Authors: Vianna Humberto Dias , Calliari Lauro Julio
Published: August 2017

O litoral norte do Rio Grande do Sul possui balneários oceânicos distribuídos ao longo de 135 quilômetros. Esse trabalho tem por objetivo caracterizar a sedimentologia, mais especificamente conhecer o tamanho médio do grão e percentuais de areia média, fina e muito fina dos balneários oceânicos dessa região. Amostras georreferenciadas de sedimentos foram coletadas, entre 2015 e 2016, em três ambientes sedimentares: crista da duna frontal, praia subaérea e face da praia, totalizando 303 amostras. As análises mostraram que é possível diferenciar os três ambientes por seus atributos sedimentológicos. Os balneários são constituídos por areias finas unimodais e bem classificadas, com tamanho médio de 2,42 ?. Os percentuais médios são: 10,24% (areia média) 86,27% (areia fina), 3,35% (areia muito fina). Há um aumento no tamanho médio do grão e percentual de areia média das dunas frontais em direção à face da praia. As amostras das dunas apresentaram as maiores quantidades de areias finas e menor tamanho médio do grão. Quanto aos percentuais de areia muito fina, há um aumento das dunas frontais para a face da praia no trecho entre Cidreira e Tramandaí, repetindo-se de Capão da Canoa a Terra de Areia. Comportamento inverso foi observado de Osório a Xangri-lá. Entre Arroio do Sal e Torres, o maior percentual de areia muito fina ocorreu na praia subaérea, assim como em Palmares do Sul. Balneário Pinhal tem uma distribuição particular, visto que há menos areia muito fina na praia subaérea. A partir das análises concluiu-se que há dois trechos com características sedimentares semelhantes. Tais segmentos são: Palmares do Sul a Imbé e Arroio do Sal a Torres. Os demais municípios possuem características sedimentares que os diferenciam desses dois

Bank Muamalat Indonesia (BMI with) is the symbol of the birth of the new banking system (GLBT) which gives the alternative regarding financial management in accordance with the Islamic Sharia. The establishment of the theological orientation in addition to BMI, also can not be separated from the calculation (rationality) behavioral economics. In terms of BMI is as an expression of the orientation of worldliness that is powerful enough to provide a secure banking system options.
Analysis using qualitative methods of descriptive-i.e. not limited to at the level of the collection and compiling of data only. But includes also interpretations as to the meaning of the data obtained in an effort to elucidate the socio historical theological against BMI. Thus, BMI as a manifestation of a very important theological orientation, just as important as when the Muslims consider the manifestation of religious orientation embodied in the form of ritual piety (eg: build the mosque, went on Hajj, and so forth). So, in this context the presence of BMI in sociological proves the existence of close relationships (positive correlation) between the doctrines of religion with the actions/behavior of the economic life of the Muslims.

TEACHING ENGLISH GRAMMAR WITH CLT AND EXPLANATION METHOD
Authors: Haryanto Subaidi
Published: August 2017

Teaching English grammar can be taught by some methods. Two of them are communicative language teaching (CLT) and explanation method. Both CLT and explanation method can be used to present the English language materials such as authentic materials, Scrambled sentences, language games, picture strip stories, poems, songs, poetry, map, and role play. Each of them has strength and weakness. Teaching with CLT can make the class become interesting and the student will not get bored. Whereas, by only using the explanation the student will get bored and the teacher as well. In Indonesia CLT is a modified version to adopt teaching English skills such as reading, writing and and speaking. Structural approach is still applied for teaching language elements such as structure/grammar and vocabulary. Explanation method is used to develop reading skill. However, based on the data of test result by the students, the result of explanation technique is more effectively targeted better than CLT.

Abstract

Efforts Muslims to realize the quality of Islamic Education Institutions have long coveted, to be able to give birth to a superior madrasah model that can compete with general education institutions.

Madrasah on behalf of himself as superior schools and madrasah model should be recognized by the government and the public, not by the madrasah / school itself. Because excellence means having a value more than the other schools or Madrasahs, and certainly worth it not only can be seen from the physical aspect, but also other aspects that determine.

