfloods and Tertiary Polymer Floods Into Highly Viscous Oils
Authors: de Loubens R.. , Vaillant G.. , Regaieg M.. , Yang J.. , Moncorgé A.. , Fabbri C.. , Darche G..
Published: March 2018

The saturation distribution after unstable waterflooding into highly viscous oil may have a decisive effect on the efficiency of tertiary polymer flooding, in particular because of hysteresis effects associated with oil banking. In this work, we model waterflood and tertiary polymer-flood experiments performed on Bentheimer sandstone slabs with heavy oils of approximately 2,000 and 7,000 cp, and compare the numerical results with experimental production, pressure, and X-ray data.

The unstable waterfloods are initially simulated in two dimensions with our parallel in-house research reservoir simulator (IHRRS) using a high-resolution discretization. In agreement with existing literature, we find that Darcy-type simulations dependent on steady-state relative permeabilities—inferred here from a 3D quasistatic pore-network model (PNM)—cannot predict the measured waterflood data. Even qualitatively, the viscous-fingering patterns are not reproduced. An adaptive dynamic PNM is then applied on a 2D pore network constructed from the statistics of the 3D network. If the fingering patterns simulated with this 2D PNM are qualitatively in good agreement with the experimental data, a quantitative match still cannot be obtained because of the limitations of 2D modeling. Although 3D dynamic PNMs at the slab scale would currently lead to prohibitively high computational cost, they have the potential to address the deficiencies of continuum models at highly unfavorable viscosity ratio.

For the tertiary polymer floods characterized by a much more favorable mobility ratio, Darcy-type modeling is applied, and history matching is conducted from the end of the waterfloods. We find that unless hysteresis caused by oil banking is accounted for in the relative permeability model, it is not possible to reconcile the experimental data sets. This hysteresis phenomenon, associated with oil invasion into previously established water channels, explains the rapid propagation of the oil bank. For the considered experiments, a simultaneous history match of good quality is obtained with the production and pressure data, and the simulated 2D saturation maps are in reasonable agreement with X-ray data.

This paper addresses the challenges in modeling highly unstable waterflooding, using both a conventional Darcy-type simulator and adaptive dynamic PNM, by comparing the simulated results with experimental data including saturation maps. It also highlights the important role of relative permeability hysteresis in the tertiary recovery of viscous oils by polymer injection.

The escalated issue is how to acquire an accurate word class labelling in sentence domain. The author would like to propose a method which combine Hidden Markov Model and Rule Based method. The expected outcome in this research is a better accurary in word class labelling, resulted by only using Hidden Markov Model. The labelling results –from Hidden Markov Model– are  refined by validating with certain rule, composed by the used corpus automatically. From the conducted research through some POST document, using Hidden Markov Model, produced 100% as the highest accurary for identical text within corpus. For different text within the referenced corpus, used words subjected in corpus, produced 92,2% for the highest accurary.

Web server plays a vital role on serving requests from clients. As Internet users grows so fast, the request number increases significantly, thus reducing the overall performance of the web server. One solution is to implement a load balancing system.In this paper, we implement load balancing with Linux Virtual Server to distribute the load to several machines within a cluster. We compared Round Robbin and Least Connection algorithm. The study reveals that load balancing using LVS-NAT can double the throughput output compared to single web server, but less significant on response time and CPU utilization. Implementing LVS-NAT using round robbin algorithm is more robust in optimizing the throughput, CPU utilization, and response time compared to least connection.

In 2011, the circulation of SMS spam in Indonesia was rampant. The SMS can contain promotion of a product which is often unsolicited by the recipient or fraud. This is an overlooked issue in Indonesia. But spam has been a very common topic in other countries. To resolve these problems, we need a system that can recognize SMS spam so the SMS can be diverted or marked prior to the user. In this research, we built a system that implementing the Naive Bayesian classifier for classifying SMS spam, so the user can recognize the SMS spam. The result of this research, the system built is able to classify a SMS into categories spam and not spam. Naïve Bayesian classifier can be implemented effectively in the case of SMS spam filtering. The proper use of text preprocessing can improve the performance of this classification system.

The identification of account is a step to keep the important data secure. Nowadays, it can be done by using username and password, but, after see the reality, the using of username and password can’t keep the data secure from the thief. Because of that, the  verification of the characteristic of personal face can be a solution to change the using username and password. The method that can be used for verification is template matching.It is implemented in four features of personal face, such as left eye, right eye, nose and lips. The four images of  each feature will be extracted with wavelet haar method. The feature extraction will be done during template taking process and verification. The result of this research, the result of verification is determined by two factors,  such as the distance between face and web camera is different when the template taking process and the verification process and the diferrent brightness condition when the template taking process and the verification proccess. The threshold value that has been decided is not really able to block the unregistered data.  Then the accuracy of the verification activity is still low and it is still not able yet to identify an account well.

