OBJECTIVE

Primary treatment of hydrocephalus with endoscopic third ventriculostomy (ETV) and choroid plexus cauterization (CPC) is well described in the neurosurgical literature, with wide reported ranges of success and complication rates. The purpose of this study was to describe the safety and efficacy of ETV revision after initial ETV+CPC failure.

METHODS

Prospectively collected data in the Hydrocephalus Clinical Research Network Core Data Project registry were reviewed. Children who underwent ETV+CPC as the initial treatment for hydrocephalus between 2013 and 2019 and in whom the initial ETV+CPC was completed (i.e., not abandoned) were included. Log-rank survival analysis (the primary analysis) was used to compare time to failure (defined as any other surgical treatment for hydrocephalus or death related to hydrocephalus) of initial ETV+CPC versus that of ETV revision by using random-effects modeling to account for the inclusion of patients in both the initial and revision groups. Secondary analysis compared ETV revision to shunt placement after failure of initial ETV+CPC by using the log-rank test, as well as shunt failure after ETV+CPC to that after ETV revision. Cox regression analysis was used to identify predictors of failure among children treated with ETV revision.

RESULTS

The authors identified 521 ETV+CPC procedures that met their inclusion criteria. Ninety-one children underwent ETV revision after ETV+CPC failure. ETV revision had a lower 1-year success rate than initial ETV+CPC (29.5% vs 45%, p < 0.001). ETV revision after initial ETV+CPC failure had a lower success rate than shunting (29.5% vs 77.8%, p < 0.001). Shunt survival after initial ETV+CPC failure was not significantly different from shunt survival after ETV revision failure (p = 0.963). Complication rates were similar for all examined surgical procedures (initial ETV+CPC, ETV revision, ventriculoperitoneal shunt [VPS] placement after ETV+CPC, and VPS placement after ETV revision). Only young age was predictive of ETV revision failure (p = 0.02).

CONCLUSIONS

ETV revision had a significantly lower 1-year success rate than initial ETV+CPC and VPS placement after ETV+CPC. Complication rates were similar for all studied procedures. Younger age, but not time since initial ETV+CPC, was a risk factor for ETV revision failure.

Published: April 2022

OBJECTIVE

The aim of this study was to analyze the best combination of clinical variables associated with concussion subtypes using a multidomain assessment comprising medical history; symptoms; and cognitive, ocular, and vestibular impairment in a cohort of patients presenting to a concussion specialty clinic.

METHODS

Adolescent patients (n = 293) completed demographics and medical history, Concussion Clinical Profiles Screening, Immediate Post-Concussion Assessment and Cognitive Testing, and vestibular ocular motor screening at their first visit (mean 7.6 ± 7.8 days postinjury) to a concussion specialty clinic. Each participant was adjudicated to have one or more subtype (anxiety/mood, cognitive, migraine, ocular, and vestibular) by a healthcare professional based on previously published criteria. A series of backward, stepwise logistic regressions were used to identify significant predictors of concussion subtypes, and predictive probabilities from the logistic regression models were entered into area under the receiver operating characteristic curve (AUC) models.

RESULTS

Each of 5 logistic regression models predicting primary subtypes accounted for 28%–50% of the variance (R2 = 0.28–0.50, p < 0.001) and included 2–8 significant predictors per model. Each of the models significantly differentiated the primary subtype from all other subtypes (AUC = 0.76–0.94, p < 0.001).

CONCLUSIONS

These findings suggest that each concussion subtype can be identified using specific outcomes from a multidomain assessment. Clinicians can employ such an approach to better identify and monitor recovery from subtypes as well as guide interventions.
Stare decisis and information abundance in a common law jurisdiction
Authors: Roscoe Emily , Szypszak Charles
Published: April 2022

