Design and Creation of Multi-Source Enduring Linked Assets
Authors: Ougrinovsk Elena
Published: December 2020

IntroductionThe Australian Institute of Health and Welfare is collaborating with a range of government and other institutions to build enduring data assets for improving analysis and informed policy outcomes. There were lessons learnt that can be shared, in addition to the architecture and linkage techniques.

The enduring assets were created by linking States’ and Territories’ health or welfare data to Commonwealth datasets such as Medicare Consumer Directory (MCD), Residential Aged Care (RAC) and National Death Index (NDI) data. The linkage was carried out by the Australian Institute of Health and Welfare (AIHW) Data Integration Services Centre (DISC).

Objectives and ApproachTo create the integrated asset, the linkage spine was assembled by de-duplicating and linking MCD and NDI data. The states’ datasets and other commonwealth datasets involved in the project were linked to this spine. Each unique individual in the spine was assigned Personal Project Number (PPN) which was added to each record linked to the individual. The unlinked individuals from these datasets were de-duplicated and assigned different PPNs.

Names, dates of birth and addresses were used in probabilistic linkage process.

To enable investigators to interrogate the sequences of the events without releasing the exact dates, the central events file was created. It contains date differences for every event in the asset, calculated as the difference (in days) between event and not released “date zero”, different for each individual.

ResultsBetween 96% and 99% of records in the supplied datasets were linked to the spine with linkage accuracy at least 98.5%. The linkage rates depends on the data completeness and the nature of the datasets as not all individuals accessing states’ servicers are eligible for Medicare.

Conclusion / ImplicationsThe person-focused de-identified analytical assets allow to study journeys of the individual through Australian health and welfare systems which transcends jurisdictional boundaries.
Prescription Benzodiazepine Use During Pregnancy and Risk of Attention-Deficit/Hyperactivity Disorder in Offspring
Authors: Singal Deepa
Published: December 2020

IntroductionBenzodiazepine (BZD) prescribing rates during pregnancy have risen over the last two decades. There is little research into the potential relationship between in utero exposure to BZD and offspring risk of attention deficit/hyperactivity disorder (ADHD), although there is some evidence of negative neurodevelopmental outcomes.

Objectives and ApproachWe used comprehensive linked administrative data to investigate the association between maternal use of prescription BZDs during pregnancy and ADHD in offspring. We included mother-newborn dyads in Manitoba born from 1996-2012, with follow-up through 2017. BZD exposure was defined as 2+ prescriptions between conception and delivery. We matched exposed children to unexposed children to account for differences in characteristics between women who used BZDs during pregnancy versus non-users. Several sensitivity analyses addressed the potential for residual confounding, including a negative control group and a group made entirely of recent users of BZDs. Cox Proportional Hazard Regression Models were used to estimate the risk of ADHD among offspring.

ResultsAmong 495 children with at least two BZD exposures throughout pregnancy, 25.4% (n=452) had a diagnosis of ADHD compared with 18.0% (n=68) of children not exposed (adjusted HR 1.91, 95% CI 1.35-2.69). However, the association was unchanged in the negative control group analyses (aHR 1.76, 1.09-2.86), and not significant in the recent users of BZD (aHR 0.91, 0.63-1.30). Mother’s history of ADHD and teen births were also associated with ADHD in offspring.

ConclusionsIn a large population-level analysis, in utero exposure to prescription BZDs during pregnancy appeared to increase risk of ADHD. However, sensitivity analyses suggest this relationship was likely due to residual confounding. The power to link data for the whole population and across generations enabled powerful sensitivity analyses that alter the initial inference.
Health of Aboriginal Children in Western Australia: Do Grandparents Matter?
Authors: Gibberd Alison , Preen David , Shepherd Carrington , Eades Sandra , McNamara Bridgette
Published: December 2020

IntroductionStudies of select groups (e.g. pre-industrial or subsistence farming populations) suggest that children had improved survival if their grandparents were alive, particularly maternal grandmothers (MGMs). This question is unanswered for Aboriginal Australian communities, where care of children is commonly shared by extended family members, and it is not known if this association holds for physical health in addition to mortality.

Objectives and ApproachWe examined relationships between the health of Aboriginal children born in Western Australia from 2000 to 2013 and the health and vital status of their grandparents. Birth, death, inpatient hospital and emergency department records of all Aboriginal children and their grandparents were linked. Grandparents were categorised as ‘healthy’ (alive with Charlson comorbidity index score of 0 or 1), ‘unhealthy’ (alive with a score of 2 or more), or dead when the child was born.