Az iskolai végzettség és a második gyermekvállalás
Authors: Bartus Tamás
Published: March 2018

A korábbi kutatási eredmények szerint a nők iskolai végzettsége és a második gyermekvállalás között U alakú kapcsolat van Magyarországon. Ez a megfigyelés azonban ellentmond az elméleti várakozásoknak és a nemzetközi tapasztalatoknak. Két kérdésre keressük a választ: (1) Hogyan befolyásolja az anya iskolai végzettsége a második gyermekvállalás valószínűségét? (2) Értelmezhető-e a kapcsolat oksági kapcsolatként? Azaz, akkor is fennáll-e a kapcsolat, ha kiszűrjük a minta szelektív összetételéből fakadó torzításokat, az időprés-hatást és a partner iskolai végzettségéből fakadó hatásokat. A kérdéseket az Életünk fordulópontjai panelvizsgálat 1–3. hullámaiból összeállított eseménytörténeti adatbázison vizsgáljuk. A diszkrét eseménytörténeti elemzés során szimultán becslésekkel kontrolláljuk a szelekciós torzítást. Eredményeink megerősítik a korábbi hazai kutatások eredményeit: az iskolázottság és a második gyermekvállalás összefüggése tényleg U alakú. Az összefüggés valódi oksági kapcsolatnak tűnik, mivel az nem magyarázható sem szelekcióval, sem az időprés-hipotézissel, sem a partnerhatás-hipotézissel. Ha a párok iskolai végzettségét összevontan vizsgáljuk, azt találjuk, hogy a második gyermekvállalás valószínűsége egyrészt a legfeljebb 8 általános iskolát végzett nők, másrészt a diplomás párok között a legmagasabb.
Application of GIS-Based Back Propagation Artificial Neural Networks and Logistic Regression for shallow Landslide Susceptibility Mapping in South China-Take Meijiang River Basin as an Example
Authors: Gong Qing-hua , Zhang Jun-xiang , Wang Jun
Published: March 2018

Introduction:

In this study, artificial neural network (ANN) model and logistic regression were applied to analyze susceptibility and identify the main controlling factors of landslide in Meijiang River Basin of Southern China.

Methods:

Methods: Eleven variables such as altitude, slope angle, slope aspect, topographic relief, distance to fault, rock-type, soil-type, land-use type, NDVI, maximum rainfall intensity, distance to river were employed as landslide conditioning factors in landslide susceptibility mapping.

Both landsliding and non-landsliding samples were needed as training data for ANN model. 384 landslides and 380 non-landsliding point with no recorded landslides according to field investigation and survey data were chosen as sample data of ANN model. And ROC curve was applied to calculate the prediction accuracy.

Results:

The validation results showed that prediction accuracy rate of 82.6% exists between the susceptibility map and the location of the initial 384 landsliding samples. However, logistic regression analysis showed that the average correct classification percentage was 75.4%. The prediction results of ANN model in high sensitive zone is more accurate than the logistic regression model.

Conclusion:

Therefore, the ANN model is valid when assessing the susceptibility. The main controlling factors were identified from the eleven factors by ANN model. The slope, rock and land use type appeared to be the main controlling factors in landslide formation process in Southern China.
Modification of Initial Highly Active Antiretroviral Therapy (HAART) Regimen in Paediatric HIV Patients

Published: March 2018

Background:

Treatment options among Human Immunodeficiency Virus (HIV)-infected children are limited as only a few Highly Active Antiretroviral Therapy (HAART) are approved worldwide for paediatric use. Among children, frequent changes in HAART regimen can rapidly exhaust treatment options, and information addressing this issue is scarce.

Objective:

The aim of the study was to determine factors associated with the modification of initial HAART regimen modification among HIV-infected children.

Method:

A retrospective study was performed among HIV-infected children aged 18 and below, that received HAART for at least six months in a tertiary hospital in Malaysia. Factors associated with modification of initial HAART regimen were investigated.

Results:

Out of 99 patients, 71.1% (n=71) required initial HAART regime modification. The most common reason for HAART modification was treatment failure (n=39, 54.9%). Other reasons included drug toxicity (n=14, 19.7%), change to fixed-dose products (n=11, 15.5%), product discontinuation (n=4, 5.6%) and intolerable taste (n=3, 4.2%). The overall mean time retention on initial HAART before regimen modification was 3.32 year ± 2.24 years (95% CI, 2.79–3.85). Patient's adherence was the only factor associated with initial regimen modification in this study. Participants with poor adherence showed a five-fold risk of having their initial HAART regimen modified compared to those with good adherence (adjusted OR [95% CI], 5.250 [1.614 – 17.076], p = 0.006).

Conclusion:

Poor adherence was significantly associated with initial regimen modification, intervention to improve patient's adherence is necessary to prevent multiple regimen modification among HIV-infected children.