In a common law jurisdiction, according to the principle of stare decisis judges are bound to interpret a constitutional or common law principle by applying authoritative cases already decided. Parties in disputes pending before the courts must find and assess the prior cases on which they can expect that judges will rely. Not very long ago, research for such precedent involved reviewing known cases and linking them to other cases using topical digests and citators. Success with this approach required a patient, persistent, thorough, and open-minded methodology. Modern information accessibility gives previously unimaginable quick access to cases, including with tools that promise to predict judicial tendencies. But this technological accessibility can have negative side effects, including a diminished research aptitude and a stilted capacity to synthesize information. It can also lead to an inadequate account of the human factors that often cause judges to depart from predictions based on logical inference from prior cases. This article considers the extent to which the identification of precedent is essential in legal analysis, yet is of limited value in predictability as a result of judges’ unavoidably human perspectives. With examples from landmark cases, the article illustrates that judges sometimes make decisions based on considerations that will not be revealed in a mechanistic application of precedent. The article considers how evolving legal research tools and methods give access to precedent that in some respects makes the process more scientific, but in other respects can obscure the realities of how cases are decided. The article also gives examples of this paradox as demonstrated by today’s students who are learning how to do research, drawn from years of the authors’ teaching experience.

Published: April 2022

The new Schiff base ligand (Z)-2-(methylthio)-N-(pyridin-2-ylmethylene)aniline MPMA derived from pyridine-2- carboxaldehyde and 2- (methylthio) aniline and its Cu(II), Co(II) and Zn(II) metal complexes were prepared and characterized by spectral, magnetic and electrochemical studies. The spectral studies revealed that the ligand MPMA was tridentate and coordinated to the metal through azomethine nitrogen atom, pyridine nitrogen atom and sulphur atom from amine, forming octahedral geometry for Cu2+,Co2+ and tetrahedral geometry for Zn2+ ions. It was further supported by molar conductance measurement, which indicated that the above-mentioned complexes 1 and 2 were formed in 1:2 metal- ligand ratio and complex 3 was formed in 1:1 metal-ligand ratio. The electrochemical study explored that the metal ions undergo quasi reversible redox reactions by two electron transfer processes. The bioefficacy of the Schiff base and their metal complexes were studied in-vitro against the growth of microbes to assess their antimicrobial potential. The antioxidant activity of the ligand and the metal complexes have also been studied. The antidiabetic activity of the ligand and metal complexes were screened against α-amylase enzyme and αglucosidase enzyme and compared with standard drug acarbose.

Published: April 2022

Today, enterprises of various industries, including enterprises in the grain storage industry, are faced with the need for reconstruction, modernization and expansion of production. However, the implementation of such projects is often not possible, since the exact design documentation is either completely absent or outdated and does not meet modern requirements. Moreover, today an increasing number of projects are being carried out in a three-dimensional environment and simple flat drawings are no longer a sufficient basis for design. 3D design is a huge step forward in engineering and its use significantly increases the competitiveness of a design organization in the market. 3D technologies are one of the most important areas of design automation, no one has any doubts about the need to use them both at the design stage and directly during the construction of industrial facilities. Choosing the optimal simulation software is often difficult, as it is not easy to find a program that has all the necessary functionality. In the course of the research we analyzed the possibilities of several popular programs for 3D modeling and the possibility of their use in the process of designing enterprises in the field of grain storage. Thanks to the use of three-dimensional technology, the enterprise gets the opportunity to implement the project in a better quality and in a shorter time, to find errors even before the production of prototypes, and after all, correcting various shortcomings at the design stage is hundreds of times cheaper than at the production stage. Another advantage of 3D models is that they can be transferred to pre-production systems that automatically create programs. This significantly speeds up the production cycle. 3D-design of the elevator becomes a necessity: this is the only way to quickly make a complete virtual model of the elevator with all the nodes, where you can see the route of the grain through the future elevator. This avoids many of the errors that occur when designing only on the basis of a linear model.
ALGORITHM OF FUNCTIONING OF A MACHINE-TRACTOR UNIT USING A FUEL MIXER SUPPLY SYSTEM
Authors:   Vinnytsia National Agrarian University, BURLAKA Serhiy
Published: April 2022