Results27,425 Aboriginal children linked to their MGM (at a minimum). Mortality up to age 2 was lower with healthy grandparents than unhealthy or dead grandparents (e.g. 11 deaths per 1000 live births with healthy MGM; 22 with unhealthy MGMs and 16 with dead MGMs). Children also had fewer acute healthcare contacts (e.g. 13% with healthy MGMs spent at least 7 days in hospital in their first 2 years compared with 19% with unhealthy or dead MGMs). However, healthcare contacts was largely unrelated to grandfathers. Outcomes were also associated with the number of living grandmothers. (e.g. 1.5% of children with 2 grandmothers were discharged against medical advice in their first 2 years, compared to 2.7% with one healthy grandmother and 3.7% with no grandmothers).

Conclusion / ImplicationsChildren with healthy grandmothers have lower mortality and morbidity, possibly because of their care giving. These associations are unlikely to be due to genetic or environmental factors, as they are weaker or missing for grandfathers.

Published: December 2020

IntroductionLittle is known of the potential impacts of introducing data linkage processes on response rates and biases in school-based surveys.

Objectives and ApproachThis paper assessed: i) the impact on parental consent rates for student participation in a school survey; ii) sample representativeness; and iii) the quality of identifiable data provided to facilitate linkage. An option for data linkage was piloted in a sub-sample of schools participating in the Student Health and Wellbeing survey, a national survey of adolescents in Wales, UK. Schools agreeing to participate were randomized 2:1 to receive the data linkage question. Survey responses from consenting students were anonymised and linked to routine datasets (e.g. general practice, inpatient, and outpatient records). Parental withdrawal rates were calculated for linkage and non-linkage samples. Multilevel logistic regression models compared characteristics between: i) consenters and non-consenters; ii) successfully and unsuccessfully linked students; and iii) linked cohort and peers within the general population, with additional comparisons of mental health diagnoses and health service contacts.

ResultsThe sub-sample comprised 64 eligible schools (out of 193), with data linkage piloted in 39. Parental consent was comparable across linkage and non-linkageschools. 48.7% (n=9,232) of students consented to data linkage. Consenting students were more likely to be younger, more affluent, have higher positive mental wellbeing, and report fewer risk-related behaviours compared to non-consenters. Overall, 69.8% of consenting students were successfully linked, with higher rates of success among younger students. The linked cohort had lower rates of mental health diagnoses (5.8% vs. 8.8%) and specialist contacts (5.2% vs. 7.7%) than general population peers.

ConclusionIntroducing data linkage within a national survey of adolescents had no impact on study completion rates. Students consenting to data linkage, and those successfully linked, differed from non-consenting students on numerous key characteristics, raising questions concerning the representativeness of linked cohorts.

Published: December 2020

IntroductionIn the Western Cape Province of South Africa, a wealth of patient-level data is collected through many separate electronic systems, which share a unique health identifier. However, clinicians primarily access paper folders, which can be unreliable, difficult to locate and are at risk of loss. Patients frequently attend multiple facilities and their information may not be accessible across facilities, hampering continuity of care.

Objectives and ApproachFacilitated by the unique health identifier, a provincial Health Information Exchange (HIE), harmonises patient level data from routine systems into a health information exchange daily. The Single Patient Viewer (SPV) has been developed as a prototype web-based electronic health record and data access portal. SPV integrates clinical data for a single patient both longitudinally and cross-sectionally, in tabular and graphical views, to assist clinicians in rapid information discovery. The application is designed as a web application that calls a multi-purpose API that facilitates interoperability with the HIE.

ResultSPV is in an extended pilot phase with over 200 clinicians using the portal, either for clinical care provision, or for clinical audit activities. The application has evolved to include referral, follow-up (voice call and messaging) and reporting functionality.

In the past 6 months, over 17,000 patients have been viewed with an average daily search of 150 patients. An anonymised user survey with 52 participants showed that users felt that SPV was enjoyable to use, easy to learn, innovative, and supportive and valuable to their work.