Characteristics of a superior madrasah at least has three aspects, 1). Input, how the selection process for potential students is be done. 2) The process, which includes the ability of teachers, adequate facilities learning, curriculum, skill for language of Indonesian, Arabic, and English is absolutely necessary, teaching methods, which make students become active and creative, which is accompanied by freedom in expressing thoughts and imagination, also extar activities program, as well as extensive cooperation network. 3) Out put, an ability of graduates produced deemed superior, when they have been able to develop intellectual, emotional and spiritual potention of where they are located.

Therefore, madrasah should have the advantage to be proud of the school and the community, which includes comparative advantage and competitive advantage.

Spatiotemporal geostatistical modelling of groundwater level variations at basin scale: a case study at Crete's Mires Basin
Authors: Varouchakis Emmanouil A.
Published: August 2017

Spatiotemporal geostatistical analysis of groundwater levels is a significant tool for groundwater resources management. This work presents a valid spatiotemporal geostatistical model for the groundwater level variations of an aquifer in Crete, Greece. The goal of this approach is to accurately map the aquifer level at variable time-steps using joint space–time information. The proposed model applies the space–time ordinary kriging (STOK) methodology using joint space–time covariance functions. A space–time experimental variogram is determined from the monthly groundwater level time-series between the hydrological years 2009 and 2014 at 11 sampling stations. The experimental spatiotemporal variogram is successfully fitted by the product–sum model using a Matérn spatial and temporal function. STOK was used to predict the monthly groundwater level at each sampling station from January to May 2015. Validation results show low prediction errors that range from 0.95 to 1.45 m, while the kriging variance accurately determines the variability of predictions. Maps of groundwater level predictions and uncertainty are developed for significant months of the validation period to assess the aquifer spatiotemporal variability. This work demonstrates that space–time geostatistics can successfully model the spatial dynamic behaviour of an aquifer when the space–time dependencies are appropriately modelled, even for a sparse dataset.
Set pair analysis for karst waterlogging risk assessment based on AHP and entropy weight
Authors: Zeng Jiajun , Huang Guoru
Published: August 2017

Karst waterlogging is a natural disaster that occurs frequently and it adversely affects the social and economic development of affected areas. An analysis of the causes of karst waterlogging with respect to climate and topography can serve as a foundation for disaster assessment and prevention. In this study, a karst waterlogging risk assessment indexing system was established. The system was based on a comprehensive analysis of risk factors, including the severity of the disaster and the vulnerability of the affected area. DeBao County in GuangXi was used as the study area. Nine risk indicators were chosen as evaluation indexes and combination weights were divided into subjective and objective weights based on the analytic hierarchy process (AHP) and entropy weight. A geographical information system (GIS) was applied to help with the calculations of the set pair analysis (SPA) and to pile up the layers of the evaluation indicators. Then, a risk rating map was drawn using GIS techniques. The results showed that the high risk locations were mainly distributed in the center of DeBao County; therefore, the map could be used as reference for the prevention and management of karst waterlogging risk.
Predicting the impact of heavy groundwater pumping on groundwater and ecological environment in the Subei Lake basin, Ordos energy base, Northwestern China

Published: August 2017

Groundwater is increasingly exploited for energy production in arid areas globally, which will inevitably disrupt the natural equilibrium of groundwater and the ecological environment. A groundwater flow model for Subei Lake basin, Ordos energy base, was developed and calibrated to predict groundwater levels' variation and the impact of heavy groundwater pumping on the ecological environment for the period 2010–2039 under two different pumping scenarios. Results showed that rainfall infiltration and groundwater evapotranspiration were the major source/sink terms for the groundwater system. The obvious groundwater depression cone will be formed in the production field at the end of 30 years and the maximum drawdown will be 11.70 m if the waterworks maintains the present situation. However, recovery of groundwater level will be obvious and the groundwater depression cone will disappear as a result of the implementation of the water diversion project. The increased volume of groundwater pumping between the two scenarios was derived from storage depletion, the activated lateral inflow, the captured groundwater evapotranspiration, lateral outflow and discharge into Subei Lake. Groundwater pumping from Haolebaoji waterworks has caused the decline of the Subei Lake and the noticeable degradation of phreatophyte.