The switching scheme of operation of the machine-tractor unit with the use of the power supply system with the fuel mixer and the electronic control unit on the basis of Arduino Uno is presented. This scheme provides a fully adaptive power supply system for biofuels and their mixtures depending on the load-speed indicators and operating modes. The selection of circuit components is carried out. A linear algorithm for writing a control program for the engine power system has been developed, which ensures its energy efficiency and efficiency of the machine-tractor unit. During the operation of the machine-tractor unit there is a constant change of thermal, loading and speed modes. Internal combustion engines during operation usually operate in unstable modes – start, warm up, acceleration, braking, increase and decrease the load, stop. There is a need to develop a method of controlling the work processes of the diesel engine for its operation on a mixture of BF and PSU with electronic control of the fuel mixture depending on the operating modes. Engines are dynamically asymmetrical objects, ie the processes that take place when increasing and decreasing the load on the crankshaft, when starting and stopping the engine, differ from each other. The development of the algorithm for controlling the working processes of the diesel engine when working on a mixture of BF and PSU with electronic control of the fuel mixture depending on the operating modes of the engine will differ. Technical parameters of the diesel engine and power supply system that must be controlled during operation: torque, crankshaft speed, power, coolant temperature, PSU temperature, percentage of fuel mixture. Fuel consumption refers to economic indicators, to environmental – the composition and amount of harmful emissions. The value of these indicators directly depends on the modes of operation.

The research of different types of Ukrainian national women’s shirts of the Boykiv region at the end of the XIX and the beginning of the XX century about constructive-technological decisions and used colours of materials is carried out in the work. The main types of cut of national shirts of Boykivshchyna have been studied: shirt with shoulder inserts, tunic-like shirt, shirt with one-piece sleeves, shirt with coquette. The authors have developed a classifier of structural elements of the Ukrainian national shirts of Boykivshchyna. Based on the developed classifier, a massive of structural elements of Ukrainian national shirts of Boykivshchyna was formed, which contains information on types of shirt cuts, their silhouettes, length of shirts, types of sleeves by shape and length, types of collars and neck shapes. The proposed massive can be expanded and supplemented, provided that further research will reveal some more structural elements of traditional shirts. Using the structural elements of the massive, it is possible to create new models of modern women’s dresses, introducing them into mass production. Combining design elements, it is possible to create different versions of models of women’s dresses for implementation in multimodal flows. The results of research on determining the colour scheme of materials used for the manufacture of national shirts of Boykivshchyna are presented. It was determined that the most common colours were: blue, beige, white and burgundy. Colours such as red, black, brown, blue, and green were less common. RGB-parameters of shades of colours of materials which are offered to use at designing of the modern women’s dresses made in ethno-style are defined. According to the results of the research, sketches of three models of women’s dresses were developed. Model A of a modern women’s dress, made in ethno style, sewn in industrial conditions.

The article is devoted to the development of a special protective suit for amateur motorcyclists. As a result of the analysis of the operating conditions of motorcyclists’ sportswear, the most negative environmental factors affecting the driver’s body are identified – wind speeds from 0 to 60 km/h, possible precipitation in the form of rain, blunt objects in case of fall. Clothing for amateur motorcyclists should protect the body from the effects of these negative factors, ease of use, comfort at rest and during intense movements. A characteristic feature of the operating conditions of sportswear for motorcyclists is that a person is almost always in a sitting position on a motorcycle. The method of non-contact optical determination of the main poses and characteristic movements of amateur motorcyclists is used in the work. To ensure a given level of ergonomic fit of the motorcyclist’s suit, it is proposed to use the following characteristics: the range of arms of the dressed person; resistance to accuracy and speed of movements; moving areas of clothing relative to the body when moving; tensile deformation of materials in parts, lack of free folds; horizontality of the bottom of the product, the correct position of the sleeve. The “thread method” was chosen to assess the ergonomic conformity of the clothing design. Using this method allows you to measure the amount of movement of individual parts of clothing and stretch material in garments and assess the dynamic compliance of clothing. To determine the air permeability of materials, it is proposed to use the calculation method, which involves determining the coefficient of air permeability by the nature of the weave, the number of threads on the warp and weft and the raw material composition. The areas of location of windproof and shockproof pads are determined. By setting the frequency of occurrence of structural elements and articulations of costumes of professional motorcyclists, the suit model is finally determined: jacket with a stand-up collar, a central zipper and a sewn-on strap, with reliefs; pants on a belt and with a relief. The design of the suit of amateur motorcyclists (sports jacket and pants) was built according to the method of “Mueller and Son”. Further modeling of reliefs, yokes, cuffs and other structural elements was performed.

