Evaluating the usability of a semantic environmental health data framework: Approach and study
Authors: Navarro-Gallinad Albert , Orlandi Fabrizio , Scott Jennifer , Little Mark , O’Sullivan Declan
Published: November 2022

Environmental exposures transported across air, land and water can affect our health making us more susceptible to developing a disease. Therefore, researchers need to face the complex task of integrating environmental exposures and linking them to health events with the relevant spatiotemporal and health context for individuals or populations. We present a usability evaluation approach and study of a semantic framework (i.e. Knowledge Graph, Methodology and User Interface) to enable Health Data Researchers (HDR) to link particular health events with environmental data for rare disease research. The usability study includes 17 HDRs with expertise in health data related to Anti-Neutrophil Cytoplasmic Antibody (ANCA)-associated vasculitis (AAV) in Ireland and Kawasaki Disease in Japan, and with no previous practical experience in using Semantic Web (SW) technologies. The evaluation results are promising in that they indicate that the framework is useful in allowing researchers themselves to link health and environmental data whilst hiding the complexities of SW technologies. As a result of this work, we also discuss the limitations of the approach together with the applicability to other domains. Beyond the direct impact on environmental health studies, the description of the evaluation approach can guide researchers in making SW technologies more accessible to domain experts through usability studies.
PREREQUISITES FOR PREDICTING THE WORK OF PASSIVELY REINFORCED BENDING WOODEN ELEMENTS WITH METALLIC MATERIALS
Authors: Gomon Petro
Published: November 2022

A detailed analysis of literary sources on the strengthening of solid and glued wooden elements of rectangular cross-section was carried out. Based on the literary analysis, the purpose and objectives of the research are given.

It is possible to distinguish two methods of manufacturing reinforced wooden structures: the first method is a passive method of using reinforcement, where reinforcement is used in bending wooden elements without prestressing; the second method is active, where the reinforcement is prestressed in the bending element.

In order to consider this problem comprehensively, it is necessary to have mechanical properties of wood and reinforcement (metallic and non-metallic), mainly deformable and strength characteristics. In particular, such parameters should apply to critical indicators, i.e. indicators that correspond to the maximum stresses of the materials under study.

To establish the stress-strain state of the cross-section of the reinforced element, as well as for the unreinforced element, it is necessary to specify two functions "stress-strain" of wood under axial compression and tension. Also, the two functions of metal work in compression and tension. 

The expediency of reinforcing elements made of solid and glued wood with steel reinforcement is substantiated. The basic prerequisites for the reinforcement of a wooden element working on transverse bending with metal materials have been established. The stress-strain state is established for wooden elements with reinforcement of the compressed and stretched zone. An algorithm has been developed for the use of various functions to determine the stress-strain state of wood, as well as to construct a "moment-curvature" graph for various types of wood reinforcement with metal materials.

The need for further experimental and theoretical research is substantiated.

Authors: Merylovа Іryna
Published: November 2022

The relevance of the article is due to the search for new forms and methods of creating recreation that correspond to the time and social needs. In accordance with the method of experimental design, on the example of the territory of the industrial hub ‘Fabrychnyi’ (Dnipro), the rationality of using the cluster approach to the creation of recreational facilities was demonstrated.

It is noted that the cluster is both a flexible structural unit of the regional system of recreation and tourism, and a self-sufficient form of territorial organization with its own system of connections and relations.

The purpose of the project is to empty the territory from industrial buildings for recreation, as well as to redevelop industrial buildings of historical, architectural and aesthetic value into cultural ones. The main focus of the project is to create an exhibition and museum complex with an ‘open-air museum’ and develop pedestrian infrastructure in the park.

The article considers the possibility of creating a recreational cluster, which will ensure certain continuity of natural framework, regarding its multi-vector formation in the urban structure. This connection of the recreational cluster with water area, will allow reestablishing a pedestrian and recreational framework in the city. It is established that the introduction of a cluster approach will contribute to the greening of the city, and will affect the modeling of ecological infrastructure.
PECULIARITIES OF DETERMINING THE CENTROID OF REGIMEOUS OBJECTS FOR THE ESTABLISHMENT OF SANITARY PROTECTIVE ZONES
Authors: Trehub Mykola , Zuska Ada , Trehub Yuliia
Published: November 2022

Industrial enterprises belong to the group of regime-forming objects (RFO), which most often have a negative impact on the surrounding natural environment. Specialists from various fields are involved in the process of design, definition and formation of sanitary protection zones (SPZ): ecologists, urban planners, land surveyors, surveyors, etc. SPZ must be designed around these objects as part of the urban planning documentation directly from the RFO.