Conclusion / ImplicationsSPV has been developed as a global public good project and will be made freely available once matured. A unique feature of the development of SPV is that clinicians were using it while it was being built, enabling constant clinical user feedback. SPV demonstrates the value of integrating health data for clinical viewing while interoperable systems mature.
Methods to Accurately Exclude Renal Dialysis Patients from The Welsh Acute Kidney Injury E-Alert System
Authors: Davies Gareth I , Scale Tim , Akbari Ashley , Chess James , Lyons Ronan A
Published: December 2020

IntroductionAcute Kidney Injury (AKI) effects up to 20% of emergency hospital admissions. It can be identified from serum creatinine (SCr) levels and as such an e-alert system has been introduced to hospitals in England and Wales to identify AKI. This system relies on manual review by pathology laboratory staff to prevent false alerts in dialysis patients.

Objectives and ApproachOur aim is to use routinely collected dialysis timeline and dialysis treatment data in order to create dialysis treatment spells using Structured Query Language (SQL), which can then be compared with dialysis prevalence results in the UK renal registry. Furthermore, we will link this data with biochemical results in Secure Anonymised Information Linkage (SAIL) Databank to create an AKI cohort.

Through identifying when patients are on renal replacement therapy (RRT) at a specific time we are able to exclude false positive AKI Alerts. This is done in two ways – one from a timeline within the data which is used in the UK renal registry. The other using individual dialysis sessions to get accurate coverage, as short periods of acute dialysis are often not been recorded in UK renal registry data.

ResultsUsing the renal dataset in SAIL we were able identify more renal dialysis patients than the UK renal registry between (2009-17). By applying this to Swansea and Bridgend pathology data in SAIL we were able to identify 60,072 SCr tests in dialysis patients between 2011 and 2013 out of 1,776,101 SCr tests. In this cohort, without ruling out dialysis patients there would be 91,140 AKI alerts, however 19.6% (17,855) of the alerts are during dialysis treatments spells.

Conclusion / ImplicationsWe were able to recreate the ‘e-Alert’ algorithm using SQL with SAIL and get an accurate picture of RRT in Wales, enabling more accurate AKI analysis.
Working with Legacy Relational Data in A Graph-Based World
Authors: Farrow James
Published: December 2020

The Next Generation Linkage Management System (NGLMS) was designed around keeping all data in a graph database. However, this constraint, while easily achievable for greenfield projects and/or new data linkage units, may not be easily met where legacy data exists.

Objectives and ApproachThe NGLMS was extended to encompassed system where data was held partially or even completely in a relational database. By grouping the data managed by the NGLMS into system metadata, record link data and record data and allowing system metadata and record data to be stored separately and independently in either a relational or a graph database, the NGLMS allows hybrid installations of mixed graph and relational data and, with some loss of functionality, purely relational installations.

ResultsThe functionality of the NGLMS was expanded to allow review of existing legacy data stored in a relational database system. Through minor changes to the server used by the NGLMS Clerical Review tool (NGLMS-CR) the review tools was able to present the same interface and allow the same integration as project stored completely within the graph database.

Hybrid projects where link information was stored in a graph could be accommodated with no loss of functionality.Relational-only projects allowed clerical review of identified clusters in a manner identical to the graph-only NGLMS but involved some curtailment of the advanced clustering, time-slicing, compositional and concurrent functionality of the NGLMS due to the loss of the functionality provided by a graph database. They do provide an upgrade pathway to hybrid projects and then graph-only projects.

Conclusion / ImplicationsAllowing the NGLMS to be configured as a hybrid system enables a gradual adoption of the NGLMS toolset and software.

purely relational data still allows the use of the NGLMS-CR with customisable workpools and workflows

a hybrid relational/graph system where record data is still kept in a relational store but cluster and linkage information is kept in the graph store allows the use of legacy data without major disruption and provides a pathway to full adoption
Supporting A Developmental Approach for Shared Data Infrastructure
Authors: Nelson Amy Hawn , Berkowitz Emily
Published: December 2020

BackgroundPublic agencies hold important, yet largely unused, administrative data on the families and communities they serve. Integrated Data Systems (IDS) provide the governance process, legal framework, technology, and human capacity to connect these families and communities across data siloes. By securely linking administrative data across siloes, IDS are able to support data-informed decision making.

IntroductionFor 10+ years, AISP has helped jurisdictions through the developmental process of building IDS. We operate a network of 22 U.S. states and counties with fully-functioning Integrated Data Systems, and provide technical assistance to 18 jurisdictions at various stages of IDS development.