The article proposes a set of theoretical and practical attributes associated with design decisions regarding the processes of freezing meat products in refrigerators with a large load capacity of industrial refrigerators. A system of intelligent sensors has been developed to control the parameters of the geometry of the carcass of cattle meat and signs of the state of the evaporators of the refrigeration chamber and the refrigeration supply system of an industrial refrigerator. An automatic recognition system has been developed that works in real time and determines: geometric parameters of local and integral sections of the carcass in the form of a plane, radii, length, width, number of contour inflection points, geometric center of image elements; humidity settings. This system constantly analyzes the space of sections of the refrigerating chamber. An intelligent system for neurocontrol of the refrigeration supply of a refrigerating chamber is proposed, in which two video cameras and matrix sensors with piezoelectric elements for assessing the shape of a cattle carcass are mounted; it has been proved that the expert ink image bank allows using reference methods of comparative analysis. Thanks to the interface with information support subsystems, the system provides the operator-technologist with video information and automatically affects the intelligent actuators of compressors, fans, condensers. A system for neuro-fuzzy control of the evaporator freezing process has been developed, which provides for an expert system, a recognition algorithm, an expert image bank of an evaporator with a snow coat and an intelligent mechanism for the impact of ultrasonic vibrations on the surface of a cooling device. A generalized algorithm for the operation of refrigeration control systems for the refrigerating chamber of an industrial refrigerator and a method for its use are presented.

The difficulty of building a tourist route is to give the user the opportunity to build it with interesting tourist attractions. This kind of problem can be classified as a combinatorial optimization problem, the solution of which will be the salesman’s problem in its open version. Solving optimization problems is performed using various algorithms, but they have the following disadvantages: – all algorithms often have limitations of local solutions; – only one solution is used as a source; – each method is quite sensitive to the choice of conditions. The key elements of this technology are the module of choice of tourist places, the module of analysis of responses of other users, the module of planning / modification of a route, the module of forecasting of occurrence of emergency situations. The last module consists of several models of machine learning. All trained models are tested for adequacy and will be used in the future to predict the likelihood of a forest fire. The initial data of the developed system provide the user with an understanding of the situation regarding the probability of a forest fire. Data are calculated as predictions based on the original data and create a forecast for this set of characteristics. As a source, the user will receive an apology visualization in the form of a graph for a specific data set, as well as a map with a prediction for a specific region for easier visual perception. The route planning and navigation system can be used for mobile devices such as PDAs and mobile phones. It includes three main functions: (1) access updated information about the place of interest; (2) plan a specific day for the user according to his / her preferences; (3) user navigation of the selected travel route and dynamic rescheduling. Service-oriented architecture (SOA) in combination with middleware methods and web services is used to design and implement system architecture. The system has a functional personal page of the user, which will display personal information of the user. The page is used to identify the user as well as his preferences. The system has two-factor authorization to log in. All personal data of users is stored in encrypted form and can be securely protected from theft. User authorization is performed at different levels: editing level, viewing level, change monitoring and analysis level.

Predicting dynamic formation pressure using artificial intelligence methods

Determining formation pressure in the well extraction zones is a key task in monitoring the development of hydrocarbon fields. Direct measurements of formation pressure require prolonged well shutdowns, resulting in underproduction and the possibility of technical problems with the subsequent start-up of wells. The impossibility of simultaneous shutdown of all wells of the pool makes it difficult to assess the real energy state of the deposit. This article presents research aimed at developing an indirect method for determining the formation pressure without shutting down the wells for investigation, which enables to determine its value at any time. As a mathematical basis, two artificial intelligence methods are used – multidimensional regression analysis and a neural network. The technique based on the construction of multiple regression equations shows sufficient performance, but high sensitivity to the input data. This technique enables to study the process of formation pressure establishment during different periods of deposit development. Its application is expedient in case of regular actual determinations of indicators used as input data. The technique based on the artificial neural network enables to reliably determine formation pressure even with a minimal set of input data and is implemented as a specially designed software product. The relevant task of continuing the research is to evaluate promising prognostic features of artificial intelligence methods for assessing the energy state of deposits in hydrocarbon extraction zones.

