The study was intended to determine the growth response of the pepper plant steak due to an extended 3 hours of Tauge extracting with a concentration of 300 ml/l. The design used in this study is a completely random design with a single factory based pattern of P1 (1 hour), P2 (2 hours), P3 (3 hours), P4 (4 hours), P5 (5 hours). Variable observations in this study are the number of shoots (strands), length of shoots (cm2), number of leaves (strands), amount of roots (cm2), length of roots (cm2), fresh shoots (gram), shoots dry weights (gram), root fresh weights (gram), root dry weights (gram), root dry weights (gram). Studies indicate that extended snorting time of pepper on and Tauge extracting gives very real influence to the growth variable of sprouts (50,66%), root length (32,96%), leaves (58,88%), root length (45,14%), root weight (57,72%), shoots (71,43%), shoots dry weight (65,73%). Thus the treatment of Tauge extracts as one of the natural growth regulator plants in seeding with a concentration of 300 m/l water would be best submerged for 3 hours to speed up the growth and remove the roots to achieve the best quality of the steed growth.

The ever-chaning dynamics of tooth growth in children 6–15 years old
was observed over a 9-year as well as the level of dental care the children
received was determined in collaboration with the local school’s dental
personell, The scientific evidence collected in this study showed the
social significance of erecting and maintaining the practice of proper
dental care in the new politico-economic climate. This was confirmed
by the increase in the level of dental care from insufficient (47 %) to
satisfactory (75 %) over the course of 6 years due to the presence of a
dental hygienist as part of the medical personelle in a secondary school.
The level of dental care ranged from 23 % at the age of 6 to 75 % among
graduates (same children) at the age of 17. Annually, routine examinations performed by the dental hygienist at the school covered 92.3 % of
children, as a result of which over 4 years of follow-up (12–15 years old
children) the number of exacerbated tooth decay decreased 3,02 times
and the the prevalence of permanent tooth decay decreased. Objective
performance indicators of the school dental office substantiate the
importance of school dentistry.

РОЛЬ КЛУБНОЙ ДЕЯТЕЛЬНОСТИ В ФОРМИРОВАНИИ У ПОДРОСТКОВ ТОЛЕРАНТНОСТИ К ДЕТЯМ С ОСОБЫМИ ОБРАЗОВАТЕЛЬНЫМИ ПОТРЕБНОСТЯМИ
Authors: Оспанова Я.М.  , Слюсаренко Н.В.
Published: May 2020

В статье показана роль клубной деятельности в формировании у подростков толерантности к детям с особыми образовательными потребностями. Акцентировано, что клуб как институт социализации  воздействует на учащихся разнообразными способами и выполняет целый ряд особых, присущих только ему функций.

Обращено внимание на необходимость правильной организации деятельности клуба, в частности на то, что важным условием является добровольное вступление подростков в клуб, без принуждения взрослыми.

Подчеркнуто, что для успешного достижения цели и задач программы клубной деятельности необходим правильный подход к управлению клубом со стороны педагогов (главные стратегические цели клуба определяют педагоги, а конкретные мероприятия и тактические планы выносятся на Совет клуба и обсуждаются его членами).

Приведены данные об апробации на базе школы-гимназии г. Нур-Султан (Казахстан) программы клубной деятельности по формированию у подростков толерантности к детям с особыми образовательными потребностями. На первом этапе ее реализации был определен уровень толерантности отношения подростков к детям с особыми образовательными потребностями посредством нескольких методов диагностики. Полученные результаты были не утешительными.

Программа клуба включала различные формы и методы работы (беседы, психолого-педагогические тренинги, творческую деятельность, воспитательные и досуговые мероприятия и т. п.) и доказала свою эффективность (произошли изменения в сторону повышения по показателям уровней толерантности). К тому же подростки изъявили желание продолжить работу в клубе.