Authors: Tanaka T.
Published: August 2017

In the field of waterworks in urban areas, renewable energy is being utilized through implementing solar power generation in the upper parts of facilities and hydraulic power generation using gravity flow of water and excess pressure. As a result, we have learned that utilization of renewable energy not only decentralizes and diversifies energy supply to enhance reliability and environmental performance but also recovers its costs sufficiently. This paper proposes several utilization models of renewable energy in metropolitan waterworks by presenting installation, maintenance and management of power generation equipment with renewable energy, power generation volume, reduction of CO2 emissions, future plans and further utilization methods.

Published: August 2017

Introduction and Objective: To evaluate the shear bond strength of brackets fixed with different materials (two light-cured nanofilled low-viscosity resins –Transbond Supreme LV and Flow Tain LV and two light-cured traditional resins – Transbond XT and Transbond Plus Color Change) after 10 min and 24 h, and to evaluate the type of failure. Material and methods: Eighty bovine incisors were selected and randomly divided into groups (n = 10) according to the material and fixation period. The brackets were bonded following the manufacturer's instructions and stored in deionized water at 37 oC for  10 min or 24 h. After, the specimens were submitted to shear bond strength test at 0.5 mm/min and evaluated for adhesive remnant index (ARI). The data were submitted to Kruskal Wallis and Wilcoxon tests (p < 0.05) and the ARI scores to Chi-Square test. Results: There was a significant difference among the materials (p < 0.05 (after 10 min – Transbond XT > Transbond Plus Color Change > Transbond  upreme LV = Flow Tain LV and after 24 h – Transbond XT > Transbond Plus Color Change = Transbond Supreme LV =  Flow Tain LV). There was osignificant difference in resistance values between 10 min and 24 h, except for Transbond Plus Color Change. Most groups showed adhesive remaining adhered to the enamel (scores 2 and 3) without statistical significant difference (p > 0.05). Conclusion: The light-cured traditional resins showed higher resistance than the nanofilled materials. The period of fixation had no influence on the resistance for different materials, except for Transbond Plus Color Change.

Published: August 2017

Introduction: The dentigerous cyst, also called a follicular cyst is an odontogenic cyst that develops in association with crown of an impacted tooth, predominantly in mandibular third molars of young patients. The Odontoma is a ectomesenquimal tumor of unknown origin that are more considered developmental malformations (harmatomas) than benign neoplasms. Occasionally, the dentigerous cyst is associated with odontoma. Objective: The article aims to report a case of surgical treatment of dentigerous cyst associated with compound odontoma and unerupted tooth in anterior region of the mandible. Case report: A male patient, 17 years of age, without systemic changes, was sent to the Center for Dental Specialties of Horizonte, Ceará, Brazil, specialty of Oral and Maxillofacial Surgery, for diagnosis and treatment of oral lesions visualized after periapical radiographic examination to determine failed eruption of element 42. Observing the periapical radiograph it was possible to visualize radiopaque lesion suggestive of a compound odontoma and a cystic capsule in association with the element 42. A panoramic radiographwas requested and it was planned a surgical removal of odontoma with curettage of bone cavity and removing the cystic capsule and element 42. There were no significant postoperative complications, the suture removal was performed 7 days after surgery where it was possible to observe a good healing, no swelling and no paresthesia. Conclusion: The treatment of choice is surgical excision of the lesions with the tooth associated to the cyst, it should be performed with proper planning, avoiding injury to vital structures and should not be delayed in order to avoid possible occlusion sequelae.

Introduction:

Cardiovascular diseases (CVD) are becoming more prevalent in HIV-infected populations as they age largely due to improved treatment outcomes. Assessment of CVD risk and CVD risk factors in HIV-positive populations has focused on high income settings, while there are limited studies evaluating CVD in HIV-positive populations in the Asian region.

Materials and Methods:

We provided an overview of the prevalence and incidence of CVD and its risk factors in adult HIV-positive populations, and of the strategies currently in place for CVD management in the Asian region.