Objectives and ApproachThis session presents the outcomes of an independent evaluation of our Learning Community initiative (2019) and presents a new developmental framework that outlines key dimensions of quality and readiness for IDS building and implementation.

ResultsAs of 2020, 20 sites have received formal 18-month cohort based technical assistance. This presentation will discuss site-based approaches to facilitate data sharing, including common challenges and solutions, and progress to date, including findings of an independent evaluation (2019). We will also present a framework developed based on the deep knowledge developed through technical assistance efforts, and findings from a national survey of data integration efforts conducted in 2020.

The framework uses purpose, partnership structure, technical architecture, and organizational model—with respect to the strengths and challenges of each—to categorize and synthesize data integration efforts for social policy and program improvement. The developmental approach to our work emphasizes that we seek to understand methods for sustainability in diverse ways.

Conclusion / ImplicationsWhile there is broad agreement in the value of integrating data across domains, developing the capacity and skills necessary to link administrative data for policy evaluation and research remains an elusive goal. Initial results indicate that an individualized yet collaborative technical assistance approach is successful in developing data integration capacity.

IntroductionSolid organ transplant recipients are at risk of infections, which may be either derived through transplantation or acquired later. Blood-borne viruses (BBV) are a particular concern for donor-derived transmissions. There is an increasing emphasis on biovigilance – monitoring the safety of donated organs. However, systematic surveillance to distinguish donor-transmitted infection from de novo post-transplant infection is challenging. Additional information can be obtained through linkage of administrative health data.

Objectives and ApproachWe aimed to identify donor-transmitted and de novo BBV infections among organ transplant recipients. We conducted a cohort study of all solid organ donor-recipient pairs in New South Wales, Australia, 2000-2015. Donor and recipient BBV infections were identified by linking transplant registries with administrative health data. Proven/probable donor-transmissions were identified among new recipient infections within 12 months of transplant, classified according to an international algorithm. All other new BBV infections were classified as de novo infections.

ResultsAmong 2,120 organ donors, 73 had a BBV infection (11/73 active, 62/73 past). Donors with BBV donated to 176 recipients, of whom 24/176 had the same BBV as their donor, and 152/176 did not; these 152 recipients were at risk of donor-transmission. Among those at risk, there were 3/152 proven/probable BBV transmissions (1 hepatitis C, 2 hepatitis B [HBV]) and 149/152 recipients with non-transmissions. All donor-transmissions were previously recognised by donation services, and were from donors with known BBV. There were no deaths from transmissions. There were 70 recipients with de novo BBV; 2/70 died from new HBV.

Conclusion / ImplicationsThis work confirms the safety of Australian organ donation, with no unrecognised BBV transmissions and many non-transmissions from donors with BBV. This may support increasing targeted donation from donors with BBV. However, de novo BBV infections were substantial and preventable. Data-linkage may be a useful adjunct to current biovigilance systems.

Published: December 2020

IntroductionCanada has one of the highest rates of prescription opioid consumption globally. Little is known about the prevalence and determinants of opioid use among citizens of the Metis nation – one of three Aboriginal groups recognized by the Canadian constitution.
Objectives and ApproachOur objectives were to (i) identify trends in prescription opioid use among Metis citizens from 2006 to 2018 and (ii) identify whether replacing OxyContin with OxyNeo in February 2012 differentially impacted prevalence of opioid use among Metis when compared with all other Manitobans. The Manitoba Metis Federation and the University of Manitoba partnered on this research. We identified prescription opioid use using dispensation records from the province’s drug database, which includes records for all prescription drugs dispensed in community. We defined acute prescription opioid use as ≤28 days prescription and chronic use as ≥ 29 days’ prescription. We tested for differences in annual trends in acute and chronic prescription opioid use between Metis and all other Manitobans. We used an interrupted time series design to test whether replacing OxyContin differentially impacted prevalence of acute and chronic opioid use among Metis when compared with all other Manitobans. We used generalized linear models to test for trends and the impact of replacing OxyContin.
ResultsAcross all years (2006-2018) acute prescription and chronic opioid use was higher among Metis than all other Manitobans. Acute and chronic use decreased in both groups, non-differentially. Replacing OxyContin with OxyNeo was associated with decreased acute opioid use in both Metis and all other Manitobans and had a greater impact on chronic opioid use among Metis than among all other Manitobans. Conclusion / Implications: Findings highlight the differential experiences arising from the historic and ongoing colonial project in Canada, which need to be considered when working to prevent and treat inappropriate Opioid use among Metis.