Констатировано, что формирование у  подростков толерантности к детям с особыми образовательными потребностями в клубной деятельности является целесообразным и приводит к положительным изменениям когнитивного, мотивационного и поведенческого компонентов при совместном взаимодействии в общении, спорте, учении, досуге, различных воспитательных мероприятиях.
Comparative Study of Mud Treating Agents
Authors: John Oloro
Published: May 2020

The right Agents for treating Mud to achieve suitable mud properties was a problem in drilling operations, hence this study was embarked on by using different agents on fresh water drilling fluids while drilling. In this paper, mud treating agents (foreign additives and local additives) on a mud was considered and compared. Two additives (foreign and local additives) were formulated at different concentrations. From the experimental results, for the weighting agent, Barite performed better than Stibnite on mud weight. Also for the pH control additives, NaOH performed better than Burnt Plantain/Banana Peels. While for the viscosifier, CMC performed, while Tapioca causes a rapid increase in plastic viscosity which is undesirable. For Thinners, Trona and Lignosulphate gave same reducing effects, but Trona gave a better maintenance of pH.

Weakly collisional space plasmas are rarely in local thermal equilibrium and often exhibit non-Maxwellian electron and ion velocity distributions that lead to the growth of microinstabilities—that is, enhanced electric and magnetic fields at relatively short wavelengths. These instabilities play an active role in the evolution of space plasmas, as does ubiquitous broadband turbulence induced by turbulent structures. This study compares certain properties of a 2.5-dimensional particle-in-cell (PIC) simulation for the forward cascade of Alfvénic turbulence in a collisionless plasma against the same properties of turbulence observed by the Magnetospheric Multiscale Mission spacecraft in the terrestrial magnetosheath. The PIC simulation is of decaying turbulence that develops both coherent structures and anisotropic ion velocity distributions with the potential to drive kinetic scale instabilities. The uniform background magnetic field points perpendicular to the plane of the simulation. Growth rates are computed from linear theory using the ion temperature anisotropies and ion beta values for both the simulation and the observations. Both the simulation and the observations show that strong anisotropies and growth rates occur highly intermittently in the plasma, and the simulation further shows that such anisotropies preferentially occur near current sheets. This suggests that, though microinstabilities may affect the plasma globally, they act locally and develop in response to extreme temperature anisotropies generated by turbulent structures. Further studies will be necessary to understand why there is an apparent correlation between linear instability theory and strongly intermittent turbulence.

Published: May 2020

We present chemical abundances of red giant branch (RGB) stars in the dwarf spheroidal (dSph) satellite system of Andromeda (M31), using spectral synthesis of medium-resolution (R ∼ 6000) spectra obtained with the Keck II telescope and Deep Imaging Multi-Object Spectrometer spectrograph via the Spectroscopic and Photometric Landscape of Andromeda’s Stellar Halo survey. We coadd stars according to their similarity in photometric metallicity or effective temperature to obtain a signal-to-noise ratio (S/N) high enough to measure average [Fe/H] and [α/Fe] abundances. We validate our method using high S/N spectra of RGB stars in Milky Way globular clusters, as well as deep observations for a subset of the M31 dSphs in our sample. For this set of validation coadds, we compare the weighted average abundance of the individual stars with the abundance determined from the coadd. We present individual and coadded measurements of [Fe/H] and [α/Fe] for stars in 10 M31 dSphs, including the first [α/Fe] measurements for And IX, XIV, XV, and XVIII. These fainter, less massive dSphs show declining [α/Fe] relative to [Fe/H], implying an extended star formation history (SFH). In addition, these dSphs also follow the same mass–metallicity relation found in other Local Group satellites. The conclusions we infer from coadded spectra agree with those from previous measurements in brighter M31 dSphs with individual abundance measurements, as well as conclusions from photometric studies. These abundances greatly increase the number of spectroscopic measurements of the chemical composition of M31's less massive dwarf satellites, which are crucial to understanding their SFH and interaction with the M31 system.
Long-term mark-recapture and growth data for large-sized migratory brown trout (Salmo trutta) from Lake Mjøsa, Norway

Published: May 2020

Long-term data from marked animals provide a wealth of opportunities for studies with high relevance to both basic ecological understanding and successful management in a changing world. The key strength of such data is that they allow us to quantify individual variation in vital rates (e.g. survival, growth, reproduction) and then link it mechanistically to dynamics at the population level. However, maintaining the collection of individual-based data over long time periods comes with large logistic efforts and costs and studies spanning over decades are therefore rare. This is the case particularly for migratory aquatic species, many of which are in decline despite their high ecological, cultural and economical value.