Land managers design the SPZ from the boundary of the land parcel on which the RFO is located, after which they carry out geodetic determination of the boundaries of the SPZ on the area and carry out their state registration as restrictions on the use of land in the State Land Cadastre. In accordance with existing environmental requirements, environmental experts design the SPZ from the centroid of the emission source. Diversity of demands for different professionals require conduction of specific research on accuracy of the position of the centroid of the RFO – emission source.

In this research possible options for the position of the centroid of the emission source depending on the configuration of the RFO, planning models of the SPZ was determined by the authors and substantiated the accuracy of determining the geodetic coordinates of the centroid depending on the method of its determination.

Further research should be continued in order to solve the task of determining the coordinates of the centroid (center) of the RFO based on the results of modern ground measurements without the use of cartographic materials and forming proposals for the development of an appropriate methodology that would satisfy the needs of ecologists and will be suitable for other professionals involved.

Authors: Eroglu Gunet , Köprülü Mertali , Karabacak Berdan
Published: November 2022

The use of mobile apps in diagnosing health conditions has increased in recent years. We need a biomarker detection app for dyslexia because it potentially helps to prevent severe consequences through an early diagnosis that helps provide early intervention. No other research assessed the feasibility and acceptability of using this kind of mobile app to detect dyslexia at home or at school. Here we present a dyslexia biomarker detection app based on Z-scored QEEG data that can be used at home or school and has accomplished a high accuracy rate in diagnosing dyslexia. The mobile app can be used at home by parents or teachers at school. We have collected data from 207 children (96 of them have dyslexia, 111 of them are typically developing) between 7-10 years old for 60 sessions. The data consists of the eyes-open resting state 2-minute QEEG data from 14-channels. Using the ANN machine learning method, children with dyslexia/ typically developing children (TDC) classification has been done with a high accuracy rate (98.8%). ANN yields the highest accuracy results with standardized QEEG data in the literature. A survey is created to assess the dyslexia biomarker detection app’s feasibility, acceptability, and economic impact. The results have shown that the biomarker detection app is found feasible and acceptable by families, however, it is found expensive to use at home as it includes the EEG headset. So, in order for this ML method to be used extensively at home, EEG headset prices should become more affordable or the method can be used at schools now.

Published: November 2022

Risk is a threat that can disrupt activities or stop the production process. PT.YPT is one of the business entities engaged in the processing of tuna, especially tuna. PT.YPT itself has produced a lot of tuna which cannot be avoided, so risk mitigation is needed. The purpose of this research is to provide risk mitigation from priority risk sources that occur in tuna production activities using the House of Risk (HOR) approach and Fuzzy Logic. Data was collected by means of field observations and literature studies as preliminary research, after which the authors also conducted interviews, brainstorming and distributing questionnaires to internal companies. It can be seen that the risks that can occur in production activities are 23 risk events and 22 risk causes of which 3 risk causes have the highest percentage, namely unskilled operators (A5), less than optimal employee performance (A17) and corrosion of tools (A21). . With the Mamdani fuzzy logic approach that forms 124 IF-THEN rules, it can be seen that the three risks can be solved easily. Mitigation design is carried out to overcome these three risks by making preventive actions as many as 14 mitigation alternatives based on literacy studies and the results of discussions with the company which will be designed in the form of a traceability chart.

The Body As Canvas As Picture
Authors: Jerrentrup Maja Tabea
Published: November 2022

Body painting turns the body into a canvas – this frequently used phrase illustrates the challenge that body painting faces: It uses a three-dimensional surface and has to cope with its irregularities, but also with the model’s abilities, likes and dislikes. After giving an introduction to the art and categorizing its various types and contexts, the article focuses on the European body painting scene and on the role of the model within the scene. Although body painting can be very challenging for her – she has to expose her body and to stand still for a long time while getting transformed – models report that they enjoy the process and the result, even if they are not confident about their own bodies. A reason is that the “double staging“ – becoming a threedimentional work of art and then being staged for a photograph – remotes the body from the model and gives her the chance to see her painted body detached from herself. On the one hand, body painting closely relates to the body, on the other hand, it can help to overcome the body.

The current globalization makes the existence of traditional art lose its true symbolic meaning because artists or artists prefer to follow the market in the process of cultivation. The traditional art of Sandur that still survives by prioritizing grip and symbolic things is the art of Sandur Ronggo Budoyo hamlet, Randu Pokak village, Prunggahan Kulon district, and Semanding Tuban district. The author is interested in researching this because some aesthetic things are studied from the symbolic study of the art of Sandur Ronggo Budoyo. This research uses a qualitative method with a case study approach—descriptive data analysis techniques with data reduction stages, data presentation, and inference. The informants in this study were government, community leaders, traditional art practitioners, and Sandur artists.