Results:

Studies from the Asian region showed that CVD and CVD risk factors, such as dyslipidaemia, elevated blood glucose, obesity and smoking, are highly prevalent in HIV-positive populations. A number of studies suggested that HIV infection and antiretroviral therapy may contribute to increased CVD risk. National HIV treatment guidelines provide some directions regarding CVD risk prevention and management in the HIV-infected population, however, they are limited in number and scope.

Conclusion:

Development and consolidation of guidelines for integrated CVD and HIV care are essential to control the burden of CVD in HIV-positive populations. To inform guidelines, policies and practice in the Asian region, research should focus on exploring appropriate CVD risk screening strategies and estimating current and future CVD mortality and morbidity rates.
Integrated Medical‐Dental Delivery Systems: Models in a Changing Environment and Their Implications for Dental Education
Authors: Jones Judith A. , Snyder John J. , Gesko David S. , Helgeson Michael J.
Published: August 2017

Models and systems of the dental care delivery system are changing. Solo practice is no longer the only alternative for graduating dentists. Over half of recent graduates are employees, and more than ever before, dentists are practicing in groups. This trend is expected to increase over the next 25 years. This article examines various models of dental care delivery, explains why it is important to practice in integrated medical‐dental teams, and defines person‐centered care, contrasting it with patient‐centered care. Systems of care in which teams are currently practicing integrated oral health care delivery are described, along with speculation on the future of person‐centered care and the team approach. Critical steps in the education of dental and other health care professionals and the development of clinical models of care in moving forward are considered. This article was written as part of the project “Advancing Dental Education in the 21st Century.”
Exploring Current and Future Roles of Non‐Dental Professionals: Implications for Dental Hygiene Education
Authors: Maxey Hannah L. , Farrell Christine , Gwozdek Anne
Published: August 2017

The health care system is undergoing transformation in which oral health is not only valued as an aspect of overall health, but health care delivery systems are aligning to better deliver total patient care. As a result of this transformation, education for many non‐dental professionals incorporates oral health content to prepare them to practice in comprehensive delivery models. While some non‐dental professionals already incorporate oral health care in their service, many opportunities exist for expansion of oral health care delivery by other non‐dental professionals, including radiologic technicians, nursing staff, and human services professionals. As non‐dental professionals take on expanded roles in oral health care, the dental hygiene workforce must be prepared to practice in settings with new types of professionals. Dental hygiene curricula should prioritize interprofessional education to best prepare these students for practice in evolved delivery models. This article was written as part of the project “Advancing Dental Education in the 21st Century.”
Enhancing Dental Students’ Understanding of Poverty Through Simulation
Authors: Lampiris Lewis N. , White Alex , Sams Lattice D. , White Tiffany , Weintraub Jane A.
Published: August 2017

Dental students should develop an understanding of the barriers to and frustrations with accessing dental care and maintaining optimal oral health experienced by persons with limited resources rather than blaming the patient or caregiver. Developing this understanding may be aided by helping students learn about the lives of underserved and vulnerable patients they will encounter not only in extramural rotations, but throughout their careers. The aim of this study was to determine if dental students’ understanding of daily challenges faced by families with low income changed as a result of a poverty simulation. In 2015 and 2016, an experiential poverty simulation was used to prepare third‐year dental students at one U.S. dental school for their upcoming required community‐based rotations. In 2015, United Way staff conducted the simulation using the Missouri Community Action Poverty Simulation (CAPS); in 2016, faculty members trained in CAPS conducted the simulation using a modified version of the tool. In the simulation, students were assigned to family units experiencing various types of hardship and were given specific identities for role‐playing. A retrospective pretest and a posttest were used to assess change in levels of student understanding after the simulation. Students assessed their level of understanding in five domains: financial pressures, difficult choices, difficulties in improving one's situation, emotional stressors, and impact of community resources for those living in poverty. The survey response rates in 2015 and 2016 were 86% and 74%, respectively. For each of the five domains, students’ understanding increased from 58% to 74% per domain. The majority reported that the exercise was very valuable or somewhat valuable (74% in 2015, 88% in 2016). This study found that a poverty simulation was effective in raising dental students’ understanding of the challenges faced by low‐income families. It also discovered that framing the issues in the context of accessing dental care was important.