This paper describes two unique publicly available time series of individual-based data originating from a 51-year mark-recapture study of a land-locked population of large-sized migratory brown trout (Salmo trutta) in Norway: the Hunder trout. In the period 1966-2015, nearly 14,000 adult Hunder trout have been captured and individually marked during their spawning migration from Lake Mjøsa to the river Gubrandsdalslågen. Almost a third of those individuals were later recaptured alive during a later spawning run and/or captured by fishermen and reported dead or alive. This has resulted in the first data series: a mark-recapture-recovery dataset spanning half a century and more than 18,000 capture records. The second data series consists of additional data on juvenile and adult growth and life-history schedules from half of the marked individuals, obtained by means of scale-sample analysis. The two datasets offer a rare long-term perspective on individuals and population dynamics and provide unique opportunities to gain insights into questions surrounding management, conservation and restoration of migratory salmonid populations and freshwater ecosystems.

The impact of the budget process on budgetary slack: The moderating role of uncertainty avoidance and individualism
Authors: Mohanna Dima , Sponem Samuel
Published: May 2020

Le slack est l’une des questions les plus controversées dans la recherche sur le budget. La littérature empirique s’intéresse de plus en plus à identifier les conditions dans lesquelles le slack budgétaire est susceptible d’être maîtrisé. La conception du processus budgétaire peut avoir un impact sur le slack, mais plusieurs études suggèrent que cet impact dépend du contexte culturel. Cet article étudie l’impact de la formalisation, de la contrôlabilité et de la culture nationale sur la création du slack budgétaire. À partir des données obtenues de 226 gestionnaires travaillant dans des banques multinationales françaises installées en France et au Maroc, cette recherche montre que la culture nationale a un effet modérateur sur la relation entre la formalisation, la contrôlabilité et la propension à créer du slack budgétaire. Les données collectées montrent ainsi que la formalisation diminue la propension à créer du slack budgétaire au Maroc alors que la formalisation n’a aucun effet sur cette propension en France. La recherche indique également que l’application du principe de contrôlabilité diminue la propension des gestionnaires à créer du slack budgétaire en France, alors que l’application du principe de contrôlabilité n’a aucun effet sur cette propension au Maroc. Les résultats de notre recherche suggèrent que les systèmes de contrôle ont des effets différents sur le niveau du slack budgétaire dans les différentes cultures. Notre étude contribue ainsi aux recherches explorant l’interface entre les systèmes de contrôle et les cultures nationales, en montrant l’importance de la culture nationale pour comprendre la relation entre la formalisation, la contrôlabilité du budget et la création du slack budgétaire par les managers.
L’identité numérique du locuteur dans les échanges professionnels en ligne : le cas du forum médical infirmiers.com
Authors: Qotb Hani
Published: May 2020

Cet article se propose de mettre en relief les particularités de l’identité numérique du locuteur professionnel sur les réseaux sociaux. En soulignant la notion d’identité, nous abordons ses deux principales dimensions qui ont un impact important sur les échanges produits au sein d’un réseau professionnel numérique : l’identité sociale et l’identité discursive. Dans ce contexte, nous nous intéressons également aux particularités technodiscursives du forum qui permettent au locuteur d’élaborer son identité dans le cadre d’une communauté de pratique en ligne. Pour illustrer les nombreux aspects de cette identité numérique professionnelle, nous mettons l’accent sur le forum infirmiers.com qui donne la possibilité aux participants d’échanger sur plusieurs thèmes médicaux (formation, concours, activités, etc.). L’analyse du corpus montre, d’une part, les procédés langagiers et visuels favorisant l’identité sociale du locuteur (pseudonymes, éléments visuels, préférences personnelles, etc.). D’autre part, l’étude de certains messages produits indique les stratégies visant à développer l’identité discursive des participants dans les interactions professionnelles produites en ligne.