Objective: To assess primary molars early loss in mixed dentition prevalence. Method: A study was carried out in children aged 6 to 12 years. Deciduous molar loss was considered early when it occurred before Nolla stage 6 (full formed crown) of the permanent successor or one year before its physiological exfoliation. Periapical radiographs were obtained to verify the presence of the permanent successor and the level of root formation, as well as the need for placement of fixed space maintainer lingual arch or Nance button. For the study of frequency distribution of early dental loss in relation to gender and dentition, we used the Chi-square test of 5% probability level and the non-parametric Mann-Whitney test for adequate statistical analysis. Results: Of the 315 children examined, 159 (50.47%) were male and 156 (49.52%) were female. Only 25 (7.9%) presented multiple dental losses in the posterior region, 19 in the lower arch and 6 in the upper arch. In the inferior one there was predominance of first and second deciduous molars loss. There was no difference in the association between genders and the occurrence of multiple dental losses (χ² (1) = 0.03, p>0.05). Conclusion: The prevalence of deciduous teeth premature loss was of 7.9% and the most affected teeth were the first and second molars in the lower arch. Lingual arch space holders were installed in 6 children, who will remain with it until the permanent successors erupt into the oral cavity.

The search for aesthetical Orthodontic treatments alternatives, in addition to technological revolution we are living, have contributed to aligners system to become even more popular. The indication for treatment with aligners is becoming increasingly broad despite several disagreement among orthodontists about the quality of final occlusion. The professional must understand that there are some differences in the force system management of the aligners technique when compared with the fixed appliance. Otherwise, both Orthodontist and patient will see inefficient and limited clinical results. The aim of this article is to present a case report planning using strategies in order to make treatment more efficient and predictable as possible. The patient is 17 years and 9 months old, male with Class I, brachyfacial, whose main complaint was diastemas all over both arches. The orthodontic treatment was performed with Invisalign® aligners with a biomechanical planning, based on movement decomposition and force system simplification. After 3 months and 2 weeks an aesthetic and functional occlusion was obtained with no need for additional aligners or a new digital planning.

The 3DBOT technique (Three-Dimensional Orthodontic Treatment without Brackets) receives this name for performing movements in the 3 dimensions of the space without the use of brackets and with the help of technology through 3D set up. This technique includes advantages such as absolute control of protrusion / retrusion, control of the arch shape and the planned expansion, control of established vertical and anteroposterior movements. It is imperceptible and comfortable, in addition it is a straight and self-ligating technique that allows sliding when necessary. The objective of this work is to report a clinical case of Class II subdivision, using the 3DBOT technique with skeletal anchorage. The combination of the Versatile Skeletal Anchorage Plate on the palate and the 3DBOT technique proved to be a viable option for Class II malocclusion treatment.

Aging is a natural process of the human body. To reduce the signs, several compounds are used that promote the improvement of facial contours, including collagen biostimulators, which act by improving wrinkles, expression lines and facial flaccidity (facial lifiting). Twenty-four scientific articles were used, which fit the following words 'poly-l-lactico', 'radiesse', 'elanse', 'face', and 'rejuvenation', from the platforms PubMed, Scielo and Lilacs in exclusion criteria of 10 years. Sculpra, Ellansé and Radiesse, the main biostimulators in the Brazilian market were presented and also the main characteristics of each one were shown, such as history of the compound, function, action in the organism, method of application, contraindication and adverse reactions and their differences, which guide the choice of material by the professional. The search for aesthetic, non-invasive procedures, in order to circumvent the signs of aging, has been gradually increasing, with this, so we observe the therapy with collagen biostimulators in the Brazilian market, whose main types are Sculpra, Radiesse and Ellansé, which act by stimulating collagen synthesis, and that have all their particularities.
Rehospitalization risk factors for mental health and substance use in Northern British Columbia
Authors:   , Campbell James
Published: December 2020