The aim of this study was to investigate the extent and forms of predoctoral implant dentistry instruction in North American dental schools and to identify future directions and challenges. The survey collected data on curriculum content, departmental oversight, techniques, and materials, as well as current problems to be solved. The 30‐question survey was sent in 2012 to the dean or administrator in charge of the predoctoral curriculum of all 73 dental schools in the U.S. and Canada at the time; four reminders were sent. Forty‐seven schools responded, for a response rate of 64%. Of the 47 responding schools, 46 (98%) offered didactic instruction (mean of 17 hours); 87% had a laboratory component (mean of 14.46 hours); and 57% had a clinical requirement. In the responding schools, students had an average of 1.85 implant restorative cases and 0.61 surgical cases. Forty‐two of the schools (89%) had implemented observation of implant surgery and/or assisting with implant surgery in their curricula. Major challenges reported in implementing a comprehensive predoctoral implant curriculum included expense of implant systems to the schools and to patients, shortage of predoctoral cases, and lack of curriculum time and trained faculty. These results show that implant education for predoctoral dental students continues to expand, with a trend towards more preclinical exercises and clinical experiences and fewer didactic courses.

Nowadays, interfirm collaboration has become an increasingly popular strategy among many organizations in various industries, in order to remain competitive. Based on the contingency theory, this paper examines the moderating effect of interfirm collaboration on the relationship between Human Resource Management (HRM) practices and organizational performance. Interfirm collaboration refers to the collaboration strategies undertaken by R&D companies, with other companies in similar or diverse functional areas, including R&D, marketing, or manufacturing, to enhance performance.  Using data from 64 R&D companies, the hierarchical regression analyses showed that only collaboration in R&D and functional collaboration in manufacturing significantly moderated the relationship between HRM practices and organizational performance. Overall, the results provided partial support in the domain of the contingency theory. These results, however, are limited by the small sample size, which might have produced non-significant findings. Therefore, the generalization should be taken cautiously. Future research with a larger sample size is needed to confirm the findings.
On the Paradox of Criminal Investigation from the Perspective of One-Dimensional Time
Authors: Zou Yutong
Published: August 2017

This paper conducts a primary explanation of the concept of paradox of criminal investigation. Besides, it proposes that the very existence of paradox of criminal investigation is due to its one-dimensional time, which meanwhile leads to the indigestibility of the paradox. Therefore, the digestion of paradox of criminal investigation should be abandoned, so as to control the cost brought by it as much as possible.

Shc homology 2–containing inositol 5′ phosphatase-2 (SHIP2) is a lipid phosphatase that inhibits insulin signaling downstream of phosphatidylinositol 3-kinase (PI3K); its role in vascular function is poorly understood. To examine its role in endothelial cell (EC) biology, we generated mice with catalytic inactivation of one SHIP2 allele selectively in ECs (ECSHIP2Δ/+). Hyperinsulinemic-euglycemic clamping studies revealed that ECSHIP2Δ/+ was resistant to insulin-stimulated glucose uptake in adipose tissue and skeletal muscle compared with littermate controls. ECs from ECSHIP2Δ/+ mice had increased basal expression and activation of PI3K downstream targets, including Akt and endothelial nitric oxide synthase, although incremental activation by insulin and shear stress was impaired. Insulin-mediated vasodilation was blunted in ECSHIP2Δ/+ mice, as was aortic nitric oxide bioavailability. Acetylcholine-induced vasodilation was also impaired in ECSHIP2Δ/+ mice, which was exaggerated in the presence of a superoxide dismutase/catalase mimetic. Superoxide abundance was elevated in ECSHIP2Δ/+ ECs and was suppressed by PI3K and NADPH oxidase 2 inhibitors. These findings were phenocopied in healthy human ECs after SHIP2 silencing. Our data suggest that endothelial SHIP2 is required to maintain normal systemic glucose homeostasis and prevent oxidative stress-induced endothelial dysfunction.
Amelogenesis Imperfecta: Case Study
Authors: Leevailoj C , Lawanrattanakul S , Mahatumarat K
Published: August 2017

Amelogenesis imperfecta (AI) refers to a group of rare genetic disorders that involve tooth development and that are passed down through families as a dominant trait. This condition is characterized by abnormal enamel formation caused by gene mutations that alter the quality and/or quantity of enamel. This dental problem can impact both primary and permanent dentition, varies among affected individuals, and results in esthetic and functional problems. This condition caused the patient in the current case report to have a lack of confidence when speaking.