The aim of the study reviews online medical services in Malaysia. The paper reviews the improvement in Malaysian Medical services in the past five years. In this paper, we systematically reviewed literature from the year 2014 to 2018. We selected the web of science database for the literature search to make the process more transparent and clearer, every process is recorded on the excel sheets and all studies were screened through rigorous inclusion and exclusion criteria. Final 48 papers were selected for this systematic literature review and all irrelevant papers are excluded from the study. For the selection and exclusion process, PRISMA 2009 is used. The results revealed that Literature is heavily focusing on the medical services towards the urban areas, but rural areas were largely neglected. Many studies are discussing the importance of online medical services; However, implementation mechanisms have not been discussed. The systematic review recommends that future research should be focused more on holistic patterns of implementations of the online medical services in Malaysia.
Impact of Employees' Perceived Corporate Social Responsibility on Organizational Citizenship Behavior
Authors: Fatima Tahniyath
Published: May 2020

Perceived reality plays a more prominent role in shaping one's attitudes and behaviors than the actual reality itself. Research on perceived corporate social responsibility (PCSR) has gained interest and this research study examines the specific relationship of PCSR with a discretionary behavioral construct, organizational citizenship behavior (OCB). Building upon social theories such as the social identity theory, social exchange theory, social learning theory, and social attribution theory, a conceptual framework is proposed that identifies the impact of internal and external moderators on the PCSR-OCB relationship. Through proposing the impact of external moderators, the researcher aims to bring in objectivity when assessing PCSR, a subjective construct. Further contributions to research and practitioners are highlighted and future avenues for research are discussed.
An Osmosis-Based Intelligent Agent Scheduling Framework for Cloud Bursting in a Hybrid Cloud
Authors: Hepsiba Preethi Sheba , Grace Mary Kanaga E.
Published: May 2020

An intelligent system to efficiently provision resources in a hybrid cloud environment is necessary due to the high level of complexity. The semi-permeable agent for hybrid cloud scheduling (SPAH) is a bio-inspired agent that adapts the biological process of osmosis into cloud bursting. The primary objective of the agent is to minimize the makespan. The framework and algorithm for the two phases of SPAH, to recognize the state and decide on action are presented. A QoS (Quality of Service) deadline factor metric is proposed to study the indirect impact of SPAH in deadline satisfaction. SPAH shows significant improvement in deadline satisfaction of up to 85% as compared to other cloud bursting techniques. This is the result of a reduced makespan and a reduced cumulative waiting time. The analysis of SPAH shows that it works in quadratic time complexity.
A Novel Method for Classifying Function of Spatial Regions Based on Two Sets of Characteristics Indicated by Trajectories
Authors: Zhang Haitao , Yu Chenguang , Jin Yan
Published: May 2020

Trajectory is a significant factor for classifying functions of spatial regions. Many spatial classification methods use trajectories to detect buildings and districts in urban settings. However, methods that only take into consideration the local spatiotemporal characteristics indicated by trajectories may generate inaccurate results. In this article, a novel method for classifying function of spatial regions based on two sets of characteristics indicated by trajectories is proposed, in which the local spatiotemporal characteristics as well as the global connection characteristics are obtained through two sets of calculations. The method was evaluated in two experiments: one that measured changes in the classification metric through a splits ratio factor, and one that compared the classification performance between the proposed method and methods based on a single set of characteristics. The results showed that the proposed method is more accurate than the two traditional methods, with a precision value of 0.93, a recall value of 0.77, and an F-Measure value of 0.84.
Extending LINE for Network Embedding With Completely Imbalanced Labels
Authors: Wang Zheng , Wang Qiao , Zhu Tanjie , Ye Xiaojun
Published: May 2020

Network embedding is a fundamental problem in network research. Semi-supervised network embedding, which benefits from labeled data, has recently attracted considerable interest. However, existing semi-supervised methods would get biased results in the completely-imbalanced label setting where labeled data cannot cover all classes. This article proposes a novel network embedding method which could benefit from completely-imbalanced labels by approximately guaranteeing both intra-class similarity and inter-class dissimilarity. In addition, the authors prove and adopt the matrix factorization form of LINE (a famous network embedding method) as the network structure preserving model. Extensive experiments demonstrate the superiority and robustness of this method.
A Boosting-Aided Adaptive Cluster-Based Undersampling Approach for Treatment of Class Imbalance Problem
Authors: Devi Debashree , Namasudra Suyel , Kadry Seifedine
Published: May 2020