La rehabilitación neuropsicológica es un conjunto de herramientas que hacen parte de la neuropsicología, cuyo objetivo es evaluar e intervenir los impactos acarreados después de un daño cerebral adquirido (DCA). La eficacia de una rehabilitación neuropsicológica depende de múltiples factores, entre ellos la presencia o no de una progresión del daño cerebral, así como las técnicas y los objetivos usados. La rehabilitación neuropsicológica personalizada a cada paciente es aquella que más resultados positivos arroja; sin embargo, no permite generalizar los resultados alcanzados. Las nuevas tecnologías basadas en dispositivos inteligentes permiten reducir esta limitación, por medio de la recolección de una gran cantidad de datos cualitativos y cuantitativos para su posterior análisis e inferencia. El uso de plataformas web puede trasladar el proceso de rehabilitación a los domicilios de las familias e involucrarlas en dicho proceso, pero al mismo tiempo descarga en ellas la función de coterapeuta, lo cual levanta problemas de gestión e impactos en el ecosistema familiar

Rice is a staple food that is generally consumed by mostly Indonesian people. However, in 2020 the productivity of rice plants in Indonesia has decreased. This study aims to determine the effect of yield and production of several varieties of rice grown in various sizes of planting media/pots other than in rice fields. This study was arranged according to a completely randomized design (CRD) with two factors (the first factor was size of planting media/pot, while the second factor was type of rice varieties). There were 3 types size of planting media used, i.e 40x40 cm, 50x50 cm and 60x60cm, while the types of lowland rice varieties used wee Ciherang, Inpari 32 and Mekongga. There were 9 treatment combinations in this study. Each treatment was repeated 3 times, so that 27 experimental pots were obtained. The observational data in this study were analyzed using ANOVA (Diversity Analysis) and then further tested with 5% BNJ. The results of the analysis showed that the treatment of pot size was significantly different to the parameters of plant height at the age of 42 to 112 days after planting. The highest results were obtained from the 50 x 50 (cm) pot size treatment, which was 98.88 cm. Out of the treatment of 60 x 60 (cm) planting media, the results were significantly different for the weight parameter of 1000 grains of rice, with the highest achievement value of 25.66 grams. The highest plant growth was obtained from the treatment of 50 x 50 (cm) planting media which was planted with Ciherang variety, which was 99.66 cm. Meanwhile, the highest production was obtained from the treatment of 60 x 60 (cm) planting media planted with the Inpari 32 variety, which was 26.77 grams.

The manufacturing industry faces significant technical challenges due to the industry 4.0 technologies, which play an essential role in maintenance development. Maintenance in industry 4.0, also named smart maintenance, maintenance 4.0, predictive maintenance, etc., is boosted using industry 4.0 technologies, such as Industrial Internet of Things (IIoT), Big Data and Analytics, Cloud Computing, Augmented Reality (AR), Additive Manufacturing (AM), etc. Previous research presents several smart maintenance technologies, but the manufacturing industry still finds it challenging to implement the technologies cost-effectively. One problem is that there is insufficient research on how smart maintenance technologies can be implemented cost-effectively and add value to the manufacturing industry. Therefore, this paper aims to explore perspectives on smart maintenance technologies: 1) if there are any implemented smart maintenance technologies, 2) in what context, 3) added values, 4) challenges, 5) opportunities, 6) advantages, and 7) disadvantages with the technologies. This paper presents the results of a case study based on an online open questionnaire with respondents working in maintenance organizations in large manufacturing companies.