The treatment for amelogenesis imperfecta depends on the severity of the problem and age of the patient. It is crucial to plan a proper remedy, which requires collaboration among dental specialties to execute comprehensive dental treatment in order to provide a long-term solution with adequate esthetics.

The current clinical study presents a patient affected by AI that was diagnosed when the patient was a child. The interdisciplinary treatment continued throughout his childhood and into adult life. The initial treatment consisted of resin composite veneers and stainless-steel crowns to restore the defective tooth structure. The malocclusion of the patient was corrected using a fixed orthodontic appliance that was placed when he had an entire permanent dentition. The treatment plan was eventually intended to include all ceramic crowns and veneers.
Sudden Onset of Subcutaneous Air Emphysema After the Application of Air to a Maxillary Premolar Located in a Nonsurgical Field

Published: August 2017

Although rare, subcutaneous air emphysema can occur during dental procedures such as endodontic treatment, surgical extractions, and preparing a tooth for an indirect or direct dental restoration. We report the development of a subcutaneous air emphysema that was introduced through the periodontal ligament of an untreated premolar after the use of an air syringe to dry the tooth.

Objectives:

To compare the degree of conversion (DC), depth of polymerization (DP), shrinkage stress (SS), flexural strength (FS), elastic modulus (EM), and bond strength (BS) of a low-viscosity bulk fill resin composite and a paste-like traditional composite.

Methods:

Tetric Evo-Flow Bulk Fill (TBF) and Empress Direct (ED; Ivoclar Vivadent) composites were used. DC (%) and FS/EM (MPa/GPa) were evaluated in bar specimens (7×2×1 mm; n=10) using Fourier-transform infrared spectroscopy and a three-point bending test in a universal testing machine (UTM), respectively. For DP and BS tests, conical cavities (n=10) were prepared in bovine dentin and restored with the composites. DP was analyzed by calculating the bottom-to-top surface microhardness ratio (BTHR), and BS (MPa) was determined by push-out testing in the UTM. SS (MPa) was measured for one increment of TBF and two increments of ED in a UTM attached to an extensometer (n=5). Data were analyzed using Student t-test and analysis of variance (α=0.05).

Results:

TBF presented higher values than ED for DC (85.7±6.6% vs 54.2±4.9%) and BS (0.95±0.70 MPa vs 0.35±0.15 MPa). TBF values were lower than ED values for FS (76.6±16.8 MPa vs 144.9±24.1 MPa) and maximum SS (0.77±0.07 MPa vs 1.07±0.15 MPa). TBF and ED values were similar for BTHR (0.83±0.16 vs 0.84±0.08) and EM (11.5±2.8 GPa vs 12.5±2.6 GPa).

Conclusions:

The physical and mechanical properties of TBF, a bulk fill resin composite, were similar or superior to those of ED, a conventional composite, with the exception of FS measurements.

Published: August 2017

This arcicle describes the use of intelligent algorithms for analysingfield measurement data. The main focus is on describing the generalworkflow and practical issues when the amount of data is ''big''and typical data analysis methods for small data cannot be used. Whenthe amount of data is tens of terabytes, it is no longer fitting tocomputer memory. Data visualization is also challenging: visualizationtools can only render a small fraction of data to computer screenand visual inspecting of the whole dataset is not meaningful at all. Thedata is simply too big. Thus, new approaches to study data are neededwhere the data is processed automatically in calculation clusterswithout manual human work. The basic idea of data mining is to graduallyreduce the amount of data by various techniques, as long as the finaldata contains only information relevant to the research question and insuch a compact form that its viewing from the human point of viewis rational use of time.