The subject of a class imbalance is a well-investigated topic which addresses performance degradation of standard learning models due to uneven distribution of classes in a dataspace. Cluster-based undersampling is a popular solution in the domain which offers to eliminate majority class instances from a definite number of clusters to balance the training data. However, distance-based elimination of instances often got affected by the underlying data distribution. Recently, ensemble learning techniques have emerged as effective solution due to its weighted learning principle of rare instances. In this article, a boosting aided adaptive cluster-based undersampling technique is proposed to facilitate elimination of learning- insignificant majority class instances from the clusters, detected through AdaBoost ensemble learning model. The proposed work is validated with seven existing cluster based undersampling techniques for six binary datasets and three classification models. The experimental results have established the effectives of the proposed technique than the existing methods.

Published: May 2020

The interest in employer branding has increased tremendously over last few decades among practioners and academicians. Organisations have identified employer branding as an important tool for attracting and retaining a talented workforce. It has moved into the heart of the board room and has become a significant strategy for the endurance and sustainability of the organisation in this competitive market. Employer branding has the potential of building relationships across the organisation, but academic works in this area are very limited and little is known about the relationship outcomes of employer branding. Given the relatively recent origin of the concept itself, intention of this article is to get an understanding of employer branding on a broader spectrum and to predict how the relationships are established. The article extensively reviews available literature and delineates major outcomes of it. It also further discusses future implications for researchers in the area of employer branding.

Published: May 2020

The Republic of Turkey is located at the crossroads of many trade and investment routes, converging East with the West and North with the South. However, Turkey is not self-sufficient with respect to capital formation. As a result, it wishes to obtain the deficient part of the capital stock from foreign sources, mainly from foreign direct investment (FDI). The purpose of this paper is to examine the FDI inflows to the Turkish Republic and its effect on economic growth by employing the augmented Dickey-Fuller test, Phillips-Perron, Kwiatkowski, Phillips, Schmidt, Shin unit root tests, and least squares method. The results indicate that FDI inflows to Turkey bring about economic growth.
Decoupling Computation and Result Write-Back for Thread-Level Parallelization
Authors: Hirata Hiroaki , Nunome Atsushi
Published: May 2020

Thread-level speculation (TLS) is an approach to enhance the opportunity of parallelization of programs. A TLS system enables multiple threads to begin the execution of tasks in parallel even if there may be the dependency between tasks. When any dependency violation is detected, the TLS system enforces the violating thread to abort and re-execute the task. So, the frequency of aborts is one of the factors that damage the performance of the speculative execution. This article proposes a new technique named the code shelving, which enables threads not to need to abort. It is available not only for TLS but also as a flexible synchronization technique in conventional and non-speculatively parallel execution. The authors implemented the code shelving on their parallel execution system called Speculative Memory (SM) and verified the effectiveness of the code shelving.
Capturing Spotaneous Software Evolution in a Social Coding Platform With Project-as-a-City Concept
Authors: Toda Koji , Tamada Haruaki , Nakamura Masahide , Matsumoto Kenichi
Published: May 2020

Social coding platforms (SCPs) have realized spontaneous software evolution, where new source code and ideas are spontaneously proposed by altruistic developers. Although there are many projects operated by active communities performing spontaneous evolution, it is yet unclear that how such successful projects and communities have been formed and governed. This article proposes a method that can investigate the history of every project in the SCP. Introducing the concept of project as a city, the authors consider every project in the SCP as a city, where a government and citizens develop a city through collaborative activities. This research then identifies essential attributes that characterize a state of a city. For each attribute, the authors develop metrics that quantify the state S(p; t) of a project p at time t. An experimental evaluation investigating GitHub projects of famous code editors shows that the proposed metrics well visualize the history of the projects from essential perspectives of a city.