Mental health and substance use (MH&SU) rehospitalization rates are used as indicators of treatment quality, to reduce costs, and measure efficacy. Research on this topic in rural Canadian hospitals and communities is lacking. This study used secondary data on 5159 patients (age 15 and older) hospitalized with International Classification of Disease (ICD) F code MH&SU diagnosis. These patients had 9103 admissions to 18 hospitals in Northern British Columbia during a five-year period, April 1st, 2010 through March 31st, 2015. ANOVA and Tukey Post Hoc tests were used to examine associations of two performance measures with five patient factors; community size, Indigenous culture, relationship status, employment status, and ICD F code diagnoses. The first measure was number of hospital readmissions. Of the 5159 patients with 9103 admissions, 3482 (67.6%) had one hospital admission during the five-year period. The remaining 1677 (32.4%) patients had 3944 (43.3%) of the hospitalizations). Patients whose cultural identity was Indigenous had over-representation and increased readmissions. Patients who were single and never in a relationship had increased hospitalizations. Patients whose ICD F coding for schizophrenia or psychosis had increased hospitalizations. The second measure was wait time for community MH&SU follow-up. Of the 5159 patients, 4512 (87.5%) had contact with community MH&SU during the five-years. Urban communities with specialized MH&SU services had reduced wait times for follow up. Patients whose cultural identity was Indigenous had longer wait times for community MH&SU follow-up. Patients who were divorced or separated had longer wait times. Patients with ICD F coding for schizophrenia or psychosis had shorter wait times for follow-up. The relationship between hospital readmission and community MH&SU follow-up was examined using logistic regression with the five factors. An inverse relationship was found between the two performance measures. Patients who did not have community MH&SU follow-up within 30 days had reduced odds ratio of readmissions, whereas patients who had follow-up within 30 days had increased odds ratio for readmissions. Although the study finds support for patient risk factors, evidence suggests approaches like a Decision Support Tool (DST) might provide reliability for intervention, and resource planning, as well as timely intervention.
Vocabulary Learning Strategies Among Undergraduate ESL Learners in Tertiary Education
Authors: Abdul Rahman Zarinatun Ilyani , Nasri Nur Farhana
Published: December 2020

Vocabulary learning strategies (VLSs) play a significant role in assisting language learners in the development of language learning. A quantitative study was conducted to explore VLSs employed by undergraduate ESL learners in a public university. Data were collected from a group of 197 ESL learners from three faculties–Accountancy, Applied Science, and Computer and Mathematical Science–in the university. An adopted VLSs questionnaire by Gu & Johnson (1996) was used to answer two research questions: (1) to find the most and least preferred strategies and 2) to identify if there is any significant difference between the ESL learners in three different faculties–Accountancy, Applied Science, and Computer and Mathematical Science - in terms of their vocabulary learning strategies preference. The results were gathered using descriptive analysis and one-way ANOVA followed by a post-hoc test. The results of the study revealed that note taking, memory and guessing using linguistic clues were the three most preferred strategies while guessing using background knowledge and activation were the least preferred ones. In addition, the data also unveiled that there was a significant difference between Accountancy students and Applied Science students as well as Computer and Mathematical Science students both in guessing strategies. It is hoped that the findings of this study can shed some light to the teaching and learning process whereby the educators could employ the best VLSs to assist students in vocabulary learning while learners could be aware of strategies that suit them best.
The Use of Dialogic Principles of Romanian Crowdfunding Platform Communication on Facebook
Authors: VIDRASCU Raluca
Published: December 2020

This study examines how the Romanian crowdfunding platform sprijina.ro is using social media, specifically Facebook, in order to create a dialogic context for consumers, as defined by the five dialogic principles issued by Kent and Taylor (1998). To determine if dialogic communica- tion was occurring between the organization and its followers, the content analysis method was applied to the Facebook page (posts, comments and reactions) of sprijina.ro crowdfunding platform over a 2 years span (2017– 2019). The study attempts to answer the question of whether Romanian crowdfunding platform sprijina.ro applies the principles of dialogic com- munication on their Facebook page. The results show that when applying the dialogic principles, the online audience become more engaged. Unfor- tunately, the majority of posts analyzed ask for money donation without taking into consideration public interest or trying to engage public in the online discussion. This type of communication reflects the lack of strategy in creating and maintaining a dialogic relationship with the online audi- ence through Facebook posts.