In the recent era, a boom was observed in the field of information retrieval from images. Digital images with high contrast are sources of abundant information. The gathered information is useful in the precise detection of an object, event, or anomaly captured in an image scene. Existing systems do uniform distribution of intensities and apply intensity histogram equalization. These improve the characteristics of an image in terms of visual appearance. The problem of over enhancement and the increase in noise level produces undesirable visual artefacts. The use of Otsu's single threshold method in existing systems is inefficient for segmenting an image with multiple objects and complex background. Additionally, these are incapable to improve the yield of the maximum entropy and brightness preservation. The aforementioned limitations motivate us to propose an efficient statistical pipelined approach, the Range Limited Double Threshold Weighted Histogram Equalization (RLDTWHE). This approach is an integration of Otsu's double threshold, dynamic range stretching, weighted distribution, adaptive gamma correction, and homomorphic filtering. It provides optimum contrast enhancement by selecting the best appropriate threshold value for image segmentation. The proposed approach is efficient in the enhancement of low contrast medical MRI images and digital natural scene images. It effectively preserves all essential information recorded in an image. Experimental results prove its efficacy in terms of maximum entropy preservation, brightness preservation, contrast enhancement, and retaining the natural appearance of an image.

Social engineering attacks are becoming serious threats to cloud service. Social engineering attackers could get Cloud service custom privacy information or attack virtual machine images directly. Existing security analysis instruments are difficult to quantify the social engineering attack risk, resulting in invalid defense guidance for social engineering attacks. In this article, a risk analysis framework for social engineering attack is proposed based on user profiling. The framework provides a pathway to quantitatively calculate the possibility of being compromised by social engineering attack and potential loss, so as to effectively complement current security assessment instruments. The frequency of related operations is used to profile and group users for respective risk calculation, and other features such as security awareness and capability of protection mechanism are also considered. Finally, examples are given to illustrate how to use the framework in actual scenario and apply it to security assessment.

Published: May 2020

Aim of the paper is to study the Magnetohydrodynamic boundary layer flow over a cone under the effect of joule heating and viscous dissipation. The surface of the cone is cooled and heated by the flowing fluid having constant temperature along with variable heat transfer coefficient.The surface of the cone is subjected under the convective heat flux. The governing equation for MHD boundary layer flow are non-linear partial differential equations, are transformed into ordinary differential equations using similarity techniques. The reduced ordinary coupled equations are solved with Runge-Kutta’s fourth order method followed by shooting techniques. The effects on flow and heat convection of various physical parameters pertinent to the modeled problem are computed and analyzed and shown through graphs. Keywords: Mixed convection, cone, Boundary layer, Joule Heating, Convective boundary condition.

Published: May 2020

The paper aims to conduct a theoretical analysis about squeeze film behaviour with piezo-viscosity on a fluid lubricated with polar additives on a rigid sphere and a flat porous plate. By taking into account of microcontinum theory of stokes, Barus formula and Darcy’s equations, Reynolds equation in modified form is derived by bearing in mind the variation of viscosity along film thickness. An approximate analytical solution for fluid film pressure, dimensionless load and squeezing time is derived. The results are presented numerically and graphically. To make obvious the accuracy, the results are compared with accessible literature and a remarkable similarity is been reported

The present article examines Soret and Dufour effects on the three-dimensional mixed convective flow of an Oldroyd-B nanoliquid. The flow is caused due to bidirectional stretching of the surface in the presence of an induced magnetic field and heat generation/absorption. Besides, concentration and thermal buoyancy impacts are inspected. The velocity slip, convective and zero nanoparticle mass flux boundary condition at the surface are taken into account. Nonlinear system of equations which are highly coupled is solved via optimal homotopy algorithm. The influence of pertinent parameters on velocity, temperature, and concentration are analyzed graphically. The impact of Dufour number is quite substantial on temperature whereas Soret number increases the concentration. To see the legitimacy of the present work, the present results are compared with the results available in the literature and noted an excellent agreement for the limiting cases.

The objective of the present study was to describe the physical and functioning profile of Brazilian older adults admitted to avascular surgery wards (VSW). This is an observational and cross-sectional study using patients admitted to VSW. The study included subjects considered able to (group 1, G1) or restricted to physical and functional assessment (group 2, G2). Barthel index (BI) was evaluated in G1 and G2 groups, while hand grip strength (HGS), Timed up and Go (TUG), maximal inspiratory and expiratory pressures (MIP and MEP respectively) were assessed only in G1. The data of a total of 104 older adults (G1=56 and G2=48) were analyzed. Most patients had good bed mobility (83.9% in G1 and 75% in G2). There were significant difference between the predicted values and the recorded values obtained for MIP, MEP and HGS (P<0.0001). Pearson correlation showed a significant association between HGS and TUG (P=0.005/r= –0.384) and MEP and TUG (P=0.009/r= –0.353). In conclusion, hospitalized older adults able to perform functional tests showed reduced HGS, MIP and MEP, as well as moderate risk of falls. There was also an association of peripheral muscle strength and expiratory muscle strength with functional mobility evaluated by TUG.

Published: May 2020

A regional 3-D lithostratigraphic model of the Paleozoic bedrock of southern Ontario was completed in
2019. The model encompasses the entire Phanerozoic succession of southern Ontario (110,000 km2), comprised of over 1,400 m of sedimentary strata straddling regional arches/forebulge zones separating the Appalachian Foreland Basin from the Michigan Structural Basin. This ambitious initiative provides
an unprecedented regional 3-D perspective and digital framework and is amenable to numeric modelling of groundwater flow. Conversion to a 3-D hydrostratigraphic model is a future initiative. Model construction is guided by an updated regional lithostratigraphic chart, and utilizes Leapfrog Works -
an implicit modelling application. There are 54 modelled Paleozoic bedrock layers representing 70 formations, plus the Precambrian basement, plus overlying unconsolidated sediments. Borehole records in Ontario's public petroleum well database (www.ogsrlibrary.com) are the principal data source,
supplemented by Ontario Geological Survey (OGS) deep boreholes. A newly revised digital bedrock topography surface combined with revised subcrop geology and digitized 3-D surface polyline and point constraints are used to better align the modelled layers and their extrapolation to the subcrop
surface. The modern topographic surface is integrated using Shuttle Radar Topography Mission (SRTM) DEM data, National Oceanic and Atmospheric Administration (NOAA) lake bathymetry and Canadian Hydrographic data for smaller lakes. Model development is an iterative cycle of interim modelling, expert
geological appraisal, and QA/QC editing of geological data using geophysical logs, drill cuttings, and core, supplemented by manual editing of model layers. From 2015 to 2018, project geologists and geological contract staff of the Oil, Gas and Salt Resources Library completed edits to 30,320
formation tops in a total of 7,490 wells, resulting in a revised dataset and improvements to the petroleum well database. The current and final model (iteration 7) provides a geologically robust representation of regional bedrock geology.

A 3-D model consisting of 7 surficial geology layers overlying bedrock for 66,870 km2 of southern Ontario has been constructed. Model development involved the assembly of a comprehensive subsurface database that includes archival water well and geotechnical
material logs, cored boreholes, and stratigraphically interpreted geophysical data. Other geospatial constraints are derived from topographic Digital Elevation Models (DEM), bathymetric DEMs and depth soundings, a bedrock surface DEM, and seamless surficial geology mapping. Existing sub-regional
(<10,000 km2) higher resolution 3-D models were used to support the model development. The surficial geological legend provided the basis for a simplified stratigraphic layer structure (from oldest to youngest): 1-Bedrock, 2-Lower Sediment, 3-Regional Till, 4-Glaciofluvial Sediment,
5-Upper Till, 6-Glaciolacustrine Mud, 7-Glaciolacustrine Sand, and 8-Recent/Organic Sediment. A preliminary model based on high-quality interpreted data was used along with surficial geological mapping and expert knowledge in a rules-based algorithm to help assign stratigraphic coding to the
widespread, archival material log data. An iterative cycle of automated coding, manual coding, periodic interim model inspection and revision has led to this 3-D surficial geological model. This model supports regional-scale groundwater flow modelling and, along with a companion model of bedrock
geology, will comprise the first complete 3-D model coverage of southern Ontario from the Precambrian basement to post-glacial sediment.