This study uses qualitative methods and data was gathered through observation, in-depth interviews, and written material. Data analysis was analyzed using grounded theory approach. the background of a cousin marriage in the Mandar tribe community in Kalola Village is a tradition that has been strong for a long time in the community, in addition to the factor of maintaining a large family and protecting property. Meanwhile, the impact of cousin marriage includes both positive and negative impacts. The positive impact is to reduce the number of conflicts in the community and strengthen local political systems, while the negative impact is the breakdown of kinship in the event of conflict and divorce and health risks.

The analysis and classification of shaping methods in the design of shoe bottom parts, and the investigation of research methods of automation of the design process of shaping shoe bottom parts to increase the efficiency of the design process and reduce the complexity of manufacturing products at the stages of technological preparation. Based on the use of means of transformation and harmonization, the structure of the stages of shaping of art objects to obtain modern shapes was developed, which made it possible to implement a new approach to the artistic design of footwear. On the basis of the developed approaches to the choice of shapes and shaping methods sketches were created and 3D models of shoe bottom parts with the subsequent program analysis of loading on a sole were developed. New shapes shoe bottom parts have been developed with the help of transformation principles and a model has been made by automated design methods, which can be used in technological preparation for the manufacture of light industry products. Regularities of transformation processes for improvement of artistic design of footwear on the principles of bionics and stylization are established. Given that the complexity of structures and the emergence of new spatial solutions pose designers more complex technical tasks for the implementation of design projects, a method was proposed of calculating the strength and stability of products of complex geometric shapes, taking into account the materials from which they are made. As a result of the performed work, women's shoes of the “shuttle” design with an over seam back allowance were developed. Given the fact that the shoes should be comfortable and meet ergonomic indicators, the materials, the shape of the pad, and the design of the model were selected. The purpose of this shoe is everyday wearing, focused on the youth category of consumers. The used technique allows shaping a wide range of various prototypes of footwear, using a small number of transformed products. Determining the most loaded areas made it possible to propose measures to improve the design of shoes of non-standard models. And the combination of the given techniques with modern high-tech production helps to save means of the manufacturer and to increase the service life of footwear.
The acrylic/montmorillonite nanocomposites for leather finishing
Authors: Bondaryeva Аnna , Mokrousova Оlena
Published: December 2020

Leather finishing is carried out by application of coatings that include polymer, pigment, solvents and any auxiliary products. The acrylic resins are employed in leather finishing to produce polymer film to create a uniform protective coating on the leather surface. To increase the operational properties of the polymer coating for leather finishing, it is proposed to use nanocomposites based on acrylic resin and modified dispersions of montmorillonite (AMC). The introduction of montmorillonite allows the polymer to be structured and provides improved physical and mechanical indexes of the leather coating. Acrylic polymers and colored modified dispersions of montmorillonite (CMDM) were used for the study. The colored montmorillonite was obtained by treating water dispersions of montmorillonite by sodium carbonate, basic chromium sulfate and anionic dyes. The AMC contained 1.5–2.0% montmorillonite of the dry polymer residues. The use of AMC enhances the physical and mechanical properties of the leather coating. It is shown that the use of temperature at 60°C for the formation of finishing coating enhances the structuring of the polymer matrix, which is confirmed by the 40 % increase in the tensile strength of films and the 10 % reduction in relative elongation at break.

Textile wastewater effluents are considered one of the most polluting sources, among all industrial sectors, in terms of both effluent volume and composition, with high BOD and COD values. Biochemical Oxygen Demand (BOD) represents the amount of oxygen consumed by bacteria and other microorganisms in decomposing organic matter under aerobic conditions. Chemical Oxygen Demand (COD) represents the measurement of the oxygen required to oxidize soluble and particulate organic matter in water. The main goal of the present study was the investigation in reduction of both BOD and COD concentrations, in a textile wastewater source, using bio-augmented MBBR specific HDPE carriers (composition: 5% talc, 7% cellulose and 88% High-Density-Polyethylene). The HDPE carriers were bio-augmented in an experimental laboratory installation with five fungi microbial strains (either as a mix or individual strain): 3 own microbial isolates (from decaying wood source) and 2 collection strains, namely Cerioporus squamosus (Basidiomycota phylum) and Fusarium oxysporum (Ascomycota phylum). Results showed a reduction rate of COD value of 53.45%, of HDPE carriers bio-augmented in the experimental laboratory installation (mix inoculation), and BOD reduction rates between 28% (carriers bio-augmented with isolate #2) and 61% (carriers bio-augmented with Cerioporus squamosus strain).
